포털 뉴스 유통 전후 일간지 문화면의 지면구조 비교 연구
김진국(Jin-Kuk Kim),하주용(Ju-Yong Ha) 부산울산경남언론학회 2015 지역과 커뮤니케이션 Vol.19 No.4
이 연구는 우리나라 신문이 1995년부터 2010년까지 일간지 문화면의 지면 구성 변화를 알아보기 위하여 조선, 중앙, 경향 등 세 개 일간지의 문화면 기사 모양, 길이, 문체 등에 나타난 특징을 분석하였다. 분석 결과 포털을 통한 뉴스유통이 본격화된 2003년을 전후한 시기 일간지 문화면의 디자인은 기사 모양, 길이, 비주얼 자료의 양 등에서 변화를 보인 것으로 나타났다. 이 기간 지면을 구성하는 요소의 유형이 다양해지고 확장되었는데, 기사모양은 역피라미드형보다는 피라미드형과 변형피라미드형으로 바뀌어 갔다. 기사의 길이도 길어졌으며 사진이나 그래픽 등 비주얼요소의 양도 증가하는 현상이 나타났다. 이 같은 결과는 새로운 미디어 출현에 따른 이용자와 독자의 변화, 미디어의 변화에 따른 신문의 적응과정이라 볼 수 있다. 신문이 과거 6하 원칙에 입각한 역피라미드형 기사와 이를 효과적으로 배치하기 위한 편집전략을 사용해 왔지만, 시대의 변화에 따라 다양한 기사쓰기 방식을 도입하고, 편집 또한 기존 틀을 깬 과감하고 새로운 형식을 시도하는 것으로 평가할 수 있다. Since 2002 portals became major news distributor in Korea. This paper analyzed culture sections of three Korean major daily newspapers, Chosun Ilbo, Joongang Ilbo, and Kyunghyang Shinmun, to find how these newspapers adjusted to the new news distribution environment. This paper conducted a content analysis on culture sections of these three newspaper and compared news structures, lengths of news story, portions of visual items, and writing styles between 1995 to 2002 (Period 1) and 2003 to 2010 (Period 2). After analysing 2,241 news stories in three newspapers, this study find that there have been changes in news structure, length, visual items, and writing style since 2003. More pyramid shape stories than traditional invert-pyramid shape, longer stories, more photos and graphics were found in the culture sections of Period 2 than Period 1. News stories became more soft in writing style, more visualized in structure. The results show that traditional daily newspapers tried to adapt themselves to the new information consumption environment brought by online and social media.

폐타이어의 증가로 인하여 환경문제가 날로 심각해지고 있다. 그러므로 효율적인 재활용을 통하여 이러한 문제를 해결하는데 많은 연구가 진행되고 있다. 본 연구에서는 폐타이어를 상온분쇄기를 제작하여 미세 분말화와 초음파로 처리를 통하여 기본물성을 높이는데 목적을 두었다. 폐고무 분말의 통계학적 분석에 의해서 미세화에 따른 물성의 변화와 물리적 성질을 조사하였고, 기계적 및 가교도 등의 물성을 조사하였다. 또한 광학현미경을 사용하여 표면을 확인함으로서 제품특성을 연구하였다. It goes to be serious with environmental pollution because of great number of waste tires scrapped each year. That is why there are lots of studies for efficient recycle. We tried to reduce particle size of the waste tire powder using a new technology of self-designed grinding machine (SDGM) and ultrasonic treatment. The purpose of this study is to improve the physical properties of reduced waste tire powder. We investigated the fine powder by particle size distribution(PSD) analysis. And also we examined the physical and mechanical properties and cross-link density at various particle size. Also we carried out morphological studies after making the products by SEM.

The paper focuses on an anti-reflection (AR) coating deposited by PECVD in silicon solar cell fabrication. AR coating is effective to reduce the reflection of the light on the silicon wafer surface and then increase substantially the solar cell conversion efficiency. In this work, we carried out experiments to optimize double AR coating layer with silicon nitride and silicon oxide for the silicon solar cells. The p-type mono crystalline silicon wafers with 156*156mm2 area, 0.5-3 Ω·cm resistivity, and 200㎛ thickness were used. All wafers were textured in KOH solution, doped with POCl3 and removed PSG before ARC process. The optimized thickness of each ARC layer was calculated by theoretical equation. For the double layer of AR coating, silicon nitride layer was deposited first using SiH4 and NH3, and then silicon oxide using SiH4 and N2O. As a result, reflectance of SiO2/SiNx layer was lower than single SiNx and then it resulted in increase of short-circuit current and conversion efficiency. It indicates that the double AR coating layer is necessary to obtain the high efficiency solar cell with PECVD already used in commercial line.

N/A It goes to be serious with environmental pollution cause waste rubber. That is why there are lot of studies for efficient recycle. The purpose of this study is to improve the physical properties of EPDM powder by using De-link system. We changed on the size of waste rubber powder and De-link contents. we examined the physical, rheological, mechanical properties. And also examined cross-link state at various De-link. Also we carried out morphological studies after making the weather strip`s feature by optical microscope.

N/A Non-ceramic composite insulator has been interested in the power industry because of its good characteristics in mechanical properties, mass product and design availability. Also it is lighter, and less unexplosive, compared to a ceramic insulator. Especially, EPDM rubber composite insulator can be used for long-term in contaminated environments because of its hydrophobicity. This paper showed the rheological properties, the electrical properties, and contact angles to check the hydrophobicity and the recoverability of the EPDM compounds. Also, we investigated surface morphology of the compound by SEM.
