According to adverse effects of ecosystems due to a bulk of fossil fuel consumption, utilization of sustainable and renewable energy is required. In this paper, converting the energy crisis into an opportunity of new growth is expected by converting heat energy in asphalt pavement into electric power using thermoelectric effect. For this, experiments of inserting heat collector pipe and thermoelectric element into asphalt were performed, and the electric power of heat energy harvesting was measured for development of efficient harvesting system of heat energy. As the results of experiments, electric conversion of average 19.86W per day is possible at $1m^2$ conversion area at a depth of 5cm, and possibility of this system was confirmed. Consequently, a systematic "Green Road" using sustainable heat energy source in asphalt pavement simultaneously with environmental maintenance and econovic growth was suggested.

This article addresses potential errors in accounting greenhouse gas (GHG) emissions based on the International Council for Local Environmental Initiatives' (ICLEI's) International Local Government Greenhouse Gas Emissions Analysis Protocol (IEAP). The IEAP seems to provide practical guidelines for local governments so that they can measure their GHG emissions. The outcomes are immediately convertible for any national GHG inventory analysis when one is constructed based on the methodology drafted by Intergovernmental Panel on Climate Change. Further, it provides a societal foundation at the global level in order for local governments to collectively deal with 'double-counting' and 'allocation' problems. However, ICLEI's IEAP overlooks two major issues: (1) the protocol does not consider carbon dioxide emissions due to burning biological fuel as a type of GHG emission; and (2) it overlooks the possibility of indirect double-counting when producing emission factors at the local level. Thus, the limitations must be fixed so that the local governments can measure their GHG emissions more precisely, while the accurate GHG inventory will ultimately support reducing the local governments' emissions to mitigate anthropogenic climate change.

With the advent of smart age, the concern on smart work has gradually increased in solving our social problems including low birth, aging, low productivity and green growth with low carbon as well as encouraging the balance between work and life. In addition, the competitiveness among companies and countries to preoccupy the advanced smart work technologies which lead the economic growth in the future have increased more than ever before. So have global standard competitiveness done under the situation of using international standardization as practical strategy for dominating market. It is essential to make standardization strategy and do systematic implementation for core technology which leads global market in order to fit such an environment and introduce smart work as soon as possible. Therefore, this paper suggests standardization items which lead global standard and implementation direction on standardization through analysing the current situation introducing smart work and technology/standardization trend.

The government has made a lot of efforts to realize 'low-carbon green growth', one of the national policy agendas, throughout the whole industries. The construction sector is not an exception, and technological developments are active to reduce energy consumption and greenhouse gas emission. In particular, buildings occupy more than 20% of the total national energy consumptions. Thus, it can be said that increasing energy efficiency of the residential buildings and reducing CO2 emission are the urgent national agenda. Moreover, as ordinary people find it more and more difficult to get a lease on housing, which has become an important social issue recently, a housing production system that can actively respond to market demands is in urgent need. To build an eco-friendly system that can maximize efficiency in construction, this study attempts to examine and analyze the modular housing production system in the county and to find its problems. By suggesting the ways to improve the system, it aims to prepare for the base to revitalize the unit modular housing production system.

Due to strong wind of smartphone, change in human life is facing 21 Century's new revolution. The end of 2012, The record rate of supply of smartphone is up to 58.8 percent. So the reputation of IT power are continuing. Korea is boasting IT infrastructure, and the reputation of IT power with rapidly evolving. But Korea is one of OECD country with the longest working hours and in labor productivity, yet is located in the lower rank. Now, common social issues such as low-carbon, green growth, low birthrate, graying, labor productivity growth, the reduce greenhouse gas is constantly increasing in worldwide. So Smart Work is getting attention as a way to resolve this. In this paper, we study the impact of small business on local economy and the status information of small business on statistical point of view. And we offer the smart work countermeasures of small business through detailed action elements and the model proposed fot driving factor for the promotion of smart work. Through this, we propose the IT system model for The SMEs-type smart work system.

With the advent of smart age, the concern on smart work has gradually increased in solving our social problems including low birth, aging, low productivity and green growth with low carbon as well as encouraging the balance between work and life. Especially, the competitiveness among companies and countries to preoccupy the advanced telepresence technologies and lead the international standardization based on them have increased more than ever before. But, in our country due to the lack of core technology infrastructure and barrier to current organizational culture, R&D achievement and promotion of deployment on telepresence have not been sufficient. Therefore, It is essential to make standardization strategy and do systematic implementation for core technology which leads the telepresence market in order to fit such an environment and introduce smart work as soon as possible. Accordingly, this paper suggests the direction of standardization and implementation on telepresence for our country to lead telepresence technology and standardization through analysing the current introducing situation and technology/standardization trend.

Against the backdrop of low-carbon, green growth, many attention is focused on a sustainable society where humans and nature coexist. Carbon emissions increase with energy consumption, which is 40 percent of the world's energy consumption by buildings. Korea has a plan to make zero-energy houses mandatory only for new buildings in 2025, but it is relying on private technology investment for its technology. The reality is that the current technology costs more than 1.5 times more than general buildings, and private companies do not have many zero-energy house complexes other than experimental houses. This study aims to study the new model of zero energy house by introducing IOT system that efficiently observes and controls energy in zero energy house, monitoring pleasant environment on the web and introducing resident proper temperature maintenance system.

The 'Green Start Movement' is a practical movement of green living to efficiently reduce the greenhouse gases originating from non-industrial fields such as household, commerce, transportation, etc. for the 'materialization of a low carbon society through green growth (Low Carbon, Green Korea)'. When the new government took office, following the Lee Myeongbak Administration that had presented 'Low Carbon, Green Growth' as a national vision, it was required to set up the direction of the practical movement of green life to respond to climate change persistently and stably as well as to evaluate the performance of the green start movement over the past 5 years. A questionnaire survey was administered to a total of 265 persons including public servants, members of environmental and non-environmental NGOs, participants of the green start movement and professionals. In the results of the questionnaire survey, many opinions have indicated that the awareness of the green start movement is increasing and the green start movement has had a positive impact on individual behavior and group behavior in terms of green living. The result shows, however, that the environmental NGOs don't cooperate sufficiently to create a 'green living' effect on a national scale. Action needs to be taken on the community level in order to generate a culture of environmental responsibility. The national administration office of the Green Start Movement Network should play the leading role between the government and environmental NGOs. The Green Start National Network should have greater autonomy and governance of the network needs to be restructured in order to work effectively. Also the Green Start Movement should identify specific local characteristics to support activities that reduce greenhouse gas emissions. Best practices can be shared to reduce greenhouse gas emissions by a substantial amount.
