This study aims to investigate the current state of digital reference services using electronic bulletin boards in Korean academic libraries and to suggest improvements. Through the examination of 205 academic library websites, 56 libraries were identified to use electronic bulletin for digital references. The digital reference service questions and responses from four libraries were further analyzed: the types of reference question, the structure and accuracy of answers, and digital reference completion time. The implications of this study for future research and practice lie in its provision of a systematic way to design practical guidelines for virtual reference services.

Demand for new information services is ever increasing as information technology advances in an unprecedented pace. Capabilities of information technology to overcome the time and space limitations enables efficient storage and processing of a large volume of data shared by many users in geographically dispersed areas. As the users ask for more useful information services, it is necessary to develop information services tp meet the needs of users. Enhancing information services is also necessary to cope actively with the pressures to open the information service is also necessary to cope actively with the pressures to open the information and telecommunications market as the level of Korean information services industry is still in its infancy. Value Added Network(VAN) services have a tremendous growth potential and its economic and social impact would be great as the information society matures. This study suggests a direction for the development of value added and new-media services based on the survey of individual and business users of information services.

In this Paper telemetering system for home automation is Proposed and implemented. Proposed and developed systems are composed with a home server and a few clients which send metering data of gas electric power water and home security to home server using power line communication. Management computer located in office of apartment complex collects all kinds of measured home data from each home server with multi drop communication by UDP Protocol A simple ASK method is used for power line communication Collected data from each home can be used for issuing the bill of each house and web service. The experiments were carried out under laboratory environment using various kinds of electric home appliances to ascertain the performance.

Public electronic certificates, as an important means for identification, have been used as the main economic transactions, including banking, e-government, e-commerce. identification. However, damage cases of certificates have been increased by Illegally issued and by hacking practices. Also the users have a difficult in ensuring that their certificates when and where to use. Therefore, the proposed system gives the organization code for the Institutions using OCSP services in advance, the organization code embedded in extensions of OCSP request message structure when institutions ask the validation of certificate to CA(Certificate Authority). Also, OCSP server can extract the organization code from OCSP request message, confirm the institution, and record it in certificate history management table of DB. In this paper, we presented a system that could determine the certificate history check using OCSP service, public electronic certificate validation service, and implemented to prevent and cope immediately with financial incidents.

Electronic channel of automobile insurance has emerged as an attractive way of lowering costs and saving time to do the transaction for customers. Electronic channel refers to using web sites to find useful information on insurance products, buy automobile insurance, and ask for services related to the insurance. This study suggests a modified model of the UTAUT and examines the factors influencing intention to use electronic channel in the transaction of automobile insurance. Based on 203 responses from potential automobile insurance buyers, the results showed that performance expectancy, effort expectancy, social influence, service expectancy, and security risk are significantly related to intention to use electronic channel. The results also showed that age as a moderator influences the effects of performance expectancy and effort expectancy on intention to use electronic channel. The study results would improve the understanding of the factors to which managers of insurance companies should pay attention in order to increase their sales through electronic channel.

서울시 120 다산콜센터는 서울시민의 민원문의 및 처리를 위해 도입된 전화 민원서비스이다. 공공 부분 정보제공 서비스 사업으로는 드물게 매우 활발하게 이용되고 그 역량을 인정받아 다수의 기관으로부터 벤치마킹(benchmarking)의 사례가 되어 왔다. 도서관계에서는 그동안 도서관 이용자의 정보 요구를 해결하기 위한 온라인 오프라인 참고정보서비스(Ask-a-librarian)를 시도하였으나 그 이용실적은 저조하였다. 이에 본 연구는 다산콜센터를 정보제공 서비스 측면에서 하나의 모범사례(Best Practice)로 판단하여 도서관계로 적용해 볼 수 있는 부분을 도출하여 제안해 보고자 한다.

Objectives: In this paper, we propose the ethical education direction by analyzing the personal information recognition and practice of music therapists. Methods: For the analyses, we selected 60 music therapists who answered a questionnaire from members of K Music Therapy Association, and analyzed task recognition and practice ask performance using IPA method. Results: In the IPA table, the areas of high recognition and practice (1) are the areas of personal information protection information management. In the IPA table, the areas of low awareness and high practice (2) are areas of privacy communication for those who have completed ethics education. In the IPA table, the areas of low awareness and low practice (3) are areas of privacy communication when ethics education is not completed. In the IPA table, areas of high awareness and low levels of practice (4) are areas of privacy protection. Conclusions: Continuing education should be provided to improve the curriculum on the protection of personal information for music therapists, thereby raising the awareness and practice of privacy.

In the recent industry, unmanned systems are expected to continue to spread throughout the economy. Especially in case of cosmetics, Users do not buy it right away. They look around, test it thoroughly, check the reviews, and decide on the purchase. Therefore, unmanned system using kiosk is more popular than face - to - face service of clerks. In this study, the persona analysis was completed based on the results obtained from the questionnaires and in - depth interviews. After sorting out the needs of the users, we applied them to the kiosk UI design of "Lalavela". The purpose of this study is to propose a kiosk UI design that helps many users who want to know information about the product though they are reluctant to ask directly to the clerk.

Loan consultants assist clients with loan application processing and loan decisions. Their duties may include contacting people to ask if they want a loan, meeting with loan applicants and explaining different loan options. We studied the efficiency of service quality of loan consultants contracted to a bank in Korea. They do not work as a team, but do work independently. Since he/she is not an employee of the bank, the consultant is paid solely in proportion to how much he/she sell loans. In this study, a consultant is considered as a decision making unit (DMU) in the DEA (Data Envelopment Analysis) model. We use a principal component analysis-data envelopment analysis (PCA-DEA) model integrated with Shannon's Entropy to evaluate quality efficiency of the consultants. We adopt a three-stage process to calculate the efficiency of service quality of the consultants. In the first stage, we use PCA to obtain 6 synthetic indicators, including 4 input indicators and 2 output indicators, from survey results in which questionnaire items are constructed on the basis of SERVQUAL model. In the second stage, 3 DEA models allowing negative values are used to calculate the relative efficiency of each DMU. In the third stage, the weight of each result is calculated on the basis of Shannon's Entropy theory, and then we generate a comprehensive efficiency score using it. An example illustrates the proposed process of evaluating the relative quality efficiency of the loan consultants and how to use the efficiency to improve the service quality of the consultants.
