The growing literature on smart tourism and the increasing number of smart tourism initiatives demonstrate that the idea of smart tourism is captivating and that its potential is great. However, its concrete implementation so far has lacked the transformative focus called for by smart development principles. This paper suggests that conceptualizing smart tourism development as a utopian endeavor that requires critiquing the status quo and collective imagining of better tourism and good destinations could help smart tourism efforts transcend their instrumental, short-term, and fragmented character. It further introduces the concept of the Smart Tourism Mindset to propose that, as a utopian enterprise, smart tourism needs to be guided by specific values and traits that permeate actors at all levels. The paper concludes by calling for a greater focus on identifying what these values and traits are and how to best establish and communicate the Smart Tourism Mindset.

One of the major factors influencing the phenomenal growth of the smart phone market is the active development applications based on open environments. Despite difficulties in finding and downloading applications due to the small screens and inconvenient interfaces of smart phones, users download applications nearly every day. Such user behavior patterns indicate the significance of smart phone applications. So far, studies on applications have focused mainly on technical approaches, including recommendation systems. Meanwhile, the issue of culture, as an aspect of user characteristics regarding smart phone use, remains largely unexamined throughout the world. Hence, the present study attempts to analyze the highest ranked smart phone applications downloaded and paid for that are ranked the highest in 10 countries (Korea, Japan, China, India, the UK, USA, Indonesia, Canada, France, and Mexico) and we then derive the CDSC (Cultural Dimensions Score of Content) for these applications. The results derived are, then, mapped to the cultural dimensions model to determine the CISC (Cultural Index Score for Country). Further, culturally significant differences in smart phone environments are identified using MDS analysis.

인류를 구할 8가지 기술 중 한가지로 스마트 그리드(Smart Grid)가 소개된 바 있다. 즉 에너지 사용의 효율성을 높여 전력량과 비용을 줄이고 전력 공급자와 소비자 간의 실시간 정보교환이 가능한 지능형 전력망이라 할 수 있다. 그러나 스마트 그리드의 취약점들로 인하여, Smart Meter가 해킹을 당해 정전으로 인한 대규모 피해가 예상 될 수 있다. 본 논문에서는 Smart Meter에 대한 취약점 분석을 실시하고, Smart Meter의 Gateway 보안을 위해서 접근제어와 인증을 통해, 사용자의 접근과 개폐에 대한 보안을 실시한다. 범죄가 발생했을 포렌식 자료를 통한 법적 책임에 관한 내용을 연구한다.

Smart Grid는 전기망과 정보통신망이 융합된 형태로 발전 송전 배전의 전 과정에 대한 통제가 가능하고, 결과적으로 에너지 사용의 효율성을 높이고자 하는 것이 지능형 전기망이다. 정보통신망을 이용하기 때문에 기존의 다양한 사이버 보안위협으로부터 그대로 노출되어 있으며, 전기망에서의 취약점도 함께 가지고 있다. 본 논문에서는 우리나라보다 먼저 Smart Grid를 도입한 나라의 Smart Grid 공격 사례와 예상 공격에 대한 취약점을 분석하고, 분석된 취약점에 대한 Smart Grid 보안 대책을 마련한다. 본 연구를 통해 Smart Grid에 대한 보안성 강화와 사회안정성 향상에 기여하게 될 것이다.

In the fourth industrial revolution era, various commercial smart platforms for smart system implementation are being developed and serviced. However, since most of the smart platforms have been developed for general purposes, they are difficult to apply / utilize because they cannot satisfy the requirements of real-time data management, data visualization and data storage of smart factory system. In this paper, we implemented an open source based smart manufacturing big data platform that can manage highly efficient / reliable data integration for the diagnosis diagnostic system of manufacturing robots.

In this paper, we describe a method for two-way communication service for smart phone integrated with pager which receive various kinds of Internet service information and pushes this information into smart phone to make it available for Internet assess. In this method, the server can push the status data of message boxes into the smart phone and it makes connection to the server automatically. The proposed method will make it possible to manage and excange the information and resources in an efficient manner during idle time, and will provide the potential capabilities of developing a variety of new Internet services for the system.

Unity programs are largely recognized as game development tools. However, it has many functions built in, so it can be applied to various fields as well as game development. Therefore, in this paper, we propose a smart farm environmental control program using Unity and Photon. The proposed program has vast compatibility that is not limited to specific devices, and it is very easy to build network systems for remote control. In addition, the proposed programs were installed on various devices such as pc and smartphones, making it easy to control the smart farm environment system. Through experiments, it was confirmed that data transmission and reception between Windows and Android, other operating system environments, and that smart farm systems were operating normally.

We see an energy fucused smart city evolution of the UK along with the project of "Smart London Plan (SLP)." A theoretical logic of business model innovation has been discussed and a research framework of evolving energy focused smart city is formulated. The starting point is the silo system. In the second stage, the private investment in smart meters establishes a basement for next stages. As results, the UK's smart energy sector has evolved from smart meter installation through smart grid to new business models such as water-energy nexus and microgrid. Before smart meter installation of the government, the electricity system was centralized. However, after consumer engagement plan has been set to make them understand benefits that they can secure through smart meters, the customer behavior has been changed. The data analytics firm enables greater understanding of consumer behavior and it helps energy industry to be smart via controlling, securing and using that data to improve the energy system. In the third stage, distribution network operators (DNOs)' access to smart meter data has been allowed and the segmentation starts. In the fourth stage, with collaboration of Ofwat and Ofgem, it is possible to eliminate unnecessary duplication of works and reduce interest conflict between water and electricity. In the fifth stage, smart meter and grid has been integrated as an "adaptive" system and a transition from DNO to DSO is accomplished for the integrated operation. Microgrid is a prototype for an "adaptive" smart grid. Previous steps enable London to accomplish a platform leadership to support the increasing electrification of the heating and transport sector and smart home.

IT environment gets more complicated in terms of open platform, network standards, device design and hardware, etc. Smart network and application are in the fields of corporate as well as national competition for future fusion technology. In development environment focused on computers, the ideas of authoring tool have been presented in terms of improved software productivity. In smart environment where subdividing works are consecutively done, current authoring tool should be effectively updated for effective development of programs and easier access to business works. The basic concept of a new conceptual App development tool, Smart App Authoring Tool, which has been designed in this study and enables to apply on-site requirements to smart phones, is to develop Apps on the level using easy-to-learn Word or Excel in a computer. Therefore, this study is intended to design a conceptual Smart App Authoring Tool to optimize the cost and time for developing and maintaining new application services under various smart phone platform environments. Based on the performance of smart app authoring tool herein, every people can develop a smart app program at moderate level. So this paper have designed a conceptual smart app authoring tool. This study presented educational efficiency of the authoring tool by developing business Apps under various business environments and applying them under university and high school environments.
