Safety engineers should be reasonably assigned to construction sites in order to prevent accidents specially for large-scaled projects. More engineering-oriented safety engineers should be assigned to those large-scaled projects because accident causes are found to be due to more technical aspects rather than general safety problems. more experienced engineers should be assigned to larger scaled projects for covering more technical aspects. This one is analyzed by the existing accident results. This study is to find out some formulae to calculate how many safety engineers should be assigned to construction sites, by amounts, by project kinds, by project scales, by engineer grades. So that construction contractor can assign them to their site economically.

As shown in the accident analysis from 2007, it has been found that causes of accidents on large-scale projects are different from those found in general construction projects. A 300-question survey regarding systematic and practical aspects of safety problems at construction sites was distributed to ten (10) different companies. Participants were to respond subjectively, so that the results could be used to assemble the first formal questionnaire survey. They were collected and compiled by an advisory committee for this study. The resulting surveys were then sent to the division chiefs of the top 100 construction companies in Korea, in order to improve the response rate. The Department of Safety & Health Direction, and the :Ministry of Labor, ROK sent the same sheets to medium and small construction companies that placed within 101-200th of all Korea construction companies. The above safety engineers were classified into four (4) levels, from 1st to 4th, followed by the project dollar amount and risk level. Formulae were developed to assign safety engineers to construction sites by engineer level, the project dollar amount, and the project risk level. Conclusions are summarized as follows: 1) Reviewing the assignment system of experienced safety engineers to large scaled projects - The more experienced the engineers assigned to a project, the higher the level of accident prevention. 2) Enforcing the assignment of advanced level safety engineers to large-scaled sites - At least one advanced-level safety engineer should be assigned to construction sites with projects valued at $15million USD (15,000,000,000). 3) For assigning safety engineers by risk level - Twenty models have been developed to calculate the number of safety engineers to be assigned by risk level. In the future, risk level for each job should be established by the government (as is now the practice in Germany).

Safety education should not only prevent workers from industrial accidents but also contribute to improve the productivity of manufacturing plants or construction sites. In practice this do not happen because workers do not realize the importance of safety education. This study aims to suggest a methodology to improve safety education of construction sites by surveying conditions of safety education and the safety consciousness of workers and engineers. The results showed that most education except regular educations were nominally carried out. Lectures and audio-visual education were mainly used as educational methods. After trainees attended the education session they completed a written survey, the most dissatisfied factor about safety education was education circumstances, of which rate was around 36%. The proportion of construction engineers who thought that safety management was contributable to cost reduction was 35%, to construction period 20%, and to quality enhancement 48%. Based on these results, this research pointed out the need to review training manuals, the development of educational programs, improvement of educational facilities to improve safety education of construction sites, and finally to discussed these issues.

This paper presents a quantitative analysis method to quantitatively indicate a electrical fire preventive effect of safety inspection for electrical facilities for general use. Logic model was developed based on whether enforcement of safety inspection for electrical facilities, and then the developed analysis model was converted to hydraulic model by using mathematical logic. The electrical fire preventive effect of safety inspection for electrical facilities was quantitatively calculated by applying electrical safety inspection results and fire statistics for five years to the developed hydraulic model. The results show that electrical fire preventive effects of 5,542 cases on annual average for five years.

건설산업의 안전사고 중 사망사고는 최근에 증가추세에 있다. 이와 같은 현상은 현재의 관리방법과 법적조치는 한계를 보이고 있다고 할 수 있다. 따라서 본 연구에서는 근로자의 태도와 행동적인 요인을 알아보기 위하여 근로자들이 안전활동과 관련된 동기요인에 대한 우선순위를 알아보고, 건설근로자와 관리감독자 간의 인식차이를 확인하여 안전사고를 줄이기 위한 관리요소를 찾아보고자 하였다. 연구를 위하여 건설근로자와 현장 관리감독자를 대상으로 경제적 요인, 작업환경 및 안전 문화적 요인, 관리적 요인 등 3가지 상위 동기요인에 대한 21개의 세부요인으로 설문조사를 실시하였다 설문조사 결과 건설근로자와 관리감독자간 차이를 보이는 요인은 작업환경 및 안전 문화적 요인이 가장 크게 나타났다. 또한 현장에서 실시하는 안전인센티브는 건설근로자와 현장 관리감독자 모두 긍정적으로 생각하고 있다는 것을 확인하였다. 앞으로 본 연구결과를 바탕으로 근로자 중심의 관리를 통하여 안전사고를 줄일 수 있을 것이다.

The electrical accidents result from insulation blackdown due to over voltage and overheating due to the excess of allowable current, deterioration of insulation performance due to the passage of time, and so on. In this paper, the insulating characteristics of phenolic resin using insulating materials for low voltage were analyzed and the tracking test was performed according to IEC Publ. 112.

Thermal power plants play an important role in the country's power supply, but often violate the Industrial Safety and Health Act due to lack of safety awareness about the incompatibility of electrical safety and safety facilities. In this study, safety diagnosis was performed for each of the five major thermal power plants in Korea. For the 18 sites including coal, LNG, and power plants, we investigate the main violations of Article 327 and conduct intensive analysis on repetitive electrical safety violations to propose preventive measures that meet the characteristics of the power plant.

A SIL(Safety Integrity Level) assignment method is used for preventing failure action. The goal of safety system for processing automation is to reduce the human fatal risk. Even if we have developed the processing automation according to developing technology, we are also realized on increasing the human fatal risk cause of unexpected accidents. This study is directed the solution of decision for safety level for safety system and the best architecture for safety system in process automation.

The Electronic Interlocking unit in railway signalling system is safety-related facilities to determine route and speed for train running. In particular, the SSI(Solid State Interlocking) is Electronic Interlocking unit for high-speed railway, and it performs safety-critical function by MPM(Micro-Processor Module). Meanwhile, MPM is composed of the PES(Programmable Electronic System)-based system, and the PES-based system in railway safety-related facilities should be implemented by complying with the safety requirements defined in IEC 62425 and IEC 61508. In this paper, we performed modeling of failure rate and reliability for MPM implemented by fault tolerance methods and analyzed functional safety for MPM. Moreover, we determined SIL(Safety Integrity Level) for MPM according to the safety requirements defined in IEC 61508 based on an analyzed functional safety.
