Improved adhesion of metal–polymer sandwich composites using a spontaneous polymer grafting process

SJR Q2Functional Composites and StructuresOA

Abstract Improving adhesion at the metal–polymer interface is a critical issue for metal–polymer sandwich composites. Herein, we report an efficient way to increase the adhesion via grafted organic layers. A redox activation process was used to graft organic layers to steel surfaces using 4-para-nitrobenezenediazonium (NBD) salt and L-ascorbic acid (LAA). Successful formation of a grafted organic layer was confirmed by microstructural analysis and its performance as an adhesion primer was evalua

수원 화성 과학 탐방을 통한 문화재에 대한 과학적 안목 형성 지도
최재혁, 박승재

한국 역사 속 과학탐방은 1998년부터 개발, 시행되고 있다. 한국 역사 속 과학 탐방의 효과에 대해서는 일부 논의가 있었으나, 실질적인 연구는 부족하였다. 이 연구에서는 한국 역사 속 과학탐방의 목적을 문화재에 대한 과학적 안목 형성 관점에서 화성 과학탐방의 사례와 함께 논의하였다. 문화재의 과학적 우수성 평가 준거를 고려하여 연구자의 안내된 질문과 수렴적 및 발산적 과학 탐구로 구성된 화성(華城) 과학 탐방 자료가 개발되고 지도 방략이 구안되었다. 본 연구에서는 문화재의 과학적 우수성 평가 준거를 고려한 화성 과학 탐방을 지도하여 중학생들이 문화재의 과학적 우수성을 올바로 평가할 수 있는 분별 능력, 즉 문화재에 대한 과학적 안목을 형성하는지 여부를 조사 하고자 하였다. 서울 지역 중학교 과학 특별활동반 10명을 연구 대상으로 하였다. 탐방 전과 후에 실시된 '문화재의 과학적 우수성 평가하기' 설문과 탐방 후 면담을 통해 탐방을 통한 관점 변화를 분석하여 과학 탐방 활동으로 문화

We constructed a neutron calibration facility based on a 300-mCi Am-Be source in conjunction with a search for weakly interacting massive particle candidates for dark matter. The facility is used to study the response of CsI(Tl) crystals to nuclear recoils induced by neutrons from the Am-Be source and comparing them with the response to electron recoils produced by Compton scattering of 662-keV $\gamma$-rays from a $^{137}$Cs source. The measured results on pulse shape discrimination (PSD) betwe

Machine learning-assisted modelling of stress concentration factor of unidirectional fiber composites for predicting their tensile strength
Jae‐Hyuk Choi, Wonjin Na, Woong‐Ryeol Yu
SJR Q2Modelling and Simulation in Materials Science and Engineering

Abstract Significant variations in the tensile strength of unidirectional (UD) fiber-reinforced composites are frequently observed due to randomness in the fiber arrays. Herein, we propose a novel method for predicting tensile strength capable of quantifying uncertainty based on a new recurrence relation for fiber fracture propagation and a determination algorithm for the fracture sequence for random fiber arrays (RFAs). We performed finite element simulations, calculating the stress concentrati

3.11 이후, 무라카미 다카시의 변화하는 슈퍼플랫
최재혁

무라카미 다카시는 ‘슈퍼플랫’ 개념을 제기하며 재패니즈 네오 팝 미술로 세계적인 성공을 거둔 현대미술가다. 슈퍼플랫은 현대 일본의 애니메이션과 전근대 일본미술을 ‘평면성’이라는 공통항으로 묶어낸 조형적 개념인 동시에, 고급문화와 대중문화의 위계가 애매해지고 계급과 취향도 해체되어 ‘평평해진’ 전후 일본 사회에 대한 독법으로 의미를 확장해 갔다. 무라카미는 2011년 동일본 대지진 이후 종교와 철학으로 회귀하고 ‘인간의 무력함과 예술의 가능성’과 같은 진중한 테마로 전환했다는 평가를 받고 있다. 동양의 고전적 주제인 사신도의 구성을 취한 <오백나한도>는 에도 후기 화가들의 표현에서 다방면으로 취합한 도상을 변형을 걸쳐 도입함으로써 ‘오타쿠 시대’가 종언되었음을 알리며 작가를 전통미술의 현대적 체현자로도 자리매김하는 계기가 되었다. 그러나 캐릭터화된 대상 묘사가 화면에 잔존하고 있다는 측면에서 무라카미에게 오타쿠 문화는 여전히 주요한 제작 동인이었다. 과거 예술로 받아들여지지 않던 일본
