신장이식은 환자의 삶의 질을 높이고 거의 정상적인 사회생활을 가능하게 함으로써 말기신부전 환자의 3가지 신대체 요법(혈액투석, 복막투석, 신장이식) 중에 가장 효과적이고 각광받는 치료법이라 할 수 있다. 최근 들어 의료기술과 의학의 발달로 신장이식의 성공률은 과거에 비해 비약적으로 높아지고 있으며 국내에서도 점차 신장이식수술을 받는 환자가 증가하고 있으나 서울이나 다른 대도시에 비해 의료환경이 열악한 중소도시나 지방의 병원에서는 아직도 시행하지 못하고 있는 형편이다. 이에 저자들은 경북 최초로 자체 의료진에 의해 고혈압과 말기 신부전으로 동국대 포항병원에서 혈액투석을 받고 있던 32세의 남자환자에게 부인으로부터 신장을 제공받아 신장이식을 성공적으로 시행하였기에 문헌고찰과 함께 보고하고자 한다. Kidney transplantation is the preferred treatment modality for many patients with end-stage renal disease (ESRD), because it offers improved quality of life over both hemodialysis and peritoneal dialysis. Patients who do well after transplantation generally report improvement in vitality and freedom to return to the style of life that they experienced before their progression to ESRD. Recently, the success rate of kidney transplantation is greatly being increased as the surgical technique and immunosuppressive drugs are developed. Kidney transplantation is also popular in Korea which has good result. But, until now the general hospitals which are located at small city can't try the kidney transplantation because they don't have proper facilities and experts. We firstly experienced a case of kidney transplantation in a 32 years old man with hypertension and chronic renal failure at KyoungBuk province. So we report this case with references.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Background Development of genetically modified crops has rapidly increased in last few years. The most widely grown GM crops express genes that confer herbicide tolerance and insect resistance. Detection system of GM crops is important for safety evaluation before its consumption. Objective The purpose of this research is to detect GM crops, especially PAT, in food-samples. Results The bar gene (PAT protein, herbicide resistant) was cloned in pGEX-4T-1 and expressed by E. coli. The high-affinity PAT-specific single-stranded DNA (ssDNA) aptamers were obtained from a random DNA library. MOE docking study was performed to identify the potential binding region of the selected aptamers on PAT. Aptamer-linked immobilized sorbent assay (ALISA) method was used to detect PAT. Conclusion We screened aptamer against PAT for developing an efficient detection method. The selected PAT specific aptamers, HRPA-05 and HRPA-07, showed the distinct target binding behaviors, and detected PAT protein by aptamer-linked immobilized sorbent assay method with high efficiency and selectivity.

EU의 Biomass를 이용한 에너지 생산

이종식,고문환,박우균,안종웅 한국국제농업개발학회 2003 韓國國際農業開發學會誌 Vol.15 No.3

EU 국가들의 1993년부터 1999년까지의 6년간 재생에너지 사용량 변화를 살펴보기 위하여 절대량 증가와 증가율을 조사하였다. 많은 나라들이 높은 사용량 증가 또는 증가율을 나타내었다. 초기에 재생에너지 사용이 적었던 나라들은 1999년에도 실질적인 생산량은 적지만 기간 중 높은 증가율을 보였다. 반면에 1993년에 이미 사용량이 높았던 나라들은 낮은 증가율을 보였으나 전체사용량은 높은 수준이었다. 재생 에너지 사용의 성공 여부는 보급 확대를 위해 많은 장해물들을 극복한 후에 성취될 수 있다. 보급 확대를 위한 요인들로는 정치적, 제도적, 재정적, 행정적인 지원과 기술개발, 홍보, 교육 및 훈련 등이 있다. Biomass를 이용한 에너지 생산 및 보급에 성공한 덴마크, 핀란드, 독일, 스페인 및 스웨덴의 송공 요인들을 소개하였다. In order to identify those Member State/technology combinations where there has been most success in achieving renewable energy penetration over the six-year period 1993-1999, the two selection criteria such as absolute increase and percentage of increase have been applied. Many Member States show either a large absolute increase in renewable energy output, or a large percentage of increase. Member States with only very low initial levels of renewable energy use may demonstrate rapid growth rates even though the actual quantity of output is still only small. Conversely, Member State with levels of renewable energy use that were already relatively high in 1993 show a less rapid percentage growth rate, but these Member States may still Have added significant quantities to the overall output. Successful penetration of renewable energy can only be achieved after overcoming many varied obstacles to an increase in their exploitation. Factors, which can influence the successful implementation of renewable energy projects, include political, legislative, financial administration, technological development, information, education and training. Examples of successful penetration of biomass power were shown for Denmark, Finland, Germany, Spain and Sweden.

본 논문은 아스팔트 혼합물의 소성변형 저항성과 상관성이 높은 특성치를 찾고자 Kim test를 개발하여 현재 적용성 연구결과를 다루고 있다. 이 논문은 새로운 강도특성치인 변형강도(S_(D))를 개발하는 Kim, test 연구의 4단계 연구 결과이다. 13 mm 골재(편마암, 화강암)와 입도(밀입도, 갭입도) 5가지 폴리머로 제조한 8가지 바인더로 두 가지 입도에서 소성변형 저항성이 다른 32가지 혼합물을 만들었다. 슬래브(305㎜×305㎜×62㎜)공시체를 제조하여 한쪽은 Kim, test를 수행하기 위하여 18 cm정도로 잘라서 코어를 3개 채취하고 다른 한쪽은 12cm크기로 하여 반복주행시험을 실시하였다. Kim, test는 하중봉 3(0.75), 4(1.0)을 사용하였다. W/T시험으로부터 최종 침하 깊이와 동적안정도의 두 가지 소성변형 계수를 각 혼합물별로 구했다. 각 하중봉과 골재별, 입도별로 S_(D)와 소성변형 계수간의 통계적 상관관계 분석을 수행한 결과 S_(D)와 소성변형 계수와의 결정계수가 매우 높게 (R²>0.95) 나타났다. 하중봉 4(1.0)이 3(0.75)보다 다소 높은 상관성을 보였다. 향후 Kim test실험에서 하중봉 4(1.0)을 사용하고 4단계 방법을 이용한다면 소성변형 특성치인 침하깊이(DR)와 동적안정도(DS)와의 상관성이 매우 큰 시험법이 될 것이다. 또한 변형강도의 파괴 메커니즘은 콘크리트의 펀칭파괴와 유사하여 콘크리트의 전단강도 추정식을 근거로 아스팔트 콘크리트의 재료 특성에 적합한 추정식 계수 ◁ 원문 수식 참조 ▷ 를 얻었다. 이 식을 이용한다면 아스팔트 콘크리트가 견딜 수 있는 임계하중을 변형강도에 근거하여 추정할 수 있을 것이다. This study shows predictability of rut parameters of modified and unmodified asphalt concretes based on the deformation strength (S_(D)) which is calculated from the maximum load, deformation and size variables of loading head under simple static loading. This paper is the result of latest studies, phase 4 which is a part of Kim, Test studies for developing a new strength property for asphalt concrete. Two aggregates, gneiss and granite, two gradations, dense-graded, gap-graded, with maximum, size of 13mm and eight binders using different contents of five polymers (RLDPE, RHDPE, LDPE, SBS, SBR) were used to produce 32 different mixtures. A slab (305㎜×305㎜×62㎜) was cut into two pieces(18cm and 12cm width) and three 10cm cores were taken for S_(D) test from the larger piece and wheel tracking test was performed on the smaller piece. Kim test was performed using loading head 4(1.0), 3(0.75). Two rut parameters, depth of rut and dynamic stability, from the rut depth-cycle curve from a WT test were obtained for each mixture. Statistical analysis were performed for each loading head, aggregate, and gradation to find out correlation between S_(D) values and each rut parameter. The analysis results showed that S_(D) had high R² (over 0.95) on the average with rut parameters. The loading head 4(1.0) showed R² better than 3(0.75). It is concluded that S_(D) is the property that has excellent predictability for rut parameter of asphalt concretes. An equation, ◁ 원문 수식 참조 ▷ was obtained based on the equation of concrete shear load creating punching failure and current test data, because the failure mechanism of S_(D) is similar to punching failure of concrete. In the equation, P is shearing force creating punching effect, b is length of perimeter of punching area and d is depth of specimen. If this formula is used, a critical load for deformation failure will be predicted based on the S_(D).

The purpose of this study is intended for effective recycling of waste concrete. It analyzes the quality 0 the recycled coarse aggregate with production types. The conclusions of the study are as follows. 1. The recycled coarse aggregate which is produced through 5th Crushing Process (A-Type) shows the improvement in grading and particle shape, reduction in an absorption rate until 1.14% due to removal of attached the mortar and paste. Therefore, it satisfies the standards of KS F 2573(recycled aggregate for concrete) as the first grade. 2. The recycled coarse aggregate which is produced through 3rd Crushing Process(B-Type) is suited to the quality prOVlSlOns of the standards of KS F 2573, shows a 3.12% absorption rate that is second grade as recycled coarse aggregate. Based on the above results, it is possible to product first and second grade recycled coarse aggregates with production types. It is concluded that recycled coarse aggregate with production types can be used as aggregate within required conditions. And more researches are also needed to make recycled coarse aggregate better to use for concrete.
