The aim of this paper is to evaluate users' benefit values of theme park using Travel Cost Method with special reference to Woobang Tower Land in Taegu for the estimation of economic values. This research is mainly based on questionnaire survey of 100 users of the theme park. Socio-economic factors such as income, year of education, annual income, age and money(travel cost) are analysed from 5 residential areas of the respondents. Multiple regression analysis was used for the evaluation of annual number of park visitings based on the analysis. The regression model shows NV = α + β1TC + β2INC + β3EDU + β4AGE (NV : Annual Number of Visitings, TC : Travel Cost, INC : Annual Income, EDU : Years of Education, AGE : Age). Regarding to visitors demand curve based on the equation showed that annual economic values of Woobang Tower Land was estimated as 50billion Korean Won.

Estimation of current and future loading from watershed is necessary for the sound management of water quality of an estuary lake. Pollution sources of point and non-point source pollution were surveyed and Identified for the Koheung watershed. Unit factor method was used to estimate potential pollutant load from the watershed of current conditions. Flow rate and water qualify of base flow and storm-runoff were monitored in the main streams of the watershed. Estimation of runoff pollutant loading from the watershed into the lake in current conditions was conducted by GWLF model after calibration using observed data. Prospective pollutant loading from the reclaimed paddy fields under cultivation conditions was estimated using the modified CREAMS model. As a result, changes of pollutant loading into estuary lake according to non-cultivation and cultivation conditions of reclaimed tidal land were estimated.

In this paper, properties of hydrologic cycle in three experimental catchments were compared and different types of a lumped parametric model were applied to understand the hydrologic cycle in the catchments. One of them is a forest catchment and another

The purposes of the study were to detect and evaluate the historical land use and land cover changes on the Balan watersheds from three thematic mapper (TM) data, which were taken in 1985, 1993, and 1996. The supervised and unsupervised classification methods were adopted to classify five land cover categories: Paddy, upland, forest, residential, and water. The results indicated residential areas increased significantly during the past eleven years, Forest and paddy were converted to the urban areas. Future land cover patterns were forecasted using a Markov chain method, and the simulated land coiler change ratios presented.

The experiment was carried out to study the variations and geographical distribution of β -amylase isozyme by isoelectric focusing (IEF) within Korean, Chinese and Japanese soybean land races. In pH 3-10 gel of IEF, the amylase of soybean accessions was separated into low pI group isozymes (TEX>Sp1 b) and high pI group isozymes(Sp1 a). In pH4-6.5 gel, isoelectric points were at 5.07, 5.15, 5.25, 5.40, and 5.94, and h, j, and k bands also were found. The distribution of Sp1 a allele (high pI type) was 29.3% in soybean accessions from Korea, 10.1 % in those from China, and 6.9% in Japanese accessions. The percentage of Sp1 a) allele was the highest in soybean accessions from Kyungsang province (35 %) in Korea, then central China (32 %) in China, and Honshu (10%) in Japan

This study of modernism examines the antithesis between high art and mass culture, which Andreas Huyssen closely analyzed in After the Great Divide (1986). Calling this antithesis the divide, Huyssen elaborated the Adomo/Horkheimer version of this chasm. Suggesting the necessary relationship between "High Modernism" and mass culture, Huyssen marked a comer of modernism--that is to say, the avant-gardism-- that had a positive relationship to mass culture. Dealing with the formation of early modernism and its avant-gardism, first I explore how modernism fits into the commercialization of the industrialized society. Modernist works become the commodities in mass culture, even while modernist writers assume "relentless hostility" to the conversion of their works into "easily consumed products." Though the unearthing early modernism has many controversial facets and writers, I mainly focus on Eliot and Pound, briefly presenting the examples of H. D., Joyce, and Lawrence. As Pound declares, Eliot's The Waste Land was a landmark that manifested the justification of the movement of their modem experiment since 1900. Pound was deeply involved in the editing stage of The Waste Land as well as in the historical process of its publication. As Lawrence Rainey says, the price of The Waste Land was actually that of literary modernism. Along with the historical account of marketing modernist works, literary journals between 1900-1930 are also crucial, in that they were the important venues for modernist poetic experimentation and avant-gardism and of first to publish modernist writers' works. For instance, in 1917, the editors of The Little Review, the American avant-garde magazine, proclaimed that they would "make no compromise with the public taste." However, at the same time, by employing a prominent advertising agent, they adopted plans to market the magazine. This inconsistency can be also found in the marketing strategy of The Egoist, for the poet Richard Aldington even suggested hiring sandwich-board man to march around London advertising and selling copies of The Egoist. While Eliot's The Waste Land was a terminal result of modernist poetic experimentation and avant-gardism since 1900, his and Pound's marketing strategy of The Waste Land was also to follow its determined course as in other modernist writers'. Thus, the publication of The Waste Land inevitably records the canonization and commercialization of literary modernism, which were socially and historically constituted.

The purpose of this paper is to present the environment change of Cheju Island as land development process using GSIS(Geo-Spatial Information System) technique. We implemented the process based on the maps of soil color, underground water pollution points, land use, land development planning and land sight seeing supported by Cheju Province Office. To use the maps for GSIS data, first we transformed the picture data of the office into raster structured picture data using scanner. Second, the coordinate system was added to raster data using 1/50000 geographic map. Third, we estimated land planning process using GSIS technique(overlay and reclass technique). The results showed that land development effected the natural environment(forest, green field, farm land). However, the chemical pollution and land sight seeing was not so much effected by the land development that was found.

In spite of importance of the farm area in the city, the urbanization and industrialization strongly results in decrease of the farm area. The purpose of this study is to establish an effective way of agricultural land uses by examining on the intention of the farmers based on the survey in Seoul area. The areas, the agricultural types, the landowner's ages, and farm land sizes, were surveyed and analyzed with respect to urban agricultural planning and land use planning. All the collected data were basically analyzed with Contingency Table and Chi-square Test using SAS statistical package. The structures of the intention of agricultural land uses were understood with the comparative analyses of the agricultural land owners, the agricultural land leaseholders, the areas, landowner's ages, farming types, and so on.

The purpose of this study was to propose section designs for the ecological improvement of streams in rural villages in Korea. According to the survey about ecological conditions of rural streams of 10 selected rural villages (sep., 1996), the streams could be classified into three divisions(upstream, inner village, downstream), and the average width of streams was 9m, and the height of banks 3.1m. The slopes of basin were 7.33%, 2.67%, 1.39% at upstream, inner village, downstream respectively. The survey about the residents' usage of stream and the preferred activities(jun., 1997) showed that the streams were most frequently used for the supply of agricultural water use(39%), for the washing(15%) and for the recreation and rippling(10%), etc.. Three standard designs were presented for upstream, inner village, and downstream, and three standard sections were made by each designs. For the upstream division, it was designed to be used for the recreational activities in summer and the major stream bank materials were base rock and existing boulders with least artificiality. As the streams in the residential area were expected to be frequent access and used by the residents, most facilities for the streamside activity such as waterfront, water holes, shallows, walk were concentrated in this part with some artificiality. The downstream was designed for the agricultural activities such as water supply, space for the preparation of work and some break during the work.

Estimating dimensions of attractors are the most basic tools to analyze properties of chaotical dynamic systems. In this paper, we estimate correlation dimensions of meteorological variables, such as wind speed (v) and temperature (T) observed in Kimhae International Airport when the land-sea breeze circulation is appeared and find low non-integer values that reflect the deterministic chaos characterizing the dynamics. We compare the results with the correlation dimensions of 2-dimensional model that is calculated by finite element method. Though the correlation dimensions of the calculated wind speed (v) are less than those of the observed wind speed (v), we can suggest that the land-sea breeze circulation has not a unique mechanism. The land-sea breeze phenomenon is a complicated dynamics, which is constructed with various scale motions of atmosphere. In further research, we hope to find more accurate dynamics of land-sea breeze through wide observations and using of more sophisticated prediction models.

The extent of heavy metal pollution in agricultural soils near the abandoned mine land site was investigated using their concentrations from the 47 sampling sites in B mine. Samples were prepared using 0.1N HCl -Korean Standard Methods- and then analysed for Cd, Cu, Pb, As and Cr by Inductively Coupled Plasma Spectrometer. In addition, soil and mine tailing samples were sequentially extracted to investigate the chemical speciation of heavy metals in them. The soils in the vicinity of mining area are highly contaminated by heavy metals ranging up to 5.96㎎ Cd/㎏, 253.3㎎ Cu/㎏, 76.7㎎ Pb/㎏, and 15.45㎎ As/㎏, according to the analysis of Korean Standard Methods. The heavy metal levels by the sequential extraction are much higher than its level by Korean Standard Methods, and little correlated with each other. Based on the results, it is suggested that the As pollution in agricultural soils near the AMLS should be dealt as of prior significance in establishing reclamation strategies for the area.

The applicability of resistivity cone for contaminant investigation in farm land was examined in laboratory and in-situ. To verify the resistivity variations in sand with contaminants, laboratory experiment used soil resistivity test box was performed. Heavy metal and others ions were appeared steep variations in low concentration. Pilot test results were the same as laboratory test results. In the in-situ test used resistivity cone, resistivities of waste landfill layer were low than the common soil layers and resistivities had been difference with concentration of contaminant components. Therefore contaminant investigation in farm land using resistivity cone was expected very effective.

Laboratory experiments for the removal efficiency of heavy metals in land application of sludge, the accumulation and translocation of heavy metals in x plants after transplanting, and the responses of Minari growth with different ratio of land application of sludge were conducted to determine the potential ability of bioremediation with Minari plants. The removal rate and translocation of copper. zinc. lead. and cadmium in soil and plants were compared after transplanting the Minari plants to soil treated with different ratio of sludge. The removal efficiency of heavy metals in soil incorporated with sludge was different with application ratio, but increased with growing periods of Minari plants. The removal efficiency of Cu, Zn, Pb, and Cd ranged from 67 to 74% from 51% to 63%, from 37% to 71%. and from 15% to 25% after 45 days of transplanting. respectively. The amount removed the copper value. 65.9 mg/kg, observed to be highest in soil incorporated 3% sludge after 45 days. The translocation of Cu. Zn. Pb. and Cd from shoots to roots ranged from 18 to 53%, from 17 to 32%, from 14 to 49%, and from 23 to 38% over growing periods. respectively. In plant responses it appeared to be inhibited the plant growth in the treatment compared with the control at early stage of growth. However, the fresh weights of Minari plant increased from 12.5 to 62.5% in the sludge application after 45 days relative to the control. Therefore the Minari might play a useful role in bioremediation of Cu, Zn, Pb, and Cd in the land application of sludge.
