현대 사회는 모든 분야에서 다양한 분야들의 기술들이 융합되는 사회이며, 이로 인해 각종 환경적 위험 요소 등이 존재한다. 그중 한가지는 유해 가스에 의한 피해이다. 산업이 발전하고, 편의 시설등이 늘어나면서 다양한 시설들이 설치되고 있다. 하지만 이와 함께 시설물들이 가지는 위험도 또한 높아지고 있다. 이에 본 연구에서는 센서를 이용한 위험요소 탐지와 환경측정 자료를 기반으로 일상 생활에 접할 수 있는 위험요소를 파악하고 개선하고자 하였다. 진행은 유해성분을 측정할 수 있는 센서를 이용한 시스템을 구성하고, 자료 분석을 통한 개선사항를 도출하는 방식을 취하였다.

Purpose: Traditional markets often have irregular space utilization patterns because the spaces are created and divided as time passed. Internally, there is high risk of fire due to problems such as aging facilities and high-density of stores and externally, there is high risk of fire spread since it is often adjacent to deteriorated residential and commercial facilities. Method: In this paper, on-site investigations were carried out to check fire risk factors and fire spread risk, and fire occurrence and expansion risk factors were investigated for traditional markets in Hwanghak-dong and Dong-daemun by using large-scale fire data from existing traditional markets. Result: As a result of the analysis, there are likely to be various problems such as high fire load and lack of safety awareness due to aging facilities and high-density of stores. In particular, it is necessary to prepare countermeasures because deteriorated residential facilities with narrow alleys around traditional markets have high fire spread. It is situation that while traditional markets mainly are managing for fire and disaster centering on the merchant association, the surrounding residential areas are not properly managed. Conclusion: It is necessary to manage deteriorated residential facilities with traditional markets, also to be linked early warning system and information to evacuate rapidly in case of fire there.

This research aims to investigate the alterations in typhoon patterns attributable to climate change and to quantitatively assess the risk of damage to residential structures. The increasing prevalence of climate anomalies and severe weather events, a consequence of global warming, is causing escalating damage globally. Notably, numerous countries are facing substantial devastation due to shifts in typhoon trajectories. Despite this, there exists a gap in empirical research quantifying the impact of these changes on building integrity and the associated risk alterations driven by climate change. In addressing this gap, our study analyzes the frequency and intensity of typhoons impacting Korea, examining the evolution of these meteorological phenomena. Furthermore, we employ the Korean Typhoon Vulnerability Function for residential facilities to quantify the altered risk posed by these changing patterns. The outcomes of this study provide the private sector with essential data to formulate diverse scenarios and business strategies in response to the escalating risks of typhoon-related damage. Additionally, it equips governmental bodies with the necessary insights to develop comprehensive risk management strategies to mitigate the effects of future typhoons.

The purpose of this study was to investigate the effects of home modification in the community care project on the fall risk environment and the health condition in elderly people aged 65 and over. HOME FAST and WHODAS-K 2.0 were used to evaluate, and it was conducted as a group pre-post experimental study. As a result of implementing the home modification service based on the assessment, the fall risk level showed a statistically significant decrease (p<.01), and in the case of health condition, mobility (p<.01) and social participation (p<.05) was confirmed that it was statistically significantly improved in the domain, showing a positive change in the overall health condition (p<.05). In the future, research using a comprehensive home assessment is needed for more subjects. and a process of selecting subjects prior, expansion of professional manpower infrastructure to providing a quality service is required.

Architecture is the historical record of a society. Residential culture is one of the cultures, and includes all the living and customs of people living in the current society. In particular, the Native residence has the research value of changing the living culture because it contains the lives of farmers. The residential culture of the Korean-chinese people contains the poor, agricultural, and immigrant life that began as a livelihood. Therefore, residential culture is an important part of the Korean-chinese culture. However, due to population movement and urbanization, the deepening and aging of the rural community caused the destruction of the residential culture, and the residentials that had been vacant for many years were destroyed, and a large number of risky residential reconstructions are underway. At the point of progress from a voluntary personal building culture to a public building culture built by the government, a study on Renovation of dilapidated Building and a more reasonable residential reform plan is needed. Our housing culture should not only improve the living environment of current life, but also inherit the housing culture contained in history.
