도로설계 안전성을 평가하기 위해서는 도로의 설계 요소변화가 사고에 미치는 영향을 예측할 수 있어야 한다. 이를 위해 본 연구에서는 통계적 방법, 사고이력, 전문가의 판단, 그리고 기존문헌고찰 등 다양한 방법을 통하여, 설계요소의 특징과 사고율 및 사고빈도의 관계를 반영할 수 있는 AMF(Accident Modification Factor)를 개발하고자 하였다. 본 연구에서는 AMF를 좌회전전용차로, 우회전전용차로, 시거, 교차각 등의 항목을 대상으로 개발하였다. 개발된 AMF를 적용한 경우의 사고 예측값, 사고예측모형을 통한 예측값을 실제 사고데이터와 비교분석함으로써 적정성을 검토하였다. 분석결과, AMF를 적용한 예측값이 사고예측모형을 통한 예측 값보다 예측력이 우수함을 확인할 수 있었다. 이러한 결과는 사고를 예측함으로써 도로설계 안전성을 평가하는 알고리즘에 있어 AMF가 도로의 설계요소의 특성을 보다 효과적으로 반영하며, 지방부 교차로에서 각각의 해당요소가 사고에 미치는 영향을 판단할 수 있는 지표가 될 수 있음을 의미한다.

Background: Fisheries and aquaculture are statistically acknowledged to be among the most dangerous occupations. Yet, industrial safety and health precautions against occupational accidents within the sector are not sufficiently implemented in many parts of the world. The present study aims to provide a quantified overview of work accident statistics in the Turkish fisheries and aquaculture industry. Methods: This article presents an overview of reported injuries and fatalities in the Turkish fisheries and aquaculture industries from 2006 to 2020. Incident, permanent incapacity, and fatality rates were calculated, and the difference between fisheries and aquaculture was statistically examined. Results: The overall incident, permanent incapacity, and fatality rates were 449.4, 4.7, and 5.7 per 100,000 worker years, respectively, over the 15-year period. With these fatality rates, fisheries and aquaculture are two of the industries with the highest fatality rates among comparable industries in Turkey. Incident rates in fisheries and aquaculture indicated that aquaculture work is more dangerous and risky. The data set includes 25 fatalities and 22 permanent incapacity cases over 15 years and shows an increase in fatality rates and occupational accidents in the last 8 years. Conclusion: present study showed that the quality of data and reporting in the Turkish fisheries and aquaculture industries including occupational illnesses, must be improved in order to be more preventative and to develop efficient safety management in the sector. Incentives for providing thorough data on occupational incidents must be enhanced to improve occupational safety awareness in Turkish fisheries and aquaculture.

Korea is becoming an aged society as well developed country. Accident rates of elderly workers are increased. When elderly workers injured, elderly workers are more likely to die as a result, and they take longer to recover than young workers. Thus the cost to industry per individual accident gets higher for elderly workers. If information on the occupational accidents of elderly workers could be collected and analyzed for the purpose of preventing occupational accidents, we would be able to get rid of accidents of elderly workers. The accidents of elderly workers in small manufacturing factories were considered in this study. 97 accidents, which occurred in 1995-1998, were investigated. These accidents were analyzed in terms of sex, work period, cause of accident and form of accident. The accidents of elderly workers in small manufacturing factories are numerous and are often serious and worthy of greater attention than they have received. Successful strategies for accident prevention depend on effective analysis.

As the size of construction projects has become larger in recent years, the nature of the disaster safety factors along with the progress of construction is also becoming more complex and diversified. Accordingly, the introduction of computerized construction, new technologies, and new construction methods has resulted in a variety of risk factors in the process and operations, and many new safety construction methods are being tried. Since the construction industry has variable working environments and constantly changes working methods and components depending on the rate of progress, workers at construction sites are always exposed to risk depending on the specific circumstances of the construction industry. This study attempts to collect and analyze major accident cases generated by major accident construction projects as a result of progress in construction work, and to derive the major causes and causes for each safety management activity that affect safety accidents.

Lessons learned from the Fukushima Daiichi nuclear power plant accident directed that multiple failures should be considered more seriously rather than single failure in the licensing bases and safety cases because attempts to take accident management measures could be unsuccessful under the high radiation environment aggravated by multiple failures, such as complete loss of electric power, uncontrollable loss of coolant inventory, failure of essential safety function recovery. In the case of the complete loss of electric power called station blackout (SBO), if there is no mitigation action for recovering safety functions, the reactor core would be overheated, and severe fuel damage could be anticipated due to the failure of the active heat sink. In such a transient condition at CANDU-6 plants, the seal failure of the primary heat transport (PHT) pumps can facilitate a consequent increase in the fuel sheath temperature and eventually lead to degradation of the fuel integrity. Therefore, it is necessary to specify the regulatory guidelines for multiple failures on a licensing basis so that licensees should prepare the accident management measures to prevent or mitigate accident conditions. In order to explore the efficiency of implementing accident management strategies for CANDU-6 plants, this study proposed a realistic accident analysis approach on the SBO transient with multiple-failure sequences such as seal failure of PHT pumps without operator's recovery actions. In this regard, a comparative study for two PHT pump seal failure modes with and without coolant seal leakage was conducted using a best-estimate code to precisely investigate the behaviors of thermal-hydraulic parameters during transient conditions. Moreover, a sensitivity analysis for different PHT pump seal leakage rates was also carried out to examine the effect of leakage rate on the system responses. This study is expected to provide the technical bases to the accident management strategy for unmitigated transient conditions with multiple failures.

Purpose: The purpose of this study was to examine the health care management status of preschoolers depending on the children's characteristics. Methods: The sample of this study were 212 mothers of preschoolers attending Child Care Centers in three cities, Seoul, Daejon, and Suwon, in Korea. A self administered questionnaire developed by investigators was used to collect data from September 15 to October 31, 2002. Data was analyzed with SPSS 11.5 Win program. Results: 5.7% of the children had not completed their vaccination programs. Children who were second or later birth order showed less complete vaccination rates than firstborn babies. Children who had working mothers showed less complete vaccination rates than those whose mothers did not work. Among the various vaccinations, the DPT and MMR booster vaccination rates were the lowest. Home safety scores were higher when mothers have younger children. higher monthly incomes and reside in apartment type houses. Forty one(41%) of the preschoolers experienced accidents, and the accident rate was higher in boys and children with easy temperament. The most frequently experienced accident was laceration. Twenty eight point eight percent(28.8%) of the children experienced hospitalization because of various diseases. Most of the mothers perceived their children healthy. However, children who were second or third born were perceived less as healthy. Children in families with less monthly income were perceived as less healthy. Conclusions: This study provided basic data about preschoolers' health care management status focusing on vaccinations and accident rates. More attention should be paid to preschoolers' health and safety. Related factors found in this study should be considered when providing anticipatory guidance for parents.

Among all industries, the construction industry still remains a traditional one with low productivity due to its labor-intensive and field-dependent production system, its supplier-oriented industrial structure, and the disruption of the information flow between participants. In addition, the construction industry in South Korea has recently been required to transform itself according to social trends such as aging, the reduction of skilled workers, and the shortening of working hours, and the disaster and death rates in the industry, which are more than twice as high as those in other industries, are making it more necessary to solve chronic safety problems. Therefore, the purpose of this study is to grasp the actual condition of safety management on construction sites in South Korea and analyze cases of K-smart technology utilization for preventing safety accidents on construction sites. The study investigated and analyzed the following. First, construction sites in South Korea were analyzed by type of safety accident, by type of construction, and by construction contract amount. Second, the current status of accidents on small-sized construction sites with a high fatal accident rate and cases of safety accidents on construction sites were investigated. The results of the study are expected to contribute to the dissemination and spread of smart safety technology for not only identifying major factors in safety accidents that occur on construction sites but also preventing workers from suffering accidents.

지역단위 도로교통안전도에 대한 거시적 평가는 인구, 자동차대수, 도로연장 등의 거시적 노출변수(Macroscopic Exposure Measures)에 기반한 사고율을 노출지표로 이용하는 것이 일반적이나, 노출지표를 이용한 도로교통안전도 평가에 노출지표들이 미치는 영향이 각기 다르기 때문에 결과적으로 각각의 개별노출지표별 평가시 평가결과가 서로 상이하게 되는 문제가 있으며, 이는 예산투자의 효율적 집행을 위한 교통안전정책의 결정과정에 방해요인으로 작용하게 된다. 따라서 본 연구에서는 최소제곱법 및 가중치를 일정단위로 변화시키는 시뮬레이션을 이용하여 노출지표별 최적의 가중치를 도출하였으며, 이를 종합적으로 반영할 수 있는 도로교통안전도 비교평가지수 산정방법을 개발하였다. 지수를 구성하는 노출지표별 가중치는 인구당사고율이 0.29, 자동차등록대수당사고율이 0.52, 도로연장당 사고율이 0.19로 도출되었으며, 개발된 방법을 적용하여 전국 기초지자체별로 도로교통안전도 비교평가지수를 산정하였다. 본 연구에서 제시한 방법을 통해 노출지표별로 평가결과가 상이해지는 문제를 해결할 수 있으며, 교통안전예산의 투자효율성을 높이기 위한 교통안전정책의 합리적인 결정방법으로 활용될 수 있을 것으로 판단된다.

Compared with past, helicopters have remarkably high level of safety and accidents due to mechanical defects are decreased about 15%. Most of their duties, however, are to commit at duty area which is hard to access. Because of them, collision probability is high and also has relatively higher accident rates than other aircraft with special mission. A result of analysis is that accident rate is relative high with prevention of disasters, putting out a fire and crop-dusting missions under 500ft. In addition, most of accidents are related with human factors. According to this, it is required to pilots who carry these mission that safety education and detailed analysis about their mission.
