This study was designed to evaluate the quality characteristics and antioxidant properties of Longanae Arillus powder (added in the ratios of 0%, 25%, 50%, 75%, and 100%), which is traditionally used to render the product more suited to the modern consumer's taste for the compound Longanae Arillus Dasiks. As the consumer consumption of the proportions of Longanae Arillus increases, the moisture content and pH of the Dasik supplemented with Longanae Arillus decrease, while at the same time, a soluble solid content increases (p<0.001). The color value showed the decrease in L and b values with the increase in Longanae Arillus content, and the increase in the value of the compound with the addition of Longanae Arillus (p<0.001) can be noted. The mechanical texture of Dasik was increased by the addition of Longanae Arillus considering its hardness, adhesiveness, cohesiveness, springiness, and chewiness (p<0.001). In the sensory evaluation of the Longanae Arillus Dasik showed that people expressed an overall preference at the addition of Longanae Arillus, such as noted as being preferred with 50% in color, flavor, taste, texture, and overall acceptance of the compound (p<0.001). Regarding the antioxidant activity of Longanae Arillus Dasik, the total phenolic, flavonoid contents, DPPH radical scavenging activity, reducing power, and superoxide anion levels were found to increase with the addition of Longanae Arillus (p<0.001) with its consumer use. It is believed that Longanae Arillus Dasik, is most preferred to be added at the concentration of 50% during the Dasik preparation.

This research evaluated and analyzed the level of acceptability of spinach according to blanching time by testing consumer taste of corresponding countries for the purpose of globalizing Korean food. General taste, appearance, flavor, and texture of spinach blanched for 20 seconds were highly evaluated by Koreans and Japanese ($p$<0.05), who are used to the method of slightly blanching, mixing, and eating spinach. On the other hand, general taste, appearance, flavor, and texture of spinach blanched for 5 minutes was highly evaluated by the French ($p$<0.05), who are used to eating boiled spinach. Concerning the result of JAR, there were clear differences in hardness and boiling level according to country among spinach samples, even though they were blanched for the same time and mixed with the same spices. Koreans and Japanese evaluated that hardness and boiling level of spinach blanched for 20 seconds were proper, whereas the French evaluated that spinach scalded for 20 seconds was too raw and crispy. Under the same context, French consumers evaluated that hardness and boiling level of spinach blanched for 5 minutes was proper, whereas Koreans and Japanese evaluated that spinach blanched for 5 minutes was boiled too much. These results show that familiarity level is an important driver of affecting the preference levels for three kinds of spinach according to country.

The purpose of this study was to investigate consumer preferred formats of nutrition labels: the type of nutritional information provided on the labels. A survey was conducted on 222 housewives between the age of 20 and 65 in Daejeon city in 1998, using an interview questionnaire showing illustrated nutritional label formats. Among twelve nutrients and caloric values listed on the nutrition labels, the housewives ranked their interest in the items in the following order of calorie (58.56%), calcium (56.76%), cholesterol (54.05%), protein (39.19%) and vitamin C (36.04%). The majority of the subjects (69.37%) checked labels when they bought milk or dairy products, whereas only 8.11% looked at labels when they bought Ramyon or noodles. Most of the subjects (90.99%) preferred products with labels with nutritional information as compared with products without labels. this was especially so true of the younger individuals and of pc-ople who checked food labels more frequently. The subjects preferred labeling which described the nutrient content per Package (55.41%), sewing size (32.88%) and food weight of 1009 (11.71%) as a standard nit. Generally, they prefer-red a simplified list to a detailed list of the number of nutrients, a figure graph to bar graph in nutrition claim, vertical bar graph to horizontal bar graph showing the nutritional content of foods and a web-type graphic format to a radiation-format when describing the item's percentage of the Korean RDA's nutrient content. The subjects who checked labels frequently especially preferred detailed list, while housewives with job or with unhealthy family members preferred a simplified list and graphic, rather than a numerical display. From this result, it is suggested that providing consumers with more nutrients information in a more easily understood graphic format would encourage the consumers to check nutritional labels. Therefore this should be considered when developing the regulations far nutrition labeling or when educating the Public about nutrition. (Korean J Community Nutrition 8(2) : 220∼230, 2003)

This study was carried out to investigate consumer's preference and purchase behavior of pork including perception of brand-pork in Korea. A total of 504 respondents were surveyed and collected from December, 2007 to February, 2008. Among total respondents, 62.55% (n=314) responded that they liked the pork and respondents who were higher education level showed higher preference (p<0.05). Majority of consumers (61.16%) did not like imported pork. In addition, one who had lower education level and living in rural area disliked more the imported pork. Most consumers preferred to the belly (58.57%) and results indicated that the people who were higher education level preferred a discount mart but who were living in rural area preferred a butcher's shop. Among the purchasing area, a big discount mart was the most preferred (44.64%) and this was also different among the education level (p<0.001) and living areas (p<0.05). The consumers preferred to purchasing a 600 g pack for a single purchase. Among total respondents, 42.71% of consumers responded that their priority was reliability of meat quality on choosing the place for purchasing the pork, and the significant difference was highly found in living area groups (p<0.001). The perception of carcass grading system was common scores with the average of 2.79, and there was highly significant difference among education level groups (p<0.001). The average of 3.50 among 5 points for branded pork were evaluated by a total of consumers but the significant differences were not found in all three groups.

The purpose of this study is to find out characteristic of a product which has the most influence when consumer makes a purchase, and analyze if actual consumers make a purchase with recognition of the brand difference between PB and NB brands using conjoint analysis. As a result, the main factor which consumers consider when they purchase a product is the quality but the factor for brands (NB or PB) do not have an effect on their purchasing. The reason why consumers little consider a factor for PB or NB is that they do not have much knowledge of PB and they recognize the PB as a "me-too" product of NB. Therefore, retailers should develop more differentiated product in order to be recognized by consumers.

The advent of an aging society has raised the necessity for housing development to meet the growing demands of baby boomers expected to act as the main consumers in the future housing market. This study aims to identify the characteristics of apartment houses favored by baby boomers in their post-retirement plans. Based on a literature review and survey, the study is targeted at a certain baby boom generation residing in mid- sized and large-sized apartments with a floor space of more than 30 pyeong in Gangnam, Seoul. The study reveals that baby boomers favor an active post-retirement life where they can enjoy proper leisure without considerable change in daily routines, and for that reason they choose an apartment house well equipped with neighboring, convenient facilities for their post-retirement. Their housing size shows a downward tendency in response to changes in economic conditions and number of family members living together. Health-related factors such as a comfortable natural environment and greenery also play a key role in their residence selection. Their regional preference is divided into the downtown and suburbs, and thus it will be necessary to satisfy the needs of these two consumer groups in the future housing market. This study lays the foundation for offering basic materials for the development and marketing of apartment houses.

The objective of this study is to analyze the determinants of at-home laver consumption expenditures using the data from a survey of households implemented in 2009. It happened that non-response ratios of monthly expenditures on dry laver and flavored laver among sampled households are 18.8% and 25.6%. Accordingly, this study tries to analyze the determinants affecting at-home laver consumption expenditures by using type II tobit model, one of sample selection models, to deal with sample selection bias caused from non-response data. Analysis results show the age variable positively affects expenditures on dry laver but negatively contributes to expenditures on flavored laver. In addition, the household size, the household's income, the degree of preference for laver have positive relationships with both expenditures. Household size elasticity and income elasticity of the expenditure on dry laver are estimated as 0.220 and 0.251. In the case of flavored laver, these elasticities are estimated as 0.484 and 0.261. Such analysis results can provide information on division of the at-home laver consumption market into groups with high willingness to expense and implementation of detailed marketing strategies to increase at-home laver consumption. The methodology of this study can be applied to consumer preference analysis on other marine products and other analyses on sample with non-response data in the fishery research.

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.
