  • The PZT thin films werre deposited on Pt/Ti/$SiO_2$/Si substrate by R. F. magnetron sputtering with $Pb_{1.1}Zr_{0.53}Ti_{0.47}O_3$ target. When interlayers(PbO, $TiO_2$, PbO/$TiO_2$) were inserted between PZT and Pt, the crystallization of the PZT thin films was considerably improved and the processing temperature was lowered. Compared to the pure PZT thin films, dielectric constant, dielectric loss and polarization properties of PZT thin films with interlayers were considerably improved. From XPS depth profile analysis, it was confirmed that PZT thin films and interlayers existed independently. In particular, PZT thin films deposited on interlayer(PbO/$TiO_2$) showed the best dielectric property (${\varepsilon}_r$=414.94, tan${\delta}$=0.0241, Pr=22${\mu}C/cm^2$).

  • This study is to analyze whether the use of SNS in politics has any political effects. Most previous studies on political participation by SNS tended to just focus on the participation difference between SNS users and non-users. The test results first show that the development of ICT increases citizens' interest in political information and differentiate the methods of their political participation. Second, we identified SNS users tend to have higher reliability in political information and greater transversion effects by the use of media. Finally, the study verifies SNS is a more effective tool in collective actions such as non-customary rallies and demonstration rather than in customary political participation.

  • In the US, there are no governing bodies within the federal executive departments dedicated to the arts and cultural affairs. Direct government subsidies for the arts are relatively small compared to other countries with a comparable economy and standard of living. Nevertheless, the US produces artworks, artists, and arts groups, leading the world's arts and culture. Incorporating the concepts of network governance and shared governance, this paper examines the dynamic roles and interrelationships among various for-profit/nonprofit arts organizations, foundations, councils, service organizations, arts advocacy groups, and professional/amateur associations from the federal to local levels that compose the ecology of American arts and culture. Through our evaluation, we conclude that the local/state/federal arts agencies and arts organizations at various levels influence each other via the principle of subsidiarity and isomorphism, creating a unique cultural policy and arts-supporting system that correspond to the political and social structure and environment of the United States.

  • Stable operation of semiconductor devices is needed even at high temperatures. Among the structures of semiconductor devices, the area that can cause unstable electrical responses at high temperatures is the contact layer between the metal and the semiconductor. In this study, the effect of annealing conditions included in the process of forming a contact layer of nickel silicide(NiSix) on a p-type SiC layer on the specific contact resistance of the contact layer and the total resistance between the metal and the semiconductor was investigated. To this end, a series of electrodes for TLM (transfer length method) measurements were patterned on the 4 inch p-type SiC layer under conditions of changing annealing temperature of 1700 and 1800 ℃ and annealing time of 30 and 60 minutes. As a result, it was confirmed that the annealing conditions affect the resistance of the contact layer and the electrical stability of the device.

  • The purpose of this study is to analyze trilogy by means of semiotics. trilogy constructs a story as a whole while each piece delivers a concluded ending. This study used 'modele actantiel' and 'carre semiotique' of Greimas in order to clarify not only the meaning structure but also the course of narrative of . is a compelling story which reverses the fairy tale of a beautiful princess and a heroic prince. Each piece of the trilogy unfolds as following; (1)ls the love of a princess and an ogre possible? (2)Can the marriage of the couple get confirmed? (3)Can Shrek be free again? The repeated meaning structure of trilogy is the binary opposition of nature versus culture, and the narrative course forms the meaning square on the basis of the opposition. Human culture represented by the lord Farquaad and Duloc castle signifies cleanness, order, complex, anxiety, paranoia, authoritarian, and violent. On the contrary, Nature represented by Shrek and the swamp signifies barbarity, freedom, confident, maturity, unstrained, and humar. The meaning of Shrek series is generated by the structure of the basic discrimination of culture versus nature. However, as story twists the bias and fixed idea, the meaning structure of Shrek shows a unique relationship of culture and nature. Although Shrek, an ogre, lives alone in a swamp because of the bias of human world, he is depicted as self-sufficient, comfort, and broad-minded. On the basis of this meaning structure, Shrek is not a story that an ogre(nature) strives to enter the human culture, nor a story that nature wins a victory at the confrontation between culture and nature, but a story that human(culture) and ogre(nature) overcome their fixed ideas through the transition from culture to nature and vice versa.

  • 본 논문의 목적은 게르만제어(예를들어 고트어, 고대북구어, 고고지독일어, 고대영어 등)에 나타나는 공명음중복 현상이 원-인도유럽어시기의 후두음에 기인함을 보이는 것이다. 고트어의 ddj/ggw, 고대북구어의 ggi/ggr, 고고지독일어 ij/uw (이상 소위 '예음화현상'으로 불림)와 그 외 게르만제어에 공통적으로 나타나는 공명음들의 중복, -rr-, -ll-, -nn-, -mm- 등은 원-게르만어시기에 각각 $\ast-ii-,\;\ast-uu-,\;\ast-rr-,\;\ast-ll-,\;\ast-nn-,\;\ast-mm-$ 등으로 소급된다. 그러나 이러한 자음군이 게르만어 이외의 다른 인도유럽어들( 대표적으로 고대인도이란어, 고전희랍어, 라전어 등)과 비교되어 원-인도유럽어시기로 소급되는 경우, 각각 $\ast-iH-,\;\ast-uH-,\;\ast-rH-,\;\ast-lH-,\;\ast-nH-,\;\ast-mH-$ 등으로 재구된다. 따라서 원-게르만어의 자음중복 현상이 후두음의 영향으로 나타난 것으로 해석되는데, 아마도 후두음이 선행하는 공명음에 동화되어 일어난 것으로 보인다. 소쉬르(1987)이래 발전해 온 후두음이론은 현재 그 이론적 틀을 확립한 상태이다. 이 이론은 고전 인도유럽어학에서 설명하지 못했던 여러 언어현상들을 설명하였고, 현대 인도유럽어 역사비교언어학에서 언어변화에 대한 필수적인 설명기재로서 사용되고 있다. 원-인도유럽어의 많은 특징들을 계승한 전형적인 다른 고대 인도유럽어들과는 달리, 시기적으로 늦은 고대 게르만어에서 음운론적 층위에서 공명음중복 현상이 후두음에 기인함은 인도유럽어 역사비교언어학에서 뿐만 아니라 게르만어학에서도 큰 의미를 갖는다고 볼 수 있다.간접으로 본동사 앞에 놓여 있어야 되는 모든 문장성분과 부문장 때문에, 즉 한국어의 전면적인 전위수식 현상으로 흔히 큰 부담/복잡함을 야기한다는 데에 그 원인이 있다. 이러한 상황에서 동사는 가능한 한 그의 문장성분을 줄이려 한다. 통사적으로 보장되어 이미 있으니 말이다. 그래서 한국어 동사의 부정성은 일종의 부담해소 대책으로 간주될 수 있을 것이다. $\ast$ 두 비교 대상에서의 핵 및 최소문장 가능성은 역시 원자가에 대한 비구속성에서 비롯된다. $\ast$ 우리 한국인이 빨리 말할 때 흔히 범하는 부정성으로 인한 인칭변화에서의 오류는 무엇보다도 정형성/제한성을 지닌 독일어 정동사가 인칭 변화하는 데 반해 한국어에서는 부정성/비구속성을 지닌 동사가 그것과는 무관한 페 기인한다. 동사의 속성을 철저히 분석함으로써 이런 과오를 극복해야 할 것이다. 한국어 동사의 부정성은 지금까지 거의 연구되지 않았다. 이 문제는 또한 지속적으로 수많은 다른 자연어들과의 비교분석을 통해 관찰돼야 할 것이다. 이 논문이 이런 연구와 언어습득을 위한 작업에 도움이 되기를 바란다.적 성분구조가 다르다는 것을 알 수 있다. 우리는 이 글이 외국어로서의 독일어를 배우는 이들에게 독일어의 관용구를 보다 올바르게 이해할 수 있는 방법론적인 토대를 제공함은 물론, (관용어) 사전에서 외국인 학습자를 고려하여 관용구를 알기 쉽게 기술하는 데 도움을 줄 수 있기를 바란다.되기 시작하면서 남황해 분지는 구조역전의 현상이 일어났으며, 동시에 발해 분지는 인리형 분지로 발달하게 되었다. 따라서, 올리고세 동안 발해 분지에서는 퇴적작용이, 남황해 분지에서는 심한 구조역전에 의한 분지변형이 동시에 일어났다 올리고세 이후 현재까지, 남황해

  • This study was carried out to provide a basic data for preservation of Pinus desiflora forest as cultural landscape forest by analyzing characteristics of plant community of P. desiflora forest in Geumjeongsan(mountatin) in Busan city. In order to analyze plant community of P. densiflora in Geumjeongsan, we set up 10 study plots inside and 8 plots outside of Geumjeongsansung(mountain fortress, hereinafter 'Sansung')(unit area: $400m^2$), a total of 18 plots. TWINSPAN analysis divided these 18 study plots into 6 communities which are Querqus serrata-P. desiflora community, P. desiflora community, P. desiflora-Q. serrata community, P. thunbergii-P. densiflora community, P. densiflora-P. thubergii-Q. acutissima community, and P. densiflora-Platycarya strobilacea community. Importance Percentage (I.P.) of each area and DBH class distribution of main species showed that P. densiflora community would succeed to Q. serrata community or C. tschonoskii community. Analysis on tree age found out that communities in the Sansung were 32~37 years old and those outside the Sansung were 44~57 years old. Shannon's species diversity index ranged from 0.4826 to 1.2499. Regarding correlation between species, P. densiflora had negative correlation with Styrax japonica. Based on abovementioned result we expected ecological succession from P. densiflora community to Q. serrata community inside of the Sansung. Outside the Sansung, succession from P. densiflora-P. thunbergii community to C. tschonoskii-Q. serrata community was expected. In order to manage P. densiflora forest as cultural landscape forest, Q. spp in the understory and shrub layer and deciduous broad-leaved arboreal trees should be managed. Tree crown management of deciduous broad-leaved trees in competition with P. desiflora, is also required.
