개방형 사무실 건물에서, 총 환기량이 적정할지라도 국부적으로 환기가 부족하거나 또는 과다한 작업공간들이 존재할 수 있다. 이것은 환기시스템을 설계할 때 작업공간의 배치와 관련된 정보를 활용하지 않기 때문이다. 모든 작업공간이 충분히 환기될 수 있도록 하기 위해서는 급기구나 배기구 그릴의 형태나 배치선정 등과 같은 다 양한 설계변수들이 작업공간의 HVAC 시스템의 성능에 미치는 영향을 파악하여야 한다. 본 원고는 최근 수행된 작업공간의 환기 성능에 관한 연구결과를 요약한 것이다.

In this study, we the characteristics of the spatial layout have been analyzed focusing on the case of compulsory schools, which are the forms of elementary and middle integrated schools in Japan. Thus, according to the development stage of the elementary·middle students, we derived the characteristics of the space structure and layout of the classrooms of each class. and derived spatial arrangement of private and shared space of elementary and middle integrated schools. In addition, we analyzed the characteristics of subject classroom collaboration by beginner, intermediate and advanced level, derived a desirable subject classroom placement plan, and suggested the basic direction of Korean elementary and middle integrated schools focusing on the direction of space layout composition.

This study covers museum rest areas among the methods that reduce museum fatigue. The subjects of the study were Seoul branch of the representative National Museum of Contemporary Art and National Museum of Korea. These museums were compared and analyzed with The National Art Center of Tokyo and Tokyo National Museum. The first research step was the analysis of museums' floor plan, and the second step was the tracing survey of visitors' movement. The result of this study was as follows. The National Art Center of Tokyo and Tokyo National Museum had the rest space within the visitors' route along with good viewing areas. National Museum of Korea had poor viewing area even though there was the rest space withing the visitors' route. Lastly, Seoul branch of National Museum of Contemporary Art had the rest space out of visitors' route along with poor viewing areas. This study is meaningful in that it provided guidelines for museum space plan with visitors' route considered, so that their museum fatigue can be relieved along with the guideline that can be applied to space elements of rest space.

본 논문에서는 색채에 대한 아동의 심리를 분석하기 위해서 CRR(Colour Reflection Reading) 및 주조색를 이용한 심리 분석 기법을 제안한다. CRR은 이미 그려진 그림에 아동이 색을 칠하는 것으로 색이 칠해진 데이터를 바탕으로 아동의 심리 상태를 분석한다. 주조색 심리 분석 기법은 원하는 색을 선택하여 그림을 그리고, 그린 그림을 이용하여 심리를 분석한다. 따라서 본 논문에서는 퍼지 논리를 적용하여 색채에 대한 심리 분석 결과를 도출하고 그린 그림을 기반으로 공간 배치도 분석 기법을 이용하여 공간 배치도에 따른 아동의 심리 상태도 분석한다.

The requirement for customized learning environments is increasing with the development of Web 2.0 technology To personalize services in E-learning, there are various functions available to the user. However, some components have fixed or inflexible functionality that limits what can be changed, and customization information has not been used for other purposes. In this paper, we propose an e-Space manager for the dynamic customization of learning environment control units. The proposed method can confirm which areas users have customized and how they have customized them. The advantage is that users can control their own learning environments, including not only the format, but also the content within the limits of the underlying system. The customization information is captured to confirm the competency model.

The primary school library make high using convenience of teachers and students and support work of teachers efficiently because of transmission education and information fundamentally. Generally, the main purpose of space composition is economic Lay-out of space and furniture to connect faculty of between space and space. Therefore, to convenient for users and high effect of education, Lay-out of space and furniture, we survey and analyze Lay-out type of faculty space in primary school library. To this aspects, the purpose of this study is to understand state and analyze the occupancy character of space for students that user of primary school library then when we plan primary school library, accomplish more efficient space plan that specialization, pluralistic, individuality of primary school library and cope with environment of education and change of society actively.

In order to display various art works such as media art in a multi-display environment, it is necessary to consider contents arrangement. The advantage of having a 1: N or N: N layout instead of a 1: 1 or N: 1 layout between display and content, but a more complex scheme of how to do spatial and temporal layout in multi-display Is required. In order to distribute contents, existing media server solution or programming-based multimedia production software is used. However, it takes much time to rearrange or modify the contents, and it is not easy to modify the contents. Therefore, It is difficult to place content in the environment. In order to solve this problem, various approaches are needed from research on content placement method to development of content placement software that improves the existing method. However, analysis on systematic content placement type supporting it, or interface There is also no access to. In this study, we have summarized the requirements for designing the interface for each type with the aim of making it possible to utilize previously analyzed content layout types in various display activities such as media art in multi - display environment. The requirements of each type of interface were derived based on spatial arrangement and temporal layout type which are most distinguished when content is placed. The contents of the interface requirements are summarized as follows: We expect to be a cornerstone for system development.

In this paper, we consider node deployment algorithms for the sequence-based localization (SBL) which is recently employed for in-door positioning systems, Whereas previous node selection or deployment algorithms seek to place nodes at centrold of the region where more targets are likely to be found, we observe that the boundaries dividing such regions can be good locations for the nodes in SBL systems. Motivated by this observation, we propose an efficient node deployment algorithm that determines the boundaries by using the well-known K-means algorithm and find the potential node locations based on the bi-section method for low-complexity design. We demonstrate through experiments that the proposed algorithm achieves significant localization performance over random node allocation with a substantially reduced complexity as compared with a full search.

In this paper, we propose an extended reality-based simultaneous multi presence system in a process of remote cooperative work. The proposed system generates a ring-shaped invisible screen which surrounds a user, and it provides position and manipulation of remote workspace and personal workspace. With the proposed system, the user easily navigates the several workspace for the remote collaboration or he/she selects a specific space for immersion. The proposed system also provides manipulation of personal workspace for the user during the remote cooperative work. We conducted a user study to prove effectiveness of the proposed system. According to the results, the proposed system increased understanding spatial information and usage of time during the remote cooperative work.

Curing recent years, several state-space models describing discrete two dimensional systems are proposed. In this paper, we consider the problem of pole assignment of two dimensional systems using state feedback, based on state-space model proposed by Roessser. The design procedure is seperated into two steps. in thie first step, the sufficient condition for off diagonal matrix of the input transformed system to be zero is derived and in the second step, it is shown that the pole assignment problem of two dimensional systems is divided into the one of two 1-dimensional systems. Finally, a numerical example for illustrating the technique is given.
