This research aims to provide a comprehensive analysis of the User Experience (UX) components within the KAI Access platform framework, with a particular focus on the need to evaluate the platform's UX. This evaluation is very important because of the emergence of user complaints and usability problems in the KAI Access application rating on the Appstore and Playstore which can affect user satisfaction and overall user engagement. This study leverages insights from previous research in UX analysis, particularly in transportation applications, it identifies key areas for improvement. It implements best practices to ensure a smooth and intuitive user experience. Leveraging frameworks and theories from the field of UX design, the methodological approach revolves around conducting UEQ surveys to comprehensively understand user behavior and interactions. Through systematic evaluation, this research assesses the UX dynamics of the KAI Access system, by carefully examining the strengths, weaknesses, and areas that require improvement to increase user satisfaction and system usability. This research succeeded in showing that the KAI Access platform has good performance in terms of efficiency and reliability. However, from the evaluation there are deficiencies in various areas such as user interface design and interactive responsiveness which are shown in the discussion results indicating the potential for increasing user satisfaction and system usability through pragmatic improvements. Additionally, this paves the way for future research to explore the impact of these improvements on user satisfaction and consider the integration of new technologies for a richer user experience.

Introduction: There is increasing interest in innovation development and management in the Philippines, especially in the last decade. In the advocacy for universal hearing health, the HeLe, "Hearing for Life'' Research Program was implemented. HeLe developed novel telehealth technologies and field tested a proof-of-concept service delivery model to improve provision of newborn hearing screening and intervention services in the Philippines., Objective: As the HeLe research period concludes, this appraisal was organized to document and assess the health information technology systems of the HeLe., Methods: The evaluation follows the elements of the Centers for Disease Control and Prevention (CDC) guidelines for evaluation of public health surveillance systems. It centers on the status of the eHealth-based components of the HeLe NHS interventions: HeLe NHS module in the Community Health Information Tracking System (CHITS) electronic medical records system, the Tele-Audiology module in National Telehealth System (NTS), and the HeLe NHS registry. The evaluation is based on interviews of key HeLe research staff and documentation review., Results: The HeLe system has a stable, SQL-Server-based architecture. It is a secure, web-based system with clean separation of back-end database and front-end Web, using Secure Socket Layer (SSL) technology. Standardization of data via mapping ensures reliable, comparable measures. HeLe demonstrates that NHS data collected by the HeLe NHS device can be sent to, stored in, and extracted from the CHITS electronic medical record system and exchanged across platforms. Where actual patient and NHS data were available, this HeLe system is validated to be efficacious to capture and seamlessly exchange data across various eHealth platforms. These eHealth technologies are described to be at Technology Readiness Level 5, "technologies are validated in a relevant environment". The HeLe program, however, needs to address completeness in documentation as a standard practice, if only to ensure better management of risks introduced by novel eHealth systems in patient care. The CDC public health surveillance checklist used for this assessment is useful in identifying gaps in research management for the HeLe inventors. It is recommended to be incorporated to be standard and implemented early in the next iteration of the HeLe research., Conclusions: Overall, the HeLe technologies, in this initial stage of research, have achieved the purpose for which they were developed. As a novel technology-based NHS system, HeLe is a potentially powerful tool to assist in monitoring newborn hearing disease caseloads by community-based primary care clinics, NHS facilities, and hospitals that provide definitive medical services. As other health systems strengthening reforms take root in the Philippines, secure exchange of data electronically across the country would depend on sound technologies, including those used in hearing health. This paper can be instructive to the emerging research community in the eHealth and biomedical development space especially in resource-challenged settings. Likewise, lessons can reinforce institutional support from research agencies, clinicians, and state/ county or subnational health departments for policy and resource mobilization to better manage those identified with congenital hearing loss., Competing Interests: The study on which this report was based was undertaken with the financial and administrative support of the Commission on Higher Education, Philippines – California Advance Research Institutes, and the National Institutes of Health, University of the Philippines Manila. These, however, did not have any influence on the content of this paper. Authors have no relationships with manufacturers of medical devices., (© 2023 Acta Medica Philippina.)

Dissolved organic carbon (DOC) is a sum parameter that is frequently used in water analytics. Highly resolved and accurate DOC data are necessary, for instance, for water quality monitoring and for the evaluation of the efficiency of treatment processes. The conventional DOC determination methods consist of on-site sampling and subsequent analysis in a stationary device in a laboratory. However, especially in regions where no or only poorly equipped laboratories are available, this method bears the risk of getting erroneous results. For this reason, the objective of the present study was to set up a reliable and portable DOC analyzer for on-site analysis. The presented DOC system is equipped with an electrolysis-based decomposition cell with boron-doped diamond electrodes (BDD) that oxidizes the organic compounds to carbon dioxide. Within this study, the influence of different electrode materials and the composition of the applied electrolytes on the DOC decomposition in an undivided electrolytic cell were systematically investigated. Furthermore, some technical aspects of the portable prototype are discussed. After a detailed validation, the prototype was used in an ongoing monitoring program in Northern India. The limit of detection is 0.1 mg L -1 C with a relative standard deviation of 2.3% in a linear range up to 1000 mg L C -1 . The key features of the portable DOC analyzer are: No need for ultra-pure gases, catalysts or burning technology, an analyzing time per sample below 5 min, and a reliable on-site DOC determination.
