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.

Objective: Patients with chronic obstructive pulmonary disease (COPD) may experience reduced physical activity and quality of life (QoL) due to decreased pulmonary function. The purpose of this study was to investigate the level of pulmonary function, physical activity, and QoL of COPD patients. Design: Cross-sectional observational study. Methods: This study examined the published data of the Korea National Health and Nutrition Examination Survey in 2015-2019. Among 39,759 subjects who participated for 5 years, data from 151 patients diagnosed with COPD were analyzed separately. For the pulmonary function, the results of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV6, forced expiratory flow 25-75%, and peak expiratory flow were observed. Physical activity was identified as frequency and duration. For the QoL, EQ-5D-3L evaluation results were examined, and the frequency and index of the Korean version were investigated. Results: In pulmonary function, all variables were found to be lower than age and weighted matched normal values. COPD patients showed to perform very low levels of high/medium physical activity and sitting time was confirmed to be more than 8 hours a day. In QoL, it was found that the highest reporting rate of some problems was the "pain and discomfort" and "mobility". Conclusions: It was found that COPD patients showed that the prevalence of circulatory disease was relatively high, lowered pulmonary function, and QoL. These can be improved through regular physical activity, and it is thought that this can be achieved through optimization of pulmonary rehabilitation.

최근 들어 경쟁력 향상을 위해 많은 기업들이 기간 정보 시스템을 도입하여 운영하고 있는 추세이다. 도입된 정보 시스템의 활용도를 향상시키기 위해서는 정보 시스템 사용 현황을 실시간으로 모니터링/분석할 수 있는 체계를 갖추는 것이 필수적인데 현재 대부분의 기업 정보 시스템들은 이러한 체계적인 모니터링 기능을 제공하고 있지 않고 있는 실정이다. 본 연구에서는 이를 위해 정보활동 모니터링 (IAM: Information Activity Monitoring) 프레임워크를 제안하고 이를 실사례를 통해 그 유용성을 보인다. IAM은 기업 내의 중요한 정보 처리 활동을 실시간으로 모니터링하고 분석하여 그 결과를 사용자에게 피드백 하는 행위라고 정의되며 기업의 정보 처리 행위에 관한 4가지 주요한 시각 (업무 프로세스, 데이터, 사용자/조직, IT 시스템)에 관한 요약 정보를 제공한다. 제안된 '정보활동 모니터링' 기능은 항공기 부품을 생산하는 기업의 설계/생산 통합 정보 시스템의 한 모듈로 개발되어 운영되고 있으며 이러한 기능은 특히 정보 시스템 도입의 필요성에는 공감하나 지속적인 운영에 필요한 인력과 시간이 부족한 중소기업의 정보 시스템 활용도 향상을 위한 필수적인 기능이라 판단된다.

Background: Happiness is one of the most important indicators of health, wellbeing, and quality of life among older adults. The objective of the study was to investigate factors associated with happiness among senior citizens residing in rural areas using the 2017 National Survey of Older Koreans. Methods: A cross-sectional analytical study was conducted among 3,149 senior citizens living in rural areas using secondary data from the 2017 National Survey of Older Koreans. Happiness was measured by a single question and responses were recorded dichotomously. Descriptive and inferential statistics were computed at a 5% level of significance. Results: In all, 64.5% of the participants considered themselves as happy most of the time in the last 1 week. In the study, socio-demographic factors did not predict happiness except age. Satisfaction with a health status, financial situation, relationship with children, cultural satisfaction, and satisfaction with friends and society were positively associated with happiness among senior citizens residing in rural areas of Korea. Odds of reporting happiness were higher among those who traveled in the last 1 year, visited elderly welfare centers, and were involved in voluntary work than among those who did not. Conclusion: Happiness among senior citizen was significantly associated with life satisfaction with regard to health, finance, relationship with family, friends and society, and social activity participation.

Isoflavones have received much attention because of their health-related and clinical benefits such as estrogenic and anti-oxidative activities as well as triggering of natural killer cell activity. However, there are few publications reporting the pharmacokinetic profiles together with physicochemical properties of main isoflavones. Therefore, the pharmacokinetic parameters of main aglycones, daidzein, glycitein and genistein after oral administration of soybean extracts were investigated and the physicochemical properties of soybean extracts were characterized. It was observed that angle of repose was $46^{\circ}$ and tap density, bulk density and porosity were 10.12, 4.3 and $0.86\;g/cm^3$ and the mean $AUC_{last}$ of daidzein, glycitein and genistein was $11.376\;{\mu}g{\cdot}h/mL$, $3.045\;{\mu}g{\cdot}h/mL$ and $0.825\;{\mu}g{\cdot}h/mL$, respectively. Cell viability was 60% at a concentration of 10 mg/mL. Taken together, it was suggested that isoflavones were contained in the soybean products and had an antioxidant activity and this study would be the basis to control the quality of soybean products and study of the bioequivalence between soybean products in future.

Objectives: We aimed to examine the effects of various leisure activities on cognitive impairment in young-old (aged 65-74 years) and old-old (aged ${\geq}75$ years) adults. Methods: In total, 10,279 elderly Korean individuals from the 2014 Korean National Survey on Older Adults' cohort were enrolled in our study. Cognitive impairment was assessed using the standardized score of the Mini-Mental State Examination for Dementia Screening, whereas leisure activities were recorded via self-reporting of the extent and type of leisure activity the subjects involved in over the past year. Multivariate logistic regression was used to assess the effect of leisure activities on cognitive impairment, while controlling for potential covariates. Results: The subjects were more likely to participate in cognitive activities than in non-exercise physical activities. After controlling for selected covariates, involvement in cognitive activities was found to be a significant predictor of cognitive impairment in both the groups, whereas involvement in non-exercise physical activities was not a predictor of cognitive impairment in individuals aged ${\geq}75$ years. Moreover, depressive symptoms, rural residence, and hearing difficulties were common predictors of cognitive impairment among elderly-Korean-individuals. Conclusion: Leisure activity involvement may help delay cognitive impairment, which is often concomitant with aging. Hence, an early intervention service may significantly benefit both young-old and old-old individuals.

Postmenopausal women aged 50s generally experience gradual changes in body such as decline in antioxidant and estrogen levels as the body ages. To overcome these aging-associated changes, the needs for health functional foods are increasing. Dendropanax morbifera (DM) have antioxidant effects, anti-inflammatory against cancer cells, antidiabetic, and antiatherogenic effect which are associated with postmenopausal symptoms. We analyzed clinical effects of DM on aging-related symptoms by reporting their antioxidant, anticancer and inflammatory activity, etc. and their bioactivity. Data sources EMBASE, SCOPUS, PubMed, Web of Science, and Google Scholar databases were searched up to August 2016 for studies investigating medicinal plants in prevention and treatment of diabetes. The search terms were "Dendropanax morbifera". The reference lists of articles were also reviewed for additional relevant studies. Extracts of DM have various efficacy such as antioxidant, anti-cancer, anti-inflammatory activity and anti-thrombotic effect.
