In this paper, we adopt a concept of UCM(User Created Market) to develop STOWAR system which is user can use their smart phone at anytime, anywhere to directly forming a market at virtual space and other's also can access to this market trade with other users. This system is optimized for effectiveness of information alert and ease way to access information by selective event notification feature which can expected with activation of service.

소셜 네트워크 서비스의 발달로 지역적으로 의미 있는 사회적 현상이나 재난, 사건 사고와 같은 이벤트와 관련된 정보들이 대량 생성됨에 따라 이벤트의 발생위치를 추론하는 연구가 진행되고 있다. 본 논문에서는 소셜 네트워크에서 실시간적으로 발생하는 이벤트를 검출하고, 이벤트가 발생한 지역을 추론하는 기법을 제안한다. 사용자의 관계를 고려하기 위해 사용자간에 주고받은 트윗 메시지인 멘션(mention)내용을 반영함으로써 이벤트가 발생한 지역을 보다 정확하게 추론하는 기법을 제안한다.

In the age of global competition, city brand is a significant element for establishing a city's competitiveness. City branding is the process of building a storytelling about cities' content. Among the various contents that differentiate cities, this study seeks to discuss the role of an event and a city brand in the process of city branding based on the city marketing and event tourism literatures. This research uses grounded theory and a case study to examine Seoul exploring the changes in the Hi Seoul Festival and the Hi Seoul city brand over the last two decades. The qualitative research includes a secondary data analysis based on case studies from domestic and foreign regions and their festivals. The analytical results indicted three limitations: inconsistency, a lack of identity, and political leverage. Based on the limitations, this study discusses the importance of the connection between city identity and event content, suggesting implications for moving forward toward a stable Seoul city branding strategy for the Seoul Metropolitan Government.

Recently big-sized hospitals showed their interest in medical information event monitoring system based on Sense and Respond in order to give patients in emergency a safer medical treatment. In this paper we implemented medical information event monitoring system based on Sense and Respond which stand on event and monitoring process. This system consists of event definition, event extraction, event delivery, and monitoring. It ensures real-time response by grasping and delivering medical information in real-time, and well-balanced understanding of information for hospital management by real-time tracking. Also early confrontation case by case by, event delivery make the safety of patients be secured, the efficiency of hospital can be maximized by early grasping the problems in hospital management problems.

As the usage of social network services increases, event information occurring offline is spreading more rapidly. Therefore, studies have been conducted to detect events by analyzing social data. In this paper, we propose a graph based event detection scheme considering user interest in social networks. The proposed scheme constructs a keyword graph by analyzing tweets posted by users. We calculates the interest measure from users' social activities and uses it to identify events by considering changes in interest. Therefore, it is possible to eliminate events that are repeatedly posted without meaning and improve the reliability of the results. We conduct various performance evaluations to demonstrate the superiority of the proposed event detection scheme.

As touch-screen mobile phones pour into the market, demands for reusing existing mobile game contents by adding a touch-screen interface are increasing. But, the contents which are developed in existing does not have touch-screen interface and in order not to be automatic is difficult with touch- screen contents to convert. From the present paper uses keyboard interface information about the mobile game contents which does not have touch-screen interface and creates touch-screen interface with automatic the method which proposes. This method analyzes the type of key events which are used from the contents the screen keyboard layout of optimum and construct. And, key event where is confronted with automatic occurs about touch screen event and creates the screen interface which executes the keyboard event handler. In the end, experiment leads and the screen interface which has become optimum anger to the contents creating, confirms.

본 논문에서는 운행중인 차량이 수집한 위치별 교통 이벤트 (지체, 정체, 사고, 노면상태 등)를 다른 운행 차량과 실시간으로 공유하여 안전운행 서비스를 제공하기 위한 방법을 제안한다. 운행중인 차량은 차량내의 스마트 기기나 전용 기기를 이용해 수집한 교통이벤트를 실시간으로 서버로 전송하고 서버는 전송된 교통이벤트를 위치별, 시간별로 색인하고 중복된 교통이벤트를 분류하여 저장한다. 이런 모든 과정은 처리 속도 향상을 위해 Spark의 RDD를 이용해서 인-메모리에서 처리된다.

Based on a complex event processing technique, an abuse pattern monitoring method is developed to provide an real-time detection. CEP is a technique to find complex event pattern in a massive information system. In this study, the events occurred by game-play are observed to be against the rules using CEP. User abuse patterns are pre-registered in CEP engine. And CEP engine monitors user abuse after aggregating the game data transferred by game logging server.
