As a computational approach to literary criticism, the method of character network analysis has attracted attention. The character network is composed of nodes as characters and links as relationship between characters, and has been used to analyze literary works systematically. However, there were limitations in that relationships between characters were so superficial that they could not reflect intimate relationships and quantitative data from the network were not interpreted in depth regarding meaning of literary works. In this study, we propose an improved method of character network analysis through a case study on the play . First, we segmented the character network into a dialogue network focused on speaker-to-listener relationship and an opinion network focused on subject-to-object relationship. We analyzed these networks in various ways and discussed how analysis results could reflect structure and meaning of the work. Through these studies, we strived to find a way of organic and meaningful connection between literary criticism in humanities and network analysis in computer science.

본 논문은 예술양식으로서 영화가 지닌 문법들 중 서사가 배치되는 원리를 파악하고자 정량적 분석을 시도했다. 구체적으로는 영상에서 나타난 정보를 측정하여 서사를 추동하는 핵심 요인인 '갈등'을 정량적으로 분석했다. 본 논문은 서사를 이끄는 주인공과 그에 대항하는 상대주인공의 얼굴 면적을 단계별로 측정하고, 그것과 갈등 사이의 상관성을 분석했다. 얼굴 면적을 측정 대상으로 삼은 이유는 그것이 영화에서 갈등을 연출할 때 누구를 어떤 방식으로 연출했는지를 보여주는 지표이기 때문이다. 영화 속 갈등의 정량화는 서사 단계, 또는 특정한 갈등 구간을 객관적 수치에 근거하여 색인화하는 데에 적용될 수 있다. 또한 갈등을 기준 삼아 그래프 등을 통한 서사 시각화가 가능해지며, 영화 서사 연구에 전산적 비평을 도입하여 방법론의 다양화를 도모할 수 있다는 점에서 유의미하다.

The reliability/redundancy of structural system has become a serious concern among engineers and researchers after structural failures in Northridge and Kobe earthquakes. The reliability/redundancy factor, ρ, in current codes considers only member force and floor area and has received much criticism from dissatisfied engineers. Within a reliability framework. the redundancy is investigated for dual systems of primary shear walls and secondary moment frames and steel moment frame systems. Probabilistic performance analyses are carried out baled on nonlinear responses under SAC ground motion. The effects of structural configuration, ductilily capacity, 3-D motion, and uncertainty of demand verses capacity are investigated. Important redundancy-contributing factors are identified and a uniform-risk redundancy factor is developed for design. The result are compared with the p factor and its inconsistency is pointed out.

The plastic hinge method and the plastic zone method are extensively adopted in displacement-based elements and force-based elements respectively for second-order inelastic analysis. The former enhances the computational efficiency with relatively less accurate results while the latter precisely predicts the structural behavior but generally requires more computer time. The displacement-based elements receive criticism mainly on plasticity dominated problems not only in accuracy but also in longer computer time to redistribute the forces due to formation of plastic hinges. The multi-element-per-member model relieves this problem to some extent but will induce a new problem in modeling of member initial imperfections required in design codes for direct analysis. On the contrary, a force-based element with several integration points is sufficient for material yielding. However, use of more integration points or elements associated with fiber section reduces computational efficiency. In this paper, a new force-based element equipped with stress-resultant plasticity model with minimal computational cost is proposed for second-order inelastic analysis. This element is able to take the member initial bowing into account such that one-element-per-member model is adequate and complied with the codified requirements of direct analysis. This innovative solution is new and practical for routine design. Finally, several examples demonstrate the validity and accuracy of the proposed method.

In this paper we explore the emergence of the notion of compactness within its historical beginning through rigor versus intuition modes in the treatment of Dirichlet's principle. We emphasize on the intuition in Riemann's statement on the principle criticized by Weierstrass' requirement of rigor followed by Hilbert's restatement again criticized by Hadamard, which pushed the ascension of the notion of compactness in the analysis of PDEs. A brief overview of some techniques and problems involving compactness is presented illustrating the importance of this notion. Compactness is discussed here to raise educational issues regarding rigor vs intuition in mathematical studies. The concept of compactness advanced rapidly after Weierstrass's famous criticism of Riemann's use of the Dirichlet principle. The rigor of Weierstrass contributed to establishment of the concept of compactness, but such a focus on rigor blinded mathematicians to big pictures. Fortunately, Poincar$\acute{e}$ and Hilbert defended Riemann's use of the Dirichlet principle and found a balance between rigor and intuition. There is no theorem without rigor, but we should not be a slave of rigor. Rigor (highly detailed examination with toy models) and intuition (broader view with real models) are essentially complementary to each other.

The application of computer software into the linguistic analysis of texts proves useful to arrive at concise and authentic results from large data texts. Based on this assumption, this paper employs a Computer-Aided Text Analysis (CATA) and a Critical Discourse Analysis (CDA) to explore the manipulative strategies of positive/negative presentation in Orwell's Animal Farm. More specifically, the paper attempts to explore the extent to which CATA software represented by the three variables of Frequency Distribution Analysis (FDA), Content Analysis (CA), and Key Word in Context (KWIC) incorporate with CDA decipher the manipulative purposes beyond positive presentation of selfness and negative presentation of otherness in the selected corpus. The analysis covers some CDA strategies, including justification, false statistics, and competency, for positive self-presentation; and accusation, criticism, and the use of ambiguous words for negative other-presentation. With the application of CATA, some words will be analyzed by showing their frequency distribution analysis as well as their contextual environment in the selected text to expose the extent to which they are employed as strategies of positive/negative presentation in the text under investigation. Findings show that CATA software contributes significantly to the linguistic analysis of large data texts. The paper recommends the use and application of the different CATA software in the stylistic and corpus linguistics studies.

데스크톱 다큐멘터리는 카메라로 촬영하는 대신 인터넷 오픈 아카이브에서 검색하고 선택한 멀티미디어 콘텐츠를 재료로 컴퓨터 인터페이스 상에서 그것을 재조합하는 창작자의 멀티태스킹 과정 자체를 스크린 캡쳐 기술을 사용해 녹화하여 완성하는 새로운 다큐멘터리 양식이다. 본 논문에서는 뉴 미디어 환경에서 잠재적 아카이브를 데이터 베이스 내러티브로 전환하고, 영화적 미장센을 컴퓨터 미장인터페이스로 바꾸며, 의식의 흐름을 통한 큐레이션으로서의 창작 메커니즘을 통해 창작과 비평의 경계를 오가는 메타-시네마이자 뉴 미디어 아트의 실험적 시도로서, 주류 호러 영화의 새로운 혼성 장르적 시도로서, 극영화 창작의 새로운 방식으로서, 새로운 모큐멘터리적 시도로서, 그리고 창작과 비평의 경계를 오가는 비디오 에세이와 비평 영화의 새로운 양식으로서 2010년대를 기점으로 부상하고 있는 데스크톱 다큐멘터리의 개념과 유형 및 특성을 연구한다.
