This study analyzed and investigated problems of local safety experience halls' spatial structure and media status. Improvements would be suggested after comprehending the need to execute safety education based on citizen's satisfaction and requests. Contents of safety experience space concept, display characteristics and types applied to local institution were analyzed. Safety experience centers with systemized protocols that opened after 2003 and were bigger than $5,000m^2$ were selected. We had three candidates and they were Seoul Gwangnaru Safety Experience Center, Boramea Safety Experience Center and Daegu Safety Theme Park. Going through checklists and interviewing official institutions that were in charge of safety hall educations helped comprehension of sample space status and detailed experimental presentation media. A survey was created based on this study and was distributed to users and non-users of safety experience halls. The survey consisted of general questions covering situations, awareness, level of interests, frequency and satisfaction level. The results were extracted with SPSS 18.0 through frequency analysis and cross tabulations. This research improvements through synthesized contemplation. For the resuits First, various experimental programs need to be supplemented in order to prevent accidents. Second, vivid experimental spaces need to be planned for active participation and users should be fully aware of safety hazard through education. Third, there weren't enough institutions compared to the education needs. Promoting and building more safety experience halls are dire. Finally, these suggestions of the results will be distributed in the planning of the exhibit hall.

The purpose of this study was to investigate the spatial characteristics of residential and nursing units in large skilled nursing facilities for the elderly that were located in city areas, and to discuss the way for efficient unit care. For collecting the data, the researcher visited 6 facilities to make explorations and to interview the staff concerned. Most of the research facilities had systematic residential units that each unit basically had elderly private rooms and the spaces for small group. The number of elderly residents per unit was appropriate for the limit which was suggested by Kwon(2002), but the sizes of small group spaces were smaller than the standard limit($1.62m^{2}$ per resident). The nursing units were made up of nursing station, 2-4 residential units, spaces for large group of residents, hair dressing, nurse, living assistants, bathing, storage and etc. Some of them had problem in efficiency of space use because they did not have distinct usage. In conclusion, this study suggests that each floor has one nursing unit including 40 residents maximum and each nursing unit consists of 2-3 residential units that have 20 residents maximum per unit. In each residential unit, the furniture and spaces for efficient unit-care should be arranged, such as TV, dining table, kitchenette, bathroom, and rooms for living assistants. The hall type is better for the small group so that it has a transitional characteristic leading to the public spaces. The large group space needs to have clear usage such as conducting program differentiated from small group, and various furniture such as sofa, TV, table, and etc which encourage the elderly voluntary use.

The research made a study of the spatial characteristics of $m\'{e}diath\'{e}ques$ based on the twelve case studies of the BMVRs constructed with the financial support of the government since 1992 in France. The $m\'{e}diath\'{e}que$ is the community center for local residents to collect information, to have relationship with others and to shape public opinions. Thus it should have easy accessibility, liberal flow plan and the diversity of the newest information. The architectural elements to offer these faculties are summarized as follows. Firstly, the $m\'{e}diath\'{e}que$ as the public facility should have the easy flow plan and the high recognition for visitors. Second, it should be the efficient space for both managers and visitors. thus, it should not need more managers or have the difficulty to move. Third, it should be planed to support the change of the form of information and the needs of the visitors. It, therefore, should have the wide space with no wall and divide the space by movable furnitures. Lastly, it should be the space with the natural light, and it does not need the special artificial lights like museums. It is considered that the planning of the $m\'{e}diath\'{e}que$ should be from the four principles. Additionally, the program of the $M\'{e}diath\'{e}que$ should reflect the each local traits.

Diagnostic display monitor QA according to AAPM TG18 is usually performed by PACS administrator, product manager and reading doctor, and for acceptance testing and periodic quality control evaluation, a combination of visual and quantitative tests can be used, as outlined in sections 5 and 6 of 'assessment of display performance for medical imaging systems'. Although many display tests can be performed visually, a more objective and quantitative evaluation of display performance requires special test tools. The required instruments vary in their complexity and cost, depending on the context of the evaluation(research, acceptance testing, or quality control) and how thorough the evaluation needs to be. Objective and reliable assessment of many display characteristics can be performed with relatively inexpensive equipment, So, we made 'AAPM TG18 guiding instrument' to ues variable purpose of the evaluation of 'geometrical distortions(quantitative"', 'veiling glare(visual)' and 'sensor calibration'. The spatial measurements for the quantitative evaluation of geometric distortions, and the measurement of the veling-glare ring response function which provides information regarding the spatial extent of the luminance spread, can be performed using the TG18 guiding instrument can be used to sensor calibration to standardize the basic rate of 0% luminance when periodic calibration.

Due to development of modern medical services and economics, people raised expectation and demand about medical services from previous disease treatment to comprehensive health care covering prevention and health care. Responses of each medical facility to these social needs and the evolution of concept of medicine rapidly occur. The health examination centers are being operated with the purpose of health examination and this trend is reflected on several aspects such as the size of the facilities, function and configuration of space in health examination centers. Thus, health examination centers consisting of various space systems appear, but this trend and interpretations are lacking. Therefore, the purpose of this study is to draw trends of system through analysis of types and its evolved space systematic analysis and establish it. Analysis targets were classified into small, medium and large groups by sizes based on number of space and a total of 12 health examination centers in four for each category were selected. As research methods, functional relationship of space was examined through analysis of type in which segmentalized type tools were applied in local units. The flow diagram was established based on direction turning point and was classified into sub-flow and main-flow in local units and the systems between local units were derived. Finally, the results of this study can be summarized as the following three results. 1) The space connection system of health examination center showed four systems such as circulation, independence, continuation, and network. 2) Local type indicators and global type indicators which were evolved more from limitation of type analysis tools in existing research were derived so that more systematic analysis could be made. 3) Network system is distributed approach system and space for each function is formed around public space.

A panoramic video which supports to make viewers feel an immersion through fitting to a wide field of view (FOV) larger than the human visual angle needs an interactive viewing method such as selecting targeted view point among widely viewing points of a panoramic video because it difficult to simultaneously view a whole panoramic video due to a limited viewing environment and bandwidth. When a user officially uses a view navigation in order to select a view point, it happens waste of resources such as bandwidth owing to the transmitted video data of unnecessary view points. Therefore, this paper proposes the spatial-temporal prediction filter (STPF) which is based on the direction and velocity of the view navigation for transmitting only the necessary video data. As a result of simulation, STPF reduces bitrate saving rates by from 6% to 37% compared to conventional methods in the interactive panoramic video streaming service required high bandwidth.

Web on Web 2.0 paradigm is regarded as a kind of platform. Accordingly, users on web can use almost same applications like using certain applications on personal computer, to given purposes. For Web as platform, it needs web-based or web-recognizable file format to communicate or to exchange various information contents and data among applied applications. Text-based JSON is a practical format directly linked Javascript on Web, so that XML-typed data, being previously built, can be possible for tagging process containing JSON format. However, GeoJSON handling geo-spatial data sets is now fledgling stage in standards. Thus, it is not on the practical applicability level, and there are a few tools or open sources for this format. To adopt GeoJSON for the future Geo-web application, users implement GeoJSON parser or apply the server-based open source GIS for their purpose. In this study, a preliminary work for GeoJSON application in Geo-web service carried out using Google Maps API and openlayers library API.

Image fusion is defined as making new image by merging two or more images using special algorithms. In case of remote sensing, it means fusing multispectral low-resolution remotely sensed image with panchromatic high-resolution image. Generally, hyperspectral image fusion is accomplished by utilizing fusion technique of multispectral imagery or spectral unmixing model. But, the former may distort spectral information and the latter needs endmember data or additional data, and has a problem with not preserving spatial information well. This study proposes a new algorithm based on two stage spectral unmixing model for preserving hyperspectral image's spectral information. The proposed fusion technique is implemented and tested using Hyperion and ALI images. it is shown to work well on maintaining more spatial/spectral information than the PCA/GS fusion algorithms.

This study investigates the effectiveness of Jeju's public Wi-Fi policy for which the key factors of public Wi-Fi use and location characteristics are analyzed. Spatial regression analysis was conducted within a 100 m radius of public Wi-Fi access points. In the analysis, the dependent variable was public Wi-Fi usage time while independent variables included demographic factors, location factors, and other factors. The findings reveal that demographic factors such as the number of residents, the number of workers, and the number of visitors had a close correlation with the use of public Wi-Fi. In addition, the number of bus stops and land prices of each parcel, land use mix, and AP installation period had a positive correlation with the use of public Wi-Fi. On the contrary, the number of buildings by use, the total floor area of buildings, and the number of tourist attractions had negative correlations with public Wi-Fi usage time. These findings provide policy implications that more active publicity on Jeju's public Wi-Fi is needed and the convenience for access needs to be improved.
