Data Augmentation For Sorani Kurdish News Headline Classification Using Back-Translation And Deep Learning Model
Authors: Badawi Soran
Published: July 2023

With the increase in the volume of news articles and headlines being generated, it is becoming more difficult for individuals to keep up with the latest developments and find relevant news articles in the Kurdish language. To address this issue, this paper proposes a novel data augmentation approach for improving the performance of Kurdish news headline classification using back-translation and a proposed deep learning Bidirectional Long Short-Term Memory (BiLSTM) model. The approach involves generating synthetic training data by translating Kurdish headlines into a target language in this context English language and back-translating them to the Kurdish language, resulting in an augmented dataset. The proposed BiLSTM model is trained on the augmented data and compared with baseline models SVM (Support-Vector-Machines) and Naïve Bayes an trained on the original data. The experimental results demonstrate that the proposed BiLSTM model outperforms the baseline model and other existing models, achieving state-of-the-art performance on the Kurdish news headline classification task. The findings suggest that the combination of back-translation and a proposed BiLSTM model is a promising approach for data augmentation in low-resource languages, contributing to the advancement of natural language processing in under-resourced languages. Moreover, having a Kurdish news headline classification model can improve access to news and information for Kurdish speakers. With the classification model, they can easily and quickly search for news articles that interest them based on their preferred categories, such as politics, sports, or entertainment.

Published: July 2023

The national network of integrated continuing care is one of the most recent responses of the Portuguese National Health System. It is therefore crucial to carry out studies that assess this response, but also focus on the professionals who ensure the provision of care on a daily basis. Knowledge about work engagement of professionals is essential to improve the quality of these organizations. Work Engagement is an indicator of the relationship between the professionals and the work environment and is an important factor in performance and productivity. The aim of this study was to evaluate levels of engagement among these professionals. The data collection instrument consisted of a sociodemographic and professional questionnaire, and the Utrecht Work Engagement Scale short version (UWES-9) by Schaufeli and Bakker (2003), translated and adapted for the Portuguese population by Sinval et al. (2018). In a universe of about 1000 professionals from different units, 240 individuals were studied. The results obtained show that professionals have high work engagement values. There were statistically significant differences in the means of work engagement, taking into account the sociodemographic variables, marital status (F=-4.28; p=0.006) and age group (F=3.476; p=0.009) and socio-professional, classification in the remuneration (t=-5.015; p<0.001), professional experience (t=-3.343; p<0.001) and professional category (F=6.385; p=0.002). Regression analyses that showed a R square determination coefficient value, obtained, 12,4% of the variance in work engagement can be explained by the demographic and job features variables.

For selected cases, both primary energy use and CO2 emission have been compared.
Sets of factors influencing the subsystem objective function of a heater and its efficiency in central water heating systems
Authors:   Life Member ASHRAE, Šiljak Mile
Published: July 2023

Due to current world problems existing in space and time as never before, with pronounced ongoing degradation tendencies, the energy efficiency of singular, partial and/or integral energetically active units in the domain of applied thermotechnics in buildings is gaining excessive importance which, as an imperative, obligates the industry to carry out, within the limits of feasibility, sophisticated professional observations to prevent their degradation during the working life. Among the numerous central heating systems, "central water heating systems" are certainly the most common and have the longest application tradition. In the general structural arrangement of these systems at the level of subsystems, there is a recognizable, defined subsystem of equal importance for "releasing heat to the heated space with accompanying fittings." The subsystem objective function is influenced by numerous sets of influencing factors, which can significantly affect the subsystem and integral quality of the implemented system and its efficiency during its intended use. As an active analyst in the field of central heating systems, I approached this research for deontological reasons and intending to improve theory and practice in this field, but also to eliminate any possible errors, doubts, misconceptions, illusions, frauds and/or adverse consequences in the achievement of "energy efficiency" of the defined subsystem. In principle, the following sets of influencing factors have been identified: a set of geometric factors; a set of fluid factors; a set of correlation factors; a set of transmission factors; a set of interior factors; a set of cultural factors; and a set of psycho-physiological factors. The findings indicate, among other things, that accepted partial subsystem units, i.e., the subsystem for "releasing heat to the heated space with accompanying fittings" in the phase of the intended use of the object concerned, has a pronounced impact on the subsystem and integral system energy efficiency.

In this paper, the impact of the presence of surrounding buildings on the energy behavior of a non-residential building for climatic conditions in Serbia was examined. For the first time, this impact was considered for different people occupancy schedules, real, average yearly and maximum occupancy, and two different ventilation methods (Method 1 and 3), defined according to the currently valid standard EN 16798. The findings of this study indicate that the predicted total heating energy demands of a building may be significantly affected due to the shading caused by adjacent objects. Through building energy simulations, it was found that a building with a shading effect consumes from 6.43% to 11% more energy than a building where the presence of surrounding buildings is neglected. Neglecting this impact leads to an error in predicting the building's energy consumption. Observing the simultaneous impact of the people occupancy and surrounding objects, this error can reach a value of as much as 21.13%. Based on the presented results, in order to bring the predicted energy behavior of the building closer to its actual behavior, it is recommended to use the real occupancy schedule. The maximum occupancy schedule, in any case, should be avoided. For the same reason, the adjacent shading effect needs to be accounted for in building energy simulation studies. This effect should be also taken into consideration when planning and developing a new urban settlements.

Published: July 2023

Building energy performance prediction is very important since allows engineers to evaluate, among others, system operation energy consumption and costs. Many different methods exist for performance prediction, from simple to very complex, but choosing an appropriate method is as important as using methods regularly. In this paper, estimation of energy consumption and costs with BIN method was performed for refurbishing air conditioning system in office building in Belgrade. The proposed heat recovery from exhaust air by installing a heat pump system between exhaust and fresh air had been compared to existing system and has shown great cost reduction for air preparation of nearly 85%. The methodology applied is not computationally intensive and can be done regularly for heat pump systems with air as a heat source if proper weather data for location are provided and generated. In addition, one way to generate necessary BIN data from regularly available typical meteorogical year was shown.
Analysis of resource potential of objects of oil-contaminated wastes recycling system with variable scale effect
Authors: Derevyanov Maxim Yurjevich
Published: July 2023

The article proposes a new approach developed according to the Data Envelopment Analysis (DEA) method for calculating the estimates of the resource potential of the schemes of oil-contaminated waste (OCW) storage - recycling technology as part of the OCW recycling system. A two-stage calculation algorithm has been developed, at the first stage of which the estimate of the resource value of the OCW in storages is calculated in a known way, and at the second stage, using the BCC and Super-efficiency models of the DEA method, estimates of the resource potential of system objects with a constant, decreasing or increasing effect of scale are determined. Depending on the ranking of the obtained estimates of the resource potential of the objects of comparison in the system and the effect of scale, the order of processing of the OCW in storages by the appropriate technologies is determined. The developed procedure for control waste recycling in the system allows making sound operational and tactical decisions based on the results of solving two optimization problems according to the criteria: increasing the resource potential of the system objects and reducing the processing time. Approbation of the developed approach was carried out on the example of the OCW recycling system, which includes 20 storage facilities and 10 technologies located on the territory of the Samara region. The proposed approach can be extended to other regions of the Russian Federation to make informed management decisions in the OCW recycling system.

Published: July 2023

Obesity is excessive body fat and was associated with the importance of metabolic and endocrine problems in somatotropic secretion in functional obesity. Ghrelin is an acylated peptide hormone produced by the stomach, which is a mediator of the growth hormone secretory receptor. The activity of ghrelin stimulates the release of growth hormone, and appetite and stimulates the metabolism of carbohydrates. Circulating ghrelin levels in healthy people increase during fasting and decrease after meals. This study aims to analyze the difference in ghrelin levels among obese and non-obese subjects. A cross-sectional design research was conducted in August 2022. The samples consisted of obese and non-obese subjects based on Body Mass Index (BMI). Ghrelin levels were measured using the Enzyme-Linked Immunosorbent Assay (ELISA) method. The data were statistically analyzed using the Mann-Whitney and Spearman tests. p<0.05 was reported significant. The samples consisted of 80 obese and non-obese subjects, 39 males and 41 females. There was no difference in ghrelin serum levels in the obese group (1.45±2 ng/mL) compared to the non-obese group (0.67±0.25 ng/mL) with p =0.233 (p>0.05). There was a positive correlation between ghrelin levels and BMI (r=0.247). There was no difference in ghrelin levels between the obese group and the non-obese group, and there was a positive correlation between ghrelin levels and BMI. A higher BMI would lead to higher ghrelin levels.

Bifunctional DNA glycosylases employ an active site lysine or the N-terminus to form a Schiff base with the abasic site base excision repair intermediate. For the 8-oxoguanine DNA glycosylase 1 (OGG1), cleaving this reversible structure is the rate-determining step in the initiation of 8-oxoguanine (8-oxoG) repair in DNA. Evolution has led OGG1 to use a product assisted catalysis approach, where the excised 8-oxoG acts as a Brønsted base for cleavage of a Schiff base intermediate. However, the physicochemical properties of 8-oxoG significantly limit the inherent enzymatic turnover. We hypothesized that chemical synthesis of purine analogues enables access to complex structures that are suitable as product-like catalysts. Here, the nucleobase landscape is profiled for its potential to increase OGG1 Schiff base cleavage. 8-Substituted 6-thioguanines emerge as potent scaffolds enabling OGG1 to cleave abasic sites opposite any canonical nucleobase by β-elimination. This effectively broadens the enzymatic substrate scope of OGG1, shaping a complete, artificial AP-lyase function. In addition, a second class of activators, 6-substituted pyrazolo-[3,4-d]-pyrimidines, stimulate OGG1 function at high pH, while thioguanines govern enzymatic control at acidic pH. This enables up to 20-fold increased enzyme turnover and a de novo OGG1 β- elimination in conditions commonly not tolerated. This allows for the development of activators applicable in distinct pH environments of different cellular compartments.
Machine learning-based prediction of activation energies for chemical reactions on metal surfaces
Authors: Hutton Daniel J. , Cordes Kari E. , Michel Carine , Göltl Florian
Published: July 2023

In computational surface catalysis, the calculation of activation energies of chemical reactions is expensive, which in many cases limits our ability to understand complex reaction networks. Here, we present a universal, machine learning-based approach for the prediction of activation energies for reactions of C, O, and H containing molecules on transition metal surfaces. We rely on generalized Bronsted-Evans-Polanyi relationships in combination with machine learning-based multiparameter regression techniques to train our model for reactions included in the University of Arizona Reaction database. In our best approach, we find a Mean Absolute Error for activation energies within our test set of 0.14 eV if the reaction energy is known and 0.19 eV if the reaction energy is unknown. We expect that this methodology will often replace the explicit calculation of activation energies within surface catalysis when exploring large reaction networks or screening catalysts for desirable properties in the future.

Background

Antibody-based serological tests which target households and communities can estimate the true extent of infection in a population. It minimizes the biases of facility-based selective testing and generates scientific data on disease transmission through household asymptomatic cases. The objective of this study was to determine the seroprevalence and trend of SARS-CoV-2 in a densely populated urban community of Karachi.

Methods

Three serial cross-sectional surveys were conducted in November 2020, February 2021, and December 2021 in Karachi’s District East. Households were selected to provide serum samples for Elecsys® immunoassay for the detection of SARS-CoV-2 antibodies. All household members were eligible to participate regardless of age and infection status. Bayesian regression was used to adjust for assay performance and estimate seroprevalence.

Results

We enrolled 1506 participants from 501 households. In November 2020, adjusted seroprevalence was estimated as 24.0% (95% confidence interval, CI=18.0-31.0), compared to 53.9% (95% CI=45.5-63.2) in February. In December 2021, it increased to 84.9% (95% CI=78.5-92.3). The conditional risk of infection was 41% (95% CI=29.9-51.6), 56.7% (95% CI=50.4–62.6) and 77.8% (95% CI=73.0-81.7) in surveys 4, 5, and 6 respectively. Only 18.7% of participants who had reactive antibodies for COVID-19 were symptomatic.

Conclusions

An increase in seroprevalence estimates in Karachi’s District East was observed over time. Community-based seroprevalence studies help to estimate the true proportion of the population that has been infected and predicts the spread of the disease in similar settings.
MOBILIZING THE MUSLIMS: OTTOMAN-GERMAN PROPAGANDA IN WORLD WAR I
Authors: UÇAN Ceren
Published: July 2023

On 2 August 1914, the Ottoman Empire and the German Empire agreed on an alliance, and the Ottoman Empire officially entered into World War I on 29 October 1914 as one of the Central Powers. In November, jihad was proclaimed by the Ottoman Sultan. The Ottoman and German governments published pamphlets, leaflets, and newspapers to mobilize Muslims in India, Egypt, and other dependencies of the Allies. They aimed to incite mutiny among native populations in their armies, foster Pan-Islamism, or create pro- German sentiments. While some of the propaganda materials invited Muslims to holy war, others used the Caliphate and the Ottoman Empire as a bridge to reach the Muslims. This article examines German and Ottoman propaganda to mobilize Muslims against the Allies.

The Making of White Porcelain Incense Burner in Early Chosŏn and their Uses in Royal Ceremonies
Authors: Shin Hyegyeong
Published: July 2023

This study focuses on white porcelain incense burners used for royal ancestral rites in Chosŏn. Starting from early examples of Confucian incense burners, I have examined their production process and characteristics. As incense burning was an essential part of Confucian rites, incense burners also became important vessels. The earliest examples are found at Pŏnch’ŏn-ri site No. 21, dated to 1420-40, and they likely resemble the prototypes of ceremonial incense burners made of metal. Incense burners were influenced by the changes in the Chosŏn society and incense burning methods, and they took the shape of ding with cover. This testifies to the effort made to prepare suitable burners for Confucian rituals. Surviving records state that incense burners were to convey the simple and rustic beauty of the earth, and to work as simple so-gi, which were likely the reasons for making incense burners in white porcelain. It is also noteworthy that early Chosŏn style and uses continued to influence those of the mid-and late Chosŏn. In conclusion, the material of white porcelain and the shape of incense burners were chosen according to their uses, and they developed independently of metalware, not as mere substitutes.

The majority of MSMEs in the Sukmajaya sub-district, Depok, are engaged in the culinary field, totaling 771 MSMEs out of a total of 2,835 MSMEs. The decline in the number of MSMEs in 2020 due to the Covid-19 pandemic has made it difficult for MSMEs to market their products. On the other hand, during this period, SMEs emerged with digital innovation. Digital marketing planning is necessary for MSMEs in running their business to create a competitive advantage and improve marketing performance. MSMEs that do not implement digital marketing in running their business will be left behind and lose customers because customer buying behavior has changed towards digital.

This research is quantitative descriptive research using the SmartPLS 3.0 tool to analyze the effect of each variable. The type of data is primary data by distributing questionnaires to 125 Culinary MSME respondents in the Sukmajaya sub-district, Depok city via Google form. In this study, data analysis techniques were carried out in the form of descriptive data analysis and inferential data analysis, and hypothesis testing.

The results of the study prove that digital marketing planning using the SOSTAC method has a positive and significant effect on Competitive advantage, SOSTAC Digital marketing planning has a positive and significant effect on marketing performance and Competitive advantage has a positive and significant effect on marketing performance. The results of the study show that SOSTAC Digital Marketing Planning has a positive and significant indirect relationship to marketing performance through competitive advantage, which is bigger than the direct relationship. Thus, in SOSTAC Digital Marketing Planning, to achieve marketing performance, MSME actors must first be able to create a competitive advantage.
Financing of state-owned entities: Can the Trade-off Theory explain the debt structure?
Authors: Abbana Sharanam , Marimuthu Ferina
Published: July 2023

The purpose of this research is to determine if the financing behaviour of South African state-owned entities (SOEs) have a target capital structure which they adjust towards and if so, the speed of adjustment, a central tenet of the Trade-off Theory. An unbalanced panel data set from a sample of thirty-three commercial SOEs were studied using a dynamic partial adjustment model. The findings provide strong evidence that South African SOEs follow the trade-off theory based on the existence of a target capital structure and speed of adjustment of 21.5% per annum towards the target which is slower than other SOEs in developing economies. The findings also revealed that these SOEs take almost five years to close off two-thirds of the gap between the actual and optimal capital structures. The findings will be of interest to observers of the economy, as they measure the capacity of SOEs to play a leading role in investment and in improving the efficiency of the economy. They could also inform decision making and policy development on SOEs.

Published: July 2023

The global outbreak and spread of coronavirus disease (COVID-19) have been referred to as the most dangerous pandemic since World War II. The speed of the spread and the severity of the damage caused by the virus has traumatized the global economy affecting both banks and customers. With the lockdown imposed by the government to restrict the movement of people and activities caused by the increased level of coronavirus cases in Nigeria, the fate of the financial users of about 40 million became unknown. Given the analysis of data on trends of COVID-19 infections from the World Health Organization and Nigerian Centres for Disease Control and Prevention, the study assessed the current situation. It indicated some specific concepts that the banking sector should consider and address while taking the necessary measures to cope with the new change. The study used an ex-post-facto research design, enabling the researcher to measure the effect or relationship between the dependent variable and explanatory variables using time-series secondary data. The data collected was reviewed, and validated by CBN, the Nigeria Bureau of Statistics, and the Nigerian Inter-Bank Settlement System (NIBSS) websites. The study concluded that the ICT volume of e-payment has no significant effect on operational efficiency in Nigeria Banks, and the ICT value of e-payment significantly affects operational efficiency in Nigeria Banks during the coronavirus lockdown.

Objectives:Moral distress has been identified as both a contributor to healthcare worker attrition as well as an outcome of it. To this aim, our study applies intersectional analysis to explore moral distress levels among doctors, nurses, and in-home- or community-care-providers in British Columbia, Canada with a specific focus on the intersection of race and gender identity. Furthermore, it aims to identify which experiences were more distressing, and the predicted turnover intent for each intersecting identity and profession.Methods:We conducted an online survey of 1,314 healthcare professionals from all health regions of BC. Our descriptive analysis was stratified by the participants’ profession. The categorical variables included age, gender, racial identity, migratory history, and type of work contract. The continuous variables included a moral distress score (range: 0 to 144) and a mitigation score consisting of 11 distress-coping strategies (range: 0 to 275).Results:Nurses had significantly higher moral distress scores compared to physicians and in-home- or community-care-practitioners (H-CCPs). Only 24.7% of physicians had considered leaving their position or had already left, compared to 61.3% of H-CCP, and 72.7% of nurses. White women had significantly higher moral distress levels than White and Indigenous men, whereas women of colour were more distressed than White men, though these differences were no longer significant after adjusting the scores by profession. Men had higher mitigation scores than women across all groups. Sources of distress and mitigation strategies differed across identity groups. White men had a significantly lower turnover intention (15.3%) than all other groups. Conclusion:High distress scores and turnover intention responses, particularly among women and racialized healthcare workers indicate an urgent need to address the root causes of moral distress.

Previous research demonstrated that cognitive reappraisal and distraction modulate pain. However, little is known about their differential effectiveness when the intensity of pain is low and moderate. The aim of this study was to analyse the differential efficacy of both strategies to reduce perceived pain intensity and pain unpleasantness under low and moderate pain levels. Ninety healthy adults completed the pain experimental procedure. Analyses of covariance (ANCOVA) showed that at post-test, cognitive reappraisal and distraction were equally effective in reducing perceived pain intensity scores under a low level of pain stimulation; however, distraction was superior to cognitive reappraisal in decreasing perceived pain intensity scores under moderate pain levels. Neither distraction nor cognitive reappraisal were effective in decreasing pain unpleasantness scores regardless of the intensity of the painful stimuli. These findings highlighted that cognitive reappraisal and distraction are useful in the short-term to reduce perceived pain intensity in acute pain.

Çalışmamızda 2006-2012 yılları arasında inşa edilen hükümet konakları ele alınmıştır. Hükümet konaklarının Osmanlı İmparatorluğu’ndan günümüze kadar Türk mimarlık tarihi çerçevesinde geçirdiği değişim ve gelişim ele alınarak tümevarım yöntemi ile günümüzdeki durum ortaya konulmaya çalışılmıştır. İç İşleri Bakanlığı verileri ana kaynak olarak kabul edilmiştir. 260 adet konağın bu boyutta bir çalışma için detaylı incelemesinin mümkün olmaması nedeni ile genel, tarihi, cephe özellikleri ve tipolojileri üzerinde toplu olarak durulmuştur. Konakların mimarlık dönemleri içerisinde meydana gelen üslup değişimlerinden etkilendiği görülmüştür. 2006-2017 tarihleri arasında inşa edilen konakların özellikle Osmanlı Geç Dönem ve I. Ulusal Mimarlık Dönemi kamu binalarından plan, cephe ve üslup bakımından etkilendiği görülmüştür. Ele alınan dönemin hükümet konakları açısından postmodern bir yaklaşımla inşa edildikleri düşünülmektedir.
