건설기능인력은 최종 생산자로서 생산성 및 품질에 직접적으로 영향을 미치는 중요한 요소임에도 불구하고 방치된 채 고령화되고 고갈되는 양상을 띄고 있다. 이는 궁극적으로 젊은 기능인력의 건설사업 회피에서 기인한 것이다. 따라서 본 연구의 목적은 양질의 기능인력 수급을 위해서 기능인력의 자격 및 직급체계를 제안하여 건설기능인력 시장에 젊은 기능인력을 끌어들이는데 있다. 먼저, 본 연구에서는 국내 건설기능인력 체계의 현황과 문제점을 연구하였다. 그리고 전문가와의 면담과 독일, 호주의 사례 연구를 통해 국내에 적용 가능한 자격 및 직급체계 구축방안을 제안하였다. 본 연구에서 제안하고 있는 건설기능인력의 자격 및 직급체계의 활성화는 기능인력이 단순한 노무라는 이미지에서 탈피하여 전문분야임을 인식시킬 수 있으며, 젊고 유능한 기능인력을 건설산업으로 유입시킴으로써 건설기능인력의 생산성 향상, 전문성 강화, 고령화를 탈피시킬 수 있을 것으로 판단된다. 또한, 사회보장제도와의 연계를 통하여 고용안정화를 도모할 수 있을 것이다.

This study analyzed working postures using the Ovako Working Posture Analysis System (OWAS) to improve work clothes for construction workers. A video taken at a construction work site was stopped at regular intervals and the postures of relevant body parts proposed by OWAS was recorded. Additionally, based on analysis of the working postures code, the level of work action for each postures was classified from stage I to IV. General workers frequently straightened or bent forward at the waist, and used their legs to stand, bend, or walk. Wood workers moved extensively from the waist, keeping their legs relatively straight and their arms held below their shoulders, repeatedly tapping with a hammer weighing less than 10.0kg. Rebar bending workers mainly bent forward at the waist, with both legs bent or standing with one leg bent. Rebar transport and fixing workers walked with the waist straight, and occasionally one or both hands held above the shoulders. Their work also involved holding a hook, which weigh less than 10.0kg, in their hands, and the difficult task of lifting and placing long rebars, which weigh from 10.0 to 20.0kg or more. Concrete pouring workers bent or twisted their back to the side. Therefore, this study suggests that design goals should be different when developing workwear for each type of worker.

A construction site is a highly complex and constantly changing environment, where hazardous areas are difficult to detect if workers lack sufficient knowledge and awareness. Thus, frequent worker safety training is required. Numerous studies on using virtual reality (VR) for safety training were published. While they demonstrate the potential for improving the skills necessary to avoid accidents in the construction industry, they remain difficult to apply at actual construction sites. VR requires specialized hardware and software, limiting workers' access and restricting workers' participation in training sessions. As a result, this paper proposes multiple platforms for immersive virtual reality safety training (VRMP) based on Industry Foundation Classes (IFC) and web technologies such as immersive web (WebXR). The VRMP is compatible with mobile and desktop devices currently by workers and demonstrates scenario models familiar to workers. Also, it reduces development time by utilizing Building Information Models (BIM). Additionally, The VRMP collects data from workers in a virtual environment to assess each worker's safety level, assisting workers in effectively and comfortably gaining a better understanding and raising their awareness. This paper develops a case study based on the VRPM in order to assess its effectiveness.

The number of deaths in the korean construction industry is more than three times the OECD average. Although safety management system should be improved to prevent the safety accidents, it is difficult to improve due to domestic safety conditions. Especially, in order to prevent accidents at construction sites, there is an increasing tendency to monitor the movement of workers and equipment in real time by introducing a location positioning system. Therefore, this study proposes a system that can monitor the position of workers and heavy equipments in real - time, detect danger and transmit alarms so that workers can pay attention to safety and keep safety. The system is expected to reduce safety accidents by transmitting alarms to workers so that they can pay attention.

대한민국 총 인구에서 50세 이상 준고령자가 차지하는 비율은 2010년 29.2%에서 2015년 34.8%로 증가하였다. 이에 따라 전체 건설근로자 대비 50세 이상 건설근로자의 비율은 2010년 20.1%에서 2015년 27.0%로 증가하였다. 이러한 노령화 시대에 맞추어 건설업계에서는 장년근로자들에 대한 재해예방대책을 주어진 사업목표, 예산집행 등을 절차에 맞게 충실히 수행해왔으나 근본적인 재해예방에 한계가 있었다. 이는 건설재해예방의 대책들이 아직까지 장년근로자보다는 전 연령을 고려하고 있기 때문이라 판단된다. 본 연구에서는 건설현장에서의 장년근로자의 안전보건실태를 조사하고 재해감소방안을 제시하였다. 특히 급격히 증가되고 있는 장년근로자의 재해를 감소시키기 위하여 관련문헌 및 안전규정과 산업재해원인통계, 산업재해현황통계 등을 고찰하고, 전국 건설현장에서 공사활동에 직접 참여하고 있는 근로자 3,549명을 대상으로 한 설문조사를 통해 안전보건 실태를 조사, 그간의 재해예방사업 추진현황 및 문제점 분석 등을 통한 재해감소 종합대책을 제시하였다. 본 논문에서 제시한 대책을 실제 정책에 반영할 수 있다면 점진적으로 증가추세인 건설현장에서의 장년근로자 재해를 줄일 수 있을 것으로 기대된다.

Due to hazardous working environments at complex, unstructured, and dynamic construction sites, workers frequently face potential safety and health risks throughout the construction process. In this regard, addressing safety challenges remains one of the top priorities. Construction workers' ability to identify and assess risks is acquired through training, which is one of the primary key factors to determine their safety and wellbeing in hazardous working environments. As such, safety managers constantly focus on the effectiveness of the training materials provided to the workers. However, the construction workers are considerably at greater risk of injuries and fatalities compared to the workers in other industries. In this regard, further studies are required to build up a body of knowledge on the conventional safety training approaches as well as their evaluation techniques in order to boost up the adoption by the practitioners in a widespread manner. This paper provides a systematic review of the current safety training approaches and the various techniques for measuring their effectiveness. The attributes of the current safety training methods for construction workers and their evaluation techniques are identified and analyzed. Results indicated that: 1) immersive environment-based training methods are effective than the traditional safety training methods; 2) this effectiveness can be empirically supported by evaluation strategies, but the current techniques are subjective, intrusive, and error-prone. This research offers fresh opportunities to investigate the training strategies by objectively monitoring the physiological responses of construction crews. The results of this study can be used by researchers and practitioners to identify and determine optimal safety training programs that could potentially become ubiquitous in the construction industry.

This study examined the effect of safety leadership coaching program on managers' safety management and workers' safety behaviors in construction site. Three or four managers and about one hundred workers at each site participated in this study. Safety leadership coaching program consisted of safety leadership education, goal setting, self-monitoring and feedback on workers' safety behavior, reward for three safety management behaviors; (1) safety observations of workers safety behavior and (2) providing positive feedback on safe behavior (3) providing corrective feedback on risk behavior and daily safety education for workers. Dependent variables were the percentage of safe behaviors of workers and frequency of managers' safety management behaviors. A nonconcurrent AB multiple baseline design across settings was adopted. After baseline(A), safety leadership coaching program (B) was introduced to each site. The results showed that safety leadership coaching program was effective to increase managers' and workers' safety behaviors. These results suggest that safety leadership coaching program developed in this study would be an alternative treatment technique to improve construction safety management. In addition, the implications, limitations of this study, and future studies are discussed.
