The purpose of this study is to develop the optimal system(AAC device), which helps a person with a profound communication disorder to communicate with other people. Therefore, this system includes the user interface enhancement that is the user adaptation mode algorithm. The symbol is made with a text and an icon which is converted into Korean. The message contiol operates scanning and adjusts rate control of row-column scanning and linear scanning. This embedded system includes voice input/output and voice recording as well suggested method that could apply optimal device access algorithm from clinical environment. Therefore, we are experting that even the current system itself will be able to improve the life quality of people who need to communicate with the help of devices.

Electric shock due to the increased use of power, equipment accidents, electrical accidents, such as electric fire and also continues to grow. To prevent electric shock accidents, an experience education is more effective than indoctrination education. But an electric shock experience education system required a proper physical stimulation on human body to experience electric shock. In this study, we conducted a study to take advantage of the realistic haptic interface using a low-frequency type experiential learning and prevention education. Results of this study could be applied to an electric shock experience education system.

이 논문은 인터넷이나 정보통신망을 이용하여 멀리 떨어져 잇는 기기를 제어하거나 감시하는 원격 제어 시스템을 개발하는 것을 목표로 하고 있다. 이 때 원격 제어용 프로토콜로는 SNMP(Simple Network Manatement Protocol)를 사용하였고, 지역적으로 멀리 떨어져 있는 기기에 대한 실시간 제어 및 감시를 위하여 자바(Java) 환경의 소프트웨어를 구축하였다. 도한 이 논문에서는 네트워크 기기와 응용 기기 사이의 인터페이스 컨트롤러를 제안하여 대부분의 기기에서도 이 원격 제어 시스템을 사용할 수 있다는 가능성을 보였다.

In this paper, we proposed the multiple access control of RS232C Serial Communications protocol using collision sense method. The communications wires of data transmission and reception are tied together through the buffer each to connect to the multiple communication channels. The hardware interface and control program are designed to build the prototype system and the experimental multiple access communications network is built by multiple PC systems and the transfer completion rate results are shown.

In an intelligent man-machine interface, it is very effective to support human thinking and to be in communication in some intuitive fashion. For this, sharing experience between the party concerned, human operators(s) and the interface is essential. It is also necessary to keep mutual understanding in some conceptual levels. Here in the present paper, figures which are an aspect of concepts and form a basis of mental image are discussed.

Brain Computer Interface (BCI) is a communication pathway between devices (computers) and human brain. It treats brain signals in real-time basis and discriminates some information of what human brain is doing. In this work, we develop a EEG BCI system using a feature extraction such as common spatial pattern (CSP) and a classifier using Fisher linear discriminant analysis (FLDA). Two-class EEG motor imagery movement datasets with both cued and uncued are tested to verify its feasibility.

Layered structure of the Korean terrestrial Digital Multimedia Broadcasting (TDMB) transmission system for multimedia broadcasting service is presented in this paper. We made a switching module which is called the Ensemble Remultiplexer. It is designed to remultiplex the Ensemble Transport Interface (ETI) for T-DMB service. This paper describes the remultiplexing process of the Ensemble Remultiplexer.

With the role of cell phones in today's society as a digital personal assistant as well as the primary tool for personal communication, it is possible to imagine the involvement of cell phones in almost any type of crime. The progression of a criminal investigation can hinge on vital clues obtained from a cell phone. This paper will be concentrated on CDMA system phones and focus on the data extraction for cell phone forensics. Especially, the data acquisition method of JTAG interface access to memory chip will be covered.
