This study is to analyze the effects of changing pattern of climate vaariables on total factor productivity of Korea manufacture industry. Changes in temperature, rainfalls and humidity which are the representative climate variables are used as main factors. Not only average values of the variables but those highest values are used as independent variables in the model, in order to consider the characteristic pattern of recent climate change, the high volatilities. The OLS results are unlike to previous literature that temperature and humidity had no significant impact on manufacturing productivity. An increase in the amount of precipitation was analyzed that impact negatively impacted. The analysis of panel data showed that temperatures and precipitation all that does not significantly affect the manufacturing. While the increase of the average humidity is shown to increase the total productivity of manufacture industry. In Korea, adaptation capability is important in determining the effects of climate change on productivity of manufacture industry.

This study deals with the psycho-social development of children raised by disabled parents. In particular, we are willing to examine the influence of parental factors such as social engagement and future forecast on the change of children's psycho-social development. Using the three waves of Korean Welfare Panel Study data, these predictors were examined through the Latent Growth Curve Modeling. The result shows that parent's disability has a negative influence on their children's psycho-social development. However, similar to the findings of the previous studies, the degree of this influence tends to be decreased as children grow up. Lastly, two parental factors have a direct influence on the psychological development of children. Furthermore, parent's social engagement has an indirect influence on the change of sociality of children through the psychological change of them. This result means that we should encourage disabled parents to participate actively in social activities and think positively about their future.

The purpose of this study is to verify the causal relationship between social withdrawal and peer alienation among Korean children. The survey study participants were 2,110 children in 2nd, 3rd, 4th, and 5th grades. The 5-year longitudinal data (Korean Child and Youth Panel Survey; KCYPS) of 1st grade elementary school student cohort was used. Latent Growth Modeling was applied to analyze the causality over time of social withdrawal and peer isolation. The results revealed that the trajectories of children's social withdrawal decreased over time. Children's social withdrawal showed significant individual differences in terms of initial value and rates of change. The initial value and slope of children's social withdrawal had an effect on the peer alienation in the 3rd grade; however, there was no significant effect on the peer alienation in the 5th grade.

The purpose of this study was to assess the impact of childbirth on socioeconomic status changes of women. Data were collected from Korean Health Panel (2008-2015). A difference-in-differences model with propensity score matching was applied to assess the impact of childbirth on socioeconomic status changes. As a result, variables showing significant differences in the interaction terms indicating the impact of birth were the savings, economic activity, and occupational status. The impact of birth were significant in decreasing the amount of savings and negatively affecting women's economic activities, but in increasing the probability of full-time and regular employees in occupational status. Childbirth appears to have a negative impact on the home economics and socioeconomic status of women. The belief that home economies can be stabilized even after childbirth should be established, and a long-term and sustained support plan should be set up to realize this belief.

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.
