EDUCATION & SERVICE · 2026 · CASE STUDY
In May 2026, I issued two Korean-language ebooks: one at 75 pages and the other at 73. The first helps readers navigate food, drug, and Korean-medicine information. The second brings disability-related oral-health services and institutions into one reading path. Korea’s National Library for the Disabled issued a separate donation certificate for each title on 13 and 15 May.
The books were finished and donated. No reader study followed, so I cannot say that they improved navigation, comprehension, or access in practice.

The problem began with the shape of the page
The project goes back to volunteer work I did as a university student, converting books for blind readers. A page that can be scanned quickly by eye becomes difficult to follow in audio when its headings are unclear or its information is packed into a table. The information exists, yet the format keeps it out of reach.
I returned to that problem in 2026 through public health information. Drug labels use unfamiliar terms. Support programmes sit across several agencies. Official documents often rely on long sentences and dense layouts. Instead of trying to compress everything into one manual, I split the work into two guides and mapped the order in which a reader would need the information.
Two guides with different jobs
Finding what to check before taking a product
Easy Access to Food, Drug, and Korean Medicine Information for Information-Vulnerable Groups covers the fields readers encounter in information about medicines, health supplements, herbal preparations, and Korean medicines. It also gathers official information routes, questions to take to a health professional, and a glossary of recurring terms. The non-commercial ebook was issued on 1 May 2026 with ISBN 979-11-999127-0-0.
Following disability-related oral-health services in one place
A Guide to Oral-Health Access for People with Disabilities Through Public Data connects public material on oral-health disparities with information about specialist dental centres, Medical Aid, and available support. It does not recommend a provider or treatment. Its job is to show what services exist and where a reader should check for current details. The ebook was issued on 6 May 2026 with ISBN 979-11-999127-1-7.
Both books are educational guides based on public information available at publication. They do not replace diagnosis, prescribing, or individual medical advice.
Reading order came before decoration
Tables were kept to a minimum because row-and-column relationships can break down in linear audio. I rewrote that material as prose, kept a consistent chapter-and-section hierarchy, and added short recaps at the end of chapters. The EPUBs carry Korean language metadata and a navigable table of contents. Styling was deliberately light so readers could change type size and colours.
The structural work and technical checks focused on the EPUB editions. The companion PDFs were not verified as tagged accessible PDFs, so I do not claim the same level of screen-reader navigation for those files.
The build record for the first guide counts 18 chapter headings, 133 section headings, and 1,160 body paragraphs. Those numbers do not measure accessibility. They show the structural work involved in turning long source material into smaller, navigable units.
What the automated checks covered
For the first EPUB, an internal EPUBCheck 5.x run reported zero errors and zero warnings. An axe-core-based audit reported no violations, while leaving 65 colour-contrast items incomplete because the test environment could not judge them automatically. A technically valid file is useful evidence, but it is not a usability result.
The library certificates have a similarly narrow meaning. They confirm that the National Library for the Disabled received the donated material; they do not endorse the books’ content or certify their accessibility. I have not posted the certificates themselves because the originals include a home address, telephone number, and date of birth.
Where the evidence stops
The record supports two completed, non-commercial ebooks, two ISBNs, PDF and EPUB files, and institutional receipt of both donations. It does not support claims about readership, screen-reader usability, faster information retrieval, or changes in health behaviour.
A proper next test would put specific navigation tasks in front of readers using their own assistive-technology setups. Time to find an item, places where navigation fails, and the questions still left unanswered would be more useful than another automated score.
