The schedule management in construction project have been performed independently by two method, WBS base management and CBS based management, However, the integrated management model is needed according to efficiency of construction project management and introduction of new EVMS system of KOREA government. For this purpose, interworking database system is designed through efficient modeling of WBS based management data and CBS based management data and relation establishment between entities in this paper. WBS based management DB consists of 4 entities and CBS based management DB consists of 3 entity and one of the 4 WBS DB entities is used to play interworking role between WBS and CBS, Also, attributes of all entities are well defined so that data consistency, integrity and newest are guaranteed. The designed interworking database model was realized using Nex-Pert Pro and the efficiency of data interworking was proved.

This paper proposes an algorithm of address analysis for the next-generation networks. That is, we present integrated address analysis of the Numbering Plans of public telecommunication networks such as those of the ATM network. The purpose of implementing software for integrated address analysis is to actively and flexibly cope with a large change of information while operating the system and the network. By designing and implementing a database structure and an address analysis algorithm, interworking is possible among part (local) networks that each have a different Addressing Plan within an integrated network. Proposed relational model database structure has effect that do to manage address information of complicated network efficiently. Also, apply in real environment and proved excellency through interworking test to verify mechanism that propose.

The plant factory represents one of the future agricultural systems into which ubiquitous information technology (U-IT) is incorporated, including sensor networking, and helps minimize the influence of external experimental factors that constrain the use of existing greenhouse cultivation techniques. A plant factory's automated cultivation system does not merely provide convenience for crop cultivation, but also expandability as a platform that helps build a knowledge database based on its acquired information and develop education and other application services using the database. For the expansion of plant factory services, this study designed a plant factory interworking service (PFIS) which allows plant factories to share crop growth-related information efficiently among them and performed a test on the service and its implementation.

본 논문은 무선 인터넷 서비스를 제공하는 이동통신 망에서 동기식과 비동기식 IMT-2000서비스를 동시에 제공하는 통합 게이트웨이 시스템인 A-MiDAS(Advanced Mobile internet Data Access System)을 위한 데이터베이스 구성 방법에 관한 것이다. A-MiDAS시스템은 동기식 망의 PDSN 노드 역할과 비동기식 망에서의 GGSN 게이트웨이를 담당한다. 패킷에 대한 사용자 인스턴스로서의 세션 정보는 사용자가 패킷 통신을 하고자 할때, 시작부터 종료 시까지의 모든 과정에서 발생하는 유지 정보를 관리하여 각각의 인스턴스 항목간의 오버헤드를 줄이고 세션 정보의 관리를 용이하고, 검색에 따른 지연시간을 줄일 수 있어야 한다. 또한 전체 시스템의 상태를 관리함으로써 운용상에서 실시간 모니터링을 통한 사용자의 인터넷 서비스를 안정적이고 지속적으로 제공할 수 있다. 이에 본 논문에서는 GPRS망에서의 GGSN을 담당하는 게이트웨이 시스템 관점에서의 A-MiDAS시스템을 구축하는데 필요한 데이터베이스 구성 방법을 제시한다.

정보통신 기술의 발달로 자치단체에서 개별적으로 운영되던 업무별 단위시스템을 단일화 또는 연계하여 자료를 공동 활용하려는 노력이 계속되고 있다 하지만 타 시스템의 자료를 실시간으로 검색함에 있어 빠른 응답시간이 요구되며, 검색건수 증가에 따른 수행지연으로 인한 문제가 되고 있다. 따라서 본 논문에서는 검색 대상 자료를 본 시스템의 메모리에 상주시켜 연계자료에 대한 검색속도를 높이고 수행지연에 의한 병목현상을 해결할 수 있는 방안을 제시하였다.

The system of this paper designs and implements a used trading system that is commonly used on the Internet. In order to pursue local transactions based on location, we designed the system by dividing the region in consideration of the general characteristics of used transactions that are restricted by transactions through distance and location. To do this, I used MySQL as the database engine and I used PHP, an Internet server-based scripting language, for database interworking. Due to the characteristics of secondary transactions, information security and design of each product are considered.

The purpose of this paper, as a part of healthcare research, is to design and development Patient-aware System that will support EMR(Electronic Medical Record) in hospital. A mobile device-based system that can use database of existing EMR, replace existing paper-type chart, and identify patient fast and correctly was developed. To identify patient, RFID(Radio Frequency Identification) was used, and through interworking RFID and the system, it is possible to identify patient automatically. The developed system was tested in the test bed, and the possibility of faster diagnosis and treatment than existing paper-type chart was tested.

Lately big data processing is considered as an emerging issue. As a huge amount of data is generated, data processing capability is getting important. In processing big data, both Hadoop distributed file system and unstructured date processing-based NoSQL data store are getting a lot of attention. However, there still exists problems and inconvenience to use NoSQL. In case of low volume data, MapReduce of NoSQL normally consumes unnecessary processing time and requires relatively much more data retrieval time than RDBMS. In order to address the NoSQL problem, in this paper, an interworking scheme between NoSQL and the conventional RDBMS is proposed. The developed auto-mapping scheme enables to choose an appropriate database (NoSQL or RDBMS) depending on the amount of data, which results in fast search time. The experimental results for a specific data set shows that the database interworking scheme reduces data searching time by 35% at the maximum.

다양한 업무처리를 위한 인적정보들이 서면상의 기록 형태로 관리되고 있음으로써 정보갱신 및 이용을 위한 접근이 어려울 뿐 아니라 원격지에서의 정보관리 및 공유가 되지 않는 불편 때문에 다양한 정보의 활용 및 운영이 비효율적이다. 이에 본 연구에서는 학생정보를 데이터베이스화 시키고 ASP (Active Server Page)를 이용한 Web과 데이터베이스를 연동시켜 정보를 관리 및 공유함으로써 보다 나은 정보의 활용성과 보안성 그리고 공간 이용의 효율성을 제공 하고자 한다.
