The aim of this study has been two fold - to analyze the degree of utilization of Korean menu items in family restaurants; and to evaluate consumer satisfaction with the quality of family restaurant food and food-related service. A self-completed questionnaire survey of 280 consumers having meals in 6 family restaurants in Korea was undertaken and detailed information was collected from each. Consumer satisfaction with the quality of food and food-related service in family restaurants was evaluated by consumer questionnaires. It was measured by assessing 24 variables. Statistical data analysis was using SAS package program for descriptive analysis, t-test and analysis of variance. Importance mean score of customers was 4.07 out of 5, with performance mean score of 3.19. The gap between importance and performance scores was 0.87. The Importance-Performance Analysis (IPA) technique was used for obtaining information of the degree of utilization of Korean menu items in family restaurants. By the results of the IPA technique, menu items with fair to poor performance and high importance to the customer were cooked meals, noodles, steamed and grilled dishes, Korean salads, kimchi, beverages, single-dish course, suggesting that customer seemed to be dissatisfied with the degree of utilization of Korean menu items in family restaurants.

This study was performed to investigate the effect of food and nutrition label education on the perception and utilization of nutrition labels on food packaging, and to suggest the importance and necessity of food and nutrition label education in the school curriculum. 811 junior-high school students participated in this study and completed self-administered questionnaires regarding general characteristics, and the perception and utilization of nutrition labels. Knowledge of nutrition labels was tested by 13 questions on the questionnaire. Data was analyzed (using SAS package program) based on the educational experience with nutrition labels. Significant differences in each variable were tested using the $X^2$-test and t-test. Students who had learned about the food and nutrition labeling system had more knowledge of nutrition labels and were more likely to check the nutrition label before purchasing food. In addition, students who had been educated about food and nutrition labels in the school curriculum had a significantly higher understanding and recognition of the nutrition label system. These results suggest that education concerning the food and nutrition label system increased the students' interest in nutrition labels and helped them choose healthy food. Therefore, it is necessary to include an education program about food and nutrition labels in the school curriculum to help students use label information and make healthy dietary choices.

The purposes of this research were to; (a) identify useful information source; (b) assess the usefulness of the Internet as an information source; and (c) assess the degree of Internet utilization for purchasing process in food service industry. The results were as follows; 1. 'personal experience and colleague recommendation' was perceived as the most useful information source, whereas the most frequently used source was 'Internet web site' for real purchasing practice. 2. the most frequently used purchasing activity through Internet was 'online ordering', followed by 'gathering product/component information', however e-marketplace or Internet bidding were less performed by Internet. 3. acquisition of real time information, rapidity, accuracy, and increasing effectiveness of purchasing process were reported the advantages of Internet utilization. 4. respondents somewhat or strongly agreed with the importance of Internet in terms of present and future purchasing management. The results of the research suggest that Internet should be able to improve purchasing process and enhance buyer-supplier relationship directly or indirectly, therefore food service industry should consider making attempt to new purchasing systems through Internet for strategic sourcing and effective procurement management.

Previous studies suggest that polyunsaturated fatty acids with long carbon chains such as eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA) have several health benefits. However metabolic consequences of these fatty acids themselves and their regulation of transcriptional activity involving glucose utilization are not well established. Thus, the purpose of this study was to investigate how EPA influx affects cellular lipid accumulation and gene expressions involving $de$ $novo$ lipogenesis in hepatocyte cultures. Compared to oleic acid treatment, EPA treatment showed remarkably decreased cellular TG conversion and accumulation, along with phospholipids at a lower extent. As expected, EPA increased mRNA expression involving fatty acid influx and lipid droplet formation, but did not affect mRNA expression involving glucose utilization. EPA increased transcriptional activity of PPAR-${\alpha}$ and glucose responsive transcription factor when transcription factor binding protein was activated. Taken together, these data suggest that EPA decreases lipid accumulation through increases of the ${\beta}$-oxidation pathway without interruption of glucose utilization.

The effect of dietary lipid factors (plant and animal oil, cholesterol and ${\beta}$-sitosterol) on the liver, serum, and egg yolk cholesterol levels of the laying hen was studied. Single Comb White Leghorn laying hens, at 28 weeks of age, were fed two basal diets containing 8.0% soybean oil or 8.0% fish oil, with or without supplemental cholesterol (1.0%), ${\beta}$-sitosterol (2.0%) or combinations of both. Restricting caloric intake resulted in significantly (p<.05) decreased egg production and the total amount of cholesterol excreted via the egg was significantly (p<.05) different among treatment groups. Cholesterol supplementation to the two basal diets resulted in a significant elevation of liver, serum and egg yolk cholesterol levels. The addition of ${\beta}$-sitosterol lowered the cholesterol levels in liver and serum, while increased in the egg yolk (SO + ST, FO + ST). The anticholesterogenic effect of dietary ${\beta}$-sitosterol was not clearly exhibited in this study.

This study was carried out to obtain the information concerning the perception and utilization patter of the housewives about the edible oil and fats. Data were obtained through questionnaires from 442 housewives in Chonbuk area. The eating frequency of food that used oil & fat was affected by age, residing area and educational level. family's preference score of food that used oil & fats was 3.34 point in the 5 point scale. 47% of the subjects answered that the intake rate of oil & fats had more from vegetable oils than animal sauces. Most of the subjects had negative response such as increased cholesterol and body weight for psychological state after the intake of food that used oil & fats. The main reason why some housewives did not use frequently oil & fats was inconvenience of tidying up. The kinds of the oil & fat used frequently were soybean oil, sesame oil, com oil and perilla oil. The nutrition knowledge score rotated to oil & fat was 7.62 point in the 10 point scale. The eating frequency of food that used oil & fats and its preference were positively correlated. These results indicate that the housewives haute a widespread tendency to pursue a health and convenience in the utilization of edible oil & fats.

This study was carried out to investigate food-nutrition labeling perception and utilization classified by age in Busan. The survey was conducted from March 26 to April 30, 2008 by questionnaires and data analyzed by SPSS program. The results are summarized as follows: reasons for purchase of the processed food was 'delicious' in elementary school children and middle & high school students, but was 'easy to eat and cook' in the adults groups (p<0.001). The criteria for choice of the processed foods was 'taste' in all of the subjects. Eighty seven point five percent of the over 60's do not know about food labeling and 70.1% of them did not check the food label. The first confirmed items for buying the processed foods was 'expiration date' in all of the subjects (71.1%). In elementary school children, middle & high school students, 20's & 30's group, the ratio of awareness of nutrition label was higher than the 40's & 50's and over 60's group. For reading of nutrition label, all of the subjects except elementary group replied 'often' (p<0.001). For the experience of education and publicity on food-nutrition labeling, 54.3% of the subjects replied 'often', and there was a significant difference by age. For the necessity of education and publicity on food-nutrition labeling, 49.5% of the subjects replied 'necessary'.
