This paper describes the design and implementation of an unmanned ground vehicle (UGV) and also estimates how well autonomous navigation and remote control of UGV can be performed through the optimized arbitration of several sensor data, which are acquired from vision, obstacle detection, positioning system, etc. For the autonomous navigation, lane detection and tracing, global positioning, and obstacle avoidance are necessarily required. In addition, for the remote control, two types of experimental environments are established. One is to use a commercial racing wheel module, and the other is to use a haptic device that is useful for a user application based on virtual reality. Experimental results show that autonomous navigation and remote control of the designed UGV can be achieved with more effectiveness and accuracy using the proper arbitration of sensor data and navigation plan.

The systems engineering standard process is intended to be customized for a given project environment and system characteristics. This study describes the experience gained by applying systems engineering to government-funded projects. The characteristics of government funded project are lack of common development process among the participating organizations and mechanism to determine system requirements. This study describes the contents of the systems engineering activities, including development of operational concept, system requirements, verification requirements (test cases), test verification plan, and implementation of system test and lessons learned from these activities.

Customer satisfaction is undoubtedly one of the top strategic issues in the new decade. Today, many organizations are rushing to become more customer focused. A key component of many initiatives is the implementation of customer satisfaction software. In this paper, we provide a case study for customer satisfaction management in a city gas company. The three issues include the plan for giving premiums and the development of a happycall system and a web-based measurement system for customer satisfaction.

This paper focuses on the method of setting priorities for telecommunications standardization work areas (SWAs) and standardization work items (SWIs), detailed sub-areas of each SWA. It is based on prioritization of SWAs to make a strategic plan that usually includes prioritization, resource allocation and standardization schedules for each SWA in telecommunications field. We applied the simple Delphi technique and the Analytic Hierarchy Process (AHP) to the prioritization process. We also introduce 0-1 integer programming for resource allocation using the AHP result. We present analyzed results according to the proposed process. The result of this study will be useful input for telecommunications standardization policy making and practical implementation.

인터넷, PC통신 등과 같은 전자적인 수단에 의한 상거래가 활성화되면서 효율적인 물류업계의 대용전략이 요구되고 있다. 전자상거래하에서는 상류부문 예를 들어 상품의 주문 및 결제가 전자적으로 이루어지기 때문에 고객들은 물류서비스에서도 신속한 배송을 원하게 되었다. 또한 물류활동은 상거래 관련 당사자간의 수많은 정보가 유통되게 되기 때문에 물류부문도 이러한 정보의 흐름에 신속한 접속이 요구된다. 본 연구는 전자상거래하에서 물류의 효율적 관리를 위하여 사이버 물류시스템의 구축을 모색하는 방안을 제시하는 데 있다. 사이버 물류시스템이 구축되면 물류관련 당사자간을 인터넷을 통한 연계성이 확보됨으로써 정보의 원활한 흐름이 가능해지며 이로 인해 전체 물류시스템의 효율화가 증진될 것이며, 이로 인해 국내외 전자상거래의 활성화에 크게 기여할 것으로 예상된다.

The deteriorated apartments make a social problem in now a days. After all a new alternative plan for deteriorated apartments such as the remodelling concept must be considered. This study aims to survey the needs levels among residents in deteriorated apartments relating to remodelling. It might provide the basic data which could be used for the analysis of consumers in the future implementation of deteriorated remodelling projects. The analytical methods applied for this study were t-test, one-way ANOVA, post-hoc estimation(Scheff test) by the SPSS 10.1 for Windows program. The analysis of the need levels for the areas of remodelling, by the family characteristic variable, residence value viewpoint, and residence satisfaction level, indicated that the demand level for ‘equipment ’was the highest, followed by the order of ‘structure’ and ‘interior’. The need levels for ‘security’, ‘parking lot’, ‘public facilities in apartment block’, and ‘landscape’ were generally low but in the group of high income, the need levels were comparatively high.

In accordance with the rapid industrialization in Korea, there have been remarkable changes in the health environment. The major changes are ; the change of disease structure, the aging of population structure, the diversification of health needs and the increase of health care costs. Because most of health problems stems from the environment, national health policy should be conducted according to the environmental changes. It is necessary for the voluntary organizations as well as the government ones to plan and participate the national health promotion movement on a national level so as to make the people form the attitude that health promotion is better than cure. Also, it is desirable that national health promotion movement be implemented gradually especially by four steps, 1) preparation step; 2) enlightenment step: 3) implementation step: 4) evaluation step.

In this study, we investigated the effect of carbon sequestration and sink on the environmental impact assessment of a housing redevelopment project. Through the case study, we found that the amount of carbon sequestration and sink increased with the increase of the area of park and green space and, furthermore, the amount of carbon emission decreased slightly with implementation of district heating and renewable energy. Therefore, it is necessary for its land use plan to be established to minimize the amount of net carbon emission, taking account of both the amount of present carbon emission and the amount of the future carbon sink, sequestration, and emission.

Management of today's dynamic projects requires a shift of focus from product to process. The purpose of traditional project controls is to conform performance to plan. The purpose of lean project controls is to make the best possible choices at each point in time during the course of the project, as well as contributing knowledge to the parent organizations so they can learn from project experience. The Lean Construction Institute(LCI) proposed the Last Planner System(LPS) capable of accomplishing that purpose, principally through controlling the quality of planning and of management processes themselves, as distinct from concentrating exclusively on project performance. The case project was a pilot project for the implementation of the Last Planner. Consequently, the coordination of the work on this project was extremely successful. The project had its share of challenges. The coordination did not prevent design problems, or supplier errors, but helped the team deal with the problems effectively while maintaining the work flow. The last planner helped the contractors know: a) who will be doing what and where, b) what each one needs from the others, and c) what are the project priorities. The system itself created a more collaborative environment, because it 'demands' that the subcontractors address these issues.

Despite the increasing interest in web contents and the rapid growth of CMS(Content Management System) market, the studies on the evaluation criteria for determining the purchase of the CMS solution are very rare. We introduce previous researches on the evaluation models of IT solution, and develop new criteria for evaluating CMS solutions. We calculate the relative importance of the evaluation criteria using scores from the IT experts based on the "Pair-wise Comparison" using the AHP. Based on the analyses of IT specialists′ responses, the results of the study show that, among the ten criteria, "the function of content management", "the contribution to the company′s business process" and "the fit with Information Strategic Plan" are the three most important ones over the remaining others. The developed model and criteria for the evaluation of the CMS solutions are expected to contribute on effective purchasing decision of the solutions and their successful implementation.
