This study focuses on enhancing multilingual web content readability, particularly in Korean-to-Chinese translation, while maintaining font consistency. The developed system utilizes OCR technology to extract text from Korean web pages, automatically translates it into Chinese a translation API, and recommends suitable Chinese fonts based on a clustering-based similarity method. This approach aims to preserve the original design intent and information delivery while optimizing readability. It offers practical advantages and contributes to improving communication efficiency and user satisfaction in multilingual digital environments.
감정 욕구와 콘텐츠 선호 유형이 시청자와 유권자의 행동에 미치는 영향

Objectives This study explores consumer psychological tendency, content preference, and terrestrial broadcasting as antecedents of voting behaviors. Methods Using survey research, proposed hypotheses are investigated. Results First, need for emotion, the psychological variable, influenced content value and content playfulness positively. However, need for emotion did not affect consumption of terrestrial broadcasting directly. Content playfulness increased the degree of terrestrial broadcasting consumption. Content values did not influenced the degree of terrestrial broadcasting consumption. This means that people who prefer playful content consume terrestrial broadcasting. In addition, preference of content values and playfulness influenced voting intention positively, and lead to mobilization of voters. Lastly, people who are heavy users of terrestrial broadcasting show low voting intention of the presidential election. Discussion These results provide academic implications regarding effects of media variables on voting intentions, and provide explanation of mediating roles of terrestrial broadcasting between content variables and voting intention.

<P>Binary organic photovoltaics (OPVs) fabricated by single-step (SS) deposition of a binary blend of polymer (or small molecule) donor and fullerene acceptor (SS binary OPV) are widely utilized. To improve the OPV performance, SS ternary OPVs utilizing a ternary blend consisting of two (or one) electron donor(s) and one (or two) electron acceptor(s) have been studied. SS ternary OPVs require more sensitive and complex optimization processes to optimize bulk heterojunctions with bicontinuous nanoscale phase separation of the donor and acceptor. We demonstrated a novel ternary OPV fabricated by sequential (SQ) deposition of a single polymer donor and a binary mixture consisting of a phenyl-C<SUB>71</SUB>-butyric acid methyl ester (PCBM) and nonfullerene acceptor, 3,9-bis(2-methylene-(3-(1,1-dicyanomethylene)-indanone))-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno[2,3-<I>d</I>:2,3′-<I>d</I>′]-<I>s</I>-indaceno[1,2-<I>b</I>:5,6-<I>b</I>′]dithiophene (ITIC). In the SQ ternary OPV, PCBM effectively created a bicontinuous pathway for charge transport with a polymer, and ITIC mainly enhanced light absorption and photovoltage. This complementary effect was not observed in an SS ternary OPV utilizing the same donor and acceptors. Due to these complementary effects, the SQ ternary OPV exhibited a power conversion efficiency of 6.22%, which was 52 and 37% higher than that of the SQ binary OPV and the SS ternary OPV, respectively. In addition, the thermal stability of the SQ ternary OPV was found to be superior to that of the SS ternary OPV.</P> [FIG OMISSION]</BR>

Three dimensional (3D) porous structures consisting of Cu@CoO core-shell-type nano-dendrites were synthesized and tested as the anode materials in lithium secondary batteries. For this purpose, first, the 3D porous films comprising Cu@Co core-shell-type nano-dendrites with various thicknesses were fabricated through the electrochemical co-deposition of Cu and Co. Then the Co shells were selectively anodized to form Co hydroxides, which was finally dehydrated to get Cu@CoO nanodendrites. The resulting electrodes exhibited very high reversible specific capacity almost 1.4~2.4 times the theoretical capacity of commercial graphite, and excellent capacity retention (~90%@50<SUP>th</SUP> cycle) as compared with those of the existing transition metal oxides. From the analysis of the cumulative irreversible capacity and morphology change during charge/discharge cycling, it proved that the excellent capacity retention was attributed to the unique structural feature of our core-shell structure where only the thin CoO shell participates in the lithium storage. In addition, our electrodes showed a superb rate performance (70.5%@10.8 C-rate), most likely due to the open porous structure of 3D films, large surface area thanks to the dendritic structure, and fast electron transport through Cu core network.

주의력결핍 과잉행동장애(Attention Deficit Hyper activity Disorder, 이하 ADHD) 환아는 실행 기능 결함으로 일상생활 과업 수행에 어려움을 겪는다. ADHD 환아는 과업 수행 중 주의력을 유지하는 것뿐만 아니라 과업을 끝까지 지속하는 것에 어려움이 있어, 과업 실패가 잦다. 본 연구에서는 ADHD 환아가 일상생활 과업을 끝까지 완성할 수 있게 도와주는 실행기능 보조 도구 보이스 컴패니언봇 디자인 과정을 다루고 있다. 보이스 컴패니언봇이 디지털 치료제적 가치와 사용자 친화적 가치를 동시에 충족할 수 있도록 아래 3 가지 내용을 시나리오 디자인에 반영하였다. 첫째, 기본 대화 구조로 자기 지시 훈련 단계인 ‘목표 정하기(Goal), 계획 세우기(Plan), 실행하기(Do), 점검하기(Check)’ 구조를 반영한다. 둘째, 3 가지 스캐폴딩 전략이 세부 스크립트에 반영되었다. 셋째, 스크립트를 Google Dialogflow 환경에 적용하는 7 가지 디자인 과정을 거쳤다. 본 연구에서 제시한 개발 과정은 향후 VUI 제품 디자인 과정에 적용될 수 있음을 기대한다. 더불어 개발한 보이스 컴패니언봇은 ADHD 환아에게 디지털 치료제로 사용될 수 있으리라 기대한다.
