Социальные аспекты цифровизации детской городской мобильности
Authors: Сергеева Ольга Вячеславовна , Лактюхина Елена Геннадьевна 
Published: December 2019

Проникновение цифровой техники в повседневные коммуникации и пос­тоянная связь людей с техническими объектами порождает проблему «расцепления» – увеличения числа технических посредников в наших взаимодействиях. Эти изменения отражаются на повседневных практиках семьи: например, координация родителями пространственных перемещений детей опосредуется мобильным телефоном, навигатором, социальными сетями, приложениями для смартфонов. То есть практики детской мобильности в последнее десятилетие изменились, появилась интегрированная с цифровыми медиа «смарт-мобильность». В статье представлены результаты кейс-стади детской мобильности и ее контроля в трех российских семьях, где есть дети младшего и среднего школьного возраста. Использовались методы полуструктурированного интервью, рефлексивного отчета и картографирования перемещения детей. С опорой на идеи «поворота к пользователям» в рамках STS-подхода авторы рассматривают формирование социотехнической среды, регулирующей поведение ребенка в городе. Анализ пользовательских интерпретаций технологий проводился с учетом таких контекстов институциальной среды, как школа и дискурс о городских проблемах. На основании полученных данных обсуждаются вопросы закрепления этики технологического контроля в детско-родительских отношениях и привычки «быть наблюдаемым»; рассматривается сокращение и исчезновение самостоятельных перемещений детей в городе; анализируется смещение фокуса в детско-родительских отношениях с развития самостоятельности на ограничение приватного пространства ребенка; высказываются идеи о роли стратификационных факторов в поддержании интенсивной повседневной детской мобильности. Статья нацелена на понимание тенденций цифровизации и на проблематизацию ценности независимой детской мобильности.
«Место под солнцем»: уровни формирования школьной инклюзии
Authors: Горяйнова Александра Романовна 
Published: December 2019

Приоритетным направлением социальной политики развитых стран выступает активное вовлечение людей с инвалидностью в жизнь общества, в том числе в образовательный процесс. Трансформация государственной политики сопровождается внедрением и изменением нормативно-правовой базы, гарантирующей гражданские права людей с инвалидностью в различных сферах общественной жизни. В свою очередь реформы постепенно способствуют преодолению предрассудков со стороны общества к людям с инвалидностью, распространению практик взаимопомощи среди населения в реальной жизни. В сфере образовательной политики происходят преобразования, связанные с поворотом в направлении инклюзии. Формирование инклюзивной организационной культуры школ становится не менее важным условием обеспечения доступной среды, чем устранение архитектурных и технологических барьеров. Статья посвящена анализу основных ценностно-символических характеристик школьной инклюзии по материалам качественных интервью с учителями, учащимися и родителями. Эмпирическая база исследования состоит из полуструктурированных интервью с родителями, учениками, учителями, сотрудниками общеобразовательных школ, где обучаются дети с ограниченными возможностями здоровья и инвалидностью. В основе исследования концепция организационной культуры Эдгара Шейна, позволившая рассмотреть инклюзию на трех уровнях: артефактов, провозглашенных ценностей и базовых представлений. Анализ организационной культуры инклюзивных школ показал, что изменения на ценностном уровне транслируются от лидера другим участникам образовательного процесса, воплощаясь в наблюдаемых артефактах, практиках взаимодействия и непроговариваемых убеждениях. На культуру организации влияют и предпринимаемые инициативы «снизу», через паттерны поведения, провозглашаемые ценности и визуальные элементы поверхностного уровня культуры. Складываясь в процессе повседневного взаимодействия, организационные ценности, нормы и установки могут способствовать, а могут выступать барьером на пути преобразований. Разделяемые ценности связаны с принятием различий, индивидуальности каждого ученика в контексте солидарности органического типа, сплоченной и поддерживающей среды.
The Deep Meaning of Symbolism Significance in Men in the Sun
Authors: Elmahdi Omer Elsheikh Hago , Hezam Abdulrahman Mokbel Mahyoub 
Published: December 2019

The novel of MEN IN THE SUN by Ghassan Kanafani reflects the Palestinian cause, the 1948 catastrophe and its impact on the Palestinian people through Palestinian men of different generations who tell their story in a wonderful symbolic way. The novelist reflected the issue through the characters, as each character in the novel symbolizes a certain personality of his people. The story is the story of three men who decide to emigrate from Palestine to Kuwait illegally for their desire to improve their living conditions. The novel ends with the death of the three men suffocating for fear of beating the walls of the tank. This study is an attempt to examine the symbolism in Men in the Sun and its significance and the deep meaning behind the literal meaning of these symbols. The study tries to examine the basic symbol of the story "the walls of the tank are not pounded", as these three men die suffocating in the tank, without any of them daring to knock the walls of the tank for help. The symbolism of the non-knocking of the walls indicates the legitimate cry of the Palestinian people conflict, who have suffered from displacement. Other symbols in the novel are also analyzed to show how the writer used them for artistic and political purposes.

Published: December 2019

The study objectiveis to microscopically evaluate the morphology of sperm in patients with varicocele after surgical treatment and therapy with Prostatilen® AC.Materials and methods. The treatment group included 20 males between 26 and 45 years of age (mean age 31.6 ± 6.1 years) with various stages of varicocele and fertility problems; among them, 10 patients with subclinical stages of varicocele received conservative treatment with Prostatilen® AC (group 1) and were examined before and after the treatment; 10 males with infertility caused in part by varicocele of the spermatic cord veins were examined 6 months to 3 years after surgical treatment (group 2). Standard clinical and lab tests, sperm analysis, electron microscopy of the ejaculate were performed. The control group included 65 fertile males whose sperm samples were obtained from a bank of reproductive cells and tissues and used for comparison in microscopic examination.Results. In patients who received conservative treatment the number of sperm with immature chromatin decreased (p = 0.045) compared to the control group. This characteristic differed in patients after varicocelectomy and patients after conservative treatment (p = 0.037). Compared to control, the number of sperm with excess residual cytoplasm in the head and neck was higher in patients after varicocelectomy (p = 0.011). After conservative treatment, the number of sperm with excess residual cytoplasm was close to the control number and lower than in patients after varicocelectomy (р = 0.028).Conclusion.In patients with subclinical varicocele, conservative treatment with Prostatilen® AC leads to significant improvement in sperm ultrastructure compared to patients who underwent surgery to treat this pathology.

The study objective is to analyze the content of spermatozoa with single and double-stranded DNA breaks in different age groups.Materials and methods. The level of DNA fragmentation was studied in 300 ejaculate samples obtained from 266 sub- or infertile men. The group 1 included 150 samples obtained from 131 patients under the age of 45 (21–44 years), the group 2 included 150 samples obtained from 135 patients above the age of 45 (45–68 years). Mean ages were 34.8 ± 3.9 and 48.6 ± 3.1 years, respectively. The number of sperm with fragmented DNA was evaluated using the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method on ejaculate smears. The number of spermatozoa with >15 % of fragmented DNA was considered elevated. Standard semen analysis was performed in 117 and 97 men from the groups 1 and 2, respectively.Results. The number of sperm with fragmented DNA varied in ejaculated samples from 1.5 to 64.5 %. Mean number of sperm with DNA breaks in the group 1 (12.0 ± 6.0 %) was significantly lower than in the group 2 (16.1 ± 8.3 %, p <0.05). Mean sperm count in the ejaculate of the group 1 (267.0 ± 198.7 million) was significantly higher than in the group 2 (201.0 ± 162.9 million, p = 0.02).Conclusion. We revealed that in men over the age of 45 years, the percentage of spermatozoa with DNA fragmentation is higher than in men under 45 years of age, it may indirectly indicate an increased level of reactive oxygen species in the seminal plasma in older patients.

The objective is to present a clinical case of blunt trauma of the scrotum with a massive testicular crush. The presented nosology, methods of diagnosis and surgical treatment is highlighted.Clinical case. Patient, 18 years old, was admitted to the clinic with acute symptoms and complaints of pain and increased size of the right part of the scrotum. Questioning revealed that 48 hours prior the patient received a blunt injury of the scrotum. Ultrasound of the scrotal organs showed that in the right part of the scrotum testicle is not clearly differentiated, in the lower pole hypoechogenic signal is observed, no blood flow was evident using the color Doppler mode, but examination of the upper pole showed weak blood flow, the epididymis was partially differentiated. Hematocele was observed. The diagnosis of injury of the scrotal organs was confirmed, traumatic injury of the right testicle. Emergency surgery was performed: necrotized areas of the lower pole of the testicle were resected, plastic sealing of the upper pole of the right testicle to the epididymis was performed. Postoperative period was free of complications. The patient was discharged on day 6 after the surgery. Control ultrasound after 3 months showed that the right testicle was smaller, its echostructure was homogenous, blood flow in the testicular parenchyma was observed. Hormonal status, blood testosterone levels, ejaculate parameters were normal.Conclusion. The presented clinical observation confirms that organ-sparing interventions for massive crush injury of the testicle with minimal volume of viable tissue are possible but patient’s age and time after injury should be taken into account.
Temperature Control of a Small Volume-Thermal System in Heating and Cooling Processes with Arduino
Authors: BAYRAM Atilla 
Published: December 2019

An important field of the temperature control is
the identification of physical features of materials at a wide range of
operating temperatures. This paper presents the design of a temperature controlled
thermal system in heating and cooling processes. This system will be used in a
tension-compression testing machine. During the tensile experiments, the aim is
to keep the inside of the chamber at a desired temperature. The thermal system
consists of an isolated metal box, dry resistance, power regulator,
thermocouple, air fun, relay, amplifier, microcontroller and computer. For the
cooling processes in cryogenic temperatures, the system has also a solenoid
valve, DC motor driver and a liquid nitrogen tank. The temperature of the
chamber with a small bulk is controlled by a feedback system. This feedback
system measures the temperature with a K-type thermocouple and uses a
combination of a table-supported PID, P and on-off controllers to compensate
the errors between the reference and measured temperatures. In this setup,
Arduino is used as a microcontroller because it is simple, inexpensive and easy
to program. This card supplies all communication between the computer and the
experimental setup by a program written on the MATLAB with Arduino package for
real-time applications. According to the experimental results, the temperature
of the insulated chamber can be easily maintained between +450 oC
and –100 oC. The user defined
different temperature profiles were successfully performed on the setup and the
outcomes were compared with the mathematical model in the heating and cooling
processes. The deviations from the desired temperatures were found to be at an
acceptable level for the applications on a tension-compression testing machine.

Objetivos. Determinar la tendencia y factores asociados al cepillado de dos o más veces por día en niños menores de doce años entre el 2013 y 2018 en Perú. Materiales y métodos. Se realizó un estudio transversal mediante análisis secundario de datos reportados por la Encuesta Demográfica y de Salud Familiar. Se consideró la información de niños con al menos un cepillado al día, considerando como «Adecuada Frecuencia de Cepillado Dental» (AFC) para quienes reportaban de dos a más; se generaron medidas porcentuales por ámbito geográfico, características sanitarias, de vivienda y hogar. Se determinaron los factores asociados a la AFC mediante regresión logística binaria para encuestas complejas, la variabilidad de la tendencia se identificó mediante regresión joinpoint con un 95% de confianza. Resultados. En el 2013, la AFC fue del 79,0% con un aumento a 83,9% para el 2018; se identificó que cuatro de 25 espacios geográficos se mantuvieron sin variación de AFC, y otros cuatro disminuyeron. Todas las características sanitarias mostraron favorecer el cepillado, destacándose que el no compartir el cepillo generó un OR de 2,30, IC 95%: 1,46 a 3,60. La región natural, el tipo de lugar de residencia y el quintil de riqueza afectaron la AFC; la AFC fue mayor según se incrementa el grupo etario. Conclusiones. El porcentaje de AFC ha aumentado en los últimos años, siendo influenciado favorablemente por los aspectos sanitarios; a nivel rural este porcentaje es significativamente menor, algo que también se evidencia en la región sierra.

Development of Gel Phantom Having Dielectric Property Equal to Breast Tissue for Medical Metrology and the Effect of SiC Nanopowders on the Dielectric Constant
Authors: KARABEY Tarık , ERTUĞRUL Mehmet , EROĞLU Hayrettin 
Published: December 2019

There are major shortcomings of phantoms, which are important for
improving the image quality of medical devices produced by developing
technology and also for calibration settings. The most important of these
shortcomings is the change in the concentration of the structures forming the
phantom and the deterioration of the structure due to external factors. It is
important to design and develop gel phantoms which are longer time resistant to
these negative effects and show electrical properties close to the living
tissue. As is the case in many areas,
the use of live human subjects in the medical field has not been approved and
banned by many ethics committees due to the possibility of being harmful to
health, and instead of living human subjects, phantoms with close features are
used. In imaging systems, such as MR, Ultrasound, Tomography, X-ray, the
working range of these phantoms should be determined. In addition, the use of
mobile telephones has been widely used today, the absorption of electromagnetic
rays emitted from these devices (SAR) as a result of the loss of the electrical
property of phantom to determine the interval of distortion is important for
future advances and innovations in the medical field.

In the study, 5 g PVA was heated in a beaker containing 45 ml of pure
water for 5 minutes at 80oC with stirring and a 10% buffer PVA
solution was prepared. Different amounts of Triton X-100 were added to these
buffer solutions and mixed for 15 minutes. After waiting for 24 hours,
dielectric constants of gel phantoms were examined at room temperature. Agilent
85070E Network Analyzer and Performance Probe with Short Block were used to
measure the dielectric constant. Gel phantoms were obtained showing the
dielectric properties of human breast tissue according to the measurements
taken in the frequency range 0 to 20 GHz. 10 ml 10% PVA + 5 ml Triton X-100 gel
phantom from this gel phantom was examined by changing the dielectric constant
by mixing 0.1 g SiC nanopowder. Afterwards, images of this gel phantom obtained
with WETSEM (Wet Scanning Electron Microscope) were examined.
