An understanding the information seeking-behaviour of archival users is a basic for archival reference services. This study tries to understand who are users of internet board of archives, how and why they ask questions. And the study examines how archivists answer the users' questions. The data used in this study are 3,760 answers and questions in the internet board of National Archives and Record Service during $2000\sim2005$. According to this analysis. lots of users of the board make queries for archival management and asking various archives. And they are public officials, archivists, students, researches, and producers of media. The users mainly ask simple questions and it take average 5 days for users to get answers.

Standardization of technology for formatting multiple audio tracks and relevant information for interactive music service is in progress owing to the increasing need of consumers for participating in music production to their own taste. In this paper, we introduce the status of MPEG-A Interactive Music Application Format (IM AF) standardization and analyze techniques adopted in the current IM AF.

Depending on point of view, a service can be defined as interactions between customers and service providers or service delivery processes or customer's experiences. To develop and design a new service, the most of approaches presented in the previous researches represent a service mainly by the interactive activities or functions between customers and providers. The critical features of services which differentiate services from physical products are the inseparability that production and consumption occur at the same time and the heterogeneity that each customer ask their requirements to providers. To reflect the characteristics on the service model, we have to include contextual features in the service model. For the purpose, we define a service as the process of solving the customer's problems and a service is structured into three components: contacts, informations, and activities. We suggest the job mapping diagram to model a service process by the three components and then apply it to a hotel service process and compare the result with it of a blueprint.

In recent years, RFID is widely used in Industrial applications including factory, material flow, logistics and defense areas. In this paper, we developed a RFID baseband system with ASK modulation and convolutional channel code. A commercial ASK RF module is used and its frequency range in $350\sim351MHz$ and power is 10mW and the convolution code is constraint length k=3 and rate R=1/2. The performance is measured by frame error rate and the convolutional code is very useful in performance improvement and, also we implemented the binary search algorithm as anti-collision method and we show the wave shapes whit collision occurrence. This RFID system is designed by FPGA therefore it produces result of speed-up and improvement of reliability.

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.

이 연구는 노인의료복지시설 소속 요양보호사들을 대상으로 자기효능감과 직무만족에 대한 요양보호사들의 주관적 인식의 차이를 분석해 보고자 하였다. 분석결과 요양보호사들이 근무하는 노인의료복지시설 유형에 따른 인식의 차이는 없었지만 전체적으로 요양보호사들의 자기효능감과 직무만족의 충족이 노인의료서비스 제공에 있어서 중요하다는 것을 강조하였다. 따라서 노인의료복지시설 소속 요양보호사들이 노인들에게 의료서비스 등을 제공함에 있어서 직무만족과 동시에 지속적으로 높은 수준의 자기효능감을 유지할 수 있도록 하는 인적자원관리전략이 필요함을 시사하였다는데 그 의의가 있다.

Recently the study about a smart health care which is combined IT with BT to provide a variety of health care services are being actively investigated. In order to provide the best possible emergency medical services in a short period of time, it is necessary that the rapid emergency measures in the event of an emergency essential. In this paper, we propose an emergency medical service platform to take effective first aid to person who has a NFC tag or NFC-enabled mobile smart phones in an accident. Using NFC, it is possible to help without physical contact to the patient unconscious to emergency incidents such as falling down in everyday life. In this paper, we design and implement an mobile emergency medical system that can deliver first aid information ask for help in case of emergency.

Recently the interest in the information privacy has been growing. Digital data can be easily transferred via Internet. Service providers ask users for private data to give customized services. Users believe that their shared data are protected as they deliver their private data securely. However, their private data may be leaked if service providers do not delete or initialize them when they expire. The possibility of information leak may lower if the service providers deal with users' private data properly. In this paper, we study the self-destruction of private data for information privacy and propose the glass-box model.

This study was conducted with the aim of identifying the current state and improvements of the public library services for older adult in Korea. According to the online survey of public libraries in urban areas across the country, a total of 172 libraries responded. Research shows that public libraries generally recognize the importance of elderly users, but there are limitations in active efforts. The priority area for library collection and space/facilities was to be strengthened by the expansion of large type and voice books/periodical books, as well as the need to ask librarians for help to find books in high bookshelves. In the case of library services/programs, the areas that need to be strengthened first were analyzed as social participation programs and humanities programs. The librarians in charge of information services expressed their opinions that more specialized services and programs should be planned and subdivided for the elderly generation in order to provide older adults' services unique to other older adults' service institutions.

To attain competitiveness in the severe competition of retailing, retailing firm like Aekyung department store composites multiplex entertainment shopping mall with other firms as key tenants like LG supermarket, Books Libro, and CGV. But in multiplex entertainment shopping mall customers who have experienced a service failure in key tenant's shops usually ask a compensation of service failure to the lessor like department store. Even though customers of multiplex entertainment shopping mall know that key tenants use different service strategy, personnel management system and operation system and so on, they do not rare of it. Why they do that? How can we explain this situation? This study explains customer's complaining behaviors in multiplex entertainment shopping mall using attribution theory and justice theory. The study presents a comprehensive model about the effects of the perceived attribution and fairness on customer satisfaction and suggests practical implications for retailing firms composing multiplex entertainment shopping mall.
