In order to solve the problems of the digital library's Interoperability and integrated management, we analyzed core technologies for interoperability in digital library in terms of information creation, organization, service. And then we proposed information technology reference model that is composed of 7 scopes. The proposed scope included 1)Metadata Management, 2)Library Services, 3)Service Integration 4)Service Management, 5)Open Interface, 6)Network, 7)Architecture. Those results can be used as a framework for developing interoperable digital library system.

Information institutes in the world provide users with collaborative digital reference service for answering users' questions. Korea Institute of Science and Technology Information has conducted Question포인트+ that is CDRS using global mechanism. KISTI has developed two types of global collaboration mechanism on CDRS: one is using Global Network, the other one is direct cooperation between KISTI and a German organization ZLB. This study analyzes the current global collaboration mechanism of CDRS at KISTI and suggests the future model of global collaboration mechanism to satisfy the users' needs.

Video quality is degraded by codec and transmission error. By analyses video pattern through NR(no reference) method, we get to aware that telephony video has particular blocking and blurring pattern and NR is suitable for telephony video quality testing. So NR will make contribution to enhancing video quality and monitoring video quality in advance.

Clinically, three holstein dairy cattle showed the inappetence and decrease of milk production with severe lameness and pain. Grossly, strawberry-like proliferation of the skin between the heel bulbs were observed 4${\times}$5${\times}$1.5cm in size. Histopathologically, severe hyperplasia of epidermis, parakeratotic hyperkeratosis and multifocal ulceration of cornified cell layer, acanthosis, spongiosis of prickle cell layer and irregular arrangement of basal cell layer were seen. And focally observed the lesions of necrotic vasculitis, infiltration of inflammatory cells, congestion and hemorrhage. Spirochete bacteria were found in necrotic and outer proliferated epidermal cells by Levaditi's silver stain. Clinical and pathological findings were consistent with dermatitis verrucosa.

This study examines the access points for electronic reference service system displayed on the home pages of academic libraries. Library home pages of national/public and private universities were examined, and these were classified into three groups according to the methods of displaying access points on the homepages. The advantages and disadvantages of each group were discussed and some suggestions were made for the user-friendliness and accessibility for the electronic reference service.

The location information of wired 112, 119 emergency call is provided immediately by subscriber database of KT. But emergency call made by mobile phone should be ask location information to mobile network. This paper proposes the network protocol for mobile emergency service refer to TIA/EIA/J-STD-036-A with reviews about technical issues, legacy factors and related researches. The mobile emergency service is divided to mobile emergency rescue service and mobile emergency alert service. The network reference model for mobile emergency rescue service is released in domestic sector. In this paper, the interfaces between modules of the network reference model, and service scenarios, message flows are defined. Supplement to mobile emergency rescue service, the network reference model, interfaces and message flows for mobile emergency alert service are developed.

The Korean nationwide differential global positioning system (NDGPS) reference station transmits a global positioning system (GPS) enhancement signal using minimum shift keying modulation with a 200 bps data rate. The ocean-based DGPS covers the service area of 100 NM with 300 W output power; on the other hand, the land-based DGPS transmits the output power of 500 W, which covers the service area of 100 km. The DGPS reference stations with high output power can radiate spurious signals, which may act as interference sources affecting the other DGPS reference stations or the wireless ground stations that utilize the medium frequency band. In this paper, the radiation spectrums of the DGPS reference stations are measured and analyzed in the spurious domain. The DGPS radiation spectrums are evaluated from the perspective of the interference effect.

This study intended to examine and analyze current status of CD-ROM use in reference and information service in major university libraries. 66 university libraries with holdings of over 200,000 were selected throughout the country, and questionnaires were sent out by mail for data collection. Current status of CD-ROM use, some issues and problems on CD-ROM searching by reference librarians and users, and future trends of CD-ROM use were examined. Few suggestions were made for the effective CD-ROM use in reference and information service.

In this research, we attempt to discuss about the subject reference service from a marketing point of view, especially from a perspective of customer relationship management(CRM), and examine how this service actually functions to build the relationships with users of academic libraries, especially with faculty members. To carry out the research, a focus group interview was conducted with subject specialists, and also individual in-depth interviews with faculty members. In addition, we also discuss about characteristics of subject specialists which affect the relationship with the faculty members in a college environment. This study is meaningful as it discussed purposes of and characteristics in subject reference service from user' viewpoint and the perspective of CRM.

Most of the university libraries in Korea provide digital reference service(DRS), but the use of DRS is very low. The low usage of DRS seems to result from the lack of subject librarians, of staff, of public relations, and of managers' enthusiastic attitude and understanding of DRS. It is difficult to solve these problems because of the poor circumstances in universities. The collaborative digital reference service(CDRS) is a solution to these problems. Not only CDRS costs little but also can provide reference services in many different subject areas. Though subject specialist librarian, user-friendly system interface, system programs and administrative supports are necessary to implement CDRS, the education and training of the subject specialist librarians is the most important work to be done in the university library situation in Korea.
