It is said that ceramic arts which reflects the sprit of the age and culture is one of the representative cultural assets in Korea. Ceramic arts has the longest tradition and it has been used in our everyday life from a historical perspective. Unfortunately, most textbooks we use nowadays just show some art works for appreciation. It is impossible to teach unique techniques of ceramic arts with those textbooks. Traditional culture is not considered as a main part of educational contents but surrounding elements. Therefore it is hard for students to learn about our traditional culture deeply and it is also difficult to know the importance of the ceramic arts in secondary schools. Through the education of ceramic arts students can understand our traditional culture and they can also experience the formative arts by using plane and dimensional techniques. Teachers have to focus on historical background, types, functions, and sense of beauty of ceramic arts when they teach students in school. Students can use the knowledge in their daily lives. The education of ceramic arts encourage students to create new culture for ceramic arts.

Culture of Latin cultura culture derived from a translation of the original meaning of words was farming and cultivation, culture, art and later became the will of. British anthropologist E. B. Tyler book "primitive cultures, Primitive Culture" (1871) Culture in the "knowledge. Beliefs Arts. Morality. Law. Practices, including as a member of human society acquired the totality of skills or habits," he gave the definition. Culture can be seen in the human reason, of the form of action, not genetic thing by playing by learning to learn from the community and received the whole thing says. Thus, the prevalence of active cultural power of vigorous training is possible can. In this sense, our ceramic culture also reaffirming the importance of education and the reorganization is needed. Culture and what it takes to become a force larger than the act of teaching. Who supply the consumer with the culture and the sharing of feelings that can be read properly considering the skater to the consumer unless the formation of culture is impossible. In this regard, this study realized the importance of education and culture, as the current situation in our country and the activation of ceramic craft education is to provide.

Because it is impossible to form a culture. To correctly read the code unless the consumer is considering skater that can be shared in the emotion of the characters and the consumer culture that supply. May be possible to force the active dissemination of education shall ceramic crafts culture. We need the ceramics craft culture in this sense also once again confirmed the importance of education and redevelopment. The workshop enabled to the Ceramic Study presented based on the importance of education in workshop operations Activation is required in order to plan the education and above all a culture of catheter positioned in the area of contemporary craft. Such as teaching methods and ways to activate.

The microbial adsorption characteristics of two different media for biological treatment were studied using attached diverse microbes onto activated carbon and ceramic. The results in the experiments of the characteristics of physical adhesion on two different media with addition of high and low concentrated substrate in the culture were observed that the efficient of adhesion onto F-400 activated carbon was higher over that of ceramic due to the surface area of media. The irradiation treatment by ultrasonication with 400 W power and 3 min retention time on the media without addition substrate conditions and subsequent mixing throughly the culture showed the highest efficiency of cell detachment on the media. Three different microbes, P. ovalis, A calcoaceticus, and B. subtillis were used for the study of the characteristics of microbial adhesion on the media. p ovalis showed the highest adhesion capability while B. subtillis showed the lowest capability adhesion onto media either addition of substrate in the culture. The mixed bacterial culture showed $10\%$ lower removal efficiency of DOC in the low concentrated substrate culture compared to the single pure culture. Whileas, it did not show significant difference between two cultures at high concentrated substrate. It was also observed same population density of microorganism by counting of microbes adhered to microbial media with an ultrasound treatment.

The addition of the ceramic powder as state of bare in culture medium has stimulated the growth of Achyranthes japonica in both the disorganized cell and the plantlet. The grwoth rate of Hyoscyamus niger adventitious root and Pylatycodon grandiflorum hairy root was enhanced up to 100 and 250%, respectively, even though Scopolia parviflora hairy root and Hyoscyamus albus adventitious root were not. The ceramic powder has enhanced the growth of H. niger adventitious root even in a test tube immersed into its culture medium to irradiate alone without any direct contact. The ceramic powder seems to have a significant role on both the growth and the physiological action of some plants.

We have investigated that a couple of soft ferrite ceramic powders having a spinal structure have shown the effect on growth and secondary metabolites production of some medicinal plants cultured in vitro. The addition of the ceramic powders as bare state to culture medium has stimulated the growth of Achyranthes japonica callus and plantlet, adventitious root of Hyoscyamus niger and Platycodon grandiflorum hairy root about 65, 75, 150 and 50%, respectively. Whereas Centella asiatica callus and plantlet, Scopolia parviflora hairy root, and Hyoscyamus albus adventitious root were not affected markedly. Moreover, the ceramic powder has enhanced the growth of H. niger adventitious roots even under conditions of irradiating alone without any direct contact between ceramic powder and media. Based on growth stimulation effect, the ceramic powders have enhanced the gross production of tropane alkaloid in H. niger adventitious root, and polyacetylene in P. grandiflorum hairy root about 35 and 30%, respectively.

A phenolic resin industrial wastewater containing about 41,000 mg/l of phenol and 2,800 mg/l of formaldehyde was biologically treated by a mixed culture GE2 immobilized on ceramic beads. This study was carried out with three experimental groups : Control-only added the sludge of papermill wastewater ; GE2 treatment-added GE2 to Control ; Ceramic treatment-applied ceramic carrier to GE2 treatment. When the original wastewater was diluted 80 times with aerated tap-water, influent COD$_{Mn}$ WaS 1,140 mg/l and that of the effluent was in the range of 22-35 mg/l, which was not much different among the experimental groups. However, at 20-times dilution, influent COD$_{Mn}$ was 4,800 mg/l and the effluent COD$_{Mn}$ of Control, GE2 treatment and Ceramic treatment was 179, 128 and 94 mg/l, respectively. COD$_{Mn}$, removal efficiency by Ceramic treatment was the highest, at 98.0%. At this time, the effluent phenol concentration of Control, GE2 treatment and Ceramic treatment was 10.71, 7.93 and 5.60, respectively. As the dilution times decreased, the removal efficiency of COD$_{Mn}$ and phenol did not change much, but COD$_{Mn}$ and phenol concentration of the effluent increased. Consequently, it is likely that the phenolic industrial wastewater containing phenol and formaldehyde can be biologically treated using a GE2 and ceramic carrier and that at 40-times dilution, the effluent completely meets the effluent standards for industrial wastewater treatment plant.

The influx of Western culture and the food culture have altered the tableware of Korea, increasing the amount of using tableware. The representative tableware is known as bone china. Considering not only the amount of bone china waste generated from broken tableware at homes and but also faulty bone china products at factories, the bone china waste disposed in simple landfills is to be a serious environmental problem to solve. In this study, following "the research on development of ceramics body using waste celadon" of which the possibility was confirmed, development of ceramics body is conducted by recycling waste bone china. From the result of the study, it was understood that maximum addition of waste bone china was 20% of the whole material on the basis of measurement of plasticity. So 20% of pulverized bone china was added and the characteristics were evaluated, and the result was that porosity, water absorptivity and plasticity were 0.756%, 0.339% and 24.13%, respectively. Bending strength was $672\;kgf/cm^2$, which showed a good sintering condition. Therefore, it was considered that waste bone china could be utilized for development of new porcelain material.

Onggi, which is described as a breathing pottery, has strongly influenced the traditional food culture in Korea. In this study Onggi is compared to porcelains including celadon and white porcelain to analyze the sources of pore formation. The differences in starting materials are examined for chemical and mineralogical compositions, particle size and distribution. The gas permeability of the fired samples is correlated to the matrix microstructure. The broad particle size distribution and high iron oxide content of Onggi are revealed as the major cause for the pore formation. Open pores are formed with large particles in the Onggi body while closed pores have a high iron oxide concentration. The Onggi body with increased open pores leads to the high gas permeability.
