The Intelligent Space(ISpace) provides challenging research fields for surveillance, human-computer interfacing, networked camera conferencing, industrial monitoring or service and training applications. ISpace is the space where many intelligent devices, such as computers and sensors, are distributed. According to the cooperation of many intelligent devices, the environment, it is very important that the system knows the location information to offer the useful services. In order to achieve these goals, we present a method for representing, tracking and human following by fusing distributed multiple vision systems in ISpace, with application to pedestrian tracking in a crowd. And the article presents the integration of color distributions into particle filtering. Particle filters provide a robust tracking framework under ambiguity conditions. We propose to track the moving objects by generating hypotheses not in the image plan but on the top-view reconstruction of the scene. Comparative results on real video sequences show the advantage of our method for multi-object tracking. Also, the method is applied to the intelligent environment and its performance is verified by the experiments.

This paper presents and analyzes urban planning process to be adopted to create ubiquitous space in city environment, using City of Seoul's Digital Media Street Project as a case study. The Digital Media Street will become the main pedestrian thoroughfare in the Digital Media City (DMC) in Sangam area, planned to become the world's first ubiquitous environment in full urban scale. Ubiquitous space is reinterpreted from an urban planning perspective, and a new approach to planning such a space is introduced, including strategies to couple technology, space, and human activities. Methodology, role of different actors, planning process, and institutional arrangement are examined in turn, and this yields further agenda for improvements that can be made in planning ubiquitous spaces in the future.

Freiburg, as the German Capital of the Environment, is well known to Koreans, and relationships with Korean cities are deeply extended. This study attempts to grasp the features of the historical and cultural environment in Freiburg's old town center pedestrian district through the investigation of the historical value of environmental elements and the way they are transmitted along with the components of city identity. Through the literature studies confirms that. The main canal in Freiburg, called Gewerbeknale, is valued both for its existence during the city construction period and for being an infrastructure to supply water to the Bachle(small urban canal) and Brunnen(fountain). In spite of a recipient environment in the middle of the 19th century, the traditional mosaic pavement has a new value as an mediator between citizens and the environment through the adaptations that have occurred in the city. This study has verified the dialectical repetition of crisis and conquest through the historical succession of environmental elements. The historical continuance of environmental elements has a strong influence on the acquisition of sameness and Individuality in city identity factors. The result of this study recommends the historical value of environmental elements that have survived in the urban environment, and verifies the necessity of a concrete strategy for preservation and related practical efforts.

Recently, the prediction of wind environment around a building using Computational Fluid Dynamics (CFD) technique comes to be carried out at the practical design stage. However, there have been very few studies which examined the accuracy of CFD prediction of flow around a high-rise building including the velocity distribution at pedestrian level. The working group for CFD prediction of wind environment around building, which consists of researchers from several universities and private companies, was organized in the Architectural Institute of Japan (AIJ) considering such a background. At the first stage of the project, the working group planned to carry out the cross comparison of CFD results of flow around a high rise building by various numerical methods, in order to clarify the major factors which affect prediction accuracy. This paper presents the results of this comparison.

The purpose of this study is to suggest some alternative on site planning of elementary school through investigating the effects of geographical and urban environment on the site. For this, we selected and surveyed 35 schools in Gwangju. The results of this study are as follows. 1) We cannot find out the differences from the use of elementary schools sites on slopes of sites. However, the sunken space between H type buildings in the site slopes facing east or west and the placing the playground on the north side of the site slopes facing north have some problems 2) The number of adjacent road and surrounding environment didn't show any effect. To separate between cars and pedestrians, we need some plans to block cars on the pedestrian gateway and it is much better to intensify the parking area near the school gate that cars come in and out. 3) The degree of satisfaction on the outdoor facilities of these cases shows low level. Therefore, to use the site of schools efficiently, we should secure the spacious playground and make plans to provide some spaces around school building for the static activities of students and teachers. 4) Most of all, the site which is suitable for educational environment should be selected. and also Special Code on the urban plan should be established to develop this one.

In the planning process, there are five directions to planning residential sites. Firstly, the site must be planned to allow continuity with the city space, or created to conform to the city structure. Secondly, plans for community space and programs as well as convenience facilities must coexist in the road space. Thirdly, in terms of view, the site must be planned in territories to secure identity of the site. Fourthly, in terms of the environment, the site should utilize the natural environment. Lastly, in terms of infrastructure, the site should include a pedestrian-centered road system as well as establishing city infrastructure facilities for a combined planning in the municipal dimension. So far we have looked at planning methods for an apartment site that can be integrated into the existing city. The study into five elements to planning a large-scale apartment site, context, community, landscape, environment and infrastructure, and their relationship among each other must continue on.

The study aims to figure out the problems of Daldongnae (hillside shantytown) in Jaman-dong, Jeonju, and to propose the countermeasures for village regeneration. Based on the survey of current conditions in the area and the case study of successful regeneration projects, this study suggests regenerating concepts for the community. The study on the current state analyzes that Jaman-dong is faced with the population decline, especially among the young, the lack of community facilities and infrastructure, and the unfavorable situation in the residential environment. The case study involves three successful Daldongnae regeneration projects: the culture-based regeneration of Cultural Village (in Gamcheon-dong, Busan), the regeneration focused on healthcare and education of Ibagugil (in Choryang-dong, Busan), and the community-led regeneration of Rainbow Village (in Dae-dong, Daejeon). The regenerating concepts for the community are as follows: utilizing the existing local community center as a gathering place for the residents, furnishing a cultural space for a growing number of visitors, adding new parking space, installing convenient facilities in order to provide better pedestrian environment for the disabled and elderly, improving street landscapes, and establishing citizen participation programs.

Recently, with a high level of economic growth, rapid urbanization, population, environment and housing problems were accompanied in Korea. In particular, the traffic problem has become a serious social problem. As the current transportation policy has been carried out, concentrating on traffic flow, in 2015, death rate for pedestrians while walking (1,795 persons) is 38.8% compared to entire death rate in car accident (4,621 persons), so there is need to solve it. Although, crosswalk should make pedestrian cross it safely, it has been made on the basis of the width of road without exact standard for current width of the crosswalk and the location of stop line. Moreover, in the area around many campuses or commercial facilities, crosswalks are set with not considering pedestrian passage, but designed uniformly. Therefore, the purpose of this study is to estimate reasonable dimension of crosswalk considering pedestrian traffic and walking speed and it makes the accident rate lower in the crosswalk, which has a lot of problems including decisions of vehicle traffic signal time, lack of pedestrian's signal timing, pedestrian's crossing of long-distance. The following are the methodology of the study. Firstly, for crosswalk calculation of specifications, examination relating existing regulations and researches dealing with crosswalk, pedestrians and stop line is needed. After analyzing problems of current width of crosswalk and stop line, present the methodology to calculation of specifications and basing on these things, calculation of specifications for crosswalk will be decided. In conclusion, the calculation of specification and improvement of stop line for crosswalk laid out in this study are expected to be utilized as base data in case of establishing relevant safety facilities and standards.
