기종성 신우신염은 주로 당뇨병환자나 폐쇄성 요로질환을 가진 환자에 발생하며 특징적으로 신실질 및 그 주위조직에 가스를 형성하면서 심한 조직괴사를 일으키는 매우 드문 급성 화농성 신감염으로 사망률이 높은 질환이다. 이 질환은 1989년 Kelly와 MacCallum에 의해 처음 보고된 이래 외국문헌에 약 90례 정도가 보고되어 있으며 국내에는 28례가 보고되어 있다. 수액 및 전해질 보충, 인슐린 투여를 통한 적절한 혈당조절 및 항생제 투여등의 내과적 치료와 절개배농 및 신적출술등의 수술적 치료 방법이 있다. 내과적 치료로 가스의 감소가 없는 경우에는 즉각적인 수술적 치료를 시행하여야하므로 이 가스변화에 대한 추적관찰이 중요하다 하겠다. 본 저자들은 당뇨병환자에서 발생한 기종성 신우신염 1례를 내과적 요법을 치험하였기에 문헌고찰과 함께 보고하고자 한다. Emphysematous pyelonephritis is rare, life-threatening infection of the renal parenchyma and perirenal tisseue. This disease is characterized by the production of intrarenal and perirenal gas and is frequently encountered in patients with diabetes mellitus or urinary obstruction. We experienced a case of emphysematouse pyelonephritis in a 62 years old women with poorly controlled diabetes mellitus who had been managed with medical theraphy. So we report this case with a review of the referenced literatures.

Objective: The purpose of this study is to compare the effects of Dong-si acupuncture therapy and General acupuncture therapy for the patients with acute ankle sprain. Methods : This study has been carried out for 60 cases of ankle sprain patients who have visited Dong-Seo Oriental medical Hospital from May 1, 2002 to September 30, 2002. We have treated 30 cases of them by Dong-si acupuncture therapy and the other 30 cases by General acupuncture therapy. And we have compared those two group. Results : 1. There was no significant difference at the treatment period and the number of treatment times in comparing two groups. 2. The number of treatment times for good effect is that : Dong-si took $1.57{\pm}0.85$ times and General acupuncture therapy took $2.15{\pm}0.96$ times. And we have found that the effect of Dong-si acupuncture therapy is faster than the other.

In short is as follows to research the present situation and mooted point, to get ready development direction of horticulture equipment in Busan. 1.Area of culture equipment in Busan is that vegetables was formed 1.7% for 435ha of nationwide 82,465ha, florist crops was formed 6.7% for 220ha of nationwide 3,299.2ha in standard of 1998. 2.In the present situation of equipment of vegetable culture, fruit vegetables are a lot more in culture area and productive quantity. There is mainly cultivated tomato, cucumber and unripe red pepper. 3.In the present position of equipment of florist crops area, cut flower is formed 76.8% as 169ha in nationwide florist crops area. There is mainly cultivated carnation, rose, gladiolus. 4.In the usual present position of frame materials in equipment, vegetables equipment is built at 82.5% with iron frames. But iron frames is far the lower rate as 22.6% than 87.1% of nation rate in florist crops. It should be converted to iron frames for the durability and efficiency management of environment. 5.In the usual present situation of covering material in equipment, it is in use soft film as 97.8% and have the lots use of PE, EVA film. 6.In the present position of environment management of equipment, as 88% used soft film which is habitual means, Heat culture is used warm-air heater around 95%. In overhead non-woven fabric. Heat culture is used warm-air heater around 95%. In overhead flooding of equipment, the overhead flooding used hose is a lot most as 50.1%, it its increased the farmhouse which use sprinkler or dripping flooding materials, also. 7.The system of equipment is movable style is 55%, fixed style is 45%. the type is the single span is many more as 73.5% than 26.5% of multi span. The direction is, in case of single span is east and west, in case of multi span is mainly south and north. 8.The nutriculture area is took vegetables were 4.7ha and florist crops were 3ha. In the case of florist crops, rose was 4.3ha and eggplant was 0.3ha. In the case of florist crops, rose was 3ha by crops. In has to consider a special countermeasure in application and supply of farmhouse used the equipment in Busan because Busan was fell behind than other city in nutriculture area and culture technique. 9.In the export of horticulture equipment crops, vegetables are tomato, cucumber, florist crops are rose, chrysanthemum and europeans orchid but the work has not yet born fruit. It must be solve mooted point of low grade article, lack information. etc. So it is brought up the export horticulture.

This paper presents a new economic dispatch algorithm to improve the unit commitment solution while guaranteeing the near optimal solution without reducing calculation speed. The conventional economic dispatch algorithms have the problem that it is not applicable to the unit commitment formulation due to the frequent on/off state changes of units during the unit commitment calculation. Therefore, piecewise linear iterative method have generally been used for economic dispatch algorithm for unit commitment. In that method, the approximation of the generator cost function makes it hard to obtain the optimal economic dispatch solution. In this case, the solution can be improved by introducing a inverse of the incremental cost function. The proposed method is tested with sample system. The results are compared with the conventional piecewise linear iterative method. It is shown that the proposed algorithm yields more accurate and economical solution without calculation speed reduction.

The purpose of this study was to find out blood lead and cadmium concentration levels of rural residents. The blood samples were collected from 140 rural residents in 5 nonpolluted regions in Kunbuk-Myun, Kumsan-Gun, Chungnam province from August 31 to September 30, 1990 and analyzed by atomic absorption spectrophotometry. The results were summerized as follow : The mean concentration level(range) of blood lead was 0.240±0.060㎍/ml(0.130-0.390㎍/ml) for males and 0.237±0.056㎍ /ml(0.120-0.370㎍/m) for females. There was no statistically significant difference among age groups and sexes. The distributions were similar to normal distribution in both sexes. The mean concentration level(range) of blood cadmium was 0.066±0.099㎍/ml(0.012-0.582㎍/ ml) for males and 0.060±0.062㎍/ml(0.015-0.392㎍/ml) for females. There was no statistically significant difference among age groups and sexes. The distributions were skewed to the low level ranges in both sexes. The lead concentration level in whole blood did not show statistically sinificant difference among kinds of farming product. But the cadmium level of the rice-ginseng-tobacco farmers was statistically significantly high (p<0.005). The cadmium concentration level in whole blood was 0.040±0.027㎍/ml for the rice-ginseng farmers, 0.076±0.100㎍/ml ofr the rice-tobacco famers, and 0.158±0.171㎍/ ml for the rice-ginseng-to-bacco farmers. There were no statistically significant difference in blood lead and cadmuim concentration levels among groups classified by drinking habit, smoking habit and exposed years to pesticides. The correlation coefficent between the blood lead and cadmium concentration levels was statistically significant(R=0.2054, P<0.05).

The stability constant, enthalpy, and etropy changes of complexation of heavy metal ions (Zn²*, Cd²*) with podands containing nitrogen-sulfur donors such as tri(phenylthio-2-ethyl)amine (Podand Ⅰ), tri(benzylmercapto-2-ethyl)amine(Podand Ⅱ), and tetra(phenylthio-2-ethyl)ethylenediamine (Podand Ⅲ) have been determined by using potentiometric titration in 95% MeOH at various temperature. We observed the Podand Ⅲ ligand showed the largest protonation constant. The values of protonation constant and stability constant for Zn(Ⅱ), and Cd(Ⅱ) ions among three different ligands were increased as following order, Podand Ⅰ< Podand Ⅱ< Podand Ⅲ. In addition, thermodynamic parameters ΔH and TΔS of Zn(Ⅱ), Cd(Ⅱ) complexes have studied.

The process and size effects on the fracture strength of single-crystal Si were evaluated using a microtensile testing method. The microtensile specimens of single-crystal Si films were fabricated by CMP(chemical-mechanical polishing) and micromachining processes, The microtensile test setup was built to accommodate requirements such as specimen handling, jig, alignment and very small loads and displacements. The variations in the fracture strength with thickness and effective volume of the Si film were evaluated. In addition, the results were discussed statistically. The effects of dry-etched surface and CMP surface on the mean fracture strength were compared. Through AFM (atomic force microscopy) observation, it could be found that the larger flaws of the dry-etched surface affected significantly on the decreasing of the mean fracture strength.
