Purpose: Methicillin-Resistant-Staphylococcus aureus(MRSA) has been increasingly recognized as a cause of nosocomial infection. MRSA is hardly-controllable organism among the pathogen of nosocomial infection, because it is resistant to most antibiotics except vancomycin, and local treatment with most antiseptics are not effective to eradicate MRSA from the infection. The effectiveness of Vacuum-Assisted-Closure(VAC) was reported widely. we tried to modify original VAC. We tried VAC dressing on MRSA infected wound to evaluate whether or not the VAC is effective to eradicate MRSA which existed in the open wound. Methods: From September 2003 to December 2003, 24 patients admitted to the plastic and reconstructive surgery and orthopedic surgery, were studied. All patients were found to be positive in previous wound. Using clinical randomized study, 24 patients were divided into two groups: VAC dressing group and the $Betadine^{(R)}$ dressing group(control). During treatment, wound culture was done twice a week for evaluation of MRSA infection elimination. Results: The mean period that MRSA become not detected in all case was 17.1 days in VAC dressing group, and 25.8 days in control group, respectively. The p value was 0.013. The result reveals that the VAC dressing group is more effective to MRSA infection control. As a result, the VAC dressing was more effective in MRSA infected wound than conventional dressing. Conclusion: Through this study, we found objective result of VAC dressing. We hope that VAC dressing is more widely applied to fresh and infected wound.

Dressing is a seasoned mixture usually used as a stuffing in food. Quality characteristics and antioxidant activity of fruit dressing using lentil legume were investigated. The four groups were divided into D-1(fruit dressing purchased from the local market in Deagu, Korea), D-2 (grapefruit-sugaring dressing prepared with grapefruit sugaring and lentil legume paste), D-3 (vinegar dressing purchased from the local market in Deagu, Korea), D-4 (pineapple-vinegar dressing prepared with pineapple vinegar and lentil legume paste), and then they were analyzed with regard to general compositions, Hunter's color value, mineral and free amino acid content and antioxidant activities. The pH and titratable acidity in all samples ranged from 2.9 to 4.6 and from 0.6 to 1.2%, respectively. The crude protein content were 2.29% for D-2 dressing and 4.03 for D-4 sample, while were not detected D-1 and D-3 samples. In case of Hunter's value, The ' L'and 'a' values of all samples ranged from 45.98 to 56.54 and from -1.59 to 3.30, respectively. The D-4 sample exhibited the higher levels of Ca (215.40 mg/kg), K (1,105.83 mg/kg), Mg (233.63 mg/kg) and Fe (13.78 mg/kg). The levels of heavy metals (As, Pb, Cd and Hg) in all samples were not detected. The contents of total amino acid in D-3 and D-4 samples were 8.269 and 3.419 mg/mL, respectively. The highest contents of total phenols($191.13{\mu}g\;GAE/mL$) and DPPH radical scavenging activity(93.69%, Inhibition) were observed in D-4 sample.

Since they were introduced by Ward in 1923, periodontal dressing have been routinely used following the periodontal surgery to avoid pain, infection, desensitizing teeth, inhibiting food impaction of the surgical areas, and immobilizing injured areas. Recently, however, the value of periodontal dressings and their effects on periodontal wound healing have been questioned, several authors have been reported that the use of dressing has little influence on healing following periodontal surgical procedures. In addition, there is evidence that when good flap adaptation is achieved, the use of a periodontal dressing does not add to patient comfort nor promote healing. The purpose of this study was to evaluate patient postoperative pain experience and discomfort with and without the use of periodontal dressing following periodontal surgery. Twenty-eight patients, 11 male and 17 female. were selected for this study; The age range was 31 to 56, with an average of 40.2years. Patient selection was based on existence of two bilateral sites presenting similar periodontal involvement, as determined by clinical and radiographic assessment, and requiring comparable bilateral surgical procedures. Using a splitmouth dressing. one site received a periodontal dressing while the other site did not. Pain assessment was made according to a horizontal, rating scale(0-10). After at least a two-week period, the second surgical precedure was performed using the alternate postoperative treatment. At the conclusion of the trial, a self-administered questionnaire on postoperative experience was administered, and were asked of their preference of either, dressed or undressed. The results were as follows: 1. A similar trend for mean pain and discomfort scores as assessed by patients both dressed and salinetreated procedures was evident during 7-day postsurgical period. 2. Statistical analysis of differences between the dressed side and salinetreated side with respect to pain, discomfort and patient's experiences revealed that both treatment sides behaved similarly at any postoperative day(P>0.05). 3. Considering the patient's preference, on the basis of pain and discomfort experienced, 43% preferred the saline-mouthwash and 32% preferred the dressing, 25% showing no preference for either the dressing or the saline-mouthwash. There is evidence to support the use of a periodontal dressing in retention of an apically positioned flap by preventing coronal displacement, or its use to provide additional support to stabilize a free gingival graft. However, there will always be a use for periodontal dressing although routine use of dressings may decrease because of better surgical techniques and the use of antibacterial mouth rinses.

Through the previous works, it was found that the laminated grinding wheel is more efficient to generate smoother surface in short time than general grinding wheels. But, if the laminated grinding wheel is easily worn-out, it is impossible to apply this wheel in the real grinding process, because the periodic time for dressing is closely linked to the productivity of the process. So, it is required to investigate the wear of the laminated grinding wheel fer studying the periodic time for dressing. But it is difficult to analyze the dressing period quantitavely. Therefore, in this study, periodic times for dressing of the laminated grinding wheel and general grinding wheel are deduced from the relationship between the wear of grinding wheels and the surface roughness changes according to the number of traverse in cylindrical traverse grinding through experiments. This study shows that there are some differences in the wheel wear mechanisms between the general and laminated grinding wheels. As a result, it is also found that the periodic time for dressing of the laminated grinding wheel is longer than that of the general grinding wheel.

Pompholyx is a special vesicular type of hand and foot dermatitis. It is an acute, chronic or recurrent dermatosis of the fingers, palms and soles, characterized by a sudden onset of many deep-seated pruritic clear vesicles. We diagnosed a patient with pompholyx as damp heat and treated with wet dressing by gauze soaked in distilled solution of Gamihwangryunhaedok-tang(Jiaweihuanglianjiedu-tang). After treatment with wet dressing, we observed the improvement. Based on this study, it is considered that wet dressing with Gamihwangryunhaedok-tang(Jiaweihuanglianjiedu-tang) can be applied to the treatment of pompholyx.

With a purpose of finding out the effects of magnesium and boron enriched organic-compound fertilizer application on qualities of grasses on the hilly pasture, a field experiment was arranged with five different treatments as a randomized block design and lasted from September, 1984 to the end of growing season in 1986. The results obtained are summarized as follows: 1. Mean chemical components except NFE of grasses at the plots with organic-compound fertilizer application were appeared to contain slightly high comparing to single dressing. 2. Production of DCP with organic-compound fertilizer (1,170.2 kg/ha) was significanty increased by 20% comparing to single dressing (975.7 kg/ha) in the conventional fertilization level (p<0.05), but it was not significantly different between them in the low dressing level. 3. Production of energies (TDN, StE and NEL) with organic-compound fertilizer of low and conventional dressing level were appeared to increase by 10 and 13 to 15% than those of single dressing of the same levels, respectively. But it was not significant difference. 4. Like single dressing nutrient productions with organic-compound fertilizer were appeared significantly high due to increasing of dressing gradually (P<0.05-0.01) 5. Mineral contents of P and Mg at the plots with organic-compound fertilizer were a little higher, on the other hand, K, C/P and K/Ca + Mg equivalent ratio were slightly lower than those of single dressing, but the content of Ca tended to similar between them.

The effect of vinegar concentration (＋30%, 0% and -30%) on the emulsion stability of mayonnaise dressing was studied by the measurement of theological test and sensory evaluation. The emulsion stability of mayonnaise dressing increased with increase in vinegar concentration. The results of steady shear theological test indicated that C sample of the highest vinegar concentration (＋30%) exhibited higher emulsion stability than other samples. The dynamic shear datas were similar to steady shear theological data. The mayonnaise dressing samples showed time dependence, which was quantitatively described by the Weltman model. Parameters A and B indicated that the structure of C sample exhibited more stable than that of A (-30%) and B (0%) samples. The amount of oil separation was less than that of A and B samples. The results of sensory evaluation were similar to those of theological and emulsion tests.

Purpose: Iodine has been used for the prevention or management of wound infection as a topical agent. Although iodine was widely used mainly by Betadine$^{(R)}$ and cadexomer iodine, there was no comparative study on the efficacies of dressing methods of iodine. And also it's wound healing effect was not yet clear. The purpose of this study is to compare antibacterial effects and wound healing effects associated with various dressing methods of iodine on infected full thickness skin defect in the mouse. Methods: One full thickness skin defects in the mice (n=60) were developed on the back and left open for twenty-four hours. Sixty mice were divided into four groups : group S (dressing with Betadine$^{(R)}$ soaking, n=15), group T (dressing with Betadine$^{(R)}$ topping, n=15), group I (dressing with Iodosorb$^{(R)}$, n=15), group G (control group, dressing with dry gauze, n=15). The size of the wound defects and the grades of wound healing were evaluated in 4, 7, 10 days, and antibacterial effect was evaluated with restricted zone in Mueller Hinton agar by disk diffusion method. Results: After the wound was left open for twenty-four hours, many Staphylococcus aureus were cultured. The wound defect size was decreased in order of Betadine$^{(R)}$ soaking, Iodosorb$^{(R)}$, Betadine$^{(R)}$ topping and gauze dressing group in all days, but difference among experimental groups was not statistically significant. The grade score of wound healing was increased in order of Betadine$^{(R)}$ soaking, Iodosorb$^{(R)}$, Betadine$^{(R)}$ topping and gauze dressing group, and the difference was statistically significant. Antibacterial effect for S. aureus was increased in order of Iodosorb$^{(R)}$, Betadine$^{(R)}$ soaking, Betadine$^{(R)}$ topping and gauze dressing group, and the difference was statistically significant. Conclusion: Selection of the effective dressing method of iodine for infected wounds remains a controversial decision. According to this study, Iodosorb$^{(R)}$ may be most effective method for antibacterial effect and Betadine$^{(R)}$ soaking may be most effective method for infected wound healing. However, further study is necessary to evaluate the clinical efficacy of dressing methods of iodine and to search for the mechanisms that explain their effects.

다수확 비료체계의 확립을 위하여 추비기 및 추비바업이 소맥의 수량요인에 미치는 영향에 관하여 시험한 결과를 요약하면 다음과 같다. 1. 배비구는 보비구에 비하여 수수 1수립수 및 수량이 높았으나 통계적 유의차는 보이지 않았다. 이는 저온 건조한 기상조건으로 말미암아 비료의 흡수 소화가 원활하지 못하였기 때문일 것이다. 2. 질소추비량의 1/3을 출수기에 토양시비 한 것은 6～7% 감소되었다. 3. 질소추비량의 1/3을 출수기에 요소엽면산포한 것은 4～6% 증수하였으며 1수립수와 천립중이 증대되었다. 4. 추비시기는 3월중하순이 가장 증수되었다. 유효경비율과 수중이 훨씬 크고 간장, 수장, 수수, 1수립수 및 천립중도 약간 컸다.
