Objectives: The aim of this study is to compare exposure levels of PAHs and benzene metabolites in the urine of nationally representative adults in Korea and identify exposure factors in relation to questionnaire results. Methods: The study analyzed PAHs and benzene metabolites in the urine of adults aged 19 and older recruited in Cycles 1-3 of the Korean National Environmental Health Survey (KoNEHS). Participants were administered questionnaires on demographic characteristics, lifestyle, and dietary habits to identify the association with exposure levels to environmental chemicals. Results: 1-hydroxypyrene and t,t-muconic acid levels in this study were higher than those in large-scale biomonitoring conducted in other countries (the US and Canada), while 2-hydroxynaphthalene levels were lower. Most environmental chemicals exhibited significant differences depending on gender and age, and exposure levels tended to increase with grilled food intake. In addition, variables such as smoking, distance between home and a road, travelling on public transportation, and ventilation time had a significant effect on exposure to environmental chemicals. Conclusions: The importance of this study lies in utilizing the representative results of KoNEHS, large scale biomonitoring conducted in Korea over roughly ten years. Variables including smoking and roasted food intake were found to affect exposure to PAHs and benzene, which can be used to establish baseline exposure levels of environmental chemicals in Korea.

This study analyzed differences and determinants of job satisfaction by employment type using the Korean Labor and Income Panel Data (KLIPS) (5th~13th) and obtained the following results. First, it was found that the job satisfaction of regular employees was significantly higher than that of non-regular employees and, as a result of analyzing job satisfaction by subdividing various types of employment within the non-regular employment category, 'temporary work' was found to have the highest satisfaction, while 'long-term non-regular work' had the lowest. Further, as a result of analyzing the differences in job satisfaction by the method of career choice, it was found that job satisfaction in the case of choosing a job voluntarily was higher than that in the case of choosing a job involuntarily. Second, as a result of analyzing the determinants of job satisfaction by employment type, all variables in regular employment were found to have statistically significant effects on job satisfaction, which is a dependant variable, whereas non-regular employment was found to have a limited effect only depending on the employment type. In case of the determinants of job satisfaction according to the method of career choice, they were found to have statistically significant effects on all variables except for the career variable in the group that chose employment voluntarily, whereas they were found to have significant effects on some variables only such as gender and wage, etc., in the group that chose employment involuntarily. Therefore, it is more suitable to analyze job satisfaction by subdividing it by employment type rather than dividing it into regular employment and non-regular employment, although the method of career choice (voluntary/involuntary) also needs to be considered.

The purpose of this study was to explore the regulations and operational problems of on-board training, and to investigate and analyze the satisfaction level of consignment on-board training among students who completed their training at Korea Maritime & Ocean University. In terms of satisfaction differences by gender, female students generally had a higher relative satisfaction level than male students. The different types of satisfaction in the navigation and engineering categories, the overall practical effect and satisfaction level of the training records shows that the satisfaction level of the trainee is much lower than that of the trainee, so relevant educational institutions and shipping companies need to take measures to improve the satisfaction level of this part. The most important part of the comprehensive company evaluation completed by trainees asked whether they thought the training was equivalent in labor to the employees. Results suggest shipping companies must make a clear distinction between employees and trainees, while establishing relevant internal procedures so that the on-board training process can be carried out in accordance with the purpose of the on-board training consignment.

The effect of body composition such as lean mass and fat mass on bone mineral density (BMD) is complex and still controversial. In this study, we investigated the relationship between body composition and bone mineral density using nation-wide data from 2008 to 2011 Korea National Health and Nutrition Examination Survey (KNHANES) in 2,139 men and 2,193 postmenopausal women aged 50 years or older. Subjects with history of medication for osteoporosis or with diseases or malignancy affecting bone metabolism were excluded. Data of anthropometric measurements and demographic characteristics were collected by trained examiner. Fasting blood sample was obtained for blood chemistry analysis. BMD of the lumbar spine, total femur, and femoral neck, and body composition such as total lean mass (TLM), total fat mass (TFM), truncal fat mass (TrFM) were measured using dual-energy X-ray absorptiometry (DXA). There were significant positive correlations between body composition indices such as lean mass and fat mass with BMD. In multiple regression analysis, TLM was positively associated with BMD after adjusting age, body mass index, monthly house income, education level, physical activity, daily calcium intake and vitamin D concentration in both men and postmenopausal women. BMD at lumbar spine and femur in lowest quartile of TLM was significantly lower than other quartiles after adjusting those confounding factors in both gender. TrFM was negatively associated with total femur BMD in male and femur neck BMD in postmenopausal women after adjusting confounding factors. In conclusion, TLM is very important factor in maintaining BMD in subjects aged 50 years or older in men and postmenopausal women.

In Korean society, words related to misogyny are being created and spread out in the Internet communities and the Internet news posts comments. This study was conducted to investigate if exposure to misogynistic words affects misogynistic attitudes toward women. Study 1 examined the relationship between exposure of misogynistic words (the number of misogynistic words known and the level of Internet comments viewed) and explicit misogynistic attitudes. As a result, the greater the exposure of misogynistic words, the less explicit misogynistic attitudes were found among men. The result can be explained as a desensitization of stimuli caused by repetitive exposure to media. In Study 2, experiments were conducted to manipulate the exposure of misogynistic words and to identify the relationship between implicit misogynistic attitudes through implicit association tests. Results of analysis show that implicit misogyny attitude is stronger as male participants are exposed to misogynistic words. The finding of this study suggests that explicit and implicit attitudes toward misogyny can diverge. It also implies that the exposure to misogynistic words can affect men's and women's attitudes in a different manner.
