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.

In sampling survey, nonresponse tend to occur inevitably. If we use information from respondents only, the estimates will be baised. To overcome this, various non-response imputation methods have been studied. If there are few auxiliary variables for replacing missing imputation or spatial autocorrelation exists between respondents and nonrespondents, spatial autocorrelation can be used for missing imputation. In this paper, we apply several nonresponse imputation methods including spatial imputation for the analysis of farm household economy data of the Gangwon-Do in 2002 as an example. We show that spatial imputation is more efficient than other methods through the numerical simulations.

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.

The objectives of this study were (1) to investigate the differences of evaluations of blue jean according to the level of apparel advertising acceptance, (2) to examine the differences of effect of brand name on evaluations of blue jean, (3) and to investigate the differences of evaluations between Clothing and Textiles majors and non Clothing and Textiles majors. Questionnaire was comprised of 10 Likert type items of apparel advertising acceptance measure, and 11 items of 7-point scale for clothing evaluation measure. `M`greger` was selected for the blue jean evaluations of unrecognized brand, and `Calvin Klein` was for recognized brand. The subjects were 154 college female students in Seoul; 39 females were asked about evaluations of the blue jean of unrecognized brand name (M^c greger) without the brand name label, 40 unrecognized brand with the label, 41 recognized brand (Calvin Klein) without the brand name label, 34 recognized brand with the label. The data were analyzed using t-test, one-way ANOVA, and Duncan`s multiple-range test. The results of the study were the followings: 1. Females with high scores in apparel advertising acceptance were more influenced by brand name in evaluations of blue jean than those with low scores. 2. The evaluations of blue jean was influenced by reputation of brand name in all evaluation criteria. Female group who evaluated the blue jean with recognized brand name label evaluated more positively than the other groups. 3. Clothing and Textiles majors were less influenced by the reputation of brand name in the evaluations of blue jean than non-majors.

본 연구는 유아교육 및 보육 현장에서 경험하고 있는 유아평가의 딜레마와 도전과제를 고찰하는 것을 목적으로 하였다. 유아교사들의 딜레마를 유아평가의 목적론과 관련된 본질적 딜레마, 기록 및평가 절차에 대한 방법론적 딜레마, 그리고 평가를 체계적으로 계획, 실행, 활용하는 실제를 둘러싼 현실적 딜레마로 나누어 각 딜레마별로 유아평가에 대한 이해와 실천의 지평을 확장할 수 있는 도전과제들을 짚어보았다. 국가수준 교육과정의 경직성과 각종 기관평가 및 질 관리를 통한 표준화에 대한 우려가 증가하는 상황에서 유아평가의 딜레마 극복을 위해서는 장기적 교육목표에 대한 새로운 비전 정립, 교사의 전문성과 자율성을 신뢰하는 사회문화 구축, 다양한 평가방법의 실천과 반성, 경계선을 넘어서는 열린 소통과 협력이 활발하게 이루어질 필요가 중차대함을 제안하였다. Lee. Jin-HeeThis study aimed at examining dilemmas and challenges that teachers in the field of early childhood education and care are experiencing with assessment of young children. Dilemmas are grouped into 3 categories: a) ontological dilemmas related to purposes and roles of early childhood assessment, b) methodological dilemmas regarding documentation and assessment, and c) practical dilemmas in terms of specific difficulties in planning, implementing, and utilizing systematic assessment, along with challenging tasks to deepen understandings of early childhood assessment and expand its possibilities in practice. As concerns are accumulated on the rigidity of national curriculum and standardization caused by institutional evaluations and quality control initiatives in early childhood education and care, it would be more vital than ever to work toward long-term pedagogical vision and goals, sociocultural values on professionalism and autonomy of teachers, experimentation of various assessment strategies and critical reflection, and open communication and collaboration among stakeholders in order to move beyond traditional borders and challenges.

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.

Aflatoxin $B_1$, a known human carcinogen, is the member of aflatoxin subfamily that is most frequently found in contaminated foods. Epidemiological studies have suggested that aflatoxins may be associated with human liver cancer and acute hepatitis. Recently it was reported that the traditional medical herbs sold in domestic markets are contaminated with aflatoxins. Long-term administration of these contaminated medicines could result in adverse health effects. Therefore, it is important to evaluate the levels of exposure to aflatoxin in people who ingest traditional herbal medicines. Blood samples were collected, before and after the herbal medicine intake, from 151 subjects who visited the hospital. The metabolite of aflatoxin $B_1$ in blood, aflatoxin $B_1$-albumin (aflatoxin $B_1$-lysine), is reportedly an appropriate internal exposure indicator, and its levels in the collected bloods were therefore analyzed using a liquid chromatography-mass spectrometry. The analytical method of aflatoxin $B_1$-lysine in blood was firstly optimized in Korea and the levels were detected below quantification limits (2 pg/mg albumin) in this study population. Consequently, the exposure levels of aflatoxin $B_1$ by ingestion of herbal medicines were low but it is important to monitor routinely due to the possibility of risk on the aflatoxin exposure.

Trench capacitors with four different structures were fabricated using plasma and reactive ion etching technique, and evaluated using their C-V and I-V characteristics. The results shows that the two step plasma etching technique is the best method to fabricate the trench capacitor because of its high breakdown field (~7.75 MV/Cm) and good step coverage. And the fixed oxide charges are comparable between the trench (3.6xE10/Cm\ulcorner~7.5xE10/Cm\ulcorner and the planar(4.5xE10/Cm\ulcorner~6.5E10/Cm\ulcorner capacitors.

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.
