This study develops a framework and instruments to diagnose the current knowledge management(KM) status of an organization and to suggest future KM implementation directions. Based on the comprehensive review of KM literature and KM case studies, we derive three main aspects(strategic, social and technical aspect) and seven critical factors(KM strategy, knowledge worker, organizational strucuture, organizational culture, KM processe, organizational knowledge, and information technology) for the successful KM implementation. The instruments developed in this study include every specific measurement items of each critical success factor, which are expected to help not only suggest a context-sensitive KM strategy but also evaluate current KM status of a designated organization. By introducing two dimensions of KM evaluation(effectiveness and necessity), a more holistic and contingent view of KM can be assured. Academic contributions as well as practical implications are discussed. Study limitations and future research directions are also provided.

Minimum support and confidence have been used as criteria for generating association rules in all association rule mining algorithms. These criteria have their natural appeals, such as simplicity; few researchers have suspected the quality of generated rules. In this paper, we examine the rules from a more rigorous point of view by conducting statistical tests. Specifically, we use contingency tables and chi-square test to analyze the data. Experimental results show that one third of the association rules derived based on the support and confidence criteria are not significant, that is, the antecedent and consequent of the rules are not correlated. It indicates that minimum support and minimum confidence do not provide adequate discovery of meaningful associations. The chi-square test can be considered as an enhancement or an alternative solution.

Growth in the outsourcing market signals that firms of all sizes believe outsourcing will ultimately deliver many benefits and conveniences. But there are not many firms satisfied with the results of outsourcing. What is more, previous researches were fragmentary analyses focused on specific variables of outsourcing such as sourcing decisions, partnership rather than comprehensive analysis. Thus, they could not propose general systematic methodologies applicable to the real situation. To solve these problems, we developed an integrated theoretical framework that considered both contract with the hard side and trust with the soft side from a contingency viewpoint and tested this model using 143 data of Korean companies executing outsourcing. In addition, we examined how situational factors(outsourcing task complexity and outsourcing management competence) affects each path in the research model. The results of this study are as follows. First, it was proved the theory that trust is not a substitute for contract but its complement. Previous empirical studies on outsourcing success factors were focused on the establishment of successful partnership on the assumption that trust can replace contract in many situations. According to the results of our empirical analysis, however, contract and trust were in a mutually complementary relation with each other and their emphasis was different. Furthermore, different from previous researches, it was found effective to use trust as a supplementary tool and contract as a main means in outsourcing management strategy. Second, this study provided an integrated view that sees both contract and trust from a contingency viewpoint in theoretically reestablishing the relationship between contract and trust. Previous researches leaned to specific variables or theory-centered fragmentary analysis, but this study proposed a more practical and integrated research model and tested its effectiveness. Based on the results, with the model, decision makers are expected to scrutinize outsourcing situation more closely and to have a practical insight to the situation. Third, it was found that contract mechanism and trust building do not have a direct effect on outsourcing performance but relationship management intensity mediates the effect of contract mechanism and trust building. This is considered significantly meaningful to outsourcing partners who have believed that outsourcing would be successful if a contract is made properly or trust is built. Lastly, the path from trust building to relationship management intensity was moderated by informed buying, as the path coefficients from trust building to relationship management intensity varied by the degree of informed buying competence.

The almost studies that is related to an e-Trade and an e-Marketplace only have been focused on the diffusion and acceptance since the innovation was adopted in markets. The existing studies failed to notice the resistance of innovation in the course of accepting innovation. The resistance of innovation, however, is not the contrary concept of acceptance, it is should be understood as a construct which can explain the course of the diffusion and acceptance. This study will be analysed as follows: First, nevertheless the resistance of users is important, it couldn't be presented systematically through acceptance of innovation, accordingly the concept of resistance of innovation will derive concept from review of literature researched on prior researches. Second, the factors which can be affected to the resistance of innovation of the main trade firms which use the e-Marketplace will draw. Third, we identify some of determinants that can affect to resistance of user by empirical study, also we investigate how participation can be affected by using a contingency variable. The independent variables used through researched review are the characteristic factors of trade e-Marketplace which was consisted of relative advantage, suitability and complexity, the characteristic factors of trade firms which was consisted of propensity of innovation and attitude, and the characteristic of service quality which was consisted of reliability and reaction. This research also examines the association between independent variables and the resistance of user(dependent variable) by using a variable on participation of user(moderator variable). The sample surveys for this study have been used 109, this study was analysed by the SPSS 12.0 of statistical tool. According to the proved hypothesis there are three important factors which affected the resistance of user. One factor was the relative advantage and complexity from the point of view on the trade firms characteristics of e-marketplace, another factor was the propensity of innovation from the point of view on the trade firms factors, the third factor was the reliance from the point of view on the service quality factors. The results also provided that relative advantage and suitability among the characteristics of e-Marketplace and the reliability among the service quality characteristics have moderated in the moderated regression which was tested the association independent variables and dependent variables while participation of user was using for contingency variable.

기존 연구들은 기업가적 지향성에 영향을 미치는 선행 변수들과 기업가적 지향성의 성과 효과에 대해서 연구를 진행해 왔다. 하지만, 대부분의 연구들이 기업가적 지향성이 기업 성과에 미치는 영향을 다루었기 때문에, 기업가적 지향성에 영향을 미치는 다양한 선행 변수들에 대한 연구는 부족한 실정이다. 이에, 본 연구에서는 자원기반이론과 상황 이론을 기반으로 기업가적 지향성에 영향을 미치는 기업 특성과 환경적 특성 변수들을 실증적으로 살펴보고자 하였다. 225개의 한국 수출기업에 대한 실증분석 결과, 기업 규모와 국제화 정도, 기술 변동성과 시장 불확실성이 기업가적 지향성에 유의미한 영향을 미치는 것으로 나타났다. 이와 같은 결과는 기업 특성과 환경적 특성에 대한 종합적인 이해가 글로벌 시장에서 경쟁우위를 창출하는데 중요한 요소가 되는 기업가적 지향성을 형성하고 발전시켜 나가는데 중요하다는 점을 시사하고 있다.

This paper proposes an optimal load shedding algorithm by which the system loss can be minimized when the load shedding is unavoidable in case of severe contingency such as the outage of key generators or lines. Shedding load .DELTA.S = .DELTA.P + J.DELTA.Q(MVA) is performed on the weakest bus (on the view of voltage stability), step by step, by the priority of the I.DELTA. = SQRT(.lambda.$\_$P/$\^$2/ + .lambda.$\_$Q/$\^$2/) index given for each load bus, where .lambda.$\_$P/ and .lambda.$\_$Q/ are the sensitivity indices representing the system loss variation versus active and reactive power change of the bus load bus. All loads are assumed to be constant power loads for convenience. A 5 bus sample system proves the effectiveness of the algorithm proposed.

개인은 지식의 공유를 일종의 거래 행위로 지각하고 있다. 이러한 지식공유에서 발생하는 거래는 경제적인 거래라기보다는 조직과 종업원간의 관계의 성격에서 파생되는 특수하고도 복잡한 형태의 거래로 추측된다. 특히 개인들 간의 상호작용을 통한 지식공유는 상황과 긴밀한 상호관련성에 의해 형성된다. 따라서 지식공유는 사회적 교환관계에 의해 설명이 가능하다고 볼 수 있다. 공공기관에 종사하는 178명의 공무원들을 대상으로 설문을 실시하여 분석한 결과, 공공기관 내 구성원간의 지식 공유는 관계특성요인과 개인특성요인이 신뢰와 조직몰입의 형성에 영향을 미치고, 형성된 신뢰와 조직몰입이 지식공유의도에 영향을 미치는 순차적인 단계를 거쳐 이루어짐을 확인할 수 있었다.

The purpose of this study is to analyze the effects of strategic roles of IS and characteristics of ISP on the performance of ISP in view of contingency theory. In particular, this study is to find out whether there is a fit between two contingent variables. To evaluate the effects of two independent variables on the dependent variable empirically, a field research method using questionnaires with depth interview was employed. Findings of the field study are as follows: First, the main effect of strategic roles of IS on performance of ISP is found to be significant. This implies that the higher the strategic importance of IS, the better the performance of ISP expected. Second, the effect of characteristics of ISP on the dependent variable is also found to be significant. Organizations which recognize IT as an important competitive weapon for their business, and adopt Technological and Organizational approaches in ISP, have shown to obtain excellent results. Third, the interaction effect of two contingent variables is not found. There is no evidence for a fit between the strategic roles of IS and the characteristics of ISP. This shows that the differences of ISP performance are to be explained by only independent effect of two contingent variables.
