The proliferation of IoT devices has presented an unprecedented challenge in managing device identities securely and efficiently. In this paper, we introduce an innovative Hybrid Blockchain-Based Approach for IoT Identity Management that prioritizes both security and efficiency. Our hybrid solution, strategically combines the advantages of direct and indirect connections, yielding exceptional performance. This approach delivers reduced latency, optimized network utilization, and energy efficiency by leveraging local cluster interactions for routine tasks while resorting to indirect blockchain connections for critical processes. This paper presents a comprehensive solution to the complex challenges associated with IoT identity management. Our Hybrid Blockchain-Based Approach sets a new benchmark for secure and efficient identity management within IoT ecosystems, arising from the synergy between direct and indirect connections. This serves as a foundational framework for future endeavors, including optimization strategies, scalability enhancements, and the integration of advanced encryption methodologies. In conclusion, this paper underscores the importance of tailored strategies in shaping the future of IoT identity management through innovative blockchain integration.

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.

Kansei engineering or image technology is a tool to analyze relation between product design components and the impression or feeling of human for physical products. This paper attempts to construct the designer\`s aid tool for developing corporate identity(CI) symbol mark based on the hybrid Kansei engineering. It combines the forward Kansei engineering for translating consumer\`s feeling into design components of CI symbol mark and the backward Kansei engineering for evaluating consumer\`s feeling for CI symbol mark. The semantic differential(SD) evaluation experiment is carried out to find the relations between image and design. The backward Kansei engineering system is modelled by fuzzy neural network. This research is expected to contribute to the development of CI symbol mark that correspond to comsumer\`s image.

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.

The objective of this research is to suggest new geometric possibilities in digital architecture by investigating the characteristics of hybridization in digital geometry. The research begins with theoretical background research such as defining hybridization, investigating hybrid thinking, and studying the theory of digital geometry, along with the four conceptual characteristics of hybridization that could be drawn, such as temporality, liquidity, complexity, and connectivity. Based on these characteristics, the generative method of hybrid digital geometric languages such as Blob, Particle, Morph, Loft, and Boolean was analyzed with case research in contemporary digital architecture. As a result, diverse hybrid geometric keywords were extracted; these keywords suggest potential meanings of hybridization such as accidentality, mobility, diversity, and identity. Different elements represent the "mobility" in time by the force and wave, and they are "accidentally" combined in gradual change. The united species in "diverse" characters are seamlessly connected and emerge as a new "identity." The research maximizes the generative possibilities in digital geometry and provides a theoretical basis to apply the digital hybrid methods to architectural design by suggesting the potential meanings and possibilities in hybridization.

In the $21^{st}$ century, technology is a tool for the expansion of the five senses and physical ability that works as an element for posthuman identity. This study analyzes and theorizes on the characteristics of the posthuman body in fashion illustration. The method of this study analyzes documentaries about posthuman and fashion illustration. The results are as follow. Posthuman body types are classed as hybrid body, plastic surgery body, and digital body. The characteristics of the posthuman body are categorized as ultra- functional prosthetic, mythical undifferentiated, radical plastic surgery type and post-physical digitization type. The ultra-functional prosthetic type shows a restored body and upgraded functional body through a machine hybrid, cyborg suit and mannequin hybrid. It is a break from classical gender identity to form a nerve sense extension that displays physical and abstract power. The mythical undifferentiated type shows a therianthropic form, parts of an animal body, radical skin and gender bending. It represents the return to an undifferentiated world, the desire of a powerful being and the possibility of radical transformation. The radical plastic surgery type shows a photomontage of an ideal body, transgendered body, grotesque body marking, absence of partial or overall face organ and the expansion of abnormal body organs. It represents the expression of narcissism, unconscious desire, fantasy, fear and suggests an alternative ideality, sexual attachment and ambiguous gender identity. The post-physical digitization type shows an imperfect form or duplicated ego image through the omission of the body silhouette or detailed form, fragmented image using net, representative self like optical illusion using typography, an imperfect vague silhouette and immaterial body outline through the use of virtual light. It represents the lack of desire, narcissism, fluidity in a virtual space, the continued creation of a new self, ambiguous gender identity and the liberation of environment, sex, and race. Likewise, the posthuman in fashion illustration shows the absence of a species boundary, destruction of classical gender identity, a new personality and virtual self image.

Two-dimensional hybrid codewords are generated by using each row of identity matrix for spatial encoding and nonideal symmetric balance incomplete block design(BIBD) code for spectral encoding. This spatial/spectral optical code-division multiple-access (OCDMA) network uses single-balanced detectors to abstract the desired information bits and to eliminate the multiple-access interference(MAI). Analytical results show that the number of simultaneous users increases significantly by using the proposed hybrid codes.

The Raf, a cytoplasmic serine/thereonine protein kinase, acts as an important mediator of signals involving cell proliferation, differentiation and development. Multiple regulatory elements should participate in the expression of D-raf, Drosophila homolog of human c-raf-1. In order to search regulatory factors involved in the D-raf promoter activation, we accomplished the yeast one-hybrid screening using D-raf promoter region from bp-330 to -309 with respect to the transcription initiation site as bait. After screening, sixteen independent positive clones of ${\beta}$-galactosidase activties were identified and sequenced. Two clones having 94-98% identity with daughterless and one clone having 93% identity with escargot by Blast search among these clones were screened.

Intraspecific sequence variation was detected by polymerase chain reaction (PCR) and direct sequencing of a 350-nucleotide region of the mitochondrial 12S rRNA gene of two natural populations (Han River and Nakdong River) and one hatchery stock (Jinhae Inland Fisheries Institute) of local strain common carp, one Israeli strain of common carp stock from Pukyong National University (PKU), and one hybrid between Israeli strain of common carp female and local strain common carp male from PKU stock. There is little variation in 350 bases of the mitochondrial 12S rRNA gene sequences among 2 natural and 1 hatchery local strain common carp populatins, representing abut 7 to 20 nucleotide differences (less than 6%). The sequence of specimens from Han River was more similar to that from Nakdong River (identity=98.0%) than to that from Jinhae Inland Fisheries Institute (identity=96.3%). Sequence variation between Israeli strain and wild local strain common carp was higher than the variation within natural stocks. The level of variation was ranged from 15.7 to 17.7%. The hybrid showed very similar nucleotide4 sequence of 12S rRNA gene to the sequence of Israeli strain with the identity of 98.9%.

The purpose of this study is to analyze the trend and meanings of the decoration which has appeared on fashion magazines from 1995 through 2005. The method of this study is to analyze 1627 decorations represented in fashion magazine focused on blouse, jacket and one-piece. As a result of this study I drew the following conclusion. First, the decoration reflects a life-style that modern people persue comfort, casual wear. Second, the decoration redefines the feminine identity by fusing different factors of fashion style. Third, the decoration reflects the hybrid tendencies through reconstruction by merging different culture or things.
