This review focused on the pharmacological treatment of alcoholism, especially alcoholism-related mental disorder. The pharmacological agent for alcoholism can be divided into the following categories : anticraving agent, aversive agent, agent to treat acute alcohol withdrawal, agent to diminish drinking by treating associated psychiatric pathology, agent to induce sobriety in intoxicated individuals. Following trends are included in new trends of pharmacological treatment of alcoholism. What are precise conditions amenable to pharmacological intervention? ; How can psychosocial and behavioral intervention be integrated with pharmacotherapy to enhance treatment outcome? ; Is the concept of "matching" specific pharmacotherapy treatment to different aspect of alcoholism more efficacious than a more generalized medicational approach to treatment? One of the most important factors for alcoholics treatment is good and proper therapeutic relationship with patients and setting up individually specialized treatment program is also important.

A series of proton conductive composite membranes based on poly(vinyl alcohol) and phosphosilicate gels powders were successfully prepared. The proton conductivity of these composite was attributed to the phosphosilicate gel, which derived from tetraethoxysilane and phosphoric acid by sol-gel process at a molar ratio of P/Si = 1.5. The proton conductivity increased with increasing both the content of phosphosilicate gel and relative humidity. Temperature dependence of conductivity showed a Vogel-Tamman-Fulcher type behavior, indicating that proton was transferred through a liquidlike phase formed in micropores of phosphosilicate gel. The high conductivity of 0.065 S/cm with a membrane containing 60 wt$\%$ of the gel was obtained at $60^{\circ}C$ at $90\%$ relative humidity.

Dopamine reward pathway projecting from ventral tegmental area to nucleus accumbens is well known as playing an important role in alcohol dependence. It is supposed that this dopamine pathway is modulated by $5-HT_3$ nervous system, and it was reported that ondansetron (OND), $5-HT_3$ receptor antagonist, reduced drinking amount and increased abstinence rate in alcohol-dependent patients. The purpose of this study is to investigate the effect of combination of OND and naltrexone (NTX), non-specific opioid receptor antagonist, on alcohol intake in C57BL/6 mice. In 40 C57BL/6 mice in the state of alcohol dependence, vehicle, while OND 0.01 mg/kg, or NTX 1.0 mg/kg administrated respectively, or OND 0.01 mg/kg and NTX 1.0 mg/kg administrated simultaneously for ten days, medication effects on 2-hr alcohol, 22-hr water, 24-hr food intake and body weight were studied. When vehicle group was compared with 3 medication groups respectively, using a repeated measure ANOVA, NTX alone and vehicle groups showed a significant medication by time interaction (p=0.042) in 2-hr alcohol intake, but in the other 2 groups, OND and NTX combination group and OND alone group, there was no significant interaction with vehicle group in 2-hr alcohol intake. From these results, it is suggested that there is no effect on alcohol intake in mice treating with OND, and naltrexone#s suppression effect on alcohol intake in mice is attenuated when treating with OND and NTX simultaneously. It is supposed that a further study looking at the interactions of serotonin, dopamine and opioid nerves systems will be needed.

The purpose of this study was to investigate the relationship between alcohol use and drinking problems among college students. Data were collected by structured questionnaires from 400 college students by convenient sampling methods from September 26 to October 14, 2011. Data were analyzed by SPSS/WIN 15.0 program. The results were as follows: According to the Alcohol Use Disorder Identification Test (AUDIT), subjects were classified into four groups such as 40.2% of no problem, 36.7% of drinking problem, 6.8% of high risk drinking problem and 16.3% of alcohol dependence. The alcohol use and drinking problems were significant difference for gender, age, type of residence, age of first drinking, cause of drinking, frequency and amount of drinking. The alcohol use was correlated with drinking problems: social function impairment(r=.601, p<.01), behavior problem(r=.579, p<.01), family and interpersonal impairment(r=.637, p<.01). The influencing factors of drinking problems were alcohol use(${\beta}$=.640, p=.000). This study concludes that it is necessary to establish alcohol use policies on campus and develop temperance education program to reduce alcohol consumption and drinking problems.

Purpose: This study aimed to identify the level of knowledge on preventing cardiovascular disease (CVD) and nicotine dependency among smoking male college students, and to examine the predicting factors of nicotine dependency. Methods: This study was conducted as cross-sectional descriptive research using structured questionnaires. Data were collected from 411 smoking male college students ($22.5{\pm}2.59$ yr) at two universities located in two cities in Korea from September 2012 to April 2013. Logistic regression analysis was performed to estimate age-adjusted odds ratios of nicotine dependency. Results: The mean value of nicotine dependency was $4.2{\pm}1.96$ and the percentage of participants who had strong nicotine dependency (${\geq}7$) was 10.7%. Logistic regression analysis showed that, when adjustment was made for age, nicotine dependency was predicted by the frequency of alcohol drinking (${\geq}3$ times/week), knowledge on CVD prevention, the age starting drinking, and the total length of smoking. Conclusion: Nicotine dependency was strongly related to the frequency of drinking alcohol and lower knowledge on CVD prevention. Therefore, male college students who have a dependent smoking habit and drink alcohol frequently need to take more interest in health through educational counseling to modify their lifestyle behaviors and to have preventive knowledge related to CVD.

Korea, which has a high dependency on energy imports, is greatly affected by fluctuations in international oil prices. In order to offset these effects, various policies such as 'diversification of energy sources' and 'energy mix' are being pursued. Renewable Fuel Standard (RFS) is a policy promoted for this purpose, and a compulsory mixing system is applied only to the diesel. In order to reduce dependence on fossil fuels in various countries, they are concentrating on the dissemination of bio-alcohol as well as bio-diesel, and commercialization through various verification. In this study, evaluation of domestic materials and vehicles was carried out to promote domestic bio alcohol fuel. We analyzed the fuel characteristics of domestic quality standard items by mixing them with gasoline of automobile at a certain mixing ratio (0%, 3%, 6%, and 10%).

Stereochemical course of the reductive decyanation of two stereoisomeric 4-t-butyl-1-phenylcyclohexanecarbonitriles 3 and 4 using solvated electron has been studied. While sodium-mediated reactions of both 3 and 4 in the presence of alcohols give the same ratio, 1.5 : 1, in favor of the thermodynamically more stable product 5 over the other one 6, the ratios obtained from the potassium-mediated process are found to be very sensitive to the kind of H-donors. When reactions are performed without H-donors, 5 is only obtained from the experiments with both stereoisomers irrespective of the metal species.

Previous studies reported that the N-methyl-D-aspartate (NMDA) receptor is related to alcohol dependence in terms of developing withdrawal or tolerance, however, it is controversial whether NMDA receptor antagonists are effective in preventing relapse in alcohol-dependent patients or not. The purpose of this study was to investigate the effect of memantine, an NMDA receptor antagonist, on alcohol intake in C57BL/6 mice, which prefer drinking hereditarily. Using limited access procedures in C57BL/6 mice in the state of alcohol dependence, vehicle, naltrexone 1.0 mg/kg or, memantine 5, 25, or 50 mg/kg i.p. was administered respectively for twelve days. Medication effects on 2-hours alcohol, 22-hour water, and 24-hour food intake and body weight were studied. Using repeated measure ANOVA, the naltrexone 1 mg/kg, memantine 5, 25, or 50 mg/kg, and vehicle groups showed significant medication by day interaction (naltrexone, df=4, F=11.827, p<0.01, memantine 5 mg/kg, df=4, F=7.999, p<0.01; memantine 25 mg/kg, df=4, F=6.199, p<0.05; memantine 50 mg/kg, df=4, F=10.522, p<0.01) in 2-hour alcohol intake. In 3 memantine groups, there was no significant medication by day interaction with the vehicle group in 22-hour water intake, 24-hour food intake, or body weight. The naltrexone and vehicle groups showed significant medication by day interaction in body weight, but not in 22-hour water or 24-hour food intake. From these results, it is suggested that memantine treatment can affect alcohol intake in mice. Therefore, it is possible that a pure NMDA receptor antagonist is effective in preventing relapse in alcohol-dependent patients.
