In a small-scale class, children gradually lose interests in studying and develop negative and passive attitudes in class activities due to the uniform education. Although many cooperative instruction WBI models are studied and designed, there has not been any research on cooperative instruction model appropriate for a small-scale class. In this study, instructors participate in classes, each in connection with other small-scale classes, and WWW based cooperative instruction model, WIEZ, which can affect students' learning attitude on long-term basis, was designed and embodied. Currently, WIEZ is being under experimental test in three schools at Kyung-nam where instructors design classes, and students divided into groups participate in classes in this system.

This paper describes the web-based collaborative learning system, in which the constructivism is used as a background theory. We designed and developed three modules (Learner Module, Instructor Module, Administrative Module) to promote the interactive communication between learners and instructors and to enable the self-directed collaborative learning. In addition, the assignment and evaluation sessions are closely linked with each other to ensure the high quality of the system. We expect this research helps to construct the efficient collaborative learning environment using the ICT(Information & Communication Technology).

One of the cooperative learning models, the cooperative learning of structural approach which is very simple and easily applicable accomplishes teaching-learning through combining learning contents and organic connections of various structures. This work proposes a cooperative teaching-learning model for the structural approach, designs and implements a web-based cooperative system supporting it. The model provides a concrete frame which can apply to a subject learning thus could effectively support cooperative learning. Furthermore, it classifies learning into three types such as knowledge learning, investigation, and function mastering and presents a structure application model for each so as to apply different structures according to learning materials and types. We implemented a system that performs cooperative learning on the basis of these models, applied to a class, and analyzed the effect of it.

가상교육에 대한 초등학교 아동들의 교육적 욕구가 증대되고 있는 상황에서 현재까지는 웹기반의 학습내용 게시 및 문제제출 등에 연구들이 많이 진행되어 왔다. 또한 현 교육과정에서 강조되고 있는 협동학습에 대해서도 이론적인 연구들이 많이 발표되었으나, 이를 학교 현장에서 실제적으로 협동학습 프로그램을 개발하여 운영하는 학교들은 거의 없다. 본 연구에서는 웹 기반의 학급 경영모델을 기본 환경으로 구축한 후, 이러한 학급경영모델에 협동학습을 지원할 수 있는 세부 내용을 설계하고 구현하였다. 현재 초등학교 1개 반을 대상으로 구현된 모델에 따라 학급을 운영하면서 학습현장의 문제점에 대해서도 고찰한다.

The social interest for collaborative learning and educational game has been increased. In this paper, we investigates the educational value of collaborative learning and game. Based on this investigation, we propose an educational on-line game model for collaborative learning. Although the proposed model is still conceptual design, it sufficiently shows that on-line RPG game can be a good collaborative learning method for young children. In detail, we speculate about the conventional educational method performed in normal school. And then, we describes the elements of a computer game which complies with the real collaborative learning program.

This paper describes an approach to collaborative design which focuses on the effects of individual activities on the overall design process. We utilize a new process modeling tool to define the process and then analyze and refine the process based on critical paths. This information is then shared over the Internet with all participants. The goal of this system is to detect critical errors at initial design stage and guide the designers to make better decisions based on the knowledge of the overall process. This system enables participating designers to publish his local process through an Internet bulletin board. Other members of the team can then provide feedback based on how the proposed process impacts their activities. The system provides a context-rich, persistent forum for collecting, preserving, and refining corporate expertise of the team. For example, designers can select any process from the bulletin board and use it as a template for his current project and then use it to maintain his own design history. This paper is based on the process modeling concepts of Design Roadamap and describe several key extensions in the area of CPM calculations and collaborative interfaces.

본 연구에서는 민감한 개인정보의 유출과 남용 위험이 높아지고 있는 상황에서 정확한 개인정보 탐지 및 비식별화의 효율을 높이기 위해 개인정보 항목에 특화된 개체명 체계를 개발하였다. 개인정보 태그셋이 주석된 대화 데이터 4,981세트를 구축하고, 생성 AI 모델을 활용하여 개인정보 개체명 탐지 실험을 수행하였다. 실험을 위해 최적의 프롬프트를 설계하여 퓨샷러닝(few-shot learning)을 통해 탐지 결과를 평가하였다. 구축한 데이터셋과 영어 기반의 개인정보 주석 데이터셋을 비교 분석한 결과 고유식별번호 항목에 대해 본 연구에서 구축한 데이터셋에서 더 높은 탐지 성능이 나타났으며, 이를 통해 데이터셋의 필요성과 우수성을 입증하였다.

현재 중. 소형조선소의 소헝선박설계는 실무자의 경험에 의해 설계가 이루어지고 있다. 이러한 이유로 지금까지 소형선박설계는 정보의 생성과 교환 및 축적이 원활하지 못해 많은 문제점을 가지고 있다. 본 연구에서는 소형선박설계의 정보 공유와 협동설계를 위한 방법으로 최근 인터넷의 발달로 인한 분산환경에서의 동시공학개념의 접근방법을 제시하였다. 이를 위해 소형선박의 초기설계에서 기본정보의 생성을 위한 주요치수선정 프로그램을 개발하고 생성된 정보의 공유를 위해 에이전트기반 시스템개념을 적용하고자 하였다. 특히 제어에이전트의 주요기능인 Content-Based Routing 개념을 제시함으로 에이전트를 기반으로 한 설계시스템의 통합화를 보이고자 한다.
