This research aims to establish the effects of the team cohesiveness of the players on the team effectiveness according to the handball coaches’ leadership types. To achieve this purpose, a questionnaire survey was conducted on 420 handball players and the data were collected using the questionnaires of leadership, team cohesiveness, and team effectiveness, and were analyzed through applying the statistical program, and the following conclusion was obtained. First, the handball coaches’ transformational leadership had positive effects on the team cohesiveness. Second, the handball coaches’ transactional leadership had positive effects on the team cohesiveness. Third, the handball coaches’ servant leadership had positive effects on the team cohesiveness. Fourth, the handball players’ team cohesiveness had positive effects on the team effectiveness. Fifth, in the effects of the handball coaches’ leadership on the team effectiveness, the team cohesiveness had indirect effects. In other words, the conclusion that the servant leadership in the handball coaches’ leadership types had a relatively greater influence on the team cohesiveness through the team effectiveness was obtained, so the final conclusion that the handball coaches’ morality, fairness, and trust in coaching activities are important was obtained.

Purpose: The purpose of this prospective study is to compare the results of arthroscopic reconstruction of ACL using autologous hamstring tendon (Group 1) and autologous bone patella tendon bone (Group 2). Materials and Methods: From Jan. 2004 to Dec. 2007, fifty patients were analyzed in this study. A single surgeon performed the ACL reconstruction with autologous hamstring tendon (25 patients) and autologous bone patella tendon bone (25 patients) alternatively each other. The mean follow up period of two groups was 38 months (range 25~58 months). We evaluated the result of Lachman test, Pivot shift test as a physical examination and Lysholm score, Tagner activity scale as patients' satisfaction and functional status and Telometer for anterior instability of each groups at the time of final follow up. Results: In final results, negative or mild positive findings on Lachman test were 24 out of 25 cases (equally) in each groups.) Twenty two cases in the Group 1 and 21 cases in the Group 2 were negative on Pivot shift test. Lysholm scores mark 94.6 points in group 1 and 92.3 points in group 2 at the final follow up and Tegner activity scales mark 8.5 points (Group 1) and 8.1 points (Group 2) at the time of last follow up and there were no differences between the two groups statistically. The numbers of patients who have less than 5 mm of anterior translation of tibia under telometer at 20 degrees of knee flexion are 24 cases in group 1 and 23 cases in group 2. Conclusion: The overall improvements of clinical scores (Lysholm scores and Tegner Activity scales) of the group 1 were a little bit superior to those of the group 2, but there were no significant statistical difference between two groups.

In making an attempt to examine the fitness training effects on coordination and strength of preschool children, four groups of 5 year old children consisted of two experimental groups of three children for each sex and two controls of similar composition were employed. Experimental groups were subjected to one circuit of various physical activities which lasted for 30-40 minutes per day for 5 weeks. Measurements obtained in continuous tapping, whole body reaction time, grip strength and vertical jumping during those five weeks except in Sundays and national holidays were analysis method and were compared with the results of physical fitness tests. The results were summarized as follows: (1) The analysis of daily fluctuations in physical fitness test performances for five weeks showed that each subject had specific pattern of fluctuations in terms of different periods, amplitudes and linear trend. (2) When compared the mean amplitudes of daily fluctuations in physical fitness tests with the mean values of increase from pre-training values, tapping was found to be the only variable with significant differences between them.

Factors Affecting the Extent of Graft Tendon Synovialization after Double-Bundle Anterior Cruciate Ligament Reconstruction: Based on Second-Look Arthroscopic Findings

Background: We aimed to examine the factors that influence synovialization of the grafted tendon after double-bundle anterior cruciate ligament (ACL) reconstruction based on second-look arthroscopic findings. Methods: Out of 205 knees that were treated between August 2008 and May 2016 with double-bundle ACL reconstruction using bio-absorbable cross-pins and Endobuttons for femoral tunnel fixation, we enrolled 65 knees (64 patients) that underwent secondlook arthroscopy with hardware removal at 1 year postoperatively. Measured clinical outcomes included the Lysholm score and Tegner activity score that were evaluated preoperatively and during the final follow-up. We analyzed the relationship between synovial coverage and patient age, length of the preserved remnant tissue on the tibial side, type of bundle (anteromedial or posterolateral), type of graft (autograft or allograft), and time from injury to surgery. Results: The area of synovial coverage showed a significant statistical correlation with patient age and the length of the preserved remnant tissue on the tibial side. The average synovial coverage was significantly better for the anteromedial bundle than for the posterolateral bundle, better for the autograft than for the allograft reconstruction, and better when treated in the acute stage than in the chronic stage. However, synovialization of grafted tendon did not correlate to clinical outcomes. Conclusions: While we were able to identify several factors influencing synovialization of the grafted tendon after double-bundle ACL reconstruction, including patient age, length of preserved remnant tissue of the torn ACL, type of bundle, type of graft, and time from injury to surgery, we found no evidence that increased synovialization improves clinical outcomes at 1 year postoperatively.

This study was designed to investigate a minimum sample size requiring to identify characteristics of various variables in potentially implicated social phenomenon in accordance with the purpose of many studies on leadership of psychological tests. So, based on the multidimensional model of Chelladurai(1978), The basic hypothesis of this study was established after ascertaining the behavioral scales of sports leadership developed by Chelladurai& Saleh(1980) as presuppositionally validated theoritical model. This model identifies whether the stability of factorial structure through monte carlo simulation was ifluenced or not by variables in gender and sport types(team game and individual game). Conclusion obtained from the result of this study was as followed : after excluding factor 5 reducing internal agreement of completed model consisted of reversed items in previous study as well study on gender and sport types, it appear that testified factorial score of reduced model was stable rather than total factorial structure of questionare. Also, in the result of mainly analyzed model index according to sample size, full model and reduced model was some different but both models was more suitable as the number of case was increased, but this study show that some problems must basically be testified in the future. The number of cases. In gender and sport types, the number of cases was lack on parameters of population and representation of samples in team sport and women. Also, First, this study was accomplished to test whether how many the number of case was necessary to identify elit athelets or not. second, a limited item contents in this study was firstly assumed to ascertained circumstance of population and limit items as 40. a minimum sample size for this study has some closing relationship on the number of parameters assumed. Also, this study was additionally necessary to perform investigation on sample size and the number of items to ascertain reliability.
