멀티캐스트는 송신자가 많은 수신자들에게 동시에 데이터를 전송하므로 송신자의 자원을 절약하고 네트워크의 점유율을 낮춤으로 효율성을 제공하는 통신 기술이나 여러 수신자들이 같은 그룹 주소를 사용하므로 공격을 받을 위험이 크다. 따라서 멀티캐스트 스트림에 대한 인증 및 서명은 중요한 문제이다. 본 논문에서는 패킷을 전송한 송신자의 신원을 확인하고 데이터가 변조되지 않았음을 확인하는 소스 인증 방법으로 다중 체인 인증기범을 제안하였다. 제안한 기법은 부인 방지를 제공하고 여러 패킷에 대한 전자서명으로 인증함으로써 오버헤드론 줄이며 지연없이 이루어지므로 실시간 멀티미디어 서비스에 사용할 수 있다. Multicast communication is simultaneous transmission of data to multiple receivers and saves considerably sender resources and network bandwidth. It has high risk to attack using group address and inherent complexity of routing packets to a large group of receivers. It is therefore critical to provide source authentication, allowing a receiver to ensure that received data is authentic. In this paper, we propose the multiple chain authentication scheme for secure and efficient multicast stream. To evaluate the performance of our scheme, we compare our technique with two other previously proposed schemes using simulation results. Our scheme provides non-repudiation of origin, low overhead by amortizing the signature operation over multiple packets, and high packet loss resistance.

Objective: To investigate the association of genetic background between MTHFR A1298C genotype and male infertility. Materials and Methods: We compared 377 infertile males with 396 healthy fertile males with one or more offspring. Infertile males were classified into four subtypes (281 azoospermia, 26 oligoasthenoteratozoospermia (OAT), 59 severe OAT and 11 remnants) by World Health Organization (WHO). Pyrosequencing analysis for MTHFR (methylenetetrahydrofolatereductase) A1298C variation was performed on polymerase chain reaction (PCR) product of study group. To validate pyrosequencing data of A1298C variation for randomly selected 50 samples, we compared the pyrosequencing result with the PCR-RFLP (Restriction Fragment Length Polymorphism) result of MTHFR A1298C genotype. Results: We studied MTHFR A1298C variation by pyrosequencing. A1298C variation data (1298 AC; p=0.2166 and 1298 CC; p=0.5056) of MTHFR gene was no significant difference in between fertile and infertile males. Conclusion: The genetic analysis in MTHFR gene didn't appear genetic difference in Korean fertile and infertile males. We require further study for MTHFR gene in infertile males.

In the case of a fire in the city center where population and buildings are dense, the risk of a social disaster increases. In order to find concrete solutions to prepare for this, it is necessary to analyze the spatial scope. Accordingly, using GIS for Jung-gu, Seoul, which has a high population density, the population vulnerable to disasters, the ratio of old buildings, and the density of fires were derived, and the areas excluded from the fire service area through network analysis were analyzed for each administrative dong to determine the final fire-vulnerable area. Therefore, based on the analysis results, a plan for readjustment of areas that can prepare for disasters according to social, physical, and regional characteristics was studied.
근대 초기 영국 희곡의 국외 연구동향 : 여성과 극장을 중심으로
정유미 ( Jung Youmi ) 영미문학연구회 2021 안과 밖 Vol.- No.50
This paper surveys recent studies in early modern English drama with a focus on women’s active involvement in the seventeenth-century dramatic production and theater culture. Questioning the powerful cultural paradigm of “the English all-male stage,” critics of the late 1990s called for a need to revise the literary and theater history that had largely excluded women. While feminist critics have brought to our attention how early modern women’s literary activities were neglected in the literary criticism, their revisionist projects of discovering women writers comparable to Shakespeare or Jonson fail to account for the women’s more extensive contribution to early modern drama and theater culture. In the recent scholarship, the notions of women’s dramatic production and theatricality have been considerably expanded to include non-commercial dramatic genres and women’s diverse roles and their work in and out of the theater. Pointing out how women thrived in some dramatic genres such as translation, closet drama, and household drama, critics have emphasized the interconnectedness between women’s “private” drama and a variety of theatrical traditions and dramatic forms in commercial, public theater. Early modern women’s theatricality has also been broadly expanded to reexamine the significance of women’s court and street performances, French and Italian actresses in London streets, and women’s off-stage or on-page contributions to early modern dramatic literature and performance. Such interdisciplinary efforts have uncovered a diverse range of female theatrical activities beyond the single-sex playhouse stages, which has changed our understanding of early modern drama including the plays of Shakespeare and other canonical authors.

Purpose: The purpose of this study was to develop a disaster ethics education program for Korean nurses to improve their ethical competency in disaster response. Methods: This study adopted Rapid Prototyping Model with three phases. For the information gathering phase, a literature review and a focus group interview were carried out to identify education contents and nurses’ demand for disaster ethics education. During the 1st iterative loop, a prototype was developed, and a validity test was done. Next, the authors implemented the prototype for nurses as a pilot test, revised it based on their feedback, and finalized it. Results: The disaster ethics education program consisted of 5 sessions: Introduction Session, three Disaster Nursing Ethics Sessions, and Debriefing Session. Each Disaster Nursing Ethics Session included a pre-lecture, a case analysis and discussion, and a post-lecture. S-CVI of the prototype was .94 and the participants' satisfaction score in the pilot test was 4.68 out of 5.00. Conclusion: This study developed a disaster ethics education program for nurses, using Rapid Prototyping Model, for the first time in Korea. This program will contribute to enhancing the ability of nurses to respond to disasters by improving their ability to make ethical decisions.

Purpose: The purpose of this study was to identify the effects of Nunchi, clinical practicum stress, and communication skills on clinical practicum adaption among Korea Armed Forces Nursing Academy (KAFNA) cadets. Methods: This study was a descriptive study and 158 cadets in 3rd and 4th year were recruited to respond to a self-reporting questionnaire in July, 2021. Statistical methods for data analysis included independent t-test, one-way ANOVA with Bonferroni post-hoc, and multiple regression. Results: The mean scores of the cadets’ Nunchi, clinical practicum stress, communication skills, and clinical practicum adaption were 4.11±0.47, 2.76±0.59, 3.95±0.44, and 3.48±0.53, respectively. The clinical practicum adaption had positive correlations with Nunchi (r=.26, p=.001) and, communication skills (r=.48, p<.001), and a negative relation with clinical practicum stress (r=-.34, p<.001). A statistically significant correlation was also found between Nunchi and communication skills (r=.56, p<.001). The multiple regression analysis presented that the communication skills (ß=.31, p=.001) had the greatest influence on the clinical practicum adaption and a major satisfaction (ß=.31, p=.039). The model explained 44.0% of the cadets’ clinical practicum adaption(F=11.28, p<.001). Conclusion: In order to promote cadets' clinical practicum adaption, education and training to further enhance their communication skills are continuously needed.
