Abstract

Purpose

This paper aims to review existing wireless sensor network (WSN) setups in various domains, focusing on affordable WSN so that it can be effectively utilised in solving the environmental problems. WSN is being explored in many applications such as home security, smart spaces, environmental monitoring, battlefield surveillance and target tracking. WSN consists of a number of tiny, low-powered, energy-constrained sensor nodes with sensing, data processing and wireless communication components. Creating a WSN setup will make the monitoring system effective and in future, it will give a roadmap for solving some common societal problems.

Design/methodology/approach

Various research papers in the area of WSN have been reviewed on the basis of technologies and application on different fields.

Findings

WSN was found to be the most effective solution in areas which are less explored due their hazardous nature and are difficult to reach.

Originality/value

This review is based on research papers available and a recent trend in the area of WSN has been explored.

Abstract

Purpose

Measuring patient satisfaction plays an increasingly important role in the growing push toward healthcare provider accountability. This study seeks to evaluate G.B. Pant Hospital (a North Indian tertiary care centre) patient satisfaction with clinical laboratory services.

Design/methodology/approach

A total of 100 out‐ and in‐patients were randomly selected and interviewed about microbiological services using a standard format, a method which can be easily used to compare patient satisfaction with laboratory services elsewhere.

Findings

Patients represented all age groups: females and males were balanced. Few were from poor socio‐economic backgrounds. Patients do not have problems getting tests done, but the laboratory's inconvenient location caused dissatisfaction. Patients do not have problems communicating with staff, but medical terms are not understood by patients. Hospital cleanliness needs improving, especially toilets, which causes the most patient dissatisfaction. Hospital staff were deemed highly competent and judged to give excellent technical help to patients. The questionnaire's financial subscale shows 100 per cent satisfaction because all tests in the microbiology department are free. The overall satisfaction with services stood at 83 per cent. Satisfaction scores for G.B. Pant Hospital appear to be satisfactory.

Research limitations/implications

This study does not compare patient satisfaction in two or more hospitals and findings may not be generalisable.

Practical implications

Patient satisfaction surveys are the best way to identify deficiencies and improve hospital services. Repeating studies at six monthly intervals is a useful managerial intervention aimed at delivering and maintaining quality healthcare.

Originality/value

This laboratory satisfaction survey is the first of its kind for government hospitals in India. The survey revealed a positive feedback and helped to identify the areas of concern along with estimating the patient satisfaction scores. This is the best way to identify the areas of deficiencies and improving the services provided by the hospital. The authors feel that repeating such studies at a regular interval of six months would be a useful guide for the managerial interventions.

Abstract

Purpose

The purpose of this paper is to investigate the impact of employer branding strategy (a mechanism used by organisations to hire and retain competent talent) on employee engagement whilst simultaneously measuring the mediating effect of person-organisation (P-O) fit.

Design/methodology/approach

The study analyses a sample of 296 employees working in the BPO sector in India. The proposed model is tested with the help of structural equation modelling.

Findings

The findings of the research highlight that employer branding has an affirmative relationship with P-O fit and employee engagement. The findings also reveal that P-O effect has a partial mediating effect on the relationship between employer branding and employee engagement.

Practical implications

Understanding and implementing employer branding strategies provides the organisation with a tool for not only harnessing good employees but also facilitates them to engage and retain them. Employer branding strategies ensure an increase in employee’s sense of belongingness and alignment of goals. Value congruence in the form of person organisation fit also ensures that employees believe that they are valued across the organisation and may go an “extra mile” to achieve organisational objectives.

Originality/value

Employer branding is a comprehensive strategy which can be used by employers to attract and retain talented employees. In a global economy where a talented workforce is scarce and has plenty of choices available to them, firms can use employer branding as a strategic opportunity to enhance employee engagement.

Abstract

Purpose

Oral health is an integral part of the general health, however, oral health has been given lower priority than other health problems especially among the underprivileged refugee population. Out of total refugees in the world, 70 percent of the refugees belong to Tibet. The purpose of this paper is to assess the dental caries status and treatment needs of Tibetans residing in Shimla, Himachal Pradesh, India and to explore and suggest better oral health care delivery to them.

Design/methodology/approach

Tibetans above the age of 12 years were included in this cross-sectional study. American Dental Association Type-3 examination was conducted. Data regarding demography and oral health practices was recorded on a structured format. For recording dental caries, dentition status and treatment need index was used. The data were analyzed using the SPSS statistical software. χ2 test, student t-test, and ANOVA test were used.

Findings

A total of 18,831 teeth were examined among which 82 percent were sound, 16.7 percent decayed, 0.7 percent were filled without decay, 0.1 percent filled with decay, 0.03 percent were bridge abutments and 0.15 percent teeth had traumatic injury. The mean DMFT was 7.3 and it was increasing with the age. Mean number of teeth requiring one surface filling, two or more surface filling, pulp therapy, and extraction was 1.27, 0.39, 0.21, and 2.08, respectively.

Originality/value

The study revealed low prevalence of dental caries among Tibetans and dental treatment requirement steadily increased with the advancement of age and was also related to other factors like poverty, education, and their tough life where oral health is given no priority.

Abstract

Breast cancer (BC) is one of the leading cancer in the world, BC risk has been there for women of the middle age also, it is the malignant tumor. However, identifying BC in the early stage will save most of the women’s life. As there is an advancement in the technology research used Machine Learning (ML) algorithm Random Forest for ranking the feature, Support Vector Machine (SVM), and Naïve Bayes (NB) supervised classifiers for selection of best optimized features and prediction of BC accuracy. The estimation of prediction accuracy has been done by using the dataset Wisconsin Breast Cancer Data from University of California Irvine (UCI) ML repository. To perform all these operation, Anaconda one of the open source distribution of Python has been used. The proposed work resulted in extemporize improvement in the NB and SVM classifier accuracy. The performance evaluation of the proposed model is estimated by using classification accuracy, confusion matrix, mean, standard deviation, variance, and root mean-squared error.

The experimental results shows that 70-30 data split will result in best accuracy. SVM acts as a feature optimizer of 12 best features with the result of 97.66% accuracy and improvement of 1.17% after feature reduction. NB results with feature optimizer 17 of best features with the result of 96.49% accuracy and improvement of 1.17% after feature reduction.

The study shows that proposal model works very effectively as compare to the existing models with respect to accuracy measures.

Abstract

Purpose

This paper aims at providing a comparative analysis of the existing protocols that address the security issues in the Future Internet (FI) and also to introduce a Collaborative Mutual Identity Establishment (CMIE) scheme which adopts the elliptical curve cryptography (ECC), to address the issues, such as content integrity, mutual authentication, forward secrecy, auditability and resistance to attacks such as denial-of-service (DoS) and replay attack.

Design/methodology/approach

This paper provides a comparative analysis of the existing protocols that address the security issues in the FI and also provides a CMIE scheme, by adopting the ECC and digital signature verification mechanism, to address the issues, such as content integrity, mutual authentication, forward secrecy, auditability and resistance to attacks such as DoS and replay attack. The proposed scheme enables the establishment of secured interactions between devices and entities of the FI. Further, the algorithm is evaluated against Automated Validation of Internet Security Protocols and Application (AVISPA) tool to verify the security solutions that the CMIE scheme has claimed to address to have been effectively achieved in reality.

Findings

The algorithm is evaluated against AVISPA tool to verify the security solutions that the CMIE scheme has claimed to address and proved to have been effectively achieved in reality. The proposed scheme enables the establishment of secured interactions between devices and entities of the FI.

Research limitations/implications

Considering the Internet of Things (IoT) scenario, another important aspect that is the device-to-location (D2L) aspect has not been considered in this protocol. Major focus of the protocol is centered around the device-to-device (D2D) and device-to-server (D2S) scenarios. Also, IoT basically works upon a confluence of hundreds for protocols that support the achievement of various factors in the IoT, for example Data Distribution Service, Message Queue Telemetry Transport, Extensible Messaging and Presence Protocol, Constrained Application Protocol (CoAP) and so on. Interoperability of the proposed CMIE algorithm with the existing protocols has to be considered to establish a complete model that fits the FI. Further, each request for mutual authentication requires a querying of the database and a computation at each of the participating entities side for verification which could take considerable amount of time. However, for applications that require firm authentication for maintaining and ensuring secure interactions between entities prior to access control and initiation of actual transfer of sensitive information, the negligible difference in computation time can be ignored for the greater benefit that comes with stronger security. Other factors such as quality of service (QoS) (i.e. flexibility of data delivery, resource usage and timing), key management and distribution also need to be considered. However, the user still has the responsibility to choose the required protocol that suits one’s application and serves the purpose.

Originality/value

The originality of the work lies in adopting the ECC and digital signature verification mechanism to develop a new scheme that ensures mutual authentication between participating entities in the FI based upon certain user information such as identities. ECC provides efficiency in terms of key size generated and security against main-in-middle attack. The proposed scheme provides secured interactions between devices/entities in the FI.
