Abstract
The process of skin aging is intricate, involving intrinsic aging, influenced by internal factors, and extrinsic aging, mainly caused by exposure to UV radiation, resulting in photoaging. Photoaging manifests as skin issues such as wrinkles and discoloration. The skin microbiome, a diverse community of microorganisms on the skin's surface, plays a crucial role in skin protection and can be affected by factors like humidity and pH. Probiotics, beneficial microorganisms, have been investigated for their potential to enhance skin health by regulating the skin microbiome. This can be accomplished through oral probiotics, impacting the gut-skin axis, or topical applications introducing live bacteria to the skin. Probiotics mitigate oxidative stress, suppress inflammation, and maintain the skin's extracellular matrix, ultimately averting skin aging. However, research on probiotics derived from human skin is limited, and there is no established product for preventing photoaging. The mechanism by which probiotics shield the skin microbiome and skin layers from UV radiation remains unclear. Recently, researchers have discovered Lactobacillus in the skin, with reports indicating a decrease in this microorganism with age. In a recent study, scientists isolated Lactobacillus iners KOLBM20 from the skin of individuals in their twenties and confirmed its effectiveness. A comparative analysis of genetic sequences revealed that strain KOLBM20 belongs to the Lactobacillus genus and closely relates to L. iners DSM13335(T) with a 99.20% similarity. Importantly, Lactobacillus iners KOLBM20 displayed anti-wrinkle properties by inhibiting MMP-1. This investigation demonstrated the inhibitory effect of KOLBM20 strain lysate on MMP-1 expression. Moreover, the data suggest that KOLBM20 strain lysate may prevent UVB-induced MMP-1 expression by inhibiting the activation of the ERK, JNK, and p38 signaling pathways induced by UVB. Consequently, KOLBM20 strain lysate holds promise as a potential therapeutic agent for preventing and treating skin photoaging.

Abstract
The process of skin aging is currently recognized as a disease, and extracellular vesicles (EVs) are being used to care for it. While various EVs are present in the market, there is a growing need for research on improving skin conditions through microbial and plant-derived EVs. Edelweiss is a medicinal plant and is currently an endangered species. Callus culture is a method used to protect rare medicinal plants, and recently, research on EVs using callus culture has been underway. In this study, the researchers used LED light to increase the productivity of Edelweiss EVs and confirmed that productivity was enhanced by LED exposure. Additionally, improvements in skin anti-aging indicators were observed. Notably, M-LED significantly elevated callus fresh and dry weight, with a DW/FW ratio of 4.11%, indicating enhanced proliferation. Furthermore, M-LED boosted secondary metabolite production, including a 20% increase in total flavonoids and phenolics. The study explores the influence of M-LED on EV production, revealing a 2.6-fold increase in concentration compared to darkness. This effect is consistent across different plant species (Centella asiatica, Panax ginseng), demonstrating the universality of the phenomenon. M-LED-treated EVs exhibit a concentration-dependent inhibition of reactive oxygen species (ROS) production, surpassing dark-cultured EVs. Extracellular melanin content analysis reveals M-LED-cultured EVs' efficacy in reducing melanin production. Additionally, the expression of key skin proteins (FLG, AQP3, COL1) is significantly higher in fibroblasts treated with M-LED-cultured EVs. These results are expected to provide valuable insights into research on improving the productivity of plant-derived EVs and enhancing skin treatment using plant-derived EVs.

Abstract
PURPOSE/OBJECTIVE(S) Total body irradiation (TBI) has been performed for conditioning before hematopoietic stem cell transplantation. However, TBI can be related to diverse adverse events including radiation pneumonitis and cataract. Efforts to reduce these events include the total marrow irradiation (TMI) and total marrow and lymphoid irradiation (TMLI). Compared to TMI, TMLI requires more target delineations with lymph nodes which can be labor-intensive and time-consuming. However, with the TMI plans, the coverage to lymph node might be lower than TMLI and its clinical significance is unknown. In the current study, we aimed to develop a deep learning model for automatic delineation of whole regional lymph nodes area and assess the dose coverage of lymph nodes with TMI plans. MATERIALS/METHODS Whole regional lymph nodes (cervical, axillary, mediastinal, para-aortic, common iliac, external iliac, internal iliac, obturator, presacral, inguinal lymph nodes) were manually contoured by 3 radiation oncologists in 26 patients having whole body computed tomography (CT) images. Twenty patients were designated as the training/validation set and 6 patients as the testing set, and model was developed using the 'nnUNET' framework. The trained model was evaluated with dice coefficient score (DCS), precision, and recall. In addition, dose coverage of the automatically or manually delineated lymph nodes in TMI plans was calculated. RESULTS The mean value of DCS, precision, and recall of the trained model was 0.76, 0.81, and 0.74, respectively. Dose parameters for manually delineated lymph nodes in previously treated TMI plans showed the mean value of V100% (the percentage of volume receiving 100% of the prescribed dose), V95%, and V90% to be 46.50%, 62.12%, and 73.68%, respectively. The highest V90% was observed in presacral (93.61%), axillary (90.40%), obturator (88.78%), and internal iliac lymph nodes (84.67%). In contrast, the lowest V90% was identified in inguinal (47.95%), cervical (61.69%), and para-aortic (65.75%) and external iliac lymph nodes (68.97%). For automatically delineated lymph nodes, the mean value of V100%, V95%, and V90% of TMI plan was 38.35%, 55.06%, and 67.84%, respectively. The difference with dose coverage of lymph node between delineated manually and automatically was not statistically significant. CONCLUSION Automatic delineation of lymph node using deep learning showed the potential to reduce the labor-intensive process of TMLI. When treated with TMI, the coverage of inguinal, cervical, para-aortic and external iliac lymph nodes was lower than expected.

Abstract
PURPOSE/OBJECTIVE(S) To evaluate the efficacy and safety of image-guided 10-fraction hypofractionated radiotherapy (RT) in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT). MATERIALS/METHODS Between 2016 and March 2022, 69 HCC with PVTT patients received RT (40-50Gy/10fx) in our institutions. The median prescribed dose of 50 Gy (range, 40-50 Gy, BED10; 56-75 Gy10) was delivered in 10 fractions in all patients. Follow-up imaging was performed at three-month intervals after the completion of RT. The extent of PVTT was described according to the Liver Cancer Study Group of Japan classification: Vp0 = no PVTT, Vp1 = segmental portal vein branch, Vp2 = right/left anterior/posterior portal vein, Vp3 = right/left portal vein and Vp4 = main portal vein. Response evaluation was performed using response evaluation criteria in solid tumors, version 1.1. Freedom from local progression (FFLP), progression-free survival (PFS), and overall survival (OS) were calculated from the start date of RT. RESULTS In this cohort, 4.3% of patients had Vp1 PVTT, 20.3% had Vp2, 37.7% had Vp3, and 37.7% had Vp4. The median PTV volume was 105.3 cc (interquartile range [IQR], 74.1-179.4 cc). Fifty-two (75.4%) patients received 50 Gy in 10 fractions. With a median follow-up of 10.2 months (IQR, 6-21 months), the median OS was 18.5 months, and 1-year FFLP, PFS, and OS rates were 84.8%, 26.9%, and 62.2% respectively. At 3 months after RT, 13.0% had a complete response, 36.2% had a partial response, 46.4% had a stable disease and 4.4% had a progressive disease. In the multivariate analysis, AFP ≥ 600 IU/ml (HR 2.06, p = 0.03), Child-Pugh Class B or C (HR 2.30, p = 0.02), and modified Union for International Cancer Control (mUICC) stage IVA or IVB (4.05, p = 0.02) were significantly related to OS. During the follow-up period, there were 2 (2.8%) cases of grade ≥3 toxicity: grade 3 AST/ALT elevation (n = 1), and acute cholangitis (n = 1). CONCLUSION Hypofractionated RT demonstrated promising local PVTT control with acceptable toxicity. These data suggest that 10-fraction image-guided hypofractionated RT (BED10 = 56-75 Gy10) is a feasible treatment option for PVTT in HCC patients.

Abstract
We present a new example of the termination of strike-slip paleoearthquake ruptures in near-surface regions on the Yangsan Fault, Korea, based on multi-scale structural observations. Paleoearthquake ruptures occur mostly along the boundary between the inherited fault core and damage zone (N10-20°E/> 75°SE). The ruptures propagated upward to the shallow subsurface along a < 3-cm-wide specific slip zone with dextral-slip sense, along which the deformation mechanism is characterized mainly by granular flow in near-surface region. The ruptures either reach the surface or are terminated in unconsolidated sediment below the surface. In the latter case, the rupture splays show westward bifurcation, and their geometry and kinematics show a change to NNW-strike with low-angle dip and dextral-reverse oblique-slip sense in the strata. We suggest that the upward termination of the contractional strike-slip ruptures is controlled by the inherited fault geometry that is unfavorable with respect to the stress field (ENE-WSW σHmax) at basement depths in terms of movement on the fault, and the lack of extension of the fault into shallow subsurface; a depth-dependent change in stress from σHmax > σv > σHmin to σHmax > σHmin > σv at depth of a ~ 200 m; and the physical properties of unconsolidated sediment, which have low inter-granular cohesion, resulting in distributed deformation.

Abstract
BACKGROUND Cardiovascular risk is a modifiable factor that can help prevent dementia. Given the dearth of optimal treatment options, managing dementia risk factors is crucial. We examined the association between cardiovascular risk, as measured by the Korean coronary heart disease risk score (KRS), and cognitive function in dementia-free elderly individuals. METHODS We enrolled 8,600 individuals (average age: 69.74 years; 5,206 women) who underwent a medical evaluation from the National Health Insurance Service. KRS was calculated using age, sex, blood pressure, lipid profile, diabetes, and smoking status. Cognitive function was evaluated using Korean Dementia Screening Questionnaire-Cognition (KDSQ-C). Scores of ≥ 6 indicated a cognitive decline. Logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI). Weight, height, stroke history, coronary heart disease history, alcohol consumption, and physical activity engagement were adjusted. RESULTS The lowest, middle, and highest groups, according to the KRS, were 5,923 (68.9%), 2,343 (27.2%), and 334 (3.9%), respectively. The highest KRS group in all participants exhibited a greater risk of cognitive decline than the lowest KRS group (OR, 1.339; 95% CI, 1.034-1.734; P = 0.027). The highest KRS female group aged 71-75 years old exhibited greater cognitive decline than the corresponding lowest KRS group (OR, 1.595; 95% CI, 1.045-2.434; P = 0.031). CONCLUSION Individuals with high cardiovascular risk were associated with poorer cognitive function than those with low risk, especially older women. Cardiovascular risk factors should be carefully managed to promote healthy mental aging in dementia-free elderly individuals.

Abstract
Animal placentae can be used as health-promoting food ingredients with various therapeutic efficacies, but their use is limited by their unpleasant odor and taste. This study aimed to investigate the possibility of deodorization of sheep placenta via yeast fermentation. A yeast strain was successfully isolated and identified as a novel Brettanomyces strain (Brettanomyces deamine kh3). The deodorizing efficacy of fermentation of the sheep placenta with B. deamine kh3 was evaluated by 42 panels, based on evaluation of preference, ranking, and aroma profiles, and compared with normal placenta and placenta fermented with B. bruxellensis. The results of the sensory evaluation indicated that fermentation of the sheep placenta with B. deamine kh3 may improve its palatability by increasing flavors such as that of grass (tree), rubber, and burnt, and by decreasing the odor and soy sauce flavor. Solid-phase microextraction-gas chromatography (SPME-GC) showed that major off-flavors in sheep placenta, such as ammonia, dimethyl disulfide, and 1,3-dioxolane, were completely diminished in the sheep placenta fermented with B. deamine kh3. This study presents those major volatile compounds, including 2-isobutyl\-4,4-dimethyl-1,3-dioxane, and 3-methyl-1-butanol, could be crucial in improving the palatability of the sheep placentae fermented with B. deamine kh3. This study provides a good starting point for the industrial application of a new deodorization method.

Abstract
BACKGROUND Incidence of whooping cough is increasing in Korea. Since 2011, occurrence among adolescents and adults has risen putting vulnerable neonates at risk. National immunization guidelines now include Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) vaccination during pregnancy and as a cocooning strategy (i.e., vaccinating adults and adolescents in contact with neonates). This study assessed post-marketing Tdap (Boostrix®, GSK, Belgium) vaccine safety in subjects ≥ 10 years. METHODS This open, non-comparative multi-center study was conducted over six years at 10 hospitals in Korea. Subjects received Tdap in normal clinical practice according to local prescribing information. All adverse events (AEs) were recorded, classified as expected or unexpected, and severity and relationship to Tdap were assessed. RESULTS The analysis included 672 Korean subjects (mean age, 44 years; range, 11-81), 451 were women and 211 were pregnant. Ninety subjects experienced 124 AEs (incidence 13.39%) of which six were serious AEs (SAEs) assessed as not related to vaccination, and 51 were non-SAEs related to vaccination (mostly administration site reactions). Overall 65/124 AEs were unexpected; the most common were 14 constipation, 5 dyspepsia, 4 common cold and 4 premature labor cases. One case of common cold was assessed as possibly related to vaccination. Pregnancy outcome was 'live infant, no apparent congenital anomaly' in 195 subjects (92.42%) or 'lost to follow-up' in 16 subjects. CONCLUSION Tdap administration to Korean subjects ≥ 10 years, including pregnant women, for the prevention of diphtheria, tetanus and pertussis was shown to have a well-tolerated safety profile.

Abstract
The aim of this study was to probe the influence of continuous nursing intervention on recovery of diabetic patients. From October 2016 to June 2017, 80 diabetic patients who received treatment in our hospital were selected and randomly divided into an intervention group and a control group. The intervention group received continuous nursing care including indirect follow-up, health education and home visit. The self-care ability and blood sugar of the two groups were compared three months later. The score of self-care ability in the intervention group was 89.64±1.64 and that in control group was 72.68±2.47, and a significant difference was observed (P less than 0.001). The fasting blood glucose level in the intervention group was 6.62±0.86 MMOL/L, and the 2-hour post-meal blood glucose level was 8.47±1.32 MMOL/L, which were both lower than those in the control group. Continuous nursing can help monitor the recovery of patients after discharge. It is helpful to improve the self-care ability of patients, control blood sugar level, and promote recovery. It is worth wide promotion.

Abstract
Abstract
Background: Tumor genetic testing (TGT) is increasingly used for planning cancer treatment and identifying appropriate clinical trials. Emerging literature shows that 4–12% of genetic variants identified on TGT are also present in the germline, conferring hereditary cancer risk. Germline genetic testing (GGT) guidelines were recently expanded to include the identification of a BRCA1/BRCA2 variant on TGT as an indication for germline analysis. We evaluated the diagnostic yield of current GGT guidelines by assessing the rate of pathogenic and likely pathogenic (P/LP) germline findings in a series of patients who had a variant identified on TGT and underwent GGT. Methods: We analyzed de-identified data from 185 sequential patients with various tumor types who had TGT and GGT. Personal and family histories were compared to all available NCCN guidelines for GGT. Results: Sixty-four of 185 patients (34.6%) had at least one P/LP germline variant, and among these patients, 42% (27/64) had variants in BRCA1/BRCA2. Variants in all but one patient (26/27) were also found on TGT. Fourteen of 27 (52%) patients had a personal diagnosis of cancer not typically associated with BRCA1/BRCA2, including colorectal (5), lung (3), and one each of cervical, cholangiocarcinoma, gastric, thymus, thyroid, and uterine. Furthermore, prior TGT results were the only reason GGT guidelines were met in 12 of 27 (44%) patients with germline BRCA1/BRCA2 variants. Among 34 patients with a personal history of breast or ovarian cancer, a P/LP germline variant was identified in nine (26%); the majority (5 of 9) were in non-BRCA1/BRCA2 genes including CDKN2A (1), FANCA (1), MUTYH (1), and PALB2 (2). Notably, the patient with the CDKN2A variant did not meet current breast cancer guidelines for GGT, and one patient with breast cancer and a germline BRCA2 mutation only met GGT guidelines due to prior TGT results. Discussion: Genetic testing guidelines have begun to reflect the opportunity for TGT to identify families at risk for hereditary cancer. Expanding GGT criteria to include TGT results is critical for capturing patients who may not otherwise receive GGT. Our data showed a substantial diagnostic yield in patients—including those with breast or ovarian cancer—who completed GGT after variant identification on TGT. Although current genetic testing guidelines capture the portion of these patients with a BRCA1/BRCA2 mutation identified with TGT, our data suggest that P/LP variants in other genes should also be considered during the evaluation of TGT results for subsequent GTG. Finally, the broad spectrum of tumor types with BRCA1/BRCA2 P/LP variants emphasizes the need for all clinicians, regardless of subspecialty, to be aware of current GTG recommendations when TGT identifies a BRCA1/BRCA2 variant and the potential implications of GTG, including targeted therapy, screening, prevention, and family testing.

Abstract
BACKGROUND Metabolic syndrome is associated with cardiovascular diseases and is characterized by insulin resistance. Recent studies suggest that the triglyceride/high-density lipoprotein cholesterol (TG/HDLC) ratio predicts insulin resistance better than individual lipid levels, including TG, total cholesterol, low-density lipoprotein cholesterol (LDLC), or HDLC. We aimed to elucidate the relationship between the TG/HDLC ratio and metabolic syndrome in the general Korean population. METHODS We evaluated the data of adults ≥20 years old who were enrolled in the Korean National Health and Nutrition Examination Survey in 2013 and 2014. Subjects with angina pectoris, myocardial infarction, stroke, or cancer were excluded. Metabolic syndrome was defined by the harmonized definition. We examined the odds ratios (ORs) of metabolic syndrome according to TG/HDLC ratio quartiles using logistic regression analysis (SAS ver. 9.4; SAS Institute Inc., Cary, NC, USA). Weighted complex sample analysis was also conducted. RESULTS We found a significant association between the TG/HDLC ratio and metabolic syndrome. The cutoff value of the TG/HDLC ratio for the fourth quartile was ≥3.52. After adjustment, the OR for metabolic syndrome in the fourth quartile compared with that of the first quartile was 29.65 in men and 20.60 in women (P<0.001). CONCLUSION The TG/HDLC ratio is significantly associated with metabolic syndrome.

Abstract
OBJECTIVES The association between smoking and obesity is a significant public health concern. Both are preventable risk factors of cardiovascular disease and a range of other conditions. However, despite numerous previous studies, no consensus has emerged regarding the effect of smoking on obesity. We therefore carried out a novel study evaluating the relationship between smoking and obesity. METHODS A total of 5,254 subjects aged 19 years or older drawn from the 2010-2013 Korea National Health and Nutrition Examination Survey were included in this cross-sectional study. Smoking was examined both in terms of smoking status and the quantity of cigarettes smoked by current smokers. Multiple logistic regression analysis was used to assess the association between smoking and obesity. Overall obesity was defined as a body mass index (BMI) ≥25 kg/m(2), and central obesity was defined as a waist circumference ≥90 cm for males and ≥85 cm for females. We adjusted for the possible confounding effects of age, sex, physical activity, alcohol consumption, and the presence of hypertension or diabetes. RESULTS A statistically significant difference in central obesity according to smoking status was identified. Current smokers were more likely to be centrally obese than never-smokers (adjusted odds ratio,1.30; 95% confidence interval, 1.02 to 1.67). However, no significant association was found between smoking and obesity defined by BMI. Moreover, among current smokers, no statistically significant association was found between the daily amount of smoking and obesity or central obesity. CONCLUSIONS Smoking was positively associated with central obesity. Current smokers should be acquainted that they may be more prone to central obesity.

Abstract
Background Microalbuminuria and obesity markers are known risk factors for cardiovascular or renal disease. This study aimed to evaluate the prevalence of microalbuminuria according to body mass index (BMI) and abdominal obesity criteria. Methods The study subjects included 3,979 individuals aged 30 years or older who did not have diabetes, hypertension, renal failure, or overt proteinuria, from among those who participated in The Korean National Health and Nutrition Examination Survey in 2013, a cross-sectional, nationally representative, stratified survey. Microalbuminuria was defined as a urinary albumin to creatinine ratio of 30 to 300 mg/g. BMI and waist circumference were classified according to the Asia-Pacific criteria. Results The prevalence of microalbuminuria was found to be 5.1%. In the normoalbuminuria group, 3.4%, 41.7%, 24%, 27.6%, and 3.2% of participants were included in the underweight, normal, overweight, obesity 1, and obesity 2 groups, respectively. These percentages in the microalbuminuria group were 7.1%, 34.5%, 19.2%, 28.6%, and 10.6%, respectively (P<0.001). The waist circumference in men was 21.4% in the normoalbuminuria group and 36.5% in the microalbuminuria group (P=0.004). Logistic regression analyses were performed to evaluate the relationship between the presence of microalbuminuria and BMI or waist circumference groups. The risk of microalbuminuria was significant only in the underweight group (odds ratio, 13.22; 95% confidence interval, 2.55–68.63; P=0.002) after adjusting for confounding factors, abdominal obesity was not significantly associated with microalbuminuria. Conclusion The prevalence of microalbuminuria in a general population in Korea was associated with underweight in men and was not associated with waist circumference in either men or women.

Abstract
Background Overweight and obesity, due to a Westernized diet and lack of exercise, are serious global problems that negatively affect not only personal health, but national economies as well. To solve these problems, preventative-based approaches should be taken rather than medical treatments after the occurrence of disease. The improvement of individual life habits, through continuous care, is thus a paramount, long-term treatment goal. This study describes the effects of ubiquitous health care (uHealth care) or SmartCare services in the treatment of weight loss and obesity. Objective The aim of this study is to evaluate the effect of SmartCare services on weight loss compared to the effects of existing outpatient treatments in obese patients with metabolic syndrome. Methods Metabolic syndrome patients who met the inclusion/exclusion criteria were enrolled in the study and randomized into an intervention or control group. The intervention group was provided with remote monitoring and health care services in addition to the existing treatment. The control group was provided with only the existing treatment. Pedometers were given to all of the patients. Additionally, mobile phones and body composition monitors were provided to the intervention group while body weight scales were provided to the control group. The patients visited the hospitals at 12 and 24 weeks following the baseline examination to receive efficacy and safety evaluations. Results Mean weight reduction from baseline to week 24 was measured as a primary efficacy evaluation parameter and was found to be 2.21 kg (SD 3.60) and 0.77 kg (SD 2.77) in the intervention and control group, respectively. The intervention group had a larger decrement compared to the control group (P<.001). Among the secondary efficacy evaluation parameters, body mass index (BMI) (P<.001), body fat rate (P=.001), decrement of waist measurement (P<.001), and diet habit (P=.012) improvement ratings from baseline to week 24 were found to be superior in the intervention group compared with the control group. The proportion of patients whose body weight decreased by ≥10%, lipid profiles, blood pressure, prevalence of metabolic syndrome, change in the number of metabolic syndrome elements, smoking rate, drinking rate, and physical activity were not statistically significant between the groups. Conclusions The efficacy of SmartCare services was confirmed as the intervention group that received both SmartCare services and the existing treatment had superior results compared with the control group that only received the existing treatment. Importantly, no specific problems with respect to safety concerns were observed. SmartCare service is thus an effective way to control the weight of obese patients with metabolic syndrome.

Abstract
Hyperuricemia has been associated with hypertension, diabetes mellitus, and metabolic
syndrome. We studied the association between hyperuricemia and glycemic status in a
nonrandomized sample of primary care patients. This was a cross-sectional study of
adults ≥20 years old who were members of a community-based health care program.
Hyperuricemia was defined as a value >7.0 mg/dL for men and >6.0 mg/dL for
women. The sample comprised 720 participants including controls (n=257) and patients
who were hypertensive and euglycemic (n=118), prediabetic (n=222), or diabetic
(n=123). The mean age was 42.4±12.5 years, 45% were male, and 30% were white. The
prevalence of hyperuricemia increased from controls (3.9%) to euglycemic hypertension
(7.6%) and prediabetic state (14.0%), with values in prediabetic patients being
statistically different from controls. Overall, diabetic patients had an 11.4%
prevalence of hyperuricemia, which was also statistically different from controls. Of
note, diabetic subjects with glycosuria, who represented 24% of the diabetic
participants, had a null prevalence of hyperuricemia, and statistically higher values
for fractional excretion of uric acid, Na excretion index, and prevalence of
microalbuminuria than those without glycosuria. Participants who were prediabetic or
diabetic but without glycosuria had a similarly elevated prevalence of hyperuricemia.
In contrast, diabetic patients with glycosuria had a null prevalence of hyperuricemia
and excreted more uric acid and Na than diabetic subjects without glycosuria. The
findings can be explained by enhanced proximal tubule reabsorption early in the
course of dysglycemia that decreases with the ensuing glycosuria at the late stage of
the disorder.

Abstract
OBJECTIVE Hypercholesterolemia is a major risk factor for cardiovascular disease and requires continuous management. The role of primary physicians in this regard is important, yet the factors associated with successful lipid lowering treatments in primary clinics have not been clearly identified. We aimed to evaluate the rate of successful hypercholesterolemia treatment in Korean primary care, and to identify the factors associated with achieving low density lipoprotein cholesterol (LDL-C) targets. METHODS We prospectively recruited and retrospectively assessed 1851 Korean patients with hypercholesterolemia who visited family physicians and were prescribed rosuvastatin for the first time. LDL-C lowering targets, defined according to NCEP ATP III guidelines, were evaluated at 6 months after the first prescription. The factors associated with achieving these targets were also assessed. RESULTS Overall, 87.6% of our participants attained their LDL-C goals. In multiple logistic regression analysis, good adherence to medication was strongly associated with the achievement of target LDL-C levels, whereas higher cardiovascular risk factors including diabetes (in both sexes), low high density lipoprotein, and current smoking status (in males), and hypertension (in females) were related to LDL-C target level failures. CONCLUSION Our observations of the short period for hypercholesterolemia in Korean primary care has revealed that the rate of achieving target LDL-C levels was high in these patients, whereas patients at higher risk for cardiovascular disease tended to have lower LDL-C achievement outcomes. Primary care physicians should pay more attention to patients showing higher cardiovascular risk and stress the need for good adherence and management regimens in these individuals.

Abstract
The coadsorption of hydrogen and transition metal dimers Fe2, Co2, Ni2, and FeCo on graphene is investigated using density functional theory calculations. Our work is motivated by observations that the magnetic moments of these transition metal dimers are large and that hydrogen adsorption partitions the graphene lattice into magnetic subdomains. Thus, we expect the magnetic dimers to interact strongly with the lattice. Our results show that the majority-spin direction of the lattice electronic states depends upon the dimer identity, the lattice spin polarization being in the same direction as the dimer spin polarization for Fe2 and FeCo, but opposite for Co2 and Ni2. We can understand this by examining the electronic density of states of the dimer and the lattice. We also show that coadsorption significantly increases the adsorption energies of both dimer and hydrogen leading to a more strongly-adsorbed dimer, while the bond length and magnetic moment of the upper dimer atom, the latter important for potential magnetic storage applications, are negligibly changed. Our work shows that the coadsorbed hydrogen and metal dimer interact over a long-range, this interaction being mediated by the hydrogen-induced spin-polarization of the graphene lattice. We obtain general insight into how the elemental identity of these magnetic dimers determines the spin-polarized states on the hydrogenated graphene lattice. These results could be important for potential applications of magnetic properties of decorated graphene lattices.

Abstract
BACKGROUND Cervical cancer is caused by chronic human papilloma virus (HPV) infection. Pap smear is very efficient examination for early detecting cervical cancer. Inflammation reaction due to chronic infection is one of the major causes of atherosclerosis. Pulse wave velocity (PWV) is commonly used in predicting subclinical atherosclerosis. But no study was done about correlation between cervical cancer and PWV. METHODS The research population, 1,779 people, had been chosen from the patients from Jan. 1st, 2008 to December 31st, 2010, visited health exam center who had done both PWV test and pap smear without any medical history of obstetrics and gynecological disease. The group was divided into two respective groups, 45 people with abnormal finding and 228 people with normal finding. The correlation was analyzed between risk factor of cervical cancer and brachial-ankle PWV. Multiple regression analysis was performed with associated variables. RESULTS Average PWV of normal group was 1,313.06 ± 264.19 and 1,497.15 ± 359.58 was for abnormal. The PWV of abnormal group was statistically significant (p = 0.0006) with association between risk factors of cervical cancer and PWV, age, height, weight, income, gravidity. Multiple regression was done with correcting these variables. PWV was associated with abnormal Pap smear but result, were not found to be significant (p = 0.054). CONCLUSION The result was not statistically confident but more mass studies are needed to correcting those limitation.

Abstract
A novel strain, yH16, was isolated on nutrient agar from soil samples collected at KyungHee University, Suwon City, Republic of Korea. Cells of strain yH16(T) were short rods, Gram-negative-staining, motile and non-spore-forming, with a polar flagellum. Biochemical and molecular characterization revealed that this strain was most similar to Pseudogulbenkiania subflava BP-5(T). Further 16S rRNA gene sequencing studies revealed that the new strain clustered with Pseudogulbenkiania subflava BP-5(T) (95.9 % similarity), Paludibacterium yongneupense 5YN8-15(T) (95.2 % similarity), Gulbenkiania mobilis E4FC31-5(T) (94.6 % similarity) and Chromobacterium aquaticum CC-SE-YA-1(T) (93.9 % similarity). The isolate was able to grow at 25-40 °C, 0.3-2 % NaCl and pH 5.5-7. The DNA G+C content was 65.9 ± 1.0 mol%. The predominant fatty acids were summed feature 3 (C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH) and C(16:0). Ubiquinone 8 was the major respiratory quinone. It was evident from the data obtained that the strain should be classified as a novel species of the genus Pseudogulbenkiania. The name proposed for this taxon is Pseudogulbenkiania gefcensis sp. nov., and the type strain is yH16(T) (=KCCM 90100(T) = JCM 17850(T)).

Abstract
AIM Most studies have reported that circulating levels of adiponectin are negatively correlated with the body mass index (BMI), and hypoadiponectinemia is related to cardiometabolic disorders; however, not all obese subjects have hypoadiponectinemia. The present study investigated circulating adiponectin levels and fat distribution, i.e. subcutaneous fat area (SFA) and visceral fat area (VFA), in obese subjects. METHODS Sixty-eight obese Korean subjects underwent fat distribution by computed tomography (CT) scan and laboratory tests including circulating total adiponectin levels (APN) and circulating high molecular weight adiponectin levels (HMW-APN). RESULTS Log-APN and log-HMW-APN did not correlate with log-BMI either in obese males or females in this study; however, log-APN significantly and negatively correlated with log-VFA both in obese males (r=-0.691, p=0.009) and females (r=-0.319, p=0.002), and log-HMW-APN also correlated negatively with log-VFA both in obese males (r=-0.650, p=0.016) and females (r=-0.370, p=0.005). Log-VFA was a significant determinant of log-APN and log-HMW-APN in obese subjects. In contrast, neither log-APN nor log-HMW-APN was significantly correlated with log-SFA in obese males and females. CONCLUSIONS The present study demonstrated that APN and HMW-APN correlated with VFA, but not BMI and SFA, in obese subjects, and suggest that hypoadiponectinemia may represent dysfunction of adipose tissue in obesity.

Abstract
AIMS A potential role for cardiovascular disease (CVD) risk factors in the aetiology of suicide has not been comprehensively examined. In addition to being small in scale and poorly characterized, existing studies very rarely sample Asian populations in whom risk factor-suicide relationships may plausibly differ to Caucasian groups. We examined the association between a series of CVD risk factors and future mortality from suicide. METHODS AND RESULTS The Korean Cancer Prevention Study is a prospective cohort study comprising 1 234 927 individuals (445 022 women) aged 30-95 years with extensive measurement of established CVD risk factors at baseline and subsequent mortality surveillance. Fourteen years of follow-up gave rise to 472 deaths (389 in men and 83 in women) from suicide. After adjustment for a range of covariates, in men, smoking hazard ratio; 95% CI: (current vs. never: 1.69; 1.27, 2.24), alcohol intake (1-24 g/day vs. none: 1.29; 1.00, 1.66), blood cholesterol (≥ 240 vs. <200 mg/dL: 0.54; 0.36, 0.80), body mass index (underweight vs. normal weight: 2.08; 1.26, 3.45), stature [quartile 1(lowest) vs. 4: 1.68; 1.23, 2.30], socioeconomic status [quartile 1(lowest) vs. 4: 1.65; 1.21, 2.24], and martial status (unmarried vs. other: 1.60; 0.83, 3.06) were related to suicide mortality risk. These associations were generally apparent in women, although of lower magnitude. Exercise and blood pressure were not associated with completed suicide. CONCLUSION In this cohort of Korean men and women, a series of CVD risk factors were associated with an elevated risk of future suicide mortality.

Abstract
A genome-wide screen for genetic alterations in radiation-induced thymic lymphomas generated from p53+/- and p53-/- mice showed frequent loss of heterozygosity (LOH) on chromosome 6. Fine mapping of these LOH regions revealed three non-overlapping regions, one of which was refined to a 0.2 Mb interval that contained only the gene encoding homeobox-interacting protein kinase 2 (Hipk2). More than 30% of radiation-induced tumors from both p53+/- and p53-/- mice showed heterozygous loss of one Hipk2 allele. Mice carrying a single inactive allele of Hipk2 in the germline were susceptible to induction of tumors by γ-radiation, but most tumors retained and expressed the wild-type allele, suggesting that Hipk2 is a haploinsufficient tumor suppressor gene for mouse lymphoma development. Heterozygous loss of both Hipk2 and p53 confers strong sensitization to radiation-induced lymphoma. We conclude that Hipk2 is a haploinsufficient lymphoma suppressor gene.

Abstract
Xanthoma disseminatum (XD) is a rare and potentially progressive non-Langerhans-cell histiocytosis. To date, a few cases of XD with spontaneous complete resolution have been described. The present report describes a 16-year-old girl who presented with yellow to red-brown papules and nodules on her eyelids, cheeks, axillae, back and buttocks. Indirect laryngoscopy showed multiple xanthomatous plaques on the larynx, posterior pharynx, epiglottis, and vocal cords. Additional findings were polyuria, polydipsia, and amenorrhea. Skin biopsy and electron microscopy results confirmed the diagnosis of XD. The patient was treated with fenofibrate, simvastatin, desmopressin, and sex-hormone replacement therapy. Her skin lesions began to slowly fade 6 years after disease onset, eventually resolving spontaneously and completely, but leaving an atrophic scar, frank anetoderma, and persisting diabetes insipidus. This case report together with a review of the English-language literature on the long-term follow-up of XD patients provides additional information on the natural history of this disease.

Abstract
PURPOSE The prevalence of metabolic syndrome (MetS) generally varies depending on its diagnostic definition, and many different definitions inevitably lead to substantial confusion and lack of comparability between studies. Despite extensive research, there is still no gold standard for the definition of MetS, which continues to be a matter of debate. In this study, we investigate whether and to what extent its individual components are related to the risk of cardiovascular disease (CVD) in Korean population. MATERIALS AND METHODS We used data from the 2005 Korea National Health and Nutrition Examination Survey, which is a nationally representative survey of the noninstitutionalized civilian population. The study sample consisted of 1,406 Korean adults (587 men, 819 women) who were diagnosed with MetS based on the revised National Cholesterol Education Program (NCEP) criteria. Central obesity is defined as a waist circumference cutoff point reported in Asia-Pacific criteria for obesity based on waist circumference by the World Health Organization. CVD was defined as presence of stroke, myocardial infarction, or angina pectoris on a medical history questionnaire. RESULTS The CVD prevalence among the subjects was 6.8% for men and 8.6% for women. Besides age, the components of MetS showing a significant difference in the number of CVD events were high fasting glucose (FG) in men and high blood pressure (BP) and high FG in women. After adjusting for gender and age, high FG was shown to yield a significant difference (odds ratio: unadjusted 2.08, adjusted 1.81), alone among all MetS components. However, after adjusting for only age, no significant difference was found. CONCLUSION Fasting glucose level is the highest predicting factor for CVD in Korean patients with MetS based on the revised NECP definition.

Abstract
Focused hard X-ray microbeams for use in X-ray nanolithography have been investigated. A 7.5 keV X-ray beam generated at an undulator was focused to about 3 µm using a Fresnel zone plate fabricated on silicon. The focused X-ray beam retains a high degree of collimation owing to the long focal length of the zone plate, which greatly facilitates hard X-ray nanoscale lithography. The focused X-ray microbeam was successfully utilized to fabricate patterns with features as small as 100 nm on a photoresist.

Abstract
BACKGROUND Few studies have examined the effect of insulin resistance on the association between alanine aminotransferase (ALT) and metabolic syndrome. The association between ALT levels and metabolic syndrome were determined, independently of insulin resistance in Korean populations. METHODS AND RESULTS The association between ALT and metabolic syndrome were examined in 28,456 subjects who visited 7 Health Promotion Centers at University Hospitals in Korea from 2006 to 2008. HOMA-IR index was used to represent insulin resistance index. ALT levels were found to be positively associated with metabolic syndrome after adjusting for age, alcohol intake, and smoking status. Furthermore, when additional adjustment was made for insulin resistance, this association between ALT and metabolic syndrome, although slightly attenuated, remained strongly significant. Subjects in the highest ALT quartile were found to have a higher risk of having metabolic syndrome than those in the lowest quartile (odds ratio (OR)=4.45, 95% confidence interval (CI)=3.96-4.99 for men and OR=3.51, 95%CI=2.73-4.52 for women). In addition, the association between ALT level and the risk of metabolic syndrome was significantly higher in the relatively low risk group. CONCLUSIONS ALT levels were found to be significantly associated with metabolic syndrome independently of insulin resistance and with an interaction by age. Further cohort studies are needed to determine the usefulness of ALT levels for predicting the risk of metabolic syndrome.

Abstract
We present a reflection based coherent diffraction imaging method which can be used to reconstruct a non periodic surface image from a diffraction amplitude measured in reflection geometry. Using a He-Ne laser, we demonstrated that a surface image can be reconstructed solely from the reflected intensity from a surface without relying on any prior knowledge of the sample object or the object support. The reconstructed phase image of the exit wave is particularly interesting since it can be used to obtain quantitative information of the surface depth profile or the phase change during the reflection process. We believe that this work will broaden the application areas of coherent diffraction imaging techniques using light sources with limited penetration depth.

Abstract
OBJECTIVE To present our experience with vagus nerve stimulation (VNS) and to evaluate the long-term efficacy and safety of the procedure in pediatric intractable epilepsy. METHODS This study included sixteen patients, who were implanted with a vagus nerve stimulator and could be followed up for at least more than 12 months in two epilepsy centers. Data including seizure frequency, EEG, quality of life measures and adverse events were prospectively filed over a 5-year period. RESULTS VNS resulted in a > 50% reduction in seizure frequency in 50.0% (8/16) of children with 31.3% (5/16) of patients achieving a > 90% reduction. Additionally, enhancements in quality of life were as follows: memory in 50.0% (8/16), mood in 62.5% (10/16), behavior in 68.8% (11/16), alertness in 68.8% (11/16), achievement in 37.5% (6/16), and verbal skills in 43.8% (7/16) of the patients. Adverse events included hoarseness in two patients, dyspnea during sleep in two patients, and sialorrhea in one patient. However, these events were tolerable or could be controlled by the adjustment of output currents. In one patient, wound revision was required. CONCLUSION Our data supports the role of VNS as an alternative therapy for pediatric intractable epilepsy.

Abstract
OBJECTIVE To examine whether the perinatal mortality of infants born during holidays differs from that of infants born on workdays, and to elucidate its cause. DESIGN Cross-sectional study. Setting Vital statistics linked to the National Infant Mortality Survey data for 1999 births in Korea. POPULATION In all, 628 485 births in 1999 in Korea. METHODS Number of births and perinatal mortality were classified according to the day of the week using the occurrence index. After adjusting for confounding factors, the odds ratios (ORs) for increased holiday mortality were estimated using logistic regression. MAIN OUTCOME MEASURE Birthweight-adjusted perinatal mortality. RESULTS Births on holidays were 33% fewer and perinatal deaths 24% higher than expected (PMR, Perinatal Mortality Rate, 16.4 versus 12.8; OR, 1.3; 95% CI, 1.2-1.4). After the adjustment of birthweight, gender, plurality and congenital anomalies, the odds ratio for death of infants born during holidays was 1.2 (95% CI, 1.1-1.3). CONCLUSIONS The higher perinatal mortality during holidays in Korea appears to be due to different qualities of perinatal care, rather than difference in case-mix.

Abstract
The phentermine, an appetite suppressant, has been widely applied in Korea since 2004. However, there have been relatively few reports about the efficacy and the safety of phentermine in Korea. The aim of this study is to verify the effect of phentermine on weight reduction and the safety in Korean patients. This randomized, double-blind, placebo- controlled study had been performed between February and July, 2005, in Seoul on 68 relatively healthy obese adults whose body mass index was 25 kg/m2 or greater. They received phentermine-HCl 37.5 mg or placebo once daily with behavioral therapy for obesity. The primary endpoints were the changes of body weight and waist circumference from the baseline in the intention-to-treat population. Mean decrease of both body weight and waist circumference in phentermine-treated subjects were significantly greater than that of placebo group (weight: -6.7 +/- 2.5 kg, p < 0.001; waist circumference: -6.2 +/- 3.5 cm, p < 0.001). Significant number of subjects in phentermine group accomplished weight reduction of 5% or greater from the baseline and 10% or more (p < 0.001). There were no significant differences in systolic and diastolic blood pressure between the groups (p = 0.122 for systolic BP; p = 0.219 for diastolic BP). Dry mouth and insomnia were the only statistically significant adverse events that occurred more frequently in phentermine group. Most side effects of phentermine were mild to moderate in intensity. Short-term phentermine administration induced significant weight reduction and reduction of waist circumference without clinically problematic adverse events on relatively healthy Korean obese people.

Abstract
We report on a type of linear zone plate for nanometer-scale focusing of hard x rays, a multilayer Laue lens (MLL), produced by sectioning a multilayer and illuminating it in Laue diffraction geometry. Because of its large optical depth, a MLL spans the diffraction regimes applicable to a thin Fresnel zone plate and a crystal. Coupled wave theory calculations indicate that focusing to 5 nm or smaller with high efficiency should be possible. Partial MLL structures with outermost zone widths as small as 10 nm have been fabricated and tested with 19.5 keV synchrotron radiation. Focal sizes as small as 30 nm with efficiencies up to 44% are measured.

Abstract
BACKGROUND It is well known that selective serotonin reuptake inhibitors (SSRIs) can cause sexual dysfunction, so it is possible that sibutramine, a serotonin and norepinephrine reuptake inhibitor, could induce sexual dysfunction. DESIGN AND SUBJECTS The effect of sibutramine on sexual function was evaluated in 46 overweight and obese (body mass index (BMI) > or = 23 kg/m2) but otherwise healthy married women (28-44 years). Participants were randomly assigned at baseline to either the sibutramine or control group. The Female Sexual Function Index (FSFI) questionnaire was used to assess sexual function at baseline and after treatment with behavioral therapy plus sibutramine 10 mg once daily or behavioral therapy alone (control) for 8 weeks. RESULTS Mean weight loss from baseline to week 8 was -6.03% in sibutramine group and -0.38% in the control group. There was significant improvement of FSFI total score, arousal domain score and lubrication domain score in the sibutramine group (P<0.05), and significant differences in arousal, orgasm, satisfaction domain score and total score (P<0.05) in favor of sibutramine. Decreases in body weight and BMI were correlated with the improvement of arousal (r = -0.44 and r = -0.48, respectively) and orgasm (r = -0.45 and r = -0.46, respectively) domains. CONCLUSION Treatment with sibutramine plus behavioral therapy did not induce sexual dysfunction and sibutramine-induced weight reduction appeared to have a positive impact on sexual function in this small group of overweight and moderately obese women. The degree of improvement in sexual function was correlated with the degree of weight reduction.

Abstract
The use of alternative medicine for smoking cessation have been increasing steadily in recent years. A series of clinical group studies was performed to clarify the effect, outcome and success rate of an acupuncture treatment for smoking cessation. This study was conducted for four weeks using 238 smoking students at 2 high schools. The subjects were separated into two groups: 159 students were treated with acupuncture on the anti-smoking acupoints of the ear, which is known to be effective for cessation of smoking (case group), and 79 students were treated at other sites of the ear (control group). The acupuncture treatment was alternately administered at each side of the ears on a weekly basis for 4 weeks. The smoking cessation success was only 1 case (0.6%) in the case group and none in the control group after 4 weeks. The change in the taste of tobacco and the intensity of the desire to smoke were not significantly different between the case and control groups, but the case group showed a tendency of reduction in the taste of tobacco and the intensity of the desire to smoke. In addition, the reduction in cigarette consumption was not significant, but the tendency of reduction in the study group was significant. It is believed that the site of auricular acupuncture for smoking cessation is not important. However, there was a significant tendency in terms of the reduction in cigarette consumption, the taste of tobacco and the intensity of the desire to smoke in the case group, indicating that auricular acupuncture in smoking cessation has some effect.
