The purpose of this survey-based study was to investigate high school students' perceptions of mathematics teachers' implementation of Universal Design for Learning (UDL)-based practices and technology in their mathematics classes in 2017. A total of 303 high school students in South Korea participated in this online survey on teachers' use of technology for instructional practices, the frequency of technology tool use, and the meeting of UDL guidelines in mathematics instruction. According to frequency analysis, high school students generally perceived their teachers' mathematics teaching as somewhat positive in providing multiple means of representation, action and expression, and engagement. However, mathematics teachers' implementation of technology tools in their mathematics classes was generally limited. This study indicated significant and positive relationships between variables regarding the use of technology tools and teachers' efforts to follow the UDL guidelines. Applying the Chi-squared test, we further examined how each survey result differed according to high school students' academic achievements and grade levels.

Today we seem to be flooded with digital culture as the age of information has reached its peak. As fusion culture has been generalized, in which the arts and culture of the East and the West are in harmony, and quality of life has been improved, people are enjoying more abundant cultural benefits than ever. In such a situation, we may lose the origin of our culture and disregard our traditional culture due to the mixture of cultures. In addition, it is necessary at this point to distinguish pure culture from mixed one and to re-illuminate the value of our original culture for the next generation. Therefore, the author took interested in Dongraeyaryu, a large-scale festival in Busan, which has been designated as an important intangible cultural property, and carried out a research for its continuous instruction and activation. among contents such as music, costume, dancing and stage properties that compose intangible cultural property, this study selected costume, which has significant visual effects and large differences in shape between old one and contemporary one, for development. By proposing modernized design of costume preferred by the new generation and in harmony with the masks, this study wished to narrow the generation gap, to direct young people's attention to the learning of tradition and to propose motives that activate the culture of local festival.

Scan techniques are almost mandatorily adopted in designing current System-on-a-Chip (SoC) to enhance testability, but inadvertently secret keys can be stolen through the scan test channels of crypto SoCs. An efficient scan design technique is proposed in this paper to protect the secret key of an Advanced Encryption Standard (AES) core embedded in an SoC. A new instruction is added to IEEE 1149.1 boundary scan to use a fake key instead of user key, in which the fake key is chosen with meticulous care to improve the testability as well. Our approach can be implemented as user defined logic with conventional boundary scan design, hence no modification is necessary to any crypto IP core. Conformance to the IEEE 1149.1 standards is completely preserved while yielding better performance of area, power, and fault coverage with highly robust protection of the secret user key.

This stduy aimed to suggest a possible way for a new setting of interior design education through analyzing educational situations of domestic interior design societies. The study showed that interior design education should not follow expressive methods made from practical work which had been popular in the past and it should establish fundamental formation to make interior design education useful in industrial fields through active educationalindustrial complex. Interior design education is not possible without interrelationship with other professional fields and cooperative attitudes among them. The rapid development in the modern industrial world and the ever-growing information processing world regardless of ideology and regiional boundaries indicate that the future of interior design education will be no longer effective with traditional education systems. The idea suggested in this study may be understood as a bridge between the educational reality and its ideal in interior design teaching. The main points of the study are follows. First, the projects of advanced interior design should be focused on increasing the ability for problem solving rather than accumulating basic knowledge. Second, motivation is important for the maximization of the efficiency of educatiov. Therefore a few suggestions in establishing design conditions, as strategies of inducing 'attention', 'self-confidence', 'satisfaction', and 'relevance' are closely examined to propose practical application methods. Third, educational methods should be developed towards creativity in order to increase abilities of thinking and expressiov. Finally, it is necessary to explore various device which help internship participants to get experiences with a sense of practical situations in industrial fields. This could be possibly done by enforcing academic grades for the work done as an internship participation; by employing workmen in industrial fields as faculty members; and by bringing faculty members into actual industrial situations and providing workmen with lectures. A new approach for a better design education seems to be desirable for the future.

Unlike in the past, where the expression of the form was given a priority, with the widening of the scopes of the designs, the proportion of design education institution curricula targeting user experience and the application of technology is continually and gradually increasing. Open source microcontroller boards such as Arduino have initiated attracting attention as a countermeasure against these changes. These prototyping tools have many advantages for the diversification of expression and design verification in the design field and therefore have a high likelihood of being introduced into many design education institutes; however, the tools act as high entry barriers for design students who lack engineering knowledge. Although various educational content and tools have been developed to address the issue of barrier, existing solutions remain insufficient as alternatives for the purpose of activation. In this study, we investigated the present state of related education content and conducted a pilot workshop using a prototype microcontroller board with simplified coding. We intend to use the results of this investigation to develop study material for design education. We started by conducting a survey regarding the pre-university education situation. It was observed that engineering education opportunities are insufficient and the problem of mutual application between educations due to course-based education was not realized. We also analyzed the characteristics of simplified training tools using the microcontroller to establish a direction for educational design and conducted a pilot workshop using the microcontroller toolkit with a simplified coding process based on this content. Students who lack a basic knowledge of engineering technology received instruction, and after completing minimum preliminary training, they proceeded to practical exercises that involved utilizing the toolkit. Through this process, we identified the need for a simple-type microcontroller board with low-complexity for use in educating students majoring in design. We also identified some obstacles that serve as barriers to entry of utilizing microcontroller board. Based on these results, we propose several functional requirements and teaching guidelines for prototyping toolkits for design education.

The purpose of this study was to develop practical problem-based home economics teaching.learning process plans about a unit 'the youth and consumer life' of middle school eighth-grade Technology and Home Economics by applying blended learning(BL) strategy. According to ADDIE instructional design model, this study was conducted in the following procedure: analysis, design/development, implementation, and evaluation. In the stage of design and development, the selected unit was converted into a practical problem-based unit, and practical problem-based teaching. learning process plans were designed in detail by using BL strategy. An online study room for practical problem-based home economics instruction grounded in BL strategy was prepared by using Edunet(http://community.edunet4u.net/${\sim}$consumer2). Eight-session lesson plans were mapped out, and study aids for students and materials for teachers were prepared. In the implementation stage, the first-session teaching plans that dealt with a minor question 'what preparations should be made to become a wise consumer' were utilized when instruction was provided to 115 eighth graders who were in three different province, and the other one was in a middle school in the city of Daejeon. The experimental teaching was implemented for two weeks in the following procedure: preliminary program, pre-online learning, main instruction and post- online learning. The preliminary program was carried out in a session in the classroom, and pre-online learning was provided before the main instruction was given in a session in the classroom. After the main instruction was completed, post-online learning was offered. In the evaluation stage, a survey was conducted on all the learners and teachers to find out their opinions and suggestions.
