Recently, the data model in stream data environment has massive, continuous, and infinity properties. However the stream data processing like query process or data analysis is conducted using a limited capacity of disk or memory. In these environment, the traditional frequent pattern discovery on transaction database can be performed because it is difficult to manage the information continuously whether a continuous stream data is the frequent item or not. In this paper, we propose the method which we are able to predict the frequent items using the regression model on continuous stream data environment. We can use as a prediction model on indefinite items by constructing the regression model on stream data. We will show that the proposed method is able to be efficiently used on stream data environment through a variety of experiments.

This study was to determine the effectiveness of oral decontamination with chlorhexidine for prevention of ventilator associated pneumonia(VAP) using meta-analysis. MEDLINE, Pubmed, Cochrane library CINAHL and RISS, Koreamed, KISS databases were searched. key words used 'Ventilator-associated pneumonia', 'oral care', 'chlorhexidine' Ninety studies met the inclusion criteria for the meta-analysis. data were analyzed by the Revman 5.3 program of cochrane library and assessed for methodological quality using RoB (The Cochrane's Risk of Bias). The main findings of the current study suggest that chlorhexidine oral care have a positive impact on Ventilator associated pneumonia.

고령화는 국가사회적 최상위 현안문제 (National Agenda)의 하나로, 최근 출산률 저하와 수명 연장에 따라 점차 심화되고 있다. 이는 이미 퇴행성 척추 질환 및 관련 수술이 큰 폭으로 증가되는 현상으로 나타나고 있다. 따라서 고령화 사회를 대비하고 노령 인구의 삶의 질 향상을 위해, 노령 척추 질환에 대한 적절한 진단과 치료, 재활에 도움을 줄 수 있는 가상 척추의 개발이 절실히 요구된다. 본 논문에서는 국가문제해경형 연구사업(NAP)의 일환으로 가상 척추의 기반이 될 인체 척추 정보 데이터베이스를 구축하고 관리하는 시스템을 소개한다.

XMLis that XML developers in client application data text base format that can express and deliver and exchange structured data to display and manufacture. Store Spatial XML to RDBMS actually and is using to useful data that do geography information there is many interests in utilization that Spatial XML including Spatial information does it appearing to this XML Wish to search Spatial XML about data that is stored to RDBMS using Spatial XQuery to ask a question in this paper and embody Spatial XML Generator algorithm that draw information in RDBMS in XML form through Spatial XML Generator also.

사회 고령화에 따라 노화와 동반하여 나타나는 퇴행성 질환의 정복을 통한 삶의 질 확보가 시급한 것으로 나타났다. 특히, 노인성 척추 질환은 매년 국민의료 부담 및 경제 손실을 큰 폭으로 증가시키고 있으며, 이 질환은 개별 환자에 최적화된 척추의 수술 및 재활 치료를 요구한다. 최근 노령화 사회가 급속히 진행되면서 일반인들은 다양한 기관에서 제공하는 의학정보 서비스를 통해 많은 의학정보를 활용하고 있다. 하지만, 기존 의학정보 서비스들을 통해 다양하고 풍부한 정보를 얻기 위해서는 많은 시간과 노력을 투자해야 하며, 일부 서비스는 일반인들이 이해하기 어려운 정보를 서비스하기도 한다. 그래서 본 논문에서는 한국과학기술정보연구원에서 구축한 e-Spine을 기반으로 사용자 수준별 척추 질환 정보 온톨로지를 구축하고, 이를 기반으로 PC, Tablet PC, Mobile Phone에서 활용 가능한 교육 시스템을 개발했다. 마지막으로 본 논문에서 개발한 척추 질환 교육 시스템은 일반인들에게는 좀 더 쉬운 정보 제공을 목적으로, 전공의들에게는 좀 더 풍부한 정보 제공을 목적으로 활용됨으로써, 차후 노인성 척추 질환 대응 서비스의 하나로 자리매김 할 것으로 기대한다.

There have been many considerations to develop new content services that integrate a variety of contents databases being already constructed and then produce new content services which are more valuable than existing services in many applications such as Internet portal, EC, and CRM. By doing the above thing, the burden of searching databases to access interesting databases and service applications can be reduced and the database availability of users is also enhanced through a single view integrating multiple contents database. This paper presents implementation details of the query processing system that is a core component of the database integration system, which can construct a virtual database that integrates databases being managed by multiple heterogeneous database systems using XML data model and support a quay facility on the integrated database.

Radio Frequency Identification(RFID) technology is set to play an essential role in object tracking or supply chain management systems. New challenges for RFID data management are needed in the RFID applications. RFID data are generated quickly and automatically, and can be used for object tracking, or for real-time monitoring. These applications are mostly associated with the timestamps when the events happen. In this paper, we propose a temporal RFID data model to maintain the history of events and state changes and to monitor the states of RFID objects. Also we propose data filtering method of non active data based on temporal RFID data model. This data model involves essential basic operations for RFID data. We show increased query performance through the data filtering method of non active data.

In this paper, we suggests a algorithms of recognizing the disease region by extracting particular organ from medical image. This method can extract liver region in spite of input image including many organs and charged format by using multi-threshold of feed-back-structure for segmentation liver region, and suggest the recognition of disease region in extracted liver, using multi-neural network structured by RBF and BP, overcoming the defect of single-neural network. The algorithm in this paper is proficient in adaptation for a multi form change of input medical image. This algorithm can be used at tole-medicine through automatic recognition after recognizing of the disease region by real-tire medical Image.

We recognize call centers as a interface frequently interacting with clients, and as the first portal of enterprises promoting customer satisfaction and increasing the rate of customer maintenance. The importance of service quality in call centers is gradually enlarged, as criteria for competitive power of enterprises, and the first-line interface of communications with customers in operating method and business management. Also, Enhancing service quality is the first task of both the management and telemarketers in order to adapt to the customer's requirement level. The curriculum for telemarketer education is not established or standardized within the country yet. We must therefore study on it as soon as possible, though it has a short history and insufficient theoretics. In this paper, we descirbe the development of a formal telemarketer education program in call centers included the result that analyze existing educational programs, and the opinion of call centers.

Efficient reasoning has become important for improving the performance of ontology systems as the size of ontology grows. In this paper, we introduce a method that efficiently performs reasoning of RDFS entailment rules (i.e., rdfs7 and rdfs9 rules) and OWL inverse rule using views in the DBMS-based triple sotre. Reasoning is performed by replacing reasoning rules with the corresponding view definition and storing RDF triples into the structured triple tables. When processing queries, the views is referred instead of original tables. In this way, we can reduce the time needed for reasoning and also obtain the space-efficiency of the triple store.
