  • Environment friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials we, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For examples, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural materials. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21century through recycled and reused materials.

  • The purpose of this thesis is to suggest the new orientalism fashion through the comprehensive approach to analyze the art of the Tang dynasty, China. Tang dynasty has high culture, economy, polity and art. Also the character of Tang's culture is very international. Therefore that point is coincide with fusion culture in the early 2000's. As a method of accomplishing this research, the documents and fashion magazines related to the art and fashion were examined. Through analyzing the art in the Tang's related to fusion culture, reach a conclusion that the modern fashion has four characters. 1. The cause of high culture and economy, the trend of fashion was decorative 2. The cause of realism, the trend of fashion were modern and simple. 3. The cause of rhythmical line, the trend of fashion had natural drape. 4. The cause of globalism, the trend of fashion mixed east with west This research keep going for showing new orientalism and coinciding with 21th century's trend.

  • Decay and mold resistance of zinc borate (ZB) and calcium borate (CB) modified oriented strandboard (OSB) from southern mixed hardwood and southern yellow pine was investigated in this study. Brown rot fungus Gloeophyllum trabeum and white-rot fungus Trametes versicolar were used to examine the decay resistance of the OSB. The OSB test specimens were colonized by brown and white rot fungal mycelium in both the brown and white-rot culture bottles after 8 and 12 weeks, respectively. The wood species and fungus type had the significant effects on the decay resistance. Brown rot decay was evident for all untreated southern pine and mixed hardwood controls. The white-rot decay, however, did not show significant weight loss at both species control samples. The incorporation of ZB and CB composites provides suitable protection against brown-and white-rot fungi. No significant weight loss was observed from the borate treated OSB.

  • The effect of silver ion solution on the growth of Microcystis aeruginosa UTEX 2388 (cyanobacterium) and Chlorella sp. KCTC AG20136 (green alga) was investigated using separated and mixed culture in filtered natural water and BG11 medium. In separated culture, M. aeruginosa UTEX 2388 and Chlorella sp. KCTC AG20136 were found to be sensitive to 0.01 and 0.1 mg L$^{-1}$ of silver ion, respectively. Also, the silver ion concentrations for the growth inhibition of M. aeruginosa UTEX 2388 and Chlorella sp. KCTC AG20136 in the mixed culture were same in separated culture. Cyanobacteria were more sensitive to the silver ion solution than green algae. In bloom sample, the minimal inhibition concentration of silver ion solution for the low Chl-${\alpha}$ sample (110$\sim$190 ${\mu}g$ L$^{-1}$) and high Chl-${\alpha}$ sample (1,500$\sim$1,900 ${\mu}g$ L$^{-1}$) was about 0.1 and 3.0 mg L$^{-1}$, respectively. The silver ion concentration for the inhibition of algal bloom sample was affected by the algal biomass. In order to use silver ion solution for the control of algal bloom, the silver ion concentration must be determined in consideration of a minimal effect on the environment.

  • The purpose of this research is to revive the colors of combination dyeing and mixed dyeing with natural dyestuffs. The fabrics used were cotton and rayon. The natural dyestuffs used in this research were indigo, Phellodendron amurense, and Caesalpinia sappan. The effects of combination dyeing were as follows. First, all samples showed deeper colors. Second, according to the results of the surface K/S measurement, while the surface K/S of cotton was over 15, that of rayon was over 17. Third, the results of the light fastness measurement showed the superiority (by over grade 4) of all the samples, except in the case of rayon fiber sample no. 6 (which had been pre-dyed with indigo five times before being dyed with P. amurense once and then being dyed with C. sappan once). In the color fastness to washing measurement, all fibers showed superiority (by over grade 3~4). In addition, the color fastness to dry cleaning of all fibers was satisfactory or excellent (by over grade 3). Fourth, according to the results of the tensile strength measurement, it tended to decrease in the case of cotton and increase in the case of rayon. Fifth, the results of the density measurement showed that the density of cotton decreased by about 15~20% in the case of warp and 10% in the case of weft for all samples. The density of rayon decreased 20% in the case of warp for all samples and increased 30% in the case of weft for all samples.

  • The purpose of this study is to investigate effects of natural incense on the preservation of paper- and textile-based remains and the kinds and applications of natural anti-insect incense by reviewing relevant literatures of the ancient times. There are few ancient literatures of incense published in Korea. The researcher deducted how incense was used in this nation through reviewing verses contained in ancient literatures and medical books. In contrast, the kinds and applications of anti-insect incense used in China, where incense culture prospered, were investigated here through reviewing technical books about incense published during the Song(宋) and Ming(明) periods, $\ll$Incense record(香譜)$\gg$, $\ll$Chen's Incense record(陳氏香譜)$\gg$ and $\ll$Incense record(香乘)$\gg$. There were several methods of keeping clothes better from insects. In relation, how to use anti-insect incense varied in accordance with main materials of clothes, paper, textile, leather and others. Cymbopogon dstans(芸香), Brassica rapu var and Incarvillea sinensis(角蒿) are anti-insect incense which were used for paper. Anti-insect incense for textiles is classified into single and mixed incenses depending on whether only one kind of incense was used or more than seven kinds of the substance. Acori rhizoma(菖蒲), Capsella bursa-pastoris(薺菜花), Lactuca sativa L., Erigeron canadensis(莽草), Stemona japonica(百部) and Moschus sifanicus(麝香) are single anti-insect incense which were used for textile. While, the latter was called. ‘Yi Xiang(衣香)’ is mixed anti-insect incense which was used for textile. Artemisia asiatica(艾葉) and Zanthoxylum schinifolium(花椒) are anti-insect incense which were used for leather. Angelica dahurica(芳香) and Bamboo are anti-insect incense which were used for others. There were three main methods of using incense to prevent insects, that is, diffusing incense's strong scent and ingredients, exposing to smokes from burnt incense and washing with incense-boiled water. Diffusing incenses had a strong scent and antibiotic ingredients, which were put between books or clothes or into a storage box without being processed. If necessary, however, they were processed into rough powders that were in turn used singly, or otherwise mixed for a stronger scent and better insect elimination. Exposing to smokes from burnt incense was done as follows. A clothes was put on 'Long(籠)' underneath which there was a boiling water. The clothes was humidified by the water and then exposed to smokes from burnt incense. 'Long(籠)' had been long used since it was manufactured in the QinHan(秦漢) period for the first time. A local literature, $\ll$Koryo TuGing(高麗圖經)$\gg$ shows that in the Koryo(高麗) period, BoShaLu(博山爐) were used as a means of exposing clothes to smokes to prevent moths, similarly to China. Washing clothes with incense-boiled water was more effective in removing lots of worms and germs from clothes, but leaving the scent and ingredients of the used incense and maintaining the effect of anti-insect.

  • A microbial strain capable of degrading ABS (alkyl benzene sulfonate) was isolated and identified as Pseudomonas caryophylli. During the incubation of the isolated bacterium in a synthetic effluent containing 10 ppm of ABS, the extents of removal of ABS, BOD and COD were 40%, 89% and 71%, respectively. The degradability of ABS by pure culture with the isolated strain was twice higher than that of mixed culture with natural microflora. The biodegradability of some commercial detergents in Korea by the isolated organism was as follows: Hiti 46.2%, Kleenup 37.5%, No.1 29%, and OK 27.9%.

  • Heavy metal adsorptions of four streptomycetes were compared with each other, Among the test strains, Streptomyces viridochromogenes showed the most efficient metal binding activity, which was carried out by cell wall as well as freeze-dried mycelium. An order of adsorption potential (zinc > copper > lead > cadmium) was observed in single metal reactions, whereas this adsorption order was disturbed in mixed-metal reactions. The metal adsorption reactions were very fast, pH dependent and culture age-independen, suggestive of a physico-chemical reaction between cell wall components and heavy metal ions. The metal tolerant stains presented the weakest adsorbing activity, indicating that the metal biosorption was not the basis of the metal tolerance.

  • A 12-year-old, castrated male, mixed-breed dog was referred to us with a history of depression, lameness, neck and multiple joints pain. Clinical signs had been deteriorating from rear limbs lameness leading to pain on all four limbs lameness for 7 days. Mild leukocytosis and increased C-reactive protein concentration were revealed in blood work. On radiography, degenerative change of humerus and cervical intervertebral space narrowing were found. The results of synovial fluid analysis revealed severe neutrophilic pleocytosis, decreased viscosity, increased turbidity and bacterial culture was negative. The antinuclear antibody test was negative and MRI results revealed mild cervical intervertebral disk disease (IVDD). Based on all tests, we diagnosed this case as idiopathic immune-mediated polyarthritis (IMPA). Prednisolone and mycophenolate mofetil were administered and clinical signs were resolved after 7 days. This case report demonstrated that clinical, diagnostic imaging and synovial fluid analysis findings and successful treatment result with prednisolone and mycophenolate mofetil in canine idiopathic IMPA.

  • We have also clarified the effects of the different substrates; (perlite, peatmoss and granular rock-wool) on the plant growth and the mineral contents of Campanula takesimana until 70 days after transplanting. Overall plant growth in terms of plant height, stem diameter, number of leaves, root length, fresh and dry weight of shoot and root were increased in the order of that mixed perlite and peat moss (50 : 50, v/v)>peat moss (100%)>perlite (100%)>granular rock wool (100%). Mineral contents in plants were much more in the order of potassium $(15.38-43.91cmol^+/kg)$, calcium $(5.48-7.78cmol^+/kg)$, magnesium $(4.38-6.55cmol^+/kg)$ and sodium $(1.25-1.69cmol^+/kg)$. The higher mineral contents of plants were also most made in the mixed substrates of perlite and peat moss (50 : 50, v/v).
