In order to find out whether Hand Acupuncture Therapy and Moxibustion Heat Therapy is effective to relieve dysmenorrhea syndrome, we performed a Quasi-experiment on a group of fourty females. The experiment was carried out during the period from April 20 to August 20, 1999. The group was divided into two sub-groups called "a Hand Acupuncture Therapy sub-group" and "a Moxibustion Heat Therapy sub-group" consisting of 20 females respectively. Hand Acupuncture Therapy and Moxibustion Heat Therapy were performed four times a week. Especially, in case of Moxibustion Heat Therapy, subjects were treated twice a times. The data analyzed by an SAS program. The results are as follows : 1) Hand Acupuncture Therapy and Moxibustion Heat Therapy are very effective to relieve dysmenorrhea syndrome. This study shows that in case of Hand Acupuncture Therapy sub-group, supposing that mean score of Menorrhalgia before treatment was 7.85, it became low to 4.50 when. subjects suffered the first menstruation and it was 2.50 at the second menstruation, and 1.60 at the third menstruation. In the mean score of Moxibustion Heat Therapy sub-group, Menorrhalgia before treatment was 7.85, it was 5.90 at the first menstruation(p<.05), and 3.00 at the second, and 1.85 at the third menstruation. 2) Among Hand Acupuncture Therapy subgroup, 9 subjects could hardly be relieved from the pain of dysmenorrhea at the first menstruation. So, they were treated additionally with the method of tonification and sedation of abdominal diagnosis of three constitution and became completely relieved at second menstruation. Meanwhile, 7 subjects among Moxibustion Heat Therapy also faced the same situation. So they were treated with Moxibustion on dorsum of hand and got effectiveness at the third menstruation after taking therapy. 3) Odinary dysmenorrhea syndrome are constipation, dizziness, anorexia, abdominal pain, lumbago, breast engorgement, abdominal distention, dysconcentration, nervousness, diarrhea, nausea & vomitting, apathy, restlessness, fatigue, aggression, leg pain, edema. After taking therapy, all of subjects were relieved from these dysmenorrhea syndrome at third menstruation. 4) All subjects were classified into five types of physical constitution with abdominal diagnosis of three constitution as follows: 18 cases of left kidney right yang excess, 8 cases of left yin right yang excess, 7 cases of left right kidney excess, 5 cases of left right yang excess, 2 cases of left yang right kidney excess.

Purpose: This study sought to verify the effectiveness of the Nurse Hand Cream developed to protect the skin of the hands of nurses damaged by frequent hand hygiene. Methods: A randomized controlled trial was conducted that compared the hand skin moisture content of subjects using the Nurse Hand Cream that had been developed for nurses with that of the other hand cream. Results: After applying the hand cream, the subjects' skin moisture content were measured using a skin moisture measuring device; the moisture content of the experimental group significantly increased compared with the control group (p<.001). In particular, as a result of the second experiment that involved the four-time performance of hand hygiene every 30 minutes for two hours, the skin moisture content of the experimental group significantly increased compared with the control group, and 84.4% of the experimental group maintained a normal or higher skin moisture content. Conclusion: The hand cream for nurses was statistically confirmed to strengthen the moisturizing power and prevention of skin moisture loss compared with the other hand cream.

We introduce a vision-based hand gesture recognition fer understanding musical time and patterns without extra special devices. We suggest a simple and reliable vision-based hand gesture recognition having two features First, the motion-direction code is proposed, which is a quantized code for motion directions. Second, the conducting feature point (CFP) where the point of sudden motion changes is also proposed. The proposed hand gesture recognition system extracts the human hand region by segmenting the depth information generated by stereo matching of image sequences. And then, it follows the motion of the center of the gravity(COG) of the extracted hand region and generates the gesture features such as CFP and the direction-code finally, we obtain the current timing pattern of beat and tempo of the playing music. The experimental results on the test data set show that the musical time pattern and tempo recognition rate is over 86.42% for the motion histogram matching, and 79.75% fer the CFP tracking only.

In order to secure pedestrians' right to walk, we have up-cycled second hand mobile phones to overcome limitations of the existing survey methods, analysis methods, and diagnosis to reduce pedestrian traffic accidents. Second hand mobile phones were up-cycled to produce mobile CCTVs and installed in areas where pedestrian deaths rate is high to secure image data sets for the period of more than 24 hours. It was analyzed by applying image visualization technology and clouding reporting technology, and more precise and accurate results were derived through modeling based on artificial intelligence learning and GIS-based diagnostic guidance. As a result, it was possible to analyze the risk factors and number of pedestrian safety, and even factors that were not known in the existing method could be derived. In addition, the traffic accident risk index was derived by converting data into one year to verify whether second hand mobile phone up-cycling mobile CCTV will be an objective tool for finding pedestrian risk factors. Up-cycling mobile CCTV of second hand mobile phones newly applied through research can be used as a new tool to find pedestrian risk factors, and it can be used as a service to protect the safety of the traffic vulnerable other than pedestrians.

Purpose: To compare the leakage and scattered radiation from hand-held dental X-ray unit with radiation from fixed dental X-ray unit. Materials and Methods: For evaluation we used one hand-held dental X-ray unit and Oramatic 558 (Trophy Radiologie, France), a fixed dental X-ray unit. Doses were measured with Unfors Multi-O-Meter 512L at the right and left hand levels of X-ray tube head part for the scattered and leakage radiation when human skull DXTTR III was exposed to both dental X-ray units. And for the leakage radiation only, doses were measured at the immediately right, left, superior and posterior side of the tube head part when air was exposed. Exposure parameters of handheld dental X-ray unit were 70 kVp, 3 mA, 0.1 second, and of fixed X-ray unit 70 kVp, 8 mA, 0.45 second. Results: The mean dose at the hand level when human skull DXTTR III was exposed with portable X-ray unit $6.39{\mu}Gy$, and the mean dose with fixed X-ray unit $3.03{\mu}Gy$ (p<0.001). The mean dose at the immediate side of the tube head part when air was exposed with portable X-ray unit was $2.97{\mu}Gy$ and with fixed X-ray unit the mean dose was $0.68{\mu}Gy$ (p<0.01). Conclusions: The leakage and scattered radiation from hand-held dental radiography was greater than from fixed dental radiography.

Purpose: This study was conducted to test the effect of the Hand Hygiene Education Program on hand hygiene knowledge, hand hygiene perception, nasal Staphylococcus aureus colonization and hand hygiene adherence in nursing students. Methods: A non-equivalent pre-post test of quasi-experimental design was used. 87 second grade nursing students participated in the study with 43 in the experimental group and 44 in the control group. We used the Hand Hygiene Education Program which was held 5 times over 5 weeks, taking 60 minutes per session. For the analysis, descriptive statistics, chi test, and t-test were used for statical analysis with SPSS 19.0. Results: There were significant increases in hand hygiene knowledge (p=.004) and hand hygiene adherence (p=.002) and there was a significant decrease in nasal Staphylococcus aureus colonization (p=.026) in the experimental group compared to the control group. However, hand hygiene perception (p=.543) was not significantly changed. Conclusion: Findings of this study suggest that the Hand Hygiene Education Program may be effective in enhancing hand hygiene knowledge and hand hygiene adherence. Also this program was effective in reducing nasal Staphylococcus aureus colonization in nursing students. Further studies are needed to evaluate the effects of the Hand Hygiene Education Program on hand hygiene perception in nursing students.

In this paper, we propose a new histogram based hand recognition algorithm for augmented reality. Hand recognition system makes it possible a useful interaction between an user and computer. However, there is difficulty in vision-based hand gesture recognition with viewing angle dependency due to the complexity of human hand shape. A new hand recognition system proposed in this paper is based on the features from hand geometry. The proposed recognition system consists of two steps. In the first step, hand region is extracted from the image captured by a camera and then hand gestures are recognized in the second step. At first, we extract hand region by deleting background and using skin color information. Then we recognize hand shape by determining hand feature point using histogram of the obtained hand region. Finally, we design a augmented reality system by controlling a 3D object with the recognized hand gesture. Experimental results show that the proposed algorithm gives more than 91% accuracy for the hand recognition with less computational power.

The advanced techniques for video processing and computer graphics enables a sign language education system to appear. the system is capable of showing a sign language motion for an arbitrary sentence using the captured video clips of sign language words. In this paper, a method is suggested which generates the frames between the last frame of a word and the first frame of its following word in order to animate hand motion. In our method, we find hand locations and angles which are required for in between frame generation, capture and store the hand images at those locations and angles. The inbetween frames generation is simply a task of finding a sequence of hand angles and locations. Our method is computationally simple and requires a relatively small amount of disk space. However, our experiments show that inbetween frames for the presentation at about 15fps (frame per second) are achieved so tat the smooth animation of hand motion is possible. Our method improves on previous works in which computation cost is relativey high or unnecessary images are generated.

Purpose: The first purpose of this study was to evaluate whether hand muscle fatigue alters sensorimotor control of the hand in healthy subjects, using hand position sense. The second objective was to assess the repositioning variables during a 7.5-min period after the fatigue protocol. Methods: Participants performed a repeated handgrip movement to induce the fatigue condition as fast as possible, until they could no longer continue. Recordings were performed before (pre-fatigue) and after the completion of the fatigue exercises (immediately: post-fatigue, after a 2.5 min recovery, after a 5 min recovery and after a 7.5 min recovery). Results: The joint reposition test of the MP joint in the post-fatigue condition showed higher reposition errors than the prefatigue condition (p<0.05). Additionally, there was a significant difference in recovery of joint reposition errors after fatiguing exercises of the hand muscle, among groups (p<0.05). Conclusion: The fatigue of the hand muscles affected joint position sense by an alteration of somatosensory and proprioceptive information. Nonetheless, the effect of hand muscle fatigue was short-lived, since joint reposition errors decreased to post-fatigue values after 7.5 min of recovery.
