성교육
John J. Burt defined sex education as the study of the characteristics of beings: a male and female. Such characteristics make up the person's sexuality. Sexuality is an important aspect of the life of a human being and almost all people, including children, want to know about it. Sex education includes all the educational measures which - regardless of the particular method used - may center on sex. He further said that sex education stands for protection, presentation extension, improvement and development of the family based on accepted ethical ideas.
