A Supportable Format for Attribute Based Encryption in Cloud Computing

George,Salu 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-

Cloud Computing is used for enabling convenient, on-demand network to access shared pool of configurable computing resources (e.g. Networks, servers, storage, applications, and services) which are rapidly provisioned and released with management effort or service provider interaction. Cloud technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. The security is the major issue in the cloud computing. The issue is overcome by the encryption. The various encryption standards ensure the cloud security. Attribute-based encryption (ABE) is a vision of public key encryption that allows users to encrypt and decrypt messages based on user attributes. In a typical implementation, the size of the cipher text is proportional to the number of attributes associated with it and the decryption time is proportional to the number of attributes used during decryption To reduce the decryption time in outsourced encryption method the user provides a transformation key to the cloud to translate any ABE cipher text into simple cipher text and it only incurs a small computational overhead for the user to recover the plaintext from the transformed cipher text. The proposed system introduces the Verifiable Outsourced Encryption so that the user can check the correctness of the transformation performed by the cloud server and the user let to know the data is not modified by the untrusted servers.

Diverse Nation, Diverse Curriculum: Multicultural Education in Canada’s Public Schools

George H. Richardson(George H. Richardson ),Saearm Yi(Saearm Yi),Monica Chahal(Monica Chahal ) 한국캐나다학회 2016 Asia-Pacific Journal of Canadian Studies (APJCS) Vol.22 No.1

Multicultural education has been an integral component of Canadian public education for more than 40 years. As might be expected with any element of public education that is more than 4 decades old, the nature and intent of multicultural education in Canada has evolved over time and has become a mirror of the changing ways in which Canada has imagined its increasingly diverse population and its national identity, In this paper, we examine multicultural education in three particular aspects. First, we describe the social and political context of multiculturalism in Canada. Second, we focus on multicultural education in provincial curriculum with special emphasis on the province of Alberta, and finally, we take up the more recent shift in multicultural education that suggests that the discipline can be viewed as a form of citizenship education. In our conclusion we touch briefly on education in Korea to return to the idea that national contexts have a significant influence on the ways in which multicultural education is understood and delivered.

论哲学对营销思想的促进作用

George Panigyrakis,신건철 한국마케팅과학회 2014 마케팅과학연구 Vol.24 No.3

The four papers s in this special issue e revisits the e core e concepts s and key functions of marketing through philosophy. They examine the e discipline e as it enters s its maturity amidst unprecedented global socioeconomic turmoil. As the certainties of modernity and the individualism of postmodernity melt into the uncharted lands of metamodernity, they offer a kaleidoscopic view of the big issues faced by contemporary societies through a fascinatingly eclectic mix of topics, theoretical frameworks and methodological perspectives. They call for a clean break from amoralism and a wholehearted embracement of our role as facilitators of value coproduction and agents of the e ethics of gentleness.

The "Highest Court" In Federal Systems

( George A. Bermann ) 국제헌법학회, 한국학회 2005 世界憲法硏究 Vol.11 No.2

The courts of last resort within States bear an enormous responsibility for the law, since unless and until the political branches of government have spoken, it is these courts, that ultimately decide what the law means, and it is they who take responsibility for legal coherence within the polity they serve. Of course, even that statement does not go nearly far enough: some - not all - highest courts also determine whether and to what extent decisions taken by the political branches comply with the polity`s basic constitutional precepts and are entitled to be enforced. Such "highest courts" are thus also "constitutional" courts in the fullest sense of that term. My focus is highest courts in federal systems, and federal systems immediately raise threshold definitional issues. First, what is the "highest court" in a federal system? Is it, almost as if definitionally, the highest court at the federal level? Or does it also include (within a sphere that has to be delineated of course) the highest courts at the level of the constituent states? Second, when there happens to be a multiplicity of nominally supreme courts at either the state or the federal level, which court is "the highest" among them? Is it the court or court whose job it is to give authoritative interpretations of legislation (to state what the law is - be it state or federal - and what it means), or is it the court - assuming that a separate one exists at the federal level for these purposes - that authoritatively determines the constitutionality of legislation, if challenged? All this is to say that, as in other areas of human endeavor - notably architecture - form follows function. It is idle to designate a court or courts as "highest" without first identifying the judicial functions to be performed. Thus, in a judicially complex federal system, there can be (a) a highest court and (depending on specialization) possibly several highest courts for the interpretation and understanding of the law of the constituent states. (b) a highest court for determinations of the constitutionality of constituent state law under the state constitution, (c) a highest court and (depending on specialization) possibly several highest courts for the interpretation and understanding of federal law, and (d) a highest court for determinations of the constitutionality of federal law, and possibly also state law, under the federal constitution. It is auspicious, for heuristic purposes, that we are sitting in Germany. But even this laborious catalogue of conceivable highest courts can be further complicated by the possibility of having yet a separate court - on the French Tribunal des Conflits model - whose function is to decide in which order of courts within a complex court system a given case belongs, in the event of conflict over that purely jurisdictional question. If I am correct that there are numerous logically defensible ways in which to organize "supreme" judicial authority within federal systems, the designers of federal constitutions have considerable architectural license. Whatever the drafters or the U.S. Constitution may have originally and specifically intended, they created - or left open - the possibility that centralized in the U.S. Supreme Court would be final authority to determine both the meaning and federal constitutionality of federal law and the federal constitutionality of state law. The further and related, but really not surprising, move that the Supreme Court made was to consider that questions of state vs. federal legislative competence represent constitutional questions and that, as such, their resolution therefore also fell within the Supreme Court`s purview. And so, it is today unquestioned - though it is still not inscribed in the U.S. federal constitutional document - that the Supreme Court would ultimately determine the outer limits of federal legislative authority and state legislative authority vis-a-vis each other. It has, we might say, Kompetenz/Ko

Mix Design and Properties of Recycled Aggregate Concretes

George Wardeh,Elhem Ghorbel,Hector Gomart 한국콘크리트학회 2015 International Journal of Concrete Structures and M Vol.9 No.1

This work is devoted to the study of fresh and hardened properties of concrete containing recycled gravel. Four formulations were studied, the concrete of reference and three concretes containing recycled gravel with 30, 65 and 100 % replacement ratios. All materials were formulated on the basis of S4 class of flowability and a target C35 class of compressive strength according to the standard EN 206-1. The paper first presents the mix design method which was based on the optimization of cementitious paste and granular skeleton, then discusses experimental results. The results show that the elastic modulus and the tensile strength decrease while the peak strain in compression increases. Correlation with the water porosity is also established. The validity of analytical expressions proposed by Eurocode 2 is also discussed. The obtained results, together with results from the literature, show that these relationships do not predict adequately the mechanical properties as well as the stress?strain curve of tested materials. New expressions were established to predict the elastic modulus and the peak strain from the compressive strength of natural concrete. It was found that the proposed relationship E?fc is applicable for any type of concrete while the effect of substitution has to be introduced into the stress?strain (ec1?fc) relationship for recycled aggregate concrete. For the full stress?strain curve, the model of Carreira and Chu seems more adequate.

Joseon Korea and Meiji Japan during the Great Opening: The Role of Nationalism in East Asia`s Globalization

( George Baca ) 아시아.유럽미래학회 2013 유라시아연구 Vol.10 No.4

“Globalization” is neither new nor ill-disposed to the authority of the nation-state. In South Korea, since the 1990s, it has become popular to think that the new age of globalization (segyehwa) has weakened the power of the state and forced national governmnents to hand over greater amounts of sovereignty to global markets. Such a view resonates with academic arguments that often use the concept of globalization to create the sense that the flow of capital across national borders is not only novel but also undermines the power of the nation-state. This paper argues against these views by showing the ways in which global capital created the conditions from which the modern nation-state and nationalism emerged in Japan and Korea. With Britain’s invasion of the Qing Dynasty, European capital and imperial policies began the gradual dismantling of the Chinese Empire’s East Asian interstate system. In its place emerged a new form of state power that was rooted in capitalist relations and legitimized by mythologies of the nation. From this conjuncture Meiji Japan was the first sovereign in East Asia to embrace the European structure of the nation-state and industrial capitalism. Japanese nation builders fashioned an image of the nation that was conducive to participating in the global system of capitalism. The emergent Japanese nation-state illustrates the role of nationalism in the spread of global capitalism in Asia during the nineteenth century. Meiji reformers adopted the structure to the nation-state to reorganize Japanese society, as well as Asian interstate relations, in terms of industrial capitalism. Central to this project was the colonization of Korea. By using the European model of imperialism, Meiji Japan redefined Korea as a nation and inspired a nationalist movement among reformers in Joseon society. Nationalism, and the national state, figured centrally in the processes of economic integration that is now known as globalization of East Asia.

Comparative Studies to Evaluate Relative in vitro Potency of Luteolin in Inducing Cell Cycle Arrest and Apoptosis in HaCaT and A375 Cells

George, Vazhapilly Cijo,Kumar, Devanga Ragupathi Naveen,Suresh, Palamadai Krishnan,Kumar, Sanjay,Kumar, Rangasamy Ashok Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Luteolin is a naturally occurring flavonoid present in many plants with diverse applications in pharmacology. Despite several studies elucidating its significant anti-cancer activity against various cancer cells, the mechanism of action in skin cancer is not well addressed. Hence, we investigated the effects of luteolin in HaCaT (human immortalized keratinocytes) and A375 (human melanoma) cells. The radical scavenging abilities of luteolin were determined spectrophotometrically, prior to a cytotoxic study (XTT assay). Inhibitory effects were assessed by colony formation assay. Further, the capability of luteolin to induce cell cycle arrest and apoptosis were demonstrated by flow cytometry and cellular DNA fragmentation ELISA, respectively. The results revealed that luteolin possesses considerable cytotoxicity against both HaCaT and A375 cells with $IC_{50}$ values of 37.1 ${\mu}M$ and 115.1 ${\mu}M$, respectively. Luteolin also inhibited colony formation and induced apoptosis in a dose and time-dependent manner by disturbing cellular integrity as evident from morphological evaluation by Wright-Giemsa staining. Accumulation of cells in G2/M (0.83-8.14%) phase for HaCaT cells and G0/G1 (60.4-72.6%) phase for A375 cells after 24 h treatment indicated cell cycle arresting potential of this flavonoid. These data suggest that luteolin inhibits cell proliferation and promotes cell cycle arrest and apoptosis in skin cancer cells with possible involvement of programmed cell death, providing a substantial basis for it to be developed into a potent chemopreventive template for skin cancer.

A 0.8 V Supply- and Temperature-Insensitive Capacitance-to-Digital Converter in 0.18- <tex> $\mu \text{m}$</tex> CMOS

George, Arup K.,Junghyup Lee,Zhi Hui Kong,Minkyu Je IEEE 2016 IEEE SENSORS JOURNAL Vol.16 No.13

<P>A low-voltage, low-power, capacitance-to-digital converter (CDC) that is insensitive to supply and temperature variations is presented in this paper. The CDC comprises two matched RC oscillators and a counter-based programmable digital converter. The transfer function of the proposed CDC is a scaled ratio of the capacitors having equal drift coefficients, making it insensitive to supply as well as temperature variations. Worst case temperature-dependent drift of +/- 153.4 ppm/degrees C is measured between -40 and +120 degrees C while worst case supply-dependent drift of +/- 1.12% is measured between 0.8 and 1.2 V over full-scale capacitance range. The proposed CDC achieves 2.05 fF resolution, consuming 23 mu A from a 0.8 V supply, at a full-scale range of 3.36 pF. The CDC, realized in 0.18-mu m CMOS process, has an active area of 0.102 mm(2) and offers a scalable resolution within a range of 2-13 b.</P>
