본 연구는 경희대학교 중앙도서관에서 도입한 통합형 전자도서관 시스템에 대한 이용만족도를 조사 및 분석한 연구결과이다. 도서관 웹사이트에 대해 시스템 변경전과 변경후로 설문을 실시하였으며, 웹사이트 만족도에 대한 주요 속성을 검색 및 결과표현, 접속방법, 디자인, 이용자서비스로 도출하였다. 그리고 각각 주요속성의 시스템적 변경에 따른 이용만족도의 변화에 대해서 분석한 결과 이용자서비스를 제외한 모든 주요 속성에서 긍정적인 만족도 변화를 확인하였다. 이에 본 연구에서는 신규 시스템 도입후 향후 수정 및 보완 방향에 대해 제시하고자 하였다. This study was undertaken to survey and analyze the user satisfaction of the integrateddigital library system that Central Library in Kyung Hee University had newly introduced. The survey itself was carried out respectively before and after the system alteration regarding library webpage. Main Categories such as Search, Search Results, Connection Process, Design, and User Service were listed in the survey form. And After tabulating and examining the survey, we conclude that there is a positive result on User Satisfaction Survey after the system alteration except User Service category. This study intends to focuson the future modification and direction of alternatives after the introduction of new system.

Circuit board assemblies experience various mechanical loadings during assembly and in actual use. The repeated cyclic bending can cause electrical failures due to circuit board cracks, solder interconnects cracks, and the component cracks. This paper presents a cylic bending tester developed especially for evaluating the reliability of board level flip chips under the repeated cyclic bending. The tester employs the concept of 4-point bending test and complies to JEDEC standard No. 22B113 that is intended to evaluate and compare the performance of surface mount electronic components in an accelerated test environment. The performance of the tester will be estimated through the cross check of the test results in the future work.

The Turkic languages and dialects are spoken by some 150 to 200 million people across a vast area from Pacific to the Baltic Sea, and from the Arctic Ocean to the Persian Gulf. They are Azerbaijani, Bashkir, Chuvash, Karaim,Karakalpak, Kazakh, Kyrgyz/Kirghiz, Modern Uyghur, Salar, Tatar, Turkish,Turkmen, Tuvan, Uzbek, Yakut, etc. The word referring to all these languages is Turkic, whereas the word Turkish is used for the Turkic language of Turkey. The Turkic languages are considered to be part of the proposed Altaic language family together with the Mongolic languages, the Manchu-Tungus languages, and/or the Korean language. If that is the case, it would be useful to use the Turkic material when studying the ancient history of the Koreans. However, the Turkic material is not well-known in Korea. Shamanism is a term for a range of beliefs and practices relating to communication with the spiritual world. The shamans are believed to be intermediaries or messengers between the human world and the spirit world. There is a view that Dangun(檀君), the legendary founding father of the first Korean state of Gojoseon(古朝鮮), was a shaman. It is obvious that shamanism is one of the main religious believes of the Korean people since ancient times. In the present paper we will treat the words related to shaman in the modern Turkic languages. We limit the words to ‘shaman’, ‘sorcerer, magician’,‘healer’, and ‘fortune-teller, soothsayer’. The words are obtained mainly from the various dictionaries of the modern Turkic languages.

In general, circuit board assemblies experience various mechanical loadings during assembly and in actual use. The repeated cyclic bending can cause electrical failures due to circuit board cracks, solder interconnects cracks, and the component cracks. In this paper, we report on the failure characteristics of semiconductor chips under the repeated cyclic bending. We first describe a new 4-point bending tester, which is developed according to JEDEC standard No. 22B113. The performance of the tester is then estimated through actual experiments. Test results reveal that the cracks first occur on the outer balls around 20,000 cycles and gradually propagate to the inner balls where cracks are found around 70,000 cycles.

The Huá-yí-yì-yǔ (華夷譯語) is a general name for the various wordbooks between the Chinese language and its neighboring languages compiled from the beginning of the Ming (明) dynasty (1368~1644). It has broadly 4 different classes. In the wordbooks of the third class the words of each foreign language were transliterated only in Chinese characters and the script of the language in question was not used. To this third class belongs the manuscript in the collection of the library of Seoul National University. Its seventh volume is concerned with the Uighur language. It contains 19 categories. Its fifteenth category is 方隅門 fāng-yú-mén ‘the category of direction’ with 15 entries, which will be treated in this paper.
