비정질 루테늄 산화물을 사용한 수퍼캐패시터를 개발하였다. 삼염화루테늄 수화물$(RuCl_3{\cdot}xH_2O)$로부터 제조한 비정질의 이산화루테늄 수화물$(RuO_2{\cdot}nH_2O)$을 사용하여 수퍼캐패시터 전극을 제조하였다. 집전체로는 티타늄 및 STS 304박막에 비해 보다 넓은 전위창을 가지는 탄탈륨 박막을 사용하였다. 제조한 전극과 4.8M 황산 전해액을 사용하여 수퍼캐패시터를 제조하였다. 전극의 비정전용량은 순환전위전류분석에서 미분 최대 값으로 산화 및 환원 과정 각각 710 및 $645\;F/g-RuO_2{\cdot}nH_2O$이었으며, 평균값은 $521\;F/g-RuO_2{\cdot}nH_2O$으로 나타났다. 수퍼캐패시터를 포화카로멜기준전극에 대하여 0.5 V로 protonation level을 조정하고, 충방전 시험한 바, $151\;F/g-RuO_2{\cdot}nH_2O$의 비정전용량을 나타내었다. A supercapacitor was developed using an amorphous ruthenium oxide material. The electrode of supercapacitor was prepared using an amorphous ruthenium oxide, which was synthesized from ruthenium trichloide hydrate$(RuCl_3{\cdo5}xH_2O)$. Thin film of tantalum was used as a current collector because it had wide. potential window characteristics than titanium and 575304 materials. A supercapacitor was assembled with ruthenium oxide as an electrode active material and 4.8M sulfuric acid solution as an electrolyte. The specific capacitance of the electrode was tested by a cyclic voltammetry using a half cell. The maximum differential specific capacitances during the oxidative and the reductive scans were 710 and $645\;F/g-RuO_2{\cdot}nH_2O$, respectively. The average specific capacitance was $521\;F/g-RuO_2{\cdot}nH_2O$. The assembled supercapacitor was protonated to the potential level of 0.5V vs. SCE. Super-capacitor, which was adjusted to the appropriate protonation level, had the specific capacitance of $151\;F/g-RuO_2{\cdot}nH_2O$ based on the concept of full cell.

최상진,반재경,Choi, Sang-Jin,Pan, Jae-Kyung 대한전자공학회 2013 전자공학회논문지 Vol.49 No.11

본 논문에서는 자기기준 특성을 가지는 광세기 기반 광섬유 센서 구조를 제안하고 실험적으로 구현하여 성능을 제시한다. 제안하는 광섬유 센서는 광대역 광원(BLS), fiber Bragg grating (FBG), 가변 페브리-페로(Fabry-Perot) 필터, LabVIEW 프로그램으로 구성된다. 제안한 자기기준 광섬유 센서의 이론적인 해석을 통하여 측정 변수(X)와 보정 변수(${\beta}$)를 정의하고, 이를 바탕으로 전달함수(H)를 구한다. 또한 실험을 통하여 이론적인 해석의 타당성을 제시한다. 제안한 광섬유 센서 구조는 광대역 광원의 출력 광세기가 0 dB, 3 dB, 6 dB 감소해도 측정결과에 영향을 미치지 않는 자기기준 특성을 가진다. 또한 다른 특성의 FBG를 사용하여도 측정 가능하므로, 제안한 광섬유 센서 구조는 임의의 규격을 가진 FBG를 사용할 수 있다. 광원의 광세기가 감소하였을 때와 세 가지 다른 특성의 FBG 쌍을 이용하여 측정한 결과 이론적인 값과 잘 일치함을 보였다. 따라서 제안한 광섬유 센서는 자기기준 특성과 구성하는 FBG의 규격이 비교적 엄격하지 않아도 되는 장점을 가진다. In this paper, we have proposed and experimentally demonstrated an intensity-based self-referencing fiber optic sensor. The proposed fiber optic sensor consists of a broadband light source (BLS), fiber Bragg grating (FBG), tunable Fabry-Perot (F-P) filter, and LabVIEW program. We define the measurement parameter (X) and the calibration parameter (${\beta}$) to determine the transfer function(H) of the self-referencing fiber optic sensor, and the validity of the theoretical analysis is confirmed by experiments. The self-referencing characteristic for the proposed system has been validated by showing that the measurement parameter (X) is invariant for BLS optical power attenuations of 0 dB, 3 dB, and 6 dB. Also, the measured result is irrelevant to the FBGs with different characteristics. This means that the proposed fiber optic sensor offers the flexibility for determining the FBGs needed for implementation. Experimental results for the proposed fiber optic sensor are in good agreement with a theoretical analysis for BLS optical power attenuations and for three FBG pairs with different characteristics. So, the proposed fiber optic sensor has several benefits, including the self-referencing characteristic and the flexibility to determine the FBGs.

실체명사(實體名詞)의 의미형질(意味形質) 분석(分析)

최상진 ( Choi Sang-jin ) 한국어문교육연구회 2008 어문연구(語文硏究) Vol.36 No.2

이 論文은 實體名詞를 對象으로 單語가 文章의 意味構成要素로서 구실을 할 때, 그 意味成分은 어떻게 分析되어야 할 것인가를 考察한 것이다. 이 연구는 用法說을 바탕으로 實體名詞가 意味形質이라는 資質模型으로 분석될 수 있음을 提案하여 單語意味 成分分析에 대한 새로운 方法을 摸索해 보았다. 實體名詞의 의미형질을 形相과 質料라는 두 資質因子로 분석하였다. 實體名詞의 단어의미는 홀로 獨立해 있을 때는 하나의 個別 意味單位지만 文章 속에서는 意味構成要素이다. 독립된 의미단위로서의 단어는 여럿의 義素를 未分化的으로 가지고 있는 意味이며, 문장 의미구성요소로서의 단어는 固定된 하나의 義素를 가진다. 이 意味構成要素는 문장 속에서 部分과 部分, 部分과 全體의 有機體的 共起關係를 통한 自己組織으로 의미를 얻는다. 실체명사의 意味領域은 流動的이며 다른 의미구성요소와의 意味的 共起關係로 의미가 轉移될 수 있다. This study aims at laying an methodological foundation upon the provision of more specified semantic components of the substance noun of Korean by analyzing its semantic form and matter. Just as every existing substance of the world has its own features, the meaning of the word signifying its existence also has its own semantic features. The semantic features of the word are products of concepts created in the space of human spirit, and they have abstract semantic quality and quantity. First, the semantic form and matter refers to the unique semantic quality and quantity of a word, which is divided into two semantic atomics, form and matter. Form and mater refer to reference and sense, respectively. Secondly, the semantic domain of the substance noun can be spread in a sentence, and this, in turn, changes its semantic form and matter. Thirdly, the substance noun acts as a semantic constituent of a sentence, forming a partial meaning space in a whole meaning space of a sentence. It gains its own semantic form and matter through the self-organization among partial meaning spaces. Fourthly, the semantic form and matter of a word in isolation is different in semantic quality and quantity from that of a word acting as a semantic constituent of the sentence. A substance noun in isolation is the undivided whole of many sememes, and it gains a single sememe when it is related to other semantic constituents in a specific sentence. Fifthly, semantic form and matter can be divided into form semantic feature and matter semantic feature. The form semantic feature of a substance noun can be subdivided into unit, boundary, division, and continuity. The matter feature of a concrete noun can be dealt with the hierarchy of a semantic domain.
