When developing a weapon system, a T&E(Test and Evaluation) can be performed using M&S for the test items that cannot be evaluated in the real world. In this case, the VV&A activities are required to prove the credibility of M&S for the T&E. Recently, the use of M&S has been increasing as the R&D trends of weapon systems are becoming more advanced. Therefore, the VV&A activities are also increasing. The VV&A activities aim to verify, validate, and accredit that the simulation can represent a real system and ensure credibility regarding its purpose and intention of use. VV&A activities are divided into V&V and Accreditation. When performing VV&A in the ADD (Agency for Defense Development), the V&V activities are performed by a separate department of the ADD and the accreditation activities are performed in the DTAQ (Defense Agency for Technology and Quality). This paper proposes a V&V process for a T&E of M&S that has been performed in ADD. The process is used to verify and validate the documents and data generated during the development process according to the accreditation criteria, and provides objective data that can be used to judge whether the accreditation decision and acceptance criteria are met.

학술 연구 활동에 있어서 관련 정보의 수집은 중요한 연구 활동 중의 하나이다. 특히 첨단 과학기술 분야의 연구에 있어서 최신의 학술 잡지에 게재된 논문에 대한 정보들은 더욱 중요성을 같는다. 본 논문에서는 한국과학기술원에서 교수, 학생, 연구원에게 학술 잡지 정보를 신속하고 편리하게 제공하기 위해 개발된 학술 잡지 목차 서비스 시스템 (Journal Current Contents Service System, JContents)을 소개하기로 한다. JContents 시스템은 클라이언트/서버 구조를 바탕으로 GUI(Graphic User Interface) 환경을 제공한다. 특히 캠퍼스 정보 시스템과 연계하여 사용자가 원하는 정보를 E-Mail을 통해서 도서관에서 자료 입수 즉시 사용자에게 보낼 수 있도록 하여, 학술 정보를 신속하고 편리하게 제공함으로써 연구 생산성을 높이는데 기여한다.

In this study, an e-portfolio system was constructed and utilized to communicate with students, while processing the overall procedure of teaching-learning activities as data for qualitative improvement in the non-face-to-face educational environment. The e-portfolio system was designed to support the entire process of reflection from the instructor's lesson planning, regular checking of the learner's understanding during the course operation process, online communication, and support for learner-centered educational activities. Analyzing the effectiveness of the communication-based learning effect between instructors and learners using the e-portfolio in liberal arts programming classes, which may be difficult for non-major students, a significant correlation was found in problem-solving skills, and midterm and final exams. Additionally, the result of analyzing the expanded applicability of e-portfolio satisfaction demonstrated a significant correlation with the students' computational thinking ability, test results, assignments, and academic performance. It was found to have a significant effect on the improvement of computational thinking ability. If non-face-to-face education is conducted using the proposed e-portfolio system type, it will be possible to improve the quality of online education, while communicating effectively with students.

In this paper, we propose u-learning hub site systems which are designed and implemented based on learning activities oriented components. The proposed systems are composed of component which can process the functionalities for coming into action of learning activities through various devices. Specially, each component is broken into class units by which learning activities of users can be performed on various devices. When users try to connect u-learning system in hub site, the system explores devices of users and connection program and then selects components that are fit to the activities and combines them in realtime. Through the methodology of u-learning hub site, the system proposed in this paper provides u-learning environment so that users can use the learning activity services taking no influence on time, place, devices and programs under the consistent system. That is different to traditional e-learning system which cannot support various devices of users directly.

Since B2C(Business to Customer) from which e-commerce had originated was replaced by B2B, e-Business has shown fast growth so fa., Recently, e-Procurement by l:n concept is on the development as self-purchase system associated with their own ERP In many conglomerates in the Korean market. However, in order to vitalize e-Biz in the plant industry, we need to set up e-marketplaces where many sellers and buyers can meet each other at the same time, which has become the essential part for success as an expanded business model. In this paper, we expect that the foundation for e-transformation in the plant industry is set up by developing Purchase Process System and related modules as the prerequisite for e-Biz in the plant industry, and this report will provide an exemplary model for e-commerce. The Purchase Process System consists of 1) e-Purchasing Module that manages bidding and contract information based on quotation inquiry, 2) e-Expediting Module that manages information to guarantee the on-time delivery, 3) e-Certification Module that controls user authentification, 4) e-Basic Module that manages the bulletin boards, Q&A, etc.

In recent years, e-portfolios and webfolios have been highly vaunted as the next great innovation in education. Hundreds of academic institutions are variously studying, using, or innovating e-portfolio systems. Despite the presumed goodness of e-portfolios, some problems remain. In this paper we review the existing e-portfolio management systems, and propose and implement a novel system to overcome the limits of the existing e-portfolio management systems. The propose e-portfolio management system has a structure of competition with others. All of the student's activities are accomplished and preserved within the same personal web space like a blog with mutual engagements and recommendations.
