In this study, journal selection processes of the Science Citation Index (SCI) and the SCOPUS are investigated aiming at making the Journal of the Korean Meteorological Society (JKMS) an SCI journal. In addition, some characteristic features of the SCI journals in the field of atmospheric sciences published in Asian countries are examined. Some domestic journals in the related disciplines that are recently listed in the SCI and SCOPUS are also analyzed in terms of strategic approaches. Results of this study may provide fundamental strategic information in pursuing the JKMS to be listed in the SCI in the near future.

As the important factors to improve research performance, the researchers' capacity and the input of resources like research funds have been pointed out. As joint researches are recently vitalized, however, the scientific knowledge is produced by forming continuous mutual relations through the structural characteristics between researchers. Since the support of research funds becomes a foothold to perform researches as multiple institutions cooperate with each other, it can be considered to have influence on research performance. In other words, it can be estimated that the support of research funds has influence on research performance by generating differences in the connecting structure of joint researches. In the results of analyzing the relation between network structure and research performance in accordance with the matter of supporting research funds, targeting the joint research theses in the culture technology(CT) area for five years from 2009 to 2013 in SCIE DB, when multiple research institutes are connected to each other, the number of thesis is increased. When the betweenness centrality is increased, the number of thesis is decreased. Also, the matter of supporting research funds has influence on network structure and research performance.

The aim of this research is to map the intellectual structure of the field of LED and optics during the period of 2000-2009. We utilize the scientometric tool of co-word analysis to reveal patterns and trends in the LED and optics field by measuring the association strengths of keywords (or IPCs). Data were collected from Science Citation Index Expanded (SCIE) and United Stated Patent and Trademark Office (USTPO) for the period of 2000-2009. Keywords were extracted from abstracts and further standardized using thesaurus. In order to trace the dynamic changes of the LED and optics field, the whole 10-year period was separated into two consecutive periods: 2000-2004 and 2005-2009. The results show that the LED and optics field has some established research themes and it also changes to embrace new themes.

The purpose of this paper is to analyze academic papers published by North Korean scientists, to uncover major areas of research in North Korean science and technology, and to uncover the intellectual structures that underlie these science and technology. Through quantitative analysis, it is to find out who the main research actors are, what research areas are being dealt with, which research areas last a long time, which areas have been discontinued, and which research areas are receiving new attention. In order to detect major research areas and intellectual bases in North Korean science and technology, North Korean scientists' articles were collected from WoS (SCIE). CiteSpace, a scientific quantitative analysis tool, was used to identify major research areas based on author simultaneous citation analysis. The main research areas in North Korea are found to be material properties, vibration analysis, incline matrice, sodium cointercalation, and external magnetic field.

To address environmental challenges and improve energy efficiency, the adoption of electric vehicles has led to a surge in related research. However, to comprehensively understand the research trends within the field of electric vehicles, it is necessary to systematically analyze vast amounts of data. This study systematically analyzed research trends in the field of electric vehicles and identified key research topics through LDA topic modeling, based on 36,519 papers related to electric vehicles collected from the SCIE database. The data analysis revealed a total of 10 major topics, of which three were identified as hot topics showing an upward trend: Electric Vehicle Charging Infrastructure, Energy and Environmental Policy, and Optimization and Algorithms. Conversely, five topics were identified as cold topics exhibiting a downward trend: Battery Temperature and Cooling, Battery Materials and Chemistry, Motor and Mechanical Design, Control Strategies and Systems, and Battery Components and Materials. This study provides basic data for understanding the current research trends in electric vehicles and offers valuable information for researchers in selecting research topics related to electric vehicles.

계수적 구간 불확실 플랜트를 안정화하는 강인 제어기의 설계의 방법으로서 고정차수 극 배치(FOPA : Fixed Order Pole Assighnment) 알고리즘을 이용할 수 있다. FOPA 알고리즘에 의해서 강인제어기 계수의 집합은 선형제약조건으로 표현되고, 이 조건을 만족하는 임의의 한점은 주어진 불확실 시스템을 안정화한다. 본 논문에서는 선형제약조건으로 주어진 제어기 계수의 집합에서 외란의 에너지를 최소화하는 제어기를 구하는 알고리즘을 제안한다. 일반적으로 전역 최적해을 구하는 문제는 BMI(bilinear matrix inequalities)로 표현되지만 제어기의 계수를 고정했을 때는 LMI(lineal matrix inequalities)로 간략화되기 때문에 제어기계수에 대한 최소화와 성능지수에 대한 최소화를 반복함으로써 국부 최적해를 구할 수 있다. 제안한 알고리즘의 효용성을 보이기 위해 제어기 설계 예를 보이고, 그 성능을 비교 분석한다.

과학기술 학술활동은 원천기술 확보의 기반인 기초연구를 강화하기 위한 핵심요소이다. 논문과 학술지는 학술 커뮤니티에서 사전 연구기획과 사후 결과 활용의 핵심 수단으로써 중요한 기능을 담당하며 과학기술과 함께 발전해 왔다. 따라서 학술지 종수와 논문 발표 건수, 피인용 현황은 해당 주제 분야의 동향을 파악하는데 매우 중요하다. 이 연구에서는 최근 11년간 JCR 과학기술 주제분야(176개)별 논문 편수와 피인용도 증감 변화를 조사하여 새로운 주제분야(학문)의 생성과 성장가능성을 살펴 보았다.
