IETF suggested AAA for safe and reliable user authentication on various network and protocol caused by development in internet and increase in users. Diameter standard authentication system does not provide mutual authentication and non-repudiation. AAA authentication system using public key was suggested to supplement such Diameter authentication but application in mobile service control nodes is difficult due to overhead of communication and arithmetic. ID based AAA authentication system was suggested to overcome such weak point but it still has the weak point against collusion attack or forgery attack. In this thesis, new ID based AAA authentication system is suggested which is safe against collusion attack and forgery attack and reduces arithmetic quantity of mobile nodes with insufficient arithmetic and power performance. In this thesis, cryptological safety and arithmetical efficiency is tested to test the suggested system through comparison and assessment of current systems. Suggested system uses two random numbers to provide stability at authentication of mobile nodes. Also, in terms of power, it provides the advantage of seamless service by reducing authentication executing time by the performance of server through improving efficiency with reduced arithmetic at nodes.

This study explores the characteristics of fashion flagship stores from the consumer's viewpoint, examines the differences by brand type in the flagship store characteristics, store experience, in-store emotion, and the post-visit brand response, and compares those of the flagship store with other stores of the brand. Flagship stores of the four brand types including luxury, SPA, retail, and national brands were selected for the online survey. Data from 537 respondents who visited and selected one of those stores were analyzed. Five factors including facility/service, scale/product lines, brand identity, location, and publicity were extracted from the characteristics of flagship store. There were differences in the perceived flagship store characteristics by brand type; The luxury and retail brands were more highly perceived in facility/service comparing to the SPA brand. Store experience and brand response were also different by brand type; Perceptions of the luxury brand were also higher than of the SPA brand. Overall, consumer responses to the luxury brand were higher than to the SPA brand. Consumer responses to the flagship store were higher than to other stores of the same brand. The study discusses further implications.

Purpose: To evaluate the relationship between organizational socialization and intention to leave, and to identify factors affecting on intention to leave in operating room nurses. Methods: This study used a descriptive design. Seventy operating room nurses recruited from three hospitals under the same management style, in-service educational system, and working conditions agreed to participate in this study, and completed self-administered questionnaires of the organizational socialization and the intention to leave questionnaire. Respondents were classified by career as advanced beginner, competent practitioner, proficient practitioner and expert practitioner by Benner's stages of nursing proficiency. Data were analyzed with t-test, ANOVA with multiple comparisons, Spearman correlation, and multiple regression analysis. Results: Nurses unsatisfied with the current in-service continuous education had lower organizational socialization and higher intention to leave. In advanced beginners, job performance was lowest and organizational commitment was highest. In expert practitioners, intention to leave was highest. Organizational commitment, interpersonal relationship, identity and burnout were associated with intention to leave. Mutual trust, burnout, and interpersonal relationship were predictors of intention to leave explained 20.8% of variance. Conclusion: The career ladder program to enhance nurses' organizational socialization and intention to stay should be established and expanded for well-experienced operating room nurses.

유비쿼터스 환경에서는 프라이버시에 민감한 다양한 정보가 수집되고 이들이 통제되지 않은채 배포될 수 있기 때문에 프라이버시 보호가 필수적이다. 유비쿼터스 환경에서 프라이버시 보안을 위해 사용되는 대표적인 방법론의 하나인 익명(anonymity) 기반 기법은, 사용자가 새로운 서비스 영역에 참여할 때 가명(pseudonym)을 사용할 수 있도록 하여, 사용자의 신분을 노출시키지 않도록 하는 방법이다. 이 방법은 사용자의 신분을 보호하는데는 효과적이지만, 친구찾기 서비스, 위험지역경보, P2P통신 등 ID 기반의 서비스를 제공하기 어렵게 하는 단점이 있다. 이 논문에서는 익명기반의 프라이버스 보호 기법을 사용하는 유비쿼터스 환경에서 ID 기반의 서비스를 제공할 수 있도록 하는 시스템 구조를 제안한다.

Pharming attack is a confidence trick that the hacker catch away customers financial information on Internet banking. At first, a hacker installs malicious execution code on customers PC in secret. As a customer tries to connect a Internet banking Web site, the malicious code changes it to phishing site in Internet explorer. The hacker catch away customers financial information in process of internet banking. The hacker steals money from customer's bank account using stolen information. PKI is a widespread and strong technology for providing the security using public key techniques. The main idea of PKI is the digital certificate that is a digitally signed statement binding an user's identity information and his public key. The Internet banking service stands on the basis of PKI. However, the bank is trusted in natural, the only customer is certified in the present Internet banking. In this paper, we propose a method of cross certification in Internet banking. The customer certify a bank and the bank certify the customer in proposed method. The method can service to customer the secure Internet banking about pharming attack. We compare the proposed method with other methods.

In countries with FMD vaccination, as in Korea, typical clinical signs do not appear, and even in FMD positive cases, it is difficult to isolate the FMDV or obtain whole genome sequence. To overcome this problem, more rapid and simple NGS system is required to control FMD in Korea. FMDV (O/Boeun/ SKR/2017) RNA was extracted and sequenced using Ion Torrent's bench-top sequencer with amplicon panel with optimized bioinformatics pipelines. The whole genome sequencing of raw data generated data of 1,839,864 (mean read length 283 bp) reads comprising a total of 521,641,058 (≥Q20 475,327,721). Compared with FMDV (GenBank accession No. MG983730), the FMDV sequences in this study showed 99.83% nucleotide identity. Further study is needed to identify these differences. In this study, fast and robust methods for benchtop next generation sequencing (NGS) system was developed for analysis of Foot-and-mouth disease virus (FMDV) whole genome sequences.
