AI is changing how investors look at memory semiconductors. This article breaks down Chairman Choi Tae-won’s view on SK Hynix as a potential long-term holding, focusing on demand for HBM, server DRAM, and high-performance memory as AI data centers expand. It also highlights the other side: memory prices, oversupply risk, customer spending cycles, valuation, cash flow, and portfolio weighting all remain important. Not an investment recommendation—just a practical look at the key variables behind the discussion.

Manual therapy billing rules have changed. Under the new managed care benefit system, the per-session fee is standardized at 43,850 won, instead of varying by hospital. Patients generally pay a 95% copayment, and the basic limit is 2 sessions per week, up to 15 sessions per year. There are exceptions: certain medical cases, such as joint stiffness after surgery or a fracture, may be approved for up to 24 sessions based on medical judgment. The article also explains what is not covered, including therapy for fatigue recovery or posture correction.

What makes an AI agent workflow reliable? Loop Engineering focuses on building systems where agents can keep improving results through a structured cycle: planning, execution, testing, error analysis, and refinement. The article breaks down the essentials: automation, worktrees, skills, plugins/connectors, subagents, and memory. It also explains why safe loops need clear instructions, access control, cost management, quality checks, and termination conditions. A practical read for anyone thinking beyond prompts and toward repeatable AI workflows.

Learning the Claude API doesn’t have to start from a blank file. The article walks through Claude Cookbooks, Anthropic’s official GitHub collection of Jupyter Notebook examples. You’ll find practical patterns for classification, summarization, RAG, customer-service chatbots, natural-language data retrieval, and processing PDFs, charts, and images. A useful takeaway: run small examples first, manage API keys and costs carefully, then adapt prompts, inputs, error handling, and evaluation to your project.

National Pension premiums may look different from July. The standard monthly income used to calculate contributions is being adjusted: • Upper limit: 6.37M → 6.59M won • Lower limit: 400K → 410K won • Premium rate: 9.5% • Maximum monthly contribution: 626,050 won High earners above the cap may see the biggest increase, while employees generally pay half because employers cover the other half. The article also explains how higher contribution bases can affect future old-age pension amounts.
