남북한 사회문화 통합에 관한 연구 - 윤리문화적 접근 모델을 중심으로 -

조현봉 ( Cho¸ Hyun-bong ) 한국윤리학회 2021 倫理硏究 Vol.134 No.1

본 연구는 오늘날 우리사회에서 남북 통일 및 통합의 새로운 접근방법으로 제기되고 있는 사회문화 통합의 근본적이고 실천적 규범체계를 세우는 것이다. 남북한 사회문화 통합에 있어서 윤리적 당위와 문화적 가치의 균형적 조화와 올바른 실천의 사고와 행동, 요구되는 덕목과 역량의 설정의 윤리문화적 사유와 가치체계를 적용하여 사회문화 통합의 적실성과 타당성을 확보함으로써 완전한 통일과 올바른 통합을 견인하는 진정한 통합력을 이끌어 내는 남북한 사회문화 통합의 접근 논리와 방법을 제시하는 것이다. 이를 통해 사회적으로 통일에 대한 당위성과 필연성을 제고시키고 학문적으로 사회문화 통합과 관련한 인문학적 담론과 연구를 촉진시켜 통일 및 통합의 이론체계를 발전시키며 철학적 토대를 보강할 수 있는 대안을 제안하고 있다. This study is a research methodology for social and cultural integration that promotes complete unification and desirable integration by applying an ethical and cultural approach to the integration between North and South Korea. The main contents are establishing the concept of social and cultural integration, exploring the approach logic, an ethical and cultural approach model and direction of application, and a suggestion of an ethical approaches to social and cultural integration between the two Koreas. The findings are expected to contribute to strengthening the theoretical framework and philosophical foundation related to the unification and integration of the two Koreas.

Choi, Hyunbong,Cho, Nara,Paek, Sanghyun,Ko, Jaejung American Chemical Society 2014 The Journal of Physical Chemistry Part C Vol.118 No.30

<P>We meticulously designed organic antenna for the ruthenium phthalocyanine. A significant enhance-ment of photocurrent in JK-107 is attributed to a Förster energy transfer and intramolecular electron transfer from the antenna to the acceptor RuPc3. We demonstrate the direct evidence of Förster energy transfer and electron transfer for the enhanced photocurrent generation using photoluminescence spectroscopy and transient absorption spectroscopy, respectively.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2014/jpccck.2014.118.issue-30/jp407475b/production/images/medium/jp-2013-07475b_0011.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp407475b'>ACS Electronic Supporting Info</A></P>

<B>Graphic Abstract</B> <P>Dying to get inside: Charge recombination is retarded and dye aggregation is prevented in solar cells that contain the JK-2 dye encapsulated in a cyclodextrin (CD) cavity (see picture). The β-CD/JK-2 device with a polymer gel electrolyte gave an overall conversion efficiency of 7.40 %, which is the highest value reported to date for DSSCs based on the organic sensitizers, and showed excellent stability. <img src='wiley_img/14337851-2009-48-32-ANIE200902013-content.gif' alt='wiley_img/14337851-2009-48-32-ANIE200902013-content'> </P>

<P>We have designed and synthesized highly efficient organic sensitizers with a planar thienothiophene–vinylene–thienothiophene linker. Under standard global AM 1.5 solar conditions, the JK-113-sensitized cell gave a short circuit photocurrent density (J<SUB>sc</SUB>) of 17.61 mA cm<SUP>−2</SUP>, an open-circuit voltage (V<SUB>oc</SUB>) of 0.71 V, and a fill factor (FF) of 72 %, corresponding to an overall conversion efficiency (η) of 9.1 %. The incident monochromatic photo-to-current conversion efficiency (IPCE) of JK-113 exceeds 80 % over the spectral region from 400 to 640 nm, reaching its maximum of 93 % at 475 nm. The band tails off toward 770 nm, contributing to the broad spectral light harvesting. Solar-cell devices based on the sensitizer JK-113 in conjunction with a volatile electrolyte and a solvent-free ionic liquid electrolyte gave high conversion efficiencies of 9.1 % and 7.9 %, respectively. The JK-113-based solar cell fabricated using a solvent-free ionic liquid electrolyte showed excellent stability under light soaking at 60 °C for 1000 h.</P> <B>Graphic Abstract</B> <P>On the rise!

Supersensitization of CdS Quantum Dots with a Near-Infrared Organic Dye: Toward the Design of Panchromatic Hybrid-Sensitized Solar Cells

Choi, Hyunbong,Nicolaescu, Roxana,Paek, Sanghyun,Ko, Jaejung,Kamat, Prashant V. American Chemical Society 2011 ACS NANO Vol.5 No.11

<P>The photoresponse of quantum dot solar cells (QDSCs) has been successfully extended to the near-IR (NIR) region by sensitizing nanostructured TiO<SUB>2</SUB>–CdS films with a squaraine dye (JK-216). CdS nanoparticles anchored on mesoscopic TiO<SUB>2</SUB> films obtained by successive ionic layer adsorption and reaction (SILAR) exhibit limited absorption below 500 nm with a net power conversion efficiency of ∼1% when employed as a photoanode in QDSC. By depositing a thin barrier layer of Al<SUB>2</SUB>O<SUB>3</SUB>, the TiO<SUB>2</SUB>–CdS films were further modified with a NIR absorbing squaraine dye. Quantum dot sensitized solar cells supersensitized with a squariand dye (JK-216) showed good stability during illumination with standard global AM 1.5 solar conditions, delivering a maximum overall power conversion efficiency (η) of 3.14%. Transient absorption and pulse radiolysis measurements provide further insight into the excited state interactions of squaraine dye with SiO<SUB>2</SUB>, TiO<SUB>2</SUB>, and TiO<SUB>2</SUB>/CdS/Al<SUB>2</SUB>O<SUB>3</SUB> films and interfacial electron transfer processes. The synergy of combining semiconductor quantum dots and NIR absorbing dye provides new opportunities to harvest photons from different regions of the solar spectrum.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2011/ancac3.2011.5.issue-11/nn2035022/production/images/medium/nn-2011-035022_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn2035022'>ACS Electronic Supporting Info</A></P>
