M-commerce: New Business Opportunities in the Jewellery Industry
Authors: Jain Dr. Neeru , Agrawal Ms. Shipra
Published: November 2023

Mobile phones, or more accurately, smartphones, have revolutionized the diamond industry. To gain a competitive edge in India, diamond and jewelry producers, master diamond cutters, and graduate gemmologists specializing in diamonds are using M-commerce to deliver novel customer service choices to their clientele.Electronic commerce, also known as E-commerce, has revolutionized the way people do business. Through electronic systems such as the Internet and other computer networks, traders may buy and sell goods from anywhere in the globe. Many Indian diamantaires and jewellery manufacturers adapted to this approach and profited as a result. Mobile commerce appears to be next on the agenda. M-commerce, or mobile commerce, is billed as the next generation of wireless Ecommerce that eliminates the need for wires and plug-in devices. Handheld gadgets such as mobile phones or Personal Digital Assistants can be used to undertake financial and promotional activities (PDAs).Although not everyone will be interested in M-commerce in the next years, it is expected to develop significantly as more advanced wireless handheld accessories become available. Because it has a global customer, the Indian diamond sector is accepting it more quickly. To fully benefit from M-commerce, diamantaires and jewelry manufacturers should educate themselves on the subject so that they can have the necessary information and implement it in their businesses as needed.
Conceptual Framework of Adoption and Implementation of Technological Challenges – A Road towards Sustainable Development
Authors: Dr. M. Selvaraj
Published: November 2023

As we all know that nothing can be produced without the involvement of factors of production. However, the involvement of intensification of various factors of production differs from product to product, region to region and firm to firm around the world. In this regard, without any second thought or opinion that technology is holding the driver's seat in economics, the road takes forward. Nothing is so important around the world that it is not giving any significant efficient contributions to the respective sectors, industries and firms in a state. Predominantly, technology allows progress toward efficient production and better goods and services. Nonetheless, in reality, the advancement of technological progress used is very complex, especially in highly populated developing countries like India with respect to policy implications and the decision-making process of the firms or the industry. Since, the bilateral linkage is observed by technological advancement with different variables like education, socio-economic growth, innovation, production and turnover ratio and so on. But, the likelihood of impact on reduction in the demand for labour force, widening of inequality in the distribution of wealth among the people and social responsibility needs to be ensured for the welfare by the regulators are also not to be neglected. The advancement of technologies and adoption of the same on the one side increases the flow of knowledge expansion, cooperation among the investors improves emerging businesses around the world. On the other side, the fabrication and challenges on multiplication of various inventive activities of the corporate world like automated systems, big data, development of information and communication technologies, artificial intelligence, patient, recipes, protocol, routine instructions and manuals also become inevitable to sustainable development. This paper is intended to review the challenges of adoption and implications of technological advancement toward sustainable socio-economic growth.

Práticas e percepções de ciclistas durante a pandemia de covid-19. Resultados de uma pesquisa com ciclistas na cidade de São Paulo, Brasil
Authors: Mascolli Maria Antonietta
Published: November 2023

RESUMO

Trata-se de um estudo transversal, descritivo, que entrevistou 340 ciclistas no município de São Paulo, Brasil, por meio de um questionário google form. Esta pesquisa foi realizada entre fevereiro e março de 2021 e investiga como a pandemia mudou os hábitos de quem utiliza a bicicleta, e de que forma estas práticas foram alteradas. Os ciclistas foram recrutados inicialmente a partir do ‘Projeto Pedal’ e a seguir pela metodologia bola de neve. Os autores concluem que a bicicleta foi utilizada de modo tático, tanto para evitar aglomerações e manter o isolamento social quanto para praticar exercício físico quando outros locais para a atividade esportiva estavam interditados. A circulação ocorreu majoritariamente na região central da cidade, de classe média e alta e com maior infraestrutura cicloviária. A proporção daqueles que aumentaram ou mantiveram o uso da bicicleta é semelhante àquela que diminuiu, com alteração nas motivações para os deslocamentos.

Populist Radical Right Parties and the Rhetoric of Emotions.
The Slovak Case Study
Authors: Gazarek Anton , Uhrecký Branislav
Published: November 2023

This article analyses the emotional rhetoric of the populist radical right parties in Slovakia - the Slovak National Party (SNS) and the People's Party Our Slovakia (ĽSNS) - in their 2016 and 2020 election manifestos. Emotional rhetoric, or pathos, consists of emotional appeals, and this article looks specifically at four discrete appeals to emotions: retrospective anger and enthusiasm; and prospective fear and hope, and connects these emotional appeals with topics according to their relevance. This research utilises qualitative content analysis drawing categories from the field of political psychology. Unexpectedly, it is found that positive emotional appeals are generally more common than negative ones in the election manifestos of the populist radical right. The second finding is that populist radical right parties with government experience apply a very different strategy in their emotional rhetoric. The more extreme ĽSNS, without government experience, relies more on the negative emotional appeal of anger, and SNS, with extensive government experience, relies on the positive emotional appeals of hope and enthusiasm. Furthermore, these cases confirm the hypothesis that a populist radical right party that uses more appeals to anger has greater success in general elections.
Population Pharmacokinetic Models (PopPK) and Their Application in Personalizing Treatment Dosing of Factor VIII in Adult Patients with Hemophilia
Authors: Juárez-Hernández José Eduardo , Castañeda-Hernández Gilberto , Majluf-Cruz Abraham
Published: November 2023

The “one dose works for all” paradigm is the most frequently used approach for drug administration. It involves pharmaceutical companies obtaining safety and efficacy data on drugs in a particular population and recommending a dose to achieve the therapeutic window. While this approach is helpful for medications with a wide therapeutic window, it fails to account for patient variability. Disregarding this variability may result in therapeutic failure due to adverse effects or lack of efficacy for drugs with a narrow therapeutic window. Population pharmacokinetic (PopPK) models offer a crucial tool in advancing personalized medicine. It is necessary to move beyond previous paradigms and adopt computer programs and tools that aid in developing therapeutics to fulfill patients’ specific needs. In the case of diseases where quick and maintained control is essential (e.g., hemophilia, epilepsy, pain management), popPK models, paired with user - friendly user interfaces (e.g., myPKFit) provide a powerful tool that has the potential to improve the patient’s quality of life.
EEG-Based Effective Connectivity Analysis for Attention Deficit Hyperactivity Disorder Detection Using Color-Coded Granger-Causality Images and Custom Convolutional Neural Network
Authors: Abedinzadeh Torghabeh Farhad , Modaresnia Yeganeh , Hosseini Seyyed Abed
Published: November 2023

Background: Attention deficit hyperactivity disorder (ADHD) is prevalent worldwide, affecting approximately 8-12% of children. Early detection and effective treatment of ADHD are crucial for improving academic, social, and emotional outcomes. Despite numerous studies on ADHD detection, existing models still lack accuracy distinguishing between ADHD and healthy control (HC) children. Methods: This study introduces an innovative methodology that utilizes granger causality (GC), a well-established brain connectivity analysis technique, to reduce the required EEG electrodes. We computed GC indexes (GCI) for the entire brain and specific brain regions, known as regional GCI, across different frequency bands. Subsequently, these GCIs were transformed into color-coded images and fed into a custom-developed 11-layer convolutional neural network. Results: The proposed model is evaluated through a five-fold cross-validation, achieving the highest accuracy of 99.80% in the gamma frequency band for the entire brain and an accuracy of 98.50% in distinguishing the theta frequency band of the right hemisphere of ADHD and HC children by only using eight electrodes. Conclusion: The proposed framework provides a powerful automated tool for accurately classifying ADHD and HC children. The study’s outcome demonstrates that the innovative proposed methodology utilizing GCI and a custom-developed convolutional neural network can significantly improve ADHD detection accuracy, improving affected children’s overall quality of life.

Published: November 2023

Background: COVID-19 vaccination is one of the most successful ways to control the ongoing pandemic and prevent severe diseases, hospitalization, and death. Current evidence suggests COVID-19 vaccine hesitancy (a delay in accepting or rejecting the vaccine despite the availability of vaccination services) is a barrier to successful vaccination programs worldwide. This study aimed to explore the underlying factors associated with COVID-19 vaccine hesitancy among the Iranian population. Methods: This qualitative content analysis study was conducted using in-depth semi-structured interviews. A total of 32 Iranian participants with diverse ethnicity, language, age, and gender were selected through purposive sampling. Interviews were analyzed using Graneheim and Lundman’s qualitative content analysis method. MAXQDA software was used for data analysis. Results: Three themes and eight subthemes emerged from the qualitative interviews. Individual underlying factors included knowledge, beliefs, and the fear of COVID-19 infection. Social factors included social media, the health system, and governance. Institutional factors included vaccine opponents and health experts that fueled COVID-19 vaccine hesitancy and refusal among the participants. Conclusion: Poor knowledge, misbelief, and fear were the most commonly reported causes of vaccine hesitancy and refusal among Iranians. Therefore, targeted interventions are recommended to address misinformation among the Iranian population.

Authors: Heidarpoor Peigham , Hadyan Soheyla
Published: November 2023

Background: Sedentary lifestyle is regarded as one of the main risk factors for obesity and chronic diseases. As schools provide students with important opportunities for physical activity, their closure, prompted by the COVID-19 pandemic, had a detrimental impact on vulnerable populations, particularly youth and school students. Therefore, this study aimed to investigate the effect of virtual physical education on students’ quality of life during the COVID-19 pandemic. Methods: This community trial was conducted with an experimental and a control group. For this purpose, 300 students aged 13 to 15 years, selected among students of the 1st year of high school, were selected from the four education districts of the urban areas of Karaj city in the year 2020 using a cluster sampling method. The selected students were randomly assigned to the two groups of intervention and control, each with 150 people. There was no difference between the two groups in terms of inclusion criteria and demographic characteristics. Following group assignment, the intervention group received virtual physical education for eight 30-minute sessions, one session each week. All subjects completed the Physical Activity and Quality of Life Questionnaires before and after the training. The data were analyzed with SPSS software version 20, using the chi-square test, paired t-test, and independent t-test. Results: The mean and standard deviation of the scores in almost all areas of quality of life (both physical activity and mental health) in the intervention group had a significant improvement after the training courses (P<0.05). After training, the mean scores of quality of life in the virtual education group were significantly greater than control group (P<0.05). Conclusion: The virtual school-based physical activity intervention had positive effects on children’s psychological and psychological wellbeing. The online educational method could provide customizable physical education learning activities as a suitable step in promoting physical activity engagement for different groups of students.

Published: November 2023

Background: In recent years, there has been a great deal of attention to the subject of happiness. Happiness increases job and academic performance and maintains emotional, mental, and physical health. The aim of this study was to determine the status of happiness and its effective factors among students of the Department of Public Health at Jundishapur University of Medical Sciences, Ahvaz, Iran, in 2021. Methods: This study was a descriptive-analytical cross-sectional study. The information of 202 students were collected by census method. The Standard Oxford Happiness Questionnaire (online) was used to collect information. One-way ANOVA and chi-square test were used for analysis of data. Results: The average age of the students was 25±6.05 years, 79.7% were female, 80.7% were unmarried, and 55% were non-dormitory students. According to the data, 4.5% of the students had low levels of happiness and 19.8% and 75.8% had average and high happiness levels. The results showed that there was no statistically significant relationship between the state of happiness and the variables of age, academic grade, gender, level of education, marital status, and place of residence of the students (P value>0.05). However, a statistically significant relationship was observed between students’ happiness and their personal health (P value<0.001). Conclusion: The results of this study showed that the state of happiness among students of the Department of Public Health at Ahvaz University of Medical Sciences was good. As some students had a lower level of happiness, it seems necessary that more attention be given to these students.

Authors: Dehghani Ghanatghestani Mohsen
Published: November 2023

Background: Radon is a major source of natural radiation in water, soil, and air. Natural sources of radiation are major contributors to the radiation humans and other living beings receive. Methods: This cross-sectional study was conducted on drinking water sources of three cities and 18 villages of Roudan county in 2021. The measurement of radon concentration in the collected samples was performed using the RAD7 device. Results: In the studied water sources, the highest and lowest radon concentrations were 11.00±2.09 and 0.95±0.23 kBq/m3 , respectively. The average radon concentration was 4.98±0.76 Bq/L which was lower than 11 Bq/L (the EPA level recommended for drinking water). The mean annual effective dose of radon, due to direct and continuous water intake for adults and children was 48.01±11.56 and 65.86±15.86 µSv/y, respectively. Conclusion: The results of this study showed that radon concentrations in two regions of Roudan county were higher than the allowed World Health Organization (WHO) concentration and people who normally use these resources for drinking during the year are exposed to abnormal radiation levels.

Peculiarities of the state of the hard tissue of the temporary teeth in 6-years-old children
Authors: Kotelban A.V.
Published: November 2023

Literary data show that caries is the most common dental nosology in the world. After conducting epidemiological studies of our region, we established a high incidence of caries in children aged 6 according to WHO criteria. In this regard, we set ourselves the aim of assessing the peculiarities of the state of hard tissues of temporary teeth in children living in different regions of Bukovyna. To solve the aim, we examined 306 children in 13 schools of the Chernivtsi region. The following observation groups were selected: Group I – 93 children aged 6 years living in Vyzhnytskyi District, Group II – 119 children aged 6 years living in Chernivtsi District and Subgroup III – 94 children aged 6 years living in Dniester District. We analyzed the prevalence, intensity of caries of temporary teeth, level of intensity, ICDAS1-6 in different regions of Bukovyna. The degree of probability of the obtained results was statistically assessed. The prevalence of caries of temporary teeth in 6-year-old children is high in all regions: 93.54% in Vyzhnytskyi, 93.61% in Dnistrovskyi and 92.43% in Chernivtsi districts. The analysis of the intensity of caries showed that the highest values – in children of the Vyzhnytsky district (5.46±0.33) affected teeth, the lowest – in the examined children of the Dniester district – (5.05±0.28). The "d" component dominated the structure of the "dmf" index in all regions. It should be noted that the extracted teeth were from 1.59 to 4.39%. In all regions, the average level of intensity prevailed, but the share of children with a high level was also high: 39.78% in Vyzhnytskyi, 31.91% in Dniester and 30.25% in Chernivtsi districts. The lower second molar was most often affected, with a share of 26.53%. A combined lesion of several groups of teeth, in particular the upper and lower molars, as well as the upper frontal teeth that were present, is characteristic. Carious cavities were most often located on the masticatory (31.25%) and contact surfaces (51.52%). Enamel caries was most often diagnosed in 41.21% of cases, a third of all lesions (36.64%) were dentine caries, and a fifth part (22.13%) were caries at the stain stage. Therefore, the high incidence of caries in children in all districts of the Chernivtsi region indicates the need to study the regional risk factors for the development of caries in children for the further development of regionally adapted treatment and prevention programs.

Keywords: children, caries, complications of caries, prevalence, intensity, SIC-index.

Simultaneous multiple capture in the presence of evader's defenders
Authors: Blagodatskikh A.I. , Bannikov A.S.
Published: November 2023

We consider a conflict-controlled process with the participation of three types of controlled objects: a group of pursuers, an evader, a group of defenders of the evader. Dynamic and inertial capabilities of all controlled objects are the same. The evader and the group of defenders act cooperatively. The group of pursuers is the other side of the conflict. If the positions of the pursuer and the defender of the evader coincide then both players die and cease to participate in the conflict-controlled process. In a conflict controlled process multiple capture of an evader occurs when a given number of pursuers catch the evader, and capture moments may not coincide. If (not necessarily least) capture moments coincide then nonstrict simultaneous multiple capture of the evader occurs. Finally, simultaneous multiple capture of the evader occurs when least capture moments appear identical. We obtain necessary and sufficient conditions for simultaneous multiple capture of the evader in terms of initial positions of the participants and other parameters of the conflict-controlled process.
Control of a parabolic system with disturbances and a convex goal
Authors: Izmest'ev I.V. , Ukhobotov V.I.
Published: November 2023

The problem of controlling the heating process of a given number of rods by changing the temperatures at their left ends is considered. Temperatures at the right ends of the rods are formed by disturbances. The density functions of the internal heat sources of the rods are not known exactly, and only the boundaries of the range of their possible values are given. The goal of the choice of a control is to lead the vector of average temperatures of the rods at a fixed time to a convex terminal set. For this problem, necessary and sufficient conditions have been found that must be satisfied by the initial temperatures of the rods so that the goal can be achieved under any admissible realization of disturbances and density functions of internal heat sources. The case of a problem with a possible change in the dynamics of the controlled system is considered.
The differential game “Cossacks–robbers” on time scales
Authors: Mozhegova E.S. , Petrov N.N.
Published: November 2023

In finite-dimensional Euclidean space, we address the problem of simple pursuit of a group of evaders by a group of pursuers in a given time scale with equal opportunities for all participants. The set of controls of each participant is a sphere of unit radius with its center at the origin. The goal of the group of pursuers is to catch all evaders. The goal sets are the origin. The goal of the evaders is the opposite one, namely, for at least one evader to avoid capture. Conditions for solvability of the local and global problems of evasion and the upper and lower estimates of the minimal number of evaders avoiding a given number of pursuers from any initial positions are obtained.
Asymptotic expansion of the error of the numerical method for solving wave equation with functional delay
Authors: Pimenov V.G. , Tashirova E.E.
Published: November 2023

A wave equation with functional delay is considered. The problem is discretized. Constructions of the difference method with weights with piecewise linear interpolation are given. A basic method with weights with piecewise cubic interpolation is constructed. The order of the residual is studied without interpolation of the basic method, and the expansion coefficients of the residual with respect to time-steps and space-steps are written out. It is proved that the weighted method with piecewise cubic interpolation converges with order 2 in the energy norm. An equation is written for the main term of the asymptotic expansion of the global error of the basic method. Under certain assumptions, the validity of the application of the Richardson extrapolation procedure is substantiated, and the corresponding numerical method is constructed, that has the fourth order of convergence with respect to time-steps and space-steps. The validity of Runge's formulas for practical estimation of the error is proved. The results of numerical experiments on a test example are presented.
Eigenvalues and eigenfunctions of the perturbed non-Hermitian SSH Hamiltonian with PT symmetry
Authors: Tinyukova T.S. , Chuburin Yu.P.
Published: November 2023

In the paper we find near-zero eigenvalues (their physical meaning is the electron energy) and eigenfunctions describing the electronic states of the non-Hermitian SSH Hamiltonian for an infinite chain with PT symmetry, perturbed by a $\delta$-shaped potential. We prove that for a small non-Hermitian parameter there are two (generalized) eigenvalues of multiplicity one, and, in contrast to the Hermitian model, the corresponding (generalized) eigenfunctions depending on the parameters of the system can either increase exponentially (which corresponds to resonant, i.e., decaying states) or decrease exponentially (which corresponds to bound states) as $|n|\to\infty$.

Introduction: Soybean cultivation is inseparable from the attack of plant pests. Control of soybean pests, which generally use synthetic pesticides, negatively impacts food products, environmental health, and ecosystem sustainability.  Planting flowering plants around bunds can be useful in increasing the diversity of natural enemies because they can attract and serve as microhabitats for natural enemies. This research to obtain the effect of refugia treatment and soybean spacing on the diversity of natural enemies in soybean plantations. Methods: The study was designed in randomized block design, consisting of refugia and non-refugia treatments and plant spacing of 40 cm x 25 cm (J1) and 50 cm x 25 cm (J2), which was repeated three times. Sampling was carried out in the vegetative and generative phases, using yellow traps and pitfalls installed in the field for 24 hours. Results: The results showed that the most trapped natural enemy families were in the refugia treatment. The total number of trapped natural enemies was highest in the vegetative and generative phases, namely in the refugia and 2 spacing treatments (R-J2). The family of Braconidae order Hymenoptera and the group of parasitoids had the highest numbers in the refugia and non-refugia treatments. The value of the Diversity Index (H') in the refugia treatment and both plant spacings in the two growth phases was moderate, while in the non-refugia treatment, the two plant spacings and both growth phases were small and medium. Generally, the evenness index (D) value for all treatments is known to be small and medium. Conclusion: Refugia treatment and plant spacing affect the number of natural enemy populations, which is expected to suppress the development of pests in soybean cultivation.

STUDY OF DYSLIPIDEMIA IN ASSOCIATION WITH TOTAL ANTIOXIDANT STATUS IN PREECLAMPSIA.
Authors: Aruna P.
Published: November 2023

Introduction: Preeclampsia is a serious complication of the second half of pregnancy that occurs with a
frequency of 5-15%. Preeclampsia is an endothelial disease with a major involvement of lipid mediated
oxidative damage along with an imbalance between prooxidant production and antioxidant defenses. Aims and objectives:
To study the association of dyslipidemia with total antioxidant status in the form of Ferric reducing antioxidant power ( FRAP) in
preeclampsia. The present study was carried out for one year on pregnant women attending Materials and methods:
Obstetrics department as OP&IP at Narayana Medical College, Nellore.50 normal healthy pregnant women of > 20 weeks
gestation were selected as controls.50 diagnosed preeclampsia cases > 20 weeks of gestation and with urine protein
creatinine (P/C) ratio more than 0.3 were selected as cases. The cases were further divided into mild and severe. FBS, S.
Creatinine, Urine protein and creatinine, Total cholesterol, Triacylglycerol, HDL-C, LDL-C, Uric acid, FRAP were measured.
Results: In our study the decrease in (mean±S.D) values of TAS in PE was statistically signicant when compared to
controls(586.56 ±109.49 and 534.46 ±97.41,p Value=0.01). Total cholesterol, LDL-C and TAG levels were increased
signicantly in comparison to controls(p<0.001). The decrease in HDL-C was not statistically signicant(p=0.71). FRAP
correlated negatively with Total cholesterol in our study. The antioxidant levels are inversely Discussion and conclusion:
proportional to dyslipidemia. Elevated LDL levels undergo oxidation to form oxidized LDL, which is involved in inammation
and free radical generation. In order to counteract the free radicals generated, antioxidant levels decrease. Hence decreased
antioxidant status is associated with dyslipidemia, an important cardiovascular risk factor in preeclampsia.
OUTCOMES OF TOTAL PERICARDIECTOMY FOR CONSTRICTIVE PERICARDITIS- A SINGLE CENTRE EXPERIENCE OF 20 YEARS
Authors: Sanghavi Utkarsh , Jain Vartika , Bansal Vidur , Upadhyay Vinay
Published: November 2023

Background: Constrictive pericarditis (CP) consists of a spectrum of primary cardiac and noncardiac
conditions. It represents a form of severe diastolic heart failure (HF) which is usually secondary to a noncompliant pericardium. Our study was designed to evaluate immediate and short term outcomes of total pericardiectomy
clinically and echocardiographically. Through this study we aimed to analyze the short-term and mid-term outcomes of total
pericardiectomy using death and adverse events as end points. Between January 2001 and December 2020, a total of 166
patients with constrictive pericarditis underwent total pericardiectomy at our institute. Results: The mean age was 30.4±13.35
years. The mean post-operative CVP was 8.73±3.06 cm of H20. Histopathological results showed tuberculous pericarditis
86(51.82%) in patients, chronic constrictive pericarditis in 76(45.78%) patients, purulent pericarditis in 2(1.20%) patients and
viral pericarditis in 2(1.20%) patients. At the end of 12 months, 150(92.60%) patients were in NYHA class I and 12(7.40%) patients
were in NYHA class II. Conclusions: In a developing country like India, tuberculosis is still the most frequent cause of CP. Total
pericardiectomy with or without the use of CPB is the surgical treatment of choice and should be performed as early as possible
as it is associated with a lower mortality, early normalization of hemodynamics, less postoperative low cardiac output
syndrome, and better long-term survival.
EFFECTIVENESS OF AN AWARENESS PROGRAM ON KNOWLEDGE AND ATTITUDE REGARDING HUMAN MILK BANK AMONG ANTENATAL MOTHERS: A STUDY PROTOCOL
Authors: S. Rotkar Bhawna , K. Soni Anita
Published: November 2023

Background: Breast milk offers the ideal source of nutrition for the rst 6 months after birth and may
remain a part of an infant's diet. Many infants lack access to their mothers' own milk because of issues
related to the mother's illness death, abandonment, or infant illness. This lack of access to breast milk leaves infant more
vulnerable to disease, poor health, or death, especially when they are born preterm, have low birth weight or are severely
malnourished. A human milk bank screens donated milk and distributed the milk to infants in need. Objective: To assess the
effectiveness of an awareness program on knowledge and attitude regarding human milk bank among antenatal mothers in
selected hospitals. Methodology: A pre-experimental one group pre-test post-test design will be used. 73 antenatal mothers
will be selected by non-probability convenience sampling. The tool will consist self-structured knowledge questionaries and
attitude scale based on human milk bank. After pre-test and administering intervention on awareness program on human milk
bank, post-test will be conducted on 7th day. Content validity of questionnaire will be carried out by the experts of concerned
eld. Reliability of tool will be assessed by Cronbach's alpha value. The collected data will be analysed by using descriptive
and inferential statistics. Expected results: There may be signicant difference between pre-test and post-test knowledge and
attitude score regarding human milk bank among antenatal mothers. Limitation: This study will be delimited to selected
geographical areas. Conclusion: An awareness programme will be effective in improving knowledge and enhancing
favourable attitude regarding human milk bank among antenatal mothers and thus able to combat with the myths and
misconception regarding human milk donation and its acceptance.
Libri italiani di storia dell’arte all’estero: alcuni casi esemplari
Authors: Lacagnina Davide
Published: November 2023

L’italiano è da sempre la lingua franca della storia dell’arte. È raro imbattersi in storici dell’arte non italiani, in passato specialmente del Rinascimento e del Barocco, che non conoscano e parlino correntemente l’italiano: una condizione non solo relativa a uno specifico ambito di specializzazione, come è facile immaginare, ma anche un riconoscimento al prestigio di una disciplina che ha avuto storicamente in Italia uno dei suoi epicentri più importanti e vitali. Forse, anche per questo motivo, la fortuna del libro di storia dell’arte italiano può configurarsi come una piccola enclave all’interno della già ristretta circolazione internazionale della saggistica italiana, potendo di fatto gli specialisti del settore attingere direttamente, e senza particolari difficoltà, alle fonti in lingua originale.
Il paesaggio, il colore e il concetto. Su 'Un uomo tranquillo' (1952) di John Ford
Authors: Venzi Luca
Published: November 2023

Se chiedessimo a chi abbia appena visto, o visto almeno una volta, The Quiet Man (1952, Un uomo tranquillo), uno dei più celebri e più compiuti film non-western di John Ford, di indicare un singolo colore che nel film, splendidamente fotografato da Winton C. Hoch, gli sia parso dominante, quasi certamente questi risponderebbe il verde. A proposito di una presenza a suo dire eccessiva di quello stesso colore nelle immagini del film, evidentemente esagerando, si era del resto subito espresso lo stesso preoccupato presidente della Republic Pictures, Herbert Yates, quando, durante le riprese, visionava dagli Stati Uniti i rushes degli esterni che gli venivano inviati dall’Irlanda. Se, come ricorda Davis, Barbara Ford, figlia del regista e assistente montatrice (non accreditata) nel film, scriveva a suo padre che quanto lui e la sua troupe stavano realizzando le appariva magnifico e che l’Irlanda le sembrava un paese incantato, Yates, che aveva sempre nutrito forti dubbi sulla riuscita economica del film (sarebbe stato invece un enorme successo), osservava per contro, in un telegramma: «È tutto verde. Dite all’operatore di togliere il filtro verde».
