The purpose of this study is to examine problems and status quo of the smart media addiction prevention system and to develop convergence policies to improve those systems. Based on the literature review, notable results are as following; Since current facilities including Internet Addiction Prevention Center, Korea Youth Counselling and Welfare Institute, and I Will Center, tend to focus on restricting use of smart media, efforts from various ministries have not worked properly. Therefore, there needs to be more specified and customized services based on regions and ages. Following the precedent set by advanced countries, this study suggest alternative policies to help solving the problem including recommending responsible use of social media through education rather than regulations only, encouraging family participation and intervention, expanding harmful environment block system, and establishing a partnership between local government and private organizations under central government's control. Since smart media addiction is emerging concern, further researches will be needed for developing the Korean standard for prevention policy.

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.

Even though attempts are made to transform from 2D CAD to BIM representation for building design and construction, it were not so successful for practical implementation until recently in construction industry in Korea. However, there is a dramatic change for the use of BIM by collaboration among government, independent organizations as well as industry itself. Government reckons that BIM is an important tool for environment friendly construction and industry competitiveness. The government not only makes national BIM standards and push policies in order to make market environment. Independent organizations such as BuildingSMART Korea does active role to stimulate the transformation process successfully. They act as opinion leaders for the Government to consider BIM implementation for industry competitiveness issue. They make roadmap as well as technical standards and guidelines. It also leads technical developments and supports for its implementation. Government supports researches for the implementation of BIM. The research includes BIM standards, guidelines, linking with existing Architectural Administrative Information Systems, making libraries as well as education. Government makes policy for BIM as a compulsory data for bidding process of newly designed government buildings. Private sector not only agrees BIM as a tool to adapt but also essential methods for its survival in domestic and foreign construction market. Architectural design companies and constructions companies currently develop technical skills and implement BIM for new projects such as Dongdaemoon Plaza that cannot be successfully drawn by conventional methods.

The purpose of this study was to estimate the economic evaluation of a smart farm investment for tomatoes and strawberries. In addition, the potential adoption rate of the smart farm was derived for different scenarios. This study analyzed the economic evaluation with the net present value (NPV) method and estimated the adoption potential of the smart farm with the trade-off analysis, minimum data (TOA-MD) model. The results were as follows: The analysis of the net present value shows that the smart farm investment for the two crops are economically feasible, and the minimum prices for the tomatoes and strawberries should be 1,179 and 3,797 won/kg to secure a sufficient economic feasibility for the smart farm investment. Next, the analysis of the potential adoption rates for smart farms through the TOA-MD model showed that when the support ratio for the adoption of a smart farm system was 50% and the price increase rates were, respectively, - 5, 2.5, 0, 2.5, and 5%, the conversion rates for tomato farms to switch to smart farms were 0.97, 1.78, 3.05, 4.91, and 7.47%, while the ratios of the strawberry farms to switch to smart farms were 0.12, 0.29, 0.65, 1.33, and 2.53%, respectively. This study has some known limitations, but it provides useful information on decision making about smart farm adoption and can contribute to government policies on smart farms.
