  • Recent studies in molecular biology and proteomics have identified a significant number of novel diagnostic, prognostic, and therapeutic disease markers. However, validation of these markers in clinical specimens with traditional histopathological techniques involves low throughput and is time consuming and labor intensive. Tissue microarrays (TMAs) offer a means of combining tens to hundreds of specimens of tissue onto a single slide for simultaneous analysis. This capability is particularly pertinent in the field of cancer for target verification of data obtained from cDNA micro arrays and protein expression profiling of tissues, as well as in epidemiology-based investigations using histochemical/immunohistochemical staining or in situ hybridization. In combination with automated image analysis, TMA technology can be used in the global cellular network analysis of tissues. In particular, this potential has generated much excitement in cardiovascular disease research. The following review discusses recent advances in the construction and application of TMAs and the opportunity for developing novel, highly sensitive diagnostic tools for the early detection of cardiovascular disease.

  • Ginsing polysaccharide, known to have an immune regulating effect, was administered to 23 randomly selected healthy male subjects with a mean age of 23 years in accordance with an IRB approval. Then, these subjects underwent physico-chemical tests and serum proteome was analyzed from the blood sample taken from these subjects. Analyses of proteome involved image analysis, protein sections and protein identification in sequence after two-dimensional electrophoresis was carried out. During the physico-chemical test, 4 subjects were excluded from the study. In the proteome analysis, identified were 5 spots such as SP40, 40, Cytokeratin 9, hypothetical protein LOC544932, Apolipoprotein E ,similar to Human albumin, which showed differences in the amount of protein expression. In conclusion, changes of 5 proteins were remarkable before and after administration of ginsing polysaccharides. In certain cases, hepatic and renal slight injury occurred. Thus, further clinical study on dosage regimen would be necessary for securing the basis for concentration-dependent effectiveness and safety.

  • Objectives : This study aimed at evaluation of the effects of Gastrodiae Rhizoma on brain edema and aquaporin water channel expressions in the brain. Methods : Brain edema following intracerebral hemorrhage (ICH) was induced by the stereotaxic intrastriatal injection of bacterial collagenase type VII in Sprague-Dawley rats. Then ethanol extract of Gastrodiae rhizoma was treated once a day for 3 days. Brain edema % and water contents, and cell size of neurons in the cerebral cortex were examined. Immuno-histochemistry was processed for AQP4, AQP1, and AQP9 expressions in the brain sections and area % of immuno-labeling was analyzed with image analysis. Results : 1. Ethanol extract of Gastrodiae Rhizoma reduced brain edema of ICH induced rats significantly. 2. Ethanol extract of Gastrodiae Rhizoma reduced excessive brain tissue water contents of ICH induced rats significantly. 3. Ethanol extract of Gastrodiae Rhizoma reduced cellular edema of neurons in cerebral cortex of ICH induced rats significantly. 4. Ethanol extract of Gastrodiae Rhizoma reduced AQP4 immuno-positive area % in cerebral cortex and external capsule of ICH induced rat brain significantly. 5. Ethanol extract of Gastrodiae Rhizoma reduced AQP9 immuno-positive area % in glia limitans externa of ICH induced rat brain significantly. Conclusions : These results suggest that Gastrodiae Rhizoma reveals protective effects against brain edema and cytotoxic edema of neurons by means of down-regulation of AQP4 expression in the brain.

  • Digital media technology has power of influence as extended in not only science and technology but also our society and culture. These phenomenon is explained as 'digital convergence'. Edmond Couchot argue the term 'hybridization'. Yvonne Spielmann and Jay David Bolter also argue that digital hybrid artworks across and integrates a diverse range of modes of representation, such as image, text, sound, space and bodily modes of expression. They must also address communicative interaction in the convergence of real and virtual spaces. In this paper, I noticed mixed reality environment which is seen as the form of hybrid between real and virtual object. And I discuss about this phenomenon as the study of interdisciplinary between art and science.

  • As the security system using facial recognition, the recognition performance depends on the environments (e. g. face expression, hair style, age and make-up etc.) For the revision of easily changeable environment, it's generally used to set up the threshold, replace the face image which covers the threshold into images already registered, and update the face images additionally. However, this usage has the weakness of inaccuracy matching results or can easily active by analogous face images. So, we propose the genetic algorithm which absorbs greatly the facial similarity degree and the recognition target variety, and has excellence studying capacity to avoid registering inaccuracy. We experimented variable and similar face images (each 30 face images per one, total 300 images) and performed inherent face images based on ingredient analysis as face recognition technique. The proposed method resulted in not only the recognition improvement of a dominant gene but also decreasing the reaction rate to a recessive gene.

  • The purpose of this study is to examine the design characteristic of the facade of the main adminstration building in university. The main administration building which is a basic of educational facilities has various administration setups, such as the register's office, the student affairs section, the planing department, the general affair's office and so on. This building performs academic, administration, facilities management, and admissions service. Also, the building has an ideological, historical, and symbolic image, having an organic relationships with the other educational facilities. This study choose one hundred seven universities, except universities that does not provide information easily and the second campus which does not have the main administration building, as the subjects of the study. The analysis is derived from the design elements applied to facade design of the main administration building and this is divided into design principles(balance symmetry, contrast, rhythm), the formal composition(geometrical, linear), and the style of architecture(classical architecture and modern architecture). The results of the research are summarized as follows: The design characteristic of the facade of the main adminstration building in university has chronologically changed. First of all, in the 1940's, symmetry emphasized on the center of building, superimposition, division, pediment, and arch were marked. Then, superimposition was prominent in the 1950's and symmetry emphasized on the center of building was shown in the 1960s again. Flat roof was in the 1970's, 1990s and 2000's. Finally, pediment was dominant in the 1980's. The design elements of the main administration building can be samples of chronological styles of architecture. Facade design, with proper design of the past and recent times, includes the meaning that achieve the great purpose of the university by emphasizing visual images.

  • This research is an in-depth study on the differences of cosmetics advertising and brand representation between Korean companies and Chinese companies. In addition, it studies the preferences of cosmetics consumption in Korea and China. To study these topics, two major methods are applied to magazine advertising analysis and consumer research. Analysis objects are the magazine advertisements of the Korean brands Mamond and Laneige, which entered the China market more than 5 years ago; the 64 advertisements are evenly split between Koreans and Chinese. The objects of the survey are 470 females between the ages 20 and 30 (237 from Korea and 233 from China). The results were as follows. First, Chinese advertisements use intense appeal in which the types of advertisement appeal are highly preferred. Second, ordinary models are highly preferred. Second, (on the nationality of the models) Chinese and Korean models are preferred in comparison to western models. Third, (as shown in the survey) Koreans and Chinese preferred magazine advertisements with headlines and copies. Four, blue colors are commonly used in the advertisements; however, the survey shows that the Chinese consumers prefer gray colors. Furthermore, from this study, there is a significant dynamic between the brand image and consumer satisfaction as well as the re-purchase intention.

  • Metro-Sexual is one of the most representing case showing contemporary life style of men that rooted into public already. The fundamental feature of this Metro-Sexual is the conversion of men's costume style to womanness which also could be seen from the history of clothes. The former works about sexual image, expression of sexual identity, androgynous and borderless phenomenon have been referred as base of this work. To analyze Metro-Sexual in modern social/cultural factors through such existing works will be critical part of understanding entire fashion trend in this day beyond sexual limit. As research method, former works, references, various fashion magazines and fashion related sites was used to grasp conception and womanity of Metro-Sexual. In a limited time interval from $2001{\sim}2006$ for practical work, silhouette, detail, trimming, colors, items, patterns and accessories were analyzed selected from famous S/S, F/W men's fashion collection magazine and internet site of professional fashion institute. It is obvious that Metro-Sexual already spread out in men's fashion based on such social/cultural background as new century's icon that regarded as critical factor in researching contemporary men's fashion and of the future.

  • The findings of this study indicate that intangible cultural properties are worth preservation and transmission and should be considered as very important as tangible cultural properties. If the studies of intangible cultural properties are continued focusing on their characteristics and formational system, they can be expressed more properly by adding new interactive elements to database and expressive requisites. New techniques introduced in this study are believed to provide people with most reasonable and developmental motives for expression of the existing intangible cultural properties. Concerning Korea's cultural properties centered on intangible cultural properties, information construction should be made with a new idea of information based on database from the previous studies. The result will be able to set an important factor to give wide publicity to our cultural identity, which is currently shown in the process of background communication, and serve as a foothold to deliver exact information to our descendants. The intangible cultural properties are our people's mental cultural heritage resources. If museums or initiator groups, which are organized to spread cultural heritages, can use them as the subjects of exhibition through information construction and visualization, it will function to maximize the educational effect of transmitting our national mental world. The development of digital environment will provide the optimum conditions and tools making it possible to visualize intangible forms and ideas in a virtual cyber space. Given these viewpoints, steady studies and efforts for the improvement of Korea's cultural image should be made in the way of intangible cultural properties as well as tangible ones. They start from the country's accurate appreciation of cultural properties and are embodied in systematic adjustment and relationship between interdependent elements.

  • The aim of this study was to investigate protein profiles related to the induction of adipogenesis within the bovine longissimus dorsi muscle (BLDM) by proteomic analysis. We analyzed BLDM proteins at different growth stages to clarify the physiological mechanisms of marbled muscle development in 20 head of Korean native cattle (11 month: 10 head, 17 month: 10 head). BLDM proteins were analyzed by two-dimensional electrophoresis and image analysis. Villin 2 was specifically identified by mass spectrometry and a protein search engine. Villin 2 protein expression in BLDM decreased during the fat development stage in test steers. In a Western blot cell culture study of spontaneously immortal bovine muscle fibroblasts, the abundance of Villin 2 was shown to be down-regulated during differentiation into muscle. In 3T3-L1 mouse embryonic fibroblasts, Villin 2 was decreased during differentiation into adipocytes. The results suggest that Villin 2 may be related to the induction of transdifferentiation and adipogenesis in bovine longissimus dorsi muscle.
