Distributed Bayesian: A Continuous Distributed Constraint Optimization Problem Solver
Authors: Fransman Jeroen , Sijs Joris , Dol Henry , Theunissen Erik , De Schutter Bart
Published: January 2023

In this paper, the novel Distributed Bayesian (D-Bay) algorithm is presented for solving multi-agent problems within the Continuous Distributed Constraint Optimization Problem (C-DCOP) framework. This framework extends the classical DCOP framework towards utility functions with continuous domains. D-Bay solves a C-DCOP by utilizing Bayesian optimization for the adaptive sampling of variables. We theoretically show that D-Bay converges to the global optimum of the C-DCOP for Lipschitz continuous utility functions. The performance of the algorithm is evaluated empirically based on the sample efficiency. The proposed algorithm is compared to state-of-the-art DCOP and C-DCOP solvers. The algorithm generates better solutions while requiring fewer samples.
VARIATIONALLY DERIVED DISCONTINUOUS GALERKIN METHOD: APPLICATION TO DYNAMIC THERMOELASTICITY
Authors: Chen Pinlei , Masud Arif
Published: January 2023

This paper presents a variational approach for deriving discontinuous Galerkin (DG) method for coupled field problems. Starting from the variational multiscale discontinuous Galerkin (VMDG) framework that is applied to the mechanical and thermal fields across embedded interfaces, an interface DG method for the coupled multifield problems is developed. Extending the interface DG to all inter-element boundaries naturally leads to a full DG method. An important aspect of the proposed methods is that time dependency appears naturally in the analytical expressions for the Lagrange multipliers that enforce the continuity of the fields and their fluxes. Unique attributes of the analytical expressions are that they comprise material and geometric parameters that automatically embed the concepts of stress averaging and area averaging in the method. In addition, the interface terms also provide an avenue to variationally account for interfacial kinetic and kinematic models for a robust representation of interfacial physics in dynamic thermomechanical problems. The interface DG method where discontinuity in the fields exists only at the embedded interfaces while continuous formulation is employed in the rest of the domain is well suited for bimaterial interface problems as well as for obtaining computationally economic solutions to the general class of mathematically nonsmooth thermomechanical problems.
Several benchmark test cases are investigated that highlight the enhanced stability and variational consistency of the
proposed VMDG formulations.
Influence of steel fibre on bending behaviours of RPC based on X-ray CT and mesoscopic numerical simulation
Authors: Lu Juan , Zhang Yafang , Wang Qingxuan , Huo Yongjie
Published: January 2023

The mechanical properties and fracture mechanism of quasi-brittle materials are considered to be largely reliant on the mechanical properties of meso-components and the structure formed when these components are combined. In recent numerical simulation practice, a trend has developed whereby the real structure of materials is considered in as accurate a way as possible. In this paper, the macroscopic and mesoscopic bending behaviours of steel fibre-reinforced reactive powder concrete (RPC) slabs with fibre volume content between 0.0% and 2.5% were investigated using both experimental tests and numerical simulations. Images obtained from X-ray computed tomography (CT) were input into a program named RFPA3D-CT to build a modified three-dimensional finite-element method model. The results indicate that the steel fibres can help to convert a brittle failure pattern of RPC into a ductile one. Compared with specimens without fibres, the crack tortuosity and bending strength of specimens with fibre content of 2.5% are increased by 20.25% and 308.80%, respectively. The bending performance according to numerical results obtained by the modified model are in good agreement with the experimental results. Moreover, the acoustic emission (AE) parameters and AE curves obtained in RFPA3D-CT can be used to reveal the initiation and propagation process of cracks in RPC.
Medicina alternativa
Authors: Álvarez Ramírez Lorenzo
Published: January 2023

La homeopatía es una de las prácticas más utilizadas en la medicina alternativa, tanto en la atención de pacientes humanos como en veterinaria. Su origen se remonta a poco más de 200 años y su popularidad ha tenido altibajos desde entonces. Desde sus inicios y hasta la época moderna, los postulados de la homeopatía han sido motivo de debates en la medicina y en la ciencia. Conceptos aplicados en la homeopatía como el de similia similibus curentur, fuerza vital, dinamización, dosis mínimas o infinitesimales, y otras peculiaridades de la práctica, son poco reconocidos en la actualidad o incluso rechazados por completo. La debilidad del marco teórico de la homeopatía y la escasa evidencia seria que ha proporcionado dificulta su consideración como una herramienta de la medicina científica moderna. En la presente revisión de la literatura disponible, se describen de una forma crítica y rigurosa, los principios de la homeopatía, las evidencias experimentales de su funcionamiento, y su idoneidad en la medicina actual, para determinar si puede considerarse una práctica médica y veterinaria aceptable en el siglo XXI.

Published: January 2023

DOI:10.17014/ijog.9.2.229-246The alluvial water table of Wadi Nil is characterized by an abundance of groundwater, attributed to the high rainfall (1,000 mm/yr on average) of the region, the good permeability of its aquifer (10-3 to 10-4 m/s), and its significant thickness (35 to 100 m). Its waters are used for drinking water as well as for irrigation. In recent years (2000-2020), significant growth in terms of urban, agricultural, and industrial activities has developed on the plain, and has generated a significant amount of waste and effluents. In order to protect the groundwater resource, a map of the vulnerability of the water table to pollution, intended to guide public policies, has been drawn up. The DRASTIC method is a method chosen for the creation of this map, in view of its efficiency and reliability. The results obtained show that the groundwater consists of three zones: the first zone - of moderate vulnerability - is located in the outcrop areas of the marl formations (central part of the plain); the second - of high vulnerability - occupies most of the plain, composed mainly of the wadi alluvial formations; and finally the third - of very high vulnerability - is located in the downstream part of the groundwater, where the aquifer formations are sandy. The statistical analyses and sensitivity analysis of DRASTIC parameters highlight the importance of the parameters «water depth, recharge, and impact of the vadose zone» in the elaboration of the vulnerability map of the studied area, and show that the approach is relatively robust. Nevertheless, if the “water depth” and “recharge” parameters can be constrained by field measurements, the “impact of vadose zone” parameter appears to be the most delicate, because it is both sensitive and associated with uncertainties

Published: January 2023

DOI:10.17014/ijog.9.2.247-262Pore pressure prediction using velocity-mean effective stress relationship is introduced in Madura Subbasin which is located in a compressional tectonic setting. The new workflow accommodates the three principal stresses, those are vertical stress, maximum horizontal stress, and minimum horizontal stress in a form of mean stress as the compaction main inducing agent. The application of this new workflow has resulted in a more accurate pore pressure prediction where the normally used pore pressure prediction method tends to underestimate the actual data. In Dukuh-1 well, as an example, the pore pressure prediction from the new work flow is able to explain the continuous hole problems such as well flows and well kicks that were recorded during drilling. In MDA-2 well, the new pore pressure prediction closely matches the well data in comparison to the normally used prediction. As a result, a more accurate regional pore pressure prediction map using mean stress is generated to aid both hydrocarbon exploration and development activities in the study area

Authors:   Taras Shevchenko national University of Kyiv, Vyacheslav Shovkovy , Kirutsak Kateryna ,   Taras Shevchenko national University of Kyiv
Published: January 2023

Background: Well-developed listening skills of schoolchildren are significant for native language acquisition since these skills contribute to building the ability of perceiving, processing and transforming information in various communicative situations. The successful mastering of processing and transformation of information is a complex process which is affected by several cognitive factors: intelligence, reaction time, memory, attention span, and the ability to switch between different mental operations. One of the ways of transforming information is its compression. Teaching this skill integrated with listening is a challenging task that requires consideration of the age and individual psychological characteristics of schoolchildren, the pace of speech, the volume of the message, intonation features, etc. Purpose: The purpose of the study was to characterize the theoretical and practical aspects of the technique for teaching information compression integrated with listening to 5th-grade secondary school students in a Ukrainian language classroom. Results and Discussion: Compression of information in the process of listening is a mental process of processing a message which leads to the reduction of the speech signal, with the information preserved in the amount that corresponds to the communicative purpose of listening. Several types of compression to be taught in the 5th-grade Ukrainian classroom have been distinguished by the authors. The difficulties faced by students during the compression of information in the process of listening have also been specified. In most cases, they are related to the form of a language unit and communication, the form and volume of the message, dynamic features of the receiving channel, the semantic load of the message, etc. The criteria for selecting material for listening include content, structure and composition, genre, language, accessibility, listening length and time. Building the text compression skills is carried out at the text and post-text stages since compression is integrated with the stages of work on a text.
Strategic Management Acts in the Field of National Security
Authors: Zubarev S. M.
Published: January 2023

The article summarizes the views of legal scholars on the legal nature of strategic planning documents and supports the position on recognizing them as a type of political and legal acts. From the standpoint of the theory of administrative law, the presence in the documents of strategic planning in the field of national security of the main features of legal acts of governance is shown: by-law; state-governmental nature; legal nature; adoption by a competent subject of public authority; rule-making procedure for adoption. The definition of a strategic management act in the field of national security is formulated, which is proposed to be understood as an official document issued in accordance with the established procedure by the President of the Russian Federation or the Government of the Russian Federation and containing legal norms defining the goals, objectives, content and ways of implementing state policy to ensure and protect national interests and achieve strategic national priorities of the Russian Federation in the long term. It is precisely such acts that largely determine the architecture and content of the entire system of legal acts of management.

Published: January 2023

The article analyzes the most significant judgments of representatives of various branches of jurisprudence, expressed in the course of many years of discussion on the question, whether administrative offences are socially harmful or socially dangerous acts. The author considers this problem taking into account the provisions of modern legislation regulating the provision of various types of security, and the Code on Administrative Offences of the Russian Federation. At the same time, considerable attention is paid to the provisions of the National Security Strategy. It is argued that in modern conditions a significant number of administrative offences are socially dangerous acts, the commission of which leads to a decrease in the level of security of various types of human activity, creates a threat to the national security of Russia.

Authors: Troshev D. B.
Published: January 2023

The publication examines the specifics of the regulatory legal regulation of public administration activities under the unprecedented pressure of a number of foreign states on the Russian Federation, affecting to one degree or another, in fact, most areas of public administration. The author comes to the conclusion about the direct relationship of unfriendly actions of foreign states with threats to the sovereignty of the Russian Federation and the need for legal science to develop a universal legal mechanism for its administrative and legal protection in this regard.

The article examines the legislative acts that lay the legal basis for Russia’s response to unfriendly actions (including through the use of retaliatory measures) and the provisions of which are developed in subordinate law-making at various levels.

Based on the analysis of legislation and scientific doctrine, the peculiarities of public administration in the conditions of pronounced unfriendly actions of individual states are determined, and its main elements that are subject to study and improvement are also identified.
Public Administration and Regulatory Space in the Field of Artificial Intelligence
Authors: Ponkin I. V.
Published: January 2023

The article is devoted to assessing the completeness and quality of legal regulation in the field of artificial intelligence and legal support for the use of artificial intelligence in public administration. The author shows the state and development of artificial intelligence regulation in Russia.

The author shows that the segments of conceptual and doctrinal and strategic planning acts and the segment of standardizing documents in Russia have been created and filled to a certain extent in the country (at least purely formally), but there are no acts of legal regulation today, neither in a full-fledged modality, nor as some starting point.

The article reveals some key problems in the field of regulating the development, testing, implementation and use of artificial intelligence. The author raises the issue of separating the real developments of artificial intelligence technologies that are promising for use in public administration or are already being used or tested in this area, and outright deception in this area. The article proposes a mechanism for searching for appropriate solutions. The author proposes priority measures for completing the regulatory space in the field of artificial intelligence.
The Code of Administrative Offences as the Legal Basis of Administrative Responsibility in Germany and Russia (Material Aspects)
Authors: Politova E. U.
Published: January 2023

The author conducted a comparative legal analysis of the regulatory framework of administrative responsibility — the legislation on administrative offenses of the two countries that are part of the Romano-German legal family. It is noted that this legislation is codified in both countries. However, the German Code of Administrative Offences, unlike Russia, can be called a framework. The concept of an administrative offense and its signs are analyzed. It is noted that they partially coincide in Russian and German legislation. Special attention is paid to the analysis of subjects of administrative responsibility. In particular, there is an earlier age of bringing individuals to responsibility in Germany compared to Russia. It is noted that in Germany, unlike in Russia, the institution of complicity is used in administrative responsibility. Administrative offenses and administrative penalties applied for their commission in both countries are investigated. It is concluded that there are much more of them in Russian legislation and they are more diverse. In conclusion, the author makes proposals on borrowing certain provisions of the German Code of Administrative Offences in the Administrative Code of the Russian Federation.

Authors: Prokopov M. S.
Published: January 2023

The article examines the issues of digital transformation of federal state supervision in the field of road safety, forms and methods of its implementation. Special attention is paid to supervisory activities carried out without interaction with the controlled person — monitoring compliance with mandatory requirements and on-site examination. The conclusion is made about the importance of legislative consolidation of an exhaustive list of supervisory actions carried out within the framework of an on-site survey. The legal regulation of digital technologies of the federal state supervision in the field of road safety is in the process of formation. In the future, it is necessary to implement the possibility of self-examination using test sheets in automatic mode, the procedure of self-declaration, to ensure the appeal of decisions of the supervisory authority, actions (inaction) of officials in electronic form, etc. The digital transformation of federal supervision in the field of road safety should qualitatively change the system of state supervision, make it more open, shift the focus from punishment to prevention, reduce the costs of all stakeholders, and most importantly — reduce the number of accidents that occur due to violations of mandatory requirements.

Frequency-Dependent Velocity Changes of the 2018 Ms 4.5 Shimian Earthquake Revealed by Repeating Earthquakes
Authors: Zhou Cong , Shi Kexu , Zhang Pei , Zeng Xiangzhi , Zhang Meng
Published: January 2023

The wide application of seismic dense arrays has facilitated the monitoring of the coseismic velocity disturbance of small and medium earthquakes. In this study, a repeating earthquake cluster near the 2018 Ms 4.5 Shimian earthquake was relocated based on 10 groups of repeating earthquakes that occurred from 2013 to 2019, which were recorded by the Xichang seismic array. A repeating pair was obtained by estimating the overlap of the rupture region. Coda-wave interferometry was carried out in different frequency bands using the moving window cross spectrum and wavelet-domain trace stretching (WTS) methods. Our results show that velocity change at each frequency point can be obtained with the WTS method, and thus its frequency resolution is higher. In addition, the velocity changes of coda waves strongly depend on the frequency in the Shimian area, varying from +0.10% in the high-frequency band (5–10  Hz) to −0.23% in the low-frequency band (0.5–2 Hz). In particular, XC04, which is the station that closest to the epicenter, shows the largest velocity change in the low-frequency band, but the velocity change gradually decreases as the distance from the epicenter increases. It has been suggested that the low-frequency components of the coda waves of repeating earthquakes are more sensitive to medium variation. Combined with the earthquake relocation in the Shimian area, it was found that the normalized depth sensitivity calculated based on scattered waves can retain >10% sensitivity in the source area of the Shimian earthquake. Furthermore, the negative velocity changes calculated from low-frequency coda waves are likely attributed to the Shimian earthquake. It is recommended that the average interstation spacing of seismic dense array should be <30 km to facilitate the monitoring of the coseismic changes of small and medium earthquakes.
Detailed Imaging of a Seismogenic Fault That Potentially Induced the Two 2019 Weiyuan Moderate Earthquakes in the Sichuan Basin, China

Published: January 2023

Induced earthquakes are becoming a significant issue. Several destructive induced earthquakes (Ms ≥5.0) have occurred in shale gas fields located at the southwestern Sichuan basin, China, in the recent years. Specifically, two moderate earthquakes with magnitudes of Ms 5.4 (occurred on 8 September 2019) and 5.2 (occurred on 18 December 2019) exceeded the largest earthquake ever recorded in the Weiyuan. It remains unclear which seismogenic faults were responsible for the two moderate events due to insufficient knowledge of the subsurface structure and contradictory hypocenter depths obtained from different seismological methods. In this study, mainshock locations, focal mechanisms, and precise relocations of microseismicity were used to map the 3D geometry of the seismogenic fault. The result shows that the two moderate earthquakes occurred on the same fault. High-resolution seismic reflection profiles indicate several preexisting faults at various depths and a potential seismogenic fault. No large-scale faults are identified in the sedimentary cover above the Cambrian at the shallow centroid depth of these earthquakes. However, the seismic reflectors show phase discontinuous feature, indicating the existence of preexisting faults in the basement. A preexisting fault in the basement is consistent with a seismogenic fault that may have induced the two moderate earthquakes. Our study suggests that poroelastic stress propagation is likely responsible for the basement fault reactivation. The rupture on a stressed basement fault was triggered and produced two moderate earthquakes in a short period during hydraulic fracturing. The previous strategy of avoiding direct injection of fluids into preexisting faults to reduce seismic risk in operation region is not enough to avoid the possibility of the coupled poroelastic stress triggering deep fault rupture. We need to reevaluate the potential seismic risk of shale gas development in Weiyuan, the southern Sichuan basin shale gas field considering the preexisting faults in sedimentary and in basement and the effect of the fully coupled poroelastic stress field.

Published: January 2023

This report examines the following two questions: 1) do income-based differences in health and health care outcomes look the same for children with and without autism? and 2) do income-based differences in health and health care outcomes look the same for BIPOC (Black, Indigenous, and People of Color) children with autism and white children with autism? Examining the health and healthcare outcomes of children with autism in combination with other social characteristics offers several advantages. First, we can illuminate how demographics alone, and in combination with other social characteristics of children, are associated with differences in the rates of health and healthcare outcomes they experience. Second, it increases our understanding of the health-related experiences of social groups who are often neglected in research. Third, it provides current and comprehensive evidence on how children with autism experience relative disadvantages related to social determinants of health, which are aspects of the environment that affect health, functioning, and quality-of-life outcomes and risks.

Methods: A comparative cross-sectional study using simple random sampling to select 194 primary school children aged 6-13 years enrolled in two primary schools with (N=97) and without (N=97) school nutrition intervention in two upazilas in Rajbari district, Bangladesh. Data were collected from respondents with the assistance of guardians and teachers. Anthropometric data (height, weight, MUAC, body mass index for age Z score, height for age Z score, weight for age Z score,) were measured by anthro-plus software and overall data were analyzed by SPSS version 25.
Results: Of the total 194 respondents, the prevalence of stunting 9.3%, underweight 20.8%, thinness 27.8%, overweight 8.2%, and obesity 1.5% were observed. The prevalence of stunting 5.2%, underweight 21%, thinness 33%, and overweight 2.1% were found among the SFP group whereas 13.4% stunting, 20.5% underweight, 22.7% thinness, 14.4% overweight, and 3.1% obesity were found among without SFP group. The mean BMI-for-age Z scores were significantly lower (p=0.001) in the SFP group than in without SFP group. Socio-demographic characteristics may overrule this effect.
Conclusions: Findings suggest that determining the dietary pattern, and clinical signs and improving socio-demographic conditions may improve the nutritional status of the children with the school feeding program.
The effect of kangaroo mother care on stabilization of vital signs heart rate, respiratory rate and arterial saturation in low-birth-weight preterm babies
Authors: D. H. Deepak
Published: January 2023

Background: Kangaroo mother care (KMC) have positive effects on the preterm infant's health status in the form of stabilization of vital parameters. Therefore, this study was conducted to evaluate the effect of KMC on stabilization of vital signs in low-birth-weight premature babies.  
Methods: This is a quasi-experimental study. One hundred and seventy newborns who were admitted to in neonatal intensive care unit of Karnataka institute of medical sciences Hubli, India were selected by convenience sampling. They were randomly divided into experimental group, n=85 and control group, n=85. In the experimental group, newborns were taken daily KMC for four hours during 7 days. In the control group, routine care was performed. The data gathering tool was questionnaire of infants and mother characteristics, checklists of vital signs using SPSS 22 version software. Chi-square test was used as test of significance for qualitative data. Continuous data was represented as mean and SD. P<0.05 was considered as statistically significant.
Results: Before intervention, there was no significant difference between the vital signs of the infants in experimental and control groups. However, after intervention, there was a significant difference between the two groups in terms of vital parameters (p<0.001).
Conclusions: The findings of this study indicate the effect of KMC on stabilization of vital signs, it is recommended that KMC is taken as one of the routine cares of premature low birth weight babies.

Background: Iron is the most common micronutrient deficiency in pregnant women and infants throughout the world, mainly in developing countries like India. 30 to 50% of the pregnancies are affected by maternal iron deficiency and in developing countries, more than 80% of the pregnant women are estimated to be anemic. The effects of perinatal iron deficiency are anemia and most importantly neurodevelopmental impairments which are long-lasting and sometimes irreversible. The main goal of this study was to determine the influence of maternal and neonatal factors on the iron stores in neonates and to estimate the appropriate time to supplement iron for neonates in different scenarios.
Methods: This is a prospective observational study. Mother-infant pairs were enrolled in the study by following specific inclusion and exclusion criteria. Maternal demographic details, complications during pregnancy, intrapartum details, and neonatal details were recorded. The maternal and cord blood samples were collected for measurement of hemoglobin, serum ferritin, serum iron, total iron-binding capacity, and transferrin saturation. If failed to collect the cord blood sample, the first 24hour sample of the baby was taken into consideration in place of it. The correlation between maternal neonatal iron indices and the influence of the gestational age and IUGR on cord serum ferritin levels was analyzed by using paired t-test and chi-square test for multiple groups. A probability of p<0.05 (two-sided) was used to consider the difference as significant.
Results: 125 term and 47 preterm neonates were included in the study. There was correlation between maternal and neonatal iron profiles at birth when there was severe depletion of maternal ferritin (<12µg/dl) with p values less than 0.05 for hemoglobin and serum ferritn levels. Serum ferritin levels at birth were less in preterm as compared to term neonates (mean of 128.9µg/l in the preterm vs. 156.9µg/l in the term, p=0.04). There was a significant correlation between neonatal iron indices at birth with that at 28 days of life (p<0.01).
Conclusions: Neonatal iron stores are not affected unless there was severe depletion of maternal iron stores. Preterm neonates have low iron stores compared to term neonates. Gestational age is the major determinant for iron stores at birth as compared to other maternal and neonatal factors. As the most significant adverse effects of iron deficiency are irreversible and long-lasting neurodevelopmental impairments. The term and preterm babies should take prophylactic iron from eight weeks and four weeks of age respectively and continued up to the introduction of iron-fortified cereals as recommended by the American academy of paediatrics.

Published: January 2023

Background: Severe acute malnutrition is a major cause of mortality in children under 5 years of age in developing countries. Dehydration and Shock are the common serious complications of SAM and require cautious treatment. We carried out this study to compare 2 different guidelines given by WHO and IAP in patient of SAM with shock to compare their outcome and complications.
Methods: A randomized controlled trial was conducted during January 2019 to October 2019 at tertiary care centre of central Gujarat. Total 40 patients were enrolled according to inclusion criteria and randomized into two groups equally, Group A (following WHO guidelines) and Group B (following IAP guidelines). Rehydration therapy was given accordingly and patients were assessed for improvement in shock, developing complications and outcome as discharge or death.
Results: Out of 20 patients in each group, after bolus, not a single patient in group A showed improvement after 1 hour while in Group B 3/20 (15%) patients were improved. In Group A 8/20 (40%) and in Group B 12/20 (60%) patients showed improvement within 12 hours of bolus. In Group A 7/20 (35%) patients and in Group B 6/20 (30%) patients developed complication of fluid overload. In Group A 12/20 (60%) while in Group B 8/20 (40%) patients expired during the treatment.
Conclusions: Rehydration therapy according to IAP guidelines showed better improvement in shock, less incidence of complications and better outcome as compared to WHO Guidelines in SAM patients, however no significant difference was achieved due to smaller sample size.

Published: January 2023

Background: Neonatal pneumonia accounts for significant morbidity and mortality, especially in developing countries. Throughout childhood, the greatest risk of death from pneumonia is in the neonatal period. This study is done to study the risk factors and clinical characteristics of neonatal pneumonia. Aim of the study was to study the risk factors and clinical characteristics of neonatal pneumonia.
Methods: This was a hospital-based observational study conducted in the department of paediatrics, Gandhi medical college and hospital, Hyderabad. A detailed antenatal and postnatal risk factors were taken, and the clinical signs and symptoms of neonatal pneumonia were noted.
Results: Of the 100 neonates 30% of cases had early onset pneumonia and 70% had late onset pneumonia.50% of early onset pneumonia cases had antenatal risk factors.  There is a statistically significant association of age of onset of pneumonia with gestational age (p=0.002) late onset pneumonia being more common >37 weeks of gestational age. 80% of early onset pneumonia cases were associated with septicaemia.
Conclusions: Pneumonia is one of the most common causes of respiratory distress in neonates. Late onset pneumonia was more common. Major predisposing factors for early onset pneumonia are antenatal risk factors like premature rupture of membranes, maternal fever, major predisposing factors for late onset pneumonia are pre-lacteals, oil instillation in the nose, and aspiration of milk. Cough as a symptom was observed in late onset pneumonia.
