An outbreak of duck virus hepatitis was confirmed for the first time in Korea from ducklings having up to 40~65% mortality in less than 15-day-old ducklings of two farms located in the vicinity of Kwangju city. The infected ducks showed sudden death and opisthotonus position. The predominant gross lesions were found in the liver, showing enlargement and petechial or ecchymotic hemorrhages. The microscopic findings were consisted of fatty changes and necrosis of the hepatic cells, and proliferation of the bile duct epithelium. The presence of the virus was detected by electron microscopy of the sera and livers of infected ducks. The duck embryo and the ducks inoculated with the liver materials from the infected ducks showed the same lesions with those of the naturally infected ducks.

The purpose of this research is to examine residents' needs for shared community spaces and to explore the relationships between these needs and characteristics of consumers such as age and employment status of the homemakers, family life cycle stage, occupation of the primary income provider, housing size, and homeownership. Statistical data were compiled to determine frequencies and percentage distributions, and subjected to General Linear Model and Duncan-test analysis.Most residents wanted to utilize the basements of their complexes for storage space. Further interest was shown for shared community spaces that would be run by residents themselves, such as vegetable gardens, indoor playgrounds for children, senior citizen's activity rooms, walking paths, study rooms, and lounges. Female residents under 45 years old were likely to express needs for storage spaces for bicycle, and multipurpose rooms for meetings and family events. Female residents with jobs were more likely to desire shared community spaces than full-time females residents were. These findings imply the need for consideration of diverse plans rather than uniform ones. This results can be usefully applied to develop new apartment housing for different social class residents.

Various methods have been used to solve the problem of the evaluation of the complex decision-making. In the case of public projects, used the AHP method to evaluate the pre-feasibility of the projects. In this paper, The pre-feasibility was referring to the 'General guidelines for the pre-feasibility' of the KDI and was used the AHP to evaluate for public projects of the H-city. In order to achieve this object, the structured hierarchical model and questionnaire developed based on the evaluation guidelines of the KDI. Also, the weight of evaluation factor was calculated based on the AHP method and was obtained the evaluation results for the project implementation alternative.

The purpose of the study is to identify a basic spatial unit for rural village redevelopment plan. An ideal spatial unit need to satisfy three basic premises: to be homogeneous as rural community, to be appropriate to implement the project, and to be compatible with regional planning systems. A spatial unit could, empirically, be defined based on the homogeneity at first, and then appropriateness and compatibility could be used to adjust its boundary. Mitan-Myun(13 villages), Pyungchang County, Dochuck-Myun(15 villages), Kwangju County, and Chuksan-Myun(28 villages), Kimje City in Korea were selected as case study areas. The degree of interrelationship between all possible pairs in each Myun was measured using spatial, socio-cultural, and economic indicators. Multidimensional Scaling(MDS) was used to identify a homogeneous spatial unit, and then indicators representing appropriateness and compatibility were used to adjust the identified boundary. New districts which have two or three villages were suggested as a reasonable spatial unit for rural village redevelopment, and its boundary roughly overlaps with Bup-Jeong-Ri(法定里: a legally defined village).

In this study, I suggest an effective operation of waterwork facilities in large cities and a scientific method for utilizing water in water distribution systems. To achieve this goal, my simulation were carried out on data from Kwangju City using Pipenet '98, a pipe-network program. From this simulation, I examine the possibilities of application the system in large cities, comparing data measured at 33 hydraulic pressure monitoring places from waterwork enterprises. The result is coincident with that of waterwork enterprises, with about a 12.5% average error rate and $0.32kg/cm^2$ average deviation. The method and program I use here can be helpful in cities where there is a need to extend the waterwork facilities, or where there is a need to suspend the water supply, and/or there is an accident. The simulation shows how to expand waterwork facilities effectively, how to prevent accidents, and how to estimate the hydraulic pressure even in the areas without monitoring places.

Present condition of the Youngsan River pollution is serious. Concentrations of organic materials and nutrients are high and algal bloom takes place frequently. The pollution is mainly caused by domestic wastewater input from urban areas like Kwangju and Naju City. In this study, 6 times of water quality surveys were done for mainstream and tributaries. Delivery ratios of each tributaries are calculated with the water quality and flow data. With Arc/View GIS, sub-basin are divided and pollution loads are estimated. These data are used for water quality modeling. River quality improvement effects are analysed with 5 scenarios including process upgrade of present WWTPs and construction of new WWTPs. These scenarios are applied for the Youngsan River based on the 7Q10 and Q275. And total wastewater treatment cost in the basin is analysed for each scenario.

The purpose of this study is to establish a method of estimating the daily urban water demend using Backpropagation algorithm is part of ANN(Artificial Neural Network). This method will be used for the development of the efficient management and operations of the water supply facilities. The data used were the daily urban water demend, the population and weather conditions such as treperarture, precipitation, relative humidity, etc. Kwangju city was selected for the case study area. We adjusted the weights of ANN that are iterated the training data patterns. We normalized the non-stationary time series data [-1,+1] to fast converge, and choose the input patterns by statistical methods. We separated the training and checking patterns form input date patterns. The performance of ANN is compared with multiple-regression method. We discussed the representation ability the model building process and the applicability of ANN approach for the daily water demand. ANN provided the reasonable results for time series forecasting.

Recently, the tendency in the education system is toward the convergent curriculum to developing people of interdisciplinary abilities. This study was conducted to develop a clinical competence assessment program that assists health department students' clinical practice and to examine its learning effects. Study samples were composed 94 graduating student nurses who were from nursing dept of on M city. This study employed a one-group pre-post test design. knowledge, clinical competence and professional images were significantly higher in post test group. That was enhanced by clinical competence assessment program than that of the pretest group (p<.001). The results indicate that it will help students in clinical adaptability of the department of healthcare-Affiliated. Further study will be needed to identify the effect of a clinical competence and communication skills.

Management units of forest vegetation established on Mt. Moodeung (1,186.8m), a typical urban forest at Kwangju city located in the southwestern Korea, was classified phytosociologically and its spatial distribution mapped out with special reference to its ecological conservation and management. Management units of this area were classified into three categories; twenty-one higher units, ten lower units and nine lowest units, giving a total of 31 zones. Total area for detailed mapping was 2,779.5ha, of which natural vegetation accounted for 2192.0ha (78.9%), residing in most part of this area, artificial vegetation for 159.1ha (5.7%), and non-forested area including arable area, burned area and others for 428.4ha (15.5%). The ratio of natural forest element showed 93.2%, which is much higher when compared with those of other urban forests.
