Analyzing the Relationship between Population Aging and Regional Economic Development in China: Evidence from R-Studio Big Data
Authors: Sun Ruihanyu , Jin Tiema
Published: August 2023

This paper examines the relationship between population aging and
regional economic development in major cities in China by analyzing
R-studio big data. Through correlation analysis, the study finds that
for every percentage point increase in the proportion of elderly people
in a jurisdiction, the city’s economic growth rate falls by 10 percent,
indicating a negative correlation between population aging and economic
growth. The paper attributes the fundamental cause of population aging
to the development of modern science and technology, particularly in the
field of medical and health care. The improvement of people’s health and
extended lifespan, along with the rapid development of the economy and
improvements in living standards, has resulted in a shift in attitudes
towards childbirth, leading to a decrease in birth rates. The research
then constructs a regional economic development model, population growth
trend, and population aging trend chart using cluster analysis and big
data R-studio algorithm. The study takes the fluctuations of residents’
living consumption level and the degree of population aging in a certain
region since 2010 as variables to study the relationship between the
degree of population aging and regional economic development. The
findings of this research contribute to the development of policies and
strategies for sustainable economic growth in the face of population
aging. The paper highlights the importance of exploring solutions to
population aging and promoting economic development.
Numeration of bacteria in water using a sensitive fluorescence spectrometer
Authors: Dai Licheng , Chen Yi , Zhang Fei , Zhao Tianqi , Jin Shangzhong
Published: August 2023

The monitor of pathogenic microorganisms in water is important for
public health and disease outbreaks prediction. Recently, the optical
detection techniques have drawn much attention due to the advantages of
rapid response, security and high sensitivity. In this paper, a
fluorescence spectrometer based on 375 nm exciting laser and the
microchannel liquid sample flow technology is proposed. The 4×4
narrowband filter array was used as a spectroscopic system for high
fluorescence flux, which was coupled to a Silicon Photomultiplier (SiPM)
array with single-photon sensitivity. B500 fluorescent microspheres and
Escherichia coli were used for performance evaluation of the
spectrometer. As a result, it is feasible to use random particle
counting method to detect the bacteria concentration level in water even
low to a single CFU/mL. In addition, the method was successfully applied
to tap water samples. The results suggest that the proposed method is
applicable for on-site bacteria detection.
An introduction to scanning transmission electron microscopy for parasitology samples
Authors: Trépout Sylvain , Sgarra Marie-Laure , Marco Sergio , Ramm Georg
Published: August 2023

Since its inception in the 1930’s, transmission electron microscopy
(TEM) has been a powerful method to explore the cellular structure of
parasites. TEM usually requires samples of < 100 nm thick and
with parasites being larger than 1 µm, their study requires resin
embedding and ultrathin sectioning. During the past decade, several new
methods have been developed to improve, facilitate and speed-up the
structural characterisation of biological samples, offering new imaging
modalities for parasitology. In particular, scanning transmission
electron microscopy (STEM) can be used to observe sample sections as
thick as 1 µm thus becoming an alternative to conventional TEM. STEM can
also be performed under cryogenic conditions in combination with
cryo-electron tomography providing access to the study of thicker
samples in their native hydrated states in 3D. This method, called
cryo-scanning transmission electron tomography (cryo-STET), was first
developed in 2014. This review presents the basic concepts and benefits
of the STEM methods and provides examples to illustrate the potential
for new insights into the structure and ultrastructure of parasites.
Effect of Mixed Manure on Selected Chemical Properties, and Phosphorus Adsorption Characteristics of Vertisols in Haramaya District, Eastern Ethiopia
Authors: Gutema Dejene , Kibret Kibebew , Dechasa Nigussie , Mirkena Lemma
Published: August 2023

The high phosphorus fixing characteristics of Vertisols and the lack of
crop response to its application as a fertilizer is one of the major
challenges leading to phosphorus deficiency. Its bioavailability is
determined by adsorption and desorption characteristics. A Pot
experiment was conducted to investigate the effect of mixed manure on
phosphorus adsorption characteristics using the batch equilibrium method
including selected properties of Vertisols. Four rates of mixed manure
(0, 5, 10, and 15 t ha ) were added to the soil.
Following 30 days incubation period, changes in selected soil
properties, phosphorus adsorption, and desorption characteristics were
studied. The data were analyzed using ANOVA. The results revealed a
significant decrease in soil pH, and increase in soil organic carbon,
total nitrogen, available phosphorus, and cation exchange capacity as
compared to the control. The overall means of the amount and efficiency
of adsorbed phosphorus were significantly decreased due to mixed manure.
Besides, the interaction effect of mixed manure and added phosphorus
concentration revealed a significant increase in both the amount and
efficiency of adsorbed phosphorus. Both parameters revealed an
increasing trend with increased rates of added phosphorus concentration
but decreased with increased rates of mixed manure. Though all
treatments were fitted well to both the Freundlich and Langmuir
isotherms, the former one was used to due to its higher R
value. Freundlich adsorption coefficient and
intensity were found reduced significantly compared to the control.
Therefore, mixed manure application has increased phosphorus
availability by reducing its adsorption and related properties of
Vertisols.
Influence of laser fluence and pulse duration on patterning of perovskite solar cells: An analysis of optoelectronic and electrical parameters by hyperspectral photoluminescence imaging

Published: August 2023

Up-scaling of perovskite solar cells and modules requires both the
development of suitable laser patterning processes for series
interconnection of the cells and the quantification of the spatial
distribution of solar cell parameters. Here, we investigate perovskite
solar cells patterned with ns and ps laser pulses at varying laser
fluences and analyze them with hyperspectral photoluminescence (PL)
imaging. Based on these images, mappings of the distribution of the
central PL wavelength, the quasi-Fermi-level splitting, the Urbach
energy and the shunt resistance were calculated. From the behavior of
these parameters, particularly in the vicinity of the laser trenches, we
infer laser-material interaction processes and their influence on the
electrical performance of the interconnected cells. It is shown that
both ps and ns laser pulses can be used for successful series
interconnection with low electrical losses in a very narrow edge
regions, provided that the fluence is carefully adjusted.
Numerical investigation on free cooling performance of ground-source heat pump in a solar greenhouse
Authors: Hou Zhao , Hu Yuqiu , Liu Xiaojie , Wang Jianhua , Yang Mei , Fan Jun
Published: August 2023

This paper presents the numerical study of a ground source heat pump with borehole free cooling in a solar greenhouse. The system is mainly composed of a solar greenhouse with a water-water heat pump, a ground heat exchanger, and several pipes for free cooling. Thermal performances of ground source heat pump with and without borehole free cooling are investigated. The cooling time of the solar greenhouse is divided into transitional seasons (May and September) and summer seasons (from June to August). The mixed mode, including the free cooling mode and the ground source heat pump cooling mode, runs in summer seasons. During the entire transition seasons, the free cooling mode consumes 33.6% of the electricity in the ground source heat pump cooling mode and the soil thermal storage in free cooling mode is 76.3% of that in ground source heat pump cooling mode. Throughout the summer seasons, the power consumption of the mixed mode is 4.3% lower than that of the ground source heat pump cooling mode, and mixed mode soil thermal storage is 19.5% lower than that of ground source heat pump cooling mode. The results indicate that borehole free cooling system has better energy-saving performance during whole cooling period. In addition, a borehole free cooling system can also reduce the thermal imbalance in the soil.
Site-level tool for identifying other effective area-based conservation measures (OECMs)
Authors: Jonas Harry D. , MacKinnon Kathy , Marnewick Daniel , Wood Pete
Published: August 2023

Other effective area-based conservation measures (OECMs) are sites outside protected areas that deliver effective and long-term in situ conservation of biodiversity. Biodiversity conservation may be the primary objective of the site, a secondary objective of a site that is managed for other purposes, or it may be an unintended consequence of the way the site is managed. OECMs may be governed and managed by governments, private entities or Indigenous peoples and local communities, or a combination of these. This tool guides an assessor through three steps to apply eight criteria which determine if a site qualifies as an OECM as set out under the Convention on Biological Diversity. For sites which do not currently meet all the criteria, the tool serves to highlight areas where further information or improvements in governance and management are required.

La mediación en el sistema no jurisdiccional de protección de derechos humanos en México
Authors: Serrano Morán José Antonio , Rosas Topete Nicté
Published: August 2023

El principal objetivo del presente artículo ha sido analizar la forma en la que se conceptualiza y aplica la justicia alternativa, específicamente la figura de la mediación, dentro del sistema no jurisdiccional de protección de derechos humanos en México. El tipo de investigación realizado es esencialmente de corte documental-descriptivo, haciendo uso de los métodos deductivo, discursivo sistemático jurídico, funcionalista dialéctico, analítico-sintético, exegético y método de interpretación jurídica.

Como resultado, se obtuvo que del marco normativo de solo cinco comisiones locales, existe una adecuada conceptualización, delimitación e implementación de las etapas del proceso de mediación. Sin embargo, esto ha llevado a un uso inadecuado de los métodos alternos de solución de conflictos, lo cual ha generado la saturación del proceso de queja como único medio de reacción en materia de protección de derechos humanos de los ciudadanos frente al gobierno. Esto vuelve ineficiente el sistema no jurisdiccional de protección de derechos humanos.

Por lo tanto, se concluye la necesidad de homologar los criterios en materia de justicia alternativa para todas las Comisiones de Derechos Humanos en nuestro país. Esta tarea debe ser asumida por la Federación Mexicana de Organismos Públicos de Derechos Humanos, con el objetivo de proponer la armonización para el sistema no jurisdiccional de protección de derechos humanos en México. Esto implica adaptar los procesos de conciliación y/o mediación a las leyes orgánicas y reglamentos de dichos organismos autónomos, con el fin de respetar las etapas, principios, características y roles que desempeñan las partes en un verdadero proceso autocompositivo.

University students are known to have different sleeping schedules. Students’ sleep difficulties will affect their health and their performances in studies. Sleep hygiene is a collection of healthy sleep habits that can improve one’s ability to fall asleep and stay asleep. It is considered to be imperative to treat sleep disturbance especially among university students. The aim of this study is to examine the sleep beliefs among the students of UiTM Sabah based on gender and academic performance. This study was conducted on Diploma students between March and July 2018. The respondents were randomly selected from Diploma students of all faculties in UiTM Sabah: Accounting, Business Management, Public Administration, Science, Planting Industry Management, Hotel Management, and Tourism Management. This paper is based on the Sleep Belief Scale questionnaire to assess the sleep hygiene awareness. Questionnaires were distributed using online survey. Findings of this study were analyzed using SPSS statistical software. The result of findings showed that the Sleep Incompatible Behaviours (drinking coffee, taking sleep medication, smoking before sleep) is the highest contributor of the students’ sleep hygiene and therefore it affects the sleep quality. While the Sleep Wake Cycle Behaviours(going to bed & waking up always at the same hour, going to bed two hours earlier than the habitual hour) and Thoughts and Attitude to Sleep (over thinking before sleep, trying to fall asleep without having a sleep sensation)also contributed to the sleep hygiene of the students but not as high as the Sleep Incompatible Behaviours. Based on the results of the findings, the counseling department of UiTM Sabah may organise an education program to create awareness among students about the intervention and prevention strategies as well as the incorrect beliefs about sleep.

Leer el ‘desorden’. Cambio agrario, campesinados y el Sembrando Vida
Authors: Cano Castellanos Ingreet Juliet
Published: August 2023

El estudio de las ruralidades contemporáneas tiende a acompañarse de la imagen del campesinado en proceso de desaparecer. Frente a esta tendencia, propongo analizar el panorama actual como el tránsito entre un pasado ‘desordenado’ a un presente ‘desordenado’, y cuestionar la inclinación a pensar los campesinados como lo opuesto al capital y al estado. Basada en el trabajo de campo etnográfico en localidades del sureste chiapaneco, adicionalmente evidencio lo que el programa Sembrando Vida añade a las experiencias rurales. Así entonces, con una perspectiva procesual, reflexiono en torno a clásicas preguntas en los estudios rurales: ¿Quiénes son los campesinos? ¿Asistimos al fin del campesinado en el capitalismo agrario del siglo XXI?

Authors: Muiño Walter , Galmes Maximiliano A. , Del Ponti Omar David
Published: August 2023

La cuenca inferior del río Atuel en la provincia de La Pampa es el escenario de un proceso de desecamiento ocurrido progresivamente desde la instalación de las primeras poblaciones de colonos en la cuenca superior, pero la interrupción definitiva del escurrimiento ocurrió en 1948. A partir de ese año los pobladores asentados en la cuenca inferior sufrieron severas consecuencias que impactaron en su vida y en su cultura, tal como la interacción con los recursos naturales del entorno. La fauna constituye uno de los componentes ecosistémicos que intervienen en la cultura de las sociedades y le dan matices propios. El propósito de este trabajo es registrar los cambios diacrónicos ocurridos en los conocimientos sobre la ictiofauna y la avifauna asociada al río. Por medio de entrevistas abiertas a pobladores ribereños se indagó sobre sus conocimientos relacionados con la ictiofauna y la avifauna del lugar. Se indagó sobre los nombres comunes de peces y aves, así como los aspectos que hacen a la interacción y la percepción de los entrevistados sobre esos componentes del ecosistema. Esas actividades y conocimientos fueron cotejadas con las del pasado, recurriendo a la documentación histórica registrada en el área. La información obtenida establece un nivel de base actual que puede contribuir a facilitar las propuestas de acción que pudieran implementarse en las políticas públicas de desarrollo local.

The communication satisfaction of patients by health care professionals and its implications
Authors: Kipouropoulou Maria , Varsamaki Chrysoula
Published: August 2023

Introduction: The effectiveness of an organization depends on the communication relationships that develop in its environment. The structure of the organization or its design influences the behavior and the performance of the people who work in it. The purpose of this project is to highlight in a clear and comprehensive way the importance of effective communication which is essential to the quality, productivity and competitiveness of a modern organization.
Methodology: “Qualitative research” by statistical analysis was considered appropriate, as through qualitative research dimensions of human behavior, such as perceptions, values, attitudes, beliefs and experiences
of respondents, are investigated and interpreted. The population group from which information about the research project was derived consists of hospitalized patients or hospital health care applicants, with a sample of 140 Likert-scale questionnaires. The SPSS IBM Statistics 24 program was used as a research tool for the statistical analysis of the data.
Conclusions: The communication satisfaction was investigated based on the fact that health is a social good and this, in itself, increases the demands and expectations of the user-recipient of the services provided by
the health care system. The quality in hospitals is not just a matter of a specific process or of a part of the hospital, nor is it connected only to a person’s duties. It is obvious that there are serious communication problems in clinical practice, while the interpersonal skills of health professionals determine the patients’ satisfaction in a large scale.

The Procedure for Accreditation of Medical Laboratories for Compliance with the Requirements of GOST R ISO 15189-2015 «Medical Laboratories. Particular Requirements for Quality and Competence» in the National Accreditation System
Authors: Kornoukhova L. A. , Ivanov A. M. , Belevitin A. B. , Emanuel V. L.
Published: August 2023

Introduction. The laboratory should have a quality management system for laboratory research. The objective was to analyze the requirements of regulatory documentation related to the accreditation of medical laboratories in the National Accreditation System for compliance with GOST R ISO 15189-2015. Methods and materials. A retrospective analysis of the requirements of national and industry standards related to medical laboratories was carried out. Results. The policy management of the activities of the National Accreditation System is based on strict compliance with the requirements of international rules. The provisions of the regulations of the Ministry of Economic Development are a priority for the Federal Accreditation Service. Applicants must comply not only with GOST R ISO 15189-2015, but also with the accreditation criteria of the National Accreditation System. Failure to comply with the requirements related to the traceability of measurement results, measurement uncertainty during calibrations and rules for registration of protocols, entails refusal of accreditation or suspension of its validity. It is mandatory to provide information on the results of activities, including information on issued reports (protocols) with the attachment of an electronic document «in the form of an electronic image (scanned copy) of the document» using the Federal State Information System, about changes in the composition of its employees and their competence, changes in technical equipment in the field of accreditation, about the temporary absence of an employee. Work experience in the field of employee accreditation needs to be documented. Participation in qualification verification programs in the field of accreditation is a criterion of laboratory competence and confirmation of the reliability of measurement results issued by laboratories. It is important to observe strictly defined deadlines for submitting documents to confirm competence. Submitting an application outside of school hours leads to refusal. Conclusion. It is necessary to recommend participation in voluntary accreditation for laboratories conducting research at the interstate level. It is necessary to form a state policy in the field of quality of laboratory diagnostics based on GOST R ISO 15189-2015 and formulate it in the format of a federal law. The formed chain of metrological traceability should include reference, calibration and routine laboratories. It is necessary to introduce changes and clarifications into the regulatory framework of the National Accreditation System, taking into account the peculiarities of medical laboratories.

Introduction. In view of the course of the disease, patients suffering from pancreatic adenocarcinoma go through all stages of medical care in St. Petersburg. To date, in the available literature, there are no works devoted to the analysis of the types, volumes and outcomes of medical interventions performed in this category of patients. The data obtained from such an analysis can become the basis for the development of algorithms and programs for optimizing the provision of care for patients suffering from this pathology. The objective of the study was to analyze the types of medical interventions for patients suffering from pancreatic cancer in hospitals in St. Petersburg for the period from 2014 to 2020. Methods and materials. The study group consisted of a continuous sampling of data from 2414 cards of patients diagnosed with pancreatic adenocarcinoma who applied to medical organizations in St. Petersburg in the period from 2014 to 2020. The provided medical interventions were divided into the following types: radical, symptomatic and palliative treatment. Results. In 69.4 % of patients in the study sample during the initial visit, stage III and IV of the disease were diagnosed. The volumes and methods of treatment differed for different localizations of the tumor node. In patients with a tumor lesion of the head of the pancreas, «symptomatic treatment» was most often used, in patients with localization of the neoplastic process in the body of the pancreas, «diagnostic surgery» was most often performed, in the case of damage to the tail of the pancreas, the main method of treatment was «radical surgery». In federal medical organizations, «symptomatic treatment» was most often performed. In specialized oncological medical organizations of the city, «radical», «symptomatic» and «diagnostic» interventions were performed in the same way. In city multidisciplinary hospitals, «symptomatic treatment» was most often performed. Conclusion. The data obtained should be taken into account when improving and developing new programs for the detection of pancreatic adenocarcinoma at early stages. Further monitoring of medical interventions in this category of patients is required.

Introduction. Bronchial fistula often occurs after lung surgery. This is an extremely severe complication with high mortality. Despite the variety methods for the treatment of bronchial fistula, the results are not always effective. In our paper, we presented a method of preventing the development of bronchial fistula based on the cell therapy. The objective of the study was to evaluate the effects of the cell therapy on the regeneration of damaged bronchial tissue in an experiment on non-human primates. Methods and materials. The study was performed on 6 non-human primates. Laboratory animals were divided into 2 groups: experimental and control. The left pneumonectomy with the formation of a stump of the main bronchus was done in each primate. In the experimental group, a regenerative product was introduced into the stump; in the control group, 0.9 % NaCl solution was used. The regenerative product consisted of autologous platelet-rich plasma activated by thermal lysis and the suspension of the xenogeneic fibroblast’s culture. The primates were observed for 7, 14 and 21 days, the peripheral blood was taken to study the dynamics of biologically active substances. A histological examination of the autopsy material was performed at the end of the follow-up time. Results. On the early postoperative period, a typical inflammatory reaction was observed and resulted by the intraoperative tissue damage. Then the morphological changes were different in both group. The inflammatory were mild, the restoration of the natural function of the mucous membrane and the formation of scar tissue were earlier in the experimental group than in the control group. An analysis of the dynamics of plasma mediators in the postoperative period revealed an earlier dominance of regenerative processes in the experimental group. Conclusion. The results of the study showed that the cell therapy stimulates the tissue regeneration, thereby preventing the failure of the bronchial stump suture.
Psychosocial factors of psychological maladaptation in female patients of a cosmetology clinic
Authors: Bagnenko E. S.
Published: August 2023

Introduction. In the field of aesthetic medicine, there is a lack of psychological research despite the obvious impact of cosmetic defects on the emotional state and social functioning of a person. Only a few studies indicate psychological maladaptation in patients of a cosmetology clinic, which is reflected in the frequency of the occurrence of anxiety, depression and personality disorders exceeding their levels in population. The objective was to identify psychosocial factors associated with the risk of psychological maladaptation in female patients of the cosmetology clinic. Methods and materials. To achieve the goal, female patients (n=161, mean age was 39.53±0.86 years) were studied using the author’s structured interview and 7 psychodiagnostic methods: «Neuropsychic Adaptation Test» (NPA), «Social Frustration Level» (SFL), «Visual Analogue Self-Esteem Scale» (VASES), «Semantic Time Differential» (STD), «Perceived Stress Scale» (PSS-10), «Well-Being Index» (WHO-5), «Quality of Life Satisfaction Questionnaire» (QOL). Groups of female patients without psychological maladaptation (group 1, n=74) and those with psychological maladaptation (group 2, n=87), selected on the basis of the final NPA test score were compared. Results. The results showed a statistically significant predominance in group 2 compared to group 1 of the frequency of emotionally neutral relationships with their own children, of living alone, as well as dissatisfaction in significant areas of life, especially in the material economic sphere, in the sphere of self-accepting as a personality and one’s physical «Ego», in the sphere of attitude to past and present life. In group 2, higher rates of perceived stress and frequency of psychotraumatic situations in anamnesis as well as lower rates of general psychological well-being and satisfaction with the quality of life were revealed. Conclusion. The factors influencing the psychological maladaptation in female patients of the cosmetology clinic were identified. The prospects of the study associated with the determination of the most informative factors for the prognosis of psychological adaptation based on the analysis on not only psychological but also individual and personal characteristics in female patients of the cosmetology clinic were indicated.

Published: August 2023

The Eylul Revolution in the Kurdish areas of Iraq represents a milestone in the history of the Kurdish national liberation movements. Apart from its intensity and wideness, this revolution enjoyed massive popular support from a wide array of forces in the Kurdish parts of Iraq. The Revolution furthermore also can be said to represent the first Kurdish armed movement that prioritized building foreign relations for the achievement of several interconnected foreign policy goals. After 60 years, some of those early relations or practices that emerged in those early days still impact the Kurdish foreign relations or the conduct of foreign policy by the current Kurdish de facto entity.

This project aimed at creating and implementing a web-based portal that allows students of the university of soran to be able to commence and complete the annual process of course clearance online instead of physically navigating sections offices. The student clearance system is an internet-based study initiative that will help facilitate the queuing system in the clearance process of the university. The student clearance system can provide an efficient handling of information that is very easy for universities to use since it is internet-based and can be viewed from anywhere and at any time, and this system or process is also performed every year at the end of the second Semester by students. Students at Soran University in all scientific departments can register through this web application and do end-of-year cleaning work at the university. In this way, we will avoid using paper and loss, and the creation of student crowds at the doors of departments. and facilitating students to do so via the Internet. The computer-based architecture in this project was introduced using the PHP language, JavaScript, CSS, HTML and the software database as MySQL. The program created would act as a more effective and productive way of clearing students, eliminating all types of delay and tension, as well as helping you to understand the process involved, as well as how to do your online clearance. This research work uses the compilation of data from the university, materials and the program has been designed to accomplish the project objective efficiently.

Understanding Chinese International Students' Struggle in Canadian University during COVID-19: A Literature Review
Authors: Liu Chunlei
Published: August 2023

The economic impact of international students in Canada is tremendous. As the enrollment of domestic students has decreased, the admission of overseas students has made up for the financial losses that Canadian institutions suffer due to the drop in domestic student enrollment. China is a significant exporter of international students to Canada, sending a sizable number of them there yearly. Chinese international students' entrance to Canadian universities is being impacted by the COVID-19 pandemic. This article contends that because of their temporary immigration status, international students in Canada are at risk. It does this by drawing on the literature analysis approach. They are not included in the majority of government assistance initiatives intended to assist Canadians during this outbreak. The majority of overseas students struggle financially and psychologically as a result of the pandemic. The circumstance is causing a further drop in the admittance of international students, with economic repercussions for Canadian institutions. The report advances our knowledge of the struggles faced by international students and educational institutions during the COVID-19 pandemic by examining the issues they face as well as the methods needed to increase their resilience and universities' capacity.

Published: August 2023

Uma das maiores dificuldades encontradas em sala de aula pelos professores está relacionada com a prática pedagógica inclusiva, para atender os alunos que apresentam alguma deficiência. Nessa perspectiva, o objetivo deste estudo foi de aplicar uma ferramenta educacional denominada “Quiz Periódico”, para avaliar os conhecimentos prévios dos alunos sobre a “Tabela Periódica”. O instrumento foi aplicado com duas turmas do terceiro ano do ensino médio, da Escola Estadual Cleinia Rosalina de Sousa, localizada no município de Cuiabá-MT. Foi utilizado o método qualitativo com a abordagem da pesquisa-ação, ancorada pela Peer Instructions, metodologia ativa de aprendizagem, onde os alunos auxiliam uns aos outros nos entendimentos dos conceitos, e em seguida, são conduzidos pelo professor no aperfeiçoamento desse aprendizado por meio de questões dirigidas. As análises da pesquisa mostraram que a proposta didática realizada envolvendo o levantamento das concepções prévias através da ferramenta, auxiliou na elaboração conceitual dos estudantes que participaram ativamente do processo, possibilitando uma melhor compreensão do conteúdo abordado. Os resultados demonstraram que através desta prática foi possível identificar uma proposta interdisciplinar e de inclusão, envolvendo os alunos na atividade, aproximando-os com o conteúdo abordado. Concluímos também que através do Braille, instrumento de escrita e leitura utilizado neste jogo, é possível que ocorra a aprendizagem do aluno deficiente visual. E, por último, o mais importante é que através do trabalho em equipe e da interação dos alunos ocorreu o respeito mútuo e a empatia, potencializando assim o ensino inclusivo.

Published: August 2023

Studies of preview gust load alleviation [Formula: see text] and [Formula: see text] controllers via synthesis, simulation, wind tunnel tests, and test/simulation correlation are presented in this paper. University of Washington active aeroservoelastic wind tunnel model design, construction, and testing capabilities are used. The test article is a flexible half wing–body–tail model with active control surfaces of two ailerons and an elevator. The model moves in a combination of rigid-body and elastic motions. The commands of gust vanes are used both to generate gusts and to provide real-time preview gust encounter information. A discrete-time linear-time-invariant output feedback system is augmented with various preview lengths of information. The experimental results show that gust loads are reduced with gust preview information compared to feedback-only control and are halved with the fullest gust preview information compared to the open-loop case. The wind tunnel results validated the simulations and added insights to the performance of preview [Formula: see text] and [Formula: see text] control implementation. The closed-loop analysis quantified the margins and robustness of the systems and correlated with the time history of both simulations and experiments. This paper presents preview gust load alleviation robust control test results, not available so far, in a realistic experimental setting.

Published: August 2023

The nonlinear dynamic behaviors of dual-rotor-bearing systems with looseness and rub–impact faults are discussed in this paper. The dual-rotor-bearing system with looseness and rub–impact coupling faults is established by the finite element method. The component mode synthesis (CMS) and proper orthogonal decomposition (POD) methods are introduced. The CMS and POD methods are used to reduce the original rotor system model, and the efficiency of the order reduction method is verified by comparing the dynamic behaviors of the original and reduced systems. The frequency spectrum and amplitude–frequency behaviors of rotor systems are studied. The results can provide qualitative guidance to structural design optimization of large rotating machines and prior information for looseness and rub–impact coupling faults.
Employee Monitoring: As Technology Advances Yet the Electronic Communications Privacy Act Stays in the Past
Authors: Possino Isabella
Published: August 2023

Since the Electronic Communications Privacy Act of 1986 was enacted, the United States has endured an evolution of technology. While progressive at its inception, the ECPA has since been met with a tumultuous response from scholars, courts, and others trying to understand its purpose and application regarding privacy rights and the monitoring of communications. Specifically, since the COVID-19 pandemic, the ECPA has remained at the forefront of debate with respect to employee monitoring and surveillance practices. This article provides an overview of the ECPA and explains why today’s technological advancements have surpassed the protections afforded by the Act, leaving employees at risk and employers with significant discretion to implement their desired monitoring practices. While initially intended to extend privacy protections for U.S. citizens, the Act carved out various exceptions for which monitoring is permitted, including most business-related purposes. In addition, this article discusses the approaches and legislation that several states have proposed to combat the ambiguities of the ECPA and highlights the various ways the federal government could amend the ECPA to resolve such challenges and protect the privacy rights of employees in U.S. companies.
