The purpose of this study was to compare the hand disinfection effect of waterless alcohol gel hand washing agent with that of soap and water, 4% chlorhexidine gluconate, and 10% povidone-iodine. Hands of fourty subjects were artificially contaminated with Acinetobacter baumannii $5m{\ell}$ and randomly distributed to each hand washing methods. Samples were collected from gloved hand by glove juice sampling procedure. Mean log reduction after hand washing were compared with baseline values. Number of microorganisms were converted to log and tested by ANOVA in SPSSWIN 10.0. Mean log reduction of soap and water, alcohol gel, 4% chlorhexidine gluconate, 10% povidone-iodine were $2.76{\pm}0.62$, $2.97{\pm}0.56$, $4.66{\pm}1.70$, $4.60{\pm}0.91$, respectively. The bactericidal effect of alcohol gel was similar to that of soap and water, but the effect was much less than chlorhexidine gluconate and povidone-iodine(p<0.001). In terms of microorganism reduction, the efficacy of waterless alcohol gel was almost the same as soap and water hand washing. Further evaluation of the bactericidal effect of waterless alcohol gel is needed because waterless alcohol gel is simple, convenient, and non-irritating hand washing agent and also very effective in busy hospital environment.

Purpose: We tested the inhibitory effect of six purchasable alcohol hand rubs against Staphylococcus aureus. Methods: Five alcohol hand rubs were collected with random manner on the market and 1 alcohol hand rubs which is currently used in a hospital was included. we designed the experimental scheme on the basis of M7-A6 method of NCCLS. Each hand rubs were diluted to 1:1, 1:10, 1:100, 1:1,000 with tryptic soy broth. S. aureus was cultured. Turbidity and the colony counting was measured. Results: With dilution rate of 1:1, all products showed more than 95% of the inhibitory effect on bacterial growth. At 1:10 dilution, product $N^{\circ}1$, 2, 3, 4, and 5 displayed the inhibitory effect of 97.77%, 92.38%, 78.19%, 97.42%, and 96.6%, respectively. But, the inhibitory effect of product $N^{\circ}6$ has been disappeared at that dilution. Over 1:100 dilution, all products lost their inhibitory effect except product $N^{\circ}5$. Product $N^{\circ}5$ displayed more than 96% of inhibitory effect at all dilution rate, even at 1:100 and 1:1,000. Conclusion: We identified that inhibitory effect on bacterial growth of alcohol hand rubs was variable. We suggest that concentration of alcohol should be checked before choosing alcohol hand rubs. Further evaluation of in vivo study is needed.

The purpose of this study was to investigate effect of robot-assisted hand rehabilitation(Amadeo(R)) on hand motor function in chronic stroke patients. This study used a single-subject experimental design with multiple baselines across individuals. Three chronic stroke survivors with mild to sever motor impairment took part in study. Each participants had 2 weeks interval of starting intervention. Participants received robot-assisted therapy(45min/session. 3session/wk for 6wks). Finger active range of motion(AROM) was assessed by Range of Assessment program in Amadeo(R), and test-retest reliability was verified using Pearson correlation analysis. To investigate effect of Amadeo(R), finger AROM was measured immediately after each sessions and Fugl-Meyer Assessment of Upper extremity, Motor Activity Log, Nine hole peg board test and Jebsen-Taylor hand motor function test were assessed at pre-post intervention. Results were analyzed by visual analysis and comparison of pre-post tests. The test-retest reliability of Range of Assessment was good(r=.99). After robot-assisted therapy, finger AROM of participant 1, 2, and 3 was respectively improved by 18%, 3.6%, and 6% each. Hand motor function of participant 1, 3 was improved on all four tests, but not effect in participant 2. Robot-assisted hand rehabilitation could improve finger AROM and effect on hand motor function in chronic stroke patients.

The purpose of this study is to investigate the current status and motives of buying second-hand clothing among university students and to suggest a plan to activate second-hand clothing transactions. In order to discover the effect of the buying motives on the purchasing of second-hand clothing, 112 university students who have purchased second-hand clothing over the past six months were surveyed and their responses were used for analysis. As a result of the analysis, it was found that design differentiation, habitual use, and economical factors had a meaningful effect on the purchase of second-hand clothes. Second-hand clothes have a positive environmental perception, but that perception did not impact the purchasing of second-hand clothes. It is necessary to raise the awareness and social movement around second-hand clothing and teach consumers the environmental benefits and sustainability of second-hand clothing. An activation plan for the second-hand clothing market is: 1. Proposes various market subdivisions that meet the characteristics and tastes of consumers that lead to the purchase of used clothing. In this study, two economic factors were found among the buying motives. The first is purchasing second-hand clothing at a very low price, and the second is finding luxurious expensive items or unique values at a lower price. Therefore, it is necessary to find various markets segments that suit consumer tastes by checking consumer characteristics and detailed factors. 2. Nurture second-hand clothing processing brands for the diversification of the second-hand clothing market. 3. There is an urgent need for quality classification, quality assurance, and the standardization of second-hand clothing. This study is meaningful in that it explored the possibility of having a positive effect on activating the second-hand clothing market.

Purpose: This study was conducted to test the effect of a scenario based hand hygiene education program on hand hygiene knowledge, hand hygiene perception, hand hygiene compliance and hand hygiene method in nursing students. Methods: A non-equivalent control group, non-synchronized quasi-experimental design was used. Forty five nursing students participated in the study with 22 in the experimental group and 23 in the control group. Data were analyzed using descriptive statistics, ${\chi}^2-test$, t-test, and repeated measures of ANOVA. Results: There were significant increases in hand hygiene knowledge (t=-4.28, p<.001) and accuracy of the hand hygiene method by week (F=7.33, p<.001). However, hand hygiene perception (t=-1.67, p=.102) and hand hygiene compliance rate (F=7.33, p=.405) were not significantly changed. Conclusion: The effects of the scenario based hand hygiene education program provided in this study were excellent, compared to the other hand hygiene education programs. Moreover, as a result of investigating the education effects through direct observation for 4 weeks, appropriate feedback was offered in the third week, and it was found that maintaining the effect was necessary. However, the current status of hand hygiene compliance and accuracy of methods for ensuring hand hygiene need to be studied further.
