This study compares the expected values of appearance management for the suit buying behavior of men in two age groups: (20s-30s and 40s-50s) to investigate the effect of male consumers' expected values in regards to appearance management on the purchase behavior of men's suits between two generations. A survey was carried out with male consumers between the ages of 20 and 50; a total of 135 responses were analyzed by descriptive analysis, factor analysis, a reliability test, an independent samples t-test, MANOVA, ANOVA, and regression analysis. The results of this study were as follows: 1) From a result of the factor analysis on male consumers' expected value of appearance management and the information sources and purchase evaluative criteria for buying men's suits, each of three variance assessments clearly showed factorial structures. 2) There were significant differences between those in their 20s-30s and those in their 40s-50s in terms of male consumers' expected values of appearance management, their information sources, and their purchase evaluative criteria when buying men's suits. 3) As a result of looking at the differences in the effects of expected values of appearance management on men's suit buying behavior according to age (generation), the younger generation in this study showed that men's suit purchasing tendency was affected by the managing appearance factor for internal reasons such as enjoyment and self-satisfaction. On the other hand, the assessment of the older generation revealed that appearance management for external reasons such as showing social power, good human relationships, and conformity influenced their suit purchase behaviors.

This study is an initial report of actual wearing conditions and attitude based on a survey of wearing outdoor wear for men and women in their 30s to 50s who enjoy daily leisure sport activities. Most middle-aged men and women who enjoy outdoor activities were interested in new trends and clothing styles. The greatest area of interest was health(42.9%), followed by leisure and sports(38.4%); in addition, hiking(40.2%) was the most popular outdoor activity. The majority of subjects participated in outdoor activities for over 5 years(34.4%). The highest frequency of outdoor activities was conducted once or twice a month, and it took one to three hours for each activity. Nearly half of the respondents( 47.7%) answered that the goal of outdoor activities was to maintain their health. Subjects in their 40s and 50s were more equipped in their outdoor activities and in their 50s made ongoing investments despite costs. When wearing clothing, the subjects placed a priority on design(in the case of subjects in their 30s) and comfort(for subjects in their 40s and 50s). This survey shows that the subjects emphasized access to outdoor wear and equipment. In all age groups, the biggest complaint about outdoor wear was price; in addition, they were unsatisfied with the length and the sleeves of outdoor jackets. Outdoor wear will draw a positive attention for its practical use of clothing if it is developed according to consumer demands based on functionality for outdoor activities and convenience in daily life.

This study was carried out to investigate the fast food consumption patterns classified by age in Busan. The survey was conducted from October 15 to November 15, 2006 by questionnaires and data analyzed by SPSS program. The results are summarized as follows: Forty one point five percent of the elementary group, 40.5% of the high school group, 24.1% of the 30's, 35.0% of the 40's and 18.1% of the 50's took fast foods over once a week. Seventy two point five percent of the elementary group, 61.5% of the high school group, 16.8% of the 30's group, 10.0% of the 40's, and 14.6% of the 50's preferred fast foods. There was a significant difference in the basis for selecting menus among the groups. The most important basis for selecting menus was 'price' in the elementary group and the high school group, but was 'preference' in the adult groups. As their age increased, they spend more money for fast food. Forty six percent of the elementary group and 49.5% of the high school group, 32.1% of the 30's, 36.5% of the 40's, 34.7% of the 50's thought that fast food can substitute for a meal. The age affected significantly the substitutability for the meal of the fast food (p < 0.001). In the high school group, the ratio of skipping breakfast is higher than in the other age groups. Dietary attitude has direct effects on the preference of the fast foods. Nutrition knowledge, degree of unbalanced diet and obesity rate have direct and indirect effects which were mediated by dietary attitude. Nutrition knowledge showed the greatest total causal effect in relation to the preference of the fast foods. Therefore, nutrition education for the subjects is needed to encourage them to choose more nutritious food and have healthier dietary pattern.

Polycaprolactone (PCL) and thermoplastic starch (TPS) blends were prepared. Mechanical properties, thermal property, water absorption, biodegradability by composting and surface morphology of PCL/TPS blends were investigated. The compositions of PCL/TPS blends were 90/10, 80/20, 70/30, 60/40, 50/50, 40/60, 30/70, 20/80, and 10/90. Strength and elongation at break decreased as the content of TPS increased, while modulus increased. DSC thermogram of TPS showed two glass transition temperatures (T$_{g}$ ) at 23$^{\circ}C$ and 126$^{\circ}C$. And TPS proved to be an amorphous polymer because there was no endothermic peak due to the melting of starch crystal. The unchanged melting temperatures and T$_{g}$ 's of PCL/TPS blends revealed that PCL and TPS were not miscible. All of the blends were found to be mechanically compatible but phase separated in each other. After 45 days composting, the biodegradability of PCL was 44% and that of PCL/TPS blends increased as the contents of TPS increased.

This study provided data for classifying and characterizing the lower half of the body shape for obese adult men in their 30s and 40s. Data of 492 adult males who were obese with a WHO criteria of >25 BMI were used for analysis. The results of the study are as follows. Six factors extracted from the factorial analysis as independent factors for cluster analysis were classified into three types. Type 1 (65.4%) had the lowest height of the lower half of the body with short circumference and length. Type 2 (20.3%) had the lowest height of the lower half of the body with the largest thickness, width and circumference from the back to the hip, but short in length. Type 3 (14.2%) had the lowest height of the lower half of the body with medium height and waist-height; however, the curve from the waist to the hip was the largest with the largest waist circumference, hip circumference, and width and thickness of the lower half of the body. This study will help to design a slack pattern that utilizes body shape characteristics of men in their 30s and 40s. In a follow-up study, we analyze the slack pattern and educational pattern by the company and study the necessity for a slack pattern for obese males.
