Authors: Riveros Andrés , Inzunza Oscar , Burdiles Alvaro , Farfán Emilio
Published: March 2023

Although muscle variations in the forearm have been widely reported, the presence of supernumerary muscles in this compartment may be associated with compressive disorders of the nerves of the upper limb. The purpose of this study was to report the finding of a polygastric flexor muscle of the index finger (PFID), a supernumerary muscle associated with the anterior compartment of the forearm, the morphology and pathway of which are closely related to the median nerve. The PFID was found in a routine dissection of an upper right limb. Following a dissection methodology by planes, a narrow, polygastric muscle was identified, formed sequentially and interspersed by four tendons and three muscle bellies, that extended between the common flexor muscle mass of the anterior compartment of the forearm and the index finger. The sixth part of the PFID was partially in the carpal tunnel and established close relation with the median nerve, which was displaced superficially. Knowledge of this and other muscle variations that appear in the forearm and carpal tunnel are relevant when performing a differential diagnosis of carpal tunnel syndrome or in planning surgery on this canal.

Authors: Priya Ananya , Kant Narayan Ravi , Kumar Ghosh Sanjib
Published: March 2023

The foot arches in humans are the complex musculo-skeletal-ligamentous structure that helps in shock absorption because of the elasticity and provides stability while transmitting the muscle force for walking. Primarily we observed the prevalence of flatfoot among adolescents going to college. Thereafter we determined the correlation of flatfoot with the body mass index and gender of the adolescents being studied. Footprint analysis of undergraduate students was obtained based on Harris – the Beath mat principle. Clarke’s angle, Chippaux-Smirak index, and Staheli arch index were observed in the footprints. Subsequently, the correlation between the flatfoot, body mass index, and gender of the participants was assessed. The prevalence of flatfoot in college-going adolescents was 18.28% by footprint analysis, presenting a female predilection (20% of the footprint analysis) for the condition. The most valid and reliable plantar arch index for diagnosing flatfoot was the Staheli arch index, followed by the Chippaux-Smirak index having a moderate to strong correlation (R = 0.7, 0.95; p < 0.05). Only 1.1% of females and up to 2.2% of males were observed to have flatfoot and were obese. Eighteen out of a hundred (approximately one–fifth) adolescents in the studied group had flatfoot. The gender predilection for females was observed. Contradictory to the findings of the previous study, obesity was not observed as a foot arch-altering factor in adolescents.

Authors: Bazsik István
Published: March 2023

Az élelmiszeriparban egyre nagyobb jelentőséggel bír a folyamatos ellátás, a megbízható minőség, a partnerek megbízhatósága, illetve a tervezhető, folyamatos termelés. Ezen igények kielégítésére alkalmas specifikus eszköz a vertikális integráció, amely az adott ellátási lánc termelési biztonságát és minőségi színvonalát úgy éri el, hogy a rendszerben az integrátor magas kontrollintenzitás mellett direkt módon képes beavatkozni az elvárt eredmények elérése érdekében. Magyarország és Kelet-Közép-Európa legnagyobb tésztagyártója, a Gyermelyi Holding Zrt. által összefogott cégcsoport olyan ellátási láncot épített fel, amely teljesen zárt vertikális integrációt valósított meg. Az élelmiszer-gazdaságban az ellátási láncok mentén a résztvevők között kialakult egyfajta erőviszony, amely a beszállító termelők erős kiszolgáltatottságát eredményezi, és feszültséggel terheli meg az ellátási láncokat. Erre a problémára is adekvát választ nyújthat egy minden fél számára előnyös és elfogadott vertikális integráció. A vállalatcsoporttól a szövetkezeti múltjából adódóan soha nem állt távol az integráció szellemisége, ennek megfelelően a technológiai és kapacitásfejlesztések későbbi kihasználtságának érdekében mindig is igyekeztek integráció útján megteremteni a termeléshez szükséges alapanyag ellátási és minőségi biztonságát. Mára hazánkban egyedülálló, teljesen zárt vertikális integrációt valósított meg a cégcsoport, amely számos olyan elemet épített be az integráció rendszerébe, amely a méltán híres nagy olasz tésztagyártók sikereit is megalapozzák. A Gyermelyi vertikális integrációval ad és adott válaszokat a piacot terhelő kérdésekre – például: alapanyaghiány, logisztikai zavarok, kiszámíthatatlan áringadozások –, amelynek eredményeként mind a beszállítók, mind saját maga sikeres és eredményes lehet, ezzel pedig hosszú távon fenntartható ellátásilánc-struktúrát tarthat fenn. Jelen tanulmány elsődleges célja a Gyermelyi cégcsoport térségünkben egyedi vertikális integrációját mint jó gyakorlatot átfogóan bemutatni.

Published: March 2023

Aiming at the problems that traditional K-means text clustering cannot automatically determine the number of clusters and is sensitive to initial cluster centers, this paper proposes a Canopy-MMD text clustering algorithm based on simulated annealing and silhouette coefficient optimization. The algorithm uses the simulated annealing algorithm combined with the silhouette coefficient to optimize the Canopy algorithm to find the optimal number of clusters, and uses the optimal number of clusters to determine the scale coefficient in the MMD algorithm, and finally achieves a better text clustering effect. The Sohu News dataset of Sogou Lab is experimentally analyzed and compared with the clustering results obtained by traditional K-means and algorithms in the literature. The experimental results show that the clustering performance of the algorithm is better than the traditional K-means algorithm and the algorithm in the literature, and the accuracy, precision, recall and F value are improved by 8.02%, 8.91%, 8.02%, 9.51% compared with the traditional K-means algorithm, which can be widely used in fields such as text mining, knowledge graph and natural language processing.

 
Malware Family Classification Based on Vision Transformer
Authors: Jing Li Jing Li , Jing Li Xueping Luo
Published: March 2023

Cybersecurity worries intensify as Big Data, the Internet of Things, and 5G technologies develop. Based on code reuse technologies, malware creators are producing new malware quickly, and new malware is continually endangering the effectiveness of existing detection methods. We propose a vision transformer-based approach for malware picture identification because, in contrast to CNN, Transformer’s self-attentive process is not constrained by local interactions and can simultaneously compute long-range mine relationships. We use ViT-B/16 weights pre-trained on the ImageNet21k dataset to improve model generalization capability and fine-tune them for the malware image classification task. This work demonstrates that (i) a pure attention mechanism applies to malware recognition, and (ii) the Transformer can be used instead of traditional CNN for malware image recognition. We train and assess our models using the MalImg dataset and the BIG2015 dataset in this paper. Our experimental evaluation found that the recognition accuracy of transfer learning-based ViT for MalImg samples and BIG2015 samples is 99.14% and 98.22%, respectively. This study shows that training ViT models using transfer learning can perform better than CNN in malware family classification.

Body Correlation Network for Person Re-Identifications
Authors: Bailiang Huang Bailiang Huang , Bailiang Huang Yan Piao , Yan Piao Yanfeng Tang , Yanfeng Tang Baolin Tan
Published: March 2023

Visual information accounts for approximately 80 to 85 percent of the information available daily in modern cities. As such, person re-identification, an instance-level image retrieval task, has become an important research topic in computer vision, machine learning, and other fields in recent years. Traditional person re-identification methods based on convolutional neural networks only extract the global feature information of people. Thus, when external factors such as changes in occlusion and illumination disturb people, the recognition performance of these methods substantially decreases. We therefore develop body correlation network (BC-Net), which takes full advantage of images of body parts and the correlations between them. Specifically, BC-Net uses body part feature information and correlation feature information as nodes and edges, respectively, and then uses graph convolutions to learn the overall topology of people. To improve use of crucial feature information, we also design a unique method of propagation between nodes and edges. We conduct extensive comparative experiments on the Market-1501 and DukeMTMC-reID datasets, and the results demonstrate that BC-Net outperforms other state-of-the-art techniques.

FILLING THE LEGAL GAP IN THE BANKING AREA IN VIETNAM BEFORE INDUSTRY 4.0 PRESSURE
Authors: Giang Thu Pham Thi
Published: March 2023

Since 2016, with the appearance of products of industry 4.0 such as block chain, and products of the block chain associated with banking business area, has created many legal issues that need to be resolved.

Block chain eliminates the third parties/intermediaries in transactions. Therefore, how should the role of financial intermediaries be redefined for the present and the future? What legal risks can happen to Vietnamese investors in the market? There is no clear explanation/statement to answer those questions.

What is the legal definition of crypto currency? What role does it play in financial transactions such as investment? Can we use crypto currency as a payment method? These issues have not been resolved in Vietnam either in theory or by noting in a legal document.

As industry 4.0 is based on a big data system, the current managements, administrations, and identifications that credit organizations are implementing have become obsolete and need an overhaul. Current Vietnamese law has not been able to solve this issue.

The above loopholes need to be reviewed and identified a solution. Also, it is necessary to study and understand other countries’ law adjustments that may be applied and considered to adjust Vietnamese legal system. This article is intended to solve these problems as below.
EXPLORING BEHAVIORAL ASPECTS OF MARKET EFFICIENCY AND ANOMALIES
Authors: Wafula Dr. Chesoli, Joshua
Published: March 2023

Market efficiency hypothesis suggests that markets are rational and their prices fully reflect all available information. Due to the timely actions of investors prices of stocks quickly adjust to the new information, and reflect all the available information. So no investor can beat the market by generating abnormal returns. But it is found in many stock exchanges of the world that these markets are not following the rules of EMH. The functioning of these stock markets deviate from the rules of EMH. These deviations are called anomalies. Anomalies could occur once and disappear, or could occur repeatedly. This literature survey is of its own type that discusses the occurrence of different type of calendar anomalies, technical anomalies and fundamental anomalies with their evidences in different stock markets around the world. The paper also discusses the opinion of different researchers about the possible causes of anomalies, how anomalies should be dealt, and what ere the behavioural aspects of anomalies. This issue is still a grey area for research.

Abdomen agudo post-quirúrgico es una entidad plurisintomática cuyas causas principales radican en complicaciones que pueden presentarse en una intervención quirúrgica realizada. En el paciente post- quirúrgico, la peritonitis secundaria a una complicación ocupa del 20% al 45% de las estadísticas internacionales, dentro de éstas el 70% puede desarrollar sepsis, que si no es controlada puede originar un síndrome de disfunción orgánica múltiple con elevada mortalidad; a nivel nacional y local las complicaciones oscilan entre el 10% al 20% de las estadísticas realizadas en las unidades hospitalarias.
Evaluar el abdomen agudo postquirúrgico no es tarea fácil ya que el dolor postoperatorio, el íleo adinámico normal de un paciente intervenido quirúrgicamente puede enmascarar el cuadro clínico y más aún si el paciente está con ventilación asistida y hemodinámicamente inestable.
Esta entidad clínico-quirúrgica en la actualidad se presenta con frecuencia, de ahí que es necesario que el profesional de salud esté pendiente de la evolución de su paciente para identificar y diagnosticar precozmente estas complicaciones que van a originar un abdomen agudo postquirúrgico, condición indispensable para garantizar incluso hasta la vida misma del enfermo.

Antecedentes: El volver a realizar una operación de emergencia después de un tiempo quirúrgico es algo que no solo demuestra un tipo de fracaso de la primera cirugía sino da una alta ansiedad en pacientes que son reintervenidos (Dillstro, Bjersa, & My , 2016). El porqué de estas reintervenciones son vistas debido a múltiples factores que se presentan durante y después de las cirugías laparoscópicas realizadas (Tae Kwan , y otros, 2019). Su identificación temprana es imperativamente necesario ya que así se prevendrían múltiples complicaciones, altos costos hospitalarios y posible aumento de muertes en el quirófano (Xiao, Wang, Quan, & Ouyang, 2018).
Objetivo: Identificar los factores de riesgo más significativos que preceden en las reintervenciones quirúrgicas en cirugía abdominal.
Materiales y métodos: Se recolectaron datos estadísticos de los pacientes del Hospital Abel Gilbert Pontón. Se utilizó el programa de Excel para llevar a cabo las estadísticas y sacar “P” más “OR” y corroborar significancia estadística entre factores de riesgos investigados.
Resultados: Se tomaron dos grupos con diferentes poblaciones entre sí (Grupo A: 860 y Grupo B: 109) al cual se subdividieron en femenino y masculino (Grupo A: masculino:501; femenino:359; Grupo B: masculino:61; femenino:48). Se evidenció que el género masculino tuvo mayor predominio de reintervenciones quirúrgicas abdominales de emergencia en un 58,3% y 56,0% respectivamente.
Las principales complicaciones postquirúrgicas que existieron en los pacientes reintevernidos fueron infecciones de sitio quirúrgico (46.8%) colección intraabdominal (26.6%) y shock séptico (24.8%). También hubo cifras estadísticas significativas en comorbilidades (glicemia e hipertensión arterial), tiempo quirúrgico y valores en la química sanguínea.
Conclusiones: se necesitan más estudios en el Ecuador que revelen más clases de riesgos que presentan los pacientes reintervenidos de manera súbita con el objetivo de que se conozcan y por lo tanto disminuir su incidencia.

La infección del sitio quirúrgico es un problema devastador para el paciente, así como para la unidad hospitalaria donde se encuentra, con el aumento de la morbi-mortalidad. Unos de los métodos actuales en el tratamiento de las heridas infectadas (I.S.Q) está el sistema de cierre al vacío o V.A.C.
Se ha demostrado que, con el sistema de succión al vacío, las cicatrizaciones de las heridas se aceleran con esto la estancia hospitalaria disminuye, así como también el gasto de insumos de curación (antisépticos, hidrocoloides, alginatos, crema antibiótica, etc.) y de antibióticos sistémicos utilizados en el proceso de curación. En el estudio realizado de 92 paciente que se utilizó el sistema al vacío o V.A.C el 91% de los pacientes mostraron mejoría o curación con la utilización de este sistema.

Las escaras, ulcera por decúbito o ulcera por presión, son lesiones de la piel, que puede llegar a celular subcutáneo o musculo provocada por presión, fricción, rozamiento prolongado, por lo general sobre una prominencia ósea. Los sitios más frecuentes de aparición son las superficies que recubren partes óseas (prominencia ósea) como el sacro, trocánteres, tobillo, talones, etc. Su incidencia varía entre un 7,5% en las unidades hospitalaria y u 8,5% en los pacientes atendidos en el primer nivel de atención, pero prevenible en un 90%. La mayoría de los pacientes que presentan este problema son ancianos con o sin problemas neurológicos. Se realizó un estudio prospectivo de casos, recogiendo la información de la base de datos del departamento de enfermería del cuarto piso, área de curaciones avanzada del Hospital Abel Gilbert Pontón. Respecto a la ulcera por presión o ulceras por decúbitos, encontramos que la más frecuente fue la de localización sacra en un 63% (422 pacientes de un total de 666 pacientes) seguidas de la ulceras de talón en un 18%; siendo el estadio II el de mayor prevalencia.
