  • E-authentication is one of the key functions for electronic transactions with the identification function made through the information systems. With the abolition of the mandatory use of public certificates, various private e-authentication services have emerged, and are developing to provide various additional services in addition to e-authentication. In this study, we explored the factors that affect user satisfaction with e-authentication services, compared the relative influence among the factors that we explored, and produced implications that could contribute to strengthening the competitiveness of e-authentication services. Based on the characteristics of e-authentication service, we searched and found four factors such as availability, convenience, added functionality and security. After that, we established and analyzed our research model to analyze the causal relationship between these four factors and user satisfaction. The analysis results showed that availability, convenience and security had significant effects on user satisfaction, but added functionality had no significant impact. In addition, compared to availability and convenience, security had a very strong impact on user satisfaction. This study suggests that e-authentication service providers should make efforts to make users aware of the usefulness of additional services while enhancing security.

  • Unlike profit-seeking businesses, hospitals provide medical services to promote the public good in a way, and they need a reform of management to ensure sustainable growth in fast-changing medical environments. The key to the managerial reform is enhancing efficiency, and inefficient managerial practices and factors affecting that should be grasped first of all to boost the efficiency of hospital management. But evaluation methods that are prevalent in the private sector are hardly applicable to hospitals. The purpose of this study was to assess hospital efficiency by using a data envelopment analysis(DEA). The 2006 data on 74 residency training hospitals with 500 beds or more were analyzed. The selected input variables included the number of bed, the number of doctors, the number of nurses, the number of medical technicians, personnel expenses, management cost and materials cost. And the selected output variables were the yearly number of outpatients, the yearly number of inpatients, the number of operation cases and earnings. In addition, the influence of the type of hospital establishment, location, the year of foundation and the type of hospital on hospital efficiency was checked as well.

  • This article attempts to explore how the women retirees under study were able to continue work until retirement. This study used life histories, especially focusing on daily working lives, and uncovered a number of key issues through in-depth interviews. The main results are as follows: Firstly, the women retirees examined here had been raised as highly educated people, and their strong educational background was a base component for them to have relatively secure careers. Their parents had also supported practically the women retirees during their working lives. In addition, the women retirees had to can out the roles of 'provider' for their original families, procreation families or in-law families, even though they were not given the recognized roles of provider. Secondly, the women retirees had a private infra system to support them with housework and child care. In addition, because they were financially able to employ housemaids, the women retirees did not experience conflicts with their husbands, who took on a neo-traditional sex role. Finally, thanks to relatively good working conditions such as having vacations and being able to come to and leave the office on time, the women retirees were able to continue work until retirement no mean feat in a society which openly practiced gender discrimination.

  • This study analyzes Korean childcare policy from a caring democracy perspective by using the normative policy analysis method. In the midst of emergent new social risks engendered by low fertility and aging population, feminist scholars proposed a transformative paradigm shift from economic growth to caring oriented development on a macro scale but researches on how this grand principle can be reflected into each policy have hardly been discussed. Thus, this study intends to contribute to such policy-driven discussion by analysing childcare policy on the basis of three normative values of freedom, equality and justice re-interpreted by caring democracy theory. Following are key findings. First, childcare policy does not guarantee public value and social solidarity due to the limitations of free choice from the perspective of freedom. Secondly, gender and class stratification has been worsened in a multiple and more complicated way by adding generational and racial dimensions to the existing gender inequality and vicious circulation of private care is observed from equality perspective. Thirdly, structural inequality aggravated injustice previously accumulated in the past rather than providing flat ground by adjustment.

  • It is said that global business education in Korea must be a kind of good investment on the future of Korea, because Korea's degree of dependence upon global trade is very high. But, despite great significance of trade in economic aspect, education system on global business in Korea still remains in old paradigm focused mainly on trade in goods. The purpose of this paper is to analyse key environment of trade in Korea relating to global business education system, and to suggest some trade-friendly measures to improve the global economic environment being worse. Methodology used in this study depends on descriptive analysis by literature study. As all the paradigm of global business has shifted from 20C's trade environment to that of 21C's and still more borderless trend has progressed, it is high time Korea to design the new education system of global business to conform with the trade mode of Korea, and to execute the mode of strategic trade which is new conception of trade strategy derived from Web 2.0 trend. Major findings of this study can be summarized as follows : It is suggested that Korea should convert basic composition of trade strategy to strategic trade irrespective of company size, nationality, public or private sector, etc., and launch new instructional model considering the trade 2.0 concepts. Also, Korea's trade policies which have been based on 'trade in goods' should be changed to the frame of strategic trade so that can include various trade process such as trade in services, trade in technology, cultural contents, global investment(TRIMs), TRIPS, etc.

  • Location-based concierge services (LBCS) are considered to be one of the main service functions provided in a city in ubiquitous technology spaces. A "Ubiquitous City" is defined as a city in which both public and private services can be delivered and received anywhere and anytime. One of the key elements that make location-based concierge services successful is the interoperability of location data. Currently, several existing technologies could provide LBCS including car navigation services and ubiquitous computing. However, lack of standardized structure for location data makes it impossible for heterogeneous technologies to be able to deliver uniform LBCS. The purpose of this paper is to develop standardized locational data structure so that heterogeneous technologies could provide efficient LBCS to all users of the various transportation modes.

  • As the Internet moves to mobile environment, one of the most serious problems for the security is to required a new security Protocol with safety and efficiency. To solve the problem. we Propose a new Protocol that reduces the communication franc and solves the problem associated with the private security keys supplied by the trusted third party. The protocol is a non-Interactive oblivious transfer protocol, based on the EIGamal public-key algorithm. Due to its Non-Interactive oblivious transfer protocol, it can effectively reduce communication traffic in server-client environment. And it is also possible to increase the efficiency of protocol through the mechanism that authentication probability becomes lower utilizing a challenge selection bit. The protocol complexity becomes higher because it utilizes double exponentiation. This means that the protocol is difficult rather than the existing discrete logarithm or factorization in prime factors. Therefore this can raise the stability of protocol.
