Abstract
BACKGROUND Nine years have passed since the Journal of Bone Metabolism (JBM) was launched as an English journal in 2012; it was finally included in Scopus in January 2019. Therefore, this study aimed to provide evidence of increased international recognition based on journal metrics and reflect on its efforts to be recognized as a top-notch journal. METHODS Databases, such as the Web of Science (WoS), Scopus, Korean Citation Index (KCI), and citation indicators, including the impact factor (IF) and SCImago journal rank (SJR) were reviewed and calculated according to years, and the results were drawn. Furthermore, country-wise contributions and top-cited articles were also investigated. RESULTS The JBM 2020 IF was 2.17 in the WoS. The 2020 SJR in Scopus was 0.334, with a ranking of 165/219 (75.3%) in the Endocrinology, Diabetes, and Metabolism category. The 2020 KCI was 0.42. Of 263 articles, 260 were citable (98.9%), and of 176 original articles, 15 (8.5%) were supported by research grants. The total citation of JBM has increased from 16 in 2014 to 141 in 2020; however, its KCI remained stationary from 0.29 in 2015 to 0.42 in 2020. CONCLUSIONS Currently, JBM is increasingly cited by international researchers than Korean researchers, indicating that the journal's content is valued at an international level. Its inclusion in PubMed Central appears to have increased its international relevance; however, publishing English-only articles may hinder its use domestically. Therefore, efforts should be made to increase citation rates and enhance domestic readership.

Abstract
Osteoporosis does not take a break while Coronavirus disease 2019 (COVID-19) stunned and overtook everyone’s lives. Medical resources were immediately shifted, self-isolation and telemedicine were expanded, ambulatory care services such as bone densitometry and osteoporosis-centered clinics came to a near halt. Progress with fracture prevention has been challenged because osteoporotic fracture with low energy injury is more prevalent even though restriction of people’s movement. Thus we must re-engage with chronic bone health concerns and fracture prevention. This review discusses challenges in management of osteoporosis during the COVID-19 pandemic and reinforces the need to implementing recommendations concerning the importance of bone fragility care with at least those patients who are already treated with antiosteoporotic drugs maintaining their adherence to treatments.

Abstract
AbstractThis communication describes the results of a potential spin-on glass (SOG) solution for narrow and high aspect ratio trench fill in both shallow trench isolation (STI) and premetal dielectric (PMD) applications. We have focused our development work on a hydrogen silsesquioxane (HSQ, (HSiO3/2)n) material, which offers the advantage of a carbon free gap fill solution. The main challenge for carbon-free SOG materials is to achieve material densification in the nano-scale gaps during thermal processing that of the gap filled material during the wet cleaning steps. This paper reports some approaches and findings on material densification in the nano-scale gaps and the results of subsequent wet etch tests.

Abstract
A chitin-binding protein (CBP) cDNA (CACBP1) was isolated from a cDNA library of pepper (Capsicum annuum L.) leaves infected with Xanthomonas campestris pv. vesicatoria. The deduced amino acid sequence of the CACBP1 gene which has chitin-binding domain and hinge region shares a high level of identity with CBP sequences from tomato, potato and tobacco. The CACBP1 gene was organ-specifically regulated in pepper plants, and differentially induced during the compatible and incompatible interactions of pepper with X. campestris pv. vesicatoria or Phytophthora capsici. Expression of the CACBP1 gene was rapidly induced in the incompatible interactions upon pathogen infection. Transcripts of the CACBP1 gene was highly inducible in the leaves of matured pepper plants by Colletotrichum coccodes infection. In situ hybridization results showed that CACBP1 mRNA was expressed in the phloem area of vascular bundles in C. coccodes-infected leaf tissues. The pathogen-inducible CACBP1 gene was also strongly induced and accumulated in pepper leaves by ethephon, methyl jasmonate or wounding. These data suggest that ethylene and jasmonate may act as signal molecules in the signal transduction pathways of the CBP gene induction during the pepper defense- or pathogenesis-related plant responses.

Abstract
The antifungal substances SH-1 and SH-2 were isolated from Streptomyces humidus strain S5-55 cultures by various purification procedures and identified as phenylacetic acid and sodium phenylacetate, respectively, based on the nuclear magnetic resonance, electron ionization mass spectral, and inductively coupled plasma mass spectral data. SH-1 and SH-2 completely inhibited the growth of Pythium ultimum, Phytophthora capsici, Rhizoctonia solani, Saccharomyces cerevisiae, and Pseudomonas syringae pv. syringae at concentrations from 10 to 50 microg/ml. The two compounds were as effective as the commercial fungicide metalaxyl in inhibiting spore germination and hyphal growth of P. capsici. However, the in vivo control efficacies of the two antifungal compounds against P. capsici infection on pepper plants were similar to those of H(3)PO(3) and fosetyl-AI but less than that of metalaxyl.

Abstract
A basic beta-1,3-glucanase cDNA clone (CABGLU) was isolated from the cDNA library constructed from hypersensitive response lesions of pepper leaves infected with avirulent strain of Xanthomonas campestris pv. vesicatoria. The deduced polypeptide of CABGLU which contains a C-terminal extension N-glycosylated at a single site characterized as typical structure of class I beta-1,3-glucanase has a high level of identity with tobacco basic beta-1,3-glucanase (77.4%), but only a moderate level of identity with tomato acidic beta-1,3-glucanase (42.6%). Genomic DNA gel blot analysis indicates that the pepper genome contains one or two beta-1,3-glucanase copy genes. Transcripts of the CABGLU gene were more induced in incompatible interactions than in compatible interactions, when inoculated with X. campestris pv. vesicatoria or Phytophthora capsici. Accumulation of CABGLU mRNA was strongly induced in pepper leaves by both ethephon and methyl jasmonate. The CABGLU mRNA was constitutively expressed only in the roots of all the plant organs. These data indicate that the basic beta-1,3-glucanase gene may be induced by pathogen attack and abiotic stresses.

Abstract
A chitinase cDNA clone (designated CAChi2) was isolated from the cDNA library of pepper leaves infected with Xanthomonas campestris pv. vesicatoria. The 1004-bp full-length CAChi2 cDNA encodes a basic chitinase with an N-terminal 24 amino acid signal peptide followed by a catalytic region. An analysis of its sequence indicates that CAChi2 is a class II chitinase, because it does not have chitin-binding domain and C-terminal extension sequences. The deduced amino acid sequence of CAChi2 has a high level of identity with class II chitinases from potato, tomato, tobacco and petunia. Southern analysis demonstrated that the CAChi2 chitinase is encoded by a single or two copy genes in the pepper genome. Following X. campestris pv. vesicatoria or Phytophthora capsici infection, the CAChi2 chitinase mRNA was more highly expressed in the incompatible interaction, compared to expression in the compatible interaction. Treatment with ethylene-releasing ethephon resulted in a strong accumulation of the transcripts in the leaves. In contrast, DL-beta-amino-n-butyric acid, salicylic acid and methyl jasmonate were not effective in inducing CAChi2 transcripts in pepper leaves.

Abstract
The actinomycete strain Ao108 producing antifungal metabolites active against some plant pathogenic fungi was identified as Actinomadura roseola, based on the analyses of morphological and physiological characteristics. The antibiotic Da2B that showed a strong antifungal activity was isolated from the culture broth and mycelial mats of A. roseola strain Ao108 using various chromatographic procedures. On the basis of (1)H NMR, (13)C NMR, and 2-D NMR correlation data, the antibiotic Da2B was confirmed to have the structure of an anthracycline antibiotic, daunomycin. In vitro antimicrobial spectrum tests showed that the antibiotic Da2B had substantial inhibitory activity (10 microg mL(-)(1) of MICs) against mycelial growth of Phytophthora capsici and Rhizoctonia solani. The antibiotic also showed antiyeast activity against Saccharomyces cerevisiae, but the growth of Candida albicans was not affected. Antibacterial activity was found only against Gram-positive bacteria. In the further evaluation of in vivo efficacy, application of the antibiotic Da2B effectively inhibited the development of Phytophthora blight in pepper plants. However, the control efficacy of the antibiotic against Phytophthora infection was somewhat less than that of metalaxyl. The antibiotic Da2B did not show any phytotoxicity on pepper plants even at 500 microg mL(-)(1).

Abstract
Specific cDNAs showing differential expression in bacteria-infected pepper leaves as opposed to healthy leaves were isolated from a pepper cDNA library from hypersensitive response (HR) lesions of leaves infected with an avirulent strain of Xanthomonas campestris pv. vesicatoria. Among a total of 282 cDNA clones tested, 36 individual cDNA genes (13%) hybridized strongly or differentially to the cDNA probes from bacteria-infected leaves. Ten Capsicum Annuum-Induced (CAI) genes encoding putative thionin, lipid transfer protein I and II, osmotin (PR-5), class I chitinase, beta-1,3-glucanase, SAR 8.2, stellacyanin, leucine-rich repeat protein, and auxin-repressed protein were identified. Two CAI genes showed little or no sequence homology to the previously sequenced plant genes. Transcripts of the CAI genes were strongly or preferentially induced in pepper tissues by infection with X. campestris pv. vesicatoria or Phytophthora capsici, and by abiotic elicitor treatment. In particular, most of the CAI genes were strongly induced in pepper tissues by ethephon and methyl jasmonate.

Abstract
The antibiotic Ao58A,which showed strong antifungal activity against some plant pathogenic fungi, was purified from the culture broth and mycelial mats of Micromonospora coerulea strain Ao58 using various chromatographic procedures. The molecular formula of the antibiotic Ao58A was deduced to be C(16)H(23)NO(4) (M + H, m/z 294.1707) by high-resolution FAB mass spectroscopy. Analyses of (1)H NMR, (13)C NMR, and 2D NMR spectral data revealed that the antibiotic Ao58A is the glutarimide antibiotic streptimidone, 4-(2-hydroxy-5, 7-dimethyl-4-oxo-6,8-nonadienyl)-2,6-piperidinedione. The antibiotic Ao58A was very effective in inhibiting growth of Phytophthora capsici,Didymella bryoniae, Magnaporthe grisea, and Botrytis cinerea in the range approximately 3-10 microg mL(-)(1) of MICs. In vivo evaluation of the antibiotic Ao58A under greenhouse condition showed strong control efficacies against the development of P. capsici, B. cinerea, and M. grisea on pepper, cucumber, and rice plants, respectively. The antibiotic Ao58A was equally as effective as metalaxyl, vinclozolin, and tricyclazole in the control of these plant diseases. However, it did not show any phytotoxicity on the plants even when treated with 500 microg mL(-)(1).

Abstract
Differential display techniques were used to isolate cDNA clones corresponding to genes which were expressed in soybean hypocotyls by Phytophthora sojae f.sp. glycines infection. With a partial cDNA clone C20CI4 from the differential display PCR as a probe, a new basic peroxidase cDNA clone, designated GMIPER1, was isolated from a cDNA library of soybean hypocotyls infected with P. sojae f.sp. glycines. Sequence analysis revealed that the peroxidase clone encodes a mature protein of 35,813 Da with a putative signal peptide of 27 amino acids in its N-terminus. The amino acid sequence of the soybean peroxidase GMIPER1 is between 54-75% identical to other plant peroxidases including a soybean seed coat peroxidase. Southern blot analysis indicated that multiple copies of sequences related to GMIPER1 exist in the soybean genome. The mRNAs corresponding to the GMIPER1 cDNA accumulated predominantly in the soybean hypocotyls infected with the incompatible race of P. sojae f.sp. glycines, but were expressed at low levels in the compatible interaction. Soybean GMIPER1 mRNAs were not expressed in hypocotyls, leaves, stems, and roots of soybean seedlings. However, treatments with ethephon, salicylic acid or methyl jasmonate induced the accumulation of the GMIPER1 mRNAs in the different organs of soybean. These results suggest that the GMIPER1 gene encoding a putative pathogen-induced peroxidase may play an important role in induced resistance of soybean to P. sojae f.sp. glycines and in response to various external stresses.

Abstract
Inoculation of soybean (Glycine max L. cv. Jangyup) hypocotyls with Phytophthora sojae f. sp. glycines results in a marked accumulation of some pathogenesis-related (PR) proteins. A basic beta-1,3-glucanase (34 kDa) was purified from soybean hypocotyls infected by an incompatible race of P. sojae f. sp. glycines using CM-cellulose cation exchange chromatography and Bio-gel P-60 gel filtration. The purified soybean beta-1,3-glucanase cross-reacted with polyclonal antibody raised against a tomato beta-1,3-glucanase. The activity of beta-1,3-glucanase was much higher in the infected soybean hypocotyls than the healthy ones. The beta-1, 3-glucanase purified from soybean inhibited spore germination and hyphal growth of the chitin-negative fungus P. sojae f. sp. glycines, but did not show any antifungal activity against the chitin-containing fungi Alternaria mali, Colletotrichum gloeosporioides, and Magnaporthe grisea.

Abstract
In the carboxypeptidase A-catalyzed hydrolysis of O-[trans-alpha-(benzoylamino)-cinnamoyl]-L-beta-phenyllactate (BACPL) or O-[trans-alpha-(benzoylamino)-p-(phenylazo)cinnamoyl]-L-beta-phenyllacta te (BAPACPL), biphasic kinetic behavior was observed due to the accumulation of an intermediate. At -12 degrees C, conversion of the intermediate into the product was much slower than the formation of the intermediate, which accumulated in quantitative amounts. From the absorbance changes observed during the formation process of the intermediate, the concentration of active site of the enzyme was determined.
