MATHEMATICAL APPARATUS TO ANALYZE INTERFERENCE-SUPPRESSING STRIP DEVICES WITH ASYMMETRIC STRUCTURE
Authors:   Tomsk State University of Control Systems and Radioelectronics  634050, Tomsk, Lenina str., 40, Surovtsev R.S.
Published: February 2023

A mathematical apparatus that is used to analyze protective devices based on a meander line (ML) turn. The apparatus takes into account the effect of asymmetry of cross-section on the propagation of pulse signal in a turn The developed mathematical apparatus includes: a model for calculating radiated emissions from a turn with an arbitrary cross-section; an analytical model for calculating the time response at the turn output; models for obtaining conditions that ensure the complete ultrashort pulse (USP) decomposition in multistage devices The proposed apparatus was evaluated on the example of structures with broad-side and side coupling (by the comparison with the results of computer simulation). As a result of comparison of frequency dependences of the maximum electric field strengths obtained using the model and numerically were produced ambiguous results. For the ML turn with broad-side coupling, the dependences were found to be in good agreement qualitatively in the frequency range up to 2.5 GHz. However, they can differ significantly in terms of quantity. More specifically, at some frequencies, there are pronounced maxima of the frequency dependences obtained numerically. For the turn with side coupling, the amplitudes of the maximum field strengths calculated by the model were found to be higher in the entire frequency range (with the exception of several maxima) than those calculated numerically. The constructed directional diagrams of the turn confirm the quantitative discrepancies. Meanwhile, the analysis of the obtained results allows us to claim that the real field strengths will be lower than those calculated by the model, so the model is applicable for preliminary estimates. As a result of evaluation of the analytical model for calculating the time response at the turn output revealed a complete coincidence of the time responses obtained on the basis of the model and numerically. Finally, the models to obtain the conditions for the complete pulse decomposition were evaluated on the example of 3-stage devices. The results demonstrated that the developed models were correct. The case was also considered when the conditions obtained using the models are not met, which leads to an increase in the signal amplitudes at the output of the devices. Thus, the entire presented mathematical apparatus can be used to analyze protective devices based on an ML turn with an asymmetric cross-section.

Published: February 2023

This study aims to examine the distance learning practices carried out at the primary education level during the COVID-19 pandemic from students’ and their parents' perspectives. The study was conducted with 76 primary school students at different grade levels, including their parents (76), in the state schools of Giresun city in the spring semester of the 2019-2020 academic year. The study was based on the case study method, one of the qualitative research designs. An information collection form with open-ended questions was used as a data collection tool. The data obtained from the information collection form were analyzed by the content analysis method. The findings have revealed that the distance learning system has a flexible structure and is accessible from any place, but there are difficulties accessing the system due to connection problems. These systems facilitate the teaching process, affecting learning positively. The findings also showed that distance learning systems are not favored by students who long for friends and teachers during the learning process performed on these systems. Unlike face-to-face training, disciplinary and supervision problems in distance learning are also noteworthy. The authors finally suggest that the distance learning and management process should be performed in a restrained manner to ensure the process to be run effectively and efficiently. Keywords: distance learning, COVID-19, K-12

Published: February 2023

Teachers’ perceptions of long-term career success are largely related to the levels of support they receive early on in their careers. This study on teacher retention and the factors that influence teacher choice to remain in the field after the first five years of employment, examined three schools of varying demographics and socioeconomic status in a large public school district in Central Florida. Participants interviewed were in the first three to five years of their teaching career. Information derived from each interview was used to determine trends and factors that influence teacher retention and attrition. The main finding was that when teachers feel supported through professional development, time for collaboration with colleagues, and autonomy, they are more likely to remain in the teaching profession. Keywords: teacher retention, elementary schools, teacher recruitment, principal leadership, organizational systems in schools

Charter Schools and the Segregation of Students by Income
Authors: Dalane Kari , Marcotte Dave E.
Published: February 2023

The share of students attending charter schools has been rising. There is evidence that charter school growth has increased socioeconomic segregation of students between schools. In this paper, we assess whether charter school growth affects how students are organized within nearby traditional public schools (TPS). We use administrative data from North Carolina to estimate the impact of charter school openings on segregation by income within nearby TPS. Our models exploit variation in the presence and location of charter schools over time between 2007 and 2014 for students in Grades 3 to 8. We find limited evidence that the segregation of students by income at the classroom level increases when charters open nearby. We find some evidence of increasing segregation in third grade and fourth grade math and third grade ELA classrooms at TPS within 2 miles of new charters in large urban districts schools. Our results vary somewhat depending on how we control for underlying trends and measure segregation. We find no effect of charter school growth on income segregation in higher grades.
Resource for Self-Determination or Perpetuation of Linguistic Imposition: Effects of English Learner Classification Among Alaska Native Students*
Authors: Umansky Ilana M. , Vazquez Cano Manuel , Porter Lorna M.
Published: February 2023

Federal law defines eligibility for English learner (EL) classification differently for Indigenous students compared with non-Indigenous students. To be EL-eligible, non-Indigenous students are required to have a non-English primary language. Indigenous students, by contrast, can be English-dominant or English monolingual. A critical question, therefore, is how EL classification impacts Indigenous students’ educational outcomes. This study explores this question for Alaska Native students, drawing on data from five Alaska school districts. Using a regression discontinuity design, we find preliminary evidence that among students who score near the EL classification threshold in kindergarten, EL classification has a large negative impact on Alaska Native students’ academic outcomes in the third and fourth grades. Negative impacts are not found for non–Alaska Native students.
Quantifying the Systematic Bias in the Accessibility and Inaccessibility of Web Scraping Content from URL-Logged Web-Browsing Digital Trace Data
Authors: Dahlke Ross , Kumar Deepak , Durumeric Zakir , Hancock Jeffrey
Published: February 2023

Social scientists and computer scientists are increasingly using observational digital trace data and analyzing these data post hoc to understand the content people are exposed to online. However, these content collection efforts may be systematically biased when the entirety of the data cannot be captured retroactively. We call this unstated assumption the problematic assumption of persistence. To examine the extent to which this assumption may exist, we examine over 21 million URL-logged web browser visits from 1,515 participants over four months and record the degree to which hard news and misinformation URLs individuals visited were persistent, inaccessible, or ephemeral. While we find that the URLs collected are largely persistent, we find there are systematic biases in which URLs are ephemeral and inaccessible. For example, conservative misinformation URLs are more likely to be ephemeral than other types of misinformation. To standardize the reporting and understanding of the problematic assumption of persistence, we offer a set of metrics, PersistenceRate, InaccessibilityRate, EphemeralityRate (PIE metrics), that future research should report when using digital trace and web scraping data.

Published: February 2023

Introduction: Pacific adolescents in New Zealand (NZ) are two to three times more likely than NZ Europeans to report suicide attempts and have higher rates of suicidal plans. Suicidal thoughts and behaviours, termed suicidality in this study, result from a complex dynamic interplay of factors which emerging methodologies like network analysis aim to capture. Methods: This study used network analysis to model the relationships between suicidality, self-harm, and individual depression symptoms cross-sectionally, whilst controlling for a multi-dimensional set of variables relevant to suicidality. A series of network models were fitted to data from a community sample of New Zealand-born Pacific adolescents (n=550; 51% male; Mean age (SD) = 17 (0.35)). Results: Self-harm and the symptom measuring pessimism were most strongly related to suicidality, followed by symptoms related to having a negative self-image about looks and sadness. Non-symptom risk factors for self-harm and suicidality differed markedly.Conclusions: Depression symptoms varied widely in terms of their contribution to suicidality. These results highlight the valuable information gained from analysing depression at the symptom-item level. The analysis suggests reducing the sources of pessimism and building self-esteem presented as potential targets for alleviating suicidality amongst Pacific adolescents in New Zealand.
Sexuality of Jung Bahadur Rana
Authors: K C Tej Bahadur
Published: February 2023

The article focused on Jung Bahadur Rana, the Prime Minister of a period in the history of modern Nepal and his activities. Many activities of Janga Bahadur have become the subject of history. Some of Jung Bahadur's activities made him immortal, while others made him notorious. Among his activities, the main activity is his sexual attraction to heterosexuals. The presented article focuses on the theme of sexual activity of this Jung Bahadur. In particular, the purpose of this article is to expose what kind of sexual activities Jung Bahadur did during his lifetime. Jung Bahadur's bravery and courage earned him much respect, but his attachment to women had a negative effect on it. Although it is said that Jung Bahadur had infinite courage and determination, he could not control his sexual weakness. Jung Bahadur Rana's uncontrollable sexual activities became the subject of broadcast even in foreign media. Some of his sexual activities were outstanding. They used to bring many beautiful women in the palace and also appointed employees for their movement. Among his means of entertainment, sex was the most preferred subject. He wanted to show himself to be good at sex. It is the law of nature that sexual desire and sexual activity decrease as people get older due to increasing age, busyness of politics and other reasons. Unable to understand this matter, Junga Bahadur felt that he was weak in his sexual addiction even though he was an old man and started taking opium. The purpose of this article is to investigate the sexual desire of Junga Bahadur Rana by exposing the fact that from time to time he used to be self-condemned and sometimes he used to be very depressed.
Paradigm Shift in Social Science Research: A General Perspective
Authors: Aryal Vijay
Published: February 2023

This paper explores the paradigm shift in social science research from positivism to the contemporary approach of indigenous research paradigms. The paper is based on relevant literature on paradigm shift reviewed. It begins with a discussion of Kuhn’s notion of paradigm and paradigm shift from its historical perspectives towards the contemporary advancements of alternate paradigms such as interpretivism, criticalism, post modernism and indigenous research paradigm. Every paradigm follows certain stages from normal science, crisis and revolution or a shift into a new paradigm. The contemporary literature on social science research reveals how decolonization through indigenous research paradigms. The paper then delves into the concept of decolonization and the emergence of indigenous research paradigms. The paper also examines the implications and challenges of indigenous research paradigms, including issues of decolonization among the indigenous communities of the global south. The paper concludes by emphasising the significance of decolonizing research methodologies and identifying the perspectives of marginalized communities. The existing positivist paradigm has been challenged by the critical, interpretive, and post-modern paradigms for a better understanding of social phenomena. Although there has been a positive development in the paradigm shift in social science research, challenges such as the problem of representation and the critique of power and knowledge still exist to be addressed.

The article highlights the problem of demand for divination rituals in modern Korean society. People of all nations have ever had a desire to know about the future, which gave rise to various forms of predictions that persist to this day. However, today this is especially actual for the Republic of Korea, where divination has existed since ancient times as a tradition and now plays an important role in the lives of most Koreans. Because of this, it is difficult to understand whether Koreans follow traditions or follow fashion trends.

Using Lordotic Cages at the L5–S1 Level Does Not Guarantee the Improvement of Sagittal Alignment in Patients Who Underwent Posterior Lumbar Interbody Fusion
Authors: Cho Jae Hwan , Hwang Chang Ju , Lee Dong-Ho , Lee Choon Sung
Published: February 2023

Study Design: Retrospective comparative study.Purpose: This study aimed to investigate the effects of the lordotic angle of cages on sagittal alignment in patients who underwent 1- or 2-level posterior lumbar interbody fusion (PLIF), including the L5–S1 level.Overview of Literature: Few studies have addressed the effects of the lordotic angle of cages on regional and global sagittal balance in patients undergoing PLIF at the L5–S1 level.Methods: Sixty-one patients who underwent 1- or 2-level PLIF, including the L5–S1 level, were divided into two groups based on the lordotic angle of cages (4° and 8° in 41 and 20 patients, respectively). Clinical and radiological parameters were compared. Correlation analyzes were performed to reveal the effect of flexibility and position of cages on the regional sagittal parameters.Results: Pre- and postoperative clinical and radiological parameters were not different between the two groups. Although clinical outcomes improved postoperatively, sagittal parameters did not improve postoperatively in both groups. Patients who underwent 1-level PLIF at the L5–S1 level with the use of 8° cages showed no postoperative improvement (segmental angle: 16.1°–15.9°, p =0.140; lumbar lordosis: 44.8°–47.8°, p =0.740) of regional sagittal parameters. The degree of anterior location of cages showed a positive correlation with the postoperative restoration of the segmental angle (p =0.012 and p =0.050 at 1 and 2 years postoperatively, respectively).Conclusions: Clinical and radiological outcomes based on the lordotic angle of cages were not different. Even with the use of 8° cages and regardless of the more anterior position of cages, sagittal alignment did not improve in cases involving the L5–S1 level. PLIF at the L5–S1 level should be used with caution because improvement in sagittal alignment did not occur.

Cerebral vasospasm as a consequence of pituitary apoplexy: illustrative case
Authors: Alsayadi Somayah , Ochoa-Sanchez Rafael , Moldovan Ioana D. , Alkherayf Fahad
Published: February 2023

BACKGROUND

Cerebral vasospasm is a rare but devastating complication following pituitary apoplexy. Cerebral vasospasm is often associated with subarachnoid hemorrhage (SAH), and early detection is crucial for proper management.

OBSERVATIONS

The authors present a case of cerebral vasospasm after endoscopic endonasal transsphenoid surgery (EETS) in a patient with pituitary apoplexy secondary to pituitary adenoma. They also present a literature review of all similar cases published to date. The patient is a 62-year-old male who presented with headache, nausea, vomiting, weakness, and fatigue. He was diagnosed with pituitary adenoma with hemorrhage, for which he underwent EETS. Pre- and postoperative scans showed SAH. On postoperative day 11, he presented with confusion, aphasia, arm weakness, and unsteady gait. Magnetic resonance imaging and computed tomography scans were consistent with cerebral vasospasm. The patient underwent endovascular treatment of acute intracranial vasospasm and was responsive to intra-arterial milrinone and verapamil infusion of the bilateral internal carotid arteries. There were no further complications.

LESSONS

Cerebral vasospasm is a severe complication that can occur after pituitary apoplexy. It is essential to assess the risk factors linked to the cerebral vasospasm. In addition, a high index of suspicion will allow neurosurgeons to diagnose cerebral vasospasm after EETS early and take the necessary measures to manage it accordingly.
Management of refractory bacterial meningitis–associated cerebral vasospasm: illustrative case
Authors: Norman Sofya , Rosenberg Jon , Sundararajan Sri Hari , Al Balushi Ali , Boddu Srikanth Reddy , Ch’ang Judy H.
Published: February 2023

BACKGROUND

Cerebral vasospasm is an alarming complication of acute bacterial meningitis with potentially devastating consequences. It is essential for providers to recognize and treat it appropriately. Unfortunately, there is no well-established approach to the management of postinfectious vasospasm, which makes it especially challenging to treat these patients. More research is needed to address this gap in care.

OBSERVATIONS

Here, the authors describe a patient with postmeningitis vasospasm that was refractory to induced hypertension, steroids, and verapamil. He eventually responded to a combination of intravenous (IV) and intra-arterial (IA) milrinone followed by angioplasty.

LESSONS

To our knowledge, this is the first report of successfully using milrinone as vasodilator therapy in a patient with postbacterial meningitis-associated vasospasm. This case supports the use of this intervention. In future cases of vasospasm after bacterial meningitis, IV and IA milrinone should be trialed earlier with consideration of angioplasty.
Pineal parenchymal tumor of intermediate differentiation with late spinal dissemination 13 years after initial surgery: illustrative case
Authors: Kato Hiroyuki , Tanei Takafumi , Nishimura Yusuke , Nagashima Yoshitaka , Ishii Motonori , Nishii Tomoya , Fukaya Nobuhisa , Abe Takashi , Saito Ryuta
Published: February 2023

BACKGROUND

Pineal parenchymal tumors of intermediate differentiation (PPTIDs) are rare in the pineal gland. A case of PPTID that disseminated to the lumbosacral spine 13 years after the total resection of a primary intracranial tumor has been reported.

OBSERVATIONS

A 14-year-old female presented with headache and diplopia. Magnetic resonance imaging revealed a pineal tumor that induced obstructive hydrocephalus. A biopsy and endoscopic third ventriculostomy were performed. Histological diagnosis revealed a grade II PPTID. Two months later, the tumor was removed via craniotomy because the postoperative Gamma Knife surgery was ineffective. Histological diagnosis confirmed PPTID, although the grade was revised from II to III. Postoperative adjuvant therapy was not performed, because the lesion had been irradiated and gross total tumor removal was achieved. She has had no recurrence in 13 years. However, pain around the anus newly appeared. Magnetic resonance imaging of the spine revealed a solid lesion in the lumbosacral spine. The lesion was subtotally resected, and histological diagnosis revealed grade III PPTID. Postoperative radiotherapy was performed, and she had no recurrence 1 year after radiotherapy.

LESSONS

Remote dissemination of PPTID can occur several years after the initial resection. Regular follow-up imaging, including the spinal region, should be encouraged.
Spinal dural arteriovenous fistula masquerading as a herniated disc: illustrative case
Authors: Mansour Moustafa A. , Khalil Dyana F. , El-Sokkary Soliman , Mostafa Mostafa A. , Ayad Ahmad A.
Published: February 2023

BACKGROUND

Spinal dural arteriovenous fistula (SDAVF) is a rare disorder with an unknown etiology. Often, the clinical presentation and imaging findings are misleading, causing this condition to be mistaken for other entities, such as demyelinating or degenerative spinal lesions.

OBSERVATIONS

The authors report a challenging case of SDAVF in which the patient’s symptoms were initially thought to be attributable to a herniated disc based on his imaging studies at another institution. He sought the authors for a second opinion, which yielded a confirmed diagnosis of SDAVF. Due to his rapidly progressive neurological manifestations, he underwent a surgical division of the fistula using intraoperative video angiography via indocyanine green injections. His symptoms progressively improved over a 3-month period. He regained full sphincter control by 4 months, which gave him a better recovery than seen in other patients with SDAVFs, who do not generally fully regain sphincter control.

LESSONS

SDAVF is a critical spinal vascular pathology that should not be overlooked in the differential diagnosis of any patient presenting with signs of progressive myelopathy. Despite its associated vague initial clinical symptoms, SDAVF typically, but not always, demonstrates a characteristic imaging appearance on magnetic resonance (MR) imaging studies; therefore, MR angiography is still required for definitive diagnosis. Surgical treatment for SDAVF is almost always definitive and curative.

Abstract. Simulation of calcium and silicon biomineralization made it possible to obtain various composite particles containing an inorganic component and an organic polymer. These particles exist in a variety of forms, from stable aqueous dispersions to solid materials. New composite materials are promising for creating functionalized coatings and three-dimensional structures of different morphology. We prepared composites of calcium carbonate and phosphate by forming an inorganic phase in the presence of water-soluble polymers. The potential of new materials as sorbents for chromatography, 3D bone-like structures, and coatings for cell growth was demonstrated.

Abstract. Ulnaria a us is a cosmopolitan freshwater diatom. As a rule, diatom populations represent a combination of different genotypes. In early study, using a fragment of the rbcL gene of U. acus strains isolated from geographically distant regions, no significant genetic differences were found in the populations of this species. In this paper, we analyzed 41 strains isolated from different regions of Eurasia. Based on the analysis of the 18S rRNA gene fragment, it was shown that all strains form a single clade consisting of U. acus. Phylogenetic analysis of cox1 genes revealed that Eurasian strains of U. acus form three clades. Strains of U. acus from Lake Ritsa (Abkhazia) and Lake Matano (Indonesia) are not heterogeneous. Strains of U. acus isolated from Lake Baikal (Russia) and the r. Erdre (France) contained two clades and we can suggest that the genetic structure of the populations of this species is heterogeneous. All studied populations are conspecific taking into account their sexual compatibility of at least two generations.

Bewertung ist mit Entwertung ebenso verbunden wie die Eingrenzung der Einen mit der Ausgrenzung der Anderen. Dieser Mechanismus, genannt „Externalisierung als Prinzip“, ist bezeichnend für die herrschaftlich geprägte kapitalistische Wertbildung, die systematisch Abwertungen und Ausschlüsse hervorruft. Die Konstruktion dieses externalisierenden Prinzips wird theorie- und ideengeschichtlich analysiert, um sodann nach aktuellen Veränderungen zu suchen: „Wertbeben“ durch COVID-19? Herrschaftsfreie Bewertung ohne Externalisierung in alternativen Handlungsräumen? Die Ergebnisse der Fallstudie laden zu kritischen Reflexionen und zukunftsweisenden Überlegungen ein.

The report presents the results of an analytical study of the industrial provision of Russia with antibiotics in accordance with the new WHO recommendations for the treatment of tuberculosis. The analysis of Russian manufacturers of active pharmaceutical ingredient (API) and dosage form (DF) of anti-tuberculosis drugs was carried out. A conclusion was made about the relative vulnerability of the healthcare system of the Russian Federation in relation to the treatment of tuberculosis: out of 22 types of antibiotics 5 are produced only from imported API, 13 are produced from imported and domestic API (quasi-import), 2 types are not produced in the Russian Federation, but are allowed for import, 2 types are not registered in the Russian Federation. In the production of 13 types of antibiotics, the share of API suppliers from Russia does not exceed 27%. The share of foreign API suppliers in the production of pharmaceutical products in Russia is as follows: India (5–100%), China (3–81%), Israel (4%), Republic of Korea (7–63.5%), Taiwan (3%), Thailand (20-40%), EU (3-100%). Maps showing the main territorial clusters of drug manufacturers and API suppliers are presented. The logistical risks and logistical connections of the participants in the production of drugs are described.

Introduction: Recent studies have revealed the possibility of learning skills through alternative methods and repetitive tactile stimulation without explicit training. This study aimed to examine the effect of involuntary tactile stimulation on the memory and creativity of healthy participants. Methods: A group of 92 right-handed students participated in this study voluntarily. They were assigned to the experimental (n=45) and control (n=47) groups. The participants performed two creativity tests (divergent and convergent thinking) and a verbal memory task as the pretest. Then, the experimental group received 30-min involuntary tactile stimulation on the right index finger, and the control group did not. In the posttest, both groups were asked to perform the creativity and verbal memory tasks again. Results: The learning score and speed of the Rey auditory-verbal learning test in the stimulation group significantly increased (P=0.02). Moreover, in the creativity-related tests, there was a significant effect of the intervention on convergent thinking, i.e., the remote association task (P=0.03), but not for the divergent thinking, i.e., the alternative uses test (P>0.05). Conclusion: Using involuntary tactile stimulation on the index finger of the right hand of individuals could enhance their performance in verbal memory and creativity-convergent thinking.

Background/Objectives: Nephrotic syndrome (NS) relapses are usually triggered by infections. Treatment of infections will be sufficient to cause resolution of symptoms. Our study aimed to determine frequency of spontaneous remission and its predictors. In addition, our main objective was to know the outcome of children after spontaneous remission of relapses for next 6 months.
Materials and Methods: Prospective cohort study included all children who presented with NS relapses. Seventy-four children were enrolled from November 2016 to May 2018. Both, spontaneous remission YES and NO groups, were followed up for 6 month duration to study relapse free period and relapse rate.
Results: About 53.7% relapses remitted spontaneously with only stress dose steroids. Duration of illness more than 24 months could predict likely chances of spontaneous remission RR 0.49, 95% CI 0.29–0.87 (p=0.003). Outcome parameters, that is, relapse free period and relapse rate were similar in both groups.
Conclusion: About 50% of NS relapses will remit spontaneously with only stress dose of steroids and if required antibiotics. Waiting period of 1 week for clearance of infection and occurrence of spontaneous remission may be necessary before contemplating long steroid course for all relapses. Further studies are required with large sample size.

Introduction: The most vulnerable period of human life is neonatal period, which accounts for most of the morbidities and mortalities. Most of them are preventable with adequate health-care facilities.
Objectives: The aim of the study was to determine the trends of neonatal mortality and identify the risk factors, most of which are preventable and measure the progress of health-care services.
Methods: A retrospective study was conducted in neonatal intensive care unit (NICU) of Al-Ameen Children Hospital (AMCH) Vijayapura, Karnataka, India. Data were extracted from paper medical records at AMCH of a period of 1 year and digitized. Data obtained included age, sex and birth weight, place of delivery, morbidity profile, mortality profile, diagnosis, and period of stay in NICU.
Results: A total of 648 neonates were admitted in NICU during the study period of 1-year duration, between January and December 2021. A total of 382 (58.9%) infants were discharged on recovery, 65 (10.3%) were referred due to unavailability of advanced surgical intervention, 39 (6%) were discharged against medical advice, 162 (25%) died due to various reasons. Male neonatal deaths outnumbered female neonates (56.8%). Among the total neonatal deaths, 82 (50.6%) were preterm neonates, 73 (45.1%) were term neonates and 7 (4.3%) were post-term neonates. It was noticed that among neonatal deaths, 87 (54.3%) babies were out-born and 75 (46.2%) babies were inborn. In this study, it was noticed that the mortality percentage of the neonate falling in the category of 1.5–1.9 kg was high compared to other categories. In our study, respiratory distress syndrome was the main cause of mortality accounting for 19.1% (31 cases) of total cases and prematurity was the most common risk factor.
Conclusion: Improving the standard of antenatal care and encouraging deliveries in institutions having good NICU facility and early identification of risk factors help to reduce the mortality and its complications.
