This study aimed to investigate the transition of academic libraries' jobs by developing a model based on a shift of library generations including Library 1.0, Library 2.0, and Library 3.0 corresponding to the shift of web generations and to explore generational characteristics of library duties as well. The research used three phases of procedure: literature review about different library generations; job analyses for academic libraries in South Korea and the U.S.A.; the Delphi technique in tree sequential order. The research findings were as follows. First of all, there were 170 duties that continued from Library 1.0 to Library 3.0. There were 58 duties which continued from Library 2.0 to Library 3.0 whereas three duties that continued from Library 1.0 to Library 2.0. In addition, three distinctive duties existed only in Library 1.0 whereas one unique duty was only in Library 2.0. Library 3.0 generated 25 new duties. Secondly, considering general characteristics which cover specific parts of individual duties, there was a significant increase in importance, difficulty, and frequency of library administration throughout the three generations. In terms of importance, difficulty, and frequency of collection development and management, there was a significant increase only from Library 2.0 to Library 3.0. Considering information organization, there was a significant decrease in importance from Library 1.0 to Library 2.0. In addition, there was a significant decrease in frequency and there was no significant difference in difficulty throughout the three generations. In the case of information service, while there was a significant increase in importance among three generations, there was a significant increase in difficulty only from Library 1.0 to Library 2.0. However, there was no generational difference in frequency. With the respect of information system development and management, there was a significant increase in importance and frequency throughout the three generations, but there was no significant difference in difficulty among three generations.

고대 천문기록을 연구하는 과정에서 기록의 사실 여부와 함께 천문기록에 영향을 미치는 요소를 확인하는 것은 중요하다. 본 연구에서는 고대의 천문기록 중에서 관측 빈도수가 높은 유성과 유성우 기록을 통해 이들의 분포와 역사적 환경 요소와의 관련성을 알아보았다. 유성과 유성우 기록을 분석한 선행연구에 의하면 한국과 중국 일본의 고대 유성과 유성우 기록은 잘 알려진 주기 유성우의 특성을 잘 보여준다. 그러나 인접한 세 나라의 관측 기록은 시대별로 일부 다른 분포를 보이는데 이러한 이유를 알아보기 위해 세 나라의 역사적 환경과 천문기록 분포와의 상관관계를 조사하였다. 본 연구에서는 1200년부터 1700년까지 500년 동안의 왕조-왕위교체, 외부침략, 내란과 같은 역사 사건을 조사하여 중요도에 따라 세 등급으로 나누고 이들을 유성과 유성우 기록 분포와 비교하였다. 연구 결과, 한국과 중국 일본의 고대 유성과 유성우의 기록 분포와 역사적 사건과는 서로 관련성이 없는 것으로 나타났다. 이것은 세 나라의 고대 천문관측 기록이 정치적 사건의 영향을 받지 않았음을 의미한다. 고대 천문기록을 분석할 경우 역사적 사건이나 왕위교체 등의 사회적 영향보다는 시대별 천문기록의 분포개수를 고려한 가중치가 중요하게 고려되어야 할 것이다.

This paper confirms characteristics of lead isotopes of bronze artifacts excavated from Korea peninsula using 673 data classified according to Age, type and region. Lead isotopes data in Early iron ages are distributed in the southern Korean peninsula, but data in Joseon ages are concentrated in zone 3. Also Bronze artifacts excavated from Seoul, Gyeonggi, Chungcheong, Jeolla and Gyeonsang are manufactured using raw materials of the entire Korea peninsula, but bronzes excavated from North Korea aren't produced using raw materials of Gyeonsang provinces. Lead isotopes data will be able to find moving routes of raw materials and to separate the period of mixing and recycling of lead.

This study was examined interpretation of making techniques and provenance interpretation of raw materials for the potteries from the Nongseori site in Giheung based on archaeometric characteristics. The potteries are classified into three groups according to the archaeological age. The texture of Neolithic age potteries is sandy soil added a lot of temper such as talc and mica, and Bronze age potteries contain sandy materials which occur naturally include quartz, orthoclase, plagioclase and mica. On the other hand, Proto-three Kingdom Age potteries made of silty soil that sift out coarse minerals from the clay. But all pottery and soil samples in the study were very similar patterns with geochemical evolution trend. This result is sufficient evidence that all pottery samples were produced using the same raw materials from the host rocks around of the site area. The Neolithic age potteries had loose texture and fired probably about 700 to $760^{\circ}C$. The Bronze age potteries had experienced firing about 850 to $900^{\circ}C$. And Proto-three Kingdom Age potteries had compact textured and fired from 900 to $1,050^{\circ}C$. The making techniques of potteries are not represented discontinuation characteristics about the periodic time sequences, and are suggested that revealed a transitional change patterns for production techniques.
