Research on ways to improve e-learning effectiveness has been actively conducted due to the increased numbers of web-based e-learning learners. Of many variables related to e-learning effectiveness, self-regulated learning strategy and presence have been reported as major factors that influences academic achievement in e-learning settings. The purpose of this study was to investigate the effect of self-regulated learning strategy and presence on academic achievement in web-based e-learning. In addition, this study tried to provide useful basic data for successful support and design of e-learning by verifying the mediating effect of these variables. As a result, it was verified that teaching presence and social presence have mediating effects in the relationship between self-regulated learning strategy and perceived achievement in web-based e-learning. Moreover, subjective perception of student's academic achievement played a mediating role between learners' perceived presence and academic achievement. Through this study, it is verified that it is necessary to search for ways to improve the level of learners' teaching presence and social presence in web-based e-learning design in order to eventually improve academic achievement.

We developed a Web courseware using multimedia based on STS(Science-Technology-Society) and constructivism on fossil of fourth grade natural science in Primary school, which is recognized to be hard to simulate and watch the phenomena in real life. At present, there are several researches manifesting the effectiveness of the theory with off-line instructional materials. However, there are few results which demonstrate its ability on the Web. The main objective of the paper is to apply the STS theory on a Web courseware and to observe its efficacy. The Web courseware based on the theory allows students to observe and experiment in the Web environment and to have diverse experiences and thoughts through communication via Web. The paper shows that Web courseware based on STS theory can improve its effectiveness in a collaborative learning environment by providing Web facilities such as E-mail, Web search, information sharing, chatting, and so on.

The proximity web 2.0 has in our daily life changes in the way we educate ourselves occur naturally. New generations of learners naturally study and utilize web 2.0 as part of general life, so they require an education method which considers this characteristic. One such method, WIKI Based Cooperation Learning has recently been studied. The object of this study is to establish any relationship between learners attitude and academic achievements when implementing WIKI Based Cooperation Learning in the subject of social studies.

Development and Evaluation of the Effectiveness of a Web-Based Learning System Program for Nursing Education on Peritoneal Dialysis Ji-Soo Yoo(Professor, College of Nursing, Yonsei University, Seoul, Korea) Seong-Mi Moon(Doctoral Candidate, College of Nursing, Yonsei University, Seoul, Korea) The purpose of this study was to develop a nursing education program using a web-based learning system to teach peritoneal dialysis and to evaluate the effectiveness of the program. The program was developed in two steps. The first step was to develop the content using CVI, and the second was to program it using HTML. The program which was developed was evaluated with 50 nurses of whom 48 responded to the questionnaire. The results are as follows: Of the subjects, 85.4% responded that they were satisfied with this web-based learning system and 87.5% stated that they would recommend this system to nurses who are in other nursing education programs. Of the educational material charac- teristics, the item that the subjects evaluated as most valuable was "accuracy of the content". For system related charact- eristics, the item to which the subjects gave the most positive response was "clarity of the system tool marking" (81.3%). In conclusion, it was verified that a web-based learning system is an effective and satisfactory method for nursing education.

This paper presents an investigation on the shear resistance of corrugated web steel beams (CWBs) with a circular web opening. A total of five specimens with different diameters of web openings were designed and tested with vertical load applied on the top flange at mid-span. The ultimate strengths, failure modes, and load versus middle displacement curves were obtained from the tests. Following the tests, numerical models of the CWBs were developed and validated against the test results. The influence of the web plate thickness, steel grade, opening diameter, and location on the shear strength of the CWBs was extensively investigated. An XGBoost machine learning model for shear resistance prediction was trained based on 256 CWB samples. The XGBoost model with optimal hyperparameters showed excellent accuracy and exceeded the accuracy of the available design equations. The effects of geometric parameters and material properties on the shear resistance were evaluated using the SHAP method.

We now live in a society that is highly information-oriented, and as a result programming education has become more important and is emphasized day by day. Currently, there is strong support for carrying out programming education in early childhood, and various Web-based services have launched to provide programming education. Currently, Web-based programming education services have not yet launched in Korea. In particular, Web-based education services for C language programming, which is used in various areas in industry, are lacking due to limitations in the development environments. In this paper, we design and implement a Web-based programming learning system, 'ICANC', to provide the necessary information to learn and practice the C language.

The appearnace of web technology has accelerated the development of the multimedia technology, the computer communication technology and the multimedia application contents. Researches on WBI(Web-based Instruction) system have combined the technology of the digital library and LOD,. REcently WBI(Web-based Instruction) model which is based on web has been proposed in the part of the new activity model of teaching-learning. As the demand of the customized coursewares from the lwarners is increased, the needs of the efficient and automated education agents in the web-based instruction are recognized. In this paper we propose a system monitors learner's behaviors constantly, evaluates them, and calculates his accomplishment. And the system offers suitable course to learner applying this accomplishment degree to agent's schedules. Therefore, the learner achieves an active and complete learning from the repeated and suitable course semantic-based retrieval.

This study investigates the causal relationships among flow experience, self-directed learning readiness, internet addiction and academic achievement in web-based computer education. The gender differences in path models were also examined. The results indicated that, self-directed learning readiness has positive and direct influence on flow experience and academic achievement. And self-directed learning readiness has a negative and direct influence on internet addiction. For female students, academic achievement was positively and directly influenced by flow experience and indirectly by self-directed learning readiness. However, the mediating effect of flow experience and indirect effect of self-directed learning readiness were not significant for male students.

This paper presents an internet-based self-learning educational system which can be enhancing efficiency in the learning process of Java language. The proposed self-learning educational system is called Java Web Player(JWP), which is a Java application program and is executable through Java Web Start technologies. In this paper, three important sequential learning processes : concept learning process, programming practice process and assessment process are integrated in the proposed JWP using Java Web Start technologies. 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 educational technologies. Also, online voice presentation and its related texts together with moving images are synchronized for efficient language learning process. Furthermore, a simple/useful compiler is included in the JWP for providing language practice environment such as coding, editing, executing and debugging Java source files. Finally repeated practice can make the learners to understand easily the key concepts of Java language. 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.
