기존 컴퓨터의 성능은 미세공정을 통해 기하급수적인 발전을 하였다. 하지만 성능 저하 문제로 인해 한계에 다다랐고 이를 대체하기 위해 미국 IT 주요 기업을 주축으로 양자 컴퓨터가 발전하고 있다. 양자 컴퓨터는 많은 양의 연산을 동시에 처리할 수 있어 양자 알고리즘 구현 가능성을 증가시킨다. 또한, 정수를 기반으로 한 문제에 대해 뛰어난 연산 능력을 보여 수학적 난제에 기반하고 있는 기존의 암호 체계를 위협하고 있다. 따라서 양자 알고리즘으로부터 안전하고 기존의 암호 체계를 대신할 수 있는 양자 암호 기술이 필요하다. 양자 내성 암호(PQC, Post-Quantum Cryptography)는 양자 컴퓨터의 연산 능력으로 풀기 어려운 수학 문제를 기반한 새로운 암호 체계로 주목받고 있다. 그에 따라 본 논문은 양자 알고리즘으로부터 안전한 양자 암호 기술인 양자 내성 암호(PQC, Post-Quantum Cryptography)의 연구 동향을 소개한다.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

The purpose of this study was to explore the relationship between the sex-role stereotype of the father and the child. We investigated the following: ⑴ Is there a relationship between the sex-role stereotype of the father and the child? ⑵ Is the age of the child a variable in the relationship between the sex-role stereotype of the father and the child? ⑶ Is the sex of the child a variable in the relationship between the sex-role stereotype of the father and the child? The subjects were 193 13-year-old students attending a middle school in Seoul and their fathers and 70 5-year-olds attending a kindergarten in Kwachon and their fathers. The test for the 193 middle school students and their fathers was the Likert Scale of the Bem Sex-Role Inventory which was utilized by the experimenters after a pretest. The instrument for the 5-year-olds was the 22 story-picture card Williams and Bunnett test(1975) modified by Lee, Sook(1982). The kindergarten fathers were tested with the same instrument as the middle school fathers. The data from these 2 tests were then compared using χ^2 test and percent(%). The result of this study were: ⑴ A relationship between the sex-role stereotype of the father and the child was found only between the sex-role stereotype of the middle school students and their fathers. ⑵ Age of the child was found to be a variable in the relationship between the sex-role stereotype of the father and the child. That is, a significant relationship was found between the sex-role stereotype of the middle school students and their fathers, but not between the sex-role stereotype of the preschool children and their fathers. ⑶ Sex of the child was found to be a variable in the relationship between the sex-role stereotype of the father and the child. That is, a significant relationship was found between the sex-role stereotype of the middle school boys and their fathers, but not between the sex-role stereotype of the middle school girls and their fathers.
