Критерий периодичности непрерывных дробей ключевых элементов гиперэллиптических полей
Authors: Платонов Владимир Петрович , Федоров Глеб Владимирович 
Published: January 2020

Периодичность и квазипериодичность функциональных непрерывных дробей в гиперэллиптическом поле $$L = \mathbb{Q}(x)(\sqrt{f})$$ имеет более сложную природу, чем периодичность числовых непрерывных дробей элементов квадратичных полей. Известно, что периодичность непрерывной дроби элемента $$\sqrt{f}/h^{g+1}$$, построенной по нормированию, связанному с многочленом h первой степени, эквивалентна наличию нетривиальных S-единиц в поле L рода g и эквивалентна наличию нетривиального кручения в группе классов дивизоров. В данной статье найден точный промежуток значений $$s \in \mathbb{Z}$$ таких, что элементы $$\sqrt{f}/h^s$$ имеют периодическое разложение в непрерывную дробь, где $$f \in \mathbb{Q}[x]$$ - свободный от квадратов многочлен четной степени. Для многочленов f нечетной степени проблема периодичности непрерывных дробей элементов вида $$\sqrt{f}/h^s$$ рассмотрена в статье [5], причем там доказано, что длина квазипериода не превосходит степени фундаментальной S-единицы поля L. Проблема периодичности непрерывных дробей элементов вида $$\sqrt{f}/h^s$$ для многочленов f четной степени является более сложной. Это подчеркивается найденным нами примером многочлена f степени 4, для которого соответствующие непрерывные дроби имеют аномально большую длину периода. Ранее в статье [5] также были найдены примеры непрерывных дробей элементов гиперэллиптического поля L с длиной квазипериода значительно превосходившей степень фундаментальной S-единицы поля L.

Authors: Толоконников Лев Алексеевич 
Published: January 2020

В статье рассматривается задача рассеяния звуковых волн абсолютно жестким цилиндром с радиально-неоднородным изотропным упругим покрытием в плоском волноводе. Полагается, что волновод заполнен однородной идеальной жидкостью, одна его граница является абсолютно жесткой, а другая - акустически мягкой, законы неоднородности материала покрытия цилиндра описываются дифференцируемыми функциями, гармоническая звуковая волна возбуждается заданным распределением источников на сечении волновода. В случае установившихся колебаний распространение малых возмущений в идеальной жидкости описывается уравнением Гельмгольца. Колебания неоднородного изотропного упругого цилиндрического слоя описываются общими уравнениями движения сплошной среды. Для нахождения поля смещений в неоднородном покрытии построена краевая задача для системы обыкновенных дифференциальных уравнений второго порядка. Первичное поле возмущений представлено совокупностью собственных волн волновода. Давление рассеянного цилиндрическим телом поля ищется в виде потенциала простого слоя. Построена функция Грина для уравнения Гельмгольца, удовлетворяющая заданным граничным условиям на стенках волновода и условиям излучения на бесконечности. Функция плотности распределения источников ищется в виде разложения в ряд Фурье. Для нахождения коэффициентов этого разложения получена бесконечная линейная система уравнений. Проведено усечение бесконечной системы и ее решение найдено методом обратной матрицы. Получены аналитические выражения для рассеянного акустического поля в разных областях волновода.

Effects of Bariatric Surgery in Early- and Adult-Onset Obesity in the Prospective Controlled Swedish Obese Subjects Study
Authors: Kristensson Felipe M. , Andersson-Assarsson Johanna C. , Svensson Per-Arne , Carlsson Björn , Peltonen Markku , Carlsson Lena M.S. 
Published: January 2020

OBJECTIVE
Bariatric surgery is an effective treatment for obesity, but it is unknown if outcomes differ between adults with early- versus adult-onset obesity. We investigated how obesity status at 20 years of age affects outcomes after bariatric surgery later in life.

RESEARCH DESIGN AND METHODS
The Swedish Obese Subjects study is a prospective matched study performed at 25 surgical departments and 480 primary health care centers. Participants aged 37–60 years with BMI ≥34 kg/m2 (men) or ≥38 kg/m2 (women) were recruited between 1987 and 2001; 2,007 participants received bariatric surgery and 2,040 usual care. Self-reported body weight at 20 years of age was used to stratify patients into subgroups with normal BMI (&lt;25 kg/m2), overweight (BMI 25–29.9 kg/m2), or obesity (BMI ≥30 kg/m2). Body weight, energy intake, and type 2 diabetes status were examined over 10 years, and incidence of cardiovascular and microvascular disease was determined over up to 26 years using data from health registers.

RESULTS
There were small but statistically significant differences in reduction of body weight among the subgroups after bariatric surgery (interaction P = 0.032), with the largest reductions among those with obesity aged 20 years. Bariatric surgery increased type 2 diabetes remission (odds ratios 4.51, 4.90, and 5.58 in subgroups with normal BMI, overweight, or obesity at 20 years of age, respectively; interaction P = 0.951), reduced type 2 diabetes incidence (odds ratios 0.15, 0.13, and 0.15, respectively; interaction P = 0.972), and reduced microvascular complications independent of obesity status at 20 years of age (interaction P = 0.650). The association between bariatric surgery and cardiovascular disease was similar in the subgroups (interaction P = 0.674). Surgical complications were similar in the subgroups.

CONCLUSIONS
The treatment benefits of bariatric surgery in adults are similar regardless of obesity status at 20 years of age.
Apropriação dos sentidos na legitimação do espaço de devoção a Nossa Senhora Aparecida
Authors: Targino Eliana Aparecida , Abdala Rachel Duarte , Silva André Luiz Da 
Published: January 2020

O artigo procura discutir a fé e a magnitude que a imagem de Nossa Senhora possui por meio da visão dos indivíduos envolvidos no evento Tricentenário do encontro da imagem, promovido no ano de 2017 pelo Santuário Nacional de Aparecida, um dos locais de expressão do culto mariano no Brasil. Utiliza um recorte do trabalho de campo da pesquisa de mestrado de uma das autoras e objetiva analisar as manifestações devocionais, os significados que o espaço construído em torno da pequena imagem suscita e os envolvimentos dos indivíduos na Comemoração Jubilar dos 300 “anos de bênçãos”. A coleta de dados se deu por meio da observação das práticas devocionais e de entrevistas semiestruturadas durante a Festa de Nossa Senhora Aparecida, o que possibilitou ouvir e analisar relatos que retrataram a importância do culto, dos espaços e suas práticas devocionais e da identificação do povo brasileiro como parte importante do universo mariano. As homenagens prestadas neste lócus sacralizado são demonstrações de identificação de um povo que reverencia a virgem como Mãe, Rainha e Padroeira do Brasil. Além disso, é capaz de dizer que, para os entrevistados, Maria ocupa o lugar de modelo de perfeição e de mediadora, tendo um papel relevante na história da salvação da humanidade. Para eles, o sagrado se manifesta na religiosidade praticada no Santuário e a Virgem Maria endossaria um universo de crenças e práticas religiosas disseminadas pela Igreja Católica, mas não sem transformações.
Geografia, religião e mídia: novas interfaces do sagrado na era hipermoderna
Authors: Oliveira Jefferson Rodrigues de 
Published: January 2020

As novas conjunturas sociais e culturais possibilitam ao homem religioso ter acesso a diferentes mídias que proporcionam novas interações e conexões com o sagrado, gerando, assim, novos campos de análises e pesquisas sobre o universo midiático e do ciberespaço. Essas mudanças propiciam diferentes campos de pesquisa, em especial para a Geografia. Apoiado na tríade entre o homem, a tecnologia e o sagrado, as religiões se apropriam dessa novidade buscando, entre disputas políticas e econômicas, a manutenção de seus territórios religiosos e devotos. Buscando descortinar essas conjunturas hodiernas, o objetivo deste artigo será de apresentar ao leitor: a) a Geografia da Religião como campo de investigação em transformação; b) as novas transformações socioculturais na sociedade capitalista hipermoderna e; c) hipermodernidade digital, novos aportes teóricos e metodológicos na ciência geográfica. O campo de investigação empírico se dará através da IgrejaCatólica Apostólica Romana.

This study seeks to propose a plan for sustainable development in the management of the Olele Marine Park area as an educational-tourism area based on community empowerment. Qualitative research methods with data collection techniques through surveys, interviews and focus group discussions. The results of the study explain the potential for the development of marine tourism in Olele Marine Park, Bone Bolango Regency. Olele as one local sea park has a very large tourism potential if viewed from its diversity of marine life. As for the obstacles are the low quality of the management of the tourism sector management both in terms of infrastructure and human resource capacity. In addition there has been no synchronization between the roles of the government, the private sector and the citizens of Olele Village, so that the development of a sustainable tourism sector cannot yet be achieved. Olele Beach, in fact, does not provide large economic benefits to the residents of Olele Village. The competition of tourism service providers has made Olele Village residents unable to reap profits and advantages from tourism sector.

Published: January 2020

This study discusses the holding of an "event" which is an opportunity to overcome the situation of unsustainability tourism in Pantai Kelapa Patimban, Subang. Furthermore, this study explains the importance of coordination with various interested parties in organizing "events". Descriptive studies are used to examine more in depth the situation of the Patimban Coconut Coast which is in a crisis situation after the mega International Port development project began in 2015. The results of the study in the discussion section led to a number of interesting findings, including the fact that the "event" must consider many things and is not as simple as determining the "event" in what field, who is the event host, and who is the target participant / visitor. There are many factors that must be considered to support the smooth implementation of "events" starting from the stage of pre-preparation (event designing), preparation (event preparation), the implementation (event execution), and evaluation (event evaluation). These factors can be learned from other disciplines.The author hopes that through this writing, the author can provide ideas or ideas to bring back the Coconut Patimban Beach to sustainability tourism in the future.

Authors: Goh Seach Chyr (Ernest) , Siddiqua Sumi 
Published: January 2020

First year engineering students at the University of British Columbia Okanagan, take the Fundamentals of Sustainable Engineering Design course as part of the suite of common courses for all engineering students regardless of discipline. The largest assessment components of the course are the final exam (40%) and the design project (40%).
For the design project, teams of 4 – 6 students build a scaled-down prototype of a Well Ventilated yet Energy Efficient Room (WeVeyEER) that must be able to maintain its interior temperature at 10°C above ambient and at the same time continuously exchange stale air from within with fresh air from outside. It also has to meet load-bearing, size and power supply constraints. The energy consumption, rate of air exchange and weight are parameters for comparing performance of the prototypes.
The majority of teams (55 out of 64) could achieve the requirements. Feedback about the project was mixed, with 57 positive and 56 negative comments.
AUTOMATED STUDENT ASSESSMENT: LABEL RECOGNITION IN STEM FIGURES
Authors: Davis J. A. 
Published: January 2020

Visual representations such as Free body diagrams are an important part of solving engineering mechanics problems. Automatic Assessment of these types of images is difficult due to the involvement of multiple object types and to their contextual nature. Using a probabilistic approach, an algorithm was created to automatically categorize groups of characters in labels from images into specific object types including: variables, assignment operators, values, units, or words. Using these categories, the algorithm was then able to determine whether the label was an identifier, a point, a dimension, a variable definition, or an equation. A series of representative test cases were chosen and results found that the current algorithm was able to correctly predict the results of all test cases. The paper discusses each step in detail and provides the resulting probability coefficients for the model.
IMPACT OF LANGUAGE AND STRUCTURE OF INSTRUCTIONS ON STUDENTS’ CONFIDENCE TOWARDS COMPLETING ASSIGNMENTS
Authors: Hong Ran , Variawa Chirag 
Published: January 2020

First-year engineering students usually spend more time on courses assignments and projects that they perceived to be more difficult, which increases students’ workload and impacts their persistence in engineering programs. Students possess a higher level of confidence also tend to perform better on the tasks. Therefore, it is important to explore the impact of different aspects of assignment instructions on students’ perceived confidence, and establish a comprehensive set of guidelines for first-year course instructors and curriculum designers in instruction writing.
This research builds on existing first-year engineering student workload survey to identify the students’ confidence level on assignments in each first-year courses taught in University of Toronto. We compared assignment instructions in first-year engineering courses that students perceived to be difficult and easy, and conducted a focus group study to analyze students’ confidence level towards the same assignments but two different instructions. Observations suggest that students perceived assignments involving new concepts and complex problem context appear to be more difficult. Qualitative responses from students suggest that short instructions with explanations of course connections using plain language could increase students’ self-confidence towards completing these assignments.
Neurenteric cyst secondary to lumboperitoneal shunt
Authors: Mohammad Mohammad , Al-Khayat Hisham , Katchy Kenneth , Pejhan Shervin 
Published: January 2020

Background:
Neurenteric cysts are rare lesions that typically present in the upper thoracic and cervical spine and are occasionally found intracranially. The optimal treatment is gross total excision as subtotal/partial excisions are associated with high recurrence rates.

Case Description:
For the past 10 years, a patient with pseudotumor cerebri required repeated lumboperitoneal (LP) shunt revisions. This resulted in multiple neuroenterogenous cysts occurring around the proximal LP subarachnoid shunt catheter, a finding likely attributable to retrograde flow from the peritoneal cavity.

Conclusion:
Unlike ventriculoperitoneal (VP) shunts and LP shunts do not contain valves, making the retrograde passage of enterogenous cells possible when abdominal pressure exceeds lumbar subarachnoid pressure, especially in the morbidly obese patient.
