The purposes of this study were to measure skin temperature and blood flow on the contralateral upper extremity when heat is applied to one upper extremity, were to compare the effect of contrast bath. The subjects were 38 healthy adults with no history of peripheral vascular disease. The subjects of contrast bath were 18 persons and the subjects of warm bath were 20 persons. The subjects of one group were seated with their right arm in water($42^{\circ}C$) up to the mid-forearm. The subjects of the other group were seated with their right arm up to the mid-forearm in water which was changed from warm to cold using the contrast bath technique. The continually changing temperatures and blood flow were measured by an independent observer at intervals of 10, 15, 20, 25 and 30 minutes respectively after the start of the procedure. The results were as follows. The temperature of the warm bath group rose 4.28% over the pre-experimental temperatures and the temperature of the contrast bath group rose 3.41%. There was no statistically significant difference between the two groups. The blood flow of the warm bath group rose 8.31% over the pre-experimental blood flow and the blood flow of the contrast bath group rose 17.24%. There was a statistically significant between the two groups 20 minutes after the start of the procedure. Thus the contrast bath is a more effective method than the warm bath to increase blood flow.

Cryogenic rolling combined with warm rolling has been found to be more effective than only cryogenic rolling procedure in improving the strength of a 5052 Al alloy. In this study, cryo-rolled 5052 Al alloys were aged at $175^{\circ}C$. Warm rolling was conducted after dipping plates into silicon oil bath. A notable increase of tensile strength is achieved by the precipitation during warm rolling. The mechanical behavior of this alloy was investigated by hardness and tensile tests. The microstructure was investigated by transmission electron microscopy. It was found that the cryogenic rolling combined with warm rolling was very effective in improving tensile strength.

This paper presents reference designs for vapor-cooled HTS/Copper leads rated at 25 kA and 40 kA and that satisfy a protection criterion. Each HTS section is cooled by the effluent helium vapor boiling from a 4.2-K bath. Each HTS section is based on a design concept in which a short portion of its warm end (77.3 K) operates in the current-sharing mode; such operation results in a considerable saving for HTS materials required in the HTS section. Two designs of "fully superconducting" vapor-cooled HTS sections, one rated at 25 kA and the other at 40 kA are also presented as comparison bases for the new HTS sections. Each warm end of HTS sections is coupled to an optimal vapor-cooled copper lead rated at the same current as that for the HTS section. The extra coolant required at 77.3 K at the coupling station, an optimal length of the copper section will be shorter than that optimized for helium-vapor cooling between 4.2 K and room temperature.mperature.

This study examined the changes in body temperature through conductive heat applied to the body and clarified the influences of body fluid on the thermal effects. Body fluid was measured using the Segmental Bioelectrical Impedance Analysis method. The subjects consisted of 13 men and 14 women. TBW was 37.56 (4.35 L for men and 29.93 (3.12 L for women, with the former being significantly (p<0.01) higher. The amount of body fluid in the right and left legs was 6.46 (0.83 L and 6.39 (0.86 L for men and 4.78 (0.49 L and 4.78 (0.49 L for women, respectively, with men's values being significantly (p<0.01) higher than women's on both the right and left sides. The maximal change in the surface temperature was 33.93 (0.61(C at the start of a warm bath to 3407 (0.61(C after 14 min for men. In contrast, the maximal change was 33.38 (0.99(C at the start to 33.73 (0.86(C after 18 min for women. For the other sites, the maximal temperature in Depths 1 and 2 was attained earlier for men than for women. The decrease in body temperature after the end of warming was more remarkable for men. Men had fluid with a higher conductivity than women, indicating influences of body fluid on the changes in body temperature. There were few changes in body composition with a partial bath having a crossed effect, indicating that this is a safe therapeutic method for elderly people.

This study was performed to inquire into recognition of cold and heat application. The subjects in the study were 429 adults who were collected by disproportional quota sampling according to age, sex. The instrument was 36 questions that constitured closed questions and semiopened questions that encluded general characteristics, recognition of cold and heat applications. and what will you do when requested cold and heat applications on abdomial and perineal areas. Data were collected from september 25 to October 25, 1998. Data was analysed by SPSS/win, into frequency, Pearson correlation, t-test, ANOVA. The results were following. 1) The subjects consisted of male and female who was from teenage to fifty year old above. According to general characteristics, who endureed moderate cold-heat application, had constitutional fever, good sweat, and taked a cold bath accationally. And the woman think that their body were more cold than man. and the number of cold bath was less than man. Woman felt more harder than man that endured exposing cold. According to the recognitions of cold-heat applications, the 61.9% of the subjects think that cold application is more positive, and the 61.7% of the subjects think that heat application is more positive. 2) The subjects think that oral cavity, abdomen, back, extremes must be warm. 3) The percents of cold or heat application at abdomen were 77.4%, 86.5% respectely and the percents of cold or heat application at perineum were 56.9%. 93.6% respectely. With the above results. we know that the subjects have the fixed perceptions that each body part has to maintain its temperature. especially, they think that postpartum care is correlated with cold-heat application. So when we intervent nursing care, we also must regard their recognitions of cold and heat applications. and we need to educate and explain correctly about cold-heat application.

Purpose: To identify perimenstrual discomforts, coping and relief of symptoms in female workers. Methods: A convenience sample of 203 women who had worked were obtained from two hospitals in Busan. Data were collected through questionnaires from November 8 to 16, 2004. Three instruments were used in this study: the Perimenstrual Discomfort Questionnaire by Park(1988) and the Menstrual Coping Questionnaire and the Relief of Symptoms by Billings & Moos(1981) modified for this study. The data were analyzed by descriptive statistics, t-test, and ANOVA with SPSS 10.0 program. Results: The prevalence rate of dysmenorrhea was 81.3%. The total mean score for perimenstrual discomforts was 2.83 out of a possible total of 5 and the mean score for each category was, 3.08 for water retention, 2.95 for pain, 2.88 for negative affect, 2.83 for behavioral change, 2.73 for autonomic reactions, and 2.51 for concentration. According to these study results, statistical differences were found for age(F=2.76, p=0.04), feeling to menstruation(F=3.94, p=0.00), dysmenorrhea(t=4.26, p=0.00), and taking medication(t=2.09, p=0.00). The coping modes with the highest scores were 'take a hot bath'(99.0%)', 'rest and go to bed'(83.7%), 'regard menstruation as a physiological and temporary phenomenon'(76.8%), 'take a warm shower'(65.0%). The most frequently used methods to relieve symptoms were 'rest and go to bed'(70.0%), 'take a warm shower'(57.6%), 'take pain killers'(49.8%), 'apply hot water bag on painful parts of the body'(46.8%). Conclusion: Further research is needed to understand perimenstrual discomforts and the variables associated with them. Nursing intervention has to be considered in any program aiming to reduce perimenstrual discomforts.

본 연구에서는 전도열손실과 증발에 의한 열손실을 바탕으로 욕조의 자유표면에서 일어나는 온수의 열손실을 해석하고자 한다. 연구결과 욕조의 성능을 평가할 수 있는 식을 열전달 기본식으로 부터 관계식을 도출하였으며 이 식은 매우 시성적이며 정량적이었다. 특히 욕조 내 온수의 냉각은 증발에 의한 열손실이 지배적이었다. 또한, 온수의 온도 냉각 속도는 온수의 온도에는 크게 영향을 받지 않으나 욕실의 습도에 따라 크게 영향을 받는 것으로 확인되었다. 그러므로 욕조의 온도는 $41{\sim}45^{\circ}C$를 유지하며 욕실의 습도가 95％를 유지하는 것이 가장 효과적이라 판단된다.
