Association between the Anatomical Location of Glioblastoma and Its Evaluation with Clinical Considerations: A Systematic Review and Meta-Analysis.

Background: Glioblastoma is a primary malignant brain tumor; it is aggressive with a high degree of malignancy and unfavorable prognosis and is the most common type of malignant brain tumor. Glioblastomas can be located in the brain, cerebellum, brainstem, and spinal cord, originating from glial cells, particularly astrocytes. Methods: The databases MEDLINE, Scopus, Web of Science, Google Scholar, and CINAHL were researched up to January 2024. Two authors independently performed the search, study selection, and data extraction. Methodological quality was evaluated with an assurance tool for anatomical studies (AQUA). The statistical mean, standard deviation, and difference of means calculated with the Student's t-test for presence between hemispheres and presence in the frontal and temporal lobes were analyzed. Results: A total of 123 studies met the established selection criteria, with a total of 6224 patients. In relation to the mean, GBM between hemispheres had a mean of 33.36 (SD 58.00) in the right hemisphere and a mean of 34.70 (SD 65.07) in the left hemisphere, due to the difference in averages between hemispheres. There were no statistically significant differences, p = 0.35. For the comparison between the presence of GBM in the frontal lobe and the temporal lobe, there was a mean in the frontal lobe of 23.23 (SD 40.03), while in the temporal lobe, the mean was 22.05 (SD 43.50), and for the difference in means between the frontal lobe and the temporal lobe, there was no statistically significant difference for the presence of GBM, p = 0.178. Conclusions: We believe that before a treatment, it will always be correct to know where the GBM is located and how it behaves clinically, in order to generate correct conservative or surgical treatment guidelines for each patient. We believe that more detailed studies are also needed to show why GBM is associated more with some regions than others, despite the brain structure being homologous to other regions in which GMB occurs less frequently, which is why knowing its predominant presence in brain regions is very important.

Effect of talent development on organizational performance

The proliferation of public universities has intensified competition for talent acquisition, accentuating talent development's significance as a pivotal determinant of organizational efficacy. Concurrently, fiscal constraints, imposed by the Kenyan government, have imposed financial strains on public universities, potentially diverting attention away from talent development imperatives. Against this backdrop, this study aims to scrutinize the influence of talent development initiatives on the performance of Maasai Mara University. A total of 86 respondents were engaged in structured interviews, facilitated by standardized questionnaires to gather data pertinent to the research objectives. Participants were selected to ensure representativeness across various organizational hierarchies and departments using a stratified simple random sampling technique. Descriptive statistical methods, including mean and standard deviation calculations, were employed to summarize the data, while inferential analyses, such as Pearson correlation analysis and multiple linear regression, were conducted to ascertain the relationship between talent development and organizational performance. The findings of the study underscore the salience of talent development endeavors in bolstering organizational performance. Notably, the statistical analysis revealed a statistically significant relationship between talent development and organizational performance, as evidenced by an R2 change of 0.204, signifying that talent development accounted for 20.4 % of the variance in organizational performance. Consequently, the study advocates for implementing robust talent development strategies within public universities, positing them as catalysts for enhancing organizational effectiveness. This study's implications extend beyond academia's confines, offering actionable insights for policymakers and organizational leaders, tasked with charting talent management strategies. By informing policy formulation and strategic planning processes, the findings of this study are poised to contribute to the enhancement of talent management practices within the higher education sector, thereby fostering institutional resilience and efficacy

Elastic Properties of Low-Dimensional Single-Crystalline Dielectric Oxides through Controlled Large-Area Wrinkle Generation.

Freestanding single-crystalline SrTiO3 membranes, as high-κ dielectrics, hold significant promise as the gate dielectric in two-dimensional (2D) flexible electronics. Nevertheless, the mechanical properties of the SrTiO3 membranes, such as elasticity, remain a critical piece of the puzzle to adequately address the viability of their applications in flexible devices. Here, we report statistical analysis on plane-strain effective Young's modulus of large-area SrTiO3 membranes (5 × 5 mm2) over a series of thicknesses (from 6.5 to 32.2 nm), taking advantage of a highly efficient buckling-based method, which reveals its evident thickness-dependent behavior ranging from 46.01 to 227.17 GPa. Based on microscopic and theoretical results, we elucidate these thickness-dependent behaviors and statistical data deviation with a bilayer model, which consists of a surface layer and a bulk-like layer. The analytical results show that the ∼3.1 nm surface layer has a significant elastic softening compared to the bulk-like layer, while the extracted modulus of the bulk-like layer shows a variation of ∼40 GPa. This variation is considered as a combined contribution from oxygen deficiency presenting in SrTiO3 membranes, and the alignment between applied strain and the crystal orientation. Upon comparison of the extracted elastic properties and electrostatic control capability to those of other typical gate dielectrics, the superior performance of single-crystalline SrTiO3 membranes has been revealed in the context of flexible gate dielectrics, indicating the significant potential of their application in high-performance flexible 2D electronics.

Mathematical Software: A Panacea for Improving Senior Secondary School Students’ Retention in Geometrical Constructions

When attempting to address the persistently poor performance of students in mathematics, researchers have typically examined factors such as retention to identify long-term solutions. The objective of this study was to improve the retention of senior secondary school students in geometrical constructions through mathematical software. Despite the many benefits of geometry to both the learner and society, the performance of the students continued to be abysmal. Could it be that the students do not retain what they learn? The research was conducted in Benue State, Nigeria, and was based on John Sweller’s cognitive load theory of multimedia. The study’s design utilised a non-randomised, quasi-experimental control group with a sample size of 457 students. Three objectives, research questions and research hypotheses led the study, with the Geometrical Construction Achievement Test and the Geometrical Construction Retention Test as the instruments for data collection. The mean and standard deviation of descriptive statistics were used to analyse the data that was gathered. The research reveals that retention was higher in the experimental group (Mean = 65.88) than in the control group (Mean = 51.87). The study found a statistically significant improvement in retention (p ˂ 0.05). No gender variations were found when the students were taught with mathematical software. Mathematics teachers’ utilisation of mathematical software as a strategy for teaching geometrical constructions among senior secondary school students was recommended.

ACUTE MYOCARDIAL INFARCTION WITH “ST” SEGMENT ELEVATION IN SOUTHERN MARCHE: INTRA AND POST–HOSPITAL PROCESS INDICATORS IN THE APPLICATION OF THE UNIFIED PDTA “RETE STEMI” AST OF ASCOLI PICENO AND FERMO. LONGITUDINAL OBSERVATIONAL CLINICAL STUDY

Abstract Background SCAs (Acute Coronary Syndromes) are one of the most frequent cardiovascular diseases, among which STEMI is certainly the most relevant in terms of short and long–term prognosis. The latest ESC Guidelines about ACS–STEMI indicate some key elements in terms of diagnosis and treatment, from first contact to cardiological rehabilitation. Objective Detect the number of SCA–STEMIs managed in the AST of Ascoli Piceno, along with intra and post–hospital process indicators provided in the PDTA of the “RETE STEMI” issued by the Marche Region specifically in AST of Ascoli Piceno. MATERIALS & METHODS An observational, longitudinal, monocentric, not–for–profit clinical study without diagnostic–therapeutic interventions was designed. The data collection started on 01/11/2022 and ended on 30/06/2023, at “Madonna del Soccorso” Hospital of San Benedetto del Tronto and “Mazzoni” Hospital of Ascoli Piceno in Cardiological Intensive Care Units (UTIC). Useful data for this study were acquired every month, consulting the folders of each patient diagnosed with “SCA–STEMI”, and then, reported in an Excel sheet, they were processed with different mathematical and statistical functions, including frequency, percentage, arithmetic average and standard deviation, and later used to design tables and graphs. All the data have been aggregated in full compliance with current legislation on the protection of patient privacy. Results The most significant results are related to the time between the first medical contact and the’ starting of the PPCI procedure, with an average time detected of 110 minutes. Another very important result is the number of patients sent to a post–acute cardiological rehabilitation program (PCRP): from the present study it appears that only the 1% of the entire sample was sent to a PCRP. Finally, other indicators considered in relation to the PDTA appear to be in line with the current Guidelines. Conclusions The present study highlights the aspects of the STEMI PDTA of the Marche Region which could be improved, namely reducing FCM–Wire crossing time and sending patients to a cardiological rehabilitation program, also by implementing the figure of the nurse specialized in the critical and cardiological area.

This study explored the attitudes toward Caesarean Section (C-section) as a delivery option among pregnant women in Ogbomoso, Oyo State, utilizing a descriptive cross-sectional design. The target population comprised aged 18 to 45years who registered and are attending antenatal clinic of the hospital for their antenatal care services, estimated at approximately 900. The random sampling technique through ballot was employed in the study, and a sample size of 298 participants was selected for the study which was determined using th Fisher’s formula. Data collection was facilitated through a well-structured questionnaire, which boasted reliability coefficients of 0.73 for attitudes towards C-sections. Statistical analyses, including percentage, standard deviation, and Analysis of Variance (ANOVA), were conducted at a 0.05 alpha level. The study unveiled that 675 (67.5%) majority exhibited a generally positive attitude towards C-sections. Age groups 18-30 and 31-40 years showed similar attitudes, with a criterion mean of 2.55, indicating a broadly shared positive perspective across age groups. However, educational attainment and religious beliefs were found not to significantly influence attitudes towards C-sections [F(4,291) = 1.473, p>0.05 for education; F(3,292) = 1.936, p>0.05 for religion]. The study concluded that pregnant women in Ogbomoso have a generally positive attitude towards C-sections as a delivery option, with minor variations across different age groups but no significant differences based on educational attainment or religious affiliation. It is recommended that healthcare providers continue educational efforts to demystify C-sections, addressing specific misconceptions and cultural beliefs, and ensure equitable access to C-section information and services for pregnant women across all demographics in Ogbomoso.

Stability verification of quantum non-i.i.d. sources

We introduce the problem of stability verification of quantum sources which are non-i.i.d.. The problem consists in ascertaining whether a given quantum source is stable or not, in the sense that it produces always a desired quantum state or if it suffers deviations. Stability is a statistical notion related to the sparsity of errors. This problem is closely related to the problem of quantum verification first proposed by Pallister et al (2018 Phys. Rev. Lett. 120), however, it extends the notion of the original problem. We introduce a family of states that come from these non-i.i.d. sources which we call a Markov state. These sources are more versatile than the i.i.d. ones as they allow statistical deviations from the norm instead of the more coarse previous approach. We prove in theorem 1 that the Markov states are not well described with tensor products over a changing source. In theorem 2 we further provide a lower bound on the trace distance between two Markov states, or conversely, an upper bound on the fidelity between these states. This is a bound on the capacity of determining the stability property of the source, which shows that it is exponentially easier to ascertain this with respect to n, the number of outcomes from the source.

This research study was concerned with the effectiveness of Geometrical Instructional teaching strategy on Junior Secondary School Students’ achievement, gender and attitude in Plane geometry in Odeda Local Government, Ogun State, Nigeria. The research study compared the effect of using Geometrical Instructional Teaching Strategy(GITS) and the conventional teaching approach on the achievement, gender and attitude of Junior Secondary School Students in Plane Geometry. The research was a pre-test post-test quasi-experimental control group design. Four (4) Junior secondary schools were purposefully chosen because of the availability of computers in these schools. Stratified random sampling technique was used to select the sample of 240 students (120 males and 120 females) drawn from four schools within the local Government. Four intact classes were used by the researchers for both experimental and the control groups. The experimental group was taught using Geometrical Instructional Teaching strategy package while the control group was taught using conventional teaching approach method. The Geometry Achievement test (GAT) consisting of (15) multiple choice items with four options, and Attitude Inventory on Plane Geometry (IIPG) were administered to students as pre-test and post-test before and after the treatment. Data collected was analyzed using descriptive statistics of mean and standard deviation to answer the four (4) research questions while the hypotheses were tested using analysis of covariance(ANCOVA). Result of the study revealed that students taught plane geometry using Geometrical Instructional Teaching Strategy package achieved higher mean scores than those students taught using conventional method. The result also revealed non-significant difference in the mean achievement and the mean attitude scores of males and female’s students taught plane geometry using Geometrical Instructional package and those students taught using conventional method. Some recommendations were made among which are that mathematics teachers should include the use of Geometrical Instructional Teaching Strategy to teach plane geometry.

Analysis of EEG Signals Between Motor Imaginary Tasks and Rest Condition for Biometric Application

Biometric technology has gained immense popularity as an effective solution for enhancing cybersecurity, specifically in countering financial fraud and security threats. EEG-based authentication is unique among biometric authentication methods due to its unparalleled confidentiality and non-replicability. This study explores the feasibility of using motor imagery tasks and rest conditions for human authentication. Ten physically fit subjects, aged between 20 and 28 years, participated voluntarily in the study. The subjects perform imaginary tasks involving their left and right-hand movement. Each task lasted for two minutes, separated by a one-minute break, and EEG data were collected using the EPOC+ device, which features 14-channel electrodes. The sampling frequency was set at 128 Hz. To extract relevant frequency information, Butterworth bandpass filters were employed to extract the alpha (8-13Hz), beta (14-30Hz), and gamma (30-42Hz) frequency bands. Linear features, such as power spectral density (PSD), were obtained using the Welch Method and the Burg Method, while spectral entropy was used to extract non-linear features. Statistical features mean, median, standard deviation, minimum, and maximum were derived from the PSD, and spectral entropy was used as input for the classifiers. Multiple classifiers, including k-nearest neighbor (KNN), support vector machine (SVM), decision tree and Naive Bayes, were employed for the classification task. The Welch method combined with the support vector machine classifier achieved a higher classification accuracy of 96.83% for the beta waves from channels C3, C4, O1, and O2, corresponding to the frontal and occipital lobes. Interestingly, the rest conditions exhibited a higher classification accuracy of 96.83% compared to the motor-imagery tasks, which achieved 96.04%. The utilization of motor imagery tasks and rest conditions, along with the application of advanced classification techniques, holds promise for the development of robust and reliable biometric systems in cybersecurity.

Large deviations in statistics of the convex hull of passive and active particles: A theoretical study.

We investigate analytically the distribution tails of the area A and perimeter L of a convex hull for different types of planar random walks. For N noninteracting Brownian motions of duration T we find that the large-L and -A tails behave as P(L)∼e^{-b_{N}L^{2}/DT} and P(A)∼e^{-c_{N}A/DT}, while the small-L and -A tails behave as P(L)∼e^{-d_{N}DT/L^{2}} and P(A)∼e^{-e_{N}DT/A}, where D is the diffusion coefficient. We calculated all of the coefficients (b_{N},c_{N},d_{N},e_{N}) exactly. Strikingly, we find that b_{N} and c_{N} are independent of N for N≥3 and N≥4, respectively. We find that the large-L (A) tails are dominated by a single, most probable realization that attains the desired L (A). The left tails are dominated by the survival probability of the particles inside a circle of appropriate size. For active particles and at long times, we find that large-L and -A tails are given by P(L)∼e^{-TΨ_{N}^{per}(L/T)} and P(A)∼e^{-TΨ_{N}^{area}(sqrt[A]/T)}, respectively. We calculate the rate functions Ψ_{N} exactly and find that they exhibit multiple singularities. We interpret these as DPTs of first order. We extended several of these results to dimensions d>2. Our analytic predictions display excellent agreement with existing results that were obtained from extensive numerical simulations.

Teachers’ Perception on Personality Traits and Social skills Development of Persons with Disabilities

Persons with Disabilities have problem with the development of appropriate social skills. However, social skill is essential to initiate and maintain positive social relationship among all. Previous studies focused largely on enhancing other skills areas among persons with Disabilities while functional skills development is not well researched. This study therefore, investigated Teachers’ perspectives on personality traits and social skills development among persons with Disabilities in Ibadan. Bandura’s social learning theory formed the bases and framework for the study. Four schools were purposively selected for the study. Forty (40) persons with various fiorms of disabilities were the respondents. The instruments used were Pupils Social Development Checklist (r=0.80), Neuroticism Scale for Children (0.73) and Personality Inventory for Children (Extroversion) (0.73) Scales. Data were analyzed using the descriptive statistics of mean and standard deviations at 0.05 level of significance. There is a significant positive relationship between the social skills development of persons with disabilities and extraversion (r=.368, p (.019) <.05), but there was no significant relationship between social skills development of persons with disabilities and neuroticism (r=-.141, p (.386)>.05) respectively. It was therefore concluded that persons with disabilities are predisposed to display unacceptable social characteristics as a result of peculiar personality traits of an individual persons. It was therefore recommended that teachers and care givers of persons with disabilities should note and pay attention to the fact that most people behave the way they do simply because of their peculiar personality trait as there are significant impact of personality traits on social skills development.

ANALYSIS OF STUDENT'S LEARNING INDEPENDENCE IN DISTANCE LEARNING DURING THE PANDEMIC USING RASCH MODEL

Due to COVID-19 pandemic, the government needs to initiate new policies that support the transition from face-to-face to online learning. This study aimed to examine the impact of student independence on distance learning. The sample included 835 elementary, middle, and high school students in Bekasi City and Regency, selected using proportional cluster random sampling. The data were collected using a student learning independence questionnaire. Furthermore, the study used non-experimental quantitative design and analyzed data through the Rasch model. The WINSTEPS software helped determine the instrument validity and reliability. Moreover, students’ discipline in online learning was determined using descriptive statistics of mean and standard deviation and logit item value and individual scores. The scores were specifically used to assess their readiness based on gender, age, ethnicity, and field of study. The results showed that student independence was moderate at 69% based on government regulations on online learning patterns. This condition influences the' mentality of students and learning independence in a conducive environment.

Teachers’ Occupational Stress and Coping Mechanisms

Teachers often experience high levels of stress in their work, but they are equipped with effective coping mechanisms to navigate through it. This study aimed to explore the relationship between teachers' occupational stress and coping mechanisms in public elementary settings. It sought to assess occupational stress based on working, living, and subjectrelated conditions while also evaluating teachers' emotion-focused and problem-focused coping mechanisms. Additionally, it aimed to establish significant relationships between occupational stress and these coping mechanisms. A descriptive correlational involving 145 public elementary teachers in Opol-West District, Misamis Oriental, utilized universal sampling. The study utilized an adapted and modified instrument from Cayao and Arenga (2021) and achieved a reliable Cronbach alpha of 0.855 to validate the survey questionnaire. Statistical tools, including mean, standard deviation, and Pearson correlation coefficients, were employed to analyze the data. Results showed that teachers feel some stress in their living conditions, but report challenges bring extreme stress. They also have moderate stress from subject-related conditions. It was concluded that teachers wanting to grow professionally can occasionally add stress to their overall work pressure. It was recommended that, implement strategies for teachers by coming up with better ways to submit reports.
