Purpose : We aimed to evaluate the impact of a exercise with kinect-based mixed reality device (KMR) on physical function, upper extremity disability, fatigue, and quality of life in breast cancer survivors. We hypothesized that this exercise program would improve physical function, physical activity, fatigue, and quality of life. Methods : Thirty-nine breast cancer survivors were randomized to either the KMR exercise group (KE) or the home stretch group (HS). The KE participated in 8 weeks of exercise, exercising 3 times per week, while the HS performed 8 weeks of stretching exercises, also 3 times per week. Before and after the intervention period, participants underwent assessments of physical function, including body composition, chester step test (CST), and hand grip strength (HGS). Additionally, participants completed questionnaires including the international physical activity questionnaire (IPAQ), disabilities of the arm, shoulder and hand (DASH) questionnaire, and functional assessment of cancer therapy-breast (FACT-B) questionnaire to measure their physical activity levels, upper extremity disability, and quality of life, respectively. Results : Overall, significant improvements were observed in several shoulder movements, body weight, and physical activity, with no significant interaction effects between groups and time. Furthermore, there was a significant group by time interaction for body weight, left flexion, right flexion, right abduction, and left adduction, as well as for upper extremity disability (K-DASH) and quality of life (FACT-B). Conclusion : In conclusion, the KMR exercise program was found to be effective at improving physical function, upper extremity disability, quality of life, and overall well-being in breast cancer survivors. The significant improvements observed in multiple measures and the significant group by time interactions for various outcomes highlight the potential benefits of this KMR exercise program in promoting a better quality of life for breast cancer survivors.

데이터의 영구 보관과 자유로운 복제 및 유통이 가능한 현대 디지털 사회의 특징으로 인하여 인터넷은 모든 것을 기억하는 세상으로 발전했다. 때문에 영원히 잊히지 않는 데이터들로 인해 피해를 입는 사례가 증가하였고, 인간의 본성인 '망각'을 인터넷상에 적용시키자는 소위 '잊힐 권리'를 요구하는 움직임이 많아지고 있다. 그러나 인터넷 사용자들이 보장받길 원하는 다양한 측면에 있어서의 더욱 높은 수준의 잊힐 권리는 다른 기본권과의 충돌 등 여러 가지 문제들에 막혀 법리적인 접근만으로 더 이상의 의미 있는 진전을 이루기 힘든 상황에 처해져 있는 실정이다. 반면 잊힐 권리를 보장받기 원하는 개인들의 요구들은 휘발성 SNS, 디지털 에이징 시스템(Digital Aging System) 등의 디지털 소멸 기술의 발전을 촉구시켰다. 디지털 정보에 소멸 기한을 설정하여 망각의 개념을 도입한 디지털 소멸기술은 인터넷상의 잊힐 권리 보장 확대에 있어 새로운 해결 방향을 제시해줄 수 있을 것으로 생각된다. 본 연구에서는 다양한 영역의 잊힐 권리에 대해 세부 범위를 설정하고, 국내에서 잊힐 권리 어느 정도의 수준으로 보장되고 있는지 분석하며, 분석된 범위들에 대해 디지털 소멸 기술을 통한 잊힐 권리 보장 가능성을 제시한다.

Introduction: Surgical treatment of subclavian artery (SA) injury is challenging because approaching the lesion directly and clamping the proximal artery is difficult. This can be overcome by using an endovascular technique. Case 1: A 37-year-old male was drawn into the concrete mixer truck. He had a right SA injury with multiple traumatic injuries: an open fracture of the right leg with posterior tibial artery (PTA) injury, a right hemothorax, and fractures of the clavicle, scapula, ribs, cervical spine and nasal bone. The injury severity score (ISS) was 27. Computed tomography (CT) showed a 30-mm-length thrombotic occlusion in the right SA, which was 15 mm distal to the vertebral artery (VA). A self-expandable stent($8mm{\times}40mm$ in size) was deployed through the right femoral artery while preserving VA flow, and the radial pulse was palpable after deployment. Other operations were performed sequentially. He had a viable right arm during a 13-month follow-up period. Case 2: A 25-year-old male was admitted to our hospital due to a motorcycle accident. The ISS was 34 because of a hemothorax and open fractures of the mandible and the left hand. Intraoperative angiography was done through a right femoral artery puncture. Contrast extravasation of the SA was detected just outside the left rib cage. After balloon catheter had been inflated just proximal to the bleeding site, direct surgical exploration was performed through infraclavicular skin incision. The transected SA was identified, and an interposition graft was performed using a saphenous vein graft. Other operations were performed sequentially. He had a viable left arm during a 15-month follow-up period. Conclusion: The challenge of repairing an SA injury can be overcome by using an endovascular approach.

목 적 : 일상생활에서 하루 밤의 수면박탈은 흔히 있을 수 있다. 저자들은 전산화 신경인지검사를 통하여 38시간의 수면 박탈이 상지의 미세 운동수행능력에 어떠한 변화를 주는지를 연구하고자 하였다. 방 법 : 고려대학교 의과대학에 재학중인 학생중 정신적, 신체적으로 건강한 지원자 24명(M:F=21:3, mean age : $24.67{\pm}1.37$)을 대상으로 하였으며 모두 오른 손잡이었다. 또한 수면일지를 작성하게 하여 평소에 수면부족을 보이는 군은 배제하였다. Vienna Test System에서 나타날 수 있는 학습효과를 최소화하기 위하여 검사 하루 전에 미리 같은 검사를 시행하였다. 검사 전날 밤에 피험자들은 충분한 수면을 취하였으며, 검사 당일 오전 6시경에 기상하였다. 실험 첫날 오전 6시부터 다음날 오후 8시까지 38시간동안 수면을 박탈하였으며, 검사 첫날과 둘째 날의 오전 7시와 오후 7시, 총 4차례 Vienna Test System중 Motor Performance Series를 시행하였다. 실험기간 중에 모든 피험자에게 수면에 영향을 줄 수 있는 약물의 복용은 금지되었으며, 과도한 운동도 금지되었다. 자료는 SPSS를 이용하여 피험자당 4회 시행한 검사 결과를 Repeated ANOVA를 시행하였으며, 일중리듬을 고려하여 각 아침, 저녁 session끼리의 검사 결과를 paired t-test를 시행하여서 비교하였다. 결 과 : Motor Performance Series에서 수면박탈에 따라서 상지의 오른손의 운동 기능에 있어 수행능력의 저하가 나타났다. 각 소검사를 보면 tapping의 total number(p<.005), line tracking의 number of misses(p<.05), length of misses (p<.05), inserting short pin의 total length(p<.01), inserting long pin의 total length(p<.05), aiming의 number of misses (p<.05)에서 통계적으로 유의미한 기능의 저하가 나타났다. 결 론 : 이상의 결과는 38시간의 수면박탈만으로도 유의미한 운동기능의 저하가 나타난다는 것을 보여준 것이며, 특히 가장 예민하게 미세 운동기능을 발휘할 수 있는 우세한 오른손에서 기능저하가 나타났다. Inserting long pin보다는 inserting short pin 검사에서 기능이 저하되었고, line tracking, aiming에서 검사 결과의 수행 저하가 두드러진 것으로 보아서, 미세한 운동기능일수록 영향을 많이 받는다고 할 수 있겠으며, line tracking에서 전체 검사 시간은 감소되며, 수행에서 실수가 늘어난 것으로 보아, 수면박탈에 따라서 조급한 수행이 이루어진다고 보여진다. 또한 주어진 32초간의 시간 안에 최대한의 속도로 펜을 두드리는 tapping 검사에서 두드러진 저하를 보인 점에서, 수면박탈에 의하여 근육의 피로가 쉽게 나타난다고 생각 할 수 있겠다.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelves meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in twenty healthy volunteers when they were sleeping or waking respectively, to do significance test for electric potential of meridian system between hand and foot meridian, yin and yang meridian, exterior and interior of the body, and among the five elements. Methods : When twenty healthy volunteers were sleeping, their electric potentials of well and sea points in branches of the twelve meridians were simultaneously measured by physiograph. After a minute we measured them again, totally 5 times. And then when they were waking, their electric potentials were measured 5 times by the above method. Results : Measurements were analyzed by statistical t-test, we obtained that the left side electric potential of hand or yin meridian was significantly different from that of foot or yang meridian both sleeping and waking. The right side of electric potential was the same result as the left side's. Most of the t-test was significant between exterior and interior of the body, and among the five elements. That meaned that it was partly possible to apply the ancient theory of meridians to the study of electric potential at well and sea points in branches of the twelves meridians.

Distal limb deformities are congenital malformations with phenotypic variability and high genetic heterogeneity. Split hand/foot malformation, also known as ectrodactyly, is a congenital limb malformation characterized by a defect of the central rays of the hands and/or feet. Split hand/foot malformation with long-bone deficiency (SHFLD) is a rare condition related to a 17p13.3 duplication. Recently, genomic duplications encompassing BHLHA9 have been associated with SHFLD. We report a case of SHFLD presenting with campomelia of the right femur, bilateral agenesis of fibulae, bilateral club feet, and oligosyndactyly of the hands and feet, that was associated with a 17p13.3 duplication, as determined prenatally using array comparative genomic hybridization.

The purpose of this pilot study was to identify the effects of hand moxibustion therapy to decrease pain and relieve coldness of the body in women who had a hysterectomy. The conceptual framework of this study was derived from Ying-Yang, Khi and other corresponding theories. The data were collected from February to May 1997. A Graphic Rating scale was used to measure the degree of pain and Digital Infrared Thermographic Imaging(D.I.T.I) was used to examine the degree of coldness. The subjects were women who resided in Seoul and had a hysterectomy within five years. An experimental group was composed of five women who received moxibustion and a control group was composed of five who did not. The research procedure began with having both the experimental group and control group describe their general characteristics and the degree of pain they perceived. Then, Digital Infrared Thermographic Imaging(D.I.T.I) was conducted. Moxibustion was only given to the experimental group on both hands twice every day for a total of five weeks. Their perception of pain and D.I.T.I were examined weekly. The control group received no therapy. After finishing therapy, the perception of pain and D.I.T.I for both groups were also measured. According to this study, moxibustion therapy resulted in a change of body temperature on the right shoulder joint(p=0.00074), abdomen(p= 0.0047), waist(p=0.0068) and hands(p=0.0317) respectively. Also, the study results showed significant decrease (p=0.0001) in pain over time and significant improvement over body coldness.

Purpose: Finger injury by green onion cutting machine is one of the common hand injuries in the kitchen. It has a unique feature: there are multiple parellel laceration 3 - 5 mm wide. There are two directions of injuries(vertical, oblique). It may involve bone, tendon, nerve, and vessel injuries. We discuss its management and the long - term progress. Methods: We have treated six patients from 2003 to 2007. We carried out low tension approximation with thin suture materials to avoid ischemia and performed the additional operation as nail bed repair, tenorrhaphy, open reduction, vessel anastomosis, and composite graft. We reviewed the record of initial injury and collected the follow - up record. Results: They were all middle aged - women who had worked in the kitchen. Right hand was dominent over left hand. The ratio of the directions was 3 : 3 (vertical : oblique). They were all competely healed although there were three atrophy, four hyperesthesia, and one nail deformity. Conclusion: Finger injury by green onion cutting machine is a unique pattern of laceration with various accompanied injuries. It may look like a severe form of injury, but in most cases have relatively favorable progress. We have to perform careful examination of accompanied injuries and carry out the proper management. First and foremost, the user especially in the middle aged women should be warned to be careful in handling this risky machine.

Objective : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in twenty aged and fifty aged healthy volunteers groups at sleeping(SG) and awakening(AG), and then to find out the characteristic of meridian system among 2 groups. Methods : We selected who thirty healthy volunteers were diagnosed by a blood test, urine examination and differentiation of syndromes by five viscera(五臟辨證) among volunteers. Their electric potential of well and sea points in the meridians were simultaneously measured by physiograph. Results : Measurements were analyzed by statistical factor analysis, we obtained that the both left and right side electric potential of well and sea points in branches of the twelves meridians were unclearly divided into four factors according to age and whether sleeping or not, which were the three Yin meridians of the hand, the three Yang channels of the hand, the three Yin meridians of the foot, and the three Yin meridians of the foot. Conclusion : In conclusion, using the sequently measuring method, we obtained that electrical potentials of well and sea points in branches of the twelves meridians were divided into two factors, but the simultaneously measuring method, those were divided into four factors. The latter result means that the electrical potentials of twelve meridians were reflected by the function of the viscera and bowels.
