Background: According to the previous studies, the work-related accident rate decreased in Korea after the introduction of occupational health and safety management system (OHSMS), but there were several disasters in Korea such as subway worker's death at Guui station in 2016 and the Taean thermal power plant accident in 2018, which escalated the social demand for safety. In 2018, OHSMS became an international standard, as ISO45001 was announced. Methods: A survey was conducted to research the implementation status of OHSMS and changes in people's perception, and the results were compared with those of a past survey. Results: Enhanced social demand and various stakeholders' (not only buyer) needs, and social responsibility are perceived as the motivation for the introduction of OHSMS rather than legal compliance or customer demand. In the questionnaire about problems with the implementation of OHSMS, the factors with higher response rate in 2018 than 2004 were "excessive cost" and "complicated documentation management." In the questionnaire about how to promote OHSMS in organizations, most people answered "reduction of workers' compensation insurance rate" in 2004, but most people answered "exemption from health and safety supervision" in 2018. Conclusion: For the effective implementation of ISO45001, emphasis is placed on social demand, training to recognize health and safety as a part of management, and the reduction of certification and consulting costs to promote the introduction of OHSMS. Incentives such as insurance premium cuts and exemptions from health and safety supervision are needed.

인류는 과학기술의 발전과 함께 의학기술도 눈부신 발전을 거듭해왔다. 그러나 과거에도 난치성 질환은 여전히 존재하였듯이 지금도 난치성 질환이 존재하는데, 그 중 턱관절장애가 있다. 현재 의료선진국이라 불리는 대한민국 의료진들의 진단은 환자의 발언, 의사의 청음진단과 자를 이용한 진단, X-ray 촬영 진단 방식을 고수하며 시대에 뒤떨어지고 있다. 그렇기 때문에 환자의 정확한 증상 여부, 의사 본인의 진단 실력과 경력이 중요하고, 증상의 경중에 따른 진단 횟수의 증가와 이로 인해 발생하는 의료비용은 막대하다. 본 연구에서는 이를 해결하기 위해 저작운동(최대폐구)시 교근에서 발생되는 근전도 신호를 %MVC를 통해 정량화하였다. 정량화된 근전도는 Cortex로 비교, 평가하여 턱관절 상태 평가 기준 지표를 확립할 것이다.

본 논문은 시뮬레이션 기반으로 메타 모델을 이용하여 LEEFI형 착화장치의 설계 신뢰도를 추정하는 방법과 설계 신뢰도를 추정한 결과를 나타내었다. LEEFI형 착화장치에서 비행편 속도는 화약 기폭에 중대한 영향을 미친다. 복잡한 물리적 현상으로 비행편의 속도가 발생하기 때문에 문헌에 공개된 역학적 모델을 이용하여 비행편 속도를 평가하는 데 많은 연산 시간이 필요하다. 또한 높은 신뢰도를 가지는 착화기는 요구되는 신뢰수준이 증가할수록 신뢰도 평가에 연산 비용이 증가한다. 따라서 설계 신뢰도 추정시 연산 효율성을 증가시키기 위하여 시간에 따른 비행편 속도에 대한 메타모델을 구축하였다. 구축한 메타모델을 이용하여 설계 변수의 다양한 분포 및 시그마 수준에 따른 설계 신뢰도를 추정한 결과를 나타내었다. 그리고 제안하는 추정 방법에 대한 연산 효율성과 정확성을 분석하였다.

Background: Painters in the automotive sector are routinely exposed to volatile organic solvents, and the levels vary depending on the occupational health and safety controls enforced at the companies. This study investigates the levels of exposure to organic vapors and the existence of controls in the formal economy sector in southern Colombia. Methods: This is an exploratory study of an observational and descriptive character. An analysis of solvents is conducted via the personal sampling of painters and the analysis of samples using the National Institute for Occupational Safety and Health 1501 method. The amount of solvents analyzed varied according to the budget allocated by the companies. The person in charge of the occupational safety and health management system was interviewed to learn about the exposure controls implemented at the companies. Results: A medium exposure risk for toluene was found in one company. Another presented medium risk for carbon tetrachloride, xylene, ethylbenzene, and n-butanol. The others showed low risk of exposure and that the controls implemented were not sufficient or efficient. Conclusion: These results shed light on the working conditions of these tradespeople. The permissible limits established by Colombian regulations for the evaluated chemical contaminants were not exceeded. However, there were contaminants that exceeded the limits of action. The analysis of findings made it possible to propose improvements in occupational safety and health management systems to allow the optimization of working conditions for painters, prevent the occurrence of occupational diseases, and reduce costs to the country's health system.

Objectives: Chronic diseases (CDs) continue to increase due to advances in medicine and increase in lifespan, affecting quality of life and resulting in economic loss through treatment costs. This study addressed the perception characteristics of the effectiveness of Korean medicine (KM) based on the existence of a CD to determine the national preference for KM treatment. Methods: Using data from the 2017 National Survey of KM Usage, we evaluated the perception on treatment effect of 16 diseases by dividing them into the CD group and the non-CD group. Response reliability was verified by applying the chi-square test (χ2-test) analysis method of the Statistical Package for the Social Sciences (SPSS) statistical program. Results: The analysis of the perception on effectiveness of KM for patients with CD (n = 1,050, 21.0%) and for patients with non-CD (n = 3,950, 79.0%) showed an overall similar trend for all the 16 diseases. The response rates of having some treatment effect were high for nine diseases namely, disc-related disease (CD: 70.7%, non-CD: 73.1%), osteoarthritis (CD: 72.3%, non-CD: 72.4%), frozen shoulder and shoulder pain (CD: 79.6%, non-CD: 81.4%), back pain (CD: 84.6%, non-CD: 85.0%), sprain (CD: 84.8%, non-CD: 84.1%), facial nerve paralysis (CD: 73.5%, non-CD: 71.7%), stroke (CD: 66.2%, non-CD: 62.8%), digestive disease (CD: 53.3%, non-CD: 50.0%), and common cold and rhinitis (CD: 44.7%, non-CD: 44.8%). Conclusion: The present results found that there was little difference in the perception on effectiveness of KM for each of the 16 diseases in patients with CD and non-CD, however, 70% or more of the respondents recognized some treatment effect on musculoskeletal disorders, regardless of the existence of CD. Preferential political support for KM treatment of chronic musculoskeletal disorders is recommended.

The fourth industrial revolution based on information and communication technology (ICT) becomes the center of society, and the overall industrial structure is also changing significantly. ICT refers to the hardware of information devices and the software technologies required for the operation and information management of these devices, and any means of collecting, producing, processing, preserving, communicating and utilizing them. ICT is integrated into industries and services or combined with new technologies in various fields such as robotics and nanotechnology to connect all products and services to the network. The development of ICT, which continuously creates new products and services, has spread to all sectors of the industry, affecting not only daily life but also the livestock sector recently. In agriculture, ICT technology can reduce production costs by efficiently managing labor and energy because it can improve quality and yield based on data on environmental and growth information such as temperature, humidity, light and soil. In particular, smart livestock is considered suitable for achieving livestock management goals because it can reduce labor force and improve productivity by remotely and automatically managing accurate information necessary for raising and breeding livestock with ICT devices. The purpose of this study is to propose the need for ICT technology by comparing farm productivity before and after ICT is introduced. The method of the study is to compare the productivity before and after the introduction of ICT in Korean beef farms, pig farms, and poultry farms. The effectiveness of the study proved the excellence of ICT technology through the production results before ICT introduction and the productivity improvement case of livestock farms that efficiently operated manpower management and reduced labor force after ICT introduction. The conclusion of this paper is to present the need for smart livestock through ICT adoption through case study results.

본 연구는 국민연금의 지분투자가 기업의 보수적 회계처리 의사결정에 미치는 영향을 규명하기 위해 2011년부터 2018년까지 국내 유가증권시장에 상장된 10,117개 기업-연도 표본을 대상으로 실증분석을 실시하였다. 분석 결과, 국민연금이 주요주주로서 5%이상의 지분을 보유하고 있는 기업은 그렇지 않은 기업에 비해 보수적 회계처리 경향이 감소하는 것으로 나타났다. 이와 같은 국민연금 주요주주 투자와 보수적 회계처리간 음(-)의 관련성은 주요주주로서 존재하는 국민연금의 투자기간을 단기(1년 미만)와 장기(3년 이상)로 구분하여 분석한 경우에도 일관되게 나타났다. 국내 최대 기관투자자인 국민연금은 기업의 재무상태와 영업성과, 미래 현금흐름에 대한 분석능력이 뛰어나고, 최근에 스튜어드십 코드 도입으로 국민연금의 적극적 주주활동 가능성이 증가하는 등 기업에 대해 유의미한 경영권 견제활동을 수행할 수 있을 것으로 기대되는 바, 자본시장에서 국민연금의 모니터링 기능이 효과적으로 작동하여 대리인 비용이 감소하고 기업의 보수적 회계처리에 대한 투자자들의 요구가 줄어들었기에 본 연구와 같은 실증분석 결과가 나타난 것으로 판단된다.
