The purpose of this study was to investigate the levels of recognition, practice and information acquisition behaviors regarding food additives of university students for development of educational programs. The data were collected from 283 students in the Yeungnam region through a self-administered questionnaire. The level of concern about food additives was intermediate. The level of checking labels for food additives when buying processed foods was not high. The main reason for not checking labels for food additives was "Buying the special brand products repeatedly". In the factor analysis for perception of food additives, three factors were categorized; effect of food additives on human health, administration and regulation of food additives, and necessity of food additives. According to regression analyses, grade, concern about food additives and perception of amount of food additives had significant effects on human health. The significant variables for administration and regulation of food additives were gender, grade, major, monthly allowance and concern about food additives. In addition, major was a significant variable for the necessity of food additives. Many respondents did not reduce intake of food additives; males did less than females. Most respondents answered they did not acquire sufficient information about food additives. Regarding needs for information content on food additives, respondents wanted information about safety of food additives the most, followed by items of labels for food additives, and ways to reduce intake of food additives.

This study was carried out to find out the effect of food hygiene awareness on kitchen employees' performance in the banquet cuisine of five-star hotels in Seoul. 279 kitchen employees were asked to fill out the questionnaire, and the collected data were analyzed by SPSS package(version 11.0). First, results of analysis on food hygiene showed that there were four factors, each respectively named as, food security regulations, food storage, period of circulation of food, and food safekeeping. Second, after analyzing each item in whole according to each of the factors, the average degree of priority on food hygiene in general was 4.52. Results according to each of the elements showed that food security regulations(4.56) and period of circulation of food(4.55) were considered as a priority. After analyzing the difference between the degree of priority and degree of performance according to each of the factors, it was found out that the latter was significantly lower than the former in all factors. Third, after analyzing the difference of food hygiene priority in accordance with general characteristics, statistically significant difference was only shown in education(F=3.308, p<0.05) and class(F=4.418, p<0.01). Fourth, after analyzing the difference of food hygiene performance in accordance with general characteristics, the only significant difference was found in food security regulation of education(F=4.418, p<0.01) and food security regulation of class(F=3.859, p<0.01). Fifth, after analyzing the effect of cook's awareness of priority on food hygiene on the degree of performance, it was found out that the awareness of priority on food hygiene had a positive effect(+) on the degree of performance. Therefore, we can conclude that as kitchen employees recognize the priority on the food hygiene better, their degree of performance was higher.

Effect of quercetin on NO production and regulation mode of quercetin on oxidative stress, $NF{\kappa}B$ activation, and iNOS expression, possible mechanisms of NO suppression in LPS-stimulated macrophages were investigated. Treatment of RAW 264.7 cells with quercetin significantly reduced lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production dose-dependently ($IC_{50}$, $9.2\;{\mu}M$). Expression of iNOS and specific DNA binding activities of nuclear factor kB ($NF{\kappa}B$) were significantly suppressed by quercetin pretreatment. Quercetin reduced thiobarbituric acid-reactive substances (TBARS) accumulation, enhancing GSH level and antioxidant activities of enzymes, such as superoxide dismutase (SOD) and catalase. These results demonstrate quercetin may ameliorate inflammatory diseases by suppressing NO production through inhibition of iNOS expression, $NF{\kappa}B$ transactivation, and oxidative stress, which may be mediated partially by antioxidative effect of quercetin. Thus, quercetin appears to be used as a potential therapeutic agent for treating LPS-induced inflammatory processes.

This study determined the effects of television (TV) advertising restriction of Energy-Dense and Nutrient-Poor Foods on product and promotion activities by food companies producing or selling children's favorite foods. A survey using a selfadministered questionnaire was conducted via on-line or fax by marketers or R&D managers from 108 food companies. The data from 55 respondents (50.9%) were analyzed. Restriction exerted positive effects on food products with respect to compliance with labeling requirements (4.0 out of 5 points) and reinforcement of nutritional contents examination of new products (3.7 out of 5 points). Reformulations of products such as reduction of nutrients like sodium, sugar and fat were also reported. In addition, food companies underwent diverse changes in promotional activities, including modification of package designs and displays in stores, offering free gifts, discounts, etc. In conclusion, restriction of TV food advertising may contribute to improvement of children's food environment by encouraging food companies to make favorable product changes. On the other hand, the results also revealed that food companies adopt diverse marketing channels that are not yet under regulation. Hence, to make policies more effective, regulation needs to be extended from TV to other marketing channels to which children are easily exposed.

The effects of soy-isoflavones, which are phytoestrogens derived from plants with a flavonoid structure, on cyclooxygenase -2 (COX-2) expression, PGE2 production, and mapkinases expression, were investigated in experimentally-induced atherogenic rats by feeding a high fat-high cholesterol diet. Female Sprague-Dawley rats were bilaterally ovariectomized; sham-operated animals were used as controls. Three weeks later, the animals were randomized to the following treatments for an eight-week experimental period: 17$\beta$-estradiol (200$\mu$ g/kg diet), low concentration of isoflavones (0.8g/kg diet), and high concentration of isoflavones (4.0g/kg diet). In the group supplemented with a high dose of isoflavones, COX-2 expression was down-regulated. This down-regulation was accompanied by a reduced expression of pERK1/2. In the second experiment using 48-week old female Sprague-Dawly rats, the effects of isoflavones and estrogen were compared in the basal estrogen-supplementation at the level of 600$\mu$ g/kg diet. Isoflavones induced the marked down-regulation of COX-2 protein and the decrease in $PGE_2$ production in estrogen supplemented states and this was followed by the down-regulation of p38 among mapkinases. The two different mapkinases are involved in the down-regulation of COX-2 depending on estrogen-deficient and estrogen supplemented states. This kind of COX-2 down-regulation by isoflavones was not observed in the different tissue, mammary glands. Further investigations on the relationship between COX-2 and biological activities such as vasodilation by isoflavonesin the absence or the presence of estrogen ave required in vivo system of female rats.
