Niimath and fslmaths: replication as a method to enhance popular neuroimaging tools.

Neuroimaging involves the acquisition of extensive 3D images and 4D time series data to gain insights into brain structure and function. The analysis of such data necessitates both spatial and temporal processing. In this context, "fslmaths" has established itself as a foundational software tool within our field, facilitating domain-specific image processing. Here, we introduce "niimath," a clone of fslmaths. While the term "clone" often carries negative connotations, we illustrate the merits of replicating widely-used tools, touching on aspects of licensing, performance optimization, and portability. For instance, our work enables the popular functions of fslmaths to be disseminated in various forms, such as a high-performance compiled R package known as "imbibe", a Windows executable, and a WebAssembly plugin compatible with JavaScript. This versatility is demonstrated through our NiiVue live demo web page. This application allows 'edge computing' where image processing can be done with a zero-footprint tool that runs on any web device without requiring private data to be shared to the cloud. Furthermore, our efforts have contributed back to FSL, which has integrated the optimizations that we've developed. This synergy has enhanced the overall transparency, utility and efficiency of tools widely relied upon in the neuroimaging community.

MOBILE-ASSISTED LANGUAGE LEARNING IN KOREAN LANGUAGE CLASSES: INDONESIAN UNDERGRADUATE STUDENTS’ EXPERIENCES AND PERCEPTIONS

The ubiquitous presence of mobile devices has benefited the implementation of foreign language learning through Mobile-Assisted Language Learning (MALL). Previous research highlights the portability aspect of mobile devices such as smartphones that can lead to spontaneous, flexible, and personalized learning activities. However, challenges remain; particularly the connectivity issues. The present study seeks to continue the discussion by investigating 79 Indonesian undergraduate students’ experiences and perceptions of MALL in their Korean language classes. The data were obtained by distributing a questionnaire to the students. The validity and reliability coefficients were also measured. Interview sessions were conducted afterward with eleven students to dig for further explanations. The results demonstrate that most students used smartphones for sending messages to peers, checking notifications, accessing materials, submitting their work, and sending messages to lecturers. Regarding the applications used, they frequently utilized smartphones for accessing Google Classroom, Zoom, and WhatsApp during their Korean classes. The results also revealed that while they perceived MALL as useful and flexible for learning Korean toward increased language skills, motivation, autonomy, and critical thinking, technical problems, and connectivity issues remain to be the main challenges. This study discusses some concerns in implementing MALL and its implications for future research.

Analisis Kualitas Software Electronic Traffic Law Enforcement di Ditlantas Polda Jawa Timur Menggunakan Teori McCall

As technology develops, humans are required to be smarter in their activities, doing works, and dealing with various existing problems. Technology is also increasingly being used as a tool to support success in various fields, including government. The government applies technology in regional governance to create a smart city. The government has developed several things that used to be conventional to become electronic-based, one of which is the ticketing system. Limitations on convention tickets as well as the large number of motorized vehicle users and traffic violations in Surabaya finally made the Surabaya Police work together with the Surabaya Transportation Agency (Dishub) to trigger the Electronic Traffic Law Enforcement system or Electronic Ticketing, commonly known as E-TLE. One of the success factors of the system is the quality of the system itself. This study aims to analyze the E-TLE software implemented in Surabaya to determine the quality of the software. The approach used to carry out the analysis is the theory of software quality according to McCall. The research method used in this research is qualitative research by collecting data using interviews, observation, and classification. The source of this research is the operator as well as designing the E-TLE software. The results show that the quality of the E-TLE software has good scores in the aspects of correctness, reliability, efficiency (data search and memory usage), integrity, usability, maintainability, flexibility, portability, reusability, and interoperability. However, there are slight deficiencies in the usability aspect (there is no integration between agencies) and lack of testability. To improve the quality of E-TLE, it is necessary to optimize page loading, add features for integration between agencies, and test to determine software grade.
