The characteristic of sheet metal process is the few loss of material during process, the short processing time and the excel lent price and strength. The sheet metal process with above characteristic is common used in industrial field, but in order to analysis irregular field problems the reliable and economical analysis method is demanded. Finite element method is very effective method to simulate the forming processes with good prediction of the deformation behavior. Among Finite element method, the static-implicit finite element method is applied effectively to analyze real-size auto-body panel stamping processes, which include the forming stage. In this paper, it was focused on the drawing ability factors on auto-body panel stamping by AUTOFORM with using tool planning alloy to reduce law price as well as high precision front Design Optimization of die. According to this study, the results of simulation will give engineers good information to access the Design Optimization of die.

The purpose of this study is to identify the characteristics of the community design ordinance in Seoul as view of the community design activation and to seek improvement. The findings of this study are as followings; Most of the provisions of the ordinance, such as the concept of community design, the basic plan, and the contents of the project, are defined in a similar manner. From the establishment of the concept of community design, it is necessary to establish the regulations that reflect the actual situation and characteristics of the village. In addition to physical facilities improvement, the ordinance should include support for securing space at the core center, which plays an important role in revitalizing community design. Step-by-step approaches are needed to understand the residents at the beginning of the project, because there is not enough practical support related to resident capacity and community solidarity. As the importance of the competent residents increases, the support elements related to humanware areas should also be expanded.

The purpose of this study is to propose the unit plan for home office which can substitute the existing unvaried unit plan in housing and homogeneous working space in office building through the recognition of necessity and possibility about whether home-basedworkandhomeofficecanbeformedornot. Based on the above contents of a research, the following conclusions were summarized; 1. The unit plan of home office was divided into 'jointly-used type' and 'independent-separated type' in accordance with the relationship between housing and working space, 'dwelling-emphasis type' and 'working-emphasis type' in accordance with the grade of ranks between housing and working space. And the universal validity which could accept properly the dweller's characteristics was drawn by the above classification of unit types. 2. The required characteristics in a unit plan for home office were classified into flexibility, privacy, efficiency, identity, amenity. And the analyzing system of planning methodology was assigned according to dividing interior components into space-functional, space-designing interior facts. The planning methodology would have to be considered on the correlation with each required characteristic. As a result of the study, through a planning of independent-separated type, In especial, 'vertical-separated type', it was certificated that vertical-separated type could satisfy a variety of required characteristic in space-designing as well as space-functional aspect.

The purpose of this study is to analyze the Characteristic of Block Plans related to site types of Elementary Schools in Kangju city. With analysis of 17 elementary school plans, we reached same conclusions. First, there is a possibility of seeing 4 examples that contiguity road condition and proportion of site, neighborhood park location, district units planning, which as classification the condition to feature of location. But the condition which is considered actually from Block Plan appeared with only contiguity road condition and district units planning two onlines. Second, despite there are elements having the possibility effecting to Block Plan, some arrangement forms are repeatedly used. There is a possibility of searching for that cause that it falls in mannerism of space form, type and place when it follows the arrangement form of existing defined as school.

With environmental problems and pollutions accumulated by continuous towns or cities developments events, it is becoming necessary to develop in consideration of environmental effects. This consensus leads to prepare a plan system and instrument for ecological city development, which can be a series of planning indicators. To develope a series of process for environmental friendly development, this study has three main goals as follows; development of policies and programs for environmental friendly development, suggestion of environmental friendly urban design models and standards, development of planning indicators and design guidelines Korean land use plan is operated by both zoning system and detailed plan system. But the available kinds of zoning type are too limited to apply to various and vernacular places. In addition to, the detailed plan is understood to be another regulation which constricts the freedom of building right. In this study, Plan System of Environmentally Friendly Space was studied for domestic affairs In German, Plan System of Environmentally Friendly Space is the field have been progressed before. so In this study, example of German was researched intensively, and Plan System of Environmentally Friendly Space was developed, applicable for the real state in domestic. This study was focused on methodology of landscape planning and planning for afforestation. Landscape planning is performed on condition detail investigation of existent state of nature and local characteristic, and Investigation of Planning for afforestation is more detailed than that of Landscape planning. In the basis of methodology of landscape planning and planning for afforestation, Plan for Environmentally Friendly Urban Habitation Model was developed. Plan for Environmentally Friendly Urban Habitation Model was applicable for state of land use planning. Site was selected Chuk-chun in city yang-in, taking the circumstances into consideration. So landscape planning correspond to land use planning was made out. Adjustment of Land use planning and Landscape planning was very important.
