Purpose: This study examined the self-esteem, self-leadership, and career identity of nursing students to identify the influence of self-esteem and self-leadership on career identity. Methods: This study was a descriptive survey of 192 students from six nursing colleges. The descriptive statistics, independent two-sample t-test, one-way ANOVA, Pearson correlation coefficient, and multiple linear regression analysis were used for statistical analyses. Results: The career identity correlated with self-esteem and self-leadership. A positive correlation was observed between self-leadership and self-esteem. The factors influencing career identity were self-esteem, satisfaction with the major, motivation (aptitude and interest), and desired career after graduation (hospital employment). The explanatory power of these variables was 42.3% in total. Conclusion: To develop a strong career identity for nursing students, it is essential to provide various educational programs that can increase self-esteem, improve awareness of the major, help students understand the roles and responsibilities of nurses, and provide opportunities to explore career options.

Purpose: This study aimed to investigate the effect of ego resilience and problem-solving ability on career identity. Methods: An online survey targeting dental technology students was conducted, and the responses of 206 students were analyzed using IBM SPSS Statistics ver. 21.0 (IBM). Descriptive statistics, independent samples t-test, one-way ANOVA (Duncan post-hoc analysis), and multiple regression analysis were performed. Results: The ego resilience-emotion control ability increased with career identity (β=0.129, p=0.007). The problem-solving and analysis ability, increased with the career identity-cognitive factor (β=0.535, p<0.001). In addition, career identity was observed to be high in male respondents (p=0.003) who were aged >23 years (p=0.002), in their 4th grade (p=0.023), had a grade of ≥4.0 (p=0.018), and hoped to get a job as a dental technician after graduation (p=0.001). Conclusion: Programs to establish the career identity of dental technology students are recommended to include contents that can improve cognitive abilities such as emotional regulation ability and problem-solving ability among those with ego resilience.

Being a mother is motherhood which means maternal role attainment and has to meet maternal identity and role confidence of caring infant. This study was designed to examine maternal identity as a motherhood and role confidence in the immediate postpartum period, and then explain the correlations of them. Data were collected for 2 months by questionnaires from 64 mothers in the hospital. The scales were to measure motherhood questionnaire which consisted of 11 items and role confidence questionnaire which consisted of 13 items. The analysis of data was done with SPSSWIN program for descriptive statistics and t-test, chi-square, ANOVA, Multiple Regression Analysis. The results were as follows: 1. Mean score of maternal identity of primipara was 55.41 and multipara was 53.81. In this outcome primipara's score was higher than multipara's. 2. Mean score of role confidence of primipara was 44.0 and multipara was 46.81. Multipara's score was higher than primipara's. 3. Correlation between maternal identity and role confidence was r=0.29(P=0.03). This was a interesting result. Because many studies reported that primipara had a lower score of maternal identity and role confidence than multipara's. But this study showed that primipara's score of maternal identity was higher than multipara's. So nurse has to support primipara's identity as a mother, taking advantage of nursing intervention from prenatal to postnatal periods. Also nurse has to offer many opportunities to experience premiparas and multiparas how to care their infants.

초기부터 웹 디자인에서는 스타일 가이드의 필요성이 논의 되었다. 하지만 실제로 그것이 무엇인지, 어떻게 적용되어야 하는지는 구체적으로 알지 못하였다. 대부분의 웹 사이트들이 그저 비슷하다는 느낌을 주는 수준에 머무르고 있다. 국내에서는 기업의 경우, Cl(corporate identity)를 웹사이트에 적용하고자 하는 노력을 계속하고 더불어 웹 스타일 가이드에 대한 개발이 진행 중에 있다. 국내 대학의 경우는 대학의 무한 경쟁시대의 도래와 함께 대학홍보와 함께 인터넷 주이용자층인 10∼20대라는 것과 대학이 바로 그들의 주된 관심사이자 직접적인 구성원들임을 감안하여 웹사이트의 필요성과 중요성이 더욱 커지고 있다. 하지만 아직 UI(university identity)를 웹사이트에 적용하고자 하는 노력은 미흡한 실정이다. 그 방법론적인 사항으로 대학웹사이트의 특성상 그리고 경제적인 이유와 함께 웹 스타일 가이드의 개발이 시급하다. 본 연구는 웹 스타일 가이드에 대한 이해와 그 필요성을 높이고, 국내 대학 웹사이트에서 그 개발 방안을 살펴보고자 한다.

Co-infection with two virus species was previously reported in some cactus plants. Here, we showed that Notocactus leninghausii f. cristatus can be co-infected with six different viruses: cactus mild mottle virus (CMMoV)-Nl, cactus virus X (CVX)-Nl, pitaya virus X (PiVX)-Nl, rattail cactus necrosis-associated virus (RCNaV)-Nl, schlumbergera virus X (SchVX)-Nl, and zygocactus virus X (ZyVX)-Nl. The coat protein sequences of these viruses were compared with those of previously reported viruses. CMMoV-Nl, CVX-Nl, PiVX-Nl, RCNaV-Nl, SchVX-Nl, and ZyVX-Nl showed the greatest nucleotide sequence homology to CMMoV-Kr (99.8% identity, GenBank accession NC_011803), CVX-Jeju (77.5% identity, GenBank accession LC12841), PiVX-P37 (98.4% identity, GenBank accession NC_024458), RCNaV (99.4% identity, GenBank accession NC_016442), SchVX-K11 (95.7% identity, GenBank accession NC_011659), and ZyVX-B1 (97.9% identity, GenBank accession NC_006059), respectively. This study is the first report of co-infection with six virus species in N. leninghausii f. cristatus in South Korea.

This study examines if the uniforms of dental hygienists influence the formation of professional identity. A self-administered survey was conducted on 534 dental hygienists in Seoul, Gyeonggi, and Incheon from March 28 to April 15, 2007. The dependent variable was professional identity. The independent variables were the organizational characteristics, uniform characteristics, and attitudes towards uniform. For the data analysis, we used t-test and hierarchical regression analysis. Using a t-test, we found the relationship between the color of the uniform and attitudes towards uniforms. The white uniform turned out to be associated with a positive perception of uniform function and uniform-image fit. The result of hierarchical regression analysis shows that the color of the uniform, perception of uniform functioning, and uniform satisfaction were statistically significant in predicting professional identity. We also tested the same model for two groups, those with and without image concern. The test results show that the significant factors were different for these two groups. This study confirms the function of uniforms in constructing professional identity and implies the need to have broader perspectives in studying uniforms.

A fuzzy identity based signature (FIBS) scheme allows a signer with identity ${\omega}$ to generate a signature which could be verified under identity ${\omega}^{\prime}$ if and only if ${\omega}$ and ${\omega}^{\prime}$ are within a certain distance of each other as judged by some metric. In this paper, we propose an efficient FIBS scheme from lattice assumption, which can resist quantum-computer attacks. Without using the Bonsai Tree technique, we utilize the lattice basis delegation technique to generate the private key, which has the advantage of keeping the lattice dimension invariant. We also prove that our proposed scheme is existentially unforgeable under an adaptive chosen message and identity attack in the random oracle model. Compared with existing scheme, our proposed scheme is much more efficient, especially in terms of communication overhead. Since our FIBS scheme possesses similar error-tolerance property, it can be well applied in post-quantum communication biometric authentication environments, where biometric identifiers such as fingerprints, voice, iris and gait are used in human identification.

An identity-based strong designated verifier signature scheme provides restricted verifiability only for a verifier designated by a signer and proper privacy for the signer. In this paper, we show that strong designated verifier signature schemes do not satisfy the self-unverifiability requirement in the sense that not only exposure of the verifier's secret key but also of the signer's secret key enables an attacker to verify signatures, which should have been the exclusive right of the verifier. We also present a generic method to construct a strong identity-based designated verifier signature scheme with self-unverifiability from identity-based key encapsulation and identity-based key sharing schemes. We prove that a scheme constructed from our method achieves unforgeability, non-transferability, and self-unverifiability if the two underlying components are secure. To show the advantage of our method, we present an example that outputs short signatures and we analyze its performance.

현재 인터넷에서 사용되고 있는 IP주소는 호스트 위치정보와 신원정보를 동시에 나타냄으로써 이동성 및 멀티호밍을 원활하게 지원하지 못하는 근본적인 문제를 지니고 있다. 이러한 문제를 해결하고자 호스트위치정보와 신원정보 분리를 주장하는 HIP(Host Identity Protocol)이 제안되었다. 그러나 IETF hip WG에서 HIP 적용을 위해 제시한 DNS(Domain Name System)가 기존의 DNS 기능의 일부 확장 아이디어만을 제시하여 그 구체성이 결여되어 있다. 본 논문에서는 HIP이 원활하게 지원될 수 있도록 동적 DNS를 구체적으로 설계하였다. 즉 기존의 DNS에 호스트 신원(Host Identity Namespace) 및 랑데뷰 서버 네임스페이스(Rendezvous Server Namespace)를 추가하고 새로운 자원 레코드(PR, Resource Records)들을 정의하였다. 이를 통해서 아이디어 차원의 HIP용 동적 DNS를 보다 구체화 하였다.
