Authors:   Academy of Public Administration under the President of the Republic of Azerbaijan, Azizbayov E.I. ,   Baku State University, Mehraliyev Yashar
Published: November 2023

The paper studies the classical solvability of an inverse boundary value problem for a second order parabolic equation with nonlocal boundary conditions. For this purpose, first, the considered problem is reduced to an auxiliary equivalent problem in a certain sense. Then, using the Fourier method the auxiliary problem is presented as a system of integral equations. Further, by means of the contraction mappings principle the unique existence of the solution of the obtained system of integral equations is shown. At the end of investigation the existence and uniqueness theorem for the classical solution of the original inverse boundary value problem is proved based on the equivalence of these problems

Authors: Erhabor Norris Igbinosa
Published: November 2023

The aim of this study was to determine the impact of environmental education on the knowledge and attitude of students from the Health, Safety and Environmental Education (HSE) and Human Kinetics Departments of the Faculty of Education, University of Benin, Benin City. The quasi-experimental research design was adopted for the study. The simple random sampling technique was used, and a sample size of 200 respondents was selected, with 100 respondents each from both the HSE and HKS departments, which made up the experimental group and control group of the study respectively. Data obtained for the study through a validated instrument were subjected to analytical tools such as frequency and percentage tables, and the T-TEST for testing the null hypothesis (Ho) at a 0.05 level of significance, on the relationship between environmental education and knowledge and practice of waste segregation in solid waste management between the two study groups.

Findings from the study show that there is a significant difference in knowledge and attitude towards waste segregation among students exposed to environmental education, compared to those not treated or exposed to the same, hence emphasising the impact and relevance of environmental education to waste segregation practices. Segregation was found to be an essential part of waste management, and involves the collection of wastes in different types/colours of bins or bags, sorting according to the different material components and separating wastes into useful and useless items at the point of collection. The benefits include a clean and healthy environment, conversion of disposed materials to reusable items, and management of solid waste.

Published: November 2023

The directional character of ultrasonic wave attenuation in polycrystalline material is presented for several titanium alloy samples Ti64 (Ti-6Al-4V) with different mean macrozone sizes. An experimental immersion setup is used to measure the attenuation of longitudinal and shear waves in a representative set of directions in space. This experimental attenuation can be divided into three different components: one due to the grain scattering and absorption in the sample, another due to the interaction between the wave and the sample boundaries, and yet another accounting for the remainder. For calculating the boundary component, a theoretical model capable of predicting the reflection/transmission coefficients is employed. A low attenuation sample of fused silica is used to calibrate the remainder of the amplitude loss due to the system characteristics. The material attenuation of the sample is expected to behave in such a way that the sensitivity of the shear wave to macrozone sizes is shown. This experimental data will also be relevant when attempting the refinement of a theoretical model for shear wave attenuation due to grain scattering.
Deep learning for quantification of porosity in metallic components based on synthetic ultrasonic signals
Authors:   Pennsylvania State University, Skiadopoulos Michail , Shokouhi Parisa ,   Pennsylvania State University
Published: November 2023

A machine learning-based method is proposed to quantify porosity in metallic components based on their ultrasonic response. A feed-forward multi-tasking neural network (NN) model is created; the input is the unprocessed ultrasonic signals obtained from 2D finite elements (FE) simulations of ultrasonic pulse-echo testing on porous aluminium samples and the output are the number of pores and the average pore size. Our model performs well (R2 = 0.81) in porosity predictions although it does not generalize well when predicting the average pore radius, possibly due to a relatively small training set. The deep learning model results are shown to be superior to those from analytical models relating porosity, attenuation and wave speed. These findings highlight the utility of machine learning for quantitative ultrasonic characterization of porosity.
Electrical Impedance Tomography for Embedded Sensing and Nondestructive Evaluation: A Perspective for Advancement
Authors:   Purdue University, Tallman Tyler N.
Published: November 2023

Electrical impedance tomography (EIT) is the process of mapping the spatially varying conductivity distribution of a domain. In the last couple of decades, EIT has been explored for the nondestructive evaluation (NDE) and embedded sensing of structures and materials. The supposition in these applications is that many materials have electrical conductivity that responds to deleterious effects; thus, EIT can conceivably be used to detect and localize these effects. This field, however, has become saturated with results that do little to transition EIT out of the proof- of-concept phase and into meaningful practice. As an antidote to this stagnation, a perspective is herein provided on critical challenges that need to be addressed to make EIT truly viable for NDE and embedded sensing.

Authors:   University of Utah, Zhang Keping , Wu Yuning , Zhu Xuan ,   University of Utah
Published: November 2023

Local resonances, formed by zero-group velocity (ZGV) and cutoff frequency points, have been extensively studied using impulse induced by pulsed lasers and impacts. In this work, we demonstrated the effectiveness of the electromechanical impedance (EMI) technique in extracting ZGV and cutoff frequency resonance in a rectangular aluminum bar. We identified the mechanisms of multiple resonances in the EMI spectra through the analysis of dispersion relations. Moreover, we extracted the spatial wave profile at a cutoff frequency and a ZGV frequency to confirm the localized energy behavior in the vicinity of the excitation source.

Long-term ultrasonic monitoring of concrete damage under ambient condition
Authors:   University of Nebraska-Lincoln, Zhu Jinying , Tang Yalei , Tu Jiuzhou ,   University of Nebraska-Lincoln
Published: November 2023

This paper presents a study of long-term ultrasonic monitoring of concrete with microcracking damage under ambient condition. Although relative wave velocity change (dv/v) has been used to evaluate microcracking damage initiation and development in concrete, few studies have examined the long-term velocity change in concrete structures under ambient temperature conditions. In this study, we monitored wave velocity changes in different concrete specimens over an extended period (more than one year). We found that the relationship between dv/v and temperature can indicate the damage level in concrete, which might be used to evaluate concrete structures using the ambient temperature changes.
Material Texture Characterisation in Metallic Curved Components using Diffused Ultrasound
Authors:   Imperial College London, Png Melody , Lowe Michael J.S. , Lan Bo ,   Imperial College London
Published: November 2023

During fabrication of any metal component, processes that involves plastic deformations could result in a preferred crystallographic orientation (texture) in the material, which defines the component’s material properties. To overcome the limitations posed by several state-of-the-art texture characterisation methods, Imperial College’s Non-Destructive Evaluation (NDE) group has developed a bulk texture measurement method using ultrasonic velocities from immersion ultrasound. However, this immersion technique could only inspect raw material blocks with parallel flat surfaces. This restrains inspection on components that tends to have a more complex geometry near the end of the manufacturing process, and whose texture is more critical for real applications. This paper proposes the use of diffused ultrasonic fields for velocity measurements to reconstruct texture in metallic components with curved surfaces. With the aim of obtaining velocity values at different angles with high precision, velocity measurements using diffused fields, firstly with phased arrays, will be shown. The results are calibrated against conventional coherent velocity measurements, and it is shown that the former has good agreement with the latter within an angular range of 70°. Preliminary trials were also conducted with lasers as receivers. To aid the understanding of the wave diffusion process, a simulation model has also been developed and used to illustrate wave interactions with microstructures within the sample, and to optimize the velocity measurements.

Authors:   Institute for Diagnostic Imaging Research, Ouellete Andrew , Chertov Andriy , Maev Roman Gr. ,   Institute for Diagnostic Imaging Research
Published: November 2023

In recent years, the automotive industry has been adopting real-time inspection of resistance spot welds using a single-element ultrasonic probe. With the introduction of the advanced materials that are more prone to defects such as pores, expulsions and non-symmetric heat distribution, monitoring both the lateral and vertical growth processes of spot weld nugget formation have become very desirable in the sheet-assembly industry. To address this ever-growing need, we have advanced the research and development of the existing technology to a new stage: monitoring the spot weld in more than one dimension, making use of an array of point-source-like micro elements.
NDE 4.0. Realizing zero-defect mass production of bonded joints by integrating AI into the advanced real-time ultrasonic quality monitoring process
Authors:   Institute for Diagnostic Imaging Research, Maev Roman Gr.
Published: November 2023

The future of NDE in light of the increasing use of artificial intelligence – particularly deep learning – is at least uncertain if not controversial. In many ways, deep learning has brought ground-breaking advancement in NDE data interpretation and downstream decision-making – and promises to continue to do so. On the other hand, widespread use of deep learning artificial intelligence in NDE 4.0 advanced requirements is impeded due to some major challenges and concerns regarding its role, development, standardization, metrology, consistency, validation, generality, trustworthiness, coexistence with human experts, and ethical use – among others. In this talk, we will discuss some of these major challenges and concerns regarding the use of deep learning in NDE, along with case studies from our work and examples from the works of others. In particular, we will discuss the case of the implementation of resistance spot weld (RSW) process monitoring using a deep learning approach which analyzes ultrasonic M-scans via semantic segmentation in real time. Our AI can assess throughout the weld process various weld properties including for example the amount of nugget penetration into each sheet in the stack up. These assessments are fed back to an adaptive weld controller so it can always produce high-quality welds that match production-level requirements. Such an approach achieves this and is a great example of advancement in NDE 4.0 and its potential impact in the future of manufacturing.

Authors: Nargis Rifat Ara , Pulipati Daniel , Jack David A. ,   Baylor University
Published: November 2023

Carbon fiber laminates are becoming popular in the manufacturing industry for their many desirable properties; like good vibration damping, high strength to weight ratio, toughness, high dimensional stability, low coefficient of thermal expansion, etc. During the manufacturing process, undesirable foreign objects, such as peel-ply strips, gloving material, Kapton film, etc. can be introduced into the part which can lead to a localized weakness that is a function of the FOD material and geometry. These manufacturing defects can act as stress concentration points and sometimes cause catastrophic failure. In this study, a method using pulse-echo ultrasound testing is used for the detection and quantification of the dimensions of foreign object debris (FOD) within carbon fiber laminates. This study presents a method to create high-resolution c-scans, and from the full-waveform dataset extract the FOD depth and planar dimensions with an automatic edge detection technique. Results from three carbon fiber laminates are investigated with embedded foreign objects ranging from 1.5 mm to 12.7 mm in the effective diameter, with error in quantification from the ultrasound data of 0.2 mm to 0.36 mm. CT imaging is used to confirm the FOD was not altered during manufacturing, and the as manufactured FOD dimensions were equal to the as designed FOD dimensions to within the resolution of the CT configuration utilized in the study. Of importance for the ultrasound inspection, in every case the FOD is detected, the layer depth is properly identified, and the spatial dimensions of the FOD are quantified to within 0.36 mm. This work is the first stage of a larger project leading to an FAA 8110-9 for FOD identification within a laminated composite.

Published: November 2023

In most previous works, the ultrasonic nonlinearity is assumed to be uniformly distributed throughout the material. However, the effects of local nonlinearity are attracting interests recently. In this work, the quadratic nonlinearity parameter field is built with a sufficient number of Gaussian kernels, then the single Gaussian beam model of second harmonic wave is developed considering random local nonlinearities. The results show that the degree of nonlinear ultrasonic beam fluctuation depended strongly on the complex microstructure of the inhomogeneous material.

Authors: Wilcox Logan M. , Donnell Kristen M ,   Missouri University of Science and Technology
Published: November 2023

Active microwave thermography (AMT) is a coupled electromagnetic and thermographic technique that employs an electromagnetic excitation with subsequent infrared measurement of a structure under test. This work proposes AMT as a potential solution for void-type defect detection in foam structures backed by an electromagnetically lossy substrate. Such inspections are generally challenging for thermographic techniques due to the thermally insulating properties of foam itself. Using AMT, void defects were detected at multiple depths and varying cross-sections through a multilayer foam structure with a lossy substrate.

Authors:   Korea Association of International Development and Cooperation, Kim Eunju , Choi Changyong
Published: November 2023

Purpose: The purpose of this study is to examine the perception of the Korean and American people on international development cooperation, which has different policy goals, means, and policy targets with domestic policies.
Originality: In international relations, a new approach is needed according to the diversification of actors such as the state-market-civil society. It is necessary to pay attention to the perception or values of ordinary citizens, which have been relatively neglected in the existing international relations theories.
Methodology: This study conducted a survey of 1,500 people in each country to find out the perception of Korean and American people on ODA. It asked which of the three aid goals, realism, idealism, and global communitarianism, was the most desirable goal. First, the difference in perception between the people of the two countries was analyzed through a chi-square test. Second, a multinomial logistic regression analysis was conducted to find out the factors influencing public perception of ODA goals.
Result: First, it was found that conservatives are more likely to pursue realistic goals, and progressives are more likely to pursue global communitarianism. Second, people who are more interested in domestic policy are more likely to see that their country's economic and social interests should be pursued for ODA goals. Third, when the household's economic level did not deteriorate due to COVID-19, the probability of considering the socio-economic development of the recipient country as a more important goal increased. Fourth, it can be interpreted that individuallevel variables have a greater impact in emerging donor countries, while policies and politics variables have a more impact on traditional donor countries.
Conclusion and Implication: It is necessary to engage people in international development cooperation as important actors to improve the quality of international development cooperation of South Korea, as a global pivotal country.
A Study on the Impact of ESG Performance Gap between Developed and Developing Countries on the International Inequality
Authors:   Korea Association of International Development and Cooperation, Kim Hyojung
Published: November 2023

Purpose: This study aims to critically examine ESG by raising questions about whether the ESG principles are achieving their essential purpose. And it tries to analyze the status of the ESG performance gap among national actors in order to find out the problems of current ESG trend.
Originality: Despite its significance in international relations, there remains a lack of theoretical analysis on the ESG centered on state actors. Also, excessive attention was paid to the evaluation results of the ESG rather than the actor’s activities considered ESG factors. This research analyzes the types of interactions among state actors, focusing on the ESG field and considers what they mean.
Methodology: This article uses content analysis, a qualitative case study methodology.
Result: The current ESG evaluation was able to confirm a tendency to depend on the legal and institutional infrastructure within actors, and the differentiation of these legal and institutional infrastructures caused the ESG performance gap between actors. In other words, the gap in the ESG performance of actors has an inherent income bias. This gap in ESG performance serves as a major variable in the process of making investment decisions based on ESG evaluation, thereby excluding developing and underdeveloped countries with low scores in ESG evaluation from ESG investment destinations. Accordingly, it was revealed that ESG is contributing to the deepening of international inequality.
Conclusion and Implication: This study drew the result that the ESG introduced for the purpose of improving the sustainability of actors can act as a factor that deepens inequality within the international community. Prior to emphasizing the internalization of ESG principles by actors, consideration must be given to a standardized ESG evaluation framework within the international community, and consideration is needed to ensure that all actors are provided with a fair opportunity.

Published: November 2023

The development of the technology of vitaminized dairy products remains a relevant topic for research, because dairy products are included in the daily diet of both children and adults, so the use of such products can reduce the number of cases of hypovitaminosis, both seasonal and general. The purpose of the study is to investigate the effect of introduced ready-made vitaminized complexes on the fermentation process of milk mixtures during the production of yogurt. The article presents the results of studies conducted to determine the effect of vitamins A, D, E, C on the fermentation process of milk mixtures during the production of yogurt, which were added to the milk mixture in order to increase the biological value of the finished product. Fermentation is an important stage in the production of yogurt. To study the influence of added preparations of vitamins A, D, E, C on the fermentation process during the production of yogurt, 2 samples were chosen: “control” – a milk mixture for yogurt pasteurized at 90...92 °C without aging with the addition 5 % sugar. The “experimental” sample is a milk mixture for yogurt with the addition of 5 % sugar, pasteurized at 90...92 °C without aging, with the addition of vitamin preparations. Fermentation processes are influenced by the composition and dose of primary inoculation of sourdough cultures, physicochemical parameters of raw milk, additives included in the normalized mixture, as well as technological process parameters. Vitamins added to the milk mixture during the production of yogurt can affect the fermentation process of the milk mixture and the quality indicators of the finished product during storage. Thus, the task arose to investigate the effect of added preparations of vitamins A, D, E, C on the fermentation process, and to substantiate the fermentation regimes for the production of vitaminized yogurt. As a result of the conducted research, it was determined that vitamin preparations added to the milk mixture before heat treatment did not significantly affect the intensity of acid formation and gel formation. There is also no influence on the development of lactic acid microorganisms that were part of the sourdough, which is confirmed by the results of microbiological studies of the finished product. So, the fermentation parameters of milk mixtures for the production of fortified yogurt are as follows: temperature – (40 ± 2) °C, duration of fermentation – 5.5...6 hours. It has been established that the introduction of a vitaminized complex (A, D, E, C) into the yogurt recipe does not require significant changes in the technological process and equipment line. The content of viable lactic acid bacteria in the developed product is 4.0 ± 0.5 107 CFU/g, and there are no Coliforms, which meets regulatory requirements.

The urgency of the protection of domestic products in supporting economic value and increasing market competitiveness plays a large role through the registration of intellectual property rights (E-IPR). The existence of intellectual property in providing legal security for domestic products was essential for its certainty and safety. This should be done asa precaution in anticipation of unhealthy business rivalries and a minimizing of counterfeit products in the market. The methods used in supporting this study through normative research using a constitutional and case approach. Additionally, it sustained the legal source from primary and secondary data and was analyzed using descriptive analysis methods. The purpose of research is to determine the extent to which intellectual property rights protection has played in supporting the success of domestic products in the market. In view of the high presence of domestic products, the intellectual property rights registration is required by governments and stakeholders through the creation of domestic products to ensure early legal awareness of the resulting creativity needed to protect them by intellectual property. The implementation of intellectual property e-rights (E-IPR) is part of the economic laws of development because it includes efforts to enhance and develop domestic products and thus protect the state, improve the competiting power of the product, and create social welfare.
Effects of Local Soil Profiles on Seismic Site Response Analysis
Authors: Chala Ayele , Ray Richard
Published: November 2023

Local soil conditions play a significant role in the intensity variations of seismic waves during earthquakes. These variations can be either amplified or de-amplified depending on the specific soil conditions. This study aimed to assess the impact of different soil profiles on seismic site responses. The study considered four types of site profiles: sand (Sa), clay (Cl), sand overlying clay (SaCl), and clay overlying sand (ClSa) profiles. To simulate the ground motion, we selected seven sets of strong earthquake records from the European Strong-Motion Database. These records were selected according to Eurocode-8 with a peak ground acceleration (PGA) of 0.24 g, site class A using REXEL computer program. The records were then applied to the bedrock at a depth of 30 meters. Subsequently, a series of 1-D equivalent linear (EQL) response analyses were performed using the STRATA. Amplification factors (AFs) and surface acceleration time histories provided quantitative evaluations for our analysis results. The results demonstrated that site profiles with clay overlying bedrock (SaCl and Cl profiles) exhibited higher seismic amplification and peak ground acceleration in comparison to site profiles with sand overlying bedrock (Sa and ClSa profiles). The maximum median AF is calculated from the SaCl site profile, while the minimum median AF was calculated from the ClSa profile. The relative difference between the maximum and the minimum median AFs was about 33.7%. Based on these results, we can conclude that soft local soils have a pronounced effect on the amplification of seismic waves compared to stiff local soils.

The Bengkulu City area often experiences extreme weather with the potential for flooding and affects various types of human activities. This study aims to determine the effect of extreme weather predictor variables in Bengkulu City by using Statistical Product and Service Solutions (SPSS). Extreme weather indicators are  reviewed  based  on  rainfall  with  estimating  variables  in  the  form  of  air pressure, humidity, air temperature, and wind speed, for 5 years (2017-2021) obtained from the BMKG Station on Baai Island, Bengkulu City. Data processing using SPSS method. Data analysis was carried out statistically and descriptively. Based on the results of the study, the correlation between the estimator variables on extreme rainfall is quite good with r = 0.661, and the error value (RMSE) is 27,124. Furthermore, the homogeneity test between extreme rainfall indicators and extreme weather estimators   includes   air   pressure, air   temperature, wind   speed,  and   air   humidity,   showing homogeneity in 2019. This indicates the predictor variable has the same direction to extreme rainfall, where the error value is obtained tends to be relatively small. The estimator variables, namely air pressure and humidity, have a significant relationship with extreme rainfall. Predictions using data (2017-2021) show that in 2022, extreme rainfall events will occur for a relatively long time, namely in January, March, May, June, July, August, October, and December. The most extreme rainfall intensity occurs in January

Small and Medium-sized Enterprises (SMEs) play an important role in Morocco’s economy in terms of job creation and GDP. It is therefore essential to better understand how SMEs are created and developed in order to render the economy more resilient. This research attempted to identify Moroccan entrepreneurs’ motives for self-employment, which determinants of success they saw as most important, and which obstacles they identified as major business threats. In that perspective, a questionnaire derived from the literature was administered to a sample of 245 Moroccan entrepreneurs. Results revealed that Moroccan entrepreneurs were primarily motivated by economic, or extrinsic goals, by opposition to intrinsic goals such as a desire for autonomy and independence. Moroccan entrepreneurs were also more likely to favor success variables related to personal characteristics such as business training, field experience and marketing skills, while the lack of reliable personnel, strong competition, and a weak economy were perceived as major barriers to entrepreneurial success.
Tensorial and Hadamard Product Inequalities for Synchronous Functions
Authors: DRAGOMIR Sever
Published: November 2023

Let $H$ be a Hilbert space. In this paper we show among others that, if $f,$ $g$ are synchronous and continuous on $I$ and $A,$ $B$ are selfadjoint with spectra ${Sp}\left( A\right) ,$ ${Sp}\left( B\right) \subset I,$ then%
\begin{equation*}
\left( f\left( A\right) g\left( A\right) \right) \otimes 1+1\otimes \left(
f\left( B\right) g\left( B\right) \right) \geq f\left( A\right) \otimes
g\left( B\right) +g\left( A\right) \otimes f\left( B\right)
\end{equation*}%
and the inequality for Hadamard product%
\begin{equation*}
\left( f\left( A\right) g\left( A\right) +f\left( B\right) g\left( B\right)
\right) \circ 1\geq f\left( A\right) \circ g\left( B\right) +f\left(
B\right) \circ g\left( A\right) .
\end{equation*}%
Let either $p,q\in \left( 0,\infty \right) $ or $p,q\in \left( -\infty
,0\right) $. If $A,$ $B>0,$ then
\begin{equation*}
A^{p+q}\otimes 1+1\otimes B^{p+q}\geq A^{p}\otimes B^{q}+A^{q}\otimes B^{p},
\end{equation*}%
and%
\begin{equation*}
\left( A^{p+q}+B^{p+q}\right) \circ 1\geq A^{p}\circ B^{q}+A^{q}\circ B^{p}.

The purpose of this study is to analyze the trends in ‘conversation analysis’ research published domestically. A total of 459 relevant papers published from 2002 to July 2023 were collected and analyzed through the Korean Citation Index. First, the size of the published papers and the distribution of the journals in which the papers were published, as well as the academic fields to which the journals belong, were analyzed. Then, the characteristics of the citing papers that used these papers as references were identified, in order to analyze the academic influence. The significance of this study lies in not only comprehensively understanding the overall trends in domestic ‘conversation analysis’ research but also analyzing citation patterns that have not been examined in previous studies to determine the academic influence of these research papers.

Cognitive Linguistic Implications of Gender Conflict Hate Speech
Authors:   The Korean Society of Culture and Convergence, Han Juhee
Published: November 2023

The purpose of this study is to identify the cognitive linguistic meaning of sexist hate speech. Hate speech is speech that is discriminatory, hateful, or incites discrimination, hostility, or violence against a person or group of people. Hateful expressions referring to women and men have increased rapidly since 2012, when problems related to communities such as Daily Best, Warmad, and Megalia emerged, and gender hateful expressions such as kimchi girl, miso girl, mamchung, hannamchung, and gazer have increased. This phenomenon is explained by the emotion cognition model and the issue interest cycle model, and hate speech occurs under the premise of both models. The results showed that the metaphor and metonymy mechanisms were applied. We found that metaphorical words were mainly compared to animals or objects, and metonymy and metaphor were combined or re-metaphorized. Metaphorical words were characterized by the substitution of the whole for the part, as opposed to metonymy, in which the part takes the place of the whole, or the whole takes the place of the part. The intention of the words was to demean both men and women by referring to their behavior in certain situations or by using certain body parts.
