  • The aim of this study was to provide the 2 and 3 dimensional statistics requisite in the sizing system and design of gloves. The 64 2-dimensional static measurements were selected to provide information about hands. Participants in the study were 824 adults, aged between 18 and 64. To summarize the information from the measurement values, a Factor Analysis and a Cluster Analysis among multivariate analyses were performed. 3-D scanner was used for visual results of hand shape of each cluster. The results were as follows. Twenty-two items were used for the factor and cluster analysis in order to classify the adult hand shape. The variable quantities that are explained by a total of 3 factors amounted to under 79.37% of the variable quantities. The definition results of the factors related to the hands are as follows: Factor 1 is the horizontal dimension, the thickness of hand factor; Factor 2 is the height of the crotch; and Factor 3 is the vertical dimension of the hand. The adults' group hand was divided into 2 clusters according to a cluster analysis using factor scores. The characteristics according to hand type were as follows: Cluster 1 referred to high horizontal dimensions and thickness, rather small vertical dimensions and crotch height; and Cluster 2 represented the rather smaller horizontal dimensions and thickness but longer hand length than Type 1. To provide specific shape data of each cluster, 3-D scanner measurement was performed. 3-dimensional data base was developed for each cluster type and visual information was provided.

  • Background: This study aimed to determine the impact of complex decongestive therapy applications on upper extremity function in breast cancer patients who developed adhesive capsulitis after lymphedema. Methods: Thirty patients who developed adhesive capsulitis due to lymphedema were divided into two groups as study (n = 15) and control (n = 15) groups. Both groups received 20 minutes of exercise five days a week for three weeks using a Biodex isokinetic dynamometer, as well as a hot pack and TENS (Transcutaneous Electrical Nerve Stimulation) treatment to the shoulder joint. The study group received 45 minutes of intensive decongestive therapy along with the adhesive capsulitis treatment. The visual analogue scale was used to assess pain, circumference, and volumetric measurements were used to assess edema, and the Arm, Shoulder, and Hand Problems Questionnaire (DASH: Disabilities of the Arm, Shoulder, and Hand) was used to assess upper extremity functionality. The shoulder range of motion was evaluated. Results: Both groups had improvements in pain (P < 0.001), shoulder joint range of motion (P < 0.001), and upper extremity functionality (P < 0.001) after the treatment. There was a significant decrease in circumference and volumetric measurements in the study group (P < 0.001). However, no differences were seen in measurements in the control group. Conclusions: The results showed that complex decongestive therapy was beneficial in reducing lymphedema in breast cancer patients who acquired adhesive capsulitis due to lymphedema. Consequently, the authors believe that supplementing conventional physiotherapy with complex decongestive therapy will benefit patients.

  • The purpose of this study is to give the guideline to the pattern designing by supplying various images of the transformed shape of tailored collar with the location and angle of gorge line and laying measurement of the tailored collar while designing the tailored collar. The results of this study are as follows : Images of the sample at the case of 1cm of laying measurement looks 'urban', 'light', 'sharp', 'young', 'fashionable' and 'narrow' than that at the case of 7cm. When the laying measurement increases, the image of the sample looks more 'classical' and 'boorish'. The image of the sample 'light', 'sensuous' and 'young' at the case of sample of which laying measurements of the collar was 3cm. Second, at the case of sample whose laying measurements of the collar was 5cm, it was shown that the low location of gorge line made the image of the sample 'soft' and 'short'. On the other hand the image of the sample looked 'hard', 'keen' and 'long' by the high location of gorge line. Third, at the case of sample of which laying measurements of the collar was 7cm, low location of gorge line made the image of the sample look short. However, normal location of gorge line made the image of the sample looked 'fashionable'. The images of the samples of which laying measurements of the collar were 3cm, 5cm and 7cm, respectively, had changed with the angle of gorge line. First, the high angle of gorge line made the image of the sample 'rigid' and 'keen' at the case of sample of which laying measurements of the collar was 3cm. The high angle of gorge line made the image of the sample looked 'boorish' and 'singular'.

  • Objective: The purpose of this study was to investigate how light touch with a finger affects balance ability when a posture is maintained in the condition of visual information blockage and to provide a fundamental material for developing balance ability in the process of rehabilitation treatment. Design: Cross-sectional study. Methods: The study subjects were 17 healthy men and women in their twenties and thirties who were studying at S University in Seoul. The system was comprised of an equilateral triangular force platform. Subjects were asked to step on the foot position of the force platform (Good Balance, Finland) barefooted for 30 seconds, with eyes closed, hands hanging down loosely, and feet comfortably apart. It was connected to a laptop by using Bluetooth technology. An experiment was conducted in the following three circumstances: 1) no-touch trial, 2) light touch to the back (T7 area), and 3) light touch to the middle finger of the left hand. Each subject was given a 10-minute break between consecutive measurements. The experimental circumstances were performed randomly. Anteroposterior sway (APSV), mediolateral sway velocity (MLSV), and velocity moment (VM) were measured. Results: The APSVs (mm/s) were $9.32{\pm}3.37$ and $5.45{\pm}2.98$; the MLSVs (mm/s), $6.39{\pm}3.35$ and $3.31{\pm}2.48$; and VM ($mm^2/s$), $17.13{\pm}11.75$ and $6.76{\pm}8.31$ in the first and second experimental circumstances, respectively. APSV, MLSV, and VM values were significantly improved with the 1) no-touch trial and 2) light touch to the back trail conditions compared with the 3) light touch to the middle finger of the left hand condition (p<0.05). Conclusions: This study revealed that the balance ability for maintaining a body posture was influenced more by light touch to the back (T7) than by light touch with the sensitive fingertip and body sway diminished after visual information was blocked.

  • Purpose: This study compared the different sling and resistance exercises on pelvic rotation during active straight leg raises (ASLR) and on pain in patients with chronic low back pain (CLBP). Methods: Twenty subjects were divided randomly into a sling group (SG) and a resistance exercise group (REG). Internal oblique (IO), external oblique (EO), rectus abdominis (RA), and rectus femoris (RF) muscle activity; pelvic rotation angle during ASLR; and visual analogue scale, pressure pain threshold were measured. Sling and resistance exercises were then performed for 30 minutes and the measurements taken again. Results: Both groups showed significantly lower RF muscle activity and significantly higher EO and IO muscle activity (p<0.05). The RA muscle activity decreased significantly in the SG, but increased significantly in the REG (p<0.05). The pelvic rotation angle was significantly lower in the SG (p<0.05). The pain press threshold increased significantly in both groups (p<0.05). The visual analogue scale decreased significantly in the SG (p<0.05). Conclusion: Both exercises appear to be beneficial for modifying the muscle activity and pain control in the intervention of CLBP. On the other hand, the sling was more effective in increasing the pressure threshold than resistance exercise, and the pelvic rotation angle was reduced. Therefore, both exercises can help patients with CLBP change their muscle activity and control pain. CLBP patients should use a sling for short periods of time to learn to reduce the pain and control pelvic rotation.

  • 여러가지 약물에도 발작의 증세가 조절되지 않는 난치성 뇌전증 환자에서 다양한 치료법들을 시도해 볼 수 있다. 하지만 그 중 수술적인 방법이 필요한 환자에서는 수술 전 검사를 통해 발작부위의 절제부분을 결정한다. 정확한 병변의 측정과 안전한 수술을 위해 뇌 피질에 전극 삽입술을 시행한다. 피질에 삽입된 전극으로 단순히 뇌파만을 기록하는 것이 아니라 다양한 검사를 시도해 그 부위가 갖는 기능을 확인할 수 있고 그런 검사법 중 하나로 유발전위 검사법이 있다. 2015년 1월부터 2018년 12월까지 70명의 환자를 대상으로 측정된 파형의 경향이 의미하는 바를 분석하였다. 뇌 피질에 삽입된 전극에서 기록된 체성감각유발전위는 중심고랑의 주행경로를 찾아 일차운동영역 및 일차감각영역을 피해 수술 할 수 있다. 또한 청각유발전위와 시각유발전위를 이용해 청각피질과 시각피질에서 기능적 피질의 확인과 뇌파검사상 나타난 발작초점부위와의 관계를 비교해 절제부위를 결정하는데 도움을 주고 수술 후에 발생할 수 있는 기능적 장애를 최소화 할 수 있다.

  • 목적: 양안시차를 이용한 3D 입체영상 시청(관람) 시 성인과 아동의 동공간거리의 차이가 심도지각에 미치는 영향을 분석하였다. 방법: 성인의 동공간거리는 기준 동공간거리로 설정하고, 아동의 동공간거리는 초등학교 저학년을 대상으로 측정한 표본의 분석값으로 설정하였다. 이렇게 설정된 동공간거리 값에 따른 양안시차(binocular disparity)와 교차점의 위치(crossing location) 관계를 분석하였다. 결과: 설정된 동공간거리 값은 아동이 57.3 mm로 성인의 65 mm보다 작았다. 양안시차가 (+)방향으로 증가할 때 교차점의 위치는 스크린 뒤로 멀어지며 가파르게 증가한다. 또한 (-)방향으로 시차량이 증가할 때 교차점의 위치는 스크린 앞으로 멀어지며 완만하게 증가한다. 성인과 아동, 두 집단 간 교차점 위치의 차이(difference of crossing locations)는 양안시차가 (-)방향일 때 보다 (+)방향일 때 크게 나타난다. 즉 동일한 양안시차에 대하여 아동은 성인에 비해 근치감과 원치감이 더 크게 느껴질 것으로 예상할 수 있다. 결론: 동일한 양안시차 조건의 3D 입체영상을 시청(관람) 시 아동이 느끼는 입체감은 성인에 비해 깊이감이 더 크다. 그러므로 3D 입체영상 제작 시 아동의 동공간거리를 고려한 양안시차 설정이 필요하다.
