RUSLE(Revised Universal Soil Loss Equation) has been widely used to estimate the soil loss amount of watersheds from rainfall erosivity, soil erodibility, topographic features and cropping management condition. Rainfall erosivity is the most dominant and sensitive factor among these so that the determination of reliable rainfall erosivity is essential to estimate the soil loss of watershed. Since there has been no criterion to determine the rainfall erosivity in Korea, the empirical values, determined from the relation between the annual average rainfall and erosivity or suggested by TBR(Transport Research Board), have been used for designing the erosion control structure and controlling the soil erosion for watersheds. In this study, the procedure for estimating the rainfall erosivity using frequency analysis is proposed. The most fitted distribution function, with calculated rainfall erosivities with various frequencies and durations, has been also selected. The suggested procedure can be used to estimate the optimal value of rainfall erosivity for RUSLE in order to design soil erosion structures and control the soil erosion in watersheds effectively.

Despite the early success story, the pan-industry diffusion of big data has been slow mostly due to lack of confidence of the value creation and privacy-related concerns. The problem leads us to the need to a stakeholder analysis on the adoption process of big data. The present study combines technology acceptance model, task-technology fit theory, and privacy calculus theory to integrate the positive and negative factors on the big data adoption. The empirical analysis was performed based on the survey from the current and potential big data users. Results revealed perceived usefulness, task-technology fit, and privacy concern are significant antecedents to the intention to use big data. Furthermore, there are significant differences in the perceptions of each constructs among groups divided by the types of big data use, with several exceptions. And the control effect was found in the magnitude of the relation between independent variables and dependent variable. The theoretical and politic implications of the analysis are discussed as to the promotion of big data industry.

Determining the coefficient of weathering(CW) for stone heritage plays very important role in investigation and conservation plan. In most case, CW is obtained from the empirical relation, which use the difference between sonic velocities of fresh and weathered rocks. In this paper, we measured sonic velocities for the samples from Iksan, Geochang, Wonju, Goesan and Chungju of which our stone heritages are made. We first investigate the uncertainty of velocity by portable measurement by comparing it to lab measurement. There were small difference, but we conclude that the difference is not major. However, the velocity of fresh rock differs significantly among samples: ranging from 3200 to 4400m/s. This cause a lot of error in CW estimation if we use typical fresh rock velocity as of 5000m/s. Thus accurate measurement of the velocity of fresh rock is crucial to CW estimation.

This study examined the cost consciousness, food materials satisfaction, job satisfaction, and degree of food materials management of chefs, as a means to increase food materials management efficiency in hotel restaurants and to make suggestions, for efficiently reducing food material costs, Chefs from eleven 5-star hotels and one exceptional-grade restaurant in Seoul were asked to fill out a questionnaire for sampling. A total of 350 questionnaires were distributed and 334 were returned (95.4% return rate). The characteristics of the respondents were examined by population statistics analysis, and the chefs' cost consciousness, food materials satisfaction, and job satisfaction were examined by descriptive statistics after reliability and propriety analyses. The degree of cost consciousness in the respondents was very high and this degree of consciousness proved to have a partially significant impact on the degree of food materials management. That is when the chefs were more conscious about cost, the degree of food materials management was high. This implies that food materials satisfaction can be enhanced by enhancing the degree of food materials management. Job satisfaction also had a partially significant, influence on the degree of food materials management. Therefore, it is necessary to maintain consistency in the quality and inspection of food materials, provide related information, enhance the satisfaction level for standards of food materials and improve policies for welfare and career after retirement in order to enhance the job satisfaction of chefs and subsequently reduce costs in relation to the level of food materials management.

Natural Medicine is a medical system that tries to find the cause and cure of the disease in the nature emphasizing on natural healing power of human body. The most important value of traditional medicine in east Asia lies on the fact that this medicine is a medical culture and natural medicine that was selected by instinct and human nature reflecting the best possible remedy by the wisdom of evolution, and views the living phenomenon based on relation and circulation. This medicine is a natural medicine that tries to recover and promote the natural healing power by vitality and is a system that cumulates various empirical information about unique and complicated life phenomenon as a legacy of evolution in the body and the disease. The understanding of variation and adaptation of human species should be based on thorough knowledge of origin, instinct and nature of human as well as knowledge of survival and adaptation of human and environment based on evolution. And through this insight, the prevention and treatment of modern diseases should be developed. In this regards, traditional medicine in east Asia should be highlighted again as a study on adaptation and harmony of penetrating the cultural history of mind which has led the history of biological body and change of society and culture, and the repository of practical wisdom and knowledge.

The purpose of this study is to analyze the impact of cash holdings on internationalization of listed manufacturing firms. We explore moderating effect of managerial ownership between cash holdings and internationalization of firms. We analysed cross-sectional data of 645 listed companies from 2000 to 2013 using the fixed effects estimation. Empirical results showed that the there was a positive significant relation between cash holdings and internationalization of firms This study also found that managerial ownership have a significant negative moderating effects in the pathway between cash holdings and internationalization Cash liquidities can be rapidly induced internationalization. Managerial ownership increase agency cost, therefore, it might have a negative effects on internationalization These results suggest that agency cost with cash holdings is very important for cash management.

Prior literature shows that audit market concentration which is measured as the Herfindahl index is negatively associated with audit quality in Korea. This study analyzes whether characteristics of an audit committee have effect on the relation between audit market concentration and audit quality. This is because it is expected that effective audit committees restrict the tendency of dominant auditors to neglect their duties. The empirical results of this study using the sample firms having an audit committee listed in the Korea Composite Stock Price Index market for 2006-2015 are summarized as follows. First, consistent with prior research, audit quality decreases as audit market concentration increases. However, audit quality is not lowered as audit market concentration rises only when the audit committee has financial expertise among representative characteristics of an audit committee - independence, financial expertise, and activity. This research finds contributions in that it explores the effect of audit committee characteristics on audit quality in consideration of audit market concentration and utilizes the differential types of the characteristics of an audit committee at the same time.

This study starts from the research question that "Why some companies decide to keep working in partnership even when they are not satisfied with the partner companies simply because they are old business partners." The authors try to find the answer in terms of customer value considering the phases of B2B transaction spectrum: transaction value, relationship value and appraisal value implementing empirical research. The result shows that the intension to retain the relation with an existing partner is formed by the trade-off between the benefit and cost of both contract value and relationship value and not the sole value was dominant. The unique point of the study is that current study is considering these two factors as dependent variables which affect the relationship continuity which is not the case in existing researches.
