The following research has focused and implemented on designing a system that classifies the severity of mass casualty situations across both normal and disaster levels. The system's algorithm has implemented requirements such as accuracy as well as user convenience. The developed e-Triage System has applied various severity classification algorithms implemented from IoT concepts. In order to overcome flaws of currently used severity classification systems, the e-Triage System used electronic elements including the NFC module. By using the mobile application's severity classification algorithm the system demonstrated quick and accurate assessment of patient. Four different LED lamps visualized the severity classification results and RTS scores were portrayed through FND(Flexible Numeric Display) after a two wave classification.

Applying evolved IT technology to increase the satisfaction of the consumer is a typical feature of the rapidly transformed service industry. Smart devices have taken a place as the mainstream of major media, moreover, IT service strategies utilizing smart devices have been constantly developed. Location recognition method of users has been proposed as one of the significant features to the IT service industry. The long-term care home services can be one example of user location recognition methods that real time computerization of service record utilize an attached tag to home of pensioners with RFID reader or an NFC function of mobile when a home carer provides service. And, the Homecare Electronics Management System (HEMS) and the various location recognition methods will be discussed to improve effectiveness of services. In this paper, we propose a home applicable electronic management system which insurer, home care service facilities, home cares, pensioners and guardians which enables to simultaneously check service records based on the improved system by use of iBeacon.

As mobile equipments have been developed while we use public transport, several applications for knowing arrival informations of public transport have happened. But these only provide public traffic informations simply, these solving applications for problems and inconvenience that we ride/get off public transport do not exist. These inconveniences are occurred mainly on tagging card, when tag error or without advanced preparation are happened, these caused for delay while we use ride/get off. Also, these caused for traffic congestion. In this paper, in order to solve these problems, we use Beacon and we overcome narrow range of NFC and we implemented for Android application for decreasing delay while several people could ride/get off simultaneously.

This paper proposes and implements an on-line instruction manual system which can generate the instruction manual page for the target device at the smartphone on the spot. The instruction manual app. on smartphone scans a QR code or reads NFC tag attached in the instruction manual management module embedded in the target device, and receives instruction manual data from the instruction manual management module through the Bluetooth communications and finally shows the refined instruction manual pages on the smartphone display using a Web-based templates. For the evaluation we embedded the instruction manual management module for an industrial generator with its instruction manual data. Assuming a circumstance of blackout we show that the proposed system can reduce the repair work within two steps compared to three steps in the existing one without the proposed system.

Block Transporter should be optimized transportation path, otherwise it brings about lot of logistics costs and production delays. Block Transporter location must be checked in real time for optimization of transportation path. In this paper we implement real-time location determination using mobile RFID for location of Block Transporter. Mobile RFID reader mounted on a smartphone is recognize Mobile RFID Tag attached in the Transporter. Then, Smartphone is store information of every Transporter name and load and etc. Finally, Smartphone is transmit information(Mobile RFID Tag information, Transporter information, location determination information used AP and GPS) to the server. As a result, We can optimize or modify transportation path of Block Transporter in real-time using information transmitted to the server.

4차 산업혁명 시대의 도래로, 제조업 기반의 기업들은 단순히 제품을 가공 또는 조립하여 제품을 판매하는 과거의 공정 행태를 지식화하여 부가가치를 높이는 지능형 생산 체계를 도모하고 있다. 제품을 생산하는데 있어서 현대의 제조기업들은 대부분 관련 장비 또는 설비들에 대한 의존도가 높다. 본 논문에서는 이와 같은 제조 장비를 생산하고 사후관리까지 하는 일련의 데이터들을 수집하고 분석하여 장비의 고장예측부터 신규장비의 기획까지 활용할 수 있는 장비 이력관리 시스템을 제안한다.

Recently, the complexity of underground utilities has increased and it has became more difficult to identify and manage information about all underground utilities due to changes such as road extension or building relocation. As a result, number of accidents related to underground utilities caused by excavation works or disasters are in rise, and naturally damages as well are increasing due to the accidents. Therefore, there is a need for a management system capable of easily registering or retrieving information of underground utilities from a remote place. In our previous work, we have developed a utility labelling system based on NFC (Near Field Communication) tag and a utility management system based on IoT (Internet of Things). However, in general, there are diverse communication devices and protocols in IoT environment. Therefore, in this paper, we propose management system and IoT gateway that enables smooth communication even in different types of devices based on the previous our work.

U-Publication, the Tag-Embedded publication, is one of U-Media. U-Media is defined as a media where human creates and consumes content through not only human cognitive and perceptual processes but also through the interactions between surrounding digital systems. U-Media provides information by generating, collecting, and attaching the content itself and the related information based on the interaction of the bio-systems incorporating digital information and devices embedded in humans, and surrounding objects including external digital devices. Using U-Publication, readers consume its content not only in offline but also online through a mobile RFID reader which touches and connects the URLs embedded in the RFID tags attached to it. Readers can consume the additional content though the hyperlinks attached to U-Publication and perform commercial activity as well as consumer the printed content. This paper defines the RFID-Tagged publication, proposes its related business models, and evaluates the alternative business models through a simulation study.

In this paper, we propose a medication reminder system using IoT platforms and products to help old adults keep track of their medication schedule, one of 10 Korean instrumental activities in daily living (K-IADL). An interworking architecture based on the oneM2M standard platform is designed to allow various IoT products to be connected each other through interworking proxy entities. A prototype system for the medication reminder service is developed, which consists of a pair of off-the-shelf pill bottle and container box embedded with an NFC tag and reader respectively, three types of actuators including a LIFX LED lightbulb, Musaic speaker, Microsoft Band 2, and smartphone applications. The experiment shows that our medication reminder system can make alarms for old adults to take their pills appropriately considering where they are and when they have food inferred from data collected from sensors including ultrasonic sensor and rice cooker, fostering them to keep their medication routine.

The doorlock using buttons has been widely used since it does not exploit the physical key and has much functions though it is cheap. However, the doorlock has problems where it is easy to forget the secret number since the user has to remember the number and difficult to keep secure when the one secret number has been used for a long time. In this paper, we propose the doorlock system using the near field communication. The proposed system controls the open and close of the doorlock using user data acquired by the near field communication tag, The implemented doorlock system has the benefit to control the doorlock without a secret number.
