The purpose of this study is to investigate determinants of partner opportunism in Korean discount store distribution channels. In addition, this study also try to examine moderating role of relational learning in the relationship. This study deals with transaction specific investment asymmetry, mutual hostages, payoff inequity, cultural diversity, and goal incompatibilities as determinants of partner opportunism. For empirical testing, 293 respondents of suppliers of discount store in Korea were surveyed and the analysis utilizing partial least square model indicated that TSI asymmetry, payoff inequity, and goal incompatibilities had positive effects on partner opportunism. On the other hand, mutual hostages had negative effect on partner opportunism. In addition, relational learning had moderating effect on the relationship between TSI asymmetry, mutual hostages, and payoff inequity and partner opportunism.

As we continue to enjoy economic growth, there is an abundance of disposable income for consumer to spend. Consumers are spending more and more of these income in beauty service. However, relatively little is known about which factors influence consumer' behavior intentions in this area. The purpose of this study is to investigate the relationships between the servicescape and relational benefits on customer value in beauty salon area. The Results are summarized as follows First, as the results of data analysis, among the composition factor of servicescape, spatiality, comfortableness, cleanness and convenience are shown to give positive effect on customer value. Second, among the composition factor of relational benefits, economic honest, functional benefit, private benefit, social benefit and psychological benefit are found to have a positive relationship with customer value.

This paper proposes an analysis method of petri nets(PNs) using the relational algebra(RA). More wpecifically, we represent PNs in relations of the relational model. Based on such representation, we first develop an algorithm for generating reachability trees of PNs. we then develop an algorithm for generating reachability trees of PNs. We then develop algorithms for analyzing properties of PNs, such as boundedness, conservation, coverability, reachability, and liveness. The advantage of this approach is as follows: First, the algorithms represented by RA can be easity converted to a query language such as SQL of the widely used, commerical relational database management systems(DBMSs). Second, we can alleviate the problem of state space explosion because relational DBMSs can handle large amounts of data efficiently. Finally, we can use the DBMS's query language to interpret the Petri nets and make simulation.

응용 시스템 개발 과정에 있어서 중요하고 핵심을 이루는 작업은 분석과 설계 작업이며 아울러 대부분의 응용 시스템은 데이터베이스 기반으로 구축된다. 또한, IT 시스템들 간 상호 연결이 증가되면서 응용 시스템들은 외부공격에 쉽게 노출되어 지고 있기 때문에 보안과 관련된 처리 과정 역시 중요하다. 보안은 시스템에서 많은 부분과 상호작용을 하는 복잡한 비기능적 요구사항이다. 하지만 이러한 보안은 대부분 개발 마지막 과정에서 고려하기 때문에 보안에 취약한 응용 시스템이 개발될 가능성이 매우 높다. 따라서 개발 초기에 보안을 반영한 분석 및 설계 과정이 매우 중요하다. J2EE는 웹 응용 시스템을 위한 보안 방안을 제공하고, 아울러 객체-관계형 데이터베이스도 보안을 위하여 역할기반 접근제어를 지원하고 있지만 객체-관계형 데이터베이스 및 J2EE의 역할기반 접근제어를 활용하는, 요구사항 수집부터 구현까지 개발 단계 전체에 걸친 보안을 고려한 일관된 개발방법론은 전무한 실정이다. 따라서 본 논문에서는 보안 요구사항을 요구사항 수집부터 분석 및 설계 그리고 마지막 구현 단계까지 반영하여 J2EE 기반의 웹 응용 시스템을 개발하기 위한, 보안을 고려한 일관된 통합 분석 설계 방법론을 제안한다.

This paper aims to define the relational logic of in-between code articles as well as within atomic sentences in Korean Building Code, as an intermediate research and development process for the automated building permit system of Korea. The approach depicted in this paper enables the software developers to figure out the logical relations in order to compose KBimCode and its databases. KBimCode is a computer-readable form of Korean Building Code sentences based on a logic rule-based mechanism. Two types of relational logic definition are described in this paper. First type is a logic definition of relation between code sentences. Due to the complexity of Korean Building code structure that consists of decree, regulation or ordinance, an intensive analysis of sentence relations has been performed. Code sentences have a relation based on delegation or reference each other. Another type is a relational logic definition in a code sentence based on translated atomic sentence(TAS) which is an explicit form of atomic sentence(AS). The analysis has been performed because the natural language has intrinsic ambiguity which hinders interpreting embedded meaning of Building Code. Thus, both analyses have been conducted for capturing accurate meaning of building permit-related requirements as a part of the logic rule-based mechanism.

Informal networks between individuals are widely seen as important in East Asian business systems. However, while the performance implications of guanxi in China have been extensively studied, much less is known on how informal networks may influence business outcomes in other East Asian countries. We examine informal networks in inter-organizational research collaborations in South Korea by studying the role of pre-existing social ties and relational orientation in new product development (NPD) collaborations and university-industry research (UIR) collaborations. We conduct an interview-based, in-depth case analysis of five NPD collaborations and five UIR collaborations. Pre-existing social ties and relational orientation are prevalent in both types of research collaborations. However, they have different consequences for collaboration outcomes. Pre-existing social ties strongly vary in their types and strength, and negatively affect collaboration outcomes unless they result in the selection of competent and motivated partners. Relational orientation manifests itself in a task-related and social exchange between collaboration partners, which contributes to outcomes such as knowledge acquisition and business performance. Korean collaboration managers should rely only on pre-existing social ties that are well-aligned with task-related requirements when initiating and conducting research collaborations. However, the creation of strong relationships between collaboration team members of partnering organizations should be encouraged.

의료 시스템이 개발되면 시스템이 사용하는 knowledge source의 신뢰도가 시스템의 수행능력에 큰 영향을 미치게 되므로, knowledge source의 신뢰도를 검증해야한다. 본 논문은 의료 시스템 CLINAID의 knowledge source의 신뢰성 조사에 대한 연구의 방법과 결과를 발표하였다. 그 방법으로는 CLINAID에 사용된 Cardiovascular body system 데이터에 fuzzy relational method를 적용하여 구조적 분석을 통해 만들어진 인공의 syndrome을 knowledge base에 저장되어있는 의료 전문가의 syndrome과 비교하였다. 7 가지 fuzzy implication operator를 사용하여 거의 비슷한 결과들을 산출해 냈으며, 그 결과들이 전문가가 제공한 syndrome과 거의 일치하였다.

It is widely agreed that customers' purchase are strongly influenced by their emotions. despite the obvious importance of eliciting positive emotional responses from customers, we find no record that family restaurants have ever measured or used customers' emotions as a management tool. This study aimed to verify the importance of the customers' emotion in the relational performance of family restaurant business. In order to achieve the object of the study, the effect of emotional factors on service satisfaction, revisit, word-of-mouth were analysed. The data were collected from 450 customers who had visited five family restaurants in Seoul more than once during the last three months from September 20 to October 5, 2002. Emotional variables in service experience process were grouped as three factors; in the middle of having food, in entering and leaving restaurant and in the waiting line. It is proved that customers had different emotions in each process of family restaurant service experience. Multiple regression analysis was employed to explore the influence of three emotional factors on relational performances such as satisfaction, revisit and word-of-mouth. It was found that customers were influenced by emotional factors in entering and leaving restaurant, secondly influenced in the waiting line and least influenced in the middle of having food. Finally, the findings indicated that customers' emotional factors in whole service experience process from entering to leaving the restaurant should be successfully cared by service staff. Future research is recommended to find out which specific emotional factors affected on relational performance of family restaurant.
