  • Whenever a disaster occurs, people emphasizes that "Safety management is most important thing in the company". However, a situation of safety management is not changed dramatically after accidents in the past. Many small-and-medium sized industries neglect the importance of safety management. Current situation can be easily figured out when looks up an occurrence rate of accident, accident frequency rate and intensity rate. This paper investigated what workers of hotel-related industries think of a safety and types of accidents, effect of a safety education. On-site-survey was conducted for actual workers in four deluxe hotels and one condominium. 207 persons out of 400 people were replied. Statistical analysis was performed with SAS package about their reply. In injured type, cut from knife was most frequent. Main cause of accident was a unsafe posture and a unsafe behavior, so more safety education for these workers are necessary. In a physical pain which related with job, chronical pain was most dominant. As a result, a safety education has a high correlation with an experience of injured and treatment of safety, Cooking department has highest occurrence of accident than any other departments. Workers with an experience of five to ten years have most lowest treatment of safety, aid of safety education, safety feeling of their working environment, so peer attention must be put on these people to reduce accidents.accidents.

  • Accident rate in domestic construction industry has been increased rapidly in every year. In particular, the rate of death has been shown very high compared with other industries. It means that safety activities performed by government is not effective in reducing the rate of accident. To solve these problems, the risk factors should be predicted in advance, controlled, monitored and managed from start of project to end of project. However, most studies have been conducted by using frequency of occurrence of accident and only listed the importance of risk. Therefore, the objective of this study is to provide basic material to develop risk quantifying model for human accidents on construction site in South Korea. In the future, it is expected to be used as a reference of study on developing safety mangement checklist in construction industry and model for forecasting accident.

  • Background: Factors related to root causes can cause commonly occurring accidents such as falls, slips, and jammed injuries. An important means of reducing the frequency of occupational accidents in small- to medium-sized enterprises (SMSEs) of South Korea is to perform intensity analysis of the root cause factors for accident prevention in the cause and effect model like decision models, epidemiological models, system models, human factors models, LCU (life change unit) models, and the domino theory. Especially intensity analysis in a robot system and smart technology as Industry 4.0 is very important in order to minimize the occupational accidents and fatal accident because of the complexity of accident factors. Methods: We have developed the modern cause and effect model that includes factors of root cause through statistical testing to minimize commonly occurring accidents and fatal accidents in SMSEs of South Korea and systematically proposed educational policies for accident prevention. Results: As a result, the consciousness factors among factors of root cause such as unconsciousness, disregard, ignorance, recklessness, and misjudgment had strong relationships with occupational accidents in South Korean SMSEs. Conclusion: We conclude that the educational policies necessary for minimizing these consciousness factors include continuous training procedures followed by periodic hands-on experience, along with perceptual and cognitive education related to occupational health and safety.

  • Background: Students in the department of dental hygiene are exposed to injections and sharp instruments during clinical practice. Therefore, it is necessary to develop measures for a safe practice environment. This study aimed to investigate dental stabbing accidents caused by dental instruments during clinical practice among students in the department of dental hygiene and suggest appropriate preventative measures. Methods: This study was conducted from May 1 to June 30, 2016, with students in the department of dental hygiene located at several universities in Seoul and Gyeonggi area. The study included 339 participants. A frequency analysis was performed to determine the general characteristics of dental infection control. A cross-analysis was conducted to identify the relationship between dental infection control education, stabbing accident prevention education, and treatment after stabbing accidents with a dental instrument. Results: Among the participants, 81.1% received dental infection control education and 66.4% received stabbing accident prevention education. Only 50.9% received hepatitis B vaccinations. Conclusion: Dental infection control education and stabbing accident prevention education were shown to be effective in preventing dental instrument stabbing in students. However, post-accident processing, such as reporting to upper management and medical treatment after the accident, was insufficient. Therefore, it is necessary to present a treatment flowchart for dealing with stab accidents in clinical practice for students in the department of dental hygiene and strengthen education.

  • Simple statistical frequency based analysis, such as Pareto analysis, are widely used in conventional accident analysis. However, due to the dynamic and complex nature of construction works, many factors can simultaneously affect or involve the occurrence of accidents in construction projects. Therefore, the identification of the complex relationship between such factors is important to establish relevant and effective safety management policies and/or programs. In this study, characteristic factors and their relationships' contribution to non-fatal accidents in construction projects are analyzed using the association rule mining (ARM) technique. To this end, a total of 59,202 construction accident data are collected from 2015 to 2019 and the ARM is performed to retrieve specific relationships -named as association rules-among classified factors in the data. Characteristics of the retrieved relationships are analyzed and compared with the results of conventional Pareto analysis. Based on the results, it is found that both fall and trip are notable accident forms having characteristic relations with other factors for non-fatal accidents in construction projects. It is also found that small-scale construction, age of 50s, less than 1 month of working period, and architectural construction are important factors for non-fatal accidents in construction projects.

  • 화학사고를 예방하기 위한 장외영향평가서에서는 유해화학물질 취급시설의 화학사고 위험도를 산정하고, 적절한 안전성 확보방안을 확보하도록 유도한다. 위험도를 산정하는 방법은 '사고영향범위 내 주민 수'와 '취급시설의 사고발생빈도'의 곱이다. 현재 장외영향평가서에서는 사고영향범위 내 피해 유형으로 영향범위 내 주민 수만 고려하고 있고, 환경수용체에 대한 정량적 고려가 이루어지지 않고 있다. 본 연구에서는 환경수용체를 고려한 위험도 산정 방식을 제안하였고, 가상의 시나리오 분석을 통해 주민에 대한 고려만 이루어진 위험도와 환경수용체를 고려한 위험도 산정방식을 비교 분석하였다. 이러한 연구를 통하여, 화학사고 예방을 위한 장외영향평가 제도에서 중·장기적으로 환경수용체를 고려한 위험도 분석의 필요성을 확인하고 방법론을 제안하였으며, 향후 정책 및 제도개선의 기초자료로 활용하기를 기대한다.

  • In this study, the risk factors of coastal purse seine fisherman were analyzed through a survey of fishery workers of coastal purse seine fishery and the accident compensation insurance data of the fisheries workers of the National Federation of Fisheries Cooperatives (NFFC). The classified fishing operation accident data was analyzed through 4M (Man, Machine, Media, Management) model of the National Transportation Safety Board (NTSB) and the accident prevention measures were presented using Harvey's 3E (Engineering, Education, Enforcement) model. The rate of accidents on coastal purse seinens each year was 75.8‰, 36.7‰ and 74.8‰ from 2015 to 2017. The accident frequency resulting from slipping was the highest, and the risk of a contact with gear was low. When comparing each insurance data, the average value of the contact with gear accident was the highest. This research result is expected to be important data in identifying and preventing safety hazards of coastal purse seiner fisherman in the future.
