Discourse analysis is useful for examining discourse characteristics of dementia patients and differentiating them from normal adults. However, inconsistent tasks, transcription methods and measures have been utilized, thus analyses were inevitably unsystematic. The purpose of this study was to investigate tasks, transcription methods and measures of discourse studies in dementia. Studies on dementia discourses written in English were collected via Scopus database containing abstracts and citations from 2005 to 2014, and were analyzed in detail. From the results, the most frequently used task was 'storytelling-topic'. It was observed that use of consistent transcription conventions rendered more reliable transcription data. Measures could be categorized into coherence, cohesion, productivity, propositional syntactic lexical analysis, and fluency, and each category belonged to discourse processing levels (i.e., processing of conceptual networks, propositions, and natural language units). In conclusion, future research warrants not only utilization of discourse tasks depending on dementia types and features, but also application of consistent transcription conventions. Additionally, measures based on the discourse processing theory would enable us to systematically interpret discourse studies.

This study undertook a methodological investigation on previous research that had proposed alternative methods for analyzing argumentative discourse in science classes in terms of collaborative construction and epistemic enactments of argumentation. The study also proposed a new way of analyzing argumentation discourse based on the achievements and limitations of previous research. The new method was applied to actual argumentation discourse episodes to examine its feasibility. For these purposes, we chose the studies employing Toulmin's argument layout, seeking for a method to analyze comprehensively the structure, content, and justification of arguments, or emphasizing evidence-based reasoning processes of argumentation discourse. In addition, we contrived an alternative method of analyzing argumentative discourse, Discourse Register on the Evidence-Explanation Continuum (DREEC), and applied DREEC to an argumentative discourse episode that occurred in an actual science classroom. The advanced methods of analyzing argumentative discourse used in previous research usually examined argument structure by the presence and absence of the elements of Toulmin's argument layout or its extension. Those methods, however, had some problems in describing and comparing the quality of argumentation based on the justification and epistemic enactments of the arguments, while they could analyze and compare argumentative discourse quantitatively. Also, those methods had limitations on showing participants' collaborative construction during the argumentative discourse. In contrast, DREEC could describe collaborative construction through the relationships between THEMEs and RHEMEs and the links of data, evidence, pattern, and explanation in the discourse, as well as the justification of arguments based on the flow of epistemic enactments of the argumentative discourse.

This study aims to provide a cornerstone for 'Pedagogical Discourse Analysis' by connecting linguistic theory to science education practice. Pedagogical Discourse Analysis (PDA) focuses its attention on finding educational implications beyond description on classroom language. This study is specially aimed at PDA in terms of the textual aspect, which has not sparked interest in science classroom discourse. For this, we supposed that the framework of PDA composed of two axes: 'thematic flow' and 'information flow'. We presented a case of science classroom discourse in terms of PDA to investigate opportunities in its potential and utilities. This trial crosses the line of traditional science classroom discourse analysis, which has been inclined to linguistics theory. It will also suggest a new horizon for science classroom discourse in an educational context.

This paper tried to analyze Starcraft's multiplay by using especially Greimas's theory of discourse. Greimas's theory of semiotics is known as a useful tool of analyzing non-verbal text as well as verbal text. The discourse of Starcraft is continuously made by subject and anti-subject. This characteristic of discourse- not given completely made- is the prominent difference from discourses made from other media. The subject and anti-subject, as actively crossing the position of enunciator and enunciatee each other, dynamically make and complete the discourse.

본 논문은 과거 많은 학자들에 의해 제기된 주구조와 부구조, 하위구조 등의 담화 내 계층적 구조에 대한 증거로 일탈을 중심으로 부구조를 분석하였다. 먼저 주제 일탈의 구조와 정의에 관해 분석하고 중단과 화제 전환 등과의 차이를 설명하였다. 지식 표현 언어인 Sowa의 개념구조론의 체계 내에서 담화의 계층적 구조와 그 구조를 나타내는 언어적 표시인 담화 표지의 예를 기술하는 방법을 제시한다. 개념 관계로 일탈, 화제 전환, 틀의 관계를 설정하여 담화 내 계층구조와 담화 부분과의 화용적인 관계를 규명하였다. 기존의 개념구조론은 선택적 제약, 조응 등의 의미론적인 개념들을 간결하고 정확하게 기술할 수 있었는데 화용론적인 측면의 기술도 가능함을 보여준다.

본 연구에서는 한국어 대화체에 사용되는 담화표지와 부 대화의 유형을 분석하였다. 한국어 대화체에 사용되는 각종 담화표지에 대한 기존의 언어학적 연구를 정리하였고, 실제 한국어 대화자료를 녹취, 전사하여 연구에 필요한 데이터를 만들었으며, 이 데이터를 분석하여 한국어 대화체에서 관찰되는 부 대화의 유형을 분류하고자 하였다. 또한 각 부 대화와 담화표지들간의 관계를 규명하려는 시도를 하였다. 이것은 인간과 컴퓨터간의 특정 목적 대화를 구현하는 데도 중요한 역할을 한다. 특히 인간과 컴퓨터가 예약, 상담 등 특정 목적을 달성하기 위한 대화를 수행할 수 있는 프로그램을 구축하는 데 있어서, 인간이 실제로 사용하는 담화표지 및 의사소동 책략 등을 반영할 수 있게 해줄 것이다. 담화분석 연구자들이 실제 대화 자료를 분석하여 한국어 대화체의 기저에 흐르는 대화의 메카니즘을 다방면에서 종합적으로 정리하면 그 결과를 토대로 전산학 연구자들이 한층 바람직한 한국어 대화인지 모형을 만들어낼 수 있을 것으로 기대된다.

The aim of this study is to observe the trend of discourse study in language education and analyze the main issues by investigating the literatures related to discourse in Korean language education in the last ten years. This study observed the discourse study conducted in Korean language education from the perspectives of study subject, study method and study data. Moreover, based on the results, it estimated the achievements and effectiveness of the discourse study conducted in Korean language education. The subject of discourse study was mainly dealt with discourse function, discourse pattern, discourse marker, discourse structure. In the study methods, analysis of corpus and survey were mainly used as the study methods, and spoken corpus, written corpus and semi-spoken corpus were used as study materials. In particular, the semi-spoken corpus was used at a very high rate among them. This showed that discourse study in Korean language education was mainly focused on spoken corpus study. This study divided the detailed field of Korean language education into four fields of linguistic knowledge, communication function, teaching activities and learning activities, and observed the trends of discourse study in each field. Overall, it was recognized that relatively many studies were focused on linguistic knowledge, particularly in pragmatic perspective. It can be said that the study based on discourse has a language educational effectiveness in that it is based on actual data and improves practical communication skills in the environment of various languages.

Argumentation is a social and collaborative dialogic process. A large number of researchers have focused on analyzing the structure of students' argumentation occurring in the scientific inquiry context, using the Toulmin's model of argument. Since SSI dialogic argumentation often presents distinctive features (e.g. interdisciplinary, controversial, value-laden, etc.), Toulmin's model would not fit into the context. Therefore, we attempted to develop an analytical framework for SSI dialogic argumentation by addressing the concepts of 'discourse clusters' and 'discourse schemes.' Discourse clusters indicated a series of utterances created for a similar dialogical purpose in the SSI contexts. Discourse schemes denoted meaningful discourse units that well represented the features of SSI reasoning. In this study, we presented six types of discourse clusters and 19 discourse schemes. We applied the framework to the data of students' group discourse on SSIs (e.g. euthanasia, nuclear energy, etc.) in order to verify its validity and applicability. The results indicate that the framework well explained the overall flow, dynamics, and features of students' discourse on SSI.

담화 구조를 파악하기 위한 대표적인 방법으로 Litman과 Allen 의 계획 기법에 의한 것과 RDTN을 이용한 것을 들 수 있다. 그 중에서도 RDTN을 이용하여 대화의 흐름을 파악하려는 시도는 간단하며, 결정적이라는 장점이 있는 반면에 몇 가지 단점도 가지고 있다. RETN을 이용한 대화 분석의 가장 큰 단점은 정확히 분석된 화행을 입력으로 사용한다는 것이다. 즉, 현 상태에서 다음 상태로의 전이에 정의된 화행 이외의 화행이 입력으로 사용되면 분석을 실패하게 된다. 또 하나의 단점은 RDTN 이 어느정도 영역에 의존적인 특성을 보인다는 것이다. 본 논문에서는 이러한 확장성에 대한 문제점을 해결하고, 화행 분석의 어려움을 덜기 위해 신경망을 이용한 새로운 대화 전이망을 제안한다. 제안된 대화 전이 신경망은 지역적 대화 전이 신경망과 전역적 대화 전이 신경망은 이전의 두 발화와 현재 발화와의 관계를 살펴서 현재 발화가 이전 대화의 연속인지, 새로운 대화이 시작인지, 아니면 부대화의 시작인지를 결정하는 역할은 한다.전역적 대화전이 신경망은 담화 스택과의 상호 작용을 통해 담화의 전체구조를 살피고,전체 담화 구조에서 현재 발화가 어떤 역할을 하는지를 결정한다.
