This study aimed to present the tasks to solve digital divide by understanding the actual condition of the digital divide of persons with disabilities in South Korea. Moreover, It is considered that the factors about qualitative digital divide. As a result, it was found that "Information Utilization Capacity" and "Information Utilization" tend to be higher among the young, more often male, higher education level, higher income people who had some information technology education and experience using telecommunication services. In Addition, all failure type affected the "age", "income", "information technology education" in common. Among them, influence of "age" and "information technology education" has become stronger than the other variables. Therefore, in order to solve the qualitative digital divide, it is required to focus as "age" and "information technology education".

The core competencies for the 21st century are creativity, critical thinking, collaboration, and communication. In recent classes where ICT (information, communication, and technology) is grafted, a lot of efforts are also being made to increase such competencies. According to a research work, ICT is most often used as a communication channel between teachers and students or as an online collaboration tool among students. However, ICT has only played a role as a guideline for instruction, but not included in the curriculum until now. The research on methods how to integrate technology into teaching and learning is in full swing due to the development of technology and the advent of Covid-19. In this paper, we propose a technology integration hierarchy model, namely K-TIHM that can be combined with STEAM education. Since only learning environments have been proposed in the existing research for technology-based STEAM education, our model proposes a series of technology integration hierarchy that can be applied by school age along with STEAM. Also, we analyze the differences in among the Korea's ICT education operation guidelines, the Korea's Software education guidelines, and ours. The proposed model can help developing the primary and secondary school curriculum integrated with technology.

Human's sight holds the most extents among other senses. It will become more beneficial in person's emotion or body, if we form much better environment to human in connection with visual information as importance of visual information. Human is using a lot of display units on modern society. Basic colors that compose these are Red, Green and Blue. Using these three colors, we can change color sense of monitor or brightness degree. Suitable color degree by individual's environment can reduce person's stress or give comfortable feeling. So Factors by human's emotion and environment are standardized using fuzzy and the method that is to apply the result of Intelligent Color Control(ICC) on display is proposed.

Ubiquitous Computing System is available anytime, anywhere communications and computing systems, and information sharing and mutual cooperation between computing systems. in addition, For Ubiquitous Computing System, it is need the sensor technology to detect information of users and surrounding environment. For these reason, this paper proposed CRS(Context Recognition Switch) and DOS(Dynamic and Optimal Standard) based Context-awareness system architecture.

As the information society appears, the increasing power and access of personal computers along with wide spread use of the information technology has not only changed the landscape for communication but it has opened up new and exciting opportunities for education. One of the ways that information technology could help improve education is to be used in interactive communication to share the knowledge and experience of all the teachers as well as students. In this paper, the use and application of information communication technology[ICT] into mathematics classroom are described and showed several examples. furthermore, the web site design and developed for this study was introduced of the purpose of sharing the ideas about the knowledge and usage of the history of mathematics and examples of mathematical connections. The study suggests that enabling mathematics in incorporating of ICT by teachers and students requires more effort to be made in training teachers on the use and application of ICT into mathematics classroom.

대학에서 제공되고 있는 교육을 살펴보면 개별적인 학생들의 요구를 만족시키기 어렵다. 이는 대학교육이 한명의 서비스제공자에 의해 많은 사람들에게 동시에 제공되기 때문으로 볼 수 있다. 이를 감안하여 학생들이 보다 다양한 정보통신기술을 활용할 수 있다면 교육이 제공되는 과정이나 컨텐츠에 대해 더 만족할 수 있을 수 있다고 가정하였다. 연구에서는 학생들의 기술수용성 정도가 관계품질, 교육서비스품질, 교육서비스만족에 미치는 영향을 살펴보고 학생들의 정보통신기술의 활용정도가 높고 낮음에 따라 이들 관계에 어떠한 영향을 미치는지에 대해서도 살펴보았다. 검증결과 기술수용성이 높으면 관계품질, 교육서비스품질을 높일 수 있고, 관계 품질과 교육서비스품질도 교육서비스만족을 높일 수 있다고 제시되었다. 정보통신기술의 활용정도도 이들 관계에 영향을 미치는 것으로 나타났다. 본 연구는 교육인프라가 부족한 지방의 중소 도시에 위치한 대학에서 연구를 진행함으로써 향후 해당 컨텐츠를 교육에 활용하게 되었을 경우 더 많은 효과를 볼 수 있으리라 생각된다.

교육인적자원부는 정보통신기술 활용 교육을 주도해 나가는데 가장 중심이 되는 교사의 정보통신기술 활용 능력을 신장시키기 위해 다양한 방안들을 수립하여 추진하고 있다. 그러나 현재 시행되고 있는 교사의 정보통신기술 활용 능력 신장에 관한 대부분의 노력들은 정보통신기술을 교육활동에 효과적으로 활용할 수 있는 능력보다는 기술 소양 능력에 중점을 두고 있다. 본 연구에서는 교사의 정보통신기술 활용 능력에 관한 국내 외의 평가 도구를 비교 분석하고 각 도구의 장점을 바탕으로 교사의 정보통신기술 활용 능력 자기 평가 도구를 개발하였다. 본 평가 도구를 통해 실제 교수-학습 활동 지도 능력과 정보통신기술 활용 능력을 총체적으로 통합한 평가가 이루어질 수 있을 것이다.

An efficient molecular breeding technique for coffee plants was developed. In order to produce transgenic coffee plants, we established a model transformation procedure via Agrobacterium method. We isolated a gene encoding a protein possessing 7-methylxanthine methyltransferase (theobromine synthase) activity, and it was designated as Coffea arabica 7-methylxanthine methyl transferase; CaMXMT. Using this clone, we produced transgenic coffee plants, in which the expression of CaMXMT is suppressed by double-stranded RNA interference (RNAi) andlor anti-sense methods. The expression pattern of CaMXMT was analyzed by reverse transcription-PCR method and we found that, in the transformed cell lines, the level of transcripts were obviously suppressed by RNAi. The endogenous level of caffeine in the transformed cells was dramatically reduced in comparison with non-transformed cells.

In this paper, we propose a new implementation of a failure detector. The implementation uses a dual model of heartbeat and interaction. First, the heartbeat model is adopted to shorten the detection time, if the detection process does not receive the heartbeat message in the expected time. The interaction model is then used to check the process further. The expected time is calculated using the exponential smoothing method. Exponential smoothing can be used to estimate the next arrival time not only in the random data, but also in the data of linear trends. It is proven that the new detector in the paper can eventually be a perfect detector.

Big data, artificial intelligence (AI), and machine learning are keywords that represent the Fourth industrial Revolution. In addition, as the development of science and technology, the Korean government, public institutions and industries want professionals who can collect, analyze, utilize and predict data. This means that data analysis and utilization education become more important. Education on data analysis and utilization is increasing with trends in other academy. However, it is true that not many academy run long-term and systematic education. Korea Institute of Science and Technology Information (KISTI) is a data ecosystem hub and one of its performance missions has been providing data utilization and analysis education to meet the needs of industries, institutions and governments since 1966. In this study, KISTI's data education was analyzed using the number of curriculum trainees per year from 2001 to 2019. With this data, the change of interest in education in information and data field was analyzed by reflecting social and historical situations. And we identified the characteristics of KISTI and trainees. It means that the identity, characteristics, infrastructure, and resources of the institution have a greater impact on the trainees' interest of data-use education.In particular, KISTI, as a research institute, conducts research in various fields, including bio, weather, traffic, disaster and so on. And it has various research data in science and technology field. The purpose of this study can provide direction forthe establishment of new curriculum using data that can represent KISTI's strengths and identity. One of the conclusions of this paper would be KISTI's greatest advantages if it could be used in education to analyze and visualize many research data. Finally, through this study, it can expect that KISTI will be able to present a new direction for designing data curricula with quality education that can fulfill its role and responsibilities and highlight its strengths.
