Jung-Hwa Seo,Se-Jin Kim 한국스포츠과학회 2017 스포츠과학연구(JSAS) Vol.1 No.1

Most of people do not remind of 'Who is domestic medical device business?' A lot of people that Johnson and Johnson, GE and Philips and other foreign companies belong to medical device company. In fact, local enterprises small place based on world market. Local medical device industry's production has grown up rapidly last 10 years. Sales increased nearly 3 times from trillion and 500 billion KRW in 2004 to 4 trillion and 600 billion KRW in 2014. The production record constantly increased owing to safety and good quality of domestic medical devices. As many as 59% of medical devices made in Korea is exported to 198 countries in the world. Currently, medical device industry in the world has been given considerable attention. Cognition and awareness are very much low. Medical device industry, high income creating industry, is said to next generation industry to increase scale, and Korea does not follow world flow. The industry is given support from the government that is not enough. Korean enterprises have small scale among a lot of global enterprises. Being interested in development of medical devices, the author selected department of IT at college.

Nam-Su KIM(Nam-Su KIM),Won Jae SEO(Won Jae SEO) 한국스포츠과학회 2023 스포츠과학연구(JSAS) Vol.7 No.2

Purpose: This study examines the role of leaders of sport organizations from the perspectives of rank-and-file volunteers. Specifically, the study explores which factors are important in leading volunteers and how rank-and-filers interact with their leaders. Research design, data, and methodology: This study reviews a comprehensive literature on volunteer and leadership theories which are trait theory, behavior theory, and contingency theory. Given the comprehension of prior structure of knowledge on leadership, the study provides a structure of knowledge on volunteer and leadership in sport context and discusses managerial implications for leaders in sport organization. Results: With an exploration of sport leadership, this study proposes a volunteer classification model which presents four-volunteer types: professional volunteer, company volunteer, general volunteer, and school volunteer. Furthermore, this study discussed managerial implications for sport organization leaders. Conclusions: Paid employees may be prepared to accept a job and its requirements mainly due to economic benefits. Volunteers, however, do not pursue economic benefits through their activity. Different types of motivation between paid employees and volunteers bring to surface how a leader influences volunteer effectively. A conceptual volunteer clarification model could be examined in real world situations. Insights for future studies were discussed.

Purpose: This study was to investigate the effects of isometric exercise on muscle activity and body balance ability in asymmetrical walkers. Research design, data, and methodology: Twenty gait asymmetry people were divided to unilateral exercise group (UG, n=10) and bilateral exercise group (BG, n=10). UG were performed unilateral exercise for 60 minutes, three times a week, and 16 weeks, and BG were performed one side and then the other side alternately for 60 minutes, three times a week, and 16 weeks. Muscle activity and body balance ability were measured before, after 4 and 16 weeks isometric exercise. Moreover, SI (symmetry index; SI) was calculated from the measured value of SL (step length). Statistical analyses were conducted using one-way ANOVA and two-way ANOVA with repeated measures, a paired t-test, and multiple comparisons according to Scheffe. Results: In the muscle activity, ST decreased significantly in short step length(S-SL) and BG of LS compared to before isometric exercise(p<.05), and GCM decreased significantly in BG of S-SL(p<.05). As for body balance ability, the mSEBT-A difference between L-SL and S-SL was decreased significantly in UG(p<.05). And the respective total scores of L-SL and S-SL, mSEBT-PM and mSEBT-PL were increased significantly in BG(p<.05). Conclusions: As a result, in this study above, it was confirmed that isometric exercise improved muscle activity and body balance ability in asymmetrical walkers.

Purpose: This study sought to examine the symbolization of brand identity in Nike golf advertisements and to provide implications for sporting goods ads. Research design, data, and methodology: The study employed Socher’s semiotic theory to analyze characteristics embedded in Nike video advertisements. In specific, the study selected ‘No cup is safe’ among Nike video ads and analyzed structures of ad message and presented metaphors of ad messages. Results: As a study on the semiotic analysis of communication by case, this study investigated how the brand identity pursued by Nike in the advertisement is symbolized by identifying the signifier and signified in the advertisement. As a result of the study, it was possible to segment and analyze a total of 8 advertisement scenes, from the most important tee shot in golf, setting the aiming, sending to the center of the fairway, and applying the general situation of ball in and hole out to the cases of Tiger Woods and McIlroy, thereby helping the general public. Conclusions: Summary of above results showed that it was also conveying the message of metaphor and metonymy that 'I can be like Tiger Woods and McIlroy' by using Nike golf products. Further implications were discussed.

Understanding the Concept of Iron Deficiency Anemia in Athletes: A Narrative Review

Anvi RANA(Anvi RANA ) 한국스포츠과학회 2022 스포츠과학연구(JSAS) Vol.6 No.4

New insights into the aetiology of anaemia in athletes have been discovered in recent years. From hemodilution and redistribution, which are thought to commit to so-called “sports anaemia,” to iron deficiency triggered by higher requirements, dietary requirements, decreased uptake, enhanced losses, hemolysis, and sequester, to genetic factors of different types of anaemia (some related to sport), anaemia in athletes necessitates a careful and multisystem methodology. Dietary factors that hinder iron absorption and enhance iron bioavailability (e.g., phytate, polyphenols) should be considered. Celiac disease, which is more common in female athletes, may be the consequence of an iron deficiency anaemia that is unidentified. Sweating, hematuria, gastrointestinal bleeding, inflammation, and intravascular and extravascular hemolysis are all ways iron is lost during strength training. In training, evaluating the iron status, particularly in athletes at risk of iron deficiency, may work on improving iron balance and possibly effectiveness. Iron status is influenced by a healthy gut microbiome. To eliminate hemolysis, athletes at risk of iron deficiency should engage in non-weight-bearing, low-intensity sporting activities.

Ze Won KIM,Myung Seok SEO,Jung Won LEE,Hwang Woon Moon 한국스포츠과학회 2022 스포츠과학연구(JSAS) Vol.6 No.3

Purpose: The purpose of this study is to provide basic data for developing an educational program that can be practically applied in the field of survival swimming education. Research design, data, and methodology: This study reviewed prior literature including governmental reports, journal articles related to survival swimming programs at home and abroad. Based on the basic data collected through literature, domestic and foreign educational institutions and national educational programs were cataloged and analyzed. Results: The study found that among the goals of swimming education, the prevention of water accidents and the cultivation of water safety skills along with improving swimming ability are very important educational goals. Currently, domestic survival swimming education programs are divided into classes and training sessions, so it is necessary to develop an educational program according to each individual's swimming ability and a unified and systematic program through education for each level of survival swimming learners. Conclusions: It is thought that the reinforcement of the leader's capacity for quality improvement will have a positive effect for the development of survival swimming. Further implications were discussed.

Nam-Su KIM,Min Soo KIM,Won Jae SEO 한국스포츠과학회 2022 스포츠과학연구(JSAS) Vol.6 No.2

Purpose: This study attempts to investigate causal and intervening conditions for sport participation of Korean immigrants in the United States. Research design, data, and methodology: Grounded theory approach was used to develop a conceptual framework that presents the psychosocial processes that occur in immigrants’ experience of sport participation. Participants were selected purposefully for information-rich cases. Korean immigrants with current experience of having periodically participated in sports were the criterion for sample selection. Based on selection criteria, 9 Korean immigrants took part in interview. The interview discussions were taped and transcribed verbatim into a Word file. The process for data analysis included four grounded theory approaches of purposive and theoretical sampling, an open and axial coding, memo writing, and finally the development of the conceptual framework. Results: Six concepts were revealed in the causal conditions that facilitate the process of immigrants’ sport participation in the states: Personal experience, significant others, personality, physical environment, psychological well-being, and social connection. Three concepts were revealed as the intervening conditions that block the process of immigrants’ sport participation in the states: Conflict with cultural change of organization, Pressure at workplace, and Economic constraints. Conclusions: Conceptual model presents causal and intervening factors. Further implications were discussed.

Chae Yun OH,Seung Eun HUR,Youn Sang SONG,Hwang Woon MOON 한국스포츠과학회 2021 스포츠과학연구(JSAS) Vol.5 No.3

Purpose: The purpose of this study is to examine the relationship between the leadership style and performance of university athletes leaders. Research design, data, and methodology: This study utilizes survey items constructed by reserach variables. Data were collected from college athletes of universities in Seoul and Gyeonggi-do, where sports teams are located. A convenient sampling method was used of non-probability sampling methods. A total of 314 responses were computed at statistic program, spss version 21.0. In specific, the study employed correlation, exploary factor analysis, mulple-regressions to test the effects of ledership types on performance. Results: As a result of an empirical analysis to examine the relationship between the leader s leader-ship style and the athletic performance of college athletes, it was found that the leader s leadership style had a significant effect on the college athletes performance. Conclusions: A leader s leadership style is a very important factor for college athletes who enter the professional world after graduating from college. Therefore, coaches maintain a horizontal relationship with the players rather than a vertical one, and if a leadership style suitable for the players is applied, the players performance will be better, and the development potential of players and teams will increase. Suggestions for future studies were discussed.
