The aim of this study is to find out the relevance of the competences worked on in the area of social science, specifically in the subjects of geography and history, through the perceptions of pupils in the 4th year of compulsory secondary education (ESO). In order to carry out the survey, a purposive sampling was carried out in which more than 1400 4th year ESO students (in Spain) participated. In addition, using a Likert-type scale of our own creation called Evaluation of the Perception of Social Science Competences (EPECOCISO) and following a design of quantitative methodology, an exploratory factor analysis was carried out with the analysis software SPSS through the descriptive process, which allowed us to select the three factors that make up the study. Subsequently, correlations were established between factors through Pearson’s test, and between the different variables that make up each one of them with the socio-demographic variables (distinguishing between ordinal and nominal variables) through the chi-square test of independence and Cramer’s V test (nominal), as well as the linearity test, Goodman’s gamma test, and the Kruskal (ordinal) test. Finally, one of the most important conclusions of this study is that the difficulties encountered by students in the acquisition of competences is conditioned by the development of the assessment processes that are carried out.

Positive occipital sharp transients of sleep (POSTS) and lambda waves have similar morphology and location. We studied a possible association between these 2 normal EEG patterns. We reviewed a series of consecutive unselected ambulatory EEGs during a 3-month period (October 16, 2017 to January 19, 2018) and identified records with POSTS and records with lambda waves. Statistical analysis was performed using a chi-square test. A total of 140 ambulatory EEGs were reviewed. Duration of EEGs ranged from 24 to 168 hours (mean 76 hours). The population was 34% males, with ages ranging from 3 to 93 years (mean 48 years). Of the 140 records, 30 were abnormal, including 20 with epileptiform abnormalities. A chi-square test for independence (with Yates continuity correction) indicated a significant association between POSTS and lambda waves, χ2(1, n = 140) = 69.208, p < .001, φ = 0.72. In addition, 100% of records with lambda waves had POSTS, and 72% of records with POSTS had lambda waves. There is a high association between lambda waves and POSTS. This suggests a strong similarity between the 2 waveforms, and possibly a common occipital generator.

Abstract Objective: To estimate the prevalence of back pain in adolescent girls, and determine whether this pain is associated with socioeconomic, demographic, anthropometric, and behavioral factors. Methods: This was an epidemiological survey with a representative sample of 495 female high school students, aged 14 to 18 years, in the municipality of São Leopoldo in the southern Brazilian state of Rio Grande do Sul. Data were collected through a self-administered questionnaire with closed, standardized, coded, and tested questions. Bivariate analysis included the chi-square test (x2) and calculation of prevalence ratios (α<0.05). Results: The prevalence of back pain was 75.2%. The thoracic-lumbar (30.4%) and lumbar (27.7%) regions of the spine were most affected. Among the students with pain, 60.5% reported the severity of their pain to be moderate to severe, and 21.2% reported that the pain prevented them from performing activities of daily living. Regarding associated factors, the pain was more prevalent in overweight/obese students (RP = 1.246, 95% CI: 1.137 to 1.366), who reported carrying a heavy school backpack/bag (PR = 1.187, 95% CI: 1.073 to 1.314) and those who had incorrect posture when picking up objects from the floor (PR = 1.138, 95% CI: 1.031 to 1.256). Conclusions: There was a high prevalence of back pain associated with body mass index, reported weight of the student's school backpack/bag, and posture when picking up objects from the floor.

Currently, during the pandemic, the forced transition to distance learning carries a number of problems. These problems affect various aspects of education, including the study of students’ attitudes to distance learning. The purpose of this research is to study the features of the subjective attitude of schoolchildren and students to distance learning. This research involved 140 secondary school students (average age M = 10.7, SD = 7.2 (66.3% men)) and 30 university students (average age M = 22.5, SD = 2.4 (20% men)). The methods used were a questionnaire, Chi-square test and Criterion φ*. Fisher angular transformation. The study showed that schoolchildren do not intend to continue studying in the distance form if they choose, with a generally positive attitude towards distance learning. The self-assessment of motivation to study in a distance format has not changed, both among schoolchildren and students. Students are more likely to have a positive attitude to distance learning than schoolchildren. The variety of choices of advantages and disadvantages of distance learning is greater among students than among schoolchildren. The perspective of this study is thus to study the factors that determine the positive and negative attitudes to distance learning.

Nowadays, drugs (narcotics, psychotropic, and addictive substances) abuse gradually increases in the adolescent group, especially High School students. Environmental impact, especially social interaction, gives a high effect on building the character in adolescents. The existence of peer-education activity is one of the promotive and preventive strategies in mitigating drug abuse. This research was done in 10 high schools in Surabaya spread over five regions (Central, North, South, West, and East). This research was quantitative with the cross-sectional design while the data analysis used was a Chi-Square test with a p-value of <0.05 that was based on the significance level. The research finding showed that the intention of student participation was quite high, i.e. 83.1%; from the statistical test, it had been taught that gender had a significant relationship with intention by a p-value of 0.00. Additionally, it had also a relationship with subjective norm by a p-value of 0.00.  Conclusion: the student’s norm has supported their intention to participate in the program. Meanwhile, the research finding that is based on the gender in this research showed that females had a higher intention to participate in the activity than the males had.  Therefore, a conducive environment should be maintained continuously so that the positive norm can motivate the students to participate in the activity held by the peer-educator.

Abstract The purpose of this study was to assess the level of digitization of Educational Technology Centres for teaching electrical and electronics technology in Colleges of Education in North Eastern Nigeria in order to provide information that will help solve problems of incompetence of public school students in Information and Communication Technology (ICT). The study, guided by two research questions and two hypotheses was conducted in six Colleges of Education in North Eastern Nigeria using descriptive survey research design. The sample of the study was 50 comprising of 15 non-teaching Educational Technology Centres staff and 35 Electrical and Electronics Technology lecturers from five colleges of education in North Eastern Nigeria. Checklist containing 103 expected digital facilities based on National Commission for Colleges of Education (NCCE) minimum standard for Educational Technology Facilities in Colleges of Education in North Eastern Nigeria was used as instrument for data collection. Respondents were required to fill in observed facilities in the required column. Arithmetic percentage and Chi–square test of goodness-of-fit and were used determine the extent of digitization of the Educational Technology Centres in Colleges of Education in North Eastern Nigeria. Findings of the study revealed among others that analog technologies has higher number of frequency counts compared to digital technologies, hence there was low digitization of hardware facilities in Educational Technology Centres in Colleges of Education in North Eastern Nigeria. The study therefore concluded that Educational Technology Centres in Colleges of Education in North Eastern Nigeria were not digitized for instructional purposes; therefore, Government should digitize Educational Technology Centres in Colleges of Education in North Eastern Nigeria by adequately providing both digital hard and soft ware facilities.

Objective: To determine the prevalence and distribution of premature eruption and agenesis of premolars in a sample of Turkish children. Study design: A sample of 1715 patients aged 5 to 11 years was selected. Panoramic radiographs were used to assess premature eruption and agenesis of premolars. Developmental stage of erupted premolars was assessed using Demirjian’s method and selecting prematurely erupted premolars on the basis of clinical eruption with a root length less than half of their final expected root lengths. Statistical analysis was performed using chi-square test (p &lt;.05). Results: One hundred fifteen (6.7%) of 1715 patients presented at least one premolar agenesis with no significant sex difference (56 boys, 59 girls). Mandibular second premolars were the most absent teeth. Multiple agenesis of premolars (3.4%) was more common than single agenesis (3.3%). A total of 85 (5.0%) patients (51 boys, 34 girls; no significant sex difference) had at least one prematurely erupted premolar, and maxillary first premolars were most commonly affected. Early erupted premolars were in stage D or E based on Demirjian’s dental formation scale. Conclusions: The prevalence of premature eruption and agenesis of premolars in Turkish children were 5.0% and 6.7%, respectively. Both conditions are not uncommon and may highlight the need for early diagnosis to prevent subsequent clinical problems.

Seasonality Of Births

SummarySeasonal variation in the births of patients with schizophrenia is a consistently replicated epidemiological finding. Few studies have investigated this phenomenon among patients with a diagnosis of affective disorder. The majority of season of birth studies have employed the chi square test for statistical analysis, a method that has been subject to some criticism. Using a Kolgomorov-Smirnov type statistic, the quarterly birth distribution of 6,646 patients with an ICD 9/10 diagnosis of affective disorder were compared to the general population. Only the births of those individuals with unipolar forms of affective disorder (n = 4,393) differed significantly from the general population, with significant excesses and deficits in the second quarter and fourth quarter respectively. These results were not altered by application of the displacement test. © 1998 Elsevier, Paris
