AS RELAÇÕES DE PODER NO SEMIÁRIDO NORDESTINO
Authors: Santos Alane Regina Rodrigues dos , Santos Carina Angélica dos , Santos Andréia Rodrigues dos
Published: March 2017

O semiárido brasileiro está compreendido em uma área de 982.566,3 km2 e abrange o norte do Estado de Minas Gerais, os sertões da Bahia, Sergipe, Alagoas, Pernambuco, Paraíba, Rio Grande do Norte, Ceará e Piauí, o que corresponde a 18,2 % do território nacional e abrange 1.133 municípios. O sertão é uma região caracterizada pela irregularidade de chuvas e pela semiaridez do seu clima que periodicamente assola a população. Devido essas particularidades, por muitos anos, o Nordeste enfrentou de forma extremamente hierarquizada, um processo civilizatório e colonizador no qual o deixou a mercê do clientelismo e dos grandes latifundiários. Diante desse contexto, o apadrinhamento e a forma patrimonialista marcaram o território nordestino, mais especificamente o semiárido, que por vários anos foi liderado pelos coronéis da região que concentravam todo o poder em suas mãos. Assim exposto, o presente artigo tem como objetivo geral discutir as relações de poder que ao longo dos anos vêm contribuindo com o quadro de dependência, extrema pobreza e aumento agudo da espoliação social da população do semiárido. São objetivos específicos, descrever como se deu a interferência do Estado em relação aos problemas relacionados com a problemática da seca, bem como identificar de que maneira vem ocorrendo a substituição patriarcal dos coronéis pelo assistencialismo governamental. Em princípio pretendeu-se descrever as características do semiárido nordestino e da seca que ocorre frequentemente na região. Em contrapartida, apresentam-se as relações de poder das classes dominantes que se beneficiaram, indevidamente, com os investimentos e subsídios oferecidos pelo governo. Em acréscimo, apresenta-se um breve recorte sobre os programas e políticas públicas voltadas para a convivência com o semiárido. É importante ressaltar, que os procedimentos metodológicos utilizados nesta pesquisa foram documental e bibliográfica em dissertações, teses, artigos, livros e periódicos relacionados com o tema.  Nesta perspectiva, o presente estudo foi baseado pacificamente em autores conceituados, tais como: Weber (1999), Arendt (1985), Poulantzas (1985), Duarte (2001), Silva (2006) entre outros.
A CONSTRUÇÃO ESCOLAR DA HIPERATIVIDADE: CONTROVÉRSIAS ACERCA DO TRABALHO DE DIAGNÓSTICO E INTERVENÇÃO EM TORNO DE JOVENS COM PHDA EM ESCOLAS PORTUGUESAS
Authors: Feijão João Monteiro , Freitas Nélia Martins
Published: March 2017

Este artigo resulta de um trabalho de pesquisa em torno do tratamento e do diagnóstico da Perturbação de Hiperatividade e Défice de Atenção (PHDA) em jovens nas escolas portuguesas. Mais concretamente, procurámos compreender a construção escolar que é feita pelos profissionais de ensino e pelos técnicos educativos sobre estes alunos, como é realizado o trabalho de diagnóstico e intervenção quotidiana sobre os mesmos, bem como identificar os acordos e desacordos existentes entre os professores e os técnicos quando estes justificam e defendem o seu ponto de vista sobre a melhor forma de intervir sobre cada caso. A abordagem teórica privilegiada é a sociologia pragmática de Luc Boltanski e Laurent Thévenot, que nos permite perceber como os atores sociais experienciam as situações em que estão envolvidos, concebendo-os como competentes e capazes de emitir pontos de vista críticos para ajuizar situações e expressar os seus sentimentos de (in)justiça. Os principais resultados, obtidos nesta pesquisa, refletem um aumento dos diagnósticos desta patologia, existindo contudo algumas dúvidas na qualidade e fiabilidade dos mesmos. Foi possível concluir igualmente que a perceção dos professores se altera quando o aluno é diagnosticado, praticando-se uma inclusão escolar depois da exclusão e da construção de uma identidade deteriorada no contexto da sala de aula. Relativamente às formas de tratamento desta patologia no contexto escolar registaram-se algumas críticas ferozes à comunidade cientifica pela inexistência de consensos e definição do que é um aluno hiperativo e/ou com défice de atenção. Em relação à sua relevância social e científica, este estudo permite uma compreensão mais alargada da realidade em que estes jovens vivem no contexto escolar, sendo útil tanto para professores, como para técnicos educativos, familiares com filhos com o mesmo problema e para investigadores que se dediquem à problemática da regulação de comportamentos e da reparação de alunos com identidades deterioradas nas escolas.
ENTRE NAÇÕES E LEGISLAÇÕES: ALGUMAS PRÁTICAS DE “LEGALIDADE” E “ILEGALIDADE” NA TRÍPLICE FRONTEIRA AMAZÔNICA (BRASIL, COLÔMBIA, PERU)
Authors: Albuquerque José Lindomar , Paiva Luiz Fábio Silva
Published: March 2017

O trabalho analisa as formas sociais de construção das legalidades e das ilegalidades na tríplice fronteira entre Brasil, Colômbia e Peru, onde as relações entre nações são mediadas por leis e normas sociais diferenciadas e não correspondentes. Observa-se como se estruturam fluxos e circuitos de pessoas e mercadorias por diferentes legislações nacionais. Esses circuitos são produzidos e produzem o diferencial fronteiriço, isto é, as assimetrias dos preços, serviços e sistemas de controle social de cada um dos três países. As legislações nacionais heterogêneas e as formas de fiscalização, mais rígidas ou flexíveis, mobilizam os deslocamentos entre territórios nacionais. Entre Tabatinga (BRA), Letícia (COL) e Santa Rosa (PER), as fronteiras entre o “legal” e “ilegal” mobilizam muitas redes e fluxos em torno, por exemplo, da legalidade das brigas de galo no Peru e Colômbia e a “ilegalidade” e “clandestinidade” dessas práticas em território brasileiro.

A review of case histories of induced seismicity caused by hydrocarbon production and storage
Authors: Vadillo Fernández Lucas , Fernández Naranjo Francisco Javier , Rodríguez Gómez Virginia , López Gutiérrez Julio
Published: March 2017

In this article we review the stress-strain relationships that take place in the crust during some of the main hydrocarbon production and storage processes: gas extraction; water injection in wells to stimulate the extraction of oil (EOR); unconventional hydrocarbon production by hydraulic fracturing (fracking); disposal of wastewater (saline water) from the extraction of conventional and unconventional hydrocarbons such as saline water return (flowback) of hydraulic fracturing, both with TDS higher than 40 000 mg/L. In addition, the type of faults that are more likely to slip and the induced seismicity related to the production and extraction of hydrocarbons are analysed.
Отражение сочетания генотипов по полиморфным локусам COMT Val158Met и MAOA -uVNTR в психологических особенностях девушек

Published: March 2017

In recent years, much research on psychological features of carriers of different genes has been done. Studying the role of combinations of various genes in the formation of personal traits is the next step in the understanding of the specificity of the influence of genes on personality traits. The MAOA and COMT genes of the monoaminergic system are the subject of research of psychologists because of their impact on the duration of stay of neurotransmitters-monoamines in the synaptic space, and hence their potential impact on the duration and intensity of emotional reactions. Taking into account the constancy of this influence the authors assumed that these genes could be associated with stable personality characteristics, which was confirmed by not numerous scientific studies.The paper presents the results of the study, which involved 115 girls at the age from 18 to 30. The procedure of genotyping with the discrimination of polymorphic loci of MAOA -uVNTR and COMT Val158Met was the first stage of the experiment. The psychodiagnostic stage included the study of personality traits of the participants: the level of aggression, types of legitimized aggression, types of behavior in the conflict, formal and dynamic properties of individuality, and tendency to various forms of deviant behavior. The results of the study enabled to make psychological portraits of carriers of various combinations of genes. The carriers of the combination of the high-activity forms of the studied genes had the sanguine temperament, high aggression, intellectual speed, and flexibility. The carriers of the combination of the MAOA M heterozygous genotype and the low-activity genotype of AA COMT had the melancholic temperament, low level of aggression, intellectual speed, and flexibility. In the present study the authors made the assumption that the COMT A allele was associated with the tendency to suppression of aggression; the COMT G allele was probably associated with the preference for open forms of aggressive behavior and a high level of general activity. The COMT heterozygous genotype was associated with a low level of aggression; the MAOA L genotype was associated with a high level of aggression.

Studying the correlation between the characteristics of the structure of genes and the parameters of the evoked brain activity is a relevant problem of modern research. It is known that the MAOA gene, which influences the concentration of such neurotransmitters-monoamines as dopamine, serotonin, and norepinephrine, is associated with different psychological characteristics. However, very little is known about the association of this gene with psycho-physiological indices. The purpose of the present study was to investigate the characteristics of amplitude and spatial-temporal characteristics of the evoked brain activity in girls (at the age from 18 to 24) who were carriers of different MAOA genotypes. According to the results of genotyping, the participants (61 persons) were divided into two groups: with the high-activity and heterozygous MAOA -uVNTR genotypes. In the study the authorsrecorded visual evoked potentials in 64 derivations. Emotionally charged and neutral images were stimuli in the study.The paper describes modern views on the correlation between MAOA genotypes and the features of cortico-limbic interaction. The results of the study showed that the heterozygous genotypes were apparently associated with lesser efficiency of regulating functions. To activate neural systems of the frontal divisions the female carriers of the heterozygous genotypes of MAOA needed the stimuli with a high arousal effect; this can be connected with a less efficient process of selecting relevant stimuli. At the same time, the high-activity MAOA genotypes in women are probably associated with high efficiency of controlling functions (attention, planning, control) of the prefrontal cortex when assessing emotionally charged images, which is accompanied by the intensity of activation of these brain structures.

The article analyzes the factors contributing to the formation of different models of relations in primary parental families, which further can be preconditions for the child’s aggressive and hostile behavior towards other people. Parents’ basic socio-psychological needs (SPN), including the need for inclusion, control, and love, were considered as a factor of relationships in the family.The paper presents the results of the study of married couples and their preschool schildren, which showed that socio-psychological needs of mothers and fathers determined the parameters of interaction in the “mother – child / father – child” pairs, as well as relation of the mother/father to the family, the husband/wife, and the child’s relation to the mother/father. The study showed the following: (a) the prominent need for inclusion conditioned a higher intensity of a positive relation to their own families in men and women; (b) parents’ needs for control/dependency played a special role in the formation of the child’s relation to his/her mother and father; (c) the mother’s need for other people’s love conditioned the parameters of her interaction with her child; (d) compared with mothers, fathers’ socio-psychological needs conditioned the interaction with their children to a lesser degree.The comparative analysis between the level of socio-psychological needs in mothers and fathers and the parameters of their emotional interaction with their own children showed that mothers scored higher on the scale of the need for inclusion in various social groups, as well as in the parameters of emotional interaction with the child. The obtained results enabled authors to draw the conclusions about (a) the actualization of the mother’s need for inclusion in various social groups at this stage of life, (b) emotional involvement of mothers in the communication with their children. Mothers were more inclined to understand the emotional state of their children, showed empathy, experienced a greater variety of feelings in the communication with their children, as well as related to themselves as to a parent more positively.

Published: March 2017

The article deals with the problems of forming leadership competencies in institutes of higher education. Requirements of consumers of educational services – the state, universities, students, and employers – have confirmed the relevance of this issue. Being based on the analysis of the Federal State Educational Standard  of areas of economics (economics, management, personnel management, and etc.) the paper presents an original questionnaire for employers, teachers, and students. The questionnaire highlighted the main common cultural and professional competencies and revealed the most needed knowledge, skills, and abilities of young professionals. The paper provides an overview of domestic and foreign research of leadership in the student’s environment, as well as the results of the carried out study. The analysis of theoretical approaches to leadership enabled to generalize and concretize the concept of “leadership competence”. Thus, the article defined leadership competence as a leadership metacompetence which made it possible to cultivate leadership qualities, adapt to new conditions, and also facilitated the acquisition of other competencies. The study, which involved students, teachers, and employers of the Southern Federal District, distinguished the main components of “leadership” competence, highlighted the main leadership qualities in students, and assessed the leadership qualities in heads of student groups.

Research methods included a number of author’s questionnaires. Thus, the questionnaire consisting of 45 items (in the framework of the technique of “360 degrees”) was used for assessing the leadership qualities in the heads of student groups. A comprehensive approach of testing, enabling to cover the problem from different points of view and levels of hierarchy (students, teachers, curators, and heads) was the main purpose of this assessing. The results of the carried out study made it possible to specify the definition of “leadership” competence, highlight the main characteristics of leadership qualities in the student’s environment, and suggest directions of forming leadership skills in institutes of higher education.

This article touches upon the psychological status of the concept of “selfsacrificingness” and demonstrates its importance for the efficiency of the soldier. The features of the transformation of the ordinary semantics of “self-sacrificingness” are connected with the reduction of transcendental connotations and strengthening of humanistic ones. There is a lack of psychological reflection of the content of qualities of soldiers, which are required in service regulations and described in scientific studies as conditions of their willingness to implement the duty to defend the Fatherland. The authors (a) carried out the comparative analysis of the concepts of “self-sacrificingness” and “altruism”, (b) revealed the incompleteness of the concept of “altruism” to designate the readiness for a sacrificial act, (c) demonstrated the interrelation of self-sacrificingness with the level of sense development of the person, and (d) adduced the results of the empirical study of the sense development of conscripts and their willingness for sacrificial behavior. The study was carried out according to a multiparadigm logic, with the use of propositions of cultural-historical, existential, and psychosemiotic approaches. The study involved 45 conscripts. The authors developed a questionnaire for the diagnosis of the willingness for sacrificial behavior. To determine the level of sense development they used diagnostic indices of “object-centrism” and “sense 2”, techniques of psychosemiotic analysis of essays on any topic, as well as the index of decentration of the “Technique of Ultimate Senses”. The paper presents the analysis of the revealed correlations of the obtained scores of diagnostic indices. The results of the study demonstrated a direct correlation between self-sacrificingness and religion, everyday forms of helping behavior, as well as the level of sense development of the respondents; there was a reverse correlation with the index of self-esteem. The present study showed the importance of modeling and implementation of developing programs for conscripts, aimed at the development of the system of personal senses that can compensate for the sense insufficiency of the modern educational environment and contribute to their willingness to perform military duty.

This paper examines how young men and girls, who belong to the Islamic confession, experience mythological fears associated with the so-called “demonic possession”. The young people having a high level of mythological fears are at risk of the influence of non-traditional branches of Islam. The paper presents the empirical study of the correlation between the representations of demonic possession (“a jinn’s entering the body of a person”) in representatives of the Muslimconfession and their personal traits. For studying the representations of demonic possession the authors developed a special questionnaire consisting of 5 scales. The techniques for studying the respondents’ personal traits included the following: H. Eysenk’s techniquefor temperament assessing, Rotter’s locus of control scale, G. Shmishek’s questionnaire for assessing character accentuation, and J. Taylor’s anxiety questionnaire. The study involved 200 students of three universities of the Chechen Republic (100 young men and 100 girls).The empirical data of the study demonstrated the degree of the respondents’ religiosity, the level of their mythological fears, and the correlation with individual-psychological traits of the student’s personality. According to the research findings, the individual-psychological traits of personality influenced the level of mythological fears in adolescence. There was a correlation between the individual-psychological traits of personality and the degree of its susceptibility to the excessive mythologization of the religious content.The findings of the study of the youth sample showed psychological features of the perception of the phenomenon of “possession with a jinn”. The results of the study enabled to develop a comprehensive program of psychological and pedagogical support of students of higher educational institutions, secondary technical educational institutions, and specialized secondary schools. The program consistedof 4 modules and aimed at the educational and correctional work with students with a high level of mythological fears, as well as prevention of young people’s involvement in extremist and terrorist activities.

The paper brings forward the results of the scientific study of senior schoolchildren’s (at the stage of graduation from secondary school) representations of their career prospects. The study of features of senior schoolchildren’s career planning is the urgent problem of scientific studying. The authors (a) suggested understanding career prospects from the point of view of the system approach, (b) described the structure and designated the components of career prospects in senior schoolchildren. Being based on fundamental provisions of the system approach and the content of the “life prospects” definition, the authors distinguished principal structural components of career prospects: cognitive, affective, motivational, value, and behavioral.The paper presents a model of career prospects; the degree of the formation of components of this model was the main criterion for determining its development/presence. The analysis of the respondents’ representations of their career prospects enabled authors to distinguish four basic types of career prospects: fully formed,partially formed, insufficiently formed, and unformed ones.

The analysis of the results of the empirical study made it possible to quantitatively and qualitatively describe the features of the components of career prospects in senior schoolchildren at the stage of graduation from secondary school. The duration of senior schoolchildren’s individual planning of career prospects manifested itself in three stages: the stage of nearest career prospects (from three months to six months), stage of medium career prospects (from three to five years), and the stage of distant career prospects (from five to ten years).The results of the study showed the following principal factors of career prospects in the group of senior schoolchildren: “concrete life values”, “social activity to achieve status”, “altruism”, “need for  communication”.

The paper shows the relevance of studying problems of academic motivation in junior schoolchildren in the modern educational environment. The consideration of features of academic motives in elementary school depending on types of educational programs – “School 2100”, “School of Russia”, and “Harmony” – gained specialattention. The present study analyzed the structure of the motivational sphere of schoolchildren in the context of leading activities.Theoretical bases for the consideration of the aspects of this problem were (a) fundamental approaches to the study of motivation and personality and psychological theories of motivation (V. G. Aseev, D. A. Leont'ev, A. Maslow), (b) leading methodological and theoretical approaches to the study of academic motivation (L. I. Bozhovich, A. N. Leont'ev, L. M. Fridman). The present paper aimed to study features of the hierarchy and types of academic motives, caused by the specificity of the implemented educational program. To achieve this goal the authors organized and carried out an empirical study.

There were statistically significant differences in the levels and types of academic motivation in the junior schoolchildren trained in different educational programs. A high level of academic motivation, prevalence of cognitive and academic motives, motives of cooperation and self-development, and manifestation of the personal sense of learning in the structure of academic motivation were characteristic features of theschoolchildren trained in the “School of Russia” program. Social motives prevailed in the structure of academic motivation in the schoolchildren trained in the “School 2100” program. A high level of the development of goal-setting in learning activities and the predominance of motivation to achieve success in teaching dominated in the schoolchildren trained in the “Harmony” program. The findings of the study can be readily used in practice in activities of elementary school teachers and educational psychologists to improve the educational process in elementary school and raise academic motivation in schoolchildren.
Психологическое сопровождение профессионально-личностного развития педагогов: антропологический подход
Authors: Dem'yanchuk Roman V.
Published: March 2017

The paper overviews the original model of the psychological support of the personal and professional development of teachers, which is based on theoretical and methodological principles of the anthropological approach. The ideas about the necessity of shifting the focus in the understanding of the essence of development as a very individual process of self-actualization and selfrealization gradually replaces the traditional understanding of the personal and professional development of teachers, which is based on the system of demands of the profession and its linear stages. Applying the logic of the anthropological approach to the understanding of this process is based on the idea of transcending the self of the teacher as the subject of development from the actual self (initial-personal) to the desired self (professional and personal) through the conjugation of personaland professional psychological fields. The process character of professional and personal development involves the process character of psychological support. The structure of the suggested modelcontains the following main processes: basic and dynamic diagnostics, information, counseling, training and development, psychological support of the educational process (components of the psychological-pedagogical unit of the model). The auxiliary processes of the model are (a) creating and maintaining of a favorable socio-psychological climate in educational institutions, (b) creating and maintainingof favorable conditions for self-realization and self-actualization of teachers, (c) motivation, and (d) stimulation (the organizational-pedagogical unit of the model).The present article determines the main goals of the psychological support of professional and personal development and concludes the priority of the anthropological approach in the organization and content of support, as well as the relevance of finding ways of the improvement of psychological preparation of future teachers for further professional and personal development, which defines its vectorthrough the formation of the image of the standard personality of a professional.

Authors: Gonzales Chávez Salome
Published: March 2017

La demanda diaria del Sistema Eléctrico Interconectado Nacional-SEIN, posee características muy peculiares de tendencia, estacionalidad y aleatoriedad, situación que complica al proceso de estimación de su pronóstico. El objetivo del presente trabajo consiste en formular y calcular modelos ARIMA con Análisis de Sucesos Externos, a fin de lograr pronósticos eficientes de la demanda eléctrica de cada día siguiente, a nivel total y desagregado por áreas. Un buen pronóstico de la demanda diaria garantiza el despecho eficiente y económico de generación y transmisión, así como el aseguramiento y calidad de la demanda sectorial nacional. El enfoque metodológico lo constituye el tratamiento de cada serie temporal objetivo, mediante transformaciones estadístico-matemáticas apropiadas para alcanzar estabilidad tanto en varianzas como en medias regulares y estacionales; paralelamente filtrar los sucesos externos hasta alcanzar a un Modelo ARIMA predictivo de cada área del sistema eléctrico del Perú (Centro, Sur y Norte) y para cada día de la semana. Los resultados alcanzados en la presente investigación demuestran la eficiencia predictiva comparativa. Es decir, tomando como indicador de calidad de pronóstico al Error Absoluto Promedio Porcentual (MAPE), se han obtenido valores inferiores al 1% en las proyecciones de la demanda diaria total del SEIN, frente al 2% que se logra con actuales técnicas determinísticas.

ABSTRACTThe daily electric demand in Peruvian National Interconnected System-SEIN- has very particular trend, seasonality and characteristics external effects, a situation that complicates the process of estimating the short-term forecast. The aim of this paper is to formulate and calculate ARIMA models with External Events Analysis to achieve efficient forecasts of electricity demand each day, at total level and broken down by areas of the SEIN. The methodology is based on treating each time series using appropriate statistical-mathematical transformations to achieve stability in variance as regular seasonal averages, parallel external events to try to reach an optimal predictive model ARIMA each area of the electrical system of Peru (Central, South and North) and for each day of the week. The results demonstrate the predictive efficiency. Taking as a quality indicator forecast the Mean Absolute Percent Error (MAPE), have obtained values lower than 1% by the projections of the total daily demand SEIN versus 2% obtained with existing deterministic techniques.

RESUMENEn este trabajo exponemos un método para abastecer de energía eléctrica a un grupo de personas que habitan en el distrito de San Borja – Lima, a través de un Sistema Fotovoltaico (SFV), lo cual no es común en la zona. Esto ayudará a disminuir los niveles de emisión de dióxido de carbono (CO2) a la atmósfera. Se ha determinado mediante el Atlas Solar del Perú que la potencia solar en la región de la costa alcanza al día un promedio, en el mes de marzo, de 6 a 6,5 kW.h/m2, si convertimos este dato a energía, es equivalente de 21,6 a 23,4 MJ/m2, lo cual es provechoso para el proyecto.Palabras clave- Energía solar, irradiancia, sistema fotovoltaico y energía eléctrica. ABSTRACTThrough this work we explain a method to provide electrical power to a group of people living in the district of San Borja - Lima, through a PV system, which is not common in the area. This would help to reduce emission levels of carbon dioxide (CO2) to the atmosphere. It has been determined by the Solar Atlas of Peru that the coast region solar power reaches 6 to 6,5 kW.h/m2 per day, average in the month of March, if we convert this data to energy is equivalent to 21,6 to 23,4 MJ/m2, which is of great advantage for the proyect.KeyWords.- Solar energy, irradiance, photovoltaic system and electric power.
Estado del arte sobre métodos para modelar la arquitectura de datos de un sistema de información
Authors: Reyna Monteverde Tino Eduardo
Published: March 2017

En este artículo se detallan las investigaciones más recientes respecto al tema del presente trabajo de investigación,“Método de Modelado de Arquitectura de Datos que asegure Robustez y Estabilidad”. La estructura del artículo se ha organizado en dos bloques principales:A. Modelado de DatosB. Métodos de Modelado de Datos

Estos temas constituyen las líneas maestras de la presente investigación. Determinar con claridad el concepto y actividad de modelado es fundamental para soportar todo el desarrollo del método. El análisis de datos es otro de los temas críticos, por la misma naturaleza de esta etapa que no es operativa sino reflexiva. Muchas veces el personal técnico la evita por ser tediosa de allí la importancia de hallar alguna técnica rigurosa y sobre práctica,pero que posea sentido para el área de negocios. Finalmente como todo sistema de información comercial va dirigido hacia la empresa, se debe tomar en cuenta los patrones empresariales para fusionarlo con el modelo tecnológico.

ABSTRACTOBJECTIVES: To compare the efficacy and safety of intravaginal administration of misoprostol  alone versus misoprostol and  isosorbide mononitrate for cervical ripening and labour induction.MATERIAL AND METHODS: One hundred women with term gestation,  Bishop  score <4 with various indications for labour induction were randomly divided into two groups. In Group I, 50 µg of misoprostol tablet was placed intravaginally, 4 hourly maximum upto 4 doses. In Group II,50 µg of misoprostol tablet with 40mg of isosorbide mononitrate was placed intravaginally in posterior fornix upto 4 doses.RESULTS: Two groups were similar in their clinical characteristics. The induction to delivery interval  was 20.8±2.9 hours vs 14.2±2.7 hours in two groups respectively. Misoprostol and isosorbide mononitrate was associated with a shorter induction to delivery interval, decreased oxytocin requirement higher rate of  vaginal delivery i.e 62.8% Vs 53.9% . Uterine hyperstimulation was more common with misoprostol. Neonatal outcome was similar in both the groups.CONCLUSION: The present study suggests that both intravaginal misoprostol and combination of isosorbide mononitrate and misoprostol are safe and effective modes of labour induction. Isosorbide mononitrate and misoprostol is more effective than misoprostol alone in terms of  shorter induction to active phase interval and induction to delivery interval.
