Collated data from the 1995-1996 floristic surveys of weeds of arable peat in Selangor district were analysed to assess composition and dominance and spatial distribution pattern based on quantitative and dispersion indices. Forty eight weed species belonging to 19 families of which 31 were broad leaves, 10 grasses and 7 sedges were sampled and these ware translated as 77.8 and 15% of the total cover, respectively, The respective important values were 71.11 and 18%. Ten species in the onder of dominance were Fimbristylis acuminata, Murdannia nudiflora, Hedyotis corymbosa, Ageratum conyzoides, Asystasia gangetica, Cleome rutidosperma, Cyperus sphacelatus, Lindernia crustacea, Ludwigia hyssopifolia of spatial distribution based on variance-to-mean ratios, Llouds mean crowding or Lloyds patchiness indices. Other species were either random or regular in their spatial distribution. Differences in species-dominance and spatial distribution pattern may be attributed to inherent variations in patchiness and fecundity schedules of each weed species, crops, cropping patterns and agronomic practices prevailing in the area. 말레이지아 Selangor지역(地域)의 부식질 경지토양(耕地土壤)에 분포(分布)하고 있는 경지(耕地)의 잡초식생(雜草植生)을 조사하고 정량적 생태분석을 수행한 결과는 다음과 같이 요약(要約)된다. 1. 이 지역(地域) 경지잡초(耕地雜草) 종조성(種組成)은 19과(科)에 속하는 31종(種)의 광엽잡초(廣葉雜草), 10종(種)의 화본과(禾本科) 잡초(雜草), 7종(種)의 사초과(莎草科) 잡초(雜草)로 이루어졌고, 잡초(雜草)의 식생피도(植生被度)에서 각각 77. 8. 15%를 점유하였으며, 이들의 중요도(重要度)는 각각 71, 11, 18%이었다. 2. 이 지역(地域) 경지잡초(耕地雜草)중 10종(種)의 우점종(優點種)은 우점도(優點度) 순위(順位)에서 Fimbristylis acuminata, Murdannia nudiflora, Hedyotis corymbosa, Ageratum conyzoides, Asystasia gangetica, Cleome rutidosperma, Cyperus sphacelatus, Lindernia crustacea, Ludwigia hyssopiflora 및 Ludwigia perennis이었다. 3. 이상과 같은 초종간(草種間) 우점도(優點度) 및 공간분포유형(空間分布類型)의 차이(差異)는 각 초종(草種) 본래(本來)의 종자생산성(鐘子生産性) 및 번식습성(繁殖習性)과 군집성(群集性)의 차이(差異)와 이 지역(地域) 경지(耕地)의 작물종류(作物種類), 작부체계(作付體系) 및 경종방법(耕種方法)과 제초관행(除草慣行)의 차이(差異)에 기인하는 것으로 생각한다.

상염색체 우성 다낭신 환자에서 신장 해부학적 지표에 따른 고혈압과 신기능의 변화

이규백(Kyu Beck Lee),김향(Hyang Kim),이영래(Young Rae Lee) 대한신장학회 2001 Kidney Research and Clinical Practice Vol.20 No.2

상염색체 우성 다낭신(ADPKD)은 다낭신 유전자를 받은 환자에서 점진적으로 신장에 낭종들의 수와 크기가 커져서 신혈관과 신실질을 압박하여 고혈압, 신부전을 발생시킨다. 그리고 ADPKD 환자에서 고혈압과 신부전 발생 이전부터 신장의 해부학적 변화가 발생한다. 따라서 오랜 기간의 임상경과를 가진 ADPKD에서 신장 해부학적 지표에 따른 고혈압과 신기능 변화를 평가하는 것은 중요하다. 그리고 신장 해부학적 지표를 ADPKD의 임상경과를 예측할 수 있을지를 알아보는 것은 의미 있다. 본 연구에서 강북삼성병원을 내원한 ADPKD환자 가운데 복부초음파검사로 진단하고, 해부학적 구조를 정확히 볼 수 있는 복부 전산화단층촬영을 시행한 67명의 환자를 대상으로 신장 해부학적 지표에 따른 고혈압, 신기능을 비교하였다. 한명의 방사선과 전문의가 복부 전산화단층촬영 필름을 분석하여 신장의 해부학적 지표로 신장의 길이, 용적, RSI(anatomical renal severity index), 최대 신낭종직경을 측정하였다. ADPKD 환자(평균 연령 45±12세, 남녀비42:25) 가운데 고혈압은 41명(61%)에서 있었으며, 신기능 부전 (크레아티닌 청소율50mL/min/1.73m2 이하)은 15명(22%)에서 있었다. 정상 혈압 군에 비하여 고혈압 군에서 신장길이, 신장용적, RSI, 최대 신낭종직경 모두 유의하게 증가되어 있었다(p<0.01)(신장용적 360±154mL/1.73 m2 대 833±585mL/1.73 m2 ). 정상 신기능 군에 비하여 신부전 군에서 신장길이, 신장용적, RSI, 최대 신낭종직경 모두 유의하게 증가되어 있었다(p<0.01)(신장용적499±335mL/1.73 m2 대 1171±700mL/1.73m2 ). 환자의 크레아티닌 청소율은 신장 해부학적 지표인 신장길이(r= -0.39), 신장용적(r= -0.49), RSI(r= -0.39), 최대 신낭종직경(r= -0.38)과 유의한 상관관계가 있었다(p<0.01). 본 연구 결과 ADPKD 환자에서 신장 해부학적 지표인 신장길이, 신장용적, RSI, 최대 신낭종직경은 고혈압, 신기능과 상관관계를 가지고, 고혈압 군과 신부전 군에서 증가되어 있다. ADPKD에서 신장의 낭종이 많아지고, 신장이 커질수록 고혈압이 발생하고, 신기능이 감소함을 객관으로 증명하였다. 향후에 ADPKD환자의 임상경과를 보는데 이러한 신장 해부학적 지표를 유용하게 사용할 수 있을 것으로 생각된다. Autosomal dominant polycystic kidney disease (ADPKD) is a common hereditary disorder, and its major morbidities are hypertension and renal failure. It is a characteristic feature of ADPKD that renal cysts increase in size and number with age continuously. Hypertension and renal failure in ADPKD result from compression of residual normal renal parenchyma by expanding cysts, since renal tissue is trapped within the poorly distensible renal capsule. Renal structural deformities in ADPKD occur prior to hypertension and renal failure. The present study was undertaken to explore the potential role of renal cyst enlargement in initiating hypertension and renal failure in ADPKD. We therefore measured renal structural indices by computed tomography(CT) to examine the relation between clinical progression and renal structural deformities. Sixty-seven adult subjects(45±12 years, rnale-female ratio 42: 25) with ADPKD were studied at our PKD clinic from 1997 to 2000, and a complete abdominal CT was performed on all subjects. One radiologist measured the renal structural indices which were renal length, volume, RSI(anatomical renal severity index) and maximal cyst size. The renal structural indices were significantly greater in hypertensive group compared to the normotensive group (hypertensive 833±585 vs. normotensive 360±154mL/ 1.73m------------², p<0.01). The renal structural indices were significantly greater in renal failure group compared to the normal renal function group(renal failure 1,171±700 vs. normal 499±335mL/1.73m², p<0.01). The renal function in ADPKD correlated with the renal structural indices. We concluded that the clinical progression in ADPKD correlates with the renal structural indices well. These structural indices provide considerable information about the progression of ADPKD.

The mushrooms collected at seven areas of Mt. Chiak in 2002 and 2003 were classified to analyse the distribution and species diversity. Frequency (number of mushroom: N), number of species (S), relative species density (RSD), similarity index (C), richness index (R1), variety index (V1), evenness index (E2), and dominance index (D1) were investigated. Total N and S was 143 and 84, respectively. The RSD was 0.179 ~ 0.226 of the 7 areas. The yearly C of the total area (0.213) was 8.2%. more higher than the average C of 7 areas (0.131). The order in the coefficient of variation (CV) of the indicator for 7 areas was N (10.5%) > D1 (9.2%) > V1 (8.9%) > S (8.5%) > R1 (7.4%) > E2 (2.2%). The average R1 of the 7 areas was 5.36 with the range from 4.85 to 6.01, and 16.72 for the total area. The average V1 of the 7 areas was 16.24 with the range from 14.44 to 18.66, and 68.82 for the total area. The average E2 of the 7 areas was 0.95 with the range from 0.926 to 0.982, and 0.819 for the total area. The average D1 of the 7 areas was 0.071 with the range from 0.055 to 0.073, and 0.081 for the total area. The correlation between N and 5 kinds of diversity indicator (S, R1, V1, E2, D) was not statistically significant, but the correlation between R1, E2 and D1 was statistically significant each other.

Development of Site Index Equation and Curves for Site Quality Assessment of Pinus caribea Monoculture Plantations in Southwestern Nigeria

Oyebade, Bukola Amoo,Osho, Johnson Sunday Ajose,Adesoye, Peter Oluremi Institute of Forest Science 2014 Journal of Forest Science Vol.30 No.4

Forest timber production potential of any site is oftentimes measured quantitatively by site index, which is defined as dominant height of a particular stand at a specified age. A site index was developed for estimating site quality of monoculture Pinus caribaea plantations in southwestern Nigeria using a base age of 25 years. Dominant height data were collected from 60 Temporary Sample Plots (TSPs) of $20{\times}20m$ in plantations of 15 to 37 years. Linear and non-linear models as been widely applied in quantitative forest measurements were fitted to dominant height-age data and the best site index equation is : $SI=Exp^{(InHd-23.495(A^{-2}-0.04)}$. The site index curves constructed for the three sites (Omo Forest Reserve - OFR (J4), Oluwa Forest Reserve - OLFR and Shasha Forest Reserve - SFR) across the southwestern Nigeria using the chosen equation revealed that a 15 year old Pinus caribaea in the study area attained average dominant heights of 25, 22 and 21 m in OFR (J4), OLFR and SFR respectively. The site index equation and curves proffer veritable insight into better silvicultural options and management practices for the future plantations suitable sites.

저서성대형무척추동물은 수질 평가를 위해 다년간 이용되었다. 본 연구는 한국 송지천에서 저서성대형무척추동물을 이용하여 이 하천의 수질을 평가하고자 수행되었다. 동정된 동물은 3문 5강 12목 18과 20종 447개체였다. 집모기류(Culicini sp.)가 가장 우점종이었고(203개체), 두번째 우점종은 집파리(Musca domestica)였다. 다양한 생태학적 척도로 수질의 상태를 평가하였다. 전체 생태 점수(total ecological score of benthic macroinvertebrate community, TESB)은 17(St. D)에서 41(St. A)으로 평균은 29였다. St. A에서 부수성 지수와 저서성 대형무척추동물 생태 점수(ESB)는 II 등급으로 빈부수성, 수질은 약간 만족이며 보호가 요청되는 수질에 해당되었다. 저서성동물지수(benthic macroinvertebrate index, BMI)은 25.207(St. C)에서 39.348(St. A)까지 이며 평균은 31.810였다. St. C와 St. D의 하천 상태 평가는 강부수성이며 민감종이 결여되어 있었다. 다양도를 나타내는 Shannon-Weaver index(H´)는 1.288(St. D)에서 2.250(St. A)였다. H’에 근거한 부수성 정도는 St. A에서는 β-중부수성이었으며 나머지 지점은 α-중부수성이었다. 지리적 밀도는 1.229(St. A)에서 2.071(St. D)으로 평균은 1.582였다. 송지천에서 사용한 무척추동물을 이용한 여러 수질의 척도는 한국 내 다른 하천에서도 적용할 수 있을 것이다. Benthic macroinvertebrates were analyzed in March, June, September, and December 2018 to evaluate water quality in the Songji River in Sacheon-ci, Korea. The identified benthic macroinvertebrates included 447 individuals belonging to 20 species, 18 families, 12 orders, 5 classes, and 3 phyla. Various ecological parameters were estimated for evaluation of the river status. The total ecological score of benthic macroinvertebrate community (TESB) varied from 17 (Station D) to 41 (Station A). The saprobic index and ecological score of benthic macroinvertebrate community (ESB) for the evaluation of river status revealed a water quality evaluation at Station A of II (oligosaprobic), indicating some satisfactory water protection. The benthic macroinvertebrate index (BMI) varied from 25.207 (Site C) to 39.348 (Station A). The evaluation of the river status at Stations C and D was polysaprobic, and sensitive taxa were absent. The mean Shannon-Weaver index (H´) of diversity varied from 1.288 (Station D) to 2.250 (Station A). The classification of saprobity based on H’ was β-mesosaprobic at Station A and α-mesosaprobic at the other stations. The value of geometric density was varied from 1.229 (Station A) to 2.071 (Station D), with a mean of 1.582. An artificial load is being added to this river. One of load is the rectal river construction which flows straight through the river physics. Thus, the environment of living organisms deteriorates due to insufficient water. In order to secure the quality of the Songji River and a good environmental habitat, several low-height stepped-beam structures are required.
