Yeo Kee-Jiar , Lee Shih-Hui
Parents play a unique role in providing and facilitating their children in acquirement of sexual and reproductive health knowledge. The purpose of this study is to provide an overview of parents’ attitude, preferences towards sexuality education (SE) and factors that contributed to their attitudes and perceptions based on review of relevant literature. The articles were retrieved via electronic databases, and manually examined to identify the studies that addressed the research questions. There were 29 studies with a total of 22,213 parents involved which published in peer-reviewed journals between the year 2000 and 2018 were selected and reviewed systematically. The findings emerged from the review were categorized into three main themes which included parental attitudes, parental preferences towards the implementation of SE and the factors contributed to their attitudes and perceptions. Most studies revealed that parents showed positive attitudes and support the inclusion of SE in school. They preferred age-appropriated SE to be introduced in elementary schools and secondary schools. Some parents supported SE which is aligned with religious teaching and cultural. Demographic factors, parents’ sexuality knowledge, religious and cultural factors could affect parental attitudes and perceptions towards SE. This understanding could be useful for policymakers and educators to encourage collaboration with parents to strengthen the effectiveness of the program and scale up SE to benefit the young generation.

M.Z. Ismail , M.H.N. Talib , Z. Ibrahim , J. Mat Lazi , Z. Rasin
Fuzzy logic controller (FLC) has shown excellent performance in dealing with the non-linearity and complex dynamic model of the induction motor. However, a conventional constant parameter FLC (CPFL) will not be able to provide–good coverage performance for a wide speed range operation with a single tuning parameter. Therefore, this paper proposed a self tuning mechanism FLC approach by model reference adaptive controller (ST-MRAC) to continuously allow to adjust the parameters. Due to real time hardware application, the dominant rules selection method for simplified rules has been implemented as part of the reducing computational burden. Experiment results validate a good performance of the ST-MRAC compared to the CPFL for the   speed performance in terms of the wide range of operations and disturbance showed remarkable performance.

In combating COVID-19, maintaining the immune system is important. Providing this information to the general population will increase public awareness towards improving their immune system. The use of Google Trends for exploring web behavior related to a topic or search term also considered as a tool for monitoring public awareness to help risk communication during the COVID-19 pandemic. Therefore, this study was conducted to assess the use of Google Trends to monitor public awareness to immune system improvement during the COVID-19 pandemic in Indonesia. This quantitative and qualitative research used time-series data from 31 December 2019 to 2 May 2020. The time-lag correlation analysis was performed to compare between relative search volume (RSV) of “Vitamin C”, “Vaksin” (Vaccine), “Berjemur” (Sunbathing) from Google Trends (GT), and the number of reported COVID-19 new cases. Validation using time-lag correlation shows the significant correlation between RSV keywords related to public awareness towards immune system improvement and the number of COVID-19 cases in Indonesia in 1-3 days before an increase in the number of cases occurs. Google Trends has the potential to become an early warning system and a tool for monitoring risk communication towards immune system improvement during the COVID-19 pandemic by Indonesia Government.

Optical repeater for indoor visible light communication using amplify-forward method

10.11591/ijeecs.v20.i3.pp1351-1360
Arsyad Ramadhan Darlis , Lucia Jambola , Lita Lidyawati , Adisty Hanny Asri
In this paper, the implementation of an optical repeater for indoor visible light communication using the amplify-forward method was proposed. In indoor, visible light communication (VLC) can occur by transmitting information signals from lamps as a VLC transmitter toward the VLC receiver as line-of-sight (LOS) that is located with only a few meters. In the non-los (NLOS) communication, the signal will be attenuated, so it needs to amplify to improve good signal quality in a VLC receiver. The optical repeater could be used to improve the signal quality that attenuating due to distance. The audio signal was generated and sent using VLC Transmitter toward the light emitting diode (LED). Then, the electrical signal was converted to become visible light, and it was amplified using an optical amplifier with an amplify-forward method. The signal in the form of visible light that had been amplified would be received by the photodiode (PD), and the VLC receiver processed it. The measurement results showed the system that used the optical repeater could improving the distance until 9.5 m with frequency 6000 Hz, where the best signal quality at a frequency of 3000 Hz. The measurement result showed that the use of repeater components with the amplify-forward method for VLC systems, especially in the room, can increase the range until 4.5 m compare without an optical repeater. This result exceeds the minimum distance of an indoor visible light communication system, with an average distance of the roof to the floor is 3.5 m.

Obesity is a significant public health crisis affecting millions of children globally. The objective of this study was to identify the prevalence and associated factors of overweight/obesity among school children in Kinshasa, Democratic Republic of Congo (DRC). This was a descriptive cross-sectional study among school children and adolescents (n= 1442) from Kinshasa selected using multistage sampling method. A structured questionnaire was used to collect behavioral data. The WHO AnthroPlus was used to calculate BMI (body mass index). SPSS version 21 was used for data analysis. Potential covariates were examined using chi-square tests followed by multivariate logistic regression analyzes The study found that out of 1442 students, 72% of the sample was at a healthy weight, 15% were underweight and nearly 13% were overweight or obese. The prevalence of overweight and obesity was higher in girls as compared with boys. The results of multivariate logistic regressions showed that the gender of children, category of age, percent body fat, eating fruits and vegetables, and physical activity levels were significantly associated with childhood overweight/obesity. One in eight children and adolescents (12.8%) aged 6 to 18 years in Kinshasa going to primary and secondary schools were either overweight or obese.

10.11591/ijere.v9i4.20464
Johannis Takaria , Anderson Leonardo Palinussa
Mathematical self-concept (MS-C) is an important construct that prospective mathematics teachers must have in mathematics learning. The aim of the research was to analyze the increase of MS-C of prospective mathematics teachers. The research was quasi-experimental with the design of one group pretest-posttest. The results showed that for prospective teachers, MS-C increased in the medium category while the MS-C indicators achieved in the medium and low categories. The increase of MS-C is due to the effectiveness of collaborative mind mapping (CMM) learning strategy and the process of strengthening MS-C capacity of prospective teachers. The CMM facilitates prospective teachers to construct creative ideas through structured collective ideas that support the increase of MS-C among prospective teacher.

Optimized formation control of multi-agent system using PSO algorithm

10.11591/ijeecs.v20.i3.pp1591-1600
Ahmed M. Hasan , Safanah M. Raafat
Formation Control (FC) is an important application for Multi-agent Systems (MASs) in coordinated control and especially for Unmanned Aerial Vehicle (UAV) which are widely used nowadays in military and civil sections. FC is mostly applied in conjunction with consensus algorithm. In this paper, a framework for an implementation of consensus FC that involves the decentralized type of network control is considered in order to achieve  formation keeping, where the control of each vehicle is calculated dependent upon locally existed facts. The dynamic behavior of each vehicle agent is governed by its second-order dynamic model, and the networked mobile vehicle system is modeled by a directed graph. Then, particle swarm optimization (PSO) is implemented for speeding up the convergence to the desired geometrical shape. Acceleration of the network while approaching the coveted shape is achieved and omissions of undesired swing that transpires through the acceleration is examined. The merits and effectiveness of the applied approach are demonstrated using two different examples.
