본 연구에서는 경기도 일대 2곳의 대형 아파트 현장의 외국인 작업자 165부의 유효 설문지를 바탕으로 외국인 작업자들의 습관적 행위, 공격성, 상황회피, 심리불안 요인이 위험행동과 안전사고 위험지수에 미치는 영향 관계를 가설검증을 통해 습관적 행위, 공격성, 상황회피 및 심리불안 요인은 위험행동에 영향을 미치는 것으로 나타났으며, 습관적 행위 요인은 안전사고 위험지수에도 영향을 주는 것으로 나타났다. 하지만 공격성, 상황회피, 심리불안 요인은 안전사고 위험지수에 유의한 영향을 미치지 않는 것으로 나타났다. 그러나 위험작업 행동은 안전사고 위험지수에 유의한 영향을 미치는 것으로 나타나 개인적인 성향과 연관이 있는 습관적 행위, 공격성, 상황회피 및 심리불안의 상태가 위험작업으로 발전할 수 있고, 이러한 위험작업행동은 안전사고로 이어질 수 있는 결과를 알 수 있었다. 따라서 외국인 건설현장 작업자의 증가로 인한 안전사고의 증가 문제는 외국인 작업자 때문이기 보다는 외국인 작업자 개인의 성향에 초점을 둘 필요성이 있다고 판단되며, 각 사업장에 직접 투입된 외국인근로자의 성향분석과 그에 따른 개선방안을 도출하면 사고를 줄일 수 있을 것으로 생각된다.

하천 유량측정은 대부분의 업무가 야외에서 진행되기 때문에 사고위험에 항상 노출되어 있다. 특히. 교통, 수상안전 사고 등 사회적 안전사고에 대해서는 큰 노력을 기울여 대비하고 있으나, 폭염, 한파 등 자연적 안전사고에 대해서는 아직 대비가 미비하다. 본 연구에서는 겨울철 한파로 인해 발생할 수 있는 안전사고를 예방하고자 한파위험지수(CWRI)를 PSR 구조체계를 통해 제안하였다, 압력, 상태, 반응 지수 산정을 위해 각 요인에 대한 세부지표를 선정하고, 각 지수에 대한 가중치는 엔트로피 방법을 이용하여 한파위험지수를 제안하였다. 그 결과, 전국 14개 광역시도 중 서울특별시가 가장 높고 경상남도가 가장 낮은 한파 위험지수를 보였다. 이러한 결과를 토대로 겨울철 유량측정 시 측정 인원에 대한 안전 계획을 수립하여 안전사고 예방 효과를 높일 것으로 판단된다.

In 2017, the ratio of the number of victims and deaths in the construction industry was the highest with 25.2% and 29.6%, respectively. Especially, as safety accidents at construction sites continue to increase, the economic loss is greatly increased too. Therefore, in order to prevent safety accidents in the construction work, the safety risk assessment index by type of construction was developed, and the main results of this study are as follows. First, 17 factors related to safety accidents at construction sites were derived through survey and interview survey, and this study suggested 9 items(process, type of construction, progress rate, contract amount, number of floors, safety education, working days and weather) throughout the expert advisory meeting. Second, the risk assessment index for safety accidents was developed based on the ratio and intensity of safety accidents. Third, to verify the risk assessment model, the construction safety risk assessment index by type of construction was derived by surveying and analyzing the statistics of the construction accident. In addition, the risk strength was calculated by dividing human damage caused by construction safety accidents into those killed and injured. The risk assessment index based on the frequency and intensity of safety accidents by type of construction is expected to be utilized as basic data when assessing the risk of similar projects in the future.

Recently, buildings have become larger, more complex, and various construction methods have been tried. As a result, the use of construction equipment continues to increase, as well as safety accidents. According to the Ministry of Employment and Labor's report on industrial accidents, the rate of deaths caused by construction equipment among construction accidents has been increasing steadily since 2009. In the safety field of other industries such as crime and traffic, research has been continuously conducted to develop quantitative indicators due to demands for development of evaluation indicators or risk index development. On the other hand, construction equipment has been studied to analyze disaster cases and come up with improvement measures, but there is no research related to risk index. Therefore, the research will develop a quantitative index that can determine the risk level of construction equipment in the field based on the accident case and verify the possibility of use in the field.

우리는 복잡한 현상을 하나의 수치로 표현하는 각종 지표(index)를 생활에서 많이 접하고 있다. 종합주가 지수, 불쾌지수, 소비자 물가지수, 년간 교통사고 건수, 인구 10만명당 교통사고 사망자수 등도 일종의 지표라 할 수 있다. 철도에서도 위험을 평가하는 지표로는 "년간 사고건수", "열차운행 100만-km당 사고건수"와 같이 발생빈도에 초점을 둔 경우와 "년간 사망자수", 혹은 "피해액", "운행지장"과 같이 사고피해에 초점을 둔 경우가 있다. (중략)

Risk elements of highway safety facilities are affected by complex environments. Thus, risk-based approach for traffic safety facilities is needed. For this, in this study, qualitative and quantitative risk assessment methodology and procedure for highway safety facilities is proposed, which can be used as risk-based approach incorporating VE process. Also, for the quantitative risk assessment, event tree using EPDO(Equivalent Property Damage Only) with respect to frequency and magnitude of risk events is introduced. As a result, risk index of alternative 1(140cm) and 2(127(cm) which can be used as performance factor in VE approach are estimated.

A traffic accident analysis method was developed and tested based on the highway alignment risk indices using geographic information systems(GIS). Impacts of the highway alignment on traffic accidents have been identified by examining accidents occurred on different alignment conditions and by investigating traffic accident risk indices(TARI). Evaluative criteria are suggested using geometric design elements as an independent variable. Traffic accident rates were forecasted more realistically and objectively by considering the interaction between highway alignment factors and the design consistency. And traffic accident risk indices and risk ratings were suggested based on model estimation results and accident data. Finally, forecasting traffic accident rates, evaluating the level of risk and then visualizing information graphically were combined into one system called risk assessment system by means of GIS. This risk assessment system is expected to play a major role in designing four-lane highways and developing remedies for highway sections susceptible to traffic accidents.

에너지분야 국가핵심기반시설에서 산업재해 및 업무중단 사고예방을 위해 재해경감활동관리체계(BCMS)에서 일일위험지수 재난안전관리 프로그램을 자체개발 운용하여 정부의 중대재해 감축 로드맵의 핵심적인 4대 전략 중 하나인 사업장에서 유해위험요인에 대한 자기규율적인 예방관리체계의 확립한 사례를 제시하였다. 이에 대한 신뢰성 검증을 위해 중대산업재해 감축효과에 영향을 미친 사업장의 BCMS, 일일위험지수 및 중대재해처벌법 간의 관계성을 연구한 결과, 제도 간 개념의 관련성이 높으며, 상호 보완적이고 영향을 미치는 것으로 확인되었다. 따라서 동종 사업장에서 재해경감활동관리체제의 일일위험지수를 활용한다면 중대재해예방관리에 도움이 될 것으로 기대된다.

This study was conducted to derive the traffic accident risk index through the recognition of the elderly driver's driving pattern to reduce the traffic accident rate of elderly drivers and to reflect them in the renewal and return policy of driver's license accordingly. First, the traffic accident risk index is defined by analyzing the behavioral characteristics of older drivers to derive the major factors that lead to traffic accidents. Second, we present a method to measure the traffic accident risk index from the driving pattern of the elderly through the smart-phone, the camera and the distance sensor attached to the car. Finally, we derive three thresholds by computer simulation and determine the accident risk from the measured traffic accident risk index as four steps and suggest ways to ensure safe driving of older drivers. It is required to objectively assess the driving ability of an aged driver in accordance with the proposed method, and to induce the driver to reset the driver's license renewal cycle and voluntarily return the driver's license to minimize social costs due to increased traffic accidents.
