Job burnout and work values as antecedents of organizational citizenship behaviours / Shaiful Annuar Khalid et al.

This study is conducted to examine the relationship between dimensions of job burnout, work values and organizational citizenship behaviour (OCB). Dimensions of burnout include cynicism, emotional exhaustion and reduced professional efficacy whereas work values consist of intrinsic work values and extrinsic work values. Two forms of OCBs tested are organizational citizenship behaviour directed at individual (OCBI) and organizational citizenship behaviour directed at organization (OCBO). The sample of this study includes 101 employees from several work divisions and levels of a Malaysian Multinational Corporation. It was found that dimensions of work values and burnout are significant factors to consider for enhancing OCBO. Specifically, the finding of this study demonstrates that intrinsic work values, extrinsic work values, emotional exhaustion and reduced professional efficacy are significant predictors of OCBO. However, only reduced professional efficacy significantly related with OCBI, whereas cynicism was not related with both types of OCB

Concrete-defect detection using new ultrasonic array

Concrete is the main component in construction of civil infrastructure. However, deformation in concrete such as crack or void may occur either on its early stage or during its usage. Hence, concrete evaluation is a need in determining its strength and quality status. Direct Ultrasonic Pulse Velocity (UPV) method is the most common non-destructive measurement adopted to assess the condition of concrete structure. However, problems arise when there is limited accessible surface to probe the ultrasonic transducers. Hence, this project is undertaken to analyse ultrasonic NDT by utilising different arrangement of sensors on tested concrete. The simulation of the homogenous and non-homogenous concrete system will be done by using COMSOL Multiphysics software. The output signal obtained from the simulation is used for the image reconstruction by using the sensitivity mapping technique. The results are then validated by assessing the actual model of concrete structure using direct, indirect, and semi-direct UPV probing in order to get the exact location of defects. Preliminary result shows that proposed method can help to improve the defects determination in concrete structure

NDT-defect detection on concrete using ultrasonic: a review

Non-destructive test (NDT) is widely used in industrial applications due to its reliability as well as flexibility. Rather than other methods, NDT is more suitable and practical to be performed in order to detect flaws and deterioration in concrete structures. This paper provides a review by studying various research works on concrete by performing ultrasonic technique NDT. In particular, the working principle of ultrasonic NDT, type of sensor and techniques adopted in ultrasonic NDT are briefly described in this paper. Further research based on preliminary data will be conducted to improve previous experimental work

The prevalence of obesity and the knowledge, attitude and practice of healthy lifestyle among the adult population in Kampung Banyuk, Kampung Kerto and Kampung Langup

Background Obesity has become a great public health concern and prevent!ive measures need to be done. Objective The objective of this research is to determine the prevalence ofobesity and their knowledge, attitude and practices (KAP) towards a healthy lifestyle among the residents in Kampung Banyok, Kampung Kerto and Kampung Langup. Methods A cross-sectional study was done among 126 randomly selected villagers aged 18 years and above from the three selected villages. They were interviewed based on a questionnaire and their body mass index (BMI) was calculated. Results It was found that more than half of the respondents are obese. Among the respondents, for the healthy lifestyle component, the level of good KAP is 69.2%, 46.8% and 60.3% respectively. As for obesity component, the level of good KAP is 60.3%, 54% and 54.8% respectively. Among the obese respondents, the level of knowledge and attitude on healthy lifestyle and obesity is better. Obese respondents have better obesity preventive practice while the non-obese respondents have better practice on healthy lifestyle. The only significant correlation noted was between knowledge and practice on obesity albeit a negative one. Conclusion The level of knowledge and attitude and practice on healthy lifestyle among the obese respondents are encouraged but more effort in the preventive practice ofobesity shou1d be done to reduce the prevalence.

Investigation of the chemical, strength, adhesion and morphological properties of fly ash based geopolymer-modified bitumen

The current study seeks to investigate the chemical, strength, adhesion and morphological properties of fly-ash based geopolymer-modified bitumen (GMB). The geopolymer was prepared by mixing class F fly ash with alkaline solution (sodium silicate and sodium hydroxide), and was then mixed with an 80/100 penetration grade bitumen at different concentrations of 3, 5, 7 and 9% (by weight of bitumen) to produce the GMB. The chemical and strength properties of the binders were determined using the Fourier Transform Infrared Spectroscopy (FTIR) and Impact tests, respectively. The Surface Free Energy (SFE) and Atomic Force Microscope (AFM) tests were conducted to establish the adhesion and morphology of the binders. The modification of base bitumen with geopolymer resulting the improvement in structural chain mobility properties and improved storage stability compared to those of the control sample. The result of FTIR analysis showed that the incorporation of geopolymer into base bitumen did not cause any change in the functional groups, where the peaks of aromatic Cdouble bondC stretching is at around 1600 cm−1 (stretch), 1475 cm−1 (stretch) and 900–600 cm−1 (out-of-plane bend). The peak at around 1390 cm−1 clearly shows the stretch of the C-N amine group. The result of SFE test shows that GMB has better resistance to moisture damage. Finally, the AFM analysis revealed morphological changes in all GMB samples. In general, the addition of 5% geopolymer can be considered as is the optimum concentration for bitumen modification
