This paper attempts to provide the syntax and semantics of the so-called 'double subject constructions' in Korean, within the framework of Generalized Phrase Structure Grammar, introduced in works such as Pullum (1982), Pollard (1984, 1985a,b), Gazdar, Klein, Pullum & Sag (1985), and Ik-Hwan Lee (1985a, b). In particular, the present paper discusses the types of sentences exemplified in (1) and (2). (1) Cheolswu ka meli ka coh ta. SP head SP good DP 'Cheolswu is bright.' (2) Cheolswu ka Mica ka coh ta. SP SP good DP 'Cheolswu is fond of Mica.' Notice that in (1), and similarly in (2), the two NP's are marked by the subject case particle. In order to account for this construction, several analyses have been proposed within the tradition of generative grammar, and recently altanative analyses have been proposed in the framework of GPSG. This paper examines several previous analyses, and notes important problems in them. In order to resolve the noted problems; the present paper subcategorizes adjectives such as cho 'good' into intransitive adjectives and transitive ones. This distinction has an important semantic consequence. Furthermore, for the constructions such as (1), an abstract discourse predicate (DSP) is postulated and its translation is appropriately provided. To conclude, it is hoped that the paper has shown the effectiveness of GPSG, with the suggested revision and extension, in a proper treatment of double subject constructions in Korean.

어휘의 사용과 의미 구조

Language has been viewed as communicating meanings through the medium of concepts. On this view, each lexical item is associated with a concept Knowing a ward involves various kinds of word knowledge. Increasing knowledge of one word knowledge aspect could help improve knowledge of related aspects. The different kinds of word knowledge are interrelated. Frequency is related to formality in that more frequent words tend to be less formal, and tend to be more formal. Thus, greater awareness of formality is likely to be somewhat related to awareness of a word's frequency of occurrence, even if this awareness is unconscious. Words have a core meaning that is relatively universal and is likely to be acquired before other figurative meanings, prototype theory has been developed to explain how people deal with fuzzy meaning. The theory proposes that the mind uses a typical "best example" of a concept. This paper surveyed some of the important research findings about meaning organization and register knowledge. Register is a complex set of informations that is affected by many different factors. Register is connected with the paradigmatic issue of getting things done with language. This paper also examined association research that indicates the nature of meaning organization. Word association studies suggest that words are organized in the mind. This organization changes as one matures or as one's language proficiency increases.

균등 변환을 이용한 고속 프랙탈 영상 부호화

Image compression based on fractal theory is known to have high compression rate and fast decoding time. However, it is limitedly used in practice since it spends too long time to find matching blocks in encoding process. In other to reduce the encoding time we propose a new method to reduce the number of comparisons using the isometry transformation. The proposed method classify the blocks into one of four types such as plain, middle, vertical/horizontal, or diagonal block. The block search time can be reduced by applying the 8 isometry transformation process in different ways depending on the block types. The experiments show that the proposed method reduces the compression times up to minimum 35% smaller than those of 8 isometry transformations while maintaining PSNR of 27∼30dB.

The damage of the pressure courage by degradation can become the reason of unexpected break down or failure accident and it is very important because safety accident, the production loss, environmental pollution, social problems are occur. Consequently The result to investigat of failure accident for domestic pressure vessel, the factor of degradation is SCC, Sorrosion, Cavity, Crack

영어의 수동구문과 문태규 문법

This paper attempts to provide a syntactic and semantic analysis of passive operations in order to provide a proper treatment of the various types of passive constructions in English. In section 2, it is argued that one syntactic rule of passive is not sufficient. In section 3, the phrasal type of passive rule is critically examined. It is argued that a lexical rule, as well as a phrasal rule, is necessary. In section 4 and 5, two types of passive rules are formalized under the framework of Montague grammar, taking the previous formalizations into consideration. The formulated rules are illustrated with appropriate examples showing detailed syntactic delivations and accompanying translations. In sections 6 through 8, several problematic examples are examined and suggestions are provided for an approriate treatment of the examples. It is concluded that two types of rules are necessary for a satisfactory account of the passive constructions in English.

카오스 신경회로망을 이용한 카오스 동기화

In this paper, chaotic synchronization in chaotic neural network and its possible application to secure communication are discussed. Toshimitsu Ushio has recently shown that it is possible to synchronize one-dimensional chaotic neural networks with uni-directional connection using feedback control. Thus we designed chaotic synchronization with three neurons connection using successive and simultaneous synchronization. These chaotic synchronization concepts are useful for applying to speech private communication system. In the experiment, we demonstrated the mutual chaotic synchronization and speech signal modulation and recovery in the spread- spectrum-communication.

Collocation refers to combinations of two lexical items which make a semantic contribution to discourse. According to the analysis of collocations in English, words do not combine randomly but follow rules and principle. A major direction in vocabulary studies today is researching multiword units through corpus evidence to establish their frequency and behavior. Lexis should not be considered as individual words in isolation but should be viewed as integral part of discourse. This phenomenon is one of the most important trends in vocabulary studies. Some studies show that collocational or idiomatic meanings are processed faster than literal meanings. This may be seen as evidence that fixed expressions are stored and retrieved as single words. Chunking may facilitate language learning process. Multi-word units are so common in normal language that they may well be the basic organizing principle in language production. They are certainly known to the vast majority of native speakers. In general, studies of collocation focus on more on their formal properties and collocations provides stylistic variety and lend emphasis to statements. The functions of collocation can be classified according to the way in which they contribute to the content and structure of a text. In some aspects, lexis is closely related with grammar, meaning and phonelogy. In other respects, lexis is independent of the above three areas. It can be said that lexis has relation with the three fields. The ability to use collocations in English effectively will lead to the enhancement of communicative competence by learners of English.

객체 지향 개발을 위한 OMT 동적 모델 개선에 관한 연구

Statecharts is usually used as the specification model for dynamic model and reactive system, Statecharts is a superior computation model, but aspect of data is expressed by global variables and side effects to them, so the readability is lower when we describe larger systems in Statecharts. Moreover state structure in Statecharts is less relevancy to structure of object model. In this paper we propose the specification model OMT++. In OMT++, dynamic model is described with the structure of object model, which have more relevancy to structure of object model and more locality caused by making each object have state transition diagram and data. We show the prosperity of OMT++ through examples, and compare with Statecharts, and give operational semantics of OMT++.

본 논문에서는 카오스 현상을 나타내는 수식을 변형하여 암호시스템이나 PN(pseudo-noise)시퀀스에 적용하기 위하여 복잡한 카오스 신호를 발생시키는 하이퍼카오스 VP사상(HVPM, Hyper chaos Volume Preserving Maps)과 이들간의 카오스 동기화를 제안한다. 단계별 모듈러(modulus)함수를 이용하여 랜덤한 카오스 신호를 발생시키기 위하여 이산시간(discrete-time) HVPM 모델을 설정하고, 수치해석 실험드로 아날로그 카오틱 시퀀스(CAS. chaotic analong sequence)의 특징을 분석한다. 그리고 HVPM의 신호를 기존의 단순한 PC(Pecora, Carroll)방법을 응용한 치환동기화 (synchronous substitution)를 이용하여 구동 및 응답시스템간의 카오스 동기화(chaos synchronization) 제어를 한다. 수치실험에서 카오스 신호가 갖는 특징들을 확인할 수 있었으며, 치환동기시스템에서 효과적인 카오스 동기화가 수행됨을 증명할 수 있었다.
