The study aims to analyze key issues and research trends in international research on the digital inequality of immigrants. Based on a total of 401 articles on digital inequality of immigrants published in Web of Science registered journals between 2000 and February 2023, the authors identified key research topics. The analysis reveals an increasing number of articles on immigrants’ digital inequality, starting with two articles in 2006, and showing a sharp increase since 2020. Research areas on the digital inequality of immigrants are led by various academic fields, including social science, medicine, and multidisciplinary studies. Five topics were identified through topic modeling and word network analysis: ‘immigrants’ digital inequality in health’, ‘COVID-19 and immigrants’ digital inequality’, ‘Immigrants’ digital inequality in education’, ‘Immigrants’ inequality in the digital age’, and ‘Digital inequality of migrant workers’. It was shown that topics of ‘immigrants’ digital inequality in health’ and ‘Immigrants’ inequality in the digital age’ have been attracting significant attention.

This paper identifies research trends in real estate and explores future real estate research topics. For this purpose, bibliometric analysis was conducted using VOSviewer and R on bibliographic information from 208,648 real estate-related research papers indexed in the Web of Science database. The study analyzed and visualized keyword co-occurrence patterns, international research collaboration networks, the temporal evolution of research topics, and research performance by field and country. The analysis identified five major domains: 'land, buildings, housing, real estate, and property technology (proptech),' with the corresponding main research fields being 'environment, architecture, housing, economics, and engineering.' The world's major research topics include 'biodiversity, architectural design, well-being, standard pricing, and performance management', while emerging research topics encompass 'climate change, change detection, shared housing, price prediction, and advanced management'. Notably, 42% of all research was conducted primarily by the United States, China, and the United Kingdom, with research conducted after 2020 accounting for 50% of all studies, and South Korea ranked 16th globally with 4,355 research papers. These trends suggest that real estate research is expanding beyond traditional areas such as civil engineering, architecture, energy, and residential environment studies, into new value-creating domains including environmental, social, and governance (ESG), financial innovation, and digital transformation.

This bibliometric study is a citation analysis of journals that concern themselves with businessrelated topics. For this purpose, the journals from the following five categories from the Web of Science Subject Categories have been examined: “Business”, “Business & Finance”, “Economics”, “Management” and “Operations Research & Management Science”. The data is retrieved from the Journal Citation Reports 2019 for each journal that is part of one of the categories. The data includes information about the journals that the articles published in the specific journal in 2019 cited and which journals cited the articles in a specific journal (Cited Journal Data and Citing Journal Data). This data is combined by creating an asymmetrical 1- mode matrix of all journals. Then, the matrix is analyzed with Pajek and VOSviewer to create clusters of journals with a high inter-correlation through citations. In the following step, the journals in these clusters are analyzed for their disciplines, main topics, and compared to typical fields of study at universities (e.g. Accounting, Marketing, Finance, etc.) in order to highlight similarities and differences between the fields of studies and the clusters of journals.

This study carries out a bibliometric analysis to uncover the gap between global and local research trends in translation and interpreting. The research analyzes papers on translation and interpreting published between 2015 and 2019 in the Web of Science (WoS) and Korea Citation Index (KCI). First, the paper identified publication activities, geographic distributions, and research areas in WoS and KCI. Second, the paper conducted keyword network analysis and visualization. The result shows that the number of links and total link strengths of KCI recorded only 1/10 and 1/8 of WoS, respectively, indicating weak linkage between keywords in KCI papers. In particular, comparison of top 20 keywords between WoS and KCI reveals that research themes in KCI are less diverse than those in WoS, mostly focusing on translation strategies. Unlike previous bibliometric research in Korean translation studies that analyzed only translation studies journals, this paper analyzed all journals indexed by WoS and KCI and employed keyword network analysis and visualization for more comprehensive and objective description of research trends in and outside of Korea.

Purpose: The present study analyzed the current status of the data sharing policies of journals published in Brazil, France, and Korea that were listed in the 2018 Scimago Journal and Country Ranking and Web of Science Core Collection. Methods: Web of Science journals were selected from the 2018 Scimago Journal and Country Ranking. The homepages of all target journals were searched for the presence of statements on data sharing policies, including clinical trial data sharing policies, the level of the policies, and actual statements of data availability in articles. Results: Out of 565 journals from these three countries, 118 (20.9%) had an optional data sharing policy, and one had a mandatory data sharing policy. Harvard Dataverse was the repository of one journal. The number of journals that had adopted a data sharing policy was 11 (6.7%) for Brazil, 64 (27.6%) for France, and 44 (25.9%) for Korea. One journal from Brazil and 20 journals from Korea had adopted clinical trial data sharing policies in accordance with the International Committee of Medical Journal Editors. Statements of data sharing were found in articles from two journals. Conclusion: Journals from France and Korea adopted data sharing policies more actively than those from Brazil. However, the actual implementation of these policies through descriptions of data availability in articles remains rare. In many journals that appear to have data sharing policies, those policies may just reflect a standard description by the publisher, especially in France. Actual data sharing was not found to be frequent.

Purpose: This study analyzed the bibliometric characteristics of flipped classroom publications in the Social Science Citation Index and Science Citation Index Expanded from 2000 to 2019. Methods: The terms related to “flipped classroom” and “inverted learning” were the keywords for searching journal articles on January 3, 2020. Results: There are 645 articles (including 33 early-access articles), representing 1,938 authors in the 210 journals scanned. The United States, China, and Taiwan were three leading countries/regions in this field. In the top 10 countries, to 10 institutions, the top eight most-cited journals were identified by either the number of publications or the number of citations. Hot-spot themes from the 24 highly-cited articles and author keyword co-occurrence analysis focus on empirical research in the flipped classroom, the overall feasibility of the flipped classroom course design and practical model, and students’ performances, and student-regulated learning (active learning and readiness) outcomes. Conclusion: TThe results indicate that the United States dominated flipped classroom research, originating most of the highly-cited articles, having more prolific authors, and presenting the most-cited institutions. Furthermore, little research has been undertaken into arriving at an understanding of evidentiary effectiveness or consistency in a flipped classroom. Based on the trends identified, we need a call for more specific types of research into the effectiveness of flipped classroom studies and systematic reviews.

Purpose This study analyzed the bibliometric characteristics of publications on inclusive education in the Social Science Citation Index and Science Citation Index Expanded in the Web of Science Core Collection from 1992 to 2020. Methods Terms related to “inclusive education” and “inclusion of education” were used as keywords to search for journal articles on July 3, 2020. Results There were 1,786 articles, representing 3,376 authors, in the 345 journals scanned. The United States, United Kingdom, and Australia were the three leading countries/regions in this field. In the top 12 countries, the top 15 institutions and the top 10 most-cited journals were identified by either the number of publications or the number of total citations. Core themes from the 30 most highly-cited articles were teachers’ attitudes, teachers’ self-efficacy, and the effects of inclusive education. Teachers included both pre-service and in-service teachers; students represented those with and without special educational needs. Conclusion The results indicate that the United States, United Kingdom, and Australia dominated inclusive education research, originating most of the highly-cited articles, having more prolific authors, and presenting the most-cited institutions. Furthermore, three emerging core themes from the 30 most highly-cited articles were teachers’ attitudes, teachers’ self-efficacy, and the effects of inclusive education. Frontline teachers are recommended to submit manuscripts about their teaching experiences to the most-cited journals, which have a large readership. To measure the effects of inclusive education, it is essential to formulate reliable, valid, and culture-free research instruments for future studies.

The aim of this study was to analyze the bibliometric characteristics of publications from North Korea indexed in the Web of Science Core Collection from 1988 to 2016. We hypothesized that the main research area would be the physical sciences, and that the number of articles would continually increase over time. The Web of Science Core Collection was searched using the terms “North Korea” OR “Democratic People’s Republic of Korea” OR “DPRK” in the address field of the basic search on February 2, 2017. The country of the co-authors, affiliations, journals, annual number of publications, and research fields were analyzed. Additionally, the articles by North Korean authors only were analyzed for the same parameters. A total of 318 articles from North Korea were found. The most frequent countries of collaboration were China, Germany, and Australia. Kim Il Sung University produced the most articles. The main research fields were physics, mathematics, and materials science. The categories of the journal titles corresponded to the research fields. The rapid increase in the number of articles in 2015 and 2016 was remarkable, although this increase started from a very small baseline number of publications. The results of the analysis of the 46 articles published by North Korean authors only were equivalent to the results for the 318 articles presented above. Our hypotheses were confirmed. The surge of articles in 2015 and 2016 may represent the recent efforts by the North Korean government to emphasize scientific research and development. It is anticipated that the productivity of North Korean researchers in terms of publications in international journals will increase dramatically based on the above trends, although the publication baseline is very low.

This study presents an update of a previous study, ‘Bibliometric analysis of publications from North Korea indexed in the Web of Science Core Collection from 1988 to 2016,’ which was published in Science Editing volume 4, issue 1. A re-analysis was performed because an incomplete search strategy was used in the original publication, and the present study analyzed the same bibliometric characteristics of publications from North Korea indexed in the Web of Science Core Collection from 1978 to 2018. The Web of Science Core Collection was searched by selecting ‘North Korea’ in the country field of the basic search results on July 31, 2018. A total of 533 articles were identified. There were no results from before 1978. China, Germany, and Australia were main countries of collaboration. Researchers from Kim Il Sung University produced the most articles. The main research fields were physics, mathematics, materials science, chemistry, and engineering. The funding agencies were mostly from China. The number of articles by North Korean authors only was 105, with the same main research fields. The results were almost the same as reported in the previous article, except for a much higher number of publications. The above results indicate that the North Korean government has asked researchers to publish their works in international journals; therefore, it has allowed them to access the internet. Based on the trends we identified, we anticipate that there will be a continuous increase in publications from North Korea in international journals indexed in the Web of Science Core Collection.

Purpose: The open access (OA) movement has significantly improved access to academic content. However, the financial burden of article processing charges (APCs) and the lack of pricing transparency remain major concerns. This study aims to estimate APC costs by publisher and country, focusing on Korea, to inform policy decisions. Methods: We combined datasets from ScholCommLab (2019?2023), KESLI (2018?2024), and Web of Science (WoS). These sources were merged by aligning APC data with WoS-indexed articles, adjusting for missing values and currency differences. The final dataset included over 4.4 million records, enabling detailed analysis of APC expenditures by publisher and country. Results: From 2019 to 2023, global APC spending increased, with clear regional disparities. Italy showed the highest compound annual growth rate in APC costs at 34.17%, followed by moderate to high growth in Korea, Germany, and the United Kingdom. Korea and Italy allocated large proportions of APC spending to MDPI?38.71% and 37.53%, respectively?raising concerns about publisher dominance and potential quality issues. In contrast, Germany and the United Kingdom established national agreements aimed at controlling APC costs. Conclusion: This study underscores the growing global burden of APCs and the need for costmanagement strategies. Policymakers should consider targeted financial support and promote equitable publishing models. Adoption of the diamond OA model?which removes APCs for authors and provides free access to readers?offers a sustainable and inclusive path forward for academic publishing, addressing both financial and ethical challenges in the current OA landscape.

Purpose The aim of this study was to characterize the network of institutions, journals, and topics of coronavirus disease 2019 (COVID-19) literature by Korean authors in the Web of Science Core Collection. The specific goals were to identify the collaborative relationships between Korean authors and international authors and to explore clusters of institutions, journals, and topics. Methods Literature was searched in the Web of Science Core Collection on January 30, 2021. The search terms were “SARS-CoV-2” or “COVID” or “novel coronavirus” in the subject field. The search results were limited again to “South Korea” as the country and the publication type of “article.” The measurement tool was Biblioshiny, an app version tool for Bibliometrix. Results Korean authors published 3.2 times more COVID-19?related articles in journals outside of Korea than in Korean journals. The journals showed three clusters by bibliographic coupling. In contrast, the co-citation network showed four clusters. Only a few journals were included in the clusters in both analyses. The conceptual structure of Keywords Plus by factorial analysis showed two clusters: “pathology and clinical treatment” and “knowledge and attitudes.” Institutions’ collaborative network consisted of four clusters. Korean researchers actively collaborated with international researchers, especially those in the United States. Conclusion Because only a few Korean journals were included in the journal clusters by both coupling and co-citation network, more active citation of Korean journals is recommended. The identification of human behavior as a distinct theme in COVID-19 research suggests a different focus in this area besides clinical studies.

Purpose: This study analyzed retracted articles in nutrition and dietetics using bibliometric methods to identify their characteristics, trends, and reasons for retraction, thereby enhancing transparency and scientific credibility in the field. Methods: A bibliometric study was conducted using the Web of Science database to extract retracted articles in nutrition and dietetics without time or language restrictions in November 2024. The search strategy targeted the categories “nutrition & dietetics” and “retracted publication.” Additional data on retraction reasons were collected from the Retraction Watch database. Author-level indicators (e.g., number of authors, countries) and document-level indicators (e.g., publication trends, citations, retraction reasons) were analyzed. VOSviewer was used for keyword co-occurrence analysis, and descriptive statistics provided quantitative insights. Results: Between 1997 and 2023, 105 retracted articles were identified, authored by 523 researchers, and collectively cited 3,171 times. The United States and China led in the number of retractions (26.7% and 17.1%, respectively). Misconduct was the leading reason for retraction (87 articles, 82.9%), but 48 articles (45.7%) had no reason reported. Journals classified in the Q1 and Q2 categories accounted for most retractions, and 46.7% of the articles had funding. Keyword analysis revealed four clusters focused on public health, biomedical mechanisms, experimental research, and nutritional compounds. Conclusion: Although the overall number of retracted articles in nutrition and dietetics remains limited, scientific misconduct and insufficiently reported retraction reasons present ongoing challenges to the integrity of the literature. Improved citation practices and greater transparency in retraction reporting are essential to protect public health and maintain scientific trust.

Purpose: The ultimate goal of current open access (OA) initiatives is for library services to use OA resources. This study aimed to assess the infrastructure for OA scholarly information services by tabulating the number and proportion of OA articles in a literature database. Methods: We measured the absolute numbers and proportions of OA articles at different time points across various disciplines based on the Web of Science (WoS) database. Results: The number (proportion) of available OA articles between 2000 and 2021 in the WoS database was 12 million (32.4%). The number (proportion) of indexed OA articles in 1 year was 0.15 million (14.6%) in 2000 and 1.5 million (48.0%) in 2021. The proportion of OA by subject categories in the cumulative data was the highest in the multidisciplinary category (2000?2021, 79%; 2021, 89%), high in natural sciences (2000?2021, 21%?46%; 2021, 41%?62%) and health and medicine (2000?2021, 37%?40%; 2021, 52%?60%), and low in social sciences and others (2000?2021, 23%?32%; 2021, 36%?44%), engineering (2000?2021, 17%?33%; 2021, 31%?39%) and humanities and arts (2000?2021, 11%?22%; 2021, 28%?38%). Conclusion: Our study confirmed that increasingly many OA research papers have been published in the last 20 years, and the recent data show considerable promise for better services in the future. The proportions of OA articles differed among scholarly disciplines, and designing library services necessitates several considerations with regard to the customers’ demands, available OA resources, and strategic approaches to encourage the use of scholarly OA articles.

본 연구는 2005년 1월부터 2025년 12월까지 Web of Science 핵심 컬렉션(SCI, SSCI, ESCI) 에 등재된 국제학술지에 발표된 알코올, 약물, 다중중독 집단 대상 예술치료의 임상 효과를 체 계적 문헌고찰 및 메타분석을 통해 검토하였다. Web of Science 데이터베이스를 중심으로 총 1,159편의 논문이 1차 검색되었으며, PRISMA 기준에 따라 최종 17편이 분석에 포함되었다. 통 합 표준화 효과크기(g)는 -0.51(95% CI: -0.62∼-0.41, p<.001)로, 대조군 비교 연구 및 단일군 전후 비교 연구 모두에서 예술치료 개입 후 임상 및 심리사회적 지표의 유의한 개선이 관찰되 었다. 하위 분석에서는 정서/불안(g=-0.56, 95% CI: -0.69∼-0.43), 중독 증상(g=-0.48, 95% CI: -0.59∼-0.36) 요인에서 모두 임상적 개선이 나타났다. 개별 중재 유형별로는 미술치료 (g=-0.50, 95% CI: -0.67∼-0.32), 음악치료(g=-0.53, 95% CI: -0.71∼-0.35), 연극치료(g=-0.49, 95% CI: -0.62∼-0.35), 동작치료(g=-0.43, 95% CI: -0. 70∼-0.16) 모두 통계적으로 유의한 효 과를 보였다. 효과의 민감도 분석(전체: g=-0.51, 극단값 제외: g=-0.50, 질 낮은 연구 제외: g=-0.54), 출판편향 검증(Egger 회귀계수 p=0.21, Begg 순위상관 p=0.27) 결과에서도 일관성과 신뢰성이 확인되었다. 본 연구는 예술치료가 중독 집단에서 심리 사회적 회복을 촉진할 뿐 아 니라, 근거 기반 중독 치료 체계에서 예술치료 통합의 필요성을 시사한다.

This study presents a systematic review and meta-analysis of clinical trials evaluating arts-based interventions for individuals with alcohol, drug, or polysubstance use disorders, published between January 2005 and December 2025 in international journals indexed in the Web of Science Core Collection (SCI, SSCI, ESCI). A database search yielded 1,159 records, of which 17 studies met predefined eligibility criteria in accordance with PRISMA guidelines. The pooled standardized mean difference (Hedges’ g) was -0.51 (95% CI: -0.62 to -0.41, p<.001), indicating a moderate overall effect of arts therapies on clinical and psychosocial outcomes across randomized controlled trials and pre–post single-group designs. Subgroup analyses showed significant benefits for emotional and anxiety-related outcomes (g=-0.56, 95% CI: -0.69 to -0.43) and for addiction-related indicators such as substance use, craving, and relapse (g=-0.48, 95% CI: -0.59 to -0.36). When stratified by intervention modality, all examined approaches demonstrated statistically significant effects, including art therapy (g=-0.50, 95% CI: -0.67 to -0.32), music therapy (g=-0.53, 95% CI: -0.71 to -0.35), drama therapy (g=-0.49, 95% CI: -0.62 to -0.35), and movement-based therapy (g=-0.43, 95% CI: -0.70 to -0.16). Sensitivity analyses produced consistent estimates (g ranging from -0.50 to -0.54), and tests for publication bias (Egger’s regression p=0.21; Begg’s rank correlation p=0.27) did not indicate substantial small-study effects. Overall, these findings suggest that arts-based interventions support psychosocial recovery among individuals with substance use disorders and underscore the value of incorporating arts therapies into evidence-based addiction treatment.

세계화와 디지털 전환이 가속화되는 상황에서 동아시아 경제체는 기술 공급과 수요의 불균 형, 인구 고령화, 청년 실업률 상승 및 비정규 고용 확대 등 노동시장의 도전에 직면해 있다. 본 연 구는 CiteSpace 소프트웨어를 이용하여 Web of Science와 CNKI 데이터베이스의 문헌에 대한 키워드 클러스터링과 지식 도감 분석을 실시하는 문헌계량 분석 방법에 기초한다. 연구 결과 국제 연구는 사회 경제 정책 개입, 직업 심리 건강, 직업 복지 등의 주제에 초점을 맞추고 있는 반면, 중국 국내 연구는 디지털 경제 취업 잠재력 활성화와 혁신 직업 교육 체계의 현지화 특징을 강조한다. 게다가 문헌의 수는 기하급수적으로 증가하고 있지만, 지역적 편중과 학술 공동체의 분리 문제가 있다. 이 를 바탕으로 이 글은 미래 연구 방향을 제시한다: ① 이론-실천이 결합된 취업품질 평가 프레임워크 구축; ② 디지털 경제가 노동 형태에 미치는 영향 메커니즘을 해석한다. ③ 지역적 한계를 돌파하기 위해 다국적 비교연구를 강화한다.

Amid accelerating globalization and digital transformation, East Asian economies face labor market challenges such as technological imbalances, aging populations, rising youth unemployment, and expanding informal employment. This study employs bibliometric analysis with CiteSpace to examine keyword clustering and knowledge graphs from Web of Science and CNKI databases. Results show international research focuses on socio-economic policy intervention, occupational mental health, and work well-being, while Chinese research emphasizes activating digital economy employment potential and innovating vocational education systems. Despite exponential growth in publications, regional bias and academic fragmentation persist. Future research should:①develop integrated employment quality frameworks,③ analyze the digital economy’s impact on labor forms, and② enhance cross-national comparative studies.

This study examines Web of Science-indexed Jane Austen-related publications from 1995 to 2025. Based on 602 English-language records from the Web of Science Core Collection, it analyzes annual publication growth, country-level citation visibility, source productivity, and keyword-based thematic change. The study does not claim to represent the whole of global Austen scholarship. Rather, it maps patterns of indexed visibility within a defined WoS corpus. The results show that Austen-related publications increased over the period, with an annual growth rate of 10.68%, although the 2025 records reflect indexing up to September 7, 2025. Citation visibility is concentrated mainly in the United States and the United Kingdom, while international co-authorship remains limited. Keyword-based analyses suggest a shift from author-centered and narratological terms toward broader themes, including history, feminism, adaptation, fiction, gothic, language, and comparative literary reference. These findings indicate expansion and diversification rather than the replacement of earlier concerns. By tracing publication trends and thematic change, the study offers a reproducible overview of how Jane Austen-related research has appeared within the WoS-indexed record.

본 연구는 2019–2024년에 출판된 Web of Science Core Collection 논문 948편을 대상으로, KW_Merged(Author Keywords ∪ Keywords Plus)에 기반한 단일 파이프라인(association-strength 정규화, Louvain 군집, Fruchterman– Reingold 레이아웃)에서 키워드 공출현 네트워크, 중심성–밀도 전략도, 2기 테마 진화(2019–2021 → 2022–2024)를 일관되게 산출하였다. 분석 결과, 지적 구조는 방법–시스템/설계–응용의 세 블록으로 응집되며 convergence가 이들 간을 매개한다. 전략 도는 핵심 허브의 지속성과 함께 주변부 마이크로 테마의 AI·지속가능성 축을 따른 재배치를 보여 주며, 계산 중심 주제(모델링· 시뮬레이션·최적화)에서 데이터 집약적 지능 및 지속가능 시스템(머신러닝·컴퓨터 비전·딥러닝·에너지 효율·스마트 그리드)으로 의 점진적 이동을 시사한다. 테마 진화는 algorithm–convergence–design 축의 직접적 지속(포함지수 ≥ 0.30), consensus protocol과 multi-objective optimization의 유입(응용 확장 경로), finite element와 voltage control 계열의 주변화 경향을 확인한다. 해석은 임계값을 달리한 간단한 점검(min occurrence 3/5/7; 포함지수 경계 조정)에서도 안정적으로 유지되었다.

This study maps convergence in engineering using a reproducible single-parameter pipeline applied to 948 Web of Science Core Collection records published between 2019 and 2024. The analysis relies on the KW_Merged field (Author Keywords ∪ Keywords Plus) and jointly estimates a keyword co-occurrence network, a centrality–density strategic map, and a two-period thematic evolution (2019–2021 → 2022–2024) under association-strength normalization, Louvain community detection, and a Fruchterman–Reingold layout. The intellectual structure consolidates into three blocks—method, system/design, and applications—with convergence brokering across them. Strategic-map evidence shows persistent core hubs, while peripheral micro-themes emerge and reposition along an AI- and sustainability-oriented axis, indicating a gradual shift from computation-centric topics (modeling, simulation, optimization) toward data-intensive intelligence and sustainable systems (machine learning, computer vision, deep learning, energy efficiency, smart grids). Thematic evolution highlights the direct continuity of the algorithm–convergence–design axis (inclusion ≥ 0.30), the inflow of consensus protocol and multi-objective optimization as routes of application-level expansion, and a relative decline of finite-element and voltage-control families toward the margins. Interpretations remain stable under compact threshold checks (minimum occurrence 3/5/7; adjusted inclusion cutoffs), supporting robustness.

본 연구의 목적은 과학기술분야 웹 정보원의 평가기준을 제시하고 평가 기준간의 관계를 규명하는 것이다. 웹 정보원 평가 카테고리로서 정보 콘텐츠, 기능성, 그리고 디자인 등 세 가지가 제시되었다. 정보 콘텐츠는 권위성, 적합성, 최신성을, 기능성은 탐색성, 네비게이션, 이용자 지원성을, 그리고 디자인은 구조 및 외양 등의 평가 요소를 포함한다. 제시된 평가 기준에 근거하여 과학기술 주제분야별로 총50개 웹 정보원을 평가한 결과, 전기·전자공학분야의 웹 정보원이 가장 우수한 것으로 나타났다. 그리고 평가 기준간의 상관관계를 분석한 결과, 정보 콘텐츠와 기능성은 음의 관계를 가진 반면에 기능성과 디자인은 비교적 높은 상관관계가 있는 것으로 나타났다.

The purpose of this study is to propose the criteria for evaluating web information resources. This study also attempts to get a sense of the overall quality of web information resources and to identify the relationship among the criteria, particularly those on the science and technology. Three evaluation categories are proposed; information content, functionality or workability, and design. Core features of information content includes authority, relevancy, currency; functionality includes navigation, user support, technical requirements; layout and design includes visual appearance. Based on the proposed criteria, the 50 sample web resources selected from 5 different field were evaluated. The results showed that the web information resources on the Electrical and Electronic Engineering field was excellent. The Pearson's correlation coefficient between evaluation criteria showed that information content and functionality had a negative relationship, on the other hand, functionality and design had a moderate correlation.

This study is to review current state of web-based simulations for science learning about magnets and magnetic field, and evaluate the appropriateness of simulations in terms of contents, strategies and design. We designed a set of criteria for evaluating science simulations and applied it to 14 simulations about magnets and magnetic field. For the evaluation, eight elementary teachers participated and they described specific characteristics of each simulation according to the criteria. Based on the evaluation, we divided the simulations into two groups, excellent vs. normal groups. We analyzed strengths from the simulations in excellent group and weaknesses from the simulations in normal group according to the contents, learning strategies, screen format, and technical features. Implications for ways of improvement in developing web-based science simulations effective to science teaching and learning about magnets and magnetic field were discussed.
