올해 국내 전기산업의 총 수출액이 사상 최초로 150억 달러를 돌파할 전망이다. 예상대로 되면 2011년 100억 달러를 돌파한지 4년 만에 50% 급상승이라는 신기원을 기록하게 된다. 수출과 달리 내수는 상당히 힘든 한 해를 보낼 것으로 보인다. 한전의 수요 증가 등 긍정적 측면도 있지만, 조선 철강 등 관련 산업의 부진이 악영향을 미칠 가능성이 더 크다는 분석이다. 한국전기산업진흥회는 최근 이 같은 내용을 담은 '2015년 전기산업 동향 및 전망' 보고서를 발표했다. 주요 내용을 정리해봤다.

ACF, which is used for the transparent electrode film is manufactured by the thermocompression method with conductive particles. However, the method has disadvantages since there are many wasted materials and the process is complex. To overcome the demerits of the conventional method, EHD printing technology with conductive particles ink is proposed. The line thickness of patterning is influenced by the characteristics of the inks and the printing conditions. Therefore, it is salient to find the most conducive conditions for the micro patterning. In this paper, the ink with conductive particles was manufactured, and the patterning results were obtained by varying the nozzle thickness and the flow rate. The electrical conductivity according to the ejection of the particles ink is obtained.

우리는 조선시대에 제작된 소규표의 크기와 설치 위치에 관한 연구를 수행하였다. <세종실록>의 기록에 의하면 40척의 규표(이하 대규표)는 1432년(세종 14)과 1437년(세종 19) 사이에 제작되어 간의대 서쪽 옆에 세웠다는 사실은 잘 알려져 있다. 반면 소규표에 대해서는 그동안 잘 알려진 바가 없었다. 그러나 이순지의 <제가역상집>과 기타 여러 문헌 연구를 통해 소규표도 조선전기에 제작되었음을 알 수 있다. 또한 <명종실록>에는 동지와 보름에 대규표와 소규표를 이용하여 해와 달의 그림자길이를 관측한 기록이 있다. 이 연구에는 이러한 소규표 관련 문헌들의 내용을 소개하고자 한다. 아울러 <명종실록>의 기록과 현대 천체역학적 계산을 통해 소규표의 표의 길이는 전통적인 규표의 크기인 8척임을 알 수 있었다. 한편 소규표는 경복궁 간의대 주변에 설치되었던 것으로 보인다. 이러한 연구 결과들은 향후 규표 복원 연구에 매우 유용하게 활용될 것으로 기대된다.

We have investigated and conserved three small Buddha statues dating from Joseon period that were purchased by the National Museum of Korea. Chemical analysis and investigation of internal structures were enabled us to identify its compositions and hollow spaces which have various materials just like fabrics, silver ornaments, beads and wood fragments. The fabrics date from the early years of the Joseon dynasty to the middle one. The compositions of matrix of the Buddha statues vary 80-90 wt% Ag and 7-15 wt% Cu. And its surface layers were gilt with amalgam. Mechanical and chemical cleaning with EDTA-2Na were applied together during the cleaning process.

The purpose of this study is to find the theories of public policy in Confucian politics during Choson Dynasty. As a result of the analysis, there are five implications. First, the area of Confucian policy of Choson consisted in authority, organization, financial policy, affection for the people, and li(ritual propriety). Second, major political context had been maintained from King Se-Jong, through King Sung-Jong and King Yeong-Jo to King Jeong-Jo in the perspective of dynasties' characteristic. Third, there were major ideas on Confucius's idea for li in early period, $Zh{\bar{u}}z{\check{i}}^{\prime}s$ idea for the authority in late period and Mencius's idea for financial policy in major risk situation. Fourth, there were five periods with establishment, foundation, crisis, restoration and collapse in the change of public policy. Fifth, $Zh{\bar{u}}z{\check{i}}^{\prime}$ and $Ch{\acute{e}}ng{\cdot}zi$ had influenced bigger than Confucius as a factors of policy making. This study has been promoted the complement of context analysis and understanding of semantic analysis with implementing dictionary using two language with Korean and Chinese.

This study is carried out to investigate the pubishing culture in Chonnam province during the latter half of Chosun Dynasty. The subjects, dates, and places of publication are analyzed from the books which have been found in the publication records and the catalog of woodblocks. Right after the war, Samryakjikhae and Sohakjipsul were published at Jukchunseodang, Bosung area. Anthologies were published dominantly through the whole period. Naju was the center of publication in 17 & the first half term 18 centuries and then moved to Jangwheung area. In this period, publication of genealogical records, biographies, anthologies, geography books had been increasing vastly. From the 19 century, most books were published by using the wooden type. The wooden type was used because the contents of books were for the limited number of publication. The most active publication happened at the end of 19th century. Significance of Confucian literature, collective anthologies, medical science, and confucious classics decreased in the latter half.

This study excludes how to define the concepts and categories of the Ah-ak(雅樂) and Sok-ak(俗樂). In the process from the early Joseon Dynasty to the late Joseon Dynasty, the aesthetic appreciation system of the Ah-Sok(雅俗) in traditional music, which is consistently projected on court music and folk music centered on Pungryubang, was revealed through specific historical records. Through this study, we were able to examine as follow : In the early Joseon Dynasty, the aesthetic of music related to the the Ah-Sok(雅俗) was mainly projected on the court's ritual music and Yeonhyangak-music for korean court banquet-, and in particular, the aesthetic thoughts of Geomungo[玄琴] was at the center. As we descend to the late Joseon Dynasty, the aesthetic of music related to the Ah-Sok(雅俗) has been expanded to the private sector, reflecting the aesthetic of Pungryubang music, and it can be seen that the aesthetic thought of Geomungo[玄琴] was at the center.
