Between Legalities and Humanities in Refugee Policy: A Comparative Analysis of Indonesia and Hungary Exit Strategy Refugee Crisis
Authors: Suyastri Cifebrima , Bahri Mohammad Thoriq 
Published: October 2024

Abstract
This study compares Indonesia's and Hungary's legal and humanitarian approaches to managing the 2015–2022 refugee crisis and proposes an exit strategy for Indonesia's refugee handling. Indonesia faces challenges due to the maximum detention duration stipulated in its Immigration Law No. 6/2011, which lacks further legal basis for prolonged detention. Employing a qualitative approach with comparative literature analysis, the study reveals Hungary's emphasis on legal solutions, leading to potential human rights violations but a decrease in asylum seekers, contrasting with Indonesia's humanitarian approach, resulting in positive impacts on refugees but a surge in asylum seekers. It concludes by recommending Indonesia to conduct comparative legal research with Hungarian asylum law to develop more effective refugee policies addressing legal and political concerns. This research enhances understanding of refugee management in Indonesia and Hungary, offering insights for nations grappling with similar crises.
Exploring the Challenges and Opportunities of Alternative Finance Products with Indigenous Peoples
Authors: Blue Levon , Xing Congcong , Pham Thu , Bodle Kerry 
Published: October 2024

ABSTRACT
Indigenous peoples often invest in cryptocurrencies and non-fungible tokens (NFTs) despite limited research in this area. We undertook this research to identify the demographics of Indigenous Australians who own cryptocurrencies and/or NFTs and to understand the challenges and opportunities faced. In this paper, we provide an overview of how alternative finance is reportedly used in Indigenous communities globally. Next, we focus on 62 Indigenous Australians who own cryptocurrencies and/or NFTs and participated in our online survey. We found Indigenous Australians who had university degrees, worked full-time, and owned a home had significantly higher levels of NFT ownership. The reported challenges were mostly related to storage, and the opportunities were connected to the potential for cryptocurrencies and/or NFTs as a long-term investment. Implications from this research include a continued need for financial planners to offer advice in this area, as schools were the last place Indigenous Australians learned about these alternative financial products.
The gig economy from the freelancer’s perspective: The risk of precarianization
Authors: Zelma Emil 
Published: October 2024

Abstract

Purpose
The article, based on an empirical study and analysis of scientific literature, aims to present definitions of the concepts of “gig economy” and “precarianization”, showing the specific nature of flexible forms of employment and financial uncertainty. Then, by conducting a survey among freelancers (giggers), it aims to understand the perspective of this form of employment in terms of financial stability. The aim of this article is to show that respondents fear the risk of precarity in connection with performing professional activities as freelancers.

Methodology
The considerations in this article are based on a literature analysis and the author’s own research (an online survey of a group of 160 freelancers).

Practical implications/Originality/Value
The empirical research conducted showed how this problem may manifest itself in the lives of individuals in the context of precarianization. Uncertainty about expected income, lack of stable employment, and limited access to social benefits are the main aspects of precarianization. People affected by this phenomenon may experience constant financial uncertainty, which negatively affects their life quality and sense of stability. The results of this analysis have important practical applications, especially for self-employed people, i.e., gig workers. They allow understanding of the specificity of job insecurity and provide information that may be useful in developing strategies to cope with this challenge.

Published: October 2024

Abstract

Background
Proper functioning of the pelvic floor muscles is an important element of the urogynecological therapy. There are different methods available to teach women pelvic floor muscles contractions (PFMC), but there is still no consensus in which situations they should be used in the clinical practice.

Objectives
The aim of the study was to assess the usefulness of pelvic floor ultra-sound performed introitally with transvaginal probe (PFS-TV) for teaching PFMC. An additional aim was to check whether the avulsion of the puborectalis muscle as well as the grade of muscle contractility have an influence on the learning process.

Material and methods
The analysis was carried out on the basis of 116 patients aged between 27 and 84 years (average age 59). Levator contraction strength was assessed during palpation, using the Modified Oxford Grading (MOS) before and after teaching PFMCs. PFS-TV was used to evaluate urethral mobility (UM) parameters and to teach PFMC (ultrasound biofeedback). Levator ani muscle (LAM) trauma was identified at tomographic ultrasound (TUI) during 4D assessment.

Results
Teaching PFMC using ultrasound biofeedback (PFS-TV) resulted in an improvement of all urethral mobility parameters, positive effect on UM was observed in women with different grades of MOS. In women without avulsion and with avulsion, there was an improvement observed in UM parameters on a comparable level.

Conclusions
PFS-TV can be useful in teaching PFMC. Avulsion and MOS grade seemed to have no influence on the learning effect of PFMC when ultrasound biofeedback was used. Evaluating UM during pelvic floor sonography using three ultrasound parameters (H, D, and vector) can yield more comprehensive information than one parameter H.
Daemones Boni et Mali: The Locus of Evil in Renaissance Hermetic Neoplatonism
Authors: Putnik Noel 
Published: October 2024

Abstract
This article deals with the ways evil was conceptualized in the works of Cornelius Agrippa, the most important German representative of the Renaissance humanist current often labelled as Hermetic Neoplatonism. In a heterodox fashion of blending various Christian and non-Christian concepts developed by Marsilio Ficino, Agrippa attempted to further Christianize some aspects of Hermetic and Neoplatonic theology, cosmology and anthropology. This entailed a new interpretation of pagan deities and demons, which Renaissance Neoplatonists in general sought to disconnect from the exclusive domain of evil. A significant aspect of Agrippa’s syncretistic attempt was his interpretation of the origin and locus of evil, which, as I argue, reveals a tense coexistence of the classical Thomist concept of privatio boni and anthropological dualism of possibly Gnostic provenance.
Promoting Reflections on Decision-Making in Socio-Scientific Issues
Authors: Dejanovikj Johanna , Höttecke Dietmar 
Published: October 2024

Abstract
Socioscientific issues (SSIs) require reflective decision-making. Findings have indicated that decision-making is more often based on heuristics than rational considerations. To improve one’s decision-making, it is essential to reflect upon decisions to increase awareness of the initially applied heuristics. Furthermore, research has indicated that decision-making depends on the decision-maker’s perspective on an SSI. Using a 2x2- experimental-design, we have investigated effects of two variables on secondary students’ ability to reflect their own decision-making. Variables were (1) instruction regarding the “method of reflection”, and (2) the “perspective adopted on an SSI”, which was either individual or collective. Data on students’ reflections were collected three times. Findings showed that students who had learned a specific method of reflection outperformed others regarding the quality of their reflections. Thus, this study provides evidence for the effectiveness of explicitly teaching and learning in terms of reflecting on one’s own decision-making in the context of an SSI.

Authors: Ribas Maria , Oliveira Henrique , Akhavan-Safar Alireza , Carbas Ricardo , Marques Eduardo , Wenig Sabine , Silva Lucas 
Published: October 2024

The aim of this paper is to study the response of a polyurethane-based adhesive when subjected to different loading conditions. To achieve this, double cantilever beam (DCB) and dogbone specimens were manufactured, and tensile strength, fracture and fatigue fracture tests were performed. The results of the tensile tests revealed a tensile strength of 14.5 MPa and an elastic modulus of 0.27 GPa for the studied polyurethane adhesive. The analysis of the fatigue tests showed that fatigue crack growth starts to stabilize after 20% of the test is done, and that the adhesive used is more suitable for static loading conditions than for cyclic loading conditions, since the value of the average , 0.2 N/mm, is much lower than the value of the average , 4 N/mm.

Due to changes in the payment system caused by technological advancements in Indonesia, Bank Indonesia developed the Indonesia Payment System Blueprint 2025. This formulation focuses on initiatives to create a robust ecosystem that will steer the growth of digital finance in Indonesia, which is the ultimate goal of Bank Indonesia's long-term policy orientation. Bank Indonesia established the National Non-Cash Movement to provide a safe, effective, and seamless payment system. The purpose of this study is to examine the model of digital wallet usage and interpret the use of digital wallets among mathematics students at FMIPA Tanjungpura University. The modeling process begins with selecting parameters and forming assumptions to produce a mathematical model in the form of differential equations, finding equilibrium points, and conducting simulations. Data were obtained from questionnaires about the use of digital wallets distributed to 137 mathematics students in 2019–2022. Interpretation of the model of digital wallet usage among students of the Mathematics Study Program FMIPA Tanjungpura University obtained a cash payment-free equilibrium point obtained as = (,,) = (20.550,0,0) and obtained that the population of students who have the potential to use digital wallets has increased and the population of students who use cash payments has also increased due to the factor of digital wallet balances that have run out and make payments in cash, resulting in a decrease in the population of students who have used digital wallets.

Современные автономные подводные аппараты имеют сложную форму корпуса с расположенными на поверхности надстройками, рулями и другими элементами. В исследовании проведен экспериментально-теоретический анализ влияния выступающих частей в виде расположенной в носовой оконечности надстройки крыловидной формы, горизонтальных и вертикальных кормовых рулей на характер движения тела в приповерхностной водной среде и его гидродинамические характеристики. Впервые экспериментально на базе опытового бассейна получены зависимости относительного вертикального перемещения тела, возникающего под воздействием подъемной силы, и определены углы дифферента модели для различных значений чисел Fr. С помощью предложенной численной модели рассчитаны поля давления, формирующиеся вокруг тела при его движении, установлен характер волнообразования на поверхности воды, получены зависимости коэффициентов подъемной|силы и гидродинамического момента. Выполнено сопоставление полученных результатов с данными для аналогичной модели тела без выступающих частей. Установлено, что при движении модели с более сложной архитектурой корпуса подъемная сила и соответственно вертикальное перемещение тела возрастали. Также наблюдался существенный рост значений гидродинамического момента и соответственно углов дифферента модели, что, очевидно, связано с ростом площади смоченной поверхности.
Modern autonomous underwater vehicles have a complex hull shape with superstructures, rudders and other elements located on the surface. The study carried out an experimental and theoretical analysis of the influence of protruding parts in the form of a wing-shaped superstructure located at the bow end, horizontal and vertical stern rudders on the nature of body movement in the near-surface water environment and its hydrodynamic characteristics. For the first time, the dependences of the relative vertical displacement of a body arising under the influence of a lifting force were obtained experimentally on the basis of an experimental tank, and the trim angles of the model were determined for various values of Fr numbers. Using the proposed numerical model, the pressure fields that form around the body during its movement are calculated, the nature of wave formation on the water surface is established, and the dependences of the coefficients of lifting force and trimming moment are obtained. The results obtained were compared with data for a similar body model, with-out protruding parts. It was found that when a model with a more complex body architecture moved, the lifting force and, accordingly, the vertical movement of the body increased. There was also a significant increase in the values of the trimming moment and, accordingly, the trim angles of the model, which is obviously associated with an increase in the area of the wetted surface.

Выявлены особенности формирования радоновой обстановки в производственных и служебных помещениях и предложена методика прогнозирования уровней радона в них. На основании уравнения радонового баланса показана возможность существенного снижения дозы внутреннего облучения работников радоном посредством рациональной организации воздухообмена в помещении. Предложен подход автоматизация к экспериментальному определению кратности воздухообмена при одновременном измерении объемной активности и эквивалентной равновесной объемной активности радона в воздухе рабочей зоны.
Are given the characteristics of the sources of radioactive radon gas, which is invariably present in the working area air. Features of the radon situation formation in working and office premises have been identified and a methodology for predicting radon levels in them has been proposed. Based on the radon balance equation, the possibility of significantly reducing the dose of indoor radon exposure due to the rational organization of air exchange in the room is shown. An approach is proposed to experimentally determine the air exchange rate through simultaneous measurement of radon concentration and equivalent equilibrium radon progeny concentration in the air of the working area.
Математическая модель определения коэффициента демпфирования для конструкционных материалов
Authors: Ко Мин Ко , Тарануха Николай Алексеевич , Сысоев Олег Евгеньевич 
Published: October 2024

В настоящее время при проектировании машин, механизмов и строительных конструкций в большинстве случаев не учитываются эффекты возникновения резонанса конструкций при совпадении собственных и вынужденных колебаний механических систем. На эти эффекты сильное влияние оказывают демпфирующие свойства конструкционных материалов. В данной статье предложена математическая модель определения демпфирующих свойств материала колеблющейся механической системы с учетом внутреннего сопротивления материала. Главной сложностью является вычленение демпфирующих свойств материала из общих демпфирующих характеристик колеблющейся системы (внешняя среда, закрепление, взаимодействие частей системы друг с другом и т.п.). Наиболее явно демпфирующие характеристики материалов проявляются при исследовании свободных колебаний балки с одной степенью свободы (с учетом внутреннего сопротивления). Предложенная математическая модель позволяет достаточно просто реализовать конкретные численные решения, также хорошо коррелирует с результатами других исследований, уточняя их результаты. Отличие предложенной в данной статье математической модели от существующих решений заключается в том, что производится корректный учет внутреннего сопротивления материала колеблющейся системы.
At present, the effects of resonance in the coincidence of natural and forced vibrations of mechanical systems are not taken into account in the design of machines, mechanisms and building structures in most cases. These effects are strongly influenced by damping properties of structural materials. In this paper we propose a mathematical model for determining the damping properties of the material of an oscillating mechanical system, taking into account the (internal resistance) damping properties of the material. The main difficulty of this problem is the separation of the damping properties of the material from the general damping characteristics of the oscillating system (external environment, fixation, interaction of parts of the system with each other, etc.). The most obvious damping characteristics of materials are shown on the example of vibrations and their damping in the study of free vibrations of a beam with one degree of freedom (taking into account internal resistance). The proposed mathematical model allows to realise specific numerical solutions quite simply, and it also correlates well with the results of other studies, clarifying their results. The difference between the mathematical model proposed in this paper and the existing solutions is that the internal resistance of the oscillating system material is correctly taken into account.
