  • KAERI has developed DUPIC nuclear fuel with the refabrication of spent PWR fuel discharged from domestic nuclear power plant by a dry process at M6 hot-cell in IMEF To verify the performance of DUPIC nuclear fuel, irradiation test at the operating conditions of commercial power plant is essential. Since the HANARO research reactor of KAERI does not have fuel test loop(FTL) for irradiating nuclear fuel under high temperature and high pressure conditions, DUPIC fuel cannot be irradiated in the FTL of HANARO. In the 13-th PRM among Korea, Canada, USA and IAEA, AECL proposed that KAERI fabricated DUPIC fuel can be irradiated in the FTL of the NRU research reactor without charge of neutrons. The transportation quantity of DUPIC fuel to Canada is 10 elements(about 6kg). This transportation package is classified as the 7-th class according to "recommendation on the transport of dangerous goods" made by the United Nations. In case of air shipment, until now, there is no proper air transportation cask for DUPIC fuel. In case of sea transportation is possible but requires very high cost.high cost.

  • Social co-operatives, which are working positively to realize the economic and social purpose of being carried out directly through products and services producing the public interest, are steadily expanding under the public interest mission of social co-operatives. It has important theoretical and practical significance to study the model of social co-operatives tailored to the local situation in Korea based on international experience. This study looks at the international status of social co-operatives, international cases, and puts forward problems and suggestions centering on cases of advanced countries. It sought to find a solution to what society required only by solving the problems necessary for sustainable economic growth. In order to achieve the objectives of this study, the social cooperatives of advanced countries, such as Italy, Canada, and France, were organized, compared and analyzed. The study found that the implications of co-operatives in Italy, France and Canada are as follows. First, it is needed to adhere to the principles of co-operatives in pending issues such as social problems and employment and jobs in the community. Second, it is necessary to establish a supportive financial system for the cooperative's initial stability and sustainability. Third, the ecosystem of co-operatives should be formed to support and foster legal systems and network organizations.

  • As global climate change is expected to influence regional water resources, water resource managers need to establish adaptive management to cope with climate change. We examined adaptive management efforts in the US, UK, Canada, Australia, and the Netherlands. Each country is implementing different levels of adaptation efforts based on current water management practices, institutional arrangements, as well as the varying degree of water availability, current climate effects and expected climate change effects. Based on the comparison of these countries, we suggest policy implications for the sustainable water resource management of Korea under climate changes.

  • Purpose: The paper analyzes for detecting unexpected shocks such as global financial crisis and COVID-19 pandemic, and contagion between countries by capturing in the mean-shift, variance-covariance-shift, and skewness-coskewness-shift parameters of interest rates. Research design, data and methodology: A flexible multivariate model of interest rates is provided by allowing for regime switching and a joint skewed normal distribution. The model is applying to the structural breaks of crisis and contagion between the US and the selected global bond markets during the global financial crisis and COVID-19 pandemic, respectively. Inspection of the moment statistics weakly suggests a flight to safety to the US during the global financial crisis and to Canada during the COVID-19 pandemic. Results: The results indicate that risk averse investors had a higher risk appetite for the US and Canada assets during the crisis regimes, compared to their counterparts. Conclusions: The results show that coskewness contagion dominates correlation contagion, and coskewness contagion is significant for the Korea and Japan-US pairs for the global financial crisis and the Euro-US pair for the COVID-19 pandemic. All channels of structural breaks of crisis and contagion are significant when considered jointly, reinforcing the need to consider contagion and structural breaks during crises in a multivariate setting.

  • United States of America started NSDI in 1994 for the first time in the world. EU and other many countries invested lots of budget on NSDI due to necessity to manage countries and social economy. As skepticism for effect of such investment has risen, developed countries predicted higher effect compared to investment using ROI and other methods. FGDC clarified that geospatial information is a critical national assets. USA has managed NSDI by introducing portfolio concept for it recognizing NSDI as financial assets from fixed assets. Currently directions of NSDI and its advancement has been proceeded variably depending on corresponding organizations, human resources, budget and national policies. This study analyzed recent trends regarding NSDI assessment methods from developed countries and researchers. Assessment of NSDI is introduced only by some countries such as EU, USA and Canada. This study analyzed USA's assessment model and indicator that assess NSDI in a way that various external organizations (COGO, URISA) participate, EU INSPIRE Directives, monitoring and Canada's CGDI assessment methods. Besides these, this study analyzed STIG that adopted Financial Infrastructure from European studies and Korea's NSDI monitoring assessment indicator research. Further this study suggested assessment directions for future NSDI through implications of NSDI assessment method analysis.

  • Time-loss injuries are still a major occurrence in Canada, injuring thousands of Canadian workers each year. With obesity rates on the rise across the country, as well as around the world, it is important that the possible effects of obesity in the workplace be fully understood, especially those effects linked to lost-time injuries. The aim of this paper was to evaluate predictors of workplace lost-time injuries and how they may be related to obesity or high body mass index by examining factors associated with lost-time injuries in the health care sector, a well-studied industry with the highest number of reported time loss injuries in Canada. A literature review focusing on lost-time injuries in Registered Nurses (RNs) was conducted using the keywords and terms: lost time injury, workers' compensation, occupational injury, workplace injury, injury, injuries, work, workplace, occupational, nurse, registered nurse, RN, health care, predictors, risk factors, risk, risks, cause, causes, obese, obesity, and body mass index. Data on predictors or factors associated with lost-time injuries in RNs were gathered and organized using Loisel's Work Disability Prevention Management Model and extrapolated upon using existing literature surrounding obesity in the Canadian workplace.

  • Oil sands are sands containing bitumen similar to crude petroleum. Oil sands had not received enough interest because of the high production cost. However, in the current record-high oil price situation, oil sands are considered as new sources for unconventional oil. In this study, patents analysis was performed for the technologies of production of synthetic crude oil from oil sands. The patents covered were open patents applied in Korea, US, Canada, Japan, Europe, and China. The patents were divided into five detailed technologies; mining and in-situ, extraction, upgrading, fuelling, and other technologies. For oil sands technologies, there have been steady patent applications, since the first patent was applied in 1969. The number of patents applied appeared to be affected by the variation of world oil price. The portion of patents applied in US and Canada was about 90% of the overall patents and it means 05 and Canada have led oil sands technologies. Mining and in-situ technologies, and extraction have been developed actively and occupied more than 77% of the overall patents. However, the number of patents applied for mining and in-situ technologies, and extraction has been constant or started to decrease since 2000. The number of patents applied for upgrading technologies increases recently and it shows the development of upgrading technologies is active now.

  • In order to obtain the genetic informations of the Korean isolates of porcine circovirus 2 (PCV2), nucleotide sequences of total genome of three isolates and open reading frame 2 (ORF2) of four isolates were determined and compared with those of other reference PCV2 isolates. Nucleotide sequences of 3 isolates showed over 99% homology with those of reference strain (GenBank accession no. AF027217). Point mutations were mainly determined on ORF2 regions but little on ORF1 regions. The patterns of pointmutated sites and nucleotide substitution on ORF2 regions were generally consistent between Korean isolates, and these mutated sites observed in Korean isolates were also relatively similar to those of foreign isolates. Phylogenetic analysis of nucleotide or amino acid sequences showed that there were minor branches consisting of three clusters; cluster of Korea, Canada and America, cluster of Spain and Taiwan, and the last cluster of French and China isolates. These results suggested that Korean PCV2s were probably originated from North America such as Canada or USA. The genetic informations obtained from this study could be useful for the research of diagnosis and pathogenecity of PCV2.

  • The time consuming and expensive nature of experimental research on scouring processes caused by flowing water makes it attractive to develop numerical tools for the predication of the interaction of the fluid flow and the movable bed. In this paper the numerical simulation of scour by a wall jet is presented. The flow is assumed to be two-dimensional, and the alluvium is cohesionless. The solution process, repeated at each time step, involves simulation of a turbulent wall jet flow, solution of the convection-diffusion of sand concentration, and prediction of the bed deformation. For simulation of the jet flow, the governing equations for momentum, mass balance and turbulent parameters are solved by the finite volume method. The SIMPLE scheme with momentum interpolation is used for pressure correction. The convection-diffusion equation is solved for sediment concentration. A boundary condition for concentration at the bed, which takes into account the effect of bed-load, is implemented. The time rate of deposition and scour at the bed is obtained by solving the continuity equation for sediment. The shape and position of the scour hole and deposition of the bed material downstream of the hole appear realistic.

  • Moisture flow and heat flow within pavement systems have been recognized as coupled processes with complex interactions between them. The distribution of moisture and temperature within pavement due to the moisture flow and heat flow varies not only seasonally but also vertically and horizontally. This paper presents an analysis model by the finite element method for the two-dimensional coupled moisture and heat flow in unsaturated soils. To test the model the analysis result by the model is compared with the analysis result by the software, GEO-SLOPE developed by GEO-SLOPE International Ltd. in Alberta, Canada. And a sensitivity analysis using ASTM method is performed to identify how model inputs affect the modeling analysis.
