Objectives The purpose of this study is to explore research directions for supporting out-of-school youth by examining domestic trends on the topic ‘out-of-school youth’ through keyword network analysis. Methods To end, we searched studies published in academic journals registered with National Research Foundation Korea from 2004 2024. Jun., selected a total 300 papers as analysis subjects, and conducted frequency centered keywords presented papers. Results First, began first article 2007,...
Food image classification is useful in diet management apps for personal health management. Various methods classifying food images a particular country have been proposed multiple studies. However, knowledge of Korean limited. The objective this study was to train model images. To the model, we collected from AI-Hub platform, public dataset. were pre-processed and augmented training. evaluated an experiment using dataset effectively classified based on transfer learning. findings revealed...
It is essential to understand research trends for researchers, decision-makers, and investors. One way analyze collect author-defined keywords in scientific papers. Unfortunately, while are beneficial researchers aiming figure out the of their fields, 45% papers Microsoft Academic Graph did not contain keywords. Additionally, six top seven AI conferences neither nor disclose This paper proposes a method generating using Galactica, pre-trained large language model published by Meta. We...
Live streaming refers to the broadcast of real-time videos, allowing people have synchronous interactions. While researchers' interest in live has increased recently, accessibility for with visual impairments is still under-examined. Further studies are necessary gain a better understanding how streamers (SVI) engage various activities on platforms. Based semi-structured interviews 14 participants, we identified SVI's motivations streaming, their unique interactions videos and platforms,...
Alternative (alt) text is essential for people with visual impairments to acquire information about image content through a screen reader. However, collecting images and creating alt requires time effort. To deal this problem, automatically that have no ensure all in web page has their text. Additionally, automatic limitations accuracy quality compared human-created despite the improvements recognition natural language process technology. We present WATAA, authoring assistant collects...
We explore a community of blind or visually impaired (BVI) people through video blogs (vlogs) on YouTube. Many researchers have used vlogs as means identifying communities bloggers (vloggers). Nevertheless, little is still known about how BVI vloggers interact in video-based social media. To fill the gap, we identified and types they produced by analyzing videos Also, found were connected with each other vlogs. our knowledge, this first attempt utilizing to understand
An international survey to explore current and future trends in Nursing Informatics (NI) was done 2015. This article explores responses questions about: what should be further develop NI as an independent discipline; existing policies standards influencing NI; perceived support towards a advice from specialists students emerging professionals.
 Nurse allied health professionals academia practice were reached with snowball sampling. Open-ended analysed thematic content analysis the mean...
In this paper, we analyzed videos to explore blind or visually impaired (BVI) people on YouTube. While researchers found how BVI interact with contents and other social media platforms (e.g., Facebook), little is known about the experience of video-based YouTube). To use as a mean identifying needs YouTube, collected specific type video called Visually Impaired People (VIP) Tag video. This has set structured questions eye condition person. Based qualitative analysis 24 VIP created by people,...
We present one part of the results an international survey exploring current and future nursing informatics (NI) research trends. The study was conducted by International Medical Informatics Association Nursing Special Interest Group (IMIA-NISIG) Student Working Group. Based on findings from this cross-sectional study, we identified NI priorities. used snowball sampling technique to reach respondents academia practice. Data were collected between August September 2015. Altogether, 373...
In the summer of 2015, International Medical Informatics Association Nursing Special Interest Group (IMIA NISIG) Student Working developed and distributed an international survey current future trends in nursing informatics. The was based on literature informatics translated into six languages. Respondents were from 31 different countries Asia, Africa, North Central America, South Europe, Australia. This paper presents results responses to question: “What should be done (at a...
Timebanking is a growing type of peer-to-peer service exchange, but hampered by the effort finding good transaction partners. We seek to reduce this using Matching Algorithm for Service Transactions (MAST). MAST matches partners in terms similarity interests and complementarity abilities needs. present an experiment involving data participants from real timebanking network, that evaluates acceptability MAST, shows such algorithm can retrieve are subjectively better than based on matching...
SaGol is an AI-powered application to improve image accessibility for people with visual impairments (PVI) users. Alternative (alt) text, a general method of web PVI users, text or phrases that describe images on website in understandable way. generates alt the user's smartphone using vision large language model called MiniGPT-4. searches similar based generated text. We evaluated length and search accuracy. This paper shows potential opportunity

Previous researchers developed validated dietary assessment methods using images of food items to improve accuracy self-reporting over traditional methods. Nevertheless, little known about usability image-assisted for adults with Objective The aims this study were (1) create record app...
Passwords are the most common user authentication methods. Password policies regulate passwords to a certain degree of complexity, which also makes it difficult for users create and remember passwords. managers improve both security usability by allowing memorize only one master password. However, authenticating password manager with has risk exposing all when is breached. We present manager, MonoPass, that leverages regenerate consistent across variety devices passes metadata through...
Despite numerous solutions offered, offline shopping experience for people with visual impairments (PVI) does not seem to improve much. A lot of PVI have only visually but also economically challenging. However, existing need additional devices or do help them economically. Therefore, the goal this research was develop a system that helps go conveniently and We conducted qualitative surveys interviews eight PVI. Based on identified challenges, we proposed opportunities easy economical...
Nursing informatics (NI) can help provide effective and safe healthcare. This study aimed to describe current research trends in NI. In the summer 2015, IMIA–NI Students Working Group created distributed an online international survey of NI trends. A total 402 responses were submitted from 44 countries. We identified a top five areas: standardized terminologies, mobile health, clinical decision support, patient safety big data research. funding was considered be difficult acquire...
