BPS Electromagnetic Waves on Giant Gravitons
We find new 1/8-BPS giant graviton solutions in , carrying
three angular momenta along , and investigate their properties.
Especially, we show that nonzero worldvolume gauge fields are admitted
preserving supersymmetry. These gauge field modes can be viewed as
electromagnetic waves along the compact D3 brane, whose Poynting vector
contributes to the BPS angular momenta. We also analyze the (nearly-)spherical
giant gravitons with worldvolume gauge fields in detail. Expressing the
in Hopf fibration ( fibred over ), the wave propagates along the
fiber.Comment: 25 pages, no figures, v2: references adde

Although these talbungmin receive South Korean citizenship, resettlement education, and financial assistance almost immediately upon their arrival, a large number of them continue to face severe difficulties due to their cultural and linguistic differences in contemporary South Korean society. At the same time, the South Korean cinema industry continues to release division films of various genres, garnering national and international attention for its Hollywood style action and unique backdrop of the divided Korean peninsula. How can these films allow us to understand the discrimination and challenges that North Korean defectors experience? What messages do South Korean division films deliver about North Koreans, and how do they portray the perspectives of South Koreans?
This study endeavors to combine the two different research fields of North Korean resettlement and South Korean cinema studies to understand the discrimination that North Korean defectors experience in South Korean society. Film and media studies is an effective method to examine how South Koreans negative perceptions of North Koreans have been constructed: above any other platform, films serve as a metaphysical, audiovisual tool that delivers the human perspective in the most similar way to reality. Therefore, this study will examine how South Korean films have depicted North Korean characters, shedding light on the various prejudices and stereotypes that have been projected upon North Koreans on screen. Through comparing and analyzing 20 films produced by South Korean filmmakers, this study aims to highlight the ways in which cinematic representations of North Koreans reflect the conceptualization of North Korean defectors in South Korean society.
Chapter I demonstrates how this study will combine the two frameworks of film theory and qualitative research, unlike previous works, and Chapter II provides a historical overview of the division films along with major political changes among inter-Korean relations. This overview provides background context on the evolution of division films in South Korean cinematic history, separating each time period by their respective administration and political party. Chapter III gives an analysis of the North Korean characters in each division film, comparing their similarities and differences according to each genre. The chapter is divided into different categories of the division film, including espionage films, war films, and documentary films about North Korean defectors. With the collected analyses, Chapter IV describes interviews with North Korean defectors to examine the gap between South Korean and North Korean perceptions of North Koreans. The interview results provide an evaluation of the accuracy of North Korean characters in South Korean division films. Finally, Chapter V summarizes the various stereotypes and frameworks that South Korean filmmakers have used over the past decades, and explore what new efforts could be made in the future to create a more complex and nuanced North Korean character. Combining the interview results with the analysis of North Korean characters in South Korean division films, this chapter will propose ways forward for South Korean division films to present North Korean characters. Through these suggestions, this study aims to positively alter the perceptions of South Korean society towards North Korean defectors and contribute to the sociocultural integration of North and South Koreans.Chapter I.

Breaking Down the Codes: A Study of the Nonverbal Emblems and Regulators Used in International B-Boy Competitions
This study explored the use of nonverbal emblems and regulators in international b-boy competitions. Using semiotics, a lexicon of the emblems and regulators was recorded. Then the dimensions from a theory of semantics of dance were applied to understand how b-boy crews (dance teams) from around the world use gesture to communicate with the audience, judges, and other crews. The study analyzed how culture influences the use of emblems and regulators in the intercultural exchange that occurs during the international b-boy competitions, such as Battle of the Year (BOTY) and R16 World Series. Four videos from the 2013 and 2014 BOTY and 2015 R16 were analyzed. The study concluded that cultural dimensions such as collectivism and indulgence influences emblem selection, intensity, and frequency. These nonverbal elements exhibit an overall impact on the battle and the determination of the winner.

Previous studies on the power elite in North Korea have focused mainly on analyzing the origins and backgrounds of individual power elites or their connection with Suryeong. This thesis interprets the analysis and data on the North Korean power elite achieved by these previous studies from the perspective of autocratic theory. The autocratic theory is useful because it distinguishes between groups of acts that form a dictatorship and reveals the operating principles of dictatorship through changes in their relationships. In particular, the Selectorate Theory of Bueno de Mesquita (BdM) explains the relationship between the ruler and the Winning Coalition through the size of the Selectorate and the Winning Coalition, which is the basis of the theoretical discussion in this thesis.
Kim Jong-un diminishes the size of power elites in an effort to consolidate the dictatorβs political standing. And he staves off factional coalitions from forming by stirring up organizational structure and frequent cabinet/elite reshuffle. These two strategies are accompanied by an institutional change in the βnormalizationβ of the Party-Sate System. This thesis analyzes the partyβs empowerment in North Korea from the perspective of Kim Jong-unβs strategy of maintaining his dictatorship.Chapter 1. Introduction 1

Vector chiral states in low-dimensional quantum spin systems
A class of exact spin ground states with nonzero averages of vector spin
chirality, , is presented. It is
obtained by applying non-uniform O(2) rotations of spin operators in the XY
plane on the SU(2)-invariant Affleck-Kennedy-Lieb-Tasaki (AKLT) states and
their parent Hamiltonians. Excitation energies of the new ground states are
studied with the use of single-mode approximation in one dimension for S=1. The
excitation gap remains robust. Construction of chiral AKLT states is shown to
be possible in higher dimensions. We also present a general idea to produce
vector chirality-condensed ground states as non-uniform O(2) rotations of the
non-chiral parent states. Dzyaloshinskii-Moriya interaction is shown to imply
non-zero spin chirality.Comment: 4 pages, 1 figur
Cosmic Inflation from Emergent Spacetime Picture
We argue that the emergent spacetime picture admits a background-independent
formulation of cosmic inflation. The inflation in this picture corresponds to
the dynamical emergence of spacetime while the conventional inflation is simply
an (exponential) expansion of a preexisting spacetime owing to the vacuum
energy carried by an inflaton field. We show that the cosmic inflation arises
as a time-dependent solution of the matrix quantum mechanics describing the
dynamical process of Planck energy condensate in vacuum without introducing any
inflaton field as well as an {\it ad hoc} inflation potential. Thus the
emergent spacetime picture realizes a background-independent description of the
inflationary universe which has a sufficiently elegant and explanatory power to
defend the integrity of physics against the multiverse hypothesis.Comment: 6 pages, 1 figure; Contribution to the Proceedings of the Second
