  • This research was designed to compare the subjective evaluation of texture image and preference by structure and sensible characteristics of women's suits fabrics between on- and off-line. 78 subjects who majored in fashion design evaluated the sensibility image and preference of 15 various kinds of specimens on- and off-line. Factor analysis, t-test, Pearson correlation and regression were used for a statistical analysis by SPSS WIN 13.0. The results of this study were as follows: 1. Women's suits fabrics were classified according to five sensibility image factors: 'classic', 'sophisticated', 'natural', 'characteristic', and 'practical'. 2. The results of the t-test showed that there were no differences between the on- and off-line evaluation of sensibility images. 3. The analysis of correlation indicated that the 'classic'-'sophisticated' and 'natural'- 'practical' sensibility images show a significant correlation between the two kinds of evaluation. 4. The results of regression revealed that 'sophisticated', 'characteristic' and 'practical' sensibility images had an effect on the purchase preference of women's suits fabrics. 5. 'Sophisticated', 'characteristic' and 'classic' sensibility images had an effect on the tactile preference of women's suits fabrics. 6. The structural characteristics of fabrics: thickness, weave and weight had an effect on the 'classic' sensibility image. Thickness had an effect on the 'sophisticated' sensibility image and fabric count had an effect on the 'characteristic' sensibility image.

  • This study was carried out to compare the nutritional status with food preference of subjects in eight constitutional groups on the view point of constitutional medicine. The constitutions of 124 college women was classified by Kwon's theory. Food preference of the subjects was surveyed in accordance with the suggested foods for each constitution and the health status was investigated by Cornell Medical Index. The following determinations were also made to compare food preference score with the nutritional status : Hb, Hct, WBC, serum levels of albumin, protein, IgG, IgA, IsM, $C_3$, Triglyceride, cholesterol, and total lipids, and lipoprotein fraction ratio. The distribution of the constitution revealed that Jupito individuals accounts 51.6%, the most followed by ; Saturno, 21.8%: Hespero, 10.5%: Jupita, 8.1%: Hespera, 3.2%: Mercurio, 3.2%, no subject belonged to satura. There were no difference among constitutional groups in food preference score, health status and the values of most blood components. Only significant difference was that the percentage of mental complaints in Mercurio was lowest and serum IgG level in Jupito was the highest among groups. Correlation between values of blood component and food preference score shows variety of different trends. However, the results suggested that the better food consumption of the subjects was in accordance with the suggested foods for the constitution, the better the nutritional status of the subjects was.

  • The present study aims to evaluate transfer resistance factors in railway stations and draw new implications. The data used for the model estimation are RP (revealed preference) data and SP (stated preference) data. Two types of models were used for the analysis: integration model which combined line-haul stage, transfer stage and shuttle stage and separation model which assessed the three stages separately. The results revealed that while bulk freight shippers mainly focused on line-haul stage, they put emphasis on transfer stage as well. It's especially notable that transfer stage was considered more important than shuttle stage. Therefore, in future transportation policies concerning rail freight, it would be crucial not only to enhance the competitiveness of line-haul stage but also make improvements in transfer stage regarding railway stations.

  • Recently, there has been a great deal of public interest in health foods, such as turmeric (Curcuma longa L). In this study, the baking features of turmeric powder were evaluated by making pan bread. To accomplish this, the effects of added turmeric powder on the results of mixograph analysis as well as, the pH and, fermentation rate were measured. In addition, the features of the bread were examined by testing the stickiness of the dough and the TPA of the product using a texture analyzer. Finally, the consumer's preferences were investigated by evaluation of the color difference, crumbScan and sensory evaluation. The results revealed that as the level of turmeric powder increased, the pH decreased. which resulted in the gas possessing capacity of the dough improving and the fermentation persistence of the dough increasing. In addition, the stickiness increased as the turmeric powder content increased. However, there were significant differences among breads produced using different amounts of turmeric powder. Evaluation of the taste revealed that the TP3 group had the higher score than control score and TP7 had the lowest score. In overall preference, TP7 was especially low and the preference decreased as the content of turmeric powder increased.

  • This study presents a marketing communication strategy from the aspect of new consumption orientation. Consumer preference on ads media, on-line ads media, and WOM usage were examined for new consumption orientation groups. This study was executed in a question survey format. A total of 182 questionnaires were obtained and data were analyzed by PASW 18.0 and AMOS 7. The results were as follows. First, 8 types of consumption orientation factors were revealed; 'impulsive purchase', 'promotion oriented', 'social contribution', 'passive conformity', 'innovative', 'conspicuous', 'rational', and 'environmental conservation'. Then 4 groups were formed, 'Rational & Positive', 'Conspicuous Conforming', 'Positive Social Interested' and 'Low Price Oriented'. Second, communication responses were analyzed through consumption orientation groups. The 'Rational & Positive' group responded positively to every type of advertising media (especially new media). The 'Conspicuous Conforming' and 'Positive Social Interested' groups preferred traditional media such as TV, radio, and magazines; in addition, the 'Low Price Oriented' group liked only online banner ads. For WOM preference, the 'Rational & Positive' and 'Positive Social Interested' group preferred verbal consumer information like WOM. In distribution types, the just 'Positive Social Interested' group revealed a significant result for internet shopping malls. The results from this study will help establish marketing communication strategies based on the features of consumption orientation.

  • Sugar snap cookies were prepared with the addition of carrot powder (2~12%) as a source of dietary fiber. Analyses of physiochemical properties, rheology and sensory evaluation of the cookies were conducted. Increasing carrot powder content weakened the flour, as evidenced by decreased diameter and increased thickness, which resulted in decreased spread factor. The water content of the carrot powder-amended cookies and unamended flour was not significantly different. The pH and L values progressively decreased and a and b values progressively increased with increasing addition of carrot powder. Textural analysis revealed no significant differences in brittleness with carrot powder addition, even though brittleness did decrease with the addition of more carrot powder. Sensory evaluation revealed a preference for cookies prepared with 2~4% carrot powder, with decreased preference at powder concentrations exceeding 6%. Addition of a dried vegetable with high fiber content caused the dietary fiber to absorb much water content, resulting in decreased diameter, increased thickness and decreased spread factor. Therefore, it is deemed desirable to increase the spread factor by controlling the water content and adding emulsifiers so as to enhance the functionality and maintain the quality of cookies.

  • Objective: Understanding consumer perception of meat quality in developing countries is an important issue since consumer perception of quality could be highly variable. In the current study, consumers' purchasing preferences affected by marbling and perception of quality were evaluated in a survey study. Furthermore, consumers' preferences for degree of doneness were investigated using both survey and consumer panel studies. Methods: The study was carried out in two phases. Firstly, a survey was conducted in Adana Province, Turkey to collect data related to the attributes affecting consumers' meat purchase decision and consumers' degree of doneness preferences. In the second phase, boneless ribeye was used to investigate consumers' degree of doneness preferences in a consumer panel. In addition, proximate analyses of the samples were conducted. Results: The survey study using pictures of marbling illustrations indicated that higher degrees of marbling might be considered too fatty to be purchased by consumers. Consumers' perceptions regarding the relationship between marbling and beef quality further indicated that marbling might not be acknowledged as a cue of a higher quality meat. Nevertheless, the results of the importance of some attributes related to intrinsic and extrinsic quality cues showed that consumers were looking for the cues that indicated not only quality but also safety of the meat during meat purchase. The results of both survey and consumer panel studies revealed that consumers might prefer higher degrees of doneness while consuming meat since a majority of the consumers' preference of degree of doneness was at least well done. Conclusion: This study revealed that consumer purchasing preferences might vary between countries regarding marbling and perception of quality. Furthermore, higher degrees of doneness could be the preference of these consumers. Thus, further studies are needed to increase consumer satisfaction in these countries.

  • The study aimed to investigate the factors influencing genderless fashion preferences. The questionnaires were collected from men and women participants aged 20 to 49 living in Seoul City and Gyeonggi Province. Data analysis involved factor analysis, t-test, ANOVA, and regression analysis. The findings revealed that genderless fashion preference comprised four factors, namely individuality pursuit, deviation from norms, fashion pursuit, and social recognition pursuit. Self-esteem encompassed two factors positive self-esteem, and negative self-esteem. while sociocultural attitude toward appearance consisted internalization, and awareness. Second, positive self-esteem significantly influenced individuality pursuit and deviation from norms in genderless preference factors. Third, sociocultural attitude toward appearance had a significant effect on genderless fashion preference, with awareness particularly exerting a significant effect on individuality pursuit, fashion pursuit, and social recognition pursuit. Fourth, genderless fashion preferences exhibited differences based on gender role identity in factors such as individual pursuit, norm avoidance, and trend pursuit. Lastly, demographic characteristics such as age, education, occupation, and monthly income revealed significant differences in genderless fashion preferences. From the results of the study, it was found that consumers perceived individuality pursuit, fashion pursuit, and social recognition pursuit as important influencing factors of genderless fashion preferences. In addition, it is necessary to create an independent brand identity by developing various items to express consumers' individuality, differentiated brand concepts from other brands, and store displays.
