Abstract The research aims to develop mobile learning media with augmented reality for electrical measurement instruments. The learner can use this application to improve their skills and knowledge about using electrical measurement instruments correctly. One of the essential skills for electricians is using voltmeter, ammeter, and ohmmeter. The result of measuring they can do some analysis about an issue or troubleshooting the electrical field. From the development research, was produced learning media application product was named ARAVO. ARAVO is an abbreviation of augmented reality of Ammeter, Voltmeter, and Ohmmeter. ARAVO helps learners and even lecturers to simulate the use of electrical measuring instruments by combining virtual objects such as multimeter with the real world. Thus will provide a more visible visualization of how to use electrical measuring instruments before they practice directly with actual measuring instruments. ARAVO is a mobile application that can run on the smartphone platform mobile Android. Into the development of this application must go through several stages before it is ready for use.

This study explored gender-related perceptions among male and female pilots and the extent to which such perceptions may cause workplace stress, anxiety, or depression which may affect female pilots. This study utilized two measuring instruments on a sample that consisted of 83 pilots. The two measurement instruments used where the Aviation Gender Attitude Questionnaire (AGAQ) to measure gender bias and the Depression Anxiety Stress Scales-21 (DASS-21) to measure stress, depression, and anxiety among female pilots. There was a significant difference found between men and women across all AGAQ factors. While the results of this study concurred with research that suggests that female pilots are at greater risk for negative perceptions and sexism by male pilots, the results did not indicate any greater degrees of depression, stress, or anxiety in women as compared with their male counterparts.

ABSTRACT Objective: to present and discuss conceptual bases and methods for evaluating the content, construct and criterion validity of self-reported measuring instruments. Method: theoretical study based on the concepts of the Consensus-based Standards for the Selection of Health Measurement Instruments and those evaluated in the Evaluating the Measurement of Patient-Reported Outcomes, which includes concepts of instrument assessment to assess patient-reported outcomes. Results: validity is significant for the methodological quality of an instrument; however, it is a relative criterion, since it depends on the adequacy of the instrument to be measured. There are three different validity measurement properties described in the literature: content, construct and criterion validity. Conclusions: as validity is an important property, it is recommended that it be verified in studies that aimed to develop new scales and in those that adapted and validated for another culture or population.

Measuring instruments are intended to be intelligent, precise, multi-functional and developing multidirectionally, scientific, and reasonable; the reliable evaluation of measurement uncertainty of precision instruments is also becoming more and more difficult, and the evaluation of the Coordinate Measuring Machines (CMM) measurement uncertainty is among the typical problems. Based on Geometric Product Specification (GPS), this paper has systematically studied the CMM uncertainty for evaluating the size and geometrical errors oriented toward measurement tasks, and thus has realized the rapid and reliable evaluation of the CMM uncertainty for task-oriented measurement. For overestimation of the CMM uncertainty for task-oriented measurements in the initial evaluation, a systematic optimization solution has been proposed. Finally, the feasibility and validity of the evaluation model and the optimization method have been verified by three different types of measurement examples of diameter, flatness and perpendicularity. It is typical and representative to systematically solve the problem of the CMM uncertainty for evaluating the measurement tasks targeted at dimensions and geometric errors, and the research contents can be effectively applied to solve the uncertainty evaluation problems of other precision instruments, which are of great practical significance not only for promoting the combination of modern uncertainty theory and practical applications but also for improving the application values of precision measurement instruments.

A systematic review was carried out to examine measurement tools of therapeutic relational communication, using an electronic search of the following databases: PubMed, LILACS, CINAHL, CiberIndex, Scielo and Scopus. The project followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis and the protocol recommended by the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) panel. Thirteen instruments were included in the review. and their measurement properties were tested. The most common communication elements found in the measuring instruments were: empathy, respect, listening, contact, communicative competence, communication quality, and communication skills. Studies that used a theoretical foundation were based on patient-centered humanistic models. Empathy, respect, controlled contact, and other basic elements of interpersonal communication were most commonly found among the measuring regents. In conclusion, this review analyzed the theoretical foundations of the components of instruments used to measure therapeutic relational communication in the nursing field.
