전라북도 장안산의 72군락 지점에서 식물사회학적 조사에 의하여 구분된 10개 군락. 즉 신갈나무 군락, 신갈나무-철쭉꽃 군락, 신갈나무-노린재나무 군락, 신갈나무-졸참나무 군락, 졸참나무 군락, 굴참나무 군락, 서어나무 군락, 물푸레나무 군락, 층층나무 군락, 들메나무 군락에서 풍부도지수, 이질성지수, 균등도지수, 우점도지수를 산출하여 고도, 토양 특성 및 우점종군에 따른 종다양성의 변활르 분석하였으며 종서열-중요치 곡선을 이용하여 각 식물의 우점서열을 결정하고 각 종이 식물군락 내의 자원을 어떻게 분배하고 있는가를 결정하였다 고도, 토양요인(pH, base) 및 우점종의 차이는 삼림의 종 다양성에 영향을 미치는 중요한 변수로서 작용하였으며 우점종군에 따른 다양성의 변화는 지형과 교란에 의하여 영향을 받았다 종서열-중요치 곡선에서 조사된 10개 군락은 대수정규분포에 접근하고 있어서 군락간 약간의 차이는 있지만 대체적으로 어떤 특정 종이 군집 내 자원 공간을 독점하지 않고 적절히 분배하여 사용하고 있었다.

Acute tubular necrosis (ATN) is a syndrome of intrinsic renal injury secondary to ischemic or toxic causes without parenchymal damages and usually non-oliguria. A 20-year old man presented with acute renal failure preceded by 2 days of watery diarrhea. He had been anuria for 48hr with intravenous fluid therapy. Oliguria persisted for 10 days and he required hemodialysis support for 6 days before renal recovery. He denied the use of any regular medication and any intravenous drug use. Renal biopsy revealed severe ATN. Histopathologic findings were marked desquamation of proximal tubular epithelial cells with intact distal tubules and normal glomeruli. We report an unusual case of ATN with anuria and clinically severe features.

Hydroureter could occur in a state where the whole ureter was remarkably expanded. The causes of occurrence are anatomi-cal urinary tract obstruction or vesicoureteral reflux, and it could occur unilaterally or bilaterally according to its reason. A 38-year-old man presented with left flank pain. Abdominal CT showed a severely atrophied left kidney and a large retroperi-toneal cyst near the left kidney. The pathologic finding showed that the cyst wall is composed of transitional epithelium, lamina propria, muscle, and adventitia, and final diagnosis was hydroureter. The unilateral marked hydroureter misdiagnosed as a retroperitoneal cyst was quite rare. We report on this rare case with literature.

Polyethylene glycol (PEG) solution is currently used to prepare the colon before colonoscopy. Hyponatremic encephalopathy is a condition with neurologic symptoms such as headache, vomiting, confusion, seizure, and sometimes respiratory arrest. A 55-year-old woman presented to our emergency department with generalized tonic-clonic seizure and mental change after ingestion of PEG solution 2 L with water. Serum sodium concentrations was 115 mmol/L. After correction with hypertonic saline for 12hrs, serum sodium concentration reached 129 mmol/L and mental status recovered. We experienced a case of acute hyponatremic encephalopathy resulting from ingestion of PEG solution 2 L for colonoscopy.

우리나라 약사법과 외국의 방사성의약품 제조관리기준 가이드라인을 참고하여 방사성의약품 제조관리기준 제정 시 고려해야할 사항들에 대해 의견을 제시하였다. 의약품은 안전성, 유효성과 더불어 제품의 균일성이 검증되어야 한다. 따라서 방사성의약품의 특성을 충분히 고려한 합리적인 제조관리기준을 제정하면 방사성의약품 관리의 효율성을 증대시키고 국민건강 증진에 기여할 수 있을 것으 로 기대된다.

The objective of the paper is to experimentally investigate the compressive strength of the concrete incorporating fly ash. Ordinary Portland cement(OPC). Water to binder ratio(W/B) ranging from 30% to 60% and curing temperature ranging from -10℃∼65℃ were also adopted for experimental parameters. Fly ash was replaced by 30% of cement contents. According to the results, strength development of concrete contained with fly ash is lower than that of plain concrete in low temperature at early age and maturity. In high curing temperature, the concrete with fly ash has higher strength development than that of low temperature regardless of the elapse of age and maturity. Fly ash can have much effect on the strength development of concrete at the condition of mass concrete, hot weather concreting and the concrete products for the steam curing.

Rare earth contents(REE) were analysed for the plants, M. sinensis, A. vulgaris and R. crataegitolius, from two different soils serpentine area consisting of serpentinite(SP) and non-serpentine area, containing amphibole schist(AS) of Gapyeong area, and were compared with soils and host rocks. The AS were high with the differences of several times in the top soils, and with the differences of several to ten times in the host rocks relative to the SP. In the same area, the SP were high in the soil, but the rocks for the AS. In the plants, the A. vulgaris were high, but low in the R. crataegitolius. Root parts were higher than the upper parts. Differences between the upper and root parts were big in the SP rather than the AS, and were big in the R. crataegitolius, but small in the M. sinensis. Among the parts of the plants, high elements were shown in the R. crataegitolius of the SP, and the A. vulgaris and M. sinensis of the AS. In the correlation coefficients, most of the REE showed positive relationships among the element pairs, especially high positive correlation coefficients in the upper parts of the SP. Differences of the soils and plants(average) were smalle in the M. sinensis and big in the R. crataegitolius. In the upper parts. contents of the A. vulgaris were close to the soils while the R. crataegitolius showed large discrepancies with the soils. In the root parts, contents of the A. vulgaris showed discrepancies with the soils regardless of soil types, but close in the R. crataegitolius of the SP and M. sinensis of the AS.

In this paper, estimation of the compressive strength of the concrete incorporating blast furnace slag subjected to high temperature was discussed. Ordinary Portland cement and blast furnace slag cement (BSC;30% of blast furnace slag) were used, respectively. Water to binder ratio ranging from 30% to 60% and curing temperature ranging from 20℃～65℃ were also chosen for the experimental parameters, respectively. At the high temperature, BSC had higher strength development at early age than OPC concrete and it kept its high strength development at later age due to accelerated latent hydration reaction subjected to high temperature. For the strength estimation, the Logistic model based on maturity equation and the Carino model based on equivalent age were applied to verify the availability of estimation model. It was found that fair agreements between calculated values and measured values were obtained evaluating compressive strength with logistic curve. The application of logistic model at high temperature had remarkable deviations in the same maturity. Whereas, the application of Carino model showed good agreements between calculated values and measured ones regardless of type of cement and W/B. However, some correction factors should be considered to enhance the accuracy of strength estimation of concrete.

Using the principal component analysis and clustering Forest resources are consistently necessary in the future. It takes much time to produce and breed them. However it is difficult to do due to recent social situation. Considering global environment, forest policy should be considered as a global scale rather than a regional one. At least, the policy needs a national scale concern. In order to support forestry, elementary data are needed. In this study, forest characteristics in Ishigawa-gen province have been analyzed through main component analysis and clustering. The results are shown in fig.5 and fig.6.

In this paper, removal time of side form from concrete using OPC(ordinary Portland cement) and FAC(fly ash cement) are proposed by appling logistic model, which evaluates the strength development of concrete with maturity. W/B, types of cement and curing temperatures are adapted as test parameters. The estimation of strength development by logistic model has a good agreement between calculated values and measured ones. As for the removal times of form works suggested in this paper, as W/B increases, curing temperature decreases and fly ash is used, removal time of side form is prolonged. Removal time of form from concrete using OPC suggested in this paper is shorter 2.5～3.5 days than those of KASS-5 (Korean Architectural Standard Specifications-5) in the range of over 20℃. And in the range of 10～20℃removal time of form is shorter than that of KASS-5 by as much as 4~4.5 days. The use of FAC results in an increase in removal time of form compared to that of OPC by about 1 day.

The purpose of this study is to select the appropriate wild herbaceous plants on the rooftop. For the purpose of the experiments, 14 wild herbaceous plants were chosen. As the results of the experiments, the wild herbaceous plants growing on the culture soil(perlite) Among the 14 kinds of wild herbaceous plants, such as Chrysanthemum boreale, Taraxacum mongolicum, Aster Koraiensis, Aster yomena, Oenothera odorata, Oenothera lamarckiana, Patrinia scabiosaefolia showed good effects on growth of above ground parts. Therefore, these plants will effective for the rooftop revegetation. Callistephus chinensis and Lotus corniculatus var. Japonicus showed good height growth, wherase covering rate was worst. Chrysanthemum boreale, Platycodon grandiflorum, Patrinia scabiosaefolia were plant height, wherase covering rate was not good . For the expected number of seedings more than 3,000 per square meter, many seedings got withered to death while the survivors were suppressed to grow slow in the early stage due to the densityproblem.
