In this paper, we investigate the feasibility of a strategy of failure detection and identification. The point of proposed strategy includes a pattern extraction approach for failure identification using Auto-Associative Kernel Regression (AAKR). We consider a simulation data concerning 605 signals of a Generic Pressurized Water Reactor(GPWR). In the application, the reconstructions are provided by a set of AAKR models, whose input signals have been selected by Correlation Analysis(CA) for the identification of the groups. The failure pattern is extracted by analyzing the residuals of observations and reconstructions. We present the possibility of extraction of patterns for six failure.

We have developed an ultra wide-field of view Optical Coherence Tomography(OCT) which has capability to 2D and 3D views of cross-sectional structure of in vivo human retina. Conventional OCT has a limitation in visualizing the entire retina due to a reduced field of view. We designed an optical setup to significantly improve the lateral scanning range to be more than 20 mm. The entire human retinal structure in 2D and 3D was reported in this paper with the developed OCT system. Also, we empirically searched an optimized image size for real time visualization by analyzing variation of the frame rate with different lateral scan points. The size was concluded to be $1024{\times}2000{\times}300$ pixels which took 9 seconds for visualization.

The new government proposed the expansion of the basic research program as one of the most important R&D goals until 2022. Even though the basic research program occupies only a quarter of total university R&D, it is regarded as the most important standard representing excellency of both research and researcher. Thus the expansion of the program inevitably effects the conduct of other R&D programs, such as applied, development, and cooperation with private sector. However, in the course of implementing the policy, there were little consideration of the changes that the expansion would bring, nor detailed analysis on the current status of university R&D. More important is that the expansion of university R&D should lead to the growing number of Ph. D’s. It is asserted that deterioration of Ph. D labour market condition is already a serious problem, and the R&D policy must go on with HRD policy. In Korea, there are more than 200 universities and most of then educate Ph. D students. However, the differences in R&D competence among them is very large; some reach the world-class level, while others struggles even with the recruitment of graduate school student. In this research, we have classified universities into 6 groups, depending on their location, governance and size, and analysed the characteristics of their R&D performance. Based on the results, we proposed the new policy direction of university R&D aiming to strengthen the capacity and social role of universities.

In this study, we have brought into the discussion the autonomy and responsibility of research. Academic freedom has been regarded as the one of the inherent human rights, and been secured through the constitutional law in many countries. Below it lies the belief that autonomy is not only necessary but also the origin of creativity in academic work. However, there is no generally agreed concept on the nature of academic freedom. The debate about academic freedom ranges from definition or meaning to the extent it reaches. Further, the different level of academic freedom such as individual and institutional might bring conflict with each other. Moreover, responsibility has been accepted as the other side of freedom, but it also has been marked by a lack of clarity. Both autonomy and responsibility have not been paid much attention in science policy realm. With this in mind, we have attempted to define autonomy and responsibility of especially in publicly funded research. Autonomy is defined as the independence from interference with internal norm. When science was regarded as a common good, the curiosity-driven research was supported by public with a wide range of autonomy and freedom. However, the size of public funding to science grows and the socio-economic role of science gains more importance, the responsibility of science becomes dominating the freedom of research. We have proposed the elements of autonomy and responsibility of public research based on preceding studies, and presented preliminary survey on this familiar but unexplored topic.

The expansion of the basic research program is one of the most important R&D goals until 2022 in this government. The basic research program it is regarded as the most important program since it represents the excellency of research and researcher. Thus it plays the central role in university-led R&D, and the expansion is expected to affect the conduct of other R&D programs, such as applied, development, and cooperation with private sector. In this research, we have investigated the effect and impact of the expansion of basic research program during 2017-2019. Universities are classified into 6 groups, according to previous work and we have analysed the characteristics of their R&D performance. We have concluded that the policy are achieved the desired goal of strengthen research capability of researcher. However, as to the capability of university, the basic research program has limits and must be accompanied by other supporting programs such as BK21 and R&D programs. Based on the results, we proposed the new policy direction of university R&D aiming to strengthen the capacity and social role of universities.

영상 스티칭은 다수의 영상을 넓은 시야각의 단일 영상으로 합성하는 기술로써 군사, 의료, 천문 등 다양한 분야에서 활용되고 있다. 정확한 영상 스티칭을 위해서는 입력 영상 간의 공통 영역 탐색이 중요한데, 주로 특징점(Keypoint)을 활용하는 특징 기반 서술자가 활용되고 있다. 이때 특징점은 밝기, 회전 등 변환에도 동일 영역을 나타내는 지점을 지칭하지만, 입력 영상 간에 밝기나 시점이 크게 다른 경우에는 다른 지점의 특징점이 추출될 수 있기에 매칭 정확도가 저하될 수 있다. 또한, 영상 내 지나치게 많은 특징점 후보가 있거나 매우 적은 경우에도 매칭 정확도가 저하될 수 있다. 최근에는 딥러닝 기반 특징점 추출 및 매칭 알고리즘이 제안되었으며, 영상 간의 밝기나 시점이 크게 다른 상황에서도 특징점 매칭이 가능한 것을 실험으로 나타냈다. 그러나 특징 기반 특징점 추출 및 매칭의 정확도 평가는 True Matching과 False Matching을 선택하는 과정에서 객관성이 떨어지는 방법으로 진행되고 있다. 이에 본 논문에서는 매칭된 특징점을 활용한 Task 결과의 정확도를 통해서 특징점 추출 및 매칭 정확도를 평가하는 특징 기반 서술자 간 특징점 추출 및 매칭 정확도 평가 방법을 제안하고자 한다.

고급중학교 『국어문학』교과서에 나타난 북한 문학교육의 특성 - 현대소설/영화 단원을 중심으로 -

박기범(Park, Kibeom) 국어문학회 2020 국어문학 Vol.73 No.-

이 글은 북한의 현행 2013 개정 교육과정에 따른 고급중학교 〈국어문학〉 과목의 교과서와 교수참고서를 대상으로 북한에서 이뤄지고 있는 현대소설/영화 교육의 특성을 살펴본 것이다. 이를 통해 알 수 있었던 북한의 문학교육과 현대소설/영화 교육의 특성은 다음과 같다. 북한은 〈국어문학〉 과목을 통해 국가에 이바지하는 충성된 인재를 양성하기 위해 문학작품을 중심으로 정치사상 교양과 혁명적 정서를 키워주는 동시에 사회생활에 필요한 말과 글, 문학에 대한 지식과 기능을 충분히 체득시키는 것을 교육목적으로 삼고 있다. 북한의 『국어문학』 교과서는 주제 중심으로 편성되었고, 이전 교육과정기의 교과서에 비해 더욱 실질적이며 체계적인 단원 구성을 취하고 있다. 북한은 학년이 올라갈수록 소설의 비중이 더 커지며 수록 분량도 많아진다. 또한 해방 이전의 작품보다 해방 이후의 작품이 많으며 세계 명작도 초기자본주의 시대를 배경으로 한 작품을 활용하였다. 작품의 주제는 대부분의 작품이 김일성 일가와 조국에 대한 충성으로 수렴될 수 있으며, 토지개혁, 조국해방전쟁, 천리마작업반운동, 농촌경제의 개조, 철도건설, 광산개발 등의 시대적 사건들을 배경으로 하여 평범한 인물이 사회주의적 영웅으로 성장해 가는 모습과 그 활약상을 그린 작품, 과학기술이나 근면한 생활태도를 중시하는 작품들이 실렸다. 이러한 작품 선정은 북한의 역사관과 문학사에 근거한 것이다. 북한은 작품의 갈래에 관한 지식이나 작가의 문학적 업적에 관한 내용도 비중 있게 다루고 있다. 또 북한에서는 영화를 교육 제재로 상정하여 영화에 관한 다양한 학습활동을 도모하고 있다. 『국어문학』 교과서에서는 ‘지식 습득→문학작품을 매개로 한 다양한 언어 사용 활동→태도 형성’으로 학습활동이 전개되도록 하여 초등교육부터 중등교육까지 높은 학년으로 갈수록 문학을 중심으로 좀 더 심화 발전된 언어활동을 통해 통합적인 언어 사용 능력 배양하도록 하고 있다. 이와 같은 교재 차원의 탐구가 향후 남북한 통일 이후의 문학교육의 방안을 설계하는 데 유용한 참고가 될 수 있기를 기대한다. This article examines the characteristics of modern novels/film education in North Korea, targeting textbooks and guidebooks for high school 〈Korean Language and Literature〉 according to the current 2013 revised curriculum of North Korea. The characteristics of North Korea"s literary education and modern novel/film education are as follows. In order to cultivate loyal talents who contribute to the country through the 〈Korean Language and Literature〉 course, North Korea fosters ideological education and revolutionary sentiment, focusing on literary works. It is for educational purposes to get enough mastery. North Korea"s 『Korean Language and Literature』textbooks are organized around themes and have a more substantial and systematic unit structure than before. The higher the grade, the bigger the proportion of novels, and the bigger the volume. Also, there were more works after the liberation than those before the liberation, and the world masterpieces also used works based on the early capitalist era. Almost all of the subjects of the work can be converged with loyalty to the family of Kim Il-sung and his country. In the background of the events of the times, ordinary figures grow as socialist heroes, works depicting their achievements, and works focusing on science and technology and hard work. The selection of these works was based on North Korean history and literary history. North Korea also focused heavily on genre knowledge and the author"s literary work. In addition, North Korea was pursuing various educational activities related to film by considering it as an educational sanction. Learning activities are developed through ‘acquisition of knowledge → activity of various languages through literary works → formation of attitudes.’ Integrated language literacy. It is hoped that such a textbook inquiry can be a useful reference for designing literature education after the reunification of the two Koreas.
