There is no question that business, education, and all fields of science have come to rely heavily on the computer. This dependence has become so great that it is no longer possible to understand social and health science research without substantial knowledge of statistics and without at least some rudimentary understanding of statistical software. The number and types of statistical software packages that are available continue to grow each year. In this paper we have chosen to work with SPSS, or the Statistical Package for the Social Sciences. SPSS was chosen because of its popularity within both academic and business circles, making it the most widely used package of its type. SPSS is also a versatile package that allows many different types of analyses. transformations, and forms of output - in short, it will more than adequately serve our purposes. The SPSS software package is continually being updated and improved, and so with each major revision comes a new version of that package. In this paper, we will describe and use the most recent version of SPSS, called SPSS for Windows, in order to use this text for data analysis, your must have access to the SPSS for Windows software package.The capability of SPSS is truly astounding. The package enables you to obtain statistics ranging from simple descriptive numbers to complex analyses of multivariate matrices. You can plot the data in histograms, scatterplots, and other ways. You can combine files, split files, and sort files. You can modify existing variables and create new ones. In short, you can do just about anything you'd ever want with a set of data using this software package. A number of specific SPSS procedures are relevant to the kinds of statistical analyses covered in an introductory level statistics or research methods course typically found in the social and health sciences, natural sciences, or business. Yet, we will touch on just a fraction of the many things that SPSS can do. Our aim is to help то become familiar with SPSS, and we hope that this introduction will both reinforce our understanding of statistics and lead us to see what a powerful tool SPSS is, how it can actually help you better understand your data, how it can enable you to test hypotheses that were once too difficult to consider, and how it can save our incredible amounts of time as well as reduce the likelihood of making errors in data analyses. We show how to create a data file and generate an output file. We also discuss how to name and save the different types of files created in the three main SPSS windows. This paper will present a software presentation from a survey on socio-economic and environmental research.

An increasing number of businesses now rely on computer technology to complete tasks. For this reason, possessing computer skills has become increasingly crucial This study aimed to assess the computer and ICT skills of employees in small-scale business organizations. The researcher administered a survey questionnaire to a purposive sample of 28 employees from small-scale business organizations, and the quantitative data gathered was organized and processed using SPSS version 17.0. The explanatory design employed unstructured interviews with non-probability sampled respondents to collect qualitative data. Thematic analysis was used to establish themes arising from the qualitative responses. Findings revealed that employees in these organizations have a low level of competence in performing office tasks, such as basic computer operations, file management, word processing, database use, and network use. There are no significant differences in computer and ICT skill levels among employees in small-scale business organizations when grouped by educational attainment, length of service, and gender. Based on the interviewees' responses, common themes emerged, such as poor internet connectivity, an unreliable power supply, a lack of funds to purchase gadgets that can access the internet, a lack of knowledge and interest in learning, and a lack of time to attend a short program related to computers and ICT are the reasons for low levels of computer and ICT skills. Tutorials and self-study are common strategies employees use to accomplish assigned tasks in the office.

Abstract This article details the novel structure developed to handle, harmonize and document big data for reuse and long-term preservation. ‘The Longitudinal IntermediaPlus (2014–2016)’ big data dataset is uniquely rich: it covers an array of German online media extendable to cross-media channels and user information. The metadata file for this dataset, and its documentation, were recently deposited as its own MySQL database called charmstana_sample_14-16.sql (https://data.gesis.org/sharing/#!Detail/10.7802/2030) (cs16) and is suitable for generating descriptive statistics. Analogous to the ‘Data View’ in spss, the charmstana_analysis (ca) contains the dataset’s numerical values. Both the cs16 and ca MySQL files are needed to conduct analysis on the full database. The research challenge was to process large-scaled datasets into one longitudinal, big-data data source suitable for academic research, and according to fair principles. The authors review four methodological recommendations that can serve as a framework for solving big-data structuring challenges, using the harmonization software CharmStats.

Full textAbstract:
Improvements in the thermomechanical processing procedures of NiTi wires have led to the development of new NiTi instruments that compose mainly of martensite crystals, making the wire stable at clinical condition. This study aimed at comparing the shaping ability of two rotary nickel-titanium systems manufactured from different NiTi wires. Twenty simulated root canals each with a curvature of 35° in resin blocks were divided into two groups of 10 canals each. Canals in the first group were prepared with superelastic F360 instruments (Gebr. Brasseler, Germany) while canals in the second group were prepared using controlled memory HyFlex®CM™ instruments (Coltène Whaledent, Switzerland). Images were taken before canal preparation and after the use of each instrument. The assessment of the canal shapes was accomplished with a computer image analysis program. Data were statistically analyzed using SPSS program. Within the limitation of this in vitro study, HyFlex®CM™ instruments remained better centered in the apical third of the canals. In most canal segments, no significant differences were observed between either system in the amount of material removed. Both systems were comparable to each other in regards to their ability to enlarge root canal in the same way without procedural errors.

Full textAbstract:
Aim: The aim of this study was to compare the accuracy of two different electronic apex locators (EALs) in detecting simulated incomplete vertical root fractures (VRFs). Materials and Methods: Thirty freshly extracted single-rooted teeth were randomly divided into three groups of 10 teeth each labeled as Groups A, B, and C. Incomplete VRFs were simulated in the coronal, middle, and apical one-third of the roots for Groups A, B, and C, respectively. The teeth were embedded in alginate mold and fracture location was determined with Root ZX and Propex EALs for each sample and each group. To calculate the actual length (AL), each sample was sectioned at the upper level of the vertical fracture, and the length was measured by setting the stopper of the #10 K file under a stereomicroscope at ×30 magnification. The electronic lengths and ALs were compared using computer software, and the results were analyzed using SPSS 28.0 at a 95% confidence level. Results: No significant differences were seen in the accuracy of the two EALs when compared with ALs. Root ZX showed significantly longer measurements than ALs in groups B and C. Conclusion: The tested EALs showed low accuracy (20%) in detecting simulated incomplete VRFs with a tendency for longer measurements compared to ALs.

Full textAbstract:
This study aims to develop a diagnostic tool to measure the information and communications technology (ICT) literacy capabilities of college freshmen. In the increasing dependence of ICT on teaching and learning, the diagnostic tool will help in operating software education for all freshmen, especially non-majors. To develop the diagnostic tool, ICT literacy competency diagnosis area and subattributes were defined through domestic and international literature study and empirical research. Moreover, diagnostic questions for the sub-attributes were developed. To validate the diagnostic tool, content validity was analyzed twice by experts, and a preliminary survey was conducted on freshmen from different departments. Through a preliminary survey, a diagnostic tool of ICT literacy competency was developed, comprising 30 questions. SPSS 24.0, R, and Excel 2016 programs were used to analyze the data. Additionally, differences in performances by department and area were analyzed for ICT literacy competency. Item analysis, percent correct, difficulty of percent correct, and item differentiation were also analyzed. Results show that average scores for information creation and information management capabilities for all freshmen by department, excluding natural science and engineering departments, were lower than those for other capabilities. This shows that they are not proficient in employing commonly used ICT tools and adept in general computer management tasks such as file compression and copying. Furthermore, art department students showed statistically significantly lower scores in all competencies than students of other departments. Therefore, different curriculum composition, programming language selection, and teaching and learning strategies are necessary when providing software education to all students. The ICT literacy competency diagnosis tool is essential to evaluate students’ performance levels and determine their actual proficiency in handling ICT.

Aim: This ex-vivo study aimed to compare canal transportation in mesio-buccal canal of mandibular first molars prepared with Mtwo and Revo-S multi-file and Neoniti single-file nickel[18TD$DIF]—titanium (Ni—Ti) rotary systems using cone-beam computed tomography (CBCT). Methodology: CBCTscans were obtained from 60 extracted mandibular first molars and the teeth were randomly divided into three groups. Mesio-buccal canal of mesial root was prepared with Revo-S, Neoniti or Mtwo rotary systems according to the instructions of the manufacturers. Postoperative CBCT scans were also obtained. A single operator performed canal preparations while another operator blinded to the group allocation of teeth did the measurements. Data were analyzed using SPSS 20. The mean and standard deviation (SD) of the amount of canal transportation were calculated and compared between the groups using the Friedman test ([19TD$DIF]P 0.05). Results: No significant difference was noted in canal transportation among the groups in the middle and apical third ([20TD$DIF]P > 0.05). The rotary single-file instrument caused significantly greater canal transportation in the coronal third. Conclusion: No significant difference exists among different rotary systems in the amount of canal transportation caused in the middle and apical third of the mesio-buccal canal in mandibular first molars. Although all rotary files caused some degrees of canal transportation, the rotary single-file instrument caused significantly greater canal transportation than the multiple-file sequences in the coronal third.

Full textAbstract:
This paper is to design a class of manipulators capable of producing five DOF (degree-of-freedom) output motion for controlling the position and orientation of a line. Four novel 5-SPS parallel mechanisms with LMP (Line Moving Platform) are proposed according to the structure coupling-reducing principle proposed by authors on the basis of an existing 5-SPS parallel mechanism with LMP. Three key topology characteristics, such as structure coupling degree, output position and orientation characteristics, input-output kinematic decoupling, and the position workspace characteristics, as the fourth characteristic, of these five 5-SPS parallel mechanisms with LMP are calculated and compared respectively. It shows that the use of concentric spherical joints on the moving platform can reduce coupling degree of mechanisms and simplify the forward displacement and the workspace analysis. The mechanisms with triple-spherical-joint structure have input-output motion decoupling. Therefore, each of the 5-SPS parallel mechanisms with LMP has its own advantages and applications. This paper provides a foundation for engineering design, optimal selection and potential application of the five 5-SPS parallel mechanisms with LMP.

Full textAbstract:
Product reliability is influenced by both design and operating and maintenance practices. This means both the equipment manufacturer and the equipment’s operator have an impact on the systems’ achievable level of availability. Many variables such as application (utility or cogeneration) or service or duty cycle (peaking, cycling, or continuous duty), influence the expected availability/reliability of any unit. These variables and an understanding of the expected “economic demand” the unit must fill are important elements for a realistic and accurate reliability assessment. These variables also affect the expected maintenance costs associated with the unit. Both the equipment manufacturer and the equipment operator have a vested interest in understanding and influencing this process. If the expected level of reliability/availability is a major requirement of the equipment owner/operator, then there must be an accurate understanding of how the reliability of the unit will be protected over the long term. Thus the unit first cost and life cycle cost can be estimated in a meaningful way. The objective of this paper is to provide an assessment of proved design reliability along with the application of on condition maintenance of Turbo Power and Marine Systems’ (Turbo Power) most recent product introduction, the FT8. A computer-aided reliability analysis was made by Turbo Power with the support of Strategic Power Systems, Inc. (SPS), to demonstrate and support the suitability of the FT8 for both peaking and continuous duty applications utilizing on condition maintenance concepts. Consequently, the presentation of the RAM analysis is organized to assist in developing a complete and comprehensive understanding of the evolution of the product and to develop realistic RAM (Reliability, Availability, and Maintainability) and life cycle cost expectations.

The new information technologies and devices have a significant impact on student behavior through the use of social media and communication. Whilst they an inclination to use smart phones and computers to both communicate and surf the internet, students may not capitalize their IT skills and abilities for educational purposes. There is little research in Romania on the student's perceptions towards the use of e-learning in a technical university. The purpose of this paper is to present the results of an exploratory quantitative study that depict student's perceptions towards the use of e-learning and the main advantages and disadvantages for various categories of students from a technical University. Key factors and main advantages and disadvantages used to develop the survey were identified based on a qualitative research. The questionnaire was pretested and administered to 217 students in paper format to multiple Faculties and years of study. Both advantages and disadvantages identified for e-learning were measured on a five-point interval importance scale. SPSS was used for statistical analysis. Factor analysis was performed for both advantages and disadvantages in order to identify the key aspects that characterize student's opinion towards the e-learning The survey compared and contrasted the student's viewpoints from several Faculties and years of study as well as for students from five distinct groups: those that have high grades and receive bursary (merit), those with good grades but just below the bursary threshold (up to one point below), students with poor academic performance and no bursary, those that work (part-time or full time) and those that never worked. Statistical analysis investigated for existence of significant differences due to student's faculty, gender, year of study, age, grades, bachelor or master, and whether or not the student works. This paper provides important results for the University management on both Faculty and University level regarding the key factors influencing student's perceptions towards the use of e-learning.

The purpose of this examination was to explore the effects of stride length (SL) perturbations on walking gait, relative to preferred walking (PW) and running (PR), via lower extremity range of motion (ROM) variability. ROM variability at the hip, knee, and ankle joints, in the sagittal and frontal planes were used in evaluating motor control of gait, where increased gait variability has been previously implicated in fall susceptibly. Nine participants (5 male, 4 female; mean age 23.11±3.55 years, height 1.72±0.18m, mass 72.66±14.37kg) free from previous lower extremity injury were examined. Kinematic data were acquired using a 12-camera system (Vicon MX T40-S; 200Hz). Data filtering and interpolation included a low pass, 4th order, Butterworth filter (15Hz cutoff) and cubic spline. Five gait trials were completed for PW and PR, with subsequent SL manipulations computed as a percentage of leg length (LL). SL perturbations included 60%, 80%, 100%, 120%, and 140% of LL. Kinematic analysis involved one stride (two steps) during each gait trial, assessing ROM at the hip, knee, and ankle from heel contact to toe-off for each limb, in the sagittal and frontal planes. Variability was expressed using coefficient of variation (%). Comparisons were made using 3×7 (joint × stride condition) mixed model ANOVAs, with repeated measures on stride condition (α = 0.05), using SPSS 20.0. Differences in lower extremity ROM variability were detected among stride conditions in the frontal and sagittal planes (F[3.185,76.451] = 3.004, p = .033; F[4.595,110.279] = 2.834, p = .022, respectively). Greater ROM variability was observed at, and in excess of SLs of 100%LL relative to PW in the frontal plane (PW: 9.2±4.2%; 100%LL: 11.8±3.6%, p = .014; 120%LL: 13.5±5.8%, p = .046; 140%LL: 13.8±6.5%, p = .016), and between SLs of 80%LL and 120%LL in the sagittal plane (4.9±3.0%; 7.8±4.7%, p = .046, respectively). From this, PW appeared to occur within SLs of 60%LL to 80%LL, while SLs exceeding 100%LL resulted in increased lower extremity ROM variability. This may have consequences for fall susceptibility at increased stride lengths during walking. PR did not reveal significant variability differences (p>.05) compared to walking conditions in either the sagittal or frontal plane (7.5±5.0%; 12.8±7.7%, respectively), suggesting that running represents a separate, but stable gait pattern. In the sagittal plane, ROM variability was significantly lower at the hip (3.9±1.5%), relative to the ankle (8.4±1.6%, p<.001) and knee joints (7.4±2.6%, p = .001), suggesting that gait control may be more active at the ankle and knee joints. Future investigations should examine kinetic changes in gait when altering stride length.
