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.

Using Modal Parameters for On-Line Structural Faults Diagnostics

Richardson,Mark H. 대한기계학회 1993 Korea - U. S. Vibration Engineering Seminar Vol.1 No.1

Many types of structural faults, such as cracking, delamination, unbonding, loosening or wear out of fastened parts, etc., will cause changes in the measured vibration response of a machine or structure. These changes will, in turn, cause changes in the structure's experimentally derived modal parameters. Using this premise, a structural monitoring system which measures the vibration of a structure, identifies changes in its modal parameters, and predicts occurrences of structural faults could be built. Such a system would provide a level of accuracy far beyond the traditional peak picking of threshold crossing implementations of the past. Also, its implementation can benefit from a complete a priori knowledge of the structure's dynamic characteristics, which is contained in its modal properties. 1n this paper, several important issues associated with the use of experimentally derived modal parameters as a means of detecting structural faults are examined. Also included are some experimental results which demonstrate how modal parameters are changed by simulated faults.

Ag Nanoparticle/Polydopamine-Coated Inverse Opals as Highly Efficient Catalytic Membranes

Choi, Gwan H.,Rhee, Do Kyung,Park, A. Reum,Oh, Min Jun,Hong, Sunghwan,Richardson, Joseph J.,Guo, Junling,Caruso, Frank,Yoo, Pil J. American Chemical Society 2016 ACS APPLIED MATERIALS & INTERFACES Vol.8 No.5

<P>Polymeric three-dimensional inverse-opal (JO) structures provide unique structural properties useful for various applications ranging from optics to separation technologies. Despite vast needs for IO functionalization to impart additional chemical properties, this task has been seriously challenged by the intrinsic limitation of polymeric porous materials that do not allow for the easy penetration of waterborne moieties or precursors. To overcome this restriction, we present a robust and straightforward method of employing a dipping-based surface modification with polydopamine (PDA) inside the IO structures, and demonstrate their application to catalytic membranes via synthetic incorporation of Ag nanoparticles. The PDA coating offers and successful creation of nucleation sites for a reduction of growth of the Ag nanoparticles. The resulting Ag nanoparticleincorporated IC) structures are utilized as catalytic membranes for the reduction of 4-nitrophenol to its amino derivatives in the presence of NaBH4. Synergistically combined characteristics of high reactivity of Ag nanoparticles along with a greatly enhanced internal surface area of IO structures enable the implementation of remarkably improved catalytic performance, exhibiting a good conversion efficiency greater than 99% while minimizing loss in the membrane permeability.</P>

Electronic properties of intrinsically conducting polymer-cellulose based composites

M.J. Richardson,J.H. Johnston,T. Borrmann 한국물리학회 2006 Current Applied Physics Vol.6 No.3

In situ polymerisation of pyrrole, aniline and derivatives with cellulosic substrates provides composites with potentially useful properties. Conductivity relative to the untreated substrate is increased, and an inverse relationship of conductivity to dielectric, and hence capacitance is observed. A metallic layer such as copper may be deposited electrochemically onto the surface of the composite, and the metal surface may then be oxidised to form either the green carbonate patina commonly seen on bronze statues, or a deep red oxide layer. When the polymer used is polypyrrole, silver may be reduced onto the surface following reduction of the polymer via hydrazine or sodium borohydride. The composites have been characterised via scanning electron microscopy, impedance analysis, cyclic voltammetry and conductivity measurements.

Influence of Ionic Strength on the Deposition of Metal–Phenolic Networks

<P>Metal–phenolic networks (MPNs) are a versatile class of self-assembled materials that are able to form functional thin films on various substrates with potential applications in areas including drug delivery and catalysis. Different metal ions (e.g., Fe<SUP>III</SUP>, Cu<SUP>II</SUP>) and phenols (e.g., tannic acid, gallic acid) have been investigated for MPN film assembly; however, a mechanistic understanding of the thermodynamics governing MPN formation remains largely unexplored. To date, MPNs have been deposited at low ionic strengths (<5 mM), resulting in films with typical thicknesses of ∼10 nm, and it is still unclear how a bulk complexation reaction results in homogeneous thin films when a substrate is present. Herein we explore the influence of ionic strength (0–2 M NaCl) on the conformation of MPN precursors in solution and how this determines the final thickness and morphology of MPN films. Specifically, the film thickness increases from 10 nm in 0 M NaCl to 12 nm in 0.5 M NaCl and 15 nm in 1 M NaCl, after which the films grow rougher rather than thicker. For example, the root-mean-square roughness values of the films are constant below 1 M NaCl at 1.5 nm; in contrast, the roughness is 3 nm at 1 M NaCl and increases to 5 nm at 2 M NaCl. Small-angle X-ray scattering and molecular dynamics simulations allow for comparisons to be made with chelated metals and polyelectrolyte thin films. For example, at a higher ionic strength (2 M NaCl), sodium ions shield the galloyl groups of tannic acid, allowing them to extend away from the Fe<SUP>III</SUP> center and interact with other MPN complexes in solution to form thicker and rougher films. As the properties of films determine their final performance and application, the ability to tune both thickness and roughness using salts may allow for new applications of MPNs.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/langd5/2017/langd5.2017.33.issue-40/acs.langmuir.7b02692/production/images/medium/la-2017-026926_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/la7b02692'>ACS Electronic Supporting Info</A></P>

Physico-chemical confinement of helical nanofilaments

<P>Helical nanofilaments (HNFs) have attracted much interest because of their unique optical properties, but there have been many hurdles to overcome in using them for the practical applications due to their structural complexity. Here we demonstrate that the molecular configuration and layer conformation of a modulated HNF (HNFs<SUB>(mod)</SUB>) can be studied using a physicochemical confinement system. The layer directions affected by the chemical affinity between the mesogen and surface were drastically controlled in surface-modified nanochannels. Furthermore, an <I>in situ</I> experiment using grazing-incidence X-ray diffraction (GIXD) was carried out to investigate in detail the structural evolution through thermal transitions. The results demonstrate that the HNF<SUB>(mod)</SUB> structure can be perfectly controlled for functional HNF device applications, and a combined system with chemical and physical confinement effects will be helpful to better understand the fundamentals of soft matter.</P> <P>Graphic Abstract</P><P>Helical nanofilaments (HNFs) have attracted much interest because of their unique optical properties, but there have been many hurdles to overcome in using them for the practical applications due to their structural complexity. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c5sm00417a'> </P>

Decreased Catalytic Subunit mRNA Levels and Altered Catalytic Subunit mRNA Structure in a cAMP-resistant Chinese Hamster Ovary Cell line

Howard, Paul,Day, Kathleen H.,Kim, Kyoon E.,Richardson, Jeanne,Thomas, James,Abraham,Irene,Fleischmann, Robert D.,Gottesman, Michael M.,Maurer, Richard A. 충남대학교부설 생명공학연구소 1992 생물공학연구지 Vol.2 No.-

The mechansims responsible for decreased levels of cAMP-dependent protein kinase activity in a mutant Chinese hamster ovary cell line have been examined. The cAMP-resistant Chinese hamster ovary 10260 cell line was found to possess only 20% of the cAMP-dependent protein kinase activity found in wild-type cells. The pressence of decreased concentrations of the catalytic subunit in these cells was confirmed through binding studies using a radiolabeled, heat-stable inhibitor of the kinase. Cloned Chinese hamster ovary catalytic subunit cDNAs were isolated, characterized, and used as hybridization probes to examine the relative concentrations of catalytic subunit mRNAs in the wild-type and 10260 cell lines. A 40-50% decrease in the concentration of the mRNA for the Cα isozyme of the catalytic subunit was observed in 10260 cells, as compared with wild-type. This decrease in catalytic subunit mRNA concentration probably accounts for a portion of the decreased kinase activity in the mutant cell. Further analysis of Cα mRNA by polymerase chain reaction confirmed the decreased expression of Cα mRNA in 10260 cells and further demonstrated the presence of two different species of Cα cDNAs was indistinguishable from the wild-type cDNA, but the other species was shorter. Nucleotide sequence analysis of the amplified cDNAs led to the identification of a 191-base pair deletion in the shorter cDNA. Gene transfer studies using wild-type and 10260 Cα cDNAs demonstrated wild-type activity, but the shorter cDNA was inactive. These studies suggest that at least two alternations in gene expression are responsible for decreased cAMP-dependent protein kinase activity in the 10260 cell line. One alteration results in an approximately 2-fold decrease in the concentrations of Cα mRNA in the cells.
