Diverse Approaches toward Application of Dental Pulp Stem Cells from
Human Permanent and Deciduous Teeth in the Treatment of Diabetes
Authors: Kanafi Mohammad Mahboob , Bhonde Ramesh Ramchandra
Published: March 2023

Background:

Diabetes Mellitus is defined by hyperglycemia, a condition which is the
result of defects in insulin secretion, insulin action, or both. Evidence suggest that islet transplantation
is a promising treatment approach, but the shortage of sources of insulin-producing cells is a
major problem. Ethical concerns and the limited availability of most stem cells have led scientists
to concentrate on mesenchymal stem cells, which are found in stem cells niches of all organs of the
body including dental tissues on which dental pulp stem cells (DPSCs) and stem cells from exfoliated
deciduous teeth (SHED) are the easiest accessible sources.

Highlights:

Generally, SHED show characteristics similar to DPSCs; however, its proliferative
and clonogenic capacities are higher. It has been proved that these two types of dental mesenchymal
stem cells are able to produce islet-like cells capable of insulin secretion. In this review, we
discuss various conducted approaches on the application of DPSCs and SHED in the treatment of
diseases associated with diabetes such as; pancreatic differentiation cocktails, 2D and 3D culture
techniques, factors that affect pancreatic differentiation, in vivo studies (direct administration of
DPSCs and SHED, administration of their secretome and encapsulation of their-derived insulin
producing cells), clinical trials and future perspectives of these approaches.

Conclusion:

Dental stem cell-based therapy has been considered as a promising therapeutic procedure
for treatment of diabetes. Major advances in research on the derivation of insulin producing
cells from DPSCs and SHED have enhanced our chance of re-establishing glucose-responsive insulin
secretion in patients with diabetes.

Authors: Ahmadinejad Izadmehr , Mardasi Kimia Ghanbari , Ahmadinejad Yasmina , Kahrizi Mohammad Saeed , Soltanian Ali , Merdasi Pooriya Ghanbari , Ahmadinejad Mojtaba
Published: March 2023

Aim:

Thyroid nodules are one of the most common clinical findings, with a prevalence of 68% in adults. Thyroid cancer is the fifth most common cancer in women.

Introduction:

The purpose of this study is to evaluate the diagnostic efficacy of Thyroid Imaging Reporting and Data Systems proposed by the American College of Radiology (ACR-TIRADS) for the diagnosis of malignancy in surgically resected thyroid nodules

Methods:

In this retrospective study, patients who underwent thyroid nodules resected surgically from 2018-2020 were included. Before resection, an ultrasound was performed for TIRADS scores, and after resection histopathology, thyroid mass was obtained. The outcomes of the two systems were statistically compared.

Results:

The mean age of the 146 included patients was 47.6 ± 14.08 years, of which 109 (74.7%) were female. Based on TIRADS, 47 patients (32.2%) were in TI-RADS TR3, 36 patients (24.7%) were in TIRADS TR2, 34 (23.3%) in TIRADS 4, 24 (16.4%) in TIRADS TR5 and 5 patients (3.4%) were in TIRADS TR1. The overall sensitivity was 79.9% when ACR-TIRADS TR4 was set as a diagnostic cutoff value. Considering the total of TIRADS TR4 and TIRADS TR5 as predictors of thyroid malignancy, the sensitivity was 74.5% and the specificity was 76.8%. The positive and negative predictive value was 60.3% and 76.8%.

Conclusion:

ACR-TIRADS 4 and 5 can be considered good predictors of malignancy in thyroid nodules. More studies, including larger samples, are required to obtain a better conclusion.
Application of Transabdominal Ultrasonography in the Diagnosis of Absent
Contractility - A Case Report
Authors: Hu Mingyang , Liu Dong
Published: March 2023

Introduction:

Absent contractility is a kind of esophageal motility disorder. Patients are often diagnosed by endoscopic ultrasonography or high-resolution
manometry (HRM). In this paper, we report two cases of absent esophageal contractility first discovered by transabdominal ultrasonography.

Case Presentation:

The main symptom of both cases was acid reflux, and the main diagnosis was absent esophageal contractility. They were all discovered by
transabdominal ultrasonography. After the treatment of surgery or drugs, the symptoms relieved during follow-up, without any other discomforts.

Conclusion:

Transabdominal ultrasound as a primary screening method for absent contractility is proposed in this paper, which is non-invasive, real-time, and
fast. Ultrasound is expected to improve the diagnostic efficiency of peristalsis and patient experience in combination with the above invasive
examinations. The use of sonography in the diagnosis of absent contractility has seldom been studied. Further investigation is required to determine
whether this technique may better assess absent contractility.
Risk Factors for Prolonged Intensive Care Unit Stay in Patients with
Hypercapnic Respiratory Failure
Authors: Naurzvai Nurgul , Mammadova Ayshan , Gursel Gul
Published: March 2023

Introduction:

Hypercapnic respiratory failure (HRF) is one of the most frequent reasons for intensive care unit (ICU) admissions. In this study, we aimed to investigate the risk factors for prolonged ICU stay in HRF patients for longer than 7, 10, and 15 days.

Methods:

Impact of demographics, vitals at the admission, comorbid disease severity, respiratory parameters, admission diagnosis, noninvasive mechanical ventilation (NIV) application time and settings, arterial blood gas, and blood biochemistry results were analyzed in patients with HRF to investigate risk factors for longer ICU stay.

Results:

A total of 210 patients who were admitted to ICU with HRF (PaCO2 values of 45 mmHg and higher) were included in this retrospective cohort study. The mean age of the patients was 69±12 years, and the mean ICU duration was 9±7 days. Forty-five percent of the patients stayed in the ICU for more than one week and %10 of them stayed for more than 15 days. Risk factors for a prolonged stay in ICU for more than 7 days were high SOFA score, acute renal failure (ARF) at admission, low PaO2/FiO2 on the 2nd day of admission, and high TSH level. Low FEV1 and FEV1/FVC ratio, ARF at admission, and low PaO2/FiO2 ratio on the 2nd day of admission were found to be risk factors for prolonged stay in ICU for longer than 10 days. Significant risk factors prolonging the ICU duration for more than 15 days were high SOFA score, low FEV1, low FEV1/FVC ratio (P = 0.008), and hypothyroidism (P = 0.037). FEV1% predicted less than 25.5% and FEV1/FVC% less than 46.5 % were significantly associated with ICU stay longer than 10 days.

Conclusion:

Earlier diagnosis and treatment of patients with hypothyroidism and severe airflow obstruction could shorten the length of ICU stay of hypercapnic patients.

piRNA Functions
Authors: Liu Yajun , Li Aimin , Zhu Yingda , Pang Xinchao , Hei Xinhong , Xie Guo , Wu Fang-Xiang
Published: March 2023

Backgroud:

PIWI-interacting RNAs (piRNAs) are a kind of small non-coding RNAs
which interact with PIWI proteins and play a vital role in safeguarding genome. Single nucleotide polymorphisms
(SNPs) are widely distributed variations which are associated with diseases and have rich
information. Up to now, various studies have proved that SNPs on piRNA were related to diseases.

Objective:

In order to create a comprehensive source about piRNA-related SNPs, we developed a publicly
available online database piRSNP.

Methods:

We systematically identified SNPs on human and mouse piRNAs. piRSNP contains
42,967,522 SNPs on 10,773,081 human piRNAs and 29,262,185 SNPs on 16,957,706 mouse piRNAs.

Results:

7,446 SNPs on 519 cancer-related piRNAs and their flanks are investigated. Impacts of 2,512
variations of cancer-related piRNAs on piRNA-mRNA interactions are analyzed.

Conclusion:

All these useful data and piRNA expression profiles of 12 cancer types in both tumor and
pericarcinomatous tissues are compiled into piRSNP. piRSNP characterizes human and mouse piRNArelated
SNPs comprehensively and could be beneficial for researchers to investigate subsequent piRNA
functions. Database URL is http://www.ibiomedical.net/piRSNP/.
Curbing Rhes Actions: Mechanism-based Molecular Target for
Huntington’s Disease and Tauopathies
Authors: Subramaniam Srinivasa , Boregowda Siddaraju
Published: March 2023

A highly interconnected network of diverse brain regions is necessary for the precise execution
of human behaviors, including cognitive, psychiatric, and motor functions. Unfortunately, degeneration
of specific brain regions causes several neurodegenerative disorders, but the mechanisms that
elicit selective neuronal vulnerability remain unclear. This knowledge gap greatly hinders the development
of effective mechanism-based therapies, despite the desperate need for new treatments. Here,
we emphasize the importance of the Rhes (Ras homolog-enriched in the striatum) protein as an emerging
therapeutic target. Rhes, an atypical small GTPase with a SUMO (small ubiquitin-like modifier)
E3-ligase activity, modulates biological processes such as dopaminergic transmission, alters gene expression,
and acts as an inhibitor of motor stimuli in the brain striatum. Mutations in the Rhes gene
have also been identified in selected patients with autism and schizophrenia. Moreover, Rhes SUMOylates
pathogenic form of mutant huntingtin (mHTT) and tau, enhancing their solubility and cell toxicity
in Huntington's disease and tauopathy models. Notably, Rhes uses membrane projections resembling
tunneling nanotubes to transport mHTT between cells and Rhes deletion diminishes mHTT
spread in the brain. Thus, we predict that effective strategies aimed at diminishing brain Rhes levels
will prevent or minimize the abnormalities that occur in HD and tauopathies and potentially in other
brain disorders. We review the emerging technologies that enable specific targeting of Rhes in the
brain to develop effective disease-modifying therapeutics.

Published: March 2023

In typical Internet of Things (IoT) networks, data is sent from sensors to fog devices
and then onto a central cloud server. One single point of failure, a slowdown in the flow of data,
identification, security, connection, privacy concerns caused by a third party managing cloud
servers, and the difficulty of frequently updating the firmware on millions of smart devices from
both a maintenance and a security point of view are just some of the problems that can occur. The
evolution of ubiquitous computing and blockchain technology has inspired researchers worldwide
in recent years. Key features of blockchain technology, such as the fact that it can't be changed
and a decentralised and distributed approach to data security, have made it a popular choice for
developing diverse applications. With the practically significant applicability of blockchain concepts
(specifically consensus methods), modern-day applications in ubiquitous computing and
other related areas have significantly benefited. In addition, we have taken advantage of the widely
available blockchain platforms and looked into potential new study fields. As a result, this review
paper elaborates the novel alternative privacy preservation options while simultaneously focusing
on the universal domain as a starting point for blockchain technology applications. We also
discuss obstacles, research gaps, and solutions. This review can assist early researchers who
are beginning to investigate the applicability of blockchain technology in ubiquitous computing. It
is also possible to use it as a reference in order to speed up the process of finding the appropriate
markers for ongoing research subjects that are of interest.
Development of indoor seismic damage simulator for evaluation of human injury
Authors: Sakuma H.
Published: March 2023

Abstract. Many people suffered severe injuries from crashing into furniture or falling when attempting to evacuate during a large historical earthquake. To assess human injuries during an earthquake, it is essential to estimate both the behavior of furniture and a human response to shaking. This study proposes a method for evaluating injury during an earthquake that considers the behavior of humans and furniture by constructing seismic response analysis models in a physical simulator. First, shaking table tests with human subjects were conducted to observe the behavior of a human during strong motions. Next, a human body model considering walking and falling was developed based on a cart-type double inverted pendulum with a feedback control system. To set appropriate feedback gains of the control system, the displacement and velocity of the head of the human body model were compared with those of the human subject in the shaking table test. Entering the strong motion recorded during the 1995 Hyogo-ken Nanbu earthquake into the human body model, the manner in which people behave and fall when they are walking during shaking was investigated. A static loading test of a bookshelf was conducted to measure the static and dynamic friction coefficients to construct a seismic response analysis model of the furniture. Finally, the human body and furniture models were incorporated into the physical simulator. The floor responses calculated by seismic response analysis of an RC super high-rise building were input to the simulator to evaluate the risk of human injury in the building. The degree of injury was quantitatively evaluated using head injury criterion.
Experimental test of patch antenna sensor for simultaneous crack and temperature sensing
Authors: Li X.
Published: March 2023

Abstract. This paper presents a patch antenna sensor for simultaneous crack and temperature sensing, and its actual performance is tested. The patch antenna sensor consists of an off-center fed underlying patch and an overlapping sub-patch, which is tightly attached to the underlying patch and allowing the electric current to flow through the integrated patch. The off-center feeding of the patch antenna can activate the resonant modes in both transverse and longitudinal directions. The resonant frequency shift in transverse direction is utilized for temperature sensing, and the crack width can be sensed by the longitudinal resonant frequency shift. Furthermore, this unstressed structure of the patch antenna sensor can avoid the problems of incomplete strain transfer ratio and the insufficient bonding strength. In this paper, the theoretical relationships between the antenna resonant frequencies, the environment temperature, and the crack width were studied. Experimental tests were also conducted, the off-center fed patch antenna sensor was fabricated and several days of continuous monitoring were performed to test the sensing performance of the patch antenna sensor. The experimental results demonstrate the feasibility of the proposed patch antenna sensor for simultaneous crack and temperature sensing.

Measurement of the refractive index using a goniometric system
Authors: Yurin A. I.  , Vishnyakov G. N.  , Minaev V. L.
Published: March 2023

The article proposes a method for measuring the refractive index using a goniometric system that does not require measuring the prism angle, which simplifies the measurement process compared to the widely used methods of minimum deviation and autocollimation. This method can be used to measure the refractive index of samples in the form of triangular prisms in the visible, ultraviolet and infrared ranges. To implement the method, a goniometric system was used. To obtain the reflection of the refracted beam, a fixed mirror was used, and the refractive index of the prism material was calculated from the solution of a system of equations. The results of an experimental study of a triangular prism made of optical glass N-BK7 using the proposed method and their comparison with the data obtained on the State Primary Standard of the Refractive Index Unit GET 138-2021 are presented. Keywords: goniometer, refractive index, prism method.

Published: March 2023

The single electron capture process from adenine molecules by H+, 3He+, N+, O+, and Ne+ ions with an energy of 6.3 keV has been studied. It was found that when one electron is captured by He+ and Ne+ ions, the dissociative capture process is dominant, which is fundamentally different from the processes of capture by singly charged ions of atoms with a lower ionization potential and multiply charged ions, as well as from the process of electron impact ionization. This effect is qualitatively explained within the framework of a quasimolecular model. Keywords: dissociative capture, nucleic acid bases, fragmentation, Landau-Zener model.

The condition of marriage and family is currently considered one of the most momentous problems of the Church and the state. The main purpose of the research presented in the book, conducted mainly with the help of statistical and sociological methods, was to obtain an in-depth description and analysis of the situational conditions and religious and social motivations of those initiating the process of declaring a marriage null before a diocesan tribunal in the Catholic Church. This, in turn, led to a deeper knowledge of the state of marriages and families in Poland. This task was accomplished through a quantitative survey, which made it possible to create a quantitative characterization of marriages whose validity was being examined by a church tribunal, and through a qualitative research based on the in-depth interview technique, from which a typology of people forming such marriages was built. The preceding research made it possible to grasp the profound diversity of situations and social behavior that result in the breakdown of marriage and family ties, as well as to identify specific reasons for the breakdown of marriages. The presented results can influence further studies of the condition of marriage and family both from the perspective of social sciences and theology.

Authors: Braund Taylor A , O’Dea Bridianne , Bal Debopriyo , Maston Kate , Larsen Mark , Werner-Seidler Aliza , Tillman Gabriel , Christensen Helen
Published: March 2023

Background

Mental disorders are prevalent during adolescence. Among the digital phenotypes currently being developed to monitor mental health symptoms, typing behavior is one promising candidate. However, few studies have directly assessed associations between typing behavior and mental health symptom severity, and whether these relationships differs between genders.

Objective

In a cross-sectional analysis of a large cohort, we tested whether various features of typing behavior derived from keystroke metadata were associated with mental health symptoms and whether these relationships differed between genders.

Methods

A total of 934 adolescents from the Future Proofing study undertook 2 typing tasks on their smartphones through the Future Proofing app. Common keystroke timing and frequency features were extracted across tasks. Mental health symptoms were assessed using the Patient Health Questionnaire-Adolescent version, the Children’s Anxiety Scale-Short Form, the Distress Questionnaire 5, and the Insomnia Severity Index. Bivariate correlations were used to test whether keystroke features were associated with mental health symptoms. The false discovery rates of P values were adjusted to q values. Machine learning models were trained and tested using independent samples (ie, 80% train 20% test) to identify whether keystroke features could be combined to predict mental health symptoms.

Results

Keystroke timing features showed a weak negative association with mental health symptoms across participants. When split by gender, females showed weak negative relationships between keystroke timing features and mental health symptoms, and weak positive relationships between keystroke frequency features and mental health symptoms. The opposite relationships were found for males (except for dwell). Machine learning models using keystroke features alone did not predict mental health symptoms.

Conclusions

Increased mental health symptoms are weakly associated with faster typing, with important gender differences. Keystroke metadata should be collected longitudinally and combined with other digital phenotypes to enhance their clinical relevance.

Objectives This study examines how the Protean career is revealed in the career development process of teachers in a socio-economic environment where change and diversity are pursued by exploring the turnover experience of secondary school teachers. Methods To this end, a Consensual Qualitative Research (CQR) method was applied to 8 former and incumbent secondary school teachers who had experience of job change to ensure objectivity. Results As a result of the study, a total of 252 core concepts were extracted, and 3 areas, 8 sub-areas, and 14 sub-categories were derived. Looking at 3 areas and 8 sub-areas, it was possible to confirm the perception of jobs such as ‘living as myself’, ‘living together’, and ‘economically self-reliant’. In the changeover process, it was analyzed as ‘starting change’ and ‘flexible coping with change’. Finally, the evaluation of job change was found to be ‘satisfied with life’, ‘integrating life’, and ‘continuing life’. Conclusions Looking at the experiences of various turnovers from the perspective of the whole life, it was confirmed that the challenge and flexibility to take the lead in change are opportunities for growth that newly create one's career and increase job satisfaction. This study is significant in that it explores the phenomenon of job turnover surrounding the profession of a teacher in modern society characterized by lifelong career development and borderless careers from a protean career perspective.

Objectives This study explored the experiences and perceptions of learners who use YouTube outside the classroom for self-directed English learning for Korean EFL university students. Methods We conducted a total of 155 Korean college students with an online survey from the first semester of 2021 to the first semester of 2022, and the questionnaire consisted of open-ended and closed-ended questions based on grounded theory. Results The findings indicated that 92.2% of Korean college students were willing to use YouTube videos for learning English. Participants wanted to improve their listening and speaking skills rather than their reading and writing skills through YouTube, and 64.5% spent less than 10 minutes a day learning English. The reasons why participants are satisfied with English learning through YouTube were found to be in three categories: “space for personal learning,” “social media efficiency,” and “indirect experiences.” On the other hand, they had difficulty in continuing to learn and showed a tendency not to regard it as a systematic learning material. Conclusions YouTube can be beneficial for learners’ self-directed English learning in that it includes various and practical materials anytime, anywhere, and free. To maximize this, learners should recognize that natural exposure to a second language environment through YouTube has a significant effect on improving English skills. In addition, learners must set clear goals and initiatives for a certain period to continue self-directed English learning.

Objectives This study explored Korean as a Second Language (KSL) students’ perceptions of the linguistic resources and activities in and outside the classroom. Methods Drawing on a sociocultural view of language learning and an ecological perspective, this paper presents the stories of five second language (L2) international students, who were enrolled in an undergraduate or graduate program. Using a qualitative case study method, this researcher analyzed data collected from interviews, a written questionnaire, students’ self-report, and other documents. The experiences of the focal students were compared and contrasted with each other and verified through additional perspectives, including the instructor and the leader of a campus extra-curricular club. Results The focal L2 students reported varying levels of marginalization in class due to language barriers. The research findings show that the participation of L2 international students in and outside the classroom is influenced by both the nature of the curriculum and resources and the students' own agency and learning beliefs. The study suggests that the focal L2 students took initiative by creating a Zone of Proximal Development (ZPD) outside of class to resolve linguistic problems they encountered in class. Conclusions Despite appearing as inexperienced language learners on the periphery, the focal international students demonstrated agency by employing diverse language learning strategies and channels. Additionally, some KSL students assumed expert and mediator roles and made significant contributions to local Korean communities.

Objetivo: Analisar como as pequenas e médias empresas (PME´s), aproximam-se da inovação frugal considerando os fatores diferenciais de agregar valor, otimizar processos, capital humano e modelo de negócios.
Método/abordagem: Pesquisa descritiva de casos múltiplos.  A análise dos dados coletados, seguiu o proposto por Gibbs (2009), considerando quatro fatores diferenciais, identificados na literatura, como norteadores categóricos para a interpretação dos resultados.
Principais Resultados: Aponta-se que os quatro fatores apresentados nesta pesquisa, representam um campo de possibilidades, não apenas no desenvolvimento de produtos e serviços frugais que atendem as necessidades dos clientes, mas de um processo maior, que estimulem as PME´s a se desenvolverem sustentavelmente, contribuindo para competitividade e maturidade nos negócios.
Contribuições teóricas/práticas/sociais: O estudo possibilita aos gestores a compreensão na identificação e desenvolvimento de suas capacidades organizacionais com o intuito de melhorar o negócio, permitindo, que as PME´s conquistem novos clientes, novos mercados, atuem com a limitação de recursos, reduzindo seus custos e aperfeiçoando seus processos.
Originalidade/relevância: O investimento em pesquisa empírica ao encontro das sugestões de estudos que argumentam a necessidade de avançar os debates existentes sobre a inovação frugal, principalmente em se tratando de empresas de pequeno e médio porte.

Introdução: O uso irracional de medicamentos isentos de prescrição médica é muito frequente na população, não sendo colocado em questão pelos usuários os riscos oferecidos, como: reações adversas, interações medicamentosas ou alimentícias e intoxicações.Objetivos: Entender quais os fatores que levam a população a fazer uso medicamentos de forma irracional.Métodos: Realizou-se uma revisão bibliográfica por meio de bibliotecas eletrônicas, SciElo e LILACS. A palavra chave para levantamento de pesquisa inicial foi “automedicação”, nos idiomas português e inglês.Os estudos identificados nas buscas iniciais foram avaliados de acordo com os critérios de inclusão: (1) desenho do estudo: estudo transversal, estudo descritivo, (2) público-alvo: população brasileira, jovem e adulta, (3) data de publicação: entre os anos de 2010 e 2022. Desenvolvimento: Foram 119 artigos encontrados nas bases de dados SciELO e LILACS, utilizando a palavra chave “automedicação” e aplicando o filtro de data de publicação para os anos 2010 a 2022. Destes, 91 foram excluídos pelo título, 7 por duplicidade e 9 pelo resumo. Foram lidos 12 trabalhos na íntegra, dentre os quais 7 foram selecionados para a revisão bibliográfica deste trabalho. Conclusão: É possível concluir com a análise dos trabalhos selecionados que há prevalência significativa de automedicação nas populações estudadas, sendo os analgésicos/antitérmicos com maior índice de relatos de uso

The COVID-19 pandemic has brought about many changes within the organization, including the aspects of compassion and employee communication which also affect employee performance. After this pandemic is over and transitioning into an endemic state, it is very important to do this research. The purpose of this study was to investigate how affection and communication between employees are elements that influence job satisfaction, employee commitment, and employee performance. The method of purposive sampling was utilized, and the sample consisted of 200 people totaling corporate employees in Jakarta. The sample was taken from the city of Jakarta. Quantitative and associative techniques are used in data processing, along with survey techniques and structural equation modeling. According to the findings of this study, compassion has no bearing on the performance of employees. On the other side, compassion is a factor in how satisfied one is in their employment and how committed they are to their profession. In a similar vein, communication among employees influences job happiness, devotion to one’s work, and performance on the job. In addition, there is a correlation between job happiness and employee performance, as is the case with work dedication, which also influences employee performance. The findings of this study provide an academic and practical overview that may be used to aid businesses in developing employee work commitment, employee job happiness, and employee performance during the period when the COVID-19 outbreak was occurring

Software architecture determines success or failure in the domain of
software development and design. As a system evolves, software
architecture erodes. This phenomenon is called architectural erosion.
Several studies that focused on various approaches to the problem of
architectural erosion have been conducted. As a direct consequence of
this, the metrics strategy has emerged as the most widely used solution
for architectural erosion. However, providing a comprehensive perception
of the elements required to evaluate the phenomenon of architectural
erosion with an acceptable level of quality is a challenge. The primary
goals of this research, which drew from the prior literature about
identifying architectural erosion, were to (1) determine whether various
adopted measures approaches determine architectural erosion in order to
develop a formal model, and (2) evaluate the construct reliability and
construct validity of the model. This research presents a model based on
the chosen measures approaches for identifying architectural
degradation. This model can be used as the cornerstone for a formal
definition of general approaches and adopted metrics. Data was collected
from 130 software engineering professionals with experience in
architecture erosion and software metrics via a questionnaire-based
survey. Structural equation Modelling (SEM) was used to analyse
construct reliability, construct validity, and research hypotheses. The
results demonstrate a substantial association between all metrics
approach classes and architectural erosion, except for architectural
complexity and architectural technical debt. Both researchers and
practitioners can significantly benefit from this model’s empirical
assessment and evaluation, which includes a valuable information in this
context.
