Implementation of Tawhidi String Relations (TSR) on Household Consumption
Authors: Susanto Ari , Mariyanti Tatik
Published: January 2023

In conventional economic theory, human needs are described as unlimited, while natural resources are limited. This concept breeds greed, and this is against Islam. In this paper, we will discuss consumption in Islam. The goal is to find the concept of consumption that brings benefits to humans. The study in this article is descriptive qualitative, using the Tawhidi String Relations (TSR) approach. Through the letter process or Interaction, Integrative, and Evolutions (IIE) a new understanding is created. The IIE process creates causal relationships as part of evolution. This study found a new form of understanding of the IIE process is the concept of consumption in Islam to achieve benefit. The benefit is oriented to the material (outward) and inner (reward).
Economic Burden of HIV in a Commercially Insured Population in the United States
Authors: Chen Cindy Y. , Donga Prina , Campbell Alicia K. , Taiwo Babafemi
Published: January 2023

Background: With advances in antiretroviral therapy (ART), people with HIV infection are living longer. Pre-exposure prophylaxis (PrEP) to reduce HIV infection risk continues to be underutilized in high-risk individuals. Recent data on economic burden for patients with newly diagnosed HIV-1 or initiated with PrEP are limited.

Objectives: To assess characteristics, healthcare resource utilization (HRU), and costs among adults and adolescents either with newly diagnosed HIV-1 or initiated with PrEP.

Methods: This retrospective observational study utilized data from the IBM MarketScan® Commercial Claims and Encounters database. Adults with newly diagnosed HIV-1 or those initiated with PrEP were included (index date was the first HIV diagnosis or PrEP prescription, respectively, between January 1, 2016, and April 30, 2021). Corresponding cohorts of adolescents were considered exploratory. Descriptive analyses were conducted to assess baseline demographics and clinical characteristics, and all-cause and HIV-related HRU and costs per patient per month (PPPM) during follow-up.

Results: Data from 18 154 adults and 220 adolescents with newly diagnosed HIV and 34 123 adults and 175 adolescents initiated with PrEP were included. Approximately 70% of adolescents and 9% of adults receiving PrEP were female. Baseline depression/anxiety was present in 16.1% and 24.6% of adults and 14.5% and 45.1% of adolescents in the HIV and PrEP cohorts, respectively. Substance abuse in the HIV and PrEP cohorts, respectively, was reported in 10.1% and 7.0% of adults, and 2.7% and 17.7% of adolescents. During follow-up, among adults with newly diagnosed HIV, mean (SD) total all-cause and HIV-related PPPM costs were $2657 ($5954) and $1497 ($4463), respectively; pharmacy costs represented 47% of all-cause costs and 67% of HIV-related costs, but only 37% of patients had an HIV-related prescription. All-cause costs PPPM for adults with PrEP were $1761 ($1938), with pharmacy costs accounting for 71%.

Conclusions: Despite advances in ART, patients with newly diagnosed HIV and at-risk patients receiving PrEP continue to incur HRU costs. The chronic nature of HIV warrants further exploration of factors contributing to disease burden and opportunities to improve prevention strategies.
Pedagogika miejsca według Joanny i Jana Kulmów. Strumiany jako locus educandi
Authors: Chęcińska Urszula
Published: January 2023

Artykuł dotyczy fenomenu Strumian potraktowanych jako locus educandi. Bohaterami artykułu są poetka i pisarka – Joanna Kulmowa, oraz jej mąż – Jan Kulma, filozof i muzyk, którzy przebywali w Strumianach w latach 1961–1996. Kulmowie, zamieniając stołeczne miasto na wiejską wspólnotowość, filozoficzne doświadczanie przyrody i przestrzenną retorykę w stylu Heideggera, zamieszkali w Strumianach pedagogicznie. Zaczęli tam budować własną pedagogię strumiańską. Implikowała ona procesy edukacyjne, których celem stały się działania aktywizujące związane z poszukiwaniem twórczej ekspresji, wytworzeniem efektu artystycznego uobecnienia człowieka w świecie. Wspólnota strumiańska, jaką Kulmowie stworzyli dzięki artystycznej pedagogii strumiańskiej, nabrała cech miejskich. Stanowiła pedagogiczny wyraz emancypacyjnej troski Kulmów o prawo człowieka do indywidualizmu, wolności i twórczości, stanowiących wzór efektywnego funkcjonowania społecznego człowieka. Artykuł, w którym wykorzystano ustanowioną przez Marię Mendel terminologię związaną z pedagogiką miejsca, dedykowany jest pamięci Joanny i Jana Kulmów oraz zaprzyjaźnionej z nimi Hanny Buczyńskiej-Garewicz, autorki monografii Miejsca, strony, okolice.
Więzi z miejscem – narracyjne (re)konstruowanie tożsamości w rodzinie po-jugosłowiańskiej
Authors: Ligus Rozalia
Published: January 2023

Jest to kolejny artykuł z cyklu, w którym przedstawiono wyniki pracy analitycznej oraz interpretacyjnej z realizacji projektu „Migrujące biografie – potomkowie reemigrantów z Bośni w procesie rekonstruowania tożsamości. Pedagogiczne atrybuty przekazu międzygeneracyjnego w świetle historii życia”. Inspiracją do podjęcia badań były tożsamościowe identyfikacje mieszkańców powiatu bolesławieckiego na Dolnym Śląsku, którzy w 2018 r. mówili o sobie „My, Polacy z Jugosławii”, choć wielu z nich nigdy nie było w Jugosławii, a kraju tego od 1995 r. nie ma na mapie świata. W tekście dokonano analizy procesu konstytuowania się tożsamości na podstawie znaczenia, jakie jedna z uczestniczek badań, Barbara, nadała przestrzeni i miejscom, które dla niej stały się zarówno źródłem wiedzy na temat własnej tożsamości, jak i inspiracją do podejmowania aktywności ukierunkowanej na zmianę otaczającej ją przestrzeni publicznej.Odwołując się do opisu miejsca jako przestrzeni geograficznej, korzystałam z dwóch podejść teoretycznych. Pierwsze z nich reprezentuje socjolożka Martina Löw, która proponuje spojrzenie na przestrzeń z perspektywy ponowoczesnej. Drugie zaś opracowane jest przez dwóch psychologów społecznych i środowiskowych, tj. Leilę Scanell i Roberta Gifforda. Te dwie propozycje teoretyczne traktuję jako przykłady narzędzi interpretacyjnych, które z jednej strony ułatwiają zrozumienie możliwych sposobów odczytywania więzi człowieka z miejscem, przestrzenią materialną i symboliczną oraz uwzględniają emocjonalne, kognitywne i społeczne wyznaczniki relacji z przestrzenią, a z drugiej – pozwalają na rozpoznanie siły i znaczenia związku z przestrzenią, która staje się rdzeniem biograficznie konstytuowanej tożsamości.

Extrinsic Motivation in Farming on Earthy Stone Land in the Binongko Island Wakatobi Regency South East Sulawesi
Authors: Hidrawati Hidrawati , Rianse Usman , Iswandi R. Marsuki , Arafah Nur
Published: January 2023

Coastal areas and small island communities in the Wakatobi archipelago carry out traditional agriculture. Farming is held with a rainfed system on dry land and a dry climate. This system theoretically has non-optimal productivity. Even so, farmers still farm because extrinsic motivation influences how they manage farming land. The productivity of their farms is relatively able to meet the needs of farmers. This study aims to determine extrinsically motivations attached to the traditional agricultural systems of the Binongko community in the Wakatobi Islands. The research lasted eight months, from June 2019 to February 2020. The research data was collected with the triangulation method by observation, interviews, and literature study. The research informants were determined purposively with a chain information collection system. The data were analysed qualitatively using a phenomenological approach. Based on the results of this study, it is known that the Binongko Island community has an extrinsic motivation attached to traditional farming systems, namely, to obtain agricultural products economically, socially, and ecologically. In addition, farmers are also extrinsically motivated by the support from the government. These local wisdom techniques are implemented starting from land preparation and clearing, planting, maintenance, harvesting and post-harvesting.
Assessment of Stress Shielding around a Dental Implant for Variation of Implant Stiffness and Parafunctional Loading using Finite Element Analysis
Authors: Ishak_ Muhammad , Daud Ruslizam , Noor Siti , Noor Fazliah Mohd , Khor Chu Yee , Roslan Husniyati
Published: January 2023

Purpose

The aim of this study was to evaluate the mechanical stimuli transfer at the bone-implant interface via stress and strain energy density transfer parameters. This study also aimed to investigate the effect of different implant stiffness and parafunctional loading values on the defined mechanical stimuli transfer from the implant to the surrounding bone.

Methods

A three-dimensional finite element model of two-piece threaded dental implant with internal hexagonal connection and mandibular bone block was constructed. Response surface method through face-centred central composite design was applied to examine the influence of two independent factors variables using three levels. The analysis model fitted to a second-order polynomial equation to determine the response values.

Results

The results showed that the implant stiffness was more effective than the horizontal load value in increasing the stress and strain energy density transfers. The interaction between both factors was significant in decreasing the likelihood of bone resorption. Decreasing the implant stiffness and horizontal load value led to the increased stress transfer and unexpected decrease in the strain energy density except at the minimum level of the horizontal load. The increase in the implant stiffness and horizontal load value (up to medium level) have increased the strain energy transfer to the bone.

Conclusions

The stress and strain energy density were transferred distinctively at the bone-implant interface. The role of both implant stiffness and parafunctional loading is important and should be highlighted in the pre-operative treatment planning and design of dental implant.

Published: January 2023

In the last decade, increasing trends towards the consumption of healthier foods have forced processors of high-fat products (ice cream) to shift their formulations to higher proportions of unsaturated or “healthier” fats. Vegetable oils such as sunflower oil and VCO can be used as a substitute for milk fat, milk solids not fat (skim milk powder), sweeteners, stabilizers and emulsifiers, and mineral water in making ice cream. A study was carried out to determine the effects of the use of the ratio of sunflower oil: virgin coconut oil with palm fruit as a stabilizer in the production of ice cream on physicochemical properties (pH, proximate, overrun, viscosity, and melting rate). The use of palm fruit is based on the content of galactomannan in palm fruit. Premium ice cream with five different ratios of SO and VCO (15:0), (10:5), (7.5:7.5), (5:10), (15:0). The ice cream production involves mixing, pasteurization, homogenization, aging, and freezing. The physicochemical result shows ice cream sample with a ratio SO:VCO (5:10) obtained good physical properties, the lowest first-time drop/ shape retention, and a low melting rate compared to the others. The rheological behavior of ice cream is the non-Newtonian fluids with a pseudoplastic behavior. The apparent viscosity decreased with increasing shear rate.

Published: January 2023

Change detection is a process of identifying and quantifying the differences between images of the same scene at different times and in mango fruit crop is still a very challenging task. The major challenge of change detection in mango is discriminating between perennial fruit crops because many of these crops have similar reflectance profiles. Accurate change detection in the mango area will help the government prepare for area expansion and conservation planning. The main aim of this study was to determine the efficient change detection method for mango fruit crop among the most commonly used change detection methods. In this work, a comparative study was conducted by using Landsat 8 OLI images of two different dates i.e. 14 February, 2015 and 25 February, 2019 of the Malihabad mango region of Lucknow district. In this paper, four change detection methods namely, Vegetation Index Differencing (VID), Log Ratio (LR), Principal Component Analysis (PCA), and Image Rationg (IR) were evaluated to detect the changes in mango crop area. To extract the mango regions, Soil Adjusted Vegetation Index (SAVI) images of year 2015 and 2019 were calculated and further used to retrieve the VID, LR, PCA, and IR raster images. After that, these four raster images were thresholded to annotate the ‘Positive change’, ‘Negative change’ and ‘No change’ areas; thereafter, to obtain the final change map, masking was applied to mask out the non-mango area. Change detection accuracy was calculated using ground truth data to assess performance. After conducting the comparative analysis of all four change detection methods, it was found that the highest change detection accuracy is achieved with the VID and PCA followed by LR and IR, respectively. PCA and VID methods provided higher accuracies, followed by LR to detect changes in mango crop area. It is due to these methods' capability to enhance the information on the change.

As a metalworking fluid, vegetable-based crude jatropha oil (CJO) was used in place of petroleum-based oil. The use of petroleum-oil-based metalworking fluids poses significant environmental and health concerns. Furthermore, it has a large amount of free fatty acid (FFA), promoting physical damage. This research targets to substantially evaluate the modified jatropha nanofluids formulation as a metalworking fluid for machining processes. CJO was chemically altered using the esterification and transesterification processes to produce modified jatropha oil (MJO). To make the nanofluids, MJO was mixed with nanoparticles of Hexagonal Boron Nitride (hBN) + Tungsten Disulfide (WS2) and Hexagonal Boron Nitride (hBN) + Titanium Dioxide (TiO2) at a concentration of 0.025 wt.%. The viscosity and acid value of MJO nanofluids were assessed using ASTM standards and compared to a synthetic ester (SE). All the data indicates that the physical attributes improved throughout storage. It is possible to conclude that MJOhw (MJO + 0.025 wt.% hBN + WS2) has the ability as a long-term metalworking fluid for the machining operation. According to the experiment results, MJOhw surpasses non-additive MJO in terms of kinematic viscosity by 5.91% at 40 °C and 15.6% at 100 °C. During a one-month duration of storage time, MJOhw also improve viscosity index (319) by 18.15%. Furthermore, MJOhw has an acid value ranging from 0.34 to 0.58 mg NaOH/g. Finally, the inclusion of additives aids MJO in improving its qualities by 31.1% reduction in acid value and MJOhw demonstrates outstanding lubricating properties across all samples.

The drone becomes more recognized in the civilian sector; the drone's popularity becomes increases as time goes by. Nevertheless, despite the excitement of flying drones, several types of issues occur caused by the drone. In some circumstances, the aeroacoustics noise is a big concern, and quiet drone propellers would be more environmentally friendly to the surrounding area. Moreover, the noise from the drone can be a nuisance for the surrounding population and animals. Therefore, a solution needs to be proposed to reduce the sound level produced by the drone so that drone can be piloted in a surrounding area without breaking any noise level limit set by the government. Hence, the propeller's serrated trailing edge type is the proposed solution to this problem. The serrated trailing edge propeller can reduce several drone noise decibels based on past research. Thus, an investigation is conducted to study the thrust force between the normal propeller and the serrated propeller. The aerodynamic performance of the serrated propeller is analysed using computational fluid dynamic simulation and compared to that of the normal propeller. Ansys Fluent 2021 is used to solve the dependable RNG k-epsilon turbulence model. The thrust force, thrust coefficient, and lift coefficient operating on both propellers were all simulated. The results obtained by the transient approach for propellers have been validated by earlier experimental studies.

Published: January 2023

Universiti Tun Hussein Onn Malaysia (UTHM) elibrary is in the hot and humid tropical climate of Malaysia and has a distinctive feature of a circular courtyard and semi-outdoor spaces for practical public spaces and energy saving. This study was conducted on the ground level of the library which consists of an open terrace consisting of a cafeteria, a garden in the circular courtyard, and an air-conditioned seminar room. This study aimed to compare the thermal comfort condition of these spaces through physical and subjective measurements. Physical measurement was conducted for air temperature, relative humidity, air velocity and mean radiant temperature at the two selected sampling points on each investigated area positioned at 0.6 meters from the floor. Data were collected for three days in each area during two periods of time; 9 to 11 am and 2 to 4 pm. Subjective measurements were also collected through the distributed questionnaire to 150 respondents to determine the thermal sensation votes (TSV) of each investigated area. Calculations based on physical measurement showed the thermal comfort for both the cafeteria and garden were within 90% thermal comfort acceptability limit. PMV value for the air-conditioned seminar room was -0.45 with a PPD value of 9.03%. Both results complied with the ASHRAE 55 Standards for the acceptable condition for both naturally and air-conditioned spaces. The regression analysis showed that the comfort air temperature range based on the human response method for semi-outdoor spaces and indoor spaces were 24.8 0C to 29.0 0C and 20 0C to 23.5 0C respectively. The PMV regression analysis showed that the comfort air temperature range for indoor space was 22.4 0C to 23.5 0C. Results of the study showed that respondents perceived a higher comfort temperature range in the courtyard and cafeteria compared to indoor air-conditioned spaces, but still within the recommended range of ASHRAE 55 standard. The results of the study concluded that semi-outdoor places can potentially be designed as practical public spaces for comfortable and sustainable spaces.
Grid Adaptive Technique for Simulation of Scramjet Intake-Isolator at Hypersonic Speeds
Authors: Juluru Sandeep  , AVSS Kumara Swami Gupta
Published: January 2023

Hypersonic intake is one of the major components of Scramjet engine. It compresses the incoming hypersonic flow through a series of oblique shocks as the flow passes through intake-isolator section before entering the combustion chamber, which is essential for efficient combustion. The shocks generated inside in the intake interacts with boundary layer following shock boundary layer interaction and flow separation. The separated flow blocks the flow capture area such that engine expresses unstarting phenomenon. Understanding and mitigating such flow phenomenon is a challenging task. With respect to hypersonic speeds the experimental facilities are very limited. The only alternative to solve this problem is Computational Fluid Dynamics because of its capabilities. But validation of CFD results with analytical or experimental is the foremost prerequisite to chase computational analysis. Mostly at high speeds the precision of CFD results rest on the type of grid, number of elements and turbulence model used. So, in this paper, computational analysis of hypersonic intake is carried out through designed conditions to ensure the correct CFD process is used by varying number of elements in fluid domain by grid adaptive technique using ANSYS Fluent and satisfying Y+ parameter. The domain is analysed with various turbulence models and among them SST has predicted all the flow characteristics of scramjet intake-isolator at hypersonic speeds like separation bubble, shock reattachment, cowl shock etc similar to experimental results with the help of grid adaptive technique. So, grid adaptive technique is also proposed for simulation of scramjet intake at off-design conditions.

Published: January 2023

This research aims to determine language politeness in communicating via WhatsApp between students and lecturers. The research methodology used is descriptive qualitative with a research focus on the language style and the principle of politeness in WhatsApp using based on the ethics of sending messages. Data were collected using documentation and data analysis techniques with a normative method approach. The results of the investigation of this study indicate that the language style of students towards lecturers tends to ignore the correct language structure rules. In terms of the lexical aspect, a mixture of formal language and slang is still common. However, in communicating based on the social network, WhatsApp, some students have been able to meet the ethics of sending messages by paying attention to the principle of language politeness. Even so, there were also several messages sent by other students that contained violations of politeness to communicate based on media messages WhatsApp.

Investigaram, com base em um modelo teórico, os fatores socioeconômicos que determinam a alocação entre estudo e mercado de trabalho da juventude no Brasil. Mais especificamente, analisaram o que leva um jovem a se tornar um nem-nem, isto é, não estar empregado e nem em processo de educação ou treinamento. Para tanto, além de se considerar as características dos indivíduos já testados pela literatura, como as relacionadas aos atributos pessoais (gênero, idade e raça/cor) e atributos do lar (tamanho da família e escolaridade do chefe), procurou-se verificar o efeito do contexto social na decisão de estar na condição nem-nem. Em tal análise, considerou-se os dados do Censo Demográfico 2010, do Datasus e do Ipeadata.

Os Determinantes macroeconômicos da estrutura a termo do cupom cambial no Brasil
Authors: Fernandes Marcelo , Munhoz Ygor , Nunes Clemens
Published: January 2023

Entre os indicadores macro, consideramos a taxa de câmbio em real por dólar, o ágio do credit default swap (CDS) Brasil, o índice de preço de commodities, a taxa de cupom cambial futura, a taxa futura de juros em dólar (London Interbank Offered Rate – LIBOR), a volatilidade implícita da taxa de câmbio e a inflação implícita no Brasil. O modelo possui excelente aderência para a estrutura a termo do cupom cambial, explicando cerca de 95% de sua variação. Aumentos no ágio do CDS, na taxa de cupom cambial de três meses, na LIBOR, no índice de preço de commodities e na volatilidade implícita do câmbio estão diretamente relacionados com aumentos na curva de cupom cambial. Por sua vez, encontramos uma associação positiva da expectativa de depreciação cambial com cupons cambiais mais curtos e negativa com a parte mais longa da curva. Choques na inflação implícita têm um pequeno impacto positivo para vencimentos curtos, mas levemente negativo para vencimentos mais longos.

Published: January 2023

Uma das características mais flagrantes do desemprego é a irregularidade da sua incidência, tanto socialmente quanto espacialmente. Nos últimos anos, pesquisadores e formuladores de política têm demonstrado um crescente interesse no estudo e na interpretação de processos socioeconômicos no nível regional. Neste contexto, estudos a respeito das chances de participação no mercado de trabalho em nível regional ganham uma relevância adicional. Assim, este estudo tem por objetivo analisar como as características individuais e do município no qual os indivíduos estão inseridos influenciam a probabilidade de estarem empregados. Para tanto, é utilizado um modelo logit multinível, com dois níveis hierárquicos, um individual e um municipal. Adicionalmente a esta abordagem, aplica-se um modelo hierárquico-espacial, de modo a se contemplar o problema da autocorrelação espacial. Os principais resultados indicam que, no Brasil, têm maior probabilidade de estarem empregados os homens, brancos ou amarelos, com ensino superior completo e que possuem cônjuge/companheira. Além disso, nota-se uma forte relação entre os indicadores municipais de renda e saúde – bem como essas variáveis defasadas espacialmente – e as chances de participação no mercado de trabalho.
A Framework for Obtaining Accurate Posteriors of Strong Gravitational Lensing Parameters with Flexible Priors and Implicit Likelihoods Using Density Estimation
Authors: Legin Ronan , Hezaveh Yashar , Perreault-Levasseur Laurence , Wandelt Benjamin
Published: January 2023

We report the application of implicit likelihood inference to the prediction of the macroparameters of strong lensing systems with neural networks. This allows us to perform deep-learning analysis of lensing systems within a well-defined Bayesian statistical framework to explicitly impose desired priors on lensing variables, obtain accurate posteriors, and guarantee convergence to the optimal posterior in the limit of perfect performance. We train neural networks to perform a regression task to produce point estimates of lensing parameters. We then interpret these estimates as compressed statistics in our inference setup and model their likelihood function using mixture density networks. We compare our results with those of approximate Bayesian neural networks, discuss their significance, and point to future directions. Based on a test set of 100,000 strong lensing simulations, our amortized model produces accurate posteriors for any arbitrary confidence interval, with a maximum percentage deviation of 1.4% at the 21.8% confidence level, without the need for any added calibration procedure. In total, inferring 100,000 different posteriors takes a day on a single GPU, showing that the method scales well to the thousands of lenses expected to be discovered by upcoming sky surveys.
