This study was conducted to compare and analyze occupational stress and satisfaction levels of the nurses in two different units to provide data for effective nursing resource management. Survey was conducted in four hospitals in June 2019 and data was obtained from 62 nurses in comprehensive nursing service units (CNSU) and 62 nurses in general units (GU). CNSU nurses had higher level of job satisfaction than GU nurses. Contributing factors included pay, professional status, administration, autonomy, task requirements, and interaction. Job stress level was not significantly different between groups. GU nurses had higher stress levels from nursing practice, conflict with doctors, and patients and caregivers, while CNSU nurses had higher stress levels in working condition. Negative correlation was found between job satisfaction and stress in GU nurses, whereas not in CNSU nurses. Clear definition of task, smaller work load, appropriate reward, and educational support is suggested to enhance job satisfaction.

Purpose: The purpose of this study was to develop a comprehensive health promotion program for North Korean young adult defectors in South Korea. Methods: The comprehensive health promotion program consisted of nutrition, mental healthcare, physical activity and sexual behavior was developed on the basis of need assessment results. For the evaluation of the program, 70 North Korean young adults who were attending two alternative schools for North Korean defectors were recruited. The program had taken place once a week for 13 or 19 weeks. Effectiveness of the health promotion program was evaluated using anthropometric measurement, 3-day food records and a questionnaires that comprised the Hospital Anxiety and Depression Scale (HADS), the Short Form with 36 questions (SF-36) and health behaviors. The surveys were proceeded at the beginning and after the program. Results: After health promotion program, participants' height was significantly increased (p=0.004) and body fat mass (0=0.004) and percentage of body fat mass (p=0.003) were significantly decreased. The number of subjects who ate breakfast alone was decreased whereas the number of subjects who ate breakfast with friends was increased (p<0.001). There were no significant changes in dietary intakes, mental health status and quality of life. North Korean young adult defectors' willingness to participate and interests in the health promotion program were high, however the practice rate was low. Conclusion: The health promotion program could induce interests and willingness to participate, but bring about limited effects on the health behaviors. These results imply that a health promotion program for North Korean young adult defectors should have a long-term strategy as well as short-term plan. Furthermore, it should be based on their health problems, health related behaviors, academic performance and daily life matters.

Although the Korean government (Ministry of Ocean and Fisheries) and related organizations are enforcing many policies to improve the marine safety of vessels with weak safety management, the effectiveness of each policy is deficient due to the lack of a risk assessment method for ship safety management. Most previous studies in Korea of the risk assessment of ships only dealt with fragmentary risks of individual marine accident risks, so a new assessment method for comprehensive marine accident risk is needed. Examples of comprehensive risk assessments for ship safety management are the selection method for inspection targets by the Port State Control and the Norwegian Maritime Authority. In this study, indicators for the comprehensive risk assessment of ship safety management were developed for and applied to coastal/offshore fishing vessels that occupy a high proportion of the registrations and marine accidents in Korea. As a result, the risk of each ship was confirmed quantitatively, and a ranking of the weakness factors for ship safety management was identified.

This study aims at conducting a quantitative assessment of potential economic effects of the Regional Comprehensive Economic Partnership (RCEP) consisting of 10 Member States of the ASEAN, Australia, China, India, Japan, Korea and New Zealand using a multi-region, multi-sector CGE model. Three different policy scenarios are carried out based on baseline scenarios: China-Japan-Korea FTA (Scenario 1); ASEAN+3 FTA (Scenario 2); and the RCEP (Scenario 3). The impacts of three scenarios are described in terms of real GDP, Equivalent Variation as a measure of welfare, export and import volumes, trade balance, and terms of trade. This study finds that the RCEP is to lead to an increase in real GDP of all members of the RCEP, with Korea as a winner with a highest additional economic growth of 2.43 percent, which implies that Korea is in a better position to play a leading role in promoting the RCEP.

Purpose: This study was conducted to collect and analyze real world data to evaluate the effectiveness and safety of comprehensive traditional Korean Medicine treatment on quality of life, anorexia and cachexia of cancer patients. Methods: We analyzed medical records of 62 cancer patients admitted to O-I Dang Korean Medicine Hospital from February 2018 to February 2019. The primary outcome was a change score in the Anorexia/Cachexia Subscale of Functional Assessment of Anorexia/Cachexia Therapy (FAACT). The secondary outcomes were Functional Assessment of Cancer Therapy-General (FACT-G), Trial Outcome Index(TOI) of FAACT, 11 point Pain Intensity Numeric Rating Score (11 PI-NRS) and Patient Global Impression of Change (PGIC) and adverse event. Results: Cachexia and quality of life in cancer patients assessed by FAACT, increased by $5.59{\pm}14.83$ (p=0.004) after treatment. PI-NRS was reduced by $2.10{\pm}1.81$ (p<0.001) and TOI and FACT-G total scores were increased by $5.17{\pm}11.70$ (p=0.001) and $3.59{\pm}10.94$ (p=0.012), respectively. These results were also clinically meaningful assessed via minimal clinically important difference (MCID). There was no severe adverse event. Conclusion: These findings suggest that comprehensive traditional Korean Medicine treatment might be effective and safe strategy for improving quality of life, anorexia, cachexia and pain of cancer patients. Further advanced studies with controlled group and more participants with rigorous design are needed to ensure these findings.

Civil aviation cybersecurity challenges are global in nature and must be addressed using global best practices and the combined efforts of all stakeholders. This requires the development of comprehensive international strategies and detailed plans for their implementation, with appropriate resources. It is important to build such strategies on a common methodology that can be applied to civil aviation and other interrelated critical infrastructure sectors. The goal of the study was to determine the methodological basis for developing an international civil aviation cybersecurity strategy, taking into account existing experience in strategic planning at the level of international specialized organizations. The research was conducted using general scientific and theoretical research methods: observation, description, formalization, analysis, synthesis, generalization, explanation As a result of the study, it was established the specifics of the approach to formulating strategic goals in civil aviation cybersecurity programs in the documents of intergovernmental and international non-governmental organizations in the aviation sphere, generally based on a comprehensive vision of cybersecurity management. A comparative analysis of strategic priorities, objectives, and planned activities for their implementation revealed common characteristics based on a single methodological sense of cybersecurity as a symbiosis of five components: human capacity, processes, technologies, communications, and its regulatory support. It was found that additional branching and detailing of priority areas in the strategic documents of international civil aviation organizations (by the example of Cybersecurity Strategy and Cybersecurity Action Plan) does not always contribute to compliance with a unified methodological framework. It is argued that to develop an international civil aviation cybersecurity strategy, it is advisable to use the methodological basis of the Cyber Security Index.

Background: Neck pain is a major public health problem among sewing machine operators working in textile factories. Even though the textile industries are growing in number in Ethiopia, but there is a dearth of published studies on the prevalence of neck pain. Therefore, this study was aimed to assess the prevalence and associated factors of neck pain among sewing machine operators of garment factories in Mekelle city. Method: An institutional-based cross-sectional study design was implemented among 297 sewing machine operators' working in garment factories in Mekelle city. A systematic random sampling technique was used. Data were collected through interviews and analyzed using Statistical Package for Social Science version 23. Finally, variables with 95% confidence interval (CI): p < 0.05 in the multivariate analysis were significantly declared. Results: Two hundred ninety-seven sewing machine operators were enrolled, with 98.7% response rates. In this study, the 12-month prevalence rate of neck pain was found to be 42.3% (95% CI: 36.6%-47.9%), and variables like such as break time [adjusted odds ratio (AOR): 5.888, 95% CI: (2.775-12.493)], working hours per day [AOR: 6.495, 95% CI: (2.216-19.038)], static posture [AOR: 4.487, 95% CI (1.640-12.275)], and repetitive activity [AOR: 4.519, 95% CI:(2.057-9.924)] were associated with neck pain. Conclusion: In this study, neck pain is a major public health problem. Continuous work without break time, working greater than 8 hours per day, sitting in the same position for greater than 2 hours, and high repetitive activities were found significantly associated with neck pain. Owners and governmental bodies need to focus on developing preventive strategies and safety guidelines.

The purpose of this paper is to analyze the linkage between Si-Jeong-Chon (municipalities of Japan) catastrophic disaster recovery-regeneration plan (DRRP) and regional comprehensive plan (RCP), each of which was made after the Great East Japan Earthquake, and to make implications on establishment of a disaster recovery plan of Korea. In order to explore the relationship between the two plans, the DRRPs and RCPs of 30 municipalities are collected and categorized according to their characteristics. The results show that DRRPs of the municipalities are not always in a consistent form and contents because regulations and guidelines on DRRP are not definite and specific. The relationship between DRRP and RCP in terms of its form and contents can be divided into 3 categories; Reflective Type (RT), Complementary Type (CT), and Substitutive Type (ST). The 22 RT plans as the majority of those DRRPs appear to reflect the development strategies of municipalities' RCPs. Both 3 CT plans and 5 ST plans seem to be integrated with RCPs in some way. The plan in CT of a municipality supplements its RCP by adding some new strategies to its recovery section and the plan in ST of a municipality appears to replace its RCP. Finally the influential factors which are considered to determine linkage type are identified as remaining time which is legally required to re-establish its RCP, the extent of damage, and socioeconomic condition changes.

As high schools implement credit completion system these days, concerns about the dissolution of classes, which are the original stable groups of studying and living, and the instability of the basal space, is growing due to the extended operation of moving optional classes. The purpose of this research is to understand the effect that environmental features of the basal space within the school and the operation method have on the students' space use and formation of attachment place within the school. For this, the main activity places, attachment places, school life satisfaction and others were investigated at 2 Japanese credit-based comprehensive high schools, which are different in the physical environmental features of school buildings. Based on this, a quantitative analysis about the distribution of activity places and attachment places was implemented. The space use features for each student attribute were compared, and the school life satisfaction for each type of attachment place formation was analyzed. As a result, the change of the territorial consciousness about the class space according to the implementation of moving optional classes could be understood. And it was confirmed that the students' space using behavior and place evaluation change according to the physical environmental feature of the class space and common space, and that this is affecting the life satisfaction of students.

Purpose: The aim of this study was to assess artifacts generated in cone-beam computed tomography (CBCT) of 3 types of dental implants using 3 metal artifact reduction (MAR) algorithm conditions (pre-acquisition MAR, post-acquisition MAR, and no MAR), and 2 peak kilovoltage (kVp) settings. Materials and Methods: Titanium-zirconium, titanium, and zirconium alloy implants were placed in a dry mandible. CBCT images were acquired using 84 and 90 kVp and at normal resolution for all 3 MAR conditions. The images were analyzed using ImageJ software (National Institutes of Health, Bethesda, MD) to calculate the intensity of artifacts for each combination of material and settings. A 3-factor analysis of variance model with up to 3-way interactions was used to determine whether there was a statistically significant difference in the mean intensity of artifacts associated with each factor. Results: The analysis of all 3 MAR conditions showed that using no MAR resulted in substantially more severe artifacts than either of the 2 MAR algorithms for the 3 implant materials; however, there were no significant differences between pre- and post-acquisition MAR. The 90 kVp setting generated less intense artifacts on average than the 84 kVp setting. The titanium-zirconium alloy generated significantly less intense artifacts than zirconium. Titanium generated artifacts at an intermediate level relative to the other 2 implant materials, but was not statistically significantly different from either. Conclusion: This in vitro study suggests that artifacts can be minimized by using a titanium-zirconium alloy at the 90 kVp setting, with either MAR setting.
