  • Recently many countries agreed to reduce emissions of greenhouse gases into the atmosphere or at least to keep them at the current level at the Kyoto Protocol. Carbon dioxide has been proven to be 80% of greenhouse gases, contributing to the increase of the earth's surface temperature. It is reported that half of the $CO_2$ emissions are produced by industry and power plants using fossil fuels. In this article, we review and analysis domestic and abroad R & D policy trends relating to UN framework convention on climate change(UNFCCC).

  • Biofuels produced from biomass can be substituted for petroleum fuels due to GHG reduction, sustainability and environmental friendly. The process technologies that convert biomass into biofuels are varied and depend on the feedstocks. Microalgae are considered to be one of the most promising alternative source to the conventional feedstocks for biofuel. Microalgae can be converted to biodiesel, bioethanol, biogas and biojet fuel via thermolchemical and biochemical production technologies. This reviews discusses recent advance in understanding the effects of the characteristics of various processes on the production of biofuels using microalgae. The performances of microalgae based biofuel are compared.

  • Recently, with the remarkable increase in elderly persons and improvement of skin care technique, the requirements of customer for anti-aging care have become very important. Also, after cosmeceutical-product law was done in 2001, the major interesting field in cosmetic industry has been focused to developing anti-aging materials having safety and efficacy by basic science. In this review, we ill introduce the trend of anti-aging research and materials to prevent wrinkle or improve elasticity of skin.

  • Since the concept of "innovation resistance" was introduced as a summary construct for customers not adopting a superior innovation, a lot of researchers have examined to identify the relationship between the innovation resistance and the various innovation and situation variables. This paper addresses the innovation resistance coming from the introduction of a new R&D grant management system(RGMS) in a university. The new RGMS is based on research grant management policies newly accredited by the government, where the central management of the research grants is indispensable. We have surveyed professors and researchers about the introduction of a new RGMS, and empirically analyzed the perceived innovation characteristics and the user characteristics affecting the innovation resistance. The result shows that perceived risk is the most important factor influencing on the innovation resistance.

  • With the advent of new frontiers in robotics, the spectrum of robot research area has widened in many fields and applications. Other than conventional robot research, many technologies such as smart devices, drones, healthcare robots, and soft robots are emerging as promising applications. Due to the research complexity of this topic, this research requires international collaboration and should be fertilized by R&D policies. This paper aims to propose a method to perform a cross-national analysis of robot research with unstructured data such as papers in the proceedings of an international conference. Text analytics are applied to extract research issues and applications in an automatic manner.

  • High Speed permanent magnet machines are currently being developed for a number of applications including gas turbine power plants, air conditioning systems, machine tools, gas pumps, high performance vacuum pumps, flywheel energy storage systems, aircraft fuel pumps, and so on. Using a high-speed machine eliminates the necessity of the mechanical gearbox and could certainly increase the system efficiency and reduce the total cost. In addition, a high-speed machine has the advantage of small dimension and low weight, i.e. low weight to power and volume to power ratio. This paper presents a review of some important applications (mostly still under development) where high-speed machines arc used, highlighting the advantages of the technology in each case.

  • Seaweeds contain various bioactive compounds. Especially, brown algae (Phaeophyceae), the second abundant group of seaweeds, contain numerous nutraceutical and pharmaceutical substances. In this review, we investigated on the brown algae-related patents and literature. Consequently, the research and development (R&D) trends of patent related to brown algae showed that the large majority was applied as the composition of stem cell culture medium and mostly used as active substances. In conclusion, we suggested that many researchers try to investigate and develop applications of brown algae as the sophisticated-level biomedical materials because brown algae are actively developing as simple-level biomedical materials.

  • The Chinese government has been promoting core industries in accordance with the 'Made in China 2025'. As a result of injecting huge subsidies to develop core industries, a great success has been achieved in the electric vehicle and battery industry, however, the semiconductor industry has almost no performance. This study aims to examine whether the subsidy policy of a developing country helps their own domestic firm to overcome the first mover advantage of an advanced country's firm. From the game theoretical analysis, the results have shown that the subsidy policy of the developing country's government creates the profits shifting effect which arises from the developed country's firm to the developing country's firm. When there exists R&D efficiency gap between the two firms, however, most of these profit shifting effects are offset, which implies that the subsidy policy of developing countries is likely to fail.
