Investigating factors for disaster preparedness among residents of Kuala Lumpur

The review of past researches discussed that factors such as climate change and movement toward urbanization will result in more frequent and severe disasters in the near future (Yasuhara et al., 2011). Flash flood is the most common type of disaster that residents of Kuala Lumpur (KL) come across, thus in this study, it was desired to discover the factors affecting preparedness among residents of KL as well as assessing the variation of individual preparedness among residents. With the aid of SPSS analysis, the reliability of data, correlation and regression analysis between the investigated factors and disaster preparedness were obtained. According to this research it was found that level of preparedness of residents of KL is still below average; majority of social demographic indicators such as income, education, age, and property ownership showed significant contribution to the variation of disaster preparedness among the residents. For instance men were much more prepared in comparison to women; residents with high level of income and education had also significantly higher preparedness compared to those with low level of income and education. Race was the only factor that differs from the findings of previous studies; since race does not affect the preparedness

The FE, which is assumed to take regular shape, is considered in each section of the device. Simulation result show that FE has a significant effect on the output power especially when it occurs in coupling regions

IMPAK MEDIA SOSIAL TERHADAP TINGKAH LAKU SOSIAL PELAJAR DI KOLEJ VOKASIONAL

Social media networks have created a phenomenon on the internet that helps maintain relationships with other users. However, in recent times there are a handful of teenagers who are too obsessed with the use of social media that result in the phenomenon of social media addiction. Therefore, this study is conducted to examine the impact of social media on student's social behaviour in vocational colleges. The study was quantitative. The sample of the study consisted of 345 vocational college students. The research instrument involved a set of questionnaires that contained 41 items and used the Likert scale as a measure. The mean score analysis and standard deviation are used to see the purpose of using and the impact of social media among students. T-test is used to see the impact of social media impact on gender-based social behaviour. There are social media effects on students such as wasting time, depression and stress as students are exposed to immoral videos and pictures. Furthermore, there was no significant difference in the impact of social media on students based on student gender based on t-test. In conclusion, social media has had a negative impact on the students. Thus, high awareness needs to be applied to students to curb social behaviour problems

Surveillance and Protection-Based Approach for Link Failures over Fiber-to the-Home (FTTH) with Combination of ACS and SANTAD

This paper introduces an in-service transmission surveillance and protection-based approach for fiber failures/faults over fiber-to-the-home passive optical network (FTTH-PON) with an excellent combination of Access Control System (ACS) and Smart Access Network Testing, Analyzing and Database (SANTAD). Our hardware design works on a standard local area network (LAN) using a specially designed hardware interfaced with a microcontroller integrated Ethernet to monitor the status of optical signals flow and provide the restoration against fiber failures/faults in FTTH-PON. We also introduce the centralized management and access control program by means of SANTAD. ACS is used to control the troubleshooting mechanism carried out by SANTAD. This design will be implemented at central office (CO) for distant monitoring and remote controlling each optical fiber line's status as well as for detecting any failures/faults that occurs in the network system downwardly from CO towards multiple optical network units (ONUs). The scope of this discussion only highlighted on the monitoring and controlling instead of the restoration scheme

Ricketts’ Cephalometric Analysis for Saudi Population

Objective: To evaluate the cephalometric norm for Saudi sample by Ricketts analysis (RA). Material and Methods: In this cross-sectional study, cephalometric radiographs were taken for 500  samples. The subjects included 250 males and 250 females. The ages of the subjects ranged from 18-30years. The criteria of selection were based on Class I incisor relationship, no skeletal abnormality and no previous orthodontic treatment. Lateral cephalometric radiographs were taken, traced and digitized by SPSS software, according to RA. An independent t-test was used to test the level of significance between genders.  Results: Significant disparities found between Saudi males and females in dental and soft tissue measurements. The result showed that the distal position of the maxillary first molar to pterygoid vertical plane (U6 to Ptv) measurement was highly significantly greater (p<0.001) in Saudi males than females. Lower incisor to A- Pog (L1 to A-Pog) and lower lip to E plane was significantly longer (p<0.05) in Saudi males than females. Other measurements had no significant difference between Saudi males and females. Conclusion: The craniofacial morphology of the Saudi males was different from Saudi females using Ricketts analysis. This study will help the clinicians to diagnosis and treatment planning of orthodontic and orthognathic patients

Optical Channel Capacity Upgrade Based on Multiwavelength Conversion XGM Using Semiconductor Optical Amplifier for Access Networks

This paper demonstrates a 10 Gb/s one-to-two-wavelength conversion configuration based on cross-gain modulation for optical access networks using a single TW-SOA. The method is capable of converting a signal data of specific wavelength 1541 nm to certain wavelengths of CW’s laser 1554 nm and 1558 nm with 4 nm spacing. The pump power level was classified due to channel response. A result obtained was the best power level offering wavelength converter between −6 and 3 dBm. The conversion efficiency achievement provided an acceptable result for probe signals. The findings of Q-factor performance were investigated. The Q values were found to be more than 9 for point to point transmission and 20 km fiber configurations for the original and converted signal. The technique implemented at 20 km and the power of all channels were adequate to provide a splitting ratio of 1/64 for the launched pump power 3 dBm
