Purpose - The purpose of this study is to investigate the difference in the degree of significance and satisfaction perceived by college students and ordinary consumers on the HMR product attributes. Comparison of the difference on HMR product attributes between ordinary consumers and college students who belong to the current and future consumption groups of HMR will provide information for clear marketing strategies and PR on target consumers from the aspects of companies. Also, overall difference on HMR was investigated through IPA(importance-performance analysis) on significance and satisfaction with each product attribute. This result will provide information to food companies that produce or supply HMR products to be supplemented and improved. Finally, IPA was conducted between groups on product attribute to find which difference exists between groups. This result is also expected to provide crucial information to companies as suggested in the first purpose. Research design, data, and methodology - The procedure of analysis is as follows. First, independent sample t-test was conducted on the significance and satisfaction on HMR product attributes. Second, with using IPA, the significance and satisfaction on HMR product attributes of the respondents were checked to investigate marketing strategy direction on overall HRM products. Third, the difference between generations was verified using IPA on the college student and consumer groups. According to this result, the direction of marketing strategy on HRM products was to be proposed to food companies. Results - It was known that consumers consider HMR product attributes statistically and significantly such as nutrient content(nutrition), country of origin, brand, main raw material, packaging, and awareness of manufacturer. They keep after purchase more importantly than college students who considered only volume and price than consumers. In comparison with the difference in satisfaction on HMR product attributes, the college student group was more satisfied than ordinary consumers only in flavor, condition of food additives, and volume. Also, HMR related food companies must maintain taste, cooking method, manufacturing date, expiration date, and safety on current products continuously. Finally, as a result of analysis from the groups, the attributes such as cooking method, manufacturing date, expiration date, and safety were considered significantly with high achievement by the two groups. It was known that college students considered food texture to be important, but consumers considered storage method to be important after purchasing it. Conclusions - There is necessity to differentiate effectiveness of products when releasing HMR products subject to consumers and college students. The result will give great assistance to the improvement of companies, produce or supply HMR products. It will also provide entry strategies on target groups of companies that are planning for entry. The factors that consumers commonly considered not to be significant were brand, package form(appearance), cooking time, and sale(purchase) location, which were found in the comparison with the groups that awareness about manufacturers and storage method after purchase corresponded to college students and that distribution route corresponded to ordinary consumers.

There has been an increasing public concern about environmental safety and human health of field crops while customer consumes more and more field crops, to which overdose and residual chemicals were applied. As a solution for the problems, construction of sustainable agroecosystem is spreading out to pursuit the economic value of agricultural management as well as to meet environment concern. Public has extended their understanding on the preservation of environment and safeness of agricultural products, and governmental policy toward sustainable agriculture drives rapid increase of the production of sustainable agricultural products. Under this circumstances, it is time to encourage more consumption and to activate market system for the sustainable agricultural products. This study was initiated to diagnose the problems and future direction of domestic sustainable agriculture by analyzing the overall opinions of consumer on the sustainable agriculture. The results are as follows: The pursuit of low input management is a prerequisite to creat high valued agricultural products, and serious consideration should be taken to produce clean crops using natural products. Consummers are willing to pay 10∼50% more prices if the products get certified by official eco-label programs. It is believed that practice of sustainable agriculture using biopesticide and natural pesticide would accelerate the rapid extension of this pro-environmental agricultural management. To activate production and consumption of sustainable agricultural products correct informations on safety should be addressed to customer, and confidence has to be brought about from customer. This could be done by obtaining various and efficient distribution route, product competency for quality, upgraded sales strategy, maximum utilization of certificate system, and practice of recall system, so on.

Pine needle powder has medical and functional uses. In this study, cookies were prepared using different 0.5%, 1%, 3%, 5% of pine needle powder. The total phenolic content was measured by the Folin-Ciocalteu method, and antioxidant activity was evaluated by DPPH assay. The antioxidant activity was highly correlated with the total phenolic composition of pine needle cookies (r=0.989). In addition, the quality characteristics of the pine needle cookies were estimated based on the bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations. The bulk density of the dough and the hardness, total polyphenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing pine needle powder, while the pH of the dough, spread factor and L values of the cookies decreased with increasing pine needle powder content (p<0.05). Additionally, the consumer acceptability scores for the 3% pine needle cookie groups ranked significantly (p<0.05) higher than those of the other groups in appearance, taste, flavor, texture and overall preference. Taken together, the results of this study suggest that pine needle powder is a good ingredient for increasing the consumer acceptability and the functionality of cookies.

This study investigated the antioxidant properties of yangha(Zingiber mioga Rosc) and quality characteristics of kimchi with added yangha during a 21-day fermentation process at $4^{\circ}C$. Yangha was added to salted cabbage at concentrations of 0, 5, 10, and 15% (w/w). The quality characteristics of kimchi with added yangha were determined by measuring pH, salinity, mineral contents, lactic acid bacteria amounts, color value and sensory evaluation. From the results, total phenolic ($3.85{\mu}M$ quercetin equivalent/g) and total flavonoids ($0.49{\mu}M$ quercetin equivalent/g) contents were measured in yangha. The number of lactic acid bacteria of kimchi with added yangha significantly increased with increasing yangha content, especially 10%. The brightness value increased with increasing yangha content. However, the redness tended to decrease by the addition of 10% and 15% yangha. The consumer acceptability score for the kimchi with added 10% yangha ranked significantly higher than that of the other groups in overall acceptability, taste, flavor, and color(p<0.05). From these results, we suggest that yangha may be used as a natural antioxidant and that it is a good food ingredient for increasing the functionality and consumer acceptability of kimchi.

The purpose of this research is to study the cause of obstruction in various knit pattern structures by understanding the needs of the customers, and to develop knitted fabric goods that satisfy the individual taste of consumers and that reflecting the latest fashions. Actual conditions of the manufacturer's designing processes must be examined. In addition, a comparison analysis of fashion sensibilities and preferences between producers and consumers had been made in order to study developing knit pattern structures. Questionnaires and interviews had been used as research methods. The research involved two groups: one group consisted of 57 producers, which included designers, programmers, and merchandisers working for a knit manufacturer in Seoul, while the other group consisted of 74 consumers, which included students with knitted fabric design as their major and those who have working knowledge of knitted fabrics. For a more accurate evaluation, 28 out of 150 patterns have been selected through a preliminary study conducted by 24 designers. On the 28 knit patterns, a sensibility evaluation had been made through the use of the sense of sight and sense of touch, which was followed by a frequency analysis, cluster analysis, and t-test using SPSS 12.0. The results are as follows: the fashion sensibility evaluation on knit patterns showed that structures, such as racking II or lace II, are typically elegant ('elegance'), while structures, such as links I or racking I, are typically 'active.' Furthermore, a 'country' image was displayed in structures such as cable I, cable II, and miss II. Links I appeared as 'sophisticated'. Miss I and milano were said to have 'modem' images. Lace II was regarded as 'ethnic', while racking II was said to have a 'romantic' image. 2:1 rib and milano were generally thought to be manly ('manish'). The fashion sensibility scale for each knit pattern has been made based on the above results. Based on producer and consumer responses, the sensibility evaluation on knit pattern structures showed that the two groups had similar preferences in knit pattern structures. Therefore, the fashion sensibility scale developed in this study can be used as a basic data for structure development when designing knitted fabric goods.

We investigated the feasibility of incorporating Aster yomena powder into cookies as a value-added food ingredient. In this study, we assessed the quality characteristics and antioxidant activity of cookies containing various concentrations (0, 3, 5, 7 and 9%) of Aster yomena powder(AYP). For the analysis, quality characteristics such as density and pH of dough, spread factor, moisture content, color(L, a, b), hardness, DPPH radical scavenging activity and sensory properties were measured. The Hardness and DPPH radical scavenging activity of the cookies significantly increased with increasing concentrations of AYP, whereas pH and density of the dough, L value of the cookies significantly decreased. The results of sensory properties showed that cookies made with 3% and 5% AYP did not differ significantly from the control in color, taste, and overall quality. Texture scores for the 3% and 5% AYP groups ranked significantly higher than those of the other groups. Taken together, the results of this study suggest that AYP is a beneficial ingredient for increasing the consumer acceptability and functionality of cookies. The quality characteristics of the 3% and 5% added samples exhibited significantly similar or higher values as compared to those of the controls, raising the possibility of developments in health-functional cookies. The results of the sensory evaluation produced very significant values for color, appearance, texture, and overall quality of instrumental analysis.

Black rice bran powder has potential medical uses and functionality. In this study, we assessed the antioxidant activity and quality characteristics of cookies containing various concentrations (0, 1, 3, 5, 7, and 9%) of black rice bran powder. To analyze quality characteristics, proximate composition, fatty acid composition, amino acid composition, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. Black rice bran cookies (7%) contained more crude protein ($10.67{\pm}0.33$%) compared to control ($5.84{\pm}0.06$%). The total unsaturated fatty acid contents of the control and 7% black rice bran cookies were 30.44 and 30.81%, respectively. The amino acid content of 7% black rice bran cookie was higher than that of control. Bulk density of the dough, moisture, spread factor, total polyphenol content, and DPPH free radical scavenging activity of the cookies significantly increased with increasing content of black rice bran powder, whereas pH of the dough, loss rate, leavening rate, and L values of the cookies decreased. Additionally, consumer acceptability scores for the 7% black rice bran cookie group ranked significantly higher than those of the other groups in terms of appearance, taste, flavor, texture, and overall preference. Taken together, the results of this study suggest that black rice bran powder is an effective ingredient for increasing the consumer acceptability and functionality of cookies.

This study was performed to develop yut(Korean Traditional Candy), products using dried-persimmon, with the ratio of 5, 10, 15, 20 and $25\%$, and the quality characteristics were investigated. The proximate compositions of dried-persimmon were $29.67\%$ moisture, $1.76\%$ crude protein, $0.18\%$ crude lipids, $1.31\%$ crude ash and $3.92\%$ crude fiber, respectively. Brix of yut products were ranged from $81.5\%$ to $83.0\%$. With increasing the amount of dried-persimmon, hunter's color values of Land b were reduced. In the texture property, the addition of dried-persimmon increased hardness, fracturability, gumminess and chewiness, while decreased adhesiveness. Judging from texture, taste and overall acceptability of the yut product, the recommended substitution level of dried-persimmons was $10\%$. In consumer sensory score, the $twenties\~sixties$ gave high score of color, while the $thirties\~fifties$ gave high score of sweetness. Overall acceptance of yut products of $dried-persimmon$ were good in old-age consumers.
