Assessing the relationship between neural health measures and speech performance with simultaneous electric stimulation in cochlear implant listeners
Authors: Langner Florian , Arenberg Julie G. , Büchner Andreas , Nogueira Waldo 
Published: December 2021

Objectives
The relationship between electrode-nerve interface (ENI) estimates and inter-subject differences in speech performance with sequential and simultaneous channel stimulation in adult cochlear implant listeners were explored. We investigated the hypothesis that individuals with good ENIs would perform better with simultaneous compared to sequential channel stimulation speech processing strategies than those estimated to have poor ENIs.

Methods
Fourteen postlingually deaf implanted cochlear implant users participated in the study. Speech understanding was assessed with a sentence test at signal-to-noise ratios that resulted in 50% performance for each user with the baseline strategy F120 Sequential. Two simultaneous stimulation strategies with either two (Paired) or three sets of virtual channels (Triplet) were tested at the same signal-to-noise ratio. ENI measures were estimated through: (I) voltage spread with electrical field imaging, (II) behavioral detection thresholds with focused stimulation, and (III) slope (IPG slope effect) and 50%-point differences (dB offset effect) of amplitude growth functions from electrically evoked compound action potentials with two interphase gaps.

Results
A significant effect of strategy on speech understanding performance was found, with Triplets showing a trend towards worse speech understanding performance than sequential stimulation. Focused thresholds correlated positively with the difference required to reach most comfortable level (MCL) between Sequential and Triplet strategies, an indirect measure of channel interaction. A significant offset effect (difference in dB between 50%-point for higher eCAP growth function slopes with two IPGs) was observed. No significant correlation was observed between the slopes for the two IPGs tested. None of the measures used in this study correlated with the differences in speech understanding scores between strategies.

Conclusions
The ENI measure based on behavioral focused thresholds could explain some of the difference in MCLs, but none of the ENI measures could explain the decrease in speech understanding with increasing pairs of simultaneously stimulated electrodes in processing strategies.
Performance of a solution of the direct geodetic problem by Taylor series of Cartesian coordinates
Authors: Marx C. 
Published: December 2021

Abstract
The direct geodetic problem is regarded on the biaxial and triaxial ellipsoid. A known solution method suitable for low eccentricities, which uses differential equations in Cartesian coordinates and Taylor series expansions of these coordinates, is advanced in view of its practical application. According to previous works, this approach has the advantages that no singularities occur in the determination of the coordinates, its mathematical formulation is simple and it is not computationally intensive. The formulas of the solution method are simplified in the present contribution. A test of this method using an extensive test data set on a biaxial earth ellipsoid shows its accuracy and practicability for distances of any length. Based on the convergence behavior of the series of the test data set, a truncation criterion for the series expansions is compiled taking into account accuracy requirements of the coordinates. Furthermore, a procedure is shown which controls the truncation of the series expansions by accuracy requirements of the direction to be determined in the direct problem. The conducted tests demonstrate the correct functioning of the methods for the series truncation. However, the considered solution method turns out to be significantly slower than another current method for biaxial ellipsoids, which makes it more relevant for triaxial ellipsoids.
Coloring of Bi4Ge3O12 – Mn crystals induced by electric field
Authors: Bochkova T. M. 
Published: December 2021

The effect of the direct electric field on the optical transmittance of Bi4Ge3O12 single crystals doped with Mn is studied in the mode of using asymmetric contacts when only one electrode (Ag or In-Ga) is injected. It is found that changes in the optical transmittance spectra under the action of unipolar injection of electrons and holes are different. They also differ from the case of using symmetrical electrodes (double injection mode). The optimal temperature and field conditions for electrochromic coloring are determined from the correspondence between the manifestations of the electrochromic effect in Bi4Ge3O12 ─ Mn crystals and the current-voltage characteristics. It is shown that the maximum effect is achieved by injecting holes into a Bi4Ge3O12 ─ Mn sample annealed in a reducing atmosphere.

Összefoglaló. A Bouveret-szindróma egy bilioenteralis fistulán
keresztül a vékonybélbe – az esetek 85%-ában a duodenumba – jutó nagy epekő
okozta bélelzáródást jelenti. Leggyakrabban idős nők körében fordul elő. Jelen
közleményünk célja e kórkép tüneteinek, diagnosztikájának és terápiás
lehetőségeinek ismertetése egy esetbemutatás kapcsán. A 79 éves nőbeteg
felvételi hasi panaszainak hátterében típusos gyomorkimenet-obstrukciós
szindrómát okozó, a duodenumban beékelődött epekő, Bouveret-szindróma
igazolódott. A diagnózist az elvégzett natív hasi röntgen és hasi
ultrahangvizsgálatok már felvetették, de megerősítésére további képalkotó
vizsgálatot (hasi CT) és endoszkópos beavatkozást végeztünk. Ezt követően
sebészeti beavatkozás történt, melynek során a cholecystoduodenalis fistula
zárása és az epekő eltávolítása után a beteg gyógyultan távozott.
Közleményünkben a diagnózisfelállítás idejének fontosságáról, illetve a terápiás
lehetőségekről számolunk be, valamint szeretnénk felhívni a figyelmet az epekő
okozta gyomorürülési zavar ezen ritka formájára. Orv Hetil. 2021; 162(49):

Summary. Bouveret syndrome is a rare form of bowel obstruction
resulting to the small intestine – in 85% of the cases to the duodenum – caused
by a gallstone from a bilioenteral fistula. It occurs most commonly in elderly
women. The aim of the present study is to describe the symptoms, diagnostic and
therapeutic options of Bouveret syndrome due to our case report. The background
of epigastric pain of the 79-year-old woman was the typical gastric outlet
obstruction syndrome caused by Bouveret syndrome with an impacted gallstone into
the duodenum. This diagnosis was suggested by abdominal X-ray and abdominal
ultrasound; however, it was confirmed with abdominal computer tomography and
upper gastrointestinal endoscopy. This was followed by surgical intervention to
close the cholecystoduodenal fistula and remove the gallstone, finally the cured
patient was discharged. In our study, we summarize the importance of timely
diagnosis and therapeutic options, respectively, furthermore, draw attention to
this rare form of gallstone-caused gastric outlet obstruction syndrome. Orv

Published: December 2021

Background and Study Aim. The objective of this research was to determine the social representations of the game in physical education teachers belonging to the Chilean educational system, searching for the sense and meaning given by the educators to the game aspect.
Material and Methods. The study sample consisted of 14 physical education teachers, who were chosen by the convenience sampling method. Semi-structured interviews were used to collect data from the participants, maintaining gender equity. The analysis of the data obtained was by means of content analysis and the NVivo 11 program was used to process the data.
Results. Our research indicates that of the categories analyzed, the highest was the role of the game (22.29%), demonstrating the relevance given by teachers to the game in the development of meaningful learning. On the contrary, the category characteristics of the game (17.42%), describe how teachers visualize the contributions of play at the educational level, in this sense, the role of the game goes beyond motor contributions, but also provides tools for social and cognitive development.
Conclusions. For the teachers, the game promotes autonomous and proactive actions of the students, which will be beneficial to understand that playfulness in education implies not to put in contradiction the rational and emotional faculties. This comprehensive view is called full attitude, and it is a relevant step toward the understanding of the game from a complex perspective. In this area, it is evident that, in the social representations of the participating teachers, the game constitutes a natural environment in which children develop, where the physical education teacher should create an environment that facilitates the game, facilitating the expression of autonomy, freedom, creativity, and playfulness.

Published: December 2021

Background and Study Aim. The curriculum of physical education in high schools is based on learning motor skills, as well as their development in sports sections, where the 100-meter sprint dominates. The aim of the study was to determine the influence of motor skills on the 100 m running results.
Material and Methods. The research was conducted on a sample of 80 high school students in Novi Pazar and Kraljevo, aged 16 and 17 years (± 6 months). 12 variables were used to assess motor skills, three variables each: explosive power, segmental speed, repetitive power, and flexibility (standing long jump), triple jump, five jumps. For estimating segmental speed: foot tapping, hand tapping, foot tapping on the wall. For the assessment of repetitive power: lifting the torso on the Swedish bench, mixed pull-ups, squats. To assess flexibility: deep bench press, twine, stick twist.
Results. Results were obtained to confirm that there is a positive influence of motor skills on the 100 m sprint results at the level of (p=.000). The results in the 100 m sprints are statistically significantly dependent on the motor skills that manifest segmental speed and explosive power. Variables (standing long jump, foot tapping on the wall and foot tapping) have a statistically significant effect on the criterion variable of the 100 m sprint.
Conclusions. Recommendation to future researchers would be to conduct a study over a longer period of time with the aim of examining the biomechanical factors that determine the success in sprint, is the production of force in the phase of sprint acceleration and sprint deceleration.

Aim. Comparative analysis of insufficiency rate of bronchial stump sutures in pneumonectomy for lung cancer, depending on suturing techniques.
Methods. A patented technique for bronchial stump suturing has been introduced into the practice of the GOBUZ clinic Novgorod Regional Clinical Hospital based on the Department of thoracic surgery since 2015 for pneumonectomy for lung cancer. Before the introduction of the developed technique, various generally accepted methods of bronchial stump forming were used (mechanical suture, manual suture, their combination, bronchial stump coverage with mediastinal pleura, pericardial flap). A retrospective analysis of 173 case histories and operational protocols of patients with lung cancer who underwent pneumonectomy was carried out for the failure of bronchial stump sutures when using conventional suturing techniques between 2010 and 2014 (the first group of patients). We also performed a retrospective and prospective analysis of 204 case histories and operational protocols of patients in a similar clinical group when using a patented suturing technique between 2015 and 2020 (the second group of patients). Statistical analysis was carried out by using Statistica 10.0 software (StatSoft, Inc. 2011). The qualitative and quantitative indicators were analyzed by using the Pearsons 2-test with Yatess correction.
Results. A retrospective analysis shows that the failure rate in the use of generally accepted bronchial stump suturing techniques for 20102014 was 10.4%. After the implementation of the method of preventive esophagobronchomyoplasty, complications as bronchial stump suture failure were not detected in any case between 2015 and 2020.
Conclusion. The study shows high efficiency, a decrease in the incidence of complications as the failure of bronchial stump sutures in the use of the developed method of preventive esophagomyobronchoplasty in pneumonectomy for lung cancer.

Background. Assessment of the physical development of children in individual regions of the Russian Federation does not lose its relevance and requires constant updating, in this regard, it is important to study it in children adapting to the climatic and geographical conditions of the North, as well as the effect of undifferentiated connective tissue dysplasia on it.
Aim. Aim of the study is to study the gender and age characteristics of the proportionality of physical development in children with undifferentiated connective tissue dysplasia living in the Khanty-Mansiysk Autonomous Okrug Yugra.
Materials and methods. The analysis of physical development of 528 children of the second childhood and adolescence, living in the Khanty-Mansi Autonomous Okrug Yugra, was carried out. The study group consisted of 342 children (248 boys and 94 girls) with a diagnostically significant number of undifferentiated connective tissue dysplasia symptoms (from 6 to 18 stigmas). The comparison group included 186 children (111 boys and 75 girls) who did not score a significant threshold of phene signs (from 0 to 5 stigmas). Physical development was assessed according to the Quetelet II weight-height index, chest-weight indices: Pignet, Vervek, and Brugsch, as well as proportionality indices: sternum, shoulder width, pelvic width, torso shape, arm and leg length indices, cranial and facial indices, interorbital-circular index.
Results. Children without undifferentiated connective tissue dysplasia during the second childhood have a tendency to malnutrition, and are characterized by a weak physique with a tendency to narrow chest. In adolescence, the tendency towards weakness of the physique persists, while height-weight ratios deviate towards normotrophy. Children with undifferentiated connective tissue dysplasia during the second childhood and adolescence have a rectangular or trapezoidal body with an average length, as well as long upper and lower limbs relative to the length of the body.
Conclusion. The impact of the socio-ecological factors of the North neutralizes the differences in the rates of physical development in healthy children and persons with disorders caused by congenital disorders of organogenesis of the undifferentiated connective tissue dysplasia type.

Las líneas eléctricas recorren todo tipo de terrenos, incluso algunos no accesibles por tierra, por lo que este mantenimiento se lleva a cabo usando helicópteros y vehículos todo terreno, sin dejar de mencionar un peligro inherente para las personas que en tierra o escalando la infraestructura requieren muchas veces tener riesgosos movimientos que realizar en campo y en la misma infraestructura, lo que lo hace costoso, lento e ineficiente considerando que las líneas eléctricas se tienden por miles de kilómetros. El mantenimiento en líneas eléctricas de transmisión es un trabajo necesario para brindar un servicio de calidad, actualmente presenta ciertas limitaciones ya que es un trabajo riesgoso. Utilizando cámaras termográficas, lentes de zoom óptico, aeronaves no tripuladas podemos obtener la información necesaria sin necesidad de cortar la electricidad.

Published: December 2021

Introduction: Inadequate nutritional status in a person with HIV-AIDS (PLWHA) has a high risk of declining health in general. If a person is infected with HIV but has a good nutritional status, his immune system will be better than someone who is infected with HIV but has poor nutritional status. With good nutritional status, it can prevent HIV disease from entering the AIDS stage. Malnutrition that occurs in a person with HIV/AIDS can accelerate the progression of HIV disease and hinder treatment, thereby worsening the patient's condition. The use of Antiretroviral (ARV) has an effect that can worsen a person's condition if it is not accompanied by good nutritional intake.Methods: The method used in this study is a literature review with predetermined inclusion and exclusion criteria. Sample: The total number of samples obtained from the results of the literature review is 128 respondents. The instrument used in evaluating the research is using an instrument from The Joanna Briggs Institute (JBI). Results: Protein-energy enriched macronutrient supplementation along with ARV initiation was effective in improving physiological nutritional status and immune response in PLWHA.Conclusion: This can prevent people living with HIV from experiencing malnutrition and wasting, can restore the ideal body weight, increase and maintain the body's ability to fight various opportunistic infections, increase the effect of drugs, and can improve and improve the quality of life of PLWHA patients
Difficulty in Management of Advanced Pediatric Orbital Tumor
Authors: Sudrajat Nandang , Lutfi Delfitri 
Published: December 2021

Introduction: Tertiary care centers often manage pediatric orbital tumors, especially in advanced lesions and complex management. We report a case of a young boy with a malignant orbital tumor involving intracranial infiltration. Case presentation: A four-year-old boy had proptosis on the left eye for two months accompanied with blurred vision, pain, and oftenly bleeds with ipsilateral nasal congestion. There was no history of trauma, eye disorders, systemic diseases, or growth disorders. The physical examination showed stable vital signs, however a weak general condition and no enlarged regional lymph nodes. Visual acuity of the left eye was no light perception. There was a mass with protrusion of the left eye, swelling of the eyelid with an irregular surface, and a tendency to bleeds. The cornea was hazy with partly scarring, so we could not evaluate the posterior segment. MRI of the head presented a malignant soft tissue mass of the left orbital region with intracranial infiltration. The patient was given adjuvant chemotherapy; however, he could not survive due to systemic complications. Conclusions: The definitive diagnosis for the orbital tumor is obtained by histopathological examination. The investigation with CT scan or MRI imaging could be considered if not possible. However, since the definitive diagnosis still not assessed, the management can be affected. It is essential to have a definitive diagnosis to provide adequate treatment for the patients. Delayed and inadequate management can make malignant orbital tumors potentially life-threatening.

Abstract
A moving water mass generates force which is exerted on its moving path. Cyclone generated storm surge or earthquake generated tsunami are specific examples of moving water mass the generates force along the coasts. In addition to human lives, these moving water masses cause severe damages to the coastal infrastructure due to tremendous force exerted on these structures. To assess the damage on these infrastructures, an essential parameter is the resultant force exerted on these structures. To evaluate the damages, there is hardly any quantitative method available to compute this force. In this paper we have developed a semi-analytical model, named as Dynamic Force Model (DFM), by using Variational Iteration Method to compute this force. As governing equations, we have used the Saint Venant equations which are basically 1D shallow water equations derived from the Navier-Stokes equations. The verified, calibrated and validated DFM is applied in Bangladesh coastal zone to compute dynamic thrust force due to tropical cyclone SIDR.
