EU funds as a catalyst of change for the Slovak healthcare system?
Authors: Fidrmuc Jan , Gardoňová Kristína , Hulényi Martin , Sekelský Lukáš , Zlaczká Veronika
Published: January 2022

In the programming period 2007-2013, the European Structural and Investment Fund (ESIF) invested €237 million in Slovak hospitals. We investigate whether this injection of additional funds has improved the quality of healthcare in the targeted hospitals. As a measure of quality, we use the readmission rate (ratio of readmissions within 30 days over total hospitalizations) and the mortality rate. Our results show a statistically significant but small effect of ESIF on the readmission rate but not on the mortality rate. We argue that these results suggest that the main problem in Slovak healthcare is low productivity rather than lack of funding.

Published: January 2022

Psychological well-being is the condition of individuals who are able to assess themselves and others positively, be able to make decisions independently, and have clear life goals. Individuals who have good psychological well-being will feel happy and satisfied with the life they have. Psychological well-being is related to the individual’s personality, while the personality of each individual will be different in responding to self-adjustment and will appear different according to how the individual adjusts. Based on this, psychological well-being is influenced by self-adjustment. A man who is a father, husband, and head of family who can adjust well will have a harmonious and prosperous life in his marriage. This research applied a correlational quantitative method with an independent variable of self-adjustment and a dependent variable of psychological well-being. Data were collected using a psychological well-being scale and a self-adjustment scale. 100 fathers with an age range from 19 to 40 years were recruited through purposive sampling. Data were analyzed through the Pearson product-moment correlation test. The correlation coefficient value in this study was 0.601 with a p-value of 0.001 (p < 0.05). These findings showed that there was a significant positive relationship between self-adjustment and psychological well-being in fathers.

The roles and strategies of ASEAN in the Belt and Road Initiative (BRI)
Authors: Park Sang Chul
Published: January 2022

Under the Belt and Road Initiative (BRI), China focuses on the ASEAN as part of land bridge connecting China to Southeast Asia, the Indian Ocean, and the China-Indochina Peninsula Corridor sea route that is the comprehensive sea route between China, South China Sea, Indian Ocean, and Europe. On the other hand, ASEAN member nations regard the BRI as an avenue to improve connectivity with their poor infrastructure development which will generate trade and investment increase in the region particularly through improved logistics. Accordingly, ASEAN member nations are keen to develop their infrastructure projects in collaboration with Chinese companies and funding agencies mainly in the forms of joint venture. The Asian Development Bank (ADB) estimates that the total infrastructure investment needs in the ASEAN from 2016 to 2030 will be between USD 2.8 trillion with baseline estimate to USD 3.1 trillion with climate adjusted estimate. This paper aims to argue how China and the ASEAN can be interacted by the BRI and what are impacts of the BRI on the region. Furthermore, it analyzes which roles do the BRI play in building the region between China and the ASEAN member nations. Last, but not least, it also focuses on Chinese national strategy how to implement the BRI in the region.

Digital currencies: Challenges between the United States, the European Union and Asia Pacific
Authors: Ricoy-Casas Rosa María
Published: January 2022

In June 2019, Facebook announced its own cryptocurrency “Libra” to be used through WhatsApp and Messenger, in order for its value to remain stable thanks to the support from banks and electronic commerce companies, linking to different currencies and the support of important companies. EU antitrust regulators investigated it as a “threat to monetary sovereignty”. China is already testing its own DCEP cryptocurrency tied to state banks and major companies, with notable advantages. It will probably displace cash and be used even for world trade, which can make it an alternative to the traditional international payment system, compared to the current one led by the United States with the USD. The Belt and Road Initiative (BRI) offers “the area and the route” to extend the Yen as a global digital currency. These new developments, and their rapid and high competitiveness produced as the “art of bian lian”, have generated intense concerns in the international financial system. Will the EU, Japan or the US be able to counter the virtual yuan so quickly?

Ссылка для цитирования: Обзор современных технологий переработки упорных золотосодержащих руд и концентратов с применением азотной кислоты / Д.В. Гордеев, Г.В. Петров, А.В. Хасанов, О.В. Северинова // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2022. – Т. 333. – № 1. – С.214-224.

Актуальность. Упорность золотосодержащих руд обусловлена двумя факторами: первый заключается в тонкой диспергации золота в сульфидных минералах, второй – в наличии углеродистого вещества, ответственного за протекание процесса прег-роббинга, приводящего к неизбежному снижению извлечения золота. В современной золотоизвлекательной промышленности существует множество способов переработки упорного золота с содержанием углеродистого вещества до 1 %, однако более высокие его концентрации до сих пор вызывают большие проблемы. Одним из наиболее интересных и перспективных способов минимизации влияния углерода на извлечение золота является использование азотной кислоты, поскольку данный реагент может, с одной стороны, интенсифицировать процесс окисления или удаления углеродистого вещества, а с другой – запассивировать его поверхность и таким образом значительно снизить сорбционную активность углеродистого вещества. Актуальность данной работы обусловлена отсутствием в современной золотоизвлекательной промышленности технологии, позволяющей перерабатывать высокоуглеродистое сырье и перспективностью применения азотной кислоты в гидрометаллургии золота.  Цель работы заключалась в обосновании значимости применения азотной кислоты в технологии автоклавного окисления упорных золотосодержащих концентратов. Результаты. Проведен обзор современных методов переработки упорного золота, выявлены основные преимущества и недостатки каждого. Установлено, что ни один из методов не позволяет эффективно перерабатывать высокоуглеродистое сырье из-за невысокой степени оксиления/пассивации углеродистого вещества, которое ответственно за протекание процесса прег-роббинга. В работе представлены технологии переработки золотосодержащего сырья в азотнокислых средах, показано, что азотная кислота может использоваться не только как основной окислитель, но также и как катализатор химических реакций окисления и пассиватор поверхности углеродистого вещества. Описанные в работе уникальные свойства азотной кислоты могут быть успешно применены в автоклавной гидрометаллургии золота.

Актуальность. Сложная картина баланса Th и U, взаимосвязь их с редкоземельными элементами в природных водах различного состава и важность этих элементов как индикаторов для гидрогеохимических построений и выводов определяет актуальность их изучения в разных регионах с использованием современных аналитических методов. Цель: рассмотреть баланс тория и урана и взаимосвязи радиоактивных и редкоземельных элементов в природных водах центрального Сихотэ-Алиня (Приморский край). Объекты: содержание и баланс урана и тория в природных водах трех районов центрального Сихотэ-Алиня в Приморском крае: «Шандуй», «Ванчин», «Бикин». Методы. 55 элементов определены методом масс-спектрометрии с индуктивно связанной плазмой (ICP-MS) (спектрометр Agilent 7700х, Agilent Techn., США). Вторая пробирка использовалась для определения пяти макрокатионов атомно-эмиссионной спектрометрией (спектрометр iCAP 7600 Duo), а также шести анионов ионной хроматографией (ионно-жидкостный хроматограф LC-20, Shimadzu, Япония). Результаты. Приводятся новые данные по содержанию радиоактивных элементов (тория и урана), величине Th/U, содержанию РЗЭ в природных водах, приуроченных к расположению кудуров (специфических мест проявления литофагии) в трех районах, находящихся территориально в центральном Сихотэ-Алине Приморского края: «Шандуй», «Ванчин», «Бикин». Установлены средние содержания радиоактивных (Th, U) и редкоземельных (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) элементов в природных водах. Исследуемые природные воды относятся к ультрапресным и пресным, со средней минерализацией 52,4 мг/л. Содержание U в водах колеблется от 0,005 до 1,067 мкг/л. Концентрация Th в воде колеблется от 0,003 до 2,299 мкг/л. Соотношение торий–уран в водах колеблется от 0,01 до 5,3. Отмечается положительная зависимость между содержанием тория в водах и количеством редкоземельных элементов в пресных водах. Спектр распределения редкоземельных элементов в природных водах, вероятно, наследуется из дренируемых цеолитизированных и оглиненных кислых пород.

Математическая модель работы компрессора реализована на языке программирования Python. Результаты. Анализ влияния тепловых процессов на работу устьевого компрессора показал значимый эффект температуры окружающей среды на производительность компрессора. По результатам расчетов было установлено, что при низких температурах производительность компрессора выше, чем при высоких. Установка радиатора негативно сказалась на производительности компрессора, особенно при низких давлениях на приеме. Установка теплоизоляции напротив позволила несколько увеличить производительность компрессора, но не значительно. Основным фактором, влияющим на производительность компрессора, является давление на приеме (величина перепада давления), поэтому в начальный период работы компрессора, когда давление на приеме приближается к линейному давлению в трубопроводе, производительность компрессора высока.

Background: Moong bean (Vigna radiate L.) plays an important role in antioxidant, antimicrobial, antidiabetic, anti inflammatory, antihypertensive and antitumor effects. Mostly beans and legumes cause gas and abdominal bloating in some people but the moong beans are the easy to digest. Soaking the beans in water before cooking and also sprouting them reduces this issue. The high levels of amino acids, oligosaccharides and polyphenols provide high antioxidant levels not only fight tumors and cancer but also protect against DNA damage and cell mutation. The seed of moong bean acts as a nutraceutical because it provides beneficial effects on human health and also helps in the prevention of cardiovascular disease, diabetes, digestive tract diseases, overweight, obesity and cancer etc. The flavonoids vitexin and isovitexin have high free radical scavenging activities which help lower oxidative stress, the cancer causative factor. It is not only lower blood glucose levels, but also reduce total cholesterol levels, triglycerides, plasma C peptides and glucagon levels. Samples of moong bean were collected from Legume Section of the University. Methods: Through NIRS-2500 evaluated samples of moong bean. It is an instrument through which Near Infrared (NIR) analysis a spectroscopic technique that makes use of the naturally occurring electromagnetic spectrum. This works in the region of the spectrum defined by wavelengths between 700 nm and 2500 nm. All the cultivars were found to cluster in major four groups on the basis of principal component analysis. The result showed the diversity between nutritional and antinutritional factors in the cultivars that could be further used by plant breeders to develop superior genotypes. The moong bean has lots of advantages which cure the several diseases such as cardiovascular disease, type 2 diabetes, digestive diseases and some cancers. Result: Histidine amino acid was varied from 6.40% to 8.81%, arginine amino acid from 2.21% to 3.87%, valine amino acid from 2.92% to 4.44%, phenylalanine from 9.73% to 13.86%, isoleucine from 9.28% to 10.02%, methionine from 0.09% to 1.26%, leucine from 6.02% to 7.65%, tryptophan from 0.30% to 0.68%, lysine from 2.03% to 2.22% and threonine from 4.32% to 5.56%. The grain color have the direct related to carotenoids and polyphenols. The hardness of the grain is due to fiber amount of the grain. The moisture is related to the properties such as sphericity, porosity, bulk density. Mostly anti-nutrients factors such as phytic acid, tannins, hemagglutinins and polyphenols associated with the grain. The effects of storage and processing on nutrients and food processing properties are needed to enable optimization of processing steps, for better mung bean food quality and process efficiency.

The current use of thermal imaging has been documented in wild animals due to the benefit for having real-time results with less or almost no restrain or invasive methods required - and this is significant for better well-being. This paper will explore the thermal imaging studies as a part of employing non-invasive methods in evaluating physiological function, in particular with refinement of the methods, followed by further computational analysis of the images to ensure the validity of the methods as predictive tools for pregnancy diagnosis. We conducted refinements in thermal imaging methods and computational analysis of deep learning for pregnancy diagnosis of cynomolgus monkeys (Macaca fascicularis) at breeding facility of The Primate Research Center, LPPM IPB University. Subjects were already identified by ultrasound as pregnant in 80, 120 and 130 days. Thermal images along with the temperature data were obtained from FLIR ONE camera in sedated animals with dorso-ventral recumbence. The temperature data were analyzed with linear regression to correlate the skin temperature and the days of pregnancy to make a prediction of pregnancy days based on temperature data. There is a positive correlation of the temperature to the pregnancy days with a function of temperature to days. Further computational analysis of the thermal image, the results showed that the refined methods and the computational analysis brought better interpretation to evaluate health and reproductive status, in particular with the pregnancy diagnosis.
Meandering pulmonary vein: a variant of the "scimitar" syndrome

Published: January 2022

The paper presents a clinical case of a 38-year-old woman who had an anomalous confluence of the right pulmonary vein, both into the inferior vena cava and into the left atrium, which corresponds to be the "scimitar" syndrome. The abnormal pulmonary vein made several bends before draining into the left atrium, which is described in foreign literature as a "meandering pulmonary vein". To clarify the diagnosis, a CT scan of the chest with bolus contrast enhancement and a deep analysis of literature sources were performed.

Three Malay Theological (Aqida) Texts of the 19th Century and Issues Connected to Human Actions
Authors: Nasir Nasrin
Published: January 2022

This paper attempts to provide an archeology of knowledge more specifically the knowledge of faith as it is taught in contemporary Malaysia. Several texts have been identified to be taught in various madrasahs and at times local community prayer halls called “surau” in teaching credal belief to the religious students and public. A total of three main texts had been identified as being the most popular in the teaching of credal belief to the masses. Credal belief as it is sanctioned by the country’s religious establishment is the Asha’irah school which is part of the broad Ahlussunnah wal Jamaah belief system in Islam. The texts chosen are the popular texts used in teaching aqidah in the madrasah and mosques in the country. They are al-Durr al-Thamin (1232/1817), Aqidatun Najin fi ilmi usul al-Din (1308/1891) and Faridatul Fara’id (1313/1895). The relation between God and His creatures as depicted in the texts here would be exposed and analysed. Whether human actions are free or taking from the teachings of Ash’arite theologians, the idea of kasb is explained. This paper via a critical textual analysis aims to ask questions connected to issues of freewill while highlighting the role of God in human actions.
Mental Disorder Symptoms among Paramedics in a Single Canadian Site

Published: January 2022

There is growing recognition in research and policy of a mental health crisis among Canada’s paramedics but despite this, epidemiological surveillance of the problem is in its infancy. Just weeks before the emergence of the COVID-19 pandemic, we surveyed paramedics from a single, large, urban paramedic service in Ontario, Canada to assess for symptom clusters consistent with Post-Traumatic Stress Disorder (PTSD), major depressive disorder, and generalized anxiety disorder and to identify potential risk factors for each. In total, we received 589 completed surveys (a 97% completion rate) and found that 11% screened positive for PTSD, 15% for depression, and 15% for anxiety, with 1 in 4 active-duty paramedics screening positive for any of the three as recently as February 2020. In adjusted analyses, the risk of a positive screen varied as a function of employment classification, gender, self-reported resilience, and previous experience as a member of the service’s peer support team. Our findings support the position that paramedics screen positive for mental disorders at high rates – a problem likely to have worsened since the onset of the COVID-19 pandemic. We echo the calls of researchers and policymakers for urgent action to support paramedic mental health in Canada.

The design of multifunctional microcarriers has attracted significant attention because they combine various functions within a single system. In this study, we developed a set of multi-layered hydrogel microcarriers, which were first loaded with chemotherapeutic curcumin (CUR), then using the layer-by-layer (LbL) technique, coated through a polyelectrolyte shell consisting of chitosan (CHIT) or poly(allylamine hydrochloride) (PAH). As an outer layer with antimicrobial function, newly synthesised alkylene quaternary ammonium salt functionalised polyelectrolytes (A-QAS-PEs) were applied. For this purpose, poly(acrylic acid) (PAA) was decorated with dif-ferent hydrophobic side chains (n-hexane and n-dodecane side entities) and different degrees of substitution (m) of quaternary ammonium groups (abbreviated as PAA-C(O)O-(CH2)n-N+(CH3)3(m); n=6,12; m=8-14%). The grafting approach of PAA with the al-kylene quaternary ammonium salt moiety was performed under mild reaction conditions using Steglich esterification followed by quaternisation. The structure of antimicrobial decorated PAA was confirmed by 1H NMR and FTIR, and the mean diameter of all multifunctional microparticles was characterised by SEM. The viscoelastic properties of the functional layers were studied using QCM-D. The release of CUR from the microcarriers was described using a hybrid model, i.e., a combination of first-order kinetics and the Korsmeyer-Peppas model. The antimicrobial activity of functionalised PAA and multilayered CUR-loaded hydrogel microcarriers with quaternary am-monium function was assessed against Staphylococcus aureus and Serratia marcescens by the agar diffusion assay method. Only a limited inhibition zone of PAA was observed, but in the case of both antimicrobial decorated PAA and the corresponding multilayered nanocarriers, the inhibi-tory activity increase was achieved against both strains of bacteria.
Perspectives and Interpretations: Weighted Power Law Analyses of Three Short Works for Piano
Authors: Scott Douglas
Published: January 2022

Power law relationships, which describe scaling relationships of data, are powerful information theoretic descriptive tools in many empirical contexts, including that of music. Zipf’s law (pink noise) describes the optimum case of a power law relation where observations are exactly inversely proportional to their rank. Descriptions that approximate a pink noise signature can be said to maximize the amount of information in a signal, and is thus suggestive of a richness of an understanding. This information density of pink noise signatures is not, however, necessarily a desirable quality for explanations in general, which, by definition, “flattens out” some data while highlighting others, ideally those most relevant to an interpretation. The privileging of data most relevant to comprehension corresponds to a red noise relationship, as opposed to the pink noise of Zipf’s law or the white noise of a description that highlights nothing in particular. Here, I explore and evaluate this concept of red noise explanations in the form of analyses of three comparable short piano works: Robert Schumann’s “Von fremden Ländern und Menschen” (no.1 from Kinderszenen op. 15, 1838), Frédéric Chopin’s Prelude op. 28 no. 20 (1838-9), and Felix Mendelssohn’s “Venetianisches Gondellied” (no. 6 from Lieder ohne Worte op. 19b, 1829-30).
