The study on plane composition in clothing was focused mainly on woven wear earlier but its application has been reaching the knit wear. This study is confined to the utilization with geometrical linear pattern in the modern apparel. The work here intends to grasp the plane structure found in both woven wear and knit wear and, in particular, to understand the aesthetics of fashion. The modern flat patterned clothing has been affected by the oriental style or postmodernism in view of social and cultural aspect while its fabric material and expression method shows the diversity in terms of industrial and technical aspect. It can be characterized as several outstanding patterns: the geometrical pattern in structure, the linear pattern with seam line and 2-dimensional plane pattern without seam line, and the flexible silhouette integrated into one single shape with human body unlike the traditional apparel The aesthetics of fashion in modern flat patterned clothing can be divided into such category as the organically spatial change, the re-creation of tradition and the non-format framework. The organically spatial change shows the geometrical formation in clothes due to change in dimension, where the organically changing uniformity and generosity appears as the dimension progresses. The timeless without any difference of up and down, left and right, and inside and outside and the discontinuity due to limitless spatial change are also imbedded. The re-creation of tradition tells the reshaped spirits of old tradition by integrating and modifying the hereditary features in the old customed clothing into modern clothing. The modern flat patterned clothing implies the contemporaneousness or the frame through which the old and modern cultures may be shared and indicates the re-creation of the past and uniformity. The non-format framework contains the uncertainty in meaning and it doesn't have any certain standards. As both the apparel and the human body with this style aim at the open space, the numerous contingencies are realized.

Two kinds of cDNA encoding mouse $Gal{\beta}$1,3(4)GlcNAc ${\alpha}$2,3-sialyltransferase (mST3Gal III) and $Gal{\beta}$1,4(3)GlcNAc ${\alpha}$2,3-sialyltransferase (mST3Gal IV) were isolated from mouse brain cDNA library by means of a PCR-based approach. The cDNA sequences included an open reading frame coding for proteins of 374 and 333 amino acids, respectively, and the primary structure of these enzymes suggested a putative domain structure consisting of four regions, like that in other glycosyltransferases. The deduced amino acid sequences of mST3GaI III and IV showed a 98% and 89% identity with rat ST3GaI III and human ST3Gal IV, respectively. Northern analysis indicated that the expression of mST3Gal III mRNA was abundant in heart, liver and adult brain, while that of mST3GaI IV mRNA was detected in all tissues tested except for testis, but the level was the highest in liver. Soluble forms of mST3GaI III and IV transiently expressed in COS cells exhibited enzyme activity toward acceptor substrates containing the terminal either $Gal{\beta}$1,3GlcNAc or $Gal{\beta}$1,4GlcNAc sequences. The substrate preferences of both enzymes were stronger for tetrasaccharides than for disaccharides.

In an effort to isolate novel strains expressing a thermostable esterase that hydrolyzed the rac-ketoprofen ethyl ester to ketoprofen in the stereospecific manner, we screened various soils and composts from broad ecological niches in which the activity was expected to be found. Three hundreds of microbial strains were tested to determine their ester-hydrolyzing activity by using an agar plate containing insoluble tributyrin as an indicative substrate, and then further screened by activity on the (R,S)-ketoprofen ethyl ester. Twenty-six strains were screened primarily at high growth and incubation temperature and further compared the ability to ethyl ester-hydrolyzing activity in terms of conversion yield and chiral specificity. Consequently, a strain JYl44 was isolated as a novel strain that produced a (R)-stereospecific esterase with high stability and systematically identified as a Bacillus stearothermophilus JY144. The enzyme indeed stables at a broad range of temperature, upto 65 $^{\circ}C$, and pH ranging from 6.0 to 10.0. The optimal temperature and pH for enzymatic conversion were 50 $^{\circ}C$ and 9.0, respectively. Based on the observations that resulted a poor cell growth, and enzyme expression in wild type strain, we further attempted the gene cloning into a general host Escherichia coli and determined its primary structure, concomitantly resulting a high level expression of the enzyme. The cloned gene had an open reading frame (250 amino acids) with a calculated molecular mass of 27.4 kDa, and its primary structure showed a relative high homology (45-52 %) to the esterases from Streptomyces and Bacillus strains. The recombinant whole cell enzyme could efficiently convert the rac-ketoprofen ethyl ester to (R)-ketoprofen, with optical purity of 99 % and yield of 49 %.

Nowaday, most of the low-rise concrete structures which have less than five stories were built before the intensified seismic code was established 2005. According to the fact that our country is not a safety zone ay more, studies are need to reinforce the seismic performance of that structures. The basic frame of low-rise structure are consist of beams and columns with partition walls, therefore that are very weak about secondary wave of earthquake because of the high stiffness. The partition wall are consist of open channel for sunlight or ventilation and intermediate wall. The intermediate walls will enhance the stiffness of columns, but will cause shear failure with short column effects because of the reduced effective depth. But we don't have studies and adequate design code for partition wall effects, therefore some more studies are need for these facts.
An integrated geophysical survey was conducted to study a construction method of the Sonsanri tombs including the Muryong royal tomb. With the distribution of soil resistivity and self potential values, the boundary between original ground and the construction site was delineated clearly. The original ground has relatively high resistivity of $1,000\~1,500$ ohm-m and low self-potential values of $0{\pm}3mV/m$, while the construction site has low resistivity less than 200 ohm-m and quite high self-potential values of $-20\~30mV/m$. It is interpreted that the open site for construction of subsurface tomb has the size of about 35 m in the north-south direction. Big difference in characteristics of ground between the tomb site and the original site gives a clue for the construction method of tombs in Baekje dynasty. The site was opened about 35 meters in the north-south direction and then a mold structure was constructed with a brick frame outside. The brick frame consists of bricks cemented each other and structually combined. The mold structure was removed from inside after refill of the opened construction site with some cemented rock debris and soil.

Two types of piloti-type high-rise RC building structures having irregularity in the lower two stories were selected as prototypes, and nonlinear time history analysis was performed using OpenSees to verify the analysis technique and to investigate the seismic capacity of those buildings. One of the buildings studied had a symmetrical moment-resisting frame (BF), while the other had an infilled shear wall in only one of the exterior frames (ESW). A fiber model, consisting of concrete and reinforcing bar represented from the stress-strain relationship, was adapted and used to simulate the nonlinearity of members, and MVLEM (Multi Vertical Linear Element Model) was used to simulate the behavior of the wall. The analytical results simulate the behavior of piloti-type high-rise RC building structures well, including the stiffness and yield force of piloti stories, the rocking behavior of the upper structure and the variation of the axial stiffness of the column due to variation in loading condition. However, MVLEM has a limitation in simulating the abrupt increasing lateral stiffness of a wall, due to the torsional mode behavior of the building. The design force obtained from a nonlinear time history analysis was shown to be about $20{\sim}30%$ smaller than that obtained in the experiment. For this reason, further research is required to match the analytical results with real structures, in order to use nonlinear time history analysis in designing a piloti-type high-rise RC building.
As an art group, De Stijl (1917-1931) led a total art movement encompassing painting, sculpture, design, and architecture. Among these, architecture, as a model of the total art pursued by the group, was encapsulated by the term 'plastic architecture.' The term reflects architecture's shared features with plastic art, especially its pictorial characteristics. Firstly, De Stijl architecture shares geometric form with painting. Assembled in simple, clear and rational structures, the geometric forms signified universal forms, and extended the pictorial experimentation that Mondrian exercised through Neo-Plasticism to architecture. Constructed with colour fields made of concrete wall, De Stijl architecture is geometric abstract painting embodied in space. Together with such pictorial characteristics, large plate glass windows, narrow window frames, and cantilever structure minimize the building's visual weight. De Stijl architecture, which appears suspended in the air, is an architectural version of the abstract paintings of the era that revealed unknown spaces beyond perspective. De Stijl architecture is also an 'open' architecture, where the units placed as if radiating from the center form relations with each other flexibly and organically. The observer in such a space is encouraged to experience space within time, as his/her physical and visual mobility and extension are maximized. De Stijl architecture is an example of how the time-space continuum, represented within picture frame through Cubism, Futurism, and abstract art, can be realized in space. By transforming the ideal space of painting into real space in this way, 'plastic architecture' turned out to be an architectural manifestation of the utopianism of the era, aimed at building a society in 'perfect harmony.' However, such rationalism and universalism are not free from the violence of totalization that deletes various differences. This is evident in the history that followed as the geometric form of architecture and urban planning proliferated across the globe, engulfing the diverse natural landscapes and local cultures.
A gene, $phbC_{2.4.1}$ encoding poly-3-hydroxybutyric acid (PHB) synthase of Rhodobacter sphaeroides 2.4.1 was cloned by employing heterologous expression in Escherichia coli. R. sphaeroides chromosomal DNA partially digested with MboI was cloned in pUC19 followed by mobilization into E. coli harbouring $phbA,B_{AC}$ in pRK415, which code for ${\beta}$-ketothiolase and acetoacetyl CoA reductase of Alcaligenes eutrophus, respectively. Two E. coli clones carrying R. sphaeroides chromosomal fragment of $phbC_{2.4.1}$ in pUC19 were selected from ca. 10,000 colonies. The PHB-producing colonies had an opaque white appearance due to the intracellular accumulation of PHB. The structure of PHB produced by the recombinant E. coli as well as from R. sphaeroides 2.4.1 was confirmed by [$H^{+}$]-nuclear magnetic resonance (NMR) spectroscopy. Restriction analysis of the two pUC19 clones revealed that one insert DNA fragment is contained as a part of the other cloned fragment. An open reading frame of 601 amino acids of $phbC_{2.4.1}$ with approximate M.W. of 66 kDa was found from nucleotide sequence determination of the 2.8-kb SaiI-PstI restriction endonuclease fragment which had been narrowed down to support PHB synthesis through heterologous expression in the E. coli harbouring $phbA,B_{AC}$. The promoter (s) of the $phbC_{2.4.1}$ were localized within a 340-bp DNA region upstream of the $phbC_{2.4.1}$ start codon according to heterologous expression analysis.

Pseudomonas sp. S-47 is a bacterium capable of degrading benzoate as well as 4-chlorobenzoate (4CBA). Benzoate and 4CBA are known to be degraded via a meta-cleavage pathway characterized by a series of enzymes encoded by xyl genes. The meta-cleavage pathway operon in Pseudomonas sp. S-47 encodes a set of enzymes which transform benzoate and 4CBA into TCA cycle intermediates via the meta-cleavage of (4-chloro )catechol to produce pyruvate and acetyl-CoA. In the current study, the meta-pathway gene cluster was cloned from the chromosomal DNA of S-47 strain to obtain pCS1, which included the degradation activities for 4CBA and catechol. The genetic organization of the operon was then examined by cloning the meta-pathway genes into a pBluescript SKII(+) vector. As such, the meta-pathway operon from Pseudomonas sp. S-47 was found to contain 13 genes in the order of xylXYZLTEGFlQKIH. The two regulatory genes, xylS and xylR, that control the expression of the meta-pathway operon, were located adjacently downstream of the meta-pathway operon. The xyl genes from strain S-47 exhibited a high nucleoside sequence homology to those from Pseudomonas putida mt-2, except for the xylJQK genes, which were more homologous to the corresponding three genes from P. stutzeri AN10. One open reading frame was found between the xylH and xylS genes, which may playa role of a transposase. Accordingly, the current results suggest that the xyl gene cluster in Pseudomonas sp. S-47 responsible for the complete degradation of benzoate was recombined with the corresponding genes from P. putida mt-2 and P. stutzeri AN10.

Visual features of a mushroom(Lentinus Edodes L) are critical in sorting and grading as most agricultural products are. Because of its complex and various visual features, grading and sorting of mushrooms have been done manually by the human expert. Though actions involved in human grading looks simple, a decision making undereath the simple action comes form the results of the complex neural processing of the visual image. And processing details involved in the visual recognition of the human brain has not been fully investigated yet. Recently, however, an artificial neural network has drawn a great attention because of its functional capability as a partial substitute of the human brain. Since most agricultural products are not uniquely defined in its physical properties and do not have a well defined job structure, a research of the neuro-net based human like information processing toward the agricultural product and processing are widely open and promising. In this pape , neuro-net based grading and sorting system was developed for a mushroom . A computer vision system was utilized for extracting and quantifying the qualitative visual features of sampled mushrooms. The extracted visual features and their corresponding grades were used as input/output pairs for training the neural network and the trained results of the network were presented . The computer vision system used is composed of the IBM PC compatible 386DX, ITEX PFG frame grabber, B/W CCD camera , VGA color graphic monitor , and image output RGB monitor.
