In vitro 소화시 계란 성분이 anti-Y ruckeri IgY 항세 활성을 안정화시키는데 어떡해 관여하는지를 SDS-PAGE와 ELISA로 조사한 결과는 다음과 같다. Anti-Y ruckeris IgY 항체와 난황 및 난백으로 혼합 후 펩신으로소화시킨 후 경우 1시간 후 난황 및 난백이 혼합된 시료에서 모두 anti-Y ruckeri IgY 항체의 heavy chain과 light chain이 분해는 되었지만 어느 정도 밴드를 관찰할 수있었으며, anti-Y, ruckeri IgY 항체 활성 측정한 결과 난황시료는 35%, 난백시료는 61%의 항체 활성을 유지시켰다. Anti-Y ruckeri IgY 항체와 오보알부민, 오보뮤우신, 라이소자임 및 오보뮤코이드를 혼합 한 후 펩신으로 소화시킨 경우 1시간 우에는 anti-Y, ruckeri IgY항체의 heavy chain의 밴드르 fdjsm 정도 볼 수 있는 형태로 나타났으며, anti-Y, ruckeri IgY 항체의 light chain는 오보뮤우신 및 오보뮤코이드가 홉합되어 펩신으로 소화시킨 경우 1시간 후에는 밴드를 거의 볼수 없었으나 오보알부민 오보트란스훼린 및 라이소자임에 혼합된 시료에서 밴드를 관찰할수 있었다. 특히 라이소자임과 오보트란스훼린의 경우 펩신 호화 2시간 우에도 anti-Y, ruckeri IgY 항체의 light 밴드가 관찰되었다. 펩신소화 1시간 후에 난백성분이오보알부민, 오보뮤우신, 라이소자임, 오보트란스웨린 및 오부뮤코이드 중에서 단지 오보트란스훼린만이 38%의 anti-Y, ruckeri IgY 항체 활서을 보인후 2시간 후에도 15% 정동의 활성을 나타내었다. anti-Y, ruckeri IgY항체와 난백 및 전란을 혼합한 다음 무지개송어 위 추출액으로 소화시 2시간 후에 난백은 14%, 전란은 69%로 anti-Y, ruckeri IgY 항체 활성을 유지시킨 것으로 나타났다.X> $e_{I}$ WPi_BE_QE]]]]]로 상징하며 WLWQ에 적용되는 몇 가지 제약을 관찰하고 이를 일반적인 언어원리로 설명한다. 첫째, XP는 주어로만 해석되는데 그 이유는 XP가 목적어 혹은 부가어 등 다른 기능을 할 경우 생략 부위가 생략의 복원 가능선 원리 (the deletion-up-to recoverability principle)를 위배하기 때문이다. 둘째, WLWQ가 내용 의문문으로만 해석되는데 그 이유는 양의 공리(the maxim of quantity: Grice 1975) 때문이다. 평서문으로 해석될 경우 WP에 들어갈 부분이 XP의 자질의 부분집합에 불과하므로 명제가 아무런 정보제공을 하지 못한다. 반면 의문문 자체는 정보제공을 추구하지 않으므로 앞에서 언급한 양의 공리로부터 자유롭다. 셋째, WLWQ의 XP는 주제어 표지 ‘는/-은’을 취하나 주어표지 ‘가/-이’는 취하지 못한다(XP-는/-은 vs. XP-가/-이). 이는 IP내부 에 비공범주의 존재 여부에 따라 C의 음운형태(PF)가 시성이 정해진다는 가설로 설명하고자 했다. WLWQ에 대한 우리의 논의가 옳다면, 본 논문은 다음과 같은 이론적 함의를 기닌다. 첫째, WLWQ의 존재는 생략에 대한 두 이론 즉 LF 복사 이론과 PF 삭제 이론 중 전자의 입장을 지지한다. 둘째, WP를 XP로부터 복원할 때 부분 자질만 복사된다. 이는 어휘가 통사층위로 들어온 이후에도 어휘 자질들이 완전히 동결되는 것이 아니라 계속 지시될 수 있다는 가설을 지지한다.

Batch process TRN(Terrain Relative Navigation) using an altimeter is a technique to correct position by correlating a series of periodically measured terrain height profile and terrain height candidate profile of the DEM(Digital Elevation Map). However, it is generally known that the performance of TRN is degraded when measured terrain height profile and terrain height candidate profiles of the DEM are similar at hill or repetitive terrain. In this paper, area based terrain slope roughness index[11] is applied and area based terrain curvature roughness index which can detect similarity of terrain in ROI(Region Of Interest) is proposed to overcome this problem. Applying terrain roughness indexes to terrain relative navigation system of lunar lander, it is shown that TRN using area based terrain roughness results in improved performance compared to conventional trajectory based method through simulation.

This paper proposes multi-camera system that relies on 3D views for panoramic video and distribution method about panoramic video generation algorithm by using cloud computing. The proposed monitoring system monitors the projected 3D model view, instead of individual 2D views, to detect image distortions. This can minimize compensation errors caused by parallax, thereby improving the quality of the resulting panoramic video. Panoramic video generation algorithm can be divided into registration part and compositing part. Therefore we propose off-loading method of these parts with cloud computing for panoramic video service.

The purpose of this study was to find out about the awareness and demands of pre-service and in-service elementary school teachers on STEAM education. For the purpose of this study, researcher administered survey questionnaires were conducted for 160 pre-service teachers and 191 in-service teachers who were sampled by convenience sampling method. The results were as follows. On the awareness and demand for knowledge and necessity on STEAM, first, on the understanding related knowledge, most respondents have heard of STEAM education(97.7%), and well aware of STEAM(91.4%) through the teacher training course(80.3%). Second, on the necessity, 60.4% respondents were located in "very necessary" and "necessary" entry. On the awareness and demand for applying STEAM, first, on the reasons of applying STEAM was to help the cognitive and affective development. Also 67.3% respondents would like to apply STEAM on their science class. The reason was necessity on STEAM, and the most suitable subject for blending with science of applying to STEAM was technology, on the other hand the most difficult subject was art. Second, on the effect of STEAM, most respondents had positive awareness on the all categories. Third, on the purpose of science education, also had positive awareness on the all categories of the purpose of science education. On the awareness and demand for blending ways of STEAM and improvements, first, on the blending ways of STEAM, topic centered blending related to real life had a majority. Second, on the improvements, to improve the STEAM education, many respondents pointed out the development of teaching and learning STEAM program and dissemination of related resources.

This study investigates an event detection method with the aim of generating an event-focused news summary from a set of news articles on a certain event using a multi-document summarization technique. The event detection method first classifies news articles into the event related topic categories by employing a SVM classifier and then creates event clusters containing news articles on an event by a modified single pass clustering algorithm. The clustering algorithm applies a time penalty function as well as cluster partitioning to enhance the clustering performance. It was found that the event detection method proposed in this study showed a satisfactory performance in terms of both the F-measure and the detection cost.

In this paper, we present a mathematical modeling and perform a performance analysis of double-dwell serial search algorithm, which has a search window concept, for pilot channel in DS-CDMA(Direct Sequence Code Division Multiple Access). We derive a code detection function, a false alarm function, a code miss function, and a mean code acquisition time for the performance analysis. We calculate the mean code acquisition time of the mathematical model in IS-95 forward link and compare it with that of the conventional search methods. The performance of the code acquisition system is also evaluated to investigate the effect of dwell times and search window size. The JTC channel model, which is a PCS channel model in North America, is used for the analysis. The numerical result shows that the mean code acquisition time of the double-dwell serial search algorithm with a search window is reduced by about 17%~25% than those of the conventional ones.

This study was conducted to improve the standard method for vitamin B₁₂ and biotin contained in foods for special dietary uses to ensure the specificity of the complex matrix properties of foods. For the food code, the test method was improved to determine vitamin B₁₂ and biotin by high-performance liquid chromatography (HPLC)-UV using column-switching after concentration using immunoaffinity column. The immunoaffinity columns contain a gel suspension of monoclonal antibody specific to the vitamin of interest so that it can be used to concentrate the vitamin B₁₂ and biotin and remove interferences from the food extracts. Moreover, validation of advanced new methods was carried out to support the suitability of the proposed analytical procedure (specificity, linearity, detection limits (LOD), quantitative limits (LOQ), accuracy, and precision). The improved analytical method is being used to monitor relevant food items on sale. The results of this study showed that the new analytical method is suitable and appropriate for managing food intended for special dietary uses.

Dong-a Ilbo tried to assume leadership of opinion in preceding the movement against the trusteeship as a mouthpiece for the Han-Min Party. Dong-a Ilbo was to try to promote the atmosphere of anti-trusteeship=anti-communism=anti-Soviet Union, distorting the decision of a conference of three foreign affairs ministers in Moscow. It was not an incorrect report, but the false report. As a result, the formula of an anti-trusteeship=anti-Soviet Union=anti-communism=patriotism, and a pro-trusteeship=pro-Soviet Union=pro-Communism=traitor was formed. And the important problems of land reform and pro-Japanese‘ clearance were missing. Historically, political newspapers had appeared in the periods of very important political change. Political newspapers played a role as mouthpiece for political party or group. Dong-a Ilbo was such a political newspaper. It was that Dong-a Ilbo tried to change the social atmosphere in preceding the movement against the trusteeship as a mouthpiece for the Han-Min Party. And history was distorted.
