Published: November 2024

Pregnancy in rudimentary horn is a rare occurrence with incidence of less than 1 in 150,000. Pregnant rudimentary horn can present with wide range of symptoms that may be similar to ectopic pregnancy or may remain silent with features of normal pregnancy. Management is typically resection of the rudimentary horn by either laparotomy or laparoscopy. This case has been reported for its rarity and dilemma in diagnosis which is a case of a 21 years old, married since 1 year primigravida nullipara presented with 3 and half month amenorrhea with acute abdomen since 2 days. Her vitals were stable with severe anaemia (Hb 5 gm%). Her obstetric USG showed features of 14 weeks foetus in probably rudimentary horn on left side. Right sided horn showed normal endometrial thickness. Patient’s emergency laparotomy was done with excision of rudimentary horn containing the pregnancy. The wall of rudimentary horn showed rupture with hemoperitoneum 200 ml. To conclude, uterine abnormalities are rarely encountered in pregnancy. Attempts should be made for early diagnosis to avoid maternal mortality. Ultrasound in the first trimester may provide a means of an early diagnosis. It requires proper history, high level of suspicion, routine early pregnancy scan and documentation of operative findings. Rudimentary horn pregnancy should always be kept as differential diagnosis in early second trimester pregnancy with acute abdomen.
The Lateral Surface Phonon Modes in Bi-layer Dielectrics with Different Values of Permittivity
Authors: Gunawan Vincensius 
Published: November 2024

Surface phonon polaritons were electromagnetic waves that propagated at the surface of dielectrics. These polaritons had many attentions since the frequency can reach in the order of terahertz. Hence, it can be employ in terahertz technology. One of the general method to study polaritons was by solving Maxwell's equations. The results were dispersion relation which showed the characteristic of the polaritons. In this study, we analyze polaritons of a bilayer dielectric which was comprised of two dielectrics which had different permittivities. We set the thickness of each dielectric was smaller than the wavelength so that we could use effective medium method. In this approximation, we can treat a multilayer system as a single effective medium medium. We also assumed that the surface modes propagated across the thickness of each dielectric. It was found that when the resonant frequency of the two dielectrics were considerably wide, then we had two branches of surface polaritons. In this result, each branch represented each dielectric. The interesting results appeared when there was intersection of the the frequencies near resonant frequency of the dielectrics. In this condition, we found only one branch of surface modes.
Economía solidaria con enfoque de género en Ecuador
Authors: Lanas Medina Elisa 
Published: November 2024

Pese a la cercanía a nivel teórico en que se encuentran la economía feminista y la economía solidaria, en la práctica, la participación de las mujeres en la ES no ha contado en Ecuador con adecuadas garantías normativas ni institucionales. Es reciente la preocupación de las instituciones públicas por proveer información de la participación en la ES de las personas desagregada por género, que permite visualizar las menores oportunidades que las mujeres tienen frente a los hombres de desarrollarse integralmente en esta economía. Más grave aún es la total ausencia de información y por tanto valoración del aporte personal que las mujeres realizan respecto al cuidado humano y atención de las tareas domésticas y comunitarias que no son para la economía productiva. Es preciso y urgente implementar acciones que permitan contabilizar, valorar y retribuir económica y socialmente esas actividades. Además, hay que impulsar un verdadero cambio de roles en las actividades que hombres y mujeres desempeñan en la ES.

Authors: León Ricardo , Oñate-Paredes Carlos Andrés 
Published: November 2024

El buen gobierno cooperativo se define como aquella instancia donde las organizaciones desarrollan su objeto social dentro de una estructura social democrática, y, donde los socios cumplen funciones asignadas tendientes a satisfacer las necesidades y alcanzar los fines institucionales. El sector cooperativo de ahorro y crédito del Ecuador ha experimentado una significativa disminución de sus miembros a partir del control que ejecuta la Superintendencia de Economía Popular y Solidaria, esto por varios problemas relacionados con la forma de gobernar dichas instituciones, entre otros: incumplimiento de las normas, decisión voluntaria de los líderes y crisis financieras. En este contexto, la presente investigación plantea y analiza los requisitos para la implementación del buen gobierno en cooperativas de ahorro y crédito (COAC), partiendo del enfoque institucional hasta el enfoque asociativo, sobre la base de un detallado análisis bibliográfico y sustentado en la aplicación de una ficha de entrevista para cuatro representantes legales de COAC del segmento tres de la provincia de Tungurahua. Los resultados del estudio indican opciones de mejora de los principios de cooperación entre COAC, interés por la comunidad, gestión democrática y educación, formación e información, siendo importante la necesidad de ajustes en estas áreas para cumplir con la función social de dichas organizaciones.

Les implications épistémiques de la "vagueness" du hasard et de la "non-vagueness" de l'aléatoire
Authors: Escudero Mathilde 
Published: November 2024

Dans cet article je propose la double-thèse :

du caractère « vague » (tel que défini dans la littérature logico-sémantique contemporaine) de la notion de hasard (chance) par opposition au caractère « non-vague » de celle d’aléatoire (randomness) ;
du lien entre la vagueness et le pouvoir explicatif du hasard et la non-vagueness et la capacité descriptive de l’aléatoire, lequel plaide en faveur d’usages distincts de ces deux notions.

Pour défendre la première thèse, j’ai recours aux définitions des notions de hasard et d’aléatoire et à un exemple de l’histoire des sciences (la théorie du chaos). Pour appuyer la seconde, je fais appel à des exemples scientifiques : la variation dans la théorie darwinienne de l’évolution, la mutation génétique dans la synthèse moderne et la dérive génétique dans la théorie neutraliste de l’évolution.

The latest COVID-19 pandemic has taught the importance of nutrition and immunity to prevent diseases, in which case the fatality rate exceeded 2.58%. Immunity is believed to be one of the critical efforts to prevent the spread of COVID-19. This is, for sure, inseparable from nutritional intake, exercise, and environmental factors. However, that needed to be better understood by many people. This study aims to assess the effectiveness of online-based nutrition education in increasing knowledge and self-efficacy to maintain a balanced nutritional intake and implement hygiene. Online-based nutrition education was done using video conference by Zoom conference and text-based education methods using Telegram. Each session is held for approximately two hours. Samples were all collected voluntarily, comprising an adult population aged 19 – 5 . Knowledge and self-efficacy were measured using a structured questionnaire. In total, 217 samples were recruited. 92.2% of participants were female, the average age was 29 ± 10.04, 34.1% worked as civil servants, and the majority, 52.1%, came from East Java. Education with the digital learning method succeeded in increasing nutritional knowledge from a score of 55.9 to 91.8 (p<0.000) and significantly increasing self-efficacy of consuming balanced-nutritious food and self-efficacy of a clean and healthy lifestyle (p<0.000). In conclusion, online-based nutrition education proved effective in increasing knowledge and self-efficacy. Hence, program duplication with a broader range of subjects can be done nationally.

Published: November 2024

Sampah menjadi permasalahan yang pelik di daerah perkotaan. Pertumbuhan volume sampah tidak diikuti dengan kecepatan yang sama pada penambahan tempat penampungan akhir. Salah satu upaya mengatasinya adalah dengan menekan jumlah sampah akhir melalui gerakan bank sampah. Namun ternyata selain masalah kebiasaan, salah satu kendala yang dihadapi adalah terbatasnya area rumah untuk dapat memilah dan menyimpan sampah sebelum disetor ke bank sampah, yang mana selama bank sampah tidak dapat buka setiap saat. Bertempat di Bank Sampah Permata Cimanggis, penulis berusaha menawarkan program pengadaan station sederhana untuk menampung sampah di level rumah tangga. Dengan menerapkan prinsip partisipasi, tawaran disampaikan dalam forum diskusi dengan masyarakat. Dari proses diskusi dengan pengelola bank sampah, beberapa anggota bank sampah dan pengurus RW, akhirnya disepakati sebuah sistem baru di bank sampah, yaitu sistem setor mandiri. Dalam sistem ini RW menyediakan tempat untuk menyimpan sampah. Pengelola menyediakan peralatan yang memungkinkan nasabah untuk dapat melakukan setor sampah secara mandiri tanpa harus menunggu bank sampah buka. Dengan cara demikian diharapkan simpanan sampah tidak perlu menumpuk di rumah. Masalah keterbatasan area di rumah, menjadi terpecahkan.

Authors: Ekawati Yurida 
Published: November 2024

Departemen fiber merupakan salah satu departemen yang ada di PT. XYZ yang memproduksi panel dan peralatan bus. Berdasarkan data produksi fiber selama dua bulan terdapat 92 cacat dari 547 produk yang dihasilkan. Jumlah cacat tersebut dianggap cukup besar, oleh karena itu perlu dilakukan analisis untuk mengetahui penyebab cacat tersebut dan melakukan perbaikan untuk mengatasinya. Tujuan penelitian ini adalah menganalisis penyebab cacat produk melalui analisis penyebab dan dampak kegagalan pada proses produksi serta memprioritaskan perbaikan menggunakan metode Failure Mode and Effect Analysis (FMEA) pada siklus DMAI (Define, Measure, Analyze, Improve) Six Sigma. Terdapat tujuh jenis cacat pada produk dalam proses produksi yaitu tebal fiber tidak sesuai standar, tekstur fiber tidak rata, terdapat bercak putih pada fiber, fiber tidak kering secara sempurna, fiber reject (cair/terbakar), hasil dempul yang tidak sempurna, dan hasil cat yang tidak sesuai standar. Rekomendasi perbaikan dilakukan untuk meningkatkan kualitas berdasarkan nilai RPN sedang sampai tinggi dari FMEA. Beberapa usulan perbaikan yang diterapkan adalah pencegahan kegagalan tekstur permukaan fiber, pencegahan kegagalan akibat kesalahan campuran katalis dan pencegahan kegagalan hasil dempul. Penerapan usulan perbaikan tersebut dapat menurunkan nilai DPMO dari 24.027 menjadi 6.543 dan meningkatkan level sigma dari 3,48 menjadi 3,98.

To Assess the Role of Biomarkers in Evaluation of Anastomotic Leak Following Planned Colorectal Surgeries To Facilitate Early Removal Of Drain (Controlled Clinical Trial)
Authors: Sankaran Arrjun , Agrawal Sushrut , Patni Sanjeev , Saini Shashikant 
Published: November 2024

Abstract

PURPOSE
There is a need of parameters to predict Anatomotic leak (AL), allay apprehension for early drain removal and facilitate ERAS in patients with colorectal anastomosis. The purpose of this study was to assess the efficacy of biomarkers in the evaluation of anastomotic leak after colorectal surgery, and facilitate early removal of abdominal drain.
METHODS
It was a Randomised Case Control study with duration of 2 years (April 2021 to March 2023). Patients were followed up for 30 days post-surgery which was conducted in a Tertiary care cancer centre in India. It included a total of 90 patients with biopsy proven Colorectal Carcinoma undergoing elective surgery. They were subjected to 1:1 randomization to case and control group with each arm having 45 patients. Assessment of serum C-Reactive protein, serum Procalcitonin and drain fluid Carcinoembryonic antigen (CEA) level done on postoperative day (POD) 3 and POD 5. USG Whole abdomen screening was done on POD 3 and 5 if all were normal. Drain removed early if all parameters were normal in Cases and as per institutional protocol in controls.
RESULTS
Mean age of patients was 54.1 years. Two groups were similar with respect to histologic subtypes, rate of lymphovascular/ perineural invasion, rates of lymph-node involvement, tumor grade. Most common pT staging was noted to be pT3 and pN staging was pN0. Both POD 3 and 5 measurements of CEA, POD 5 measurements of CRP and PCT were found to be significantly elevated in patients who manifested an AL.
CONCLUSIONS AND RELEVANCE
The primary outcome was the ability of the said biomarkers in early prediction of leak leading to early drain removal in patients with a lower chance of AL.
Drain tube CEA measurements on POD 3 and 5 were noted to be most accurate in prediction of early anastomotic leak as compared to Serum CRP and PCT and led to earlier drain removal in those patients in whom anastomotic leak had been ruled out.

Abstract

Objectives
The current study aimed to investigate the structural and functional connectivity of the subregions of the amygdala in children with Attention Deficit/Hyperactivity Disorder (ADHD) only or comorbid with Oppositional Defiant Disorder (ODD).
Methods
A total of 354 children with ADHD-only, 161 children with ADHD and ODD (ADHD + ODD) and 100 healthy controls were enrolled. Several rating scales were filled out by caregivers. Analysis of covariance (ANCOVA) was performed to test group-wise differences in these behavioral measures. A subsample comprising 209 participants went through a resting-state functional MRI scan and a Diffusion Tensor Imaging (DTI) scan. Functional connectivity and structural connectivity were calculated using bilateral subregions of the Amygdala as seeds. Between-group voxel-wise comparisons were conducted.
Results
The ADHD + ODD group had more anxious/depressed moods, more delinquent and aggressive behaviors, more emotional control problems, and more inhibition deficits than the ADHD-only group (all PBonferroni−corrected < 0.05). Compared with the control and ADHD + ODD groups, the ADHD-only group displayed increased FC strength between the amygdala subregions and the left caudate, left putamen, and frontal cortex. Regarding structural connectivity (SC), the ADHD-only group demonstrated higher streamline density in the left internal capsule, corpus callosum, and the right superior corona radiata. The altered SC was associated with emotional problems in children with ADHD, while the altered FC was associated with other ADHD-related clinical features.
Conclusions
Altered structural and functional connectivity of the subregions of the amygdala in children with ADHD compared with their healthy counterparts were respectively associated with ADHD-related behavioral and emotional problems.

Abstract

Purpose
It may be difficult to achieve satisfactory and maintenance of good reduction in partially or completely displaced intra-articular fracture of the type C distal radius fractures. The purpose of this study is to retrospect and summarize a method using multi-direction temporary Kapandji pinning technique and volar locking plate fixation for type C of distal radius fractures.
Method
15 patients with type C of distal radius fractures who underwent an operation between January 2024 and April 2024 in this study. The operation involved multi-direction temporary Kapandji pinning technique followed by stable osteosynthesis using a locked plate system. We present a multi-direction temporary Kapandji pinning technique to fixation followed by rigid fixation with distal radial volar locking compression plate. After 2–3 months of follow-up, evaluated the treatment effect of wrist function by the modified Mayo wrist scoring system.
Results
According to the modified Mayo wrist scoring (MMWS) system, the functional assessment revealed good to excellent results in most cases.
Conclusion
This reduction technique was not only easy to perform but also reproducible. Satisfactory reduction alignment was achieved with minimal leverage force. Rigid and stable fixation is achieved with the volar locked plate system.
Does the handsome man trap work? A study on the impact of male anchors’ reverse gender traits on female consumers’ purchasing intention
Authors: Shen Xiangdong , Jiao Chunlan , Gu Yixian , Zhang Tingxuan 
Published: November 2024

Abstract

This study aims to explore how the reverse gender characteristics of male anchors in the live streaming consumption field attract female consumers and influence their purchasing behavior. Based on the interpersonal attraction theory and the PAD three-dimensional emotion model, the male anchor's physical attractiveness, verbal attractiveness, femininity and masculinity are taken as independent variables, female consumers’ sense of pleasure, arousal and dominance are taken as mediating variables, social presence is taken as a moderating variable, and female consumers' purchase intention is taken as the dependent variable, thus proposing research hypotheses and models. The study used structural equation modeling (SEM) to verify the hypotheses using empirical data from 443 female consumers. Research results show that the reverse gender characteristics of male anchors not only have a significant positive impact directly on the PAD three-dimensional emotion model, but also affect female consumers' purchase intention through the mediating effect of the PAD model. Social presence plays a positive moderating role in the relationship between female consumers' sense of arousal and purchase intention. The study expands the application of gender reverse marketing related theories in live e-commerce scenarios and provides targeted reference suggestions for e-commerce anchors, MCN agencies and merchants.
Optimization of cathode flow field of tri-snake PEMFC based on enhanced mass transfer and water management
Authors: Li Hongen , Ren Hongjuan , Li Cong , Yan Yecui 
Published: November 2024

Abstract

The flow field structure of the cathode of a proton exchange membrane fuel cell (PEMFC) is an important factor in determining its performance. In order to improve the performance of PEMFC from the flow field structure, a trapezoidal baffle is arranged in the channel, and the influence law of the structural height and arrangement of the trapezoidal baffle on the performance of PEMFC is numerically investigated. The results show that the addition of trapezoidal baffles in the cathode flow channel enhances the mass transfer effect of the reaction gas from the inlet flow channel to the GDL compared with the conventional channel, and the limiting current density is increased by 14.49% compared with that of the conventional tri-snake flow channel without baffles. The maximum power density can be obtained at a baffle height of 0.7 mm with better water management effect, and the maximum power density can be increased by 34.85% at the same operating current compared with the conventional flow channel. When the baffle arrangement density is 75%, its enhanced mass transfer and water management effect is basically the same as when the baffle arrangement density is 100%.
Effects of tourism on well-being from the perspective of key actors: a scoping review

Published: November 2024

Abstract

Tourism generates both positive and negative impacts, affecting the well-being of various stakeholders such as tourists, residents, workers and governments. The effects include economic growth, infrastructure and employment, but also environmental and social problems. Related literature reviews are scarce and have concentrated on separately identifying the relationship between tourism and the well-being of tourists or residents. This study seeks to examine the link between tourism activities, their effects and the well-being of the different actors involved in the production or consumption of tourism goods and services. Through an inductive methodological approach, a scoping review was conducted based on 89 studies published between 2014 and 2024. Articles were selected that assessed well-being from quantitative, qualitative and mixed perspectives, focusing on key actors in the tourism system. Significant well-being effects were identified for tourists, who experience temporary improvements in life satisfaction due to tourism experiences. Residents show both positive and negative impacts on their quality of life, while workers and governments have been less studied. Tourism well-being should be understood as a multidimensional phenomenon that affects various stakeholders in an interrelated manner. It is recommended to design public policies that integrate the interests of all key stakeholders to maximize the benefits of tourism and minimize its negative externalities.
