  • This study was performed in Seolmacheon basin to evaluate the adequacy of GLDAS (Global Land Data Assimilation System) and GLEAM (Global Land Evaporation Amsterdam Model) evapotranspiration data. The verification data necessary for the evaluation of adequacy were calculated after processing the latent heat flux data produced in the Seolmacheon basin with the Koflux program. In order to gap-fill the empty period, alternative evapotranspiration was calculated in three ways: FAO-PM (Food and Agriculture Organization-Penman Monteith), MDV (Mean Diurnal Variation) and Kalman Filter. This study selected Kalman Filter method as the data gap-filling method because it showed the best Bias and RMSE among the three methods. The amount of GLDAS spatial evapotranspiration was calculated as Noah (version 2.1) with a time interval of 3 hours and a spatial resolution of 0.25°. The amount of GLEAM spatial evapotranspiration was calculated using GLEAM (version 3.1a). This study evaluated the spatial evapotranspiration of GLDAS and GLEAM as the evapotranspiration based on eddy covariance. As a result of evaluation, GLDAS spatial evapotranspiration showed better results than GLEAM. Accordingly, in this study, the GLDAS method was proposed as a method for calculating the amount of spatial evapotranspiration in the Seolmacheon basin.

  • Short implants are used in parts which have anatomical structures like maxillary sinus, inferior alveolar nerve and limited alveolar height due to severe alveolar bone resorption. In these case, there are no need of additional bone augmentation so there are advantages like reduced entire treatment time, reduced patient's discomfort and protection of important anatomical structures. The aim of this study is, in implants whose length is less than 10mm, to analyze the impact of implant length, diameter, location of implant placement, presence of bone graft, presence of prosthesis splinting on survival rates and marginal bone resorption. The samples used in this study were 227 implants, less than 10mm, placed in 137 patients in Wonkwang university dental hospital implant center. From dental charts the information about implant length, diameter, location of implant placement, presence of bone graft, presence of prosthesis splinting were obtained. Emago advanced v5.6(Oral diagnostic systems, Amsterdam, The Netherlands)program was used to measure the amount of marginal bone resorption. Out of total 227 implants, resulting in 96.5 % of survival rate. There was a tendency toward higher failure rates for the maxilla and bone graft site. No significant difference in marginal bone resorption was found associated with length of implants(p>0.05) and neither with the diameter of implants. Among the risk factors examined, more failure rates of short implants can be attributed to poor bone quality in the maxilla and presence of bone graft. At implants under 10mm, length, diameter, location of implant placement, bone graft and splinting of prosthesis didn't affect marginal bone loss.

  • In this study, the actual evapotranspiration products of Global Land Data Assimilation System (GLDAS), Global Land Evaporation Amsterdam Model (GLEAM) and MOD16, which are satellite- and reanalysis-based dataset, were validated at the flux tower sites (i.e., CFK and SMK) managed by Korea Institute of Hydrological Survey, and the uncertainty and correlation analysis were conducted using Triple Collocation (TC) method. The result of validation with the flux tower showed better agreement in the order of GLEAM> GLDAS>MOD16. At the result of three combinations (S1: flux tower vs. GLDAS vs. MOD16, S2: flux tower vs. GLDAS vs. GLEAM, S3: flux tower vs. GLEAM vs. MOD16), the order of best to worst is GLEAM, GLDAS, MOD16, and flux tower for CFK (GLDAS> GLEAM>MOD16>flux tower for SMK). Since the error variance and correlation coefficients of the flux tower show relatively worse performance in TC analysis than the other products, By applying TC method to three products (GLDAS vs. GLEAM vs. MOD16), the uncertainty of each dataset were evaluated at the Korean Peninsula, As a results, the GLDAS and GLEAM performed reasonable performance (low error variance and high correlation coefficient), whereas results of MOD16 showed high error variance and low correlation coefficient at the cropland.

  • Most environmental impact assessment(EIA) programs around the world require the consideration of human health impacts. Yet relatively few EIA documents adequately address those impacts. This article examines how, why, and to what extent health impacts are analyzed in environmental impact assessments. This article investigates these problems and provides recommendations to improve human health impact assessment(HIA), using methods, procedures and case study. Also, a comprehensive approach for the evaluation of possible health effects in an EIA is described, illustrated with the example of Amsterdam Airport Schiphol. Unlike many EIAs, we estimated quantitatively the impact of aircraft-related pollution in terms of the number of affected people for aircraft noise annoyance, odour annoyance and hypertension. In addition, an analysis of health registry data on cardiovascular and respiratory diseases and a short survey on annoyance and risk perception were carried out.

  • The purpose of this study was to analyze the planning characteristics and it's application of container architecture as case study. Field survey was used to analyze the spatial planning characteristics in terms of development outline, appearance, exterior, floor plan and interior of eight famous cases in Berlin, Hamburg, Hannover, Amsterdam and Paris of Europe. The results of this study were as follows; Firstly, good examples of container architectures such as student housing, social service center, temporary medical facility and cruise terminal in Europe suggested the potential of domestic applicability in various purposes and development. Secondly, various types of freight container, building container and module frame system should be developed with their reprocessing environment. Thirdly, it is necessary for us to develop ISO type(20~40ft) container and standard plan with interior and storage design reflecting demands of residents. Finally, the use of container module will be an environmental-friendly alternative for its modularity and reusability, so it should be used as it is without severe deformation. The development of environmental friendly energy sources such as hydro and solar power is necessary for domestic container architecture as well. The container design should include the use of high quality of exterior finishing materials and the plan of aesthetical color planning to make the building a local landmark.

  • This research is an effort to clarify the causes associated with the 'failure' of public housing projects built in the 20th century. Two of the most brutal symbol of failure were selected: the Pruitt-Igoe built in St. Louis, U.S.A. and the Bijlmermeer in the south of Amsterdam, Netherlands. Many critics have attributed the problems of the selected housing projects to architectural failure, and proposed a series of new approaches to architectural design. The claim that many housing projects 'failed' because they were based on an agenda for social reform, derived from the ideas of the CIAM, presupposes that architects were in the position of authority over providing housing for the poor. This research tries to overturn the belief of architectural community which has placed the responsibility for the failure of public housing on designers. The sense of isolation and powerlessness felt by the residents, and the social problems attendant on those feelings, may be reinforced by design but is not caused by Modern Architecture. It should be stressed that the political-economic and social context is more significant than the architectural design for the failure of public housing projects such as the Pruitt-Igoe and the Bijlmermeer.

  • For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

  • In the post-war period, the mass provision of social rental housing units represented the primary means for resolving housing welfare issues across much of Western Europe. In contrast to North America, large swathes of state subsidized rental housing where built and let-out at submarket rents, both to needy as well as regular working households. By the 1980s social housing accounted for as many as four in ten homes in some contexts. Since then however, these important welfare sectors have been under attack. On the one hand, privatization policies have continued to undermine the basis of social renting with home ownership and private rental sectors advanced by policy as preferable alternatives. On the other hand, social housing providers have been restructured in order to play a more residual role in the housing market and serve more targeted groups of socially vulnerable people. This paper assesses key differences in the development of West European social housing sectors as well as recent transformations in their status that represent a challenge their sustainability. It also looks to what insights this provides for the South Korean housing context where public housing has proliferated and been increasingly diversified in recent years.

  • This research is to find out the characteristics and significance of the plastic experiments with colored planes in Theo van Doesburg's works. Based on the analysis, the following results have been obtained. First, Thea van Doesburg's plastic experiments with colored planes started from the paintings in 1916-1918. series and series were made of the ion of still life or human motion. These paintings were intended to make effects of rhythm, acceleration and simultaneity. Second, he colored the outer and inner architectural surface with primary colors. The expression of visual. rhythm on the color design for De Vonk, Districts Housing Projects VIII & IX in Spangen, Multi-Housing in Oosterstraat, Friesian Housing, Landbouw Winter School, and University Hall in Amsterdam embodied the concept of painting-in-architecture. Third, the field of these experiments were extended into the architectural space. As a results, $H\hat{o}tel$ Particulier and Maison d'Artiste was shown on the Architectural Exhibition in Paris in 1923. The colored planes were used as a construction material. They generated the dynamic space in architecture. Fourth, through the pictorial works like Architectural Analysis, Contra-Composition, Simultaneous Composition or Simultaneous Contra-Composition, Tesseract and Aubette Cinema-Dancing Hall, he created the concepts of simultaneous integration including nature and the environments as well as space-time in the architecture.
