Objective: The purpose of this study was to investigate the difference in muscle strength, kinematics, and kinetics between injured and non-injured sides of the leg after Achilles Tendon Rupture surgery during walking and running. Method: The subjects (n=11; age = 30.63 ± 5.69 yrs; height = 172.00 ± 4.47 cm; mass = 77.00 ± 11.34 kg; time lapse from surgery = 29.81 ± 10.27 months) who experienced Achilles Tendon Rupture (ATR) surgery participated in this study. The walking and running trials were collected using infrared cameras (Oqus 300, Qualisys, Sweden, 100 Hz) on instrumented treadmill (Bertec, U.S.A., 1,000 Hz) and analyzed by using QTM (Qualisys Track Manager Ver. 2.15; Qualisys, U.S.A). The measured data were processed using Visual 3D (C-motion Inc., U.S.A.). The cutoff frequencies were set as 6 Hz and 12 Hz for walking and running kinematics respectively, while 100 Hz was used for force plate data. Results: In ATR group, muscle strength there were no difference between affected and unaffected sides (p> .05). In kinematic analysis, subjects showed greater ROM of knee joint flexion-extension in affected side compared to that of unaffected side during walking while smaller ROM of ankle dorsi-plantar and peak knee flexion were observed during running (p< .05). In kinetic analysis, subjects showed lower knee extension moment (running at 2.2 m/s) and positive ankle plantar-flexion power (running at 2.2 m/s, 3.3 m/s) in affected side compared to that of unaffected side (p< .05). This lower positive ankle joint power during a propulsive phase of running is related to slower ankle joint velocity in affected side of the subjects (p< .05). Conclusion: This study aimed to investigate the functional evaluation of the individuals after Achilles tendon rupture surgery through biomechanical analysis during walking and running trials. Based on the findings, greater reduction in dynamic joint function (i.e. lower positive ankle joint power) was found in the affected side of the leg compared to the unaffected side during running while there were no meaningful differences in ankle muscle strength and walking biomechanics. Therefore, before returning to daily life and sports activities, biomechanical analysis using more dynamic movements such as running and jumping trials followed by current clinical evaluations would be helpful in preventing Achilles tendon re-rupture or secondary injury.

Expanding upon Zhang and Kim's (2013) study involving Chinese consumers, this study investigated key factors that influence U.S. consumers' attitude towards purchasing luxury fashion goods and purchase intent and examined what similarities and differences exist between the two consumer groups in relation to the key factors. A total of 414 respondents completed the online survey questionnaire. Structural Equation Modeling was utilized to analyze data. Brand consciousness, materialism, fashion innovativeness, and fashion involvement were significant factors that affect U.S. consumers' attitude towards luxury fashion goods. Overall, the findings of the current study were greatly inconsistent with Zhang and Kim's Chinese study. The inconsistency provides vital implications to luxury fashion retailers by showing that one size does not fit all and one strategy does not fit all markets.

본 논문은 스포츠 산업은 미국에서 지난 수 십년 동안 계속해서 발전해오고 있으며, 그것은 전문가들에게 있어서 후원자의 수를 증가시키는 주요한 원인이 되고 있다. 이 기회를 스포츠 관련 기관에게 있어서 최고의 이익으로 전환시키기 위하여, 전문가들이 당면한 과제는 스포츠 활동에의 적극적 참여를 유도하는 것과 재방문(지속적 참여) 요소를 홍보하는 것이다. 지금까지 많은 연구들은 스포츠 활동의 참여 정도에 영향을 미치는 변수들을 확인하려고 노력하였다. 하지만 변수들 중 많은 부분은 스포츠의 본질성과 불확실한 장소로부터 파생 되는 우연성으로 인하여 다소 통제하기가 힘든 특징을 가지고 있다. 그러므로 경쟁력 확보와 수익의 극대화를 위하여 관리자들이 통제 가능한 요소를 찾아내고 이해하기 위한 노력이 필수적이다. 이 연구는 스포츠 활동의 참여에 영향을 미치는 통제 가능한 많은 변수들이 1992년 이후 환대산업에 널리 쓰여진 '서비스 스케이프'요소와 일치한다는 것을 알아냈다. '서비스 스케이프'의 개념적 모형에 비추어 보았을 때, 이 연구는 스포츠 활동 참여를 증가시킬 수 있는 통제 가능한 변수들을 분리시키는 시도이기도 하다. 스포츠 산업의 개념으로서 '서비스 스케이프'의 적용을 증진시키는 점에서 뿐만 아니라 더 나아가 이 변수들을 증명하고 변수들간의 관계를 측정하고, 그리고 스포츠 참여의 영향력을 평가하는 미래에 있을 실증적 연구에 대한 의견을 제공하는 점에서 이 연구는 중요하다고 할 수 있다.

The purpose of this study was to comparatively analyze the kinematic variables between the squash backhand and racquetball backhand strokes through three-dimensional cinematography. Three expert racquetball players and three expert squash players were involved in the data gathering process. The horizontal, vertical and lateral displacement of racket and trunk segment, intersegmental angular velocity of the wrist, elbow and shoulder joints, and the linear velocity of the racket were descriptively analyzed, and the followings were concluded. The racket of the squash backhand stroke showed an 'U' shaped movement where the racket moved rapidly downward and moved forward to make an impact and followed through to a front-top finish, while the racket of racquetball backhand stroke showed an 'O' shaped movement where the racket showed circular movement through the rear and bottom positions for the impact, and showed rotation through the lower-front and upper front to a upper-rear-ward finish during the follow-through. The peak velocity of racket was found before the impact point in the squash backhand stroke and at the impact point in the racquetball backhand stroke. For the final conclusion, for the squash backhand stoke, instructors might be better to make the racket move downward to make highest velocity before the impact and finished short follow-through, while for the racquetball backhand stroke, to make the racket move forward to make highest velocity at the impact and finished rather long follow-through.

This study was to analyze the Physical Activity Therapy Programs (PATPs) in U rban-rural region before and after COVID-19 in order to suggest a way of activating program. The subjects were the 43 PATPs performed in 4 Community Health Centers of Gimcheon, Jeongeup, and Pyeongtaek. The basic data was collected by official documents, expenditure budget, the homepage of the centers, national information disclosure portal, telephone interview, and e-mail with the person in charge of the programs. All the data were classified to the administrative districts, the health-related fitness variables, and the life cycles. The American College Sports Medicine Guidelines were used to evaluate the PATPs. As a results, the number of the PATPs was too small compared to the population of the regions. Also, the PATPs were not considered to the characteristics of participants such as Life-Cycle and regional facilities so on. The organization and management of the PATPs were principally deficient in improving health-related fitness variables. In 2020 as the period of COVID-19 pandemic, the number of programs and participants with face-to-face PATPs was significantlry decreased compared to 2019, while that was increased with non-face-to-face PATPs. In conclusion, PATPs should be increased and operated in accordance with scientific exercise prescription guidelines. Also, the programs should be considered with the proportion and characteristics of Life-Cycle population. Further, the various with non-face-to-face PATPs should be developed and screened with based on scientific data for post-corona virus pandemic. Further, non-face-to-face PATPs programs should include a kind of practical way to promote the individual physical activity.

Objective: The aim of this study was to investigate the effect of participation in contact sports on neurocognitive scores, dual-task walking velocity, and cognitive costs in retired athletes. Method: Forty-four retired athletes (mean age = 26.4±5.5 yrs) and thirty-eight controls (mean age = 26.1±4.9 yrs) participated in this study. Neurocognitive score was collected using computerized neurocognitive testing using RehaCom. Gait velocity was collected one single task, four dual-tasks, and two multi-tasks using Optogait. Mann-Whitney U test was performed to compared differences in cognitive scores among groups. A mixed-design two-way ANOVA and Bonferroni posthoc test were used to assess the effect of group and walking tasks for each condition. Results: The auditory divided attention of neurocognitive score of retired athletes was higher than the control group (p < 0.05). No statistical differences were observed in the other neurocognitive scores between groups. The changes in walking velocity and cognitive costs according to the dual-task walking tests differed between the two groups (p < 0.05). Conclusion: Although participation in contact sports did not affect the neurocognitive results of retired athletes, it could be confirmed that the reduction in walking velocity and an increase in cognitive costs during dual-task walking. Rather than observing only neurocognitive scores as a single evaluation item for cognitive evaluation of retired athletes in relation to daily life, the application of the dual-task gait test may provide useful information.

Objective: To compare head and hand movement patterns during squash forehand motions between experts and less-skilled squash players. Method: Four experts and four less-skilled squash players participated in this study. They performed squash forehand swings and a VICON motion analysis system was used to obtain displacement and velocity data of the head and right hand during the movement. Mann-Whitney U-tests were performed to compare head and hand range of motion and peak velocity, and cross-correlation was performed to analyze the head-hand coordination pattern between groups in three movement directions. Results: In terms of head and hand kinematic data, experts had greater head range of motion during down swings than less-skilled squash players. Experts seemed to reach peak hand velocity at impact by reaching peak head velocity followed by hand peak velocity within a given temporal sequence. In terms of head-hand coordination patterns, both groups revealed high positive correlations in the medial-lateral direction, indicating a dominant allocentric coordination pattern. However, experts had uncoupled coordination patterns in the vertical direction and less-skilled squash players had high positive correlations. These results indicate that the head-hand movement pattern likely an important factor squash forehand movement. Conclusion: Analysis of head and hand movement patterns could be a key variable in squash training to reach expert-level performance.
