To form the basis of the system development, a pre-survey questionnaire was conducted to find out customers opinion on static directories. The result of the survey showed that 70% or 35 out of 50 respondents know and understand the VR technology.The results of the analysis provide motivations for the development of the interactive virtual directory system The development of the system is based on the approach proposed by Kulwinder Kaur's design framework which will analyze the requirement and project scope, task and domain of the project, the designation of the environment, designation of user support and navigational tools and also evaluation by determine the prototype and iterative process. The results of an evaluation on the system shows that by having experience on both static and virtual map help user precisely understand the system. However if the mouse click application could be replaced with the touch screen application, it help user to navigate easily. In conclusion, a directory with additional functionalities could be an informative and more usable director

Android based application for monitoring patients health and medicine intake

The number of individuals who suffer from chronic disease continues to increase worldwide (WHO, 2015). Health awareness together with the improvement in living conditions and treatment has increased the life expectancy of people suffers from chronic disease; nevertheless without efficient health management and monitoring, the quality of life is decreased (Whitehead, Seaton, 2016). Progressive growth in computer-mediated technologies such as social networking, smartphones and medical applications provide a useful platform for self-health management and awareness. Towards empowering people in practicing self-health management, individuals who suffers from chronic disease need to have access to timely information, advice, assessment and treatment from medical practitioners in order for them to manage their long-term illnesses conditions systematically (Zoffmann et al. 2016). Medical practitioners play an important role in empowering self-health management by giving guidance, monitoring adverse events and identify areas for improvement while giving patients independently self-management their health (Whitehead, Seaton, 2016, Smith et. al, 2016). Through computer-mediated technologies, systematic intervention from medical practitioners and community is feasible thus improving quality of life for individuals (Lorig et. al., 2016)

Fe-doped TiO2 Nanoparticles Produced via MOCVD: Synthesis, Characterization, and Photocatalytic Activity.

Iron (Fe)-doped titanium dioxide (TiO2) nanoparticles were produced via the metallorganic chemical vapour deposition (MOCVD) method at 700∘C. Different amounts of ferrocene as the Fe dopant source (0.001–0.05 g) were introduced inside the reactor together with the titanium precursor in order to synthesize different Fe dopant concentrations of TiO2 nanoparticles. Nitrogen (N2) adsorption results showed that increasing the Fe dopant concentration caused a slight increase in the surface area of the nanoparticles due to the decrease in nanoparticle size. The UV-diffuse reflectance spectra demonstrated an absorption shift in Fe-doped TiO2 nanoparticles to longer wavelengths, thus showing an enhancement of the absorption in the visible spectrum. Bandgap energy values determined from the UV-diffuse reflectance spectra data decreased with an increase in the Fe dopant concentrations. The photocatalytic activity of Fe-doped TiO2 nanoparticles was investigated via degradation of methylene blue under UV and fluorescent light. It was found that Fe doping reduced the photocatalytic activity of the samples. Based on X-ray photoelectron spectroscopy (XPS) results, it is believed that this is due to the unfavourable location of Fe3+ inside the interior matrix of the TiO2 nanoparticles rather than on the exterior surface, which would affect photocatalytic behaviour

Effect of Postdeposition Heat Treatment on the Crystallinity, Size, and Photocatalytic Activity of TiO

Titanium dioxide (TiO2) nanoparticles were produced using chemical vapour deposition (CVD) at different deposition temperatures (300–700°C). All the samples were heat treated at their respective deposition temperatures and at a fixed temperature of 400°C. A scanning electron microscope (SEM), a transmission electron microscope (TEM), and X-ray diffraction (XRD) were used to characterize the nanoparticles in terms of size and crystallinity. The photocatalytic activity was investigated via degradation of methylene blue under UV light. The effects of post deposition heat treatment are discussed in terms of crystallinity, nanoparticle size as well as photocatalytic activity. Crystallinity was found to have a much larger impact on photocatalytic activity compared to nanoparticle size. Samples having a higher degree of crystallinity were more photocatalytically active despite being relatively larger in size. Surprisingly, the photocatalytic activity of the samples reduced when heat treated at temperatures lower than the deposition temperature despite showing an improvement in crystallinity

Knowledge about Aedes mosquitoes, dengue fever and zika virus among primary school students in the dengue cluster areas of Hulu Langat, Selangor

In Malaysia, dengue fever is a common vector-borne disease. Most cases of dengue fever are reported in residential areas. Children are at high risk to be infected because they spend a lot of time around their housing area for outdoor activities. Such areas may have a high number of Aedes mosquitoes. As schools are equipped with infrastructure and medium for effective educational purposes, schools represent the most suitable facilities for learning and teaching process. A crosssectional study was conducted to determine the level of knowledge among students in Hulu Langat on Aedes mosquitoes, dengue fever, and Zika virus. The study also reported on the demographic factors which affected the knowledge level. Based on sample size calculation using G*Power v3.1 software, a total of 171 respondents were needed from the two primary schools involved in the study. Data collection was conducted using a pre-tested questionnaire that consisted of two main sections on demography and knowledge about Aedes mosquitoes, dengue fever and Zika virus. From the total score of 55, the mean knowledge score is 34.2 ± 8.38. Based on the median value of 36.0, about 50.9% of respondents had satisfactory knowledge. From the study, it was found that students from School A, students who had been watching video related to Aedes mosquito, and those with history of dengue infection among family members had a significantly better knowledge score (p < 0.01). In conclusion, knowledge about Aedes mosquitoes and related illnesses need to be enhanced through a comprehensive module and effective educational materials that can serve as a reliable source of i nformation for primary school students

The Physical and Mechanical Properties of Compreg Laminated Bamboo Strips Lumber (LBSL) of <em>G. scortechinii</em>

The chapter explores the effect of resin concentration and pre-drying time on the physical and mechanical properties of compreg-laminated bamboo strips lumber (LBSL) from G. scortechinii species. The compreg LBSL panels were manufactured using two concentrations of low-molecular-weight phenol formaldehyde (LMwPF) resin, that is, 100 and 70% at three different pre-drying times (12, 18, and 24 h). Based on the findings, the panel with 70% of LMwPF required a longer time and higher temperature to cure than the panel with 100% LMwPF. The weight percent gain (WPG) and moisture content of the panels increased in line with increasing resin concentration but decreased with increasing pre-drying time. The opposite trend is indicated by density. As for the mechanical properties, the strength of the panel increases along with the increase in resin concentration and pre-drying time. However, for high-concentration resins, prolonging the pre-drying time reduces the strength of the sample. The highest flexural strength and tensile strength were observed in the 100/18 sample with values of 260 and 27 MPa, respectively. The results for formaldehyde emissions show panels with lower resin concentrations: 70% LMwPF and prolonged pre-drying time reduce formaldehyde emission levels
