Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

This paper aimed to find out the eco-friendly approach enabling to directly print patterns and dye colors on fabrics using leaves of plants. In the research process, I found out the 'eco-printing' which could effectively express unique colors and patterns of plants. While eco-printing can design the patterns and colors of plants in nature using the leaves of plant(Eucalyptus), it is difficult to implement because it is not systematically and academically investigated including the dictionary definition in Korea until now. Thus, I tried to define the eco-printing and natural dyeing using leaves or flowers of plants enabling to get natural patterns and colors and do the experimental research and production using the leaves of Eucalyptus. The leaves of Eucalyptus were arranged on a wool scarf and a silk scarf, tied and applied pressure to them and made pigments penetrate into fabrics by heating or steaming them. This approach is to directly print the patterns using the shapes of plants on fabrics unlike the existing approaches dyeing by extracting dyeing solution from natural materials. Furthermore, the change of colors was attempted by using the color fixers. In accordance with the results of this experimental research, the scarf design differentiated from the existing products could be acquired. It was identified that eco-printing could induce the color variables depending on the conditions of each material and environment. For improving the color variables, various kinds of fabrics and divers kinds of materials which can be easily acquired in a daily life will be investigated and compared. Furthermore, it is expected that the experimental research and production techniques on eco-printing be utilized when starting natural dyeing and the scope of natural dyeing be more expanded.

Since 1990's, a plywood for flooring base has gotten customers' demand. Costs of raw material and production increased because of changed environment of industry. Tropical timber such as Red Meranti (Shorea acuminate) used for raw material of the floor has been depleting beside countries in South Eastern Asia changed species of afforestation. As a result, it gets hard to secure good quality of raw material for plywood. Moreover plywood price is increased suddenly after earthquake in Japan. Eucalyptus (Eucalyptus globulus) in china has been using for raw material as a countermeasure of changed environment of industry. In this study, possibility of using flooring consisted of Eucalyptus veneer as crossband layers was checked by deflection experiments. Flooring consisted of Red Meranti was used for comparison. Two factors which impact on deflection are a type of density gradient and density difference between Long-grain veneer and Short-grain veneer. Red Meranti samples are M type of density gradient on the other hand Eucalyptus samples are W type of density gradient. The more samples have high density difference, the more deformation was checked. A sample which has big density difference between core and cross bands layer warp more also deform. Flooring was deformed smaller than plywood and samples which have big density difference was deformed more.

The application of bioreactor culture techniques for plant micropropagation is regarded as one of the ways to reduce production cost by scaling-up and automation. In an attempt to optimize mass proliferation systems in Eucalyptus pellita, four types of bioreator systems including temporary immersion system with or without net were tested. Highest growth was achieved with 30-min flushes of medium at every 4-h intervals in TIN (temporary immersion with net) system. Results indicate over three-fold increase in shoot growth with the TIN system when compared with TIX (control: temporary immersion without net) system which is without net in bioreactor. Furthermore, plants produced from the TIN system increased total chlorophyll content, chlorophyll a/b and dry matter, giving higher yields of acclimatized plants. Our findings suggest that plantlet growth increases with appropriate exposure to media at correct intervals, as well as use of net for maintaining aerobic condition in the vessels. The TIN system thus has great potential for in vitro mass production of Eucalyptus clones commercially.

This study was conducted to develop stem taper equations and stem volume tables for Eucalyptus pellita and Acacia mangium plantations in Kalimantan, Indonesia. To derive a most adequate taper equation for the plantations, three models - Max & Burkhart, Kozak, and Lee models - were applied and their fitness were statistically analyzed by using fitness index, bias, and standard error of bias. The result showed that there is no significant difference between the three models, but the fitness index was slightly higher in the Kozak model. Therefore, the Kozak model was chosen for generating stem taper equations and stem volume tables for the Eucalyptus pellita and Acacia mangium plantations. The resulted stem volume table was compared to the local volume table used in Kalimantan regions, but no significant difference was found in the stem volume estimation. It is expected that the results of this study would provide a good information about the tree growth in abroad plantations and support a reliable decision-making for their management.

A total of 39 essential oils were tested for antifungal activities as volatile compounds against five phytopathogenic fungi at a dose of 1 ${\mu}l$ per plate. Five essential oils showed inhibitory activities against mycelial growth of at least one phytopathogenic fungus. Origanum vulgare essential oil inhibited mycelial growth of all of the five fungi tested. Both Cuminum cyminum and Eucalyptus citriodora oils displayed in vitro antifungal activities against four phytopathogenic fungi except for Colletotrichum gloeosporioides. The essential oil of Thymus vulgaris suppressed the mycelial growth of C. gloeosporioides, Fusarium oxysporum and Rhizoctonia solani and that of Cymbopogon citratus was active to only F. oxysporum. The chemical compositions of the five active essential oils were determined by gas chromatography-mass spectrometry. This study suggests that both E. citriodora and C. cyminum oils have a potential as antifungal preservatives for the control of storage diseases of various crops.
