Video copy detection methods have emerged in recent years for a variety of applications. However, the lack of efficiency in the usual retrieval systems restricts their use. In this paper, we propose a parallel implementation strategy for content based video copy detection (CBCD) by using a multi-core processor. This strategy can support video copy detection effectively, and the processing time tends to decrease linearly as the number of processors increases. Experiments have shown that our approach is successful in speeding up computation and as well as in keeping the performance.

본 연구는 화장품 브랜드의 가치 유형에 따라 가장 효과적인 광고 카피 전략을 제시하고자 하였다. 이를 위해 3(브랜드가치)×3(카피유형) 요인설계를 사용하여 실험연구를 진행하였다. 연구결과 첫째, 럭셔리 브랜드의 경우, 독백형 카피가 가장 광고효과(광고태도와 구매의도)가 높게 나타났다. 둘째, 프리미엄 브랜드의 경우, 권유형 카피가 가장 광고태도가 높게 나타났다. 그러나 구매의도에서는 유의미한 차이가 없었다. 셋째, 매스 브랜드의 경우 대화형 카피가 가장 광고효과(광고태도와 구매의도)가 높게 나타났다. 이러한 결과는 화장품 브랜드의 가치 유형에 따라 카피를 유형을 차별화하여 사용하는 것이 효과적이라는 이론적 근거를 제공하였으며, 화장품 광고를 제작하는 실무자에게 카피 전략에 활용될 것이다.

본 연구는 브랜드 이미지와 모델 이미지 일치여부에 따른 화장품 광고효과와 브랜드 이미지와 광고 카피 간을 조화롭게 지각하느냐 여부에 따른 화장품 광고효과를 알아봄으로써, 화장품 광고에서 맥락효과를 검증하고자 하였다. 이를 위해 브랜드 가치유형(3)×광고카피유형(3) 요인설계를 이용하여 자료를 수집하였다. 연구결과 첫째, 화장품 브랜드 이미지와 모델 이미지의 일치여부에 따른 광고효과를 확인한 결과, 모델의 이미지와 브랜드의 이미지가 일치할 때 광고태도와 구매의도가 모두 유의미하게 높은 것으로 나타났다. 둘째, 화장품 브랜드 이미지와 카피유형의 일치도 지각여부에 따라 광고효과에서 차이가 있는 가를 확인하였다. 그 결과 화장품 브랜드 이미지와 카피유형이 일치한다고 지각하는 소비자들이 불일치한다고 지각하는 소비자에 비해 광고태도와 구매의도가 모두 유의미하게 높은 것으로 나타났다. 향후 화장품 광고 카피 전략을 세울 때맥락효과를 접목하여 카피전략을 세워야 하는가에 대한 타당성을 제공해 줄 것으로 기대된다.

공익광고의 효과적인 커뮤니케이션 수행에 어려움이 많고, 고도의 독창성이 요구되고, 대다수의 공익광고에서 은유적 표현이 빈번히 사용되어짐에도 불구하고, 이와 관련된 연구가 미비한 실정이다. 이에 본 연구는 공익광고의 은유적 표현의 효과에 대한 실증연구를 통해 은유적 광고전략에 도움을 주고자 하였다. 그 결과 첫째, 긍정적 접근과 간접카피를 사용한 은유광고가 높은 감정적 태도에 효과를 가지는 것으로 나타났다. 둘째, 긍정적 접근과 간접카피를 동시에 사용하였을 때 정보원의 공신력과 디자인선호도는 높게 증가하였다. 셋째, 긍정적 접근과 부정적 접근, 직접카피와 간접카피에 따라 정보신뢰도에 유의한 차이가 없었고, 접근유형과 카피유형에 따라 상호작용효과도 발생하지 않는 것으로 나타났다. 넷째, 간접카피를 사용한 광고가 행동의도에 효과를 가지는 것으로 나타났다. 따라서 공익광고의 효과를 높이기 위해서는 은유광고를 긍정적 접근으로 만드는 전략을 사용하여야 함을 본 연구결과는 시사하고 있다.

This paper presents the voltage source type half bridge lossless auxiliary inductor snubber assisted series capacitor compensated resonant high frequency inverter for induction heated fixing roller in copy machines. This high-frequency inverter treated here can completely achieve zero current soft switching (ZCS) commutation for wide power regulation range under its constant frequency pulse density modulation (PDM) scheme. Its transient and steady-state operating principle is originally presented fur a constant frequency PDM control strategy under a ZCS operation commutation, together with its output effective power regulation characteristics-based on the PDM strategy. The experimental operating performances of this ZCS-PDM high frequency inverter using IGBTs are illustrated as compared with computer simulation ones. Its power losses and actual efficiency are evaluated and discussed on the basis of simulation and experimental results.

The study explores the evolving landscape of overseas expansion strategies by Korean corporations, focusing on recent geopolitical tensions, the COVID-19 pandemic, and disruptions in global supply chains. It emphasizes the challenges faced by industries producing high-value products and delves into the concept of "Friend-Shoring" policies in the United States, leading major Korean companies to invest in local semiconductor, battery, and automotive factories. Recognizing the potential fragmentation of Korea's manufacturing sector, the paper introduces the "Mother Factory" strategy as a policy initiative, inspired by Japan's model, to establish core production facilities domestically. The discussion unfolds by examining the cases of major companies in Japan and the United States, highlighting the need for Korea to adopt a mother factory strategy to mitigate risks associated with friend-shoring policies. Inspired by Intel's "Copy Exactly" approach, the paper proposes a Korean mother factory model integrating smart factory technology and digital twin systems. This strategic shift aims to enhance responsiveness to geopolitical challenges and fortify the competitiveness of Korean high-tech industries. Finally, the paper proposes a Korean Mother Factory based on smart factory concepts. The suggested model integrates smart factory technology and digital twin frameworks to enhance responsiveness and fortify competitiveness. In conclusion, the paper advocates for the adoption of a comprehensive Korean Mother Factory model to address contemporary challenges, foster advanced manufacturing, and ensure the sustainability and competitiveness of Korean high-tech industries in the global landscape. The proposed strategy aligns with the evolving dynamics of the manufacturing sector and emphasizes technological advancements, collaboration, and strategic realignment.

This paper presents the two lossless auxiliary inductors-assisted voltage source type half bridge (single ended push pull: SEPP) series resonant high frequency inverter for induction heated fixing roller in copy and printing machines. The simple high-frequency inverter treated here can completely achieve stable zero current soft switching (ZCS) commutation for wide its output power regulation ranges and load variations under its constant high frequency pulse density modulation (PDM) scheme. Its transient and steady state operating principle is originally described and discussed for a constant high-frequency PDM control strategy under a stable ZCS operation commutation, together with its output effective power regulation characteristics-based on the high frequency PDM strategy. The experimental operating performances of this voltage source SEPP ZCS-PDM series resonant high frequency inverter using IGBTs are illustrated as compared with computer simulation results and experimental ones. Its power losses analysis and actual efficiency are evaluated and discussed on the basis of simulation and experimental results. The feasible effectiveness of this high frequency inverter appliance implemented here is proved from the practical point of view.

cDNA microarray-based comparative genomic hybridization(CGH) data includes low-intensity spots and thus a statistical strategy is needed to detect subtle differences between different cancer classes. In this study, genes displaying a high frequency of alteration in one of the different classes were selected among the pre-selected genes that show relatively large variations between genes compared to total variations. Utilizing copy-number changes of the selected genes, this study suggests a statistical approach to predict patients' classes with increased performance by pre-classifying patients with similar genetic alteration scores. Two-stage logistic regression model(TLRM) was suggested to pre-classify homogeneous patients and predict patients' classes for cancer prediction; a decision tree(DT) was combined with logistic regression on the set of informative genes. TLRM was constructed in cDNA microarray-based CGH data from the Cancer Metastasis Research Center(CMRC) at Yonsei University; it predicted the patients' clinical diagnoses with perfect matches (except for one patient among the high-risk and low-risk classified patients where the performance of predictions is critical due to the high sensitivity and specificity requirements for clinical treatments. Accuracy validated by leave-one-out cross-validation(LOOCV) was 83.3% while other classification methods of CART and DT performed as comparisons showed worse performances than TLRM.

The purpose of this study was to examine the effects of T-shirts product type and apparel benefit on consumer preference and purchasing intention. Data for the study were obtained by $3\times2$ mixed factorial design. The subjects were two hundred and thirty college male and female students. The data were analysed by factor analysis, cluster analysis, and ANOVA by using the SPSS program. The results of this study indicated that benefit did not have effects on consumers purchasing intention but significant influences on consumer preference for brand-parody products. For brand-copy products, benefit influenced the purchasing intention, and did not influence the consumer preference. This study suggested that new fashion trends, in association with consumer's benefit, have effects on consumer's purchasing behavior. The result of this study is likely to be useful in planning marketing strategy related to product type and new fashion trends.
