A software configuration management(SCM) is essential for processing large scale project. The scope of SCM involves each developer's work space management, software building management, and development process control as wet] as version control. In this paper we focus on what parts should be controlled systematically for the optimized software build that is an important part of the SCM. We also analyze that to increase the efficiency of software build, what kind of configuration management information should be reported. Based on the analysis, we have actually designed and implemented a new reporting system and evaluated it. The evaluation includes comparative evaluation in efficiency based on the analysis about the related functions provided by existing tools and some additional qualitative evaluation through the questionnaires from stakeholders.

MPEG-21 has identified the need fur Event Reporting in its vision for an interoperable multimedia framework. Event Reporting is required within the MPEG-21 multimedia framework in order to provide a standardized means for sharing information about Events amongst Peers and Users. Such Events relate to Digital Items and/or Peers that interact with them. Arising from an each Event, there is the opportunity to describe what occurred. However, there are a number of difficulties in providing an accurate report about an Event. Different observers of the Event may have vastly different perspectives, needs, and focuses. They may emphasize certain elements to the detriment of others, or they may describe an Event in a way that others may find confusing. In this paper, we design how to express Event Reporting message structure and system architecture in compliance with ISO/IEC 21000-15. And we implement the system for MPEG-21 Event Reporting service.

Recently, the quality of the incident of school violence is getting worse and the frequency of its occurrence is gradually increasing. One of the biggest reasons that violence in schools does not reduce is because the attitude that they mean to hide damage from the violence, thus the improvement of such conditions enables school violence to decrease in the short-term effect. This study designed an intelligent reporting platform to prevent additional violence and victim's suicide, by related agencies and parents reporting the circumstance of school violence real-time, as both victims and attackers register real-time troubles anonymously, at any time, anywhere, then are provided 1:1 counseling and customized services, and all contents of the counseling are accumulated in the intelligent reporting platform.

MPEG-21 멀티미디어 프레임워크의 주요 기술 중 하나인 이벤트 리포팅은 MPEG-21 내에서 사용자, 피어, 디지털아이템 사이에서 발생하는 모든 보고 가능한 이벤트에 대한 정보를 공유하기 위한 표준적인 측정 방법과 인터페이스를 제공한다는 점에서 그 중요성을 가진다. 현재 MPEG을 중심으로 MPEG-21 이벤트 리포팅에 대한 연구가 진행되고 있으나 이를 구현한 예가 극히 드물다. 본 논문은 MPEG-21의 이벤트 리포팅 표준 기술을 바탕으로 이벤트 리포트 요구 생성 도구의 설계 및 구현 그리고 구현 결과에 대해 논하였다. 이벤트 리포트 요구 생성 도구는 메인 프레임, 입력 다이얼로그, 그리고 생성 프로세스로 구성되어 있다. 이벤트 리포트 요구의 표현언어는 XML이며 XML 표준 문법과 이벤트 리포트 요구 디지털 아이템 구조에 맞게 생성되도록 설계되었다.

데이터베이스에 저장된 수많은 자료들을 사용자의 질의에 맞추어 웹상에서 표현해주는 것이 바로 리포팅 툴의 역할이다. 그에 관한 연구들로 BBQ(Blended Browsing and Querying), EASY BASE, QURSED(Querying and Reporting Semistructured Data)와 같은 여러 리포팅 툴들이 상용화되어 있다. 하지만 사용자가 보다 쉽고 직관적으로 XML 문서를 작성하고 관리할 수 있는 툴들은 미흡한 것이 사실이다. 이 논문에서는 XML과 XSL문서를 각각 그룹핑하고 직관적인 구조로 표현 해주며 사용자의 관점에 맞추어 XQuery를 지원하는 시스템을 설계 구현하였다.

Database query and reporting tools, OLAP tools and data mining tools are typical front-end tools in Business Intelligence environment which is able to support gathering, consolidating and analyzing data produced from business operation activities and provide access to the result to enterprise's users. Traditional reporting tools have an advantage of creating sophisticated dynamic reports including SQL query result sets, which look like documents produced by word processors, and publishing the reports to the Web environment, but data source for the tools is limited to RDBMS. On the other hand, OLAP tools and data mining tools have an advantage of providing powerful information analysis functions on each own way, but built-in visualization components for analysis results are limited to tables or some charts. Thus, this paper presents a system that integrates three typical front-end tools to complement one another for BI environment. Traditional reporting tools only have a query editor for generating SQL statements to bring data from RDBMS. However, the reporting tool presented by this paper can extract data also from OLAP and data mining servers, because editors for OLAP and data mining query requests are added into this tool. Traditional systems produce all documents in the server side. This structure enables reporting tools to avoid repetitive process to generate documents, when many clients intend to access the same dynamic document. But, because this system targets that a few users generate documents for data analysis, this tool generates documents at the client side. Therefore, the tool has a processing mechanism to deal with a number of data despite the limited memory capacity of the report viewer in the client side. Also, this reporting tool has data structure for integrating data from three kinds of data sources into one document. Finally, most of traditional front-end tools for BI are dependent on data source architecture from specific vendor. To overcome the problem, this system uses XMLA that is a protocol based on web service to access to data sources for OLAP and data mining services from various vendors.

Due to the application-specific nature of wireless sensor networks, the sensitivity to such a requirement as data reporting latency may vary depending on the type of applications, thus requiring application-specific algorithm and protocol design paradigms which help us to maximize energy conservation and thus the network lifetime. In this paper, we implement and evaluate a novel delay-adaptive sensor scheduling scheme for energy-saving data gathering which is based on a two phase clustering (TPC), in wireless sensor networks. The TPC is implemented on sensor Mote hardwares. With the help of TPC implemented, sensors selectively use direct links for control and forwarding time critical sensed data and relay links for data forwarding based on the user delay constraints given. Implementation study shows that TPC helps the sensors to increase a significant amount of energy while collecting sensed data from sensors in a real environment.

Cell planning, which determines the cell structure for location management of mobile terminals in mobile communications, has been dealt with as an important research task to determine network performance. Among the factors influencing the cell structure planning in mobile communication, the signal cost for location management plays the most important role. In this paper, we propose an optimization algorithm that minimizes the location management cost of all the cells used to plan the cell structure in the network with reporting cell structure in mobile communication. The proposed algorithm uses a Tabu search algorithm, which is a meta-heuristic algorithm, and the proposed algorithm proposes a new neighborhood generation method to obtain a result close to the optimal solution. In order to evaluate the performance of the proposed algorithm, the simulation was performed in terms of location management cost and algorithm execution time. The evaluation results show that the proposed algorithm outperforms the existing genetic algorithm and simulated annealing.

It has been increased to use the SAN with increasing the size of storage device. In this paper, we design and implement a backup system to support the tape and disk based backup with devices and media in SAN cluster. Our backup system provides device and media management for efficiently managing a number of devices and media in SAN cluster. It also supports script management to process an additional tasks requested by clients and monitoring to control and manage tasks in execution. In addition, it supports reporting to offer backup and restore information to clients.

In this study, we suggest the effective storage structure and management method for XML-based electrocardiography(ECG) data to support the interoperability between medical information systems, and implement the metadata system of ECG data providing the web-based information service. ECG matadata management system include functions for storing and managing as well as reporting PDF service of ECG data. We analyzed a characteristics of the data and access patterns for XML-based ECG and then used the non-partitioning storing method and indexing the extracted metadata from the HL7 aECC for supporting the quick search. We, using the template mechanism, converts the XML-based results data into various formats in order to provide services of the ECG reporting.
