Purpose: This paper treats the improvement of the quality and reliability of military weapon systems based on the maintenance data. Methods: The proposed method of the data integration and refinement are used to obtain the component reliability information and to find the frequently failed components based on the Pareto analysis. Based on the reliability information and the number of failed component frequencies, the target components of quality improvement are determined and improved by multiple methods such as engineering changes, special meetings, additional training and revising maintenance manuals. Results: Based on the proposed process, we find some components which need to be improved in order to enhance the quality and reliability. Conclusion: A process is developed for improving the quality and reliability of weapon systems. This process will be adopted by various weapon systems to enhance the quality and reliability, as well as reduce military spending.

Object: The aim of this study is to suggest a list of priority chemicals for the Hazard & Risk Evaluation of Chemicals (HREC) controlled by the Industrial Safety and Health Act (ISHA). Method: Screening assessment was done for 642 chemicals whose exposure threshold limit values were set by the Ministry of Employment and Labor (MOEL). Hazard data were collected from Korea Occupational Safety & Health Agency (KOSHA) and/or other toxicity database. Exposure data were obtained from KOSHA internal database. The hazard and exposure scores of chemicals were listed by order of priority in accordance with GHS classification and exposure index data. Result: From the result of screening risk assessment for 642 chemicals, we extracted a list of 13 priority chemicals for HREC performed by the ISHA. A priority list of 27 chemicals which have carcinogen, mutagen and/or reproductive toxicity but not controlled by the ISHA was suggested for additional evaluation as "chemicals for special management".

본 연구의 목적은 디지털 환경에서의 과학기술분야 전문도서관 경쟁력 강화를 위한 경영전략수립에 있다. 정보통신기술의 발달로 인해 디지털도서관 정보서비스는 많이 발전했지만, 전문도서관의 경영환경(사서, 예산, 조직 등)은 더욱 어려워지고 있다. 이러한 현상의 원인 중 하나는 정보기술 만능주의에 가려진 경영전략의 부재에 있다. 본 연구에서는 이와 같은 문제점을 극복하기 위해 과학기술분야 전문도서관을 둘러싸고 있는 내 외적 환경변화를 알아보고, 경영전략수립 시 요구되는 단계 및 환경분석기법을 살펴보고자 한다. 최종적으로 과학기술분야 전문도서관의 미션과 비전을 제시하고, SWOT 분석기법으로 살펴본 전문도서관의 환경분석결과를 통해 구체적인 경영전략방안을 제시하고자 한다.

북한은 이미 오래 전부터 지하 공간을 군사적으로 활용하고 있으며, 현재는 비대칭 전력을 운용하기 위한 핵심거점으로 고도화하고 있다. 이에 따라, 특수작전팀은 지하작전 수행을 위한 싸우는 방법, 무기체계, 조직 구조 등이 필요하다. 이에 본고에서는 틸트로터형 드론, 첨단센서, 통신 중계기, 소형로봇 등을 융·복합한 지하작전용 무인체계 플랫폼과 특수작전팀이 이를 운용할 수 있는 체계를 제시하였다. 이를 통해, 특수작전팀은 생존성을 강화할 수 있고, 작전 효용성을 극대화할 수 있을 것이다. 향후, 특수전사령부에서 본고에서 제시한 지하작전 관련 아이디어를 집단지성을 통해 더욱 발전시킨다면 단기간 내에 한반도의 전장 환경에 최적화된 지하작전 교리, 무기체계, 조직·편성 등을 도출할 수 있을 것이다.

Background: Although spirometry results can be interpreted differently depending on the reference equation used, there are no established criteria for selecting reference equations as part of the special health examinations for Korean workers. Thus, it is essential to examine the current use of reference equations in Korea, quantify their impact on result interpretation, and propose reference equations suitable for Korean workers, while also considering the environmental conditions of special health examination facilities. Methods: The 213,640 results from the special health examination database were analyzed to identify changes in the ratio of measured values to reference values of lung capacity in Korean workers with changes in age or height, and changes in the agreement of interpretations with the reference equation used. Data from 238 organizations that participated in the 2018-2019 quality control assessment by the Korea Occupational Safety and Health Agency were used to identify the spirometer model and reference equations used in each special health examination facility. Results: Korean special health examination facilities used six reference equations, and the rate of normal or abnormal ventilatory diagnoses varied with the reference equation used. The prediction curve of the Global Lung Function Initiative 2012-Northeast Asian (GLI2012) equation most resembled that of the normal group, but the spirometry model most commonly used by examination facilities was not compliant with the GLI2012 equation. With a scaling factor of 0.95 applied to the Dr. Choi equation, the agreement with the GLI2012 equation was > 0.81 for men and women. Conclusions: We propose the GLI2012 equation as reference equation for spirometry in Korean workers. The GLI2012 equation exhibited the most suitable prediction curve against the normal lung function group. For devices that cannot use the GLI2012 equation, we recommend applying a scaling factor of 0.95 to the Dr. Choi equation.

Background: Some epidemiological studies have estimated exposure among flight attendants with and without breast cancer. However, it is difficult to find a quantitative evaluation of occupational exposure factors related to cancer development individually in the case of breast cancer in flight attendants. That is, most, if not all, epidemiological studies of breast cancer in flight attendants with quantitative exposure estimates have estimated exposure in the absence of individual flight history data. Case presentation: A 41-year-old woman visited the hospital due to a left breast mass after a regular check-up. Breast cancer was suspected on ultrasonography. Following core biopsy, she underwent various imaging modalities. She was diagnosed invasive ductal carcinoma of no special type (estrogen receptor positive in 90%, progesterone receptor positive in 3%, human epidermal growth factor receptor 2/neu equivocal) with histologic grade 3 and nuclear grade 3 in the left breast. Neoadjuvant chemotherapy was administered to reduce the tumor size before surgery. However, due to serious chemotherapy side effects, the patient opted for alternative and integrative therapies. She joined the airline in January, 1996. Out of all flights, international flights and night flights accounted for 94.9% and 26.2, respectively. Night flights were conducted at least four times per month. Moreover, based on the virtual computer program CARI-6M, the estimated dose of cosmic radiation exposure was 78.81 mSv. There were no other personal triggers or family history of breast cancer. Conclusions: This case report shows that the potentially causal relationship between occupational harmful factors and the incidence of breast cancer may become more pronounced when night shift workers who work continuously are exposed to cosmic ionizing radiation. Therefore, close attention and efforts are needed to adjust night shift work schedules and regulate cosmic ionizing radiation exposure.

This paper is about KTV special documentary "Baekdu to Halla, It's Peace Now" which looks back on the journey of President Moon Jae-in to the 3rd inter-Korean summit following former Presidents Kim Dae-jung and Roh Moo-hyun, following the 2018 inter-Korean summit held under the slogan of 'Peace and a New Future'. The documentary was produced in the form of a road documentary that looked back at the meaningful results of the summit meeting with the MC through related places and various people, narrated by singer Kang San-Ae. Based on this case, the difference between the development of road documentaries and general informational documentaries about the existing production process is identified, and the differences between the production format, production characteristics, and development method of road documentaries are described. I would like to present an example of how it can be desirable to set the format of the road documentary according to the production environment of broadcasting companies and planning factors.

This study examines the relationship between intrinsic motivation and individuals' performance in the Republic of Korea armed forces and explores whether job stress mediates the relationship between intrinsic motivation and individuals' performance. The research questions are: (1) Does intrinsic motivation influence individual performance in military organizations? (2) Does job stress impact individual performance? and (3) Does job stress mediate the relationship between intrinsic motivation and individual performance? The study utilizes data collected from a 350 soldiers survey in the Special Forces Brigade and Special Assault Commando Regiment of the Republic of Korea's Army. We use structural equation modeling (SEM) to explore the mediation role among intrinsic motivation, job stress, and individuals' performance. Research findings suggest that intrinsic motivation negatively impacts job stress. We also find that job stress has a positive effect on firearm skills. Moreover, the study reveals that the relationship between intrinsic motivation and firearm skills is partially mediated by job stress.
