Correlation of hydrolysis rate, total solid content and Volatile fatty acid yield in anaerobic digestion of papermil1 sludge using Rumen microorganisms and conventional acidlogenesis were summarized as follows ; 1. Ultimate volatile fatty acid yield and hydrolysis rate produced by rumen microorganisms and conventional acidogenesis were about 7.2megVFA/gVS. 0.175-1 and 6.8meqVFA/gVS, 0.103d-1. Therefore, hydrolysis rate by rumen microorganisms was 1.7times faster than that of conventional acidogenesis. 2. During the operating, VFA composition ratios(%) produced by rumen microorganisms were acetate:propionate:butyrate=64=5: 27±7: 9±2. At 5,10,13 and 6.83meqVFAg/VS, respectively. 3. When effluents produced by MAR and RMR were anaerobically digested, methane yields were 0.27 and 0.29 ℓ CH₄/gCOD_(rem) respectively.

Slaughterhouse wastewater containing high ammonium ion concentration and organic matter was treated by upflow anaerobic sludge blanket(UASB) reactor. As organic loading rate(OLR) was increased from 0.25㎏COD/㎥·day to 8.0㎏COD/㎥·day, COD removal efficiency was about 80 percent. But in case of OLR increased up to 8.0 ㎏COD/㎥·day, organic removal efficiency was decreased. In case of OLR was increased from 0.25㎏COD/㎥·day to 8.0㎏COD/ ㎥·day and ammonium loading rate was increased from 0.02 ㎏ NH₄^(+)-N/㎥·day to 0.62 ㎏ NH₄^(+)-N/㎥·day, effluent ammonium ion concentration was decreased from 1800㎎/l to 720㎎/l. Biogas production was increased form 0.248 ㎥/㎏COD_(rem) to 0.280 ㎥/㎏COD_(rem) in case of OLR was increased from 0.25 ㎏COD/㎥·day to 6.0 ㎏COD/㎥·day. Methane, carbon dioxide and ammonia gas content were 49%, 49% and 2.0% respectively in initial OLR was 0.25 ㎏COD/㎥·day but ammonia gas does not produced in case of OLR was increased up to 4.0 ㎏COD/㎥·day. In proportion to decrease hydraulic retention time, MLSS concentration in upflow anaerobic sludge blanket reactor was increased.

Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

Fruit are normally kept in a pouch of cold storage room in winter. In this work, a mathematical model that is emulating the fruit respiration in the pouch of the storage has been established. The calculated result is compared to the actual measured gaseous composition change of pear in the packaging pouch LDPE film incorporated with silver coated ceramic powder. The presented model, that is combining polysaccharide digestion kinetics in pear, Fickian diffusion for permeation of the film and sigmoidal adsorption equilibrium between the film and gases, predicts the respiration of the pear in the packing film fairly well.
