As an economy with archipelago contour and one of the largest populations in the world, Indonesia faces specific challenges in utilizing ICT for education nationwide. The present study provides a systematic categorization of such challenges into four categories based on Kim YoungHwan’s categorization of ICT utilization challenges, and then breaks down such categories into more explanatory sub-categories, along with order of frequency. Hence, this study aims at systematically describing challenges in utilizing ICT in Indonesia.
Why was the 2008 Indian Ocean Dipole a Short-lived Event?
Iskhaq Iskandar,Muhammad Irfan,Fadli Saymsuddin 한국해양과학기술원 2013 Ocean science journal Vol.48 No.2
In this paper, the role of equatorial oceanic waves in affecting the evolution of the 2008 positive Indian Ocean Dipole (IOD) event was evaluated using available observations and output from a quasi-analytical linear wave model. It was found that the 2008 positive IOD was an early matured and abruptly terminated event: developed in April, matured in July, and diminished in September. During the development and the maturation of the 2008 positive IOD event, the wind-forced Rossby waves played a dominant role in generating zonal current anomalies in the western equatorial Indian Ocean, while a complex interplay between the wind-forced upwelling Kelvin waves and the eastern-boundary-generated Rossby waves accounted for most of the variability in the eastern basin. The latter induced eastward zonal current anomalies near the eastern boundary during the peak phase of the event. The 2008 positive IOD event was abruptly terminated in mid-July. We found that there were strong eastward zonal currents in mid-July, though the surface wind anomalies in the eastern basin continued to be westward (upwelling favorable). Our analysis shows that these eastward zonal currents mainly resulted from the easternboundary-generated upwelling Rossby waves, although the contribution from the wind-forced downwelling Kelvin waves was not negligible. These eastward zonal currents terminated the zonal heat advection and provided a favorable condition for surface heat flux to warm the eastern basin.

Multi-functional voltage source inverters (VSIs) have attracted increasing attention in recent years for their advantageous auxiliary services for power quality enhancement in autonomous microgrids. These types of VSIs can not only achieve a proper control scheme in autonomous mode but also cope with the prescribed power quality and stability requirements. These functionalities are integrated within the same device, thereby significantly improving the cost-effectiveness of microgrids while decreasing the investment and bulk compared with those of multiple devices with independent functionalities. Control strategies for power quality enhancement in autonomous microgrids using multi-functional VSIs are comprehensively reviewed in this paper. In addition, such VSIs are discussed in detail, and comparisons of which are also provided. Lastly, a number of future research directions for multi-functional VSIs are recommended.

( Shahid Anwar ),( Mohamad Fadli Zolkipli ),( Vitaliy Mezhuyev ),( Zakira Inayat ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.6
Botnets have become one of the most significant threats to Internet-connected smartphones. A botnet is a combination of infected devices communicating through a command server under the control of botmaster for malicious purposes. Nowadays, the number and variety of botnets attacks have increased drastically, especially on the Android platform. Severe network disruptions through massive coordinated attacks result in large financial and ethical losses. The increase in the number of botnet attacks brings the challenges for detection of harmful software. This study proposes a smart framework for mobile botnet detection using static analysis. This technique combines permissions, activities, broadcast receivers, background services, API and uses the machine-learning algorithm to detect mobile botnets applications. The prototype was implemented and used to validate the performance, accuracy, and scalability of the proposed framework by evaluating 3000 android applications. The obtained results show the proposed framework obtained 98.20% accuracy with a low 0.1140 false-positive rate.

Stevens-Johnson syndrome (SJS) produces a severe hypersensitivity reaction caused by Herpes simplex virus or mycoplasma infection, vaccination, systemic disease, or other agents. Several studies have investigated the genetic susceptibility involved in SJS. To provide further genetic insights into the pathogenesis of SJS, this study prioritized high-impact, SJS-associated pathogenic variants through integrating bioinformatic and population genetic data. First, we identified SJS-associated single nucleotide polymorphisms from the genome-wide association studies catalog, followed by genome annotation with HaploReg and variant validation with Ensembl. Subsequently, expression quantitative trait locus (eQTL) from GTEx identified human genetic variants with differential gene expression across human tissues. Our results indicate that two variants, namely rs2074494 and rs5010528, which are encoded by the HLA-C (human leukocyte antigen C) gene, were found to be differentially expressed in skin. The allele frequencies for rs2074494 and rs5010528 also appear to significantly differ across continents. We highlight the utility of these population-specific HLA-C genetic variants for genetic association studies, and aid in early prognosis and disease treatment of SJS.

Background and Objectives: This study aims to compare the characteristics, effectiveness and results of transcatheter closure of atrial septal defect between children, adolescents, and adults. Subjects and Methods: In this study, 683 patients who underwent atrial septal defect closure in the last 10 years were divided into three groups: children (age <12), adolescents (age 12 to 16), and adults (age >16) as group 1, group 2 and group 3, respectively. Results: The average defect size and incidence of complex atrial septal defect were higher in group 3 (p=0.0001 and 0.03 respectively). While the average size of the devic was higher in adults (22.6±6.4 mm vs. 18.5±4.9 mm; p=0.0001), the ratio of the device size/total septum was higher in both children and adolescents (Group 1 and 2). In the child and adolescent groups and patients with only complex atrial septal defect, the use of techniques, other than standard deployment, was similar in all three groups (p=0.86 and 0.41, respectively). The ratio of the residual shunt was similar in all three groups. Major complications were seen in 5 cases (4 cases with migration, and 1 case with dislocation) in group 3 and 1 case (migration) in group 1. Conclusion: Depending on the complexity of the defect and age of the patient, transcatheter closure of atrial septal defect might have certain difficulties and complications. Patients must be evaluated in detail to avoid major complications and possible problems during the procedure.

Background and objective: Numerous flood disaster events encourage mitigation efforts. One of the efforts is educationto high school and college students through a project-based learning (PjBL) model during COVID-19. The PjBL innovationcan be developed by teachers with a formulation that integrates it with learning media and higher-order thinking skills(HOTS) as the measured parameter. Methods: The research goal is to analyze high school and college students’ HOTS, learning media, and the PjBL model. Learning method employed in the research is descriptive. The HOTS instrument was developed according to Anderson'staxonomy to measure the ability of high school and college students. Results: The research results indicated that the HOTS score of the high school and college students was very low at 28.29and 46.01, respectively. The research results suggested an improvement of the HOTS by developing a learning medium toenhance students’ HOTS. In addition, the results of the study also showed that the role of teachers and lecturers was veryimportant in facilitating the use of learning media. Conclusion: Teachers and lecturers in this context must be able to facilitate the formation of loving behavior towards theenvironment. The learning media will be a content supplement for the primary, secondary, and higher education in learningflood concepts. Based on the results, the conclusion is that high school and college students’ HOTS score is in a lowcategory and all aspects of learning media can be integrated with PjBL.
