Less than ten years ago, working in archives and IT sector did not have much in common. The researchers had to come to the reading room in order to study the inventories and documents, and then to make notes by transcribing or photocopying the document itself. Today, the rapid development of technology has enabled everything to be done with just a few clicks; the inventory is reviewed online on the archives’ website, a request for specific documents is sent, and the requested scans arrive at the researchers’ e-mail address. In order to achieve this, it was necessary to digitize a wide variety of archival formats beforehand. The aricle discusses the post-processing methods used by the Archives of Bosnia and Herzegovina and presents all the advantages and disadvantages that have been demonstrated in practice so far.

New technologies primarily affect the lives of all people, their habits, needs, desires, but also significantly affect the demands placed on various business sectors. Discussions on the increasingly rapid development of technical-technological solutions that can be applied in the postal sector and logistics have a long history. New technologies in all areas bring a constant change in the relationship between companies and their customers, which significantly affect the quality of work and activities. In the years to come, it will be an increasing challenge for postal operators around the world, as well as for other companies, to achieve substantive communication and understanding of their customers through the application of innovative technologies. Understanding and learning about customer issues is key to offering them services that, with their precise targeting of stakeholders, quality, visibility, efficiency, and, perhaps most importantly, flexibility, will be able to meet needs that change so quickly over time. This will be possible with new technologies and innovative solutions. The paper presents a market research on the potential use of autonomous vehicles and drones in the postal sector in Bosnia and Herzegovina. The research is based on a survey questionnaire on the use of drones and autonomous vehicles in the postal sector in the segment of shipment delivery.

Additive manufacturing, commonly known as 3D printing, is an advancement over traditional formative manufacturing methods. It can increase efficiency in manufacturing operations highlighting advantages such as rapid prototyping, reduction of waste, reduction of manufacturing time and cost, and increased flexibility in a production setting. The additive manufacturing (AM) process consists of five steps: (1) preparation of 3D models for printing (designing the part/object), (2) conversion to STL file, (3) slicing and setting of 3D printing parameters, (4) actual printing, and (5) finishing/post-processing methods. Very often, the 3D printed part is sufficient by itself without further post-printing processing. However, many applications still require some forms of post-processing, especially those for industrial applications. This review focuses on the importance of different finishing/post-processing methods for 3D-printed polymers. Different 3D printing technologies and materials are considered in presenting the authors’ perspective. The advantages and disadvantages of using these methods are also discussed together with the cost and time in doing the post-processing activities. Lastly, this review also includes discussions on the enhancement of properties such as electrical, mechanical, and chemical, and other characteristics such as geometrical precision, durability, surface properties, and aesthetic value with post-printing processing. Future perspectives is also provided towards the end of this review.

Type Ii Errors

Digital transformation has led to changes in business models of traditional players in the existing markets. What is more, new entrants and new markets appeared, in particular platforms and multisided markets. The emergence and rapid development of platforms are caused primarily by the existence of so called indirect network externalities. Regarding to this, a question arises of whether the existing instruments of competition law enforcement and market analysis are still relevant when analyzing markets with digital platforms? This paper aims at discussing advantages and disadvantages of using various tools to define markets with platforms. In particular, we define the features of the SSNIP test when being applyed to markets with platforms. Furthermore, we analyze adjustment in tests for platform market definition in terms of possible type I and type II errors. All in all, it turns out that to reduce the likelihood of type I and type II errors while applying market definition technique to markets with platforms one should consider the type of platform analyzed: transaction platforms without pass-through and non-transaction matching platforms should be tackled as players in a multisided market, whereas non-transaction platforms should be analyzed as players in several interrelated markets. However, if the platform is allowed to adjust prices, there emerges additional challenge that the regulator and companies may manipulate the results of SSNIP test by applying different models of competition.

BACKGROUND Background: Online forward triage tools (OFTT) or symptom checkers are being widely used during this COVID-19 pandemic. The effects and utility of such tools however, have not been widely assessed. OBJECTIVE Objective: To assess the effects (quantitatively) and the utility (qualitatively) of a COVID-19 OFTT in a pandemic context, exploring patient perspectives as well as eliciting recommendations for tool improvement. METHODS Methods: We employed a mixed-method sequential explanatory study design. Quantitative data of all users of the OFTT between March 2nd, 2020 and May 12th, 2020 were collected. A follow-up survey of people who consented to participation was conducted. Secondly, qualitative data was collected through key informant interviews (n=19) to explain the quantitative findings, as well as explore tool utility, user experience and elicit recommendations. RESULTS Results: An estimate of the effects, (quantitatively) and the utility (qualitatively) of a COVID-19 OFTT in a pandemic context, and recommendations for tool improvement. In the study period, 6,272 users consulted our OFTT; 560 participants consented to a follow-up survey and provided a valid e-mail address. 176 (31.4%) participants returned a complete follow-up questionnaire. 85.2% followed the recommendations given. 41.5% reported that their fear was allayed after using tool and 41.1% would have contacted the GP or visited a hospital had the tool not existed. Qualitatively, seven overarching themes emerged namely i) accessibility of tool, ii) user-friendliness of tool, iii) utility of tool as an information source, iv) utility of tool in allaying fear and anxiety, v) utility of tool in decision making (test or not to test), vi) utility of tool in reducing the potential for onward transmissions (preventing cross infection) and vii) utility of tool in reducing health system burden. CONCLUSIONS Conclusion: Our findings demonstrated that a COVID-19 OFTT does not only reduce the health system burden, but can also serve as an information source, reduce anxiety and fear, reduce cross infections and facilitate decision making (to test or not to test). Further studies are needed to assess the transferability of these COVID-19 OFTT findings to other contexts as the second wave sweeps across Europe.

Additive manufacturing of stainless steel is becoming increasingly accessible, allowing for the customisation of structure and surface characteristics; there is little guidance for the post-processing of these metals. We carried out this study to ascertain the effects of various combinations of post-processing methods on the surface of an additively manufactured stainless steel 316L lattice. We also characterized the nature of residual surface particles found after these processes via energy-dispersive X-ray spectroscopy. Finally, we measured the surface roughness of the post-processing lattices via digital microscopy. The native lattices had a predictably high surface roughness from partially molten particles. Sandblasting effectively removed this but damaged the surface, introducing a peel-off layer, as well as leaving surface residue from the glass beads used. The addition of either abrasive polishing or electropolishing removed the peel-off layer but introduced other surface deficiencies making it more susceptible to corrosion. Finally, when electropolishing was performed after the above processes, there was a significant reduction in residual surface particles. The constitution of the particulate debris as well as the lattice surface roughness following each post-processing method varied, with potential implications for clinical use. The work provides a good base for future development of post-processing methods for additively manufactured stainless steel.
