The quick report and propagate information are increasingly important because nowadays it is hard to predict the damages of flooding by unexpected heavy rain. In addition, there are not many ways to receive disaster information in real time. Accordingly, we designed the system which can earn information from a lot of messages on twitter. Above all, our system can extract and deploy disaster information by comparison with erstwhile social network service mash-up system as only broadcast media. Significant objective of this paper is to design the fastest extract disaster information system of mass media.

As digital environment rapidly changes, various identification infrastructures have been introduced. It inevitably caused the Interoperability issue between the identifiers. Especially, Interoperability issue between the same kinds of identifiers raised the problems such as decreasing usefulness and cost overhead for making bridge system. In this paper, we resolve this issue by suggesting ID mashup service based on XRI. Although both UCI and ICN are the dominant identification infrastructures in the soundsource domain, the modification of identifiers or the requirement of complex system are essential for Interoperability. The ID mashup service suggested in the paper is able to provide interoperable functions to outer world without modifying the structures and resolution service of both identification infrastructures.

As web 2.0 becomes one of the important architecture styles, more web applications adopt single page structure instead of multiple web pages and navigations between pages. A single page web application client, called a mashup client in this paper, interfaces more than one services and allows users to navigate in the page. A mashup client page includes complicated functions and has to handle various styles of services and user requirements, and therefore is usually developed manually. In this paper, we propose a model driven code generation approach for in-page navigations. We propose a page model and view navigation design approach, applying REST service architecture patterns. Then, we consider type conditions for each view to have service calls or navigation controls. Also, we developed an XForms page code generation system to demonstrate the efficiency of the proposed method. The developed system generates mashup client pages including navigation controls between services and views. This system can generate ready to use codes from service specifications, so this can help to reduce the development overhead. Moreover, our approach is based on formal model and navigation patterns so the generated result code is simple and easy to understand, and includes only the necessary controls. Therefore, the proposed approach can be more effective for the case of a large number of services.

Existing employment information system is the result of a number of lists list exists is difficult to determine at a glance when a user searches for a desired jobs. The service used for the strengthening and enhancement of job satisfaction, job seekers in the problems of the existing system, there is a need to improve measures for improving the quality of the environment. In this paper, we developed a system using a mashup Jobs feature that allows users to easily and conveniently search the various regions, the conditions specific jobs you want on the web map. In this paper, we collect the RSS of employment related information from many employment information providers, and we have a mashup function that makes it easy and convenient to search various regional and conditional job information desired by the user on the web map I have developed a job information system that I used.

본 논문에서는 다양한 아두이노 무선센서 모듈과 Raspberry Pi, 웹서버를 이용한 IOT 기반 환경정보 수집시스템과 기상청 API를 통한 기상정보, 상점 서비스를 매시업하여 상품추천시스템을 구현하였다. 이 시스템은 사용자가 주변 환경의 데이터를 정확하게 확인하고 그에 맞는 상품을 추천받을 수 있도록 한다. 상품추천시스템에서는 상점 외부에 부착된 환경정보 수집시스템에서 측정한 데이터와 기상청 API 데이터를 DB에 저장하고 DB에 저장된 데이터를 이용하여 상황에 맞는 기후화면디자인과 환경정보 데이터를 html로 구성하여 보여준다. Raspverry Pi에 연결된 모니터를 통해 실시간으로 정보를 보여주며 일정 시간 간격으로 관련 상품 광고를 보여주며 필요한 물건을 추천해준다.

This paper critically investigates the cultural phenomenon surrounding the news mobile phone app in which 'curation', relying on the news editing and adaption, has become much more significant than making the news directly. This study affirms the fact that a copying culture which is basically a combinative effect of duplication (alias) and imitation(mimesis) enables us enrich the human beings' creative activities. However, we need to warn the regressive aspects of copying culture challenging the journalistic principles. This study exemplifies a case of Pikicast, which has become the most rapid growing news content mobile app in Korea. By doing a case study, this paper suggests that 'social gift' should be given to the online users as a whole. The communal and social gift would be an alternative way to the unpaid crawling of the news resources from the digital commons by the news content curating corporation such as Pikicast.

이미지 혹은 영상에 대한 자동 태깅은 해당 콘텐츠에 대한 추가적인 정보를 자동으로 시스템에 제공하는 기술로써 영상 인식, 콘텐츠 매시업, 정보 검색 등 다양한 기술/서비스 분야에서 여러 목적으로 활용되고 있다. 특히, 방송 콘텐츠는 많은 양의 정보를 제한된 영역 및 시간에 축약하여 담고 있기 때문에 영상 처리 기술을 통한 객체 인식이나, 콘텐츠 매시업, 추천 서비스 등의 성능 향상을 위해 자동 혹은 수동 태깅을 통한 정보 제공이 요구된다. 본 논문에서는 블로그를 이용한 프레임 단위의 방송 콘텐츠 태깅 기술을 제안한다. 제안하는 기술은 기존의 콘텐츠 단위의 정보 제공이나, 수동 태깅 된 정보를 제공하는 기술들과 달리, 영상의 각 프레임에 대한 자동 태깅을 목표로 한다. 제안하는 방법은 거리 학습을 통해 영상의 각 프레임이 가지는 특성을 고려한 모델을 구축한 후, 이를 토대로 영상의 프레임들과 블로그의 이미지를 매칭한다. 매칭된 결과를 기반으로 특정 블로그는 영상 내 특정 프레임 구간에 태깅 된다. 제안한 방법은 이미지 매칭 성능을 측정하여 평가하였다. 블로그 이미지에 대해 Top 1 매칭 프레임을 살펴본 결과, 70%의 정확률을 보였다. 소프트 매칭(Top n)의 경우, 최대 90%의 성능을 얻을 수 있음을 실험을 통해 알 수 있었다.

Intelligent Transportation Systems (ITS) is aimed to implement IT(Information Technology) to develop the next-generation transportation system in order to improve traffic conditions. In order to provide traffic information, the methods that provide available traffic informations to the public are needed. In this paper, analysis of the transportation applications in smart-phone and currently available methods of traffic information's sharing and providing were discussed. Finally, OPEN API was discussed and shows its effectiveness for transportation information area especially in smart phone.

To provide context aware service, certain phenomena and situation information of the user should be detecting and monitoring using sensors. But, the sensor data has heterogeneity about system, syntax, structure, and semantics. So, it is difficult to apply to various services. To solve this issue, we should remove these heterogeneities and convert to context information that is easy to provide context aware services. Also, the existing context aware service mash-up environment require relevant sensor type, criteria of context, programing ability to define the service situation. So, it is difficult to create service for a non-technical user. Therefore, we propose ontology based user-centric service environment to provide context aware IoT services. It provide context awareness and user-desired services using data that acquired via IoT paradigm. The proposed environment consist of the ontology based semantic sensor data processing and the user-centric service environment. It provide convert the object data to the context information and service mash-up process to create user service in easy way.
