Authors: Zhang Mingyang , Liu Con , Kujala Pentti , Hirdaris Spyros
Published: May 2024

The development of intelligent ship control systems in real-world conditions relies heavily on the accurate identification and prediction of ship seakeeping and maneuvering trajectories. In this study, we comprehensively evaluate a selection of deep learning methods to assess their learning capabilities in terms of idealizing ship motion behavior in realistic operational environments. To recover real conditions, we utilize historical Automatic Identification System (AIS) data and a time domain 6 Degree of Freedom (6- DoF) grounding dynamics model to generate ship motion sequences for a Ro-Ro passenger ship operating in the Gulf of Finland. Via a rigorous evaluation process, we validate the performance of these methods using extensive data streams. The analysis includes the identification and estimation of uncertainties between two ports. The paper demonstrates the proficiency of the selected deep learning methods in capturing ship maneuvering features, their potential use in the design of ship control and intelligent decision support systems.
Concept Design of Typhoon Power Generation Ship Using System Simulation
Authors: Mitsuyuki Taiga , Ebihara Haruki , Kado Shunsuke
Published: May 2024

A concept of a typhoon power generation ship for utilizing enormous typhoon energy is proposed. This paper developed a system simulator for evaluating and designing the concept of a typhoon power generation ship using typhoon track history. A developed simulator was applied to the case study to design a typhoon power generation ship ship that operated near Japan. The case study showed that the annual power generation of the typhoon power generation ship tends to saturate and become constant earlier when the number of typhoons is small, in contrast to the improvement of power storage capacity. This result indicates that the appropriate size of the typhoon power generation ship exists at the current technology level.
C-ShipGen: a conditional guided diffusion model for parametric ship hull design
Authors: Bagazinski Noah J. , Ahmed Faez
Published: May 2024

Ship design is a complex design process that may take a team of naval architects many years to complete. Improving the ship design process can lead to significant cost savings, while still delivering high-quality designs to customers. A new technology for ship hull design is diffusion models, a type of generative artificial intelligence. Prior work with diffusion models for ship hull design created high-quality ship hulls with reduced drag and larger displaced volumes. However, the work could not generate hulls that meet specific design constraints. This paper proposes a conditional diffusion model that generates hull designs given specific constraints, such as the desired principal dimensions of the hull. In addition, this diffusion model leverages the gradients from a total resistance regression model to create low-resistance designs. Five design test cases compared the diffusion model to a design optimization algorithm to create hull designs with low resistance. In all five test cases, the diffusion model was shown to create diverse designs with a total resistance less than the optimized hull, having resistance reductions over 25%. The diffusion model also generated these designs without retraining. This work can significantly reduce the design cycle time of ships by creating high-quality hulls that meet user requirements with a data-driven approach.

Authors: Benson Simon , Skanda Ali , Shafii Hassan , Elleke Katharina , Scott-Harden Simon , Smith Nathan , Birmingham Richard , Pabari Dipesh
Published: May 2024

Flipflopi is an East African organisation with a mission to end single use plastic, driving this agenda using circular economy principles applied to the design and build of fully recycled plastic sailing dhows from their boatyard in Lamu Kenya. Flipflopi has achieved measurable global impact by showcasing the world’s first ocean going recycled sailing boat, Ndogo, a 9 metre long, lateen rigged dhow which has sailed the East African coastline and across Lake Victoria. Flipflopi is now aiming to build a much larger ocean-going dhow, named Kubwa, which presents further technical challenges from a marine design perspective. To meet these challenges. Flipflopi are utilising a combination of generational heritage boatbuilding expertise in Lamu; specific design experience from building and sailing Ndogo; technological progress driven by other recycled plastic projects; and more formalised naval architecture and engineering design approaches. This paper introduces the context within which Flipflopi is centred, the links to circular economy design principles and the specific design challenges from working with recycled plastic as a boatbuilding material.
Pushing and Establishing New Frontiers: An Examination of Publication Patterns From 2015-2023 in the Journal of Student-Run Clinics
Authors: Nguyen Oliver T , Rumenapp Joseph C , Lee David , Patel Hardik , Chen Kevin , Major Kendall
Published: May 2024

Background: The Journal of Student-Run Clinics (JSRC) has published research from student-run clinics (SRCs) for almost ten years. However, to date, no study has aimed to summarize publishing trends observed at JSRC. Thus, we aimed to characterize these JSRC publications in order to identify patterns in published research topics, identify research gaps, and inform future research priorities.
Methods: We adapted scoping review methodology and included all articles published in the JSRC from 2015 to 2023. For each article, we assessed for publication year, article type, university affiliated with the SRC, region of the United States (US) the SRC is located in, disease focus, outcomes studied, data collection methods used, sample size, interventions involved, analytic approaches used, and concept domains involved. Concept domains were determined using a taxonomy from the Agency for Healthcare Research and Quality (AHRQ) to identify patterns in topical content from published articles.
Results: This review included 167 articles. Over time, we observed an increasing trend of overall publication volume (e.g., 5 in 2015 vs 23 in 2023). Studies typically occurred in the primary care context with fewer studies in other outpatient specialties (e.g., ophthalmology, physical therapy). The most common domains were workforce (21.3%), workflows (17.4%) and practice/quality improvement (17.4%). Empirical studies typically used surveys (52.1%) or chart reviews of patient records (38.5%) for data sources. Less than half of the studies aimed to assess the impact of an intervention.
Conclusion: This review highlighted significant strides made on research in SRCs. Future studies reporting intervention may benefit from adhering to established reporting guidelines. Additional studies are needed across several areas, including understanding the impact of non-primary care SRCs, assessing quality of care and clinical outcomes, and employing qualitative and/or mixed methods approaches when studying interventions’ impact on patients and volunteers.
Making The Best Use Of Ads In Flipped Classroom For Improving Critical Reading Comprehension
Authors: Gul Dr. Muhammad Asif , Ahmad Riaz
Published: May 2024

Modern pedagogy emphasizes strongly on interactive learner-centred teaching and Flipped Method is fast becoming popular in language teaching programs. The language of ads, being rich in its ideational, interpersonal and textual meanings, offers ample resources for improving critical reading ability. This study attempts to blend these two important phenomena of modern life: Flipped Method and advertisements. Considering the richness of the ad’s language, the researcher conducted this exploratory study and showed that the analyses of the ad’s language on the three levels of Hallidayan paradigm can greatly improve learners’ critical comprehension ability. T[1]he research relies heavily on Dell Hymes’s idea of language as a social construct. The researcher’s objective was to explore how far the Critical Discourse Analyses of ad’s linguistic elements can enhance the critical reading ability of the learners if the attempt exploits the advantages of Flipped Method. The linguistic analyses of two ads on the theoretical framework of Halliday indicated that the linguistic resources are exploited dexterously to achieve the desired locution, ill-locution and perlocution and the successful readers can improve their critical skill through interactive analyses of ads.
Quality of care in severe maternal morbidity in a referral hospital in Kenya
Authors: CHEMWEY RN , OKUTOYI KL
Published: May 2024

Background: Studying cases of near miss or severe acute maternal morbidity are increasingly recognized useful  measures in implementation of quality obstetric care. 
Objective: To describe the quality of care in severe maternal outcomes at Kenyatta National Hospital.
Method: This was a prospective mixed method study design done from the Reproductive Health, Accident and  Emergency, Renal Unit and Critical Care Unit of Kenyatta National Hospital. Two hundred and twenty eight health  records of patients with severe maternal outcomes and key informant interviews were performed via simple  random sampling. Data was entered into STATA checked for completeness, errors and outliers. Summarized data  were presented in tables, graphs and charts. 
Results: All 5 units assessed had required resources to provide comprehensive Emergency Obstetric Care and  specialized care to patients diagnosed with severe maternal morbidity. Peer reviews were mostly done through  inter departmental consultations. There was no clear reward mechanism for good work done, however, disciplinary  measures were well outlined through relevant committee. Adherence to standard operating procedures was  generally poor and deteriorating over the time of the study.  
Conclusion: Gaps exist in comprehension of standard operating procedures while managing severe maternal  morbidity at Kenyatta National Hospital despite this hospital having resources for better services. We recommend  regular and scheduled clinical audits of severe maternal morbidity followed with feedback to clinicians to facilitate  better use of evidence based guidelines.

Authors: MUGAMBI JW , CHEMWEY RN , ONDIEKI DK
Published: May 2024

Malignant Fibrous Histiocytoma (MFH) is a soft tissue sarcoma usually involving limbs and retroperitoneum. MFH  of the anterior abdominal wall is rare with a high recurrence rate. Though wide surgical excision is the mainstay of  treatment, it creates large abdominal wall defects that need reconstruction. The addition of chemotherapy and  radiotherapy optimize the chances of survival and cure. We report a case of twice recurrent pleomorphic spindle cell  sarcoma of the anterior abdominal wall in pregnancy, with adverse maternal and fetal outcome.

Authors: KINUTHIA K , MAOGOTO E , KARUGA J
Published: May 2024

Introduction: A calcified endometrial mass is a worrying finding in a postmenopausal patient, warranting urgent  intervention. This case highlights an interesting presentation of a Lippes loop that has grown into an endometrial  polyp, raising suspicion that it may have been a malignancy.  
Case presentation: This is a case of a 70 year old multiparous patient who presented with history of chronic pelvic  pain. She could not recall insertion of the Lippes loop, and had therefore never sort to have it removed. 
Management and outcome: The patient underwent total abdominal hysterectomy and bilateral salpingo oophorectomy. She made a complete recovery, and histology revealed a calcified endometrial polyp.
Conclusion: The Lippes loop is no longer inserted and is becoming a rare find in the practice of gynaecology. This  case was an usual presentation of a Lippes loop, as the endometrial polyp had grown around the Lippes loop giving  the impression of a calcified endometrial lesion.

Multi Level Marketing From A Sharia Economic Perspective
Authors: Ana Siti Parida Dwi Yuliantika  , Alda Maulidy  , Asnah  , Siva Anis Sabina
Published: May 2024

Multi-level marketing (MLM) is a business model in which a company sells products through a network of independent distributors. From a sharia economic perspective, MLM often causes debate because some of its practices can be questioned from a sharia compliance perspective. First of all, MLM emphasizes the aspect of buying and selling products, which is in line with sharia economic principles which encourage legitimate business activities and avoid usurious or speculative transactions. However, many MLMs face criticism because they tend to focus more on recruiting new members than actual product sales. This is contrary to sharia principles which emphasize justice and honesty in business. Second, in MLM, there is an element of profit sharing which is usually disproportionate between the company, distributors and network members. In sharia economics, the distribution of profits must be fair and balanced, and practices that cause injustice in the distribution of profits must be avoided.
Pachamama y el dios del jubileo bíblico en la dialéctica de la opresión-liberación.
Authors: , docente universitario e investigador. Dr. Calixto Huanca Cárdenas
Published: May 2024

El presente artículo es un intento de desentrañar, el sujeto social bíblico que es el pueblo de Israel primero, luego la comunidad cristiana, creyente y pobre, que vive la experiencia de la fe en Jesucristo resucitado tal como testimonia el Evangelio de Lucas en el Nuevo Testamento.  En este sentido, el sujeto social bíblico es una manera de entender el sujeto social del Dios Pachamama en la historia de la cultura inca; porque son dos sujetos sociales que viven la experiencia de la fe en un Dios supremo, pero en circunstancias históricas distintas, en el espacio geográfico también diferente y valores culturales propios.
El Dios opresor y de la muerte de la cristiandad colonial, es el Dios distorsionado, manipulado e instrumento de los conquistadores, invasores coloniales y de los criollos sociales dominantes de la Republica.   Por lo tanto, el Dios de la Biblia no es el opresor colonial, tampoco lo es el Dios Pachamama, sino es un Dios que lucha en la resistencia contra todo tipo de la opresión económica, política, social, cultural y religiosa.

Published: May 2024

El envejecimiento poblacional demanda estrategias efectivas para fomentar la salud y el bienestar en adultos mayores, centrando la importancia de la actividad física como pilar fundamental para la prevención y tratamiento de enfermedades. Este estudio evalúa los efectos del ejercicio aeróbico y el entrenamiento de resistencia en marcadores biológicos clave para la salud geriátrica, destacando la necesidad de programas personalizados que respondan a las necesidades únicas de este grupo demográfico. Para garantizar la fiabilidad de los resultados, se siguieron rigurosas metodologías, incluida la revisión sistemática basada en el protocolo PRISMA, metaanálisis y evaluaciones cualitativas y cuantitativas para controlar sesgos. Los hallazgos indican que, mientras el ejercicio aeróbico mejora la función cardiovascular y los perfiles metabólicos, el entrenamiento de resistencia preserva la función muscular y previene la sarcopenia. La investigación revela la necesidad de combinar ambas formas de ejercicio en intervenciones destinadas a mejorar la salud de los adultos mayores, abriendo futuras líneas de indagación sobre personalización de los programas de ejercicio. El análisis concienzudo de estudios científicos apoya la implementación tanto del ejercicio aeróbico como del entrenamiento de resistencia en programas dirigidos a los adultos mayores, subrayando impactos significativos en salud musculoesquelética y cardiovascular. La investigación insta a la práctica clínica a fomentar actividades físicas adaptadas al perfil individual del mayor, con miras a un envejecimiento activo y saludable. La metodología rigurosa y la falta de sesgo en los resultados refuerzan la validez de recomendar ejercicios mixtos para la mejora integral de la condición biológica en la tercera edad.
Impacto de la actividad física en la prevención de enfermedades cardiovasculares: un análisis sistemático
Authors: Aguirre Chávez Juan Francisco , Franco Gallegos Leticia Irene , Montes Mata Karla Juanita , Ponce de León Alejandra Cossío , Robles Hernández Guadalupe Simanga Ivett
Published: May 2024

La revisión sistemática y metaanálisis realizada enfatizan la importancia crucial de la actividad física en la prevención de enfermedades cardiovasculares (ECV), principales causas de morbilidad y mortalidad a nivel mundial. La investigación incluyó la selección meticulosa de 16 estudios, abarcando diseños metodológicos variados como ensayos controlados aleatorizados, estudios de cohorte y transversales, los cuales revelaron consistentemente que el ejercicio regular reduce marcadamente el riesgo de patologías cardíacas. Este análisis destacó una relación dosis-respuesta entre la actividad física y las ECV, sugiriendo que mayores niveles de ejercicio están asociados con una menor frecuencia de eventos cardiovasculares adversos. Una actividad aeróbica de intensidad moderada a alta, combinada con ejercicios de resistencia durante al menos 150 minutos semanales, mostró la máxima eficacia preventiva. La universalidad de los efectos beneficiosos de la actividad física se demostró en diversos subgrupos poblacionales, pero también se reconoció la necesidad de personalizar las recomendaciones basándose en factores demográficos específicos para optimizar su efectividad preventiva. Los hallazgos apoyan el desarrollo de políticas públicas y estrategias de salud que promuevan estilos de vida activos, accesibles y seguros para todos. La investigación futura deberá continuar explorando la relación entre la actividad física y la salud cardiovascular para establecer pautas de ejercicio óptimas y maximizar los beneficios preventivos del ejercicio en poblaciones diversas. Estos descubrimientos subrayan la actividad física como un componente esencial y universalmente beneficioso en la prevención de ECV, meritorio de inclusión prioritaria en el diseño de programas de salud pública.
Paradoxo democrático no controle judicial de constitucionalidade
Authors: Vinagre Augusto dos Santos Nathan
Published: May 2024

O presente trabalho busca verificar se seria cabível a mitigação do paradoxo democrático constante no controle concentrado de constitucionalidade. Inicialmente, o artigo apresenta os aspectos benéficos do controle de constitucionalidade para o Estado Democrático de Direito, abordando a questão da harmonização dos poderes e da proteção dos direitos fundamentais, uma vez que tais matérias são cruciais para a preservação das democracias modernas. Entretanto, por mais que o controle possua caraterísticas indispensáveis para o exercício democrático, a extrapolação dessa competência constitucional acarreta crises de legitimidade, seja pela utilização de embasamento político no momento da realização da decisão ou de interpretação criativa, valendo-se de valores morais, como argumentação jurídica. Nesse aspecto, conclui-se que o desenvolvimento de metodologia de decisão jurídica, com preceitos de atuação melhores delineados, diminuiria eventuais crises democráticas nas decisões proferidas. Ademais, a organização legislativa com o efetivo acompanhamento e realização de relatórios sobre os julgamentos da Suprema Corte corroboraria com a ideia de mitigar os impactos democráticos da decisão judicial, ao constitucionalizar a questão por intermédio de emendas constitucionais.
Design Algorithm for Sequential Pneumatic and Electropneumatic Systems
Authors: Ordaz Oliver Mario Oscar , Gutiérrez-Moreno Evelin , Ordaz Oliver Jesús Patricio , Hernández-P´érez Javier , Santos Sánchez Omar Jacobo
Published: May 2024

This article presents an alternative automation algorithm for pneumatic sequences that enables the solution of complex sequential problems without the need to organize detection phases into groups. By not using groups to organize movements in detection phases, two benefits can be achieved: firstly, all the drawbacks associated with using groups are eliminated, such as design complexity, difficulty in debugging, increased cost, and difficulty in optimizing the circuit; secondly, it enables the use of logical functions to define each motion in pneumatic actuators. This opens up the possibility to solve logical functions using Boolean algebra techniques, and even their generalization into an algorithm that can be programmed in any language. To validate the proposed algorithm, MATLAB pseudocode is presented. This pseudocode allows obtaining the logical functions needed to build the ladder diagram of any sequence involving up to four double-acting cylinders with any number of phases in a work cycle.

Authors: Leiva Vasconcellos Marcos A. , Tovar Vidal Mireya
Published: May 2024

The analysis of the polarity of various types of comments has been enhanced by the development of Web 2.0, where millions of user-generated opinions on different sites now offer a wealth of information. Opinion mining focuses on automatically determining the polarity of posts for research and the development of real-world applications. This article aims to determine which of the proposed algorithms (Decision Trees, Support Vector Machine, Naïve Bayes, and Convolutional Neural Network) are most suitable for predicting the polarity of opinions in the tourism domain. For this purpose, a set of opinions (30,210) from the REST-MEX 2022 Sentiment Analysis competition, pertaining to hotels, attractions, and restaurants, is used. The experimental results obtained show that the Convolutional Neural Network (CNN) is the best classifier, achieving an accuracy of 98.83%, followed by the Support Vector Machine (SVM) and Naïve Bayes with accuracies of 71% and 70% respectively. The worst performance was observed with Decision Trees, which achieved 62% accuracy.
Relationships Between Eating Disorders, Depression and Suicidal Tendencies Among Adolescent Girls from Arab Society
Authors: Zubeidat Ihab
Published: May 2024

This study aimed to find the possible links between eating disorders among adolescents and the dimensions of depression and suicidal tendencies, as reported by them. The sample consisted of 200 adolescents from Arab society in the north of Israel. The research tools included a socio-demographic questionnaire; the Eating Attitudes and Behaviors Questionnaire; the Beck Depression Inventory; and the Multidimensional Suicidal Tendencies Questionnaire for Adolescents. Findings suggest a positive relationship between eating disorders and depression and suicidal dimensions among female adolescents, and a significant relationship between eating disorders and the attraction and repulsion toward life. In addition, female adolescents reported very high levels of attraction to life and repulsion to death; namely, participants reported very low levels of attraction to death and medium-scale repulsion to life. A positive relationship was also found between the dimensions of depression and suicidal tendencies among the participants. Additional findings indicate that underachiever adolescents reported lower levels of depression and higher levels of attraction to life, compared with the average achievement teenagers. The obvious conclusion is that, since depression is the main predictor of suicidal tendencies among teenagers, rather than focusing on the consequences of depression, we should focus on the causes of depression and treat them.

The purpose of this study was to compare the perception of the teaching-learning climate in university students of two modalities in a pedagogy program. From a quantitative, comparative, descriptive, inferential and prospective approach, it considered a random sample of 194 students, distributed according to the study regime. The Enabling Learning Teaching Climate Scale (ECAFEU) was used. In both regimes, the dominant dimension is autonomous learning, and the descended dimension is environmental conditions. High scores were observed in both tests of the ECAFEU Index; However, the data provide considerable differences regarding the centrality of the teaching and learning process.

Authors: Sadeghi Nia Kimia , Asmaee Majd Sirvan
Published: May 2024

e present study aimed to compare the defensive mechanisms and suicidal thoughts among substance-dependent men and women. The research design was a retrospective (causal-comparative) study. The sample included 112 substance users (56 women and 56 men) from addiction rehabilitation centers in Gilan province, selected through convenience sampling based on entry criteria for this study. Two questionnaires were used in this study: the Defense Style Questionnaire (DSQ-40) and the Beck Scale for Suicide Ideation (BSSI). The collected data were analyzed using multivariate analysis of variance with SPSS software version 26. Data analysis showed no significant difference in the defensive mechanisms between men and women dependent on substances; however, there was a significant difference in suicidal thoughts between men and women dependent on substances. Considering the results of this study, therapists and counselors working with substance-dependent individuals are advised to pay attention to the defensive mechanisms and suicidal thoughts of these individuals, as awareness of these variables can assist in providing better and more appropriate services to these patients.
Pseudo-BI-algebras‎: ‎Non-commutative generalization of BI-algebras
Authors: Radfar A. , Rezaei A.
Published: May 2024

We ‎define and study the pseudo BI-algebras as a generalization of BI-algebras and implication algebras and investigate some properties‎. Also‎, ‎we define distributive pseudo BI-algebras and construct a BI-algebra related to these‎. ‎Further‎, ‎we prove ‎there is no proper pseudo BI-algebra of the order less than 4 and that every pseudo BI-algebra of order 4 is a poset‎, ‎and so is a pseudo BH-algebra‎. ‎‎Beside‎, ‎we introduce exchangeable pseudo BI-algebra and show that the class of them is a proper subclass of the class pseudo CI-algebras‎. ‎Finally‎, ‎we define the notions of (weak) commutative pseudo BI-algebras and prove ‎every weak commutative pseudo BI-algebra is a (dual) pseudo BH-algebra‎, ‎but the converse is not true‎, ‎and show that every exchangeable commutative pseudo BI-algebra is an implication algebra.
Quotient bipolar fuzzy soft sets of hypervector spaces and bipolar fuzzy soft sets of quotient hypervector spaces
Authors: Dehghan O.R.
Published: May 2024

In this paper, two related quotient structures are investigated utilizing the concept of coset. At first, a new hypervector space F/V = (F/V,\circ,\circledcirc,K) is created, which is composed of all cosets of a bipolar fuzzy soft set (F;A) over a hypervector space V . Then it will be shown that dim F/V = dim V/W, where the quotient hypervector space V/W includes all cosets of an especial subhyperspace W of V. Also, three bipolar fuzzy soft sets over the quotient hypervector space V/W are presented and in this way some new bipolar fuzzy soft hypervector spaces are defined.
Ideals of roughness in L-algebras
Authors: Shirvani Bourojeni M.
Published: May 2024

Rough is an exceptional mathematical tool for effectively analyzing and addressing the complexities of vague action descriptions in decision problems. This paper explores the concept of an L-algebra, which leads to the introduction of lower and upper approximations. The properties of these approximations are also discussed and elucidated. Furthermore, it is proven that the lower and upper approximations serve as interior and closure operators, respectively. Additionally, by employing A-lower and A-upper approximations, this paper presents and examines conditions for a nonempty subset to be definable. Furthermore, we investigated the circumstances under which the A-lower and A-upper approximations can be rough ideals. Finally, we define an operation ‎" -->"‎ on the set of all upper approximations of L ‎and ‎prove ‎that ‎it ‎is ‎made ‎an ‎‎L-algebra.
An algebraic study of LB-valued general fuzzy automata: On the concept of the layers
Authors: Abolpour kh. , Shamsizadeh M.
Published: May 2024

The present study aims at introducing a new concept of layer of LB-valued general fuzzy automata (LB-valued GFA) where B is regarded as a set of propositions about the GFA, in which its underlying structure has been a lattice-ordered monoid. In general, it demonstrates that the layer plays a key role in the algebraic study of LB-valued GFA by characterizing the concepts of subautomata and separated subautomata of an LB-valued GFA in terms of its layers. In other words, it highlights that every LB-valued general fuzzy automaton has at least one strongly connected subautomaton. In specific, the characterization of some algebraic concepts such as subautomaton, retrievability and connectivity of an LB-valued GFA in terms of its layers is provided. In addition, it is shown that the maximal layer of a cyclic LB-valued general fuzzy automaton and minimal layer of a directable LB-valued general fuzzy automaton are unique. Finally, we investigate the different poset structures associated with an LB-valued general fuzzy automaton, demonstrating some of these posets as finite upper semilattice, and introducing the isotone Galois connections between some of the pairs of the posets/finite upper semilattices introduced.
Strongly Regular Relations Derived from Fundamental Relation
Authors: Afshar B. , Ameri R.
Published: May 2024

We introduce a new regular relation δ on a given group G and show that δ is a congurence relation on G, with respect to module the commutator subgroup of G. Then we show that the effect of this relation on the fundamental relation β is equal to the fundamental relation γ, and we conclude that, if ρ is an arbitrary strongly regular relation on the hypergroup H, then the effect of δ on ρ, results in a strongly regular relation on H such that its quotient is an abelian group.
Zero Divisor Graphs Based on General Hyperrings‎
Authors: Hamidi M.
Published: May 2024

This paper introduces the concepts of reproduced general hyperring and valued-orderable general hyperring and investigates some properties of these classes of general hyperrings‎. ‎It presents the notions of‎ ‎zero divisors and zero divisor graphs are founded on the absorbing elements of general hyperrings‎. ‎General hyperrings can have more than one zeroing element‎, ‎and therefore‎, ‎based on the zeroing elements‎, ‎multiple zero divisors can be obtained‎. ‎In this study‎, ‎we discuss the isomorphism of zero divisor graphs based on the diversity of divisors of zero divisors‎. ‎The non-empty intersection of the set of absorbing elements and the hyperproduct of zero divisors of general hyperrings play a major role in the production of zero divisor graphs‎. ‎Indeed it investigated a type classification of zero divisor graphs based on the finite general hyperrings‎. ‎We discuss the finite reproduced general hyperrings‎, ‎investigate their zero divisor graphs‎, ‎and show that an infinite reproduced general hyperring can have a finite zero divisor graph‎.

Published: May 2024

Objective: Love Trauma Syndrome encompasses a range of severe symptoms that emerge after the end of a romantic relationship and are sometimes accompanied by a spectrum of clinical conditions such as severe anxiety, depression, and substance use. Therefore, the present study aims to investigate the effectiveness of cognitive-behavioral therapy (CBT) on self-esteem, anxiety, and depression in female university students with a history of emotional breakup. Methods and Materials: This quasi-experimental research employed a pre-test, post-test, and follow-up design with a control group. The statistical population included all female students at Sari University who visited the counseling center in 2023. A purposive and convenience sampling method was used, selecting students who had a history of emotional breakup and were willing to participate voluntarily. A total of 30 eligible participants were randomly assigned to either the intervention or control group. Research instruments included the Love Trauma Inventory (LTI), Beck Depression Inventory-II (BDI-II), Rosenberg Self-Esteem Scale, and Beck Anxiety Inventory, all of which were completed by both groups in the pre-test, post-test, and follow-up stages. Data were analyzed using SPSS.22 software, and multivariate and univariate covariance analyses were conducted. Findings: The results indicated that cognitive-behavioral therapy was effective in improving symptoms of Love Trauma Syndrome (F = 230.28, P < 0.001), self-esteem (F = 134.18, P < 0.001), anxiety (F = 136.51, P < 0.001), and depression (F = 715.32, P < 0.001) in female university students, with these results being sustained through the follow-up period. Conclusion: It can be concluded that cognitive-behavioral therapy is effective in reducing the symptoms of Love Trauma Syndrome, decreasing anxiety and depression, and increasing self-esteem.
