Due to the development of construction technology, there is a considerable increase in the number of skyscrapers in the world. Accordingly, there are rapid growing requests about maintenance systems such as cleaning, painting, and monitoring the processes of facade in highrise buildings. However, it is extremely dangerous working the walls of high-rise buildings, and crashes from buildings have accounted for large proportion of constructional accidents. An alternative solution must be developed with the commercialization of automatic robot systems. For the last decade, interest in developing robots for cleaning and maintenance in facade of highrise buildings has continuously increased. The use of automatic robot systems can be expected to reduce accidents and decrease labor costs. In this paper, we propose a new kind of cleaning mechanism. We have designed and manufactured various cleaning tools for different types of facades with economic commercialization. The cleaning cycle, size, and intensity will be determined by economic constraints as well. The final goals are to design and manufacture tools and robots that can clean facades efficiently and rapidly even in dangerous places. The cleaning tool systems consist of nozzles, brush rollers, and squeezing devices. Furthermore, these tools and robots perform each process utilizing the systems of built-in guide types and gondola types for building maintenance. The performance of the proposed cleaning tools is evaluated experimentally; however additional study should be necessary for safer and more stable commercialization.

본 논문에서는 관람자가 스마트 기기를 활용하여 프로젝션 파사드의 영상을 컨트롤하는 시스템을 제안한다. 한 관람자가 아닌 다수의 관람자가 동시에 파사드에 매핑된 영상 콘텐츠에 접근이 가능한 시스템이다. 이를 활용한 작품 'Design of Social Projection Facade'는 프로젝션 매핑 영상과 스마트기기의 연동 기술을 기반으로 한 다중 관람자 참여형 미디어파사드 시스템 실험 작이다. 파사드 하나를 대상으로 한 관람자들의 공동 창작이 아니라 네트워크 시스템을 통해 물리적으로 떨어진 파사드 간의 인터랙션 및 연결, 콘텐츠 공유, 다중 관람자 참여라는 점에서 기존 연구와 차별화된 인터랙티브 시스템이라 할 수 있다.

As residents and building owners demand maintenance that is required to achieve sustainable building performance, efficient building management methods are required. Even though the demand for maintenance systems is increasing, current maintenance work for high-rise buildings mostly uses conventional ropes and gondolas that pose a high risk of accidents and exhibit poor performance and efficiency. Thus, there is an urgent need to develop an automation robot system that can reduce accidents and improve the maintenance efficiency of the conventional high-rise building façade maintenance system. As a preceding work for the development of an automation robot system, this study classified and analyzed the work processes of actual construction sites and proposed basic techniques for the work mechanisms of the robot system by investigating the motions of cleaning workers.

Laboratory buildings with specialized equipment and ventilation systems pose challenges in terms of efficient energy use and initial construction costs. Additionally, lab spaces should have flexible and efficient layouts and provide a comfortable indoor research environment. Therefore, this study aims to identify the correlation between the facade of a building and its interior layout from case studies of energy-efficient research labs and to propose passive energy design strategies for the establishment of an optimal research environment. The case studies in this paper were selected from the American Institute of Architects Committee on the Environment Top Ten Projects and Leadership in Energy and Environmental Design (LEED) certified research lab projects. In this paper, the passive design strategies of space zoning, façade design devices to control heating and cooling loads were analyzed. Additionally, the relationships between these strategies and the interior lab layouts, lab support spaces, offices, and circulation areas were examined. The following four conclusions were drawn from the analysis of various cases: 1) space zoning for grouping areas with similar energy requirements is performed to concentrate similar heating and cooling demands to simplify the HVAC loads. 2) Public areas such as corridor, atrium, or courtyard can serve as buffer zones that employ passive solar design to minimize the mechanical energy load. 3) A balanced window-to-wall ratio (WWR), exterior shading devices, and natural ventilation systems are applied according to the space programming energy requirements to minimize the dependence on mechanical service. 4) Lastly, typical laboratory space zoning categories can be revised, reversed, and even reconfigured to minimize the energy load and adjust to the site context. This study can provide deep insights into various design strategies employed for construction of green laboratories along with intuitive arrangement of various building components such as laboratory spaces, lab support spaces, office spaces, and common public areas. The key findings of this study can contribute towards creating improved designs of laboratory facilities with reduced carbon footprint and greenhouse emissions.

The purpose of this study is to identify the characteristics of the use of the western building system with the change of the architectural design in the Japanese colonial period focused on the facility built by Joseon Government-General in 1910s. Through the 131 cases of governmental building, the tendency of the use of western building system. After 1910, Japanese Imperialism adopted the western wooden building system which main structure was made with combination of small pieces of timber for building the modern governmental facility because of the political and financial intention. So, all facilities were designed similarly by the structural module and the facade was finished by the feather boarding in the same with the 'sitamitakei-giyohu' in Japan. the functional requirements of each facility was not revealed. Such an western wooden building system was used until 1920s with the change of the facade by the mortar coating. But, in 1920s-1930s, the building system have begun to change. The use of the brick system caused some changes although the planing concept was still lasted. On the other hand, the use of the reinforced concrete led to more changes on the overall scheme.

Educational environments in rural areas have been slowly deteriorating due to the popular flow of people moving into the city from the countryside. It has been concluded that superannuated educational facilities have a negative influence towards students. This research has been conducted in order to give better mental or psychological influence to those around and comfort and relaxation to the students themselves through developing new ways to renovate the $fa\c{c}ade$ of the run down educational facility. This research develops several structural and ecological (environmental friendly) elements which are used as several segmental elements of the new $fa\c{c}ade$ design for the degraded educational facilities. A combination of these design elements can develop many viable alternatives of a new $fa\c{c}ade$ renovation. These new renovations can help students to maintain their educational and social lives in a safer and more ecological environment.

Double-Skin Facades (DSF) on tall buildings are becoming increasingly common in urban environments due to their ability to provide architectural merit, passive design, acoustic control and even improved structural efficiency. This study aims to understand the effects of porous DSF on the aerodynamic characteristics of tall buildings using wind tunnel tests. High Frequency Force Balance and pressure tests were performed on the CAARC standard tall building model with a variable porous DSF on the windward face. The introduction of a porous DSF did not adversely affect the overall mean forces and moments experienced by the building, with few differences compared to the standard tall building model. There was also minimal variation between the results for the three porosities tested: 50%, 65% and 80%. The presence of a full-height porous DSF was shown to effectively reduce the mean and fluctuating wind pressure on the side face of the building by about 10%, and a porous DSF over the lower half height of the building was almost as effective. This indicates that the porous DSF could be used to reduce the design load on cladding and fixtures on the side faces of tall buildings, where most damage to facades typically occurs.

As the contemporary times entered, the attention focused on the 'human's perception on a space' as much as on that a space's physical structure, so the meaning of a space became defined depending on how a person thought over and behaved in the space. As this age is the times of consilience and integration, a space accepts new technologies beyond being defined simply based on the space's structure and its shape and tries to provide different, 'strange experiences' from tho se felt by the human until now. Recently in the filed of space design, it can be seen that the spae design's connection with various technologies affects on considerable influence on the all fields of culture and arts like space marketings, media arts, exhibitions and performances as well as the buildings. Especially. the fusion of digital images and architecture is actively developed. Images possessing the moving light's attributes shine a city night and day and a building changes a city's appearance itself by adding new materials on the surface of building. It is the purpose of this study to study what new experiences the human gets and creates from his interaction with spaces based on such technological fusion. By studying some cases that used the digital media as a mediating instrument as the way presenting spatial experiences to the human, this study intended to identify what design factors were applied and to find appropriate directions for space desig in relation to what new trials can be done.

융통성 있는 소프트웨어 개발을 위해 많은 객체지향방법론들이 제공되어 지고 있으나, 이러한 객체지향방법론들은 자동적으로 재사용을 제공하거나 건실한 소프트웨어 시스템을 만들지 못하고 있다. 따라서 이러한 객체지향 방법론들은 개발자에게 상세한 설계지침을 제공하지 못하고 있으며, 분석·설계자들로 이런 문제점들을 인정하고 방법론들을 향상시켜 나가려고 노력하고 있다. 이와 같이 분석·설계자들의 노력을 줄여 주면서 설계단계의 정보를 재사용할 수 있도록 제공하고자 하는 것이 설계패턴의 개념이며, 이러한 설계패턴과 객체지향 방법론은 상호 보완적인 관계를 가지면서 시스템을 개발하는데 유용한 설계 길잡이의 역할을 한다. 이에 본 논문에서는 객체지향 방법론 중에서 가장 많이 다루어지고 있는 OMT 방법론과 Gamma가 제안한 설계패턴 중 Facade, Mediator, Observer의 세 가지 설계패턴에 대한 상호작용을 보여주고, OMT방법론 내에 설계패턴을 적용함으로써 구체적인 설계지식과 재사용에 대한 명확한 해법을 제안한다.
