Many cities in the world have increased initiative to realize smart tourism. There are unexplored challenges for the people which lead and manage smart tourism projects and realize its value in tourism (we call them as 'Smart tourism initiatives'), such as orchestrating of tourism complexity, developing and sharing tourism strategy, sustaining tourism projects and innovation. Concerning these challenges, we aim to design a holistic capability maturity model for sustainable and smart tourism governance enabling sustainable tourism innovations via tackling the challenges above. We adopted Dynamic capability theory as a theoretical lens and introduced Design science research methodology in order to develop a new capability maturity governance model as a design artifact. As a result of the study, we could synthesize findings from iterations of the design research cycle based on the IT Capability Maturity Model. Our result proposes a potential capability maturity model supporting effective communication and strategic alignment for the initiatives with illuminating future paths with evaluation methods on tourism capabilities for the initiatives. Throughout this study, we contribute to the body of knowledge as well as practice by proposing a new tourism capability governance model.

In late 20th century, smart home market evolved in China, and absorbed best manpower and technology to commercialize the smart home equipment. Many foreign companies want to take possession of Chinese market, but not arrive at abundance yet. There has many reasons, but most important thing is ignoring the interaction between technical elements and spacial elements. in other words, ignoring the correlation between each industry. Korean smart home market evolved same period with Chinese, but it has balanced development in technic and application, so the commercialize and market arrived at poverty. In this study, survey the present situation of smart home about Korea and China, and compare the technical elements. In addition to analysis the interaction between smart spacial contents and technology. This study focused on the smart apartment, and analysis the strength and weakness in each country, and make theoretical basement for Korea to make certain about Chinese smart home market.

Recently much attention in building smart factory has been dramatically increased. Despite the growing interest in smart factory, few practical guidelines exist how to successfully build smart factory. The purpose of this study is to postulate and develop a road map for building successful smart factory. To enhance mundane realism, we design the road map through University-Industry research collaboration. Specifically, drawing analysis of University-Industry research collaboration, we design a prototype and detailed road map or building successful smart factory. Moreover, we apply the road map into actual smart factory development. By doing so, we successfully prove the effectiveness of the road map. Therefore, this study provides the valuable guidelines and directions to build a successful smart factory. Ultimately this study is able to help a variety of factories which establish and implement smart factory. Further, we hope that this study will be placed to be an important foundation research on behalf of smart factory building.

In this paper, a methodology was proposed to reduce the electrical level and spatial size of the smart grid with distributed generations (DGs) to a scale in which the electrical phenomena and control strategies for disturbances on the smart grid could be safely and freely experimented and observed. Based on the design methodology, a micro smart grid simulator with a substation transformer capacity of 190VA, voltage level of 19V, maximum breaking current of 20A and size of $2{\times}2m^2$ was designed by reducing the substation transformer capacity of 45MVA, voltage level of 23kV and area of $2{\times}2km^2$ of the smart grid to over one thousandth, and also reducing the maximum breaking current of 12kA of the smart grid to 1/600. It was verified that the proposed design methodology and designed micro smart grid simulator were very effective by identifying how all of the fault currents are limited to within the maximum breaking current of 20A, and by confirming that the maximum error between the fault currents obtained from the fault analysis method and the simulation method is within 1.8% through the EMTP-RV simulation results to the micro smart grid simulator model.

Smart Work is a way of working independent of time and space restrictions with the help of ICT. For past years, Korea has been promoting Smart Work to boost ICT industry, to overcome low birth rate and population ageing, and to implement Smart Korea. Three elements of Smart Work include people, technology and space. A lot of research has been performed on people and technology for Smart Work. But it is hard to find research on space. In this paper, some representative smart work centers(SWCs) in Korea were selected and analyzed from the perspective of spatial design including general characteristics, personal spaces, group spaces, and support spaces. From this research, it is observed that current SWCs in Korea are good in providing personal work spaces and simple group meeting rooms as well as ICT environments. However, they lack of openness to the public and group spaces to encourage informal communications. It is also observed that personal space plans need to be multi-functional, and that novel supporting spaces are required to improve quality of life and creativity of workers.

With the advance of Smart TV technologies, TV watchers can enjoy the Internet and games while watching TV programs. Besides retrieving with some keywords in the Internet, people may want to access local information such as notifications from town, messages from children's schools, shopping information from local marts, and even reminder messages for visiting from hospitals while watching TV without using web-browser. In this paper, we introduce the daily life notification service scenarios and its functional and non-functional requirements. Furthermore, we also propose a system that provides the notification services, consists of smart TV apps and server systems. We also introduce the system architecture and the component design of the system. Our work will help smart TV service developers because this paper will give them some service scenarios, requirements, and system architecture and its component design.

A smart phone is a multimedia device that is a necessity for modern people. It includes a wireless networking system to share information and pictures. However, numerous smart phones are discarded every year, since they have a very fast technology development cycle. This paper presents the development of a telemetry algorithm to measure displacement and strain with a discarded smart phone and digital image correlation methods. To implement the measurement algorithm, the LabVIEW 2010 program development platform was used. In order to verify reliability, an open hole tension test was conducted using a smart phone and a universal test machine. In addition, the measurement results from the smart phone were compared with FEM analysis results.

본 연구에서는 블루투스를 이용하여 스마트폰 으로 제어되는 Smart Diffuser 디바이스의 초기모델을 개발하였다. Smart Diffuser는 디바이스에 주입하는 오일을 분사시키기 위해 초음파 진동자를 이용하였다. 고휘도 LED를 사용하여 오일이 분사되는 동안에 색상 변화가 보여 지도록 디바이스를 개발하였다. 휴대용 디바이스인 점을 감안하여 충전 시간 문제를 해결하기 위해 40mAh의 Li-Po 배터리를 사용하여 장시간 사용할 수 있도록 설계를 하였다. Bluetooth Low Energy를 이용하여 저전력 구동을 구현을 함으로서 초기 설계모델의 유용성에 대해 확인 하였다.
