Abstract

This study has analyzed 33 domestic games and 26 overseas games by targeting women curling teams of home and abroad, and looked into what main performance variables are, how level differences of domestic team appear, and from which variables differences between winning team and defeated team come out in overseas teams. Also, main strategies has been suggested that are used most commonly for kick-off offense and latter offense, blank strategy in order to prepare countermeasures, and digital media DB has been constructed that can utilize proper countermeasures easily and simply, and a model has been proposed for predicting victory/defeat. To accomplish such goal, a variance analysis has been carried out by dividing domestic teams into each level after calculating frequency and ratio with SPSS18.0, and t-test analysis has been carried out by overseas teams. Also, the accuracy of victory/defeat classifications has been suggested by using an artificial neural networks method. As a result, a lot of technical proficiency differences have appeared among Class A(upper rank), Class B(middle rank), and Class C(lower rank) in domestic teams. The ‘Guard’ which is an aggressive variable has turned out to be used more in upper and middle teams than in lower team, and the ‘Tab Back’ has been used more in upper rank than in lower rank. Furthermore, regarding the average comparison on victory/defeat in international games, victory teams have more significant difference(p<.05) than defeated teams in accuracy of shot techniques and strategy accomplishing abilities, and victory teams have been turned out to use less ‘Drew’ and more ‘Take’ than defeated teams significantly in Drew and Take’ technique variable. Finally, the accuracy of a prediction model has been 91.7% for learning and 92.9% for the test result to predict the victory/defeat in international games through the artificial neutral network analysis. The prediction accuracy of domestic games was 81.0% for learning and 71.4% for the test.

Abstract

The current study aimed to investigate the impact of SERVQUAL on sport consumer behaviors using meta-analytic techniques. Findings from 25 dissertations and 26 journal articles were used to test of a model of the SERVQUAL on various sport consumer behaviors via the comprehensive meta analysis (CMA) program. Results showed that SERVQUAL has a large effect on sport consumer behaviors, with a fixed effect size of .383. In terms of the relative importance of the SERVQUAL sub-factors, sport consumer behaviors were influenced most by empathy, followed by reliability and tangibles. In predicting sport consumer behaviors, SERVQUAL had a most positive effect on, in order of, loyalty, customer orientation, and commitment. Results also found significant moderating evidence for sport facility types, publication types, publication year, the ratio of male and respondents' age.

Abstract

This article aims to examine the research trend of sport history by analysing published research articles over the last decade in the Korean Journal of History for Physical Education, and suggest directions of research in sport history based on the results. We have reviewed a total of 264 articles relying on the analytic framework including the criteria of time period, method, nation, theme/topic, and purpose. The research findings are as follows. First, the post-Liberation period has been studied most often with 45.3%, followed by the Japanese Colonization period (20.2%), the Joseon Dynasty period (11.4%), the diachronic research (8.8%), the period from ancient times through Goryeo (8.1%), and the period of Enlightenment (6.2%). The results indicate that most recent studies in the journal unilaterally focus on the Modern and Contemporary history with 71.7%. According to the analysis result by research method, second, more than 90% of the studies have been conducted using qualitative methods while only 0.6% of the papers have adopted quantitative methods. The qualitative methods include textual analysis, participant observation, oral life story, and focus group interview. Textual analysis has been used most often with 74.5%. Oral life story has been second (22.5%), followed by participant observation (2.1%) and focus group interview (0.3%). The findings from this category show that it is still necessary to diversify research methods and vitalize interdisciplinary research. Third, in terms of nation, over 70% of the papers have studied about Korea, and European countries are the second most frequent region in the research trend (8.3%). The nation that follows is China with 6.4%. Although we analysed a Korean journal in sport history, the result exposes the lack of scholarly attention in the studies of sport history to world sport history reflecting comparative perspectives. By the criteria of theme/topic, fourth, genre has been studied most often with 31.7%, followed by figure (14.1%), facility/institution/organization (14.0%), system/policy/event (12.8%), philosophy/ideology/theory (6.7%), remains/relics/documentary material (6.3%), and domestic regions (5.4%). The results show that the recently published research articles have attempted to include a variety of genres in sports, play, and dance. While the topics for figure and facility/institution/organization also receive significant interest, it is limited that the studies mostly focus on male sport figures but female figures are barely explored. Even when female figures are researched, the attempts are observed only in the studies of dance. Fifth, the largest ratio of papers has had the research purpose of historical evolution (37.6%), followed by value/significance (20%), type/characteristic (15.5%), thoughts/ideology/theory (9.1%), origin (6.6%), suggestion/proposal/prediction (5%), comparison/correlation (5%), and concept/terminology (1.2%). The results expose that the studies tend to concentrate on historical evolution relying on chronological description while the research on concept/terminology is of little scholarly interest. Based on what we have found, it is identified that the recent studies in sport history have mostly focused on the historical evolution of a specific sport genre in the Korean Modern and Contemporary history using textual analysis. Consequently, the results suggest that researchers in sport studies need to put in additional effort to expand research topics and methods, and invite comparative perspectives involving inter/cross-national studies.
