The purpose of this study is to develop the measuring instruments for evaluation criteria for Malcolm Baldrige National Quality Award(MBNQA), suitable for ICT Industries, and to analyze the cause-effect relationship between those criteria through aforementioned instruments. MBNQA is formed with seven categories: Leadership, Strategic planning, Focus on patients, other customers and markets, Measurement, analysis and knowledge management, Human resource focus, Process management and Results. As excluding the Human Resource Focus category, this study empirically examined the cause-effect relationship among six categories. In order to empirically examine the research model, this study calculated Cronbach's alpha and reliability index, thus examined the reliability and executed Exploratory Factor Analysis. Furthermore, Average Variance Extracted(AVE) is used to verify the discriminant validity. Lastly, the hypothesis testing was made complete through significance test on the paths between variables. The result of this study shows that both leadership and social responsibility have direct cause-effect relationship with Measurement, analysis and knowledge management, Human resource focus, Process management and also that this relationship has direct impact on Human resource focus, Measurement, analysis and knowledge management as well, consequently exerting influence on the result through Process management, Finance and Market data.

Reference services have taken a central place in library and information services. But current digital libraries focus more on access to digital information, and hardly lay emphasis on the service aspects. This paper looks at the current state of research in reference services in digital libraries. It first analyses some representative definitions of digital reference services. It then provides a brief overview of the various online reference and information services currently available on the Web. The paper also reviews the types of the digital reference service in major 'Aska' service sites. Finally, the paper proposes new digital reference service model that specifically bases on the sharing of the human and information.

Information modeling that is broadly applied in digital archiving process privides conceptual process that can be used to guide the creation of descriptions for the objects of preservation. However, it has faced with the limitations on substantially applying to the creation of preservation metadata records. This research proposes the concept of Resource Cluster in order to address these problems and efficiently describe the objects of preservation during digital archiving process. It also constructed Preservation Description Framework (PDF) based on RDF in order to substantially manifest preservation descriptions. This framework combines the structure of OAIS Reference Model and Functional Requirements for Bibliographic Records (FRBR) and can be an alternative approach to the creation of preservation metadata in more efficient and effective ways.

The purpose of this study is to propose the mandatory and extensible elements of Korea Education Metadata elements for digital course resources universities in Korea. For the study, literature research, case study and interview were performed. The mandatory elements of KEM consisted of sixty nine elements, and were proposed by two phases. Also, based on interview process twelve items were newly recommended to supplement KEM elements.

In order to advance forest resource management, it is necessary to solve problems such as the aging of forest-related industry workers and the field investigation system centered on manpower. Therefore, in this study, the trend of establishment and utilization of overseas forest geospatial information applied with the latest technology for scientific forest resource management was investigated to identify the domestic application plan. Overseas, photogrammetry and LiDAR technologies were being used to construct and utilize forest geospatial information. In the case of photogrammetry, it was used to measure the volume of vegetation, diameter, and tree height. And LiDAR technology has been applied to the measurement of diameter, and tree height. Through the analysis of overseas cases, it was identified how to construct forest geospatial information using photogrammetry and LiDAR, and it was found that LiDAR showed higher accuracy than photogrammetry. In the future, if the construction of forest geospatial information using various LiDAR sensors are performed and the accuracy and work efficiency are analyzed, it will be possible to present the possibility of using new technologies in the construction of forest geospatial information in Korea.

This paper proposes a new algorithm for comparing amplitude between multiple digital input signals and its digital logic architecture. After simultaneously comparing multiple inputs, the proposed algorithm can provide the information of the largest (or smallest) value among them by using a simple digital logic function. The drawback of the method is to increase hardware resource. To overcome this we propose a reuse method of the overlapped logic operation. The proposed method focuses on enhancing the operational clock frequency, in other words decreasing combinational delay time. After implementing the comparing method with HDL (hardware description language), we experiment on it with environment of Cyclone III EP3C40F324A7 FPGA of Altera Inc. In case of 4 input signals, it can increase the operational speed as mush as 1.66 times with 1.20 times the hardware resource. In case of 8, it can also have 2.29 times the clock frequency and 2.15 times the hardware resource.

The usage increase of digital contents required solution for protection technology and interoperability of system. MPEG proposed MPEG-21 Multimedia Frameworks. MPEG-21 IPMP is standard that provides the means to enable digital item and rights information to be persistently managed and protected across networks and devices. In this paper, MPEG-21 IPMP based system to protect digital contents designed by four structures of license server, production server, consumption server, tool sewer. License sewer create rights information document using the XML-based REL about multimedia contents of users. Production server makes a digital item by packaging multimedia resource and metadata, which is combined by REL information and IPMP information of multimedia resource. Consumption server takes care of the functions of players that use digital item, and tool server was implement to transmit for missing tool that night occur in all procedures.

아날로그 환경에서와 마찬가지로 디지털 환경에서도 디지털 컨텐츠 하나 하나에 고유 식별기호를 부여하여야 한다. 이러한 디지털 컨텐츠를 위한 식별기호로 IETF(Internet Engineering Task Force)에서는 URI(Uniform Resource Identifier)체계 하에 인터넷 자원에 대한 접근 메카니즘을 지정하는 URL (uniform resource locator)을 사용하고 있다. 그러나 도서관의 경우 각각 다른 OPAC(Online Public Access)시스템 환경 하에서 각각 다른 URL 식별 패턴을 사용하고 있기 때문에 동일한 자원을 검색하는데 있어서 문제가 되고 있는 것이 현실이다. 이러한 문제에 착안하여 본 연구는 디지털 콘텐츠에 대한 URL 식별구문패턴의 표준화 방안을 연구하고자 한다.
