The purpose of this study is to develop an effective information service process based on user's characteristics and needs in academic libraries. The process was informed by analysis of the entire information service cycle using real users as an exploratory study. The interview process between the user and information provider, and the information provider's perspectives regarding information services demonstrated that the user's information and subject analysis, effective interview methods, communication skills, information provider's recognition of information services, and core ability are important elements for effective information services.

Recently Android apps utilizing location based services are widely used. Understanding the operation of the GPS location provider, among various location providers supported in the Android platform, is an essential task for developers using the Android. This paper, based on the analysis of source codes of the GPS subsystem in the Android platform, shows clearly and orderly the operation of the GPS location provider, in key threads' perspectives as well as in a stepwise fashion from the initialization up to the final location report steps.

Content-Centric Networking(CCN) is a new networking paradigm to search for the routing information needed to find a data from the content name, unlike conventional IP networks. In CCN, the mobility management, one of the CCN challenges, is consists of consumer mobility and content provider mobility. Among both, in the case of the content provider mobility, it requires too much overhead and time to update routing information on the corresponding routers. In this paper, we propose Popularity-based Pushing CCN(PoPCoN) which considers the content popularity to support effective mobility of content provider in CCN. Our proposed algorithm shortens content download time for the consumer and reduces the network overhead during mobility as compared to the existing approaches.

According to many smart devices are development, SNS(Social Network Service) users are getting higher that is possible for real-time communicating, information sharing without limitations in distance and space. Nowadays, SNS users that based on communication and relationships, are getting uses SNS for information sharing. In this paper, we used the SNS posts for users to extract the category and information provider, how to following of recommend method. Particularly, this paper focuses on classifying the words in the text of the posts and measures the frequency using Inception-v3 model, which is one of the machine learning technique -CNN(Convolutional Neural Network) we classified image word. By classifying the category of a word in a text and image, that based on DMOZ to build the information provider DB. Comparing user categories classified in categories and posts from information provider DB. If the category is matched by measuring the degree of similarity to the information providers is classified in the category, we suggest that how to recommend method of the most similar information providers account.

The primary purpose of this study is to investigate ASP (Application Service Provider) vendor attributes that affect ASP client satisfaction. From the relevant literature, ASP vendor attributes that might affect the ASP client satisfaction were derived from which the survey questions were formulated. The survey was conducted among the companies that have adopted ASP. Through the factor analysis of the survey results, the following vendor attributes - vendor's IT infra structure, service reliability, service flexibility, vendor stability, IS maturity, information sharing - were derived ; and the relationships between those attributes and ASP client satisfaction were explored. The result of this study revealed that IT infra, service flexibility, vendor stability are related to ASP client satisfaction. The customer satisfaction factors in the traditional outsourcing -- reliability, IS maturity, information sharing were proved to be not applied in ASP environment. This study provides ASP vendors with guidelines on how to improve their ASP strategies to satisfy clients. The results of this study can also be used by client companies as a decision basis for ASP vendor selection.

인터넷 정보서비스의 다양화와 전자상거래의 활성화로 다양한 CP(Contents Provider)들이 등장하고 인터넷 비즈니스 모델에 유료 컨텐츠 제공을 통한 컨텐츠 비즈니스가 새로운 수익 모델로 등장하게 되었다. 이러한 추세에 발을 맞추어 컨텐츠에 대한 정보이용료 처리를 수행하는 시스템의 필요성이 증대되고 있다. 기존의 PC 통신의 IP(Information Provider)들을 텍스트 위주의 분당 사용료에 따른 종량제 서비스를 제공하여 수익을 올릴 수 있었지만 CP들은 그렇지 못했다[9]. PC 통신을 통해 정보를 제공하는 IP와 인터넷을 통해 정보를 제공하는 CP의 특징으로 기존 CP 제공 유형은 인터넷상의 정보 사용료 처리부분에 대한 수익금 정산처리의 어려움으로 IP방법을 모방하고 있다. 따라서 본 논문은 CP 특징을 이용하여 독자적인 홈페이지 운영으로 유료 정보 이용에 대한 이용료 부과 시스템 모델을 제안한다.

A service level agreement (SLA) is a formal contract between a service provider and a subscriber that contains detailed technical specifications called service level specifications (SLSs). In this paper, we propose SLA data analysis system which provides an effective decision-making information to network service provider. The SLA data analysis system executes trend analysis and statistics analysis using SLA violation and refund information. The analysis results are presented in many ways such as tables, graphs.

Recently , as GIS technology is rapidly improved and stabilized, there are some needs to reuse pre-developed and powerful GIS technology. GIS standardization based on components and open interfaces becomes a way to solve those reusability of previous GIS technology. This GIS standardization currently focuses on building the GIS Data Infrastructure that is being deployed globally. Especially, OpenGIS consortium which is mainly made up of international GIS leading vendors is announcing some GIS abstract specifications and implementation specifications. This study focuses on how could we design and implement the OLE/COM-based data provider component based on various DBMS or file systems, how could these data provider components be used for enterprise UIS(Urban Information Systems) and how could various formatted GIS data be shared in one system. Also some problems practically caused by an implementation process of data provider component are listed up and some solutions are given. Furthermore, design and analysis of UML(Unified Modeling Language) was reformed through the data provider component development task and this UML methodology is able to indicate a standardized model for newly developed data provider component.

It was difficult for user to identify e-books due to some problems such as duplicable bibliographic records and inconsistent descriptive cataloging when cataloging the bibliographic records of the e-book packages in OPAC. Therefore, the purpose of this study was to find the applicable methods of the provider neutral e-book(e-monograph) MARC record guideline for the standardization of the bibliographic records of the provider supplied e-book package. Through the literature reviews and homepage analysis of 15 university libraries in domestic, the theoretical background on cataloging e-book, the descriptive cataloging of e-book, the provider-neutral e-monograph MARC record guideline as new standard for e-book, and the libraries practices of cataloging bibliographic records of the e-book package were inquired. Based on these analysis, it was to suggest applicable methods of provider neutral e-book(e-monograph) MARC record guideline for the standardization of the bibliographic records of domestic e-book packages in aspect of cataloging rule, KORMARC, and neutral bibliographic records. This study will contribute to build FRBRization of the e-books in OPAC as finding the guideline for the standardization of the bibliographic records of the e-book packages for both providers and libraries.
