  • In 2009, a systemic megalocytivirus infection associated with high mortality was detected for the first time in cultured starry flounder Platichthys stellatus in Korea. Diseased starry flounder had pale bodies and gill coloring and enlarged spleens. Histopathological examinations revealed basophilic enlarged cells in various organs of diseased starry flounder. Polymerase chain reaction (PCR) was performed on tissue samples using three published primer sets developed for the red sea bream iridovirus. PCR products were detected for all primer sets, except 1-F/1-R, which are registered by the World Organization for Animal Health (OIE). The part of the gene corresponding to the full open reading frame encoding the viral major capsid protein (MCP) was amplified by PCR. PCR products of approximately 1,581 bp were cloned, and the nucleotide sequences were analyzed phylogenetically. The MCP gene of the starry flounder iridovirus, designated SFIV0909, was identical to that of the turbot reddish body iridovirus (AB166788).

  • Fatigue tests by axial loading (R=0.1) were carried out to investigate fatigue crack growth properties of small surface cracks in mild steel at room temperature, 250.deg. C and 400.deg. C, by using flat specimens with a small artificial pit. All the data of the fatigue crack growth rate obtained in the present tests are determined as a function of the stress intensity factor range, so that the applicability of liner fracture mechanics to the fatigue crack growth of surface cracks at elevated temperatures is investigated and discussed in comparison with the data of type 304 stainless steel at room temperature and elevated temperature. The obtained results are as follows: 1) Relations of both surface fatigue crack length and its depth to cycle ratio fall within a narrow scatter band in spite of different stress levels. 2) The .DELTA. .sigma. .root. .pi. a-da/dN relation of surface fatigue crack growth at room temperature is independent of the stress level and can be plotted as a straight line at log-log diagram, but the relation at 400.deg. C depends partly on the stress level. 3) Relations of the fatigue crack growth into depth d(2b)/dN and is stress intensity factor range .DELTA. $K_{I}$, accounted for the aspect ratio variation, fall within a narrow scatter band for wide range of the applied stress levels. And .DELTA. $K_{I}$E-d(2b)/dN relations of mild steel at different stress level coincide relatively well with the data of type 304 stainless steel. 4) The value of aspect ratio obtained by a beach mark method and a temper coloring method approaches about 0.9 in common with crack growth and it is independent of stress level and temperatures. 5) The equi-crack length curve is parallel to S-N$_{f}$ curve at elevated temperatures.s.s.s.

  • Noting that there is an increasing trend of the so-called 'neo-single life style' among women these days, this research aims to make a product development for these neo-single women in this era of families of a single member by analyzing their concepts and characteristics. We payed a particular attention to the data from such sources as newspapers, magazines or the articles in the Internet. The essence of our research lies in the analysis of target market, in the suggestions in the brand planning and product development and in the designs of fashion and interior products for them. The result of this research is as follows. First, it turns out that these neo-single women enjoy a kind of multi-mixing code lifestyle rather than showing a preference for a particular brand. For this reason, we have decided to pursue a multi-concept brand fonn as a right direction for brand planning for them. Second, as for a philosophy behind the brands, we suggest a concept of 'small utopia' for neo-single women and express such as new aristocracy, happiness and pleasure. Third, we adopt 'YOU' as the name of the brand as it reflects their various life styles and characteristics. Fourth, as for the product development of F/W in 2007, we have decided on 'Minimal Natural' as it mixes up the concepts of the controlled beauty of sophistication and multi-functional elements and 'Modern Primitive' as it expresses the ethnic elements on modern images having craft factors and modern images. We have performed concrete tasks in creating images, coloring, making fabrics for each theme. Fifth, we have chosen and suggested other products that are suitable for these neo-single women who seek for multi-functional but simple kinds after surveying a wide range of products in magazines or in the Internet.

  • 본 논문은 근대 풍경화와 과학(영상)도구와의 연관성을 탐구하고자 한다. 18세기 유럽의 풍경화가들이 자연경관과 인공적 설치물(건물 등)을 그리는 작업에서 근대 과학의 도움으로 만들어진 영상기구들인 카메라 옵스쿠라와 카메라 루시다 등을 사용했던 사실에 근거하여, 이 논문에서는 당시에 유명한 풍경화가들이자 증거자료들이 비교적 분명히 남아있는 이탈리아의 안토니오 카날레토(Antonio Canaletto/Canal 1697-1768)와 영국의 토마스 샌드비(Thomas Sandby 1721-98), 과학자 윌리엄 H F 탈보트(Willian Henry Fox Talbot 1800-77)의 경우를 중심으로 과학적 영상도구를 사용한 이유와 작업과정에 대해 알아보고, 그 사용에서 장단점들과 더불어 미학적인 문제들을 분석하고자 한다. 당대의 풍경화가들이 카메라 옵스쿠라/루시다 같은 기구를 이용했을 때의 장점들은 빠른 스케치 작업으로 인한 시간 절감, 자연/현실의 충실한 묘사, '정확한' 원근법적 구도의 구현에 있다. 그러나 이 기구들이 사용된 스케치들은 부분적으로 부정확하거나 단순화된 묘사가 보이기도 한다. 또 과학적 영상기구를 사용해서 예술작업이 기계의 메카니즘에 종속 문제가 있는데, 이 기구들은 스케치/드로잉에 사용되었고, 화가의 본격적인 그림작업, 즉 자연 해석과 채색·질감·명암 배합 같은 조형적 과정이 남아있으므로, 이들은 '회화작업에 도움을 주는 보조도구'일 뿐이었고, 화가의 창조적인 작업과정에 전혀 지장이 되지 않는다.

  • 본 연구는 토파즈의 인공착색 처리 방법을 설정하기 위하여 브라질, 중국, 인도, 나이지리아, 스리랑카 등 5개국에서 산출된 토파즈를 대상으로, 전자현미분석(EPMA), 중성자활성분석(NAA), X선 회절분석, 라만 분광분석, 주사현미경(SEM), 부식시험, 굴절률측정, 비중측정, 유체 포유물 관찰 등의 실험을 실시하여 광물학적, 화학적 특성에 관한 연구를 수행하였다. 연구 결과 토파즈는 산지에 따라 화학적, 구조적 및 물리적 특성의 차이를 나타내었으며 특히, F와 OH 고용체 함량의 차이는 물리적, 구조적 특성과 밀접한 관련성이 있음이 확인되었다. F에 대한 OH로 치환정도가 가장 높은 인도산 토파즈는 굴절률, 단위포상수 b, 단위포 체적 및 ${\Delta}021$값이 가장 크고, 비중값은 가장 작으며 스리랑카산, 중국산, 브라질산, 나이지리아산순으로 F에 대한 OH로 치환 정도가 낮다. F에 대한 OH로 치환정도가 가장 낮은 나이지리아산 토파즈는 굴절률, 단위포상수 b, 단위포 체적 및 ${\Delta}021$값이 가장 작고, 비중값은 가장 크다. 토파즈내에 함유되는 미량원소종은 Na, Fe, Br, Co, Ce, La, Sm, Th, Au, Sc, Cr 등이며 이러한 미량원소의 정성정량적 특성은 물리적 특성에는 거의 영향을 미치지 않았다. 라만 분광분석 결과 토파즈의 피크는 산지에 따라 강도의 차이를 나타내었으며 브라질산과 인도산은 455∼458($cm^{-1}$)근처의 피크, 중국산은 282∼284($cm^{-1}$) 근처의 피크가 나타나지 않았다. 산지에 따른 결정구조결함 특성은 주로 point-bottom pit의 negative crystal defect(인도산, 나이지리아산)와 curl-bottom pit의 net work defect(브라질산, 중국산)로 구분되며, 결정내에 발달하는 미세한 균열을 따라 형성된 선결함 양상(linear defect)을 보여준다. 유체 포유물의 특징은 브라질산이 액상 $CO_2$를 가지는 III형이고, 중국산에는 유체 포유물이 거의 관찰되지 않으며 단지 $10{\mu}m$이하의 매우 작은 크기인 초생포유물의 극소량 존재한다. 인도산은 기체가 풍부한 II형이고, 나이지리아산은 암염, 실바이트 등의 고체 포유물을 함유하는 IV형이며 스리랑카산은 거의 대부분의 유체 포유물이 2차 생성의 I형이 주로 형성되어 있다. 본 연구의 결과는 광물학적 특성의 차이를 갖는 산지별 토파즈의 인공착색을 위한 처리 방법을 설정하는 유용한 기초 자료로 이용될 수 있을 것이다.

  • This study evaluated the effects of breed and gender in Duroc (D), Pietrain (P), and crossbred (DP) pigs. Loin samples were collected from D (n = 79), P (n = 42), and DP (n = 45) pigs. Intramuscular fat content was significantly lower in P (p < 0.001), and pH was lowest in DP pigs (p < 0.001). Gilts had higher intramuscular fat (IMF) and pH values than did castrated males (p < 0.05). Water-holding capacity was lower in DP pigs than that in D and P pigs (p < 0.001). Shear force in DP pigs was higher than that in D and P pigs (p < 0.001). Lightness and yellowness of meat in DP pigs was increased compared with coloring of P pig meat (p < 0.01). Meat from DP pigs was redder compared with meat from in D and P pigs, and it was higher in gilts than in castrates (p < 0.001). The C16:0 content was lower in P and DP pigs than in D pigs (p < 0.01). C18:2 content was higher in P and DP pigs than in D pigs (p < 0.001). Unsaturated and saturated fatty acids increased in P pigs compared with levels in D pigs (p < 0.05). Our results suggest that meat quality can be controlled by crossbreeding to increase or reduce selected properties. This study provides the basic data on the meat characteristics of F1 DP pigs. Thus, further study should be conducted to estimate the meat quality of various crossbreeds.
