The objective of this research is to investigate on the thermal comfort condition of low-cost multi-storey residential building located in the urban area in Malaysia. This study began with the selection of six-storey apartment blocks located in Section 7, Shah Alam as the case study project. Then, data in form of thermal comfort elements and building elements were collected from 47 apartment units from 23rd of November 2010 to 2nd of December 2010 at two (2) different time intervals, i.e. afternoon and evening. Data of these two parameters were then cross-tabulated using SPSS and described in terms of mean or average value of dry-bulb temperature, relative humidity and air velocity. These values were further summed up in a table to indicate minimum and maximum measures only. They were then compared with the current thermal comfort standard as well as precedent studies on the subject. Finally the results indicated that the thermal performance of urban low-cost apartment in Malaysia is still within the comfort range. However this condition can be further improved should the recommendations suggested being considered and implemented in future low-cost housing development in Malaysia.

Globally, logistics is an important economic activity valued at about USD 320 billion a year and growing at an annual rate of 3 to 10 percent. Malaysia has recognized the industry as the main key towards enhancing Malaysia's progress on becoming a globally competitive fully developed nation. It was predicted that the logistics industry would grow at 8.6% during the year 2006 – 2020 plan period and contribute 12.1% to Growth Domestic Product (GDP) by 2020. Therefore, the development of the human capital or human resource for the logistics industry in Malaysia becomes important in confirming the nation's competitiveness. Accordingly, the aim of this study is to produce a feasible framework of human-resource development for the logistics industry in Malaysia.

Recreation ecology research was widely conducted to analyze data on factors that influence nature trails condition. Protected area such as Imbak Canyon Conservation Area (ICCA) was established because of its outstanding natural area and its potential of providing outdoor recreation experience to visitors. However, recreation use is also one of the major threats to protected areas. This study addresses the impact of recreation use by conducting a trail assessment exercise to several major trails in ICCA. The assessment of current trails condition will later be use as a benchmark for trail use in ICCA. This preliminary assessment shows that even with a very low number of usages during the expedition, there are evidences of potential threats to the trail conditions, visitors experience and natural condition of the area.

The conversion of fly ash into zeolites has become an important waste management issue in recent years. Zeolites may be easily obtained from fly ash by the relatively cheap and fast hydrothermal conversion process. Raw fly ash is pretreated with hydrochloric acid at the determined optimum pre-treatment temperature, time and ratio of 80°C, 1 hour and 25∶5 (ml/g), respectively. Zeolite was then synthesized by mixing the pretreated fly ash with sodium hydroxide solution in a ratio of 150 g∶ 300 ml at various reaction temperatures: 90, 150, 210 and 350°C. XRD analysis of the fly ash with treatment and the structure of the as-synthesized zeolite indicates little change in the crystalline structure of the fly ash, although peak intensities of most components appear to decrease with increasing synthesis temperature. Evaluation of the particle size distribution of the zeolite material indicates that at higher temperatures a bimodal distribution and improved particle size uniformity manifest. In conclusion, the best zeolite material was obtained at 350°C.

Global energy demand especially natural gas is expected to grow due to high world oil prices. Natural gas composed mostly of methane is the cleanest burning fossil fuel. Thus, offering an alternative fuel and at the same time has ability to reduces the environment impact. LNG carrier has been successfully used to transport this fuel across the globe, despite being complex, expensive and potentially hazardous cargo. However, there is some area need to pay more attention in order to reduce the overall costs of this carrier.

Fe-Cr matrix composites reinforced with Al2O3 particulates fabricated by powder metallurgy (PM) method offer potential for cheaper wear resistance materials and high temperature application. The influence of Al2O3 amount on densification, micro-hardness, wear resistance and strength of the composites were evaluated. The results showed that Al2O3 yield good influence on Fe-Cr matrix composites. Increases the amount of Al2O3 to more than 5 wt% decreases composite's relative density. The micro-hardness and wear resistance of the composites improved with increasing amount of Al2O3 to 20 wt%. Beyond 10 wt% Al2O3 addition, the strength properties began to decrease with an increase in Al“2”O3 addition. Overall, the composites reinforced with 5 wt% Al2O3 exhibited the best results.

This article reviews several methods of calculating solar radiation from satellite derived earth atmospheric reflectivity from the visible channel. Most models calculate global and direct beam solar radiation on daily and hourly basis. Statistical models do not require precise information on atmospheric parameters whereas physical models apply these atmospheric parameters. These later evolved where authors developed hybrid models combining both. Despite a considerable number of publications which use satellite data to derive solar radiation, many models were modified and improved from existing models which were considered popular models. These popular models are briefly reviewed in this article. Most models were developed for the North American or European climate except for the physical model of Janjai et al 2005, which considered the tropical climate and the Brazillian Solar Radiation model. The models estimate hourly global solar irradiation with a RMSE between 6.8% and 25.6% while the daily global solar irradiation RMSE is between 12.9% and 18.13%.

E-Learning tools have been recognized as one of the most important tools to facilitate learning in tertiary education. However, in recent years it has also evolved as a multitasking tool to promote asynchronous learning among students. Malaysia as an education hub regularly draws large numbers of foreign students to pursue transfer degree programs here. It is observed that these students from various continents of the world have different perceptions on learning due to their cultural differences. Therefore, an e-learning platform is required to facilitate asynchronous learning. This paper explores the transfer students' usage pattern of a typical e-learning tool: Course Management Software (CMS) or commonly known as Blackboard in tertiary education. Though e-learning have provided fascinating multitasking tools, very limited attention is paid to transfer students' perceptions and the frequency of usage of the e-learning system. Therefore, a case study was conducted in an e-learning environment, on the usability of selected tools in CMS. Results of the research demonstrated that large percentage of students had very positive perceptions of certain e-learning tools and the frequency of usage of CMS is high; with vast majority of students using it frequently. Nevertheless, the findings also suggest that certain tools are redundant and do not assist in their learning process. Some implications of the findings are discussed in this paper.

Corruption in construction is a fiduciary crime that is believed to slowly penetrate the construction sectors in countries around the world. It that can reduce the efficiency, effectiveness and equity of infrastructure services that resulted in construction projects that is unnecessary, unsuitable, and defective. In order to control effectively the level of corruption in construction, the critical factors of corruption in construction need to be correctly diagnosed. Hence, the objective of this paper is to review the critical factors of corruption in construction by various researchers across the globe. The initial findings based on purely literature reviews suggest that critical factors could be divided into direct and indirect factors that affect the supply and demand for corrupt activities. Meanwhile, environment, individual and international firm factors are also seen to be critical. Individual attitude, laws and regulations and administrative control are also imperative factors critical to corruption in construction.
