Despite extensive research, performance enhancement of keyphrase (KP) extraction remains a challenging problem in modern informatics. Recently, deep learning-based supervised approaches have exhibited state-of-the-art accuracies with respect to this problem, and several of the previously proposed methods utilize Bidirectional Encoder Representations from Transformers (BERT)-based language models. However, few studies have investigated the effective application of BERT-based fine-tuning techniques to the problem of KP extraction. In this paper, we consider the aforementioned problem in the context of scientific articles by investigating the fine-tuning characteristics of two distinct BERT models - BERT (i.e., base BERT model by Google) and SciBERT (i.e., a BERT model trained on scientific text). Three different datasets (WWW, KDD, and Inspec) comprising data obtained from the computer science domain are used to compare the results obtained by fine-tuning BERT and SciBERT in terms of KP extraction.

This study analyzed the kinds and frequencies of descriptors in 154 articles in ERIC data base on the 4th day of January in 2010. The titles of the articles includes the words, 'scientific literacy'. As each descriptor is constituted of two words and over, in this study the first word in the descriptor was defined as 'restrictive word' and the rest word(s) as 'target word(s)'. The results are as follows. First, the descriptors which show high frequencies of target words are the traditionally important themes of scientific literacy education. Target words which show relatively high frequency are 'education', 'literacy', 'instruction' and 'countries'. Low frequency word is 'curriculum', which has various restrictive words and represents wide differentiation. Second, among the descriptors which show low frequencies of target words, relatively high frequency descriptors are '(and)society', 'change', 'secondary education', 'concepts', and 'biology', which have been given more attention in scientific literacy research than the rest descriptors. Third, the number of the descriptors that shows largely distributed pattern A, which happens over 15 years continuously, is over the half of all analyzed descriptors, which shows that they have been the major objectives in researches about scientific literacy. Most descriptors of pattern A shows normal distribution of frequency or the trends of increasing frequency as the time is nearer. Fourth, The descriptors are divided into four groups according to the time span. Each research trends are as follows. In later 80s, the research which emphasizes the importance of the sociality and technology in all level school science curriculum. In later 90s the research for educational change of inquiry-centered science curriculum which considers technological literacy in social contexts. In earlier 2000s the research that scientists and science teachers develop science curricula mostly related to scientific principles and thinking in chemistry and biology especially. In later 2000s case studies which relates teaching methods and science process activities to students' attitudes, scientific concepts and curricula.

본 연구는 1960년대 이후 과학적 소양을 정의하고 분류를 시도했던 연구자들의 분류 결과를 3가지 분류 기준에 의하여 재분류하고, 과학적 소양의 정의 분류의 경향을 파악하는데 목적이 있다. 과학적 소양이 과학교육의 주요 목표를 대변하는 개념이므로 그 정의에 따른 분류는 과학교육의 목적에 대한 동향을 검토할 수 있는 주요자료가 될 수 있다. 분류 기준은 1) "literate"의 의미로서 '학습됨', '능력 있음', '사회에서 최소 기능을 할 수 있음', 2) 과학적 소양을 표현하는 방식으로서 용어와 서술, 3) 과학적 소양의 내부 구조로서 '단일 구조', '직렬식 위계구조', '병렬식 수평구조'이다. 분류 결과와 해석은 다음과 같다. 첫째, 과학적 소양의 구조로서 위계 구조는 90년대 후반부터 표현방식으로서 용어를 사용하는 정의와 함께 나타나고 있으며, 학습과 능력사이에서만 위계를 인정하고 사회적 기능으로서의 과학적 소양의 의미는 수용하지 않고 있다. 수평구조는 과학적 소양의 하위 요소 간의 위계 구조를 보이지 않는 대신 사회적 기능으로서 과학적 소양의 의미를 전반적으로 수용하고 있다. 또, 단일 구조는 대부분 과학적 소양을 새로운 시각에서 제안하는 연구에서 나타나고 있으며, 소양의 의미도 최근으로 오면서 학습에서 능력을 거쳐 사회적 기능을 강조하는 특성이 있다. 둘째, 근래로 오면서 과학적 소양을 용어 형식으로 정의하려는 연구가 증가하고, 이들 사이에도 위계를 설정하는 분류가 주도하고 있다. 또한 소양의 세 가지 의미인 학습, 능력, 사회적 기능을 전반적으로 수용하는 분류가 빈번해졌으나, 이들 간에는 위계 구조보다는 오히려 수평 구조를 설정하는 경향이 있다. 위와 같은 분석 결과를 토대로 살펴 볼 때, 과학 교육의 목표로서 과학적 소양의 의미는 학습이나 과제 해결 능력뿐만 아니라, 근래에는 사회적 맥락에서 어떤 역할을 하는 개인을 육성하려는 목표로서 인정되고 있다는 점이다. 또한 주목할 것은 과학적 소양의 이러한 사회적 기능 측면은 위계적이 아닌 독립적인 목표로서의 특성을 견지하고 있다는 점이다. 이러한 변화에 능동적으로 대처하기 위해서는 과학교육이 교과 내 개념학습에서 벗어나 다양한 맥락에서의 적용과 사회적 역할을 중시하는 목표로 전환할 준비를 해야 할 것으로 보인다.

The purpose of this study was to develop instructional strategy for newspaper-based science writing and to examine the effect of its application. The target unit was 'change of weather' and 'a variety of gas' in the sixth grade of elementary school, and the teaching strategy was composed of 3 stages-writing including realistic, interpretative and comprehensive writing. The result of applying this strategy into actual classrooms was as follows. First, it was proven that the science writing strategy using newspaper articles actually helped improving science process skills of learners, in particular, integrated process skills. Second, this strategy for science writing changed the scientific attitude of learners positively. While they read the newspaper articles, their thinking became more elaborate and systemized, which seemed to serve to foster their openness, criticism, and perseverance. Third, the science writing strategy did not contribute to the improvement of learners' science study achievement. To improve the understanding of scientific concepts and principles of learners, it is needed that teaching program combines with argument-based activity organically. The above-mentioned findings show that this instructional strategy using newspaper articles can be applicable as one of effective methods in science writing.

Objectives: By analysing the recent trends of published papers in the Korean Journal of Health Education and Promotion, this study aims to identify and discuss some challenging issues, and to provide recommendations for quality improvement of the research papers. Methods: One hundred and sixty five papers published between 2009 and 2011 were examined and categorized according to selected standards. Results are displayed in frequencies and percentages. Results: The volume of articles published has increased by two-folds in three decades since the publication of the first issue. More than 90% of the papers were original articles. Cross-sectional research design was most frequently applied, while only 11.5 % of the articles were intervention studies. For cross-sectional research articles, limitation in generalizability of the study findings was mentioned as one of the major issues, in relation with the frequent use of convenient sampling methods and lack of theoretical evidence in inclusion of variables. Consideration of internal and external validity of the study, utilization of scientific evaluation design and mixed evaluation methods were recommended for intervention research to improve the quality of the research results. Conclusion: To serve as a key resource for evidence-based practices in health promotion, more strict scientific research criteria should be applied to the articles published in the Korean Journal of Health Education and Promotion.

Given the difference in research performance in various scientific fields, this study aims to weight and valuate current indicators used for evaluation of scientific productions (publications), in order to adjust these indicators in comparison to each other and make possible a more precise evaluation of scientific productions. This is a scientometrics study using documentary, evaluative, and survey techniques. The statistical population consisted of 106 top Iranian researchers, scientists, and scientific and research managers. Then their research résumé information was gathered and analyzed based on research questions. In order to compare values, the data gathered from research production performance of the population was weighted using Shannon entropy method. Also, the weights of each scientific production importance according to expert opinions (extracted from other works) was analyzed and after adjustment the final weight of each scientific production was determined. A pairwise matrix was used in order to determine the ratios. According to the results, in the area of engineering sciences, patents (0.142) in the area of science, international articles (0.074) in the area of humanities and social sciences, books (0.174), and in the area of medical sciences, international articles (0.111) had the highest weight compared to other information formats. By dividing the weights for each type of publication, the value of each scientific production compared to other scientific productions in the same field and productions of other fields was calculated. Validation of the results in the studied population resulted in very high credibility for all investigated indicators in all four fields. By using these values and normalized ratios of publication indicators it is possible to achieve precise and adjusted results, making it possible to feasibly use these results in realistic policy making.
