This study reviews the scientific management theories and discusses those theories within the food service industry. By providing the principles and the practical implications of the theories on the food service industry, this study tries to identify their philosophies and usefulness to the industry so that the managers in the industry use them in their dylmanic operations. In the fastly changing modern globalized world, we now face a situation where it's becoming more and more difficult to mange a restaurant business. In order to build a food industry business that can maintain a continuous development in today's business environment, one will have to apply the professional management theory in a cost-reduce strategy. It is more important though to have managers, organization members, in short, any person who can work to be motivated in accomplishing these two major issues-income increase and cost reduction. In this erawhere it's getting so difficult for researches on possible strategies for these business managers to overcome their difficulties. It is for certain that in the upcoming second millenium the travel and tourism industry will be one of the world's biggest industry worldwide. Korea's hotel industry has developed since the 1988 Seoul Olympic Games and has shown great amount of competition within the same business. Thus managers have become acquainted with the "know-how" strategy and the practical and scientific managemnet theories were introduced. This helped not only to increase income but also to maximize profit. However, rather than concentration on the "Hard-ware" aspect "Soft-ware" related professional management strategies were developed along with professionalism and human service were emphazied. As such, the actual cost of food and beverages are for the hotel industry business managers the biggest shortterm expense item. Due to the natural state of food items, there is a great chance of "Loss" in preservance, and this is the reason it is complicated to effectively maintain food. As a consequence, very often, the failure to managea hotel or restaurant depends on the capability of the food and beverage preservance mangement: on how they are able to manage effectively the original price of food and beverage. Finally, the main problem of the original price management of food and beverage in Korean hotels are: a) No fixation of set price b) The difficulty to calculate the price difference between a set price and an original price. c) Lack of professinalism in managing the food and beverage original price. d) Lack of perception of the highest ranking management personnels. So as to reform these matters it is necessary to : a) Reform on the management accounting system b) Emphasize to the people in charge on the idea of original price management c) Reinforce original price mangement prevention and assurance of indepedent inspection rights d) Reat manpower

This study examined the differences of importance and performance perception level among the food & beverage festival attributes of visitors participating 'Daegu Chimac Festival' and also conducted importance-performance analysis (IPA) of food & beverage festival Attributes. The results were as follows: firstly, food & beverage festival attributes were grouped into four factors such as 'sanitation environment', 'food taste and variety', 'food quality and supplementary service' and 'food purchase convenient.' Secondly, the 4 factors and 21 items of festival attributes showed statistically significant differences in their levels of importance and performance. Finally, results of the questionnaire survey of 322 visitors at '2018 Daegu Chimac Festival' indicated that 'food purchase convenient' and 'food taste and variety' were important to visitors and had high performance. Although attributes related to 'food quality and supplementary service' had an low importance and low performance, and also 'sanitation environment' had an low importance and high performance in the IPA results, they were identified as the key determinants affecting food & beverage festival' success.

The objective of this study was to develop a functional vinegar beverage using yacon roots, and examine the components' changes during fermentation. The alcohol fermentation was conducted by inoculation of Saccharomyces cerevisiae into yacon root juice with sugars. After 10 days of fermentation at $27^{\circ}C$, yacon wine contained 13% alcohol and $7.8^{\circ}Brix$ sugar contents. The yacon wine at 5% alcohol was fermented by Acetobacter aceti(KCTC1010) with 250 rpm agitation rate at $29^{\circ}C$ for 12 days. The acidity of yacon vinegar reached 4.4% after 12 days' fermentation. Statistically (p<0.05), the amount of Acetobacter aceti, pH, alcohol, with total polyphenol content of samples decreased with acidity, whereas individual sugar contents increased. Furthermore organic acids, total sugar, phenolic acids content, total antioxidant capacity, and color were not different among the five samples. The yacon vinegar beverage was prepared with high fructose syrup through the dilution of yacon vinegar. After making the yacon vinegar beverage, the pH, acidity, total sugar, and total microbial content were examined every week over 4 weeks' storage. There were no changes in the samples during that time.

Dongchimi as a Korean traditional fermented food was studied for the possibility of developing into as an ion beverage. Reverse osmosis process was applied to the concentration of dongchimi juice in this study. Dongchimi was prepared at different concentrations of salt and fermentation temperatures. Mineral components of concentrated dongchimi juice were analyzed and compared with those of ion beverage products. The changes of sugar contents and mineral contents were studied depending on different fermentation temperatures, periods and salt concentration. The amounts of mineral components such as $K^{+},\;Mg^{2+}\;and\;Ca^{2+}$ were increased during fermentation but slightly decreased in the last period. It was found that the concentrated dongchimi juice could be used as an improved ion beverage in future, since the electrolytic dissociation components were much more in the concentrated dongchimi juice than those in the existing ion beverages.

Although Korea has just passed the IMF intervention, the hotel business in Gyeongju does not seem to entirely recover from the econmic recession. In particular, the sales of food and beverage dominantly on domestic demand are still in difficulty. This research was undertaken in order to identify the problems of food control in the five-star hotels in Gyeongju area, and to recommend some suggestion of enhancing the current system to boost the revenue. It is revealed that most of the hotels in question are poorly operating for the food control. In particular, they have spent too much unnecessary cost for the ordering, inspecting, issuing and storing food. A five-star hotel is selected for the survey, and the data obtained from the survey are properly manipulated for the analysis. The problems of the food control system are as follows : Firstly, it hasn't developed a standardized manual for the ordering, inspecting, issuing and storing food. Secondly, an appropriate food control system incorporating the unique Gyeongju environment should be developed. Thirdly, 'first ordered, first issued' method should be applied to reduce to reduce the cost Lastly, few managers recognizes the importance of food control.

In this study, we aimed to develop a fermented green rice beverage with a unique flavor and physiological function activity. With glutinous green rice and rice nuruk as independent variables, we modeled the antioxidant characteristics and α-glucosidase, α-amylase inhibitory activity of glutinous green rice fermented beverage to verify its significance. The total flavonoid content and α-glucosidase inhibitory activity were selected as Quadratic models, and DPPH radical scavenging ability and α-amylase inhibitory activity were selected as linear models. For the sensory characteristics of glutinous green rice fermented beverage, sweetness, sourness, savory taste, bitterness, throat feel, nuruk scent, and overall preference increased in preference as the amount of glutinous green rice and rice nuruk increased, but significantly decreased after the center point (p<0.01). A blending ratio of 180.00 g of glutinous green rice and 400.00 g of rice nuruk had the highest preference among all the sensory items. Based on these results, we developed a green rice fermented beverage with unique flavor and physiological function activity of rice using glutinous green rice and rice nuruk, and the optimal blending ratio was determined to be 164.04 g of white rice, 195.96 g of glutinous green rice, and 414.61 g of rice nuruk.
