Sleep deficiency impacts the quality of life and may have serious health consequences in the long run. Questionnaire-based subjective assessment of sleep deficiency has many limitations. On the other hand, objective assessment of sleep deficiency is challenging. In this study, we propose a polysomnography-based mathematical model for computing baseline sleep deficiency severity score and then investigated the estimation of sleep deficiency severity using features available only from wearable sensor data including heart rate variability and single-channel electroen-cephalography for a dataset of 500 subjects. We used Monte-Carlo Feature Selection (MCFS) and inter-dependency discovery for selecting the best features and removing multi-collinearity. For developing the Regression model we investigated both the frequentist and the Bayesian ap-proaches. An Artificial Neural Network achieved the best performance of RMSE = 5.47 and an R-squared value of 0.67 for sleep deficiency severity estimation. The developed method is com-parable to conventional methods of Functional Outcome of Sleep Questionnaire and Epworth Sleepiness Scale for assessing the impact of sleep apnea on sleep deficiency. Moreover, the results pave the way for reliable and interpretable sleep deficiency severity estimation using a wearable device in Smart Health.

AbstractObjectiveRecent studies have indicated a lack of ENT training at the undergraduate and post-graduate levels. This study aimed to review the impact of recent educational innovations in improving ENT training for medical students and junior doctors in the UK.MethodsThree independent investigators conducted a literature search of published articles on ENT education. Included studies were analysed using qualitative synthesis methods.ResultsAn initial search yielded 2008 articles; 44 underwent full-text evaluation and 5 were included for final analysis. Most included studies demonstrated benefits for students when compared to existing teaching standards in terms of objective assessment (knowledge and skills gained) or subjective assessment (confidence and preference) following implemented educational innovations.ConclusionThis study identified educational innovations developed in the past 15 years to enhance the teaching of core ENT competencies. More research is needed to establish their impact on the state of ENT medical education in the UK.

The results of elaborations of available theoretical-analytical materials on measuring the quality of life are generalized, their orientation mainly on the assessment of the quality of life at the macro level for international comparisons is revealed. Methodical methods for assessing environmental safety as a component of quality of life at the level of administrative subregions of neighboring countries are substantiated and proposed: subjective assessment based on sociological research using questionnaires and objective assessment with a choice of representative, comparative, reliable assessment indicators, substantiation of their standards and calculations of environmental safety indices. The results are given of approbation of the proposed methods with coverage of subjective and obtained on the basis of quantitative indicators adapted to the system of official statistics of Ukraine and Poland objective assessments of the ecological component of quality of life in the studied cross-border subregions: Zhovkva, Sokal, Yavoriv districts of Lviv Oblast of Ukraine and Jaros?aw, Przemy?l, Lubacz?w Counties of the SubcarpathianVoivodeship of Poland. Significant disparities are identified not in favor of domestic subregions in the levels of environmental safety according to the results of objective assessment, which to some extent is smoothed in subjective assessment due to its dependence on the specific values and guidelines and environmental awareness of respondents. Conclusions are made on the complementarity of the results of subjective and objective environmental safety assessment, high value of the importance given by respondents to environmental safety as a component of quality of life, the impact of environmental safety asymmetry on the results of its subjective assessment, in particular, the priority of protection and preservation of certain components natural environment aimed at solving these problems.

The paper analyses the long-run (steady-state) output and price stability of a small, open economy which adopts a “crawling-peg” type of exchange-rate regime in the presence of various kinds of random shocks. Analytical and simulation results suggest that with the exception of money demand shocks, an exchange rate policy which involves a relatively higher rate of indexation of the exchange rate to price level is likely to lead to the worsening of price stability for all types of shocks. On the other hand, the impact of adopting such a policy on output stability depends on the type of the shock; for policy shocks to the exchange rate and shocks to output demand, output stability is worsened whereas for the shocks to risk premium of domestic assets, supply price of domestic output and the wage rate, better output stability is achieved in the long run.

This study analyses the impact of exchange rate and oil prices on the yield of sovereign bond and sukuk for Malaysian capital market. This study aims to ascertain the effect of weakening Malaysian Ringgit and declining of crude oil price on the fixed income investors in the emerging capital market. This study utilises daily time series data of Malaysian exchange rate, oil price and the yield of Malaysian sovereign bond and sukuk from year 2006 until 2015. The findings show that the weakening of exchange rate and oil prices contribute different impacts in the short and long run. In the short run, the exchange rate and oil prices does not have a direct relation with the yield of sovereign bond and sukuk. However, in the long run, the result reveals that there is a significant relationship between exchange rate and oil prices on the yield of sovereign bond and sukuk. It is evident that only a unidirectional causality relation is present between exchange rate and oil price towards selected yield of Malaysian sovereign bond and sukuk. This study provides numerical and empirical insights on issues relating to capital market that supports public authorities and private institutions on their decision and policymaking process.

Globalisation has had an unprecedented impact on the development and well-being of societies across the globe. Whilst the process has been lauded for bringing about greater trade specialisation and factor mobility many have also come to raise concerns on its impact in the distribution of resources. For South Africa in particular this has been somewhat of a contentious issue given the country's controversial past and idiosyncratic socio-economic structure. Since 1994 though, considerable progress towards its global integration has been made, however this has largely coincided with the establishment of, arguably, the highest levels of income inequality the world has ever seen. This all has raised several questions as to whether a more financially open and technologically integrated economy has induced greater within-country inequality (WCI). This study therefore has the objective to analyse the impact of the various dimensions of globalisation (economic, social and political) on inequality in South Africa. Secondary annual time series from 1990 to 2018 were used sourced from the World Bank Development indicators database, KOF Swiss Economic Institute and the World Inequality database. By using different measures of inequality (Palma ratios and distribution figures), the study employed two ARDL models to test the long-run relationships with the purpose to ensure the robustness of the results. Likewise, two error correction models (ECM) were used to analyse the short-run dynamics between the variables. As a means of identifying the casual effects between the variables, a Toda-Yamamoto granger causality analysis was utilised.

This study examines the impact of monetary and fiscal policies on the stock market in the United States (US), were used. By employing the method of Autoregressive Distributed Lags (ARDL) developed by Pesaran et al. (2001). Annual data from the Federal Reserve, World Bank, and International Monetary Fund, from 1986 to 2017 pertaining to the American economy, the results show that both policies play a significant role in the stock market. We find a significant positive effect of real Gross Domestic Product and the interest rate on the US stock market in the long run and significant negative relationship effect of Consumer Price Index (CPI) and broad money on the US stock market both in the short run and long run. On the other hand, this study only could support the significant positive impact of tax revenue and significant negative impact of real effective exchange rate on the US stock market in the short run while in the long run are insignificant.

Until now the government and private sector have not been able to address the backlog of 13.5 million housing units for ownership status and 7.6 million units for residential status. The high price of land has led to the high price of the house so that low-income communities (MBR) is not able to reach out to make a home purchase. In addition to the high price of land, tax factors also contribute to the high price of the house. The government plans to issue a policy for the provision of tax incentives, ie abolish VAT on home-forming material transaction. This policy is expected to house prices become cheaper, so the demand for housing increases, and encourage the relevant sectors to intensify its role in the construction of houses. It is expected to replace the lost tax potential and increase incomes. Analysis of the impact of tax incentives housing to potential state revenue and an increase in people's income, especially in Papua province is using the table IO because in addition to looking at the role each sector can also see the impact on taxes (income tax 21 Pph 25 Pph, VAT), and incomes (wage). Although in the short-term impact is still small, but very rewarding in the long run. Keywords: Backlog, Gross Input, Primary Input, Intermediate Input

<bold>Introduction:</bold> Perceived Health is a subjective assessment of the physical as well as mental health and includes so many aspects as mentioned in SF-36 form that are difficult to capture clinically such as incipient disease, physiological, psychological reserves and social functions. To assess the impact of Diabetes Mellitus, Hypertension and other socio-demographic factors on the Social Functioning component of mental health of the patients attending a tertiary care hospital in Bareilly. <bold>Material and Methods:</bold> Perceived health status of the patients was assessed by the Social Functioning dimension of the Mental Component Summary (MCS) using the SF-36 form. <bold>Results:</bold> The presence of both Diabetes Mellitus and Hypertension was associated with lower Social Functioning scores compared to those with diabetes (p = 0.013) and hypertension alone. Age was negatively related with Social Functioning scores (p<0.001) but male gender (p>0.000) and higher income (p<0.424) were all associated with higher Social Functioning scores. Rural subjects were found to have better SF score compared to urban. <bold>Conclusion:</bold> Age, gender and morbidity was found to have profound influence on Social Functioning scoring of the subjects. However, the results should be interpreted in terms of the study’s limitations.

The aim of this study is to examine the empirical cointegration, long-run and short-run dynamics and causal relationships between carbon emissions, energy consumption and economic growth in 14 Danube region countries over the period of 1990–2019. The autoregressive distributed lag (ARDL) bounds testing methodology was applied for each of the examined variables as a dependent variable. Limited by the length of the time series, we excluded two countries from the analysis and obtained valid results for the others for 26 of 36 ARDL models. The ARDL bounds reliably confirmed long-run cointegration between carbon emissions, energy consumption and economic growth in Austria, Czechia, Slovakia, and Slovenia. Economic growth and energy consumption have a significant impact on carbon emissions in the long-run in all of these four countries; in the short-run, the impact of economic growth is significant in Austria. Likewise, when examining cointegration between energy consumption, carbon emissions, and economic growth in the short-run, a significant contribution of CO2 emissions on energy consumptions for seven countries was found as a result of nine valid models. The results contribute to the information base essential for making responsible and informed decisions by policymakers and other stakeholders in individual countries. Moreover, they can serve as a platform for mutual cooperation and cohesion among countries in this region.

To cope with climate change and achieve sustainable development, low-carbon city pilot policies have been implemented. An objective assessment of the performance of these policies facilitates not only the implementation of relevant work in pilot areas, but also the further promotion of these policies. This study uses A-share listed enterprises from 2005 to 2019 and creates a multi-period difference-in-differences model to explore the impact of low-carbon city pilot policies on corporate green technology innovation from multiple dimensions. Results show that (1) low-carbon city pilot policies stimulates the green technological innovation of enterprises as manifested in their application of green invention patents; (2) the introduction of pilot policies is highly conducive to green technological innovation in eastern cities and enterprises in high-carbon emission industries; and (3) tax incentives and government subsidies are important fiscal and taxation tools that play the role of pilot policies in low-carbon cities. By alleviating corporate financing constraints, these policies effectively promote the green technological innovation of enterprises. This study expands the research on the performance of low-carbon city pilot policies and provides data support for a follow-up implementation and promotion of policies from the micro perspective at the enterprise level.
