Connectivity is becoming more important keywords recently. For example, many devices are going to be connected to the internet. It is usually called as the IoT(internet of things). Many IoT devices can be evolved as a part of giant system of the world wide web. It is a great opportunity for us, because many new services can have emerged through this paradigm. In this paper, we propose a device virtualization framework for smart home service. The proposed framework connects the many home appliances devices and the internet using a dynamic protocol conversion. After our protocol conversion for device virtualization, our framework provides a RESTful API to access the resources of device through the internet. Therefore, the proposed framework can provide a variety of services, so it also can be developed into the ecosystem for smart home service. The current framework version only supports UPnP enabled devices of the home, but it can easily be extended to many other home middleware solutions. To verify the feasibility of the framework, we have implemented several service scenarios.

The purpose of the study focuses on increasing dangers of using smartphones while driving recently, and then is to come up with measures to reduce traffic accidents caused by using devices like a smartphone. This study conducted a survey of drivers using their smartphones while driving to understand risks caused by using a smartphones while operating vehicles. Results showed that a lot of activities may lead to distracted driving, such as texting, making phone calls, using GPS or road maps, game, etc. In this paper, we presented that functions of smartphone should be controlled partially while driving for safe driving performance. These results suggest that using IoT-based smart devices like a beacon and a smartphone application implemented, tentatively called "Safe driving solution", while driving can reduce traffic accidents. Thus, in order to effectively prevent dangerous driving due to the use of smartphones, a "Safe driving solution" which restricts all functions except for calls and driver assistance functions is suggested.

In order to monitor the growth environment of new varieties of crops, it is necessary to build the agricultural production infrastructure and strengthen the agricultural resource management system using popular smart sensor tag technology. In addition, the infrastructure for improving high-quality new varieties of crops using IoT technology and the monitoring system must be strengthened. In other words, widespread smart sensor (RFID UHF Sensor Tag) technology for environmental monitoring required for improving new crop varieties is desperately needed in the smart farm environment. Therefore, in this paper, we implemented an integrated sensor that can implement smart tag functions based on heterogeneous integrated sensors. In addition, we developed a technology that can manage crops in real time through the implemented smart integrated tag and smartphone linkage. For this purpose, an integrated antenna capable of RFID and Bluetooth communication was constructed. In addition, a communication method that allows information to be collected directly from the smartphone through the Bluetooth function was used.

Our research is for development of smart object in WBAN environment. Too many smart object in various computing device were developed, but users always attention to their lot of smart objects and any personal things now. So we need smart object that classification and management all of user's personal devices and any effects in invisible and seamless system. We discussed how develop do that object in WBAN(Wireless Body Area Network) system and how make components in this system to wireless network in this paper.

본 논문에서는 최근 황사 및 미세 먼지 등으로 늘어나는 환경적 오염으로부터 어린이들이 올바른 마스크 사용을 할 수 있도록 스마트 기능이 포함된 마스크를 제안하는 것이다. 제 4차 산업혁명으로 인하여 사물인터넷이나 스마트 제품은 날로 급증하고 있는 추세이다. 따라서, 어린이들이 많이 사용하는 마스크 제품에 스마트한 기능을 넣고자 한다. 스마트 밴드를 통해 미세먼제 오염도를 측정할 수 있고, 호흡 상태를 파악하고 분비물의 상태를 분석할 수가 있다. 따라서 의료기관을 방문하기 전까지 어린이들의 건강상태를 보다 즉각적으로 파악할 수가 있다.

본고에서는 스마트폰과 스마트TV 등과 같은 커넥티드 디바이스(connected device)에 관한 ICT 생태계(이하 '스마트 미디어 생태계')에 대해 알아본다. 스마트 미디어 생태계는 플랫폼을 중심으로 가치가 창출되는 생태계라는 특징을 가진다. 특히, 양면시장(two-sided market)에서 관찰되는 직/간접적 네트워크 외부성(direct and indirect network externality)에 의해 작동된다. 또한 단일 기능요소보다는 여러 사업자로부터 제공되는 기능요소들의 복합체인 플랫폼 연합체(platform coalition)로 출발한다. 이에 따라 생태계 초기에는 생태계 간 경쟁과 더불어 생태계 내에서 메타 플랫폼(meta platform)의 지위를 획득하려는 지배구조 경쟁도 전개된다. 스마트 미디어 생태계의 특성과 진화과정 및 운영원리에 대한 이해는 생태계 참여자들의 전략과 생태계 활성화를 위한 정책방향에 시사하는 바가 크다.

By the dissemination of the electronic blackboard systems, smart devices, and digital contents, the Korean government is recently conducting the project that replaces the classic education which utilizes paper textbooks with SMART education using various devices. Also, teachers in the field must be easily able to use SMART education infrastructure for the activation of SMART education. Especially, since the electronic blackboard is expected as a education device which will be most common for teachers, the writing software operated on the this device must supports a simple interface. And the usage of it must be simple. In this paper, we developed the writing software for the electronic blackboard which everyone can use easily. Our writing software supports the basic writing function, the human gesture recognition function which recognizes the user gesture and performs works corresponding with that gesture, and the automatic button alignment function based on the frequency of the usages.

This study intends to present the most optimal interaction in association with available functions if the foldable display is applied to smart devices. For this, I have looked into the flow of development, morphological features and the application areas of the foldable display based on review literature. I have also established five principles of interaction applicable to the foldable display through the study on the concept and characteristics of foldable display interactions and previous research cases. Next, I have conducted user surveys to find the most optimal interactions with the functions of smart devices taken into account. Prior to user surveys, I have classified foldable display interactions into 36 categories based on the five interaction principles of the foldable display. In addition, I have selected 17 major functions of regular smart devices based on relevant documents. Lastly, utilizing concrete interaction methods and functions obtained in this manner, I have conducted user surveys based on the relationship among multiple relevant factors and chosen the interaction method that acquired the highest frequency and score as the most optimal one whose detailed description has been provided as well.

This paper predict user acceptance of smart clothing. The present research develops and validates new products for smart clothing. Studies suggest that further analysis of the process be undertaken to better establish properties for smart clothing, underlying structures and stability over innovative technologies. The findings reported in this paper should be useful methods which identify user needs. such findings in now provide a way to explain technology acceptance. Both of qualitative and quantitative methods, were applied to this study in order to find out user needs for smart clothing. We are writing scenarios and conducting both focused group interviews and a survey to assess the user's interest. The purpose of the survey is to evaluate the importance of the functions and to evaluate the degree of the participant's feeling and attitude. Furthermore, we explore the nature and specific influences of factors that may affect the user perception and usage.

The recent increase in smartphone usage has ignited the development of new applications which have changed the way of living in this internet era in the world. Almost all users which have smartphone have used many kinds of applications for lots of part. Especially, Social Network Service is the most popular part for smartphone users. The greater part of smartphone users take messenger service for smartphone. This kinds of applications provide to manage as deactivation of user or change of device. When users take to manage their information, their information would be deleted securely. If secure deletion didn't work correctly and released, their personal information can be easily abused to by others through various means such as internet phishing. In this paper, we analysis that the messenger application's management function keeps on the Personal Information Protection Act and suggest to prevent legally and technically for user's personal information and privacy.
