The contents of this work embody three chapters, which are an investigation on advanced research, an analysis of SOGO-SHOSYA business outcome, logistics function in its energy business field, Research method are used by statistical analysis and organizational structure analysis as well as case study. We will search for the reason that the energy business has worked well lately. There are actively securing interests of energy exploitation and longer-term investment to affiliated companies, building supply chain system with internal and external businesses. Especially, we will account for the logistics role of SOGO-SHOSYA that has newly understood the international logistics function in energy business field. SOGO-SHOSYA has coordinated organizationally from upstream to downstream in energy business, is showing its abilities in midstream related features that involve investor, organizer and analyst.

Similarity rule in order to predict the field settlement and consolidation time from oedometer test is not clear because of the thickness, loading time, rate of loading increase, dependence on strain inherent of clay. To investigate the one-dimensional consolidation tests with permeability tests varied loading period and specimen thickness were carried out the application of similarity rule. Main conclusions are 1) f(=1+e)-logk line is a unique property of the soil, 2) $c_{\nu}$, k need no correction, 3)similarity rule is depends on the positions of f-logp line and primary consolidation line.

This study presented a theoretical research system about the impact of boss' transformational leadership that is recognized by super luxury hotel chefs on their job satisfaction and performance, and on the basis of this theoretical background, the model was derived and the hypothesis was confirmed by empirical research. A frequency analysis was conducted to determine the general characteristics of the 245 samples collected in this study, an exploratory factor analysis for the verification of the validity of boss' transformational leadership, employees' job satisfaction and job performance, and 'Cronbach's a' was used for the verification of reliability. In addition, a canonical correlation analysis was used to determine the relationship between transformational leadership, job satisfaction and job performance, and the influencing relations of variables were verified by running a multiple regression analysis through SPSS ver 18.0 statistical package in order to verify this research model and hypothesis. The results of this study can be summarized as follows: First, it was shown that the transformational leadership charisma (p<0.01) and only the individual concern (p<0.1) had a positive influence on job satisfaction. Second, as a result of understanding the impact of the transformational leadership on the job performance through a regression coefficient, it was shown that only boss' intellectual stimulation had an impact on the chef's job performance (p<0.005). Through the results of an empirical analysis that boss' transformational leadership had a correlation and a significant impact on job satisfaction and job performance, the effort of providing the systematic support and motivational aspects of supporting environment will be needed.

The purpose of this study was to examine the relationships between emotional intelligence and job performance. Also, the study explore the effects of self-efficacy as a mediating variable and person-supervisor fit as a moderating variable on the mentioned relationships. In order to verify the assumptions related to this research, a survey of 173 sales representatives working in various organizations was conducted. Survey results supported the assumption that higher emotional intelligence resulted in higher job performance. And another assumption that job performance could be predicted more precisely through mediating effect of self-efficacy. Finally, results revealed that the relationships between emotional intelligence and self-efficacy became stronger when the scores of person-supervisor fit were higher. Theoretical and practical implication were reviewed and limitations of the study and suggestions for future research were discussed.

The established hypotheses related to transformational leadership, organizational commitment, and emotional intelligence were verified by the hierarchical regression analysis using SPSS. The result of this research are as followers : First, the hierarchical regression analysis revealed that moderation term was significant(${\beta}$=0.146, p<.01). The interaction term for charisma and emotional intelligence had a significant and positive relationship with organizational commitment. Second, the hierarchical regression analysis revealed that moderation term was insignificant(${\beta}$=2.295, p<.05) The interaction term for inspirational motivation and emotional intelligence had a significant and positive relationship with organizational commitment. Third, the hierarchical regression analysis revealed that moderation term was significant(${\beta}$=0.200, p<.001). The interaction term for intellectual stimulation and emotional intelligence had a significant and positive relationship with organizational commitment. Fourth, the hierarchical regression analysis revealed that moderation term was significant(${\beta}$=2.213, p<.01).

This research was carried out to decide both in the field and the laboratory the similarity between the erosion and the accretion in the change of the beach profile. The results obtained were as follows: (1) It was impossible to decide only by C value the similarity between the erosion and the accretion of the actual beach by application of Horikawa's theory. (2) It was difficult to decide the similarity only by values of $H_//L_0$ formula. (3) Observation of dimensionless value of $H_//L_0$ and C, $H_//L_0$ and $L_{sr}$ in the field and the laboratory showed that there was a similarity between the erosion and the accretion which set in at 0.024 of $H_//L_0$. (4) The Knowlege of the wave steepness would help to discriminate the erosion and the accretion.
