‘Cut and push’ as an alternative to endoscopic retrieval of PEG type gastrostomy tubes
Authors: Claxton Harry , Dick Karen , Taylor Rhoda , Allam Maddie , Stedman Francesca , Keys Charlie , Hall Nigel J
Published: December 2022

Purpose:

Percutaneous Endoscopically placed Gastrostomy (PEG) tubes are frequently used in children. The traditional endoscopic method to remove/change the PEG device requires general anaesthesia in children. A minimally invasive alternative is the ‘Cut and Push’ method (C&P): avoiding the risks/wait times of general anaesthesia and reducing resource burden. Data regarding safety/effectiveness of C&P in children are lacking with concerns raised about the possibility of gastrointestinal obstruction.

Methods:

We retrospectively reviewed all cases of PEG removal / change to button in children (<18yrs) between December 2020 and January 2022. Cases were identified from a prospectively maintained database and all cases of C&P included. Parents/carers were asked if the child had suffered any complications following C&P and if flange was visualised in stools.

Results:

During the time period, 27 PEGs were either removed or changed to button via C&P. The average waiting time for C&P was 14.29 days, significantly shorter than the minimum 6 month waiting time for elective endoscopy. Our evaluation revealed no complications of C&P at median 70 days (range 25-301). In three cases the flange was visualised in the stool, at 2 days, 3 days and 5 weeksfollowing C&P respectively.

Discussion:

These data support the available literature suggesting C&P is an effective means to facilitate minimally invasive and prompt PEG removal / change to button in children. We recommend minimum weight and age parameters for this procedure and further evaluation of the safety and resource implications of this technique.
EstuarIndex: an eco-geomorphological index to assess the conservation state of estuaries
Authors: Aranda M. , Gracia F. J. , Peralta G.
Published: December 2022

The main objective of this work is to present a novel methodology to assess the vulnerability of mid-latitude estuaries by means of an index-based method, EstuarIndex. The EstuarIndexis an integration of four sub-indexes, assessing the status of the main subsystems present on estuaries: sandy environments, dunes, tidal flats, and the drainage network. Each sub-index includes variables combining three types of factors: morphosedimentary and oceanographic factors, ecological factors and management and protection factors. The environmental status is finally evaluated in five possible classes: (1) Very low, (2) Low, (3) Medium, (4) High and (5) Very High, according to EU requirements for classifying the conservation status of habitats. Three pilot zones along the Spanish coast have been chosen for testing the method: San Vicente de la Barquera estuary (N Spain), Guadiana estuary (SW Spain) and Ebro River delta mouth (E Spain). They present different oceanographic and geomorphological conditions. The results obtained have proven that EstuarIndex is a suitable methodology for the application to other estuaries. The systematic application of EstuarIndex on broad time scales would allow evaluating the system trends, what seems key for implementation of more realistic restoration strategies and may help in the detection of the most relevant site-specific vulnerabilities for long-term sustainability in response to both natural and artificial forces.

Published: December 2022

Mine water can be a renewable and economical source of geothermal and hydraulic energy. Nine discharges from closed and flooded coal mines in the Laciana Valley (León, NW Spain) have been studied. Various technologies for the energy use of mine water, as well as the influence of factors such as temperature, the need for water treatment, investment, potential customers and expansion capacity, have been evaluated by means of a decision-making tool. It was concluded that the most advantageous option is an open-loop geothermal system using the waters of a mountain mine, the temperature of which exceeds 14ºC and whose distance to customers is less than 2 km. A district heating has been designed to supply, with technical-economic viability, heating and hot water to six public buildings in the nearby town of Villablino. The proposed use of mine water might help areas that have been greatly affected socio-economically by the closure of the mines and has other intangible advantages compared to conventional systems, such as the reduction of CO2emissions.

Published: December 2022

Image as an essential carrier of data transmission, more and more people pay attention to its security. Although researchers have developed many encryption methods to enhance image transmission security, some have problems such as poor security, long-time complexity, and complicated algorithms. Therefore, this paper proposes a simple and secure encryption method. This method mainly combines chaotic systems with a three-dimensional(3D) linear function iterative system to encrypt images. First, a new chaotic system of 3D linear function iterations is constructed. Then, multiple 3D linear function iterative systems are invoked according to the sequences generated by the disorganized system iteration; finally, the chaotic lines generated by the 3D linear function iteration are operated with color images and gray images, respectively, by dissimilarity. The experimental results show that the scheme has a simple and efficient, low computational cost, good encryption effect, difficult to decipher, and strong key sensitivity encryption effect.
Variational Quantum Search with Exponential Speedup
Authors: Zhan Junpeng
Published: December 2022

With powerful quantum computers already built1,2, we need more efficient quantum algorithms to achieve quantum supremacy over classical computers in the noisy intermediate-scale quantum (NISQ) era2,3. Grover's search algorithm4,5 and its generalization, quantum amplitude amplification6, provide quadratic speedup in solving many important scientific problems7. However, they still have exponential time complexity as the depths of their quantum circuits increase exponentially with the number of qubits6,7. To address this problem, we propose a new algorithm, Variational Quantum Search (VQS), which is based on the celebrated variational quantum algorithms8,9 and includes a parameterized quantum circuit, known as Ansatz. We show that a depth-10 Ansatz can amplify the total probability of k (k≥1) good elements, out of 2n elements represented by n+1 qubits, from k/2n to nearly 1, as verified for n up to 26, and that the maximum depth of quantum circuits in the VQS increases linearly with the number of qubits. We demonstrate that a depth-56 circuit in VQS can replace a depth-270,989 circuit in Grover's algorithm, and thus VQS is more suitable for NISQ computers. We envisage our VQS could exponentially speed up the solutions to many important problems, including the NP-complete problems, which is widely considered impossible.
Assessing the Reliability of Macro Data Using Night-time Lights Models: Bangladesh
Authors: Tahsin Mariha
Published: December 2022

The GDP per capita of 171 countries is estimated using a robust fixed-effects model taking night-time lights as a regressor, for the 1992 to 2020 period. Predicted log transformed GDP per capita values were within 18 percent of the true values for approximately 88 percent of the countries. However, 21 countries; all of whom were weak in terms statistical capacity and economic development; had mean residuals exceeding 18 percent. Bangladesh was one of these 21 countries. The mean log transformed per capita GDP estimated by the model, for Bangladesh, was between 9.16 and 9.23 per year. The government reported value was only 7.68. However, the annual per capita growth rate has been overestimated in recent years, thus, the true and predicted values appear to be converging over time. The differences are most likely a result of the large informal economy that is gradually being factored into GDP calculations.

Published: December 2022

The paper proposes a model for quantitatively analyzing the link between Privacy, Usability, Government Support, Perceived Ease of Use, Perceived Usefulness, Intention to Use and Commitment in the online banking context in Pakistan. In Pakistan (comparing to the size of bank accounts open), few people benefit from online banking and prefer the physical approach. This study analyzes how conventional banking users can be converted to online users, thus reducing the crowds at banks for menial tasks, giving banks more time to focus on corporate clients. For this purpose, an online survey was distributed via social messengers and websites. Out of the collected data, 310 normalized samples were analyzed using correlation and multiple linear regressions. The findings showed that except “Privacy”, “Usability” and “Government Support” had a relationship with “Perceived Ease of Use” where “Privacy” showed no significant impact. “Privacy” had a significant relationship with “Perceived Usefulness”, as did “Perceived Ease of Use”, and “Perceived Usefulness” and “Perceived Ease of Use” had a significant relationship with “Intention to Use”; “Intention” also had a significant relationship with “Commitment to Use Online Banking”. Thus, it is concluded that banks need to realize that bank customers require ease of access and use in order to successfully adapt to the use of online banking, despite the users not being very cautious about online privacy that banks require to ensure on their end, regardless of the user’s thought process.

Liability for assistance to aggressor state: issues of qualification and improvement of criminal law
Authors: Dudorov Oleksandr Oleksiiovych , Movchan Roman Oleksandrovych
Published: December 2022

From the moment of the open attack by the Russian Federation, the issues of criminal law response to encroachments on the foundations of Ukraine’s national security, which have not been resolved since the beginning of the war in 2014, have reemerged. Among the most urgent was the question of whether provisions of criminal law in force as of February 24, 2022 ensured the possibility of providing a proper assessment of the actions of persons who in various forms assist the aggressor state. The first decision made in order to solve this issue was the introduction of Article 111-1 “Collaborative activity” to the Criminal Code of Ukraine. Due to the belief of the People’s Deputies of Ukraine in the inadequacy of such a legislative step, another criminal law prohibition has appeared – Art. 111-2 “Assistance to the aggressor state”.

The purpose of the research is in critical understanding of the debatable aspects of the criminal law novel about aiding the aggressor state, based on the results of which scientifically based recommendations should be developed in order to improve relevant provisions of the current criminal law and practice of its application.

It has been proven that, despite the noble intentions of the parliamentarians, the inclusion of Art. 111-2 “Assistance to the aggressor state” has increased both the conflicting nature of the domestic criminal law and the legal uncertainty partially inherent in it, and also forces us to once again talk about excessive criminalization. Among the achievements of the legislative work related to the construction of the criminal law prohibition dedicated to aiding the aggressor state, one can only include the non-use in the current wording of Art. 111-2 of the Criminal Code of unjustifiably abstract phrases “other voluntary interaction with representatives of the aggressor state” and “any cooperation with representatives of the aggressor state”.

Based on the example of criminal law assessment of such manifestations of assistance to the aggressor state, such as the transfer of material resources to the armed formations of the aggressor state and the implementation or support of the decisions and / or actions of the aggressor state, armed formations and / or the occupation administration of the aggressor state, the problematic nature of differing analyzed crime from collaborative activity, treason and justification, recognition as legitimate, denial of armed aggression of the Russian Federation against Ukraine, glorification of its participants has been demonstrated. The problem, which has risen as a result of the partially inappropriate duplication of legislative material, is proposed to be solved in one of three ways to optimize the articles of the Criminal Code on liability for treason, collaborative activity and assistance to the aggressor state.

A hulladék a fogyasztói társadalom „terméke”. A kommunális hulladék a teljes hulladék (ami EU-s szinten évente 2,5 milliárd tonna) 8,2%-át teszi ki (europarl.europa.eu). A hulladék mennyiségének növekedése veszélyezteti nemcsak a természeti, de a társadalmi környezetet, valamint a fenntarthatóságot is, így törekedni kell a hulladék mennyiségének csökkentésére. A lakosság körében ennek alapja a szelektív hulladékgyűjtés, ami a hulladék újrahasznosításával csökkenti a pazarló anyag- és energiafelhasználást, hozzájárul a környezetvédelemhez és a körkörös gazdaság kialakulásához.Kutatásunk célja, hogy feltérképezzük Győr-Moson-Sopron megyében a lakosság szelektív hulladékgyűjtéssel kapcsolatos attitűdjét, a meghatározó tényezőket, a szelektíven gyűjtött hulladékok fajtáit, külön vizsgálva az egyes hulladéktípusok lakossági gyűjtési technikáit, valamint a lakosság újrahasznosítási hajlandóságát.
Economic disruption as a strategic accelerator: the increased importance of Strategic Alignment in the post-Covid-strategy
Authors: Schmude Thorsten
Published: December 2022

Nobody was prepared for such a health crisis: it was January 2020 when the Covid-19 pandemic broke out, and within a matter of weeks its effects could be felt the world over. Suddenly, to stave off a complete collapse of the economy, entire industries became dependent on financial state aid. The pandemic represents the first global health crisis experienced by our generation–entailing economic disruption of the global economy and all businesses. Disruption (= drastic destructive change) can result in risks as well as opportunities. Weak business models that had already ignored important developments before the crisis quickly became obsolete, and rapid adaptability and orientation to economic conditions became important for survival. Focusing on new strategic options has therefore become much more urgent and this will remain so. Indeed, Strategic Alignment as a core aspect of strategy execution is now more important than ever. Wasting time, financial and human resources can only be avoided by a close commitment to the adopted strategy. The alignment of the business operation with all its aspects is the research domain for this qualitative study. The research design is based on the Grounded Theory Methodology (GTM), which makes a strategic topic well accessible through iterative research cycles.

Published: December 2022

A tanulmány témája a környezet- és egészségtudatosság tényezőinek hatása a kozmetikumvásárlási és -fogyasztási döntésekre. A téma jelentősége abban rejlik, hogy a kozmetikai ipar folyamatos „zöldülése” által a vásárlók egyre szélesebb szortimentű kozmetikai termékpalettából válogathatnak, amely, mind a Föld egészségére, mind az azt vásárló fogyasztók egészségi állapotára kedvező hatást gyakorol. A tanulmány célja annak a vizsgálata, hogy a fogyasztók/vásárlók milyen tényezők hatására hoznak döntést a környezet- és egészségtudatos kozmetikai termékek megvásárlása és használata mellett, és ezek alapján ezen kozmetikai termékek vásárlói és fogyasztói hogyan szegmentálhatók. A kutatás módszertanát tekintve kvantitatív kutatás, formája online megkérdezés (n=1.439). Elvárt eredményekként kerül bemutatásra egy saját elméleti és egy saját kutatási modell, illetve a két modell közötti kapcsolat, továbbá a környezet- és egészségtudatos kozmetikumok igénybevételére ható faktorok és klaszterek.

A pénzügyi kultúra, pénzügyi tudatosság, öngondoskodás témakörei egymásra épülő ismeretek, amelyek ismerete vagy az ismeret hiánya jelentősen befolyásolja a társadalom szereplőinek gazdasági jellemzőit, pénzügyi hátterét, anyagi biztonságát. A pénzügyi kultúra, a tudatos pénzügyi gondolkodás, a jövőbe tekintő öngondoskodás korosztályonként eltérő jellegű lehet, de elmondható, hogy a fejlődés bármely életszakaszban megtörténhet. A legcélszerűbb természetesen az lenne, hogy már iskolás korban megkezdődjön az edukáció, hogy a felnőttkorba lépők már tudatosan építhessék fel életük biztos pénzügyi alapjait. Kutatásunk a középiskolai korosztály pénzügyi kultúrával és öngondoskodással kapcsolatos ismereteire fókuszált, kérdőíves megkérdezés alkalmazásával, mely során 811, különböző iskolatípusokban tanuló középiskolástól kaptunk értékelhető válaszokat. Eredményeink rámutatnak arra, hogy mivel az iskoláknak jelenleg nincsenek egységes koncepcióik az ismeretek oktatására és a tantervek, szakképzési programtervek nem tartalmaznak tananyagot pénzügyi ismeretek oktatásához célszerű lenne ezt a témakört is az oktatásba bevonni.
Effects of boiling on iron particles in drinking water

Published: December 2022

Discoloration events in drinking water distribution systems (DWDSs) caused by iron particles have occurred worldwide, and boiling has been applied in drinking water treatment households globally, but the effects of boiling on iron particles are not clear. Here, the effect of boiling on different kinds of iron particles (including loose deposits from the DWDS and their main components FeOOH, Fe2O3, and Fe3O4) was studied. At 10 mg/L, the turbidity values before/after boiling of Fe2O3, Fe3O4, and FeOOH were 134.00/121.00, 25.07/21.22, and 120.40/114.20 NTU, respectively. All the particles had a lower degree of crystallinity after boiling. After boiling, the number of particles in loose deposits increased and the particle size decreased, while iron oxides were on the contrary. Among the three iron oxides, the existence of Fe3O4 and Fe2O3 had different effects on disinfection by-products (DBPs) formation. The activity of microorganisms was the highest under particle concentration of 0.1 mg/L than other concentrations for all the particles, but the total microbiological risks were still very low after boiling. Thus, the boiling treatment would increase the turbidity and risks of the particles. As the particle concentration under low concentration is hard to find, this risk is also hard to find.
Study of natural oscillations of oil in a vertical well
Authors:   Mavlyutov Institute of Mechanics, UFRC RAS, Ufa, Russia, Mamaeva Z.Z. , Rafikova G.R.
Published: December 2022

In the oil industry, an important aspect in the production of hydrocarbons is the control of the state of the well and the study of the near-wellbore zone adjacent to it. For this purpose, various geophysical well survey methods (GIS) are used. One of the methods of well logging is acoustic spectroscopy of wells, where the characteristics of the well and reservoir can be studied by means of excitation of natural oscillations of the fluid. In this paper, the problem of natural oscillations of a fluid in a vertical well, which arose as a result of a sharp opening or closing of the well, is investigated. To describe this process, a mathematical model of natural oscillations of the liquid column in the well, which communicates with the reservoir through the permeable walls of the open area, is constructed using the mass and momentum conservation equation in the well area, the mass conservation equation in the open area of ??the well, and the filtration equation in the reservoir. Taking into account the initial and boundary conditions, an analytical solution was found in the form of standing waves to determine the pressure and velocity of oil in the well. The dependences of the oscillation frequency, decrement and damping factor on the reservoir permeability are shown, the pressure dynamics in the well is given and the amplitude of the oscillations is considered. A comparative analysis of changes in such indicators as oscillation frequency, decrement and damping coefficient has been carried out. The influence of such parameters as the length of the bottomhole zone and the permeability coefficient on the nature of the change in the natural fluctuations of the fluid has been established.
Pressure waves in a tube filled with a liquid with a bubble region in it in the form of a torus
Authors:   Mavlyutov Institute of Mechanics UFRC RAS, Ufa, Russia, Galimzyanov M.N.
Published: December 2022

Problems considering the focusing of wave energy in a liquid are related to the problem of making hydroacoustic analogs of laser systems that could absorb an external action and re-emit it with a significant increase in amplitude and energy concentration in an adjusted direction. In this paper, we study two-dimensional axisymmetric wave perturbations in a channel with water containing a toroidal coaxial cluster filled with a water-air bubble mixture. Based on the results of numerical calculations, the dependence of the maximum pressure amplitude formed in the channel on the geometric parameters of the cluster and channel, as well as on the amplitude of the initial impact, is analyzed. It has been established that in the case of a cylindrical cluster the amplitude of the wave signal behind the bubble zone is several times higher than the amplitude for the case of a cylindrical toroidal cluster.
Application of free software to visualize the results of simulation of dynamic processes
Authors:   Mavlyutov Institute of Mechanics, UFRC RAS, Ufa, Russia, Nasibullayev I.Sh.
Published: December 2022

The paper presents an overview of modern free tools for dynamic visualization and gives recommendations for choosing tools depending on the research method, the form of presentation of the initial data, and the specifics of the phenomenon under study. For the convenience of using the materials of the work, the source codes are given both for the programs of computational experiments of classical problems, and for creating a graphical visualization of the simulation results. To animate the process described by analytical formulas, it is proposed to use the gif terminal of the gnuplot program or the Python visualization library. An example of applying this approach to solving the modified Verhulst-Pearl equation, which describes the change in the population under periodic external influence, is given. When studying non-stationary phenomena distributed in space, the results can be presented in video format. The problem of natural convection in a horizontal layer of fluid or gas was simulated in the program FreeFem++ for solving differential equations by the finite element method with the conversion of the results using the GhostScript and MEncoder programs into a video format. An example of using the finite difference method in modeling self-oscillating chemical reactions in the Qt environment with saving animation frames as graphic files is given. To display the results of modeling three-dimensional dynamic processes, it is proposed to use the Blender computer graphics program. Modeling and visualization of oscillations of an elastic pendulum using the built-in Blender Python API interpreter are presented. An approach is shown for dividing a computational experiment and visualizing its results, which makes it possible to increase the efficiency of the use of computational resources. A universal Python-script is proposed for constructing three-dimensional object motion trajectories based on external source data.

Determining Counseling Self-efficacy of Indian Students of Speech Language Pathology
Authors: Shwetha Nambiar , Megha Mohan , Sudhin Karuppali
Published: December 2022

Purpose:

Counseling self-efficacy is the view that counselors have of their capability to practice certain abilities that contribute to good clinical service. Speech Language Pathologists (SLPs) require to possess strategic counseling skills for effective service delivery. Although counseling is mostly considered an essential component during rehabilitation, many SLPs receive no explicit training on the same. The current study aims to explore self-efficacy measures in counseling among Indian students of speech-language pathology.

Methods:

The Counselor Activity Self-Efficacy Scales (CASES), which is a 6-point Likert rating scale developed by Victorino and Hinkle (2019) was adopted to assess the self-efficacy of 105 student clinicians (undergraduates and graduates) of speech-language pathology. The study comprised of two phases. Phase one included the administration of the CASES questionnaire on the target population, and Phase two included performing frequency-based analysis on Helping Skills (HS), Emotional Support Skills (ESS), and Session Management Skills (SMS) domains.

Results:

The majority of participants felt somewhat confident over questions in the HS and ESS domain, while a large proportion felt very confident over the questions in the SMS domain. Although the student clinicians felt somewhat confident and very confident in most of the domains, none of the participants were completely confident in any of the domains.

Conclusion:

Having a counseling self-efficacy tool will help estimate the level of counseling competency one may possess. The results of the study can be used to design effective counseling-based training programs for student clinicians and practicing professionals, to achieve productive therapeutic connections with patients and caregivers.
Perencanaan Rancang Bangun Microstrip Band Pass Filter dengan Struktur Tapped Input Hairpin pada Aplikasi Jaringan Mid-band 5G Telkomsel
Authors: Prijono Wahju Adi , Rizki Naufal Kurnia
Published: December 2022

Microstrip filter is a type of Radio Frequency (RF) filter that uses a thin electrical conductor separated from the ground plane by using a dielectric called the substrate. Microstrip filters are generally printed on Printed Circuit Boards or PCBs where high-frequency signals are directed from one part of the system to another with high efficiency. There are several types that can be applied to the operation of microstrip filters, one of which is a band pass filter. Band pass filter is a filter that can pass a signal with a certain frequency that is limited by a low cut-off frequency and a high cut-off frequency, and is able to dampen signals that are below the cut-off frequency and above the high cut-off frequency. There are several types of resonator designs that can be used for reference in the manufacture of microstrip filters, such as tapped line input hairpin filters, stub loaded filters, stepped impedance filters, and combline filters. By using the reference form of the tapped line input hairpin, this journal is intended for planning the manufacture of microstrip filters in the application of Telkomsel's 5G technology.

The stepwise method is chosen in order to check the correlation between the rainfall data and debit data based on multi-correlated statistics and the WMO guidance are used to complete the minimum requirement of the number of rainfall stations in a watershed according to geographical aspects. It was found that the Telomoyo watershed has met the minimum WMO standards, namely with 9 rainfall stations, but it is still considered irrational due to the uneven distribution of rainfall station as seen from the range of influence in each rainfall station. Meanwhile, from the stepwise analysis, it is found that the combination of 4 rainfall stations is considered rational and meets WMO standards. However, this study only provides recommendations for the most statistically rational rainfall station combinations. It is also permissible to move or choose another rainfall station that has more strategic locations so that the influence area of the rainfall stations is more evenly distributed.Â DAS Telomoyo memiliki luas sebesar 553,22 km2 dan termasuk dalam kategori daerah pegunungan serta dataran tropis. Dalam pemenuhan akan kebutuhan infrastruktur bangunan air yang memadai, diperlukan data hujan dengan kualitas baik yang salah satu caranya yaitu melihat keterkaitan data hujan yang ada dengan data debit yang didapatkan di lapangan. Metode yang dapat digunakan adalah rasionalisasi metode stepwise dan evaluasi berdasarkan standar WMO. Metode stepwise dipilih untuk mengecek korelasi data hujan dengan data debit berdasarkan statistika multi korelasi dan standar WMO digunakan untuk melengkapi ketentuan minimum dari jumlah pos hujan suatu DAS menurut aspek geografi. Didapatkan bahwa DAS Telomoyo sudah memenuhi standar minimum WMO yaitu dengan 9 stasiun curah hujan serta 2 AWLR, namun hal ini masih dirasa belum rasional karena persebaran pos hujan yang kurang merata yang menurut luas pengaruh area setiap stasiun curah huan. Sedangkan dari analisis stepwise diperoleh bahwa gabungan 4 pos hujan sudah rasional serta memenuhi standar WMO. Namun studi ini hanya memberikan rekomendasi kombinasi pos hujan yang paling rasional secara statistik. Diperbolehkan juga melakukan pemindahan atau pemilihan pos lain yang memiliki lokasi lebih strategis sehingga luas pengaruh pos hujan lebih merata lagi.
