The purpose of this study was to investigate the knitwear preferences and purchase behaviors of university students. The subjects were 493 university students in Daejeon and Chungnam Provinces. The method of this study was a survey and measurement instruments were 34 stimuli which were manipulated pullover patterns and shapes and self-administrated questionnaire with knitwear design preference items and knitwear purchase behavior items. Data were analyzed by factor analysis, frequency analysis, Cronbach'${\alpha}$, t-test, ANOVA and $Sch{\acute{e}}ffe$ test using SPSS program. The results of the study were as follows. First, university students most preferred achromatic colors, pastel tones, solid patterns, and 100% cotton. Second, as for knitwear purchase behaviors, university students considered the esthetical factor to be most important among 4 dimensions (comfortable, esthetical, economical, and conspicuous factors) as important purchase criteria, and they used internet web sites for knitwear purchases. Third, there were significant differences in preferred pullover shape depending on neckline shape, neck depth, sleeve shape and clothing length. University students preferred the classic pullover design with V neckline, normal neck depth, set-in sleeves and normal length. Fourth, university students preferred the cloud motif and riding man motif among the 9 Baekje traditional motifs and one point small pattern on the left chest and crosswise bending pattern for pattern arrangement.

The wild-type and temperature-sensitive (ts) repressor genes were cloned from the temperate mycobacteriophage L1 and its mutant L1cIts391, respectively. A sequencing analysis revealed that the $131^{st}$ proline residue of the wild-type repressor was changed to leucine in the ts mutant repressor. The 100% identity that was discovered between the two DNA regions of phages L1 and L5, carrying the same sets of genes including their repressor genes, strengthened the speculation that L1 is a minor variant of phage L5 or vice versa. A comparative analysis of the repressor proteins of different mycobacteriophages suggests that the mycobacteriophage-specific repressor proteins constitute a new family of repressors, which were possibly evolved from a common ancestor. Alignment of the mycobacteriophage-specific repressor proteins showed at least 7 blocks (designated I-VII) that carried 3-8 identical amino acid residues. The amino acid residues of blocks V, VI, and some residues downstream to block VI are crucial for the function of the L1 (or L5) repressor. Blocks I and II possibly form the turn and helix 2 regions of the HTH motif of the repressor. Block IV in the L1 repressor is part of the most charged region encompassing amino acid residues 72-92, which flanks the putative N-terminal basic (residues 1-71) and C-terminal acidic (residues 93-183) domains of L1 repressor.

Transportation policy to facilitate the public mode use is of the foremost importance to the local governments of Metropolitan Seoul, regarding the economic and environmental consequences of the increasing use of car. Understanding the travel behaviour is essential to the establishment of proper policy to guide more people to the use of public modes instead of private. The paper reports a result of sequential analysis of individual travel behaviour in Metropolitan Seoul, using a multi-dimensional motif search technique applied to Smart Card data that integrates individuals' different public mode uses. Groups of travel patterns with similar sequential information identified distinctive travel behaviour between Seoul north and south and between metro and bus uses. Travel patterns are more bounded within north Seoul and south Seoul respectively than crossing Han River between north and south. Within north and south, travel patterns visiting northern CBD and southern CBD, respectively, as well as their local neighbour in north and south, often use metro and metro-local bus combination, while travel patterns visiting only the north and south locals without CBDs more use only the local bus line and even only the areal bus line.

To understand the molecular structure and pathogenesis mechanism of Korean garlic viruses, we have isolated cDNA clones for garlic viruses. The partial nucleotide sequences of 24 cDNA clones were determined and those of five clones containing poly(A) tail were compared with sequences of other plant viruses. One of these clones, V9, has a primary structure similar to the carlavirus group, suggesting that the clone V9 derived from a part of garlic latent virus (GLV). Northern blot analysis with the clone V9 as a probe demonstrated that GLV genome is 8.5 knt long and has a poly(A) tail. The clone V9 encodes coat protein (CP) of 33 kDa and nucleic acid binding protein of 10 kDa in different reading frame. The hexanucleotide motif, 5'-ACCUAA, which is conserved in the 3' noncoding region arid was proposed to be a cis-acting element involved in the production of negative strand genomic RNA was noticed. Complementary sequence to the hexanucleotide motif, 5'-TTAGGT, is also found in the positive strand of V9 RNA. The putative CP gene was cloned into the pRSET-A expression vector and expressed in E. coli BL21. The expressed recombinant V9CP protein was purified by $Ni^{2+}$ NTA affinity chromatography. The anti-V9CP antibody recognizes 34 kDa polypeptide which could be CP of GLV in infected garlic leaf extract. Immunoblot and Northern blot analysis of various cultivars shows wide occurrence of GLV in Korean garlic plants.

Talaromyces flavus mediates the transmission of Apple stem grooving virus (ASGV) to several host plants. The ASGV-F carried by T.flavus was partially purified from the fungus. Based on sequence analysis and homology searches, this is closely related to other ASGV strains isolated from host plants. The partially purified viral coat protein (CP) was separated on a 12% SDS-polyacrylamide gel and analyzed by Western blotting with an ASGV anti-serum. A single band at 28 kDa reacted with the ASGV anti-serum. The deduced amino acid sequence of the ORF-l showed conserved domains, including an NTP-binding helicase motif, GFAGSGKT. The amino acid sequences of the helicase and CP showed strong homology to other ASGV strains (98%). All ASGV isolated from plants and fungi had salt bridges composed of the CP and the GFAGSGKT motif of the helicase, which are commonly conserved in plant viruses. These results suggest that ASGV-F is one of ASGV strains isolated from T.flavus based on sequence similarity as well as the serological analysis of CP.

The SNF2/SW12 family comprises proteins from a variety of species with in vivo functions, such as transcriptional regulation, maintenance of chromosome stability during mitosis, and various types of DNA repair. This study was shown the characterization of hrp2+ gene which was isolated by PCR amplification using the conserved domain of SNF2 motifs. Sequence analysis of hrp2+ gene showed striking evolutionary conservation among the SNF2 family of proteins. The transcript of hrp2+ gene was found to be a 4.7 kb as identified by Northern hybridization. In addition, to determine the transcription initiation site of hrp2+ gene, primer extension analysis was performed. This result showed the band of 64 bp. The transcriptional start point was mapped to a position of 47 base pair from the first ATG codon of translational initiation codon. In order to investigate the inducibility of hrp2+ gene, transcript levels were examined after treating the cells to various DNA damaging agents. The transcripts of hrp2+ were induced by UV-irradiation. But the transcripts were not induced by treatment of 0.25% Methylmethane sulfonate (MMS). These results implied that the effects of damaging agents are complex and different regulatory pathways exist for the induction of this gene.

GATA transcription factors are widespread eukaryotic regulators whose DNA-binding domain is a class IV zinc finger motif in the form $CX_{2}CX_{17-20}CX_{2}C$followed by a basic region. In fungi, they act as transcriptional activators or repressors in several different processes, ranging from nitrogen source utilization to mating-type switching. Using an in-house bioinformatics portal system, we surveyed 50 fungal and 9 out-group genomes and identified 396 putative fungal GATA transcription factors. The proportion of GATA transcription factors within a genome varied among taxonomic lineages. Subsequent analyses of phylogenetic relationships among the fungal GATA transcription factors, as well as a study of their domain architecture and gene structure, demonstrated high degrees of conservation in type IVa and type IVb zinc finger motifs and the existence of distinctive clusters at least at the level of subphylum. The SFH1 subgroup with a 20-residue loop was newly identified, in addition to six well-defined subgroups in the subphylum Pezizomycotina. Furthermore, a novel GATA motif with a 2f-residue loop ($CX_{2}CX_{21}CX_{2}C$, designated 'zinc finger type IVc') was discovered within the phylum Basidiomycota. Our results suggest that fungal GATA factors might have undergone multiple distinct modes of evolution resulting in diversified cellular modulation in fungi.

The immune response-related genes have been suggested to be the most favorable genes for positive selection during evolution. Comparing the entire DNA sequence of chimpanzee chromosome 22 (PTR22) with human chromosome 21 (HSA21), we have identified 15 orthologs having indel in their coding sequences. Among them, interferon-${\alpha}$ receptor-1 gene (IFNAR1), an immuneresponse-related gene, is subjected to comparative genomic analysis. Chimpanzee IFNAR1 showed the same genomic structure as human IFNAR1 (11 exons and 10 introns) except the 3 bp insertion in exon 4. The sequence alignment of IFNAR1 coding sequence indicated that 'ISPP' amino acid sequence motif is highly conserved in chimpanzee and other animals including mouse and chicken. However, the human IFNAR1 shows that one proline residue is missing in the sequence motif. The homology modeling of the IFNAR1 structures suggests that the proline deletion in human IFNAR1 leads to the formation of the following ${\alpha}$-helix, whereas two sequential prolines in chimpanzee IFNAR1 inhibit it. As a result, human IFNAR1 may adopt a characteristic structure distinct from chimpanzee IFNAR1. This human specific trait could contribute to specific immune response in the most optimized manner for humans. Further molecular biological studies on the IFNAR1 will help us to gain insights into the molecular implication of species-specific host-pathogen interaction in primate evolution.

The 21st century directs designomics to achieve wealth by designing old beyond a simple recognition of the importance of culture. One of the representative local cultures of Gyeongnam is Gaya culture. The Gaya period had over 600 years history with rich and excellent iron manufacturing skill and advanced pottery culture. It is the very time to reevaluate the importance of Gaya equivalent to the Three Kingdoms in our ancient history which was has been so far ignored and isolated. In order to develop unique and excellent culture of Gaya as local fashion cutural goods, questionnaire survey on the recognition of Gaya culture and cultural goods purchasing status had been conducted to target visitors of Representative National Museum. Data Analysis Using SPSS 18.0 Win was performed with frequency analysis and t-test. As to the questionnaire survey, important criteria for purchasing in case of buying cultural goods could be found and the residents in Gyeongnam had higher recognition of developing cultural goods by the motif of Gaya relics. 'Mounted vessel in the shape of warrior on horseback(12.4%)' and 'Chariot wheel-shaped Pottery(10.8%)' were selected the most suitable motif, 'Cellphone strap(11.0%)' and 'key holder(10.2%), 'cup (7.2%)'were selected the most suitable item of cutural goods. These will be actively reflected in the development of fashion cultural goods design applying Gaya relics.

Cinnamate-4-hydroxylase (C4H) is a key enzyme of phenylpropanoid pathway, which leads a variety of secondary metabolites to participate in differentiation and protection of plant against environmental stresses. In this study, we isolated a full-length cDNA of the C4H gene from a black raspberry (Rubus occidentalis L.), using a reverse transcriptase-PCR and rapid amplification of the cDNA ends (RACE)-PCR. The full-length cDNA of the RocC4H gene contained a 1,515 bp open reading frame (ORF) encoding a 504 amino acid protein with a calculated molecular weight of about 57.9 kDa and an isoelectric point (pI) value of 9.1. The genomic DNA analysis revealed that RocC4H gene had three exons and two introns. By multiple sequence alignment, RocC4H protein was highly homologous with other plant C4Hs, and the cytochrome P450-featured motifs, such as the heme-binding domain, the T-containing binding pocket motif (AAIETT), the ERR triad, and the tetrapeptide (PPGP) hinge motif, were highly conserved. Southern blot analysis revealed that RocC4H is a single copy gene in R. occidentalis.
