Purpose: The purpose of this study was to compare 1% chlorhexidine-gluconate/61% ethanol (CHG/Ethanol) emollient and 7.5% povidone-iodine (PVI) scrub for antimicrobial, residual effect, and skin condition. Method: CHG/Ethanol emollient hand hygiene was performed waterless, and brushless by operating doctors and nurses (N=20). PVI hand washing was performed with water and a brush (N=20) for 5 min. The subjects were asked to press their left hand in hand-shaped agar before a surgical scrub, immediately after a surgical scrub and after the operation. The amount of isolated microorganisms were calculated by counting the number of divided areas($1{\times}1cm$, 160 cell) which were culture positive in the hand culture plate. The skin condition was evaluated. Result: The antimicrobial count of CHG/Ethanol emollient and PVI immediately post surgical scrub was 0.0 vs. 4.1 (p>.05), and after the operation was 0.1 vs. 37.8 (p>.05)respectively. The Residual effect of CHG/Ethanol emollient immediately post surgical scrub and after the operation were 0.0 vs. 0.1 (p>.05), and PVI were 4.1 vs. 37.8 (p>.05)respectively. The skin condition and satisfaction of CHG/Ethanol emollient was higher than PVI (p<.05). Conclusion: The antimicrobial effect between CHG/Ethanol emollient and PVI were the same. Considering skin condition, satisfaction and allergic reaction CHG/Ethanol emollient for surgical scrub is recommended in Korea.

This meta-analysis systematically reviewed studies on mirror therapy focused on arm and hand function in stroke patients, aiming to comprehensively assess the efficacy of mirror therapy interventions and furnish empirical support for its potential application and future development in the context of stroke rehabilitation. A rigorous search for articles published in international journals up to the year 2022 was conducted. Various assessment tools were employed to calculate effect sizes, evaluating the impact of mirror therapy on arm and hand function in stroke patients. Utilizing a random-effects model, mean effect sizes were determined, yielding a total effect size of 0.545. The effect sizes for the Brunnstrom Recovery Stage (BRS), Box and Block Test (BBT), Modified Barthel Index (MBI), Fugl-Meyer Assessment (FMA), and grip strength test were 0.957, 0.596, 0.490, 0.488, and 0.417, respectively. In summary, we suggest that mirror therapy engenders positive changes in functional recovery among stroke patients, establishing a foundation for its tailored clinical application based on individual subject characteristics.

The agitation of dementia patient is a factor which aggravates the care-givers' burdon, and it is needed to develop intervention methods. Hall and Buckwalter hypothesized that an increase in agitation behavior occur when persons experience high levels of stress. This study was conducted to explore the efficacy of hand massage in producing relaxation and decreasing agitation behaviors in persons with dementia. Hand massage was administered once a day in afternoon for 8days to 24 patients and 4days to 23 patients. There was no difference in result between the two groups. Significant differences were found in systolic blood pressure, pulse rate, emotional state from pre to post -intervention with the use of hand massage. The change of systolic blood pressure was 26% explained by ADL, MMSE-K and institutionalized period. The most significant variable was institutionalized period. The change of diastolic blood pressure was 11% explained by ADL, and it was significant. But no decrease in agitation behavior was observed and no increase in functional capacity.

The subjective hand and preference of alkaline hydrolized polyester fabrics were evaluated using the scale developed. The factors affecting consumer's taste for polyester fabrics was analyzed by the statistical technique. The effects of alkaline hydrolysis on the properties of polyester fabrics were evaluated by subjective and objective hand measurements. The lower the age the more senstive their feeling. As the age of evaluators decreased they felt fabrics light flexible refined thin flossy smooth fine soft more clinging. They also thought fabrics are colder, more flexible more spongy as the age increased. Experts were more sensitive and consistent when they evaluation the hand of fabrics than non-experts.

전방투사형 인터랙티브 디스플레이에서는 프로젝터의 빔이 사용자의 손이나 몸에도 투사되는 특성으로 인해 보편적 칼라 추져 기법을 통한 맨 손 영역의 검출이 어렵다. 본 논문에서는 원본 영상의 칼라가 카메라 영상으로 포착되기까지 칼라의 변환 관계를 분석하여 결과를 추정함으로써, 기대치와의 차이 영역 계산을 통해 손 영역을 검출하였다. 이 때, 기존 논문의 부정확한 칼라 추정을 보완하기 위해, 프로젝터와 카메라 반응 값의 칼라 채널별 간섭현상 및 투사된 프레임 내부의 밝기 오차를 룩업테이블로 모델링 하고 맨 손 영역에 대해 유동적인 밝기 차 임계치를 적용하여 정확도를 개선하였다.

본 논문은 원격협업 시스템에서 시각적 의사소통 도구인 눈 시점 포인터 공유의 장점을 알아보았다. 특히 원격 협력자의 손동작이 가상 손으로 공유될 때, 추가로 공유된 원격 협력자의 시점 포인터가 미치는 영향을 조사하였다. 24명의 피실험자가 참여한 사용자 실험에서, 추가된 원격 협력자의 눈 시점 포인터는 현지 협력자와 원격 협력자 모두의 작업 부하를 줄여주었으며 두 협력자 간 co-presence를 높여주었다.

In light-weight hand tools, static posture may result in postural fatigue. Psotural tremor of the upper extremity in a static posture was measured to provide guidelines for hand tool weight. Postural tremor was measured on five levels of tool weitht : no weight, 400g, 800g, 1200g, and 1600g. Three types of camcorder recording postures were selected. For each condition, postural tremor was measured together with ENG of biceps, deltoid and pectoralis major, and Borg's CR-20 ratings of perceved exertion. Results of the experiment are as follows : frequency analysis of tremor revealed increased amplitude of frequency bands of 2-4Hz and 10-14Hz. Postural tremor of the upper extremeity maintained the initial level until fatigue developed. After the development of fatigue, the rate of change of postural tremor significantly increased. Different tool weights and hand postures showed different rates of tremor increase. Time tp fatigue and corresaponding endurance time were positively correlated with Borg's RPE scores.

Growth in the second-hand clothing (SHC) market has become noteworthy, especially for millennial consumers in Korea. This study identifies the moderating role of fashion leadership influencing the relationship between the perceived environmental benefits of SHC and continuance usage intention for millennial consumers. The hypotheses were statistically tested using online survey data, and the respondents were Korean female millennials aged between 25 and 39 years who had online shopping experiences of SHC within 3 months. Furthermore, 263 responses were analyzed by confirmatory factor, hierarchical regression, and conditional process analyses using SPSS, AMOS, and PROCESS v3.3. Results validated that the perceived environmental benefits of SHC and fashion leadership have positive effects on continuance usage intention of purchased second-hand items. Fashion leadership also moderates the relationship between the environmental benefits of SHC and continuance usage intention, showing that as the level of fashion leadership increases, the environmental benefits have more positive effects on continuance usage intention. Theoretical and practical implications were also discussed. This study will help bridge theoretical and practical gaps between purchasing and using SHC by focusing on the interaction effect of fashion leadership and its perceived environmental benefits.
