Purpose: This study evaluated the validity and reliability of Shively and colleagues' self-efficacy for HIV disease management skills (HIV-SE) among Korean participants. Methods: The original HIV-SE questionnaire, comprising 34 items, was translated into Korean using a translation and back-translation process. To enhance clarity and eliminate redundancy, the author and expert committee engaged in multiple discussions and integrated two items with similar meanings into a single item. Further, four HIV nurse experts tested content validity. Survey data were collected from 227 individuals diagnosed with HIV from five Korean hospitals. Construct validity was verified through confirmatory factor analysis. Criterion validity was evaluated using Pearson's correlation coefficients with the new general self-efficacy scale. Internal consistency reliability and test-retest were examined for reliability. Results: The Korean version of HIV-SE (K-HIV-SE) comprises 33 items across six domains: "managing depression/mood," "managing medications," "managing symptoms," "communicating with a healthcare provider," "getting support/help," and "managing fatigue." The fitness of the modified model was acceptable (minimum value of the discrepancy function/degree of freedom = 2.49, root mean square error of approximation = .08, goodness-of-fit index = .76, adjusted goodness-of-fit index = .71, Tucker-Lewis index = .84, and comparative fit index = .86). The internal consistency reliability (Cronbach's α = .91) and test-retest reliability (intraclass correlation coefficient = .73) were good. The criterion validity of the K-HIV-SE was .59 (p < .001). Conclusion: This study suggests that the K-HIV-SE is useful for efficiently assessing self-efficacy for HIV disease management.

The purpose of this study is to explore the influence of the changed employment environment in full-time cooks at deluxe hotels on job insecurity and career commitment. Based on total 389 hotel cooks obtained from an empirical research, this study reviewed the reliability and fitness of a research model and verified total 2 hypotheses with the Amos program. The hypothesized relationships of the model were tested using a structural equation model(SEM). The SEM results show that layoff(${\beta}$=0.326), an organization structure(${\beta}$=0.237), irregular workers(${\beta}$=0.200) among changed employment environment have a significantly positive effect on job insecurity. Also, job insecurity has a significantly positive effect on career commitment. Accordingly, the changed employment environment in workers at deluxe hotels causes job insecurity, making them try harder to stay in an organization. Therefore, motivation is needed for employees' career commitment because the better job insecurity is managed, the more career commitment they have.

Purpose: The purpose of this study was to analyze factors influencing eating problems among young female adults. Methods: Participants were 193 young female adults aged 19 ~ 29 years who were recruited in August 2017. Four variables related to eating problems in young female adults, including body image dissatisfaction, self-esteem, trait anger, and depression, were measured using reliable instruments. Data were analyzed using the SPSS/WIN 21.0 program and Amos 24.0 for descriptive statistics, Pearson correlation coefficients, and path analysis. Results: The mean for eating problems in young female adults was 8.99, and 9.8% of subjects were classified as high risk with eating problems. Modified model demonstrated good model fit (${\chi}^2$/df 0.47, GFI 0.99, AGFI 0.99, NFI 0.99, SRMR 0.022, RMSEA 0.001). Path analysis showed that body image dissatisfaction had the greatest direct effect on eating problems. Depression did not have a direct effect on eating problems, whereas it had indirect effects on eating problems through body image dissatisfaction as the mediating factor. Self-esteem had direct effects on depression and indirect effects on eating problems through depression and body image dissatisfaction as mediating factors. Trait anger had direct effects on depression and body image dissatisfaction and indirect effects on eating problems through depression and body image dissatisfaction as mediating factors. These factors accounted for 46% of the total variance, and the fit indices of the model satisfied the criteria of fitness. Conclusion: The results of this study reveal the important role of body dissatisfaction and psychological factors such as self-esteem, trait anger, and depression on eating problems. These factors influencing eating problems should be considered when developing programs to improve eating problems in young female adults.

The purpose of this study was to examine the influence of parent's accomplishment pressure and career guidance on children's career development. The subjects in this study were 59 six-graders in an elementary school. Added to this, this study was to understand the course of elementary school children's career development. For the study, research questions on influence of parent's accomplishment pressure and career guidance on children's career development were set up. The study showed three findings. First, there was significant correlations between parent's accomplishment pressure, and career guidance and children's career development. Parent's accomplishment pressure showed a positive correlation with career development and career guidance had a significant correlation with children's career development. The sub factors of career guidance, except for emotional support, were also significantly correlated with the sub factors of children's career development. Second, Parent's accomplishment pressure didn't show significant effect on fitness of career choice, sex-prejudice and pride, but showed significant effects on total career development, career directivity, career comprehension, self-comprehension and self- control. Third, parent's career guidance showed additional impact on children's career development. But emotional support, which is the sub-fact of career guidance, had no correlation with career development.

To assess the dormancy associated weedy risk of the F1 hybrid generated by hybridization between Brassica juncea (maternal) and Brassica napus (paternal), seed germination, dormancy and longevity were examined sequentially after seed harvest. The F1 hybrids exhibited the intermediate characteristics of their parents in seed germination and dormancy with relatively high dormancy rate of 41.1%. In summer, F1 hybrid seeds buried in the 3 cm soil exhibited greater viability (52.4%) than those in the soil surface with greater seed longevity (74.6%) than its maternal (63.3%) and paternal (33.7%) parents at 100 days of over-summering in soil. In winter, F1 seeds buried in the soil surface were more viable than those in the 3 cm soil with greater seed longevity (83.5%) than its maternal (39.0%) and paternal (71.7%) parents at 100 days of over-wintering in soil. Therefore, it is concluded that F1 hybrid resulted from gene flow from OSR to mustard has high seed dormancy and longevity during summer and winter, suggesting its weedy risk potential. Further studies are required to examine the reproductivity and fitness cost of F1 hybrid to make a clearer conclusion of its weedy risk.

Ciliates have the possibility of a new live food in marine finfish culture because of their wide range of body size, thin tell wall, show motility, and fast reproduction rate. In this research, six species of ciliates were isolated from south coast and salt pond in Korea. The fitness of these species as a live food was evaluated in terms of size, motility, suspensibility and cell density. As the result, Euplotes sp. (K-1) was found suitable to be a new live food which might substitute rotifers, Brachionus plintilis and B. rotundiformis in fish larvae culture. The modified $F{\emptyset}yn's$ Erdschreiberd media, MErds-2 with the addition of glycine, glucose and yeast extract increased six times higher growth rate of Euplotes sp. (K-1) than the basic F$\emptyset$yn's Erdschreiberd media. The optimum water temperature, pH and light intensity for this ciliates were $22.5^{\circ}C$, 8 and 2,000 lux, respectively, and its culture environmental range was relatively wide, On the other hand, this ciliate fed baker's yeast, Saccharomyces cererisiae grew up to 1,240 inds./mL with the inocula of 100 inds./mL within 7 days. The results of the study showed that Euplotes sp. (K-1) has a potential to be utilized as a new live food in fish larvae culture.
