The Impact of the Complexity of Information Systems on User Performance Case of Moroccan Companies
Authors: Badda Atmane , Fath-Allah Rahmouni Ahmed 
Published: March 2023

The literature review highlights that the complexity of information systems increases with the increase in size and with the decrease in the percentage of family actions within the company, as well as having a highly trained leader. An analysis of previous works shows that several researchers have used the criterion of the degree of complexity to characterize information systems.
The first objective of our research is to assess the influence of the degree of complexity of information systems on the frequency of their use. We will then examine the impact of this frequency on the overall work performance of information system users. However, we conducted a questionnaire survey and we were able to analyze just the responses of 49 companies.
Given that the objective of our research is to examine the influence of the degree of complexity of information systems on the frequency of use and to assess the impact of this frequency on the performance of users, and in order to confirm or refute our research hypotheses, we conducted a data analysis using IBM SPSS Statistics 25.0 software, which allows us to perform the chi-square independence test to determine the existence of a relationship between the qualitative variables.
Our results prove the significant impact of the degree of complexity of information systems - defined by the quality of its functionalities, its outputs and its flexibility - on the frequency of use. They also highlight the influence of this frequency on user performance defined by speed, productivity and response to work needs.
Our study has limitations that open research perspectives in the future. Taking into account the national aspect of our study, it would be interesting to understand our results in different cultural areas with more qualitative devices and with a larger sample.
Aportes al estudio de la alimentación prehispánica y los cultivos andinos en el sector centro-sur de la Quebrada de Humahuaca (Argentina)
Authors: Scaro Agustina , Musaubach Maria Gabriela 
Published: March 2023

La alimentación es una actividad estructurante y organizadora de la vida social, en la cual dar y recibir alimentos se convierte en el símbolo de la relación dentro del grupo. En esta oportunidad, se analiza el procesamiento culinario y su consumo en el sector centro-sur de la Quebrada de Humahuaca (norte de Argentina) bajo el dominio incaico (ca. 1430/80-1536 d. C.), en el que se busca identificar los cultivos andinos procesados y consumidos a partir del estudio arqueológico de los microrrestos vegetales. Se realizaron estudios arqueobotánicos de fitolitos y granos de almidón entrampados en el tártaro dental de dos individuos inhumados en las Tumbas 1 y 2 del sitio Esquina de Huajra. Se identificaron fibras vegetales, granos de almidón y fitolitos de cultivos andinos (poroto y maíz). En el caso de los granos de almidón modificados, se pudo describir daños producidos por calor en seco y en húmedo (i.e. tostado, hervido). A estos estudios se sumó el análisis morfofuncional del equipamiento culinario (vasijas cerámicas) hallado en el asentamiento con el fin de avanzar en hipótesis acerca de los modos de preparación/cocción de los cultivos identificados.

A partir de dos intervenciones forenses se exponen los aportes de la arqueología en el proceso de gestación y desarrollo del campo técnico y científico judicial que investiga la violencia política y los crímenes de lesa humanidad en la provincia de Tucumán (Argentina) que tuvo lugar entre los años 1975 y 1983. Tal circunstancia —es decir, que la disciplina arqueológica haya sustentado la conformación del ámbito forense local—, se sugiere, imprimió un carácter particular a la práctica forense que investiga este período. Se propone exponer la experiencia tucumana al centrarse en los resultados parciales de dos investigaciones forenses y en las que los aportes de la arqueología fueron claves para dimensionar las características que asumió el exterminio en Tucumán.

Authors: Rengkuan Mariana , Leasa Marleny , Sumampouw Herry Maurits 
Published: March 2023

This study aimed to determine the effects of project-based learning in the Covid-19 pandemic era on biology students' metacognitive and critical thinking skills in the genetics concept. The research model used was a quasi-experimental design. The population in this study were fifth semester students who offered genetics courses consisting of 4 classes A to D. Samples were taken randomly, that is classes A and B. The data were analyzed using the Anacova. The results show that students with the PjBL model have better metacognitive skills and thinking skills than those with conventional learning models. The PjBL model could be used as a reference to improve the metacognitive and critical thinking skills. Therefore, further research can be used to examine PjBL learning models on other higher thinking skills such as collaboration skills, problem-solving skills, and creative thinking skills.
Keywords: project-based learning, metacognitive skills, critical thinking skills, genetic study
Aging of the population and the quality of life
Authors: Gardocka-Jałowiec Anna , Szalonka Katarzyna 
Published: March 2023

The paper aims at presenting the quality of life in terms of the deepening population aging process conditioned (to a great extent) by the progressive convergence of technologies. The interdisciplinary, theoretical nature of the considerations is a voice in the discussion on the interpretation, place, and role of quality of life, with particular emphasis on the extension of human life as a consequence of medical development.
The authors applied the descriptive analysis method to present the category of quality of life, the phenomenon of population aging, the specificity of technological changes, and selected issues in the field of demographic changes. Polish and foreign literature on the subject was the basis for the considerations. The theoretical aspect of the research is supplemented by the empirical part supported by available secondary data published by Eurostat and Statistics Poland (Główny Urząd Statystyczny).
Poland has been in the top thirty demographically old countries in the world for many years. In 1967, it crossed the threshold of demographic old age, and in 1980 — the threshold of advanced demographic old age. The demographic forecasts of Statistics Poland indicate that the number of people in retirement age will increase, and in 2035, it will reach 26.7% of the population. The observed and forecasted decline in the total population and the growth in the number of people in the senior age lead to an increase in the demographic dependency ratio of the elderly.
The convergence of technologies revealed in medicine creates a new perspective on the population aging process. Extending human life allows one to recognize that the quality of life becomes: 1. the most desirable result of all healthcare policies; 2. dependent on the change of the healthcare model, i.e., the transition from the dominant model of reactive and retrospective care to the desired proactive and prospective model.
Rola przywództwa w rozwiązywaniu problemu wypalenia zawodowego w placówce medycznej
Authors: Tańska Ewa 
Published: March 2023

Wypalenie zawodowe w placówce medycznej, szczególnie na pierwszej linii świadczenia usługi medycznej i po trudnym czasie pandemii COVID-19, jest pilnym wyzwaniem, które przywódcy powinni zrozumieć i bezpośrednio rozwiązać.
Celami artykułu są: 1) poznanie przyczyn oraz wpływu zmęczenia i wypalenia zawodowego na człowieka; 2) określenie roli przywództwa w tworzeniu kultury organizacyjnej opartej na angażowaniu zespołów i promującej dobre samopoczucie pracowników w placówce medycznej oraz 3) zaproponowanie strategii budowania atmosfery wzajemnego wsparcia oraz zapobiegania zmęczeniu i wypaleniu zawodowemu.
Metodą badawczą są przegląd i analiza literatury branżowej, w tym artykułów w międzynarodowych czasopismach oraz materiałów ze szkoleń.
W literaturze przedmiotu istnieje wiele deﬁnicji zjawiska wypalenia zawodowego. Jest to zespół wyczerpania emocjonalnego, depersonalizacji i obniżonego poczucia dokonań osobistych. W przypadku personelu medycznego depersonalizacja pacjentów może początkowo wyrażać się w tendencji do unikania osób chorych i skracania czasu spędzanego z nimi.
Czynnikami pierwotnymi wpływającymi na występowanie wypalenia zawodowego są brak uczciwości i wzajemnego szacunku, obciążenia, którymi nie można zarządzać, brak jasności ról, słaba komunikacja lub brak wsparcia ze strony przełożonego, nieuzasadniona presja czasu i brak ludzi do pracy, brak znaczących relacji międzyludzkich. Czynnikami, które pojawiły się w czasie pandemii, są rosnące zaległości, oczekiwanie na oddelegowanie do innej pracy oraz tak zwany koszt emocjonalny.
Kluczową rolą liderów na różnych szczeblach w hierarchii jednostki jest tworzenie kultury szacunku i ciągłego doskonalenia, która integruje członków zespołu we wzajemnym wspieraniu się w najtrudniejszych momentach pracy zawodowej. Niezwykle ważne jest wdrażanie strategii promujących budowanie i utrzymywanie dobrego samopoczucia i odporności pracowników na stres. Strategie te powinni indywidualnie do swoich potrzeb tworzyć ludzie, którzy doświadczają syndromu wypalenia. W zespołach medycznych warto zastanowić się, co personel medyczny zawdzięcza pacjentom, i ponownie dokonać oceny wartości, zbudować ich hierarchię i przemyśleć, co w życiu jest prawdziwe i cenne. Aby dojść do tak ważnych wniosków, niejednokrotnie trzeba omówić sprawy trudne i bolesne.

Published: March 2023

Purpose: To show horizon to use new kind of public urban transport -autonomous tire tram of Phileas system
without guide middle rail and catenarian, with magnetic-electronic steering system application – as more
attractive for passengers than regular tram for urban transportations to free city lines from car jams. Methods:
Analysis and generalization of work experience of leading enterprises, which exploit given kind of transport, of
such countries as Netherlands (Eindhoven, Amsterdam), France (Due), Germany (Cologne), Turkey (Istanbul)
as well as South Korea and so on, were held. The analysis of the most progressive constructions, applied in
given vehicle, has been fulfilled. Results: Enterprise work experience has proved the feasibility to use tire tram
wagons without guide rail for cities but revealed whole series of drawbacks, connected with the imperfections
of the work of magnetic-electronic steering system that has whole row of irremovable flaws. Phileas rolling
stock has demonstrated itself as insufficiently reliable in exploitation that has led to its gradual premature
withdrawal and change with regular articulated buses, i.e. its conversion from a tram to usual BRT system.
Practical significance: The use of tire tram autonomous system without guide rail and catenerian has good
look-outs in cities but it’s necessary to apply more up-to-date element base for steering with the use of artificial
intelligence technology. Phileas transport system has simply got ahead of its time. It’s worth not to refuse from
the development of existing classical trams and light transport and the design of their new systems.
Deep Gluteal Pain Syndrome
Authors: Parodi Dante , Villegas Diego , Escobar Gonzalo , Bravo José , Tobar Carlos 
Published: March 2023

Background:
Sciatic nerve entrapment is an entity that generates disabling pain, mainly when the patient is sitting on the involved side. According to some studies, the presence of fibrovascular bands has been described as the main cause of this pathology, and the sciatic nerve’s decompression by endoscopic release has been described as an effective treatment generally associated with a piriformis tenotomy. The aim of this study was to present the medium-term functional results of endoscopic release of the sciatic nerve without resection of the piriformis tendon.

Methods:
This prospective, observational study included 57 patients who underwent an endoscopic operation for sciatic nerve entrapment between January 2014 and January 2019. In all cases, a detailed medical history was obtained and a physical examination and a functional evaluation were performed using the modified Harris hip score (mHHS), the 12-item International Hip Outcome Tool (iHOT-12), and the visual analog scale (VAS) for pain. All patients had pelvic radiographs and magnetic resonance imaging (MRI) scans of the hip on the involved side and underwent a prior evaluation by a spine surgeon.

Results:
This study included 20 male and 37 female patients with a mean age of 43.6 years (range, 24 to 88 years) and a mean follow-up of 22.7 months. The median mHHS improved from 59 to 85 points. The median iHOT-12 improved from 60 to 85 points. The median VAS decreased from 7 to 2. Postoperative complications occurred in 12% of patients: 1 patient with extensive symptomatic hematoma, 3 patients with hypoesthesia, and 3 patients with dysesthesia.

Conclusions:
Endoscopic release of the sciatic nerve by resection of fibrovascular bands without piriformis tenotomy is a technique with good to excellent functional results comparable with those of techniques in the literature incorporating piriformis tenotomy.

Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
Physics-Constrained Neural Network (PcNN): Phase Behavior Modeling for Complex Reservoir Fluids
Authors: Li Yiteng , He Xupeng , Zhang Zhen , Alsinan Marwa , Kwak Hyung , Hoteit Hussein 
Published: March 2023

AbstractThe highly nonlinear nature of equation-of-state-based (EOS-based) flash calculations encages high-fidelity compositional simulation, as most of the CPU time is spent on detecting phase stability and calculating equilibrium phase amounts and compositions. With the rapid development of machine learning (ML) techniques, they are growing to substitute classical iterative solvers for speeding up flash calculations.However, conventional data-driven neural networks fail to account for physical constraints, like chemical potential equilibrium (equivalent to fugacity equality in the PT flash formulation) and interphase/intraphase mass conservation. In this work, we propose a physics-constrained neural network (PcNN) that first conserves both fugacity equality and mass balance constraints. To ease the inclusion of fugacity equality, it is reformulated in terms of equilibrium ratios and then introduced with a relaxation parameter such that phase split calculations are extended to the single-phase regime. This makes it technologically feasible to incorporate the fugacity equality constraint into the proposed PcNN model without any computational difficulty.The workflow for the development of the proposed PcNN model includes four steps. Step 1: Perform the constrained Latin hypercube sampling (LHS) to generate representative mixtures covering a variety of fluid types, including wet gas, gas condensate, volatile oil, and black oil. Step 2: Conduct PT flash calculations using the Peng-Robinson (PR) EOS for each fluid mixture. A wide range of reservoir pressures and temperatures are considered, from which we sample the training data for each fluid mixture through grid search. Step 3: Build an optimized PcNN model by including the fugacity equality and mass conservation constraints in the loss function. Bayesian optimization is used to determine the optimal hyperparameters. Step 4: Validate the PcNN model. In this step, we conduct blind validation by comparing it with the iterative PT flash algorithm.

Published: March 2023

SummaryEnsuring cement sheath placement is of paramount importance for the success of a primary cementing operation. Poor mud displacement and fluid contamination can lead to cement isolation failure, loss of production, and even well abandonment. Over time, many cement placement computerized models have been developed, leading to a significant number of theoretical and case history papers. However, using these to design a cement job is difficult because their physical and mathematical assumptions are most of the time unclear, and because their application requires balancing precision with computation time. Models that are too precise may lead to very long runs, while oversimplified models could result in nonpredictive simulations. To the authors’ knowledge, nothing has been published to explain how to perform efficient predictions with a cement placement computerized model. Such is the object of this paper. It presents an extensive analysis of all the available cement placement computerized models, highlighting their advantages and disadvantages and listing their assumptions. This analysis indicates that (1) the actual methods used to estimate the equivalent circulating density window are not rigorous enough; (2) there still exist a lot of uncertainties when predicting the tubular standoff; (3) modeling fluid contamination, especially when the fluids are not compatible, remains very cumbersome, if not impossible, because the true interfaces’ physics is not completely considered; (4) a local contamination observed at an intermediate time can disappear at the end of the simulation due to numerical diffusion, meaning that just looking at the concentration maps at the end of placement is not sufficient to judge the efficiency of a displacement scenario; and (5) changes in geometries along the cement sheath are not considered with precision. This work allows establishing guidelines to help understanding how to manage simulation inputs and analyzing and communicating the produced results.
A Novel Approach for the Selection of Cluster-head and Energy Efficient Routing
Authors: Kamaruzzaman Md , Chandra Abhijit 
Published: March 2023

Abstract
During last few years, extensive research had been carried out to enhance the lifetime of wireless sensor network. However, most of the approaches centred on energy efficiency to prolong the lifetime of the network but kept quiet about normalization of conditional parameters which is equally significant to minimize the energy consumption of the overall network. In this paper, we propose efficient cluster head selection as well as proper cluster formation and energy efficient and energy balance routing which is premised with normalized condition parameters. For selecting the cluster head efficiently, we introduce an energy efficient algorithm using normalized conditional parameters. Subsequently, an efficient load balanced clustering algorithm using normalized conditional parameters has been proposed to increase the lifespan of sensor network. Finally, we propose the energy efficient and energy balanced routing algorithm considering normalized conditional parameters. We also propose the LP formulation for the clustering and routing problem. Proposed algorithm has been simulated and the results are compared in terms of relevant metrics such as network lifetime, time for first node die, dead sensor nodes etc. with some of the existing algorithms to show the effectiveness of the proposed work.
Comprehensive analysis of the immune effect of the NAT10 in the Head and Neck Squamous Cell Carcinoma
Authors: Li Xiaohui , Li Sen , Hu Wenjian 
Published: March 2023

Abstract
Background: Head and neck squamous cell carcinoma, the most common malignancy in the world. NAT10 plays an important role in regulating tumor cell proliferation, migration, invasion, and cell cycle, thereby promoting tumor growth and progression. However, the immunological role of NAT10 in HNSCC has not yet been reported.
Methods: In this study, we first analyzed the oncogenic role of NAT10 in HNSCC. Next, we analyzed the relationship of the NAT10 gene with immune cells in HNSCC and discussed its relationship with the immune micro-environment. Finally, immunomodulators and immune genes associated with NAT10 were identified by the TISIDB and X-tile software, and a predictive model was developed to evaluate the survival status of HNSCC patients.
Results: In this study, we found that NAT10 is over-expressed in Head and neck squamous cell carcinoma (HNSCC) by analyzing the data available in The Cancer Genome Atlas (TCGA); this finding can be used to predict poor patient prognosis. The results of our multivariate COX regression analysis indicated that the highly expressed NAT10 gene was able to act as an independent risk factor for poor prognosis in HNSCC patients. The regression analysis indicated that the expression level of NAT10 was significantly related to the expression level of related signaling pathways, immune-infiltrating cells, immune checkpoints, and tumor mutation load level in HNSCC; immune efficacy and drug efficacy were impacted as well. Next, we systematically analyzed the relationship between NAT10 expression levels and related signaling pathways, immune checkpoints, immune-infiltrating cells, immune efficacy, drug efficacy, etc. We identified 12 immune genes associated with NAT10 by TISIDB and X-tile software and subsequently developed a predictive model of related immune genes. Finally, the survival status of the HNSCC patients was predicted using the constructed nomogram, and the model was evaluated by the ROC curve and the calibration curve (based on the risk score). The results demonstrated that the area under the curve (AUC) predicting 1-,3-, and 5-year overall survival was 0.716, 0.749, and 0.668, respectively, suggesting good predictive accuracy and that the resulting calibration curve compared with the ideal model.
Conclusions: NAT10 is highly likely to be a larvaceous immune target for HNSCC, and the associated immune genes may be promising prognostic biomarkers in HNSCC.
