Our study illustrates how the use of web materials written with Mathview affects vocational high school students' learning in terms of formative evaluation. Our first attempt to develop high school math with Mathview has been guided according to current math texts due to highly structured format of math contents and low learning competencies of vocational high school students. The 6 female students who participated for about 12 hours in this study revealed their responses through interview data. descriptive surveys and field notes. Contrary to the original expectation. the results of data analysis showed that the students seem to prefer using conventional learning methods even though they were motivated by powerful graphical display of Mathview and algebraic manipulation capability. The overall responses of those.

Students, who are studying the field of accounting, have to learn and practice statistics in order to analyze the current social status and to predict the Suture trend. however, students have a strong tendency to avoid the statistics lessons, which are dealing with complicated numbers, mathematics, various equations, and so on. This paper aims to construct a stimulating environment for learning statistics and develop an actual lesson on the Internet, Which students can study by practicing directly. The lesson is fully interactive and visualized by using multimedia technologies. The effectiveness of the experiment is measured by survey questions to the students who used the lesson.

In this paper, we introduce a new programming learning system for young students. The programming learning system consists of a LED display kit and a web-based flowchart system. The LED display kit acts as an output device by way of displaying lights while following a set of instructions given through a flowchart programming. In the flowchart system, the students use symbolic variables for the calculation and can get various displays or animations after creating a flowchart by drag-and-drop. Then we describe the survey results of various programming classes using our system between fall 2005 and spring 2009. The programming teaching was conducted with diverse groups such as elementary school students, gifted students, college students, and teachers etc. The responses from our in class surveys were generally positive.

Today, the typical web hacking attacks are cross-site scripting(XSS) attacks, injection vulnerabilities, malicious file execution and insecure direct object reference included. Web hacking security systems, access control solutions, access only to the web service and flow inside but do not control the packet. So you have been illegally modified to pass the packet even if the packet is considered as a unnormal packet. The defense system is to fail to appropriate controls. Therefore, in order to ensure a successful web services diagnostic system development is necessary. Web application diagnostic system is real and urgent need and alternative. The diagnostic system development process mu st be carried out step of established diagnostic systems, diagnostic scoping web system vulnerabilities, web application, analysis, security vulnerability assessment and selecting items. And diagnostic system as required by the web system environment using tools, programming languages, interfaces, parameters must be set.

This paper examines users' emotion from both 2D and 3D web interfaces and finds their differences. First, 77 words representing users' emotion were collected from the previous research papers. Second, a web survey system was developed using these collected words and prepared 3 web interface prototypes to collect users' emotions from different types of web interfaces. Finally, a web survey was conducted and its results were analyzed. The result of the survey showed that there were emotional words that were commonly experienced from either 2D or 3D web interfaces. However, it also showed that there were emotional differences between 2D and 3D web interface; 3D web interfaces provide users with specific emotional experiences because of their own characteristics - depth and dynamic movement. It is believed that the words collected from the survey could be the criteria to evaluate the quality of the 3D web interfaces and encourage the research on users' emotion from 3D interfaces.

The school library provides a mobile web service that allows access to the library catalog system, and provides services that reflect the needs of search and consider the characteristics of mobile devices. Therefore, this study conducted a literature review, an analysis of the current status of school library mobile web services, and a survey of the mobile service user experience of students and teachers to find the contents and service plans for school library mobile app services that meet the school library mobile needs. Based on the survey, the contents and design plan of the school library DLS mobile service was prepared. First, the steps were reduced from step 4 to step 3. In the first step, solution of screen clipping errors in registering as a member and various login platforms for accessibility are needed. In the second step, integrated search and detailed search, provision of materials for use and reading education, post-booking activities, guides and announcements on the use of the affiliated school library, inter-loan, and e-books are provided as main menu. In the third step, it was proposed to provide related functions such as reservations as well as the display of the detailed screen of the search results of the collection. This study can be used not only to develop dedicated mobile app services, but also to change current web-based mobile services.

In this Paper. we describe a home health care service using electronic health questionnaires and routine checkup of vital signs Including ECG (Electrocardiography) , blood pressure. and SpO$_2$ (Oxygen Saturation) . This system is for patients at home with chronic diseases, discharged Patients, or any normal people for the Prevention of disease The service requires a home health care terminal and a PC with Interned connection installed at Patient home. The distance health care management center is equipped with a vital-sign and questionnaire interpreter as well as database, Web, and notification servers with UMS (Unified Messaging System). Participating Physician can access the servers at the center using a Web browser running on a PC available to them at any time. These components are linked together through various kinds of data and voice communication channels including PSTN (Public Switched Telephone Network) . CATV(Community Antenna TV) . Interned. and mobile communication network. Following the Physician's direction given to a Patient. he or she uses the home health care terminal to collect vital signs and fill out the questionnaire. When the terminal automatically transmits these data to the management center. the data interpreter and servers at the center process the information fo1lowing the Protocol implemented on the system. Physicians can retrieve and review data corresponding to their Patients and send back their diagnostic reports to the center. UMS at the center delivers the physician 's recommendation to the corresponding patient through the notification server. Patients can also reprieve and review their own records as well as diagnostic reports from physicians. The system Provides a new way of collecting diagnostic information and delivering doctor's recommendation to patients at home for their health management. Future works are needed in the development of new technology for measurements and interpretations of various vital signs .
