The number of construction accident deaths in Korea is increasing and most causes of construction accidents are human factors. Voluntary participation of construction workers in safety activities is likely to improve these human factors and increase the prevention effect of construction accidents. Therefore, there is a need to study the motivation of workers to meet the voluntary participation of construction workers. In this respect, the purpose of this study is to compare the importance of construction field engineers and construction managers about the safety motivation factors of construction workers. This study analyzed the results of the questionnaire survey about safety motivation factors and conducted a T-test for these factors. The results of this study can be used as managing method to effective on-site safety management by minimizing the difference between the two groups according to motivation factors of construction workers.

This research focuses on comparing the impact that working conditions have on the job satisfaction of Korean and Chinese-Korean construction workers. The data shows that factors such as the quality of wages, food catering, and leisure facilities showed a positive correlation on the workers' satisfaction. Further comparative analysis showed differences between the effect these factors have on the satisfaction of Korean workers and Chinese-Korean workers, who occupy the highest portion of the foreign workforce in Korea. The analysis concluded that to the Chinese-Korean workers, wage had the strongest impact on their satisfaction over other factors, whereas this difference was not present in the Korean workers. The results of this study highlighting these differences between the worker groups can contribute to developing the efficiency of the management of construction sites in Korea.

Metro subway construction is a field that requires a great deal of professional manpower. The aging of professionals has a negative impact on both productivity and health, owing to poor working environments, heavy lifting, underground work, and other factors. To address this issue, the government is progressively revising and enforcing health management law and regulation in the construction industry. Thus, the job stress and work ability of many professional subway construction workers, who are rapidly aging, are being analyzed to ensure their safety and improve their health. In this study, the Macpa stress index of Busan Metro Subway construction workers from Sasang to Hadan line was measured by using a Macpa measurement machine, and a work ability survey was conducted by using the questionnaire that was developed by the FIOH. The independent variables were age, years of service, job position, employment type, and occupation. While, the dependent variables were the Macpa stress index and work ability. The Kruskal-Wallis test was used because it was difficult to assume that the statistics of this study represented a normal distribution. The results showed that age, job position, and employment type affected Macpa stress index and revealed that as the age of the workers increased, their stress levels increased as well. Additionally, job position and employment type affected the work ability of the metro subway construction workers. In terms of job position, the technical engineers were under a lot of stress, and whereas the managers had the best work ability. The technical engineers were more stressed than the other workers because of a poor working environment. In terms of employment type, daily workers were under more stress and lower work ability than others.

Safety education, which aims to cultivate an understanding of safety, to help acquire safety skills, and to improve attitude toward safety, is an important safety measure that doesn't entail restrictions to be carried out efficiently. Furthermore, safety education is perceived to be the most preferred measure in reducing the occurrence of accident. The current practice of safety education In construction sites, however, is all formal and has no substance. Safety education became a mere boring time to workers since the material is not related to them, and does not reflect the individual personalities, which cannot induce voluntary participation of workers. Thus, it is vital to develop various safety education models suitable for individual personalities of construction workers. This study aims to provide the basic data necessary to establish safety education models according to individual personalities of construction workers. On this, the study seeks to present a model for safety education complying with individual personality of construction workers by a survey using questionnaires and statistical analyses to workers on the construction sites.

Recently, there are lacks of construction workers, and such vacancy has been continuously increased in many construction sites. Foreign workers have been hired to fill such vacancy, but increasingly high demands for construction workers made construction companies to hire foreign workers who did not properly pass the health and safety education program. In this work, problems associated with the basic education program for occupational safety and health training, which is the first mandatory requirement for foreign workers, were evaluated to suggest applicable solutions for this program. Literature reviews and preliminary investigations were performed, and a questionnaire survey was conducted for practitioners who were in charge of safety management in various construction sites. Results from survey were analyzed to derive proper methods for improvement on basic education on occupational safety and health training program. It is believed that suggested solution from this work can make foreign workers to be more conscious about health and safety issues, so that it will eventually decrease the accident rate in construction sites.

General workers who assist various technicians in different fields with their work across the whole construction sites without having a particular skill are at risk of the highest accident rate and their accident form becomes varied. Accordingly, this study was conducted to identify the relationship between form of safety accident and influence factor in general workers and analyze accident severity by influence factor. The followings are the results from this study. First, as a result of analyzing major form of accident and influence factors in general workers with network analysis methodology, nine forms of accident and seventeen influence factors were drawn. Second, it was found that in accident severity among general workers, collapsing, among various forms of accident, appeared the highest, followed by fall, electric shock, fire, hit by an object, bumped against, trip, scission getting cut chopped in order. Third, main points of special, concentrated, and permanent management were presented in order to reduce the safety accident in general workers effectively.

Background: The physical work demands of construction work can be reduced using ergonomic measures. The aim of this study was to evaluate the use of ergonomic measures related to musculoskeletal disorders (MSDs) among construction workers. Methods: A questionnaire was sent at baseline and 2 years later to 1,130 construction workers. We established (1) the proportion of workers reporting an increase in their use of ergonomic measures, (2) the proportion of workers reporting a decrease in MSDs, (3) the relative risk for an increase in the use of ergonomic measures and a decrease in MSDs, and (4) workers' knowledge and opinions about the use of ergonomic measures. Results: At follow-up, response rate was 63% (713/1,130). The proportion of workers using ergonomic measures for vertical transport increased (34%, 144/419, p < 0.01); for measures regarding horizontal transport and the positioning of materials, no change was reported. The proportion of workers reporting shoulder complaints decreased (28%, 176/638, p = 0.02). A relationship between the use of ergonomic measures and MSDs was not found; 83% (581/704) of the workers indicated having sufficient knowledge about ergonomic measures. Lightening the physical load was reported to be the main reason for using them. Conclusion: Only the use of ergonomic measures for vertical transport increased over a 2-year period. No relationship between the use of ergonomic measures and MSDs was found. Strategies aimed at improving the availability of ergonomic equipment complemented with individualized advice and training in using them might be the required next steps to increase the use of ergonomic measures.

The South Korean construction industry has shown a high proportion of industrial accidents (approximately 28% of whole injuries) and the continuously increasing accident rate. Although many safety research emphasized that the 3E (Enforcement, Education, and Engineering) approach is a potential solution to enhance workplace safety, there should be benefits to consider psychological (i.e., Emotional) effects on the safety performance since most construction works are human-oriented. Thus, understanding construction workers' psychological conditions can be a priority. This research studied the relationships between psychological conditions-which cover stress, personal temperament, emotional disturbance, and drinking habit-and specific safety-related factors including safety motivation and knowledge, and safety performance of individual workers at a construction site. This study conducted a survey of 430 respondents and analyzed the data with the multiple linear regressions. The results imply persistence, trait anxiety, and problem-focused coping style are the critical factors that should be controlled for enhancing jobsite safety. Finally, the research outcomes could be applied to build a strategic safety management plan for a construction manager.

Knowledge has been one of the key factors influencing the companies' competitive power. Domestic construction industries have introduced Knowledge Management from 1990s around major construction companies. However, construction organizations have recently give a skeptical response about Knowledge Management. The existing Knowledge Management in construction industries does not satisfy the demands of workers. Furthermore it makes workers do double business. Therefore, this study investigates the workers' satisfaction of Knowledge Management, and becomes the preliminary study to suggest how to improve Construction Knowledge Management.
