The objective of this study is to suggest planning directions for rural landscape management and conservation. With wide literature review, the Rural Traditional Theme Village were selected as case study areas to search for the main elements according to various spatial types. The pictures taken from the site investigation were used for a questionnaire survey to understand and to find the value of rural landscape. Finally, we found out 25 items from 3 spatial type (rural life area, agriculture production area and natural environment area), and Analyzed the Preference of rural landscape elements.

A stress-strain relationship for reinforced concrete membrane elements subjected to reversed cyclic loading is quite different to that of concrete cylinder subjected to uniaxial compression. The compressive strength of cracked concrete membrane elements is reduced by cracking due to tension in the perpendicular direction. Based on the three reinforced concrete panel tests, a softened stress-strain curve of concrete subjected to reversed cyclic loading is proposed. The proposed model consists of seven stages in the compressive zones and six stages in the tensile zones. The proposed model is verified by comparing to the test results.

The design composition elements and the mechanical behavior of trusses have been investigated for Pratt trusses. As a result, it was determined that the design composition elements of the trusses consist of the composition of webs, the distance between joints, the chords profile, the depth of the truss, and the double chord composition. In addition, by analyzing models with a variation of elements, comprehensive features of structural behavior have been presented for variations of design of Pratt trusses. This is to provide more effective and useful design information on truss structure in the architectural and structural planning stage.

정부는 2021년부터 다부처 연구개발사업으로 자율주행기술개발혁신사업을 추진해오고 있다. 해당 연구개발사업에서 개발되는 자율주행차와 서비스 기술은 추후 선정된 리빙랩 도시를 대상으로 일반인들에게 제공한다는 계획이다. 특히 서비스분야는 해당 서비스별 목적과 특성에 따라 안전하고 안정적인 서비스가 가능한 공간적 범위와 운행구간을 선정하는 것이 중요하다. 본 연구에서는 향후 Level 4 수준의 자율주행서비스 제공 구역 설정 방법론을 개발하기 위한 기초 연구로서 기존 공개된 논문 및 관련 문헌조사를 통해 Level 4 수준의 자율주행서비스를 위한 정적인 ODD 구성요소를 재분류하고, 자율주행의 안전성에 미치는 공간적인 영향 요인에 대하여 Level 3 자율주행차 실제 주행데이터 및 공간정보분석 기법을 활용하여 분석하였다. 공간정보분석 기법을 통해 총 6개의 주행모드변경(제어권전환) 다발 지점이 도출되었고, 해당 지점의 중복된 정적인 ODD 구성요소 확인 결과 자율주행의 안전성에 영향을 미치는 요인은 횡단보도, 신호등, 교차로, 자전거 도로, 포켓차로, 주의 표지판, 중앙분리대로 나타났다. 이러한 공간정보분석을 통한 자율주행의 공간적 요인분석은 자율주행기술개발혁신사업의 리빙랩 도시뿐만 아니라 현재 확대·운영되고 있는 자율주행차 시범운행지구에서 자율주행서비스 운영지구 선정에도 기초연구로 활용될 것으로 기대한다.

Korean cities need sustainable urban regeneration based on the effective application of space and resource. Especially a sustainable urban regeneration needs the activation of community in the urban underground space as urban development center. The purpose of this study is to propose elements and factors of spatial planning of community in urban underground space for sustainable urban regeneration and to propose the characteristics of spatial planning of community in urban underground space according to strategies of sustainable urban regeneration. The research methods of this study used to conduct research include precedent study reviews and survey. The conclusions of this study are as following; The application of various factors related to spatial planning aspect of communication, supportive cultural facilities, accessibility and nature is needed for creating a sustainable urban regeneration. Especially, in urban underground space, the application of spatial planning for community activation considered strategies of sustainable urban regeneration should be necessary. And introduction of cultural facilities, multi-dimensional pedestrian network for accessibility and natural elements for activating community in urban underground space are needed for making sustainable urban regeneration.

In the face of the new dimension of the developed technology $L{\acute{a}}szl{\acute{o}}$ Moholy-Nagy, a master of 'the Bauhaus Akademie', made an effort to constitute the integrated life of the intellectual and the emotional by translating the experiences of the new technology Into the emotional language and the cultural realities. As an artist who criticized in the constructivist ethos the conception of the image as the imitation and brought the Image movements into relief Moholy-Nagy groped for a new expressive idea that can be called as 'the idea of the non-representational spatial expression' in which the expressive elements interact one another. His idea of the non-representational spatial expression that is made up of the pure forms of the nature, the direct colors and the spatial elements is oriented to incorporate the modern realities, i.e. the space experiences as the complicated sensory workings and the new technology as the measure of the human thinking, and further to see where they will move to. This study is on the one hand purposed to explicate the fundamental idea of the non-representational spatial expression that was poorly illuminated in spite of its importance in the respects of the design and art history, on the other to re-actualize the implications of the space-design which are contained in it.

This paper studied the spatial factors activating the personal interaction based on case studies of $M\'{e}diath\'{e}ques$ in France. The spatial factors are analyzed into material factors and dematerial factors. The material factors have physical features in space and directly or indirectly activate the personal interaction. They consist of 8 elements including pocket space, balcony, atrium, stairs, elevators, windows, conference rooms and furnitures. The dematerial factors consist of 6 elements including polycentrism, continuance, mixture, interpenetration, dematerialization, transparency. They are compounded of material factors and explain them conceptually. But dematerial factors are abstract concepts. To provide reliability I confirm the relationship with dematerial factors by using a connections, topology, a phased depth of the Depthmap as the framework of the visual recognition of the space syntax covering the characteristic of dematerial factors. The result of the quantitative analysis human-behavior in $V\'{e}nissieux$ $M\'{e}diath\'{e}que$ and the result of applying the spatial factors of $M\'{e}diath\'{e}ques$ as the community center to the $V\'{e}nissieux$ $M\'{e}diath\'{e}que$ proved that the spatial factors are significant factors of the $M\'{e}diath\'{e}ques$ as the community center.
