The objective of this study is to compare on the occupational injury rate and mortality rate of all workers and foreign workers. By doing so, this study seeks to find out the improvements necessary to secure the basic safety net for foreign workers, as well as to find out the legal and institutional measures in place to make timely political intervention and protect the health of foreign workers. The status of foreign workers in Korea, their employment trends by industries, and occupational accident types and scales of Korean and foreign workers were analyzed from 2005 to 2009. Each year, foreign workers' occupational injury rate was much lower than Korea's overall occupational injury rate. But when analyzed by industry, occupational injury rate (death rate per 10,000 workers) of manufacturing industry was about 2 to 5 times higher than the overall occupational injury rate in Korea. Also, construction industry showed 3 to 16 times higher rate than the rate of overall industries. Although the death rate per 10,000 workers showed a declining yearly trend, foreign workers' occupational injury rate has the tendency to increase gradually. In particular, occupational injury rates and death rates per 10,000 workers were considerably high in the manufacturing and construction industries.

The nuclear power plant construction project is a large-scale project that involved a daily maximum of thousands of workers. many equipment and laborers involved has been required consistently to minimize the need for safety through real-time safety management. But current nuclear power plant construction site is only managed to access of workers and equipments. The purpose of this study is the owner requirements reflects the characteristics of the nuclear power plant construction project integrated safety management system utilizing active RFID and GPS positioning technology.

Unsafe actions and behaviors of workers cause most accidents at construction sites. Nowadays, occupational safety is a top priority at construction sites. However, this problem often requires money and effort from investors or construction owners. Therefore, decreasing the accidents rates of workers and saving monitoring costs for contractors is necessary at construction sites. This study proposes an unsafe behavior detection method based on a skeleton model to classify three common unsafe behaviors on the scaffold: climbing, jumping, and running. First, the OpenPose method is used to obtain the workers' key points. Second, all skeleton datasets are aggregated from the temporary size. Third, the key point dataset becomes the input of the action classification model. The method is effective, with an accuracy rate of 89.6% precision and 90.5% recall of unsafe actions correctly detected in the experiment.

건설재해의 직접적인 원인은 작업자의 불안전한 행동과 작업장의 불안전한 상태로 분류할 수 있다. 그러나 작업자의 불안전한 행동의 원인은 불안전한 상태에 비해 상대적으로 발견이 어렵다. 왜냐하면 불안전한 행동은 개인의 인지과정을 거쳐 순식간에 발생하기 때문이다. 따라서 작업자 인지과정모델을 통해 불안전한 행동의 원인을 밝히고 그 관리방안을 밝히는 것이 본 연구의 목적이다. 작업자의 인지과정모델을 개발하기 위해 피드백 관계를 규명하기에 알맞은 시스템 다이내믹스 방법론을 사용하였다. 개발된 인지과정모델은 작업자가 위험을 인식하지 못하는 그 상황 자체의 위험성에 대하여 강조하였으며 작업자가 위험을 인식 하였더라도 불안전한 행동을 할 수 있음을 나타냈다. 또한 불안전한 행동이 바로 사고로 이어지지 않는다는 습관은 작업자의 안전에 대한 부정적 태도인 태도로 이어진다는 점에 대해서도 규명하였다. 이러한 분석은 건설현장의 안전관리자가 작업자의 인지상태를 관리하는데 도움이 될 것이다.

Background: Hong Kong's construction industry currently faces a manpower crisis. Blue-collar workers are a disadvantaged group and suffer higher levels of chronic diseases, for example, cancer, than the wider population. Cancer risk factors are likely to cluster together. We documented prevalence of cancer-associated lifestyle risk behaviors and their correlates among Hong Kong construction workers. Methods: Data were collected from workers at 37 railway-related construction worksites throughout Hong Kong during May 2014. Tobacco use, alcohol consumption, unbalanced nutrition intake, and physical inactivity were included in the analysis. Latent class analysis and multivariable logistic regression were performed to identify the patterns of risk behaviors related to cancer, as well as their impact factors among construction workers in Hong Kong. Results: Overall, 1,443 workers participated. Latent class analysis identified four different behavioral classes in the sample. Fully adjusted multiple logistic regression identified age, gender, years of Hong Kong residency, ethnicity, educational level, and living status differentiated behavioral classes. Conclusion: High levels of lifestyle-related cancer-risk behaviors were found in most of the Hong Kong construction workers studied. The present study contributes to understanding how cancer-related lifestyle risk behaviors cluster among construction workers and relative impact factors of risk behaviors. It is essential to tailor health behavior interventions focused on multiple risk behaviors among different groups for further enlarging the effects on cancer prevention.

Frequent accidents occur when workers at construction sites leave the safety zone, and particularly in the past 5 years, 9 fatal accidents occurred at the Korea Railroad Corporation due to train accidents on other tracks during track work. With the Severe Accident Punishment Act taking effect in January 2022, it is a priority to secure a safe work environment for workers at industrial (construction) sites. Therefore, there is a need to manage workers' departure from the safety zone (construction zone) and to facilitate communication within the construction zone. In this study, a mobile edge computing CCTV system is proposed that uses geofencing to determine whether workers are working in the danger zone, which can judge and respond in real-time to the ever-changing field environment. The proposed system is mobile and flexible, rather than server-based fixed CCTV. However, since it is designed mainly based on images, it has limitations in recognition rate depending on the environment such as distance, viewing angle, and illumination. As a way to compensate for this, it is required to develop more reliable equipment by combining technologies such as LiDAR and Radar.

In current domestic construction field, several factors influencing the safety for field workers are various due to the size and complexity of construction works involved. Among the factors, the age is the important one, because the average age of workers is getting older due to the 3D phenomena in construction fields. The safety for workers of all ages is important, but especially safety for the old, is more important. Thus, the fundamental techniques for placement of field workers with adequate safety corresponding to complexity and hard works are investigated through analyzing fatigue and heart rate of individual worker, especially for the old.

Purpose: The purpose of this study was to identify the relationship between occupational stress and depression of construction workers. Methods: The subjects were 168 construction workers selected from I city and K city in Korea by convenient sampling. The data were collected by self-report questionnaires from August 1 to 31, 2011. The data were analyzed by frequencies, t-test, ANOVA, Tukey test, Pearson correlation coefficient, stepwise multiple linear regression with the SPSS/WIN 15.0 program. Results: The total mean scores of occupational stress on the subjects were 46.65 and lower (below 50%) than those of the Korean male workers, standard. According to the CES-D cut-off point, the prevalence of depression was 25%. The study showed that occupational stress is positively correlated with depression. Conclusion: This study concludes that it is necessary to develop stress management program to reduce occupational stress and depression.

건설종사자가 일으킨 휴먼에러가 건설 사고재해의 중요한 원인 중 하나이므로 사고재해를 줄이기 위해서 건설근로자의 휴먼에러를 줄이는 것이 중요하다. 그러나, 건설업의 특성상 건설근로자는 현장이라는 공통의 틀 안에서 작업을 하고 있으므로, 본 연구는 조직적 관점에서 건설 현장 조직의 안전의식 수준이 건설근로자 휴먼에러에 미치는 영향을 파악하였다. 분석 결과 휴먼에러가 사고재해에 영향을 미치며, 건설 현장의 안전의식 수준이 건설근로자의 휴먼에러에 영향을 미친다는 것을 알 수 있었다. 특히, 잘못은 안전의식의 거의 모든 영역에서 현장의 안전의식 수준과 상관관계가 있는 것으로 나타났다. 본 연구는 건설 현장의 안전의식 수준을 높이면 건설근로자가 잘못된 행동(행위착오, Slip)을 할 가능성이 작아져 궁극적으로 건설 현장의 사고재해를 줄일 수 있다는 것을 파악한 점에서 의의가 있다고 할 수 있다.

안전교육은 작업장 위험에 대해 자기 스스로 보호할 수 있는 기본적인 방법이라고 안전교육 전문가들이 언급한 것처럼 안전교육은 재해예방에 별다른 제한 없이 효율적으로 사용될 수 있는 중요한 안전대책이다. 그러나 건설현장에서의 안전교육은 매우 형식에 치우쳐 교육을 위한 교육일 뿐이며 근로자들에게 안전교육 시간은 지루하고 따분한 시간일 뿐이다. 이러한 이유는 자기와 상관없는 교육내용과 개인적 특성을 무시한 일괄교육에서 기인하며 이는 더 이상 근로자의 자발적 참여를 유도하지 못한다. 따라서 건설근로자들의 개인적 특성에 맞는 다양한 안전교육모델 개발이 필요하다. 이에 본 연구는 건설근로자의 개인적 특성에 맞는 안전교육 모델을 구축하는데 필요한 기초자료를 제공하기 위해 선행연구 분석 및 면담조사를 통해 건설근로자들의 대표적인 개인적 특성 요소와 안전교육 요소를 도출하여 각각의 분류체계를 구축하였으며 마지막으로 건설현장의 근로자에 대한 사례적용을 통해 건설 안전교육의 개선방향을 제시하였다.
