This study examined the Japanese and Chinese journalist's views on anti-Korean wave, who are the public and authoritative discourse producers in Japan and China, respectively. In so doing, the study aims to understand the ways in which the phenomena of anti-Korean wave take place and are diffused. According to the findings, anti-Korean wave in north-east Asia is affected by anti-Korea sentiments that have been induced from historical and political relations as well as cultural conflicts. In specific, the anti-Korea sentiments found in both Japan and China are geopolitical particularity and historical relations function to frame their cultural receptions of Korean pop culture. In other words, the phenomena of anti-Korean wave in both countries do not stem directly from local audiences' either discontents or apathy on Korean pop contents. However, while Japanese anti-Korean wave seems to be mere expressions of anti-Korea sentiments, Chinese sentiments of anti-Korean wave are triggered and transferred by, or articulated with their anti-Korea sentiments.

Accurate simulation of free-surface wave flows around a ship is very important for better hull-form design. In this paper, a computational fluid dynamics (CFD) code which is based on the open source libraries, OpenFOAM, was developed to predict the wave patterns around a ship. Additional anti-diffusion source term for minimizing a numerical diffusion, which was caused by convection differencing scheme, was considered in the volume-fraction transport equation. The influence of the anti-diffusion source term was tested by applying it to free-surface wave flow around the Wigley and KCS model ships. In results, the wave patterns and hull wave profiles of the Wigley and KCS model ships for various anti-diffusion coefficients showed quite close patterns. While, the band width of the water volume-fraction values between 0.1 to 0.9 at the Wigley and KCS model hull surfaces was narrowed by considering the anti-diffusion term. From the results, anti-diffusion source term decreased free-surface smearing.

Despite the enormous success in Japan of Korean popular culture, including TV dramas and K-pop, over the past few decades, anti-Korean sentiment in the country has become increasingly visible and intense. In this article, we examine how young Japanese female fans of Korean popular culture engage with the Korean Wave discourse while also engaging with―or, rather, disengaging from―anti-Korean movements and hate speech. Whereas previous scholarship on the Korean Wave has emphasized the power of active fans' agency, this paper investigates how the fans who passionately and self-reflexively consume Korean popular culture understand and react to the growing anti-Korean sentiment in Japan. Through in-depth interviews with 15 of these fans in their 20s and 30s, we show how they have navigated the discursive space between appreciation for Korean culture and anti-Koreanism in Japan.

This paper aims to investigate the cultural conflicts and characteristics of anti-Korean Wave discourse taken placed among Southeast Asian countries. To do this, it takes Vietnam and Indonesia as the study cases, which have been showing a trend of anti-Korean Wave discourse as well as high popularity of Hallyu. As research methods, the paper analyzes both on-line discourses of anti-Korean Wave and the email audience interviews from both countries. The results show some significant differences between the two countries as well as the similarity that Anti-Korean Wave discourses have been actively produced and disseminated through on-line media. As for Indonesia, the Anti-Korean Wave discourse pivots on the elements clashing between Indonesia's religion and cultural values and Korean consuming culture. According to the Anti-Korean Wave discourse, K-pop contents and entertainers are criticized for damaging the society's morals and cultural identities based on Islamic rules and values. Thus, the sentiment of the Anti-Korean Wave is likely to lead to the cultural nationalism for the sake of their cultural identity. As for Vietnam, anti-Korean Wave discourse mainly consists of issues on enthusiastic K-pop fans' anti-social behaviors and generational conflicts which are presumed attributed as the chief factor of the Anti-Korean Wave. In the Vietnamese discourse, social elites and adults treat the enthusiastic K-pop fans as those who are in need of educational care or psychological therapy. Unlike the Indonesian case, anti-Korean Wave discourse in Vietnam criticized the K-pop and the performer's competence for being cheap sexy and incompetence. They also denounce Korean dramas for their trite, typical story lines, use of excessive emotion, and unrealistic nature. However, the two country's interview participants have in common both acknowledged that rather than considering the Anti-Korean Wave as an issue that needs to be resolved it should be embraced as a natural cultural phenomenon.

This paper describes a theoretical model and acoustic analysis of hysteresis of contacting surfaces subject to compression pressure. Contacting surfaces known to be nonlinear and hysteretic is considered as a simple spring that has a complex stiffness connecting discontinuous displacements between two solid contact boundaries. Mathematical formulation for 1-D interfacial wave propagation between two contacting solids is developed using the complex spring model to derive the dispersion relation between the interface wave speed and the complex interfacial stiffness. Existence of the interface wave propagating along the hysteretic interface is studied in theory and discussed by investigating the solution to the dispersion equation. Unlike the linear interface without hysteresis, there can exist only one distinct mode of interface waves for the hysteretic interface, which is anti-symmetric motion. The anti-symmetric mode of interface wave propagates with the velocity faster than the Rayleigh surface wave but less than the shear wave depending on the interfacial stiffness. If the contacting surfaces are compressed so much that the linear interfacial stiffness is very high, the hysteretic stiffness does not affect the interface wave velocity. However, it has an effect on the speed of interface wave for a loosely contact surfaces with a relatively low linear stiffness. It is also found that the phase velocity of anti-symmetric wave mode converges to the shear wave velocity in despite of the linear stiffness value if the hysteretic stiffness approaches 0.5.

To understand the physical method for induction of anti-bacterial substances from the silkworm larvae, Bombyx mori, three physical methods, i.e., infrared radiation, ultraviolet radiation and ultrasonic wave, have been used in this study. The results have shown that ultrasonic wave can induce anti-bacterial sub-stances effectively than radiations in the B. mori larva. The induction of anti-bacterial substances was different from silkworm race to race. Summer-autumn silkworm race (Qiufeng${\times}$Baiyu) was easy to induce antibacterial substances. It is suggested that the ultrasonic wave is a simple and easy method for induction.

The predominant concern of the study consist of: (1) the effect of young Chinese's consuming of Korean cultural wave contents including Korean TV drama, film, and K-pop on their anti-Korean sentiment; (2) the second-order mediating effects of both liking for Korean wave and positive perceptions of Koreans. The research is based on a survey conducted with 695 chinese people between high-teen and 20's, located in eleven cities of seven provinces. The notable findings are as follow: First, the higher consuming of Korean cultural wave contents, the higher anti-Korean sentiment. Second, young Chinese, consuming more Korean cultural contents, show more liking for Korean wave. The more favor of Korean cultural contents, the more positive perceptions of Koreans. The more liking for Koreans wave contests and the more positive perception of Koreans, the less anti-Korean sentiment. Therefore, it is proved that liking for Korean cultural wave contents and perceiving Koreans with a positive view are important mediator to reduce the anti-Korean sentiment. Some practical implications are discussed based on this study's findings above.

There are many difficulties to supply constant power to marine facilities which operate in the sea. Especially, there is a limit to stand alone power supply systems due to the influence of weather conditions. That's why a hybrid power supply system is required to overcome these problems. This paper will describe an Electronic Anti-Fouling System (EAFS) to maximise the power efficiency for a solar - wave hybrid power generation system. A main factor reducing the efficiency of a Wave Energy Converter (WEC) is due to the attachment of aquatic life forms. Therefore the aim of this research is to develop a simulation programme to enable the design of more efficient EAFS for hybrid power generation systems and to provide valuable data for production of more efficient EAFS.

Accurate simulation of free-surface wave flows around a ship is very important for better hull-form design. In this paper, a computational fluid dynamics (CFD) code, termed SNUFOAM, which is based on the open source libraries, OpenFOAM, was developed to predict the wave patterns around a ship. Additional anti-diffusion source term for minimizing a numerical diffusion, which was caused by convection differencing scheme, was considered in the volume-fraction transport equation. The influence of the anti-diffusion source term was tested by applying it to free-surface wave flow around the Wigley model ship. In results, the band width of the volume fraction contours between 0.1 to 0.9 at the hull surface was narrowed by considering the anti-diffusion term.

The Mobile Harbor(MH) is a new transportation platform that can load and unload containers to and from very large container ships in the sea. This loading and unloading by crane can be performed with only very small movements of the MH in waves because MH is operated outside of the harbor. For this reason, an anti-rolling tank(ART) and an active mass driving system(AMD) were designed to reduce MH's roll motion, especially at the natural frequency of MH. In the conceptual design stage, it is difficult to confirm the design result of theses anti-rolling devices without modeling and simulation tools. Therefore, the coupled MH and anti-rolling devices' dynamic equations in waves were derived and a simulation program that can analyze the roll reduction performance in various conditions, such as sea state, wave direction, and so on, was developed. The coupled equations are constructed as an eight degrees of freedom (DOF) motion that consists of MH's six DOF dynamics and the ART's and AMD's control variables. In order to conveniently include the ART's and AMD's control dynamics in the time domain, MH's radiated wave force was described by an impulse response function derived by the damping coefficient obtained in the frequency domain, and wave exciting forces such as Froude-Krylov force and diffraction force and nonlinear buoyancy were calculated at every simulation time interval. Finally, the roll reduction performances of the designed anti-rolling devices were successfully assessed in the various loading and wave conditions by using a developed simulation program.
