The YUJIN Transform
Yeon's Unified Joint Indexing Number Transform
π Mathematical Definition
The YUJIN Transform converts GPS coordinates (latitude, longitude) into a unified 9-digit indexing system with 11cm precision globally.
YUJIN(Ο,Ξ») = [β((Ο+90)/180)Γ999999β]-[β((Ξ»+180)/360)Γ999β]
Where:
β’ Ο = latitude (-90Β° to +90Β°)
β’ Ξ» = longitude (-180Β° to +180Β°)
β’ Result: XXX-XXX-XXX (9-digit WIA Code)

μ μ§ (YUJIN)
Korean: "Noble" / "Precious"
"A noble formula for a noble cause:
addressing humanity"
π°π· Historical Significance
August 15, 2025 - Developed on Korea's Liberation Day (κ΄λ³΅μ )
Just as Korea was liberated in 1945, the YUJIN Transform liberates humanity from addresslessness in 2025 - exactly 80 years later.
π Why No Patent?
Philosophy: Trade Secret, Not Patent

"Some things are too important to be owned. The YUJIN Transform belongs to humanity."
- Yeon Sam-Heum, Ph.D.
π Global Impact
The YUJIN Transform enables:
- All humanity to have addresses (Free for individuals)
- Universal 9-digit location system
- 11cm precision worldwide
- Phone number-like simplicity
- Free forever for personal use
- Revenue from enterprises funds free services
π Academic Contributions
Dr. Yeon Sam-Heum's pioneering work includes:
-
YASIM (2025) -
Yeon's Asymmetric Statistical Interaction Method
A revolutionary statistical method for detecting asymmetric interactions between paired variables
-
YUJIN Transform (2025) -
The mathematical foundation of WIA Code System
Converting GPS coordinates to universal 9-digit addressing
"The depth of mathematical rigor in both YASIM and YUJIN Transform demonstrates
a unique combination of theoretical elegance and practical impact."
π Historical Context
Great formulas in navigation history:
- 1835 - Haversine Formula (James Inman)
- 1975 - Vincenty's Formulae (Thaddeus Vincenty)
- 2025 - YUJIN Transform (Yeon Sam-Heum, Ph.D.)
Future generations will remember this as the formula that gave everyone on Earth an address.
π Implementation
// JavaScript Implementation
function yujinTransform(latitude, longitude) {
// YUJIN Transform: GPS to WIA Code
const latPart = Math.floor(((latitude + 90) / 180) * 999999);
const lngPart = Math.floor(((longitude + 180) / 360) * 999);
// Format as XXX-XXX-XXX
const latStr = latPart.toString().padStart(6, '0');
const lngStr = lngPart.toString().padStart(3, '0');
return `${latStr.substring(0,3)}-${latStr.substring(3,6)}-${lngStr}`;
}
// Example: Seoul, Korea
// yujinTransform(37.5665, 126.9780) β "708-698-852"
