The study attempts to review TQM models used in the health care sector and the obstacles to the application of TQM in the sector. Even though the TQM models in the manufacturing and service sectors were successfully applied, the applicability of TQM in the health care sector is still in question. The reason is the unique characteristics of the medical sector such as medical and management practices. The most of the TQM models in the health care sector come from manufacturing industries. The importance of the professional groups is, however, more emphasized in the sector than in manufacturing sector. The role of the groups are idiosyncratic to the sector. They generate some obstacles to the application of TQM in the sector. The barriers include cultural obstacles of health care organization. It naturally follows that the TQM in the health care sector requires the change of the organizational culture of the sector. The culture embraces the norms, rules, regulations, compensation system, morale, practices, and common experiences. To change the culture needs long term effort and modification of the rules, regulations, compensation system, and practices. It also requires staffs' training in the problem solving methods. The TQM in the health care sector needs that the interested parties should change. Since doctors group and nurses group are controlled in the bureaucratic and authoritative manner, they should learn the problem solving techniques which require the interaction with other groups. The management also needs to learn management skills and get thorough training on them.

Objectives: The purpose of this study was to analyze the effect of outpatient cost-sharing on health care utilization by the elderly. Methods: The data in this analysis was the health insurance claims data between July 1999 and December 2008 (114 months). The study group was divided into two age groups, namely 60-64 years old and 65-69 years old. This study evaluated the impact of policy change on office visits, the office visits per person, and the percentage of the copayment-paid visits in total visits. Interrupted time series and segmented regression model were used for statistical analysis. Results: The results showed that outpatient cost-sharing decreased office visits, but it also decreased the percentage of copayment-paid visits, implying that the intensity of care increased. There was little difference in the results between the two age groups. But after the introduction of the coinsurance system for those patients under age 65, office visits and the percentage of copayment-paid visits decreased, and the 60-64 years old group had a larger decrease than the 65-69 years old group. Conclusions: This study evaluated the effects of outpatient cost-sharing on health care utilization by the aged. Cost sharing of the elderly had little effect on controlling health care utilization.

This study shows the importance of human factors in relationship marketing by revealing the influence of Hanbok salesperson's attributes on relationship quality and long-term relationship orientation at the time when a culture is newly understood. A questionnaire surveyed 376 women living around the Seoul and Daejeon Metropolitan areas from February to March 2013. SPSS WIN 20.0 and AMOS 20.0 programs analyzed the gathered data. We review the influence of Hanbok salesperson's attributes (expertise, ethics, communication skill, customer orientation, similarity, and likeability) on relationship quality and behavioral intention. The research indicates that only customer orientation and Hanbok salesperson's expertise attributes influence relationship quality. All the attributes had a positive influence; in addition, the relationship quality had a significant influence on customer loyalty. However, communication skill, similarity, and likeability did not influence relationship quality. Customer orientation, which provides a customized service based on the recognition of individual customer trends and expertise in developing a relationship with customers, are important factors to form relationship quality and loyalty.

Designing mobile Interfaces is fundamentally different from designing online interfaces. Not only are there differences in underlying technologies, but also in the way people use mobile Interfaces. If these differences are not taken into account in designing mobile interfaces, mobile services are likely to fail. If mobile services do not deliver what people want, these services will fail no matter how excellent the underlying technology is. The user interface design commonly used in mobile services is based on multi-layered approach, which is not very user-friendly. A well designed single layered user Interface will be more user friendly than the conventional one and it will be having edge over others. However, it is quite difficult to Provide a single layered user Interface in a small screen. This study aims at examining how design attributes of mobile interfaces affect customer preferences. In order to explore customer preferences to each design attribute of mobile interfaces, we measure and analyze customer's WTP (Willingness To Pay) toward their different interface designs. Ultimately, throughout the study, we try to answer how to design mobile interfaces in small screen of mobile devices. In addition, we propose an optimal design solution that customers likely prefer.

ITU-T's NgN(Next generation Network) architecture is expected to offer a new Internet platforms such as QoS(Quality of Service) guaranteed services as it overcame the limitations of the existing best-effort Internet architecture. However, policy development crucial for the NgN framework(e.g., interconnections and billing) is lagging far behind technology development. For example, arguments over network neutrality clearly indicate little understanding of the Internet industry structure where diverse providers including ISP and CP coexist. This study employs a network economics approach to predict how the competitive landscape involving various providers will evolve under the traffic-based billing system under the NgN environment. Applied is the non-cooperative game theory, in particular, Stackelberg's repeated game in order to build and analyze model for competition among those providers. We also studied possible impacts that CPs would have on the competitive landscape if they have an option to replace ISP: i.e., CDN(Content Delivery Network) provider. Lastly, based on the model analysis and experiments, presented are their implications to policy development and tile future prospect.

Recently the need for renewable energy development is expanding due to the global climate change, the environmental issues and the limited fossil energy resources. Dependence of energy on overseas is high in Korea. To resolve the environmental problems and to improve the energy independence rate, the development of renewable energy is more required. The small hydro power, one of the renewable energy resources, has been developing and operating from a long time ago. If we are new developing a small hydro power with the use existing dams and reservoirs, we will design the length of inlet pipe and the diameter suitable for it. However, in case of using the existing water supply pipe which had been designed suitable for water service, the designer has to review and check that the pipe is suitable for operating a generator. In this paper, the design of small hydro power using the existing long pipe of water supply, we suggest the optimum way to reduce the water hammer in pipe which causes the unsteady flow during the load-shutdown of generator, the generator operation plan for the stable supply of water and the design factor of determining the generator capacity through the analysis between discharge and head-loss.

This article examines social determinants of population health in OECD countries, where life years, infant mortality, and PYLL are used as proxy variables of health. The unit of analysis is a country which is the OECD affiliate. A panel regression estimation is chosen as a method, using OECD Health Data. The results are: the increasing national health expenditure affected positively to improve population health. Education was rather a significant determinant of health than income level. The government direct investment for public health did not contribute positively to enhance population health. The expansion of health care coverage was working positively for improving health, but with a time lag. The supply of doctors was a most influential determinant of health. In case of Korea, the coverage expansion of health care was the most important determinant of health. The supply of doctors was, however, not a positive factor for better health, which is different result with the case of OECD countries.

Electronic transaction using electronic documents be carried without direct person to person meeting, there is the possibility to use other's identity illegally without notice and to verity authenticity of transaction. It is very hard to find out that the electronic documents on the process of submitting is forged documents or not and also has much difficulty in maintaining transmitting secret. Therefore, to solve such problems on electronic transactions, certification system with cryptography skill are inevitably necessary. Also there is needed legal base in the electronic document as functional equivalent of the paper document. Recently there are so many commercial certification service provider(CPS) such as Identrus, Bolero, TEDI but their establishment of CPS, certification process, guideline and so on are different each CPS. Therefore, this kind of situation can make user confuse. To introduce and develop the electronic certification in the international electronic commerce not domestic electronic commerce, it need to authorize and operate certification authority under the uniform regulation base. But, because the laws and guidelines that related to electronic certification system are different among the nations and international organizations, it need to compare laws and guidelines. In conclusion, the most important thing to resolve problems surrounded certification and develope certification system in the international electronic commerce make uniform rule of international electronic certification to recognize internationally from each nation or at least, need to harmony laws and guideline in each nations.
