The mechanism design is synthesis of suitable mechanism which can be output motions about input motions. That has generally two steps which are the type synthesis and the dimensional synthesis. And required mechanism analysis step for confirming middle or final result. The type synthesis is definition of mechanism type which required aim and the dimensional synthesis is calculation of dimension about defined type mechanism. The type synthesis of mechanism is included qualitative design field which isn't defined systematic design method. especially, the most difficult step for mechanism design automation. In this paper proposed the component modular design method which is figured mechanism types automate with component modules using component modular approach. And develop CAD(Computer Aided Program) program for application.

Escherichia coli RNase P is a ribonucleoprotein composed of M1 RNA and C5 protein. Previously, analysis of RNA aptamers selected for C5 protein from a synthetic RNA library showed that C5 protein could bind various RNA molecules as an RNA binding protein. In this study, we searched cellular RNA motifs that could be recognized by C5 protein by a genomic SELEX approach. We found various C5 protein-binding RNA motifs derived from E. coli genomic sequences. Our results suggest that C5 protein interacts with various cellular RNA species in addition to M1 RNA.

This paper describes the conceptual design of new robot hand by type synthesis. The conventional robot hands with rotational movement have bad controllability because the distance between the final rotational joint and the center of things grasped is changed according to the size of things grasped. This paper uses the systematic procedure of type synthesis and the knowledge for designing robot hands. The new 6-bar Watt I type conceptual robot hand with rectilinear translational movement is proposed.

Statistical design of experiments was used to optimize the MOF-5 synthesis process. A mixture design was employed to optimize precursor concentration. The optimal composition of three chemical materials, terephthalic acid, zinc acetate dihydrate, and N,N-dimethylformamide for MOF-5 synthesis was determined by extreme vertices design methods as follows; 1 mol : 2.7 mol : 40 mol. A multilevel factorial design was selected to screen the significance of synthesis reaction conditions such as temperature, time, and stirring speed. Statistical analysis results suggested excluding stirring speed from further investigation. Using a central composition design, the synthesis time and temperature were optimized. The quadratic model equation was derived from 13 synthesis experiments. The model predicted that MOF-5 synthesized at 119 ℃ for 10.4 h had the highest crystallinity.

Although asynchronous designs have become a promising way to develop complex modern digital systems, there is a few complete design framework for VLSI designers who wish to use automatic CAD tools. Especially, high-level synthesis is not widely concerned until now. In this paper we Proposed a method for high-level synthesis of asynchronous systems as a part of an asynchronous design framework. Our method performs scheduling, allocation, and binding, which are three subtasks of high-level synthesis, in simultaneous using a transformational approach. To deal with complexity of high-level synthesis we use neighborhood search algorithm such as Tabu search.
