According to the 2020 industrial accident reports of the Ministry of Employment and Labor, the number of fatal accidents in the construction industry over the past 5 years has been higher than in other industries. Of these more than 50% of fatal accidents are initially caused by fall accidents. The central government is intensively managing falling/jamming protection device and the use of personal protective equipment to eradicate the inappropriate factors disrupting safety at construction sites. In addition, although efforts have been made to prevent safety accidents with the proposal of the Special Act on Construction Safety, fatalities on construction sites are constantly occurring. Therefore, this study developed a model that automatically detects the wearing state of the worker's safety helmet and belt using computer vision technology. In considerations of conditions occurring at construction sites, we suggest an optimization method, which has been verified in terms of the accuracy and operation speed of the proposed model. As a result, it is possible to improve the efficiency of inspection and patrol by construction site managers, which is expected to contribute to reinforcing competency of safety management.

According to 'The Analysis of Industrial Accidents in 2016' by Ministry of Employment and Labor, the number of deaths caused by accidents in the construction field is 391, accounting for 47% of 826 industrial fatalities in all industries. The breakdown of the 391 fatalities of the construction industry shows that 'struck by an object' accident had 30 fatalities, the 3rd in frequency following falling (235) and crashing (32) accidents. This study aims to explore ways to reduce the 'struck by an object' accident with emphasis on safety education and certificate system for rigging and slinging works. This study reviews literature on rigging and slinging works and analyzes 'struck by an object' accidents. The rules and regulation on the rigging and slinging works are also reviewed both for Korea and other countries with best practices in construction safety such as Singapore, Japan, U.K., and U.S. The rigging and slinging certificate systems of those countries are also reviewed to find any advantage in the construction safety management. In addition, a pilot rigging and slinging certificate system was executed in one of domestic construction site followed by two surveys: one on the riggers who participated in the pilot operation and the other on general managers in domestic construction sites. Based on the analysis of the 'struck by an object' accidents and pilot operation, this study proposes a rigging and slinging certificate system to reduce accidents, enhancing safety condition of construction sites. The certificate system was proposed in a way to accommodate working practice of construction sites. Depending on rigging careers and a crane load capacity, riggers are eligible to apply either basic or master certificate which makes difference in the level of rigging works. The safety condition of rigging and slinging work could be substantially enhanced if workers, managers, supervisors, administrators, and policy makers work together consistently.

Although the safety management plan review system according to the Construction Technology Promotion Act for securing the safety of the construction work is a fundamental system essential for the prevention of the construction industry disaster, the necessity of its improvement has been raised because it often fails to meet the original purpose. In this study, through the analysis of the effect of the safety management plan and the problems of the operation, we suggest ways to improve it in view of the construction accident reduction and conducted surveys on the construction site through the questionnaires of the client, construction company, and construction business technology manager. In order to improve the effectiveness of this system as a result of the study, it is necessary to distribute the guidelines for the preparation of the safety management plan, manuals, etc., to simplify the contents of the safety management plan, also the step-by-step approval of the safety plan can be a solution. For this, it is necessary to revise the policy through consultation with the Ministry of Land, Transport and Maritime Affairs and related experts.

건설산업에서 폐기물 관리는 환경적${\cdot}$경제적 측면에서 중대한 영향을 미침에도 불구하고, 건설폐기물 관련 통계자료에 의하면 국내 건설폐기물 관리 수준이 상대적으로 낮음을 알 수 있다. 이에 따라 본 연구는 건설폐기물 관리의 요체인 건설폐기물 관리 지침을 고찰하여 문제점을 분석하고, 효과적인 폐기물 관리를 유도하는데 적합한 건설폐기물 관리 지침 개선 방향을 제시하고자 한다. 국내 기존 건설폐기물 관리 지침을 분석한 결과, 폐기물 관리의 목적이 총체적으로 법적인 기준을 벗어나지 않도록 관리하는 데 초점이 맞추어져 있음으로 인해 분석 기준인 "계획, 실행 및 운영, 점검 및 시정조치" 측면에서 효과적인 폐기물 관리 지침으로서의 역할을 다하고 있지 않음을 파악하였다. 또한, 문제점 분석 결과를 기반으로 "계획, 실행 및 운영, 점검 및 시정조치" 측면에서 국내 건설폐기물 관리 지침의 개선 방향을 제시하였다.

Traditional construction planning based on historical data and heuristic adjustment can no longer incorporate all the operational details and guarantee the expected performance. The variation between the expected and the actual production leads to cost overruns or delay. Although predicting reliable productivity on construction site is getting more important, the difficulty of this increases. In this regard, this paper suggested to develop BIM-integrated simulation framework. This framework could predict productivity dynamics by considering factors affecting on construction productivity at operational phase. We developed the following processes; 1) enabling a BIM model to produce input data for simulation; 2) developing the construction operation simulation; 3) running simulation using BIM data and obtaining productivity results. The BIM-integrated simulation framework was tested with structural steel erection model because steel erection work is one of the most critical process influencing on the whole construction budget and duration. We could improve to predict more dynamic productivity from this framework, and this reliable productivity helps construction managers to optimize resource allocation, increase schedule reliability, save storage cost, and reduce material loss.

Many companies have implemented ERP systems to enhance their process competitiveness. Since most ERP systems down to date are implemented and managed on each separated business-unit or company level, such systems run short of the consideration about global business processes and global system managements. In order to integrate a successful global ERP, it is essential to apply the well-systematic implementation methodology which considers global standardization and global IT requirements. It is, however, the actual circumstance that such well-structured methodologies for global ERP implementation are hardly shown not only from domestic site but from foreign one. This paper indicates the global ERP implementation guideline with integrated approach including; the standard process design for efficient execution of global business; the ERP implementation method considering global IT requirements; and, the management method for global system operation. GSI ERP methodology is composed of 3 Phase：Global Strategy Planning, Global Template Construction and Global Roll-Out. Phase1; Global Strategy Planning contains Environment Analysis, GSI direction and Implementation Plan. Phase2; Global Template Construction contains Business blueprint, GSI operation design and Global template implementation. Phase3; Global Roll-out contains local business analysis, local ERP implementation and Global ERP Operation.
