We describe a research about remote control of mobile robot based on voice command in this paper. Through real-time remote control and wireless network capabilities of an unmanned remote-control experiments and Home Security / exercise with an unmanned robot, remote control and voice recognition and voice transmission are possible to transmit on a PC using a microphone to control a robot to pinpoint of the source. Speech recognition can be controlled robot by using a remote control. In this research, speech recognition speed and direction of self-driving robot were controlled by a wireless remote control in order to verify the performance of mobile robot with two drives.

Nowadays, HD(High Definition) broadcasting is popular all over the world. Many people want to record the HD level contents. BD(Blu-ray Disc) is developed to satisfy the needs. BD player for home movie system was manufactured already. ODD maker will produce BD Drive for PC(Personal Computer) within few months. Backward Compatibility is very important point in BD Drive. Until now, two OL(Object Lens), two optical pickup and two deck system are proposed. We suggest Single OL system in this paper. Single OL is composed of two optical parts and it's weight is heavy. We introduce the magnetic circuit composed of two 3-Pole magnets. In Spite of heavy OL, We achieve the New Actuator which has high performance.

Adapting content services to the needs of the users requires content adaptation for context and sensibility. Adapting to context may necessitate distinguishing between video delivery to a PC versus a smart phone, while adapting to sensibility may necessitate between video delivery outside, in a quiet environment, or at home, or offering different movie choices on a sunny summer day, a cold winter day or a holiday season. One key area to address in providing adaptive content services is the design of the delivery system architecture of the adaptive content server. This paper describes several alternatives for this architecture, and outlines some additional concerns that must be considered when the chosen architecture is implemented.

본 논문은 입/출력 관계가 불명확한 가전제품 제어에 인공신경회로망을 응용하여 지능형 제어기를 구현하는 방법에 관한 것이다. 다층신경회로망을 사용하고 Error Back Propagation 학습방법에 의하여 학습되도록 한다. 제어대상물에서 알 수 있는 정보는 입력값과 이에 대응하는 출력값 뿐이며 입력과 출력에 대한 관계를 수학적으로 모델링하기 어려운 경우이다. 인공신경회로망을 이용한 제어를 위하여 Neural Network Emulator(NNE)와 Neural Network Controller(NNC)가 개발되며 각 신경회로망의 초기하중백터는 제어대상에 오프라인 학습으로 결정하고, 자동조절과정에서 온라인 학습하여 새로운 대상제품 상황에 적응하도록 설계되었다. 제안된 지능형 제어시스템은 PC를 이용하여 실시스템에 적용하여 검토되었다.

With the rotational speed of the hard disk drive (HDD) increased, the low frequency structural vibration induced by the unbalance force gives rise to the structure home noise of the personal computer, and finally degrades the noise quality. As the unbalance of the hard disk drive is decided by the mechanical assembly allowance between clamping and platter disk, there is limit to control this unbalance by the improved assembly method. To improve the noise and vibration performance of PC, basically the unbalance of HDD needs to be measured absolutely and reduced during the stage of the disk assembly. This study introduces the HDD unbalance measurement methods of the absolute magnitude based on the mobility concept, and the unbalance location information with the acceleration orbit.

The branch of the laser imaging has implemented 3D graphics, color graphics and video images after it drew a simple image by development the salvo's X-Y scanner in 1960 year. Now it is used as the multimedia show of an event and an advertisement. The latest issue of laserist is the ability to generate laser images with the same ease and speed associated with traditional computer graphics. All laser projector used in the interior of a countris was imported from other country. The most important component of the laser projector is the speed and the accuracy of a actuator and the software which actuates the controller on computer. In this paper we developed the controller with a universal joint and the PC based user interface software in order to implement the laser image of two dimension, and will prepare the base of beginning the home laser projector

This study includes noise automatic inspection system for washing machine auto-transmission one of modern home necessary. We effort to find and certificate sound noise source by sound power and sound intensity, and apply to frequency analysis in vibration related sound noise. still more we have been studying to data acquisition and programming for MS VisualBasic version 5.0. System component is below. 1) Pentium PC or data acquisition. 2) DSO for noise acquisition. 3)S/W for comparison and decision. 4) I/F Board for data communication. Wave form data through the DSO are converting to ASCII code data. The ASCII code through binary converting S/W. Finally we will making noise monitoring system and automatic inspection system.

The purpose of this study is to examine the realities of knowledge and attitude about smoking among high school students, to analyze the relation among knowledge of smoking attitude about smoking, and smoking behavior. For the data, 1,522 boys' high school students living in Pusan were selected. The data were analyzed with the SPSS PC+ statistical package using t-test, multiple regression and path analysis. The main results are as follows; First, smoking group has lower knowledge of smoking than non-smoking group. Second, smoking group has more positive attitude about smoking than non-smoking group. Third among the demographic variables pecket money, scholastic attainments, grade, SES, and religion influence on smoking behavior directly and indirectly. Fourth, among the smoking environmental variables parents' smoking, sibling's smoking. the number of smoking family. close friends' smoking, the number of smoking friends, family's thought about smoking, knowledge of smoking attitude about smoking influence on smoking behavior directly and indirectly.

The Purpose of this study is to investigate the marital conflict degree, and find out how demographic variables have and effect on marital conflict. For the data , 521 Married woman living in pusan were selected. The data were analyzed with the SPSS PC+ statistical package using M.SD. Factor analysis. Pearson's correlation, one-way ANOVA, scheffe-test, multiple regression. The main results are as follows: First, items were loaded eight resource categories such as character, sexual, children, communication, husband' family, spousal digression, economic difficulties and financial affairs problem. Second, the degree of marital conflict is relatively middle. Taking a look at each conflict factor, conflict of character problem is the highest, the next is communication problem and the third is children problem. Third, among family environmental variables level of education, income, job of husband and husband's dissatisfaction with job hove influence on the marital conflict.
