The management of wastes within the urban landscape has become a critical concern to both local governments and inhabitants. With landfill capacities steadily decreasing, rapid growth of economy, population and urbanization, citizen awareness of the environment and public health problems occured by existing landfill sites make difficulties in selecting the landfill site. Therefore, this study has been performed to select the optimum waste landfill site using GSIS methodology to reduce the time, cost and effort. As the result of this study, we can investigate many factors synthetically which could not be handled by the former method using hands in the site selection for waste landfill, and we can carry out economically the work of selecting suitable site throughout the vast area.

Apartment design in residential Area is restricted by building distance limit code. Building distance limit decreases gradually to the 0.8H(height), and residential area has 250% site area ratio by building code, so site using has become efficient. In this study, examine the relationship between present building distance limit and right of daylighting environment by computer simulation. As well, high-rise residential officetel and multipurpose residential building becomes increase in commercial non-residential area. In the domestic, residential type multipurpose building made at the business area or central business area has 400∼800% site area ratio by building code. However, at a dweller's point of view, there are much lacks of environmental consideration to provide suitable daylighting environment. And, POE: Post Occupancy Evaluation is not completed yet. In this study, however, progress architectural environment prediction, basis by right of daylighting, and examine the possibility of daylighting by architectural distance limit code in residental area and by high-rise, high-density residential building in non-residental downtown area.

The usage of OPC-free alkali activated ground granulated blast furnace slag(GGBS) mortar has been widely studied on the previous years, due to its advantages on sustainability, durability and workability. This paper brings a new view, aiming to classify the best application in situ for each mortar, according to the type and activator content. By this practical implication, more efficiency is achieved on the construction site and consequently less waste of materials. In order to compare the different activators, the following experiments were performed: analysis of compressive strength at 28 days, setting time measured by needles penetration resistance, analysis of total pore volume performed by MIP and permeability assessment by RCPT test. In general, activated GGBS had acceptable performance in all cases compared to OPC, and remarkable improved durability. Following the experimental results, it was confirmed that each activator and different concentrations impose distinct outcome performance to the mortar which allows the classification. It was observed that the activator Ca(OH)2 is the most versatile among the others, even though it has limited compressive strength, being suitable for laying mortar, coating/plaster, adhesive and grouting mortar. Samples activated with NaOH, in turn, presented in general the most similar results compared to OPC.

For the efficient control of atmospheric quality, it is so important to predict the influence accurately of which the air pollutant emitted into the atmosphere. Atmospheric dispersion model enables to simulate and grasp the atmospheric condition occurred due to the emission of pollutants. The result of model is largely affected by the amount of emission, the characteristics of physical and chemical process, meteorological input data, and the receptor which the concentration is calculated. The aim of this research, therefore, is to suggest more suitable model in Pusan area than other areas by performing TCM2, CDM2.0 and ISCLT2 models. As the basic work for executing the model, we computed the amount of emission of air pollutants in Pusan at 1992 and analyzed the occurrence frequency of atmospheric stability for recent decade(1985~19941, CDM2.0 showed the similar result relatively with observed value in the case of full year(1992), fall and winter, and ISCLT2 brought more suitable result in spring for Pusan area. As the result of this research, in future, it is necessary for us to develop the numerical model considering the topographical characteristics, to select the proper observation site and to increase the observation site for Pusan.

Investigation of bedrock quality and the legal restriction for developing the aggregate resources were carried out with GIS in the Wondeung area Gokseong-gun, Jeollanam-do province. Firstly, we surveyed the exposed bedrocks in the field and examined in physical properties in the lab. Secondly we analyzed the legal restriction by using GIS based on bufferzone and viewshed analysis. At the results of this study, the area can be used totally as the crushed stones. However the suitability sites of crushed stone have various regulations. So the legal restriction is the principal standard to develop the crushed stone in the Wondeung area. Suitable site for crushed stones are about 30% in the Wondeung area.

The spiral case concrete (SCC) used in the underground powerhouse of large hydropower stations is complex, difficult to pour, and has high requirements for temperature control and crack prevention. In this study, based on the closed-loop control theory of "multi-source sensing, real analysis, and intelligent control", a new intelligent cooling control system (ICCS) suitable for the SCC is developed and is further applied to the Wudongde large-scale underground powerhouse. By employing the site monitoring data, numerical simulation, and field investigation, the temperature control quality of the SCC is evaluated. The results show that the target temperature control curve can be accurately tracked, and the temperature control indicators such as the maximum temperature can meet the design requirements by adopting the ICCS. Moreover, the numerical results and site investigation indicate that a safety factor of the spiral case structure was sure, and no cracking was found in the concrete blocks, by which the effectiveness of the system for improving the quality of temperature control of the SCC is verified. Finally, an intelligent cooling control procedure suitable for the SCC is proposed, which can provide a reference for improving the design and construction level for similar projects.

The objective of this study was to select appropriate sites for reforestation CDM using satellite image and spatial data in North Korea. A suitable site for reforestation CDM can be defined as non-forest area since 1990. To detect land cover change between two different years and to delineate potential reforestation CDM site(unstocked forest, converted crop land, denuded bare land), Landsat TM satellite image which was scanned in 1988 and SPOT Pan-sharpened image which was scanned in 2007 were used. As a result of classification, 1,214 ha of forest area in 1989 had been converted to other land cover types in 2007. and 2,245 ha of the total study area was detected to be suitable for reforestation CDM. 79.2% of total potential CDM sites was converted crop land. Through topography and accessibility analysis for potential reforestation CDM sites detected by satellite image, suitability index was calculated and the potential reforestation area was reclassified into suitability grades.

Today the company's brand sites are in tendency locating as a handy method to administrate company vision, value and image. So this study tried to examine the aspects of storytelling around Amore Pacific's brand site. To secure the discussion's centrality and concreteness, two issues are considered to be aimed in methodology. First, the menus of relevant site were examined to see if they are securing minimal narrative. This was an attempt to discuss the minimum narrativity that target text is supposed to possess, to objectify little more the term 'storytelling.' After considering the menus of relevant site through narratological ideas of Gerald Prince, the menus that satisfy the level of minimum narrative were hardly seen. Even 'OUR STORY', showing the intention of unraveling the vision and values within the company brand by stories, is not seemed to be reaching universal, objective storytelling. Second, pragmatic, reception theory were applied as another standard to judge storytelling possibilities of Amore Pacific's brand site. Roger C. Schank's script theory, being considered in the field of cognitive linguistics and cognitive psychology, became a handy tool for examining the interactions and its meaning between brand sites and its visitors. As a result, the relevant site could be seen as attempting storytelling following time sequence, through narrator kindly explaining 'visual image-event.' And it was conjecturable that, because of such function of narrator, visitors finishes storytelling in a personal shape by operating internal story based script. This study examined the level and methods of storytelling limited in online environment called as company brand site. But more studies are needed to be in progress, such as about the ways for company websites or brand sites to have an effective, continuous influence on potential consumers, narrator set-up ways suitable for character of subordinate menus, organizations of minimum narrative and so on.
