AbstractThe Philippines is one of the countries that experience hot weather throughout the year and are exposed to negative effects of heat. This study focuses on alleviating the heat experienced indoors by reinforcing chicken feathers to your normal cement mixture. The reduction of the heat experienced indoors will lead to cost savings for if the surrounding temperature indoors is cool enough, one will not have to use an air conditioner or even an electric fan. Related studies about heat, insulation, cement, and the uses of chicken feathers in various industries also became the support and basis in pursuing this study. The researchers aimed to produce a cement mixture with chicken feathers that will effectively insulate a structure. Comparison between the temperature inside the cement model with the commercially available cement mixture and the ones with whole and cut feathers were made. Its thermal properties were tested by exposing the wall models to a controlled environment with four lightbulbs surrounding it. The temperatures were obtained using the Extech HT30: Wet Bulb Globe Temperature (WBGT). The researchers used ANOVA to analyze the given data. Focusing on the main objective, the researchers analyzed the results from the cement blend type. Having the p-value of 0.15 be greater than alpha which is 0.05, the researchers have accepted its null hypothesis wherein the type of blend does not have an effect on the mean temperature difference between the side without the light bulb and the side with the light bulb. Nonetheless, based on the data gathered, the blend with 5% whole chicken feathers insulated the box well

Abstract
Nowadays the natural slope cuts for the purpose of the construction of public transport is ubiquitous in Malaysia. These cuts cause the changes of the natural slope structure thus make the slope structure become unstable and causes to rubble. In order to avoid the slope’s failure, the monitoring work on slope should be carried out by the responsible party to ensure that the slopes are in good condition and the advance warning can be issued before the occurrence of the rubble. Conventional method of slope monitoring is extremely high risk. Usually, maintenance personnel will climb up to the top of the slope to take pictures for the purpose of monitoring reports [1]. Slope monitoring activities are also limited as climbing steep slope structures require a lot of energy and takes quite a while. Therefore, this research aims to explore the ability of the micro UAV aircraft usage in order to monitor the slope condition. The aim of study is to monitor the high risk slope using UAV. To achieve the aim, the following objectives are formulated by produce orthomosaic image, Digital Terrain Model (DTM) and Digital Surface Model (DSM) using pix4d mapper software, analysis the image of drainage system taken by UAV and developed contour of the slopes and analyse watershed of the slope using global mapper software. In this paper, the drainage on the slope becomes the focus since its plays an important role as it reduces the existence of groundwater and to transport the rainwater pours on slope surface. The study was conducted at two places where first at Kuala Pilah Federal Route 361 and second at Jalan Bangi Selangor State Route B17. The processes involved were planning and preparation before flight, data retrieval using UAV aircraft, image processing using Pix4dmapper software and assessment of the slope using Global Mapper software. Subsequently, the slope condition can be determine based on the monitoring of the slope drainage. Through this study, the condition of slope surface can be seen by images taken from UAV such as cracking on slope structure and excessive vegetation growth in slope drainage. Besides that, the slope inclination, height and water flows on surface can be known. Therefore, the usage of UAV aircraft for slope monitoring and inspection was successfully and the aims of this paper was achieved since the device shows a very good tendency and the ability to monitor the slope condition.

Abstract
Heat Ventilation Air Conditioning System (HVAC) is designed to control the environment inside of residential, commercial or industrial buildings by controlling temperature of a room through heating and cooling. However, due to its mechanism, noise is produced in the system and reaches the people inside the building, thus causing distraction, discomfort and uneasiness. There are HVAC silencers in the market; however, the sound absorbing material used is of mineral wool types. In this study, the ducting silencer with the sound absorptive material that made of Arenga Pinnata, Kenaf and composition of these both materials were tested to identify its performance. The experiment was carried out in a testing apparatus that follows the ASTM E477-99 standard. Insertion loss was analysed at the end of the study. From the overall result and comparison, the insertion loss of Kenaf is averagely better than Arenga Pinnata, that is 97.5% higher than Arenga Pinnata. When composition of Arenga Pinnata and Kenaf is used, Kenaf plays important role in sound insertion loss, where when Kenaf composition increase, it increases the sound insertion loss capability.

Abstract
This study proposes a novel technique to convert local iron ores into industrial grade red colour pigments. The methods employed in this work include high-energy milling, ball milling, rod milling and high-energy blending. It was observed in the TEM results that high-energy milling using ø 3 mm balls running at 550 rpm produced the finest particles with a value of 73.13 nm and a specific surface area of 178.62 m2g−1, while ball milling and high-energy blending methods were similarly effective in producing nanoparticles with size of78.54 nm and 88.65 nm, respectively. The sample of high-energy milling at 550 rpm displayed noticeable alterations in colour values, but the lightness of high-energy blending samples was low in comparison to other methods. CIE L*a*b* colour values were analysed for all the samples and the results indicated that the value of a* for all the samples was greater than 18.0. This indicated that the samples are suitable for use as raw materials in red colour pigment production. Generally, the processing speeds utilized by the above mentioned methods resulted in significant changes in colour properties and its microstructure.

Abstract
A brain tumor is defined as a mass of tissue formed by an accumulation of abnormal cells within the brain. This paper proposes a high gain ultra-wideband (UWB) reflector array antenna for cancer detection. Introduction of the copper reflector with ideal distance contribute to increasing the proposed antenna gain. The antenna is printed with 4×1 copper radiating patch array properly connected with quarter wave transformer transmission line associated with a copper parasitic element for the front side. The patches comprise of four identical circulars with a diameter of 15 mm. Parasitic element is placed on very close to feeding line with the gap only 0.2 mm. Each quarter wave transmission line has its own specific wide dimension for 50Ω, 70.71Ω and 100Ω to ensure equal current distribution towards all four patches could be realized. Quarter-wave transformers of 70.71 Ω are used to have an ideal match between the 100 Ω lines and the 50 Ω lines. The high gain antenna is essential in a human microwave detection system for penetrating the multilayer structures by enhancing the focus of the electromagnetic energy into the desired structure. The antenna with reflector recorded wider bandwidth; 1.6 GHz-10.8 GHz associated with higher gain ranged from 3.2 dB until 14.1 dB compared with an antenna without reflector operated from 2.2 GHz to 10.8 GHz with lower gain ranges of 2.1 dB to 10.2 dB.

Abstract
This study was conducted to produce empirical evidence of validity and reliability of a set of questionnaire. Questionnaire drawn from the results of previous studies and the validity of the tests will determine whether all aspects of the construct domain were represented, thus ensuring the high objectivity level of the questionnaire. In addition, an alternative approach was used to assess the discriminant validity, using heterotrait-monotrait ratio of correlations. The study empirically proves that the questionnaire used is unchanged by culture. This is important because if not, its use will be restricted to a population in which the questionnaire was developed. The proposed method is better in which to enhance and improved the discriminant validity, using heterotrait-monotrait ratio of correlations. The results of the analysis in the measurement model indicated that the questionnaire meets the standards of reliability and construct validity.

Abstract
Teaching is a complicated and comprehensive task. Teachers may spend many years of practice to learn how to teach well, and most of us will not have learned enough. It would be a continuous process to be a good teacher. Instead of keeping on learning what we do not know about teaching the subject, it is better to know what the real problems are happening in the class, reflect what is the cause and come out with an action plan as nobody starts well at teaching. Furthermore, in fulfilling the worldwide demand for Mandarin language acquisition occasioned with the advance affordances of technology, most of the researchers focused on technology impact than the pedagogical aspects. And there is still too little action research regarding teaching pedagogy that has been done on enhancing Mandarin learning, especially in the local context. Thus, it is the right time the researcher cum instructor examines Mandarin pedagogical practice through individual action research to examine to what extent technology-enhanced Mandarin instruction could impact teacher’s pedagogical practice besides assisting students’ learning. A total of fourteen Mandarin non-native learners have participated in the study. The triangulation method was used to ensure the trustworthiness of this qualitative study. The data was collected through students’ diaries, reflective journals, focus group interviews and oral assessment. Then they were analyzed through content and thematic analysis to ascertain the themes regarding teacher pedagogical practice which influenced smartphone usage in Mandarin learning. The results revealed that the human aspect was the most crucial factor in ensuring the success of technology integration instruction. The smartphone was found as a promising tool in teaching Mandarin however it is only effective when teachers use it as a pedagogical tool effectively.

Published: June 2020

Abstract
Quality of e-service is one of the critical factors that decide the success or failure of organizations. It may increase competitive advantages as well as enhance the relationships with the customers. Achieving high e-service quality and user satisfaction are challenging since they depend fundamentally on user perception and expectation which can be tricky at times. To date, there is no agreement as to what service quality is, and how it should be measured, whether it is a function of statistical measures of quality including physical defects or managerial judgment, or it is a function of customer perception about the services. This paper deep-dived the quality of e-services offered by five Malaysian Institutes of High Learning (IHL) including two private and three public universities. A quantitative approach was utilized to collect the data and AMOS 21 was used to analyze the data and develop the measurement model. The paper aims to find the relationship between e-service quality dimensions and the user satisfaction by using Conformity Factor Analysis (CFA) test with 320 students in the target universities. The research results indicated that the measurement model has acceptable values and the Structural Equation Model (SEM) has positive impact on the relationship between e-SQ dimensions and user satisfaction. Achieving high user satisfaction can enhance the competitive advantage of the universities in their respective target markets.
