Public institutions have a responsibility to ensure the safety of their employees and the public. One way to do this is to implement a systematic safety inspection system based on risk assessments and continuous improvements. This study developed a systematic safety inspection system for public institutions that are ordered construction projects. The proposed system in this study consists of a three-step process: (1) developing safety grade evaluation tables, (2) preparing and conducting safety inspections, and (3) evaluating and improving safety management grades. The first step is to develop safety grade evaluation tables by analysis and diagnosis of the construction site's work type, disaster statistics, and related laws. The second step is to conduct safety inspections using the developed evaluation tables. The third step is to determine the safety management grade based on the results of the safety inspection, and to improve risk factors found during the safety evaluation. The proposed system was implemented in highway construction projects carried out by public institutions. The results showed that the proposed system has two major effects: (1) reducing accident-related deaths and injuries, (2) improving safety management levels by continuous evaluation and improvement. The proposed system can be utilized in construction projects ordered by public institutions to improve the level of occupational safety and health.

본 연구는 Siphon Breaker Simulation Program(SBSP)을 이용하여 소규모 사이펀 차단기 실험장치를 설계 및 제작하고, 실험 수행 후 그 결과를 이용하여 다양한 규모의 사이펀 차단기에 대한 SBSP의 적용 가능성을 평가하기 위해 진행되었다. 실험장치 설계를 위하여 C factor와 Chisholm B 계수, Undershooting Height(UH)에 대한 시뮬레이션 결과값을 SBSP로 도출하였다. 실험장치의 중요파트는 upper tank, lower tank, downcomer, Siphon Breaker Line(SBL) 등이며, upper tank는 넓이 $0.09-m^2$, 높이 0.65-m의 크기로 제작되었고, downcomer 높이는 1.6-m로 제작되었다. 실험결과 분석을 위하여 압력계, 차압계, 전자저울이 사용되어 압력과 차압, 유량에 대한 정보를 도출하였다. 실험에서 사용된 실험변수는 Loss Of Coolant Accident(LOCA) 크기와 SBL 크기이며, LOCA는 30-mm와 38-mm에 대해서, SBL은 6/16-inch와 8/16-inch에 대해서 실험이 진행되었다. 실험의 결과로 유량과 압력, 그리고 UH를 도출하였으며, 실험결과를 SBSP의 시뮬레이션 결과와 비교, 분석하였다. UH 측면에서 SBSP가 수조의 총 높이 대비 2.5 %의 오차로 실험결과를 잘 예측하는 것을 관찰하였다. 그러므로 SBSP를 이용한 다양한 규모의 사이펀 차단기 설계가 가능한 것을 확인하였다.

손상 사고 중독과 관련해 환자의 의료비 증가는 국가건강보장체계의 지속가능성을 제고하기 위한 중대한 과제이며, 제도의 개선이나 건강보험의 관리 운영 효율화를 통한 의료비 증가를 억제할 필요가 있다. 따라서 손상 발생과 사망률이 높은 우리나라에서 손상 문제를 사회적으로 강조하기 위해서는 손상의 사회경제적 비용을 추계하는 것이 필요하다. 본 연구는 2008년도 한국의료패널 조사 중 외래 손상 사고 중독 환자를 대상으로 이용실태와 의료비지출을 전반적으로 파악하여, 손상으로 외래 서비스 이용 시 환자의 직접비용과 생산차질 등으로 인한 생산손실비용을 추계하였고, 궁극적으로 손상의 사회경제적 손상 비용을 추계하였다.

본 연구 목적은 산업재해로 인한 사망자와 부상자가 너무 많다는 비판이 오랫동안 지속되어 온 부분과 근로자의 죽음은 한사람의 죽음뿐만 아니라 그와 연결된 많은 사람들과 사회 전체에 악영향을 미친다는 문제임은 분명히 인식하고 엄중한 '중대재해처벌법'의 필요성은 공감을 하고 있다. 그러나 현행 중대재해처벌법은 노사 양측에서 애매하다는 논란의 여지가 있어 환영받지 못하고 있는 점과 안전보건 확보 의무를 위반한 경영책임자는 처벌과 입법 내용이 추상적이며 처벌 수위가 지나치다는점을 제언한다. 그리고 경영책임자의 해석과 중대산업재해의 애매한 부분으로 대부분의 기업들이 법률해석과 자문을 받고자 대형 로펌을 기용하므로 로펌만 배불리는 양상을 만들고, 기업은 CEO를 보호하기 위해 투입하는 비용은 정작 안전사고 예방비용으로 들어가야 하므로 모호성을 갖고 있는 지금의 시행령은 개정되어야 할 필요성이 있다는 것을 제언한다.

The incidence of spinal cord injury increase due to traffic accident, industrial accident and leisure sports. Spinal cord injury damages motor and sensory function below the injury level, also affects autonomic functions associated with voiding and defecation. Sexual dysfunction and psychosocial, vocational maladaptations are also some of the unwanted consequences of injury. The purpose of this study is look for means to prevent and to manage complications in spinal cord injury through investigation and analysis. The subjects of this study in spinal cord injured patients were admitted to the department of physical therapy, Kwangju christian Hospital, Nam Kwang Hospital, Chun Nam university Hospital and Cho Sun university Hospital, from April, 1, 1995 to March, 31, 1996. The results are as follows: 1. The subjects comprised 96 cases of spinal cord injury, ranging from 17 to 85(mean-40.8 yrs) and included 72 males and 24 females. Among these patients, 58 were cervical injury, 20 were thoracic injury and 18 were lumbar injury. 2. As for a major causative of spinal cord injury were traffic accident(59.4%), fall down (27.1 %), and motocycle(4.2%).. 3. The bladder control were taken by indwelling cathetar(41.7%), Crede maneuver(37.5%) and self voiding(16.7%). The bowel control were taken by all aid(61.5%), assitance(32.3%) and self defecation(6.2%). 4. Possible of sexual function were 35 cases (47.9%). 5. The device of transfer used wheel chair(69.8%) and bed(16.7%). 6. The patients with higher cord lesion got more serious pain than lower cord lesion. Also the patients with higher cord lesion got a serious spasticity. 7. The incidence of decubitus ulcer among 96 patients were in case 46(47.9%). The largest group of the pressure sore sites were sacral portion(82.0%), less than 1 month of onset occured a large numbers(50%). Incidence of pressure sore by spasticity occured many patients in case of mild or moderate. Incidence of pressure sore by pain occured many patients in case of severe pain.

Objectives: The mandible and other parts of the maxillofacial region suffer significant morbid injuries following road traffic accidents. Our study gives epidemiological description of mandibular fractures in Ghana and also evaluates the relevance of closed reduction and indirect fixation for managing mandibular fractures in low-resource health facilities in low-income countries like Ghana. Patients and Methods: This is a retrospective study involving 268 patients who reported to the Department of Oral and Maxillofacial Surgery of the Sunyani Regional Hospital with mandibular fractures from January 2010 to December 2019. Patient medical records were assessed for information on age, sex, fracture etiology, anatomic location of fracture, time of day of road traffic accident, and other associated injuries. Results: A total of 268 patients were included in this study (males, 216 [80.6%]; females, 52 [19.4%]). Motor vehicular accident (MVA) was the leading cause of mandibular fractures (202 injuries, 75.4%). Other etiologies included assault (39, 14.6%), gunshot (13, 4.9%), falls (12, 4.5%), and industrial accidents (2, 0.7%). Of the 161 male cases caused by MVA, 121 (75.2%) occurred at night and in the evening while the remaining 40 (24.8%) occurred in the morning and afternoon. Among all managed 222 patients, 212 (79.1%) were treated with closed reduction and indirect fixation technique while 10 (3.7%) were treated with open reduction and direct fixation. Conclusion: Closed reduction with indirect fixation could successfully be used to manage mandibular fractures in low resourced health facilities, especially in low-income countries. The poor lightening system on roads in Ghana is a major contributory factor to motor vehicular accidents.

This study examines the relationship between safety factors and health management systems based on accident statistics in the construction industry stipulated in the Serious Disaster Punishment Act. To determine the level of safety achieved by companies through their health management system, the top 1000 construction firms in the country were surveyed online. Four hundred sixty companies responded to the survey by providing their statistics on major accidents (mortality, accidental mortality, and injury rates). Statistical tests showed that companies with a team dedicated to the oversight of safety and health management had fewer accidents than those without one. Factor and regression analyses revealed that three factors affected the mortality and accident rates: safety and health plan, safety and health professionals, and safety and health activities. Moreover, two factors significantly influenced the injury rate: safety management supported by a cooperative company and implementation of on-site safety and health activities. The findings of this study can be used as a fundamental reference for further research and consultation on the formulation of safety and health management systems for construction companies.

화학공장에서 발생하는 사고의 발생원인은 다양하지만, 전 세계적으로 발생되는 산업재해의 96%는 근로자의 불안전행동에 의해 발생된다. 국제노동기구(International Labour Organization, ILO)에서는 근로자의 불안전행동에 의한 사고의 위험성을 경고하기 위하여 산업현장에서 다발적으로 발생하는 근로자의 불안전 행동을 20개의 요소로 구분하여 발표한 바 있으며, 산업재해 예방을 위해서는 근로자의 불안전행동을 제어하여야 한다고 강조하고 있다. 본 연구에서는 근로자의 불안전행동을 관리할 수 있는 방법을 알아보기 위하여 국내사업장의 사고조사 이력 정보를 토대로 현장에서 다발적으로 발생하는 주요 불안전행동 유형을 분석 하였다. 주요 불안전행동 분석 결과를 기반으로 Swiss Cheese Model을 이용하여 불안전 행동을 유발하는 근본원인을 분석하였으며, 각 근본원인별 관리방법을 제안하였다.
