The purpose of This study's aim is to examine the difference in the changes of body segment movement, variables for ball quality, and carry at golf driver swing according to the ball quality using comparative analysis. Regarding the impact variables according to the ball quality using the track man and carry, club speed was the fastest at draw shot, ball speed was the fastest at straight shot, and smash factor was the lowest at draw shot. About the vertical launch angle, the fade shot showed the highest launch angle while the max height of the ground and ball was the highest at fade shot. And carry was the longest at draw shot. For the flight time, it was the longest at draw shot. The landing angle was the largest at fade shot. About the club head position change and trajectory, at the overall event point, the fade shot drew a more outer trajectory at the point of the follow through(E6) than the straight or draw shot. Regarding the angular speed of shoulder rotation, at the overall event point, the fade shot showed the greatest angular speed change in the follow through(E6). Also, about the angular speed of pelvic rotation, at the overall event point, the draw shot showed the greatest angular speed change at the point of down swing(E4). Concerning the stance angle change, both straight and fade shots were open as the concept of open stance whereas the draw shot was close as that of close stance. Regarding the previous study, the most important factor of deciding Ball Quality is the club face angle's open and close state at Impact. In short, the Ball Quality and carry were decided by this factor.

Fat shot은 골프에서 공보다 뒤땅을 먼저 치게 되는 샷의 공식 용어이다. 본 연구에서는 fat shot과 정상적인 샷의 동작을 비교 분석하였다. K 대학교 교원 5명을 연구대상자로 선정하였으며, 개인별 fat shot이 최소 5개 체크될 때까지, 샷을 계속하게 하였다. AD, MBS, TBS, MDS, IMP, MF를 분석 시점으로 설정하였고, 구간 소요시간, 지면반력 패턴, 백스윙 크기, 팔꿈치 각도, 코킹 각도, 골반과 몸통의 회전, 골반 선속도 각속도 등을 분석하였다. 변인별 차이를 확인하기 위해 대응표본 검증을 실시하였다. Fat shot의 주요 원인으로 간주되는 다운스윙에서의 빠른 코킹 풀림, 다운스윙 초기의 오른 팔꿈치 신전, 뒷발에 체중을 실은 채로 하는 스윙 등의 형태는 나타나지 않았다. 백스윙 크기와 X-Factor 크기, 골반과 몸통의 회전각도, 골반의 회전각속도에서도 두 샷 간 차이가 나지 않았다. 그러나 정상적인 샷에 비해 Fat shot은 다운스윙 초반이 아닌, 후반부 임팩트 바로 직전의 다소 급격한 체중 이동 형태와 다운스윙 과정 중 골반의 타겟 방향으로의 급격한 가 감속, 그리고 골반의 수직 상방으로의 다소 작고 늦은 타이밍의 움직임 속도패턴을 나타내었다.

Objective: The purpose of this study was to investigate changes of abdominal muscles thickness according to the angle during the active straight leg raise (ASLR) in young healthy subjects. Design: Cross sectional study. Methods: Twenty-three healthy university students (13 men and 10 women) voluntary participated to the study in S University. The ASLR was performed with the subject lying supine with lower extremities straight on a standard plinth, hands resting on the chest, and elbows on the plinth. When one subject performed ASLR from each angles ($30^{\circ}$, $45^{\circ}$, $60^{\circ}$, $90^{\circ}$), compared changes in the thickness of rectus abdominis muscle. Changes in muscle thickness during ASLR test were assessed with ultrasonography. All subjects were to provide enough time of rest after performed ASLR. Rectus abdominis thickness were measured using rehabilitative ultrasound image. Results: Good quality rectus abdominal muscle activation data were recorded during ASLR. The length changes of linea alba showed significantly shorter in between $0^{\circ}$ and $30^{\circ}$ (p<0.05). The thickness of rectus abdominis muscle were significantly different between $0^{\circ}$ and $30^{\circ}$, $0^{\circ}$ and $45^{\circ}$, $0^{\circ}$ and $60^{\circ}$, $0^{\circ}$ and $90^{\circ}$. According to increase of pelvic angle, the thickness of rectus abdominis muscle were more thickening (p<0.05). Conclusions: This result is changes of abdominal muscles thickness according to the angle during the ASLR.

Objective: The purpose of this study was to analyze the differences in kinematic factors according to stretching treatment, myofascial release treatment, and static stretching treatment conditions during squat. Method: Twelve males with resistance training experience participated in this study. Participants performed squats without treatment (Pre-Test), and performed squats after treatment with the myofascial release technique (MRT) and static stretching (SS) on different days (post-test). Squat movements were captured using eight motion capture cameras (sampling rate: 250 Hz), and the peak joint angles of the ankle, knee, hip, and pelvis were calculated for each direction. One-way repeated ANOVA and Bonferroni post hoc analyses using SPSS 27 (IBM Corp. Armonk NY, USA) were used to compare the peak joint angle of the lower extremity joints and pelvis among the normal condition (squat without treatment), MRT condition (squat after MRT treatment) and SS condition (squat after static stretching). The statistical significance level was set at .05. Results: It was observed that the maximum ankle joint flexion angle during squats was statistically reduced under conditions of myofascial release and static stretching (p<.05), in comparison to the scenario where no stretching was performed. Furthermore, static stretching was found to enhance the maximum hip flexion angle during squat (p<.05), whereas the myofascial release stretching technique resulted in the minimal posterior pelvic tilt angle (p<.05). Conclusion: Employing myofascial release stretching as a preparatory exercise proved to be more efficacious in maintaining body stability throughout the execution of high-intensity squat movements by effectively managing the posterior tilt of the pelvis, as opposed to foregoing stretching or engaging in static stretching.

Purpose: This study was conducted in order to investigate the exercise limit that may occur depending on changes in postural alignment by examining the significance of postural alignment changes, foot pressure, and balance of patients with stroke. Methods: In this study, 50 patients diagnosed with a stroke were selected as subjects. Imbalance of postural alignment of the trunk, pelvic tilt of trunk rotation of the body, angle of kyphotic curving of the thoracic, and angle of lordotic curving of the lumbar vertebra were measured. Foot pressure was examined by measuring average pressure and weight bearing. Balance was examined by measuring the center of pressure and limit of stability. Results: The significance of postural alignment, foot pressure, and weight bearing of the non-paretic side was examined. In addition, the significance between postural alignment and balance was examined. Conclusion: It is thought that limits of foot pressure and balance in the standing position can be caused by postural alignment. Thus, both a therapeutic intervention program and postural alignment training should be provided together in order to improve the function of patients with stroke.

In this study, we would be developed the fuzzy controlled PGO that controlled the flexion and the extension of each PGO's hip joint using the bio-signal and FSR sensor. The PGO driving system is to couple the right and left sides of the orthosis by specially designed hip joints and pelvic section. This driving system consists of the orthosis, sensor, control system. An air supply system of muscle is composed of an air compressor, 2-way solenoid valve (MAC, USA), accumulator, pressure sensor. Role of this system provide air muscle with the compressed air at hip joint constantly. According to output signal of EMG sensor and foot sensor, air muscles and assists the flexion of hip joint during PGO gait. As a results, the maximum hip flexion angles of RGO's gait and PGO's gait were about $16^{\circ}\;and\;57^{\circ}$ respectively. The maximum angle of flexion/extention in hip joint of the patients during RGO's gait are smaller than normal gait, because of the step length of them shoes a little bit. But maximum angle of flexion/extention in hip joint of the patients during PGO's gait are larger than normal gait.
