Objectives: This scientometric and bibliometric analysis explored scientific publications related to hydraulic calcium silicate-based (HCSB) sealers used in endodontology, aiming to describe basic bibliometric indicators and analyze current research trends. Materials and Methods: A comprehensive search was conducted in Web of Science and Scopus using specific HCSB sealer and general endodontic-related terms. Basic research parameters were collected, including publication year, authorship, countries, institutions, journals, level of evidence, study design and topic of interest, title terms, author keywords, citation counts, and density. Results: In total, 498 articles published in 136 journals were retrieved for the period 2008-2023. Brazil was the leading country, and the universities of Bologna in Italy and Sao Paolo in Brazil were represented equally as leading institutions. The most frequently occurring keywords were "calcium silicate," "root canal sealer MTA-Fillapex," and "biocompatibility," while title terms such as "calcium," "sealers," "root," "canal," "silicate based," and "endodontic" occurred most often. According to the thematic map analysis, "solubility" appeared as a basic theme of concentrated research interest, and "single-cone technique" was identified as an emerging, inadequately developed theme. The co-occurrence analysis revealed 4 major clusters centered on sealers' biological and physicochemical properties, obturation techniques, retreatability, and adhesion. Conclusions: This analysis presents bibliographic features and outlines changing trends in HCSB sealer research. The research output is dominated by basic science articles scrutinizing the biological and specific physicochemical properties of commonly used HCSB sealers. Future research needs to be guided by studies with a high level of evidence that utilize innovative, sophisticated technologies.

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.

연구개발에 따른 성과물은 다양한 형태가 있지만 대부분의 경우 일차적으로 논문의 형태로 발표된다. 따라서 논문에 대한 분석은 연구 성과 평가의 가장 기본적인 수단이 된다. 문제는 논문으로 나타난 연구성과를 얼마나 객관적으로 측정할 수 있는가이다. 학문분야의 특징에 따라 논문 수는 물론 인용횟수 등이 다르게 나타나기 때문에 발표된 논문의 수준이 어느 정도인지를 객관적으로 평가하는 일은 성과분석의 가장 중요한 첫걸음이다. 이 논문에서는 SCI 논문을 대상으로 증거기반 접근을 실시함으로써 주요국에서 생산되는 논문들이 세계 속에서 차지하는 질적 위상을 분석하고자 하였다. 이러한 분석을 위해 여러 연구진들이 수행해 왔던 SCI 논문 질적 계량지표를 살펴보았으며, 이들 지표의 한계점을 보완함으로써 연구 분야별 비교, 국가별 비교, 세계 수준과 비교가 가능한 신규 계량지표, 상대적 순위보정영향력지수(Relatively Rank-Normalized Impact Factor, $R^2nIF$)를 개발하였다. 본 연구를 통해 흥미를 끄는 두 가지 결과를 얻을 수 있었다. 우선 우리의 예상을 벗어나 태국과 이집트, 그리고 뉴질랜드가 각각 지구과학, 수학, 약리학에서 가장 우수한 논문을 생산하고 있는 국가로 분석되었다는 점이다. 둘째는 인구 500만 이하의 강소국인 유럽의 스위스, 네덜란드, 덴마크, 아시아의 싱가포르, 그리고, 중동의 이스라엘이 최고 수준의 논문 생산국이라는 점이다. 특히, 스위스는 분석 대상 21개 분야 중 컴퓨터과학, 면역학 등 무려 4개 분야에서 가장 우수한 논문을 생산하는 국가로 랭크되었고, 네덜란드는 화학과 임상의학 등 3개 분야에서 최고 수준의 논문을 생산하는 것으로 나타났다. 이처럼 전 세계에서 높은 국가 경쟁력을 자랑하고 있는 강소국들이 과학분야에서도 높은 수준의 논문을 생산하고 있음을 확인할 수 있었다. 본 연구를 통해 개발한 Relatively Rank-Normalized Impact Factor를 SCI논문 성과분석에 적용해 본 결과, 향후 이 신규 질적지표는 피인용횟수(Citation) 정보 수집이 불가능한 대부분의 성과분석 및 성과평가에 적절하게 활용될 수 있을 것으로 기대된다.

Information technologies in higher education are the basis for solving the tasks set by monitoring the quality of higher education. The directions of aplying information technologies which are used the most nowadays have been listed. The issues that should be addressed by monitoring the quality of higher education with the use of information technology have been listed. The functional basis for building a monitoring system is the cyclical stages: Observation; Orientation; Decision; Action. The monitoring system's considered cyclicity ensures that the concept of independent functioning of the monitoring system's subsystems is implemented.. It also ensures real-time task execution and information availability for all levels of the system's hierarchy of vertical and horizontal links, with the ability to restrict access. The educational branch uses information and computer technologies to monitor research results, which are realized in: scientific, reference, and educational output; electronic resources; state standards of education; analytical materials; materials for state reports; expert inferences on current issues of education and science; normative legal documents; state and sectoral programs; conference recommendations; informational, bibliographic, abstract, review publications; digests. The quality of Ukrainian scientists' scientific work is measured using a variety of bibliographic markers. The most common is the citation index. In order to carry out high-quality systematization of information and computer monitoring technologies, the classification has been carried out on the basis of certain features: (processual support for implementation by publishing, distributing and using the results of research work). The advantages and disadvantages of using web-based resources and services as information technology tools have been discussed. A set of indicators disclosed in the article evaluates the effectiveness of any means or method of observation and control over the object of monitoring. The use of information technology for monitoring and evaluating higher education is feasible and widespread in Ukrainian education, and it encourages the adoption of e-learning. The functional elements that stand out in the information-analytical monitoring system have been disclosed.
