According to the result of study, landscape tree indicated high carbon dioxide storage effect compare to bush, in which broadleaf tree indicated higher storage function than coniferous tree. It is believed to be the storage of carbon dioxide can be increased by increasing the composition rate of forest plants in the urban park. According to the direct estimation result of carbon dioxide storage in terms of example area, storage of carbon dioxide is estimated to be "seoul a zone" 476,818.8 kg‧CO2/㎡‧yr, "anyang b zone" 186,435.7 kg‧CO2/㎡‧yr, "daejeon c zone" 262,826 kg‧CO2/㎡‧yr, "kwangju d zone" 231,657.8 kg‧CO2/㎡‧yr. The carbon dioxide storage per unit area estimated to be "seoul a zone" 3.4 kg‧CO2/㎡‧yr, "anyang b zone" 5.0 kg‧CO2/㎡‧yr, "daejeon c zone" 2.6 kg‧CO2/㎡‧yr, "kwangju d zone" 5.6 kg‧CO2/㎡‧yr. The result of indirect carbon dioxide reduction effect estimated to be "seoul a zone" 291,603.4 kg‧CO2/㎡‧yr, "anyang b zone" 165,462.4 kg‧CO2/㎡‧yr, "daejeon c zone" 141,719.2 kg‧CO2/㎡‧yr, "kwangju d zone" 154,803.4 kg‧CO2/㎡‧yr. Carbon dioxide reduction potential amount through the urban park was increased to 1.6 times to 1.8 times when calculated to the indirect effect.

Melittin significantly increased the intracellular Ca(2+) mobilization via receptor-operated calcium channel but not the intracellular Ca(2+) release. It caused AA release via activation of Ca(2+)-dependent phospholipase A2 (PLA2) and catecholamine secretion in a dose-dependent manner. Acteoside dose-dependently inhibited the release of AA and intracellular Ca(2+) mobilization induced by melittin. Acteoside reduced the catecholamine release and raised the amount of intracellular chromogranin A which is co-released with catecholamine from melittin-stimulated PC12 cells. Taken together, our results suggest that acteoside could suppress the exocytosis via inhibition of Ca(2+)-dependent PLA2 and extracellular Ca(2+) influx in PC12 cells stimulated by melittin.

In addition, a total ultrasonic investigation system was designed by adopting a Fabry-Perot interferometer, which receives ultrasonic signals without any contact. For non-destructive test SM45C, which contains some flaws was used as a test material. Because it is easy to align light beam in receiver, and the length of the light beam does not change much even if convex mirror leans towards one side, confocal Fabry-Perot interferometer, which has stable frequency, and PI control are used to correct interfered and unstable signals from temperature, fluctuation and time shift of laser frequency. Stable signals are always obtained by the feedback of PI circuit signals in the confocal Fabry-Perot interferometer. The type, size and position of flaws inside the test material were examined by achieving the stabilization of an interferometer. This study presented a useful method, which could quantitatively investigate the fault of objects by using a Fabry-Perot interferometer.

A reversible change in the SERS intensity with the temperature has been observed, with the intensity at 15 K being larger than that at 300 K by a factor of ∼3. Various factors that can affect the SERS intensity such as the laser-induced change in surface morphology, adsorption and desorption, and destruction of adatoms could be eliminated as a possible cause for the observed temperature dependence. Enhancement of the Raman intensity has been calculated over the experimental temperature range based on the electromagnetic (EM) model for SERS proposed by Gersten and Nitzan. It has been found that the observed temperature dependence can be explained qualitatively with the EM model calculation.

With hematoxylin and eosin stain, an epidermal defect, abnormally located fat cell lobules, and absence of the upper and midportions of the dermis were observed, conforming to a typical histopathologic picture of focal dermal hypoplasia. Electron microscopic examination of the atrophic site showed loose collagen bundles, collagen fibers with loss of regular bands, abnormal fibroblasts, and disruption of the basement membrane zone. These defects in the basement membrane zone strongly suggest that abnormal formation of type IV collagen is associated with focal dermal hypoplasia, and that this abnormal formation of collagen is correlated with the clinical sign of skin atrophy.
