소프트웨어 교육의 관심이 커짐에 따라 교육부에서 필수로 초등 5~6학년 실과에 소프트웨어 교육을 진행하도록 하였다. 이 연구에서는 학습자 중심 평가를 소프트웨어 교육에 적용하여 그 효과성을 분석하였다. 이를 통해 많은 교사가 학교 현장에서 소프트웨어 교육에 학습자 중심 평가를 적용하여 좀 더 효과적인 소프트웨어 교육이 되었으면 한다. 학습자 중심 평가에서는 학생들이 능동적으로 수업에 참여하고 적극적인 학습 활동을 함으로써 긍정적인 효과를 기대할 수 있다. 학습자 중심 평가를 통해 여러 배경 변수를 고려하여 학생들의 3가지 측면, 창의력, 문제해결력, 정보 활용 능력이 어떻게 변화하는지 확인하고, 소프트웨어 교육에서 학습자 중심 평가가 이 능력들에 어떠한 영향을 미치는지 확인하였다. 연구 결과, 소프트웨어 교육에서 학습자 중심 평가가 창의력, 문제해결력, 정보 활용 능력에 모두 유의미한 효과가 있었고 엔트리/스크래치 공부 경험의 유무 또한 이에 영향을 주었다는 것을 확인할 수 있었다.

In education, innovative ways of teaching and learning are always under development and keep being proposed with advanced concepts since the ancient times. Student-centered learning, problem-based learning and cooperative learning have been three major trends under development in secondary education research and practice more than a decade or so. Combined with advanced information and communication technologies, these trends will greatly transform the way we teach and learn in classroom environment and may change the classroom environment itself, into a more interactive and self-centered coaching type environment. In this study, a smart environment that utilizes advanced information technology devices and network is conceptualized, accommodating requirements contained and proposed in the recent trendy pedagogies. Pedagogical cases discussed in these trends are analyzed in detail, producing requirements for such a learning and coaching environment. These requirements are modeled using unified modeling language, leading to a proposal of a basic architecture for an information system supporting this environment.

Backround : The paradigm of recent education has been shifting from existing style of professor-oriented, passive and rote teaching to learner-centered education. Rather than mere delivery of knowledge, today's idea of education uses various audiovisual media to let learners gain more problem-solving skills, judgment, cognitive thinking ability, and creativity to apply to real practice. Also, while current trends and change in policy ask for related industry to require practice-centered teaching learning model, Problem-Based Learning (PBL) is quite effective that it activates problem-solving skills as well as application of National Competency Standards (NCS). Purpose : The purpose of this study was to suggest a teaching learning model article as an approach to apply web-based PBL for patient & medical charge management practices. Discussion & Conclusion : This paper the cases on PBL and presents the teaching learning model on web-based PBL as an approach to applying web-based PBL, which fits Medical Information System Department that combines health-medical treatment and computer applications, to practical health administrative affairs.

학습자가 학습을 시작하기 전 혹은 학습을 진행하는 동안 전문가의 정신모형을 제시하는 모형 중심 교수는 비전문 학습자의 문제해결 과정에 도움을 줄뿐만 아니라 학습의 과정을 용이하게 할 수 있다. 또한 협동학습 전략은 모형 중심 교수 이론을 적용하는 인지 도제 학습 모형의 여섯 단계 동안 비전문 학습자의 정신 모형을 정교하게 하고 반추하도록 하는데 큰 역할을 할 수 있다. 본 연구는 '컴퓨터교육'교과를 수강하는 교육대학교의 예비교사들의 교수설계 과정을 학습하는데 있어서 모형 중심 교수와 협동학습의 효과를 탐구하여 그 결과를 제시하였다.

정보통신기술의 발달로 교육환경에서도 많은 변화가 일어나 ICT 활용 교육을 통한 다양한 형태의 교수 학습 유형이 논의되고 있으며 최근에 급격히 발달하고 있는 인터넷을 활용한 원격교육이 급격히 확산되고 있는 실정이다. 하지만 교사가 일방적으로 과제를 제시하고 학생들은 인터넷 사이트를 활용하여 정보를 수집하여 가공하는 보여주기식에 그쳐 학생간 교사간의 상호작용이 부족하여 인터넷 활용 학습의 장점을 살리지 못하고 있다. 이에 본 연구에서는 웹과의 통합적 또는 보완적 차원에서 가장 적합하다고 여겨지는 구성주의의 문제중 심학습 이론을 기반으로 하여 화상통신기술을 활용한 문제중심학습 환경을 구현하고 초등학교 현장에 적용하여 그 결과를 분석하였다. 그 결과 교사와 학습자간 학습자 동료 집단간의 상호작용에 효과가 있었으며 학습자의 수업에 대한 참여 태도 및 흥미, 집중력에 긍정적인 효과를 가져왔다. 또한 면대면 학습에서 부족했던 부분을 사이버 학습을 통해 보완할 수 있었으며 문제중심 학습모형의 장점을 살릴 수 있었다.

The SW-centered battlefield management information system R&D project takes a long period of 5-10 years or more by applying a complex and rigid batch acquisition strategy. In order to solve this problem, it is necessary to institutionalize a rapid and flexible battlefield management information system R&D project management procedure applying agile development methodology, and a government project management organization and contract management method to support it In this study, we analyzed the case of applying the Agile development method centered on Scrum to the US SW-centered weapon system R&D project and the characteristics and problems of the battlefield management information system R&D project in Korea, and suggested improvement measures as follows. First, the battlefield management information system R&D model applies the hybrid development method, and the system requirements analysis and system structure design use the existing waterfall development procedure, and the agile method is applied from the SW requirements analysis to the system integration stage. Second, flexible adjustment of performance, schedule, and cost by organizing an Agile IPT in which military (requirements) - DAPA (project management) - developer - functional specialized organizations (test and evaluation, quality, government research institutes, etc.) participate. Third, improving the Basic Order Agreement so that it can be applied to agile R&D.

In the 4th Industrial Revolution, the healthcare industry is undergoing a paradigm shift from post-care and management systems based on diagnosis and treatment to disease prevention and management based on personal precision medicine. To optimize medical services for individual patients, an open ecosystem for the healthcare industry that allows the exchange and utilization of personal health records (PHRs) is required. However, under the current system of hospital-centered data management, it is difficult to implement the linking and sharing of PHRs in practice. To address this problem, in this study, we present the design and implementation of a patient-centered PHR platform using blockchain technology. This platform achieved transparency and reliability in information management by eliminating the risk of leakage and tampering/altering personal information, which could occur when using a PHR. In addition, the patient-consent system was applied to a PHR; thus, the patient acted as the user with ownership. The proposed blockchain-based PHR platform enables the integration of personal medical information with scattered distribution across multiple hospitals, and allows patients to freely use their health records in their daily lives and emergencies. The proposed platform is expected to serve as a stepping stone for patient-centered healthcare data management and utilization.

The purpose of this study is to orient users' touchpoints in co-design experience, to identify their need via visualized experience map, to recommend valid design information in online e-customization services. A user-centered co-design experience map (UCEM) is adopted to analyze the relation between users' desire and time spent, so as to evaluate the online co-design experiences. Based on evolutionary algorithm and fuzzy theory, data of this study is collected from 30 participants. The data was analyzed by descriptive analysis in SPSS, and frequency query and word cloud in NVivo. Employing design category and evaluating users' time spent, the findings are that (a) vamp color matching is consistent with interview data; (b) supported by qualitative feedback, the virtual experience map played an important role in the co-design process and the visualized interaction process; and (c) participants prefer to get more information and professional help on color matching and exterior design. Based on the findings in design category, future work should be focused on developing a better understanding of design resource recommendations and multi-stakeholder communication.

In this paper, we consider a generalized Riemann problem of the first order hyperbolic conservation laws. For the case that excludes the centered wave, we prove that the generalized Riemann problem admits a unique piecewise smooth solution u = u(t, x), and this solution has a structure similar to the similarity solution u = $U{(\frac{x}{t})}$ of the correspondin Riemann problem in the neighborhood of the origin provided that the coefficients of the system and the initial conditions are sufficiently smooth.

Flow mechanism of contractive and dilative motion is numerically investigated to obtain a propulsive force in highly viscous fluid. An axisymmetric code is developed with unstructured grid system based on cell-centered scheme. It is validated by comparing with the results of Stokes approximation for the problem of uniform flow past a sphere in low Reynolds number(R$_{n}$=1). The validated code is applied to the simulation of contractive and dilative periodic motion of body whose results are quantitatively compared with the two dimensional case. In order to investigate the grid dependency, two different grids are applied to the present computations. The present study provides key information for the development of an axisymmetric Micro-hydro-robot.t.
