The information revolution is sweeping through the global economy. The strategic significance of the information and information technology have been some what underestimated. Now they are transforming the structure of competition. Information technology must be applied to improve and sustain an organization's competitive advantage. The successful implementation of information technology is dependent on the effectiveness of information systems planning. However, the selection of the right methodology still remains a open question. This paper describes the existing methodologies for information system planning. A complementary approach to strategic information systems planning, which was developed for a steel company, is suggested. The approach attempts to combine Business Systems Planning of IBM and Critical Success Factors Analysis for effective information systems planning. Although this approach is in the experimental stage it looks to be of benefit to large organizations which require information planning for managerial level.

The purpose of this study is to analyze how Korean traditional characteristics(traditionality) are reflected in contemporary multi-housing planning since 1997 and to draw its typical way of expression. Through this study, the following conclusions have been reached; The First, Socio-cultural characteristics have affected the planning concept of the multi housing planning in the three way ; traditional philosophies, community space and regional traits. The Second, Two characteristics of space planning were shown in drawings, sketches and photographs; territorial, hierarchic, surrounded space in exterior planning and intermediated spaces in interior planning. The Third, Ornamental characteristics of architectural and landscape design were found; the architectural structure, the traditional landscape, patterns and colors. In conclusion, this study found two types of expression of the Korean traditional characteristics. The first is ‘concrete planning’which was focused on traditional ornamental elements such as forms and colors. And the second is ‘abstract planning’which was focused on the traditional space planning in interior or exterior, philosophy, communal organization and regional characteristics by interpretation of architects and designers. This study shows that the combination of two types of the traditionality will be more ideal in multi-housing planning rather than relying on just one type.

The purpose of this study is to show the relation of the change between spacial structure and social conditions of rural area. The spacial structure change of Asan city was analyzed using Space Syntax, and multiple regression analysis (dependent variables: connectivity, global integration, local integration / independent variables: population, household, farm population, farm population of 65years old and over, farm household, part-time farm households, cultivated land) was accomplished. As th result, that the increase of connectivity is related to the increase of population and farm population of 65years old and over and the decrease of farm population, and the increase of local integration is related to the increase of farm population of 65years old and over was showed. However, that global integration is not related to change of social conditions was proved.

Feature based design approach is widely studied for the application of mechanical part design and process planning. Mechanical parts are associated with volumetric form features in nature. Therfore, one of the important characteristics that reside in the form feature research until now is that features have been studied in connection with CAPP for material removal. We studied the application of feature based design for ship structure design. Ship structure has interesting nature that tis distinct from mechanical parts. Among these are multiple cell structure, non-volumetric part and production by welding or assembling. An idea of applying feature based design paradigm for design, process planning, cost analysis and engineering calculation was shown. Non-manifold geometric modeler ACIS was adopted to fully benefit from the non-manifold nature of ship structure.

Current global issue of climate change is growing and greenhouse gases occur in most cities. To solve the problem of climate change, the city should be changed to low-carbon structure. Low-carbon city planning is a step-by-step plan from the initial establishment, from design and operation of urban structure, to maintenance and management should be considered as an integrated whole process. Under this background, this study evaluated the whole process of low-carbon urban planning ways. For this step, divided into three steps and eight divisions, 30 sub-indicators are derived. Through domestic and foreign cases analysis studies and survey of the relevant experts, results were derived. In order to improve these points, in the intial planning establishment stage, planning of urban policy and institutional steps should be made and the plan should be appropriate to the local characteristics. In the design and operation of urban structure stage, detailed and feasible approach is needed and maintenance and management stage, participation of various stakeholders, including establishing governance and management practices could see the need.

Japan has been tried to integrate Western planning theories into its parks and green systems in the past. However this effect has been regarded unsuccessful. One of reasons for this is that the green systems have been treated as an urban facility, instead as systems. Another reason has to deal with greenbelt's stationary and reservation characteristics that make difficulty to respond timely to the rapid urbanization. The parks and green systems in Korea was introduced in 1990 and began to be promoted fully with the 'Parte and Green Master Plan' established in 2005. However, due to its short history, incomplete aspects exist in its philosophy and methods for promoting the system. Based on these experiences, the current green zone plans in Japan considers the green structure as an independent institution and amenity plan, not a tool of urban planning, that can be a medium for realization of urban visions. And main characteristics of this approach are 1) classifying the green structure into four categories in order to respond to urban forms and purposes, 2) pursuing confirmity with urban planning, and 3) executing the landscape plan based upon core green areas. From reviews upon experiences of Japan as well as considerations on demands and conditions of green systems in Korea, we proposed the following five new strategies for the construction of the urban parte and green system in Korea. They are 1) to develop urban parks and green systems into a genre of urban development improving the quality and local competitiveness of cities rather than a means of urban planning; 2) to form the integrated structure of urban green zones; 3) to transform the urban parte and green systems into practical systems as the centers of localities; 4) to raise criteria for planning and execution plans for effective implementations of the urban parte and green systems, and 5) to provide specific guidelines for the construction of urban parks and green systems through organizing research groups or specialists.

The Yatomi - Aioiyama line is a city-planning road that was notified in 1957 and subsequently prepared by land readjustments. Currently, approximately 900m of road pass in the inside of the Aioiyama green area has not been constructed. The surveying briefing session for inhabitants was held in July 1992, the project was authorized by the Ministry of Land, Infrastructure and Transport in September 1993, and the project briefing session for inhabitants was held in September 1993. The site purchase has been completed. At the May 2000 briefing session, inhabitants of the area began voicing dissenting demanding the conservation of the natural environment of this green area. The inspector system serves as the third party, independent of both the administration and the inhabitants. Before finalizing the geometric line form of the road to be constructed, some surveys of animals and plants found along the walking trails carried out intensively in the northern area, which is approximately 50 ha, of the Aioiyama green area. The natural environment inspector submitted a plan for changing the geometric line form of the road decided upon by city planning, and it was approved by the city planning council. If the shelter structure or the retaining wall structure is adopted at the location where large slope faces are produced by excavation or landfill, and if the bridge structure is adopted at the place where stream-lines and walking trails intersect, it leads to a reduction of approximately $40\%$ in the areas for which change is planned. Furthermore, approximately $20\%$ of the area to be changed is restored by returning soil to the roof of the shelter.

Cell planning, which determines the cell structure for location management of mobile terminals in mobile communications, has been dealt with as an important research task to determine network performance. Among the factors influencing the cell structure planning in mobile communication, the signal cost for location management plays the most important role. In this paper, we propose an optimization algorithm that minimizes the location management cost of all the cells used to plan the cell structure in the network with reporting cell structure in mobile communication. The proposed algorithm uses a Tabu search algorithm, which is a meta-heuristic algorithm, and the proposed algorithm proposes a new neighborhood generation method to obtain a result close to the optimal solution. In order to evaluate the performance of the proposed algorithm, the simulation was performed in terms of location management cost and algorithm execution time. The evaluation results show that the proposed algorithm outperforms the existing genetic algorithm and simulated annealing.

The purpose of this study is to present basic data of basic concept that planners should consider in planning process. For this purpose, we have proposed the determinant factors of basic concept. In particular, this study focuses on the physical planning elements among the various planning elements that determine the basic concept. The research method is the case study and analysis for the competitions of LH for the past four years. After dividing the residential environment area, the planning elements was derived and the planning direction is arranged for the case district. The determinants factor were determined by the structure of each area. Three area, including the degree of urban context, were found to be the main determinants of the basic idea. The results of the study are as follows. (1) The degree of reflection of urban context, the degree of effort to resolve environmental influences are determinant factors of basic concept. (2) The degree of connection between urban and site area, the degree of overlapping of the boundaries, and street are determinant factors of basic concept. (3) The degree of appropriateness of the residential layout, the degree of rationality of the moving plan, the adequacy of the community space plan are determinant factors of basic concept.

This paper proposes a hierarchical roadmap (HRM) and its construction process to efficiently represent navigable areas in an indoor environment. HRM is adopted to solve the path-planning problems of mobile robots in indoor environments. HRM has a multi-layered graphical structure that enables it to abstract and cover navigable areas using a smaller number of nodes and edges than a probabilistic roadmap. During the incremental process of constructing HRM, information on navigable areas is abstracted using a sonar gridmap when the mobile robot navigates an unexplored area. The HRM-based planner efficiently searches for paths to answer queries by reducing the search space size using the multi-layered graphical structure. The benefits of the proposed HRM are experimentally verified in real indoor environments.
