In contemporary architecture, there are developing aspects of variety design in material, image and form. These various architectural trends even change classical media and this concept is based on the background of current idea - digital, information-media, imagination with paradigm. So this study aims to show the present status of the expressions in the contemporary architecture of Korea under its media situation. Namely usual thoughts for design have to be changed because our life is surrounded by many kinds of powerful media signs and various mixed cultural circumstances. And like this, we know for study about the relation between media and current architecture, still more Korean present condition. In chapter one, the background, purpose and method of study are explained. In chapter two, the general concept of media is inquired in this study. In the process of searching for the formingbasic background, the characteristic of this study is understood. In chapter three, this study inquires the aspect of media expression in modern architecture. In chapter four, according to chapter three, this study shows the present status of media expressions in the contemporary architecture of Korea. In chapter five, a synthetic conclusion is presented.

Sand filter is a key unit process for particle removal in water purification treatments. Its long-standing use is due to on-site customized retrofit. Proper selection of filter media is one of the retrofit approaches to improve filter performance. This study described a series of controlled laboratory column tests and examined the effects of media property on filtration and backwash. When sand media of 0.51 mm in effective size was replaced by sand of 0.60 mm, the filter run increased up to 5 times in the given bed depth. The change of media property required an increase of backwash rate by 0.05 m/min to satisfy the requirement of bed expansion, more than 20%. When the anthracite was changed with lower effective size and uniformity coefficient, correlation with sand in the filter bed could be satisfied within the permissible error between media and bulk characteristics. Besides, this selection resulted in a well-stratified configuration of media layers after bed expansion. The column study showed that the correlation of property between the dual media had a significant effect on the filter productivity and backwash interval.

Objective: Density gradient centrifugation (DGC) is frequently used to isolate high-motility fractions of spermatozoa. We compared the efficacy of four DGC media in terms of the percentage of morphologically normal spermatozoa, DNA fragmentation level, and hyaluronic acid (HA) binding ability. Methods: Thirty men with a total motile spermatozoa count > 80 million participated. Semen samples were divided into four aliquots, which were processed using PureSperm, PureCeption, Sidney, and SpermGrad media, respectively. The DNA fragmentation level was measured using the Halosperm assay kit and HA binding ability was measured using the HBA assay kit. Results: The mean percentage of morphologically normal spermatozoa was significantly enhanced after DGC using all four media (10.3%, 9.9%, 9.8%, and 10.7%, respectively; p< 0.05 for each when compared with 6.9% in raw semen). The DNA fragmentation level was significantly reduced after DGC using PureSperm, PureCeption, and SpermGrad media (6.0%, 6.5%, and 4.9%, respectively; p< 0.05 for each when compared with 11.2% in raw semen), but not after DGC using Sidney media (8.5%, p> 0.05). HA binding ability did not change after DGC using any of the four media. Conclusion: The four media were equally effective for obtaining a sperm fraction with highly motile, morphologically normal sperm. PureSperm, PureCeption, and SpermGrad media were equally effective for acquiring a sperm fraction with less DNA fragmentation.

The aims of this study is to examine the effects of the changes in HRT(Hydraulic Retention Time) and media charge in a water-mill, among other operation factors, on the nitrogen and phosphorus removal in order to use up-flow anaerobic reactors, anoxic reactors and water-mill aerobic reactors for sewage treatment. The extension of HRT improved the nitrogen removal efficiency, however the removal pattern was constant regardless of HRT. The removal of phosphorus was constant (80%-90%) regardless of the change in HRT. The removal rate with change in influx load varied such that at the OLR (Organic Load Rate) of 1-3 kg/d, the T-N removal efficiency was 80.7%-88.9% and the T-P removal efficiency was 82.9%-89.3% while at the NLR (Nitrogen Loading Rate) of 0.108-0.156 kg/d the removal efficiencies were 80.7-88.9% (T-N) and 82.9-89.3% (T-P). The analyses of the nitrogen and phosphorous removal characteristics with the C/N and C/P ratio showed that the mean T-N removal rate was 88% at the C/N ratio of 1.2-2.6, and that the mean T-P removal rate was 86% at the C/P ratio of 7.2-14.1. Also, the analysis of nitrogen and phosphorous removal characteristics were analyzed in relation to media charge. The comparison between with and without media charge in the water-mill showed that while the nitrogen removal efficiencies were 86-94% and 85-89% respectively, the difference of phosphorous removal efficiencies were between the two conditions was not significant, thus it suggested that the media charge has less effect on the removal efficiency of phosphorous compared to that of nitrogen.

It has been 10 years since KBS first broadcasted TV program for the purpose of expanding mutual criticism among Korean mass media. This study conducted a content analysis of KBS episodes for the last 10 years. Through the content analysis, this study explored what the program had showed us in the aspects of 'the subject of criticism', 'the ground of criticism', 'the attribution of criticism'. The content analysis could show meaningful results to the study of media criticism, because it not only provides a meta-analysis of the problems Korean mass media have had for the last 10 years but also examines the program has been consistent in the regard of criticism fairness. The result of this study showed that has pointed out the practices of unfairness, political bias and superficial and shallow reporting as the most critical problems the Korean mass media have. Also, the result showed that had not been consistent in the regards of 'the subject of criticism', 'the ground of criticism', 'the attribution of criticism'. While the program mostly focused on the problems of political bias and unfairness in the early stage, the focus of criticism moved to the problems of sensationalism and superficial reporting laster. This study discussed that the change of criticism might have a relation with the change of KBS governance.

The purpose of this study is to explore the changing trajectory of using educational media through longitudinal data analysis. We categorize the feature of using educational media as usage for learning, usage for information, and usage for the game. We explore the longitudinal changing patterns of usage for learning, usage for information, and usage for the game by LGM(Longitudinal Growth Modeling). We also find the gender difference between these longitudinal changing trajectories. We used 3,499 samples of KYPS middle school second-grade panel data. We found these results: (a) Both usage for learning and information are statically significant variability in initial level and rate of change. Both of the changing trajectories have increased. (b) Girls have a higher rate of the change both in the usage of learning and information than boys over time. (c) There is a statistically significant individual variability in initial levels and rate of change in the usage of the game over time. (d) Boys have a higher rate of initial value than girls in the usage of games, but there is no significant difference in the rate of changing trajectories.

While shifting from modern society to post-industrial society, social structure is changing from the period which pursues material affluence to that which pursues psychological abundance. Formation of various values along with pursuit of psychological abundance has made the illusion of standardization, massification, and popularization meaningless. Different from functionality oriented approach in the past, today's design requires diversified, multiple and integrated thinking and way in fast-changing social phenomena and stream, and lets human loose from the restriction of time and space thanks to technological development. It appears as new and various attempts along with paradigm shift of the wholle society, however the existing physical and actual things gradually transit to non-physical and non-actual things. Tendency of dematerialization has spread as far as esthetic and environmental genre on the basis of social and philosophical base along with change of consumption culture, and has displayed complex and de-genre aspect. Paradigm shift has expanded the range of communication by changing to user's independent awareness and sensitive concept, among them, light displays various changes of space by taking the role of new medium. Particularly, the light as the media expression beyond the phenomenon of light of traditional concept acts as an essential element to stimulate sensitivity and for experience as an immaterial element which shows this change of space most dramatically. This research aimed at recognizing space in complex dimension, exploring the relation between the light and space through media expression displayed in the realization of immateriality, expanding the meaning of light, and recognizing it as the possibility of creative and future-oriented light space creation which responds to technological development and social change.

Typography, as the median for communication, has expanded its roles according the attributes of the media where it Is used, and the change of media follwing the change of times is presenting new directions to the field of typography. The attempts of 20C experimental typography prioritize visual formativeness, free typography and language started to appear on printed matters and different kinds of prints put pep in magazines. Thus, experiments in the aspects of effective delivery of inpormation that letters have and aesthetic side of shapes of letter are continuing. Today with the appearance of multimedia, development of visual colture and rapid development of digital technology, the range of experimental typography has expanded even wider and therefore, different kinds of expressions became possible. As seen above, unlike the existing static printed media that carries linguistic information only, letters in the multimedia environment is shown in the movie titles, TV or web not only as a basic visual media such as type and image, but as a dynamic and complex factor that contains additional information of motion and sound factor. This study will attempt to find the historic context of focus of moment from the kinetic art and define the moving letters as kinetic typography. Therefore, this paper will have an understanding on kinetic typography's background, concept and characteristics following the change of communication environment in the multimedia era and tried to study the basic theories of kinetic typography and the information delivery and imagery function of letters. Also, this paper attempted to carry out a study on whether kinetic typography is delivering information smoothly from the aspect of communication through the image role as delivering information by studying major works of artists who have influenced kinetic typography. Based on this study, I would like to suggest new direction for effective delivery of information and value of use.
