Teaching 강의

Courses taught at the undergraduate and graduate levels. Databases and File Processing have run since 2008.

Databases 데이터베이스

Undergraduate

Undergraduate · 3rd year · major core

Fundamentals of database systems: data models, the ER model, and the relational model; the SQL query language and relational algebra; transactions; and normalization theory (1NF–BCNF) as the key stage of database design — with hands-on labs on a commercial DBMS.

Text Silberschatz, Korth & Sudarshan, Database System Concepts (McGraw-Hill)

Database Applications 데이터베이스응용

Undergraduate

Undergraduate · 4th year · advanced elective

The advanced sequel to Databases: transaction management and concurrency control, crash recovery, storage and RAID, indexing and B+-trees, query processing and optimization, object-relational databases, and OLAP, data warehousing and data mining.

Text Silberschatz, Korth & Sudarshan, Database System Concepts, Vol. II

File Processing 파일처리

Undergraduate

Undergraduate · 3rd year · project-based (PBL)

File storage devices, logical vs. physical files, direct access, indexing, cosequential processing and k-way merge sort, B-/B+-trees and hashing — connecting file structures to DBMSs and to modern SSD/flash storage.

Text Folk, Zoellick & Riccardi, File Structures: An Object-Oriented Approach with C++ (Addison-Wesley)

Advanced Topics in Databases 데이터베이스특론

Graduate

Graduate · Dept. of Computer Science

Graduate special topics in databases — advanced dynamic-data management including moving-object and trajectory data, stream data, and P2P / sensor-network data systems.

Advanced Mobile Data Management 모바일데이터관리특론

Graduate

Graduate · Dept. of Computer Science

Graduate course on managing dynamic data in mobile environments: wireless and mobility issues, location-based services, data broadcasting, P2P databases and DHTs, and disconnected operation — run with paper seminars and a term project.

Computer Mathematics II (Discrete Mathematics) 컴퓨터수학 2

Undergraduate

Undergraduate · 1st year · math/science foundation

Discrete mathematics: relations and their properties, closures and equivalence, partial orderings, graphs (Euler/Hamilton paths, shortest paths, planarity, coloring), trees and spanning trees, and Boolean functions and logic circuits.

Text Rosen, Discrete Mathematics and Its Applications (McGraw-Hill)

Creative Engineering Design 창의적공학설계

Undergraduate

Undergraduate · 1st year · design (ABEEK)

An introduction to engineering design through team projects — ideation methods (brainstorming, SCAMPER, the Gordon method, TRIZ) and QFD applied to hands-on creative design work.

Capstone Design 전공종합설계

Undergraduate

Undergraduate · capstone (ABEEK design)

A software-engineering capstone: requirements analysis, DB-schema and use-case modeling, hardware/software architecture, and a full team implementation project.

Information Technology Seminar I & II 정보기술세미나 1·2

Undergraduate

Undergraduate · 4th year · 1 credit each, Pass/Fail

A two-part senior seminar series introducing current IT trends and research directions to graduating students.
