Marketing techniques developed for private organizations are being widely used in libraries. The primary focus in marketing has shifted to maximizing user perceived value from the perspective of library users. This paper examines library as an industry as a way to establish the basis for library's overall value, applies the R-I-R model and its taxonomy of value in using library and information services, and proposes market orientation approach to systematically plan and coordinate academic library marketing activities.

유비쿼터스 컴퓨팅이라는 개념이 정보통신 분야의 패러다임으로 자리잡은 지 오래임에도 불구하고 실생활에서 이용 가능한 유비쿼터스 컴퓨팅 관련 서비스는 극히 적다 U-Messaging 서비스는 카메라가 내장된 모바일 단말기와 무선 인터넷을 활용하여, 캠퍼스 환경이라는 물리적 공간과 센서를 활용함으로써 유비쿼터스 컴퓨팅 개념을 잘 보여주고 있다. U-Messaging 서비스는 이미지 태그가 부착된 명패와 단말기를 이용하여 방문자의 음성과 문자 메시지를 전달하고 사용자는 나중에 방문기록과 메시지를 조회하도록 해주는 서비스이다. 학생과 일반인을 대상으로 한 사용성 평가결과 서비스에 대한 인지성, 편리성, 유용성 측면에서 만족할 안한 결과가 도출되었다.

The purpose of this study is to provide implications for Korea's addiction measures by comparing the service delivery system for drug addiction in Korea and Japan. The method of research in this study is literature research. The collected data were analyzed using the Inter-Country Difference Act. According to the study, South Korea and Japan were supporting addicts and their families with a seemingly similar system for dealing with drug addiction. But the difference was also found. The difference between Korea and Japan on coping with drug addiction is, first, that Korea does not have an organization that only supports drug addiction. Second, continuous aid was insufficient even though it was an easy addiction to recur. As a suggestion to solve these problems, first, countermeasures for drug addiction alone are needed. Second, close and complementary links are needed within an integrated service delivery system. Third, persistence and appropriateness for treatment and rehabilitation are needed. Fourth, it suggested the need for preventive education contents.

There is a growing trend in developing system for distributed mobile system that supports services - job flow management, video conference, replicated data management and resource allocation. Supporting these services, applications have to use causally ordered message delivery. Previous proposals that provide causally ordered message delivery have problems such as communication overhead, message delaying, scalability, computing overload of mobile host. In this paper, we proposed efficient protocol for causally ordered message delivery using the methods that MSS maintains dependency information matrix between MSS and MH, Piggybacking dependency information about each immediate predecessor message. Proposed algorithm, when compared with previous proposals, provides a low message overhead, and low probability of unnecessary inhibition in delivering messages. Also, it consider resource restriction of MH and low bandwidth of wireless communication by computing most of algorithm at MSS, and reduce processing delay by executing causally ordered message delivery a unit of MH.

Physical One-way Transfer, one of network Separating Network Technologies, shut off intrusion possibilities by removing data transfer line from external network to internal network. Physical One-way Transfer technology can not support legacy services based duplex transmission. Legacy services operating need agent for extra service with the support. But, Agent development have problems with adding cost and open internal protocols. In this papers, We analyzed legacy services between Control network and OA network in working SCADA systems, and based on the results obtained from the analysis, categorized the legacy services into three forms. We propose an agent generation method of the three service categories for Physical One-Way Transfer System. In addition, we design an automatic generation tool using the proposed method.

To construct seamless collaborative environments, what all participants intent should be delivered, and visual elements such gesture, facial expression, and ambiance should be shared with all participants. In this paper, we propose high-quality video service to support DV(digital video) and HDV(high-definition DV) based on Access Grid(AG) which is a prevalent collaborative system. The proposed service is designed for employing versatile media tools and codecs with SDP(session description protocol) and SAP(session announcement protocol). We also design network-adaptive video transmission module to mitigate the impact of network fluctuation. This periodically monitors multicast performance and controls frame rate on sender side considering network condition. The experimental results over the test bed show that proposed service enhances quality of AG video service and provides seamless high-quality video transport by mitigating the impact of network fluctuation.

Although the data service of the digital broadcasting has been regarded as the representative service of the broadcasting and communication convergence, it, however, has failed to gain the popularity with the viewers due to the viewer's viewing modality of focusing only on the TV programs. Based on the experts' opinions that the data service should step up so that using a data service while watching a TV program creates a synergy effect, the paper proposes a method for allowing a data service to utilize the information of a TV program. The method has a tool for describing the information of a TV program's content, which changes as time goes on and provides a mechanism for transmitting the information in the way compatible to the digital broadcasting standard. As an application of the method, with a domestic data service developing company, we have developed a ticker data service that shows the information (e.g., actors, places, sponsors, etc.) of a drama.

At the most recent, IPTV service is increasing, which isa communicative broadcasting fusion service that provides various multimedia contents interactively followed by user's request through super high-speed internet. For IPTV user service with high mobility, IPTV user's enrollment is essential. However, IPTV service provided to mobile users can't provide the certification of mobile user securely. This paper proposes light user certification protocol which can certificate mobile users by attaching RFID to IPTV STB for secure awareness of mobile users who get IPTV service. The proposed protocol prevent reply attack and man-in-the-middle attack from happening oftenin a wireless section by transmitting the result value hashed by hash function with both its' ID and random number received from tag after tag transmits random number which generated randomly in the process of certification of mobile user to IPTV STB.
