Using mother tongue in English classroom is controversial. Native speaking instructors seem to be for English-only classes whereas many Korean teachers of English feel it's effective to conduct classes in Korean especially for explaining usages and functions of certain grammar or new vocabulary. In fact, many studies have supported using mother tongue. However, excessive use of it hinders students from practicing the target language. Obviously it doesn't necessarily have to be all or nothing system. The study shows the positive role of mother tongue in written form based on the results of the students' academic performance at Chung-Ang University's summer program 2000. The results indicate that using mother tongue in written form helps beginning level students understand grammar and vocabulary more effectively, leads them to do better on tests than those of English-only class, and encourages them to actively get involved in class discussion and responses.

The purpose of this paper is to make a sentence systemic within the category of structural grammar for the modality in which a speaker expresses his attitude. It is the priority of a language to communicate meaning. By eliminating the theoretical description of traditional grammar, this paper also aims to illustrate the concepts of nine modal verbs through a systemic network. The concept of modality includes both the epistemic and the deontic characteristics of modality. Epistemic modality is associated with either knowledge or belief on the part of a speaker who gives his own judgments about the state of affairs, events, or actions. However, deontic modality is related to either the possibility or the necessity of acts that a speaker performs to give permission or fulfill an obligation. In conclusion, all the subsystems are described within the framework of the systemic network, with the intention of including all the potential options of the semantic functions available in a situation.

구문태그가 부착되지 않은 코퍼스를 사용하여 문법규칙의 확률을 훈련하는 비통제 학습(unsupervised learning) 방법의 대표적인 것이 CNF(Chomsky Normal Form)의 CFG(Context Free Grammar)를 입력으로 하는 inside-outside 알고리즘이다. 본 연구에서는 의존문법을 CNF로 변환하는 기법에 대해 논하고 의존문법을 위해 변형된 inside-outside 알고리즘을 논한다. 또한 이 알고리즘을 사용하여 실제 훈련한 결과를 보이고, 의존규칙과 구문구조 확률을 같이 사용하는 hybrid방식 구문분석기에 적용한 결과를 보인다.

Negative polarity items(NPIs), which function as quantifiers are licensed in a syntactically strict way by negatives, which function as qualifiers, resulting in universal negating interpretations as pairs. We present a proposal to explain the related phenomena, in which the syntax and the semantics are closely related to each other, with Combinatory Categorial Grammar. For this purpose, we first adopt the usual approach to scrambling, but control its overgeneration with the use of markers, taking into account the complex syntactic phenomena involving NPIs and scrambling in Korean. We also propose to utilize polarity intensity as a novel feature, in order to account for the universal negating interpretations when NPIs are combined with negatives. Our proposal also explains the difference in readings when other quantifiers or qualifiers intervene the NPI and the related negatives.

Relativization is one of the common syntactic operations to merge two different clauses into a single information unit. This operation plays a pivotal role to structuralize multiple clauses cohesively as well as serves to specify the property an individual has within the context. That implies that relativization contributes to information structure of multiclausal sentences. In this context, this paper delves into information structure of relative clauses in English with an eye toward creation of a computational model from a standpoint of machine translation. The current work employs Head-driven Phrase Structure Grammar (HPSG, Pollard and Sag (1994)) as a theory of grammar and Minimal Recursion Semantics (MRS, Copestake et al. (2005) as a meaning representation system. Building upon these formalisms, this paper addresses how information structure of relative clauses can be represented and constrained. The current work makes use of Individual CONStraints (ICONS) for modeling relative clauses with respect to information structure. The current work also investigates which relative clause involves which information structure constraint. The present study argues that non-restrictive relative clauses impose a more specific constraint on information structure than restrictive relative clauses.

격현상은 한국어의 여러 가지 문법현상들을 분석하고 이를 전산학적으로 구현하는데 아주 중요한 부분 중의 하나이다. 결합범주문법(Combinatory Categorial Grammar; CCG)을 이용한 대부분의 기존 연구들에서는 격조사나 보조사들에도 별도의 통사범주들을 할당한 후, 이들 조사들이 명사와 결합하여 하나의 명사구를 구성하는 것으로 조사들을 처리하고 있다. 그러나 이러한 방법들은 이론적인 문제점들뿐만 아니라 전산적 구현에 있어서도 문제점을 안고 있다. 본 논문에서는 이러한 문제점들을 해결하면서도 한국어의 격현상을 효과적으로 구현할 수 있는 방법을 소개한다. 본 논문에서 사용하려고 하는 문법공학 시스템은 한국어를 위한 유형상속 결합범주문법(Type-inherited Combinatory Categorial Grammar; TCCG)이다. 이 시스템 안에서는 명사구의 격조사나 보조사들이 별도의 통사범주들을 할당받지 않고, 명사의 굴절규칙(inflectional rules)에 의하여 명사와 결합하게 된다. 따라서 국어의 기본적인 격조사들을 효율적으로 구현할 수 있을 뿐만 아니라 보조사나 격조사 탈락현상들도 효과적으로 분석하고 구현할 수 있게 된다.

'过' and '了' are the key points, as well as difficult ones, in the academic study of Chinese grammar and language teaching. This article analyzes this language use by taking two sentence structures as example, namely 'Pao le.' and 'Pao guo le.'. As the semantic meanings of 'V+了2' and 'V+过1+了2' are very similar. Therefore, it can be confusing for non-native speakers to master this usage. This article attempts to sort out and analyze the usage environment and pragmatic characteristics of 'V+过1+了2' by employing the examples from the data of Corpus of the Chinese Linguistics Research Center of Peking University. By focusing on the usage environment and pragmatic characteristics of '过' and it is desirable for teachers to combine semantics, syntax and pragmatics while explaining the grammar point, in order for learners to understand accurate information quickly and learn how to use it.

This study began with the lack of use of native Chinese professors in universities despite the fact that native Chinese professors are present and can provide a high-quality language environment to improve foreign language skills. In the literature, most team teaching studies were limited to speaking or cultural classes, and to apply a new teaching method called team teaching to Chinese grammar classes, they designed a class model and presented class guidance with an example of research 'le' In order to satisfy learners'desire for knowledge and to develop the Chinese teaching field, it is necessary to develop various teaching methods, and there should be various meaningful attempts.

Programming novices have various difficulties when they learn C language for the first time. Novices have a large burden for understanding of a C language grammar, and have a tendency to focus on the grammar rather than problem solving. Moreover, it requires programming domains to arouse student's interest for software development. This paper presents a programming environment for C languages education focusing on a problem solving. To this end, this paper defines Tiny-VPL that is a simple visual programming language for NXT robot programming and presents robot programming environment using Tiny-VPL. This paper also presents an environment for NXT robot programming using Mini-C language which is a subset of C language. For the purpose of helping to understand the C syntax and semantics, the visual and interactive conversion system of Tiny-VPL to Mini-C is provided. Our programming environment can arouse student's interest through robot programming and can be used effectively for C language education focusing on problem solving with graphical and interactive conversion of the visual language Tiny-VPL to the textual language Mini-C.
