This study analyzes the perception survey of the general public on the problems of a neologism(new words), which are frequently used in media media, and derives improvement measures and implications based on the data. In general, it can be seen that the creed is exposed and used indiscriminately through media, and those in their 20s and 30s are positive for the use of new words and those in their 50s and 60s are relatively negative. The biggest problem is that excessive use of creed can cause conflict and alienation between generations, and the need for correct Korean use is recognized overall as it can enhance Hangeul destruction and inappropriate social awareness. However, media outlets often use new words in a positive way to induce interest and enrich content by using them in the right place for the latest trends, such as small but certain happiness. As an alternative to this problem, self-purification of media workers is the most important, and it is recommended to encourage proper use of Korean through media literacy education and campaigns.

Since the middle of the 1960's, revitalization of the media art has showed a new paradigm shift as a alternative to existing art genre. According to advances in technology the form of art becomes various. Nowdays, art work which is mixed with media and other genre is popular because of hybrid culture. The image medium has flexibilty to incorporate with other genre because of medium character. The media installation that applied the image medium means to mixed work of sculpture and media. The sculpture and media has been broadened the field through the media installation. this study discuss art works projected image on sculpture among various media installation works. The materiality of the sculpture and the vision of the image mix up each other. It is associated with M. Merleau-Ponty's sens theory.

Large amount of sludge have been generating in the process of water and wastewater treatment in urban area, and it has been making many environmental problems. Currently almost of sludge is landfilled, and since sludge is difficult to handle and dehydrate, the permeated water from the filled-in ground contaminate the surrounding soil and groundwater which may cause serious environmental and sociological problems. The organic component in sludge can be almost removed through the heat treatment process, and the final product is called artificial soil or artificial media according to the temperature control. To produce artificial media using sludge, chabazite and lime were used as an additive, and the mixture of sludge & additives was thermally treated in the firing kiln at about 800~1, 100。C for about fifteen minutes. The physical and chemical characteristics of the produced artificial media were analyzed, and it showed that it can be used as an artificial media for plant production or soil conditioner for farmland. The concentrations of the toxic heavy metals in the artificial media were lower than the soil quality standard for farmland. The characteristics of produced artificial media, using the mixture of sludge and additives through the heat treatment, is similar to the natural chabazite and soil. The analyzed result of the mineral composition of artificial media showed that it has a characteristics similar to natural stable soil, so the produced artificial media may be applied to farmland or water culture without causing adverse effect. Therefore this study showed that the above process can be a feasible alternative for sludge treatment.

The major substrates used in soilless growing media are peat moss and perlite, where peat moss is a limited and expensive natural resource. Determination of appropriate substrates based on technical and economic feasibility is the vital aspect of research and the key to success in any soilless production system. This research work was performed to evaluate different low-cost and sustainable alternative substrate as soilless growing media for horticulture plant. The objective of this study was to compare the effect of sawdust species and steam treatment, for physico-chemical properties and growth of horticultural plant. This study involves the physical and chemical characterization and growth test of four substrate (pine sawdust, oak sawdust, steamed pine sawdust and steamed oak sawdust) in order to evaluate their use as components of growing media. Steamed oak sawdust ($121^{\circ}C$, 30 min) showed adequate physical and chemical properties compared to peat moss for their use as growing media. The growing media were prepared using different mixture proportion to grow Brassica campestris L., Festuca arundinacea and Lespedeza cyrtobotrya Miq. The highest germination, stem length and leaf area of Brassica campestris L., Festuca arundinacea and Lespedeza cyrtobotrya were observed in 30 minute steamed oak sawdust mixture growing media. The steam treatment condition of sawdust used in the growing media significantly positive affected the germination, the stem length and the leaf area.

It is said that the highlight in the media covergence and integration within digital environment era is 'Contents'. Due to the advent of new media and various covergence and integration services, the competition between the platforms has become aggressive. As a result, it is predicted that the negotiation power of a 'Content's industry will be strengthened. In reality, the actual environmental changes in the media environment have accompanied elements of industrial crisis rather than opportunity to expand the market. The changes are especially causing sales structure distortion and proceeds deterioration in the Korean film industry. Moreover, telecommunication and broadcasting businesses are making their entrance into the film industry, through the appearance of the media covergence and integration as a backdrop. Thus, the situation that the Korean film industry is facing is closely associated with the development of the digital technology and new media environment. Eventually, weathering the crisis and pioneering the future will be possible through changes in the media environment. The purpose of this study is to show how the media covergence and integration phenomenon is occurring in the film industry. This study will also focus on what new problems are occurring as a result, and seek out the solutions that are available.

멀티미디어 시스템에서 수행되는 부하 중 상당 부분은 정해진 시간에 주기적으로 수행되어 연속 매체(continuous media)를 처리하는 주기 태스크들이다. 연속 매체들을 처리하는 두 주기 태스크의 수행 요청 시간(release time)간에 인공적인 위상(phase)을 줄 경우, 전체 부하의 처리 타이밍에 영향을 주게 되며, 특히, 적절한 위상을 부여할 경우 부하가 고르게 분산된다. 부하의 고른 분산은 태스크 간섭을 줄여 지터(jitter), 종료시한 초과(deadline miss), 그리고 긴 응답 시간(response time) 등의 문제를 해소시킨다. 본 논문에서는 새로운 위상 스케줄링(phased scheduling) 알고리즘 및 알고리즘을 개발하고 평가할 수 있는 실험 환경을 제안한다. 본 논문에 제시된 알고리즘은 저자들의 선행 논문 1 에서 제시한 알고리즘의 대안이다. 새로운 알고리즘은 정확하게 최적의 위상을 찾지는 않으나 기존 알고리즘보다 빠르게 수행되며 적용 범위가 넓다.Abstract A multimedia system consists of substantial amount of continuous media workload scheduled periodically at deterministic time points. Artificial phase between the invocation times of any two continuous media tasks affects the timing of the entire workload. A proper phase configuration distributes workload uniformly over time and reduces task interference that may otherwise result in jitter, deadline miss, and long response time. The objective of this paper is to work out a phased scheduling algorithm and to evaluate its effectiveness. The algorithm in this paper is an alternative approach to our previous work 1 . It is almost as accurate as the predecessor but two of three times faster in identifying the appropriate phase vector.

The purpose of this study was to investigate coverage patterns of the Korean internet news media on 'US-Iraq War' and its meaning and discourse structure. The internet news media was recently established and become a popular news media to compete with old news media in Korea. The author selected the 'Oh My News' as a representative internet news media for his analysis, and collected its news items from Mar. 20, 2003 to Dec. 17, 2003. on the basis of 4 different phases of the war. He analysed the whole of news items with various semiotic and discourse analytic methods, especially applying for Bell's concepts of time and discourse structure. As a result of this study, first of all, it was found that the 'Oh My News' tended to cover this war so different ways as the old news media did. It did not pay attention to the procedure of war, especially, battlefields, fighting between US and Iraq, damages and casualties. But, instead, it paid attention to many doubts about intention of US government and the President, Bush, dichotomous shift between pro-America and anti-America, rightness of dispatching Korean army into Iraq, etc. Secondly, it functioned as a kind of alternative media to speak up different voices comparing with those of old media. It tended to suggest different perspectives and opinions, while the old media tended to follow American perspectives and opinions. Thirdly, it became as a kind of new media setting agendas for this war in Korean society. It played a very important role for setting agendas for various issues related with this war. In conclusion, the internet news media has recently become a kind of new news media for suggesting alternative or different opinions, setting agendas, initiating discourses, etc., even though it still has may problems of becoming so called orthodox news media.

This study is focused on the relationship of old and new media with the concept of cultural interface. This study try to find out their similarities and differences of media contents and interface through contents analysis of text. As a results, there are competible coexistance of transparent immediacy and hypermediacy as a double logic of remediation. And the features of remediation that borrowing, aggressive, and absorb are showed cross each other. A related studies are focused on the narrative structure of story and on analysis of character, events, and background. And the other studies are focused on the policy of new media distribution. But, recent new media emphasizes the visualization of 3D technology and that strategy. Also they tries to convert a various media contents. Therefore, it is important to check and prepare those environmental changes of media. Then, more researches will be applied to remediation and cultural interface of this study. And I hope that they will be find an alternative strategy of contents and interface on media.
