Soil quality standards (SQS) are necessary to protect the human health and soil biota from the exposure to soil pollutants. The current SQS in Korea contain only sixteen substances, and it is scheduled to expand the number of substances. Chemical ranking and scoring (CRS) system is very effective to screen the priority chemicals for the future SQS in terms of their toxicity and exposure potential. In this study, several CRS systems were extensively compared to propose the assessment factors that required for the screening of soil pollutants The CRS systems considered in this study include the CHEMS-1 (Chemical Hazard Evaluation for Management Strategies), SCRAM (Scoring and Ranking Assessment Model), EURAM (European Union Risk Ranking Method), ARET (Accelerated Reduction/Elimination of Toxics), CRSKorea, and other systems. The additional assessment factors of CRS suitable for soil pollutants were suggested. We suggest soil adsorption factor as an appropriate factor of CRS system to consider chemical transport from soil to groundwater. Other factors such as soil emission rate and cases of accident of soil pollutants were included. These results were reflected to screen the priority chemicals in Korea, as a part of the project entitled ‘Setting the Priority of Soil Contaminants'.

The purpose of this research is to scrutinize what are characteristics of client-identified significant events and interactional process in Gestalt therapy using the therapeutic media. The subjects of the study were 4 participants. To this purpose, a audio-taped session and a intensive interview were conducted to examine. The collected data for this study were analyzed by Comprehensive Process Analysis. The audio-taped session and interview data were first transcribed and then analyzed for client-identified significant events. A total of 74 pairs of conversations were analyzed to derive the interactional process within the significant event case. In conclusion, it was found that the interactional process of significant events in the Gestalt therapy contributed to the change of the client by interacting with the therapeutic media. 5 major themes of interaction with the therapeutic madia appeared. The 5 major themes are allowance, identification, recognition, acceptance and prospective. Finally, the significance and limitations of the study were clarified and suggested for further study.

This study was performed the real motion and DEM simulation of ball motion using three different types of grinding media with different size and materials in media formation for optimization of process conditions in a traditional ball mill (media ball mill). In the simulation, the rotational speed of the mill, the material of the medium, the velocity of the medium, and the coefficient of friction between the media and the wall of pot were fixed into the actual experimental conditions. The motion of various kinds of grinding media was quantitatively measured by setting the grinding zone defined in the present study on the photographs taken and the snapshot images analyzed in the simulation. In addition, we observed the quantitatively measured value and the changed morphology of the sample and examined the correlation. Therefore, it is suggested to optimize the grinding media which has the greatest influence on the grinding zone under specific experimental conditions.

Emerging service classes need an error model which efficiently satisfies the requirements for each media and application. However limited flexibility in the error control has been provided. Therefore we propose a new error control model which applies error control scheme per media flexibly with respect to ETL(Error Tolerance Leverl) and delay. In order to select the error control scheme in this model, the attributes of media(i.e., ETL, isochronism), the attributes of application(i.e., delay) and environment parameters(i.e., packet loss ration, network types, connection modes of the application) are considered as effect factors.

DRASTIC system developed by U.S.EPA, is widely used for assessing regional groundwater pollution susceptibility by using hydrogeological factors such as depth to water, net recharge, aquifer media, soil media, topography, vadose zone media, hydraulic conductivity. The system can be applied to site selection of well or waste disposal and landuse for groundwater protection. In this study, hydrogeological spatial database of Younggwang area about topography, drainage, well, geology, soil and landuse was constructed using GIS (Geographic Information System) and regional groundwater pollution susceptibility is analyzed using the spatial database and GIS overlay technique.

Human beings have been leading their life and desirable social life through communication. Human communication has been changed and expanded through language, letters, printing media, broadcasting media, and more recently network communication media. Since the invention of characters, books have been the human beings' communication medium that have the longest history, and they have preserved and succeeded human spiritual world. Children's picture books are also a communication medium composed of the transmitter of the information, message, medium, and the receiver, and makes the process of communication. The sender: writer, illustrator, and editor, analyzes children, special receiver, symbolizes messages, make up contents and make communication come true by selecting media and effectively delivering them to children. Considering the developmental characteristics of the receiver, children and their desires, visual media such as the writings and illustrations. The writings and illustrations are the most appropriate for communication with children. The first, picture books are for the communication between grown-ups and children, and also that with society for helping children find their identity and perform their roles. The second, through the message of writings and illustrations young children acquire human communication ability of this age. That is, they experience and learn visual communication and letter communication

In the multimedia era and contemporary art, the expression of narrative is expanding in various ways based on formal theory. And the expression form is maximized according to the use of each medium. In terms of understanding artworks, an approach that combines various expressions and media using these narratives is also possible. Therefore, this study analyzed the works of the artists by selecting three artists, Sadic Guissi Alfrazi, Lindsay Sears, and Kara Walker, who fused the media using narrative structures. Through this, it was intended to present the artistic value and significance of the work and the possibility of expanding the narrative expression of contemporary art in the future. As a result of the analysis of previous artists' works, it was shown that the phase of convergence can be derived by using the medium of narrative concepts beyond the dichotomy of content and form, confirming that digital technology and media development are changing the form of art. In addition, it was confirmed that the use of narrative structure facilitates media conversion. It is expected that discussions on the new paradigm of contemporary art will progress in the future.
