Authors: Tabli Dalila , Touka Nassim , Baddari Kamel , Selmi Nourddine 
Published: October 2022

Abstract
The physical properties of pure CuO and Pb doped CuO thin films, deposited on glass substrates by a sol-gel method, were investigated. Structural analysis revealed the polycrystalline nature of the pure CuO and Pb:CuO composite films with a monoclinic structure, the crystallite size decreased and ranged from 36.78 nm to around 21.5 nm. The SEM images of the CuO thin films showed that the Pb doping concentration affects the surface morphology of the Pb:CuO composites. The absorbance of the Pb:CuO composites is higher than that of the undoped CuO thin films. The optical band gap energies of undoped CuO and Pb doped CuO thin films were estimated to 1.9 (pure), 2.17(5%) and 2.74 (7%)eV, and found that the band gap energy (Eg) increases with the Pb concentration. This blue shift is due to the quantum confinement induced by the reduction in the size of the crystallites.

Published: October 2022

Abstract
Surfaces of cam shafts made of AISI 8620 steels were hardened by boriding processes in both solid and liquid mediums. Various chemical agents were used to achieve boride layers on the surfaces of the cam shafts in these processes. It was aimed to examine effects of the chemical agents on microhardness and thickness of the boride layers obtained. It was concluded that a bath composition of 5% B4C-90% SiC-5% KBF4 was appropriate for the hardest and thickest boride layer achieved in the solid medium, and a composition of 70% Na2B4O7-30% B4C in the liquid medium.
g-C3N4/ Bio–Synthesized Silver Nanoparticle for Fluorometric Bio-Sensing of Acetylcholinesterase and Malathion
Authors: Ali Abdu Hussen 
Published: October 2022

Abstract
Malathion is widely used in agriculture due to their high efficiency as insecticides. They are very toxic hazardous chemicals to both human health and environment even at low concentration. The detection of pesticides (malathion) at the low levels developed by the environmental protection agency (EPA) still remains a challenge. A highly efficient fluorescent biosensor based on g-C3N4/AgNPs for AChE and malathion detection is successfully developed by impregnation method. The structural and morphological properties of the nanocomposites were characterized by using powder X-ray diffraction (XRD), fourier- transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The analysis confirmed that there is a strong interfacial interaction between g-C3N4 and AgNPs. The fluorescent responses show an increase in intensity upon the additions of AChE which indicates that AChE as enzyme was hydrolyzing the substrate ACh, with the increase in oxidative electron as the preferred route of reaction. The developed OFF-ON sensor immobilizes by Actylcholestrase (AChE) and use as new probe for malathion detection. In the absence of malathion, AChE−g-C3N4/AgNCs exhibit high fluorescence intensity. However, the strong interaction of the basic sites to malathion, causes fluorescence quenching via static quenching and Ag form aggregation on the surface of g-C3N4. The experimental parameter such as pH of buffer (pH=6), concentration of acetylcholine (1 mM) and malathion (500 μM) were optimized. The sensor was also more sensitive with Stern-Volmer quenching constants (KSV) of 3.48x10 3 M −1. The practical use of this sensor for malathion determination in Khat was also demonstrated. The obtained amount of malathion in Khat is 168.8 μM.
Analytical Description of Concentration of Radiation Displacement Defects in Oxide Crystals as Function of Electrons or Neutrons Energy
Authors: Potera Piotr 
Published: October 2022

Abstract
The main purpose of this work is the description of dependence of the concentration of radiation displacements defects (RDD) induced by electrons and neutrons in garnets, perovskites, silicates, germanates, and tungsted bronzes type crystals (Y3Al5O12, Gd3Ga5O12, YAlO3, LiNbO3, Bi4Si3O12, Bi4Ge3O12, Ca0.28Ba0.72Nb2O6) on the energy of particles by analytical function. The dependences were determined on the basis of calculations made using the Monte-Carlo method realized in the Atom Collision Cascade Simulation program. The results of calculations show that the concentrations of RDD reduced to one impinging particle increased initially with the particles energy and they saturates for the electron and neutron energy above 3–36 MeV, depending on crystal, sublattice and kind of irradiation particle. A wide range of energies for which the concentration of RDD is independent of the energy of particles (neutrons, electrons) makes them potential materials for the dosimetry of high-energy particles. The comparison of the concentrations of RDD calculated for different sublattices as well as for the cases of electrons and neutrons is made. In the case of irradiation with electrons, the relative concentration of RDD of the oxygen sublattice strongly depends on the energy of electrons and the crystal and varies in the range of 10–90%. In the case of neutrons, the relative concentration of RDD of the oxygen sublattice does not depend on the neutron energy and is in the range of 66–84% depending on the crystal.

Abstract
In order to explore the analysis of educational management strategies in Colleges and universities, a method based on entropy and dissipative structure theory is proposed. Firstly, we determine the connection length B, which refers to the shortest path between two elements in the structure diagram. The length of direct connection is 1, and the length of each transfer is added by 1. Secondly, calculate the total number of microscopic states of the system, A
1, A
1 = ∑∑ Lab, Third, calculate the probability value of the realization of the micro state of each connection:

P\left( {a,b} \right) = {{{L_{ab}}} \over {{A_a}}}

. Finally, the entropy of organizational structure between any two elements of the system at the same level vertically and horizontally is calculated: H

(ab)lnPa
(ab). The experimental results show that student satisfaction is considered to be an important dimension of management team performance evaluation. Through the survey of student satisfaction, it is found that the student satisfaction rate of two teams is 100%, the student satisfaction rate of two teams is 99%, and the satisfaction rate of one team is 98.5%, which shows that the management team has good performance. It is proved that the theory of entropy and dissipative structure can effectively improve the educational management strategy of colleges and universities.

Published: October 2022

Abstract
We study the motion states of charged particles in a homogeneous electromagnetic field based on the Maxwell equations. The authors propose the charged particle properties analysis based on the Maxwell equation and electromagnetic field, first explain the Maxwell equation and electromagnetic field properties analysis, and then analyze the charged particles in the composite field (electric and magnetic field coexistence). List the important knowledge points about the motion of charged particles in an electric field, and determine the center of the circle where the charged particles move in a circular motion, simulate the motion of charged particles in a uniform orthogonal electromagnetic field, if at, the trajectory of the charged particle is a short-amplitude cycloid, if, the trajectory of the charged particle is a long cycloid, if. The realization of simulation is mainly based on theory to obtain phenomena, although it has extensive practical significance for confirmatory experiments, when inspiring and guiding students to carry out inquiry learning, physics teachers should still organically combine simulation experiments with traditional experimental teaching, teacher explanations, and student experiments in teaching design and teaching implementation, in order to cultivate students' independent inquiry ability and experimental innovation ability.

Authors: Xu Peng , Zhang Xiaohui , Soltan Mohamed Abdeldayem 
Published: October 2022

Abstract
In order to study the image detection of multimedia sensor based on constrained under determined equation, this paper proposes the improvement of image sensor quality detection method based on image recognition algorithm. Firstly, the principle and steps of the under determined method are explained, and the complexity of the algorithm is analyzed. The image sensor is the most important part of the mobile camera, which determines the performance of the mobile camera, and its assembly quality largely determines the quality of the whole mobile camera. The case studied in this paper is model h mobile phone camera, and the first pass rate of good products is only 80%. In order to meet the 95% pass rate of good products required by customers, it is necessary to comprehensively improve the processes that have a great impact on product quality, so as to improve the first pass rate of products, achieve quality objectives and reduce manufacturing failure costs. In order to find out the threshold value of the height information measured by the improved method, to determine whether the product is good, and to find out the process that has a great impact on the surface flatness of the image sensor, the product measurement experiment is specially set. The improved war page test method was used to measure the products of each experimental group. Among them, No. 22, No. 39 and No. 40 products are poor due to changes in physical properties in subsequent production, and cannot flow to the next process for production. Therefore, the data of No. 22, No. 39 and No. 40 are missing in the test data. A total of 133 groups of experimental data were obtained in this experimental test. The results showed that the standard deviations of group 1, group 2, group 3 and group 4 were 0.172, 0.125 and 0.304 respectively. That is, after the same product is treated by false hardening, heating hardening and base installation processes, the false hardening and heating hardening processes have relatively little impact on the surface flatness of the image sensor. After the base opening and installation process, the surface flatness of the image sensor begins to change. The standard deviations of the measurement results of group 1 and groups 4, 5, 6 and 7 were 0.304, 0.381, 0.391 and 0.514 respectively. That is, after the base installation, calibration, bonding, soldering and testing of the product, the surface flatness of the image sensor and the initial surface flatness have changed greatly. Therefore, production technicians can focus on the process that starts to change, that is, the base installation process. The improved method has the advantages of automatic operation, low error, low error rate and so on.
Epidemiology-constrained Seating Plan Problem
Authors: Dąbkowski Jakub , Kacperski Przemysław , Kaleta Mariusz 
Published: October 2022

Abstract
The emergence of an infectious disease pandemic may result in the introduction of restrictions in the distance and number of employees, as was the case of COVID-19 in 2020/2021. In the face of fluctuating restrictions, the process of determining seating plans in office space requires repetitive execution of seat assignments, and manual planning becomes a time-consuming and error-prone task. In this paper, we introduce the Epidemiology-constrained Seating Plan problem (ESP), and we show that it, in general, belongs to the NP-complete class. However, due to some regularities in input data that could a affect computational complexity for practical cases, we conduct experiments for generated test cases. For that reason, we developed a computational environment, including the test case generator, and we published generated benchmarking test cases. Our results show that the problem can be solved to optimality by CPLEX solver only for specific settings, even in regular cases. Therefore, there is a need for new algorithms that could optimize seating plans in more general cases.

Authors: Casman Casman , Nurhaeni Nani , Waluyanti Fajar Tri 
Published: October 2022

Abstract

Objective
The rehospitalization rate of children <5 years old with pneumonia is still high. The risk of hospitalization becomes higher in mothers with low knowledge of their child's disease. The purpose of this study was to determine the effect of post–health-education maternal knowledge in cases of rehospitalization and to determine the differences in rehospitalization rate based on the type of health education media.

Methods
This study is a quasi-experiment. Health education was given to both groups: one group received education through audiovisual media and the other group through leaflet media. The level of post–health-education knowledge was measured on the third day, then followed up until the 30th day after the patient was discharged from the hospital.

Results
Post–health-education knowledge significantly reduced the cases of rehospitalization in both groups. However, the rehospitalization rate in the audiovisual group was lower than in the leaflet group (P = 0.047, odds ratio = 5.870).

Conclusions
Post–health-education knowledge is effective in reducing the risk of rehospitalization, and health education using audiovisual media is more effective, compared to health education using leaflets, in reducing the cases of rehospitalization in children <5 years of age with pneumonia.
Development and psychometric evaluation of the Ethical Behavior for Thai Nurses Scale
Authors: Orathai Pisamai , Prapaipanich Wonnapha , Arpanantikul Manee , Senadisai Supanee 
Published: October 2022

Abstract

Background
Ethical problems in the nursing profession are mostly found in the undesirable ethical behavior (EBE) of nurses. If there is no concern about these problems, it may negatively affect the quality of nursing care, patients’ safety, and trust in the nursing profession. In assessing nurses’ EBE, it is important to develop an instrument that reflects the actual EBE of nurses.

Objectives
To develop and evaluate the psychometric properties of the Ethical Behavior for Thai Nurses Scale (EBTNS).

Methods
The construct definition, 5 sub-constructs, 43 items, and the hypothesized model were synthesized and generated from a comprehensive literature review and existing research instruments by using document analysis. The EBTNS was verified for content validity by 4 experts. Of the 43 items, 37 items were retained for psychometric testing. The construct validity was tested by using second-order confirmatory factor analysis (CFA). The EBTNS was tested on 1500 professional nurses working at tertiary, secondary, and primary hospitals in 6 regions (the central, northern, northeast, eastern, western, and southern) of Thailand. Proportional quota sampling was applied to recruit participants.

Results
The hypothesized model fitted the empirical data. All 37 first-order indicators and 5 second-order sub-constructs showed significantly standardized factor loadings and effect sizes. The standardized factor loadings of 37 first-order indicators ranged from 0.58 to 0.89, and the construct reliabilities were moderate to substantial (R
2 = 0.34–0.79). The 5 second-order sub-constructs displayed the standardized effect sizes, ranging from 0.81 to 0.96, and accounted for 65%–96% of the total explained variance. In addition, the construct validity was supported by convergent validity and discriminant validity. It also satisfied Cronbach's alpha coefficients of 5 sub-constructs from 0.87 to 0.94, and a full scale was 0.97.

Conclusions
The psychometric properties of the EBTNS are acceptable. This instrument has the potential to be used for evaluating and monitoring to prevent ethical problems of Thai nurses.
