  • As a study on how the Neurofeedback training effects on young children's brain function and intelligence, first, this paper aims to verity the effect Neurofeedback training brings to the function of young children's brain. Second, through K-WPPSI IQ test, analyses how Neurofeedback training influences on the development of young children's intelligence. The subjects of this study were the 60 five-year children attenging J kindergarten in Cheon-an, experimnet treatment was performed according to Neurofeedback training guidance from Aprile 21 to December 12, 2008. It analyzes the states of brain waves before and after the Neurofeedback training, and performed the statistical analysis through t-test, using SPSS for Window(V.13.0) package. As a result of analysis, it was shown that firstly Neurofeedback training was very effective on the d!evelopment of infan's brain intelligence, since the quotient to evaluate the entire brain function appeared to have a meaningful influence. Secondly, it was proved that Neurofeedback training had much influence on the object assembly-area, the maze-area, and picture completion-area, and that it had the same influence on the performance intelligence quotient too. So, such results as these one make us realize that Neurofeedback training is a very effective method to the development of performance intelligence quotient. Thirdly, they indicate that Neurofeedback training hasn't a meaningful influence on verbal intelligence quotient, since it affects only on the similarities area among verbal intelligence quotient, the total evaluative quotient.

  • Owing to the unprecedented COVID-19 pandemic, the pharmaceutical industry has attracted considerable attention, spurred by the widespread expectation of vaccine development. In this study, we collect relevant topics from news articles related to COVID-19 and explore their links with two South Korean pharmaceutical indices, the Drug and Medicine index of the Korea Composite Stock Price Index (KOSPI) and the Korean Securities Dealers Automated Quotations (KOSDAQ) Pharmaceutical index. We use generalized Dirichlet-multinomial regression (g-DMR) to reveal the dynamic topic distributions over metadata of index values. The results of our analysis, obtained using g-DMR, reveal that a greater focus on specific news topics has a significant relationship with fluctuations in the indices. We also provide practical and theoretical implications based on this analysis.

  • The purpose of this study is to investigate the use of elements related to the competitive intelligence(CI) process, methods, and infrastructure in accordance with the degree of CI effectiveness of domestic firms and to propose a guideline for designing and operating an effective CI program in Korean films. The results of this study reveal that, for the elevation of CI effectiveness of Korean firms, it is important to actively utilize the overall CI process, including undisclosed information through human networks, public information through various media, and quantitative and qualitative analyses, an independent CI unit, various CI support systems, such as information and reward systems, and organizational culture of CI openness within an organization. However, CI outsourcing, CI primary objectives, and CI scale do not seem to have a significant influence on CI effectiveness of Korean firms. Based on these results, this research presents some important implications for effective competitive intelligence for Korean firms.

  • Recently, ICT environments have been increasingly developed and the pattern of the war also has been changed to NCW. The development of communication and network technology, for example, C4I and TDL(Tactical Data Link), has been prosperous and rapid. But the geospatial intelligence field which is the basis of the network frames relatively has not been developed. The purpose of this paper is to foster the geospatial governance in terms of the defense perspective. In order to do that, this paper deals with the U.S. Intelligence Community(IC) and the U.S. Army Global Information Grid(GIG), LandWarNet and those could be good examples of roles and statuses of geospatial intelligence. IC has been produced essential intelligence which is required for policymakers and military leaders. IC has several stove-piped intelligence process systems which have been separately developed and competed. And so as to complete GIG, the U.S. Army adopted LandWarNet. The U.S. Corps of Engineers organized the Army Geospatial Center(AGC) on 1 October 2009 to support LandWarNet. In order to develop NCW, we should recognize geospatial intelligence as the basis of network framework and make a central leading organization of defense geospatial intelligence. The mission of Korea Defense Geospatial-Intelligence Agency should be changed from producing GEOINT to a strategic GEOINT agency. The Army should organize a laboratory of geospatial intelligence field. The mission of producing GEOINT should be transferred to a geospatial intelligence battalion which is newly organized.

  • Digital edutainment games and educational content to the concept of combining learning and to draw conclusions that can be varied and fun learning program. Yet effective design. There's a lot of discussion about the systematic and scientific research, explore the difficult, but so is the growing field of endless possibility. Merely a linguistic capabilities of human intelligence and mathematical ability were measured primarily on issues raised in the traditional intelligence tests, and emerged a variety of multiple intelligences theory of human intelligence classified into 8 types and characteristics of each intelligence activities and guidelines for faculty are presented. These lessons are based on multiple intelligences theory professor activities through the design study for students to form learning activities to meet effectively and systematically conducted classes, and student-specific classes can be designed. In this study, multiple intelligences theory, based on children's edutainment content by linguistic intelligence, and intrapersonal intelligence body-kinestic intelligent and can learn by linking to content that was designed. Children interested in animation and gaming content through the feeling that you can become stiff in Korean alphabet education to solve the quests were designed to be a natural puleonagal.

  • 혼합 중요도(mixed criticality) 시스템은 안전에 중요한 기능을 우선시하도록 하는 추가적인 안전 요구사항이 존재한다. 그러나 기존 실시간 시스템의 설계로는 이를 만족하지 못하며, 높은 중요도 태스크가 다른 낮은 중요도 태스크로부터 간섭을 받아 데드라인 미스와 같은 문제를 일으키는 중요도 역전(criticality inversion) 문제가 발생할 수 있다. 이러한 중요도 역전 문제를 해결하기 위해 주기 변환(period transformation) 기법을 사용할 수 있지만, 스케줄링 오버헤드의 증가로 인해 오히려 전반적인 태스크의 응답시간이 증가하는 또 다른 문제가 발생하게 된다. 본 논문에서는 주기 변환과 스케줄링 오버헤드 간의 트레이드오프 관계를 설명하고, 실시간 리눅스 시스템에서 해당 문제점을 재연한 후 주기 변환의 적정선을 분석하고자 실험을 진행하였다. 그 결과, 중요도 역전 문제를 해결하기 위한 주기 변환을 그대로 적용할 경우, 문맥 교환이 48.7% 증가 및 스케줄링 오버헤드가 28.7% 증가로 인해 전반적인 응답시간이 증가하여 데드라인 미스가 다수 발생하는 결과를 확인할 수 있었다.
