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: This descriptive study was done to evaluate the attitude and practice of hand-washing by student nurses. Method: The subjects of the study were 463 senior and junior undergraduate student nurses and RN-BSN students. The questionnaire was developed by the researchers Data were collected from Oct. 16 to Dec. 20. 2001. and analysed by SPSS/WIN. General characteristics. attitude and practice were analyzed by frequency and percentage and differences in attitude and practice according to grade and practice setting were analyzed with $x^2$ test, t-test or ANOVA. Result: 1) The mean frequency of hand-washing was 6.63. Senior students washed more frequently than junior students. 2) The reasons for non-compliance were 'not being accustomed', 'forgetting', and 'not accessible'. 3) The mean time for hand-washing was 23.79 sec., less than the stated appropriate time of 42 18 sec. 4) 90% of the students washed their hands 'after contacting excretions and contaminated items' and few washed 'before giving care to the client'. 5) Most students washed hands rotationally rubbing with soap and water. 6) While washing, they removed their rings more often than their watches. 7) Soap bar (52.8%) and paper towel (69.6%) were most frequently used as decontaminating agent and drying method, but detergent solution (74.2%) and paper towels (60%) were considered as the most appropriate agent and method. 8) Hand-washing was perceived important generally 'to protect from cross-infection'. 'to protect one-self' and 'the most cost effective'. 9) All students responded nurses should practice 'hand-washing.'

The principal objective of this study was to evaluate elementary students' awareness of the importance of hand washing, as well as their hand-washing behavior. The data was collected by self-reported questionnaire from 697 students in elementary schools with serving food in a classroom in Busan. Their hand-washing frequency was high, at '3~4 times per day (37.0%)'. 51.0% of the respondents did not wash their hands that often because they were 'not accustomed' to washing their hands, and 35.9% of respondents regarded washing their hands as 'annoying'. The most frequently reported hand washing agent was 'soap and water (71.4%)'. Approximately 95~98% of the respondents always washed their hands after using the bathroom, 87.9% of them washed their hands before eating food, and 86.7% of them washed their hands upon returning home. However, 27.3%, 34.1% and 65.9% of the respondents did not wash their hands after handling money, after eating, and after coughing or sneezing, respectively. Significant factors related to increased hand-washing frequency were gender (p<0.001) and the period of attendance at kindergarten (p<0.05). The mean scores of importance and performance of hand washing were significantly higher for girls than for boys. The group with higher rate (over 4.5/5.0) for the importance of sanitary hand-washing behavior showed significantly higher scores in hand-washing behavior before serving food and before eating than those of the lower rated group (below 4.0/5.0). This study shows that sanitation education is required not only for food handlers but also for students in school foodservices.

본 연구는 대학 구내 휴게음식점 종사자의 손 씻기 의식과 실천, 그리고 그들의 손의 오염지표미생물 오염도를 알아보고자 수행되었다. 이를 위하여 일개 대학 구내 휴게음식점의 조리종사자를 대상으로 설문조사, 관찰조사, 그리고 미생물 시험을 행하였다. 설문조사는 개별 직접면접을 통해 이루어졌으며, 관찰조사는 화장실에서 대상자가 알아차리지 못하도록 수행되었다. 손의 미생물 오염도 실험은 식품공전에 따라 수행하였다. 설문조사 응답에 비해서 관찰조사에서는 손 씻기와 손 위생관리가 매우 미흡하였다. 설문조사와 관찰조사 사이에 화장실 사용 후 손 씻기 실천/이행 여부, 시간, 사용 제제, 씻는 부위, 손 말리는 방법, 물의 온도, 그리고 물 잠그는 방법에서 유의한 차이가 있었다(p<0.05). 대상자의 손에서 작업 전에 비하여 물로 손을 씻은 후에는 일반세균, 총대장균군, 분변성대장균 및 대장균 오염도가 낮게 나타났으며, 향균비누로 손을 씻은 후에는 포도상구균을 포함하여 모두 불검출이었다. 설문조사와 관찰조사를 통해 대상 종사자의 손 씻기 의식과 실천에는 차이가 있다는 것을 알 수 있었으며, 일부 종사자의 손에서 대장균군, 분변성대장균군, 대장균 및 황색포도상구균이 검출되어 손 씻기 실천/이행 및 손 위생관리가 불량함이 확인되었다. 본 연구는 이들 휴게음식점 종사자의 양호하지 못한 손 위생관리와 ��거절한 손 씻기가 개선되어야 하고 개인위생과 식품안전을 위한 교육 및 훈련이 더 필요하다는 것을 시사한다.

In order to investigate the detergency of the mixture of compact detergent and bleaching agent to fabric stained with a coffee and a red wine, respectively, and a japanese wet stained fabrics, to evaluation of detergency was studied under various washing conditions. In order to study the effect of alkaline agent addition on the detergency, the soda ash was added in the compact detergent system. The results are as follows : In a low temperature washing condition, the alkalinity of washing liquor effected more the removal of the composite stained fabrics than that of oilic stained fabrics. For the colored stained fabric such as red wine stained sample, the influence of the repeated washing treatment on the detergency was not significant factor. On the other hand, the influence of the repeated washing treatment for the coffee stained and japanese wet stained fabric on the detergency was gradually increased.

The effects of silane coupling agent on the performance properties of cotton fabrics treated with loess and its washing durability were investigated. Mean average diameter of loess was 17.88㎛ and main components were SiO₂, Al₂O₃ and Fe₂O₃. By using the cationic agent, the dyeability of cotton fabrics was improved. The washing durability, antibacterial property and deodorization rate were improved and very good emissivities of far infra-red rays were obtained by using the silane coupling agent. And also the mechanical properties of cotton fabrics, such as primary hand values, were improved.

Pure tantalum powder has been produced by combining Na as a reducing agent, $K_2$TaF$_{7}$ as feed material, KCl and KF as a diluent in a stainless steel (SUS) bomb, using the method of metallothermic reduction. And we examined various types of after-treatment that affect the high purification of powder. A significant amount of impurities contained in recovered powder was removed in various conditions of acid washing. In particular, 20% (HCl + HNO$_3$) was effective in removing heavy metal impurities such as Fe, Cr and Ni, 8% H$_2$SO$_4$ + 8% $Al_2$(SO$_4$)$_3$ in removing fluorides such as K and F from non-reactive feed material, and 2% $H_2O$$_2$ + 1 % HF in removing oxides that formed during reaction. Significant amounts of oxygen and part of light metal impurities could be removed through deoxidation and heat treatment process. On the other hand, because it is difficult to remove completely heavy metal impurities such as Fe, Cr, and Ni through acid washing or heat treatment process if their contents are too high, it is considered desirable to inhibit these impurities from being mixed during the reduction process as much as possible.

렌즈 세척제인 ReNu$^{TM}$의 안자극테스트를 한국식품의약품안전청의 고시에 따라서 Draize방법(1959)을 사용하여 분석하였다. 부가해서 검사 항목의 잠재성 독성테스트를 위해서 염증세포와 비염증세포의 비율에서 역시 눈 분비물에 대한 세포도말표본사용으로 관찰하였다. 검사에서 각막, 홍채, 망막, 그리고 공막에 대한 조직학적 변화들은 역시 모든 실험동물에서 관찰되었다. 각막과 결막의 약간 자극성은 벼비척그룹에서 점안후 1, 2, 3일에서 관찰되었다. 이러한 지점에서의 안점막자극지수(MIOI)는 각각 4.17, 3.00, 1.33으로 확인되었다. 세척군에서 각막과 결막의 약간의 자극은 각각 0.67과 1.33으로서 MIOI로서 점안후 1일과 2일에서 관찰되었다. 따라서 ReNu$^{TM}$은 비자극성 물질로 생각된다. 왜냐하면 MIOI는 세척군과 비세척군 모두에서 전체 실험기간을 통해서 5.00이하로 관찰되었다. 급성안자극계수(IAOI)는 역시 4.17로서 확인되었다(점안후 일일). 일부의 예외들은 비세척군의 점안후 1일에서 분비물에서 염증세포 비율의 경향이 증가되었다. 그러나 유의성은 없었다. 한편 안분비물의 도말세포관찰에서 의미있는 변화들은 본 연구에서 관찰되었다. 부가해서 각막, 홍채, 공막 위에서 비정상조직 변화는 역시 비처리된 대군군 눈과 비교해서 ReNu$^{TM}$, 점안군에서는 탐지되지 않았다.
