In this study, we challenge recent apocalyptic rhetoric about idle, burdensome, and dependent older people. Our primary objective is to examine and compare the productive activities of older adults in both Korea and Canada using a broader definition of productivity that included household work. Another objective is to identify and compare the factors related to the participation of household work of older adults in both countries. In order to conduct a comparative culture study two data sets were used; one was the 1999 Survey of Time Use collected by Korean Statistics Office and the other was 1998 Survey of Time Use collected by Canadian Statistics Office. Many countries have been collected a time use survey and used to study labor, welfare, and culture. Total number of 17,730 Korean and 2,729 Canadian between when and 84 were included to analyze the data. It is clear from the results that older people engage in productive behaviors, particularly when the definition of activities is broadened to include unpaid work. However, it is also clear the productive contributions in terms of household work ale lower among older Koreans than among older Canadians.

The main thrusts of Canadian regional innovation policy lies in the two tract system. Federal government decides only the strategic research and development sectors and priorities, and then researchers and stockholders in the regions decide and implement the specific networking relationships and appropriate governance system. This paper reviewed the decentralized and market-friendly Canadian regional innovation support system and the characteristics of Canadian innovation clusters: Learning, Labour, Location, Leadership, Legislation/ Labs. finally, policy implications for Korean regional innovation system such as networking, formation of social capital, and business support systems are offered.

The experiences and causes of pressure tube cracking accidents in the CANDU reactors and the development of the fuel channel at AECL(Atomic Energy Canada Limited) have been described. Most of the accidents were caused by Delayed Hydride Cracking(DHC). In the cases of the Pickering units 3&4 and the Bruce unit 2, excessive residual stresses induced by an improper rolled joint process played a role in DHC. In the Pickering unit 2, cracks formed by contact between the pressure and calandria tubes due to the movement of the garter spring were the direct cause of the failure. To extend the life of a fuel channel, several R&D programs examining each component of the fuel channel have been carried out in Canada. For a pressure tube, the main concern is focused on changing the fabrication processes, e.g., increasing cold working rate, conducting intermediate annealing and adding a third element like Fe, V, and Cr to the tube material. In addition to them, chromium plating on the end fitting and increasing wall thickness at both ends of the calandria tube are considered. There has also been much interest in the improvement of fuel channel performance in our country and several development programs are currently under way.

This study investigates the possibility of coupling empirical mode decomposition (EMD) for runoff prediction from machine learning (ML) models. Here, support vector regression (SVR) and convolutional neural network (CNN) were considered for ML algorithms. Precipitation (P), minimum temperature (Tmin), maximum temperature (Tmax) and their intrinsic mode functions (IMF) values were used for input variables at a monthly scale from Jan. 1973 to Dec. 2020 in the Grand river basin, Canada. The support vector machine-recursive feature elimination (SVM-RFE) technique was applied for finding the best combination of predictors among input variables. The results show that the proposed method outperformed the individual performance of SVR and CNN during the training and testing periods in the study area. According to the correlation coefficient (R), the EMD-SVR model outperformed the EMD-CNN model in both training and testing even though the CNN indicated a better performance than the SVR before using IMF values. The EMD-SVR model showed higher improvement in R value (38.7%) than that from the EMD-CNN model (7.1%). It should be noted that the coupled models of EMD-SVR and EMD-CNN represented much higher accuracy in runoff prediction with respect to the considered evaluation indicators, including root mean square error (RMSE) and R values.

Reservoir Characterization (RC) using 3-D seismic attributes analysis can provide properties of the oil sand reservoirs, beyond seismic resolution. For example, distributions and temporal bed thicknesses of reservoirs could be characterized by Spectral Decomposition (SD) and additional seismic attributes such as wavelet classification. To extract physical properties of the reservoirs, we applied 3-D seismic attributes analysis to the oil sand reservoirs in McMurray formation, in BlackGold Oilsands Lease, Alberta Canada. Because of high viscosity of the bitumen, Enhanced Oil Recovery (EOR) technology will be necessarily applied to produce the bitumen in a steam chamber generated by Steam Assisted Gravity Drainage (SAGD). To optimize the application of SAGD, it is critical to identify the distributions and thicknesses of the channel sand reservoirs and shale barriers in the promising areas. By 3-D seismic attributes analysis, we could understand the expected paleo-channel and characteristics of the reservoirs. However, further seismic analysis (e.g., elastic impedance inversion and AVO inversion) as well as geological interpretations are still required to improve the resolution and quality of RC.

Software education is inevitable for the success of the Fourth Industrial Revolution, and university education also requires innovation to cope with revolutionary change of the society. The number of students seeking employment in the IT field is steadily increasing regardless of the major of the student. However, the existing software-related courses offered by universities or private educational institutions are limited. This paper analyzes the existing software curriculum of several major universities for non-IT major students. In addition, in-depth surveys by students at Seoul Theological University is conducted to figure out the demand for the advanced level computer science subjects. Finally, new software education curriculum is proposed to fulfill the needs of non-IT major students and to improve the employment rate of non-IT major students seeking tech companies. The new curriculum will help to cultivate intermediate level IT experts that bridge the gap between advanced level IT experts and primitive level computer technicians.

The corporate restructuring following the economic crisis in Korea has brought about fundamental changes in the structure and practice of employment relations. However the lack of information on processes and consequences of such changes hider the appropriate policy making on shopfloor industrial relations. Correct assessment of realities and effective policy making require information on human resource management practices and structure of employment relations at the workplace level. This paper critically examines the experiences of workplace-employee integrated surveys carried out in advanced countries including Australia, Canada, and Britain, to extract methodological implications for such survey in Korea. We focus on the backgrounds of the surveys and practical issues involved in multi-level, longitudinal survey design.

The process of drug development has seen major changes over the last two decades with the movement away from standard small molecule drug discovery programs, through computer-assisted drug design methodologies towards biotechnologically derived products. The aim of duplication of endogenously active materials to be administered exogenously has enormous impact on development practices and evaluation of safety.(omitted)
