The current aging population calls for more facilities to care for the elderly. Recently the average life span of Korean has been lengthened. The percentage of the old over 65% which was 5.7% in 1995, is expected to be increased to 12.5% in 2020. Therefore, the social problems of old people occur in various aspects nowadays, and will become more serious in the near future. This study will provide basic planning guidelines in designing of the dementia ward of the Special Hospital, and the purpose of this study is to suggest a model of the utilization of Special Hospitals.

In this paper, a new intelligent moving target tracking and surveillance system basing on the pan/tilt-embedded stereo camera system is suggested and implemented. In the proposed system, once the face area of a target is detected from the input stereo image by using a YCbCr color model and then, using this data as well as the geometric information of the tracking system, the distance and 3D information of the target are effectively extracted in real-time.

지금까지 우리나라의 GIS는 국가 중심의 GIS로, 사용자들이 적극 참여하거나 민간 산업 부분으로 확대되기에는 기술력, 비용 등의 한계를 갖고 있었다. 그래서 우리는 Open Source를 이용하여 종래 GIS의 한계를 극복하고 Google Map, Google Earth, Sketch Up을 연동한 Web Portal Site 구축을 통하여, 사용자들이 의사결정을 하는데 도움이 되는 효율적인 정보를 제공하며 이들이 곧 정보 창출의 주체가 되는 쌍방향적인 참여를 이끌어내고자 한다.

The aim of this study was to detect landslide using satellite image and apply the landslide to probabilistic landslide-susceptibility mapping at Gangneung area, Korea using a Geographic Information System (GIS). Landslide locations were identified by change detection technique of KOMSAT-1 (Korea Multipurpose Satellite) EOC (Electro Optical Camera) images and checked in field. For landslide-susceptibility mapping, maps of the topography, geology, soil, forest, lineaments, and land cover were constructed from the spatial data sets. Then, the sixteen factors that influence landslide occurrence were extracted from the database. Using the factors and detected landslide, the relationships were calculated using frequency ratio, one of the probabilistic model. Then, landslide-susceptibility map was drawn using the frequency ration and finally, the map was verified by comparing with existing landslide locations. As the verification result, the prediction accuracy showed 86.76%. The landslide-susceptibility map can be used to reduce hazards associated with landslides and to land cover planning.

Size of building has a direct relationship with building cost, energy use and space maintenance cost. Therefore, minimizing building size during a project development is of paramount importance against such wastes. However, incautious reduction of building size may result in crowded space, and therefore harms the functionality despite the fact that building is supposed to satisfactorily support users' activity. A well-balanced design solution is, therefore, needed at an optimum level that minimizes building size in tandem with providing sufficient space to maintain functionality. For such design, architects and engineers need to be informed accurate and reliable space-use information. We present in this paper a conceptual framework of an agent-based space-use prediction simulation system that provides individual level space-use information over time in a building in consideration of project specific user information and activity schedules, space preference, ad beavioural rules. The information will accordingly assist architects and engineers to optimize space of the building as appropriate.

The purpose of this study is to research the influence of soundscape in the preference of landscape. Specifically, Standards types of communications are applied to the landscape such as artificial waterscapes and natural valley. The spatial image was analyzed by the variables of Kaplan´s information processing model. The level of visual preferences was measured by a type of acoustic information in landscape and media of communication, and these data were analyzed by multiple regression. The results of this study can be summarized as follows; The value of landscape preference was not different from all fluent of coherence, complexity, legibility ,mystery and preference utilized the communication media, but it was different by the type of acoustic information in landscape. These results clearly show the influence of sound affecting decisions of landscape preference. The factors determining the level of landscape preference were found to be coherence, complexity, legibility, mystery and dummy variables of acoustic information in landscape and media od communication. These variables amy be the major factors which must be considered on planning and designing as the functional basis for the quantitative analysis.

In this study, the independent variables are the floor plan configulation. The dependent variables are the occupant's egress behavior, especially spatial movement pattern, and life - safety performance of building. Fire events were simulated on single story of office building. Simulation run for allowable secaping thime(180 seconds) arbitrarily selected, and involved 48 occupants. The major findings Pre as follows. 1) Computer simulation model suggested in this study can be used as the Preoccupancy evaluation method of the life-safety performance for architectural design based on prediction of occupants' egress behavior in the levels of validity and sensitivity, 2) Sucess or failure in occupants' escape is determined by decreasing walking speed caused by jamming at exits or over crowded corridor, and increasing route length caused by running about in confusion at each subdivision and corridor. 3) In floor plan configuration which safe areas located at the extreme ends of the corridor, cellular floor planning have to be avoided preventing jamming and running about in confusion at overcrowded corridor.

In this paper, we introduce a reinforcement learning-based algorithm for personalized tourist path recommendations. The algorithm employs a reinforcement learning agent to explore tourist regions and identify optimal paths that are expected to enhance tourism experiences. The concept of tourism experience is defined through points of interest (POI) located along tourist paths within the tourist area. These metrics are quantified through aggregated evaluation scores derived from reviews submitted by past visitors. In the experimental setup, the foundational learning model used to find tour paths is the Deep Q-Network (DQN). Despite the limited availability of historical tourist behavior data, the agent adeptly learns travel paths by incorporating preference scores of tourist POIs and spatial information of the travel area.

Community facilities in most rural villages have many problems in the aspect of their size or functions as well as they are generally too superannuated to support diverse community activities; which results in a low degree of inhabitants' satisfaction with community facilities, and inconvenience for using them. Therefore, it may carefully be said that it's time to need the established studies that are necessary with consider to community facilities which can reflect inhabitants' diverse activities. In this study, 5 places which the most common events among the major monthly events of total 25 rural villages were held were selected as the subject place for survey; and then investigated, by means of the participant observation method, the using behavior of inhabitants who used community facilities. Focusing on size, factors, and layout that were being faced by community facilities in most rural villages, This study investigated the number of users, the characteristics of traffic line and behavior, and the using behavior by group; through considering their correlation with the physical setting of community space, it deduced the problems of use; and it proposed the direction of improvement on the basis thereof. Therefore, this study will serve in the future as useful basic materials for designing a rural village's community facilities in consideration of size, factors and layout which can appropriately support inhabitants' community activities.
