Study on Compressive Properties of Recycling PETs and CANs for Designing a Smart Waste Management Compactor

Recycling is a key process in any sustainable development strategy. This paper proposes solutions for the increasing waste collection rates by developing an educational model for developing innovative waste management solutions. The focus in this paper will be on making the correlation between experimental studies on compressive properties of recycling waste and designing a smart waste management compactor. Based on previous achievements on developing an innovative compactor system with selective waste collection, actual experimental trials will be analysed for generating compression patterns for different types of common waste containers which will be used in the conceptual design process of a compactor, impacting concept definition of all 3 subsystems: mechanical, electrical and software. A dedicated software module for compression parameters will be developed for importing experimental data trials and based on these to process and identify relevant compression parameters defining compression pattern for different common waste containers. These parameters will be used to assist the wok mode state machines for compacting wastes. This will improve compactor performance by optimization of compactor usage smart adaptability.

Towards a conceptual definition of intangible Olympic legacy

PurposeIntangible legacy encapsulates the essence of Olympism and its manifestation, the Olympic Games. Despite significant interest in the capacity of the Olympics to produce notable changes in society, conceptual difficulties in defining and measuring intangible legacy persist. The study develops a conceptual definition of intangible Olympic legacy.Design/methodology/approachThe study follows a four-step concept definition approach. It examines and integrates three strands of literature including intangibles, social interactions and public value, which is combined with insights from a longitudinal empirical investigation of intangible Olympic legacy for National Sport Organisations (NSO).FindingsThe proposed concept of intangible legacy defines it an emerging combination of attributes, interactions, processes and technology, with the goal of creating public value which is the ultimate goal of the Olympic Games. Since intangible legacy is qualitative rather than quantitative, a reconsideration of the current research paradigm is also proposed.Research limitations/implicationsThe study develops a new analytical device for the investigation of intangible legacies for specific publics such as NSO.Practical implicationsThe study carries practical implications for Olympic and events/festival promoters as it allows defining and operationalising the key attributes of the concept.Originality/valueThis is the first study to conceptualise intangible legacy of mega events.

Review of Zero Energy Building Concept-Definition and Developments in Latin America: A Framework Definition for Application in Panama

In recent decades, European countries have developed concepts, definitions, and construction technologies for Zero Energy Building (ZEB) that are effective and correspond to their specific climates. Latin American countries are still trying to find adequate solutions which respond to the local climatic, cultural, social, technical, and economic context. As such, this paper aims to establish the basis of the minimum energy efficiency and the renewable threshold for the definition of ZEB in order to better understand the application in Panama, based on assessing the energy regulations implemented in Panama. To achieve this aim, a review concentrated on the concept-definition and implementation adopted by Latin American countries is presented first before the paper converges into defining a framework for application in Panama. Finally, a case-study-based theoretical framework proposing a ZEB definition for Panama is discussed. The results of this study showed a net primary energy balance, of which the range falls into a plus energy building definition, indicating that all of the cases studied could supply their electricity needs using Photovoltaic generation. All dwellings studied have the potential to become a plus energy building, depending on the available roof surface area. Finally, a strengths, weaknesses, opportunities and threats analysis is presented in order to assess and support the introduction of such a ZEB definition and framework.

THE PROBLEM OF THE BANKRUPTCY CONCEPT DEFINITION IN THE CORPORATE SECTOR

The issue of the bankruptcy notion definition has a major importance in the context of the management practice and theory, internal planning and control of the company. The objectives of the article are to analyse the theoretical principles, highlight and systematize the most successful meanings and definitions related to the term of "bankruptcy", interpreting the economic content of such a category as "bankruptcy in the corporate sector". For this purpose, the method of analysis of the scientific literature was applied. The publications chosen as the research base were mainly selected from the Google Scholar and ResearchGate databases between 2016 and 2020. This study is one of the few researches that involves the analysis of the legal framework especially in the countries of the former Eastern bloc. The results show that the terms that are often used in the bankruptcy literature are: failure, insolvency and bankruptcy. These terms are sometimes used interchangeably, although formally each of them can be defined in a different way. At the same time, following the lexicographical analysis of the concept of bankruptcy in the sustainable development of a company, the authors proposed to visualize the correlation between bankruptcy, financial stability and sustainable development in the corporate sector.

Professional competency: Pre-service mathematics teachers’ understanding toward probability concept

The ability to understand mathematics is a faculty crucial to be possessed by pre-service teachers who will enter into the education sphere. It is one of the professional competencies essential for teachers since satisfactory lessons’ delivery engenders more comprehensible instruction in teachers’ students. Qualitative research employs a descriptive approach relevant to the research purpose, describing mathematics pre-service teachers’ professional competency of understanding the concept toward probability observed based on mathematical abilities; advanced, intermediate, and basic mathematics ability. The subjects are three pre-service teachers having passed discrete mathematics course in a college in Madura. The criteria to select the subjects are the GPA (Grade-point Average) of the last semester and information from the lecturer. It is because unlikely to administer the test due to online learning applied at the college. Findings indicated that the subject with advanced mathematics ability could meet individual concepts, relate concepts and connect concepts with the operations. The subject with intermediate mathematics ability could meet individual concepts, but could not relate to some concepts. However, he could connect concepts with the operations. The subject with basic mathematics ability could not meet individual concepts, relate concepts, and connect concepts with the operations. In terms of the advancement indicator of understanding the concept, the subjects have not attained it since they have not apprehended concept definition well, particularly the probability concept, although the subject with advanced mathematics ability was procedurally prodigious.

Reverse Metadesign: Pedagogy And Learning Tools For Teaching The Fashion Collection Design Process Online

The present article discusses the experience of redesigning the pedagogy and learning tools of a pillar course at the School of Design of XXX, the Metadesign studio course. Metadesign is a design methodology that leads to the concept definition of a new product or service, through a research process that synthesizes design goals, technological and productive constraints, market context and consumption trends for a consumers’ group of reference. It represents a unique methodological approach characterizing the design education as it provides a consolidated research practice able to support the design process. The course structure foresees the reconstruction in phases and successive elaborations of all the elements of context that come into relation with the object of the design process (product, space, service, communication artifact…) influencing its characteristics and creating the “abacus” of elements that make its development possible. In line with the ever-increasing need to reshape the whole education system through the paradigms of digital transformation, and due the acceleration the COVID-19 emergency pushed to the request for on-distance courses, the article presents a renewed reverse course structure, highlighting strengths and opportunities for further improvements that represent a solid base for innovating a fashion design education.
