In this study, the purpose of the study was to verify the relationship between the company's construction safety management system and workers' safety consciousness and safety observance behavior. A survey of 357 workers was conducted and a statistical analysis was performed using the SPSS 25.0 program. As a result, the following main results were obtained: First, it was found that supervisor's capability, inner construction safety management, construction safety education, and construction disaster evaluation have significant effects on the worker's safety consciousness. Second, it was revealed that the worker's safety consciousness had a significant positive effect on the safety observance behavior. Third, it was shown that supervisor's capability, inner construction safety management, construction safety education, and construction disaster evaluation have significant effects on safety observance behavior. In addition, this study confirmed that the management supervisor's ability to handle safety at the work site is the most important factor in safety management in order to enhance the worker's safety consciousness and safety observance behavior.

The regulatory recognition, regulatory approval, and observance for employer, inspector, and worker groups were investigated for the Korean measurement system in working environments. The employer, worker, and inspector showed an agreement of 90~97 % for the measurement of working environments. This survey showed that the measurement system of working environments has been settled in Korea. However, this survey showed an agreement of 81~87 % for reporting the results of working environment, involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement. The employer recognized well for the measurement of working environments, involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement, but the employee did not recognize well them as much as the employer did. Thus, the improvements for the recognition for involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement by the employee are needed.

The aim of this study is that HPMA(Hazard Potentials in My Areas) System is to present for establishment of the voluntary safety management on industrial region. HPMA System Itself means that manager, supuryisor and worker on process-line find out the hazardous and/or unsafe potentials from their work places and make the plan of improvement by means of mutual communication with top manager and the department of safety staff, eventually put in the practice. In case that it takes the longer time to improve hazard potentials and is impossible improvement by existing technique, appropriate check-list will be used by the worker himself on the identified production line. Form this system, therefore, it makes them to get more and more sensitivity to the hazards. In this study, we present the voluntary safety management system which is controlable systematically and in the final analysis the direction of safety management by computerization of HPMA System which is activated in their work places.

This study has performed to identify the effect of safety behavior, safety climate and its satisfaction through the Behavior Based Safety Program for 5 sites of the same Company. The study result indicated that the level of recognized safety behavior, climate and its satisfaction improved by conducting observation of worker behavior, jobsite feedback, displaying feedback chart, safety training, behavior modification committee. Additionally, the participation level of safety activity and conformity level of safety rule improved. The recognized level of safety climate improved together with recognized safety value by management, safety participation of direct boss, communication with each other to be dealt with safety matter, safety training material to be contained unsafe behavior and practical hazard, understanding and conducting safety standard. In addition, The recognized level of satisfaction improved together with safety behavior and climate. As a result, this program provided an opportunities to correct worker's unsafe behavior to safe behavior in conjunction with increasing number of observation, providing additional time to have a safety check, safety suggestion to improve work situation and a permit to work rule. It will be integrated into health and safety management system to be able to reduce industrial accident.

Objectives: The aim of the study was to investigate the knowledge and attitude toward radiation safety management in dental clinic worker. Methods: A self-reported questionnaire was filled out by 294 dental clinic workers in dental hospitals and clinics in Gwangju and Jeonnam from February 17 to March 30, 2014. The questionnaire consisted of general characteristics of radiation safety(8 questions), knowledge of radiation safety(15 questions), and attitudes of radiation safety(16 questions). The survey was done by Likert 5 scale method. Results: In completion of the radiodontia courses, 84.0% of the learners were female workers. 88.0% of the learners took the theoretical and practical courses. Those who work in the university dental hospital accounted for 87.1% and those in dental clinics accounted for 83.2%. Majority of the workers took on Leaden protective clothing in order to protect the thyroid gland. Male workers had more knowledge toward the radiation safety management than the female workers. The attitude toward the radiation safety management revealed the significant differences between age, gender, academic careers, license, clinical careers and the mean number of patients per day(p<0.05). Conclusions: The radiation safety management is very important in dental clinical workers and it is necessary to enhance the attitude toward the radiation safety through continuous education.

When picking up cargo, workers manually load and unload the cargo. Workers have different intensity of work depending on the amount and weight of cargo. In particular, as the intensity of manual work increases, workers are exposed to cumulative traumatic diseases. A manual for picking safety work for workers cargo handling in the distribution center is required. In this study, the worker's picking safety work based on the cargo volume and weight was presented as an experimental design model. Like the research results, the disease begins when the worker feels the number of pains presented by the model.

Objectives: The purpose of this study is to calculate the worker-DNEL (Derived No Effect Level) values using the REACH guidance and compare the calculated DNELs with existing Korea occupational exposure limits (KOELs) for evaluation of the applicability of the worker-DNELs as provisional occupational exposure limits for chemicals that are not established KOELs in the workplace. Methods: The worker-DNELs for 46 chemicals among 113 hazardous substance requiring management were calculated using the REACH guidance, and a paired t-test was performed to see if there is any statistical difference between two lists (worker-DNELs vs KOELs). The ratios of KOELs over worker-DNELs were also calculated to compare the overall levels of two lists using the geometric means method. Results: The calculated worker-DNELs for 46 chemicals ranged from 0.001 to $329mg/m^3$ (GM= 6.9, GSD = 10.8), and appeared to be a significant difference between the worker-DNELs and the KOELs (p < 0.01). In addition, the ratios of KOELs over worker-DNELs ranged from 0.3 to 394 times (GM = 10.2, GSD = 3.9), indicating that the worker-DNELs were, on average, 27 times lower than the KOELs. Conclusions: Therefore, the study results show that the calculated worker-DNELs can be applied and used as provisional occupational exposure limits in the workplace in order to reduce worker exposures to chemicals and health risks, and manage potential worker exposures based on the precautionary principle through comprehensive chemical risk assessment.
