The duty of construction clients in WSH (Workplace Safety and Health) system was included in the amendment of Occupational Safety and Health Act (enforced on 16 January 2020), which was estimated the shift of paradigm in the prevention of construction accidents. The purpose of this paper is to introduce the analysis results of construction clients' role in the construction project, which were performed by authors over the recent years in order to impose the duty on construction clients, and to suggest their role according the plan, design, and construction stage. Utilizing the systematic literature review process based on Meta analysis, the related papers were selected. For the selected papers, related domestic and foreign regulations, and other prominent report, the construction clients' role was analyzed by reflecting the experts' advice. Results show that the construction clients should control the designer and contractor for implementing the WHS system during the whole process of the construction project. They should supply sufficient source and time to ensure the workers' safety. In the plan stage, the key role of construction clients is to identify intensively controlled hazard and risk reduction plan and to transfer the results. In the design stage, their key role is to select the designer with the capacity in WSH and to assist the designer for the safety design. The main key role of construction clients in the costruction stage is to select the contractor with specialty in WSH including a contract reflecting the WSH requirement and to check implementation of WSH plan, WSH cost, WSH education, and accident report. In addition, it is thought that the construction clients' participations in the site WSH activity and adjustment of safety and health problem among contractors can be effect in the prevention of construction accidents.

To stem the ever-prevalent occurrence of industrial accidents in the construction industry, which is emerging as a social problem, efforts must be invested by various stakeholders. Specifically, among stakeholders, the orderer is at the top of a project's decision-making structure. Therefore, the orderer's awareness of safety and health directly affects the process of securing the safety of the overall construction site. In this light, the present study aims to identify differences in the perceptions of each stakeholder regarding the obligatory safety and health measures for clients that have recently been introduced. In addition, it suggests specific implementation plans in the Korean context. The data used for analysis were collected through a survey targeting stakeholders such as orderers, safety managers, and site managers, and the collected data were quantitatively reviewed by using multivariate analysis methods such as analysis of variance. As a result of the analysis, the introduction of safety and health obligations for the owner was found to be necessary, and the designation and operation of safety and health experts as an action plan was deemed reasonable. The authors expect that the results of this study can be used as basic data for revising the related regulations in Korea. Moreover, as a further study, a review of the effectiveness after improving regulations would contribute strongly to the domain. -

건설공사 발주자에게 건설현장 근로자에 대한 안전보건관리 책무를 부여하는 안전보건대장 제도가 「산업안전보건법」 전부개정에 포함되어 도입되었다. 안전보건대장 제도에 대한 낮은 인식과 이행률로 발생되는 제도의 실효성 문제를 해결하기 위해서는 경제성 측면에서 제도의 효과성을 설명할 필요가 있으므로 본 연구에서는 안전보건대장 도입 당시 논의되었던 자료를 근거로 비용편익분석을 활용하여 안전보건제도 이행의 경제적 효과를 분석하였다. 안전보건대장 제도 이행에 있어 추가적인 비용이 발생하는 것은 설계안전보건대장의 작성 및 관리로 분석되었다. 작성비용과 산업재해 감소로 발생되는 직ㆍ간접적 편익을 비교한 결과 편익이 비용보다 높게 평가되었으므로 안전보건대장 제도는 건설공사 재해 감소와 경제적 효과를 발생시키는 것으로 판단된다. The safety and health ledger system, which gives the responsibility of safety and health management for construction site workers to the construction project owner, was introduced as part of the overall revision of the Occupational Safety and Health Act. There is a need to explain the system’s effectiveness in terms of economic feasibility to solve the execution problem of the system caused by low awareness and implementation rate. In this study, the economic effect of implementing the safety and health ledger system was analyzed using cost-benefit analysis based on the data discussed at the time of the introduction of the system. Results show that creating and managing the design safety and health ledger caused additional costs in implementing the system. As a result of comparing the cost of preparation and the direct and indirect benefits caused by the reduction of industrial accidents, the benefits were evaluated higher than the costs. Thus, it is thought that the safety and health ledger system reduces construction work accidents and generates economic effects.

중ㆍ소규모 건설현장 재해예방 기술지도 대가 개선에 관한 연구

공사금액 1억이상 120억 미만 중ㆍ소규모 건설현장은 전문지도기관의 기술지도를 받아야 한다. 최근 기술지도의 계약 주체가 시공자에서 발주자로 변경됨에 따라 예상되는 기술지도 부실을 방지하기 위해 기술지도 대가를 산정하는 방법을 제안 하였다. 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. Under Korean law, small-to-medium-sized construction projects with budgets of more than 100 million won and less than 12 billion won must receive technical guidance by a visiting technician belonging to a specialized institution. This study proposed a method for calculating the technical guidance fee to prevent the potential inadequacy of technical guidance when the responsibility providing the technical guidance fee is changed from a contractor to a client. The method simplified the construction works which should receive technical guidance into four sections according to the construction amount. For each section, the number of instances of technical guidance per day provided by the visiting technician and the minimum technical grade of the visiting technician were limited, and the guideline for estimating engineering services fees was applied to calculate the fee per instance of technical guidance. The results show that the proposed method can be applied to the establishment of a technical guidance fee guideline since it well reflects the current fee distribution and K2B analysis results.

수열결정화법에 의한 A 형 제올라이트 박막의 제조

임철수,박노춘,남세종,김건종 한국공업화학회 1998 한국공업화학회 연구논문 초록집 Vol.1994 No.1

A type zeolitic crystal film was synthesized on porous supports from the reaction mixture of 1.9 SiO₂-1.5 Na₂O-Al₂O₃-40 H₂O. The zeolite film was characterized by XRD and SEM. The crystals grown on the porous matrix were very closely bound together and the thickness of membrane was about 8 - l5㎛. The densely intergrown crystals could be also synthesized by e hydrothermal treatment at 100℃ after pressing the reaction mixture without addition of water, A zeolite membrane crystallized as a thin film showed the selective permeability of water from water and methanol mixture through the molecular sieving activity of micropores.
