Purpose : Despite of development of neonatal intensive care, infections, especially catheter-related infection, have been a major problem in newborns on intensive care. Catheter-related infection is closely related to skin colonization so that skin disinfection is crucial to protect newborns from the infection. Cotton balls of seventy percent alcohol made by hospital frequently open to air so that composition of alcohol may be easily evaporated. We hypothesized that 10% povidone would have better disinfection compared to 70% alcohol and normal saline. Methods : The effect of skin disinfection was evaluated in newborn infants who were admitted to the neonatal intensive care unit(NICU) of Hanyang University Kuri Hospital by a skin swab culture before and after disinfectant exposure. Before skin disinfective preparation, the peripheral intravenous catheter insertion sites were swabbed for culture with sterile cotton moistened with normal saline. Cotton balls of 70% alcohol(Alcohol group, n=20) or 10% povidone and 70% alcohol(povidone group, n=20) were randomly selected. Normal saline swabs were used for controls(n=10). After swabbing, the skin swab culture was done on same sites with same procedure. Results : Before skin disinfection, culture-positivity was shown in 9 of 20 leases of alcohol and povidone groups, respectively and in 8 of 10 cases of the controls. After skin disinfection, culture-positivity was still shown in 3 of 9 cases of the Alcohol group, in 2 of 9 of the Povidone group, and in 6 of 8 cases of the controls. Disinfective effect was significantly different among the 3 groups(p=0.0387). The povidone group had significantly better disinfection than the controls(p=0.0156), but the alcohol group was not significantly different from the controls. Conclusion : The cotton balls of povidone had similar effect of disinfection compared to those of alcohol, but better disinfection than the controls. A disinfective effect of the cotton balls of alcohol was not, however, significantly different from the controls. We suggest that purity of alcohol, quality control of cotton balls of alcohol, and disinfection method should be reevaluated.

We investigated whether two-kinds of mixture (NHDT-1 and NHDT-2) mainly composed of Hovenia dulcis Thunb had beneficial actions for alcohol and acetaldehyde degradation in acute alcohol treatment and liver protection from fatty liver induced by chronic alcohol administration. In acute alcohol degradation experiment, serum alcohol and acetaldehyde concentrations exhibited lower 1, 3 and 5 hours after taking 3 g ethanol per kg body weight in NHDT-1 treated rats, but not NHDT-2 including ginseng. On the contrast to the acute effect on alcohol degradation, the long-term alcohol administration revealed that NHDT-2, not NHDT-1, protected the increase in serum concentration of aspartate aminotransferase, alanine aminotrasferase and ${\gamma}-triglyceride$ metabolism similar to the rats not consuming alcohol, leading to decreased triglyceride accumulation in blood and liver. In liver morphological study, NHDT-1 preserved the regular hepatocyte morphology, decreased fat accumulation and reduced sinusoidal leukocyte infiltration in hepatocytes. In conclusion, NHDT-1 plays an important role in alcohol and acetaldehyde degradation without protecting liver damage while NHDT-2 works as hepatocyte protector from alcohol mediated damage.

Alcohol has as much effect on our lives as the different taste for foods that people have all of the world. Recently, the interest about drinking habits has increased with the rise in health problems for college students with poor health related behavior. The purpose of this study was to evaluate alcohol consumption, smoking and eating behavior of college students in the Kyungsan area. This survey was administered through questionnaires, and the subjects were 177 male and 189 female college students. The self-administered questionnaire was composed of questions concerning social-demographic factors, general characteristics, cigarette smoking, alcohol consumption and eating behavior. The data were analyzed by $\chi$$^2$-test and t-test. According to the survey results, almost of all of the survey subjects drank alcohol. The mean alcohol consumption level per day for male students (33.9${\pm}$29.7g) were significantly higher than for the female students (18.5${\pm}$16.5g), and more than 39.6% of the subjects drank alcohol 1-3 days a week. Alcohol consumption changed the students eating habits. Most students had dietary problems such as fast eating, skipping meal and spending too much money on fast food. The survey about eating behavior of the students showed the male students had more problems when compared with female students. Alcohol consumption levels and alcohol dependence showed a significant positive correlation with smoking cigarettes (r=0.386, p＜0.001). The correlation coefficient between alcohol consumption and eating behavior was negatively correlated with skipping meals (r=-0.121, p＜0.001). However, there were significant and positive correlations with overeating when students were depressed (r=0.130, p＜0.05), with eating meals when watching TV or videos (r=0.085) and with spending money on fast food(r=0.235, p＜0.235). The results indicate that health related behaviors of college students in the present study were fairly good. More attention should be given to college students and their habits of skipping meal, alcohol drinking and smoking, and the fairly good students can act as a model for correct dietary behavior so as to improve overall student health.

The dry cleaning effect related to the type of soil and fiber was analyzed using silicone and alcohol-based solvents(ethyl alcohol, isopropyl alcohol, acetone) that are relatively safe for the human body and environment to improve the detergency of hydrophilic soils in dry cleaning system. Based on this analysis, an effective dry cleaning method to be carried out for improving the detergency according to the type of hydrophilic soils. After dry cleaning was performed using 20 types of artificial soiled fabrics consisting of 7 types of fibers and 4 types of hydrophilic soils, the detergency was measured and the results were compared and analyzed by solvents and fiber types. The results are presented as follows; first, the detergency of hydrophilic soils using silicone solvents showed a low rate of detergency. In particular, the tannin soil showed a lower level of detergency compared to the protein soil. Second, the detergency of hydrophilic soils using silicon solvents with dry soap differed in some detergency according to the soil and fiber types. Especially, the detergency of curry soil on cotton fabric showed significant improvement. Third, the protein soil was not removed from dry cleaning using alcohol-based solvents, but the effect of dry cleaning of curry soil on both cotton and polyester fabric was substantially improved. As a result, the elimination of blood soil is more effective in silicon solvents than in alcohol-based solvents. The removal of tannin soils may improve detergency by adding dry soap to silicon solvents or by using alcohol-based solvents as alternative solvents. The use of alternative solvents such as silicon and alcohol solvents can contribute to the environmental improvement of the dry cleaning industry, which uses petroleum-based solvents. It is also expected to provide consumers with the opportunity to choose eco-friendly and efficient dry cleaning methods.

To evaluate the possible utilization of ginseng by-products, chemical components of ginseng residue, reducing ability of DPPH, effect of residue extract on the yeast growth, amino acid contents of yeast cell, increase of residue extract yield by enzyme treatment were studied. Alcohol and water extract residue contained 43-46% total reducing sugar and 14-15% crude protein, while alcohol extract residue had 0.18% n-BuOH extract. Water extract of alcohol extract residue had about 45% reducing ability of DPPH in comparison with that of alcohol extract from ginseng roots. Essential nutrients for the yeast growth were found in extract when Saccharomyces cerevisiae was cultured in Czapeck medium, a compound medium, with the residue. The addition of residue extract to malt medium, a natural medium, enhanced 30-40% yeast growth. And content of each amino acid in yeast cell cultured on malt medium with ginseng residue extract was much more than that of the cell cultured without ginseng extract, but amino acid composition of yeast cell did not differ from one another. The treatment of alcohol extract residue with cellulase increased 250% yield of residue extract.

Commercialized production of onion vinegar, which has biological activities formed through alcohol and acetic acid fermentation, requires standardization. The objective of this study was to determine optimal conditions of sugar contents ($11{\sim}15^{\circ}Brix$) and agitation rate (100~300 rpm) of fermenter in the alcohol-acetic fermentation for producing onion vinegar. The alcohol and total acidity contents increased, whereas contents of total sugars decreased during alcohol fermentation. Contents of alcohol of 13 and $15^{\circ}Brix$ reactants were about 8% in 36 hr and total acidities of all samples were below 0.2% in 60 hr. During acetic fermentation, total acidity increased with highest value at 9 days (3.2% in 100 rpm), 10 days (4.1% in 200 rpm) and 8 days (4.3% in 300 rpm), respectively. From these results, sugar contents ($13^{\circ}Brix$) were measured for alcohol fermentation and agitation rate (300 rpm) for fast fermentation method of vinegar. The contents of total phenols, flavonoids and quercetin in onion vinegar were 33.3 mg/100 g, 3.0 mg/100 g and 2.0 mg/100 g, respectively. Onion vinegar showed an antimicrobial activity against Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes, Salmonella typhimurium, Escherichia coli and Enterobacter aerogenes. Antioxidant effect of onion vinegar was 26.23% in DPPH radical inhibition and 58.58% in superoxide dismutase like activity, respectively. Fibrinolytic activity was 1.51 plasmin unit/mL in onion vinegar. In conclusion, onion vinegar processed by alcohol and acetic fermentation had nutritional values and potential biological activities.

Phanerochaete chrysosporium is a white rot fungus which secrets a family of lignin-degrading enzymes under nutrient limitation. Ligninase was extracellularly produced in agitated submerged cultures of P. chrysosporium, SC 26. Addition of veratryl alcohol(4 mM), and benzyl alcohol(10 mM) with 0.1% Tween 20 to the culture medium stimulated ligninase production. However, ligninase was not detected when both treatments of veratryl alcohol and benzyl alcohol without Tween 20 were added to the medium. Addition of 0.1 % Tween 20 to the culture medium had little effect on ligninase activity. The ligninase activity was maximum on day 5-8 for veratryl alcohol, and benzyl alcohol with 0.1 % Tween 20 additive medium.

The rates of solvolysis of $cis-[Co(en)_2Cl_2]^+$ complex have been investigated using spectrophotometric method at various pressures up to 1500 bar in several binary-aqueous mixtures(water-methyl alcohol, water-acetone, water-isopropyl alcohol and water-ethylene glycol). The activation volumes obtained from the pressure effect on rate constants were 1.13∼4.44 cm3mole-1 for methyl alcohol, 1.13∼3.59$cm^3mole^{-1}$ for acetone, 0.82∼3.44$cm^3mole^{-1}$ for isopropyl alcohol and 1.13∼2.68cm3mole-1 for ethylene glycol. In case of water-methyl alcohol, in addition to, the rates of solvolysis of this complex were determined in the presence of Fe(Ⅱ) ion and the activation volumes were -0.56∼1.59cm3mole$^{-1}$. The rates of solvolysis of this complex were analyzed by comparing with the results obtained from activation volumes and free energy cycle.
