The purpose of this study was to evaluate thermal properties of lab gowns developed from the point of safety and work efficiency. We evaluated thermal and subjective responses of subjects wearing functional new lab gowns (Type B, C, D) and a popular lab gown on the market (Type A). Type B was a new lab gown made of woven fabric with functional cuffs. Type C was a new apron made of woven fabric with arm protectors. Type D was a new lab gown made of non-woven material with functional cuffs and openings around the armpits. Temperature in the climatic chamber was set at 19$^{\circ}$C as an indoor temperature in winter and at 24$^{\circ}$C in summer. There were no significant differences in rectal temperature and heart rate among four types of gowns and between two air temperatures for 120 min. Mean skin temperature was much higher in the type A and B than in He type C and D (p .05). In the 19$^{\circ}$C air, clothing microclimate temperature on the back was the highest in the type B and was the lowest in the type C (p .05). Clothing microclimate humidity was not significant differences among gowns. In subjective .esponses, subjects perceived that Type B was the warmest gown in the 19$^{\circ}$C and the hottest and more humid in the 24$^{\circ}$C than other gowns. Inversely, type C was the coolest gown among four gowns. Both in the 19$^{\circ}$C and in the 24$^{\circ}$C, the Type D had gained most responses of being comfortable. In conclusion, the temperature difference of 5$^{\circ}$C was more of an influencing factor than the difference from four types of lab gowns. Secondly, we recommend the manufacturers to make lab gowns with functional cuffs for safety purposes. Thirdly, the spread of the type of apron with arm protector will contribute to increase of the frequency of wearing in summer. Fourthly, it is necessary to study continuously about lab gowns with non-woven materials for researchers exposed to toxic chemical and biological materials.

The purpose of this study was to develop functional lab gowns in the view of safety and work efficiency. As the first step of this study, we surveyed on satisfaction rates, preferences and inconvenience items in regard of lab gowns. The data was obtained from 138 graduate students specialized in science and 113 medical students. Respondents answered that the first purpose of wearing lab gown was to protect body from danger. Wearing frequency followed with ‘always’, ‘as possible as’, and then ‘sometimes’. Forty-five percentage of respondents answered that they didn't wear lab gowns often in summer because of hot weather. The contaminated or damaged parts of lab gowns followed with cuffs, abdomen, thigh, lower part, and then chest. Washing frequency followed with ‘once a month’, ‘once per six months’, and then ‘more than once a week’ There were significant differences in normal wearing frequency, wearing frequency by season and washing frequency due to major. There were no significant difference by sex and major in all questions. In regard of the protective capacity of current lab gowns, most respondents answered that ‘It's normal’(60%), ‘It's enough’(21%), so that they didn't show much dissatisfaction. Forty-three percentage of respondents were not satisfied with cuffs. Respondents answered that the cuffs were in danger and inconvenient because of broad cuffs. In regard of color, preference for white were high and followed with ivory, light sky, light green. and then light pink. Materials of current lab gowns were cotton/polyester or polyester 100%. Sixty-eight percentage of respondents were satisfied with that and others were not. The reasons for dissatisfactions were as follows; those materials were not protective to chemicals thoroughly enough. Cotton/polyester materials were heavy. Wearing sensation of polyester 100% was not good.

본 연구의 목적은 중학생들의 과학자, 기술자, 공학과학자, 기술자, 공학자에 대한 중학생들의 이미지와 인식 비교 79자에 대한 이미지 및 인식을 비교 분석하는 것이다. 본 연구는 중학교 3학년 학생 110명을 대상으로 하였고, 검사 도구는 Fralick 등(2009)이 개발한 'Draw a scientist at work and draw an engineer at work'와 그에 대한 체크리스트를 번안 수정하여 사용하였다. 일하는 과학자, 기술자, 공학자의 그림을 그리고 외형적인 특징과 일하는 장소, 일하는 행동, 다루는 대상 또는 사물에 대하여 서술하도록 하여 분석한 결과는 다음과 같다. 첫째, 중학생이 인식하는 과학자가 취급하는 대상 또는 사물로는 플라스크, 비커, 시험관이 가장 많았으며 남학생과 여학생간의 차이가 없었다. 학생들이 그린 과학자 이미지에서 복잡한 기계나 설계도를 묘사한 경우가 다수 나타나 학생들이 과학자와 공학자를 유사하게 인식하는 반면 공구, 다리, 건물에 대한 묘사는 없는 것으로 보아 과학자와 기술자는 구분하여 인식하고 있었다. 둘째, 기술자가 일하는 곳은 공장이나 카센터 등으로 인식하였고 스패너, 망치 등의 공구를 이용하여 차량을 수리하는 것으로 묘사하였다. 기술자의 외형적 특징으로 과학자에서는 매우 낮은 비율로 나타났던 작업복과 모자의 빈도가 현저히 높게 나타났다. 학생들의 그림에서 나타난 기술자의 행동으로는 남학생과 여학생 모두 손으로 만들거나 고치는 공통적인 이미지로 표현하였다. 셋째, 공학자가 일하는 곳은 실내이며 기계를 다룬다는 공통적인 이미지를 가지고 있었으며 남학생의 경우 공학자가 컴퓨터로 설계하거나 발명하는 모습을 주로 표현한 반면 여학생들은 차량을 고치거나 만드는 일을 한다고 인식하여 성별에 따라 차이가 나타났다.

The purpose of this research is to suggest basic materials for the practical infection precaution program to protect health care workers from hospital infection by grasping their compliance level of Universal Precautions and examining the factors affecting them. The number of the health care workers we studied were 486, including the doctors, the nurses, and the lab technicians who were working in a university hospital. The period of this research was from Aug. 18th, 1997 to Aug. 30th, 1997. The method of the study was to measure the compliance level of Universal Precautions with the item of "Universal Precautions" established by CDC in 1987, and examine the questionnaire of 52 questions dividing related factors into socio-populational, individual, socio-psychological and organizational management ones. The data was analyzed by t-test. ANOVA, and chi-square test. The results were as follows : 1. An the compliance level of Universal Precautions, hand washing had the highest score(85.4%), and doctors(18.9%), nurses(44.0%), and lab technicians(7.6%), had a low compliance level in the safe handling of an injection syringe, and item not to handle patients and their samples when the subject suffered from dermatitis or injury had the lowest score of 17.1%. 23.3% of them said that they wear protection gown, goggles and mask. 2. Female's Compliance level of Universal Precautions Was higher than male. 3. The health care workers who had high recognition on Universal Precautions got significantly higher compliance level of Universal Precautions than those have low recognition on Universal Precautions(P<0.001). 4. The health care workers experienced a needle stick injury had a significantly higher compliance level of Universal Precautions than those who had not(P<0.000). 5. The health care workers who had infection protection education got a significantly higher compliance level of Universal Precautions than those who didn't(P<0.000). 6. The health care workers who had a firm belief in the effect of Universal Precautions got a higher compliance level of Universal Precautions than those who didn't. 7. The health care workers who had less conflicts between treating patient arid protecting them-selves got a higher compliance level of Universal Precautions than others with many conflicts. 8. The health care workers who had a high score in organizational management factors got a significantly higher compliance level of Universal Precautions than those with a low score(P<0.000). 9. Only 16.9 percent of the all respondents(82 in number) answered that they knew well or a little about the Universal Precautions, which is very low rate of recognition. 10. The variables which affected the score in organizational management factors were age, sex, education period, work experience, the kind of work, recognition on Universal Precautions, the experience of needle stick injury, revealing dangerous circumstance related to infection, and training on precaution again infection. According to the result above, compliance level of Universal Precautions showed high correlation with sex, the recognition on Universal Precautions, the experience of needle stick injury, training on precaution against infection, the belief in the effect of Universal Precautions, the recognition degree of conflicts and organizatinal management factors. These results could be used as the basic materials for the developing infection protection programs. Also, There should have a systematic training course to elevate a effective compliance level of Universal Precautions as well as the manageeent of infection protection programs.
