In this study, four types of water-heavy fuel oil hybrid emulsion oil were manufactured depending on the moisture content ratio in order to reduce exhaust emissions of heavy fuel oil(Bunder-C), which is necessarily used in vessels, power plants and boilers. The components of the manufactured emulsion oil were analyzed using the ISO standard testing method. The analysis result showed that in the EM25 fuel with a maximum moisture content ratio of 25.0%, the moisture content was 25.0%, the sulphur content was 0.20%, the kinematic viscosity was 144.8mm2/s, the specific gravity was 0.9382, and the flash point was 100 Celsius degrees or above.

The value of using rice flour processed into rice powder in preparing porridge was evaluated by measuring the moisture content, pH, total starch, reducing sugar, and color content. The moisture content of the rice flour and the pH of porridge made with rice flour were measured. Rice flour contained 77.55% moisture and the moisture content of the porridge made from rice flour processed into rice powder was 91.40 to 92.47%. The pH of rice flour porridge was acidic at 6.53 to 6.95. The color of the porridge was also measured. The L* values ranged from 82.62 to 97.55, the a* values ranged from －0.09 to 0.08, and the b* values ranged from －2.74 to 1.91.

The purpose of this study was to investigate the effects of nine times repetitive steaming and drying process Sunsik diets on antioxidant activity in obese mice fed high fat diets to prevent oxidative stress, using drying materials comprising 23 kinds of cereals (61.5%), beans (30.0%), sweet potato and potato (3.0%), fruits (2.0%), vegetables (3.0%), and stevioside, a natural sweetener (0.5%). We produced three samples: the experimental group was classified into the normal diet group (control), the high fat diet group (HF), and the high fat diet group + the Sunsik group (3HFS, 7HFS, 9HFS) fed to the mice for eight weeks. As a result, the serum, liver lipid peroxide, and nitric oxide levels were significantly higher in the HF group than in the C group at p<0.05 level, and the NO level was lower in the Sunsik supplemented groups. The antioxidant enzyme catalase activity significantly decreased in the HF group at the p<0.05 level compared to the C group. The total antioxidant activity of the C group was significantly higher in serum, liver, and kidney tissues than the HF group (p<0.05). The anthocyanin level in liver and spleen tissue was significantly higher in the group fed Sunsik than in the HF group.

UO2 kernels, a key component of fuel elements for high temperature gas cooled reactors, have usually been prepared by sol-gel methods. Sol-gel processes have a number of advantages, such as simple processes and facilities, and higher sphericity and density. In this study, to produce 900 μm-sized UO2 particles using an external gelation process, contact length extension of the NH3 gas of the broth droplets pass and the improvement of the gelation device capable of spraying 14 MNH4OH solution are used to form 3,000 μm-sized liquid droplets. To produce high-sphericity and high-density UO2 particles, HMTA, which promotes the gelation reaction in the uranium broth solution, is added to diffuse ammonium ions from the outside of the gelation solution during the aging process and generate ammonium ions from the inside of the ADU gel particles. Sufficient gelation inside of ADU gel particles is achieved, and the density of the UO2 spheres that undergo the subsequent treatment is 10.78 g/cm3; the sphericity is analyzed and found to be 0.948, indicating good experimental results.

The purpose of this study was to evaluate the quality properties of Meju prepared by inoculating two strains of Bacillus amyloliquefaciens HJ5-2, and Aspergillus oryzae PS03. The three soybean varieties that include Daewonkong, Daechan, and Saedanbaek were used in this experiment. The fermentation temperature during the Meju aging varied at 20℃, 30℃, and 40℃, respectively. The physicochemical analysis of the soybeans, showed that the cured protein and fat contents were 34.83~43.49% and 12.91~18.90%, respectively. The pH and total acidity were 6.47~6.93 and 0.11~1.22%, respectively. The change in appearance of the Meju was that the yellow-green mold was well formed on seven days at fermentation temperature of 20℃ and 30℃, but at 40℃, there was minimal mold formation and cracking of the surface. The amino nitrogen content was highest on the Daechan Meju at 621.83 mg% for seven days. The amylase increased as the fermentation period increased in all samples, and the protease increased rapidly until the first day of the fermentation, and then gradually increased thereafter. The total number of bacteria increased or decreased as the fermentation proceeded to 6.66~10.07 log CFU/g. The mold counts increased with increasing fermentation period in the range of 6.38~8.79 log CFU/g.
