Digital Science's Dimensions is envisaged as a next-generation research and discovery platform for more efficient access to cross-referenced scholarly publications, grants, patents, and clinical trials. As a new addition to the growing open citation resources, it offers opportunities that may benefit a wide variety of stakeholders of scientific publications, from researchers and policy makers to the general public. In this article, we explore and demonstrate some of the practical potentials in terms of cascading citation expansions. Given a set of publications, the cascading citation expansion process can be iteratively applied to a set of articles so as to extend the coverage to more and more relevant articles through citation links. Although the conceptual origin can be traced back to Garfield's citation indexing, it has been largely limited, until recently, to the few who have unrestricted access to a citation database that is large enough to sustain such iterative expansions. Building on the open application program interface of Dimensions, we integrate cascading citation expansion functions in CiteSpace and demonstrate how one may benefit from these new capabilities. In conclusion, cascading citation expansion has the potential to improve our understanding of the structure and dynamics of scientific knowledge.

Objectives : The aim of this study was to develop search filters able to retrieve the South Korean scientific output and relating the fields of public health, preventive medicine, and physical education, activity, fitness, exercise and sport in MEDLINE between 2000 and 2007. Methods : The search filters were constructed and applied in MEDLINE accessed through PubMed according to the affiliation and subject. The language and place of publication were identified and the evaluation of the geographical filter performance was done. Results : The search format was successfully elaborated and applied, and the articles originated, published in Korea and/or abroad focusing on the fields of public health, preventive medicine, physical education, activity, fitness, exercise and sport, added to MEDLINE between 2000 and 2007 were retrieved. Publications in six languages originated in South Korea were detected. Conclusions : A geographic search filter determined the South Korean research output, and combined with additional filters focused on specific areas. The dynamics of the scientific output followed an increased evolution in all categories. Articles were written mainly in English/Korean. Further research is recommended on developing search strategies in order to retrieve precise and reliable information.

While public interests in the metaverse are growing recently in the Korean media and research, its understanding has not been fully established yet. In this study, we aimed to probe whether the rapid growth in media attention about the metaverse has increased its usage as a buzzword accompanied by an absence of scientific context. We analyzed publications and online news containing "metaverse" from 2020 to 2022. The data analysis methods are 1) time series frequency, 2) keyword network, 3) natural language model. The findings indicate the perception gap about metaverse between research and news articles broadened as its popularity has grown. Research about metaverse gradually expanded its connections with related topics-virtual and augmented realities-focusing on social changes in a remote environment. However, media reporting frequently used "metaverse" as a buzzword rather than explaining its scientific background, stimulating the proliferation of related topics and the dispersion of news content. This study further discusses the need for a media strategy to improve public conception of the long-term development of the metaverse.

This short review article presents a current overview of existing publications and scientific results regarding liquid (ear) acupuncture. The injection of liquids into defined acupuncture points of the ear is not a method commonly used in the Western world. The term liquid acupuncture has different definitions, which makes understanding each definition and differentiating one from the other difficult. General terms like pharmacopuncture, homeosiniatry, and liquid acupuncture, which all describe the method of injecting different kinds of drugs into a defined body acupuncture point, are used. This article presents the history of liquid acupuncture, as well as the current scientific state of the art, from the point of view of two European researchers. Some articles are discussed and a few practical examples are presented.

The object of this study is to investigate and analyze the quantity and quality of informations on health, food and nutrition reported by newspapers. Six different major domestic daily newspapers(Hankook Ilbo, Donga IIbo, Chosun IIbo, Kyunghyang Shinmun, Hankyoreh Shinmun, JoongAng Ilbo), were monitored from 1st of May to 31st of Oct. 2002.. The results of monitoring in the newspapers were summarized as follows; 1. The total percentage of the articles on health and food nutrition was 2.7% and the percentage of the advertisements on health, food and nutrition was 17.5% of total area of the newspaper. The ratio of the number of food and nutrition topic on the total number of health and food nutrition topic was 35.8% for the articles, was 62.9% for the advertisements. Among advertisements on food and nutrition, the percentage of advertisements on healthy foods was the highest (3,481 or 55.0%). 2. Contents of 340 articles(26.1%) were reported as suitable informations. Contents of 259 articles(19.9%) were reported as inaccurate informations on health, food and nutrition. In the analysis of advertisements, the number of advertisements without sufficient reliable sources was 2,488 cases(23.0%), and with exaggerated contents was 2,268 cases(21.0%). The articles and advertisements should be backed by scientific research or reliable sources and also the opinions of people with expertise in order to report accurate informations to the general public. In order to achieve these results, there should be continuing monitoring activity for the newspapers.

This study was intended to help children to cultivate and develop a sound attitude toward food consumption and eating habits through the analysis of food and nutritional information in news articles and advertisements in three major daily children's newspapers in Korea: The Chosen Children's Daily Newspaper, The Hankook Children's Daily Newspaper, and The Donga Children's Daily Newspaper. The monitoring period was for twelve months, January to December 2003. Two hundred seventy-nine articles and three hundred thirty-five advertisements were analyzed. The results were as follows. 'Cooking and health' were the most frequent subject in food and nutrition articles. The articles' contents are evaluated positively in morality and explanation; but negatively in fairness, specialization, and objectiveness. The articles were insufficient in the explanation of professional terms, scientific bases, and practical measures for real life. It therefore seems that they were difficult for children to understand well. The most frequent themes in the advertisements were 'processed fats and sugars' such as chocolate, candies, and cookies. Frequently, they were exaggerated and accompanied by phrases promoting consumption. They did not provide sufficient well-grounded information, and focused too much on events or gifts to instigate consumer sentiment. In conclusion, the most serious problem was that most food and nutrition information in these children's newspapers was lacking in specialization. More specialized and objective information should be provided in order to enhance the educational value of children's newspapers and their utilization in school education programs. Continuous monitoring should be carried out to discover those news articles and advertisements that contain correct food and nutrition information.

미국에서 기초연구는 기술발전 또는 경제성장에 크게 기여한 것으로 여겨진다. 특히 기초과학의 상당 부분을 담당하는 대학은 과학지식 연구, 교육, 기술이전 등의 활동을 통해 경제성장에 실질적으로 기여하고 있는 것으로 평가받고 있다. 그러나 과학이 기술적 성과에 어떤 영향을 얼마나 끼치는가는 아직 명확하지 않으며, 여러 학자들은 과학과 기술의 상호작용은 생각보다 매우 복잡하다고 말한다. 이 연구는 이러한 맥락에서 과학지식과 기술의 상호작용(또는 과학기술연계) 특성을 분석하였다. 분석은 미국을 대상으로 하였다. 미국의 R&D지출 규모, 과학논문수, 특허에 인용된 과학논문 등을 활용하였다. 분석결과 미국특허는 대학의 과학논문을 가장 많이 인용하였다. 그러나 전체 과학논문수를 고려한 상대적 인용 강도는 산업부문이 더 높았다. 즉, 과학과 기술의 연계는 대학에서 가장 많이 이루어지지만 상대적인 크기를 고려하면 산업부문의 과학지식이 더 활발하게 기술로 이어지고 있다고 볼 수 있다. 한편 과학분야별 분석에서는 화학, 물리, 생물학 분야에서 과학기술연계가 가장 활발하게 이루어지고 있었다. 특히 컴퓨터과학, 농경학, 공학 분야는 최근 연계강도가 크게 증가하였다. 결과적으로 본 연구는 과학지식에 대한 정부지원정책 또는 연구개발평가 등에 도움을 줄 것으로 기대된다. 대학은 가장 많은 과학기술연계가 이루어지는 공간이며, 이 점에서 대학 기초과학에 대한 정부지원은 여전히 중요하다. 산업부문 과학지식은 다른 연구주체보다 상대적으로 기술연계강도가 높았으며, 이는 산업부문의 과학지식생산 또한 장려할 필요가 있다는 것을 의미한다. 과학분야별로는 각 과학분야의 R&D유형을 4가지로 분류하여 연구결과의 정책적 활용도를 높이고자 하였다.

The objective of this study is to analyze the research articles on clinical social work practice effectiveness to build a scientific and scholaristic image of clinical social work practice. The data for analysis were the articles published in 13 professional journals including Korean J. of Social Welfare in the period of 1979 to 1999. The appearance rate of effectiveness studies was 1.28% with only 18 articles. Experimental studies consisted only 4 out of 18, and there were only 10 Quasi-experimental studies. Statistical errors were observed in most studies, so it is too early to call that the clinical social work practice is either effective or not effective. In order to see the comprehensive trends of the clinical social work practice, other clinical papers were also examined. The appearance rate was also as low as 8.75% (effectiveness studies included). While 18 articles were about the therapy model, other clinical papers were about generic practice models. However, those newly developed generic practice models had not yet been widely used nor tested for effectiveness. Thus, the followings were suggested: active research activities with solid methodology, team work with the field, theory and method development, education and re-education, and collaborative team work with other related fields. It was also pointed that the cross analysis of research papers by the publishing period, authors major and other background variables would be useful.
