We newly propose a multiple and unlinkable identity-based public key encryption scheme which allows the use of a various number of identity-based public keys in different groups or applications while keeping a single decryption key so that the decryption key can decrypt every ciphertexts encrypted with those public keys. Also our scheme removes the use of certificates as well as the key escrow problem so it is functional and practical. Since our public keys are unlinkable, the user's privacy can be protected from attackers who collect and trace the user information and behavior using the known public keys. Furthermore, we suggest a decryption key renewal protocol to strengthen the security of the single decryption key. Finally, we prove the security of our scheme against the adaptive chosen-ciphertext attack under the random oracle model.

Recruiting and maintaining capable physical therapists in hospitals is crucial to provide patients with better quality's physical therapy and to achieve hospital business objectives. This study is to provide basic data for effective personnel management of physical therapists in the hospital. For this, this study was conducted to confirm the relationship between turnover intention and job characteristics(task importance, job autonomy, job feedback, task identity, skill diversity), and to find out factors affecting the turnover intention of hospital physical therapists in Korea. The sample used in this study consisted of 173 physical therapists who were working in hospitals located in Seoul from June 18 to 29. The data for analysis were collected by questionnaire survey. The dependent variable of this study was turnover intention and the independent variables were job characteristics(task importance, job autonomy, job feedback, task identity, skill diversity), demographic characteristics of respondents(sex, age, education level, marital status, working hospital, working career). The major statistical methods used for the analysis were factor analysis, t-test, ANOVA, correlation, and hierarchical multiple regression analysis. Turnover intention according to demographic characteristics of respondents was significantly high in the graduate school above group. As the result of hierarchical multiple regression analysis of turnover intention, R2 of job characteristics was much more powerful than demographic characteristics. The factors had significant negative effect on turnover intention were job autonomy, task identity, and skill diversity. And in demographic characteristics factors, there were not significant factors on turnover intention. In considering above findings, for decreasing turnover intention of physical therapists, hospitals need to develop strategies for enhancing job satisfaction by improving job autonomy, task identity, and skill diversity from the adequate job environment.

Purpose: This study is descriptive correlation study to identify the factors on career identity of nursing students. Methods: From october $15^{th}$ to november 5th, 2016, data was collected through convenience sampling of 177 college students based on C province, two G provinces. Statistical analysis of t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis was performed through the SPSS WIN 21.0. Results: career identity is significantly positively related with self-esteem, and negatively related with depression (r=-.529, p<.001). Nursing students' verbal abuse is significantly positively related with sexual violence (r=.615, p<.001), depression (r=.540, p<.001) and sexual violence and depression are significantly negatively related (r=.299, p<.001) and depression and self-esteem are significantly negatively related (r=-.390, p<.001).Variables that affect career identity include depression, self-esteem, grade, and whether they belong to a specific hospital. The total explanation of career identity was 52.2%. Conclusions: These results suggest that educational intervention is needed to improve the career identity among nursing students. It is necessary to encourage students to proactively seek abuse preventive measures.

This study was conducted as descriptive research to examine the relations among beauty business workers' professional identity, emotional labor and depression, to analyze factors that influence their depression, and to provide basic information necessary to develop interventions for beauty business workers' depression. The subjects of this study were 158 beauty business workers sampled from 25 beauty shops in Seoul. Data were collected using a structured questionnaire during the period from April 12 to May 13, 2011. From the collected data were obtained real numbers, percentages, and the means and standard deviations of professional identity, emotional labor and depression using the SPSS 16.0 Program. In addition, multiple regression analysis was performed to determine the correlations among the variables and to identify factors influencing the beauty business workers' depression. In the results of multiple regression analysis on factors that influence the subjects' depression, factors found to explain their depression were autonomy among the sub factors of professional identity, and the diversity of emotional expressions and surface acting among the sub factors of emotional labor, and these factors explained 23.6% of their depression. The subjects' professional identity was in a positive correlation with the frequency of emotional expressions and deep acting among the sub factors of emotional labor, and in a negative correlation with surface acting and depression. The Frequency of emotional expression and the diversity of emotional expressions which the sub factors of emotional labor were in a negative correlation with depression and in a positive correlation with surface acting and depression. In order to relieve beauty business workers from their depression based on these results, there should be education or programs for establishing beauty business workers' professional identity and program for increasing of emotional expressions and decreasing of surface acting.

The problem of compressed sensing (CS) based multiple access is studied under the assumption of random data traffic. In many multiple access systems, i.e., wireless sensor networks (WSNs), data arrival is random due to the bursty data traffic for every transmitter. Following the recently developed CS methodology, the technique of compressing the transmitter identities into data transmissions is proposed, such that it is unnecessary for a transmitter to inform the base station its identity and its request to transmit. The proposed compressed multiple access scheme identifies transmitters and recovers data symbols jointly. Numerical simulations demonstrate that, compared with traditional multiple access approaches like carrier sense multiple access (CSMA), the proposed CS based scheme achieves better expectation and variance of packet delays when the traffic load is not too small.

The sutdy is to investigate the variables that influenced on territoriality$.$privacy and to find the relation between territoriality$.$privacy and self-identity. Data were collected from 342 homemakers in Pusan. Data were analysed by SPSS programs. To test hypotheses frequency, correlation and Multiple Regression (Path Analysis) were applied. The results were as follows: 1. The significant variales that influenced on territoriality were space occupancy level, SES and neighborhood relationship. 2. The significant variables that influenced on privacy were space occupancy level, SES and neighborhood relationship. 3. The significant variables that influenced on self-identity were territoriality, privacy, neighborhood relationship, housing ownership, space occupancy level and SES.

The purpose of present study was to investigate the effect of sex and sex role identity on marital satisfaction. The short-from Bem Sex Role Inventory(BSRI) and Marital satisfaction Scale (MSS) were administered to the married men (n=90) and women (n=130) in Pohaing City. The data were analysed by two-way ANOVA and the Scheff method of multiple comparison. Major findings were as follows: 1. Marital satisfaction was significantly related to sex role identity rather than to sex: The androgynous group reported the highest marital satisfaction scores, whereas the undifferentiated group did the lowest scores. 2. There was no significant sex difference in marital satisfaction socres among the masculine, androgynous, and undifferentiated groups except the feminine one. Only in the feminie group, males who had high feminity scores reported high marital satisfaction scores, whereas females who had high femininity scores reported low marital satisfaction scores.

Digital Ecosystem is a new word for dynamic IT business environments. Digital Ecosystem can consist of various enterprise federations such as competing, collaborating and stable or unstable ones. They make it difficult to implement identity management for the environment. Existing solutions are either too restricting and inflexible to support the dynamic nature of ecosystems since they are too complex and difficult to adopt. This paper is to propose an distributed identity management model for automated processing of identity information between ecosystems. It is featured with being practical, clear and easy to deploy. And it is based on the new OASIS SAML3.0 standard to provide interoperability between existing identity technologies. This paper presents the basic and extended identity model for single service and multiple services. The model presented in this paper can be applied to enterprise context easily.

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.
