The bearing wall apartments which occupy the majority of multi-residential apartment buildings built in Korea, are known for having limited architectural plan flexibility, posing challenges in terms of maintenance and remodeling. The economic losses and environmental issues resulting from the reconstruction of bearing wall apartments are now accumulating to the extent that they are becoming a national concern. Multi-residential apartment buildings, which are now the dominant form of residence in Korea, must accommodate diverse customer needs and changes in life style. A new concept of Rahmen structure with architectural flexibility is Green Frame. GF multi-residence housing is expected to reduce construction costs and shorten the construction schedule by overcoming the shortcomings of conventional bearing wall apartments. This goal is consistent with the national policies that target the reduction of resource and energy consumption. In addition, GF will be established as a core contributor to achieving a reduction in $CO_2$ emissions, which will enable the sustainable growth of domestic construction industry, and address the low-carbon green growth drive implemented by the government.

This paper is a study on the implementation of a sensor-based smart compression system for improving home and street environments. Since modernization, the amount of garbage has been increasing every year, and this has seriously adversely affected not only people but also ecosystems such as marine pollution and soil pollution. In particular, in large cities with large floating populations, garbage is dumped on the streets without proper measures to deal with the amount of waste generated. In order to improve this problem, this paper intends to implement a system with automatic compression and opening/closing functions using sensors. This system is designed to activate automatic opening/closing function through an infrared sensor, and automatically opening and closing when the inclination is changed using an impact sensor. In addition, by installing a distance sensor, the amount of internal waste can be easily monitored from the outside, and a manual compression switch and a manual opening/closing switch is separately designed to enable opening and closing and compression as needed to increase the effectiveness.

In this paper, we examined the development of Chinese Taoist architecture, its cultural implications, and comprehensively summarized the core principles of the Taoist ecological ideas that are reflected in Taoist architecture. This is a groundwork for exploring an ideological model for sustainable ecological architecture in modern cities. Taoist architecture has a long history that has led to changes, developments, and a gradual maturation. Zhi (治), Lu (廬), and Jing (靖), were the first architectural forms of the early Taoist body. These formed the basis for the future development of Taoist Courts (宮觀). The state-sponsored government-run Taoist Courts established from the time of the North and South Dynasties to the time of Tang Dynasty led to a constant standardization of the rites, and these Courts gradually became more and more formalized. Since the establishment of Quanzhenjiao (全眞敎) in the early 12th century, a movement that emphasized putiy training, architecture for the ascetic practice emerged in remote natural spaces suitable for strict ascetic practices. Meanwhile, in Taoist architecture, the type and structure of buildings were strengthened in order to worship various gods. The various Taoist Courts established through this historical process embody the elements, institutions, and ecological ideas of Taoist culture. Taoist architecture basically pursued the idealism of Paradise in a Deep Cave (洞天福地) and adopted a feng-shui theory of using natural terrain artfully in selecting a place and building a layout. This was reflected through their ecology. Meanwhile, Taoist architecture does not destroy the balance of nature by emphasizing the utilization of local natural resources whenever possible while selecting building materials according to the principles of yinyang and the five movements (陰陽五行). In addition, Taoism aims to select simple places for practising asceticism and ancestral rituals whenever possible because of the need to maintain a simple mind, suppress desire, and return to a state of purity. This attitude is an indication of a kind of simple ecological ideas and value of frugality easily found in Taoism. The ecological ideas of Taoism provide abundant resources for considering solutions to the ecological crisis that arises in the creation of residential environments. Through the ecological ideas of Taoism, we can find a direction to understand the relationship between human beings and nature while creating new, sustainable residential environments.

This study used three types of temporary shelters, tents, and prefabricated houses provided by the Chinese government for victims after the Wenchuan earthquake in 2008 as case study objects. Through literature review, 12 evaluation items were selected from the social, economic, and environmental elements of the sustainability of residential space design to analyze and evaluate three types of temporary shelters, and derive their respective characteristics and problems. The analysis results show that the temporary centralized settlements and tents had problems such as imperfect infrastructure, poor sanitation, narrow living space, no personal space, and inconvenience in life. Prefabricated houses had problems such as high construction costs, non-environmentally friendly building materials, occupation of arable land, low recycling rate of materials, and environmental pollution by waste. The common problem of the three types of shelters was that the government took the lead in the construction and distribution of shelters, and the disaster victims passively accept government support. Therefore, disaster victims were not actively involved in the construction and management of temporary communities. Secondly, the designs of all three types of temporary shelters did not fully consider the psychological needs of the victims, especially the need for safe and hygienic personal space. Finally, this research proposes improvement plans for the problems in the sustainable design of three temporary shelters and the construction and management of temporary communities.

이 논문은 우리 환경의 생태계 보호를 위하여 뉴 디자인 가구가 어떻게 창조되고 있는지를 연구하였다. 즉, 오늘날 포스트 모던 시대에 뉴 디자인 가구 디자이너들이 환경 문제의 해결점의 하나로 새롭고 다른 방향으로 자신들의 가구를 창조할 수 있는가에 관한 담론이다. 우리가 안고 있는 생태계 보호를 위한 가구를 디자인할 때 필요한 재사용 및 재활용이 가능한 재료들, 유행을 초월한 가구, 가구의 견고성, 대량 생산 가구 등이 심각하게 분석되었다. 이 분석에 따르면 뉴 디자인 가구 디자이너들은 재활용된 재료들, 주거 환경 및 지속성, 새로운 가구 미학을 내포한 새로운 가구 디자인 철학을 얻을 수 있었다. 대량 생산된 가구는 경제성 때문에 많은 대중에게 접근되는 좋은 점보다는 우리에게 더 많은 쓰레기 더미를 준다라는 사실이 뉴 디자인 가구 다자이너들에게는 매우 심각한 문제였다. 따라서 가구 디자이너들이 양보다는 질에 중점을 둔 가구를 창조하는 것이 필요하다는 것이다. 결론적으로 환경적 책임을 느낀 뉴 디자인 가구 디자이너들은 튼튼하면서 재활용될 수 있으며 유행을 초월한 기능적이면서도 미적인 가구를 창조할 때만이 뉴 디자인 가구론 구입하는 소비자들이 뉴 디자인 가구를 올바른 방향에서 인식할 수 있을 것이다.

최근 지속적인 출산율의 감소와 평균수명의 증가로 인하여, 대한민국의 초고령 사회는 예상보다 훨씬 빠르게 증가하고 있다. 핵가족 형태가 보편화되며 1인 가구도 함께 늘고 있어서 홀로 사는 노인의 수 역시 증가하는 추세이다. 주거 공간에서 낙상사고와 같은 고령화 안전사고가 많이 발생하고 있다. 혼자 사는 독거노인들의 경우 사고 발생 즉시 대처가 가능한 보호자가 없다는 문제점이 있다. 본 논문에서는 MediaPipe를 이용한 낙상사고 감지 시스템을 개발한다. 먼저, 이 시스템은 MediaPipe를 이용해서 카메라를 통해 실시간으로 수신된 영상에서 사람을 인식하고, 자세 유형 분석을 통해 낙상사고 발생 여부를 판별하여 애플리케이션을 통해 보호자에게 현장 상황을 알려주는 시스템이다. 낙상사고가 발생했다면 보호자용 애플리케이션을 통해 사고 발생 알림 및 현장 사진을 보여준다. 이와 같은 기술을 활용하여 응급상황에 처한 노인을 빠르게 구조하며 독거노인의 생활안전사고 문제를 해결하는 데에 기여하고자 한다.

Currently, China's urban space is gradually changing from gradual development to inventory transformation. The planning and development goals of urban communities have also shifted from material space construction to the direction of sustainable development of humanities and society. Currently, community planning and construction at a single latitude, which focuses on residential life, overlooks the multidimensional elements of community life production, causing many problems such as cold relationships between communities and difficulties in forming relationships between humans and the environment. Therefore, this article re-recognizes the sociality of the community in the continuous unification of the community in time and space, clarifies the central and private aspects of the community, and re-explores the dynamic creation and methods of the community as the starting point of daily life.
