This study was designed to develop the strategy plans for the customer satisfaction on foodservice in the senior care facilities. For this, we examined the level of the customer satisfaction and foodservice quality. Additionally, the association between service quality, customer satisfaction, and social, psychological, physical factors of the aged were tested. Data from convenience samples from 3 senior care facilities were collected by using a questionnaire. Exploratory factor analyses were completed on 20 attributes for the food and service quality and 7 items for the social and psychological states of the aged, respectively. Cronbach's a was estimated for reliability, and Pearson correlation and multiple regression analysis were used for statistical analyses. The level of the satisfaction on foodservice was 4.01 of 5.0. The satisfaction on foodservice did not show the significant differences by gender, education level, BMI, and socio-psychological satisfaction. But the foodservice quality and the satisfaction showed significant difference by income and physical problem, and the goal of life of the eldely, respectively. Multiple regression analyses revealed that the determinants of the customer satisfaction on foodservice were the core quality of product, confidence, professionalism of employees and secondary quality of products. Especially, the kindness of employee is the most important attribute of the foodservice. Based on these results, we can set the strategy plans as follow: (1) the introduction of the foodservice evaluation system (2) the deployment of the event activities for offering fun to the customer (3) the continuous training of employees for ensuring the professional and kind service system, and (4) the introduction of selective menu system and take-out service of menu.

For the economical use of the medicinal effects and functionality of Chrysanthemum indicum L (gamkug) this study analyzed the physicochemical and sensory characteristics of juak (tradition Korean rice cakes such as backed rice cakes) prepared with different levels of Chrysanthemum indicum L. powder (0, 1, 2, 3, 4, 5%). The diameter of the juak increased with increasing levels of the added gamkug powder, whereas the height decreased with increasing amount of the powder. The Hunter colorimeteric L-values of the dough and gamkug-juak decreased as the amount of gamkug powder increased. Hunter a and b-values both increased with increasing levels of the gamkug powder. Textural characteristics results for the gamkug juak dough indicated increasing hardness and, chewiness values as the amount of gamkug powder increased. After cooking, there were decrease in hardness and chewiness as the amount of gamkug powder increased. Springiness, cohesiveness, brittleness were not significantly different as the level of gamkug powder increased. According to sensory evaluation results, appearance, color, and flavor showed significantlyn (p<0.001) higher scores as the addition level of gamkug powder increased. The 2~4% addition of gamkug powder presented significantly (p<0.001) higher scores for non-oily and herb taste. There were no significant differences in the sensory texture results among all treatments of the juak. After taste was deemed best for the containing 3% gamkug powder. Overall, the optimum addition level of gamkug powder was proposed as 3% in glutinous flour for attributes of appearance, taste, flavor, texture, and the overall acceptability of the product.

In this paper we propose a fast negotiation agent system that guarantees the reciprocity of the attendants in a bilateral negotiation on the e-commerce. The proposednegotiation agent system exploits the incremental learning method based on an artificial neural network in generating a counter-offer and is trained by the previous offer that has been rejected by the other party. During a negotiation, the software agents on behalf of a buyer and a seller negotiate each other by considering the multi-attributes of a product. The experimental results show that the proposed negotiation system achieves better agreements than other negotiation agent systems that are operated under the realistic and practical environment. Furthermore, the proposed system carries out negotiations about twenty times faster than the previous negotiation systems on the average.

This study was designed to develop a microencapsulated, water-soluble isoflavone for application into milk and to examine the hypocholesterolemic effect of such a milk product in a rat diet. The coating material was medium-chain triglyceride (MCT) and the core material was watersoluble isoflavone. The microencapsulation efficiency was 70.2% when the ratio (w/w) of coating material to core material was 15:1. The isoflavone release from the microcapsules was 8% after 3-day storage at $4^{\circ}C$. In in vitro study, 4.0-9.3% of water-soluble isoflavone in simulated gastric fluid was released in the pH range of 2 to 5 after 60 min incubation; however, in simulated intestinal fluid at pH 8, 87.6% of isoflavone was released from the capsules after 40 min incubation time. In sensory analysis, the scores of bitterness, astringency, and off-taste in the encapsulated isoflavone-added milk were slightly, but not significantly, different from those in uncapsulated, isoflavone-added milk. In blood analysis, total cholesterol was significantly decreased in the isoflavone-added group compared with that in the control after 6-week feeding. Therefore, this study confirmed the acceptability of MCT as a coating material in the microencapsulation of water-soluble isoflavone for application into milk, although a slight adverse effect was found in terms of sensory attributes. In addition, blood total cholesterol was lowered in rats which had been fed a cholesterol-reduced and microencapsulated, isoflavoneadded milk for 6 weeks.

Recently, 'Emotion' has attracted public attention socially and continuously in the fields such as construction, environment, design and products. Also, phenomenological concept of space through the physique in the viewpoint of the human-oriented aspect, namely, body, has been managed as a planned measure suitable for a new era and space. In this study, the author examined and analyzed the verbs and emotional vocabulary about the human body's behavior. The phenomenological space conception through body, i.e, flesh in this human centered point of view is being treated as the suitable planning measure on the new era and space. Though the epochal issue for Emotion is being attempted in many ways in various field such as product and marketing, the approach through the relationship between human and space. Therefore, we would like to see how the Emotion related to the movement that occurs in the space by analyzing the human body movement which is the subject of experiencing the space experimentally and research the characteristic of Emotion and space movement. SPSS 12.0 was used for the analysis to perform the analysis of basic statistics and Factor Analysis, and then to analyze the characteristic and emotional attribute for the experimental analysis. Comparing the activity for the 2 groups' behavior through the analyzed result with the test, active behavior was found to be higher than inactive behavior in the emotional value, and their bodies' motion showed averagely positive value in the emotional aspect; their bodies' motion was presented differently according to the attributes and amount of the people who would experience a specific space. However, the author found that affirmative and active behavior showed emotional aspect more than inactive behavior.

Fish paste containing Styela clava (Korean name: miduduk) was prepared for the supplementary value of the product, and it was evaluated for the color, textural properities, and sensory attributes. Increasing the amount of S. clava in the fish paste tended to increase the lightness (L), the redness (a), and the yellowness (b) in Hunter color values. All test samples with 3 mm thickness had good flexibility and did not break even after 4 times folds. Fish paste containing 20% S. clava showed the highest values in strength, hardness, and adhesiveness. In overall acceptance of sensory evaluation, fish paste containing 5% S. clava did not show any difference in comparison with non added control. These results suggest that S. clava can be applied to fish paste products to improve the quality and functionality.

The objective of this study was to evaluate physicochemical and sensory properties, the texture profile, and antioxidant activity of ginseng extract-supplemented quark cheese as a new cheese product intended to improve public health. After addition of less than 1.0% ginseng extract, the moisture content of quark significantly decreased, while fat and protein levels increased, although microbial counts and lactose and ash contents were not affected significantly (p<0.05). In terms of color, $L^*$ values decreased significantly with increasing concentration of ginseng extract, while $a^*$ values increased significantly (p<0.05). The results of texture profiling showed that cohesiveness and springiness were unaffected, whereas hardness, gumminess, and chewiness increased significantly. The 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical-scavenging activities of the cheese fortified with 0%, 0.5%, or 1.0% of the ginseng extract were $4.22%{\pm}0.12%$, $20.14%{\pm}1.34%$, and $56.32%{\pm}1.54%$, respectively. The results of sensory analysis indicated that bitterness, ginseng odor, and aftertaste significantly improved with increasing concentration of ginseng extract (p<0.05). However, there was no significant difference in the overall quality attributes of quark cheese between the no-supplement control and samples with less than 0.5% of the ginseng extract (p>0.05), suggesting that these products could help to promote public health as functional foods.

The in-vitro meat is a novel concept in food biotechnology comprising field of tissue engineering and cellular agriculture. It involves production of edible biomass by in-vitro culture of stem cells harvested from the muscle of live animals by self-organizing or scaffolding methodology. It is considered as efficient, environmental friendly, better ensuring public safety and nutritional security, as well as ethical way of producing meat. Source of stem cells, media ingredients, supply of large size bioreactors, skilled manpower, sanitary requirements, production of products with similar sensory and textural attributes as of conventional meat, consumer acceptance, and proper set up of regulatory framework are challenges faced in commercialization and consumer acceptance of in-vitro meat. To realize any perceivable change in various socio-economic and environmental spheres, the technology should be commercialized and should be cost-effective as conventional meat and widely accepted among consumers. The new challenges of increasing demand of meat with the increasing population could be fulfill by the establishment of in-vitro meat production at large scale and its popularization. The adoption of in-vitro meat production at an industrial scale will lead to self-sufficiency in the developed world.

Objective: The aim of this work was the characterization of the qualitative aspects of meat obtained from Teramana goats, an Italian indigenous breed of the Abruzzo region. Specifically, the study included a comparison with meat samples deriving from Saanen goat kids reared in the same environment and applying the same feeding protocol. Methods: Upon reaching about 7 months of age the animals were slaughtered and samples of muscle tissue were collected to be analyzed. Specifically, meat samples were subjected to evaluations of the physical parameters, including color and the meat ability to retain water, in addition to chemical evaluations that were focused to the determination of the total lipids amount, fatty acids composition, lipid oxidation, and volatile profile. Results: The meat samples obtained from the indigenous breed showed a less intense reddish color and no significant variations for the muscle tissue tendency to retain water, both regarding fresh and cooked meat. Several differences were instead observed in the fatty acid profile. The Teramana samples were richer in saturated fatty acids (p<0.01) and interestingly showed higher concentrations of rumenic acid (p<0.05), a conjugate of linoleic acid that has been associated with important health benefits for the consumers. Another important finding for these meat samples was the marked resistance to oxidative events, as evidenced by the thiobarbituric acid reactive substances-test (p<0.05) and by the characterization of the volatile profile that highlighted a strong reduction in the relative percentage of hexanal (p<0.05), commonly associated to lipid oxidation and the development of unpleasant aromatic notes. Conclusion: The collected data, therefore appeared useful for the valorization of the food product derived from the Teramana goat, although no sensory information has been collected to define the degree of acceptability by the consumers.
