Eco printing offers the perfect balance between getting all our printing jobs done without endangering the environment. It is important to realize that the printing industry is no exception to this rampant destruction of the planet's natural resources. In fact, surprisingly enough, its effect on the environment is an extremely harmful one. Like most other production operations, printing houses also produce harmful waste products that pollute the air we breathe in. They also put a great drain on precious natural resources. Printing houses emit what are known as volatile organic compounds (VOCs), caused by the use of petroleum-based inks, laminates, varnishes and adhesives. Studies show that these compounds, when inhaled, greatly increase the risk of asthma attacks. Eco printing, however, has a larger scope than is apparent. Eco printing has a dual essence. In order to understand what it is really all about, the issue of conservation is no less important than the need to stop polluting the environment.

Earth tide observations were taken at AMIST observatory in Seoul by LaCoste-Romberg ET gravimeter from September 2 to 16, 1997 for determining the gravimetric factor ($\delta$) and analyzing the tidal components. Meter drifts were corrected by regression and then denoised by threshholding wavelet, a data processing tool. The mean value of $\delta$ is 1.2 and the mean phase lag of & ($M_2$, $S_2$) and & $K_1$, $O_1$) is $0.07{\pm}0.03^{\circ}$ and $0.08{\pm}0.07^{\circ}$ by analyzing the observed earth tides. For yielding measurements of gravity accurate to about 0.01 mgal, the Earth tide observations are required by ET meter. The tidal variations are due to the planet's distance and zenith angle. With the exception of Earth-Moon and Earth-Sun mechanism, the possible causes of tidal variations are tectonical, meterological and hydrological perturbations. The long period and broad observations are required for determining the state of art gravimetric factor in Korea.

The scientific objectives of PACRIM (Pacific Rim) are to advance the understanding of polarimetric and interferometric radar and to promote its application in environmental research designed to detect and quantify changes found in both the physical and humanly dominated ecosystems on the earth's surface. The information derived is used to more readily identify environments at risk; improve environmental decision making and the management of resources and thereby lead to the implementation of more effective and sustainable land use practices. PACRIM is a collaborative research project was organized by NASA's Mission to Planet Earth, Airborne Sciences Program; the Jet Propulsion Laboratory; CSIRO-COSSA and the Centre for Remote Sensing and GIS at the University of New South Wales. A decade of working with AIRSAR data (1993-2003) in the Australia-Asian-Pacific region has provided the opportunity for more than 400 investigators from 20 countries to collect, analyse, interpret and apply state-of-the-art radar data to earth-science studies. This has been achieved by scientists working within seven broad research themes; o Forestry and vegetation o Geology and tectonic processes o Interferometry o Disaster management o Coastal analysis o Agriculture o Urban and regional development. This paper presents an overview of the three data acquisition missions (1993,1996 and 2000) and the science research outcomes achieved from analyzing high quality radar data.

In this paper, we propose a high-quality stitching method of 3D multiple dental CT images. First, a weighted function is generated using the difference of two distance functions that calculate a distance from the nearest edge of an overlapped region to each position. And a blending ratio propagation function for two gradient vectors is parameterized by the difference and magnitude of gradient vectors that is also applied by the weighted function. When the blending ratio is propagated, an improved region growing scheme is proposed to decide the next position and calculate the blending intensity. The proposed method produces a high-quality stitching image. Our method removes the seam artifact caused by the mean intensity difference between images and vignetting effect. And it removes double edges caused by local misalignment. Experimental results showed that the proposed method produced high-quality stitching images for ten patients. Our stitching method could be usefully applied into the stitching of 3D or 2D multiple images.

We all know how beautiful our wild and it's importance to our living planet Earth. But did you realise the speed at which man himself is damaging it's unique natural habitat. We are well on our way to destroy our forests, plants, wetlands. We are polluting our oceans and seas. This way, we're driving numerous animal species, plant species and many others into extinction. Everyone should be aware of the importance of our natural environment. We live in the period of echocide. Why we need nature to survive and how we can deal with the environmental problems we face. This paper has the purpose to reform city's environment. Because, Metropolis and megalopolis are the principal cause of environmental disruption. To reform the city is needed to consider digital technology in our age. In the face of economic and cultural globalization, many have argued that we live an increasingly placeless world. However, as a growing number of cities participate and compete in key marketplaces of advanced capitalism, the spectacle of the city is more than ever a significant medium of communication in its own right. In doing so, this work is focused specifically on the dimension of city's media environment. To that end, the paper examined U-City and U-Eco city. In this study, we will introduce the study on model of U-Eco City as one way for the eco-freindly future city.

In order to achieve faster content distribution speed and stronger fault tolerance, a P2P peer can connect to multiple peers in parallel and receive chunks of the data simultaneously. A critical issue in this environment is selecting a set of nodes participating in swarming sessions. Previous related researches only focus on performance metrics, such as downloading time or the round-trip time, but in this paper, we consider a new performance metric which is closely related to the network and propose a peer selection algorithm that produces the set of peers generating optimal worst link stress. We prove that the optimal algorithm is practicable and has the advantages with the experiments on PlanetLab. The algorithm optimizes the congestion level of the bottleneck link. It means the algorithm can maximize the affordable throughput. Second, the network load is well balanced. A balanced network improves the utilization of resources and leads to the fast content distribution. We also notice that if every client follows our algorithm in selecting peers, the probability is high that all sessions could benefit. We expect that the algorithm in this paper can be used complementary to existing methods to derive new and valuable insights in peer-to-peer networking.

This paper aims to look into various symbolic meanings of the body shown in the film, Avatar (2009, James Cameron), and to ponder over a variety of media strategies carried by the pursuit of the corporality shown in this film. In a nutshell, the body in Avatar is a symbol of primitiveness rather than civilization, and the body language is a fundamental and effective means of communication much better than verbal language. A variety of physical contacts that appeared in many scenes of the movie emphasizes the role of the body as a means of real communication. Also, in the composition of the film dominated by the confrontation of civilization, numerous creatures in the planet Pandora with a variety of colors as well as a number of agencies and large body sizes express primitive richness. The narrative of the film telling the story of a 'moving' body ultimately emphasizes the superiority of the body with respect to consciousness, unlike the narrative of conventional movies dealing with the problems of the body. In addition, the corporality pursued by this film implies several important media strategies. It may reveal a self-reflection of the material civilization and the imperialism, or, on the contrary, an attempt to conceal or dilute them. It may also represent a self-reflection of the overdeveloped media technology, or simply the dilution of it. Finally, it may be an attempt to recover the feeling of "presence", not fully supported by the 3D technology, by the identification of the spectator's body and the character's body.

In this study, Cermet Reamers for planet carrier was manufactured and the machining characteristics were analyzed through processing experiment. Cermet reamer with ∅14, ∅15, ∅18, and ∅21mm was used and machining characteristics were compared and analyzed by observing tool wear, machining hole dimensions and surface roughness. In the flank wear of the tool, the result is less than 0.2mm, which is the target value for each tool size. The experimental results of the machining hole dimensions show the results of the process control range of 3/100 or less according to the size of the tool. Also, the surface roughness measurement result showed a value of less than $0.5{\mu}m$ in the process control range for each tool size. As a result of observing the experimental results of each ∅, the results satisfied the process standard in both the tool wear, the machining hole dimension and the surface roughness.

This article examined the historical evolution of changes in the democratization of fashion, identified its characteristics, and defined 'fashionocracy - fashion democracy'- by analyzing various phenomena in the global fashion industry. This research will expand the field of fashion research and spark academic debates about fashion democracy. The democratization of fashion can be summarized in five periods; birth, introduction, early growth, growth, and maturity. The characteristics of the democratization of fashion include individual autonomy, accessibility that many people can access and enjoy, and diversity. According to the principles of democracy- "of the people, for the people, by the people" - which are based on freedom and equality, we have achieved fashion of the people and for the people so far. Furthermore, social media has shifted the balance of power to influencers and bloggers; as such, the masses who have consumed and enjoyed fashion democratization are becoming producers and promoters by actively participating in the process of making fashion, creating a new era of fashion democracy (fashionocracy): - by the people. Ultimately, fashionocracy consists of the '6P's' ; people (active and productive consumers), planet (society and environmental sustainability), products (genderless, ageless, inclusive), price (reasonable), place (multi-channel distribution, virtual spaces), and promotion (horizontal).
