도서관 서비스의 기본은 자료에 대한 이용자의 효율적인 접근을 지원하는데 있으며, 이를 위해서는 서지데이터(서지MARC)를 활용한 자료검색서비스의 고품질화가 전제되어야 한다. 그러나 국내에서는 도서관목록을 근간으로 한 자료검색서비스 관련 논의가 2010년대 초반에 머무르고 있어 자료검색서비스 현황을 파악하고 이용자 요구를 면밀히 살펴보는 작업이 필요하다. 이러한 맥락에서 이 연구는 도서관목록이 이용자 요구에 기반한 효율적인 자료탐색도구로 거듭나기 위한 방향을 제안하는데 목적이 있다. 이를 위해 첫째, 부산지역 49개 공공도서관 자료검색서비스를 '목록검색 방식'과 '정보제공 방식'에 따라 분석하였고, 둘째, 공공도서관 이용자 322명을 대상으로 설문조사를 실시하여 이용자 요구를 파악하였으며, 마지막으로 자료검색서비스의 우수 참조사례를 근거로 현황과 요구사이의 간극을 좁힐 수 있는 개선방향을 제안하였다.

The present research addresses the system design for building a geospatially-based web services application for mobile users. In recent years, geospatial information(GI) and Geographic Information Systems(GIS) are significant resources in decision-making analyses at various levels of society and activities. Recently, the integration of GIS and web services, called GIS web services, provides the wider implementation of GIS. At the present time, accessing, presenting, and manipulating updatedgeospatial information to locate geo-related facility services are real challenges related to application developers to implement for foot-travelers properly. The present paper investigates how the web services work in a GIS for discovering geo-related facility services such as a restaurant and post office in the user's vicinity. Thus, a prototype, with an architecture consisting of a windows application on the client side as well as facility services and geo-engineon the server side, were designed and implemented with the proposed GIS web services platform. On both the client and server sides, visual studio .Net technology was used. A geo-engine on the server side was also built with ESRI's MapObjects. Following successful implementation of the prototype presented in this study, the mobile user is able to invoke remote web services to assess the location of various facilities such as restaurants. Moreover, the present research demonstratesthat web services are not restricted only to web-based use, but can also be utilized by any web-connected application.

Recently, web-based service software has been used as to combine various information or to share information according to the needs of users and the convergence of specialized fields and individual dependent systems. According to the necessity of the user, the proper service environment and the selective service environment according to the purpose and the needs of the user have been studied in a variety of specialized and combined professional research fields and industries. Software based on cloud systems and web services is being used as a tool for appropriate group and user groups and roles. A service system combined dynamically needs a module to manage a user through internal logic and grant a service access authentication. Therefore, it has been considered various approaches that a user who accesses the system is given a service access authority for a certain period of time. Also, when the deadline is over, the authority that you are given to access system will go through the process of expire the right. In this paper, we define the roles of users who access web services, manage user rights according to each role, and provide appropriate service resources to users according to their rights and session information. We analyzed the procedure of constructing the algorithm for the service according to the procedure of each user accessing the web service, granting the service resource and constructing a new role.

This paper introduces an approach for providing Location Based Services (LBS) using Spatial Location (SLO) information within the Session Initiation Protocol (SIP). The aim of the paper is to set up the framework for providing LBS services in devices connected to wire and wireless IP networks. This method uses SIP as transport and the SLO as data formal inserted in the SIP pay-load. It analyses the relationship among the network elements involved in the architecture, and its functionality fur providing access to network services regardless of the user location. In conclusion, this proposal enables SIP to support location-related services such as messaging, location-based commerce, and any location-based computing. Furthermore, it describes the advantage of adding the user location information network resources optimization in mobile environments and future networks.

Location-based services (LBSs) have become popular in recent years due to the ever-increasing usage of smart mobile devices and mobile applications through networks. Although LBS application provides great benefits to mobile users, it also raises a sever privacy concern of users due to the untrusted service providers. In the lack of privacy enhancing mechanisms, most applications of the LBS may discourage the user's acceptance of location services in general, and endanger the user's privacy in particular. Therefore, it is a great interest to discuss on the recent privacy-preserving mechanisms in LBSs. Many existing location-privacy protection-mechanisms (LPPMs) make great efforts to increase the attacker's uncertainty on the user's actual whereabouts by generating a multiple of fake-locations together with user's actual positions. In this survey, we present a study and analysis of existing LPPMs and the state-of-art privacy measures in service quality aware LBS applications. We first study the general architecture of privacy qualification system for LBSs by surveying the existing framework and outlining its main feature components. We then give an overview of the basic privacy requirements to be considered in the design and evaluation of LPPMs. Furthermore, we discuss the classification and countermeasure solutions of existing LPPMs for mitigating the current LBS privacy protection challenges. These classifications include anonymization, obfuscation, and an encryption-based technique, as well as the combination of them is called a hybrid mechanism. Finally, we discuss several open issues and research challenges based on the latest progresses for on-going LBS and location privacy research.

China has the largest number of the user of web 2.0 such as messengers and blogs, as of 2008 year. Chinese Internet digital market will grow from $85 billion in 2007 to $264 billion in 2015. The importance of Chinese Internet business is increasing, because of its size and growth potential. This research is focused on following two questions. First, what are the major characteristics of social networking services in China? In order to find out the answer about this question, the case study on Tencent QQ and Sina Poco, the most representative social networking services company in China, was done. And the reason of the use of social networking services, their contents, and the attitude toward the paid service were identified. Second, what are the major factors influencing the use of social networking services in China. User participation, network effect, usefulness, and system quality were inferred as the factors influencing the use. These factors were based on motivation theory, technology acceptance model, and the related research papers. This research model was proved by data analysis using Partial Least Square. As results, the use of social networking services was influenced by usefulness, network effect, user participation, and system quality. But social influence was not significant of the use of social networking services.

무선 통신 기술 및 GPS(Global Positioning System)등의 발달로 인하여 위치 기반 서비스 (Location-Based Services: LBS)가 크게 발전하는 추세이다. 그러나 위치 기반 서비스를 이용하기 위해 질의 요청자는 자신의 정확한 위치 정보를 위치 기반 서비스 제공자에게 전송해야 한다. 따라서 위치 기반 서비스를 제공하면서 질의 요청자의 위치 정보를 보호하는 것이 중요한 과제이다. 이 문제를 해결하기 위해, 기존 기법은 실제 사용자의 위치를 숨기며 네트워크 사용을 줄일 수 있는 2PASS 기법을 사용하였다. 그러나 이 기법은 실제 사용자 분포를 고려하지 않기 때문에 실제 사용자 위치 보호를 완전히 보장하지 않는다. 따라서 본 논문에서는 K-anonymity를 보장하는 가중치 근접성 그래프 기반 최근접 질의처리 알고리즘을 제안한다. 제안하는 알고리즘은 질의 영역 내 K-anonymity를 보장함으로써 사용자의 위치 정보를 보호할 뿐만 아니라 불필요한 질의 결과 탐색을 줄여 네트워크 효율을 증가시킨다. 마지막으로, 성능평가를 통해 제안하는 기법이 기존 연구에 비해 질의 처리 시간 및 네트워크 효율 측면에서 우수함을 보인다.

In this paper, we discuss the design and implementation of a recommendation platform actually built in the field. We survey deep learning-based recommendation models that are effective in reflecting individual user characteristics. The recently proposed RNN-based sequential recommendation models reflect individual user characteristics well. The recommendation platform we proposed has an architecture that can collect, store, and process big data from a company's commercial services. Our recommendation platform provides service providers with intuitive tools to evaluate and apply timely optimized recommendation models. In the model evaluation we performed, RNN-based sequential recommendation models showed high scores.
