  • This study was carried out to analyze terms in primary science textbooks. The results of the research are as follows. 1. The higher-grade science textbooks use more types of categories and less definitions for terms. Only 14% of definitions for terms are showed in textbooks, and no more than 0.4~0.6 definitions shows the shortage of definitions for terms in one class content. 2. The definitions by contract, which forms 68%, was the highest in elementary science textbooks. And the dictionary definitions, which are 62%, was the highest in experiment-observation textbooks. 3. The most used type of definitions is the way which is used for a case or a indicating methods, and its rate is increasing steadily. And its rate was 76% of the whole of terms. 4. Terms used in energy field are few as compared with terms of other fields. Each field has completely different ways of defining terms and presenting content in textbooks to other fields.

  • VSField-associated term is a single or compound word whose terms occur in any document, and which makes it possible to recognize a field of text by using common knowledge of human. For example, human recognizes the field of document such as or , a field name of text, when she encounters a word 'Pitcher' or 'election', respectively We Proposes an efficient construction method of field-associated terms (FTs) for specializing field to decide a field of text. We could fix document classification scheme from well-classified document database or corpus. Considering focus field we discuss levels and stability ranks of field-associated terms. To construct a balanced FT collection, we construct a single FTs. From the collections we could automatically construct FT's levels, and stability ranks. We propose a new extraction algorithms of FT's for document classification by using FT's concentration rate, its occurrence frequencies.

  • This empirical study investigated the effect of choice of record field(s) upon which to search on retrieval performance for a large operational bibliographic database. The query terms used in the study were identified algorithmically from each target set in four different ways: (1) controlled terms derived from index term frequency weights, (2) uncontrolled terms derived from index term frequency weights. (3) controlled terms derived from inverse document frequency weights, and (4) uncontrolled terms based on universe document frequency weights. Su potable choices of record field were recognised. Using INSPEC terminology, these were the fields: (1) Abstract. (2) 'Anywhere'(i.e., ail fields). (3) Descriptors. (4) Identifiers, (5) 'Subject'(i.e., 'Descriptors' plus Identifiers'). and (6) Title. The study was undertaken in an operational web-based IR environment using the INSPEC bibliographic database. The retrieval performances were evaluated using D measure (bivariate in Recall and Precision). The main findings were that: (1) there exist significant differences in search performance arising from choice of field, using 'mean performance measure' as the criterion statistic; (2) the rankings of field-choices for each of these performance measures is sensitive to the choice of query : and (3) the optimal choice of field for the D-measure is Title.

  • Field-associated Terms itself have field Information. So, they determine field of document just like when human being perceives field. In case of Korean, we organized and experimented them by collecting approximately IS,999 document banks that are classified into 180 fields. We obtained high precision of extraction that 88,782 single field-associated terms are contracted into 8,405 ones thus recording compression rate as approximately 9$\%$ and recall as above 0.77 (average 0.85), precision as above 0.90 (average 0.94). By applying established field-associated terms to initial determination for document classification and comparing it with filed determination by human being, we got correct answers above approximately 90$\%$. We can use results of research as fundamental research for initial stage and apply it document retrieval between multilingual environment thus utilizing it as fundamental research for multilingual information retrieval.

  • The purpose of this study was to clarify the origin which have misused terms, analyze Its meanings and suggest the unified terms. The content of this study are as follows. The origin of the terms in western dress is different with the areas of cultural influence. Japanese occupied much more than other languages in the apparel industry after the civilization. and English has dominated in the educational filed since 1945 the Liberalization. French, German, Portuguese, Spanish, Dutch are added. These languages came to the clothing field via Japanese and English or directly from the countries. 망토(manteau프), 메리야스(medias스), 러닝셔츠(일) 라사(raxa네), 오트 쿠튀르(Haute Couture 프), 비로드(veludo 포), etc. However the words of foreign origin have misused or corrupted until now a days. 마이 (재킷, 상의), 노 슬립, 소데나시 (슬리브리스, 민소매) 넌라쟈(브래지어), 노타이, 노타이샤쓰(오픈칼라 셔츠, 넥타이를 매지 않은 셔츠) 와이샤쓰(드레스 ttu츠), etc. And also these terms are confused in using because of the word's diversity, the different nationality, change of the marking rules, and the difference between the education and production field terms. On the others hand, this study explained the differences between western costume and Korean costume as the clothing manufacture terms were translated to Korean. bodice-길, collar, neckline-깃, belt, sash-(허리)띠 And then the untied terms were suggested through the comparison production field and educational area (including schools and institutes). lapel, 라펠(학교용어) (학원용어), 가에리 (일) (의류산업 현장용어), 아랫깃(통일어) By the way, this study involved the origin of and misused teams in sewing and presented the unified terms. 미까시 (X)-미 카에시(일) - 안단($\bigcirc$), 이새(X)―홈줄임 ($\bigcirc$) As the above , the characteristics of clothing terms which have misused are Japans,;e, corrupt Japanese, false reports foreign words via Korean, Japanese, compound words of Korean and Japanese, compound words of English and Japanese. And also the words of foreign origin in clothing had the following tendency in the marking system. There are ellipsis of form, sex, timber, grammatical case '-ing', '-ed' in adjective and long vowels express to short vowels. We can see this phenomena as the rule of curtailment labor.

  • As what exactly understands a meaning of mathematics terms, is a starting point of mathematical thinking, it plays a very important role in the mathematics learning. What understood mathematics terms which were defined here, includes not only the terms of comprising its definition, but also all of the understanding in context, situation, intention and purpose, which came to give its definition. Due to this reason, it needs to be examined how much students are correctly understanding about mathematics terms which appear in the texts, and to seek for its cause for the terms which are felt to be difficult. Accordingly, this study investigated into mathematics terms which are used for the field of geometry in the elementary school mathematics textbooks, and tried to analyze students' understanding level about each term.

  • The purpose of this research is to search for directions in engineering education development in a knowledge-based society in terms of 'engineering ethics educatio'. Engineering ethics education, having been recognized as an inter-disciplinary research field between engineering and philosophy, is a field that has been a major issue in countries that execute engineering education accreditation. And engineering ethics education has been a peculiar research field focused on EAC(Ethics across the Curriculum). Therefore, this study has deduced several results by critically reviewing the extant EAC-related literatures. First, accomplishments by various researchers that may well quoted as the leader of engineering ethics study and education or the educational achievements of Kanazawa Institute of Technology in Japan are considerably substantial. However, the EAC discussions thus far still raise numerous barriers and unsolved issues. Second, the discussion of EAC thus far comprehends limitations such as a shortage of the recognition of inter-disciplinary study in the field of education and insufficient participation by education majors. Third, the engineering and philosophy field experts who have been leading EAC discussions have been pursuing integrated education courses either consciously or unconsciously. Fourth, EAC discussions may expand by again illuminating the intent of integrated education courses in terms of 'education and the study of education', and this new facet can be summed up with a new term, EAL, which stands for 'Ethics across the Living.'

  • Korean geological terms were first used in Hoso dynasty (A. D. 699) and a catalogue of Korean minerals was published on the basis of the Japanese naming in 1915 as nearly 60 species. Korean geological nomenclature was published about 2000 terms in 1963. In recently year, Normally the leading language was English: equivalent were gives in Germany. Chinese and Japanese in the geological field and multitude of new terms. Although, Korean geological nomenclature were many complication of multilingual has become a traditional occupation of geologist and related field. The purpose of this reviews is to comparing about Korean naming and Japanese naming in the historical background, in addition to valid geological terms in Korean and Japanese synonyms.

  • With the change of the agricultural environment (increased rice production, decreased rice consumption, and rice production policies), converting paddy fields into upland fields is an increasing trend. In terms of conversion into upland fields, subsurface drainage is one of the most important factors for good field crop growth. This study evaluates the performance of a subsurface drainage culvert system in paddy fields and reclaimed lands. The obtained results are briefly summarized as follows: 1) After a comparative evaluation of several subsurface drainage culvert systems, including excavated subsurface drainage and non-excavated subsurface drainage types, type 3 (non-excavated, perforated drain pipe 50 mm, filter mat B50 cm, subsoiling 70 cm and culvert spacing 5 m) shows relatively high values among four types in terms of effectiveness (subsurface discharge capability) and economic efficiency (construction cost). 2) Type 3 has proven that it is suitable for design standards of discharge capacity through field tests performed in paddy fields (three sites: Gong-geom, Gae-san, Juk-san) and reclaimed lands (two sites: Gum-ho, Mi-am). 3) In the experiment of Sesamum indicum growth according to the existence of a drainage system, Sesamum indicum growth with a subsurface drainage culvert system had good value in terms of plant shoot and root length, shoot fresh and dry weight, and root fresh and dry weight).
