90 년대 후반부터 웹 기반 수업(Web-based instruction)이라 하여 인터넷을 이용한 새로운 교육방법이 시도되었다. WBI에 필요한 각종 프로그래밍을 수작업으로 진행하여야 한다는 문제점을 극복하기 위해 개발된 학습운영체제(Learning Management System)가 개발되면서 인터넷을 통한 교육은 급속히 확산되고 있다. 무선 인터넷 기술까지 수용하는 개념인 소위 e-Learning 체제로 발전되면서 e-Learning의 수요는 급속히 증가하게 되었다. e-Learning 기술 표준 개발을 실질적으로 주도하는 기관들인 IEEE, AICC, IMS가 제안하는 개별 표준안들을 ADL에서 SCORM(Sharable Content Object Reference Model)이라는 종합적인 표준안으로 수렴하게 되면서 SCORM을 기준으로 만든 다양한 컨텐츠가 개발되고있다.

This study began with the lack of use of native Chinese professors in universities despite the fact that native Chinese professors are present and can provide a high-quality language environment to improve foreign language skills. In the literature, most team teaching studies were limited to speaking or cultural classes, and to apply a new teaching method called team teaching to Chinese grammar classes, they designed a class model and presented class guidance with an example of research 'le' In order to satisfy learners'desire for knowledge and to develop the Chinese teaching field, it is necessary to develop various teaching methods, and there should be various meaningful attempts.

The PEFP (Proton Engineering Frontier Project) is constructing a 100MeV proton Linac (Linear Accelerator). The 20 MeV 20 mA proton beam has been serviced for an application in the fields of material, biological, information technology and medical sciences. For a stable and efficient acceleration of a proton beam, the control requirements must be optimized by studying various control methods. We propose that the integrated control system for the Linac machine components must be based on a distribution control method to improve a centralized control system. Based on EPICS (Experimental Physics and Industrial Control System) real-time software, the VME (Versa Module European package format) IOC (Input Output Controller) was developed under cross development environment with a RISC (Reduced Instruction Set Computer) PowerPC system. In this paper, we describe the design and implementation of distributed control system using the VME-based EPICS middleware for various components of the large proton accelerator.

This research aims to explore the influence of early entrepreneurial education on cognitive and non-cognitive abilities of male sixth-grade primary school pupils using a randomized pretest-posttest control group design. A total of 45 students were randomly allocated to experimental, active-control, and control groups using a multi-stage random selection procedure. The experimental group was taught entrepreneurship using the Bizworld entrepreneurship education package. The active control group did not get entrepreneurship education but was instructed on a non-entrepreneurship-related issue (hygiene). The Control group received no instruction. The findings revealed that early entrepreneurial education skills impacted noncognitive abilities (such as risk-taking propensity, creativity, self-efficacy, persistence, and need for achievement). Early entrepreneurship education seems to be an effective technique for developing children's non-cognitive abilities in the late years of primary school. As a result, entrepreneurship education may be taught in primary schools, emphasizing the development of non-cognitive abilities, which will affect children's individual, educational, social, and vocational futures and can have long-term advantages for students, families, and society.

Modern OSs, including Linux, show high scalability by adopting a monolithic kernel design, but have weak security because they share all memory space. This study presents a kernel module that are isolated inside the kernel using WebAssembly. WebAssembly provides a high-performance virtual machine by defining a low-level instruction set while guaranteeing memory safety. In this paper, the WebAssembly execution environment is implemented inside the kernel, allowing developers to control the operation of kernel modules and achieving higher security.

Language Capital is one of the most important academic abilities and competencies for new era of globalization worldwide. In Europe and Asia where English is not the native language, it is necessary to encourage higher education to improve language competency from both qualitative and quantitative aspects. In so far as online university concerned, it appears of significance to prepare for globalization from the perspective of cross border education, and it needs to focus on how to design and develop English-medium teaching (EMT) or in other words English mediated instruction(EMI) for both teachers and students. In order to provide supportive programs of English-mediated class for teachers and students, the study examined and analyzed what abilities are needed for teachers based on DACUUM approach, suggesting teachers' competency as well as strategies for online- EMT. Based on literature review, DACUUM analysis, focus group interview with teachers and students who experienced online EMT, online programs supporting both teachers and students for online EMI were developed. This program expects to play roles of practical guidelines and reference for both teachers and students online in an extension of language capital improvement.

The purpose of this study was to develop a scientific inquiry model that makes scientific inquiry accessible to science teachers as well as students. To develop a scientific inquiry model, we investigated the research process demonstrated by ten scientists who were working at academic research institutions or industrial research institutions. We collected data through scientists' journal articles, lab meetings and seminars, and observation of their inquiry process. After we analyzed the scientists' inquiry strategies and processes of inquiry, we finally developed the Scientist's Methodology of Investigation Process model named SMIP. The SMIP model consists of four domains, 15 stages, and link questions, such as "if, why", and "how". The SMIP model stressed that inquiry process is a selective process rather than a linear or a circular process. Overall, these findings can have implication science educators in their attempt to design instruction to improve the scientific inquiry process.

인터넷 기반 분야가 다양화 되고 있는 가운데 교육 분야 또한 웹 활용 교육(WBI, Web Based Instruction)이 시대 흐름을 타고 그 활용도가 높아지고 있다. 인터넷을 통한 교실 중심의 획일적인 교육 분위기에서 벗어나 교육 컨텐츠 수요자 개개인의 자율성을 반영하는 것이 가능한 매체는 드물다. 교육 분야 가운데 특히 공학 교육은 해당 분야에 관한 특수성과 전문성이 요구되어 수요자 중심의 효과적인 교육 컨텐츠 개발에 어려운 요소로 작동한다. 이렇듯 유연한 매체를 이용함에 있어서 게슈탈트 시지각 이론을 적용함으로써 좀더 효과적인 WBI 활용을 유도하는 것은 자원 이용율 측면 및 학업성취도를 높이는데 기여할 수 있겠다. 이에 본 논문에서는 공학 교육을 위한 게슈탈트 시지각 이론 기반 WBI 시스템을 설계하고자 한다.

현재 학교에서 이루어지고 있는 수업의 문제점 중의 하나는 교수자가 학습자의 이해 및 요구사항을 정확히 파악하지 못한 채 일반적인 강의형식으로 수업이 진행된다는 것이다. 학습자들은 면대면에서 오는 두려움으로 인하여 적극적으로 수업에 참여하지 못하고 이로 인하여 교수자는 학습자들의 이해와 생각을 파악하지 못한 채 단순 지식전달 형태의 수업이 진행되며, 이로 인하여 학습자는 학습목표 달성에 어려움을 겪는 악순환이 발생되고 있는 것이다. 이에 본 연구에서는 단순하면서도 효과적으로 학생들의 수업참여를 유도할 수 있도록 하고 교수자가 학습자의 생각과 의견을 한눈에 파악할 수 있는 기능을 기본으로 하는 수업 보조도구를 설계 및 구현하였다. 양질의 솔루션을 제공하고 추후 확장성 및 시스템의 활성화를 고려하여.Net Framework2.0 기반으로 개발 하였다.

Retargetable compiler which generates executable code for a target processor and performance profiler are required to design a processor optimized for a specific application. This paper presents an architecture exploration methodology based on ADL (Architecture Description Language). We synthesized instruction set and optimized processor structure using information extracted from application program. The information of operation sequences executed frequently and register usage are used for processor optimization. Architecture exploration has been performed for JPEG encoder to show the effectiveness of the system. The ASIP designed using the proposed method shows 1.97 times better performance.
