Authors: Manojkumar Kaliyannan , Kandeeban Rajagopalan , Batoo Khalid Mujasam , Hussain Sajjad , K Saminathan
Published: June 2023

This investigation highlights the successful synthesis and comprehensive characterization of a robust and reliable copper-based electrocatalyst, with an emphasis on its exceptional performance in hydrogen evolution reaction (HER). Copper oxide, silicon dioxide, and graphite were synthesized and advanced characterization techniques such as XPS, FT-IR, XRD, SEM, and EDS were employed to thoroughly analyze the synthesized materials. The resulting copper nanoparticles supported on silica substrate exhibited a calculated Tafel slope of 37 mV/dec in 0.5 M of H2SO4 solution. Furthermore, a mathematical model based on the Tafel equation and Langmuir-Hinshelwood model was developed to describe the HER reaction kinetics of an electrocatalysts in aqueous solution, which displayed improved HER performance due to its larger active surface area. The composite exhibited high probability for HER in a wide pH range and applied potential, with the composite R2 demonstrating the best stability under reaction conditions. These findings suggest that the copper-based electrocatalyst has significant potential to reduce the cost of producing hydrogen fuel and promote environmentally friendly energy sources.

Published: June 2023

Hydatid disease is very common around the Mediterranean basin and endemic in some parts of the world. Cerebral involvement remains rare, represents only about 2% of all hydatid localizations and mainly affects the pediatric population. Extradural hydatid cyst is very rare or even exceptional when it is associated with or followed by intracerebral disseminations. Here, the authors report a new exceptional case of an early multiple intra-axial hydatid dissemination in a 5-year-old North African male patient from a rural governorate who underwent surgery 3 months ago for a primary osteolytic extradural and complicated hydatid cyst with good clinical and radiological outcomes.

Published: June 2023

Teenage pregnancy poses significant challenges for young women and their children, particularly in developing countries. This study examined the social determinants of health (SDoH) associated with teenage pregnancy and explored postpartum outcomes, including contraceptive use, education, job prospects, and repeat pregnancies. A cross-sectional study was conducted at a tertiary care center in Monterrey, Mexico, with a follow-up survey administered three years later.
The initial sample included 228 adolescents (<19 years old) receiving obstetric or prenatal care at the hospital. Socioeconomic factors such as poverty, unfavorable neighborhood conditions, and low parental education were prevalent among participants. While most intended to continue their education after childbirth, at the beginning of the study only 51% were still enrolled in school. The time span between sexual activity and the first pregnancy was short, indicating early sexual initiation.
Although most participants were aware of contraceptive methods, 27% reported never using contraception. School-based sex education was the primary source of information but lacked comprehensive coverage. Moreover, 44% did not plan to become mothers, highlighting the need for improved access to safe abortions and comprehensive sexual education. In the follow-up survey, 33% experienced repeat pregnancies within three years. Contraception issues, financial dependency, and limited access to contraceptive services contributed to unintended pregnancies.
Addressing social, economic, and cultural factors is crucial in reducing teenage pregnancy rates. Comprehensive sex education programs should cover diverse topics such as sexual diversity, healthy relationships, and violence prevention. Additionally, expanding access to safe abortion services and improving contraceptive counseling is vital. Targeted interventions are needed to challenge societal beliefs and cultural factors surrounding teenage pregnancy. By addressing these determinants and providing comprehensive reproductive health services, policymakers and healthcare providers can enhance the well-being and future prospects of young women affected by teenage pregnancy.
Perceptions and experiences of fertility preservation in Greek female cancer patients
Authors: Taniskidou Anna-Maria , Voultsos Polychronis , Tarlatzis Vasileios , Timotheadou Eleni
Published: June 2023

Background
As advances in oncology have led to remarkable and steady improvements in the survival rates of cancer patients and anticancer treatment can cause premature ovarian failure in women, fertility preservation has become a global public health concern and an integral part of the care for women diagnosed with cancer during reproductive age. However, for various reasons, fertility preservation remains underutilized for cancer patients. There are substantial gaps in our knowledge about women’s experience and perceptions on the issue. This study aims to contribute to bridging that gap.
Methods
This prospective qualitative study was conducted from March 2018 to February 2023. A combination of purposive and snowball sampling was used. Data were collected by semi-structured interviews with nineteen reproductive-age women with a recent cancer diagnosis. Data were classified and analyzed by a thematic analysis approach.
Results
A variety of distinct themes and subthemes emerged from the analysis of the interview data. The cancer diagnosis emerged as a factor that considerably affects the women’s attitudes towards biological parenthood: It can further increase their (strong) previous desire or decrease their previous (weak) desire. Women with a recent cancer diagnosis did not receive adequate and multidisciplinary counselling, including clear and sufficient information. However, participants felt satisfied from the information they received because they either received the information they requested or remained in denial to get informed (i.e. because they felt overwhelmed after the cancer diagnosis). Embryo cryopreservation emerged as a less desirable fertility preservation option for women with cancer. Participants showed respect for human embryos, not always for religious reasons. Surrogacy emerged as the last resort for most participants. Religious, social or financial factors did play a secondary (if any) role in women’s decision making about fertility preservation. Finally, male partners’ opinions played a secondary role in most participants’ decision-making about fertility preservation. If embryo cryopreservation was the selected option, partners would have a say because they were involved with their genetic material.
Conclusions
The findings that emerged from data analysis were partly consistent with prior literature. However, we identified some interesting nuances that are of clinical importance. The results of this study may serve as a starting point for future research.
Relationship between rheological properties of rice flour paste and printability of 3D food printer
Authors: Kamata Tatsuki , Nei Daisuke
Published: June 2023

3D food printers(3DFPs) are attracting interest due to the potential to create a new type of personalized food, and rice flour has the potential to be used in 3DFPs as a gluten-free carbohydrate food.
Rice flour with various properties and different moisture pastes were prepared and extruded from a 3DFP.
For all types of rice flour, it was found that paste with a high flow stress value(higher than 2303 Pa) could not be extruded from the nozzle and that paste with a low flow stress value(lower than 40 Pa) could not retain its shape after extrusion.
Weak gel model analysis of rice flour pulverized by a dry jet mill showed an unchanging and high coordination number, which appeared to be related to the shape stability.
The relationship between the rice flour paste and printability can be explained by rheological measurement results and the paste character can be controlled by changing the pulverization method and water addition amount.

Authors: Long Zhisheng , Gong Feipeng , Xiong Long , Wen Jiabing , Chen Gang
Published: June 2023

Objective:The risk of Osteoporotic Vertebral Collapse(OVC) associated with delayed neurological dysfunction(DND) is high, and surgery for it in the elderly is challenging. How to simplify surgical procedures while preserving surgical efficacy has become a hot topic in treatment. This study aims to provide clinical data to support the advancement of modified posterior osteotomy for the treatment of thoracolumbar OVC with DND by comparing perioperative clinical parameters, imaging data characteristics and changes in efficacy outcome indicators.Methods:12 patients were diagnosed for Osteoporotic Vertebral Collapse in combination with neurological dysfunction. Modified Posterior osteotomy in all patients were designed. The perioperative, and radiological parameters and complications, including surgery duration, blood loss, ASIA grade,VAS, ODI, Regional Kyphosis Angle(RKA), Anterior Vertebral Height ratio(AVHr), Spinal Canal Invasion ratio(SCIr) , were collected retrospectively and analyzed to evaluate the clinical efficacy and safety of this technique.Results:Of the12 patients, Mean age: 65.50 ± 9.70 years, mean follow-up: 29.42 ± 4.98 months, mean operative blood loss: 483.33 ± 141.96 ml, mean operative time: 3.71 ± 0.66 hours, VAS score decreased from preoperative 5.83 ± 0.72 to final follow-up 1.25 ± 0.75 (P<0.05). Post-operative ODI reduced to 31.46%, and postoperative neurological function was significantly improved. The RKA was corrected from 35.8±10.83° to 20.03±3.54° after surgery and to 22.47±3.08° at final follow-up; AVHr% was corrected from 39.32±18.02 to 63.03±14.29 after surgery and to 53.89±8.94 at final follow-up; SCIr% was corrected from 54.88±5.41 to 68.13±5.30 after surgery and to 68.68±6.76 at final follow-up; Spinal canal volume immediately following surgery was increased by 24.14%.Conclusions:Posterior modified osteotomy is an effective treatment for thoracolumbar osteoporotic fractures with OVC combined with DND. It can significantly preserve vertebral height, increase vertebral canal volume, correct kyphotic angle, and improve postoperative neurological function. The simplified osteotomy also has certain advantages in terms of operating time, blood loss, postoperative VAS score and improvement in lumbar function.

INTRODUCTION
Benign tracheobronchial stenosis is a abnormal tracheal lumen narrowing that may incur progressive dyspnea and life-threatening hypoxemia. There is no consensus on which patients should be treated with endoscopic or surgical method. This study investigates the outcomes bronchoscopic dilatation for treating benign tracheal stenosis using a device equipped with a blade to cut the stenotic lesions with dense fibrosis.
MATERIALS AND METHODS
The procedure was carried out in an operating room under general anesthesia. All patients were intubated with a Rigid Bronchoscope (RB) placed just above the stenosis. Through Rigid Bronchoscopy combined modalities were used as needed: radial incisions of the mucosal stenosis with blade at the levels of 4, 8 and 12 o’clock, with back and forth movements, then the stenotic area was dilated more easily with a rigid bronchoscope. Dilatation was performed by passing the RB through stenotic areas of increasing diameter and then Balloon dilation of increasing diameter. There were no complications during the procedure.
RESULT
We conducted an observational, retrospective, single-centre study in the Thoracic Surgery Unit of the University of ‘Luigi Vanvitelli’ of Naples from November 2011 to December 2022. We included all consecutive patients with benign tracheal stenosis inoperable. During the study period, 113 patients were referred to our department with benign tracheal stenosis inoperable. 61 patients were treated with the blade. During the follow-up, a recurrence of the stenosis was observed in 8 patients in the first month and in 4 patients in the third month. Instead in the patients treated with the use of laser (59 patients), during the follow-up a recurrence was observed in 16 patients in the first month and in 6 patients in the third month; no patient relapsed after 6 months and after 1 year. Long term successful bronchoscopic management with blade was attained by 99 % in simple and 93% in mixed stenosis and in complex type stenosis.
CONCLUSION
Our study underlines the importance of the use of the blade in bronchoscopic treatment as a valid conservative approach in the management of patients with inoperable benign tracheal stenosis as an alternative to the use of the laser, reducing the abnormal inflammatory reaction in order to limit recurrences.
A Quality Driven Framework for Decomposing Legacy Monolith Applications to Microservice Architecture
Authors: Hasan Muhammad Hafiz , Osman Mohd Hafeez , Admodisastro Novia Indriaty , Muhammad Muhamad Sufri
Published: June 2023

Transforming monolith applications to microservice architecture is a common cloud migration strategy for businesses to accomplish cloud-native benefits. However, decomposing monolith applications is a challenging task that requires experience, skills, and dedication to initiate this process, and often, the migrated product quality is neglected. The lack of relevant guidelines on the design quality for distributed cloud environment architecture such as microservice further exacerbates this concern. We propose a quality-driven decomposition framework for migrating monolith applications to the cloud-native architecture. Our approach implies six activities in decomposing monolith applications from the source code to the microservice architecture. This framework supports various architectural design properties related to maintainability quality. Furthermore, this framework enhances the machine learning approach to enable automatic microservice identification, hence evaluating the design quality using a scoring-based approach. We use five applications to evaluate our approach, and the results show that our framework can provide insightful judgment to the designer regarding microservice design quality.

Published: June 2023

Introduction
The robotic platform compared to laparoscopy has proven to have similar postoperative outcomes, however its adoption in the middle east has been slow and there is limited data regarding outcomes with its use in small newly established robotic colorectal programs. Our aim is to report our experience and outcomes of robotic colorectal surgery performed by fellowship-trained robotic colorectal surgeons and compare it to larger more experienced centers.
Methods
This is a retrospective review of prospectively collected data between 11/2021 to 03/2023 from Jaber Al Ahmad hospital, a tertiary health care referral center. The study cohort included 51 patients who had robotic colorectal surgery. The outcomes were overall morbidity, serious morbidity, mortality, conversion to open, length of hospital stay and the quality of oncological specimen.
Results
Of 51 robotic colorectal surgery, our overall morbidity was 31.4% (n = 16 patients). Only 9.8% (n = 5) had serious morbidity of which three required interventions under general anesthesia. Our median length of hospital stay was 6 days (IQR = 4), and we had no mortality. Of 17 proctectomies for rectal cancer, we had 88% complete total Mesorectal excision, 15 of them were R0 resections, and our median lymph node harvested was 14 (IQR = 7). All our colon cancer resection had R0 resection and median lymph nodes harvested was 21 (IQR = 4). We had two conversion to open and no mortality.
Conclusions
The morbidity, mortality, conversion rates, and pathological specimens’ quality in new small robotic colorectal programs led by fellowship trained robotic colorectal surgeons can achieve comparable results to larger more established programs.
WITHDRAWN: Planning Forest Recreation Services for Urban Dwellers With a Multi- Criteria Approach (a Case of Türkiye)
Authors: YILMAZ Murat , BUĞDAY Seda ERKAN
Published: June 2023

Due to its geography, Türkiye has recently been exposed to extensive refugee migration and hosts many refugees. In addition, like the rest of the world, it has faced the challenges of the Covid-19 pandemic. Alongside these unfavorable situations, life continues, and people's orientation toward the services offered by forests and the planning of services are becoming more and more important every day. For this reason, this study focused on recreation, which is one of the non-wood forest products and services offered in forests in Türkiye. The distribution of national parks, nature parks, and A-, B-, C-, and D-type recreation areas, which are recreational areas in forests, were evaluated by weighted overlay analysis at the provincial level in Türkiye, using criteria such as Gross Domestic Product GDP per capita, number of people per km2, population growth rate, ratio of forest area to overall area, and total forest recreation areas. As a result of the analysis, the provinces were divided into three priority categories. Considering Türkiye's national development policies, different approaches are presented to planners in this study regarding organizing the utilization of forest service’s according to changing needs by evaluating the changing characteristics of the society and the forest structure together.
Rescate y análisis de Carta a un obrero de fray Pedro Bustos, OFM.
Authors: Alvarado Sánchez Nelson Manuel
Published: June 2023

La carta ficticia es el género literario elegido por fray Pedro Bustos, religioso franciscano chileno, para representar la realidad de pobreza material y moral del obrero y su familia y difundir su visión crítica sobre la sociedad, los partidos políticos y la Iglesia en Chile, en las primeras décadas del siglo XX. En ellas es posible encontrar los elementos esenciales del pensamiento social católico, la caracterización de la familia proletaria de Santiago de Chile, el examen de las causas de la malas condiciones morales y económicas de los obreros, y la relación entre abandono de la fe y la crisis social. Su autor las escribió realizando un ejercicio entre una formación filosófica y la experiencia personal nacida de una cercanía personal y pastoral con las clases vulnerables y éstas fueron publicadas en las revistas franciscanas, entre cuyos lectores estaban los laicos adherentes a su espiritualidad a nivel nacional. El rescate de estas es necesario pues al ser considerado un género literario menor puede pasar desapercibida o ignorada en las diversas investigaciones sobre las posturas eclesiales, la realidad chilena y el estado de las clases proletarias.
Autonomía sin atropello y responsabilidad que emancipa
Authors: García Aguilar Juan Francisco
Published: June 2023

La riqueza de una dimensión humana como la libertad merece el compromiso de cuidar de ella, y nuestra manera de atender a esta tarea pone a prueba el valor que le conferimos a nuestro propio ser. El pasar por alto este cometido se traduce en una experiencia de atropello, que termina por enrolarnos a todos en un interminable ciclo de hostilidad. Albert Camus nos ofrece una mirada que nos permite reconocer el mérito de ocuparnos de nuestro ser libre, sin atribuirle a nuestra libertad un carácter absoluto bajo el que se esconde la intención de obtener un provecho sobre los demás. De manera que nuestra libertad se realiza en la medida en que nos proporciona un bien que no es monopolio de ninguno, al contrario, beneficia a cada quién en tanto que lo hemos alcanzado en conjunto.

La educación como un diálogo de corazón a corazón. El caballo y los ojos en el De Anima et Resurrectione
Authors: Jaramillo Vargas Gabriel Alberto
Published: June 2023

En la intimidad del diálogo de corazón a corazón entre Macrina y Gregorio en el De Anima et Resurrectione, se puede percibir no sólo una dialéctica: pathos–logos, maestro-discípulo, fe-ciencia; sino también, una estructuración del diálogo inspirada en el Fedro, en la que tras la tesis y la antítesis, se busca como fruto pedagógico del diálogo una síntesis de los elementos en cuestión. Este trabajo analizará los símbolos del caballo y los ojos, su relación en términos pedagógicos y mistagógicos, así como la posibilidad de entender la educación como un diálogo cor ad cor. Estos dos dispositivos retóricos que también están presentes en De Vita Moysis e In Canticum Canticorum, le permiten al Niseno dialogar con la filosofía y la Sagrada Escritura en medio de su quehacer teológico. En este sentido, se analizará la introducción al diálogo, explorando también la estructura del discurso y su relación con el Fedro (1), para luego analizar los símbolos del caballo y los ojos (2), estableciendo algunas relaciones con De Vita Moysis e In Canticum Canticorum que permiten profundizar en la pedagogía cor ad cor de Macrina hacia Gregorio (3), para finalizar con una breve conclusión.

Authors: Podolchak Nazar , Bilyk Olena , Karkovska Veronika , Tsygylyk Natalia , Vesolovska Mariia
Published: June 2023

This study aims to establish the advantages and disadvantages of various methods for assessing emotional intelligence by comparing the most common methods in leading countries and a developing country (Ukraine) in business, as a field in which the level of emotional intelligence importance is generally recognized, and in the public administration sphere. The MSCEITV2.0 and Hall tests were chosen as the most accurate tests for determining the emotional intelligence of public managers. For a more detailed comparison of these two tests and the selection of a universal one, 100 respondents were surveyed using a questionnaire developed in Google Forms. The sample included officials of local governments in the western, northern, and central regions of Ukraine, as well as representatives of businesses in the same regions, particularly managers of private enterprises. The results indicate that these two tests show similar results when determining the level of emotional intelligence. However, when allowed to choose the testing method, 80% of public managers and business representatives chose the Hall test, which takes less time than the MSCEITV2.0 test. Considering the obtained results and the permissible error, the study identifies the Hall test as a universal method for determining the emotional intelligence of public managers in a developing country – Ukraine.

Intravenous Amiodarone-induced Acute Liver Failure: A Case Report and
Literature Review
Authors: Bteich Yara , Hosri Jad , Nauphal Nagi , Ibrahim Nour
Published: June 2023

Background:

Hepatotoxicity of amiodarone has long been described and consists mostly of mild and delayed onset elevation in liver function tests. Fulminant hepatitis, however, is much rarer and attributed to the parenteral administration of the drug. The mechanism of injury is yet to be understood, though multiple theories have been proposed. This case report aims at highlighting the importance of monitoring patients receiving intravenous amiodarone therapy to detect severe acute liver injury and showcase the appropriate management thereafter.

Case Description:

Our patient is a 79-year-old male who presented with epigastric pain that was crampy, intermittent, and aggravated upon exertion. His heart rate was 93 beats/min and cardiac auscultation revealed an irregular heart rhythm. His electrocardiogram revealed atrial fibrillation. He was given intravenous amiodarone with a total dose of 950 mg and developed acute liver failure with extremely elevated liver function tests 48 hours after initiating the drug. After discontinuation, liver function tests returned to baseline within 10 days and the patient was discharged home.

Conclusion:

Physicians should be aware of the potentially life-threatening complications, including severe acute liver injury, by closely monitoring liver function tests following the administration of the drug and immediately discontinuing therapy if toxicity was detected.
Structural Elucidation, In vitro and In silico Biological Evaluations of New
Fluorinated Chalcone Derivatives for Potential Antioxidant Activity
Authors: Rajasagaran Rineswary , Mohamad Arshad Ahmad Saifuddin , Azizi Juzaili , Mohd Nizar Siti Nabilla Aliya , Arshad Suhana
Published: June 2023

The newly synthesized fluorinated chalcone derivatives are observed to possess antioxidant
potential. Two new fluorinated chalcone compounds were effectively synthesized using the Claisen-
Schmidt condensation reaction and were recrystallized using the slow evaporation method. The single
crystal structure of the compounds was determined and refined through the X-ray single crystal diffraction
method. All compounds were subjected to computational structural characterization and
Hirshfeld surface analysis. The compounds were then further characterized through the Ultravioletvisible
(UV-Vis) spectroscopic study. The chalcone derivatives were further analysed with biological
experimentation and simulation such as in vitro antioxidant (DPPH) assay, molecular docking and in
silico ADMET study. The crystal packing revealed that the molecules in the compounds were linked
together through the intermolecular C—H···O and C—H···π interactions. Hirshfeld surface analysis
validated the presence of intermolecular interactions in crystal packing. The UV-Vis spectroscopic
study revealed that the absorption wavelength of the compounds that range from 421.79 to 428.98 nm
was within the visible region with the energy gap value of 2.58 to 2.62 eV. The DPPH assay disclosed
weak antioxidant activity of both compounds (-31 to 20 %, 10000 μg/mL) compared to the standard
ascorbic acid (94.5 %, 50 μg/mL). The binding energy of the docked complex inside the target protein,
2CAG was within the range of -7.3 to -7.5 kcal/mol. In the silico model, SwissADME predicted
that the two compounds have overall good drug-like properties. Different substituents, more planar
configuration and high intramolecular interactions in the crystal packing played their role in increasing
the antioxidant activities, binding energy and drug likeliness of the synthesized compounds.
Characterization of a High-performance PCF-SPR Sensor for Biomedical
Applications
Authors: Pradhan Himansu Shekhar
Published: June 2023

Background:

Surface plasmon resonance (SPR) based fibre optic sensors are becoming increasingly
popular in biomedical applications. However, the sensor performance is degraded because of
low sensitivity with inadequate detection accuracy and figure of merit.

Objectives:

The first objective of this study is to design a D-shaped photonic crystal fibre (PCF) using
COMSOL multiphysics. The second objective is to enhance the performance of the designed sensor in
terms of sensitivity and detection accuracy using single and dual metal layer structures. In addition, the
performance of the proposed sensor is compared with the existing one.

Methods:

In this study, the performance of the PCF-SPR sensor is improved using a D-shaped photonic
crystal fibre (PCF) and two metals as grating layers. The work in this paper is divided into two parts. In
the first part, the gold metal layer with optimized thickness is used to achieve good sensitivity. In the
second part, the combination of gold and silver dual metal layers with optimized thickness is used to
achieve good detection accuracy. Moreover, the performance of the proposed sensor is compared to other
published D-shaped PCF sensors.

Results:

The proposed D-shaped PCF-SPR sensor is designed and simulated using COMSOL multiphysics.
The results in terms of sensitivity (S) and detection accuracy (DA) are obtained using a single metal
layer and dual metal layers with optimum thickness. Moreover, the transmission coefficient and loss
curve have been calculated using different refractive indices of the material. In addition, the simulation
results are validated for cancer detection using the proposed sensor.

Conclusion:

An improvement of the D-shaped PCF sensor for cancer detection is presented in terms of S
and DA using single or dual metal layer structures and COMSOL multiphysics. In a single metal layer
structure, only gold is used as a grating layer, and the thickness of the grating layer is optimized for
achieving high sensitivity. Similarly, a combination of gold and silver is used as the grating layer in the
dual metal layer structure for achieving a high DA. Moreover, the obtained results of the proposed PCFSPR
sensor are compared with the published results and found that the proposed sensor can be used with
a high degree of S and DA for biomedical applications and also can be used in the bio-sensing field.

The importance as well as the impact that performance evaluation may have on organizations and on their employees' behavior is well known. Although not a user-friendly tool, as its impacts may not necessarily be positive, it is becoming increasingly apparent that there is a tendency to apply this tool. Private non-profit organizations are increasingly important in Portuguese society. Currently, there is a concern with social development, environmental conservation, the defense of human rights, among other causes that, for various reasons, generate needs to which the State is unable to respond. Known as Third Sector organizations, also known as the nonprofit sector or the social economy, they act by promoting initiatives and programs to meet the needs of communities. Not having profit as their main objective, these organizations need to generate internal and external results (for the community), which may be obtained, for example, through good strategic management, where human resources play a fundamental role. It is in the intangibility of human resources that the added value of the non-profit sector lies, promoting effective and objective responses to the countless social problems. Thus, the Third Sector, due to its specificities (organization, clients, financing, structure and human resources), requires motivated and committed employees. And it is in this sense that the present work was developed, with the purpose of analyzing the motivation of employees of Non-Profit Organizations, in particular the Private Social Solidarity Institutions in the municipality of Trofa - with and without performance evaluation practices.
Risco e percepção: o caso de Bom Jardim e o “Mega desastre da Região serrana do Rio de Janeiro” em 2011
Authors: Sampaio Andréa Carmo , Costa Gabrielle dos Santos
Published: June 2023

Natural disasters occur around all the world. In Brazil, mass movements and floods are the most frequent, dramatically affecting the populations subject to them. As urbanization advances in risk areas, understanding the processes that trigger these phenomena, as well as understanding the perception of people who are exposed to them, become increasingly important to prevent or reduce their effects. This work points to the urgency that should be given to studies on the vulnerability that populations are exposed staying in risky places, and the understanding of the reasons for this exposure. It assumes that risk does not exist only when there is susceptibility to the occurrence of the phenomenon of “nature” but involves how society can be affected by it and, consequently, a certain vulnerability that is characteristic of this society. The municipality of Bom Jardim, in the state of Rio de Janeiro, was drastically affected by what was recognized as the “Mega Disaster of the Mountain Region”; when intense rains led to the decree of “state of calamity” due to the number and severity of landslides and floods, with incalculable human and economic losses. The magnitude of the event motivated the analysis of the behavior of affected residents who remained living in the same places. It focused to understand vulnerability based on perception, understanding it as a condition in which a society is exposed to the possibility of a harmful event, which can be evaluated by the way they perceive their environment, and the degree of awareness about the risk to which they are exposed. Located in Bom Jardim, the Jardim Ornellas neighborhood is in a context in which the potential for landslides and floods is recognized by the occurrences already registered, having been hardind hit in 2011. It was found that the affected residents stayed in their homes (or returned), putting itself at risk again. It was evident that affection and connection with the place were among the main reasons for this attitude. The diagnosis was obtained through interviews, noting that respondents recognize the risk, but prefer to ignore it, understanding that it is more advantageous to remain. It was concluded that understanding and working on this perception and connection with the place is relevant for planning and promoting awareness and effective and cooperative attitudes among the various actors (society and government sectors).
Rota turística e cervejeira do Rio de Janeiro (Brasil): leitura geoeconômica de um fenômeno produtivo-espacial
Authors: Oliveira Leandro Dias de
Published: June 2023

Brazil is in fact a powerhouse in the manufacture of beers, producing around 15 billion liters per year, a number only surpassed by China and the United States. In addition to the giants in the sector, more than six hundred breweries are registered in Brazil. In 2017 alone, 91 new brewing establishment registrations were granted. With regard to the Rio de Janeiro economy, the phenomenon is similar, with a 900% growth in the number of brewers in the state of Rio de Janeiro. Thus, in recent years, we have seen significant changes in beer production and consumption in the Brazilian and Rio de Janeiro realities. The creation of AmBev has created a giant international company, as well as the significant growth of small artisinal breweries dedicated to the manufacture of a more sophisticated beer for a specific public. In this scenario, the Rota Turística e Cervejeira do Rio de Janeiro (Touristic and Beer Route of Rio de Janeiro) is formed, located in the Serrana Fluminense region and which brings together large and small producers of the drink, more than 60 styles of beer and offers packages that include attractions such as "beer experiences" in the large and microbreweries, visits to tourist attractions in the cities, harmonized tastings in local restaurants. The central objective of this chapter is to understand the productive, urban and touristic changes of this emerging economic-spatial structure from the analysis of the Touristic and Beer Route of Rio de Janeiro, from the Economic Geography and with the scope to analyze the central contents of this new phenomenon economic-tourism.

Unmanned robots being remotely controlled or autonomous are spread worldwide and used in different purposes. Inhabited robots are brought very close to users and accessibility to these tools is very high, moreover, at very low costs. Regardless to emphasize the increasing popularity of these robots. However, any robot system being electrically driven and controlled has bottleneck in the amount of the electrical energy stored aboard in the battery packs. In other words, due to limited amount of the electrical energy available special issues related to use energy best way with maximum effectiveness are needed and considered. Additionally, the battery management system is needed to control the processes of the discharge and the charge ensuring technical data and parameters set by the manufacturer. This paper addresses robot applications in regions out of the calculated when special environmental testing is needed to confirm battery pack technical data. Among those of the environmental tests required the temperature test is in the focus of attention. The main idea and purpose of this paper is to set up new concept of the low-cost environmental temperature test chamber, to define its technical parameters and other properties needed for its preliminary design and prototype manufacturing.

The Dunning-Kruger effect (DKE) in higher education evaluation is one of the current research areas of psychology, educational science, and management science (in our case). Its importance is that the less prepared one is, the less accurately one can judge what performance is expected of him. What is more, he will err more and will overestimate himself. The present study aims better to understand the phenomenon with new, small-sample empirical results. The study is part of a research series that has been ongoing at the University of Debrecen since 2015. It not only quantitatively expands the literature but also includes the course of Knowledge Management among those examined. During the research, students were asked both before the examination (N = 63) and after the examination (N = 76) to guess how many points they would achieve on a multiple-choice test. It supports the presence of DKE, both in the case of pre-examination and post-examination self-evaluations. Using four multivariate linear regression models, we examined whether the sign value or absolute value of the errors made during the guesses show a correlation - in addition to the available control variables - with the test score. Our results showed that the more accurate the pre-examination and post-examination estimations were, the higher the students' actual score was, while the less they tended to overestimate their preparation. This supports the presence of DKE, both in the case of pre-exam and post-exam self-evaluation.

Napjainkban a digitalizáció térhódítása folyamatosan nő. A jelenlegi felnövekvő generáció már „digitális bennszülött”. A digitalizáció részeként feltétlenül említést kell tennünk az internetről, ami kiemelt szerepet tölt be mindennapi életünkben. Az interneten keresünk információt, kommunikálunk, vásárolunk. Ezen tényezők és a 2020-ban kialakult pandémia miatt az internetes ügyintézés is kiemelt fontosságúvá vált. A bankoknak folyamatosan alkalmazkodniuk kell a megnövekedett igényekhez, amik a kényelmes, otthoni bankolást segítik elő. Kutatásunk során éppen erre a folyamatos alkalmazkodásra, és az ebből eredő fejlesztésekre koncentráltunk. A kutatás középpontjában a hazai nagybankok internet- és mobilbankjai álltak. A mintavételezés 2 időszakban zajlott. A primer kutatási eszközök közül a dokumentumelemzést és a netnográfiát választottuk. A kutatás során összehasonlítottuk a platformokon elérhető funkciókat, a mobilbankok fogyasztói megítélését és más változókat. A kutatás során kapott eredmények alapján megállapítható, hogy a hazai bankok folyamatosan fejlesztik az applikációjukat különböző trendek mentén, és igyekeznek igazodni a változó igényekhez. A legtöbb nagybank mobilbankjában komoly változásokat kellett megvalósítani, akár korábbi mobilbankjuk végleges kivezetésével. A változások erős hatást gyakorolhatnak a fogyasztókra, akikből ezen változások gyakran inkább negatív véleményt váltottak ki. Összességében a digitalizálódás ilyetén formája kiemelten fontos ezen szektorban is.  A tanulmány a Tudományos Diákköri Konferenciára készült pályamunka részleteit tartalmazza.
Application of Topological Methods in the Development of Vehicle Components

Published: June 2023

Many areas of the industry are characterized by continuous changes, which define new directions of development in product design. The development of computers and software, the spread of modern production tools and the development of material technology make it possible to expand traditional production technologies with modern processes. Integrated CAD systems have occupied their place in the product design and development process for decades, reforming classical design methods. Popular optimization procedures in integrated CAD systems, such as shape optimization, topological optimization and the new generative design process, provide effective solutions for design engineers in more and more industrial application areas. Experience shows that modern design methods can be used in many areas of industry. The appearance of metal powder printing and additive technology make it possible to test the designed prototypes or even to produce the final products. The following article aims to support the above with the help of a case study.

This research contributes to describing the effect of literacy and numeracy learning on social studies subjects in schools and looks at how it affects 21st-century skills. This research was conducted at SMP Negeri 2 Cikupa. Based on existing theories, it is known that this research hypothesizes that learning literacy and numeracy in social studies subjects can develop students' 21st-century skills. This study used a population of all SMP Negeri 2 Cikupa, which amounted to 1165 students in grades 7, 8, and 9. The samples used just two classes of 9G and 9H classes. The sample was selected through simple random sampling because the population is included in the homogeneous category. The method used is quantitative, with the independent variable X1 literacy, X2 numeracy, and the dependent variable Y1 21st century skills. The data analysis technique was carried out by dividing the research subjects into the experimental and control classes, each being tested with a pretest, posttest, data prerequisites, hypothesis testing T, F, and determinant coefficients. This study concludes that the literacy variable, numeracy, influences 21st-century skills, as evidenced by the results of the literacy T-test on 21st-century skills, which shows that t count 4.676 t table 2.042 and sig. 0.000 0.05 and numeration on 21st century skills t count 3,527 t table 2.042 and sig. 0.001 0.05.
