ジャーナル フリーThe purpose of this study is to look at the decisions on yuko-datotsu being made through the system of "Claim for Judgment Using VTR" that the Korea Business Kumdo Federation (KBKF) has introduced. This thesis is organized as follows:
·Details leading up to the introduction of "Claim for Judgment Using VTR".
·Clarification of its regulations and subsidiary.
·Analysis of the assessment of decisions made using a video tape recorder (VTR).
·The relation between decisions made using the VTR and the requirements of yuko-datotsu.
The results obtained were as follow:
1.Before the introduction of the "Claim for Judgment Using VTR," systems using 5 referees and 4 referees were investigated.
2.The system of "Claim for Judgment Using VTR" was accepted by all concerned.
3.In case kantoku has a doubt about the yuko-datotsu, kantoku may file igi with shinpan-shunin in this system.
4.Judges check the datotsu-bui of the opponent’s kendo-gu or datotsubu with shinai using the VTR. This method bears some parallels to the instant replay system that many professional sports have adopted.
5.But if they move to checking not only datotsubu or datotsu-bui, but also checking the yuko-datotsu, the requirement of yuko-datotsu will be changed by the introduction of this system.抄録全体を表示PDF形式でダウンロード (928K) -

ジャーナル フリーTwo types of floor surfaces are used in kendo gymnasiums (kendo-jyo). The first is a polyurethane resin
(PR), and the other is non-coated wood (NC). The present study aimed to investigate the relationship of floor surface to sports injuries and subjective evaluations of the influence of floor surface on performance in kendo. Subjects were 626 members of kendo clubs at thirteen universities. Furthermore, the relationship between sports injuries and the use of protective equipment was explored by multi-correspondence analysis (MCA). Subjective evaluations of floor surface on performance were subjected to factor analysis. Moreover, to investigate the relationship of floor surface to sports injuries and subjective evaluation of the influence of the floor surface on performance, logistic analysis was conducted and odds ratios (OR) were calculated. According to structural relationship identified by MCA, the use of protective equipment was found to be associated with sports injury, but not for. From the subjective evaluations of floor surfaces, the following three factors were extracted: "slip, spring and burden on the body," "thermal sensation when hot or cold and endurance for wet," and "slip and endurance for dry." In the PR group, subjects reported training for a short time (OR=.240), and many experienced pain in the Achilles’ tendon (OR=2.238). In evaluations of floor surfaces, NC was considered to have better "spring," "humid," and "impact on the sole of the foot," but PR was considered to have better "bracing in shooting for striking" and "dryness." When selecting PR or NC as the floor surface in kendo-jyo, it is most important to consider each surface’s burden on the body and influence on performance in kendo.抄録全体を表示PDF形式でダウンロード (529K) -

ジャーナル フリーThe purpose of this research is to make a quantitative analysis of iaido (the martial art of using the Japanese sword) proficiency using body movement data captured with a motion capture system. We carried out motion capture experiments on kirioroshi (a straight overhead slash) movement of roppon-me (a two-handed sword thrust) in iaido. It proved possible to analyze the proficiency of an iaido practitioner by conducting a principal components analysis (PCA) and a cluster analysis using the characteristic parameters of body movement. As a result, we verified that a skilled practitioner has more velocity with respect to center of gravity and right-hand movement, and has a more stabilized body than a beginner when performing kirioroshi. Therefore, it was found that the feature values extracted from a PCA can be used to classify the proficiency of an iaido practitioner by using cluster analysis.抄録全体を表示PDF形式でダウンロード (733K)

ジャーナル フリーIn this research, we devise kata (or a set of forms), which includes basic throws, as a teaching material for a judo class in junior high school in order to teach judo effectively and safely.
The kata we devised consists of three sets, and each set comprises three throws:
First set-1 Hiza-guruma 2 Sasae-tsurikomi-ashi 3 O-goshi
Second set-1 Kouchi-gari, 2 Tai-otoshi, 3 Osoto-gari
Third set-1 Ouchi-gari, 2 Tsurikomi-goshi, 3 Seoi-nage
In the kata, right-hand kumikata and right-side throws are used, and the kata sets are taught in numerical order from the first set to the third set. The throws in the kata are arranged according to the difficulty of the throws, the ease of the breakfall techniques, and the curriculum guideline issued by the Ministry of Education, Culture, Sports, Science, and Technology. However, how to arrange the throws in the kata, how to move (tai sabaki: body-management) when throwing and getting thrown are one of illustrations and should be further improved.抄録全体を表示PDF形式でダウンロード (457K)

ジャーナル フリーThe purpose of this study is to examine how Korean youths perceive kendo. For this research we made a comparative study of male and female youths. The subjects of this study were 2,026 Korean youths. Of them, 1,010 were male and 1,016 were female. The average age of the males was 20.8 ± 5.14 ( ±SD ) years and that of the females was 19.6 ± 3.21 years. The results of the study are as follows:
1) Male Korean youths are inclined to perceive kendo as a martial art. They consider kendo to be helpful for practicing courtesy, posture and self-control, but they put little value on kendo for the formation of internal qualities such as sincerity, reliability and humanity. Although their interest in kendo is high, the percentage of those giving up the practice of kendo after a while is higher than that of female practitioners. The cause for this seems to be their greater interest in other sports and cultural activities.
2) Female Korean youths perceive kendo as a sport. In particular, they consider kendo to be an effective activity for correcting one’s posture. They are fascinated by a cultural environment in which young or old, male or female can evenly compete with one another. Because of a prejudicial view that one can easily be injured in practicing kendo and that kendo is very difficult to practice fewer females take it up. But after starting kendo, the percentage of females who stay with it is higher than that of males. Females have a more positive view of the traditional understanding of kendo than males.
Today in kendo classes there is no time given to the cultural characteristics of kendo. But as Korean youths show a high interest in such aspects, there is a need to include the history and traditional values of kendo in kendo classes.抄録全体を表示PDF形式でダウンロード (520K)
