The YUJIN Transform

Yeon's Unified Joint Indexing Number Transform

📐 Mathematical Definition

The YUJIN Transform converts GPS coordinates (latitude, longitude) into a unified 9-digit indexing system with 11cm precision globally.

YUJIN(φ,λ) = [⌊((φ+90)/180)×999999⌋]-[⌊((λ+180)/360)×999⌋]

Where:
• φ = latitude (-90° to +90°)
• λ = longitude (-180° to +180°)
• Result: XXX-XXX-XXX (9-digit WIA Pin Code)

🇰🇷 Historical Significance

August 15, 2025 - Developed on Korea's Liberation Day (광복절)

Just as Korea was liberated in 1945, the YUJIN Transform liberates humanity from addresslessness in 2025 - exactly 80 years later.

🎓 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 Pin 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."

📚 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.

🔗 Implementation

// JavaScript Implementation function yujinTransform(latitude, longitude) { // YUJIN Transform: GPS to WIA Pin 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) → "708-698-852"
