PURPOSE Recently, the need to improve service quality to provide an ideal viewing experience for sport OTT service users has increased. This study aimed to analyze user reviews of the SPOTV Now app, an OTT service specializing in sports in South Korea, to identify major perceptions of viewers and suggest measures for improvement. METHODS Review data (8,512) recorded on the SPOTV Now app were collected from November 21, 2017 to November 30, 2023. LDA-based topic modeling analysis was conducted along with a series of data preprocessing processes. Sentiment analysis was carried out through machine learning logistic regression analysis and odds ratio scores were calculated. RESULTS A total of five topics were derived, including ‘member management service', 'service stability', 'sport streaming service', 'sport video service', and 'subscription service'. Sentiment analysis indicated that 'exclusive', 'server', 'payment', 'log-in', 'authentication', 'pay', 'subscription', 'advertisement', 'play', and 'loading' were the top ten keywords. CONCLUSIONS Sport OTT operators should be more responsive to user requests and feedback, and video playback and server error problems should be improved for service stability. It is necessary to secure diversity as well as exclusivity of content, in addition to minimizing advertising or preparing various rate types, so that app users feel that they receive high value for their money.
PURPOSE Taekwon gymnastics is expected to be a program that can overcome the management difficulties currently faced by Taekwondo gyms and contribute to the expansion of Taekwondo base. Therefore, this study aimed to examine the relationship among organizational identification, flow experience, intention to continue participation, and recommendation intention of Taekwon gymnastics participants. METHODS In this study, data was collected from 313 teenagers participating in Taekwon gymnastics at Taekwondo gyms in the metropolitan area from September 10 to 24, 2021. A total of 267 questionnaires were selected as the final sample, and data analysis was conducted using SPSS 23.0 and AMOS 23.0. RESULTS Organizational identification had a significant effect on flow experience, challenge only had a positive effect on intention to continue participation, flow experience did not significantly affect recommendation intention, and intention to continue participation had a significant effect on recommendation intention. CONCLUSIONS The results of this study confirmed that organizational identification can contribute to improving inner pleasure and self-esteem, and it is necessary to examine the role of factors that can mediate the relationship between flow experience and behavioral intention in the future. Furthermore, managers of Taekwondo gyms should hold various events that can inspire teenagers’ sense of challenge to encourage intention to continue participation.
PURPOSE Previous research has rarely examined foot segment motion and muscle activity simultaneously in relation to foot type. Therefore, this study aimed to investigate how foot type influences segmental foot kinematics and lower limb biomechanics during walking. METHODS Fifty-eight healthy adults were sorted into normal group (NG), pes planus group (PPG), or pes cavus group (PCG) using the Foot Posture Index, navicular drop, normalized navicular height, and normalized instep height. Furthermore, three-dimensional foot kinematics and lower limb muscle activity were recorded during 12-meter, self-paced walking using an optical motion capture system and surface electromyography. Kinematic analysis during the stance phase included measurement of joint angles and ranges of motion (ROM) for the following segments: foot relative to the shank, forefoot relative to the midfoot, lateral forefoot relative to the midfoot, medial forefoot relative to the midfoot, and hallux relative to the medial forefoot. Moreover, muscle activity analysis included the tibialis anterior, peroneus longus, and medial and lateral heads of the gastrocnemius. RESULTS Compared with the NG and PPG, the PCG exhibited greater ROMs in the frontal plane for the forefoot relative to the midfoot and medial forefoot relative to the midfoot. Additionally, the PPG exhibited a greater ROM in the frontal plane for the hallux relative to the medial forefoot compared with the NG. The intersegmental angles according to foot type demonstrated distinct kinematic differences between the PPG and NG in the transverse plane, specifically in the forefoot relative to the midfoot and medial forefoot relative to the midfoot relationships. However, no significant differences were observed in lower limb muscle activity during the stance phase. CONCLUSIONS This study provides insights into kinematic changes according to foot type during walking. Moreover, the findings of this study may deepen our understanding of the intrinsic risk factors for lower extremity injuries and tissue stress associated with variations in foot type.
PURPOSE Recently, local governments have demonstrated an increased interest in sports cities to strategically ensure sustainable urban competitiveness, revitalize the local economy, and improve residents’ quality of life. Therefore, this study identifies key factors and their priorities for building a sustainable sports city image in noncapital local governments based on city branding and local governance theories. METHODS Data were collected from a panel of 15 experts in sports cities using modified Delphi method and the analytic hierarchy process and analyzed using SPSS 23.0, Excel, and the cloud-based research automation platform SSRA, obtaining means, standard deviations, content validity ratios, interquartile ranges, stability, convergence, consensus, and consistency ratios. RESULTS The Delphi survey produced 6 key factors and 27 items. The key factors, according to relative importance, were as follows: “securing adequate financial resource,” “support from local government,” “revitalization of community-based sports activities,” “establishment governance among stakeholders,” “efforts toward sports city branding,” and “promotion of sports industry.” For each factor, important items were “mayoral interest and commitment,” “building cooperative networks with sport federations, local sports associations, and education offices,” “sufficient budgetary support from the local government,” “development of sports infrastructure,” “attracting professional sports teams,” and “designation and development of locally specialized sports.” CONCLUSIONS Local governments should first establish structural foundations by securing sufficient budgets and providing administrative support, among other tasks, as a starting point for designing sports city policies. When branding strategies that systematically strengthen a sports city’s identity and symbolism are organically linked based on these structural conditions, the effectiveness and sustainability of sports city policies can be further enhanced.
