This study focuses on the effects of dyeing conditions and mordanting conditions, changes of colorfastness, antibacterial properties and UV protective of silk fabric dyed with Laminaria japonica extracts. A natural colorant was extracted from Laminaria japonica using distilled water as extractants. According to the results, maximum dye uptake (K/S) were obtained at 100% V/V colorant concentration, $80^{\circ}C$, 60 min and pH 2. Silk fabric was dyed with Laminaria japonica extract at $80^{\circ}C$ for 60 min with pre-treatment or post-treatment of various metal salts as mordants. The Laminaria japonica extracts produced yellow hue on silk fabric in pre-mordanting and manifested green yellow hue mordanted with $CuSO_4$ in post-mordanting method. Mordant $CuSO_4$ for silk fabric was found to give good light fastness (rating 4). UV protection property did not increase significantly upon mordanting.

Objectives : Joongjeo($TE_3$) Supplementation Aekmoon($TE_2$) Draining is a method belongs to Ohaeng-acupuncture, using directional supplementation and draining. Methods : This study was designed to investigate the effects of $TE_3$ supplementation $TE_2$ draining on changes in cerebral blood flow(rCBF) and mean arterial blood pressure(MABP) in normal rats. For these reasons, the present author investigated rCBF and MABP using laser doppler flowmeter in normal rats. In addtion, the present author also investigated action mechanisms of $TE_3$ supplementation $TE_3$ draining on changes in rCBF and MABP too. Results : In this results, $TE_3$ supplementation $TE_2$ draining elevated rCBF in time-dependent manner, but MABP levels decresed by $TE_3$ supplementation $TE_2$ draining. Pre-treatment with indomethacin (IDM), an inhibitor of cyclooxygenase, inhibited increase of rCBF effectively. But pre-treatment with methylene blue(MTB), an inhibitor of guanylate cyclase, decreased rCBF levels. In addition, pre-treatment with IDM also decreased MABP levels, but pre-treatement with MTB increased MABP levels. Conclusions : In conclusion, these results suggest that $TE_3$ supplementation $TE_2$ draining is effective to treat patient with disease related to cerebral ischemia, because $TE_3$ supplementation $TE_2$ draining can increase rCBF. In addition, the mechanisms are thought to be related to guanylate cyclase pathways.

In recent years, the application of digital textile printing has increased. The benefits of using this method include the ease of sampling and the production of printed textiles. However, the production process of digital textile printing differs from that of conventional printing. For successful digital textile printing by ink-jet technology, the pretreatment of fabrics is very important in order to overcome the following problems. Low viscosity ink can spread easily on the textile surface leading to poor resolution. As a result, the combination of ink and pretreatment chemicals is still impractical and consequently most fabrics used in digital textile printing will require a pre treated coating in order to prevent the ink colours from bleeding on the fabric. Research presented in this paper shows some preliminary attempts to establish the relationship between the pre treatment and the digital textile printing quality. Various cotton fabrics were treated with pre treatment agents including ingredients like thickener, alkali and humectant, and then ink spread effect and colour yield of printed fabrics by reactive ink were analysed by using an optical microscope and K/S value. The results show that digital textile printing quality on cotton fabrics can be optimized with appropriate pre treatments.

I assessed the B($a$)P content from the Ginseng extract, Red ginseng extract, and Ssangwha extract which have high viscosities. It wasn't easy to extract oil from these samples, consequently measuring of B($a$)P was difficult. In order to know the exact detecting contents, I injected standard material of B($a$)P to the above extractions and pre-treated for measurement but it was also difficult to measure of contents exactly. To improve of detecting method, I removed mucinous materials using a 85% phosphoric acid solution or 10% citric acid solution and then processed continuously with $60^{\circ}C$ hot water. The analysis revealed that extracting the samples contained B($a$)P determined the rate of each 70%, 55%, 67% could increase. As a result the detecting method of B($a$)P contents could be improved.

The purpose of this study was to test whether Yoga exercise, one of muscle relaxation, helps to relieve chronic low back paln. Sample were selected from nurses who were worked at K medical center in the period from March 18 to April 23, 1996. The sample size was fifteen. The research design was one-group pretest-posttest design. To test the major research question, this study had the following procedure. The pretest included measuring individuals' degree of pain and discomfort depending on the scope and types of an range of motion, and their pain by their activity of daily living(ADL). The treatment was conducted twice every other week. The reason why this study had twice observations was to control history effect and maturation which treat internal validity in the research design of this study. In this research design, a treatment was to expose Yoga exercise to samples. The exercise was taken in 30 minutes per day for four days in a week (Two consecutive days and twice every other day). The posttest included re-measuring the individuals' the degree of pain and discomfort, and their pain by their ADL. Several hypotheses concerning effect of Yoga exercise was analyzed by the paired t-test, comparing the difference scores between pre and post tests. The results of this study was as follows. The first hypothesis that the post-treatment group taking the Yoga exercise had the pain score lower than the pre-treatment group was supported(t=3.31, p=.005). The second hypothesis that the discomfort score of the post-treatment group had lower than does that of the pre-treatment group was supported(t=2.75, p=.016). The third hypothesis that the post-treatment group had the pain score by ADL lower than does the pre-treatment group was supported(t=5.52, p=.000). In summary, this study examined the effect of a yoga exercise, one of muscle relaxation, on those who were suffered from chronic low back pain. The effect measured by the degree of pain and discomfort with a visual analog scale was statistically significant. The degree of pain according to postures in ADL also showed statistical significance. These findings showed that a yoga exercise was effective to alleviation of chronic low back pain. A pretest-posttest control group design, however, needs to get more accurate results since the design satisfies Internal validity. Consequently, yoga as an exercise cure improves an interaction between muscles and articulations, and performance of ADL for those suffered from chronic low back pain. Furthermore, this positive impact may be an effective method as nursing intervention for their physical, mental, emotional, social, and psychological recovery.

Whole process of textile printing is made by computer and it remarkably improves environment problem. This digital textile printing is becoming next step environment friendly textile printing method. But, still now range of textile possible for digital textile printing is limited, and also color analysis according to fiber types is not completed. The ink printed on the fabrics through DTP printer can be absorbed and fixed into textile without any blots by pre-treatment using suitable media solution for fabrics types. The chemical formulation of media solution used in the pre-treatment process varies according to the types of textiles and inks for DTP products. First, I studied reference books or articles about color analysis of digital textile printing. Second, I recorded pre-process, printing, post-process and coloring of silk, wool, nylon at same condition. After that, I analyzed $L^*\;a^*\;b^*$, Total K/S, ${\Delta}E$ and studied color intensity and coloring. According to this study, I suggested particular textile special for coloring and manual for affective coloring control. It showed that the performance of the digital printing on the Silk, Wool and Nylon blend fabrics treated by the media solution developed in this study was better than the one treated by the previous media solution for each single inks.
