Abstract
The effect of different kind of pigments on the corrosion resistance properties of an epoxy paint has been investigated using electrochemical impedance spectroscopy and open circuit potential measurements. Painted naval steel samples were studied during the exposure to artificial sea water. The epoxy paint coatings were prepared employing red lead, zinc, red iron oxide or titanium dioxide as pigment with 0.8 of PVC/CPVC ratio. From the EIS and corrosion potential data analyis was found that the anticorrosive protection given by an anticorrosive (pigmented with red lead) and a top coat (pigmented with red iron oxide) epoxy painting scheme was both more lasting and more effective. This was attributed to the fact that both the effective adhesion provided by the chemical bonding between the steel surface and the epoxy paint groups and the constant high barrier effect afforded by this type of top coat were a perfect complement for the high corrosion inhibitive capacity of the red lead pigment.

Abstract
Purpose
Facilities management plays a significant role in the housing industry to support human daily routine and enhancing the productivity of the activities in and around the residential. Nonetheless, facilities management has not been readily encouraged or adopted by the Government in Malaysia in any structured way. The maintenance approaches adopted are mostly corrective which resulting poor service delivery, poor user satisfaction and endless maintenance backlogs. Thus, this paper aims to review the implementation of preventive maintenance and importance of routine maintenance frequency for the building facilities and services in high-rise residential buildings.
Design/methodology/approach
An extensive literature review published in between 1987 to 2016 has been carried out on the implementation of preventive maintenance strategy specifically routine maintenance. The building facilities and services which are divided into essential and value-added were identified and tabulated systematically to further form a theoretical framework to demonstrate the association between routine maintenance of building facilities and services and maintenance outcome.
Findings
The findings of the study argued that the routine maintenance might affect the maintenance performance. Future research is proposed to investigate the optimal frequency of routine maintenance to enhance maintenance performance.
Originality/value
This study identified the importance of routine maintenance by providing the classification of facilities and services, which fundamentally support future research to improve the maintenance management of high-rise residential building.

Abstract
Purpose
The purpose of this paper is to illustrate the maintenance prioritising for facilities services in high-rise residential buildings in Peninsular Malaysia. Maintenance prioritisation is becoming more prominent in the building maintenance industry due to budget constraints, poor maintenance management and to yield better maintenance performance.
Design/methodology/approach
Two main categories with eleven facilities services that require maintenance were identified through extensive literature review. A total of 321 returned questionnaires were analysed to distinguish the relationship between the maintenance priority and cost variance. Semi-structured interviews were then conducted to validate the findings.
Findings
The findings revealed that five essential facilities services were significantly correlated to cost variance and a regression model which examines the probability of over-budget was developed. Meanwhile, the interviews recognised that maintenance prioritisation has impact towards maintenance cost.
Research limitations/implications
This research focusses on the maintenance priorities of facilities services and their effects to maintenance cost. However, it is undeniable that the maintenance cost can be affected by other factors, contributing to a lower percentage of the total variance in the regression model. Thus, it creates research opportunity to study the factors (i.e. manpower, materials, wear and tear, etc.) affecting the variance of maintenance cost.
Practical implications
This study is useful to property managers in efforts to enhance the cost performance via appropriate maintenance prioritisation. The essential facilities services should be highly prioritised compared to the value-added facilities services.
Originality/value
The paper signifies the importance of maintenance prioritisation. It serves as a guide to plan and execute maintenance planning in a more logical way within budget and time constraints.

Abstract
Purpose
Augmented reality (AR) integrates the digital world with the real world and thus, provides a real-time experience to the users. With AR, the immediate surroundings become a learning platform for the users. The perception of the products has been enhanced many times with AR; thus, enriching user experience and responsiveness. The purpose of this paper is to bring forth the basics of AR and provide an overview of the research work carried out by researchers in the implementation of AR in different sectors.
Design/methodology/approach
This paper summarizes the usefulness of AR in different industries. The authors have identified the peer-reviewed research publications from Web of Science, Scopus, Google Scholar, etc. The selection of literature has been made based upon the significance of AR in recent times. The industries/sectors where AR has been implemented successfully have been considered for this paper. The paper has been divided into various sections and subsections to bring more clarity to the readers.
Findings
This paper presents a brief and a precise information on Industry 4.0 and AR. The basic working of AR system and its implications have also been discussed. The preference of AR over virtual reality (VR) has also been deliberated in this paper. The authors have presented the usefulness of AR in different sectors such as smart factories, ship yard building, online shopping, surgery and education. This paper discusses the AR-ready procedures being followed in these sectors.
Originality/value
AR has been an add-on to VR systems. The processes in industries have become very handy and informative with AR. Because the application of AR in different sectors has not been discussed in a single paper; thus, this work presents a systematic literature review on the applications of AR in different sectors/industries.

Abstract
Purpose
This study aims to show the relevance of augmented reality (AR) in mobile learning for the 21st century. With AR, any real-world environment can be augmented by providing users with accurate digital overlays. AR is a promising technology that has the potential to encourage learners to explore learning materials from a totally new perspective. Besides, the advancements made in information technology further broaden the scope for educational AR applications. Furthermore, the proliferation of wireless mobile devices such as smartphones and tablets is also introducing AR into the mobile domain.
Design/methodology/approach
This discussion paper gives an insight of the different potential fields of application of AR and eventually proposes an AR application that will give a completely different learning experience for learners. This AR mobile application will not only provide learners with supplementary information but will also assist lecturers in their teaching process. There are certain concepts in computer science at the tertiary level that are at times difficult for learners to understand using the traditional classroom approach. Through this AR application developed, the learners are able to see what is happening and experience a different form of learning where the focus is more on “learning by doing” and on the ability of visualizing the complete set of steps involved for a particular operation. Finally what is proposed is a generic framework/process for the development of AR applications for learning purposes.
Findings
The AR application developed and tested has proved to be helpful in understanding complex concepts of computer science that average students have much difficulty in understanding. Through AR, learning has been brought to a new dimension where the students can easily visualize what is happening and easily understand complex concepts. This low-cost system that has been proposed can track and detect both markerless and marker-based images. A number of experiments have also been carried out to determine a set of best practices for the development and use of such AR applications.
Originality/value
Learners have been able to have a more interactive and enriching learning experience through two-dimensional and three-dimensional digital augmentations. The AR mobile application has been enhancing the cognitive skills of learners through enabling them to scan images from printed materials with their smartphones. Then, informative digital augmentation has been overlaid in real time on the mobile screen with the image preview still in the background.
