연구목적: 국내의 차량 등록 대수는 계속 증가하고 있다. 삶의 질 향상으로 인한 교통량 또한 점진적으로 증가하므로 사고 심각도가 증가 및 혼잡문제 또한 야기될 것으로 예상된다. 따라서, 첨두 교통사고와 비첨두 교통사고의 사고 요인을 분석할 필요가 있다고 판단된다. 연구방법:인천광역시의 첨두 및 비첨두 교통사고의 심각도를 첨두와 비첨두로 나누어 분석하여 사고에 영향을 미치는 요인을 알아보고자 한다. XGBoost 머신러닝 기법을 적용하여 첨두 및 비첨두 교통사고 심각도를 분석하였으며 결과를 통하여 plot으로 시각화하였다. 연구결과:첨두시 피해운전자 차종_승합인 경우 등 비 첨두시는 피해운전자 차종_건설기계 등이 사고 심각도를 높이게 되는 변수인 것으로 분석되었다. 결론: 첨두와 비첨두 사고 심각도의 요인을 도출한 것에 의의가 있고 추후 첨두 및 비첨두시의 사고 심각도를 낮추고 국내 교통의 혼잡 요인을 분석하여 혼잡 비용을 줄일 수 있는 것에 활용되기를 바란다.

Studies on 66 industrial accidents happened in a battery manufacturing industry during a year of 1973 were carried out. The results obtained are follows, 1. Majority of employees of this industry was occupied by yong woman aged between 20-24. 2. Incidence rate, frequency rate and severity rate of the accidents was 36.8 per 1,000, 12.8 per 100,000 labour day and 0.3% respectively. Anual average days of lost due to accidents was 18.0 days. 3. Accidents happened more frequently in male than female, and happened most frequently in age between 30-34. 4. As to type of work, 47.9% of the accidents happened on hand operating workers. This was the same in both sex. 5. Accidents happened mainly during 2-3 hours latter from work starts in both morning and afternoon work, 6. 63.6% of the accidents happened on hands in both sexes and followed by lower extremities. 7 Surface wounds like as laceration, cut and abrasion were the main types of injury occupying 31.8% and followed by burn at 24.2%. 8. 54.5% of accidents needed 1-2 weeks to heal the injury and heavy injury needed more than 5 weeks was only 9.1%. 9. Accidents happened most frequently in employees who served between 2-3 years in this industry, but observing of sex difference. it was most frequent in male who served more than 4 years whereas less than 6 months in female.

항로표지는 선박의 위치·방향 및 장애물의 위치 등을 알려주는 항행보조시설로써 중단없는 서비스가 중요하다. 본 연구는 서비스의 중단을 야기하는 항로표지 사고를 분석하고 사고와 관련된 주요 요인을 도출하는 것이 목적이다. 이를 위해 2000년부터 2022년까지 발생한 항로표지 사고자료를 활용했다. 항로표지 사고의 변수를 사고유형, 원인, 지방청, 계절, 항로표지 유형으로 구분했으며, 상관관계 분석을 통해 네트워크를 도출했다. 항로표지 사고 기반으로 도출한 베이지안 네트워크에 사전확률을 부여하고, 항로표지 사고 유형별로 발생 확률을 높이는 요소들을 도출했다. 도출된 결과는 신고되지 않은 항로표지 사고의 원인을 추론할 수 있으며, 항로표지 사고 예방을 위한 기초 자료로도 사용할 수 있다.

LPG-related accidents, which account for half of all gas accidents in Korea, have not shown any sign of decrease over the past decade, partially owing to the lack of effective safety improvement measures. The purpose of this study was to identify the effectiveness of improvement measures by analyzing the traits of accidents in terms of human factors, and to seek more effective accident prevention strategies. In this study, 108 accident cases were collected and analyzed in the aspect of accident characteristics such as violation type, human factors, and so on. The results showed that the work procedures of suppliers and engineers related to LPG accidents seemed to be similar in outward appearance; however, specific accident causes and unsafe behaviors were different. Particularly, type and target of violations were different, which could be visually confirmed by the Principal Component Analysis (PCA) and the Quantification Techniques (QT). Furthermore, for engineers, insufficient supervision was a major influencing factor. In conclusion, because the accident characteristics of suppliers and engineers are different, differentiated accident prevention strategies should be implemented, which was discussed in this study.

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.

Construction work accidents have not decreased in spite of much effect such as new work methods education and research related to the safety management. Specially, many fatal accidents were mainly caused by unanticipated risk factors in reinforced concrete construction work, which was involved in apartment, building. school church, hotel hospital, bank work and the other works. According to the construction fatal accident book by KOSHA 1,903 workers were killed by the fatal accidents in reinforced concrete construction work during the 13 years$(1992\~2004)$. From these reasons, this study researched the cause of fatal accidents which were happened in reinforced concrete construction work during last 13 years and surveyed construction managers and specialists about risk factors according to the work type in the reinforced concrete construction work. Therefore, this study will suggest the counterplan about the construction safety management and prevent fatal accidents from construction site related to the reinforced concrete construction work.

The dental accidents and disputes among Korean dentists have been on the increase with time. The main purpose of this study is to figure out the actual status of the dental accidents and malpractice disputes based on a questionnaire survey. The findings showed that 64.8% of respondents had been experienced the dental accidents, and 52.9% of respondents had been locked into the disputes. Within 5 years from the start of dental practice, the nearly half of the dentists responded the experience of the dental accidents and disputes. The amount of compensation for dental accidents and disputes wereindentalimplant, prosthodontics, and oral surgery treatments in descending order. The highest incident type was wrong process/treatment/procedure problem in clinical process/procedure.

Allergic diseases as the major symptoms of Sick Building Syndrome have significantly increased because of the indoor pollutants resulted from the enhanced energy conservation performances of residential buildings. Following traffic accidents, domestic accidents are known as the second most frequent accident type. This study analyzes the occurrences of allergic diseases and home accidents caused by housing conditions, together with the residents' consciousness of the diseases and accidents. The findings of this study are expected to help develop the design guidelines and new housing types conducive to the healthy housing environment. For this study, a questionnaire survey was conducted in two rounds which include face-to-face questionnaire survey and online survey, collecting 200 responses and 1000 responses respectively. The data based on the valid 1011 responses were analyzed by Frequency Analysis and T-test.

This study aims to develop the traffic accident models by circular intersection type using count data model. The number of accident, the number of fatal and injured persons(FSI), and EPDO are calculated from the traffic accident data of TAAS. The circular intersection accident models are developed through Poisson and negative binomial regression analysis. The main results of this study are as follows. First, the null hypotheses that there are differences in the number of traffic accidents, FSI and EPDO by type of circular intersections are rejected. Second, the scale of intersection(median, large), number of approach road, mean width and length of exit road, area of the circulating roadway and central island are selected as factors influencing the number of traffic accidents, FSI and EPDO in rotary. Third, the scale of intersection(median), guide signs(limited speed, direction, roundabout), number of approach road, entry angle, area of the intersection and central island are adopted as factors influencing the number of traffic accidents, FSI and EPDO in roundabout. Finally, transferring from rotary to roundabout could be expected to make the accident decrease.
