Today, development of science-technology gives people bountiful life, but the serious environmental disruption that it makes can threaten safety of lives and bodies of people. For example, AI, BSE, SARS, GMO, and accidents related to nuclear power generation, foods, medicine etc threaten safety of lives and bodies of people. The greatest subject in modern societies with technological development is decisively to guarantee the safety connected directly with human life. Namely, the theory to guarantee safety of people from Risiko and Gefahr caused by the technological development should be advanced through law-theoretical dogma in public law. So a matter of safety which is caused by an abundance that technological development brought is investigated to systematize law-theoretical dogma in public law. In Korea, the notion of Risiko and Gefahr is not precise. Therefore the notion of Risiko and Gefahr in German, the notion of Risiko of Niklas Luhmann, Murswiek's, the notion of Risiko of Drews/Wacke/ Vogel/Matens, the notion of Risiko three steps model of R. Breuer, the criticism of Risiko three steps model of R. Breuer of U. Di Fabio, and the notion of Risiko of O. Lepsius are analyzed. The theory of national protection obligation as theoretical ground develops on the basis of “Grundrechts auf Sicherheitthe[=fundamental rights from safety]” of Professor J. Isensee. Based on the theory of national protection obligation in constitution “Übermaßverbot” applies to concrete measures to protect the freedom of the enterpriser in the science and technology- safety administration law (Atomic Energy Act, Building Act, Pharmaceutical Affairs Act, Food Sanitation Act, Genetic Technology Act, and so on) which is embodied law of the constitution, and whether people's safety is protected or not legislates optimizing measures through “Untermaßverbot”. In particular, “Untermaßverbot” as a counterproposal is presented to a legislator by the judgement standard that guarantees safety connected directly with human life.
