  • This study examined the actual consumption status and consumer preference for juk via questionnaire survey to provide useful basic data for the development of diversified commercial juk products. The survey data were collected from a target number of 450 participants living in the Seoul area. The subjects represented different age groups (over 20 years old) and both genders. Through a market survey based on five different retailers, which included juk-specialty stores, supermarkets, and local shopping marts, 17 kinds of commercial juk were chosen for the survey. Consumption frequency and purchasing factors were examined, along with preferences toward commercial juk products and areas for quality improvement. The results revealed that 54.0% of the respondents consumed commercial juk, and male consumers exceeded female consumers in number. It was also shown that those in their $20^{\circ}{\O}s$ consumed commercial juk products the least as compared to other age groups. With regard to commercial juk preferences by type of production mode, females especially preferred specialty store juk while males preferred retort juk sold in supermarkets or local shopping marts. In addition, 85.7% of the total respondents indicated that commercial juk should be further improved in quality, and they specifically noted possible improvements in the areas of 'choice diversification' and 'healthy juk' products. Therefore, one can conclude that by making such improvements, increase in consumption and further diversification of commercial juk products could be realized.

  • The objectives of this study are (1) to classify fashion consumers based on innovativeness and nostalgia and (2) to explore the differences in product purchase criteria, fashion information sources, and attitudes toward eco-friendly and fast fashion products among the identified groups of consumers. A total of 327 respondents were clustered into four distinct groups: (1) high innovativeness and low nostalgia, (2) high innovativeness and high nostalgia, (3) low innovativeness and high nostalgia, and (4) low innovativeness and low nostalgia. The four groups showed significant differences in the purchase criteria of quality, design, and brands and no difference in the criteria of functionality and washing methods. The four groups preferred different sources of fashion information: fashion magazines, people in the street, and salespeople, but did not differ in terms of social networking services (SNS) and in-store displays. While the four groups had significantly different attitudes toward eco-friendly fashion products, they did not show differences in attitudes toward fast fashion products, excluding usefulness. These meaningful results provide guidelines for developing more effective merchandising strategies for both eco-friendly and fast fashion products.

  • In this paper, we study the joint design of sampling inspections and service capacities for multi-products. Products of different defect rates which are either deterministic or random variables are supplied in batches after sampling inspection and rework. When supplied, all defective products that have not been inspected in batches are uncovered through total inspection and returned to service. We identify the optimal inspection policies and service capacities for multi-products reflecting the relationships between inspection rework costs and service provision costs. We also develope a marginal allocation algorithm for the optimal allocation of the limited total service capacity to products as well as inspection quantities.

  • Many online stores provide relevant products in product pages or other pages to attract customer interests. Association rules based on customer purchases and personalized recommendations are most prominently used ways of providing relevant products. Though there have been many studies to apply tags of products as metadata of the products, there are few studies to investigate contents similarities between the products and the suggested products. Thus, this study collects books in purchase associations and their tags in Amazon.com and assesses the similarities between the books. We found out that the contents similarities based on tags are similar among business, literature, and computer networks. And the similarity is also similar among the relevant books that have different ranks.

  • A validated and reproducible HPLC method was developed for the profiling and quantitative analysis of ginsenosides in commercial products available in North America. Analysis of 280 Panax ginseng and Panax quinquefolius products showed profiles indicative of the presence of ginsenosides in the majority of these products. However, the quantitative contents of the products vary greatly, not only in products of different formulations, but also of products within each of the fromulations examined.

  • This study was to develop a novel automatic system for measuring St$\ddot{o}$ckigt sizing degree and contact angle at a time. The conventional methods to measure sizing degree had serious problems in obtaining significant differences according to different dosages of a sizing agent, and moreover they disclosed unique limitation due to liquid types used and tester's subjectivity. However, the newly developed system could get reproducible results through total automation of all procedures including liquid dropping, image acquisition and measurement of both St$\ddot{o}$ckigt sizing degree and contact angle. For the St$\ddot{o}$ckigt sizing test, the automatic system could measure sizing degree with more definite differences according to different dosage of AKD, compared to the conventional method. For the contact angle test, the automatic system showed a similar trend to the conventional method but had smaller contact angles due to distortion of an image focus by a sheet curl than the conventional testing machine. The problem from the image out of focus due to specimen curl will be overcome with adopting a new specimen holder for the future system.

  • An empirical study was conducted on fashion cultural products, targeting foreigners from diverse cultures. Its purpose was to identify foreigners' attitudes toward fashion cultural products of which design sources were derived from the Korean culture. The quantitative research using questionnaires was targeted at Americans, Chinese and Japanese who visited Korea. The questionnaires were back-translated into different languages for completion by the test subjects. Out of a total of 424 surveys returned, 393 were deemed usable. As a result of data analyses using SPSS 12.0 and AMOS 5.0, we found that: First, two attitude factors, the authenticity and aesthetic elements, exerted a significant effect on the intent to purchase. However, the last attitude factor, care and carriage convenience, did not significantly influence the purchase intention. Second, there was no significant difference in the attributes regarded as important when purchasing fashion cultural product between people from the U.S. and Japan. However, people from China showed differences in the attributes compared to the U.S. and Japan. Third, we found that attitudes toward fashion cultural products were different among respondents of three countries. It was revealed that the Chinese liked Korea's fashion cultural products the most, followed by Americans and Japanese. This research is significant because investigating foreigners' attitudes toward fashion cultural products for reaching out to a broader market abroad would contribute to help building an market entry planning.

  • This study was conducted to determine sensory and chemical traits of reduced-fat frankfurters made with lean lamb or lean lamb/pork (50%/50%), fat from three different sources(pork fat, lamb fat or high-oleic sunflower oil) and added water products designated as L-P-15, LP-L-15, LP-So-15 and LP-P-15, according to lean meat type, source of added fat and target fat content and to compare such products with a similar reduced-fat product made with lean beef/pork (50%/50%) with pork fat(product designated as BP-P-15) and high-fat products made with lean beef/pork (50%/50%) or lamb/pork (50%/50%) with pork fat (BP-P-30 and LP-P-30). Actual fat contents of reduced-fat and high-fat products formulated for 15% and 30% fat were 17~18% and 28~31%, respectively, after processing. Processing yields were lower for all reduced-fat products than for the high-fat products. Trained sensory panelists rated LP-P-15 less intense in lamb flavor as compared to LP-L-15 and LP-So-15. Off-flavor intensity was positively correlated with lamb-flavor intensity (r=0.80), whereas frankfurter-flavor intensity was negatively correlated with lamb-flavor intensity (-0.88) and off-flavor intensity (r=-0.90). According to consumer panelists, LP-P-15 was as desirable in flavor as BP-P-15 or the two high-fat products (BP-P-30 and LP-P-30), while LP-So-15 and LP-L-15 were not. LP-P-15 and BP-P-15 were not notably different from their high-fat counterparts in juiciness and texture desirability and overall palatability. Regardless of fat content, meat type and fat source, there was little lipid oxidation when vacuum-packaged products were refrigerated for 12 weeks.

  • This study examined the dietitians 'perception and usage of processed meat products in institute foodservices. Out of 368 questionnaires collected from the subjects in school and business foodservices, 341 were chosen for statistical analysis after 27 were excluded for improper responses. According to the results, dietitian perceived the processed meat products food positively in terms of 'convenience'(3.94) and 'taste'(3.30), but negatively in terms of 'package'(275) and'additive'(2.01). In the frequency of usage, they used 'Ham'(2.51) the most frequently, followed in order by 'Wanja'(2.17), 'Dongas'(1.99), 'Tangsuyook'(1.82), 'Hamburg Steak'(1.71), 'Dduckgalbi'(1.59), 'Bacon'(1.50), 'Luncheon meat'(1.39), and 'Smoked meat'(1.30). The perception of processed meat products was more different according to institutes than dietitian. For dietitian, the frequency of usage was different according to their age and career, while for institute, it differed according to the type of management and the cycle of menu. Also dietitian placed the most importance on 'taste and preference'($90.1\%$) in buying and 'balance of nutrition'($72.0\%$) in cooking processed meat products (Ed- there is no respective comparison here). Finally, in the correlation analysis between perception and usage of processed meat products, the taste had positive correlation with 'Hamburg steak', 'Tangsuyook', and 'Dongas', the additive had positive correlation with 'Tangsuyook', and convenience had negative correlation with 'Tangsuyook' Based on the results of this study, the Processed meat products should be researched, developed, and supplied, with consideration for institution foodseuices.

  • Previous research has indicated that radish powder could be a suitable replacement for chemical nitrite sources in alternatively cured meat products. However, the effects of radish powder level on the physicochemical properties of cured meat have not been systematically studied. In this study, we aimed to investigate the effects of varying concentrations of radish powder and incubation time on the physicochemical properties and cured meat pigments of alternatively cured meat products. We divided our experimental setup into seven groups with different radish powder concentrations and incubation times: control (0.01% sodium nitrite), treatment 1 (0.15% radish powder and 2 h incubation), treatment 2 (0.15% radish powder and 4 h incubation), treatment 3 (0.30% radish powder and 2 h incubation), treatment 4 (0.30% radish powder and 4 h incubation), treatment 5 (0.30% celery powder and 2 h incubation), and treatment 6 (0.30% celery powder and 4 h incubation). The cooking yield, CIE a* values (redness), and total pigment levels were not significantly different (p > 0.05) between any of the alternatively cured treatments and the control. However, when 0.30% radish powder or celery powder was added to the products, the CIE b* values increased significantly (p < 0.05) with incubation time. At the same vegetable concentration, the nitrite content, nitrosyl hemochrome, and curing efficiency also increased significantly (p < 0.05) as the incubation time increased from 2 to 4 h, regardless of the types of vegetable powder. Among the meat products cured with radish powder, treatment 4 showed the highest increase in residual nitrite content, nitrosyl hemochrome content, and curing efficiency, but showed decreased lipid oxidation. Our results suggest that increased concentrations of radish powder and longer incubation times would be more suitable for producing alternatively cured meat products comparable to traditionally cured products treated with synthetic nitrite.
