The deep seabed mining system is generally composed of surface vessel, lifting system, buffer, flexible pipe and miner. The milling system is regarded as a large-scale system in which each subsystem is interconnected to other one. In order to control a large-scale system, a decentralized control approaches have been proposed recently. In this paper, as a basic study on application of decentralized control, firstly, the mining system is simplified modeled, where the lifting system and buffer is regarded as a spherical pendulum and tile flexible pipe is as a two-dimension linear spring. Based on the derived model, the system characteristics and the feasibility of decentralized control are analyzed.

This paper aims to evaluate the regional development model related regional cooperative system, especially, with the governmental-educational-industrial mutual cooperative establishment plan for regional development to propose the basic direction pursued by engineering colleges, regional development policy and policy of science and technology. It proceeds through the analysis of the distinctive qualities of modern scientific technique and the system to pursue it's policy, and the study of the necessity and concepts of regional cooperative system. For this, the present condition and main issues regarding the cooperative research system among the government, education and industry complex such as the regional consortium projects and the regional cooperative research center etc, are analyzed and examined. Besides these, questionnaire survey method for experts on regional development is used concerning the regional cooperating system, their ongoing cooperative research, main issues and the roles of the mutual cooperative system. In conclusion, it proposed evaluating methods for solidifying cooperation and development of mutual relations between regional development and regional cooperative system.

This study is a case study focusing on the residents' participation and satisfaction in the promotion of rural development projects under the Block Grants System in Buyeo. Along with changes in the way to support rural development projects, it requires the autonomy, responsibility, creative planning etc. in the municipal governments and the active participation of local residents for the effective development in rural areas. The purpose of this study is to suggest some policy implications by analyzing the relationship between the level of participation of local residents and residents' satisfaction in rural development projects. This study explained the background and characteristics of rural development projects under the Block Grants System, and also reviewed the theoretical literature on the residents' participation and satisfaction, including the survey of the local residents. For this study, we selected some variables, and then divided into the participating groups such as the resident representatives, the development committee and the local residents. Finally, using statistical method we analyzed the level of participation and satisfaction of the local residents in rural areas.

According to the New Town Development Plan, Gang-buk area, a symbol of slum in Seoul will be changed new residential area. There are a lot of challenges for success this project. First of all, new ways of city plan "pre-plan and development" and "environmentally friendly development" are necessary to carry out this plan. Another important idea is how to overcome conflicts such as unbalanced development, a traffic jam and environment problem. Also, Government and a citizen agree that this project have to accept eco-protectable and sustainable development theory. For increasing green area ratio and keeping eco-diversity, planting at roofs and water circulation system in residential complex are compulsory. Green network based on environmentally friendly development provides a natural energe stream on eco-system and protects a city from air pollution, hot air island phenomenon and a flood.

The protection of nuclear safety software is essential in that a failure can result in significant economic loss and physical damage to the public. However, software security has often been ignored in nuclear safety software development. To enforce security considerations, nuclear regulator commission recently issued and revised the security regulations for nuclear computer-based systems. It is a great challenge for nuclear developers to comply with the security requirements. However, there is still no clear software development process regarding security activities. This paper proposes an integrated development process suitable for the secure development requirements and system security requirements described by various regulatory bodies. It provides a three-stage framework with eight security activities as the software development process. Detailed descriptions are useful for software developers and licensees to understand the regulatory requirements and to establish a detailed activity plan for software design and engineering.

In spite of the perceived importance of sustainable development in society, we still fails to reflect consistently our best understandings about the sustainable development and education for sustainable development. The purpose of this study is to inquire into the orientation of education for sustainable development in the 21st Century knowledge-based society. The results of this study can be summarized as follows. First, it is necessary to provide newly defined sustainable development which enables us to transform unsustainable way of life into environmentally sound and sustainable development. Education for sustainable development is defined as a basic education that have a mature understanding among the human, nature and wisdom of life. Second, we should emphasis on a system thinking, basic communication in order to encourage education for sustainable development as a learning strategy. Third, we should suggest both individual and community learning education for sustainable development. Finally, we develope knowledge system of sustainable development in accordance with the theories of knowledge management. In conclusion, it is necessary to approach education for sustainable development in the context of the knowledge-based society and the information age. It enables us enhance a new awareness and attitudes towards sustainable development. Furthermore, it is expected to develop an education program for the sustainable development of understanding.

South and North Korea, the divided nations on the Korean peninsula, began with the same modern city planning system, but following the adoption of different national ideologies-capitalism and socialism-, they established their own city planning system and developed their cities accordingly. However, the process of planning and developing a joint city of Kaesong Industrial Complex (KIC) led to the recognition about the need to bridge the differences and prepare for future joint development. This study examines North Korea's city planning system by comparing the two Koreas' systems, and identify the characteristics of North Korea's city planning system through a case analysis of the KIC. By comparing two cases, we found two distinct characteristics of North Korea's. The one is a tool for realizing ideologies and maintaining national system. The other one is that it is ideology-oriented system for the supreme leader and party while South Korea has control-oriented system for the public. We analyze the KIC case based on four pillars: planning system, development system and procedure, master plan, and use behaviors. Result of analysis shows that in KIC there are many socialistic features as we mentioned above in terms of planning system, urban design & structure, and use behavior even though a private enterprise-Hyundai Asan, in South Korea led the whole process. This study is meaningful in that it identifies the specific characteristics of North Korea's city planning focusing on the KIC and is expected to serve as a baseline material to set the future direction for North Korea's development.
