분산 네트워크 환경을 기반으로 다양한 시스템과 장비가 서로 연결되어 사용되고 있는 현재의 IT 환경의 문제점을 해결하기 위해 DMTF는 선도적인 기업 및 교육 기관과 협력하여 이기종 시스템간 상호호환성을 제고하기 위한 시스템 자원 관리 표준 규격을 제정해 나가고 있으며, 그 중 하나가 WBEM 표준이다. 이 표준에서는 공통 정보 모델인 CIM을 비롯하여 데이터를 인코딩하고 전송하기 위한 XML과 HTTP를 표준으로 채택하고 있으며, CIM 데이터를 더욱 효과적으로 표현하고 전송하기 위해 필요한 XML문서의 형식과 태그 그리고 HTTP 헤더와 오류 코드 등을 추가로 정의하고 있으며, 이들 표준의 적용에 있어 필요한 몇몇 요구사항들도 정의하고 있다. 본 고에서는 표준 규격을 바탕으로 WBEM 표준에서 채택하고 있는 데이터의 전송방식에 대해 자세히 소개하고, 끝으로 현재 WBEM 표준이 갖고 있는 문제점과 주요 이슈를 함께 살펴보고자한다.

데이터마이닝 분야에서 시계얼 데이터(time-series data)내에서 숨어 있는 순차패턴의 발견은 상품(Items)이나 어떤 사건(Event)과 같이 데이터의 특징이 명확한 대상에 대한 연구는 많이 되어왔으나 수치 값을 가지는 시계열 데이터에서 이들 내부에 숨어 있는 패턴을 발견하는 것은 최근에 관심을 가지게 되었다. 우리는 시계열 데이터를 시간적 변화에 따라 값의 변화 경향(Trend)이 같은 데이터 그룹을 패턴 요소인 벡터 (Vestor)로 표현하여 이들을 이용해서 흥미로운 패턴들을 발견한다. 이와 같은 벡터적인 표현으로 우리는 벡터들 간의 포함관계를 적용해 모든 가능한 형태의 패턴 발견을 목적으로 한다. 또한 경향성을 가진 패턴 요소를 사건(Event)과 같이 취급함으로써 다양한 종류의 시계열 데이터가 동시에 발생될 때 이들 상호간에 연관된 시간적 패턴을 찾을 수 있다. 따라서 이 연구에서 제안하는 경향성을 기초로 한 순차패턴의 탐식은 기업내부의 판매실적의 변화 패턴이나, 고객의 구매 행동분석에 적용이 가능하리라 여겨진다

Real-time processing of sensor data network, is one of the important factors. Each node in the detected data are required to be transmitted within a certain time since the accurate processing is possible. Thus, the data nodes are successfully delivered within a specified time, it is very important to check whether the. Recently more and more accurate real-time embedded systems are reliable and haejyeoseo been able to provide sophisticated services. Because of the inherent complexity of embedded systems in the physical world and the difficulty of predicting the difficulty of a safe design constraints on the runtime violation of system as to cause unexpected causes. Each node data in time detected by the time required to be passed in the appropriate processing is possible because the data transfer time in this paper, the monitoring of the sensor network through a node are allowed to exist within the time range and transmits data to the server Analysis of the data transfer time for checking whether the system was implemented. Implementation of the data transmission time to the process for analyzing and presenting, according to the procedure suggested by the transit time required for analysis a time difference analysis method, a data collection method and a data transmission time and transmission time calculating method presented.

In the recent, due to explosion of Digital Universe, the performance of computer and storage system is reducing. Therefore, the upgrade and capacity expansion needs is growing. Countermeasure for this problem is required fundamental and long-term solutions rather than piecemeal expansion. In this paper, we establish a data management policy for an enterprise through the operational status of storage system and the analysis of data value of it, and implement ILM-based tiered storage system on the basis of these. The results of this study shows the overall throughput was improved about 21% compared to the existing system, it is very effective to maintain continuous quality and reduce operating costs in the long term aspect.

This study advances research on new venture by taking the organizational ecology perspective to explore the relationship between social legitimacy and new venture performance. We examine how entrepreneurs' organizing activity and social norm shape the social legitimacy. This paper also categorizes the social norms into three parts: social norm that is 1) supporting success achieved through one's own effort 2) encouraging start-up, and 3) promoting risk-taking. Using a dataset of PSED(Panel Study of Entrepreneurial Dynamics) from 2005 to 2011, we found that entrepreneurs' organizing activity has a positive effect on new venture performance. In addition, this study presents the moderating effects of 'liability of newness' that decreases the effect of organizing activity on new venture performance. Interestingly, with respect to the social norm, 'liability of newness' only moderates the relationship between start-up encouraging social norm and new venture performance.

Today, venture companies are increasingly important in that they play a key role in national economic growth. However, ICT venture companies are having great difficulties in securing a sustainable competitive advantage due to rapid environmental changes, and as one of the ways to solve this problem, they rely on the government's support policy. Accordingly, this study analyzed the effect of government support on management performance of ICT venture companies. For empirical analysis, the data from the 2016 ICT venture panel survey was collected, and 687 and 538 companies were selected to analyze the effect of funding and R&D support, respectively. Then, through propensity score matching, companies that received government support and companies with similar characteristics (control group) were compared and analyzed. As a result of the analysis, it was found that funding support had a significant effect on the growth potential of ICT venture companies, and R&D support had a significant effect on the stability of ICT venture companies. This means that there is a difference in management performance of ICT venture companies depending on the type of government support. Through this study, it was possible to confirm the effect of government's policies, and various support policies for specific purposes should be pursued to foster ICT venture companies. In addition, for the continued growth of ICT venture companies in the future, it will be necessary to consider package (technology, management, commercialization, etc.) support rather than individual funding support or R&D support.

This study has empirically analyzed how far corporate governance and CSR(Corporate Social Responsibility) fit are related based on prior research indicating that corporate governance is one of the primary factors. Previous research suggested that there may be different types of CSR fit, but there have been only limited number of empirical studies. This study filled this gap by categorizing CSR fit into three types (functional fit, target fit, and size fit) and investigating whether different types have different effects. We used data from the Corporate Social Responsibility White Paper for the 2009-2012 period, as well as the Korea Corporate Governance Service (KCGS) index. As a result, we found that there is a negative (-) relationship between corporate governance and CSR fit(${\beta}=-.023$, p<.05). This can be interpreted that companies with weak corporate governance are attempting to increase the trust level of stakeholders and to reduce the uncertainty of CSR through high-CSR-fitted programs. The test results showed that functional fit and target fit both had negative (-) relationships with corporate governance (${\beta}=-.021$, p<.05; ${\beta}=-.016$, p<.1), while size fit did not have a significant correlation with corporate governance (${\beta}=-.005$, p=.511). The results of this study supported the previous studies' suggestions that CSR fit has different effects on each type, indicating a need for further reflection on the relationship between corporate governance and CSR fit. Also, the results of this study showed that corporations should take a strategic approach to operating CSR fit.

This study endeavors to classify and categorize similar policy programs through network clustering analysis, using textual information from data-related policy programs in Korea. To achieve this, descriptions of data-related budgetary programs in South Korea in 2022 were collected, and keywords from the program contents were extracted. Subsequently, the similarity between each program was derived using TF-IDF, and policy program network was constructed accordingly. Following this, the structural characteristics of the network were analyzed, and similar policy programs were clustered and categorized through network clustering. Upon analyzing a total of 97 programs, 7 major clusters were identified, signifying that programs with analogous themes or objectives were categorized based on application area or services utilizing data. The findings of this research illuminate the current status of data-related policy programs in Korea, providing policy implications for a strategic approach to planning future national data strategies and programs, and contributing to the establishment of evidence-based policies.
