Purpose: The size of the salad consumption market has expanded since Covid-19, and continuous growth is predicted. Therefore, by extracting influential core purchasers in the salad consumption market and analyzing their purchasing behaviors and consumer types, this study intended to provide basic data for establishing a marketing strategy. Methods: The analysis data is the purchasing data of 576 people who have purchased salads between 2016 and 2020 (panel data of the Rural Development Administration), and in the social network analysis, the centrality structure was analyzed. Results: First, in the results of analyzing the causes of the rapid increase in salad consumption in 2020, it was found that the increase in consumption of new purchasers (n=102) had little effect. The existing consumer type (n = 474), which has been the majority of the salad consumption market so far, were consumers with stable income. However, the results of study indicated that the type of consumers has expanded since low-income class as well as high-income class increased consumption of purchasing salad. Second, in the results of analyzing the types of key purchasers with great influence in the salad consumption market, there was a difference from the results of frequency analysis in age, number of family members, existence/absence of children, and income decile. This suggests that there should be a difference between the type of customers according to the apparent quantitative figure and the actual influential purchasers. Third, in the results of analyzing the salad purchasing behaviors of core purchasers, the purchasing site for existing purchasers was large-scale marts and for new purchasers it was corporate-type supermarkets. Purchases were concentrated on Saturdays for both existing and new purchasers. As for the purchased products, existing purchasers had a high preference for products made of chicken, and new purchasers had a high preference for vegetable/fruit salad. In particular, in the results of purchased products by age group, in the case of 50s and 60s, it was an interesting result that there was a difference between the products purchased by the existing and new purchasers even though they were the same age. Conclusion: When establishing a marketing strategy in the salad consumption market, it is necessary to pay attention to the purchasing behavior of key buyers.

Objective: This study aimed to develop loop-mediated isothermal amplification (LAMP) combined with lateral flow dipstick (LFD) and compare it with LAMP-AGE, polymerase chain reaction (PCR), and standard Salmonella culture as reference methods for detecting Salmonella contamination in animal products and animal production environmental samples. Methods: The SalInvA01 primer, derived from the InvA gene and designed as a new probe for LFD detection, was used in developing this study. Adjusting for optimal conditions by temperature, time, and reagent concentration includes evaluating the specificity and limit of detection. The sampling of 120 animal product samples and 350 animal production environmental samples was determined by LAMP-LFD, comparing LAMP-AGE, PCR, and the culture method. Results: Salmonella was amplified using optimal conditions for the LAMP reaction and a DNA probe for LFD at 63℃ for 60 minutes. The specificity test revealed no cross-reactivity with other microorganisms. The limit of detection of LAMP-LFD in pure culture was 3×10² CFU/mL (6 CFU/reaction) and 9.01 pg/μL in genomic DNA. The limit of detection of the LAMP-LFD using artificially inoculated in minced chicken samples with 5 hours of pre-enrichment was 3.4×10⁴ CFU/mL (680 CFU/reaction). For 120 animal product samples, Salmonella was detected by the culture method, LAMP-LFD, LAMP-AGE, and PCR in 10/120 (8.3%). In three hundred fifty animal production environmental samples, Salmonella was detected in 91/350 (26%) by the culture method, equivalent to the detection rates of LAMP-LFD and LAMP-AGE, while PCR achieved 86/350 (24.6%). When comparing sensitivity, specificity, positive predictive value, and accuracy, LAMP-LFD showed the best results at 100%, 95.7%, 86.3%, and 96.6%, respectively. For Kappa index of LAMP-LFD, indicated nearly perfect agreement with culture method. Conclusion: The LAMP-LFD Salmonella detection, which used InvA gene, was highly specific, sensitive, and convenient for identifying Salmonella. Furthermore, this method could be used for Salmonella monitoring and primary screening in animal products and animal production environmental samples.

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.

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.
