The article discusses the application of the methodical apparatus of cluster analysis in order to rationalize and objectify the process of the complex physico-geographical regionalization. The results obtained by the qualitative data statistical proceedings concerning geology, land forms, insolation, moisture, soil and vegetation properties of the localities and represented by the elementary fields of the rectangular network on the maps of the studied area of the Dyje river basin, gave us a picture of the geoecological structure of the landscape in the model area. By combining the furthest neighbour method and simple matching coefficient we succeeded in setting up a hierarchical system of 12 types of geocomplexes, and a hierarchical system of the boundaries between them. The findings were shown on computer maps.
Subsidences Due to Underground Mining
Authors: Loyda Ludvík
Published: March 2022

The origin and evolution of sinkholes as well as of large subsidence depressions above underground excavations are explained by the changes in strain in rocks due to the mining activity. But on the periphery of the destructive ellipsoid the extension of rocks and the upheaval of the earth surface also take place, caused by the lowering of the strain. This phenomenon pertains not only to undermined areas but it also partakes in the upheaval of the borders of trogs and rifts, and all raised blocks of the earth's crust.

Published: March 2022

ABSTRACT

Tenebrio molitor is an insect larvae that has the potential as a protein source for poultry feed. However, no exploratory research has been found on the quality of poultry meat reared with feed containing these insect larvae. The purpose of this study was to evaluate the hedonic and hedonic quality characteristics of fresh and boiled chicken meat in terms of color, texture, aroma and taste of broiler chicken fed with Tenebrio molitor meal. This research method is experimental using a completely randomized design (CRD). As a treatment, there were two types of feed, namely feed containing 5% MBM as control (R0) and feed containing 5% Tenebrio molitor meal (R1). The treatment was repeated five times, ten chickens for each replication. The results of hedonic and hedonic quality observations were analyzed descriptively. Based on hedonic quality characteristics; the color of the raw meat is redder, the aroma is less fishy, and the taste of cooked meat is more savory. And, in hedonic; broiler chicken that is fed a feed containing Tenebrio molitor meal is preferred by the panelists. So it can be concluded that broiler chicken meat that is fed with Tenebrio molitor meal is better than chicken meat that consumes MBM.

How Can ‘Race’ Be Transcended in Cross Cultural Dialogues? Applying Critical Thinking to Show Human “Races” as Artificially Constructed
Authors: SOTELO Xiana
Published: March 2022

Abstract: In line with the cross ethnical alliances that the Eurasian community (from Asia) stands for, in this paper we interrogate the possibility of meaningful ways to transcend ‘race’ through the application of critical thinking skills. The methodology proposed
combines a brief historical summary of how race has been articulated in history and in science until the discovery of Human DNA with some references to the field of Race Studies. As a social value category, it will be demonstrated that ’race’ has no scientific evidence.In the
pursuit of objectively demonstrating that what unites us as humans is much more than what separates us, critical thinking can help us to go beyond nationality and transcend classifications. In doing so, a critical mindset will be underlined as a necessary requirement to increase the degree
of rigorous and truthful information generated from the sciences and humanities in the advancement of one human race within Eurasian community and beyond.
A Cultural Interpretation of the Holistic Success and Individual Obedience of China’s Fight against COVID-19 Crisis
Authors: WU Huiyong
Published: March 2022

Abstract: Possibly the main reason why China can completely control the COVID-19 pandemic is that it can use state power to implement holistic and systemic deployment, integrate all resources, and form an efficient and refined grassroots management system. The sense of responsibility
of the Chinese people has been a very important factor. The obedience of individuals in China does not come from the authority imposed by any external agent. It stems from its Confucian traditions and the positive pursuit of common ways of self-recognition and self-realization. These traditional
values are very different from the Western individualistic construction of modernity. China’s cultural orientation may not be replicated by other countries, but its way of shaping the people's sense of social responsibility and the holistic way of handling crises should be worthy of
study and reference.

Designing a Generalized PIO for Polytropic Discrete Time Systems
Authors: Rios-Bolivar Addison , Rivas Francklin
Published: March 2022

Considering the Linear Parameter Varying (LPV) systems of discrete time, in this paper an approach for the synthesis of robust Proporcional+Integral Observers (PIO) is presented. From LPV systems characterized with polytopical uncertainties, the method of design is based on considering a dynamics extended of the typical PIO, in order to transform the design of the matrices of the dynamics of the observer, as a design of the gain of Static Output Feedback (SOF) of a problem of robust control. Under these conditions and from the norms H2=H1 described as Linear Matrix Inequalities (LMI), the criteria to obtain the gain in the SOF problem are established; taking into account performance indices in H2 and H1, under the presence of uncertainties and disturbances.

Accuracy of mobile objects self-localization in radio frequency identification (RFID) tag networks depends on many environmental and design factors. This paper analyzes effect of such factors on estimates of the mobile object location. As an estimator, we use the extended finite impulse response (EFIR) filter. It is shown that accuracy of self-localization in the ultra high frequency (UHF) RFID tag networks can be increased by the factor of several times if to optimize design of the tag and network environment and obtain the optimal angle of arrival and viewing angle. Many other factors are also considered.
Towards Resilient Cyber-Physical eHealth Systems
Authors: Rajamäki Jyri
Published: March 2022

Current eHealth systems are cyber-physical systems (CPS) making safety-critical decisions based on information from other systems not known during development. To achieve the trust of users, measures of safety have to be taken into consideration in accordance with the ""privacy by design"" approach. This requires secure storage of information and guaranteeing safe exchange of data preventing unauthorized access, loss of data and cyber-attacks. From citizens’ point of view, eHealth is wholeness in which sectors of information security (availability/confidentiality/integrity) hold true. Present procedures emphasize confidentiality at the expense of integrity and availability, and regulations/instructions are used as an excuse not to change even vital information. The mental-picture of cyber security should turn from “threat, crime, attack” to “trust”. Creating confidence in safe digital future is truly needed in the integration of the digital and physical world’s leading to a new digital revolution. The precondition for the exchange of information “trust” must be systematically built at every CPS’ level (cyber, platform, and people).
An Algorithm with the Even-odd Splitting of the Wavelet Transform of Non-Hermitian Splines of the Seventh Degree, II
Authors: Shumilov Boris M.
Published: March 2022

In this study, the zeroing property of the first two moments is used to construct an algorithm for splitting spline wavelets of the seventh degree. The presentation is based on the system of basic spline wavelets of the seventh degree, constructed in the previous article, which implements the conditions of orthogonality to all polynomials of any degree. Then, using homogeneous Dirichlet boundary conditions, the system is adapted to orthogonality to all polynomials up to the first degree on a finite interval. Implicit finite relationships are obtained between the spline coefficients in the original scale, on the one hand, and the spline coefficients and wavelet coefficients in the nested scale, on the other hand. After eliminating the even rows of the system, the transformation matrix has seven diagonals instead of five, as in the previous case studied. The resulting system has been modified to ensure strict diagonal dominance and, hence, computational stability, in contrast to the fivediagonal case.
Parallel Execution on HeterogeneousMultiprocessors from Algorithm Models Based on Petri Nets
Authors: Wolfmann Gustavo
Published: March 2022

Current supercomputers are composed by nodes containing a combination of general purpose computing units (CPUs) and specific mathematical coprocessors. In this way, GPGPUs or Xeon Phi cards are attached to the nodes to improve its performance. Both types of processors, CPUs and coprocessors, have many differences, like their architecture, the clock rate of the processors and the operation of the related memory. These are the main factors that conform an heterogeneous multiprocessor. A parallel program that wants to achieve the sum of the performance of both types of processors, must consider not only the complexity of the parallel algorithm, but also the differences in the architecture of processors, increasing its complexity. As a contribution on this problem, this paper presents a model of parallel execution based on Petri Nets, called PN-PEM, that is used not only to model a parallel algorithm, but also to execute it directly on a computer with heterogeneous multiprocessors. An asynchronous execution of tasks and a dynamic scheduler are the main characteristics that allow execute a parallel program on this type of parallel computer. Tests done on a multicore computer with two Xeon Phi cards reach the aggregate performance of both type of processors, confirming the quality of the model used.

Published: March 2022

Recycling of aggregates separated from industrial wastes becomes more important than ever because of increasing demand of urban redevelopment. The purpose of this study is to investigate the operating principle of a newly developed paste separator equipped with a rotor. We constructed one-dimensional model for the air flow and the particle motion is assumed to be governed by the air drag, centrifugal and gravitational forces. We demonstrate that there are several sections on the air flow route, where particle motions are stationary along the stream-wise direction while rotating in the azimuthal direction, called quasi-stagnant state. It was shown that it plays a key role in separation of particles. We report the critical curve in the parametric space where we can predict separation or non-separation of a given particle size, flow rate and rotor speed.

Published: March 2022

Review question / Objective: The purpose of this study is to summarize the characteristics of RCT in the treatment of obesity by acupuncture and other related intervention measures, so as to enhance evidence-based clinical practice about acupuncture for obesity. Condition being studied: Obesity is a chronic metabolic disease that is defined as a body's excessive accumulation or abnormal distribution of total or local fat content. Their complications such as Type II diabetes mellitus, hyperlipidemia, and cardiovascular diseases are strongly related to higher risks of mortality. In recent years, with the changes in diet structure and living habits, 1.9 billion adults were overweight and over 650 million were obese according to the report by the WHO in 2016. Acupuncture is a characteristic therapy of traditional Chinese medicine, which is effective and safe for the treatment of simple obesity. In recent years, many RCTs using acupuncture in simple obesity were carried out within and outside of China. But currently, acupuncture treatment has no uniform standard, and there are a number of problems with this current clinical application of modern Chinese Medicine. Unfortunately, there is an absence of high-quality data supporting their use. This scoping review aims to summarize the characteristics of RCT in the treatment of obesity by acupuncture and other related intervention measures, so as to enhance evidence-based clinical practice about acupuncture and moxibustion for obesity.

Authors: ALTIN Duygu , KESKİN Deha Denizhan
Published: March 2022

Aim: Cervical cancer screening guidelines gradually recommend human papillomavirus (HPV) DNA testing since sensitivity of cytology is relatively low. This study aimed to evaluate correlation between HPV, cervical smear cytology and colposcopy directed biopsy results.

Material and Methods: Patients who underwent colposcopy directed biopsy in Ordu University Training and Teaching Hospital between January 2018 and December 2021 were retrospectively reviewed. Patients with any high-risk HPV positivity who had cervical smear cytology and colposcopy directed biopsy results were included to this study. Results of HPV subtypes, cervical smear and histologic biopsy were recorded.

Results: A total of 734 patients were included to this study. The mean age of the patients was 41.9 ± 7.36 years. Hundred and sixty-five (22.5%) patients had HPV 16 alone, 35 (4.8%) had HPV 18 alone, 354 (48.2%) had other high-risk HPV subtypes alone and 180 (24.5%) had more than one high-risk HPV subtypes. Two hundred and ninety-eight (40.6%) had HPV 16 or HPV 18 either alone or in combination with other subtypes. Majority of the patients (55.3%) had normal cervical smear results followed by ASC-US (27%). Colposcopy directed biopsy results were as follows: 452 (61.6%) normal, 199 (27.1%) CIN 1, 36 (4.9%) CIN 2, 42 (5.7%) CIN 3 and 5 (0.7%) squamous cell cancer. 66.1% of the patients with HPV 16 and/or HPV 18 had normal cervical cytology results, but they had significantly more ≥CIN 2 lesions compared to other high-risk HPV subtypes (19.8% vs 5.5%, p

Published: March 2022

INTRODUCTION:

While endovascular coiling has been shown to be a safe treatment option for intracranial aneurysms, there remains concern regarding increased recurrence and retreatment rates. Preliminary studies evaluating hydrogel coated coils have demonstrated decreased recurrence rates compared to bare metal coils.

METHODS:

A retrospective chart review was done on all patients with anterior communicating artery aneurysms (ACoAAs) treated with endovascular coiling between 2014 and 2018. Treatment groups were divided into hydrogel coated coils or bare metal coils. Patients were categorized into the hydrogel group when ≥ 70% of the coil length was hydrogel coated.

RESULTS:

Eighty-four ACoAAs were treated with coil embolization between 2014 and 2018. Postoperative imaging was available for 68 patients. Twenty-six patients were categorized into the hydrogel treatment group. Aneurysm recurrence was seen in 7.7% (2/26) of patients treated with hydrogel coated coils compared to 33.3% (14/42) of those treated with bare metal coils (P = 0.03). Subanalysis of patients with ruptured aneurysms revealed decreased recurrence rates in patients treated with hydrogel coated coils at 5.9% (1/17) compared to patients treated with bare metal coils at 39.4% (13/33) (P = 0.01).

CONCLUSIONS:

Hydrogel-coated coils may reduce recurrence rates in the treatment of both ruptured and unruptured ACoAAs.

Dilemmas in managing coexisting arteriovenous and cavernous malformations
Authors: Fotakopoulos George , Brotis Alexandros G. , Fountas Kostas N.
Published: March 2022

Coexisting arteriovenous malformations (AVMs) and cavernous malformations (CMs) are rare. Here, we present our dilemmas in managing a patient with a cerebral AVM and a pontine CM. A 47-year-old patient suffered from headaches, vomiting, and transient swallowing difficulties. The cerebral computed tomography showed a pontine hyperintense lesion, while the axial magnetic resonance imaging of the head disclosed a frontal interhemispheric AVM and a CM located in the rostral and ventral aspect of the pons. Despite a pontine hemorrhage, the patient underwent microsurgical excision of the frontal lesion in the first place, due to the increased bleeding risk, followed by stereotactic radiosurgery of the pontine CM. On the 6 months follow-up, the patient's clinical status was stable. A reasonable treatment strategy based on risk stratification is paramount in managing patients with coexisting AVMs and CMs. The optimal outcome frequently requires a staged multidisciplinary approach.

Published: March 2022

Current guidelines do not include radiologic assessment of the carotid arteries before catheter ablation procedures. There are multiple studies describing the risks of periprocedural cardioembolic strokes during cardiac ablation procedure but none describing the risks of periprocedural watershed strokes due to hypoperfusion during cardiac ablation. It is critically important for neurologists, cardiologists, and all other associated health-care workers to recognize the risks of neurologic complications, such as watershed strokes, before cardiac procedures are performed. We are presenting an 84-year-old male who presented to the emergency room with complaints of vision changes after a cardiac ablation procedure for atrial fibrillation. He described spotty vision with decreased visual acuity in both eyes. Magnetic resonance imaging of the brain showed multiple strokes bilaterally. Based on the radiologic features, all the strokes happened at approximately the same time. Of note, subsequent computed tomography angiography of the head and neck showed 65%–70% bilateral stenosis of the internal carotid arteries.

Published: March 2022

BACKGROUND:

Recurrent strokes cause greater complications and worse outcomes by adding to the existing neurological deficit. There is the paucity of data on serum markers of inflammation as predictors of recurrent stroke. This study was planned to analyze the clinico-etiological profile of recurrent noncardioembolic ischemic stroke, estimate aspirin resistance among regular aspirin users and evaluate blood biomarkers high-sensitivity C-reactive protein (hsCRP), Tumor necrosis factor-alpha (TNF-α), Lipoprotein-associated phospholipase A2 (Lp-PLA2) as probable predictors of stroke recurrence.

METHODS:

Patients of recurrent noncardioembolic ischemic stroke fulfilling the inclusion criteria were enrolled. Detailed history, clinical examination, and investigations were obtained as per protocol. Aspirin resistance was determined by light transmission aggregometry. Serum hsCRP, TNF-α, and Lp-PLA2 levels were estimated.

RESULTS:

This study included 34 males and 16 females. Majority of the patients were > 60 years (n = 30, 60%). Thirty (60%) cases had a repeat stroke after 1 year of primary event. Thirty-nine (78%) study participants had hypertension, while 15 (30%) had diabetes. Middle cerebral artery (n = 40, 80%) was the most common vascular territory. Thirty-one (62%) cases belonged to TOAST subtype 1 (large artery atherosclerosis). Seventy two percent cases were prescribed aspirin after index stroke, but only 36% were compliant. Median (range) hsCRP level was 7.5 (0.3–155) mg/L with 72% of patients having high hsCRP level (>3 mg/L). Median (range) serum PLA2 level was 11.98 (3.31–87.24) ng/ml in patients and 6.96 (0.15–61.42) ng/ml in controls (P = 0.029). Median (range) serum TNF-α level in patients was significantly higher than controls (68.22 [1.3–287] pg/ml versus 0.098 [0.002–36.31] pg/ml, P < 0.001). Aspirin resistance was found in 41.7% patients while 16.7% were semi-resistant. Mean % platelet aggregation was 34.75 ± 21.58 in patients and 64.75 ± 16.98 for controls (P < 0.001).

CONCLUSIONS:

Majority of patients with recurrent stroke were elderly (>60 years), hypertensive, and non-compliant with aspirin. Aspirin resistance was an important factor in patients with antiplatelet compliance. Inflammatory biomarkers hsCRP, PLA2, and TNF-α were found to be significantly elevated in patients compared to controls.

Published: March 2022

OBJECTIVE:

Proper blood flow is essential for the maintenance of homeostasis for the human cerebrum. The dural venous sinuses comprise the dominant cerebral venous outflow path. Understanding the spatial configuration of the dural venous sinuses can provide valuable insight into several pathological conditions. Previously, only two-dimensional or cadaveric data have been used to understand cerebral outflow. For the first time, we applied three-dimensional rotational venography (3D-RV) to study and provide detailed quantitative morphological measurements of the terminal cerebral venous sinus system in several pathological states.

SUBJECTS AND METHODS:

Patients who underwent a 3D-RV procedure were identified by reviewing our local institution's endovascular database. Patients with high-quality angiographic images were selected. Eighteen patients were included (37.1 ± 3.8 years). Sinuses were divided into four segments, starting at the torcula and ending at the internal jugular vein. Segment length, 3D displacement, and cross-sectional area were measured.

RESULTS:

The transverse sinus (60.2 mm) was the longest segment, followed by the sigmoid sinus (55.1 mm). Cross-sectional areas were smallest at the middle of the transverse sinus (21.3 mm2) but increased at the sigmoid sinus (33.5 mm2) and at the jugular bulb (49.7 mm2). The only variation in displacements of venous flow was at the sigmoid-jugular junction, where 55% of cases had lateral displacements versus 45% medial, and 78% superior versus 22% inferior.

CONCLUSIONS:

We describe the terminal venous sinus system of patients with a variety of diagnoses, detailing segment length, cross-sectional area, and 3D path.

Children who often receive and get disapproval, fear, and feel disappointment will cause children to lose their confidence. This will continually occur until they grow up if it consents. This will greatly interfere the children's development in many ways. What parents can do in developing children's self-confidence are that they should 1) appreciate whatever the children got, 2) wisely praise in order not to be arrogance, 3 wisely criticize without blaming, 4) support their abilities; never compare them with other children, 5) establish a harmonious relationship. Institutions for early childhood can optimize the development of students’ self-confidence by 1) Familiarizing self-confidence through independent aspects, 2) Familiarizing self-confidence through expressing ideas, and 3) implementing learning methods that aim to increase student's self-confidence.
