The roller machines installed in the industrial field are operated under hazardous conditions due to no safety devices available, human error during operation, defective safety devices, and inadequate regulation even in case that safety devices are provided. Up to now, most roller machines installed in domestic field are provides with band breaking system as a safety device. In this study, the emergency stop distance is measured within the limit of domestic regulation but violates a foreign regulation(EN1417). Consequently, it is concluded that the roller machines with a band breaking system have high possibility of death or serious injury of the operator and the system should be improved with the introduction of additional safety devices. This thesis suggests the safety measures suitable for the roller machines with different drive systems based on the experiment results. The use of the newly developed safety system has been tested on many cases.

Accident rate in the construction industry of South Korea is increasing every year, and it represents the highest percentage among industries. This shows that activities performed to prevent safety accidents in the country are not efficient when it comes to reduce the accident rate. In order to resolve this issue, a model for the prediction of human accidents should be established. In addition, it is required a quantification study based on pattern of human accidents. Therefore, the objective of this study is to quantify uncertainty of human accidents risk and predict how to change in various circumstances by using Monte Carlo Simulation. To achieve the objective, first, pattern of human accidents was defined. Second, insurance claim payout and information of human accidents during 14 years in construction site were collected. Third, descriptive analysis is conducted to determine the characteristics of the accident pattern. Fourth, to quantitatively analyze the pattern of the human accidents, the population of each accident occurrence and payout were estimated. Finally, estimated populations was analyzed according to characteristics of distribution by using Monte carlo simulation. In the future, this study can be used as a reference for developing the safety management checklist in construction site and development of prediction models of human accident.

Although safety and health education is reported to be very effective in reducing the industrial accident rate, the demand for improvement in safety and health education is also very high. The purpose of this study is to present measures to enhance effectiveness by investigating the effectiveness and demand for safety and health education for supervisors among the safety and health education systems. As a result of the study, it was found that the satisfaction and effectiveness of safety and health education were low. As the most important competency required for supervisors, it was investigated that job competency was the ability to discover harmful risk factors and formulate disaster prevention measures in the work process and work environment, and base competency was communication ability. In addition to designated safety and health education institutions, there was a high demand for recognition as education completion time even when professional education by job was completed by other professional education institutions. Therefore, in safety and health education for supervisors, it is necessary to focus on major items to improve supervisors' job competency and base competency, and to recognize that they have completed education at a wide range of educational institutions. We believe that it can increase the supervisor's capacity for safety management and improve the effectiveness of safety and health education.

For workers, industrial accidents exert a bad effect on the productivity, quality of life, and depress the morale. This study aimed to examine the overall influence on job performance of employees who returned to work after industrial accidents. This was a cross-sectional study using the data of 2013 and 2014 Panel Study of Worker's Compensation Insurance (PSWCI), and we performed logistic-regression analysis to analyze an affinity between general characteristics and job performance as independent variable and outcome variable, respectively. As a result, the major factor depressed the job performance were the 1 - 7 degree of disabilities and injuries with convalescence period for 6 to 9month or more than 12 months. In other words, this study shown that job performance was decreased as higher degree of disability and longer convalescence period. Job performance is the factor to identify indirectly worker's successful return to work, and it is important in follow-up of workers who returned to work after industrial accidents. Stable job performance of an industrial disaster victim is the key factor to maintain worker's comfortable and qualitative life as well as increase of productive capacity.

The present study was conducted to investigate the status of industrial injuries through a prospective study for a year from August 1980 to July 1981. The subjects were 15 textile industries which were selected by random sampling in Daegu. The results obtained are as follows: Anual over-all incidence rate of industrial injuries was 3.3 percent and the rate showed 6.7 percent in male and 2 percent in female. The rate showed decreasing tendency with larger scale of industries. By the age group, $15{\sim}19$ age group was the highest as 49.3 percent. Age specific incidence rate of industrial injuries revealed highest as 4.7 precent among the group the group of 30 years old and over. By the years of service, 57.1 percent of the total cases belonged to the the group less than 1 year and the rate revealed increasing tendency with shorter period of service. The highest frequency of industrial injuries was observed at the point of 3 hours after the beginning of the work in a day as 18.1 percent. Frequency of industrial injuries showed highest as 20.3 percent on Monday. Frequency of industrial injuries was highest as 27.7 percent in winter time and showed 14 percent and 11.8 percent in January and August, respectively. By the cause of injuries, machinery accidents showed the highest as 39.2 percent and followed by the accidents due to striking against object as 17.8 percent, fall of ground as 16.3 percent and hand tool as 7.2 percent. Frequency of injured parts of body was highest as 43.9 percent in fingers. The frequency was much higher in upper extremities (66.9%) than in lower extremities (17.6%). By the kind of injuries, laceration wound was highestas 35.7 percent and the next was superficial injury and contusion as 35.1 percent. By the duration of treatment, most of the cases was belonged to the group less than 1 month as 79.1 percent and the duration showed prolonging tendency with larger scale of industries.

현재 우리나라는 1970년대 이후 급속한 경제성장으로 인하여 산업화 및 도시화 현상이 심화되고 있는 실정이며, 이러한 과정에서 불투수층의 증가로 인하여 첨두유출량의 증가, 자연유역에서 도시유역으로 변하면서 유역내 도달시간의 감소 등의 수문학적 특성이 변화로 예기치 못한 홍수로 인하여 피해가 발생하고 있다. 다라서 첨두유출량이 관망으로 전달되는 과정에서 관에 발생하는 부하의 증가로 인하여 내수침수 피해를 입게 되는데, 도시 유역에서의 인구 증가 및 산업활동에 따른 도시 개발로 인한 불투수면적의 증가로 우수유출량이 커지고 있으며, 저지대의 활용이 증대됨에 따라 내수 피해는 더욱 증가되고 있는 실정이다. 이러한 도시 유역의 재배 저감 대책 수립을 위해서는 먼저 실측자료와 도시유출 모형에서 산정된 첨두유출량과의 비교$\cdot$분석하여 최적의 모형을 채택하여야 한다. 또한 채택된 모형으로 적절한 설계 강우량이 선정되어야 하고, 그에 따른 유출량을 정확히 산정하여야 하나, 설계 강우량 산정을 위한 강우의 지속시간의 결정에 대해서 일반적인 기준이 확립되지 못하고 있는 실정이기에 재해 저감 대책 수립에 많은 어려움이 따르고 있다. 이에 본 연구에서는 실측 강우량, 첨두유출량 및 유출총량과 도시지역의 유출량 산정에 사용되어지는 ILLUDAS, SWMM 모형에 모의치와의 비교 연구를 통해 최적의 도시유출모형을 제시하고자 한다. 따라서 실측자료가 있는 서울시 장안$\cdot$뚝섬배수구역의 실측 강우와 펌프장에서 조사된 실측 유량과 ILLUD AS, SWMM 모형에 의해 산정된 유량과의 비교 분석 결과 SWMM 모형에 의한 첨두유량이 실측 첨두유출량과의 오차율에서 장안배수구역은 $21.1\%$, 뚝섬배수구역은 $4.3\%$로 가장 근접한 결과를 나타내었으며, 총 유출량에서도 각각 $7.8\%,\;13.2\%$의 오차율을 가지는 것으로 분석되어 타 모형에 비해 실유량과의 차가 가장 적은 것으로 모의되었다. 향후 도시유출을 모의하는 데 가장 근사한 유출량을 산정할 수 있는 근거가 될 것이며, 도시재해 저감대책을 수립하는데 기여할 수 있을 것이라 판단된다.
