Mobile service is highly becoming in the limelight on information society by offering infringement problem about individual privacy or information by political and scientific interest This study is focusing on primary LBS application Mobile service that emphasize position confirmation, especially, looking for friends. The aim at this study grasps user productivity factor of LBS application Mobile service, and analyses whether some have relations with value and action determination of LBS application Mobile service. According to result, Mobile service applying position service is supported with usefulness and system quality, adaptedness. On the other hand, Usability and social effect, privacy weren't embossed by leading person. Mobile service applying position service is changed with a person who have experience looking for friend. This study has systematically analysed about LBS application service by leading person

오늘날 다양한 VR(Virtual Reality) 기술의 발전으로 체감형, 몰입형 컨텐츠 시장이 급속도로 확대되고 있다. VR 기반 컨텐츠는 게임과 애니메이션, 영화와 같이 소비자에게 엔터테인먼트를 제공하는 목적으로 주로 활용되고 있다. 그러나 VR기술은 엔터테인먼트 뿐만 아니라 사용자에게 더욱 다양한 경험을 제공할 수 있다. 따라서 본 논문에서는 정보전달 위한 VR 게임을 설계 및 구현하고자 한다. 제안한 방법을 통해 미술관과 사적 건물 등과 같이 사용자에게 엔터테인먼트와 더불어 정보전달을 목적으로 하는 컨텐츠에 적용하여 활용할 수 있을 것이다.

In this study, two standard specifications such as GML (Geography Markup Language) from OGC (Open Geo-spatial Consortium, Inc.) and X3D (extensible 3D) from Web3D consortium were dealt with for a web-based 3D urban application without using commercialized tools. In the first step of this study, DEM (Digital Elevation Model) and 3D GIS data sets were converted to GML structure with attribute schema. Then, these GML elements were projected onto a common coordinate system, and they were converted to the X3D format for visualization on web browser. In this work, a 3D urban data model, as a simple framework model, is extended to a framework model having further detailed information, depending upon application levels. Conclusively, this study is to demonstrate for practical uses of GML and X3D in 3D urban application and this approach can be applied to other application domains regarding system integrators and data sharing communities on distributed environments.

현 식품 공급망은 중앙 집중화되어 있고, 투명하지 않으며 복잡한 시스템으로 인해 많은 문제점이 존재한다. 판매자는 싼값에 팔고 소비자는 비싼 값에 구매하는 문제가 지속적으로 대두되고 있으며 유통 과정에서 생기는 문제에 대한 책임 추적이 어렵다. 본 논문에서는 각 유통 단계에서 생성되는 IoT 센서 데이터를 블록체인 기술에 적용하며 이를 활용하는 방안에 대해 제안한다. 제안 모델을 통해 유동 과정과 데이터에 대한 신뢰성을 확보하고 제품의 원산지, 배송 과정, 보관 상태를 비롯한 유통 정보들을 추적할 수 있다.

Recently, in order to promote their marketing strategy, the entrepeneurs attach importance to many shopping Application services and execute it. The representative elements of shopping Application are interactivity, information offering, convenience of use. This study verified the effects of interactivity, information supplying, and usage convenience, the application characteristics, on the application preferences and repurchase intentions, and the moderating effects of price sensitivity and usage frequency. The result states that the shopping application characteristics affect the shopping application preference, In terms of price sensitivity, the group with higher price sensitivity showed more significant result on the interactivity and usage convenience, and when the information supplying affects on the application preference, the group with higher price sensitivity showed more significant result than the group with lower price sensitivity.

Customer Relationship Management(CRM) paradigm has emerged that suggests organizations will be more successfully if they concentrate on obtaining and maintaining a share of each customer rather than a share of the entire market, with information technology(IT) being the enabling factor. This paper presents five key elements that provide the necessary steps that allow and organization to position its people, business process, and information system to establish and take advantage of this paradigm. The key elements are : (1) IT investment, (2) Website application, (3) IT System application, (4) Communication strategies, (5) CRM Performance. The results show that IT investment, IT system application, and Website application play a vital role in enhancing an Organizational Communication. Also, the results show that IT investment, IT system application, Website application, and Organizational Communication play a vital role in enhancing an organization's performance of customer relationship management. Further, this paper discusses the importance of integrating these four elements for achieving effective customer interaction. The author provides academical and managerial implication for business strategies.

Computer는 발명되서부터 매년 응용분야가 넓어지고 있다. 현재에는 情 報處理라는 말그대로 어떠한 형태이든가의 복잡하고 다량의 情報가 存在하는 곳 에는 computer를 導入할려고 하든가, 또는 導入이 끝난 곳에서는 보다 큰 大規模 의 system으로 擴張하려고 하는 생각들을 보통 가지고 있다. 이러한 요구에 응하 여 왔던 것이 hardware, oprating system, 그리고 application software이다. 그중 hardware나 operating system은 多小 變化하여 왔지만은, 方式的으로는 application의 특성에 의한 요구에는 별로 틀린것이 없이 대개 같은 종류의 것이 쓰여왔다고 할 수 있다. 따라서 무수히 變하는 application의 複雜한 論理를 實現 하는 것은, 그 책임이 application software 개발자에 걸려있다. 그러므로 이러한 것들은 개발자(designer, programmer) 들의 개인의 기술과 努力에 달렸다고 말할 수 있다.

최근, 인터넷 사용자가 급증하면서 빠른 서비스에 대한 문제가 큰 관심이 되고있다. 특히 데이터베이스 시스템에서 저장 삭세 수정 등은 사용자에게 긴 대기시간을 요구할 수도 있기 때문에 사용자의 불평을 야기할 수 있다. 이 논문에서는 3-티어 방식에서 요즘 많이 사용되는 application server의 cache에 대해서 말하고자 한다. 기존 application server는 데이터를 application server cache에 저장하여 같은 데이터를 서비스할 경우 server의 cache를 사용하지만 이 논문에서 제안하는 것은 접속된 client를 관리하여 각각의 client에 cache를 만들고 application server나 또는 데이터베이스 server가 서비스를 하지 못할 경우는 가장 최근의 데이터를 가지고 있는 client를 찾아 client cache에 있는 데이터를 서비스 하자는 것이다.
