Optimal Design of Supply-Adequate Microgrids in a Multi-Carrier Energy System
Authors: Daryani Narges , Zare Kazem , Tohidi Sajjad , Guerrero Josep
Published: January 2023

Energy hubs by interconnecting various energy systems give rise to the
multi carrier energy (MCE) system, as the upcoming energy providing
system. The appropriate design and operation of microgrids (MGs) are
essential in the MCE systems. In this paper, the self-adequacy
improvement of MG within an MCE system is got under studied while
achieving an optimal design for MGs. It is considered that the
constructed MGs operate in both grid-connected and islanded modes. In
other words, separating the designed zones leads to independent
performance of the MGs which give more importance to the supply-adequacy
context. Implementing the mentioned problem to real systems leads to a
large scale, nonlinear problem which should be optimized using the
robust optimization techniques. A modified version of group search
optimization (GSO) algorithm is utilized in order to solve such problem.
In order to obtain reasonable results and perform analytical
evaluations, some efficient indices are proposed. Afterwards, the
proposed scheme is applied to an 11-hubs test system and the obtained
results are analyzed and discussed.
The near-hand effect on the visual processing of objects in a sample of right-handed, normal vision adults
Authors: Gaiera Francesca
Published: January 2023

Past studies have evinced that the perception of near-hand objects is
qualitatively different from that of far-hand objects. However, as the
influence of test anxiety during tasks of visual processing has never
been considered, this study aims to assess whether the presence of hand
alters/biases the visual processing of objects while controlling for the
effect of test anxiety. A sample of 30 participants aged 22-55 years old
was recruited through convenience sampling and performed a cognitive
task based on the Posner paradigm of Inhibition of Return (Posner et
al., 1985) during which they held their hand on their lap in the control
condition and next to the screen in the experimental one. Their test
anxiety was assessed retroactively through the Test Anxiety Profile
(Oetting & Deffenbacher, 1980, as cited in Gass and Curiel, 2011). A
correlation was performed between test anxiety and Reactions Times (RTs)
scores, and an analysis of variance was computed with the presence of
the hand and the validity of trials as independent variables and RTs as
the dependent variable. Next, an analysis of covariance included test
anxiety as the covariate. The presence of the hand altered/biased the
visual processing of stimuli, and participants shifted their attention
between items faster in the experimental condition. Participants’ test
anxiety did not mediate the near-hand effect. This study provides
insights into the development of multitouch devices and their
applications in the educational setting.
Narrow Therapeutic Index (NTI) Drugs: Definitions and Criteria
Authors: Habet Sam
Published: January 2023

Purpose: Narrow therapeutic index (NTI) drugs must be routinely
monitored for their severe effects. These drugs share some common
features and criteria that focus on the separation of safety and
efficacy in relation to toxicity and efficacy. Methods: There are many
factors that contribute to drugs’ high toxicity and lack of efficacy,
including the following 5: right drug, right dose, right time, right
duration, right age. Results: It’s reviewed over 200 drugs, focusing on
NTI drugs’ clinical pharmacology, dose-response relationship,
physiochemical properties, and potential drug-drug interactions. It is
found that any minor change in therapeutic drug concentrations or doses
may have significant consequences for patients, such as bleeding due to
warfarin overdose or thrombotic events due to underdose. Conclusions:
For NTI drugs, therapeutic drug monitoring (TDM) must be accessible in
all hospitals and outpatient clinics to ensure patient safety. These
approaches and methods must be done in each patient.
Escalated fungal spores and its consequences on asthma: the aftermath of recent torrential downpour
Authors: Shabbir Noor Zehra , Rahim Tanisha , Asad Syed Ahmed , Baig Mirza Ahmed , Abbas Munib , Taseen Shafaq
Published: January 2023

The increase in asthma cases in Pakistan after the flood of 2022 has
confirmed that the condition is a serious public health hazard. The
production of fungus spores on moist surfaces and in humid environments
is a significant factor in asthma onset. In this study, we discuss the
distinctive seasonality and mechanism of fungal spore occurrence in
Pakistan. Epidemic areas are those that are characterized by
intermittent outbreaks, are close to local rivers, or have humid
environments that are conducive to the formation of molds and fungus
spores. Heavy rain promotes the interaction between contaminated water
and human activity, which can lead to an increase in sporogenesis which
is directly linked to a number of asthmatic patients. We studied the
association between exposure to pluvial floodwater, production of fungal
spores, and its impact on the respiratory condition “Asthma”
The impact of zooplankton calcifiers on the marine carbon cycle

Published: January 2023

Shelled pteropods and planktic foraminifers are calcifying zooplankton
that contribute to the biological carbon pump, but their importance for
regional and global plankton biomass and carbon fluxes is not well
understood. Here, we modelled global annual patterns of pteropod and
foraminifer total carbon (TC) biomass and total inorganic carbon (TIC)
export fluxes over the top 200m using an ensemble of five species
distribution models (SDMs). An exhaustive newly assembled dataset of
zooplankton abundance observations was used to estimate the biomass of
both plankton groups. With the SDM ensemble we modeled global TC biomass
depending on multiple environmental parameters. We found hotspots of
mean annual pteropod biomass in the high Northern latitudes and the
global upwelling systems, and in the high latitudes of both hemispheres
and the tropics for foraminifers. This largely agrees with previously
observed distributions. For the biomass of both groups, surface
temperature is the strongest environmental correlate, followed by
chlorophyll-a. We found mean annual standing stocks of 52 (48-57) Tg TC
and 0.9 (0.6-1.1) Tg TC for pteropods and foraminifers, respectively.
This translates to mean annual TIC fluxes of 14 (9-22) Tg TIC yr-1 for
pteropod shells and 11 (3-27) Tg TIC yr-1 for foraminifer tests. These
results are similar to previous estimates for foraminifers standing
stocks and fluxes but approximately a factor of ten lower for pteropods.
The two zooplankton calcifiers contribute approximately 1.5% each to
global surface carbonate fluxes, leaving 40%-60% of the global
carbonate fluxes unaccounted for. We make suggestions how to close this
gap.

Published: January 2023

The purpose of this study was to verify the item quality, validity, and reliability of the assessment tool for diagnosing the digital competence for early childhood teachers. To this end, a Google survey was conducted on 250 teachers working in kindergartens and daycare centers in Seoul, Incheon, Gyeonggi, and Chungcheong. The research results are as follows: First, as a result of analyzing the item quality, it was found that the item average did not have an excessively low average, so the difficulty was not high, and there were no items with an excessively small standard deviation.
Skewness and kurtosis met the criteria and assumed normality. Second, as a result of performing exploratory urine analysis to analyze construct validity, confirmatory factor analysis was performed with 28 competencies of 7 factors, excluding 4 items that were not suitable for factors. As a result, RMSEA, RMR, CFI, TLI, and IFI all met the acceptance criteria, so the model was fit. On the other hand, the standardized estimation coefficient for convergent validity, C.R. All of the values exceeded the acceptance criteria, and both the conceptual reliability and mean variance extract for each factor were more than the acceptance criteria. In addition, as a result of verifying the reliability of each factor, the reliability was found to be high, with Cronbach's α .89 to .94. Finally, 28 evaluation items with 7 factors were derived through validation and reliability of the digital competence assessment tool for early childhood teachers. Therefore, it is expected that it can be used as basic data to compose the contents of teacher education to strengthen digital competence.
Microwave-assisted synthesis of a series of 4,5-dihydro-1H-pyrazoles endowed with selective COX-1 inhibitory potency
Authors: Altintop Mehlika , Temel Halide , Özdemir Ahmet
Published: January 2023

Considerable efforts have been directed towards the discovery of selective cyclooxygenase isoxyme 1 (COX-1) inhibitors due to the recent work highlighting the involvement of COX-1 in the pathogenesis of pain, neuroinflammation, cancer and cardiovascular disorders. In this context, this paper aims to describe 2-pyrazolines endowed with selective COX-1 inhibitory potency. An efficient microwave-assisted synthetic method was applied for the preparation of a series of pyrazolines, which were tested for their COX-1 and cyclooxygenase isoxyme 2 (COX-2) inhibitory effects using a colorimetric assay. The cytotoxic properties of the most potent derivatives on NIH/3T3 fibroblast cells were determined using MTT method. 1-(3-Fluorophenyl)-5-(3,4-methylendioxyphenyl)- 3-(2-thienyl)-4,5-dihydro-1H-pyrazole (2g) and 1-(3-bromophenyl)- 5-(3,4-methylendioxyphenyl)-3-(2-thienyl)-4,5-dihydro-1H-pyrazole (2h) were determined as selective COX-1 inhibitors. According to the in silico data obtained from Schr?dinger?s QikProp module, both compounds are estimated to possess favourable oral bioavailability and drug-likeness. This work could be a rational guideline for further modifications at different sites on 2-pyrazoline motif to bring out a new class of selective COX-1 inhibitors.

GEODYNAMICS
Authors:   Carpathian Branch of Subbotin Institute of Geophysics of the NAS of Ukraine, Gnyp Andriy
Published: January 2023

The differential and source terms locations of a series of small (1.0<ML<2.5) similar (recurrent) earthquakes that occurred during 2013-2015 near the village of Trosnyk in the south of Transcarpathians were determined. Adaptive filtering was proposed to reduce the effect of correlated noise in records with very low signal-to-noise ratio and to improve the reliability of differential arrivals. The maximum correlation criterion was modified to include the minimum departure from the calculated arrival times. Analysis of the intervals between phase arrivals at pairs of stations was proposed to further reduce the number of problematic arrivals. The sensitivity of the final solution to the network configuration was assessed using the jack-knife principle, when the coordinates are calculated, each time removing one station from the full set. The focal mechanism common to all earthquakes in the series was defined using the polarities of P-wave arrivals at 16 stations. Based on the results of the 3D interpretation of the differential hypocenters, the nodal plane with a strike of 150° was identified as the rupture plane, and the mechanism itself was classified as left-lateral slip with a component of thrust. The epicenter of the strongest earthquake was located almost exactly on the fault of the pre-Neogene basement with a strike parallel to the Carpathian arc, almost the same as the strike of the rupture plane. The axis of compression in the focal mechanism is directed to the east, which is fully consistent with the northeast direction of the general regional field.

Understanding of IoT and Awareness of IoT Education Among Elementary School Pre-service Teacher
Authors:   The Korean Association of Practical Arts Education, Kang Jong Pyo
Published: January 2023

To obtain basic information for Internet of Things (IoT) education in future elementary schools, this study analyzed a sample of pre-service teachers to determine their degree of understanding of IoT. As such, they were allowed to directly configure and experience the operation of an IoT device. Points of focus included the appropriateness of the developed device, prospects for IoT education in elementary school, and perceptions on suitable devices and contents. The results were as follows.
First, the participants had a low understanding of IoT itself and were not well-acquainted with IoT device composition or the operation process. While they did not have much experience applying IoT in daily life, they were highly motivated to learn about IoT devices. This highlights the need to provide structured opportunities for teaching, learning, and experience.
Second, the participants said that their understanding of IoT had improved after directly configuring and experiencing the operation of the IoT device. In this case, they were able to understand the operation process pertaining to the parts constituting IoT and the field of application of IoT in daily life.
Third, the participants predicted that IoT would increasingly be applied in daily life and appear as a component in future elementary education curricula. The participants said that elementary IoT education should include programming for IoT operation, which should be supported through direct IoT device configuration.
Fourth, given that IoT-related contents are introduced into elementary education curricula, students should be able to experience those contents in daily life, with practical examples provided to enhance their understanding.
Fifth, in relation to IoT operation, the WiFi module method was deemed appropriate for efficient teaching and learning, as compared to the Bluetooth module method.

This study was analyzed qualitatively. The data of this study is the clause that consists of modality on President Trump’s speech, and sources of data is taken from www.nytimes.com. The data collected by applying a documentary technique. The finding reveals that the speakers use modalization of probability in their speech. The use of modality realized by modal auxiliary that commonly used by the speaker in the speech is sub modalization–probability. The reason that the speakers use modality is typically the modalization used to convey/persuade the listener of the speaker talk about the future political event that have not happened yet and unpredictable things.
Impact of European structural and investment funds absorption on the regional development in the EU-12 (new member states)
Authors: Vukašina Martina , Kersan-Škabić Ines , Orlić Edvard
Published: January 2023

Research background: European Structural and Investment Funds (ESIF) as the main instruments of cohesion policy (CP) in the EU, provide a broad source of financing opportunities for the EU member states. The biggest amount in the CP budget is oriented to convergence NUTS 2 regions that have GDP p.c. below 75% of the EU average. The new members of the EU (accessed in 2004 and 2007) had available 176.3 billion EUR in the period 2007?2013 and 217 billion EUR in the period 2014?2020. Even the absorption rate (in 2007?2013) of available ESIFs is high (above 90%), the real implications on their economies don?t come automatically and they represent the area for examination.
Purpose of the article: The research aims to analyse the impact of ESIFs absorption in EU new member states in the period 2008?2016 on their GDP p.c. 
Methods: As the sample has time and cross-sectional dimension, the panel data in static and dynamic form is employed. The analysis covers the major part of the financial framework 2007?2013 and a part of financial perspective 2014?2020 (depending on the available data).
Findings & value added: The results indicate that increase in ESIF p.c. for 1% will contribute to the GDP p.c. increase for 0.0053 to 0.0064 % (static model) and for 0.008% (dynamic model). Although the impact of ESIFs is significant and positive, it is quite (and unexpectedly) small, and consequently new EU member states should not rely too much on them as the source of economic progress. It is necessary that countries should focus on channeling funds into specific segments (sectors, policies) that will result in increased competitiveness of their economies. The contributions lie in creating GDP p.c. determination function; in including all new EU member states; in including more recent available data and by observing ESIFs as a part of growth model.
Selected Rescue Problems including means of transport during Pandemic of the Covid-19
Authors: Nowacki Gabriel , Krawczyk Mateusz
Published: January 2023

The work concerns selected rescue problems, including the handling of the 112 emergency number during the Covid-19 pandemic in Poland. The 112 number is valid throughout the EU, it is used only to notify in emergency situations of threat to health, life, or property. As social practice shows, disruptions in its functioning, including unjustified reports, significantly increase the costs of its operation, and in extreme cases may lead to failure to provide assistance to those in need. The ongoing pandemic has left a significant mark on many aspects of life, including the operation of rescue systems responsible for the safety of citizens in the country. The co-author of the work during the service of the 112 emergency number noticed some problems and disadvantages related to the rescue operation in crisis management. This was the reason for presenting this issue in the form of a publication. Selective problems of rescue in crisis management related to the ongoing pandemic were indicated.

Authors:   Hebei University of Technology, Li Zenong
Published: January 2023

High-frequency transformers (HFTs) are the indispensable component in isolated high-power dc-dc converters which have been the basic building blocks for solid-state transformers. To ensure high efficiency, high power density and high reliability, careful selection, design, modeling and evaluation are necessary for the magnetic core of an HFT. However, due to the nonlinear characteristics and the complex physical mechanism, magnetic cores have always been regarded as the focus and difficulty. This paper systematically reviews magnetic core materials commonly used in HFTs, core loss modeling methods based on classical Steinmetz equation (SE), and advanced core loss measurement techniques. Pros and cons for the magnetic materials, modeling and measurement methods are comprehensively analyzed and summarized to provide a sufficient application insight.

Authors:   Fuzhou University, Chen Qingbin
Published: January 2023

The integrated magnetics technology is famous in academic and industrial applications to achieve low profile and high power density of switch-mode power supply (SMPS). The integrated LLC transformer is widely used in LLC converter, where the transformer and resonant inductor are integrated into a magnetic component. However, the value Variation range of leakage inductance of conventional integrated transformer structures is limited due to the low profile and small volume in some planar applications. In this paper, a new integrated LLC transformer structure and its leakage inductance adjustment method are proposed. Based on the two-dimensional equivalent model of the structure, the distribution of the leakage magnetic field and the leakage inductance calculation model of the proposed transformer structure are established. The proposed structure can improve the value variation range of leakage inductance in some special applications and is easily achieved in the planner structure. Finally, the design guideline of the proposed integrated LLC transformer is obtained. Simulation results and prototype experiment results verify the correctness and flexibility of the theoretical analysis.
Multi-resonant DC-DC Converter Based on Switched Capacitor Pre-voltage Reduction
Authors:   Harbin Institute of Technology, Guo Qi
Published: January 2023

This paper proposes a multi-resonant DC-DC converter based on switched capacitor pre-buck. The converter can realize soft switching in the full load range and has good voltage gain characteristics. In order to effectively reduce the voltage stress on the device, the front stage of the converter adopts a stacked structure of switched capacitors. This structure realizes the function of high step-down ratio by pre-stepping the bus voltage. After reasonable parameter design and frequency matching, the third harmonic is superimposed on the high-order resonant link of the latter stage during the energy transmission process. This will significantly reduce the loss of the secondary side rectifier diode and increase the efficiency. This paper introduces the working principle of the converter, proposes a five-element parameter design scheme, and analyzes the parameter dispersion to assist the parameter design scheme to make it more reasonable, and finally conducts experimental verification. A 100 W prototype with 400 V input and 12 V output was built in the laboratory to verify the correctness of the theoretical analysis.
Accurate, Fast and Power Efficient PV Emulator Based on Hybrid Passive and Active Circuits
Authors:   University of Technology Sydney, Khawaldeh Habes
Published: January 2023

A photovoltaic emulator (PVE) has been proposed based on a physical equivalent photovoltaic cell model. It has fast dynamic performance that is compatible with a real PV system. The PV emulator can analyze and assess PV systems, including maximum power point tracking (MPPT). It is power efficient at the maximum power point. However, it has higher power loss at an open-circuit voltage (OCV). This paper, therefore, presents a hybrid solution using a switching circuit (SC) paralleled with the diode string (DS) to minimize the power loss. The SC consists of a two-switch non-inverting buck-boost dc/dc converter. The DS operates with a low power loss region, i.e., the current source region (CSR) of the I-V curve, in which the SC switches in to replace the DS in the voltage source region (VSR) to minimize power loss of the DS while maintaining the emulator’s circuit operation. The SC handles only a fraction of the rated emulator power and has a much narrower control bandwidth than a pure switching converter-based solution. Experimental results show that in the worst-case scenario, i.e., OCV condition, the efficiency and temperature of the PVE based on DS alone configuration reach 2.8% and 94.2 °C, respectively, as compared to 85.98% and 26.5 °C for the proposed hybrid solution. Under the 30% to 60% insolation change test, the suggested PV emulator lags the actual PV panel by only 3.2 ms, compared to 120 ms lagging for a commercial emulator. Furthermore, the control strategy is implemented to handle the trade-off between thermal and dynamic performances of the proposed solution.
An Improved Constant Power Generation Algorithm for Photovoltaic Systems
Authors:   Nanjing Normal University, Yang Tangwu
Published: January 2023

High penetration of photovoltaic power generation will bring some new challenges to the grid, such as overvoltage and overload. To address these problems, a constant power generation (CPG) algorithm is proposed. However, the conventional CPG algorithm cannot balance tracking speed and accuracy. Therefore, an improved CPG algorithm with rapid tracking speed and high accuracy is proposed in this paper. Finally, the superiority of the algorithm is verified in simulation and experiments.

Az egyenlőtlenségek csökkentése érdekében az anyagi helyzet mellett a mentális és testi egészség javítása is szükséges. A problémák azonosítása segíthet meghatározni azokat a területeket, melyek fejlesztésre szorulnak a különböző hátrányos helyzetű csoportoknál. Külön figyelmet kell fordítani az egészséges életmódra, a tanulásra és a stresszel való megküzdésre. Ezen célok elérésében fontos szerepet játszanak a társas támogatást is erősítő közösségi egészségfejlesztési programok. A közlemény egy Szabolcs-Szatmár- Bereg megyei járás példáján keresztül ismerteti a hátrányos helyzetű lakosság egészségmagatartására, egészségi állapotára jellemző tényezőket, valamint keresi az ezek javítására szolgáló megoldásokat. Az olvasó megismerkedhet az egészségfejlesztési irodák működésével, céljaival, valamint bemutatásra kerül, milyen szerepet tölthetnek be a hátrányos helyzetűek egészségének megóvásában, egy, a célcsoportnak szóló, Szabolcs-Szatmár-Bereg megyei iroda által megvalósított egészségfejlesztési programon keresztül. Ezen közösségi egészségfejlesztési programok esetében érdemes megjegyezni, hogy bár a rövidebb időtartamon belül megvalósítottak esetében csökken a lemorzsolódás esélye, a hosszabb távú, mélyreható változás eléréséhez intenzívebb programsorozat szükséges.

A fejlett országokban ma is listavezető halálok a szív- és érrendszeri-, valamint a daganatos megbetegedések miatti halálozás. Az utóbbi időben egyre inkább felismerésre kerültek azok az egészségveszteséget okozó, jelentős populációt érintő megbetegedések, melyek elsősorban a lakosság mentális jóllétét határozzák meg. Az egészségügyi alapellátásban dolgozó orvosok korfája alapján várható, hogy a közeljövőben jelentős számú háziorvos kerül inaktív állományba, hiszen a jelenleg praktizáló háziorvosok kétharmada 55 év feletti életkorral rendelkezik. Éppen ezen okok miatt válik elengedhetetlenné a társadalom számára, hogy a prevencióra és az egészségfejlesztésre nagyobb hangsúly helyeződjön. Az Egészségfejlesztési Iroda hálózat létrehozásának egyik kiemelet célja volt, hogy az egészségügyi ellátórendszer – elsősorban - primer prevenciós funkcióit fokozza a tevékenységeivel, továbbá a lakosság egészségtudatosságának növelje a programjaival. Az egészségügyi alapellátásban a népegészségügyi, egészség-központú szemlélet szerepének növeléséhez a szakemberek e területekre vonatkozó ismereteinek, kompetenciáinak növelése is szükséges. Az Egészségfejlesztési Irodák létrehozásának fő célja a lakosság egészségmagatartásának javítása, a születéskor várható élettartam és az egészségben eltöltött életévek számának növelése. További feladat az egészségügyi alapellátásban résztvevők és a civil és egyéb intézmények partnerhálózatban való szervezése, továbbá az alapellátás egyes egészségfejlesztő tevékenységeinek (pl.: egyéni állapotfelmérés) segítése. A Szabolcs Szatmár Bereg Megyei Kórházak és Egyetemi Oktatókórház Egészségfejlesztési Irodái által végzett egyéni állapotfelmérés és tanácsadási feladatok hatékonyságát és a jövőben javítandó részterületek bemutatását célozza az írás.
Development Opportunities for the Accommodation Industry: Evidence from European Countries
Authors: Rohoza Mykola , Stolyarchuk Valentyna
Published: January 2023

This article focuses on the current trends in accommodation industry development in European countries through the study of satisfaction with tourists’ increasing demand for accommodation. The total number of tourist nights spent at accommodation establishments continues to increase. Nevertheless, the growth of this indicator is significantly different across both regions and accommodation activity types. Moreover, the decrease in the number of tourist nights spent due to the impact of crises and destructive factors also varies. Based on the results of a data analysis of the Eurostat online database, we found that the number of beds at the accommodation establishments is not a key factor that determines the number of tourist nights spent. This finding represents the importance for the development strategy of considering not only the capacity of accommodation establishments, but also the variety of accommodation activity types. The data analysis of some countries’ cases points out that even a less robust accommodation industry has opportunities to develop in a difficult and uncertain period. This study result has practical applications in an effective development strategy particularly in a time of crisis.
