Oriental painting lesson is considered neglectedly, because of pressure on teachers and troublesomeness of preparing and using for art supplies. However, change of medium can solve pressure on teachers and students for Oriental painting lesson enough. Therefore this study will present composition of Oriental painting lesson planning using photoshop program as a way of overcoming weak points, increasing students' interests and giving effective composition lesson. We developed composition of Oriental painting lesson planning using layer of photoshop program. Then We surveyed 60 students who are two classes of the first grade in G high school to know the effect and possibility of the lesson planning and analyzed the results. The most(75%) of the respondents answered that composition of Oriental painting lesson planning using photoshop program was appropriate. The more than half (58.3%) respondents wanted to participated in lesson regardless of any subjects. That shows highly interest for photoshop program. The respondents answered that the merits of this lesson using photoshop program are less pressure for drawing(33.3%), possibility of variety expression(30%), not requiring art supplies(26.6%). So this study shows using photoshop program for art class can solve weak points of Oriental painting lesson.

Lipid composition was compared among rice varities such Dongjin, Jinmi and Tamjin as high, medium and low sensory quality, respectively Total and purified lipid contents of Jinmi were 1.7~2.2 times higher than those of Dongjin and Tamjin, and the lipid contents had not showed a tendency in the rice varieties with different sensory quality Dongjin of high sensory quality had high contents as 9.2~13.5% of neutral lipid and 3.1~4.7% of phospholipid, and low content as 12.3~18.2% of glycolipid compared with Jinmi and Tamjin of medium and low sensory quality. The rice varieties had not showed a tendency as a difference of sensory quality in compositions of neutral and phospholipid. As the sensory quality increased in the rice varieties, monogalactosyl diglycerides, steryl glycosides had high contents as 0.4~19.24% and 14.4~17.1%, and esterified steryl glycosides, celebrosides and digalactosyl diglycerides had low contents 15.3~28.1%, 1.2~5.7% and 2.8~3.8%, respectively, in glycolipid. Fatty acid composition also had no tendency as a difference of sensory quality of the rice varities in compositions of neutral and phospholipid. Palmitic acid, however, had a high content as 0.4~22.6% and linoleic acid had a low content as 5.0~12.0% in fatty acid composition of glycolipid.

Effects of retained austenite contents on ductility of medium carbon spring steels according to steel alloy compositions and heat treatment conditions were studied. Contents of retained austenite varied with steel compositions and heat treatment conditions, and some retained austenite were found to transform to martensite on stress. Reduction of area (RA) increased with contents of retained austenite, then saturated through its maximum, and subsequently decreased. Increase in RA with retained austenite contents could be due to crack blunting effect by retained austenite on stress, however, more contents of martensite transformed from retained austenite in its higher contents could cause decrease in RA.

Galaxy clusters as the densest and most prominent regions within the large-scale structure can be used as well characterizable laboratories to study astrophysical processes on the largest scales. X-ray observations provide currently the best way to determine the physical properties of galaxy clusters and the environmental parameters that describe them as laboratories. We illustrate this use of galaxy clusters and the precision of our understanding of them as laboratory environments with several examples. Their application to determine the matter composition of the Universe shows good agreement with results from other methods and is therefore a good test of our understanding. We test the reliability of mass measurements and illustrate the use of X-ray diagnostics to study the dynamical state of clusters. We discuss further studies on turbulence in the cluster ICM, the interaction of central AGN with the radiatively cooling plasma in cluster cooling cores and the lessons learned from the ICM enrichment by heavy elements.

A strain of alkalophilic Bacillus sp. C-21 has been Isolated from sold. The strain was capable of producing large amount of cyclodextrin glycosyltransferase (CGTase) in the high alkaline pH medium. The preferable medium composition was determined to be as follows : 1.0% soluble starch, 1.0% peptone, 0.5% yeast extract, 0.1% K2HP04, 0.02% MgSO4.7H2O and 1.0% Na2CO3(pH 10.0) The highest enzyme production was observed after 30hours of cultivation at 33$^{\circ}C$. The optimum temperature and pH for the activity of crude enzyme were 6$0^{\circ}C$ and 6.0, respectively. The enzyme was stable between pH 6.0 and 9.6, and up to 55$^{\circ}C$.

Cell growth of the marine microalga Tetraselmis suecica was regulated by the addition of seaweed extracts in its culture medium. Of 26 species of seaweed tested, water-soluble extracts from Monostroma nitidum and Pachymeniopsis elliptica and methanol-soluble extract from Sargassum confilsum enhanced the growth of T suecica cells. The water extract of M. nitidum was the most effective, producing up to a 2-fold increase in cell density with the addition of 1 mg/mL of extract to the culture medium. Cell size, gross biochemical composition, fatty acids, and digestion efficiency all differed marginally between cultures of T suecica grown with and without the M. nitidum extract.

The optimal medium composition for the production of carotenoid pigment from Haloarcular sp. EH 1 as a dietary for fishes were 1.0% sucrose, 1.0% yeast extract, 25% sodium chloride, 0.3% sodium citrate, 0.2% potassium chloride, 2.0% magnesium sulphate, 0.002% ferric sulphate(pH 7.0).

In order to obtain a strain of producing lipase which has resistance against alkaline and detergent, a screening test was carried out. Among 500 strains isolated from soil samples, the strain J-19 was selected for this study. The composition of the optimum medium for the highest lipase production was 2.0% glycerin, 1.0% corn steep liquor, 2.0% yeast extract, 0.1% $MgSO_4$ $7H_2O$, 0.2% $K_2HPO_4$, 1.5% soybean oil and 0.1% LAS(linear alkylbenzene sulfonate) with initial pH value of 10.0 and 3-day cultivation at $25^{\circ}C$. The lipase activity of the strain J-19 under optimal condition was 3.3. units/ml, which was increased about 1.3-fold than that of basal medium.

This paper evaluates the economic effect of the IT SoC Industrial Foundation Composition Project. The evaluation was done in three steps. The first step was to estimate the contribution effect of the fabless small and medium venture business' sales. The step includes interview with all the CEOs of the firms under the support of the Enterprise Incubation System, The second step was to apply input-output analysis and then estimate the production inducement effect. The last step was to compare the results of estimation with the costs of the project. We have concluded this project had achieved 6.3 times greater economic effect compared to the budget. The reason for the large economic effect is that the project provided various infrastructures to the small and medium venture businesses.

In order to increase the productivity of cellulolytic enzymes, medium composition and culture conditions were studied. When cellulose powder (Avicel) supplemented with rice straw was used as carbon source, productivity of ${\beta}-glucosidase$ was increased by about 3 times compared with the runs with only cellulose powder as a carbon source. In this case no negative effects on the production of CMC enzyme activity and filter paper activity was found. For the production of celulolytic enzymes using T. reesei QM 9414, casitone was found to be a good nitrogen source compared with other sources studied, such as peptone, yeast extract, tryptone, and casein. The highest cellulase activity was attained when 0.3% glucose and 0.01% Tween 80 were supplemented to the standard medium of Rese. An adequate oxygen transfer rate was also found to be important to the cellulase fermentation and about 50 mmole of oxygen/liter/hour supported good cellulase biosynthesis during cellulase fermentation.
