우리는 기존 연구에서 NAND Flash Memory의 실시간 멀티 태스크 환경에서 응용프로그램의 실시간성을 보장하기 위한 페이지 교체 방법인 "mRT-PLRU(Multi-tasking Real-Time constrained combination of Pinning and LRU)"를 완성하였다. 이 페이지 교체 정책은 응용프로그램이 목표치보다 높은 확률도 데드라인을 만족 할 수 있도록 하기 위해서 응용프로그램의 코드페이지 프로파일링 작업이 우선시 되어야 한다. 하지만 응용프로그램 안에는 코드페이지 뿐만 아니라 데이터 페이지도 존재하고 있다. 이 논문은 이 부분에 주목하여, 기존의 코드페이지 프로파일링을 데이터 페이지 프로파일링까지 확장하였고, 프로파일링 결과물을 이용하여 mRT-PLRU 페이지 교체 정책을 데이터 페이지까지 다룰 수 있도록 개선된 방식을 제시한다.

This study identified what children's TV program model should KBS offer to the realization of the value of children audience. Results demonstrated that educational and norm, content diversity & children's interest, cultural diversity, and program accessibility were derived as the characteristics of children's programs pursued by parents bringing up children. This study further expects the efforts of KBS to provide children's programs that people want may serve as a key mechanism for enhancing awareness of the need for public broadcasting and contributing to the realization of normalizing TV license fees.

Importance of security system to prevent recently increased financial security accident is increasing. Biometric system between the security systems is focused. Fingerprint recognition has many useful aspects such as security, reliability and portability. In this treatise, fingerprint recognition technique is realized by using artificial neural network. Artificial Neural Network(ANN) is a mathematics learning model that makes specific patterns that a program can recognize to show a nerve network's characteristic on a computer. Input fingerprint images have a preprocessing process such as equalization, binarization and thinning. We extract minutiae feature in the images and program can recognize a fingerprint through ANN.

The application for PDA as a new wireless Internet device is variously developed to improve the function of PDA, and the application software must be installed to PDAs. In addition. when the power supply of PDA becomes fully discharged, all data stored in the RAM (Random Access Memory) could be vanished, and then the application programs should be reinstalled. This paper presents an automatic installation system of application program, PAIS (PDA Automatic Installation System). It is designed to solve the problem of PDA that PDA's users have to install the application programs on their PDA themselves. When this engine is applied, PDA users can save the time and effort for installation. It's convenient for the PDA users. The PDA and application software company can save the cost to create materials to explain the installation process.

As the proportion of non-contact work is increasing in the situation of COVID-19 pandemic, the collaboration program market is growing rapidly. As the size of the market grows, vulnerabilities in collaborative programs are constantly being disclosed which increases interest in the security of collaborative tools. In this paper, we introduce the results of vulnerability analysis on Electron-based collaboration programs, noting that a number of collaboration programs are based on the Electron framework, and propose countermeasures to enhance the security of Electron-based applications.

At a time when libraries are attracting attention as institutions and spaces that can foster future capabilities, this study conducts a general survey of the current status of public library programs related to the future capabilities and investigate the social awareness on libraries and future capabilities through big data analysis. As a result, first, programs are being planned and provided with the keyword of future capabilities, but most of them are limited to makerspace programs, edutech programs, and experience programs. Also, the detailed types of programs are limited to 3D print, coding, AR, VR, etc. In addition, current library programs related to future capabilities are not subdivided by each competency, these programs are provided in the comprehensive sense of future competency. Second, in the awareness survey through big data analysis, education, future capabilities, and libraries were found to be highly frequent, and it was seen that library reading, books, culture, and programs were related to strengthening future capabilities. Accordingly, in the future, libraries need to develop and provide systematic programs to cultivate future capabilities, and there is also a need to develop future capabilities improvement programs that take the life cycle into account.

In this study, the meta-analysis technique was applied to investigate the effectiveness of gifted education in non-cognitive areas. Studies conducted during the years from 2002 to 2012 were searched and then the outcomes from the 18 studies were used for meta-analysis. The statistically positive effects were in the leadership programs (the combined effect size=1.226, p<.001), in the career programs (the combined effect size=1.103, p<.001), in the programs related to social skills (the combined effect size=1.684, p<.001), in the programs for gifted students who show underachievement (the combined effect size=1.486, p<.001), and in the bibliotherapy programs (the combined effect size=0.613, p<.001) for the gifted. Implications of the study were discussed in depth based on the results.

컴퓨팅 사고력, 정보문화소양 및 협력적 문제해결력 함양을 목표로 하는 소프트웨어 교육, 즉 코딩 교육에 있어서 양질의 강사를 수급하는 것은 교육의 성패를 결정하는 중요한 문제 중 하나이다. 이러한 관점에서 초등학교의 방과후학교, 중학교 자유학기 등의 강사 수급 문제를 해결하기 위한 방법으로 다양한 코딩교육 전문강사 양성 과정이 주목을 받고 있다. 본 연구는 여성가족부와 각 지자체의 여성새일센터 등을 중심으로 개설 및 운영되고 있는 코딩강사 양성 프로그램의 운영 및 개설 현황, 운영 시간, 수강생 특성, 교육과정 등을 분석하고 시사점을 도출하는데 목적이 있다. 본 연구의 결과는 향후 코딩교육 전문강사 양성 프로그램의 개발 및 효과성 분석 등의 후속연구로 이어질 수 있다.

Advances in scramjet technology over the past 40 years odd have been remarkable, involving dramatic advances in hypersonic flight-demonstrated technologies. Especially, it is noticeable that since 1990s the international activity in scramjet development has increased considerably Strong scramjet development capabilities in developed countries are being created through many ongoing research programs for a new generation of industrial and military capability. In this paper the current status of scramjet technology is identified through the investigation of scramjet development programs of each developed country.

새로운 인터넷 응용 프로그램들이 등장하면서 망 중립성에 대한 논의는 계속되고 있다. 백본망 제공자의 입장에서 자신의 망에 부과를 주는 응용프로그램들 때문에 비용을 추가로 지불해야 한다는 사실은 오래된 문제이긴 하지만 새롭게 주목을 받고 있다. 많은 연구가 인터넷혼잡에 대한 문제 해결을 위해 가격체계를 도입해야 한다는 사실을 밝혔지만, 종량제 도입시도는 사회적 저항을 불러일으켰다. 하지만 IPTV나 VoIP와 같은 응용프로그램들이 요구하는 품질을 맞추기 위해서 망 투자는 계속되어야 하지만, 정치적 사회적 반대로 인해 사업자의 선택은 제한되어 있다. 한편 인터넷 버전 6를 위한 구축비용이 엄청나며, 새로운 표준 도입의 기술적 문제 때문에 많은 사업자들이 주저하고 있다. 이 논문은 우선대기열을 사용해서, 망 사업자가 무차별, 무계급(non-priority)에 기반한 인터넷에서 차별화된(prioritized) 인터넷 망 서비스를 제공할 때 일어날 수 있는 문제를 살펴본다. 현재의 서비스 수준보다 더 좋거나 같은 수준의 (즉 Pareto-improving) 서비스를 차별화된 가격체계에서 제공할 수 있을지에 대한 가능성과 문제점들을 살펴보면서, 망 사업자와 사용자 모두에게 유익할 수 있는 방안을 검토해 본다.
