The purpose of this study is to identify the handwashing knowledge and attitudes of resistered nurses on general wards. Subjects for this study include 182 nurses working in general wards of a hospital in Seoul area. Data were collected by a questionnaire from July 30 to August 10,1996. Statistical analyses were done by the SPSS/PC program. The techniques used in this sudy included frequencies, chi-square test. The results of this study are summarized as follows. 1. 34.6% of the respondents reported that they washed their hand an average of 5 to 7 times during the work day. 2. 38.5% of the respondents reported always washing after each patient contact. Only 9.9% always washed before contact with a patient. 3. 56.6% of the respondents reported a washing time of 10 to 20 seconds, whereas 29.1% washed 21 to 30 seconds. Chi-square tests were employed to determine any differences in handwashing frequency and duration by age, working years, work position. There were no satistically significant differences among the variables. 4. 95.6% of the subjects used water and plain soap during the washing process. The respondents washed the palms of the hands, the backs of their hands and between their fingers(33%). Only 17.6% removed rings before handwashing. Similarly, 11% removed their wristwatch. The majority(96.2%) reported that they used communal textile towel to dry their hands. When asked what method they used to turn off the water faucet after washing, 98.4% reported using direct hand-to-faucet contact. 5. Nursing activities that showed the highest handwashing rates was after wound dressing(22.9%), followed by suctioning(21.4%), injection(21.2%), inserting catheter(18%). 6. Reasons cited for reduced handwashing frequency included being too busy to wash more often(74.7%), no need to wash more often(11.0%) and dry skin caused by frequent handwashing(3.3%). 7. When asked where they obtained their current knowledge of handwashing techniques, they reported professors(73.6%), resisted nurses(14.8%) and supervisor(6.6%). 8. Nursing staff thought that proper handwashing was important factor in decreasing nosocomical infections(72.4%).

The purpose of this research is to provide accurate information of household washers and detergents for consumers, so that help the producers who make washing machine and detergent to get basic material and also help consumers to choose washing machine. Experiment was proceed with two type of washers to compare energy consumption, washing performance, rinsing effectiveness further, damage caused by entanglement of laundry and fabric was assessed. Detergent P and T were used to compare the performance related to differences of ingredients of detergent. Soiled fabrics of EMPA 108 set were used to evaluate performance of washing by different types of contamination. A summary of experimental results are : First, for the consumption of water, drum-type washer consumed 53% less than pulsator-type washer. On the other hand, the washing time was almost similar for both these machines, but pulsator-type washer showed shorter progress, implying that power saving was more efficient in this case. Second, the drum-type washer showed better performance for contamination with all types of detergent, but the pulsator-type washer showed better rinsing performance. Third, the drum-type washer performed less data of tangle level and fabric damage. Fourth, detergent "P" exhibited better washing performance than did detergent "T", regardless of the type of soil. And with no limit of detergent variety, water-soluble protein soil showed high removal rate, liposoluble soil especially pigment was hardly removed.

Background: The purpose of this study was to identify the connection between handwashing and toothbrushing, focusing on eating habits, and to verify whether eating habits can be used as an action cue for forming health habits. Methods: This was a cross-sectional study using secondary data from the 2019 community health survey. The participants included 229,099 adults aged 19 years or older, representative of the South Korean people. We employed two dependent variables: one was washing hands, and the other was brushing teeth. Eating habits was a major independent variable. Socioeconomic variables, such as age, gender, income, occupation, economic activity, education, and residence were adjusted as confounders. Multivariate logistic regression was performed to calculate adjusted odds ratio and 95% confidence intervals. Results: Most of the participants had good health behaviors: those who wash their hands and brush their teeth were each approximately 80%. Our finding indicated that brushing teeth and washing hands can be connected with eating habits. After adjusting for confounders, it was found that people who wash their hands before meals (compared to those who did not wash their hands before meals) had a higher toothbrushing rate after meals (i.e., socioeconomic status) (Adjusted Odds Ratio: 2.0, Confidence Intervals: 1.9 to 2.1). Conclusion: Those who practice either washing hands before meals or brushing teeth after meals were found to have a connection between washing hands and brushing teeth based on the results of practicing other health behaviors. This implies that eating habits can be connected as a behavior cue to promote health habits, such as washing hands before meals and brushing teeth after meals.

The purpose of the study was to provide the basic for the prevention of infection control by analyzing the level of recognition and practice of dental hygiene students. It is important for dental clinic staffs to know and practice infection control measures in favor of effective infection control. Thus, this study conducted an one-month questionnaire survey (during October 2008) for dental hygiene students who ever experienced in 16-week clinical practice, and analyzed total 206 questionnaire forms as collected from them, so that it could determine potential associations between their recognition and practice of infection control and thereby suggest an efficient solution for infection control in dental hygiene. 1. It was found that our students' recognition about infection control averaged $4.49{\pm}.58$ points on the whole, and they were best aware of instrumental disinfection and sterilization among other measures, which was followed by hand washing, extirpation control, post-sterilization management, personal protective outfit and instrumental surface maintenance respectively. 2. It was found that our students' practice of infection control averaged $3.85{\pm}.57$ points on the whole, and they practiced hand washing most actively among other measures, which was followed by extirpation control, post-sterilization management, instrumental disinfection and sterilization, personal protective outfit and instrumental surface maintenance respectively. 3. It was found that our students scored higher mean points in recognition about every measure of infection control than those in practice (t=15.676, p=0.000). Particularly, it was notable that there were significant differences between their mean points in recognition and practice of some infection control measures, such as instrumental surface maintenance (t=15.361, p=0.000), personal protective outfit (t=15.245, p=0.000) and instrumental disinfection and sterilization (t=11.169, p=0.000). But there was least significant difference between mean points in recognition and practice of hand washing (t=5.460, p=0.000). 4. For potential associations between recognition and practice of infection control, it was found that higher recognition was in significantly positive associations with higher practice in every measure of infection control (r=.478, p=.000), such as extirpation control (r=.630, p=.000), instrumental disinfection and sterilization (r=.477, p=.000) and post-sterilization management (r=.433, p=.000). 5. It was found that there were differences in our students' recognition depending upon availability of infection control guideline (t=4.587, p=.011), and there were significant differences in practice depending on necessity of infection control education on a statistical basis (t=2.229, p=.027). Overall, it is found that our dental hygiene students are very likely to practice hand washing and extirpation control, because both of these measures are relatively easy to practice or are considered legally binding.

A small washer powered directly and solely by thermal radiation was constructed and tested to explore the feasibility of using solar energy or other types of thermal radiation for washing and cleaning. In principle, TA (ThermoAcoustic) washers have the benefits of simpler design and operation and fewer energy conversion processes, thus should be more energy efficient and cost less than electric washing/cleaning systems. The prototype TA converter we constructed could sustain itself with consistent fluid oscillations for more than 20 minutes when powered by either concentrated solar radiation or an IR (infrared) heater. The frequencies of water oscillations in the wash chamber ranged from 2.6 to 3.6 Hz. The overall conversion efficiency was lower than the typical efficiencies of TA engines. Change in water temperature had little effect on the oscillatory flow in the TA washer due to its low efficiency. On the other hand higher water temperatures enhanced grease removal considerably in our tests. Methods for measuring the overall conversion efficiency, frictional loss, and grease removal of the TA washing system we designed were developed and discussed.

이 연구의 목적은 초, 중, 고등학교 학생의 손씻기 실천과 감기, 설사, 눈병, 식중독 등의 감염성 질환 이환과의 관련성을 파악함으로써 손씻기의 중요성을 강조하고, 학교 청소년의 손씻기 실천율을 향상시키기 위한 기초자료를 제공하고자 하였다. 전국 16개 시도에 거주 중인 초등학교 4학년부터 고등학교 3학년까지 학생을 대상으로, 가구방문을 통한 방문면접과 온라인 조사를 9월 5일부터 9월 25일까지 시행하였다. 조사응답자의 일반적 특성과 손씻기 실태 및 손 씻는 방법을 독립변수로, 감기, 설사, 눈병, 식중독 등의 질병감염 여부를 종속변수로 하여 카이제곱검정과 이분형 로지스틱 회귀분석을 실시하였다. 연구 결과를 종합해보면 식중독을 제외한 감기, 설사, 눈병 등의 질병감염 경험이 학년이 높을수록 많았다. 특히, 감기 감염경험의 경우 남성보다 여성에서, 비누와 물을 사용한 손씻기보다 물 또는 손소독제만 사용한 군에서, 손등을 씻는 군보다 손등을 안 씻는 군에서 감기 경험률이 높았다. 손씻기 실태조사 및 청소년건강행태온라인조사에서 학년이 높을수록 손씻기 실천이 낮은 점을 고려할 때, 이 연구에서 학년이 높을수록 질병감염 경험률이 높고, 특히 감기감염경험의 경우 손씻기 방법이 좋은 군일수록 경험률이 낮은 것은 기존연구와 마찬가지로 손씻기가 감기와 같은 감염병의 예방에 영향을 미치는 요인으로 판단된다. 청소년은 집단생활로 인한 감염병 질환의 위험이 높은 점을 고려할 때, 학교 내에서 청소년의 비누를 사용한 올바른 손씻기를 교육하고, 실천율을 향상시킬 수 있는 방법에 대한 연구와 정책마련이 필요하다.

This study investigated the effect of aftertreatments such as using the softener or starch on the mechanical properties of knitted fabrics. The mechanical properties of fabrics, hand value(HV) and total hand value(THV) were measured and calculated by the KES-F system. The main results are as follows: The values of tensile energy(WT), coefficient of friction(MIU) and geometrical roughness(SMD) were increased by softener but decreased by starch treatment. However, the values of tensile linearity(LT), bending(B, 2HB), thickness(T) and weight(W) were increased by starch but decreased by softener treatment. Tensile resilience(RT) was increased not only by softener but also by starch treatment. It showed that the levels of FUKURAMI, NUMERI and SOFUTOSA were increased by the treatment of softener and the levels of KOSHI and SHARI were increased by the treatment of starch. Total hand value(THV) was lower in fabric with starch treatment than fabric with none treatment.

청소년의 건강증진을 위한 보건교육 프로그램 중 손씻기에 대한 교육을 기획하는데 있어 기초자료를 제공하고자 2011년, 2012년, 2013년의 청소년건강행태온라인조사 원시자료를 이용하여, 중학생 및 고등학생의 손 씻기 실천 행태를 분석하였다. 자료 분석은 조사에 참여한 표본이 우리나라 청소년의 대표성을 갖도록 지정된 가중치를 적용하였으며, 자료는 SPSS 18.0 프로그램을 이용하여 빈도 분석 및 교차분석을 실시하였다. 우리나라 청소년의 손 씻기 실천 행태는 학교에서 식사하기 전 '전혀 씻지 않았다'로 응답한 학생수가 2011년도에 22,257명(29.4%), 2012년도 22,375명(30.5%), 2013년도 13.153(18.5%)명으로 다른 항목과 달리 계속적으로 주의깊게 관찰해야 하는 상태로 유지되었다. '학교에서 식사하기 전 전혀 씻지 않았다'는 항목에 대해 최근 3개년간의 추이를 확인한 결과 도시구분에서는 대도시와 중소도시가 군단위의 소도시 보다 유의하게 전혀 손을 씻지 않는 경향을 보였고, 학교유형에서는 여학교가 남녀 공학이나 남학교 보다 학교에서 식사 전 전혀 손을 씻지 않았다고 응답한 비율이 지난 3개년 간 계속해서 높은 경향을 보였다. 또한 학교구분에서는 중학교와 일반 고등학교가 특성화 고교보다, 성별에서는 여학생이 남학생보다, 학년 구분에서는 고학년으로 학년이 올라갈수록 '학교에서 식사 전 전혀 손을 씻지 않았다'고 응답한 학생이 유의하게 많은 것으로 나타났다. 이로써 손 씻기에 대한 학교 보건 교육 시 '식사 전 손 씻기'에 대한 교육을 특히 강조해야 하고, 학교에서 식사 전 '전혀 손을 씻지 않았다'고 응답한 비율이 높았던 인구학적 특성의 대상에 대해 보다 세심한 교육과 계속적인 관찰이 요구된다.
