The purpose of this study was to estimate coffee consumption and it's relationship to blood pressure and blood lipid profiles in Korean adult men and women. Antheropometrics, dietary intake by 24-hour recall, and serum lipid profiles were measured in 354 subjects. The average subject ages for the age ranges of $20{\sim}49$, $50{\sim}64$, and over 65 years, were 39.7, 57.5, and 70.6 years for the men, and 40.7, 56.9, and 70.9 years for the women, respectively. Mean height and weight were significantly higher in the men and decreased with increasing of age. Thirty percent and 28% of the men and women, respectively, consumed coffee. The proportions of coffee consuming subjects in the age rangers of $20{\sim}49$ years(34.9%) and $50{\sim}64$ years(35.6%) were significantly higher than in the group over 65 years(11.5%). The mean daily intakes of food and energy were showed the same results according to sex and age. Mean daily coffee intake was not significantly different between the men and women, but it was significantly lower in the over 65 age group. Systolic blood pressure was significantly higher in the men and increasing age. The atherogenic index was significantly higher in the $20{\sim}49$ year-old men, and in the women over 65 years. There were no significant correlations among coffee consumption, blood pressure, and the serum lipid profile. In conclusion, the daily coffee consumption by adult men and women, with the exception of the elderly, was $50{\sim}90m{\ell}$, and it was not significantly correlated to blood pressure or blood lipids.

A dynamic model was developed to predict the Escherichia coli cell counts in pig trotters at changing temperatures. Five-strain mixture of pathogenic E. coli at 4 Log CFU/g were inoculated to cooked pig trotter samples. The samples were stored at 10℃, 20℃, and 25℃. The cell count data was analyzed with the Baranyi model to compute the maximum specific growth rate (μ_max) (Log CFU/g/h) and lag phase duration (LPD) (h). The kinetic parameters were analyzed using a polynomial equation, and a dynamic model was developed using the kinetic models. The model performance was evaluated using the accuracy factor (A_f), bias factor (B_f), and root mean square error (RMSE). E. coli cell counts increased (p<0.05) in pig trotter samples at all storage temperatures (10℃-25℃). LPD decreased (p<0.05) and μ_max increased (p<0.05) as storage temperature increased. In addition, the value of h₀ was similar at 10℃ and 20℃, implying that the physiological state was similar between 10℃ and 20℃. The secondary models used were appropriate to evaluate the effect of storage temperature on LPD and μ_max. The developed kinetic models showed good performance with RMSE of 0.618, B_f of 1.02, and A_f of 1.08. Also, performance of the dynamic model was appropriate. Thus, the developed dynamic model in this study can be applied to describe the kinetic behavior of E. coli in cooked pig trotters during storage.

This study is to provide basic information on clothing fitness necessary to develop apparel products for Korean companies that want to enter or have already made inroads into the Chinese market. In an effort to serve this purpose, a standard upper torso body model for Chinese women was established by applying the Rohrer Index and Size Designation of Clothes - Women of GB/T 1335.2-1997 to Chinese women in their 20s to determine body types and its characteristics. First, according to the result of applying the Rohrer Index to categorize body types, Type 1 showed the longest vertical body length and a short horizontal length with the lowest degree of flatness. Type 2 was a standard body type with a height of 158.73cm, weight of 53.02kg and the Rohrer Index of 1.32. Type 3 had a thick and flat body shape that had the highest degree of flatness and the shortest vertical length in its upper torso among all three types of body. Second, F-test was conducted on 4 distinctive body types obtained from comparing obesity scores to verify differences in body shapes for different degree of obesity. The test result indicated significant differences in 3 of the 4 body types and showed different structural components for different degree of obesity. Third, the result of comparing correlational distributions of body types and height range, and body types and degree of obesity for all and specified age groups revealed that about 33.30% of the body types appeared in Type2-A followed by 20.18% in Type1-A, 18.40% in Type2-Y and 7.91% in Type1-Y respectively. Body types and degree of obesity for two different age groups were most frequent in Type2-A. For the group of young women in their early 20s appeared the most in Type2-A, Type1-A, Type2-Y and Type 1-Y respectively and young women in late 20s were frequent in the order of Type2-A, Type2-Y, Type1-A and Type1-Y.

The objective of this study is to investigate the fit preference tendency for ready-to-wears(jackets, skirts, and slacks) of adult women and to find out the respective differences by the age range and the obesity level. The study method was the questionnaire survey with the subjects of 699 women of 20 up to 59 years of age. The questionnaire is composed of fit preference tendency, physical measurements, age, and occupation. For the data analysis, SPSS 90. program was used, and descriptive statistics, Crosstabs, ANOVA, Duncan's test, and t-test were conducted. The findings are as follows. 1. Regarding the fit preferred for each part of jackets, skirts, and slacks, among ready-to-wears, the 'thing with some extra width' in every part was most favored, followed by the 'thing fitting perfectly'. 2. The differences were found in the fit preference tendency by the age of adult women. The fit preference tendency was higher among those in their 20's than among those of the other age range, and those in their 30's and 40's preferred the clothes with less extra width in comparison with those in their 50's. 3. The differences were also found in the fit preference tendency by the obesity level of adult women. The fit preference tendency was high in the order of the emaciation, normalcy, and obesity types. 4. The fit preference tendency was found to be more affected by the obesity level than by the age. The fit preference tendency by the obesity level of each age range showed the differences in all of the age range. However, the normal type did not show the preference difference among the age ranges, in the fit preference tendency by the age range of each obesity level. Clothing manufacturing firms should understand the characteristics of consumers, such as their age, body type, extra width preferred, to provide the consumers of target market with suitable leeway, and they should design the clothing products which meet up these needs in style and silhouette.
