The effects of the moisture and thermal annealing on CLBO crystal have been investigated. CLBO has hydrated at high humidity condition, resulting in 5B$_2$O$_3$$.$Cs$_2$O$.$8H$_2$O. The surface hydration seems to induce the cracking and the refractive index change in CLBO. The thermal annealing is effective to restore the changed index.

Alveolar ridge augmentation and preservation techniques designed to reconstruct deformed alveolar ridge now occupy a major role in esthetic dentistry. Previously, deformed alveolar ridges were filled with plastic materials(porcelain or resin) of prosthesis to restore ridge contours, which resulted in larger teeth and food impaction under the pontic base. So, prostheses of this type were unacceptable and really detectable when patients smiled. But nowadays, alveolar ridge augmentation procedures enable the dentists to provide patients with fixed prostheses that are esthetic. The development of guided tissue regeneration technique and materials also have made a major impact on extending the scope of therapeutic horizons in dentistry.

In this paper we propose a novel way to restore degraded image using wavelet transform & filterbank. First, we devide a degraded image into 4-suband images using UDWT(Undecimated Wavelet Transform), and then use a proper CLS (Constrained Least Square) filter in each subband. Using a proper CLS filter ineach subband, we can save high grequency components of original image. We reconstruct a restored image from the downsampled subband images using wavelet tansform. Even though there is a trade-off between ISNR and calculation loads, we reduce the calculation loads by using wavelet transform in reconstruction with a negligible degradatiion in ISNR.

The environmental damage caused by river-improvement and slope of incision cliff can dest habitations of animate nature and it takes long time for restoration. River system constructed with stability of flood control, fine biotope, harmony with surroundings should be need to protect and restore nature. Therefore, in this study, conduct comparative experiment in various methods which are stable hydraulically and develop vegetation on revetment of bank, stream bed protection and disaster prevention aspect.

We propose a novel noise littering method based on adaptive windowing. To restore a noisy signal adaptive filtering methods have been widely researched and used. However, conventional adaptive filtering methods have a trade-off between noise suppression and edge preservation since they adopt fixed size filters. In this paper applying the adaptive windowing concept to adaptive filtering, we overcome the trade-off, The filter size is adaptively selected depending on signal statistics. The visual results of the signal and image restorations convincingly show the superior preservation of edge and detail and suppression of noise for the proposed adaptive windowed adaptive filter compared with conventional methods.

A technique for insertion of a long silicone T-tube in patient with critical stenosis and high-risk resection and primary anastomosis of long segment of the distal trachea is presented. It was not easy to insert a long T-tube by existing methods because of flexibility of a T-tube and tightness of stenosis. So we used a silastic endotracheal tube and guiding wire as stylet of a T-tube. During insertion, ventilation was normally maintained through the lumen of endotracheal tube. This provided rapid relief from airway obstruction and asphyxation and is a easy, safe and effective method to restore patency of the major airways.

The oral administration of deer horn extract was proved to cause a considerable amelioration to the impairment of hepatic oxidative phosphorylation and to the decrease of ATP content in liver tissue induced by cholesterol ingestion. Deer horn extract was shown to accelerate considerably incorporation of acetate-1-C$^{14}$ into cholesterol in liver tissue and it tends to restore a decrease of GOT activity of liver tissue, caused by cholesterol administration. Histological examination showed that deer horn extract had a remarkable preventive effect against fatty infiltration of organs such as liver, heart, spleen, and adrenal gland of cholesterol given rabbits.

In order to derive homogeneous remould soil sample, which is very important for obtaining reliable experimental results in terra-mechanics research, the characteristics of two clay soils at high moisture contents after remoulding treatment were investigated . It was found that with the remoulding process employed the coefficients of variation was less than 1.2% for the soil density and the soil could be treated as fully saturated soil. Therefore, the remoulded and will restore after a period of time. Some suggestiions were given follow the results of the drop cone test.

An exploration for an emotional intelligence paradigm has been delineated. Emotional intelligence is investigated in terms of composing machine as a modern abstract art. The system consists of interface, plan and performance modules. Design concepts of the system are modular, open, and user friendly to ensure the overall performance. The exploration of art in the view of intelligence, information and structure will restore the balanced sense of the art and the science seek the happiness of life. The investigations of emotional intelligence will establish the foundations of intelligence, information and control technologies.
