The purpose of this study is to obtain the implications for establishing a marketing strategy for retailers by analyzing whether the consumer's preference for products (food) is influenced by on-line, off-line, and omni-channel preferences. The research model consisted of the effects of consumers' food selection characteristics on business preference and omni channel preference. The results of analysis based on 477 questionnaires are summarized as follows. First, food purchasing characteristics that utilize the seven characteristics of (1) freshness of food, (2) taste, (3) quality and safety, (4) tasting, (5) food function and information, (6) country of origin, and (7) brand loyalty, has various effects on types of business preference, omni-channel preference. The adopted hypotheses were selected in order of brand loyalty (5 times), freshness (3 times), tasting (3 times), and origin (1 time). The selective attributes on foods are: (1) what kind of brand, (2) how good the freshness is, (3) tasting. (4) The country of origin is to be compressed. Actually consumers seem to utilize only the core selective factors that are appropriate to the characteristics of the distribution channel rather than all of them in the shopping of the food, and there is three characteristics on Convenience Store and only one or two factors in the other types of business. Second, in the analysis of the omni-channel preference analysis, food selection characteristics has been shown to have a limited effect, which is attributed to the fact that the consumer has not yet understood the concept of omni channel. Third, the results of this study suggest that there is a need to reflect the selection characteristics of foods that have diverse influences by business type in the marketing strategies. Because consumers make reasonable consumption to use both on-line and off-line simultaneously, consumers who use Omni Channel focus on quality and safety of food, identify products through tasting, pursue brands that can trust anywhere. Customers who pursue rationality will have a high preference for using Omni Channel. Product choice characteristic has significant effect on omni-channel preference. For a few years, omni-channel strategy of retailers meets with a difficulty. This study make a first attempt to study omni-channel preference changing retailing paradigm.

The purpose of this study is to analyze service quality factors that consumers perceive during their purchasing product on Internet Shopping Mall. The study defines the characteristic quality dimensions of Internet Shopping Mall by adding three dimensions consisting of convenience, security and entertainment to PZB's SERVQUAL scale. Consumers' purchase process on Internet Shopping Mall is examined by finding the relation between their perceived risk factor and repurchase intention. The study results show that consumers' higher appraisal degree on service quality means their higher repurchase intentions, their lower perceived risks degree. The repurchase intentions and the perceived risks degree have negative correlation. The more consumers have experienced buying on Internet Shopping Mall, the higher consumer assess service quality, they have higher repurchase intention and lower perceived risk. The most basic contribution is that new service quality dimensions, which is able to clarify service quality on Cyber Mall, is identified with the established PZB(I988; 1991)'s SERVQUAL dimensions.

This research investigated experimentally on the population growth in the aquatic microcosm with the wastewater of plating factory. The purpose of this study was to evaluate the effect of culture conditions of the characteristic growth pattern of the examined species. Population of the system is consists of three organisms; Chlorella vulgaris as a producer, Cyclidium glaucoma as a consumer and Pseudomonas putida as a decomposer. The different growth patterns of each population are followed by surfactant type; Especially C. glaucoma was sensitive, Ch. uvlgaris was maintained population size stably even at high level of surfactant and p. putida was not significantly affected. After treatment of waste water from plating factory, it began to be affected at 1.0% solution treatment to Ch. vulgaris which the cell number was decreased prominently after 2 days, and C. glaucoma was disappeared at 2.5% solution treatment. P. putida was showed increasing pattern according to treatment concentration, at 2.5% solution and population size grew double. The result from current microcosm study indicates that this model system can be applied to environmental assessment method for various pollutants.

This study aims to investigate the characteristics of Chinese consumers, who are growing up as the global biggest consumption market, according to G sensibility types, and to provide the data base for China market by analyzing the consuming pattern per sensibility and the preferred color. For the investigation, the survey on G sensibility and consuming pattern was conducted for consumers in four cities of China. As a result of classification of G sensibility types, it was found that Chinese consumers tended to behave in accordance with their values and identities and the most general type in them was G1 pursuing the reasonable and logical consumption, unlike Korean consumers who tended to be shown as G3 for the most general type according to the preceding study. As to characteristic of consumption, Chinese consumers preferred to purchase clothes from the department store, and in case of G2 type, the characteristics was corresponded with Actionist's character which shows the wide range of behavior and high-consumption, by preferring the road-shop next to the department store. Chinese consumers tended to purchase the clothes on the basis of their preferred colors, and especially it was shown that achromatic color was very commonly preferred. Also the black color was on the highest preference, and white, dark gray and light gray were followed. Meanwhile, in chromatic color, it was found that brown, orange, red and blue were preferred in order, and in case of G4, it was found that they preferred more various colors compared to the other types. This result could be used as the data base for the marketing strategy of fashion design industry and the related companies, as well as the new communication method for the consumers.

The random utility theory and the multinomial logit model (including a more recent variant--the mixed multinomial logit) derived from it have constituted a back bone for theoretical and empirical analyses of various travel demand features including mode choice. In their empirical applications, however, it is customary to specify random utilities which are linear in modal attributes such as time and cost, and in socio-economic variables. The linearity helps easy derivation of important information such as value of travel time savings by calculating marginal rate of substitution between time and cost. In this paper the author focuses on the very linearity of the random utilities. Taking into account the fact that the mode chooser is also labour supplier, commodity consumer as well as leisure-seeker, the author sets up a maximization model of the traveller, which encompasses various economic activities of the traveller. The author derive from the model the indifference curve defined on the space of modal attributes, time and cost and investigate under what conditions the random utility of the traveller becomes linear. It turns out that there exist the conditions under which the random utility is really linear in modal attributes, but the property does not hold when the traveller has a corner solution on the space of modal attributes, or when the primary utility function of the traveller is directly affected by labour provided and/or the travel time itself. As a corollary of the analysis, a random utility is suggested, approximated up to the second order of the variables involved for empirical studies of the field.

In this study, wild sesame leaf aromas (WSLA) were extracted and the extracted aromas were entrapped in porous potato starch micelles. The entrapped aromas did not evaporate, even by heated water treatments, and remained until a physical treatment such as chewing. Thus, the entrapped WSLA starch was used to make precooked instant noodles in order to mask or/and reduce an unpleasant raw flour flavor. The efficiencies of the flavor entrapment were analyzed using gas-chromatography equipped with solid phase micro-extraction (SPME), as well as by sensory evaluation. The highest yield of the porous potato starch was shown as 82.4% at an inlet temperature (IT) of $170^{\circ}C$, an exhaust temperature (ET) of $90^{\circ}C$, and a feeding rate (FR) of 40 mL/min. In the porous starch made by IT at $200^{\circ}C$, ET at $100^{\circ}C$, and FR at 50 mL/min, the entrapment efficiency was 68% by GC analysis; this starch also had the highest WSLA and consumer acceptability, but the lowest raw flour flavor, according to the sensory evaluation results.

There are two kinds of commercially available ginseng root, red ginseng and white ginseng processed from fresh ginseng root Those ginsengs are primary product from fresh ginseng root and have the characteristic of keeping their original root shape Processed ginseng products are made from either red ginseng or white ginseng by way of complicated process of pulverization. Extraction. Condensation, fettering, sterilization, etc. Among them there are extracts. extract powder, powder, capsules tablets, Candy, drinks, nectar, jelly, gums. chicken soup. tonic. etc. to meet the demand for consumer's pretheronce . The 200 kinds of processed secondary products are approximately produced in the form of 20 kinds of ginseng products by about 60 domestic companies. In spite of about 213.000 million won of domestic market in 1993. it seems like that the ginseng market of the future has not a good prospects The total market sale of white ginseng in Korea has been continuously decreased since 1991 And 963 tons of white ginseng was consumed in domestic market in 1993 The domestic market sales of white ginseng in origina1 root shave. was 90, 000 million won in 1993 and market price of the fine root used as a source of processed products has not been changed in these ten years. The total market sale of red ginseng and its processed products was 58, 000 million won in 1993 9.800 mi11ion won of red ginseng in original root shape and 48.000mi11ion of processed red ginseng product. Ginseng products such as extracts, drinks, teas and tonics etc atre mostly exported to south-east Asia. And the total exports of ginseng pi.oducts (extracts, drinks teas) decreased to 54 million dollars in 1994, compared with 85 million dollars in 1992. Despite of extensive knowledge about ginseng little is still known about the development of new processed ginseng pl.oducts because of "Know-How". Some papars have presented the effects of extracting method(amounts of solvent. time. temperature, equipment. etc.) on the quality and yields of ginseng extr acts. Also. some researchers have carried out a few studies on the poriflcation of the extracts and the amounts of precipitation in the drink at variotas pH during the storage for preventinly drink from precipitation. A fell studies on the preservation of Korean ginseng powder. tea. Extract powder by irradiation and ozone treatment have been reported by some researcher for the improvement hygienic quality of ginseng products There are also some reports about the effects of ginseng components on the acid production by lactic acid bacteria or acetic acid bacteria. and alcohol production by yeast for the development of new ginseng products processed by fermentation. To make ginseng more able to contribute to the health of mankind in the future. consistent and considerable efforts should be focussed on improving the taste of ginseng and developing various new product as a health food or a function food.tion food.

This study investigated the effects of saltwort powder on the antioxidant activity and quality characteristics of patties added with saltwort powder. Patties were prepared with different amounts (0, 1, 2, and 3%) of saltwort powder. The total phenolic content, DPPH free radical scavenging activity, and pH of patties increased with increasing saltwort powder content (P<0.05). In particular, the moisture content and cooking loss of the group added with 2% saltwort powder were the highest and lowest, respectively (P<0.05). As the content of saltwort powder increased, $L^*$ and $a^*$ values decreased while $b^*$ value increased. Texture analysis showed that the hardness, chewiness, and gumminess of the control group were lower than those of the treated group (P<0.05). Consumer acceptability showed that 1% and 2% saltwort powder groups scored higher in terms of overall preference, appearance, color, taste, and texture compared to the other groups. Characteristic intensity rating of saltwort patties showed that as more saltwort powder was added, saltwort taste intensified; however, the increase did not affect juiciness, off flavor, or salty taste of the patties. Judging from the results, it was concluded that the addition of saltwort powder to patties in processing can enhance the preference, quality, and antioxidant activities of the patties, which elevates the value of patties.

This study was performed to examine the effects of electron beam irradiation on volatile flavor components of Shingo pear (Pyrus pyrifolia cv. Niitaka) and on their changes according to storing period following irradiation. Volatile flavor components in pear were extracted using simultaneous steam distillation and extraction (SDE) apparatus and analyzed by GC/MS. 46 components were identified in control whereas 45, 44, 48 and 51 components were identified in irradiated samples by electron beam at 0.25, 0.5, 1, and 3 kGy, respectively. Hexanal, n-hexanol, and (E)-2-hexenal were identified as the major volatile flavor components of all samples. The characteristic volatile flavor components of irradiated pear by electron beam were similar to those of control, and their effects depending on irradiation source were not different. In addition, there was no noticeable change in volatile flavor components of pear with storage at $4^{\circ}C$ for 30 days or with irradiation. Sensory evaluation indicated that the consumer receptiveness tended to be higher at a low level of radiation dose under 1 kGy than control, albeit not significant. Therefore, electron beam irradiation at low level of radiation dose under 1 kGy could be considered as an effective method to exterminate vermin and thus to improve the shelf-stability of pear without deterioration.

This study was conducted to investigate the antibacterial activities and sensory properties of a sauce containing tea extract and garlic vineger against raw fish. The sauce was evaluated antibacterial activity against Vibrio parahaemolyticus and Vibrio vulnificus which is considered as one of the major food borne pathogens. As a result, the sauce inhibited the growth of V. parahaemolyticus and V. vulnificus distinctly. In addition, the sauce with soy sauce and Kochujang showed the restricted growth of Vibrio parahaemolyticus and Vibrio vulnificus in sliced raw flatfish. Sensory evaluations were measured by 7-point hedonic scale using sliced raw flatfish with the sauce mixed with Kochujang and soy sauce. The score of texture in the sauce with Kochujang was significantly higher than that of regular Chokochujang (p<0.05). Moreover, total preference including appearance, texture, aroma and taste were significantly higher in the sauce with soy sauce than those of regular soy sauce (p<0.05). Consequently, the soy sauce with tea extract and garlic vinegar may enhance the satisfaction of consumer and antimicrobial activity that against V. parahaemolyticus and V. vulnificus, resulting in potential reduction the outbreaks of food borne pathogens.
