Recently, the government is pursuing to reduce the serious accidents in most industries, including the construction industry, by enacting laws on punishment. The accident rate tends to be depended on the size and type of construction sites, and the accidents occur frequently due to inadequate implementation of safety management system and management standards, especially, in small and medium-sized sites. This study has performed the profiling of 265,000 accident cases on construction sites by attribute analysis such as the ratio of days lost to work, and pattern of days lost to work compared to the size of the construction. It turned out that the proportion of accident cases was high mainly in small-scale construction sites, and long-term labor losses occurred. Shortly, it is necessary to establish an institutional standard for applying a realistic safety management cost calculation and management system centered on small-scale sites. Therefore, this study is expected to be used as fundamental data or guideline for developing a customized safety management and accident prevention system for a worker reflecting the conditions of a construction site in the future.

Daily workers in construction sites rarely receive the benefit of systematic safety and health training as they are required to move from one construction site to another in response to the start, completion, and repetition of construction works. Also, small- to medium-sized construction sites often lack the capacity to train their workers. Therefore, as in the advanced countries, basic OSH training sheme for construction workers should be conducted in the industrial-level, rather than in individual workplace-level, to make the training more effective. By doing so, only workers with the basic safety training will be able to engage in construction works. Consequently, accidents in the construction industry will decrease, as workers themselves who are at the forefront of the construction worksites are empowered to play the central role in accident prevention activities.

Purpose: The purpose of this study is to analyze the current status of disasters and initial first aid in the construction industry, and to suggest the deployment of emergency medical technicians and reinforcement of first aid training in the construction industry. Methods: Among industrial accidents in 2020, the accident characteristics and initial first aid that occurred at construction sites were analyzed, and the emergency dispatch of 119 paramedics was analyzed through the SPSS method. Results: The incidence of serious accidents was high at small and medium-sized construction sites with less than 50 workers, and the incidence of falls was high, and there were few first responders who could provide first aid in the beginning. Therefore, it is necessary to improve first aid response capabilities at small construction sites. Conclusion: In order to improve the ability to respond to first aid at construction sites, it is necessary to deploy first responders and strengthen first aid education.

공사금액 1억이상 120억 미만 중·소규모 건설현장은 전문지도기관의 기술지도를 받아야 한다. 최근 기술지도의 계약 주체가 시공자에서 발주자로 변경됨에 따라 예상되는 기술지도 부실을 방지하기 위해 기술지도 대가를 산정하는 방법을 제안하였다. 대상 건설공사를 공사금액에 따라 4개 구간으로 단순화하고, 구간별 기술지도 담당자의 일 지도횟수와 기술지도 담당자의 최소 기술 등급을 제한하고 엔지니어링사업대가를 적용하여 기술지도 1회당 대가를 산정하는 방법을 제안하였으며, 제안 방법은 설문에서 도출된 현재 형성된 일반적인 대가와 K2B 분석 결과 등을 잘 반영하므로 기술지도 대가 가인드라인 수립에 적용될 수 있다고 판단된다.

정부의 중·소형 민간공사장 안전관리 강화대책 발표에 따라 CCTV 설치 의무화 대상이 대형 공사장에서 중·소형 공사장으로 확대되었다. 하지만 기존의 건설현장의 CCTV는 안전관리를 위한 단순 관제용으로 활용되고 있어 건설현장의 모니터링을 위한 연구가 필요하다. 이에 본 연구에서는 단안 카메라를 이용하여 촬영한 단 영상을 기반으로 3개의 소실점(vanishing point)을 계산한 후 내부표정요소 정보를 포함하고 있는 카메라 행렬을 결정하고 기준 객체의 높이를 통해 대상 객체의 높이를 계산하여 정확도를 검증하는 연구를 수행하였다. 단안 카메라 기반의 소실점을 이용한 높이 결정 실험을 통해 별도의 지상기준점 측량 없이 단 영상만으로 대상 객체의 높이를 결정할 수 있었으며, 정확도를 평가한 결과 평균제곱근오차는 ±0.161m로 나타났다. 따라서, 단안 카메라를 이용하여 촬영한 단영상을 통해 건설현장의 공사 진척도를 모니터링할 수 있을 것으로 판단된다.

Recently, the issue of construction safety is growing. In the construction industry, accidents have continued to increase since 2000. In particular, the number of accident deaths at small and medium-sized construction sites accounts for 72.11% of the total number of accident deaths in the construction industry. For construction safety, prior safety evaluation systems such as Design for safety and safety management plan preparation are in place. However, at construction sites, these systems are recognized as formal legal documents, and their effectiveness is greatly reduced. Therefore, in this study, a linkage model that links design safety review information and safety management plan information was presented so that the safety management plan can be efficiently established. In addition, the effectiveness of the proposed process was verified as an example of actual work. The linkage model will contribute to improving the safety management environment at the site by increasing the productivity of safety management work by enabling easy sharing of risk factor information in the construction stage safety management work. The results of this study will be used as basic information for the development of the integrated safety management system.

인적 및 물적 피해를 크게 초래하는 건설현장의 안전사고를 효과적으로 방지할 수 있는 시스템이 절실히 필요하다. 건설현장의 안전관리 시스템은 주로 대규모 건설현장 위주로 시범 운용되고 있으나, 중소규모의 현장에서 저비용으로 운용할 수 있는 안전관리 시스템은 많이 부족한 실정이다. 건설현장의 안전사고는 예상되는 위험 지역에 허가받지 않은 작업자가 접근하지 못하도록 사전 조치를 하면 효과적으로 방지할 수 있다. 본 연구에서는 소규모 건설현장에서 저비용으로 운용할 수 있는 사물인터넷 기반의 위험구역 경보 시스템을 개발하였다. 본 시스템은 지그비 기반의 비콘기술과 셀룰러 이동통신 기술 등을 활용하여 건설현장에서 추가적인 네트워크의 구축이 없이 허가된 작업자 또는 외부인이 위험구역에 접근시에 감지하고, 안전 관리자에게 위험 경보를 즉시 통보하여 적절한 안전조치를 취할 수 있다.

This study aimed to develop a mobile separating and sorting device for discharge sites to separate and sort mixed construction waste generated in small and medium scale in small provincial cities into inorganic materials and combustible materials. The study results can be summarized as follows: 1) As a result of analyzing the existing domestic technology for the separating and sorting mixed construction waste, a device sorting the waste by fusing the vibration screen, disc screen, air blowing methods and the separating and sorting the combustible waste is applied in Korea. 2) In foreign countries, the air blowing, screen, gravity sorters are used for separating and sorting combustible waste in the same way as in Korea. Especially German T Company suggests a construction waste separating and sorting system using an optical sorter. 3) As for the test device for separating and sorting mixed construction waste to be buried in landfill, the processing capacity was set as 16 tons per day. 4) For separating and sorting inorganic materials by granularity, this study set a trommel with two types of diameter as a basic. To operate the mobile all-in-one system, the device is designed to locate a conveyor, a combustible waste conveying device, inside of the trommel. 5) The device is designed in a mobile mode under the concept of primary separating and sorting device, and it can be transported using a 2.5-ton truck minimum. The diameter and length of the trommel are designed to be within 1500mm and 3000mm, respectively. In a further study, an optimized separating and sorting technology is planned to be presented through an experimental study for processing efficiency analysis at the mixed construction waste site by manufacturing the pilot experiment facility reflecting the design elements in the result of this study.
