Power shoulder look is most noticeable trend in women's wear in the 09/10 season. Specially jackets with sharper angle and wider shoulder became the best item since then, and were chosen for must-have item by fashion directors. Jacket occupied 50% in power shoulder items. Its shoulder angle was from 0 to 30 degree but items with 15 degree stood out among them. There are three methods to make power shoulder look jackets; shoulder extension method with moving shoulder tip up and sleeve cap height, method of extension and cutting sleeve cap with shorten shoulder length, and method of extension and moving shoulder tip up in the sleeve with shoulder line like raglan sleeve. As a result, shoulder angle is higher, starting point of shoulder line is closer to side neck point and shoulder point is extender to outside for appearance and fit. In shoulder extension method, the arm hole line was drawn with care by matching joining shoulder seam and setting the sleeve into the arm hole. In sleeve cap transformation, it is desired that starting point shoulder angle is moved closely to side neck point. In case of the sleeve with shoulder line, it needs to consider enough ease of shoulder and upper arm. For making patterns of power shoulder look jacket, it need to consider arm hole line, shoulder length, shoulder point position, sleeve cap height and sleeve width with interpretation design facts. In this study, through the analysis clothing construction method of power shoulder jacket, it is of help to pattern making for various power shoulder design items.

The Purpose of this study is analysis characteristic of grasping power with each different shoulder horizontal angle. Twenty female university students with no shoulder dysfuction participated subject in three different positions of shoulder horizontal flexion with standing posture, shoulder 0° flexion, elbow 90° flexion, forearm 90° pronation, different positions is followed : shoulder 0° horizontal adduction shoulder 40° horizontal adduction, shoulder 40° horizontal abduction. The One-way repeated ANOVA test was used to determine the different in grip strength on three shoulder horizontal positions. On the average, in the hand grip strength, the horizontal neutral position is higher than horizontal adduction position with significant value. In particular, shoulder horizontal aduction was measured lowest grip strength between three positions.

본 논문에서는 어깨에서 팔의 돌림을 측정한다. 우선 안쪽 돌림과 가쪽 돌림에 대하여 각도를 측정하도록 한다. 측정에서 이상 유무와 관련된 증상을 파악한다. 그리고 이런 증상을 예방하는 방법까지 제시한다. 어깨에서 팔의 안쪽돌림과 가쪽 돌림의 돌림각은 70°~90°가 보통이다. 돌림각이 보통에 미달이거나 고통을 느끼면 어깨에 이상이 발생한 것이다.

Shoulder bone scan everyday life, sports activities at the side of the shoulder joint, or applying strong force in the lateral occurs. Mainly on upper arm abduction, temple, other rotational dislocation of the shoulder joint gahaejyeo as useful for observing the presence or absence of lesions is used. Shoulder PA oblique projection prevent distortion of the image due to the angle and the most useful diagnostic radiological investigate shooting angle. Shoulder blade body and the acromion and coracoid process Y-view is formed characters. $10^{\circ}$ angle between the shoulder blades and the acromion is the obstruction. $20^{\circ}{\sim}25^{\circ}$ to the Y-view of the humerus head looks superimposed, the position of the shoulder joint and seemed appropriate. $35^{\circ}$ of the humerus head superimposed on the Y-view, but above the humerus head and shoulder joints were distorted. When $45^{\circ}$ elevation observed on the side of the best has come Y-view also acromion and coracoid process is finished.

색상 기반 손 탐색 알고리즘은 색상과 움직임 정보만을 사용하기 때문에 근처에 다른 사람의 손이 오는 경우 이를 구분하지 못하는 단점을 가진다. 본 논문에서는 이를 극복하기 위해 어깨선 추출을 이용한 보다 정확한 손 위치 파악 알고리즘을 개발하였다. 어깨선 추출 알고리즘은 목 바로 아래 어깨 점을 시작으로 원형의 탐색 공간을 각 원형으로 돌아서면서 탐색을 하는 방법으로 어깨선을 추출한다. 이때 탐색 영역안의 각각의 각들은 임의의 영역을 가진다. 이 영역들에서 우리가 정의한 에너지 함수에 의해서 에너지 값을 계산하게 된다. 최종적으로 에너지 값이 가장 큰 각으로 어깨선을 추출해 나가는 방법을 취한다. 이러한 알고리즘을 이용하여 실제 동영상 내에서의 어깨선 추출을 실험하고 제안된 알고리즘의 우수성을 증명한다.

This study is intended to provide a basic clinical data useful for preventing shoulder injuries related to occupation and curing them, by measuring the shoulder muscle activity of normal adults in an arm posture type of a wide shoulder joint angle, according to several differences of hand grip force. In order to examine the shoulder muscle activity during hand grips at a variety of intensity, according to the arm posture type, MVCs of all subjects were measured, and %MVCs of anterior deltoid, supraspinatus, the upper trapezius and infraspinatus at 0 degree, 90 degrees and 160 degrees of shoulder angle were yielded according to the grip force in an arm posture type, changing the maximum grip force into 30%, 50% and 90%, randomly. When measuring the hand grip at 30%, 50% and 70% of the maximum grip force to compare %MVC of each group depending on the arm posture type, there were no significant differences of muscle activity at 0 degree of shoulder angle among anterior deltoid, supraspinatus, the upper trapezius and infraspinatus, but there were significant differences of it among them at 90 degrees and 160 degrees of should angle(p<.001). According to the results of post-hoc test, also, anterior deltoid had the highest muscle activity, whereas the upper trapezius had the lowest muscle activity.

The shoulder refers to the area connecting the human torso and arms, and plays a key role in moving both arms. In particular, it plays the most important role in sending both hands behind the head or away from our bodies. In this paper, we measure the angles of the medial and lateral rotations of the arm from the shoulder, identify the symptoms associated with abnormalities, and propose ways to prevent these symptoms. The angle of medial rotation and lateral rotation of the upper limb in the shoulder is generally 70° ~ 90°. If the angle falls below the reference value or feels pain, something is wrong with the shoulder. In addition, a total of 100 people (50 men and 50 women each) were tested to determine patients with abnormalities.

관찰적 작업자세 평가기법은 각 관절의 자세를 관찰 기록하여 자세 부하를 평가하는 실용적인 인간공학적 작업평가 기법이다. 본 연구에서는 각 관절의 불편도 지수와 전신의 자세 부하의 관계성을 모형화하고, 전신의 작업자세 부하를 평가하는 방법론을 제시하였다. 자동차 조립공정의 대표적인 작업자세들을 대상으로 하여 정적인 자세의 심물리학적 부하를 전신에 대하여 평가하였다 전신의 불편도는 비중립 자세를 취하고 있는 각 관절의 조합에 의해 영향을 받는다. 특히, 자동차 조립공정에서는 어깨 높이 이상의 작업을 대상으로 하는 경우에 어깨, 목, 허리, 손목 등에서 비중립 자세를 동시에 취하여 전신의 불편도가 큰 것으로 나타났다. 평가된 전신의 불편도와 각 자세의 관절별 불편도 지수의 관계를 다중선형회귀모형으로 모형화하는 것이 타당한 것으로 나타났다. 모형에서 전신 불편도에 가장 큰 영향을 미치는 관절은 어깨이며, 손목의 영향이 가장 적은 것으로 나타났다. 이 모형을 통해 작업자세 부하를 정량적으로 평가하는 것이 가능할 것으로 기대된다.

Firstly, medial rotation and lateral rotation is when moving a hand inward and outward, while raising a hand with the elbow parallelizing to body, while the shoulder aligning with the body. We would like to identify treatments when either medial rotation or lateral rotation causes pain, or when the rotation lacks of measurement angle, when measured.

The purpose of this study was to investigate the effect of scapular stabilization exercise and thoracic joint mobilization on scapular position, scapular motion and shoulder pain and disability index(SPADI) in adults with scapular dysfunction. A total 42 subjects were divided into a scapular stabilization exercise group(A, n=14), a thoracic joint mobilization group(B, n=14) and scapular stabilization exercise with thoracic joint mobilization group(C, n=14) and performed exercise and joint mobilization three times per week for four weeks, total 12 times. As for changes in scapular position among the groups, group C showed statistically significant increase(p<.05). In changes of scapular motion among the groups, group C showed statically significant improvement in shoulder abduction 45° and 90° both(p<.05), In changes of SPADI among the groups, group C were showed statistically significant improvement(p<.05). In conclusion, scapular stabilization exercise and thoracic joint mobilization were effective on improving scapular position, movement and SPADI score in adults with scapular dysfunction.
