Abstract

Purpose

The purpose of this paper is to establish the impacts of good maintenance work for heritage buildings in Malaysia. This purpose is achieved through identifying factors that lead to the lack of maintenance of heritage buildings, establishing strategies to overcome the lack of maintenance of heritage buildings and analyzing the impact of good maintenance work on heritage buildings in Malaysia.

Design/methodology/approach

A quantitative method was employed for this study to identify the variables that most influence the maintenance of heritage buildings in Malaysia. The respondents were the owners of the heritage buildings in Peninsular Malaysia. There were 65 owners of heritage buildings identified from the official website of the Department of National Heritage, Ministry of Tourism and Culture, Malaysia. Simple random sampling was used to obtain the sample size of the targeted respondent. A total of 56 questionnaire surveys were distributed to the owners of heritage buildings. In total, 37 respondents returned the completed questionnaires, resulting in a response rate of 66 percent. The data were analyzed by Descriptive Statistics using Statistical Package for the Social Science software version 20.

Findings

Results show that the factors that lead to the lack of maintenance of heritage buildings are limited finance, the absence of maintenance guideline and ill-defined maintenance policy. The strategies to overcome the problem include providing a financial budget by the respective authorities, establishing a standard maintenance guideline and revising the existing policy.

Research limitations/implications

The paper is limited to the identification of factors that lead to a lack of maintenance and strategies to overcome the problem for the heritage buildings in Malaysia. The respondents are the owners of heritage buildings in Malaysia. The focus is given to them due to the fact that it will help them in understanding the importance of managing and operating for their buildings.

Practical implications

The results offer value-added information to building managers who are responsible for maintaining heritage buildings. Findings show that good maintenance work on heritage buildings can enhance the value and safety of the building as well as preventing heritage buildings from deteriorating.

Social implications

The quality of maintenance could be enhanced by focusing on the important variables that affect the quality of maintenance works of heritage buildings.

Originality/value

Limited studies had been carried out in the context of the maintenance of heritage buildings, especially in Malaysia.

This paper aims to study the anti-diabetes activity of the Kombucha prepared from different snake fruit cultivars.

Abstract

Purpose

This paper aims to study the anti-diabetes activity of the Kombucha prepared from different snake fruit cultivars.

Design/methodology/approach

The juices of snake fruits of Suwaru, Madura, Pondoh and Bali cultivars were fermented for 14 days. Anti-diabetes activity of the products was analyzed. Twenty-four male albino Wistar rats were used and randomly divided into six experimental groups, i.e. four groups of the diabetic rats treated with the Kombucha, plus the normal group and diabetic control group. The Kombucha were orally administered to the streptozotocin induced-diabetic rats at 5 mL/kg body weight per day during the 28-day experiment. The fasting plasma glucose (FPG), oxidative stress indices (superoxide dismutase [SOD] activity and Malondialdehyde [MDA] level) and lipid profile of the blood plasma were measured. The pancreas was used for immunohistochemical study and β-cells quantification. Data were analysed by ANOVA followed by Fisher test using Minitab version 16.0.

Findings

FPG of the diabetic rats treated with the Kombucha (110.3-189.3 mg/dL) was significantly lower (p = 0.000) than the diabetic control group (413.3 mg/dL). Those were in line with the number of pancreatic β-cells of 42.1 in diabetic rats that lower (p = 006) than those in treated the diabetic rats (61.2-73.5). The treated diabetic rats had lower oxidative stress (SOD activity: 20.9-44.6 unit/100 µL with p = 0.000; MDA level: 0.37-0.48 ng/100 µL with p = 0.000) than those in the diabetic rats (SOD activity: 18.7 unit/100µL; MDA level: 0.84 ng/100 µL). The treated diabetic rats also showed better lipid profile than those in the diabetic control rats. There were cultivar differences, and the Suwaru and Madura snake fruit Kombucha demonstrated the most potential for diabetes management.

Originality/value

This is the first study on in vivo anti-diabetes activity of snake fruit Kombucha prepared from different snake fruit cultivars.

Abstract

Purpose

The purpose of this paper is to identify the most influential buildings elements in term of the cost for timber restoration works.

Design/methodology/approach

The research employed the case studies methods with questionnaires surveys. Two case studies were chosen and questionnaire surveys were distributed to contractors and consultation companies. The cost was identified based on the elemental cost analysis of historic timber buildings.

Findings

The restoration of historic timber buildings in Malaysia has grown rapidly, especially in the UNESCO world heritage sites, Melaka and Penang. Data obtained on the restorations of timber buildings show that the most influential elements were upper floors, roofs and walls. Termites’ invasions and the lack of building analysis were found to be the major issue in timber restoration works. In addition, the availability of timber material contributed significantly to the increase of cost for restoration works.

Originality/value

The cost for every element was identified and was used as a reference for new restorations projects of historical, timber buildings. This paper also highlighted the causes for the problems and the factors affecting the cost of timber restoration works. These data are useful information, especially for surveyors and contractors who are involved in the restoration of historic timber buildings. Maintaining or replacing these elements with other material can help to minimise the restoration cost of timber buildings in Malaysia.

Abstract

Purpose

Conflict was recognized as a major cause of inefficiency and limited performance of construction projects. Factors pertaining to conflict in construction are vast; however, there have been less recognition of these factors in international construction projects. The purpose of this paper is to provide in-depth understanding of conflict in this context and analyze how it influences project performance.

Design/methodology/approach

A questionnaire survey was used to collect data from 161 professionals working in Malaysian companies, which are undertaking construction projects overseas.

Findings

Analyzing the data using factor analysis revealed six new factors of conflict: external, internal, control-related, knowledge-related, mismanagement, and social conflicts. Further analysis of the data using partial least squares-path modeling (PLS-PM) affirmed a significant relationship between project performance and two factors of conflict only: internal and social. The results also showed that conflict contributes to about 27 percent of the variance in project performance.

Originality/value

This paper provided a clear picture for project managers and team members about specific aspects of conflict and how to mitigate them to attain better performance of international construction projects.

Abstract

Purpose

Heritage buildings, as any other buildings are subject to decay and deterioration. This issue increases significantly when a country undergoes complicated circumstances of unrest, as is the case in Iraq. The purpose of this study is to rethink the maintenance approach to heritage buildings in Iraq from a systematic management standpoint. It proposes the development of a management system through the functions of proper planning, organizing, directing and controlling. The study aims to scrutinize the weak areas of performance in the investigated work process in Iraq and provide suggestions to address them.

Design/methodology/approach

The paper opted for an exploratory study, using interviews with responsible people in Iraqi heritage buildings administration to investigate the procedures applied on maintenance work for the heritage buildings. Besides, maintenance reports were reviewed and three case studies of buildings recently assigned for maintenance were visited and examined to identify the current course of actions at work and to uncover the points of weakness and strength.

Findings

The researchers identified a kind of unreal planning in the maintenance process, which appeared to be a manifestation of corrective maintenance (CM) rather than a preventive one. Such an aspect was highlighted due to several causes, among which most important were as follow (1) the lack of sufficient allocated budgets and (2) the shortage of hand labor and building technicians in this field, including professionals with an architectural training background, who could make practical choices to heritage maintenance thus preventing improper solutions that would harm the authenticity of the asset. Such factors could be mitigated if a good maintenance management system is to be adopted. A proposed system is hereby suggested, upgrading the current guideline and laws by the specialized authorities in addition to recommending the application of digital documentation.

Originality/value

This paper fulfills an identified need to study how maintenance management system can be applied for heritage buildings
