Internet of Media Things (IoMT) aims to provide intelligent media services to users by connecting (media) things to each other and exchanging media data. The mission given by the user is automatically executed, and intelligent media service can be provided to the user. To achieve this, ISO/IEC 23093-5 started standardization work on the mission data given by the user to the media thing and the media thing controller (MController) that controls the media things. This paper introduces the contents of ISO/IEC 23093-5.

전통시대의 문학을 생태주의적 관점에서 논의한다면 당대 지식인인 양반들과 사대부의 시조인 평시조에 나타난 자연관 정도로 생각하였던 탓에 사설시조나 서민작가는 큰 관심의 대상이 아니었다. 또한 사설시조 속의 '산것들'도 주목받지 못했다. 그것들은 시어로서는 부적절한, 이른바, '생경한 시어' 또는 '비시적 사물의 시화'라는 홀대를 받았다. 그 어떤 평자들도 그 살아 숨쉬는 것들을 '산것들'로 인식하지 않았고, 따라서 작품속의 주체적 대상으로도 인식하고자 하지 않았다. 그러나 사설시조에서는 경험적, 구체적, 일상적 동물들의 등장이 관심을 끈다. 이는 사실 양반들의 관념적 생물관과 비교될 만한 단서도 된다. 본고는 사설시조 속의 이들 '산것들'과 그들에 대한 작가의 시각과 인식에 대해 소박한 논의를 하였다. 본고에서 '산것들'은 살아 움직이는 것들을 의미한다. 먼저 사설시조 속의 '산것들'은 일상과 경험의 생물들이었다. 그것들은 더 이상 사설시조의 작가에게는 지식이나 관념적 생물이 아니었다. 생물환경적으로 도저히 공생할 수 없는 '산것들'이 함께 등장하는 것이 가능하거나 그 반대로 오랫동안 친숙한 일상경험에 근거하여 '산것들'에 대한 경험적 인식이 탁월한 작품도 있었다. 또한 '산것들'에 대한 사설시조 작가들의 친근하고도 애틋한, 그리고 우리 인간과 다를 바 없는 생명체에 대한 온기 있는 시선은 때로는 동일시의 대상으로 또 때로는 감정이입의 대상으로 파악하기도 하였다. 더러는 애증이 혼재하는 복합적 시선도 눈에 띈다. 사설시조 작가들의 삶은 온갖 '산것들'과 함께 하는 공생의 삶에 다름 아니다.

Recently, new devices have been developed for the Internet of Things concept. The devices commonly use RF (Radio Frequency) based wireless communication. With the increase in the number of devices, the space allocated for the radio frequency band in wireless communication fills rapidly. Visible Light Communication (VLC) is an alternative, secure and economical communication technology that uses light instead of radio frequencies. While Web of Things (WoT) is the adaptation of the experience and knowledge acquired from the web into the internet of things ecosystems. By combining these two technologies, the development of the Visible Light Communication for Web of Things (VLC4WoT) system, which can use VLC and WoT technologies, has been our motivation. In our study, microcontroller control circuit was created for VLC4WoT system. Control of the circuits over the internet was performed. VLC based receiver and transmitter units have been developed for wireless communication. Web based interface was created for control. The test apparatus consisting of four objects with four outputs and a transfer unit was carried out. In this test, communication was achieved successfully. It was presented in the study that VLC can be used in the web of things architecture. In the future, it is envisaged to use this system as a safe and economical system in indoor environments.

본 연구에서는 도서관에 사물인터넷(Internet of Things) 개념을 적용하여 사람, 사물, 데이터 등의 정보가 서로 유기적으로 연계되는 생태학적인 네트워크 공간으로서의 해석을 시도하였다. 먼저 도서관의 물리적 공간에 존재하는 다양한 사물과 인터넷 공간에 존재하는 데이터를 사물인터넷 요소로 정의하였다. 다음으로 다양한 사물들이 상이한 메타데이터와 통신 프로토콜을 통해 정보를 교환하고 유용한 정보로서 서로 통합하기 위한 시맨틱 웹 기술 적용을 제안하였다. 마지막으로 인터넷 공간속에서 다양한 사물인터넷의 요소들이 실시간으로 공유하는 정보를 도서관 관리 및 이용자 서비스 등 특정 목적에 활용될 수 있는 방안으로서 사물인터넷 모델을 제시하고자 하였다.

Internet of Things(IoT) is electronic devices and household appliances use wireless sensor network in environment of high speed wireless network and LTE mobile service. The combination of the development of Internet and wireless network led to development of new forms of service such as electronic devices and household appliances can connect to the Internet through various sensors and online servers such as a Home Network. Even though Internet of Things is useful, there are problems in Internet of Things. In environment of Internet of Things, information leakage could happens by illegal eavesdropping and spoofing. Also illegal devices of wireless communication interference can cause interfere in Internet of things service, physical damage and denial of service by modulation of data and sensor. In this thesis, it will analyze security threats and security vulnerability in environment of mobile services and smart household appliances, then it will suggest plan. To solve security issues, it is important that IT and RFID sensor related companies realize importance of security environment rather than focus on making profit. It is important to develop the standardized security model that applies to the Internet of Things by security-related packages, standard certification system and strong encrypted authentication.

최근 사물 인터넷(internet of things) 기술은 클라우드 컴퓨팅 서비스(cloud computing service) 및 빅 데이터(big data)와 함께 IT분야에 이슈가 되고 있는 기술 중에 하나로, 다양한 산업분야에서 응용 및 활성화되고 있다. 이러한 동향은 유비쿼터스(ubiquitous) 시대를 실현하는데 중요한 기반 기술의 등장이라 할 수 있다. 그러나 사물 인터넷은 다양한 산업분야에서 실현되고 있는 만큼 보안 문제 또한 다양할 것으로 예상되고 있는 가운데 이에 대한 보안 위협(security threats)들에 대한 대응 방안이 강구되어야 할 것이다. 따라서 본 논문은 사물 인터넷 기술의 적용분야에 대한 사례와 이에 따른 보안 위협들을 분석해 봄으로써, 향후, 사물 인터넷의 보안 대응 방안 마련에 활용될 것으로 기대한다.

In this study, we developed a Hedonic Model for Retargeting Advertising Based on Consumer-centerd IoT space for offering useful, interest, and interactive information to consumer. And most existing relative researches about Internet of Things but, this paper focusing on the Type of information, humor, and interactive and analyze the attitude and clicks intention to Retargeting Advertising Based on Consumer-centerd Internet of Things. According to the results, humor Advertising is positively related to attitude and click intention toward Internet of Things Advertising. But information Ad and interactive Ad affect positive to click intention. This is mean that click intention is more immediate reaction of consumers in the IoT space. Therefore Future research will be designed in a more interactive elements that can lead to positive reaction of consumers on the Internet of Things be more effective if you advertise advertising.

Recently, Internet of Things (IoT) have become popular for research and development in many areas. IoT makes a new intelligent network between things, between things and persons, and between persons themselves. Social network service technology is in its infancy, but, it has many benefits. Adjacent users in a social network tend to trust each other more than random pairs of users in the network. In this paper, we propose recommendation technique using social network in Internet of Things environment. We study previous researches about information recommendation, IoT, and social IoT. We proposed SIoT_P(Social IoT Prediction) using social relationships and item-based collaborative filtering. Also, we proposed SR(Social Relationship) using four social relationships (Ownership Object Relationship, Co-Location Object Relationship, Social Object Relationship, Parental Object Relationship). We describe a recommendation scenario using our proposed method.

Autonomous things system is a technology that judges and acts based on using surrounding information by itself, and it is evaluated as a future technology that can replace the current IoT technology. The current IoT technology is widely used from facility monitoring to machine control but it is shown weakness as a evaluation and prediction technique despite of smart city important technology. In this study, in order to confirm the application of the autonomous things technology, a monitoring system was installed on a real reservoir dam facility and long-term monitoring was performed that the measuring device itself judges and control as a facility monitoring technology. The autonomous things technology was confirmed during 19 months and it is possible to continuous measurement in the same way as current automated instrumentation. In addition, it was confirmed that the ICT device itself could to control autonomously measurement cycle according to the rainfall by itself.
