  • On the basis of total page, the coverage rate of education of safety and health in textbooks of elementary school was approximately 10%. In middle school, the contents of safety education were addressed mainly in subject of chemistry below about 5% of coverage rate whereas the contents of health education appeared mainly in subject of athletics below about 15% of coverage rate. Similarly, the contents of safety education and health education in textbooks of high school were indicated mainly in the subjects of chemistry and athletics, showing below about 5% and 30% of coverage rate, respectively. In conclusion, the education level of safety and health in textbooks was generally lower compared to other contents. The coverage rate of safety education was relatively lower than health education, which implicates that extensive contents related to safety education are needed to be added to textbooks in order to establish preliminary attitude for preventing workplace accident.

  • Glucosamine (GlcN) is widely used in the nutraceutical and pharmaceutical industries. Currently, GlcN is mainly produced by traditional multistep chemical synthesis and acid hydrolysis, which can cause severe environmental pollution, require a long prodution period but a lower yield. The aim of this work was to develop a whole-cell biocatalytic process for the environment-friendly synthesis of glucosamine (GlcN) from N-acetylglucosamine (GlcNAc). We constructed a recombinant Escherichia coli and Bacillus subtilis strains as efficient whole-cell biocatalysts via expression of diacetylchitobiose deacetylase ($Dac_{ph}$) from Pyrococcus furiosus. Although both strains were biocatalytically active, the performance of B. subtilis was better. To enhance GlcN production, optimal reaction conditions were found: B. subtilis whole-cell biocatalyst 18.6 g/l, temperature $40^{\circ}C$, pH 7.5, GlcNAc concentration 50 g/l and reaction time 3 h. Under the above conditions, the maximal titer of GlcN was 35.3 g/l, the molar conversion ratio was 86.8% in 3-L bioreactor. This paper shows an efficient biotransformation process for the biotechnological production of GlcN in B. subtilis that is more environmentally friendly than the traditional multistep chemical synthesis approach. The biocatalytic process described here has the advantage of less environmental pollution and thus has great potential for large-scale production of GlcN in an environment-friendly manner.

  • Environmental problems became bigger and widely known among all parts of the society in the last decade. The broad and sustainable study of the environment is the most basic and primary solution to the problems. For this reason, International Environmental Project Olympiad (INEPO) was organized in 1993. Many countries have participated in this organization. Therefore, the purpose of this study was to revitalize the environmental education and to realize the value of environmental education by making students aware of the environmental problems through the INEPO and Korean Environmental Olympiad (KEO). To achieve these goals, we conducted as follows First, we introduced aims, major contents and rules of the INEPO and grasped problems related to the applying method of students who want to participate in the INEPO in Korea. In addition, we introduced both results of domestic contest for participating in the 14th INEPO and of the 14th INEPO itself opened in 2006. Second, we analysed participants' themes according to project types such as environment-biology, environment-chemistry, environment-physics, environment-health and environment-social sciences from Previous INEPOs. Third, we had interviews with several participants to gather their thoughts on motivation and impression of participation, the reason of theme selection, and the method of environmental education in school, by visiting each booth of INEPO. Finally, we suggested sustainable methods of the KEO to revitalize environmental education, and proposed various methods to revitalize the environmental education through the KEO and INEPO in the primary and secondary schools.

  • To meet the objectives of environmental education, teachers especially have to perceive the importance of environmental education, comprehend various characteristics of teaching/learning methods, and be able to conduct classes by choosing proper teaching/leaming methods in accordance with a specific purpose and educational focus about environmental education. Therefore, it Bs necessary to investigate the current status of Korean environmental education and provide teachers with appropriate environmental teaching/leaming methods. To this end this study aims to examine Korean science teachers'perceptions'on environmental education and the kind of teaching/learning methods which can be utilized in environmental education. Teachers who completed the survey were 135 science teachers from middle and high schools in Seoul, and 126 social science teachers from Kyoungki province. The majors of the science teachers were in physics, chemistry, biology, geology, and earth science. Also, there was one teacher who majored in special education. For social science teachers two majors were common, geography and general sociology. After analysis of the data from the surveys the results are as follows. First, science and social science teachers in middle and high school recognized the necessity of environmental education in school education. Second, most teachers had applied environment related topics to their subject of study occasionally, but they mostly concurred that environment related contents should be included in their textbooks. Third, science teachers agreed that field trip, discussion, and the STS approach were the most proper methods for environmental education, and social science teachers agreed that field trips, inquiry, and discussion were the most appropriate methods for a teaching environment. They realized that they should decide good teaching-learning methods appropriate to the objectives and content needed for effective environmental education as they selected different teaching-learning methods according to detailed environmental objectives and contents in their textbooks.
