  • Objectives: The purpose of this study was to identify the health promotion activities of the elderly Korean aged 65 or older and to examine the related factors associated with the health promotion activities. Methods: Data were obtained from 2008 Social Statistics Survey of Korea National Statistical Office of 6,207 people aged 65 or older. We measured the socio-demographic characteristics, physical health status, social health status, and health promotion activities. Statistical analyses were employed through the $X^2$-test and Odds ratio using Logit Model. Results: In our study, health promotion activity practice rates were varied among the socio-demographic characteristics, physical and social health status. Our findings also support that better socio-demographic and physical health status explain the higher practice rates of health promotion activities. In addition, the higher social health status was associated with better practice rates of health promotion activities. Conclusion: We found that the health promotion activities of the elderly could be encouraged by better socio-demographic status and physical and social health status. To better accomplish the health promotion for the elderly in our community, policy-makers should need careful political deliberation for executing health promotion services considering the distinctions of programme and target groups.

  • This study examines the effect of satisfaction with adolescent extracurricular activities on social withdrawal with a focus on the mediating effect of self-esteem and sense of community. We used data from the 3rd wave (2012) of the Korean Children and Youth Panel Survey (KCYPS) collected by the National Youth Policy Institute for path analysis. Participants were 1,139 first year middle school students who participated in adolescent extracurricular activities. First, the degree of satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem. Second, satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via a sense of community. Lastly, satisfaction with adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem and a sense of community. The research findings indicate that the level of social withdrawal is less when adolescents are satisfied with adolescent extracurricular activities and have a high level of self-esteem and sense of community. The results demonstrate that a satisfactory level of adolescent extracurricular activity would help adolescents decrease their social withdrawal by increasing the level of self-esteem and sense of community.

  • Purpose: Corporate management is under pressure to contribute to social values beyond profit-seeking, and interest in ESG (Environment, Social, Governance) is increasing worldwide. In the recent global climate change crisis and the COVID-19 pandemic, the importance of non-financial values such as ESG is increasing. Therefore, the purpose of this study is to prepare a strategy for future ESG management activities by analyzing the impact of it on corporate performance by food companies. Research design, data and methodology: ESG-related research trends, ESG activities, and corporate performance were analyzed. After that, a regression analysis was conducted to identify the relationship between ESG evaluation grade and corporate performance. Result: ESG management activities measured by ESG scores did not significantly affect the return on assets, one of the variables of corporate performance. However, as a result of setting the return on equity as a dependent variable, ESG management activities have a nonlinear relationship with corporate performance, and ESG management activities have a positive effect on corporate performance when investment in ESG management activities is reasonable. Conclusions: These results show that food companies should engage in an appropriate level of ESG management activities to improve corporate performance.

  • The social responsibility of fashion companies has become a crucial factor considering company image and awareness. Businesses have thus increased their CSR activities. However, few studies have shown clear and consistent results regarding the effectiveness of CSR activities. Therefore, this study focuses on the evaluation of the direct effect of CSR on trust and corporate reputation including its moderation by consumer's perceived fit and motivation. A total of 284 completed questionnaires were obtained from adult consumers in the fashion market with promotional leaflets for CSR activities as stimuli. The results were as follows. First, the dimensions for CSR activities were categorized as follows: Social welfare responsibility, environment protection, economic responsibility, social regulation compliance, customer protection, and culture and arts support. Further social regulation compliance, and economic and social welfare responsibilities positively affected corporate trust and reputation. Second, the main effect of perceived CSR activities and fit on corporate trust and reputation was significant, and the interaction effects of the social welfare, environment protection, and culture and arts support of CSR activities and fit were significant. Finally, the interaction effect of perceived CSR activities and motivation on corporate trust and reputation was not significant, but the main effect was significant. Implications of how to manage and enhance the effectiveness of CSR activities are offered.

  • Recently, global competition in the manufacturing sector is driving firms in the manufacturing sector to conduct product innovation projects to maintain their competitive edge. The key points of product innovation projects are 1) what the purpose of the project is and 2) what expected results in the target market can be achieved by implementing the innovation. Therefore, this study focuses on the performance of innovation projects with a business viewpoint. In this respect, this study proposes the "achievement rate" of product innovation projects as a measurement of project performance. Then, this study finds the best strategies from various innovation activities to optimize the achievement rate of product innovation projects. There are three major innovation activities for the projects, including three types of R&D activities: Internal, joint and external R&D, and five types of non-R&D activities - acquisition of machines, equipment and software, purchasing external knowledge, job education and training, market research and design. This study applies decision tree modeling, a kind of data-mining methodology, to explore effective innovation activities. This study employs the data from the 'Korean Innovation Survey (KIS) 2014: Manufacturing Sector.' The KIS 2014 gathered information about innovation activities in the manufacturing sector over three years (2011-2013). This study gives some practical implication for managing the activities. First, innovation activities that increased the achievement rate of product diversification projects included a combination of market research, new product design, and job training. Second, our results show that a combination of internal R&D, job training and training, and market research increases the project achievement most for the replacement of outdated products. Third, new market creation or extension of market share indicates that launching replacement products and continuously upgrading products are most important.

  • The purpose of this study was to determine the optimum extraction method suitable for the availability of biological activities in unripe apples known to be rich in functional components. Unripe apples 'Hongro' picked on May 28th, 2019 were extracted by various extraction methods (hot water, ethanol, enzymatic pre-treatment, ultrasonic wave, and subcritical water) and their extracts were investigated yield, effective component contents, and antioxidant activities. Overall, the yields by the extraction solvent were higher in water than in organic solvent(ethanol) because water-soluble compounds were eluted from a polar solvent. Total phenol contents of the ultrasonic wave (ethanol) extracts were significantly higher in 6 times than hot water extract. Contents of flavonoid were highest in the ethanol extract at 29.14 mg QE/g. Contents of tannin and ursolic acid were also significantly higher in the ultrasonic wave (ethanol) extract. The DPPH radical and ABTS radical scavenging activities were the strongest in the ultrasonic wave (ethanol) extract. Correlation between effective components and antioxidant activities was high in the total phenol content with ABTS and the ursolic acid content with DPPH (p<0.01). The above results suggested that ultrasonic wave (ethanol) extract of unripe apples has the potential to act as a functional material.

  • The major objective of this study was to investigate the usability as cultivar for processing of new Citrus hybrid 'Hamilgam'. We investigated various antioxidant activities, such as DPPH radical, ABTS radical, Hydroxyl radical and Superoxide anion radical effect, along with total polyphenol content and total flavonoid content of Citrus hybrid 'Hamilgam', C. unshiu, C. natsudaidai. The total polyphenol content and total flavonoid content were the highest in the Hamilgam. The major flavonoids of Hamilgam and Natsudaidai were naringin and neohesperidin, and those of Unshu were narirutin and hesperidin, as determined by HPLC. Especially, the neohesperidin content of Hamilgam showed much higher (100 times over) than that of Unshu. However, the aglycone form was not found. DPPH and ABTS radical scavenging activities were the highest in Hamilgam peels. Hydroxyl radical scavenging activity was high in the order of Unshu, Hamilgam and Natsudaidai. Superoxide anion radical scavenging of 3 cultivars peels displayed low activities compared to DPPH and ABTS radical scavenging. Based on these results, Hamilgam peel extracts possess antioxidant activities and may thus serve as potential sources of functional food, cosmetic products, etc.
