研究室紹介
Professor Donghyun Lee's research lab focuses on advanced materials and sustainable technologies, with key research directions in organic electronics, particularly single-layer OLEDs fabricated via scalable methods like screen printing; bioinspired and biodegradable materials for biomedical applications such as nerve guidance conduits; and the integration of design theory with functional performance in graphic design and human factors. The lab also explores performance optimization in sports science through personality, temperament, and self-efficacy analysis in elite athletes, as well as energy-efficient building simulation using Bayesian calibration techniques.

Selected Papers
15Single-layer organic-light-emitting devices (OLEDs) have been fabricated by screen printing method. Using the screen printing method, a polystyrene (PS) film doped with NPB, Alq3, and rubrene was deposited to have the thickness of 100 nm. The film was used for the fabrication of single-layer OLEDs. In order to estimate the performance of the devices, single-layer OLEDs of the same structure were also fabricated by spin coating and compared with those fabricated by screen printing. The spin-coate
본 연구는 엘리트 운동선수들의 운동유형에 따른 사상체질과 성격유형 및 신체자신감의 관계를 규명하는데 있었다. 수도권 지역의 각 종목 운동선수를 대상으로 설문조사를 실시하였으며, 총 476명을 연구 자료로 채택하였다. 자료의 분석은 빈도분석과 요인분석 및 신뢰도 검사, 교차분석, 분산분석, 다중회귀분석을 통해 다음과 같은 결론을 얻었다. 첫째, 사상체질과 성격유형에서 외향성은 개인종목과 대인종목이 높은 반면, 단체종목은 내향성이 높았으며, 신체자신감은 대인종목이 신체능력 효능감과 자기표현 효능감이 높았다. 둘째, 외향성과 인식형의 성격유형은 태음인과 소양인이 높고, 내향성과 판단형은 소음인의 체질이 높았으며, 신체능력 효능감은 소음인의 체질이 높았다. 운동유형별로 개인종목, 단체종목, 대인종목은 다양한 성격유형이 사상체질에 따라 차이가 있었으며, 신체능력 효능감은 개인종목과 단체종목에서 사상체질에 따라 차이가 있었다. 셋째, 성격유형의 감각형과 직관형은 신체능력 효능감에 영향을 미치며
This thesis will investigate the potential use of effective negative space to improve the readability of text typography in graphic design. Negative space in two-dimensional design is also referred to as "white space" -- which is void of text or graphics. Negative space is more than just the background of a design. This thesis will demonstrate negative space as an element of design itself and develop a systematic approach to address negative space as it occurs in the following: margins, backgrou
