This paper presents new type remote home automation that can control and manage hi-directionally and efficiently home appliances and home security systems in home through Internet. The system is used virtual reality technology to construct very easy user interface and used Internet as network for remote control. Here, the user interface is 3D GUI which gives user feeling to be at his home on web-browser, and also shows him present state of control objects at home. This system has been implemented on the basis of Java and VRML. In this paper we propose the internet-based remote control system, and show usefulness of the suggested system by applying to home automation system.

For many applications particularly in navigation system, a three-dimensional representation improves the usability of information. This paper introduces 3D Graphical User Interface (GUI) of indoor location tracking system, 3D Navigation View. The application provides users a 3D visualization of the indoor environments they are exploring, synchronized with the physical world through spatial information obtained from indoor location tracking system. It adopts widely used Virtual Reality Modeling Language (VRML) to construct, represent, distribute and render 3D world of indoor environments over Internet. Java, an all-purpose programming language is integrated to comprehend spatial information received from indoor location tracking system. Both are connected through an interface called External Authoring Interface (EAI) provided by VRML. Via EAI, Java is given the authority to access and manipulate the 3D objects inside the 3D world that facilitates the indication of user's position and viewpoint in the constructed virtual indoor environments periodically.

The development of distributed databases using a distributed object technology is more popular than ever before because the current computer system environment is adaptable for a use as well as the cost of the integration of legacy systems is cheaper than making a new application. In schools, development of an integrated system consisted of many stand-alone databases give a teacher and an administrator the convenience of managing the database in a school and the ease integration of data in it. Therefore, this research is to design and implement the 3-tier distributed database using CORBA, Java and JDBC.

CpG is the pair of nucleotides C and G, appearing successively, in this order, along one DNA strand. It is known that due to biochemical considerations CpG is relatively rare in most DNA sequences. However, in particular subsequences, which are a few hundred to a few thousand nucleotides long, the couple CpG is more frequent. These subsequences, called CpG islands, are known to appear in biologically more significant parts of the genome. The ability to identify CpG islands along a chromosome will therefore help us spot its more significant regions of interest, such as the promoters or 'start' regions of many genes. In this respect, I developed the CpG islands search tool, CpG Islands Detector, which was implemented in JAVA to be run on any platform. The window-based graphical user interface of CpG Islands Detector may facilitate the end user to employ this tool to pinpoint CpG islands in a genomic DNA sequence. In addition, this tool can be used to highlight potential genes in genomic sequences since CpG islands are very often found in the 5' regions of vertebrate genes.

The proposed courseware using Java applets and VRML provides the improved learning methods which can enhance the interests of students. To cope with difficulties of science education presents 3 dimensional anmation function using VRML. The courseware helps students to improve understanding of machine easily seen in our life and interest of science education. It can be widely used to improve the efficiency of science education.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

Because of the change of computing environment, an agent technology is spotlighted recently. By deploying agent distributedly in network and offering the necessary service quickly in place easing realization of service, the enlargement of the effectiveness of network is necessary more and more. In this paper, agents programmed in java are distributed in place easing realization of service in network. And a manager connects to agents and informs URL of service code of the agent. This paper implements distributed computing environment in which agent downloads service code from URL of service code, executes the code, and returns the result of execution to manager.

In the knowledge based society, the development of creative human resources is one of the core factors for securing a national competition power. Especially in the software industries, the development of human resources who can solve a problem creatively by applying object oriented programming technique which is a update Programming technology is required. In this paper, we designed a lecture plan and produced it into a course contents which could be run on a online learning system. The teaching focuses of the developed course are the development of problem solving ability and object oriented design and programming ability through Java.

There are a lot of shopping malls in Internet and most of consumers want to buy good goods in cheap price through the shopping malls. To support them, many sites for price comparison are constructed. But man or woman search many shopping malls and insert their price informations into database that the price comparison sites own. To overcome this disadvantage, virtual shopping malls are builded. These virtual shopping malls are connected and cooperated a lot of affiliated existing shopping malls for the cheapest price information. But, these virtual shopping mall are connected to those existing shopping malls in synchronous. So If they are connected to many existing shopping malls, we have to wait long time because of searching for many existing shopping malls. In this paper, we designed and implemented a virtual shopping mall that connect to many existing shopping malls in asynchronous. For a asynchronous communication between this virtual shopping mall and many existing shopping malls, we used JMS (Java Message Service) that is a standard Java API for MOM (Message-Oriented Middleware).

Recently, a great many people are concerned about promoting their health because medical science and scientific technology has become much larger and more develop. Thus, the person who interested in health wants to confirm his condition whatever he may take a meal or exercise. But it is disappointed of our expectation. By reason that many people doesn't know what changes will occur in their body. In this paper, we are going to introduce our Health Care Managing System which could display a physical variation, in addition, we will also propose how to control serial data from wireless sensors. We implemented this system using ZigbeX and Java application.
