Isolated Habitat Green Corridors: A Proposal of Biological Design -On the Area around the Han River in Seoul -

This think piece approaches urban travel from a mobility humanities perspective, using the example of Seoul, South Korea, a leading metropolis in Asia. The article demonstrates three modes of interpreting urban travel in Seoul: (1) representation by means of mobile video technologies embodying a paradoxical relationship of powers; (2) literary imagination confining a possible mobile community in a restricted region; and (3) philosophical speculation presenting “crossing the Han River” as a spiritual and emotional reproduction of the connection between, and consequential rupture of, heterogeneous territories. The article pays particular attention to the represented, imagined, and speculated dimensions of urban travel, which is understood as a physically practiced and cognitively elaborated production, rather than a predefined movement per se.

Three investigations into the mechanical relevance of wood rays were combined for this article. The main objective was to show, that, apart from physiological functions, rays also significantly influence the radial strength and stiffness of wood. In the first approach twelve deciduous tree species with various proportions of fractions of rays were examined for their transverse tensile strength and stiffness. The second approach was based on the comparison of the radial mechanical properties of wood with a very high proportion of fraction of rays and beech wood with a normal volume. In these two investigations the mechanical relevance of rays could only be deduced indirectly. By isolating big rays of beech and carrying out tensile tests on the tissue, we found direct evidence for the mechanical relevance. The results are discussed with regard to their biomechanical relevance. The importance of a radial reinforcement for the wood is underlined. Moreover, the principle of multi-functionality in nature is emphasized in keeping with a possible transfer of biological design to technical solutions.

Thomas Aquinas offers for his time a novel take on human sexual difference, in that he grounds human sexuality in what we might term a metaphysical biology and accords it a privileged role in the moral life. Though his biology is drawn from Aristotle, which leads Aquinas to make problematic statements on sexual difference, he nonetheless offers a perspective that remains deeply relevant and significant for today. His method or approach of tethering sexual difference first and foremost to our animal-like biological design remains perennial, particularly at a time when many seek to dismiss biology as irrelevant to sexual identity and gender difference. The latest findings of the emerging field of neurobiology, which have uncovered structural differences between the male and female brains, offer key support to Aquinas’s approach. Even more important, he holds, in an unprecedented move, that sexual design and inclination provide a veritable source of moral excellence. He goes so far as to locate the mean of virtue in our sexual design and appetites.
