The present work is focused on proposing the incorporation of Emerging Technologies (ET) in the Economic-Administrative area (EAA), specifically for students of the Bachelor's Degree in Accounting (LCN, Spanish acronym) and the Bachelor's Degree in Administrative Informatics (LIA, Spanish acronym), of the Chalco Valley University Center of the UAEMex, because they are focused on the development and creation of businesses, starting with the use of mobile phones, augmented reality and virtual supports. An instrument with a Likert scale elaborated, applied to a sample of 238 students of LIA and LCN, taking the total of students as population (408) and a convenience sampling was carried out. Also, there was an interview with 12 professors of both bachelor's degrees. The focus considered in the research was qualitative, transversal, and field. The questionnaire validated with Cronbach's alpha (0.81) and its score applying the mean and standard deviation, coding each of the items according to the characteristics of the study population. Among the results, teachers agreed to incorporate emerging technologies and to design how they will implement them in the classroom so that the proposed strategies contribute to the learning of students in the economic-administrative area.

Aims: To investigate whether karyotype, mid-childhood (6–10 years) follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, and ultrasound ovary visualization results can be used as indicators of spontaneous puberty in Turner syndrome (TS). Methods: The analysis was based on clinical and biochemical data from 110 TS girls aged >13 years at the end of the study (1,140 visits between 1996 and 2015). The study population was divided according to karyotype: 45,X and non-45,X. Results: The mean age ± standard deviation at diagnosis was 10.7 ± 4.0 years, and the follow-up duration was 5.9 ± 3.3 years. Spontaneous puberty was confirmed in 48% and menarche in 20% of the subjects, less frequently in 45,X girls. The mean age at Tanner stage B2 was 13.7 ± 2.4 years and that at menarche 14.2 ± 1.7 years, regardless of the karyotype. The median FSH level at 6–10 years was 8.16 IU/L, which was significantly lower than <6 years and >10 years. The median LH level at 6–10 years was 0.35 IU/L, which was lower than >10 years. The chance of spontaneous menarche was decreased in girls with FSH ≥6.7 IU/L between 6 and 10 years. Conclusions: Although spontaneous puberty and menarche occur more frequently in non-45,X girls, the karyotype cannot be used to predict them. However, the chance of spontaneous menarche can be predicted based on gonadotropin cut-off values. There was no correlation between ultrasound ovary visualization results and spontaneous puberty.

This study aimed to evaluate the polypharmacy extent and the frequency and severity of drug interactions by evaluating inpatients in the emergency department. In this epidemiologicaldescriptive study, data were collected retrospectively by reviewing medical records of 92 hospitalized patients in the emergency department with a stay over 48 hours. Out of the study population, 54.3% and 45.7% were respectively male and female, with a mean age of 59.09. In terms of hospitalization, 27.2% and 16.3% were hospitalized due to heart problems and trauma, respectively and the mean length of hospitalization was 3.91 with a standard deviation of 2.57 days. The mean drug received was 8.48, with a standard deviation of 4.48. Of the patients, 81.5% received more than 5 drugs; in addition, the observed amounts of drug interactions of A, B, C, D, and X were 2.5%, 17%, 59.3%, 19.5%, and 1.9%, respectively. The drug interaction prevalence in inpatients in the emergency department was high. The presence of a pharmacist is necessary to identify drug interactions and reduce drug-therapy problems to provide quality services.

Introduction: The bifurcation of trachea into two primary bronchi at the level of fourth thoracic vertebra creates an angle at the bifurcation. This angle can be seen clearly in routine chest X-rays where the measurement can throw light on many medical conditions within the mediastinum. This study aimed at finding the subcarinal angle, which is the angle formed by inferior borders of two primary bronchi. Methods: The measurements were taken from photographs of tracheal specimen of 92 cadavers, 63 male and 29 female. Angle was measured by photographic software and analysis of subcarinal angle was done in the study population. Results: The mean subcarinal angle was found to be 41.09° with standard deviation of 17.14°. This measurement was found to be significantly more in males (68.02± 15.72°) than in females (60.14 ± 17.71°). Conclusion: The subcarinal angles in the study population were seen to be different among sexes. Also, the mean subcarinal angles from other studies, radiological or on specimen were close to the observations made in this study.

SummaryThe characteristics of experimental error in measurement of platelet radioactivity have been explored by blind replicate determinations on specimens taken on several days on each of three Walker hounds.Analysis suggests that it is not unreasonable to suppose that error for each sample is normally distributed ; and while there is evidence that the variance is heterogeneous, no systematic relationship has been discovered between the mean and the standard deviation of the determinations on individual samples. Thus, since it would be impracticable for investigators to do replicate determinations as a routine, no improvement over simple unweighted least squares estimation on untransformed data suggests itself.

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.

1. The responses of neurons in the ventral cochlear nucleus (VCN) of decerebrate cats are described with regard to their regularity of discharge and latency. Regularity is measured by estimating the mean and standard deviation of interspike intervals as a function of time during responses to short tone bursts (25 ms). This method extends the usual interspike-interval analysis based on interval histograms by allowing the study of temporal changes in regularity during transient responses. The coefficient of variation (CV), equal to the ratio of standard deviation to mean interspike interval, is used as a measure of irregularity. Latency is measured as the mean and standard deviation of the latency of the first spike in response to short tone bursts, with 1.6-ms rise times. 2. The regularity and latency properties of the usual PST histogram response types are shown. Five major PST response type classes are used: chopper, primary-like, onset, onset-C, and unusual. The presence of a prepotential in a unit's action potentials is also noted; a prepotential implies that the unit is recorded from a bushy cell. 3. Units with chopper PST histograms give the most regular discharge. Three varieties of choppers are found. Chop-S units (regular choppers) have CVs less than 0.35 that are approximately constant during the response; chop-S units show no adaptation of instantaneous rate, as measured by the inverse of the mean interspike interval. Chop-T units have CVs greater than 0.35, show an increase in irregularity during the response and show substantial rate adaptation. Chop-U units have CVs greater than 0.35, show a decrease in irregularity during the response, and show a variety of rate adaptation behaviors, including negative adaptation (an increase in rate during a short-tone response). Irregular choppers (chop-T and chop-U units) rarely have CVs greater than 0.5. Choppers have the longest latencies of VCN units; all three groups have mean latencies at least 1 ms longer than the shortest auditory nerve (AN) fiber mean latencies. 4. Chopper units are recorded from stellate cells in VCN (35, 42). Our results for chopper units suggest a model for stellate cells in which a regularly firing action potential generator is driven by the summation of the AN inputs to the cell, where the summation is low-pass filtered by the membrane capacitance of the cell.(ABSTRACT TRUNCATED AT 400 WORDS)
