EARLY STIMULATION INFLUENCES THE DEVELOPMENT OF A CHILD BETWEEN 0 AND 3 YEARS OF AGE, IN A VULNERABLE SOCIAL STRUCTURE
Authors: Salum Tomé José Manuel
Published: January 2022

SUMMARY: The presence of Special Educational Needs (SEN) in students inserted in the school system
has been a theme in which many areas of knowledge have tried to investigate. The psychological theory
suggests that newborns begin their development starting from a similar basis, and that the different types of stimulation and the
brain's ability to adapt to different episodes can be a determining factor in the development of skills and abilities. It is also
considered that the family environment is the closest circle and with which the infants have the most contact in this period,
therefore, the impact that the stimulation delivered by these people has on the adequate development of the cognitive,
psychomotor and of a child's language, could be related to the presence of SEN and its subsequent consequences in the
pedagogical and psychopedagogical areas when they enter the school system.
The present work aims to identify stimulation styles to favor the integral development of children up to three years of age.

Authors: Harshima Harshima , S Hogade Ashok
Published: January 2022

Background: Psoriasis is a common, immunologically mediated, inammatory disease characterized
by skin inammation, epidermal hyperplasia, and increased risk of painful and destructive arthritis and
cardiovascular morbidity and psychosocial challenges. Recent studies have shown higher prevalence of vitamin D deciency
in patients with psoriasis than in control groups. It has been recently discovered that, vitamin D has role in modulation of Type 1
helper T cell (Th1) pathway. Thus low levels of vitamin D is believed to have an important implication in pathogenesis of
psoriasis. Aims and objectives: To determine the 25-hydroxyvitamin D status of patients with chronic plaque psoriasis in
comparison with age and sex matched controls. Materials and Methods: Thirty consecutive consenting patients with chronic
plaque psoriasis and 30 age and sex matched controls with minor dermatological diseases were recruited in this study.
Results: The age of the subjects ranged from 18yrs to 62yrs. The number of males was more than females. The overall
prevalence of vitamin D in the study sample was 75%. Eighty percent cases and 70% controls had deciency of vitamin D. This
study reveals that, the mean vitamin D was 16.23ng/do in case group and 19.29ng/dl in control group. The mean vitamin D was
less in the cases as compare to controls, but it was not statistical signicant. Conclusion: Due to high overall prevalence of
vitamin D deciency in India, many of the cases and controls had shown deciency. Not statistically signicant difference could
be established between cases and controls with respect to serum vitamin D levels.

Authors: YV Abhijith , Thapar R K , Rao Akhilesh , R K Gupta , Kumar Singh Rajesh , A Arun
Published: January 2022

INTRODUCTION:Necrotizing enterocolitis (NEC) is the most serious and common gastrointestinal
emergency occurring among the neonates. NEC affects 1–5% of all neonates & approximately 7% of
preterm infants <1500 grams. The incidence among premature neonates weighing less than 1500 grams is approximately 12%
with mortality of 30-35%. NEC is an acute inammatory injury involving the distal small and often proximal large intestine.
Segmental coagulative necrosis of the mucosa with focal haemorrhage can be seen histopathologically. The radiological
features appear late in the necrotizing enterocolitis. The delay in diagnosis will lead to increased mortality and morbidity. The
features of NEC can be detected early in the ultrasonography of the abdomen.
AIM: The primary objective as Abdominal Ultrasonography (AUS) being investigation of choice in the early diagnosis of NEC
and secondary objective of evaluating the morphological features seen in ultrasound and correlation with clinical, X-ray
ndings.
MATERIAL AND METHODS: This is a prospective study done from March 2016 to August 2017 at a Tertiary care referral centre.
The sample size was calculated as 15, using Snedecor and Cochran formula. All the neonates which fullled the inclusion
criteria were included in the study. The neonates with congenital anomalies and hemodynamic instability were excluded. The
outcome was based on the AUS ndings. Statistical analysis of data done using the Statistical Package for Social Sciences
(SPSS), version 24.0.
RESULTS: The neonates included in the study were from 27 weeks to 38 weeks of gestation and mean age of presentation was
4.80±3.50 days, with the male female ratio 2.7:1. 02 (13%) neonates were of 27 weeks gestation, 01 (6.6%) was of 28 weeks of
gestation, 02 (13%) were of 29 weeks of gestation, 02 (13%) were of 30 weeks of gestation, 04 (26%) were of 32 weeks of gestation,
01 (6.6%) was of 33 weeks of gestation and 02 (13%) were of 37 weeks of gestation. The mean birth weight±SD (range) in the
study was 1447±601 grams. The neonates presented with features of feed intolerance 15 (100%), abdominal distension 8
(53.3%), lethargy 3 (20%). AUS detected abnormal ndings in 10 neonates, in whom there were no radiological abnormalities.
There was statistically signicant association between the altered temperature and ultrasound ndings (p value -0.014).
CONCLUSIONS: Abdominal ultrasonography is more sensitive to detect NEC at early stage.

Authors: Varshney Jahnvi , Agarwal Shivani , Ajmani Sangita N
Published: January 2022

Purpose of the study- To study the efcacy of mifepristone followed by misoprostol over misoprostol alone
in early pregnancy failure in terms of complete evacuation of uterus.
METHODS: In a randomized comparative study at the Department of Obstetrics and Gynaecology of Kasturba Hospital, 100
women with early pregnancy failure and gestational age ≤12 weeks between January 2017 and December 2017 were recruited.
Of these, 50 women were given a single oral dose of mifepristone (200 mg) followed by 800 mcg misoprostol vaginally (if
required) after 24 hours and the other 50 women were treated with 800 mcg misoprostol vaginally alone.
RESULTS: Complete evacuation of uterus was achieved in 96% women treated with a sequential combination of mifepristone
and misoprostol versus 84% women treated with misoprostol alone. The difference in the rate of complete expulsion was 12% (p
<0.05, 95% CI). Also, pre-treatment with mifepristone resulted in statistically signicant reduction in induction to abortion
interval (2.40 ± 1.774 vs 3.30 ± 1.951 hr), amount of bleeding (402.2 ± 111.84 vs 535.0 ± 114.84 ml) and duration of bleeding
(10.7 ± 2.30 vs 12.4 ± 3.38 days).
CONCLUSION Medical treatment of early pregnancy failure with a sequential combination of mifepristone and misoprostol
was more effective than misoprostol alone. Hence, women with early pregnancy failure may be offered mifepristone pretreatment before misoprostol to increase the chance of successful management, while reducing the need for surgery.

This finding is supported by the average score of the experimental group (mean = 81.0345) which is higher than the control group (mean = 76.9730) so it can be concluded that the hypothetical-deductive learning cycle model has a significant effect on students' mathematics learning outcomes.
Teresa of Avila and Jonathan Edwards on Prayer and Spirituality
Authors: Liem Yoe Gie Jonathan
Published: January 2022

Contemplative prayer has been a major source of contention in evangelical spirituality. Contemplative prayer is frequently mentioned as one apparent spiritual activity that is foreign to the scripture and Christian worldview and more resembling the New Age Movement and pantheistic Eastern religion by people who are skeptical of the mystical Christian tradition. This article will examine Teresa of Avila’s thought on mystical prayer, which is sometimes misinterpreted as a notion incompatible with evangelical theology of prayer. Hence, Teresa’s ideas of mystical prayer will be examined and compared with Jonathan Edwards’ concepts of prayer, which is considered to reflect evangelical theology of prayer. The comparison suggests that the contemplative, mystical prayer of Teresa is compatible with evangelical theology of prayer in its progress and purpose. Teresa and Edwards both understood prayer as an experience and progress that leads to the complete union with God, mediated by Christ and his words in scripture. This spiritual union with God will transform the devoted one with tremendous passion and strength to love and help others in their struggle and suffering. This study of Teresa’s thought of mystical prayer is expected to reinvigorate evangelical theology and praxis of prayer by learning from the rich spirituality of the Christian mystical tradition.
Acoustic Features Based Emotional Speech Signal Categorization by Advanced Linear Discriminator Analysis
Authors: Shakya Subarna
Published: January 2022

Personal computer-based data collection and analysis systems may now be more resilient due to the recent advances in digital signal processing technology. The signal processing approach known as Speaker Recognition, uses the specific information contained in voice waves to automatically identify the speaker. For a single source, this study examines systems that can recognize a wide range of emotional states in speech. Since it offers insight into human brain states, it's a hot issue in the development during the interface between human and computer arrangement for speech processing. Mostly, it is necessary to recognize the emotional state of people in the arrangement. This research analyses an effort to discern various emotional stages such as anger, joy, neutral, fear and sadness by classification methods. The acoustic feature, a measure of unpredictability, is used in conjunction with a non-linear signal quantification approach to identify emotions. The unpredictability of all the emotional signals is included in a feature vector constructed from the calculated entropy measurements. In the next step, the acoustic features through speech signal are used for the training in the proposed neural network that are given to linear discriminator analysis approach for further greater classification with acoustic feature extraction. Besides, this research article compares the proposed work with various modern classifiers such as K- nearest neighbor, support vector machine and linear discriminator approach. Moreover, this proposed algorithm is based on acoustic features in Linear Discriminant Analysis (LDA) with acoustic feature extraction machine algorithm. The great advantage of this proposed algorithm is that it separates negative and positive features of emotions and provides good results during classification. According to the results from efficient cross-validation in the proposed framework, accessible sample of dataset of Emotional Speech, a single-source LDA classifier can recognize emotions in speech signals with above 90 percent of accuracy for various emotional stages.
