Published: October 2023

The advent of the digital era has spurred numerous companies to employ marketing communications strategies. Such endeavours serve as a means to influence and remind consumers about the array of products or services they offer. A particularly prominent approach for companies entails utilising digital marketing communications. In this context, the focus extends beyond mere product promotion; instead, it centres on disseminating valuable, pertinent, and consistent content to captivate and retain consumers. For this study, Instagram has been selected as the platform of interest due to its prevalence as a content distribution channel. The primary objective of this research is to explore the practices of digital marketing communications employed by the Something brand through its Instagram presence. To this end, the Krippendorff content analysis method has been applied to discern the nature of posts related to digital marketing communications on the official Instagram account @somethincofficial. The analysis was conducted on posts from 1 August 2022 to 31 October 2022. The study's findings reveal that Somethinc's digital marketing communication practices on Instagram predominantly revolve around informative and reminding advertising. These strategies are pivotal in engaging the audience and reinforcing brand awareness on the platform.

Published: October 2023

The increasing use of the internet has created a vast amount of digital information and it is expanding extremely fast. Therefore, Information retrieval becomes a challenging task to fetch relevant information for users. The aim of this paper was to examine and evaluate the performance of the Information retrieval system through eight experiments to test all the features that can be used in a vector space model. These experiments were compared to show the best and the worst implemented features. The features are represented by applying (tf.idf, stop words, stemming), (tf.idf, No- stop words, stemming), (tf.idf, No- stop words, No-stemming), (tf.idf, stop words, No-stemming), (tf, stop words, stemming), (tf, No- stop words, stemming), (tf, No- stop words, No-stemming), (tf, stop words, No-stemming). Results showed that using stop words, stemming approach, and tf.idf improve the performance of the system. However, when tf was used without using stop words and stemming approaches the performance of the system is declined. In addition, results showed that stop words have a significant effect on the system while the stemming approach has no noticeable effect particularly with tf.
Indonesian Omnichannel Banking: How Far Do Governing Laws Protect Customer's Data Privacy
Authors: Munzil Fontian , Zakaria Nadisah
Published: October 2023

In the digital transformation era, banks have been working to implement a digital strategy that will lead to lower costs, better service, higher profitability, and the desired level of customer satisfaction. Utilising marketing technology for consumer engagement is essential to bringing in more customers without increasing costs. Omnichannel is the marketing strategy that offers more services to customers by having them interact with it across all available physical and digital channels at any time, resulting in higher customer satisfaction and loyalty. Customer data is significant information that may be used at any stage of the digital marketing process. The Protection of Personal Data Act of 2022 and the Act of Development and Strengthening of the Financial Sector of 2023 govern consumer data protection at all stages of marketing activities, including data processing, profiling, and collaboration with other organisations. This study reviews how far the governing laws can protect consumer private data in utilisation in the company's digital marketing program to boost utilisation of the company's omnichannel approach. The study discovered that governing laws can protect the customer's private data in the banking omnichannel approach. Customer data are governed clearly and strongly by the regulations at all marketing program phases that could potentially be exploited, so both laws will be able to prevent illegal activities of customer data optimally in the future. Lastly, customer approval is critical for the Bank's use of all customer data.

Rural Teacher Competencies: An International Comparative Study on the Territorial Dimension of Rural Schools
Authors: Lorenzo Lacruz Juan , Buscá Donet Francesc , Abós Olivares Pilar
Published: October 2023

This article presents the results of a descriptive study carried out within the framework of the FOPROMAR project, obtained after administering a questionnaire regarding competences related to the territorial dimension of rural schools among teachers working in rural schools in Spain (Aragon and Catalonia), France (Aquitaine) and Portugal (Alto Alentejo). The questionnaire included three parts (professional profile, competences on the territorial dimension of the school and knowledge about the territory), but only the results referring to the competences section are presented, showing the level of relevance and the degree of mastery that teachers express in relation to these competences. According to the results, the competences with the greatest mastery are those referring to the design and development of programmes, followed by professional competences and school-community relations. This order is also found in the assessment carried out, indicating that they are more valued than mastered. One of the conclusions is the need to reinforce competences not included in training plans, but considered more necessary and important for working in rural schools.
What is the Role of Science in Post-Socialist Education and Society? Insights from a Survey of Preschool Teachers from Croatia, Serbia and Slovenia
Authors: Ivković Hodžić Željka , Vujičić Lidija , Boneta Željko
Published: October 2023

The paper presents the results of a survey conducted among preschool teachers in Croatia, Serbia and Slovenia, the aim of which was to investigate the attitudes of the participants towards the role of science in education and society. Recent global trends in economic development have introduced new educational concepts in national curricula worldwide, one of which is scientific literacy. Preschool teachers have been encouraged to introduce scientific activities with children into their practice and adopt a new outlook on the role of the natural sciences in education. Social change within the post-socialist context implied that adopting the new outlook required a value shift for all members of the education community. We therefore wanted to explore whether this process was actually taking place, and whether it was impacting the perception of science amongst preschool teachers. We applied Inglehart’s modernisation theory of materialist and postmaterialist values. The results showed that preschool teachers in all three countries were inclined to a postmaterialist view of science, but that it was possible to distinguish between two value-orientations, which we named “post-materialism” and the “materialist image of the child”. Older teachers accepted the “materialist image of the child” more than younger teachers, confirming a certain intergenerational value change, which we have interpreted as a shift from a collectivist to an individualistic approach to education.

A theoretical study on the thymoquinone compound has been performed through two theoretical methods, DFT/B3LYP and HF with 6-31G, 6-31G(d, p) and 6-31++G(d, p) basis sets using Gaussian 09 program. Some theoretical properties, like vibrational and electronic properties especially UV-Vis and FT-IR spectra, of the title compound were analyzed and then compared with available experimental data. The calculated harmonic vibrational frequencies have been scaled with standard scaling factors 0.9 and 0.965 for HF and DFT/B3LYP, respectively and then compared with available experimental FT-IR spectrum. Furthermore, the statistical analysis was investigated to evaluate the performance of both the HF and DFT methods, including root mean square error (RMSE), mean absolute error (MAE) and mean percentage error (MPE). According to the assigned vibrational modes of the title compound, it could be concluded that the DFT/B3LYP method with 6-31++G(d, p) basis set had the best agreement with experimental data. UV-Vis absorption spectra, excitation energies, maximum absorption wavelength, electronic transitions and oscillator strengths of the title compound were calculated by time dependent density functional theory ( TD-DFT) method using the same basis set and compared with available experimental data. The results showed the best performer was HF method with 6-31G basis set.
Evaluation of the Influence of Body Mass Index and Signal-to-Noise Ratio on the PET/CT Image Quality in Iraqi Patients with Liver Cancer
Authors: Hade Aya B. , Essa Samar I.
Published: October 2023

Image quality has been estimated and predicted using the signal to noise ratio (SNR). The purpose of this study is to investigate the relationships between body mass index (BMI) and SNR measurements in PET imaging using patient studies with liver cancer. Three groups of 59 patients (24 males and 35 females) were divided according to BMI. After intravenous injection of 0.1 mCi of 18F-FDG per kilogram of body weight, PET emission scans were acquired for (1, 1.5, and 3) min/bed position according to the weight of patient. Because liver is an organ of homogenous metabolism, five region of interest (ROI) were made at the same location, five successive slices of the PET/CT scans to determine the mean uptake (signal) values and its standard deviation. We obtained the liver's Signal-to-Noise Ratio from the ratio of both. Weight, height, SNR, and Body Mass Index were determined using a spreadsheet, and graphs were created to show the relationship between these variables. The graphs demonstrated that SNR decreases when BMI increases and that, despite an increase in injection dose, SNR also decreases. This is because heavier individuals take higher doses and, according to reports, have lower SNR. These results show that, despite receiving larger FDG doses, heavier patients' images, as measured by SNR, are of lower quality than thinner patients' images.
On Accounting for Own Fields of Emitters when Describing Generation Modes
Authors: Kuklin Volodymyr M. , Poklonskiy Eugen V.
Published: October 2023

The paper discusses three different modes of electromagnetic field generation by an ensemble of oscillators placed at the radiation wavelength in the one-dimensional case. The excitation of the resonator field is considered, which, as a rule, is determined by the geometry of the system, with and without taking into account the eigenfields of the emitters. The superradiance regime of the same ensemble of oscillators is also analyzed. In fact, superradiance is formed due to the emitters' own fields even in the absence of a resonator. It is noted that the maximum achievable amplitudes of induced fields both in the superradiance regime and in the regime of excitation of the resonator field are comparable. This makes us think about the role of the self-fields of emitters in electronic devices. It is shown that in describing the resonator excitation mode, in addition to the resonator field, it is also necessary to take into account the sum of the natural fields of the emitters in the active zone. Synchronization of emitters leads not only to an increase in the resonator field, but also, as in the superradiance regime, it significantly increases the amplitude of the sum of the oscillator fields. It is shown that in the practically interesting case of open systems (dissipative generation modes), taking into account the eigenfields of the emitters significantly reduces the characteristic time for the development of the generation process and increases the maximum achievable oscillation amplitude. This account also changes the conditions for achieving the maximum energy flow from the system. This can change the operating point of the generation process, which is determined by the requirement for the maximum rate of energy output from the system.

Published: October 2023

Among the various fluorescent probes currently used for biomedical and biochemical studies, significant attention attracts cyanine dyes possessing advantageous properties upon their complexation with biomolecules, particularly nucleic acids. Given the wide range of cyanine applications in DNA studies, a better understanding of their binding mode and intermolecular interactions governing dye-DNA complexation would facilitate the synthesis of new molecular probes of the cyanine family with optimized properties and would be led to the development of new cyanine-based strategies for nucleic acid detection and characterization. In the present study molecular docking techniques have been employed to evaluate the mode of interaction between one representative of monomethines (AK12-17), three trimethines (AK3-1, AK3-3, AK3-5), three pentamethines (AK5-1, AK5-3, AK5-9) and one heptamethine (AK7-6) cyanine dyes and B–DNA dodecamer d(CGCGAATTCGCG)2 (PDB ID: 1BNA). The molecular docking studies indicate that: i) all cyanines under study (excepting AK5-9 and AK7-6) form the most stable dye-DNA complexes with the minor groove of double-stranded DNA; ii) cyanines AK5-9 and AK7-6 interact with the major groove of the DNA on the basis of their more extended structure and higher lipophilicity in comparison with other dyes; iii) cyanine dye binding is governed by the hydrophobic and Van der Waals interactions presumably with the nucleotide residues C9A, G10A (excepts AK3-1, AK3-5), A17B (excepts AK3-5, AK5-3) and A18B in the minor groove and the major groove residues С16B, A17B, A18B, C3A, G4A, A5A, A6A (AK5-9 and AK7-6); iv) all dyes under study (except AK3-1, AK3-5 and AK5-39 possess an affinity to adenine and cytosine residues, whereas AK3-1, AK3-5 and AK5-3 also interact with thymine residues of the double-stranded DNA.

The semiclassical approach involved the use of the WKB approximation to describe the relative motion between the projectile and target nuclei, and the Continuum Discretized Coupled Channel (CDCC) method of Alder-Winther (AW) to describe the intrinsic motion of the nuclei. The importance of the neutron and the proton transfer and exchange on the calculations of Pfus, Dfus, and σfus for the studied systems. The results showed that the consideration of the coupling-channel calculations for quantum mechanics and a semi-classical approach, are very important to be considered specifically around and below the Coulomb barrier. The results were compared with the measured data and found in reasonable agreement.

In this research, the effect of changing the potential depth V0 on the Quasi-elastic scattering and barrier distribution calculations have been studied using Wood-Saxon (WS) potential for 16O+160Gd and 12C+197Au systems. The chi square (χ2) is applied to compare the best fitted value of the diffuseness parameter between the theoretical calculations and the experimental data. The diffuseness parameter which used in this work is to be at standard value 0.63. The χ2 was applied to most suitable the better fitted value of the potential depth V0. According to the results, we noticed that some systems achieved a good match between the theoretical calculations and experimental data of Quasi-elastic scattering (dσqel/dσR) and the distribution calculations at the standard value of the potential depth or at a value lower than the standard value and no match was achieved at a value greater than the standard value of the potential depth V0. We conclude that the values of quasi-elastic scattering values increase when the value of potential depth decreases.

Three-nucleon systems are essential for the investigation of many-body forces in nuclear physics. Well-grounded parametrization of their vertex functions with further application for the calculation of cross-sections in nonlocal QED approach provides the ground for investigation of the variety of multi-particle systems. In present paper we describe the process of parametrization of two-particle photo-breakup amplitudes of three-nucleon systems (3H, 3He). We provide the general description of the wave function construction for three-nucleon systems as well as the parametrization of their vertex functions accounting two- and three-nucleon interactions based on meson exchange current formalism. In our calculations we account first and second order one-pion exchange terms and the term related to the exchange of ω and ρ mesons. The three-nucleon interaction potential is given as a sum of attraction (two-pion exchange) term andappropriate repulsive part. Based on the variational ”Urbana + Model VII” amplitudes we provide the results for energy dependence of differential cross-section of 3He(γ, p)d reaction at proton angle θ = 90◦ from the threshold up to Eγ = 40 MeV and compare theoretical predictions with the available experimental data. The investigation is also provided for angular cross-section distributions at high photon energies (Eγ = 305 ± 5 MeV; 365 ± 5 MeV; 450 ± 10 MeV and 675 ± 50 MeV). Correct description of 3H, 3He photo-disintegration processes in a unified approach based on the gauge nature of the electromagnetic field implies application of this model for other multi-particle systems.

Objetivo.

Analisar a distribuição espaço-temporal e os fatores associados à mortalidade por doenças tropicais negligenciadas (DTNs) no Brasil de 2000 a 2019.

MÉtodo.

Estudo ecológico que analisou os óbitos por DTNs registrados no Sistema de Informação sobre Mortalidade (SIM). Para a análise temporal, utilizou-se o método joinpoint. A dependência espacial foi analisada pelos índices de Moran global e local e Getis-Ord Gi*. Quatro modelos de regressão não espacial e espacial foram usados para identificar fatores associados ao óbito.

Resultados.

A taxa média de mortalidade por DTNs no Brasil foi de 3,32 óbitos/100 000 habitantes no período considerado, com a maior taxa (8,68 óbitos/100 000 habitantes) observada no Centro-Oeste. As causas mais prevalentes de morte foram doença de Chagas (n = 94 781; 74,9%) e esquistossomose (n = 10 271; 8,1%). Houve redução de 1,24% (IC95% = -1,6; - 0,9; P < 0,001) ao ano da mortalidade por DTNs no Brasil. Observou-se padrão alto/alto de distribuição espacial e hotspots em municípios dos estados de Goiás, Minas Gerais, Bahia, Tocantins e Piauí. Os indicadores “população em domicílios com densidade > 2 habitantes por dormitório” (β = -0,07; P = 0,00) e “índice de desenvolvimento humano municipal” (β = -3,36; P = 0,08) associaram-se negativamente ao desfecho, enquanto o indicador “índice de vulnerabilidade social” (β = 2,74; P = 0,05) associou-se positivamente ao desfecho.

Conclusão.

Quanto menor o desenvolvimento humano e maior a vulnerabilidade social, maior é a mortalidade por DTNs, o que deve direcionar as ações de prevenção e controle das DTNs.

Ese artículo presenta la experiencia del diálogo político sanitario en enfermería desarrollado en Uruguay en el 2021, con base en la teoría del cambio. Se realizaron cuatro mesas de trabajo, con participación de 725 personas. Los puntos discutidos incluyeron: que existe un déficit de enfermeros licenciados para el desarrollo de los programas y para la cobertura de las funciones en todos los niveles de la atención a salud; la falta de visibilidad del impacto asistencial de las actividades desarrolladas; los recursos financieros insuficientes para la formación de grado y posgrado y la baja integración de los enfermeros en equipos de gestión y en espacios políticos de toma de decisiones en el país. Los participantes manifestaron la necesidad de implementar el plan nacional de desarrollo de la enfermería con los objetivos de que el país: disminuya el déficit de profesionales; invierta en la creación de cargos para satisfacer la demanda de cuidados profesionales; mejore las dotaciones de personal en los servicios en todos los niveles de atención; mejore las condiciones de trabajo; genere nuevos espacios de inserción de enfermeros ampliando su rol, mediante capacitación de posgrado y mejore continuamente la calidad de la formación. Los participantes hicierón hincapié en la necesidad de aumentar la coordinación intersectorial en los ámbitos de la gobernanza, la regulación y la gestión, y de acelerar los esfuerzos para aumentar la inversión en los profesionales de salud en Uruguay.
Enhancing Speaking Skill By Utilizing Podcast Material for Teenager Learners

Published: October 2023

Speaking is a form of practicing how to communicate ideas. The students can convey their intentions by speaking. Many high school students struggled to articulate their thoughts. Their low vocabulary, pronunciation, and grammar skills are what cause it. The teacher employed podcast resources in the teaching-learning process to address these issues. The instructor went over the basic grammar to put it into practice. In order to make it stick in their minds, the teacher instructed the student to look for the corresponding grammar in the transcript. Then, in order to expand their vocabulary, the student translate it. To improve the students' listening abilities, an audio recording was employed. The transcript was then read aloud. The students' newly acquired information is put to use in the text and audio descriptions of the images. The students took a pre-test before beginning this treatment, and they finished a post-test at the conclusion of it. A mixed-method approach was used to analyze the data that was found. It may be inferred that using podcast content improved the students' speaking proficiency. This kind of research can be used byteachers to teach relevant subjects. It also motivates other scholars to conduct deeper investigation.
