Collaborative product commerce (CPC) supports a collaboration that a global enterprise and customer related to life cycle of product share product information and a collaboration process for the collaboration, and integrating applications. In this paper, we use common data schema in order to solve a interoperability problem about shared product information between enterprises. And we map to common data schema from each other different data format. Therefore we implement CPC Adaptor in order to integrate distributed product information.

J2EE(JavaTM 2 Platform, Enterprise Edition)의 클라이언트 애플리케이션, 웹 컴포넌트, Enterprise JavaBeans 컴포넌트와 같은 앤터프라이즈 애플리케이션은 개발된 후 컨테이너에 배치되어 실행된다. 이러한 앤터프라이즈 애플리케이션(enterprise application)은 다양한 EIS(Enterprise Information System)에 접근하여 관련된 기능과 데이터를 사용할 필요가 있다. J2EE 커넥터 아키텍처(Connector Architecture)는 J2EE 플랫폼을 다양한 EIS와 연결하기 위한 표준을 정의하는 API 이며, 각 EIS 벤더는 이러한 커넥터 아키텍처의 설계서를 따르는 EISF의 시스템 레벨 소프트웨어 드라이버인 표준 리소스 어댑터(Resource Adaptor)를 제공한다. 커넥터 아키텍처를 구현한 리소스 어댑터를 사용함으로써 특정 벤더의 J2EE 플랫폼에 종속되지 않도록 EIS를 통합할 수 있다. 본 논문에서는 이러한 J2EE 커넥터 아키텍처를 구현한 리소스 어댑터를 애플리케이션 서버를 배치하기 위하여 배치기가 수행해야 하는 배치 단계를 크게 네 단계로 구분하고, 배치구성 활동을 다섯 가지로 분류 및 정의한다,

In order to drive motor control system precisely, the motor is to be controlled by mmfs and current with sinusoidal waveforms. In this paper the Delta Modulation (DM) Technique is used for generating PWM pulse with sinusoidal waveform. However the motor currents yet contain odd harmonics due to leakage inductances, speed and exitation. To reduce harmonics, the parameter adaptive control method is introduced. That is, Req.C parameter of Delta Modulator is controlled adaptively by parameter adaptor. The adaptive signal is achieved by the difference between motor current and reference waveform, and this signal is converted to the voltage commend signal by adaptive mechanism. The test reslts show that this system is operated smoothly over a wide range of motor speed and motor current is controlled to be sinusoidal waveform adaptively.

A disk photo sensor system was constructed and installed on engine for the crank angle measurement. Statically measured TDC crank angle data were compared with those obtained from engine motoring. Two groups of cylinder pressure data were compared each other, one measured by pressure transducer mounted flush on the combustion chamber and the other obtained with the help of spark plug type adaptor. A simple analysis on the gas flow in the spark plug type pressure transducer displayed reasonably good agreement with those from engine motoring tests. In various firing tests, the IMERs obtained from the spark plug type pressure transducer turned out to be higher than those from the flush mounted one at low engine speed while those two were nearly the same at high engine speed. As the engine load decreased the relative difference in IMEP measurement between the two types tended to be enlarged.

The adaptor protein (AP) complexes are involved in membrane transport of many proteins. There are 3 AP complexes in C. elegans unlike mammals that have four. To study the biological functions of the AP-3 complexes of C. elegans, we sought homologues of the mouse and human genes that encode subunits of the AP-3 complexes by screening C. elegans genomic and EST sequences. We identified single copies of homologues of the ${\mu}3$, ${\sigma}3$, ${\beta}3$ and ${\delta}$ genes. The medium chain of AP-3 is encoded by a single gene in C. elegans but two different genes in mammals. Since there are no known mutations in these genes in C. elegans, we performed RNAi to assess their functions in development. RNAi of each of the genes caused embryonic and larval lethal phenotypes. APM-3 is expressed in most cells, particularly strongly in spermatheca and vulva. We conclude that the products of the C. elegans ${\mu}3$, ${\sigma}3$, ${\beta}3$ and d genes are essential for embryogenesis and larval development.

A multimedia remote ultrasound image transfer system for tole-medical services was implemented. The image data of the ultrasound scanner system of the slave is compressed using image compression system. It is transferred to the master PC via ISDN UNI(User-Network Interface) and decompressd by image decompression system. The total system is composed of three parts; first, the image capture card which transfers bidirection- al data between ultrasound scanner system and PC, second, image compression and decompression card, finally, ISDN TA(Terminal Adaptor) card for transferring the image. This system has a easy user interface because it is executed on the basis of MS-WINDOWS. So it is capable of serving medical services at a remote place.

In this paper, to realize the network management function in automated manufacturing network Mini-MAP, the network management requirements are analyzed and the network management system is implemented on the basis of this analysis. The implemented management system which has both local management and remote management mechanism is considered as a single domain on the Mini-MAP network. Here, the remote management functions consist of network status, monitoring and remote operations and the local management functions have parameter display and network self testing. The MAP network controller is designed according to the MAP version 3.0 specifications and IEEE 802 standards. the operations of network management system are certified througth the test environments which consists of the implemented network adaptor and softwares for Mini-MAP.

As a method of measure the absorbing characteristics of microwave absorber, the various microwave measuring method can be used fundamentally. There is, however, a big problem in measuring errors, since the wavelength of microwave such as used for radar is very short. Therefore, this research aimed to design and fabricate a converting adaptor of $20mm^{\phi}$ coaxial tube from a Type-N connector to $20mm^{\phi}$ coaxial tube and to use it for evaluating absorption characteristics of microwave absorber. Furthermore, the measurements of absorbing characteristics and material constants have been performed and review, which were carried out by using the coaxial tube and by using rectangular waveguide, respective. As a result, the validity of the proposed measuring method has been confirmed.

유비쿼터스 환경에서의 일반 사용자를 위한 흠 네트워크의 실현은 다양한 가전 제품군의 홈 네트워크 미들웨어들이 표준화되고 상용 장비에도 장착이 되어 실용화된다. 흠 네트워크 환경에서 UpnP (Universal Plug and P1ay) HAVI (Home audio/video interoperability) HNCP(Home Network Control Protocol)등과 같은 개별 단체 표준 미들웨어들을 탑재하고 있는 이종 정보가전기기들 간의 상호연동성을 제공하고，홈 네트워크 미들웨어들을 쉽게 수용하기 위해서 Universal Middleware Bridge 시스템 규격을 ITA 표준안에서 정의하였다. TTA의 Universal Middleware Bridge(UMB)를 표준화로 제안되고 있는 범용 미들웨어 브릿지(UMB)는，SOAP/HTTP 기반의 UMB 메시지 전송/수신 기능을 가지고 있는 Universal Middleware Bridge Core(UMB-C)와 접속 설정 기능과 UMB 메시지를 수신，해석，생성，전송하는 기능을 가지고 있는 Universal Middleware Bridge Adaptor(UMB-A)로 구성 된다. UMB 메시지는 3가지 범주로 분류된 메커니즘이 있다. 첫 번째는 미들혜어의 접속과 해제에 관련된 메커니즘이고，두 번째는 장치 접속/해제에 관한 메커니즘이며，세 번째는 장치에 대한 제어/감시/이벤트에 관한 메커니즘이 있다. 본 논문에서는 미들웨어 운영 메커니즘에 서비스 품질 패키지，경고 메시지에 대한 메커니즘을 추가 설계하였다.
