  • Objective: The purpose of this study is to explore trends in institutional evaluation research in early childhood education through keyword network analysis. This aims to understand trends in academic discourse on institutional evaluation and gain implications for follow-up research and related policy directions. Methods: A total of 6,629 keywords were extracted from 572 dissertations and journal articles published from January 2006 to October 2023 for the purpose of analyzing and visualizing the frequency and centrality of keywords, as well as the structural properties of keyword networks. The analysis and visualization were conducted using the TEXTOM, UCINET6, and NetDraw programs. Results: First, the number of institutional evaluation studies increased steadily from 2006 to 2010 and then decreased, with a higher frequency of studies on daycare centers compared to kindergartens. Second, the most frequently occurring keyword in the analysis was 'daycare center,' and the highest connection strength was found in the term 'daycare-center-evaluation.' Third, network analysis revealed that key terms for institutional evaluation research included 'evaluation certification,' 'recognition,' 'evaluation indicators,' 'teacher,' 'daycare center,' and 'kindergarten.' In the ego network analysis for each institution, 'parent' emerged as a highly ranked keyword. Conclusion/Implications: This study confirmed the perspectives of previous studies by revealing the structure of core concepts in early childhood education institution evaluation research, and provided implications for follow-up and direction of institution evaluation

  • Objectives: To circumvent the limitations of the current golden standard method, colony-forming unit (CFU) assay, for viability of Bacille Calmette-$Gu{\acute{e}}rin$ (BCG) vaccines, we developed a new method to rapidly and accurately determine the potency of BCG vaccines. Methods: Based on flow cytometry (FACS) and fluorescein diacetate (FDA) as the most appropriate fluorescent staining reagent, 17 lots of BCG vaccines for percutaneous administration and 5 lots of BCG vaccines for intradermal administration were analyzed in this study. The percentage of viable cells measured by flow cytometry along with the total number of organisms in BCG vaccines, as determined on a cell counter, was used to quantify the number of viable cells. Results: Pearson correlation coefficients of FACS and CFU assays for percutaneous and intradermal BCG vaccines were 0.6962 and 0.7428, respectively, indicating a high correlation. The coefficient of variation value of the FACS assay was less than 7%, which was 11 times lower than that of the CFU assay. Conclusion: This study contributes to the evaluation of new potency test method for FACS-based determination of viable cells in BCG vaccines. Accordingly, quality control of BCG vaccines can be significantly improved.

  • 본 연구에서는 전국의 국공립 및 사립, 전문대학의 교수들 2,618명을 대상으로 교수연구업적평가와 관련하여 교수들의 인식을 파악하고자 설문조사를 수행하였다. 설문조사는 두 가지 부분에 대한 인식을 파악하기 위한 조사로 하나는 현재 각 대학에서 진행되고 있는 교수연구업적평가에 대한 인식조사이며, 다른 하나는 정량 위주의 업적평가 방식의 대안으로 여겨지는 정성적 평가 지표의 도입에 대한 인식조사이다. 설문 결과, 교수 연구업적평가에서 정량 중심 평가는 여전히 대다수의 대학에서 크게 활용되며, 계열 또는 분야에 적합하지 않은 연구업적평가가 이루어지고 있으며, 평가 기간의 확대가 필요를 요구하고, 정량 위주의 업적평가 방식은 학술 커뮤니티에 부정적인 영향을 가져오며, 연구업적평가에 대한 개선의 필요하다는 인식을 가지고 있는 것을 확인할 수 있었다. 정성적 평가 지표의 도입과 관련하여 교수들은 연구업적평가에 정성적 평가가 필요하다는 인식을 하고 있으며, 정성적 평가 도입과 관련하여 부정적인 의견 또한 존재하는 것을 확인할 수 있었다.

  • Synthetic cannabinoids (CBs) such as the JWH series have caused social problems concerning their abuse liability. Because the JWH series produces euphoric and hallucinogenic effects, they have been distributed illegally under street names such as "Spice" and "Smoke". Many countries including Korea have started to schedule some of the JWH series compounds as controlled substances, but there are a number of JWH series chemicals that remain uncontrolled by law. In this study, three synthetic CBs with different binding affinities to the $CB_1$ receptor (JWH-073, 081, and 210) and ${\Delta}^9$-tetrahydrocannabinol (${\Delta}^9$-THC) were evaluated for their potential for psychological dependence. The conditioned place preference test (unbiased method) and self-administration test (fixed ratio of 1) using rodents were conducted. $K_i$ values of the three synthetic cannabinoids were calculated as supplementary data using a receptor binding assay and overexpressed $CB_1$ protein membranes to compare dependence potential with $CB_1$ receptor binding affinity. All mice administered JWH-073, 081, or 210 showed significantly increased time spent at unpreferred space in a dose-dependence manner in the conditioned place preference test. In contrast, all tested substances except ${\Delta}^9$-THC showed aversion phenomenon at high doses in the conditioned place preference test. The order of affinity to the $CB_1$ receptor in the receptor binding assay was JWH-210 > JWH-081 >> JWH-073, which was in agreement with the results from the conditioned place preference test. However, no change in self-administration was observed. These findings suggest the possibility to predict dependence potential of synthetic CBs through a receptor binding assay at the screening level.

  • 연구성과평가와 연구비 배분에 인용분석을 포함한 계량정보학적 분석방법이 많이 사용되고 있으며, 부적절한 적용 및 해석에 대한 우려와 지적 또한 계속되고 있다. 이에 따라 최근 연구성과평가 지침과 권고안이 학술 커뮤니티와 계량서지학적 연구집단에서 연이어 발표되고 있다. 따라서 이 연구에서는 2015년 발표된 라이덴 선언(Leiden Manifesto)을 중심으로 Thomson Reuters 백서, 프랑스 과학원 권고안, DORA 선언, IEEE 권고안을 비교하고 이를 통해 국내 연구성과평가 환경에의 제안 가능성을 살펴보고자 하였다. 비교분석 결과, 다수의 권고안은 연구의 목적과 연구 주제분야별 특성을 반영하고 다양한 지표를 활용한 다면적 평가를 통해 총체적인 평가를 지향하고 있는 것으로 나타났다. 이러한 결과는 국내 연구성과평가시스템 적용에서 고려해 볼 주요 권고안이라고 할 수 있으며, 추후 이에 대한 이해관계자들의 의견 수렴 등을 통하여 국내 연구성과시스템에의 적용가능성을 보다 심층적으로 살펴볼 필요가 있을 것이다.

  • The purpose of this study is to investigate the characteristics of the research paradigm and to explore the characteristics and limitations of the representative evaluation models belonging to each paradigm. The research paradigm is Positivism, Interpretivism, Critical Theory, and Postmodernism. The evaluation models that represent each paradigm include Objective-oriented evaluation model, Forth generation evaluation model, Empowerment evaluation model, Connoisseurship & Criticism model. The characteristics of each evaluation model reflects the characteristics of their own research paradigm.

  • 항공우주연구원에서는 정지궤도용 우주발사체에 적용 가능한 고성능 상단 엔진에 대한 선행기술 개발이 진행 중에 있다. 한국형발사체(KSLV)는 gas generator를 이용한 개방형 사이클 엔진이며, 저궤도 위성 발사를 위한 발사체로 향후 정지궤도위성 발사체를 위해서는 이보다 높은 비추력을 가진 고효율의 상단엔진이 필요하게 된다. 이러한 요구조건을 충족시키기 위해 다단 연소방식의 엔진이 필요하며, 본 논문에서는 당 연구원이 진행 중인 다단 연소 사이클 엔진 개발 진행 현황과 향후 계획을 기술하였다.
