Contemporary workspace is configured in various manners according to working patterns, collaborative or independent nature of works, group-wise working styles and culture, the size of the group, and so on. On the other hand, conventional office space has tended to be a monolithic single space packed with various types of works. This change reflects what has happened to the meanings and structures of office space. The ubiquitous computing technique is being applied to the development of the intelligent office as it grows. This leads to the change of intelligent office technology which provides user-oriented spatial service. This paper focuses on the conceptualization and design of service scenarios or the intelligent office based on the user-oriented spatial service paradigm.

This study looks at the recently increasing metaverse platform from the perspective of users. Therefore, to understand the metaverse concept as an extended space, we looked at the spatial theory and looked at the paradigm from the perspective of lifestyle and technological change. The case was viewed as 'big tech', and it was shown to be developing in various forms. simulation, Immersense, It is reclassified into Tranconnect and Explorience interfaces to suggest directions for use in various fields.

Land price contains the comprehensive characteristics of urban space, representing the social and economic features of the city. Accordingly, land price can be utilized as an indicator, which can identify the changes of spatial structure and socioeconomic variations caused by urban development. This study attempted to explore the change in land price by the road construction. Methodologically, it adopted Space Syntax, which can interpret urban spatial structure comprehensively, to identify the relationship between the forms of road networks and land price. The analytical results show that the correlation between 'integration index of Space Syntax' with 'officially assessed land price' was the highest, and as integration was higher, 'officially assessed land price' increased. Subsequently, using regression equation, it tried to predict the land price changes of surrounding areas, according to the new road construction in case area. As shown above, the research methods or study results have the advantage of predicting the changes in land price that can attract high concern of residents in an easy way. In addition, it will contribute to establishing relevant polices and smoothing business promotion through the enhancing residents' understanding by suggesting the change in land price in advance before the execution of urban regeneration and development projects.

In Korea, u-City has been constructed as IT-based new city with introduction of the ubiquitous concept. However, most currently provided u-services are just monitoring services based on the USN(Ubiquitous Sensor Network) technology, so spatial analysis is insufficient. Especially, buildings have been rapidly constructed and expanded in multi-levels, and people spend a lot of time in indoor space, so indoor spatial analysis is necessary. Therefore, connectivity relationship in indoor space is analyzed using the topological data model. Topological relationships could be redefined due to the dynamic changes of environment in indoor space, and changes could have an effect on analysis results. In this paper, the algorithms of finding isolated zones is developed by analyzing connectivity relationship between space objects in built-environments after changes of environment in indoor space due to specific situation such as fire. And the system that visualizes isolated zones as well as three-dimensional data structure of indoor space is developed to get the analysis result by using the analysis algorithms.

발코니 확장에 따른 아파트의 화재안전기준 강화를 목적으로 건축법 시행령 제 46조 제 4항의 규정에 따라 현재 건축되고 아파트에는 $2m^2$이상의 대피공간을 설치해야 한다. 그리고 대피공간은 채광방향과 관계없이 거실 각 부분에서 접근이 용이한 장소에 설치해야 하며, 출입구에 설치되는 갑종방화문은 거실쪽에서만 열 수 있는 구조로 해야한다. 하지만 현재 시공되고 있는 방화문은 비차열성 방화문으로써 거실공간에서 화재가 발생하였을 경우 방화문의 열전달 현상에 의해 대피공간 내부의 온도상승이 유발되지만 현재 방화문의 차열성능에 대한 규정이 부재하기 때문에 향후 인명피해가 우려되는 상황이다. 본 연구에서는 실제 방화문의 성능시험을 통해 대피공간과 접한 방화문 면의 온도변화를 측정하였으며, 이로 인한 대피공간 내부의 온도변화를 분석하기 위해 수치해석을 수행하였다.

최근 도시화가 급격히 진행되면서 도심 공간의 효율적인 이용을 위하여 지하공간의 개발이 새로운 대안으로 주목 받고 있다. 지하공간은 일반적으로 건축 구조상 자연채광의 유입이 불가능한 구조로서 지하 거주자의 심리적, 환경적 문제를 초래하므로 이의 활성화를 위해서는 공간의 질적 제고가 선행되어야 한다. 빛과 조명은 공간의 질을 결정하는 중요한 요소로서 거주자를 위해 건강하고 편안한 환경을 제공하기 위해서는 거주자의 생체리듬과 부합하는 자연광과 유사한 광 환경(색온도, 조도) 서비스를 제공해야 한다. 본 논문은 지하공간을 대상으로 인공조명의 광 환경을 시간의 흐름에 따라 변화하는 자연의 빛과 유사하게 서비스하기 위한 LED제어시스템을 개발한다.

This study investigates the spatial distributions of the ambient levels of air pollutants ($SO_2$, $NO_2$, $O_3$, CO, and PM) in Seoul metropolitan area using the data obtained by the air pollution observation stations. This study estimated a non-parametric kernel density function and two types of inequality indices, Gini and Entropy. Our estimation results show that the degree of inequality in spatial distribution of air pollution, in general, tends to be stable or slightly decreasing for the period of 1990~2001. In addition, we found that there are significant dynamics of air pollution levels in terms of spatial ranking.

The purpose of this study is to suggest for future public libraries in the knowledge information society. The development of Internet requires to change the role of information service in public libraries, and the change of social circumstance requires the role of public libraries as cultural spaces. For the future public libraries, the suggestions are that public libraries provide an instruction for users in order to got information through Internet. Next, public libraries provide comfortable safe, luxury space in order to create regional culture so that users can get experience high culture, and use the space as cultural living zone.

The SIFT method is well-known for robustness against various image transformations, and is widely used for image retrieval and matching. The SIFT method extracts keypoints using scale space analysis, which is different from conventional keypoint detection methods that depend only on the image space. The SIFT method has also been extended to use higher-order scale space derivatives for increasing the number of keypoints detected. Such detection of additional keypoints detected was shown to provide performance gain in image retrieval experiments. Herein, a sigma based normalization method for keypoint detection is introduced using higher-order scale space derivatives.

Government enacted "The special Law on the waterfront-space" to conduct four-river refurbishment project and to construct systematically regions around national rivers from 2009. This law allows public apartments and recreational facilities etc. to be located around four-river, then the law may give rise to serious space change and landscape damage. So we draw some problems of the established development project about the riverside area, and expected a space and landscape change of waterfront-space with a 3D simulation. The result, it is important to adjust the development density of site and apply various contents with take the regional characteristics into consideration for sustainable development.
