Features of solving the inverse dynamic method equations for the synthesis of stable walking robots controlled motion
Authors: Gorobtsov Alexander , Andreev Andrey , Markov Alexey , Skorikov Andrey , Tarasov Pavel
Published: February 2019

The problem of walking robots controlled motion synthesis by the inverse dynamic method is considered. The inverse dynamic method equations are represented by the methods of multibody system dynamics as free bodies motion equations and constraint equations. The variety of constraint equations group are introduced to specify the robot gait, to implement the robot stability conditions and to coordinate specified robot links movement. The key feature of the inverse dynamic method equations in this formulation is the presence of the second derivatives of the system coordinates in the constraint equations expressing the stability conditions that ensure the maintenance of the vertical position by the robot. The determined solution of such equations in general case is impossible due to the uncertainty of the initial conditions for the Lagrange multipliers. An approximate method for solving the inverse dynamic without taking into account the inertial components in the constraint equations that determine the stability of the robot is considered. Constraint equations that determine the coordinate movement of individual robot links and required for unique problem solving based on approximate equations are presented. The implementation of program motion synthesis methods in the control system of the humanoid robot AR-600 is presented. The comparison of theoretical and experimental parameters of controlled motion is performed. It has been established that with the achieved high accuracy of the robot links tracking drives control with an error of several percent, the indicators of the robot's absolute movements, in particular, the angles of roll, yaw and pitch, differ from the programmed by 30-40%. It’s shown that proposed method allows to synthesize robot control in quasistatic mode for different movement types such as moving forward, sideways, walking on stairs, inclinations etc.

Military Collaboration and Nazi Printed Propaganda on the Territory of Crimea in 1941-1944 (Based on the Materials of Newspaper Golos Kryma)
Authors: Romanko Oleg
Published: February 2019

Introduction. This paper deals with the problem of military collaboration as a factor of Nazi printed propaganda in the occupied Crimea. It is emphasized that, despite its relevance, this problem has not yet become the object of scientific research. Methods and materials. The publication is based on a wide range of published and unpublished sources from Russian and foreign archives. The analysis of the coverage of the collaborationist theme is based on the materials of the Russian-language occupation newspaper Golos Kryma (‘Voice of Crimea’), which was published in Simferopol from 1941 to 1944 and was the basic printing body for the Nazi propaganda model implemented in Crimea. Analysis. With the help of general scientific and specific historical methods of research, as well as a systematic approach, the main theme of publications about the topic of military collaborationism, which were placed in the newspaper, is revealed. It is shown that until the spring of 1943 coverage of this problem was not systematic, for both Nazi propagandists and their local assistants. After the appearance of publications about the topics of the Vlasov movement and Russian liberation army, the coverage of the problem of military collaboration is changing radically. The reasons, which led to these changes, are specified. Results. It is argued that up to a certain point the forms and methods of presenting collaboration themes on the pages of the newspaper had an effective result. However, since the autumn of 1943, for a number of reasons, the force of their impact on the population fell sharply and has not restored.
Territory and Population of the Stalingad Region in 1939-1944
Authors: Sidorov Sergey
Published: February 2019

Introduction. The Stalingrad region was founded on the 5th of December 1936. In 1939-1944 the territory and population of the region underwent changes. It included a number of areas of the Volga German ASSR and the Kalmyk ASSR eliminated in 1941-1943. The Astrakhan district was transformed into an independent region, the Germans and the Kalmyks were deported to the eastern regions of the country.

Methods and materials. The author of the article uses statistical materials of the All-Union Population Census of the USSR of 1939 and the information and statistical reference book Stalingrad region (1939-1943). Figures and facts. A comparative historical method is widely used to reveal the peculiarities of the national composition of the population of the Stalingrad region and its neighboring regions, and to show the changes that took place in different areas of the region during 1939-1944. For the first time in research literature, 5 groups of rural areas of the region are distinguished.

Analysis. The national composition of the population of Stalingrad, Astrakhan and rural areas of the region is investigated, and a comparison with neighboring regions is conducted. Representatives of more than 80 nationalities lived in the Stalingrad region, among them Russians (87.6 %), Ukrainians (3.6 %), Kazakhs (3.2 %), Tatars (2.8 %) and Germans (1.0 %) prevailed. Special attention is paid to the change in the territory and composition of the region’s population after the annexation of 7 areas of the eliminated Volga German ASSR in 1941 and 2 areas of the eliminated Kalmyk ASSR in 1944 and the deportation of Germans and Kalmyks to the eastern regions of the country.

Results. The war led to a change in the national composition and a substantial reduction in the number of residents in the region. It took about 20 years to overcome the consequences of the war and deportation to restore the population of the Stalingrad region.
Forced Labor in Nazi Germany: Online Archive of Interviews and Related Educational Online Platform
Authors: Tausendfreund Doris , Timofeeva Natalya , Evdokimova Tatyana
Published: February 2019

Introduction.The article deals with the problem of forced labor in Nazi Germany during the Second World War. Despite the existence of profound scientific publications devoted to this problem in Russia and abroad, it still needs to be developed. The article emphasizes the urgency of its research in historical, anthropological and humanities perspective, because personal experience of those who survived after forced labor in Nazi Germany, must be stored in collective memory and comprehended by subsequent generations.

Methods and materials. Digital Humanities based on the method of oral history allows to solve this problem. The article presents two options of practical implementation of the issue: the online archive of the interview Forced Labor in 1939-1945. Memories and history and related online platform Learning based on interviews. Forced labor in 1939-1945. The archive includes about 600 narrative biographical interviews with victims of Nazi forced labor in 26 countries. The site accompanying the archive is now available in English, German, Russian and Czech. The second project is based on six specially selected interviews from the archive. Broad source base and nationally-oriented concept of forced labor in Nazi Germany, presented on the platform, create the historical context necessary for using this resource primarily in the secondary educational system of the Russian Federation.

Analysis and results. The article shows the possibility of using archive-interviews in science and education, and emphasizes that traditional and new methods of historical research can complement each other. The article emphasizes that biographical films created on the basis of interviews can make the memory of forced labor in Nazi Germany, first of all, of “eastern workers” and Soviet prisoners of war more visible in Russian cultural memory. Contribution of authors to writing an article. Characteristics of peculiarity of oral historical sources, online collections of interviews, compensation payments are given by D. Thousendfreund. Analytics of the project “Forced Labor 1939-1945. Memoirs and History “and online platform” Learning based on interviews. Forced labor 1939-1945”, as well as conclusions are prepared by N.P. Timofeev. Introduction, problem historiography and general editing of the article belong to T.V. Evdokimova.
International Legitimization of Russian Foreign Policy Actions in the Context of the Ukrainian and Syrian Conflicts: the ‘Responsibility to Protect’ Conception
Authors: Tarchokova Asiyat
Published: February 2019

Introduction. The complexity of foreign policy actions’ international legitimization is determined by the use of unilateral approach in the new environment of world political processes. Due to Russian foreign policy’s intensification, the issue of international legitimization of its foreign policy actions has expanded and deepened in the post-Soviet space and beyond: it is obvious in practice, but not conceptualized at the theoretical level.

Methods. It seems to be of utmost importance to consider the problem in the context of the recent most pressing events – the Ukrainian and Syrian conflicts, using the case-study method as well as through the perceptualhermeneutic analysis of foreign policy actions.

Analysis. The need to do research in legitimization as a process of justification and achievement of a foreign policy position’s recognition is obvious. It is necessary to highlight the reasons for the ineffectiveness of Russian foreign policy actions’ justification instruments and legitimization policy.

Results. The assessment and conceptualization of existing legal and political concepts is particularly important to build an international legitimization foreign policy strategy. The implementation of foreign policy action should be accompanied by the transfer of basic foreign policy values and interests, combining legal, political, and moral grounds. The improvement of the international legitimization mechanism, its tools’ rapid revitalization and operating flexibility can give Russia an indisputable advantage over other actors and allow it to ensure the necessary result for the foreign policy strategy and strengthen its positioning in the international environment.
The Nomadic World of the South of Eastern Europe in the 2nd - 1st Centuries BC (Eastern Innovations, Facts, Causes and Consequences)
Authors: Skripkin Anatoliy
Published: February 2019

Introduction. In the process of developing the chronology of early Sarmatian culture we have allocated the monuments dated by the 2nd - 1st centuries BC and characterized by their specificity both in the material culture and in burial rites.

Methods and materials. This article is devoted to the series of items from the Sarmatian burials of the 2nd - 1st centuries BC from the south of Eastern Europe having close analogies in the sites of Central Asia. The items are represented with different types of swords, bronze openwork belt buckles, latticed and gigantic belt buckles, clay cubic censers, miniature copies of boilers and quivers with bows.

Analysis. New features have been marked in the funeral rites. Burials in the decks got popularity, which had resemblance with the decks used in the burial practice of Tuva’s population of the last centuries BC. The percentage of northern orientation of the buried was significantly increased in some areas of the Volga and the Don regions. The analysis of the historical situation testifies to the migration of a number of nomadic groups away from China’s northwestern borders due to the aggressive policy of Xiongnu. This event caused the changes in ethnopolitical situation in Central Asia, the Greco-Bactrian kingdom ceased to exist due to nomadic attacks. The nomadic population of this region with the eastern elements in their culture had significantly increased. Great changes occured in the South Ural, the Volga-Don region and in the Northern Black Sea Coast, where the groups of nomads appeared which had not been mentioned in written sources before: Aorses, Siraki, Roksolans, Satarkhi. The occurred changes found reflection in written works of ancient authors.

Results. Thus, the events that took place on the northern borders of China, associated with the formation of the Hunnish nomadic empire, led to a significant change in the ethnopolitical situation up to the Northern Black Sea Coast region.
Clay Raw Material of Medieval Pontic Amphorae (to the Question about Production Areas)
Authors: Sukhanov Evgeniy
Published: February 2019

Introduction. Amphorae is a significant part of pottery from the early medieval sites of Pontic region. They are traditionally considered as important source for analyzing the chronology, directions and intensity of ancient trade links. The paper is devoted to comparative analysis of clay raw material used for making medieval pontic amphorae. These ceramic containers are wide spread in the sites of the 8th - 10th centuries in Crimea, Taman, the Don and the Volga river basins and in other areas.

Methods and materials. Two groups of sources were investigated. The first group contains samples from 280 amphorae found on settlement sites of Saltovo-Mayaki times in the Middle and Lower Don basin. These samples have been сollected by the author in the museum funds of Southern regions of Russia. The second group is represented by samples of clay raw material from Southern part of Crimea where pontic amphorae production centers were located (the foothills and Southern coast). We used A.A. Bobrinsky’s method for determining different regions for digging of main plastic raw material by analyzing the ceramic under a stereoscopic microscope.

Results. The main result of study is allocation of two kinds of raw materials which were used for pontic amphorae making (about 84 % of studied vessels). After comparing these raw material kinds with Crimean samples, their connection with different areas was clarified. These areas belong to different geological formations. The first area is in the South-Western Crimea, and the second area covers the Southern and South-Eastern Crimean coast, to the South of the ridge of the Crimean mountains. The conducted research allowed obtaining interesting data which need to be further proved by the methods of archaeometry.
The Results of Studying the Technique of Making Golden Horde Products Made of Non-Ferrous Metals (from the Collection of the Volgograd Regional Museum of Local Lore)
Authors: Kovaleva Kseniya
Published: February 2019

Introduction. The article is devoted to the results of tracing research of things made of non-ferrous metals from the collections of Tsarevskoe, Vodyanskoe, and Mechetnoe settlements, stored in the funds of the Volgograd regional museum of local lore.

Method. The author used the method of tracing. The digital microscope DigiMicro 2.0. was used to record the results of observation.

Analysis. The author studied 63 products and allocated two large groups: 1) cast products and 2) forged products. The study fixed the following operations for cast products: the use of open and closed molds, casting in composite forms, casting by the smelted model, by the impression, liner casting. In group 2, the following methods of forging were singled out: forming forging, punching, drawing and forging of wire, bending, drawing, twisting, hacking, cutting. Soldering was used to connect the elements. After forming, most of the products passed the subsequent processing associated with the removal of defects (primarily post-casting) and the application of decor (hammering, engraving, stamping, polishing). In addition, the decor could be formed during the creation of the mold (cast decor).

Results. As a result of the study, it was noted the use of a wide range of techniques and operations with a comparative technological simplicity for most products. It was also noticed that a few things have been specially prepared for the processing, and it demonstrates the use of secondary raw materials.
Redes sociales y promoción de destinos turísticos termales de la Eurorregión Galicia-Norte de Portugal
Authors: Sanchez Amboage Eva , Martínez Fernández Valentín Alejandro , Juanatey Boga Oscar , Rodríguez Fernández María Magdalena
Published: February 2019

La eurorregión Galicia-Norte de Portugal conforma el territorio con más recursos termales de Europa, lo cual ha posibilitado la construcción de un elevado número de establecimientos termales, referentes en su sector. Ante el escenario de constante cambio y evolución que ha experimentado el Turismo Termal, las Tecnologías de la Información y Comunicación (TICs) han sido relevantes para optimizar y mejorar la gestión y comercialización de su actividad turística. La presente investigación analiza la importancia de las redes sociales como medio de promoción del turismo termal a través de la opinión de los responsables de los establecimientos termales de Galicia y del Norte de Portugal. Las entrevistas estructuradas a los gestores de los balnearios indicados ha sido la técnica empleada para extraer la información necesaria, la cual se ha apoyado en el uso de la herramienta de análisis cualitativo y cuantitativo MAXQDA 2011. Los resultados evidencian que, si bien la mayoría de los responsables de los balnearios entrevistados coinciden en destacar la importancia de las redes sociales en la promoción online de sus respectivos establecimientos, se aprecia un desinterés generalizado en lo concerniente a su utilización.
“Who Does Not Dare, Is a Pussy.” A Textual Analysis of Media Panics, Youth, and Sexting in Print Media
Authors: Korkmazer Burcu , Bauwel Sofie Van , Ridder Sander De
Published: February 2019

The social media use of young people has become a site of increasing public interest. Young people experiencing with sexuality and intimacy in digital media spaces, has evoked public debates on youth, sexuality and social media. Sexting in particular, has often been covered in print media articles as a ‘risky’ youth phenomenon, leading to media panics about the alleged risks of social media. Although the social media use of young people has been studied in previous research, there remains a need to understand the broader cultural discourses on youth, sexuality and social media in print media. With this article, we examine the discourses in news stories covering sexting. The qualitative research design of this paper exists of a textual analysis of print media articles. Our findings show that public discourses in newspapers and magazines mainly articulate youth sexting as a deviant behavior. This deviance discourse is strongly linked to a gendered representation of youth who engage in sexting, resulting in a victimization of girls and criminalization of boys. The article concludes that the binary discourse in print media may not only reinforce sexual double standards, but also leaves little space for a more diverse and active comprehension of sexting.
The Inner Circle of Power on Twitter? How Politicians and Journalists Form a Virtual Network Elite in Finland
Authors: Ruoho Iiris Annikki , Kuusiplao Jaana
Published: February 2019

Top-level politicians and political journalists have been key actors in public discussion necessary for a democratic political system and transparent political decision-making. This article presents an empirical social network analysis showing the connections between Finnish top-level politicians and political journalists on Twitter and the construction of mediated political and media elites in this specific context. The article argues that there is a need to take seriously the Twitter as a medium and the new ways of networking provided by the digital, hybrid media environment in particular. The results of our empirical study suggest that it may even be relevant to talk about mediated elites, which have emerged under the new social condition created by the digitalization of media, culture, and society.
An Empirical Review on the Effects of ICT on the Humanist Thinking
Authors: Hermida Olivia Velarde , Casas-Mas Belén
Published: February 2019

The present article shows the results of a content analysis of scientific publications with two main goals – firstly, it is aimed at identifying the way the implications of ICT in dynamics that impact on the humanisation and dehumanisation of our societies are perceived in scientific publications. The second goal is to check if such representations provide continuity to the humanist thinking existing in the historical periods prior to the emergence of ICT. The content analysis is applied to the identification of narrative structure typologies with different arguments. A total of 136 different types of representations have been identified by applying the Systems Theory designed for the sampling of non-redundant systems. They are analysed with logical and structural methodologies that systemise the representations depending on whether they refer to socio-genetic or anthropo-genetic dynamics. The expected effects are identified, and it is verified that – in most cases – they will be considered both humanising and dehumanising. It is concluded that, as regards to the history of ideas, many humanist representations have continuity – they are still in force because they reflect persistent problems which remain unresolved; and there is a breakdown with the humanist thinking proposed by post-humanisms, which propose genetic and digital interventions that alter human nature.

We examined the impact of 24 preclinical and trial design variables for their influence on 132 phase II pediatric oncology clinical trials. Success was determined by an objective assessment of patient response, with data analyzed using Fisher's exact test, Pearson's chi-square test, and logistic regression models.

Results

Trials that evaluated patients with a single histological cancer type were more successful than those that assessed multiple different cancer types (68% vs. 47%, 27%, and 17% for 1, 2–3, 4–7, and 8+; p < .005). Trials on liquid or extracranial solid tumors were more successful than central nervous system or combined trials (70%, 60%, 38%, and 24%; p < .005), and trials of combination therapies were more successful than single agents (71% vs. 28%; p < .005). Trials that added therapies to standard treatment backbones were more successful than trials testing novel therapies alone or those that incorporated novel agents (p < .005), and trials initiated based on the results of adult studies were less likely to succeed (p < .05). For 61% of trials (80/132), we were unable to locate any relevant preclinical findings to support the trial. When preclinical studies were carried out (52/132), there was no evidence that the conduct of any preclinical experiments made the trial more likely to succeed (p < .005).

Conclusion

Phase II pediatric oncology clinical trials that examine a single cancer type and use combination therapies have the highest possibility of clinical success. Trials building upon a standard treatment regimen were also more successful. The conduct of preclinical experiments did not improve clinical success, emphasizing the need for a better understanding of the translational relevance of current preclinical testing paradigms.

Introduction

To reduce health care costs and improve care, payers and physician groups are switching to quality-based and episodic or bundled-care models. Disease progression and associated costs may affect these models, particularly if such programs do not account for differences in disease severity and progression risk within the cohort. This study estimated the incremental cost of disease progression in patients diagnosed with chronic lymphoid leukemia (CLL), acute myeloid leukemia (AML), and non-Hodgkin's lymphoma (NHL) and compared costs among patients with and without progression.

Methods

This was a retrospective study using U.S. administrative claims data from commercial and Medicare Advantage health care enrollees with evidence of CLL, AML, and NHL and systemic antineoplastic agent use from July 1, 2006 to August 31, 2014. Outcome measures included disease progression, 12-month health care costs, and 3-year cumulative predictive health care costs.

Results

Of 1,056 patients with CLL, 514 patients with AML, and 7,601 patients with NHL, 31.1% of patients with CLL, 63.8% of those with AML, and 36.9% of those with NHL had evidence of disease progression. Among patients with CLL and NHL, adjusted and unadjusted health care costs were significantly higher among progressors versus nonprogressors. Per-patient-per-month costs, accounting for variable follow-up time, were almost twice as high among progressors versus nonprogressors in patients with CLL, AML, and NHL. In each of the three cancer types, the longer disease progression was delayed, the lower the health care costs.

Conclusion

Progression of CLL, AML, and NHL was associated with higher health care costs over a 12-month period. Delaying cancer progression resulted in a substantial cost reduction in patients with all three cancer types.

Implications for Practice

Data on the rates and incremental health care costs of disease progression in patients with hematologic malignancies are lacking. This study estimated the incremental costs of disease progression in patients diagnosed with chronic lymphocytic leukemia, acute myeloid leukemia, and non-Hodgkin's lymphoma and compared health care costs in patients with and without evidence of disease progression in a real-world population. The data obtained in this study will assist future studies in quantifying the cost impact of decreased progression rates and will inform payers and physician groups about setting rates for episode and bundled payment programs.
Centrifuge model tests of earthquake-induced submarine landslide

Submarine landslides can cut off seabed pipelines and cables and destroy near-shore structures. Such processes can result in tsunamis, which inflict additional enormous damage in near-shore areas. To date, no modelling experiments have been able to simulate and clarify the conditions necessary for the occurrence of submarine landslides, their gravity flow transition and sedimentation. This study examined the submarine landslide of sand and silty sand induced by earthquake and liquefaction. First, similitude laws pertaining to a submarine landslide in a centrifuge were considered, and the conditions to produce a landslide in a centrifuge were investigated by using various types of test cases. The key factors were the combination of natural water and sand mixed with a significant fine fraction, including the osmotic pressure. In addition to these, the embankment slope failure followed by gravity flow, transition to flow, properties of flow and water-level fluctuation induced by ground failure were examined in detail. The debris flowed not with simple shear, but as a clod of soil similar to fluid, which encourages high-speed flow. Turbidity could be observed above the debris front body, and the fine fraction was deposited on the surface of the debris. The embankment slope failure induced water-level fluctuation.

Published: February 2019

The pool of key neuromediators and some neurotransmitter amino acids in cerebellum, hypothalamus and midbrain of rats exposed to chronic and different variants of interrupted alcohol intoxication was investigated. The most pronounced changes were recorded in midbrain. Chronic alcohol intoxication caused an increase in the concentrations of tyrosine, dopamine, 3,4-dihydroxyphenylacetic acid (DOPAC), noradrenaline, tryptophan, serotonin, GABA and aspartate in this part of the rat brain. Interrupted alcohol intoxication with 4 days interval is accompanied by an increase in the content of tyrosine, and noradrenaline. Interrupted alcohol intoxication with 1 day interval leaded to an increase in the concentrations of tyrosine, DOPAC, noradrenalin, tryptophan, GABA, glycine and aspartate. The amino acids composition “Titacin” had a pronounced normalizing effect in the midbrain under interrupted alcohol intoxication with 1 day interval.

The ultraviolet (UV) B-induced damage of the eye surface of experimental animals (rabbits) includes loss of corneal epithelium, apoptosis of keratocytes and stromal edema. These changes are accompanied by clinically and histologically manifested corneal inflammation, neutrophil infiltration, and exudation of the anterior chamber of the eye. According to mass spectrometric analysis, UV-induced corneal damage is associated with pronounced changes in the lipid composition of tears, including a decrease in the amount of arachidonic acid and prostaglandin E2 and an increase in the concentrations of prostaglandin D2 and its derivative 15d-PGJ2. In addition, it is accompanied by an alteration in the levels of hydroxyeicosate tetraenic acid derivatives, namely upregulation of 12-HETE and downregulation of 5-HETE. The revealed changes indicate the activation of metabolic pathways involving 5-lipoxygenase, 12-lipoxygenase, cyclooxygenase 1 and 2, and prostaglandin-D-synthase. These findings contribute to understanding mechanisms of UV-induced keratitis and point on feasibility of selective anti-inflammatory therapy for improving corneal regeneration after iatrogenic UV damage.

Using genetic engineering methods the expression vectors structures have been designed to produce recombinant proteins TnaCheY and Tna CheY-mut, the homologues of the chemotaxis protein CheY from the hyperthermophilic organism Thermotoga naphthophila in Escherichia coli BL21(DE3) cells. The cultivation conditions of transformed strains were optimized. The influence of episomal expression of the heterologous chemotaxis protein CheY on growth kinetics parameters of the culture of mesophilic bacteria E. coli was studied. The optimal purification flowchart of the obtained proteins using thermolysis is proposed. Using the E. coli BL21(DE3) laboratory strain as an example, the possibility of employment the episomal expression of such proteins to control the cultivation and production time of pharmaceutically and industrially valuable metabolites due to the impact on some stages of the bacterial chemotaxis is experimentally proved.

Background: The management of critically ill obstetric patients presents a unique challenge. Dedicated High Dependency Unit (HDU) and Intensive Care Unit (ICU) for obstetric patients are widely available in India. The data regarding obstetric critical care is invaluable in formulating policy decisions. The objective is to study the profile of cases admitted to obstetric HDU and ICU and to evaluate maternal outcome and co-morbid conditions.Methods: This was a prospective observational study between January 2017 and June 2018.Results: Total number of obstetric admissions was 7966. Total admissions to obstetric ICU were 60. ICU cases accounted for 0.7% of all obstetric admissions and 1.1% all deliveries. Obstetric cases formed 1.6% of total ICU admissions. Number of admissions to HDU was 576. HDU cases accounted for 7.2 % of all obstetric admissions. HDU utilization rate was 11.32%. Hypertensive disorders of pregnancy (n=22, 33.3%), obstetric haemorrhage (n=18, 30%), septic abortion (n=2, 3.3%) were the most common conditions necessitating admission.Conclusions: Hemorrhage was the most common indication for admission to HDU. Delayed identification and referral were the important obstacles. There is a need for early booking at peripheral centres. Introduction of obstetric ICU and multidisciplinary approach has brought down the incidence of maternal mortality in present centre.

Background: Early onset neonatal sepsis (EONS) is caused mainly by organisms present in the genital tract. Maternal risk factors increase the incidence of EONS. This study was done to find out the association between one such risk factor i.e., multiple vaginal examinations and EONS.Methods: Case control study. 114 patients with three or more vaginal examinations after rupture of membranes were taken as cases and 114 patients with less than three vaginal examinations after rupture of membranes were taken as controls. All these babies were followed up for the development of EONS.Results: Of the 114 cases, 6 babies developed EONS. None of the babies in the control group developed EONS. So, 3 or more vaginal examinations after rupture of membranes in labour is significantly associated with early onset neonatal sepsis with p-value of 0.01305.Conclusions: Multiple vaginal examinations after rupture of membranes is a risk factor for early onset neonatal sepsis.
