Disparity in Spatial Access to Public Daycare and Kindergarten across GIS-Constructed Regions in Seoul, South Korea
Authors: Kim Hyunjoong , Wang Fahui
Published: October 2019

In developed countries with decreasing fertility rates, the provision of public daycare and kindergarten (PDK) is considered to be an important policy for boosting national birth rates. Since PDK is free, its spatial accessibility becomes the most critical factor for parents in choosing the service. The study uses the popular two-step floating catchment area model (2SFCA) to analyze the spatial accessibility of PDKs at a 100 m × 100 m cell level in Seoul, South Korea. A GIS-automated regionalization method, Mixed-Level Regionalization (MLR), is employed to divide the study area into homogenous regions based on a concentrated disadvantage index (CDI). The analysis then proceeds to examine the disparity of PDK accessibility across these constructed regions. The result empowers parents to be informed of the access of PDKs in their current neighborhoods or to look for neighborhoods with adequate access. Several policy measures are proposed for improving overall accessibility of PDKs and more so for underserved populations.
Paramagnetic versus Diamagnetic Interaction in the SU(2) Higgs Model
Authors: Antonov Dmitry
Published: October 2019

We present an analytic calculation of the paramagnetic and diamagnetic contributions to the one-loop effective action in the SU(2) Higgs model. The paramagnetic contribution is produced by the gauge boson, while the diamagnetic contribution is produced by the gauge boson and the ghost. In the limit, where these particles are massless, the standard result of −12 for the ratio of the paramagnetic to the diamagnetic contribution is reproduced. If the mass of the gauge boson and the ghost become much larger than the inverse vacuum correlation lengths of the Yang–Mills vacuum, the value of the ratio goes to −8. We also find that the same values of the ratio are achieved in the deconfinement phase of the model, up to the temperatures at which the dimensional reduction occurs.
Heat Transfer Analysis of a Magneto-Bio-Fluid Transport with Variable Thermal Viscosity Through a Vertical Ciliated Channel

Published: October 2019

We communicate the responses of various physiological fluids containing hemoglobin and other ionic constituents when they propagate in the presence of an electromagnetic body force field with the mechanisms of heat generation and conduction. A fully developed mixed convective flow of a Newtonian fluid takes place through a 2D vertical channel in the presence of an external magnetic field acting in the direction normal to the flow. The inner surface of the channel is carpeted with a thick mat of cilia, which propagates a sinusoidal metachronal wave travelling in the direction of flow. Coupled, nonlinear governing Naiver-Stokes and temperature equations are simplified by utilizing the creeping flow and long wavelength approximations. This enables us to formulate the exact analytical solution of the temperature distribution; whereas, the velocity distribution is evaluated from the momentum equations by using the Adomian decomposition method. In order to determine the pumping characteristics, the formulae of volume flow rate and the pressure rise are also obtained. Trapping due to the ciliary system is highlighted by graphing the stream function. The findings of the present model have significant outputs, which can be applicable in the physiological transport of human semen through the male reproduction system.
Hydrogen and Oxygen Isotope Composition and Water Quality Evaluation for Different Water Bodies in the Ebinur Lake Watershed, Northwestern China
Authors: Zhu Shidan , Zhang Fei , Zhang Zhaoyong , Kung Hsiang-te , Yushanjiang Ayinuer
Published: October 2019

Wetlands are sensitive indicators of climate change and have a profound impact on the supply of water resources in surrounding areas. In this study, the hydrochemical, isotopic characteristics (δ18O and δ2H) of groundwater and surface water (lake, reservoir, and river) in the Ebinur Lake Watershed, northwestern China, were investigated to reveal the relationships between various water bodies. The results suggest that the groundwater is alkaline and has pH and total dissolved solids (TDS) values less than those of surface water. Ca2+ and SO42− are the major ions in the groundwater and river water, whereas lake water and reservoir water are enriched in Na+ and SO42−. With the decrease in elevation, both groundwater and river water are affected by carbonate dissolution at high elevation and by evaporitic rock dissolution at low elevation; thus, the water surrounding Ebinur Lake is subjected to runoff affected by intense evaporation–dissolution of evaporitic rocks. The stable isotope compositions suggested that the upstream part of the river is recharged by glacial meltwater from high mountains, whereas the middle–downstream parts of the river are recharged by low-elevation precipitation. Shallow groundwater and reservoir water are mainly recharged by river water and are more enriched in the downstream part of river. Water samples were also classified according to different indices, such as chemical oxygen demand (COD), NH3-N, volatile phenol, sulfate, Zn, Co, Cu, total hardness, and Cr6+, and results showed that most groundwater is suitable for drinking and irrigation purposes. Except for Cr6+, the metal concentrations are within permissible limits. However, both groundwater and reservoir water are affected to some extent by nearby rivers from anthropogenic activity.
Assessing the Potential for Potable Water Savings in the Residential Sector of a City: A Case Study of Joinville City
Authors: Custódio Diego Antônio , Ghisi Enedir
Published: October 2019

The objective of this study is to evaluate the potential for potable water savings by using rainwater in the residential sector of Joinville, a city located in southern Brazil. Data on roof areas of residential buildings were obtained from the Joinville city council. By considering the roof areas and typologies of residential buildings, representative models were created. The following parameters were used to determine the rainwater tank capacity: the number of dwellers; the total daily water demand per capita; and the rainwater demand. To carry out the simulations for determining the optimal rainwater tank sizes and potential for potable water savings, the computer program Netuno was used to run 33,720 different scenarios. By considering the occurrence percentage for each representative building model (weighted average), the average potential for potable water savings by using rainwater was calculated. The average potential in the central region of Joinville was 18.5% when there is rainwater use only in toilets, and 40.8% when there is rainwater use in toilets and washing machines. The rainwater harvesting system showed a better performance for a rainwater demand equal to 20% of the total daily water demand. The results indicate the necessity to properly size rainwater tank capacities to meet water demands, thereby encouraging more people to adopt rainwater harvesting as an alternative source for non-potable water in buildings. The demand for rainwater should be carefully evaluated, especially in multi-story residential buildings, due to the low availability of roof areas.

Une paragenèse à staurotide et tschermakite d'Ovala (Gabon)
Authors: Demange Michel
Published: October 2019

Au sein des roches métamorphiques banales de la série de l'Ogooué (Précambrien I), la région d'Ovala (centre Gabon) montre des roches assez exceptionnelles par leurs associations minérales et le chimisme de leurs minéraux. Parmi celles-ci, se distingue une paragenèse à quartz -plagioclase -biotite -chlorite -grenat -amphibole et staurotide -tourmaline -ilménite -magnétite -pyrrhotite -chalcopyrite dans laquelle la staurotide contient jusqu'à 2 % de Cr₂O₃ et 1,40 % de ZnO et la magnétite jusqu'à 15 % de Cr₂O₃.

Il est démontré — à l'aide des coefficients de partage entre autres — que ces associations sont bien des paragenèses en équilibre et que le caractère particulier de ces paragenèses vient d'un chimisme déjà particulier avant le métamorphisme. Une hypothèse possible est que ces roches soient d'anciennes roches éruptives ayant subi des altérations hydrothermales .

L'article discute plus longuement les facteurs déterminant l'apparition des différents minéraux et fait ressortir le rôle du manganèse dans la cristallisation du grenat, du zinc et du chrome dans celle de la staurotide.
Study of the Interaction Between Common Carp (Cyprinus carpio L.) and Silver Crucian Carp (Carassius auratus gibelio B.)
Authors: Bársony Péter , Pócsi László , Szabó András
Published: October 2019

During the last few years, the spread of the silver crucian carp caused significant problems in pond fish culture. One of the main challenges of the successful fish production in fishponds, is to rid ponds of the silver crucian carp. In the course of the experiment, carp fry were stocked in 5 nursing ponds at the same stocking rate, with different (0-, 50-, 100-, 150-, 200%) stocking rates of silver crucian carp fry, respectively. During the breeding season, weekly test fishings were made to examine the growth of the fishes. At the end of the experiment, the yield/hectar and the growth rates were calculated. The experiment proved that the presence of the silver crucian carp in the fishponds causes lower productivity and growth rates in common carp. In the control pond (with no silver crucian carp), the average weight of the common carp was over 20 g and the yield/hectar was over 700 kg, while in the pond with the most silver crucian carp, the average weight of the common carp was 4.5 g and the yield/hectar was only 123 kg.

Ile de France, Suffolk and Babolna TETRA breeding ewes gave the data for the further evaluation. The main aim of this research was to find out if there is any significant effect of selected parameters (registration class, lambing season, lambing type and the years) on the lambing frequency, the period between consecutive lambings. Production parameters of 9,471 Ile de France, 1,244 Suffolk and 7,618 Babolna TETRA ewes were collected and processed. The analysis covered the period between the years 1989-1999. It was concluded that not all of the evaluated parameters had a significant effect on lambing frequency. Not all of the genotypes showed significant differences, according to the examined parameters.
The Effect of Plant Density on the Yield of Sunflower Hybrids in 2000-2002
Authors: Szabó András , Pepó Péter
Published: October 2019

In order to ensure modern Hungarian sunflower production, the development of hybrid-specific techniques are highly important. The continual expansion in hybrid choice makes the examination of genotypes necessary in the relation of genotype and environment interactions and critical factors. The Plant density as a complex determinant factor has a strong effect on sunflower yield, quality and plant hygiene. As a result of the experiments, we can state that the optimal density was 45.000-65.000 plant/hectar. In 2001-2002, the optimal density was 45.000-55.000 plant/hectar; while in 2000, it was 65.000 plant/hectar.
The Target Areas of Regional Development, Tool and Institutional Background, its Present and Future Prospects
Authors: Harsányi Endre
Published: October 2019

Regional politics determines the aims of regional structures, and the tools with the institutional background on the whole necessary achieve these. Realizing the aims of regional politics is a precondition of executing the basic principles of regional development and politics. The regional institutional system for handling the decentralized financial resources has not evolved in Hungary yet. The professional institutes for preparing the programs have not been set up, and the management of execution is slowly taking shape. There are still deficiencies in the domestic application of concentration and addition principles. A number of funds are provided on a national level, that are directly or indirectly aimed at regional development. The obvious coordination among the funds is not carried out neither on a national, nor on a regional level, partly to avoid parallel consumption aims. The future of Hungarian spatial structure depends on the type of decentralization strategy the country will follow for the new resources after the accession. Total decentralization offers the most efficient solution for Hungary.
Current Conditions and Opportunities of Biofarming in Hungary
Authors: Nagy Petra
Published: October 2019

The aim of organic farming is not to maximize income, but to achieve optimal product quality. It is completed by the tightest possible material, and energy flow within the farm. Organic agriculture significantly reduces external inputs by avoiding the use of chemo-synthetic fertilizers, pesticides and pharmaceuticals. Instead it works with nature to increase both agricultural yields and disease resistance. Total independence of external resources can not be achieved in Hungary due to the small-scale of organic animal husbandry. Some materials in limited quantities can be purchased from external resources, though the group of these materials is strictly regulated. Organic farming harmonizes with the concept of European multifunctional agriculture, because besides farming, it includes social considerations, as it helps to maintain natural resources and the relationship between people and their environment, and provides a living for those living in the region.As regards organic farming the fertility of the soil and the health of vegetation can be influenced in various ways. Farmers have to be highly skilled and able to manage a farm with great expertise. Generally it can be stated that as the use of non-organically produced products is limited, the opportunities to correct failures made by the farmer are minimal, contrary to conventional farming. Farmers must be intent on developing the tightest material- and energy flow. This means that organic farms ideally have both animal husbandry and crop production. This energy and skill demanding system of farming is compensated by state subsidies, growing market share and relatively high prices for organic products.

Estudio de interacciones en moléculas adsorbidas físicamente
Authors:   , Bottani Eduardo Jorge
Published: October 2019

El presente trabajo surge con el interés creciente en el estudio de las interacciones entre moléculas adsorbidas, la influencia que ejerce el adsorbente en ellas y la preocupación por caracterizar la superficie del mismo. Este último aspecto se ve plasmado en los esfuerzos realizados por la IUPAC (1,2) y organizaciones tanto europeas como americanas para lograr este propósito. Todos nuestros estudios se realizan sobre sistemas relativamente sencillos para reducir al mínimo el número de variables que afectan a las propiedades antes mencionadas. Este trabajo, que fuera comenzado hace varios años, y del cual ya se han publicado algunas conclusiones parciales, ha permitido resolver algunas cuestiones, pero al mismo tiempo se han planteado nuevas incógnitas que obligan a continuarlo, mejorando las técnicas experimentales a medida que se avance en el estudio y se requieran otros tipos de datos experimentales para verificar las conclusiones a las que se llegue.
El poder-femme
Authors: Amícola José
Published: October 2019

El presente trabajo intenta poner en relación tres polos culturales: Londres (especialmente entre las décadas 1920-1940), París (entre 1944 y 1950) y Buenos Aires (entre 1930 y 1960), mediante el nexo de tres figuras femeninas que, cada una a su modo, produjeron un cambio significativo a nivel de la cultura en la que obraron; a saber: Virginia Woolf, Simone de Beauvoir y Victoria Ocampo. Estas personalidades descollantes de la primera mitad del siglo XX se interconectan a través de vasos comunicantes que son las empresas editoriales y las publicaciones periódicas ligadas a ellas. En este sentido, operan las casas editoriales de, por un lado, Leonard Woolf con The Hogarth Press para Londres; y, por otro, la revista Les Temps Modernes para París, bajo la dirección de Sartre. El triángulo se completa, en este caso, con la labor de la revista, y luego casa editorial, Sur para Buenos Aires. Se sostiene en esta investigación que los casos a analizar se conforman como “comunidades interpretativas excluyentes”, dado que lo que interesa enfatizar en esos procesos sociales es su poder de exclusión de aquellos otros miembros que no merecen pertenecer al grupo. Entre los excluidos se encontrarán tres varones de renombre: Cyrill Connolly, Albert Camus y Witold Gombrovicz.

Revalorización y gestión del paisaje mesetario-andino patagónico
Authors:   , Cárcamo Javier Audelio
Published: October 2019

En la actualidad se presenta tras la Región Patagónica, un imaginario a nivel mundial que proyecta sobre la misma, la imagen de región “virgen” o poseedora de una “naturaleza pura”, sin embargo este escenario sólo puede ser atribuido a la franja cordillerana y costera de la región. Esta falta de correspondencia, que puede extender determinados atributos a una región a través de sus imaginarios, llama la atención por su poder convocante, pudiéndose decir que la emergencia de los mismos, se forma en un contexto de resurgimiento de los ideales del romanticismo y naturalismo del siglo XIX, promovido a partir del movimiento ambientalista, nacido hace cuatro décadas, y que al presente se extiende mundialmente. En esta región se perciben claramente dos paisajes particulares de la misma, la meseta y la cordillera a través de sus elementos característicos, que incluso en el caso del ambiente mesetario aparentemente monótono registra contrastes internos. Por lo que en el ambiente que domina la extensión de la Región Patagónica, la meseta o gran planicie árida, presenta variaciones, es decir, se fractura y se eleva a manera de grandes bloques, con un sentido ascendente hacia el oeste de la región (alcanzando alturas de hasta 1.000 m.s.n.m.), siendo una de sus características principales la aridez y asociaciones vegetales “en cojín”, que en su conjunto constituyen la típica vegetación esteparia. El contexto de esta investigación se centra en la franja denominada “de transición” (concepto desarrollado en apartado I.3.3) entre el ambiente cordillerano, llamado en el subcontinente americano como “Cordillera de los Andes” y el ambiente Mesetario, por lo que a los fines de la investigación pasará a designarse como paisaje de transición Mesetario-andino.
Desigualdad y educación: la construcción de experiencias escolares en contextos de pobreza
Authors:   , Crego María Laura
Published: October 2019

Esta tesis se inserta en la intersección de los campos de la sociología de la educación y los estudios sobre la desigualdad. Si bien la producción científica en torno a estas áreas es prolífera, la persistencia de desigualdades y el lugar que la escuela ocupa en la estructura social y en la trayectoria de vida de quienes la transitan, hace a la insistencia en la investigación de estos temas. En este marco el propósito de la presente tesis es actualizar la pregunta por la relación entre desigualdad y educación a partir de la comprensión de cómo los y las jóvenes construyen sus experiencias escolares en contextos de pobreza. Definimos las experiencias como construcciones sociales que constituyen maneras de ver, hacer y sentir, en otras palabras, de construir lo real y al mismo tiempo de constituir socialmente una subjetividad propia en el marco de un inventario cultural disponible por parte de actores social y espacialmente situados. De este modo entendemos que toda experiencia tiene una dimensión subjetiva, individual y otra compartida, social de modo que su riqueza analítica reside en el potencial para articular lecturas macro y micro en tanto la comprensión de la experiencia permite tender puentes entre las trayectorias biográficas y los procesos sociales más generales como la polarización, la fragmentación y la desigualdad, que son expresiones sociales de los diversos procesos de acumulación de desventajas. Analizar la experiencia escolar supone entender que los y las jóvenes construyen modos de estar en la escuela en diálogo con otras esferas de la vida. En este sentido analizamos cómo se dan las negociaciones entre lo que la escuela espera de los jóvenes y el modo en que ellos habitan el tiempo y espacio de la institución. Esto conlleva a su vez un diálogo con el modo en que los adultos dan forma a sus propios modos de estar en la escuela y, con ello, al vínculo pedagógico que proponen. A estos fines se realizó una etnografía en una escuela ubicada en un barrio periférico de la ciudad de La Plata (Escuela Secundaria Básica Nro. 54) caracterizado por condiciones de pobreza estructural. El trabajo de campo se desarrolló entre los años 2015 y 2017 en los que se compartieron numerosas jornadas que incluyeron clases, actos, horas libres, reuniones con padres o tutores, encuentros especiales con los estudiantes, entre otras actividades. El desarrollo de esta tesis se sustenta en el diario de campo construido a lo largo de esos años de trabajo.

Background: Since H pylori has been mostly associated with gastritis its presence in other parts of gastrointestinal system has not been studied much. Few previous studies have identified “H pylori” in gallbladder and found its association in causing cholecystitis and gallstones but only a few studies have been performed in Pakistan that have shown a significant association. Therefore, in this study we looked for the presence of this microorganism in cholecystitis patients and its association with the morphological changes seen in gall bladders.

Material and method: All patients with acute and chronic cholecystitis admitted in ANTH between the ages of 18 and 75 years from January 2017 till March 2019, who underwent cholecystectomy, were included in the study. Gall bladder specimens after surgery were sent to Pathology department ANTH and specimens were analyzed for the presence of H pylori bacteria using H&E and Giemsa staining. Signs of inflammation, any hyperplasia, metaplasia, mucosal atrophy or erosion, lymphoid infiltration, fibrosis, cholesterolosis or any other morphological changes were also noted. Association of H.pylori with cholecystitis and other morphological changes were checked by Chi Square analysis. P. value less than 0.05 was considered statistically significant

Results: Chronic cholecystitis was present in 91% cases and acute cholecystitis in 9%. Other histological findings were Hyperplasia (10%), Metaplasia (15%), Fibrosis (79%), Cholesterolosis (19%) and ulcerations (36%). H pylori was found in 17% of gall bladders and all the cases were of chronic cholecystitis. Among these, there were 11.7% Males and 88% Females. Gallstones were present in 76.4% cases and age group involvement was seen more among 41-60 years (64.7%). Other histological findings seen in hpylori positive cases were; Hyperplasia in 11.7% cases, Metaplasia in 17.6%, Fibrosis in 94.1%, cholesterolosis in 23.5% and ulcerations in 17.6% cases. Association of H-Pylori with gender, cholecystitis, gall stones, histological features and age distribution was non-significant.

Conclusion: Although H pylori infection has been found in cases of chronic cholecystitis and gall stone formation, its association with cholecystitis and other morphological changes could not be proved. Hence, it is uncertain whether H pylori eradication in patients with gastritis can prevent cholecystitis or gall stones formation

Background: Tuberculous meningitis (TBM) is difficult to diagnose in early stages due to nonspecific symptoms. There should be high index of suspicion to diagnose TBM at an early stage. The objective of the study was to find out the role of magnetic resonance imaging (MRI) and spinal tap in early diagnosis of tuberculous meningitis.

Material and Methods: A cross sectional study was conducted from July 2015 till July 2018 at Neuromedicine ward, Jinnah Postgraduate Medical Centre (JPMC), Karachi. All patients above 12 year of age, both male and female with nonspecific symptoms like headache, malaise and drowsiness or suspicion of TBM (stage I, II, and III according to British Medical Research Council TBM staging criteria) were included in the study. Patients diagnosed with other CNS disease like encephalitis, malaria and acute bacterial meningitis were excluded. Magnetic Resonance Imaging (MRI) of the brain and early spinal tap for cerebrospinal fluid (CSF) analysis were used to diagnose TBM and findings were noted. Results of MRI and CSF analysis were analyzed by SPSS version 24.

Results: A total of 110 patients of TBM, with 60 (54.5%) male and 50 (45.5%) female patients were included in the study. Most of the patients belonged to a younger age group of 12-40 years (81.8%), while 18.2% were above 40 years of age. About 90% patients were diagnosed in stage I TBM and 10% in stage II and III. MRI brain findings included meningeal enhancement (60%), hydrocephalus (41.81%) cerebral edema (82.73%), tuberculoma (19%) and infarct (14.5%), respectively. CSF analysis showed low protein in 80%, low glucose in 91.8% and lymphocytic pleocytosis in 97.2%, respectively.

Conclusion: Both MRI brain and spinal tap with CSF analysis played a role in the early diagnosis of TBM, which is important to prevent the lethal complications associated with late diagnosis of this disease.

Background: Diarrhea is the second leading cause of mortality in children below 5 years of age in Pakistan. Use of Zinc and ORS has been proven in clinical trials to be beneficial in reducing morbidity and mortality. Poor knowledge regarding home management of diarrhea leads to mortality due to severe dehydration. The objective of this study was to assess the level of knowledge of mothers of under five-year-old children regarding, diarrheal home management in Cantonment General Hospital, Rawalpindi.

Material and Methods: This was an observational cross-sectional study carried out at Department of Pediatrics, Cantonment General Hospital, Rawalpindi, from 1st August, 2017 to 31st January, 2018. About 400 mothers of under five-year-old children, coming to the outpatient department of the hospital were enrolled in this study. A self-designed structured and validated questionnaire was used to assess the level of knowledge of mothers regarding home management of diarrhea using Oral Rehydration Solution (ORS) and Zinc. Data was analyzed using SPSS version 23 with a p value < 0.05 considered statistically significant.

Results: About 91% (n=364) of mothers had awareness regarding use of ORS as a means of diarrheal home management. Regarding level of knowledge variable results were found. A good percentage of mothers had knowledge of the purpose of ORS use (78.3%), administration (60%) and initiation of ORS (68%), but only 20.8% mothers rightly answered the timing of ORS administration. Mothers knowledge about the use of zinc, daily administration and duration of administration (10-14 days) was 38.8% ,20.5% and 17.3% respectively.  Mothers who were more educated especially secondary and above and of the age group 22-31, had better awareness of ORS than others, as P value is less than 0.05. Among mothers who were aware of the use of ORS, only 41.8% of them were also aware of the use of zinc.

Conclusion: A high awareness level regarding ORS use in mothers was reflected fairly in terms of purpose, administration and initiation of ORS but the knowledge of mothers regarding use of zinc and timing of ORS administration, in home management of diarrhea is still lacking.

Abstract: To date, there are lots of documentations about the adverse effects of smoking on the oral cavity. Albeit, smoking is still considered as a casual thing in our community. Chemicals contained in the cigarette smoke can irritate the gums and soft tissues of the mouth, thus inhibiting wound healing after tooth extraction. This study was aimed to determine the difference in post-extraction dental wound healing between smokers and non-smokers. This was a comparative analytical study with a cross sectional design. Samples were obtained by using total sampling method. Subjects consisted of 16 smokers and 16 non-smokers that fulfilled the study eligibility criteria. Their oral cavities were examined to check the signs of inflammation (calor, dolor, rubor, tumor, and functio laesa). The results showed that there was a difference in post-extraction wound healing in inflammatory phase between smokers and non-smokers. As many as 9.4% of smoker patients and 34.4% of non-smoker patients recovered at 7 days post extraction. The Mann Whitney U test showed a p-value of 0.005. In conclusion, there was a significant difference in post-extraction wound healing between smokers and non-smokers.Keywords: smokers, non-smokers tooth extraction, wound healing Abstrak: Kebiasaan merokok bukan merupakan hal asing di masyarakat walaupun banyak dokumentasi mengenai akibat buruk dari merokok terhadap rongga mulut.

Forecasting plays a crucial role in determining the direction of future trends and in making necessary investment decisions. This research presents the forecasting performance of three multivariate GARCH models: SGARCH, EGARCH, and GJR-GARCH based on Gaussian and Student’s t-distribution. The forecasting ability of the models is evaluated on the basis of forecasting performance measures: MAE, SSE, MSE, and RMSE. This is done by examining the hedged portfolios of three indices of NSE: NIFTY50, BANKNIFTY, and NIFTYIT. Daily data from Jan 2006 to Dec 2017 is taken and forecasts are conducted using out of sample data from Jan 2016-Dec 2017. Minimum mean square error (MMSE) forecasting method is used to generate conditional variance and covariance forecasts which in turn generate hedge ratios and corresponding hedged portfolio. Minimum variance hedge ratio framework of Ederington (1979) is used for hedging. The in-sample analysis shows that SGARCH with both the distribution performed better than the other models while out-of-sample analysis provides mixed results. EGARCH model assigns the lowest hedge ratio to NIFTY50 and BANKNIFTY while SGARCH model assigns the lowest hedge ratio to NIFTYIT. Forecasting performance measures show the least value for SGARCH and EGARCH model. In future these models are able to reduce maximum risk from the spot market. The results of this research has important implications for financial decision and policy makers.
