Published: July 2021

There are seemingly opposing findings on social media’s effect on mental well-being. Some studies report no detrimental effects, others no association and others even positive or buffering effects. However, social media has rapidly evolved in a short span of time and so has people’s use of the platforms. Collecting an accurate measure of social media use and other methodological challenges particularly affect data in this area. In this commentary, we discuss two longitudinal studies to elaborate these contracting findings on social media and mental health.
Attitudes of primary school teachers in Croatia toward Music as a school subject / Stališča osnovnošolskih učiteljev na Hrvaškem do glasbe kot šolskega predmeta
Authors: Dobrota Snježana , Vrančić Antonija , Križanac Ivana
Published: July 2021

The paper explores the influence of years of work experience, professional qualifications, additional music education, engaging in music activities in leisure time, and going to the theatre/classical music concerts on the attitudes of primary school teachers toward the school subject Music. The research was conducted on a sample of primary education teachers from all Croatian counties (N = 233), using a questionnaire composed of two parts: The General Data Questionnaire and Attitudes Toward Music as a School Subject. The results confirm that primary school teachers with fewer years of work experience have more positive attitudes toward the Curriculum of Music Education for Primary Schools and for Grammar Schools in the Republic of Croatia, while in other aspects of attitudes no difference was found. Furthermore, no differences were found in the attitudes of primary school teachers toward the subject Music with regard to their professional qualifications. Primary education teachers who have attended additional music classes, who engage in music activities in leisure time and who often attend theatre/classical music concerts, consider Music to be an important school subject that relaxes the students, and consider themselves more competent to teach music. The obtained results have significant implications in terms of music pedagogy, with regard to organizing the music education of preservice primary teachers and their lifelong learning.
Glasbeniki in blagostanje: pregled literature / Musicians and psychological well-being: Systematic review
Authors: Pogačnik Aleš
Published: July 2021

The purpose of this article is to review the studies that are related to the research of well-being in professional musicians and students of music who are on their way to starting their professional careers in music. Currently, there aren‘t many such studies available, but their number is growing rapidly. Psychological well-being is a topic that has become popular with professional musicians in the last ten years, while interest in this field of research has been growing. Based on the analysed scientific and research sources, we can conclude that the latter sources are based on different theoretical assumptions about well-being, as a uniform and generally accepted definition of well-being hasn‘t been adopted yet. So far, all studies have focused on a wide range of participants with diverse characteristics, in which identifying factors have been found that have an influence on whether the levels of one‘s well-being are low or high, as well as provide a base for planning an introduction to applying appropriate forms of intervention to raise one‘s level of well-being. One of the key aspects of moderating well-being is the relational aspect. Studies performed so far have made it clear that, in the future, we may expect an increase in the development of interest, as well as conducted research, in the field of well-being in musicians; moreover, we may expect the development of more clearly defined forms of intervention that would lead to increased levels of well-being in musicians, starting at the level of musical education and moving forward.

Authors: Owen Emily , Farris Zachary , Razoliarivelo Haingoniaina Lalatiana , Griffin Jamie , Farris Alisha
Published: July 2021

Background: Due to lack of resources, especially for mothers and children, Madagascar has high levels of malnutrition. Health promotion and education have shown to be effective in increasing health status in limited-resource areas. This study piloted a tailored, four-week health and nutrition counseling program to improve diet diversity and health promoting practices.

Methods: Twenty child caregivers were recruited from Andasibe, Madagascar, using snowball sampling, and were provided weekly individualized health counseling with education materials by the research team. Diet, health knowledge, and health behaviors were assessed using a quasi-experimental one-group pre/post-test design. Body mass index, mid-upper arm circumference measurements, and Raman spectroscopy technology assessed nutritional status. Data were analyzed using descriptive statistics and paired sample t-tests to determine changes.

Results: All caregivers were female. More caregivers were within normal limits for Body Mass Index (40%) than underweight or overweight, and most were within normal limits for mid-upper-arm circumference (75%). Significant increases (p≤0.01) were found in caregiver consumption of vitamin A-rich foods, and using treated water to wash fruits and vegetables, though significant increases were not found for children. The majority (80%) increased diet diversity. Participants increased their knowledge of nutrition and non-nutritious foods.

Conclusions: Results suggest an individualized approach to health promotion in a limited-resource area can improve diet diversity, knowledge and health practices. Opportunities for further education and research include increasing knowledge of nutrient dense foods, expanding food choice beyond carbohydrate-rich foods, diet diversity importance, and sustaining education efforts beyond project implementation. Strategies highlighted in this research can inform others working in limited-resource areas.

Authors: Ncube-Murakwani Pamela
Published: July 2021

The Amalima program in Matabeleland North and Matabeleland South Provinces of Zimbabwe, an intervention funded by the United States Agency for International Development (USAID) Office of Food for Peace, promoted Care Groups from 2014-2020. Care Groups are community peer- to- peer support groups that provide a platform for promoting optimal nutrition and health for pregnant and lactating women, as well as children 6-23 months of age through training sessions run by community group leaders to promote recommended maternal, infant and young child nutrition practices. A qualitative study was conducted to describe adolescent mother inclusion and participation in Care Groups, highlighting key enablers and barriers for participation.  A total of 28 in-depth interviews were conducted with adolescents in Care Groups, as well as adolescents not participating in Care Groups. Focus group discussions were also held with family members of adolescents. The key enablers for Care Group participation by adolescent mothers were found to include the motivation to learn how to take care of their children, the social and interactive benefits, family support, and positive facilitator attitudes. Key barriers to participation were workload and chores at home, lack of family support, and lack of adolescent-friendly approaches amongst facilitators. Key recommendations include training facilitators on adolescent-friendly approaches and group dynamics so they can better understand and relate to adolescents.

Authors: Kovalev R. B. , Kornienko V. V. , Ratushnak V. N.
Published: July 2021

A significant number of patents and publications in the open press show the intensity of the ongoing research to create new methods of synchronization and specialized ground-based equipment for frequency-time synchronization. The article considers the implementation of an autonomous synchronization system between ground-based satellite communication points, which is used in conditions of unfavorable reception or absence of signals from global navigation satellite systems. The paper presents studies on the assessment of the error of time synchronization of geographically separated ground points of satellite communications. The basics of constructing the receiving equipment of a radio engineering system are considered and the mutual correlation of the reference signal of the receiving equipment and the received input synchronization signal is calculated. The results of field tests of mutual synchronization equipment are presented, where the potential synchronization accuracy of equipment at ground objects with previously unknown coordinates was determined, while the synchronization equipment provided measurement of the signal propagation time from one ground object to another with the formation of universal time scales on points. The method of mutual synchronization of linked points is carried out by the duplex method at a frequency of 1065 MHz (request) and 625 MHz (response) by phase-code-manipulated signals with a base equal to 1023 and a duration of 0,1 ms.

Published: July 2021

The research purpose to describe and analyze the mathematical problem solving abilities of MTs students in solving Geometry Transformation problems through Online Learning due to the Covid-19 pandemic int Indonesia. The research method used is descriptive qualitative. The subjects of this research were 3 students of MTs Al-Hamid Class IX who were selected as representatives of the very good problem-solving ability category, the problem-solving ability level category was sufficient, and the problem-solving ability level category was lacking. The data collection technique used was a test consisting of 4 non-routine items and interviews. The results of the analysis can be obtained: (1) students with excellent problem-solving abilities are able to fulfill the 4 steps of solving according to their pattern but there are errors in understanding the problem in question 1. (2) students with sufficient problem-solving skills are only able to solve problems in question 1 and 2 while 3 and 4 there are errors in understanding the questions. (3) students with poor problem solving skills were only able to solve problems in question 2, while in questions 3,4 and 5 there were errors in understanding the questions. The student error factor is due to the lack of understanding of the concept of geometric transformation to do the test because the geometric transformation test questions given are non-routine, while the geometric transformations that are often encountered only substitute formulas without understanding the concept of geometric transformation which includes translation, reflection, rotation and dilation. Many have to do with everyday life so that students experience difficulties in what is meant in the questions, especially in questions 3 and 4.

Aluminum and composite materials are the types of materials that are used to construct structures on aircraft airframes. It is not uncommon for both types of materials to be used together with the joining method. In the process of connecting between two types of material in the aircraft structure, it is mostly carried out by the riveting method. This process is carried out by making a hole in the two materials according to the rivet diameter and then the hole diameter is then filled with rivets and the riveting process is carried out. The process uses rivets so that it will relatively increase the weight of the structure because there is additional rivet material. In this study, the objectives are to determine the mechanical strength of the joint between the composite and aluminum sheet metal using the mechanical clinching and riveting processes. The method used is an experimental method, namely by making test specimens with composite and aluminum, solid rivet type fasteners and punches to determine the connection of the riveting, the drilling process is carried out with a hole diameter of 3.5 mm, for the clinching method with variations in the diameter of the punch 3.5 mm, 4.0 mm. , and 4.5 mm. Then the tensile test, macro photo test were carried out. The results obtained from this research are that the maximum load increase in the specimen tested by clinching is because the damage length (gap) value is obtained at the joint boundary between the rivet and the test material.

Electronic administration system is one of the best solutions in the current digital era, electronic-based systems are considered to make it easier for an organization to process data and can reduce the possibility of data loss due to human error or natural disasters. The current administrative data management application is called the Electronic Office (E-Office). The E-Office handles data for  incoming mail, outgoing mail and mail disposition. There are frequent delays in receiving information and validating letter files that are still carried out using physical files, so the mobile e-office is a solution that can be used by an agency to make it easier  for workers to access information more quickly and can be done anywhere. Data security is an important thing that needs to be considered in an electronic transaction, so this research will add data security to the mobile e-office using sha-256 and lamport schemes. We present data on the results of this mobile e-office test on mobile devices and virtual private servers (vps), the data is in the form of functional application performance testing results and records of processing time performed by mobile and vps devices. From this  data an analysis will be carried out to determine the appropriateness of the devices that can be used in running a mobile e-office.

The aim of this research is to explain the significance of digital literacy-based learning in the study of SKI at Madrasah Ibtidaiyah. In fact, few teachers have introduced digital literacy-based learning in the classroom. This is due to teachers' lack of understanding of how to use digital technology. This thesis employs qualitative descriptive analysis techniques in conjunction with field research. Techniques for gathering data included observation, interviews, and documentation. Descriptive analysis methods were used to analyze the data. Furthermore, comparing, checking the data's validity, and decrypting the data are all tasks that must be completed. The study's findings show that SKI's digital literacy-based learning is divided into four stages: (1) learning preparation, which includes deciding digital content based on the syllabus and lesson plans that will be provided to students; (2) digital material selection, which includes choosing digital files that will be shown during learning, such as images, movies, animated videos, or songs by examining whether or not the digital file is authorized. The learning material presented becomes more relevant and students become more engaged in learning as a result of digital literacy. This study serves as a resource for teachers interested in implementing digital literacy-based SKI learning, especially at Madrasah Ibtidaiyah

This study was conducted to find out the interpretations of Islamic criminal law verses and to see the polemics which occurred in the applications of Islamic criminal law in Indonesia alongside the harmonization of its applications in Indonesia. This study used a normative-descriptive approach in a way that explained in detail the laws and the verses’ interpretations as well as the polemics of Islamic criminal law in the Indonesia’s positive law. In the context of the development and application of national law in Indonesia, Islamic law is one of the sources adopted. Islamic law itself regulates the vertical relationship with Allah and the relationship with humans. These two relationships have a role in the formation of national law in Indonesia. In terms of applications, Islamic law can contribute to the development of positive law with the following three alternatives: 1) Islamic law which is a continuation of legal politics in the colonial period, either through transitional rules of the 1945 Constitution’s article 2 or by means of being stipulated in the further new legislation, 2) positive Islamic law which is sourced from Islamic values, and 3) the theory of legal leveling.  This theory is applied to make Islamic law a source of national law in the future.
