This paper presents methodological and theoretical principles for constructing a machine thanslation system between Korean and Japanese. We focus our discussion on the real time computing problem of the machine translation system. This problem is characterized in the time and space complexity during the machine translation. The NARA system has the real time computing algorithm which is based on a mathematical model integrating the linguistic competence and the linguistic performance of both languages, with consequence that the system NARA has also the functional characteristic : the two-way translation mechanism.

퍼지제어기는 입.출력 관점에서 일반적으로 입.출력에 대한 비선형 함수로 볼수 있다. 전문가의 제어 행위의 입.출력 관계가 크리시(crisp) 비선형 함수로 표현되었을때 그것을 언어적 퍼지 모델링(linguistic fuzzy modelling)하는 방법이 1-입력/ 1-출력 및 2-입력/1-출력의 static 시스템에 대하여 제안되었다. 이를 위해 소속함수 제한조건(membership function constraint)의 개념을 제시하고 선형계획법에 의한 최적화 기법을 이용하여 소속함수의 생성에 관한 체계적인 방법을 제안한다.

The main purpose of this study was to develop fuzzy models in order to decide system failure rate in industrial accident prevention. The purposed linguistic approach uses the Zadeh's concept of a linguistic variable with value which are not number. The problem of measurement Is the assignment of numbers to reprresnt properties of the involved events, object, or situation. Thus, in this study, part standard compatibility function was used.

This paper aims to describe a German-Korean machine translation system for nominal phrases. Besides, we have two subgoals. First, we are going to revea linguistic differences between two languages and propose a language-informational method fo overcome the differences. The method is based on an integrated model of translation knowledge, efficient information structure, and concordance selection. Then, we will show the statistical results about translation experiment and its evaluation as an evidence for the adequacy of our linguistic method and translation system itself.

The objective of this study, which applies the multiple-disciplinary approach to the developmental characteristics of children, is to study and develop a class model that can be applied to actual kindergarten classes in rural area. For this purpose, this study proposes teaching and learning methodologies for children based on English children's tales to help make the English education of children more effective and efficient. Based on the findings, the following suggestions should be considered for improving the English-education class model for kindergartners for rural areas: First, various activities based on the multiple-intelligence approach are important methods of children-oriented education advanced by the Sixth Children's Curriculum, helping children grow their independence and creativity. Second, various activities developed by this study on the basis of the multiple-intelligence approach to promote children's reading, listening, speaking, and writing abilities helped children improve their linguistic capacities, improve creativity, and remain motivated, which was reinforced by the differences found between the test group and the control group.

In recent years, there have been a number of applications of fuzzy logic in fuzzy reasoning system. The main objective of these applications is to approximate a decision making using the fuzzy reasoning system. This paper designs a fuzzy reasoning model for the decision making of registration fee at a private school, implements it applying for linguistic variables and fuzzy rules, and evaluates the practical availability of the model. The system accepts fuzzy rules, the type of membership functions, the domain of fuzzy sets and hedge, and fuzzifies the linguistic variables to generates fuzzy sets. The fuzzy sets generated are combined to constructs a solution fuzzy set. Finally, the system defuzzifies the solution fuzzy set to calculate a scalar value which is used for decision making.

This paper presents and adaptive fuzzy controller using fuzzy neural networks(FNNs). The adaptive controller uses two FNNs. One FNN is used to identify a fuzzy model of controlled object. The other FNN is used as a fuzzy controller. The fuzzy controller is designed with the linguistic rules of the fuzzy model. The response of the designed control system is checked with a linguistic response analysis proposed by the authors. An adaptive tuning of the control rules of the FNN controller is made possible utilizing the fuzzy model. Simulations using nonlinear controlled objects were done to verify the proposed control system.

This study aims to establish ways of how languages are used as determination factors for investment decisions among Asian countries where used languages are diversified. According to the analysis result, language segmentation of the investing country increases investment whereas the language segmentation of the invested countries is analyzed as the decreasing factor of investment. Also, it is analyzed that the further the linguistic distance between the investing country and the invested country the more investment increases. In the aspects of approached language distance and investment time selection, along with the increased linguistic distance, the elasticity to foreign direct investment is apprehended to be more flexible than other forms of investment. Such result shows the more segmented the languages of the targeted invested country the more investment cost will increase and therefore the results in linguistic distance can be explained as diversification of the invested country and the result to the forming of bridgehead at the invested area.

This paper takes issue with the idea of language as a 'serial-time structure' as opposed to the 'real-time event' of speech, an idea entrenched in Chomskyan model of linguistic theory. The discussion centers around the leitmotif question: Is language constructed entirely from a finite set of apriori discrete symbol types, as the 'competence vs performance' dichotomy implies\ulcorner A set of linguistic patterns examined in this study, largely with regard to phonological considerations, points to the evidence to the contrary. That is, while the patterns may be said to be linguistically distinct, they are not discretely, different, i.e. not different enough to be reliably differentiated. It is demonstrated that much of current research in phonology, including the most recent Optimality Theory, is misdirected in that it falsely presupposes a discrete universal phonetic inventory. The main thrust of the present study is that there is no sharp boundary between 'competence' defined as the formal, symbolic, discrete time domain of language and human cognition on the one hand and 'performance' as the continuous, fuzzy, real-time domain of human physiology on the other.

기존의 전문 검색 시스템은 문서를 단지 단어의 연속이라는 제한적 관점에서만 바라보았다. 또한 기존의 필드 검색 시스템은 고정된 필드를 색인 및 검색대상으로 하거나, 문서의 내용이 아닌 메타 정보에 관한 검색만이 가능하였다. 본 논문에서는 내용과 필드 구조를 통합하여 가변 필드 구조 문서를 색인 및 검색하는 모델인 교차 필드 검색 모델을 제안한다. 기존 정보검색 시스템의 기능을 기본으로 제공하면서 필드구조를 색인/검색하기 위한 기능적 요구사항을 제시하고, 내용 및 필드 구조를 색인하면서 동적인 삽입/삭제가 가능한 색인 구조를 제안한다. 아울러 검색시에 문서 가중치를 계산하여 문서를 순위조정하는 불리언 모델, 확장 불리언 모델, 벡터 공간 모델의 변형 모델을 제시한다. 아울러 구현 사례로 STEER-XDS 검색 시스템에 대해 알아본다.
