Recently, as interest in non-face-to-face experiences and services increases, the demand for web video contents that can be easily consumed using mobile devices such as smartphones or tablets is rapidly increasing. To cope with these requirements, in this paper we propose a technique to efficiently produce video contents that can provide experience of visiting famous places (i.e., stage tour) in animation or movies. To this end, an image dataset was established by collecting images of stage areas using Google Maps and Google Street View APIs. Afterwards, a deep learning-based style transfer method to apply the unique style of animation videos to the collected street view images and generate the video contents from the style-transferred images was presented. Finally, we showed that the proposed method could produce more interesting stage-tour video contents through various experiments.

This essay aims to examine chick lit written within the Asian American context. For the most part, the chick lit genre has been typically regarded as a site to study contemporary white women's experiences and to debate the genres' credentials as feminist literature. Though some may disagree, there is general consensus that chick lit has fallen out of vogue after reaching its peak in the first decade of the new millenium.; nevertheless, it is being revisited by readers and critics alike as it has recently re-emerged as a location upon which to examine how race and gender inform notions of national belonging and female subject formation in the twenty-first century. To this end, this essay reads Kim Wong Keltner's The Dim Sum of All Things (2004). Keltner's protagonist Lindsey Owyang is yet another twentysomething "chick" looking for love, self, independence, and success in the huge megalopolis of San Francisco. What sets Lindsey apart from the chick prototype is that she is a third-generation ABC (American-born Chinese) and issues relevant to Asian America frequently make their way into Lindsey's narrative. Though it is generally considered as standing a "few notches above the standard chick-lit fare" (Stover n. pag), I would argue that meaningful reflections on many of the major pillars of Asian American literature, history, and cultural politics are glossed over in favor of cursory musings about the daily vicissitudes of Lindsey's life. This essay thus takes to task Ferriss's claim that a "serious" consideration of chick lit "brings into focus many of the issues facing contemporary women and contemporary culture - issues of identity, of race and class, of femininity and feminism, of consumerism and self-image" (2). I contend that a close examination of Keltner's The Dim Sum of All Things discloses that the chick lit format undermines a "serious consideration" of Asian American issues by presenting in particular a highly problematic representation of race and of Asian American femininity.

In the glocal era, the competitiveness of local authorities leads to national competitiveness. Even though they have competitively adopted slogans to stay competitive, the process has not been systematic. The goal of this study is to provide basic data needed to develop and utilize urban brand slogans effectively. In terms of a research scope, 48 slogans currently in use by 24 local authorities of Gyeongsangbuk-do as of April 2020 were chosen. Concerning the lingual representation of such slogans, diverse languages such as Korean, English and Sino-Korean have been used. In terms of meaning of meaning and material type, there was a lack of coherence among the slogans. In addition, they were poor in representing identity, and abstract image upgrade types were commonly found. It is anticipated that the study results would make a contribution to the development of urban brand slogans and value generation.

This study presents methods and alternative examples for fashion brands to effectively use video-based communication channels to form brand identity that analyzes the definition, status and type of YouTube channel fashion films as well as enables the ability to derive brand identity characteristics. Literature studies focused on Christian Dior's official website and related previous studies. The temporal range of the case studies was from October 7, 2010, the date when the first fashion film was uploaded to current Christian Dior YouTube to July 17, 2020 (the survey date), and there are a total of 550 subjects for quantitative analysis. The succession of the couture spirit means that Christian Dior's craftsmanship was created and passed down by Musée Christian Dior to act as a contemporary key element of brand identity. The iconic expression of femininity is Dior's core design philosophy that began when the woman image of a new era was presented through a new look, and Dior's femininity means a woman that reflects the character of the times as is interpreted as her own personality from the perspective of modernism through the creative directors of future generations. The brand's core identity code 'Miss Dior' expresses the brand's vision and eternity through perfume as well as targets Z generation male consumers through an emotional approach based on forms that used emotional images such as movie-type films.

Existing license plate recognition system is used as an optical character recognition method, but a method of using deep learning has been proposed in recent studies because it has problems with image quality and Korean misrecognition. This requires a lot of data collection, but the collection of license plates is not easy to collect due to the problem of the Personal Information Protection Act, and labeling work to designate the location of individual license plates is required, but it also requires a lot of time. Therefore, in this paper, to solve this problem, five types of license plates were created using a virtual Korean license plate generation program according to the notice of the Ministry of Land, Infrastructure and Transport. And the generated license plate is synthesized in the license plate part of collectable vehicle images to construct 10,147 learning data to be used in deep learning. The learning data classifies license plates, Korean, and numbers into individual classes and learn using YOLOv5. Since the proposed method recognizes letters and numbers individually, if the font does not change, it can be recognized even if the license plate standard changes or the number of characters increases. As a result of the experiment, an accuracy of 96.82% was obtained, and it can be applied not only to the learned license plate but also to new types of license plates such as new license plates and eco-friendly license plates.

The post chamber in hybrid rocket is installed to induce additional increase in combustion enthalpy by allowing continuous burning of the liquefied fuels. When paraffin wax fuel is used, unsteady pressure oscillations are observed only at the beginning of combustion. This study intends to investigate the effect of additional combustion of liquefied fuel droplets on the occurrence of unsteady pressure fluctuations. For this, the combustion in post-chamber was visualized and image analysis using POD(Proper Orthogonal Decomposition) technique was performed. In addition, the hypothesis was proposed on the occurrence of unsteady pressure oscillations by identifying the modes including the behavior of droplets through mode reconstruction. Conducting a series of combustion tests, the amount of liquefied fuel flowing into the post chamber and the generation of fuel droplets were controlled. Also, the changes in frequency characteristic of unsteady pressure oscillation were monitored. As a result, the unsteady pressure oscillations observed in paraffin wax combustion were the result of additional combustion of fuel droplets generated in the post chamber.

Haze is a local weather phenomenon in which very small droplets float in the atmosphere, and the amount and characteristics of haze may vary depending on the region. In particular, these haze reduce visibility, which can cause air traffic interference and vehicle traffic accidents, and degrade the quality of security CCTVs and so on. Therefore, in the past 10 years, research on haze removal has been actively conducted to reduce damage caused by haze. In this study, local haze removal is performed by weight generation using a haziness degree evaluator to adaptively respond to haze-free, homogeneous haze, and non-homogeneous haze cases. And the proposed method improves the limitations of the existing static haze removal method, which assumes that there is haze in the input image and removes the haze. We also demonstrate the superiority of the proposed method through quantitative and qualitative performance evaluations with benchmark algorithms.

The study on the wake vortex behavior during the aircraft's take-off and landing flight phase is critical to the flight safety of the aircraft, following close behind and the economy of the airport. The study on the wake vortex behavior should include the understanding of the ground effect on the behavior of the multiple wake vortices, generated from aircraft during the take-off and landing flight phase. In thia study, numerical schemes that can consider the ground effect were devised, by applying a vorticity boundary condition and an image method into the existing two-dimensional Fourier-spectral method. The present method was validated by comparing the present results, with the computed and measured data in the published literature. It was shown that the present method can predict the generation and behavior of the secondary vortex near the ground with reasonable accuracy. In future, the effect of the atmospheric conditions such as the stratification and the wind shear on the behavior of the vortex pair will be studied.

In this paper, the style synthesis network is trained to generate style-synthesized video through the style synthesis through training Stylegan and the video synthesis network for video synthesis. In order to improve the point that the gaze or expression does not transfer stably, 3D face restoration technology is applied to control important features such as the pose, gaze, and expression of the head using 3D face information. In addition, by training the discriminators for the dynamics, mouth shape, image, and gaze of the Head2head network, it is possible to create a stable style synthesis video that maintains more probabilities and consistency. Using the FaceForensic dataset and the MetFace dataset, it was confirmed that the performance was increased by converting one video into another video while maintaining the consistent movement of the target face, and generating natural data through video synthesis using 3D face information from the source video's face.

This study aimed to explore fashion technologies for small-scale designer brands and reveal the priorities of the derived fashion technologies. Interviews were conducted with owners of 15 designer brands to explore fashion technologies needed in the field based on the business operation stage (study 1), and an online survey of owners of 61 designer brands was conducted to verify their priorities (study 2). A total of 12 fashion technologies were derived from study 1, including 2 market analysis stages, 6 season planning stages, and 4 product operation stages. In study 2, importance and satisfaction were measured with 12 fashion techniques derived from study 1, and importance-performance analysis (IPA) was performed. The technologies of product management with image tagging and sales channel matching were considered to be the fashion technologies that should be developed first. Second, in the case of maintenance, demand prediction and price determination were applicable. Third, over-effort avoidance was revealed through market analysis and design generation. Finally, in automatic product detail page creation and digital marketing, development was the lowest priority. The results of this study are expected to provide insight into priority areas for fashion technology developers and policy departments providing emerging brand support.
