Gaussian Decomposition vs. Semiclassical Quantum Simulation: Obtaining the High-Order Derivatives of a Spectrum in the Case of Photosynthetic Pigment Optical Properties Studying
Authors: Razjivin Andrei P. , Kozlovsky Vladimir S. , Ashikhmin Aleksandr A. , Pishchalnikov Roman Y.
Published: October 2023

In this paper, a procedure for obtaining undistorted high derivatives (up to the eighth order) of the optical absorption spectra of biomolecule pigments has been developed. To assess the effectiveness of the procedure, the theoretical spectra of bacteriochlorophyll a, chlorophyll a, spheroidene, and spheroidenone were simulated by fitting the experimental spectra using the differential evolution algorithm. The experimental spectra were also approximated using sets of Gaussians to calculate the model absorption spectra. Theoretical and model spectra can be differentiated without smoothing (high-frequency noise filtering) to obtain high derivatives. Superimposition of the noise track on the model spectra allows us to obtain test spectra similar to the experimental ones. Comparison of the high derivatives of the model spectra with those of the test spectra allows us to find the optimal parameters of the filter, the application of which leads to minimal differences between the high derivatives of the model and test spectra. For all four studied pigments, it was shown that smoothing the experimental spectra with optimal filters makes it possible to obtain the eighth derivatives of the experimental spectra, which were close to the eighth derivatives of their theoretical spectra.

Published: October 2023

Laser gas sensors with small volume and light weight are in high demand in the aerospace industry. To address this, a coin-sized oxygen (O2) sensor has been successfully developed based on a small toroidal absorption cell design. The absorption cell integrates a vertical-cavity surface-emitting laser (VCSEL) and photodetector into a compact unit, measuring 90 × 40 × 20 mm and weighing 75.16 g. Tunable diode laser absorption spectroscopy (TDLAS) is used to obtain the O2 spectral line at 763 nm. For further improving the sensitivity and robustness of the sensor, wavelength modulation spectroscopy (WMS) is utilized for the measurement. The obtained linear correlation coefficient is 0.9994. Based on Allen variance analysis, the sensor achieves an impressive minimum detection limit of 0.06% for oxygen concentration at an integration time of 318 s. The pressure-dependent relationship has been validated by accounting for the pressure factor in data processing. To affirm its efficacy, the laser spectrometer underwent continuous atmospheric O2 measurement for 24 h, showcasing its stability and robustness. This development introduces a continuous online laser spectral sensor with potential applications in manned spaceflight scenarios.
Detecting Risky Authentication Using the OpenID Connect Token Exchange Time
Authors: Han Alex Heunhe , Lee Dong Hoon
Published: October 2023

With the rise in sophisticated cyber threats, traditional authentication methods are no longer sufficient. Risk-based authentication (RBA) plays a critical role in the context of the zero trust framework—a paradigm shift that assumes no trust within or outside the network. This research introduces a novel proposal as its core: utilization of the time required by OpenID Connect (OIDC) token exchanges as a new RBA feature. This innovative approach enables the detection of tunneled connections without any intervention from the user’s browser or device. By analyzing the duration of OIDC token exchanges, the system can identify any irregularities that may signify unauthorized access attempts. This approach not only improves upon existing RBA frameworks but is also in alignment with the broader movement toward intelligent and responsive security systems.
Do Size and Ownership Determine the Willingness for Sustainable Innovations in Spa and Health Tourism? A Case Study on Baile Felix Spa Resort, Romania
Authors: Trip Diana-Teodora , Simut Ramona , Badulescu Daniel
Published: October 2023

There is a considerable debate in the literature regarding the real impact of tourism on the environment and human communities, specifically with respect to tourism’s openness to sustainable innovation. The way in which the different forms of tourism and entrepreneurial and managerial initiatives respond to the new economic, technological, social and environmental challenges acquire considerable importance for academics, practitioners, decision makers and consumers. The purpose of this research is to assess the potential for sustainable innovation in spa and health tourism in a relevant area in Romania through a survey-based study of both entrepreneurs who own a tourist accommodation unit, as well as top and middle managers from large tourism enterprises. The results of our research show that the development of spa and health tourism offers multiple examples of good practices, and that stimulating innovative entrepreneurial initiatives can lead to a sustainable reinvention of the tourism and local economy, in line with the international health tourism market. In the case of small businesses, even though sustainable initiatives are present, they are at an earlier stage and are less diversified compared to hotels, the scope of innovation is smaller and their motivation weaker. In other words, a large part of the objectives of modernization and sustainability in spa and health tourism (equipment, services, qualification and hiring of employees, sustainable and environmentally friendly orientation) are the responsibility of large hotel resorts. This research provides valuable insights into the ongoing debate surrounding the impact of tourism on the environment and local communities, with a specific focus on the potential for sustainable innovation in spa and health tourism within a significant region of Romania.
The Effect of Color Saturation of Travel Pictures on Consumer Appeal
Authors: Lin Li , Chen Yuting , Zhu Hong , You Jiwang
Published: October 2023

In the Internet era, online channels have contributed significantly to tourism marketing and promotion. Consumers will receive tourism information online to reduce information asymmetry. Moreover, with overwhelming levels of information, consumers may only get a limited amount of information. Therefore, the primary concern for marketers lies in capturing consumers’ attention during this stage. Visual design is essential among the various factors researchers have thoroughly investigated. Studies have recognized the importance of the color characteristics of travel photos on consumer decisions. However, these studies often focus their analysis on tonal information while neglecting the intuitive emotional impact of color saturation on consumers. Consequently, this study aims to distinguish and categorize different tourist destinations to explore the impact of saturation characteristics of attraction photos on consumer appeal in online scenarios. This study contributes to existing knowledge of color context theory, enhancing its contextual application. The findings presented in this paper have implications for developing more effective visual marketing strategies.
Enthalpy of Formation of the Nitrogen-Rich Salt Guanidinium 5,5′-Azotetrazolate (GZT) and a Simple Approach for Estimating the Enthalpy of Formation of Energetic C, H, N, O Salts

Published: October 2023

The discrepancy between the calculated (CBS-4M/Jenkins) and experimentally determined enthalpies of formation recently reported for the 2:1 salt TKX-50 raised the important question of whether the enthalpies of formation of other 2:1 C, H, N, O salts calculated using the CBS-4M/Jenkins method are reliable values. The standard (p° = 0.1 MPa) enthalpy of formation of crystalline guanidinium 5,5′-azotetrazolate (GZT) (453.6 ± 3.2 kJ/mol) was determined experimentally using static-bomb combustion calorimetry and was found to be in good agreement with the literature’s values. However, using the CBS-4M/Jenkins method, the calculated enthalpy of formation of GZT was again in poor agreement with the experimentally determined value. The method we used recently to calculate the enthalpy of formation of TKX-50, based on the calculation of the heat of formation of the salt and of the corresponding neutral adduct, was then applied to GZT and provided excellent agreement with the experimentally determined value. Finally, in order to validate the findings, this method was also applied to predict the enthalpy of formation of a range of 1:1 and 2:1 salts (M+X− and (M+)2X2− salts, respectively), and the values obtained were comparable to experimentally determined values. The agreement using this approach was generally very good for both 1:1 and 2:1 salts; therefore, this approach provides a simple and reliable method which can be applied to calculate the enthalpy of formation of energetic C, H, N, O salts with much greater accuracy than the current, commonly used method.

Triazole fungicides are widely used in the world, mainly in agriculture, but their abuse and possible toxic effects are being reported in some in vivo and in vitro studies that have demonstrated their danger to human health. This in vitro study evaluated the cytotoxicity, oxidative stress and proinflammation of EA.hy926 endothelial cells in response to ipconazole exposure. Using the MTT assay, ipconazole was found to produce a dose-dependent reduction (*** p < 0.001; concentrations of 20, 50 and 100 µM) of cell viability in EA.hy926 with an IC50 of 29 µM. Also, ipconazole induced a significant increase in ROS generation (** p < 0.01), caspase 3/7 (** p < 0.01), cell death (BAX, APAF1, BNIP3, CASP3 and AKT1) and proinflammatory (NLRP3, CASP1, IL1β, NFκB, IL6 and TNFα) biomarkers, as well as a reduction in antioxidant (NRF2 and GPx) biomarkers. These results demonstrated that oxidative stress, proinflammatory activity and cell death could be responsible for the cytotoxic effect produced by the fungicide ipconazole, such that this triazole compound should be considered as a possible risk factor in the development of alterations in cellular homeostasis.
Judgments of Event Centrality as Predictors of Post-Traumatic Growth and Post-Traumatic Stress after Infidelity: The Moderating Effect of Relationship Form
Authors: Jules Bridget N. , O’Connor Victoria L. , Langhinrichsen-Rohling Jennifer
Published: October 2023

Infidelity, a betrayal within a romantic partnership, often violates a person’s core beliefs about themselves and their significant other and can influence the degree to which a person can feel safe in romantic relationships. Infidelity can also increase exposure to sexually transmitted diseases that can compromise physical and mental health. Therefore, infidelity can be judged as central to one’s identity and potentially traumatic, possibly triggering outcomes similar to other DSM-5 Criterion A traumas. The current research examines the contribution of centrality perceptions to the development of PTG and PTS post-infidelity. Bivariate regressions examined the relationships between the judged centrality of infidelity and PTG and PTS, respectively. Exploratory analyses considered the moderating role of relationship form (i.e., casually dating, exclusively dating, and engaged/married) on those relationships. In a sample of 177 adults, greater judgments of the centrality of infidelity were associated with both PTG and PTS. Results demonstrated a significant moderating effect of relationship form on the relationship between the centrality of infidelity and PTG but not between the centrality of infidelity and PTS. Moderation results demonstrated that if infidelity is considered central in a casually dating relationship, it is more strongly related to PTG than in other relationship forms. Considering infidelity as central may generate both beneficial and problematic post-traumatic outcomes. However, an early infidelity experience may provide increased opportunities for engagement in different behaviors in the future (e.g., selecting a different partner, setting different relational boundaries), which, in turn, may be more conducive to growth.

Published: October 2023

We investigated the clinical–epidemiological profile and outcomes of COVID-19 patients hospitalized in 2022, during the Omicron variant/subvariant prevalence, in different Brazilian regions to identify the most vulnerable subgroups requiring special attention. Data from COVID-19 patients were extracted from the national Information System for Epidemiological Surveillance of Influenza (SIVEP-Gripe database), and analyses stratified by region and age group were conducted. The constructed dataset encompassed clinical–epidemiological information, intensive care unit admission, invasive and non-invasive ventilation requirements, vaccination status, and evolution (cure or death). It was observed that there were significant differences in the vaccination rates between regions, in the occurrence of unfavorable outcomes, and in the pattern of comorbidities in young patients. The north region had higher rates of unvaccinated patients and a lower percentage of those vaccinated with three doses in all age groups compared to other regions. The northeast region had the highest rates of patients admitted to the ICU for all age groups, while the north and northeast were the most affected by IMV requirements and in-hospital death in all age groups. This study showed that extended vaccination coverage, especially booster doses, can protect different population segments from developing severe disease since lower vaccination coverage was observed in regions with higher fatality rates.

Authors: Zhang Tian-Ye , Di Dong-Rui , Liao Xing-Liang , Shi Wei-Yu
Published: October 2023

Forests, being the primary repository of terrestrial biodiversity, possess a significant capacity to regulate the phenomenon of climate change. It is additionally crucial to consider how natural disasters affect the state and development of forest biodiversity. The alteration of climate patterns over recent decades has had a discernible impact on forest ecosystems, specifically the damage caused by drought to ecosystems, has become increasingly evident. Nevertheless, there is limited research to elucidate the relationship between forest biodiversity and drought, as well as to explore the mechanisms of biodiversity response to drought. This review synthesizes the existing literature on the effects of climate change on forests across various scales and examines the adaptive responses of forest communities to drought-induced stress. Forest biodiversity can be influenced by various factors, including the severity of drought, initial climatic conditions, and the composition of species in drylands. During periods of drought, the biodiversity of forests is influenced by a range of intricate physiological and ecological factors, encompassing the capacity of plants to withstand drought conditions and their subsequent ability to recuperate following such periods. Moreover, the choice of different drought indices and biodiversity estimation methods has implications for subsequent response studies.
Cell Design Considerations and Impact on Energy Density—A Practical Approach to EV Cell Design
Authors: Yourey William
Published: October 2023

Higher-energy-density, Wh L−1 or Wh kg−1, lithium-ion cells are one of the critical advancements required for the implementation of electric vehicles. This increase leads to a longer drive distance between recharges. Aside from material development, full lithium-ion cell design parameters have the potential to greatly influence fabricated cell energy density. The following work highlights the impact of these full-cell design parameters, investigating the effect of a negative to positive capacity ratio, positive electrode porosity, positive electrode active material content, and overall charge voltage on stack volumetric energy density. Decreasing the N:P ratio or increasing active material content results in an almost identical volumetric energy density increase: ~4%. Decreasing the positive electrode porosity from 40–30% or increasing the charge voltage from 4.2–4.35 V also results in an almost identical increase in volumetric energy density: ~5.5%. Combining all design changes has the potential to increase stack volumetric energy density by 20% compared to the baseline cell design.

Published: October 2023

A torção testicular é uma urgência urológica caracterizada pela rotação do testículo, comprometendo o fluxo sanguíneo e podendo levar à necrose testicular se não tratada prontamente. O quadro clínico típico inclui dor escrotal aguda, edema e eritema, sendo o diagnóstico primariamente clínico e auxiliado por ultrassonografia com Doppler. O tratamento imediato é crucial, geralmente envolvendo cirurgia para desrotação e fixação do testículo. Alternativas como a desrotação manual são temporárias e não excluem a necessidade de intervenção cirúrgica posterior. A educação sobre os sintomas e a necessidade de intervenção imediata é vital para prevenir complicações graves, incluindo a perda testicular e infertilidade.

Published: October 2023

Este trabalho objetivou analisar o volume de condensado que se precipita no evaporador de um sistema de refrigeração, sua relação com o COP do sistema, e com a umidade relativa do ar que o circunda. Constatou-se forte correlação do volume de condensado com a umidade relativa do ar, mostrando que os ganhos são mais significativos à medida que a quantidade de vapor d’água presente na atmosfera se aproxima de seu valor de saturação. Concluímos, por meio dos valores obtidos, que um ar condicionado comercial modelosplit de 18000 BTU, ligado por 12 horas/dia, com umidade relativa do ar em torno de 77%, é capaz de precipitar até 396,2L de água ao mês. Em termos econômicos, isso representa uma diminuição de R$ 0,72 na tarifa de água, nessas condições específicas. Além disso, a água condensada no evaporador é desmineralizada, característica que permite sua destinação para, por exemplo, encher ou completar reservatórios de líquido de arrefecimento de motores a explosão, o que se mostra economicamente viável, dado que o preço médio de mercado da água desmineralizada éR$ 20,00/L.Os resultados podem ser considerados promissores, uma vez que o volume de condensado coletado é significativo mesmo para pequenos sistemas de refrigeração, o que pode ser um importante aliado nas práticas sustentáveis que visam a reciclagem e o uso racional da água potável disponível em nosso planeta. Consideramos nesse estudo, um sistema de refrigeração próprio para salas de 40m², e os ganhos podem ser muito mais significativos em escala industrial.

Antecedentes para la enodiplomacia en Chile (1960-2010)
Authors: Pszczolkowski Philippo , Cañón Pablo , Castro Amalia
Published: October 2023

Chile inició el proceso que lo llevaría a convertirse en potencia vitivinícola mundial en la década de 1980, algo que se logró gracias a la acción conjunta de la industria, el sector técnico-profesional y el Estado. El objetivo de este estudio es develar el papel jugado por la enodiplomacia en dicho proceso y las principales características del mismo. Se utiliza la metodología del “actor participante” asociada a las ciencias sociales, basada en testimonios directos de época y entrevistas en profundidad durante el primer semestre de 2022. Observamos una evolución de la elaboración y apreciación del vino chileno, jerarquizado por la política exterior chilena, desde la década de 1980 hasta 2022 como máxima expresión, que lo llevó a posicionarse como potencia vitivinícola. Se concluye que dicho posicionamiento se logra gracias a una enodiplomacia activa desplegada por el Estado chileno, apoyada por academia y mundo técnico, que mejoraron la tanto comercialización como el status del vino chileno en el país y el mundo. En ello se distinguen dos corrientes: una regida por el paradigma francés (dominante) y otra, más reciente, signada por el paradigma hispano criollo, que apunta a revalorizar variedades y productos patrimoniales.

Authors: Huo Jiayan , Li Huayu , Roveda Janet , Quan Stuart F , Li Ao
Published: October 2023

Sleep is crucial for overall health and well-being. Analyzing sleep
stages and the frequency of arousal can enhance our understanding of
sleep quality and help protect individuals’ sleep health. The objective
of this study is to explore the development and application of
multi-task deep learning model that can simultaneously detect sleep
arousal and score sleep stages. We employed a task-incremental approach
to develop the multi-task deep learning model. For development and
testing, 1069 polysomnography records were incorporated. Additionally,
the model’s fairness was assessed across various subgroups, including
sex, age, and ethnicity. Beyond performance evaluation, we investigated
the intermediate features extracted by the model from the raw ECG
signal. The multi-task deep learning model achieved a Cohen’s 𝜅 of 0.68
for sleep stage prediction and an area under the receiver operating
characteristic (AUROC) of 0.94 for arousal detection. Additionally, the
model showed consistent performance across different subgroups. The
analysis of the interpretability of the intermediate features validated
their applicability and adaptability to related tasks in sleep analysis.
This study demonstrated the capacity of the multi-task deep learning
model to score sleep stages and arousal simultaneously with substantial
precision using a single-lead ECG. This research offers a promising
avenue for advancing incremental learning and multi-task deep learning
models in sleep analysis.
Natural caustics in backward path tracing
Authors: Halayka Shawn
Published: October 2023

In this paper we introduce a natural method for producing both refraction and reflection caustics in backward path tracing (e.g. bouncing around an eye ray in the scene until a light is found).

These caustics do not rely on a light location, and as such, do not rely on bidirectional or forward path tracing.

As such, these caustics allow for as many light sources as one would care for; the shapes and positions of the lights are completely arbitrary (can be bunny shaped, etc).

We use the standard Cornell box for testing the backward path tracer.

Published: October 2023

When developing a technology based on single-photon avalanche diodes (SPADs), the SPAD characterization is mandatory to debug, optimize and monitor the microfabrication process. This is especially true for the development of SPAD arrays 3D integrated with CMOS readout electronics, where SPAD testing is required to qualify the process, independently from the final CMOS readout circuit. This work reports on a characterization and monitoring platform dedicated to SPAD testing at die and wafer level, in the context of a 3D SPAD technology development. The platform relies on a dedicated integrated circuit made in a standard CMOS technology and used in different configurations from a prototype printed circuit board (die-level testing) to active probe cards (wafer-level mapping). The platform gives full access to SPAD characteristics in Geiger mode such as the dark noise, photon detection efficiency and timing resolution. The integrated circuit and its configuration are described in detail as well as results obtained on different SPAD test structures. In particular, the dark count rate mapping demonstrates the benefits of testing SPADs at wafer level at the R&D stage.
The Effect of Functional Magnetic Resonance Imaging Connectivity on Resting Motor Threshold Transcranial Magnetic Stimulation in Schizophrenia Participants
Authors: Lewis Connor , Mittal Neil , Pandurangi Anand , Mehta Urvaksh , Hadimani Ravi
Published: October 2023

Schizophrenia is a neurological disorder known to influence the motor region. Transcranial magnetic stimulation (TMS) is a non-invasive neuromodulation technique being investigated as a treatment for schizophrenia. Resting motor threshold (RMT) is the dosage parameter for TMS treatment protocols and is known to vary between participants with limited understanding of the drivers of this variance. Previous investigations have used functional magnetic resonance imaging (MRI), diffusion tensor imaging (DTI), and individual level neuroanatomy to explain RMT variability. Our previous investigation showed neuroanatomy influences RMT in both schizophrenia and healthy populations and this relationship was weakened by the presence of schizophrenia. In this study, 54 participants with schizophrenia-diagnosed, who were antipsychotic naive and 43 non-impaired controls underwent single pulse TMS, structural magnetic resonance imaging, and fMRI. An independent component analysis (ICA) was used to process fMRI data into 25 distinct channels where correlations were derived between channels. Linear and multiple regression models were used to evaluate first, the influence of these channel interactions on RMT followed by their influence when individual level neuroanatomy was also considered. We found that between-channel functional connectivity was altered in individuals with schizophrenia and that fMRI can contribute to prediction of RMT, but differently in both cohorts and to a lesser degree than individual level neuroanatomical measures. This suggests that functional connectivity influences TMS response and fMRI might help in dosage calculations of clinical TMS protocols.
A Simple Low-Cost Gate Drive for Multiple SiC MOSFETs for Single-Switch Induction Heater
Authors: Paul Arun
Published: October 2023

Two popular application domains of low-power single-switch induction heating systems are cooking and off-line sealing of plastic/glass containers. Sealing operation could be using cap or capless, the latter is preferred because of ease of inspection of sealing quality. For near continuous-duty operation of the converter, due to the superior power loss and thermal characteristics, two SiC MOSFETs connected in parallel are preferred for the switch. The design of gate drive circuit (GDC) for these devices is complicated. The desired gate voltage is not only highly asymmetrical, due to small gate threshold voltage, it is sensitive to ringing in gate signal, the range of negative bias is also constrained. The duty-cycle of the high-frequency gate signal for the switch is small. This article proposed a novel GDC where, using a single-polarity control power supply, a pulse-transformer is used to feed desired asymmetrical gate voltage to several isolated devices. To avoid spurious turn-on, this research further proposed a novel transformer for feeding bi-polar asymmetrical gate voltage with requisite signal and power-noise isolation to effectively use of respective Kelvin source terminal. The proposed idea has been completely validated by driving two SiC MOSFETs in a power converter for high-speed off-line induction sealing applications.
Understanding BRC-20: Hope or Hype
Authors: Wang Qin , Yu Guangsheng
Published: October 2023

BRC-20 (short for Bitcoin Request for Comment 20) token mania was a key storyline in the middle of 2023. Setting it apart from conventional ERC-20 token standards on Ethereum, BRC-20 introduces non-fungibility to Bitcoin through an editable field in each satoshi (0.00000001 Bitcoin, the smallest unit), making them unique. In this paper, we pioneer the exploration of this concept, covering its intricate mechanisms, features, and state-of-the-art applications. By analyzing the multi-dimensional data spanning over months with factual investigations, we conservatively comment that while BRC-20 expands Bitcoin’s functionality and applicability, it may still not match Ethereum’s abundance of decentralized applications and similar ecosystems.
A Framework for Migration of Microservices based Applications to Serverless Platform with Efficient Cold Start Latency
Authors: Raj Vinay
Published: October 2023

Serverless computing has become a very popular cloud-based solution for
designing, testing and deploying the applications as serverless
functions. Serverless computing has become a buzzword in both industry
and academia as many large IT giants have rolled out their own
serverless platforms. Independent design, deployment and auto
scalability are its major features with Function-as-a-Service (FaaS) as
its popular implementation. On the other hand, microservices are an
emerging trend for design of large enterprise applications as many
companies like Amazon, Uber and Spotify have already migrated their
existing applications to microservices style. However, with the advent
of serverless platforms, to design efficient applications with simpler
infrastructure management, reduced operational overhead and cost factor,
migrating microservices to serverless has become inevitable.
Additionally, existing studies report that serverless platforms suffer
from cold start latency. Therefore, in this paper, a framework is
proposed which has two phases: (i) an empirical investigation to find
out the impact of programming language on the cold start of serverless
functions and (ii) an approach for migration of microservices to
serverless platforms. The evaluation results help us to identify the
platform with low cold start latency and also recommend the choice of
programming language with lower latency. After migrating the
containerized microservices to serverless, a comparison in terms of
performance is conducted. The applications designed as serverless
functions exhibit better response time and throughput compared to
containerized microservices.

Authors: Carballo-Huerta María Azucena , González-Ramírez Gustavo Alejandro
Published: October 2023

El contexto social, económico, tecnológico y ambiental marcan la necesidad de actualizar contenidos y métodos de trabajo en el diseño curricular para dar mayor certeza al estudiante en su desempeño profesional. El diseño centrado en el usuario (dcu) ha sido una de las asignaturas que se han insertado en los planes 2020 de las licenciaturas del Departamento de Arquitectura y Diseño. El proyecto realiza una revisión bibliográfica del estado de la técnica del modelo dcu para identificar las mejores prácticas, autores y contenidos que sirvan de guía para la capacitación docente y definir un eje temático rector en el departamento. El modelo dcu considera aspectos más allá de la estética, analiza usabilidad y experiencia de los ambientes, objetos y mensajes durante el proceso de desarrollo, lo cual permite al usuario obtener alternativas superiores ante las diferentes opciones de un producto. En la literatura se encuentran una serie de técnicas en torno al concepto de diseño centrado en el usuario, entre ellas destacan el design thinking, diseño afectivo, diseño emocional, experiencia de usuario e ingeniería KANSEI, entre otras. La revisión de literatura se realizó en publicaciones indizadas de EBSCO en los últimos 7 años relacionadas, para identificar modelos, técnicas y contenidos que sirvan de base para el diseño de un curso de formación docente. La discusión colegiada de estos modelos permitirá llegar a acuerdos sobre su implementación en aula. Realizar dinámicas que puedan compartirse en la práctica será enriquecedor. El aprendizaje de estos conceptos permeará en la práctica profesional de los egresados.
Percepción y satisfacción del visitante de museos y su influencia en el diseño de iluminación
Authors: Bazan Liliana Natalia , Ajmat Raúl Fernando
Published: October 2023

La luz es un elemento indispensable para la apreciación de los objetos; pero a la vez una de las mayores causas de su deterioro, lo que genera conflictos en el doble rol de los museos de preservar el patrimonio a la vez que exhibirlo al público. 
El presente trabajo busca analizar cómo las decisiones de diseño de iluminación y las formas de utilización de luz natural y artificial dentro de las salas de exhibición en museos afectan la percepción de los visitantes del espacio iluminado y los objetos expuestos, así como su satisfacción con la iluminación y consecuentemente con su visita. Para esto se indagó en las preferencias lumínicas de los visitantes y su satisfacción, que fueron contrastadas con mediciones in situ de magnitudes fotométricas (luminancia e iluminancia) en dos museos de Argentina. 
Los resultados indican qué rangos de iluminancias similares pueden generar sensaciones lumínicas a nivel general del museo altamente diferenciadas, prestando particular atención a las relaciones entre luminancias, tanto dentro como entre salas.  
Se delinean recomendaciones de diseño a partir de los resultados obtenidos, orientadas a mejorar la satisfacción de los visitantes con la misma y con su visita.
Effect of instructional design based on cognitive load theory on students’ performances and the indicators of element interactivity
Authors: Kala Nesli , Ayas Alipaşa
Published: October 2023

Thermodynamics is one of the most complex topics in chemistry. Cognitive Load Theory claims that the complexity of a subject is mainly due to element interactivity - how many elements an individual must organise simultaneously in her/his working memory to master a topic. The simultaneous processing of various chemistry and mathematics concepts to learn thermodynamics puts a strain on the working memory capacity of the learner. Accordingly, what kind of change occurs in a learner’s cognitive processes according to the level of element interactivity is an issue that needs to be investigated. The aim of this study is to reveal the basic indicators of element interactivity and investigate the effects of instructional design on understanding subjects with different element interactivity levels. With this objective in mind, educational software comprising eight distinct sessions for instructional design was developed in accordance with the Cognitive Load Theory. The sample consisted of 37 freshmen who were taking classes in the Chemistry Department of a public university in Turkey. The instructional design was implemented with the experimental group while the control group followed the lecturer's instructional design. The results indicate that, in terms of the cognitive load in the learning process, the study time and the learning at the retention and transfer level are among the basic indicators of the element interactivity. This study also determined that the instructional design that is developed according to Cognitive Load Theory can provide effective learning at the retention and transfer levels in subjects with high element interactivity.

BACKGROUND: Asthma is considered one of the urgent medical and social problems of the XXI century. In recent years, not only an increase in the incidence, but also an increase in the prevalence of severe forms of asthma has been noted in all countries of the world. The effect of the sensitization spectrum on the severity and level of asthma control has not been studied enough.
AIM: Evaluate the importance of sensitization spectrum to aeroallergens in severe asthma patients as indicators for disease exacerbation risk.
MATERIALS AND METHODS: Single-center cross-sectional study at North-Western State Medical University n.a. I.I. Mechnikov. Examined 93 severe asthma patients. Analysis covered demographic traits, comorbidities, hereditary history, living conditions, exacerbations, past-year hospitalizations, medications, spirometry, and specific IgE presence for 10 aeroallergens.
RESULTS: Aspergillus fumigatus specific IgE notably impacted asthma control. Disease exacerbation risk was 8.4 times higher with A. fumigatus sensitization. Multivariate logistic regression revealed higher risk with A. fumigatus sensitization (4.79), fixed obstruction (6.2), systemic steroids use (5.85), indoor mold exposure (4.45), and familial asthma history (2.53).
CONCLUSION: A. fumigatus sensitization significantly influences asthma course and control, worsening prognosis. Targeted examination of patients measuring sIgE levels for common aeroallergens is necessary to identify control obstacles. The results of the study were previously reported at the All-Russian Congress on Medical Microbiology, Clinical Mycology and Immunology and published in the form of abstracts in the journal Problems in medical mycology, 2022, Vol. 24, No 2.
