The u-City construction project has become a hot topic in the construction market because it seems economic value-added field for construction firms. However, construction firms don't willingly participate in the u-City construction market because environments of the future business for the u-City are very uncertain. Scenario planning is a very powerful method in managing this uncertain planning situation and is based on scenarios that help each enterprise appropriately adapt itself to its own business environments. Therefore it is based on the main principles of systems thinking and multiple futures. For the purpose of dealing with such uncertainties, this paper attempts to develop the possible market scenarios of the u-City construction market in S.Korea through a scenario planning approach. From this perspective, we considered various aspects of the u-City construction such as market demands, technology development, policy level and management environment. After considering the relevant issues, we identified the main trends and key uncertainties. Finally, we developed three coherent u-City construction market scenarios. Construction firms can use these scenarios as a basic reference for market analysis and business strategy. Therefore, this paper is able to enhance the participation of construction firms in the u-City construction market.

The world has faced with various environmental problems such as climatic change, global pollution, and depletion of natural resources. Conventional economic development continues not only to intensify the magnitude of the problems but also to damage growth potential of future generations. Therefore, recent manufacturers are highly required to accommodate themselves to sustainable development that aims at preventing the loss to the future generations. Moreover, the manufacturers are under heavy pressure from various environmental regulations. This paper proposes green bill of material (Green-BOM) which conforms to the environmental regulations to restructure eco-friendly manufacturing system. Green-BOM is useful for managing green product and process information to satisfy several environmental regulations by recording energy consumption, recycle rate, volatile organic compounds (VOCs), substance information, and so on.

Limited quantity and non-uniform distribution of fossil fuel over the world, along with the environmental concerns of increasing $CO_2$ emissions, indicate that gradual and planned switchover to the sustainable energy sources is the need of the day. Ocean energy is well-distributed over the coasts, abundant, renewable and available in the form of wave energy, tidal energy and thermal energy. India has gathered precious experience from the pilot plants utilizing these methods over the last few years. One of the main constraints is deemed to be the grid connectivity. Time has come to transform this limitation into opportunity. Ocean power can be a very suitable option for the coastal belts and the islands. Implementation of this concept would require large-scale industry participation along with favourable government policies in the coming years. This article attempts a review of the ocean energy initiatives in India and proposes a roadmap for the future.

Bio-venture companies have undertaken harsh environment after 2000 bubble corruption. It is unlike to be changed in the near future. The business model of near-term cash flow, financial stability and survival is a key issue to be discussed. The company shall be rearranged to achieve fast recovery from investment and have to show clear and quantitative business model to the investors. Nevertheless, bio-venture should not drop long-term value creation by sacrificing the possibility of emerging technologies. Prior to clarifing agro-bioventure business model, GMO strategy should have broad supports from stakeholders. The interests and worries of stakeholders are discussed and SWOT is analyzed. For sustainable economy of future, new technology continuously should be invested to fit ROI model of genomics-based GMO developments. Hybrid of products ${\varepsilon}$ technologies may be one of the favorites in this stormy season.

Informationization is fast progressing in Korean and the informationization of education is also moving ahead fast. With informationization of education going fast ahead, cyber education is also increasing. Given such scenario, we should establish countermeasures not only to accommodate the current curriculum but also to accommodate the surplus school facilities created by cyber education by compartmentalizing the classrooms for future life-long education, lease and sale in lots. In conclusion, the school construction plan should be established to systematically cope with the future changes systematically.

Purpose - This study aimed to explore and examine the government policies and supporting systems of the traditional market in Korea. Research design / data / methodology - Recognizing these problems, the Korean government enacted three special legislations and adopted six support policies in support of the traditional markets. Results - Those markets with modernized stores, parking lots, and arcades have certainly increased sales and the number of customers. However, this uniform modernization support policy was short of supporting strategies that could have developed characteristics and advantages of each market, so many markets and merchants lost self-sustainable ability and ended up with relying on government support. Conclusions - The study indicates that Small & Medium Business Administration's role in implementing government policies including selection of the markets that needed to be modernized, developing commercial areas in connection with traditional market and neighboring shopping streets, customizing and improving distribution system, developing specialty stores, merchant college, merchants' self-sustainable ability, and creating convenient and safe shopping environment is vital to traditional markets' future success.

Fast depletion of fossil fuels is urgently demanding a carry out work for research to find out the viable alternative fuels for meeting sustainable energy demand with minimum environmental impact. In the future, our energy systems will need to be renewable and sustainable, efficient and cost-effective, convenient and safe. Hydrogen is expected to be one of the most important fuels in the near future to meet the stringent emission norms. The use of the hydrogen as fuel in the internal combustion engine represents an alternative use to replace the hydrocarbons fuels, which produce polluting gases such as carbon monoxide (CO), hydro carbon (HC) during combustion. In this paper contemporary research on the hydrogen-fuelled internal combustion engine can be given. First hydrogen-engine fundamentals were described by examining the engine-specific properties of hydrogen and then existing literature were surveyed.

Owning to rapid infrastructure development, Asia is experiencing dramatic economic growth. There are not a few cases in which, however, economic growth is achieved by increasing the external diseconomy. Pursuit of sustainable development is one of the most important issues for mankind. Under the post-industrial capitalism society, however, there seems a big risk of increase in the external diseconomy worldwide. The objectives of this manuscript are to discuss importance of risk management of construction practice in present and future. Regarding the latter, a particular attempt is made to discuss how project risk communication should be done to reduce the external diseconomy. Presently, one of the important issues in implementation of infrastructure projects is practice of risk management to properly manage time, cost, quality, and safety: mainly maximization of internal economy. Multi-party risk and uncertainty management process (MRUMP) is one of tolls to assist it. The idea on MRUMP can be used to reduce the external diseconomy through identifying, sharing, and tuning people's rhythms.

This study presents the ultrasonic cavitation bubble- and gas bubble-assisted fractional precipitation that dramatically improves the precipitation efficiency in existing precipitation method for purifying (+)-dihydromyricetin. Compared to the conventional method, the time required for precipitation was reduced by 40 times. The particle size was reduced by 4.0-7.4 times and 3.7-4.4 times for cavitation bubbles and gas bubbles, respectively, and the diffusion coefficient was increased by 5.1-9.2 times (cavitation bubble) and 3.7-4.4 times (gas bubble). Meanwhile, the precipitation rate constant was increased by 11.0-65.0 times and 17.0-24.6 times and the activation energy was decreased by -5,543~-9,655 J/mol and -6,546~-7,404 J/mol, which resulted in an improved precipitation rate. The results of the thermodynamic analysis showed that the precipitation was exothermic and non-spontaneous.
