This paper investigates the influence of industrial activity volatility and exchange rate volatility on import container volume of the Korea during the 1999:1- 2010:9. Conditional variance from the GARCH(1, 1) model is applied as the volatility. The Johansen multivariate cointegration method and the error correction (general-to-specific) method are applied to study the relationship between import volume and its determinants. The empirical results show that volatility has statistically significant negative effect on import volume.

In this paper, I propose some policy and theoretical implications by analyzing moderating effects of volunteering activity in the causal relationships between social welfare major choice and their job choice. For the purpose of the goal of this study, I surveyed 242 university students in 2~4 grades majoring social welfare in Gwangju and South and North Jeolla Province. Analysis results showed that the personal motive on choosing a major affects the occupational aptitude & interests and economic feasibility of career when they choose their jobs. However, the social motive didn't affect the occupational aptitude & interests and economic feasibility of career. It means that they didn't choose their majors considering their aptitude & interests, but chose them by following the advice of the surrounding people. Also, moderating effects of volunteering activity was not significant, which means that volunteering period and schedules are too short and tend to be operated as a mere formality. This study suggests the policy implications so that they have the correct major selection and career options based on the analysis results.

The energy of the building is influenced by the user 's activity due to the population, society, and economic characteristics of the building user. In order to obtain accurate energy information, the difference in the amount of energy consumption by the activities and characteristics of building users should be identified. The purpose of the study is to identify the difference in the amount of energy consumption by the user's activities in the same building, and to analyse the relationship between user's activities and demographic, social and economic characteristics. For research, energy simulation is performed based on actual user activity schedule. The results of the simulation were clustered by using K-Means clustering, a machine learning technique. As a result, four types of users were derived based on the amount of energy consumption. The more energy used in a cluster, the lower the user's income level and older. The longer a user's indoor activity times, the higher the energy use, and these activities relate to the user's characteristics. There is more than twice the difference between the group that uses the least energy consumption and the group that uses the most energy consumption.

The purpose of this study is to estimate and forecast the marine trading volumes based on the structural model. We employ GPH cointegration test since the structural model must be stationary to get the accurate predicted values. The empirical results show that our model is stationary. This paper also applies variance decompositions and impulse-response functions to the structural model composed of exchange rate, domestic industrial activity, and world business. The results indicate that while both loading and unloading volumes respond positively to the shocks in income and then decay very slowly, their responses are different to the shocks in exchange tate.

Many of the chiral NSAIDs are marketed as racemates. There is an increasing interest in developing the enantiomerically pure forms of the NSAIDs because the anti-inflammatory activity of NSAIDs have previously been shown to be largely sterospecific for the (S)-(＋)-enantiomer. Therefore, simple and economic preparative method to identify the (S)-(＋)-enantiomer of NSAIDs (aryl propionic acids) as diastereomeric solvation complex was developed using several chiral solvating agents by recrystallization of racemate and solvent fractionation.

Objectives: Physical activity provides economic benefits and contributes in improving health and quality of life. Opportunities for physical activity continue to decrease with the increasing prevalence of sedentary lifestyles. In various settings, there have been many efforts to enhance physical activity to prevent chronic disease for people of all ages. This study was performed to define competencies of physical activity specialists in health promotion and compare with those of health education specialists. Methods: The study employed official data and manuals of health promotion programs that have been published and uploaded on public websites. Results: Competencies for physical activity in health promotion included needs assessment, analysis of data and scientific information, planning and evaluation, developing strategies and materials, management, building healthy environment, research. To compare with the competency of health education specialists, competencies of physical activity were almost similar to that except the developing individual-based physical activity program in exercise science. Conclusions: Physical activity programs for health promotion should be planned and implemented throughout various health topics and in coordination with multiple sectors. To increase efficiency of the utilization of human resources in health promotion, health education specialists needs to participate in physical activity programs and would require empowerment in exercise science.

This research aims to look into correlation between Korea's childbirth promotion policy caused from women's maternity leave and economic activity. For the purpose, 300 surveys were distributed to mothers using postnatal care centers located in Seoul. Listed postnatal care centers such as Babe Glory, Shinsegae, Happy, Miznomall and out of 260, 222 surveys were selected for the research. Several advanced studies regarding child birth promotion policy backed up by current government and related domestic and overseas documents were used as reference. Decisive factors including social insurance, tax, cost for child birth and rearing service, social culture were derived as trait elements for child birth promotion. Mentioned factors along with economic activity by childbearing women were used when setting up the research model and hypothesis. Relation with material leave was employed as parameter for this study of which purpose lies in empirical analysis and investigation.

This study classified social stratum variables of adults in their 20s to 50s by subjective and objective measurements and classified leisure activities into groups to examine the conspicuous consumption of leisure apparel. A total of 365 adults in their 20s to 50s living in Daegu and the Kyungbuk area were selected considering their jobs and residences. SPSS PC+ 20.0 was used to analyze the data with frequency analysis, factor analysis, reliability examination, cluster analysis, ANOVA, Duncan-test, Scheffe-test, and ${\chi}^2-test$. The results of this study are shown as follows. First, 'Jogging/Walking' was found to be the most favorable activity in the examination of leisure sports activities among the participants and showed a difference in gender. Second, leisure activities were pastime-culture activity, sports activities, static activity, volunteering, and relaxing, and these activities were grouped into non-participant, active and passive leisure activities. Conspicuous consumption of leisure apparel was classified into personality oriented, luxury goods-oriented, and other people-oriented. Third, there was a significant difference in the sub-factors of the conspicuous consumption of leisure apparel (personality oriented, luxury goods-oriented, other people-oriented) according to the sub-factors of subjective stratum(economic power, social position, level of consumption, cultural level and overall stratum consciousness). Fourth, there was significance in the objective social stratum variable by the types of leisure activities. Significant differences were found in personality orientation, luxury goods-oriented, and other people-oriented in conspicuous consumption of leisure apparel by the types of leisure activities. Finally, there were significant differences in economic power, level of consumption, cultural level of subjective social stratum by gender, sports activities and volunteering in leisure activities, as well as other people-oriented conspicuous consumption of leisure apparel. This study also found significant differences in economic power, level of consumption and cultural level of social stratum by age, as well as other people-oriented conspicuous consumption of leisure apparel.
