Suggestion of Safety Certification Standards and Performance Evaluation Methods for Fabricated Mobile Scaffold in South Korea

At construction sites, various types of temporary equipment and structures are used for safety and work efficiency. However, various temporary equipment-related accidents frequently occur for many reasons, including inappropriate installation, usage, and material and structural imperfections. A mobile scaffold is one of the most commonly used indoor temporary equipment for work in high places. In general, the main structural members of the mobile scaffold, such as the mainframes, horizontal members, braces, caster wheels, outriggers, and handrails, are installed on the construction site for this purpose. This means that the load-carrying capacity of the equipment can vary depending on the assembly details. In Korea, there are safety certification standards applied for frequently used temporary equipment, such as scaffolds and shoring. However, the standards concern the strength criteria for the member itself, rather than the global load-carrying capacity. Therefore, it is difficult to review whether the fabricated mobile scaffold has sufficient load-carrying capacity, or to confirm the structural safety considering the various uncertainties affecting the structural performance. In this study, rational safety certification standards and evaluation methods are suggested for fabricated mobile scaffolds. The suggested safety certification standards present structure-level criteria for checking the load-carrying capacity, horizontal stiffness of the structure, and overturning risk. It is expected that the structural performance for safety can be directly checked based on the suggested safety certification standards and performance evaluation methods during the safety certification stage.

The interaction relationships among agricultural certification labels or brands: evidence from Chinese consumer preference for fresh produce

China uses a multilevel agricultural certification system; however, its implications are not well understood. In this study, we used tomatoes as an example in a series of Becker-DeGroot-Marschak auction experiments to determine consumers’ willingness to pay (WTP) toward three safety certification labels and two kinds of brands. Then, based on the auction experiment results, we designed a menu-based choice experiment to assess the interaction relationships between the safety certification labels and brands. The results showed that consumers were generally willing to pay a premium for tomatoes with safety-certified labels (especially for organic labels) and brands (especially for the enterprise brand). Providing consumers with additional information regarding the certification remarkably improved their WTP for tomatoes with organic and green labels. The menu-based choice experiment suggested that the organic and green labels were found to be substitutes. In addition, organic and green labels could not substitute the enterprise brand, whereas the converse of this relationship was true. Finally, a mutual substitution relationship was observed between hazard-free label and enterprise brand. Our research enables producers to consider the interaction between certification strategies and brand strategies. Therefore, marketers and policymakers should take steps to promote and expand consumers’ knowledge on certification, as it could benefit the development of certified food.

Traceability model system as originality assurance method for honey product, Indonesia

Honey is a hype product as immunity booster in the health shock covid-19. Unbalance of supply and demand has raised the price and made the consumer could not afford it. Besides that, global issue about unoriginal honey which spreads in society has made the consumer has negative stigma on SMEs honey product because it does not have complete food safety certification as commercial company. Objective of the research was to increase the consumer trust through originality assurance for honey product from traceability system. The research is a case study with FGD method and then followed by Interpretive Structural Modeling (ISM) analysis and Business Process Notation as solution. Result of the research showed that the distribution aspect has great power to affect the stakeholder and logistic aspects, due to success of both aspects are determined by distribution aspect. While the stakeholder aspect does not have any power to affect other aspect because if the business system has correct SOP, then both aspects will have appropriate supply chain management. Therefore, the solution is business process improvisation, so that to increase the trust local brand for honey product, it must be optimized through recording system of customer journey, so that the producer could trace the barrier and enabler factors about perspective of the honey originality

IEEE P7001: A Proposed Standard on Transparency

This paper describes IEEE P7001, a new draft standard on transparency of autonomous systems1. In the paper, we outline the development and structure of the draft standard. We present the rationale for transparency as a measurable, testable property. We outline five stakeholder groups: users, the general public and bystanders, safety certification agencies, incident/accident investigators and lawyers/expert witnesses, and explain the thinking behind the normative definitions of “levels” of transparency for each stakeholder group in P7001. The paper illustrates the application of P7001 through worked examples of both specification and assessment of fictional autonomous systems.

On the Safety of Mobile Robots Serving in Public Spaces

Since 2014, a specific standard has been dedicated for the safety certification of personal care robots, which operate in close proximity to humans. These robots serve as information providers, object transporters, personal mobility carriers, and security patrollers. In this article, we point out the shortcomings concerning EN ISO 13482:2014, which encompasses guidelines regarding the safety and design of personal care robots. In particular, we argue that the current standard is not suitable for guaranteeing people's safety when these robots operate in public spaces. Specifically, the standard lacks requirements to protect pedestrians and bystanders. The guideline implicitly assumes that private spaces, such as households and offices, present the same hazards as in public spaces. We highlight the existence of at least three properties pertaining to robots’ use in public spaces. These properties include (1) crowds, (2) social norms and proxemics rules, and (3) people's misbehaviours. We discuss how these properties impact robots’ safety. This article aims to raise stakeholders’ awareness on individuals’ safety when robots are deployed in public spaces. This could be achieved by integrating the gaps present in EN ISO 13482:2014 or by creating a new dedicated standard.
