Government-funded research institutes in the field of science and technology of Korea have contributed to the growth of the national economy and industrial development since the 1960s. However, those institutes recently have faced with criticism over the R&D performance on investment. Accordingly, we suggest two analytical approaches that estimate the economic benefit of the R&D performance of those institutes, (1) 'bottom-up' approach that aggregates the economic benefits of individual performances, e.g., technology transfer, technology support for small and medium enterprises, and the supply of researcher manpower and (2) 'top-down' one that estimates the contribution of those institutes on the economic growth of the industries that the R&D performance of those institutes is mainly utilized. In addition, by applying two approaches, we computed the economic benefit of the performance of the K institute in the 1996-2014 periods at 12.3 trillion won and 29.5 trillion won, respectively. Lastly, we suggest the feasibility of two approaches from the perspective of complementarity. Our study provides analytical approaches that estimate the economic benefit of the R&D performance from government funded research institutes in Korea. Lastly, our study contributes to the understanding of public on science and technology as well as the enhancement of legitimacy on those institutes among the public.

The purpose of this study is to examine the effects of corporate social responsibility on organizational identification and customer orientation by flight attendants. In this study, 2 hypotheses based on literature reviews were employed. Questionnaire was also developed based on previous studies. A convenience sample of 217 flight attendants was surveyed and 203 usable questionnaires were analyzed. Corporate social responsibility was divided into economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility by the literature review. Confirmatory factor analysis were conducted to validate the measured variables. Then the data and hypotheses were examined using structural equation modeling (SEM) by AMOS. The results are as follows. Firstly, 'economic responsibility' and 'philanthropic responsibility' have positive effect on organizational identification while 'legal responsibility' and 'ethical responsibility' have no effect on 'organizational identification'. As for the degree of influence, 'philanthropic responsibility' has a greater impact than 'economic responsibility'. Airlines should focus on the responsibility to the community as well as social contribution. Secondly, 'organizational identification' has positive effect on customer orientation. The contribution and limitations of this research were discussed and the future possible researches were mentioned.

The Hippocratic database model recently proposed by Agrawal et al. incorporates privacy protection capabilities into relational databases. Since the Hippocratic database is based on the relational database, it needs extensions to be adapted for XML databases. In this paper, we propose the Hippocratic XML database model, an extension of the Hippocratic database model for XML databases and present an efficient access control mechanism under this model. In contrast to relational data, XML data have tree-like hierarchies. Thus, in order to manage these hierarchies of XML data, we extend and formally define such concepts presented in the Hippocratic database model as privacy preferences, privacy policies, privacy authorizations, and usage purposes of data records. Next, we present a new mechanism, which we call the authorization index, that is used in the access control mechanism. This authorization index, which is Implemented using a multi-dimensional index, allows us to efficiently search authorizations implied by the authorization granted on the nearest ancestor using the nearest neighbor search technique. Using synthetic and real data, we have performed extensive experiments comparing query processing time with those of existing access control mechanisms. The results show that the proposed access control mechanism improves the wall clock time by up to 13.6 times over the top-down access control strategy and by up to 20.3 times over the bottom-up access control strategy The major contributions of our paper are 1) extending the Hippocratic database model into the Hippocratic XML database model and 2) proposing an efficient across control mechanism that uses the authorization index and nearest neighbor search technique under this model.

In 1997 the recession of Korean economy brought about the bankruptcy of large corporations and the large size of non-Performing financial assets which led to IMF financial crisis. One of the major reasons for IMF financial crisis was poor loan management of domestic financial institutions . During the restructuring process of financial institutions since the IMF financial crisis, the importance of the loan management has been recognized. Especially. financial institutions' credit allocation had been concentrated on a few big conglomerates and their subsidies as well as some specific business areas. Hence, risk-diversifying portfolio effects were not reflected in any loan portfolios. The IMF financial crisis in 1997 has clearly showed that credit-risk management is essential not only for individuals' loan but also for portfolios consisting of various loans The main objective of this paper is to provide some suggestions on the direction for financial institutions in Korea to improve their loan portfolio management. Particularly, for the effective management of loan portfolios, this paper introduces quantitative credit-risk management schemes such as KMV models and CreditMetrics which are commonly used in financial institutions in advanced countries. Financial institutions in Korea should make their best efforts to establish a more scientific as well as quantitative loan portfolio management.

Cooperative associations are established in order to enhance the rights and the interests of their members and serve the local communities, and actually do much for the local society. And among these, consumer cooperatives are spontaneously founded, particularly in the spirit of mutual help, in order to promote the common welfare of the members. Meanwhile, because the current medical law qualifys noncommercial corporation to open medical institution, consumer cooperative and noncommercial- corporation cooperative which are established under the Cooperative Act have the right to do. However, though cooperative association should be founded for common interests of the members who are weaker parties of society, it became rapidly to be abused as means of circumvention of law. Especially as National Health Insurance Corporation stepped up the investigation and the collection of unfair profits against the hospital owned by non-medical personnel who are unable to establish a medical institution, setting up medical institutions as a roundabout way to avoid the restricts dramatically increased in number. In this study, we are going to introduce the current dualised normative system regulating the establishment of a medical cooperative association, and find a way to improve the system and make up for the week points. And we will look though the present situation about medical cooperative association's opening, operating, and closing, and review the normative and systematic improving plans.

As Internet has become a popular media for sharing information, users create and share tremendous volume of information including large amount of personal information in cyberspace. Sharing private information online can enhance strength of social relationship but it could also bring negative consequences like information privacy invasion. Although many companies and governments address the importance of information privacy online, there are countless cases of crimes and hackings relating personal information online world wide. Since there are some researches investigating the role of governments and organizations on online privacy domain but there is little research regarding users' privacy protection behaviors. This study investigates relationship between Internet users' information privacy protection behavior and environmental factors. Especially, this study focuses on users' behaviors regarding information privacy protection technology adoption. According to our research results, users' online privacy protective behaviors positively affected by governmental regulations expressed as an information privacy protection law. In addition, if user is allowed to use anonymity when he or she uses online services, they have more tendencies to adopt privacy protection technologies. The detailed research findings and contribution are discussed as well.

This paper is to give Korean small and medium enterprises the direction for strengthening the competitiveness through looking the problems and improvements about the government policy that domestic small and medium enterprises is essential for the growth anc development. To derive these results, the theoretical background was established through considering the existing research literature. This paper has drawn the final policy alternatives through collecting field data and analysing the practical support after meeting with executives that are operating a small business related to research purposes. In this paper in order to strengthen the competitiveness of small and medium enterprises of the government's support policy, it is critical for the financial support policy and the tax support policiest policy. The conclusions in this study are following. SMEs in Korean economic growth contribute greatly to advance industrial structure, regional balanced development, employment opportunities and to alleviate the concentration of economic power. However, there are these positive, and the negative such as the absence of entrepreneurial spirit and passive participation in society. Therefore, SMEs now should have your own a lot of effort to improve their competitiveness. In addition, government believe that SMEs directly impact on the national economy, especially the people, but they still need systematic and aggressive policy support in the future because of the lack of the result. Finally, if they try strategic approach for several issues and improvement of government's support policy that this study suggested for SMEs, the entrance toward developed countries can be through jumping of Korean economy.

Since the invention of the integrated circuit (IC) in 1950s, semiconductor technology has undergone dramatic development up to these days. A complete semiconductor is manufactured through a diversity of processes. For better semiconductor productivity, fault detection and classification (FDC) has been rigorously studied for finding faults even before the processes are completed. For FDC, various kinds of sensors are attached in many semiconductor manufacturing devices, and sensor values are collected in a periodic manner. The collection of sensor values consists of sequences of real numbers, and hence is regarded as a kind of time-series data. In this paper, we propose an algorithm for detecting and clustering faults in semiconductor processes. The proposed algorithm is a modification of the existing anomaly detection algorithm dealing with symbolically-represented time-series. The contributions of this paper are: (1) showing that a modification of the existing anomaly detection algorithm dealing with general time-series could be used for semiconductor process data and (2) presenting experimental results for improving correctness of fault detection and clustering. As a result of our experiment, the proposed algorithm caused neither false positive nor false negative.
