Five smart grid projects was started with large scale at Jeju Island in South Korea from 2009, and smart-grid test-bed was started in Nov. 2010. The five projects are Smart Power Grid (SPG), Smart Renewable (SR), Smart Transportation (ST), Smart Place (SP) and Smart Electric Service (SES). Korea government constructed the smart grid public relations center at Nov. 2010 in Jeju Island and there will be continued the field operation and interface testing among five smart gird projects until May. 2013.

Where is a better place to live? In the coming era, this should be more than simply a livable place. It should be an adaptable place that has a flexible system adaptable to any new situation in terms of diversity. Customization and real-time operation are needed in order to realize this technologically. We expect a smart city to have a flexible system that applies technologies of self-monitoring and self-response, thereby being a promising city model towards being a better place to live. Energy demand and supply is a crucial issue concerning our expectations for the flexible system of a smart city because it is indispensable to comfortable living, especially city living. Although it may seem that energy diversification, such as the energy mix of a country, is a matter of overriding concern, the central point is the scale of place to build grids for realizing sustainable urban energy systems. A traditional hard energy path supported by huge centralized energy systems based on fossil and nuclear fuels on a national scale has already faced difficult problems, particularly in terms of energy flexibility/resilience. On the other hand, an alternative soft energy path consisting of small diversified energy systems based on renewable energy sources on a local scale has limitations regarding stability, variability, and supply potential despite the relatively light economic/technological burden that must be assumed to realize it. As another alternative, we can adopt a holonic path incorporating an alternative soft energy path with a traditional hard energy path complimentarily based on load management. This has a high affinity with the flexible system of a smart city. At a system level, the purpose of all of the paths mentioned above is not energy itself but the service it provides. If the expected energy service is fixed, the conclusive factor in choosing a more appropriate system is accessibility to the energy service. Accessibility refers to reliability and affordability; the former encompasses the level of energy self-sufficiency, and the latter encompasses the extent of energy saving. From this point of view, it seems that the small diversified energy systems of a soft energy path have a clear advantage over the huge centralized energy systems of a hard energy path. However, some insuperable limitations still remain, so it is reasonable to consider both energy systems continuing to coexist in a multiplexing energy system employing a holonic path to create and maintain reliable and affordable access to energy services that cover households'/enterprises' basic energy needs. If this is embodied in a smart city concept, this is nothing else but smart energy inclusion. In Japan, following the Fukushima nuclear accident in 2011, a trend towards small diversified energy systems of a soft energy path intensified in order to realize a nuclear-free society. As a result, the Government of Japan proclaimed in its Fifth Strategic Energy Plan that renewable energy must be the main source of power in Japan by 2050. Accordingly, Sony vowed that all the energy it uses would come from renewable sources by 2040. In this situation, it is expected that smart energy inclusion will be achieved by the Japanese version of a smart grid based on the concept of a minimum cost scheme and demand response.

The main function of station is supplying the convenient environment to the passengers as a vehicle waiting place. Smart station is networked based on the station which has been combined with additional functions like effective operation and real time monitoring and power control. Smart station network for the operation has been concerning about the communication security and the data transmission distance between vehicle and station. Smart station can be useful for the ubiquitous data communication place where the people can use their personal communication instruments very easily and quickly. This is the smart station.

최근 네트워크 환경이 확장되면서 스마트 기기 보급이 지속해서 증가하고 있다. 스마트 폰, 스마트 패드, 웨어러블 등 스마트 디바이스의 보급을 통해 스마트기술과 IT융합 기술에 많은 변화를 주고 있다. 스마트기술의 발전은 4차산업 기술의 핵심적인 요소이다. 4차산업 혁명은 IT융합과 스마트 디바이스를 이용하여 주거, 산업, 생산 환경에 지능적 요소를 추가하여 새로운 서비스 기반 산업을 확장 시켰다. 스마트 홈, 스마트 팩토리, 스마트 팜, 스마트 헬스케어 등 스마트기술을 이용한 다양한 서비스 제공에 관한 연구가 활발하게 진행되고 있다. 특히 스마트 홈은 사물인터넷 기기의 보급 확산과 센서 기술, 컨트롤 기술, 애플리케이션, 데이터 관리, 클라우드 서비스 성장에 따라 급성장하고 있다. 스마트기술을 이용한 스마트 홈 서비스는 거주자에게 편리하고, 유익한 서비스 및 환경 제공이 가능하다. 스마트 홈 서비스는 기존 홈 네트워크 서비스 문제점을 보완했지만 여전히 미비한 점이 많이 있다. 즉 스마트 디바이스 보급과 공급자 위주의 서비스 개발 및 서비스 연동은 사용자 환경과 사용자 상태를 고려한 서비스 제공에 한계를 가지고 있다. 이러한 문제점을 보완하기 위해 본 연구에선 고령자 상황을 고려한 스마트 홈 서비스 시스템을 제안한다. 제안방법은 기존 스마트 홈 서비스 제공 방법에 고령자 상황과 상태 정보를 반영하여 서비스를 지원한다. 또한, 서비스 지원 확장을 통해 지역 서비스 및 외부 서비스를 적절하게 지원하여 사용자에게 적합한 서비스 제공을 목적으로 하고 있다.

China has already entered the aging society and is predicted to become a super-aged society in 2020. The recent studies identified that the elderly has more interest in 'Aging-in-Place' which emphasizes deinstitutionalization since welfare facilities such as care homes and silver towns have separated the elderly from their local communities where they used to live in. The aim of this research is to propose a promising way for smart housing services who support the elderly's living in their homes, China. This research is to investigate the elderly's life and to identify their demands on housings for implementing such smart services. The elderly's living in apartments in Luoyang city, China, were investigated through interviews using a questionnaire survey. The results show that smart housing services should be provided to support the elderly's health, safety, leisure activities, comfortable living, and social relationships sustainably. In addition, such smart housing services should be intuitive since the elderly need to use easily smart services for their autonomous life in their homes. The smart housing services should be developed in the direction of enhancing the elderly's healthy and desirable life, and lessening their discomforts due to aging.

기업은 유능한 인재가 경쟁력임을 인식하고 조직구성원의 직무교육에 관심과 투자를 확대하고 있다. 하지만 그동안 기업교육은 대기업 중심의 이러닝을 중심으로 확대 되었으며 중소기업은 그 경제적 위상에도 불구하고 상대적으로 영세한 사업규모, 직원의 잦은 이직 등으로 관심과 투자가 부족하였다. 본 논문은 스마트 기기의 보급과 확산, 지식기반 경제의 확대 속에서 중소기업의 직무교육을 혁신 과정의 중요한 부분으로 인식하고 효율적인 교육학습 방법으로 스마트러닝을 제안한다. 그리고 이에 대한 중소기업의 이용의향과 세부 효용, 속성별 선호도를 컨조인트 분석을 통해 살펴보았다. 분석결과 중소기업은 스마트러닝 수용에 긍정적인 평가를 나타내고 있었으며, 요금 지불에 대한 이슈와 교육장소가 중요하게 고려되고 있었다. 특히 서비스 개별 속성 및 수준에 대한 일반직원과 교육담당자의 인식차이 가운데 학습 기기뿐만 아니라 교육학습 방식의 혁신으로 양방향 및 맞춤형 콘텐츠에 대한 관심이 필요함을 보여 주었다. 스마트러닝은 향후 중소기업의 변화와 혁신파정에서 차별적인 가치혁신(Value innovation) 전략의 하나로서 기업의 흡수역량(Absorptive capacity)을 향상 시키는 전략적 수단으로 활용될 필요가 있다.

Considerations of how to facilitate aging-in-place(AIP) are becoming increasingly pertinent as care-givers are overwhelmed by an aging population. Aging friendly home-care services combined with IT can satisfy the needs of the elderly suffer from chronic diseases such as depression and dementia. Therefore, we propose future smart phone services and application technologies which can estimate emotional states of the aged and respond to the desire to be happy with mental health, connectedness and consolation from peoples. Firstly, we introduce depression measurement techniques to estimate the severity of depression using multiple sensors. At second, the emotional responding services are categorized to four parts and the details are described. Lastly, we propose the process to implement emotional communication and the application techniques(services) to fulfill the emotional satisfaction and mental healthcare for AIP using smart phone as a mediator.

The concept of Smart Specialization represents a major shift in EU structural policy. It recognizes place-specific qualities and particularly locally embedded knowledge to stimulate innovative economic performance. Although there have been debates about the role of universities as innovation incubator, deliberations about their influence in regional innovation strategies (RIS3) in the context of smart specialization approaches are still under-represented. This paper therefore aims at discussing the potential role of universities and related incubator environments in smart specialization strategies, which is illustrated with the help of a German state, Mecklenburg-Vorpommern.
