  • Purpose: This study was conducted to measure the relationships between ecological factors and Navy personnel's physical activity (PA) based on McLeroy's Ecological model. Methods: A cross-sectional survey was conducted with a convenience sample of 184 Navy personnel working in 10 Navyships. A self-reporting questionnaire consisted of measures of intrapersonal, interpersonal, organizational and community factors related to Navy personnel` s PA. Data were analyzed by descriptive statistics, $x^2$-test, t-test, analysis of variance, and hierarchical multiple regression using SPSS/WIN 17.0 programs. Results: Their mean PA level was $2,848.1{\pm}3,344.5$ MET-min/week, and mostly moderate level (50.5%). Hierarchical multiple regression analysis showed that religion, working department, working type, perceived health status and community environment were significant PA correlates. Conclusion: Community environmental factors as well as intrapersonal factors were significantly associated with Navy personnel's PA, indicating that community health nurses should expand an approach for individual-level behavioral change to incorporate Navy personnel specific community environmental barriers into PA interventions.

  • 고감미 다수성 계통인 자가수정 스테비아의 hypocotyl 절편체를 이용하여 대량증식방법 개발에 대한 결과는 다음과 같다. 선발된 자가수정개체는 초장이 72.0~120.7 cm로 분포되어 있었고, 분지수는 4.9~56.6개로 분포되어 있었다. HPLC 분석을 통하여 rebaudioside-A(RA)성분이 평균함량 55.2%이상 함유된 자가수정 개체를 선발하였다. 스테비아의 hypocotyl 절편체를 이용하여 MS배지에 1.5 mg/L BA와 0.5 mg/L Kinetin를 혼용 첨가하였을 때 가장 많은 식물체가 재분화되었다. 이는 1개의 절편체가 30개의 식물체 재분화 효율을 나타내었다. 재분화된 신초로부터 발근배지는 0.1 mg/L IBA가 첨가된 배지에서 가장효과가 좋았다. 발근된 신초는 기외 이식 후 순화과정을 통하여 정상적인 식물체로 생육하였다. 본 연구에서 구명된 대량번식방법은 Rebaudioside A 생산성 향상에 효과적으로 이용될 것으로 판단된다.

  • This study investigated social determinants and their interaction effects on the health of school-aged children in diverse environmental factors pertaining to the individual, family, and peers from an ecological systematic perspective. Data were drawn from the first wave of the Korean Children and Youth Panel Survey (KCYPS) developed by the National Youth Policy Institute and conducted in 2010. Data were analyzed by descriptive statistics, Cronbach ${\alpha}$, correlation, and hierarchical regression analysis using SPSS ver. 18. The results from this study showed that sex and age were related to the health of school-aged children, as social determinants. Self-rated levels of the health of boys and younger children were more positive than girls and older children; in addition, levels of self-resilience, satisfaction of peer relation, and parenting rearing attitude were found to have a positive impact on self-rated levels of the health of school-aged children as protective factors. Especially, according to the result of interaction analysis between factors, self-resilience, and parenting rearing attitude were moderators of the effects on between sex and household income and self-rated level of the health of school-aged children respectively. The findings from this study suggested the need to expand the social intervention range to improve school-aged children's health.

  • Purpose: This study was done to develop a predictive model for quality of life of elderly residents in long-term care facilities (LTCF). The study was based on Brofenbrenner's ecological system theory and a literature review. Methods: Data were collected using a convenience sample of 205 elderly residents in 2 nursing homes located in D city and 1 nursing home located in K province. The exogenous variables were individual factors, family support, and facility environmental factors. The endogenous variables were self-esteem, accommodation adaptation and quality of life of elderly residents in LTCF. Collected data were analyzed through structural equation modeling using AMOS 20.0. Results: Eleven of the twelve hypotheses were supported, but the hypothesis that facility environment factors effect self-esteem was not supported. Quality of life of elderly residents in LTCF was explained first by facility environmental factors, followed by self-esteem, individual factors, accommodation adaptation, and family support with an explanatory power of 83.0%. Conclusion: To improve the quality of life of elderly residents in LTCF, the service and environment preparation provided by facilities is important, and it is necessary to provide emotional counseling to improve the self-esteem of these elders.

  • The purpose of the study were two fokls: to investigate causes of wife abuse through both husbands and wives as the research subject and through ecological perspective as a theoretical framework. Data were collected using self-reporting questionnaires distributed to 400 couples in Seoul and Taegu. 280 questionnaires were used in the final analysis. The major findings of the study were summarized in the following. First, the percentage of samples who reported one or more instances of acts in each scale was 84.3%(236 couples). They reported having been a vicitm of abuse by their partners at least one instance in the preceding 12 months. Secondly, the hierarchical and stepwise regression yielded the result that wife abuse behavior by husbands was influenced by husband's microsytem(e.g.job stress, marital satisfaction, education level and occupation) and organism variables(e.g. husband's perceptions about the violence level of mass media, childhood observation of parental violence, childhood experience of the battering). These variables accounted for 38% of variance of wife abuse behavior among Korean husbands.

  • This study aims to enhance the engineering education for non-majors by incorporating the concept of Global Citizenship Education and addressing the need for education that responds to climate and ecological changes. The study uses robot programming as a tool to foster the development of global citizens. Non-majors often struggle with producing more than just motionless forms or solid productions, due to a lack of understanding of mechanisms and coding. The study proposes the use of the Convergence D-SteamRobot (DSR) to address this issue by blending humanities and engineering. This is achieved by presenting problems through books to increase empathy, integrating simple machine mechanisms, and creating prototypes to solve self-defined problems. Through this process, learners determine the SDGs topic they want to solve and learn about the simple mechanical mechanism involved in producing the prototype. The educational model provides a constructivist learning environment that emphasizes empathy and exploration, encourages peer-learning, and improves divergent thinking and problem-solving skills.
