This Paper Presents an Internet-based Java self-learning educational system which consists of a management system named Java Web Player (JWP) and creative multimedia contents fer Java language. The JWP Is a Java application program free from security problems by the Java Web Start technologies that supports an Integrated learning environment including three Important learning Procedures: Java concept learning Process, Programming practice process and assessment process. This JWP enables the learners to achieve efficient and Interesting self-learning since the learning process is designed to enhance the multimedia capabilities on the basis of various educational technologies. On-line voice presentation and its related texts together with moving images are synchronized for efficiently conveying creative contents to learners. Furthermore, a simple and useful compiler is included in the JWP fur providing user-friendly language practice environment enabling such as coding, editing, executing and debugging Java source files on the Web. The assessment process with various items helps the learners not only to increase their academic capability but also to appreciate their current degree of understanding. Finally, simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box. The proposed system can be used for an efficient tool for learning system on the Web.

Detecting web attacks is a major challenge, and it is observed that the use of simple models leads to low sensitivity or high false positive problems. In this study, we aim to develop a robust two-stage deep learning based stacked ensemble web application firewall. Normal and abnormal classification is carried out in the first stage of the proposed WAF model. The classification process of the types of abnormal traffics is postponed to the second stage and carried out using an integrated stacked ensemble model. By this way, clients' requests can be served without time delay, and attack types can be detected with high sensitivity. In addition to the high accuracy of the proposed model, by using the statistical similarity and diversity analyses in the study, high generalization for the ensemble model is achieved. Within the study, a comprehensive, up-to-date, and robust multi-class web anomaly dataset named GAZI-HTTP is created in accordance with the real-world situations. The performance of the proposed WAF model is compared to state-of-the-art deep learning models and previous studies using the benchmark dataset. The proposed two-stage model achieved multi-class detection rates of 97.43% and 94.77% for GAZI-HTTP and ECML-PKDD, respectively.

웹 기반 교육은 시간적, 공간적으로 분산되어져 있는 학습자들이 웹을 통해 학습이 이루어지는 형태로써 전통적인 학습 환경과 달리, 학습자의 적극적인 참여의지가 필요하다. 여기에서 참여의지는 학습동기의 중요한 한 측면으로 볼 수 있다. 그러나 기존의 웹 기반 수업 설계는, 학습자의 인지적인 측면만을 고려하는 것이 대부분이다. 따라서 본 연구에서는 학습자의 학습동기를 촉진하기 위한 '감성게시판'의 설계 전략을 제시하고자 한다.

웹 기술의 빠른 성장과 더불어, 웹은 다양한 측면에서 우리의 삶뿐만 아니라 교육과 학습을 변화시켰다. 웹 기반 학습은 자기 주도적 학습과 창의적 학습을 언제 어디서나 지원해 줄 수 있게 되었지만 학습 내용들로 구성되는 하이퍼 공간의 구조가 복잡할 경우 학습자들은 방향 감각 상실이나 인지 과부하를 경험할 수도 있다. 본 논문에서는 인지적 부하 이론을 근거로 초보자들이 프로그래밍 학습을 한 때 경험할 수 있는 인지 부하를 줄일 수 있는 웹 기반 적응형 하이퍼미디어 시스템을 설계하고 구현하였다.

현재 교육현장 일선의 교사들은 교과 수업준비를 위해서 많은 시간과 노력을 기하고 있다. 특히 미술 교과수업의 기초 조형수업은 다양한 준비물(석고 모형 등)과 조명시설 준비를 통하여 학습이 이루어져야 교육적 효과를 높일 수 있으나 현실은 여러 여건상 그렇지 못하다. 제안된 웹 학습도구는 이러한 준비물과 조명 조작 도구를 웹 환경에 탑재하여 간단한 조작만으로 기초 조형수업이 가능하도록 제작하였다. 본 논문은 기초 조형수업을 개선하기 위한 웹 학습도구를 제안하였다. 이러한 웹 학습도구를 사용한 기초 조형수업은 학생들이 표현하기 어려웠던 조명에 의한 물체의 음영 표현과 그림자 표현 등의 교육적 효과에 기여 할 것이다.

Purpose: Level of reflective thinking of students are important factors in the area of nursing studies on web-based PBL. These factors were used as a component of learning strategies. One was to understand general recognition to web-based PBL and reaction to the use of reflective journal. The other was to investigate the level of reflective thinking was related to learning activity. Method: PBL was adopted for an online course titled 'Nursing Assessment and Intervention'. Twenty graduate students were evaluated from questionnaire, reflective journals, and individual assignments. Result: Web-based PBL was strong for self-directed learning, team activity, creative thinking, diversity of thinking, and diverse process of learning while hard time, lack of cooperation, uncertainty of outcome, and lack of time were considered as weakness. Reflective journal gave moderate help to learning activities. The learners' learning activities was the lowest in the middle level of reflective thinking. Conclusion: Generally, graduate students in college of nursing showed slightly positive attitude to PBL experience and slightly positive reaction to the learning effect of reflective journal. PBL was estimated to be valuable and meaningful. There was no relationship between the level of reflective thinking and learning activities.

본 연구는 중학생들의 달의 운동 개념 지도에 적합한 웹 기반 프로젝트 학습을 설계하고 이를 수업에 적용하여 그 효과를 알아보는데 목적이 있다. 중학교 3학년 학생 48명을 연구 대상자로 하였고, 그 중 남 녀 각 5명씩 10명을 면담을 이용한 연구 대상자로 하였다. 본 연구에서 개발한 개념 수준 질문지와 면담을 이용한 사전 검사를 실시하여 달의 운동에 대한 비과학적 개념의 유형과 원인을 분석하였다. 사전 검사 후, 달의 모양을 관찰하고 관찰 결과에 대해 서로 토론을 하는 웹 기반 프로젝트 학습을 약 한 달 동안 실시 하였다. 프로젝트 학습을 종료한 후 사후 검사를 하였고 사전 검사와 비교하여 학습 효과를 알아보았다. 그 결과, 웹 기반 프로젝트 학습이 달의 운동에 대한 개념 변화에 효과적인 것으로 나타났다(P<001). 또한 과학 탐구능력에서도 유의미한 차이를 보였다. 과학 탐구능력 요소 중에서 특히, 실험 설계(P<001)와 변인 찾기 및 조작적 정의(P<.05)영역에서 유의미한 차이가 있었다.

Purpose: This study was done to compare the effectiveness of web learning versus traditional education for learning Asepsis technique in Basic Nursing Practice. Method: This research was a quasi-experimental study. The participants were 60 students who were taking Basic Nursing at a nursing college in G city. Thirty students each were assigned to the experimental and the control group. Data were collected between September 26 and 30, 2005, The data were analyzed using descriptive statistics, Independent t-test and ANCOVA Results: The mean score for competence in Asepsis technique practice in the experimental group was 24.73 and in the control group 22.80. This result was statistically significant(t = 3.723, P = .001). The mean score for knowledge in the experimental group was 42.93 and in the control group 38.93. This result was statistically significant(t = 2.119, P = .038). The mean score for satisfaction with degree of study in the experimental group was 55.50 for the pre-test and 56.17 for the post-test, and in the control group 60.23 and 58.00 respectively. This result was statistically significant(F = 10.537, P = .002). Conclusion: The Web based learning was found to be effective in nursing practice, student satisfaction and knowledge, but web-based programs have to be continuously managed and various demands from learners have to be accepted. Eventually we have to use web-based program as educational medium to promote effective learning nursing education.
