The Analysis of the Nutritional Status and Dietary Habits among Children Aged 6–10 Years Old Attending Primary Schools in Poland

A high prevalence of obesity among children is influenced by serious implications. Obesity mainly results from behavioral factors, such as improper dietary habits. This study aims to evaluate the nutritional status and dietary habits of children aged 6–10 (n = 908) attending primary schools in Poland, Europe. The research tool was a questionnaire that was completed by one of the children’s parents. A statistical analysis was made using statistical software. The value of p = 0.05 was considered to be statistically significant. A total of 74.7% of children surveyed have a normal body mass. As many as 91.7% and 76.6% of children, respectively, eat a first and second breakfast daily. Nearly half of parents (48.9%) state that their child consumes milk or other dairy products daily. A total of 74.3% of children drink water daily. A total of 27.6% eats fish less frequently than once a week. A total of 7.6% of children eat fish several times a week. As many as 20.6% of the respondents state that their child eats brown bread several times a week, whereas 19.9% state that their child never eats brown bread. A total of 55.1% of children eat fruits and/or vegetables daily. A total of 14.1% of children surveyed consume sweets daily. The study revealed a positive correlation between BMI and the frequency of mineral water consumption (p = 0.013) in 9 y.o. girls. It was also revealed that the number of consumed fruit/vegetables increases with the BMI value among 10 y.o. boys (p = 0.044). Conclusions: The dietary habits of the investigated children are still improper. There is a great need for education on this issue, but family involvement is also required.

Elevated P-Element-Induced Wimpy-Testis-Like Protein 1 Expression Predicts Unfavorable Prognosis for Patients with Various Cancers

Increasing evidence has shown that overexpression of P-element-induced wimpy-testis (PIWI)-like protein 1 (PIWIL1) was associated with unfavorable prognosis of patients with various types of cancers. Herein, we conducted this meta-analysis to identify the clinicopathological and prognostic value of the PIWIL1 expression in cancers. Three electronic databases (PubMed, Web of Science, and Embase) were comprehensively retrieved for relevant studies up to August 4th, 2019. RevMan 5.3 and STATA 12.0 statistical software programs were used to explore the relationships between PIWIL1 expression and the prognosis and clinicopathological features in cancer patients. A total of 13 studies recruiting 2179 patients with 9 types of solid tumors were finally included in the meta-analysis. The results indicated that patients with high PIWIL1 expression tended to have a shorter survival, and additionally deeper tumor invasion, higher clinical stage, and more lymph node metastasis. PIWIL1 could serve as a biomarker for prognosis and clinicopathological characteristics in various cancers.

STATISTICAL SOFTWARE R IN CORPUS-DRIVEN RESEARCH AND MACHINE LEARNING

The rapid development of computer software and network technologies has facilitated the intensive application of specialized statistical software not only in the traditional information technology spheres (i.e., statistics, engineering, artificial intelligence) but also in linguistics. The statistical software R is one of the most popular analytical tools for statistical processing a huge array of digitalized language data, especially in quantitative corpus linguistic studies of Western Europe and North America. This article discusses the functionality of the software package R, focusing on its advantages in performing complex statistical analyses of linguistic data in corpus-driven studies and creating linguistic classifiers in machine learning. With this in mind, a three-stage strategy of computer-statistical analysis of linguistic corpus data is elaborated: 1) data processing and preparing to be subjected to a statistical procedure, 2) utilizing statistical hypothesis testing methods (MANOVA, ANOVA) and the Tukey post-hoc test, and 3) developing a model of a linguistic classifier and analyzing its effectiveness. The strategy is implemented on 11 000 tokens of English detached nonfinite constructions with an explicit subject extracted from the BNC-BYU corpus. The statistical analysis indicates significant differences in the realization of the factors of the parameter “Part of speech of the subject”. The analyzed linguistic data are employed to build a machine model for the classification of the given constructions. Particular attention is devoted to the methodological perspectives of interdisciplinary research in the fields of linguistics and computer studies. The potential application of the elaborated case study in training undergraduate, master, and postgraduate students of Applied Linguistics is indicated. The article provides all the statistical data and codes written in the R script with comprehensive descriptions and explanations. The concluding part of the article summarizes the obtained results and highlights the issues for further research connected with the popularization of the statistical software complex R and raising the awareness of specialists in this statistical analysis system.

Gender Was Associated with Depression but Not with Gastrointestinal Dysfunction in Patients with Parkinson’s Disease

Objective. To investigate the association between gender and gastrointestinal (GI) dysfunctions, as well as gender and other motor symptoms/nonmotor symptoms, in a sample of PD patients. Methods. 186 patients with PD were recruited into this study and divided into male PD group (M-PD) and female PD group (FM-PD). Demographic and PD-related clinical information of the participants were collected by the same neurologist. PD patients were objectively assessed by a spectrum of rating scales of motor symptoms and nonmotor symptoms (including GI dysfunctions). The data were analyzed by SPSS 20 statistical software. Results. Totally 95 cases (51.08%) were in the M-PD group and 91 cases (48.92%) in the FM-PD group. There were no significant differences in age, BMI, and lifestyles between the two groups (P > 0.05). Males had higher educational level (P = 0.002). Females were more likely to have early satiety and loss of appetite (P = 0.025, P = 0.001). There were no significant differences in LED disease duration, age of motor symptoms onset, types of motor symptoms onset, location of motor symptoms onset, and phenotype of motor symptoms between the two groups (P > 0.05). Females had significantly higher UPDRS-III and HAMD scores than males (P = 0.037, P = 0.034). There were no significant differences in PQSI, ESS, RLS, RBD, HAMA, HAMD, and MoCA scores between the two groups. Gender was associated with HAMD (OR = 0.682, P = 0.019). Conclusions. Gender is a risk factor for depression, but not for GI dysfunctions in patients with PD.

The impact of social media activities on raising brand awareness during the COVID-19 pandemic

The aim of this research is to identify social media activities that affect the increase of brand awareness in the fashion industry in Kosovo. The research considers five different social media activities (advertising, influencers, sharing, entertainment, and interaction), and to the best knowledge of the authors, this is the first experiment to consider these factors all together, as well as the first one addressing brand awareness in Kosovo. Quantitative methods were used on a sample of 224 respondents, including confirmatory factor analysis and regression analysis. The analysis was conducted by using the AMOS statistical software. The findings indicate that activities, such as interaction and advertising, have a significant impact on brand awareness, unlike entertainment, sharing, and influencers’ behaviour. The findings provide marketers with recommendations regarding social media activities and the challenges that must be considered before they are implemented.

Statistics Teaching Practice at Czech Universities with Emphasis on Statistical Software

This paper aims to reveal the beliefs of students and fresh university graduates about teaching statistics during their university studies with focus on using statistical software. The objective is to detect the approach of faculties to statistics education and to find out which didactic materials and teaching methods are mainly used. Students’ opinions are captured by means of a questionnaire survey and analysed both quantitatively and qualitatively. The results show the increasing importance of quantitative research and the necessity of improving statistical thinking. Unfortunately, the teaching methods used in various statistical courses are outdated and unattractive for most students. They call for an active and modern approach. Teaching statistics with the statistical software support seems to be the right way to make statistics accessible to students. The recommendation is to take students’ notions into account when preparing statistical courses.

Perfectionism, Mood States, and Choking in Asian University Baseball Players under Pressure during a Game

The purpose of this study was to investigate relationships among mood states, perfectionism, and choking, and to identify a mediating effect of perfectionism on the relationship between mood states and choking experienced by Asian university baseball players in extremely stressful situations during a game. Data collected from a total of 209 male university baseball players were analyzed using SPSS 21 and AMOS 21 statistical software. The mean age of study subjects was 20.25 years. Results are as follows. First, mood states had a positive influence on perfectionism. Second, mood states had no significant influence on choking. Third, perfectionism had a positive influence on choking. Lastly, perfectionism had a complete mediating effect on the relationship between mood states and choking. The study findings will provide basic data to relieve athletes’ psychological burdens, and prevent manifestations of extreme perfectionism and choking, which can ultimately help athletes maintain high self-control of their mood states and perfectionism for better performance.
