The discriminating power of journal evaluation criteria of Korean medical journals were measured. The study used the data of 76 medical journals, collected in the "Korean Medical Journal Evaluation" process conducted by the Korean Association of Medical Journal Editors (KAMJE) between 1997 and 1999. For each evaluation criterion, the distribution of the individual score vs the total score of a journal received was plotted and their correlations were analyzed. It is found that the evaluation criteria with a high discriminating power are the ones associated with the peer review system and the journal editing. The evaluation criteria with a low discriminating power are the journal frequency and how often a chief editor is changed. Some evaluation criteria such as "Journal holding rates of medical libraries" and "year-end index" need modifications in the evaluation methods. Other evaluation criteria such as "Journal self-citation rate","SCI citation rate" and "SCI impact factor" need to modify the score ranges. It is recommended that the new evaluation criteria such as "citation rate by Korean medical journals" and "Access availability of the journal information through major Korean medical abstract databases" should be added.formation through major Korean medical abstract databases" should be added.dded.

Residential complexes offer a sense of community and convenience, but making closed and privated space have been criticized.Closed urban spaces have issues encouraging residential segregation.large apartment complexes over 1,000 households,the most poular housing type in Korea, seems to make urban space more closed and privated than ever before. Our study puts forward and tests the hypothesis that large apartment complexes with over 1,000 households are linked to residential segregation. First of all, we examined the degree of residential segregation of metropolitan cities in Korea over a nine-year period (2011-2019). The dissimilarity index and the delta index were used for determining the extent of residential segregation. Next, we tested our hypothesis by Spearman's rank correlation analysis. Spearman's rank correlation analysis was performed on the residential segregation index per administrative division ("dong") and the number of large apartment complexes per administrative division ("dong").

This study aims to analyze electronic records research domains and trends and to suggest future direction of electronic records research in Korea. One hundred and sixty one articles published in seven domestic journals from 1999 to 2011 were statistically analysed to find out the productivity of electronic records research. Analysis of intellectual structure using descriptor profiling and author profiling as a technique of text mining were performed with those same papers. Some proposals on the future research direction in this field were made.

The geographical origin of red ginseng extract (RGE) was studied using a mass spectrometry based electronic nose. Imported RGE and domestic RGE were diluted to 12oBx. The treated RGE was analyzed, and discriminant function analysis (DFA) was used for discriminating of geographical origins. The DFA plots indicated a significant separation of imported RGE and domestic RGE. The F-value of discriminant function first score (DF1) was much higher than that of discriminant function second score (DF2), indicating that discrimination was mainly affected by DF1. Based on DF1, the concentration of domestic RGE to imported RGE shifted to the left side of DFA plot, and the mixing ratio highly correlated to DF1 value. Unknown sample (#2) was closely located to the sample of mixed imported : domestic (6:4) RGE. In the bar graph, the DF1 value correlated to the mixing ratio. Unknown samples (#2) were thought to be mixed with the imported RGE. This technique could be used to efficiently differentiate the geographical origin of RGE.

This study is to estimate the viability of aerobic stabilization technology for reducing greenhouse gas (GHG) emissions from landfills in Korea. In this study, methane emissions were estimated by applying Landfill gas estimation model (LandGEM) to Y landfill in Korea. By comparison of an anaerobic condition (baseline) and an aerobic condition, the amount of $CO_2eq$ savings was calculated. The $CO_2eq$ savings take place inside the landfilled waste during aeration due to the conversion of previously anaerobic biodegradation to aerobic processes, releasing mainly $CO_2$. It was demonstrated that 86.6% of the total GHG emissions occurring under anaerobic conditions could be reduced by aerobic stabilization technology. This means the aerobic stabilization technology could reduce environmental contamination through early stabilization and GHG emissions considerably at the same time. Therefore, the aerobic stabilization technology is one of the optimal technologies that could be employed to domestic landfill sites to achieve sustainable landfill.

21세기를 불과 몇 년 앞둔 우리 사회는 컴퓨터와 통신 등 정보통신기술의 발달로 인하여 정보사회로 급격히 이행하고 있으며, 우리나라도 정보화의 물결에 대응하기 위하여 국가적 차원에서 정보화 정책을 적극 추진하고 있다. 정부에서도 2000년까지 국가사회 전반의 획기적인 정보화 촉진을 위하여 '정보화 촉진기본계획'을 수립하였는데 그 중에는 지역정보화를 통한 지역균형발전과 지역격차해소, 나아가 지역주민의 삶의 질을 향상시키는 방안도 포함되어 있다. 지역정보화에 대한 연구는 '80년대 말부터시작이 되어 '90년대에 들어오면서부터 본격적인 연구가 시작되었은데 지역정보화가 도입된 초기에는 해외 선진국의 지역정보화 현황을 주관심사로 하여 지역정보화의 정책 및 지역정보화의 성공사례를 국내에 소개하는 것이 대부분이었으나 그 이후 국내 지역정보화의 현황, 지역정보화의 방안·추진전략, 그리고 지역정보시스템 구축 등 보다 구체적인 연구가 진행되어 왔다. 본 연구는 국내지역정보화의 연구동향을 분석하기 위하여 학술지, 세미나 및 학회, 그리고 연구과제 등으로 발표된 논문은 수집하여 연도별, 주제별, 그리고 연구 방법별로 분류하여 지역정보화의 연동향을 분석하였으며 연구동향 분석을 토대로 하여 장래의 연구방향에 대한 의견을 제시하였다.

The American bullfrog, Rana catesbeiana was imported from Japan for farming for the human consumption in 1970's and introduced populations were a great threat to native habitats in the pond and lake ecosystem. However, it is thought that the population of bullfrog has rapidly declined for past years in Korea. In this study, we investigated the intra-genetic diversity of R. catesbeiana habitated in Korea. The nucleotide sequences of 1,215bp mitochondrial ND1/tRNA region in bullfrogs sampled from 5 sites in Jeollanamdo were analyzed and compared to the original sequence of R. catesbeiara reported in Genbank. The nucleotide similarity between Korean and North American bullfrog was ranged from 98.7% to 100% based on kimura-2-parameter distance. In addition, bullfrogs analyzed in this study were clustered into two groups with one including Jangheung and the other including Gwangju populations in the neighbor-joining tree. North American R. catesbeiana was grouped in Jangheung cluster, indicating that there is the very low genetic difference between Korean and North American populations. The maximum parsimony tree in which North American R. catesbeiana was set as an outgroup suggests that Jangheung group represents the introduced population to Korea. Taken together, the results indicate that the population of R. catesbeiana in Korea has not segregated geographically yet, after the introduction.

In this study, we evaluated web usability for hospital web sites in Korea and analyzed the evaluation results of web usability. Estimators investigated twelve hospital web sites and answered a questionnaire. They also performed predefined tasks which were frequently used services in hospital web sites. We had an interview with the estimator for finding what happened in process of evaluating usability. The evaluation results showed that university hospital provided comparatively better web usability for users. But ambiguous and complicated user interface caused confusion among users. The simplifications of service processes and interfaces were necessary to improve web usability. Some hospitals did not offer primary web services and their services related to the tasks were not systematic.

제주도 서귀포시와 경북 안동시에서 사마풀속(Murdannia Royle)에 속하는 미기록 외래식물인 Murdannia nudiflora (L.) Brenan를 발견하여 보고하고자 한다. Murdannia nudiflora는 열대 아시아 원산으로 아프리카, 아메리카 대륙뿐만 아니라 우리나라와 가까운 일본에도 도입되어 있다. 종소명인 'nudiflora'는 본종의 조락하는 소포엽의 특징을 지칭하는 것으로 추정되며, M. nudiflora는 소포엽 외에 국내 자생하고 있는 사마귀풀[M. keisak (Hassk.) Hand.-Mazz.]과 뿌리, 꽃, 열매 및 종자의 외부형태로 쉽게 구분할 수 있다. M. nudiflora는 사마귀풀과 달리 뿌리줄기가 없고, 말단 혹은 액생하는 화서에 여러 개의 꽃이 피며, 꽃은 수술 2개, 헛수술 2-4개를 가지고, 열매는 자실 당 2개의 종자를 가지며, 종자는 작은 구멍이 있는 망상형 표면을 가진다. M. nudiflora는 닭의장풀과(Commelinaceae)에 속하는 분류군 중에서도 병해충을 유발하여 작물의 생산성을 감소시키는 잡초로 악명이 높으며, 주로 목화, 벼, 참깨 등과 같이 주요 작물이 재배되는 경작지에서 발견되는 것으로 알려져 있다. 본 종의 발견지들은 모두 해당 작물을 재배했던 것으로 추정되는 경작지로 M. nudiflora는 수입된 재배종 종자와 섞여 비의도적으로 도입된 것으로 보인다. 본 연구에서는 M. nudiflora의 화상자료 및 형태적 기재와 함께 국내 근연 분류군과 구별할 수 있는 검색표를 제시하고자 한다.
