The purpose of this article is to discuss about both historical progress and current situation of user instruction in Korean academic libraries. Emphasis was on identifying and analyzing the special features and limitations of user instruction from the viewpoints of library users as well as those of librarians. To the end, data were collected from three methods: the first tool was such major statistical sources as 'KERIS university library statistics system' and 'Research Reports' by the Korean Private University Library Association. The second was from the results of surveys and interviews with librarians from 20 university libraries. And the third was from the results of surveys with library users in two sample university libraries.

도서관을 찾는 사람은 늘고 있으나, 읽는 책은 베스트셀러에 한정됐다. <출판저널>이 '독서의 달'을 맞아 전국 도서관 사서들을 대상으로 도서관 이용자의 독서경향에 대해 설문조사한 결과, 교육환경의 개선과 IMF여파로 이용자 수는 증가했으나, 도서구입예산과 독서 프로그램 부족으로 도서관에서 이뤄지는 독서는 문학 등 특정 분야에 편중되고 있다는 사실이 밝혀졌다. 학생들의 대출 건수는 꾸준히 늘어 강화군립도서관만 하더라도 전체 대출의 55%가 학생이다. 다른 도서관도 사정은 같아 학생들이 하교하는 오후 시간대에 가장 이용률이 높다. 최근에는 실직인구가 늘면서 성인 남자의 이용률도 높아졌다. 오미순 사서(해운대도서관)는 "IMF 여파로 취업.창업 관련서의 이용률이 늘고 있으며 그 이용자 대부분은 성인"이라고 밝혔고 성은정 사서(부여도서관) 역시 "IMF사태 이후, 성인 남자들의 이용률이 높다"고 응답했다. 하지만 문제는 도서관이 보유한 책이 베스트셀러에 국한돼 다양한 독서가 이뤄지지 않는다는 점. 조사결과, 이용자들은 <아리랑>, <하늘이여 땅이여>, <남자의 향기>, <토지> 등을 많이 찾는 것으로 집계됐다. 심지어는 로맨스소설이나 무협소설이 청소년들의 읽을거리로 제공되는 실정. 사정은 특수도서관도 마찬가지다. 어린이도서관의 경우, 어린이.성인 모두 문학류를 많이 찾고 점자도서관의 경우, 전체대출 중 80%가 소설류다. 구본일 사서(강화도서관)는 "예산이 부족해 이용자들이 많이 찾는 베스트셀러를 중심으로 구입할 수밖에 없다"고 밝히고 "다양한 책을 갖출 수 있도록 도서구입비 확충이 시급하다"고 주장했다. 또 알맞은 독서 프로그램이 없는 점도 이용자들의 베스트셀러 편중현상에 한몫을 담당했다. 진재호 사서(광주도서관)는 "과거보다 독서생활화가 고조됐지만, 양서를 읽는 독서문화의 부족"을, 김선연 사서(어린이도서관)는 "유아시절부터 성인까지 자연스레 고전을 읽게 하는 제도적 장치의 확충"을 지적했다. 한편 월평균 대출권수는 대도시 지역의 경우 11,000-45,000권, 그 외 지역은 1,600-6,000권, 특수도서관은 어린이도서관이 55,000권, 전화나 우편으로 대출하는 점자도서관이 650권이다. 관내열람만 허용되는 사회과학도서관은 월평균 이용자가 7,676명으로 대학생.대학원생.교수 등이 전체의 68%를 차지한다.

Di-2-ethyl hexyl phthalate (DOP) and di-2-ethyl hexyl adiphate (DOA) were mixed with poly(vlnvl chlorides) [PVC] which have different degrees of polymerization (DP). Tensile strength, elongation, density, abrasion resistance, and hardness of these compounds were measured, High molecular weight PVC(DP 2500) was superior to that of DP 1300 for tensile strength, Hardness. But elongation and abrasion resistance of P1300 systems were better than those of P2500 systems. The densities of both systems were almost same. On the other hand, DOP Plasticized PVC was superior to DOA plasticized one for tensile strength, elongation, hardness. In cases of density, abrasion resistance, and flexual resistance, DOA systems were better than those of DOP systems.

The gasket materials of for the lithium ion battery requires chemical resistance to electrolyte, electrical insulating, compression set, anti-contamination and low temperature property. To check the special characteristics of fillers which are applied to rubber for gasket, compound of EPDM, NBR and FKM (fluoro elastomer) were made by adjusting weights of carbon black and silica additive. Using these compounds, we had done tests of long-term stability against electrolyte, compression set and low-temperature property with considering operating condition of the lithium ion battery. From this test, we investigated the physical and chemical characteristics of rubber with using of carbon black and silica additive in each.

Gigolphy(Lycii cortex Radicis) wine and its chemical components and physical properties were prepared and analyzed for development of Boxthorn product and utilization of Boxthorn. Chemical components and physical properties of this wine was analyzed. When this wine were evaluated by Amerine test and by concerning physico-chemical properties, the recipy including 20 % of sugar, and 2.0 % of Gigolphy powder were the most highly recommended for development of Gigolphy wine.

This study aims at generating a continuous map by coordinates transformation between cadastral maps with different surveying origins. The continuous cadastral map is useful in various fields of GIS. For this purpose, an experimental study was conducted at Osan-Si, Kyonggi Province in cooperation with related institutions. In this study, three control point zone, large, medium, and small zone were to!;ted. For each control point, the currently used data were compared with the data at the surveyed time. About coordinate transformation method, we tested Helmert, Affine, and Polynomial methods which are the most representative among 2-dimensional coordinate transformations. These three transformation methods were evaluated according to variation of transformed parcel shape and agreement with neighboring areas. As the result of the evaluation, Affine transformation in large zone is the most appropriate coordinate transformation method fer Osan-Si.

The purpose of this study was to survey junior high school teachers' and students' perceptions on the science textbooks. Subjects of this study were 113 science teachers and 715 students from junior high schools in Daegu and Kyungpook area. As statistical method, one-way ANOVA and t-test were used to check differences of the perceptions between teachers and students. Teachers had different perceptions by school location and class size, while students had different perceptions by school location, co-ed, class size, and grade level. Both teachers and students having the relativistic viewpoint on textbook knowledge regarded the knowledge as relativistic one, and preferred the student-centered textbooks. Teachers liked textbooks written by the student-centered view more than students did. Teachers had the more absolutistic viewpoint on textbook knowledge and on teaching, while students liked the electronic textbooks more than teachers did.

Experiments were conducted to know the inorganic compound absorption of leaf, and the organic component, oil content, fatty acid composition of seeds by different fertilizer levels and growth stage of Pungn-yeonggage. Ripening rate and seed yield were highest under the standard of nitrogen fertilizer level. Nitrogen and potassium amount of leaves were highest at 20 days after seedlings, but there was no difference in phosphate between growth stages. Absorptions of nitrogen and potassium were increased by applying double amount of nitrogen fertilizer. Oleic fatty acid content was found highest under the double amount of nitrogen, phosphate and potassium fertilizer level, and linoleic fatty acid content was increased with double amount of phosphate fertilizer level.

Teachers' teaching behavior is directly influenced by teachers' belief, and students' belief system is directly influenced by teachers' teaching behavior. There has been a question whether curriculum of teacher training university could help preservice teachers form positive belief system. The purpose of this study was to address this issue empirically. First, a questionnaire about mathematical belief was given to freshmen preservice teachers. They generally showed positive belief about mathematics to the degree that is not satisfactory and responded most positively in the sub-area of teaching mathematics from three sub-areas of mathematics itself, studying mathematics, and teaching mathematics. After studying a mathematical philosophy course, the freshmen preservice teachers were given the same questionnaire that they responded before studying the course. Belief about mathematics itself was changed very positively, and increase in the sub-area of mathematics itself was the largest. These results show that the mathematical philosophy course helped preservice teachers form positive belief system in mathematics.

Pholiota nameko is one of the four major profitable mushrooms along with oak mushroom, winter mushroom, and oyster mushroom. It contains abundant proteins, carbohydrates, organic acids and vitamins. Its unique taste and flavor as well as its nutritional features make it widely favoured. Mushroom complete medium was the optimal medium for mycelial growth of Pholiota nameko. The optimal temperature and pH for the mycelial growth were $25^{\circ}C$ and 5.0, respectively. The best carbon sources for mycelial growth were glucose and mannose, and the best nitrogen sources were yeast extract, peptone, asparagine, etc. The 8:2 ratio mix of oak sawdust and wheat bran was the best for the bottle cultivation. The best mushroom was yielded after 30 days incubation. The best yield was produced with 850g of medium weight in a PP bag and bottle.
