A case of huge ovarian cyst in 45 years old multiparous woman is presented with a brief review of literatures. This woman was admitted to our clinic with the complaints of marked abdominal distention which progressed rather rapidly: during recent two years. The woman was operated upon abdominally by the author. The tumor was removed surgically after puncture aspiration of the cystic contents before and during the operation. The tumor weight was 29.5 kg. and the volume' of cystic contents were about I1 L. Microscopic sections showed multiloculated mucinous cy stadenoma of the left ovary. The postoperative condition was uneventful and the patient was discharged on the tenth postoperative day.

A new heterogeneous Fenton catalyst, Fe-impregnated biochar catalyst (Fe-BC) was synthesized andevaluated in detail for its catalytic activity with sulfate radical under various conditions. The optimumconditions for the removal of Eriochrome Black T (EBT) by Fe-BC were determined as 0.27 g/L K2S2O8 (PS)and 0.5 g/L Fe-BC for 0.1 g/L EBT, and which resulted 85–88% removal efficiency within 2 h. The effectiveoxidation of EBT was observed over a pH range of 2–4 and temperature of 25–45 C and maintained EBTremoval efficiency of 77.6–92.7%. Under optimum conditions, the catalytic activity was faster in the orderof PS > PS + HP > H2O2 (HP) >>Fe-BC (without oxidants). The catalytic activity of Fe-BC for EBT can beidentified in two stages, which occur rapidly within 30 min (1st stage) and followed by slow oxidationuntil 120 min (2nd stage). Catalytic activity by sulfate radical was also dominantly influenced by otherpollutant such as iodide, phosphate and humic acid. Overall, the sulfate radical generated from Fe-BC/PSwas found more economical with strong oxidation efficiency for use in Fenton-like reaction for treatingorganic pollutants compared with conventional Fenton reaction with H2O2.

In order to develop constructed wetlands for treating hydroponic wastewater in greenhouses, removal efficiencies and decomposition velocities of pollutants in constructed wetland were investigated for treating hydroponic wastewater. Removal rates of BOD, COD, SS, T-N and T-P in effluent in constructed wetlands were 88%, 79%, 92%, 64% and 92%, respectively. The decomposition velocities (K; day-1) of pollutants in 1st HF bed of constructed wetlands were higher in the order of SS (0.54 day-1) > BOD (0.39 day-1) > COD (0.27day-1) > T-P (0.26 day-1) > T-N (0.06 day-1). In 1st HF bed of constructed wetlands, the decomposition velocity of SS was rapid than that for BOD, COD, T-N and T-P in constructed wetland for treating hydroponic wastewater. The decomposition velocity (K; day-1) of pollutants in 2nd HF bed of constructed wetland were higher in the order of T-P (0.52 day-1) > BOD (0.28 day-1) > COD (0.15 day-1) > T-N (0.06 day-1) > SS (0.10day-1). In 2nd HF bed of constructed wetlands, the decomposition velocity of T-P was rapid than that for BOD,COD, SS and T-N in constructed wetland for treating hydroponic wastewater.

In order to obtain optimum pre-treatment methods and improve T-N and T-P removal efficiencies, removal rates of pollutants in small-scale livestock wastewater treatment apparatus with water plant filtration bed or activated sludge tank were investigated. Based on the results from the optimum pre-treatment in small-scale livestock wastewater treatment apparatus, removal efficiencies of pollutants in livestock wastewater treatment plant with water plant filtration and activated sludge beds. The removal rates of COD, SS, T-N, and T-P in effluent were 83, 89, 63 and 87% in small-scale livestock wastewater treatment apparatus with water plant filtration bed, respectively. The removal rates of COD, SS, T-N, and T-P in effluent were 96, 95, 86 and 92%in small-scale livestock wastewater treatment apparatus with activated sludge tank, respectively. For increasing the COD, SS, T-N, and T-P removals in small-scale livestock wastewater treatment apparatus, the water plant filtration and activated sludge beds are recommended. In livestock wastewater treatment plant with water plant filtration (1^st treatment) and activated sludge (2^nd treatment) beds, the concentrations of COD, SS,T-N, and T-P in effluent were 39, 15, 42 and 1 mg L^-1, respectively. It was shown that the concentrations of COD, SS, T-N, and T-P met acceptable effluent quality standard for livestock wastewater. Based on the above results, the removal rates of COD, SS, T-N, and T-P in effluent were over 99.8, 99.9, 99.2, and 99.9% in livestock wastewater treatment plant, respectively.

The subject of healing has not been popular among Christian writers and scholars for various reasons. Protestant Reformers made little mention of Jesus’ identity as a healer, because they were critical of the magical elements of Roman ritual and its political mistreatment. Sometimes sober ecclesiastics condemned the enthusiasm for healing miracles, interpreting healing not as the restoring of bodies but as the treating of the soul. I argue that that healing should be acknowledged from the standpoint of religion and medicine together because both concentrate on suffering and salvation from distressed conditions. Healing continues to be a characteristic feature of Christianity and has included an important cultural component because it makes use of cultural practices and images. The complex way we engage in human experiences constitutes the meanings of those experiences. To the extent that these new meanings encompass the person’s life experience, healing creates changed or transformed realities. To understand this restoration process in the ancient Near Eastern world, for example, one needs to pay attention to the core social values such as honor and shame, the gender-based division of society, belief in spirits, attitudes toward pain, and many other values and concepts. In this paper, I argue that thought, memory, emotion, and imagination have the same root as the expression of our being in a specific community or culture. These modes of perception played an important role for the healing experience as internal/external carriers of “meanings.” In this paper, I will focus on how strong emotions affect patients’ interpretation of religious experience and how cultural formulation of belief and memories shape and make possible their interpretation of illness experience.
