VOC(volatile organic compound)는 도료제조, 자동차, 선박의 도색, 인쇄, 염색 공정에서 주로 발생하는 휘발성 유기화합물로서 호흡기로 들어가면 중추신경 등 주요 기관의 장애를 일으킬 수 있으며, 질소화합물과 광화학반응을 일으켜 오존을 유발하는 위험물질이다. 정부에서는 1991년 대기환경보존법을 제정하여 유기용제의 배출을 규제하고 있고, 이 법에 따라 금년부터 석유화학정제업, 저유소에 VOC 방지시설을 의무적으로 설치해야 한다.(중략)

Photoimageable thick film technology is a new technology in that the lithography process such as exposure and development is applied to the conventional thick film process. Line resolution of 25 $\mu\textrm{m}$ width and 25 $\mu\textrm{m}$ space could be obtained by laminating green sheet, printing photoimageable Ag paste, exposing the test patterns, developing, and co-firing. In case of using the alumina substrate, 20 $\mu\textrm{m}$ fine line could be also obtained by similar process. Test results showed that exposing power density and developing time were the most important processing parameters for the fine line formation. Microstrip and series gap resonators with well-defined line morphology and good transmission characteristics in high frequency were formed by this new technology, and thereby dielectric constant and loss of test substrate were calculated.

This paper examines printed materials such as weekly newsletters and leaflets issued by Dansungsa, a movie theater in Colonial Korea for a promotional purpose as independent modern media. During the 1920s and 1930s, in tandem with the development of the incipient printing houses in Namchon, Gyeongseong, including Suyeongsa, Dansungsa published promotional prints including weekly newsletters and leaflets in a serial manner to compete with Joseon-gukjang and Umigwan. As these materials contain various information including movie programmes, spectatorship, distributional channels, and promotional strategies that bears witness to theater culture of this time, this paper focuses on the dynamics where not only text and image but also audiences and filmic texts are mediated one another. To this end, the paper has three objectives. First, I argue that weekly newsletters and leaflets can be considered as 'flickering media' that meddles in text and image culture. Second, Dansungsa's promotional prints interpellated film audiences as a loyal fan group while mediating audiences and filmic texts. In doing so, I suggest that these print materials established its own cultural domain differentiated from filmic culture itself. Third, these ephemeral materials contributed to narrowing the gap between colonial Joseon and the World in its imaginary geography through the function of mediation.

The purpose of this study is to analyze the style and the subject of the teaching kits published by the National Archives in the Australia, the USA. and the UK. The teaching kits-the educational document packets-made in printed format or PDF, HTML style are useful tools and better medium with which the national archives support classroom study and publicize the holdings of archives to students and teachers. Although subjects covered in the teaching kits vary slightly according to national circumstances, primary topics are history of nation and government, civil rights, immigration, war, events, culture, and records, etc. It is important to select the theme, find the related original records, and edit packets for students take much interest in.

"책갈피 사이에 피어난 곰팡이가 풍기는 쾨쾨한 냄새, 벽면을 가득 채운 무협지와 순정만화, 책장을 넘기는 소리, 웃음을 참지 못하고 키득거리는 학생들..." $30{\sim}40$대라면 누구나 기억하고 있을 추억 저편 만화방의 모습이다. 일명 '대본소'라고도 불리는 만화방은 $70{\sim}80$년대 마땅한 놀 거리나 휴식 공간이 없는 학생들에게 유일한 휴식처이자 맘껏 상상력을 펼칠 수 있는 '해방구'였다. 젊은 시절이 지나만 기억 속으로 사라지기 쉬운 만화가 최근 들어 연극이나 영화, 드라마로 만들어지는 사례가 늘면서 다시 생활 속으로 들어오고 있다. 한국만화 100돌을 맞는 올해는 정부 차원의 만화 육성방안이 발표되고 국내외 홍보나 기념사업도 풍성하다. 한국 만화가 전 국민의 사랑을 받고 세계 시장에서도 위상을 높여 부활의 꽃을 피우는 새로운 세기를 열지 주목된다.

1980년 설치 이후 환경부는 환경정책과 환경관리에 대한 주요 업무 중의 하나로 자연환경의 보전에 주안점을 두고 있다. 또한 자연환경보전법에 의거하여 환경부는 자연환경상태에 대한 전국 단위의 자연환경조사를 실시하고 있다. 제1차 전국자연환경조사는 이미 1986-1990년에 실시하였고, 현재 교수 및 연구진의 참여 하에 제2차 전국자연환경조사(1997-2002)ff 실시하고 있다. 제2차 조사에서는 지형경관에 대한 조사가 포함되어 모든 종류의 지질 및 지형환경에 대한 조사가 이루어진다. 예를 들면 호수와 습지, 해안, 하천, 산지. 평야, 주빙하지형, 화산, 카르스트 및 구조지형 등이다. 조사지역은 육지 206개 소권역, 해안 145개 지점으로 나누고 6년에 걸쳐 매년 약 30개의 팀이 이 프로젝트에 참여하고 있다. 조사결과는 “지형경관도”로 편집, 인쇄될 예정이며 현존식생도, 동식물분포도와 함께 생태자연도로 작성될 예정이다. 제2차 조사에서 얻어진 방대한 양의 환경정보를 합리적이고 효율적으로 이용하기 위해서 환경부는 한경관리를 위한 이용과 응용에 환경정보시스템을 구축하고 있다.

The anoxic activated sludge process was applied to the treatment of industrial box-mill wastewater, which exhibited the high removal efficiencies of $90{\sim}94%$$ TCOD_{Mn}$ and $58{\sim}81%$ Color. For the design of industrial anoxic activated sludge process, Monod bio-kinetic coefficients of box-mill wastewater were estimated as follows: $K_{max}$(maximum specific substrate removal rate)=0.52 $day^{-1}$, $K_s$(half saturation constant)=314 mg/L, $K_d$(decay coefficient)=0.274 $day^{-1}$, y(microbial yield coefficient)=0.908 mg/mg, and ${\mu}_{max}$(maximum specific growth rate)=0.472 $day^{-1}$. Space loading factors for the design analysis were practically determined as the values of F/M ratio=$0.043{\sim}0.07$ kg-$TCOD_{Mn}$/kg-SS-day, BOD space loading=$0.18{\sim}0.3$ kg-$TCOD_{Mn}/m^3-day$, and ${\theta}_x=6.8{\sim}26.4$ day when considering the relationship of these loading factors with growth dynamics of microorganisms, the F/M ratio that is inversely proportional to ${\theta}_x$ should be equivalent to ${\mu}_{max}$ in units, but exhibited the significant difference between theses two values. Therefore, it is considered that high safety factors are requested in the design of anoxic activated sludge process that is based on Monod bio-kinetics of microorganism.

As the change in the analog age to the digital age with the development of civilization, people are living in a more friendly smart phone screen more books. In the past, people can easily see the text in the book, and now letters are disappearing from people's minds. And although they can see the letters easily anytime, anywhere using smart devices, they have no interest in the letters, they are interested only in information. So, the letters will disappear. However, there are people who try to keep the development of disappearing letters. In this paper, we are planning to produce a documentary about those people. We show that the letters survive in a modern society through Letterpress print shop, calligraphy, a computer font. And it seeks to inform that the letters are valuable.

We propose the various Telemedicine applications using collaborative PACS environment. Traditionally, almost all medical images have been printed on radiological films. These films are expensive to produce and easy to misplace and usually only one copy exists, thus limiting the number of persons who have simultaneous access to the images. But the merit of this system including PACS(Picture Archiving and Communications System ) is very many which are small depository, low maintenance expense, good efficience(storage, speed) and good flexibility but the development costs is higher. This research has been done creating multimedia-based Telemedicine system for home PCs in network environment. Most of Telemedicine used hardware and exclusive line of high cost as CATV broadcasting technique. But this system will contribute to change the Home-PC for better use of collaborations among doctor and patients through various modes of interactions in cyberspace.

A novel method to implement a birdcage-type receiving coil sensor for use in a magnetic resonance imaging(MRI) system has been demonstrated employing a flexible printed circuit board (FPCB) fabrication technique. Unlike the conventional methods, the two-dimensional shape of the coil sensor is first implemented as a FPCB and then it is attached to the surface of a cylindrical supporting structure to implement the three-dimensional birdcage-type coil sensor. The proposed method is very effective to implement object-specific MRI coil sensors especially for small animal measurements in research and preclinical applications since the existing well-developed FPCB-based techniques can easily meet the requirements on accuracies and costs during coil implement process. The performances of the coil sensor verified through $^1H$ 1.5T MRI measurements for small animals and it showed excellent characteristics by providing a high spatial precision and a high signal-to-noise ratio.
