Objectives : This study was designed to evaluate the effect of moving cupping therapy on the edema of paretic hand in stroke patients. Methods : The subjects were stroke patients with flaccid hemiplegia. Each subject's routine therapy program was maintained throughout single subject ABAB design. During the first week, baseline data were gathered. During the second and fourth week, intervention was provided(total 20minutes of moving cupping therapy, from contralateral to ipsilateral, distal to proximal). During third and fifth week, data were gathered with treatment withdrawn. Edema was measured with hand volumeter and measuring tape. Basically Bayesian analysis was performed using WinBUGS(ver. 1.4), for addition, visual graph and mean score were also presented for comparison between treatment(moving cupping therapy) and non-treatment. Results : The visual graph and mean score showed decrease in edema during the treatment weeks. Overall decrease in edema by moving cupping therapy was verified significantly by using Bayesian ana-lysis(95% credibility intervals). Conclusions : This study suggests that moving cupping therapy could be applicable for reducing post-stroke hand edema. Further research would be needed to establish guidelines for use.

In this paper, we develop face and hand tracking for sign language recognition system. The system is divided into two stages; the initial and tracking stages. In initial stage, we use the skin feature to localize face and hands of signer. The ellipse model on CbCr space is constructed and used to detect skin color. After the skin regions have been segmented, face and hand blobs are defined by using size and facial feature with the assumption that the movement of face is less than that of hands in this signing scenario. In tracking stage, the motion estimation is applied only hand blobs, in which first and second derivative are used to compute the position of prediction of hands. We observed that there are errors in the value of tracking position between two consecutive frames in which velocity has changed abruptly. To improve the tracking performance, our proposed algorithm compensates the error of tracking position by using adaptive search area to re-compute the hand blobs. The experimental results indicate that our proposed method is able to decrease the prediction error up to 96.87% with negligible increase in computational complexity of up to 4%.

This study analyzed the knit wear trend, which has gained attention as a sensuous and luxury item, through collection magazines, and used the technique of hand-knit to produce and present the knit wear that was designed based on the study results. Accordingly, the purpose of this study is to raise awareness of the expansion of hand knit's new expression techniques and expression areas and to verify its possibility as a higher value-added product. The trends of hand-knit wear resulted from the analysis of collections divided into the following four groups, and the knit designs were also grouped accordingly: First was "The design using object." The trend survey showed the results that the form of drops or flowers was often used as a factor of object. Accordingly, as for the study design, the drop-knitting technique, which is one of the pattern knitting techniques, was used to present a design that employed drops as the object. Second was "The design matched with woven material." It is a way to emphasize aesthetic formativeness and at the same time to activate the area of knit design by matching woven material, which is different from knit in texture, with knit. This study presented a design that tried to combine knit texture and woven material by connecting denim material with various textures and colors. Third was "The design to express see-through." A sense of showing through knit wear was expressed through changes in the type of thread or knitting technique. In this study, the sense of see-through was expressed using piano wires and wool threads and through changes in the thickness of needle. Fourth was "The design to emphasize coloring." It was analyzed that regarding the production of hand knit, the method of coloring expression was to express points, lines and sides or to create harmony by changing the material's color or texture to show particular objects or shapes. In this study, a jacket was designed using the method to express points, lines and sides by changing the material's color.

Purpose: This study examined the effects of training using the slime on the hand function and problem behavior in adults with intellectual disabilities. Methods: Five adults with intellectual disabilities who were judged as Level 1 or Level 2 were selected. The training consisted of one session (50 min)/day, one day/week for 10 weeks (preparatory activities: 5 min, slime activities: 40 min, finishing activities: 5 min) The functions of the hand (Purdue Pegboard Test [PPT], grip strength test [GST]) and problem behavior (Korean Behavior Problems Inventory [KBPI]) were assessed three times (first assessment; pre, second assessment; post-5 weeks, third assessment; post-10 weeks). Wilcoxon signed-rank tests were used to analyze changes in the subjects' performance before and after the intervention. Results: In the PPT, the use of the non-dominant hand was increased significantly (p<0.05). No significant differences were observed in the remaining results, but the mean value increased. In addition, although the problem behavior was not statistically significant, an increase in the problem behavior score was noted. Conclusion: The training using the slime for adults with intellectual disabilities is effective in hand function improvement and reducing problem behavior.

Objectives : The aim of this study is to summarise pattern-identification of shoulder pain based on the classics of oriental medicine, current literature and domestic papers. Methods : The materials selected were sourced from the classics of oriental medicine, current literature and domestic papers which contained data related to pattern-identification of shoulder pain. The pattern-identifications were compared to determine the similarities, and these were classified. Results : Thirty-five studies were reviewed, and thirty-seven pattern-identifications were collated. These were classified into the following groups: wind-cold-dampness group(n = 8), blood stasis group(n = 3), phlegm group(n = 7), dual deficiency of Qi and blood group(n = 4), deficiency cold group(n = 2), liver-kidney deficiency group(n = 1) and meridian-collateral group(n = 12). Conclusions : On the basis of the classification of pattern-identifications, two groups of pattern-identifications for shoulder pain were suggested. The first group included the pattern-identification associated with a disease-cause, which included the wind-cold-dampness pattern(風寒濕型), blood stasis pattern(瘀血型), phlegm pattern(痰飮型), Qi-blood deficiency pattern(氣血兩虛型), deficiency cold pattern(虛寒型), and liver-kidney deficiency pattern(肝腎虧損型). The second included the pattern-identification associated with the meridian-collateral, which included the hand greater Yin meridian pattern(手太陰經型), hand Yang brightness meridian pattern(手陽明經型), hand lesser Yin meridian pattern(手少陰經型), hand greater Yang meridian pattern(手太陽經型), hand reverting Yin meridian pattern(手厥陰經型), hand lesser Yang meridian pattern(手少陽經型), and foot greater Yang meridian pattern(足太陽經型).

A GUI (graphical user interface) has been a dominant platform for HCI (human computer interaction). A GUI - based interaction has made computers simpler and easier to use. The GUI - based interaction, however, does not easily support the range of interaction necessary to meet users' needs that are natural. intuitive, and adaptive. In this paper, the modified BMA (block matching algorithm) is proposed to track a hand in a sequence of an image and to recognize it in each video frame in order to replace a mouse with a pointing device for a virtual reality. The HCI system with 30 frames per second is realized in this paper. The modified BMA is proposed to estimate a position of the hand and segmentation with an orientation of motion and a color distribution of the hand region for real - time processing. The experimental result shows that the modified BMA with the YCbCr (luminance Y, component blue, component red) color coordinate guarantees the real - time processing and the recognition rate. The hand tracking by the modified BMA can be applied to a virtual reclity or a game or an HCI system for the disable.

Using Bi-Digital O-Ring Test which was developed by Ohmura Toshiaki, constiution classification by the vegetables' was Measured by various muscle power measurement meters and the results are as follow: 1. Pinch Gauge (Model:pc5030HPG, Japan) is the gauge to measure finger power between the thumb and the second finger, Grip Strength Dynamometer (Model: T.K.K. 5101, Japan) is to measure the hand power (hand dynamometer), Back Strength Dynamometer (Model: T.K.K. 5102, Japan) is to measure back muscle strength, Vertical jump Meter (Model: T.K.K. 5106, Japan) is to measure the height of jump. The above gauges were and its result found that the radish, potato, carrot and cucumber can influence to muscle strength was not true. 2. When the physical constitution is distinguished by the O-Ring Test method, Taeyangin's rate appeared as average 21% although it was insisted that there will be only 0.03-0.1%. This means that the physical constitution but it appears accidently according to the examinee's emotion about the material such as vegetable etc. as favor or unfavor. 3. It was found that the result of O-Ring Test is the same at any time and at any place was not true. there is no reemergence character. 4. The import of O-Ring Test mehtod to the physical discrimination disregarded that the mental factor influences absolutely to the physical heath in the ideological physi cal constitution medical science. 5. 'O-Ring Test method is a objective judgement method.' is wrong judgement. As you see on the above result, Bi-Digital O-Ring Test set the changeable voluntary muscle as the standard of the judgument, that was first mistake logically, second in spite of leass influence of mental influence by the examiner and examinee than the vegetable discrimination influence, the test disregarded the influence. Third, only grasp of some material on hand can influence to the voluntary muscle was a wrong theory disregarding the physiology. Finally the misunderstaning his subjective view as an objective view in spite of examiner and examinee's strong influence. Therefore such kind of physical descrimination method must be sublated.

The lumbrical muscles contribute to the intrinsic plus position, that is simultaneous metacarpophalangeal (MCP) flexion and interphalangeal (IP) extension. The strength of the lumbrical muscles is necessary for normal hand function. However, there is no objective and efficient method of strength measurement for the lumbrical muscles. In addition, previous studies have not investigated the measurement of the cross-sectional area (CSA) of the lumbrical muscles using ultrasonography (US) and the relationship between lumbrical muscle strength in the intrinsic plus position and the CSA. Therefore, the purpose of this study was to identify the measurement method of the CSA of the lumbrical muscles using US and to examine the relationship between maximal isometric strength and the CSA of lumbrical muscles. Nine healthy males participated in this study. Maximal isometric strength of the second, third, and fourth lumbrical muscles was assessed using a tensiometer in the intrinsic plus position which isolated MCP flexion and IP extension. The CSA of the lumbrical muscles was measured with an US. The US probe was applied on the palmar aspect of the metacarpal head with a transverse view of the hand in resting position. There was no significant difference between maximal isometric strength of the lumbrical muscles, but the fourth lumbrical muscle was stronger than the others. The CSA of the lumbrical muscles was significantly different and the fourth lumbrical muscle was significantly larger than the second lumbrical muscle. There was moderate to good correlation between maximal isometric strength and the CSA of the lumbrical muscles. Therefore, we conclude that maximal isometric strength of the lumbrical muscles was positively correlated to the CSA of the lumbrical muscle in each finger, while the measurement of the CSA of the lumbrical muscles, using US protocol in this study, was useful for measuring the CSA of the lumbrical muscles.

In this paper, we propose a hand tracking and gesture recognition system. Our system employs a depth capture device to obtain 3D geometric information of user's bare hand. In particular, we build a flexible tracking volume and restrict the hand tracking area, so that we can avoid diverse problems caused by conventional object detection/tracking systems. The proposed system computes running average of the hand position, and tracking volume is actively adjusted according to the statistical information that is computed on the basis of uncertainty of the user's hand motion in the 3D space. Once the position of user's hand is obtained, then the system attempts to detect stretched fingers to recognize finger gesture of the user's hand. In order to test the proposed framework, we built a NUI system using the proposed technique, and verified that our system presents very stable performance even in the case that multiple objects exist simultaneously in the crowded environment, as well as in the situation that the scene is occluded temporarily. We also verified that our system ensures running speed of 24-30 frames per second throughout the experiments.
