Objective : Recently the number of health functional food (HFF) made with Traditional Korean Medicine (TKM) herbs have been increasing. However, there was a lack of the functional and safety information on HFF. Thus, this study was performed to investigate perceptions and consumptions of the HFF in Daegu area. Method : We used the data of 'Survey in Daegu' in 2010 and analyzed characteristics of perceptions and intake conditions of HFF of 1,208 participated inhabitants. Result : Among the 1,208 respondents, 30.4% were male and 63.5% were female. Most respondents (69.3%) were between 30's and 50's decade. The recognition rate of HFF made with TKM herb appeared to 86.2%. The major route of acquiring HFF information was 'mass-media' (49.8%) ; the primary reason of using HFF was 'For health promotion and anti-aging' (69.2%). On the other hand, the recognition rate of adverse effects was 53.3%. As for intake effect, 41.5% were satisfied at HFF consumption, while 56.0% did not feel special effects through the HFF consumption. In regards to purchase place, 'HFF store' was most selected by 38.0%. 69.1% of respondents selected to TKM decoction, the reason is that it made according to TKM physician's diagnosis considered their health condition. Conclusion : HFF intake was purpose to health promotion, but HFF made with TKM was consumed without any information about that. In order that HFF be used properly to promote health, the scientific and reasonable information of HFF made with TKM herb is need for consumers.

Purpose - The purpose of this study was to investigate market power of soybeans exported by the United States to Korea. Particularly, this paper considered dichotomous characteristics of genetically modified (GM) soybeans and non-GM soybeans and conducted empirical analysis of these two segregated soybean markets to understand key tenets of market power in international soybean trade. Design/methodology - The difference in market power between GM and non-GM soybeans was analyzed using Residual Demand Elasticity (RDE) and Residual Supply Elasticity (RSE) models over the period of 2008~2018. RDE and RSE models under an imperfect competition condition were used to estimate market margins and determine whether GM and non-GM exporters or importers exercised market power in the destination market. Findings - Empirical results suggested that the U.S. had a market power on both GM and non-GM soybean exports. GM exports had greater market power than non-GM exports (14% vs. 9%). By contrast, Korea showed an inability to grab market margin or exert market power in soybean imports. Both export supply by the U.S. and import demand by Korea were found to be more responsive to price changes of GM soybeans than to prices changes of non-GM soybeans. This might be due to a self-interested, profit-seeking strategy by the exporter and many concerned consumers regarding potential adverse effects of GMOs in the importing country. Originality/value - This paper fills the literature gap by exploiting market power in both GM and non-GM markets with explicit consideration of price correlations between GM and non-GM soybeans in Korea. A number of existing studies have provided evidence for market power broadly embedded in international commodity trade. However, studies focusing on Korean markets are limited. No study has explored the country's soybean trade. Furthermore, the majority of prior studies have almost exclusively focused on the market power from a standpoint of exporting countries without discussing importers' market structure. This paper also sought to understand potentially distinguished patterns of market power between GM and non-GM markets.

Quality Function Deployment (QFD) is the most complete and comprehensive method for translating what customers need from a product. This study utilized QFD to develop sauces made from Gochujang and to determine how to fulfill international customers' requirements. A customer survey and expert opinion survey were conducted from May 13 to August 22, 2014 and targeted 220 consumers and 20 experts in the U.S. and China. Finally, a total of 208 (190 consumers and 18 experts) useable data were selected. The top three customer requirements for Gochujang sauces were identified as fresh flavor (4.40), making better flavor (3.99), and cooking availability (3.90). Thirty-three engineering characteristics were developed. The results from the calculation of relative importance of engineering characteristics identified that 'cooking availability', 'free sample and food testing', 'unique concept', and 'development of brand' were the highest. The relative importance of engineering characteristics, correlation, and technical difficulties are ranked, and this result could contribute to the development Korean sauces based on customer needs and engineering characteristics.

In Korea, with a dramatic growth of Super Supermarket (SSM) in the wake of opening up the retail market and diversifying distribution, the consumer's purchase behavior about food and consumer goods changed. In order to investigate this change, this study was carried out through collecting and analyzing questionnaires from 190 men and women consumers at ages between twenties and sixties, living in Ulsan and Pusan. The result suggested that in overall features, men were mainly affected by design factors such as packaging design, color, and product design, whereas women were mainly affected by cost factors such as price and configuration. As for product properties, it was suggested that women put importance on the price concerning ail products, but men didn't. In addition, it was identified that women were impressed by advertisements on TV, and men and women both often purchased the product after confirming its information among the displayed products. Considering these results, we concluded that for a product whose main target is men in particular, the product development should focus on design. Moreover, as the packaging design and display affect on both men and women as important factors, hereafter a complementary study on the effects of the packaging design and display of manufacturers related to the products in this study is to be proceeded with greater interest.

In order to study milk preference and intake pattern of adolescents, the questionnaire survey was conducted with 929 middle and high school students residing in Chungnam cities through October and November 2004. Of the subjects, 56.3% liked milk or liked very much. They preferred chocolate and fruit-tasted milk to plain milk. Reasons for liking milk were for health and its taste, while the reasons of disliking were unpleasant smell and stomach upset. However those who disliked milk did like milk products such as ice-cream, yogurt or cheese. Of the students 35.1% drank milk 2 times or more a day, while 11.8% drank milk less than 2-3 times a month. As a whole they drank milk 8.6$\pm$6.7 times a week, of which 4.3$\pm$3.1 times for plain milk. Daily intake amount was estimated as 308$\pm$315mL. Middle-school students and boys drank more milk than high-school students and girls, respectively. Among the students 64.3% used to drink 1 cup of milk at a time, and 58.3% drank only milk without other foods. It was shown that 51.8% took milk school-serviced and their milk intake frequencies were higher than those of who were not given school milk service. Also milk intake frequencies was higher in students whose mother were housewives than in students whose mother had jobs. Milk preference, intake frequency, and one portion size showed significant and positive correlations each other. In conclusion, milk intake level of the subjects was insufficient and unpleasant smell and stomach upset were the main reasons which decreased milk preference and consumption. Students with low milk preference should be guided with how to drink milk deliciously, how to choose milk type and its products. It is also effective to go into school milk service and to provide milk at home anytime. As students like much fruit-tasted and chocolate milk, the milk processing industries should take their nutritional and health benefits into considerations importantly.

This study was done in order to monitor the quality properties of the granule using Bokbunja (Rubus coreanus Miquel) extracts. In order to prepare the granule depending on operational parameters such as content of Bokbunja extract ($X_1$, 0.4~1.2 g), sugar content ($X_2$, 6~10 g) and citric acid content ($X_3$, 0.1~0.3 g), a response surface methodology was applied to monitor the optimum recipes on the organoleptic properties and Hunter's color. The optimum recipe on the organoleptic color showed extract content of 0.96 g, sugar content of 7.05 g and citric acid content of 0.232 g. The optimum recipe on the organoleptic flavor showed extract content of 0.86 g, sugar content of 6.04 g and citric acid content of 0.215 g. The optimum recipe on the organoleptic taste showed extract content of 0.92 g, sugar content of 6.39 g and citric acid content of 0.251 g. The optimum recipe on the overall palatability showed extract content of 0.86 g, sugar content of 6.65 g and citric acid content of 0.272 g. The response surface of the Hunter's color b value was similar to the response of the overall palatability; therefore, the optimum conditions accepted by the consumers were 0.8 g Bokbunja extract content and 0.6 g sugar content in the Hunter's color a value of 6.0.

In this study, the antioxidant activities of 27 medicinal herbs and plants were measured. The dried medicinal herbs and plants were pulverized and extracted by water, 15% ethanol, and 45% ethanol, respectively at above $80^{circ}C$ for 90 minutes. The original and diluted extracts were tested for their antioxidant activities by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging activity assay. Cornus officinalis (C) and Scutellaria baicalensis (S) were selected to develop rice wines with higher antioxidant activities, based on the result of the 45% ethanol extraction. The rice wine developed using sample showed the highest antioxidant activity as comparing to those of other commercial rice wines. The rice wine samples were analyzed for titratable acidity, pH, $^{\circ}Brix$, reducing sugar content, color (L, a, b), amino-acidity, and ultraviolet absorption. The preferences for color, aroma, and overall acceptability were determined using a 9-point hedonic scale by 150 consumers. The sweetness, sourness, fruitiness, color, and medicinal herb-taste levels of the developed rice wines were also evaluated, using a 9-point just-about-right scale. The mean overall acceptability score of c (5.54) was higher than that of sample S. Based on the results, the sourness and medicinal herb-taste levels of sample s should be modified to higher levels, and the fruitiness of sample S also needs to be adjusted. For a future study, the final compositions of the developed rice wines will be adjusted for product launching based on the preference test data acquired in this study.

Domestic distribution market is in a time of transition for the present. With consumers' diverse demands, the growth of department stores, shopping malls, specialized shops and so on has been taken place radically and the competition among them also has become severe. In order to promptly and positively cope with the radically changing trend of market and the generation of competing business entities, they are necessary to establish a discriminated indoor space plan. With such desires as the expansion of leisure activities based on the increase of personal income and the up-gradation, diversification and individualization of living standard based on economic growth, the dining-out space, one of people's life environments, need a variety of changes. In the past, the specialized restaurants of composite shopping malls and department stores were a mere mediating space of food sale between producers and consumers, but today they become a discriminated and creative indoor space which representing customers' lifestyle. The purpose of this study was to examine the characteristic of public space of specialized restaurants at composite shopping malls and department stores and then present a discriminated spatial marketing strategy in order to find out the direction of its proceeding in the future. Therefore, the purpose of this study was to work out basic data for the development of dining-out contents at the time of appearing diverse composite dining-out spaces in the future and of establishing a renovation plan of specialized restaurants at composite shopping malls and department stores in order to provide customers a space which could satisfy their desires. In this vein, the characteristic and composition of necessary space was analyzed based on the examination of cases. The investigator hopes that study findings are used as basic data for the study on the interrelationship between the sale space and dining-out space of composite commercial facilities and for the establishment of marketing strategy to attract customers.

Background: The nematode species belonging to genus Anisakis occur at their third larval stage in numerous marine teleost fish species worldwide and known to cause accidental human infection through the ingestion of raw or undercooked fish or squids. They may also draw the attention of consumers because of the visual impact of both alive and dead worms. Therefore, the information on their geographical distribution and clear species identification is important for epidemiological survey and further prevention of human infection. Results: For identification of anisakid nematodes species isolated from largehead hairtail (Trichiurus japonicus), polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of internal transcribed spacers of ribosomal DNA were conducted. Mitochondrial cytochrome c oxidase subunit 2 gene was also sequenced, and phylogenetic analysis was conducted. From the largehead hairtail (n = 9), 1259 nematodes were isolated in total. Most of the nematodes were found encapsulated throughout the viscera (56.2 %, 708/1259) or moving freely in the body cavity (41.5 %, 523/1259), and only 0.3 % (4/1259) was found in the muscles. By PCR-RFLP, three different nematode species were identified. Anisakis pegreffii was the most dominantly found (98.7 %, 1243/1259) from the largehead hairtail, occupying 98.7 % (699/708) of the nematodes in the mesenteries and 98.1 % (513/523) in the body cavity. Hybrid genotype (Anisakis simplex ${\times}$ A. pegreffii) occupied 0.5 %, and Hysterothylacium sp. occupied 0.2 % of the nematodes isolated in this study. Conclusions: The largehead hairtail may not significantly contribute accidental human infection of anisakid nematode third stage larvae because most of the nematodes were found from the viscera or body cavity, which are not consumed raw. But, a high prevalence of anisakid nematode larvae in the largehead hairtail is still in concern because they may raise food safety problems to consumers. Immediate evisceration or freezing of fish after catch will be necessary before consumption.
