South Korea's Tourism Balance Returns to Surplus After 11 Years
- In March 2026, South Korea's tourism balance turned to a surplus of 387.5 billion won.
- After 11 consecutive years of deficits, this trend has reversed for the first time, with medical and wellness tourism filling the gap left by reduced duty-free shopping.
- The length of stay and spending per visitor also increased, so it is difficult to see this as a simple rebound.
- Targeting this market is better done by linking the broken connections between hospitals, reservations, and onsite operations rather than relying on general travel apps.
Why LLM Agents Fail in Production: Lack of Design Patterns
- Two papers summarizing agent design have been published side by side on arXiv.
- One divides 27 patterns into two axes: cognitive functions and execution topology, while GraphBit claims to have eliminated hallucination routing using a DAG and Rust engine.
- If you've experienced an agent working fine in prototype but entering an infinite loop in production, the classification chart is useful.
- However, the chart doesn't replace judgment for domain-specific failures.
