  • The effects of diterpene acids (i. e. pimaradienoic acid, kaurenoic acid, hydroxy cembratrienoic acid and dihydroxycembratetraenoic acid) on malondialdehyde generation by rat platelets in response to thrombin were studied. All the compounds inhibited the generation of MDA.

  • In this paper, we propose a novel framework for technology policy aimed both for the generation and diffusion of new technologies. Based upon critical examination of related theories and practice of technology policy, we identify two major problems in current technology generation policy, and the segregated approach to technology diffusion policy from technology generation policy. To remedy these problems, we argue that two goals of technology policy of generation and diffusion should be integrated and synchronized via unified policy framework, and propose the conceptual configuration for policy implementation which can serve the desired objective.

  • The generation cost of photo voltaic is the most expensive among the renewable energy. To reduce the generation cost of photo voltaic, the proposed method added the regeneration power of elevator. Therefore we have the simulation results the proposed method is 60[%] higher than the previous photo voltaic generation for efficiency of generation.

  • With regard to price elasticity and cross elasticity of electricity, optimal generation expansion planning method including load management effect is suggested. In addition, optimal peak time price can be determined simultaneously, and we adopt peak time tariff as load management strategy. Instead of using hourly marginal demand curves where we can get customer surplus, we used chronological load curve with constraints to preserve social welfare. This method is proved useful in short-term generation expansion planning.

  • This paper proposes a new test generation method. Most of the test generation methods are gate-level based, but our scheme is VHDL based, especially in other word, behavioral-level based. Our test pattern generation method uses software test method. And we generate deterministic test pattern with this method. The purpose of our method is to reduce the time and effort to generate the test patterns for the end-product test of IC.

  • Fault dropping is a very important part of test generation process. It is used to reduce test generation time. Test generation systems use fault simulation for the purpose of fault dropping by identifying detectable faults with generated test patterns. Two kinds of delay fault model is used in practice, path delay fault model and gate delay fault model. In this paper we propose an efficient method for gate delay test generation which shares second test vector.

  • It is one of the important problems how to maintain the optimal electric power generation mix. The Objective of this study is development of a computer model which can be used to forecast the investment of power generation unit by the plant owners after restructuring the electricity industry. The impacts of the various government policies can be analyzed using the computer model, thus the government can formulate effective policies for achieving the desired electric power generation mix.
