Clinical observations were performed on 150 cases of chest trauma, those were admitted and treated at the Department of Surgery, Korea University Woosok Hospital, during the past 8 years period from August 1965 to August 1972. 1. The ratio of male to female patient of chest trauma was 3.4:1 in male predominence and age from 20 to 50 occupied 62% of the total cases. 2. The most common cause of chest trauma was traffic accident in this series. Eighty-one cases[54%] were injured by traffic accident and total cases due to blunt trauma [non-penetrating injury] were 113 cases[75.4%]including the cases with traffic accident, and remaining 37 cases[24.6%] were due to penetrating injury including 25[16.6%] cases of stab wounds. 3. Hemopneumothorax were observed in 645/[96 cases] of the total cases, and etiologic distribution revealed 78.1% due to non-penetrating trauma and 20.8% due to penetrating injury. 4. Rib fracture was found in 50% of cases. Common injuries associated with rib fracture were lung, brain and liver. 5. Most common symptom was chest pain and respiratory difficulty, and common sign associated with chest injury was decreased respiratory sound and subcutaneous emphysema. 6. Conservative non-operative treatment was performed in 94 cases[62.6%] and 56 cases [37.4%] were treated with operative treatment including 31 cases[20.6%] with open thoracotomy. 7. Overall mortality was 9.3%[14 cases] and most common causes of death were due to brain edema,asphyxia and shock.

Developed in the study is the analysis of human factors involved in accidents of Korean Construction Projects. The 556 cases are sampled from a survey material 'Serious Accident Cases in the Construction Projects' edited by Korea Industrial Safety Corporation in 1995 through 1997. The analysis of these cases shows that existing classification system is not good for practical applications in real spots since they are difficult for engineers to understand. In this paper, human factors are classified into three groups by extracting the analysis and arrangement of the cases. Futhermore, We'll propose here a new type of accident which is subdivided. If engineers use this type of accident, they will be probably able to analyze efficiently human factors which are involved in accidents and relatied with how it happen. In the case of fall and upset accidents, personal factors seem to be critical when workers are horizontally moving in an unstable manner, and vertically moving without boarding facilities. Futhermore work environmental factors are important when workers release some materials and are performing building and dismantling tasks.

The present study has investigated the patterns and the causes of safety -accidents on the accident-data in semiconductor Industries through near miss report the cases in the advanced companies. The ratio of incomplete actions to incomplete state was 4 to 6 as the cases of accidents in semiconductor industries in the respect of Human-ware, Hard- ware, Environment-ware and System-ware. The ratio of Human to machine in the attributes of semiconductor accident was 4 to 1. The study also investigated correlation among the system related to production, accident, losses and time. In semiconductor industry, we found that pattern of safety-accident analysis is organized potential, interaction, complexity, medium. Therefore, this study find out that semiconductor model consists of organization, individual, task, machine, environment and system.

대학 실험실이나 연구시설에서 실험실 사고에 의해 인적 및 물적 손실이 꾸준히 발생되고 있어서 실험실 사고예방의 필요성이 제기되고 있다. 실험실 사고예방을 위해 무엇보다 중요한 것은 사고의 체계적인 분석이다. 국내에서 산업재해에 관한 분석 연구는 수행되어 왔으나, 실험실 사고 분석에 관한 연구는 수행되지 않았다. 본 연구에서는 실험실 사고예방 대책 수립을 위해 설문지를 개발하였고, 설문지는 대학과 연구기관에 전자우편이나 방문조사로 사고사례를 수집하였다. 사고사례 데이터는 계절별, 사고 분류형태, 발생형태, 기인물 및 상해종류 별로 분석 고찰하였다. 이 연구결과는 실험실 종사자의 안전 확보와 사고예방을 위한 기초자료로 활용하고자 하였다.

According to Meridian Muscle theory, a injured parts of patient were devided as follows. There were 22cases(59.46%) which have injury in Bladder, Small Intestine Meridian Muscle, 10cases(27.03%) in Gallblader, Triple Energizer Meridian Muscle, 5cases(13.51%) in Stomach, Large Intestine Meridian Muscle. 5. There were 6cases(16.22%) of the grade of complete recovery, 10cases(27.03%) of the grade of excellent, 12cases(32.43%) of the grade of improvement, 6cases(16.22%) of the grade of disimprovement and 3cases(8.11%) of the grade of poor. So 28cases(75.68%) were efficacious. 6. Generally Herb-meds that have efficacy of Geo-Eohyeol were most used(27cases, 72.97%) in early stage. Secondly Herb-med that have efficacy of Yiqi-sunqi were used(20case, 54,05%) in middle stage and Herb-med of Bo-Qiheol were used(l0cases, 27.03%) in latter term. The most used Herb-med was Hoisu-san, Oyaksungi-san(22cases, 54.96%). 7. In l5cases which have Aqua-Acupuncture treatment, There were 3cases of Complete recovery, 5cases of Excellent, 4cases of Improvement, 2cases of Disimprovement, 1cases of Poor. 8cases(53.33%) were above Excellent grade, so it is more efficatious Than simple treatment without Aqua-Acupuncture(36.37%). 8. The improvement of Bladder, Small Intestine Meridian Muscle was 77.27%, Gallblader, Triple Energizer Meridian Muscle was 70% and Stomach, Large Intestine Meridian Muscle was 80%. Additional Aqua-Acupuncture treatment improved to be effective in Bladder, Small Intestine Meridian Muscle(77.78%), in Gallblader, Triple Energizer Meridian Muscle(75%), in Stomach, Large Intestine Meridian Muscle(100%).

건설산업에서의 안전 수준 향상 노력에도 불구하고, 건설산업은 타 산업에 비해 높은 사망자수를 보이고 있다. 이러한 높은 사고율은 건설산업의 안전관리 측면에서 효과적인 대책이 필요함을 명확히 의미한다. 기존의 연구에서 주장하듯, 사고의 발생 가능성이 높은 공종이나 기인물을 파악하고 이에 적합한 안전대책을 세우는 것이 중요하다. 다수의 추락관련 건설재해가 작업발판 및 안전통로에서 발생한다는 점을 고려해보면, 안전관리 측면에서 가시설물을 중점적으로 다루어야 할 것이다. 이를 위해 본 연구에서는, 작업발판 및 안전통로와 관련된 6개년 1663개의 사망사고를 공사규모, 공정률, 공종, 직종에 의해 분류하고, 각 사망재해가 발생한 사례들을 분석함으로써 보다 중점적으로 관리되어야할 요소를 추출하였다.

본 연구는 실험실 화학사고를 대상으로 각 연도별 사고현황, 사고유형, 사고원인 등의 화학물질사고 특성을 분석하였다. 그 결과 실험실에서 발생한 화학사고는 총 30건이었으며, 이중 25건이 학교 실험실에서 발생하였다. 실험실화학사고의 사고유형 중 유출 및 누출에 의한 사고가 가장 많이 발생했으며, 사고원인에 대해서는 작업자부주의로 인한 사고가 가장 많았던 것으로 나타났다. 실험실 사고예방과 연구활동 종사자의 보호를 위해서는 현장점검 강화, 유해화학물질 관리 감독 강화, 안전교육 강화 등 다각적인 정책적 노력이 필요할 것으로 사료된다.

The adjudication of Korean Maritime Safety Tribunal (KMST) was analyzed to collect basic data to identify the cause of the risk that did not appear in the current data provided by the fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) in stow net fishing vessel from 2015 to 2019. The personnel's carelessness was the most common in 29 out of 33 accidents (87.9%), followed by 25 cases (75.8%) of inadequacy of instructions, 24 cases (72.7%) of inadequacy of education on hazard factor, 20 cases (60.6%) of no personal protection equipment, 18 cases (54.5%) of poor guard, 17 cases (51.5%) of inadequacy of work method, 16 cases (48.5%) of absence of emergency stop button, 14 cases (42.4%) of work practice of poor safety precautions that affected more than 40% of all accidents as accident causes. These causes had a strong influence on each other, and the ratio of accident causes is high. With this relationship, accidents can be prevented or the severity of human injury can be reduced if types of accident process can be estimated with a scenario, and the key points before the accident in the scenario are switched to safe points.

Background: Household waste collectors (HWCs) are exposed to hazardous conditions. This study investigates the patterns of workplace injuries and work-related illnesses of HWCs. Methods: This study uses cases of workplace injuries and work-related illnesses of HWCs that occurred between 2010 and 2011. We analyzed 325 cases of injuries and 36 cases of illnesses according to the workers' age, length of employment, size of workplace, injured part of body, day and month of injury, type of accident, agency of accident, and collection process. Results: There were significant differences in the effect of workers' length of employment, injured part of body, type of accident, agency of accident, and collection process. Results show that most injuries occur in workers in their 50s and older. This study also shows that 51.4% of injuries occur at businesses with 49 employees or fewer. Injuries to waste collectors happen most often when workers are electrocuted after slipping on the ground. The second most prevalent form of injury is falling, which usually happens when workers hang from the rear of the truck during transportation or otherwise slip and fall from the truck. Work-related illnesses amongst waste collectors are mostly musculoskeletal conditions due to damaging postures. Conclusion: These findings will be instructive in devising policies and guidelines for preventing workplace injuries and work-related illnesses of HWCs.
