The result of comparison and analysis study of institutionalization and exchange status of environmental education in South Korea, the People's Republic of China, and Japan, Northeast Asian countries that are closely related to Korea, is summarized as the following: First, this study shows that the process of environmental education institutionalization requires an instigation. For example, a specific environmental policy is established after raising awareness to modify environmental policies, as the result of aggravation of damage due to pollution. Therefor, it is the necessary process for the establishment of an environmental policy in order to proceed environmental education institutionalization. Second, even though institutionalization processes of environmental education for the three countries are considered to be very similar, differences are apparent if one carefully examines the content of environmental education for each country. In particular, South Korea, the People's Republic of China, and Japan all agree that environmental education is necessary, but differ in their ideas of main body for advocating institutionalization, as well as maintenance level of environmental education. Third, the order of establishment of environmental education institutionalization is Japan, South Korea and China and there exists about a 10 years time gap between each country. Fourth, the environmental education exchange was formed between South Korea and the People's Republic of China and between South Korea and Japan, first. Then it was enlarged to TEMM(Tripartite Environment Ministers Meeting) and TEEN(Tripartite Environmental Education Network) among three countries.

The aim of this research was to evaluate the performance of insoluble electrode for the purpose of degradation of Rhodamine B (RhB) and oxidants generation [N,N-Dimethyl-4-nitrosoaniline (RNO, indicator of OH radical), O3, H2O2, free Cl, ClO2)]. Methods: Four kinds of electrodes were used for comparison: DSA (dimensional stable anode; Pt and JP202 electrode), Pb and boron doping diamond (BDD) electrode. The effect of applied current (0.5～2.5 A), electrolyte type (NaCl, KCl and Na2SO4) and electrolyte concentration (0.5～3.5 g/L) on the RNO degradation were evaluated. Experimental results showed that the order of RhB removal efficiency lie in: JP202 > Pb > BDD ≒> Pt. However, when concerned the electric power on maintaining current of 1 A during electrolysis reaction, the order of RhB removal efficiency was changed: JP202 > Pt ≒ Pb > BDD. The total generated oxidants (H2O2, O3, free Cl, ClO2) concentration of 4 electrodes was Pt (6.04 mg/W) > JP202 (4.81 mg/W) > Pb (3.61 mg/W) > BDD (1.54 mg/W), respectively. JP202 electrode was the best electrode among 4 electrodes from the point of view of performance and energy consumption. Regardless of the type of electrode, RNO removal of NaCl and KCl (chlorine type electrolyte) were higher than that of the Na2SO4 (sulfuric type electrolyte) RNO removal. Except BDD electrode, RhB degradation and creation tendency of oxidants such as H2O2, O3, free Cl and ClO2, found that do not match. RNO degradation tendency were considered a simple way to decide the method which is simple it will be able to determinate the electrode where the organic matter decomposition performance is superior. As the added NaCl concentration was increases, the of hydrogen peroxide and ozone concentration increases, and this was thought to increase the quantity of OH radical.

A aqueous solution of malodorants (i.e., n-valeraldehyde, n-valeric- acid, 2-methylisoborneol, and trimethylamine) was exposed to 200kHz ultrasound with a power of 6.0W/cm2 per unit volume in a sonochemical reactor under room temperature and atmospheric pressure condition. The concentration of malodorants decreased with irradiation time, indicating pseudo-first-order kinetics. The removal efficiency of malodorants was about from 50% to 96% decomposed after 90 minutes sonication. At the deodorization, it was determined by triangle odor bag(TOB) method for odor sensory measurement, and it indicated that over 60% of relative odors were deodorized with degradation by the sonication.
