The environment of IT is, currently, on its developing process to the period of cloud computing, big data, and business intelligence which not only enable computer and internet to be utilized like the water or the air, but also be a new motivating force for its advance. In the respect of various interactions and Infographics, however, it is requiring more demands from its users, and additional functions which cannot be provided by the Web Browser. In this study, therefore, it will be suggested a design of N-screen convergence presentation tier by using infographics based on N-Tier platform.

Modern times are called 'the system and fusion era'. One system has been compounded with the other system repeatedly, and the new systems form a great mixed system again and again. Discrete electronic devices have been integrated as one semiconductor system and have been unified as a great mixed system frequently. This study proposes a module based 2-year college electronic engineering curriculum focused on system and integrated circuit design. This curriculum is devised to be suitable for the industrial environment, especially in the school-industry cooperation, and is recomposed to promote the organic union of interdisciplinary courses. The newly designed course has been developed as a multi semester module model which enables a practical field training and in-depth study.

빠른 속도로 끊임없이 쏟아지는 정보의 홍수 속에서 미국이나 영국 등 세계 각 나라마다 앞으로 미래사회를 이끌어 갈 인재가 갖추어야 하는 핵심 역량의 하나로 창의적 문제해결력을 들고 있는데, 이러한 추세는 교육계에서도 예외 없이 나타나고 있어 학문의 각 영역과 정보 기술 활용의 융합된 교육 방법론에 대한 관심이 날로 고조되고 있다. 이러한 융합된 교육 방법론의 필요와 창의적 문제해결력 향상을 위한 교육으로 소프트웨어 교육이 우리나라를 포함하여 전 세계적으로 교육과정에 포함될 정도로 중요성이 더해가고 있다. 전 세계적인 정보교육의 패러다임 변화에 따라 우리나라도 교육부에서 '2015 개정 교육과정'에 소프트웨어 교육을 포함시키고, 소프트웨어 교육의 목표를 '컴퓨팅 사고력을 가진 창의 융합 인재를 기르는 데에 목표가 있다'라고 발표하였다. 또한 소프트웨어 교육의 방향과 운영에 필요한 내용들 중에 교육 현장에서 소프트웨어 교육을 하기에 부족한 소프트웨어 교육 시수의 적절한 확보와 교수 학습 방법의 연구가 필요한 것으로 발표하였다. 이에 본 연구는 부족한 소프트웨어 교육 시수의 해소와 여러 교과 간의 융합적인 교수 학습 방법을 위한 효과적인 소프트웨어 교육 수업 모형을 설계하게 되었다.

2015년부터 NIST에서는 경량 암호 공모전을 개최하여 저사양 기기에서 활용할 경량 암호 알고리즘을 개발해오고 있다. 본 논문에서는 경량 암호 공모전에서 발표된 Romulus 암호에 활용되는 Tweakey 프레임워크로 설계된 Tweakable 블록암호 Skinny의 최적화 구현을 최신 프로세서 중 하나인 Apple M1 프로세서 상에서 진행하였다. M1 프로세서는 ARMv8 아키텍처로 설계되었으며, ARMv8 벡터 명령어 중 TBL 명령어를 활용한 라운드 함수의 효율적인 구현으로 최적화를 진행하였다. Skinny 블록암호의 블록 길이 128-bit 구현을 진행하였으며, 해당 프로세서에서 구현된 skinny 구현 연구가 없기 때문에 Referenc C코드와 비교를 진행하였다. 성능 측정 결과 128-bit 키 길이에서는 약 19배의 성능 향상을 확인하였으며, 키 길이 384-bit에서는 약 32배의 높은 성능 향상을 확인할 수 있다.

In the society where the paradigm of knowledge is rapidly changing and developing, convergence emphasizing the connection between knowledge and technology in various fields is significant. In order to cultivate these creative-convergent talents, STEAM(Science, Technology, Engineering, Arts, and Mathematics) is being considered important to make them equipped with creative thinking ability and core competence required in the future society and help them devise new ideas escaping from the branches of study. This study is about convergence instructional design of computer with marketing subject, which aims to foster talent. The results of this study are as follows. First, the structured process of convergence lessons. Second, the convergence lesson was based on a cyclic process with steps : selection of the subject concerned, selection of a topic, designing the lesson, mapping out the lesson plan and developing problems, having a final discussion on the whole lesson, performing the lesson and evaluating the lesson. Third, the development of the problems about the introduction of computer engineering and Internet marketing subject for convergence lessons. To make an effect of this model, studies applying this instructional design to many lectures should be implemented.

Design patterns can be classified as software reuse technique that might provide effective solutions to specific problems that occur repeatedly in software development. In particular, object-oriented design patterns are incorporated into various software platforms and frameworks to increase software productivity. This paper aims to support general guidelines relating to design patterns for Android-based game programming. The proper use of the design pattern could be effective in not only for software development productivity, but also for post-development software maintenance. This paper provides fundamental procedures and case studies for applying design patterns to game programming on the Android platform. Typical object-oriented design patterns such as MVP, Singleton, Observer, and State have been applied to the development of Android game programs.

Recently the navigation service and LBS (Location based Services) using map supports much information services on mobile terminal. Also Internet Web sites support user much information. But, the user has the difficulty for acquiring the service and the various information based on map because of searching the many Internet sites. Accordingly, this paper supports a convergence information service model of various culture, education, tourism, sport and traffic for accessing synthesizing information based on map. And we design and implement this model using 공개 API. We present a convergence information service model of culture, tourism, sport and bus line information form tour destination and cultural place of Jeju province using the model. Additionally, we develop this service model using apache web server on Linux environment, PHP and JavaScript, MySQL database and Map 공개 API. As this service model supports a convenience action of culture and tourism for Jeju islanders and tourists.

IoT which is the core IT of the 4^th industrial revolution, is providing various services from users in the conversion with other industries. The IoT convergence technology is leading the communication paradigm of communication environment in accordance with the increase of convenience for users. However, it is urgently needed to establish the security measures for the rapidly-developing IoT convergence technology. As IoT is closely related to digital ethics and personal information protection, other industries should establish the measures for coping with threatening elements in accordance with the introduction of IoT. In case when security incidents occur, there could be diverse problems such as information leakage, damage to image, monetary loss, and casualty. Thus, this paper suggests a certificate management technique for safe control over access in IoT-based Cloud convergence environment. This thesis designed the device/user registration, message communication protocol, and device renewal/management technique. On top of performing the analysis on safety in accordance with attack technique and vulnerability, in the results of conducting the evaluation of efficiency compared to the existing PKI-based certificate management technique, it showed about 32% decreased value.

The purpose of this study was performed to examine the effects of simulation integrated with problem based learning(S-PBL) on self-leadership, critical thinking disposition, goal commitment for nursing students. The design was a one group pre-post test. The subjects consisted of one group of 90 fourth year nursing students of K Colleage. The period for this study was from March to June in 2019. The collected data were analyzed by Paired t-test, Pearson correlation coefficient. This study showed significantly higher self-leadership(t=-16.22, p<.001), critical thinking disposition(t=-11.36, p<.001), goal commitment(t=-7.06, p<.001). There was a significant positive correlation between self-leadership and critical thinking disposition(r=.438, p<.001), self-leadership and goal commitment(r=.285, p<.001). In conclusion, this study show that integrated with problem based learning(S-PBL) can be used for improvement the self-leadership, critical thinking disposition, goal commitment. It is suggested to check the effect of simulation integrated with problem based learning applying various nursing situations in the future.
