Abstract

Purpose

Wearables are gaining prominence in the health-care industry and their use is growing. The elderly and other patients can use these wearables to monitor their vitals at home and have them sent to their doctors for feedback. Many studies are being conducted to improve wearable health-care monitoring systems to obtain clinically relevant diagnoses. The accuracy of this system is limited by several challenges, such as motion artifacts (MA), power line interference, false detection and acquiring vitals using dry electrodes. This paper aims to focus on wearable health-care monitoring systems in the literature and provides the effect of MA on the wearable system. Also presents the problems faced while tracking the vitals of users.

Design/methodology/approach

MA is a major concern and certainly needs to be suppressed. An analysis of the causes and effects of MA on wearable monitoring systems is conducted. Also, a study from the literature on motion artifact detection and reduction is carried out and presented here. The benefits of a machine learning algorithm in a wearable monitoring system are also presented. Finally, distinct applications of the wearable monitoring system have been explored.

Findings

According to the study reduction of MA and multiple sensor data fusion increases the accuracy of wearable monitoring systems.

Originality/value

This study also presents the outlines of design modification of dry/non-contact electrodes to minimize the MA. Also, discussed few approaches to design an efficient wearable health-care monitoring system.

Abstract

Purpose

This paper aims to review the shape sensing techniques using large area flexible electronics (LAFE). Shape perception of humanoid robots using tactile data is mainly focused.

Design/methodology/approach

Research papers on different shape sensing methodologies of objects with large area, published in the past 15 years, are reviewed with emphasis on contact-based shape sensors. Fiber optics based shape sensing methodology is discussed for comparison purpose.

Findings

LAFE-based shape sensors of humanoid robots incorporating advanced computational data handling techniques such as neural networks and machine learning (ML) algorithms are observed to give results with best resolution in 3D shape reconstruction.

Research limitations/implications

The literature review is limited to shape sensing application either two- or three-dimensional (3D) LAFE. Optical shape sensing is briefly discussed which is widely used for small area. Optical scanners provide the best 3D shape reconstruction in the noncontact-based shape sensing; here this paper focuses only on contact-based shape sensing.

Practical implications

Contact-based shape sensing using polymer nanocomposites is a very economical solution as compared to optical 3D scanners. Although optical 3D scanners can provide a high resolution and fast scan of the 3D shape of the object, they require line of sight and complex image reconstruction algorithms. Using LAFE larger objects can be scanned with ML and basic electronic circuitory, which reduces the price hugely.

Social implications

LAFE can be used as a wearable sensor to monitor critical biological parameters. They can be used to detect shape of large body parts and aid in designing prosthetic devices. Tactile sensing in humanoid robots is accomplished by electronic skin of the robot which is a prime example of human–machine interface at workplace.

Originality/value

This paper reviews a unique feature of LAFE in shape sensing of large area objects. It provides insights from mechanical, electrical, hardware and software perspective in the sensor design. The most suitable approach for large object shape sensing using LAFE is also suggested.

Purpose

The paper aims to focus on implantable antenna sensors used for biomedical applications. Communication in implantable medical devices (IMDs) is beneficial for continuous monitoring of health. The ability to communicate with exterior equipment is an important aspect of IMD. Thus, the design of an implantable antenna for integration into IMD is important.

Design/methodology/approach

In this review, recent developments in IMDs, three types of antenna sensors, which are recommended by researchers for biomedical implants are considered. In this review, design requirements, different types of their antenna, parameters and characteristics in medical implants communication system (MICS) and industrial, scientific and medical (ISM) bands are summarized here. Also, overall current progress in development of implantable antenna sensor, its challenges and the importance of human body characteristics are described.

Findings

This article give information about the requirements of implantable antenna sensor designs, types of antennas useful to design implantable devices and their characteristics in MICS and ISM bands. Recent advancement in implantable devices has led to an improvement in human health.

Originality/value

The paper provides useful information on implantable antennas design for biomedical application. The designing of such antennas needs to meet requirements such as compact size, patients’ safety, communication ability and biocompatibility.

Abstract

Purpose

This study aims to examine how couplepreneurs foster an entrepreneurial mindset in their kids.

Design/methodology/approach

A qualitative research approach with semi-structured interviews was used as the data collection technique. Narrative analysis was conducted on a sample of 20 couplepreneurs in Mthatha, South Africa.

Findings

Narratives of how couplepreneurs foster an entrepreneurial mindset in their kids included purchasing toys and games for kids that encourage entrepreneurship; competition and team activities among kids that are related to entrepreneurship; the piggy bank; encouraging kids to read entrepreneurial books; and kid entrepreneur showcases.

Research limitations/implications

Sample size challenges are a notable limitation, including research being conducted in only one province of South Africa. Caution is advised when attempting to generalise the results to other contexts.

Practical implications

Understanding the strategies used by couplepreneurs to instil an entrepreneurial mindset in children can help parents to influence and encourage their children's entrepreneurial growth, resulting in more creative and innovative people who make a positive contribution to society, economy and the community.

Originality/value

While there is a body of literature on couple entrepreneurship, there are shortcomings in studies examining how coupleprenuers in African countries instil an entrepreneurial mindset in their children. As a result, this study aims to complement the current corpus of African literature on entrepreneurship, particularly in the context of South Africa.

Abstract

Purpose

The Nigerian construction industry is bedeviled with poor project performance and outcomes which value management (VM) could address if applied. The application of VM on Nigerian construction projects is very minimal due to certain obstacles, namely, lack of VM experts, paucity of knowledge on the techniques, etc., which inhibits the adoption into the construction industry. Therefore, this study aims to develop a conceptual framework of the adoption of VM on construction projects in a typical developing economy.

Design/methodology/approach

This study engaged 15 selected VM experts in two rounds of Delphi survey to develop a conceptual framework of VM adoption. The method of data analysis includes mean score, standard deviation, Kendall’s coefficient of concordance, chi-square (χ2) test, interrater agreement analysis and significant level analysis. The developed conceptual framework was sent to a team of local and international VM experts for validation.

Findings

This study reveals that the adoption of VM requires the collective effort of relevant stakeholders in the construction industry. The framework developed presents individual and collective activities to be undertaken by the stakeholders. The activities include training, legislation, government-funded research, etc. Thus, the adoption of innovative management methodology like VM requires the collaboration of academics, construction professional bodies and government parastatals. This will assist in the judicious use of limited construction resources and boost the relevance of the Nigerian construction industry among developing nations and in the global construction market.

Originality/value

This study used the opinions of few construction professionals that can be regarded as VM experts in Nigeria, as against engaging a pool of construction professionals who may not be knowledgeable in VM process. Engaging the few VM experts in the Nigerian construction industry is important to have a valid basis for drawing conclusion, as large questionnaire survey could be possibly filled by inexperienced or unqualified respondents if stringent criteria are not considered at the outset of this study.

This paper aims to assess the drivers of value management (VM) in the Nigerian construction industry with a view to identify the critical ones through Delphi study.

Abstract

Purpose

This paper aims to assess the drivers of value management (VM) in the Nigerian construction industry with a view to identify the critical ones through Delphi study.

Design/methodology/approach

A team of 15 carefully selected experts in VM were engaged in two rounds of Delphi survey, and the responses of the survey were analyzed with descriptive statistics (mean, standard deviation and mode). Kendall’s coefficient of concordance test and Chi-square (χ2) test were also used to test the level of consensus amongst the respondents at the two rounds of the survey to draw inference. Interrater agreement analysis and significant level analysis were further used to determine the criticality of critical drivers.

Findings

The critical drivers to VM adoption are adequate understanding of the benefits of VM, higher/postgraduate programme that teaches VM technique, professional’s previous experience with VM, collaboration of all construction professional bodies in Nigeria and VM training.

Originality/value

This paper used opinions of VM experts only to achieve the aim of this study as against the common survey method in which respondents who are not knowledgeable in the area of research might fill the questionnaire.
