In this study, an integrated 3D modeling and rendering system dealing with 3D urban landscape features such as terrain, building, road and user-defined geometric ones was designed and implemented using $OPENGL\;{|}\;ES$ (Embedded System) API for mobile devices of PDA. In this system, the authoring functions are composed of several parts handling urban landscape features: vertex-based geometry modeling, editing and manipulating 3D landscape objects, generating geometrically complex type features with attributes for 3D objects, and texture mapping of complex types using image library. It is a kind of feature-based system, linked with 3D geo-based spatial feature attributes. As for the rendering process, some functions are provided: optimizing of integrated multiple 3D landscape objects, and rendering of texture-mapped 3D landscape objects. By the active-synchronized process among desktop system, OPENGL-based 3D visualization system, and mobile system, it is possible to transfer and disseminate 3D feature models through both systems. In this mobile 3D urban processing system, the main graphical user interface and core components is implemented under EVC 4.0 MFC and tested at PDA running on windows mobile and Pocket Pc. It is expected that the mobile 3D geo-spatial information systems supporting registration, modeling, and rendering functions can be effectively utilized for real time 3D urban planning and 3D mobile mapping on the site.

Many fractal objects observed in reality are characterized by some irregularities or complexities in their features. These properties can be measured and analyzed by means of fractal dimension. However, in many cases, the calculation of this value may not be so easy to utilize in applications. In this respect, we have treated a formal method to estimate the dimension of fractal curves.

This paper proposes a Expert CAPP System for integrating CAD/CAM of rotational work-part by rule based approach. The CAD/CAPP integration is performed by the recognition of machined features from the 2-D CAD data (IGES) file. Selecting functions of the process planning are performed in modularized rule base by forward chaining inference, and operation sequences are determined by means of heuristic search algorithm. For CAPP/CAM integration, post-processor generates NC code from route sheet file. This system coded in OPS5 and C language on PC/AT, and EMCO CNC lathe interfaced with PC through DNC and RS-232C.

Day care center for the elderly is an alternative for community care for frail elderly who need social participation and physical cares and services outside the family. The purpose of this study was to identify the present situation of day care center for the elderly and to suggest desirable interior space plans for elderly day care center. Data were collected by two ways; a mail survey and case studies of existing day care centers. Five cases of day care centers were analyzed to find out Physical and space problems, available programs and services. Also, the staffs in 96 day care centers for the elderly in nationwide were selected for a mail survey and 68.8 percentage of all was collected and analyzed. From the result of case studies, narrow space and lack of accessibility features for wheelchair or other prosthetic devices were the major problems. From the result of a mail survey analysis, the elderly users were over 73 years old, and high proportion had suffered from dementia and apoplexy Also, staffing ration was 1:7 In other words, one staff was caring of 7 old people, and supporting staff was insufficient. Therefore, supportive, therapeutic environment Was more important issue to improve quality of care. Separate program room and outdoor space, lounging space, treatment room by gardening, separate counselling room, bedroom, a simple kitchen unit, staff office, separate physical treatment room, resting room for staff was indicated more necessarily. When priority of planning interior space was safety followed by accessability and convenience, it was also reported that sire of each room was generally narrow. The most serious problem in interior space was the lack and narrowness of space, and accessible features for mobility. Based on the literature review and the findings of this study, two types of floor plans for elderly day care center were suggested;‘a mixed type for the elderly with and without dementia’and‘a separate type for the elderly with dementia.’The main goals for designing interior space for two types of elderly day care center were to provide safe environment, encouraging environment for remaining abilities of users, sanitary environment, therapeutic environment, familiar environment, and socially-encouraging environment. The recommendations for further studies were suggested.

The major purposes of this study were to analyze main features of US Green Building Council's LEED for Homes rating system and examine residents' satisfaction on their LEED-certified homes and neighborhoods. The first part of this article shows the structure and features of the LEED for Homes rating system and the process to obtain credits of this rating system. The investigation to assess residents' satisfaction targeted LEED certified home residents in Midwest in the United State. The satisfaction was assessed in relation to socio-demographic and housing characteristics. To collect data, a quantitative survey was administered to the residents of LEED-certified homes in Midwest in the US. A total of 605 surveys was sent out and 235 were collected, yielding a 38.8% response rate. Findings revealed that LEED-certified home residents were highly satisfied with their homes and neighborhood although neighborhood satisfaction was lower than housing satisfaction. Residents' income and education were the significant socio-demographic factors that show significant relationships with housing satisfaction. Residents' home ownership, length of residence, housing types were significant housing characteristics on their satisfaction while the levels of LEED certifications (i.e., certified, silver, gold, and platinum) were not significantly related to housing satisfaction. The findings of this study suggest the importance of developing effective strategies for those who are less educated, lower income classes, renters, or multi-attached housing residents for more successful development of LEED-certified homes in the future.
