Abstract
Introduction and importance Nowadays, improving the performance of employees is essential to increase productivity and achieve continuous improvement; therefore, it is necessary to achieve job satisfaction among all members of the organisation to avoid negative attitudes, professional burnout, health problems and a lack of commitment. Therefore, our objective was to determine the level of burnout and its relationship with the level of job satisfaction among employees in the municipalities of southern Lima. Methods The research is basic research, with a quantitative approach and a cross-sectional, nonexperimental, correlational design. The survey technique was used and the data collection instrument was a questionnaire addressed to 271 workers of the municipalities of South Lima on the variable burnout syndrome with the dimensions depersonalisation and emotional exhaustion, as well as on the variable job satisfaction with the dimensions work benefits, administrative policies and social relations, with a Cronbach's alpha reliability of 0.801. Results The results show that 50.2% of the employees state that they have an overload of mental effort that causes a high level of emotional exhaustion, 50.2% state that the work develops in them negative and insensitive attitudes that increase their level of depersonalisation and 77.9% state that the company is unable to satisfy the personal demands of the employees through the work benefits it offers. Conclusions These findings reflect that burnout is a common illness in organisations due to workload, poor organisational climate and neglect of employees' emotional health. Therefore, more research is needed on the role of organisations in reducing levels of occupational burnout in order to promote improvements in mental health.

Abstract
Natural molecular machines contain protein components that undergo motion relative to each other. Designing such mechanically constrained nanoscale protein architectures with internal degrees of freedom is an outstanding challenge for computational protein design. Here we explore the de novo construction of protein machinery from designed axle and rotor components with internal cyclic or dihedral symmetry. We find that the axle-rotor systems assemble in vitro and in vivo as designed. Using cryo-electron microscopy, we find that these systems populate conformationally variable relative orientations reflecting the symmetry of the coupled components and the computationally designed interface energy landscape. These mechanical systems with internal degrees of freedom are a step toward the design of genetically encodable nanomachines.
