The purpose of this study is to classify the types of men's shoulders through the criteria which represent the characteristic of men's shoulders. In addition, we introduce new bodice patterns depending on our classification. We have the fo11owing conclusions based on our sample size of 200 men's shoulders: 1. The result of factor analysis indicates that six factors are extracted and they consist of 62.3% of total variance. We then choose three factors as standard items for our classification of the shape of men's shoulders. 2. We divide the shape of shoulders into three categories: bent, slopeness, and thickness. Each category is divided into three subcategories. (a) Bent: If one's shoulders are bent forward or backward, then we call them front or back-bent type. Otherwise, they are called standard-bent type. (b) Slopeness: If one's shoulders have an easy or steep slope, then we call them easy or steep slope type. Or else, they are called standard slope type. (c) Thickness: If one's shoulders are thick or thin, then we call them thick or thin type. Otherwise, we call them standard thick type. 3. According to the frequency based on our data entries of 200 men's shoulders, we introduce five new types of men's shoulders. 76.5% of examined men's shoulders belong to one of these five types: (a) 8.0% of standard slope and back-bent type: (b) 9.5% of easy slope and standard-bent type; (c) 45.5% of standard slope and standard-bent type; (d) 5.5% of steep slope and standard-bent type; (e) 8.0% of standard slope and back-bent type. 4. The suitability of new basic bodice patterns based on the types of men's shoulders are demonstrated by the high approval rate of the subjects who participate in testing.

The purpose of this study is to use standard and downward slope of the keyboards with taping to influence electromyography of upper trapezius. The effect of taping raise a medical criticism, but we do an experiment on two kind of keyboards with taping in order to decrease stress of shoulder. Subjects are in Seonam university whose are twelve healthy adults in their twenties. This experiment used two kind of keyboards. Standard keyboard's degree is $0^{\circ}$ and another keyboard's degree is $-7.5^{\circ}$. Application of Kinesio taping attached belly of upper trapezius tightly. Measurement of electromyography attached posterior of acromion process go by spinous process of 7th cervical vertebra and upper trapezius. Method of analysis used Repeated measure two-way ANOVA. Result of this experiment, both shoulder's muscle activity increased(p<.05) when used standard keyboard and downward keyboard with taping used. We compared muscle activity that used downward keyboard than standard keyboard. Statistically, it dosen't increase in neck and shoulder(p>.05). Therefore, using a keyboard with upper trapezius's taping in order to decrease muscle activity isn't influenced.

Background: Prolonged neck flexion during smartphone use is known as a factor of neck pain and alteration of neck muscle activity. Studies on the effects of shoulder taping on neck discomfort and neck muscle responses while texting on a smartphone are still lacking. The aim of this study was to examine the effects of shoulder taping on neck discomfort using a numerical rating scale, and neck muscle activity and fatigue using a surface electromyography during a texting task on a touchscreen smartphone. Methods: Twenty-five healthy adolescents used the dominant hand to perform a 30-minute texting task using a touchscreen smartphone at two separate times under one of the following two conditions: taping across the upper trapezius muscle and no taping. Neck discomfort, normalized root mean square, and normalized median frequency slopes for upper trapezius, cervical erector spinae, and sternocleidomastoid muscles were recorded. Results: The results revealed that shoulder taping provided significantly lower neck discomfort than no taping (p < 0.001). However, shoulder taping did not significantly alter normalized root mean square and normalized median frequency slope values of all muscles when compared with no taping controls. Conclusion: Shoulder taping reduces neck discomfort but does not affect neck muscle activity and fatigue while texting on a touchscreen smartphone.

Background: To report the radiological and clinical outcomes of internal fixation using distal clavicle hook plates for distal clavicle fractures. Methods: From April 2008 to December 2012, 32 patients with distal clavicle fractures underwent surgery using an AO hook plate. The reduction was qualified and evaluated according to the radiological findings. The evaluation of the clinical outcomes was performed with the University of California at Los Angeles (UCLA) score, the Korean Shoulder score, and the visual analogue scale (VAS) pain score. Results: By radiological evaluation, we found that 31 of 32 patients showed anatomical reduction and solid bone union. Although we obtained satisfactory UCLA scores, Korean Shoulder Scale scores, and VAS pain scores, 12 cases of complications were present. We found 4 cases of osteolysis of the acromion, 1 case of nonunion, 3 cases of periprosthetic fractures, 3 cases of subacromial pain, and 1 case of skin irritation. We performed re-operations in 2 patients. Conclusions: To avoid complications associated with clavicle hook plates, choosing the appropriate hook size and bending of the hook according to the slope of the acromion undersurface is critical. Also, we believe that early removal of clavicle plates may help reduce complications.

최근 산업의 발달로 증가하는 도로와 이를 이용하는 차량의 증가로 인한 교통사고가 지속적으로 증가하고 있다. 교통사고는 운전자과실, 차량결함, 주행도로상태, 자연환경 등의 다양한 불안정 인자들로 인하여 발생한다. 방호울타리의 한 종류인 가드레일은 교통사고 및 이탈을 방지하여 탑승자의 상해와 차량의 파손을 최소로 줄여 차량을 정상주행 시키는 것을 목적으로 한다. 가드레일은 8 tonf 차량이 $15^{\circ}$로 80 km/h의 속도로 가드레일에 충돌하는 시험으로 가드레일의 안정성을 평가하며, 지반은 상대적으로 지지력이 큰 무한평지에서 평가된다. 하지만 국내의 경우 성토사면에 설치된 가드레일은 보호길어깨에 설치되며, 이로 인해 가드레일의 지지력 저하 및 성능저하로 가드레일의 안정성에 문제가 발생할 가능성이 있다. 이러한 가드레일에 대한 기존 연구는 무한평지에 설치된 가드레일 및 차량의 안정성에 대한 연구가 수행되었다. 하지만 차량 충돌 시 가드레일이 설치된 성토사면의 거동에 대한 연구는 미비한 실정이다. 이에 본 연구에서는 차량 충돌 시 성토사면의 거동을 확인하기 위해 유한요소프로그램인 LS-DYNA를 이용하여 성토사면에 설치된 가드레일의 지주 매입깊이를 변화시켜 수치해석을 수행하였다. 그리고 수치해석은 NCAN(National Crash Analysis Center)에서 제공하는 8 tonf 트럭을 이용하여 성토사면에서 가드레일 지주의 매입깊이를 변화시키면서 충돌 해석을 수행하였다. 그 결과, 가드레일 지주의 매입깊이가 증가함에 따라 성토사면의 변위와 응력이 증가하는 것으로 나타났으며, 450 mm 깊이에서 지반지지력이 저하되는 것으로 나타났다.

The purpose of this study was to investigate the effect of cross arms and palms facing forward on spinopelvic parameters during the whole spine lateral radiography. In addition, we would like to present the usefulness of a posture with the palm facing forward during whole spine lateral radiography of the spine using EOS. The subjects of this study were images of a total of 50 patients (18 males, 32 females) who whole spine lateral radiography using the conventional method and the EOS method from October 2020 to March 2021. The posture used in this study was set as 'CAP' for cross arms and 'PUSH' for posture with palms facing forward. In this study, among the spinal stability factors, thoracic kyphosis (thoracic vertebrae 4 to 12), lumbar lordosis (lumbar vertebrae 1 to sacrum 1), sagittal vertical axis, sacral slope, and shoulder flexion angle were compared on average. The mean thoracic kyphosis was 34.52±12.46° for CAP and 28.46±10.81° for PUSH (p<0.01). The lumbar lordosis of CAP was 42.45±17.45°and that of PUSH was 40.56±16.14°(p>0.57). The sagittal vertical axis was 26.59±34.34 mm in CAP and 21.21±35.41 mm in PUSH (p>0.44). In CAP, the sacral slope was 30.96±10.29°, and in PUSH, it was 31.01±10.19° (p>0.98). shoulder flexion angle was 38.31±8.24° for CAP and 26,08±6.71° for PUSH(p<0.01). As a result of this study, the PUSH posture is considered to be a posture that can minimize the shoulder flexion angle and can perform a stable examination while minimizing changes in spino-pelvic parameter.

The purpose of this study is grasp the problem of the gymnast, Kim, Dong-Hwa's Kip to Swallow Motion in Rings, and make up for the weak points to help him to perform a better performance. Therefore, two tryouts for $28^{th}$ Athens Olympic Games were filmed using video camera then finalized with Kinematical Analysis using 3D motion analysis program followings are the form of conclusions. 1. In the very first tryout, when he was doing a Swallow Support Scale, his CM position was high and arm slope was deduction because when he was doing Kip, the ascent velocity was low and he tried excessively to pull him on rings due to relying upon angular movement of shoulder joint. 2. When he was doing drop, he let his hip angle bend only little bit and let fall so making shoulder angle wider and maintain the level horizontally occurs strong drop motion when vertical descent is happening. 3. As a result, lowering the direction of a kick makes CM's movement path lower, increase vertical ascent velocity, and it helps to do the Swallow Support motion in short period of time. 4. After a strong drop motion, which is deep and fast, would make rope of ring shake so there is a defect that the body moves to forward area. However, it does not effect in Swallow Support Scale motion. 5. In the second tryout, trunk rotation angle and arm slope was fixed decrease while doing rotary motion. When rotary motion was happening, before the body was going under the rings, maintained his arm slope horizontally so his Swallow Support Scale motion was nearly perfect.
