  • A gene encoding the major secreted fibrinolytic protein of Bacillus amyloliquefaciens CH86-1 was cloned from genomic DNAs. DNA sequencing showed that the gene, aprE86-1, could direct the synthesis of a mature protein 275 amino acids in length after processing. When aprE86-1 was introduced into B. subtilis, a mature 27-kDa protein was produced as expected. The fibrinolytic activity of the B. subtilis transformant (TF) was higher than that of B. amyloliquefaciens CH86-1, showing the possibility of increasing the fibrinolytic activity of Bacillus strains through genetic engineering.

  • The effects of oxidation on the order-disorder transition in NiPt bimetallic alloy crystal have been investigated using in-situ synchrotron x-ray scattering technique. The temperature dependence of the crystal structure and the order parameter were measured during in-situ heating and cooling under vacuum and oxygen environments. The order-disorder transition temperature of NiPt alloy crystals in vacuum was between $615^{\circ}C$ and $627^{\circ}C$. On the other hand under oxygen environment, the transition temperature decreases by about $31^{\circ}C$ after the oxidation. The change of the transition temperature can be explained by the formation of NiO crust on the surface of NiPt crystal, which alters the composition of the Ni and Pt atoms. Since the transition temperature depends sensitively on the Ni-Pt composition, the transition temperature changes as Ni atoms diffuse out to form NiO.

  • Purpose: The objective of this study was to evaluate the caries prevention effect of school-based fluoride mouth rinsing (FMR) program implemented in the Hanuul district of Mongolia, which has a very low socioeconomic status and extremely poor infrastructure for oral health. Materials and Methods: One hundred and seventy children aged from 6 to 8 years of the FMR school and 187 children aged from 6 to 8 years of the control school completed the baseline survey. Children from the FMR school rinsed with 0.05% sodium fluoride everyday under supervision, while those from the control school did not. Adjusted caries preventive fraction (CPF) for 2 years were calculated to evaluate the effect of the FMR program. Result: After 2 years, 288 schoolchildren remained in the study. Decayed, missing or filled permanent teeth (DMFT) and index of the FMR and the control schools at baseline were 0.11 and 0.12, respectively, and the average DMFT increment of the FMR and the control schools after 2 years were 0.35 and 0.65, respectively. The adjusted CPF of DMFT was 48.5%. Conclusion: These findings show that a school-based FMR is an effective caries preventive program in a socially deprived community with poor infrastructure for oral health.

  • This study was conducted to develop a forest education program through middle school curriculum linkage. We used the ADDIE model, comprising the five phases of Analysis, Design, Development, Implementation and Evaluation, to secure the objectivity of the program. In the Analysis phase, middle school textbooks were analyzed while considering middle school students' needs for curriculum linkage and the developmental stages of adolescents. The Design phase focused on promoting an understanding of curriculum subjects based on what was reviewed in the Analysis phase and concretized and organized a program that can be implemented in the forest, with a focus on science and physical education, based on the results of middle school students' needs. We also established the objectives and goals of curriculum linkage forest education, established the concept of the program, and selected the educational contents, teaching-learning methods, and evaluation methods. In the Development phase, we developed a 2-night, 3-day program linkage with the middle school curriculum and created a manual for instructors and a workbook for students. In the Implementation phase, we revised and supplemented the program through the first test operation with 24 students in their second year of middle school, after which, we carried out a six-session program for the 2-night, 3-day as the second test operation with 17 students in their second year of middle school. In the Evaluation phase, the program was evaluated by the students who participated in the second test operation using questionnaires on satisfaction and curriculum linkage understanding as well as rating scales for attitudes toward forests and environmental sensitivity. The results showed that middle school students showed positive significance in satisfaction and understanding of the middle school curriculum as well as attitudes toward forests and environmental sensitivity through the forest education program.
