Health applications have unique characteristics compared to other applications. This application is needed to support the health of users/families with various facilities provided according to their functions and objectives. Usability measurement is carried out to evaluate the successful use of the application using various usability criteria. This study aimed to identify, analyze, and synthesize the usability evaluation of a mobile health application. The review was carried out on 65 selected papers from 799 usability papers from the Web of Science and Scopus in the 2013 to 2023 time period. The Systematic Literature Review approach used is the Preferred Reporting Item for Systematic Reviews and Meta-Analysis (PRISMA). Based on the review results, it was identified that usability measurement on mobile health applications aims to validate system design, compare usability methods, improve application performance, and evaluate usability. Meanwhile, mHealth apps mostly function for treatment and self-care/self-management. Most of the reviewed papers used the general public as respondents. The respondents or participants in these studies are diverse and can be categorized into five groups: patients, healthcare professionals, older adults, experts, and the general public. Most of the research aims to evaluate usability with the most widely used method, the System Usability Scale, which is equipped with other supporting methods.
... In order to provide a more thorough analysis of the costs associated with using the proposed tool for the intended use case, after demonstrating that it is possible to use INNBC DApp to store on-chain different types of files we may find in a scientific article, we decided to store several complete research articles [25][26][27][28][29][30][31]. Starting with the first paper on the list [25], a randomly chosen article from the "BMC Medical Informatics and Decision Making" journal, the article comprises two fundamental elements, text and figures, that were posted on the blockchain separately. ...
... We suggest that storing data as files may be an optimal solution when dealing with scientific articles to preserve the original formatting and optimize storage cost, while storing articles directly as text may be useful when dealing with simple and short text to be immediately readable on-chain. Using the same procedure, we posted the other articles [26][27][28][29][30][31] on the blockchain (results reported in Table 1, which summarizes the results of all transactions performed in the study for ease of comparison). ...

Background
A blockchain can be described as a distributed ledger database where, under a consensus mechanism, data are permanently stored in records, called blocks, linked together with cryptography. Each block contains a cryptographic hash function of the previous block, a timestamp, and transaction data, which are permanently stored in thousands of nodes and never altered. This provides a potential real-world application for generating a permanent, decentralized record of scientific data, taking advantage of blockchain features such as timestamping and immutability.
Implementation
Here, we propose INNBC DApp, a Web3 decentralized application providing a simple front-end user interface connected with a smart contract for recording scientific data on a modern, proof-of-stake (POS) blockchain such as BNB Smart Chain. Unlike previously proposed blockchain tools that only store a hash of the data on-chain, here the data are stored fully on-chain within the transaction itself as “transaction input data”, with a true decentralized storage solution. In addition to plain text, the DApp can record various types of files, such as documents, images, audio, and video, by using Base64 encoding. In this study, we describe how to use the DApp and perform real-world transactions storing different kinds of data from previously published research articles, describing the advantages and limitations of using such a technology, analyzing the cost in terms of transaction fees, and discussing possible use cases.
Results
We have been able to store several different types of data on the BNB Smart Chain: raw text, documents, images, audio, and video. Notably, we stored several complete research articles at a reasonable cost. We found a limit of 95KB for each single file upload. Considering that Base64 encoding increases file size by approximately 33%, this provides us with a theoretical limit of 126KB. We successfully overcome this limitation by splitting larger files into smaller chunks and uploading them as multi-volume archives. Additionally, we propose AES encryption to protect sensitive data. Accordingly, we show that it is possible to include enough data to be useful for storing and sharing scientific documents and images on the blockchain at a reasonable cost for the users.
Conclusion
INNBC DApp represents a real use case for blockchain technology in decentralizing biomedical data storage and sharing, providing us with features such as immutability, timestamp, and identity that can be used to ensure permanent availability of the data and to provide proof-of-existence as well as to protect authorship, a freely available decentralized science (DeSci) tool aiming to help bring mass adoption of blockchain technology among the scientific community.
... This research has several limitations at the user level which are only aimed at farmers as users on the seller's side, so further research is needed to do this usability assessment of Kiosagri to other users such as consumers and agricultural extension practitioners who assist farmers in using digital platforms. In addition, increasing the number of respondents participating in the study is also necessary because an app's poor performance or usability scores can be attributed to the lack of user participation in the app's development [64] although for the initial usability evaluation, five participants have been considered sufficient to identify usability issues [65]. Another limitation of this study is that no information yet on how the level of digital platform adoption is at the farmer level and farmer's accessibility level to the use of technology, so future research can consider these two things related to the usability of digital platforms. ...
Purpose: This study examines the usability of a digital platform called Kiosagri.com. This study needs to carry out as one of the solutions to overcome the limited accessibility of agricultural product promotion through the use of a digital platform that is expected to have usability. Therefore, this study aims to analyze the usability of digital-based agricultural product marketing platforms at the farmer level in Region V of Bogor Regency.Methods: This research employed a mixed method with an explanatory sequential design. The intended audience for the census of respondents was farmers who had utilized the Kiosagri.com platform. Data analysis was done on 32 respondents during the quantitative phase using descriptive statistics. Ten respondents were chosen purposefully for descriptive qualitative analysis during the qualitative phase.Results: According to the results, the Kiosagri platform is very user-friendly. It is achieved as a result of several beneficial aspects connected to the benefits perceived by users, such as ease of use, suitability of design, and features offered by Kiosagri.Novelty: In this study, a different way to measure the usability of digital platforms for agricultural products marketing is applied, namely by using the explanatory sequential design by conducting usability testing using descriptive statistics through the use of questionnaires and explaining the results further using descriptive qualitative through in-depth interviews which both methods are suitable for testing user experience and usability in the agricultural sector. The results of this study will be useful for the government in implementing digital marketing of agricultural products.
The proposed mobile application aims to revolutionize the fashion industry by providing users with a seamless way to discover and purchase clothing items through image recognition technology. The app allows users to either capture images of clothing items through their device's camera or upload images from their stored files. Leveraging machine learning and computer vision algorithms, the app identifies the corresponding clothing items within the images. Upon identification, the app interfaces with e-commerce platforms such as Amazon and Flipkart to search for similar items available for purchase. The development process involves extensive research, design, and implementation of features including image recognition, camera/file upload functionality, API integration with e-commerce platforms, user authentication, and additional user-friendly features. Through rigorous testing, deployment on major app stores, and continuous maintenance, the app aims to offer a seamless and engaging experience for fashion enthusiasts while adhering to user privacy and data security standards.
