In this paper, You can design drawing to safekeep and manage equipments in order to utilize efficiently by making use of Visio, and can convert stored data into Office data after inputting user attributes of each equipment. that means that you can analyze each data by using functions of Excel after changing Visio safe attributes into Excel data and XML data, and control and utilize data effectively by converting XML data into DB ones. Additionally. you can use on deliveration of useful information on shopping mall. At last, we present how to share and utilize transformed equipments on the web by designing and making and transforming Data type for good management of equipments of computers existed in university.

The physical attributes of a computer, such as processor speed, size and access time of memory, and I/O bandwidth, are fixed when the computer is delivered to the user. Under these conditions, the performance of a multi-process system where multiple processes share various resources can be enhanced by monitoring and controlling the relationship between the user processes and the system resources. This paper applies object oriented concept to the performance management and suggests a standard for the management. Resource managers and user processes are defined as managed object and a performance manager is defined as a managing object. A protocol between the user processes and performance manager is designed and attributes and methods of the objects are also defined. Through the standardization, the user processes and the performance manager can be developed independently and the system's performance can also be collectively managed.

WebDAV is a protocol to support collaboration among the workers in geographically distant locations through the Internet. WebDAV extends the web communication protocol HTTP/1.1 to provide a standard infrastructure for supporting asynchronous collaboration for various contents across the Internet. To provide the WebDAV functionality in legacy applications such as web-based collaborative systems or document management systems, those systems need to be implemented additionally to handle the WebDAV methods and headers information. In this paper, we developed an Apache-based WebDAV server, named DAVinci(WebDAV Is New Collaborative web-authoring Innovation)which supports the WebDAV specification. DAVinci was implemented as a form of service provider on a mod_dav Apache module. Mod_day, which is an Apache module, is an open source module to provide WebDAV capabilities in an Apache web server. We used a file system for storing resources and the PostgreSQL database for their properties. In addition, the system provides a consistency manager to guarantee that both resources and properties are maintained without inconsistency between resources and their properties.

For social demand and technological development, systematic private information management and security guidance have been enhanced; however, the issue of leakage and invasion of private information is shown in many ways. In the management of such private information, the issue of how to protect such information is one of the sensitive key elements. As a criterion to decide the management policy of each property information consisting of private information, this article suggests Dynamic-Security-Level-Measurement for property information. DSLM adopts the variable characteristics of property information as the element of measurement. By applying this method, it is possible to provide information management functions to cope with the changes of each property information security level of an individual actively. It is expected that this will improve the security of previous information management methods even more and also contribute to the improvement of security in integrated systems such as the integrated ID management system and electronic wallet.

The ontology has been used widely in recent years with its aim to accumulate knowledge that machine can comprehend. We believe that machine can manage and analyze information on its own using the ontology. In this paper, we propose an algorithm that allows us to extract properties of ontology instances from structured information already existing in web documents. In particular, by stratification of the domain knowledge that is composed of property information, we were able to make the algorithm better and improve the quality of extraction results. In our experiments with 20 thousands targeted documents, we were able to extract property information with 83% confidence.

In this paper, we propose an FA-RBAC (FA-RBAC) model based on flexible properties. This model is assigned attribute-role-centric, making it easy to manage objects, as efficient as access control, and as the network environment changes, it can provide flexible access control. In addition, fine-grained permissions and simple access control can be achieved while balancing the advantages and disadvantages of the RBAC and ABAC models, reducing the number of access control rules by combining static attribute-based roles and dynamic attribute-based rules, and verifying the validity and performance benefits of the proposed model through comparison analysis and simulation.

최근 고객관리 서비스는 사용자의 환경 및 특성까지 분석하여 개인에게 가장 적합한 서비스를 제공하는 형태로 변화하고 있다. 하지만 기존 고객관리시스템은 회원 가입 시 작성하는 정보 이외에 추가적으로 고객에 관한 정보를 얻기 위한 방법이 한정적이다. 이러한 기존의 고객관리 시스템은 고객의 성향에 따른 다양한 형태의 서비스를 제공하지 못하고 있다. 본 연구에서는 무선 통신 방법인 NFC(Near Field Communication)를 이용하여 고객의 성향을 신속하게 파악하며 분석할 수 있는 고객관리 시스템을 개발 제안한다. 제안된 시스템의 특징은 데이터의 처리 및 전송 경로가 사용자정보를 직접 서버로 전송하게 되며, 정보를 관리 서버에서 범주별로 분류하여 속성 단위로 가중치를 적용하여 분해하는 기능을 제공한다. 개발된 서버에서는 범주별로 규정되어 있는 속성정보에 대해 가중치와 저장된 사용자 정보를 제공된 알고리즘에 따라 상황인식기반으로 내용을 분석하게 되고, 분석된 사용자 정보들의 결과 값이 가장 높은 값을 가진 범주를 사용자의 특성으로 제공한다. 본 시스템으로부터 추출된 예측된 값은 사용정보를 수신할 때마다 갱신이 가능함으로 개발된 시스템은 사용자의 동향을 이용한 서비스를 온라인으로 제공할 수 있게 된다.

There is a wide variety of data quality attributes such as the ones proposed by the ISO/IEC organization and also by many other domestic and international institutions. However, it takes considerable time and costs to apply those criteria and guidelines to real environment. Therefore, it needs to define data quality evaluation attributes which are easily applicable and are not influenced by organizational environment limitations. The purpose of this paper is to derive data quality attributes and order of their priorities based on customer requirements for managing the process systematically and evaluating the data quantitatively. This study identifies the customer cognitive constructs of data quality attributes using the RGT(Repertory Grid Technique) based on a Korean quality standard model (DQC-M). Also the correlation analysis on the identified constructs is conducted, and the evaluation attributes is prioritized and ranked using the AHP. As the results of this paper, the consistent system, the accurate data, the efficient environment, the flexible management, and the continuous improvement are derived at the first level of the data quality evaluation attributes. Also, Control Compliance(13%), Regulatory Compliance(10%), Requirement Completeness(9.6%), Accuracy(8.4%), and Traceability(6.8%) are ranked on the top 5 of the 19 attributes in the second level.
