Purpose: The purpose of this study was to examine the effect of a moderate-intensity, walking exercise program on the body composition, blood lipids and psychosocial outcomes in postmenopausal obese women. Methods: With a quasi-experimental pre- and post-test design, a total of 36 postmenopausal obese women was recruited in 2 metropolitan areas by convenience sampling. Sixteen women participated in 1 hour of moderate-intensity walking exercise 5 days per week for 3 months and 20 women did not. Cardiovascular risk factors include body composition and blood lipids. Body composition was measured as body mass index, % body fat, and waist/hip ratio; Blood lipids were measured with total cholesterol, triglyceride, HDL and LDL; psychosocial outcomes were evaluated by self-esteem and depression. Results: Over 3 months, the score of self-esteem increased and depression decreased in the exercise group relative to the control group. However, there were no significant differences in body composition and blood lipids. Conclusions: This study suggests that 3 months of moderate-intensity exercise training can improve psychosocial outcomes but further studies are needed to replicate walking exercise on physiologic variables among postmenopausal obese women. These findings are of public health relevance and add a new facet to the growing literature on the health benefits of moderate exercise.

Background: Self-reported low back pain (LBP) has been evaluated in relation to material handling lifting tasks, but little research has focused on relating quantifiable stressors to LBP at the individual level. The National Institute for Occupational Safety and Health (NIOSH) Composite Lifting Index (CLI) has been used to quantify stressors for lifting tasks. A chemical exposure can be readily used as an exposure metric or stressor for chemical risk assessment (RA). Defining and quantifying lifting nonchemical stressors and related adverse responses is more difficult. Stressor-response models appropriate for CLI and LBP associations do not easily fit in common chemical RA modeling techniques (e.g., Benchmark Dose methods), so different approaches were tried. Methods: This work used prospective data from 138 manufacturing workers to consider the linkage of the occupational stressor of material lifting to LBP. The final model used a Bayesian random threshold approach to estimate the probability of an increase in LBP as a threshold step function. Results: Using maximal and mean CLI values, a significant increase in the probability of LBP for values above 1.5 was found. Conclusion: A risk of LBP associated with CLI values > 1.5 existed in this worker population. The relevance for other populations requires further study.

Purpose: The purpose of this study was to develop an instrument to assess nursing professional pride. Methods: Fifty-six preliminary items were identified through literature review and focus group interview of nurses working in a hospital. Of these, 45 preliminary instruments were completed over 0.80 of content validity index. To verify the reliability and validity of the preliminary instrument, data were collected from 294 nurses. The data were analyzed using factor analysis and multidimensional scaling analysis. Results: From the factor analysis, 27 significant items were divided into 5 subscales. These subscales were as follows: feeling of vocation, role satisfaction, role of problem solver, self-achievement, and willingness to stay. The nursing professional pride also established criterion-related validity, discriminant validity, and group validity. Cronbach's α of the instrument was .92, and the subscales ranged from .74 to .85. Conclusion: The developed scale for nursing professional pride shows validity and reliability. The significance of this study is the development of an instrument capable of measuring nursing professional pride. To verify the relevance of this instrument, conducting comparative studies is suggested.

Purpose: This study attempted to compare the metabolic syndrome components, liver function and heathy living habits according to abdominal obesity in male and female workers. Methods: The subjects of this study are 1,078 adult workers who visited N hospital in Incheon for health examination. The data were analyzed using t-test or $x^2$-test with the SPSS/WIN 20.0 program. Results: Prevalence of metabolic syndrome are 22.2% in male workers, and 5.2% in female workers. There were significant differences in 4 metabolic syndrome components (high blood pressure, elevated blood sugar, hypertriglyceridemia, low HDL cholesterolemia), abnormal liver function, and living habits (alcohol drinking) according to abdominal obesity in male workers. There were significant differences in 1 metabolic syndrome component (low HDL cholesterolemia), and abnormal liver function in female workers. Conclusion: It is important to manage all metabolic syndrome components and alcohol drinking in the case of male workers with abdominal obesity, and low HDL cholesterolemia in the case of female workers. Also, occupational nurses should include the relevance between abdominal obesity and liver function index when training health for workers in workplace.

Polycystic ovary syndrome (PCOS) is a common disorder in reproductive-age women. In 2018, an international evidence-based guideline announced recommendations spanning a wide range of issues on the assessment and management of PCOS. From the 166 recommendations, the present study reviews those that are of particular clinical relevance for daily practice and introduces other relevant studies that have been published since the global guideline. The 2018 guideline increased the antral follicle count cutoff for the diagnosis of PCOS from 12 to 20 when using a high-frequency probe. Hirsutism was defined as having a score of ≥4-6 based on a lower percentile of 85%-90% or cluster analysis, which was lower than the traditionally used 95th percentile-based cutoff. The diagnosis of PCOS in adolescents is challenging, and irregular menstruation was defined carefully according to years from menarche. The use of ultrasonography for the diagnosis of PCOS was restricted to those 8 years after menarche. As medication for non-fertility indications, combined oral contraceptives are the first-line drug. Metformin, in addition to lifestyle modifications, should be considered for adult patients with a body mass index ≥25 kg/m² for the management of weight and metabolic outcomes. An aromatase inhibitor is the recommended first-line medication for ovulation induction, a subsequent individual patient data meta-analysis also reported the same conclusion. Whether the new global guideline will be fully adopted by many specialists and change clinical practice is open to question. Further studies are needed to better understand and manage PCOS patients well.

Tidal disruption events (TDEs) provide evidence for quiescent supermassive black holes (SMBHs) in the centers of inactive galaxies. TDEs occur when a star on a parabolic orbit approaches close enough to a SMBH to be disrupted by the tidal force of the SMBH. The subsequent super-Eddington accretion of stellar debris falling back to the SMBH produces a characteristic flare lasting several months. It is theoretically expected that the bolometric light curve decays with time as proportional to $t^{-5/3}$. However, some of the observed X-ray light curves deviate from the $t^{-5/3}$ decay rate, while some of them are overall in good agreement with the $t^{-5/3}$ law. Therefore, it is required to construct the theoretical model for explaining these light curve variations consistently. In this paper, we revisit the mass fallback rates semi-analytically by taking account of the stellar internal structure, orbital eccentricity and penetration factor. We find that the mass fallback rate is shallower than the standard $t^{-5/3}$ decay rate independently of the polytropic index, and the orbital eccentricity only changes the magnitude of the mass fallback rate. Furthermore, the penetration factor significantly can modify the magnitude and variation of mass fallback rate. We confirm these results by performing the computational hydrodynamic simulations. We also discuss the relevance of our model by comparing these results with the observed light curves.
