Costume elements are closely related with human living environment and also play an important role in the costume patterns. The East and the West have influenced and adopted each other's culture through mutual trade, which are well reflected in costume patterns and textile patterns. These days world wide fashion shows the designs applying costume details of the East and the West, which is much affected by the orientalism. The purpose of this study is to compare the sleeve patterns which take an important part in women's costume design of the Joseon Dynasty and the European Monarchy in the 16th century. Korean women's costume showed sleeves in rectangular shape with same width and long length, together with cuffs. Later they changed to diagonal shape of getting narrower toward the wrist. Western women's costume showed sleeves with puff and slash patterns. Then they were classified into French, British and Spanish styles which were getting narrower toward the wrist. Later they adopted the shape of leg of mutton which was puffed in middle and narrower toward the wrist. I n Korea and Europe, they showed respective changes in sleeve patterns, but also similarity of getting narrower toward the wrist. The East and the West are now exchanging their culture in every aspect such as politics, economics and social matters. Costume fashion is not an exception. The characteristic designs of traditional costumes are shown on global fashion, which is influenced by the orientalism.

The rehabilitation training robots for treating the upper limbs of stroke patients were mainly focused on the upper proximal treatment of it, but recently studies of the distal parts of the upper limbs for rehabilitation of the hand is making some progress even though it is still a small number so far. In this paper, we present the hand robot for the rehabilitation training of stroke patients that is the fingertip contact-typed mechanism, and it has also equipped with the wrist rehabilitation unit to be worked like human hand that enables any movements through mutual cooperation by fingers while picking up or grasping objects. The robot that is presented for this purpose supports the movement of fingers with 5-DoF and the wrist with 3-DoF that moves independently, and operates with a structure that allows the joints of the wrist and fingers to be collaborated organically together to each other. Also, hereby the simulation and evaluation test on its robot mechanism are performed to ensure that fingers with 5-DoF and the wrist with 3-DoF of the serial kinematical mechanism are designed to comply with or exceed ROM for ADL.

This study reports an optimization of a 3D printed wrist brace (WB) for various tilting angles (0°, 45°, 90°) of the re-entrant (RE) pattern and thickness (2 mm, 4 mm) using thermoplastic polyurethane (TPU) filaments and thermoplastic elastomer (TPE) filaments. The actual printing time, weight, Poisson's ratio, and tensile property of the manufactured samples were analyzed. The results confirmed that the actual printing time and weight increased with increasing thickness, regardless of the filament type. All tilting angles of the WB showed a negative Poisson's ratio (NPR), the largest of which appeared at 90°. The results of the tensile property analysis showed that a 90° tilting angle also had the largest value of elongation and stress. From these results, we conclude that the most suitable wrist brace is one in which the actual printing time is low, the weight is minimized to a thickness of 2 mm, and the tilting angle of the RE pattern is 90° for good shock absorption. The choice of filaments may be decided upon according to the user's preference, since the TPU is stiff and the TPE is elastic.

The triangular fibrocartilage complex (TFCC) is crucial for stabilizing the ulnar side of the wrist but can be partially torn due to degenerative changes, falling, or sudden injuries. However, only a few studies have focused on the use of Korean medicine treatments for TFCC-related wrist pain. This case report presents the successful outcomes of integrated Korean medicine treatment in a patient with a partial TFCC tear. The diagnosis was confirmed via magnetic resonance imaging, which revealed the tear. Subsequently, the patient received integrated Korean medicine treatments. The assessment of the pain scale scores revealed a significant reduction in wrist pain and an improvement in daily life activities. Based on the findings of this study, integrated Korean medicine treatments have been proven to be an effective treatment option for patients with a partial TFCC tear. However, further research is needed to determine the potential benefits and mechanisms of these treatments in managing TFCC-related wrist pain.

Objective: The purpose of this study was to investigate the effects of vibration resistance exercise (VRE) in patients with tennis elbow on strength, range of motion (ROM), function, pain and quality of life (QOL). Design: Randomized controlled trial. Methods: Twenty-seven participants were randomly assigned to either the VRE group (n=9), weight resistance exercise (WRE) group (n=9) or control group (n=9). Each group underwent hot compress for 15 minutes and electrotherapy for 15 minutes. The VRE group underwent exercises using a vibrating ball for 5 minutes. The WRE group underwent exercises using dumbbells for 5 minutes. All participants were evaluated on wrist extension strength using a hand-held dynamometer, grip strength level through an electric dynamometer, and ROM through a smartphone goniometer application before and after intervention. Patient-rated tennis elbow evaluation, Visual Analogue Scale and Short Form 8 were measured by questionnaires. Results: There were showed significant differences among the VRE, WRE and control group in wrist extensor muscle and hand grip strength, ROM, elbow function, pain and QOL after intervention (p<0.05). The VRE group showed a greater significant improvement in wrist extensor muscle strength and elbow function compared with the others (p<0.05). The VRE and the WRE groups had a more significant improvement in wrist extensor muscle and hand grip strength, ROM and pain compared with the control group (p<0.05). However, there were no significant differences in QOL among the three groups. Conclusions: Combining VRE with thermotherapy and electrotherapy appears to be more effective in improving wrist extension strength, ROM, elbow function, QOL in tennis elbow patients.

Although the genetic basis for bone mineral density (BMD) has been studied by many groups so far, genes responsible for this complex trait has not been completely revealed. In order to localize quantitative trait loci (QTLs) for BMD variation in Asian population, the study was designed using a group of Mongolian population, a genetically closed population with a homogeneous lifestyle. BMD was measured at the left and right wrists and ankles using DEXA in 1,082 participants from 142 families. Genotyping of 13 polymorphic microsatellite markers on chromosome 13 (average spacing 8-9 cM) and two-point and multipoint linkage analysis were performed. In two-point linkage analysis, we identified two markers, D13S175 (6.03 cM) and D13S265 (68.73 cM) that had LOD scores greater than 1 for left ankle (LOD=2.09, LOD=1.49, respectively). We also found a marker D13S175 (6.03 cM) with a high LOD for left wrist (LOD=1.49) and the markers D13S265 (68.73 cM) and D13S217 (17.21 cM) for the right wrist (LOD= 1.82, LOD= 1.62, respectively). Among these significant marker regions, only two regions at 17 cM (13p11) and 65 cM (13q21) for the right wrist overlapped with major QTLs reported in following multipoint linkage analysis (LOD= 1.7549, LOD=1.4462, respectively). This study provides the possible evidence of the presence of QTLs affecting right wrist BMD in Mongolian populations on 13p11 and 13q21. Modest evidence was also found for genes affecting left ankle and left wrist BMD on 13p13.

In order to get the precise blood pressure and pulse number in the cuffless status, the wrist wearable pulsimeter with a portable and small size apparatus using by Hall device is developed. The regression analysis of the pulse wave measured by the testing product of pulsimeter is conducted two equations of the blood pressure algorithm. The estimated values of blood pressure obtained by the cuffless pulsimeter during 5 s are compared with the practical values measured by electronic or mercury liquid blood pressure meters. The standard deviation of the estimated value and the practical value for the high blood pressure and the low blood pressure were 12.1 and 5.9, respectively, which have the neighborhood values of BP International Standard. The detail analysis of a pulse wave measured by cuffless wrist wearable detecting the changes of the magnetic field can be used to develop a new diagnostic algorithm of blood pressure applying for oriental medical apparatus like as the wrist wearable pulsimeter.

This study was designed to investigate the median nerve cross-sectional area of the upper extremity which is the main cause of CTS in the 20s and 30s. The median nerve cross-sectional area (MNC-area) of each part of the upper limb was measured in healthy 20s and 30s females and males without neurological diseases or other diseases. This MNC-area was compared with the hand, wrist, finger, and other body indexes. The research group was divided into 20s female and male groups, and the 30s were also divided into female and male groups. In the comparison between the ages, the hand, and wrist configurations in the 30s were significantly higher than those of the 20s. The mean median nerve cross-sectional area was significantly larger in the male group than in the female group in both 20s and 30s, and it was larger in both men and women than in the 20s. Hand and wrist configurations were also positively correlated with the median nerve cross-sectional area in both 20s and 30s. The median values of hand ratio and wrist ratio were 2.26 and 0.65, respectively. This median value of hand ratio was inversely correlated with the median nerve cross-sectional area. The median nerve cross-area of the 20s was 6.88~7.38 ㎟ in the male group and 5.69~6.99 ㎟ in the female group, respectively. The median nerve cross-area of the 30s was 6.32~8.89 ㎟ in the male group and 6.15~7.17 ㎟ in the female group, respectively. The mean median nerve cross-sectional area was positively correlated with body mass index in both groups. Most of the variables were higher in their 30s than in their 20s.
