The purpose of this study was to examine the influencing factors of job engagement among Korean police officers. This was the secondary analysis of data from the 5th Korean Working Conditions Survey (KWCS). The study subjects included 185 Korean police officers. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and multiple regression with IBM SPSS Statistics 24.0 program. Job insecurity (${\beta}=-.34$, p<.001), job reward (${\beta}=.39$, p<.001), subjective health status (${\beta}=.22$, p<.001), and organizational justice (${\beta}=.20$, p=.002) were significant influencing factors on job engagement, explaining 59.3% of the variance (F=34.26, p<.001). Effective and systematic strategies to improve Korean police officers' job engagement should focus on job reward, job insecurity, subjective health status, and organizational justice. The results of this study can be utilized as base data to improve Korean police officers' job engagement.

This study is a descriptive research study to investigate the effect of core basic nursing practice education on clinical competence of nursing students. The data was collected from 169 3rd and 4th grade students in the Department of Nursing, College of Nursing, G province. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, multiple regression. Core experience is negatively correlated with performance confidence (r=.446, p<.001) was negatively correlated with clinical performance (r=-.206, p=.001). It was found to have a negative correlation with (r=-.346, p<.001). In this study, the factors affecting clinical performance were self-confidence (${\beta}=-.317$, p<.001), and clinical performance was 11.3%. Therefore, effective practical education program for improving clinical performance is needed for smooth practical education of nursing students.

This study is a descriptive study for analyzing cigarette warning picture and message effect according to smoking status (smoking, non-smoking, ex-smoking). A total of 219 subjects participated in the study. Data collection was conducted from June 4, 2017 to June 14, 2017. The survey was conducted by using the 10 cigarette warning pictures(heart disease, stroke, lung cancer, laryngeal cancer, oral cancer) and cigarette warning messages selected by the Ministry of Health and Welfare in 2016. The results of the study showed that there was a statistically significant difference in smoking cessation intention between smoking, non-smoker and ex-smoker groups after exposure of smoking warning picture and cigarette warning message(F=36.08, p<.001). Therefore, it is suggested that the contents of cigarette warning picture and warning messages including T.V Anti-Smoking Public Service Announcement need to be replaced regularly in order to improve the smoking cessation of smokers according to National Health Promotion Act.

This study was conducted to predict sociocultural psychological variables affecting successful aging of the elderly. The participants were 187 elderly people aged at least sixty who used 16 elderly welfare centers in G metropolitan city and J and S city from december 2018 to january 2019. Data analysis was done by using SPSS WIN 23.0 program, for one-way ANOVA, independent t-test, pearson correlation coefficients and multiple regression. This study showed a positive correlation between successful aging and basic psychological need, ego-integrity, cultural competence. The ego-integrity(${\beta}=.372$, p<.001), cultural competence(${\beta}=.410$, p<.001), relationship(${\beta}=.168$, p=.003) have a 71.1% explanatory power for the successful aging of the elderly. It is necessary to develop sociocultural psychological programs to promote self-integration, cultural competence, and relationship for successful aging of the elderly.

This study aimed to identify the self-rated health and its associated factors of the elderly. Study subjects were community-dwelling elderly of 60 or more. Survey was done by using questionnaire including general characteristics, lifestyle, and health related variables. Blood pressure, anthropometric variables, lipid profiles, and fasting glucose were checked. Descriptive statistics showed that good self-rated health was 78.2% in the elderly. Multiple logistic regressions revealed that good self-rated health was associated with disease(OR:10.83, 95% CI:2.47-47.43), depression(OR=2.50, 95% CI=1.20-5.18), and exercise(OR=3.01, 95% CI=1.40-6.47). Therefore, health promotion program considering associated factors of self-rated health should be developed.

This paper presents development status of sounding rockets containing scientific payload and telemetry at home and abroad. The case of outside, United States is launching sounding rockets in 20-30 flights per year by the NASA program which offers to carry payload weights of 38-680 kg and altitude of 88-1500 km. Europe is launching in 4-5 flights per year by the ESA program. The case of Korean sounding rockets was successful with the launch of three times(KSR-I,II,III), but Korea lags far behind the advanced countries in the field of development technologies for space launch vehicle. We expect that our scientific and industrial technologies will be improved through the research and development of sounding rockets. In this study we proposed necessity and future direction of development in domestic sounding rockets.

Verification, Validation & Accreditation (VV&A) process is widely applied in various disciplines as a method of acquiring the credibility for M&S tools. The guideline of VV&A states that the detailed process can be established flexibly according to the needs and the availability of resources. For example, DAPA (Defense Acquisition Program Administration) guideline suggests that the accreditation process in the VV&A can be omitted if necessary. On this study, we first introduce and describe V&V process. Accreditation process is omitted due to limited time and resources. However, the proposed V&V is sufficient for our needs. Finally, we apply the proposed process of V&V to the System-Integrated Simulator of "Raybolt", Medium-Range Infantry Missile System, for the acquisition of the M&S credibility.

Background/Objectives: The purpose of this study is to investigate the effects of eating habits and self-efficacy on health promotion behavior and to improve the quality of life in each life cycle. Methods/Statistical analysis: This study is a narrative research study for nursing students at university B in C city. The data were analyzed by SPSSWIN 18.0, t-test, ANOVA and bonferroni post test, Pearson correlation coefficient calculation and multiple regression analysis. Findings: Health promotion behaviors were positively correlated with eating habits and self-efficacy. Multiple regression analysis showed that 53.8% of the parents, caregivers, health status, eating habits, and self - efficacy of the nursing students showed the health promotion behaviors of the nursing students. The higher the self-efficacy(t=6.06, p<.001), the better the health-promoting behaviors(t=3.28, p=.001). Application/mprovements: Development of programs for strengthening health education and self-efficacy is required for proper eating habits and health promotion.

It showed differences in educational status, osteoporosis management training experience, residents number and importance awareness of elderly bone health. And prevention activities differed according to osteoporosis management training experience and importance awareness of elderly bone health. There was a positive correlation between knowledge and prevention activities of osteoporosis. Therefore, it is necessary to develop education programs for the management of elderly osteoporosis and to raise importance awareness of elderly bone health among care providers in nursing home. Further studies are needed to evaluate the effects of the program.
