Self-Inspection is being used in the workplace hazardous, dangerous machinery and equipment to build capacity for the voluntary safety risks due to use of machinery and prevention of industrial accidents that inspect facilities for safety issues, is to check. However, December 31, 2008 as part of Article 36 of the Occupational Safety and Health Act (safety inspection), the financial vanish as the self-test, Safety inspection program has been changed., In each individual workplace that creates its own standards and regulations to use the existing inspection system is in some cases. This study is located in the southeast industrial complex as a risk reducer manufacturer, machine-based target zones in S Corp owns most of the crane based on the results of the tests is to analyze the problem. Then check the results - to bring its measures and information you need to know for sure is to propose.

Recently, the impact on hearing induced by using of portable audio equipment have been actively studied. In general, Because they turn the volume up with loud background noise, they may expose to louder noise. In this study, we investigated the maximum noise level of 20 the domestic potable audio equipment and estimated the impact of the hearing induced by portable audio equipment in according to exposure time. As a result, the use of portable audio equipment is assumed to be more three hours when the level of more than 50 % of volume is most likely to affect the hearing.

Purpose: This study investigated the use of infection management and the frequency of emergency equipment sterilization by emergency rescue crews to provide basic guidelines and suggestions for infection control. Methods: A self-reported questionnaire was completed by 160 emergency medical technician rescue crews in J area from May 7 to May 22 in 2015. The questionnaire consisted of 95 items, including the general characteristics of the subjects (8 items), the use of emergency equipment (33 items), the frequency of facility sterilization (33 items), infection control (12 items), vaccination (4 items), and the use of personal protective equipment (5 items). Results: In all, 97.3% of respondents were aware of the "Guidelines of Infection management for Rescue Operators' and 90.9% received training on infection control. A total of 72.7% and 47.3% of rescue centers were equipped with disinfection facilities and laundry rooms, respectively. The average frequency of sterilization was $3.17{\pm}0.75$, which significantly differed for teams with more clinical experience (p=.050) and teams with three members (p=.030). The average score for individual protective equipment supplies was $1.95{\pm}0.66$. Conclusion: For proper infection management of emergency equipment, our results suggest that the number of crew members should be increased for each ambulance, protective equipment and rescue products should be supplied, and the number of facilities for sterilization and laundry at rescue centers should be doubled.

X선 발생장치의 정도관리는 의료기관의 설립형태에 따라 가장 큰 차이가 있으며, 장치의 보유율은 1차 의료기관에서 가장 많이 보유한 반면 정도관리에 대한 인식과 관리는 소홀하다 할 수 있다. 본 연구에서는 2010년 1월 4일부터 2010년 9월 3일까지 경북 지역을 4개의 권역으로 나누고, 각 시별로 4곳을 임으로 선정하였다. 전체 16곳에 있는 의원급 의료기관 중 10년 이상 된 X선 발생장치를 보유한 8곳과 10년 이하의 X선 발생장치를 보유한 8곳를 그 대상으로 하였으며, 정도관리의 필수 항목 5가지를 시험하였다. 접지 설비 확인시험에서는 10년 이상 된 X선 장치를 보유한 한 곳이 별도의 접지선을 구비하지 않았으며(6.25%), 외장 누설전류시험에서는 모두 적합 하였다. 조사선량 재현성 시험에서는 10년 이상 된 X선 발생장치를 보유한 4곳(25%)과 10년 이하의 X선 발생장치를 보유한 1(6.25%)곳이 부적합 하였다. 관전압의 정확도 시험에서는 10년 이상 된 X선 발생장치를 보유한 5곳(31.25%)과 10년 이하의 X선 장치를 보유한 2곳(12.5%)이 부적합 하였다. 관전류와 관전류량 시험에서는 10년 이상 된 X선 장치를 보유한 3곳(18.75%)과 10년 이하의 X선 장치를 보유한 1곳(6.25%)이 부적합 하였다. 본 연구 결과 10년 이하의 X선 발생장치를 보유한 의원급 의료기관 보다 10년 이상 된 의원급 의료기관의 X선 발생장치의 정도 관리 실태는 심각한 수준 이였다. 검사 결과를 바탕으로 행정적, 기술적인 조치들이 신속하게 이루어져야 할 것이다. 또한 의원급의 사업주나 장치 담당자들의 의식 전환이 필요 하며 그러기 위해서는 오래된 장비이거나 자주 사용하지 않는 장비일수록 정기검사주기를 1~2년 단위로 개정하여야 하고, 정기적인 정도 관리 교육 프로그램을 실시하여야 할 것으로 사료된다.

Sport has no age limit and can be done anywhere and in any condition with minimal equipment. The existence of sports spaces in all parts of the world is considered a citizen's right. One of the activities carried out in this field is installing sports equipment and structures in parks and encouraging citizens to use this equipment for physical health with the least cost and facilities. Installing sports structures in open spaces such as parks is a practical step for developing citizens' sports. Although using devices in parks is acceptable, it is more critical to meet scientific and technical standards. The components of these structures must have high strength and endurance against changes in environmental conditions such as humidity, temperature difference, and corrosion. Among the various causes of material degradation, corrosion has always been one of several fundamental causes of metal equipment failure. Sports structures in open spaces are not safe from corrosion. Uniform corrosion is the most common type of corrosion. This corrosion usually occurs uniformly through a chemical or electrochemical reaction across the surface exposed to the corrosive environment. Rust and corrosion of outdoor sports structures are examples of this corrosion. For this reason, in this research, with the green synthesis of silica nanoparticles and its application in outdoor sports structures, the life span of these structures can be increased for the use of physical exercises as well as their quality.
