Authors:   The Korean Society of Special Education, Yang Jihyeong , Jeon Sangshin
Published: October 2020

The purpose of this study is to examine the emotional experiences of non-disabled adult siblings while growing up among persons with developmental disabilities. We also analyzed the data according to the birth order of the siblings and suggested effective support by analyzing related support needs. For this purpose, the focus group interview was conducted once for each of the four older siblings and the four junior siblings. As a result of successive comparative analysis on these interviews, the older sibling group produced eight upper categories and 24 subcategories and the junior sibling group also produced eight upper categories and 24 subcategories. The common upper categories for the two groups were as follows. As for emotional experiences, the categories were 'How to Recognize Disabilities,' 'Experience and Emotion with Disabled Siblings,' 'Experience and Emotion with Parents,' 'Experience and Emotion with Other People,' and 'Roles as Non-disabled Siblings.' As for emotional support, the categories were ‘Necessity of Support,’ ‘When to Support,’ and ‘Support Content.’ The results of this study helped to determine areas of support for non-disabled siblings.

Published: October 2020

The emerging market economies (EMEs) – and the lower-income developing economies to an even greater extent – generally are extremely vulnerable to the COVID-19 pandemic. Many EMEs have weak public health systems, poor and financially vulnerable populations, inadequate social safety nets, limited monetary and especially fiscal policy space, and high exposure to global trade and commodity prices.
Pandemic Recession Dynamics: The Role of Monetary Policy in Shifting a U-Shaped Recession to a V-Shaped Rebound
Authors: Kiley Michael T.
Published: October 2020

COVID-19 has depressed economic activity around the world. The initial contraction may be amplified by the limited space for conventional monetary policy actions to support recovery implied by the low level of nominal interest rates recently. Model simulations assuming an initial contraction in output of 10 percent suggest several policy lessons. Adverse effects of constrained monetary policy space are large, changing a V-shaped rebound into a deep U-shaped recession absent large-scale Quantitative Easing (QE). Additionally, the medium-term scarring on economic potential can be large, and mitigation of such effects involves persistently accommodative monetary policy to support investment and long-run productive capacity. The simulations also illustrate the importance of coordinating QE and interest rate policy. Finally, the simulations, conducted within a model developed prior to the pandemic, illustrate limitations in economists’ understanding of QE and the channels through which shocks like a pandemic affect medium-term economic performance.
The Myth of Eros in Michael Field’s Sapphic Project: from a New Materialism to a Tragic Determinism
Authors: Cantillo Lucuara Mayron Estefan
Published: October 2020

El objetivo de este artículo consiste en examinar cómo Katharine Bradley y su sobrina Edith Cooper reinterpretan la figura de Safo en conexión directa con el mito de Eros en Long Ago (1889), el primer poemario que compusieron bajo el pseudónimo de Michael Field. Con este propósito en mente, seleccionamos una serie de poemas dirigidos a la deidad griega del amor, realizamos un análisis detallado de los mismos y demostramos que las Fields componen una mitografía dramática que explora la identidad paradójica del dios y, al mismo tiempo, revela toda una verdad intemporal inherente al propio mito de Eros: el amor constituye un fenómeno ambivalente que crea, inspira y eleva tanto como destruye, oprime y mata.

A utilização de tecnologias da informação em saúde para o enfrentamento da pandemia do Covid-19 no Brasil
Authors: Lobo Coelho Akeni , De Araujo Morais Indyara , Vieira da Silva Rosa Weverton
Published: October 2020

Objectives: to demonstrate how the use of health information technologies, by monitoring public access networks, contributes to the reduction of health conditions in pandemics, evaluating the use of technologies in international experiences and its potential applicability to Brazilian context. Methods: an integrative review was carried out with a survey of articles in the Scielo, Pubmed and Google Scholar databases. 21 articles and 11 different documents were selected, such as journalistic pieces, book chapters, reviews, among others. The articles were read and critically analyzed by two different researchers. A third researcher was responsible for interpreting the results. Results: the study demonstrated that there is a great worldwide trend towards the use of Information and Communication Technologies as tools to help fight pandemics, since there were several world examples that dealt with the use of technologies to control Covid-19, and that use depends on the evolution and improvement of technological tools and the legislation involved. In Brazil, there is great potential for evolution in this area, with increased data collection and use, assisting in public health strategies and actions. However, in all scenarios presented, there is a need for improvement and adjustments in the legislative scope – giving greater legal responsibility to privacy rights – and social, with the expansion of the internet infrastructure, reaching the entire population and, mainly, with the greatest reliability of the data. Conclusion: based on the understanding of the scenario of use of Information and Communication Technologies in several countries and how the responses were made in their respective territories, a comparison was made with Brazil and it was noticed that the Brazilian technological capacity is limited in a way general. Sociocultural issues in Brazil stand out, because they are, at times, barriers that exist in the Brazilian scenario, and which must be discussed, aiming at a better understanding about the use of these technologies in public policies in order to reach the entire population. With that, it was seen that it is necessary the conscious and active participation of citizens in providing correct information, for the joint and continuous improvement of data collection, and the correct use of data by the State, without harming the privacy of citizens and improving health care for the population.
Some Feasibility Problems in the Exact Solution of Сontrol Exercises
Authors: Rustamov G. A.
Published: October 2020

There is studied the mathematical foundations of the synthesis methodology in the engineering interpretation of a number of popular feedback control systems and the reasons for the impracticability of the results due to the appearance in the synthesis equations of pure differentiation operators and sources of various types of roughness violation. The global reason for the increasingly accelerated divergence of control theory from practice is associated with the impact on creative thinking such as mutation, incompatibility, randomness, fuzziness, asymmetry which underlies the evolution of synergetic systems. Both the "methodological crisis" and a number of seemingly insignificant engineering inconsistencies lead to a decrease in the planned efficiency of the developed control systems. There is a tendency to solve this practical problem through its excessive mathematization. As a result, there is nonsense — "the more mathematics, the worse", which leads to a "mathematical labyrinth", to exit from which the mathematical apparatus becomes more and more complicated until the creation of a new theory. It is shown that the use of even "correct" mathematical relations, which are the basis of the synthesis method, often leads to a violation of feasibility and rudeness. It is cited that the neglect of important poorly formalized technical indicators and the conditions of rudeness (robustness) when setting the problem does not allow us to obtain a constructive solution and is one of the main reasons for the discrepancy between theoretical results and practice. A number of popular directions of the classical theory of feedback control are considered: an inverse approach-compensation method, which forms the basis for constructing astatic, invariant, robust and other compensation systems; synthesis methods for systems with a finite settling time; assessment and control methods based on the concept of " inverse dynamics problems"; high gain limit systems. Violation of various types of feasibility and rudeness is demonstrated by specific examples tested on Matlab / Simulink. Computer research has made it possible to draw a number of positive conclusions that have important applied value.
Consecutive Compensator in Station-Keeping of a Surface Vessel
Authors: Borisov O. I. , Dahl A. R. , Pyrkin A. A. , Gromova F. B. , Skjetne R.
Published: October 2020

This paper addresses the problem of station-keeping of a surface vessel by means of the consecutive compensator approach. The horizontal motion of the vessel is described by a dynamic model. The model is set up in vessel parallel coordinates, with three degrees of freedom: longitudinal, transverse and rotational motion. It is assumed that the vessel is fully actuated, i.e. there is a sufficient number and type of actuators and a thrust allocation system to ensure full manoeuvrability. Thus, the control can be designed with the assumption of three independent inputs and three output signals. The longitudinal motion can be considered separately, but a cross-coupling exists between the transverse and rotational kinetics. There is uncertainty both in parameters and signals, due to the vessel mass, inertia, and damping, as well as the unmeasured derivatives. The proposed control ensures station-keeping when the vessel is subjected to external disturbances. The consecutive compensator, which is based on high-gain feedback, provides robustness. Stability analysis is presented considering the cross-terms as limited disturbances. This allows proof of exponential stability. Experimental results are included from the Marine Cybernetics Laboratory (MC lab) at the Centre for Autonomous Marine Operations and Systems (A MOS) at the Norwegian University of Science and Technology (Norges teknisk-naturvitenskapelige universitet, NTNU ). Two scenarios are investigated: the scaled vessel is subjected to external disturbance, and the vessel executes the " four corner test". The experiments illustrate the applicability of the method.

Göç-güvenlik ilişkisine dair yapılan çalışmalarda, Soğuk Savaş sonrası dönemde uluslararası göç olgusunun bir güvenlik tehdidi olarak algılanmaya başlamasıyla birlikte artış yaşanmıştır. Uluslararası İlişkiler Teorileri bağlamında düşünecek olursak, geliştirdiği eleştirel güvenlik perspektifiyle Kopenhag Okulu’nun özellikle göç olgusunun nasıl güvenlikleştirildiği konusunu anlama bakımından önemli katkıları olmuştur. Çalışmada bu perspektiften hareketle Suriye İç Savaşı’nın başlamasını takip eden dönemde Bulgaristan’ın göç ve güvenlik politikaları arasındaki ilişki analiz edilecektir. Bilindiği üzere savaşın başlamasını müteakiben pek çok Suriyeli Türkiye üzerinden Batı Avrupa ülkelerine göç etmeye başlamıştır. Bir geçiş ülkesi olarak Bulgaristan, daha önce hiç yaşamadığı bu yoğun göç dalgasını hızla güvenlikleştirerek bir güvenlik tehdidi olarak inşa etmiştir. Çalışmanın temel amacı, Bulgaristan’ın Suriyeli göçmenlere dönük politikalarını ve bu güvenlikleştirme (securitization) sürecini çok boyutlu bir şekilde analiz etmektir.

Analysis of roentgenologic parameters of the articular process of the scapula in children with instability of the shoulder joint
Authors: Proshchenko Yaroslav N. , Lukyanov Sergey A.
Published: October 2020

Background. The frequency of occurrence of dislocation of the shoulder joint is the highest among that for all other limb joints. Simultaneously, recurrent instability of the shoulder joint develops majorly in children and adolescents, which, in the future, lead to the development of persistent pain syndrome. Past evidence indicate that the features of the spatial positioning of the articular process of the scapula can be considered as a risk factor toward the development of instability in the shoulder joint among adult patients. However, there is no reliable data in the literature regarding the influence of tilt and rotation of the shoulder blade glenoid on the occurrence of instability in the shoulder joint among children and adolescents. Encouraged, we undertook this subject for our study.
Aim. To clarify the impact of changes in the version and inclination of the glenoid on the instability of the shoulder joint among children.
Materials and methods. We analyzed the survey data of 42 children with a habitual dislocation of the shoulder of traumatic and atraumatic origins. The average ages of the examined children were 15.57 1.75 and 15.07 1.64 years, respectively, for those with shoulder instability of traumatic and atraumatic origins, respectively.
Results. Statistical data processing revealed no significant differences in the versioning and inclination of the glenoid process between the groups with traumatic and atraumatic instabilities of the shoulder joint. Notably, the average values of versioning and inclination indicators were in the normal range.
Conclusion. Based on our results, we suggest that, in the childhood, the dynamic and static soft tissue stabilizers of the shoulder joint play the leading role in the formation of instability of the shoulder joint.
Extracting Inuit: The of the North Controversy and the White Possessive
Authors: Cornellier Bruno
Published: October 2020

This article critically explores the heated controversy surrounding screenings of Québécois filmmaker Dominic Gagnon's found-footage documentary of the North 2015, into which he inserted “found” clips of northern Inuit life he had extracted from YouTube as aesthetic capital for southern cinephile jouissance. In conversation with Aileen Moreton-Robinson's theorization of the white possessive, I propose that the vocabulary employed by many of the settler cultural institutions and critics defending the film—e.g., the democratic imperative to protect artistic freedom and allow reasoned dialogue about “difficult” texts to flourish in public spaces—is inextricable from the type of entitlements sustaining settler colonial claims to indigenous lands, and to indigeneity itself, as part of a free and boundless Lockean common. I argue that such default recourse to the democratic imperative of restorative dialogue actually fails to do what it pretends it is meant to do: via mutual understanding and recognition, to solve or resolve the systemic colonial inequalities that Inuit opponents of the film wish to make visible. This common recourse to the “bestowing” of a deliberative public space in the name of a necessary intercultural dialogue reflects the very structure of feeling of liberal colonial settlement and thus reveals a certain cinephilia's subjective and material investment in the white possessive.
Diabetes in Indian Territory: Revisiting Kelly M. West's Theory of 1940
Authors: Mihesuah Devon A.
Published: October 2020

The late Kelly M. West, also known as the “father of diabetes epidemiology,” asserted in his 1974 essay, “Diabetes in American Indians and Other Native Populations of the New World,” that diabetes was extremely rare among Oklahoma Indians prior to 1940. He used no ethnohistorical data, instead basing his conclusions on the absence of the word “diabetes” in medical records and in interviews he claimed to have conducted with Oklahoma Indians. Yet to the contrary, historical and ethnobotanical data reveals that Indians in Indian Territory (made the state of Oklahoma in 1907) began suffering from food-related illnesses, including diabetes or pre-diabetes, before the Civil War. West's theory of 1940 is important. His assertion has not been challenged; his essay has been cited at least 260 times and as recently as 2016. This paper discusses diabetes among Oklahoma Indians before 1940 and reinforces the importance of utilizing ethnohistorical data in medical studies dealing with indigenous health, as well as understanding the connection between the loss of traditional foodways and the modern health crisis.

Published: October 2020

This article details the development of an innovative, community-based intergenerational youth health messenger program in partnership with local youth which leverages intergenerational relationships within AI/AN families, training youth to deliver health messages to related adult women that encourage preventive health care, specifically breast health screenings. Youth health messengers convince women to attend to their own preventive health care by simultaneously communicating the importance of preventive screenings while utilizing the strength of their intergenerational relationships as both social capital and an inspirational motivator. Implications of the model and its approach for AI/AN women, the participating youth, and the larger community are discussed.

Published: October 2020

Postpartum haemorrhage (PPH) is a major cause of maternal morbidity and mortality, and one of the common obstetrical emergencies. Quite commonly, it occurs in patients where PPH is not expected. Management has to be swift and precise according to the steps and the response initiated by the uterine musculature during the management. In our patient, we had a localized multifocal atony of the uterus, at points where the uterine sinuses were bleeding due to atony, and medical management and uterine tamponade failed, with a raised D-dimer level. As the stepwise management failed with uterine devascularisation failing to control PPH, a decision for uterine compression suture (UCS), Cho suture was taken.

Published: October 2020

Los mini implantes dentales son tornillo que se insertan temporalmente en el maxilar de un paciente como anclaje para generar una fuerza y mover una pieza dental. Este artículo presenta el diseño de un dispositivo para la determinación del torque de inserción de mini implantes dentales autoperforantes en una probeta de hueso porcino. El mecanismo propuesto no requiere de accionamiento eléctrico. La entrada de potencia se da mediante el torque resultante del efecto del peso actuando sobre una polea a través de una cuerda. El dispositivo está compuesto portres transmisiones para la transformación de movimiento: transmisión por polea, engranajes cónicos de dientes rectos, y un mecanismo piñón-cremallera. Este último permite el avance longitudinal al tiempo que se da la rotación de la herramienta, haciendo posible el rompimiento del hueso e inserción del mini implante. A partir de la fuerza de inserción y de la velocidad recomendada para la transmisión piñón-cremallera, y teniendo en cuenta la eficiencia de cada estación de transmisión, se estableció la potencia de accionamiento del dispositivo. Para el caso de estudio se diseñó un portaherramientas adecuado para mini implante marca HUBIT Co x 1.4mm. Se consideraron tanto el diseño por fatiga como el diseño estático para el dimensionamiento de los ejes. El análisis de movimiento realizado permitió verificar que no existe interferencia entre ninguna de las piezas en contacto, permitiendo el avance del tornillo mediante la inclusión de un cuñero deslizante.

A mechanism synthesis and modeling for correction of hip dysplasia in medium and large dog breeds
Authors: Herrera-Perez Martin S. , Joya-Cadena Juan D. , Villegas Diego F
Published: October 2020

Hip dysplasia is an incurable but treatable disease that affects medium and large dog breeds. It appears as a result of genetic disorders, overweight, and the care given to the dogs. Currently, there are no specialized mechanisms that provide comfort to the life of these pets, while adapting to the canine condition and promoting the use of their hind legs until mobility is completely lost. Therefore, in the present study, a versatile device was synthesized and modeled to help to improve the life quality of dogs, taking as a reference the "German Shepherd" breed. It was designed considering the health and welfare of these animals, taking into account the mobility and safety of their limbs. This device uses a linkage mechanism to provide structural support to the dogs, while allowing for mobility within an specified range of motion. It aims to incorporate a gear and spring system that controls the weight lifted by the device, so that dogs partially use their hind legs. The static and dynamic behavior of this mechanism were mathematically modeled, finding an optimal solution.

Authors: Manshina N.G. , Vedyasova O.A.
Published: October 2020

In acute experiments on anesthetized rats, the respiratory responses to local administration of GABA (10^{-5}М) and noncompetitive GABAA antagonist penicillin (10^{-7} М) into B¨otzinger complex (BC) and pre-B¨otzinger complex (PBC) were studied. The diﬀerences in the responses of respiratory frequency, inspiratory and expiratory duration after injection of GABA into the BC and PBC were found. The eﬀects were more pronounced when GABA administered into the PBC. It is shown that the response of tidal volume, in contrast, was more frequent when both GABA and penicillin injected into the BC. The question of the role of GABA receptors of BC and PBC in the realization of the inhibitory action of GABA on the temporal and volumetric parameters of breathing pattern is discussed.
