Conductive polymeric composites (CPC) incorporating carbon nanotubes (CNT) and carbon fibers (CF) offer promising potential in self-heating applications due to their superior electrical and thermal properties. This study investigates the synergistic effects of CNT and CF on the electrical conductivity and heat-generation capabilities of CNT/polydimethylsiloxane (PDMS) nanocomposites. Three CF lengths (0.1 mm, 3 mm, and 6 mm) were systematically evaluated to establish hierarchical conductive networks. The incorporation of 6 mm CF into CNT/PDMS composites resulted in a 72% increase in electrical conductivity compared to composites with 0.1 mm CF. Despite these enhancements in electrical performance, the heat-generation capabilities, based on simulations and experimental validation, showed minimal dependence on CF length. A micromechanics-based numerical approach was used to compare and validate the experimental findings, identifying limitations in current analytical models, especially in predicting the heat-generation behavior.

Lithium (Li) metal is a promising anode for next-generation batteries due to its high capacity, low redox potential, and low density. However, dendrite growth and interfacial instability limit its use. In this study, an artificial solid electrolyte interphase layer of LiF and Li-Sn (LiF@Li-Sn) was fabricated by spray-coating SnF2 onto Li. The LiF@Li-Sn anode exhibited improved air stability and electrochemical performance. Electrochemical impedance spectroscopy indicated a charge transfer resistance of 25.2 Ω after the first cycle. In symmetric cells, it maintained a low overpotential of 27 mV after 250 cycles at 2 mA/cm2, outperforming bare Li. In situ microscopy confirmed dendrite suppression during plating. Full cells with NMC622 cathodes and LiF@Li-Sn anodes delivered 130.8 mAh/g with 79.4% retention after 300 cycles at 1 C and 98.8% coulombic efficiency. This coating effectively stabilized the interface and suppressed dendrites, with promising implications for practical lithium metal batteries.

본 연구는 국제경영전략 관점에서 해외자회사가 이전한 지식은 기업 경쟁력 강화에 언제나 긍정 적일 것이라는 가정을 비판하기 위해, 해외자회사의 역지식이전 수준과 기업성과 간 관계를 분석하 였다. 글로벌 기업 직원 256명을 대상으로 설문조사한 결과, 해외자회사가 본사로 이전한 지식 수 준이 높을수록 높은 기업성과를 보이는 것으로 나타났다. 그러나 이러한 효과는 해외자회사의 역량 및 해외자회사와 본사 간 비전공유 수준에 따라 차이를 보이는 것으로 나타났으며, 해외자회사의 역량이 낮거나, 비전공유 수준이 낮은 조직의 역지식이전은 기업성과에 부정적 영향을 제공하는 것 으로 나타났다. 이를 통해 본 연구는 역지식이전 과정에서 글로벌 기업의 형태적 통제기제와 사회 적 통제기제가 요구되고 있음을 제시하였다.

This study aims to examine how the marketing characteristics of Wanghong (Chinese internet influencers) influence Chinese consumer attitudes and purchase intentions toward fashion products. Specifically, it investigates how the factors of expertise, trustworthiness, and attractiveness play a critical role in shaping consumer behavior in the digital marketing landscape. The study employed a survey-based quantitative approach, collecting data from 272 Chinese consumers engaging regularly with Wanghong marketing content. A structured questionnaire using a 5-point Likert scale was developed, incorporating validated measurement items from previous studies. The collected data were then analyzed using exploratory factor analysis, correlation analysis, and multiple regression analysis. The findings indicate that while expertise negatively influences consumer attitudes, trustworthiness and attractiveness have a positive impact. Furthermore, trustworthiness and attractiveness were found to significantly enhance purchase intention, while expertise was found to have no significant effect. Additionally, the findings showed that consumer attitudes toward Wanghong-mediated marketing play a mediating role in the relationship between Wanghong characteristics and purchase intention, with the results suggesting that consumers perceive highly knowledgeable Wanghong as distant or overly commercial, reducing their willingness to engage. In contrast, Wanghong who exhibit trustworthiness and personal appeal are more effective in driving consumer interest and purchases. These findings provide valuable insights for fashion brands aiming to optimize influencer marketing strategies in China, emphasizing the importance of relationship-driven and authenticity-focused marketing.

이 연구는 글로벌화의 관점에서 한국의 부산국제영화제와 중국의 상하 이국제영화제 포스터 디자인을 비교 분석한 것이다. 문화 상징과 색채 사용을 중심으로 두 국가 영화제 포스터의 브랜드 이미지 구축과 문화적 표현의 차이를 탐구한다. 본 연구는 이론적 틀로 Schmitt의 전략적 경험 모듈(SEMs)을 활용하고, 정량적 색채 분석을 위해 한국표준색채분석 (KSCA) 프로그램을 도입하여 시각적 상징이 어떻게 문화적 상징성과 감 성적 공감을 전달하는지 살펴본다. 연구 결과, 부산영화제 포스터는 한색 계열을 선호하여 이성적이고 미니멀한 현대 미학을 반영하고 있으며, 상 하이영화제 포스터는 난색 계열과 풍부한 문화적 상징을 통해 강한 국가 정체성과 감성적 매력을 전달하고 있음을 알 수 있다. 이 연구는 글로벌 화의 맥락에서 한국과 중국 영화제의 브랜드 포지셔닝 및 디자인 전략의 차별성을 강조하며, 국제 영화제 포스터에 문화 상징을 적용하는 것에 대한 이론적 통찰과 실질적인 참고 자료를 제공한다.

이 연구는 중국과 한국 주요 영화제인 베이징 국제영화제와 전주 국제 영화제 포스터의 색채 디자인과 문화적 상징성에서 나타나는 문화 간 차 이를 탐구한다. IMAGE COLOR SUMMARIZER와 한국 표준 색채 분석 (KSCA) 프로그램을 활용하여 색채가 감정 표현과 문화적 상징성에서 차 지하는 역할을 정량적 및 정성적으로 분석하였다. 연구 결과, 한국 포스 터는 차가운 색조와 미니멀한 디자인을 선호하여 이성적 미학을 강조하 는 반면, 중국 포스터는 따뜻한 색조와 전통적인 요소를 사용하여 문화 적 풍부함과 국제적 매력을 전달하는 것으로 나타났다. Schmitt의 감각 경험 이론을 통해 본 연구는 브랜드 구축과 문화적 커뮤니케이션에서 독 특한 시각적 전략을 강조하며, 문화 간 시각 커뮤니케이션 연구에 기여 하고자 한다.

This study focuses on the effectiveness of regional business support programs funded by South Korea's Balanced National Development Special Account, one of the policies designed to address regional imbalances and promote local autonomy. Using the analytical approach including DEA (Data Envelopment Analysis) methodology, This study analyzed the efficiency of 76 star companies in the Jeonbuk region based on their performance from 2018 to 2023. This study was designed to improve previous studies limitations, which only analyzed simple input-output efficiency in the short term, by using six years of mid-term data to comprehensively evaluate input variables in both R&D and Non-R&D sectors. The main purpose of this study is to analyze the effectiveness of the expiring Star Company Development Program by evaluating efficiency of supported company groups using DEA and to propose support models and policy suggestions for upcoming regional specialized industries support program by identifying the features of both optimal and inefficiency models. For this, employments along with financial indicators such as sales revenue, operating profit, and total assets were set as output variables, with R&D and non-R&D support amounts were set as input variables for analysis. According to the results, the optimal efficiency model group has strong intellectual property acquisition capabilities, and continuous R&D investment. It shows that continuous innovation activities are a key factor for improving the effectiveness of support. This study found that, from a mid․long term perspective, policy support programs should be customized by unique characteristics of each industry field, Based on this, it was suggested that upcoming regional specialized industry support programs in the Jeonbuk region should include policy planning and support program design to complement the weaknesses of each industry field.
