최근 들어 한국 주류의 대중음악 시장은 대형 기획사의 기획형 음악으로 획일화되고 있는 현상이 증가하고 있다. 대중음악의 장르가 편중되는 현상이 나타나면서, 그중 다양성에 대한 대안으로 인디음악이 주목되고 있다. 그러나 최근 인디음악 역시 문화의 획일화 현상을 닮아가고 있다는 의견이 지배적이다. 급변하는 시대의 흐름 속에 인디음악의 상업적 변화에 대한 원인을 분석하고, 인디음악이 나아가야 할 방향에 대하여 고찰한다. 이에 본 연구는 인디음악의 본연의 의미가 사라져가는 문제점을 파악하고 인디음악의 향후 방향에 대해 연구하기로 한다.

건축문화재의 지속가능한 보전방안으로 현대적 감각으로 그 가치를 실현시키는 것을 이야기 하고 있으며 그 실행 안으로 미디어 파사드를 제안하였다. 미디어 파사드는 기술과 예술의 결합으로 통합의 시대인 오늘날 가장 트랜디한 콘텐츠로 여겨진다. 따라서 미디어 파사드를 건축문화재에도 활용 가능할 때 프랑스 리옹시의 빛 축제 같은 새로운 콘텐츠 생산도 가능하리라 보고 있다. 그러나 최근 서울시 공공디자인 규제 법안으로 미디어 파사드 활용이 어려운 국면에 놓여있다. 이에 규제 법안과 그에 대한 해결점을 제시하였다.

Conventional stereoscopic (3D) displays using binocular parallax generate unnatural conflicts between convergence and accommodation. Those conflicts can affect the ability to fuse binocular images and may cause visual fatigue. This study examined time-series changes in visual fatigue and depth sensation while viewing stereoscopic images with changing parallax. We examined the physiological changes, including the subjective symptoms of visual fatigue, when viewing five parallax conditions. The time-series results suggest that 2D and 3D images produce significantly different types of visual fatigue over the range of binocular disparity.

Despite the fact that the deployment of sensor networks and target tracking could both be managed by taking full advantage of Voronoi diagrams, very little few have been made in this regard. In this paper, we designed an optimized barrier coverage and an energy-efficient clustering algorithm for forming Vonoroi-based Wireless Sensor Networks(WSN) in which we proposed a mobile target tracking scheme (CTT&MAV) that takes full advantage of Voronoi-diagram boundary to improve detectability. Simulations verified that CTT&MAV outperforms random walk, random waypoint, random direction and Gauss-Markov in terms of both the average hop distance that the mobile target moved before being detected and lower sensor death rate. Moreover, we demonstrate that our results are robust as realistic sensing models and also validate our observations through extensive simulations.

There is urgent need for effective and cost-efficient data storage, as the worldwide requirement for data storage is rapidly growing. DNA has introduced a new tool for storing digital information. Recent studies have successfully stored digital information, such as text and gif animation. Previous studies tackled technical hurdles due to errors from DNA synthesis and sequencing. Studies also have focused on a strategy that makes use of 100-150-bp read sizes in both synthesis and sequencing. In this paper, we a suggest novel data encoding/decoding scheme that makes use of long-read DNA (~1,000 bp). This enables accurate recovery of stored digital information with a smaller number of reads than the previous approach. Also, this approach reduces sequencing time.

본 연구는 서울특별시 275만명의 교통약자들이 서울시내 대중교통의 중심인 지하철 이용에 막대한 영향을 미칠 수 있는 지하철 역내의 승강 및 편의시설 위치 및 설치 정보를 수집하여 데이터베이스 시스템으로 구축하였다. 이를 바탕으로 장애인을 비롯한 교통약자들이 쉽게 이동여부를 판단할 수 있도록 승강시설의 위치와 장애인화장실의 여부, 수어영상전화기의 수, 전동휠체어 급속충전기의 여부 등을 비롯하여 지하철내 장애인 편의시설의 설치 정보를 제공한다. 나아가 지하철의 승강시설의 수와 실태는 서울시 및 교통공사 등 신규 시설 구축을 위한 이해관계자들의 기초 데이터로 활용이 가능한 점에서, 교통약자들의 편의 시설 개선을 위해 활용될 수 있다고 사료된다.

The purpose of this study is to analyse factors affecting performance of Global Outsourcing of the Korean Export-Importing Companies. This study aims to confirm the cause and effect relationship between independent variables; Organization Competency, Flexibility, Information Sharing and Partnership and dependent variable; the performance of Global Outsourcing. Also, another objective of this study is to discover affecting levels for the performance and activation factors of global outsourcing and to contribute to diffusion of global sourcing. This paper examined the concept and features of global sourcing and the present situation of global outsourcing at the level of domestic and overseas. From precedent studies that based on empirical studies about the transaction theory and the resource-based theory, we have derived a model with hypothesis and scale items then we conducted a survey of the Korean Export-Importing companies and empirically analysed the data. Before hypothesis testing, we conducted a basic information analysis in order to discover implication level of Global Soucring and also did reliability analysis and exploratory factor analysis using SPSS 18.0. Finally, the four hypothesis for the performance of Global Sourcing were tested with a regression model.

The purpose of this essay is three-fold: to trace the genealogy of the Korean musical, which ever since its inception in the 1960s has been seeking to modernize Korean theater with Broadway as a constant role model; to investigate how the national and the global conflict and are conflated in the form of the Korean musical in the process of its (dis)identification with Broadway; and to examine how its intercultural translations reveal and reflect the dilemma and ambivalence posed by globalization in our era. Drawing on Richard Dyer's signature article Entertainment and Utopia, I analyze how the Korean musical manifests and conduits competing utopian impulses of Korean/Global audiences. I also attempt to problematize the formulaic notion of Broadway musicalsthe Superior Other!which implies a global hegemony that does not, in fact, exist because the boundary between the global and the local as well as the power dynamics of global culture are not fixed but constantly moving and changing. Today's musical scene in Korea shows interesting reversals from the 1990s, when Korean producers were eager to debut on Broadway and impress American audiences. Korean producers no longer look up to Broadway as a final destination; instead they want to make Seoul a new Broadway. They import Broadway musicals and turn them into Korean shows. The glamor of Broadway is no longer the main attraction of musicals in Korea. What young audiences look for most is the glamor of K-pop idols and utopian feelings of abundance, energy, intensity, transparency and community, which they can experience live in the musical with their favorite stars right in front of their eyes. In conclusion, I delve into the complex dynamics of recent Korean musicals with Thomas Friedman's theory of Globalization 3.0 as reference. The binary formula of Global/America versus Local/Korea cannot be applied to the dynamic and intercultural musical scene of today. Globalization is not a uniform phenomenon but rather a twofold (multifold) process of global domination and dissemination, in which the global and the local conflict and are conflated constantly. As this study tries to illuminate, the Korean musical has evolved in a huge net of interdependences between the global and the local with a range of sources, powers and influences.

The vacuum drying process for drying of paper in current transformers was modeled with an aim to develop an understanding of the drying mechanism involved and also to predict the water collection rates. A molecular as well as macroscopic approach was adopted for the prediction of drying rate. Ficks law of diffusion was adopted for the prediction of drying rates at macroscopic levels. A steady state and dynamic mass transfer simulation was performed. The bulk diffusion coefficient was calculated using weight loss experiments. The accuracy of the solution was a strong function of the relation developed to determine the equilibrium moisture content. The actually observed diffusion constant was also important to predict the plant water removal rate. Thermo gravimetric studies helped in calculating the diffusion constant. In addition, simulation studies revealed the formation of perpetual moisture traps (loops) inside the CT. These loops can only be broken by changing the temperature or pressure of the system. The change in temperature or pressure changes the kinetic or potential energy of the effusing vapor resulting in breaking of the loop. The cycle was developed based on this mechanism. Additionally, simulation studies also revealed that the actual mechanism of moisture diffusion in CT's is by surface jumps initiated by surface diffusion balanced against the surrounding pressure. Every subsequent step in the cycle was to break such loops. The effect of change in drying time on the electrical properties of the insulation was also assessed. The measurement of capacitance at the rated voltage and one third of the rated voltage demonstrated that the capacitance change is within the acceptance limit. Hence, the new cycle does not affect the electrical performance of the CT.
