The present study examines the characteristics of the international literature of classification systems published in the period 1981-1990. The references in the "Classification Literature" sections of International Classification and the references in these source items were examined. The present study focused on analyzing each of the following characteristics: format, subject, language, geographical origin, age, authorship and number of references. The findings form the data analyses show clearly that in the literature of classification systems, 1) books were the most frequently cited format; 2) library and information science was the most frequently cited subject; 3) English was the major language; 4)the literature of each classification system was written predominently in English except for Library Bibliographic Classification; 5) the language of each source item was the same as that of the greatest number of references of that source item; 6) the U.S, Germany, India, Russia, and the U.K. were the major geographic origin of publication; 7) there was a very close relationship between country of publication and language; 8) the country of origin of the documents was cited more than any other country except for the U.S.; 9) Price's Index of the literature was about 7.5 years; 10) there was a preponderance of single authorships; 11) the literature was not a scholarly or scientific literature, according to the average number of references in source items and the percentage of unreferenced items. The findings of this reference study provide a better understanding of the characteristics of the classification systems literature. They prove useful for the collection development and assist classification systems researchers to prepare linguistically for their careers and encourage international communication efforts

Gypsum products have potential contamination by infectious human pathogens, which could be transmitted from patient to the gypsum model via impression materials. Therefore disinfection and sterilization of gypsum products are recommended. Steam sterilization: namely autoclaving is widely available in dentistry. The aim of this study was to investigate degradation of mechanical properties for dental gypsum after steam sterilization. The effect of autoclaving on compressive strength, weight loss and dimensional accuracy of specimens of commercial die stone such as Crystal Rock(CR : Maruishi), Die Keen(DK : Columbus Dental), Resin Rock(RR : Whip Mix), Tuff Rock(TR : Talladium) were estimated, and experimental gypsums{(EP) : 0.5wt% accelerator, 0.02wt% retarder, 0.1wt% surface agent, 0.1wt% Poly Vinyl Acetate} were also measured the above properties after autoclaving. For each group, five cylindrical(6㎜ in diameter and 12㎜ long) specimens made with manufactures water:powder ratio. All specimens were dried in oven until reaching the constant mass. After dried, they were autoclaved at 121℃ for 20 minute, dried again. Compressive strength was measured before and after autoclaving using mechanical testing machine at a cross-head speed of 0.5㎜/min. The dimensional accuracy was estimated by length change of specimens with digital caliper before and after autoclaving. For statistical analysis, ANOVA Tukeys Studentized Range(HSD) test and T test were used. Compressive strength and weight were decreased in all samples after autoclaving. There is significant difference between CR, DK and RR, TR in after autoclaving(p<0.05). EP exhibited the highest compressive strength after autoclaving. The weight was significantly decreased in all group except RR after autoclaving(p<0.05). The dimensional accuracy was not significantly increased in all group except CR. As this result, we found that resin-containing dental stone is more appropriate for autoclaving in dentistry.

Renal ischemia is one of the most common causes of acute renal failure. Four factors related to the pathogenesis of acute renal failure are vasoconstriction, decreased glomerular filtration rate, tubular back leak of filtrate, and intratubular obstruction. The cellular response to renal ischemic insults include decreased content of adenosine trihosphate, lipid peroxidation induced membrane degradation, alteration in cellular pH, and calcium or phospholipase induced mitochondrial dysfunction. Much attention has been given to the role of increased cellular calcium as a pathogenetic contributor to cell injury during ischemia. Author studied the protective effects of calcium antagonists on cellular injury during renal ischemia in rat. To investigate the protective role of these agents, author measured the amount of malondialdehyde(MDA) and the enzyme activities of free radical scarvengers-superoxide dismutase(SOD), catalase and glutathione peroxidase from non-pretreated group and calcium antagonists pretreated groups in control, ischemia and reflow subgroups. The results were summerized as follows: 1) The amount of MDA in non-pretreated group was higher in the reflow compared with the control(<p<0.01). But, in all pretreated groups, there was no statistically difference in the amount of MDA. 2) The SOD activity in non-pretreated group was lower in both the ischemia and the reflow compared with the control (P<0.05). But, in both verapamil and trifluoperazine-pretreated groups, there was no statistically difference in the SOD activity. 3) Both catalase and glutathione peroxidase activities in non-pretreated group were lower in both the ischemia and the reflow compared with the control (P<0.05). But in all pretreated groups, there was no statically difference in both catalase and glutathione peroxidase activities. These results suggest that free radical mediated ischemic injury by renal artery clamp in rat can be protected by intraperitoneal pretreatment with calcium antagonists. As trifluoperazine has a protective effect in renal ischemia, the calcium activated calmodulin dependent enzyme may play a role in renal ischemic injury.

동일한 시료에 대한 국내 기관간의 STR 분석결과 비교 : STR 유전자좌 분석법의 표준화 설정을 위하여

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. One routine chest film of a patient who was checked and hepatoma-diagnosed in Internal Medicine, Chosun University Hospital left the room for doubt of mediastinal mass. But no subjective symptoms for the mass was told by the patient. This is to report our experience of a patient having right side aortic arch with aberrant left subclavian artery, as proved by diagnosis, but none of congenital heart disease. This right side aortic arch with aberrant left subclavian artery is the most frequent type among right aortic arch, the anomaly of which is usually detected from the incidental suspicion for mediastinal mass at routine chest film; because no symptoms are accompanied therewith.

한국 현대 태피스트리 작가 연구 - 송번수(宋繁樹) -

정경연(Chung Kyoung Yeon),피경지(Pi Kyeong Ji) 한국조형디자인학회 2016 조형디자인연구 Vol.19 No.3

한국 근현대 공예는 실용성보다 작가 고유의 창작성을 표현하려는 순수미술로의 성격이 두드러 진다. 태피스트리는 서양에서 발달한 직물 중 하나로 한국에서는 20세기 중반부터 섬유미술 작가들에게 작품세계를 표현하는 새로운 기법으로 받아 들여졌다. 1980~90년도에 수직(手織)기법을 활용하는 작가들이 증가하였고 따라서 다양한 작품들이 발표되면서 한국 현대 섬유미술의 주요한 영역으로 자리 매김하게 되었다. 이와 같은 현상은 섬유미술사적으로 매우 중요한 사적 전환점으로서 진지한 연구의 필요성이 요구되었으며, 태피스트리 작가 연구를 통하여 수직기법이 가진 조형성과 가치를 분석하여 섬유 미술 분야의 학문적 기초 자료로 남기고자 하였다. 송번수의 예술세계를 조망함에 있어서 판화와 태피스트리, 환경조형물은 별개로 유리된 것이 아니라 매체적 실험과 조형적 표현욕구 속에 상호보완적인 관계망으로 연결되어 있다는 인식은 대단히 의미 있는 해석이 아닐 수 없다. 1960년대 이후 판화의 조형적 변주들은 고스란히 이식되어 태피스트리로 옮겨지거나 판화 혹은 태피스트리 작업 자체에서 드러나는 장르 특징적 성격을 지니면서 뚜렷하게 부각되었다. 따라서 송번수의 예술세계에서 판화와 섬유미술이라는 모더니즘의 형식적 장르구분은 의미를 상실한다. 그에게 중요한 것은 매체나 기법의 문제가 아니라 ‘무엇을 표현할것인가’에 관한 끊임없는 예술적 질문과 실험이기 때문이다. 필자는 이러한 그의 생애와 작품세계고찰을 통해 시대적 배경을 기록하고 수직 작품의 특징적인 조형성을 분석하여 한국 현대 섬유미술의 단면을 기록하고자 한다. 연구범위는 태피스트리 작품으로 한정하고 작가와의 인터뷰를 중심으로 하였으며 그와 관련한 태피스트리 문헌연구로서 논을 완성 하였다. Modern and contemporary Korean crafts have the distinctive characteristics of pure art, which express the artists’ unique creativity, rather than practicality. Tapestry is a textile-based form of artwork that has been developed in the West, and it was transmitted to Korea around the mid-20th century as a new technique by which textile artists could express their artistic ideas. During the 1980s~90s, many artists started to use a hand-weaving technique and presented various artworks accordingly, developing into a major area of Korean modern faber art. Such phenomena have marked an important historical turning point in the history of Korean faber art and serious research on this field is needed. In this paper the formativeness and value of hand-weaving techniques will be analyzed through research on tapestry artists, and the results of such research will serve as the basic data in the field of faber art. In the artworks of artist Song, Burn-soo, printmaking, tapestry and environmental sculptures are not separated from each other. It is important to interpret them within an inter-complementary network as the artist’s desire to experiment with media and express his ideas through sculpture. In the 1960s, the formative variation of printmaking began moving wholly to tapestry, or took up a form of genre as revealing the work of printmaking or tapestry. Accordingly, in the art world of artist Song, Burn-soo, the formal classification of genre of modernism such as printmaking or fabric art loses its meaning. This is because what is important to him is not a matter of media or technique, but of ceaseless artistic questioning and experimenting with regard to “What to express.” This writer attempts to record this aspect of Korean modern faber art by analyzing the formative characteristics of hand-woven artwork and to record the historic background by examining Song’s life and art. The scope of this research focuses on the tapestry work through interviews with the artist and through a literature review of his tapestry work.

학문분류, 문헌분류, 연구분류에 관한 비교 분석

정연경(Yeon Kyoung Chung) 이화여자대학교 이화사회과학원 1999 사회과학연구논총 Vol.3 No.-

현대의 학문 체계는 어떻게 수립되어야 하고, 그 체계 속에서 각각의 학문은 어디에 있어야 하며, 거기에서 학문이 담당해야 할 역할이 무엇인가? 학문 영역의 전반적인 검토를 바탕으로 우리 현실에 맞는 학문체계가 수립되어야 할 필요성이 있다. 새 천년의 시대를 맞이하고 있는 시대야말로 여러 학문의 흐름을 살펴보면서 세계를 하나의 시각으로써만이 아닌 다양한 시각으로 봐야할 필요성이 있다. 이제 우리는 여러 학문 영역에서의 급속한 변화와 발전의 추세를 쫓아가며 단순히 모방하는 것을 넘어, 세계 속의 우리 학문을 발전시키고 우리 스스로 의미 있다고 생각하는 연구에 전념하기 위해서는 보다 기본적인 성격의 작업이 필요하다. 즉 스스로 하고 있는 연구 주제의 성격과 의미에 대한 정리가 필요하다. 본 연구는 그 첫 번째 작업으로 학문이 어떻게 분류되어 왔으며 그 결과물인 문헌이 어떻게 분류되어왔고 그 문헌을 바탕으로 이루어지는 연구가 어떻게 구분되어 발전되어 왔는지를 학문분류, 문헌분류, 연구분류 고찰을 통해 비교 분석하였다. 분류가 과학적이고 교육적인 지식 체계에 따를 때 그 효용성이 증가된다고 하였으며 그 원리는 지식의 본질에 대한 충분한 이해에 기초를 두어야 한다고 했다. 그러므로 학문적 이론을 충족시키는 문헌분류표와 연구분류표 개발을 바탕으로 효율적인 정보조직을 이루어야 할 것이다. 그러기 위해서는 분류체계의 많은 항목들이 학문의 기술적, 학술적 분류와 일치하도록 만들어져야 할 것이고 문헌분류와 연구분류가 학문분류에 적합하도록 재구성할 필요가 있다. 그리고 전통적인 사고에 구애받지 않고 새로운 학문분류를 시도하려는 학자들과 문헌이나 연구의 효율성을 높이려는 분류학자들 사이에 충분한 의사 교환이 이루어져, 보다 실용적인 현대 학문의 세분화와 그 발전을 수용할 수 있는 분류에 관한 연구가 필요하다. How the modem knowledge classification should be established and where the disciplines should be and what is the role of the discipline? Upon the basis of the review of overall areas of the disciplines, there is a need to establish the knowledge classification that is proper for our situation. Towards the new millennium, it is necessary to view the world through the various eyes with the stream of many disciplines. Now, we need a more basic work in order to concentrate on a meaningful research by ourselves and to develop our disciplines in the world. That is the summary of the characteristics and the meanings of the research areas by ourselves. This study is the first work to compare and analyze the knowledge classification, the library classification, and the research classification. The effectiveness of the classification is increased when the classification is made by the structure of scientific and educational knowledge. Therefore the theory of the classification should be based upon the true understanding of the nature of the knowledge. And the effective organization of information should be based upon the development of the library classification and research classification that is matched for the knowledge classification. In order to do it, we need to reorganize the library classification and research classification according to the broad structure of knowledge classification. And we need more studies on the practical classifications that are hospitable to the development and specialization of the modern knowledge through the communication among the scholars and classifiers who have a new idea of the knowledge classification and the effectiveness of the use of library and research classification.

대학도서관 데이터 분석을 통한 대학생 독서 지원 서비스 방안 연구

정연경 ( Chung Yeon Kyoung ) 한국독서학회 2017 독서연구 Vol.0 No.43

청년 실업이 사회적 문제로 대두되면서 대학 졸업 후, 취업 여부가 대학의 역할을 재조명하고 있다. 이러한 대학 환경의 급격한 변화는 대학생들의 독서에 영향을 미칠 수밖에 없고 이에 관한 많은 연구가 필요하다. 그러나 대학생 독자의 특성과 요구에 관한 연구는 다른 독자층에 비해 매우 적게 이루어졌다. 본 연구는 선행연구와 함께 대학도서관의 다양한 통계치와 대학도서관의 다년간 대출 데이터 분석을 통해 대학생 독자들의 특성을 살펴보고 이를 바탕으로 대학생 독자를 위한 대학도서관의 새로운 독서 지원 서비스인 독서 프로파일링 서비스를 제안하였다. As unemployment of university graduates has emerged as a social problem, the role of the university has been reaffirmed. The dramatic changes in the environment of the universities are bound to affect the reading rates of the university students and more studies regarding these subjects are needed. However, less research on the characteristics and reading needs of the university students was carried in comparison of the studies of other levels of students. This study examines the characteristics of university students by analyzing various statistical data of university libraries and 5 years library circulation data and suggests a new reading profiling service which is a proactive reading support service for university students as a personalized book curation.
