This study investigates the characteristics of Nordic sweaters works from a historical perspective. Specifically, this study deals with the following research topics: 1) development of Nordic sweaters, 2) the characteristics of Nordic sweaters industry according to the change of times, 3) the comparison of local knitting patterns, 4) the symbolic meaning of the designs in the Nordic sweaters and patterns. The results of the study are summarized as follows. 1. Knitted work developed mostly in Northern Europe, a cold area, and the barren, mountainous coastal areas where people frequently used woolen materials for clothes. It was also developed in Scandinavian regions which lead the fashion in modern days. Scandinavian knitting techniques have been diffused into the east coast of England and Northern Europe by Vikings. 2. Scandinavian countries are distinguished from other countries by their conservative but creative cultural tradition. Their knitting patterns are characterized by small geometric figures such as dots, triangles, squares, rhombuses, and crosses used often with stars and roses. Scandinavian knitting is also salient for its vertical stripes and simple motifs repeating at short intervals. 1) Norway ; Simple and geometric Norwegian patterns are classified into three groups of motifs: (a) the motifs of cross, diamond, X, and swastika (equation omitted). (b) the motifs of human figures, animals and birds, (c) floral motifs (especially eight-petal roses). Their use of color is also simple, and is limited to more than two colors. (2) Sweden ; Swedish patterns are colorful and geometric. They are characterized by features such as brocade, complex embroidery, and contrast of red and black colors. They also show Guernsey patterns. Initials and production years were knitted in sweaters which have different patterns in their trunks and sleeves. 3) Denmark ; The Danish pattern is the purl stitch knitted against the stockinette stitch. The technique is used to copy woven damask motifs. The patterns are seen most clearly when they are knit with smooth yarn. The Faeroe sweaters are the representative work of Danish knitting. Faeroe knitting, incorporates stranded pattern and is knit in the round, either with circular needles. 4) Finland ; Finnish patterns are similar to Norwegian patterns. Finnish knitted work show very colorful, variety and free-flowing geometric patterns. 5) Iceland ; Icelandic knitting shows original ribbon pattern. Lope sweater is the representative work. 3. The traditional knitting patterns not only carried symbolic meanings but also served as means of communication. First of all, patterns had incantatory meanings. Patterns were symbolic of one's social standing, too. The colors, motifs and their arrangements were very important features symbolizing one's social position or family line. People often communicated by certain pieces of knitted work or patterns. In short, the knitted work in the Nordic sweaters served the function of admiring the beauty of nature and symbolizing various meanings. The unique designs and colors of the knitted work reflected the characteristics of the culture those works belonged to. This study also turns our attention to the issue of how the traditional colors and designs of the knitted work can contribute to the development of modern designs, and by doing so, if makes us realize the importance of knitted works in modern society.

Current information-oriented society is expanding rapidly with the huge change to our society from the information revolution emerged in mid '50s. Information technique such as computer, communication satellite and cable technology play their in this information-oriented society, and in 1980s, digital technique was adopted to media, inviting new phenomenon in communication of overall society. Expectations and hope for new trends and changes from digital era flourished when we entered into new Millenium, the 21st century. Since then we have gone through changes in years from analogue to digital. Now the word 'digital' is conceived in unified manner in almost every fields and influences overall society, changing our life pattern rapidly. Modern society had demanded some speedy and bidirectional communication tool in shifting digital era, and resulted from that was a new culture, Now the society changes more and more quickly under the speedy information sharing. From that perspective we need to establish the aspects of sensibility expression, which is one feature of the communication. The sensibility-oriented digital was originated from the human nature, which counts emotion and composure much. To satisfy the human nature a new cultural value which transcend a traditional one is needed. And the sensitivity expression to meet the need is one communication tendency in digital era. Digital era has totally different social qualities from that of analogue era. In digital era, prompt respond to rapid change and creativity combined with sensitivity are needed. Therefore a man with sensitivity would be more outstanding than a man of intelligence. The picture of digital and analogue in our society consists of two axis one is analogue axis like retrospective trend, admiration for nature , oriental thought etc. , and the other is the digital axis of internet and information technology. Sensibility can be widely interpreted as analogue thinking. It is surely different from the plain retrospective trend or nostalgia for past. It is a tendency that digital technology is used and cooperated with the emotion in human nature, In this paper we suggest the sensitivity expressions in detail through the study cases including both sides of digital and sensitivity expressions such as 'Bravo your life' advertising campaign of Samsung Insurance, MP3 advertising campaign, and 'Mini-homepage' of Cyworld. Under the circumstances the main direction of communication is oriented to human. This study's purpose is to think the true meaning of this digital era, to overcoming its weaknesses, such as over-dependency on technique and selfish individualism and to harmonize digital and sensitivity expression. The sensitivity-oriented expression than the reason-oriented one is expected to be put forth in whole media, and this is a more efficient tendency under the shifting digital era.

일반적으로 체세포배를 경유한 대량증식은 증식효율이 높다. 그러나 종종 배수성 변이와 같은 체세포 변이를 야기하기도 한다. 본 연구에서는 Doritaenopsis hybrid의 체세포배 증식시 발생하는 배수성 변이체와 체세포배의 세포에 내재되어 있는 내배수화된 세포와의 관계를 구명하여 배수성 변이체 발생 원인을 밝히고자 실시되었다. 내배수성 분석결과 체세포배의 상부는 $2C{\sim}16C$의 DNA를 함유한 세포들로 구성되어 있는 반면, 중부와 하부 조직에는 $2C{\sim}32C$의 내배수성이 높은 세포들이 내재되어 있었다. 또한 체세포배 연령별로는 2주된 체세포배가 $2C{\sim}16C$ 정도의 세포로 구성되어 있는 반면 10주령의 체세포배는 $2C{\sim}64C$까지 고도로 내배수화가 진행된 세포들이 존재하였다. 이는 한 식물체에서도 부위, 연령에 따라 내배수성이 다를 수 있음을 보여주는 결과이다. 체세포배 부위중 내배수성이 낮은 상부와 높은 하부로 절단하여 각각의 절편체를 배양한 결과 배수성 변이체의 발생은 내배수성이 높은 하부를 배양하였을 때 3배 이상 높았다. 본 연구결과는 변수성 변이체의 발생원인이 내배수화된 세포에 있음을 보여주며 이를 기초로 Dtps. hybrid의 안정적인 증식체계를 구축하는데 기초가 되리라 생각된다.

8세부터 17세까지 4회의 세균성 뇌수막염을 경험하였던 21세 남자에서 세균성 뇌수막염이 재발하였고, 혈액과 뇌척수액에서 group B streptococcus (GBS)가 배양되었다. GBS에 의한 성인 뇌수막염의 사례는 흔하지 않으며, 본 증례 환자의 경우에도 과거 소아청소년시기에 재발했던 뇌수막염의 원인은 Streptococcus pneumoniae였다. 저자들은 세균성 뇌수막염이 재발하는 원인 중 환자의 면역 결핍 여부에 대해서는 검사를 통해 배제하였고, 기존의 여러 연구결과에 비추어보아 첫 발병 시부터 존재했던 두개저 해부학적 이상이 S. pneumoniae에 의한 뇌수막염 재발의 원인이라고 판단하였다. 나아가 성인이 되어 GBS 뇌수막염이 발병한 이유는 GBS 혈청형에 대한 옵소닌 포식항체의 혈청학적 유병률을 조사한 연구에 비추어보아 증례 환자가 GBS Ib에 대한 항체가 음성인 경우라면, 해부학적 결함이 해결되지 않은 상태가 코인두 보균이 침습 감염을 일으킬 수 있는 경로가 되어 발병한 사례라고 생각하였다. 환자는 3주 간 항생제 치료 후 임상 경과가 호전되어 퇴원 후 다른 병원에서 수막종과 동반된 뇌기저부의 뇌척수액 누출을 확진 받고 수술을 받았다. 환자는 앞으로도 세균성 뇌수막염 재발 여부와 후유증으로 치료받고 있는 뇌전증에 대해 지속적인 추적관찰이 필요하다.

Bacillus polyfermenticus KJS-2 (B. polyfermenticus KJS-2)를 이용하여 발효된 콩(BP2FS)은 8가지의 병원성균에 대해 항균활성을 가졌다. BP2FS는 돌돔의 배양에 있어 사료첨가제로 사용되었다. 돌돔의 배양시 BP2FS를 투여한 군($6{\times}10^{4}$ cfu $g^{-1}$ 사료)과 투여하지 않은 군으로 나누었으며, 투여한 군은 120일 동안 하루에 두 번씩 투여 하였다. 120일 후에 투여한 군의 돌돔의 몸무게는 67.29${\pm}$12.62 g이었으며 그렇지 않은 군의 몸무게는 56.56${\pm}$8.21 g으로 나타났다. 생존율은 투여한 군(80%)과 투여하지 않은 군(40%)이었다. 폐사한 돌돔의 축적된 양은 투여한 군(18.95%)과 투여하지 않은 군(60.98%)이었다. BP2FS를 투여한 군에서 B. polyfermenticus KJS-2를 돌돔의 장내에서 검출한 결과 $1.04{\times}10^{4}$ cfu $g^{-1}$으로 나타났다. BP2FS를 투여 하지 않은 군의 돌돔에서는 iridovirus에 감염되었을 경우 나타나는 전형적인 증상인 비장과 간에서 비대세포가 관찰 되었다. 이 결과들은 BP2FS는 돌돔의 이리도바이러스에 대한 감염 시 예방효과를 가져온다 할 수 있다.

Superoxide dismutase (SOD) is physiologically important in regulating cellular homeostasis and apoptotic cell death, and its mutations are the cause of familial amyotrophic lateral sclerosis (FALS). Mitochondrial serine protease HtrA2 has a pro-apoptotic function and has known to be associated with neurodegenerative disorders. To investigate the relationship between genes associated with apoptotic cell death, such as HtrA2 and SOD1, we utilized the pGEX expression system to develop a simple and rapid method for purifying wild-type and ALS-associated mutant SOD1 proteins in a suitable form for biochemical studies. We purified SOD1 and SOD1 (G93A) proteins to approximately 90% purity with relatively high yields (3 mg per liter of culture). Consistent with the result in mammalian cells, SOD1 (G93A) was more insoluble than wild-type SOD1 in E. coli, indicating that research on the aggregate formation of SOD1 may be possible using this pGEX expression system in E. coli. We investigated the HtrA2 serine protease activity on SOD1 to assess the relationship between two proteins. Not only wild-type SOD1 but also ALS-associated mutant SOD1 (G93A) were cleaved by HtrA2, resulting in the production of the 19 kDa and 21 kDa fragments that were specific for anti-SOD1 antibody. Using protein gel electrophoresis and immunoblot assay, we compared the relative molecular masses of thrombin-cleaved GST-SOD1 and HtrA2-cleaved SOD1 fragments and can predict that the HtrA2-cleavage sites within SOD1 are the peptide bonds between leucine 9-lysine 10 (L9-K10) and glutamine 23-lysine 24 (Q23-K24). Our study indicates that SOD1 is one of the substrate for HtrA2, suggesting that both HtrA2 and SOD1 may be important for modulating the HtrA2-SOD1-mediated apopotic cell death that is associated with the pathogenesis of neurodegenerative disorder.

The purpose of this study is to analyze four separate elements-sublime beauty, elegant beauty, mysticism, ornament-which appeared in materials, patterns, colors, silhouettes, details, and accessories, laying stress on luxurious, brilliant, mysterious feelings on Gorgeous Images appeared as trend theme of modern fashion by mixing religious mysticism of the Byzantine Empire. Mysticism element is using the effect of splendid and gorgeous colors from the Orient rather than forms. And a philosophy of abundant colors in mosaics, which are seen in art forms such as architecture, paintings, etc., shows that it creates some visual rooms for religious spirits. Influenced by the fashion of the Greco-Roman style, the elegant beauty element is expressing abundant comfort and elegant feminine lines that are from creases, and it is also emphasizing natural beauty which seems to slip down by displaying the splendid images of Gorgeous as drapes that fit a body. Ornament element was reflecting an inspiration from the splendid and brilliant culture of religion in the Byzantine Age. Therefore, it was appeared as a style filling the whole with bulky silks, splendid ornamental materials embroidered in gold or silver thread, the complicated geometric patterns that are two-dimensional and dignified, and so on. It was decorated with crosses which represent Christianity as a motif, and also it emphasized the splendor of the Byzantine and dazzling splendid images of Gorgeous by using accessaries decorated with various jewels. The elements of sublime beauty are showing the beauty adding humble and majestic images to it as designs sought by spiritual values or intrinsic values. Those designs, so to speak, have pretense which does not allow to expose a body and plain pure feeling, so that they are showing some abstinent styles in a solemn atmosphere, with most details removed. We can say the Fashion Theme appearing in Modern Times is the result from representing by combining various factors of the times with formative beauty through creative works for aesthetic expression. The moderners are requiring new designs which is possible to meet their individualities, in addition to their outstanding fashion senses. From this point of view, a variety of textiles, patterns, and colors in the Byzantine have a great meaning to fulfill people's various desires as interesting elements.
