Korea Electrical Safety Cooperation(KESCO) have provided the electrical safety speed-call service from 2007 year. Purpose of the service is to reduce discomfort of electricity use and to prevent electrical accident like as electrical fire and shock accident by providing emergency treatment service on fault of the residential electrical facilities notified in the specific house like as a lower-income group and a social welfare facility. But efficiency and economic evaluation of the electrical safety speed-call service is impossible because analysis on the quantitative effect of the service is difficult. This paper presents cost-benefit analysis method and result of the electrical safety speed-call service. The presented cost-benefit analysis method has a two-step process: the first step is to measure quantitative electrical fire prevention effect of the service by using electrical accident statistics and developing outcome analysis logic model of the service effect, and the second step is to analysis cost-benefit(B/C)of the service by calculating quantitative benefit analysis on the measured quantitative electrical fire prevention effect. The results showed that cost-benefit(B/C)of the electrical safety speed-call service is over 4 after 2010 year.

Estimation of accident cost is a sound and great safety indicator on determining accurate occupational safety and health prevention. Just like in Korea, Heinrich ratio analysis of (1:4) between direct and indirect costs has been become widely used in safety management because of its simplicity. In this study four major categories of uninsured (indirect) cost items and 18 sub-categories of uninsured (indirect) cost items were identified. To determine and validate the importance and necessity of the results of a literature review an expert or professional surveyed had been analyses using the SPSS 18.0, where in the participants whose expertize is in the field of compensation and safety. Based on the results of survey all participants all uninsured (indirect) cost items classified was important and necessary when accidents occurred. Despite recognition of expert on the classification of uninsured (indirect) cost items, it is quite difficult to make generalization for all kind of costs in occupational accident case due to different nature of business for each industry.

In previous studies, a system was developed for classifying items of uninsured cost and for generating factors and formulas by item for calculating accident loss costs. However, the loss cost of stopped production was not considered when the system was being developed. In addition, the system which was developed in previous studies had problems such as input error and data collection, owing to numerous input items. Therefore, this study developed a Revised system which considers the loss cost of stopped production, and a Simple system for improving the problems in input errors and data collection. In this study, unquantifiable factors were not considered. Further study that takes these factors into consideration is necessary.

PURPOSE: The purpose of this study was to investigate the effect of a physical therapy-based tailored exercise program on pain, accident incidence rates, the number of work days lost, and economical loss cost for workers in an automobile parts manufacturing company. METHODS: A total of 530 workers with musculoskeletal symptoms were given a physical therapy-based tailored exercise program twice a week, for one hour a day. This exercise program consisted of movement pattern correction, muscle stretching and strengthening, and postural correction exercises, according to principles of movement impairment syndromes and medical training therapy. From 2011 to 2016, the lost days of work, accident incidence rates, and loss cost were examined. The pain measured by VAS (visual analogue scale) and the number of workers participating in the exercise program from 2014 to 2016 were also measured. The single subjects A-B design was applied and analyzed. RESULTS: After applying the exercise program, pain decreased and the number of workers participating in the program increased. Accident incidence rates, number of work days lost, and economical loss cost decreased. There was a significant correlation between the number of workers who received exercise therapy by year and accident incidence rates, lost days of work, and economical loss cost (p<.05). CONCLUSION: It is necessary to expand the physical therapy-based tailored exercise program to prevent musculoskeletal disorders because it has a positive effect on both workers and employers.

항로표지사고는 항로표지의 신뢰성을 저하시키고, 관리자는 추가적인 업무가 부여되며, 이용자는 항해 중 부담감을 가지게 되는 등 모두에게 불편을 초래하는 사회적 비용(경제적 손실)이 발생하게 된다. 이러한 항로표지사고로 인한 경제적 손실을 추정하기 위해 선행연구에서는 항로표지사고의 사회적비용 추정모델을 생산손실비용, 행정비용, 위험비용의 합으로 제안하였으나, 위험비용의 추정에 대한 적절한 연구결과를 제시하지 못하였다. 따라서 본 연구에서는 선행연구에서 제시한 추정모델을 보완하여, 부산청 관할해역에서 최근 10년간(2008-2017년) 발생한 항로표지사고 249건에 대한 사회적비용을 산출하였다. 즉, 항로표지 사고의 위험비용은 항로표지가 비시장재화이므로 조건부가치측정법을 이용하여 산출하였다. 그 결과, 10년간 항로표지사고의 사회적비용은 생산손실비용 31억원(25.38%), 행정비용 17억원(13.62%), 위험비용 75억원(61.01%) 등 총 124억원으로 추정되었다.

본 연구는 (예비)타당성조사의 교통사고 감소편익 산정방안에 관한 개선연구이다. 기존 방법론의 문제점은 크게 네 가지로 살펴볼 수 있다. 첫째, 인적피해사고 구분이 사상과 부상으로 단순화되어 있다. 본 연구에서는 현행 법 규정에 충실하게 도로는 사망, 중상, 경상 및 부상신고 사고로 구분하고, 철도는 사망, 중상 및 경상사고로 세분화한다. 둘째, 인명피해가 없는 단순 대물피해사고에 대한 고려가 미흡하다. 본 고에서는 대물피해사고를 사고유형의 하나로 명시적으로 고려하고 관련 사고비용원단위를 추정한다. 셋째, 사고비용 원단위가 단일 총액으로만 제시되고 있다. 사고비용을 구성하는 항목은 다양하므로 개별 항목은 특정 정책 수립 시 유용하게 활용될 수 있다. 본 연구에서는 사고비용을 생산손실비용, 의료비용, 물적피해비용 및 행정비용으로 세분화한다. 넷째, 도로와 철도의 사고비용 추정방안에 일관성이 결여되어 있다. 도로는 고속국도, 일반국도, 지방도 등 시설의 서비스 등급별 사고비용을 산정하는 반면 철도는 여객과 공중으로 구분하고 있다. 본 연구에서는 철도 서비스 등급별 사고건수 및 사고비용 원단위를 제시한다. 본 연구의 결과로 보다 합리적인 경제성 분석을 수행할 수 있음은 물론 궁극적으로 보다 신중한 사회기반시설 투자 정책 수립에 일조할 수 있기를 기대한다.

과속단속시스템은 지능형교통체계(ITS)의 한 영역인 첨단교통관리시스템(ATMS)으로서 중요한 역할을 수행하고 있다. 그러나 과속사고를 방지하기 위해 설치된 시스템이 시거가 확보되지 않은 구간이나 급커브 지역 등에 설치됨으로써 추가적인 교통사고 위험을 내포하고 있다. 이에 본 연구에서는 고속도로의 기하구조별로 시스템 설치위치를 구분하고, 각 위치에서 발생한 교통사고 자료를 시스템 설치 전 후로 나누어 기하구조별 과속단속시스템의 설치 전 후의 사고건수(Frequency), 대물피해환산법(EPDO, Equivalent Property Damage Only)을 통한 사고심각도와 사고비용(Accident Cost)을 분석하였다. 이와 같은 연구수행 절차를 통해 시거가 충분히 확보되지 않는 구간에서의 과속단속시스템의 설치가 사고에 미치는 영향을 알아보고 최종적으로 과속단속시스템의 설치위치에 따른 영향을 분석하고자 한다.

Recently, a massive loss of life and property is occurring in Korea due to traffic accidents, with the rapid increase in cars. For improvement of traffic safety, the Korea Transportation Safety Authority intensively analyzes accident data in local governments with low traffic safety index, performs a field investigation to extract problems and offers local governments improvements for problems, by conducting the 'Special Survey of Actual Conditions of Traffic Safety' each year, starting 2008. But local governments cannot strongly push forward the improvement projects due to the limited budget and the uncertainty of the improvement plan effects. Therefore, this study suggested a model which applied the Utility concept to the AHP theory, in order to efficiently decide a priority of the improvement plans in accident black spots in consideration of the limited budget of local governments. The number of accidents in each spot for improvement and accident severity, traffic volume, pedestrian volume, the improvement project cost and the accident reduction effect were chosen as evaluation factors for deciding a priority, and data about the improvement plan costs and the accident reduction effects, traffic accidents and traffic volume in the spots to undergo the special research on the real condition of traffic accident in the past were collected from the existing studies. Then, regression analysis was carried out and the Utility Curve of each evaluation factor was computed. Based on the AHP analysis findings, this study devised a priority decision method which calculated the weight and the utility function of each evaluation factor and compared the total utility values. The AHP analysis findings showed that among the evaluation factors, accident severity had the biggest importance and it was followed by the improvement plan cost, the number of accidents, the improvement effect, traffic volume and pedestrian volume. The calculated utility function shows a rise in utility, as the variables of the 5 evaluation factors; the number of accidents, accident severity, the improvement plan effect, traffic volume and pedestrian volume increase and a fall in utility, as the variables of the improvement plan cost increase, since the improvement plan cost is included in the budget spent by a local government.
