We are able to generate the stable plasma in open air and nitrogen using a corona plasma treatment system(CPTS) with a high voltage. This was applied to treat the surface of rather non-polar HDPE(High Density Polyethylene) intended for the improvement of adhesion of over-coated layers such as coatings, printing inks. The surface tension of HDPE was significantly improved by the CPTS. The characteristics of surface layer were evaluated by means of contact angle measurement, ATR-FT/IR spectroscopy, and it was found that functional groups were introduced into the surface layer of the HDPE. The use of nitrogen was increased the surface tension of the HDPE from 33.8 mJ/m^2 to 66.56 mJ/m^2, and highly effective method of HDPE surface modification could be realized.

The class of uterine malformation known as communicating uteri is characterized by two uterocervical cavities connected by an isthmic communication. We experienced case of communicating double uterus with double cervix, blind hemivagina and ipsilateral renal agenesis. The complaint of the patient was odorous vaginal discharge with lower abdominal pain unrelated with menstrual cycle. We confirmed these Mullerian anomalies by transvaginal ultrasound. IVP(intravenous pyelography), MRI(magnetic resonance imaging), hysterosalpingography and hysteroscopy. After vaginal septoplasty, her complaint was subsided. We report this case with brief review of literatures.

Uterine myomas are the most common pelvic tumor in women. These benign tumor generally arise in the uterinie wall and intraligamentary myomas are relatively rare cases. We experienced intraligamentary huge myoma. Preoperative GnRH(Gonadotropin Releasing Hormone) agonist therapy was done but the effect was nearly absent. Hystrectomy was done without complication. We report this case with brief review of literatures.

Addition of 0.5, 1.0 and 2.0g of succinic anhydride to 2g of sesame protein concentrates succinylated 44.9, 70.0 and 83.1% of the available amino groups, respectively. Considerable amount of phytate were removed in all sesame protein concentrates and the highest reduction was obtained by addition of 2.0g of succinic anhydride. Among the minerals investigated, high amount of calcium and magnesium were presented in defatted sesame flour. In the case of calcium, magnesium and iron, the contents were decreased as the degree of succinylation was increased. Most amino acid content of sesame protein concentrates was not changed by succinylation but lysine was slightly decreased. Result of color measurement showed that the higher degree of succinylation, the higher values of L and b were founded.

To investigate the effects of ethanol on the lipid metabolism in blood and liver, twenty one male Sprague Dawley rats had orally taken the 25% alcohol and 50% alcohol by 5g per Kg of weight during 3 weeks after the adjusting period. For the energy balance, 85% sucrose and 45% sucrose was added in control group and 25% alcohol group each. The weight was reduced by alcohol treatment according to the levels, otherwise the weight of liver and heart was little increased in alcohol groups rather than in control without significance. Moreover, RBC, WBC, hemoglobin and hematocrit were increased by alcohol treatment according to the levels without significance. Otherwise, adjusted bilirubin levels by 100g of weight was significantly increased by alcohol treatment dose dependently. Alcohol induced RBC degradation and increased circulated bilirubin because of liver damage. For blood lipid profiles, blood cholesterol was increased in 50% of alcohol group compared to that of 25% and control groups, otherwise, blood triglycerides (TG) was increased by 30% in 25% alcohol groups rather than in control but not significantly different. The hepatic lipid composition, cholesterol levels in alcohol treatment groups was lower than those in control. The hepatic TG was not influenced by alcohol treatment. The two reasons of decreasing hepatic lipids were suggested by 85% sucrose of control for energy balance more synthesized cholesterol and TG than those in 25 or 50% alcohol groups, and by cholesterol and TG could not be synthesized because of liver damage from alcohol.

Recently many studies which related to effective sampling method have been progressed and valuable data accumulated in foreign country. But, domestic technique is insufficient to evaluate the degree of disturbance so it is difficult to seek soli parameter. Thus the grasp of the degree of disturbance is effential to increase accuracy of reasonable parametern from laboratory tests. Also, the degree of disturbance of it was determined. Oedometer tests and Rowe cell consolidation rests reappeared in -situ state were conducted. And its result was compared and analyzed to deduces the degree of disturbance. From these tests, It can be inferred that the compression index generally is not affected and swelling index(C )and preconsolidation load (P )are increased because of the disturbance of soil. Also, it can be considered that consolidation curves given by two tests is little affected from desturbance. Conclusively, the results of two tests indicated that void ratio(e) and swilling index is independent of the degree of disturbance and it is reasonable to evaluate the degree of disturbance through it.

The DWTSG concept is proposed as a advanced steam generator of liquid metal reactor to avoid sodium-water reaction incidents in the SG. The optimization of steam generator from economic viewpoint is to minimize the total cost of heat transfer area and pumping power. The baffles are primarily used in shell and tube steam generator for inducing cross flow over tube bundles, and as a results, improving heat transfer performance. In this paper a computer based design method, which covers segmentally baffled steam generator is developed for preliminary DWTSG design. And parametric sensitivity studies are done to determine required heat transfer area to meet the specified heat capacity by calculating minimum or allowable shell-side pressure loss.

Purpose: This study was to apply head and neck massage to patients in intensive care unit and to inventigate the effect of that massage on sleep and state anxiety. Method: The subjects in this study were 27 patients who were admitted in medical intensive care unit. The study was performed from June thru September of 2005 on the One-group pretest-posttest design and the sleep, state anxiety of the subjects were measured before and after head and neck massage. For data analysis, paired t-test and Pearson correlation coefficient were utilized. Result: The first hypothesis that the subjects might have a better sleep after being exposed to head and neck massage was accepted. The second hypothesis that the subjects might feel less state anxiety afrer being exposed to head and neck massage was accepted. The third hypothesis that the sleep of the ICU patients maight be correlated to their anxiety was accepted, as there appeared correlation between their sleep and anxiety. Conclusion: Head and neck massage is identified as one of independent nursing interwentions to improve the sleep of ICU patients and ease their anxiety, and it is necessary to apply it to clinical practices.
