본 연구는 사회 연결망 분석 기법(SNA)을 통하여 최근 10년간 중국대학의 과학연구 및 개발의 효율성 평가현황과 연구동향을 파악하는데 목적이 있다. 분석에 사용된 자료는 중국의 CNKI 학술 자료집에서 589개의 논문을 추출하여 과학 연구 개발 효율성 평가와 직접적으로 관련된 190개의 논문을 선택하여 분석하였다. 분석 결과 중국대학의 과학기술 연구 효율성 평가 현황, 연구 트렌드 파악, 과학 연구개발에 미치는 주요 요인 및 과학연구의 교류를 촉진하는 주요 요인을 확인할 수 있었다. 본 연구는 대학의 과학 연구 개발을 촉진하고, 과학 연구 관리를 강화하며 지식 교류를 촉진하는 긍정적인 의미를 제공할 수 있다. 이 연구는 실제 중국 연구 환경의 과학 연구 동향을 종합적으로 분석하는 데 한계가 있다. 후속 연구는 중국과 다른 나라의 동향을 비교할 필요가 있다.

본 연구는 자연구조 개념의 창의융합조형 교육프로그램 개발을 위한 기초연구로 관련 연구 동향을 파악하고자 하였다. 자연구조 개념은 프렉탈(fractal), 키네틱(kinetic), 바이오미미크리(biomimicry)로 한정하였다. 학술연구정보서비스를 활용하여 자연구조개념과 관련한 최근 10년간의 국내 연구동향을 분석한 결과, 편차는 있으나 교육 관련연구는 이 세 주제 모두 미흡하였으며 프랙탈의 경우는 수학 교과에 편중되어 있었다. 따라서 본 연구는 조형교육프로그램 개발을 위한 기초자료 조사이기 때문에 프랙탈, 키네틱, 바이오미미크리를 주제로 한 조형 관련 연구 동향을 추가로 분석하였고 이 세 주제가 다루어지고 있는 분야와 상세내용을 파악하였다. 자연의 가진 원천적 특성을 이해하고 무한에 가까울 만큼의 방대한 조형원리를 교육주제로 활용함은 매우 유의미하다 할 수 있다. 그러나 본 연구를 통해 자연구조개념의 교육프로그램이 매우 미흡함을 파악하였기에 후속으로 국외에서의 자연구조개념을 주제로 한 교육 관련연구동향을 살펴보고 체계적 창의융합조형교육프로그램 개발을 위한 기초자료로 활용하고자 한다.

This study aims to analyze research trends related to the exhaustion of hotel employees and social workers and present the tasks and directions of future exhaustion research for hotel employees and social workers. To this end, 423 candidates for registration and registration of the Korea Research Foundation from 2012 to 2022 and master's and doctoral dissertations (178 papers) were analyzed according to the research period, research topics, research subjects, and research methods. As a result, from 29 papers in 2012, 49 studies were published in 2013, and 53 studies in 2020, indicating that they are gradually rising. Second, job burnout was the highest among hotel employees and social workers, followed by interpersonal relationships, practice, career, techno, safety accidents, and job burnout. Third, hotel employees and social workers were the highest among the subjects related to the exhaustion of hotel employees and social workers, followed by hotel employees and social workers. Fourth, quantitative research was conducted the most as a method for the exhaustion of hotel employees and social workers, and qualitative research was conducted a lot. According to these research results the study suggests that it is necessary to rediscover the meaning of research on burnout of hotel employees and social workers, which directly affects hotel employees and social workers, and to find ways for hotel employees and social workers to feel less burnout.

Tactile sensors, which are commonly referred to as pressure and strain sensors, have been extensively investigated to meet the demands for attachable and wearable electronics for monitoring the health status or activity of human users. For this purpose, the introduction of two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs) with high mechanical strength at the atomic scale is very suitable for tactile sensors applicable for use in human-friendly devices. In this paper, we examine a descriptive summary of a tactile sensor and review state-of- the-art research trends of 2D material-based tactile sensors in terms of the material and architecture. Finally, we propose a roadmap for future studies into advanced tactile sensors based on our ongoing research.

It is challenging work to predict weather and climate conditions of the future in advance. Since ENIAC was developed, weather and climate research areas have been taking advantage of the improvements in computer hardware. High performance computers allows researchers to build high quality models that allow them to make good predictions of what might happen in the future. Statistics on the high performance computers are one of the major interest to not only manufacturers but also the users such as weather and climate researchers. For this reason, the Top500 Supercomputer Sites Report has been being released twice a year since 1993 to provide a reliable basis for tracking and detecting trends in high performance computing. Using the Top500 Report, a short review on the supercomputer trends in weather and climate research areas is provided in this article.

Objective: The purpose of this study was to explore research trends in childhood executive function in Korean academic journal articles. This study showed which population groups were studied, which factors of executive function were measured, and which domains were studied in the selected articels. Methods: A systematic review of empirical studies of childhood executive function published in Korean academic journals from 2006 to 2016 was conducted. Through searching the KERIS database, 60 empirical studies were selected for review. Results: The results of the analyses showed that the population group the most studied was normal young children and that factors of executive function most studied were inhibition, cognitive flexibility, and working memory. Conclusion: Based on this systematic review of empirical studies of childhood executive function, several suggestions for future research are addressed.

Deep learning is a promising solution to a number of complex problems based on its inherent capability to approximate almost all types of functions without the demand for handcrafted feature extraction. New wireless transmission and access schemes based on deep learning are being increasingly proposed as substitutes for existing approaches, providing a lower complexity and better performance gain. Among such schemes, a communications system is viewed as an end-to-end autoencoder. The learning process applied in autoencoders can automatically deal with some nonlinear or unknown properties in communications systems. Deep learning can also be used to optimize each processing block for required tasks such as channel decoding, signal detection, and multiple access. On top of recent related research trends, we suggest appropriate research approaches for communications systems to adopt deep learning.
