This paper proposes an integrated model of customer loyalty in the context of Internet shopping based on a review of two competing perspectives - transactional and relational views. The research model suggests that the usability and trust associated with an Internet shopping site are key determinants of customer loyalty. In this paper, factors such as promotion, ease of use/navigation, and purchase facilitation are posited as major determinants of usability. Trust, on the other hand, is assumed to be influenced by the quality of communication, social shopping service, and safety level associated with an Internet shopping site. This paper also asserts that the lack of consideration for individual differences is one of the key reasons for the inconsistent and mixed research findings in user acceptance literature. In this regard, the elaboration likelihood model (ELM) is considered to be appropriate referent theory as it may theoretically explain why a particular information technology (IT) related message has varying influences on different adopters. The research model comprising 11 hypotheses was derived from and validated through a survey involving 271 university students. The partial least square(PLS) method was used to test the suitability of the research model and its hypotheses. Overall, the results suggest that the usability and trust associated with an Internet shopping site play an important role in acquiring loyal customers. In particular, the user's Internet shopping involvement is found to moderate the relationship between trust and customer loyalty.

The purpose of this study is to detect the factors which have an effect on transformation level and performance and to provide the ways of successful transformation and vitalization from OEM to ODM. This study was proceeded by an empirical analysis. A model and hypotheses were set up and they were verified through the empirical analysis. Those factors were divided into four, inner company factors, strategic factors, core competence factors and purchase determining factors. In the result of the model suitability analysis on the study model of relationship among 'influencing factors of ODM transformation - ODM transformation level-export performance', every factors, $X^2=912.067$, DF=261, p value=0.000, GFI=0.737, AGFI=0.620, NFI=0.786, IFI=0.837, CFI=0.834, Q value=3.495 were rather insufficient to be a good model, but they were good enough for the general analysis. Taking these accounts into consideration, this study suggests the following implications. First, making a plan and setting up strategies in advance are required. Second, financial plan has to be prepared. Third, trends in global markets have to be analyzed. Fourth, companies have to focus on developing new materials and products through R&D. Fifth, quality competitiveness and quality control systems are required.

Trade can be greatly influenced by the change of international trade environment due to the characteristics of remote transactions. Furthermore, in the circumstance of emphasizing the national security again, the importance of the risk management of special materials has been increasing. As it was noted at Chapter 4, significant results such as the threat of enterprises' sustainable growth can be occurred when companies are related to the unlawful export of strategic materials or experience discouragement of export of main products. As the decision of strategic materials greatly depend on a specialized knowledge there is a possibility of misjudgement of strategic materials in terms of ordinary companies which is not accustomed to them. Furthermore risk management is more difficult due to the inclusion to the items of export license. To prepare such a risk of export of strategic materials, firstly, it should be checked to find whether counter traders are working in the industry which is not related to the spread of weapons of mass destruction, secondly, an appropriate process shall be designed and operated for products to be safely delivered to the trade counter. Therefore, our export enterprises have to introduce CP(Compliance Program), AEO or ISO28000 considering suitability for their actual situations not only to promote export and but also to avoid risk of export control and additional expenses. Through these appropriate processes, an efficient and effective management of the trade risk of strategic materials can be accomplished.

Nonpoint sources of pollution (NPS) is defined as diffuse discharges of pollutants (e.g., nutrient, pesticide, sediment, and enteric microorganism) throughout the natural environment and they are associated with a variety of farming practices. Previous studies found that water soluble anionic polyacrylamide (PAM) is one of the highly effective measures for enhancing infiltration, reducing runoff, preventing erosion, controlling nonpoint source of pollutants, and eventually protecting soil and water environment. Potential benefits of PAM treatment in agricultural soil and water environments have been revealed by many research and they include low cost, easy and quick application, and suitability for use with other Best Management Practices (BMPs) for NPS control. This study reviews the various applications of PAM and discusses its further potentials in agricultural environment.

유도전동기는 회전에 필요한 자계를 유지하기 위해 무효전력을 필요로 한다. 만일 전원측을 대신하여 부하측에서 무효전력이 제공될 경우 역률은 향상될 것이다. 유도전동기의 역률은 대개 낮으므로 커패시터로 보상이 필요하다. 내선규정에서 유도전동기의 역률 보상 커패시터의 용량은 출력에 따라 추천된 값의 설치를 권고하고 있다. 그러나 유도전동기는 같은 출력에서도 회전수에 따라 특성이 달라지므로 역률이 일정하지 않아 용량에 따라 일정한 커패시터의 적용은 부적합하다. 그래서 본 논문에서는 같은 출력조건에서 속도에 따라 기존에 제시된 값과 비교한 결과 역률 보상 커패시터의 용량이 약간 높게 설정되어야 함을 확인하였다.

Geomancy(風水, Fengshui in Chinese) is a geographic idea of the Orient that studies a piece of land(a site) to pursue the healthier and more comfortable life for people seeking a harmony with nature, and also, a practical science. Among the theoretical systems of the traditional geomancy handed down by the scriptures, the compass school(理氣論) makes researches into mountains, winds, the currents and amount of water circulation by using luo-pan(羅盤) for finding spot(穴), and it has been considered that it is the objective and logical analysis system of natural environment of selecting a good site by dividing the vitality of the ground into 12 levels of natural circulation principles and judging its direction by means of 88-direction method. In this context, researcher optimized the logic of 88-direction method by the 12-circulation system(胞胎法) of the compass school on the basis of directional theory, then after, using GIS analytical tool, researcher performed comparative analysis between the results from land suitability analysis of the subject site and the resulting value of the directional method in geomancy. The results therefrom indicated that more flexible directions and site could be chosen by applying 88-direction method. For the future research, it is required to apply wider variety of variables to the field study and more careful review of the case study with a focus on the 88-directiont method.

Public acceptance is a major issue that will determine the future of nuclear energy. In this article, we review relevant studies and identify several common patterns of nuclear public acceptance. Based on these patterns and four categories of factors, we propose hypotheses on the impact of different socioeconomic factors on the public opinion of nuclear energy. These factors were demographic and social influences, politico-economic, energy conditions, and nuclear accidents and natural risks. We tested these hypotheses using a data set including survey results on public opinion of nuclear energy in 59 countries from 1987 to 2014. Results of the regression analysis generally verified the proposed hypotheses, especially regarding the positive impact of education or geological suitability and the negative effect of improved living standards and democracy on nuclear acceptance. We propose policy recommendations, including a better focus on education and communication and a thorough consideration of the social and geological conditions a country needs to make before deciding to go nuclear. Potential weaknesses of this study are also discussed, including the possible causal relation between independent variables and the binary nature of the dependent variable.

This paper focuses generally on the ‘fourteen principles of management’ by Henri Fayol. However, it specifically analyses their application to and implications for libraries and information centres. An extensive review of published works on management generally, and library management in particular, was conducted. This yielded vital insights on the original meaning and later modifications of these principles, as well as their application in the management of various organisations. Consequently, the strengths and weaknesses of these principles were examined to determine their suitability in libraries and information centres. Inferences, illustrations, and examples were drawn from both developed and developing countries which gives the paper a global perspective. Based on available literature, it was concluded that Fayol’s principles of management are as relevant to libraries as they are in other organisations. The paper, therefore, recommends that in addition to modifying some aspects to make these principles more responsive to the peculiar needs of libraries, further research should be undertaken to expand the breadth of these principles and ascertain their impacts on the management of information organisations.

The purpose of this paper is to review the state of laser processing technology using metal powders. In recent years, a series of research and development efforts have been undertaken worldwide to develop laser processing technologies to fabricate metal-based parts. Layered manufacturing by the laser melting process is gaining ground for use in manufacturing rapid prototypes (RP), tools (RT) and functional end products. Selective laser sintering / melting (SLS/SLM) is one of the most rapidly growing rapid prototyping techniques. This is mainly due to the processes's suitability for almost any materials, including polymers, metals, ceramics and many types of composites. The interaction between the laser beam and the powder material used in the laser melting process is one of the dominant phenomena defining feasibility and quality. In the case of SLS, the powder is not fully melted during laser scanning, therefore the SLS-processed parts are not fully dense and have relatively low strength. To overcome this disadvantage, SLM and laser cladding (LC) processes have been used to enable full melting of the powder. Further studies on the laser processing technology will be continued due to the many potential applications that the technology offers.
