The present study has been conflicted to verify the applicability of tire powder and food waste compost as biofilter materials to degrade volatile organic compounds. Batch and column tests were performed to determine the optimum ratio of tire powder to compost and the appropriate mixing type of two materials for removal of the selected VOCs, i.e., benzene, ethylbenzene, PCE, and TCE. According to batch tests, tire powder and compost mixture had faster removal rate than the compost. The biofilter column filled with tire powder and compost showed better VOC removal efficiency than that filled with only tire powder. In this study, the best removal rate was observed in the sandwich type column test of which the tire : compost weight ratio was 1:2

This study was designed to determine amino acid composition of silkworm larvae protein and to evaluate its nutritional value by rat experiment. Diets were divided into 5 groups; casein ($D_1$), soybean protein ($D_2$), soybean protein+20% silkworm larvae ($D_3$), soybean protein+40% silkworm larvae protein ($D_4$), and silkworm larvae protein ($D_5$). The growth rate, protein efficiency ratio, weight of organs, hematology, and the content of total serum protein and albumin were studied. The amino acid composition of silkworm larvae protein was comparable to the FAO provisional scoring pattern. The protein was especially high in the amount of lysine and methionine indicating that it could be a good supplemental effect for cereals and beans. Growth rate and protein efficiency ratio of silkworm larvae protein were better than soybean protein and these were increased by the addition of silkworm larvae protein. The weight of liver and spleen from silkworm larvae protein group were also higher than soybean protein group and RBC, WBC, Hct and Hb content of 5 groups tested were within the normal ranges. The contents of total serum protein and albumin from soybean protein group were increased by addition of silkworm larvae protein. From the results obtained, it could be stated that the quality of soybean protein might be improved by silkworm larvae protein.

The effects of the mixture ratios of swine manure and food wastes when vermicomposed on earthworm(Eisenia foefida) growth, the production amounts and the chemical properties of casts for plant growth media were evaluated to optimal mixture ratio. Earthworms were grown in swine manure, substituted with 0%, 20%, 40%, 60%, 50% and 100% food wastes. All of earthworm grown in swine manure substituted with 60%, 80%, and 100% food wastes died, therefore the process of swine manure substituted with 60%, 80%, and 100% food wastes by vermicomposting were impossible in this experiment. Worm cast produced from swine manure substituted with 0%, 20% and 40% food wastes after vermicomposting sufficiently contained required quantities of available phosphorus, exchangeable potassium, exchangeable magnesium, and cation exchange capacity. The survival rates of earthworm in swine manure substituted with 0% and 40% food wastes was significantly higher than those in swine manure substituted with 20%, 40% food wastes. Casts weight and proportion of casts weight in 100% swine manure were significantly higher than those in swine manure substituted with 20% food wastes, but was no significant difference between those in swine manure substituted with 40% food wastes. Therefore 100% swine manure was estimated to be superior than the others treatments. However an adequate mixture ratio of food wastes for processing mixture of swine manure by vermicomposting was estimated to be 40%. Because there was no significant difference in mean flesh weight, increasing rate, casts weight, proportion of casts weight, and reduction rate of volatile solids among 3 treatments and survival rate and conversion efficiency(CE) in swine manure with substituted 40% food wastes were significantly higher than the other treatments.

Objectives : Laser therapy started in 1958 when Schawlow and Townes suggested medical value of Laser therapy. He-Ne laser has been utilized as a clinical treatment for various diseases by Plog since 1975. Low Level Laser Therapy (LLLT) has been used as medication for controlling obesity in the Korean Medicine. So this study is planned to investigate the effects of LLLT on the level of serum lipid and weight gain Methods : Experimental groups were divided into normal group(Normal), high fat diet group(Control), high fat diet and LLLT by helium-neon (He-Ne) on the tail is carried out once a 2 day during 5 weeks. The animals were divided into six groups: no ischemia-induced and no LLLT-treated group (Normal), the ischemia-induced and no LLLT-treated group (Control), the ischemia-induced and 5 mW 5 min LLLT-treated group (LLLT5-5), the ischemia-induced and 30 mW 5 min LLLT-treated group (LLLT30-5), the ischemia-induced and 5 mW 10 min LLLT-treated group (LLLT5-10), 30 mW 10 min LLLT-treated group (LLLT30-10). The effect of LLLT is observed by weight gain, food intake, food efficiency, serum of lipid concentrations, liver function and HDL to total cholesterol ratio of rats fed high fat diet for 5weeks. Results : Body weight and food intake were decreased in LLL5-5, LLLT30-5, LLLT30-10. Food efficiency was decreased in LLLT30-10. The level of serum Triglyceride, Free fatty acid, AST, ALT, ALP were decreased in LLLT30-10. Serum HDL-cholesterol was increase in LLLT5-10, LLLT30-10. Also serum ALT was decrease in LLLT5-5 Conclusions : LLLT(30 mW-10 min) is effective on Body weight, food efficiency ratio, the level of serum lipid and protection of liver function by obesity induced by high fat diet, and LLLT(5 mW-5 min) act on decrease of Body weight, food intake and ALT.

The feasibility of utilizing food waste leachate as an external carbon source was tested to enhance biological nutrient removal from an industrial wastewater with an average flow rate of $164,800m^3/d$ and a low carbon/nitrogen ratio of 2.8. A considerable improvement in the removal of nitrogen and phosphorus was observed when a certain amount of the leachate, ranging from 70 to $142m^3/d$, was supplemented to the biological industrial wastewater treatment process. The addition of the leachate led to an increase in the BOD/N ratio (4.5) and the removal efficiency of nutritents from 29.7% to 71.7% for nitrogen and from 34.8% to 65.6% for phosphorus. However, an excessive dose of the leachate that significantly exceeded $120m^3/d$ caused serious operational problems, like oil-layer formation in the grit chamber and scum layer in the primary clarifier. Thus, an supplement of food waste leachate at a dose acceptable to an existing facilities can be a practical and effective means to enhance the nutrient removal from industrial wastewater and to dispose of the food waste leachate.

This study was performed to define the effects of the cattle feces on aerobic composting of food wastes in vessel system. Weights of cattle feces added to food wastes of 3kg were 0.25, 0.50, 1.00 and 1.50kg, respectively. Reactors were operated with stirring for 1 hour per day by 1rpm and aeration for 2 hours per day. When the weight of cattle feces was increased, the highest temperature of sample was increased, the duration period of higher temperature was elongated, and the fluctuatio of pH was severs. When the weight of cattle feces was decreased, the final density was increased. The more cattle feces were added, the more porosity was increased, C/N ratio, salinity and conductivity were decreased. There facts denotes that the addition of cattle feces increases the efficiency of composting process and the final product of composting, namely compost.

Food waste contains almost no heavy metals and high fuel ratio 0.14-0.17 that makes it a good candidate for solid fuel. Thermogravimetric analysis showed that volatile matter volatilizes at $200-400^{\circ}C$, and ignition temperature is $460^{\circ}C$. Combustion efficiency measured from energy balance before and after combustion was over 99%. Pulverized fuel made from food waste is a new and renewable energy which contribute to low carbon green economic growth.

To study the influence of background color and substratum on hypermelanosis of starry flounder, we compared the daily food intake (DFI), the feed efficiency (FE), the survival, the growth, the ratio of pigmented area on the blind side and the ratio of hypermelanic fish duplicately reared for 180 days in dark-green FRP aquarium (control), white FRP aquarium together with dark-green substratum. The ratio of pigmented area on the blind side was significantly higher at the dark-green group than at the white group. DFI, FE and growth were higher in the dark-green substratum. Pigmented area rate and ratio of hypermelanic fish were significantly higher at the dark green group than at the high dark-green substratum. The results suggest that bright tank color and substratum bottom could inhibit the hypermelanosis.

The feasibility of enhancing biological nutrient removal from an industrial wastewater was tested with food waste leachate and sugar liquid waste as external carbon sources. Long term influences of adding external carbon sources were investigated to see how the biological nutrient removal process worked in terms of the removal efficiency. The addition of the external carbons led to a significant improvement in the removal efficiency of nutrients: from 49% to approximately 76% for nitrogen and from 64% to around 80% for phosphorus. Approximately, 20% of the removal nitrogen was synthesized into biomass, while the remaining 80% was denitrified. Though the addition of external carbon sources improved nutrient removal, it also increased the waste sludge production substantially. The optimal observed BOD/TN ratio, based on nitrogen removal and sludge production, was around 4.0 in this study.
