Sports drinks help optimize and improve performance by delaying and eliminating the buildup of fatigue-causing substances in the body during exercise. Saengmaeg-san is a nature-friendly traditional beverage that has no side effects on the human body and can quench thirst. However, studies on the relationship between exercise ability and Saengmaeg-san are insufficient. The purpose of this study was to prescribe Saengmaeg-san during the summer training period of 4 weeks and to analyze the effect on body composition and exercise performance. Seventeen male participants were divided into 3 groups (Saengmaeg-san acid intake group [n=9], placebo group [n=8]), and body composition (height, weight, muscle mass, fat mass, BMI) and conducted exercise performance (total exercise time and HRmax). In our study, Saengmaeg-san intake had a positive effect on exercise performance, such as decreased body fat percentage, increased exercise time, and decreased HRmax. Therefore, Saengmaeg-san showed the potential as a sports drink. In the future, additional studies on fatigue-related substances, immune function-markers, and blood lipids are needed in order to clearly explain the change in exercise performance due to consumption of Saengmaeg-san.

From the perspective of smart learning space, this study aims to take a look at the learning space of college students who do online remote learning in the COVID-19 era, and analyze their demands on what smart learning space they want. Furthermore, this study intends to provide valuable implications for the technology-enhanced learning environments by deriving design elements that make up the university's smart learning space. To achieve these goals, we conducted a review of prior studies, interviews with experts, and case analysis on smart learning spaces of major Korean and foreign universities, which are considered as innovative cases. Additionally, in order to confirm the difference between the importance level recognized by the college students and the current performance level for nine components of technology and for ten components of spaces and facilities, a paired t-test and an Importance-Performance Analysis (IPA) were carried out. According to the result of IPA analysis, Internet of Things from the technological aspects, a desk that can supply power and a flexible learning space from the aspects of spaces and facilities were found to have much lower performance than the importance. This result is meaningful in suggesting key design components for smart campus development in the post-COVID-19 world.

Purpose: This paper reviews the attitudes of consumers related to the consumption crisis response strategy (i.e., defensive vs. receptive) that companies implement during crises. Research design, data, and methodology: We discuss the interaction between the crisis response strategy and the consumption crisis type (i.e., corporate ability vs. corporate social responsibility). We used SAS ver. 9.4 software to analyze the results. We applied a 2 × 2 intergroup experimental design to our sample of subjects, who were undergraduate and graduate students at a university in Seoul, South Korea. The three experimental variables considered were the entity's risk response strategy, the crisis type, and public relations strategy. The experiments were conducted by presenting a hypothetical scenario to eight groups. Prior to this experiment, five preliminary surveys were conducted to determine the three variables just mentioned. Preliminary surveys were conducted on the basis of these criteria. For eight selected product lines, 320 undergraduates were required to enter the product lines that are frequently used in the assessment center up to the fourth priority. Results: Analysis of variance revealed that experiments related to crisis response strategy, type of enterprise crisis, and type of public relations message were successful. Conclusions: Our results verify the impact of different types of social initiatives on distribution marketplaces.

Recently, as the status of South Korean popular culture has risen, the Korean Wave is gaining popularity not only in Asia but also in Europe, America, and South America, and is currently at the center of the global cultural phenomena. Among them, in particular, the cultural content industry has been developing rapidly thanks to the Korean Wave. Currently, the Korean Wave is spreading all over the world while bringing about positive effects to South Korea. In fact, until 2017, political and social issues such as 'North Korea/North Korean nuclear weapons' and 'Korean War' were considered as the images associated with South Korea, but from 2018, it has been shown that all images associated with South Korea are cultural content except for 'IT industry'. Given the economic effects that can be obtained not only from the positive associated images of South Korea per se but also from the complex action with various industries in South Korea, the craze for the Korean Wave can be viewed as affecting the overall national prestige of South Korea. For the steady vogue of the Korean Wave, thorough investigation of the Korean Wave and understanding of the expectations of consumers of the Korean Wave seem to be necessary

Purpose: The purpose of this study was to develop the dietary approaches to stop hypertension (DASH) diet education program tailored to Korean adults and to examine the effect of the DASH diet education program on bone mineral density in middle aged women. Methods: The subjects of this study were 26 middle aged women, pre and post menopause, who attend a church located in Kyung-In district. The DASH group I (n=13) was provided with the DASH diet education program only, while the DASH group II (n=13) was provided with DASH diet education program along with calcium supplements (1 g/day). The DASH diet education program included one lecture on DASH diet, one face to face counseling, and five telephone counseling sessions during the 8 weeks period. Results: The knowledge and subjective compliance level of DASH diet increased significantly in both groups, at 4 and 8 weeks after the intervention. The level of objective compliance of DASH diet in both groups increased over the study period, but it was not significant as compared to those of the baseline. Bone mineral density of both groups decreased at 8weeks as compared to the baseline after the intervention. Conclusion: Although 8weeks of DASH diet education program increased the knowledge and compliance of DASH diet, it was not effective to bring the changes in bone mineral density among the middle aged women.
