Sharehouse has been supplied as an alternative to solving the steadily increasing one-room housing problem of single-person households every year, and it is necessary to investigate the satisfaction of residents who actually live in sharehouse through P.O.E. Therefore, this study analyzed priror researches related to the existing one-person households, sharehouses, and satisfaction surveys, and summarized indicators with high relevance and frequency to derive satisfaction survey factors that can clearly evaluate the improvement architectural plan of sharehouses. As a result, it was classified into 4 items in the 'general information' category to investigate the status, housing rental type, and housing cost of the sharehouse, 15 factors in the 'peripheral environment' category to evaluate the safety, 3 factors in the 'community' category, and 17 factors in the space (facility) and service category. In the "General Information" section, the overall one-person housing satisfaction, desired sharehouse type, housing rental type, housing cost, and living expenses were reduced. In the "Surrounding Environment", accessibility to public office, accessibility to cultural facilities, accessibility to medical facilities, accessibility to work and school, convenience stores, noise pollution and safety. In addition, in the "community" section, it consists of interactions with various people, relationships with housemates and in the "space (facilities) and service" section, heating, waterproof, soundproof, ventilation, moisture and condensation blocking, facility management, interior, room size, built-in furniture, storage space, laundry, parking. Most of the scales for each factor were 5-point Likert scales, allowing evaluation of the degree of satisfaction, and some factors presented criteria to induce structured answers. Therfore, it is expected that the survey will be conducted on residents who actually live by deriving factors for the satisfaction survey of one-person households living in the sharehouse, and the current status of the sharehouse will be identified, and the degree of satisfaction will be analyzed to be used for research.

As urbanization progresses, the demand for parks and green space is increasing. Park green spaces in the city are important spaces in the city because they are recognized as spaces where people can freely engage in outdoor activities. The park service area is a measure that shows the extent to which services are provided based on distance. In this process, the concept of accessibility plays an important role, and walking, in particular, as the most basic means of transportation for people and has a great influence on the use of parks. However, the current park service area analysis focuses on discovering underprivileged areas, so detailed evaluation of beneficiary areas is insufficient. This study seeks to evaluate park service areas based on the pedestrian accessibility and the pedestrian network. Park services are services that occur when users directly visit the park, and accessibility is expected to be reflected in terms of usability. To quantify the pedestrian network, this study used space syntax to analyze pedestrian accessibility based on integration values. The integration values are an indicators that quantify the level of accessibility of the pedestrian network, and in this study, the higher the integration value, the higher the possibility of park use. The results of the study are as follows. First, Bundang-gu's park service area accounts for 43%, and includes most sections with high pedestrian accessibility, but some sections with good pedestrian accessibility are excluded. This can be seen as a phenomenon that occurs when residential areas and commercial and business areas are given priority during the urban planning process, and then park and green areas are selected. Second, based on Bundang-gu, the park service area and pedestrian accessibility within the park service area were classified by neighborhood unit. Differences appear for each individual neighborhood unit, and it is expected that the availability of the park will vary accordingly. In addition, even in areas created during the same urban planning process, there were differences in the evaluation of park service areas according to pedestrian accessibility. Using this, it is possible to evaluate individual neighborhood units that can be reflected in living area plans, and it can be used as a useful indicator in park and green space policies that reflect this in the future.

Recently, urban mixed-use commercial facilities have been required to raise a safe environment in public areas. So, this study focuses on analyze planning factors selected through the precedent research for Pedestrian safety and environment of urban mixed-use commercial facilities. The first purpose of this study is to analyse the applicative estimation of environmental plan to support pedestrians in public space of urban mixed-use commercial facilities in Seoul. And the second purpose of this study is to propose the directions of environmental planning for creating a pedestrian-friendly environment in public space of urban mixed-use commercial facilities. In order to accomplish this purpose, the environmental planning factors for supporting pedestrians and guidelines for disabled shown in the precedent studies are drawn. A survey of research subjects are 4 urban mixed-use commercial facilities located in downtown Seoul. And then a questionnaire survey is performed on architecture and interior design students to evaluate the importance. As a result of the study, the following conclusion are drawn. The pedestrian-friendly environment in urban mixed-use commercial facilities requires planning to strengthen accessibility, supporting and safety of public space.

Construction of urban emergency shelters based on disaster-prevention green space is an important part of an urban disaster response plan. The accessibility of disaster-prevention green space is directly related to the disaster prevention service effect of green space. Taking the Jung-gu and Nam-gu districts of Ulsan city as research targets, the accessibility of three green spaces was analyzed by a network analysis method based on information regarding the distribution of population and green space and the urban road network. Two indicators for evaluating the service effect of green spaces were service population rate and service area rate. The results showed that the accessibility of the emergency refuge parks (5min) and central refuge parks was relatively good but the service area rate and service population rate of the emergency refuge parks (3min) and temporary refuge parks was less than 60%. In view of the overall situation, the service effect of disaster-prevention green space is at this point only general in Ulsan and there is great room for improvement.

This study proposes the methodology for measuring the time-distance accessibility on the Seoul bus system based on the T-card transaction databases and analyzes the results. T-card transaction databases contain the time/space information of each passenger's locations and times of the departure, transfers, and destination. We introduce the bus network graph and develop the algorithms for time-distance accessibility measurement. We account the average speed based on each passenger's get-in and getoff information in the T-card data as well as the average transfer time from the trip chain transactions. Employing the modified Floyd APSP algorithm, the shortest time distance between each pair of bus stops has been accounted. The graph-theoretic nodal accessibility has been given by the sum of the inverse time distance to all other nodes on the network. The results and spatial patterns are analyzed. This study is the first attempt to measure the time-distance accessibility for such a large transport network as the Seoul bus system consists of 34,934 bus stops on the 600 bus routes, and each bus route can have different properties in terms of speed limit, number of lanes, and traffic signal systems, and thus has great significance in the accessibility measurement studies.

Spatial information services in indoor space are an im portant application area of GIS as in outdoor space. Unlike in outdoor space, a position in indoor space is specified by a symbolic code such as room number, rather than coordinate. Therefore tracking in indoor space is no longer a prediction of coordinates but a symbolic estimation on the current position of a moving object. In this paper, we propose a framework for tracking moving objects in indoor symbolic space with RFID sensors. First, we introduce the concepts of indoor symbolic space and tracking in indoor symbolic space, and define the accessibility graph for trackable indoor symbolic space. Second, we propose a deployment method of RFID readers and a construction algorithm of accessibility graph for trackable indoor symbolic space. Third, a tracking method is proposed for moving objects in symbolic indoor space with RFID sensors. Finally, we present an implementation exmaple and the result of experiment with real data to validate the proposed method.

Ten cadavers were studied to compare the accessibility of cervical vertebral canal with conventional standard ventral slot and modified slanted ventral slot. One group performed standard ventral slot procedures at the C3-4, C5-6. The other group performed modified slanted ventral slot with inverted cone technique procedures at the C3-4, C5-6 computed tomography was performed before and after surgery. The accessibility of cervical vertebral canal with conventional standard ventral slot and modified slanted ventral slot using computed tomography in C3-4 and C5-6 intervertebral space was compared. Although smaller ostectomy was performed in the modified slanted ventral slot, some lesions were more accessible but limitations were obvious in C3-4 and C5-6 intervertebral disk space. After the disc material has been identified through accurate preoperative diagnostic imaging, less morbidity and complications can be expected if the appropriate surgical method is selected based on the lesion of compression.
