  • This paper presents the radio propagation effects in the shadow region due to the presence of obstacle, like building and tree, along the path at the B-WLL band. Using the Uniform Theory of Diffraction(UTD), the total field was obtained as the sum of contributions with diffraction ray from the each obstacle's edge, the direct ray, and the reflected rays from ground. The normalized signal level(in ㏈) is calculated with the parameters of the base station elevation and the distance between obstacle and receiver. This results are used to provide the suitable radio cell planning and coverage prediction in the area of shadow region.

  • Cell adhesion is a coordinated process involving initial binding of integrin receptors to extracellular matrix (ECM), recruitment of adhesion proteins, and focal adhesion assembly. The formation of mechanically stable focal adhesion assembly of cells within surrounding ECM is a key parameter to direct numerous cellular functions including cell migration, differentiation, and apotosis. With current cell adhesion assays, it is difficult to understand contributions of each coordinated event on evolution of cell adhesion strengthening since cells spontaneously spread upon their adhesion to the substrate, thus remodeling their cytoskeletal structure. In this presentation, novel approaches for analysis of cell adhesion strengthening process based on the combination of mechanical device, micro-patterned substrates, and molecular biological techniques will be discussed.

  • Purpose - This study addresses an acquisition's impact on a firm's strategic relationship based on findings of existing academic studies and theoretical assertions. Through examining existing research results and theoretical grounds for an acquisition's impact on various stakeholders, this study indirectly approaches the impact on stakeholders including alliance partners. Research design, data, and methodology - This research identified a variety of related theoretical foundations and empirical studies. Research objectives of prior studies mainly focused on merging firms and direct participants of acquisition activity. In addition, academic attention on the impact on rival firms has recently been growing. However, little research on alliance partners was found. Prior studies simultaneously employed event study methodology and cross-sectional analysis to make further theoretical contributions. Results and Conclusions - Based on the findings of prior studies, this research proposed a complementary research model for future academic inquiry into the impact of an acquisition on an alliance partner's return and for predicting an acquisition announcement's effect on alliance partners.

  • This article deals with the customers' complaint behaviors and complaint management for cosmetic customers. The general aim is to analyze the changes of complaint behavioral responses before and after the complaint management experiences, describing customers' response patterns in terms of how they are influenced by the service justice and satisfaction of complaint management. The most relevant contributions from the related theoretical work indicate that the better the customer complaints are managed, the higher the level of possibility for customers to complaint, especially for public and direct responses(complaint behaviors). The only exception, although the statistical significant support was not found, is the private response, as the chance gets lower than before experiencing the complaint management.

  • The function of a diagnosis is to provide information that can guide treatment. The physicians provides only a limited amount of information that is pertinent to the physical therapy management of the patient. In only a very general way does the diagnosis direct the physical therapy's treatment. Thus, by the members of the physical therapy profession recognizing their role and responsibility to become diagnosticians, they can begin to classify signs and symptoms more actively and develop the categories that will enhance the effectiveness of their practice and their contributions to health care.

  • Association of cytochrome c with anionic membranes involved both electrostatic and hydrophobic interactions and their relative contributions depended on the physical state of the membrane and the redox state of cyto-chromec.Hydrophobic interaction was favored by the membranes in gel phase, by the membranes with a large curvature, and by the membranes with a high surface charge density. Ferrocytochrome c was less dissociable by NaCl than ferricytochrome c suggesting that a lower protein stability is beneficial for hydrophobic interac-tion.Hydrophobic interaction induced larger structural perturbations on cytochrome c as monitored by the loss of the Fe-Met bond and by the increase in the distance between heme and Trp-59. When bound to anionic mem-branes,spin-labeled cytochrome c showed an electron paramagnetic resonance spectrum with two or more components, providing a direct evidence for multiple conformations of bound cytochrome c.

  • This paper estimates the effects of transport (road and rail) & energy and ICT infrastructure (telephone, mobile, and broadband) on GDP growths in neighboring countries as well as own countries. We confirm positive direct contributions of infrastructure, access to Internet, and human capital on economic growth. The spatial panel regression models indicate that there exist positive externalities of the broadband infrastructure and human capital, and these results are robust regardless of the choice of spatial weight matrices. Our findings on spillover effects of infrastructure suggest the key role of neighboring countries' infrastructure on own country's economic growth.

  • Symbiotic stars are wide binary systems of a white dwarf and a mass losing giant, exhibiting various activities mainly attributed to accretion of a fraction of slow stellar wind emanating from the giant. We perform 3 dimensional hydrodynamical simulations using the FLASH code to investigate the formation and physical structures of an accretion disk in symbiotic stars with binary separation in the range of 2-4 au. Radiative cooling is introduced in the flow in order to avoid acute pressure increase in the vicinity of the accretor that may prevent stable disk formation. By setting the same density condition in front of the bow shock generated in two different velocity fields, the role of ram pressure balancing between the disk and the wind is examined. We find that three main streams (direct stream from the giant, stream following the accretion wake, and stream passing through the bow shock front) all feed the disk, and their individual contributions on the mass accretion onto the white dwarf are explored.

  • This research attempts to resolve the construction delay issues of indirect delays by developing the "Delay Responsibility Determination Model" (DRM) based on probabilistic risk analysis. DRM is envisioned to provide a way of quantitatively analyzing impacts of delayed activities while considering both direct and indirect influences. With the successful development of DRM, it would be possible to present relative probabilistic measures to all the related stakeholders in terms of their contributions to schedule delays. Upon the development completion of DRM, "Korean Construction Delay Claim/Dispute Resolution Protocols" will also be prepared to facilitate the effective use of DRM.

  • Contemporary Buddhist scholarship in Korea has been strongly affected by its origins in the Victorian era, when Western religious scholars sought to rationalize and historicize the study of religion. Modern Korean scholars, trained within the Western scholarly paradigm, share this prejudice which tends toward the rational. The result is a skewed understanding of Buddhism, emphasizing its philosophical and theoretical aspects at the expense of seemingly "irrational" religious elements based on the direct experience of meditation practice. This paper seeks to look at the historical context in which modern Korean Buddhist scholarship had been shaped during the colonial period of Japan. Two case studies will be examined particularly in the light of post-colonial perspectives of Buddhist studies: the case of Jonghong Bak(1903-1976) and the case of Donghwa Gim(1902-1980), two pioneering scholars in the field of Buddhist studies. They share similarities as well as differences. Both were born and active at almost the same period, during which Korean peninsula experienced modernization forced upon by Japanese colonialism. And thus, the experience of colonialism and modernization brought them into conflict between tradition and modernity. Their responses, however, were different. Pak, originally trained in Western philosophy, especially German philosophy, wanted to study Korean Buddhism in the context of the so-called Korean Philosophy per se. He was motivated to seek for the national and cultural identity of Korea. And thus his scholarship on Korean Buddhism naturally led him to look for an original Korean Buddhism distinct from the Buddhism of India, China and Japan. On the other hand, Gim, who became a monk in his youth, later went to Japan for college where he was exposed to modern Buddhist scholarship. He was the first to introduce modern Buddhist scholarship to Korea, and since then, contemporary Korean Buddhist scholarship owes much to his contributions. Despite his contributions to contemporary Korean Buddhist scholarship, if we look at his efforts in the light of post-colonial perspective, his ideas need to be reevaluate.
