A series of laboratory experiments were carried out to find the effects of soil organic matter contents, soil temperature, pH values, kinds and amount of nitrogen fertilizers on the denitrification-$N_2O$ gas evolution-. The results obtained were summarized as follows: 1. Denitrification rate, amount of $N_2O$ gas evolution, was influenced the order of organic matter contents>soil temperature>pH values>kinds of N-fertilizer>levels of N-fertilizer. 2. The highest dentrification rate was observed in organic matter content of 3.0%, pH values at 6.0 with application of $KNO_3$ at levels of 20 mgN/100g soil. 3. For the evolution of I mole $N_2O$ gas, averaged carbon consumption was obtained as 0.5 mole in all these experiment condition. However, the highest carbon consumption rate was obtained in organic matter contents for 1.0% with application of $(NH_4)_2SO_4$ at levels of 10 mgN/100g soil (1.06 mole) while lowest carbon consumption rate was obtained in organic matter contents for 3.0% with application of $KNO_3$ at levels of 20 mgN/100g soil (0.13 mole). 4.

The results obtained was as 550 ug for $(NH_2)_2CO$ and 1100 ug $N_2O/100g$ soil by application of $KNO_3$ in organic matter contents of 1.0% soil. On the other hand, when the application $(NH_4)_2SO_4$ the V/2 values of $N_2O$ gas was obtained as the amount of 490 ug/100g soil while V/2 values of $N_2O$ gas by application of $KNO_3$ was on the linear line in soil organic matter contents of 3.0%.

This paper presents the geophysical applications to the environmenml problem in an abandoned mine area. We would like to focus our attention on the mapping of the soil contamination and the detection of the buried mine tailings. For mapping the soil contamination. measurements of both in-situ magnetic susceptibility (k) and terrain conductivity were carried out. In-situ magnetic susceptibilities of the contaminated soil due to the acid mine drainage show higher values than those of the uncontaminated area. However. those data do not show the correlation with the degree of the soil contamination observed on the surface. The least-squares fitted formula obtained with the measured insitu magnetic susceptibilities is $k=4.8207{\times}W^{0.6332}$, where W is the $Fe^{+2}$ weight percentage. This weight gives most effect to magnetic susceptibility of the soil. Lateral variations of the soil contamination in the shallow subsurface can be detected by the electrical conductivity distributions from EM induction survey. TDIP (Time Domain Induced Polarization) and EM induction surveys were conducted to detect the buried mine tailings. From the results of TDIP, the spatial zone, which shows high chargeability-low resistivity, is interpreted as the buried mine tailings. Therefore, it is concluded that it is possible to discriminate the spatial zone from the uncontaminated ground.

A laboratory experiment was conducted to find out the number of soil microorganisms, identification and enumeration of soil microbial species on the mineral and volcanic ash soil with different cropping system of the Jeju Island. The results obtained were summarized as follows: 1. The number of bacteria was high in mineral soil with rotation of upland crops than that of volcanic ash soil with continuous cropping system. 2. According to identification of soil bacteria, the most of bacteria were composed to short rod with Gram negative. Among the bacteria species, Rhizobium spp. and Flavobacterium spp. were most high population in both of mineral and volcanic ash soil. 3. The number of fungi in mineral soils were reduced by the rotated cultivation of upland crops but no significant differences were observed in volcanic ash soil with continuous cropping system. On the other hand, Aspergillus spp., Fusarium spp., and Penicillium spp. were most high population in both of mineral and volcanic ash soil. 4. Comparing of the number and species ot microorganism to the cash crops soil in main land, about 10 to 100 times for bacteria and more than two times for the number and species of fungi were lowered in Jeju Island soil.

이상규,백남호,Sang Kyu Lee,Nam Ho Baek 대한안과학회 2009 대한안과학회지 Vol.50 No.1

Purpose: We evaluated the short and long-term changes of intraocular pressure (IOP) and studied its risk factors in pseudoexfoliation (PEX). Methods: A total of 40 eyes that had been newly diagnosed with PEX from January 1, 1995 to December 31, 2007 were included in this study. Age, gender and accompanying systemic disease were recorded. In addition, the age, gender, number of antiglaucoma eye drops, history of cataract operation, and history of systemic disease were evaluated as risk factors for IOP elevation during the follow-up periods. Pre and post cataract operation IOP was checked to evaluate the effect of the cataract operation on IOP. Results: The risk factors for IOP elevation in patients newly diagnosed with PEX were old age and female gender. After treatment, a long follow-up period and number of eyedrops were risk factors for IOP elevation. The cataract operation had a one year IOP control effect, especially in cases where the pre operative IOP was greater than 21 mmHg. Over the long term, however, the IOP control effect of cataract surgery could not be determined. Conclusions: IOP increased as result of increased patient age. Phacoemulsification was a protective factor for IOP elevation and may be a good method for short-term IOP control.

Mesenteric and omental cysts are rare lesions in childhood. These cysts are morphologically and pathologically similar to lymphangiomas that occur in other parts of the body. From 1980 to 1997, 8 children were diagnosed and treated for mesenteric or omental cysts. Their ages ranged from 18 days to 6 years. There were 5 boys and 3 girls. The main presenting symptom was abdominal pain. Operative procedures were complete cysts excision, complete excision with intestinal resection, or complete excision with intestinal resection and colostomy. Accurate preoperative diagnosis was possible with the current ultrasonographic imaging techniques. Complete excision of the lesion was possible in all patients and results were excellent.

The aerobic heterotrophic bacteria in the histosphere associated with grasses (Gramineae, Caryphyllaceae, Crucifereae) and rice cultivars in saline and reclaimed saline paddy soils were varied with species and rice cultivars. The fraction of aerobic heterotrophic $N_2$-fixing bacteria to the total aerobic heterotrophic bacteria were averaged to eighteen percent in the histosphere of grasses and rice. Acetylene reducing activity of these bacteria were ranged from 1 to 24 n mole/tube/hr. Most of the bacteria strains were predominated of hydrogen utilizing bacteria. The majority of these bacteria were closed to Pseudomonas, Azospirillum, Klebsiella and Agrobacter.

이상규,박동원,장수일,Lee, Sang-Kyu,Park, Dong-Weon,Chang, Soo-Il 대한소아외과학회 1998 소아외과 Vol.4 No.1

신생아 및 영아에서의 횡격막 이완증은 일반적으로 드문 질환으로 인식되어 있지만 이에 대한 정확한 진단과 적절한 원인별 처치의 필요성은 널리 알려진 사실이다. 최근 저자 등은 5 례의 선천성 횡격막 이완증을 경험할 수 있었고, 전 례 모두 수술이 적응되었다. 전 례 모두 생후 2개월 미만의 영아였고 모두 남아였다. 이완 부위는 전 예에서 좌측 횡격막이었다. 증상은 3례에서 호흡기 증상이 있었고 소화기계 증상은 없었으며 나머지 1례에서는 체중 증가불능 이 외는 무증상이었다. 전 예에서 방사선학적 변화가 저명하였고, 횡격막의 절정은 제 3에서 제 5늑간에 달하였다. 수술 술기로 저자 등은 경복부 접근 방법에 의한 횡격막 습벽 봉합술을 선호하였으며 수술 결과는 임상적으로나 방사선학적으로 우수하였다. Although diaphragmatic eventration in newborn infants is generally regarded as a rare condition, the need for accurate diagnosis and appropriate intervention according to the etiological factors is well known. Recently the authors experienced five consecutive cases of diaphragmatic eventration below the age of two months(one to 55 days) requiring surgery. All were in males, and were left sided. Respiratory symptoms were present in 4 patients, and one patient showed inability to gain weight. Diaphragms were elevated to the level of the third to fifth intercostal spaces. Diaphragmatic plication through the abdomen gave excellent results. There was no postoperative mortality.
