The sources of the pollution on a river are divided into two classes, one the point source and the other non-point source. In raining, especially, the non-point source discharged from paddy, residential area, road ${\cdots}$ etc have correlations with the land use. This study was carried out to find out the model to estimate the quality of water in a river according to the land use. Land use data (Pungse-Myeoun and Kwangduk-Myeoun in Chonan) were produced from Landsat TM (Thematic Mapper) and topographic map. Total nitrogen(TN) and total phosphorus(TP) general indices for the degree of pollution in river were measured during 11 months. Correlations between two variables(Land use and Pollutants(TN, TP)) were explained by the regression coefficient. As a result of this study, we found that among the five types of land use, the residential area, store area and paddy have significant effects upon the quality of water in a river. The results of this study will be applied to pre-estimate the degree of pollution in river broadly and to offer basic data in establishing the land use plan and the concept on the conservation of the river in rural area.

공간-시계열 모형을 이용한 결측대체 방법에 대한 연구

이진희,신기일,Lee, Jin-Hee,Shin, Key-Il 한국통계학회 2007 응용통계연구 Vol.20 No.3

표본조사에서 항목무응답 발생 시 결측대체에 사용되는 일반적인 방법은 결측변수와 관계 있는 보조변수를 이용하는 것이다. 최근 이진희 등 (2006)은 2002년 강원지역의 농가경제 자료를 이용하여 표본조사에서 공간통계를 이용한 결측대체 (missing imputation) 방법을 비교하였으며, 자료들 사이에 지역적 상관이 존재할 때 이를 이용한 결측대체가 효율적임을 보였다. 본 논문에서는 이를 확장한 개념으로, 강원지역의 2000-2002까지의 월별 자료가 공간상관과 시계열상관이 존재함을 확인하고 이 관계를 결측대체에 이용하였다. 또한 공간상관과 시계열상관이 모두 존재할 경우 공간시계열 모형을 이용한 결측 대체 방법이 공간모형을 이용하였을 때에 비해 더 효율적임을 모의실험을 통해 확인하였다. It is a common practice to use the auxiliary variables to impute missing values from item nonresponse in surveys. Sometimes there are few auxiliary variables for missing value imputation, but if spatial and time autocorrelations exist, we should use these correlations for better results. Recently, Lee et al. (2006) showed that spatial autocorrelation could be efficiently used for missing value imputation when spatial autocorrelation existed, using the data from the farm household economy data in Gangwon-do, 2002. In this paper, we present au evaluation of spatial and space-time nonresponse imputation methods when there exist spatial and time autocorrelations using the monthly data during 2000-2002 from the same data previously used by Lee et al. (2006). We show that space-time imputation method is more efficient than the other through the numerical simulations.

이진희,이현승,이근영,장필상,이경일,김동언,Lee, Jin-Hee,Lee, Hyun-Seung,Lee, Keun-Young,Jang, Pil-Sang,Lee, Kyung-Yil,Kim, Dong-Un 대한소아신장학회 2007 Childhood kidney diseases Vol.11 No.2

목 적 : 육안적 또는 현미경적 혈뇨를 주소로 24시간 소변화학검사를 시행한 환아들의 의무 기록을 후향적으로 조사하여 고칼슘뇨군과 비고칼슘뇨군으로 나누어 두 군의 혈액 및 소변화학검사와 그로부터 계산된 각 용질의 배설량, 청소율, 분획배설 등에 있어서 두 군간에 차이점이 있는지 비교하였다. 방 법 : 1997년 2월부터 2007년 2월까지 10년간 가톨릭의대 의정부성모병원 소아과에서 육안 또는 현미경적 혈뇨를 주소로 24시간 소변검사를 시행한 환아 중, 단백질 배설량이 4 mg/$m^2$/시간 이상으로 단백뇨가 동반된 경우는 제외하고, 소변 칼슘 배설량이 4 mg/kg/일 이상으로 특발성 고칼슘뇨증으로 진단 받은 30명과 소변 칼슘배설량이 3mg/kg/일 미만인 비고칼슘뇨군 환아 41명을 대상으로 하여 혈액화학검사, 기본 소변검사, 24시간 소변화학검사로부터 각종 소변 용질의 배설량, 청소율, 분획배설 등을 구하여 두 군간에 차이점이 있는지를 비교 분석하였다. 결 과 : 고칼슘뇨군(30명)과 비고칼슘뇨군(41명)에서 육안적 혈뇨는 각각 24명(80%), 17명(42%)으로 고칼슘뇨군에서 육안적 혈뇨의 비가 높았다. 임의채취뇨의 Ca/Cr 비는 각각 $0.34{\pm}0.15,\;0.15{\pm}0.13$이었으며 고칼슘뇨군 30명 중 28명의 임의채취뇨 Ca/Cr 비는 0.2 이상이었고, 비고칼슘뇨군 41명 중 36명의 임의채취뇨 Ca/Cr 비가 0.2 미만이었다. 혈액화학검사에서 고칼슘뇨군과 비고칼슘뇨군의 혈청 칼슘은 각각 $9.8{\pm}0.5 mg/dL,\;9.5{\pm}0.5 mg/dL$로 고칼슘뇨군이 통계학적으로 유의하게 높았다(P=0.033). 24시간 소변의 칼슘농도는 각각 $14.7{\pm}7.7 mg/dL,\;3.3{\pm}2.2 mg/dL$로 고칼슘뇨군이 유의하게 높았고(P<0.001), 칼슘배설량도 각각 $6.1{\pm}2.9 mg/kg/$일, $1.5{\pm}0.9 mg/kg/$일로 고 칼슘뇨군에서 유의하게 높았다(P<0.001). 크레아티닌 청소율로 구한 사구체여과율은 각각 $93.7{\pm}31 mL/min,\;79.5{\pm}32.0 mL/min$로 고칼슘뇨군이 유의하게 높았다(P=0.048). 24시간 소변의 요소농도는 각각 $797{\pm}316 mg/dL,\;569{\pm}329 mg/dL$로 고칼슘뇨군에서 유의하게 높았고(P=0.015), 요소배설 량도 각각 $341 {\pm}102 mg/kg/$일, $233{\pm}123 mg/kg/$일로 고칼슘뇨군에서 유의하게 높았다(P=0.002). 나트륨 배설량은 두 군간에 차이가 없었으나 나트륨 분획배설(FENa)은 각각 $1.0{\pm}0.4%,\;1.3{\pm}0.6%$로 고칼슘뇨군에서 유의하게 낮았다(P=0.029). 소변배설량은 두 군간에 차이가 없었으나 소변의 삼투질농도는 각각 $393{\pm}103 mOsm/kg\;H_2O,\;304{\pm}96 mOsm/kgH_2O$로 고칼슘뇨군에서 더 농축된 소변을 보았다(P=0.003). 결론 :고칼슘뇨군의 소변화학검사의 가장 특징적인 소견은 요소 배설과 사구체여과율의 증가로서 이는 고칼슘뇨군이 비고칼슘뇨군에 비하여 고단백식이를 하고 있을 가능성을 시사한다. 나트륨과 칼슘은 사구체 여과가 증가함에 따라 원위세뇨관 및 집합관에 도달하는 양도 증가하고 그 곳에서 나트륨의 재흡수 기전이 매우 정교하게 이루어지는데 비하여 칼슘의 그 것은 그렇지 못하여 고칼슘뇨증을 일으켰을 가능성이 있다. 향후 고칼슘뇨 환아를 진료함에 있어서 단백질 섭취 등식이 습관의 문진과 함께 식이요법도 고려해 보아야 할 것으로 생각된다. Purpose : The purpose of this study was to investigate whether hypercalciuria patients with hematuria show different renal indices compared to non-hypercalciuria patients with hematuria. Methods : We retrospectively reviewed the medical records of patients with gross or microscopic hematuria whose blood chemistry and 24 hour urine chemistry were examined. After excluding the patients with more than $4 mg/m^2/day$ proteinuria or the patients with urinary calcium excretion between 3 and 4 mg/kg/day, we divided the patients into two groups: a hypercalciuria group whose calcium excretion was more than 4 mg/kg/day(n=30) and a non hypercalciuria group whose calcium excretion was less than 3 mg/kg/day(n=41). The urinary excretion, clearance, and fractional excretion(FE) of Na, K, Cl, Ca, P, urea, and creatinine were calculated and compared between the two groups. Results : The hypercalciuria group had more calcium excretion($6.1{\pm}2.9$ vs $1.5{\pm}0.9 mg/kg/day$), more urea excretion($341{\pm}102$ vs $233{\pm}123 mg/kg/day$), greater glomerular filtration rate(GFR) ($93.7{\pm}31.1$ vs $79.5{\pm}32.0 mL/min$) but lower FENa($1.0{\pm}0.4%$ vs $1.3{\pm}0.6%$) than the nonhyper-calciuria group, although the urinary sodium excretion was similar between the two groups. Conclusion : The greater urea excretion and GFR in hypercalciuric patients suggest that they might be on a higher protein diet than the non-hypercalciuria group. The increased glomerular filtration of sodium and calcium induced by the higher GFR in hypercalciuria would have increased their delivery to the distal tubule, where sodium is effectively reabsorbed but calcium is not, which is suggested by the lower FENa but higher FECa in hyercalciuria. It is recommended that the diet of hematuria patients be reviewed in detail at initial presentation and during treatment.

This study covers centrality of villas after Renaissance and architectural forms corresponding to the nature in the aspect of Karl Popper and Gilles Deleuze. In addition, the researcher tries to understand the changes in architectural forms according to the changes in places. To do that, Pascal and Hans Meyer's theory was introduced as a major theory. The researcher tries to set up the standard by analyzing the architectural form related with the nature and the form of center in the housing through Villa Rotonda and Villa Emo. And with key analysis of the centrality and architectural form corresponding to the nature and the four houses that are historically and morphologically important. It is found that due to the development in modern technology and materials, a variety of architectural approach is developed and they are implemented as various architectural forms. However, due to various theories of modern architectural approach, it is found that the morphological differences of suburban housing exists by forming a universal relationship constructed by four architects. The researcher expects to be understood and realized in real life construction.

The mixed rural city is adjusting to change by urbanization. The recent landcover change in mixed rural city is an important factor that changes structure and function of regional ecosystem. Landscape ecology is an integrated ecology widely available for environmental science such as nature conservation and sustainable land-use planning. As the concern about environmental quality rises, many studies are trying to create and conservate for biotop. The creation of biotop is related to the plan and management of the effective landuse because the important factor to change the structure and function of ecological area in the country. This study was carried out to establish the foundation of the landuse plan to analyze the change of landuse and to plan the scheme in creating biotop and landuse. We used the approach of ecological landscape and using landscape indices with RS(Remote Sensing) and GIS(Geographic Information System) technology, spatio-temporal variations of areas and distribution of forest patches were examined in the Sunghwan in Chonan from 1985 to 1996. A result of this study showed that the area of forest and paddy decreased by urban sprawl. The size of patch in the forest and agriculture had been smaller and irregular form, heterogeneity of size of forest and agriculture patches within sub-basin was increased, pattern of forest and agriculture patches decreased the corridor and network from 1985 to 1996.

In order to study the interrelationships of dietary such factors as wheat bran, calcium and salt a total number of 480 broiler chicks of Hisex-Hibro strain was fed 3 × 2 × 2 factorially arranged experimental diets for 28 days. In the present experiment were used 3 levels of dietary wheat bran (0, 5, 10%), 2 levels of dietary calcium (0.9, 1.5%) and two supplemental salt levels (0.3, 1.0%). Body weight gain, daily feed intake, feed efficiency and gall bladder weight were measured. And bone calcium content, bone ash content, serum calcium content and serum sodium content were also measured. The results observed in the present study are summarized as following: 1. Body weight gain was gradually and insignificantly decreased as dietary level of wheat bran was increased, and dietary levels of calcium and salt failed to show any significant effects on the body weight gain. But high Ca × high salt gained slightly more body weight than low Ca × low salt. 2. Feed intake was significantly decreased (p$lt;0.01) as the level of wheat bran was increased. Interaction of wheat bran with dietary levels of salt or calcium were found significant (p$lt;0.01); increased level of wheat bran resulted in decreased feed intake when salt level was lowered or when calcium level was increased. 3. Feed efficiency was not affected by any combination of dietary level of the experimental materials, although high Ca × high salt groups showed slihtly improved values. 4. Weight of gall bladder was increased as dietary level of wheat bran was increased or as dietary level of calcium. was decreased (p$lt;0.05), and high salt × high Ca showed heavier gall bladder weight than low salt × low Ca. 5. Bone calcium content was not significantly affected by treatments, except decrease (p$lt;0.05) with high level of wheat bran. Bone ash retention was increased with high dietary salt level and it was more pronounced with high calcium level. 6. Serum calcium content was increased as the dietary levels of wheat bran and calcium were increased (p$lt;0.01). Serum calcium with low calcium × high salt was decreased, but with high calcium × high salt decreased. Serum sodium level was increased with increased dietary levels of calcium or salt (P$lt;0.01), and it was affected by dietary wheat bran level (p$lt;0.01) and seems to be due to interaction between dietary levels of wheat bran and salt.

Fibrin Polymer 의 생성 메카니즘에 관한 연구

이진희,김두식 ( Jin Hee Lee,Doo Sik Kim ) 생화학분자생물학회 1988 BMB Reports Vol.21 No.4

Conversion of fibrinogen to fibrin polymer has been investigated. It is noteworthy to find that excess basic amino acids, either L-arginine or L lysine, are capable of polymerizing fibrinogen at neutral pH simply by charge-neutralization process without removing fibrinopeptides. This observation strengthens the notion that both specific orientation and balance of electric charge of the protein molecule are essential factors for the fibrin polymerization. Chemical modification of arginine residue(s) of fibrinogen completely inhibits thrombin-catalyzed conversion to fibrin polymer, which confirms that the specific arginine is recognized as a cleavage site by thrombin to yield fibrinopeptides and fibrin. The molecular weights of three different polypeptide chains of fibrinogen are reduced to lower than 47,000 upon proteolytic digestion with chymotrypsin. Surprisingly, however, these lower molecular species of fibrinogen are found to be polymerized in the presence of thrombin. Therefore, extensive structural analyses of the chymotrypsin-treated fibrinogen will contribute to define the essential interaction domains of fibrin units required for polymerization.
