The hardness and physical properties of soils were measured in hiking trails of Mt. Halla and Darangshiorum in Jeju Island to examine the characteristics and formative factors of an aquiclude induced by human trampling. The soil hardness, being generally the highest on trails, decreases outward and shows the lowest on adjacent slopes in a natural condition. The bulk density and solid phase also demonstrates a similar tendency, then implying that the aquiclude occurs in the central part of trails. Although the formation of a hard layer in trails is fundamentally attributed to human trampling, the environmental factors such as landform, lithology, soil and vegetation play a role in the occurrence of the aquiclude. Soil compaction varies with the gradient and location of trails which affects a transport and deposition of soil particles to produce a hard layer. Soil compaction also depends on the physical properties of soils including the soil texture largely affected by lithology. Vegetation is not directly related with the formation of a hard layer, but affects its dimensions through an enlargement rate of bare trails depending on the response and resistance of plants to human trampling.

The smart phone is globally spreading, since the Apple rolled out the iPhone. Thereafter the smart phone ecosystem is being reorganized and strongly governed by the Apple and Google, the mobile OS providers. And the mobile carriers are pushed out of the ecosystem with the progress of the dump pipe. Even though the South Korea has the strong position as a global leader in ICT industries, it have not properly coped with this new situation and is falling to the follower in the smart phone era. Therefore it should try to take advantage of the current of the times like its component industry who already enjoys the fruit. This paper reveals the new structure of the ecosystem along its value chain with the digital open markets, OS providers, phone manufacturers, and mobile carriers. And it shows the economic spillover effects using the input-output analysis. Consequently, this paper will provide the valuable implications to companies in setting up the efficient strategies and the regulator in promoting the ICT industry.

The miraculous growth of Korean economy and its business corporations during 1960' s and 1970's are mainly due to the government leadership and its market intervention. We can find the reasons why the government initiated economic growth plan was so successful in Korea in its efficient bureaucratic government system and fair discipline to the corporations based on its contribution to the economy. During 1960's, the primary factors for the growth of business entities and the formation of business groups were the financial special favor, the preferential treatment in the new industry entrance and the merge & acquisition, lavish export incentives from the government, and the export explosion to Vietnam. During 1970's, the substantial deduction of corporations' private debt, enormous support in heavy industry investment, special benefits to general trading companies by the government, and the construction export to the Middle-East were the main causes of the business growth and the business groups formation. Also, the economic rent for the big companies had still been effective since 1960's. However, the preferential benefit to the big companies made them to diversify into the unrelated business ares and to be in very vulnerable financial position. The governmental support brought about the monopoly as well.

Previous research about SNS users' intention was mainly focused on revisit intention, while this study reaches a research conclusion by considering both revisit and switching intention. According to the research result, (1) social interaction and SNS addiction influence other precedential factors; (2) enjoyment and usefulness increase SNS users' revisit intention; (3) SNS users would not consider switching to another SNS even they have negative opinions about their current SNS. This research result implies that, for SNS enterprises to dominate market, it is required to provide services so that SNS users can actively participate on social interaction activities, and a strategy is necessary to attract and turn SNS users with negative opinions into active participants.

We propose the statistical modeling and empirical results that can be utilized to identify and interpret the structural factors of international arms exports in recent years. The building blocks of research comprise the following questions; which would be the explanatory variables for the changing trend of international arms exports, whether the statistical significance can be verified on those variables and how those are interpreted for the future policy making purpose. We use the dataset of top 40 countries from SIPRI's Arms Transfers Database and analyze several regression models which consist of explanatory variables derived from research hypotheses. The most noticeable result is that the national fiscal reserve is shown to have consistent influence on the arms exports changes. UN security council members' group also has dominant power to make a formation of arms exports market block. Furthermore, gross domestic product and net exports volume in the national economy would seem to be related to changes of international arms exports in post-2000 period as well.

The data from the fertilizer experiments from 1974 to 1981 were compiled and interpretation were made as to the effect of soil fertility on the quality and yield of cured tobacco supplied with conventional rate (10-15-20, 125Kg/10a). With high soil fertility, the yield of tobacco with conventional rate increased in quadratic curve, but the quality decreased. The results indicate that soil which can produce 81Kg/10a of flue-cured tobacco without fertilizer application would be optimum to the 125Kg/10a fertilizer application. On the other hand, Flue-cured tobacco yields of non-fertilizer plot are supposed to be fertility of determining the application rate which can be recommended.

This research is an empirical research that surveys the influence factors of franchisee's compliance and precedence, which have a direct effect on the success of franchisor, from the view of relation exchange theory. The results herein show that the trust of franchisees towards franchisor has a complete mediating effect between conflict and compliance. This means that in a franchise system, it is important to build trust in order to successfully manage franchisees. Trust built between franchisor and the franchisee has a dominating effect based on relationship even on domains not specified on the contract. Also, it is very important in that it decreases frequently occurring conflicts caused by disagreement of interests and unfair relationship of power, and effectuates compliance of franchisees. Such result is a meaningful theoretical and practical contribution in that it has for the first time domestically investigated the mechanism of relationship leading from conflict and trust to compliance of franchisees by methods of theoretical discussion and empirical analysis.

This paper intends to examine the antecedents to the ex-post supply price cut which is typical retailer's unfair trade practices from three perspectives such as market power, efficiency, and retailer's tendency. For the empirical research, we analyzed manufacturer's 79 key account managers who have traded with domestic discount stores. As a result, the harder a retailer tries to increase sales and margin simultaneously, the more the retailer tends to use the ex-post supply price cut against manufacturers. In addition, the most frequent pattern of ex-post supply price cut occurs after retailer's discount at discretion. Finally, we suggest this research's implications, limitations of this research with future research directions.

Heavy metals (Fe, Mn, Cr, Co, Cu, Ni, Zn, Pb) were determined in ninety-one surface sediments collected from Kwangyang Bay, south coast of Korea. The data show that the Fe, Cr, Ni, and Zn distribution in the bay can be described by metal vs. grain size relationship. However, the distribution pattern of Mn, Co, Cu and Pb were found to be changed because they are anthropogenically enriched to sediment. Correlation matrix and R-mode factor analyses revealed that two important factors controlling the distribution of metals in the bay are grain size and anthropogenic input.

The purpose of this study is to investigate the moderating effect of anger expression styles on the relationship between school stress and interpersonal problem in adolescent. A total 300 students of middle and high school located in Chungcheongbuk-do completed the questionnaires to assess school stress, anger expression styles, and interpersonal problem during September to October, 2015 and 261 data were used in this report. Using multiple and hierarchical regression analysis, the results indicated that school stress, anger-in and anger-out significantly contributed to interpersonal problem. The interaction effect of school stress and anger expression styles were not significant. But anger-out significantly moderated the impact of school stress on domineering/controlling of interpersonal problem. These findings suggest that the intervention for preventing and relieving interpersonal problem in adolescent should focus on reducing school stress and maladaptive anger expression. Limitations and futre directions were discussed.
