Rapeseed(Brassica napus L.) is an important oil crop as a vegetable oil, concentrated feed and industrial materials. The name "canola" was registered in 1979 by the Western Canadian Oilseed Crushers Association to describe "double-low" varieties. Double low indicates that the processed oil contains less than 2% erucic-acid and the meal less than 3mg/g of glucosinolates. Today annual worldwide production of rapeseed is approximately 35 million tons on 24 million hectares. China accounts for 33% of the world production and the European Economic Community for nearly 32%. Canola ranks 3rd in production among the world's oilseed crops following soybeans, sunflowers, peanuts and cottonseed. The recent advances in genomics and in gene function studies has allowed us to understand the detailed genetic basis of many complex traits, such as flowering time, height, and disease resistance. The manipulation of seed oil content via transgene insertion has been one of the earliest successful applications of modern biotechnology in agriculture. For example, the first transgenic crop with a modified seed composition to be approved for unrestricted commercial cultivation in the US was a lauric oil, rape-seed, grown in 1995. There were also some significant early successes, mostly notably the achievement of 40% to 60% lauric acid content in rapeseed oil, which normally accumulates little or no lauric acid. The name "$\textrm{Laurical}^{TM}$" was registered in 1995 by Calgene Inc. Nevertheless, attempts to achieve high levels of other novel fatty acids in seed oils have met with much less success and there have been several reports that the presence of novel fatty acids in transgenic plants can sometimes lead to the induction of catabolic pathways which break down the novel fatty acid, i.e. the plant recognizes the "strange" fatty acid and, far from tolerating it, may even actively eliminate it from the seed oil. It is likely that, in the future, transgenic oil crops and newly domesticated oil crops will both be developed in order to provide the increased amount and diversity of oils which will be required for both edible and industrial use. It is important that we recognize that both approaches have both positive and negative points. It will be a combination of these two strategies that is most likely to supply the increasing demands for plant oils in the 21st century and beyond.ant oils in the 21st century and beyond.

The cultivation area and use of genetically modified (GM) crops have been increased continuously over the world. Concerns about the potential risks of GM crops are also increasing. Safe management for the development and production of GM crops is required according to Living Modified Organism Act in Korea. Planning about the methods, duration, and frequency of environmental monitoring is also required for commercial use of GM crops. GM Zoysia japonica Steud. (event name: JG21) expressing resistance to glufosinate-ammonium has been generated previously. By using gamma ray treatment to JG21 we also developed male sterility and dwarf Z. japonica (event name: JG21-MS). The objective of this study was to establish the monitoring system for environment release of JG21-MS. In this study we extracted RNA from JG21 and JG21-MS and conducted RAPD (random amplified polymorphic DNA) method to distinguish JG21 and JG21-MS.

이 논문의 목적은 아직까지 명확하게 밝혀지지 않은 조보의 기원 문제를 다시 한번 검토해보고, 조보의 명칭 및 폐간시기 문제를 비롯하여 기문기사 성격, 선조 때 발생한 민간인쇄조보 발행사건 등에 초점을 맞추어 살펴보는 데 있다. 내부적 통보매체인 필사조보는 조선왕조 초기에 해당하는 15세기 말경(대략 성종대)에 탄생하여 중종조에 체계적인 발전을 이룩하였으며, 정부의 인쇄관보와 한말의 유수한 민간일간지들이 발행되었던 1907년 11월(승정원의 왕명출납기능을 수행하였던 비서감이 폐지됨)까지 지속적으로 발행된 것으로 추정된다. 조보의 명칭 가운데 가장 보편적으로 사용된 용어는 조보(朝報)였고 그 다음이 저보(邸報)였다. 다음으로는 조지(朝紙), 기별(奇別), 난보(爛報), 경보(京報)의 순이었으며, 나머지 용어들 예컨대, 기별지(奇別紙), 저장(邸狀), 저지(邸紙), 보장(報狀), 한경보(漢京報), 영기(營奇) 등은 거의 사용되지 않았다. '기별'은 조선조 중반(중종대-인조대)에, '조지'는 조선조 후반(숙종대-고종대)에 집중적으로 사용되었다. 필사조보는 폐쇄성과 난초체라는 속기로 필사되어 주요 독자층인 사대부들이 구독하기가 매우 불편하였으므로 1577년(선조 10년) 8월 서울에 사는 수명의 민간인(양민층인 기인(其人))들이 의정부와 사헌부로부터 발행허가를 얻어 목활자로 인쇄조보를 발행하였다. 민간인쇄조보가 약 3개월 동안 발행된 시점에, 선조는 "사국(史局)을 사설화(私設化)하고 국가기밀을 누설할 가능성이 있다"는 이유로 폐간조치하고 신문발행 관련자 30여 명을 유배시키고 언론 양사(사헌부와 사간원)의 책임자를 경질하는 조치를 취하였다. 조선시대 일부 기인(其人)들이 중국 인쇄조보를 본 떠 만든 민간인쇄조보(목활자본)는 그당시 중국의 인쇄신문 형태(길이 $20{\sim}25cm$, 폭 $10{\sim}15cm$, 면수 $5{\sim}10$쪽)와 비슷했을 것으로 추정된다. 민간인쇄조보는 선조의 탄압정책으로 약 3개월 만에 폐간되는 비운을 맛보았지만 영리를 목적으로 민간인이 발행하고 활판인쇄술을 세계 최초로 채용하여 발행하였다는 점에서 세계 최초의 '활판인쇄 상업일간신문'일 가능성이 매우 높은 신문이다.

2011년부터 수입되어 사육 유통되는 슈퍼밀웜의 국내 샘플들은 형태 분류학적 검토를 통하여 Zophobas atratus란 종으로 밝혀졌고, Z. morio란 학명은 이 종의 동물이 명임이 확인되었다. 이 외래종은 자원 관리측면에서 국명을 '아메리카왕거저리'로 신칭하였다. 이 종과 형태적으로 유사한 자생종 P. valgipes 및 사육종 T. molitor와 DNA 바코드 분석 결과, Zophobas atratus와 P. valgipes는 평균 21.4%, Zophobas atratus와 Z. morio는 20.9%의 염기분화율을 보여 DNA 바코드로 쉽게 종 동정할 수 있음을 확인하였다. Z. atratus의 국내집단은 모두 동일 일배체형을 갖고 있어 국외의 동일 지역 개체군이 국내로 유입된 것으로 추정된 반면에 Z. molitor는 동일 사육집단 내에서도 두 개의 종내 집단이 뚜렷이 구분되고 서로의 염기 분화율이 1.17 ~ 2.19%로 갭을 형성한 것으로 보아 국내 Z. molitor 사육개체들은 서로 다른 지역 집단이 혼입되어 대량 사육에 이용되어진 것으로 추정된다. 이번 연구를 통하여 분석된 상업적으로 도입, 이용되는 2종의 거저리류의 분류학적 기초 정보가 국내 곤충자원 관리를 위하여 유용하게 이용될 것으로 판단된다.

The acute and subacute hypoglycemic and antihyperglycemic effects of drinkable ripe onion juice (Commercial product name is "Black Onion Extract") were investigated in normal and streptozotocin-induced diabetic rats. For tests of acute and subacute hypoglycemic effects, ripe onion juice (5 and 15 mL/kg b.w.) was administered by oral gavage to normal Sprague Dawley rats and measurements of fasting glucose levels and oral glucose tolerance tests were performed. Tolbutamide was used as a reference drug at a single oral dose of 250 mg/kg b.w. To test anti-hyperglycemic activity, the ripe onion juice was administered to streptozotocin-induced diabetic rats by oral gavage at single dose of 15 mL/kg b.w. per day for 7 consecutive days. Oral administration of the ripe onion juice at either dosed level of 5 or 15 mL/kg b.w. showed no remarkable acute hypoglycemic effect in normal rats. The two dosed levels caused a relatively small reduction, only 18% and 12% (5 and 15 mL/kg b.w., respectively) decrease in glucose levels at 2 h after glucose loading in normal rats. However, at 3 h after glucose loading, blood glucose levels in the ripe onion juice-dosed rats were decreased to the corresponding blood glucose level in tolbutamide-dosed rats. Although showing weak hypoglycemic potential compared to that of tolbutamide, oral administration of ripe onion juice (15 mL/kg b.w.) for a short period (8 days) resulted in a slight reduction in the blood glucose levels that had elevated in Streptozotocin-induced diabetic rats. In conclusion, these results suggest that the commercial product "Black Onion Extract" may possess antihyperglycemic potential in diabetes.

The purpose of this study is to analyze the various signs seen on TV commercials for school uniforms since year 2000, thus uncovering the connotative meanings in them. For this study, the semiotic approach has been used. The signs seen on the TV commercials are separated into linguistic and visual signs. They are found to have symbolic connotations. The results are as follows: First, there are plenty of signs expressing the sense of belonging to the student group and sense of conformity to his or her peer group. They are intended to garner their collective identity in the peer group of teenagers. Second, the TV commercials express the self that is realizing one's value dynamically. The frequent designation of 'I', 'me' and 'myself' represents that I am at the center of the world. Furthermore, the suggestion of diverse student roles beyond mere academic pursuits symbolically shows the ideal self that most teenagers wish to have. Third, the TV commercials implied a commercial ideology. That is expressed in the emphasis on aesthetic value that teenagers can realize their self only by consuming expensive school uniform brands. Forth, there are many signs related to appearance and appearance care. They are expressed with very specific signs such as 3 : 7 proportion, long legs, small face, and so on. Repeating or emphasizing the importance of looks and a certain brand name as the tool to accomplish better looks indicates that it contains the ideology of appearance management.

The color of an esthetic restorative material is controlled primarily by thickness of the material and background color. Although the effects of the two factors on the color coordinates of esthetic dental materials have been reported, the mechanism has not been clarified well enough to explain the effects quantitatively. The purpose of this study was to evaluate the effect of thickness and background color on the color of tooth colored restorative materials quantitatively. One hundred sixty samples were fabricated from two commercial light-cured composite resins and two commercial compomers. The color characteristics and changes in the color coordinates were measured by a tristimulus colorimeter (Model TC-6FX, Tokyo Denshoku Co. Japan) using the CIELAB system. The results were as follows: 1. As thickness increased from 1.0 to 4.0mm, values of $L^*$ $a^*$ $b^*$ changed irregulary for white and dentin color background, but showed no obvious difference in color for black background. 2. The colors of composite resins and compomers were significantly influenced by background color. 3. The color difference was recognized even the same shade name in four representative kinds of composite resins and compomers. 4. As thickness changed, values of color difference for same products and same background color showed constancy, but showed difference for different background color.

In May 2012, the collaboration of Hana Bank, top financial service company, and SK Planet, top telecommunication service provider, introduced a new credit card that was filled with all-in-one benefits into the market. Leveraging strong infrastructure of two companies, each top in its own industries, the awareness and preference of 'Club SK Card' brand rapidly increased to about 25% in less than one year. Moreover, this new card was enthroned in the most sold credit card of year 2012, accounting for a market share of 7.2% in the credit card market and more than 80% in the mobile credit card market. To make these results possible, 'Club SK Card' marketing team developed an effective marketing communication strategy which followed the 6M model. The mission of the marketing communication strategy was simple and clear. It was to deliver the card's inherent strengths on consumer benefits that come from the support of subsidiary and affiliated companies of SK Planet. According to OK Cashbag data, the marketing communication team selected the appropriate target consumers and approached them directly, inducing actual purchase behavior. The target consumers received straightforward messages about 'Club SK Card' and were led to join in the new membership at their most frequently visited supermarket or franchise restaurant. The straightforward communication message embedded in an eye-catching commercial ad with a hook song accompanied with a dance was delivered via public media. The ad became so popular that many other television programs quoted or made parodies of the ad. Courtesy of the commercial ad, the brand name disseminated rapidly and widely among the public. In October 2012, an ingenious planning and persistent implementation of the communication strategy results 'Club SK Card' to be ranked top in brand awareness as well as advertising preference tests.
