Abstract

Purpose

This paper introduces a schema for the product assembly feature data in an object-oriented and module-based format using Unified Modeling Language (UML). To link production with product design, it is essential to determine at an early stage which entities of product design and development are involved and used at the automated assembly planning and operations. To this end, it is absolutely reasonable to assign meaningful attributes to the parts’ design entities (assembly features) in a systematic and structured way. As such, this approach empowers processes such as motion planning and sequence planning in assembly design.

Design/methodology/approach

The assembly feature data requirements are studied and definitions are analyzed and redefined. Using object-oriented techniques, the assembly feature data structure and relationships are modeled based on the identified requirements as five UML packages (Part, three-dimensional (3D) models, Mating, Joint and Handling). All geometric and non-geometric design data entities endorsed with assembly design perspective are extracted or assigned from 3D models and realized through the featured entity interface class. The featured entities are then associated (used) with the mating, handling and joints features. The AssemblyFeature interface is realized through mating, handling and joint packages related to the assembly and part classes. Each package contains all relevant classes which further classify the important attributes of the main class.

Findings

This paper sets out to provide an explanatory approach using object-oriented techniques to model the schema of assembly features association and artifacts at the product design level, all of which are essential in several subsequent and parallel steps of the assembly planning process, as well as assembly feature entity assignments in design improvement cycle.

Practical implications

The practical implication based on the identified advantages can be classified in three main features: module-based design, comprehensive classification, integration. These features help the automation and solution development processes based on the proposed models much easier and systematic.

Originality/value

The proposed schema’s comprehensiveness and reliability are verified through comparisons with other works and the advantages are discussed in detail.

Abstract

Purpose

The historic assets are heterogeneous and different to each other, and for this reason, consolidated valuation methodologies do not exist in practice or in the literature. It is, therefore, necessary to dwell on the study of a particular historic building type or category. The assessment process of the valuers of Venetian Villas was explored, focusing on the study of the valuation function construction. The paper investigated if a possible value function, based on the partition of the characteristics, which significantly influence the value, exists and it is generalizable to the whole set of Venetian Villas. The purpose of this paper is to contribute knowledge on the economic valuation of Venetian Villas.

Design/methodology/approach

An application of Hedonic Pricing study to a database of 71 Venetian Villas has been tested. This statistical procedure allowed the authors to discover which results in a percentage of property values can be attributed to the historical characteristics of a building. Using a multiple linear regression and its variables an analysis of residuals and data relating to the variance has been performed.

Findings

This research identifies and proposes, therefore, a valuation approach that can be generalizable to the whole set of Venetian Villas (over 4,000 properties). The models show that the most important variables which influence the value of the villas are: age, internal and external area, maintenance conditions, and author. This model could be used for future valuations of the same type of asset.

Originality/value

The model enables valuers to address better to the property valuation of the Venetian Villas through the valuation functions, which suggest which are the main features which focus in the case of a Venetian Villa valuation and what impact they have on the value asset. The model can be specifically used for valuation reports in the enhancement project of such properties.

Abstract

Purpose

The purpose of this paper is to examine the need to go beyond the “monumentalist” vision in restoration of built heritage and embrace principles of sustainability in this architectural practice.

Design/methodology/approach

Case studies as conceptual reference. Architectural typology.

Findings

The environmental crisis that is currently recognized as one of the most important problems that contemporary society must address urgently is a situation that still has not permeated enough in the practice of monumental restoration, which is still carried out using unlimited resources.

Research limitations/implications

In that sense, the close relationship between the built and the natural environment as an essential ingredient of the vernacular is analysed.

Practical implications

Much of the sustainable principles, that have been put forward as an example to be followed, are elements that have hundreds of years in the constructive tradition.

Social implications

In this context, vernacular architecture has much to contribute in the field of conservation by the enormous accumulated knowledge that its shapes, materials and social use represent.

Originality/value

This experience must be retrieved, but not as an aseptic laboratory experiment, but through its updated application and active implementation to improve the quality of life for inhabitants and contribute to the preservation of our cultural and natural environments.

Abstract

This essay is a historical case study of southern Chilean rural society and its transformation across the twentieth century. It moves beyond questions of unionization and political parties in the agrarian sector to debates about land, subsistence and exploitation to show how notions of “moral economy” in rural politics were formed and transformed in ongoing dialogue with the policies and discourses of the Chilean welfare state. Using judicial records, newspapers, government documents and interviews with almost all the major protagonists, it explores the contradictory effects of both class and ethnic strategies of agrarian restitution, tracing three generations of mobilization in a Mapuche community. Through local evidence, it demonstrates how the Pinochet dictatorship (1973–1990) reorganized and dusted off a state discourse on market-based, efficient agrarian exploitation that had been central to all official explanations and justifications of agrarian reform offered between 1964 and 1973.

Abstract

Purpose

The purpose of this paper is to critically summarize the current data concerning the impact of obesity and micronutrient adequacy and supplementation on the risk and severity of COVID-19 disease, and their potential impact on treatment and rehabilitation.

Design/methodology/approach

PubMed, Scopus and Google Scholar databases were thoroughly searched to identify studies concerning obesity and nutritional status, vitamin and other micronutrients adequacy with COVID-19 severity.

Findings

Individuals with higher body mass index are in greater risk of severe disease and need for mechanical ventilation. Concerning micronutrient adequacy, no published studies at the present time have evaluated the effect of supplementation on the risk and the treatment of the novel disease.

Originality/value

Recently, COVID-19 has monopolized the interest of the medical community regarding diet and nutritional status and it possibly plays an important role in disease severity.
