Authors: Şen Hilal Susam , Yalçın Bilgehan , Canpınar Hande , Ocak Süheyla , Akyüz Canan
Published: December 2020

Background. Infantile hemangiomas (IH) represent the most common type of benign tumors of infancy. Vascular endothelial growth factor (VEGF) and basic fibroblastic growth factor (bFGF) have a central role in the pathogenesis of infantile hemangiomas.
Methods. In this prospective study, we aimed to investigate the relationship between serum VEGF and bFGF levels and clinical characteristics and the serological changes in VEGF and bFGF levels associated with propranolol treatment in infants diagnosed with IH. Blood samples were taken from 34 patients with IH and 10 controls. Serum VEGF and bFGF levels were studied by ELISA.
Results. At initial diagnosis, median serum bFGF levels were 11.1 ng/ml (4.8-16.6) in patients with IH (n=34) and 2.6 ng/ml (1.7-4.7) in controls (p < 0.001), and, median serum VEGF levels for same groups were 58.5 ng/ml (25.3-190.2) and 11.4 ng/ml (8.2-19.8) (p < 0.001), respectively. Serum VEGF and bFGF levels were not correlated. In 18 infants who were treated with propranolol with serial measurements, median serum bFGF levels were 10.7 ng/ml, 9.8 ng/ml and 10.5 ng/ml (p= 0.8), and median serum VEGF levels were 68.6 ng/ml, 63.5 ng/ml and 45.1 ng/ml (p < 0.001) at initial diagnosis, at first and third months, respectively. Median regression rates of the hemangiomas at the first and third months were -%47.3 and -%58.3 (p < 0.001), respectively.
Conclusions. Serum bFGF levels didn`t change in time. Serum VEGF levels seemed to follow the natural course of IH and might be a marker for follow-up. The contribution of propranolol treatment should also be considered.
Is being small for gestational age a risk factor for strabismus and refractive errors at 3 years of age?
Authors: Petriçli İkbal Seza , Kara Caner , Arman Ayşegül
Published: December 2020

Background. Visual problems, cerebral visual impairment, refractive errors and strabismus are commonly found in preterm infants in long-term follow-ups. The aim of this study was to determine the factors that lead to the development of amblyogenic risk factors, such as high refractive errors, anisometropia and strabismus, in the long-term evaluation of preterm infants.
Methods. We retrospectively evaluated children who were screened for retinopathy of prematurity (ROP) and who had a 3rd year ophthalmologic examination. The impacts of sex, gestational age (GA), birth weight (BW), BW for GA, being small for gestational age (SGA), being appropriate for gestational age (AGA), multiple pregnancies and the results of ROP screening on refractive errors and the development of strabismus were evaluated by logistic regression analysis. The SGA and AGA groups were compared in terms of refractive errors and presence of strabismus.
Results. Six hundred and eight children, including 317 (52.1%) males and 291 (47.9%) females, were included in the study. The mean GA was 31 ± 3 weeks (24-36), and the mean BW was 1505 ± 435 g (600-2460). The number of SGA-born children was 101 (16.6%). Manifest deviation was detected in 42 (5.6%) children, and optical correction was required in 101 (16.6%) children. Being an SGA infant and multiple pregnancies were risk factors for refractive errors requiring optical correction, and hyperopia (≥3.00 D) was found to be a risk factor for the development of strabismus in the multivariate regression analysis. Additionally, the SGA group was at high risk for strabismus, hyperopia, high astigmatism and the need for optical correction.
Conclusions. We concluded that SGA seems to be associated with an increased risk of strabismus and a high refractive error. It should be taken into consideration during follow-up examinations of SGA infants.

Locating Human Security In the City: The Case of Rohingya Refugees In New Delhi
Authors:   ,   Southern Methodist University, Patel Ashvina
Published: December 2020

This research examines the subjective experience of human security by Rohingya urban refugees who fled to New Delhi, India, from Myanmar, in 2012. It uses bottom-up, top-down, and historical-to-present approaches to recognize the myriad factors that influence the path to security. The bottom-up approach frames the Rohingya present-day experience; the top-down approach delineates motivations embedded in the current India state and the international refugee regime; and the past-to-present approach explains the perspectives of each of these actors. One urban refugee settlement was chosen as a primary field site to examine the challenges and varied everyday experiences of the city for migrants. Two other urban settlements were selected for supplementary participant observation and the collection of quantitative data. At my primary field site, Rohingya men and women were interviewed to assess their feeling of security (in Rohingya hefazat or in Hindi suraksha). The perceptions of United Nations High Commissioner for Refugees (UNHCR) employees, government officials, and community representative were also recorded. Human security, defined as a person-centered security, was assessed on three dimensions: political, economic, and community. Analysis of the data compelled me to focus on what I call political human security. Anthropologists theorize the embeddedness of new immigrants and resettled refugees through acts of cultural citizenship, assimilation, and integration. This study, however, demonstrates that for urban refugees their primary need is basic security. This security is inevitably political; Rohingya refugees are deemed “illegal” immigrants by the state, but are permitted to stay as protected wards of the UNHCR. They assume a refugee identity that both expose them to further exploitation, while also shielding them from starvation and disease. This politically formed identity must be negotiated in daily interaction in order to find security. India is a first country of asylum for the Rohingya in this study. No South Asian country has signed the 1951 Refugee Convention or its 1967 Protocol, making India a good case study for how South Asia may respond to refugee influxes into urban spaces. India is unwilling to allow Muslim refugees to become naturalized citizens, pointing to religious and cultural factors that produce insecurity in the South Asia region. Furthermore, tensions rise when apolitical agencies like the UNHCR call upon India’s conservative administration to protect a population they define as undesirable. By focusing on urban refugees and their interactions with the state and supranational organizations, this research demonstrates the importance of statehood and citizenship as instruments of sovereignty that uphold human rights and protect against insecurity.
“I Am Not My Illness!”: Navigating the Mental Healthcare System in New Orleans
Authors:   ,   Southern Methodist University, Mehmood Saira
Published: December 2020

This research examines the experiences of individuals diagnosed with chronic mental illnesses and how they navigated the mental healthcare system in New Orleans, Louisiana. To realize the main research objective, I analyzed how individuals with chronic mental illnesses perceive mental illness and stigma; the services individuals use to address their mental health needs and the barriers they face in this process; who individuals disclose their mental illness to and under what contexts; and how individuals diagnosed with mental illness and their caregivers understand and embody recovery. Situated between medical anthropology and urban anthropology, it examines the challenges individuals diagnosed with chronic mental illness and caregivers encounter in utilizing mental health services. Using critical race theory and studies on whiteness, I analyze the intersectional identities of individuals to understand how various axes of identities such as race, gender, age, and religion affect how people utilize mental health services, conceptualize stigma, how this is related to disclosure, and what recovery means to them. While I use stigma scales to measure various types of stigma, I triangulate this data with observations from participant-observation and interviews to reconceptualize stigma in what Tyler and Slater (2018) argue for approaching the social and political dynamics of stigma and acknowledging history. I do this through the use of stigma syndemics. Central to this is the role of mental health professionals and other key stakeholders, and how they interact with individuals utilizing community mental health services. I examine how past experiences such as trauma and incarceration limit access to housing programs, employment, and how this affects recovery. Lastly, I argue that for effective advocacy on mental health to occur, synergistic activism through coalition building needs to transpire between all the entities that affect individuals who have mental illnesses.
Women’s Experiences With Maternity Care and Medical Discourse In Florence, Italy
Authors:   ,   Southern Methodist University, Wallerstedt Michaela
Published: December 2020

This dissertation is based on ethnographic research in Florence, Italy. The primary focus of this research is based on a comparison of medical discourse from Italian State documents with women’s experiences during pregnancy and childbirth in Italy. Mirroring trends throughout the developed world, Italy has maintained high rates of cesarean sections since the turn of the century. Italy’s unique political and cultural history has made Tuscany one of the best regions for maternity care within a country with significant regional variability. This dissertation looks at historical and current cultural trends to understand the ways in which women experience high-quality maternity care in Florence. This dissertation interrogates women’s experiences during pregnancy and childbirth through the theoretical lenses of political philosophy, agency and practice theory, and the medicalization of reproduction. This dissertation provides new avenues through which to draw connections between these three social theories. Medical discourse in the State documents demonstrates the ways in which women’s subjectivities and experiences are erased in an effort create a population upon which it is (theoretically) easier to enact interventions. Discourse ignores women’s agency in favor of implying that doctors and healthcare professionals are far more important actors in pregnancy and childbirth. But Italian women assert their own agency against medicalized birth through their reproductive socialities. By making connections with other mothers and midwives, women find support beyond medicalized models of maternity care. Local hospitals and healthcare clinics become sites that foster reproductive sociality. Women seek out care from healthcare professionals, primarily midwives, not due to their medical competence but due to their ability to create relationships with their patients. Midwives are part of what makes hospitals the ideal place for birth; a safe haven from the potential risk of birth. This idealization of birth, however, often gives way to less than desired care, demonstrating the fractures and inconsistencies in the way midwifery-based care is perceived. These fractures and inconsistencies are also seen in how women conceive of healthcare throughout the country. Women themselves simultaneously value and devalue their own socialities. Women’s discussion of the Italian healthcare system demonstrates how deep-seated ideologies of rationalist medical behaviors and stereotypes about the South. Women afford flexibility in departing from ideal modes of birth in their own decisions, but do not afford women the same flexibility in the South. Medicalized rhetoric seeps into deep seated beliefs about the South, demonstrating that women’s own positive experiences are not always valued as a means to achieving quality healthcare. Through analyzing the connection medical discourse and women’s reproductive sociality, I demonstrate the tenuousness with which experience is valued.

The article deals with the issues of providing communication, as well as diagnostics and telemetry of freight cars. The growth of rail traffic is currently placing increased demands on the levels of safety, automation and an increase in the average speed of freight trains. These requests can be solved through the introduction of modern GSM communication systems and geolocation. At the present time, a system for detecting the descent of a freight car has been developed and is being tested, which makes it possible to record the descent within a few seconds and transmit a signal to the train driver via a radio channel. The systems for monitoring the location of wagons and locomotives are no less important. However, one of the current problems is the lack of autonomous power supplies for communication and diagnostic systems. Since wired power systems have a number of disadvantages, the article discusses the creation of a power source based on an alternator with permanent magnets. This generator is driven by energy from a wheelset. The article presents the results of a numerical experiment on the magnetic system of axle-box generators using the ElCut software

When designing pipeline systems, the question of reducing the vibration load transmitted from vibroactive elements (pumping units, compressors, etc.) through the pipelines to the base almost always arises. In this case, as a rule, when laying pipes, one end is connected to a vibration source through flexible elements (bellows, elastic compensators, pipes). The pipeline is installed on hangers with vibration dampers. The paper considers the issues of calculating the mechanical resistance of flexible connectors, pipelines and vibration isolators of suspensions, as well as analytical dependences and the results of numerical calculation of the forces transmitted to the base and the radiated power depending on the frequency. The graphic materials show the frequency characteristics of the forces on the base and vibration power, depending on the considered mechanical system parameters

The article describes a method for constructing three-parameter bodies using a framework consisting of a set of non-rectangular portion quadrangles, in which opposite boundaries have different parametric lengths. Equations of degenerate portions of bodies constructed on a hexagonal, pentagonal, and four-cornered frameworks are given. All these portions can be combined in one model to form a composite body. An algorithm for determining control points for a cubic Bezier curve, used to construct a boundary curve of a portion of a body, is considered. This method allows you to simulate the shape and describe the behavior of intermediate surfaces inside the body of the simulated object. The proposed technique can be used in the numerical simulation of multilayer structures of variable thickness.
Assessment of fatigue among aviation personnel involved in military flying in India employing Multidimensional Fatigue Symptom Inventory – Short Form (MFSI-SF)
Authors: Mohapatra SS , Sarkar R , Ghosh DD
Published: December 2020

Introduction:

Fatigue has been recognized as a major safety hazard in modern aviation. There are numerous studies which have addressed various aspects such as the subjective symptoms, objective measures to diagnose fatigue, and its link with operator’s performance. This study was a novice attempt to assess the chronic fatigue among the aviation personnel employing “Multidimensional Fatigue Symptom Inventory – Short Form (MFSI-SF),” which is a well validated fatigue questionnaire.

Material and Methods:

A total of 93 aircrew and 30 ground crew of either sex from three military air bases were randomly selected for this cross-sectional observational study. The selected participants were requested to respond to 30 items listed in the survey form based on various types of symptoms along with severity that they experienced in the preceding 1 week.

Results:

The total fatigue score in case of the studied ground crew was higher than the studied aircrew group and this was statistically significant (P = 0.00001). The fighter, transport, and helicopter groups were not different from each other as far as their total fatigue score is concerned. However, ground crew group had significantly higher score in comparison to the score of the fighter, transport, and helicopter groups. In this study, 43.33% of ground crew participants and 11.82% of aircrew participants were observed to have fatigue. On stream-wise analysis, 2.94% of transport aircrew, 14.28% of fighter aircrew, 20.83% of helicopter aircrew, 52.17% Air Traffic Control (ATC) ground crew, and 14.28% of other ground crew who had participated in this study were fatigued.

Conclusion:

Fatigue in either form, i.e., acute or chronic, could affect both aircrew and ground crew. The present study had revealed that the proportion of ground crew suffering from chronic fatigue was more than the aircrew. The aircrew who were found to have such type of fatigue were younger in age and experience in comparison to their counterpart ground crew. Among the ground crew, a large percentage of ATC crew had this form of fatigue.
Cardiovascular dynamics among differently trained individuals during simulated microgravity exposure in the form of head-down tilt
Authors: Mandal S , Pipraiya R , Sinha B
Published: December 2020

Introduction:

Human morphology and physiology are not designed inherently to function in microgravity. Hence, exposure to hypo or microgravity, as it occurs during space exploration, poses challenges in the form of peculiar adaptive physiological processes in healthy astronauts. These changes may vary (to a certain extent) depending on type of physical fitness (namely, aerobic or anaerobic) and may have definitive impact on short duration space mission. The study aimed to examine the cardiovascular dynamics during short duration exposure to simulated microgravity condition in differently trained individuals.

Material and Methods:

Temporal variations in body fluid distribution were studied during 6° head-down tilt (HDT) for 4-hours in 31 healthy males in age range of 20–40 years divided into three groups based on their physical training, namely; resistance trained (RT), endurance trained (ET), and untrained (UT). This was based on their history of physical training, VO2 max, and peak anaerobic power.

Results:

Heart rate in the ET group and RT group showed increasing and decreasing trend respectively, however, statistically remained non-significant. Systolic and diastolic pressures showed a significant increase in the ET group at the 4th h of HDT as compared to baseline and the 1st h. No significant variation in pulse pressure could be seen. Mean arterial pressures showed significant increase in the ET group at the 4th h of HDT as compared to baseline and the 1st h of HDT. Stroke volume and cardiac output did not vary significantly.

Conclusion:

ET individuals in the present study demonstrated decreased sensitivity of baroreceptors than RT or UT individuals, whereas, the RT group demonstrated more stability/resilience in terms of cardiovascular dynamics than ET and UT groups under exposure to short duration simulated microgravity.

Wie werden Verfolgung, Flucht und Migration erinnert? Szenisches Verstehen in intergenerationalen Forschungssituationen
Authors: Inowlocki Lena
Published: December 2020

Wie über Migration, Verfolgung und Flucht zwischen Generationen in Familien erzählt und – szenisch – erinnert wird, kann Aufschluss über damit verbundene biographische und intergenerationale Leidenserfahrungen und Herausforderungen geben sowie über kollektive, zeitgeschichtliche, politische und institutionelle Dimensionen dieser Erfahrungen. Im Zentrum rekonstruktiver Sozialforschung steht dabei die Art und Weise, wie Geschehen und Erfahrungen erinnert, mitgeteilt und evaluiert werden; dabei kommt dichten Szenen in der Forschungssituation eine besondere Bedeutung zu. In intergenerationalen Interview- und Gesprächssituationen werden Forscher*innen, die sich auf offene Gesprächssituationen einlassen, in szenischer Form in Interaktionen und Aushandlungen involviert. Wie kann das in biographieanalytischen und ethnographischen Vorgehensweisen der Forschung reflektiert werden, und wie kann es Bestandteil der sozialwissenschaftlichen Lehre sein? Literarische Darstellungen und Filme zu intergenerationalen Perspektiven auf Verfolgung, Flucht und Migration können in der Forschung und in der Lehre für (selbst-)reflexives und szenisches Verstehen in der rekonstruktiven Sozialforschung sensibilisieren sowie dafür, wie wir „die eigene Geschichte“ verstehen können und im reflektierten Verhältnis dazu „die Geschichte anderer“.
GRAF PERFECT DAN GRAF IMPERFECT PADA BEBERAPA GRAF
Authors: Fransiskus Fran Zakiah, Helmi,
Published: December 2020

Graf perfect adalah suatu graf G dengan setiap  subgraf induksi dari G memenuhi ω(H)=χ(H), sedangkan jika terdapat H sehingga χ(H)>ω(H) maka G disebut graf imperfect. Terdapat beberapa graf yang pada kondisi tertentu merupakan graf perfect dan pada kondisi yang lain merupakan graf imperfect. Pada tulisan ini dibahas tentang graf perfect dan graf imperfect pada beberapa graf yaitu graf sikel (Cn), graf roda (Wn), dan graf helm (Hn). Untuk C3,C2n, n≥2, W3,W2n, n≥2, H3, H2n, n≥2 merupakan graf perfect, sedangkan untuk C(2n+1), n≥2, W(2n+1) ,n≥2, dan  H(2n+1) ,n≥2 merupakan graf imperfect. Kata Kunci : subgraf induksi, pewarnaan graf, bilangan clique, bilangan kromatik
PENYELESAIAN MULTIPLE TRAVELLING SALESMAN PROBLEM (MULTI-TSP) DENGAN METODE ORDER CROSSOVER DALAM ALGORITMA GENETIKA (Studi Kasus: Data Pelanggan Agen Surat Kabar di Kota Singkawang)
Authors: Yudhi Synthia Wulandari Helmi
Published: December 2020

Pendistribusian surat kabar oleh beberapa orang salesman pada suatu agen perlu meminimalisir rute yang ditempuh dari depot tertentu (agen surat kabar) menuju ke alamat pelanggan sehingga dapat diantar tepat waktu. Permasalahan dalam penentukan rute oleh beberapa orang salesman merupakan kasus dari Multiple Travelling Salesman Problem (Multi-TSP). Kasus Multi-TSP dapat diselesaikan dengan menggunakan Algoritma Genetika (AG). Algoritma genetika merupakan metode pencarian yang menggunakan tahapan operasi genetik dan seleksi alam. Pada proses penentukan rute terpendek dengan AG diperlukan langkah-langkah pembentukan populasi awal, penentuan nilai fitness, melakukan proses seleksi, melakukan operasi genetik (crossover dan mutasi), dan terbentuk individu baru. Proses AG menggunakan representasi permutasi untuk pendefinisian gen dalam pembentuk kromosom, pembentukan generasi awal menggunakan random generator, perhitungan nilai fitness. Proses seleksi dengan metode seleksi Roulette Wheel, operasi genetik (Order Crossover dan Swapping Mutation), sehingga diperoleh individu baru. Hasil simulasi dari agen surat kabar dengan probabilitas crossover sebesar 0,5 dan probabilitas mutasi sebesar 0,01 yang dilakukan oleh empat orang loper surat kabar ke 30 alamat pelanggan diperoleh rute terpendek dengan jarak 64,03 km pada generasi pertama. Kata Kunci : Rute Terpendek, Pelanggan Surat Kabar, Optimasi Kombinatorial
