The trend is going to obtain the accurate and fast information to the development of information technology and electronic technology as an important part of corporate management. Press equipment to produce products that target is small and medium businesses. Became so economical real-time production information system(R-PIS) model has been implemented. R-PIS configure the embedded hardware and PC application software. This system is easy maintenance and upgrade that general-purpose PC and a modular hardware devices. Consists of modules such as wireless communication, LCD, Key-pad, memory control, and sensor signal. R-PIS is efficient materials and product management to maximize the productivity of the enterprise.

In this study, which is the basis for industrial presses to target small and medium enterprises with production information system is designed. Production information in real time on-site digitizing and transmitting data to a standard PC is to base operations. Personnel management, safety management, production management is to increase the efficiency. Therefore, at low cost is to encourage computerization within the company. These embedded systems and wireless communication module has a database management program installed in order to raise productivity and competitiveness will improve.

The purposes of this research are presenting a new business model by introducing USN/ZigBee and measuring productivity using BSC(Balanced scorecard), and becoming a cornerstone by presenting a prototype of ServiceScience which is getting more attention from Industrial Engineering and Management. The new business model consists of development of leak current monitoring sensor using USN/ZigBee and the adoption of RCM(Reliability-Centered Maintenance) using knowledge-based system at current distribution. Additionally, for the measurement of this new model's productivity, ESC is used, and the strategic map and measurement indices are produced. The main contributions of this paper are showing a concrete model of ServiceScience and demonstrating this model can be extended to similar areas like are gas, water etc.

In this study, an Wireless Data Transmission Module for Large Spatial Structures has been investigated. An Wireless Data Transmission Mobule was designed with a Zigbee-based wireless communication function and a low-power, a variety of external interface. This was designed using RadioPulse Inc's MG2470-chip with a Zigbee-based wireless communication function, and Power Circuit was designed using Battery. The MG2470-chip is a true 2.4GHz system-on-chip (SoC) designed for low-power, low-cost applications based on the industry standards such as IEEE802.15.4 and RF4CE. The MG2470 involves 8-bit 8051 MCU with internal 64-KB flash memory and 6-KB SRAM. Accordingly, it is possible to development of an optimal firmware.

현재 와이파이가 지원되는 스마트폰 시장이 급격히 증가하면서 스마트 폰을 기반으로 하는 네트워크 콘텐츠 가 빠르게 보급되고 있다. 하지만, 아직까지 와이파이가 지원되지 않거나 블루투스 환경만을 제공하는 피처폰이나 기타 멀티미디어 기기 등에서는 네트워크 콘텐츠를 제공하기 힘든 환경이다. 본 논문에서는 블루투스, 와이파이 등의 기술보다도 저전력, 저가격, 사용의 용이성, 다채널, 브로드캐스팅을 지원하는 지그비 기술을 이용하였다. 근거리 네트워크 게임에 지그비 기술을 이용함으로써 다양한 형태의 네트워크 게임을 개발할 수 있을 것이다. 또한, 이를 이용한 다양한 무선 네트워크 컨텐츠의 개발을 기대할 수 있을 것이다.

지그비 모듈용 소형 PCB안테나를 30mm×8mm의 좁은 영역으로 제한된 공간에서 구현함과 동시에 안테나의 반사손실을 개선시키기 위하여, 기생소자로 접지면과 이격되는 도체를 가지는 미앤더 슬롯 안테나가 제안된다. 본 논문을 통해 설계되어 제작된 안테나의 공진주파수는 대략 2.44GHz이고, 대역폭은 113MHz(VSWR≤2)이다. 방사패턴은 동작주파수영역에서 다이폴 안테나의 방사특성과 거의 유사하고, 안테나의 효율 및 이득은 각각 60% 및 2.7dBi이상의 값을 가진다. 이러한 안테나의 모든 특성들은 지그비에 응용되기 위해 요구되어지는 규격을 모두 만족함을 알 수 있다. 본 논문이 제안하는 안테나의 타당성을 보여주기 위해 모의실험 결과 및 측정결과를 비교하여 제시하였다.
