Authors finished cotton-cloth with various resin at 120℃ and 150℃, and determined the formalin-content of resin and finished-cloth. The relations between formalin-content of finished-cloth and curing temperature, concentration of resin-bath, kind of resin, and formalin-content of resin were investigated. The results of studr may be summarized as follows (1) The formalin-content of finished-cloth was irrespective of the formalin-content of resin. (2) The formalin-content of finished-cloth varied with accelerator. (3) The lower the curing temperature, the higher was the formalin-content of finished-cloth. (4) The higher the concontration of resin-bath, the higher was the formatin-content of finished cloth. (5) Melamine resin left more formalne on finished-cloth than urea resin.

Radiation therapy is an effective cancer treatment modality as a primary treatment in early cancer and as an adjuvant treatment in advanced cancer, especially in head and neck lesions, but it also causes irreversible chronic damages to overlying normal tissues that may lead to wound complications. As well, at the microscopic level, radiation injury causes both stasis and occlusion of small vessels. Therefore, surgical reconstruction of previously-irradiated lesions in the head and neck poses a great problem. Fifth-six patients with head and neck lesions underwent 57 microsurgical reconstructions between 1990-1998. Thirteen patients were irradiated before surgery. The previous radiation dose was 30∼75.6 Gy. The free tissue transfer was successful in 52 of the 57 microsurgical reconstructions(91.2%). The success rate was 92.3%(12/13) in previously-irradiated patients and 90.9%(40/44) in nonirradiated patients. Postoperative complications, such as flap loss, fistula, and infection, developed in 4 irradiated patients and 8 nonirradiated patients. Overall complication rate was 30.8%(4/13) in previously-irradiated patients and 18.2%(8/44) in nonirradiated patients. Although the failure rate of previously-irradiated patients was higher than that of nonirradiated patients, there was no statistically significant difference between them. Thus, free tissue transfers in patients with previously-irradiated head and neck lesions are suitable for one-stage reconstruction.

The study was carried of out to investigate the effects of water on the fermentative characteristics of the mixed and needed dough and the quality of white pann bread produced by using of Distilled water(DW), Mineral water (MW) and Hot spring water(SW). The results of the characteristics of dough and the quality of white bread measured were as the follow. 1. Mineral water showed higher swelling in the fermentation processing but it was lower in the loaf volume at the baking stage. 2. In the quality, the loaf volume of baked bread made by using of Mineral water and Hot spring water was higher then Distilled water. 3. The measured hardness of baked bread made by using of Distilled water was lower then Mineral water and Hot spring water As the result of this quality test, the white bread made of Mineral water and Hot spring water was showed excellent result.

It has been well known that biliary cirrhosis with concomirtant impairment of renal functions were occured after prolonged obstruction of biliary tract. In the present study, an attempt was made to investigate the mechanism of impaired function and the ultrastructural change of the kidney in rats, ligated the common bile duct for 28 days days order to induce secondary biliary cirrhosis. The results obtained were as follows; 1. Secondary cirrhosis was produced evidently 28 days after ligation of common bile duct. Prominent proliferations of bile ducts and were seen in periportal area. 2. There were electron lucent materials forming lump in the subendothelium. 3. Indistinct three layers and focal widening of basement membranes were observed. 4. Focal fusions, edema and bleb formations of foot processes were seen, Electron dense materials with variable size and global shape were found in edematous foot processes. 5. Multiple myelin figures with varible size were evoked in the cytoplasm of the proximal convoluted tubule. 6. Ovoid materials with variable size were found in the mesangial matrix.

As a modern material, fibers are embedded in surrounding matrix materials and unidirectionally reinforced to form orthotropic fiber-reinforced plastic materials. Desirable material characteristics such as corrosion resistance, light weight, high specific strength and stiffness make this material an alternative construction materials. For effective use of such materials, the stability of various orthotropic structural shapes composed of thin plates need to be analyzed. Generally, the buckling behavior of thin plates with a cutout at the center has been limited to empirical studies and finite element analyses. A general formulation for the buckling behavior for this case is studied. Theoretical buckling analyses of plates with a hole at the center is investigated. The geometric complexity of the problem prohibits derivation of closed-form solutions from the equilibrium equations. Thus energy principles and the assumed displacement shapes are used to consider the effects of the cutout on buckling. On all edges, the boundary conditions are assumed to be simply supported with uniformly distributed stress. Experiments are based on rectangular box specimens. The results from finite element analyses and experiments are used to evaluate the validity of the theoretical results where theoretical results are concluded to be sound.

The average indoor concentration of the library's TSP was 0.03 ng/m³. TAB in library and lounge in college of engineering showed higher concentrations in corridors than indoors. The correlation coefficient between TAB and humidity is 0.985, so it is judged that there is a significant need for humidity control in indoor air quality management to reduce the concentration of total suspended bacteria(p<0.01).

Educational practices should be based on the sound information about the structure and function of human brain. Recently, with the result of advancement in technology, inner workings of our brain were sufficiently accumulated to actually apply to the educational practices. The eight brain-compatible elements suggested by Kovalik & Olsen(1994) were based on these knowledge about brain. This study was undertaken with the purpose of providing insights into science teaching-learning based on the brain-compatible elements derived from several brain-based learning principles. To accomplish this purpose, we explored how the elements were provided to children by teachers in science instruction. The results as follows. The levels of appreciation of the elements by teachers were high. Especially, the appreciation element of cooperation in science teaching was relatively higher than those of others. Furthermore, they had attitudes to have children relate the science subject to their real lives. For one particular element, that is, enriched environment, it was found to be relatively less appreciated, probably because of the lack of resources such as books, videos, CD, pictures, regularly scheduled guest speakers, and the others to support science contents. These findings provide a basis for understanding the roles of the brain-compatible elements in learning science. The results also highlight the need for teachers to aware of and implement the elements to create environments which encourage the maximization of the brain potentials of children when teach science subjects.
