Purpose The purpose of this study was to explore cultural meanings of the concept of ‘Che-Yuk-In’ through a critical examination of how it was described, portrayed, and represented in the narratives of the mainstream newspapers in the early days of the nation(1945-1961). Methods As for the data collection and method, a total of 338 articles were collected by searching of "Che-Yuk-In" through the database provided by the Naver News Library. Sorting out them with the point of whether the concept simply denotes the number of players or the majority of athletes, for example, we select 140 column-type articles and analyzed how it serves as a linguistic element and what discourses were involved in the narratives. Results Our argument is twofold: 1) the concept of ‘Che-Yuk-In’ is a kind of self-representative terminology with which a particular group of people, who call themselves ‘Che-Yuk-In’, construct their collective identity into a particular type of the idealized subject, so-called sporting citizen, and 2) this construction consists of two functions: one is to share the emotion of pride by celebrating success and achievements of the sporting figures, and the other is to collectively reflect shame by criticizing negative incidents and controversies such as corruption, factional disputes, violent behaviors, which broke in the sporting practices. Conclusions With a brief summary, this paper concludes with some suggestions for future studies, in terms of how the shameful past should be embraced within the field of Korean sport history, and why a conceptual history of the ‘Che-Yuk-In’ might need to be further expanded.
Purpose The purpose of this study was to investigate the effects of aerobic exercise intensity on body composition, health related fitness, and quality of life in elderly women. Methods 48 elderly women over 65 years of age without physical and mental problems were assigned to four groups: control group, low intensity, moderate intensity, and high intensity aerobic training group. The aerobic exercise group applied a heart rate reserve (HRR) to low-intensity group (HRR 40-55%), moderate intensity group (HRR 55-70%), high intensity group (HRR> 70%) for 12 weeks, 3 times a week for 20 minutes a day. Subjects of the control group were to maintain their usual lifestyles during the same intervention period. Body composition, health related fitness, and quality of life were measured and analyzed using repeated two-way ANOVA. Results The main results obtained in this study are as follows. 1) There was a significant decrease in sitting forward bending in the low intensity group and a significant increase in EQ-VAS. 2) There was a significant decrease in body weight, BMI, and 6 minutes walking in the moderate intensity group, and a significant increase in grip strength and EQ-VAS. 3) The high intensity group showed a significant decrease in weight, BMI, waist circumference, sitting forward bending, and 6 minutes walking, and a significant increase in grip strength, sit and stand, functional reach, and VO2max. On the other hand, there was no significant change in all variables in the control group. Conclusions In conclusion, aerobic training was found to be effective for body composition, health related fitness and quality of life in elderly women. In particular, it can be concluded that high intensity aerobic training is effective for health related fitness, and low and moderate intensity aerobic exercise is effective for improving quality of life.
The purpose of this study was to critically interpret a certain sports-related idea, "Integrated Korean Team," which was an issue at the PyeongChang Winter Olympics. The idea emerges as a specific political agenda under the conditions of domestic politics and the special environment of Korean national affairs and discourse. To this end, we investigated media texts on the relationship between sports, political dynamics and views on related discourse that were produced in 1990-1991 and 2018. The main findings are as follows: First, sports functions as a political socialization tool for political power as it forms public opinion. Second, sports exchanges work as a kind of international politics. Specifically, political power controls sports as certain political situations arise and political elites' needs change. Third, mega sports events have tended to become politicized in recent years as they become more effective. Fourth, North Korea’s sports under political power cannot be easily dealt with by the private sector, and it has limitations because it is not politically independent. The analysis showed that the negotiation process and realization of the Integrated North and South Korean Team seemed to be a turning point in politics and sports. Here are the conclusions drawn from discussing the two unifying events in 1991 and the situation in 2018. First, both South and North Korea pulled the Integrated Korean Team card when political needs arose. Second, when the two Koreas did not need to reconcile due to changes in the political situation between the two Koreas, they did not want to make efforts to integrate Korean Team. Third, the position of the political elite was directly represented by the position of the South-North Korean team. Fourth, the supporting public opinions of the Integrated Korean Team are gradually diminishing as the power gap between the two Koreas widens and sports players' human rights issues emerge.
[Purpose] This study aimed to examine the effects of complex physical training on exercise and football performances in youth football players. [Methods] The subjects (n=16) were randomly assigned to either a complex physical training group (CPG, n=8) or a control group (CON, n=8). CPG was performed the complex physical training for 50 minute per day, and 2∼3 times per week, for 8 weeks. Exercise performance (health related physical fitness, skill related physical fitness, Y-balance and functional movement screen; FMS) and football performance (juggling, speed dribbling, shot passing, long kick and triple hop) were measured before and after 8 weeks complex physical training. [Results] Sit-up (p=0.002), sit and reach (p=0.040), 50-m run (p=0.031), side step (p=0.005), single-leg standing with eyes closed (p=0.040), plank (p=0.023), dominant composite score (p=0.002) and non-dominant composite score (p=0.005), deep squat (p=0.009), inline lunge (p=0.042), active straight leg-raise (p=0.015), rotary stability (p=0.049), total score(p=0.001), speed dribbling (p=0.030), dominant triple hop (p=0.001) and non-dominant triple hop (p=0.032) were statistical significant interactions between group and time. [Conclusion] Our findings indicate that complex physical training has beneficial effects on performance improvement of exercise and football in youth football players.

The differences among the specific sub-factors of behavioral skills factors was the highest in crossing catching to be followed by cross punching. And goalkeepers of K-League were higher than those of the national team. In back pass kick factor in kick factor and build-up factor in strategy factor, goalkeepers of the national team were higher than those of K-League. In kick factor, there were significant differences in goal kick (out of play), back pass kick (in play), cross punching, and build-up factors. Second, as for behavioral skills factors of goalkeeper according to the result of match, there were significant differences in catching factor, punching factor, and strategy factor; there were no significant differences in ground kick factor among kick factors; there were significant differences in factors of goal kick, volley kick, and free kick.
It has been known that β-alanine supplementation induce the increment of carnosine in vivo and was effective in delaying fatigue by buffering the hydrogen which was formed during exercise. This study was designed to investigate the effects of 4 weeks of β-alanine supplementation on physical fitness and blood lactate concentration in middle school soccer players. Nineteen middle school soccer players were randomly assigned to either one of two groups, i.e., β-alanine group (n=10) and placebo group (n=9). Subjects in β-alanine group consumed β-alanine 2 g/day during 1st and 2nd week, as well as 3 g/day during 3rd and 4th week, whereas subjects in placebo group consumed maltodextrin in the same manner. All subjects ate same menu and trained same amount at the same training camp during the intervention period. Body composition, aerobic capacity, anaerobic capacity, isokinetic function, and blood lactate concentration during maximal GXT were measured at pre- and post-test. Main results of the present test were as follows: 1) Fat mass and percent body fat decreased significantly in β-alanine group. 2) No significant changes were found in variables related to aerobic capacity in both groups. 3) Average power increased significantly in β-alanine group. 4) Isokinetic muscular endurance increased significantly in β-alanine group. 5) Blood lactate concentration did not change in eithet group; however, blood lactate concentration immediately after maximal GXT in β-alanine group tended to be increased more than placebo group. It was concluded that β-alanine supplementation would have positive effects for improvement of body composition, anaerobic capacity, and muscular endurance in middle school soccer players.
Purpose Soccer-related social media BigData includes complex information related to soccer players and is continuously and instantly generated. Text mining research is actively carried out for this kind of social media contents analysis, but it tends to be analyzed with limited linguistic characteristics such as understanding of language complexity and context, ambiguous terms, rhetoric, and new terms. This can be attributed to the fact that the tools commonly used for text mining use universal terminology dictionaries and packages that exclude the peculiarities of the analysis themes. The purpose of this study is to develop an Ontology model, which are representative tools for defining semantic ambiguity and relationships and systems between terms of text data. Methods In order to achieve the research objectives, we applied the 7-step development method of ‘Ontology Development 101: A Guide to Creating Your First Ontology’, which is useful for ontology development. Each step includes 1) Determine the domain and scope of the ontology 2) Consider reusing existing ontology 3) Enumerate important terms in the ontology 4) Define the classes and the class hierarchy 5) Define the properties of classes-slots 6) Define the facts of the slots 7) Create instances. In particular, the 3rd-step of this study, the glossary stage, is to extract core terms that make up he ontology, but since the goal of this study is to develop the ontology that can be used in social media contents analysis of soccer players, we conducted a social media text analysis related to actual soccer players and selected 484 core terms. Results The ontology which was developed in this research for social media contents analysis of soccer players consisted largely of four parts(General terms, performance results terms, common terms, and Characteristic term) and classified according to the content characteristics of the term. Conclusion Developed ontology in this study is object-oriented that defining classes and objects to define divisions and relationships between terms and also means a social media contents knowledge system of soccer players. In addition, it performs a function as a secondary tool which can be utilized for atypical data analysis.
Purpose The purpose of this study was to find out the physical characteristics of Wushu athletes by comparing the differences on the results of physical fitness between the male athletes of the Wushu national team Taolu and the Sanda group. Methods Measurement of basic and professional fitness based on muscle function, targeting 37 men Wushu national team players (24 taolu, 13 Sanda) in the selection and evaluation contests twice in 2018 and 2019. Body composition, isometric muscle strength, flexibility and equilibrium, anaerobic power, and isokinetic muscle strength. The fitness factors were divided into two groups, Taolu and Sanda. Results First, body fat rate of the Sanda athlete group was significantly lower than that of the taolu athlete group (p<.01). Second, in the isometric muscle strength category(back muscle strength, grip strength), the Sanda athlete group had higher muscle strength than Taolu athlete group, but there was a statistically significant difference only in the left grip strength (p<.01). Third, in terms of flexibility and equilibrium, the taolu players were significantly higher in all items(p<.001). Fourth, in the anaerobic power, the taolu athlete group had higher both the peak power and the mean power, and there were a significant differences(peak power: p<.01, mean power: p<.001). Fifth, isokinetic muscle strength was significantly higher in the right knee flexion of the taolu athlete group (p<.01), and lumbar extensor muscle was significantly higher in the Sanda athlete group (p<.05). Sixth, in the isokinetic strength ratio, the knee flexion ratio of the Sanda athlete group were significantly higher on the left and right knee flexion and extensor ratios (p<.05). In addition, in the lumbar flexor and extensor ratios, the group of Sanda athlete group were significantly higher on the lumbar extensor(p<.05). Seventh, there was no significant difference between two groups in isokinetic muscle power. Conclusions The results of this study can be used as basic data to improve the efficiency of technical and physical training through the analysis of the characteristics of Taolu and Sanda. The effectiveness of this training will help to improve the performance.
The purpose of this research was to investigate the difference in decision making and perceived eye-focus location on peripheral vision and attacker's expertise in basketball tactical game. A total of twenty four subjects who were expert guard players (n=8), expert basketball center players (n=8), and novices (n=8), participated in this experiment. All subjects participated two tasks. The first task was to anticipate the attack direction after viewing a sequence of basketball tactic film. These films simulated three situations including offensive patterns. The three situations were consist of 3, 6, 9 degree peripheral vision. The second task was to express the level of confidence on their anticipation and to verbalize the perceived visual cues immediately after responding. For this research, an Eyelink eye movement system, an equipment for measuring anticipating, basketball tactic film were used. The variables on anticipation of attack direction were speed, accuracy, and the level of confidence. The acquiring process of advanced visual cues was examined through analyzing visual search strategies and perceived eye-focus location. In order to examine the difference in visual search, in decision making, and in perceived eye-focus locations as a function of expertise, data were analyzed through descriptive statistics, two-way ANOVA, and two-way MANOVA. This research had the following results. First, there was a significant difference on the search rate among the three groups. But, on the other hand, expert guard and center exhibited more fixations of shorter duration than the novices in the 6 and 9 degree condition. Second, results from the ratio of fixation time allotted to areas in the 3 degree condition revealed that experts spent more time fixating the ball-attacker(BA) than novices. The results from the ratio of fixation time allotted to areas in the 6 and 9 degree condition revealed that expert guard and center spent more time fixating the non-ball attacker(NBA) than novices. Expert guard also fixated longer on the pass attacker(PA) and meaning space(MS) than novices. Finally, experts paid attention to two or three locations simultaneously, whereas novices did to only one location such as the ball, attacker, defender, non-meaning space in all condition.
