MengYao Wang,한석원 사단법인 한국융합기술연구학회 2024 아시아태평양융합연구교류논문지 Vol.10 No.8

2020년 COVID-19 팬데믹 현상으로 인해 언택트(Untact) 환경이 사회의 필수 요소로 자리 잡으면서 메타버스 기술의 발전이 가속화되었다. 메타버스 배경에서 어린이 그림책은 점차 전통적인 종이 매체에서 스마트폰과 태블릿과 같은 디지털 이동 단말기로 전환되고 있다. 새로운 미디어 기술을 활용한 어린이 그림책은 시각적 정보 전달뿐만 아니라 청각, 촉각 등 다양한 형태의 상호작용을 제공하여 현실 세계와 증강 현실 세계의 경험을 풍부하게 한다. 인공지능 시대 2010년 이후 출생한 '디지털 원주민'인 알파세대는 자연스럽게 메타버스 환경에 적응하면서, 이들의 디지털 사용 환경, 생활 패턴, 독서 습관 등에 큰 변화를 가져왔다. 본 연구는 메타버스 배경에서 그림책의 변화와 발전을 탐구하는 것을 목적으로 알파세대 어린이의 특성, 독서 특성 및 메타버스 그림책의 구성 요소, 시각적 내러티브, 상호작용성을 초점으로 초기 연구를 수행하였다. 그리고 메타버스 그림책 대표 사례 연구를 통해 그들의 관심사와 흥미, 심리적 성향을 반영할 수 있는 메타버스 기반 그림책 확대를 도모하였다. 연구 결과, 알파세대 메타버스 기반 그림책에 대한 다중 감각과 몰입형 경험을 통해 현실 공간에서는 불가능한 참신한 창작, 시각화 및 체험 방식을 실현하게 되었다. 본 연구는 알파세대 새로운 그림책 디자인의 방향을 제시하였다는 데 의의가 있으며, 앞으로 알파세대의 메타버스 그림책 교육이 미래 교육의 새로운 분야가 될 것으로 전망한다. The COVID-19 pandemic in 2020 has established the untact environment as a crucial element of society, thereby accelerating the advancement of metaverse technology. Within the metaverse context, children's picture books are progressively transitioning from traditional paper formats to digital mobile devices such as smartphones and tablets. Picture books that leverage new media technologies provide visual information and various forms of interaction, including auditory and tactile experiences, thereby enriching the experience in the real world and augmented reality environments. The Alpha generation, born after 2010 and regarded as "digital natives" in the age of artificial intelligence, is naturally adapting to the metaverse environment, leading to significant changes in their digital usage patterns, lifestyle habits, and reading behaviors. This study explores the changes and developments in picture books within the metaverse framework, focusing on the characteristics of Alpha generation children, their reading habits, and the elements of metaverse picture books, such as visual narratives and interactivity. Furthermore, through case studies of representative metaverse picture books, this research seeks to promote the expansion of metaverse-based picture books that align with interests, curiosities, and psychological tendencies. The findings suggest that metaverse-based picture books for the Alpha generation enable novel forms of creation, visualization, and immersive experiences that are impossible in the physical world. This study is significant in that it proposes new directions for designing picture books for the Alpha generation and anticipates that metaverse picture book education will emerge as a new domain in future educational practices.

Cyclooxygenase-2 Polymorphisms and Susceptibility to Colorectal Cancer: A Meta-Analysis

Jun Wang,Xufeng Guo,Jixiang Zhang,Jia Song,Mengyao Ji,Shijie Yu,Jing Wang,Zhuo Cao,Weiguo Dong 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.6

Purpose: Four polymorphisms, -765G>C, -1195G>A, 8473T>C, and Val511Ala, in the cyclooxygenase-2 (COX-2) gene were identified to be associated with colorectal cancer (CRC) risk. However, the results are inconsistent. The objective of this meta-analysis was to evaluate the association between these four polymorphisms and the risk of CRC. Materials and Methods: All eligible case-control studies published up to December 2012 on the association between the four polymorphisms of COX-2 and CRC risk were identified by searching PubMed and Web of Science. The CRC risk associated with the four polymorphisms of the COX-2 gene was estimated for each study by odds ratio (OR) together with its 95% confidence interval (CI), respectively. Results: A total of 15 case-control studies were included. Overall, no evidence has indicated that the -1195A allele, -765C allele, 8473C allele, and 511Ala allele are associated with susceptibility to CRC (-1195G>A: OR=1.11, 95% CI: 0.82-1.51, p=0.78; -765G>C: OR=1.08, 95% CI: 0.96-1.21, p=0.07; 8473T>C: OR=1.03, 95% CI: 0.89-1.18, p=0.91; Val511Ala:OR=0.71, 95% CI: 0.46-1.09, p=0.94). However, stratified analysis with ethnicity indicated that individuals with -765GC or GC/CC genotypes had an increased risk of CRC among Asian populations (GC vs. GG: OR=1.05, 95% CI: 0.87-1.28, p=0.03; GC+CC vs. GG: OR=1.08, 95% CI: 0.96-1.21, p=0.07). Conclusion: This meta-analysis indicated that -765G>C polymorphism was significantly associated with susceptibility to CRC in Asian populations.

Head-to-Head Linked Dialkylbifuran-Based Polymer Semiconductors for High-Performance Organic Thin-Film Transistors with Tunable Charge Carrier Polarity

Shi, Shengbin,Wang, Hang,Uddin, Mohammad Afsar,Yang, Kun,Su, Mengyao,Bianchi, Luca,Chen, Peng,Cheng, Xing,Guo, Han,Zhang, Shiming,Woo, Han Young,Guo, Xugang American Chemical Society 2019 Chemistry of materials Vol.31 No.5

<P>A planar backbone conformation is essential for enabling polymer semiconductors with high charge carrier mobility in organic thin-film transistors. Benefiting from the smaller van der Waals radius of the O atom in furan (versus the S atom in thiophene), alkylated furan exerts a reduced steric hindrance on neighboring arene, and it was found that the head-to-head (HH)-linked 3,3′-dialkyl-2,2′-bifuran (<B>BFR</B>) can attain a high degree of backbone planarity. Hence, <B>BFR</B> should be a promising building block for constructing polymer semiconductors with a planar backbone conformation and hold distinctive advantages over a dialkylbithiophene-based analogue, which is typically highly twisted. The alkyl chains on the 3 and 3′ positions offer good solubility to the resulting polymers, which in combination with its planar backbone yields an improved molecular design window for developing high-performance polymer semiconductors, particularly those with a simple molecular structure and based on the acceptor co-unit without any solubilizing chains. When incorporated into polymer semiconductors, remarkably high hole and electron mobilities of 1.50 and 0.31 cm<SUP>2</SUP> V<SUP>-1</SUP> s<SUP>-1</SUP> are obtained for <B>BFR</B>-based polymers <B>FBFR-BO</B> and <B>CNBFR-C18</B> containing fluorinated and cyano-functionalized benzothiadiazole as the acceptor co-unit, respectively. Such mobilities are the highest values for HH-linked polymers and also among the best for furan-containing polymers. The results demonstrate that HH-linked dialkylbifuran is a highly promising building block for constructing organic and polymeric semiconductors, and this new approach by incorporating HH <B>BFR</B> offers several distinctive advantages for developing high-performance polymer semiconductors, including effective optoelectronic property tuning using a minimal number of aromatic rings, reduced structural complexity, facile material synthesis, good material solubility, and enriching the material library. In addition, the study offers important guidelines for future development of furan-based polymers and head-to-head linkage containing organic semiconductors.</P> [FIG OMISSION]</BR>

김희정,YANG MENGYAO,권나현,조문연,HAN JINGJING,Wang Rui,Qi Sujie,Li Haidong,Nguyen Van‐Nghia,Li Xingshu,Cheng Hong‐Bo,윤주영 대한화학회 2023 Bulletin of the Korean Chemical Society Vol.44 No.3

Noninvasive treatments for terminal cancer patients constitute a new trend in tumor treatment. Therefore, phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), has attracted considerable interest. Light and a photosensitizer (PS) are employed in both treatment methods. For PDT, the PS generates reactive oxygen species (ROS) when exposed to light, whereas for PTT, the PS generates heat. In this regard, the systematic design of new PSs has become an active area of phototherapy research in an effort to solve the problems associated with conventional PSs. In the past decade, acti- vatable and heavy-atom-free PSs have become significant research areas. Therefore, we discuss our recent contributions to the PDT and PTT in this account.

Progressive Failure of Precast Shear Wall Structure for RC Composite Column Confined Uniform Hollow Panels under Cyclic Loading

Jianxing Sun,Mengyao Ci,Guangda Xu,Rucheng Wang,Weibin Ni,Zongmei Xu,Shao-Jie Wang 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.5

To increase the assembly construction efficiency of low-rise and multi-story buildings in rural areas, the precast shear wall for RC composite column confined uniform hollow panels was designed in this paper. The seismic performance and failure mechanism of the structure are studied by combining low cyclic load test with finite element and theoretical analysis. The study found that the connection between the components is safe. The structure has three progressive failure processes that are the interaction stage, composite column constrained dense column work stage and weak framework stage. The structure has good bearing and capacity of energy dissipation, and the ductility coefficient of the specimen is 2.89. In addition, the finite element model is established based on ABAQUS, and the damage evolution process of the structure is visually represented by the damage nephogram. In combination with test and simulation, calculation methods of shear capacity of the shear wall are established. The ratio of test value to calculated value in the interaction stage and weak framework stage is 1.14 and 1.06 respectively. The calculation method is reliable and has clear physical significance. The study can provide a reference for the application in low-rise and multi-story buildings.

Demand‐based charging strategy for wireless rechargeable sensor networks

Ying Dong,Yuhou Wang,Shiyuan Li,Mengyao Cui,Hao Wu 한국전자통신연구원 2019 ETRI Journal Vol.41 No.3

A wireless power transfer technique can solve the power capacity problem in wireless rechargeable sensor networks (WRSNs). The charging strategy is a widespread research problem. In this paper, we propose a demand‐based charging strategy (DBCS) for WRSNs. We improved the charging programming in four ways: clustering method, selecting to‐be‐charged nodes, charging path, and charging schedule. First, we proposed a multipoint improved K‐means (MIKmeans) clustering algorithm to balance the energy consumption, which can group nodes based on location, residual energy, and historical contribution. Second, the dynamic selection algorithm for charging nodes (DSACN) was proposed to select on‐demand charging nodes. Third, we designed simulated annealing based on performance and efficiency (SABPE) to optimize the charging path for a mobile charging vehicle (MCV) and reduce the charging time. Last, we proposed the DBCS to enhance the efficiency of the MCV. Simulations reveal that the strategy can achieve better performance in terms of reducing the charging path, thus increasing communication effectiveness and residual energy utility.
