The pursuit of independent self-development in adolescence and the development of self-identity are related to their adaptation in social life. In Korea, too, college is the place where graduates from high school go to advance in society. The purpose of study is to investigate the relationship between self - identity and college life in university students. First, self - identity has a positive effect on academic adjustment. Specifically, goal orientation has a positive effect on academic adjustment. Second, self - identity has a positive effect on emotional adjustment. In detail, self-acceptance, future confidence, and goal orientation were found to affect emotional adaptation. Finally, self - identity did not affect university satisfaction.

With delegating proxy to process data before outsourcing, data owners in restricted access could enjoy flexible and powerful cloud storage service for productivity, but still confront with data integrity breach. Identity-based data auditing as a critical technology, could address this security concern efficiently and eliminate complicated owners' public key certificates management issue. Recently, Yu et al. proposed an Identity-Based Public Auditing for Dynamic Outsourced Data with Proxy Processing (https://doi.org/10.3837/tiis.2017.10.019). It aims to offer identity-based, privacy-preserving and batch auditing for multiple owners' data on different clouds, while allowing proxy processing. In this article, we first demonstrate this scheme is insecure in the sense that malicious cloud could pass integrity auditing without original data. Additionally, clouds and owners are able to recover proxy's private key and thus impersonate it to forge tags for any data. Secondly, we propose an improved scheme with provable security in the random oracle model, to achieve desirable secure identity based privacy-preserving batch public auditing with proxy processing. Thirdly, based on theoretical analysis and performance simulation, our scheme shows better efficiency over existing identity-based auditing scheme with proxy processing on single owner and single cloud effort, which will benefit secure big data storage if extrapolating in real application.

It is known that being hierarchical is a necessary and sufficient condition for a poset to admit MacWilliams identity. In this paper, we completely characterize the structures of posets which have an association scheme structure whose relations are indexed by the poset distance between the points in the space. We also derive an explicit formula for the eigenmatrices of association schemes induced by such posets. By using the result of Delsarte which generalizes the MacWilliams identity for linear codes, we give a new proof of the MacWilliams identity for hierarchical linear poset codes.

Individuation and ego identity formation was studied in 297 university students in North Cholla Province. They completed the Korean Late Adolescent Individuation Questionnaire, and the revised version of the Objective Measure of Ego Identity Status. One-way ANOVA revealed differences in identity status as a function of individuation categories except in moratorium status. Individuated(??) students yielded the highest identity achievement scores and the lowest diffusion scores. Ambiguous students yielded the highest diffusion scores. Less individuated(??) students had the highest foreclosure scores while pseudo-autonomous students had the lowest foreclosure scores.

This study determines the factors that contribute to the sense of self-identity for children from multicultural and rural families and provides a systematic understanding of individual self-identity. It also provides implications on how parents, teachers, and professionals can approach their role when instructing and rearing children of different sociocultural backgrounds. The subjects consist of the 310 children from multicultural families (Korean fathers and immigrant mothers) residing in South Korea and 280 children from rural families with similar conditions to those in multicultural families in North Jeolla Province South Korea. The sense of self-identity and maternal parenting behavior were perceived differently by children of multicultural and rural families, whose sense of self-identity was affected by school satisfaction and maternal parenting behavior.

Purpose: The aim of the research was to define the effects of body image, career identity, and family health on depression in college students. Methods: This descriptive research was conducted from the 1st to the 16th of July, 2018. The data was collected through convenience sampling of 222 college students. To draw conclusions from the data, we used statistical analysis of Pearson's correlation coefficients and stepwise multiple regression using SPSS/WIN 21.0. Results: Depression showed negative correlations with body image, career identity and family health. Multiple regression revealed that the factors significantly influencing depression were body image, career identity, and gender. The total explanation of depression by these variables was 29.9%. Conclusion: These findings indicate that intervention strategies to prevent and manage depression in college students should include programs to help them develop positive body image and career identity, considering gender differences.

Motivation of human individuals to perform on intellectual tasks can be hampered by identity threat from intellectual machines. A laboratory experiment examined whether individuals' performance loss on intellectual tasks appears under human identity threat. Additionally, by affirming alternative attributes of human identity, researchers checked whether group-affirmation alleviate the performance loss on intellectual tasks. This research predicted that under high social identity threat, individuals' performance loss on the intellectual tasks would be moderated by valuing alternative attributes of human identity. Experiment shows that when social identity threat is increased, human individuals affirmed alternative human attributes show higher performance on intellectual tasks than individuals non-affirmed. This effect of human-group level affirmation on performance loss did not appear in the condition of low social identity threat. Theoretical and practical implications were discussed.

Purpose: This study was to examine the differences in the degree of premenstrual syndrome, dysmenorrhea, and stress according to the gender role identity of female university students. Methods: Data were collected by self-reported questionnaires from 308 female university students. Data analysis was done with SPSS 10.1 for descriptive statistics, ANOVA, and Duncan's multiple-range test. Results: The most prevalent type of premenstrual syndrome was androgenic(33.8%), followed by undifferentiated(25.0%). There was a significant difference in dysmenorrhea according to residence. In addition, there were significant differences in premenstrual syndrome according to age, and in stress according to age and economic status. Also, there was no significant difference according to dysmenorrhea and there were significant differences in premenstrual syndrome and dysmenorrhea according to gender role identity. Premenstrual syndrome and stress were the most prevalence in female type, but the lowest severe in masculine type. Conclusion: The study variables can be influencing factors in the gender role identity of female university students. Also, the findings can provide the basis for the development of nursing interventions to establish the gender role identity of female university students.

Each cloud service has numerous owners and tenants, so it is necessary to construct a privacy preserving identity management and access control mechanism for cloud computing. On one hand, cloud service providers (CSP) depend on tenant's identity information to enforce appropriate access control so that cloud resources are only accessed by the authorized tenants who are willing to pay. On the other hand, tenants wish to protect their personalized service access patterns, identity privacy information and accessing newfangled cloud services by on-demand ways within the scope of their permissions. There are many identity authentication and access control schemes to address these challenges to some degree, however, there are still some limitations. In this paper, we propose a new comprehensive approach, called Privacy pReserving Identity and Access Management scheme, referred to as PRIAM, which is able to satisfy all the desirable security requirements in cloud computing. The main contributions of the proposed PRIAM scheme are threefold. First, it leverages blind signature and hash chain to protect tenant's identity privacy and implement secure mutual authentication. Second, it employs the service-level agreements to provide flexible and on-demand access control for both tenants and cloud services. Third, it makes use of the BAN logic to formally verify the correctness of the proposed protocols. As a result, our proposed PRIAM scheme is suitable to cloud computing thanks to its simplicity, correctness, low overhead, and efficiency.

The purposes of this study were to examine the influence of the self-identity, parenting style, peer attachment, and relationship with teacher on career identity, and to verify if self- identity shows the moderating effect in the relationship among the parenting style, peer attachment, relationship with teacher, and career identity of middle school students. The data of 3rd-year middle school students, from the 1st grade panel of 'Korea Children And Youth Panel Survey(KCYPS)' by National Youth Policy Institute, was used as the analysis data. The program which was used for the analysis was SPSS ver 22.0 for descriptive, Cronbach's α, and multiple regression analysis. The results of this study are as follows. First, it was revealed that the most influential variable for career identity was self identity, followed by peer attachment, while relationship with teacher is least influential. Parenting style did not have a direct effect on career identity. Second, it was revealed that self-identity had a moderating effect when the interaction between parenting style and the self-identity, and the interaction between relationship with teacher and the self-identity were injected. Therefore, if the education related to the self-identity is conducted continuously in the home economics subject, the conflict and anxiety on the career problem of middle school students will be reduced and the career identity will be developed more effectively.
