The megalopolis citizens are reevaluating the expectant value and the perception of leisure aceording to increasing the level of their incomes, The leisure of citizens is increasing in the aspect of quantity and quality of life nowadays In the site planning of leisure, the concrete understanding about people's choice of a leisure site will be the most important thing, not only for the aspect of improvement of the quality of life but also efficiencies of the land use The purposes of chi study are firstly, to find out the factors which are influenced on a choice of Outdoor leisure facilities in neighbourhood unit and to Compare the Characteristics Of Choice models between the three metropolitan areas, secondly, to predict a limitation of use areal according to the change of a needed time based on the metropolitan's standard choice model For the choice model establishment this research used Logit Model which has been used in the field of the traffic, the tourism and the economics. This research made the results which find out the influencing variables with needed times, the accessibility and the percentage of facilities. The lindtations of use areas come out the results which are predicted according to the change of needed times as a most influencing factors. The range of each preferred leisure facility is about 956 meter distant in the neighbourhood park about 644 meter distant in the pocket park about 604 meter distant in the recreation center, about 628 meter distant in the tennis court about 974 meter distant in the private hob by facility and about 528 meter distant in the library from the apartment unit The recreation center and the library are nearer facilities than the other facilities. But these facilities are surveyed to be more or less influenced by an interesting progran, a context of events and the level of useful facilities, etc.

To find out the status of document delivery and interlibrary loan services and the use of information technology in special libraries, questionnaires were sent to 328 special Libraries nation wide with at least 1 librarian, listed In the Korean Libraries Statistics 1994-1995(1996). $46.6\%$ were returned and 152 Questionnaires were analyzed. For document delivery, $61.3\%$ use BLDSC$47.5\%$ use KINITI. 87 libararies $(57.2\%)$ participate In interlibrary loan activities. To send requests, FAX and telephone is used the most, while FAX and print copy is used the most to receive the requested documents. $45-75\%$ use various information technology including online databases, Internet, e-mail, etc., and the use of information technology was related to the budget of the libraries. The costs, budgets, and slowness was the problems raised by the most. To improve the document delivery services, the most urgent thing is establishing cooperative system using BBS or Internet. Network systems to facilitate interlibrary loan should be established ultimately.

The subject heading is an elaborate access tool for subject browsing and searching in information retrieval environment. The purpose of this study is to suggest the applicable facets to subject headings in Korea. First, the concepts of subject and the definitions of facets were investigated in the literature review. Second, six cases including OCLC's FAST, PRECIS, "Thesaurus construction and use", CC $7^{th}$ edition, BC $2^{nd}$ Edition, and UDC $3^{rd}$ Edition were analyzed to focus on configuration of facets as case studies. Based on the results, twenty-two facets were proposed including Topical, Event, Geography, Chronology, Personal and Corporate Name, Title, Form, Genre, Language, and Person facets as 11 top facets. Also, Topical-Thing/Entity and Topical-Action/Status, Part, Kind, Property, Whole, Material, Patient, Product, By-Product and Agent facets as sub-facets of Topical facet.

In this paper, we propose a system which can detect the flame in real time from the high-quality IP camera. First, open directly the RTSP streams transmitted from the IP camera using the library FFmpeg as opening a video file. The second thing is to extract the background images from video signal using Gaussian mixture model. Then the foreground images are obtained through subtracting operation between the input image and the background image. Separated foreground image through a mathematical morphology operation are considered as candidate area. By analysing colour information and dynamic characteristics of the candidate area, flame is determined finally. Through the experiments with input videos from IP camera, the proposed algorithms were useful to detect flames.

The leisure demands and the interests for the quality of urban residents have been increased, but the leisure space is absolutely deficient. In the leisure site planning, the concrete understanding about people's leisure site choice is the most important thing, not only for the aspect of the leisure demands reception and the improvement of the life quality but also the aspect of the efficiency of land use. The purposes of this study are firstly, to find out prefered leisure sites, secondly, to establish the choice models of the each prefered leisure site to be substituted for existing indiscriminating leisure space planning. And for the choice model establishment, we used Logit Model, which has been used in the Traffic, the Toursim, the Economics fields. We extract people's perfered leisure sites in Seoul through 1st and 2nd survey, those are a park, a pocket park, a play hall, a recreation center(sport center), a hobby facility, a library. The established choice model for each prefered site can predict people's choice about 70 percents correctly. It indicates that the Logit model is useful for the explanation about the choice of residents in the urban area. Specially, the main affect factors to the choice of each prefered leisure site are different. It means that different consideration factors or different standards are needed for each leisure site planning.

The purpose of this study is to identify and systematize various facet elements required by users in fiction search situations from book tags to improve the fiction search environment. Based on the Ranganathan's PMEST formula, the basic facet system of the fiction was defined as 1) the personality that forms the fiction material, 2) the content and external characteristics that compose the fiction, 3) the reader interaction with books, 4) spatial information related to fiction and reading activities, and 5) time information related to fiction and reading activities. Out of approximately 310,000 tags assigned to 7,174 fiction, 3,730 core tags were selected and content-analyzed. As a result, various attributes were systematized around the top 25 categories of the fiction facets. The results of this study can be applied to facet navigation of OPAC and fiction DB in the future.

As a software component for computer game, the physics engine simulates objects' movement according to the laws of physics. This paper introduces a design and implementation of mobile game on the Android platform, where we used JBox2D physics engine library and Android graphics APIs. We borrowed the key idea of this game from Crayon Physics which is known as a famous PC game. This game starts with no way from user character to destination character. The game user has to make a way to destination character from user character by creating polygon objects between them. The user wins when user character meets destination character. However, the game user has to decide the time to create objects and their shapes well because all objects in this game are governed by the laws of physics. As an important thing of this paper, we introduced into this game new input methods of LCD touch and sensors embedded in mobile devices but not in PCs. Game users can create objects by drawing polygons with LCD touch and move objects or characters according to sensor values from accelerator sensors by tilting the mobile device.

This study aims for the above mentioned. After all, through the analysis of Electronic Question/Answering Function to understand a user's demand under online circumstances, groping for the method to provide an appropriate Archival Information Service is the most important thing. For this, in this study, it researched the users interviews and the research related to users as a precedence study, and the studies having examined the state of demanding information by users through analyzing the e-mail actually. Additionally, by looking over the study of Library and Information Science that is activated in a field of Electronic Question/Answering Function rather than Archival Science, as a matter of fact, the study has come up with the standard for analyzing Electronic Question/Answering Function. And based on the precedence study, the instances for the National Archives from USA, England, Australia and Canada were analyzed, and the chance of activating Archival Information Service were tried to grope for in the study. This study might be one of methodologies in examining the users study that is not activated yet in Archival Science. Therefore, the users study can be carried out in various methods as well as Electronic Archives/Answering Service. This study might be the important information in providing far better Archival Information Services. It is desirable that based on this opportunity, the study related to the various users by examining not only Electronic Archives/Answering Function but also Question/Answering of the users and the Archivists in the filed to the larger extend will be activated for Archival Science.
