Some of the elderly feel themselves as marginalized in social life, because of a decline in physical and mental abilities. So not a few who experience depression because of their weak faith. Therefore, intensive religious training is needed for them. One of the institutions for the religious development of the elderly is a boarding school which specifically fosters the elderly. This study aims to analyze the elderly education program at the Daarul Fikri Integrated Islamic Boarding School  , Cikarang Bekasi, West Java about the basic values of the elderly pesantren; The purpose of the pesantren for the elderly; Characteristics of elderly Islamic boarding school students; Elderly boarding school program; Elderly islamic boarding school materials; Elderly boarding school method; Impact and evaluation of learning on religious understanding of the elderly. This study uses a qualitative approach with a descriptive method. The data collection technique uses observation, interview, and documentation techniques. Meanwhile, the analysis method goes through several stages, namely: data reduction, data presentation, and verification and drawing conclusions. The results of the study show: 1) The basic values of the elderly pesantren are support for the elderly to be able to live independently; 2) Islamic boarding schools for the elderly were established to accommodate the elderly who want to deepen their religious knowledge and seek inner peace; 3) Elderly students have special characteristics; 4) The elderly pesantren program is only held for one week for each generation; 5) The teaching materials in Islamic boarding schools for the elderly are the Qur'an, Islamic studies (Tawhid, Tafsir, Fiqh, akhlaq (islamic morality), tashihul worship, riyadloh / sports / natural meditation, worship guidance, dhikr, and morals. 6) The learning methods used in Islamic boarding schools for the elderly are discussions and lectures; 7) Elderly pesantren alumni feel an increase in religious insight and are diligent in establishing friendships. While the evaluation is focused on the implementation of the Islamic boarding school for the elderly.
Securing patient understanding in nurse–patient discharge discussions
Authors: Lehtimaja Inkeri
Published: April 2023

The aim of this study is to describe the communicative strategies nurses and patients use on a micro level to ensure patient understanding during discharge discussions. The data of the study consist of 16 videotaped discharge encounters (total duration 1 h 40 mins) between nurses and patients in Finland, which were analyzed using conversation analysis. The findings reveal that patients express understanding or troubles in understanding by subtle means, such as response particles. Nurses monitor patients’ reactions and adapt their subsequent actions to them, for instance by moving on to the next topic or by giving additional explanations. They also pursue expressions of understanding when needed, e.g., by prolonging the topic. This gives the patient time to react and more material to get a grip on the topic, thus facilitating displays of understanding. As a result, even if the discharge discussions consist mostly of information delivery that resembles a monological practice, the interaction is collaboratively constructed to secure patient understanding. A raised awareness of good practices already in use to secure understanding can contribute to further developing the guidelines for discharge education.
Generic characteristics of patients’ e-consultations with general practitioners

Published: April 2023

Electronic communication between patients and general practitioners (GPs), known as e-consultations, was introduced in Denmark as a cost-effective and convenient means for patients to access their GP and receive test results as well as answers to quick questions. Research on e-consultations internationally has found that patients are generally very positive, while doctors are more hesitant. Most studies of e-consultations have involved survey or interview methodologies, while studies of their content, form or language are limited. In this study, we address this gap by proposing that genre may be a productive concept for comprehending textual aspects of e-consultations. We explore the following two questions: (1) what are the generic characteristics of the e-consultation?; and (2) do e-consultations belong to the email genre? Based on an analysis of two Danish corpora of patients’ first turns in e-consultations with their GPs, we identify an underlying move structure: subject, opening, update, problem presentation, request, argumentation, closing. We argue that the e-consultation is an example of an email genre with identifiable conventions, which are both specific to the communicative function of e-consultations and aligned with generic features of emails.

Authors: Negrini Michele , Dalmaso Silvana Copetti
Published: April 2023

No telejornalismo brasileiro, muitas mortes de cunho criminal fazem parte da pauta cotidiana e casos de feminicídios são presença constante nas pautas telejornalísticas. No caso do Jornal Nacional, diversos crimes contra a mulher são abordados e têm significativo retrospecto diante do público. Desta forma, este artigo tem como objetivo fazer observações sobre as transformações do subgênero telejornal a partir de coberturas de feminicídio, com foco no Jornal Nacional. Vamos nos centrar na cobertura do JN das mortes de Daniella Perez, Eloá Pimentel e Tatiane Spitzner. E vamos tomar como base teórica a discussão de gênero televisivo com categoria cultural (MITTELL, 2001). A pesquisa tem caráter exploratório e observacional (GIL, 2008).
Os fundamentos de Eisenstein na montagem hollywoodiana de conflitos
Authors: Cassitas Cassia , Araujo Denize Correa
Published: April 2023

As premissas em que se basearam os investimentos em películas nos anos 1900-1930 parecem não terem sido superadas. Em uma releitura dos fundamentos da montagem de Eisenstein, investiga-se como a sequência de abertura do audiovisual Os 7 de Chicago (2020, Sorkin, BEL) utiliza técnicas de relacionamento de cenas para determinar a noção de tempo, ritmo, espacialidade, e movimentos gráficos. Cenas de noticiários de época são exibidas entre takes ficcionais, acredita-se, com o intuito de erigir um panorama histórico do sentimento de rejeição ao envio de soldados ao território vietnamita. Estuda-se aqui como os recursos da montagem são utilizados na elaboração de estratégias comunicacionais no intuito de instigar a reflexão e engajamento de diferentes públicos socio-culturais diante do conflito estabelecido.

ADAPTING AND TRANSFORMING ELT DURING AND POST COVID-19 ERA: PEOPLE, PLACES, AND PURPOSES
Authors: O'Boyle Aisling Marie , Samanhudi Udi
Published: April 2023

This article discusses the adaptations and possible transformations in ELT during and post COVID-19 times. The traditional focus for ELT is often a narrow perspective on teaching methodology, epitomized by the “3 Ps” in ELT- Present, Practice, Produce. We argue for a realignment of focus to “People, Places, and Purposes” in ELT and a focus on addressing social issues. We frame our discussion on the notion of being ultra-social and illustrate the creativity and adaptability in language use during the pandemic. Questioning the deeply held assumptions in ELT, we propose transformative action on social issues: speaking, shifting boundaries and sustainability.
CARTÃO DE VACINAÇÃO: IMPORTANTE INSTRUMENTO PARA INCENTIVAR A AUTONOMIA VACINAL DE ESTUDANTES
Authors: Paula Rayan Silva de , Monteiro Adriana Maira Ferreira Cardoso , Reis Deyse Almeida dos
Published: April 2023

Devido à diminuição da adesão à vacinação e fortalecidos pelo movimento antivacina, a cobertura vacinal mundial encontra-se em baixa e observa-se a recirculação de doenças outrora erradicadas. No Brasil, reconhecido por suas campanhas bem-sucedidas para vacinação de crianças e adolescentes, o documento válido para aferimento da cobertura vacinal é o cartão de vacinação (CV). Todavia, observa-se um distanciamento entre sujeitos e seus CVs, em que deterioração e extravios desse documento são recorrentes. Assim, o presente estudo propôs a aplicação de uma sequência didática envolvendo aspectos da vacinação, a fim de estimular a autonomia vacinal de estudantes de uma escola pública. Foram lecionadas aulas teóricas; exibidos episódios da animação “Cells at Work!”; e realizadas práticas com CVs dos próprios estudantes. Dentre os participantes, 88,24% e 82,35% mostraram, respectivamente, compreender que as células do sistema imunológico atuam por meio da fagocitose e da produção de anticorpos. 76,47% compreenderam que as vacinas conferem proteção individual e coletiva e 64,71% que o CV permite acompanhar o estado vacinal do indivíduo. Dentre as vacinas consultadas, a maioria era vacinada contra poliomielite, sarampo e Covid-19, sendo que para essa última vacina, todos haviam tomado pelo menos a primeira dose. Surpreendentemente, 78,57% afirmaram que já tinham tido acesso a seu CV, entretanto apenas 28,57% havia atentado às informações ali contidas. Por fim, 92,86% afirmaram que necessitam checar e atualizar o CV bem como se sentem impelidos a manter o CV em acordo com o calendário nacional de vacinação, evidenciando o despertar quanto à autonomia vacinal desses estudantes.
Origem e conceitos básicos de hibridização em química orgânica com aplicações no processo de biohidrogenação ruminal
Authors: Vargas Julian Andres Castillo
Published: April 2023

O entendimento da estrutura do átomo de carbono, possibilitou o nascimento de uma área potente da química, sendo esta a química orgânica. Mas com essa compreensão, novas perguntas surgiram. Uma destas, era a busca por entender a relação entre a estrutura atômica proposta e a estrutura de uma ampla diversidade de moléculas orgânicas na natureza. Isto levou a pensar, que a estrutura eletrônica do átomo de carbono possui particularidades, dado início ao conceito de hibridização. Neste corto documento, se apresentam noções básicas do conceito de hibridização em química orgânica e a potencial utilização deste em outras áreas do conhecimento, como o entendimento do metabolismo ruminal. Inicialmente, é feita uma breve descrição da evolução do conceito da estrutura eletrônica do átomo de carbono, para passar a adotar o conceito de hibridização do seus orbitais atômicos, com o intuito de entender as ligações formadas por este. Posteriormente, far-se-á uma breve descrição dos três tipos de hibridação do átomo de carbono (sp3, sp2, sp) bem como suas implicações na geometria das moléculas orgânicas. Finalmente, estes conceitos serão extrapolados ao entendimento do processo de biohidrogenação ruminal, mecanismo fisiológico que acontece em todos os animais ruminantes. Espera-se, com este curto documento, deixar a mensagem de que conceitos da química orgânica são claramente extrapoláveis a espaços das ciências aplicadas.
EFFECT OF MoO3 LOADING ON PRODUCT SELECTIVITY FOR CALCIUM PYROPHOSPHATE CATALYZED VAPOR PHASE LACTIC ACID DEHYDRATION

Published: April 2023

Calcium pyrophosphate and hydroxyapatite catalysts with varying C/P ratios have been previously used by our group for vapor phase dehydration of lactic acid to acrylic acid with almost 100% conversion and up to 78% acrylic acid selectivity. The activity was highly sensitive to acidity and basicity of the catalyst. Hence the catalyst with maximum activity, calcium pyrophosphate, was modified with MoO3 for modifying its acidity and to study its effect on product selectivity for lactic acid dehydration. The MoO3 modified calcium pyrophosphate with 5% MoO3 loading was used for vapor phase dehydration of lactic acid at 375°C using 50% lactic acid concentration with WHSV of 3 h-1. The activity was compared with nonmodified calcium pyrophosphate catalyst. Surprisingly, deoxygenation was predominant compared to dehydration. Acidity was observed to play a crucial role in product selectivity (i.e,. with less acidic support, calcium pyrophosphate with 5 wt% MoO3 showed more deoxygenation activity as compared to acidic support γ-Al2O3 as well as SiO2 with same MoO3 loading). Higher acidity led to formation of acetaldehyde as the only product. The results confirmed formation of propionic acid by deoxygenation of lactic acid using in situ generated hydrogen after decarboxylation of lactic acid to acetaldehyde.

Published: April 2023

The present paper reports a numerical investigation of an atmospheric pulverized coal combustor. The main goal is to study the effects of flow behavior and gas-particle interaction on combustion dynamics for various swirl numbers (SN). This will help in better understanding of the combustion properties inside a large-scale facility. The RANS and quick discretization scheme are combined during this numerical simulation. For turbulence, the realizable k-ε model is adopted. Turbulence and chemistry interaction are modeled using the finite rate/eddy dissipation model along with reduced global reaction mechanism. Four swirl numbers were investigated. The numerical results are validated with previous experimental data. Good agreement between both results is found for temperature distribution and species concentration along the center axis of the nozzle. Flow topology, temperature, particle trajectory, and species concentrations in several locations downstream the injection nozzle are presented and analyzed for the considered swirl numbers. Analysis of the flow velocity and the particle trajectory showed that the combustion behavior and flame shape were directly related to the particle trajectory inside the nozzle. The numerical results also outlined that the variation of swirl number has changed the particle trajectory and consequently the flame topology. Thus, the swirl number significantly influences the burner efficiency.

The continuous and unchecked discharge of effluents by the dyeing industry into water bodies has led to the rising importance of water treatment. This study focuses on the successful abatement of the auramine O (AM) dye in an aqueous system through a heterogeneous Fenton process using ultrasonication. Zinc oxide (ZnO) nanoparticles (NPs) were obtained by using a straightforward precipitation method and then modified with glycine (M-ZnO). The NP size sharply decreased upon modification with glycine. X-ray diffraction was used to determine the basic crystal properties, such as crystallinity. It was observed that the size of NPs sharply decreased from 24.6 nm (pure zinc oxide) to 17.3 nm upon modification of zinc oxide with glycine. A bandgap of 3.4 eV was determined for M-ZnO using a UV–visible spectrophotometer. Thermal gravimetric analysis revealed the excellent thermal stability of M-ZnO compared with that of zinc oxide. The catalytic activity for AM abatement was determined using a Fenton process at pH 6. Detoxification assays showed that pure hydrogen peroxide (H2O2) and pure zinc oxide exhibited 38 and 37% AM dye degradation, respectively. Meanwhile, M-ZnO showed 97% AM dye degradation in 240 min. A plausible mechanism is proposed for AM abatement using zinc oxide.

En el presente artículo se realiza una revisión de literatura con el propósito de analizar el estado actual de las investigaciones en torno a las políticas públicas en materia de ecoinnovación en turismo, intentando proporcionar una base de conocimiento sobre el potencial y la naturaleza de este objeto de estudio. Se desarrolla un análisis de contenido de las publicaciones incluidas en la base de datos de Web of Science, partiendo de artículos de acceso abierto bajo una ecuación de búsqueda estructurada. Se identifican 182 artículos del periodo comprendido entre 1991 y 2021, los que posteriormente son analizados y clasificados mediante los softwares Cloud of Science y Tree of Science. Los resultados muestran que el estudio de la ecoinnovación y su relación con las políticas públicas en contextos turísticos se ha llevado a cabo en países asiáticos, y que la literatura en ámbitos latinoamericanos aún se encuentra en una etapa incipiente. Igualmente, se identifican investigaciones que atienden líneas sobre las políticas que promueven el cuidado ambiental, y las políticas reguladoras que mejoran los procesos en materia ecológica, las cuales resaltan la importancia de prácticas y factores operativos. Se concluye que existe una ausencia de estudios sobre políticas reparadoras, sancionadoras y macroreguladoras para la ciencia y tecnología ambiental.

Published: April 2023

Regular visual inspection of the underwater surface of the ship’s hull to check its integrity and the degree of biofouling is necessary to ensure the safety and efficient operation of the ship. The article proposes a method for the automated solution of this problem using an autonomous uninhabited underwater vehicle (AUV) equipped with a stereo camera controlled by a tilt actuator. The movement of the AUV is carried out along equidistant lines along the ship’s hull with simultaneous video filming of the hull surface. The AUV trajectory is calculated using the visual navigation method (visual odometry). Estimated data on the localization of the AUV relative to the ship’s hull are used in the method of controlling the movement of the vehicle to ensure the stable movement of the vehicle at a given distance from the inspected surface. Direct calculation of AUV localization data is done using the proposed original algorithm, which is implemented in the form of a software tool "stereo rangefinder". The operation of the "stereo rangefinder" is based on the matching of features in images using the SURF detector, followed by the construction of a 3D point cloud. The technique for performing automatic inspection of the ship as a whole is described. Fixed stereo images are also used to build a 3D model of the surface being examined. The applied method of constructing a global spatial model of the surface is based on the union of 3D point clouds obtained for local views. The construction of a 3D point cloud for a particular view is based on a matching of 2D point features on images of a stereo pair (SURF detector / correlation calculation), followed by the use of the ray triangulation method to obtain the spatial coordinates of the points. The presence of a 3D model makes it possible to conduct a detailed visual analysis of the state of the ship’s hull. Simulation modeling of the functioning of the developed tools on virtual scenes was carried out. Quantitative and qualitative performance evaluations obtained as a result of testing showed the acceptability of the proposed method for automatic inspection of the underwater part of the ship’s hull.
The line ratio method as a possible tool for more reliable forecasting solar flashes
Authors:   Taras Shevchenko national University of Kyiv, Lozitska N. , Lozitsky V. ,   Taras Shevchenko national University of Kyiv
Published: April 2023

Already published and new observational data are given, which indicate that in the regions of solar flares there is a significant difference in the sub-telescopic structure of the magnetic field, which is absent in non-flare regions. In particular, the magnetic fields by the FeI 6301.5 and FeI 6302.5 Å lines measured in flares outside sunspot umbra have an inverse ratio of Bobs(6301.5) < Bobs(6302.5), while without flares it is mostly Bobs(6301.5) > Bobs(6302.5). The conclusion is argued that in flares this is due to the fact that at the photospheric level there is a spatially unresolved contact of flux tubes with “kilogauss” fields and the weaker background field, which have opposite magnetic polarities. Direct observational indications of particularly strong fields of opposite polarity are found in the far wings of the FeI 6173.3 Å line. New unique observational data relating to the region of the seismic source in the exceptionally powerful solar flare of October 28, 2003 of X17.2/4B class indicate that the above inverse line ratio is most significant precisely in the region of this source. A new idea for more reliable forecasting of solar flares is proposed, which boils down to the fact that new relevant information for forecasting should be obtained from monitoring observational data in the FeI 6301.5 and FeI 6302.5 Å lines.

Methods of wave analysis of time series are analyzed in detail, namely: two-spacecraft phase difference, beamforming, k-filtering, MSR (Multi-point Signal Resonator) technique. These multispacecraft methods allow to obtain a set of wave power peaks with different spatial scales at the same frequency, which is a significant advantage over the single-spacecraft approach due to existence a significant number of wave modes at the same frequency in space plasmas. The software implementation of these methods with their successful testing on artificial data is executed. The effectiveness of each method for detecting maxima in the power spectra of the magnetic field is demonstrated.
Forecasting the Patterns and Trends in Age-Specific Fertility in South Asia
Authors: Et. al. Nasriyah Arbu,
Published: April 2023

The total fertility rate (TFR) in South Asia has decreased remarkably over the past three decades. The decline is projected to continue in the coming years mostly due to the significant changes occurring in age specific fertility rate (ASFR). This study aims to investigate ASFR trends and forecast the ASFR of India, Bangladesh, and Pakistan from 2020 to 2100. The ASFRs in South Asia data separated by 7 age groups with 5-year interval from 15 to 49 years between 1990 and 2019 were downloaded from the US Census Bureau’s website. Linear regression models were used to investigate ASFR patterns from data in that period and ASFR data in the years 2010-2019 of each age group were used to forecast the ASFRs in 2020 to 2100. The forecasted results show that ASFRs in India and Bangladesh in age group 15-24 years have steep declining trends whereas ASFRs in age group 25-29 in both countries and age group 45-49 years in India have gradually decreasing ASFR trends. Age group 30-44 years in Bangladesh have slightly decreasing ASFR trends. Pakistan with previously high fertility rates are experiencing gradually declining ASFRs in all age groups. In conclusion, the change in fertility in these three countries from low stable population to high population will occur within next 40 years from 2020

This study presents the technology of developing a universal stent graft for endovascular treatment of aneurysms and aortic dissection of various localizations, without considering the vessel diameter. A self-expanding nitinol stent was used as the frame of the main trunk of the stent graft. During the study, several variants of the aortic linear graft were manufactured and tested. The optimal stiffness and diameter of the nitinol wire were selected based on the results. When creating a bifurcation module, special attention was paid to simplifying the positioning and intravascular assembly of the structure. Implantable modules have been developed for the prosthetics of the main branches of the aorta. Dacron, optimal in terms of fiber structure, was chosen as the material of the woven shell of the graft. Linear extensibility, compactness of the pile, and tensile strength during fenestration were evaluated. To determine the heparin-controlled surgical porosity, experimental samples of stent grafts were tested on a stand simulating arterial blood flow. The wall material of the developed device had a heparin-controlled surgical porosity of 50150 mL/min/cm2 at 120 mm Hg with the possibility of maintaining a controlled endolic. The graft wall created a pressure gradient of no more than 3 mm Hg, and the flow velocity indicators were quite sufficient for adequate perfusion of vital organs. After the inactivation of heparin, blood permeability became zero. The implantation technique of the developed product was implemented on a silicone aortic phantom simulating aneurysm expansion with and without dissection. The phantom contour was filled with a solution simulating the rheological properties of native blood. Pulsating blood flow was simulated using a perfusion pump. Under X-ray control, a stent graft was installed on five large biological samples (sheep). Implantation was performed in the aortic arch with prosthetics of the brachiocephalic trunk and the suprarenal aorta with prosthetics of the visceral branches. With the experiment, we hope that the result will allow us to minimally invasively help patients suffering from aneurysms of any localization.

Published: April 2023

The immediate and long-term results of the surgical treatment of hemorrhoids in two patient groups were compared. In the main group, the original technique of lateral ultrasound dissection in the cutting mode was used, whereas in the control group, hemorrhoidectomy using monopolar electrocautery was performed. The dynamics of the intensity of postoperative pain syndrome was analyzed using a specialized questionnaire. Pathomorphological changes in the removed hemorrhoids were studied as part of a comparative assessment of the damaging effects of ultrasound and electrosurgical scalpel on the tissues. To assess the extent of the influence of the surgical intervention on the function of the rectal locking apparatus, impairments in the contractile activity of the anal sphincter were analyzed by balloon manometry. The intensity of the pain syndrome and the frequency of postoperative complications were significantly lower in the main group than in the control group. The depth of coagulation necrosis and severity of necrobiotic and reactive changes when using lateral ultrasound dissection in the cutting mode were significantly less than that after electrosurgical hemorrhoidectomy. In the comparative analysis of transanal manometry data, significantly less pronounced impairment of the tonic activity of the sphincter in the postoperative period was noted in patients who underwent lateral ultrasound dissection in the cutting mode. Thus, the original technique of lateral ultrasound dissection in the cutting mode is characterized by less tissue injury, reduces the frequency of complications and intensity of postoperative pain syndrome, and contributes to faster restoration of the function of the rectal locking apparatus..

A new type of magnetising and magnetic flux leakage inspection system for the non-destructive testing of pit defects on the surface of a steel sheet
Authors: Zhang Hongjie , Xuan Hao , Gao Rongxing
Published: April 2023

A new type of magnetising and magnetic flux leakage (MFL) inspection system is designed, in which an ARM microprocessor-based measuring circuit and a novel magnetising device developed by the authors are combined to detect the magnetic field around a pit defect in a steel sheet. Based
on a series of careful detection experiments, the spatial distributions of the three-dimensional (3D) MFL components of some typical artificial defects are described and observation, comparison, feature extraction and analyses are then carried out. The results show that the 3D components of
the MFL field produced by the newly proposed magnetising device present some distinctive properties compared to those made by the traditional magnetising device. They involve rich information that exhibits close correlations to the morphology and critical parameters of the pit defects on the
near side of the steel sheet, demonstrating the feasibility, effectiveness and reliability of the newly proposed inspection system, as well as laying a good foundation for the testing, evaluation or reconstruction and inversion of the pit defect.
Preliminary Analyses on Participation and Social Stratification in Paraguay
Authors: Villalba Portillo Sara Mabel , Galeano Monti José
Published: April 2023

This article examines the level of participation of the Paraguayan population in associations and civil society organizations, according to their social stratification. The analysis is raised from the approach of the social dimension of exclusion that includes the indicator of “associationism”. The types of organizations that register the highest level of participation of the population are also identified. The methodology used was predominantly quantitative. Information on the living conditions of the Paraguayan population was collected through surveys in 4,000 homes in Asunción and the departments of Central, Alto Paraná, Itapúa, Caaguazú and San Pedro. The results showed that the highest level of participation of the population is registered in the middle socioeconomic stratum, specifically in political parties, religious associations and neighborhood commissions. In general terms, the percentage of participants in the various associations in the country does not exceed 10% of the population surveyed, including the three strata (low, medium and high).
The Foreign Policy of Contemporary Argentina. Between the Search for Autonomy and the Acceptance of Subordination
Authors: Paikin Damián
Published: April 2023

The foreign policy of Latin American countries is debated between two antagonistic positions. The logics of autonomy, on one hand, and the logic of globalism, on the other. Both views are based on a common diagnosis: the weakness of the countries of the region. However, from there they differ in their proposals. While the first presents a confrontational scenario against the powers, the second seeks an adaptive path. This “Latin American pendulum”, resulting in foreign policies oscillating according to the government, is perhaps most radical in Argentina. In this key, the present work analyzes the foreign policy of the governments of Mauricio Macri (2015–2019) and Alberto Fernández (2019–2023), seeking to understand if they put into practice the conceptual ideological foundations that they tried to impose from their actions.
Evaluasi Penerapan Metode Segmentasi Wajib Pajak: Studi Kasus Kantor Pelayanan Pajak Pratama Temanggung
Authors: Afriyanto Alan , Suwardi Eko
Published: April 2023

Penelitian dilakukan untuk menganalisis penerapan metode segmentasi dan menemukan kendala dalam penerapan metode segmentasi. Kebaruan penelitian ini adalah sudut pandang penelitian dari otoritas pajak; menggunakan teori risiko kepatuhan; dan dianalisis dari dua kategori wajib pajak (strategis dan lainnya/kewilayahan). Penelitian ini menggunakan metode kualitatif dan pendekatan yang digunakan adalah studi kasus. Kantor Pelayanan Pajak Pratama Temanggung (KPP Pratama Temanggung) dipilih sebagai studi kasus. Data dikumpulkan melalui tiga cara, yaitu wawancara mendalam, observasi, dan studi dokumentasi. Temuan dalam penelitian ini adalah sebagai berikut KPP Pratama Temanggung telah mencoba mengembangkan metode segmentasi berdasarkan SE-07/PJ/2020. Namun, mereka masih menghadapi lima tantangan utama, yaitu validitas data yang rendah; rendahnya pemahaman tentang pajak yang dimiliki sebagian besar wajib pajak; wilayah kerja memiliki medan yang berat; teknologi yang digunakan masih terbatas; dan tidak ada pemetaan pegawai. Secara umum metode segmentasi untuk wajib pajak strategis belum efektif, sedangkan metode segmentasi untuk wajib pajak lainnya sudah efektif meningkatkan penerimaan pajak. Berdasarkan temuan tersebut, implikasi dari penelitian ini adalah hasil penelitian mendukung teori risiko kepatuhan; DJP harus segera membuat regulasi terkait kerja sama dengan pemerintah daerah; dan DJP sebaiknya segera menyempurnakan aturan SE-07/PJ/2020
Estimation of suitable upper-limits for temperature, in stability comparisons between solid phases at high pressures. Study cases: carbon, oxygen, and fluorine
Authors: Montoya Javier A. , Cogollo-Olivo Beatriz H.
Published: April 2023

For most solid materials the Quasi-Harmonic Approximation (QHA) is expected to stay valid in a wide range of temperatures that get extended as we increase pressure, reaching a limit that could vastly exceed the melting temperature of the material. Hence, it becomes relevant to develop additional criteria for constraining the maximum temperature under which it still makes sense to perform stability comparisons between crystalline phases, hopefully without paying the high computational price that is required to calculating the precise melting curve for each solid phase. In this work, we report that for crystalline systems in which QHA remains accurate at high temperature, an alternative and computationally inexpensive phenomenological approximation holds well for identifying the region in the pressure-temperature (P-T) space where melting is likely to occur, meaning, the Lindemann’s criteria. By quantifying how atoms deviate from their equilibrium positions upon increasing temperature in the solid phase, we were able to constrain their P-T region of stability to conditions that are located under a line that represents an 11% average deviation of the atoms with respect to their interatomic distances, therefore, providing an approximate but reliable lower limit for the melting line which is relatively easy to calculate, and also a very useful alternative when no accurate experimental data is available and calculations do not exist or are not conclusive.
Alternative grammar teaching vs. traditional grammar teaching in Albanian tertiary education

Owing to the complex nature of the English Grammar, teachers of English language and linguistics face many challenges when teaching Grammar. Besides, it is difficult for students to master grammar structures though English teachers in Albania try hard to make grammar teaching as engaging as possible but through the traditional grammar teaching approach. The traditional approach and techniques have produced ineffective learning and inert knowledge problems. However, through alternative teaching approaches, especially the communicative one, students learn the language in all its three dimensions, form, meaning and use. This helps them to make use of grammatical structures meaningfully, accurately, and appropriately. With the view to investigate Albanian University lecturers’ perspectives in teaching English grammar in foreign languages departments in Albania, this research paper aimed to survey English Language lecturers’ most effective grammar teaching approaches and strongly suggest them teaching grammar communicatively. With the aid of a questionnaire, lecturers provided their opinions on the effectiveness of this alternative teaching approach and its impact on their students’ success. As an integral component part of language, as a mechanism that makes language move, grammar improves the quality as well as accuracy of English language writing and fluency, and the best approach to integrate it into English language teaching skills, should be applied by all English language lecturers. The questionnaire’s results show an integration of both approaches. Lecturers prefer teaching grammar communicatively to the traditional approach; however, they also use elements of the traditional one.

Authors: Jacomini Bonetti Irene
Published: April 2023

O uso de litígios como estratégia para fazer avançar mudanças sociais ensejou produção acadêmica sob diversos sentidos ao longo das últimas décadas. O debate sobre o que se convencionou chamar “cortes e transformações sociais” envolve uma vasta gama de questões que vão desde a separação de poderes e ativismo judicial até análises sobre os efeitos dos litígios e diagnósticos sobre quais condições favorecem ou mitigam a implementação de sentenças. O presente artigo retoma as principais reflexões sobre o papel dos tribunais na produção de mudanças sociais, buscando reconstruir o avanço do debate e apresentar sua configuração atual. Para tanto, são abordados os motivos que levaram a busca pela mudança aos tribunais, as questões democráticas relacionadas e duas abordagens diversas para o estudo sobre estes tipos de litígios. Por fim, apresentam-se os termos atuais do debate. A conclusão do artigo argumenta pela importância do estudo sobre cortes e transformações sociais considerando não apenas a permanência da temática na produção acadêmica, mas sobretudo a continuidade da litigância nesse sentido ao redor do mundo.
A New Method in Philosophical Counseling (IPAA)
Authors: Hagiu Adrian , Bortoș Sergiu , Tamaș Iosif
Published: April 2023

Starting from the four principles of Pólya's problem-solving method, by analogy, in this paper we propose a new method of philosophical counseling. Thus, the objectives of this study are as follows: the review of several methods of philosophical counseling; justifying the need for a new method, which we called the IPAA method; developing the four principles – the principle of identification (I), the principle of planification (P), the principle of application (A) and the principle of assumption (A). In order to achieve these, we took into account the fact that the nature of the philosophical problems faced by the clients of the philosophical counselors, whether they are existential, moral or metaphysical, can be solved on their own. Therefore, we argued that if in the first instance, clients really need the input of the philosophical counselors, as long as the latter uses the IPAA method – a problem-solving method – they can offer clients the opportunity to self-counsel. The novelty of the IPAA method consists in the fact that it offers the client, assisted and guided at the beginning by the counselor, the possibility to carry out the act of counseling outside the office, being empowered to apply the four methodical principles mentioned above. The present study is relevant in that the new IPAA method, a method focused on solving everyday problems, is a useful method for both philosophical counselors, as its application in the office helps them to train the clients in researching, understanding and assuming their own lives, as well as for the clients, because if they are assisted in the first instance by the counselor's expertise, they can independently clarify and solve their daily difficulties.
