This study examines the factors that influence the chance of getting a full-time tenure track? position in universities in biochemistry. Its main findings are: first, as age at the time of getting a Ph.D. degree increases and the more recent a birth-cohort a female Ph.D. belonged to, the more likely she was likely to get a job; second, the number of citations of publications in science-citation indexed journals during a Ph.D. program period and the number of publications in science-citation indexed journals in post Ph.D. period increased her chance of getting a job; third, a post doctoral program and the duration of Ph.D. training did not affect a chance of getting a job; finally, a Ph.D. from a foreign university and a prestige ranking of a Ph.D. program did not influence a chance of getting a job.

Population dynamics and sexual maturity of Neomysis japonica (Ishikawa and Oshima, 1951) were investigated from a shrimp farm in Tae-an, Korea. N. japonica was collected monthly at the shrimp farm belonging to the Marine and Fisheries Research Institute, the Soonchunhyang University from October 2002 to September 2003. The proportion of female was higher than that of male. The mean carapace length of male (2.42 mm) was larger than that of female (2.31 mm). Brood size increased with increasing female body size. The size of N. japonica at 50% sexual maturity was approximately 4.4 mm. N. japonica females grew faster and reached larger size than males. The mortality rate (z) calculated by length-converted catch curves was $3.46\;yr^{-1}$. The annual recruitment pattern of N. japonica had two major peaks. Log-transformed total length was significantly related with log-transformed carapace length.

According to a rise in leisure time thanks to a five-day workweek system, the population of golf tends to rise day by day as exercise not extreme and doing together with nature, and as a sport with high concentration degree, by virtue of people who have an interest in health care and who strive to enjoy a leisure life. This study targeted the whole male and female golfers who reside in the areas of Seoul and Gyeonggi-do and are now playing golf, carried out sampling, and finally used 485 sheets for analyzing data. The study results were as follows; First, as a result of analyzing the whole lifestyle propensity depending on golfers' gender, it was shown that, as a result of making it type by factor, a male golfer was classified into shopping intention, fashion intention, family intention and tradition intention, and a female golfer was divided into shopping intention, fashion intention, family intention and man-and-woman equality intention. Second, as a result of analyzing a characteristic of gender depending on the standard of selecting goods, it showed the difference between genders as for the standard of selecting goods in case of purchasing golfwear, and it showed the difference in style/design, physique fitness, wearing of a famous golfer, convenience of laundry and management, and functionality, and male golfers were shown to select after seeing the clothes which a famous golfer did wear, compared to female golfers. Also, it could be seen that there was difference depending on the standard of selecting goods and the purchasing propensity in case of buying golfwear.

Using the fourth data of the Korea Labor and Income Panel Study (KLIPS), this paper analyzed sexual differences in the promotion possibility and the promotion experience. Effects on wage of the promotion possibility and the promotion experience have been also discussed in detail. The promotion probability of a male worker in his current job is as high as twice than that of a female worker after controlling other independent variables. However, if we restrict the analysis to workers who either can be or was promoted, the sexual difference in the promotion possibility is greatly narrowed. This result suggests that the continuous career development without disruption is critical for the promotion of female workers. Analysing the sexual difference in wage using Oaxaca and Ransom's methodology, explanatory variables, such as human capital, residential area, etc., explained 69.5% of wage difference between male and female workers. Especially, 13.9% of wage difference was contributed to sexual differences in the promotion possibility and the promotion experience. This kind of empirical result emphasized once again the importance of promotion on wage.

Background: The objective of this study was to elucidate the relationships musculoskeletal pains with combined vulnerability in terms of age, gender, and employment status Methods: The fifth European Working Conditions Survey (EWCS) in 2010 (43,816 participants aged 15 years and over) analyzed for European employees and the third Korean Working Conditions Survey (KWCS) in 2011 (50,032 participants aged 15 years and older) analyzed for Korean employees. In this study, three well known vulnerable factors to musculoskeletal pains (older age, female gender, and precarious employment status) were combined and defined as combined vulnerability. Associations of musculoskeletal pains with combined vulnerability were assessed with prevalence ratios (PRs) and 95% confidence intervals (CIs) estimated by Poisson regression models with robust estimates of variance. Results: The prevalences of musculoskeletal pains were lower but the absolute and relative differences between combined vulnerabilities were higher among Korean employees compared with the European employees. Furthermore, the increased risk of having musculoskeletal pains according to combined vulnerability was modestly explained by socioeconomic factors and exposure to ergonomic risk factors, especially in Republic of Korea. Conclusions: The results of this study showed that the labor market may be more unfavorable for female and elderly workers in Republic of Korea. Any prevention strategies to ward off musculoskeletal pains, therefore, should be found and implemented to mitigate or buffer against the most vulnerable work population, older, female, and precarious employment status, in Republic of Korea.

Objective: To systematically review studies on canine agenesis prevalence in different populations and continents, based on the jaw, sex, location, and associated dental anomalies. Methods: Electronic and hand searches of English literature in PubMed, Web of Science, Scopus, OpenGrey, and Science Direct were conducted, and the authors were contacted when necessary. Observational studies (population-based, hospital/clinic-based, and cross-sectional) were included. For study appraisal and synthesis, duplicate selection was performed independently by two reviewers. Study quality was assessed using a modified Strengthening the Reporting of Observational Studies in Epidemiology checklist, with main outcome of prevalence of canine agenesis. Results: The global population prevalence of canine agenesis was 0.30% (0.0-4.7%), highest in Asia (0.54%), followed by Africa (0.33%), and the least in Europe and South America (0.19% in both continents). Canine agenesis was more common in the maxilla (88.57%), followed by both maxilla and mandible (8.57%), and the least common was mandible-only presentation (2.86%). The condition was more common in females (female:male ratio = 1.23), except in Asia (female:male ratio = 0.88) and Africa (female:male ratio = 1). In Asia, unilateral agenesis was almost twice as prevalent as bilateral, but in Europe, the bilateral form was more common. Conclusions: The overall prevalence of canine agenesis is 0.30%, with the highest prevalence in Asia, followed by Africa, Europe, and South America. The condition is more common in the maxilla than the mandible, and in females than males (except in Asia and Africa), with unilateral agenesis being more common in Asia and the bilateral form showing a greater prevalence in Europe.

Thanks to the popularization of golf, the population of young golfers including female players has been continuously increasing and the market specialization of golf-wear has been gradually intensifying with a growing number of new import brands in the market. This study is aimed to provide a direction to strengthen and invigorate the competitiveness of domestic golf wear brands through research on the benefits pursued by, the purchase attitudes towards local and overseas brands and the purchasing behaviors of female customers who have emerged as the newest customer group in the golf-wear market. The subjects of the research were 409 female golfers and the statistical analyses used for the study were factor analysis, cluster analysis, ANOVA, Scheffe test, and chi-square test. The results showed that there were six factors sought for golf-wear benefits: figure compensation, brand orientation, comfort, youth/fashion, maturity/conformity, and individuality. Cluster analysis showed that there were three groups of golf-wear benefits sought. Overall, the three groups were different in regard to golf involvement and golf-wear preferences. Based upon the results mentioned above, this study summarizes the key features of each group and can provide applicable suggestions for conducting strategic marketing activities.

Objectives: Physical activity behavior begins to decline during adolescence and continues to decrease throughout young adulthood. This study aims to explain factors that influence physical activity behavior in a sample of female adolescents using a health promotion model framework. Methods: This cross-sectional survey was used to explore physical activity behavior among a sample of female adolescents. Participants completed measures of physical activity, perceived self-efficacy, self-esteem, social support, perceived barriers, and perceived affect. Interactions among the variables were examined using path analysis within a covariance modeling framework. Results: The final model accounted for an $R^2$ value of 0.52 for physical activity and offered a good model-data fit. The results indicated that physical activity was predicted by self-esteem (${\beta}$=0.46, p<0.001), perceived self-efficacy (${\beta}$=0.40, p<0.001), social support (${\beta}$=0.24, p<0.001), perceived barriers (${\beta}$=-0.19, p<0.001), and perceived affect (${\beta}$=0.17, p<0.001). Conclusions: The findings of this study showed that the health promotion model was useful to predict physical activity behavior among the Iranian female adolescents. Information related to the predictors of physical activity behavior will help researchers plan more tailored culturally relevant health promotion interventions for this population.

Life table studies were conducted in the laboratory for the eulophid gregarious pupal parasitoid, Tetrastichus sp., on Hyphantria cunea Drury at a constant temperature of 28.2$\pm$2$^{\circ}C$, 50-60% RH to evaluate their impact on the host and their potential biological control. Development of immature stage took 20.1$\pm$2.7 d: adult females lived for 23.2$\pm$2.2 (range, 16-27)d and produced a mean of 53.6$\pm$26.6 adult progeny per female, with a sex ratio of 1: 9.5 (M:F). The intrinsic rate of natural increase (r$_{m}$) was 0.178/ female/day; the net reproductive rate (R$_{o}$), 46.74; the capacity for increase (r$_{c}$) 0.177; the finite rate of increase (λ) 1.19/female/day; thus each female contributed 46.74 individuals to the population in a mean generation time of 21.6 d. Biological factors in determining the life history trait variation of the parasitoid were discussed.d.d.d.
