THE U.S. FINANCIAL QUANDARY: ZIRP’S ONLY EXIT PATH IS A CRASH
Authors: Hudson Michael
Published: July 2023

Interest-bearing debt grows exponentially, in an upsweep. The non-financial economy of production and consumption grows more slowly as income is diverted to carry the debt overhead. A crash occurs when a large part of the economy cannot pay its scheduled debt service. That point arrived for the U.S. economy in 2008, but was minimized by a bank bailout, followed by a 14-year boom as the Federal Reserve increased bank liquidity by its Zero Interest-Rate Policy (ZIRP). Flooding the capital markets with easy credit quintupled stock prices and engendered the largest bond market boom in U.S. history, but did not revive tangible capital investment, real wages or prosperity for the non-financial economy at large.
Reversing the ZIRP in 2022 caused bond prices to fall and ended the run up of stock market and real estate prices. The great 14-year debt increase faced sharply rising interest charges, and by spring 2023 a number of banks failed, but all their depositors were bailed out by the Federal Deposit Insurance Corporation (FDIC) and Federal Reserve. The open question is now whether the U.S. economy will face the financial crash that was postponed from 2009 onwards by the vast expansion of debt under ZIRP that has added to the economy’s debt burden.
 
EL DILEMA FINANCIERO DE ESTADOS UNIDOS: LA ÚNICA SALIDA A LA POLÍTICA DE TASA DE INTERÉS CERO ES UNA BANCARROTA
RESUMEN
La deuda con intereses crece de forma exponencial como una curva ascendente. La economía no financiera de la producción y el consumo crece más lentamente conforme el ingreso se desvía para solventar los gastos de la deuda. El crac financiero ocurre cuando una gran parte de la economía no puede pagar el servicio de su deuda programada. Ese momento llegó para la economía de Estados Unidos en 2008, pero fue minimizado por un rescate bancario, seguido de un auge de 14 años porque la Reserva Federal incrementó la liquidez mediante su política de tasa de interés cero (ZIRP, Zero Interest-Rate Policy). La inundación de los mercados de capital con crédito fácil quintuplicó los precios de las acciones y generó el auge del mercado de bonos más grande en la historia de Estados Unidos, pero no reanimó la inversión de capital tangible, los salarios reales ni la prosperidad de la economía no financiera en general. El abandono de la ZIRP en 2022 causó un descenso de los precios de los bonos y puso punto final al auge del mercado de valores y de los precios de los bienes raíces. El gran aumento de la deuda de esos 14 años confrontó drásticos cargos de tasas de interés crecientes y en la primavera de 2023 un número importante de bancos quebró, pero los depósitos de sus clientes fueron rescatados por la FDIC y la Reserva Federal. La pregunta abierta es si ahora la economía de Estados Unidos experimentará el crac financiero que fue pospuesto desde 2009 en adelante por la vasta expansión de deuda de la ZIRP que ha acrecentado el peso de la deuda de la economía.
BANK RUNS IN PRACTICE AND THEORY
Authors: Pérez Caldentey Esteban , Vernengo Matías
Published: July 2023

The paper shows that past bank run episodes in the United States display a common pattern. Runs are endogenous to situations of perceived insolvency concerns resulting from the adoption of risky practices driven by the profit motive within a context of lose/inadequate regulation or deregulation. Risky practices make financial institutions more vulnerable to changes in external conditions. The mainstream approaches to bank runs are based on a characterization of an economy that resembles a cooperative economy (all resources are shared equally by all participants) rather than an entrepreneur economy whose end-motive is profit making. As a result, they provide implausible stories about bank runs. Building on the stylized facts of bank runs this paper presents the main building blocks for an alternative theory.
 
LAS CORRIDAS BANCARIAS EN LA PRÁCTICA Y LA TEORÍA
RESUMEN
Este artículo muestra que los episodios pasados de corridas bancarias en Estados Unidos exhiben un patrón común de comportamiento. Las corridas son endógenas a situaciones de insolvencia percibidas como resultado de la adopción de prácticas riesgosas impulsadas por el afán de lucro en un contexto de regulación o desregulación de pérdidas/inadecuadas. Esto hace que las instituciones financieras sean más vulnerables a los cambios en las condiciones externas. Los enfoques convencionales de las corridas bancarias se basan en una caracterización de una economía que se asemeja a una economía cooperativa (todos los recursos son compartidos por igual por todos los participantes) en lugar de una economía empresarial cuyo motivo final es la obtención de beneficios. Como resultado, proporcionan historias inverosímiles sobre las corridas bancarias. Sobre la base de los hechos estilizados de las corridas bancarias, este documento presenta las principales premisas para una teoría alternativa.

Authors: Rubio Cisneros Igor Ishi
Published: July 2023

Este trabajo combina la ingeniería aplicada y los servicios ambientales para el bienestar del municipio de Guadalupe en el estado de Nuevo León. El norponiente del río y cerro de la Silla son áreas con riesgo y peligro geológico e hidrometeorológico, allí la población está vulnerable en cada evento meteorológico y recursivamente los daños ascienden a millones de pesos (mdp). Se analizaron 24 colonias en 6 cuencas hidrológicas superficiales con encharamientos y las zonas susceptibles de riesgo geológico reportados en el Atlas de Riesgos estatal. Se determinaron algunas zonas para mejorarse, regenerar y ampliar el espacio público basado en las compensaciones ambientales para infiltrar y estabilizar el agua, suelo o macizo rocoso. Para cada sitio se calcularon las compensaciónes por riesgo geológico, hidrometeorológico y otros servicios ambientales. El método de línea clave o key line en 6 cañadas y parques ofrece una solución para controlar el escurrimiento del agua, la distribución de la infraestructura y los patrones de las áreas verdes aguas abajo en las colonias. El valor estimado de los servicios ambientales es para 21 aspectos de lo urbano y lo natural. El costo estimado para las compensaciones de la estabilidad en zonas susceptibles con riesgo geológico asciende los $28.7 mdp, y $23.8 mdp para la protección a inundaciones. Valorar los espacios urbanos junto con los servicios profesionales en geología e hidrometeorología puede ser un método útil para evaluar los desastres naturales y una herramienta en la toma de las decisiones para proteger a la población.

Published: July 2023

Canceling the effects generated by inertia in the mechanisms is a complicated task with great benefits, such as reducing the Chattering effect and, in turn, energy consumption. In this article, a methodology is proposed for the cancellation of the effects produced by inertia in 1 degree of freedom mechanisms. As a solution, a control system is proposed with the application of a Time Base Generator (TBG), merged with a Proportional-Integral-Derivative (PID) controller and to limit the error, a sliding surface (SMG), to finally reach the desired position in the mechanism. The main contribution of this work is to develop the algorithm to cancel the effects produced by inertia when exist a dynamic change in the mechanism, thus obtaining a decrease in the Chattering effect presented in the rotary actuators. As a secondary contribution in this work, speed has a Gaussian campaign behavior similar to the curves drawn by the extremities of the human body, thus guaranteeing the decrease of the Chattering effect and in turn reducing the energy consumption demanded by the actuator (torque) to move the mechanism. The work has as an experimental object a 1 DOF mechanism, whose task is to lift loads vertically. In the analysis the controller reaches the desired position in a finite time, eradicates the speed fluctuations that give rise to an over acceleration when the mechanism changes from rest to a state of movement. The controller compensates the disturbances generated by the loads applied to it. The results show a functional and safe controller, capable of bringing the mechanism to a desired position in a defined time, eliminating the effects of inertia (Slinky effect).

Abstract: Due to the exponential increase in traffic nowadays, the incidence of accidents also increases proportionally. With the rapid increase in accidents, the ability to predict and predict the best path to an accident is very important not only for the transport department to make scientific decisions, but also for individuals to know less paths to accidents to travel the safest way. According to the current scenarios, it would be good to analyze the correct path with less accidents. In this, we studied the interrelationship between accidents, road conditions, weather conditions and predicted a safe and less frequent accident occurrence path among all the paths that can be taken from the source to the destination. We built using machine learning algorithms like Support Vector Machines and Logistic Regression. The main topic is to design the safest route of all the routes based on the accident rate. Conditions such as weather conditions, road conditions, lighting conditions, vehicle type, etc. By inputting these conditions into a machine learning model for a specific location, one can predict the frequency of accidents that will occur at a specific location, whether the location is safe. Based on the safety of individual locations, user can concludes the safety of the path

Published: July 2023

Objectives The present study conducted meta-analysis with the goal of systematically arranging the relation between variables related to non-face-to-face class satisfaction.
Methods To this end, the study collected data in the form of dissertations and academic papers published in Korea up to 2022. The final selection of papers numbered 215, including 52 master’s theses, 11 doctoral dissertations, and 152 academic papers. The coding method for the data followed the meta-analysis methods and coding procedures by Lipsy and Wilson(2001) as well as Cooper(2010). The effect size was calculated by converting the correlated data into Fisher’s Z transformation, which was then converted back to a correlation coefficient for interpretability.
Results The analysis shows that the overall effect size of class satisfaction variables was high at .582, with effect sizes higher in the order of content, teacher, support model and system, and learner. In terms of effect size depending on moderator variable, the study found differences depending on year of issue, research subject, and non-face-to-face class type.
Conclusions This study specifically confirmed the relationship between variables related to non-face-to-face class satisfaction by organizing research related to non-face-to-face class satisfaction through meta-analysis. In order to increase the satisfaction of learners in the educational scene, effective non-face-to-face class methods or strategies should be sought.

Objectives This study aims to qualitatively investigate the life and educational experiences of Korean language teachers and explore in-depth the topics and implications they show in common.
Methods It is one of the qualitative research methods and the most suitable narrative method was used to explore the meaning inherent in human experience. In-depth interviews were conducted with five Korean language teachers with at least 10 years of experience using a semi-structured questionnaire to collect data. The specific data analysis was conducted by following the data analysis steps of narrative research proposed by Creswell(2013).
Results As a result of data analysis, the main topics that appeared in educational experiences of Korean language teachers were ‘the start of the career as a Korean language teacher by chance’, ‘students are the biggest reward as a teacher’, ‘the ambiguous status of a Korean language teacher’, ‘burden about work other than education’, and ‘emotional stability gained from fellow teachers’.
Conclusions First, the participants highly rated the value of self-realization in occupational choice. Second, learners were the ones that give the greatest reward and motivation to the participants as teachers. Third, they were pressured by the burden of work other than education, as well as concerns about their status as a Korean language teacher.

The Problematicization of educational welfare policy: Focusing on WPR (What's the Problem Represented to be?)
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Jung Min
Published: July 2023

Objectives This study examines the important educational essence and values that have been missed in the process of educational welfare developing into a policy. Through this, it was intended to derive implications for the development of educational welfare policies in the future.
Methods In this study, Bacchi's WPR was used as an analysis framework. Therefore, educational welfare policy was regarded as a discourse, and the way “problems” and solutions were composed in educational welfare policy was divided into “change in the historical origin of problem and method of reproducing problem,” “phenomenon caused by problem,” and reinterpretation of reproduced problem.”
Results In this study, it could be explained that the educational welfare policy, which has been reduced to a political means through the discourse of welfare populism, has been transformed into a “business” while excluding “students.” In addition, in the historical process of becoming a problem with educational welfare, school members also recognized educational welfare as an area of social welfare, not education. This has led to a focus on who will be in charge of the “who” business.
Conclusions Based on the results derived from this study, it was suggested that educational consideration and the necessity of enacting related laws required in the process of converting educational welfare to ‘integrated support tailored to students’.

Published: July 2023

Objectives The purpose of this study is to establish the digital competence components of Korean language teachers as a basic study to improve the digital competence of Korean language teachers in response to changes in the digital based educational environment.
Methods To achieve this research purpose, a draft of the digital competence components of Korean language teachers was established by analyzing domestic and foreign literature related to digital competence, and a second Delphi Method was conducted on 15 experts in the field of Korean language education. In the first Delphi Method, the average, standard deviation, content validity, opinion collection, consensus, and stability of each item were evaluated on a Likert 5-point scale, and the upper and detailed competence elements were rearranged and modified based on the subjective opinions of experts. In the second Delphi Method, a structured survey using the Likert 5-point scale was constructed in the same way as in the first Delphi Method, and the final digital competence components were derived after verifying the systematic, relevance, and appropriateness of digital competence elements based on expert opinions.
Results The digital competence components of Korean language teachers were finally derived, consisting of 7 upper competencies and 25 detailed competencies under 2 categories. The upper competencies in the category of basic competencies of Korean language teachers are digital device utilization, digital communication, digital citizenship, and digital safety and security. The upper competencies corresponding to the teaching and learning competencies of Korean language teachers consisted of using digital Korean language education contents, digital Korean language teaching and learning, and digital Korean language evaluation competencies.
Conclusions This study's establishment of digital competence components of Korean language teachers has academic implications for developing programs, curricula, and evaluation tools to enhance their digital competence in the future. Moreover, it provides practical implications to bridge the gap in the use of digital competencies between Korean language teacher groups in the field of Korean language education.

A Study on the Meaning of Material Imagination in Early Childhood Music Education: Focusing on Bachelard’s Theory
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Baek Jeehea
Published: July 2023

Objectives The purpose of this study is to review Bachelard's material imagination, analyze how material imagination is expressed in musical encounters of young children, and examine the meaning of material imagination in early childhood music education.
Methods After examining the historical flow of the concept and value of imagination and the distinctive characteristics of Bachelard's theory of imagination through literature research, examples were extracted from previous studies on the researcher's invented notations. How material imagination is expressed was analyzed in their invented notations.
Results Bachelard's theory of imagination overcomes the limitations of opticocentrism, and establishes the dynamic status of imagination by reorganizing the concept of motion of matter of objects. In material imagination, the essence in the depths of the object moves and approaches the subject, and the subject also recognizes the movement of the object with feelings of joy and wonder. The motility of matter possessed by the object gives the object initiative and gives it a status equal to that of the subject. In addition, the ontological qualification of the object is given due to continuous creation, which has the significance of enabling the subject to become an object.
Conclusions In the children's invented notations, the children sensed the motility of the musical characteristics of the song and created a new mental image by intertwining their experiences and environments. It can be seen that this is a creation that leads to ‘children - song of ‘everyone jump’ - invented notation - becoming’ through the manifestation of the material imagination of young children.

Methods In this qualitative study, nine early childhood teachers participated in a course of the graduate school during 15 weeks, and at this time they submitted 10 journals and participated in the group discussion, group interviews.
Results Two major themes along with multiple sub-themes were identifies including: First, the teacher's emotional journal writing experience changed from ‘unfamiliarity, difficult start’ to write down with focusing on the teacher's emotions in early childhood education to ‘objectively facing one's emotions,’ ‘discovering positive emotions, savoring them’, ‘viewing the classroom space as a living world’, and ‘considering teacher emotion in detail’. Second, the meaning of the experience of writing emotional journals to teachers can be summarized as ‘the journey to get to know me’, ‘time to empathize and comfort’, ‘the process of transferring the virtuous cycle’, and ‘time of growth’.
Conclusions In conclusion, It is expected that it will be possible to find ways to support teachers' healthy emotional experiences in the early childhood education field while awakening the importance of teacher emotions in the early childhood teacher education program and presenting directions in terms of applying the value and meaning of teachers' emotional journal writing.

Quantum-Classical Hybrid Systems and their Quasifree Transformations
Authors: Dammeier Lars , Werner Reinhard F.
Published: July 2023

We study continuous variable systems, in which quantum and classical degrees of freedom are combined and treated on the same footing. Thus all systems, including the inputs or outputs to a channel, may be quantum-classical hybrids. This allows a unified treatment of a large variety of quantum operations involving measurements or dependence on classical parameters. The basic variables are given by canonical operators with scalar commutators. Some variables may commute with all others and hence generate a classical subsystem. We systematically study the class of "quasifree" operations, which are characterized equivalently either by an intertwining condition for phase-space translations or by the requirement that, in the Heisenberg picture, Weyl operators are mapped to multiples of Weyl operators. This includes the well-known Gaussian operations, evolutions with quadratic Hamiltonians, and "linear Bosonic channels", but allows for much more general kinds of noise. For example, all states are quasifree. We sketch the analysis of quasifree preparation, measurement, repeated observation, cloning, teleportation, dense coding, the setup for the classical limit, and some aspects of irreversible dynamics, together with the precise salient tradeoffs of uncertainty, error, and disturbance. Although the spaces of observables and states are infinite dimensional for every non-trivial system that we consider, we treat the technicalities related to this in a uniform and conclusive way, providing a calculus that is both easy to use and fully rigorous.

Authors: Mirmukhamedov M. M. , Jobirov U. R. , Ganiev I. N. , Obidov Z. R.
Published: July 2023

The article contains the results of potentiodynamic and thermogravimetric research of anode behavior and oxidation of Zn22Al alloy, doped with scandium, in various media. The anode, kinetic and energy characteristics of alloys in isothermal conditions have been established. Doping of the Zn22Al alloy with scandium in an amount of 0.1 to 1.0 wt. % contributes to the increase of its anodic resistance to oxidation. The rate of oxidation and corrosion of alloys doped (0.01–0.1%) with scandium is 1.5–3 times lower than that of the Zn22Al alloy. Alloy oxidation products consist of a mixture of protective films ZnO, Sc2O3, ZnAl2O4 and Al2O3·Sc2O3.

Authors: Sarkisov S. E. , Yusim V. A.
Published: July 2023

The paper considers phenomena of formation of color centers due to intrinsic and impurity defects in fluorite crystals activated by rare-earth ions Pr3+, Nd3+, Yb3+ under γ- and UV-radiation. Using CaF2 activated with Yb3+ and Pr3+ ions as an example, the work shows the effect of the photodynamic process on the photochemical resistance to formation of color centers of a Yb-containing crystal. It also demonstrates the effect of heating on the restoration of the original color of a Pr-containing crystal after γ-radiation as a result of change in the electronic state of praseodymium ions. The features of the formation of ions in the R2+ state in CaF2:R3+ (R3+ = Pr, Nd, Yb) crystals after γ-irradiation are investigated and explained, and quantitative estimates of the R3+→R2+ conversion processes are given.

Experimentally, when testing the developed intermetallic alloy as nozzle blades of the 1st stage of a high-pressure turbine, it was confirmed that the alloy is thermally stable at temperatures up to 1200°C.
Effects of substitution of Mg for Zn IN the composition of layered double aluminum hydroxides on their physico-chemical properties
Authors: Mayorov D. V. , Kopkova E. K.
Published: July 2023

Samples of Mg–Zn–Al layered double hydroxide (LDH) have been synthesized by solid-phase interaction of Mg, Zn, and Al crystalline hydrates with (NH4)2CO3, and then studied by chemical, X-ray phase analysis, as well as by Brunauer–Emmett–Teller (BET) and Barrett–Joyner–Halenda (BJH) methods. The paper presents results of studies of structural and surface properties (specific surface area and volume of pores, distribution of pores by their diameter). It was found that an increase in the degree of substitution of Mg by Zn leads to an increase in the specific surface area and the specific volume of samples. At the same time, the distribution of mesopores has a polymodal character with a predominance of pores having dpor = 3–4 and 25–50 nm. It was found that the substitution of Mg for Zn in the composition of layered double hydroxides leads not only to an increase in the specific capacity of the monomolecular layer of LDH, but also to a stronger interaction of adsorbate (nitrogen) with their surface.

Menulis merupakan salah satu keterampilan yang penting untuk dikuasai oleh para peserta didik di samping membaca, menyimak, dan berbicara. Menulis tidak hanya sekadar mentranskripsikan ujaran, tetapi lebih jauh dari itu menulis adalah proses menuangkan pikiran berupa ide dan gagasan. Namum, bagi banyak peserta didik menulis masih menjadi keterampilan yang sulit untuk dikuasai terutama menulis karya sastra seperti puisi dan cerpen. Masalah yang seringkali muncul dalam kepenulisan adalah ide tentang apa yang ditulis dan kosa kata baku apa saja yang mesti digunakan. Hal inilah yang terjadi pada peserta didik SMP 5 Kota Jambi. Oleh karena itu perlu adanya penggunaan media yang representatif dalam keterampilan berupa flashcards elektronik. Pembelajaran memadukan metode ceramah untuk menjelaskan kata baku dan metode latihan sebagai bentuk praktik penulisan kata baku. Melalui penggunaan media flashcards elektronik dapat momotivasi para peserta didik menulis dalam kaidah yang tepat dan menumbuhkan rasa cinta kepada bahasa Indonesia
