Analyzing the relationships among the parameters for quantifying the quality of research published in journals is a challenging task. In this paper, we analyze the relationships between the impact factor, h-index, and g-index of a journal. To keep our analysis simple and easy to understand, we consider a generalized version of the impact factor where there is no time window. In the absence of the time window, the impact factor converges to the number of citations received per paper. This is not only justified for the impact factor, it also simplifies the analysis of the h-index and g-index as well because addition of a time window in the form of years complicates the computation of indices too. We derive the expressions for the relationships among impact factor, h index, and g-index and validate them using a given set of publication-citation data.

The aim of this study is to compare country output and citation impact as well as to assess the level of interdisciplinarity in the field of tribology research during the period 1998-2012, based on the SCOPUS database. Macro-level scientometric indicators such as growth rate, share of international collaborative papers, citation per paper, share of un-cited papers, and publication efficiency index were employed. Further, the Simpson Index of Diversity was used to measure the level of interdisciplinarity. The performance of top countries contributing more than 1000 papers during the study period was discussed. Contributions and share of continents and countries by income groups were examined. Further research contributions and citation impact of selected country groups were analyzed. This study reveals that high levels of interdisciplinarity exist in tribology research. Asia outperforms the other world regions and China contributes most of the papers (25%), while the United States receives most of the citations (22%).

Explicit reference to the work of other authors is an essential feature of most academic research writings. Corpus analysis of academic text can reveal much about what writers actually do and why they do so. Application of corpus tools in language education has been well documented by many scholars (Pedersen, 1995, Swales, 1990, Thompson, 2000). They demonstrate how computer technology can assist in the effective analysis of corpus based data. For teaching purposes, tills recent research provides insights in the areas of English for Academe Purposes (EAP). The need for such support is evident when students have to use appropriate citations in their writings. Using Swales' (1990) division of citation forms into integral and non-integral and Thompson and Tnbble's (2001) classification scheme, this paper codifies academic texts in a corpus. The texts are academic research articles from different disciplines. The results lead into a comparison of the citation practices m different disciplines. Finally, it is argued that the information obtained in this study is useful for EAP writing courses in EFL countries.

본 논문은 대학의 연구활동을 특허라는 창을 통하여 들여다보고자 하였다. 특허인용정보가 있는 미국 특허를 이용하여 우리나라의 대학 특허를 기업 특허와 대비시켜 대학 특허의 특성을 분석하였다. 일반적으로 기업 특허와 대학 특허는 전자는 전유성(appropriability) 측면에서 그리고 후자는 기초성(basicness) 측면에서 차이가 있는 것으로 본다. 그런데 기초성 측면에서 우리나라 대학 특허는 기업 특허와 크게 두드러진 차이를 보이지 않는 것으로 나타났다. 다음으로 특허인용함수모형을 이용하여 특허의 질 또는 수준을 기업과 대학 사이에 비교해 보았다. 기업 특허는 자체인용이 상당수 포함되어 있는데, 이를 감안하면 전방인용에 있어서는 대학 특허와 기업 특허는 큰 차이를 보이지 않는 것으로 나타났다. 자체인용 비중이 높을수록 특허의 전유성 정도가 높은 경향이 있다는 선행연구를 상기하면, 기업 특허의 전유성 정도가 높게 나오는 것을 확인할 수도 있었다. 미국과 유럽을 대상으로 한 선행연구에서는 대학 특허가 대체로 기업 특허와 비교하여 인용빈도 측면에서 뒤지지 않는 것으로 분석되고 있다. 외국의 대학 특허 분석결과와 본 논문의 우리나라 대학 특허 분석결과를 대비시키면, 우리나라 대학 특허는 전반적인 수준이나 영향력 측면에서는 기업 특허에 미치지 못하며, 이는 우리나라대학의 특허활동이 최근에야 활성화된 데 기인한 것으로 추론된다. 이러한 분석 결과는 향후 대학의 연구수준을 제고하기 위한 노력을 보다 체계화해야 한다는 것을 시사하며, 최근 진행되고 있는 정부의 기초연구 정책방향 전환이나 대학 내의 자체적인 개혁 움직임을 간접적으로 지지한다. 정부의 정책 전환과 함께 학내의 개선 노력이 합치되면 향후 우리나라 대학의 특허인용도 및 영향력이 훨씬 높아지게 될 것으로 기대할 수 있다.

The academic research performance is often quantitatively measured by means of using citation frequency. The citation frequency-based indicators, such as h-index and impact factor, are commonly used reflecting the citation quality to some extent. However, these frequency-based indicators are usually carried out based on the assumption that all citations are equal. This may lead to biased evaluations in that, the attributes of the citing objects and cited objects are significant. A high-accuracy evaluation method is needed. In this paper, we review various citation quality-based evaluation indicators, and categorize them considering the algorithms being applied. We discuss the pros and cons of these indicators, and compare them from four dimensions. The outcomes will be useful for our further research on distinguishing citation quality.

인용분석은 학자들의 연구실적 평가에 가장 많이 사용되는 방법 중 하나이지만 비평가들은 오늘날의 인용분석 자료와 방법론에 근본적인 문제가 있다고 주장한다. 전통적 인용분석 방식은 인용품질과 인용소음뿐만 아니라 언어, 시간, 문화와 같은 비수치적인 요소들을 고려하지 않아 단순하고 그릇된 평가를 가져올 수 있으며, 적용 범위가 각각 다르고 불완전한 인용 데이터베이스들은 충돌적인 인용분석결과를 초래하기 쉬울 수 있다. 이러한 문제들을 해결하려면 포괄적인 인용데이터를 다 방면과 다 방식으로 분석하는 새로운 인용분석연구가 필요하다. 본 논문은 Web of Science, Scopus와 Google Scholar를 비교 분석한 연구의 결과를 논의하며 기존의 인용분석 방법의 약점을 극복하기 위해 설계한 CiteSearch라는 프로토타입 시스템을 간략하게 설명한다.

Technology used by human beings has developed drastically over the years. Although people enjoy affluent lives as a result of this development, the depletion of resources has brought about a variety of environmental problems such as emission of fine dust, treatment of waste water, and global warming. Although studies on environmental pollution are being conducted continuously, there are a limited number of studies that analyze research trends from quantitative and qualitative perspectives. In order to examine the current research landscape, we employed Scopus to combine research interest in environmental science with bibliographic analysis. Among 74,089 papers published in 57 journals of environmental science, 3,212 papers were published by Korean authors and citations per publications and Field-Weighted Citation Impact (FWCI) of those papers were 7.3 and 1.0, respectively. By assessing the bibliometric indicators in the field of environmental science, this study provides insight into research trends and related data to aid researchers in developing research strategies.
