기업의 경영환경은 급속히 변화하고 있으며 특히, 새로운 경영패러다임으로 가치중심의 경영사고는 급속히 그 중요성을 인정받고 있다. 이러한 경영환경의 변화에 대한 신경영기법의 활용에는 원가/관리회계정보가 기초적 역할을 수행하고 있는데, 과거 지향적인 정보보다는 실시간적이면서 동시에 미래지향적인 정보를 제공해야만 경영의사결정에 도움을 줄 수 있다. 이러한 실시간적 정보와 미래 지향적인 정보의 중요성을 인식하면서 조직을 가치창출 중심적인 방향으로 움직이게 하기 위해서는 조직내 구성원 및 조직의 성과평가가 중요한 문제로 대두될 수 있다. 그러나 과거와 같이 전통적인 성과측정치로 재무적 측정치를 사용하면 조직의 유효성을 증진시키는데 한계가 있을 뿐만 아니라 가치창조를 저해시킬 소지도 있다. 따라서 앞으로 조직을 가치 지향적이 되게 하기 위해서는 조직의 구성원 및 조직단위의 성과를 측정할 때, 재무적인 측정치와 비재무적인 측정치의 균형있는 사용을 강조하는 Balanced Scorecards개념을 도입하는 것이 바람직할 것이다.

본 논문에서는 TRW사의 InGaAs/GaAs p-HEMT 공정의 쇼트키 다이오드를 이용하여 Ka대역용 하향수신변환기에 이용할 수 있는 MMIC(Monolithic Microwave Integrated Circuit) 주파수 혼합기를 설계 및 제작하였다. RF는 30.6∼31.0 ㎓이고 LO 9.8 ㎓를 이용하여 IF 20.8∼21.2 ㎓를 얻을 수 있는 본 MMIC 주파수 혼합기는 발룬의 크기를 줄이기 위해 LO와 IF 단자를 서로 바꾸어 설계함으로써 전체 회로의 크기를 줄일 수 있었다. 제작된 MMIC 주파수 혼합기의 크기는 3000umx1500um이며 on-wafer 측정 결과 대역 내에서 7.8㏈ 이하의 변환손실을 얻었다. 또한 27㏈ 이상의 LO-RF 격리도, 19㏈ 이상의 LO-IF 격리도 및 39㏈ 이상의 RF-IF 격리도를 각각 얻었다.

The central government has implemented policies to strengthen the competitiveness of small and medium sized cities for balanced development at the national scale. However, since it is often difficult to enhance the competitiveness through partial projects of each jurisdiction, many local governments collaborate at the regional scale. This suggests that a regional approach is important for the management of small and medium sized cities. On the one hand, the concept of network city suggests that various functional networks can affect the growth of small and medium sized cities. Given this background, the purposes of this study are to delineate regional boundaries at national scale and identify their relations of growth by using functional network and Moran's I index. The study uses the Markov-chain model and cluster analysis to delineate the regions, and Moran's I is employed to identify the relations of growth. The results show that interactions between jurisdictions through networks could be crucial factors for growth of small and medium sized cities, while the networks based on passenger travel and freight movement have different implications. The results suggest that policy makers should not only consider local level investments, but also take the characteristics of networks between cities into account for achieving balanced development and developing regeneration policies.

We develop in this work a new well-balanced preserving-positivity path-conservative central-upwind scheme for Saint-Venant-Exner (SVE) model. The SVE system (SVEs) under some considerations, is a nonconservative hyperbolic system of nonlinear partial differential equations. This model is widely used in coastal engineering to simulate the interaction of fluid flow with sediment beds. It is well known that SVEs requires a robust treatment of nonconservative terms. Some efficient numerical schemes have been proposed to overcome the difficulties related to these terms. However, the main drawbacks of these schemes are what follows: (i) Lack of robustness, (ii) Generation of non-physical diffusions, (iii) Presence of instabilities within numerical solutions. This collection of drawbacks weakens the efficiency of most numerical methods proposed in the literature. To overcome these drawbacks a reformulation of the central-upwind scheme for SVEs (CU-SVEs for short) in a path-conservative version is presented in this work. We first develop a finite-volume method of the first order and then extend it to the second order via the averaging essentially non oscillatory (AENO) framework. Our numerical approach is shown to be well-balanced positivity-preserving and shock-capturing. The resulting scheme could be seen as a predictor-corrector method. The accuracy and robustness of the proposed scheme are assessed through a carefully selected suite of tests.

SCM system is required inter-industrial cooperation as well as inter-organizational cooperation. It means not only standardization of inter-organization but also standardization of inter-industry. SCM makes possible one circulation from fiber to retail industry in the respects of information and product flows. QR is the SCM of textile apparel industry, which satisfy customer need with least cost and maximum profit. Customer-oriented supply chain system focused on information sharing, cost reduction, inventory control, lead time reduction, quick response on customer demand. How we can measure the performance of successful SCM is issued on the approach of Balanced Scorecard which evaluates 4 perspectives such as customer perspective, internal business perspective, financial perspective, and innovation and learning perspective. This can project the blueprint of textile fashion business to right direction with vision.

This paper proposes a new model to· evaluate the effectiveness of websites using balanced scorecard (BSC) and weighted formula based methods.fisrt, we Use BSC method to find out the cause-and-effect relationships between the measure and website activities, and our proposed model evaluates website performance from six perspectives: business value, operational excellence, customer value, website interface, management, maintenance, and learning and innovation. Next, we usedformula-based approach to identify what makes website performance low by developing the evaluation formula through investigating website users; finally, case studies of two famous websites are given to show how our method can be used Our evaluation model can not only evaluate website performance but also suggest how to improve performance.

Evaluation of the implementation and performance of a firm's green supply chain management (GSCM) is an ongoing process. Balanced scorecard is a multi-criteria evaluation concept that highlights implementation and performance measures. The literature on the framework is abundant literature but scarce on how to build a hierarchical framework under uncertainty with dependence relations. Hence, this study proposes a hybrid approach, which includes applied interpretive structural modeling to build a hierarchical structure and uses the analytic network process to analyze the dependence relations. Additionally, this study applies the fuzzy set theory to determine linguistic preferences. Twenty dependence criteria are evaluated for a GSCM implemented firm in Taiwan. The result shows that the financial aspect and life cycle assessment are the most important performance and weighted criteria.

This paper presents a method of a line balanced assembly sequence generation based on the verification of a disassemblability and a work time. To derive the disassemblability for a part to be disassembled, first we inference collision free assembly directions by extracting separable directions fur the part. And we determine the disassemblability defined by the separability and stability cost. The separability cost represents a facility of the part disassembly operation, and the stability cost which represents a degree of the stability for the base assembly motion. Based upon the results, we propose a new approach of evaluating work time using neural networks. The proposed assembly sequence generation provides an effective means of solving the line balancing problem and gives a design guidance of planning assembly lay-out in flexible manufacturing application. Example study is given to illustrate the concepts and procedure of the proposed schemes.

We describe a formal approach to the construction of optimal classification rule for the two-group normal classification with equal population mean problem. Based on the utility function of Bernardo, we suggest a balanced design for the classification and construct the optimal rule under the balanced design condition. The rule is characterized by a constrained minimization of total risk of misclassification, the constraint of which is constructed by the process of equation between expected utilities of the two group conditional densities. The efficacy of the suggested rule is examined through numerical studies. This indicates that, in case little is known about the relative population sizes, dramatic gains in accuracy of classification result can be achieved.
