1. There two parts of alcohol's metabolic system the first one is alcoholdehydrogenase(ADH), and second is microsomal ethanol oxidizing system(MEOS). 2. Alcoholic cirrhosis(fibrosis) leads from cytotoxin, malnutrition, and immunue reaction. 3. In the Oriental medical point of view alcohol has strong heat and toxin, which can cause judal, ju-ka, ju-beack, ju-juck, and ko-chang in other words these means that it can cause hepatasis, fatty liver, fibrosis, and liver cirrhosis. 4. About the Liver cirrhosis(fibrosis) pathological system, in the oriental medical point of view, it effects the liver, kidney and spleen which causes Uy-heulGin-guk(瘀血 積), seup-yeul ne-oun(濕熱內蘊), and in the long term it can cause kansinyumhu(肝腎陰虛), kanbeyumhu(肝脾陰虛). Because of the expand of alcohol liver disease, in the future there must be more studies about these disease in Oriental medicine point of view.

Cetostearyl alcohol has been incorporated into cosmetic or pharmaceutial emulsions to give them an appropriate consistency and a long term stability. It is well known that cetostearyl alcohol forms a gel phase with a nonionic surfactant in an aqueous system, and the properties of the gel phase depend on several factors such as the ratio of fatty alcohols. The aim of the present Paper is to investigate the effect of the structural difference of the lipophilic part of surfactants on the stability of the gel phase in the nonionic surfactant / cetostearyl alcohol / water ternary systems using differential scanning calorimeter. It is concluded that the gel phase formed by the surfactant having the bended alkyl chain is more unstable than that formed by the case of the straight alkyl chain, and we discussed the reason why the former is more unstable after long term storage by means of the measurements of the ${\Delta}$H.

Makgeolli is a traditional cloudy-white Korean rice wine with an alcohol content of 6~7%. The present study investigated the morphological characteristics, carbon-utilizing ability, fatty acid composition, alcohol resistance, glucose tolerance, and flocculence of Saccharomyces cerevisiae Y98-5 and Pichia anomala Y197-13, non-S. cerevisiae isolated from Nuruk, which is used in brewing Makgeolli. Similar morphological characteristics were observed for both isolated wild yeast strains; and the carbon source assimilation of Y197-13 differed from that of other P. anomala strains. Strain Y197-13 was negative for D-trehalose, mannitol, arbutin, I-erythritol, and succinic acid. The major cellular fatty acids of strain Y197-13 included C18:2n6c (33.94%), C18:1n9c (26.97%) and C16:0 (20.57%). Strain Y197-13 was Crabtree-negative, with 60% cell viability at 12% (v/v) ethanol. The flocculation level of strain Y197-13 was 8.38%, resulting in its classification as a non-flocculent yeast.

In this work, we fabricated liquid crystal (LC) emulsions with fatty alcohol in order to stabilize high content ceramide in cosmetic formulation. We investigated the role of fatty alcohol and surfactant in the formation of higher order structure. As a result, we found that they play a crucial role to form higher order structure. SAXS study shows that ceramide can be incorporated up to 3% in cosmetic formulation with higher order structure and its stability was maintained up to 12 weeks at room temperature. According to WAXS study, the higher order structure can suppress the re-crystallization of ceramide in cosmetic formulation. Finally, we performed in vivo skin barrier recovery test for the damaged skin. LC emulsions with ceramide and O/W emulsions show significant effect in skin barrier recovery at D 1, D 2 and D 6 compared to the untreated condition. While only LC emulsions show significant skin recovery effect at D 14. We expect that LC emulsions are the promising skin carrier to stabilize ceramide and LC emulsions with ceramide can improve the skin barrier function.

Purpose: This study was conducted to estimate the prevalence rate, and related factors,of fatty liver in male industrial workers. Method: Fatty liver was diagnosed using ultrasonography. The data for abdominal ultrasonography, BMI, smoking, alcohol drinking, exercise, liver enzymes, and lipid profiles were collected in 4,604 male who were examined with a health screening program in 2005. Prevalence rate and associated factors of fatty liver were analyzed using SPSS v. 12.0. Results: Overall prevalence of fatty liver was 34.1% and higher in the 30-39 year male group. Age, body mass index(BMI), hypertriglyceridemia, hypercholesterolemia, HDL cholesterol, r-GTP level were independently associated factors with presence of fatty liver in logistic regression analysis. Conclusion: The prevalence of fatty liver and tendency of associated factors were similar to those in the western world. To prevent development of this hepatic disorder, which may result in end-stage liver disease, risk factors such as obesity and dyslipidemia must be monitored and controlled within normal levels. The results of this study suggested maintenance of a healthy lifestyle, including diet, exercise, and behavioral change, as fundamental rehabilitation nursing implications.

Objectives: This study was performed to examine nutrition problems and causes/contributing risk factors. Methods: This study was conducted using data 1,863 adults visited Asan health screening & promotion center located in Seoul, Korea during May to June of 2013. We used Nutrition Care Process Model developed by the International Dietetics & Nutrition Terminology (IDNT). Results: The most frequent nutrition problem in male subjects was excessive alcohol intake. Men in fifties showed the highest rate of excessive alcohol intake among the age groups examined (22.4%). By comparison, the most frequent nutrition problem in women was inadequate protein intake. Women in fifties exhibited the highest rate of inadequate protein intake (22.5%). The most common contributing factors for these observations were a low preference for dairy products followed by high preference for alcohol and a deficit in food-and nutrition-related knowledge, regardless of the sex and age. The most common nutrition problem observed among the group diagnosed with hyperglycemia or hypertriglyceridemia or hyperuricemia or fatty liver was excessive alcohol intake (p < 0.001), whereas the group diagnosed with hyperglycemia or hypercholesterolemia showed significantly higher rate of inappropriate intake of carbohydrate (fructose) compared to the group not diagnosed with such disease conditions (p < 0.05). The group diagnosed with hypercholesterolemia, hyperuricemia and fatty liver showed significantly higher occurrence of inappropriate intake of fat (saturated fat) than the group free of such diseases (p < 0.001). The osteopenia group showed higher rate of inadequate protein intake (p < 0.001) and the fatty liver group with excessive energy intake (p < 0.001). Overall, the results suggest that there is a significant relationship between nutrition problems and health conditions found in groups diagnosed with a diverse array of medical conditions. Conclusions: Therefore, we strongly suggest that dieticians should implement nutrition interventions with people visiting health screening & promotion center based on nutrition problems and the contributing factors diagnosed by dietitions in order to prevent chronic diseases in this population.

Solder paste is widely used as a conductive adhesive in the electronics industry. In this paper, nano and microsized mixed lead-free solder powder (Sn-Ag-Cu) is used to manufacture solder paste. The purpose of this paper is to improve the storage stability using different types of solvents that are used in fabricating the solder paste. If a solvent of sole acetate is used, the nano sized solder powder and organic acid react and form a Sn-Ag-Cu malonate. These formed malonates create fatty acid soaps. The fatty acid soaps absorb the solvents and while the viscosity of the solder paste rises, the storage stability and reliability decrease. When ethylene glycol, a dihydric alcohol, is used the fatty acid soaps and ethylene glycol react, preventing the further creation of the fatty acid soaps. The prevention of gelation results in an improvement in the solder paste storage ability.
