Currently, the existing order communication softwares are composed of database management characterized packages. Each indivisual module of the software is developer based on the text type environment which is inner data-process centered Therefore, actually these types of softwares do not consider the variety of the strange situation and the operating condition in real medical sites properly. In this paper, as integrating or distributing the computing system procedures as the common and particular field of the classified task group, we developed the system which simplifies the correction and the transplantation due to the variety of the order type and commucation processing.

현재 사용자에게 제공되고 있는 지리정보시스템(GIS : Geometry Information Systems) 소프트웨어들은 패키지 형태로 제공되어 구축 비용 및 다양만 사용자 요구 사망을 충족시키기에 많은 어려움을 가지고 있다. 또한 개발된 결과물은 다른 분야로의 확장이나 재사용하기가 어렵게 되어 있다. 본 논문에서는, OGC(Open GIS COnsortium) 의 개방형 지리정보 시스템서비스 아키텍쳐에 기반을 둔 지리정보시스템 서비스 컨포넌트의 설계 및 구현에 대하여 서술한다. 각 서비스 컴포넌트는 단위 기능을 컴포넌트 형태로 제공함으로써 구축 비용 및 다양한 사양한 요구사항을 효율적으로 충족시킬 수 있다. 또한 컴포넌트 소프트웨어의 특징인 재사용성을 충족하므로 향후 유지보수나 기능확장에 많은 장점을 가질 수 있다.

사용자에게 제공되고 있는 대부분의 시간 지리 정보 시스템은 소프트웨어 형태로 패키지화하여 제공되므로 과다한 구축비용과 재사용성의 문제점을 가지고 있다. 그리고 시간 지리 정보 시스템은 복잡하며 대용량인 특성을 가진 시공간 데이터를 처리해야만 한다. 따라서 시공간 데이터의 효율적인 관리 및 재사용성을 위해서 소프트웨어 부품화물 제공하는 컴포넌트 개발 방법론을 사용해야하며 시공간 데이터에 빠르게 접근하기 위한 인덱스 구조가 필요하다. 이 논문에서는 시공간 데이터를 효율적으로 관리하기 위하여 4차원 시공간 객체에 대한 인덱스를 컴포넌트 개발 방법론을 적용하여 설계하였다. 그리고 다차원 인덱스를 이용하는 4D 데이터 제공자를 COM 기반의 OLE DB 인터페이스를 이용하여 구현하고 성능을 평가하였다.

In this paper, we developed an e-loaming contents for C programming language using Linux and open source software, not using commercial integrated development tool like Microsoft's Visual Studio. In most programming language courses, students study or practice the programming language by editing source code compiling and running the executable code by commercial software like Visual Studio which installed on each PC. This way of learning has some difficulties in total cost of purchasing software and using other PCs which donot have proper software installed. To overcome this situation and enable loaming anywhere, with any device, at anytime, we propose a way of utilizing Linux and open source software in Web-based learning environment. In this environment students can input their source code on the form of broweser and get the result instantly from the server.

In this work, a mathematical modeling of SAW coupled mode in SAW resonator filter, which is very useful in analyzing the characteristics of periodic electrode structure such as SAW reflective array and inter-digital transducers. was considered by mathematical analytic approach. The design and simulation method for resonator filter was also proposed by equivalent transduction matrix using this mathematical modeling. In order for a designer to simulate, and to design the coupled mode SAW resonator filters effectively that could be applied to mobile communication system, a design simulator for coupled mode filter was implemented by graphic user interface, and it was investigated by designing and analyzing practical SAW coupled mode resonator filter from a view point of application of this simulator.

The purpose of this study is to examine the factors influencing performance of change control, management review and flexibility in the software company with innovativeness. This model tests various theoretical research hypotheses relating to performance of software company, change control, management review, flexibility and innovativeness. Valid 100 questionnaires have been collected within two months of 2010. EXCEL, Smart PLS(Partial Least Square) 2.0 and SPSS 15.0 have been utilized for deriving the study results. The results of hypothesis testing are as follows. First, change control and management review positively influences flexibility. Second, flexibility positively influence performance of software company. Finally, change control to flexibility for low group of innovativeness is significantly larger than those for high group of innovativeness. But management review to flexibility for high group of innovativeness is significantly larger than those for low group of innovativeness. The results of this study will provide various implications on performance of software company.

Being widely used for preparation of geographic maps in the field of earth sciences, Generic Mapping Tools (GMT) is difficult to understand the contents for user, and not working well with Microsoft (MS) Window PC. By utilizing R package, 'GEOmap', we can do mapping work at MS window PC with commands easier than those of GMT. In addition, the R commands offer interactive help. Here we introduce brief feature of 'GEOmap', and illustrate the procedure for preparing tomographic maps with an example.

TINA is the Open Networking Architecture which as newly introduced software architecture shares the network managements and the service managements on the Distributed Processing Environment. In this paper, based on the concepts and principles defined up to now, we implement and test the CM(Connection Management) Package included in CM which is one of the six functional areas into which TINA Management Architecture is devided. Before the implementation we learn the basic concepts accepted by the four architectures in TINA, and medelling concept of the CM. The interfaces of eaxh information objects explain the functions of computational objects implemented, and the message flows among the computational objects show the connection setup and release procedures.

Biplot is a modern graphical methodology allowing for the projection of high-dimensional data to a low-dimensional subspace that is rich in information on variation in the data, correlation among variables as well as class separation. For the construction of biplots, we use a BiplotGUI package in a free statistical software R with increasing popularity. Moreover, using data from questionnaires given to Chonbuk National University freshmen in 2009, the relationship between career goals and career maturity are studied by applying the biplot method.

In this paper, we present design and developing method for EMS(environment monitoring system) of micro data center. This developing EMS monitors operating environment of micro data center and analyze sensing data through IoT(Internet of things) sensors in real time. Firstly we present configuration method of IoT sensing package and design method EMS hardware platform. Secondly we design data collector software for data collection of IoT sensor with different protocol and develop monitoring software of EMS. The data collector software consists of sensor collector module and collector manager module. Also we design EMS software which has micro service architecture structural style and component based business logic.
