This paper discusses WBS (Work Breakdown Structure) that is known for technique of basic project management. The WBS use in domestic industries often exhibit errors in Its structure. The most common serious error is space-oriented breakdown structure of PBS (Product Breakdown Structure) that becomes the core element of the WBS. This paper proposes a method to correct the problem of space-oriented breakdown structure constructed in domestic railroad industry. DSM method was adopted to construct PBS containing function-oriented structure. The proposed process and method will contribute to minimize time that take to construct an accurate and useful PBS.

The Spring framework including the MVC design concept is the standard in web development in the JAVA environment. The programming style of the structure must be kept strictly, so every web program is able to employ the same structure. It is convenient to distribute jobs, but there are some side effects, like duplication of code, deterioration of professionalization, and deterioration of program performance. To ameliorate those problems, we propose the horizontality development method(HDM) on Spring MVC. We proved that the HDM can solve the problems through the experiment to keep the MVC structure.

The use of CAD/CAM systems is growing fast in the shipbuilding industry. To develope a geometric modeler, the existing CAD/CAM systems have been analysed. Because existing systems have closed architectures, it is not easy to investigate the internal structures. However, new trends in the software engineering, open architectured systems, pose some possibility to develope the geometric modeler. Several geometric modelers are analysed to extract component functions and modules. ACIS of the Spatial Technology, AIS of the CAM-I consortium, the STEP part for the geometry and topology, CAD*I of the ESPRIT project, and domestic modelers are investigated. Based on this analysis, a reference model which shows the framework of the modeler is proposed. With the data structure supporting non-manifold topologies, the reference model can be used to encourage a cooperative development program.

The purpose of this study is to compare and analyze the organizations for responses in disaster fields to cope with large-scaled disasters including Emergency Management Agency, Emergency Response Unit, Emergency Support Center, and Field Command Center (Field Command Office). According to the results of the analysis, the problems of the organizations for responses in local disaster fields are; 1) the scopes of roles among the organizations for responses in disaster fields are ambiguous, 2) the structures of the organizations for responses in disasters are different each other, 3) the integrated management functions among the organizations for responses in disasters are overlapped, and 4) the one who assumes the integrated command is not defined. In order to improve the problems, first, the range of working of each organization for responses in local disaster fields should be definitely established and an agreement in services among the organizations should be settled in advance. Second, similar designs in the structure among the organizations for responses in disasters are necessary for amicable communication. Third, the works for integration and management for each organization for responses should be apportioned. Fourth, the organization in charge and the one who assumes the integrated command for each type of disasters should be appointed in advance for rapid decision-making.

우리나라도 2000년 들어 65세 이상의 노인인구는 7.2%를 넘어서서 본격적으로 고령화사회(aging society)에 들어섰다. "21세기는 고령자의 세기"가 된다고 해도 과언이 아니며, 2019년에는 14%가 넘어 고령사회(aged society)로 진입할 전망이다. 그러나 우리나라는 "고령자의 세기"라고 불릴 만큼 사회구조가 변화하고 있는 시점에서 노인 인구의 0.3%만이 시설에서 보호를 받고 있으며, 나머지 99.7%는 일반가정에서 생활하고 있다. 유교사회의 전통규범에 의해 99.7%의 노인들이 가족에 의해서 그들의 노년을 보내고 있으나, 핵가족화와 산업화에 따라 윤리규범이 깨어지고 있는 탈윤리시대에서, 더 이상 요보호 노인(와상노인, 중풍노인, 치매노인), 장애노인 등의 수발 및 보호는 윤리적 규범이나 가족, 가정에 의해서 충족되기는 점차 어렵게 되어 가고 있으며 극명한 한계를 보이고 있다. 이러한 사회적 상황과 가족부양체계의 변화는, 고령자를 대상으로 하는 각종 복지 시책 개발, 특히 재가노인 복지서비스의 필요성이 제기되고 있으나 우리나라는 아직 미미한 수준에 머물러 있다. 우리나라 재가노인을 위한 정책의 활성화와 서비스의 양적 확대 질적 고도화를 위해서는 첫째, 보편적으로 이용할 수 있도록 대상 범위를 확대해야 한다. 둘째, 의료서비스의 확충과 같은 전문적 서비스의 확대 실시가 요청된다. 셋째, 동일한 서비스내용에 대해서는 전달체계를 일원화할 필요가 있으며, 사업주체별로 역할을 분담하고 담당 인력별로 업무를 분담해서 전문성을 강화해야 한다. 넷째, 재가복지 서비스는 중앙과 지방의 분담에 의한 무료 서비스인 만큼 지원을 획기적으로 개선 나가며, 보편적 이용의 정도가 큰 서비스는 점차 정부지원의 서비스로 확대하되 저소득층에 대하여는 무료서비스를 제공하고 저소득층 이상에 대해서는 소득 수준에 따른 차등적 서비스 요금을 부과하는 것이 바람직하다. 그리고 보다 질 높은 서비스를 원하는 중산층 이상에 대하여는 시장 경제원리에 의한 실버산업이 활성화되어야 하며 일본에서 시행하고 있는 개호보험제의 도입방안도 적극적으로 검토되어야 할 것이다.

In this study, the structure and management of social group with each town, leadership with self-action and network with external organizations will be the main topic. Especially, the condition which make a communication with external organizations for localization is examined as an example of Mori village. As rice productivity has more serious problems than 1990s, many farming systems changed from rice productions to different kinds, like grapes. Particularly, this market and field started with the exchange system between local farms and cities because of the complex structure of grape circulation and increasing import for extra income. Extra income of farming is started to increase because of exchange program between local towns and cities. But, those works are concentrated on one or two leaders. It could be a burden for them. So. we need to change this into new system which the work is not concentrated to few leaders but distribute to everyone.

Simulator is composed of several devices that have a variety of forms and functions. These devices are connected to each other by a network intricately. For this reason, simulator development and maintenance process require a lot of time and money. In order to successfully develop the simulator, it is ideal that related professionals share the work and work together in parallel. However, development is carried out inefficiently, because task interdependence makes it difficult to work in parallel. In this paper, the developments of the simulator were classified into algorithm development and system development, and it was discussed how to lower the interdependence of these two tasks and support professionals. In particular, based on the requirements analysis of the domain experts responsible for the development of the algorithm, we designed the support tool for simulator development and proposed development process using this tool. We also introduced the concept of a DataSet in order to support algorithm development of domain experts and manage data flexibly. And we designed network architecture to enable flexible reconfiguration of simulator equipment. By using the tools to support the simulator development, domain experts are able to concentrate on algorithm development and it is expected to be effective collaboration. In addition, the development plan and management are expected to be easy because the development process is systematic and clearer.

This study has been conducted as a basic research for developing efficient ways of managing Korean National Parks by finding differences via the comparison of present management systems of national parks in Korea and Japan. The survey was conducted through telephone interviews and direct interviews with staffs of related organizations as well as related literature study. In result, it is found that Japanese national parks have a numerical standard of minimum area, with less staff than Korea, and larger designated areas are being managed. Management organizations of both countries are divided as main and commission. In Korea, 6 staff in Natural Resources Division under Ministry of Environment are managing main organization, and in Japan, 53 staff of 3 divisions(National Park Division, Natural Environment Management Division, General Affairs Division) are taking charge of it. Moreover, General Affairs Division, dividing whole country into 11 blocks, manages 11 units of natural preservation offices, 12 branch offices, and 67 units of nature preservation management offices. In case of commission, Foundation of Natural Park Beautification & Management in Japan has a headquarter and 20 branch offices with 54 staff who are only doing site management, while in Korea, the National Parks Management Corporation has a headquarter and 25 offices with 748 staff carrying out main office jobs and site management side by side. From the differences in both countries, we could suggest efficient measures for our national park management as follows: \circled1 introduction of numerical value as criteria for national park designation, \circled2 review of use zone, \circled3 division of the national park management office into site office and regional office, with dividing works and re-posting staff, \circled4 enlargement of park management division in Department of Environment, \circled5 National Park authority becomes a national public servant
