In order to analyze the feasibility of the drain layer construction method, which is one of the beach protection methods, a hybrid model is constructed by combining the wave model and the seepage flow model. The used wave model is the analytic solution given by Shuto (1972). and the seepage flow model is used by Richards equation which governs the saturated-unsaturated flow in the porous media. It is concluded by the sensitivity analysis of the hybrid model that the most sensitive parameter in the flow field within the beach is the saturated hydraulic conductivity. The developed hybrid model will be efficiently used in the analysis of the parameter when the drain layers are constructed in the beach, if the field datas are obtained more.

In recent years, digital media providing entertainment and information have become an important channel of customer experience. The aim of this study is to evaluate the effects of digital signage's characteristics on flow and brand attitudes and to verify the mediating role of pleasure in digital signage and flow. The stimuli were developed for a sports brand stores using 3D and video editing software. The survey was conducted on 544 subjects from both gender aged 20 to 49 years old, i.e. the population that constitutes the major target group for sports brands. The data collected was analyzed using IBM SPSS 24.0. Specifically, frequency analysis, factor analysis, reliability analysis, t-test, and regression analysis were performed on the data. Based on the results, we can draw the following conclusions; First, the dimension of digital signage was classified into aesthetic and functional attributes. Additionally, we found out that women highly value aesthetic attributes of digital signage while the customers in their 40s pay more attention to functional attributes than their counterparts aged 20-30 years. Second, our results suggest that pleasure has a mediating effect in the relationship between digital signage attributes and flow; specifically, both sub-dimensions of digital signage features (aesthetic attributes and functional attributes) affect flow by means of pleasure. Third, our results demonstrated that the flow of digital signage had a significant impact on brand attitudes.

The present study examined the effect of a methanol extract of Evodiae Fructus on the cardiovascular function in N-nitro-L-arginine methyl ester (NAME)-induced hypertensive Wistar rats after treatment over 6 weeks. In rats treated with NAME, blood pressure, weight of heart, aorta media thickness and media/lumen ratio significantly (p<0.05) increased, whereas coronary flow and heart rate of isolated heart significantly (p<0.05) decreased compared with control group at 6 weeks. In rats treated with NAME and Evodiae Fructus, blood pressure, aorta media/lumen ratio significantly(p<0.05) decreased compared with NAME treated group at 6 weeks. These results suggest that Evodiae Fructus is applicable to the treatment of hypertension and vascular hypertrophy.

The objective of the present study is to investigate the heat storage characteristics of a packed bed according to periodically oscillating flows. Experiments have been performed to measure transient temperature distributions in solid and fluid Phases of the porous media. A simplified analytical model has been developed with intra-particle and dispersion effects neglected, and non-dimensional parameters have been derived. The transient temperature distributions according to the simplified numerical model agree well with the experimental results. Heat storage efficiencies defined in two different ways are obtained for various time periods and face velocities.

Synthesis gas such as hydrogen and carbon monoxide was produced from $CH_4/oxygen$ mixture using insulated pressurized porous media combustor. Experimentally, two cylindrical SiC foams with the different pore density were piled up in a quartz tube and fully premixed mixture was supplied in the axial direction. After stabilizing fuel-rich flame at the interface of the two foams at several pressure conditions, mole fractions of synthesis gases were measured by gas chromatography. Heat recirculation through the inner foam structure could extend the flow velocity of stable region over the laminar burning velocity. As the pressure increased, the rich flammability limit, $H_2/CO$ ratio, and module M increased.

The advent of the "un-tact 2.0 era," described as a "new normal non-face-to-face social relationship," accelerates the transformation of the living paradigm as a fully digital mediated social relationship. The emergence of these new forms of digital behaviors and mediated relationships significantly influences the industry prospect and consumers' individual lives. Advertising has played a decisive role in moving the formation forces of society, creating a dynamic flow of the capitalist system across races and geographical boundaries. Its role will become more fundamental in the physical contactless environment due to the COVID-19 outbreak. Accordingly, advertising has changed and modified its shape and meaning throughout history to adapt to the dynamic external environment. In this article, we illustrated four primary stages of the evolution in the advertising industry from simple advertising to convergence of advertising. Finally, we also identified the challenges of the present advertising industry and the paradigm transformation of "un-tact 2.0" with various related examples.

Korean dramas, commonly referred to as Koreanovelas or K-Dramas in the Philippines, have significantly influenced and reshaped Philippine television culture since the early 2000s. Their impact persists in contemporary television programming, reflecting the transnational flow of media texts across borders. As media content transcends geographical boundaries, local media companies have adopted the practice of producing adaptations of foreign television series for their audiences. This paper examines the adaptation of the Koreanovela The World of the Married into the Philippine series The Broken Marriage Vow, both of which are adaptations derived from the British show Doctor Foster. Through this comparative analysis, I argue that the process of localizing these television shows to suit the preferences of the target audience serves as a tangible manifestation of transnational adaptation. Particularly in an era of globalization, where entertainment is still a thriving enterprise, thus traversing international borders, this phenomenon demonstrates the evolving nature of television content as it adapts and caters to diverse cultural contexts let alone a profitable means to generate an ailing entertainment industry, especially in the time of the pandemic.

Most of the existing interactive arts or entertainment systems consist of the following three steps: 1. the system's prompting the action of the participant, 2. action of the participant, and 3. response of the system. They do not presuppose these successive processes are performed continuously and repeatedly, and they are designed to express the concept of the work in each interaction. The opposite approach is to transmit the concept of the work in a continuous and repeated experience. The authors propose "Adjustive Media" as a type of work based on this approach. Adjustive Media has a spiral model with feedback. When participants experience the work repeatedly, they can recognize the difference of results between each interaction, and they can under- stand more closely the intent of the designer. This paper will propose 3 design processes for Adjustive Media as design method, and will introduce the prototypes of Adjustive Media.

This paper confirmed the roles of images of performance arts, through an analysis of the performance arts realizing media augmented reality, and proceeded audience studies through t-test for verifying the results. As a result, the images used for the performance arts interacted with the audiences through mixing of media, and led to satisfaction for the performance through strong flow and understanding. For some parts, however, an indiscreet use of images caused audiences, who are still familiar with traditional performance arts, to react exclusively toward the media. Eventually, at this time trying new change, convergence media performance arts with images need to orchestrate performance arts and media, so that multiple audiences can easily understand and enjoy, and make an effort to let the audiences get satisfaction based on various experiences. For this, a producer should dedicate to create strategic performance arts contents that can provide professional new knowledge and information, considering even audiences' recognition, as well as their perceptional and psychological characteristics.

This study attempted to grasp the status and perception of Uljin Geumgangsong by grasping mass media issues and user perception using big data, and to present basic data when constructing monitoring using user perception by examining the establishment relationship of agenda setting from a time-series perspective. The results of collecting and analyzing text data that can identify mass media and visitor awareness are as follows. First, both mass media and visitor keywords were related to the importance of the value and meaning of Uljin Geumgangsong. Second, in the case of the connection network, Geumgang Pine Agriculture was centered, but in the case of difference in perception between mass media and visitors, such results were derived due to the object of interest. Third, in the case of the connection relationship structure, the connection strength was strong because there were many overlapping contents of mass media. Fourth, as a result of the centrality analysis, both mass media and visitor-aware keywords were positively recognized as spaces created and maintained through institutional support, and objective perception could be grasped by finding hidden keywords. Fifth, as a result of time series analysis, it was possible to grasp the flow through the issue keywords that appeared by period, and unlike the past, it was recognized as a place for tourism and travel. Finally, as a result of examining whether the agenda setting is consistent, there is a mass media influence, so it is thought that more diverse and more information and publicity are needed by utilizing it.
