Purpose The purpose of the study was to perform a comparative analysis of the YANG Hak Seon technique carried out by "K" athlete with the kinematical data of "Y" athlete and propose a method to improve the YANG Hak Seon technique of "K" athlete. Method The subject recruited for the study was a male athlete from Korean national team (Age: 21, height: 1.65 m, body weight: 59.6 kg, and career: 11 years). Four high - speed cameras were used to analyze the 3D motion of the YANG Hak Seon technique performed by "K" athlete. The variables selected for analysis were the velocity of COM, displacement of COM, the rotational & torsional angle of the trunk and rotational & torsional angular velocity of the trunk. The results obtained were compared to the preexisting data of the "Y" athlete (data set from the published research). Results Firstly, the horizontal displacement of the YANG Hak Seon technique of the "K" athlete was observed to be shorter along with lower vertical displacement during landing compared to “Y” athlete. In addition, the overall horizontal velocity was low and vertical velocity was not generated which rises during the BC (board contact) phase. Although the rotational angular velocity of the trunk was lower during the BC, HC (horse contact) phase and LD (landing) phase, torsional angular velocity was higher during the LD. Conclusion In order to improve the completeness of the YANG Hak Seon technique of the K player, it is necessary to enter with a fast and low posture on the footplate during the initial phase. In the BC phase, it is essential to raise the COM simultaneously while landing on the footplate and increase the rotational angular velocity of the trunk.
A number of global cities and local cities facilitate local economies and development by utilizing sports. However, their strategy is likely to be a short-term and one-time policy, which does not continuously strengthen their development. Therefore, the use of sports needs to be considered as more specific and longer term strategies for local development. This study examines the concept and role of sports city focused on cases of overseas sports cities, and successful and ideal cases of background and features of sports cities were analyzed to promote and lead the direction of improvement of sports cities in Korea. Consequently, strengthening a city’s sport capability and connecting it to local development need to be met to become a city into a successful sport city. To do so, it should premise recognition that sports cannot be treated separately from other urban policy area and it needs to invest in sports facilities, hosting sports events and competitions, and sports clubs based on the recognition for the importance of sports. Moreover, it needs a marketing strategy for branding and differentiation through sports of a city’s expertise. Finally, to make sports act as a catalyst to strengthen the process of an integrated city’s competitiveness, it requires a local government’s strong leadership and organization capacity of stakeholders.
PURPOSE This study aimed to explore the re-socialization process of college soccer players who rejoin college soccer clubs after dropping out. METHODS A case study approach was employed, and participants were selected using the snowball sampling method. Data were collected through in-depth interviews, participant observation, and literature reviews. The authenticity of the data was validated through triangulation, member checking, and peer debriefing. All research procedures were conducted following approval from the institutional review board. RESULTS The study revealed several key findings. First, participants faced numerous challenges during the re-socialization process into sports, including interpersonal, academic, and emotional difficulties. Second, distinctive features of the re-socialization process emerged, including the determination and effort required for adapting to university life, support from socialization agents within the university, and rapid re-socialization following dropout. Third, experiences within collegiate soccer clubs indicated low barriers to entry for former athletes, academic success through complementary relationships, a hierarchical culture familiar to student-athletes, and enhanced satisfaction in interpersonal relationships and a sense of belonging. CONCLUSIONS This study underscores the importance of institutional support that enables college athletes to participate in sports clubs, facilitating the successful re-socialization of athletes who have dropped out.
Purpose The purpose of this study is to overcome the shortcomings of 109C(Forward 4 ½ somersault) skill(Level 3.7) for two members of the men’s national diving team(YHR, KYN). Methods For qualitative analysis of the performed skill, three high-speed cameras and water-attached EMGs consisting of a total of ten placements were used. We instructed the two players to perform single-leg jump and double-leg jumps a total of three times each. Results The results of this study indicate that YHR and KYN appeared to increase their time or maintain the same time compared to the previous phase and displacement appeared higher when skill success occurred after the double-leg jump. The Shoulder & hip joints of YHR, KYN appeared larger in E2 and the hip joint of KYN appeared to increase in E1. Single-leg jump appeared similar or decreased the performed time of the previous phase in the last P5. YHR appeared larger only at a hip joint angle and KYN appeared smaller at the hip joint. The muscle activity(iEMG) of the two players appeared greater during skill failure than most of the muscles. Conclusions When perfectly performing 109C skills, the acquisition of medals in international competitions is possible. Therefore, in the future, it is necessary to study all of the variables that pertain to 109C.
Purpose The purpose of this study was to apply the Self-Assertiveness Training based on Solution-Focused to student-athletes caused by violence in sports. Methods Participants were five Taekwondo athletes in this study. They were consisted of offenders, a accuser, and a victim. The head coach of the team asked for counseling to resolve the conflict. Data was collected with quantitative, qualitative data, and group dynamics. The group counseling program was conducted for 90 minutes a week for eight weeks. Results The results are as follows. First, (application process) the 8-week Self-Assertiveness Training based on Solution-Focused was assessed to be applied step by step and systematically. Second, (qualitative evaluation) as a result of analyzing the observation journal and the interview data, the participants experienced the change of attitude and thought of group members in a short period of time by focusing on enhancing self-assertiveness. Third, (quantitative evaluation) self-assertiveness and attitude of school violence measured by questionnaires were higher in post-survey than pre-survey. In addition, participants' satisfaction with the program was found to be very positive. Discussions and Suggestions Self-Assertiveness Training based on Solution-Focused was found to have a significant effect on conflict resolution among the student-athletes who have experienced violence in sport. This programs was expected to increase the value of use in the sport field. Based on this case study, We suggested for future research.
Purpose The purpose of this study was to investigate the effects of coupled high frequency rTMS and prism illusion in elderly stroke patients, based on the result of previous studies which discovered the effect of bilateral training, mirror rehabilitation treatment, and rTMS. Methods This is a case study of 4 stroke patients who were homogeneous on the basis of selection criteria such as brain injury area, duration of onset, degree of upper limb movement function. A total of 24 rehabilitation sessions were conducted three times a week during the training period, and TMS(transcranial magnetic stimulator), EMG, motion analysis system, and prism optical glasses were used for apparatus. Results The results of the study were as follows: Combined rehabilitation exercises were found to be beneficial to restore upper limb function in stroke patients. Particularly, the maximum speed of stretching and JTT(Jebsen-taylor Test) performance showed improvement after training. The amount of total map volume and MEP(megnetic evoked potential) increased in evaluation of neurophysiology. Conclusion The upper limb dysfunction of stroke patients could be restored by combine rehabilitation exercises.
Purpose The purpose of this study is to explore ‘K League Influx (KLI)’ which is the phenomenon a number of international footballers migrate to South Korea and its factors. Methods Qualitative case study was conducted with 10 footballers who have migrated to South Korea and 4 their Korean agents. Results The KLI can be explained with four factors such as (1) Asian football dream and K league as a stop (not destination); (2) Brazilian footballer salary increase caused by Chinese football policy; (3) Financial crisis of European football market; and (4) The quantitative and qualitative changes in the agent market due to FIFA’s abolition of agent system and the development of new media. Conclusions These factors are close to the properties of external factor rather than internal factor. It requires various perspectives on sport labor migration (academic significance) and new management philosophy of K league and each club (practical discussion). Therefore, this study examined the possibility of 'selling-league' and suggested the follow-up study and policy direction related to it.
Purpose The purpose of this study is to explore the trend of K league exodus and its factors. Methods Qualitative case study was conducted by selecting 9 footballers and 7 their agents as the participants who have migrated from South Korea to China and the Middle East. Results The factors of migration were categorized as three push and pull factors such as economy (individual income and club's profit), policy (employment for foreign and military service) and environment (markets in home and abroad). To understand sport migration in the economic factor, there should be the environmental condition (overseas market) to pay high salaries and transfer fee to individuals and their clubs, and at the same time, the domestic market should be relatively poor environment. In addition, this study overcame limitations of economic and environmental factors by classifying Asian quota system and military service into political factor, and found the specificity (local context) of K league. Conclusions In conclusion, this study can be regarded as the first empirical work on sport labor migration in Korea and valuable as basic data of follow-up studies.
Purpose This study aims to explore migration factors of Korean male footballers who have moved from South Korea to Southeast Asian countries. Methods Qualitative case study was conducted with 9 footballers, 4 their agents and 2 K-league staffs as the participant. Results As a result, by regarding their migration as involuntary decision, this study could provide academic and practical discussion on sport labor migration. First of all, this study established theoretical framework for involuntary migration of the participants through ‘Push-Pull Theory’ which focuses on demand and supply on the labor force. Second, this study found that a local rule (FA compensation system) of Korean professional football league (K league) and hierarchical collectivist culture contributed to their migration, which has not been reported by previous studies focused on the voluntary migration of mainstream players and it reflected local context of K league. Conclusions In conclusion, this study confirmed that sport labor migration was also considered as social phenomenon and reflected a cross section of a particular society. Through the migration of athletes, we can provide a variety of viewpoint on economic (market) structure, related policy and system in a particular society, and understand migration motives in terms of agency (subculture).
With coming industrial convergence era, there are the necessity of industrial convergence in sport industry. Therefore, the purpose of this study is to provide classification system and trend. This study applied case study method with semi-constructed interview, integrative literature review and observation. In addition, this study provide the conceptual framework for the classification system in sport industry related to industrial convergence. To conclusion, among the several criteria related to industrial convergence for product-new technology criterion, there are virtual sports, diagnosis valuation solution and exercise guide solution for participant sport market. In the case of new technology-service criterion, there are new media and virtual broadcasting for spectator sport market, and u-learning for participant sport market. For product-service criterion, there are complexity of sports facility and sportainment for spectator sport market, and virtual gaming sports and participatory tour for spectator and participant sport market. In addition, the trend of the sport industrial convergence has changed from leading media industry to converging with diverse industry areas.
