The purpose of this study is to examine differences between 20s and 40s in visuospatial performance and brain activation areas using functional Magnetic Resonance Imaging (fMRI). Eight male college students in their twenties ($21.5{\pm}2.3$ years old) and six male adults in their forties ($45.7{\pm}2.6$ years old) who were graduated from college participated in the study. A visuospatial task was presented while brain images were acquired by a 3T fMRI system. Compared to the 20s the 40s showed lower visuospatial performance. There were more activations observed at the parietal and superior frontal areas at 20s compared to 40s. There were more activations observed at the middle frontal and occipital areas at 40s compared to 20s. The results of this study show that the lowering of visuospatial performance with aging was correlated to the decrease of activation area at the parietal lobe and the change of activation area at the frontal lobe.

We previously used Southern blot analysis to detect restriction-length polymorphisms between male fertile and cytoplasmic male sterile (CMS) cytoplasms at the coxII and atp6 loci of the mtDNA of Capsicum annuum L. Two copies of atp6 were found in each male fertile and CMS pepper lines. Interestingly, one of the copies of atp6 in CMS pepper was a 3'-truncated pseudogene. The open reading frame of the coxII gene was the same in the fertile (N-) and CMS (S-) lines. However, the nucleotide sequence in the S-cytoplasm diverged from that in the N-cytoplasm 41 bp downstream of the stop codon. To develop CMS-specific sequence-characterized amplified region (SCAR) markers, inverse PCR was performed to characterize the nucleotide sequences of the 5' and 3' flanking regions of mitochondrial atp6 and coxII from the cytoplasms of male fertile (N-) and CMS (S-) pepper plants. Based on these data, two CMS-specific SCAR markers, 607 and 708 bp long, were developed to distinguish N-cytoplasm from S-cytoplasm by PCR. The CMS-specific PCR bands were verified for 20 cultivars containing either N- or S-cytoplasm. PCR amplification of CMS-specific mitochondrial nucleotide sequences will allow quick and reliable identification of the cytoplasmic types of individual plants at the seedling stage, and assessment of the purity of $F_1$ seed lots. The strategy used in this report for identifying CMS-specific markers could be adopted for many other crops where CMS is used for F1 seed production.

With increasing concerns about environmental issues that can result from apparel and textile disposal, the recycling methods for discarded fashion products have gained significant attention. As the influential drivers of consumer purchasing and consuming behaviors, fashion innovativeness and fashion involvement can play important roles in forming consumer attitudes toward apparel recycling. The purpose of this study was to (1) investigate consumer attitudes toward three different methods of apparel recycling including resale, reform, and donation, (2) examine the effects of fashion innovativeness and fashion involvement on consumers' apparel recycling attitudes, and (3) identify gender difference in the relationships among fashion innovativeness, fashion involvement, and recycling attitudes. Using a web-based survey, data were collected from 281 Korean consumers who were in their 20s and 30s. Overall, both male and female consumers revealed the most favorable attitudes toward apparel recycling through donation, followed by reform, and resale. The findings suggest that consumer traits, such as fashion innovativeness and fashion involvement, are important factors predicting male consumers' apparel recycling behaviors. Those male consumers who perceive fashion as important were more interested in apparel recycling than those males who put low importance on fashion. Male fashion innovators were less likely to recycle their unused and old apparel items. Further studies identifying antecedents of female consumers' attitudes toward apparel recycling are warranted.
