This study intends to identify applicability of natural dye extracted from Aplysia kurodai, aiming to standardization of Aplysia kurodai natural dyeing through scientific validation by analyzing characteristics of pigment elements to review dyeability, colorfastness and antibacterial activity. Such material as silk fabrics that is animal fiber were used for this purpose, and derived following summarized results. UV/VIS spectrum analysis on the pigment of Aplysia kurodai that was extracted from purple gland showed that maximum absorbtion was near 540 nm. The silk fabric optimal dyeing can be achieved at a temperature of $55^{\circ}C$ with a colorant concentration of 5%. Dyed at $55^{\circ}C$ with interval of 10~90 minutes for identifying dye uptake over time to observed slow increase of dye uptake over time, and equilibrium occurred at 50 minutes. For dye uptake according to pH, while dye uptake was superior in acidity, it decreased rapidly in a base after pH 7. For color changes according to pH variation, it was reddish purple in acidity and was purplish red in a base. For color changes according to mordanting method, more clear color change had been obtained when process with aluminium pre-mordanting than non-mordanting and post-mordanting. The colorfastness to light, perspiration and washing was 1, 4~5, and 3~4 ratings respectively. The silk fabric dyed with Aplysia kurodai demonstrated excellent antimicrobial activity to Staphylococcus aureus and Klebsiella pneumoniae. The Aplysia kurodai can be used as a new colorant for the natural dyeing of silk.

The purpose of this study is basic data for developing baseball uniform in the future by carrying out a survey of amateur baseball players on the wearing pattern of uniform and inconvenient details. To do this study, a survey targeting 307 male social baseball players in their 20s to 40s was conducted, and a preliminary survey through interview with designers, MDs and patternmakers had also been carried out and analyzed prior to the main one. The result shows that armpit and back patches get wet with perspiration the most, and patches around knees are likely to be worn out because of frequent sliding. Thus, they are dissatisfied with poor protective function the most and need quilted pads around knees. Answers for a question on injuries during games indicates that shoulder injuries due to pitching or batting and abrasion owing to sliding are most common and knee injuries are also frequent. As for the wearing satisfaction of uniform, they want elasticity and breathability of textile to be improved; they are not satisfied with its design and fit because they think top and bottoms are much too long and uncomfortable; they often find dirt inside of the uniform during games. Besides, they find it very difficult to remove dirt from the uniform even after washing. There has been a growing population of amateur baseball players over recent years, so this study would help develop functionally improved uniform and be used for developing uniform for professional baseball players.

The purpose of this study was to identify the effect of hand acupuncture for reduction of dysmenorrhea. 71 female middle school and high school students were selected as subjects from April to May 2001, among which 38 students consisted of the experimental group while 22 students were the control group by convenient assignment. The experimental group participated in hand acupuncture treatment. The experimental treatment was to puncture corresponding points(A4, A5, J1, J3, J23, H2, F7) on both the palm and back of a hand with disposable acupuncture needles and to remove needles after 20-30 minutes' recess during which the subjects reposed themselves on bed. The collected data were processed using the SPSS PC Program and analyzed using $X^2test$ and The results of this study were as follows 1. The symptoms of premenstrual syndrome have decreased, but no significant differences were statistically observed between hand-acupunctured group and non-hand acupunctured group. 2. Subjective pain degree has decreased after hand acupuncture. 3. As for objective pain degree, a significant reduction in voice change was observed between two groups. Facial expressional changes and perspiration degree reduced but showed no significant statistically changes between two groups. 4. Comfort has increased after hand acupuncture. These results suggest that the hand acupuncture therapy works effectively on easing menstrual pain and symptoms as well as partially on reducing discomfort. It is particularly efficacious for a reduction in subjective pain and facial expressional changes in positive respect. Therefore the hand acupuncture therapy can be considered as an independent nursing intervention for dysmenorrhea reduction.

This study conducted a questionnaire survey of family restaurant employees in Seoul on their satisfaction and preference in working uniforms, and analysed the result to suggest adequate designs to serve the purposes of uniforms. The result is as follows - First, many pointed out a need to improve generally showing a low satisfaction with varying degrees according to sexes and ages. More women complained about colors, designs, materials and sizes than men did, and young employees in their twenties wanted better designs, colors and sizes in the order while those in their thirties and forties were dissatisfied mostly with materials. The need fur the improvement was focused on function and designs, and as for uniform materials, perspiration absorbency had the highest level of dissatisfaction. Second, about 40% of the respondents said the skirt width, pants length, and sleeve width were trio small or too big, therefore it is vital to improve uniform sizes. Third, the employees on duty felt uncomfortable mostly when they sat, and the neck and armhole parts were the most uncomfortable. The most easily tainted parts were in the order of the collar, front hem, and sleeve seam for upper garments, and the hip, bottom hem, and pleats for lower ones. Therefore it is required to develop functional uniforms considering the body features and momentum. Fourth, the most preferred material was that guaranteed easy movement and good air-permeability, and colors were in the order of white, beige and black for upper garments, and black, beige and blue for lower ones. And plain, natural and stripped patterns were preferred by both men and women. As seen so far, restaurant employees were mostly dissatisfied with the design, movement, and function of their uniforms demanding functional ones made of better and comfortable material. Uniform designs were suggested based on the analysis of the demonstrative rese.

The aim of this study was to elucidate dyeability and antimicrobial activity of cotton fabrics dyed with Sophora Radix extracts according to various mordants. Dyes were extracted from Sophora Radix using ethanol. Then, cotton fabrics were dyed with extracts two times by post-mordanting method in which the extract was 60% (owf, the mordant was 3% (owf), L.R was 1:20, the temperature was 60~7$0^{\circ}C$, the time of dyeing was 60min., and the time of mordanting was 60min.. The dyeability was evaluated by surface color and color fastness. The skin microorganism was evaluated on S. sureus, B. subtilis, S. epidermidis, P. acnes, P. aeruginosa, E. coli, A. niger, C. albicans and T. mentagrophytes. The results are as follows; 1. When mordants were treated, surface color was 3.3Y to 0.1 GY in H (hue) value which indicated greenish yellow to yellow 2. The color fastness to perspiration, dry-cleaning, rubbing, and washing stain fabric showed 4~5 degree. The color fastness to light was improved to 4 degree by treatment of mordants. The color fastness to washing was 2 degree which was somewhat poor. 3. Cotton dyed with ethanol extracts was excellent on S. aureus, B. subtilis, S. epidermidis and p. antis. But that showed poor antibacterial activities on P. aeruginosa and E. coli such as gram negative baterials 4. Antibacterial activity of cotton fabrics dyed didn't be improved by treatment of mordant 5. Antifungal activity of cotton dyed with ethanol extracts was excellent on T. mentagrophytes. Especially, on T. mentagrophytes there was no growth of fungus during 72 hours in cotton dyed mordanting with SnCl$_2$.$_2$$H_2O$.

Objectives : To examine various ways non-glutinous rice has been applied in different formulas of "Shanghanlun" and the relationship between non-glutinous rice and the formulas' effects. Methods : First, texts that included non-glutinous rice were selected from the "Shanghanlun". Then, they were categorized according to the application of non-glutinous rice, followed by analysis of its relationship with each formula. Results : Most formulas that used non-glutinous rice in raw form when decocting with other ingredients included Shigao. Non-glutinous rice alleviates coldness of Shigao as in the case with Taohuatang where it stops diarrhea. Non-glutinous rice used in Wumeiwan warms the center and boosts Qi and helps the medicinal ingredients to bind when made into pellets. In Guizhitang and Lizhongwan, non-glutinous rice assists Stomach Qi. In Shizaotang, porridge is taken after diarrhea to help quick recovery. To prevent damage of Zheng Qi, Baisan can be mixed with rice water for administration. The level of cathartic effect can be managed through giving cold or hot porridge to the patient according to his/her response to the medicine. Mazirenwan, Mulizexiesan, Banxiasan, Sinisan, Wulingsan are mixed in rice water for administration. It makes it easier to swallow than when mixed with plain water. The application of rice flour is either internal or external. In Zhufutang, where rice flour is parched, it harmonizes the center and stops diarrhea. In Daqinglongtang when there is too much perspiration, warm powder is sprinkled on the skin to stop sweating. Clear porridge in Jiuziyisifang and rice flour in Shechuangzisan were exclusive to "Jinguiyaolue", while Baisan and rice water mixture could only be found in "Shanghanlun". Conclusions : The excavation and research on various ways non-glutinous rice was applied in treatment holds certain meaning in contemporary practice of Korean Medicine where treatment leans heavily on medicinal treatment rather than food, and all ingredients are boiled together in large quantities for most decoctions.

This study establishes basic data for the development of a new Chemical, Biological, and Radioactive (CBR) protective clothing by selecting the ventilation position to optimize thermal comfort on the basis of the opening and closing of each part. Participants were eight men in their 20s who had previously worn CBR protective clothing. After vigorous exercise and perspiration, the microclimate of the clothing and skin temperature was measured. Results revealed that when the ventilation zipper was opened after exercising, the skin and clothing microclimate temperatures, which had increased during the exercise, decreased in the chest and shoulder blade regions. The clothing microclimate humidity decreased in the chest area. The change was greatest in the chest region; the skin temperature decreased by 0.2℃, the clothing microclimate temperature by 2.7℃, and the clothing microclimate humidity by 3.2%RH through ventilation. Thus, the opening that allows the exchange of accumulated heat and moisture while wearing the CBR protective clothing is efficient.
