Nasal Secretions

Nasal smear is a valid method used to distinguish inflammatory and non-inflammatory conditions. The present study was conducted to evaluate the cytological picture and neutrophilic infiltration of nasal secretions of children from a primary school within Enugu metropolis in Enugu State, Nigeria. The study included 100 apparently normal pupils, 20 each from grade levels 1 to 5. The blow-out technique was used to obtain samples from the nasal cavity for smear preparation on slides. May-Grunwald-Giemsa was used to stain the smears for light microscopical examination. Smears were assessed for the presence of infiltrating inflammatory cells and a semi-quantitative grading of neutrophilic infiltration was conducted on each sample to indicate either absent, few, moderate or many. Mean age of participants is 6.25±0.44 years (range: 6–11 years). Results revealed that age and grade level of study had a strong association with the grade score of neutrophilic infiltration (p<0.05). Grade level 1 pupils, the youngest group (mean age: 6.25±0.44 years), had the highest abnormal cytological picture and neutrophilic infiltration while those in grade levels 3 to 5 who were older, were lower. There was no association between gender and neutrophilic infiltration. It can be concluded that significantly increased neutrophilic infiltration are obtained in the nasal secretions of younger schoolchildren below the age of 9 than the older pupils. This study also indicates that the blow-out method is a useful technique for obtaining nasal secretions for the assessment of infiltrating cells.

Realistic Images

The purpose of this study was to investigate how education majors' images of teaching, teachers, and children change before and after student teaching, with special attention to the grade level (Grades 1–2, 3–4, 5–6) taught by the student teachers at primary school in Japan. A total of 126 student teachers from an education faculty (49 men, 77 women) participated in this study using metaphorquestionnaires before and after student teaching. For images of teaching, responses to the factors Dull Event and Live Event changed, suggesting that students started to develop more positive, active, and clear images of teaching. For images of teachers, responses on the factor Performer changed, suggesting that students started to develop more active images of teachers. For images of children, responses on the factors Critic and Pure-minded Person changed, suggesting that student teachers started to develop more realistic images of children. However, grade level taught had no significant effect.

Images Of Scientists

<p style="text-align: justify;">Research on students’ perceptions of scientists is ongoing, starting with early research by Mead and Metraux in the 1950s and continuing in the present. Continued research interest in this area is likely due to scholarship suggesting adolescents’ impressions of scientists are sourced in-part from media, which influence their interests in science and identity in becoming a scientist. A significant source of images, in which adolescents (or middle school students) view science and scientists, is in their science textbooks. A qualitative content analysis explored images of scientists in three of the major U.S.-based middle grade science textbooks published in the new millennium: sixth grade biology, seventh grade earth science, and eighth grade physical science. The Draw A Scientist Test (DAST) Checklist was employed to assess scientists’ images and the stereotypes therein. From nine textbooks, 435 images of scientists were coded and analyzed by publisher and grade level / area by DAST constructs of appearance, location, careers, and scientific activities. Statistical analyses showed significant variances between grade levels and textbook publishers of scientists. Despite scientists portrayed in active endeavors, traditional tropes of the scowling, older, solitary, white male scientist persist. This study offers insight in leveraging improved images of scientists in textbooks.</p>

Abstract A translocator protein 18 kDa targeted radiotracer, N,N-diethyl-2-(2-(4-[18F]fluorophenyl)-5,7-dimethylpyrazolo[1,5-a] pyrimidin-3-yl) acetamide ([18F]FDPA), was automated synthetized and evaluated for cardiac inflammation imaging. Various reaction conditions for an automated synthesis were systematically optimized. MicroPET/CT imaging were performed on normal rats and rats with myocardial infarction (MI). Normalized SUV ratios of [18F]FDPA to [13N]NH3 (NSRs) in different regions were calculated to normalize the uptake of [18F]FDPA to perfusion. The amount of TBAOMs and the volume/proportion of water were crucial for synthesis. After optimization, the total synthesis time was 68 min. The non-decay corrected radiochemical yields (RCYs) and molar activities were 19.9 ± 1.7% and 169.7 ± 46.5 GBq/μmol, respectively. In normal rats, [18F]FDPA showed a high and stable cardiac uptake and fast clearance from other organs. In MI rats, NSRs in the peri-infarct and infarct regions, which were infiltrated with massive inflammatory cells revealed by pathology, were higher than that in the remote region (1.20 ± 0.01 and 1.08 ± 0.10 vs. 0.89 ± 0.05, respectively). [18F]FDPA was automated synthesized with high RCYs and molar activities. It showed a high uptake in inflammation regions and offered a wide time window for cardiac imaging, indicating it could be a potential cardiac inflammation imaging agent.

Breakfast Consumption

Background. The aim of this study was to examine the breakfast habits, nutritional status and their relationship with academic performance in primary school students in Tehran, Iran.Method. In this cross-sectional study 829 primary school children were included. Child Body Mass Index (BMI) was calculated based on the objective measures of height and weight as well as adjusted for age and gender. Data on Breakfast habits and academic performance were collected by a valid checklist. For data analysis we used Chi-squared and Fisher's exact test using SPSS software, version 11.5; statistical significance was assumed if p-value is below the 0.05Results. The average breakfast consumption per week was 5.5 times (days) with a standard deviation of 2.9. Based on the results, 30.9 % of participants did not consume full breakfast (six times or less) and 69.1 % had a complete one. In terms of academic grade level, 88.4 % of the participants were in a high level, 10.3 % in appropriate conditions and only 1.3 % of the respondents required more effort (inappropriate).There was no significant correlation between breakfast consumption and academic status (p=0.73), nutritional status of the participants according to the academic performance status Individuals showed no statistically significant relationship (P=0.9).Conclusion. Unlike previous studies, this study revealed no correlation between the academic grade level of elementary students with nutritional status and breakfast habits. It is suggested that according to the qualitative school scoring method, future studies are needed to assessing the students' academic performance. Other parameters will be considered in addition to the average in order to provide a better perspective of students' academic performance.

This study aims to investigate problem-solving with dataset (PSWD) as a computational thinking learning implementation as reflected in academic publications. Specifically, the purpose is to specify the scope of PSWD, which overlaps with the data literacy, thinking with data, big data literacy, and data-based thinking concepts in the literature. Subaims of the study are to identify the conceptual structure of PSWD based on definitions in academic publications and to classify the reasons given in the literature to show the need for PSWD. For the purposes to investigate PSWD conceptually, to classify the reasons given for the need for PSWD, the obtained 54 publications were analyzed via content analysis. Moreover, this study investigates the most frequently suggested or used teaching strategies (in terms of instructional methods, instructional tools, and grade level) for PSWD in the literature. The frequencies of used words in selected publications referring instructional methods, instructional tools, and grade levels were shown in the findings of study. The importance of the study stems from its focus on a new approach to computational thinking instructional implementation.

Grade Level Differences

The purpose of this study was to assess children's tolerance of specific problem behaviors and to determine if differences in grade levels existed. The Children's Tolerance Scale (CTS) was completed by 469 third to sixth graders. A one-way multivariate analysis of variance yielded significant grade level differences (p < .001), with older children generally the most tolerant. The more outer-directed behaviors (Negative Aggressive and Poor Peer Cooperation) were rated as most disturbing. Implications for mainstreaming behaviorally disordered students and future research are discussed.

Grade Reading Level

Waiver of liability forms should be written at a reading level consistent with that of the intended audience. On average, students read three grade levels below the last grade they completed in school. Therefore, waivers should be written no higher then the ninth-grade level. The main goal of this study was to assess the reading level of intramural and recreational sport waiver of liability forms, compared to the ninth-grade level. Nine NIRSA member schools and nine non-NIRSA member schools were randomly selected from each of NIRSA's six regions. Readability was assessed using the Readability Calculation software (Micro Power & Light, Dallas, TX) for MacIntosh. A one-sample t-test was performed to compare the forms to the ninth-grade reading level. Forms were written significantly higher than the ninth-grade level (t[26]=14.53, p<.0001). An analysis of variance was performed to assess possible moderating variables. No significant differences were found. Font size was also measured, and forms were found to have been written at a significantly higher level then the recommended 12-point font (t[28]=-2.88, p<.01). This study brings into question the efficacy of waiver of liability forms used in many collegiate/university intramural and recreational sports programs.

The purpose of this study was to investigate Turkish and American undergraduate students' academic motivation and academic self-concept scores regarding the years that they spent in university. The analysis was based on 566 (284 Turkish, 282 American) undergraduate students where, Academic Motivation Scale and Academic Self-Concept Scale were used as measuring instruments. The results showed that there was a statistical significant effect of nationality and number of years spent in university on undergraduate students' intrinsic motivation, extrinsic motivation, and self-concept scores. Turkish students had higher intrinsic scores whereas American students had higher extrinsic scores and more positive academic-self concept compared to Turkish partners. Regarding grade level, senior students from both cultures had higher intrinsic motivation and academic self-concept scores compared to other grade levels. In terms of extrinsic motivation, there is steady decline in American students' scores as grade level increases. On the other hand, Turkish undergraduates' extrinsic scores decrease in the second year but increase in the third and fourth year of university education. Results were discussed by taking into consideration the social and cultural differences between two nations.
