  • With the proliferation of advanced wireless network and sensor technologies, smart devices under USN(ubiquitous sensor network) environment are capable of collecting context information such as temperature, humidity, weight, and location about objects at real time. Therefore, applications must be able to analyze collected information and notify useful information to wanted users timely. This service can be realized by implementing an event-based middleware. In the middleware, event messages collected from physical environment will be filtered according to profiles that users define in advance and the result will be sent to the interested users. In this paper, we present XML-based event model, ECA-based profile model, and the architecture of an event-based middleware suitable to USN environment. We will also model and describe them using the examples of logistics area. By implementing the system based on the design above, the middleware enable applications or users to easily access to physical sources. The proposed middleware can also apply to not only logistics area but also other various areas under USN environment such as intelligent traffic control system, national disaster management system and u-medical system.

  • When cyber attacks are discovered in nuclear facilities, licensees are required to notify regulatory organizations for quick action. This also helps regulatory organizations to strengthen regulatory capabilities for cyber security. Currently the U.S. issued the final draft rule for Cyber Security Event Notifications. Domestic regulatory activities being at an early stage for cyber security need to implement law for Cyber Security Event Notifications. Since the current laws are focused on the aspect of safety, they are in need of more specific laws for cyber security.

  • 유무선 통신기기 및 센서 기술의 발달은 물류 환경에서도 화물 및 주변 환경의 온도, 습도, 무게, 위치 등의 상황 정보를 실시간으로 수집하는 것을 가능하게 한다. 또한, 사용자는 언제 어디서든 자신이 관심 있는 화물에 대한 상황 정보를 실시간으로 얻기 원한다. 이러한 요구를 만족시키기 위해, 응용은 상황 정보를 실시간으로 수집하여 분석하고, 원하는 사용자에게 전달할 수 있는 서비스를 제공하여야 한다. 이벤트 기반의 서비스는 이러한 요구를 만족시킬 수 있는 방법 중의 하나이다. 이 논문에서는 위치 및 RFID 기반의 물류 환경에 초점을 맞추어 이벤트 통지 시스템을 설계한다. 이를 위해, XML 기반의 이벤트의 표현 모델과 ECA 기반의 프로파일 정의 모델을 제시하고, 2단계로 분리된 효율적인 이벤트 필터링 기법을 제안한다. 또한, 이를 기반으로 구현된 시스템은 물류 환경뿐만 아니라, RFID나 GPS 장치를 기반으로 하는 지능형 교통관리 시스템 등에 광범위하게 적용할 수 있다.

  • In case of a emergency situation or a natural disaster, a warning notification system is an essential tool to notify at-risk people in advance and provide them useful information to survive the event. Although some systems have been proposed such as emergency alert system using android, SMS, or P2P overlay network, these works mainly focus on a reliable message distribution methods. In this paper, we proposed a novel design and implementation of a personalized warning notification system to help inform not only the at-risk people but also their family and friends about the coming disaster as well as escape plan and survival information. The system consists of three main modules: the user selection module, the knowledge based message generator, and message distribution modules. The user selection module collects the list of people involved in the event and sorts them based on their level of involvement (their location, working position and social relationships). The knowledge based message generator provides each person with a personalized message that is concise and contains only the necessary information for the particular person based on their working position and their involvement in the event. The message distribution module will then find a best path for sending the personalized messages based on trustiness of locations since network failures may exist in a disaster event. Additionally, the system also have a comprehensive database and an interactive web interface for both user and system administrator. For evaluation, the system was implemented and demonstrated successfully with a building on fire scenario.

  • The advancement and diversification of urban functions has caused an increasing need to improve the reliability of power supplies. The diversification of urban areas causes social disruptions by paralyzing urban functions during power outages. A large power outage occurs in the event of an accident, owing to the subduction of distribution lines. Therefore, in recent years, for the sake of the environment and safety, the safety diagnosis of electric power facilities has become an important issue. In this system, because thermal information changes rapidly during unattended monitoring owing to heat concentration phenomenon due to abnormal load or deterioration, studies have been conducted on the development of a device that can notify the manager at all times.

  • The use of the implantable Doppler device eases the burden of free flap monitoring, and allows caregivers to notify healthcare personnel of a potential vascular event. A 24-year-old female patient underwent anterolateral thigh adipofascial flap surgery to provide a buried flap on the left temporal area for a depressed and infected skull wound. The author was able to salvage the flap from two venous occlusions, which was made possible by early notifications from the caregiver who reported changes in the Doppler signal.

  • As the elderly population is becoming an aging society, the elderly are experiencing many problems. Social security costs for the elderly are increasing and the un-linked social phenomenon is emerging. Thus, the social infrastructure and welfare system established in the past economic growth period are in danger of not functioning properly. People socially isolated or with chronic diseases among the elderly are exposed to various accidents. Thus, an active healthcare management service is imperative. Additionally, in the event of a dangerous situation, the system must have ways to notify guardians (family or medical personnel) regarding appropriate action. Thus, in this paper, we propose the smartphone-based healthcare and emergency response service platform. The proposed service platform aggregates movement of relevant data in real-time using a smartphone. Based on aggregated data, it will always recognize the user's movements and current state using the human motion recognition mechanism. Thus, the proposed service platform provides real-time status monitoring, activity reports, a health calendar, location-based hospital information, emergency situation detection, and cloud messaging server-based efficient notification to several subscribers such as family, guardians, and medical personnel. Through this service, users or guardians can augment the level of care for the elderly through the reports. Also, if an emergency situation is detected, the system immediately informs guardians so as to minimize the risk through immediate response.

  • 사물 인터넷 기기가 일반화됨에 따라 사용자의 상황을 파악하고 다른 사용자에게 알림을 주어 위급 상황에 대처하기 위한 서비스가 증가하고 있다. 이와 같은 시스템은 대부분 기기의 값이 일정 기간 이상 변하지 않거나 이상치가 발견되면 이벤트로 판단하고 분석한다. 그러나 기기가 비활동 상태라면 상황을 파악하거나 다시 서비스를 제공할 수 없다. 이 때 만약 사용자의 요구를 파악하고 주변의 다른 기기들을 통해 서비스를 제공하거나 다른 사용자에게 상황 정보를 알린다면 적절한 조치를 취할 수 있다. 본 논문에서는 사용자의 요구를 포함한 상황 인지 모델과 이를 반영한 기기 탐색 시스템을 제안한다. 시스템은 수집한 데이터를 기반으로 사용자의 상황과 요구를 분석한다. 만약 사용자 기기가 비활동 상태일 때는 다른 기기를 탐색함으로써 상황을 인지하고 나아가 사용자에게 다시 서비스를 제공할 수 있다. 제안하는 방법을 통해 사용자 중심의 서비스 제공하고 여러 응급 상황에서 필요한 요소들을 분석, 대처한다.

  • The purpose of this study is to classify Avatar fashion style through analysis of on-line Avatar Mall and to propose color pallette and fashion contents from fashion color analysis. The literature research focused on investigating the notion, characters and types of Avatar and relation of Avatar and self-image, clothing image and color image. In data research, 4 on-line portal sites Avatar Malls were analyzed and Avatar fashion style was classified. In addition, Avatar clothing color was analyzed. The research of this study are as follows: Firstly, Avatar in the cyber space represents 'me' of the real states. Avatar fashion helps to represent Avatar Image and clothing makes human image and identity as a social sign. Color helps to constitute clothing impression and human image, therefore clothing and color are the important elements to express self-image through Avatar in the cyber space. Secondly, Avatar Malls of 4 on-line portal sites are very similar and confuse Avatar users because of no standard of fashion style classification. Accordingly, the standard of fashion style classification should be made by a fashion expert, and the specific characters of every on-line portal site should be emphasized. Thirdly, as a result of the analysis of Avatar's clothing, the clothing is divided into a real world clothing and an imaginary world clothing. There are daily clothes, uniform, event clothes, story clothes and fantasy clothes. As a result of the color analysis of Avatar clothing, White, Red, Red Purple colors and bright and vivid tone are generally used for Avatar clothing. This study is significant to classify Avatar fashion style systematically, to notify sensitive and delicate users' sign and to make Avatar fashion image emotional and high-quality.
