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.

Over the past few years, extensive research has been focused on the development of rare-earth-free phosphors to achieve energy-efficient and cost-effective WLEDs with high luminous efficiencies for solid-state lighting applications. Herein, we report a novel rare-earth-free self-activated blue phosphor Ca2Sb2O7, synthesized by solidstate reaction method. The electronic structure and bandgap of the material were determined by the density functional theory (DFT + U) method using Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional. The prepared phosphor could be effectively excited in the range 280–370 nm resulting in a broad blue emission band, owing to the Sb5+ → O2- transition in the (SbO6)7- group. The CIE chromaticity coordinates were found to be (0.144, 0.097) indicating intense blue emission with high color purity of 89%. Also, the prepared phosphor has good thermal stability and an internal quantum efficiency of 24%. All these results indicate that self-activated Ca2Sb2O7 could be a potential blue phosphor for lighting and display devices.
Radiologically inserted gastrostomy complications: A case series
George Zhang,Hayden Matthews,Osanna Wong,Dylan Kurda 소화기인터벤션의학회 2022 Gastrointestinal Intervention Vol.11 No.3
Radiologically inserted gastrostomy (RIG) is performed in patients who cannot safely or sufficiently receive oral nutrition; however, postoperative complications are not uncommon. The risk of major complications such as peritonitis, migration, infection, malposition, and bleeding is small but appreciable, although mortality as a direct consequence of gastrostomy placement is rare. In this case series, we describe the major gastrostomy complications (arterial haemorrhage, gastric fluid leak, peritonitis, RIG site infection, ileus and colon perforation) that occurred in four patients at our hospital over a 27-month period in which 152 RIG procedures were performed (an incidence rate of 2.6%). Herein, we describe the gastrostomy procedures, clinical course, and surgical corrections required for these patients before discussing the complication risks for common gastrostomy procedures and potential methods to reduce and prevent such complications.
