Purpose: The purpose of this study is to support SMEs' introduction of smart factories during the $4^{th}$ Industrial Revolution era. Through this study, we developed the readiness assessment framework for SMEs. This study draws practical implications for improving the readiness of SMEs to introduce smart factories. Methods: Readiness Assessment Framework Design method, Case Studies Analysis Results: This study identified SMEs suitable for smart factories and identified key issues for nonconforming companies. And the diagnostic framework has been determined whether it works in a real-life SME environment. Conclusion: In order to succeed in the smart factory deployment, readiness assessment for SMEs should be performed as necessary. Prior to the introduction of smart factories, quality innovation activities should be carried out according to factory level.

In this paper, we introduce a smart city-cyber-security-grid-matrix methodology, as a result of research on overall cyber security of smart cities. The identified cyber security risks that threaten smart cities and smart-city-cyber-security-threat list are presented. The smart-city-cyber-security-requirements necessary to secure the smart city cyber security with the developed smart city-cyber-security-grid-matrix are given in this paper. We show how the developed smart city-cyber-security-grid-matrix methodology can be applied to real world. For it, we interlocked the developed smart city-cyber-security-grid-matrix methodology with the cyber-security-framework of the National Institute of Standards and Technology, and developed a framework-based smart city-cyber-security-grid-matrix. Using it, it is easy and comfortable to check the level of cyber security of the target smart ciy at a glace, and the construction and operation of the smart city security system is systematized.

Existing PoS (Point of Sale) based payment frameworks are vulnerable as the Payment Application's integrity in the smart phone and PoS are compromised, vulnerable to reverse engineering attacks. In addition to these existing PoS (Point of Sale) based payment frameworks do not perform point-to-point encryption and do not ensure communication security. We propose a Smart and Secure PoS (SSPoS) Framework which overcomes these attacks. Our proposed SSPoS framework ensures point-to-point encryption (P2PE), Application hardening and Application wrapping. SSPoS framework overcomes repackaging attacks. SSPoS framework has very less communication and computation cost. SSPoS framework also addresses Heartbleed vulnerability. SSPoS protocol is successfully verified using Burrows-Abadi-Needham (BAN) logic, so it ensures all the security properties. SSPoS is threat modeled and implemented successfully.

With Internet of Things (IoT) technology, home environment becomes smarter than ever. Not only smart devices such as smart phone or smart TV, but also various IoT devices including sensor, smart thermostat, and smart scale has now become very common on the market. These devices have connectivity to the Internet, so that user can read data from the device or control the device using Internet technology. However, due to diversity of smart home requirements, device collaboration in smart home remains a challenging task still. Usually smart home is built with various technologies to fulfill its own purpose, and these purposes cover very wide area from controlling low-power sensor devices to controlling high-performance devices like smart TV and smart phone. This variety of smart home requirements makes smart home very complicated due to mixed network architecture, protocol and technology. In this paper, a framework to enable managing and collaborating heterogeneous IoT devices in smart home environment is proposed. Several programming models are defined in the proposed framework to make application development for heterogeneous devices more intuitive. The proposed framework has been implemented as a web service, and a case study with real-world smart home IoT devices is presented.

스마트 폰을 비롯한 스마트 TV 등 여러가지 스마트 기기의 보급으로 인해 스마트 기기 간의 연동에 대한 필요성이 증대되고 있다. 본 논문에서는 스마트 TV와 스마트 폰을 연동하기 위한 게임 프레임워크를 제시하고, 시범 콘텐츠를 통해 제시된 프레임워크의 효용성을 증명하였다. 스마트 기기 사이의 연결 문제는 기본적으로 이기종 간의 연결 문제로 볼 수 있다. 이러한 문제는 이기종 기기 사이의 데이터 송수신과 보안까지 고려해야 하기 때문에, 핵심적인 데이터는 클라우드 컴퓨팅 개념을 도입하여 서버에 저장하고 스마트TV에서는 이 데이터를 이용해 게임을 수행하는 형태로 작동한다. 제시된 프레임워크는 게임을 비롯한 여러 가지 관련 분야에 적용될 것으로 예상된다.

Smart-Phones are utilized in disaster management field because it can deliver disaster information to large population simultaneously and quickly, and provide accurate information through situation-based service using the LBS(Location Based Service). To study on the utilization of smart phone for disaster information collection and dissemination method, this study suggest a framework which connects smart phone by loading application for reporting disaster. The disaster monitoring and situation dissemination system framework using smart phone is composed of 4 parts. First, smart phone application enters image, video, voice and text information and location of the disaster. Second, the disaster report reception and situation dissemination server receives the information, save in the DB, and send through smart phone SMS. Third, store into disaster information database. Fourth, display the disaster report and management information on 2D GIS, support the decision making process in deciding whether to manage as disaster, and disaster management web service which disseminates situation.

The considerations of the electrical device' characteristics and the customers' satisfaction have been important criteria for efficient smart grid systems. In general, an electrical device is classified into a non-interruptible device or an interruptible device. The consideration of the type is an essential information for the efficient smart grid scheduling. In addition, customers' scheduling preferences or satisfactions have to be considered simultaneously. However, the existing research studies failed to consider both criteria. This paper proposes a new and efficient smart grid scheduling framework considering both criteria. The framework consists of two modules - 1) A day-head smart grid scheduling algorithm and 2) Real-time sudden demand negotiation framework. The first method generates the smart grid schedule efficiently using an embedded genetic algorithm with the consideration of the device's characteristics. Then, in case of sudden electrical demands, the second method generates the more efficient real-time smart grid schedules considering both criteria. In order to show the effectiveness of the proposed framework, comparisons with the existing relevant research studies are provided under various electricity demand scenarios.
