THE PERFORMANCE OF HANDLOOM WEAVERS IN CHITTOOR DISTRICT OF ANDHRA PRADESH - A STUDY
Authors: Ananda Thapai , Prathap G.
Published: December 2020

Indian economic development has to be viewed in the light of the socio-economic factors, preservation of the traditional skills of the people and the use of the available resources. Handlooms have a great potential in this regard as they hold the key not only for sustaining the existing craft persons but also for providing gainful employment, both full-time and part-time, to increasingly larger sections of the economically poor and dispossessed weavers. Village and cottage industries to which the handloom industry belongs are oriented towards balanced socio-economic development of our country owing to the built-in mechanism that encourages weavers and craftsmen to seek an honorable place in the society. He advances raw materials and also cash, pays wages to the weavers on the condition that the weavers should supply him fabrics of a particular design. Weaving may be done on the looms owned and installed by the master weaver at his place or at the residence of the weaver or on the looms owned by the weaver and installed in his home. There is another class of master weavers, who can strictly be called middlemen, as they do not engage themselves in weaving, but have concentrated more on supplying of yarn and cash and marketing of cloth. The cost of inputs has been increased from 2014-15 to 2007-2008 regardless of number of looms. Moreover, higher the number of looms higher is the expenditure towards the cost of inputs. The ‘F’ value is significant at 1 per cent level and confirmed that there are variations in the cost of inputs among the respondents of varied number of looms. The net income of the respondents of 1-4 looms and 10 and above has gradually increased, but the income is low for respondents of 4-10 looms in 2017-2018 owing to their dependency even on some other subsidiary activities which are more fetching. The income has gradually increased and higher the number of looms higher is net income.

Published: December 2020

Introduction Dialysis forms the cornerstone of therapy for most patients with chronic kidney diseases stage V, End Stage Renal Disease (ESRD) and many patients with Acute Kidney Injury (AKI). Congenital disorders, including congenital anomalies of the kidney and urinary tract (CAKUT) and hereditary nephropathies, are responsible for about two thirds of all cases of CKD in developed countries, while glomerulonephritis in developing countries predominates as cause for CKD. Most paediatric patients continue to have haemodialysis till a source becomes available for renal transplant, some may die waiting kidney transplant due to complications and some might change dialysis centre at parents wish.
Aims To identify the causes of Chronic Kidney Disease in children and to assess the outcome and impact of paediatric haemodialysis on Growth parameters and on laboratory parameters.
Materials And Methods this study is Prospective observational hospital based study done at Pediatric hemodialysis centre at Department of Pediatrics and Neonatology, Batra Hospital and Medical Research Centre, New Delhi. Patients coming to Batra hospital for pediatric maintenance hemodialysis were study subjects. A total of 50 patients were taken up for study. Detailed history taking, clinical examination and relevant investigations of subjects were done. Dialysis had been performed with Fresenius 2008K machines and hollow fiberpolysulfone dialysis filters (Fresenius, Bad Homburg, Germany), using standard bicarbonate dialysis solution. Following hemodialysis procedure the child was followed till the end point.
Results . Our study showed prevalence of CKD more in males. In our study out of 50 cases 27(54%) cases wer found to be having glomeruolnephritis as a cause of CKD. In our study out of 50 cases :30 (60%)cases were followed till the end of study 9 (18%)cases terminated dialysis on parent’s wish and dialysis may be continued at another centre.6 (12%)cases died during the study period And 5 (10%)cases underwent renal transplantation. Height improved on follow up and lab. Parameters like Hb,phosphate,crea also improved.
Conclusion This study showed that in developing countries set up most common cause of CKD in paediatric age group is Glomerulonephritis followed by CAKUT and other congenital anomalies of urinary tract. Haemodialysis in children improves height, anemia, and other lab. Parameters like phosphate, creatinine and others. Most paediatric patients followed maintenance haemodialysis till end of study, some died, and some shifted to other haemodialysis centre while about 10% cases underwent kidney transplantation. There is a greater need for establishing multiple pediatric haemodialysis centres all over India, including rural set up for increasing the long term survival in pediatric patients with CKD ,ESRD and improving their quality of life.

Rice bodies are fibrous bodies resembling grains of rice. They are associated with many inflammatory conditions like rheumatoid arthritis, tuberculosis, juvenile arthritides, seronegative arthritis, osteoarthritis, septic joints and chronic bursitis. Rice bodies are seen in pleural fluid, in the setting of bursitis and within the tendon sheath. We describe a rare case of Rice body tenosynovitis of flexor tendon sheath of a finger in a hand that showed no evidence of any infection or rheumatic disease after repetitive diagnostic procedures.
Case presentation: We report a case of forty-nine-year-old fisherman presenting with progressive, painless sausage shaped swelling of right hand middle finger for two years.
Discussion: Rice bodies are formed in inflammatory joint diseases and mostly with tuberculous etiology but rarely found in non-tuberculous patient. This a case of Rice body formation associated with chronic Nonspecific tenosynovitis of middle finger right hand.
Conclusion: Rice bodies in the distal palm to digital flexor tendon sheath of Right-hand middle finger with no specific etiology are extremely rare clinical Presentation. MRI, radiography and histopathology were useful in arriving at a Diagnosis.
Over the period of 10 years, only one flexor tendon sheath of right hand middle finger was affected, without any other disability. Since his occupationis fishing, may be bite of the fish may be a reason. This chronic inflammation of the middle finger tendon sheath of the flexor tendon was confined only to that finger over the past 10 years. Now after complete excision of the sheath, he is free of this problem and is able to continue his profession without any difficulty.

Published: December 2020

Globe is going through a never seen devastating pandemic of COVID-19 since December, 2019. Now, after a span of six months, COVID-19 is no more new and many characteristics of the virus, it’s path physiology, clinical features, disease progression and management came forth. This is truly remarkable and we salute to the global fraternity. We learnt a many. Disease course is defined as of continuous 10 days, if everything else is normal. Third to eighth day is the defined risk period and ninth to twelfth day is the period of deterioration in symptomatic. Symptoms developing after 21 days defined to be recurrence and no such definite incidents is yet detected. To the contrary of all the cases we find in our day to day practice in different COVID centers, here is an anecdote case report of an elderly doctor with two definitive peaks of symptoms within the defined disease course of 10 days, which is unique and not reported elsewhere till date. Sore, wet and tingling nose along with night sweat with or without fever are the earliest and most consistent features of covid-19 as we found in this case report and later confirmed by analyzing in all other cases where most of the cases reported these symptoms.

Authors: Bhargavi Chandana , Kadur Kishan , K Kunal
Published: December 2020

There is very well established association between heart rate variability and heart diseases related mortality and morbidity. Sympathetic activity increases and parasympathetic activity decreases whenever there is decrease in autonomic modulation of heart. These changes are seen in population with increased cholesterol and in other diseases. The aim of the present study is to probe the relation between HRV and cholesterol in geriatric population and effect of sympathetic and parasympathetic stimulation on ANS in them. Material and methods: Serum cholesterol of 27 subjects was less than 200 are grouped as group1 and remaining 18 whose cholesterol was above 200 are grouped as group2, when HRV of these two groups analyzed. Discussion: In geriatric population HRV of subjects with high cholesterol was higher than those with less cholesterol during normal 5 minutes recording of HRV in our study. This finding is not significant in our study. During deep breathing and cold pressor test, subjects with lower cholesterol had higher HRV compared to those with higher cholesterol levels. Conclusion: In geriatric population, cardiac health is better in population with lower cholesterol levels and they have a better autonomic response to both sympathetic and parasympathetic stimulation. Treating geriatric population with lipid lowering drugs may help them to improve their cardiac health.

MULTIPLE CROSS-BORROWING TRENDS AMONG MICROFINANCE BENEFICIERIES: AN ANALYSIS OF PERSONAL AND ENTREPRENEURIAL FACTORS
Authors: A T Athira , Idicula Ebby Joseph
Published: December 2020

Cross borrowing is the ability of a beneficiary to borrow from different lenders simultaneously or borrows from one lender to make repayment to another debt.The commercialisation of the microfinance sector leads to an increased competition for attaining clients and strict objective to seek profitability, that results in more than one Microfinance Institution (MFI) operating in an area. The rapid growth among microfinance sector offers its beneficiaries a scope to borrow from multiple sources, with easy formalities, within short period of time.While various studies acknowledged that the multiple memberships of credit sources among rural clients makes repayment difficulties and collaboration of total economic sustainability of clients. This paper tries to analyse and enlist some personal, entrepreneurial and microfinance provider related factors which leads them to simultaneous multiple accessing of credit from various sources. The paper concludes that the adverse income shocks in general economic conditions of the client, improper investment of fund, low return from the investment, new commercialised lending pattern of MFIs are the major reasons of simultaneous multiple borrowing trend among microfinance clients.

Authors: Pandit Pradipta , Bhuyan Tanmoy , Kushwaha Rahul
Published: December 2020

Background: One of the common cause of emergency surgery in India is peritonitis due to hollow viscous perforation. The morbidity and mortality of secondary peritonitis remains high despite advances in surgical skills, antimicrobial agents and supportive care. Many factors determine the prognosis and outcome which includes patient related factors, disease specific factors and management of the case. Management of these case are done by categorizing patients into different risk groups. Based on measuring simple clinical parameters in case of hollow viscous perforation Mannheim peritonitis index (MPI) is calculated. To know efficacy of MPI for predicting morbidity and mortality in hollow viscous perforation this study was conducted.
Methods: 50 patients who were undergoing surgical treatment for peritonitis following hollow viscous perforation at Silchar Medical College and Hospital, Silchar were included in study. Clinical data, surgical treatment, outcome were documented and analysed.
Results: In patients with MPI more than 29 the morbidity and mortality rate were higher. The most common complication in patients with MPI less than 21 was surgical site infection while of those with MPI more than 21 the respiratory complications were common. The ICU stay of the patients were increased if the MPI Score was higher.
Conclusions: MPI is simple and effective in predicting morbidity and mortality in patients with hollow viscous perforation and is very easy to calculate.

Background: Under-five children are more vulnerable to malnutrition especially in rural areas resulting in more morbidity and mortality among them. The present study is aimed to assess the prevalence of malnutrition among children of 1-5 years of age in tribal hamlets of Valparai block, Coimbatore district in Tamil Nadu.
Methods: A community-based, cross-sectional study was conducted among 95 children in the age group of 1-5 years during December-January 2020. Anthropometric measurements were taken. The indicators of nutritional status of children like stunting, underweight, and wasting were expressed using WHO growth standards.
Results: The overall prevalence of malnutrition in our study was 31.6%. Among the 30 (31.6%) malnourished children, 40% were underweight, and 6.67% were severely underweight. 40% were stunted, of which 13.3% were severely stunted. Wasting was present in 23.3% of malnourished children. Severe wasting was not seen. Socio-demographic factors including the type of house, maternal education, BMI of the mother, age of mother at childbirth and place of delivery had significant association with malnutrition among under-five tribal children.
Conclusions: Malnutrition poses a serious threat to under-five children. Though many known risk factors of malnutrition have been studied, understanding the local factors linked with malnutrition is so crucial while planning information, education, and communication programs in this area.

A STUDY ON DIAGNOSTIC ACCURACY OF ULTRASOUND GUIDED FINE NEEDLE ASPIRATION CYTOLOGY FINDINGS WITH HISTOPATHOLOGY FINDINGS IN NODULAR GOITER OF THYROID
Authors: Sarkar Sudhansu , Mallick Mintu
Published: December 2020

The word ‘Thyroid’ originated from ‘Thyreos’, a Greek word meaning shield. It was first used by Thomas Wharton(1614-1673) of London, UK. He named it as Glandularis thyroideis in 1656 in his book “Adenographia.” In old times, it was called Struma(Latin word of swollen gland), bronchocele (a cystic mass in the neck) and goiter (Latin word-gutter meaning throat).The last name is in use even today [1] .Diseases of the thyroid gland are common and comprise a spectrum of entities causing systemic disease (Grave’s disease) or a localised abnormality in the thyroid gland such as nodular enlargement (goitre) or a tumour mass. After diabetes mellitus, the thyroid gland is the most common organ to cause endocrine disorders [2]. Thyroid disorders are the most common endocrine diseases particularly in countries where iodine intake through diet is low.
PERCEPTION OF PARENTS IN USING MESSY PLAY IN SENSORY BASED INTERVENTIONS
Authors: Parveen Sheeba , Samnani Manish
Published: December 2020

Background:
The word messy is often given negative meanings and calling an important aspect of play 'messy' can lead to it being undervalued. Messy play involve children using all their senses in the process of exploration especially the sense of touch offering children plenty of opportunity to mould and manipulate materials not having a focus on making or producing something.
Objectives: To explore the perception of parents in regard to messy play questionnaire filled by Occupational Therapist who works with Parents of children having Autism Spectrum Disorder.
Study Design: Survey method
Methods: 30 Occupational Therapist who are working in an Early Intervention Centre across Delhi, have filled a questionnaire about “Perception of Parents about Messy Play in Sensory Based Programs”. The questionnaire was created using Google form and its reliability and validity was tested.
Results: The results of the study suggest that parents use messy play during sensory based intervention in home programs occasionally.70 percent of parents suggest using other sensory based equipment’s in comparison to messy play. 80.7 percent of the Occupational Therapist feels that only some of the parents actually do the activities related to messy play.
Conclusion: This study shows that Messy play though the cheapest form of intervention with most wide used possibilities of exploration is still not preferred by many parents. Despite all the contributions messy play can make to children's learning and development there does seem to be a reluctance to promote messy play in the home based settings, neglect of such play may be connected with other people's anxieties about children making a mess and its associations with words such as muddled, confused and shambolic. This has led to this type of play being seen as unimportant and undervalued.

Cost Function based Soft Feedback Iterative Channel Estimation in OFDM Underwater Acoustic Communication
Authors: Qiao Gang , Babar Zeeshan , Ma Lu , Li Xue
Published: December 2020

Underwater Acoustic (UWA) communication is mainly characterized by bandwidth limited complex UWA channels. Orthogonal Frequency Division Multiplexing (OFDM) solves the bandwidth problem and an efficient channel estimation scheme estimates the channel parameters. Iterative channel estimation refines the channel estimation by reducing the number of pilots and coupling the channel estimator with channel decoder. This paper proposes an iterative receiver for OFDM UWA communication, based on a novel cost function threshold driven soft decision feedback iterative channel technique. The receiver exploits orthogonal matching pursuit (OMP) channel estimation and low density parity check (LDPC) coding techniques after comparing different channel estimation and coding schemes. The performance of the proposed receiver is verified by simulations as well as sea experiments. Furthermore, the proposed iterative receiver is compared with other non-iterative and soft decision feedback iterative receivers.
Opto-Electronic Oscillator with Mach-Zender Modulator
Authors: Smolskiy Sergey , Bortsov Alexander
Published: December 2020

The non-standard opto-electronic oscillator (OEO) operation is discussed in the generation mode of a single-side optical harmonic on the base of external and internal modulation of the laser signal. The OEO mathematical model is formed basing on laser differential equations for the closed radiofrequency network. With the help of the model offered, the phase noise of OEO radiofrequency oscillations is analyzed. It is shown that phase noise reduction in the circuit with external modulation depends not only on the increased laser power and growth of the geometric length of the optical fiber, but on reduction of the laser phase noise.

Like every measurement system, optical distance measurement can have errors. Six Sigma tools can evaluate the measurement system and can give useful data about its accuracy. Sometimes measurement system evaluation is done twice. First, initial tests are done, after some fine tuning and error correction is performed, and finally a repeated test is done, to show that the measurement errors were corrected.
Adelskap forplikter: Norges deltakelse i Unescos skoleforsøk 1953–1959
Authors: Sæle Christian
Published: December 2020

Noblesse Oblige: Norway’s Participation in Unesco’s Educational Experimental Program 1953–1959. In 1953, Unesco initiated a teaching experiment project, “Co-ordinated Experimental Activities in Schools of Member States of UNESCO,” with object to develop an effective and coherent, cross-national “education for peace.” Norway was one of 15 countries that accepted the invitation, and put great effort into the project on a national level throughout the 1950’s. Where earlier research has focused on the hands-on implementation of the experiments, this article targets the background and motivation for the Norwegian participation. By focusing on key participants and organizational structures framing the experiments, the article argues that the Norwegian efforts to a significant extent should be seen as part of a broader Norwegian policy towards building cultural relations with other countries. An overall ambition for this policy was to promote the Norwegian educational system as an expression of a particular Norwegian democratic and peace building tradition. This also reflected a self-image that resulted in much of a noblesse-oblige-approach towards Unesco, where Norway, together with its Nordic counterparts, felt obligated to offer their assistance.

Avaliação da eficiência hidrológica por meio da implantação de técnicas compensatórias em loteamento urbano
Authors: Martins de Menezes Filho Frederico Carlos , da Silva Araújo João Marcos
Published: December 2020

Diante do atual cenário de drenagem urbana no Brasil, com a ocorrência de problemas associados à impermeabilização do solo em meio urbano, o presente trabalho avaliou a eficiência hidrológica obtida por meio da implantação de telhados verdes e pavimentos permeáveis num condomínio no município de Franca-SP. Tal eficiência foi obtida pela comparação entre volumes escoados superficialmente, considerando a configuração atual do loteamento e de três configurações hipotéticas pela utilização das técnicas compensatórias isoladas ou associadas. As simulações foram realizadas utilizando o Método Santa Bárbara, considerando também as variações de umidade do solo e diferentes cenários de precipitações. Os resultados de eficiência hidrológica foram positivos, sendo que na configuração em que se combinam os telhados verdes aos pavimentos permeáveis obtiveram-se eficiências da ordem de 12,61% a 73,01%, em que o primeiro valor ocorre em condições de solo saturado e o segundo em solo seco. Deste modo, ressalta-se a aplicabilidade desses mecanismos, com reduções expressivas de vazões que podem contribuir para o alívio dos sistemas de drenagem urbana e para a redução dos índices de ocorrência de enchentes em meio urbano.

Published: December 2020

A contribuição de efluentes domésticos e agrícolas tem sido responsável pelo aumento da concentração de nutrientes nos corpos hídricos superficiais. O presente trabalho propôs desenvolver e aplicar um modelo matemático para a simulação de nitrogênio e fósforo em sistemas de recursos hídricos. Os procedimentos matemáticos são realizados em duas etapas principais: a modelagem de nitrogênio e fósforo nas áreas agrícolas e a definição de sistemas de equações diferenciais ordinárias que permitam quantificar a concentração desses nutrientes nos corpos hídricos. O modelo foi aplicado em um sistema na região do alto curso do rio Piranhas - PB, levando em consideração rios, reservatórios, efluentes domésticos e agrícolas. Os resultados das simulações indicaram que os recursos hídricos são impactados significativamente pela ação dos efluentes, principalmente nos períodos de maior déficit pluviométrico, onde o volume dos reservatórios e as vazões nos trechos dos rios são reduzidos. Medidas preventivas e corretivas devem ser adotadas para esses tipos de sistema, de maneira a evitar o comprometimento da biota aquática e dos múltiplos usos aos quais as águas são destinadas. Desta forma, o modelo desenvolvido mostrou-se importante na quantificação da dinâmica comportamental de nitrogênio e fósforo em sistemas de recursos hídricos, possibilitando uma análise integrada dos principais fatores intervenientes nos seus ciclos.

Authors: Kuhnen Mirian , Ceriotti Toassi Ramona Fernanda , Ceccato de Lima Lucia
Published: December 2020

A fluoretação da água é uma questão de saúde pública, com dimensões complexas e interdisciplinares haja visto que as concentrações variáveis quanto aos valores recomendados podem causar danos à saúde da população. Com objetivo de sistematizar o conhecimento das publicações sobre o heterocontrole da fluoretação da água de abastecimento público no Brasil, foram conduzidas uma revisão integrativa nas bases de dados eletrônicas e uma busca livre na lista de referências de artigos publicados no período de 1990-2016. Baseado nos 55 artigos selecionados foi detectada disparidade regional nas publicações e não-uniformidade metodológica. Verificaram-se oscilações nas concentrações de fluoreto, com tendência à subdosagem, possivelmente explicadas pela rede de distribuição complexa, técnica analítica diferente entre controle interno e externo e falhas no campo operacional. Evidenciaram-se dificuldades na manutenção da concentração ótima de fluoreto nas águas de abastecimento público, justificando o aprimoramento do heterocontrole e de pesquisas que apontem os fatores associados às oscilações dos teores de fluoreto. Palavras-chave: Fluoretação. Vigilância em saúde. Qualidade da água.

Erosion of forest soil under conditions of higher precipitation and snow melt (case study central part of the Moravskoslezské Beskydy Mountains)
Authors: Buzek Ladislav
Published: December 2020

Water erosion is an important degradation agent not only on the agricultural land but it also shows up on the forested soil. It is associated with the progress of forest mechanisation and with changing forest cover and occurs especially under exceptional hydrometeorological situations. Intensive water erosion is often combined with gravitation processes (landslides). Research of water erosion has been organized by the Department of Physical Geography and Geoecology of the Ostrava University since 1976 in the central part of the Moravskoslezské Beskydy Mountains (especially in the basin of the Upper Ostravice River). The article shows results of analysis of suspended load regime between 1976 and 1998. Suspended load as a transition part of the erosional products is an evidence of the intensity of erosional processes of the observed catchment.

Contribution to the theory of polarized development of a territory, with a special attention paid to peripheral regions
Authors: Havlíček Tomáš , Chromý Pavel
Published: December 2020

The article makes a survey of aspects for evaluation of a periphery in geographic sciences. The definition of the terms "periphery" and "marginality" is discussed. An attention is paid to evaluation aspects and types of polarities defining peripheries. A periphery is understood as a consequence of an asymmetry in organization of a territory, a society, etc. The article takes into account the development of the relation core/centre - periphery and, in their delimitation, differentiates the objective and the subjective viewpoints. Determining factors and actors' behaviour in the framework of the development of peripheries, or their individual types, are observed.
