This paper presents a hybrid blockchain-based Identity Management Framework for devices in Microgrid. It incorporates the use of a Public and Private Blockchain platform to store and authenticate Microgrid device identities. It also emphasizes the shared responsibility of the manufacturers to provide the first layer of authentication for the devices they produce. Identities of each device are stored in the private and public Blockchain and authenticated using physically unclonable functions (PUF) and cryptographic functions.

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.

A natural hybrid of a probable intergeneric mating between the striped shiner Pungtungia herzi and the stone morocco Pseudorasbora parva (Cypriniformes: Cyprinidae) was captured in the Geumho River, a tributary of the Nakdong River basin in Korea. Morphological characters and DNA sequences were analyzed to verify its hybrid state and identify the parentage of its parent species. The hybrid exhibited a phenotypic intermediacy between the two parent species in the number of vertebrae and the mouth shape. Out of 1,488 base pair (bp) positions of the nuclear recombination activating gene 1 gene (rag1), which has a biparental mode of inheritance, 41-bp substitutions were detected between the two parent species, whereas an electropherogram of the hybrid displayed polymorphic double peaks at all of the base positions, along with one additional one, strongly indicating its hybrid state. Meanwhile, sequence comparison of the mitochondrial cytochrome b gene (mt-cyb) (1,140 bp), which has a maternal mode of inheritance, showed only 5-22-bp differences (97.6-99.5% identities) between the hybrid and Pu. herzi, but as many as 158-168-bp differences (85.2-86.1% identities) between the hybrid and Ps. parva, clearly indicating Pu. herzi as the maternal species. Thus, combined analyses of independent data sets (i.e., morphology and nuclear and mitochondrial DNA sequences) offered convincing evidence for the hybrid state of a naturally occurring hybrid resulting from intergeneric mating between a female Pu. herzi and a male Ps. parva.

This study examines the identities shifting experiences of the ethnic Chinese refugee migrants who have returned to Vietnam. Their complex and hybrid identities as diaspora is an analytical and empirical subject for this study. Since the Vietnamese government implemented the renovation (đổi mới) policy in 1986, the number of overseas Vietnamese returning to Vietnam for visit, work, investment and retirement has been increasing. Among the returnees, many are ethnic Chinese, as there were many Chinese Vietnamese in the Vietnamese refugee diaspora from Vietnam during the 1970s and the 1980s. When they left Vietnam they were called 'the Hoa' (Chinese) or 'Hoa kiều' (overseas Chinese). When they returned, however, they were recognised together with all other returnees into the category of Việt kiều (overseas Vietnamese). Although their 'Chinese' identity had once made them to risk their lives, their 'Vietnamese' identity brought them back to Vietnam at other turning points in their lives. The shifting identity of these returning Chinese Vietnamese has produced dynamic and complex migration stories and an intriguing category of hybrid diaspora.

It is anticipated that, in the 21st century, aesthetic sense will be altered radically with the introduction of new value systems and ethical standards. At the beginning of the 21st century, new aesthetic senses and identities have already emerged and exerted influence to the society, arts and fashion trends. The purpose of this study is to analyze the aesthetic characteristic of the transitional period of the 21st century. This study employed the qualitative analysis and the main aesthetic characteristics of the 21st transitional period were found as hybrid, technicism, neo-retro, new naturalism, and multi-nationalism. The transitional fashion in the 21s1 century mirrors the post-modern trends with diversity and indeterminacy as the basis of changes. It is expected that this pattern will continue to extend persistent and dominant influence to the future fashion industry. In the subsequent study, quantitative analysis wi]1 be conducted to verify the aesthetic characteristics analyzed in this study.

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.

By reading the main character, Rene Gallimard, in M. Butterfly as a spatial metaphor of America, this article examines how homogeneous American national identity of heterosexuality and white masculinity has been reinforced since the cold war and has constituted a crisis of hegemony with the decline of imperialism and how its pathological symptom is shown through the melancholic suicide of Gallimard. This article also argues how the feminine attributes implied in race, gender and sexuality in M. Butterfly are designated and allegorized as an impure, contaminated and ahistorical marker of national integrity in pthe social and material status of the heterosexual American white male. To develop my argument, I read M. Butterfly from a psychoanalytic point of view. Therefore I depend on Freud, Lacan, and Bhabha's psychoanalysis as the theoretical basis. In this paper, I also argue that the homogenized and fixed national identity is splitted and collapsed from within as shown in the Gallimard's melancholy and in the process of splitting the "Third Space" of hybrid subjects for the marginal and the emergent like Song Liling, a homosexual Asian man, can be built "from a space in-between." Therefore Hwang calls into questions conventions of fixed, essentialist identities through the shifting gender identities between Song and Gallimard in M. Butterfly and how identities in the plural are constructed variously in throughly historicized, politicized situations, and these constructions can be complicated by relations of power.

We have previously isolated OsMADS4 gene that is a member of the class B MADS box genes from rice. In this study, another member of the class B MADS box genes was isolated from rice flower by the yeast two-hybrid screening method using OsMADS4 as bait. RNA blot analyses revealed that the clone, OsMADS16, was expressed in the second and third whorls, whereas the OsMADS4 transcripts were present in the second, third, and fourth whorls. These expression patterns of the OsMADS16 and OsMADS4 genes are very similar with those of AP3 and PI, the class B genes of Arabidopsis, respectively. In the yeast two-hybrid system, OsMADS4 interacted only with OsMADS16 among several rice MADS genes investigated, suggesting that OsMADS4 and OsMADS16 function as a heterodimer in specifying sepal and petal identities. We have also isolated OsMADS6 gene using OsMADS1 as a probe. Both are members of the AGL2 MADS family. Various MADS genes that encode for protein-protein interaction partners of the OsMADS6 protein were isolated by the yeast two-hybrid screening method. A majority of these genes belong to the AGL2 family. Sequence Homology, expression pattern, and ectopic expression phenotypes indicated that one of the interaction partners, OsMADS14, appears to be homologous to API, the class A MADS gene of Arabidopsis.

This paper proposes a hybrid architecture algorithm for fast computation of DCT and DFT via recursive factorization. Recursive factorization of DCT-II and DFT transform matrix leads to a similar architectural structure so that common architectural base may be used by simply adding a switching device. Linking between two transforms was derived based on matrix recursion formula. Hybrid acrchitectural design for DCT and DFT matrix decomposition were derived using the generation matrix and the trigonometric identities and relations. Data flow diagram for high-speed architecture of Cooley-Tukey type was drawn to accommodate DCT/DFT hybrid architecture. From this data flow diagram computational complexity is comparable to that of the fast DCT algorithms for moderate size of N. Further investigation is needed for multi-mode operation use of FFT architecture in other orthogonal transform computation.
