Poly(urethane acrylate) siloxane oligomers with Interpenetrating polymer networked nanoparticles were prepared to synthesize hard coating solution by reaction with isophorone diisocyanate(IPDI) of 1, 2, 3, 4 phr. The structures and molecular weights of the synthesized solutions were characterized by IR spectroscopy and gel permeation chromatography, respectively. In the cross-cut test for the adhesion, all the solutions showed good adhesion of 5B regardless of the content of IPDI and film thickness. The addition of 1 phr IPDI resulted in the best pencil hardness. The IPDI combined siloxane hard coating solution showed more flexibility than the siloxane solution. These results will yield the improvement in the siloxane solution using for plastic display plate.

The study aims to discover the scope of pre-service special education teachers' knowledge and perceptions of using computer technology in teaching students with disabilities from a pre-service teacher (PST) perspective in light of the gender and sub-major variables. The sample consisted of 84 MEd students/pre-service teachers at the Department of Special Education, Faculty of Education, Umm Al-Qura University. The descriptive analytical approach is used due to its relevance to the study. A survey consisting of the participant's basic information section and 12 statements was sent to a set of pre-service teachers. Findings showed that pre-service special education teachers had an overall high knowledge of using computer technology (M=3.93). Findings also indicated that there were no gender- or major-related statistically significant differences (α = 0.05), in pre-service special education students' knowledge and perceptions of using computer technology.

This study aims to analyze the impact of technology adoption on students' satisfaction with the higher education system in Vietnam. With the continuous development of information and technology, the education sector in particular and many economic sectors in Vietnam have witnessed an explosion of applications and interventions in teaching-learning. However, these innovations have also received a lot of criticism regarding their effectiveness and feasibility. Although the numerous benefits that technology adoption has brought to education are apparent, many practitioners have not adjusted to this transition, resulting in lower learner satisfaction. Through a survey of more than 2472 university students in Vietnam, the results find a positive relationship between technology adoption and student satisfaction in higher education. We also test how nine contingent factors including gender, income, major, self-study time, learning methods, technology administration, self-ability in adopting technology, technology accessibility, and purpose of using technology can moderate that relationship. Indeed, technology adoption acts as a facilitator to make learning more convenient, effective, and accessible, rather than completely affecting learning outcomes and satisfaction. This result suggests that self-motivation is an important and decisive factor in improving satisfaction through choosing and applying technology effectively and appropriately.

디지털 테크놀로지 시대에 새로운 가치를 추구하려는 노력은 사회 문화 전반 분야뿐만이 아닌 일반 교육계와 문화, 예술교육에도 변화를 요구하고 있다. 가장 큰 변화의 하나는 다른 영역간의 통합과 연계라는 추세가 문화와 예술분야에도 영향을 주면서, 문화와 예술이 통합을 이룬 문화예술 교육을 탄생하기에 이르렀다. 또한 새로운 시대는 디지털 테크놀로지의 활용이 교육 전 영역에서 활발히 사용되고 있으며, 문화 예술교육에도 테크놀로지의 활용이라는 새로운 시도를 요구하고 있다. 본 연구는 음악 테크놀로지를 활용한 문화예술교육에 대하여 이론적으로 알아보았다. 음악 테크놀로지의 활용은 다른 교과간의 통합적 접근으로의 가능성을 보여주며, 문화예술교육 외에 다양한 학문에도 적용이 가능함을 보여주었다. 음악 테크노로지의 활용은 현재 문화예술 교육 분야의 독특성, 전문성, 고유성을 반영해줄 만한 교수학습방법의 학습도구로서 다양한 대상과 상황에서 적용하여 실천적 사례를 쌓음으로서 문화예술 교육 분야를 위한 새로운 교수학습방법으로서의 역할을 할 수 있으리라 생각한다.

A novel pulse fitting analysis (PFA) method is presented for the acquisition of nuclear spectra. The charging process of the feedback capacitor in the resistive feedback charge-sensitive preamplifier is equivalent to the impulsive pulse, and its impulse response function (IRF) can be obtained by non-linear fitting of the falling edge of the nuclear pulse. The integral of the IRF excluding the baseline represents the energy deposition of the particles in the detector. In addition, since the non-linear fitting process in PFA method is difficult to achieve in the conventional architecture of spectroscopy system, a new multi-channel analyzer (MCA) based on Zynq SoC is proposed, which transmits all the data of nuclear pulses from the programmable logic (PL) to the processing system (PS) by high-speed AXI-Stream in order to implement PFA method with precision. The linearity of new MCA has been tested. The spectrum of ¹³⁷Cs was obtained using LaBr₃(Ce) scintillator detector, and was compared with commercial MCA by ORTEC. The results of tests indicate that the MCA based on PFA method has the same performance as the commercial MCA based on pulse height analysis (PHA) method and excellent linearity for γ-rays with different energies, which infers that PFA method is an effective and promising method for the acquisition of spectra. Furthermore, it provides a new solution for nuclear pulse processing algorithms involving regression and iterative processes.

The Korean Society for Engineering Education (KSEE) has been conducted scholarship meeting, workshop, and publicated academic journal, Engineering Education Research, since 1998. Kim Jin-soo analysed 'Engineering Education Research' on methods of research and contents. However, there are an in crease in quantity since then, it needed to analyse and arrange. This study analysed all 417 papers which were published from 1998 to 2012. The conclusion is as in the following. First, the number of collections published has been increasing up to 6 per year. 75.5% of the lead author's institution are universities, and Engineering Education Innovation Center researcher has been increasing steadily up to 8.9%. Research about Engineering Education Methods and Programs are being mostly studied. Apart from classified field in this, a study on the psychological characteristics of technology students are being steadily researched. In papers, the literature/development research method is used the most frequently (54.6%), the research study (39.9%) is the next and the experimental research method (5.5%) is followed by. Since 2006, study using the experimental research method is the growing lately. Second, characteristic of study between institution of lead author, a field of study, a number of study and methods of research by cross analyzing. The result is as in the following. In case of university and Engineering Education Innovation Center researcher studied much more about Engineering Education Methods and programs, research laboratory researcher tend to study about Engineering Educational Philosophy and Policy. Also, foreign researcher tend to introduce Engineering Education Example and Lecture. In case of university and foreign researcher used the literature/development research method frequently. Engineering Education Innovation Center and research laboratory and school researcher used the research study much more. There is no difference between a field of study and research methods. Finally, research strategies and new direction for improving the engineering education journal's papers at the section of discussion and suggestion were suggested.

Problem solving in real life is a core competency commonly adopted in several subjects recently. The real-world problems were rarely resolved with only one domain of knowledge. Thus, convergence education is becoming a trend in many countries. As on-line education is revitalized because of COVID-19, the need for changes to STEAM education is emerging. In December 2019, the on-line education systems quickly settled in schools because of COVID-19. During the first semester of 2020, most school education was conducted as virtual/distance learning classes. It is necessary to analyze how much technology has been used in the STEAM classes in Korea. This paper analyzes the research papers related to the STEAM education in Korea conducted in the last 10 years. By doing this, we analyze what kind of edutechs we were interested in, what kind of STEAM education actually occurred, and to whom it was conducted. The previous research papers analyzed in this paper are the papers in the Korea Citation Index accredited journals and candidate journals. Finally, this paper proposes educational changing factors to be considered for future technology-based STEAM education.
