Bromate is a disinfection by-product generated mainly from the oxidation of bromide during the ozonation and disinfection process in order to remove pathogenic microorganism of drinking water, and classified as a possible human carcinogen by International Agency for Research of Cancer (IARC) and World Health Organization (WHO). For the purpose of determining the trace level concentration of bromate, several sensitive techniques are applied mostly based on suppressed conductivity detection and UV/Visible detection after postcolumn reaction (PCR). In this study, the suppressed conductivity detection method and the PCR-UV/Visible detection method through the triiodide reaction were compared to analyze the trace bromate in water samples and estimated for the availability of these analytical methods. In addtion, the state-of-the-art techniques was applied for the determination of trace level bromate in various water matrices, i.e., soft drinking water, hard drinking water, mineral water, swimming pool water, and raw water. In comparison of two analytical methods, it was found that the conductivity detection had the suitable advantage to simultaneously analyze bromate and inorganic anions, however, the bromate might not be precisely quantified due to the matrix effect especially by chloride ion. On the other hand, the trace bromate was analyzed effectively by the method of PCR-UV/Visible detection through triiodide reaction to satisfactorily minimize the matrix interference of chloride ion in various water samples, showing the good linearity and reproducibility. Furthermore, the method detection limit (MDL) and recovery were 0.161 ㎍/L and 101.0-108.1 %, respectively, with a better availability compared to conductivity detection.

This study first examined the social meanings of typicality found in the prison, (solitary) confinement, and conduit(passage) in Peter Halley's works, in which both the prison and (solitary) confinement represent a suppressed structural framework. The former has freedom and escape excluded from it, and the latter allows for mutual regulation and connection as a space of positive mediation. Conduits are interpreted to be flexible and have the potential of creating something new through connection and communication with the outside world. The study then compared and analyzed the meanings of typicality in Halley's works and the concept of segments proposed by Gilles Deleuze and Félix Guattari as social justice in that both of them were in the same context. The findings lead to a conclusion that Halley's prison, (solitary) confinement, and conduit(passage) can be connected to a solid, flexible, and escape segment, respectively, by Deleuze and Guattari.

Since the radar satellite missions such as TerraSAR-X and COSMO-SkyMed were launched in 2007, the spatial resolution of spaceborne SAR(Synthetic Aperture Radar) images reaches about 1 meter at spotlight mode. In 2011, the first Korean SAR satellite, KOMPSAT-5, will be launched, operating at X-band with the highest spatial resolution of 1 m as well. The improved spatial resolution of state-of-the-art SAR sensor suggests expanding InSAR(Interferometric SAR) analysis in urban monitoring. By the way, the shadow and layover phenomena are more prominent in urban areas due to building structure because of inherent side-looking geometry of SAR system. Up to date the most conventional algorithms do not consider the return signals at the frontage of building during InSAR phase and SAR intensity simulation. In this study the new algorithm introducing multi-scattering in layover region is proposed for phase and intensity simulation, which is utilized a precise LIDAR DSM(Digital Surface Model) in urban areas. The InSAR phases simulated by the proposed method are compared with TerraSAR-X spotlight data. As a result, both InSAR phases are well matched, even in layover areas. This study will be applied to urban monitoring using high resolution SAR data, in terms of change detection and displacement monitoring at the scale of building unit.

This paper determined students' ranks of difficulty on the use of materials in terms of 1) understanding the layout of the learning materials, 2) reading comprehension of the learning materials, and 3) realization on relevance to needs of the learning materials. It also determined students' 4) rank and frequency of attitude on the materials. With the data gathered through 128 survey questionnaires, 7 focused group discussions, and 10 interviews, the results were found out that there was an inappropriate assessment procedure set by this particular university. The researcher concludes that: 1) design of four types of classes by just using the two textbooks with their respective workbooks is grammar-based with limited conversation activities; 2) placement for these students in one big class size was implemented without considering their common interest and motivation and language levels; and, 3) qualification of teachers teaching these EFL students did not support students' real needs and the language program itself. Content professors who were made to teach may have the ability to input learning, but their teaching styles may differ from the ones who are real English teachers. This paper then recommends that teachers and school administration should have an appropriate placement exam before students attend the class, especially in a big class size. There could only be a few problems among students in one big class size when students' level of competence is proportioned. With this, topics and conversation activities can even be more flexible with the maneuver of art of questioning, various dimensions of thinking, strategic competence, learning attitude or behavior, etc. to ensure sustenance of communicative mode and level of interest and motivation in the classroom. Grammar-based instruction can only be taught when a need arises. Thus, the course description of each class will be able to transact the objectives ready for developing students' communication competence. Moreover, proper measurement can be utilized to validly assess the amount of students' learning and the progress of language curriculum design in terms of materials selection and teaching approach.

North Korean youth is a youth aged 6 to 18 who lives in a South Korean society after having left North Korea. In this study, photo-in-education (PIE) provides North Korean youths with opportunities for cultural and arts education, and to help them adjust themselves to South Korean society. As a result, they, as young people who are exploring a new life in South Korea, have been able to express their own inner world through photos, videos, and writings. Also, young people have developed a bright and clear mind, and enhanced an expressive power and logical power that helps grow healthily and intelligently. Further, it is the aim of this education to help them to have a positive feeling for society and to do their best to become a healthy member of society, who will be able to contribute to society. Through PIE, it was found that North Korean defectors were able to see themselves positively and express their own inner self positively, despite that they are still in the negative and shady side of life.

This thesis explores the place and role of a performer's action from a perspective of a director and playwright David Mamet's concept for performer training. This thesis takes inspiration from the idea of Mamet's simple and practical investigation specifically in text-based approach with a performer's bodily function on stage. For Mamet, the writings and practices of many different body-centered training are not rooted in the principle and nature of acting/performance. Reconsidering complicated approaches particularly psychological-oriented theory, practice, and assumption draw on several practitioners takes us beyond the field of visible and/or outer appearance of a performer which in turn leads the performer's body to be as abstract therefore not to being in the moment on stage. Arming the points, we argue that whatever disciplines and/or methods necessarily need to meet the principles and demands of acting/performance/theatre to connect to the materials, an action/objective given by a specific playwright which the performer must inhabit through his/her body. Out of the context, any 'method' serves no purpose. That is, the mechanics of an action is an extension of addressing what a performer's specific needs which shifts his/her body to respond appropriately to the theatrical demands. Taking this argument further, we claim that the purpose of performer training should not be understood as learning and improving techniques or skills for his/her self-perfection. The research finding shows that this resembles to the phenomenon that the visible very often precedes the invisible where the performer's body lose a clarity with no more chance to happen and/or change the event(s). Rather, it is a process of learning what/how to learn which in turn brings us back to the central question of why we do training for what purpose in this contemporary era. Exploring and answering these questions is not only a way to employ the key materials applicable to the theatrical demands but also to achieve the identify as a professional performer/doer on stage.

Development of 5th generation mobile telecommunication technology is visualizing ideal hyper-connected social information and communication technology (ICT). In particular, virtual reality (VR) technology is at the starting point for new expansion and leaps. This work defines virtual reality as media in this context and collects and analyzes discourse on its scalability around space and communication theory. We first elaborated the concept, starting with the early discussions of the virtual reality concept in 1990, and discussed the relationship between the physical world and digital information, expression and interaction immersion as a medium, simulation, art creation theory, and finally evolutionary development. In conclusion, beyond the discourse on the technology of virtual reality, academic subjects were required to have theoretical frameworks on cognitive science, neuroscience, social science, and humanities issues (ethics, personality, etc.) for the development and evolution of virtual reality. In other words, it is time for the evolution of virtual reality to be discussed, which can be moved beyond.

Since the era of industrial revolution, the waste volume has continued to grow; waste management has thus become one of the major global environmental challenges facing humanities today. Waste treatment and management issues trigger NIMBY movements, and disputes among states, governments, and social actors over the issues have been accelrating. At the level of states and sub-states, various measures including institutions, laws, regulations, market-oriented methods, consensus and collaborative governance have been introduced to address various problems associated with waste. More recently, science and technology has been applied to the waste treatment and management under the notion of circular economy. However, societal support for addressing waste problems still remains inadequate, calling for new approaches and alternative pathways. In this context, this study examines two cases of urban incineration plants designed by Hudertwasser, Austria-born artist and architect: Spittelau, Austria, and Osaka, Japan. Through these case studies, I demonstrate how creative and innovative culture-technology convergence can shed new light on challenging environmental issues such as an urban waste problem.
