Through the evolutionary process of the North Korean defector support policies, this research investigates the background behind the formation of non-profit organizations for the North Korean defectors and to identify and understand the problem through their characteristics and functions. Starting from 1990, with an increase in the North Korean Defectors' population as well as the introduction of multicultural society, various environmental factors, such as the domestic socio-environmental changes, resulted an increase in number of private organizations. However, not to mention the size and functions of the organizations, some do not even have required legal organizational structures in place. Their business activities, in some cases, are irrelevant to the original purpose and objectives. Moreover, the fact that 83% of the North Korean Defectors Organizations are based in Seoul while 25.5% of the North Korean Defector residing in Seoul, inevitably make the reputation of the organizations to be illegal and dishonest due to the excessive level of competitions among the similar types of organizations. In reality, the organizations show lack of growth in the areas such as securing necessary employments to the Defectors or providing educations to the youth, who will eventually become the future leaders, in building the awareness capacity toward the unification. These results show that, in conducting their activities, the organizations must be aware of the rights and responsibilities as the constituents of the society, plus the government's practical efforts in improving these issues are also necessary.

The modern society is changing paradigm by the 4th industrial revolution. In these changes, the importance of geospatial information leading to the fusion and connection of persons and objects is increasing day by day. GNSS CORS(Continuously Operating Reference Station) plays a pivotal role in the geospatial information by providing basic data for surveying control points, mapping, navigation, geophysical research, and so on. On the other hand, the satellite surveying technologies are developing rapidly and it is necessary to investigate the status of the satellite surveying environment and search for future directions. In this study, the environment related to satellite survey by operation status of domestic and overseas CORS(Continuously Operating Reference Station) was tried to analyze. Through the research, The operation status of NGII and IGS CORS were presented. It was found that the availability ratio of multiple satellites to the CORS of NGII are lower than that of IGS CORS. Considering the improvement of positioning performance by using multiple GNSS, it is necessary to use multi-satellites in the future.

Electronics cultural atlas is a typical methodology for the Digital Humanities. Since electronic cultural atlas could visualize various cultural information based on electronic atlas, that is an information visualization, users are able to make intuitive understanding on specific areas. Therefore, it can be effectively utilized in Area Studies and also helps users to understand comprehensively information on historic event in particular area with time information, because electronic cultural atlas represents a particular subject and time information with geographical information based on map. In other words, electronic cultural atlas may be considered as a specialized system of Digital Humanities for studying the Humanities and Area Studies. In this paper, we design and implement mediterranean electronic cultural atlas(MECA) for researchers of the Mediterranean area that has cultural hybridity formed the exchange of various aspects such as civilization, religion, race and language. In detail, a 'Digital Humanities Research Support System' is constructed to visualize research outcomes related to the Mediterranean area on Electronic Cultural Atlas and to use for researches.

This thesis investigates the cultural meanings of the first optical instrument, Camera obscura, in the pre-modern age, while it explains the development as well as the use of the Camera obscura in Europe and Korea. For this purpose the thesis traces the significant phases of the historical developments of the Camera obscura from L. da Vinci, G. B. della Porta, D. Barbaro, A. Kircher to J. Zahn etc. The Camera obscura was not only the symbolic instrument of the modernism in the sense that human being wanted to observe the outer world by himself and to be freed from the viewpoint of the christianity, but also was the forerunner of the modern visual culture, because it first time reproduced the artificial image of the natural world. Since the second half of the 17th century the box-type reflex Camera obscura had been produced, it began to be used as aid to drawing for painters like J. Vermeer, A. Canaletto and J. Reynolds etc. throughout Europe. It tells the evidence of the close relation between art and technology in the pre-modern age. Around the end of the 18th century the Camera obscura was brought to Korea, the closed country of the Fareast, by the scholars of the so-called 'Realist school' (Silhak-pa) who went to Beijing to acquire knowledges on the Western science from the European priests. In 1780s Yak-yong JUNG, one of the representative scholars of the Realist school, experimented the Camera obscura, and then, it was used for sketches of higher aristocrats' portraits by the supreme portrait painter of that time, Myoung-ki LEE. Those were possible only under the reign of the culturally liberal and reformative King, Jung-jo (ruled 1776-1800), and after his retreatment the inquiry of the Camera obscura had been dimished. It is not a historical coincidence that the Camera obscura could be examined and used in the period of the Enlightment both in Europe and Korea.

X-ray absorption fine structure (XAFS) analysis using X-ray absorption spectroscopy is being applied as a state-of-the-art method in a wide range of disciplines. This review article summarizes the overall procedure of XAFS analysis from the preparation of soil samples to the analysis of data in X-ray absorption near edge structure (XANES) region and extended Xray absorption fine structure (EXAFS) region. The previous studies on application of XANES and EXAFS techniques in environmental soil science field are discussed and classified them according to metal(loid)s (As, Cd, Cu, Ni, Pb, and Zn). A significant number of previous studies of XAFS application in the environmental soil science field have focused on the identification of Pb chemical species in soil. Moreover, XANES and EXAFS techniques have been widely used to investigate the contamination source via identification of metal species. Similarly, these techniques were applied to identify the mechanisms of metal stabilization in soil after application of various amendments, phytoremediation, etc.

We herein present the design and fabrication of a Rx core chip operating in the X-band (10.5~13 GHz) using Win's commercial $0.25-{\mu}m$ GaAs pHEMT process technology. The X-band core chip comprises a low-noise amplifier, a four-bit phase shifter, and a serial-to-parallel data converter. The size is $1.75mm{\times}1.75mm$, which is the state-of-the-art size. The gain and noise figure are more than 10 dB but less than 2 dB, and both the input and output return losses are less than 10 dB. The RMS phase error is less than $5^{\circ}$, and the P1dB is 2 dBm at 12.5 GHz, the performance of which is equivalent to other GaAs core chips. The fabricated core chip was packaged in a QFN package type with a size of $3mm{\times}3mm$ for the convenience of assembly. We confirmed that the performance of the packaged core chip was almost the same as that of the chip itself.

This paper presents MIDAS (Media Interaction Design Authoring System), an authoring toolkit for designers and artists to develop working prototypes in new interaction design projects. Field research were conducted to identify the requirements and a case study of designing new interactive products was carried out to examine the feasibility of the new tool. MIDAS provides easier ways of integrating hardware and software, to manage a wide range of electric input and output elements and to employ 3D Augmented Reality technology within conventional multimedia authoring tools, such as Director and Flash, which are popularly used by designers. MIDAS was used in case study projects of design education as well as by voluntary designers for evaluation. From the result of case studies, it was found that many design projects were successfully accomplished using MIDAS. Designers who participated in the projects reported that MIDAS not only helped them to concentrate more on ideation but also was very easy to use as they implemented the physical interface concepts without advanced engineering skills. It is expected that MIDAS can also support prototyping in interactive media an, tangible user interface development and related human computer interaction fields.

This study investigates how 'multi-perspective' can be utilized in animation. For this goal, 1 used the traditional techniques of Korean folk paintings called 'Minhwa.' Most 'Minhwa' works, employ 'multi-perspectives', instead of linear perspective of the Western tradition that has been only taught to students under the formal education system. In Minhwa parts of reality are not only stylized but also fragmented and combined within the same frame. Other common techniques of 'Minhwa' include frontal view, bird's eye view, and inverse-perspective, which are of ien combined in one single work. The purpose of this study is to develop a working principle and practically apply it to , an animation piece based on the Korean folktale of the same title. In doing so, I have proposed a way to reconstruct and revitalize the traditional art form in the age of digital technology and have concluded that 'Multi-perspective' in 'Minhwa' can be utilized in other contents such as animation.'Multi-perspective' in 'Minhwa' is a rich source that has numerous cultural applications.

With the introduction and expansion of 'maker movement', maker culture captured attention and saw itself as an emerging culture. This study aims to analyze published books, policy report, columns and news articles related to maker culture through the perspective of critical discourse analysis. Maker movement led by the government gives meaning to the maker culture as the force of 'creative economy' that can overcome the economic crisis. Following this meaning making, one-man digital fabrication start-ups have been actively promoted by government policies. In the case of Seoul, it criticizes government led maker movement that only focuses on economy and institutionalizes maker movement by focusing on the maker culture's aspect as 'digital social innovation' that can resolve social problems. In the world of art, it tries to rediscover the value craft, that is, 'creative craftsman'. Moreover, resistance movement that tries to fight against dominant technology structure through constructing 'critical making' was also spotted. Nonetheless, it is rather untimely to definitely find dominant discourse's power effect in reality and sign of rupture in dominant structure as the result of resisting discourse's struggle. Thus, maker movement is the field of struggle where an ongoing clash can be found: between discourse strategy that tries to make maker culture a social or economic asset by combining with dominant power structure, and alternating or resisting practice of signification that focuses on its cultural techno-political potential.
