건설안전 강화를 위한 노력에도 불구하고 국내 건설현장의 안전사고는 계속 증가하고 있다. 시인성 높은 색채를 사용한 안전표지는 근로자가 다른 주의집중 상태로 인해 위험을 인지하지 못할 때, 즉각적으로 장기기억에 내재된 정보를 불러일으킴으로써 건설사고 예방에 기여할 수 있다. 이러한 건설안전표지가 건설현장에서 효과적이고 국제적인 의사소통수단으로 기능하기 위해서는 안전표지색채에 대한 명확하고 통일된 기준과 더불어 건설현장이 갖는 특성을 적절히 반영하는 것이 필요하다. 본 연구는 한국, 미국, 영국 및 호주의 4개국의 건설안전표지 색채기준을 분석하고, 건설산업의 특성을 고려한 안전표지 색채기준 개선방안을 제안하였다. 4개국 모두 파란색을 안전색상으로 지정하고 있는데, 오늘날 건설산업에 많은 고령 근로자가 종사하는 것을 고려한다면, 고령 근로자에게 있어 구분이 어려운 푸른색 계열의 안전표지사용은 부적절하다. 또한, 건설현장은 장소에 따라 밝기가 상이할 뿐만 아니라 야간이나 지하 작업의 경우 충분한 밝기 확보가 어려우므로, 시공간의 변화에 따른 빛 조건을 보정하기 위한 허용오차나 색상 팔레트가 필요하다.

The Central African Region is known as one of the most troubled and unsafe regions in Africa. But more recently the Central African Region has been growing and developing, with many projects underway involving huge local and foreign construction companies. Despite this fact, workers in the Central African Region often encounter unsafe working conditions and must confront many kinds of hazards. Therefore, the aim of this study is to identify the safety management situation in Central African construction sites, by focusing on the countries of Rwanda and DR Congo. Through our research, it was found that the two countries studied in the Central African Region are very similar with regard to their safety management systems, with some exceptions. In addition, it was revealed that both these countries in the Central African Region had good safety performance. This study will help to illuminate the situation of safety systems on construction sites in the Central African Region, and can be used by companies advancing into the Central African Region's construction market.

Construction site fatalities accounted for 51.9% of the total fatalities recorded in 2020. It is known that the safety leadership of site managers is important in reducing occupational accidents at construction sites. According to previous domestic and foreign studies, the safety leadership role of managers has significant effects on the safety behavior and safety culture of workers. Therefore, in this study, we identified the factors affecting organizational trust, which are known to be prerequisites for building a safety culture, and sought ways to enhance organizational trust. In this study, measurement data were collected using a self-report questionnaire. A total of 4,373 copies were distributed to workers and managers of business partners who are highly likely to be exposed to occupational injuries, and 3,873 copies were used as final data for analysis, excluding insincere responses and non-responses. As a result of the study, safety leadership was found to have a positive (+) effect on organizational trust, and communication and motivation moderated the relationship between safety leadership and organizational trust. Therefore, for safety leadership to have a positive effect on organizational trust at construction sites, it is imperative that leadership participation includes communication and motivational efforts.

In this thesis, the domestic and foreign legislative background and legislative process of the Serious Accident Punishment Act were reviewed, and the Serious Accident Punishment Act in Korea was reviewed. In 2022, more safety accidents occurred in the construction industry than in other fields, and in particular, the most deaths occurred in the 'fall' type. In April 2023, regarding two criminal first-instance trial cases, the courts all sentenced guilty, and in one case, the representative of the company(CEO) was sentenced to imprisonment and was arrested. In response, the management side expresses the opinion that the punishment is excessive and there is a concern that corporate management will shrink, while the workers side(Union) argues that the responsibility of the business operator or manager should be strengthened by heavier punishment. As a countermeasure to overcome rationally, we present a plan in terms of legislation and resolution process. In other words, we present a review of the amendment to the Serious Accident Punishment Act and the Court Organization Act. In addition, guidelines for the a safety and health system must be implemented, and if an accident occurs, it must be dealt with reasonably. As a result, safety accidents in the construction industry should drastically decrease and safety culture should be properly established.

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.

In the construction sector, there were 99 fatalities from falls associated with steel tube and system scaffolds for three years from 2016 to 2018 and out of which 27.3 percent (27 workers) were found to have occurred during installing and dismantling procedure. To erect scaffolding which is installed for the work at height, the work platforms are generally installed first and the safety guardrails are installed and vice versa to dismantle. As a result, workers are exposed to the risk of falling because they erect and dismantle scaffolding without guardrails. To minimize the risk of falling, it is necessary to study a new construction method that can erect or dismantle scaffolding while guardrails are installed (called advanced guardrail system). This study analyzed advanced guardrail system in terms of safety regulation, workability and economic efficiency by investigating the domestic situation on the use of scaffolding, reviewing domestic and foreign standards for guardrails and conducting economic feasibility study. The results of this study is expected to greatly contribute to preventing falls in scaffolding installation and dismantlement procedure. As a follow-up study, empirical research is required including physical test of scaffolding with advanced guardrail system and effectiveness analysis after trial applications.

With the recent trend of intelligence and automation of construction work, a double-blade road cutter is being developed that automatically enables cutting along the cutting line marked on the road using a vision system. The road cutter can recognize the cutting line through the camera and correct the driving route in real-time, and it detects the load of the cutting blade in real-time to control the driving speed in case of overload to protect workers and cutting blades. In this study, a vision system mounted on a double-blade road cutter was developed. A cutting route recognition technology was developed to stably recognize cutting lines displayed on non-uniform road surfaces, and performance was verified in similar environments. In addition, a vision sensor protection module was developed to prevent foreign substances (dust, water, etc.) generated during cutting from being attached to the camera.
