Big Man with a 3D-Printed Gun: One Possible Solution to the Public Safety Problems Presented by Manufacturing Non-Metal Firearms with 3D Printers

The circular economy model offers great opportunities to companies, as it not only allows them to capture additional value from their products and materials, but also reduce the fluctuations of price-related risks and material supply. These risks are present in all kind of businesses not based on the circular economy. The circular economy also enables economic growth without the need for more resources. This is because each unit has a higher value as a result of recycling and reuse of products and materials after use. Following this circular economics framework, the Polytechnic University of Madrid (Universidad Politécnica de Madrid, UPM) has adopted strategies aimed at improving the circularity of products. In particular, this article provides the result of obtaining recycled PLA filament from waste originating from university 3D FFF (fused filament fabrication) printers and waste generated by “Coronamakers” in the production of visors and parts for PPEs (Personal Protective Equipment) during the lockdown period of COVID-19 in Spain. This filament is used in the production of 3D printed parts that university students use in their classes, so the circular loop is closed. The obtained score of Material Circularity Indicator (MCI) of this material has been calculated, indicating its high level of circularity.

While assistive technology is often suggested as a way to increase, maintain, or improve functional ability for individuals with disabilities within physical activity (PA) settings, cost and availability of such items are often noted as barriers. In recent years, 3D printing has become available to the general public through the adoption of 3D printers in schools, libraries, and universities. Through individual design and rapid prototyping, 3D printing can support physical educators in accommodating student need for assistive technology through a multitude of modification possibilities. This article will highlight the capacity for 3D printed assistive technology within educational settings, and will illustrate how teachers, APE specialists, and other related service personnel can utilize this technology to support student success in PE and PA settings. This article will also assist practitioners with locating, uploading, and utilizing existing collections of 3D assistive technology models from open-source websites, such as Thingiverse.

Plastic Parts

3D printing is a process that has become widely used in recent years, allowing the production of parts with relatively complicated shapes from metallic and non-metallic materials. In some cases, it is challenging to evaluate the ability of 3D printers to make fine details of parts. For such an assessment, the printing of samples showing intersections of surfaces with low angle values was considered. An experimental plan was designed and materialized to highlight the influence of different factors, such as the thickness of the deposited material layer, the printing speed, the cooling and filling conditions of the 3D-printed part, and the thickness of the sample. Samples using areas in the form of isosceles triangles with constant height or bases with the same length, respectively, were used. The mathematical processing of the experimental results allowed the determination of empirical mathematical models of the power-function type. It allowed the detection of both the direction of actions and the intensity of the influence exerted by the input factors. It is concluded that the strongest influence on the printer’s ability to produce fine detail, from the point of view addressed in the paper, is exerted by the vertex angle, whose reduction leads to a decrease in printing accuracy.

The One

The outbreak of COVID-19 has placed a heavy burden on society, threatening the future of the entire world as the pandemic has hit health systems and economic sectors hard. Where time moves fast, continuing curfews and lockdown is impossible. This paper assembles three main safety behaviors, social distancing, wearing a facemask, and hygiene in one model (PSC Triangle) to be practiced by the public. Integrating public safety compliance with these behaviors is the main recommendation to slow the spread of COVID-19. Although some concerns and challenges face these practices, the shifting of public behaviors to be more safety-centered is appropriate and available as an urgent desire exists to return to normal life on the one hand and the medical effort to find effective cure or vaccine that has not yet succeeded on the other hand. Recommendations to enhance public safety compliance are provided.

Os mecanismos de gestão da segurança pública são instrumentos administrativos que potencializam os resultados de políticas nessa área. É o caso dos Conselhos, Planos, Fundos e Secretarias Municipais de Segurança Pública, além das Guardas Municipais. O artigo tem como objetivo verificar se a adoção de tais mecanismos produz impacto nos indicadores de violência. Paratanto, foram construídos o Índice de Gestão Municipal da Segurança Pública e o Índice de Violência. A partir de análise de correlaçãoentre tais variáveis, aponta que o nível atual de adoção dos mecanismos de gestão avaliados é muito baixo em todas as unidades federativas do Brasil, e não consegue influenciar os níveis de violência. Conclui que, ao omitir-se de implementar mecanismos degestão da segurança pública, o poder municipal, como ente mais próximo da população, enfraquece uma estrutura administrativa quedeveria servir de base para as políticas públicas voltadas para a redução da violência no âmbito local.Palavras-chave: Poder municipal, gestão, políticas públicas, violência.MUNICIPAL MANAGEMENT OF THE PUBLIC SAFETY: responsibility of the Brazilian municipalities for combating violenceAbstract: Mechanisms of the public security management are administrative tools that have improved the policies results in this area. This is the case of the Councils, Plans, Funds and Public Safety Secretariats, besides Municipal Guards. The paper aims to verify whether the adoption of such mechanisms has impacts on the violence indicators. Therefore, were built the Municipal Public Security Management Index and Violence Index. From the analysis of correlation between these variables was observed that the present level of adoption of management mechanisms is very low in all federative units of Brazil, and does not influence the levels of violence. Concludes that to omit to implement mechanisms of public safety management, the municipal power, as nearest entity of the population, weakens the administrative structure which should be the basis of all local public security policies.Key words: Municipal government, management, public policies, violence.

On June 2nd, 2020, the Canadian Association for Security and Intelligence Studies (CASIS) Vancouver hosted its second digital roundtable event of the year titled, “Privacy and Security: Working Hand in Hand to Protect You Online.” This presentation featured Dr. Patrick Neal who has been involved in the public safety field since 1982. Dr. Neal’s presentation focused on the cohesiveness of privacy and security in the near future, privacy constructs, myths and harms of privacy, and privacy enhancing technologies. The subsequent roundtable discussion centered around Dr. Neal’s lecture in a question and answer period. APA Citation CASIS Vancouver. (2020).
