Vibration measurements using image processing have been studied by many researchers as it can remotely measure vibration displacements at multiple points simultaneously. It is difficult, however, to obtain accurate displacement from the measured image signals because the resolution of image data is dependent on camera performance and normally lower than that of vibration transducer directly measured. This paper suggests the enhanced technique for vibration displacement measurement by applying the expected value of edge probability distribution to the varying pixel points in the image. The method can both increase the resolution limit of camera image and decrease the measurement errors. The working performance of the proposed technique is verified applying to the vibration measurement of a rotating machine.

In this study we examined whether vitrified Hanwoo (Korean cattle) IVM/IVF/IVC blastocysts can survive in vitro/in vivo by a quick one-step dilution method and these embryos result in live births. Blastocysts produced in vitro were vitrified by serial exposure to glycerol (G) and/or ethylene glycol (EG) mixtures of 10% (v/v) G for 5 min, 10% G plus 20% EG (v/v) for 5 min, and 25% G plus 25% EG (v/v) for 30 see.

Vibration measurement of rotating shafts by installing sensors such as accelerometers or displacement sensors is costly and dangerous in some cases. As an alternative method, vibration measurement using camera images has been researched because sensor installation is not needed and displacement of a rotating shaft can be directly evaluated. This paper also suggests the enhanced technique applicable to the measurement of vibration of a large-scale rotating shaft. The concurrent methods based on camera images use marks, which are hardly applicable to rotating shafts. The proposed method measures vibration without any marks by evaluating shape errors. The working principle of the method is described and verified by a series of experiments.

I studied on the dual principle the negative-positive toward 'the motion of Taijiquan'. The results are as follows. The grade of comprehension on the dual principle for the negative-positive for human-body is equal to the comprehension on Taijiquan. YeoBiSae is judged abstractly for the image of MuGeug and GiSae for the image of TaeGeug on the motion of Taijiquan progressing program. The motion of Taijiquan is divided up the extension and contraction. In the motion of Taijiquan, the extension exercises make use of positive energy and DogMaeg(독맥), the contraction exercises make use of negative energy and ImMaeg(임맥).

This paper deals with effect of wind forces and moment acting on the training ship SAE NUR/. The results of drift angle and counter rudder angle due to wind effect are calculated by using the static equilibrium method especially with nonlinear mathematical expression, and then the critical wind velocity is found out. The given results am be applied directly to T/S SAE NURI in handling under the wind condition and used for merchant ships as a referential tool.

In this paper, the structural and thermal integrity of a Dual Mass Flywheel (DMFW) being developed by HMC is assessed with conventional FEM code. Some parts were modified in order to satisfy the SAE and RICARDO's assessment limit, and we found that FEM was valuable tools in developing new DMFW system.
