Current risk assessment methods typically determine accident risks embedded in construction projects by combining severity and frequency; however, they do not reflect the characteristics of construction projects. To solve the problem, this study aims to develop a novel risk assessment method that combines severity, frequency, and disaster influence factors (i.e., weather conditions and worker's characteristics) for assessing risks of activities occurring on a construction site actually. In this study, a severity was estimated by death against victims, and a frequency was estimated by the victim rate. The frequency was then converted to probability taking disaster influence factors into account. Thus, instead of considering severity and frequency for assessing the original risks (RO), the proposed method uses severity and probability to yield adjusted risks (RA) for each activity. A case study was conducted to determine if the proposed method works as intended in a real setting. The results show that RA is more sensitive to disaster influence factors than RO and, therefore, is able to assess the actual risks reflecting the working environment and conditions of a construction site. This study contributes to risk management of construction projects by offering a risk assessment method that measures a possibility of potential disasters from the probabilistic perspective. This method would help project managers assess accident risks in a more systematic and quantitative manner.

Recently, a special purpose machine with two manipulators and quadruped crawler system has been developed for rapid life-saving and initial restoration work at disaster sites. This special purpose machine provides the driver with various environmental recognition functions for accurate and rapid task determination. In particular, the human detection technology assists the driver in poor working conditions such as low-light, dust, water vapor, fog, rain, etc. to prevent secondary human accidents when moving and working. In this study, a human detection module is developed to be mounted on a special purpose machine. A thermal sensor and CCD camera were used to detect victims and nearby workers in response to the difficult environmental conditions present at disaster sites. The performance of various AI-based life detection algorithm were verified and then applied to the task of detecting various objects with different postures and exposure conditions. In addition, image visibility improvement technology was applied to further improve the accuracy of human detection.

최근 노량진 수몰사고, 방화대교 붕괴사고 등의 대규모 건설재해가 끊이지 않고 발생하고 있다. 이에 건설공사 현장에서 재해 저감을 위한 다양한 공사참여자의 역할 및 책임이 중요한 요소로 인식되고 있는 실정이다. 건설 산업은 계획, 설계, 시공, 유지관리 단계를 거치면서 발주자를 비롯한 설계자, 시공자 등 다수의 행위주체들이 참여하여 공사목적물을 만들어 가는 일련의 과정이다. 그러나 현행 안전관리의 주체는 근로자를 직접 고용하는 원도급자인 시공사에게만 책임이 집중되고 최상위에서 의사결정 권한을 행사하는 발주자의 안전활동 참여는 배제되고 있다. 이에 본 연구는 각 공사참여자를 대상으로 안전활동에 대한 인식수준 및 실태에 대하여 파악하고, 이를 통해 발주자 중심의 안전관리체계에 대한 개선방안을 제시하였다.

Purpose: Construction sites are currently facing a socialization problem as the incidence of thermal disease-related disasters increases due to summer heat waves, exacerbated by factors like the concentration of middle-aged and older workers and global warming. The reason why construction sites are particularly vulnerable to heat waves is that there are many outdoor work, which is the peculiarity of the construction industry, and most of the construction workers are elderly. This study analyzes disaster statistics of workers at construction sites for five years to investigate the occurrence of thermal diseases and analyze factors through disaster cases to provide basic data for future disasters to be reduced. Research design, data, and methodology: According to the Construction Workers' Mutual Aid Association, as of June, more than 60% of the construction workers working in the field were in their 50s and 60s. More than 24% are in their 60s and older. Thermal diseases caused by heat waves occur when exposed to high heat or strong sunlight for a long time, accompanied by headaches and dizziness. The problem is that many elderly people have underlying diseases, so if they lose consciousness, they cannot easily recover and are likely to die. Results: According to industrial accident statistics, 182 people were injured by heat-related diseases in the summer from 2016 to 2021, of which 29 died. In particular, in the construction industry, which has a lot of outdoor work, 87 people were injured and 20 people died. Conclusions: In order to prevent heat diseases caused by outdoor work, it is emphasized that exposure time is controlled, and sufficient rest and hydration are essential. Rest, water, and shade are in line with the three principles.

정부와 안전보건공단의 재해 절감을 위한 다양한 노력덕분에 산업과 건설업 전반에 걸쳐 재해 사고는 감소추세를 보이고 있다. 하지만 건설업에서의 추락재해는 감소하지 않고 오히려 증가하고 있다. 특히, 달비계에 의한 추락재해는 매년 발생빈도는 낮지만 발생 시 작업자의 사망과 직결한다는 측면에서 재해강도가 매우 크다고 할 수 있다. 국내 건설업에서의 달비계 작업환경은 매우 열악하다. 특히 소규모 건설현장에서의 달비계 작업자들은 안전에 대한 감독과 관리를 받을 수 있는 주체가 없다. 달비계 작업자들은 자신들이 직접 제작한 성능이 확인되지 않은 달비계를 가지고 불안전한 작업환경에 내몰리고 있다. 따라서 본 연구는 15년간 달비계에서 기인한 242건의 사고사례들을 분석하여 추락재해 발생 주요 원인 및 개선방안을 제시하였으며, 주요내용은 불안전한 행동에 의한 재해발생률이 높아서 작업대 안착 시, 안전난간을 넘어가는 과정, 몸의 불균형 등에서 사고가 많으며 설비개선 및 작업방법개선으로 해결이 요구된다. 또한, KOSHA Guide에서 제시하는 작업순서 상의 문제점으로 발생되는 재해는 없었으며, 다만 작업 순서를 따르지 않아 안전대를 안전대 걸이용 로프에 미설치 및 미부착에 의한 사망으로 이르는 재해가 다수 발생된 것으로 파악되어 작업방법의 개선에서 가장 중요한 사항은 수직구명줄 및 안전대의 설치 및 착용이 가장 중요한 사항으로 도출되었다.

The employment of risk management theory in Urban Disaster Management System (UDMS) has become an important trend in recent years. The viewpoint of risk management is mainly a comprehensive risk assessment of various internal and external factors, and a subsequent handling of risks. Through continuous and systematic accumulation and analysis of risk information, disaster prevention and rescue system is established. Taking risk management theory as the foundation, Organization for Economic Cooperation and Development (OECD) has developed a series of UDMS in the mega-cities all over the world. With this system as a common platform, OECD cooperates with different cities to develop disaster prevention and rescue system consisting of vulnerability assessment methods, risk assessment and countermeasures. The paper refers to the urban disaster vulnerability assessment and risk management of OECD and the mega-cities of different advanced and developed countries in the world, and then constructs a preliminarily drafted structure for the vulnerability assessment methods and risk management mechanism in the metropolitan districts of Taiwan.

Ecosystem service valuation is a crucial step for the sustainable management of watershed. In the context of various ecosystem services provided by watershed, this study, particularly deals with water yield computation in Bagmati Basin of Nepal. The water availability per population in Bagmati Basin is lowest compared to other basins in Nepal. Also, the rate of urbanization is rapidly growing over a decade. In this regard, the objectives of this study are 1) to compute the total water yield of the basin along with computation on a sub-watershed scale, and 2) Study the impacts of land use change on water yield based on CLUE-S model. For the study, Integrated Valuation of Environmental Services and Tradeoffs (InVEST), a popular model for ecosystem service assessment based on Budyko hydrological method is used to compute water yield. As well, CLUE-S model is used to study land use change, which is further related to study variation on water yield. The sub-watershed wise outcome of the study is expected to provide the guidelines for the effective and economic management of a watershed on a regional scale.
