Abstract. Mobile spatial data collection is one of the major tasks carried out under the United Nations (UN) to quantify targets of various Sustainable Development Goals (SDGs). Even though there are readily available proprietary solutions to ease mobile spatial data collection, there is often limited educational resources that rely on Free and Open Source Software for Geospatial (FOSS4G). The ongoing efforts of UN OSGeo Committee are to satisfy the requirements of UN operations in terms of identifying and developing open source geospatial software and services. The aim of this paper is to describe and discuss the educational material (tutorial) that is prepared to address the 2019 UN OSGeo Committee Educational Challenge entitled ‘Open geospatial data and software for UN SDG 16, Peace justice and open institution’. The educational material utilised various technologies, including QGIS, QField, PostgreSQL/PostGIS and NodeJS, by relying on a simple mobile spatial data collection scenario, which is collecting information about trees. The scenario serves as an analogy for many different UN operations that might fall under SDG 16, such as interviews with a victim or a vulnerable person or estimating to what extent decision-making is inclusive and responsive. The developed educational material addresses some of the practical requirements of mobile spatial data collection, including handling multiple users, offline data collection, attaching photos to recorded events, editing of spatial features in the field and displaying the collected data on the internet using Heroku. Even though the educational material intends to be self-explanatory, quantitative and qualitative measures are needed to evaluate its efficacy. Therefore, a group of geomatics engineering students were trained with the educational material and their feedbacks were collected through a satisfaction questionnaire as well as the completion time of the tutorial. The outcomes of this paper will be useful in terms of guiding researchers and practitioners who develop online educational material, especially in the geospatial domain.

<p><strong>Abstract.</strong> Communities in Fiji and Tonga rely on landscape services to support a variety of livelihoods. These communities are increasingly vulnerable to climate (e.g. increasing cyclone occurrence and intensity) and environmental (e.g. mining and deforestation) stressors. Within these landscape systems, accurate and timely monitoring of human-climate-environment interactions is important to inform landscape management, land use policies, and climate-smart sustainable development. Data collection and monitoring approaches exist to capture landscape-livelihood information such as surveys, participatory GIS (PGIS), and remote sensing. However, these monitoring approaches are challenged by data collection and management burdens, timely integration of databases and data streams, aligning system requirements with local needs, and socio-technical issues associated with low-resource development contexts. Such monitoring approaches only provide static representation of livelihood-landscape interactions failing to capture the dynamic nature of vulnerabilities, and benefit only a small user base. We present a prototype of a mobile, open-source geospatial tool being collaboratively developed with the Ministries of Agriculture in Fiji and Tonga and local stakeholders, to address the above shortcomings of PGIS and other environmental monitoring and data sharing approaches. The tool is being developed using open-source mobile GIS technologies following a formal ICT for Development (ICT4D) framework. We discuss the results for each component of the ICT4D framework which involves multiple landscape stakeholders across the two Small Island Developing States. Based on the ICT4D user requirements analysis, we produced a prototype open-source mobile geospatial data collection, analysis and sharing tool. New dynamic spatial data layers related to landscape use and climate were specifically developed for use in the tool. We present the functionality of the tool alongside the results of field-testing with stakeholders in Fiji and Tonga.</p>

OpenStreetMap (OSM) represents the most common example of online volunteered mapping applications. Most of these platforms are open source spatial data collected by non-experts volunteers using different data collection methods. OSM project aims to provide a free digital map for all the world. The heterogeneity in data collection methods made OSM project databases accuracy is unreliable and must be dealt with caution for any engineering application. This study aims to assess the horizontal positional accuracy of three spatial data sources are OSM road network database, high-resolution Satellite Image (SI), and high-resolution Aerial Photo (AP) of Baghdad city with respect to an analogue formal road network dataset obtained from the Mayoralty of Baghdad (MB). The methodology of, U.S. National Standard Spatial Data Accuracy (NSSDA) was applied to measure the degree of agreement between each data source and the formal dataset (MB) in terms of horizontal positional accuracy by computing RMSE and NSSDA values. The study concluded that each of the three data sources does not agree with the MB dataset in both study sites AL-Aadhamiyah and AL-Kadhumiyah in terms of positional accuracy.

In this globalization-focused era, the demand for globalized engineers in the creation of borderless societies is increasing. Despite the initiatives by the Japanese government to promote internalization through increasing the intake of foreign students, the exposures gained by the Japanese students from these programs are minimal. For years, internship has been used globally as a platform for training and educating future engineers, but only a few studies have examined the proactive transformation from domestic to international internship. International internships overseas offer a completely new dimension of experiences when carried out in multicultural environments. This article reports and offers evidence of a Japanese engineering university’s rapid global internship reform strategy toward the expansion of international internships in Malaysia. This paper provides insights into the process, from initial setup to implementation of the internship program covering all the necessary preparation and support. From the establishment of an overseas collaboration base and rapport building with hosting industries, the systematic steps taken are reported. Regarding the internship program, feedback from Japanese engineering students who completed their internships show improved satisfaction due to continuous improvement of the internship program with progressing years. It was also discovered that the low participation rate in overseas internship by Japanese students is not due to their inward-looking temperament, but due to the lack of internship program availability that is administered with sufficient preparation enabling them to challenge themselves in a new environment. The challenges encountered in the program, and the sustainable improvements made in alignment with sustainable development goals toward equitable quality education and promotion of lifelong learning are also stated. In this paper, the future perspectives and outlook of internships are also described considering today’s rapid technological advancements and the fast-changing needs of industries, which require future internship programs to have flexible approaches and ideologies.

This article describes an attempt to create open source LabVIEW software, equivalent to data collection and control software. The proposed solution uses GNU Radio, OpenCV, Scilab, Xcos, and Comedi in Linux. GNU Radio provides a user-friendly graphical interface. Also, GNU Radio is a software-defined radio that conducts experiments in practice using software rather than the usual hardware implementation. Blocks for data propagation, code deletion with and without code tracking are created using the zero correlation zone code (ZCZ, a combination of ternary codes equal to 1, 0, and –1, which is specified in the program). Unlike MATLAB Simulink, GNU Radio is open source, i. e. free, and the concepts can be easily accessed by ordinary people without much programming experience using pre-written blocks. Calculations can be performed using OpenCV or Scilab and Xcos. Xcos is an application that is part of the Scilab mathematical modeling system, and it provides developers with the ability to design systems in the field of mechanics, hydraulics and electronics, as well as queuing systems. Xcos is a graphical interactive environment based on block modeling. The application is designed to solve problems of dynamic and situational modeling of systems, processes, devices, as well as testing and analyzing these systems. In this case, the modeled object (a system, device or process) is represented graphically by its functional parametric block diagram, which includes blocks of system elements and connections between them. The device drivers listed in Comedi are used for real-time data access. We also present an improved PyGTK-based graphical user interface for GNU Radio.

Resumen:Se estudia si la percepción de los conocimientos profesionales (disciplinares y pedagógicos) de las educadoras de párvulos de Chile está asociada al nivel de conocimientos que realmente tienen. Con este fin se aplicaron dos instrumentos de recogida de datos, previamente validados. El primero fue un cuestionario diseñado sobre la Encuesta Nacional Docente realizada por el Ministerio de Educación de Chile. El segundo fue la prueba INICIA (Ministerio de Educación de Chile, 2013), aplicada anualmente a los alumnos egresados de las carreras de educación parvularia. Los resultados indican que el nivel de conocimientos técnicos y pedagógicos de las educadoras de párvulos es extremadamente bajo, lo que se ve agravado por una falsa percepción acerca de su nivel de formación disciplinar y pedagógica. Las conclusiones apuntan a que la profesión de educadora de párvulos en Chile tiene un gran desafío formativo por delante. Abstract:It examines whether the perception of professional knowledge (disciplinary and pedagogical) of preschool teachers in Chile is associated with the level of knowledge they actually have. With this aim, two instruments of data collection were applied, previously validated. The first was a questionnaire designed on National Teacher Survey conducted by the Ministry of Education of Chile. The second one was the INICIA (Ministry of Education of Chile, 2013), applied annually to the pupils of nursery education. The results indicate that the level of technical and pedagogical knowledge of pre-school teachers is extremely low, which is exacerbated by a false perception of their level of disciplinary and pedagogical training. The findings suggest that the profession of nursery teachers in Chile has a great educational challenge ahead.
