In order to study the occurrence of symptoms of musculoskeletal disorders of radio-technologists employed at metropolitan general hospitals and the factors that influence such occurrence, standardized questionnaire by NIOSH that was modified and supplemented to be suitable for conditions in Korea was used. Answers collected from 143 radio-technologists in two weeks from June 13, 2007 were analyzed and the results are as follows. Factor that influence symptoms of musculoskeletal disorders by area were analyzed through multiple logistic regression analysis and the results found that in the neck area, risk increased as the burdening work category 2(Korea ministry of labor)(OR=3.94) and burdening work category 9(Korea ministry of labor)(OR=4.72) increased. In the shoulder region, risk increased as burdening work category 2(Korea ministry of labor)(OR=5.36), burdening work category 7(Korea ministry of labor)(OR=3.90), and burdening work category 9 (Korea ministry of labor)(OR=5.76) increased. In the arm/hand/wrist regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=6.91), and burdening work category 9 (Korea ministry of labor)(OR=3.76) increased. In the lower back region, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.06), and burdening work category 8 (Korea ministry of labor)(OR=8.14) increased. In the leg/knees/foot regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.63), and burdening work category 9 (Korea ministry of labor)(OR=2.96) increased. Conclusively, in factors that influence musculoskeletal disorder symptoms in radio-technologists, influence of subjective health conditions, total work experience, experience in current division, and burdening work category 2, 7, 8, and 9 (Korea ministry of labor) were most significant. Therefore, for preventive management, in addition to ergonomic and educational intervention for correcting improper posture during work, efforts for break time adjustment and stress reduction is needed, and encouragement and support for regular exercise is needed.

The purpose of this study was to understand the dental hygienist's perception of dental materials and to understand the safety status of harmful chemicals. The study was conducted from January to February 2015 for 250 dental hygienists working in Gwangju Metropolitan City. as a result, the degree of recognition of MSDS for dental materials was higher with age (P <0.05) and higher in dental hygienist (P <0.001) working at dental hospital. (P <0.001), and the factors affecting the perception of first aid treatment were positively correlated with experience of hazard education (P <0.001). Therefore, by understanding the MSDS awareness of dental materials by dental hygienists and the safety situation in the handling of hazardous chemical substances, we provide basic data for establishing proper recognition of safety in the handling of harmful chemical substances and developing educational programs to prevent accidents.

Purpose: This study aimed to systematically review literature and conduct a meta-analysis to comprehensively identify and evaluate the effects of workplace risk assessment-based ergonomic intervention on work-related muscular-skeletal disorders in workers. Methods: We searched the Ovid-Medline, EMBASE, and Cochrane library and up to 2018 using search terms such as muscular-skeletal, disorder, impairment, work-related muscular-skeletal disorders, ergonomic, intervention, management with no language limitations; screened reference lists; and contacted experts in the field. Results: We identified 545 references and included 13 randomized controlled tests (3,368 workers). We judged nine studies to have a low risk of bias, while the other four studies have a high risk of bias. Conclusion: Ergonomic intervention based on risk assessment in the workplace did not significantly differ in terms of the intensity of pain or duration of workers in the workplace, but low-quality evidence decreased the frequency of musculoskeletal disorder pain in three to six months moderate-quality evidence and in six to nine months low-quality evidence. Besides, low-quality evidence to reduce discomfort and moderate-quality evidence to improve worker posture. Therefore, ergonomic intervention based on the assessment of risk factors in the workplace should be applied to reduce pain frequency and discomfort and improve workers posture among musculoskeletal disorders.

An annual average of more than 100 casualties occur on construction sites designated by the occupational safety and health law despite the safety assessment regulations from Korea Occupational Safety & Health Agency. Even if those sites involve more harmful or hazardous work than other sites, the result creates doubt regarding the effectiveness of the safety assessment regulations. The safety of construction sites is difficult to maintain continuously and instantly because ofthe variability in the construction industry despite inspecting workers, equipment, and facilities by managers. Many discussions on how to utilize BIM have been made to improve the productivity of construction projects, and BIM-based modeling and simulation would bring many benefits to safety. This study examined the hindrance factors of field utilization of the safety assessment regulations through a research literature survey, disaster situation analysis and questionnaire, and suggests the necessity of the application of BIM that enhances the effectiveness of safety assessment regulations by identifying the relationship between the hindrance factors and the function of BIM.

The purpose of this study is to identify the harmful factors of teacher's job stress and occupational-related musculoskeletal diseases, and to investigate according to job types to seek solutions and improvement measures for removing harmful factors. A total of 168 elementary and high school teachers in Seoul were surveyed. As a result, the average RULA score of the teacher was 4.2 points, and the average RULA score of the teacher who did not complain of musculoskeletal diseases was 4.3 points. In addition, the average job stress score of the teacher was 58.9 points, and the stress score by factor was in the order of student guidance, work burden, loss of authority, organizational structure and curriculum, treatment and welfare, human relations. As a result of analyzing the teacher's RULA score and job stress, it was possible to derive a correlation between musculoskeletal disorders and job stress caused by occupation.

It may occur health hazards or death by suffocation or acute poisoning in case of oxygen deficiency in ambient or exposure to harmful gas. As a part of accident prevention, we studied the change of activity and lethal dose by changing the concentration of several hazardous gas with inhalation exposure chamber and laboratory animals. We investigated the lethality and motility change during either the 4 hrs whole body exposure to oxygen, nitrogen, toluene, $H_2S$, CO and 48 recovery. As results, it is estimated that 5% oxygen concentration as lethal concentration and 5.5% as $LC_{50}$ (rat, 4 hrs) with statistics for dose-response. The results of lethality in oxygen deficient condition (approximately 6%), the lethalities were 40%, 20% with 20 ppm $H_2S$, 600 ppm CO respectively, and was not increased the lethality with 8% CO. Thus, it was confirmed that the $H_2S$, CO had influence to lethal dose, while toluene had low fluence.

The aim of this study was to develop a reliable dietary questionnaire to assess human exposure to food-borne hazards. Eleven food-borne hazards were chosen as a priority control list through a literature review and advisory committees. The 11 food-borne hazards were phthalate, aflatoxin, bisphenol A, polycyclic aromatic hydrocarbons, dioxin, polychlorinated biphenyls, mercury, lead, cadmium, arsenic, and acrylamide. The characteristics, exposure level, and paths of these hazards were reviewed, and questionnaire items were identified to assess human exposure from the literature. A questionnaire was developed for each selected food based on its characteristics. Based on the items in the individual questionnaires, a comprehensive questionnaire, which contained demographic characteristics, job information, socioeconomic factors, health related lifestyles, and dietary behaviors, was developed. A 99-item food frequency questionnaire (FFQ) to assess food-borne hazard exposure was also developed. The FFQ included frequency of food intake during the previous year, container type for purchasing and storing food, and cooking method. The questionnaire developed in this study could be applied to assess dietary factors during an exposure assessment of food-borne hazards in a large population. A validation study for the questionnaire is needed before applying it to surveys.

국내외의 근골격계질환에 대한 현황과 자료를 검토하였다. 국내의 자료는 지난 수년간 대학 연구소에서 수행한 유해요인조사 및 예방사업 과정에서 수집된 자료들이다. 제조업에서 서비스업에 이르는 다양한 업종의 현황을 비교하였다. 외국의 자료와 비교할 때 가장 큰 특징은 국내의 근골격계질환 자료는 발생건수에서도 실제 생산형장에서의 현황보다 축소되어져 있지만, 전체 산업재해나 직업병에서의 비율로 볼 때도 매년 그 발생 비율이 불안정하게 등락함으로서 아직도 국내의 근골격계질환의 발생비율은 여전히 정확한 현황 파악이 되지 못하고 있는 것으로 평가된다. 국내외 자료를 비교 분석한 결과 국내의 근골격계질환 현황은 외국의 평균치와 비교하여 10배 이상 저평가 되어 있는 것으로 분석된다. 또한 업종별로 평균 유병율은 적게는 5%에서 많게는 10% 이상에 이르는 것으로 추정되어진다.
