『Learn and Use Business Korean 1』 was developed to meet the objectives of Sejong Institute's Business Korean curriculum, enabling learners to acquire the business knowledge necessary for business situations based on basic Korean communication skills and improve their job skills.

To ensure that students acquire practical and essential business knowledge, we conducted a needs survey targeting Korean language teachers at overseas Sejong Institutes, prospective employees seeking employment at Korean companies, employees and middle managers at Korean companies, and company managers. The learning content was selected based on the results of the survey.
In particular, we have taken into account the needs of Korean language learners for professional purposes and the opinions of employees of Korean companies abroad, and have sequentially arranged the contents that they responded to as important in their work situations.

It is composed of essential topics, vocabulary, and expressions commonly encountered in the workplace so that learners can use them effectively in business situations.
It includes a variety of practical assignment activities to improve harmonious communication skills in speaking, listening, reading, and writing, while fostering reading and writing skills based on listening and speaking.
Considering the connection with 『Sejong Korean』, vocabulary and grammar were selected so that this textbook can be used after studying 『Sejong Korean 1, 2』.
