Urban land consolidation, which is to reform land parcels to remove fragmentation and produce ideal blocks, is an effective means for urban renewal. Successful urban land consolidation brings out great benefits to the city officials as well as general public, such as improved city image, increased land value, and more effective land use. However, urban land consolidation can be detrimental to environment, especially in the ecological aspects, while the execution of land consolidation has been focused solely on development for the sake of human benefits. To remove negative effects of urban land consolidation to the ecological system, this paper is intended to establish a set of criteria for evaluating ecological impacts of an urban land consolidation plan. Firstly, key ecological indicators are identified using a special group decision-making process called "habitual domain analysis" and then individual weighting of each indicator is recorded by analytical hierarchy process. An urban ecological evaluation model with 4 levels and 23 indicators is thus developed.

The tire production facility is a large-scale construction with the complexity of a manufacturing process. The process utilities should be wide-ranging as an effective arrangement of them is highly important. All the necessary information should be clarified together with the manufacturer at the basic planning stage, and this design should be developed to comply with the local culture and regulations. It is important to carry out more advanced engineering in terms of process, cost and quality, even if it is difficult to standardize due to the cultural and geographical conditions and regulations. The key point is to reflect all the given conditions and make a clear design during the design stage, to eliminate the problems after the construction has begun. Another key point is the delivery system, which must be totally managed from the initial design stage until the construction stage by proven companies. Flexibility, quick action, and single responsibility will be the fundamental features in all the steps of the project.

The study aims to draw out implications regarding systematic reservoir management through analyzing the reservoir conservation activities and policies in Hyogo Prefecture which has the most agricultural reservoirs in Japan and similar agricultural form to that of Korea. The results are as follows. First, it turns out that consistency in policies and persistent drive are key to success. Since the late 1990s, the Hyogo Prefectural government has expanded the reservoir conservation policies, consistently trying to ellicit the multifunctionality of reservoir, and also has shown persistent drive toward the conservation policies through systematic process. Second, it is clear that the Prefectural government has shown a great degree of activeness. It established ordinances before acts were legislated by the central government. In addition, the Hyogo Prefectural government ran a supportive organization with its own funds. Third, the establishment of systematic enforcement system played a critical role. The efficiency in the policy enforcement derived from the dual conferences, Prefectural-level conference dealing with the related policies throughout the Prefecture, and local-level conference discussing policies based on regional characteristics.

Six Sigma is one of the most active subjects in quality management. This study deals with some existing weaknesses that may arise in implementing Six Sigma in real world situations. The main weaknesses discussed here include the lack of understanding of cultural aspects on the nations and industries, the poor linkage between quality, finance and accounting from the bottom line point of view, and the difficult development process of metrics for all improvement results to validate the effect of Six Sigma. Finally, the key success characteristics for a good Six Sigma project are presented.

최근 유비쿼터스 시대에 진입하면서 PDA,PMP, Smart Phone 등의 휴대형 정보기기의 보급으로 임베디드 시스템의 기능이 다양해지고 멀티미디어 기능이 강화됨에 따라 시스템이 처리해야할 정보의 양도 늘어나고 있다. 이에 따라 시스템은 대용량의 전력 공급이 필요하게 되었다. 그러므로 Battery라는 제한적인 에너지원을 사용하는 휴대형기기에서 전력 관리는 중요한 이슈가 되고 있다. 본 논문에서는 미아방지용 스마트 디바이스에 최적화된 젼력 관리 솔루션을 제공하는데에 초점을 맞추었다. CPU는 ARM9 Core를 사용하고 Windows CE 5.0을 Porting 하였다.

This paper examines to focus on General Strategy of e-logistics activity for SCM(Supply Chain Management) Build-up, especially the field service logistics integration. And this research analyzes the case study(Business of Strategy Group Unit) Survey involving effective logistics management that leads customer satisfaction, seeking to find out the key elements of competitive policy. Because problems arise from the differences between their goals and structures, which cause each side to feel vulnerable to opportunism or shirking of responsibilities by the other. The goal of a logistics system is to ensure that every family planning client always receives the contraceptives partner wants, and that they are in good condition and have not expired. In order to select, procure, and distribute the right quantities of the right contraceptives, managers of the logistics system must keep informed of the rates of use of each contraceptive and of the quantity of available supplies. As a result, We propose that a firm's e-logistics safe strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

GPRS(General Packet Radio Service) 서비스는 circuit 기반의 GSM(Global System for Mobile Communication)의 기본 망구조를 이용하여 packet 서비스를 지원하도록 변형시킨 모델이다. 기본적으로 GPRS는 GSM의 많은 부분을 계승하여 서비스를 지원하고 있기 때문에 GSM이 가지고 있던 문제점을 그대로 이어받게 되었는데, 본 논문에서는 사용자 인증 프로시져등에서 문제시 될 수 있는 부분들에 대해 살펴보고, 이를 보완 할 수 있는 방법으로 공개키의 암호화 모드와 인증 모드를 사용한 인증 프로시져와 시스템 구조를 소개하고자 한다. 또한 공개키 구조의 인증을 사용함으로써 필요로 하게 되는 키 관리에 대한 방법을 제시하고 앞으로 해결해 나가야 될 문제에 대해 언급을 하고자 한다.

현재 그리드 컴퓨팅 툴킷으로 사용되고 있는 Globus는 PKI (Public Key Infrastructure) 기반의 인증방식을 이용하고 있다. PKI 인증방식은 통합 인증 기능(Single Sign-On)을 구현하기에 적당하지만, 그리드에 참여하는 수많은 컴퓨터와 사용자들의 공개키 인증서(public key certificate)를 발급하고 관리해야하는 부담이 따른다. 본 연구에서는 인증기관이 사용자에게 인증서를 발급하고, 인증서를 관리하는 과정을 자동화 해 줄 수 있는 시스템을 개발하고, 다양한 클라이언트에 서비스 제공을 위해 웹서비스를 통한 인터페이스 기능을 새로 추가하였다.

Three major Asian countries, Korea, China, and Japan, shared 18.3% of global GDP and 14.2% of global trade volume in 2005. When considering this number, cooperation of these three countries is very important. Also, it is needless to say that we need efficient international logistics system in Asia. The key point to realize efficient international logistics system is unit load system utilizing pallets and containers. To build up efficient logistics system among Korea, China, and Japan, we need 'total palletization' with standardized pallets. We may regard 'total palletization' as an 'efficient highway of North-Eastern Asia logistics.' In this study, we will suggest two kinds of effects, which logistics standardization among Korea, China, and Japan will make. One is the effect on economy and trade, and the other is the effect on logistics business and environments.

Recently, community computing has been proposed for group formation and group decision-making. However, legacy community computing systems do not support group need identification for ad hoc group formation, which would be one of key features of ubiquitous decision support systems and services. Hence, this paper aims to provide a multi-agent based methodology to enable nomadic community computing which supports ad hoc need identification and group formation. Focusing on supporting group decision-making of relatively small sized multiple individual in a community, the methodology copes with the following three characteristics: (1) ad hoc group formation, (2) context-aware group need identification, and (3) using mobile devices working in- and out-doors. NAMA-US, an RFID-based prototype system, has been developed to show the feasibility of the idea proposed in this paper.
