최근에 한국 고유종인 미선나무 (Abeliophyllum distichum Nakai; Oleaceae) 품종 옥황1호의 유전체가 성공적으로 해독되었다. Acteoside는 다양한 활성을 가지는 물질이며, 여러개의 생화학합성과정이 제시되어왔고, 이들을 통합 검토하여 정확한 생화학합성과정을 완성하였다. 유전체 데이터로부터 2차대사산물을 예측할 수 있는 MetaPre-AI^TM와 정확한 acteoside 생화학합성과정, InfoBoss Pathway Database를 활용하여, acteoside에 관여하는 모든 효소의 유전자를 옥황1호 유전체로부터 성공적으로 확인하였다. 이는 옥황1호는 acteoside 물질을 생산할 수 있는 가능성이 있음을 의미한다. 이에 고성능액체크로마토그래피를 사용하여 옥황1호의 캘러스 세포를 분석하여 acteoside과 이의 유도체인 isoacteoside를 확인하였다. 본 연구는 MetaPre-AI^TM은 유전체로부터 2차대사산물을 성공적으로 예측하였다. 이 방법은 화학물질보다 안정적인 DNA를 분석하여 2차 대사산물을 예측하는 효율적인 방법이 될 것이다.

In this paper, a flexible track modeling of turnout was developed and dynamic characteristics of turnout rails were analyzed when a vehicle passed through the turnout. The flexible track modeling is effective to the stiffness and durability design of turnout, because it can capture the deformation and dynamic stress due to the collision of between wheels and rails when the vehicle move to the tongue rail. Also, a more accurate running safety can be obtained by considering the interaction between wheel and rail deformation. Solid finite elements were used for variable cross-sections of rails and the variation of rubber stiffness was modeled. The proposed flexible track modeling in this paper was verified to be valid by comparison with the experiment of the turnout system.

In this paper, an Adaptive Evolutionary Computation(AEC) is proposed. AEC uses a genetic algorithm(GA) and an evolution strategy (ES) in an adaptive manner is order to take merits of two different evolutionary computations: global search capability of GA and local search capability of ES. In the reproduction procedure, proportions of the population by GA and ES are adaptively modulated according to the fitness. AEC is used to design the membership functions and the scaling factors of fuzzy logic controller (FLC). To evaluate the performances of the proposed FLC, we make an experiment on FLC for the speed control of an actual DC series motor system with nonlinear characteristics. Experimental results show that the proposed controller has better performance than that of PD controller.

Our research proposes how to, systematically, count function point from initial functional requirements based on natural language. Gradually, Function Point Analysis is used to overcome the limitation of LOC(Line Of Code) for estimating software size. Moreover, it plays an important role in cost management. Function point is derived from initial requirements and is determined by experts who have an education for function point. However, currently there are few researches to cout function point by systematic or automatic rules. Through extending our porposed method, we expect that function point is able to be counted automatically or semi-automatically. This would be our future research
