  • With a swift development of information technology, web sites get more important roles as user's living places. This quantitative and qualitative expansion of web sites requires the need for an evaluation framework of web sites from comprehensive perspectives. This study proposes two dimensions for web site categorization and three dimensions for web site evaluation. These dimensions were developed based on the architectural perspectives that have been used to evaluate buildings in the real world for more than a thousand years. First, in order to categorize various web sites, we extracted two dimensions, user's goals and user's behaviors from behavioral architect which approaches user's behaviors in designing buildings. Second, in order to evaluate four web sites groups, we suggested three dimensions, which are firmness, commodity, delight used in evaluating buildings in the real world. Then for each of the four different web sites groups an empirical survey was conducted to verify these three dimensions of architectural metrics. This ends with study implications and limitations.

  • The current study explored the factors that affect the addictive use of facebook. This study focused on the relationship between personal characters and the addictive use of facebook. To define the addictive use of facebook, various issues and the definitions of the Internet addiction were first considered in the theoretical background. Then depression, extroversion, openness, and communication competence were considered as the personal characters. Data were obtained by online survey and 600 responses were gathered. The results revealed that depression predicted the higher degree of the addictive use and low communication competence positively affected the addictive use of facebook. However, after controlling for communication competence, depression and extroversion were both associated the addictive use of facebook. Further, social compensation perspectives and social enhancement perspectives, and the policies on the SNS addiction were discussed.

  • The purpose of this research is to understand users' information protection behavior on personal information security from health psychology theory perspectives. Empirical results indicate that users' information protection behavior on personal information is predicted by perceived threat and perceived responsiveness. Perceived threat is determined by perceived susceptibility and perceived severity. Perceived responsiveness is determined by response efficacy and self-efficacy, but response cost is not significant. These findings provide an enriched understanding about users' information protection behavior on personal information security.

  • The drastic structural changes in telecommunications industry are imposing new strains on operators, regulators and customers. Many researchers have offered diverse frameworks for the changes from the perspectives of sociology, technology, and/or economics. However, there have been few attempts to document the competitive phenomena from management perspectives because of the technological complexities and dynamism in the fundamental transition of competition. In this study, we examine competitive environment in telecommunications industry, and identified five structural elements; telecom operator, competitors, regulation, suppliers, and customer demand. The suggested framework is used to provide a basis for explaining the changes in the characteristics of individual elements and the interactions among them. The dynamic industry-specific changes will be explained through an evolutionary model. We specify the characteristics of progressive stages and the determinants of the evolution. Changes are reviewed in terms of five criteria; regulations and competitions, value chain, technology, customers demand, and internal operations. The result of this study will be useful in analyzing and predicting industry structure and major participants' strategic behaviors and decision patterns. This study can alse be extended to other industries facing dynamic structural changes.

  • This paper analyzed four different perspectives on health care reform in Korea in terms of the basic values, formulated problems and reform plans, implementation methods, and supporting groups. The medical security plan was insisted by social security specialists and social activists focusing on the integration of medical insurance coops in order to enhancing equity and right of the people. However, its perspective was limited to promoting security instead of reforming health care system. The government proposed the health care reform plans in 1994 and in 1997, focusing on promoting efficiency by remedying many problems in health care delivery system. However, its implementation was not successful due to the lack of organizational and financial supporters. Recently, two opposite proposals were issued. The market reform plan paid attention to revitalizing the market function to promoting efficiency by allowing hospitals to treat private patients instead of applying the medical insurance regulation. The government reform plan focused on intensifying governmental planning and intervention in the health care sector in order to removing inefficiency and promoting equity with the supports of social activists and labor unions. Finally, this paper proposed an alternative plan to promote harmonious social relationship between actors in the health care system.

  • In contrast to many of the malignant tumors that occur in the central nervous system in adults, the management, responses to therapy, and future perspectives of children with malignant lesions of the brain hold considerable promise. Within the past 5 years, remarkable progress has been made with our understanding of the basic biology of the molecular genetics of several pediatric malignant brain tumors including medulloblastoma, ependymoma, atypical teratoid rhabdoid tumour, and high grade glioma/diffuse intrinsic pontine glioma. The recent literature in pediatric neuro-oncology was reviewed, and a summary of the major findings are presented. Meaningful sub-classifications of these tumors have arisen, placing children into discrete categories of disease with requirements for targeted therapy. While the mainstay of therapy these past 30 years has been a combination of central nervous system irradiation and conventional chemotherapy, now with the advent of high resolution genetic mapping, targeted therapies have emerged, and less emphasis is being placed on craniospinal irradiation. In this article, the present and future perspective of pediatric brain malignancy are reviewed in detail. The progress that has been made offers significant hope for the future for patients with these tumours.

  • This study examined and compared the two perspectives of consumers and employees on the perceptions toward visual merchandising (VMD) of fashion brands in a department store. Importance of VMD elements, roles of VMD, evaluations of VMD elements, and brand and store images were measured and compared. The two types of questionnaires were used to collect data from consumers and employees. A total of 327 consumer samples and 317 employee samples were analyzed. The results showed that there was no difference between the two groups in what VMD elements were the most important. While employees perceived of the role of VMD higher than consumers, consumers evaluated two VMD element factors higher than employees and showed higher store image. Such results were not different by brand types. The study implies that the higher VMD perceptions of consumers are desirable to manage VMD from the employees' perspective.

  • Variable loads along the drive-train are attributed to frequent failures of gears, bearings, and other components. Wind parameters cannot be controlled and therefore any turbine load-reducing remedies must be established based on proper insights into the wind-turbine interactions. A novel control concept to performance optimization of wind turbines is presented. This proposed concept is based on analysis of the turbine status reflected in the SCADA data. Modern computational techniques are used to optimize performance of a wind turbine from tree basic perspectives: drive-train, power output, and power quality. The proposed approach demonstrates that gains in the metrics representing the three perspectives and the corresponding control goals can be significantly improved for any wind turbine. The solution is applicable different turbine types operating in different wind regimes, e.g., winds of different speeds and variability. Simple and transparent parameters allow an operator to determine a balance between the operations and maintenance, technical, business objectives. The proposed modeling framework was embedded in software. The software tool has been tested on the data collected from 1.5 MW wind turbines.
