This edited volume assesses the quality of democracy in the Republic of Korea three decades after its formal democratization in 1987. It has been argued that Korea's two subsequent power turnovers prove that its democracy has been successfully consolidated, despite its tremendous progress; however, recent developments show signs of deterioration and retreat. Therefore, drawing on the recent quality of democracy literature this volume sets out to answer the question: Where does Korea's democratic quality stand today? The three chapters in first section of the book focus on aspects related to the presidency, political parties, and organized labor, also including the perspective of governance and human security as well as on the rule of law regarding the role and function of the prosecution. This is followed by a set of four chapters in section two that address the dimensions of democratic quality such as participation, freedom, equality, and responsiveness. The final, third section includes contributions on related inter-Korean policy issues. This book is an invaluable resource for political and social scientist working on democratic quality, and at the same for scholars in Asian or Korean Studies at faculty level as well as on graduate student level.

This monograph is a comprehensive introduction to the field of soccer robotics. Soccer robotics has become an important research area integrating mechatronics, computer science and artificial intelligence techniques to create real-world autonomous systems. It also serves as a popular test arena in which to compare the different approaches, in diverse types of competition and with varying levels of distributed perception and collaboration. The focus of this monograph is the FIRA framework of Soccer Robotics, in particular MiroSot, which uses a central overhead camera to overview the whole soccer field and a central control of the robots. "Soccer Robotics" completely describes the different requirements to create a soccer team and details the hardware aspects, the computer vision needed, navigation, action selection, basic skills and game strategy. These aspects are described at an undergraduate level, resulting in a book not only useful as a text for courses but also indispensable for everyone who wants to participate in MiroSot robotics.

Extensive study of solar energy is increasing as fast as the threat of global warming is getting serious. Solar energy is considered the best source of renewable energy because it is clean and unlimited. Solar radiation can be harnessed and converted into different forms of energy that does not pollute the environment. In order to transform solar radiation, we need collectors of sunlight, such as solar cells. The main challenges are energy security, the increasing prices of carbon-based energy sources, and global warming. We cannot use sunlight during the night, so an energy storage system (ESS) is necessary. The best ESS is one with high power and high energy density. This book introduces the basic concepts of an ESS. Written by Prof. Hee-Je Kim, who leads an interdisciplinary team at the Pusan National University, this book compiles and details the cutting-edge research that is revolutionizing solar energy by improving its efficiency and storage techniques through the development of engineered sunlight. It discusses the fabrication and commercialization of next-generation solar cells such as dye-synthesized, quantum-dot, and perovskite solar cells, besides describing the high-energy and power-density-flexible supercapacitor for a hybrid ESS, as well as the dual active bridge (DAB), DC/DC converter, MPPT, PV inverter, and remote control by a smartphone with a novel algorithm for a power-conditioning system.

Learn about the latest advances in high-brightness X-ray physics and technology with this authoritative text. Drawing upon the most recent theoretical developments, pre-eminent leaders in the field guide readers through the fundamental principles and techniques of high-brightness X-ray generation from both synchrotron and free-electron laser sources. A wide range of topics is covered, including high-brightness synchrotron radiation from undulators, self-amplified spontaneous emission, seeded high-gain amplifiers with harmonic generation, ultra-short pulses, tapering for higher power, free-electron laser oscillators, and X-ray oscillator and amplifier configuration. Novel mathematical approaches and numerous figures accompanied by intuitive explanations enable easy understanding of key concepts, whilst practical considerations of performance-improving techniques and discussion of recent experimental results provide the tools and knowledge needed to address current research problems in the field. This is a comprehensive resource for graduate students, researchers and practitioners who design, manage or use X-ray facilities.

Depending on in-plane size, the application of Josephson junctions varied from the terahertz (THz) oscillator to the single electron transistors. This book is focused on the study of submicron Josephson junctions fabricated in high-temperature superconductors (HTS). The unit cell of layered HTS show intrinsic Josephson junctions (IJJs) phenomenon. The Cooper pair tunneling in the IJJs can be affected by quantum phase fluctuations when the resistance of a submicron stack is in the range of quantum resistance. To observe this quantum effect, stacks of IJJs of various in-plane area down to submicron range have fabricated in Bi-2212 single crystal whiskers using three-dimensional focused ion beam etching technique. Submicron stacks show a strong suppression in critical current density. The possible mechanisms for this suppression are discussed and the data analysis points to the quantum phase fluctuations as the most likely mechanism of this effect. Furthermore submicron stacks of a-axis oriented multi layered thin film of YBa2Cu3O7 and PrBa2Cu3O7 (Y123/Pr123) Josephson junctions are studied in presence of external microwave irradiation.

Many automatic schema matching approaches have been proposed, but the challenge is still daunting because of the complexity of schemas and immaturity of technologies in semantic representation, measuring, and reasoning.The book focuses on three challenging problems in schema matching. First, the existing approaches have often failed to sufficiently investigate and utilize semantic information imbedded in the hierarchical structure of the XML schemas. Secondly, due to synonyms and polysemies found in natural languages, the meaning of a data node in the schema cannot be determined solely by the words in its label. Thirdly, it is difficult to correctly identify the best set of matching pairs for all data nodes between two schemas.A variety of computer experiments have been conducted with encouraging results that show the proposed approaches in this book are valuable for addressing difficulties in XML schema matching.
