  • The strategy through visual sense is one of the ways that subject builds the outside world and communicates. The visual sense seems higher level of dependence than the other senses and contributes to intercommunication. For this reason, the desire of image dates back to primitive art and visual image(visual media and visual culture) has dialectically developed in the history of mankind. Visual subject, based on perspective of Renaissance, was moved from God to human beings. Andre Bazin's 'la genese automatique' through technical art has epochally changed the paradigm of visual art and visual culture. From primitive art to photo and film, the image, based on visual sense, has reflected human wish, appealed visual desire and led to evolution of image. In the late 20 century, without dialectical evolution of technology and culture, rapidly progressive digital image has changed social and cultural implication over rational strategy of production and distribution and it strengthened authority of image through visual approach of endless desire. The goal of this study is to analyze the value change of digital image developing a new Renaissance through production, reading, communication, and implication of evolution due to digitalized image, which has evolved as object and tool of desire.

  • Recent advances in genome sequencing technologies have enabled humans to generate and investigate the genomes of wild species. This includes the big cat family, such as tigers, lions, and leopards. Adding the first high quality leopard genome, we have performed an in-depth comparative analysis to identify the genomic signatures in the evolution of felid to become the top predators on land. Our study focused on how the carnivore genomes, as compared to the omnivore or herbivore genomes, shared evolutionary adaptations in genes associated with nutrient metabolism, muscle strength, agility, and other traits responsible for hunting and meat digestion. We found genetic evidence that genomes represent what animals eat through modifying genes. Highly conserved genetically relevant regions were discovered in genomes at the family level. Also, the Felidae family genomes exhibited low levels of genetic diversity associated with decreased population sizes, presumably because of their strict diet, suggesting their vulnerability and critical conservation status. Our findings can be used for human health enhancement, since we share the same genes as cats with some variation. This is an example how wildlife genomes can be a critical resource for human evolution, providing key genetic marker information for disease treatment.

  • Sox protein family, a transcription factor, has been found in whole animal kingdom, and contains a sequence-specific DNA binding domain called high mobility group domain (HMG). The Sox protein family based on the amino acid sequence of HMG domain was classified into 10 groups. Each group of Sox family shows significant conservation from nematode to human. The HMG domain affect to various developmental cell differentiation through binding to enhancer and regulating other transcription factors. Recently, many molecular biologists focus their research on the illustration of Sox-related disease, evolution and phylogeny. Especially, stem cell research with Sox gene family is indispensable field for understanding of their biological functions. The understanding of Sox genes may contribute to understand their role in human genetic disease and whole animal evolution.

  • The cDNA encoding ribosomal protein S4(RPS 4) from an ovary cDNA library of the Japanese monkey (Macaca fuscata) was cloned and sequenced. The RPS4X gene from monkey X chromosome encodes a deduced protein of 263 amino acids and share 99.1% cDNA sequence similarity and 100% amino acid sequence identify with the human RPS4X. Rate of synonymous substitution was higher in RPS4Y than in RPS4X in comparison to the monkey and human. The ratio of synonymous and nonsynonymous substitutions per site indicated that directional selection has nor occurred in RPS4 genes. Phylogenetic analysis using the neighbor-joining method revealed that X and Y-linked RPS4 genes have evolved independently.

  • For raising to the significance of whole Dody form diagnosis, I studied comparatively oriental medicine's whole body form diagnosis, biological evolution and physiognomy. In the oriental medicine, the whole body form diagnosis was recognized a means to deal with 'an individual physiology-pathology' and applied practically 'the typing of whole body form'. The physiognomy was applied to whole body form for the conversion of conception in social science and attached great importance to 'the face of human'. The biological evolution was applied to whole body form for the means by grasping the human individual characteristic, so much as magnified to the size of unconscious body-language(Synergologie, Tells exe.).

  • Worldwide cardiovascular diseases are the major cause of death. Aside from heart transplants, which are limited due to the availability of human donor hearts, artificial hearts are the only therapy available for terminal heart diseases. For various reasons, a total implantable artificial heart is desirable. But the limited space in the human thorax sets rigorous restrictions on the weight and dimensions of the device. Nevertheless, the appropriate functionality of the artificial heart must be ensured and blood damage must be prevented. These requirements set further restrictions to the drive of this device. In the this paper, two optimization methods, namely, the manual parameter variation and Differential Evolution algorithm, are presented and applied to match the specifications of an artificial heart.

  • In vitro evolution is a powerful technique for the engineering of yeast strains to study cellular mechanisms associated with evolutionary adaptation; strains with desirable traits for industrial processes can also be generated. There are two distinct approaches to generate evolved strains in vitro: the sequential transfer of cells in the stationary phase into fresh medium or the continuous growth of cells in a chemostat bioreactor via the constant supply of fresh medium. In culture, evolutionary forces drive diverse adaptive mechanisms within the cell to overcome environmental or intracellular stressors. Especially, this engineering strategy has expanded to the field of human cell lines; the understanding of such adaptive mechanisms provides promising targets for the treatment of human genetic diseases and cancer. Therefore, this technology has the potential to generate numerous industrial, medical, and academic applications.

  • Artificial Intelligence has been a conceptual area for several decades. It has been studied extensively through experiments by the Information Systems community. When Information Systems supported with Information Technology became all pervasive in business and other allied areas, gradually the advancements in Artificial Intelligence also emerged as innovations across domains. Artificial Intelligence by definition is expected to substitute Human Intelligence, thereby making a huge space for innovation. In fact, all processes effected by human intelligence are liable to be replaced by AI which in itself is a massive innovation space. This paper will study the publication's repository (Scopus and Google Scholar from 1983 till 2021) in the area of Artificial Intelligence and innovation, then analyze the trend to gain insight into the evolution of AI as a vehicle for innovation.

  • This paper compares and contrasts the concept of nature and the theory of evolution held by leading synthetic biologists and transhumanists in the post-genomic era. Synthetic biology, which emerged in the early 2000s, aims to design biological systems that perform specific functions with the two key concepts of "rational design" and "directed evolution". However, synthetic biology has also raised serious concerns about the creation of man-made biological materials and the manipulation of the direction and speed of evolution. It is no wonder that transhumanists, who dream of creating new, enhanced human species, have welcomed the arrival of synthetic biology. How, then, can we deal with the nature reinvented by synthetic biology? By what means can one justify research that may affect the process of evolution? What intellectual resources do synthetic biology and transhumanism share in common? What influence would the new trend of commercialization of science and technology exert upon the development of synthetic biology? Addressing those questions, this paper argues that the moral authority of nature can be restored in this post-genomic era.

  • Interest in the origin of the universe and man has historically been one of the central themes of human inquiry. The question of origin is not just a matter of intellectual curiosity, but a matter of human identity and an important matter of human destiny. The traditional model presented in relation to the origin of man is largely the Christian creationism that all things originated from the Creator, the evolutionary theory that everything happened by chance and evolved from lower to higher animals, and the agnosticism that we cannot know anything about the origin. This study deals with the theory of theistic evolution, a combination of creationism and evolutionism. It is argued that the theory of the evolutionary origin was not an immediate creation, although all things originated from God, but through creation through a long evolutionary process. The theory of theistic evolution was proposed by combining two conflicting theories of origin in a Christian way, which has several essential problems, but this study pointed out two. First, the God of the Bible is reduced to the image of being confined to the laws of nature, not the Almighty Creator. Second, by interpreting the events of the Bible symbolically, it results in rejection of historicity. Therefore, it is more rational to choose either evolutionism or creationism rather than the theory of theistic evolution.
