Recent identification and characterization of plant homeobox genes suggest that they play important roles in morphogenetic events. OSH1, one of the rice homeobox genes, is thought to be related to organ development since the changes of OSH1 gene expression cause morphological abnormalities of leaves by the ectopic expression and is expressed during early embryogenesis. In this experiment, the expression pattern of OSH1 was analyzedinmutants by in situ hybridization, and OSH1's potential as a molecular marker was explored. Region-specific expression of OSH1 during early embryogenesis shows that OSH1 could be used as a molecular marker for characterizing embryo mutants. Although several organless and shootless mutants showed normal expression of OSM1, some mutants exhibited abnormal expression patterns. In a minute organless cle1-1 embryo whose epidermis resembled morphologically the epithelium of scutellum, OSH1 expression was limited to a small basal region. This expression pattern suggests the gross deletion of the basal part. In a radicleless mutant, odm115, OSH1 expression was detected in a basal region instead of subcentral region of the ventral side. Together with other characteristics (short embryo and normal adventitious roots), odm115 was estimated to be derived from the deletion of basal region. Among five shootless mutants, three showed normal expression of OSH1. In the shl2 embryo, no expression of OSH1 was observed. In the shl1 embryo, however, OSH1 expression was extended to a dorsal side, indicating that SHL2 might be related to dorsoventral patterning. The above results of in situ hybrydization clearly indicate that OSH1 can be utilized as a marker for characterizing gene functions of embryo mutants.

Background: BRCA1-associated protein 1 (BAP1) mutations are frequently reported in clear cell renal cell carcinoma (ccRCC); however, very few studies have evaluated the role of these mutations in other renal cell carcinoma (RCC) subtypes. Therefore, we analyzed BAP1 protein expression using immunohistochemistry in several RCC subtypes and assessed its relationship with clinicopathological characteristics of patients. Methods: BAP1 expression was immunohistochemically evaluated in tissue microarray blocks constructed from 371 samples of RCC collected from two medical institutions. BAP1 expression was evaluated based on the extent of nuclear staining in tumor cells, and no expression or expression in <10% of tumor cells was defined as negative. Results: Loss of BAP1 expression was observed in ccRCC (56/300, 18.7%), chromophobe RCC (6/26, 23.1%), and clear cell papillary RCC (1/4, 25%), while we failed to detect BAP1 expression loss in papillary RCC, acquired cystic disease-associated RCC, or collecting duct carcinoma. In ccRCC, loss of BAP1 expression was significantly associated with high World Health Organization (WHO)/International Society of Urological Pathology (ISUP) grade (p=.002); however, no significant correlation was observed between loss of BAP1 expression and survival in ccRCC. Loss of BAP1 expression showed no association with prognostic factors in chromophobe RCC. Conclusions: Loss of BAP1 nuclear expression was observed in both ccRCC and chromophobe RCC. In addition, BAP1 expression loss was associated with poor prognostic factors such as high WHO/ISUP grade in ccRCC.

The purpose of this study is to analyze expression of pluralism in contemporary fashion. This study has three parts. They are to understand the concept of pluralism, to find the fashion environments of pluralism in terms of politics, economics, sociality, culture, science, and art, and to analyze expression of pluralism in contemporary fashion. The concept of pluralism in contemporary fashion is the diversity and compounds of fashion images. The environments of pluralism in contemporary fashion are multinational economic system, virtual world of internet. mass-culture and postmodern art. And expression of pluralism in contemporary fashion is analyzed into publicity. Publicity is expressed by using things of common lifestyle and the past that people used to and are well-known. Horizontality is expressed by coordination of male-female facts and property-poorness without high or low concept. Multi-nation is expressed by mixing various kind of national characteristics and Virtuality is expressed by layering and collaging complex facts that are not connected each other.

Three types of sludges including printing paper, newsprint and tissue paper were prepared at 5% concentration for filtration-expression operations. Filtration-expression characteristics of sludge were measured in different pressure and wastepaper powder dosage. Specific filtration resistance and porosity were calculated with theoretical formula. Higher pressure increased the progresses of filtration and expression while it decreased porosity. The addition of 5% wastepaper powder more accelerated the progresses of filtration and expression than that of 10% wastepaper powder. The lowest porosity value was also measured at 5% dosage of wastepaper powder. The decrease of porosity implied the decrease of moisture content in cake. The results indicated that dewatering of sludge was efficient in high pressure and 5% dosage of wastepaper powder.

Gene expression profiling facilitates the understanding of biological characteristics of gliomas. Previous studies mainly used regression/variance analysis without considering various background biological and environmental factors. The aim of this study was to investigate gene expression differences between grade III and IV gliomas through partial least squares (PLS) based analysis. The expression data set was from the Gene Expression Omnibus database. PLS based analysis was performed with the R statistical software. A total of 1,378 differentially expressed genes were identified. Survival analysis identified four pathways, including Prion diseases, colorectal cancer, CAMs, and PI3K-Akt signaling, which may be related with the prognosis of the patients. Network analysis identified two hub genes, ELAVL1 and FN1, which have been reported to be related with glioma previously. Our results provide new understanding of glioma pathogenesis and prognosis with the hope to offer theoretical support for future therapeutic studies.

This paper discusses a Korean-English machine translation method using expression patterns. The expression patterns are defined for the purpose of aligning Korean expressions with appropriate English expressions in semantic and expressive senses. This paper also argues to develop a new Korean syntax analysis method using agglutinative characteristics of Korean language, expression pattern concept, sentence partition concept, and incorporation of semantic structures as well in the parsing process. We defined a simple Korean grammar to show the possibility of new Korean syntax analysis method.

The purpose of this study is to analyze the aesthetic characteristics of 'movement' expression in modern fashion(1910-2004) based on a study of modern fine arts which adopted 'movement' element in their work. In this study the meaning of movement was defined as motion, changing position and transformation. Literature survey through books and research papers and demonstrative study with fashion collection photos were undertaken. The results wert as follows ; 1) Kinetic art, optical an, light kinetic art and technology art such as video and computer art have adopted 'movement' element in their work. 2) The plasticities of 'movement' fine arts were identified as mutual penetration, increase of visibility, use of non-traditional materials and dynamism. The internal meanings were identified as expansion of aesthetic experience and the concept of fine art, optimistic attitude on technology, spectator participation and integration of art and life. 3) The 'movement' expression in modern fashion was distinctively found in 1910s-20s(avant-garde fashion), 1960s (kinetic and optical art fashion) and mid 1990s to 2004 (techno-cyber fashion). 4) The plasticities of the 'movement' expression in modern fashion were identified as non-definition, use of non-traditional materials, dynamism. The internal meanings were identified as expansion of aesthetic experience and the concept of dress, optimistic attitude on technology, playfulness through participation. In conclusion, the expression of 'movement' in modern fashion has optimistic viewpoint on the development of modern society and is one of the interesting design points which will be pursued in the fellowing years.

The promoters of a variety of plant genes are characterized by the presence of TGACG motif-containing sequences. These genes often exhibit quite diverse expression characteristics and in many case the TGACG-motif has been demonstrated to be essential for expression. Here we report the isolation and characterization of a soybean cDNA that encodes a novel basic/leucine zipper (bZIP) protein, STF1, that specifically interacts with Hex (TGACGTGG) and CRE (TGACGTCA) sequences. This protein contains a bZIP motif at C-teminus and an acidic domain at N-terminus. DNA binding specificities, heterodimer formation, and expression characteristics of STF1 were compared with a soybean TGA1 protein, STGA1. The soybean STF1 interacts with TGACG-sequences containing an ACGT core, while STGA1 requires TGACG as a sufficient binding sequence. The flanking sequences to the TGACG motif affected DNA binding of STF1 siginificantly. The STF1 mRNA is found mainly in dark grown soybean seedling with higher expression in apical and elongating hypocotyl, while STGA1 mRNA is highly abundant in roots of light grown plants. Furthermore, we demonstrate that STF1 heterodimerzes with G-box binding factorss (GBFs) which was not observed with TGA1. The fact that STF1 possesses both distinct DNA binding speficities and heterodimerization properties suggest that STF1 belongs to a new family of plant bZIP proteins which recognize the Hex/CRE motif.

This study analyzed expression types and characteristics of modern fashion designs using body parts. The research was conducted based on a literature review and empirical research of fashion magazines published in Korea and other countries from 2001 to 2008. Four fashion statements predominated. Most frequently, body parts presented in modern fashion design, included realistic expressions, simplification, anatomic expression and a mixture with other patterns and logos. A body part, such as an eye, a lip, a hand or a chest was characteristically located in an unfamiliar position, as part of modern fashion design using body parts. Other parts and surrealistic images were shown with accessories utilizing body shapes. Second, amusing images were emphasized with humorous expressions, including simplification of body parts, childish decorations, fairy tale illusions and cartoon factors. Third, erotic images were presented with a more realistic expression of a partial image of a female body part, such as a lip or a tongue. Fourth, the use of facial images of celebrities in modern fashion design showed the phase of the times and the characteristic utilization of pop art as an image.

Handbags are a part of fashion and while their significance and value are increasing, research on this topic is lacking. This study defines handbags and categorizes the materials used for making handbags, sewing methods, expression techniques, and terminologies related to accessories. A total of 1,743 handbags that were released from the Spring 2020 to Fall 2023, Ready-to-Wear collections by 8 selected brands (Hermes, Dior, Fendi, Chanel, Louis Vuitton, Prada, Gucci, and Alexander McQueen), were analyzed. Out of these, 732 unique designs, excluding those with only color variations, were studied. The most common sewing methods were 'Cut, sewing, and edge painting', 'Cylinder arm sewing', 'Cut, edge painting, and sewing', and 'Inverted seam', in that order. Slim strap designs primarily used the 'Cut, sewing, and edge painting' method, whereas the body, especially with narrow and hard leather, was best suited for the 'Cylinder arm sewing machine'. For expression techniques, the most frequently used methods were 'Quilting', 'Metal Eyelet', 'Embossing', 'Printing', 'Punching', and 'Weaving', respectively. The characteristics of each brand's production methods, expression techniques, and accessories were as follows: First, the exposure of logos and monograms is prominent. Unlike clothing, handbags often prominently feature the brand's logo or monogram. Second, signature quilting is a prominent feature. Quilting effectively conveys the brand's signature style, providing cushioning, volume, and pattern effects. Third, sustainable development is a growing trend. Brands are increasingly applying eco-friendly and socially responsible designs.
