Many large organizations that have allocated resources to Data Administration(DA) have DA-context meta data mining. Also meta data is an interesting topic in the data warehouse world. This conceptual view gradually cleared up, and recently we have been talking more confidently about the back-room and front-room meta data. We describe the processes and problems that characterize the general architecture of s meta data mining system to do improve management efficiency that require further research and development.

In general, weapon system design/configuration data consist of system structure information which is linked to Part information, documents and drawings. For configuration management, version and revision control are necessary and access control of users to information should be managed for information security. Configuration data of weapon systems have various kinds of different meta data which are contained in the structure as well as attributes of parts and documents information. If neutral types of meta data models be used for building configuration management system, they can be applied to many different kinds of weapon systems with a little customization. In this paper, five meta data models are supposed and implementation results of them by using CBD(component based design) methodology are presented.

최근 기업의 시스템들은 데이터 공유와 협업을 위해 통합의 필요성을 제기하고 있다. 통합을 위한 방법론으로 서비스 통합을 위한 서비스 지향 아키텍처와 서비스에 사용되는 데이터의 통합을 위한 마스터 데이터가 등장했다. 본 논문은 BP(Business Process)를 효율적으로 운용하기 위한 방안을 제시한다. 우리는 BP를 지원하기 위한 지식 저장소로 XMDR(eXtended Meta Data Registry)과 이를 운용하기 위한 데이터 허브를 구성한다. XMDR은 데이터 통합을 위한 MDM(Master Data Management)을 관리하고, 데이터 간의 이질성을 해결하고, 업무 간의 연관관계를 효율적으로 제공한다. 이것은 MDR(Meta Data Registry), 온톨로지, BR(Business Relations)으로 구성된다. MDR은 구조적 이질성을 해결하기 위한 메타 데이터간의 관계성을 기술한다. 온톨로지는 의미적 이질성과 데이터 간의 관계성을 기술한다. BR은 업무 간의 관계성을 기술한다. XMDR 데이터 허브는 마스터 데이터의 관리를 지원하고, 프로세스 간의 상호작용을 효율적으로 지원할 수 있다.

Purpose: This study aimed to test a hypothetical model of Korean nurses' patient safety management activities using meta-analytic path analysis. Methods: A systematic review, meta-analysis, and meta-analytic path analysis were conducted following the PRISMA and MOOSE guidelines. Seventy-four studies for the meta-analysis and 92 for the meta-analytic path analysis were included. The R software program (Version 3.6.3) was used for data analysis. Results: Four variables out of 49 relevant variables were selected in the meta-analysis. These four variables showed large effect sizes (ESr = .54) or median effect sizes (ESr = .33~.40) with the highest k (number of studies) in the individual, job, and organizational categories. The hypothetical model for the meta-analytic path analysis was established using these variables and patient safety management activities. Twelve hypothetical paths were set and tested. Finally, the perception of the importance of patient safety management and patient safety competency directly affected patient safety management activities. In addition, self-efficacy, the perception of the importance of patient safety management, patient safety competency, and patient safety culture, indirectly affected patient safety management activities. Conclusion: Self-efficacy, the perception of the importance of patient safety management, patient safety competency, and the organization's patient safety culture should be enhanced to improve nurses' patient safety management activities.

Purpose: This study was a meta-analysis of the effects of self-management on pain in patients with osteoarthritis. Methods: Randomized controlled trials were identified by searching PubMed, EMBASE, CINAHL, Ovid-MEDLINE and Korean database using key words, 'self-management', 'osteoarthritis' and 'pain'. Data were analyzed using the R version program. Results: Twenty nine studies met the inclusion criteria with a total of 5,998 participants. There were significant differences in overall effects of self-management (SMD -0.53, 95% CI -0.77~-0.29, p<.001). Conclusion: The results of the study show that self-management was effective in reducing pain in patients with osteoarthritis. As a result, it should be used as basic data when using self-management for patients with osteoarthritis.

Query language has been widely used as a convenient tool to obtain information from a database. However, users demand more intelligent query processing systems that can understand the intent of an imprecise query and provide additional useful information as well as exact answers. This paper introduces a meta-database and presents a query processing mechanism that supports a variety of intelligent queries in a consistent and integrated way. The meta-database extracts data abstraction knowledge from an underlying database on the basis of a multilevel knowledge representation framework KAH. In cooperation with the underlying database, the meta-database supports four types of intelligent queries that provide approximately or conceptually equal answers as well as exact ones.

본 논문은 레거시를 통합 검색하기 위한 방안으로 XMDR을 확장하는 방안을 제안한다. 이러한 확장은 메타데이터의 관리를 위한 메타 시멘틱 온톨로지, 위치 정보를 위한 메타 로케이션, 그리고 시멘틱 웹을 표현하기 위한 표준 언어인 토픽맵을 결합한다. 본 논문에서는 이것을 TMDR(Topic Map MetaData Registry)이라 한다. 토픽맵은 지식계층으로 인덱스와 같은 역할을 수행한다. 그러나 토픽맵은 데이터의 변화가 빈번한 경우에는 효율이 떨어질 수 있다. 이러한 문제를 해결하기 위해 본 시스템은 메타 데이터 사이의 관계, 실제 데이터 사이의 관계 그리고 메타데이터와 실제 데이터 사이의 관계를 토픽맵으로 표현한다. 표현된 토픽맵은 메타 데이터 간의 관계로 인해 실제 데이터간의 관계 변화를 줄이는 방안을 제시한다.

A well-designed computer network technology produces benefits on several fields within the organization, between the organizations(suborganizations) or among different organizations(suborganizations). Network technology streamlines business processes, decision process. Graphs are useful data structures capable of efficiently representing a variety of networks in the various fields. Metagraph is a like graph theoretic construct introduced recently by Basu and Blanning in which there is set to set mapping in place of node to node as in a conventional graph structure. Metagraph is thus a new type of data structure occupying its popularity among the computer scientists very fast. Every graph is special case of Metagraph. In this paper the authors introduce the notion of Meta-Networking as a new network technological representation, which is having all the capabilities of crisp network as well as few additional capabilities. It is expected that the notion of meta-networking will have huge applications in due course. This paper will play the role of introducing this new concept to the network technologists and scientists.

In keeping with the fourth industrial revolution, IoT-based environments are being implemented everywhere, and as a result, there is an increasing number of cases in which various types of sensed data are utilized efficiently. In particular, the number of multimedia application cases using smart devices is increasing, and there is an increasing number of cases in which large amounts of data are used as fast and convenient as small amounts of data. Given the increasing size of files used in smart devices, the study designed a modified Htree based on journaling meta data management in Ext4-based smart devices and analyzed performance through experiments of various methods. Performance evaluation analysis using IOZone and Hdread shows that the data size of 100Mbyte compared to the data input / output of existing htree is 10% or more, and that of the super large capacity file of 500Mbyte or more is 5% or more.
