Teaching

As a lecturer and visiting professor in the Department of Electronics Engineering at Chungbuk National University (CBNU), I am dedicated to providing high-quality graduate-level education that bridges cutting-edge research with practical engineering skills. My teaching focuses on interactive learning, real-world problem-solving, and establishing a solid foundation in both theory and experimentation.

Artificial Intelligence Systems I

(인공지능 시스템 I) Code: 8836618

Semester: Fall
Offered: 2025
Artificial Intelligence Systems I introduces the fundamental concepts, methods, and system-level thinking needed to design and implement practical AI solutions. The course builds a solid foundation in core machine learning and modern AI workflows, emphasizing how algorithms move from theory to real-world systems. Students will study essential learning paradigms (supervised/unsupervised learning), model development (data preparation, training, validation, evaluation), and key algorithms used in classification and prediction tasks.

IoT Network Design

8836618, 2025, 2학기

Semester: Fall
Offered: 2025
This course introduces the principles and system design of the Internet of Things (IoT), focusing on how connected devices sense, communicate, and deliver intelligent services across real-world environments. Students will learn the foundations of wireless sensor networks (WSN) and IoT architectures, then progress to practical IoT technologies including device hardware (sensors/actuators), IoT operating systems, and communication models. The course also covers essential wireless protocols and long-range connectivity options such as LoRaWAN, NB-IoT, and 5G, with emphasis on selecting technologies based on performance constraints (energy, latency, coverage, and scalability).
