The purpose of this study was to identify the effect of hand acupuncture for reduction of dysmenorrhea. 71 female middle school and high school students were selected as subjects from April to May 2001, among which 38 students consisted of the experimental group while 22 students were the control group by convenient assignment. The experimental group participated in hand acupuncture treatment. The experimental treatment was to puncture corresponding points(A4, A5, J1, J3, J23, H2, F7) on both the palm and back of a hand with disposable acupuncture needles and to remove needles after 20-30 minutes' recess during which the subjects reposed themselves on bed. The collected data were processed using the SPSS PC Program and analyzed using $X^2test$ and The results of this study were as follows 1. The symptoms of premenstrual syndrome have decreased, but no significant differences were statistically observed between hand-acupunctured group and non-hand acupunctured group. 2. Subjective pain degree has decreased after hand acupuncture. 3. As for objective pain degree, a significant reduction in voice change was observed between two groups. Facial expressional changes and perspiration degree reduced but showed no significant statistically changes between two groups. 4. Comfort has increased after hand acupuncture. These results suggest that the hand acupuncture therapy works effectively on easing menstrual pain and symptoms as well as partially on reducing discomfort. It is particularly efficacious for a reduction in subjective pain and facial expressional changes in positive respect. Therefore the hand acupuncture therapy can be considered as an independent nursing intervention for dysmenorrhea reduction.

We propose a hand gesture recognition method that is compatible with a head-up display (HUD) including small processing resource. For fast link adaptation with HUD, it is necessary to rapidly process gesture recognition and send the minimum amount of driver hand gesture data from the wearable device. Therefore, we use a method that recognizes each hand gesture with an inertial measurement unit (IMU) sensor based on revised correlation matching. The method of gesture recognition is executed by calculating the correlation between every axis of the acquired data set. By classifying pre-defined gesture values and actions, the proposed method enables rapid recognition. Furthermore, we evaluate the performance of the algorithm, which can be implanted within wearable bands, requiring a minimal process load. The experimental results evaluated the feasibility and effectiveness of our decomposed correlation matching method. Furthermore, we tested the proposed algorithm to confirm the effectiveness of the system using pre-defined gestures of specific motions with a wearable platform device. The experimental results validated the feasibility and effectiveness of the proposed hand gesture recognition system. Despite being based on a very simple concept, the proposed algorithm showed good performance in recognition accuracy.

One of the major advantages of microsurgical reconstruction for defects of the hand is that these techniques allow for selection of the most ideal tissue to reconstruct a particular defect, thus optimizing the functional and aesthetic outcome. The dorsalis pedis free flap is an excellent reconstructive tool for various hand reconstructions. It has a reliable vasculature with vessels that are relative large on a long pedicle. It provides thin pliable tissue and be innervated by deep peroneal nerve. Coupled with its thinness and pliability, it is ideal for innervated cover of critically sensitive area, especially such as the hand. Thus it can be used as a cutaneotendinous flap, or an osteocutaneous flap. Otherwise, the major criticism with this flap is related to its uncertain vascularity and the donor defect. It is the purpose of this paper to outline our technique of flap elevation and donor site closure and to indicate our current use of this flap in hand reconstruction. We have treated 10 cases (6 burn scar contracture cases, 4 acute hand trauma cases) of hand reconstruction from Dec. 3, 1997 to Mar. 4, 2004 using dorsalis pedis free flap. The key points for sucess in terms of a viable flap and acceptable donor site are the preservation of the critical dorsalis pedis-first dorsal metatarsal vascular axis and the creation of a viable bed for grafting. In addition, we substituted preserved superficial fat skin graft for split thickness skin graft and wet environment was offered for good graft take. Preserved superficial fat skin is defined as composite graft containing epidermis, dermis and superficial fat layer. With sufficient care in flap elevation and donor site closure, a good graft take of preserved superficial fat skin under wet environment can be achieved with no functional disability and minimal cosmetic deformity in donor site. This flap has proved itself to be a best choice for hand reconstruction.

Purpose: The purpose of this study was to compare the 1% chlorhexidine gluconate/61% ethanol (CHG/ethanol), 45% ethanol/18% 1-propanol (ethanol/propanol) and 7.5% povidone-iodine (PVI) scrub with brush to evaluate their antimicrobial effect. Method: Utilizing repeated measures design, 9 nurses participated in the study. Glove juice sampling procedure was used to evaluate microbial hand counts before the surgical hand antisepsis, one minute after hand wash, and after the surgery. Results: Waterless rub using CHG and ethanol combination resulted in a 3.94 log reduction at 1 min and 2.78 log reduction at 3 hrs. Ethanol/propanol resulted in a 2.42 at 1 min and 2.22 at 3 hrs. The traditional scrub using PVI with brush resulted in a 0.94 at 1 min and 0.95 at 3 hrs (p=.003) and 3 hrs (p=.026) after the surgical hand antisepsis. Repeated measures ANOVA results showed that there was a statistically significant difference among group (p=.002). Duncan post hoc test result showed that the PVI was less effective (p<.05) in sterilizing microbials on hands than CHG/ethanol or ethanol/propanol. Conclusion: Both of the two alcohol-based antiseptic rubs are acceptable alternatives to the PVI with brush for surgical hand antisepsis.

In this paper, a three-fingered anthropomorphic robot hand, called SKK Robot Hand 1, is presented. By employing a two-DOF joint mechanism, called Double Active Universal Joint (abbreviated as DAUJ from now on) as its metacarpal joint, the hand makes it possible to mimic humanlike motions. We begin with addressing the motivation of the design and mention how the anthropomorphic feature of a human is realized in the design of SKK Hand I Also, the mechanism of the hand is explained in detail, and advantages in its modular design are discussed. The proposed hand is developed for use as a testbed for dextrous manipulation. It is expected to resolve the increasing demand for robotic applications in unstructured environments. We describe its hardware construction as well as the controller structure including the preliminary results of experiments.

Objective : Rheumatoid arthritis (RA) is a systemic disease that can affect the cervical spine, especially the atlantoaxial region. The present study evaluated the risk factors for atlantoaxial subluxation (AAS) development and progression in patients who have undergone surgical treatment. Methods : We retrospectively analyzed the data of 62 patients with RA and surgically treated AAS between 2002 and 2015. Additionally, we identified 62 patients as controls using propensity score matching of sex and age among 12667 RA patients from a rheumatology registry between 2007 and 2015. We extracted patient data, including sex, age at diagnosis, age at surgery, disease duration, radiographic hand joint changes, and history of methotrexate use, and laboratory data, including presence of rheumatoid factor and the C-reactive protein (CRP) level. Results : The mean patient age at diagnosis was 38.0 years. The mean time interval between RA diagnosis and AAS surgery was $13.6{\pm}7.0$ years. The risk factors for surgically treated AAS development were the serum CRP level (p=0.005) and radiographic hand joint erosion (p=0.009). The risk factors for AAS progression were a short time interval between RA diagnosis and radiographic hand joint erosion (p<0.001) and young age at RA diagnosis (p=0.04). Conclusion : The CRP level at RA diagnosis and a short time interval between RA diagnosis and radiographic hand joint erosion might be risk factors for surgically treated AAS development in RA patients. Additionally, a short time interval between RA diagnosis and radiographic hand joint erosion and young age at RA diagnosis might be risk factors for AAS progression.
