  • The flat-headed goby, Luciogobius guttatus, inhabits tidepools and river mouths, and stays under stones on the dried bottom for the duration of the low tide. To know the relationship of its respiration and habit in this fish, the epidermis of five appendages was observed. The epidermis has three layers: the outermost layer, middle layer and stratum germinativum. The outermost layer is composed of polygonal cells or rather flattened cells, and mucous cells. The unicellular mucous cells showing acid mucopolysaccharides are 11.1 to $16.1{\mu}m$ in mean height and in one or two rows. The middle layer consists mainly of large epidermal cells that are swollen by adjacent epidermal cells and arranged in a web-shaped structure. The swollen cells are 12.3 to $15.2{\mu}m$ in mean height and arranged in one to 11 layers. Since the swollen cells occupy the entire height of the epidermis, the epidermis is thick. A large number of blood capillaries are present just below the stratum germinativum. Taste buds are distributed at intervals on the surface of the epidermis. Based on these epidermal strucures, it is likely that L. guttatus utilizes cutaneous respiration in a dual respiratory systems.

  • The purpose of this study is to provide useful information for establishing efficient marketing direction by investigating the performance(satisfaction) and importance of the display of dining space for hotel banquets. The importance and satisfaction scores of the display of dining space were measured on the five-point Likert scale. The results were summarized as follows. 'Taste of food(4.53 point)', 'freshness of food materials(4.50 point)', and 'indoor cleanliness(4.38 point)' were considered highly important while 'carpet shape of the floor(3.68 point)' and 'art objects(3.69 point)' were scored low. As for the factors of satisfaction, 'freshness of food materials(3.86 point)', 'taste of food(3.85 point)', 'indoor cleanliness(3.74 point)', and 'overall cleanliness of tables(3.73 point)' were considered highly satisfactory while 'art objects(3.42 point)', 'item decoration(3.44 point)', 'furniture and accessory decoration(3.45 point)' were scored low. As a result of analyzing difference between importance and performance of the display of dining space, importance(4.02 point) was much higher than performance(3.60 point). For the IPA result, customers made much account of 'taste of food', 'freshness of food materials', 'indoor cleanliness', 'overall cleanliness of tables', 'cleanliness state of a banquet hall' and so on, so they were regarded as the items to be continuously cared for. Also, intensive care was needed in such factors as 'indoor temperature', 'food vessels', 'soundproofing' and 'colors of a banquet hall' due to low customer satisfaction.

  • Recently, the number of coffee shops has continued to increase, and information searches have been increasing for consumers who want to visit coffee shops. We wanted to find out the impact on the intention of revisiting a coffee shop by adding information search factors to the existing coffee shop's selection properties and search for the actual selection properties, and summarize the results as follows. The analysis of this study was conducted in two ways, before and after visiting a coffee shop through information search. First, the four factors and optional attributes that are important in information retrieval were the reliability of information (the number of reviews and views by coffee shops, recent postings), physical environment (the proximity of stores, the atmosphere, size, presence of side menus), visuality of information (physical environment, background, design, easy composition), merchantability (the taste of coffee, convenience of parking). In addition, the selection properties for satisfaction after visiting coffee shops through information search were derived from five general characteristics of coffee shops, menu, information consistency, taste of coffee, and convenience of parking, and among them, the consistency of information, taste of coffee, and general characteristics of coffee were found to affect the intention of revisiting again.

  • This study aimed to investigate recognition and satisfaction toward Korean herbal foods according to dietary lifestyle as well as the actual status of using ingredients for Korean herbal foods while looking for methods to improve use. The general characteristics of the respondents included relations with foods such as learning or working on them, and the correlations with the examined items were analyzed by grouping according to dietary lifestyle. Five significant dietary lifestyle groups were derived by analyzing the groups using the factor scores from the analysis. Recognition of Korean herbal foods was higher with older respondents and more cooking experience. Regarding experience related to Korean herbal foods, the housewives showed higher satisfaction when the ingredients of foods were bought and cooked. And satisfaction with price differed significantly by dietary lifestyle. With regard to experience of using ready-to-cook or ready-to-eat products, the groups with more cooking experience indicated relatively lower satisfaction with the taste of such products. When visiting restaurants, the groups with less cooking experience showed higher satisfaction with taste and nutritional values. Regarding the actual status of using ingredients for Korean herbal foods, most of the respondents answered that hygiene and quality management, distribution and marketing, and the promotion of ingredients are all essential.

  • A taste-testing method that accurately measures consumer-acceptance is critical during the course of the product development stage. Although various types of consumer-acceptance tests are available, the testing protocol appropriate for measuring the acceptance of ready-to-eat-meals (REM) has not yet been verified. In this study, various hedonic taste-testing methods (9-point hedonic scaling, best-worst scaling, open ended response) were compared for their efficiency and power in identifying the preferred REM menu of consumers. Forty-four consumers evaluated the acceptance of five types of REM menu samples consisting of a wide variety of flavors. Consumers initially used the 9-point hedonic rating method to choose the best and the worst sample among the 5 meals tested. Finally, consumers were asked to fill out open-ended comments where they could freely describe their liking and disliking of each sample. The results showed that the REM menu acceptance measured by the 9-point hedonic method that rated best-worst scaling exhibited a similar preference pattern. The open-ended response method could not provide a quantifiable acceptance data but was able to provide supplementary information regarding the limitations of the samples and therefore, provide a general idea of the direction of improvement during the product development.

  • Lactic acid bacteria (LAB) fermented food was prepared from milk or egg white powder (EWP) and added with five kinds of freeze drying protectant (FDP). Effects of FDP on growth and acid production of LAB were investigated. Effects of FDP on organoleptic properties of LAB fermented food were also studied. (1) Some of FDPs showed protective effect against damage to Lactobacillus acidophilus in LAB fermented food during freeze drying, while FDP did not show any protective effect against damage to L. acidophilus during freezing. This protective effect differed with substrate and concentration of FDP (2) Optimum concentration of Tween 80 and ascorbate added to milk sample was 0.2 % (W/V) and 1 %(W/V), respectively. Optimum concentration of raffinose and ascorbate added to EWP sample was 3 %(W/V) and 1 %(W/V), respectively (3) Among FDPs added to L. casei fermented food, raffinose and ascorbate added to EWP sample showed FDP effect. Among FDPs added to L. delbrueckii fermented food, raffinose added to EWP sample showed FDP effect. (4) Samples added with MSG showed MSG taste. Milk sample added with ascorbate showed slightly more acid taste than reference sample, while taste of EWP sample added with ascobate did not differ with reference sample. Tween 80 added to milk sample or EWP sample improved texture of LAB fermented food.

  • Fermentation characteristics of rice-grape wine with different mixing ratios of rice and grape, rice one vs. grape five (Exp.1), rice two vs. grape five (Exp.2), rice five vs. grape five (Exp.3), and rice five and grape two (Exp.4), were investigated. Final alcohol contents of Exp.4, Exp.3, Exp.2, and Exp.1 were 18.4, 16.0, 14.9, and 12.9%, respectively. Final alcohol content increased with increasing amount of rice. Acidity of four experiments ranged pH 3.4-3.92, and total acidity was 0.52-0.74%. Exp.4, Exp.3, Exp.2, and Exp.1 gave a values of 8.76, 12.77, 12.88, and 23.96, respectively. When different mixing methods were applied to Exp.1, the resulting final alcohol contents of Exp.6 (grape musts periodically added after rice fermentation), Exp.7 (rice and grape simultaneously added and fermented), and Exp.8 (rice added after grape must fermentation) were 2.3-3.2% Bower than that of Exp.1 (grape must added after rice fermentation), and total acidity was 0.72-0.74%. Sensory evaluation comparing conventional red wine and rice-grape wine of Exp.1 showed rice-grape wine was preferred in taste.
