본 논문에서는 용액 공정을 이용한 고분자 절연층을 갖는 top-gate 구조의 펜타센 박막 트랜지스터(Thin Film Transistor, TFT)의 특성을 연구하였다. Top-gate 구조의 펜타센 TFT 제작에 앞서 유기 반도체인 펜타센의 결정성 성장을 돕기 위해서 가교된 PVP (cross-linked poly(4-vinylphenol))를 유리 기판 상에 스핀 코팅을 이용하여 형성한 후, 노광 공정을 통해 니켈/은 구조를 갖는 채널 길이 $10{\mu}m$의 소오스, 드레인 전극을 형성하였다. 그리고 열 증착을 이용하여 60 nm 두께의 펜타센 층을 성막하였고, 고분자 절연체로서 PVA(polyvinyl alchol) 또는 가교된 PVA를 용액공정인 스핀 코팅을 이용하여 형성한 후 열 증착으로 알루미늄 게이트 전극을 성막하였다. 이로써 제작된 소자들의 전기적 특성을 확인한 결과 가교된 PVA를 사용한 펜타센 TFT 보다 PVA를 게이트 절연체로 사용한 소자가 전기적 특성이 우수한 것으로 관찰되었다. 이는 PVA의 가교 공정에 의한 펜타센 박막의 성능 퇴화에 기인한 것으로 사료된다. 실험 결과 $0.9{\mu}m$ 두께의 PVA 게이트 절연막을 사용한 top-gate 구조의 펜타센 TFT의 전계 효과 이동도와 문턱전압, 그리고 전류 점멸비는 각각, 약 $3.9{\times}10^{-3}\;cm^2/Vs$, -11.5 V, $3{\times}10^5$으로써 본 연구에서 제안된 소자가 용액 공정형 top-gate 유기 TFT 소자로서 우수한 성능을 나타냄을 알 수 있었다.

For the sake of the Restoration(to the original state) of "Sanbeon-bang(刪繁方)", in this study observed carefully the bibliographical results of "Oedaebiyo-bang", "Cheongeumyo-bang", "Cheongeumik-bang" and "Uisim-bang", which directly quoted "Sanbeon-bang". "Sanbeon-bang" is mostly remained in "Oedaebiyo-bang", and the other provisions of "Sanbeon-bang" mostly lie scattered in "Cheongeumyo-bang" and "Cheongeumik-bang", established 100years before "Oedaebiyo-bang" and "Uisim-bang", established 200years after "Oedaebiyo-bang". And there are few other documents which quoted the "Sanbeon-bang". "Cheongeumyo-bang", a synthetic medical work was compiled in 652, and which refered large quantity of medical documents before Dang-dynasty(唐代) by Son Sa-mak(孫思邈). And he linked the technical opinion of himself. The comments of medicine, as well as the prescriptions are refleting the outcome before Dang-dynasty systematically. For the most part of the medical arguments in "Sanbeon-bang" lie scattered in "Cheongeumyo-bang". "Cheongeumik-bang", also a synthetic medical work which is for the sake of supplement of "Cheongeumyo-bang" was complied in 682 by Son Sa-mak. As well as "CheongeumYo-bang" it doesn't make clear the sources of quotation from "Sanbeon-bang". So it used as the data for confirmation. "Oedaebiyo-bang" was compiled in 752 of Dang-Dynasty by Wang Do(王燾) the a governor-general of Eop-gun. Wang Do was descended from a noble family, and usually visited the palace and dealed with large number of books in Hongmunguan(弘文館), the national library. He programmed the book on the base of wide scopic collection of medical documents. And he took charge of gverment post at the same time as Wang Bing(王氷) who compiled "Chaju-Hwangje-Naegyeong-Somun(次注黃帝內經素問)" in 762. So we can guess they might have seen the same documents and holded the medical knowledge in common. The 40 volume "Oedaebiyo-bang" was a great medical complete book in those days. In particular, it became the model of medical complete books of after ages. The description of the book is mostly the qutation of medical documents of before ages. The character is recording of quotation documents and the order of volume. On the base of the recording, we can reconstruct the table of contents of Sanbeon-bang. By way of the contens, we can understand the purpose of "Sanbeon-bang". Besides, I can see a lot of qouotations of "Sanbeon-bang" in "Cheongeum-bang" and "Uisim-bang" are repeatedly quotated in "Oedaebiyo-bang". For that reason, I observed the bibliographical results of "Oedaebiyo-bang" in detail. "Uisim-bang" was compiled in 982 by the Japanese Niwayasyori(丹波綱賴). It followed the example of the structure of "Oedaebiyo-bang", refered to the contents of "Cheongeumyo-bang", collected chinese medical classic books spreaded in Japan. It contains medical documents of before Su-Dang(隋唐)-era, indicated the source of quotation. The importance of the book is summarization and preservation of large quantity of chinese medicine before 10th century. In this study, a lot of the quotation in "Uisim-bang" from "Sanbeon-bang" were not in "Oedaebiyo-bang".

A new blue phosphorescent material for organic light emitting diodes (OLEDs), Iridium(III)bis[2-(4-fIuoro-3-benzonitrile)-pyridinato-N,C2'] picolinate (Firpic-CN), was synthesized and studied. We compared characteristics of Firpic-CN and Bis(3,5-Difluoro-2-(2-pyridyl)phenyl-(2-carboxypyridyl) iridium III (FIrpic) which has been used for blue dopant materials frequently. The devices structure were indium tin oxide (ITO) (1000 ${\AA}$)/N,N'-diphenyl-N,N'-(2-napthyl)-(1,1'-phenyl)-4,4'-diamine (NPB) (500 ${\AA}$)/4,4'-N,N'-dicarbazole-biphyenyl (CBP) : FIrpic and FIrpic-CN (X wt%)/4,7-diphenyl-1,10-phenanthroline (BPhen) (300 ${\AA}$)/lithum quinolate (Liq) (20 ${\AA}$)/Al (1000 ${\AA}$). 15 wt% FIrpic-CN doped device exhibits a luminance of $1450\;cd/m^2$ at 12.4 V, luminous efficiency of 1.31 cd/A at $3.58mA/cm^2$, and Commission Internationale d'Eclairage $(CIE_{x,y})$ coordinates of (0.15, 0.12) at 12 V which shows a very deep blue emission. We also measured lifetime of devices and was presented definite difference between devices of FIrpic and FIrpic-CN. Device with FIrpic-CN as a dopant presented lower longevity due to chemical effect of CN ligand.

This study analyzes periodic phenomena on publication and characteristics of Buddhist scriptures engraved on woodblock in temples located in Hwanghae Province during the Joseon Dynasty period in bibliographic approach. There are total 85 Buddhist scriptures published in Hwanghae Province, 5 scriptures among them including Yonggamsugyeong appear to be engraved on woodblock only in temples in Hwanghae Province. They, published in 64 printings during the early days of the Joseon Dynasty, occupy 75% of total Buddhist scriptures, and are analyzed to be intensively published with the support of royal family members such as Queen Munjeong in the reign of King Myeongjong. However, as the publication displayed a sharply declining tendency in the late Joseon period after the Japanese invasion, it is understood to be identical with historical fact that the people's livelihood in Hwanghae Province closed to ruin through invasions from Japan and Manchuria. In addition, the analysis on characteristics of these Buddhist scriptures by subject indicates that over 80% of them are generally sacred books and dogmas. In fact, woodblock engraving works in temples emphasize on the duty of an engraver, and many engravers are investigated that they engraved only 2 to 3 Buddhist scriptures in temples located in Hwanghae Province. Doseong and Suyeon can be regarded as remarkable itinerant monks as they were appeared to engrave Buddhist scriptures in not only Hwanghae Province and also other regions by moving from one place to another. This study is expected to be meaningful as a paper that can be used on future studies to compare Buddhist scriptures engraved on woodblock in other regions in North Korea.

The purpose of this study is to examine and propose to improve the features of a simple keyword search box and faceted navigations of KOLIS-NET operated by the National Library of Korea. A record group of '2011-2020 (776)' under 'Publication date' facet, out of 3,702 records retrieved from a search of '김훈', were examined. Major findings are as follows: (1) Five facets including 'Format', 'Publication date', 'Subject', 'Language' and 'Country' are used to limit search results only in the first step, and multiple facets cannot be simultaneously used; (2) With 'Publication date' facet formed in the span of ten years, a separate publication year cannot be identified; (3) 'Subject' facet based on KDC limits the results only in broad subject classes without sub-facets; (4) Under 'Format' facet, a special format such as large print texts cannot be identified; (5) Without 'Author' facet, authors cannot be identified; and (6) 'Publication date missing', 'Language missing', and 'Miscellaneous subject' record groups cannot be clicked and displayed, a navigation to-and-fro between a brief list and bibliographic records is not smooth, etc. Therefore an application of multiple facets in all stages of limiting the search result, a construction of sub-facets for 'Publication date' and 'Subject' facets, an accurate description and coding of 'General Material Designation', etc. are suggested to improve KOLIS-NET's faceted navigation.

This study analyses the questions and answers contained in the Knowledge Information Database of the collaborative digital reference service, 'Ask a librarian'. And based on the results of status of user requests, this study draws information usage behavior in the early stages of the service was derived. 1,124 Knowledge Information Database items out of 3,506 cases was analyzed by nine criterion. ① Number of questions and whether to be reference questions, ② Subject and keywords of the question, ③ Purpose of the question, ④ Type of question, ⑤ User's information request, ⑥ Information source and reference services provided by the librarian, ⑦ Number of days to answer, ⑧ Level of the participating library, ⑨ Question type by topic. As a results of analysis, first, users asked for reference questions from various topics as needed, rather than one from a similar topic at a time, but more than half of the total pure reference questions were from the field of library information science. Second, about 71.35% of users were using the 'Ask a librarian' service to recommend a list of information resources related to a particular topic or research problem, and there were also questions that required consultation on the reading situation. Third, the most preferred sources of information for users were bibliography, and in the case of online information sources, users did not relatively prefer them. Fourth, the number of days required to answer was able to confirm significant differences depending on the type of question and the level of the participating library. Fifth, 31.33% of the purpose of the general field question showed that were self-generated.

The purpose of this study is to design textbook metadata as a basic task for building a textbook database. To this end, reading textbooks were defined as a category of textbooks, and a metadata development methodology was established through previous research. In order to ensure that bibliographically essential elements are not omitted, the catalog description elements of institutions that collect, accumulate, and service textbooks such as the National Library of Korea were investigated. The elements of Dublin Core, MODS, and KEM were mapped to derive elements suitable for describing textbooks. Finally, a set of textbook metadata elements consisting of 14 elements in three categories - bibliography, context, and textbook characteristics were presented by adding publication type, genre, and curriculum period elements. The 14 elements are titles, authors, publications, formats, identification sign, languages, locations, subject names, annotation, genres, table of contents, subjects, curriculum period, and curriculum information. In this study, we contributed to this field by discussing how to organize textbook resources with national knowledge resources, and in future studies, we proposed to evaluate usability by applying metadata elements to actual textbooks and revise and supplement them according to the evaluation results.

Since information scientists have begun trying to quantify significant research trends in scientific publications, '-metrics' research such as 'bibliometrics', 'scientometrics', 'informetrics', 'webometrics', and 'citation analysis' have been identified as crucial areas of information science. To illustrate the dynamic research activities in these areas, this study investigated the major contributors of '-metrics' research for the last decade at three levels: nations, institutions, and documents. '-metrics' literature of this study was obtained from the Science Citation Index for the years 2001-2011. In this analysis, we used Pathfinder network, PNNC algorithm, PageRank and several indicators based on h-index. In terms of international collaborations, USA and England were identified as major countries. At the institutional level, Katholieke University, Leuven and the University of Amsterdam in Europe and Indiana University and the Office of Naval Research in the USA have led co-research projects in informetrics areas. At the document level, Hirsch's h-index paper and Ingwersen's web impact factor paper were identified as the most influential work by two methods: PageRank and single paper h-index.

Since 1966 when the Journal of the Korean Society of Oceanography was founded, more than 1,200 scientific papers have been published. Among them, papers for the biological oceanography constitute the largest portion of 37%, followed by the physical oceanography with 25%, and then the geological oceanography with about 17%. Papers on the chemical oceanography (CO) accounts for about 20% with around 250 papers. The field of the chemical oceanography generally occupied more than 20% since the first issue, but it declined down to 10% from the 1980s to the 1990s, and has regained to more than 20% since the late 1990s. Most of the CO research sites were at Korean coastal area, and 1/3 of the papers were on the South Sea, 1/4 on the Yellow Sea and another 1/4 on the East Sea. Nearly 60% of the CO papers were on seawater studies and about 30% on sediment studies. The main topic of the CO research was nutrients, followed by metals, isotopes, environmental pollution, organic pollution, organic matter, and gases. Most of the first authors belonged to the university, but the Korea Institute of Ocean Science and Technology (including the whole body) was the affiliation with the single largest group of the first authors.
