The Localization Effect of Online Advertising: An Evidence from the Movie Market
Kim,Jongdae(Jongdae Kim),Lee,Youseok(Youseok Lee),Seok,Junhee(Junhee Seok) 한국상품학회 2024 商品學硏究 Vol.42 No.1
This study introduces a novel deep learning-based framework designed to evaluate the impact of localization in online advertising within the film industry. Particularly, the authors consider movie poster images as an advertising tool. Employing an image-based deep learning technique, the study extracts and quantifies visual information to assess poster localization levels. Then, we estimate the effect of poster localization on the movie’s financial performance in a foreign market. The results reveal that the localization effect follows the U-shaped curve, implying that the relevant level of poster localization should be in two ways: either fully non-localized or extremely localized. We expect this research to contribute by proposing the empirical framework to not only explore the effect of online advertising in the service business, but also assess the effect of the international advertising strategy from the perspective of the movie poster localization. Moreover, we posit that this research has managerial implications in the sense that it can contribute to the decision-making process of the relevant level of localization and poster image modification.

<P><B>Abstract</B></P> <P>Chronic exposure to hydrophobic bile acids such as chenodeoxycholic acid (CDCA) and cholic acid (CA) in the liver during cholestasis causes hepatotoxicity and inflammatory response. However, the detailed mechanisms regarding the role of autophagy in cholestatic hepatotoxicity remain largely unknown. Here we determined autophagic clearance in livers of bile duct-ligated mice, in which bile acids accumulate, and in human hepatoma HepG2 cells treated with CDCA and CA. The accumulation of bile acids caused defective autophagic clearance, shown by the accumulation of insoluble p62 and ubiquitinated proteins and cell death accompanied by caspase-3 processing. Hepatocytes exposed to bile acids also showed the accumulation of autophagosomes via suppressed autophagy flux. Treatment of CDCA markedly suppressed Beclin-1 expression, which exhibits a higher cytotoxicity than CA. Moreover, pharmacological or genetic inhibition of autophagy enhanced bile acid-induced cell death. Finally, <I>in vivo</I>, bile duct ligation led to aberrant accumulation of p62 and ubiquitinated proteins in the liver. Our data demonstrate that inhibited autophagy is an essential component of liver injury during cholestasis.</P> <P><B>Highlights</B></P> <P> <UL> <LI> CDCA, CA and bile duct ligation caused defective autophagic clearance. </LI> <LI> CDCA suppressed Beclin-1 expression, which exhibits a higher cytotoxicity than CA. </LI> <LI> Pharmacological or genetic inhibition of autophagy enhanced bile acid-induced cell death. </LI> <LI> Reduced Beclin-1 expression may lead to higher cytotoxicity of CDCA. </LI> </UL> </P>
Downburst versus boundary layer induced wind loads for tall buildings
Kim, Jongdae,Hangan, Horia,Eric Ho, T.C. Techno-Press 2007 Wind and Structures, An International Journal (WAS Vol.10 No.5
Downbursts are transient phenomena that produce wind profiles that are distinctly different from synoptic boundary layers. Wind field data from Computational Fluid Dynamics (CFD) simulations of isolated downburst-like impinging jets, are used to investigate structural loads of tall buildings due to these high intensity winds. The base shear forces and base moments of tall buildings of heights between 120 and 250 m produced by downburst winds of various scales are compared with the forces from the equivalent boundary layer gust winds, with matched 10-metre wind velocity. The wind profiles are mainly functions of the size of the downburst and the radial distance from the centre of the storm. Wind forces due to various downburst profiles are investigated by placing the building at different locations relative to the storm center as well as varying the size of the downburst. Overall it is found that downbursts larger than approx. 2,000 m in diameter might produce governing design wind loads above those from corresponding boundary layer winds for tall buildings.
Effective Mapping and Scheduling for Multi-core Systems, by Using Iterative Zone Refinement
Jongdae Kim,Soohyun Kim,Hyunchul Shin 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
To solve computationally expensive problems, multiple processor SoCs (MPSoCs) are frequently used. Mapping of applications to MPSoC architectures and scheduling of tasks are key problems in system level design of embedded systems. In this paper, iterative zone refinement algorithm is described, in which the tasks in the active zone is simultaneously mapped and scheduled for heterogeneous MPSoC architectures. The tradeoff between run-time and quality of solution is possible by adjusting the number of tasks in the zone. Experimental results show that our method is very effective.

An Empirical Study on the Affective Commitment: Comparative Study of South Korea and the U.S.
( Kim Jongdae ),( Lee Wootae ) 경남대학교 산업경영연구소 2005 지역산업연구 Vol.28 No.3
Nowadays as human resource management has been improved to a strategic level, to attract and retain intellectual employees and effectively motivate them has become MNCs’ (Multinational Corporations) key to success. Therefore, how to improve the employees’ affective commitment under the cross-cultural background,and how to motivate them through effective incentive approaches to increase the MNCs’ performance have become a key step to success. The author conducted an empirical study on the relationship between incentive approaches and affective commitment, focusing on whether there exist affective commitment differences according to cross-culture differences in South Korea and the U.S. Hofstede’s cross-culture model was introduced in this thesis, and both theoretical and practical implications are discussed.
Determinants and Dimensions of Supply Chain Evolution Path
JongDae Kim,SangChun Lee 한국무역연구원 2016 貿易 硏究 Vol.12 No.1
Vertical integration, as well as outsourcing, are typical make or buy decisions and have beengiven attention in the academic area and among practitioners. Many previous studies havebeen done on the determinants of the span of process of a firm and the related choice ofappropriate governance structure. In turn, those decisions affect an appropriate structure ofsupply chain which continually evolves with environmental changes. In this study, we proposean evolution map of supply chains and groups of accelerators and decelerators whichaccelerate or decelerate the evolution of supply chains.In creating a supply chain evolution map, we define three dimensions of the evolution,namely, span of process, supplier base structure and inter-organizational relationship. Followingthese dimensions, we propose three stages for each dimension: full spectrum, core andoutsourcing and Micro-some for the first dimension, span of process. One-to-one, N-to-one andNo-to-N for the second dimension, supplier base structure.
