  • 최근에 웹을 이용한 원격교육에 대한 않은 학습 방법들이 제시되고 있으며, 단순히 학습만을 고려한 방법부터 실시간으로 원격시험을 치르는 방법까지 다양하다 웹 기반의 학습에서 많이 적용되는 방법이 문제를 통한 학습이며, 기존의 학습들은 학습자가 개인 수준에 안는 문제 난이도를 직접 선택하거나, 문제를 동적으로 추출하여 학습하는 방식이다. 그러나 이 방법들은 단순히 출제되는 문제 자체의 차별성을 기반으로 하므로 학습자의 능력별 학습이 이루어지기 어려운 문제점이 있다. 본 논문에서는 이러한 문제점을 해결하기 위하여, 개인의 문제유형별 약점정보를 기반으로 유형별 추출되는 문제에 난이도를 두어 개인별 학습 능력을 정확히 평가한다. 그리고 다음 단계의 학습에서 개인별 학습정보를 충분히 반영하여 문제들을 출제하므로 학습자의 학습효과를 높일 수 있다. 따라서 이 시스템은 문제유형과 문제난이도에 대한 개인의 정보를 반복적으로 적용하여 학습할 수 있으므로, 더욱 효과적인 원격학습을 제공할 수 있다.

  • The objective of this study is to identify the visual function impairment of children with each type of attention deficit hyperactivity disorder(ADHD). The subjects of this study were 49 children diagnosed with ADHD with visual function out of the normal range. The type of ADHD was investigated using the Korean-ADHD Rating Scale and visual function test. The attention deficit type(69.4%) of ADHD was the most common type among children with ADHD with vision problems. Although their overall naked-eye visual acuity was good, about 50% of the subjects showed problems with visual function. For those with the attention deficit type of ADHD, the myopia-related refractive error was high. For those with the hyperactivity type of ADHD, the astigmatism-related refractive error was higher. For those with vergence function disorder, convergence insufficiency was the most common. As there were differences in the visual impairment characteristics of children with different types of ADHD, it is necessary to approach a child's problem behavior through examination and screening for visual function disorders.

  • The traffic in research network for the new structure of the network and new service research has the various properties. From the perspective of a specific traffic point of view, transmission of traffic with different requirements using a single routing protocol is an obstacle to satisfy requirements. In this study, we classify the properties of the traffic into two types. We propose the way that we can get the overall optimization effect, the experiment proves it by providing independent multiple forwarding path by applying optimized algorithm by types. In order to distinguish each type of traffic we use the ports on the switch and in order to implement independent path we apply OpenFlow system. In other words, we present the measure that can be implemented to improve the satisfaction of the traffic by making multiple paths by OpenFlow controller according to the type of traffic and by enforcing in Forwarder.

  • EJB의 애플리케이션 개발환경은 객체지향 분산처리를 지원하는 컴포넌트를 개발하고 분산 배치를 위한 컴포넌트 구조이다. EJB를 이용하여 개발한 애플리케이션은 컴포넌트 모델의 개념을 결합하여 비즈니스 프로그램의 개발이 쉽도록 단순화시켰으며, 보안성, 리소스 풀링, 영구성, 동시성, 트랜잭션 무결성을 자동적으로 해결해 준다. 본 논문에서는 이러한 개발환경에서 EJB 컴포넌트가 충분한 유연성을 가질 수 있도록 기능별로 효율적인 빈의 유형을 추출하는 방법을 찾고자 하였으며, EJB 빈의 유형별 특성에 따라서 빈 유형을 쉽게 분류할 수 있는 방법을 표준화하여 시스템 분석 및 설계시 반영할 수 있도록 하였다. 본 논문의 제안모델은 단계별로 전 단계의 모델을 재사용하고, 객체를 쉽게 빈으로 매핑할 수 있도록 표현계층, 비즈니스 로직계층, 데이터계층으로 계층화하여 객체를 배치함으로써 빈의 유형을 쉽게 추출할 수 있는 방법을 제공한다.

  • Along with the increased significance of SW education in the 2015 revision curriculum, SW education using various educational methods and tools is being performed, and teaching and learning contents using SW education tools are continuously being developed. In this paper, we analyzed pre-service teachers' EPL contents preference types, preferred development subjects, and their relationship with pre-service teachers based on the analysis conducted after their EPL class session in which its results were assortatively analyzed by department, letter grade, and type. The result signified a clear difference in development subject and types among the departments, and it also showed a difference in development subject and its recipients among the types. However, there was no difference between development subject and type among the letter grade. This will provide a feedback on EPL classes and help develop EPL-related curricula as well as its application.

  • This study has intended to develop an evaluation model to select suitable locations of recreation forests in accordance with their types, and to apply the models to the feasibility study of selecting suitable recreation forest locations of candidate sites. To reach this goal, this study employed a Delphi expert survey method and Analytic Hierarchy Process (AHP) for the whole process of model building. And the followings are what this study has found during model building and application process. First, the assessment criteria for classifying recreation forests and selecting suitable locations were initially identified through justification process with two rounds of expert review, after broken down into 2 categories, and then further divided into 6 items and 12 indicators accompanying with hierarchical structure. Second, in the third phase of Delphi expert survey, the relative weights of the assessment criteria were derived by employing AHP. Through overlaying two evaluation categories including resource and usability, 4 types of recreation forest were presented. In the forth phase of the Delphi survey, this study has developed an evaluation model to select suitable locations of recreation forests in accordance with their types using relative weights of the selected indicators through. This study has applied the models to the feasibility study of selecting suitable recreation forest locations of candidate sites, and found that the usability of recreation forest was severely affected by the distance from the capital region, that the closer the locations of natural recreation forests from the capital region, the more advantageous. The developed model can be used to designate recreation forests in accordance with their types.
