This study focused on the importance of job position as a role model for female career adaptation. To do this, we used the KWMP data to conduct a Multinomial logit analysis to examine the influence factors of the tenure women managers. As a result, first, section chief position showed a low level of life satisfaction and showed difficulty of beginner's manager. Second, it is predicted that the position of the Deputy Head of Department will establish the identity of work as an intermediate manager. Third, head of department Director showed a high age, target status, possibility of achieving the target, and duration of the next job. Fourth, executive level has the least average experience of discrimination on monthly average wage. It was suggested that it is important to develop individual career by recognizing that the organizational atmosphere and personnel management are lower than those of the other positions. It was found that age, organizational atmosphere and personnel management, goal status, possibility of achieving goals, next job tenure period, monthly average wage, welfare, and life satisfaction factors were the most influential factors in women career adjustment. Finally, implications and limitations were discussed based on the results of this study.

To understand physical phenomena of ship maneuvering deeply, a numerical study based on computational fluid dynamics is required. A computational method that can simulate the interaction between the ship hull, propeller, and rudder will provide informative local flows during ship maneuvering tests. The analysis of local flows can be applied to improve a physical model of ship maneuvering that has been widely used in maneuvering simulations. In this study, the numerical program named as WAVIS that has been developed for ship resistance and propulsion problems is extended to simulate ship maneuvering by free-running tests. The six degree-of-freedom of ship motion is implemented based on Euler angles and the overset technique is applied to treat the moving grid of ship hull and rudder. The propulsion force due to a propeller is calculated by a panel method that is based on the lifting-surface theory. The newly extended code is applied to simulate turning and zig-zag tests of KCS and the comparison with the available experimental data has been made.

The study looked into the effect of internet utilization (utilization frequency and utilization ability in internet) on the life satisfaction level for the elderly in depth. In order to verify the correlation of two variables, a mediating model structured by ego integrity was used which gave out the Seoul welfare panel data created by Seoul welfare foundation in 2010. The total sample size was a group of 1862 elders aged over 60. When it came to our research methods, structured equation analysis was applied to verify the mediating effect and theoretical background. The findings are as follows: First, elderly's utilization frequency in internet is not an influencing factor to life satisfaction and elderly's utilization ability in internet is an influencing factor to life satisfaction. Second, the level of social activity did function as partial mediator on relationship between elderly's utilization ability in internet and life satisfaction. This study indicates theoretical and practical interventions to promote elderly's utilization in internet.

The purpose of this study was to investigate the relationship between child maltreatment, protective factors, and resilience in elementary school students. It was especially focused on what direct effect of the risk factor(child maltreatment) and protective factors to child resilience, and how protective factors affect the resilience of maltreated child. In the concrete, this study intended to find out whether protective factors mediate between child maltreatment and resilience. This study based on data from the first wave of 'Korean Youth Panel Survey(KYPS)' and subjects consisted of 2,844 4th grade elementary school students. In addition, to test the proposed models, the Mplus-structural equation modeling-was used. The major findings are as follows: First, when child maltreatment increased, resilience decreased. Second, when protective factors increased, resilience increased. Third, protective factors act as buffers against the negative effects of child maltreatment on resilience by mediation. Results indicated that child maltreatment related negatively to resilience and protective factors related positively to resilience. In addition, a mediational model in which protective factors mediates child maltreatment and resilience was supported. In conclusion, various theoretical and practical implications for social work practice focusing on the maltreated children were discussed.

Objectives: The purpose of this study was aimed to examine the effect of self-esteem on life satisfaction and happiness among adolescents, and to verify moderated mediation of peer relations mediated by altruism and self-regulation. Method: The study referred to the 2015 Annual Report of the Korean Children and Youth Panel Survey. More precisely, report on the fourth year research process of the study cohort comprising 2,091 subjects was used to verify the research model. Overall data were analyzed by using SPSS 18.0 program and specifically, moderated mediation were verified by using SPSS Macro, as suggested by Preacher, etc. (2008). Results: As a result, firstly, the peer relations mediated the relationship between life satisfaction and self-esteem among adolescents. Secondly, altruism and self-regulation had moderated mediation effects between self-esteem and peer relations among adolescents. Conclusion: These results suggest that self-esteem affects on life satisfaction and happiness by mediation of peer relations among adolescents and altruism and self-regulation agent is applied positive adjustment to further promote the peer relations and increase life satisfaction among adolescents. Through these study results, the implications for counseling and suggestions for future research were discussed.

Purpose - The purpose of this study is to specify the relationship between demographic cohesion and firm performance by examining the roles of HR practices, such as job rotation and flexible work arrangement. Design/methodology/approach - This study samples 1,093 firms in Korea and collects their data between 2007 and 2017 from Workplace Panel Survey, a database from Korea Labor Institute. The demographic cohesion is measured using the Herphindal-Hershman index and the firm performance is measured with net incomes. This study employs a fixed-effects model for the estimation of firm performance with respect to demographic cohesion, job rotation, and flexible work arrangement. Findings - There is a positive relationship between demographic cohesion and net incomes. And the relationship is positively moderated by job rotation. However, flexible work arrangement shows a mixed moderation. Research implications or Originality - Differentiated from the studies on demographic diversity, this study shows that demographic cohesion has a mixed impact on firm performance. While demographic cohesion can improve firm performance through trust building, in-group favoritism, and collective identity it entails internal conflicts. However the link between demographic cohesion and firm performance is moderated by job rotation and flexible work arrangement. While there is a positive moderation of job rotation, there is a negative moderation of flexible work arrangement.

Using the 1st to 13th rounds of occupational history data of the Korea Employment Information Service's Youth Panel (YP2007), this study explores the trends and characteristics of the youth labor market in Seoul. We further empirically investigated the job duration and wage determinants of youth employed in Seoul. The results confirm that workers who have a higher income and a higher consistency with their majors are less likely to leave. In addition, we find that workers in full-time, householders, or labor unions have a higher income if they are men and work in large companies. In particular, compared to the reference group (appropriate academic background, appropriate skill), mismatches in the lack of education and skill showed a wage increase effect of 4.9% and 5.5%, respectively. For the major consistency, the wage of the matched major group is 3.8% higher than the non-matched major group.

This study examines the housing-related characteristics of unmarried youth using occupational history data from the 10th-14th (2016-2020) youth panel (YP2007) of the Korea Employment Information Service, and the characteristics of housing and employment. Their effect on marriage intention was empirically analyzed. The results of the analysis show that highly educated people, high-wage workers, household heads or economically independent young people, and young people in good financial conditions have a high willingness to marry. Their economic conditions are very important factors. Among the young employed who have become economically independent from their parents, full-time permanent workers, workers at large corporations, and highly waged youth showed a strong desire to get married. On the contrary, young people who are insecure temporary/daily workers, workers at small firms, and low-wage workers show a low willingness to marry. In conclusion, the results imply that young people who are in a vulnerable state in the labor market are giving up or delaying their marriage. Therefore, it is necessary to enhance policies to provide better employment opportunities for youth and, simultaneously, revamp the policy measures to enhance housing conditions.
