The wastewater reclamation and reusing system has been rising as an alternative of water resource exhaustion that the whole world is experiencing. In order to be able to bring about improvement of the existing wastewater reclamation and reusing system, this research has developed of Conversion-Human Machine Interaction (C-HMI) based real-time control and monitoring system such as a sensor module and gate module, web monitoring system. This system was communication almost-error-free in various environment and situation. As a result, we have achieved our goal that has to doing work correctly as a sensor and gateway module that communication error is less than 0.2% throughout the embodied system and add that it can be easily controled and configured as an interface equipment to a complex sensor of water quality. According to this, the construction of a database capable of analyzing and assessing collection, storage and various elements of reliable water quality and flow rate data can be possible.

The ZigBee communication method, which is the most frequently applied to the LED lighting control system, has drawbacks of low-speed and low-capacity, and the communication failure possibility due to environmental influences is on the rise. Therefore, it is important to secure the communication reliability by applying an integrated interface with a wire-wireless dual-network. This paper developed a communication module, which has a platform converging and combining the ZigBee of USN environments with the PLC of power line communication environments, to implement a dualized communication interface system supporting the wire-wireless integrated protocol, and implemented a wire-wireless networking device and a control system software technology. As a result, it was automatically switched into the PLC communication within 4.4 seconds on average when there was an access failure in the ZigBee communication network, so a reliable communication network was built.

리눅스는 안정성의 검증과 유지관리 업체들의 성숙으로 그 사용자층이 급속히 증가하고 있으며, 이미 신규 네트워크서버시장에서는 MS를 추월하고 있다. 이제 리눅스는 일시적인 유행이 아니며 전 산업계에 걸쳐 급속도로 확산되고 있으며, 향후 가장 많이 쓰이게 될 운영체제로 성장할 것으로 예상된다. 이제는 대학에서 관련학과뿐만 아니라 전체 학생들을 대상으로 리눅스 교육을 실시하여야 할 필요가 있다. 하지만 다양한 교육이 끊임없이 진행되는 현실에서 리눅스 교육을 위해서 실습실을 독점한다는 것은 현실적으로 어려움이 많다. 이를 해결할 수 있는 교육방법이 가상머신 기반의 리눅스 교육이다. 가상머신은 이미 그 성능과 효율성이 입증되어 많은 연구ㆍ교육기관에서 사용되고 있다. 향후 각종 컴퓨터 관련 교육에 가상머신을 보다 적극적으로 활용하여 다양한 교육과정을 효율적으로 운영할 수 있어야 한다.

이운선(Un Seon Lee),박만곤(Man-Gon Park) 한국멀티미디어학회 2010 한국멀티미디어학회 학술발표논문집 Vol.2010 No.2
오늘날 심근경색 환자가 급속히 증가하고 있다. 하지만 목격자에 의한 심폐소생술 실시율은 극히 저조하여 심근경색 환자의 생존율이 매우 낮다. 심장마비 직후 4∼6분이 환자의 생사를 가르는 상황에서 심폐소생술을 위한 AED 빠른 탐색과 적용은 매우 중요하다. 본 논문에서는 GPS를 이용한 위치기반기술과 증강현실기술 그리고 모바일 애플리케이션기술을 활용하여 빠르고 쉽게 AED의 위치를 탐색할 수 있는 ‘AED 탐색 모바일 애플리케이션’을 제안하였다. 본 시스템을 개발하여 활용하면 심근경색 환자가 발생한 장소에서 최단거리의 AED를 탐색하여 환자에게 적용하여 환자의 생존율을 높일 수 있을 것이다.

국내 에너지의 30%이상이 조명부문에서 소비되고 있어서 그 소비량과 $CO_2$ 배출량은 점차적으로 늘어날 수밖에 없다. 이와 같은 상황에서 스마트그리드 기반의 전등 제어시스템 구축에는 중요한 의미가 있다. 결과적으로 오늘날 산업현장에서 사용되는 전력선망 통신모뎀과 응용 단말기들을 활용, 본 논문은 PC기반의 전력선망 통신 제어시스템을 구현해봄과 동시에 다양한 통신 테스트 장치 및 도구로 활용하는데 유용할 것이다. 실험을 위해서 사용되는 모뎀은 ZIC 프로토콜 기반의 플래넷 제품을 활용하고 응용프로그램은 랩뷰(LabView)를 사용한다. 그 결과는 주로 저속 전력선 통신에 의한 장치 제어에 초점이 맞추어져 있으며, 전력선 통신 실험을 위한 전력선 통신 테스트 장치로 각종 실험을 수행할 수 있다. More than 30% of energy in Korea was spent in lighting part and then the consumption level and $CO_2$ emission will be increase from now. In this like situation, control-system construction for street-lamp of a smart grid-based that it has important meaning. Nowadays as a result, as an trying to utilize using Power-line-network communication modem and application a terminal in industrial fields, in this paper, we are want to implement the Power-line-network communication control system of PC-based. Therefore it will be use varied communication test-equipment and tools through the system. For experimentation, using the MODEM was able to use Planet production of based on the ZIC protocol and then the application program use the LabView. The result is primarily focused on equipments control by the PLC, and that we are able to perform each test with PLC equipment for experiment it.

The HMI(Human-Machine Interation) equipment which means "communication" between humans and machines that is spreading of the society with information and communication technologies. The characteristic of the existing HMI can describes information transmission device of an one-way. In information society of the day, The information of interactive and convergence that interaction robot system is demanding that is developed more in many areas. For this reason, the system will be occured high cost or difficulty for system development. Therefore, in order to solve this problem, we have proposed system configuration using C-HMI engine in this paper. The proposed system configuration in this paper that is to develop various application system of interactive robot but that it can be applied to various fields.

This study was conducted to evaluate the effects of com distillers dried grain with soluble (DDGS) in American and Chinese on quality and amino acid of meat in finishing pigs. 120 pigs (Landrace$\times$Yorkshire$\times$Duroc, 64.50 kg average initial body weight) were used in 56 day growth assay. Dietary treatments were included CON (basal diet), ADS (basal diet + DDGS from American) and CDS (basal diet + DDGS from Chinese). The pigs were allotted into four pigs per pen with ten replicates per treatments by completely randomized design. Backfat thickness and lean percentage were not affected by treatment (p>0.05). For the meat color, redness was significantly increased in DDGS treatments compared to CON treatment (p<0.05). CDS treatment was higher than in ADS treatment (p<0.001). Water holding capacity was higher in CON and CDS treatments compared to ADS treatment (p<0.05). pH was greater in DDGS treatments than CON treatment (p<0.05), and ADS treatment was higher than in CON treatment (p<0.05). For the amino acid of meat, CDS treatment significantly increased their arginine, isoleucine, leucine and lysine compared to other treatments (p<0.05). DDGS treatment was higher than in CON treatment (p<0.001). Methinonine, phenylalanine, threonine and valine were significantly increased DDGS treatments than CON treatment (p<0.05). Cysteine was greater in CDS treatment than CON and ADS treatments (p<0.001). DDGS treatments was higher cysteine than in CON treatment (p<0.001). Proline significantly improved in CON treatment compared to CDS treatment (p<0.05). Tyrosine was greater in DDGS treatments than CON treatment (p<0.01). In conclusion, redness and amino acids of meat were affected by DDGS treatments.
