For the active communication between school and the parents, this paper proposes the educational information delivery system running on the wireless internet using a cellular phone as well as on the existing wired internet using a PC. First, we have performed the survey on what kind of educational information the parents of the students want. The participated parents are 135 parents of the students in elementary, middle, high, and vocational high schools in Seoul. According to the result of this survey and the analysis on the operational mobile and educational sites, the educational information for parents, and the user interface of a cellular phone for the convenient access of mobile information are designed. Also, this mobile educational information system uses SMS for the parents to access the educational information easily.

This study was about design and development of the Mobile Learning Evaluation Announced Systems, which could operate the e-learning and send the result of that to the parents. From this, teachers and parent can communicate with each other dynamically. Especially, this system does not simply present results of student' learning but provide the extra learning which can make up for student' wrong questions in the base of the evaluation standard. this paper suggests this total learning solution so that parents can perceive the state of their children's learning under the mobile learning environment.

Recently, universities have difficulties in operating the normal curriculum because fresher's basic academic ability is declined. It causes campus misfits so managing students is also not an easy matter. The education system that focuses only on college entrance exams is one of the reasons why this phenomenon occurred. Activity with self-directed Learning Community to know learning level themselves and execute systematic studying habit is essential for improving this problem. This activity can help students understanding and having interest in class and be motivated to study. But it had burdened tutors with submitting activity report in written form. In this paper, we suggest the Mobile Based Activity Report Submission System which can be the solution of the problem that the Self-directed Learning Community System has. This system reduces the emotional burden to write the reports and manages them efficiently.

Many learning methods are recently being proposed for web-based remote education and a method commonly applied to web-based learning is learning through questions. In the existing methods, the difficulty of questions is chosen by learners in accordance with their level or questions are selected dynamically. As these methods are simply based on difference among questions presented, however, it is hardly possible for learners to study according to their abilities. To solve the problem, we adjusted the difficulty of questions presented based on information on individuals' weak points for different types of questions. Under the system individuals can learn by applying information on their abilities with regard to the type and difficulty of questions repeatedly, so the system can provide more effective distance learning. To overcome space restrictions in learning, also, we design and implement a mobile study system on the top of PDA platforms.

Recently, retrieval of various video data has become an important issue as more and more multimedia content services are being provided. To effectively deal with video data, a semantic-based retrieval scheme that allows for processing diverse user queries and saving them on the database is required. In this regard, this paper proposes a semantic-based video retrieval system that allows the user to search diverse meanings of video data for electrical safetyrelated educational purposes by means of automatic annotation processing. If the user inputs a keyword to search video data for electrical safety-related educational purposes, the mobile agent of the proposed system extracts the features of the video data that are afterwards learned in a continuous manner, and detailed information on electrical safety education is saved on the database. The proposed system is designed to enhance video data retrieval efficiency for electrical safety-related educational purposes.

The robot has a smart function with the development of mobile devices and provides safety and convenience to our lives. In this paper, we study multiple robotcar system based on mobile that can be controlled by remote control. Robotcar with arduino can be controlled from server, but it also designed to be controlled by mobile devices as controller's necessary. Besides, it have feature that many robotcars can be controlled at the same time by using several mobile devices which select each robotcar.

Current computer education is moving its focus from using oriented education to improving students' creativity and problem solving ability by computer science education. Robot programming education is becoming a major research issue of computer education in the context of creativity education. One of the mainstream ideas of prior research about robot programming is the effect of robot programming. Another is curriculum development of robot programming. But, the focus of current research is moving toward teaching methods of robot programming. The theme of this research is to use examples in robot programming. Example programs are considered the most useful type of material both by the students and the teachers. Example programs play a important role in learning to program. They work as templates, guidelines, and hints for learners when developing their own programs. In this study, I developed a example-based robot programming support system. Due to the trends of smart learning, I developed this system as a mobile web application.

Effective information delivery between school and parents is very important in preschool and the lower classes of elementary school. It is because by the fact that the traditional method of information delivery relies on kids to deliver school information but they are not sufficiently matured enough to deliver information correctly. In this point of view, this paper proposes a new information delivery method combining internet homepage and mobile message services and develops a information delivery system to support that method. Proposed method and developed system are able to correctly deliver information within the desired time and they do not increase the burden of communication costs and teacher's works.

Recently, there has been much research to develope and apply RFID technology, which has a kcy role in the upcoming ubiquitous society, in many fields such as physical distribution, traffic control, medical service, and so on. However, there has been little research on a ubiquitous education or learning including 'u-Campuses' and 'u-Libraries'. Based on the characteristics of RFlD, this paper proposes a system for English learning required in globalization age. RFID tags and sensors utilize wireless communications to track the location and status information of the user to deliver English situated learning services. The current RFID-based system should use quite a different rniddleware, compared with a general-purpose middleware on server or desktop. The RFID system is used on a mobile PDA and consists of essential APIs such as reader and tag control, queue, and filter management.

As the educational media tends to be more digitalized and individualized, the learning paradigm is dramatically changing into e-learning. Existing on-line courseware gives a learner more chances to learn when they are home with their own PCs. However, it is of little use when they are away from their digital media. Also, it is very labor-intensive to convert the original off-line contents to on-line contents. This paper proposes education mobile contents(EMC) that can supply the learners with dynamic interactions using various multimedia information by recognizing real images of off-line contents using mobile devices. Content-based image retrieval based on object shapes is used to recognize the real image, and shapes are represented by differential chain code with estimated new starting points to obtain rotation-invariant representation, which is fitted to computational resources of mobile devices with low resolution camera. Moreover we use a dynamic time warping method to recognize the object shape, which compensates scale variations of an object. The EMC can provide learners with quick and accurate on-line contents on off-line ones using mobile devices without limitations of space.
