SYNTHESIS, PHOTOREACTIVITY AND INTERACTION WITH DNA OF A NEW PROTOTYPE RUTHENIUM COMPLEX FOR THE DEVELOPMENT OF PHOTOCHEMOTHERAPEUTIC AGENTS. A new ruthenium polypyridine complex, cis-[Ru(bpy)2(1- meimN)(4-pyCHO)](PF6)2 (WP1), where 1-meimN and pyCHO are the ligands 1-methylimidazole and 4-pyridinecarboxaldehyde, respectively, was prepared as a prototype for use in phototherapeutic process. This compound was characterized by electronic absorption in UV-Visible, FTIR, 1H and 13C NMR, cyclic voltammetry, besides DFT that supported its molecular structure. The compound WP1 was photoreactive, where blue or green light promoted the release of 4-pyCHO ligand. Additionally, this compound was able to interact with DNA, mainly through electrostatic interactions showing photoinduced nuclease activity. There is also photoproduction of superoxide ions using blue or green light suggesting a route for DNA damage. These promising results opened new opportunities for the potential use of this system and analogues as phototherapeutic agents, which is an ongoing study in our lab.

Authors: Teófilo Karine , Sicupira Lázaro , Silvério Flaviano
Published: January 2024

Tolfenpyrad is an insecticide and acaricide of the pyrazole class, which has been used to control pests in cereal, legume and vegetable crops. Despite its high efficiency, this insecticide is considered highly toxic to humans by Brazilian legislation. Therefore, this study aims to optimize and validate liquid-liquid extraction with low temperature purification followed by analysis by high-performance liquid chromatography with diode array detection to determine tolfenpyrad in water. The results showed that the optimal extraction conditions were achieved using only acetonitrile as extracting phase and 60 min as freezing time. Under these conditions, the extraction method was selective, accurate, and precise, with a recovery of 102.41% and a relative standard deviation of 11.29%. The method was linear from 2.0 to 150.0 µg L-1, with a limit of quantification of 2.0 µg L-1, and the matrix effect was –7.67%. The half-life was 23 days (with sunlight) and 30 days (no sunlight).

В статье представлены результаты исследования восприятия стоматологической помощи российских и иностранных студентов: для иностранных студентов более приоритетным является посещения стоматолога с целью профилактического осмотра, для российских студентов определяющим является необходимость лечения уже возникших заболеваний и / или заботе об эстетической составляющей. Возраст первого визита к стоматологу российские респонденты отнесли к периоду формирования молочного и переходного прикусов. Согласно опросу, в выборке иностранных студентов первый визит осуществлялся в периоды младшего школьного и подросткового возраста. По сравнению с ответами иностранных студентов, среди российских респондентов наиболее распространен «страх при посещении врача стоматолога как результат детских переживаний и первого опыта посещения стоматолога». В связи со сложностями коммуникации в системе «врач-пациент» и организационными аспектами оказания стоматологической помощи (например, нарушение времени приема) высок процент иностранных студентов, относящихся с недоверием к стоматологическим услугам в России.

Unveiling the Factors Behind Under-Representation of Women in Leadership Positions within Dental Academia
Authors: Khan Muhammad Awais , Naeem Noor-i-Kiran
Published: January 2024

Introduction: Women play a vital role in the health sector of Punjab, Pakistan occupying 68% percent of total seats for undergraduate students in Pakistani dental colleges. However, this proportion decreases as one moves up in the organizational hierarchy with men dominating leadership positions in Pakistan. This has led to negligible women representation in dental academia.
Objectives: This study aimed to explore female dental academia leaders’ perspectives on possible reasons behind the under-representation of women in leadership positions in the dental academia of Punjab, Pakistan.
Methods: A qualitative, phenomenological research design using semi-structured interviews and purposive sampling was conducted from March 2018 to February 2019. Eight out of 10 invited female dental academia leaders working in public sector dental colleges of Punjab participated in individual in-depth interviews. Data were organized in Atlas-ti and analyzed through thematic analysis.
Results:
Thematic analysis led to the development of six themes: 1) Family responsibilities, 2) Work environment, 3) Gender bias, 4) Lack of Counseling, 5) Financial matters, and 6) Transport issues and long distance from the workplace. Sub-themes further elaborate on the findings and provide deep insight into the problem.
Conclusion: The problem of female underrepresentation in dental academia leadership is multifaceted. Reserving separate funds for women, arranging career counselling sessions, decreasing working hours during special circumstances, and changing attitudes towards women’s role in households will help overcome the problem. The study opens a path for future research on the development of interventions or strategies to overcome the reasons.

Colonización de arrecifes artificiales en Bahía Coliumo, Chile
Authors: Pizarro Alfonso , Alveal Krisler , Romo Héctor
Published: January 2024

Experiencias de construcción de arrecifes artificiales, a pequeña escala, iniciadas durante 1981, en Bahía Coliumo, han permitido comprobar: a) un efecto moderado, pero significativo, de incremento de la abundancia de invertebrados y algas bentónicasal instalar las estructuras; b) una relación directa entre la abundancia de estos organismos y la densidad de las estructuras; c) la selección de microhábitat y refugios por las especies colonizadoras; d) diferencias batimétricas de las especies colonizadoras y sus abundancias y de tasa de colonización de los arrecifes. Sin embargo, a diferencia con lo observado en arrefices instalados en otras partes del mundo, los arrecifes de Bahía Coliumo, no han sido colonizados por peces. Esta respuesta es atribuible a una notable pobreza de ictiofauna en la bahía. Otra característica del área de estudio, claramente desfavorable para esta actividad, fue la existencia de desechos de explotación de madera (aserrín), en amplios sectores del fondo. No obstante la existencia aún de fondos poco o no contaminados, en áreas relativamente extensas del margen costero de la bahía, justifica esfuerzos para aumentar la productividad del área, mediante la generación de hábitat más heterogéneos

Published: January 2024

Se describen los huevos y las larvas en estado de saco vitelino de la sardina común (Strangomera bentincki) y del machuelo (Ethmidium maculatum). Los huevos fueron recolectados en el mar y las larvas obtenidas en el laboratorio. Los huevos en ambas especies son típicamente planctónicos y morfológicamente muy similares, con vitelo segmentado, sin gota oleosa, y con espacio perivitelino reducido. El carácter principal que permite separar los huevos de ambas especies es el tamaño. En S. bentincki el diámero varía entre 0,89 y 1,03 mm (n = 96; 0,96 mm promedio) y en E. maculatum entre 1,25 y 1,40 mm (n = 47; 1,30 mm promedio). No se detectó sobreposición en los rangos de tamaños de los huevos. En el momento de la eclosión las larvas de 5. bentincki miden de 2,5 a 3.2 mm LN (longitud nolocordal) y las de E. maculatum de 3,7 a 3.9 mm LN. completándose la reabsorción del vitelo entre los 5.1 y los 5,3 mm LN y entre los 6,4 y los 6.5 mm LN, respectivamente. El tamaño del saco vitelino y el número de miómeros preanales son caracteres importantes para la separación de las larvas en estado de saco vitelino de ambas especies.

Authors: Olivares Jorge
Published: January 2024

Estudios realizados en la bahía de Coquimbo muestran la presencia de un ciclo estacional de temperatura, caracterizado por la existencia de una termoclina en el período de primavera-verano. La distribución superficial de salinidad y silicato disuelto es afectado por el aporte del río Elqui durante gran parte del período de estudio, cuyo caudal se vio aumentado en diciembre de 1978 por los deshielos cordilleranos. El análisis de refracción de olas efectuado en la bahía, permite caracterizar dos zonas, una en la cual la energía es baja y se ubica en el sur de la bahía y otra con alta energía, la que se encuentra en el sector frente al faro de La Serena.

Ícono frente al arte:
Authors: Hidalgo Varela Leandro
Published: January 2024

En este artículo se analiza la dimensión del ícono, entendido como manifestación de Dios hacia el hombre, y cómo a través de este medio se crea un encuentro. Esta relación se estudia en el ámbito del arte, específicamente el que está inspirado en motivos religiosos; desde aquí se hace un análisis de las particularidades del ícono frente a éste. Para esto, se rastreará el origen del ícono y las características esenciales que lo han constituido como la imagen de culto por excelencia, frente a todo el arte religioso que se ha ido produciendo a lo largo de la historia del arte. Para ello, se busca vislumbrar cómo los grandes artistas clásicos han cambiado el enfoque de lo plasmado y han puesto la mirada en la belleza estética, más que en el trasfondo de la imagen realizada; de esta manera, es clave el rol que juega el artista en ambos tipos de producción.
La tragedia Ática a la luz de la filosofía de Nietzsche
Authors: Sandoval Castro Iván
Published: January 2024

Nietzsche da origen a la duplicidad de los términos que denominó como lo apolíneo y lo dionisíaco, realizando a su vez, un viaje de profundo contenido filosófico y filológico en su obra de juventud que lleva como título: El nacimiento de la tragedia. El presente trabajo tiene por finalidad reflexionar a través de la distinción y contraposición entre estos dos conceptos llevada a cabo por el joven Nietzsche en dicha obra, así como también, en indagar en el desarrollo de la tragedia griega como el suceso histórico en el que tanto lo apolíneo como lo dionisíaco coexisten armónicamente gracias a un acto milagroso de la voluntad helénica, intentando a su vez, responder a la pregunta sobre el origen de la tragedia ática. Luego se hará énfasis en la posterior decadencia de la tragedia a través de autores de la talla de Eurípides, y en cómo repercute en este suceso la figura de Sócrates, respondiendo así finalmente a la pregunta por la decadencia de la tragedia ática.

Insect infestation and low soil fertility are the major constrictions in okra production and various tactics have been recommended for increased production. An experiment was conceived to explore the effects of different levels of pig manure on the performances and severity of damage caused by Podagrica uniforma Jacq. infestation on okra in South Western, Nigeria. The research was arranged in Randomized Complete Block Design (RCBD) with four treatments (0 t.ha-1, 5 t.ha-1, 10 t.ha-1, 15 t.ha-1 and 20 t.ha-1) replicated thrice. Okra growth, fruit yield, insect population and severity of damaged leaves were assessed and exposed to the Analysis of Variance, and Duncan Multiple Range Test (DMRT) at a 5 % level of significance was used to separate significant treatment means. The study outcomes revealed that okra growth and yield parameters were directly proportional as the pig manure rates increase. A similar trend was equally recorded for P. uniforma population in okra plants enriched with variable rates of pig manure, okra supplied with 20 t.ha-1 of pig manure exhibited the highest growth, yield performance and P. uniforma population. While the severity of leaf damage caused by P. uniforma was in descending order, very low in okra enriched with varying levels of pig manure as compared to the damage recorded in control. The trial showed that okra growth and yield was significantly (p<0.05) enhanced by the application of 20 t.ha-1 pig manure with a resultant reduction in the severity of damaged leaves caused by P. uniforma infestation.

Afanasy Nikitin’s Voyage Beyond Three Seas [Khozhenie za tri morya], one of the most famous Old Russian travel accounts, was created in the second half of the fifteenth century, at the boundary of the late medieval and early modern periods. By understanding travel writing as a translation phenomenon, this paper will focuson how this merchant from Muscovite Russia translates an encounter between East and West during his seven-year journey through Persia, India, and other foreign lands, adapting linguistically to the exotic environment. Nikitin’s multilingual travelogue, written in Old East Slavic and a patois of Arabic, Persian, and Turkic, reveals a complex hybrid identity manifested through the traveller’s syncretic Christian-Muslim habits.

The effect of remittances on financial literacy in Mexico
Authors: Cuecuecha Mendoza Alfredo
Published: January 2024

This article studies the impact of remittances on financial literacy and its components using data for ENIF 2021 in Mexico. Using instrumental variables, random matching estimators and non-parametric estimations that control for the endogeneity of remittances and other econometric challenges, the study is the first to find that remittances increase the average level of financial literacy, and its components of financial knowledge, behavior, and attitudes. The effect is not monotonic, since the study finds that remittances reduce the probability of showing high levels of literacy, as well as that of its components of financial knowledge, behavior, and attitudes. Non-parametric estimations show that remittances move the distribution of financial literacy outcomes towards the center of the distribution, which explains why average values of financial literacy outcomes are above the average. These results may indicate that households acquire financial literacy through a process of learning by doing, which shows decreasing returns. They highlight the need for specific policies to increase the level of financial literacy among households that receive remittances. The limitation of the study is the lack of panel data.
Financial Literacy of Workers in the Tourism Industry in Mexico in 2023: a Structural Equations Approach
Authors: García-Santillán Arturo , Venegas-Martínez Francisco , Mendoza-Rivera Ricardo Jacob
Published: January 2024

This paper attempts to examine the level of financial knowledge of workers in the tourism industry in Mexico through the Structural Equations Methodology (SEM). The type of sampling is non-probabilistic by self-determination. A questionnaire is applied to 500 workers, in 2023, from Mexican companies in the tourism sector considering the following 7 issues: investment, savings, credit, insurance, pensions, expenses and budgets. The SEM allows bring to light the financial knowledge that the surveyed workers have about these issues. Based on a factor structure obtained from the confirmatory analysis, which presents good goodness of fit, structural adjustment, and parsimony, the main findings are: 1) in terms of credit, workers give importance to the requirements requested by financial institutions and consider that they are easy to interpret and comply with, 2) in terms of retirement fund accounts, workers feel confident in institutions that manage their retirement savings and are clear about commissions, 3) in terms of savings, workers perceive that bank accounts have been adapted to their needs since banks have become very flexible in terms of requirements for opening and initial amounts with clear and complete account information, 4) in terms of investment, workers hardly acquire bank promissory notes, and 5) regarding life insurance, workers express the ease that exists to contract insurance, although the cost is limited. The results obtained have practical implications for the tourism sector to continue promoting the habit of saving and the use of financial services and products to which the worker can have access, since this financial knowledge translates into more organized employees in their financial affairs.
A Policy and Evaluation Framework for Sustainable Transitions - An Energy Policy Approach
Authors: Sousa Joana
Published: January 2024

The climate change and the social crisis launched the basis for the policy discussion about future trajectories of development and sustainability. Innovation policies are expected to promote the transformation of complex socio-technical systems and call for fundamentally different societal production and consumption patterns. This is strictly associated with energy systems and energy policies. A policy framework was conceptualized considering three levels approach: the policy shape at the micro level, the policy context at the meso level and the policy universe at the landscape level. Possible failures were classified according to the levels. To minorize these failures, an evaluation framework was developed considering both the policy outputs and the social impact outcomes - an example of renewable energy communities was applied to the policy and evaluation framework. The intended outcome is a reconfiguration of sociotechnical innovation systems through new technologies’ development, new actor-network and institutional reconfiguration promoting changes in economic dynamics as well as the development of new social competencies with learning, reflexivity and feedback loops for overcoming obstacles.

Authors: Moreira Sr Ailton , Santos Sr Manuel Filipe
Published: January 2024

BACKGROUND

In recent years, the concept of telemedicine and telehealth has been expanded a lot, and consequently, healthcare institutions are seeking innovative strategies to adopt these concepts in their services. The healthcare domain faces many challenges in terms of human resources allocation, systems integrations, and data interoperability. The adoption of an open-data approach in an omnichannel mobile companion can have a huge potential in how these strategies are designed. This research seeks to study the adoption of an open-data approach for an omnichannel mobile companion for personalized care services. Moreover, this paper will present a proof-of-concept and a demonstration regarding the design and implementation of an omnichannel mobile companion for personalized care services based on openEHR specifications for patient contact in ambulatory surgery.

OBJECTIVE

This research study aims to resolve some of the well-known identified gaps in the healthcare domain regarding personalized care services provided to patients (such as fragmented communication channels, lack of systems integration and interoperability, poor data access in real-time for timely decision-making, and overloaded health professionals) by leveraging the open-data approach in an omnichannel environment. Thus, this study aims to apply an innovative approach in this context to overcome the identified gaps and challenges in the healthcare domain.

METHODS

A case study and proof-of-concept method was applied in this research study, by designing a prototype of an omnichannel mobile companion for personalized care services. This will be materialized through a demonstration of a specific use case of the application of this approach.

RESULTS

Using an omnichannel mobile companion combined with the open-data approach allowed us to address and overcome the main gaps identified previously. Thus, this approach brings several gains to the healthcare domain and personalized care services such as an enhanced patient-centered approach, smooth and seamless access to health information, better systems and channels integration and data interoperability, more efficient data analytics and real-time insights, efficient resource allocation, and more. Moreover, these gains translate into better patient user experience with the care service provided to them.

CONCLUSIONS

Despite the challenges encountered in carrying out this research study, it was possible to address and overcome the gaps identified. However, several issues persist, which require more attention in the field of personalized care services. The strategy proposed in this research study effectively overcame a substantial part of the challenges inherent to personalized care services but, additional challenges remain and deserve further consideration.
Mobile Phone-Assisted Lifestyle Modifications to Reduce Mortality Due to Coronary Heart Disease – the results of a Randomized Controlled Clinical Trial from Pakistan (Preprint)
Authors: Ismail Javed , Strodl Esben , Ma Jun , Ansari Junaid , Kiat: Hosen
Published: January 2024

BACKGROUND

Cardiovascular disease is prevalent in Pakistan and is a major cause of premature mortality. The unhealthy diet, cigarette smoking, pollution, sedentary lifestyle, and psychological factors such as depression and anxiety are among the major modifiable risk factors. The advancement of communication technology can bring behavioral changes in personalized health education and healthcare management. The study explores a mobile phone text messaging intervention program’s effectiveness in reducing mortality in patients with coronary artery disease.

OBJECTIVE

The study explores a mobile phone text messaging intervention program’s effectiveness in reducing mortality in patients with coronary artery disease and providing primary prevention for their immediate caregivers.

METHODS

A randomized controlled clinical trial was conducted in 3 cardiac-specific tertiary care hospitals in Karachi, Pakistan. The participants were patients having their first cardiac events and their nominated caregivers. Patients and their caregivers were randomized into two groups, intervention (IG) or usual care group with no-intervention (NIG). For the participants in the IG, daily health text messages were sent to their mobile phones 5 days per week. Patients in both groups were followed up at 6 monthly intervals.

RESULTS

Overall, there were 86 (3.2%) deaths during the study, 41 deaths in intervention and 45 deaths in non-intervention group. Caregivers were excluded from the analysis as there were no deaths among them. Kaplan–Meier survival analysis showed that the mean survival time in IG (534 days) and NIG (514 days) were not significantly different. Cox-regression analysis showed that old age, unemployment, history of diabetes, hypertension, and non-physical activity were independently associated with mortality in first-ever CAD patients.

CONCLUSIONS

The intervention of mobile phone text messaging to promote a healthy lifestyle was not effective in reducing the mortality among patients in Pakistan. Future interventions for patients with CAD with their first cardiac event living in Pakistan should specifically target the modifiable risk factors of unemployment, management of diabetes and hypertension, and non-physical activity to reduce the risk of premature mortality in this population.

CLINICALTRIAL

The clinical trial is registered at the Australia New Zealand Clinical Trial Registry

BACKGROUND

Healthcare systems around the world face numerous challenges. Recent advances in artificial intelligence (AI) have offered promising solutions, particularly in diagnostic imaging.

OBJECTIVE

This systematic review focused on evaluating the economic feasibility of AI in real-world diagnostic imaging scenarios, specifically for dermatological, neurological, and pulmonary diseases. The central question was whether the use of AI in these diagnostic assessments improves economic outcomes and promotes equity in healthcare systems.

METHODS

This systematic review has two main components: economic evaluation and equity assessment. We used the PRISMA tool to ensure adherence to best practices in systematic reviews. The protocol was registered with PROSPERO, and we followed the CHEERS guidelines for economic reviews and PRISMA-E for equity. The search was conducted in the PubMed, Embase, Scopus, and Web of Science databases. Methodological quality was assessed using the following checklists: CHEC for economic evaluations, EPHPP for equity evaluation studies, and Welte for transferability.

RESULTS

The systematic review identified nine publications within the scope of the research question. The majority of studies addressed economic evaluation (88.9%), with most studies addressing pulmonary diseases (6 - 66.6%), followed by neurological diseases (2 - 22.3%) and only one study addressing dermatological diseases (11.1%). These studies had an average quality access of 87.5% on the CHEC checklist. Only two studies were found to be transferable to Brazil and other countries with similar health context. The economic evaluation revealed that 87.5% of studies highlighted the benefits of using AI in dermatology, neurology, and pulmonology. The only study assessing equity identified AI-assisted underdiagnosis, particularly in certain subgroups.

CONCLUSIONS

This review underscores the importance of transparency in the description of AI tools and representativeness of population subgroups to mitigate health disparities. As AI is rapidly being integrated into healthcare, detailed assessments are essential to ensure that benefits reach all patients, regardless of sociodemographic factors.

Health Information Exchange Use by Healthcare Workers in Japan: Retrospective Cohort Study (Preprint)
Authors: Suzumoto Jun , Mori Yukiko , Kuroda Tomohiro
Published: January 2024

BACKGROUND

A health information exchange (HIE) system enables healthcare providers and patients to exchange clinical data electronically across multiple healthcare institutions. Sharing medical information appropriately using HIE has several benefits in clinical practice. More than 200 HIEs have been implemented in Japan and are currently operational. However, in Japan, little academic research has been conducted on whether healthcare workers use HIE in the institutions where it was introduced. The primary objective of this study was to clarify the usage rate, usage frequency, and usage bias of large-scale HIEs in Japan by analyzing audit logs.

OBJECTIVE

The primary objective of this study was to clarify the usage rate, usage frequency, and usage bias of large-scale HIEs in Japan by analyzing audit logs.

METHODS

We conducted a retrospective cohort study. The research subjects were HIEs joined by over 100 facilities and 10,000 patients. Each healthcare worker’s profile and audit log data for HIE were collected. The following four analyses were conducted: First, we counted the annual number of days of HIE use by each hospital doctor in the financial year (FY) 2021/22 and calculated the Gini coefficient. Second, we calculated monthly HIE use frequency distribution for each facility type in FY2021/22. Third, we calculated each facility type's monthly HIE usage rate in FY2021/22. Fourth, we compared the monthly HIE usage rate by medical institution for each HIE and the proportion of man-days of HIE use by occupation for each HIE.

RESULTS

Twenty-four HIEs were identified as candidates for data collection, and we analyzed data from seven HIEs. Among the hospital doctors, 93.5% had never used HIE during the available period in FY2021/22. The Gini coefficient for each hospital doctor's estimated annual HIE usage days was 0.984. The monthly HIE usage rates were 0.482 (0.470-0.487) for hospitals, 0.243 (0.230-0.247) for medical clinics, and 0.030 (0.024-0.048) for dental clinics. In 51.9% of hospitals, the man-days of monthly HIE use was 0; in 26.8% of hospitals, it was between 1 and 10. In 3.0% of hospitals, it was 100 or more. The monthly HIE usage rate in medical institutions was 0.511(0.487-0.529) for the highest HIE and 0.109 (0.0927-0.117) for the lowest. The proportion of HIE usage frequency by occupation is complex, and no consistent trends can be discerned.

CONCLUSIONS

This study suggests that HIEs in Japan are not fully utilized by most healthcare workers in daily clinical practice, even if the number of participating facilities and patients is large. The monthly utilization rate of HIEs varies greatly by facility type or HIE. We need more detailed and cross-sectional research using log data analysis on HIE use's success and failure factors.
Mathematical Model of Freezing of Rocks Saturated With Salt Solution Taking Into Account the Influence of Osmosis
Authors: Ramazanov Mukamay , Bulgakova Natal'ya , Lobkovsky Leopold
Published: January 2024

The paper presents a mathematical model of rocks freezing saturated with salt solution under impact of osmotic force. Osmosis is related to the salt concentration gradient, which is characteristic for solutions, and it is a powerful mechanism for the movement of solutions in poorly permeable porous media. A mathematical criterion for the formation of closed “pockets” with brines (cryopags) in frozen rocks has been obtained. This criterion is shown to be significantly depends on the osmosis coefficient. The model includes three layers of a porous medium saturated, respectively, with ice, ice and solution, and salt solution only. A special case was studied when there is only a second layer with a movable boundary, on which a phase transition from the second layer to the third one occurs. The investigated layer is saturated with a salt solution and ice in thermodynamic equilibrium. Other layers are replaced by boundary conditions. An approximate analytical solution of the problem is found in a self-similar formulation. The nature of the influence of osmotic force on the freezing process of rocks saturated with solution is shown. The characteristic patterns associated with the considered process are revealed. One of the features of the osmosis influence is the fact that it can cause the movement (migration) of the solution in the direction of increasing pressure, i.e. in the direction opposite to the driving force caused by the pressure gradient.
Digital Currencies and the Nigerian Economy: Evidence from Selected Coins
Authors: ADEMOSU Solomon T. , AYODELE Thomas D.
Published: January 2024

This study emphasizes the implication of dynamic connection between digital currency and Nigerian economic growth rate by focusing attention on Bitcoin, Ethereum and Lite coin with respect to their returns and volatility from 2010Q4 to 2022Q3. As a way to have a robust estimation, we model our analysis using ARDL model and granger causality test. This model is rather useful to have both short and long run estimations. Importantly the study’s outcome conforms with the fundamentals. The trend analysis suggest that the country’s exchange rate move in line with digital currency activities while at the same time signifies some implication on the growth rate of the Nigerian economy. While lower returns for Bitcoin and Litecoin increase growth rate, the return for Ethereum rather move in the same direction as the growth rate. This indeed suggests that most Nigerians into digital currency activities often engage in portfolio diversification among available coins. The study further found that low volatility in the market will raise (significantly especially for Ethereum) growth rate of the economy while causal implication run from returns and volatilities of these coins to growth and exchange rates. Indeed, the findings have important policy implication for the Nigerian economy.

Authors: Chen Dan
Published: January 2024

In recent years, the development of technologies such as big data, artificial intelligence, and the Internet of Things has drastically changed the architectural market, raising the demands on architects by enterprises and institutions. The traditional teaching model of architecture majors struggles to meet the market's demand for professionally applied talents, necessitating reform. With the introduction of the new engineering talent training model by the Ministry of Education, the goal of educating students has shifted from a focus on theory and professional techniques to nurturing engineering talents with innovative spirit and practical skills. The cultivation of these qualities requires profound contemplation by architectural educators on how to train architectural talents who can meet societal needs, and put these ideas into action. Based on the concept of new engineering construction, this article first analyzes the problems students face in actual teaching and practical work. It then proposes suggestions for teaching reform specific to Architectural Design V, applying these reform measures to the education of senior students. This approach is beneficial in enhancing students' professional design abilities and innovative thinking, thereby improving the quality of applied talent training and teaching standards. This holds significant guidance value for the practical teaching reform of architectural courses.
