Authors: A. Al-Rikaby Maitham , J. Al â€“ Shamma Kasim , A. Majeed Ibrahim , SH.Hamondi Saad
Published: March 2022

Hypertension is identified as one of the most significant risk factors for cardiovascular diseases (CVDs). There is growing evidence showing that oxidative stress plays a major role in hypertension. Increased production of reactive oxygen species and decrease bioavailability of antioxidant have been demonstrated in experimental and human hypertension. The present study was directed to determine the beneficial effect of the antioxidant vitamin C in patients with essential hypertension treated with the calcium channel blocker (amlodipine) or with the angiotensin converting enzyme inhibitor (enalapril). Ninety six patients (50 females and 46 males) with essential hypertension and treated with amlodipine or enalapril, age (50.43 Â± 0.55 year) were participated in this study and divided in to: Twenty five patients received amlodipine 5mg tablet once daily (group 1), twenty five patients received the same dose of amlodipine plus 500mg of vitamin C tablet twice daily (group 2), twenty three patients received enalapril 5 mg tablet once daily (group 3), and twenty three patients received the same dose of enalapril plus 500mg of vitamin C tablet twice daily (group 4). Twenty apparently healthy subjects (11 females and 9 males) also participated in this study as control group (group 5). All patients were treated and followed up for one month. The mean blood pressures were measured for each patient before treatment and one, two, three and four weeks after treatment. Serum malondialdehyde (MDA), lipid profile, electrocardiogram (ECG) parameters and heart rate were measured for each patient before treatment and two and four weeks after treatment. The addition of vitamin C to amlodipine or enalapril treated patients had resulted in a significant (p<0.05) lowering effect on mean blood pressure after two, three and four weeks. On the other hand, the addition of vitamin C to amlodipine or enalapril treated patients had resulted in a significant lowering of serum MDA after two and four weeks of treatment. While there was no significant change in lipid profile or ECG parameters and heart rate of patients in group two and four after two and four weeks of vitamin C treatment as compared to their values at zero time and to patients in group one and three respectively. The study indicates that oxidative stress may have a significant role in essential hypertension, and addition of the antioxidant vitamin C to antihypertensive drugs used in this study can give a good blood pressure lowering effect and good protection against lipid peroxidation.

PREPARAÇÃO DE AULAS REMOTAS MEDIADAS POR TDIC
Authors: Ayres de Oliveira Neto Frederico
Published: March 2022

A evolução tecnológica dos últimos quarenta anos provocou diferenças perceptíveis entre as gerações, impactando na comunicação em ambientes pedagógicos, intensificada com a pandemia pela COVID-19. As TDIC (Tecnologias Digitais da Informação e Comunicação) foram adotadas em um regime de urgência sem o devido planejamento, resultando em transferência inadequada de procedimentos didático-pedagógicos do ensino presencial para o remoto. Professores sem o devido letramento digital foram constrangidos a utilizar ferramentas digitais nas aulas, refletindo na valorização exacerbada dos recursos digitais em detrimento dos conceitos nas áreas específicas. Embora sejam inevitáveis os afastamentos pedagógico e psicológico, é possível minimizá-los com a integração de professores, seja pela interdisciplinaridade, seja por planejamentos em conjunto, superando a inadequada capacitação tecnológica. Esse trabalho apresenta uma sequência de encontros com o objetivo de planejar aulas durante um curso de uso de ferramentas digitais para o ensino de ciências naturais, visando aplicar os recursos para o desenvolvimento dos conceitos em química, biologia e física. Os participantes do curso se agruparam espontaneamente em suas áreas e propuseram aulas com o uso de TDIC. Com as atividades em grupos, o planejamento das aulas foi favorecido, uma vez que cada participante contribuiu com sua perspectiva e com sua experiência.

OBJECTIVE

Sports injuries are known to present a high risk of spinal trauma. The authors hypothesized that different sports predispose participants to different injuries and injury severities.

METHODS

The authors conducted a retrospective cohort analysis of adult patients who experienced a sports-related traumatic spinal injury (TSI), including spinal fractures and spinal cord injuries (SCIs), encoded within the National Trauma Data Bank from 2011 through 2014. Multiple imputation was used for missing data, and multivariable linear and logistic regression models were estimated.

RESULTS

The authors included 12,031 cases of TSI, which represented 15% of all sports-related trauma. The majority of patients with TSI were male (82%), and the median age was 48 years (interquartile range 32–57 years). The most frequent mechanisms of injury in this database were cycling injuries (81%), skiing and snowboarding accidents (12%), aquatic sports injuries (3%), and contact sports (3%). Spinal surgery was required during initial hospitalization for 9.1% of patients with TSI.

Compared to non-TSI sports-related trauma, TSIs were associated with an average 2.3-day increase in length of stay (95% CI 2.1–2.4; p < 0.001) and discharge to or with rehabilitative services (adjusted OR 2.6, 95% CI 2.4–2.7; p < 0.001). Among sports injuries, TSIs were the cause of discharge to or with rehabilitative services in 32% of cases. SCI was present in 15% of cases with TSI. Within sports-related TSIs, the rate of SCI was 13% for cycling injuries compared to 41% and 49% for contact sports and aquatic sports injuries, respectively. Patients experiencing SCI had a longer length of stay (7.0 days longer; 95% CI 6.7–7.3) and a higher likelihood of adverse discharge disposition (adjusted OR 9.69, 95% CI 8.72–10.77) compared to patients with TSI but without SCI.

CONCLUSIONS

Of patients with sports-related trauma discharged to rehabilitation, one-third had TSIs. Cycling injuries were the most common cause, suggesting that policies to make cycling safer may reduce TSI.

OBJECTIVE

Adult spinal deformity is a complex pathology that benefits greatly from surgical treatment. Despite continuous innovation, little is known regarding continuous changes in surgical techniques and the complications rate. The objective of the current study was to investigate the evolution of the patient profiles and surgical complications across a single prospective multicenter database.

METHODS

This study is a retrospective review of a prospective, multicenter database of surgically treated patients with adult spinal deformity (thoracic kyphosis > 60°, sagittal vertical axis > 5 cm, pelvic tilt > 25°, or Cobb angle > 20°) with a minimum 2-year follow-up. Patients were stratified into 3 equal groups by date of surgery. The three groups’ demographic data, preoperative data, surgical information, and complications were then compared. A moving average of 320 patients was used to visualize and investigate the evolution of the complication across the enrollment period.

RESULTS

A total of 928/1260 (73.7%) patients completed their 2-year follow-up, with an enrollment rate of 7.7 ± 4.1 patients per month. Across the enrollment period (2008–2018) patients became older (mean age increased from 56.7 to 64.3 years) and sicker (median Charlson Comorbidity Index rose from 1.46 to 2.08), with more pure sagittal deformity (type N). Changes in surgical treatment included an increased use of interbody fusion, more anterior column release, and a decrease in the 3-column osteotomy rate, shorter fusion, and more supplemental rods and bone morphogenetic protein use. There was a significant decrease in major complications associated with a reoperation (from 27.4% to 17.1%) driven by a decrease in radiographic failures (from 12.3% to 5.2%), despite a small increase in neurological complications.

The overall complication rate has decreased over time, with the lowest rate of any complication (51.8%) during the period from August 2014 to March 2017. Major complications associated with reoperation decreased rapidly in the 2014–2015. Major complications not associated with reoperation had the lowest level (21.0%) between February 2014 and October 2016.

CONCLUSIONS

Despite an increase in complexity of cases, complication rates did not increase and the rate of complications leading to reoperation decreased. These improvements reflect the changes in practice (supplemental rod, proximal junctional kyphosis prophylaxis, bone morphogenetic protein use, anterior correction) to ensure maintenance of status or improved outcomes.
Unconstitutionality of the 2021 Military Coup in Myanmar
Authors: Noel Thibaut
Published: March 2022

Since the coup conducted by the Myanmar military on 1 February 2021, the military regime has attempted to portray itself as the country’s legitimate government by arguing that it is adhering to the 2008 Constitution. Although constitutional authority is only one dimension of the current struggle to restore democratic governance in Myanmar, it is important to demonstrate why the military’s seizure of power was unconstitutional, and therefore why the military regime and its actions and decisions have no constitutional authority. This Brief was developed to enable a better understanding of the unconstitutionality of the military coup in Myanmar. It helps deconstruct the military regime’s claim that it is adhering to the 2008 Constitution.

On the inevitability of the development and adoption of a new Constitution of the Russian Federation and what should be in her (The end)
Authors: Kleandrov Mikhail I.
Published: March 2022

Based on a scrupulous analysis of the chronology and essential characteristics of the amendments to the Constitution of the Russian Federation in 1993, the author came to the conclusion about a clear periodization of these changes (2008 - 2014 - 2020), and after six years, a pattern of projecting the inevitability of the adoption of a new Constitution of the Russian Federation is seen - approximately in 2026. Confirmation of the objective need for a new Constitution are also: the initial defect of a number of constitutional provisions contained in chapters 1 and 2 of the Constitution of the Russian Federation in 1993, which cannot be changed without the adoption of a new Constitution of the Russian Federation; the resulting contradictions (explicit and implicit) between the constitutional provisions contained in сhapters 1 and 2 of the Constitution of the Russian Federation, on the one hand, and chapters 3 - 8, on the other hand; the defectiveness of a number of innovations to the Constitution of the Russian Federation made in 2020 (primarily related to the constitutional foundations of the justice mechanism); and most importantly, it is possible to construct the new Constitution of the Russian Federation in 2026 on a qualitatively different basis with a focus on the future, with a happy society, a highly efficient state structure, a strong economy, etc., which should be based on a national idea, the core of which will be justice sacred to our society. Specific proposals are being made, including what the new Constitution of the Russian Federation should contain.
On the rotation of persons holding the presidency: experience in scientific comprehension
Authors: Cherepanov Victor A.
Published: March 2022

On the basis of a comparative analysis of the constitutional models of different countries the approach, that considers the rotation of power not as a goal in itself, but as a means of avoiding the alienation of power from the people, has been proposed. Taking into account this analysis, the pattern of the presidential power, consisting of two interrelated parts, has been justified. Firstly, based on a critical rethinking of the optimality of two-term model of the rotation of the presidential power for all countries the author has formulated the provision that depending on the balance of political forces, historical experience, social traditions and values, different countries establish their own model which considered acceptable in a particular country on the condition of its legal legitimization. Secondly, the provision on the need to establish in Russian legislation the institution of recall of the President of the Russian Federation, who has not lived up to public expectations, by the will of the people, expressed in a national referendum, has been justified.

Authors: Liu Gaochuan , Shan Weifeng , Chen Jun , Che Mengqi , Teng Yuntian , Huang Yongming
Published: March 2022

Geomagnetic interference events seriously affect normal analysis of geomagnetic observation data, and the existing manual identification methods are inefficient. Based on the data of China Geomagnetic Observation Network from 2010 to 2020, a sample data set including high voltage direct current transmission (HVDC) interference events, other interference events and normal events is constructed. By introducing machine learning algorithms, three geomagnetic interference event recognition models GIEC-SVM, GIEC-MLP, GIEC-CNN are designed based on support vector machines (SVM), multi-layer perceptron (MLP) and convolutional neural networks (CNN) respectively. The classification accuracy for each model on the test set reached 76.77%, 84.96% and 94.00%. Two optimal GIEC-MLP and GIEC-CNN are selected and applied to the identification of geomagnetic interference events at stations not participated in training and testing from January, 2019 to June, 2021. The accuracy are 72.11% and 78.24% respectively, while the efficiency is 150 times that of manual identification. It shows that the geomagnetic interference event recognition algorithm based on machine learning algorithm has high recognition accuracy and strong generalization ability, especially the CNN algorithm.
A rapid prediction algorithm suitable to portable device for animal body-temperature measurement
Authors: Zhu Qi-Wen , Gu Bin , Ji Liang , Sun Dong , Liu Yu-Dong , Yu Bao-Ming
Published: March 2022

The body-temperature is the most significant vital signs of human and animals. It is easily imaginable that measurement of body-temperature of animals will be much more difficult than that of human being due to lack of endurance or fear of measuring instrument. Infrared temperature measurement device may be a solution, however coverage of hair and fur may incur a large error. To address this issue, a rapidly executed algorithm is developed for prediction of steady state body temperature, which needs only a few one-tenth of measurement duration that the currently popular machine learning-based approach usually requires. Let a cubic function c⁢(t) fit the sampled temperature data which are generated by the measurement within a significantly short duration from tn-k to tn,k>0. Then let a quadratic function f⁢(t)=a2⁢t2+a2⁢t+a as a prediction function go through the point (tn,c⁢(tn)) and share the same slope of sn thereat. Finally try to find a next point (tn+m,f⁢(tn+m)), m>0, where the slope satisfies sn+m=sn/2 and m depends strongly on sn through an empirical formula. Accordingly, f⁢(t) can be determined by (tn,c⁢(tn)), sn and sn+m. Experiments indicate that the maximum of f⁢(t) approaches well the steady state temperature of the measured subject with a quite small error.

Authors: Wang Shuang , Liu Tingting , Ding Lei
Published: March 2022

Different feature extraction techniques are used to build AirFare-FS model, which is an integrated ticket price-prediction model, to solve the nonlinear regression problem of ticket price-prediction. Using three public air ticket datasets as an example, the AirFare-FS model identify main features affecting the air ticket price in each dataset and constructs a feature subset of each dataset using eleven feature extraction methods. Then, the AirFare-FS model selects the best feature subset of each dataset using a multi-objective optimization method. Finally, the optimal subset is used to find the best prediction method with the highest matching degree, and the dynamic adaptive model is constructed. The results show that the best feature subset of SixAirlines and EaseMyTrip datasets is subset 4 and the best matching prediction model is gradient descent, while the best subset of flight prices is subset 3 and the best matching prediction model is random forest. The visualization technology is used to show the effect of the characteristics of each optimal feature subset on the ticket price. The results indicate that the flight time dominantly affects the ticket price.

Published: March 2022

Reasonably allocating the micro factor investment in the industry and trying to improve the energy efficiency are very important for the green development of industrial economy in Hebei Province, so as to the achievement of its double carbon target. This paper takes industrial energy consumption, assets and labor in Hebei Province as micro-input elements. Based on the panel data of 34 industrial industries in Hebei Province from 2005 to 2016, we identify the correlation of micro-input factors in different industries and conduct Granger causality test. The study shows that: (1) About half of the industry’s combined energy consumption is correlated with the number of employees and assets; About two-thirds of the industry’s asset workers are relevant; (2) There is a two-way causal relationship between the total energy consumption and assets of most industries and the annual average number of employees. (3) The rational allocation of capital, labor and energy consumption depends on the deepening reform of the factor market. The high energy consumption industry should actively improve and innovate the energy technology in this process to realize the coordinated promotion of energy saving and carbon reduction, and thus to promote the healthy and sustainable development of the industry steadily.

Study with descriptive design, which included 967 patients with pneumonia hospitalized between 2016 and 2019, and whose information was obtained from clinical records. Statistical treatment included bivariate and multivariate analysis (logistic regression); it was used the ratio of crossed products (odds ratio) and its 95% confidence interval. Several manifestations were significantly more frequent in older adults: dyspnea (OR 1.5[1.07,2.1]), absence of productive cough (OR 1.7 [1.3, 2.4]), neuropsychological manifestations (OR 2 [1.4,2.8]), tachypnea (OR 1.5 [1.1,2.1]), arterial hypotension (OR 2.1 [1.2,3.6]) , anemia (OR 1.6[1.2,2.2]), elevated creatinine (OR 1.6[1.2,2.3]) and hypoproteinemia (OR 3.3[1.9,5.7]); showed a significant association with death: absence of productive cough, neuropsychological manifestations, temperature below 36 degrees Celsius, blood pressure below 110/70 mmHg, respiratory rate above 20 per minute, hemoglobin below 100 g/L, erythrosedimentation greater than 20 mm/L, leukopenia less than 5 x 109/L and serum creatinine above 130 micromol/L. As conclusions certain clinical and laboratory conditions present in the patient at the time of hospital admission, of routine exploration in the comprehensive assessment of the patient, were predictors of death. Additionally, the existence of evident differences in the number of conditions with a predictive nature of death between the population with pneumonia under 60 years of age and the elderly, as well as in the frequency of these conditions in both subgroups, is verified.

Study to Find Out the Efficacy of 6 Minute Walk Test in Assessing Response to Medical Intervention in Chronic Obstructive Pulmonary Disease Patients
Authors: Sharma Brij Lal
Published: March 2022

Background: The aim was to find out the correlation of 6 minute walk test (6MWT) with spirometry values, in patients who are on treatment for chronic obstructive pulmonary disease, also to study the efficacy of the 6 MWT in assessing response to medical intervention in patients suffering from COPD. This was undertaken with an objective to study whether 6 MWT can be recommended for a primary care setting in resource-constrained countries in effective management of COPD

Methods: We included 50 patients with stable COPD attending the outpatient department in the stipulated study period and diagnosis of COPD was established by clinical symptoms and spirometric data of ratio of FEV 1 and forced vital capacity (FVC) ? 0.7. 

Results: The 6 minute walk distance (6MWD) of the patients was assessed once the health status of the patients has been stabilized. This was done under strict monitoring, just before discharge of the patient from the hospital. Participants aged less than 60 years had a 6MWD of 342.13±19.36 m while those aged above 60 years clocked 286.36±20.13 m.

Conclusions: 6MWT can be a useful replacement of spirometry in assessment of severity of COPD.

I diritti umani nella Guerra Fredda. Nuove proposte e nodi interpretativi
Authors: Tulli Umberto
Published: March 2022

Negli ultimi anni, gli storici hanno scoperto i diritti umani e avanzato una nuova interpretazione della loro storia negli anni della Guerra Fredda. Lungi dal proporre una storia lineare e trionfalista, gli studiosi si stanno concentrando sulle contraddizioni ed ambiguità dei diritti umani. Questa rassegna storiografica sottolinea alcuni tratti comuni alla nuova storiografia sui diritti umani: primo, sembra abbandonare la storia del diritto per dialogare con la storia politica, la storia delle relazioni internazionali e la storia transnazionale. Secondo, contribuisce a ridefinire e complicare la storia della Guerra Fredda, mostrando punti di contatto e di intersezione tra due storie che hanno difficilmente dialogato tra loro. Vi sono però dei limiti che sembrano poter fare emergere un nuovo approccio trionfalistico alla storia dei diritti umani.
Спільне використання мобільної радіологічної лабораторії та системи підтримки прийняття рішень як ефективний підхід до аварійного моніторингу
Authors: Balashevska Yu. , Demchenko M. , Kyrylenko Yu. , Kotsuba O. , Pecherytsa O. , Shevchenko I.
Published: March 2022

Проведення радіаційного обстеження та оперативний аналіз розповсюдження забруднення на прилеглих до АЕС територіях під час важкої аварії забезпечують надійне підґрунтя для прийняття рішень щодо вжиття дій та невідкладних контрзаходів для захисту персоналу і населення. Проте на практиці вибір просторово-часових параметрів вимірювань та пробовідбору часто ускладнений, зокрема несприятливою радіаційною обстановкою або обмеженістю в часі для збору даних тощо.

Якщо на ранніх етапах реагування для прийняття рішень щодо впровадження захисних заходів може бути достатньо попередніх результатів моделювання атмосферної дисперсії радіоактивних речовин та оцінки доз опромінення для постульованого сценарію розвитку подій, то з надходженням перших результатів моніторингу, задля уточнення моделі та забезпечення підстав для інтерпретації її результатів, виникає потреба у підсиленні інструментів прогнозування радіаційних наслідків використанням їх сумісно із засобами мобільного моніторингу.

Наявні методики та рекомендації МАГАТЕ щодо аварійного моніторингу залишають простір для впровадження можливостей сучасних інструментів моделювання. Ця стаття містить перші напрацювання для розробки методології спільного використання системи підтримки прийняття рішень та мобільної лабораторії з метою успішного проведення аварійного моніторингу навколишнього середовища у реальному часі. Наведені у ній результати дослідження, виконаного в межах координованого дослідження МАГАТЕ CRP J15002, стосуються сумісного використання мобільної радіологічної лабораторії RanidSONNI та європейської системи підтримки прийняття рішень JRODOS.

Застосовані підходи ґрунтуються на нинішньому досвіді Державного підприємства «Державний науково-технічний центр з ядерної та радіаційної безпеки» у підтвердженні результатів моделювання реальними даними вимірювань параметрів радіаційної обстановки, наданими мобільною лабораторією під час реагування на лісові пожежі в зоні відчуження і зоні безумовного (обов'язкового) відселення протягом останніх років.

Risk-informed decision-making approaches in the field of regulatory inspections performed at the NPPs aim at supporting the regulatory body in better organization of inspections. The paper describes the Armenian national experience of inspection activities by focusing on the process of significance assessment of inspection findings and demonstrates its applicability on practical examples. To demonstrate the applicability of the proposed process, various hypothetic inspection findings are defined for further assessment. Approaches are proposed for the significance determination of single and multiple findings. Several cases of single hypothetic findings and their combinations are considered. The paper summarizes the results for the considered cases, which reveal the applicability of the process by demonstrating the significance of hypothetic findings and the cumulative effects of multiple simultaneous hypothetic findings on plant safety.
Аналіз питань нормативного забезпечення діяльності з підготовки до зняття АЕС з експлуатації
Authors: Pysmennyy Y. , Filatov V. , Boyko N.
Published: March 2022

Нині на АЕС України знаходяться в експлуатації 15 енергоблоків. Враховуючи проєктний строк експлуатації та його продовження, зняття з експлуатації 12 з них очікується починаючи з 2030 року. Законодавча та нормативна база, що містить вимоги до зняття АЕС з експлуатації, особливо вимоги до підготовчої та початкової діяльності набула чинності більше 10 років тому. На початку 2021 року набув чинності нормативний документ, що значною мірою змінив вимоги до забезпечення безпеки та змісту діяльності під час зняття з експлуатації ядерних установок. У цій статті проведено аналіз положень нового нормативного документа «НП 306.2.230-2020. Загальні положення безпеки зняття з експлуатації ядерних установок» стосовно саме АЕС та їх енергоблоків, а також виконано аналіз відповідності проведеної діяльності з підготовки до зняття з експлуатації діючих АЕС та їх енергоблоків вимогам нового нормативного документа. З огляду на наведену в новому нормативі структуру документів, які регламентують зміст діяльності зі зняття з експлуатації та послідовності дій з їх розробки та супроводу, запропоновано загальний підхід до розробки стратегії зняття з експлуатації АЕС і надано пропозиції щодо коригування чинних концепцій зняття діючих АЕС з експлуатації. Надано пропозиції щодо внесення змін у чинні нормативні та технічні документи, що регламентують такі напрями підготовчої діяльності та очікуваного початку процесів зняття з експлуатації енергоблоків АЕС України, як проведення комплексного інженерного та радіаційного обстеження, розробка проєкту зняття з експлуатації, функціонування системи інформаційного забезпечення зняття з експлуатації.
