Approaches and Applications for Sentiment Analysis
Authors: Govindarajan M.
Published: November 2021

With the increasing penetration of the internet, an ever-growing number of people are voicing their opinions in the numerous blogs, tweets, forums, social networking, and consumer review websites. Each such opinion has a sentiment (positive, negative, or neutral) associated with it. But the problem is that the amount of data is simply overwhelming. Methods like supervised machine learning and lexical-based approaches are available for measuring sentiments that have a huge volume of opinionated data recorded in digital form for analysis. Sentiment analysis has been used in several applications including analysis of the repercussions of events in social networks, analysis of opinions about products and services. This chapter presents sentiment analysis applications and challenges with their approaches and tools. The techniques and applications discussed in this chapter will provide a clear-cut idea to the sentiment analysis researchers to carry out their work in this field.

Authors: Bektaş Jale
Published: November 2021

Conducting NLP for Turkish is a lot harder than other Latin-based languages such as English. In this study, by using text mining techniques, a pre-processing frame is conducted in which TF-IDF values are calculated in accordance with a linguistic approach on 7,731 tweets shared by 13 famous economists in Turkey, retrieved from Twitter. Then, the classification results are compared with four common machine learning methods (SVM, Naive Bayes, LR, and integration LR with SVM). The features represented by the TF-IDF are experimented in different N-grams. The findings show the success of a text classification problem is relative with the feature representation methods, and the performance superiority of SVM is better compared to other ML methods with unigram feature representation. The best results are obtained via the integration method of SVM with LR with the Acc of 82.9%. These results show that these methodologies are satisfying for the Turkish language.

Published: November 2021

Background:

Hemodialysis in end-stage renal disease patients causes disability in different domains of patient's lives, leading to impaired (quality of life [QOL]). Studies measuring the QOL in patients on renal replacement therapy are limited in the Indian scenario.

Aims:

To evaluate the QOL in adult patients on maintenance hemodialysis by applying the World Health Organization QOL (WHOQOL)-BREF scale.

Material and Methods and Study Design:

Health-related QOL was evaluated in 100 adult patients on maintenance haemodialysis for 3 months or more in Dayanand Medical College and Hospital, Ludhiana. The WHOQOL-BREF was applied in these patients and the physical, psychological, social, and environmental health domains were assessed.

Results:

Most common age group was 31–60 years (56%) with a mean age of 54.44 years, male: 74%. Patients with age more than 60 years had better QOL scores in the social domain which was statistically significant (P = 0.005). Male patients had better scores in all four domains and was significant in the social domain (P = 0.025). Married patients had better QOL scores in social domain. Duration of dialysis had a reverse correlation with QOL scores in physical domain with better scores in dialysis duration of <12 months. Frequency of dialysis did not significantly affect the QOL scores. QOL scores were directly related to the monthly family income in all four domains with the highest income group showing better scores (P < 0.05).

Conclusion:

The present study provided an insight into the factors that affect the QOL in hemodialysis patients. Patients with age >60 years had better QOL scores in the social domain. Female gender, low serum proteins, HD duration of more than 1 year, and low monthly income were found to be associated with impaired QOL domains in patients undergoing maintenance hemodialysis.
Proteomic analysis of the influence of CO2 pneumoperitoneum in cervical cancer cells
Authors: Lv Hongtao , Zhou Ting , Rong Fengnian
Published: November 2021

Objective:

The effect of CO2 pneumoperitoneum (CDP) on the oncology outcomes of patients undergoing laparoscopic radical hysterectomy for cervical cancer remains unclear. In this study, we investigated the effects of CDP on the proliferation of cervical cancer cells and examined the molecular mechanism.

Materials and Methods:

We established an in vitro CDP model to study the effects of CDP on the proliferation of cervical cancer cells by Cell Counting Kit-8 (CCK-8) assay, xenografted tumor assay. Tandem mass tag-based quantitative proteomics were used to study the proteomic changes in HeLa cells after CDP treatment. Western blot assay was used to detect the expressions of PI3K/Akt signaling pathway proteins.

Results:

CDP increased cell proliferation after a short period of inhibition in vitro and promoted tumorigenesis in vivo. Proteomic analysis showed that the expression levels of 177 and 309 proteins were changed significantly 24 and 48 h after CDP treatment, respectively. The acidification caused by CO2 inhibited the proliferation of cervical cancer cells by inhibiting the phosphorylation of PI3K and Akt.

Conclusions:

CDP promoted the proliferation of human cervical cancer cells after a short time of inhibition. The mechanism of which is related to the inhibition of phosphorylation of the PI3K/Akt signaling pathway.

Authors: Kumar N , Gupta S
Published: November 2021

Aim:

To determine the risk factors affecting outcome at the end of 90 days of post-angiogram-negative subarachnoid hemorrhage (SAH).

Methods:

Non-traumatic SAH cases were reviewed from the case records of patients who had reported to the Department of Neurology of a tertiary care hospital and 50 angio-negative SAH cases were included after excluding all the cases with known cause of hemorrhage after doing computed tomography angiography (CTA)/digital subtraction angiography (DSA). The presence of hypertension, diabetes mellitus, coronary artery disease (CAD), history of alcohol and smoking, and various scales like Hunt and Hess Scale (HHS), World Federation of Neurological Surgeons (WFNS), and Fisher scale had been recorded at admission. The outcome was assessed at 90 days post-SAH using the Modified Rankin Scale (mRS).

Statistical analyses:

The association between the outcome and the factors was assessed using the Pearson Chi-Square test and the risk factors/predictors of outcome were assessed using logistic regression.

Results:

The following variables were important risk factors for predicting poor outcome of angio-negative SAH (mRS 3 to 6): hypertension (P = 0.011), diabetes mellitus (P = 0.032), being an alcoholic (P = 0.019), HHS grade 4 to 5 (P < 0.01), and WFNS grade 4 to 5 (P < 0.01). On multivariate regression analysis, hypertension (P = 0.032) was an independent predictor of unfavorable outcome.

Conclusions:

At time of admission, presence of hypertension, diabetes mellitus, history of alcohol consumption, and poor grades of HHS and WFNS scale are predictors of poor outcome of angio-negative SAH.

Authors: Bommannan KB , Naseem S , Binota J , Varma N , Malhotra P , Varma S
Published: November 2021

Introduction:

Despite the impressive responses achieved with tyrosine kinase inhibitor (TKI) therapy, treatment resistance develops in 16–33% of patients of chronic myelogenous leukemia (CML). Of the BCR-ABL1 dependent mechanisms, mutations in the tyrosine kinase domain (TKD) are the commonest cause of resistance.

Material and Methods:

Allele specific oligonucleotide - polymerase chain reaction (ASO-PCR) was done for testing the six common TKD mutations, T315I, G250E, E255K, M244V, M351T, and Y253F.

Results and Conclusion:

TKD mutation study was done on 83 patients. Of these 44 (53%) were positive for one or more mutations. On analyzing specific mutations, E255K was the commonest mutation seen in 24 (29%) cases, followed by T315I in 23(28%) cases. Y253F mutation was not seen in the present study sample. In the present cohort of 83 patients, 29 (35%) cases were positive for single mutation, 12 (14%) had two mutations and 3 (4%) had three mutations.

Published: November 2021

Background:

Peroral endoscopic myotomy (POEM) is an established modality of treatment for achalasia cardia. Considerable variations exist in the technique of POEM with respect to the length and orientation of the myotomy. In this systematic review and meta-analysis, we compared the outcomes of short versus long myotomy during POEM.

Methods:

We searched multiple databases from January 2010 to March 2021 to identify studies reporting on POEM. We selected studies that reported on comparative outcomes of POEM using short versus long myotomy. We performed a comparative analysis of clinical success, procedural duration, gastroesophageal reflux disease (GERD), and adverse events with short and long myotomy in POEM by meta-analysis.

Results:

A total of 521 patients from five studies in which 241 patients were treated with short and 280 patients with long myotomy approaches were analyzed. The pooled rate for clinical success gave an odds ratio (OR) of 1.27 (95% confidence interval [CI] 0.50–3.26; I2 = 0; P = 0.62); for hospital stay OR 0.22 (95% CI − 0.03 to 0.46; I2 = 0; P = 0.08); for GERD by esophagogastroduodenoscopy (EGD) OR 0.58 (95% CI 0.31–1.07; I2 = 0; P = 0.08), and for adverse events OR 0.67 (95% CI 0.29–1.53; I2 = 51; P = 0.34). Abnormal esophageal acid exposure was less frequent with OR 0.45 (95% CI 0.22–0.90; P = 0.02; I2 = 0) and the procedure duration was significantly shorter in the short myotomy group with OR − 0.76 (95% CI − 1.00 to − 0.52; I2 = 43; P =0.001).

Conclusion:

Short myotomy and long myotomy in POEM seem comparable with each other in terms of clinical success and adverse events. Short myotomy is associated with significantly shorter procedural duration and possibly reduced esophageal acid exposure compared with long myotomy.

Purpose Angiogenesis is a crucial phenomenon in the development and progression of breast cancer (BC), but the clinical significance of angiogenesis-related proteins in metastatic BC remains unknown. This study investigates the prognostic value of vascular endothelial growth factor receptors 1, 2, 3 (VEGFR1, VEGFR2, VEGFR3) as well as vascular endothelial growth factors A and C (VEGFA and VEGFC) in metastatic BC patients treated with trastuzumab-based regimens.Materials and Methods Two hundred female patients were included. Protein and mRNA expression of the studied angiogenesis-related factors were evaluated by immunohistochemistry and quantitative polymerase chain reaction, respectively.Results High expression of VEGFA, VEGFC, VEGFR1, VEGFR2, and VEGFR3 in the tumor cells was observed in 43.5%, 24.2%, 36%, 29.5%, and 43%, respectively. Stromal elements expressed high levels of VEGFA, VEGFC, VEGFR1, VEGFR2, and VEGFR3 in 78.9%, 93.3%, 90.7%, 90.2%, and 74.8% of tumors with available data. High tumor cell expression of VEGFR1 was a favorable prognosticator for survival among patients with human epidermal growth factor receptor 2 (HER2)–positive tumors (hazard ratio [HR], 0.55; p=0.013). A trend towards longer progression-free survival was detected univariately for patients with HER2-negative tumors and high expression of VEGFR2 (HR, 0.60; p=0.059).Conclusion VEGFR1 and VEGFR2 seem to have significant prognostic value in BC patients with metastatic disease treated with trastuzumab-based regimens.

Older adults who go through a situation of family abandonment tend to suffer from sadness, loneliness or even worse depression, which leads to various situations in their daily lives. Most older adults suffer from type 2 diabetes mellitus, living with this pathology requires multiple care and interventions by the person himself and with the support of the rest of the family, in order to provide adequate routine care for the patient; That is why when there is family neglect, patients lose interest in taking care of themselves and tend to fall into a routine. In the present study, the self-care deficit in older adults was identified. It is a study of non-experimental quantitative design, cross-sectional, correlational, since it is carried out at a specific time and the variables do not have a control. The population is older adults with diabetes pathology, inhabitants of a day house in the state of Hidalgo, Mexico. The sample consisted of 30 people by availability. A survey was conducted among the elderly, only patients living with diabetes pathology to make an analysis of the care performed. As results, it was obtained that approximately 3% of older adults in a home for the elderly in Pachuca de Soto, Hidalgo, carry out proper self-care in their daily activities. A third of older adults have a self-care deficit, it is associated with different situations, starting with non-adherence to treatment and unhealthy habits. The majority of older adults have self-care deficits and therefore tend to be complicated by the pathologies they suffer, it is likely that their blood glucose levels are elevated, as well as the appearance of xerosis on the skin on the feet and hands; To correct this behavior, it is suggested to carry out workshops to teach the correct way to carry out adequate care, as well as to encourage adherence to treatments, carry out a good diet and exercise regularly in order to improve their health and extend life expectancy.

Authors: Genuino Rowena Natividad F. , Tiangco Beatrice J. , Besa John Jefferson V. , Bayona Howell Henrian G.
Published: November 2021

Background. Pooled testing has been implemented on a limited scale, mainly for screening and surveillance in populations with a low prevalence of COVID-19 to save on limited resources.

Objective. To determine the diagnostic accuracy of pooled compared with individual RT-PCR testing for SARS-CoV-2 in individuals suspected of COVID-19.

Methods. We searched websites of living CPGs on COVID-19 (Australian COVID-19, COVID NMA, CEBM Oxford), Philippine DOH HTA, databases (PubMed, CENTRAL, medRXIV/bioRXIV), and Clinicaltrials.gov for studies that used pooled testing on individuals suspected of COVID-19. When appropriate, we pooled data for sensitivity and specificity and obtained the range and median of other data, such as positive predictive value and resource savings. We did a priori subgroup analysis for pool size, presence or absence of symptoms and use case, type of specimen, cutoff for positivity, type of kit, and post hoc subgroup analysis for method of pooling and timing of processing.

Results. We included 21 studies: 6 diagnostic accuracy studies, and 15 clinical validation studies. Studies had varying populations, index test kit and performance characteristics, positivity rate (0.02 to 15%), and pool size (5 to 16). There was moderate pooled sensitivity, 81% (95% CI 72, 88; I2=73.6%; 6 studies, 776 pools) and high pooled specificity, 99% (95% CI, 98 to 100; I2=1.84%; 5 studies, 666 pools). Positive predictive value based on 21 studies ranged from 67% to 100%. Resource savings in the number of test kits used ranged from 49 to 89%. Identified harms of pooled testing were delayed turnaround time for positive samples and laboratory errors.

Conclusion. There is moderate sensitivity and high specificity with pooled testing for the screening of individuals with suspected COVID-19. We recommend further studies to validate the utility based on community prevalence and other test variables.

Authors: Саванов И.С. , Дмитриенко Е.С.
Published: November 2021

Ранее по данным наблюдений с космическим телескопом “Kepler” нами было показано, что по своим параметрам KIC 7739728 близка к звездам типа FK Com и может рассматриваться, как потенциальный кандидат для включения в число объектов этого типа. В настоящей работе мы провели анализ всех имеющихся для KIC 7739728 данных в архиве миссии TESS (14 и 26 сектора наблюдений). Показано, что кривая блеска этой звезды ярко проявляет свойства регулярной вращательной модуляции и что в период времени между 14 и 26 секторами произошло явление переключения положений долгот активных областей на поверхности звезды (флип-флоп). Рассматриваются аргументы в пользу возможной принадлежности KIC 7739728 к объектам типа FK Com.

Using the observations with the Kepler space telescope we found that parameters of KIC 7739728 are close to that ones of the FK Com type stars and that the object can be considered as a potential candidate for inclusion in the number of objects of this type. In this paper we analysed all available data for KIC 7739728 in the TESS mission archive (14 and 26 sectors). It is shown that the light curve of this star clearly exhibits the properties of regular rotational modulation and that in the time interval between 14 and 26 sectors the phenomenon of switching the positions of the longitudes of the active regions on the surface of the star (flip-flop) occurred. The arguments in favour of the possible relation of KIC 7739728 to objects of the FK Com type are considered.

Authors: Eslayeh Asmaa H. , Omar Rokiah , Md Fadzil Norliza
Published: November 2021

Background: Refractive amblyopia is the most common cause of amblyopia in the Gaza Strip. However, the pattern of this condition has not yet been studied in this region. This study aimed to determine the pattern of refractive amblyopia in Gazan children aged 4?12 years.Methods: This was a hospital-based cross-sectional study using a purposive sampling method. Children aged 4?12 years who attended the Children’s Unit at Gaza Ophthalmic Hospital, Gaza Strip, Palestine from September 2019 to July 2020, were examined. A comprehensive eye test was conducted for all participants. Those who failed the eye examinations and were diagnosed with refractive amblyopia were included in the study. Demographic data and amblyopic refractive error patterns were analyzed accordingly.Results: Of the 107 children, 72.9% were newly diagnosed with refractive amblyopia. The mean ± standard deviation (SD) of age of the children who participated was 7.85 ± 1.55 years. Approximately two-thirds of the patients were female (57.9%). Unilateral amblyopia was predominant in 60.7% of the cases. Moderate amblyopia was common (81.9%). A total of 149 amblyopic eyes were examined in total, with a mean ± SD (range) of best-corrected distance visual acuity and spherical equivalent of 0.45 ± 0.19 (0.2 to 1.3) logarithm of the minimum angle of resolution and + 0.76 ± 4.51 diopters (- 10.25 to + 11.50). Astigmatism was the most common amblyogenic factor (53.7%) among children with amblyopia.Conclusions: The frequency of refractive amblyopia was 72.9%, and meridional amblyopia accounted for the highest percentage. Girls were more commonly affected than boys. The majority were in the 7-year-old age group. Most cases were unilateral with moderate refractive amblyopia. Our study yields insights into the patterns of refractive amblyopia among children in the Gaza Strip.

СТИГМАТИЗАЦИЯ, САМОСТИГМАТИЗАЦИЯ И ДЕСТИГМАТИЗАЦИЯ НА ПРИМЕРЕ МИГРАНТОВ С БЫВШИХ РЕСПУБЛИК СССР В ПОЛЬШЕ
Authors: Митяй Оксана
Published: November 2021

В данной публикации представлены результаты исследований проблем социальной стигматизации мигрантов со стран бывшего СССР (украинцев, белорусов, русских) в Польше. Анализ литературных источников по проблеме стигматизации показал, что она является актуальной для самых разных социальных категорий. Большую роль здесь играет самостигматизация: осознание стереотипа, согласие с ним и применение его к себе. В результате чего снижается самооценка и самоэффективность и как следствие, люди отказываются от использования возможностей, которые являются основополагающими для достижения жизненных целей. Но часто реакция на стигму вызывает желание расширить свои возможности, появляется уверенность в том, что стереотипы не помешают достижению поставленных целей и здесь возникает процессс дестигматизации, то есть восстановление членами стигматизированных групп своих гражданских прав, утраченных в связи с самостигматизацией и внешней стигматизацией.

FATIGUE FAILURE AS A COMPLEX OF RELAXATION PROCESSES OCCURRED AT THE VERTICES OF THE STRESS RISERS
Authors: Volosevish P. , Mordyuk B.
Published: November 2021

This paper considers the stress-dependent fatigue life of polycrystalline materials and their fatigue failure as a result of the relaxation processes that occurred on the stress risers of various scales: macroscopic stress risers of technological nature (pores, cracks, surface roughness, etc.), and microscopic stress risers at the grain/subgrain boundaries and/or second phase particles. Participation of the relaxation mechanisms plastic (vacancies and dislocation activities, grain boundary sliding) and brittle (cracks) nature in the process of the ‘fish eye’ fatigue crack formation is also addressed. The model described the parabolic dependencies of the densities of elementary carriers of plastic and brittle relaxations on the load change rate (i.e., on the growth rate of the stresses concentrated at the vertices of the stress risers) correlates well to the fatigue life data observed for the surface-modified metallic materials.

Published: November 2021

El presente artículo de reflexión propone como finalidad plantear los desafíos de la antropología forense y social en materia de recuperación e identificación humana y el resarcimiento de derechos en un escenario de posconflicto en Colombia. En primer lugar, se hace una descripción importante de este tópico en un contexto de Derechos humanos, en segundo lugar, un análisis de las teorías que tienen una visión social y cultural en el marco de la justicia transicional y el aporte jurídico, finalmente, se presenta el aporte de la antropología forense y social a las familiares víctimas del conflicto interno ya en su etapa de posconflicto. Se concluye que, en un proceso integral de justicia, verdad, reparación y no repetición, no solo son importantes la recuperación e identificación de las víctimas, sino también, el descubrimiento del modus operandi de los victimarios, y servir testimonialmente en los procesos jurídicos de modo que, se aporte a las víctimas y a la memoria histórica.

Seasonal ecosystem vulnerability to climatic anomalies in the Mediterranean
Authors: Vogel Johannes , Paton Eva , Aich Valentin
Published: November 2021

Abstract. Mediterranean ecosystems are particularly vulnerable to climate change and the associated increase in climate anomalies.
This study investigates extreme ecosystem responses evoked by climatic drivers in the Mediterranean Basin for the time span 1999–2019 with a specific focus on seasonal variations as the seasonal timing of climatic anomalies is considered essential for impact and vulnerability assessment.
A bivariate vulnerability analysis is performed for each month of the year to quantify which combinations of the drivers temperature (obtained from ERA5-Land) and soil moisture (obtained from ESA CCI and ERA5-Land) lead to extreme reductions in ecosystem productivity using the fraction of absorbed photosynthetically active radiation (FAPAR; obtained from the Copernicus Global Land Service) as a proxy. The bivariate analysis clearly showed that, in many cases, it is not just one but a combination of both drivers that causes ecosystem vulnerability.
The overall pattern shows that Mediterranean ecosystems are prone to three soil moisture regimes during the yearly cycle: they are vulnerable to hot and dry conditions from May to July, to cold and dry conditions from August to October, and to cold conditions from November to April, illustrating the shift from a soil-moisture-limited regime in summer to an energy-limited regime in winter.
In late spring, a month with significant vulnerability to hot conditions only often precedes the next stage of vulnerability to both hot and dry conditions, suggesting that high temperatures lead to critically low soil moisture levels with a certain time lag.
In the eastern Mediterranean, the period of vulnerability to hot and dry conditions within the year is much longer than in the western Mediterranean.
Our results show that it is crucial to account for both spatial and temporal variability to adequately assess ecosystem vulnerability.
The seasonal vulnerability approach presented in this study helps to provide detailed insights regarding the specific phenological stage of the year in which ecosystem vulnerability to a certain climatic condition occurs.
Detention Centers als vernetzte Räume des Einschlusses? Eine gouvernementalitätstheoretische Perspektiverweiterung am Beispiel Lesvos
Authors: Breuckmann Tobias
Published: November 2021

Abstract. The article examines the strategic role of detention in the Reception and
Identification Center on Lesvos, Greece. Basing on works on detention in
carceral geography, I will additionally use the theoretical framework of
governmentality. It becomes clear that the detention center on Lesvos serves
as a spatial configuration of localization and circulation of asylum seekers
framed as belonging to countries with low recognition rate. This is mainly
enhanced through confinement, forced or controlled mobilisation as well as
the control of flows of assistance and information through containment. In
conclusion, certain modes of circulation and mobilization through enclosure
can be identified through combination and mutual fertilisation of carceral
geography and governmentality.
Validating a Tailored Disaster Risk Assessment Methodology: Drought Risk Assessment in Local PNG Regions

Published: November 2021

Abstract. Climate change is increasing the frequency and intensity of natural hazards, causing adverse impacts on vulnerable communities. Pacific Small Island Developing States (SIDS) are of particular concern, requiring resilient disaster risk management consisting of two key elements: proactivity and suitability. User-centred Integrated Early Warning Systems (I-EWSs) can inform resilient risk management. However, an EWS is only effectively integrated when all components are functioning adequately. In Pacific SIDS, the risk knowledge component of an I-EWS is underexplored. Risk knowledge is improved through efficient risk assessment. A case study assessing drought risk in PNG provinces was conducted to demonstrate the development and validate the application of a tailored risk assessment methodology. Hazard, vulnerability, and exposure indicators appropriate for monitoring drought in PNG provinces were selected. Risk indices for past years (2014–2020) were calculated and mapped in Geographic Information Systems (GIS). Risk assessment results were validated with a literature investigation of sources presenting information on previous droughts in PNG. The risk assessment indicated a strong drought event in 2015–2016, and a moderate event in 2019–2020. The literature corroborated this, confirming the validity of the risk assessment methodology. The methodology and results can be used to inform improved disaster risk management in PNG, by advising decision-makers of their risk and policymakers on which provinces are of priority for resource allocation. The methodology can also be used to enhance the risk knowledge component of a user-centred I-EWS and guide the implementation of such a system for drought in PNG and other Pacific SIDS.

Published: November 2021

Introduction: Inappropriate child feeding practices is a major contributor of undernutrition and childhood mortalityin India. The optimal infant and young child feeding (IYCF) practices rank among the most effective intervention to improve child health and nutritional status. Objective: 1. To study the IYCF practices among mothers residing in urban slums of Agartala. 2. To study the factors associated with exclusive breast feeding and Minimum acceptable dietary intake. Method: This was a community based Cross-sectional study conducted among 180 mothers of children <24 months, residing in Urban slums of Agartala. Multistage simple random sampling procedure was adopted, and ‘WHO standard questionnaire for IYCF practices’ was used to assess the IYCF practices.Results: The study showed that the prevalence of exclusive breast feeding under 6 months was 67.39% and 91.70% mothers were continuing breast feeding at 2 years of age. Regarding complementary feeding practices, 67.20%, 73.90% and 58.95% children were having food with minimum dietary diversity, minimum meal frequency andminimum acceptable dietary (MAD) intake respectively. Early initiation of breast feeding was significantly associated with breast feeding practices (p value-0.00). Whereas, increasing age (p value-0.00),higher birth order (p value-0.03) and type of family (p value-0.01) had significant association with MAD intake. Conclusion: Study reveals suboptimal IYCF practices in the slums. There is urgent need to strengthen the on-going programs on IYCF practices targeting children with younger age and higher birth order.

Mechanical Characteristic and Water Absorption Property of Bio Composite from Sago Starch and Jute Fiber (Boehmeria Nivea) as the filler
Authors: Dewi Rozanna , Oktaviani Oktaviani , Ginting Zainuddin , Sylvia Novi
Published: November 2021

Environmentally friendly plastics can be degraded biologically in an anaerobic environment. This plastic is synthesized from starch such as sago starch which is available in abundance. In the form of bioplastics, its mechanical properties are still not compared to conventional plastics derived from crude oil, so its application is limited. The incorporation of filler material increases its mechanical properties, one of the selected fillers is hemp fiber as used in this study. Thermoplastic starch from sago with flax fiber as a filler and the addition of Polypropylene to improve mechanical properties with a certain composition to maintain its natural biodegradability. The mechanical properties analyzed were tensile strength, elongation and modulus of elasticity. Water absorption tests were also carried out to observe the water resistance properties. The results of the tensile strength test showed that the best tensile strength value of 9.32 Mpa was obtained at the addition of 35% fiber with a TPS: PP ratio of 1:1.5. The same conditions were obtained for the percent elongation with the results of 10.16% and the modulus of elasticity was 91.73 Mpa. Water absorption showed that 55% filler gave the lowest water     absorption, namely 4.41% at a ratio of TPS: PP 1:0.5. The addition of fiber filler into the bio-composite affects the tensile strength,    elongation and modulus of elasticity, the higher the volume of filler entering the bio-composite, the lower the value of tensile strength, elongation and modulus of elasticity, or vice versa. The ratio of addition of polypropylene matrix is also influential, the higher the ratio contributes to the tensile strength, elongation and higher modulus of elasticity. High water absorption capacity will reduce the performance of biocomposite, so the lower the water absorption ability, the better the quality of the biocomposite product and the wider its application
A ‘Version’ in the languages of different systems
Authors: Charkviani Nunu , Rusadze Irma , Kipiani Sopo
Published: November 2021

The article deals with one of the language phenomena so called ‘version’ in the languages of different systems. A version has been supposed to be a morphological category of a verb in Georgian for a long time. Its function to show verb action possession between the parts of the sentence is conveyed in English through analytical forms with the help of additional words and through verb prefixes (synthetically) in Georgian. So, the work demonstrates version functioning in both languages in different ways through the examples from fiction.Besides, the article discusses a debatable issue whether this language phenomenon represents a verb grammatical category or it is simply an action direction. This supposition comes from the fact that the very prefixes for version in Georgian and the very additional words in English used to express this phenomenon cause some confusion in language learners and even in language explorers to consider version a morphological category. Also, in the bases of opinions of Georgian linguistics ‘version’ might be hardly qualified as a grammatical category.
