This study investigated the epidemiology of Listeria (L.) monocytogenes, a food-borne pathogen. The epidemiology of food-borne pathogens is of great importance for clarifying bacterial origin and preventing bacterial contamination and infection. This work examined 68 L. monocytogenes strains, including 11 reference strains and 57 isolates from imported US beef, domestic meats (beef, pork, chicken meat), raw milk, and milk plants. The random amplified polymorphic DNA (RAPD) techniques were optimized to develop a standard molecular epidemiological analysis of L. monocytogenes. There was great genetic variability among the isolates, which produced 24 and 34 RAPD patterns with primer HLWL85 and HLWL74, respectively. The discriminatory power of the RAPD methods with HLWL85 and HLWL74 primer were very high (DI = 0.957; S ${\geq}$ 80%, S ${\geq}$ 95%). Some RAPD types were specific to origin. A few RAPD types were specific for L. monocytogenes strains belonging to a particular serotype. Using the HLWL85 primer, the strains isolated from milk plants could be distinguished from the other strains. And using the HLWL74 primer, the strains isolated from imported beef (US) could be distinguished completely from the other strains.

In Korea, for a long time Rhus verniciflua has traditionally been used as an herbal medicines plants. A stem of Rhus verniciflua has been used to treat gastrointestinal trouble with in form of boiled chicken as a folk medicine. But it has been recognized as an extremely active allergen causing skin reactions. The chief allergenic component, urushiol, is found within the oleoresinous sap of Rhus verniciflua. Most components of urushiol have unsaturated side chains. These unsaturated side chains of urushiol are important to polymerization of these natural products. The urushiol components in Korean lacquer were isolated by reversed phase HPLC. The molecular weight of purified urushiol was determined as 340 from mass analysis. This compound was identified as Heptadecatetraenyl catechol (MW 340).

This study was carried out in order to develop supplementary foods for infants using Korean foods. Thirty-four different kinds of supplementary foods were developed and fourteen representative ones were selected to be analyzed chemically. The results are as follows: 1. The developed supplementary foods were 34 kinds and divided into 3 stages. First stage is designed for the babies just beginning to eat pureed vegetables and fruits. Second stage combined the nutritional attributes of both vegetables and meat. Third stage featured tender, bite-size pieces of meats and vegetables that appealed to the most mature tastes of basies. 2. In the production of prepared foods; water, milk, vegetable juice, fruit juice, and soy milk were used as the liquid source; rice, rice starch, chestnut, noodle, potatoes, sweet potatoes, rice cakes as the carbohydrate source; fish, meats soybean curd, beans, eggs, chicken, cow liver as the protein source; and vegetables and fruits were used as vitamin & mineral source. 3. The approximate composition range of the products were 10.91∼24.46% carbohydrate, 0.15∼6.06% protein, 0.092∼7% fat, 0.13∼ 1.37% ash, 0.63∼36.34% calcium, 0.092∼0.48% iron and 0.42∼16.36% vitamin C.

The purpose of the present study was to find the preferences of college students and to understand trends in their consumption patterns. This survey was conducted using a questionnaire containing 50 questions answered by 614 sudients of 4 universities in Daejeon and Seoul and the following result were obtained . 1. The majority of students favored coffee, yulmy tea, ginseng tea, and lllack tea in decreasing order. Only 49.0% of the students believe that ginseng was beneficial to the human life as a health, fond . 2. 54% of the students had experience in taking fresh ginseng and 68% had used in white ginseng. 3. Their expectations for the efficacy of ginseng were as remedies for hang-over syndrom, high blood pressure, heart trouble, liver trouble, and gastronic trouble, in decreasing order. 4. Most of the students took soup made by adding ginseng to chicken broth (SamGyetang) when taken ginseng. 5. The percent of students who had taken coffee was 97.7%, whereas only 48.3% had used processed ginseng products. The female students especially disliked ginseng tea. 6. The preferences of the students indicate that the likelihood that they will be major consumers of ginseng in the future is very low.

In order to compare the pharmacokinetic profiles of enrofloxacin-HCL)ENFLX-HCL) and enrofloxacin-KOH (ENFLX-KOH) after oral administration in broiler chickens, the study was performed. The chickens used in this study weighed $1.82 {\pm}0.2 kg$ and clinically healthy. The dose of intravenous and lral administration was 5 mg per kg of body weight as enrofloxacin. After intravenous injection of enrofloxacin, it showed two-compartment model with the rapid distribution phase and the slow elimination phase. The mean apparent volume of distribution (Vd) was 2.70 l/kg. The mean half-life of elimination and distribution showed 8.26 h and 0.44 h, respectively. The mean area under curve (AUC) was calculated as $19.7 {\mu} g{\cdot} h/ml$. After oral administration of ENFLX-HCL and ENFLX-KOH with a rate of dose 5 mg of enrofloxacin/kg of body weight, Both of the products were showed one-compartment model unlike that of i.v. enrofloxacin standard solution showed the mean bioavailability of 79.64% for the ENFLX-KOG and 86.24% for the ENFLX-HCL. The mean total body clearance of the former was 0.24 l/kg/h and the latter 0.42 l/kg/h. Both enorfloxacin formulations seemed to have good tissue distribution and penetration as indicated by large volume of distribution : 2.72 l/kg for the -KOH and 4.44 l/kg for the -HCL. With the results obtained in this study, ENFLX-HCL could be used in place of its salt form in chickens.

In the course of studies to discover natural products with anti-angiogenic properties, two cyclic octapeptides, octaminomycins A (1) and B (2), were isolated from the cultures of Streptomyces sp. RK85-270. Octaminomycins suppressed the vascular endothelial growth factor (VEGF)-induced proliferation, adhesion, tube formation, migration, and invasion of HUVECs. Anti-angiogenic activity was futher confirmed in vivo by the chicken chorioallantoic membrane assay. We also identified that 1 and 2 inhibited the phosphorylation of VEGF receptor 2, AKT, and ERK1/2 and the expression and activities of MMP-2 and MMP-9. These results suggest that 1 and 2 may serve as potential scaffolds for the development of therapeutic agents to angiogenesis-dependent diseases.

The purpose of this study is to find out how SNS marketing activities affect brand recognition, brand familiarity, and purchase intention for consumers who have purchased products from franchise chicken stores, including whether there is a moderating effect according to gender. SNS marketing activities were set up by configuring three attributes which are, SNS advertising, SNS information, and SNS events as sub-factors. For empirical analysis, a survey was conducted on SNS users, and SPSS/AMOS statistical programs were employed for the data analysis. First, the result of the empirical analysis showed that SNS advertising, SNS information, and SNS events have a significant positive effect on brand recognition. Second, it was found that the SNS events had a significant positive effect on brand familiarity. Third, it was found that SNS advertising has a significant positive effect on purchase intention. Fourth, it was observed that brand recognition has a significant positive effect on brand familiarity. Fifth, it was found that brand recognition and brand familiarity have a significant positive effect on purchase intention. Sixth, it was found that gender plays a significant role in the relationship between these constructs. Therefore, it can be assumed that the hypothesis presented in this study is sufficiently proven.

The selenium content of a wide variety of Korean food was determined by neutron activation analysis. Most fruits and vegetables contained quantities of selenium less than $0.4{\mu}g/g$. Grain products varied widely in their selenium content with $0.5{\mu}g/g$ and barley cereal as high as $0.7{\mu}g/g$. Dried milk powder sample ranged from $0.7\;to\;0.15{\mu}g/g$. Chicken muscle contained about $0.7{\mu}g/g$. The content of sea food was generally higher, ranging from $0.3\;to\;3.65{\mu}g/g$. These values suggest that a diet well balanced in other nutrients is probably also nutritionally adequate with regard to selenium, although possible effects of cooking and biological availability remain to be investigated.
