In this thesis, I tried to analyze the aspects that construct and de-construct patriarchy myth in two plays, 「Panlanquin(가마)」, and 「Men`s Impulse(남자충동)」, of a playwriter, Cho Koang Hwoa, being based on mythology of Roland Barthes. Patriarchy myths is constructed as typical situations in 「Palanquin」, and 「Men`s Impulse」. In these plays, names of important characters, for examples, Jangjeng, Dalrae, Mr. Yee and Mrs Park, are shown in common. These names are selected to stress roles of gender in patriarchy. `Palanquin` in 「Palanquin」 and `God Father` in 「Men`s Impulse」 are metaphors of patriarchy myth that is based on hierarchy of men and domination of men over women. In these plays, patriarchy is stressed as not only family system but also whole society system, figuring a family organization as a military or a gangster organization. In these two plays, the desires of incest and consanguineous killing are important dramatic actions that are chosen to reveal the originality of patriarchy and also to de-construct the originality. A mother Dalrae was attaching to her son Jangjeng in 「Panlanquin」, because she can get power only through her son in patriarchy. A brother Jangjeng has a tender passion to his sister Dalrae in 「Men`s Impulse」, and he pursues union of his family violently to continue his passion. These attachment and passion are desires of incest that are caused by patriarchy. On the other hand, Jangjeng kills his mother Dalrae in 「Panlanquin」, because he hopes to get men`s power in patriarchy. And Dalrae kills her brother Jangjeng in 「Men`s Impulse」, imitating violence that Jangjeng used. These desires of incest and consanguineous killing are desires of nature oppressed by patriarchy and also desires that are operating in patriarchy. Appearance of `others` in patriarchy is a representative aspect of de-construction. Mrs Park who followed a criterion of patriarchy obediently gets out of her house to seek her life for herself. Two men transgress against masculinity in patriarchy, as homosexualists. These plays throw questions how family and patriarchy may be, through these appearances of `others`. To make question among spectators, 「Panlanquin」and「Men`s Impulse」 resist realistic composition that is oppressed and closed. Even though these plays proceed with the lapse of time, there are many devices that give rise to critical estimation among spectators. Those are `gestus` and `cruelty`.
