This paper proposes an adaptive equalizer with the digitally controlled active variable capacitor. An equalizing amplifier consists of a main amplifier and a source degeneration RC filter which is implemented using the digitally controlled active variable capacitor for area efficiency and linear loss compensation. The active capacitor changes its capacitance by the amplifier gain control, which is based on miller effect. In the simulated results, the proposed equalizer compensates the high frequency loss and extends the data eye width from 0.31 UI to 0.64 UI.

Embodid Community web application program preservation, damage control and resuability uses EJB component that is high breakup object system than existent model 1 web program. Web programs that is in existing hard to exist on course which UI logic is same with business logic and do maintenance and resuability. But, improved resuability of business separating business logic and UI logic by different machine embodying program to use component. Minimizes Teuranjeksyeon and Paeilobeo and embodied in stabler program than existing by using EJB component.

In this paper, we implement the multimedia remote control system by using existing internet service or wired online. We also provide user-friendly convenient environment with developed application program named EzPlay and PC-EPG. The multimedia remote control system consists of integrated wireless transceiver of PC and TV connected USB type and the users can easily use lots of contents because EzPlay program provides appropriate UI mode on the PC and TV screen. The unposed system can operate real-time playing, reserved video receding and data storing function using internet mesh based on signal detecting control theory. The PC-EPG system is implemented by server/client web program and the client program based on visual C++/MFC processes data storing in client computer through TCP/IP. It also provides intelligent function that constructs database according to user's preference.

This paper, discusses about the implementation of the remote control LED Lights in elevator facility Since 1990, the elevator dissemination has greatly increasing. Currently in the elevator most of people they can use smart devices anytime or anywhere to view and retrieve the information by using internet. Therefore, in this paper, efficient management of power LED and LED remote control LED lighting fluid, in order to control features and smart devices can be applied to Web services platform and OS-specific proposals. Additionally based on the configured UI technology and programs offered by the present, and the LED lights are offered through the simulation to efficiently manage technology to demonstrate the usefulness.

A model for the economic design of an pn control charts with an assignale cause is presented and the loss-cost function for control schemes using these charts is derived. By minimizing this function with respect to the three control variables, namely, the sample size, the sampling interval and acceptance number, the economically optimal control plan can be optained. The article shows what influence increasing or decreasing condition, according to changeability of the size of these factors, of expected cost can have on the economy when an attribute control chart is used.

Purpose This study was designed co determine the possibility of HLA typing in the objeccification of constitution. Methods We selected 100 patients who showed Taeyang characteristics, and divided them into Soum-inclined group and Soyang-inclined group. HLA-A, B, DRBI typing was perfomed by ARMS-PCR and PCR-SSOP method. Results Taeyang characteristic group as a whole showed significant difference in A1, A11, B37, B70/71, DRBI*15,DRB1*14 alleles in comparison with normal control group. Soum-inclined group showed significant difference in All, B70/71, Soyang-inclined group in DRBl*15, hard drinker group in DRBl*15, DRBl*13, drink-rejecting group in All, B37, DRBl*7, DRB1*14 in comparison with normal control group. Conclusion : There were significant relations between constitutional information and HLA types.

Considering the singularity of robot, singularity avoidance control of robot is very important. Because it is very difficult structurally to exclude the wrist singularity. Then new control policy is needed to overcome wrist singularity. In this paper, the singularity states of robot wrist was analyzed and control algorithms for 3 and 4 axes robot wrist were proposed. Application results of the proposed control algorithms to the path including singularity showed us their usefulness and validity.

As intelligence of robot is developed, consumer of robot changes by ordinary people. Intelligent service robot is produced to a target of ordinary people. It is risen that need the most service robot business. Among the control mobile robot because using network by real time. Do to appear on mobile phone LCD screen being transmitted image from device that acquire transmit of mobile phone user interface development and real time mobile robot in this study. Use the BREW that is Qualcomm's Mobile platform for mobile phone user interface development. Mobile phone JPEG compression function chooses excellent camera phone and display transmit image which send connection setting screen and mobile robot on LCD screen by real time. At the same time, materialize to make screen that can process button input that can control transfer of robot. Also, Relay Server used to help processing of protocol to control direction of mobile robot.

Objective: This study focuses on the effects of pre-cues informing the location of upcoming visual stimulus on finger movement response in the context of control-on-display interfaces. Background: Previous research on pre-cues focus on attention allocation and motion studies were limited to indirect control conditions. The design of this study aimed to collect data on the exact landing point for finger-tap responses to a given visual stimulus. Method: Controlled visual stimuli and tasks were presented on a UI evaluation system built using mobile web standards; response accuracy and response time were measured and collected as appropriate. Among the 16 recruited participants, 11 completed the experiment. Results: Providing pre-cue on the location of stimulus affected response time and response accuracy. The response bias, which is a distance from the center of stimulus to the finger-tap location, was larger when the pre-cue was given during a one-handed operation. Conclusion: Given a pre-cue, response time decreases, but with accuracy penalized. Application: In designing touch-screen UI's - more strictly, visual components also acting as controllers - designers would do well to balance human perceptual and cognitive characteristics strategically.
