Les certificats d’économies d’énergie : nature hybride d’un outil de l’État piloté par les acteurs économiques
Authors: Rainaud Anne
Published: April 2021

Les certificats d'économies d'énergie s''inscrivent dans la logique du développement durable en contraignant les fournisseurs d''énergie à offrir sur le marché des produits qui permettent à leurs clients de réaliser des économies. Des obligations juridiques sont fixées au niveau national aux différentes catégories d'acteurs économiques concernés, et le jeu de l'offre et de la demande sert d'instrumentum pour parvenir aux ambitions étatiques. Les certificats ont donc une nature hybride, en laissant le consommateur avoir une capacité de participer à la réduction globale des énergies utilisées et en obligeant les fournisseurs d''énergie à des résultats de vente qui doivent correspondre au nombre de certificats d''économies à détenir. Créés en 2005, les certificats se pérennisent et se perfectionnent avec la loi sur la transition énergétique pour la croissance verte, notamment dans leur dimension sociale au profit des ménages en situation de précarité énergétique.

Authors: Rahman Md. Bazlur , Karim Tania , Chowdhury Imtiaz Uddin
Published: April 2021

Cybercrime becomes costlier than physical crime in developed economies. As a result, it has become the top priority in governance issues in financial institutions. As a developing nation in Bangladesh, the banking sector faces multi-dimensional challenges to adopt IT applications in banking with cybercrime. The paper examines what the banking industry faces cyber security risks and how the board members contribute to identify and mitigate the risk. Through an in-depth interview among the directors of commercial banks in Bangladesh, we identified the possible cyber risk and prepared the risk profile describing the sources, implications, severity of impact, likelihood of occurrence and ranked them. The result shows that the IT governance risk, IT investment risk, and information risk are most critical among the significant cyber security risks. The results of the study have important implications for both corporate boards and policymakers.

Published: April 2021

Obesity has been considered a complex and multifactorial disease that has almost affected one-third of the total world’s population. The present trend related to obesity has revealed that nearly 38% of the adults of the world’s population will suffer from the issues of being overweight by the year 2030. As per the ICMR-India study in the year 2015, the prevalence rate of obesity in India varies between 11.8% to 31.3%. The risk of cardiovascular diseases is prevalent around the world, and estimated CVD cases in the year 2015 were approximately 422.7 million, causing 17.6 million deaths (32%of global deaths) as per WHO statistics in 2016. The Indian health data of 2017 has revealed that 25.27% of the population have suffered mortality rate due to the occurrence of CVD in India. Hence, the implementation of health programs for identifying the community risk factors for preventing these diseases has evolved.

Gender and Behaviour Differences Influencing on Web Shopping
Authors: Ashok P
Published: April 2021

Despite several pieces of evidence showing the growth of Internet usage by Indian consumers. Online sales show less than 1 percent of the total retail sales in India. This may represent a great potential to grow yet some obstacles to overcome for online retailers. Many Indian consumers have low self-efficacy in using the Internet and feel shopping online to be eccentric. It seems that even for those who use the Internet regularly, the Internet is mainly for searching product information, comparing prices, and checking consumer reviews rather than making a purchase. Thus, the purpose of this study is to identify factors affecting Indian consumers’ attitudes towards shopping online. This information will help Internet retailers find a way to encourage Indian shopper’s online purchase behavior. Previous studies (i.e., Bhatnagar et al., 2000; Jarvenpaa and Todd, 1997; Vijayasarathy and Jones, 2000) attempted to identify factors affecting Indian online consumers’ online purchases. However, only risk and benefit factors identified from the US studies were applied to the Indian web shopping context, failing to incorporate Indian culturespecific factors. Thus, the purpose of this study is to identify factors affecting Indian consumers’ web shopping gender behavior, specifically elucidating them in the Indian context. In addition to the previously identified factors (i.e., Convenient and time-saving, on-time delivery, availability of detailed information about the product, safe and secure while shopping online, selection of goods available on the internet is a very broad, special offer/discounted prices, convenient and time-saving, shop online from a trustworthy website, easy price comparison to online and offline stores. Web shopping only if online prices are lower than actual price etc.); this study included Indian gender-specific factors that may play an important role in determining Internet adoption for e-commerce. Also, a potential gender difference in identifying factors affecting male/female purchase behavior was investigated.
Changing Objectives of Firms and Managerial Preferences: A Review of Models in Microeconomics
Authors: Pradeep Kumar B
Published: April 2021

Theoretically, producer behavior models postulate that firms have had different objectives ranging from profit maximization to setting aspirational levels. The assumption of the objective of profit maximization was shaped based on the rationality principles, which has lost relevance with the coming of the principle of behavioral economics in recent time. The present paper intends to throw some light on changes that have been made in the objective of firms over years and attempts to review some models emphasizing managerial utility as the core objective of firms.

An Analysis of Agriculture Sector of Inclusive Growth in India
Authors: Chennakrishnan P , Thenmozhi D
Published: April 2021

Agriculture remains the dominant supporter of the Indian populace. The thriving industry and service sectors depend on the agricultural sector for their development. The inter-linkage among the three sectors could not be undermined at any cost. It is the massive absorbent of the labor force even though the disguised unemployment exists in varied magnitude. The share of agriculture to the GDP has come down from 57.7% in 1950-51 to 32.2% in 1990-91 at the time of liberalization, 24.6% in 2000-2001, 15.7% in 2009-2010 then 17%. In the post-independence era, stagnant production, low productivity, traditional technology, and poor rural infrastructure were the major challenges for the Government. India is principally an agricultural country. The agriculture sector estimates 18.0% of the GDP and employs 52% of the total workforce. There is a continuous steady decay in its presence towards the GDP, and the agriculture sector is losing its shine and anchor position in the Indian economy. The problems with which the Indian agricultural scenario is charged in present times are many. Still, this in no way undermines the interest of the sector and the role it can play in the holistic and inclusive growth of the country. Agriculture is fundamental for the sustenance of an economy, as is food for a human being.
Método aproximado para determinar la potencia óptica en una linterna fotónica

Published: April 2021

Astronomy has benefited significantly from the development of photonic technology. However, the use of single-mode optical fibers in this area is not entirely efficient, this is mainly since its core, of the order of 8 microns in diameter, does not allow the capture of large amounts of light. In addition, in certain astronomical studies, it is required to analyze the multimodal incoherent light coming from the stars, particularly in the spectral range of the near infrared. One solution to these demands is the use of photonic lanterns, which are devices that function as an interface between a set of single-mode fibers and a multimode fiber, and in whose transition very low optical losses are obtained. However, there is not as far as we know, a mathematical method for the analysis of the behavior of the output power in photonic lanterns. Therefore, in this work we propose a numerical approximation method to determine the optical output power of single mode optical fibers in a photonic lantern, using the solution of eigenvalue equations, as well as the spatial capture of a part of the distribution of optical power, through of the end of a monomode tapered optical fiber.

Published: April 2021

A channel-type Fresnel surface was designed using the polynomial interpolation adjustment method. The experimental arrangement was composed of a metal complex, a high power LED lighting source, a cooling system and a Fresnel concentrator. The tests were done in a dark chamber, placing the compound at an effective focal distance from the reflected rays of the concentrator, for a time. By exposing the sample to the LED irradiation, its changes were registered in a UV-Vis spectrophotometer, obtaining an absorbance graph vs wavelength, the changes observed in the transition bands in displacement and intensity of the blue region to the red of the spectrum, confirmed the efficiency and usefulness of the Fresnel-type concentrator in the development of the photochemical reactor. This photochemical reactor has an advantage over commercial reactors, because it uses samples of compounds in small solutions, is portable, it can be implemented in university and pharmaceutical laboratories. The results were favorable, a low energy consumption was obtained, and a reduction of time in the molecular reaction process of the analyzed compound.

Published: April 2021

It is very important to carry out vaccination campaigns in the marginalized areas of our country, because they are more vulnerable to contracting diseases, but to do the appropriate containers are needed so that they arrive with their properties and to protect each person. The Seasonal Influenza vaccine is transported in portable refrigerators at a temperature of 2 and 8 ° C, and the storage time is within 3 and 7 days for the first and 12 to 36 hours for the second. This paper presents the modeling and simulation by Computational Fluid Dynamics (CFD) of a refrigerated system, from thermoelectric cells, for the storage of influenza vaccines. The results show the temperature distribution within the refrigerated system and the transfer of heat in each container element, as well as the most appropriate arrangement to keep each vaccine to the optimal storage temperature. Being able to count on portable systems that allow the optimal transfer of vaccines keeping refrigerated in a constant way would have a positive impact on the health of people who live in marginalized areas.

Published: April 2021

One of the limitations in agricultural production in the State of Guerrero is the various events of meteorological disasters, with the case of recurrent drought, hurricane winds, high rainfall that cause floods and very high daytime temperatures that directly affect annual crops (corn, beans and sorghum) and perennials (mango, lemon, avocados). In the entity there is little accurate and timely agroclimatic information that serves as a determining factor in the decision-making process of production processes. The present study has the purpose of developing a prototype of low-cost agrometeorological station. The data can be monitored via the Internet 24 hours a day, from the climate variables, such as: environmental temperature, relative humidity, rainfall, solar and ultraviolet radiation, wind speed and direction. With the storage of these climatological data, information will be obtained that contributes to the prevention of diseases and pests in the cultivation of corn, fruit trees and vegetables of economic importance. Reason for which the National Institute of Forestry, Agriculture and Livestock Research and the Technological University of the North Region of Guerrero, are joining forces in the development of a prototype of agrometeorological station.

İzmit Gulf is located between Kocaeli and Armutlu peninsulas at east of Marmara Sea and the interaction area of North Anatolian Fault Zone (NAFZ) and Marmara Graben systems. In this study, the faunal and floral contents (ostracod, foraminifer, mollusc and diatom) of the samples belonging to seven drilling cores were studied and obtained the radiocarbon and optically stimulated luminescence (OSL) age data in order to establish on the Black Sea – Marmara Sea - Mediterranean water connections and palaeoenvironmental changes. The sediments in this study are Late Pleistocene-Holocene aged and only cover the Marine Isotope Stages MIS-5 (interglacial), MIS-3 (an interstadial period between MIS-4 and MIS-2 glacial epochs) and MIS-1. The determination of ostracod and mollusc fauna of the Mediterranean and Ponto-Caspian origin provide important clues to water exchange between the Mediterranean and the Black Sea. Although some Mediterranean originated ostracods occur sporadically with low abundance, absence of foraminiferal fauna and existence of Ponto-Caspian ostracods together with fresh water and cosmopolitan diatom flora indicate that the area strongly interacted with the Black Sea waters during MIS-5. The faunal and floral characteristics of the sediments deposited during MIS-3, clearly denote that the Izmit Gulf was connected with the Black Sea and the Mediterranean Sea at the beginning of MIS-3 (ca. 52.0 - 40.0 ky BP) and the shallow shelf areas were frequently affected by both the Black Sea discharge and Mediterranean input. A thick Holocene sedimentary sequence recovered from the southern Hersek Burnu drilling cores reflects the environmental changes after the latest Black-Mediterranean seas connection. The studied ostracod and mollusc assemblages are mainly characterized by the Mediterranean originated species with a few relict Ponto-Caspian fauna. Also, the benthic foraminiferal assemblages are dominated by normal marine and euryhaline species, reflecting the salinity fluctuations in the Holocene interval.
Regulación de la virulencia en Bordetella bronchiseptica por BvgR, una proteína EAL atípica
Authors:   , Gutierrez María de la Paz
Published: April 2021

En esta Tesis doctoral se estudiaron los genes que la proteína BvgR regula en B. bronchiseptica así como los fenotipos en los que estas proteínas están involucrados. Los ensayos se realizaron con una cepa de B. bronchiseptica deficiente en bvgR. Mediante un análisis global de los genes expresados, utilizando la metodología de secuenciamiento de ARNm, se detectaron una gran cantidad de genes reprimidos y activados diferencialmente en el mutante ∆bvgR. Esta cepa además presenta una mayor movilidad en la fase virulenta de la bacteria, así como una mayor capacidad de formar biofilm respecto a la cepa silvestre. Por el contrario, la mutante ∆bvgR resulta menos citotóxica contra macrófagos que la cepa silvestre en ensayos in vitro y, además, en un modelo de infección en ratones induce una menor respuesta inmune y persiste menos en el tracto respiratorio bajo tras 21 días de infección. Por lo tanto, BvgR regula en B. bronchiseptica tanto factores de virulencia como de avirulencia y está implicado en la regulación de distintos fenotipos requeridos para la patogénesis de la bacteria.

ASSESSMENT OF DENTAL CARIES IN INDIVIDUALS WITH INTELLECTUAL DEVELOPMENTAL DISORDER IN KOZHIKODE DISTRICT– A CROSS-SECTIONAL STUDY
Authors: Mukundan Nimmy S , Balan Prasanth , S Jayasree
Published: April 2021

Background: Individuals with intellectual developmental disorder (IDD) suffers from poor oral health
due to impaired physical coordination and cognitive skills. However, their dental caries status is mostly
underreported particularly in low-income countries. Therefore, this study aimed to assess the dental caries status of individuals
with IDD as compared to age and gender matched healthy individuals in India.
Methodology: In this comparative cross-sectional study, dental caries status of 266 individuals with IDDs aged 13-35 years and
266 age and gender-matched healthy individuals were assessed using the DMFT index. Statistical analysis was done using
descriptive statistics, Wilcoxon signed ranks test, Kruskal Wallis Test and Mann Whitney test.
Results: Of the 266 individuals with IDD, IDD associated with autism (n=40, 15%) was the most common type of disability.
10.9% of the case and 30.5% of controls were caries-free. The mean number of decayed tooth and the DMFT score (DT=
4.16±4.17 vs 0.65±0.90; DMFT= 4.56±4.55 vs 1.41±1.42); P Value=0.00) were signicantly higher among disabled compared
to their healthy controls. Whereas the mean number of the lled tooth (0.18±0.81 vs 0.68±1.1; Pvalue=0.00) was signicantly
lower. DT and DMFT increased signicantly with the severity of disability (P value<0.05).
Conclusion:Individuals with IDD had a highercaries experience and considerably lower lled tooth ratecompared to healthy
individuals. Uplifting the priority given to oral health by oral health education programs and implementing strategies to
improve access to dental services will help to address many of the challenges faced by these lessfortunate individuals.

Power and sovereignty
Authors: Emblad Patrik
Published: April 2021

How do nation states relate to each other in terms of power? How do they relate to private parties in terms of power? Nation states are often thought of as sovereign to tax. In a legal sense that may be true. However, to be legally sovereign is not the same thing as being able to effectively exercise sovereignty. The mobility of capital and businesses, or at least the perception of their mobility, is increasingly pressuring sovereignty to tax. To shed light on the economic constrains on nation states and the beliefs about such constrains, this article introduces the concept of economic-ideological forces and contends that sovereignty should be understood in a way that encompasses these forces. Otherwise, it does not provide an adequate account of power and thus becomes a tool for maintaining established power relations.

Published: April 2021

To assess the effect of the mould filling modes on the content of oxide films in castings, special criterion is proposed that provides prediction in the contamination of chill castings mаde of aluminum alloys by using modern computing tools to simulate the moulds casting process on computer. It is noted that decrease in the value of the contamination criterion by using alloys with low content of Mg or without this component reduces the possibility of controlling the distribution of oxides in the casting, other elements of the casting mould and using the concentration of oxides, for example, in washers to control the mechanical properties of cast products. This is due to increase in the duration of oxidation processes in gas-tight mould with such change in the composition of the casting material.

В работе исследованы психофизиологические показатели студенток в зависимости от курса обучения. Исследование проведено с помощью методики теппинг-теста, которая позволяет оценить скорость работы и работоспособность испытуемых, а также установить силу нервных процессов у обследуемых. Указанные параметры исследованы у студенток первого, второго и четвертого года обучения в вузе.
Выявлено, что работоспособность в процессе выполнения теста быстрее падает у студентов первого курса, хотя при этом они демонстрируют высокую скорость работы. Самые высокие скорости работы были отмечены у студенток второго курса, а самые низкие – у студенток четвертого курса. Таким образом, к четвертому курсу падают скоростные характеристики. Функциональная асимметрия при работе правой и левой руками была лучше выражена у студенток первого курса. К четвертому курсу она выражена хуже. Возможно, изменения указанных психофизиологических параметров вызваны ослаблением функциональных резервов испытуемых в результате учебных нагрузок и гиподинамии. По результатам теппинг-теста у студенток была установлена средняя сила нервных процессов.

Статья посвящена изучению картины крови мужчин с разным сроком курения табака. Результаты проведенных исследований показывают, что курение табака не приводит к существенным изменениям показателей картины крови.
Концентрация эритроцитов в крови мужчин со стажем курения подвергается незначительному увеличению с достижением максимального значения – 5,4 млн в мкл крови по группе до 15 лет, а затем имеет тенденцию к снижению. Количество гемоглобина, постепенно увеличиваясь, доходит до 156,0 г/л по группе до 20 лет, свыше двадцати падает до 154,0 г/л, а в контроле составляет 144,0 г/л.
Курение табака до 20 лет способствовало росту количества лейкоцитов у мужчин. С увеличением стажа курения происходит постепенное и незначительное падение уровня нейтрофилов, достигая минимума – 53,2% по группе до 20 лет, а у некурящих мужчин – 61,4%.
Содержание эозинофилов и базофилов в крови у курильщиков с разным сроком курения табака сохраняется на одном уровне.
Концентрация лимфоцитов, моноцитов и тромбоцитов в крови курильщиков с увеличением стажа курения табака подвергается незначительному увеличению.

Нарушение баланса микроэлементов считается одной из часто диагностируемых проблем. Однако иногда дефицит микроэлементов может протекать без каких-либо клинических проявлений. В этом свете клинический интерес к определению микроэлементов для диагностики различных заболеваний в последние годы возрос. Метаболизм микроэлементов может быть связан с поступлением их и доступностью в пище, распределением, абсорбцией, экскрецией, мобилизацией, хранением и биохимической активностью.
В целях оптимизации микроэлементного обмена животных в биогеохимическом регионе нами изучено влияние комплексонатов, приготовленных на основе этилендиаминдиянтарной кислоты, на гемопоэтические показатели животных.
Результаты показали положительное влияние микродобавок на гемопоэтические показатели козлят.

Published: April 2021

Este artigo busca explorar, a partir de uma experiência prática envolvendo conteúdos de matemática financeira, o uso da Resolução de Problemas enquanto metodologia para o Ensino de Matemática. Para isso, desenvolvemos uma pesquisa de campo a partir de um projeto de intervenção pedagógica executado em uma turma de primeiro ano do Ensino Médio de um colégio estadual do município de Aiquara-BA. As atividades que constituíram o núcleo do projeto de intervenção foram elaboradas à luz das pesquisas de Polya (1995) e Onuchic (1999), os quais serviram de referencial teórico-metodológicos. O tema selecionado para as atividades envolveu os conceitos de porcentagem e de juros. A partir da análise dos problemas trabalhados pelos estudantes e das observações do professor regente durante as atividades, um conjunto de dados foi organizado. Avaliando-os, foi possível identificar que a utilização da Resolução de Problemas como metodologia de ensino contribuiu para o desenvolvimento de diferentes aspectos do processo de ensino-aprendizagem, como o raciocínio lógico, a capacidade argumentativa e o trabalho em equipe. Além disso, constatamos uma mobilização mais efetiva dos conhecimentos prévios dos estudantes e de suas percepções a respeito dos potenciais de utilização dos conteúdos trabalhados em situações cotidianas práticas. Esperamos com isso poder contribuir para uma melhor compreensão dos potenciais envolvidos no ensino de matemática através da Resolução de Problemas.
Memes, Matemática e formação com professores/professoras : uma perspectiva sociopolítica
Authors: Friske Andréia , Rosa Maurício
Published: April 2021

Este artigo tem o objetivo de investigar como se mostra a forma/ação com professores/professoras que ensinam matemática, em termos da dimensão matemática da Cyberformação, quando desenvolvem atividades-matemáticas-com-memes. Compreendemos a Cyberformação como uma forma/ação que considera as Tecnologias Digitais como partícipes do processo de constituição do conhecimento matemático. Assim, para obter dados para essa pesquisa foi planejado e desenvolvido um curso de extensão denominado “A fim de memetizar? Construindo atividades-matemáticas-com-memes”. O público alvo foram professores e professoras que ensinam matemática na região metropolitana de Porto Alegre, do estado do Rio Grande do Sul. Como resultado de pesquisa, nesse artigo, evidenciamos um discurso democrático de participantes no desenvolvimento de atividades-matemáticas-com-memes e diferentes interpretações da relação entre Educação Matemática e democracia. Dessa maneira, assumimos que a constituição do conhecimento matemático de professores/professoras se mostrou como sociopolítico e democrático, evidenciando uma matemática que busca pontes entre teoria e prática, dialeticamente em práxis.

Published: April 2021

Background: Central induction policy is recently implemented for induction of doctors for post-graduation training based on their performance in MBBS, post-graduation entrance exam, house job, studying in public institute, work in periphery and research. Despite controversies this policy was implemented in May 2016 and no feedback was taken by the stakeholders. This discrepancy aroused the need for data collection to determine effectiveness of CIP in terms of PG perceptions.

Subjects and methods: An interview based qualitative study was conducted in four Tertiary care hospitals from 05 June 2018 to 30 November 2018. Request forms were randomly sent to 75 residents inducted through and before CIP. Total 39 residents participated in the study after giving consent. Interview questions were selected by the authors after detailed discussion. Each interview was heard thrice, manuscripts were prepared in the same words used by the participant. Manuscripts were discussed among the team members to identify themes. Depending upon themes questionnaire was designed and quantitative data was collected.

Results: Qualitative evaluation identified following major themes including policy being merit based allowing every candidate to get a fair chance of induction; financial security on all the slots and provision of qualified doctors at primary health care centers for the induction policy whereas issues with choice of specialty and place of work, delay in start of training due to various factors and discrepancy in special cases like wedlock, FMGs, authenticity of research papers were identified as demerits.

Conclusion: CIP is a good initiative and is acceptable due to its merit based policy and financial security however there is need to improve the standard and evaluation method of research and option for change of specialty.

Published: April 2021

Background: Many studies have been conducted worldwide to evaluate the proportion of patients with Celiac disease (CD) in persons presenting with Irritable Bowel Syndrome (IBS), showing a positive association between the two diseases. However, reports from Pakistan remain scanty. This study aims to find out the prevalence of CD in patients presenting with IBS and to establish the correlation of both diseases.

Patients and methods: It was a descriptive cross-sectional study conducted at Combined Military Hospital, Lahore (CMHL) from January 2018 till March 2019. Consecutive, nonprobability sampling was used to include 210 patients of both genders with the age range of 15-65 years fulfilling ROME IV criteria and were not previously diagnosed as CD or CKD or CLD. Demographic data was noted. Serum Anti tTG levels and Duodenal Biopsy from the second part was assessed to diagnose CD. CD was labeled if the disease was present on both serological and Histopathological reports. Data were analyzed by using SPSS version 20. Descriptive statistics were calculated and a Chi-square test was used to compare the outcome variables with P-value < 0.05 as significant.

Results: Of 210 enrolled patients, 113 (53, 8%) were male and 97 (46.2%) were female. The mean age of the patients was 28.40 ± 5.06 years. Eight patients (3.8%) were positive for Anti tTg and on histopathological findings suggestive of CD. Seven of 8 were less than 35 years old. Out of 8 positive patients, 6 (75%) were females. However, the p-value was found to be insignificant for age (0.549) and gender (0.096). On stratification with respect to duration of IBS, all 8 patients diagnosed with celiac disease were having symptoms of IBS for less than 12 months (100%) which was significant statistically (7.1% vs 0.0%; p=0.007).

Conclusion: The frequency of CD was 3.8% among IBS patients. Considering this percentage of CD in IBS patients s, a high index of suspicion for CD in IBS patients is required,

Background: Pakistan is a resource limited country with one of the highest neonatal mortality rate (NMR) in the world. Kangaroo Mother Care (KMC) helps in reducing the mortality and improving the care of preterm babies. The objective of this study was to identify the benefits of KMC in hospitalized newborns in terms of better weight gain and early discharge from hospital.

Subjects and methods: A retrospective case-control study was conducted in the Neonatal Department of Services Hospital from 01.02.2019 to 31.01.2020. A total of 144 case notes, who met inclusion criteria were included. Subjects were divided in 2 Groups of 77 each. Group 1 did not receive KMC and Group 2 received KMC (partial or complete). Admission weight, gestational age at birth, duration of hospital stay and the average weight gain was noted for subjects in both groups. SPSS version 23 was used to analyze data. Independent samples t-test was applied. A p-value of ˂0.05 is taken as significant.

Results: Mean weight gain in Group 1 was 5.521 g/kg/day (±6.664), whereas in Group 2 was 15.635 g/kg/day (±9.268). Mean hospital stay in Group 1 was 12.558 days (±10.856) and in Group 2 it was 8.208 days (±6.473). Weight gain and duration of hospital stay was significantly better in KMC Group with a p-value ˂0.05. This benefit was observed both for partial and complete KMC.

Conclusion: KMC (partial or complete) leads to better weight gain and reduces the duration of hospital stay.
