A survey was carried out from 143 cooks working at the deluxe hotels in Seoul to obtain the information on the working environment, characteristics, and the satisfaction of the cooks to improve the culinary art training program and the working environment. The results were as follows: Most of the cooks(58.7%) worked for 8-9 hours/day and 51.7% of the cooks earned 1-1.5 million won in a month. The cooks had average 1.6 licenses per person, however, their licenses accorded with their work place only with 85.3%. Subjects were unsatisfied with the pay(55.2%), but 42.7% of the cooks hoped to work in their current work place. If they could transfer to other work place, they wished to run a restaurant of their own. The unsatisfaction rate was high among the cooks worked for 10-15 years, and 19.2% of them was unsatisfied with the environment of work place and 11.5% was in promotion. The longer the working period of the cook, the higher the recognition of the culinary skill. Also, the more frequently transfer to other places, the higher the self-estimation in their skills. Subjects answered that the most important factors for good cooking are the good taste and hygiene. The quality of ingredients was recognized more important among the cooks worked for longer period. The greatest hindrance for the improvement of cooking skill was indicated as insufficient knowledge among the cooks worked under one year, lack of confidence among those worked for 2-5 years, and authoritarianism of seniors for 6-15 years. They answered that the most important qualification for cook is the sincere attitude. The cooks with under 5 years of experience indicated experience and studying attitude and the ones with over 6 years of experience culinary skill as the important factors for cooks. The important factors for promotion was pointed out as culinary skill and human relationship.

This study used K-mean cluster analysis to evaluate the preference and satisfaction according to consumption behavior of naturally fermented bread products among customers residing in the Seoul area. Naturally fermented bread products were best recognized as "great nutrients for good health" ($3.91{\pm}0.87$). The preference for naturally fermented bread products was due to "good taste and flavor" ($3.39{\pm}0.95$), and customers with "intention to purchase" showed a mean of $3.21{\pm}0.94$. The overall satisfaction for naturally fermented bread products was $3.26{\pm}0.75$. Among the specific categories that contributed to this overall satisfaction, "quality" showed the highest satisfaction with $3.43{\pm}0.77$, whereas "price" ($2.77{\pm}0.76$) and "variety" ($2.77{\pm}0.75$) exhibited the lowest. Among the items to modify for naturally fermented bread products, "variety" was the most important item (21.8%), followed by "lower price" and "convenience of purchase" at 19.7% and 17.9%, respectively. In K-mean cluster analysis, customers who frequently visited the bakery and purchased naturally fermented bread products (cluster 1) expressed strong preference, satisfaction, and consumption behavior. Furthermore, these customers expressed high satisfaction in "quality", "convenience of purchase", and "variety" of naturally fermented bread products.

Objectives: This study was conducted to identify factors that influence the consumption of temple food and to find systematic methods improving the popularization of temple food. Methods: A self-administered questionnaire was applied to 304 temple food restaurant visitors, including 232 local and 72 foreign individuals. The questionnaire was designed to investigate recognition, consumption, preference and popularization of temple food among restaurant visitors. Results: The study population consisted of 30.6% men, 69.4% women. 76.3% were Korean while 23.7% were foreigners. The responses on their impression on temple food contained the words, "vegetarian" (4.64), "plain and familiar" (4.19), and "good for dieting" (4.16). The most commont reason to favor temple food was its "mild taste" (63.0%) in the local group while foreigners preferred it because it is "good for health" (35.8%). The preferred kind of side dish of the local group was roasted dish (4.40), stir-fried dish (4.39), blanched vegetables (4.36), and food boiled with sauce (4.23); foreigner's high preference was for stir-fried (4.67), Jangachi (4.63), food boiled with sauce (4.56), and Buggak (4.55).. Most respondents thought that it is necessary to maintain the traditional form of temple food. While 43.5 percent of Koreans responded that "the five pungent vegetables" could be allowed, 62.8 percent of foreign respondents said it is permissible. Conclusions: A systematic approach to improve the temple food that reflects both foreign and local preference while maintaining its originality is necessary for its globalization. Furthermore, restaurants specialized in temple food should be expanded and promoted through effective marketing strategies that would make the cuisine easily accessible and spread throughout the world.

Musty and earth odors caused by geosmin and 2-MIB are the major complaints from the drinking water consumers. Therefore, early detection of geosmin and 2-MIB is the key to prevent off-flavor occurrence. In this study, a rapid method using stir bar sorptive extraction (SBSE) in combination with the GC/MS was investigated to analyze geosmin and 2-MIB in water. The SBSE method, a solventless extraction technique, was optimized and then applied to the analysis of geosmin and 2-MIB in water. The SBSE technique was found to be a simple and fast procedure that allows many samples to be extracted simultaneously using very small volume (10~20 mL). In addition, the SBSE method offered high recovery and good linear regression coefficient for the geosmin and 2-MIB. The good repeatability of this method can be deduced from the low RSD (7.2~7.6%) at 10 ng/L for geosmin and 2-MIB. The limit of detection was determined 1~2 ng/L and the limit of quantitation was 3~6 ng/L. Above all, the SBSE method proved to be a very practical technique for the analysis of geosmin and 2-MIB in water.

This paper is intended to find out how much the university students in the Kyung-book area recognize Korean traditional foods and what their attitudes toward the seasonal manners and customs are, and to analyze the differences according to their life styles. The average recognition of 27 kinds of Korean traditional foods is found to be 2.17 in general, 2.00 with male students and 2.34 with female students, which figures are thought to be low. The recognition of female students is significantly higher than that of male students. 94.4% of the subjects for this study wish traditional foods to be handed down. The reasons for handing them don are Korean unique culture, which is the highest (78.4%), good nutrition(7.2%) and good taste(14.5%). No student points to low price as a reason, which shows that university students think traditional foods more expensive than western foods. There is a positive correlation(p＜0.05) between the evaluations and uses of traditional foods, so those with high evaluations of them use them more. The recognition of traditional foods is positively correlated to the attitudes toward the seasonal manners and customs, monthly family income(p＜0.01) and mothers' educational levels(p＜0.05). Based on life styles, the individuality-centered type shows the highest recognition of traditional foods(2.39), while the leisure-valuing type shows the lowest(2.03). There is a significant difference between the two.

This study investigated the physicochemical, microbiological, antioxidant, and sensory characteristics of Makgeolli supplemented with 10, 20, and 30% Codium fragile (Cf) during an 8-day fermentation period. The pH and acidity on day 0 were lower in Makgeolli supplemented with Cf (pH 3.55-3.65, acidity 0.26-0.29%) than in the unsupplemented Makgeolli (control) (pH 3.72, acidity 0.23%). The pH and acidity of Cf Makgeolli on day 8 were 3.08-3.12 and 0.67-0.75%, respectively. The sugar content increased steadily until day 4 (8.1-8.5 Brix) and then decreased steadily (6.5-6.8 Brix). The alcohol content increased steadily until day 8 (13.2-14.3%). The pH decreased, acidity increased, and alcohol content increased significantly (all P<0.05), with stepwise increases in fermentation time and Cf concentrations. The lactic acid bacteria counts were 9.28-9.37 log versus 8.18 log in the control. The DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] radical scavenging activities were higher in Cf Makgeolli (DPPH 74.63-84.64%, ABTS 51.01-64.79%) than in the control (DPPH 30.97%, ABTS 21.21%). Makgeolli supplemented with 10 and 20% Cf had the highest taste, smell, and overall acceptance scores. This study suggests that Makgeolli supplemented with 10 and 20% Cf could be developed due to its good physicochemical and microbiological characteristics, including high antioxidant properties and good consumer acceptance.

The elderly population in Korea is growing rapidly and their nutritional status is not acceptable. Data were collected from the self-administered questionnaire of 495 free living elderly, over 65years old, in Korea to asses the intake and consumption pattern of milk and dairy products. The questionnaire contains demographics, health related characteristics, and perception on milk, and consumption behaviors of milk and dairy products. Most of the elderly subjects understood that milk is good foods in terms of nutritive value and health. And 67% of the subjects satisfied with the sanitation status of milk on the markets. The kind of milk that majority of the subjects consumed was whole milk, and only 5.1% of them consumed low fat milk. Less than 20% of the subjects consumed milk everyday, living alone group consumed milk less frequently than living with others. It was found that the majority of the elderly subjects did not meet current recommendation for milk. Liquid and curd type yogurt were the major dairy products used among elderly, and the reasons were good taste and digestion. They believed that these kinds of dairy products help constipation and digestion problems. The price of milk was ranked for the first factor needed to be considered for milk and dairy products consumption in elderly korean.

Options available for utilization of animal wastes include sources of plant nutrients, feed ingredients for farm animals, substrate for methane generation, and substrate for microbial and insect protein synthesis. The wastes have the most economic value for use as animal feed. Performance of animals fed diets containing animal wastes is similar to that of animals fed conventional diets. Processing of animal wastes to be used as animal feed is necessary for destruction of pathogens, improvement of handling and storage characteristics, and maintenance or enhancement of palatability. Feeding of animal waste has not adversely affected the quality and taste of animal products. In the USA copper toxicity has been reported in sheep fed high-copper poultry litter, but this is not a serious problem with cattle. Potential pathogenic microorganisms in animal wastes are destroyed by processing such as heat treatment, ensiling and deep stacking. Incidents of botulism, caused by Clostridium botulinum, have been reported in cattle in some countries, and this problem was caused by the presence of poultry carcasses in litter. This problem has not occurred in the USA. With appropriate withdrawal, heavy metal, pesticide or medicinal drug accumulation in edible tissues of animals fed animal wastes is not a problem. Feeding of animal wastes is regulated by individual states in the USA. The practice is regulated in Canada, also. With good management, animal wastes can be used safely as animal feed.
