Objectives : The purpose of this study was to examine influential factors related to hand washing practice in dental hygienists by health belief model, one of the major predictors of health behavior including perceived susceptibility, perceived seriousness, perceived benefits, perceived barriers and cues to action. Methods : The subjects were dental hygienists in dental hospitals, dental clinics, general hospitals and university hospitals in Seoul. A survey was conducted from May 1 to September 30, 2011. Results : Analysis of health belief of dental hygienists in hand washing, they revealed the highest marks of 4.39 to perceived benefits, followed by perceived susceptibility(4.29), perceived seriousness(3.94), cues to action(3.30) and perceived barriers(1.81). The mean was 4.13 in hand washing practice. The senior and well educated dental hygienists in general hospitals had a tendency to wash hands frequently. It is statistically significant(p<0.05). In regard to the correlation among the subfactors of health beliefs, susceptibility had a statistically significant positive correlation to seriousness, benefits and cues to action, and seriousness was positively correlated to benefits and cues to action. Conclusions : It is necessary to develop and implement hand washing education program for dental hygienists focusing on perceived benefits and barriers which are two of the health beliefs affecting the hand washing practice.
Background One-per-mil tumescent solution, which contains 0.2% lidocaine with 1:1,000,000 epinephrine, has been reported to be clinically effective for hand surgery under local anesthesia. However, it was lacking in its basic pharmacokinetics profile in regard to the onset of action (OOA) and duration of action (DOA). Methods A randomized, double-blind study was conducted on 12 volunteers who met the inclusion criteria from October to November 2014. All volunteers had their right and left ring finger pulps injected with either one-per-mil solution or 2% lidocaine. Semmes-Weinstein and two-point discrimination tests were used to test sensation. Visual analogue scale was recorded at the time when the finger lost its sensation and when it regained normal sensation to measure the OOA and DOA. The data were then analyzed with a paired t-test and a Wilcoxon signed-rank test. Results The OOA and DOA of 2% plain lidocaine were 1 minute and 99.67 minutes, respectively. Meanwhile, 0.2% lidocaine in a one-per-mil tumescent solution showed an OOA of 5 minutes and a DOA of 186.83 minutes. The OOA of 0.2% lidocaine in a one-per-mil tumescent solution is statistically shorter than 2% plain lidocaine (P=0.04); while its DOA is statistically longer than 2% plain lidocaine (P<0.001). Conclusions The 0.2% lidocaine in a one-per-mil tumescent solution is statistically and clinically superior to 2% plain lidocaine in achieving longer duration of local anesthesia.
This study focused on hand sanitizer as a medium that can replace ultrasonic gel, which is vulnerable to contamination by bacteria that reside on the hand. Hand sanitizer produces a strong sterilization effect from germs resident on the hands through different sterilization principles depending on the ingredients. Select products of gel type, cream type, and foam type, except for liquid type with low viscosity, and ultrasonically apply one 62% ethanol gel type and one cream type, one benzalkonium chloride 0.066% cream type and one foam type, respectively. Using ATS-539 as a medium, image evaluation was performed on the axial and lateral resolution and penetration depth, and the presence or absence of an air layer between the probe and the phantom. As a result, in the evaluation of the axial and lateral resolution and the depth of penetration, all four experimental groups met the evaluation criteria. However, in the case of the foam type, although it was suitable for the evaluation criteria of resolution and penetration depth, dark shadows appeared on both sides except for the center of observation during image evaluation. Through this experiment, it was possible to confirm the possibility that the remaining three types of hand sanitizers except the foam type could replace the ultrasonic gel.
The purpose of this study was to exame the effectiveness of the hand massage as an independent nursing intervention for the cancer patients undergoing radiation therapy. The data were collected with quasiexperimental research design from 40 subjects-20 for experimental group and 20 for control group-of the radiation oncology department of one university hospital in Seoul from January 10th to March 29th, 1994. Subjects agreed to participate in this study and ranged in age from 18 to 82 years with mean age of 52.63. They had insight of their disease and had undergone radiotherapy at least twice. The hand massage developed by Mariah Snyder (1993) based on the Swedish Massage was administered to the experimental group prior to having radiation therapy at the waiting place of radiotherapy room. Hand massage was given to each hand of patient for five minutes once a day. Measurement of the patient's blood pressure, pulse rate, state anxiety and mood were done before and after the administration of hand massage for 5 days. The data were analyzed with paired t-test, t-test an4 the results were summarized as follows ; 1. After administration of the hand massage, the diastolic blood pressure of experimental group was decreased significantly, while the systolic blood pressure and the pulse rate were decreased, but not significantaly. 2. In the experimental group, the level of anxiety was significantaly lower than control group. The mean scores of the difference of the anxiety level after having hand massage was 8.60 in the experimental group and 0.75 in the control group. 3. The difference of the mood scores before and after the massage in the experimental group was decreased significantly. The mean mood score was decreased 4.80 in the experimental group as compared with 2.02 in the control group. 4. The patients after having the hand massage expressed subjectively their feeling of relaxation, well - being and being enjoyable, the significant decreased of physical symptoms and anxiety. The findings summarized that the use of the hand massage for the cancer patient undergoing radiation therapy Produced significant changes in the level of anxiety and relaxation. Therefore it is recommended to use the hand massage as an intervention for the patients.

Background Hand strength deficit following digital replantation is usually attributed to the mechanical deficiency of the replanted digit. Zone 1 replantation, however, should not be associated with any mechanical deficit, as the joint and tendon are intact. We evaluate shortterm motor functions in patients who have undergone single-digit zone 1 replantation. Methods A single-institution retrospective review was performed for all patients who underwent zone 1 replantation. Hand and pinch strengths were evaluated using standard dynamometers. Each set of measurements was pooled according to follow-up periods (within 1 month, 1 to 2 months, 2 to 3 months, and after 3 months). The uninjured hand was used as reference for measurements. Results The review identified 53 patients who had undergone zone 1 replantation and presented for follow-up visits. Compared to the uninjured hand, dynamometer measurements revealed significantly less strength for the hand with replanted digit at one month. The relative mean grip, pulp, and key pinch strength were 31%, 46%, and 48% of the uninjured hand. These three strength measurements gradually increased, with relative strength measurements of 59%, 70%, and 78% for 4-month follow up. Conclusions Despite the lack of joint or tendon injury, strength of the injured hand was significantly lower than that of the uninjured hand during the 4 months following replantation. Improved rehabilitation strategies are needed to diminish the short-term negative impact that an isolated zone 1 replantation has on the overall hand strength.

As various interfacing devices for computational machines are being developed, a new HCI method using hand motion input is introduced. This interface method is a vision-based approach using a single camera for detecting and tracking hand movements. In the previous researches, only a skin color is used for detecting and tracking hand location. However, in our design, skin color and shape information are collectively considered. Consequently, detection ability of a hand increased. we proposed primary orientation edge descriptor for getting an edge information. This method uses only one hand model. Therefore, we do not need training processing time. This system consists of a detecting part and a tracking part for efficient processing. In tracking part, the system is quite robust on the orientation of the hand. The system is applied to recognize a hand written number in script style using DNAC algorithm. Performance of the proposed algorithm reaches 82% recognition ratio in detecting hand region and 90% in recognizing a written number in script style.

Purpose: Purpose of this study was to identify factors affecting the performance of hand hygiene by parents of hospitalized infants. Methods: The study was conducted with 209 parents of hospitalized infants from one hospital in Changwon. Data were collected from June through August, 2014 and analyzed using SPSS Win 18.0 program. Results: There were positive correlations between performance of hand hygiene and perceptions of sanitary formula bottle (r=.586, p<.001), attitude to hand hygiene (r=.438, p<.001), and knowledge of hand hygiene (r=.405, p<.001) and between parent efficacy and perceptions of sanitary formula bottle (r=.572, p<.001). Awareness of perceptions of sanitary formula bottle (${\beta}$=.308, p<.001), parent efficacy (${\beta}$=.281, p<.001) and hand hygiene attitude (${\beta}$=.207, p<.001) were significant predictors of hand hygiene performance and explained 46.1% of the variance. Conclusion: To increase infection control medical institutions should provide education on hand hygiene and training for parents of hospitalized infants. In order to enhance the performance of hand hygiene, it is necessary to develop and apply nursing programs for hospitalized infants that include hand hygiene attitude, maintenance of the sanitary formula bottle and parent efficacy.

This paper deals with a similarity decision method between the shape of hand-postures and their structures to improve performance of the vision-based hand-posture recognition system. Hand-posture recognition by vision sensors has difficulties since the human hand is an object with high degrees of freedom, and hence grabbed images present complex self-occlusion effects and, even for one hand-posture, various appearances according to viewing directions. Therefore many approaches limit the relative angle between cameras and hands or use multiple cameras. The former approach, however, restricts user's operation area. The latter requires additional considerations on the way of merging the results from each camera image to get the final recognition result. To recognize hand-postures, we use both of appearance and structural features and decide the similarity between the two types of features by learning.

Introduction: The hand and wrist are particularly susceptible to electrical burn. Skin defect with damage or exposure of underlying vital structure requires coverage by skin flap especially in case of the need for late reconstruction. We are reporting 4 cases of electrical burned hand treated by posterior tibial arterial free flap. The commonly used skin flaps such as scapular flap or groin flap are too bulky so that they are not satisfactory in function and cosmetic appearance. So we tried to cover them with a more thin skin flap. Materials and Method: From January 2002 to June 2003, four cases of hand and wrist electrical burn were covered using posterior tibial arterial free flap. All the cases were due to high voltage electrical burn. Age ranged from 31 years to 38 years old and all the cases were male patients. Recipient sites were 2 wrist, one thenar area and one knuckle of 2.3rd MP joint. Additional procedures were flexor tenolysis (simultaneous), FPL tenolysis and digital nerve graft (later) and extensor tendon reconstruction (later). Result: All the flap have survived totally without any complication including circulatory concern about the donar foot. Posterior tibail arterial free flap was so thin that debulking procedure was not required. Conclusion: For skin coverage of the hand & wrist region, posterior tibial arterial free flap have many advantages such as reliable anatomy, easy dissection and easy anastmosis with radial or ulnar artery and possibility of sensory flap. The most helpful advantage for hand coverage is its thinness. So we think this flap is one of the very useful armamentarium for reconstructive hand surgery.
This paper proposes a advanced representation method of hand motion by cheremes analysis in korean sign language. The proposed method is the representation method which apply to the hand motion used in KSL(Korean Sign Language) to represent rich and united hand motion. Words or sentences in KSL are completed by combination of elements called as Cheremes, that is, a hand movement orientation, a finger shape, a hand position, etc. In this paper, Cheremes composing the KSL is divided and represented by 5 elements: the hand movement orientation(HMO), finger shape(FS), hand orientation(HO), hand position(HP) and number of using hand (HN). Each cheremes is expressed by more various characteristics. For example, The hand movement orientation means orientations which the hand move while the sign language is done and can be expressed by 17orientation components. The finger shape means various shapes which fingers can take and represented by 17 components. The Orientation of hand is expressed by 2 characteristics according to whether we use the palm of the hand or the back. The position of hand means specific regions in body which hand(s) is placed while the sign language is done and divided by 8 regions. Finally, the number of hand means whether use only one hand or both hands and is expressed by 2 characteristics. The proposed method has been tested with KSL words and sentences and the results have shown that they can be expressed completely by the proposed representation method.
