$\underline{Purpose}$: To analyze the recent citation trend and to find a way to improve impact factor (IF) of the Journal of Korean Therapeutic Radiology and Oncology (JKSTRO) by analysis of Korean Medical Citation Index (KoMCI) citation data of JKSTRO and comparison with that of mean citation data of all journals enlisted on KoMCI (KoMCI journals) during 2000-2005. $\underline{Materials\;and\;Methods}$: All citation data of entire journals enlisted on KoMCI and JKSTRO from 2000 to 2005 were obtained from KoMCI. The trend of total and annual number of published articles and reference citations, total citations and self-citations per paper, IF and impact factor excluding self-citations (ZIF) were described and compared on both KoMCI journals and JKSTRO. $\underline{Results}$: Annual number of published articles was decreased for 6 years on both KoMCI journals and JKSTRO (32% and 38% reduction rate). The number of Korean journal references per article is 1.6 papers on JKSTRO comparing to 2.0 papers on KoMCI journals. The percentage of Korean references/total references increased from 5.0% in 2000 to 7.7% in 2005 on JKSTRO and from 8.5% in 2000 to 10.1% on KoMCI journals. The number of total citations received/paper on JKSTRO (average 1.333) is smaller than that of KoMCI journals (average 1.694), there was an increased rate of 67% in 2005 comparing to 2000. The percentage of self-citations/total citations (average 72%) on JKSTRO is slightly higher than that of KoMCI journals (average 61%). IF of JKSTRO was gradually improved and 0.144, 0.125, 0.088, 0.107, 0.187, and 0.203 in 2000-2005 respectively. However, ZIF of JKSTRO is steadily decreased from 0.038 in 2000 to 0.013 in 2005 except 0.044 in 2004. $\underline{Conclusion}$: IF of JKSTRO was slightly improved but had some innate problem of smaller number of citations received. To make JKSTRO as a highly cited journal, the awareness of academic status of JKSTRO and active participation of every member of JKSTRO including encouraging self-citations of papers published recent 2 years and submission of English written papers, and active academic cooperation with related academic societies.

본 연구는 충주댐 유역을 대상으로 미래의 기후변화, 그에 따른 식생상태, 그리고 미래의 토지이용 변화를 고려한 상태에서 SWAT-K 모형에 의한 수문순환인자들의 변화가 댐의 유입량에 미치는 영향을 파악하고자 한다. SWAT 모형의 검보정은 6년간($2000{\sim}2006$, 2001년 제외)의 댐유입량 자료를 이용하여 실시하였으며, Nash_Sutcliffe 모형효율은 $0.52{\sim}0.88$의 범위로 검보정되었다. 기후변화 시나리오는 IPCC에서 제공하고 있는 GCM들 중에서 CCCma CGCM2의 A2, B2 시나리오를 이용하였으며, 댐유역의 기후변화를 모의하기 위하여 과거 30년간($1977{\sim}2006$)의 기상자료 통계정보를 기준으로 Change Factor Downscaling 기법을 적용하여 2030년, 2060년, 2090년 전후의 각 30년간의 미래 정보를 재생산하였다. 미래의 식생정보는 7년($2000{\sim}2006$)간의 MODIS 위성 영상에 의한 엽면적 지수를 월단위로 구축하여 엽면적 지수와 평균기온간의 상관회귀식을 도출하여 미래 기후변화에 따른 식생의 활력도를 예측하였다. 미래의 토지이용 변화는 CA-MArkov 기법을 개선, 적용하여 총 9개의 토지이용 항목에 대하여 각 항목별 예측을 실시하였다. 2000년의 기상자료 및 댐유입량을 기준으로 이상의 미래기후, 식생, 토지이용 에측 정보를 적용하여 미래의 댐유입량을 모의한 결과를 분석하였다. 그 결과 강수량 및 온도의 변동이 가장 크게 영향을 주어 유입량의 변화가 모의되었으며, 이에 따른 수문인자의 변동은 2000년 기준으로 증발산량, 토양수분의 변동을 분석하였다. 미래의 수문순환에 가장 큰 영향을 주는 수문인자는 토양수분으로 나타나, 미래에는 산림지역 및 토지이용 개발에 따른 토양수분의 함양량 유지를 위한 유역관리가 중요한 요인이 될 것으로 나타났다.

This study investigated the image of library in our society by analyzing newspaper articles related to libraries. A total of 3065 newspaper articles reported in Kyunghyang, Hankyoreh, Chosun, and Joongang from 2000 to 2017 were analyzed using time series analysis. The results of the time series analysis showed the number of newspaper articles related to library declined to a peak in 2009. Also, there were differences in the content of newspaper articles by year except for those content related to books. There were many articles about 'information' and 'use' in early 2000, about 'library operation and opening', 'culture' from 2006, and about 'residents of the area', 'culture' after 2012. These content of newspaper articles may reflects the image of library in our society. Finally, this study dis cussed practical ways of public library promotion.

We investigated the effects of death and gametogenesis by infection of the trematode in the venus clam, Cyclina sinensis. The specimens of C. sinensis were collected monthly at the tidal flat of Kaehwado, Puan-gun and Sangpo aquafarms, Kochang-gun, Chollabuk-do, Korea, from June 1999 to May 2000. One species of a trematode, the metacercaria of Himasthla kusasigi Yamaguti, 1939 (Enchinistomatidae), was found in the venus clam, C. sinensis. Infection rates in Kaehwado area and Sangpo aquafarm were average 93% and 81%, respectively. Infection rates during the study period reached the maximum (100%) in September 1999 and March-April 2000 and showed the minimum (80%) in July in Kaehwado, while those in Sangpo aquafarm showed the maximum (99%) in January 2000 and the minimum (47%) in November 1999. The infection parts of the metacercaria of H. kusasigi in the venus clam were the visceral mass, gill, mantle including the foot. Their infection rates in Kaehwado area and Sangpo aquafarm were 76.7% and 81.3% in the visceral mass, 19.1% and 14.5% in the gill, and 5,1% and 4.2% in the mantle, respectively. Infection rates of H. kusasigi showed higher with the increase of the size of the clams. No abnormal characteristics in the various tissues by histological observations were found in the clams infected by the metacercaria of H. kusasigi because this clam is the second intermediate host.

Different from the existing tendency to mainly concentrate on the study of research activities of the library and information science, this paper places the focus on grasping research patterns presented in the journal papers which reflect library Practices. Actually, this paper analyzes research areas, the degree of relative dependence by subjects, and leading journals found in the papers which have been reported in the three main library journals such as "Tosogwan", "National Assembly Library Review", and "KLA Bulletin : Tosogwanmunwha" from 1996 to 2000. As a result, the study says that major research areas in library practices show the high degree of dependence on the library and information science, while the degree of dependence on the information science is low.he information science is low.

In this study, we aimed to identify the impact of socioeconomic characteristics on the health status of Chinese, which suggests that there might be the phenomena of health inequality in China. We used the year 2000, 2004 and 2009 pooled cross-sectional data of China Health and Nutrition Survey (CHNS), and utilized the Ordinary Least Square model (OLS) and Ordered Logit Estimation Method for this purpose. Empirical results showed that socioeconomic status and year dummy variables have a meaningful impact on Chinese health status. Therefore, we conclude that the phenomenon of health inequality has existed in China since 2000.

1999년 한 해 국내 미니랩 장비는 대체수요 및 신규수요를 합해 200여 대의 미니랩 장비가 설치됐으며, 이 중 향후 디지털을 접목시킬 수 있는 장비의 분포도가 약 $30\%$에 육박하고 있다. 민감하게 성장하고 있는 디지털화를 증명하고 있다고 볼 수 있다. 올해 각 업체별 판매목표는 1999년 지수의 $10\~15\%$ 이상을 상회할 것으로 예상되며, 2000년도 시장의 판도는 수요의 많고 적음을 떠나 디지털장

통계청(2000)은 1999년 9월 2일부터 9월 14일까지 13일간에 걸쳐 전국 약 17,000만 가구, 10세 이상의 가구원 42,973명을 대상으로 하여 ‘1999년 생활시간조사’를 실시한 바 있다. 통계청(2000)에 의하면 향후 5년 주기로 동 조사를 실시할 예정으로 있다. 이 조사는 우리나라 국민이 하루 24시간을 어떤 행태로 보내고 있는지를 조사함으로써 오늘의 국민들의 평균적인 생활방식과 삶의 질을 파악하고, 시간자원의 효율적 활용에 필요한 기초자료를 제공하는데 그 의의를 두고 있다. (중략)
