중부지방의 중요한 수자원인 대청호의 회남교 부근에서 수화가 형성되는 시기를 전후하여 대장균군의 분포도를 조사하고, 다른 환경요인과의 상관관계를 확인하였다. 이 수역에서는 조사기간 동안 표층보다는 중층과 하층에 더 많은 대장균군이 분포하였다. 특히 수온약층이 형성되는 시기에는 중층에서 더 높은 분포도를 나타내다가 수온약층이 파괴되면서 수층간에 큰 차이 없이 거의 일정한 분포도를 보였다. 또한 강우량이 많은 시기인 6월 19일과 8월 5일에는 중층과 하층에서 대장균군의 분포도가 높게 나타났는데, 이는 유역의 오염원을 함유하고 있는 상류의 유입수가 수온약층의 하부로 흐름으로써 나타난 결과로 볼 수 있다. 또한 표층에서의 대장균군 분포도는 시안세균에 의한 수화가 형성되는 시기에 비하여 다른 시기에 비교적 높게 나타났는데, 이는 시안세균의 높은 광합성 결과로 표층의 pH가 높아짐으로써 대장균군의 생장이 억제된 결과로 이해할 수 있다. 이상의 결과로부터 자연수계의 대장균군은 외부에서 유입되는 것이 대부분이며, 시안세균의 활성이 높은 시기에는 그 분포도가 낮아진다는 것을 알 수 있다. 이러한 점에서 수화와 같이 환경의 변화가 심한 시기에 자연수계의 분변오염 여부를 대장균군의 분포도만으로 예측하는 것은 한계가 있다고 하겠다. The authors surveyed the monthly variations of distribution of coliform bacteria in Daechung Dam reservoir during cyanobacterial water bloom, and examined its relationship with environmental factors. The distribution of coliform bacteria was higher at middle and bottom layer than at surface layer. Especially its distribution at middle layer was high during the period of thermal decline, and showed little difference in population size of coliform bacteria when thermal decline destroyed. At June 18 and August 5, the period of higher rainfall, the coliform bacteria distributed highly at middle and bottom layers, which seemed to be the result of inflow of low-temperature water. At surface layer, coliform bacterial distribution was higher during water-bloom period, which can be explained by the result of higher pH of surface water resulted from strong photosynthetic activity. These results show that the coliform bacteria in natural water ecosystem originate from the inflow of water and its distribution is low during the period when cyanobacteria grow actively. This suggests that it have a problem to estimate whether the natural water is contaminated with feces.

The authors surveyed the present situation of Agaricus sp cultivation and its disease occurence in Western Kyong-Nam area. 192 farmers, which is 66% of the mushroom-cultivating farmers, were growing Agaricus sp. Especially there were 124 farms in Western Kyong-Nam around Chinju-City. The greater part of mushroom-farmers cultivated Agaricus sp. on tables using cotton as major medium. And they purchased the eldest mycelium from other districts. About 60% of the farmers were suffering some losses due to the development of disease. The major disease seemed to be brown blotch. When a mushroom-disease has developed, most farmer coped with it by removing the cotton media, and sometimes by treating with chemicals. Mushrooms seemed to be a major source of farmers' income, and some govenmental and scientific supports are needed for the development of mushroom cultivation.

The capability to map all potrions of the earth's surface always depended on the capacity to survey. Classical analog photogrammetry has been enhanced by more accurate and more rapid digital vector output. Analog plotter can moreover now easily be converted into analytical instruments to facilitate orientation, operator asisted DTM measurement, aerial triangulation, and vector plotting. Digital photogrammetry with scanned aerial photography has greatly enhanced the capabilities of restitution at large and medium scales. Digital orthophotography offers possibilities, which are one order of magnnitude less costly than conventional mapping, even though the same resolution performance cannot yet be reached, when digital work stations with reasonable computing speeds are campared with analytical plotters. However with rapidly increasing computer performance, the situation is gradually changing in favour of digital systems. In this study, the accuracy of three dimensional location was improved by bundle block adjustment with additional parameters, which are able to systematic error through detection and elimination of the gross error for observation values in aerial triangulation. In order to test thevariability in performance of the different weighting schemes in accurately detecting gross error, robust estimation method. And also, the different control point patterns and ovelap, twelve types of additional parameters were used for comparison analysis. As a result, it is expected to the sequential procedure of analysis can be utilized in the accuracy analysis of aerial triangulation effectively.

유리인산 생산균을 생물비료화 하기 위한 노력의 일환으로 인산가용화능이 우수한 Aspergillus sp. PS-104 균주를 액침배양하면서 pellet 형성에 미치는 황토의 영향을 조사하였다. Aspergillussp. PS-104의 분생포자를 황토를 포함하는 PDB 배지에 접종하여50 rpm의 낮은 속도로 교반하여 배양하면 무정형의 불규칙적인pellet을 형성하는 반면에 150 rpm의 높은 속도로 배양하면 구형의 규칙적인 pellet을 형성하였다. 또한 0∼10% (W/V) 범위의황토 첨가시에는 황토의 농도가 높을수록 pellet의 크기가 작게 형성되었으며, 1.0% 황토 농도에서 1.0±0.1 mm의 가장 작은pellet이 형성되었다. 이 결과는 황토를 첨가하지 않는 경우에 비하여 약 4배 작아진 것이다. 그러나 황토 농도가 1.5% 이상 되면 무정형의 큰 pellet이 형성되었다. 또한 황토의 주성분인 SiO_2Fe_2O_3, A1_20_3, CaC0_3, Caso_4,MgC0_3 분말을 각각 O∼l.0% 농도로 배지에 첨가하여 pellet 형성에 미치는 영향을 조사한 결과Al_2O_3를 제외하고는 첨가물의 농도가 높을수록 작은 크기의pellet이 형성되었으며, MgCO_3를 첨가했을 때 가장 작은 크기의pellet을 형성하였다. In order to investigate effects of loess on the mycellial pellet formation a phosphate-solubilizing fungus Aspergillus sp. PS-104 was cultured in potato dextrose broth containing loess. The strain formed an amorphous pellet or loose aggregates agitated at a low speed (50 rpm) while spherical and regular pellets at a high speed (150 rpm). The higher concentration of loess was added, the smaller size of a pellet was formed during the submerged culture of the strain. As shown in results, being cultured in the PDB medium supplemented with 1.0% loess the pellet size was maximally reduced to a fourth compared to the control. Evaluating the addition effect of several components of loess such as SiO_2, Fe_2O_3, Al_2O_3, CaCO_3, CaSO_4 and MgCO_3 on the reduction of mycellial pellet size the higher concentration was supplied, the smaller size of pellet was formed except Al_2O_3 And the smallest pellet size was recorded at the concentration of 1.0% (W/V) magnesium carbonate.

The author examined microbiological water quality in Chinju National University. Water temperature was lowest at site 1 as 9.45℃, and highest at site 7 as 26.11℃ on average. pH was neutral being in the range of pH 6.28∼7.75. There was a little relationship between sampling sites and sampling time. General bacterial number exceeded the standard of water quality in every sites. And not a few bacteria were detected in the purified water. Coliform bacteria were detected at every sites and the number increased after rainfall. These results suggest that the water quality should be appropriately managed, although the present microbiological water qualigy is not so serious a problem.
