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.

Since 1990s there have been a lot of researches on Object-Relational Database System and Object-Oriented Analysis and Design methods for multimedia application systems. In this thesis, an unified analysis and design methodology for multimedia application systems, which is based on Object-Relational Database System. is proposed. For the unified methodology, both of Rumbaugh's OMT and Object-Relational Data Modeling method are combined and applied. Applying the modeling methodology to a very large system, we can develop an efficient DB system which guarantees the security and the safety. Moreover, this DB system is expected to have long life-cycle if the system is update continuously.

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 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.

The purposes of this study were (1) to reexamine what were found by the survey on KNU Teachers College Students after the Pilot School Project (Ⅰ) in order to assess the possibility of .generalizing results of the survey across different groups of students who enter Teachers College after the Pilot School Project was implemented, (2) and to examine students' opinion toward the current procedures of assingning freshemen to departments or majors of the Teachers College. The subjects were freshmen of KNU Teachers' College from 1975 to 1777 academic year. However, the data pertaining to the students from 1975 to 1976 had been gathered while the survey on Teachers College Students after the Pilot School (Ⅰ) was being carried out. In order to collect the data with regard to the students entered the Teachers College in 1977, four different questionnaives were employed. The data were statistically tested by means of chi-technique only when it seemed necessary and appropriate. Major findings of this study are as following: (1) After the Pilot School Project was employed, there were general tendency in students' reason applying for admission to KNU Teachers College: Each academic year, approximately 40% of freshmen decided to enter the college to be secondary school teachers in the future. (2) Students' attitude toward the new procedures of screening college applicants, which was employed after the Pilot School Project, were negative in general. Furthermore, their negative attitude became stronger year by year. (3) The degree of students' satisfaction with their majors were relatively higher than that expressed by the students who entered the college before the Pilot School Project was employed. (4) Both students' criteria for selecting their majors and then reasons for changing their majors which they had been interested in applying were varied across time subjects and time. (5) The obtained contingency coefficient between departments and GPA students of each department earned during thir freshmen year was 0.831. It seems to indicate that majority of freshment tends to choose their majors according to their GPA rather than their interest or aptitude. (6) Approximately 67.73% of freshmen of the 1977 academic year accepted the end of the academic year as the most appropriate time for assigning them to departments they desire to enter. 7) Approximately 52.10% of freshment supported the idea of assigningas many students to the departments as they wish to enter, as far as it is possible, by adjusting the capacity of department, which is regulated by MOE. (8) Approximately 61.08% of freshmen claimed not to deduct their GPA when their first choice of department became impossible and turned down to the second or the third one.

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.

There are a lot of shopping malls in Internet and most of consumers want to buy good goods in cheap price through the shopping malls. To support them, many sites for price comparison are constructed. But man or woman search many shopping malls and insert their price informations into database that the price comparison sites own. To overcome this disadvantage, virtual shopping malls are builded. These virtual shopping malls are connected and cooperated a lot of affiliated existing shopping malls for the cheapest price information. But, these virtual shopping mall are connected to those existing shopping mall in synchronous. So if they are connected to many existing shopping malls, we have to wait long time because of searching for many existing shopping malls. In this paper, we designed and implemented a virtual shopping mall that connect to many existing shopping malls in asynchronous. For a asynchronous communication between this virtual shopping mall and many existing shopping malls, we used JMS(Java Message Service) that is a standard Java API for MOM(Message-Oriented Middleware)

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.
