The irony is that media and instruments of communication for a human society develop flashily, but a lot of conflict and difficulry of communication are just inversely deepened. Korea has a lot of political and economical problems, tension between South Korea and North Korea, socio-economic stratum problems, generation gap, gender discrimination, labor management conflicts, and an increase of foreign immigrants. Korean linguistics and literature as humane studies of communication and liberal arts should have a sense of responsibiliry for the miscommunication and misunderstanding in Korea. Korean language education also should make great efforts to cure them. The causes of these miscommunication and misunderstanding can be diagnosed by communication study, speech science, anthropology, ethnography, speech act theory, applied linguistics, rhetoric studies, and intercultural studies. The miscommunication of Korean sociery has been affected by ideological quarrel, authoritative organizational cultures, unilateral communication, and immature culture of discussion. We should try to enhance of speech manners, artentive hearing, a culture of discussion without authoritarianism, and communiry spirit of anti-ideology. It also needs to promote the literacy of the people, sino-chinese characters education, prohibition on discrimination, and brevity of official language by the realization of the spirit of King Sejong who looked for the ideal language policy based on the spirit of independence, love for the people, and practicality.
