This study was carried out to evaluate the pollutant removal efficiencies of the advanced drinking water treatment using ozonation process. For raw water, Nakdong River was used. By conducting batch test of ozonation efficiencies of the ozonation were 94 to 92%, respectively. Removal efficiencies of single VOC compound or mixed VOC compounds in the raw water were 80% to 90% by the ozonation with 2 mg/ℓ dosage and 10 minutes contact time. Removal efficiencies of ABS by the ozonation with 1 mg/ℓ, 3 mg/ℓ dosage and 20 minutes contact time were 83% to 96%, respectively. Almost 67% of chlorophyll-a at the concentration of 38.㎍/ℓ was removed by ozonation at ozone dosage of 1mg/ℓ for 20 min. considering the efficiency of ozone utilization and water treatment, the most effective ozonation could be obtained with high ozone dosage and short and short contact time.

임종주,이의수 동국대학교 산업기술환경대학원 1996 산업기술논총 Vol.3 No.-

The removal of trihalomethanes (THM) by air stripping was examined. Experimental variables studied for air stripping were air flow rate, initial THM concentration, and residence time. In batch aeration experiments, CHCl_3 rejection level was found to increase with an increase in air flow rate., residence time and temperature. In continuous aeration experiments, both rejection levels of CHCl_3 and CHBr_3 increased with an increase in air flow rate. For the maximum air flow rate used (air-to-water ratio=20), about 75% or the initial CHCl_3 was removed by aeration whereas only about 40% of the initial CHBr_3 was removed under the same experimental conditions. When doubling the residence time in each experiment, rejection levels of CHCl_3 and CHBr_3 were shown to be increased by a factor of 1.8 and 1.2 respectively. The CHCl_3 removal level was affected by its intial concentration and the effect was found to become more significant as higher air-to-water ratios were used during aeration. On the other hand, CHBr_3 removal was not greatly affected by the initial CHBr_3 concentration. Preliminary experimental results suggested that aeration could be an effective method for the removal of the more volatile THM component, CHCl_3 but some other method such as carbon adsorption must be accompanied in order to obtain a substantial removal of the less volatile THM component, CHBr_3.

This paper presents a sonar based map building method. The environment is a room or an area inside a building, which is composed of four types of geometric primitives(corners, edges, cylinders, and walls). We also assume the environment can be modeled into two dimensional map in terms of planes(walls), points(corner and edge), and circle(cylinder). In a real world where most of the object surfaces are specular ones, a sonar sensor suffers from a multipath effect which results in a wrong interpretation of the location of an object. To reduce the effect and uncertainty, the method employs a simple thresholding technique for extracting circular are features called regions of constant depth(RCD) from scanning sonar data. The usefulness of the approach is illustrated with the results produced by sets of experiments.

Asthma is a chronic inflammatory disease of the airways, characterized by airway eosinophilia, goblet cell hyperplasia with mucus hypersecretion, and hyper-responsiveness to both inhaled allergens and nonspecific stimuli. Eosinophil are important in the pathogenesis of asthma, with release of inflammatory mediators such as histamine, leukotrienes, cytokines, and IgE after exposure to allergen. Objectives : This research investigates the effect of the extract of Duchesnea chrysanta (EDC) on OVA-indued asthma murine model. Methods : After i.p of C57BL/6 mice, OVA sensitization (day 0) were challenged intratracheally with OVA on days 8 and 21. EDC administered weeks 8, blocked the airway inflammatory response to OVA assessed 24 h after the last OVA challenge on day 22. Results : The CC chemokine receptor 3 (CCR3) is expressed by eosinophils, mast cells, and Th2 cells. The role of CCR3 in a murine model of allergic skin inflammation induced by repeated epicutaneous sensitization with ovalbumin (OVA), and characterized by eosinophil skin infiltration, local expression of Th2 cytokines, and airway hyperresponsiveness (AHR) to inhaled antigen. The administration of EDC during OVA inhalation significantly reduced CCR3 plays an essential role in eosinophil recruitment to the skin and the lung and in the development of AHR.. EDC extract reduced total lung cells and eosinophils in bronchoalveolar lavage fluid, airway tissue eosinophilia, goblet cell hyperplasia, mucus secretion, and peribronchial edema. The inhibitory effect on airway eosinophilia and AHR was associated with reduced levels of IL-4, IL-5, and IL-13 in the bronchoalveolar lavage fluid as well as reduced serum levels of OVA-IgE. We show that OVA inhalation following OVA immunization increased airway responsiveness to induced IL-113, IL-4 and IL-5 mRNA expression in the lung tissue. The administration of EDC during OVA inhalation significantly reduced this increased airway hyperresponsiveness and also inhibited airway inflammation. Conclusions : These results support EDC as a therapeutic target in asthma and indicate that selective EDC inhibitors can reduce allergic airway inflammation.

This paper presents a sonar based map building method. The environment is a room or an area inside a building. which is composed of four types of geometric primitives(corners. edges. cylinders. and walls). We also assume the environment can be modeled into two dimensional map in terms of planes(wal1s). pointdcorner and edge). and circle(cy1inder). In a real world where most of the object surfaces are specular ones. a sonar sensor suffers from a multipath effect which results in a wrong interpretation of the location of an object. To reduce the effect and uncertainty. the method employs a simple thresholding technique for extracting circular arc features called regions of constant depth(RCD) from scanning sonar data. The usefulness of the approach is illustrated with the results produced by sets of experiments.

Tumorous lesion of intra- and suprasellar area showed unique clinical pictures and also was very hazardous and difficult to remove surgically because of the surrounding important anatomical structures. Here, authors analyzed 28 confirmed tumor of this area during last two and half years retrospctively. Histopathologically, 28 cases were classified in 14 pituitary adenoma cased6 cases of non-functioning adenoma, 1 GH-secreting adenoma and 7 cases of prolactinoma), 7 craniopharyngioma cases, 3 meninigioma cases and each one case of germinoma, Rathke's cleft cyst, pituitary abscess and hamartoma. Sexual incidence was 6 : 22 in male vs female ratio. Twenty two cases were measured its diameter over 2cm and they extended to suprasellar area in all cases. Five cases of microadenoma were analyzed and they were all enclosed in sella turcica. Visual impairment was the most frequent and prominent clinical symptom. of which incidence was 78.57% (22 cases). The next frequent symptoms were headache and generalized lethargy. Diabetes insipidus was a presenting symptom in 4 cases and hydrocephalus was noted in 4 cases preoperatively. Surgical intervention was carried out in 23 cases, by the way, the performed type of surgery in 21 cases was a conventional transcranial frontotemporal(pterional) microsurgical method. Post-operatively, diabetes insipidus was complicated in 78.26 % and pituitary hypofunction was noted 34.78%. Two cases of intracranial hemorrhage was developed after surgery and one was died. Through 6 to 28 months follow up. 82.1 % of cases were improved in its clinical status including 7 cured cases.
