In order to monitor the parasites 426 fecal samples were taken from deer in Chonbuk area. The identification of the parasites was determined by the fecal examination using the floatation and microscopical examination, respectively. The results were summarized as follows; The detection rate of the parasites was 23.2%. Mixed infection rate was single 20.3% (87 heads), double 2.6% (11 heads), triple 0.2% (1 heads), respectively. The parasites isolates were identified as heamonchus spp from 40 heads, eimeria spp from 24 heads, trichoetrongyius spp from 13 heads, capiliaria spp from 9 heads, parapsitomum spp from 8 heads, strongyloides papillosus from 1 head, diotyocaiius fiiaria from 1 head.

To investigate the swine parasitic infection rate, we performed centrifugal floatation method and sedimentation method between Jan. 1989. and Dec. 1989. This results are shown as follows. 1. The numbers of infection were 593 pigs in 1080, shown 54.9% of infection rate. 2. In this survey, eight species of swine parasite were detected. The percentage of Balantidium coli was 44.5, revealed hightest level. There were 14.5% in Ascaris suum and 11.8% in Oesophagostomum SP respectively. 3. In this survey, there was high rate(86.0%) of parasitic infection in the pig raised at sawdust fermantation house. This results suggest that pig maybe liable to infect parasite.

Preserving reservoir safety has recognized to be important for the public where a vast majority of dams are located upstream of greatly populated cities and industrialized areas. Buckling, floatation and cavitation have caused failure in the spillway gates and conveyance features during past catastrophic events; showed their vulnerability and need for regular inspection along with reviewing design calculations to ensure the spillway meet current design standards. This paper investigates the hydraulic and structural consideration of dam's spillway by evaluating the data of Karkheh Dam's. Discharge capacity, flood routings and cavitation damage risk were main features for hydraulic considerations where hydrostatic and hydrodynamic forces and stability conditions were considered in structural considerations.

We are currently conducting studies on culturing and biocompatibility assessment of various cells such as neural stem cells and induced pluripotent stem cells(IPS cells) on carbon nanotube (CNT), on nerve regeneration electrodes, and on silicon wafers with a focus on developing nerve integrated CNT based bio devices for interfacing with living organisms, in order to develop brain-machine interfaces (BMI). In addition, we are carried out the chemical modification of carbon nanotube (mainly SWCNTs)-based bio-nanosensors by the plasma ion irradiation (plasma activation) method, and provide a characteristic evaluation of a bio-nanosensor using bovine serum albumin (BSA)/anti-BSA binding and oligonucleotide hybridization. On the other hand, the researches in the case of "novel plasma" have been widely conducted in the fields of chemistry, solid physics, and nanomaterial science. From the above-mentioned background, we are conducting basic experiments on direct irradiation of body tissues and cells using a micro-spot atmospheric pressure plasma source. The device is a coaxial structure having a tungsten wire installed inside a glass capillary, and a grounded ring electrode wrapped on the outside. The conditions of plasma generation are as follows: applied voltage: 5-9 kV, frequency: 1-3 kHz, helium (He) gas flow: 1-1.5 L/min, and plasma irradiation time: 1-300 sec. The experiment was conducted by preparing a culture medium containing mouse fibroblasts (NIH3T3) on a culture dish. A culture dish irradiated with plasma was introduced into a $CO_2$-incubator. The small animals used in the experiment involving plasma irradiation into living tissue were rat, rabbit, and pick and are deeply anesthetized with the gas anesthesia. According to the dependency of cell numbers against the plasma irradiation time, when only He gas was flowed, the growth of cells was inhibited as the floatation of cells caused by gas agitation inside the culture was promoted. On the other hand, there was no floatation of cells and healthy growth was observed when plasma was irradiated. Furthermore, in an experiment testing the effects of plasma irradiation on rats that were artificially given burn wounds, no evidence of electric shock injuries was found in the irradiated areas. In fact, the observed evidence of healing and improvements of the burn wounds suggested the presence of healing effects due to the growth factors in the tissues. Therefore, it appears that the interaction due to ion/radicalcollisions causes a substantial effect on the proliferation of growth factors such as epidermal growth factor (EGF), nerve growth factor (NGF), and transforming growth factor (TGF) that are present in the cells.

Fecal samples were taken from 402 cows in Posung, Chonnam where was designated as a place for Korean native cattle breeding. Prevalence of internal parasitisms were determined by the fecal examinations using the floatation and sedimentation procedures. 62.9% of the cows were found as positive cases with excretion of the eggs of Fasciola hepatica in the fecal specimens. Of those infected with F hepatica 97 cows free of other pathogenic intestinal parasites were chosen for albendazole treatment. Albendazole tablets(10mg/kg) were administered to the cows twice at the interval of 4 weeks. Blood samples were collected via jugular vein prior to the first treatment, four weeks after the first treatment and four weeks after the second treatment, respectively. At the same time fecal samples were collected for parasitological examinations by sedimentation methods. The mean pretreatment count was 44 fluke eggs per gram of feces, which compared with 27 epg and 17 epg four weeks after the first and second treatment, respectively. Most of the hematological and biochemical values fluctuated within the normal ranges during the experiment. Eosinophil counts were high initially, decreased after the first treatment and thereafter remained steady. The opposite was the case with aspartate and alanine aminotransferases.

The Republic of Korea (South) and the Peaples Republic of Korea (North) had agreed to exploit the North Korean rich natural resources starting from the year of 2006. Through this mutual agreement DPRK shall quarantee ROK's investment in the North Korean Mines and supply mineral products for the compasation of the financial investment supported by ROK. In the area of northern part of Korea, many kind of natural resources such as Magnesite, Iron, Gold & Silver, Copper, Lead & Zinc, and Coal are plentifully deposited. In the area of southern part of Korea, however, most kind of natural resources have been exhausted and so presently major minerals such as Gold & Silver, Copper, Lead & Zinc and Coal are being imported and relying on foreign countries in whole quantity of the requirement. On the other hand Northern Part of Korea is making very slow progress in mining and exploitation owing to the lack of investment even though there are rich deposits of natural resources. And in Southern Part of Korea, they have most advanced production facilities and technologies in the world in the fields of Mineral Floatation, Steel Manufacturing, Nonferrous Metal Smelting & Refining and those plants fabrications. A combination of Southern Technologies together with Financial Support and Northern rich natural resources & Labour Power will be a most hopeful, desirable and mutually required 'South-North economic Cooperation' as the mining industries are labour intensive.
