This study is to identify the factors affecting commuting time and modes in urban and rural areas using household traffic survey data. The findings indicated that commuting time using passenger car in rural areas was 1.6 times longer than those in urban areas. When citizen use public transportation, however, there was not much difference in commuting time in urban and rural areas. Among the various factors affecting commuting time in rural areas (13 factors have statistical significance), the most influential factors were that public transportation, managers and office workers, functional and device managers, and passenger car. In urban areas, the highly influential factors were public transportation and walking among the 16 affecting factors which have statistical significance. The commuting time in rural areas increased according to the occupation types, but the commuting time of full-time workers decreased. This phenomenom means that occupation groups with the full-time system prefer residential areas in the densely populated town.

화학공장에서 발생하는 사고의 발생원인은 다양하지만, 전 세계적으로 발생되는 산업재해의 96%는 근로자의 불안전행동에 의해 발생된다. 국제노동기구(International Labour Organization, ILO)에서는 근로자의 불안전행동에 의한 사고의 위험성을 경고하기 위하여 산업현장에서 다발적으로 발생하는 근로자의 불안전 행동을 20개의 요소로 구분하여 발표한 바 있으며, 산업재해 예방을 위해서는 근로자의 불안전행동을 제어하여야 한다고 강조하고 있다. 본 연구에서는 근로자의 불안전행동을 관리할 수 있는 방법을 알아보기 위하여 국내사업장의 사고조사 이력 정보를 토대로 현장에서 다발적으로 발생하는 주요 불안전행동 유형을 분석 하였다. 주요 불안전행동 분석 결과를 기반으로 Swiss Cheese Model을 이용하여 불안전 행동을 유발하는 근본원인을 분석하였으며, 각 근본원인별 관리방법을 제안하였다.

Background: This study examined age-group differences in the rate, severity, and cost of injuries among construction workers to support evidence-based worker safety and health interventions in the construction industry. Methods: Ohio workers' compensation claims for construction workers were used to estimate claim rates and costs by age group. We analyzed claims data auto-coded into five event/exposure categories: transportation incidents; slips, trips, and falls (STFs); exposure to harmful substances and environments; contact with objects and equipment (COB); overexertion and bodily reaction. American Community Survey data were used to determine the percentage of workers in each age group. Results: From 2007-2017, among 72,416 accepted injury claims for ~166,000 construction full-time equivalent (FTE) per year, nearly half were caused by COB, followed by STFs (20%) and overexertion (20%). Claim rates related to COB and exposure to harmful substances and environments were highest among those 18-24 years old, with claim rates of 313.5 and 25.9 per 10,000 FTE, respectively. STFs increased with age, with the highest claim rates for those 55-64 years old (94.2 claims per 10,000 FTE). Overexertion claim rates increased and then declined with age, with the highest claim rate for those 35-44 years old (87.3 per 10,000 FTE). While younger workers had higher injury rates, older workers had higher proportions of lost-time claims and higher costs per claim. The total cost per FTE was highest for those 45-54 years old ($1,122 per FTE). Conclusion: The variation in rates of injury types by age suggests that age-specific prevention strategies may be useful.

우리나라에서 화물 수송분담율을 가장 많이 차지하는 것이 도로운송이다. 도로 컨테이너 운송은 컨테이너 운송의 출발점이자 완결점일 뿐만 아니라 매우 복잡하고 종사자 또한 많다. 육상물류에서 핵심 역할을 하고 있는 컨테이너 운전기사의 본업은 컨테이너를 항만 및 터미널에서부터 목적지까지 운송해 주는 것이다. 그러나 운송과정에서 컨테이너의 청소 및 데미지 컨테이너의 관리 등 본업외에도 여러 가지 컨테이너 관리의무를 묵시적으로 전가받고 있는 실정이다. 그러나 동 사안에 대해서는 그동안 거의 연구가 되고 있지 않은 상황이다. 본 연구는 컨테이너 운전기사의 근로환경에 대해 파악하고, 컨테이너 관리 작업에 대한 실태와 현황을 실증적으로 분석했다. 나아가 선사, 터미널, 화주별로 컨테이너 관리 요구 정도의 차이가 있는지 분석하는 한편 조사지역별 요구사항의 차이를 분석하고, 컨테이너 관리 전가문제에 대한 개선방안을 제시하였다.

Currently, in Korea, an accident that takes place during a worker's commuting is generally not considered as work-related accident. However, there are several exceptions such as an accident that occurs in commuting while using transportation provided by an employer, an accident that happens during commuting time that can be regarded as part of a business activity (e.g. tending to work instructed by an employer on the way to or from work), and an accident that is caused by insufficient facility management by an employer. It is even more so as the workers' commuting distance increases with expanding scale of a city, and traffic accident occurs more frequent. Social risk of commuting-time accident is on the rise. Under this circumstance, it is an important social issue to explore how to protect workers from commuting-time accident.

It is necessary to have a maintenance of track and its equipment for safety and s the railroad transportation. In the paper, we examine the safety problems, protecti and composition of protection system for safety within the track which RTRI develo system consists of a mobile business tool carried by each worker. a terminal of t platform temporarily installed in the maintenance car. a connector attached to signalling system and a central administrative device installed at the control cen used independently to detect positions of workers and maintenance cars. Each m correctly grasp the geometrical relations with other workers cars and other objects conditions based on the state information exchanged between the machines by the control protocol. the track occupancy monitor information broadcast by th administrative device and the line information. The protection system executes its f this basic structure.

It is known that human factors account for 80 percent of all railway accidents. To reduce human errors must be the most efficient shortcut to railway safety. For public transportation employees like railway, the more delicate safety management should be executed in individual level. However, there are rarely efforts to improve safety performance of workers who are the subject operating the railway system. This paper develops a hierarchy model to evaluate the human safety performance in railway industry. To evaluate the model, AHP (Analytic Hierarchy Process) methodology is adopted. The hierarchy model is composed of four levels which are objective, two criteria, specific factors of criteria, and rating scales. In addition, since employees for evaluation are over 10, the pairwise comparisons for rating scales are carried out by the absolute measurement. We explore the applicability of AHP to the performance evaluation of railway safety workers by an example and also investigate the changes of alternatives that are railway employees according to the changes of human characteristic which is one of criteria.

화학 관련 산업에서의 중대재해 발생 사고를 업종별로 분류하여 방호시설, 설비결함, 기인물 및 불안전 행동 그리고 고용형태 등에 대한 영향을 살펴보고자 하였다. 이에 다음과 같은 결과를 얻었다. 첫째 화학 관련 업종 중에서 화학물 및 화학제품 제조업이 중대재해자 수가 가장 많은 것을 알 수 있었고, 그 중에서도 특정방호시설에 집중되고 있는 것을 파악하였다. 둘째 고용형태에 따른 중대재해는 주로 임시직 및 일용직이 아닌 상용직 경력자들에서 일어나는 것을 알 수 있었으며 피해 형태는 주로 대형사고로 인한 4명이상 사망자가 발생하는 피해가 발생하는 것으로 파악되었다.

Decommissioning of nuclear power plants generates a large amount of radioactive waste in a short period. Moreover, Radioactive waste has various forms including a large volumes of metal, concrete, and solid waste. The disposal of decommissioning waste using 200 L drums is inefficient in terms of economics, work efficiency, and radiation safety. Therefore, The Korea Radioactive Waste Agency is developing large containers for the packaging, transportation, and disposal of decommissioning waste. Assessing disposability considering the characteristics of the radioactive waste and facility, convenience of operation, and safety of workers is necessary. In this study, the exposure dose rate of workers during the disposal of new containers was evaluated using Monte Carlo N-Particle Transport code. Six normal and four abnormal scenarios were derived for the assessment of the dose rate in a near surface disposal facility operation. The results showed that the calculated dose rates in all normal scenarios were lower than the direct exposure dose limitation of workers in the safety analysis report. In abnormal scenarios, the work hours with dose rates below 20 mSv·y^-1 were calculated. The results of this study will be useful in establishing the optimal radiation work conditions.
