Because of an rapid increase of using a wireless Internet, the originally used communication of 2.4 GHz band was saturated and crossed and there were some problems. According to this, the development of a wireless Internet technology of 5 GHz Band proceeded. In the thesis we researched a Square Slot Microstrip Patch Antenna available in 5 GHz band of wireless communication. The research designed and analyzed the Antenna through HFSS. Ultimately, we compared and analyzed made Antenna through a Network Analyzer.

The information technology such as personal computers and the internet has become a critical factor in forming a common and popular culture over the last few decades. Those technical inventions have transformed the educational environment. In the past, the only way to get an education was for students to attend schools or private institutions by themselves. In contrast, the internet enables people to learn from a distance by using cyber-education courses and many e-learning contents are provided. Based on those infrastructures, students can be educated in a convenient and flexible way without totally depending on attending school. The purpose of this paper is to examine what the effect of cyber-learning at home is, and to analyse what the problem is? Lastly, this paper also suggests measures to alleviate the adverse effects of it.

This study is the design and implementation of digital textbooks for elementary school computer education based on smart phone. It suggests how to cultivate self-directed learning ability depending on the level and selection of individuals by maximizing on interaction as advantage of digital textbooks. As the content of the digital textbooks, this study used Excel's charting capabilities. As a result of the evaluation of elementary learners having a implemented digital textbook, execution time of creating a chart is reduced in comparison with paper-based textbook user group.

Since 2001, we have taught computer in elementary school to become the advanced country of IT in the 21C. However, people criticized that ICT education which is consisted mainly of the computer skills is not appropriate for information literacy education. In 2005, "ICT Education Guide Rev." is published. Thereafter, information literacy education has systematic frame. The experts emphasize the importance of performance assessment. Computer education can become the problem solving education if the performance assessment carried out. However, it is not successful without the good rubrics for performance assessment In this paper, we developed the rubrics for performance assessment for "presentation document writing".

Due to the rapid development of smart phones, smart phone users grew, expanding communication between the service users has been enabled by the application's service. Difficult to find a service that allows you to know the quality of school meals and the expectations of these applications. In addition, the existing application works only with a particular device, it is difficult to compatible devices. Thus, based on the HTML5 hybrid application were developed and this feed can be monitored by the students of the school, the communication can be formed.

Essay education has been multifariously accomplished through school curriculums, private institutions and online education systems. However we can easily find misspellings from students' writing, and them still not being able to describe their own experiences logically and skillfully in schools. In this paper, we propose the web-based essay correction system using mash-up service, ECSUM, implemented for improvement of a students' logical writing ability applying a logical writing correction module with six steps. Using the proposed system, students can obtain logical writing skills using a mash-up service and teachers can help their students to improve their logical ability of self-expression.

This study is intended to analyze unscientific concepts shared by high school students regarding planet movement; produce a learning program to address these concepts; and investigate what impact the application of the program to planet observation and classroom lessons may have on their grasp of planet movement and their attitudes toward science at large. Application of the learning program developed in this study to teaching and learning courses led to the discovery that the program is a useful tool to enhance students' understanding of planet movement. These results suggest that a variety of programs including planet movement activities that may keep students interested in science should be continued. The above study results may be utilized in geoscience teaching and learning. It is deemed necessary to develop better learning programs and study teaching and learning methods regarding not only planet movement but also other spheres.
