본 연구는 오픈 소스 플랫폼인 아두이노를 결합한 센서 기반 미디어 설치 제작에서의 인터랙션 설계 유형에 대한 것이다. 구현한 미디어 설치 작품들을 유형화하여 센서기반의 미디어아트 표현 방식의 다양성과 그 의미를 모색하고자 한다. 미디어 아트의 상호작용 방식에 대한 이해를 바탕으로 센서를 이용한 미디어 설치 제작에서의 인터랙션 설계 유형을 모터 제어를 통한 물리적 움직임, 초음파 센서와 모터을 활용한 '인공식물, 빛, 사운드 센서 활용한 '가상정원', 기울기 센서를 통한 무빙이미지, 4가지로 분류한다. 이를 통해 미디어 소프트웨어가 작업에 적합한 기술로 선택할 수 있고 다양한 표현으로 진화하고 있는 예술 표현의 사례로 제시될 수 있을 것으로 본다.

This study proposes an approach to Product Data Management (PDM) education for collaborative product data management, which can support collaborative product development process. This approach introduces social media and a PDM system into a framework for PDM education supported by consistent product development process and product data model. It has been applied to two PDM classes and the result shows that the social media in PDM education can support not only experiences of the collaborative product data management but also interactive and informal communications among instructors and participants using integrated social media with product data during courses.

This study was conducted to use oyster shell as media for biological wastewater treatment. The comparison between the removal efficiencies of the activated sludge and the submerged biofilm process with oyster shell media (5% of reactor volume) for domestic sewage treatment was made. The contaminant removal efficiencies of the submerged process were higher than that of the activated sludge process. And the removal efficiencies of the submerged biofilm process with oyster shell media of 10% and 18% were Investigated at various loading rate. The removal efficiencies of 10% were higher than that of the 18% during the experimental period. The effluent concentration from the sub- merged bloom process using oyster shell media was prediceted by the Stover-Kincannon model.

According to developing digital media, the delivery and the collection of information are changing with a variety of ways. Especially, digital, as it is, is easy for its sound, video and letter to be mixed. Therefore, media character, Audio-Visual will appear in total. Hypertext must be a basic form in the traveling way of media information which includes such digital Quality in originality. Taking advantage of digital media trait of hypertext , most users can make a research on a variety of studying method. On this thesis, a style of made-up hypertext is taking a part of recent digital culture, and I want to present a different method in research, using two hypertext skills, adventurous choice and joint origination

Recently, media platforms such as YouTube and Twitch provide services that can generate personal revenue by utilizing media content produced by individuals. In this regard, interest in the copyright of media content is increasing. In particular, in the case of an audio source, competition for securing audio source copyright is fierce because it is an essential element for almost all media content production. In this paper, we propose a method to store the audio source and its signature using a blockchain and distributed storage system to verify the copyright of music content. To identify the possibility of extracting the audio signature of the audio source and to include it as blockchain transaction data, we implement the audio source and its signature file upload system based on the proposed scheme. In addition, we show the effectiveness of the proposed method through experiments on uploading and retrieving audio files and identify future improvements.

5G-based HMD technology grew rapidly in the context of the environment change of convergence technology media and mobile networks in the fourth industrial era. It has also grown into a core technology that transforms our digital visual system. However, there is no research or system that can understand and verify radical visual system changes. Therefore, it is necessary to have an engineering understanding and verification of the diffusion of HMD media imaging devices. Beyond the distinction between virtual and real, research is urgently needed on the new three-dimensional interface of the 21st century through viewer participation. For this reason, research on the algorithm structure of interactive video media using L-System is an essential process and will be a guide to understanding the virtual reality interactive environment.

A porous medium is composed of solids, fluids, and gas which have different physical and chemical properties. In addition, these constituents have a relative velocity between each other. So far, in order to analyze porous media using finite element method, Lagrangian or Eulerian method has been used. However, the numerical analyses for porous media have a defect that the methods do not describe the movements of constituents. In this paper, numerical analysis for unsaturated porous media was performed in frame of ALE method which has advantages of Lagrangian and Eulerian. Namely, the Lagrangian description was used in solid phase, and the Eulerian description was used in fluid or gas phase in a porous medium Then the relationship between each other was controlled by the convective term in ALE method. Finally, the numerical results of ALE were compared with tile results of Lagrangian analysis.

In Korea, almost every water treatment plant suffers from seasonal problem of algae and turbidity which result from eutrophication and heavy rainfall. To relieve this problem, experimental investigation was performed to study the applicability of a floating-media and sand filter to preliminary water treatment in terms of algae and turbidity removal. Experimental results using pure-cultured algae influent showed that the shape of algae species as well as filtration velocity affects the removal efficiency. From the experiments using natural river water, it was concluded that algae removal is more sensitive to floating-media depth but turbidity more sensitive to sand depth. As the filtration velocity increased, the removal of turbidity decreased but that of algae was not affected. The floating-media and sand filter removed more than 30 % of TP, TN, turbidity, Chl-a and CODcr, and less than 20 % of DOC and $UV_{254}$.

The purpose of this study is to suggest the design by using digital media the general hospital. The important result and advantage of the study are as follows; At first, applicability and maintenance of form and function design are enhanced and the digital media could be used for development of better and economical design. Secondly, the 3D CAD system useful for communication media and instructional tool for hospital planners and designers. Thirdly, fast and economical evaluation are obtained through the study of experimental simulation. Finally as a new tool in architectural field, the system helps to enhance the relationship between digital media and human. New concept and tools of hospital design are being developed in terms of its function, environment, and psychology. The computational design system should be improved for user friendly in the future.

Particulate contamination is known to be a significant cause of failures of removable storage media. In this work, the effect of particles on the surface damage of removable hard disk media was investigated. The particles of different materials and size were introduced to the Head Disk Interface (HDI) using a particle injection system. It was round that the particles of particulate size and property serious damaged the media. This study showed that cleaning pad is effective for reducing particle contamination, except fer the particles of specific size and property. As a means to remove the particles of specific sire. the concept of using a stepped taper at the leading edge of the slider is proposed.
