This paper analyzes the characteristics of change in economic indicators logistics business performance indicators in Japan over the past decade. We compare the differences in management performance of groups related to logistics business strategy. This is because we want to show that the logistics business strategy is reflected in the management performance. Research methods include correlation analysis, crossover analysis, and variance analysis. The main results are as follows. First, logistic companies' sales are highly correlated with economic indicators such as GDP, trade value, and stock price. Second, there is a correlation between the business sectors and the proportion of tangible assets. It is understood that different business strategies are appropriate for each industry and each period. Third, the effects of business strategy variables on business performance variables were significant. In particular, the interaction effect of three variables showed a difference in the effect on the yield. The results of this study provide a better understanding of how logistics companies achieve a high performance in the changing economic environment over the past decade.

The aim of this paper was to develop a scale for measuring gender identity among sports participants (114 male, 193 female). Gender similarities and latent mean analysis was used to validate the gender identity measurement method. Data processing was carried out by way of frequency analysis, exploratory and confirmatory factor analysis, reliability, correlation, normal distribution of questions, and latent mean analysis using SPSS 18.0 and AMOS 18.0. The results of this study were as follows: First, the equivalence had revealed the configurable, metric, and scalar invariance of the scale that can be used in multi-groups in the same way. Second, women had a more open inclination than men when it came to participating in sports activities (p<.001). Third, women participating in sports activities tended to be more conservative than men (p<.001). Fourth, women who participated in sports activities showed a higher subjective tendency than men (p<.001). Fifth, there was no statistical difference in the outward tendency when participating in sports activities (p<.05). The results of this study suggest that gender identity among sports participants is not influenced by the changing times and the advancement of women in society.

In school mathematics, activities to make particular convex polygons by attaching edgewise some pieces of tangram are introduced. This paper focus on deepening these activities. In this paper, by using Pick's Theorem and 和 草's method, all the convex polygons by attaching edgewise seven pieces of tangram, Sei Shonagon(淸少納言)'s tangram, and Pythagoras puzzle are found out respectively. By using Pick's Theorem to the square seven-piece puzzles satisfying conditions of the length of edge, it is showed that the number of convex polygons by attaching edgewise seven pieces of them can not exceed 20. And same result is obtained by generalizing 和 草's method. The number of convex polygons by attaching edgewise seven pieces of tangram, Sei Shonagon's tangram, and Pythagoras puzzle are 13, 16, and 12 respectively.

This study examines how the family background and educational aspiration of adolescents affect the usage pattern of internet among adolescents. Recently, the focus of studies on digital divides shifts from the gap in the access to the internet to the difference in usage pattern of internet. Building on these studies, this study deals with the concerns that the difference in usage pattern of internet among adolescents potentially lead to the reproduction of social inequality across the generations. The analysis of the Korean Youth Panel Study reveals that the higher educational attainment and higher income level of parents, the children tend to spend more time in searching with the internet and spend less time in doing the internet game. The level of educational aspiration exerts similar effects on internet use of adolescents. The results also show that the effects of educational apsiration is larger among older adolescents. The implications and limitations of this study are discussed.

With regard to gaining employment for specialized high school graduates, what are the significant factors? Along with specialized high school's employment support, facility and subject support, vocational ability support, career guidance, and employment support are implemented at school. At the same time, individuals are learning career preparation behavior and job search behavior. Those factors influence the career maturity. Therefore, a question is, "Do they finally affect employment?" The independent variables were composed of satisfaction on school support, such as facility and subject support, career preparation behavior at home, pre-job search behavior, and career maturity. A structural equation was created and an analysis was conducted. As a result of the analysis, the satisfaction on school support has significant impacts on career maturity and career preparation behavior at home and influences on employment directly or indirectly. The career preparation behavior at home not only has a direct impact on employment, but also increases the pre- job search behavior and career maturity. In particular, it was confirmed that the career preparation behavior at home is the main factor to increase employment via the pre-job search behavior. Considering the effects among the factors in gender, the satisfaction on school support directly increases employment, particularly for women. Therefore, high-quality school support programs should be enhanced, focusing on employment support programs for women. In addition, as satisfaction on school support increases, women are more likely to undergo career preparation behavior at home. This suggests that the career preparation behavior for females, such as conversation about career, is a critical factor to increasing employment unlike males. Therefore, support programs for women that is aimed at parents should be developed.

Korean Youth are facing diverse problems. For-instance Korean youth are even called '7 given-up generation' which indicates that they gave up marriage, giving birth, social relationship, housing, dream and the hope. From this point, the study concludes that the influential factors of the alcohol problems of youth should be studied based on the eco social perspectives. And it adopted data-mining methods, using SAS-Enterprise Miner for the analysis, targeting 2538 youths. Specifically, the study analyzed and chose the most predictable model using decision tree analysis, artificial neural network and logistic analysis. As the result, the study found that gender, age, smoking, spouse, family-number, jobsearching and economic participation are statistically significant determinants of alcohol problems of youth. Precisely, those who are male, younger, have the spouse, have less family number, searching jobs, have more income and have the job were more prone to have the alcohol problems. Based on the result, this study proposed the addiction problems targeting youth and etc. and expect to have the contribution on implementing procedures for the alcohol problems.
