As a community of practice (CoP) is known to facilitate team learning, it is increasingly important to understand the mechanisms of CoP, thereby enabling organizations to fully utilize it and optimize its benefits. To explain how CoP improves organizational performance, we focus on its effects on social capital and knowledge management activities, and propose a research model suggesting that shared goals and trust in CoP improve its performance through knowledge integration. Our analysis uses structural equation modeling, with field data collected from 372 members of 46 CoPs in three companies; the analysis validates our research model. Our findings also suggest that CoP diversity can strengthen the link between knowledge integration and CoP performance.

Technology innovations have been accelerating changes across industries and intensifying competition. Enterprises are therefore required to continuously secure their internal and external competitiveness. Based on the principle that core competencies of a firm are essential to its competitiveness, many research studies have been conducted to figure out the effect of core competencies to business performance. However, individual research works considered a part of core competencies or limited to a specific industry, which means that their findings may differ when additional core competencies are included in their analysis. After re-establishing the definition of each core competency from literature review, this study comprehensively investigated the effect relationship among core competencies and business performance. Structural equation modeling and multiple regression analysis with 421 survey respondents from various industries were conducted for our empirical study.

A comprehensive understanding of functions and performances enables a selection of appropriate alternatives to the existing design and can prevent defective design. A performance-based design quality management can ensure successful project completion. This study proposes a new model for design quality management in order to prevent defective design and to minimize design change. The new quality management model defines the requirement about function and performance based on technical characteristic, and assesses suitability for design alternatives. This study attempts to propose a quality matrix assessment method that can compare the alternative design and requirements defined with the new quality management model. This method can judge conformity and suitability of design quality in accordance with the requirements configured.

Many tertiary hospitals have started to establish cooperative relationships with small and medium sized hospitals in Korea. But the performance of the relationship is not satisfactory to both of partners. The relationship and performance of cooperation for small and medium sized hospitals are analyzed according to the framework of inter-organizational cooperation. Data are collected by 4 focal hospital and 34 small and medium sized hospitals through interview and questionnaire. The findings are : a) The cooperation is focused on management area, such as healthcare technology transfer and information sharing, rather than patient referral. b) Patient referral is not yet active in cooperative relationship. But some partner hospitals which is located close and managing internal organization for cooperation show a significant number of referrals. c) The characteristics of high performers are positive attitude about cooperation, and recognition of the relationship as flexible, experiences of cooperation, internal and external management activities.

품질관리는 일본의 성공에서도 볼 수 있듯이 경영성과를 결정하는 중요한 요소이나, 품질관리의 성과는 비재무적인 척도로 측정되어 경영자의 경영성과에 반영되지 못했다. 즉, 품질관리활동이 수익성 지표로 전환되지 못하여 실질적인 경영수단으로 그 역할을 다하지 못하고 있다. 반면에 품질원가 이론은 품질관리의 성과를 재무적 척도로 측정하려는 시도이지만, 적절한 측정수단이 없는 것이 문제이다. 이를 위해 본 연구에서는 품질관리성과를 재무적 척도로 측정하여 수익성지표와 연결할 수 있도록 활동중심원가계산을 도입하여 품질원가를 측정하여 품질 관리성과를 평가하는 방법을 제시하고, 이의 효용성을 설명하기 위해 중소기업의 사례를 이용하여 설명하였다.

The central issue in this particular research is the seemingly inadequate achievement of optimum performance in the construction process, either with respect to value for money for the client and the entire construction supply chain or value in terms of the utility derived from built assets in spite of efforts by government and governmental bodies such as the Construction Industry Development Board (cidb) to increase industry performance. Therefore, based upon an extensive review of related literature, the paper reports on effects and causes of non-value adding activities in the construction industry in general, and South African construction in particular. The research findings indicate that activities that can be referred to as non-value activities are not only prevalent, but they can also be held responsible for performance related issues in terms of cost, time, quality and health and safety (H&S) in construction; and the exploration of pluralism in the research methodology may result in a robust model based upon the system dynamics approach.

Appropriate performance evaluation is a key successful factor for continuous improvement and systematic management support in the implementation of quality management. This research deals with the development of a computer support system for performance evaluation of quality management and its application to a real world problem. It, first, investigates existing performance evaluation methods and classifies them into three styles. A number of key factors for designing computer support systems are then elicited by analyzing the characteristics of the existing methods in terms of the requirements needed for a successful evaluation tool. The computer support system is designed by incorporating the key factors in the system design process and it is implemented as a network version. Finally, a case study is performed in order to verify the proposed support system. The pros and cons of the system are also discussed.

Purpose: The purpose of this study was to determine the factors that influence the performance and importance of clinical nutritionists. Methods: Ninety-nine nutritionists working in mental health institutions were assessed. Results: Factors affecting the performance of clinical nutritionists in certified hospitals were shown to have a significant positive effect on the description of treatment diet, status of clinical nutrition management, and presence of a nutrition counselor. The factors affecting importance were the number of permission beds and total work experience. Conclusions: In order to improve the accreditation system of mental hospitals, it is necessary to expand the scope of this study to include hospitals with fewer beds, and clinical nutrition management should be mandatory.

Most traditional database systems exploit a record-oriented model where the attributes of a record are placed contiguously in a hard disk to achieve high performance writes. However, for read-mostly data warehouse systems, the column-oriented database has become a proper model because of its superior read performance. Today, flash memory is largely recognized as the preferred storage media for high-speed database systems. In this paper, we introduce a column-oriented database model based on flash memory and then propose a new column-aware flash indexing scheme for the high-speed column-oriented data warehouse systems. Our index management scheme, which uses an enhanced $B^+$-Tree, achieves superior search performance by indexing an embedded segment and packing an unused space in internal and leaf nodes. Based on the performance results of two test databases, we concluded that the column-aware flash index management outperforms the traditional scheme in the respect of the mixed operation throughput and its response time.
