Recently, the concern of aging society is 'Healthy life' for the elderly and pre-elderly. Especially, realizing the 'Healthy life', it is very important for the elderly to establish living environment for holding and maintaining mental depression. Mental depression is related to dysfunction of sensory organ included physical functions. Therefore, the dysfunction of elderly's sensory organ is required to the guideline of environmental planning. In this study, among five senses, I focused visual sense due to the large proportion of environmental perception. The purpose of this study is to analyze the degree of geriatric depression and preference of simulated images applying preferable color for the elderly. This study conducted literature review and questionnaire survey. Firstly, the previous studies related with the melancholy, sense of isolation, self-regard for the elderly analyzed. Secondly, the questionnaire tool measuring the degree of geriatric depression developed. Thirdly, the tool investigating the preference for the simulated images applied main, sub, and accent colors produced. Applied preferable colors were used from the results previous study. Lastly, based on the result, the basic data of color planning were suggested. It was judged that this study is an useful as the basic guideline of color planning for the elderly's residential spaces and the potential value of considering geriatric depression and the color planning in terms of the elderly's visual sense.

Potential and capabilities of GIS in planning and decision-making is widely known as an experimental tool, but its existence in real-world application is yet to realize. GIS originated in the field of cartography and even at today it is mainly used as a tool for map production. Number of reasons could bring forward for this shortcoming. Limited real-world applications could be a significant one among them. This paper describe an attempt to use GIS technology in Lao PDR where a study team was involved in formulating a Master Plan for national healthcare system. A database was created for the whole country with spatial and descriptive data gathered from various sources. Attempt was made to demonstrate the potential of GIS by using the database for identifying healthcare status, distribution of resources, recognizing deprived areas and locating areas for future investments based on accessibility and social status. The approach justified the investment on a GIS system and introducing the system in the planning sector from grass-root level to central level.

This study deals with roughing planning by cross sectional information generated from sculptured surfaces. Bicubic Bezier surface is adopted as sculptured surfaces in this paper. The system consists of 3 pstyd : 1) modeling sculptured surface, 2) reconstruction of cross-section in 2D coordinates, 3) determination of roughing tool path with structural data. The system is developed by using BIM-PC in the environment of Auto CAD R11, AutoLISP and MetaWare C. The proposed system shows an efficient algorithm for roughing planning with cross sectional information.

The main purpose of this paper is to define the concepts and measures of accessibility used in various disciplines. To do this, a significant literature review was conducted particularly in fields of traffic engineering, transportation planning, urban economics, urban planning, and geography of transportation. The result indicates that each discipline uses the concept of accessibility in a slightly different perceptual framework and thus shows somewhat ambiguous definition. The result also indicates that accessibility should serve as a tool to integrate transportation planning into the other connected disciplines.

In this paper we propose a Genetic Algorithm for the path planning of an autonomous mobile robot. Genetic Algorithms(GAs) have advantages of the adaptivity such as GAs work even if an environment is time-varying or unknown. Therefore, we propose the path planning algorithms using the GAs-based approach and show more adaptive and optimal performance by simulation.

In this research uses a predetermined initial weight vectors of 1-dimensional string, gives the systematic input vector whose position best matches obstacles, and trains the weight vectors such that neurons within the activity bubble are moved toward or reverse the input vector. According to simulation results one can conclude that the modified neural network is useful tool for the global path planning problem of a mobile robot.

This research suggests that the Design Quality Indicator for School(DQIfS) could be applied on the education facilities construction process not only as a building design assessment tool, but also as a participation tool. From the analyze of the background, the aims, the implementation processes and the case studies of the DQIfS, the results are: 1. DQI was formulated with the social requirement for the public participation in the public building design processes.; 2. DQI was articulated with the aim to involve the wide range of the stakeholders in the design processes, to hear the various opinions of the stakeholders, and to apply these opinions in the planning or the decision-making processes.; 3. In the implementation stage, it was found that the implementation methods of the DQIfS was devised to involve the wide range of the stakeholders. Moreover, the DQIfS has transformed its representation way to convey the results to the stakeholders and make a base for the discussion. 4. Through the case studies, it was found that the DQIfS was used with various participatory planning methods in the implementation process. Furthermore, the DQIfS was used as a main method to provide the basis of the discussion about the educational facility design. Thus, it could be concluded that DQIfS is a specialized participation tool for making participatory processes in the educational building design processes.

Among the mainstream of this society has quickly adopted computer technology as part of their daily life, the ever growing group of elderly people, which will increase from 7% of the population in 2000 to being 14% just 18 years later, has been being exposed to computer using environment more than ever before. According to the survey of Korean government in 2005, the number of the elderly using computer has been rising actually, so web-based survey to identify housing needs of the elderly seems to have lots of possibilities as a useful tool for them. This study aims at comparing web-based survey tool with paper-based one, developed to identify the elderly needs on digital home planning. Experimental method and in-depth interview were employed. The participants were divided into 2 groups, web-based and paper-based survey group. Each group was controlled over by age (average 60 years old), gender and computer skill. As a results, web-based survy tool was revealed as effective to clearer understanding and causing more interests and more available, but less easy to handle than paper-based survey one. Through the in-depth interview, web-based survey tool was identified as a more effective method to figure out the needs of the elderly who are familiar with computer.

As consumer's desire becomes various, agility of mold manufacturing is the most important factor for competitive mold manufacturer. Decision making process is required to produce optimal result of CAM systems in using commercial CAM system to generate tool path. The paper proposes a methodology fur computer-assisted tool selection procedures for various cutting type of rough, semi-rough and finish cuts. The procedure provides assistance for machining tool selection by analyzing sliced CAD model section of die cavity and core. Information about machining time for the generated NC-code is used to aid the tool selection. The module is developed with commercial CAM API. This module will be used fur the optimization of tool selection and planning process.
