본 연구는 SNS의 여론형성과정과 참여행태에 관한 연구이다. 대표적인 SNS 서비스인 트위터가 무상급식 주민투표와 10.26재보선 기간의 여론형성에 미치는 영향을 고찰하였다. 특히, 여론형성의 유력자인 파워 트위터리안이 영향력을 분석하였다. 첫 번째 연구문제인 트위터의 여론형성에 관한 분석결과, 무상급식 주민투표의 경우 오전시장이 대권 불출마선언 이후에 무상급식 주민투표에 대한 국민들의 관심이 폭발적으로 늘어났으며, 오전시장을 지지하는 트윗보다는 반대하는 트윗의 영향력이 컸다. 10.26재보선의 경우 트위터공간에서 나 후보자보다는 박 후보자가 촘촘한 소통망을 형성하면서 자신에게 호의적인 여론을 형성하였다. 두 번째 연구문제인 파워 트위터리안과 일반 트위터리안의 참여행태에 관한 분석결과, 무상급식 주민투표의 경우 유명스타들이 파워 트위터리안으로써 사회이슈에 대한 참여를 선도하는 역할자로 자리매김하게 되는 계기를 마련했다. 파워 트위터리안은 일반 트위터리안의 공감을 끌어내는 데 성공하였다고 평가된다. 10.26재보선의 경우 박 후보를 지지하는 파워 트위터리안이 나 후보를 지지하는 파워 트위터리안보다 많았을 뿐만 아니라 박 후보와 소통을 하고 있는 일반 트위터리안도 훨씬 많았다. 특히, 박 후보를 지지한 파워 트위터리안이 보유한 커뮤니티의 규모는 나 후보를 지지한 파워 트위터리안의 5배가 넘었다. 파워 트위터리안과 일반 트위터리안의 관계는 단순한 지지가 아닌 서로 간의 공감을 전제로 관계가 형성되고 있다. 전통적인 언론을 통한 여론형성과정에서 국민들은 단순히 여론에 휩쓸리는 대상에 불과하였지만, SNS가 확대되면서 이슈의 생산과 유통에 참여하고 이슈를 선도하는 역할을 하는 것으로 평가된다. This study is critical research on the forming public opinion of SNS and participation behavior. Twitter is a typical SNS service, free school food and 10.26 re-and by-elections during the formation of public opinion on the impact have been investigated. Formation of public opinion about Twitter’s analysis of the first research question, The case of free meals to support the Mayor Oh, rather than against Twitter were influential. 10.26 re-and by-elections Twitter in space, the Park‘ candidate than Na’ candidate has formed a favorable opinion. Power twitterian and twitterian on the behavior of the second study involved analysis of the problem, For free meals, power twitterian were responsible for leading the public opinion. For 10.26 re-and by-elections, Power twitterian were more Park‘ candidates than Na’ candidates. In addition, Park‘ candidates of twitterians were communicating more. Through traditional media in the process of forming public opinion was swayed by public opinion to the target people simply but SNS age people involved in the production and distribution of the issue and the issue has a leading role.

Collaborative product commerce (CPC) supports a collaboration that a global enterprise and customer related to lift cycle of product share product information and a collaboration process for the collaboration, and integrating applications. In this paper, we use common data schema in order to solve a interoperability problem about shared product information between enterprises. And we map to common data schema from each other different data format. Therefore we implement CPC Adaptor in order to integrate distributed product information.

The surface reactions of silica film($SiO_2-P_2O_5-B_2O_3-GeO_2$) with fluorocarbon plasma has been studied by using angle -resolved x-ray photoelectron spectroscopy(XPS). It has been confirmed that residual carbon consists of C-C and C-CFx bonds and fluorine mainly binds silicon in the case of etched silica by using $CF_4$ gas plasma. The surface reaction of silica with various fluorocarbon gases, such as $CF_4,C_2F_6 and CHF_3$ were investigated. XPS results showed that though the etching gases were changed, the elements and binding states of the residual layers on the etched silica by using various fluorocarbon gas plasma were nearly the same . This seems to be due to the high volatility of byproducts, that is, $SiF_4 and CO_2$ etc..

The superconducting synchronous generator is one of the breakthrough elements for direct-drive wind turbines because it is light and small. Normally the superconducting one has copper armature windings in the stator and superconducting field windings on the rotor. The high resistance of the armature can make large copper losses, comparing with the conventional generators with a gear box. One of the solutions for the large copper losses could be a fully superconducting generator. But the high magnetic fields from the superconducting field windings on the rotor also make high perpendicular magnetic fields on the superconducting tapes in the armature windings. We have proposed a fully superconducting synchronous generator with dual field windings. It could immensely decrease the circumferential component of the magnetic field from the field windings at the armature windings. In this paper, we conceptually designed 3 types of superconducting synchronous generators. The first one is the fully superconducting one with conventional structure, which has superconducting armature windings in the stator and superconducting field windings on the rotor. The second one is the one with dual superconducting field windings and superconducting armature windings between them. The last one is the same as the third one except the structure of the armature. If the concentrated armature windings are superconducting ones with cryostats, then they cannot be installed within the span of 2 poles. So, we adopted 3 phases windings within 4 poles system. It makes more AC losses but can be manufactured really.
