In modern-day knowledge and deeper understanding has an exceptionally important role in forming a student’s erudition. In order for a student to achieve a proper level of education the tutoring must be systematically based on gathering knowledge in an academic environment. Unfortunately the students may sometimes forget or misinterpret the gathered information. Geography is no exception. During the learning process of said subject, it is often observed, that some students cannot properly understand the new material, because the current level of knowledge is insufficient. Thus it is critical to find out the level of students understanding at the present and pinpoint the missing gaps in previously gathered information. The analysis of the survey showed a significant gap between the students of two classes. The students of grade II showed not only the better level of knowledge and understanding, but also were more motivated to learn, compared to grade I. By examining the result of the test regarding natural recourses, few questions revealed the flaws in geographical understanding. A meaningful amount of the students showed poor special understanding: were unable to name the leading countries regarding natural recourses extraction. The struggle to clearly reason the answer also became apparent: the lack of knowledge in the field of geographical theory and concepts is most noticeable. For both tested classes, the easiest questions were regarding the analysis of data, students successfully pointed out the classification of natural resources as well as the pros/cons of using fossil fuel. Keywords: geography teaching, geographical understanding, learning process.

Additive manufacturing processes offer high geometric flexibility and allow the use of new alloy concepts due to high cooling rates. For each new material, parameter studies have to be performed to find process parameters that minimize microstructural defects such as pores or cracks. In this paper, we present a system developed in Python for accelerated image analysis of optical microscopy images. Batch processing can be used to quickly analyze large image sets with respect to pore size distribution, defect type, contribution of defect type to total porosity, and shape accuracy of printed samples. The open-source software is independent of the microscope used and is freely available for use. This framework allows us to perform such an analysis on a circular area with a diameter of 5 mm within 10 s, allowing detailed process maps to be obtained for new materials within minutes after preparation.

Abstract BACKGROUND There is lack of information on the role of excitatory and inhibitory neurotransmitters in the development of seizures in patients with lower grade gliomas. Increase of glutamate and downregulation of GABA have been suggested in preclinical models and human surgical samples to be associated with brain tumor-related epilepsy. MATERIAL AND METHODS We prospectively investigated with the use of magnetic resonance spectroscopy (MRS) the differences in the ratio of metabolites (glutamate/GABA, glutamate/creatine and GABA/creatine) in the peritumoral areas between patients with or without seizures in a series of lower grade gliomas. Tumors were classified according to WHO Classification of 2016 as follows:11 grade II IDH mutated and 1p/19q codeleted; 3 grade III IDH mutated and 1p/19q codeleted; 6 grade II IDH mutated and 1p/19q intact; 1 grade III IDH mutated and 1p/19q intact; 1 grade II IDH wild-type. Patients received surgery alone or followed by temozolomide chemotherapy according to the presence of risk factors. RESULTS At baseline evaluation, maximum glutamate/GABA values were significantly higher (p=0.023) in the peritumoral area of patients with seizures (1.008 ± 0.368) with respect to those without seizures (0.691 ± 0.170). No other metabolites ratio showed significant differences between the two groups. Similar results were obtained when analyzing the metabolites ratio in the examinations during the follow-up. In the cohort of patients with seizures (n.14) variations of metabolite ratios were not associated with tumor location, 1p/19q codeletion, use of AEDs, concomitant chemotherapy or seizure characteristics (type, duration, frequency). CONCLUSIONS The study is ongoing with the aim of analyzing further the correlations between ratio of metabolites and status of the tumor (stable vs progressive).

The percentage of children with vitamin D deficiency in Poland is alarming. The aim of the study was to assess the knowledge about sources of food and the function of vitamin D, as well as the frequency of its supplementation. A survey was conducted among the parents of children from Central Poland attending primary schools, and a questionnaire containing mainly open-ended questions was used to collect the data. Most mothers knew at least one of the functions of vitamin D in the body but had a low level of knowledge about its dietary sources. Only a small group of respondents supplemented themselves and their children with vitamin D. Statistically significant influences on the level of knowledge about the functions and sources of vitamin D were place of residence (i.e., better knowledge in the countryside) and mothers’ level of education (i.e., the better educated, the greater knowledge). In the case of monthly income level, such impact was observed only in relation to the knowledge of vitamin D functions. Concerning the frequency of supplementation, only maternal level of education had a statistically significant effect (i.e., the higher the education level, the higher the frequency of supplementation). In addition, mothers who were aware of functions of vitamin D and nutritional sources, significantly more frequently supplemented vitamin D.

Abstract The use of edible flowers (EF) in gastronomy is gaining popularity; however, there is still a lack of information about the factors that most contribute to the acceptance of this product. Therefore, the objective of this study was to investigate the habits associated with the usage of EF in gastronomy in three different countries (Portugal, Slovenia, and Brazil) and also to evaluate the major determinants for those habits. In addition, the level of knowledge was also investigated, particularly with regard to the aspects such as perceived risks of toxicity and pesticides. For that, a questionnaire survey of self-response was carried out on a sample of 559 participants, from the above-mentioned countries. To analyse the data, basic descriptive statistical tools were used combined with crosstabs and chi-square tests. Finally, a tree classification was performed using the classification and regression trees algorithm. The results revealed that, regardless of the country, the participants were familiar with the use of EF in gastronomy. The participants had, in general, already consumed EF, and their use was more popular between the Portuguese participants, being the Brazilian those who used them less. Significant differences were found between the countries in the form of consumption of EF and also in the types of EF consumed. There were also significant differences regarding the reasons for eating EF. The classification analysis showed that the country and the level of education were the major determinants for the consuming habits and knowledge about EF. This study highlighted that eating habits are very dependent on the customs and traditions of each country and helped understanding the factors that most affect the participants’ attitudes towards the consumption and knowledge of EF.

The genus Panochthus represents the last lineage of "Panochthini" recorded in the Pleistocene. This genus has a wide latitudinal distribution in South America, and in Brazil it occurs in the southern and northeastern regions. In this paper we describe new material (isolated osteoderms and caudal tube fragments) assigned to Panochthus from the state of Rio Grande do Sul (southern Brazil) and discuss some taxonomic issues related to Panochthus tuberculatus and Panochthus greslebini based on this material . The occurrence of P. greslebini is the first for outside the Brazilian Intertropical Region. In addition, we describe new diagnostic features to differentiate the osteoderms of P. greslebini and P. tuberculatus. Unfortunately, it was not possible to identify some osteoderms at the species level. Interestingly, they showed four distinct morphotypes characterized by their external morphology, and thus were attributed to Panochthus sp. Lastly, we conclude that in addition to P.tuberculatus registered to southern Brazil, there is another species of the genus, assignable to P. cf. P. greslebini. Our analysis reinforce the reliability of caudal tube characters for the classification of species of Panochthus.

This article analyzes the behavioural changes in groups of consumers and households on the market with individual commodities, based on the classification of individual reasonable consumption. Consumers expressed the degree of influence in their decision-making on satisfying their needs through selected key marketing factors such as price, brand, quality, habits and experience, advertising, recommendation from friends and relatives, packaging, discounts, new items, and so on. The analysis sought to determine whether the changes in the economic situation in the Czech Republic have an impact on the degree of marketing instrument influence on consumer behavior and decision-making. To express the degree of influence 10 point opinion scale is used. Thanks to the investigation taking place in 2007 with 609 respondents and in 2013 with 516 respondents, it was possible, it was possible to deal with the search for evidence of differences in the importance of individual factors using the Wilcoxon test. In 2013, attention was also paid to the degree of influence of some marketing tools such as price, quality and discount events on consumer behavior and decision-making in selected groups of households created by different income levels and different level of education achieved by the head of the household. The influence is expressed by radial graphs.

Abstract Background: Brucellosis is an infectious zoonotic disease. In the Sub-Saharan Africa, where the prevalence of brucellosis is not clear and the disease has been reported in most parts of Africa including Eritrea. To this date, the level of knowledge and brucellosis status in the livestock owners’ of Northern Red Sea region, Eritrea, was unknown. Therefore, the objective of this study was to evaluate the level of knowledge and practice, and determine the prevalence of brucellosis in livestock owners in the Northern Red Sea region, Eritrea.Methods: It was a descriptive community-based cross-sectional study where villages and households were selected by simple random sampling and systematic random sampling respectively. A total of twenty-nine villages and 22 livestock owners from each village were selected randomly. Blood samples were screened using Rose Bengal plate test and positives further confirmed using competitive enzyme linked immunosorbent assay techniques. Predesigned structured questionnaire was used as data collection tool. A written informed consent was obtained from each study participants. Data were entered into CSPro and analyzed by SPSS software. Results were presented in percent and frequencies.Results: A total of 637 respondents were enrolled in the study with a mean age of 42.96. Respondents were dominated by males (74.9%) and Tigre (73%) in ethnicity. Majority of them were illiterate (55.5%) and 70.5% were farmers. The overall sero-prevalence of brucellosis in the selected community was found to be 1.8% with the highest prevalence in Gindae (3.9%) followed by Shieb (3.6%) subregion. The comprehensive good knowledge and practice was rated as 58.4% and 10.5% respectively. A significant association was also shown with age, ethnicity, religion, level of education, occupation and subregions of the respondents (p <0.001). Conclusion: The overall sero-prevalence of brucellosis in the livestock owners in the study region was generally low. However, they had lower level of knowledge and very poor practice. Their level of knowledge and practice showed significant association with their age, ethnicity, level of education and sub-regions. Increasing community awareness, introducing Brucella vaccination to animals and strict controlling of selling of unpasteurized milk to the consumers are highly recommended.

Purpose: Renal cell carcinoma (RCC) is the most common tumor of the kidney. Considering the TNM classification of 2009, locally advanced and metastatic diseases are included in the groups stage III and IV. The surgical treatment of these tumors could be divided into 3 categories: (1) curative (nephrectomy and/or metastasectomy), (2) cytoreductive, and (3) palliative. Targeted agents showed impressive antitumor efficacy and prolongation of progression-free survival. The integration between target therapy and surgery in patients with locally advanced or metastatic RCC has sometimes facilitated surgery. We aimed to evaluate patients’ response to tyrosine kinase inhibitor (TKI) therapy and the feasibility of surgery after that and to observe complications related to surgery. Methods: From February 2007 to September 2014 in the Istituto Tumori of Milan, IRCCS, we selected patients with locally advanced or metastatic diseases, treated with target therapy before surgery (which comprised nephrectomy or partial nephrectomy, cytoreductive surgery, and metastasectomy) and cryoablation. Results: We selected 33 patients who underwent surgery after TKI therapy. As for response to TKIs, 20 patients (60%) had stable disease, 9 patients (28%) had a partial response, and 4 patients (12%) had progressive disease. A total of 17 patients (51%) presented complications directly or indirectly related to surgery and most of those were classified as grade II Clavien-Dindo score. Conclusions: The association between TKI and surgery seems to have no contraindications. Our dataset provides an example of how surgery after TKI is possible in locally advanced metastatic tumor and does not have an excessive rate of postoperative complications.
