As data basic to policy in nature conservation, the Degree of Green Naturality (DGN) survey was usually carried out. This also explains the impact of human interference to natural environment. Gongju gun and Yeongi gun were surveyed in the summer of 1983 to determine the DGN of these districts. Then, the surveyed DGN was compared to the existing standard. The results obtained appeared that the average DGN of these districts ranged about 5.1 to 5.9 and especially the ratio of DGN 7-graded area was high. Because of difficulties in applying the existing standard directly to middle part of Korea, further improvement on the existing standard for ranking or surveying the DGN should be reconsidered.

To examine the seroprevalence of Neospora caninum (N. caninum) infections in cattle raised at farms where an abortion had previously occurred in Gongju city and Yeongi-gun of Chungnam Province, 280 head of cattle from six farms were examined by ELISA. Thirty-two pregnant cattle from four farms were examined to determine the abortion rate in N. caninum-infected pregnant cattle and the infection pattern in newborn calves. The six farms where the abortions had previously occurred demonstrated positive reactions to N. caninum. Although the mean seropositive rate of the six farms was 17.5%, the range of seropisitivity was 3.4-57.1% due to the difference in seroprevalence between farms. The general pattern of seropositivity in cows was higher than in heifers. In addition, the abortion rate of N. caninumpositive in 18 out of 32 pregnant dams raised in four farms was 16.7%. The seroprevalence of newborn calves from N. caninum-positive pregnant animals differed according to the farm but was 86.7% overall. In contrast, 14 newborn calves from the N. caninum-negative pregnant cattle showed negative responses. This suggests that N. caninum is endemic and occurs through vertical transmission from chronically-infected dams. Therefore, aborted dams should be discarded.

Land reform in Korea was performed in 1949. The formation of owner farmers was the primary objective of land reform. But since land reform, the number of tenants has been increasing, and it reached to 65.7% of total farmhousehold by 1985. To analyze the productivity of tenant farming, 40 farmers in Kumnam, Yeongi Gun and Gongju Gun, Banpo, Chungnam Province, were selected as samples for the empirical analysis. The results of the empirical analysis are summarized as follows; 1. In plain area, tenants input 5% more labor, and 15% less capital than owner farmers. In mountain area, tenants input 15% more labor, and 4% more capital than owner farmers. 2. There is no difference in the output of rice between owner farmers and tenants in both area. 3. In plain area, the physical productivity of labor of owner farmers is 4.6 (kg/hour), and that of tenants is 4.4. And the physical productivity of labor of owner farmers in mountain area is 4.2, and that of tenants is 3.6. 4. The physical productivity of capital of owner farmers in plain area is 17.7(kg/1,000 won), and that of tenants is 20.6. In mountain area, the physical productivity of capital of owner farmers is 18.8, and that of tenants is 17.9.

There was an outbreak of food poisoning on the 17 October, 1970 among the primary school children who came from a rural area, Yeongi-gun, Choongcheongnam-do to Seoul City on an educational trip. Of the 199 children participating in the trip, 149 cases of food poisoning developed a 74.9% attack rate. The acute onset of symptoms, of abdominal pain, diarrhea, vomiting and headache which occurred 1-5 hours after eating their lunch suggests that the outbreak was due to staphylococcal food poisoning. The common source of food was identified as the lunch packed in a chip-box which were eaten on October 17 during the trip. Most probable kind of food of the lunch as the cause was the favoured fish paste. The lunch were prepared at restaurant A in Seoul City. One of the personnel of the restaurant had a unhealed cut wound on the third finger tip of the left hand, from which it was considered that the food was contaminated with Staphylococcus during preparation. The chance of multiplication of Staphylococcus to produce enterotoxin in the food might be existed during flavouring the food with some degree of heat, and also during about 10 hours elapsed before serving the food after preparation.

In this study, land cover classification and NDVI evaluation for hazard mitigation precaution are carried out in surrounding areas of Yeongi-gun, Chungcheongnam-do ($132\;km^2$) where a project for multi-functional administrative city is promoted by government. Image acquired from KOMPSAT 2, LANDSAT and ASTER is utilized and comparative evaluation on limitation in classification based on resolution was carried out. The area mainly consists of arable land including mountains, rice fields, ordinary fields, etc thus special attention was paid to the classification of rice fields and ordinary fields. For the classification of image acquired from KOMPSAT 2, segmentation technique for classification of high-resolution image was applied. To evaluate the accuracy of the classification, field investigation was conducted to examine the sample and it was compared with the land usage and classification of land category in land ledger of Korea. Acquired results were made into theme map in shape file format and it would be of great help in decision making of policy for the future-oriented development plan of multi-functional administrative city.

The water quality of the Keum river was surveyed at 4 sites from April to September in 1995 and 1997. Average values of inorganic contents analyzed in 1997 were pH 7.2, EC 0.18dS/m, $NH_4-N$ 0.60mg/l, $K^+$ 4.12mg/l, $Ca^{2+}$ 12.12 mg/l, $Mg^{2+}$ 2.75mg/l, $Na^+$ 15.1mg/l, $NO_3-N$ 1.97mg/l, $PO_4^{3-}$ 0.15mg/l, $PO_4^-$ 18.9mg/l, $Cl^-$ 21.8mg/l, Fe 0.22mg/l, COD 19.7mg/l. On the basis of these values, it was suitable for the irrigation source. Water pH of the Keum river ranged from 6.7 to 8.0. EC of the Daecheong-dam was maintained below 0.13dS/m, but those of the middle and lower stream were ranged from 0.13dS/m to 0.32dS/m. Monthly average values of all the ration contents were the highest in April and were decreased thereafter. And it was slightly increased in September. However $NO_3-N$, $SO_4^{2-}$ contents were higher in June than any other months. All the inorganic contents were the highest at Taepyeong-ri, Yeongi-gun due to sewage water and livestock wastes. The inorganic contents were negatively correlated with precipitation, generally.

The air quality modeling was carried out to assess the impact of air quality for large scale urban development. The site for the assessment is Multi-fuctional Administrative City which locates in Yeongi-gun, Chungcheongnam-do and estimated population in 2030 is 500,000. Two automatic weather monitoring stations were installed to monitor the meteorological variables for a year and upper air meteorological parameters were measured using radiosonde for 5 days with 4 hours interval in every season. The air quality of standard air pollutants were also measured for 5 days continuously in every season. The results of wind field analysis based on the site measurements and CALMET modeling showed that the valley and mountain winds were prevailed when the sypnotic wind was weak. It also showed that wind speed and directions were highly space-variable within the site basin. The variable wind characteristics implies that the Gaussian dispersion model such ISC3 and AERMOD are not appropriate and the unsteady-sate Lagrangian model such as CALPUFF is preferable. CALPUFF model was applied to assess air quality impact of new sources. The new sources were those for individual and group heating facilities as well as the traffic increases. The results showed that the estimated concentrations of CO and $SO_2$ pollutants by summing the impact concentration of new sources by the dispersion model and the ambient air concentrations by the site measurements were acceptable but those of PM-10 and $NO_2$ would violate ambient air quality standards at several locations due to high ambient air concentrations. It is recommended that the emission reductions near the site should be enforced to improve the ambient air quality.

The present study was conducted to investigate the genetic profile of two prevalent avian pathogens in Korea namely, Newcastle disease virus (NDV) and infectious bursal disease virus (IBDV). Two farms located in Yeongi-gun, Chungnam were selected for this study. The two viruses were isolated from various organs (spleen, trachea, bursa of Fabricius) of deceased chickens that showed clinical symptoms of Newcastle Disease or Infectious bursal disease like swelling and congestion of the F bursa, facial edema, lacrimation, greenish yellow diarrhea as well as pathological signs like airsacculitis, haemorrhages in the intestines and so on. For analysis of NDV and IBDV, a 466 and 435 base pair fragments corresponding to the HN and VP2 regions which are highly conserved among related strains of NDV and IBDV, respectively, were amplified by RT-PCR and analyzed by sequencing. Comparison of the VP2 region showed a $99.3\%$ homology between the Korean IBDV isolate and the BJ836-attenuated vaccine strain. In contrast, the HN region of the Korean NDV isolate only has an 83 to $84\%$ homology with the vaccine strains LaSota, B1 and VGGA. Our findings reveal that the prevalent NDV strain in Korea is genetically different from the vaccine strains and may explain the recent outbreaks of Newcastle disease in the region.
