  • The construction workers might be at the risk of many occupational injuries and illnesses. To protect workers from various hazards, industrial health and hygiene systems were specified for the construction workers by law. It is important to know the actual health and safety(H&S) conditions by tasks and the characteristics of injuries and illnesses of construction workers. This study was designed to investigate the actual conditions of construction workers exposed to various harmful substances and work elements including evaluation of health status of each worker and general H&S system. Questionnaire was sent to 600 construction workers nationwide and totally 367 people responded to it having 61.67% of response rate. The common construction hazards were dust(29.6%), noise(19.3%), repetitive motions(12.0%), handling excessive heavy materials(11.2%) in order. The repetitive motions and handling heavy materials related to muscle disorders accounted for 23.2%. The accident and injury types were in order of overexertion, falling, overturning, dropping or flying, electric shock, collision, etc.

  • Today, with the development of modern civilization, the change of industrial structure and the increase of traffic volume and population make the number of maxillofacial injury patients also increase. Especially, the fracture possibilities of mandibular condyle have been increased because of mandibular position and shape. I experienced the case that mandibular condyle fracture caused by gun-shot injury(Bullet had been packed at the opposite condyle of input site) was treated by foreign body removal and condyle open reduction. I will represent that case with the journal review.

  • Repetition Strain Injury (RSI) is usually caused or aggravated by poor work processes and unsuitable working conditions - that involve repetitive or forceful movements or the maintenance of constrained or awkward postures. The condition is characterized by discomfort and persistent pain. There are three essential steps to eliminate or control hazards In workplace. Case and Demographic Characteristics for Work-related Injuries and illnesses Involving Days Away From Work, 2002. U.S' was examined. Causes of press operators' RSI were carpal tunnel syndrome(CTS), tendonitis, low back pain, and occupational stress. Recommendations for improvement of productivity are redesign of working conditions, exercise, prevent of RSI and avoiding stress.

  • The child restraint system is blown to be excellent to reduce child occupant injury in frontal collisions. The effects of the child restraint system are experimently investigated according to FMVSS 213. A sled simulator is utilized with varying restraint types such as 2point, 3point seat belts, forward-facing types and booster types of child restraint systems. The head and chest injuries for various cases are evaluated based on industrial standards. Also, the maximum displacements of the head and the knees are measured by film analysis. Using the results of the test, the effects of the child restraint system is discussed and reduction of child occupant injury is pursued.

  • Reactive oxygen species (ROS) induce a variety of cellular responses, such as proliferation, differentiation, senescence, and apoptosis. Intestinal epithelial cells are continuously exposed to ROS, and excessive generation of ROS severely damages cells via oxidative stress. Pro-inflammatory cytokines may lead to intestinal inflammation and damage by inducing excessive ROS generation. In this study, we showed that papiliocin, an antimicrobial peptide, significantly inhibited ROS production, without affecting cell viability. Moreover, TNF-α and IL-6 expression was decreased in the intestinal epithelial cells. The activity of papiliocin may significantly contribute to preserving the integrity of the intestinal mucosa against oxidative damage and inflammation-related disorders.

  • This study has found the socio-economic factors that affect occupational accidents and measured the influence quantitatively. We built the panel data of 4 countries (Japan, Germany, the U.S., and the U.K.) and the analysis model counted on the fixed effect model to reflect the countries' differences. The fatal occupational injury rates in the analyzed countries had a statistically significant relationship with the level of per capita GDP, the proportion of the construction industry, the rate of male workers, annual average working hours, the rate of workers in manufacturing and construction industries, etc. The annual average working hours have a positive correlation with the fatal occupational injury rate. To reduce occupational accidents effectively, we should be monitoring and researching various factors that can affect the occurrence of occupational accidents such as worker characteristics, changing industrial structure, and changes in working hours.

  • Objectives : Although dairy farming ranks as the industry with the highest injury incidence rate, the information on the injuries is limited in Gyeonggi Province. The purpose of this study was to investigate the occurrence of farm accidents and injuries. Methods : The occurrence of accidents among dairy farmers due to work-related injuries were investigated from 2,799 dairy farms of Seoul Dairy Cooperative. Among 171 total accidents, the number of accidents for human was 108. In this study, the 108 human accidents were investigated. Results : The results of this study were as follows; First, the injury rate in dairy farming was 1.60%. Second, the highest injury in dairy farm was occurred in the spring and at 6~8 p.m. Third, a variety of injuries occurred when doing the milking. Fourth, cow, machinery and falls were among the most common causes. Fifth, the most common injuries was fracture (52.8%) and the most common body part of injuries were torso (25.9%), legs (22.2%) and hand (18.5%). Sixth, 45% of the accidents indicated the lost work time from 4 weeks to 3 months. Recommendations: With the results, it is recommended that practical control methods to prevent accidents in dairy farming, for instance, wearing adequate personal protective equipment (PPE) or designing a moderate floor of works etc. be studied and developed.

  • Background: The Occupational Safety and Health Monitoring and Assessment Tool (OSH-MAT) is a practical instrument that is currently used in the German woodworking and metalworking industries to monitor safety conditions at workplaces. The 12-item scoring system has three subscales rating technical, organizational, and personnel-related conditions in a company. Each item has a rating value ranging from 1 to 9, with higher values indicating higher standard of safety conditions. Methods: The reliability of this instrument was evaluated in a cross-sectional survey among 128 companies and its validity among 30,514 companies. The inter-rater reliability of the instrument was examined independently and simultaneously by two well-trained safety engineers. Agreement between the double ratings was quantified by the intraclass correlation coefficient and absolute agreement of the rating values. The content validity of the OSH-MAT was evaluated by quantifying the association between OSH-MAT values and 5-year average injury rates by Poisson regression analysis adjusted for the size of the companies and industrial sectors. The construct validity of OSH-MAT was examined by principle component factor analysis. Results: Our analysis indicated good to very good inter-rater reliability (intraclass correlation coefficient = 0.64-0.74) of OSH-MAT values with an absolute agreement of between 72% and 81%. Factor analysis identified three component subscales that met exactly the structure theory of this instrument. The Poisson regression analysis demonstrated a statistically significant exposure-response relationship between OSH-MAT values and the 5-year average injury rates. Conclusion: These analyses indicate that OSH-MAT is a valid and reliable instrument that can be used effectively to monitor safety conditions at workplaces.

  • 본 연구의 목적은 비자살적자해(Non-Suicidal Self-Injury: NSSI)와 관련한 논문을 분석하여 연구적 성과와 한계점을 검토하고 향후 연구 과제를 제시하는 데 있다. 연구에 필요한 분석 대상 논문은 자해 관련 문헌 연구가 시작된 2010 년부터 현재까지 국내학술지를 중심으로 분류절차를 거쳐 수집하였다. 분류범주(일반적 특성, 연구대상, 연구변인, 프로그램 활용)에 따라 분석한 결과 첫째, 비자살적자해와 관련한 국내연구는 2017년(3편) 증가하기 시작한 이후로 2019년과 2022년을 거쳐 꾸준한 증가 양상을 보이고 있다. 둘째, 연구대상의 특성에 변화가 나타나기 시작했다. 이전의 선행 연구들이 자해를 경험한 청소년이 주 대상이었다면 초기성인기(대학생)까지 확대되었고 자해 중단경험을 가진 대상과 상담자, 부모로 연구대상이 다양해졌다. 셋째, 다양한 연구방법들이 나타나기 시작했다. 양적연구가 활발하던 2017년에 비하여 다양한 질적 연구방법들을(내러티브, 현상학, 근거이론, 메타분석, 사례연구) 적용한 연구가 진행되었다. 마지막으로 연구 결과에 대한 논의와 후속 연구를 위한 제언을 추가하였다.
