This study is to analyze the symbolic images appeared in modern fashion design adopted dualistic meanings in uniforms. Uniforms signify order, conformity and discipline in public life. The dualistic meanings in uniforms appeared modern times are as follows: public authority vs individual non-authority, heterosexual identity vs homosexual identity, time-space uniformity vs mixed diversity. The symbolic images appeared in modern fashion design adopted dualistic meanings in uniforms such as military uniforms, school uniforms, nurses' uniforms, sports uniforms and etc. are erotic image, hybrid image, and kitsch image.

Worldwide inter-operability for microwave access (WiMAX) is a promising technology that provides high data throughput with low delays for various user types and modes of operation. While much research had been conducted on physical and MAC layers, little attention has been paid to a comprehensive and efficient security solution for WiMAX. We propose a hybrid security solution combining identity-based cryptography (IBC) and certificate based approaches. We provide detailed message exchange steps in order to achieve a complete security that addresses the various kind of threats identified in previous research. While attaining this goal, efficient fusion of both techniques resulted in a 53% bandwidth improvement compared to the standard's approach, PKMv2. Also, in this hybrid approach, we have clarified the key revocation procedures and key lifetimes. Consequently, to the best of knowledge our approach is the first work that unites the advantages of both techniques for improved security while maintaining the low overhead forWiMAX.

Using some interesting convolution, we find kernels recovering the given function f. By a slight change of this convolution, we obtain an identity filter related to the Fourier series in the discrete time domain. We also introduce some techniques to decompose an impulse into several dilated pieces in the discrete domain. The detail examples deal with specific constructions of those decompositions. Also we obtain localized moving averages from a decomposition of an impulse to make hybrid Bollinger bands, that might give various strategies for stock traders.

This study is to analyze the dual language and hybrid identity of the students of Daegu Chinese Middle.High School. Such a phenomenon is being produced and changed at the site or zone of meeting different or conflict factors such as Chinese and Korean. The Chinese Korean students had learned Korean from their mother and her relative at a young age, and their dual and complex language habit was produced due to the learning of Chinese from father and his relative. A large number of the students were educated at a Korean kindergarten, but they were formally learned Chinese and China's society and culture at a Korean Chinese school after primary school. The Chinese Korean students talk with parents, brother and sister, teacher, friend and neighbor at home, school and local by Chinese and/or Korean. They use a dual language of Chinese and Korean based on various situations, but they do not particularly distinguished both language in cognition. The students have a hybrid identity of simultaneously recognizing Chinese and Korean. But some of them think Chinese or Korean. It is necessary for the results of this study to be objectified from the following research on the students of Chinese Middle･High School in Seoul, Incheon and Busan.

Social enterprises have been concerned with the social problems and their market survival, simultaneously. They show diverse types of organizational identities in order to pursue such hybrid goals. This study examines how the social enterprises shape their identities. In particular, it focuses on regional and industry environments that influence the types of the organizational identities of the social enterprises. This study categorizes 219 social enterprises, founded in the environmental sector, into social oriented single identity, business oriented single identity, and mixed identity enterprises using the 2014 and 2015 Social Enterprise Directory published by Korea Social Enterprise Promotion Agency. Findings are as follows: First, there are more social enterprises with a single identity in the metropolitan environment, compared to ones in the non-metropolitan environment, and social enterprises with a mixed identity are more likely to be established in the non-metropolitan environment than ones in the metropolitan environment. Second, there are more social enterprises with a social oriented single identity in the emerging industry environment than ones in the mature industry environment. Also, more social enterprises with a business oriented single identity are formed in the mature industry environment than ones in the emerging industry environment.

Through the biographical approach, the current research purports to reconstruct the Changeprocess of values and identities on the lives of the first-generation Korean-German females in Germany from the transnational perspective. Ten interviews were conducted, using Schutze's autobiographicalnarrative interview. Interview data were analyzed through the application of Schutze's autobiographical-narrative interview and Mayring's qualitative content analysis. Findings showed that on the onset of emigration, their values centered around hybrid collectivism. Their life in the process of emigration was characteristic of a shift to hybrid individualism. Furthermore, the life at beginning of emigration was found to be characterized by a singular regional identity. The process of emigration was shown to mark the conversion into dual identity, dual regional and dual national. Some theoretical and practical suggestions for the emigrants' welfare were finally offered that were associated with the process of values and identities changes in their life.

With development of global network in the 21th century, Korea has recklessly accepted western culture occurred damages to our identity. Development of traditions in a modern way contribute us Korea identity and future vision. This study has studied about combination traditional material and contemporary material with a view to diversified user's desires and individuality. This object shows that function and decoration coexist together, and design reflects mans life and thinking of the age as a reflection of sociocultural phenomena. The purpose of this work to create the object that meets mans requirement and even foresees the possibility of such requirement through converting into various appearances. Different concepts including closed singleness and expansion within open structure coexist one element. also this objects suggest that transformative expressions that simplify or transform, the forms can be freely changed by consumer's emotional changes. Here, light and form are experimented for creating diversified emotions. Considering design as positively responding behavior against the limitations given by environment instead of the solution to simple functional requirement, future design will find Its value more In more active response.

The human facial appearances vary globally and locally according to identity, pose, illumination, and expression variations. In this paper, we propose a hybrid-nonsmooth nonnegative matrix factorization (hybrid-nsNMF) based appearance model to represent various facial appearances which vary globally and locally. Instead of using single smooth matrix in nsNMF, we used two different smooth matrixes and combine them to extract global and local basis at the same time.

Node identity authentication is an essential means to ensure the security of the Internet of Things. Existing blockchain-based IoT node authentication schemes have many problems. A heterogeneous IoT node authentication scheme based on an improved hybrid blockchain is proposed. Firstly, the hybrid blockchain model is designed to make the blockchain and IoT environment more compatible. Then the proxy node selection mechanism is intended to establish a bridge between the ordinary IoT node and the blockchain, building by calculating the trust value between nodes. Finally, based on the improved hybrid blockchain, the node authentication scheme of the model and proxy node selection mechanism establishes a secure connection for communication between nodes. Safety and performance analysis shows proper safety and performance.
