In the past, measures for the reduction of industrial accidents has led the safety and health policy of construction sites by the guidance, supervision and the regulation according to「Occupation Safety and Health Act」handled by Ministry of Employment and Labor (MOEL). Nowadays companies realize that due to the factors such as diversification of employment types, outsourcing of hazardous work, new construction method and complicated types of construction, etc., there is a limit on safety management for construction sites as far as it is passively led by the governmental safety management policy and regulation. In this study, in order to practice the autonomous safety management escaping from the government-led safety management, improvement plans are proposed and applied by analyzing the basic cause of the all kinds of fall accidents that could possibly occur in the apartment construction sites and by verifying the hazardous factors and risks by fields.

2018년 여름의 폭염은 기상관측을 시작(1907년 10월 1일)한 이래 111년 만에 가장 높은 기온을 기록하였는데, 서울은 39.6℃를 기록(2018년 8월 1일)하여 종전의 기록인 38.4℃(1994년 7월 24일)를 뛰어넘었다. 열섬현상으로 인해 도시의 온도가 상승하고 하절기 열쾌적성이 저하됨에 따라 하절기 열환경 개선에 대한 연구가 지속적으로 진행되고 있다. 본 연구의 목적은 조경공 사 전·후의 온도저감 및 외부공간 이용자가 느끼는 열환경 개선에 대하여 정량적으로 검증하여 설계 및 시공단계에서 활용할 수 있는 기초적 자료를 제공하고자 하였다. 연구결과는 다음 과 같다. 미기후 실측에 의한 측점별 조경공사 전·후의 온도저감을 비교 분석한 결과, 오전 10 시 조경공사 전 평균온도는 34.5℃이며, 조경공사 후 평균온도는 32.5℃로 2.0℃온도저감 효과가 있는 것으로 분석되었으며, 오후 2시 조경공사 전 평균온도는 37.5℃이며, 조경공사 후 평균 온도는 35.9℃로 1.6℃ 온도저감 효과가 있는 것으로 분석되었다. 오후 5시 조경공사 전 평균온 도는 33.8℃이며, 조경공사 후 평균온도는 31.2℃로 2.6℃ 온도저감 효과가 있는 것으로 분석되었다. 연구결과의 활용방안으로 정량적인 연구방법과 결과는 디자이너의 직관적인 조경설계에 객관성을 부여하는 기초자료로서 활용이 가능할 것이다.

Safety accidents, which are called industrial accidents in construction work, are often caused by unstable physical and personal conditions combined during preparation and execution of work. It is difficult to manage all the construction works, but especially in the field of apartment construction work, complex and many kinds of works are being carried out at the same time. In the current construction, safety regulations such as safety management guidelines are generally well maintained, but the execution of manpower resources that can fulfill them is limited, and it is difficult to reduce the accident rate and loss cost. Therefore, in this study, it is a reality that most of the types of construction work are under contruction by subcontracting contract, so they are limit by methods of manual maintenance and safety education. Currently, the subcontractor is also allowed to perform safety management through the composition of the safety management review body, but it is operated formally. So alternatives to this were studied. As a result, safety accidents occur in the subcontractor's workplace due to vertical integration, which is a characteristic of the construction industry. Therefore, the safety management should be carried out by the subcontractor as well as the subcontractor It is concluded that effective and practical safety management can be achieved when management based on the personality that can communicate with each other through the management team is able to reduce the accident rate and loss cost.

In construction work, safety accidents often occur in combination with unstable physical and human conditions during preparation and execution of work. In Korea, the accident rate is higher to that of any country in the world. Therefore, it is necessary to take measures by fundamental prescription. In this paper, in the case of construction safety management, we tried to find a reasonable alternative through a questionnaire survey to apply to subcontracting and small-scale construction. In conclusion, workers who are well aware of the task could be able to reduce the accident rate by deploying them as safety management officers after receiving the training.

Safety accident in Building construction work in the process of preparation and implementation of the insecure human, material status is often caused by combining the reality is that many things. Accident rate is a similar level in the case of Korea and foreign countries than any country in the measures by the higher fundamental prescription is needed. In this paper, construction safety management of subcontracting work and small construction plan to apply through a survey to reach a sensible alternative. I did In conclusion, the educated workers know well, and so on the work schedule then quickly if safety management personnel in disaster will be able to reduce the rate to a miracle appeared.
