Fuzzy identity-based cryptography introduces the threshold structure into identity-based cryptography, changes the receiver of a ciphertext from exact one to dynamic many, makes a cryptographic scheme more efficient and flexible. In this paper, we propose the first fuzzy identity-based signcryption scheme in lattice-based cryptography. Firstly, we give a fuzzy identity-based signcryption scheme that is indistinguishable against chosen plaintext attack under selective identity model. Then we apply Fujisaki-Okamoto method to obtain a fuzzy identity-based signcryption scheme that is indistinguishable against adaptive chosen ciphertext attack under selective identity model. Thirdly, we prove our scheme is existentially unforgeable against chosen message attack under selective identity model. As far as we know, our scheme is the first fuzzy identity-based signcryption scheme that is secure even in the quantum environment.

Identity authentication sharing technology which allows many service providers to share the result of identity authentication of an identity provider provides several important advantages including high usability achieved by avoiding repeated registration of identity information to service providers and single sign-on, cost effectiveness of service providers achieved by outsourcing identity authentication services from identity providers, and privacy protection achieved by exposing identity information only to a limited number of controlled identity providers. However, in order for the identity authentication sharing technologies to be widely deployed in global Internet scale, the trustworthiness issue among the participating identity providers, service providers, and users should be resolved in advance. This paper firstly analyzes existing trust frameworks for identity authentication sharing. And then, based on the result of analysis, this paper proposes a dynamic and open trust framework for identity authentication sharing.

Recent expansion of urban parks has been partly successful in terms of providing urban outdoor recreation space. Unfortunately we paid very little attention to the importance of providing regional identity to urban parks until recently. Thus one of the most important tasks of the contemporary landscape architects of Korea is to investigate ways to improve regional identity of urban parks. This study is aimed at evaluating how well the current urban parks have realized their own regional identity. To test the effectiveness of the concept of 'identity', the identity items were created, while a research model was developed by using such variables as in urban park identity, park satisfaction, belongingness to the region, and residential satisfaction. In order to test the model, the causations were analyzed. Meanwhile, the scales to evaluating identity were reviewed by means of the unstructures group interview, and were finally determined as 10 items; culture, uniqueness, symbolic, historic nature, homogeneity, harmony, difference, public benefit, nativeness and traditionality. Data from three new towns in the capital region-Bundang, Ilsan and Sanbon-were collected, and their central parks were referred to a questionnaire survey. The data were processed using descriptive statistics, correlation analysis, multiple regression analysis and path analysis. It was found through this survey that subjects 'sentiments regarding the sample towns' regional identity differed slightly. Residents of Bundang felt the strongest amount of regional identity, followed by those of Ilsan and Sanbon. In addition, the most important scale on regional identity is 'park satisfaction', followed by 'belongingness to the region' and 'residental satisfaction'. The path analysis was conducted to interpret the causations in a more detailed and comprehensive way than correlation analysis. As a result, it was proven that the regional identity affects 'belingingness to region' through the intermediated variable 'park satisfaction', while affecting ' residential satisfaction' through the intermediate variables 'park satisfaction' and 'beligningness to region'. In other words, although the regional identity of a park does not directly affect 'belongingness to region' or 'residental satisfaction', it has indirect effects on them through intermediate variables.

This paper aims to reveal that 'identity' plays the crucial role of explaining the relation between humans and space. Geography is preoccupied with footprints of humans which are engraved on the ground. It explores why such tokens are left over. It explains the existence of humans through footsteps of them. Men leaves traces of themselves to notify that who I was and who we were. The traces left behind by humans contain narratives of their own. Through those narratives, the very men who left the traces on the ground are to be grasped. A trace engraved by a person expresses its own identity of representing that person, so the narrative contained by one trace is the narrative of that individual. The identify which is composed of its own narrative can be largely divided into two types. The two are 'changing identity' and 'unchanging identity'. 'Changing identity' shapes the identity of oneself by difference. 'Unchanging identity' constructs the identity by identifying itself with sameness. However, as one's figure in everyday life becomes identical or different, identity also varies through processes of generation and repetition. Therefore, identity is currently changing and in progress.

The purpose of this study is to consider the relation between the deciding factors of local identity and local image improvement. To achieve this purpose, the deciding factors of local identity have been set as the following four: historical identity, cultural identity, (nature) scenery identity, and industrial identity. The writer has established a model to represent the relation between these factors and the local image improvement, namely 'Visitor Satisfaction' and 'Revisit Intentions', and framed a hypothesis for empirical verification. The study results are as follows: First, the deciding factors of local identity which this study addressed are empirically proven to have a significant effect on the visitor satisfaction and the intention to revisit in which is it likely that the greater the impact of the deciding factors, the higher the visitor satisfaction and revisit intentions would be. Second, the deciding factors of local identity, it appears that the 'historical identity' factor had the largest impact on the visitor satisfaction, and the 'cultural identity' factor had the largest impact on the revisit intentions. Therefore, of the four deciding factors, the 'historical identity' should be considered the highest priority to increase the visitor satisfaction, and the 'cultural identity' should be considered the highest priority to increase the revisit intentions. Third, based on the verification of the relation between the visitor satisfaction and revisit intentions, it can be presumed that the greater the visitor satisfaction, the higher the revisit intentions would be.

This qualitative study was designed to explore the definition of ethnic identity of the Dusuns in Brunei Darussalam from the perspective of Shamsul A.B.'s (1996) "everyday-defined" social reality. The purpose of this study was twofold. Firstly, by employing Phinney's (1996) formulation of ethnic identity, this study examined the existence of core components of ethnic identity, namely, ethnic self-identification, ethnic involvement, positive attitude towards ethnic group, and sense of belonging in the life of the Dusuns. Secondly, by utilizing Phinney's (1996) three-stage model of ethnic identity formation, this study investigated the relationship between core components and the formation process of ethnic identity. Twenty-six Dusun informants ranging in age from 8 to 80 years old were interviewed for the purpose of this study. The analysis of the interview data revealed that all core components exist and evolve in the life of the Dusuns. Different perspectives towards core components can also be identified across different age groups. Adult informants contested the relevance of ethnic involvement in view of socio-cultural transformations that occurred within the ethnic group, whereas younger Dusuns were not able to extend sense of belonging outside their family. These findings lead to the identification of family and historical contexts as influential factors that shape the ways the informants experienced the ethnic identity components. Further, the findings of this study indicate the relationship between core components and the formation process of ethnic identity. Sense of belonging and community is only evident in the experience of older informants, sufficient to help them reach the stage of achieving ethnic identity. This also shows a positive sequential relation between the stages in Phinney's ethnic identity model and the age of the informants. Interestingly, evidence on internalized sense of belonging reveals the fact that an individual could still attain ethnic identity achievement even without experiencing all components of ethnic identity. Once again, this study suggests contextual factors play a role in the stage progression of the Dusuns' ethnic identity.

Objectives : This study aimed to get the data necessary for dental hygiene students to perceive the need for establishing a professional identity as dental hygienists and developing a program which reinforce pride as a preliminary professional. Methods : The subjects were 695 dental hygiene students in Seoul, Gyeonggi and Chungcheong areas. The collected data were analyzed using the SPSS program. Results : 1. The professional identity of dental hygiene students was 3.02 points, and the satisfaction with institutes for practice was 2.96 points. 2. The higher the satisfaction with the major was, the higher the identity was. Also, the identity was high when the frequency of clinical practice was 1 (3.11 points) and when they selected their major which corresponds with his aptitude (3.20 points). 3. The satisfaction with clinical practice was high when they didn't have any experience in dental clinic before clinical practice and when the satisfaction with the major was high. 4. Regarding the correlation between the professional identity and the satisfaction with clinical practice, the higher the satisfaction with clinical practice, the higher the professional identity. 5. The effective variables regarding the professional identity were satisfaction with a major, satisfaction with clinical practice, and frequency of clinical practice. Conclusions : The professional identity of students may be established through school education involving clinical practice. The identity of students may affect the occupational satisfaction, the identity and the work efficiency of dental hygienists in the future. Thus, it is deemed necessary to have a continued collaborative relationship between a school and an institute for clinical practice so that students may establish their correct views and identity.

The current paper examines the role of the identity of entrepreneurs in the emergence and evolution of a new organizational form by empirically analyzing the evolution of eBook publishers in Korea from 1996 to 2011. Drawing on the recently developed identity-based theory of organizational form in the organizational ecology literature, we test hypotheses on the effects of focused and diffused organizational identities on organizational founding in an emergent organizational population. The results of our empirical analysis that tested three hypotheses about a positive relationship between focused identity and form emergenceand negative relationships between diffused (horizontal and vertical) identity and form emergence largely supported the argument of identity-based entrepreneurship. General implications are discussed.

Purpose : The purpose of this study was to investigate dual gender identity, masculine gender identity, feminine gender identity, undifferentiated gender identity with related to Sex, home environments, parental child-rearing attitude of warmth, parental child-rearing attitude of control, role division of parents and determine predictors for dual gender identity. Method : Study subjects were $6^{th}$ grade of primary students with 2,118. Data was collected from Oct to Nov 2003 by using structured questionnaire. Results : ${\cdot}$ Among the children, 345 had masculine gender identity, 529 had feminine gender identity, 526 had undifferentiated gender identity, and 718 had dual gender identity. ${\cdot}$ There were significant differences in the children's sex, mother's age, father's age, mother's educational level, father's educational level, existence of mother's job, father's job, social economic status, sex of siblings, mother's job satisfaction, family structure, family atmosphere, child-rearing attitude(warmth and control), role division of parents($p{\leq}0.001$) among 4 groups. ${\cdot}$ The significant predictors for dual gender identity were children's sex (OR = 0,196, P =0.001), father's age(OR = 31.053, p = 0.020), mother's educational level(OR = 43,980, p = 0.001), father's job(OR=27.465, p = 0.001), social economic status(OR=O.941, p=0.001), sex of siblings(OR = 0.329, p = 0.005), mother's job satisfaction(OR = 0.673, p =0.001), family structure(OR = 0.887, p = 0.001), family atmosphere(OR = 23.786, p = 0.001), parental Child-rearing attitude of warmth(OR = 8.043, p = 0.001) and child-rearing attitude of control(OR = 0.666, p = 0.005), role division of parents(OR = 3.009, p = 0.001). Conclusions : These findings suggest the necessity of broad understandings about factors which influence dual gender role, and construction of combinative model. Also they suggest parent education for establishment of children's dual gender identity.
