High performance concrete containing silica fume for use in bridge deck overlay emerged as a viable type of bridge deck overlay that economic advantage in construction. They have gained acceptance in Europe, America and Canada in a relatively short time due to their low cost. In this study, high-performance concretes containing silica fume were tested and evaluated in the laboratory to assess their applicability for use in bridge deck overlay. It was conducted with experiments of mechanical and durability characteristics in compressive strength, flexural strength, chloride permeability, abrasion resistance, repeated freezing and thawing cycles and deicing salt scaling resistance. Laboratory test result describe that high-performance concrete containing silica fume for bridge deck overlay application shows most outstanding capacity.

The purpose of this study is to draw implications for improving the method of reflecting the competencies in Korea mathematics curriculum, by analyzing what competencies are reflected in foreign mathematics and curriculum. As a result of the study, foreign countries were reflecting their competencies in mathematics curriculum in various ways. In France mathematics curriculum, the achievement standards of learning competencies(compétences travaillées) that students should reach by cycle were presented, and the related common competencies(socle commun) were indicated. In Australia's mathematics curriculum, the general capabilities for achievement standards were identified, and the achievement criteria for proficiency strands to be reached by grade level were presented. British Columbia's mathematics curriculum actively reflected its competencies. In the mathematics curriculum, domains were reorganized based on the competencies, and achievement standards of the competencies were proposed. The results of this study will help in improving the ways in which were reflected competencies in mathematics curriculum.

In order to establish the correct direction for the use of digital textbooks in the future, it is necessary to derive implications for improving the domestic digital textbook utilization policy by analyzing the actual conditions of other countries that are already using digital textbooks. Therefore, in this paper, we compared the policies of using digital textbooks in the United States, Canada, Malaysia, and China, and reviewed ways to improve Korea's digital textbook policies. First, each country's digital textbook promotion subject and strategy, scope of use, issuance system, and usage method were compared, and then the implications of each country's digital textbook policy were analyzed. And based on these implications, a plan to improve Korea's digital textbook policy was suggested. It is expected that this will be used as meaningful basic data in preparing policies for the development of digital textbooks in the future.

Chemical analyses and Rietveld structural refinement with powder X-ray diffraction data were done for Nb-rich perovskite, named latrappite ($Ca_2NbFe^{3+}O_6$)from the Oka, Quebec, Canada. Latrappite is shown to be a member of a continuous solid solution of $CaTiO_3-NaNbO_3-Ca_2NbFe^{3+}O_6$ and approximately $(Ca_{1.5}Na_{0.4})\;(Nb_{0.1}Ti_{0.6}Fe_{0.4})O_6$ in composition. The crystal structure of latrappite, determined by Rietveld refinement, is similar to that of perovskite ($CaTiO_3$). It differs in that replacement of Ti by Nb and $Fe^{3+}$ results in greater distortion and tilting of the $TiO_6$ framework octahedra relative to $CaTiO_3$. Revised unit-cell parameters of latrappite are a=5.4474(4), b=5.5264(4), c=7.7519(5) ${\AA},\;V=233.4(3){\AA}^3$ space group Pbnm.

To provide basic information for Verticillium spp., molecular methods were applied to analyze genetic characteristics within Verticillium spp. including Verticillium dahliae, isolated from diseased plants in two regions of Korea. Five Korean isolates of V. dahliae causing Verticillium wilt on chrysanthemum were analyzed, together with six other Verticillium spp., using mitochondrial small subunit rRNA gene (rns) sequence and random-amplified polymorphic DNA (RAPD). In a phylogenetic tree based on rns region sequences, Korean V. dahliae isolates formed a single clade with foreign isolates, whereas the other Verticillium spp. formed separate groups. In addition to rns sequence analysis, a dendrogram based on RAPD fragment patterns also showed clustering of all V. dahliae isolates into one group, separate from the six different Verticillium spp., and the V. dahliae isolates formed three subgroups which corresponded to the regions of origin, Kumi, Busan city and Canada. This indicates that high genetic variation exists between regions, although the fungus was isolated from the same host plant, chrysanthemum. These results provide the foundation for the study of genetic diversity and relationships among V. dahliae isolates in Korea.

Pelitic rocks of southwestern Nova Scotia have been affected by widespread contact metamorphism due to the intrusion of the Shellburne Pluton, with aureole up to 15 km wide. Well-preserved pseudomorphic textures indicate that common staurolite and andalusite metacrysts formed at the expense only of plagioclase, muscovite and biotite. Excess components (K, Na and Ca) from such replacement reactions imply extensive metasomatism throughout the contact aureole. Modal analysis of a typical andalusite-bearing rock indicates a one-to-one volume ratio of product to reactant. However the products of the replacement reactions contain approximately three times more aluminum than the reactants, indicating that the regional metasomatism also involved aluminum.

Purpose: This methodological study translated, adapted, and validated the evidence based guideline of RNAO (Registered Nurses Association of Ontario) in Canada, for acute stroke care to domestic circumstances. Methods: Quality of the RNAO guideline was evaluated using AGREE tool. Then the guideline was translated into Korean and a preliminary guideline was established After checking content validation by an expert group, the Korean version of the guideline was applied to clinical settings to see its applicability. Results: The RNAO guideline in Korea was deemed appropriate. The Korean version of the guideline was drawn up with 56 items in 3 areas in stroke system related nursing, nursing of acute stroke inpatients, and stroke nursing assessment. A questionnaire survey was performed on appropriateness, enforceability, and applicability of those recommendations. A total of 54 recommendations were finalized after deleting 2 items below CVI 0.7 and correcting 3 items by taking professional advices. After trial application of the guideline to 40 stroke patients hospitalized at a ward of a hospital in Seoul, its performance was improved but was not statistically significant. Conclusion: This guideline is expected to contribute to improving nursing quality by offering it as a guide to evidence based practices for acute stroke care in Korea.

2-D transport model based on a discrete probability distribution for a particle displacement was developed too solve advection-diffusion problems in natural stream. In this proposed model, the probabilities expressed as an average and variance function were used to predict the mass transfer between cells in one time step. The proposed model produces solutions without numerical dispersion for constant velocity, diffusion coefficient, and cross-sectional area. When the stability and positivity restrictions were satisfied, the model produced excellent results compared to analytical solutions and other finite difference methods. The proposed model is tested against the dispersion data collected in the Grand River, Canada. The simulation results show that the proposed model can properly describe the two-dimensional mixing phenomena in the natural stream.

The purpose of this study is to explore the Canadian Film Director Sophie Deraspe's . Director Sophie Deraspe adapted a Greek Sophocles's novel to the Film in a modern way. For this study, adopt two research methodologies which are 'Author-structuralism' and 'culture studies', and explore traits of esthetics, narrative, subject and context meaning by analyzing . This study concludes that Firstly director Sophie Deraspe is a 'Quebecious writer-director' who represents cultural identity of contemporary Qubec, Secondly, express immigrants in Qubec using Greek Sophocles's novel tragedy as an allegory in narrative, Thirdly, enhances the dramatic effect in esthetics using virtual mise-en-scene as insert, fantasy, SNS, etc. And lastly, can confirm re-territorializing the cultural identity from the distinct characteristics of regional past tradition to the universal hybridity discours in subject. Therefore, Sophie Deraspe's is a work that symbolizes a new trend of 'New Quebec Cinema' in Canada.
