  • Mendeley의 독자 정보는 학계 밖에서 학문의 결과물이 어떻게 소비되고 있는지 다각도로 파악하여 피인용도로는 해석할 수 없었던 미지의 세계를 예측하는데 활용될 수 있다. 본 연구는 Mendeley의 co-readership 데이터를 활용해 한국 관련 논문의 독자 국가 네트워크 분석을 수행하여 공통의 학문적 관심사를 공유하는 국가 군집을 이해하고 이들 국가가 네트워크 상에서 어떠한 영향력을 가지는지 확인하였다. 그 결과 전 분야에서 미국을 비롯한 선진국은 대체로 높은 전역중심성을 보여 한국 관련 연구에 대한 전반적인 협력과 잠재적 교류 가능성을 가지는 것으로 나타났으며, 일부 개발도상국은 높은 지역중심성을 보여 상호간 공통의 학문적 관심사로 연계되어 있는 것으로 확인되었다. 한편 의학과 사회과학 분야는 OECD 국가와 개발도상국이 분리된 독자층을 이루었으며, 공학 분야는 신흥경제개발국이 대규모 독자 군집으로 형성되는 특징을 보였다. 또한 공학은 네트워크 밀도가 상대적으로 높게 나타나 국가간 학문적 교류와 지식의 확산, 협력의 가능성이 높은 것으로 분석되었다.

  • Objectives: To compare the effectiveness and safety of East Asian traditional medicine treatments (EATMT) versus conventional management in patients following heart valve replacement surgery. Methods: We searched several databases, including the Korean Studies Information Service System, PubMed, China National Knowledge Infrastructure, and Citation Information by NII. The search range included randomized controlled trials from each first issue until June 27, 2021. Two review authors independently extracted the data. We assessed the risk of systematic errors by evaluating risk domains using the "Risk of bias" tool. Results: We included 5 trials in the review. In the EATMT, the investigators reported significant improvements in reshaping of the heart structure: left ventricular end diastolic diameter (MD -4.43, 95% CI -6.06 to -2.79; 130 participants; 2 studies; high evidence). Comparisons with usual care revealed a significant decrease in gastrointestinal complications rate (OR 0.30, 95% CI 0.20 to 0.47; 503 participants; 2 studies; high evidence). We assessed 4 studies as having a low risk of bias and 1 study as having a high risk of bias. Conclusion: This systematic review suggests that East Asian traditional medicine interventions may be effective in preventing and alleviating complications, but we found evidence of important trade-offs between known benefits and known adverse effects in cardiac dysfunction and inflammation following heart valve replacement. Consequently, additional high-quality studies should be conducted.

  • Objectives: This study reviewed randomized controlled trials (RCTs) investigating the efficacy of herbal medicine on sleep disorders associated with Parkinson's disease and suggests a better research process. Methods: We searched for RCTs for herbal medicine treatments for sleep disorders related to Parkinson's disease on July 31, 2023 using eight databases (PubMed, Embase, the Cochrane library, China National Knowledge Infrastructure [CNKI], the Research Information Service System [RISS], Science ON, the Oriental Medicine Advanced Searching Integrated System [OASIS], and the Korea Citation Index [KCI]). Cochrane's risk of bias tool was used to assess the quality of the RCTs. Results: A total of 16 RCTs met all the inclusion criteria, and in most reports, the treatment group showed a significant improvement in sleep disorders compared to the control group. Total effective rate (TER), Pittsburgh Sleep Quality Index (PSQI), Unified Parkinson's Disease Rating Scale (UPDRS), TCM Symptom Score (TSS), Parkinson's Disease Sleep Scale (PDSS), etc., were used as evaluation indicators. Conclusion: Herbal medicine is a potential treatment for sleep disorders associated with Parkinson's disease. However, the selected RCTs were of poor quality, and it is necessary to perform more systematic studies.

  • Objectives : This study is to investigate the current National Health Insurance Database cohort studies related to complications of Parkinson's Disease (PD) and suggest the design of Korean medical epidemiological studies of PD. Methods : Nationwide longitudinal studies of PD patients in South Korea were collected through Pubmed and the Korea Citation Index (KCI). We selected cohort studies that used the National Health Insurance Database in Korea and targeted Parkinson's disease patients. Studies published before February 2024 were categorized according to study designs. We examined variables and covariates, enroll dates and matching methods. Results : Of a total of 536 studies, 18 studies met the inclusion criteria. All studies used the National Health Insurance (NHI) Research Database and among them, 5 used sample data and one senior database. Studies can be classified into two types. 11 cohort studies were comparing PD patients and non-PD patients. Another type was 4 PD patients cohort studies. Most studies used two diagnostic codes (G20 and V124) for inclusion criteria. Enroll periods were from 2002 to 2017, and follow-up periods were from 7 to 14 years. 16 studies considered age and sex as covariates. 15 studies used the propensity score matching method to increase the level of causality. There was only one study related to the Korean medical treatment. Conclusion : In future cohort studies on Korean medical treatment, more attempts should be made to reveal the effect of the treatments on PD patients by defining inclusion criteria for patient groups, covariates, exposure variables, and assessment indicators more operatively.

  • 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.

  • As an official journal of the Asian-Australasian Association of Animal Production Societies (AAAP), the Asian-Australasian Journal of Animal Sciences (AJAS) was born in February 1987 and the first issue (Volume 1, Number 1) was published in March 1988 under the Editorship of Professor In K. Han (Korea). By the end of 2001, a total of 84 issues in 14 volumes and 1,761 papers in 11,462 pages had been published. In addition to these 14 volumes, a special issue entitled "Recent Advances in Animal Nutrition" (April, 2000) and 3 supplements entitled "Proceedings of the 9th AAAP Animal Science Congress" (July, 2000) were also published. Publication frequency has steadily increased from 4 issues in 1988, to 6 issues in 1997 and to 12 issues in 2000. The total number of pages per volume and the number of original or review papers published also increased. Some significant milestones in the history of the AJAS include that (1) it became a Science Citation Index (SCI) journal in 1997, (2) the impact factor of the journal improved from 0.257 in 1999 to 0.446 in 2000, (3) it became a monthly journal (12 issues per volume) in 2000, (4) it adopted an English editing system in 1999, and (5) it has been covered in "Current Contents/Agriculture, Biology and Environmental Science since 2000. The AJAS is subscribed by 842 individuals or institutions. Annual subscription fees of US$ 50 (Category B) or US$ 70 (Category A) for individuals and US$ 70 (Category B) or US$ 120 (Category A) for institutions are much less than the actual production costs of US$ 130. A list of the 1,761 papers published in AJAS, listed according to subject area, may be found in the AJAS homepage (http://www.ajas.snu.ac.kr) and a very well prepared "Editorial Policy with Guide for Authors" is available in the Appendix of this paper. With regard to the submission status of manuscripts from AAAP member countries, India (235), Korea (235) and Japan (198) have submitted the most manuscripts. On the other hand, Mongolia, Nepal, and Papua New Guinea have never submitted any articles. The average time required from submission of a manuscript to printing in the AJAS has been reduced from 11 months in 1997-2000 to 7.8 months in 2001. The average rejection rate of manuscripts was 35.3%, a percentage slightly higher than most leading animal science journals. The total number of scientific papers published in the AJAS by AAAP member countries during a 14-year period (1988-2001) was 1,333 papers (75.7%) and that by non- AAAP member countries was 428 papers (24.3%). Japanese animal scientists have published the largest number of papers (397), followed by Korea (275), India (160), Bangladesh (111), Pakistan (85), Australia (71), Malaysia (59), China (53), Thailand (53), and Indonesia (34). It is regrettable that the Philippines (15), Vietnam (10), New Zealand (8), Nepal (2), Mongolia (0) and Papua New Guinea (0) have not actively participated in publishing papers in the AJAS. It is also interesting to note that the top 5 countries (Bangladesh, India, Japan, Korea and Pakistan) have published 1,028 papers in total indicating 77% of the total papers being published by AAAP animal scientists from Vol. 1 to 14 of the AJAS. The largest number of papers were published in the ruminant nutrition section (591 papers-44.3%), followed by the non-ruminant nutrition section (251 papers-18.8%), the animal reproduction section (153 papers-11.5%) and the animal breeding section (115 papers-8.6%). The largest portion of AJAS manuscripts was reviewed by Korean editors (44.3%), followed by Japanese editors (18.1%), Australian editors (6.0%) and Chinese editors (5.6%). Editors from the rest of the AAAP member countries have reviewed slightly less than 5% of the total AJAS manuscripts. It was regrettably noticed that editorial members representing Nepal (66.7%), Mongolia (50.0%), India (35.7%), Pakistan (25.0%), Papua New Guinea (25.0%), Malaysia (22.8%) and New Zealand (21.5%) have failed to return many of the manuscripts requested to be reviewed by the Editor-in-Chief. Financial records show that Korea has contributed the largest portion of production costs (68.5%), followed by Japan (17.3%), China (8.3%), and Australia (3.5%). It was found that 6 AAAP member countries have contributed less than 1% of the total production costs (Bangladesh, India, Indonesia, Malaysia, Papua New Guinea and Thailand), and another 6 AAAP member countries (Mongolia, Nepal and Pakistan, Philippine and Vietnam) have never provided any financial contribution in the form of subscriptions, page charges or reprints. It should be pointed out that most AAAP member countries have published more papers than their financial input with the exception of Korea and China. For example, Japan has published 29.8% of the total papers published in AJAS by AAAP member countries. However, Japan has contributed only 17.3% of total income. Similar trends could also be found in the case of Australia, Bangladesh, India, Indonesia, Malaysia and Thailand. A total of 12 Asian young animal scientists (under 40 years of age) have been awarded the AJAS-Purina Outstanding Research Award which was initiated in 1990 with a donation of US$ 2,000-3,000 by Mr. K. Y. Kim, President of Agribrands Purina Korea Inc. In order to improve the impact factor (citation frequency) and the financial structure of the AJAS, (1) submission of more manuscripts of good quality should be encouraged, (2) subscription rate of all AAAP member countries, especially Category B member countries should be dramatically increased, (3) a page charge policy and reprint ordering system should be applied to all AAAP member countries, and (4) all AAAP countries, especially Category A member countries should share more of the financial burden (advertisement revenue or support from public or private sector).

  • 현재 국내외 대학도서관의 전자학술정보 입수는 일명 빅딜로 불리는 수백, 수천 종의 전자학술지 묶음을 다년간, 고정된 인상율로 계약하는 구독방식이 주류를 이루고 있다. 1990년대 중반에 시작된 이러한 구독방식은 대학도서관과 이용자에게 많은 장점을 제공했다. 하지만 이들 패키지의 가격이 지속적으로 상승함에 따라 이러한 방식의 지속가능성에 대한 의문이 제기되고 있다. 현재까지 pay-per-view 방식을 제외하면 구독기반 모형의 구체적인 대안은 제시되지 않고 있으며 향후 도서관 예산문제가 심각한 뇌관으로 남아있다. 2000년대 초반 시작된 오픈액세스 운동은 다양한 방법으로 학술지의 출판과 유통의 장벽을 제거하고 있다. 오픈액세스 출판 규모는 매년 두 자릿수로 증가하고 있고, 오픈액세스 학술지 논문은 Scopus와 Web of Science 인용데이터베이스에의 편입비율이 20%에 육박하는 등 양적, 질적인 성장을 보이고 있다. 2004년에 시작된 구글 학술검색은 현재 대다수 학술출판사의 학술지 논문에 대한 편리한 검색 및 접근 도구로 성장하고 있다. 비록 학술지 선택의 기준, 제한된 검색 기능, 독점화에 대한 우려 등이 있지만 구글 학술검색을 대학도서관 데이터베이스의 대안으로 진지하게 주목할 필요가 있다. 대학도서관의 예산 문제, 오픈액세스 출판의 활성화, 구글 학술검색과 같은 무료 도구의 성장은 구독기반 모형을 대체할 수 있는 파괴적인 변화로 인식되고 있으며 대학도서관 사서는 새로운 환경에 대한 구체적인 대응을 고민해야 한다.

  • 21세기에 들어서서 디지털 정보환경이 발빠르게 변화함에 따라 국내 정보학 연구 역시 많은 발전과 변화를 겪고 있는 것을 산학계 모두 인지하고 있지만 실제 2000년부터 현재까지 어느 정도로 변화되었는지를 분석한 논문은 많지 않다. 이에 따라 본 연구는 2000년에서부터 2011기간동안 연구재단에 등재된 문헌정보학 관련 학회지에 수록된 정보학분야 논문 1,007편의 논문을 대상으로 정보학분야의 연구동향을 분석하였다. 먼저 시간에 따른 연구주제의 변화를 살펴보기 위하여 논문 데이터를 주제 범주화 한 후, 각 주제 범주 내에서의 논문 및 주요 키워드의 성장률을 시계열적으로 분석하였다. 그리고 단어 동시출현 네트워크를 2000-2011년뿐 아니라 2000-2005년과 2006-2011년의 두 시기로 나누어 시각화하고 분석함으로써, 한국의 정보학 분야의 연구경향의 변화를 살펴보았다. 분석 결과, 지난 12년간의 한국의 정보학 연구는 정보시스템중심적 연구에서 이를 도서관에 적용하는 도서관응용적 연구로 나아가고 있는 것을 확인하였다. 특히 지식관리, 웹기반 시스템 평가, 정보검색 분야에서 두드러지게 변화가 나타났다. 다른 연구의 결과와 비교해 볼 때, 이 연구는 정보학 연구분야의 한국 로컬화의 변화를 찾아냈다는 점에서 의의가 있다고 할 수 있다.

  • Purpose: This study aims to examine the research output in the field of nursing at the global level during the last two decades, viz., for the period 1996-2015, with special reference to India. Some of the aspects examined include the research growth in nursing literature during the period of study, leading nursing research countries at the regional and global level, and citation analysis. Scope and Methodology: This study is global in nature, but emphasis has also been laid on India's research contribution in nursing at the global level. Aspects like regional contribution to the nursing research output have also been assessed. This study is purely based on secondary data retrieved from SCImago Journal and Country Rankings. The figures in the study are based on one particular database and are not exhaustive; hence they simply reflect a trend in nursing research at the global level. Findings: During the period 1996 through 2015, a total of 550,490 research articles were published across the world by 212 nation states at an average of 2,596 articles from each individual country. On average, during the period of study, the number of nursing research publications grew at the rate of 7.36% each year. North America has emerged as one of the leading nursing research continents of the world by publishing 218,614 research articles, constituting 39.71% of the global nursing research output. The U.S. and U.K. are the world's two leading nursing research countries, which contributed 193,819 and 61,730 research articles respectively, comprising a 35.21% and 11.21% share of global nursing research output. India and China, apart from being the two fastest growing nursing research countries, have the potential to meet the global human resource demand in the field of nursing, given the skilled and trained human resource both these countries possess in nursing. Social Implication: There is always a need to share working knowledge in some professions and nursing is one of them. There cannot be a better medium than linking practice with theory through the research medium. Metric studies in turn help to get a better idea about the amount of work done in any given field at the national and international level, thus identifying the need thereof to improve upon those areas where there is research lag.

  • Background: Fall-related injuries in older adults are a major health problem, and the risks and mechanisms of these injuries should be affected by race, culture, living environment, and/or economic status. Objects: Research articles have been systematically reviewed to understand fall-related injuries in older adults in South Korea. Methods: 128 published research papers have been found through the Korea Citation Index and the Korean Studies Information Service System, and reviewed in various perspectives, including incidents, fall death rates, medical costs, causes, injury sites and types, locations where falls occurred, prevention strategies, scholarly fields interested in fall injuries, and the role of physical therapy. Results: Fall-related injuries were found to be more common in women than in men, and the number of incidents increased with age, with the highest rate found in individuals over 85 years old. Risk of fall injury was associated with education level, comorbidities, and fear of falling. Common places where falls occurred included the bathroom, living room, stairs, and hallway. Common types of injury included bruises, fractures, and sprains in the lower extremities. Intervention strategies included exercise programs, education, and protective clothing. Scholarly fields interested in fall-related injuries in older adults included medicine, nursing, physical therapy, occupational therapy, physical education, pharmacology, oriental medicine, biomedical engineering, design, clothing, and textiles. Physical therapy intervention using proprioceptive neuromuscular facilitation has been used to improve one's balance. Conclusion: Any movement during the activities of daily living can lead to a fall. Physical therapists are highly educated to analyze human movements and should be involved in more research and practices to solve fall-related injuries in older adults.
