Stormwater runoff from urban road area as non-point source has a tendency of including lots of pollutants at initial rain period. Recently, there are several cases of having installed treatment facilities for reducing pollution discharge from the impervious cover in urban area to prevent watershed environment from getting worse. The filtration type among non-point source treatment systems has been known as one of the most efficient system for treatment of non-point source pollutants. Therefore, various kinds of filter media such as expanded polypropylene(EPP), granular activated carbon, zeolite, perlite, illite, sand, gravel has been developed. This study was conducted to verify performance and hydraulic characteristics of filter media as measures for non-point source. The experiment was carried out to evaluate applicability and variation of 4 kind of most popular filter media(EPP, GAC, Zeolite, Perlite) in headloss with elapsed time and influent flow rate and to obtain data base that could be used to establish management plan for road runoff treatment. In experiment by tap water, it showed that EPP and perlite those are floatable materials showed stable operating performance and lower headloss than the others.

The analysis used in this work was cost-benefit analysis method. All future costs and returns of a given mushroom house were discounted to the time of initial investment (present) by means of 3.5% discount rate. Then the cost of ownership was compared to the return from the system. This analysis method has been developed and coded into a balance sheet for use on a EXCEL program. Using this programmed analysis,a large number of the case studies were examined using different combinations of economic conditions. These results will be very useful to individuals considering investment in a mushroom house, or any similar production system. By the way of the sensitivity analysis for each important parameter, the change of the marginal cost-benefit period could be finally determined. These parameters were typically construction cost of mushroom house, cost of cooling system, required cooling and heating energy amounts, unit price of mushroom media bottle, growing number of media bottles, production weight per unit bottle, sale price of mushroom, and annual number of growing period, etc.

The concepts of geotourism and geoparks have emerged due to the paradigm shift in tourism and the increased recognition of geosites and geoheritage as legacies that must be protected and preserved. The number of geoparks designated by UNESCO and national governments is increasing globally. The purpose of this paper is to propose directions for enhancing Jeju Geopark to perform as a geological educational venue. This study reviewed the present conditions of the education and communication, the media, and the facilities of the geopark with respect to the required conditions to be effective for geological education. Data surveys, field surveys, visitor questionnaires, and interviews were conducted to examine the educational and guidance system of the geopark, the physical space configuration, and the operation and management methods. The research process is as follows. First, the study analyzed the status of the education and communication in Jeju Geopark, according to the criteria of the UNESCO GGN, using data acquired from the survey. Second, the study analyzed and evaluated the educational and communication facilities, and media, focusing on four aspects of the geopark: the geo-trail, spatial composition and layout, communicational and educational facilities, and the system and design of signboards. Third, the study assessed the perception and satisfaction of visitors to the geopark. Fourth, the study summarized the potential and limitations of the Jeju Geopark through in-depth interviews. The four analyses showed that enhancements in the exploration environment, communication, media, and operation and management system are all necessary for effective geological education. Based on these results, this study suggests directions for enhancing the geopark in the four following aspects. Management and maintenance must be improved to meet UNESCO criteria, while the improvements in the visiting environment quality, the supplementing of communication and facilities, and enhancements in the organization and system of operation and management also must be taken on.

This study interprets Cheong-gye-cheon restoration as a process of space production during expansion of capitalism, and performs discourse analysis in order to find out that how media discourse has been related to the production of Cheong-gye-cheon space in each period of historical changes. This paper is particularly concentrating on discovering regulation in discourse which connects people's experiences and perception towards certain ways in the relationship between newly producted space and media discourse. This paper construes the period of 1960s as a process which pre-modern bodies and facilities were changed into modern and urban 'daily life' by practicing a space which splitted in a concept of time efficiency. In 1980s, media represented the facilities which had been constructed at the Cheong-gye-cheon space as a 'disqualified facilities for a center of the city'. This is because, tertiary industries were emerged at the 'Gang-nam' in this period which widen the gap of finance between 'Gang-nam' and 'Gang-Buk'. The government wanted to redevelop this space in order to function accumulating capital efficiently. Therefore shop owners nearby Cheong-gye-cheon were forced to move out. The discourse, 'disqualified facilities for a center of the city', implicates this process. The media discourse in the 2000s produced the 'myth' through the 'signifier' such as artificially flowing water, fine scenery, historical but artificial structure and etc.. However, people can experience symbols of the artificial structures which leads people to the luxurious restaurants, coffee shops, and etc.. Naturally, the spectacles produced by media direct people to the homogeneous pattern of consume. This phenomena can be explained as a process which people practice, intentionally or non-intentionally, the capitalistic mode of production which changed from a period of production to a period of consumption.
