The purpose of this study is to present a model for fusion education combining engineering elements based on humanistic writing. Instruction design in presentation writing for engineering education progresses consists of four steps, such as instruction in visual, teamwork, feedback, and rewriting. Following these steps help engineering school students to analyze important data and to communicate their creative ideas. As writing is proceeding step by step, instruction design for presentation writing should come forth with specific methods to make students practice.

The purpose of this paper is to develop a technical writing model suitable for engineering students based on the practice of technical writing using the patent application form for engineering students. The Dick & Carey model was used to design the teaching of technical writing using the patent application form. In particular, the instructor communicates with the learner and instructs the learner to produce and express students' own ideas. Instruction design in technical writing progresses consists of four steps, such as creating ideas by brainstorming, comprising contents, exercising writing, and feedback. Feedback occurs between an instructor and a learner and also does among students. As writing is proceeding step by step, instruction design for technical writing should come forth with specific methods to make students practice writing in work. Following these steps will help engineering school students to make up new products after graduating university.

Most of multimedia processors for 2D/3D graphics acceleration use a lot of integer/floating point arithmetic units. We present a new architecture with an efficient ALU, built in a smaller chip size. It reduces instruction cycles significantly based on a foundation of multi-thread operation, variable length instruction words, dual phase operation, and phase instruction's coordination. We can decrease the number of instruction cycles up to 50%, and can achieve twice better performance.

The purpose of the study was to develop the Arduino based STEAM instruction materials for creative engineering design class. PDIE model was used in this study. We developed a STEAM lesson plan and a STEAM lesson worksheet for a total of six sessions through the steps of preparation, development, implementation and evaluation. The validity of the instruction materials was evaluated by the 10 experts using a survey. The instruction materials were applied to the class (52 students attended) of the creative engineering designs unit in technology and home economics subject. The class satisfaction and the creative solving-problem ability were examined after the calss. The class satafacition was high as the average of 10 item was 4.57 (out of 5). The paired t-test was conducted to compare the means of the creative solving-problem ability. It was observed that 'understanding and mastery of knowledge, thought, function and skills in a specific domain', 'divergent thinking', 'critical and logical thinking' and ' motivational factors' were significantly increased after the class. The instruction materials develped in this study were successfully designed to enhance the creative solving-problem ability by designing creative tasks and to intrique the interest by adding visual and auditory stimuli with the Arduino.

최근 OpenGL ES 2.0이 개정됨에 따라 모바일 기기에 Shader 3.0모델을 지원 가능한 프로세서가 요구된다. 이 쉐이더 3.0 모델의 지원과 관련하여 명령어의 길이의 증가가 필요하고, 이는 메모리 용량의 증가를 초래한다. 본 논문에서는 가변길이 구조와 유닛구조를 채택한 새로운 명령어 구조를 제안한다. 이 명령어 구조는 쉐이더 3.0 모델을 지원하고 명령어 필드 낭비를 줄일 수 있도록 최대 4개의 32비트 유닛 명령어가 가변적으로 조합되어 수행된다.

Instructional contents are used to demonstrate a technical process to teach and walkthrough certain procedures to carry out a task. This type of informational content is widely used for teaching and lectures in form of tutorial videos and training videos. Since there are questions and uncertainties for what could be the killer application for the novel wearables, we propose a self-instruction training application on a smart glass to utilize already-available instruction videos as well as public open data in creative ways. We design and implement a prototype application to help users train by wearing smart glasses specifically designed for two concrete and hand-constrained use cases where the user's hands need to be free to operate. To increase the efficiency and feasibility of the self-instruction training, we contribute to the development of a wearable killer application by integrating a voice-based user interface using speech recognizer, public open data APIs, and timestamp-based procedural content navigation structure into our proof-of-concept application.

The purpose of this study was to analyze of how the elementary school teachers lead their classes of a science laboratory instruction and an engineering laboratory instruction in a science subject class. For this study, science laboratory and engineering laboratory lessons were selected and for each science and engineering laboratory lesson, five elementary school teachers were video-recorded of their lessons. The science and engineering laboratory lessons were analyzed by utilizing processes of the science model and the engineering model based on Schauble et al. (1991). The results of these studies are as follows: In science laboratory instruction, some participants didn't distinguish the difference between the science laboratory goal and the engineering laboratory goal. All of participants used search and end strategy of engineering laboratory for science laboratory lesson. In engineering laboratory instruction, all of participants guided to students engineering laboratory goal and used inferences and search strategy of engineering laboratory. However they didn't use the trial and error strategy or redesign which can be an essential element in engineering and design process. Educational implications are discussed.

본 논문은 공학인증 프로그램의 필수 과목인 창의공학설계 교과목 수업을 통해 학생들의 창의력을 향상시킬 수 있는 설계 수업 방안을 연구 하였다. 공과대학 학생들로 하여금 설계과제의 선호도와 문제점을 조사 하였고 이를 활용 하여 설계 과제 수업에서 구조물의 완성을 통한 창의력 증진 수업에 주력을 하였던 것을, 다학제간 융합에서 기계적 메커니즘의 결정체인 루브 골드버그(Rube-Goldberg) 창치를 활용한 '가장 간단한 작동을 가장 복잡한 기계 장치로 작동' 시키는 구조물의 완성을 통하여 기존의 설계과제를 복합적으로 활용하는 새로운 설계 과정 교육 개발안을 제언하였다.

The purpose of this study is to develop Raspberry Pi-based CanSat instruction materials for liberal arts classes to be used in university space education. The educational satellite simulation program is developed by applying the ADDIE program consisting of analysis, design, development, execution, and evaluation of 15 lessons per semester. The usefulness of the instruction materials is evaluated by a validity test of a total of 6 experts. The proposed materials are applied to 100 college students from various majors. To analyze the impact on creative problem-solving ability, a questionnaire is conducted before and after class, and as a result, it is confirmed that there is a significant improvement in all areas after class. The class satisfaction survey is conducted for a total of 10 questions, and the average score is 4.41 out of 5, which is high. In conclusion, the proposed instruction materials make it possible to achieve successful space education using Raspberry Pi and improve creative problem-solving ability in universities.

This paper describes the design and implementation of an application specific instruction-set processor developed for embedded DSP applications. The instruction-set has an uniform size of 16 bits, and supports 3 types of instructions: Primitive, Complex, and Specific. To reduce code size and cycle count we introduce complex instructions that can be selected according to the application under consideration, which leads to 50% code size reduction maximally. The processor has two independent data memories to double the data throughput and the address space. The processor is synthesized by 0.6$\mu$m single-poly double-metal technology. Critical path simulation shows that the maximum frequency is 110MHz and total gate count is 132, 000.
