Istilah "teologi" mengacu pada metode tertentu dalam mengkonseptualisasikan ajaran agama dan ajaran secara keseluruhan. Itu dikembangkan untuk tujuan memahami perilaku manusia secara umum, tetapi juga mencakup perilaku manusia pada khususnya, perilaku manusia pada khususnya, perilaku manusia pada khususnya, dan perilaku manusia pada umumnya. Jika dilihat dalam konteks Islam, bahasa filsafat cenderung lebih lamban dan rancu jika dibandingkan dengan terminologi Islam; akibatnya, setiap teori filosofis yang dibahas adalah salah satu yang berakar pada Islam. Dalam konteks teori pendidikan, tidak menutup kemungkinan siswa akan belajar tentang pendidikan atau akan belajar tentang pendidikan dari aliran-aliran mutakallimin. Kajian tersebut merupakan interaksi tunggal, yaitu proses berinteraksi dengan orang lain melalui bahasa. Ia adalah eksposisi dimana dan dengan itu manusia mengembangkan dan menciptakan keterampilan yang diperlukan untuk mengubah dan memperbaiki kondisi umat manusia dan lingkungannya, demikian pula pembentukan sikap yang membimbing-usahanya membina kembali sifat kemanusiaan dan jasmaninya. Sistem pendidikan Islam dikenal dengan At-Tarbiyahi (Pendidikan), dan kurikulumnya berbasis Ar-Riyadhah (Latihan). Latihan yang disebutkan di atas sebanding dengan latihan jasmani dan rohani. Tujuan pendidikan Islam adalah memuridkan Allah yang bersifat taqwa, dan memuridkan duniawi dan ukhrawi.

Published: July 2023

An embedded microring resonator model using PtS2 as the core layer was designed and optimized for sensing. The inner layer is made of PtS2, and SiO2 and Si3N4 are used as cladding. The overall structure is Si3N4-SiO2-PtS2-SiO2-Si3N4. Field strength distribution of longitudinal section of single straight waveguide and the longitudinal section of coupling part of straight and annular waveguides are simulated according to the coupled-mode theory. The transfer matrix method is used to analyze characteristics between the length of the U-shaped feedback waveguide and the circumference of microring and the change of attenuation factor and coupling coefficient on the output spectrum. The simulation results showed that the embedded microring resonator with PtS2 as the core presents excellent optical properties. The resonance depth is more than –50 dB, and the sensitivity can reach 1806.61 dB/RIU. When the resonance wavelength is 1550.86 nm and the self-coupling coefficient is 0.9849. The corresponding detection limit is about 1.66056 × 10–7 dB/RIU, and the quality factor is 2.8848 × 10–5 under the measurement system with a signal-to-noise ratio of 30 dB. Compared with the traditional single microring structure, the proposed microring presents a higher free spectral range and more suitable for the fabrication of high-sensitivity, low-detection limit, and large-measurement range sensors.
SPAD timing jitter modeling using Fourier series
Authors: Eyvazi Kaveh , Karami Mohammad Azim
Published: July 2023

In this paper, a simple analytical model for the Gaussian’s peak response part of the timing jitter of single photon avalanche diodes (SPADs) is proposed using Fourier series in the multiplication time calculation. The multiplication time characterizes avalanche multiplication process speed in which low multiplication time suggests a swifter response time and a higher avalanche speed. This paper presents an analytical solution which results in a more accurate multiplication time. The model is verified for SPADs implemented in 0.15 and 0.18 μm standard CMOS process, and the accuracy of the proposed analytical method in full-width at half-maximum (FWHM) calculation is improved by 25% and 5% with respect to the numerical model, respectively.
Measuring Communicative Intentions and Capabilities: Learners’ English Proficiency as a Supplement to Willingness to Communicate
Authors:   The Korea English Language Testing Association, Lee Hansol , Jin Seonghan
Published: July 2023

In this study, we attempted to measure English learners’ communicative intentions and capabilities (CIC) by adding their English proficiency to their willingness to communicate (WTC) as a predictor of the learners’ English use. In the context of communicative language teaching (CLT), learners’ WTC is considered the key to linking important learner factors such as self-perceived competence, anxiety, and motivation. Given that WTC only accounts for learners’ communicative intentions, we hypothesized that learners’ communicative capabilities (i.e., language proficiency) would be a meaningful addition to measuring overall CIC. To test this hypothesis, we collected a total of 67 samples (N = 17,811) and conducted an analysis using a metaanalytic structural equation modeling (MASEM) approach. The results indicated that the learners’ overall CIC successfully predicted their English use, with a significant path coefficient (β = .525, p = .02). Furthermore, we found that the size of the direct contributions of perceived competence and motivation became non-significantly marginal (ps > .05), indicating that adding learners’ proficiency to the WTC to measure the overall CIC can improve the overall explanatory power of the MASEM model to predict learners’ English use.

Development and Application of an Energy Management System for Electric Vehicles Integrated with Multi-input DC-DC Bidirectional Buck-Boost Converter
Authors: Babu Jarapala Ramesh , Nayak Manas Ranjan , Mangu B.
Published: July 2023

The rise in environmental pollution, demand for fossil fuels, and higher fuel economy vehicles has raised concerns about the creation of new and efficient transportation vehicles in recent days. These days, most developments in electric vehicles concentrate on making the vehicles more pleasant to ride in. Nonetheless, the emphasis now should be on energy and its most efficient use. To do this, you must give your attention to the origin of the automobile. The answer to this problem may be found in hybrid energy storage systems (HESS). This work is concerned with the design and implementation of an effective energy management system in electric vehicles (EVs) equipped with an active HESS consisting of a battery and a super capacitor via the incorporation of load sharing into this hybridization under a variety of load demand scenarios. To address the demands of high fuel efficiency vehicles, automotive firms are focusing on the development of diesel-engine operated vehicles, electric vehicles, fuel-cell vehicles, plug-in electric vehicles, and hybrid electric vehicles. A Multi-input Bidirectional Buck-Boost (MIB3) DC-DC converter is proposed in this dissertation to provide a greater conversion ratio to the input DC voltage. The multi-input converter recommended has fewer components and a simpler control method, making it more trustworthy and cost-effective. This converter also has bidirectional power flow functionality, making it suitable for charging the battery during regenerative braking in an electric or hybrid vehicle. Three different energy sources are used in the suggested topology: a photovoltaic (PV) panel, a battery, and an ultra-capacitor

Contractual and Actual Situation of the White Émigrés Who Participated in the Chinese Civil War in the 1920s
Authors:   Kursk State University, Pashin Vasiliy P.
Published: July 2023

In modern conditions, scientific interest in the tragedy of the split of Russian society in the first quarter of the 20th century has been growing. The works being published cover various aspects of the life of white émigrés, including in the Far East. It should be noted that Soviet historiography was created on the basis of Marxist-Leninist methodology. In the second half of the 1980s through the 1990s, some researchers tried, often mechanically, to present historical events in a different light. It is only in contemporary Russia that a clear picture of the historical past has begun to emerge. Based on the archival documents from the Foreign Intelligence Service of the Russian Federation, introduced into scientific circulation for the first time, this article substantiates the reasons and describes the conditions for the participation and military presence of white émigrés in the Chinese Civil War (1927-1936). The materials are diverse in origin and include reports, summaries and analytical reports of the Harbin and Beijing residencies of the Foreign Department of the Joint State Political Directorate, as well as intelligence reports of various kinds received by Soviet intelligence. Their comparative analysis demonstrated a clear objective picture of the presence of white émigrés in China. It is proved that the share of the white Guard diaspora located in China that took part in the civil war was extremely small. Attempts to formalize the participation of White Guard mercenaries in the Chinese Civil War and put it into legal framework are revealed. The documents found show contractual requirements of the white diaspora leaders for the Chinese authorities to ban the use of the Russian mercenary detachment in punitive operations against civilians outside the three provinces of China. Further, the effectiveness of the military operations of the Russian detachment in Marshal Zhang Zuolin’s army was analysed, as well as the reasons for its demoralization and disintegration. A conclusion is substantiated about the importance of helping Russian citizens who emigrated out of necessity or as a result of delusions and who did not stain themselves by an open conflict with their own people. They must not be cut off completely from their motherland.
Symbolic Resources of Local Cultures in the Experience Economy

In the post-industrial world, traditional communities are becoming active participants in market interactions, employing the mechanisms of capitalization of their local cultures’ material and symbolic components. The theoretical model of symbolic resources helps to identify both common and specific traits of the cultural institutes that determine the value of the “location” in the economic exchange, social communication and artistic processes. The concepts of creative industries demonstrate complementarity of the approaches to the analysis of cultural commodification that have developed in the economy of culture and within cultural studies. The interdisciplinary perspective reflects the way cultural industry operates at the level of actors, products of their co-production and their cooperation spaces. The experience economy theory shifts the focus from the consumption of ready products to the audiences’ involvement in the processes of personal transformation in local cultural contexts. The conversion of a customer’s situational experience to a sustainable need for cultural participation takes consequent steps. Each step adds value to the material and symbolic assets of an area. The model of the value chain of experience localization shows how the mutual influence of creation, production, consumption and dissemination of goods and services allow the viewer to co-participate in a “play” on the local “cultural stage”. The interaction of semiotic codes and material base of creative products frames the cooperation of creators, marketers and consumers in each sector of the local experience production. Preservation of traditions that represent the local communities’ way of life and their historical memory is an important strategy of creative businesses on the regional, national and global markets. The theory describing how the actors of the experience economy articulate the symbolic resources of certain territories can be used to analyse innovations within creative entrepreneurship and to evaluate the current state of traditional cultures.
A virada social e política de António Botto em Ainda não se escreveu (1959)
Authors: De Paula Neto Oscar José
Published: July 2023

Ainda não se escreveu (1959), livro póstumo de António Botto, reúne a po­esia realizada durante os seus anos de exílio no Brasil (1947-1959). Entre os variados temas que são abordados na obra, uma das principais marcas é a virada social e política empreendida pelo poeta em sua fase tardia, significativa da substancial reformulação do seu projeto poético. Nesse conjunto de poemas, o poeta apresenta uma ambivalente e contraditória maneira de refletir as questões sociopolíticas de seu contexto histórico, revelando um testemunho que mescla posicionamentos conservadores, sobretudo anticomunistas e católicos, com outros progressistas, com cer­tos ecos e procedimentos da poesia neorrealista.

A partir do diálogo com a literatura colonial portuguesa e com a literatura nacionalista angolana, este artigo analisa representações sobre a rainha Jinga em dois romances angolanos, A gloriosa família, de Pepetela (1997), e A rainha Ginga, de Agualusa (2015), com o objetivo de verificar as formas de retratar a identidade de gênero de Jinga, suas habilidades guerreiras e diplomáticas, sua maneira de governar e lidar com o tráfico de pessoas escravizadas. Como romances pós-coloniais, o corpus abarca a humaniza­ção da personagem histórica, dessacralizando-a e questionando a insíg­nia de bárbara.

Representações identitárias, história e romance: apontamentos sobre a Geração de 1870 no Brasil e em Portugal
Authors: Rezende Mota Maria Aparecida
Published: July 2023

Nas décadas finais do século XIX, um conjunto de letrados brasileiros e portugueses – a Geração de 70 – ocupou-se em explicar seus países e pro­por soluções para integrá-los à “marcha da civilização”. Entretanto, seus escritos manifestam uma tensão básica: se, de um lado, França e Inglater­ra forneciam o padrão a alcançar por ambas as sociedades, consideradas atrasadas (Brasil) ou decadentes (Portugal); de outro, poderia conduzi-las à perda do “caráter nacional”. No esforço de (re)criar suas respectivas na­ções, a Geração de 70 deixou, no traço realista do Romance e na escrita objetiva da História, autoimagens do ser português e do ser brasileiro. Ao analisar essas representações identitárias, privilegiou-se o papel central do imaginário social na construção simbólica da comunidade no interior de um discurso localizado social e historicamente.

Published: July 2023

The goal of this research is to assess the influence of financial ratios like Current Ratio, Total Asset Turnover, Debt to Equity Ratio, and Return on Equity on stock prices that are calculated using closing prices. Moreover, the data used for this study is taken from the financial statements of Heavy Construction and Civil Engineering Companies listed on the Indonesia Stock Exchange (IDX) within the time frame of 2017 to 2021.In the research project there are 23 Heavy Construction and Civil Engineering Companies involved. The selection process for the sample includes choosing 10 companies based on predetermined criteria using a purposive sampling method. Stock Price is considered as the dependent variable, while the independent variables consist of Current Ratio, Total Asset Turnover, Debt to Equity Ratio, and Return on Equity. The chosen data analysis method for this study is employing multiple linear regression. This approach encompasses conducting descriptive analysis as well as assessing classical assumptions. Moreover, it involves performing multiple linear regression analysis while using an F-test for evaluating the model fit alongside t-tests for testing hypotheses. Also, the determination coefficient is calculated in order to determine the percentage of influence exerted by the independent variables on the dependent variable.
Prediction of solar activity time series using LSTM artificial neural network
Authors:   Polar Geophysical Institute, Kozelov Boris V.
Published: July 2023

A numerical model for predicting the parameters of solar activity — the number of sunspots R and the radioflux at a wave of 10.7 cm F10.7 ahead for 27 days — has been built. The numerical model uses an artificial neural network (NN) with LSTM (Long short-term memory) layers. For both the number of sunspots and the radioflux, the model predicts the levels and limits of variation of the values for 27 days. The average absolute prediction error of the model is less than 6 %. The real-time model is implemented on the site http://aurora.pgia.ru and can be an addition to long-term forecasts of other INTERNET resources.

This paper describes a method for organizing parallel computing on graphics processors using CUDA technology, in relation to the general circulation model of the lower and middle atmosphere of the Earth. This model is being developed at the Polar Geophysical Institute and is based on the numerical integration of a complete system of equations for the dynamics of viscous atmospheric gas on a high-resolution spatial grid in a spherical layer around the Earth's surface. The model includes a block for calculating the transfer of solar and thermal radiation, which also uses parallel calculations based on CUDA technology.
Between Doctrine and Democracy: Examining Church-State Relations and Reproductive Health Policies in The Philippines, 1990-2017
Authors: Casas Kurt D.
Published: July 2023

The question remains as to why the Catholic Church, with its moral authority and political influence, was unable to effectively oppose the implementation of reproductive health policies in a predominantly Catholic Philippines. Thus, this study examined the relationship dynamics of the Church and the state in the context of reproductive health policies in the country. Using the historical method, the data were mainly gathered from the Pastoral Letters issued by the Catholic Bishops Conference of the Philippines, the Official Gazette of the Republic of the Philippines and surveys conducted by opinion polling bodies. The collected data were then analyzed using historical approach and source criticism. The study revealed that the opposition of the Catholic Church to reproductive health policies has been always based on its teachings and doctrines on the dignity of the human person, the nature of marriage and purpose of sexual intercourse. Moreover, it also showed that political support and regime survival were important factors that determined the response of the government officials to Church criticisms and opposition to reproductive health policies. The wide public support for reproductive health policies and its successful implementation despite strong opposition from the Church implied that the stand of the Catholic Church on the issue failed to adapt to sociopolitical changes and respond to the changing needs of the Filipino people.
A Comparative Study on the Stabilization of Soft Soil Using Agricultural Wastes (Baggase Ash (BA) And Rice Husk Ash (RHA)

Published: July 2023

Soft soils are expansive soils, also referred to as tropical clay. Soft soil may cause instability to foundations thereby reducing their service life, this necessitates the adoption of a suitable soil stabilization method in order to improve the engineering properties of soft soils. This research work aims at comparing the strength properties of soft soil stabilized using two different agricultural wastes- Bagasse Ash (BA) and Rice Husk Ash (RHA). The studies were conducted to determine the properties of the natural and treated soft soils, the oxide composition of BA and RHA and the evaluation of the effect of BA and RHA (0, 2, 4, 6, 8, 10 and 12 % by dry weight of the soil) on the index and strength properties of soft soil, the determination of strength characteristics (proctor compaction , unconfined compressive strength (UCS), and California bearing ratio, (CBR) under soaked and unsoaked conditions) of soft soil with BA and RHA mixtures, the optimum blend of both BA and RHA needed for the stabilization of clay soil, the comparison of BA and RHA as stabilizing agents on the performance of clay soil. From the test results, it was observed of the natural moisture content of the clay soil was to be 18.02%, indicating that the soil material is a relatively high water holding material with very low porosity and specific gravities of 2.66. The maximum dry density (MDD) of BA treated soil increased with higher BA content to an optimum BA content lying between 8-10% of dry clay soil and MDD of RHA treated soil continuously decreased with addition of RHA to the clay soil. OMC of BA and RHA treated soils continuously increase, the BA treated clay soil increase with increase in BA content with a possible percentage increment of 11.20% and RHA treated clay soil increases continuously with addition of RHA to a percentage increment of 16.2%. BA content leads to a consequent increase in CBR to an optimum value of 9%. The optimum value of RHA content was obtained as 10% with a maximum CBR value of 28.72%. BA treated clay soil increase both CBR and UCS to percentage increment change of 630% and 91.41% respectively while percentage increments of 619.8% and 85.23% were recorded for RHA treated clay soil. BA thus improved the strength properties better in comparison to RHA although in smaller optimum percentage addition.
