The purposes of this study were to develop a tool for assessing internal branding performance and to identify the difference of internal branding performance between local and international hotels. The internal branding performance measure was developed through literature studies and face-to-face in-depth interviews with managers in various departments of 5 deluxe hotels. The questionnaires were distributed to 460 employees in food and beverage departments of 11 deluxe hotels in Seoul, and a total of 398 questionnaires were used for analysis ($86.5\%$). The statistical analyses were completed using SPSS Win (12.0) for descriptive analysis, reliability analysis and t-test, and AMOS (5.0) for confirmatory factor analysis. The results of this study showed that the measure developed in this study was reliable and valid for assessing internal branding performances of hotels. In addition, the internal branding performances of hotels were high at understanding of brand dimensions and relatively low at work and organizational culture and human resource management dimensions, and local hotels showed lower levels of performance than international hotels at the dimensions of work and organizational culture (t = -3.801, P < 0.001) and human resource management(t = -5.397, p < 0.001). In conclusion, it is considered that a strong internal branding strategy should be established for successful brand management, and the practical measure for internal branding performance would be a key factor.

Endocrine disruptors are chemicals which can be found in our normal daily life. They can be easily ingested through plastic food containers, pesticides, etc. They include DDT, bisphenol A, benzophenone and phenylphenol, etc. Endocrine disruptor can be very harmful and toxic because it disrupts the normal function of the endogenous endocrine system. It has been reported that endocrine disruptor can cause the fatal strike in reproductive system central nervous system and the other part of the body. We have examined if the growth of lactic acid bacteria could be resistant to the endocrine disruptor. We have used Lactobacillus delbruekii as an experimental strain and benzophenone and phenylphenol for the comparison purpose. Experiments included the evaluation of turbidity, absorbance and actual cell counts. Although Lactobacillus delbruekii showed the higher resistance to benzophenone than phenylphenol it was still resistant to both benzophenone and phenylphenol. Because the experimental concentrations of benzophenone and phenylphenol were so high to compare with the actual concentration we meet in daily life, Lactobacillus delbruekii was considered to be sufficient to survive in the environmental concentration of these endocrine disruptors. This study should contribute to the development of fermented beverage with beneficial effect by lactic acid bacteria.

The purpose of this study was to evaluate alcohol consumption and nutritional status in patients with alcoholic liver disease. The subjects were 80 patients with alcoholic liver cirrhosis and 12 patients with alcoholic fatty liver. Also 57 alcoholics without liver disease, 32 patients with viral liver cirrhosis and 194 normal men were included as control groups. Data on anthropometric index, socioeconomic status, alcohol consumption, dietary habits and dietary intakes were collected by individual interview. Alcoholic liver disease group had significantly lower triceps skinfold thickness and mid-uppr-arm circumferences than other groups. Socioeconomic status of alcholoci subjects was middle class or lower than that. The amount, duration and frequency of alcohol consumption were significantly higher and the quality of side dishes consumed with alcoholic beverage was significantly poorer in patients with alcoholic liver cirrhosis than others. Patients with alchololic liver disease ingested approximately 40% of daily caloric intake as alcohol and all alcoholic subjects had lower average intakes of protein, carbohydrates, fat, vitamins and minerals as compared with Korean adult average intakes. The results suggest that alcohol and poor dietary intake could cause malnutrition and might be two of the important risk factors to develop alcoholic liver disease in alcoholics. But other factors like genetic and immunological factors should be also considered in elucidating the causes of alcoholic liver disease. An extensive nutritional education should be emphasized for alcohol consuming population to prevent development of alcoholic liver disease.

With the goal of searching for the ways to help market traditional beverages as take-out products, this study conducted a survey over men and women over 20 years of age in Seoul and Gyeonggi Province. Their perceptions of importance in choosing traditional beverages and conventional drinks were examined for difference. As a result, taste, reliability, health, flavor, and price were important at general beverage, while taste, health, flavor, reliability, price, and color were in choosing traditional beverages. The participants mentioned recovery from fatigue as the most favorable added feature of traditional beverages, which was followed by beneficial for adult diseases and facilitating digestion. Their preferences toward using them to satisfying a sense of hunger was relatively low. The participants preferred price range was $3,000{\sim}3,500$ won, their favorite ingredients were functional ones, and their favorite shop design was a traditional style. It seems that the marketability of traditional beverages as take-out products is high. The promotion and development efforts should involve marketing to women, differentiation strategies from other drinks, a graceful image, reliable drinks, and additional functions such as recovery from fatigue and can benefit adult diseases.

The purpose of this study was to identify the factors, which influence impulsive buying at duty-free shops. This involved an investigation into the effects of demographic characteristics, the types of purchased items, and the situational and emotional factors affecting impulsive purchasing behaviour in consumers, who had bought items from duty free shops in the past three years. The findings are as follows. Firstly, while beverage and cosmetic items were found to encourage impulse buying, in general demographic variables and type of product had only a slight influence. Secondly, the situational factors of price benefits, overseas luxury branding, and ease of access in the duty free shopping area all had a definite positive influence. Thirdly, with regard to emotional factors, positive emotion was found to have strong augmenting effect on impulsive purchasing. The findings can be used in the development of educational materials to prevent impulsive purchasing and promote sensible consumer behaviour.

Aluminum liners used in cylinders are hazardous for human health. In this study, we use a plastic PA liner inside cylinders to solve this problem. Plastic PA liners are widely used in the manufacturing industry in the production of food and beverage containers. We covered the aluminum boss with a plastic liner material and wound the composite fibers over the liner material. To reinforce the dome area, we used low strength / high elongation plastic liner. To predict the performance of the developed product, we conducted structural analyses utilizing the 3D laminated solid element. We verified the soundness of the product by testing the prototype.

Purpose: Makgeolli is a traditional alcoholic beverage made from rice with a fermentation starter called "nuruk." The concentration of alcohol in makgeolli depends on the temperature of the fermentation tank. It is important to monitor the alcohol concentration to manage the makgeolli production process. Methods: Data were collected from 84 makgeolli fermentation tanks over a year period. Independent variables included the temperatures of the tanks and the room where the tanks were located, as well as the quantity, acidity, and water concentration of the source. Software for the multilayer perceptron model (MLP) was written in Python using the Scikit-learn library. Results: Many models were created for which the optimization converged within 100 iterations, and their coefficients of determination $R^2$ were considerably high. The coefficient of determination $R^2$ of the best model with the training set and the test set were 0.94 and 0.93, respectively. The fact that the difference between them was very small indicated that the model was not overfitted. The maximum and minimum error was approximately 2% and the total MSE was 0.078%. Conclusions: The MLP model could help predict the alcohol concentration and to control the production process of makgeolli. In future research, the optimization of the production process will be studied based on the model.

The surfaces of different-sized endosperm, bran, and husk rice powders were modified using carboxymethylation. Carboxymethylation was carried out using aqueous alkalization and neutralization. After the carboxymethylation process, the centrifuged products were milled and classified by size: particles passed through sieves of 45, 106, and $300-{\mu}m$ width. The effect of carboxymethylation on physical properties such as solubility and dispersibility of endosperm, bran, and husk particles were studied. Overall, carboxymethylation increased solubility of the particles, while size reduction increased dispersibility. In particular, carboxymethylation created good aqueous suspensions by minimizing interparticle agglomeration. Our results show that the combination of size reduction and carboxymethylation improves solubility and dispersibility, resulting in better stability of the suspension. This study may be helpful for expanding the use of rice and its byproducts as ingredients in a variety of food and beverage applications.

A survey was conducted to investigate consciousness of middle and high school students unsing fast food restaurants in Kwang-ju, from July 20 to August 20 in 1993. The results are follows; 1. There are many motives which drive students into fast food restaurants. Among those are its convenience as a place of meeting friends, pleasant and clean environment for eating, no time limit of staying there, hygiene of dining equipment and table ware. 2.The majority of the students used the fast food restaurants between 12:00 and 14:00 pm. It shows that time does not influence much on using there, because they answered in high percent that they use at any time. 3. Student usually pay individually and in some cases their friends or parents pay the bill. 4. Major factor in fast food selection was their tastes, nexts, were proper price, nutrition, and so on, They prefer their home food to restaurants fast foods. 5. The most of students have positive response to make traditional Korean foods into fast foods. The students, in particular, emphasized for the development of traditional Korean foods ; Sikhae and Sujonggwa(beverage), Docbokki, Japchae, kinds of rice cake and Jun. 6. Students suggested to be better fast food service, such as lowering the price, increasing the portion size and developing fast foods from the traditional Korean foods.
