Published: April 2024

OBJECTIVES This study aimed to investigate the knowledge and perceptions of menopause among post-menopausal women.METHODOLOGYA descriptive cross-sectional study was conducted at Hayatabad Medical Complex, Medical, and Teaching Institute Peshawar from March 2022 to March 2023. Participants meeting the inclusion criteria were assessed using a semi-structured proforma covering demographic variables, knowledge, and attitudes toward menopause. Delving into knowledge and perceptions of menopause, the questionnaire probed participants about their awareness of menopause upon cessation of menstrual periods, knowledge of the age of menopause, understanding of menopausal symptoms, whether they perceived menopause as a disease, medical condition, or a natural process, and their opinions on the treatment of menopausal symptoms.RESULTSIn a survey assessing menopausal characteristics and perceptions, 81% of women experienced natural menopause and 19% underwent surgical menopause. 85% had prior knowledge of menopause, but only 45% knew its typical onset age. 56% held a positive perception of menopause. Hot flashes and mood swings were reported by 55% of women, while 48% experienced insomnia.CONCLUSIONMany post-menopausal women are not aware of menopausal symptoms. Tailored health education and comprehensive support are necessary to address knowledge disparities and provide holistic care for women in this transition.

Published: April 2024

Descrito por primera vez por Friedrich Ernst Krukenberg en 1896, el tumor de Krukenberg es un adenocarcinoma de ovario metastásico de células en anillo de sello. La incidencia del tumor de Krukenberg oscila entre el 1% y el 21%. Los sitios de tumores primarios más comunes para las metástasis ováricas son el estómago, que generalmente surge del píloro, seguido del colorrectal, la mama y el apéndice. En aproximadamente el 70% de los casos, el estómago se considera el sitio principal. Estos síntomas son inespecíficos, ya que en el 30% de los casos pueden ser la primera manifestación de un tumor primario, pero en otros casos son un hallazgo intraoperatorio incidental; a menudo presentan un dilema diagnóstico, especialmente cuando sirven como presentación inicial cuando no se ha encontrado ningún tumor primario. Existe poca investigación sobre esta enfermedad, que se considera de mal pronóstico y rápida progresión, por lo que el presente reporte de caso es de gran importancia. Se presenta una paciente femenina en gestación más diagnóstico de diabetes gestacional y examen de imagen eco obstétrico se evidencia masa pélvica.

Modelo de Huelga General. Una Aproximación a la Teoríade Juegos
Authors: Rios Barrios Luis Dario
Published: April 2024

En los últimos años, la economía a nivel global se enmarca en grandes transformaciones en la propia estructura productiva, como consecuencia de la aplicación de la inteligencia artificial (AI) y la automatización industrial. Este proceso, traerá consigo tensiones laborales que involucrará grandes movilizaciones del factor trabajo a fin de mantener sus espacios y derechos conquistados durante décadas. Este artículo científico pretende determinar los factores que influyen en el éxito o fracaso de una huelga general, en un contexto en el que el Gobierno busca maximizar el crecimiento económico con el objetivo de mantener el poder, mientras que el Líder sindical busca maximizar la cantidad de afiliados a su organización que le permita presionar al Gobierno y obtener espacios de poder. La presenta publicación se centra en la formulación de un modelo de huelga como una aproximación a la Teoría de Juegos, que permita hallar un Equilibrio de Nash que refleje las realidades de ambos jugadores. El Equilibrio de Nash Perfecto en Sub-Juegos (ENPS) demuestra finalmente que la única variable relevante en el éxito o fracaso de la huelga es el talento, habilidad o capacidad del Líder Sindical de movilizar la mayor cantidad de trabajadores sin que esto afecte el correcto funcionamiento de la economía y, por ende, de los salarios reales que el Gobierno se compromete a otorgar.

Development of the Czech Armed Forces Doctrinal Framework
Authors: Žižka Pavel , Saibert Richard
Published: April 2024

The article deals with the system of joint doctrine development in the Czech Armed Forces (CAF) focused on the operational level of command and control, including the implementation of the NATO doctrines into national conditions. Among others, it was found that the structure and content of the Czech doctrines are not systematically set. Allied doctrines are introduced either by rewriting them into the Czech version or by introducing them in the full English version. In both cases, it might cause inconsistency in military terminology. The Coordinating Committee as the only supervisory body does not have the authority to streamline the process of producing military publications. The most important paper recommendations include alignment of the Czech doctrinal framework with the NATO architecture, adoption of Allied doctrines in the English version including the national specifics, or redistribution of competencies within the processing group. Notwithstanding, the above-mentioned proposals, which indicated high impact, require crucial steps to be taken to implement them.

Conceptron: Framework para desenvolvimento de redes neurais artificiais
Authors: Machado da Silva Jordan Alexander , Gabriel Amado Felipe
Published: April 2024

A inteligência artificial é um segmento da computação, que possibilita a criação de sistemas capazes de reproduzir a habilidade humana de pensar e resolver problemas. Dentro desta ramificação, existem as redes neurais artificiais, que podem ser definidas como programas, compostos por vários nós, ou neurônios, que são interligados e trocam informações de forma constante. Cada camada desses neurônios executa um algoritmo nos dados processados, atribuindo à rede a capacidade de reconhecer padrões e correlações, agrupar e classificar dados, ou ainda, aprender a realizar alguns tipos de tarefas. Muitas pessoas associam a criação de uma rede neural artificial diretamente com o desenvolvimento de software, o que pode se tornar uma barreira para quem esteja iniciando o aprendizado em inteligência artificial ou algum profissional de outra área, que queira aplicar esses modelos em seus estudos. Este trabalho tem como objetivo apresentar o desenvolvimento de um framework que facilita a criação de modelos de redes neurais artificiais, utilizando uma interface gráfica simples e didática, feita com ReactJS e Node.js, que permite a visualização da representação gráfica da rede neural e a geração do código fonte desse modelo. O código apresentado é escrito em Python e utiliza os algoritmos e abstrações da biblioteca PyTorch, podendo ser utilizado para o aprendizado ou acoplado em outras aplicações.
Mineração de dados para comparação dos padrões de compras em uma rede de supermercados do oeste do Paraná antes e durante a pandemia de COVID-19
Authors: Reiter Grandi Maria Vitória
Published: April 2024

No Brasil, além das consequências trágicas que a pandemia de COVID-19 trouxe para a área da saúde, surgiram outros problemas graves, como o aumento do desemprego, aumentos sucessivos nos preços de diversos produtos e a diminuição da renda domiciliar per capita. Algumas pesquisas recentes indicam que esses problemas provocaram mudanças no perfil de consumo das famílias, porém são pesquisas bastante específicas e que empregaram de forma bastante restrita técnicas de mineração de dados. Neste sentido, este trabalho teve como objetivo aplicar a técnica de mineração de regras de associação para: a) identificar os padrões de compras em uma rede de supermercados da região oeste do Paraná durante o período anterior e durante a pandemia de COVID-19; e b) comparar os padrões obtidos para os dois períodos, a fim de possibilitar que os especialistas da empresa pudessem analisar se as diferenças foram inesperadas e relevantes sob o ponto de vista da administração das lojas da rede. Como resultados, o algoritmo Apriori foi aplicado utilizando diferentes valores de suporte e confiança para cada um dos municípios analisados a fim de obter as 30 melhores regras de associação em cada um deles. Por meio destes resultados foi possível identificar que durante o período da pandemia houve uma alteração no padrão de compras dos clientes em relação aos anos de 2018 e 2019, o que para os especialistas da rede de supermercados já era esperado. Porém, ainda segundo os especialistas, houve descobertas importantes para a empresa com a realização deste trabalho, como as alterações dos padrões de compras específicas de cada município durante os anos de 2020 e 2021.

Authors: Jiang Yurong , Deng Xinru , Shih Chungkun , Zhao Yunyun , Ren Dong , Zhao Zhipeng
Published: April 2024

Mastotermitidae, the first-diverging extant family of termites, has only one relic extant species; however, this family had greater richness during the Mesozoic and Cenozoic eras. Fossil termites from the Cretaceous provide information on the early evolution of termites and the transition between extinct families. Herein, two new Mastotermitidae species found in upper Cretaceous (Cenomanian) Kachin amber are reported. One is a female imago described as Angustitermes reflexusgen. et sp. nov. and assigned to the subfamily Mastotermitinae. The other is Mastotermes reticulatussp. nov., which is described from an isolated forewing. With the comparison especially of the antenna and venation, these new mastotermitids further increase our knowledge of the diversity and morphology of Mastotermitidae during the Mesozoic.
Modèles et métaphores dans les projets système d’information
Authors: Figueiredo Marie Bia , Morley Chantal
Published: April 2024

En France, J.-L. Le Moigne a apporté une nouvelle perspective à l’ingénierie des systèmes d’information (SI), en promouvant l’analyse et la modélisation des systèmes. L’utilisation de modèles a apporté une contribution majeure à la conception des SI. Les méthodologies systémiques se sont multipliées à partir des années 1980, avant de céder la place aux approches agiles. Plusieurs facteurs ont contribué à repenser le rôle de la modélisation dans la conception des SI : la faible adoption des modèles par les utilisateurs, l’émergence d’une vision du développement des SI comme un processus social et la demande accrue d’innovation. Les approches récentes ont fait une place aux métaphores comme outil d’appréhension de la complexité des SI, à la fois dans les projets et dans la recherche. Nous présentons diverses utilisations d’une approche métaphorique dans la conception de SI. Nous décrivons ensuite comment nous avons utilisé des métaphores du pouvoir pour étudier les pratiques de leadership dans un projet de développement SI mené en mode agile.
Réalisme et engagement dans la recherche en gestion :
Authors: Louart Pierre
Published: April 2024

Cet article s’inspire librement d’écrits de Jean-Louis Le Moigne, en particulier de la manière dont il aborde la réalité managériale, objet de recherche pour les sciences de gestion. Il en a intégré la complexité par des interprétations systémiques. Il a montré qu’on ne pouvait la dissocier des acteurs qui la pensent ou agissent sur elle. On ne la connaît vraiment qu’en interférant avec elle, ce qui engage à la transformer, puisque les sciences de gestion sont aussi des sciences de l’action. Dans le texte qui suit, nous avons insisté sur trois dimensions complémentaires : on n’est réaliste qu’en acceptant la complexité, puisqu’on vit au sein du réel, on y est engagé ; on ne peut se passer d’interagir avec lui pour le comprendre ; ce faisant, parce qu’on en saisit les contradictions ou les imperfections, on est conduit à le faire évoluer, en recherche, l’intelligence est dans l’art des bonnes questions, celles qui vont donner des réponses éclairantes et utiles pour l’action.

Authors: Adamshick Pamela Z. , Payton Colleen
Published: April 2024

Background:

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based protocol for early identification and treatment for substance use. Adolescents are a high-risk group for substance use.

Method:

SBIRT simulation was conducted among nursing students (
n
= 79). Surveys were administered before (pretest), immediately after (posttest 1), and 3 weeks (posttest 2) after simulation. Outcome scores including attitude, role security, therapeutic commitment, knowledge, confidence, competence, readiness, and response to scenarios and cases were compared between traditional undergraduate nursing students who received educational reinforcement before the posttest 2 survey and postbaccalaureate students.

Results:

Mean scores for attitude, role security, knowledge, confidence, competence, readiness, and scenarios or cases improved significantly after the simulation (
p
< .005). Traditional undergraduate and postbaccalaureate students had similar posttest 1 and posttest 2 scores.

Conclusion:

After SBIRT simulation, outcomes improved and were maintained after educational reinforcement, which could increase the success of interventions for substance use among adolescents.

Some new results involving residual Renyi's information measure for $ k $-record values
Authors: Shrahili Mansour
Published: April 2024

This article dealt with further properties of the Renyi entropy and the residual Renyi entropy of $ k $-record values. First, we discussed the Renyi entropy order and its connection with the usual stochastic and dispersive orders. We then addressed the monotonicity properties of the residual Renyi entropy of $ k $-records, focusing on the aging properties of the component lifetimes. We also expressed the residual $ n $th upper $ k $-records in terms of Renyi entropy when the first dataset exceeded a certain threshold, and then studied various properties of the given formula. Finally, we conducted a parametric estimation of the Renyi entropy of the $ n $th upper $ k $-records. The estimation was performed using both real COVID-19 data and simulated data.

Gold nanoparticles (AuNPs) have garnered significant interest in the field of biomaterials and biomedical engineering due to their wide-ranging applications, excellent biocompatibility, low toxicity, and customizable stability. This study focuses on synthesizing AuNPs through an environmentally friendly approach, specifically by utilizing the aqueous leaf extract of Allium tuberosum as both a reducing and capping agent. The synthesized AuNPs were characterized using UV-Vis Spectroscopy, revealing an absorption peak at 548 nm within the surface plasmon resonance (SPR) of AuNPs. Morphological analysis conducted via SEM showed a mixture of rod-shaped and spherical-shaped AuNPs, with dimensions of 41.0 nm (width) and 181.6 nm (length) confirmed through DLS measurements. EDX analysis confirmed the high abundance of gold in the synthesized AuNPs. Furthermore, a zeta potential value of -26.2 mV indicates that the AuNPs have decent stability. Phytochemical analyses and FT-IR results implicated that the Saponin present in the Allium tuberosum leaf extract played a crucial role in reducing metal ions and stabilizing the AuNPs. The potential of Allium tuberosum leaf extract for synthesizing diverse metal nanoparticles highlights its promise for biomaterials and biomedical engineering. The synthesized AuNPs show versatility for applications like targeted drug delivery, non-invasive imaging, and emerging biomedical uses.
A Sleep Apnea Detection Methodology Based on SE-ResNeXt Model Using Single-Lead ECG
Authors: Vu Tran Anh , Phuong Do Thi Thu , Huy Hoang Quang , Kien Nguyen Phan , Huong Pham Thi Viet
Published: April 2024

Sleep apnea (SA) is considered one of the most dangerous sleep disorders. That happens when a person is sleeping, his or her breathing repeatedly stops and starts. In order to develop therapies and management strategies that will be effective in treating SA, it is critical to precisely diagnose sleep apnea episodes. In this study, the single-lead electrocardiogram (ECG), one of the most physiologically pertinent markers for SA, is analyzed to identify the SA issue. In this paper, a novel signal processing method is proposed, in which noise filtering is added and the detection of R peaks is utilized. Particularly, the Teager Energy Operator (TEO) algorithm is applied to detect R peaks and then obtain the RR intervals and amplitudes. Afterward, the SE-ResNeXt 50 deep learning model, which has never been used in SA detection before, is used as a classifier to perform the objective. The proposed model, which is a variation of ResNet 50, has the ability to use global information to highlight helpful information while allowing for feature recalibration. In order to confirm the proposed method, the benchmark dataset PhysioNet ECG Sleep Apnea v1.0.0 is used. Results are better than current research, with 89.21% accuracy, 90.29% sensitivity, and 87.36% specificity. This is also clear evidence that the ECG signals can be taken advantage of to efficiently detect SA.

Conclusions in literature regarding the effect of Autism on the size of different brain structures are contradictory. The aim of this study is to determine the effect of Autism on the volumes of different brain subcortical structures, and the age stage at which those changes occur. 7 main brain structures were segmented and their volumes were obtained. Volumes and the ratio of the volume to total brain volume (SBR) were compared in Autism group to their corresponding values in Control group. Then, each group was divided into 4 subgroups based on age; the comparison was repeated for each subgroup. Independent t-test was used to determine if significant differences existed between compared groups. Significant reductions were observed in the SBR of Autistic Pallidum and Accumbens compared to Control group when considering the full range of ages (5–25 years). However, Amygdala’s volume was significantly smaller in Autism in the 5–8 year subgroup. In addition, the SBR of Putaman, Pallidum, Hippocampus, and Accumbens were reduced in the 18–25 year Autism subgroup. In conclusion, the alteration in the ratio of structure’s volume to total brain volume is a better indicator of Autism diagnosis than change in the absolute volume alone.

The reflected power function distribution (RPFD) has increasing importance in practical life due to its application in diversified fields of life. Organisations often face difficulty monitoring operations to identify and remove errors during production. That is why there is a need to introduce control charts that effectively monitor the processes, mainly when the number of errors follows RPFD and the manufacturing process is in control. The current study suggested memory-based control charts as a solution to the problem. The control charts are based on the estimation methods and play a remarkable role in enhancing the machine process reliability. The parameters of RPFD are evaluated through the percentile estimator (PE) and modified maximum likelihood estimator methods (MMLM). Further, we create memory-based control charts, i.e., hybrid exponentially weighted moving average (HEWMA) and extended exponentially weighted moving average (EEWMA), using the PE and MMLM. The findings reflect that HEWMA control charts based on PE provide a better result in estimating the defects. The implications of the study will be helpful for practitioners and policy makers from reliability engineering, management sciences, and statisticians.

Buffaloes have great potential to be developed as one of the main dairy animals in Sri Lanka because of their higher adaptability to local conditions compared to European dairy cattle breeds. Processing dairy products such as curd, cheese, and yoghurt from buffalo milk has several advantages due to its greater quantities of total solids, solid-nonfat, and protein. However, milk composition and coagulation properties largely depend on the breed. Therefore, this research aimed to investigate the milk composition of three major buffalo breeds in Sri Lanka. The milk of the Lanka buffalo contained 18.1% total solids, 10.7% solid non-fat (SNF), 7.5% fat, 4.9% protein, 4.9% lactose, and 0.9% minerals. The milk of the Murrah crossbreed contained 15.4% total solids, 10.1% SNF, 5.3% fat, 4.2% protein, 5.1% lactose, and 1.1% minerals. The milk of the Nili-Ravi crossbreed contained 16.6% total solids, 10.2% SNF, 6.4% fat, 4.1% protein, 4.9% lactose, and 1.1% minerals. The results indicate that milk composition varies among the breeds in which the milk of the Lanka buffalo has significantly higher amounts of total solids, SNF, and fat. Protein, lactose, and mineral contents do not vary signiticantly.

An evaluation of various botanical insecticides to control Aphis gossypii and its impact on aphid population dynamics on chrysanthemum plants was investigated. In order to control A. gossypii on chrysanthemum, the effectiveness of several botanical insecticides extracted from Melia azedarach, Toona sinensis, and Chrysanthemum cinerariaefolium was investigated in the current study. The research was carried out in the experimental field of the Indonesian Ornamental Crops Research Institute under plastic house conditions. Five concentrations, i.e., 1.5, 2.0, 2.5, 3.0, and 3.5 g/L of three plant extracts, M. azedarach, T. sinensis, and C. cinerariaefolium, were sprayed on chrysanthemum cultivar White Fiji after 28 to 84 days after planting. A. gossypii had a dynamic population that changed according to the plant’s developmental stages. In vegetative growth, the alate adult and nymphal stages were dominant, and the population of nymphs increased along the plant ages. The insect colonized young leaf surfaces in the terminal apices. During the reproductive stages, the population of alate adults diminished, and the distribution of the insect extended to mature, old leaves, flower buds, and bloomed flowers. The application of several botanical insecticides revealed various responses of aphid populations. Among the tested insecticides, C. cinerariaefolium extract at 3.0 and 3.5 g/L demonstrated the highest average percentage efficacy (76 and 72%) and was the most consistent in suppressing the population. The results of this study indicate the potential efficacy of botanical insecticides against A. gossypii suggesting a different approach to efficient and environment-friendly chrysanthemum pest management.
Per una psicoterapia d’ispirazione sociale
Authors: D'Elia Luigi
Published: April 2024

In questo articolo s’intende ri-significare e rinnovare la pratica e la teoria della clinica della psicoterapia in relazione ai vistosi cambiamenti degli scenari sociali e politici degli ultimi decenni della nostra storia. Vengono suggerite nuove modalità di osservazione dei fenomeni patoplastici e si esplorano le relazioni fra macro e micro fenomeni dello psichismo. Si revisionano alcuni assetti interni dello psicoterapeuta alla luce di un rinnovato sguardo sinottico e grandangolare. Si valuta l’impatto alienante degli attuali e specifici determinanti sociali sulla vita quotidiana delle persone e si suggerisce una clinica della resistenza a difesa di dignità, libertà e verità del soggetto contemporaneo.
Resilienza, resistenza o presenza? Commento a ‘Per una psicoterapia d’ispirazione sociale’ di Luigi D’Elia
Authors: Vincenti Enrico
Published: April 2024

D’Elia in questo articolo fa una proposta relativa alla necessità di una rivisitazione e una più precisa definizione di una psicoterapia sociale che trovo interessante, così come l’invito agli psicoterapeuti di posizionarsi rispetto all’attualità del momento storico e delle trasformazioni in atto. Attualità e trasformazioni che incidono sulle manifestazioni del disagio e della sofferenza umana. [...]
Commento all’articolo ‘Vero uomo o uomo vero? Quale contributo serve oggi per la prevenzione primaria della violenza di genere e per sostenere la salute mentale di bambini, adolescenti e uomini’

Scrivo questo commento all’interessante articolo di Alberto Pellai in un giorno di fine novembre, vicino alla data del 25, giornata internazionale per l’eliminazione della violenza contro le donne. A questo appuntamento ci stiamo avvicinando come collettività in maniera dolorosa, con la consapevolezza che le azioni finora proposte sono del tutto insufficienti a dare una risposta ad un problema che continua ad aumentare nelle sue dimensioni e che ci riguarda in maniera sempre più evidente. I fatti di cronaca in cui troppo spesso inciampiamo ce lo ricordano in maniera cruda e ci obbligano a fare un pensiero su quanto vediamo accadere. [...]
Commento al film: Border – Perdutamente tua (Now, Voyager)
Authors: Mistrali Maurizio
Published: April 2024

Un film certamente interessante, dai tanti temi sviluppati in una sola trama che si intrecciano mostrando, tra l’altro in presa diretta, e sia pure marginalmente, ma con singolare acutezza, lo stato dell’opera della psicoterapia in quegli anni ed in quel paese. Nell’intreccio, nell’insieme di temi differenti, ampi e interessanti, vengono trattate tematiche non in modo diretto, ma chiaramente interpretabili nella sceneggiatura, che vanno dall’attaccamento, all’individuazione, perfino all’abuso affettivo, e la desatellizzazione (dipendenza, contro dipendenza, autonomia, interdipendenza).

Spinocerebellar ataxias (SCAs) represent a diverse group of hereditary and progressive neurological disorders characterized by their onset in adulthood and commonly exhibit autosomal dominant inheritance. These disorders typically involve multiple brain regions, including the cerebellum, spinal cord, basal ganglia, brainstem, and cortical areas, leading to varied and heterogeneous clinical presentations. In particular, SCA 15 is recognized as an adult-onset, slowly progressive cerebellar syndrome, often accompanied by various other neurological manifestations. In this report, we present a novel clinical phenotype of parkinsonism–dystonia syndrome co-occurring with cerebellar features in a genetically confirmed case of SCA 15.
