In this study, users' perceptions and concerns about digital information resources were investigated, focusing on impediments to the use of digital resources, to devise measures for improvement by identifying factors that hinder the use of digital information resources. To achieve the purpose of the study, the research identifies the inconvenien ce factors and establishes the user inconvenience list based on prior research and the current status survey. Based on the derived list, a survey was conducted on users of public libraries. Through this study, it was found that the use of digital information resources can be enhanced by improving the internal library system. Specifically, it refers to improving search performance and accessibility of digital data, providing one-stop services for digital information resources through the operation of an integrated data management system, conducting customized user education, and establishing a digital information resource preservation system, e.g. web archiving. Also, improving the external environment and system, such as contracting with more libraries for digitized data use agreements, strengthening support, unifying the names and classifications of digital information resources, and simplifying the procedure for using digital information resources, is of great importance.

Although merger and acquisition (M&A) has been considered as an important means to improve firm performance, most prior empirical research have failed to prove the relationship between M&A and firm performance. In order to fill this gap, this study attempts to identify the effect of M&A on firm performance based on knowledge resources relatedness and complementarity theory. For this purpose, this study examines complementarity patterns of knowledge resources and their impacts on acquirer's performance using M&A announcements of electronic commerce industry from 2001 to 2007. The results of this study indicate complementarity among knowledge resources are positively related with acquirer's market value. This study contributes to expand knowledge management research by identifying the relationship among knowledge resources and their impacts on firm performance.

최근 인터넷의 급속한 보급과 네트워크 자원을 비롯한 전자자료의 급증, 메타데이터의 출현 등으로 목록분야에 있어 환경이 크게 급변하고 있다. IFLA를 비롯한 관련 기관들이 이와 같은 변화에 대응하여 많은 연구와 함께 규칙들을 정비하고 있다. 본 연구에서는 디지털 전자자료의 목록과 관련하여 시대별로 주요한 흐름을 분석한 후, 전자자료의 목록과 직접적인 관련이 있는 ISBD(ER), AACR2R 2002 개정판, MARC 21, 더블린 코어, 한국목록규칙 제4판을 중심으로 보다 자세하게 살펴보았다. 그리고 오늘날 인터넷 자료를 조직하기 위해 시도되고 있는 대표적인 방법으로 인터넷상의 웹 페이지를 자동으로 색인하는 방법, 웹 자료를 기술하기 위해 고안된 더블린 코어 등과 같은 메타데이터를 이용하는 방법, 도서관에서 전통적으로 시행하고 있는 MARC 형식으로 목록하는 방법에 대해 비교 분석하였다.

The requirements for powerful computing capability, high capacity, low latency and low energy consumption of emerging services, pose severe challenges to the fifth-generation (5G) network. As a promising paradigm, mobile edge networks can provide services in proximity to users by deploying computing components and cache at the edge, which can effectively decrease service delay. However, the coexistence of heterogeneous services and the sharing of limited resources lead to the competition between various services for multiple resources. This paper considers two typical heterogeneous services: computing services and content delivery services, in order to properly configure resources, it is crucial to develop an effective offloading and caching strategies. Considering the high energy consumption of 5G base stations, this paper considers the hybrid energy supply model of traditional power grid and green energy. Therefore, it is necessary to design a reasonable association mechanism which can allocate more service load to base stations rich in green energy to improve the utilization of green energy. This paper formed the joint optimization problem of computing offloading, caching and resource allocation for heterogeneous services with the objective of minimizing the on-grid power consumption under the constraints of limited resources and QoS guarantee. Since the joint optimization problem is a mixed integer nonlinear programming problem that is impossible to solve, this paper uses deep reinforcement learning method to learn the optimal strategy through a lot of training. Extensive simulation experiments show that compared with other schemes, the proposed scheme can allocate resources to heterogeneous service according to the green energy distribution which can effectively reduce the traditional energy consumption.

Electronic Commerce with its advantages offered from the Internet to both the distributor and the customer, is growing faster than ever these days, and found its place to be the new designed Commerce Paradigm, raised as the means taking the lead of the national economy land society. The result proves that the diverse knowledge, occurring through the process of the establishment, is spread not only in the brain, but also in the diverse kinds of resources. With this research, we could find the waste of the resources and the controversial points occurred i when the developer do not use the methodology or the existing one. With the consideration and analysis on the Electronic Commerce and Workflow, We established the structure of the Electronic Commerce Workflow, developed the WfDM (Workflow Development Methodology) to build the model.

전파법은 2000년 전면 개정 이후 12차례의 개정을 통해 전파자원의 확보, 전파자원의 분배 및 할당, 전파자원의 이용, 전파자원의 보호, 전파의 진흥을 중심으로 규정하고 있는 현재의 모습을 갖추게 되었으며, 이로써 전파자원의 단순한 관리법적 성격을 벗어나, 전파자원의 확보 및 전파의 진흥법적 성격을 포함하는 것으로 평가될 수 있다. 통신 분야의 법제도도 함께 정비되어 가고 있으며, 전파법도 2차례의 개정을 통해 그간의 미비점들을 보완하고 있다. 국내 전파법은 전파이용 환경 변화에 따라 자원의 효율적 배분 및 이용을 촉진하기 위한 법체계를 형성한 것으로 평가되며, 기존의 단순한 관리법적 성격에서 전파진흥 및 경쟁 관련 법적 성격을 갖게 된 것으로 평가할 수 있으며, 전파이용 유형별 세부 규정에 대한 조정은 필요한 것으로 판단된다.

The study aims to investigate the determinant factors in the organisation of a firm's innovative activities, and the impact of innovation capability on firm's performance of electronic firms in Ho Chi Minh city, Vietnam. How is the performance of electronic companies after delivering an innovation project? How will innovation capability affect firm's performance in electronic companies? This study aims to seek the answer of these questions. We employ a Structural Equation Model and the PLS technique in order to validate the theoretical model proposed in this study. With observation of 374 valid firms, based on Cronbach's Alpha analysis, EFA analysis, CFA analysis and SEM analysis, this study discovers 5 groups of factors including: (i) Institution factors; (ii) Attitude of leadership factors; (iii) Marketing factors; (iv) Technological resources factors; (v) Combination factors, which have direct impact on innovation capability of firms. There are 4 groups of factors that have positive impacts on financial performance of electronic firms, with descending order of importance as follows: (1) Attitude of leadership factors; (2) Quality of human resources factors; (3) Innovation capability; (4) Marketing activities factors. Research results are important implications for Government administrative agencies for business to consult and introduce effective support policies.

Test scheduling of SoC becomes more important because it is one of the prime methods to minimize the testing time under limited power consumption of SoCs. In this paper, a heuristic algorithm, in which test resources are selected for groups and arranged based on the size of product of power dissipation and test time together with total power consumption in core-based SoCs is proposed. We select test resource groups which has maximum power consumption but does not exceed the constrained power consumption and make the testing time slot of resources in the test resource group to be aligned at the initial position to minimize the idle test time of test resources.
