With the ever-growing demands for larger size and high resolution displays, Micro-light-emitting diode (Micro-LED) displaywith quantum dots (QDs) fi lm as color conversion layers (CCLs) has become one of the most promising candidates offuture display for its advantages in low power consumption and wide color range. In this study, we report a novel full-colordisplay based on blue Micro LED, which has patterned red and green QDs color conversion (QDCC) layers fabricated byinkjet printing (IJP). A structure of double-layer bank was designed to reduce color deviation, prevent crosstalk, and fl attenthe QDCC layer. By optimizing the thickness of the red/green QDCC layers and the wavelength of blue Micro LEDbacklights, a full-color QDCC-LED display with 228 PPI resolution and size of 1.11-inch was successfully fabricated andshowed superb performance. We not only eff ectively reduced crosstalk, but also improved the color conversion effi ciency ofQDs. In addition, this QDCC-LED display prepared by embedded bonding process shows a color gamut of 107.53% NTSC.

PRECISE LARGE DEVIATIONS FOR AGGREGATE LOSS PROCESS IN A MULTI-RISK MODEL

Fengqin Tang,Jianming Bai 대한수학회 2015 대한수학회지 Vol.52 No.3

In this paper, we consider a multi-risk model based on the policy entrance process with n independent policies. For each policy, the entrance process of the customer is a non-homogeneous Poisson process, and the claim process is a renewal process. The loss process of the single-risk model is a random sum of stochastic processes, and the actual individual claim sizes are described as extended upper negatively dependent (EUND) structure with heavy tails. We derive precise large deviations for the loss process of the multi-risk model after giving the precise large deviations of the single-risk model. Our results extend and improve the existing results in significant ways.

Stabilization Analysis for Discrete-Time Fuzzy Systems via Nonuniform Delay Partitioning Technique

Fengqin Xia,Xiaojie Su,Peng Shi 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

This paper is concerned with the stability analysis problem for discrete-time Takagi-Sugeno (T-S) fuzzy systems with time-varying delay. By utilizing the idea of partitioning the delay interval into l nonuniform subintervals and the reciprocally convex technique, a novel fuzzy Lyapunov-Krasovskii function is constructed to reduce the conservatism of stability conditions. The conservatism reduction becomes more obvious with the partitioning getting thinner. Then, on the basis of parallel distributed compensation (PDC) law, the state-feedback fuzzy controller can be obtained for the concerned fuzzy delayed systems. These proposed conditions are given in terms of linear matrix inequalities, which can be solved by standard numerical software.

창극 <메디아>의 문화상호적 각색에 대한 고찰─메디아의 네 차례 ‘범죄’의 극적 구현을 중심으로

sun fengqin 한국극예술학회 2019 한국극예술연구 Vol.0 No.66

Intercultural Theater refers to an experimental theater movement based on acceptance and communication between cultures. It began in earnest in the west during the 1960s and gradually spread around the world. Changgeuk Medea(창극 <메디아>) is the first attempt to achieve " the Changgeolization(창극화) of Greek Tragedy" with the aim of the "globalization of Changgeuk.” The purpose of this study is to find why four crimes associated with Medea, only briefly mentioned in the original story, were embodied in concrete scenes as they were adapted into Changgeuk Medea. The analysis is conducted according to the time sequence of crimes, but the discussion is divided into the changes of character type as revealed in the content, and the reinterpretations of character behaviors highlighted in the form. While imputing her brother's murder to Iason, Changgeuk Medea embodies Medea as an innocent ‘accomplice’ and ‘victim’ of this murder, and transforms Medea's revenge for an individual into a more just revenge for her family. In the story of the killing of her ‘uncle-in-law’, the outward expression of Medea’s guilt and the fact that she is not evil by nature are discussed. The revelation of the new “truths” of earlier crimes provides Medea with sufficient justification for exacting vengeance on her enemies, and she executes it via sorcery upon instigation by God. Regarding the filicide in the story, Changgeuk Medea has interpreted it in a new direction, in this case as a purification ceremony performed for the children through the implementation of ritual act. This study analyzes how the adaptation of Changgeuk Medea was accomplished within the framework of intercultural Changgeuk, the goal of which is globalization. The main purpose of the study is to examine the influence of various aspects of the sociocultural background, such as the social and cultural aspects, national morality, and the national aesthetic psychology of the culture to which the adapter of Changgeuk Medea and its audience belong. 문화상호적 연극은 1960년대에 서양에서 본격적으로 시작하여 점점 전 세계적으로 확산된 문화 간의 수용과 소통을 바탕으로 한 실험적 연극 운동이다. 창극 <메디아>는 ‘창극의 세계화’를 지향하여 “그리스 비극의 창극화”를 최초로 시도한 작품이다. 본 연구는 원작에서 가볍게 언급되는 데 그쳤던 주인공 메디아와 연관된 네 차례의 범죄가 창극 <메디아>로 각색될 때 구체적인 장면으로 구현되게 된 이유를 밝히고자 했다. 이에 관한 분석은 네 차례 범죄가 일어난 시간 순서에 따라 전개하였으나, 크게 내용적으로 드러난 캐릭터 전형의 변화, 그리고 형식적으로 부각된 인물 행동에 대한 재해석으로 나눠서 논의했다. 창극 <메디아>는 동생살해의 죄명을 이아손에게 전가하는 가운데 메디아를 억울한 ‘공범자’이자 피해자의 신분으로 형상화하며, 개인을 위한 메디아의 복수를 가족을 위한 더 정의로운 복수로 각색해낸다. 숙부살해 이야기의 경우, 메디아가 지닌 죄의식을 외적으로 표현하며 그녀의 본성이 사악하지 않다는 점을 드러내고자 한다. 앞선 범죄들의 새로운 ‘진실’에 대한 폭로는 메디아가 원수에게 복수를 행하는 데 있어 충분한 정당성을 마련해 주며, 그녀는 신의 부추김에 따라 무술로 복수를 실행한다. 메디아의 자식살해에 있어서 창극 <메디아>는 제의적인 장면의 구현을 통해 이를 아이들을 위해 행하는 정화의례라는 새로운 방향으로 해석해냈다. 본 연구는 창극 <메디아>의 각색이 세계화를 지향한 문화상호적인 창극이라는 큰 틀 안에서 어떤 방식으로 이루어졌는지를 분석하며, 나아가 창극 <메디아>의 각색자와 이 작품의 관객들이 속한 문화권의 사회, 문화, 민족 도덕관, 민족적 미적 심리 등 여러 사회문화적 배경이 각색에 미친 영향을 주로 살피고자 했다.

<조씨고아>의 서사구조적 연출기법에 관한 비교연구―한국판과 그리스·중국 연합판 공연을 중심으로

In the east, the theatrical tradition is just as strong as that in the west, and this has also provided inspiration for reforming western plays, which face a crisis in the twentieth century. However, also in the east, unlike the enthusiasm for western plays, attention and enjoyment and acceptance of traditional eastern plays have been lacking. There has also been a lack of attempts to combine eastern and western traditional plays with the unique perspective of the Orient. Given this situation, director Koh Sun-Woong's acceptance and adaptation of the Chinese classics represented a significant attempt that uncovered the value and possibilities of classical Chinese plays while also adding to our understanding of plays in neighboring countries. It is also meaningful that director Wang Xiao-Ying took the initiative to incorporate classical Oriental plays, reaching the stage of cultural exchange with the west. Based on earlier work, this article examines narrative structure performance techniques, thus far scarcely touched upon, and compares meaning creation in plays, amplifications of tragedy, and the formation of inner structures by analyzing the structure performance techniques of the two aforementioned adaptations. Specifically, this article initially analyzes the composition of the narrative structure in the original work and the plot changes in the two adaptations. Based on these findings, the analysis turns to the types of new meanings that arise and how they affect the amplification of tragedy through the various uses of a repetitive narrative structure, which is a structure feature. Moreover, taking note of hidden characters used in both adaptations, this article looks at how their insertion adds a three-dimensional inner structure to the original structure. 동양에도 서양 못지않은 연극적 전통이 있는데 그것은 20세기 들어 위기에 처한 서양 연극을 개혁하는 데 영감을 제공하기도 했다. 그러나 동양에서는 서양 연극에 대해 열중하고 있는 것과 달리, 동양 전통극을 즐기고 수용하는 데에는 관심을 기울이지 못했다. 또한 역으로 동양의 고유한 시각으로 동양 전통극과 서양 연극을 용합시켜 연출하려는 시도도 역시 부족했다. 이러한 배경하에 고선웅 연출의 중국 고전에 대한 수용과 각색은 중국 고전 희곡이 지닌 가치와 가능성을 발견하는 동시에 이웃 나라 연극에 대한 이해를 더해준다는 점에서 유의미한 시도였다. 또한 왕효응 연출이 서양과의 문화교류 무대에 동양의 고전희곡을 접목시켰다는 점에서 의미를 부여할 수 있을 것이다. 본 글은 선행연구를 바탕으로 하되, 아직 거의 다루어지지 않았던 서사구조적 연출 기법에 대해 주목했으며, 두 각색작의 구조적 연출 기법을 분석하여 극의 의미창출, 비극성의 증폭, 그리고 내면적 구조의 형성 등을 비교했다. 구체적으로 말하자면, 본 글은 먼저 원작의 서사구조 구성과 두 편의 각색작의 플롯 변화에 대해 분석하여, 이를 바탕으로 구조형식적 특징인 반복적 서사구조의 다양한 사용이 어떤 새로운 의미를 부여했는지, 또한 비극성의 증폭에 어떤 영향을 미쳤는지를 분석했다. 그리고 두 각색작에서 모두 사용된 히든 캐릭터에 주목하여 그들의 삽입이 원작의 구조에 입체적인 내면적 구조를 더하는 양상을 살펴보았다.

Visual Sentiment Analysis with Network in Network

Zuhe Li,Yangyu Fan,Fengqin Wang 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.9

In modern society, visual content like images and videos is increasingly becoming a new form of media to express users’ opinions on the Internet. As a complement to textual sentiment analysis, visual sentiment analysis intends to provide more robust information for data analytics by extracting emotion and sentiment toward topics and events from images and videos. Inspired by recent works that applied deep convolutional neural networks (CNN) to this challenging problem, we proposed a framework for image sentiment analysis with a novel deep neural network called Network in Network (NIN) which intends to improve the discriminability for local patches within receptive fields. We trained our network on a dataset consisting of nearly half a million Flickr images and minimized the effect of noisy training data by fine-tuning the network in a progressive manner. Extensive experiments conducted on manually labeled Twitter images show that the proposed architecture performs better in visual sentiment analysis than conventional CNN and other traditional algorithms.
