For the convenient use of high performance microprocessor in motor control, peripheral devices are needed for converting its control signals to compatible ones for motor drive. Customized devices are not plentiful far these purposes and their functions do not usually satisfied designers specification. The designers used to implement these functions on FPGA or CPLD using hardware description language. Then, in this case unessential programs are needed for control the peripherals. In this paper, a unified device model that links peripheral devices, including especially the pulse width modulation controller and the quadrature encoder interface device, to an interrupt controller is proposed. Advanced functions of peripherals could be achieved by this model and unessential programs can be simplified. Block diagrams and flowcharts are presented to illustrate the advanced functions. This unified device was designed using VHDL. The simulation results were presented to demonstrate the effectiveness of the proposed scheme.

This paper describes the implementation of a 4 channel embedded DVR system. It receives analog video from CCD cameras and converts to 640${\times}$480 CCIR-656 digital video by 30 frames/sec. These digital images are compressed to the wevelet transformed image using hardware codec which is capable of 350:1 real-time compression and decompression. The DVR is working on linux and it implemented on an embedded system which is based on StrongARM processor. For the interface between processor system module and image processing module, GPIO and memory control module are used, device drivers are developed. Linux kernel source is customized. This paper provides techniques of embedded system development and embedded linux porting.

This paper proposes and implements a mobile service and web service integration for utilizing public bicycle sharing system NUBIJA. The NUBIJA system is operated by Changwon City, GyeongNam since 2008 and maintains 247 unattended bicycle sharing terminal on the city. Average users per day of the NUBIJA are more than 8,000 and many users want to get more services from their mobile phones. We implemented realtime mobile bicycle rental and return information service. The informations are acquired from each terminal kiosks and we integrated the information and location based services(LBS) on iOS and Android platform. In this paper, we described an integration services between web and mobile application and shows graphical user interface for highly customized on mobile platforms.

The evolution of telecommunications has raised the profile of many segments of the network that were not previously considered important. Until recently, basic telephony existed with the extension of passive cables without any particular user network interface. In the area of data communications, the introduction of flexible packet switching has allowed the network to evolve in a far more efficient manner. To overcome such separated network problems and business needs of both users and network providers, the integrated narrowband ISDN concept is being developed in most countries for implementation in the public switched telephone network (PSTN). The targets of ISDN, in my opinion, can be explained as follows : To the user, ISDN should provide the services at any time, at any place, through any media. To the business customer using PABX or LAN applications, ISDN should introduce customized services rapidly and also, ISDN should be developed by the modular hardware and software design approach in order for new services to be introduced rapidly and effectively. Software can be also developed by non-expert local staff to cater for adopting new user's service requirements immediately. Finally, ISDN will be able to increase business chances and benefit both users and operating companies.

In this paper, we present a new specific and customized interface tool with parameter identification of Modified Butterworth-Van Dyke models for ladder bulk acoustic wave filters. The aforementioned tool is easy to use and flexible because it allows simulations and reengineering to be conducted in an application. A modular design approach is applied to simplify the extension of the proposed tool for different topologies. The proposed tool was validated using measurements from an aluminum-nitride based ladder BAW filter dedicated to the frequency ranges of the Universal Mobile Telecommunications Service and standards and Wideband Code Division Multiple Access.

웹 2.0의 도래와 더불어 웹 문화의 변화가 급속도로 변하고 있다. 기존의 정보 이용자는 정보 제공자가 제공하는 정보를 단순히 받아보는 수동적인 입장에서, 사용자가 정보를 창출하고 변화를 이끄는 1인 미디어의 시대가 왔다. 이러한 정보의 홍수 시대 속에서 우리가 원하는 정보의 요구량는 하나의 웹 페이지의 정보만으로는 충족될 수 없다. 이에 일률적이고 비슷한 이미지와 정보 배치를 보여주는 웹 페이지들을 좀 더 자신의 개성을 살려 표현하고, 사용자에게 맞춰진 정보들로 구성할 수 있는 맞춤형 개인화 웹 어플리케이션을 제안한다.

본 연구는 야간 라이딩을 위한 패브릭 일렉트로닉스 기반의 안전 보호용 스마트 애슬레져 패션 개발 연구를 목적으로 하며 인간 친화성이 강화된 Fabric LED Display와 Fabric Capacitive touch sensor를 전도성 원사를 개발 및 활용하여 탈·부착 형태로 설계하여 구현하였다. 이러한 모듈의 탈·부착성은 다른 애슬레져 제품과 기능적·심미적인 요소를 교환 및 호환을 할 수 있도록 설계하여 기능뿐만 아니라 디자인의 다양화가 가능한 커스터마이즈 시스템으로 기존 제품들과 차별화된 스마트 애슬레져 패션 제품을 제안하였다는 점에서 연구의 의의가 있다. 후속 연구에서는 Fabric Electronics를 활용하여 착용성과 유연성이 강화된 직물의 물리적 속성에 적합한 직물센서를 개발하고 이를 활용한 커스터마이즈 스마트 패션을 제시할 예정이다.

With the development of medical care in the 21st century and the rapid development of the 4th industry, electronic devices and household goods taking into account the physical and mental aging of the silver generation have been developed, and apps related to health and health are generally developed and operated. The apps currently used by the silver generation are a form that provides information on diseases by focusing on prevention rather than treatment, such as safety management apps for the elderly living alone and methods for preventing diseases. There are not many apps that provide information on foods that have a direct effect and nutrients in that food, and research on apps that can obtain information about individual foods is insufficient. In this paper, we propose an app that analyzes food factors and provides self-medication for health promotion of the silver generation. This app allows the silver generation to conveniently and easily obtain information such as nutrients, calories, and efficacy of food they need. In addition, this app collects/categorizes healthy food information through a textom solution-based crawling agent, and stores highly relevant words in a data resource. In addition, wide deep learning was applied to enable self-medication recommendations for food. When this technique is applied, the most appropriate healthy food is suggested to people with similar eating patterns and tastes in the same age group, and users can receive recommendations on customized healthy foods that they need before eating. This made it possible to obtain convenient healthy food information through a customized interface for the elderly through a smartphone.
