Data only becomes useful information when it has been analysed and the information has been processed, analysed, and interpreted. Small datasets of 100 or less subjects can be analysed quickly by hand. Data analysis starts with one-, two-, and three-way tables with the analysed data then summarized as percentages, proportions, range, averages, median, and standard deviation. Correlation measures associations between two variables and multiple variables may need to be analysed using regression techniques. Age and sex standardization is usually needed when comparing survey or reported data from two or more different populations. Analysis using computer programmes, such as EpiInfo, is useful for surveys.

Background: The spheno‐occipital synchondrosis (SOS) is an important growth center which plays an important role in cranial base development and can define the final relation of SOS with the upper and lower jaws. The morphology and fusion degree of SOS varies in different ages among different populations. Objectives: Thus, the aim of this study was to evaluate the age and sex dependence of ossification of the spheno-occipital synchondrosis in the Iranian population using CBCT. Methods: This cross-sectional retrospective study was performed on 517 CBCT images of 6- to 18-year-old patients in Mashhad, Iran. Patients with obvious pathology or fractures were excluded from the study. The SOS ossification was classified into four stages from 0 to 3. Two independent observers scored the images. The ossification stage of the SOS was classified according to the age and sex of the patients. Kruskal-Wallis and Kendall’s tau-b used for statistical analysis. Results: In this study, 517 samples of 260 females (50.3%) and 257 males (49.7%) with a mean age of 12.03 ± 3.74 years were examined. A significant difference did not exist between males and females regarding their stage of SOS ossification, although males were younger at the SOS transitional stages of 0 to 1, and 1 to 2 compared to females. Also, the SOS starts the ossification process at the age of 11 in females and 10.8 in males. Conclusions: The present study showed in the mean age of 16.81 ± 1.12 years, most subjects were in developmental stage 3. Due to the fact that in developmental stage 3 SOS closes, there were no passive maxillary growth after this time. In none of the SOS stages, females and males differed significantly in mean age (P > 0.05). The age of the onset of SOS closure in females was 11 years and in males it was about 10.8 years.

This brief study investigates the development of fundamental frequency (FO) in pre-adolescent children as a function of age and sex. The children who took part in the study were divided into three age groups: 6, 8 and 10 years. Each group consisted of three males and three females. Each subject produced nine target phrases with [] in phrase-final position, which were elicited via a picture-naming task. FO was estimated for the nine target utterances and the following FO parameters were derived: mean FO for the whole phrase; FO range for the whole phrase; standard deviation values of FO for the whole phrase and mean FO for the phrase-final vowel [α:]. Results indicated that FO parameters generally decreased with age, and by age 10 years the males had lower values than the females for all four parameters. Results also indicated that the mean standard deviation of FO across the phrase was significantly higher for the females compared to that for the males.

Recent advances in small-angle scattering (SAS) experimental facilities and data analysis methods have prompted a dramatic increase in the number of users and of projects conducted, causing an upsurge in the number of objects studied, experimental data available and structural models generated. To organize the data and models and make them accessible to the community, the Task Forces on SAS and hybrid methods for the International Union of Crystallography and the Worldwide Protein Data Bank envisage developing a federated approach to SAS data and model archiving. Within the framework of this approach, the existing databases may exchange information and provide independent but synchronized entries to users. At present, ways of exchanging information between the various SAS databases are not established, leading to possible duplication and incompatibility of entries, and limiting the opportunities for data-driven research for SAS users. In this work, a solution is developed to resolve these issues and provide a universal exchange format for the community, based on the use of the widely adopted crystallographic information framework (CIF). The previous version of the sasCIF format, implemented as an extension of the core CIF dictionary, has been available since 2000 to facilitate SAS data exchange between laboratories. The sasCIF format has now been extended to describe comprehensively the necessary experimental information, results and models, including relevant metadata for SAS data analysis and for deposition into a database. Processing tools for these files (sasCIFtools) have been developed, and these are available both as standalone open-source programs and integrated into the SAS Biological Data Bank, allowing the export and import of data entries as sasCIF files. Software modules to save the relevant information directly from beamline data-processing pipelines in sasCIF format are also developed. This update of sasCIF and the relevant tools are an important step in the standardization of the way SAS data are presented and exchanged, to make the results easily accessible to users and to promote further the application of SAS in the structural biology community.

Purpose: This study aims to determine the role of big five personalities simultaneously and partially towards the tendency of hard adventure travelers. Research methodology: This study will also look at the five traits found in the big five personalities which tend to play a role in the hard adventure traveler. This research is a replication study of Kristin Scott and John C. Mowen with a quantitative approach involving 1,558 subjects with a purposive sampling technique. Big five personality was measured using the big five infentory scale, while the hard adventure type would be measured using a scale from Scott & Mowen. Data analysis of this study using multiple regression techniques. Results: The results showed that there is a role of big five personalities that is simultaneous towards traveler's hard adventure type of 7,6%, whereas partially openness, extraversion, and neuroticism trait had a role towards the type of hard adventure, where openness trait had the biggest role towards hard adventure type. Limitations: Based on the magnitude of the role generated in this study, there are still other factors that can influence traveler's decision making to choose the traveling type, so that these other factors are expected to explore more. Contribution: This research can be a reference in the development of tourist attraction marketing by taking into account visitors' personality types.
