Abstract

해당 연구는 극장용 애니메이션을 서사를 중심으로 갈등을 분석하기 위해 영상에서 갈등을 분류하는 객관적이고 타당한 방법이 필요함을 인식하면서 시작되었다. 아울러 갈등을 효과적으로 비주얼 스토리텔링 하는 요소로 주인공의 정서에 주목하고, 갈등에서 나타나는 주인공의 정서를 연구하려 한다. 연구의 목적은 갈등강도와 갈등에 나타나는 정서를 분석하는 것이다. 연구결과 및 내용은 다음과 같다. 첫째, 서사의 이론적 고찰을 통해 극적전환점을 찾아 내고, 갈등 분류 모델(Conflict 6B Model)을 제안하였다. 둘째, 갈등 분류 모델을 이용하여 이론에 기반한 갈등 샷(shot) DB를 추출하였다. 셋째, 내적, 초개인적 갈등에서 강도와 정서를 찾아내었다. 넷째, 내적, 초개인적 갈등에서 강도와 정서의 전문가 실험 및 검증을 실시하였다. 본 연구는 애니메이션에서 갈등에 대한 주인공 정서의 서사적, 시각적, 심리학적인 다학제적 연구로 추출된 메타데이터(Metadata)는 애니메이션 서사에서 갈등의 비데오 인덱싱(Video Indexing)에 적용 될 것으로 기대한다.

Abstract

The perovskite direct current nanogenerator (PDCG) is a novel energy conversion device with remarkable performance and comprehensive prospects. However, the interface of the perovskite Schottky junction still requires further optimization. Herein, an innovative approach by engineering a two-dimensional/three-dimensional (2D/3D) layered structure through phenylethylammonium iodide (PEAI) modification was introduced This novel modification significantly enhances the triboelectric effects in the Cs0.05(FA0.85MA0.15)0.95Pb(I0.85Br0.15)3/aluminum (CsFAMA/Al) Schottky junction PDCG, featuring a rolling structure. The PEAI-modified PDCG demonstrates a substantial improvement in performance, achieving an open circuit voltage (Voc) of 0.69 V, and a short circuit current (Isc) of 1.51 mA. Under 3 W illumination, the current density (Jsc) of PDCG with PEAI could achieve 92.81 A/m2, representing a 1.98-fold enhancement, realizing synergistic energy harvesting from mechanical and light energy. Furthermore, the innovative 2D/3D layer design significantly boosts the PDCG’s operational stability, reducing performance degradation. Notably, after a 9 h aging at 100°C, the Iscof the PDCG modified with PEAI maintained 85 % of its original value, a substantial improvement compared to the 68 % retention observed in the unmodified PDCG. The development of PDCG converting mechanical energy directly into direct current (DC) while possessing characteristics of integration and miniaturization, holds significant practical significance.
