Application of NURBS in the Fracture Mechanics Framework to Study the Stress Intensity Factor
Authors: MONTASSIR Soufiane , MOUSTABCHIR Hassane , ELKHALFI Ahmed
Published: June 2023

In this investigation, we successfully employed the Non-Uniform Rational B-spline (NURBS) to study the fracture mechanics. the NURBS functions are very popular in the design field (CAD model) and it is used as an alternative to Lagrange interpolation polynomials. The extended isogeometric analysis based on this basis function is used to evaluate the stress intensity factors (SIFs) in order to control the crack propagation. For various crack lengths, SIFs were calculated to validate the accuracy of this technique. The results obtained are in good agreement with the available techniques as CFEM, X-FEM.
Analysis of The Progressive Damage of A Notched AS4/PEEK Composite Laminate Subjected To Tensile Loading
Authors: El idrissi Hamza , Seddouki Abbass
Published: June 2023

The purpose of this work aims to assess the failure of an open-hole composite laminate subjected to tensile loading, using different progressive damage approaches. Within Abaqus, a user-defined material subroutine (UMAT) was developed and implemented by applying a combination of Puck’s failure criterion and the gradual degradation model. In addition, the integrated model in Abaqus based on the Hashin failure criteria coupled with the continuous damage model has been also considered. Moreover, the effect of different specimen sizes on the behaviour of the AS4/PEEK composite laminate has been performed. The predicted results were compared to those available in the literature. The results of this comparative study showed good agreement between the experimental outcomes and the numerical predictions.

The Poisson-Topp-Leone Burr type-X II distribution is studied mainly for illustrating its wide applicability under uncensored engineering and medical real-life datasets. The real-life datasets are checked and analyzed for the statistical modeling purpose. The Poisson-Topp-Leone Burr type-X II model is compared with other nine types of Burr type-X II extensions and provided the best results. For modeling the bivariate uncensored engineering and medical real-life datasets, we presented some bivariate version with some useful theoretical results. Those versions are investigated due to certain and common copulas.
Feasible Stein-Type and Preliminary Test Estimations in the System Regression Model
Authors: Norouzirad Mina , Arashi Mohammad , Marques Filipe J. , Mamod Khan Naushad A.
Published: June 2023

In a system of regression models, finding a feasible shrinkage is demanding since the covariance structure is unknown and cannot be ignored. On the other hand, specifying sub-space restrictions for adequate shrinkage is vital. This study proposes feasible shrinkage estimation strategies where the sub-space restriction is obtained from LASSO. Therefore, some feasible LASSO-based Stein-type estimators are introduced, and their asymptotic performance is studied. Extensive Monte Carlo simulation and a real-data experiment support the superior performance of the proposed estimators compared to the feasible generalized least-squared estimator.
Inference Based on New Pareto-Type Records With Applications to Precipitation and Covid-19 Data
Authors: Nik A. Saadati , Asgharzadeh A. , Baklizi A.
Published: June 2023

We consider estimation and prediction of future records based on observed records from the new Pareto type distribution proposed recently by Bourguignon et al. (2016), “M. Bourguignon, H. Saulo, R. N. Fernandez, A new Pareto-type distribution with applications in reliability and income data, Physica A, 457 (2016), 166-175.”. We derived several point predictors for a future record on the basis of the first n records. Two real data sets on precipitation and Covid 19 are analysed and a Monte Carlo simulation study has been performed to evaluate the statistical performance of point predictors presented in this paper.
Reliability Estimation for the Inverse Weibull Distribution Under Adaptive Type-II Progressive Hybrid Censoring: Comparative Study
Authors: Alslman Majd , Helu Amal
Published: June 2023

The aim of this study is to investigate different methods of estimating the stress-strength reliability parameter, $\theta =P(Y<X)$, when the strength (X) and the stress (Y) are independent random variables taken from the inverse Weibull distribution (IWD), with the same shape parameter and different scale parameters. Based on Adaptive Type-II Hybrid progressive censored samples, we employ classical and Bayesian approaches. In the classical approach, we use the maximum likelihood estimator (MLE), the approximate maximum likelihood estimator (AMLE), and the least squares estimator (LSE). In contrast, the Bayesian approach utilizes symmetric and asymmetric loss functions. Due to the absence of explicit forms for Bayes estimators, we propose using Lindley's approximation method for computing the Bayes estimators. We compare these estimators using extensive simulations and two criteria: the bias and the mean square error (MSE). Finally, two real-life data examples are provided for illustrations.

Published: June 2023

We are mainly concerned with kernel-type estimators for the moment-generating function in the present paper. More precisely, we establish the central limit theorem with the characterization of the bias and the variance for the nonparametric recursive kernel-type estimators for the moment-generating function under some mild conditions in the censored data setting. Finally, we investigate the methodology’s performance for small samples through a short simulation study.

Authors: Alhamidah Alla , Naghizadeh Qmi Mehran , Kiapour Azadeh
Published: June 2023

In this paper, we consider the problem of E-Bayesian estimation and its expected posterior mean squared error (E-PMSE) in a Burr type XII model on the basis of record values. The Bayesian and E-Bayesian estimators are computed under different prior distributions for hyperparameters. The E-PMSE of E-Bayesian estimators are calculated in order to measure the estimated risk. Performances of the E-Bayesian estimators are compared using a Monte Carlo simulation. A real data set is analyzed for illustrating the estimation results.

Prediction of Characteristics Using a Convolutional Neural Network Based on Experimental Data on the Structure and Composition of Metamaterials
Authors: Zozyuk Maxim , Koroliouk Dmitri , Krysenko Pavel , Yurikov Alexei , Yakymenko Yuriy
Published: June 2023

This work proposes an algorithm for properties predicting metamaterials depending on their structure, physical properties of the components of metamaterials, and their characteristics. In this context, the term ”properties” means the result of interacting with the irradiation of a material with electromagnetic exposure of a certain frequency or spectral composition to determine the transmittance/reflection coefficients of the metamaterial. The model is based on the construction of metamaterial in form of a 3D object, the presentation of physical properties in the form of additional components in the object’s vectors, the presentation of experimental data in the form of polynomial coefficients, or the points on the chart of dependencies. Despite the small amount of data, a sufficiently small error rate was obtained for both cases, and the prediction results of experimental data are presented. The amount of experimental data can be increased by supplementary parameters which characterize the conditions under which the experimental data were obtained - polarization, angle of incidence, the intensity of irradiation, etc. The main issues may arise during the preparation of data for neural network learning due to difficulties in converting 3D formats into the required array of data and taking into account all the circumstances, dielectric and magnetic permeabilities, and specific conductivity.

D- And A- Optimal Orthogonally Blocked Mixture Component-Amount Designs via Projections
Authors: Husain Bushra , Hafeez Afrah
Published: June 2023

Mixture experiments are usually designed to study the effects on the response by changing the relative proportions of the mixture ingredients. This is usually achieved by keeping the total amount fixed but in many practical applications such as medicine or biology, not only are the proportions of mixture ingredients involved but also their total amount is of particular interest. Such experiments are called mixture amount experiments. In such experiments, the usual constraint on the mixture proportions that they should sum to unity is relaxed. The optimality of the design strictly depends on the nature of the underlying model. In this paper, we have obtained D- and A- optimal orthogonally blocked mixture component-amount designs in two and three ingredients via projections based on the reduced cubic canonical model presented by Husain and Sharma [7] and the additive quadratic mixture model proposed by Husain and Parveen [3], respectively.
Simultaneous Test for Means: An Unblind Way to the F-test in One-way Analysis of Variance
Authors: Elamir Elsayed A. H
Published: June 2023

After rejecting the null hypothesis in the analysis of variance, the next step is to make the pairwise comparisons to find out differences in means. The purpose of this paper is threefold. The foremost aim is to suggest expression for calculating decision limit that enables us to collect the test and pairwise comparisons in one step. This expression is proposed as the ratio of between square for each treatment and within sum of squares for all treatments. The second aim is to obtain the sampling distribution of the proposed ratio under the null hypothesis. This sampling distribution is derived exactly as the beta distribution of the second type. The third aim is to use beta distribution of second type and adjusted p-values to create adjusted points and decision limit. Therefore, reject the null hypothesis of equal means if any adjusted point falls outside the decision limit. Simulation study is conducted to compute type I error. The results show that the proposed method controls the type I error near the nominal values using Benjamini-Hochberg’adjusted p-values. Two applications are given to show the benefits of the proposed method.

POLITICAL CRITIQUE OF AXEL HONNETH'S RECOGNITION OF JURGEN HABERMAS' DELIBERATIVE DEMOCRACY
Authors: Sukrie Sukri , Antok Ishak
Published: June 2023

The purpose of this paper is to express Honneth's critique of Habermas' deliberative democracy. This research uses qualitative methods that are critically analytical in comparing the thoughts of Habermas and Honneth. The theory used is the sociology of knowledge from Karl Mannheim's. In the sociological theory of knowledge Mannheim says that man and his existence in the social environment can not be separated from his environment, a subjectivity that knows there is always interference from the social, political environment in which he lives. The results of this study reveal that the deliberative criticism of Democracy echoed by Habermas still leaves problems. The problem in deliberative democracies hints at rational communication, yet everyone does not have the same knowledge of rationality. For the educated person he has communication and knowledge rationally, but for the unlearned person does not have it, so they must represent his voice. In the Indonesian context, deliberative democracy is still wishful thinking. The public space referred to by Habermas has not yet gained a place in Indonesia, because the representation system that is the hallmark of representative democracy can be said to be pseudo-representation because there is no proportional bargaining position between constituents and their people's representatives. As Honneth's critique of Habermas the weakness of deliberative democracy, Honneth offers a form of intersubjective relation based on three areas of recognition namely love, self-confidence, self-respect, solidarity.

Semangat perjuangan keagamaan dapat diwujudkan dengan berbagai varian, lebih-lebih jika kepercayaan akan agama sudah mengakar sebagai spirit perjuangan. Agama telah menawarkan suatu cara pandang hidup yang mampu meng-cover setiap tindakan, perbuatan yang mengarah pada pembentukan manusia seutuhnya, demikian pula islam pada sisi-sisi kehidupan ummat baik dalam hal sosial, budaya, hukum bahkan politik sebagaimana yang telah dicontohkan oleh Nabi Muhammad SAW. Agama dan politik merupakan dua sisi yang terkadang dianggap bersebrangan. “agama” sebagai dasar berpolitik dalam melestarikan keyakinan yang dianut sering kali mengalami hambatan karena pemerintah terkadang menganggap sebagai batu sandungan yang mampu menggeser ketahanan kekuasaan seperti yang kita lihat pada masa aktivitas politik Syekh Zainuddin Abdul Majid, perjalanan politiknya semakit terlihat jelas pasca kemerdekan dengan mengikuti partai politik dan menentukan arah bangsa indonesia bagian timur hususnya pulau Lombok. Karir politik Syekh Zainuddin Abdul Majid dimulai sejak sebagai Konsulat Nahdlatul Ulama Sunda Kecil pada tahun 1950. Kemudian tahun 1952 menjadi ketua badan penasehat partai masyumi untuk daerah Lombok, hal ini karena nahdlatul ulama dan beberapa ormas lain tergabung dalam partai Masyumi.

Published: June 2023

Penelitian ini membahas larangan keterlibatan pegawai negeri sipil (PNS) dalam urusan politik sebagaimana diatur dalam Undang-Undang Nomor 5 tentang Aparatur Sipil Negara di Indonesia. Meskipun dilarang secara hukum, PNS sebagai makhluk politik memiliki dorongan untuk terlibat dalam politik, dan banyak individu yang memanfaatkan posisi dan fasilitas negara untuk memajukan karir mereka melalui cara politik. Penelitian ini bertujuan untuk mengeksplorasi bagaimana individu sebagai makhluk bebas memenuhi kebutuhan politik mereka sambil menjadi PNS dan menghadapi larangan keterlibatan politik. Studi ini menyimpulkan bahwa keterlibatan politik oleh PNS tidak dapat dihindari karena manusia adalah makhluk politik. Oleh karena itu, pemerintah perlu menjalankan sistem pemantauan dan penegakan yang lebih efektif untuk mengatur keterlibatan politik oleh PNS dan meningkatkan kesadaran mereka tentang pentingnya mempertahankan netralitas dan objektivitas saat menjalankan tugas mereka. Penelitian ini memberikan wawasan berharga tentang dinamika yang rumit dari keterlibatan politik oleh PNS dan menekankan perlunya penelitian lebih lanjut di bidang ini.

Published: June 2023

The issue of Islamic radicalism and terrorism in Indonesia in the last three decades has become a very serious problem. Not only in Indonesia, the phenomenon of terrorism in the Islamic world appears as an expression of the political movement of some Muslims who make use of Islamic doctrines, political attitudes and political movements that tend to be radical and extremist. By utilizing qualitative research procedures and data collection techniques through library research, this article draws several conclusions. First, international radicalism network named Al-Qaedah and Al-Jama’ah Al-Islamiyyah have influence over terrorist network in Indonesia and other Islamic worlds. The actors are alumni of the Afghan war and a network that been fostered since the 1970s through Al-Jamaah Al-Islamiyyah. Second, contemporary Islamic radicalism and terrorism movements in Indonesia have ideological-political connections with transnational Islamic movements and ISIS in two orientations namely the khilafah and the Islamic daulah. Third, in the socio-political area, a literalist understanding of the texts to fundamentalism. Finally, Islam often becomes a political commodity. Islamic doctrine often become tools to gain power of conversely also become tools to fight against power. This article recommends that the Indonesian government support moderate Islamic movements as counter-radicalism and terrorism measure.

Highlights:

It discusses the relationship between NLR and the severity of coronary atherosclerosis.
There is significant difference from the previous NLR research

Abstract:
Background. Neutrophil to Lymphocyte Ratio (NLR) is a marker of systemic inflammation correlated with the incidence of Coronary Artery Disease (CAD). Neutrophils infiltrate the coronary artery plaque causing acceleration of atherosclerosis. T lymphocyte recruitment is required at the early stages of plaque formation. Previous studies have shown that heightened NLR was correlated with the percentage of stenosis at the site of the multivessel lesion. Aims. This study aimed to determine the relationship between NLR with Gensini score of coronary arteries in CAD patients at Mataram City General Hospital. Material and method. This was a cross sectional study conducted in Mataram City General Hospital. Fifty-nine patients diagnosed with CAD participated in the study. Blood collection and coronary angiography were performed to assess NLR and Gensini Score. The main variables were NLR and Gensini Score. Gensini score of 1-29 was considered as mild atherosclerosis and Gensini score of 30 or more was considered as severe atherosclerosis. NLR was considered high if the value of NLR were > 2.385 based on previous studies. Spearman test was performed to assess correlation between variables. Results. Approximately 53% subjects were categorized as severe atherosclerosis and 48% as mild atherosclerosis. The median values of Gensini score in the low NLR group were 25.0 and in the high NLR group were 40.0 (p=0,19). The median values of NLR in the mild group of atherosclerosis were 1.78 and in the severe atherosclerotic group were 2.15 (p=0,59). There was no significant difference in NLR between severe atherosclerosis and mild atherosclerosis groups. NLR was not associated with Gensini score (p=0,32). Conclusions. There was no significant relationship between Neutrophil to Lymphocyte Ratio with Gensini score of coronary arteries in CAD patients at Mataram City General Hospital.

Highlights:

It discusses pediatric HCM which is usually caused by autosomal dominant traits caused by mutation in cardiac sarcomere protein genes.
It explains how to recognize the cardiac risk

Abstract:
Hypertrophic Obstructive Cardiomyopathy (HOCM) is a disease characterized by increased left ventricular (LV) wall thickness and accompanied by obstructive physiology measured by increased LV outflow tract gradient. It is mainly inherited in autosomal dominant traits caused by a mutation in cardiac sarcomere protein genes. In pediatrics, HOCM is rare and comprises a different diagnosis and management approach compared to adults. The risk of sudden cardiac death (SCD) is also higher in the pediatric population. Case Summary. This report is about a case of HOCM found incidentally in a 6-year-old boy and a discussion based on the latest literature review. The patient first came for evaluation for cardiac murmur and abnormality in ECG and chest x-ray. Diagnosis of HOCM was made through echocardiography assessment. Discussion. ICD implantation for primary prevention of SCD was considered based on individualized 5-year SCD risk assessment which is around 7%. Optimal pharmacological therapy with beta-blocker, careful planning of ICD implantation with balanced benefit and risk, and septal reduction surgery when indicated should extend the life expectancy and quality of life of pediatric HOCM. It is both essential and interesting to recognize pediatric HOCM diagnostic findings and to pursue further research about therapies of this rare disease.

Published: June 2023

Introduction: Dignity therapy is a brief psychotherapy that can reduce dignity-related distress and improve the quality of life for cancer patients. However, the experience of older patients is comparable to that of those with advanced cancer, little emphasis has been devoted. Aim: To evaluate and summarize the effectiveness of dignity therapy in managing elderly non-cancerous patients
 
Method: A mixed methods systematic review was conducted and assess their quality using the Joanna Briggs Institute's evaluation tools. 8 databases of literature including Cochrane Library, PubMed, SCOPUS, Web of Science, EMBASE, CINAHL(EBSCO), PsycINFO(OVID), and CBM were searched with search terms of “Dignity therapy” and “elderly”.
 
Results: 12 studies—3 RCTs, 5 qualitative studies, 2 mixed-methods studies, and 2 cross-sectional studies—out of 1615 studies were screened. Quantitative and qualitative results were separated into groups with quantitative groups containing the dignity-related distress, depression, and quality of life, and qualitative groups including remembrance of the past, meaning of life, pain of illness, and wishes for family members.
Conclusion: Evidence suggests that dignity therapy is beneficial and can be applied to non-cancer patients. The patient's baseline level of distress may affect outcomes, making it more difficult to intervene with patients if they are too distressed, but the effect may be less pronounced if the patient's distress level is low.

Authors: Arni Nur Rahmawati  , Ita Apriliyani  , Tri Sumarni
Published: June 2023

Introduction: Schizophrenia is a severe mental disorder characterized by decreased cognitive function and skills in social relations, inability to carry out self-care, and fulfilling the need for daily activities. The problems that occur in schizophrenic patients do not only affect the patients themselves, but also the families who care for the patients. Families have a burden in caring for schizophrenic patients. Families who are caregivers are vulnerable to stress which can affect their role as family companions. Various adjustments that must be faced in their role as caregivers are often a separate stressor, especially for families who lack adaptive coping skills. So that adaptive coping is needed to deal with stress and improve the psychological well-being of families in caring for schizophrenic patients. This study aims to determine the description of stress and psychological well-being in families who care for schizophrenic patients.
 
Method: This type of research is quantitative descriptive with a cross-sectional approach, carried out at the Kembaran I Purwokerto Health Center. The number of samples of families caring for schizophrenic patients was 30 using the total sampling technique. The research instrument was the Perceived Stress Scale (PSS) questionnaire consisting of 10 items and the Psychological Well-Being Scale (PWBS) consisting of 42 items. The analysis used is descriptive quantitative.
 
Result: The results of this study showed that most of the families who cared for schizophrenia patients had moderate stress levels are 28 families (93.3%) and moderate levels of psychological well-being in 25 families (83.3%).
 
Conclusion: Stressful conditions can affect the level of psychological well-being in families who care for schizophrenic patients. Psychoeducation is needed to help families choose appropriate coping strategies in dealing with stressors and improve their psychological well-being.

Pada masa pandemi COVID-19 ini diperlukan tindakan pencegahan dan pengendalian yang tepat, salah satunya adalah penggunaan masker. Penelitian ini ditujukan untuk mengetahui tingkat pengetahuan dan praktik terkait pembelian, penggunaan dan pengelolaan masker serta perbedaan pada pekerja publik non-kesehatan antara Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) level 1, 2, dan 3. Pengambilan data secara cross-sectional dilakukan dengan menyebarkan kuesioner secara daring dan luring kepada pekerja publik non-kesehatan di daerah PPKM level 1, 2 dan 3. Skor pengetahuan dan praktik dihitung dan dibandingkan dengan karakteristik demografi serta dilakukan analisis hubungan antara skor pengetahuan dan praktik. Sebanyak 182 pekerja publik non-kesehatan berpartisipasi dalam penelitian ini, dengan median (IQR) skor pengetahuan adalah 15,00 (4). Skor pengetahuan berhubungan signifikan dengan tingkat pendidikan terakhir (p=0,022) dan usia (p=0,036). Skor praktik dengan rata-rata 49,17±8,24 dan dikategorikan baik (skor>43) untuk 76,4% responden. Tingkat pengetahuan dan praktik pada daerah PPKM level 1, 2, dan 3 tidak berbeda secara signifikan. Skor pengetahuan berhubungan secara signifikan dengan skor praktik (p=0,000) dimana semakin tinggi skor pengetahuan maka skor praktik juga semakin tinggi. Pada penelitian ini dapat disimpulkan bahwa sebagian besar responden memiliki tingkat pengetahuan yang cukup dan praktik yang baik. Daerah tempat bekerja yang dikategorikan berdasarkan level PPKM tidak menimbulkan perbedaan yang signifikan terhadap tingkat pengetahuan dan praktik dari responden, sehingga tempat bekerja responden tidak mempengaruhi tingkat pengetahuan dan praktik dari responden. Terlepas dari pengetahuan dan praktik responden yang baik, tetap diperlukan penyuluhan mengenai pembelian, penggunaan dan pengelolaan masker yang baik sesuai panduan dari Kemenkes maupun WHO.
