Objectives: The purpose of this study was to determine whether the sacrooccipital category II blocking technique may improve abdominal muscle endurance and alleviate shoulder pain caused by pelvic tilting. Methods: A total of 50 subjects diagnosed with category II sacroiliac joint instability and lower back pain were randomly assigned to the control or treatment group. The sacrooccipital technique category II blocking procedure (2-min duration) was performed 3 times a week until the category II indicator of joint instability had subsided. The control subjects were subjected to a sham procedure of equal duration and frequency. We assessed abdominal muscle endurance using the partial curl-up test and shoulder pain using a visual analogue scale, before and immediately after the intervention and 2 weeks after the intervention. Results: On two-way analysis of variance with repeated measures on time factor, significant treatment and interaction effects on muscle endurance were found. A significant interaction effect, but not treatment effect, was found for shoulder pain. Post hoc test showed that the shoulder pain was reduced immediately after intervention (treated group) and 2weeks (control and treated group) after the intervention as compared to before the intervention. Conclusions: This study suggests that sacrooccipital category II blocking can be used to alleviate shoulder pain caused by pelvic instability. The mechanisms behind the long-term benefits may include an increase in abdominal muscle endurance.

The purpose of this study is to provide basic materials for amateur golf players or golf maniacs to learn desirable iron swing motions. This study compared and analyzed the swing motions of iron clubs(3, 6, 9) by using 3-D in three elite golf players. 1. There was no a great difference in the total of swing time by club and the time by phase was nearly similar. 2. There was no a difference in the change in a head location at address and impact by club. 3. The angle change in a right knee joint was similar by club except the difference according to the length of the club. 4. There was a subtle difference in hip rotation angle by club. 5. In each club, the same rotation angle of shoulder joint at address and impact motions contributed to accurate swing, and the maintenance of more than $90^{\circ}$ of shoulder rotation angle in top swing increased swing rotation. 6. Although subtle, the forward angle of upper body was increased with a shorter club. $30-36^{\circ}$ of forward angle of upper body was maintained at address, top swing, and impact motions.

PURPOSE: This study was to determine the effect of the plane of movement (sagittal plane vs. scapular plane) and shoulder flexion angle ($90^{\circ}$ vs. $130^{circ}$) during scapular protraction exercises in healthy subjects by investigating the elecromyographic (EMG) activities of the serratus anterior (SA), upper trapezius (UT), and pectoralis major (PM). METHODS: Twenty-one healthy subjects participated in this study. Subjects performed maximal scapular protraction at the $90^{\circ}$ or $130^{\circ}$ shoulder flexion angles in the sagittal or scapular planes. Surface EMG was recorded from the SA and UT, and PM muscles. Dependent variables were examined by 2 (plane) ${\times}$ 2 (angle) repeated measures of analysis of variance (ANOVA). RESULTS: Significantly increased EMG activities in the SA and UT were found during scapular protraction exercise at the $130^{\circ}$ shoulder flexion angle in the sagittal and scapular plane. Also, EMG activity of the PM significantly decreased at the $130^{\circ}$ shoulder flexion angle in the sagittal plane and the $90^{\circ}$ and $130^{\circ}$ shoulder flexion in the scapular plane. CONCLUSION: we recommend scapular protraction exercise at the $90^{\circ}$ shoulder flexion in the sagittal plane to selectively strengthen the SA muscle with limitation of upper trapezius activity and at the $130^{\circ}$ shoulder flexion in the scapular plane to selectively strengthen the SA muscle with limitation of pectoralis major activity.

In this study, a 3D simulation program was used to produce a bodice prototype of a middle-aged male in their 40s and 50s and then analyze the appearance evaluation and airgap, sectional view, color distribution through virtual wearing to compare and analyze the differences between patterns. Through this, it was intended to provide basic data necessary for pattern development to companies that manufacture and produce clothing for middle-aged men. As a result of analyzing, J pattern was analyzed as the most suitable body shape pattern for middle-aged men. E pattern was too tight and L pattern and N pattern had too much spaces. However, J patternt was analyzed that correction was necessary in setting center back and center front length. The aging phenomenon in which the back is slightly bent forward and shoulders are also inclined is expected to appear, so it is necessary to adjust the front-to-back length, shoulder angle, and shoulder length. It is considered that after developing the research pattern by modifying J pattern, it is necessary to develop a body shape prototype for middle-aged men through actual clothing experiments on middle-aged men.

The purpose of this study is to investigate the types and effects of rehabilitation by systematically examining the rehabilitation research for improving the shoulder ROM in breast cancer resection patients. For a systematic review, a total of 8 studies were finally selected through three databases including RISS. As a result of this study, the level of qualitative was 4 studies(50.0%) in level III, and the rehabilitation period varied from 4 weeks to 12 weeks. As for the type of rehabilitation, 3 studies(37.5%) were occupational therapy and physical therapy. The ROM of the shoulder joint was 7 studies(87.5%) of flexion, extension, and external rotation. A goniometer was used in 8 studies(100.0%) to evaluate the ROM of the joint as a measuring tool. This study is expected to provide basic data in the field of convergence when developing and applying interventional protocols for patients with limited ROM due to breast cancer resection.

사람의 몸 동작을 인식해야하는 여러 응용분야에서의 필요성이 대두되면서 이 분야로의 연구가 활발해지고 있다. 이 논문은 사람의 비언어적 행동을 자동적으로 분석할 수 있는 인식기 개발에 관한 것으로 실세계 3 차원 좌표값을 입력으로 하는 사람 몸 동작 패턴 분류기의 구현방법을 소개한 것이다. 하나의 사람 몸 동작은 각 몸 구성 성분(손, 아래팔, 위팔, 어깨, 머리, 몸통 등)의 움직임을 조합해서 정의한 수가 있기 때문에 개별적인 각 몸 구성성분의 움직임을 인식하여 조합해서 임의의 동작을 판별하려는 방법을 적용한다. 사람 몸 동작 패턴 분류기는 측정된 실세계 3 차원 좌표 자료를 양자화한 후 xy, zy 평면에 투영한 값을 자자 구한다. 이 결과를 각각 8 방향 체인 코드로 바꾸고 2 단계 체인 코드 평활화 사업을 하여, 4 방향 코드 체적화 및 대표 코드로의 압축단계를 거친다. 이로서 생성된 프리미티브 패턴나열들을 동작 클래스별로 분류하여 프리미티브 패턴나열의 확장으로 각각의 식별기를 구축하여 각 몸 구성 성분별 동작들을 분류한다. 일련의 실험이 행해져 그 타당성을 확인하였으며, 차후에 이 분류기는 비언어적 행동 분석을 위한 사람 몸 동작 인식기의 전처리 단계로 사용되어진 것이다.

I. 목적 : arm-up holder는 흉부 및 복부 질환 치료의 환자고정에 유용하게 사용하고 있으나 손잡이 부분과 어깨가 닿는 부분까지 거리 때문에 동일한 자세를 유지하는데 불편함이 있다. 특히 긴장을 많이 하거나 기력이 없는 환자는 방사선 치료 시 자세의 불안정으로 인하여 치료의 정확성이 떨어질 수 있다. 이에 본원에서는 현재 사용하고 있는 arm-up holder에 팔의 지지를 위한 보조기구를 제작하여 유용성을 평가하였다. II. 대상 및 방법 : 기존의 arm-up holder에 어깨받침대를 부착하여 개선된 arm-up holder를 제작하였다. 실험을 위하여 기존의 arm-up holder를 사용하는 환자그룹과 개선된 arm-up holder를 사용하는 그룹으로 구분하여 자세 변화를 평가하였다. 두 그룹의 환자를 대상으로 모의 치료를 실시한 후 치료실에서 L-gram 을 2회 씩 촬영하여 치료하고자 하는 portal film과 isocenter의 변화를 측정했다. 각 그룹 당 10명씩의 환자를 선정하여 반복 조사하였다. III. 결과 : 개선된 arm-up holder를 사용한 그룹의 isocenter 의 변화는 최대 2mm, 최소 0.5mm 평균 1.2mm 이다. 기존의 arm-up folder를 사용한 그룹과 비교하여 평균변화는 약 2배로 나라났고, 최대 변화는 2.5배의 오차범위가 측정되었다. IV. 결론 : 현재 사용하고 있는 arm-up holder는 흉부 및 복부의 사방향 방사선 치료 시 팔에 의한 방사선 감약을 예방할 수 있는 유용한 고정용구이다. 하지만 팔을 올리고 있는 자세는 환자에게 불편함을 야기 시키며 이로 인한 치료의 정확성을 감소시킬 수 있다. 따라서, 기존의 arm-up holder에 보조기구를 제작하여 사용함으로써 환자의 불편함을 개선하고, set-up 의 안정성과 재현성을 향상시킬 수 있었다.

Purpose: The purpose of this study was to determine the muscle activity ratio according to the shoulder abduction angle by identifying the mean muscle activities and calculating the muscle ratios for use in developing strengthening methods. Methods: The participants were healthy adults in their 20s (n=19). The activity of the deltoid middle, upper trapezius, middle trapezius, and lower trapezius muscles was measured by 8-channel surface electromyography. Muscle activity was measured during 4 conditions of angle of shoulder abduction: $30^{\circ}$, $60^{\circ}$, $90^{\circ}$, and $120^{\circ}$. The data used in the analysis were the root mean square and % total muscle activity values. Results: The root mean square values for the deltoid middle, upper trapezius, middle trapezius, and lower trapezius muscles showed significant differences. No significant differences were detected in the % total muscle activity of the deltoid middle, upper trapezius, middle trapezius, or lower trapezius muscles. Conclusion: Future studies aimed at developing selective shoulder abductor muscle strengthening methods are likely to provide more effective results by using muscle activity ratios.
