  • To characterize gene expression that is dependent on the strength of calorie restriction (CR), we obtained transcriptome at different levels of glucose, which is a major energy and carbon source for budding yeast. To faithfully mimic mammalian CR in yeast culture, we reconstituted and grew seeding yeast cells in fresh 2% YPD media before inoculating into 2%, 1%, 0.5% and 0.25% YPD media to reflect different CR strengths. We collected and characterized 160 genes that responded to CR strength based on the rigorous statistical analyses of multiple test corrected ANOVA (adjusted p value < 0.1 or raw p value < 0.0031) and Pearson correlation (|r| > 0.7). Based on the individual gene studies and the GO Term Finder analysis of 160 genes, we found that CR dose-dependently and gradually increased mitochondrial function at the transcriptional level. Therefore, we suggest these 160 genes are markers that respond to CR strength and that might be useful in elucidating CR mechanisms, especially how stronger CR extends life span more.

  • The purposes of this research were to segment consumer groups according to sportswear benefits sought and to find the differences among the groups in regard to domestic vs imported brand attitudes, internet vs department store attitudes, and sportswear purchasing behavior. The subjects used for the research were 773 male and female consumers who were residents in Seoul. The data were analyzed by factor analysis, cluster analysis, ANOVA, and Duncan test. The results showed that there were four sportswear benefit segments: figure compensation/ ostentation, individuality, comfort/function, and youth-oriented groups. Statistical analyses showed that the four sportswear benefit segments were different in regard to imported brand attitudes, department store attitudes, and sportswear purchasing behavior. For example, figure compensation/ ostentation segment had more positive attitude toward imported brands and department stores, considered design and advertisement important as sportswear selection criteria, and had a highest expenditure on sportswear purchase. The implications of the research were discussed.

  • This study was designed to identify the information sources of reference used by male college students. Theoretical framework is based upon social comparison theory, reference group theory, and Kotler's model of personal and non-personal sources of reference. The subjects were 287 male college students. The questionnaire were distributed to the school area and the commercial area such as Shinchon, Myung-Dong, and Apkujung-Dong in Seoul. Means, standard deviation, frequency, T-test, one-way ANOVA, and Duncan's multiple range test were applied for the analyses of data. The result of hyporthesis 1 showed that male college student utilize personal and non-personal sources of reference indiscriminately. The result of hypothesis 2 showed that male college students consult the socially high-proximal group such as a girl friend(a lover) and mother most actively. The result of hypothesis 3 found that male college students use position media most actively, especially in-store displays, followed by print media and broadcast media.

  • This study examined the effects of conditions of generation(0, 1, or 2 cognitive operations) and task difficulty in children's recall. Subjects were 40 children in each age group, 8-year-olds and 10-year-olds. Each subject was shown 12 simple or difficult multiplication problems in one of the conditions of generation. After a buffer task, subjects were required to recall correct answers to the problems in random order. The data were analyzed by ANOVA and simple main effect analyses. Results showed that generation effect(GE) occurred among children younger than 12, and GE improved with age. Learning from cognitive operations was more effective than learning through simple repetition. Easier tasks led to greater GE, a phenomenon explained by procedures used in this study.
