The recent Great Recession of 2008 was a period of sharp economic decline throughout the late 2000s. All socio-demographic groups were impacted by the economic downturn, however, Hispanic households were particularly hard hit. It is not a recent phenomenon that minority groups often have greater problems related to credit and debt repayments. A better understanding of these racial/ethnic differences in credit and debt has been hindered by the propensity of many studies to pool all racial/ethnic minorities together and compare them to white households. Using a Heckman-type selection model with a combination of the 2010 and 2013 Survey of Consumer Finances datasets to study household debt repayment problems, we found that racial/ethnic groups have been differently impacted by the recent Great Recession in terms of debt repayment problems. Hispanic households were less likely to hold debt; however, those with debt were just as likely as white households and African American households to be delinquent in repayments. This finding is contrary to prior research that indicated Hispanics with debt were less likely than white and African American households to be delinquent on repayments prior to the Great Recession of 2008. We propose possible explanations for the increase in debt repayment problems, that includes increased assimilation into the U.S. culture of credit use, the circumstance of being more recent home buyers prior to the decline, and living in states that suffered the greatest decline in housing value.

Korea has made the rapid economical development under the condition with the high population density and low available land. In this context, conservation of land environment, connected directly with living quality of human, has mostly ignored. Prior Environment Review System(PERS) is the one to investigate the locational validity, environmental impacts, harmony with surrounding environment, from the early stage of administrative plan or development project. PERS was amended to include SEA(Strategic Environment Assessment) system on June 1, 2006. But, several problems, including the loss of administrative ability, cost, and time, have been appeared, since the system is applied to all administrative plans without any distinction and plans or projects are delayed generally. In this study, the weaknesses of PERS were indicated through the comprehensive analysis including literature survey, study of legal and internet database, and the recently published PERS reports. Based on that, the improvement schemes were suggested to be harmonized with the nature of SEA. This study was mainly focused on a PERS for the designation of conservational area of hot-spring wells, conducted by authors.

Purpose - Work stress environment is expanding alongside the speed of worldwide change and psychological well-being concerns are coming about because pressure over-burden can bring about lost workdays, lower representative usefulness, and high occupation turnover rates. For this reason, this study investigates to provide how practitioners can manage employee work stress using health psychology based on prior studies. Research design, Data, and methodology - Qualitative textual research involves collecting and analyzing various non-numeric data to establish different concepts or opinions in prior literature. That means that the present researcher carried out qualitative research in multiple ways, investigating many kinds of previous textual data, such as prior published peer-reviewed resources and case studies analysis. Result - The results revealed that directed symbolism has been displayed to improve prosperity and tranquility among employees with an assortment of persistent infections. Like diaphragmatic breathing, reflection practices consolidate zeroing in on a particular article or sensation (like breathing) while at the same time separating from other distracters and controlling inward encounters (for example, feelings, musings) through non-critical acknowledgment. Conclusion - This research proposes that intellectual rebuilding or figuring out how to perceive maladaptive musings and change them to reflect more versatile; judicious idea examples can fundamentally further develop temperament, diminish pressure, and reduction negative feelings for employees.

Technology acceptance is one of the most popular research areas. Rapid developments in technology are making human life more comfortable. However, still most of the rural area has been deprived of benefits of technological advancement. Seventy percent population of India resides in rural area. Leveraging the improved penetration of the internet; mobile friendly population in rural India has been increasingly shopping online in the last few years. e-Governance is one of the important vehicles to provide efficient services to the citizens by Governments. One major obstacle is acceptance of e-Governance platforms by the citizens. Considering the increasing trend of using e-Commerce in rural area, this paper attempts to investigate moderating effect of online shopping experience on intention to use e-Governance portals. We surveyed 365 villagers across Maharashtra: one of the leading states in India. The result confirmed online shopping experience moderates the relationship between: 'perceived security & privacy' and 'attitude'; 'perceived security & privacy' and 'intention to use'; 'Perceived usefulness' and 'attitude'; and, 'attitude' and 'intention to use'. In this study definition of moderating variable 'experience' is unique and different than most of the popular studies. We defined experience as: 'prior use of any application of technology similar to the target application of technology'. Whereas prior studies considered experience as prior experience with target application of the technology.

This study is pursuited to construct the reasonable forecasting model through the combining AHP with ANP. It may be considered to be advanced study for prior various combining forecasts methods. Although prior studies are constrained to single or two criteria in selecting the optimal forecasting method, this study extend it to multi-criteria, inner and outer-dependence of clusters and elements, and feedback effect in hierarchy. A brief illustration is provided, and limitations of this study are presented.

As the era of the Fourth Industrial Revolution arrives and the culture of contact-less was established due to the long-term COVID-19, the construction industry is striving to develop smart home services to expand the scope of information and communications technology (ICT) to provide convenience to residents. However, various defects are occurring in information and communications technology facilities in apartments, and related research is lacking. In this study, case studies and research methods of related prior studies are analyzed as a basis for identifying the types and causes of defects that occur in information and communications technology facilities. To analyze various studies, we divided them into studies on smart home Internet of Things (IoT), information and communications technology construction of apartments, and investigated their features and limitations. Plus, future research will be conducted on apartments within 10 years of completion among apartments completed by domestic construction companies to supplement the limitations of prior research. In addition, we will prepare basic data on defects of ICT construction by analyzing the major causes of defect types through the analysis of defect types and frequency by detailed work type of information and communications technology construction.

We review the literature on the effectiveness of capital controls and macroprudential measures. First, we explain the purposes and examples of capital controls and macroprudential policies. We then analyze various theoretical models and empirical findings from prior studies that investigate the effectiveness of each instrument. Moreover, we review several studies that directly compare the two instruments and discuss whether policymakers should implement capital controls or macroprudential measures to overcome financial crises. Finally, based on a discussion of the findings of previous studies, we suggest several possible avenues for future research.

The horseshoe prior is notably one of the most popular priors in sparse regression models, where only a small fraction of coefficients are nonzero. The parameter space of the horseshoe prior is much smaller than that of the spike and slab prior, so it enables us to efficiently explore the parameter space even in high-dimensions. However, on the other hand, the horseshoe prior has a high computational cost for each iteration in the Gibbs sampler. To overcome this issue, various MCMC algorithms for the horseshoe prior have been proposed to reduce the computational burden. Especially, Johndrow et al. (2020) recently proposes an approximate algorithm that can significantly improve the mixing and speed of the MCMC algorithm. In this paper, we compare (1) the traditional MCMC algorithm, (2) the approximate MCMC algorithm proposed by Johndrow et al. (2020) and (3) its variant in terms of computing times, estimation and variable selection performance. For the variable selection, we adopt the sequential clustering-based method suggested by Li and Pati (2017). Practical performances of the MCMC methods are demonstrated via numerical studies.

This research investigated the opinions of teachers and directors on the integration of early childhood education and childcare centers in Korea. Participants were 800 teachers and directors working with young children in kindergartens and childcare centers. The survey consisted of questions regarding reasons, feasibility, and means of integration, as well as tasks that should be achieved prior to integration. Results showed that the participants were skeptical about executing the integration in practice even though they agreed to the integration of education and care in early childhood. They reported the integration of auspices should take place prior to integration of education and care in early childhood.

In this paper, we propose a new approach for recovering 3-D shape and extracting the reflectance properties of surface from intensity images. Photometric stereo method(PSM) is genrally based on the direct illumination. In this paper, the reflectance function is derived by interoduceing the indirect diffuse illumination in PSM and then applied to hybrid reflectance model which consists of two components; the lambertian and the specular reflectance. Under the hybrid reflectance model and the indirect diffuse illumination circumstance, the reflectance properties of sample surface can be extracting by normal sampler and then 3-D shape of an object can be recovered based on extracting reflectance properties. This method is rapid because of using the reference table and simplifies the restriction condition about the reflectance function existing in prior studies. Th erecovery efficiency in our method is better than that in prior studies. Also, this method is applied to various types of surfaces by defining general reflectance function.
