To keep the online medical records available to anyone without constraint of time and space, introducing EMR (Electronic medical record), which is a clinical support management system. The purpose of this study is to develop interface standard of clinical test device. Integration and sharing of medical information is faced with enormous obstacles because medical organizations and associated companies are separately developing the interface. I hope that multi-function management system with workstation concept is operated to efficiently transmit clinical device result data based on this study. Transfer of precise medical result data available for decision making will improve quality of health care service.

A new low-voltage CMOS interface circuit with digital output for piezo-resistive transducer is proposed. An input current sensing configuration is used to detect change in piezo-resistance due to applied pressure and to allow low-voltage circuit operation. A simple 1-bit first-order delta-sigma modulator is used to produce an output digital bitstream. The proposed interface circuit is realized in a 0.35 ${\mu}m$ CMOS technology and draws less than 200 ${\mu}A$ from a single 1.5 V power supply voltage. Simulation results show that the circuit can achieve an equivalent output resolution of 9.67 bits with less than 0.23% non-linearity error.

This paper presents a study on the introduction of User Model-Based Dialogue System. Also we present a plan-based Korean dialogue system as a natural language database user interface for product search. The system can be characterized by its support for mixed initiative to give user more control over dialogue, employment of user model to reflect user's preferences, alternative solution suggestion if there is no product matched exactly to user's requirements, handling circumlocution which frequently occurs in dialogues. The user modeling shell system BGP-MS is adapted for the system. The system provides for a user-friendly database user interface by managing dialogue intelligently. By its implementation and test, it has been shown that the user model-based dialogue system can be utilized effectively for product search.

SENT (single edge nibble transmission) is a serial communication protocol between automotive sensors and ECU (electronic control unit). SENT exploits digital waveform, so it has a simple and cheap architecture without transceiver circuits. Usually it is exploited as an embedded communication interface in the sensors. In this paper, a SENT interface was designed in Verilog HDL, fully complying with SAE J2716. It was implemented in FPGA, and verified on a test board. When it was synthesized, the gate count is about 2,500 gates in 0.18um technology.

In this paper, a miniaturized sensor interface circuit for the respiration detection system is proposed. Respiratory diagnosis is one of the main ways to predict various diseases. The proposed system consists of respiration detection sensor, temperature sensor, and interface circuits. Electrochemical type gas sensor using solid electrolytes is adopted for respiration detection. Proposed system performs sensing, amplification, analog-to-digital conversion, digital signal processing, and i2c communication. And also proposed system has a small form factor and low-cost characteristics through optimization and miniaturization of the circuit structure. Moreover, technique for sensor degradation compensation is introduced to obtain high accuracy. The size of proposed system is about 1.36 cm².

The purpose of this study is to explore physical factor of digital text structure for designing e-Book interface and to develop prototype of e-Book interface by applied these factors. To address this goal, explore factor analysis and confirmatory factor analysis were employed, 237 university students were the participated in this study. According to a result, 29 items for physical feature of digital text structure were developed, 9 factors of digital text structure were also extracted; volume, depth, density, space, layout, format, signal, size, and length. Besides, to identify structure of pre-defined 9 factors, confirmatory factor analysis was conducted. As a result of CFA, the factor structure was supported by all of model fit indices.

This paper aimed to identify the relationship between satisfaction and continuous usage intention of AT(Accounting Technician) certification program using WBI(Web-Based Instruction) in the digital convergence environment. We extend satisfaction and continuous usage intention, technology acceptance model theory by adding usefulness expectation, program interface, expectation confirmation. This study was examined by using the SPSS 21.0 and AMOS 21.0. The results by analysis are as follows. First, usefulness expectation and program interface showed positive effect on the expectation confirmation, usefulness expectation had more significantly effect than the program interface. Second, expectation confirmation had significantly positive effect satisfaction, continuous usage intention. Also expectation confirmation was influenced by continuous usage intention rather than satisfaction. Third, satisfaction had positive sign on the continuous usage intention.

Since the advent of digital games, game of the core platform has been changed from the arcade to the mobile device. I consider that I try to seek the direction of the use of game which works for PC and mobile in comparison to analyze the changes in the game graphics. Effects of three types of game platforms on the game graphics, change depends on the game of the genre and game graphics. By reduction of the screen size, a new interface was appeared. However, as directly applying the PC version of the interface, it has brought about a user's inconvenience. I have found that mobile hardware development have not been affecting the game graphics. The common point of PC and mobile, they both have the limit of the platform which they own. There is a need to take into account the differences of graphically elements to use the player language interface.

With the start of digital broadcasting, TV screen, there is provided a new broadcast service is called EPG (Electronic Program Guide) that can be retrieved directly to a channel or program. However, a study considering the EPG of the user interface on the viewer position is so far insufficient. TV is because everyone watching the media, rather than a specific layer is necessary in order to find easy, intuitive user interface for the program to the viewer. That is, it is possible to quickly find the program to select the attributes that the TV viewer can be easily understood by using the EPG. To this end, this paper first genres which are representative of the properties that distinguish a TV program, time, rating, etc. were systematically classified. So viewers the values of the properties but to specify organized by the EPG, the order of attributes that specify the value we design a user interface that can be selected as having easy. And compare the superiority of the function evaluation of the two through the EPG in the EPG Usability Test proposed by the EPG with the existing commercial paper.
