In this paper, some terms of high school mathematics which read Chinese characters phonetically in Hangul are studied semantically. Nowadays, most terms of high school mathematics are terms of Chinese characters given the reading of them in Hangul alphabet. In such terms of Chinese characters, there are many loan-words from daily life and newly coined terms. Some such terms are examined in respect of meaningfulness and rule-ness. The degree of meaningfulness and rule-ness of loan-words from daily life are relative. Students seems familiar to loan-words usually, but it is difficult to know whether students seems to be familiar to loan-words or not. Degree of familiarity to a certain loan-word must be relative. In loan-words, there are such terms whose mathematical meaning is different from daily life meaning. Such terms are strong in rule-ness. Newly coined terms are strong in rule-ness. Students are not familiar to newly coined terms which are not used in daily life and have only mathematical meaning. In coining new terms using Chinese character, unit characters are related directly or indirectly to concept which unit characters want to express. So, It is possible to guess something unit characters want to express by investigating them. According to Vinner(1991), images can be evoked. But in case of reading Chinese characters phonetically in Hangul, it can not be guaranteed for Hangul mathematical terms to evoke images which the original mathematical terms evoked. To solve such problems semantic investigation of mathematical terms has been suggested. Through this process, transplanting images which the original mathematical terms evoked into Hangul terms are planned.

The purpose of this study was to compare rock descriptors used by students in two different task contexts and to suggest the characteristics of a task suitable for learning of rocks. Twenty-four 3^rd grade students were given descriptive and inferential tasks about three types of sedimentary rocks, and the rock descriptors used by the students were analyzed from a resources-based view (RBV) about students' conceptions. The result showed that the number of students using everyday descriptors to describe properties of the rocks and the frequency of using the everyday descriptors decreased in the inferential task. It was also revealed that the students using disciplinarily more appropriate descriptors were more likely to infer the process of rock formation in scientifically valid ways. By contrast, student inferences lacking scientific validity were mostly those that used everyday descriptors to express properties of the rocks. Based on these findings, it was concluded that inferential tasks would be suitable for student learning of rocks which is to be authentic to the essential features of earth science practices.

우리가 일상적으로 사용하는 말속에는 모호한 표현들이 많이 들어있다. 예를 들어, '젊다', '크다', '어느 정도' 등의 표현들은 정해진 값을 갖는 말들이 아니다. 가장 보편화된 RDBMS에서의 질의어인 SQL(Structured Query Language, 이하 SQL)은 데이터베이스에서 허용된 값, 즉 정량적인 값들에 대해서만 질의할 수 있도록 되어 있다. '젊은 여자' 혹은 '20세 정도의 여자'라는 질의는 할 수 없으며, '25세의 여자' 라는 식으로 정확한 질의만이 허용된다. 그러나 정보량이 급증하고 있고, 정보가 곧 힘이 되는 지금, 일반 사용자들도 데이터베이스에서 자신이 원하는 정보를 얻어 낼 수 있어야만 하게 되었다. 따라서 본 논문에서는 일반 사용자들도 데이터베이스에서 일상적으로 사용하는 단어(이하 자연어)로 질의를 할 수 있도록 하는 FSQL에 대해 논의하고자 한다.

Today, documents existing on internet by the development of communication network increase in number. And it is required the information retrieval system that can efficiently acquire the necessary information. Most information retrieval systems retrieve documents using a simple keyword or a boolean query of keywords. But, the method is not fit for novice users to use and has many difficulties than user's dialogue query from the viewpoint of convenience and precise understanding for query. So, this paper has an aim to suggest the method that will cope with above problems and to design and implement a meta query processing system for information retrieval using Korean dialogue sentences. The system implemented in this paper can generates a new boolean query for a given Korean dialogue sentence and resolve lexical ambiguities through morphological analysis, syntactic analysis and extension of query using thesaurus.

일상어는 한 사회의 모든 구성원이 쉽게 이해할 수 있고 사회생활에서 아무런 어려움이 없이 상호간에 의사소통을 할 수 있는 언어의 표현 수단이다. 이에 반하여 학술어는 각각의 전문분야에서 사용되고 있는 언어의 한 형태이다. 학술적 텍스트에서 나타나는 일반적인 특징은 글이 객관적이면서도 명확하게 기술된다는 점이다. 일반독자는 자주 사용되는 전문어휘를 통하여 학술적 텍스트를 가장 쉽게 인식할 수 있으며, 또한 텍스트의 구성에 있어서도 학술적 텍스트가 일반 텍스트와 다르다는 사실을 알 수 있다. 이 외에도 독일어에서는 일정한 문법적 현상들이 학술적 전문어의 요소로서 사용되고 있다. 예를 들면 삼인칭 단수, 부사구, 명사화 경향, 기능동사구의 선호, 수동구문 등등이 있다. 일반적으로 학술적 전문어에 자주 사용되고 있는 문법적 요소 중의 하나가 수동구문이다. 학술어의 요소로서 수동구문이 갖는 언어적 기능은 다음과 같다: 1. 수동구문에서는 일반적으로 행위자가 언급되지 않음으로써 사실이 객관적으로 표현되며, 동시에 행위자의 억제는 언어의 경제성에 기여한다. 2. 경우에 따라서 행위자가 표현될 때, 직접적인 행위의 주체를 나타내는 von-전치사구 혹은 매개체나 원인을 표현하는 durch-전치사구를 통하여 사건을 정확하게 기술할 수 있다. 3. 테마-레마 구조와 관련하여 살펴보면 문장구성 혹은 문장연결을 위한 표현수단으로도 수동구문은 활용된다. 4. 수동구문을 사용함으로써 문체상의 단조롭고 획일적인 점을 회피할 수도 있다. 본 논문은 이와 같이 수동구문이 지니고 있는 언어적 기능을 살펴봄으로써 학술적 전문어의 특징과 전문어를 이해하는데 기여한다.

This paper is written in order to research for the contents and expression of HanYongUn's Sijo. HanYongUn is very famous as monk and independent campaigner, modern poet in Korea. He wrote many kinds of literary works, for example, many modern poetry, modern novels, Sijo, Chino-Korean Poetry etc. It's very exceptional that he wrote a lot of Korean traditional Sijo and Chino-Korean Poetry. Because he was a many modern poet as same as modern novelist. So studying on his Sijo can help someone to understand the essence of HanYongUn's all literature. That's why I'm studying on HanYongUn's Sijo. The firstly, in aspect of the the contents of HanYongUn's Sijo, HanYongUn was expressing three kinds of themes, that is ideology, reality, daily life in his Sijo. The ideology consists of Buddhism and Confucianism and the reality is related with social conditions, the daily life is deeply connected with Nim. These features of his Sijo are different from his modern poetry and Chino-Korean Poetry which had a simple theme, for example, love with Nim, daily life. The secondly, in aspect of the expression of HanYongUn's Sijo, I studied the expression of HanYongUn's Sijo in three angles, that is, vocabulary and the developing of poet thinking, rhetorics. HanYongUn used essential words for expressing three kinds of themes effectively in his Sijo. And he was developing of his poet thinking by three steps in his Sijo. He applied several representative rhetorics to his Sijo, those are question and answer, exclamation, irony, distich etc. Even though I studied the characteristics of HanYongUn's Sijo in two aspects But there could be the other things to study about these kinds of theme. I might continue researching the other kinds of theme next time in the near future.

The list of words and the semantic structure that connects them have been important to the areas of psychology, psychoanalysis, linguistics, and education. Some researchers in constructivist perspectives of science education also have interests in the structure of science concepts expressed by science terminologies. The purpose of this paper was to investigate the test environment factors influencing the word association test as a method to identify students' semantic structures for science terminologies. We set up four variables that are possibly considered in recognizing a word as having scientific meaning. The four variables include: noticing whether stimulus words are science terminologies or not, presenting science terminologies and everyday words alternately, whether presider is science teacher or not, and whether students have learned the concepts or not. In comparing the test results of the experimental group and the control group, we have checked whether each variable influences the test result or not. Stimulus words included nine science terminologies containing both ordinary and scientific meanings, and subjects included 282 middle school students. The degree of recognizing science terminology as having scientific meaning was found to increase only when stimulus words were noticed as science terminologies. In the case of the remaining variables, there was no difference between the control group and the experimental group.
