  • This study describes an approach for comparative bibliometric analysis of scientific publications related to (i) individual or several departments comprising a university, and (ii) broader integrated subject areas using multiple disciplinary schemes. It uses a custom dataset of scientific publications (ca. 15,000 articles and reviews, published during 2009-2013, and recorded in the Web of Science Core Collections) with author affiliations to the research departments, dedicated to science, technology, engineering, mathematics, and medicine (STEMM), of a comprehensive university. The dataset was subjected, at first, to the department level and discipline level analyses using the newly available KAKEN-L3 classification (based on MEXT/JSPS Grants-in-Aid system), hierarchical clustering, correspondence analysis to decipher the major departmental and disciplinary clusters, and visualization of the department-discipline relationships using two-dimensional stacked bar diagrams. The next step involved the creation of subsets covering integrated subject areas and a comparative analysis of departmental contributions to a specific area (medical, health and life science) using several disciplinary schemes: Essential Science Indicators (ESI) 22 research fields, SCOPUS 27 subject areas, OECD Frascati 38 subordinate research fields, and KAKEN-L3 66 subject categories. To illustrate the effective use of the science mapping techniques, the same subset for medical, health and life science area was subjected to network analyses for co-occurrences of keywords, bibliographic coupling of the publication sources, and co-citation of sources in the reference lists. The science mapping approach demonstrates the ways to extract information on the prolific research themes, the most frequently used journals for publishing research findings, and the knowledge base underlying the research activities covered by the publications concerned.

  • The purpose of this study is to examine the unique characteristics of the Korean academic system with regard to brain circulation, with a specific emphasis on the influence of overseas-trained academics on research activities within the Korean academic system. We have analyzed the statistical data on individual characteristics and performances of 48,499 Korean academics in science and engineering. We have examined the results at both the system and individual levels within the broader context of the macro characteristics of the Korean academic system. Our analysis reveals that the total number of domestically-trained academics exceeds the number of overseas-trained academics. However, in terms of research funding, overseas-trained academics tend to receive more funding than domestically-trained academics. Furthermore, after controlling other factors such as funding, personal attributes, and environmental factors, our analysis demonstrates that overseas training has a significant and favorable impact on the publication of internationally renowned journals. As such, the presence of overseas returnees has been essential for the effective functioning of the Korean academic system in the global research network and for conducting high-quality academic research. Therefore, the advantages of dependence on scientific core countries such as the US for overseas training have persisted. Nevertheless, upon scrutinizing the group of recently appointed 5,806 academics exclusively, we have discovered that junior academics who received their education domestically exhibit sufficient academic proficiency compared to their colleagues educated overseas. This observation highlights the potential for the Korean academic system to evolve into a self-sustaining system.

  • This study aimed to investigate primary students' science-related attitudes through the literature review. Ninety-four papers published in domestic science education journals, since 1990, were collected and were followed by content analysis. In this study, science-related attitude was conceptualized as attitude toward science, scientist, science-related occupations, and school science, which is composed of cognitive, affective and behavioral domains. Based on the conceptualization, the instruments used for measuring students' attitudes were analyzed. The analysis of definition of science-related attitude in the articles showed different foci on cognitive, affective and behavioral domains. To suggest the effective instruction for enhancing students' science-related attitudes, this study identified students' attitude with gender, grade, residence and achievement level. The result showed that male, urban, higher-grade and better performed students had more positive attitude than female, rural, lower-grade and less performed students. As for the factors in science-related attitude, I categorized the factors into personal, environmental and pedagogical aspects, and found that psychological elements in all domains were most influential to students' change of science-related attitudes. It is interesting to note that students showed dichotomous views about experiment and that task-oriented instruction failed to enhance students' attitude. Based on the research findings, this study suggests effective instruction for improving students' attitudes and future research for science education.

  • In this paper, we propose a topic network analysis approach which integrates topic modeling and social network analysis. We collected 2,039 scientific papers from five top journals in the field of data mining published from 1996 to 2015, and analyzed them with the proposed approach. To identify topic trends, time-series analysis of topic network is performed based on 4 intervals. Our experimental results show centralization of the topic network has the highest score from 1996 to 2000, and decreases for next 5 years and increases again. For last 5 years, centralization of the degree centrality increases, while centralization of the betweenness centrality and closeness centrality decreases again. Also, clustering is identified as the most interrelated topic among other topics. Topics with the highest degree centrality evolves clustering, web applications, clustering and dimensionality reduction according to time. Our approach extracts the interrelationships of topics, which cannot be detected with conventional topic modeling approaches, and provides topical trends of data mining research fields.

  • Objective : The aim of this study is to review the historical development and current situation of Mongolian traditional medicine. Method : Systematic literature review for books, journals, governments statistics, reports on mongolian traditional medicine was carried out. Results : The theory of Mongolian traditional medicine is influenced by the philosophy and medical theories of the ancient orient such as India, Tibet and China-theories of hot and cold, principle of yin and yang and five elements. There are very unique treatments like brain tram concussion, fermented horse milk treatment as well as moxibustion, acupuncture, and blood letting. It appears that they are very closed to nomadic life. Training program of each institutes need to be standardized. Mongolian traditional medicine had been almost destroyed by the influence of communist idea from 1930s until the end of the 1980s. Since 1990, Mongolian government put much emphasis on the development of traditional medicine. And now about 3.7% of total beds is traditional medicine one and that there are six TM schools and the total number of traditional medicine in 2012 is 1696. However, there are still the lack of manpower, facilities, standardized training program and scientific research for traditional medicine. Conclusion : Mongolian traditional medicine has been developed over centuries in response to Mongolia's unique geographical and climate conditions and the lifestyles of its people and that made contribution to the health of mongolian people. However, it needs to be strengthened because there are poor infrastructure and training program.

  • Even the pharmacotherapy is more effective than placebo for the treatment of depression, the outcome of pharmacoltherapy remains unsatisfactory for many patients. Apart from side effects, there are two major limitations of antidepressant therapy. One is the delayed onset of improvement and another is partial response. In order to address these clinical dilemmas, many psychiatrists more commonly employ add-on therapy. In past, the practice of using multiple drugs to enhance treatment response was called polypharamcy, and was disparaged as poor clinical practice. However, with improved understanding of how drugs affects the central nervous system and increased communication in journals and on computer networks about the relative merits of specific combinations, the scientific basis for the combining drugs is being defined. Indeed, the use of multiple medications as a stratege to enhance response has become both acceptable and widespread now a days. It is now referred to more positively as add-on therapy, co-medication, combination therapy, or drug augmentation. Thus, as the methods of practical strategies for treatment of depression, switching classes antidepressant drugs, combination therapy, augmentation strategies and brief treatment algorithm will be presented with items of considerations. However, when combination of drugs being tried, knowledges about the action of mechanism, pharamcokinetics, and pharmacodynamics are essential to cope with the possible adversive reactions and to get the appropriate responses for the treatment of depressive symptoms.

  • Background: Shammah is a traditional form of chewing tobacco [smokeless tobacco, (ST)] that is commonly used in the Middle East especially in Saudi Arabia (KSA), Yemen and Sudan. The Substance Abuse Research Centre (SARC) at Jazan University noted that no adequate research and information on the prevalence of shammah use in the province of Jazan, and KSA as well, has been provided in the scientific literature. Materials and Methods: An intensive systematic review of online databases was performed, including AMED (The Allied and Complementary Medicine Database), Biological Abstracts, Cochrane Collection Plus, Dentistry and Oral Sciences Source, E-Journals Database, EBSCO Discovery Service, MEDLINE, PEMSoft, PEP Archive, PsycARTICLES, scopus, Sciencedirect and Google Scholar. Results: Shammah is a mixture of powdered tobacco, lime, ash, black pepper, oils and flavorings. ST in KSA is placed in the buccal or lower labial vestibule of the mouth. The user (or dipper) spits out insoluble debris. The importation of ST products is prohibited in KSA. Accessible information on legislative action to control the use of ST in KSA appeared in 1990. The actual percentage use may be higher, than reported since shammah is illegal in KSA and there may be some reluctance to admit to its use. Conclusions: This review paper is an initial step in a funded research project by SARC to understand the pattern of use of shammah and provide adequate epidemiological data. One goal of this review is to generate further data for public health education.

  • Basic summary of the medical administration : Due to Qing dynasty being the last of the dynastic era, it revealed overall extreme political traits in politics, economy, phenomenon, and cultural aspects. Few emperors of the early Qing dynasty adopted appeasement policy that mitigated ironies to a certain extent and showed growth in various business related fields. Even the medical administration had freshness during that period. United medical administrative system was generally formed, chicken pox was effectively prevented, shamanistic treatment was banned, medical journals were complied by the government, medical relief was more intensely done. However, actions on restoring Ming dynasty and against Qing dynasty as well as the reform power grew against Qing government threatening it. The drastically grown forces from the western region damaged Qing dynasty that the governors had to adopt despotic measures in politics, economy and culture. Social chaos began to arise, economy stagnated and weakened that the medical field also dwindled to the point where it could not be restored to the original point. The era of Qing dynasty was the period that had scientific culture at its fast growing pace, but for Chinese medicine, by contrary, due to autocracy and other factors, was faced with barriers in the medical development.
