This cross-level study of 77 samples from Korean 1st-tier suppliers participating in knowledge-sharing networks examined the impact of partnering(joint establishment of goal and joint problem solving system) on supplier relationship outcomes(competativeness improvement and innovative idea suggestion). The findings showed that joint establishment of goal and joint problem solving system were positively related to both supplier's competativeness improvement and its innovative idea suggestion. Whereas, joint problem solving system did account for a significant variance only in innovative idea suggestion. The findings, further, demonstrated that mutual trust moderated the relationship between joint problem solving system and supplier relationship outcomes. Implications for theory and practice are suggested.

Simulation output knowledge analysis is one of problem-solving and/or knowledge adquistion process by investgating the system behavior under study through simulation . This paper describes an approach to simulation outputknowldege analysis using fuzzy neural network model. A fuzzy neral network model is designed with fuzzy setsand membership functions for variables of simulation model. The relationship between input parameters and output performances of simulation model is captured as system behavior knowlege in a fuzzy neural networkmodel by training examples form simulation exepreiments. Backpropagation learning algorithms is used to encode the knowledge. The knowledge is utilized to solve problem through simulation such as system performance prodiction and goal-directed analysis. For explicit knowledge acquisition, production rules are extracted from the implicit neural network knowledge. These rules may assit in explaining the simulation results and providing knowledge base for an expert system. This approach thus enablesboth symbolic and numeric reasoning to solve problem througth simulation . We applied this approach to the design problem of broadband communication network.

In resolving industrial quality control problems, a vector of multiple quality characteristic variables is involved rather than a single variable. However, it is not guaranteed that a multivariate control chart based on statistical methods can monitor abnormal signal in case that small changes of relationship between each variables causes abnormal production process. Hence a quality control system for real-time monitoring of the multi-dimensional quality characteristic vector under a multivariate normal process is needed to enhance tile production system quality performance. A pattern analysis approach based on self-organizing map (SOM), an unsupervised learning technique of neural network, is applied to the design of such a quality control system. In this study we present a new material quality control system based on pattern analysis approach and illustrate the effectiveness of proposed system using actual electronic company material data.

The demand of ubiquitous home network system is rapidly increasing in Korea as each construction enterprise makes a huge effort to introduce it to apartment complex. However, the design of home network system is rather technology oriented than the customer focused. Lack of knowledge about customer needs is an obstacle in spreading the ubiquitous home network system to the market regardless of technology development. In this paper, we propose a HCSI(customer satisfaction index for home network system) using an SEM(structural equation model) where structural relationship among several factors influential on users' satisfaction is considered. This model enables to calculate the satisfaction index for target customer group so that one can provide necessary feedback information for improvement of the home network system used for each group.

The effective management of knowledge has become one of the critical success factors in current organizations. In spite of the extensive use of Knowledge Management System (KMS), useful information and knowledge resources are still transmitted through personal networks among people in organizations. Thus, social network theory which focuses on social relationships in organization can be a fruitful theoretical resource for enhancing Knowledge Management (KM) performances. In this study, we investigate the effects of intra-team network characteristics (i.e., group density and degree of centralization) and external boundary spanning activities on knowledge management performances of a team. We also acknowledge that all group members do not necessarily agree on the team goal and actively disseminate useful information and knowledge. Drawing on the political perspective on KM which emphasizes the role of trust among group members, we examine the mediating effects of team trust between internal/external network characteristics and KM performances. From the data of 220 teams in financial companies in Korea, we found that: (1) group density had positive effects on KM performances (i.e., knowledge creation, sharing, and use). (2) However, centralization was not significantly associated with KM performances. (3) Team trust was found to be an important factor mediating the relationship between intra-team network characteristics, boundary spanning activities, and KM performances. Based on these results, we discuss and suggest possible implications of the findings when designing and implementing KM practices.

The purpose of this study is first, to find out what factors affect the cooperation and trust within the functions in the policy implementation network and in what mechanism these factors interact, second to investigate the whys to manage trust and cooperation successfully in the dynamic situation such as the network setting. For these purpose, this study reviews the concept and characteristics of policy implementation organizations, second, extracts the various factors affecting trust and cooperation in the network situation, third applies and analyzes the relationship among factors to system dynamics model based on the game theory. The results of this study could be summarized as follows: It was found that the utility change within the participants by persuasion ＆ mutual understanding and change of rule would be leading to success in policy implementation network. Also bureaucratic management such as power enforcement does not have any good impact in the managing network. In this study, system simulation method tried to analyze the hypothesis. Quantitative and case analyses were not accompanied and analysis was limited to two-person game theory. So there is some doubt this results could be generalized to actual situation which is N-person game.

본 연구는 최고경영자와 이사회의 네트워크밀도와 R&D투자 간의 관계와 이들 관계에 영향을 미칠 수 있는 기업분할의 유형과 제도의 영향을 분석하는데 주된 목적을 두고 실행되었다. 연구목적의 달성을 위해 외환위기가 발생하고 기업분할 관련법(상법 530조)이 제정된 직후인 1999년부터 가장 최근의 자료수집이 가능한 2016년까지 총 18년의 연구기간 동안 기업분할을 실행한 국내기업들을 대상으로 다중회귀분석을 실행하였다, 분석결과는 국내기업 최고경영자와 이사회의 네트워크밀도와 R&D투자 간에 유의한 정(+)의 관계가 있음을 보여주고 있다. 또한 기업분할 유형과 관련하여 최고경영자와 이사회의 네트워크밀도와 R&D투자 간의 정의 관계는 비관련분할에서 보다 관련분할을 실행한 기업에서 강화되었음을 보여주고 있으며, 기업분할 제도와 관련해서는 물적분할보다 인적분할을 실행한 기업들에서 이들 관계가 강화되었음을 보여주고 있다. 신속한 의사결정이 요구되는 사안임에도 불구하고 장기적인 관점에서 높은 수준의 불확실성과 위험을 수반하게 되는 R&D투자결정에 있어 최고경영자와 이사회 간의 네트워크밀도가 긍정적인 영향을 미칠 수 있음을 보여주는 본 연구의 분석결과는 최고경영진들 간의 신뢰의 중요성을 강조해 온 네트워크이론의 주장과 일치한다. 또한 혁신역량 강화를 위한 R&D투자결정에 있어 개인수준의 요인들뿐만 아니라 조직수준의 요인이 함께 고려되어야 함을 시사하고 있다. 본 연구는 향후 기업분할의 활용을 통한 보다 전략적인 국내기업 지배구조의 개선방안에 대한 연구를 강화하는 동기를 제공해 줄 수 있을 것으로 기대된다.
