The purpose of this study was to investigate empirically the consumer behavior regarding the purchase of millinery items in relation to their evaluation criterion and demographic characteristics. The survey was carried out to 395 individuals in their 20s and over who were quota sampled according to age and gender. The collected data were statistically treated with the SPSS 12.0 program in terms of descriptive statistics, cross tabulation, t-test, one-way ANOVA, factor analysis, Cronbach's $\alpha$ coefficient and Duncan-test. The 20s and 50s over were more interested in hat products than other ages. Female consumers obtained the most information about hat products from store visits, TV and magazines. On the other hand, male consumers had it from the acquaintances and internet. Younger consumers more often utilized internet to have it. Their main purchase location was department stores. The younger purchased it more in traditional market, the older purchased it more in mega wholesale market or discount store. The consumers of hat products considered the intrinsic classification most when buying hats. The evaluation criteria employed by them were aesthetics, quality, and external attributes. Hat consumers were more concerned about aesthetics attributes than the other two criteria. Female consumers and consumers who are more interested in the hat and have a higher level of education and income considered aesthetics attributes most important.

The object of this study is to evaluate the Korean traditional food culture education program which was developed in the prior study. In order to evaluate the effect of the program on the students’ knowledge of traditional food culture and their food habit, the program was practiced for 82 students in 4 elementary schools located in Seoul and Kyungki province during 16 weeks from Mar 1, 2005 to July 23, 2005. The pretest and the post-test were performed using an evaluation tool which is composed of evaluation sections for the perception and knowledge of the Korean traditional food culture, Korean children’s food habit and food preference for the Korean traditional food and fast food. The validity of evaluation was proved through the control group in the pretest and the post-test. Descriptive analysis and paired t-test were performed using SPSS/WIN 12.0 Statistic Package in order to compare the results of the pretest with those of the post-test after the education. The perception of the students who took the class for the Korean traditional food was slightly improved (p<0.05) and their knowledge was also increased (p<0.001) after the education while no difference was found in the control group. Moreover, the subjects’ food habit (p<0.001) and their preference of the Korean traditional food (p<.05) were increased respectively but their preference of the Western fast food was decreased(p<.01). These results indicate that the education program evaluated in this study has the effect of altering the subjects’ food habit or food preference as well as of introducing the knowledge of the Korean traditional food culture.

In Korea, the human skin tests to evaluate the anti-wrinkles and whitening effect have been accomplished in accordance with the KFDA guideline. Regarding the data of the visual assessment and machinery evaluation of the results for the human skin test, unpaired t-test have been used in order to compare between the test and the control groups and paired t-test for the comparison of effects for before and after. Descriptive statistics such as frequency analyses was used for the questionnaire evaluation data. In many cases of the European and American clinical test centers, the methodology and the statistical analysis were similar to ours. But, the documentation obtained by repeated application from identical individual has high relation. For this reason, it is desirable to apply RM ANCOVA and RM ANOVA to a visual assessment and machinery evaluation. We suggested that RM ANCOVA and RM ANOVA is the new approach to statistical analysis of human test data of functional cosmetics.

For comparison of beef quality, four kinds of beef (Korean native cattle beef, dairy cattle beef, imported beef, cross-bred beef) were investigated through tenderness, juiciness and flavor related components measurement and organoleptic tests. Flavor related chemical components such as NPN, IMP, free fatty acid and free amino acids were analyzed, water holding capacity, contents of hydroxyproline and intramuscular fat were measured for evaluation of beef tenderness. Instron was also used for measuring beef tenderness as an objective method. Triangle test and descriptive analysis test were conducted for comparison and evaluation of preference of various beef samples. In hardness analysis using Instron, imported and cross-bred beefs had higher value than that of Korean native cattle or dairy cattle beef. Water holding capacity and pH of Korean cattle beef was higher than that of others. The intramuscular fat content of Korean cattle beef was highest, so it was expected juicier than other beef. In flavor related compound analysis, NPN content of Korean native cattle beef was the lowest, which shows it spent the least time among sample meats after slaughter. IMP, hypoxantine and inosine were most abundant in Korean native cattle beef. In free amino acids analysis showed that the proportion of basic acid and aromatic acid content of Korean native cattle beef was highest, whereas that of sulfur containing amino acid of imported beef was highest. TBA value of Korean native cattle beef was the lowest, and analysis of fatty acid composition revealed that the proportion of unsaturated fatty acid of Korean native cattle beef was higher than imported and dairy cattle beef, but similar to cross-bred beef. Organoleptic test was performed by triangle test and descriptive analysis. In triangle test, most panelist could distinguish Korea native cattle beef from imported beef and cross-bred beef, imported beef from cross-bred beef. In descriptive analysis which relys on subjective standards of panelists, there was no difference among beef in aroma, flavor and tenderness except juiciness. Even though contents of non volatile flavor compounds in Korean native cattle beef were higher than those of other beef samples, there were no significant differences in subjective panel test. The results showed that Korean consumers do not have common standards for beef quality evaluation.
