This study examined acculturation stress resulting from socio-demographic characteristics and psychological and social status of married immigrant women residing in the Jeonbuk region. Data were gathered from married immigrant women who were participating in non-profit agencies offering multi-cultural services and those who worked for business offices and stores in the Jeonbuk area. A structured self-administered questionnaire was used. A total of 280 questionnaires were distributed, and 210 were returned. Twenty three questionnaires were excluded from the study because of invalid responses, providing a final data pool of 187 responses. Hierarchical multiple regression analyses revealed that Korean language ability and levels of depression were significantly associated with acculturation stress among married immigrant women. Based on the findings of this study, interventions for reducing acculturation stress among married immigrant women and implications for future studies are discussed.

The development of technology provides and increases security as well as convenience for humans. The development of new technology directly affects the standard of life thanks to smart home automatic control systems. This paper describes a door control, automatic curtain, home security (CCTV, fire, gas, safe, etc.), home control (energy, light, ventilation, etc.) and web-based smart home automatic controller. It also describes the use of ARM (Advanced RISC Machines) for automatic control of home equipment, a Multi-Axes Servo Controller using FPGA (Field Programmable Gate Array) and PLC (programmable logic controller). Additionally, it describes the development of a HTML editor using web auto control software. The tab loading time (7 seconds) is faster when using ARM-based web browser software instead of Chrome and Firefox is used because the browser has a small memory footprint (300M). This system is realized by web auto controller language which controls and uses PLCs that are easier than existing devices. This smart home automatic control technology can control smart home equipment anywhere and anytime and provides a remote interface through mobile equipment.

The existing design materials by document type are restricted in searching and acquiring necessary design information because the materials consist of huge information and various document types. This study suggests a methodology to develop an electronic technical manual that can manage construction design materials by XML-base integrated information system. Electronic technical manual for design materials can provide visualized information through various multimedia tools such as multi-link, virtual reality and animation. Using an integrated electronic manual for construction project can prevent to miss necessary design information. The results of this study includes a data flow diagram to develop an interactive electronic technical manual (IETM) for construction design information. Finally the study suggests some scenarios for practical use and quantitative analysis of application effect analysis by AHP method.

We model a moving object as a sizable physical entity equipped with GPS, wireless communication capability, and a computer such as a PDA and mobile phone. Furthermore, we have observed that a real trajectory of a moving object is the result of interactions among moving objects in the system yielding Multi-points instead of a line segment. In this paper, the new types and operations are integrated seamlessly into the moving object framework to achieve a relatively simple, consistent and powerful overall model and query language for constrained and unconstrained movement.

This paper proposes a design of stepper motor control in microstep driven mode using FPGA (Field Programmable Gate Array) for hardware implementation. The methods to drive stepper motor in microstep excitation mode are to control of the controlling currents in each phase windings of stepper motor with reference signals. These reference signals are used for controlling the current levels, the required variation of current levels with rotor position can be obtained from the ideal linear or sinusoidal approximations to the static torque-displacement ($T-{\theta}$) characteristic curve. In addition, the hardware implementation of stepper motor controller can be designed uses VHDL (Very high speed integrated circuits Hardware Description Language) and synthesis using an Altera FPGA, FLEX10K family, EPF10K20RC240-4 device as target technology and use MAX+PlusII program for overall development. A multi-stack variable-reluctance stepper motor of Sanyo Denki is used in the experiments.

In this paper, we propose an OFDM system with a pre-equalizer which pre-distorting a transmission signal to compensate for the degradation of the system by the intersymbol interference and multi-path fading at the high-speed multimedia communications. We model an OFDM system by using C language, a simulation was performed. As a result, there was a performance of BER is about 7dB at $10^{-3}$, improved to $10^{-4}$ on the MMSE property also $10^{-3}$.

Motor aphasia is an affection frequently caused by insult of the left middle cerebral artery and usually accompanied by a large lesion involving the Broca's area and the adjacent motor and premotor areas. Therefore, a patient with motor aphasia commonly shows articulatory disturbances due to failure of the motor programing of speech sound. Objective assessment and treatment of phonologic programing is one of the important aspects of speech therapy in aphasic patients. We analyzed the speech disorders acompanied with motor aphasia in a 45-year-old man using a computerized sound spectrograph, Visi-$Pitch{\circledR}$, and Multi-Dimensional Voice $Program{\circledR}$. We concluded that a computerized speech analysis system is a useful tool to visualize and quantitatively analyse the severity and progression of dysarthria, and the effect of speech therapy.

To realize GIS on internet two methods are possible. One is using java language and the other is using window API that interface with internet WWW HTTP protocol. GIS program needs to extract, classify, store in various geospatial data. But WWW HTML are statical and Impossible to input multi points and area selectioning. This study applied JAVA in Web GIS so that may handle various geographic data on internet, communicate interactively GUI interface and present, modify and powered with various means of cartographic visualization

Proportional directional control valves (PDCVl adjust the amount of flow as well as flow direction in response to an electrical signal. This valves includes direct operated valves with or without spool position feedback. This paper investigates if it is possible to control pressure of fluids by means of the PDCV. A pressure signal is feed back to the Proportional-Integral (PI) controller, which is based upon a personal computer (PC). The PI control algorithm is implemented in a graphical programming language of LabVIEW. The results of experiments show the PDCV can be used a multi function valve of pressure control as well as direction control.
