Pragmatic Approaches to Reducing Radiation Dose in Brain Computed Tomography Scan using Scan Parameter Modification
Authors: Choopani Mohammad Reza , Abedi Iraj , Dalvand Fatemeh
Published: August 2022

Background:

High radiation dose of patients has become a concern in the computed tomography (CT) examinations. The aim of this study is to guide the radiology technician in modifying or optimizing the underlying parameters of the CT scan to reduce the patient radiation dose and produce an acceptable image quality for diagnosis.

Methods:

The body mass measurement device phantom was repeatedly scanned by changing the scan parameters. To analyze the image quality, software-based and observer-based evaluations were employed. To study the effect of scan parameters such as slice thickness and reconstruction filter on image quality and radiation dose, the structural equation modeling was used.

Results:

By changing the reconstruction filter from standard to soft and slice thickness from 2.5 mm to 5 mm, low-contrast resolution did not change significantly. In addition, by increasing the slice thickness and changing the reconstruction filter, the spatial resolution at different radiation conditions did not significantly differ from the standard irradiation conditions (P > 0.05).

Conclusion:

In this study, it was shown that in the brain CT scan imaging, the radiation dose was reduced by 30%–50% by increasing the slice thickness or changing the reconstruction filter. It is necessary to adjust the CT scan protocols according to clinical requirements or the special conditions of some patients while maintaining acceptable image quality.

Authors: Banifatemi Mohammad , Nilforushan Naveed , Sedaghat Ahad , Miraftabi Arezoo , Abolfathzadeh Navid
Published: August 2022

Purpose:

To report a case of ciliary body melanoma with acute high intraocular pressure (IOP) due to pigment dispersion, treated by limited trans-scleral cyclophotocoagulation (TSCPC) and plaque radiotherapy.

Methods:

A 33-year-old woman was referred to clinic with acute ocular pain and decreased visual acuity from 1 week before presentation. The IOP was 55 mmHg accompanied by red eye, perilimbal injection, mild corneal edema (stromal and epithelial), scattered pigment dust on central corneal endothelium, 4+ anterior chamber pigments, and pigmented cells. Gonioscopy revealed a bulging mass posterior to the iris root, about 2 o'clock width alongside a heavy dark brown pigmentation of all angle structures. Ultrasound biomicroscopy confirmed a ciliary body mass of about 4.5 mm × 4 mm × 3.3 mm in the superior ciliary region, in favor of melanoma. Due to no response to maximal antiglaucoma therapy, a limited TSCPC in the inferior hemisclera was done. After control of the IOP, plaque radiotherapy with Ru-106 was done.

Results:

Three days after the cyclophotocoagulation, IOP decreased to 18 mmHg. Visual acuity reached to 20/25 and IOP remained 18 mmHg, with timolol/dorzolamide drop twice a day. Anterior chamber pigments gradually decreased, and antiglaucoma and steroid drops were tapered during 1 month, thereafter. The IOP was 14–16 mmHg with timolol/dorzolamide bid at months 3 and 6 of follow-up and 21–22 mmHg without any drop at months 12 and 18, with no sign of glaucomatous optic neuropathy.

Conclusion:

Limited cyclophotocoagulation may be a good choice for controlling the high refractory IOP in cases of intraocular neoplasms such as ciliary body melanoma, which are planned for salvage therapy such as plaque radiotherapy.

Published: August 2022

Background:

Two-dimensional speckle-tracking echocardiography (2D STE) has been used by many cardiologists globally for assessing the left ventricle (LV) function by having global longitudinal strain (GLS) as an important parameter; however, it is not incorporated into daily practice and some studies have proved to be a better diagnostic value for evaluation of detecting significant coronary artery disease (CAD) and also in predicting the culprit coronary artery.

Methods:

We enrolled 100 consecutive symptomatic patients with suspected CAD who have undergone angiogram in our institute. Out of these, 21 patients had poor echo window and were excluded. The patients were divided into two groups those presenting with acute coronary syndrome ST-elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and others with stable angina. All patients underwent a 2D echocardiogram, 2D strain imaging, and coronary angiogram.

Results:

GLS correlated well with ejection fraction in our study. GLS was more impaired in patients with double- and triple-vessel disease than in patients with single-vessel disease. The number of patients presented with STEMI is 26 (anterior wall myocardial infarction – 20 and inferior wall myocardial infarction – 6), 23 had NSTEMI, and 30 had stable angina. The results of regional peak systolic strain had a stronger correlation with coronary angiogram in stable angina (P = 0.03), but in ACS patients, it was not significant (P = 0.136). This correlation was better in patients with adequate LV systolic function (P < 0.05) than patients with left ventricular systolic dysfunction (P = 1.0).

Conclusion:

2D STE is a simple, noninvasive, and reproducible diagnostic tool in the evaluation of CAD and is immensely helpful in the localization of culprit vessel in chronic coronary syndrome.

Authors: DEMİR Murat
Published: August 2022

Three-dimensional (3D) printing has an increasing popularity in recent years with easy availability and the wide range of applications in many fields. While producing textile-like structures with 3D technology is still a challenging problem, combining textiles with 3D printed structures enables the manufacture of many alternative structures in the field of textile applications. This study investigates the effect of 3D parts with different infill patterns printed onto the cotton woven fabric for tensile strength. For this purpose, 3D parts with concentric, grid and triangle infill patterns were printed onto plain and twill woven fabrics with polylactic acid (PLA) filaments in the Fused Filament Fabrication technique. Adhesion between fabric and 3D parts and tensile strengths of produced structures were measured to assess the effectiveness of 3D printing. Results showed that greater adhesion between 3D parts and fabrics were obtained for plain-woven fabrics. The infill patterns were also found effective for the tensile strength performance.

The Internet is an integral part of human society and everyday life of most people, and it may be used for satisfying various human needs. The Internet has changed the way we process information, learn, talk, behave, etc. However, when something is used too much, it always brings some consequences with it, one being Problematic Internet Use, which is an umbrella term that encompasses a wide range of repetitive disabling behaviours, such as Internet video gaming, gambling, cyberpornography addiction, compulsive online shopping, social networking problematic use, and so on. In this paper, different views on Internet use in modern society will be considered, from ideas (over)emphasising its harmful effects on users’ health, to ideas ignoring these warnings. We will be discussing the advantages of ICT use, as well as characteristics of the Internet, which may ease a compulsive use or preoccupation with online content and activities. We will particularly focus on classification criteria for specific online behaviours into the category of problematic use or Internet addiction, and finally we will point to some of the negative effects of PIU, as well as types of such Internet-related problems.

Published: August 2022

The world's resources dedicated to fisheries and aquaculture are predicted to remain stable at their maximum utilization rate. Many intensive fish farms with recirculation production systems are needed in order to achieve sustainable output. Combined or integrated production projects are needed for sustainable production and to meet the high demand for food supplies. However, due to a substantial migration problem from rural areas to metropolitan centers, labor may be a concern in the aquaculture business. Turkey is still improving technology in order to maximize resource utilization while minimizing disruption to aquatic systems. With the growth of aquaculture, some environmental issues have been identified. Based on the present study, it was predicted that Tukey will produce 700,000 tons of fish by 2050. The purpose of this paper is to provide an overview of the current situation, as well as studies on sustainability and future developments in the field.

Published: August 2022

The character crisis is an issue of many countries. For many children, the school is an uncaring environment, that can cause a negative impact in mental health, so we can see the output of school residents is not in a good character. In fact, schools have an important role in the psychosocial development of children. Seeing this fact, UNICEF developed a child-friendly school program to solve the problem. Its also necessary to evaluate the child friendly school programme, then it will be discussed about CIPP model too. The results of the review found that child-friendly schools can be optimal if principals, teachers and education staff, and school committees collaborate well in carrying out their roles in realizing the six principal components of child-friendly schools. Research on this topic is limited and this article is a literature review, so it is necessary to conduct further research using interview and questionnaire methods related to the role of child-friendly schools in building student character.

Authors:   Sankalchand Patel University, Visnagar, Zalak Dr. Patel
Published: August 2022

Anterior open bite treatment is considered to be a complex treatment in the field of orthodontics. Orthognathic surgery is often the treatment of choice for these types of malocclusions and prognosis of the results are still questionable. With the introduction of Multiloop edgewise archwire therapy, treatment of open bite has started showing efficient results. Moreover, MEAW is versatile as it is capable of correcting various malocclusions as well such as Class II, Class III, deep overbite, and malocclusions with marked midline deviations. Since the advent of the MEAW, its treatment modality has been used worldwide and numerous reports of successful results have been published. Some orthodontists have described the MEAW technique as “magical” or “unbelievable,” but it certainly is not. The diagnosis and treatment plan must be correct and construction of the MEAW must be precise to deliver the necessary forces to move the teeth to an optimal, stable relationship.Hence this article aims to review the multiloop edge wise arch wire technique in detail along with its biomechanics.
Monitoring of parasites in bumblebee colonies developed from controlled nesting of wild queens (Hymenoptera: Apidae: Bombus)
Authors: Gekière Antoine , Habay Jean , Michez Denis
Published: August 2022

Bumblebees (Apidae: Bombus spp.) are a major group of wild and domesticated bees that provide crucial ecosystem services through wildflower and crop pollination. However, most of bee populations, including bumblebees, are declining worldwide, partly because of parasite spill-over and spill-back between bumblebee commercial colonies and wild populations. Breeders have to cope with invasions by a vast array of bumblebees’ parasites, and techniques need to be developed to prevent such invasions to support breeders and wild bee populations. Our 10-year study is based on 327 nests of seven bumblebee species (B. humilis, B. hypnorum, B. lapidarius, B. lucorum, B. pascuorum, B. sylvarum, B. terrestris) reared in outdoor boxes. Some boxes were equipped with parasite-preventing techniques, namely (i) an airlock (n = 2) or (ii) an additional chamber with natural fragrances (n = 74). We recorded the invasion of the nests by the wax moth Aphomia sociella, the eulophid Melittobia acasta and the cuckoo bumblebees Bombus subgenus Psithyrus spp. Overall, 8.26 %, 1.53 % and 3.67 % of the colonies were invaded by A. sociella, M. acasta and Psithyrus spp., respectively, without coinfection. Neither the airlock nor the additional chamber with natural fragrances prevented A. sociella infestation. Despite that no nest equipped with an airlock or an additional chamber with natural fragrances was invaded by M. acasta or Psithyrus spp., we lacked replicates to properly demonstrate the efficiency of these techniques. Nest inspection remains a time-consuming but powerful technique to reduce artificial nest spoilage by parasites, yet it is inefficient against tiny invaders (< 1 mm) that are left unnoticed. We therefore encourage further studies to actively seek for parasite-preventing techniques to reduce artificial nest spoilage and to mitigate spill-over towards wild populations.
Overlaps between minimum requirements and capital buffers: the usability of the combined buffer requirement for Italian banks
Authors:   Banca di Italia, Cornacchia Wanda , Guerra Giulio ,   Banca di Italia
Published: August 2022

The current EU capital regulation requires that banks comply with two main frameworks at the same time: one for prudential purposes, the other for resolution purposes. The first one includes both a risk-weighted requirement (RW) and a leverage ratio requirement (LR). Similarly, the resolution framework, which ensures that banks have enough loss-absorbing and recapitalization capacity through a Minimum Requirement of Eligible Liabilities (MREL), is based on two ratios that are to be met in parallel: the MREL as a percentage of risk weighted assets (MREL-RW) and the MREL as a percentage of the total exposure measure used for the purpose of the leverage ratio (MREL-LR). According to the EU regulation, the CBR is only required on top of the two risk-weighted requirements (RW and MREL-RW).
Beyond VaR and Expected Shortfall: The Stress Testing/Scenario Analysis approach for protecting the investors in the post-Covid19 era
Authors:   CIIA, Independent Investment & Risk Analyst, Macchia Gianluca
Published: August 2022

With political and economic scenarios changing at an ever faster pace, it is necessary to understand the potential effects on asset prices. Today, the topic of rising inflation in the US as well as in the Eurozone, although still considered temporary by central banks, confronts us with the "unexpected risk" of a deviation from the baseline scenario. This implies the risk of having an aggressive monetary policy in the US, in a restrictive direction, therefore harmful to the financial markets. In this context, the question arises: is it possible to contemplate these events beforehand and act in good time? The answer is Yes and good risk management practices are important, using stress testing / scenario analysis techniques to accompany risk measures such as VaR and Expected Shortfall. Implementing this concept, through the implementation of stress test / scenario analysis - Bloomberg Economics Forecast Models® and Bloomberg Factor Models® - the present work seeks to consider plausible adverse scenarios that may arise and to assess the related impacts in terms of portfolio. The final aim is to improve the information set for the investor, allowing him to avoid potential market falls, as far as possible, that could prevent him from achieving his investment objectives.

Published: August 2022

The estimate of the probability of default plays a central role for any financial entity that wants to have an overview of the risks of insolvency it may incur by having economic relations with counterparties. This study aims to analyze the calculation of such measure in the context of counterparty risk from a current and prospective standpoint, by using dynamic neural networks. The forecasting aspect in the calculation of such risk measure is becoming more and more important over time as current regulation is increasingly based on a "Through the Cycle" and not a "Point in Time" assessment, consequently giving fundamental importance to such estimate. To this end, three different models aimed at calculating the Probability of Default have been investigated: the CDS method, the Z-Spread method, and the KMV method (Kealhofer, Merton and Vasicek). First, the different techniques have been applied to one of the main suppliers of gas and energy in Italy as a reference company. Then, they have been applied to calculate the same risk measure on the 50 companies included in one of the most important European indices, the Euro Stoxx 50.

Authors: Magaji J.Y. , Oluyori N. R.
Published: August 2022

In order to ensure availability and sustainable management of water and sanitation for all, as a set target for Sustainable Development Goals (SDG), there is every need to manage and monitor the sources and availability of water resources. One of those strategies is to investigate the level of water pollution and proffer management strategies.
Purpose: The aim of this study was to assess the water quality of surface water in Mpape dumpsite and its environs.
Methodology: A total of 15 water samples were analysed for 27 parameters during the rainy seasons in 2019. The data was then compared with the World Health Organization standard.
Findings: Temporal analyses revealed that all the water samples collected at three different times across the five different sampling points exhibited low variation in their quality, except Cd in sample 1, pH in sample 3, Cd and Cn in control sample 1 and 2 respectively have high variations, while DO and Fe in sample 2, Hg and Fe in control sample 1 and 2 respectively, varied moderately. Biological analysis shows that all the water samples used for the study have feacals, such as Salmonella, Shigella, and E-coli. Spatial analysis result showed that there was high variation between the sampling points though statistically the variation was not significant. Statistically, there was significance difference in pollution level between the dumpsite and the control samples at α=0.05. About 40% of the analysed parameters were above the WHO standard, and 46.7% is within the limit, while 13.3% their permissible limits were not mentioned.
Recommendation: It was therefore recommended that the water be treated before use and the public should be sensitized on the need to always purify their water before consumption. The authority concern should embark on regular monitoring and treatment of the polluted water in order to achieve goal 6 of the SDG.
Apoptosis in cancer

Published: August 2022

Apoptosis is a programmed cell death mechanism, with its presence and absence, directs the progression of most diseases and is targeted in disease treatments. Many factors are influential in the cell's pathway to apoptosis. The defects in these pathways may transform the cell become malignant, and the organism may face a lethal outcome such as cancer. Understanding apoptosis will provide clues in guiding the pathogenesis of diseases. Two main pathway leading to apoptosis, intrinsic and extrinsic, take an active role. Another route is activated by enzymes and enzymes secreted by immune cells such as T and NK. With their initiator and enforcer roles, many caspase molecules are active at critical points in the cell's apoptosis process. In cancer treatments, activation of molecules in these pathways and repair of disrupted pathways are among the target approaches. This review discuss target strategies for inhibiting apoptotic pathways and molecules in cancer cells and the activation of these apoptotic pathways.
Investigating understandings of critical literacies among Finnish and Canadian teachers
Authors: Louloudi Eleni
Published: August 2022

Critical literacy has been defined as the use of analog and digital materials towards questioning and deconstructing problematic and oppressive societal norms and further reconstructing more socially just narratives. Even though critical literacy is a well-known concept in many English-speaking countries, its application and significance in Europe have not been sufficiently investigated. As a result, this dissimilar study of the concept can be reflected in teachers’ understandings of it in theory and in practice. This contribution focuses on exploring and reconstructing teachers’ perspectives of critical literacies comparatively. More specifically, the article highlights similarities and differences in the way teachers from Canada and Finland think of the definition and implementation of critical literacies in their own situated, socio-cultural and socio-educational contexts. The study is based on theory-generating expert interviews and a comparative case study design, and the analysis of the data follows a grounded theory framework. The main results show a considerable convergence in perspectives; while Canadian teachers explored connections of critical literacies with social justice education, Finnish teachers rather highlighted ideas of information management and multiliteracies. Nevertheless, there were noticeable connections among these perceptions which are relevant for the development of the field and are further explored in the discussion part of this article.

Analytical Study of Rectangular Concrete-Filled Tubes (RCFT) Connections using Finite Element Analysis under Cyclic Loading
Authors: Casita Cintantya Budi , Suswanto Budi , Komara Indra
Published: August 2022

Recent condition of the earthquakes model has shown that rectangular concrete-filled tubes (RCFT) with weld connection are so brittle. According to the studies conducted, large damages are due to the cracking of the weld between the beam flange and the column face and inducing concentrated stresses in this area. One of the novel alternatives to reduce the stress concentration at the panel zone could be the use of the reduce beam section (RBS). Given the enormous impact of seismic behaviour and ductility of the panel zone, RBS moves plastic hinges formation at an appropriate distance from column face. In this study, 2 major model of RCFT with and without RBS have been modeled using ABAQUS computer program and compared under cyclic behaviour. The obtained result of this study showed that using RBS is more ductile and implied a good stability. It also will consider having better ductility than other connections.

Impact of COVID-19 on patients treated with autologous hematopoietic stem cell transplantation: A retrospective cohort study
Authors: Silfverberg Thomas , Wahlin Björn , Carlson Kristina , Cherif Honar
Published: August 2022

Objective: To describe how coronavirus disease 2019 (COVID-19) affects patients with hematological malignancies treated with autologous hematopoietic stem cell transplantation (ASCT).

Methods: This retrospective observational cohort study includes all patients with hematological malignancies treated with ASCT in Sweden from 1 January 2020 to 31 December 2020. Patients who subsequently tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) until 31 March 2021 were analyzed for morbidity, mortality, need for supportive care, and risk factors related to COVID-19.

Results: This study identified 442 patients who underwent ASCT in Sweden in 2020, among whom 20 (4.5%) subsequently tested positive for COVID-19. The overall mortality was 15%, and the COVID-19-related mortality was 10% among the patients who contracted COVID-19. Six (35%) patients were hospitalized, of which four (24%) needed supplementary oxygen and two (12%) needed intensive care. The absolute risk of COVID-19-related mortality was 0.45%.

Conclusions: ASCT patients have a higher risk of severe outcome of COVID-19 compared to the normal population. However, the risks of death, inpatient care, oxygen therapy, and intensive care seem lower in this study compared to previous studies, possibly due to fewer mildly ill patients in other studies. The risk of contracting SARS-CoV-2 appears to be comparable to that in the general population. This study suggests that the COVID-19 pandemic is not a strong argument for refraining from ASCT in the case of hematological malignancy.

Hecho trascendente de nuestra historia reciente, desde el “Cordobazo” del 29 de mayo de 1969 -Montoneros se da a conocer en el primer aniversario del “Cordobazo” con el ajusticiamiento del General Pedro Eugenio Aramburu, y en ese mismo 1970, el Partido Revolucionario de los Trabajadores (PRT) crea en su V Congreso a su brazo armado, el Ejército Revolucionario del Pueblo (ERP)–, hasta el golpe de Estado de 1976 –momento en que se produce la catastrófica derrota de los movimientos populares.
Analysis of the First Pressure Derivative of the Isothermal Bulk Modulus using the Brennan-Stacey, Ullmann-Pankov, and Vinet-Redberg Equations of State for MgO and CaO Solids
Authors: B. P. Maurya  , S. Singh
Published: August 2022

In order to extend a prior study and derive accurate values for theand its initial pressure derivative, isothermal bulk modulus, the main objective of the current study is to analyse the link between the three EOSs. The three EOSs that are taken into account are the Vinet-Redberg, Walzer-Ullmann-Pankov, and Brennan-Stacey equations of state. We utilized all three EOS experiments in comparison for two solids. The compression and pressure range variation have been used to assess the applicability.

Nexus of Overall Cost of Celebrity Endorsement and Market Performance of Alcoholic Brewery Products in Lagos Metropolis, Nigeria
Authors: Gbadebo Akindele, , Kingsley Arogundade, Kayode
Published: August 2022

The study examined the nexus between the overall cost of celebrity endorsement and market performance of alcoholic brewery products in Lagos Metropolis in Nigeria. The population of the study therefore was 1,184. The study adopted a census technique for this study. The reason behind this is to mitigate possible high rate of non-response during the survey. The study anticipated some level of non-response since the targeted products has capacity to intoxicate consumers. The study revealed that all the independent variables have a positive effect on product market performance, except cost of celebrity endorsement, with their respective coefficient values of 0.097984 for cost of celebrity advertising, 0.825558 for cost of celebrity selection process/audition, 0.363291 for cost of celebrity publicity and -0.385858 for cost of celebrity endorsement. While cost of celebrity selection process/audition exerts a positively significant effect on product market performance with 0.0370 probability value, the positive effects of cost of celebrity advertising and cost of celebrity publicity are not significant with their respective P-values of 0.4109 and 0.4625. Also, the negative effect of the cost of celebrity endorsement is insignificant with the probability of 0.5653. The study concluded the insignificant effect of cost of celebrity advertising and cost of celebrity publicity on product performance might be due to the failure of the firms in the Brewery industry to endorse celebrity that has the potentials to stimulate the buying behaviour of customers. The study further recommends that cost of advertising, cost of celebrity selection process/audition and cost of celebrity publicity should be accorded great attention in the whole process of celebrity endorsement. The amount to be expended should be given thorough evaluation in relation to the attributes of the celebrities.

A tracer study is required to determine how effectively a university has succeeded in terms of strengthening its students' abilities and preparing them for the workplace. This paper aimed to determine the employability of BSIT graduates from the academic years 2017-2019revealing their demographic profile, the relevance of the program to employability, analysis of variance on the relevance of skills, curricular structure, and competencies as perceived by the respondents, and recommendations for curricular enhancements to expand their competitiveness. The data was collected using a modified Graduate Tracer Study instrument, an informal interview was also conducted. The study employed a descriptive method. Frequency and percentages, weighted mean, and Anova were used to statistically treat data collected through a questionnaire created through Google forms from 52 respondents respectively. The findings revealed that the majority of the respondents came from batch 2018. Most of them are males, single and the age ranges from 20-24 years old. Likewise, the majority of the respondents were regularly employed and working full-time. The study further revealed that most of the graduate’s employment classification were Government Officials, IT clerk /Staff and IT Technical Support Specialist and Managing Proprietor or Supervisor under a private sector and the major line of Business were from IT, BPO/KPO, Academe and Small and Medium Enterprise. Moreover, the graduates also claimed that their skills, curricular structure, and competencies were very relevant to their present job and contributed greatly to their performance. Furthermore, the respondents perceived that there is a significant degree of variance among the 3 dimensions under the relevance of the program of study to the respondents’ employability. To further enhance the marketability of the BSIT program and the employability of the graduates, one of the recommendations is the periodic review of the curriculum by academic leaders, alumni, and industry representatives to guarantee that graduates have the knowledge and skills that are required in the sector.

Published: August 2022

The study investigated the performance of the students in Chemistry using computer-aided instruments using a quasi-experimental method with a pre-post-tests control group design. A total of one hundred ninety-one (191) grade 7 students were selected as respondents to the study. Students in the experimental group were exposed to computer-aided instruments, while students in the control group were exposed to traditional instructions. The findings reveal there was a highly significant difference between the performance of the experimental and that of the control group. Moreover, it is suggested not to use a single strategy, method, approach, or technique in delivering instruction to address the need of today’s mixed-ability classroom. It is recommended to include computer-aided instructions in the In-Service Training of the teachers and conduct a series of seminars on the different elements of this approach to have a deeper understanding and have a better idea of how computer-aided instruments are best used in the teaching and learning process.
