Analysis and Prediction of College Students’ Mental Health Based on K-means Clustering Algorithm
Authors: Liu Yanwu 
Published: February 2022

Abstract
Mental health is an important basic condition for the adult development of college students, and education workers gradually pay attention to the strengthening of mental health education for college students. In this paper, a psychological management system based on the K-means clustering analysis method is proposed. Based on the basic functions of the traditional system, the students’ psychological data are reutilised by using the idea of data mining. By optimising the iterative process of the K-means algorithm, the valuable parts of a large number of precipitation students’ psychological data are extracted. A data model is established and it provides decision guidance for managers to scientifically manage students’ mental health process. The system establishes the data mining model in the process of analysis, carries on the mining to the students’ psychological data in the database, analyses the different college students’ mental health state characteristics and provides the corresponding solution. The part of the test drew on mental health data from 1,000 students at a school, and the results show that the system uses the k-means algorithm to divide students into 3 categories, which are 20.6%, 31.9% and 47.1% respectively, which are 1.6% different from the data test results in the ideal state.
Who is Most Vulnerable? Exploring Job Vulnerability, Social Distancing and Demand During COVID-19

Published: February 2022

Abstract
COVID-19 has resulted in global lockdowns, social distancing and demand fluctuations. Existing crisis management research often provides a retrospective account of strategy making after a crisis. Limited studies have explored the factors which aid policy responses during an ongoing crisis. This research helps fill this gap by exploring the influence Covid-19 had on job vulnerability during the first wave of the COVID-19 crisis (spring and summer of 2020). We explore Northern Ireland (NI) which historically has experienced disadvantages. We utilise point-in-time modelling which considers contextual variations. The findings reveal that a reduction in social distancing reduces the vulnerability of over 30,000 jobs, however, ongoing uncertainties regarding demand will have a more significant longer-term impact on job vulnerabilities. We identify how COVID-19 may impact sectors, groups and geographies differently. We provide policy recommendations on how to alleviate the impact COVID-19 has for job vulnerability across the NI economy.
Teaching in Flexible Spatial and Digital Conditions
Authors: Sofkova Hashemi Sylvana , Hipkiss Anna Maria 
Published: February 2022

This study explores the opportunities and challenges of teaching under flexible spatial and digital conditions of the learning environment of a newly build school analyzing how teaching is organized and what curricular genres can be discerned, what resources and practices are offered to stimulate students meaning-making and what framing, relations and accessibility can be discerned in the flexibility of furniture and classroom space. The analyses of one teacher team’s planning and teaching of the thematic work project on Space in years 2-3 (8-9 old children) reveals varied teaching strategies between teacher-led and student-centered forms offering students linguistic, visual and audiovisual resources to make meaning of shared content via different subjects. Spatial framing allows for free movement or static and focused teaching strategies of rather traditional forms of assignments and assessment. These young students practice reading comprehension, both of written texts and films, that also serves building their knowledge about space, thus engaging in skills discourse in combination with thinking and learning discourse.

Published: February 2022

La ozonización catalítica (OC) es una tecnología prometedora en términos de eficiencia y costo energético como tratamiento de efluentes industriales que poseen contaminantes de preocupación emergentes, ya que mejora las capacidades oxidativas del ozono a través de catalizadores que promueven su descomposición y la generación de especies radicales oxidantes, los cuales reaccionan con prácticamente cualquier compuesto presente en los efluentes. Este artículo estudió el estado y evolución de la OC mediante una revisión de la literatura y un análisis bibliométrico combinado con la técnica de curva S para analizar cuantitativamente 1714 publicaciones en SCOPUS y SciELO Index desde el año 1973 al 2021.
Los resultados mostraron que (1) el número de publicaciones a nivel mundial se inició en 1973 a tuvo 189 documentos en 2021; (2) China es el país con mayor número de publicaciones y citaciones anuales (958 y 19088, respectivamente) y es un país central en redes de cooperación internacional; (3) tanto el estado del arte como el análisis de co-ocurrencia de palabras clave mostró que la investigación ha priorizado mecanismos de reacción de la OC, expresiones cinéticas, catalizadores, y desde 2016, la aplicación a escala piloto en conjunto con otras tecnologías avanzadas de oxidación; (4) El compuesto con más investigaciones es el ácido oxálico y desde 1999 ibuprofeno y atrazina; (5) en América Latina, Brasil es el país con más publicaciones (32) y con mayor número de redes de cooperación internacional y (5) Applied Catalysis B: Environmental y Journal of the Brazilean Chemical Society (América Latina) son las revistas con mejor cuartil que publican sobre OC. Finalmente, la curva S indicó que la OC se encuentra en etapa de crecimiento en términos de madurez cientifica, exhibiendo un gran potencial en I+D.
An echocardiographic study of the effect of obesity on systolic and diastolic functions of the left ventricle in hypertensive adults
Authors: Shree C. Mamatha , Prashanth K. S. , Girija B. 
Published: February 2022

Objectives:
The objectives of the study were to examine the effect of obesity on echocardiographic parameters of systolic and diastolic functions of the left ventricle (LV) in asymptomatic hypertensive adults.

Materials and Methods:
A cross-sectional study was conducted with 100 individuals (65 males and 35 females). Their blood pressure and body mass index were recorded following which they were divided into obese hypertensives and non-obese hypertensives. Echocardiographic examination was done, and parameters indicating LV geometry and function were recorded. Data were statistically analysed for differences. An unpaired t-test was used considering P < 0.05 as a significant value.

Results:
Echocardiographic parameters of LV diastolic function were significantly altered in obese hypertensives compared to non-obese hypertensives (P < 0.05). About 58% of non-obese hypertensives and 78% of obese-hypertensives had LV diastolic dysfunction. About 6% of non-obese hypertensives and 8% of obese-hypertensives had LV systolic dysfunction.

Conclusion:
Obesity in hypertensive individuals adds risk for diastolic dysfunction. The number of subjects falling into categories of mild-to-moderate diastolic dysfunction was considerably higher in the obese hypertensives compared to the non-obese hypertensives.

Authors: Adeyomoye Olorunsola Israel , Olaniyan Olugbemi Temitope , Adewumi Nifemi , Anyakudo Magnus Michael 
Published: February 2022

Objectives:
Lead is an environmental toxicant known to cause dyslipidaemia through oxidative stress damage. The therapeutic potential of honey has widely been reported. However, there is a paucity of reports on its effects on lipid profile in Wistar rats exposed to lead.

Materials and Methods:
The effects of honey on antioxidants and lipid profile indicators were studied in 25 male Wistar rats. The rats were randomly assigned to one of the five groups (n = 5) as follows: Group I served as the control and received deionised water; Group II served as a lead acetate group (40 mg/kg bw) and Groups III, IV and V served as lead acetate groups coadministered with honey (1 mL/kg bw), Vitamin C (100 mg/kg bw) and honey+Vitamin C, respectively. The treatments were orally administered for 28 days. Body and liver weights were determined using an analytical weighing balance. Glucose and lead concentration, superoxide dismutase (SOD), total antioxidant capacity (TAC), malondialdehyde (MDA), and the lipid profile indicators were determined using spectrophotometry. The liver histology was assessed by haematoxylin and eosin staining techniques. Statistical analysis was done using analysis of variance, and the results were expressed as mean ± S.E.M. at P < 0.05.

Results:
Body weight, SOD, and TAC increased significantly in the treatment groups compared to lead acetate only. However, lead, glucose concentration, MDA, total cholesterol, triglycerides, HDL, and LDL decreased significantly in the treatment groups compared to lead acetate only. Normal histoarchitecture of the liver was seen in the treatment groups compared to lead acetate, which showed areas of inflammation.

Conclusion:
These findings imply that honey prevents dyslipidaemia which is a risk factor for metabolic diseases.
The role of histamine in anterior pituitary secretion
Authors: Faris Afrah Nasserallah , Al-Fartosi Khalid G. , Al-Snafi Ali Esmail 
Published: February 2022

Objectives:
The aim of the present study was to determine the effects of histamine on the anterior pituitary secretion in rats.

Materials and Methods:
In the first experiments rats were injected with histamine 5 mg/kg i.p., and blood samples were collected to determine the effect of histamine on serum level of adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), prolactin, FSH, and luteinizing hormone (LH) after 10, 20, and 30 min of histamine injection. In the second experiments, rats were treated with (H 1 blocker), chlorphenramine 10 mg/kg, i.p. or (H 2 blocker), cimetidine 80 mg/kg, i.p. respectively, and after 30 min they were injected with histamine and blood samples were taken 30 min after the injection of histamine to determine the same hormones.

Results:
Histamine significantly elevated serum ACTH and LH level, and these stimulatory effects were inhibited by both H1 and H2 receptor blockers. However, histamine significantly inhibited the serum level of thyroid-stimulating hormone and this inhibitory effect was blocked by H2 receptor blocker, while it showed no effect on the secretion of both prolactin and FSH, although H2 blocker significantly decreased prolactin level and H1 blocker significantly elevated FSH level.

Conclusion:
The results clearly indicated that histaminergic pathways were involved in the anterior pituitary secretion.
Diagnosis and management of thoracic intradural extra-arachnoidal disc herniation
Authors: Safi Saleh Salah , Allyan Abdulla , Ali Arshad , Raza Ali 
Published: February 2022

Background:
Intradural extra-arachnoidal disc herniations (IEDHs) are rare. Here, we reviewed the clinical features and magnetic resonance (MR) diagnostic features of IEDH.

Case Description:
A 58-year-old male presented with mid-thoracic back pain radiating to the left leg associated with ipsilateral leg weakness. The thoracic MR documented T8-T9 focal spinal canal stenosis and a ventral disc herniation. Thoracic spine computed tomography scan confirmed the diseased level and did not show any calcification. The patient underwent a right-sided transpedicular extracavitary approach for disc excision. At surgery, IEDH was identified with soft cartilaginous consistency and was morcellated to remove in piece meal while preserving the integrity of the arachnoid layer.

Conclusion:
IEDH poses a significant challenge for its diagnosis and management. A careful preoperative MR imaging review with a high index of clinical suspicion may ensure a good clinical outcome.

Background:Myths and religion are belief systems centered around supernatural entities that attempt to explain the observed world and are of high importance to certain communities. The former is a collection of stories that belong to a cultural tradition and the latter are organized faiths that determine codes of ethics, rituals and philosophy. Deities or monstrous creatures in particular act as archetypes instructing an individual’s conduct. References to them in Greek mythology and Christianity are frequently manifested in the modern neurosurgical vernacular.Methods:A review of the medical literature was performed using the PubMed and MEDLINE bibliographic databases. Publications from 1875 to 2021 related to neurosurgery or neuroanatomy with the medical subject headings (MeSH) terms mythology, religion, Christianity and Catholicism were reviewed. References pertaining to supernatural beings were classified to either a deity or a monstrosity according to their conventional cultural context.Results:Twelve narratives associated with neurosurgery were identified, nine relating to Greek mythology and three associated with the Christian-Catholic faith. Eight accounts concerned deities and the remaining with monstrous creatures.Conclusion:This article explores the etymology of commonly utilized terms in daily neurosurgical practice in the context of mythology and religion. They reveal the ingenuity and creativity of early pioneers who strived to understand the brain.
Endoscopic third ventriculostomy for the management of hydrocephalus secondary to posterior fossa tumors: A retrospective study
Authors: Salah Mohamed , Elhuseny Ahmed Yahia , Youssef Essam M. 
Published: February 2022

Background:
Endoscopic third ventriculostomy (ETV) is an effective alternative to ventriculoperitoneal shunting as well as external ventricular drainage for the urgent management of acute hydrocephalus. We performed this study to investigate the efficacy and safety of ETV before tumor resection in managing hydrocephalus in patients with posterior fossa brain tumors (PFBT) in our neurosurgery department.

Methods:
We conducted this retrospective observational study between February 2018 and February 2020 on all cases diagnosed with PFBT associated with triventricular obstructive hydrocephalus. We retrospectively reviewed the demographic characteristics, operative procedures, and radiological investigations of all cases. During the follow-up period, clinical, as well as radiological success were evaluated.

Results:
Twenty-two ETV procedures were performed in 22 cases of PFBT (mean age = 22.1 years, SD = 11.4). Of the 22 cases, 8 cases (36.4%) had ependymoma, 7 cases (31.8%) had cerebellar astrocytoma, and 5 cases (22.7 %) had medulloblastoma, while 2 cases (9.1%) had diffuse pontine gliomas. The median follow-up duration was 9 months (range 3–13 months). The most commonly reported clinical presentation was the significant intracranial pressure increase. All operations were performed successfully in all cases. Only two ETV post-tumor resection failures were documented during the follow-up period.

Conclusion:
Preoperative ETV has shown to be an effective long-term cerebrospinal fluid diversion procedure to manage PFBT-associated hydrocephalus, with a relatively low rate of complications. Further prospective studies are required to assess the regular use of ETV before complete tumor resection.
