  • Hrr25, a casein kinase $1{\delta}/{\varepsilon}$ homolog in budding yeast, is essential to set up mono-orientation of sister kinetochores during meiosis. Hrr25 kinase activity coordinates sister chromatid cohesion via cohesin phosphorylation. Here, we investigated the prophase role of Hrr25 using the auxin-inducible degron system and by ectopic expression of Hrr25 during yeast meiosis. Hrr25 mediates nuclear division in meiosis I but does not affect DNA replication. We also found that initiation of meiotic double-strand breaks as well as joint molecule formation were normal in HRR25-deficient cells. Thus, Hrr25 is essential for termination of meiotic division but not homologous recombination.

  • A theoretical investigation of the origin of the spontaneous firing in the squid axon was done with a mathmatical computer modelling based on the Hodgkin-Huxley equation. It is strongly believed that the existence of calcium ions in the membrane is essential to cause firing. The results of the computer simulation of the modelling indicate that the sites of calcium ions in the membrane might be near the potassium channel and the leakage channel plays an important role in the firing. The orientation of the future research project was suggested. And also, a theoretical investigation of the origin of the firing in the propagating action potential was done in the same way.

  • The purpose of this study was to test various variables that affect CRM performance in order to evaluate CRM performance. The results of the proposed research hypotheses are as follows; First, the IS based factors perform more important roles on system and information quality compared to organizational factors. Second, the variables of IS and planning capability playa role as a parameter. Third, among organizational factors, non-structural factors such as degrees of acceptance of business transition, support of CEO, and customer-orientation perform more important roles on CRM. Fourth, IS based factors have bigger Impact on information quality than system quality. Fifth, it was proven that IS quality, proposed as a parameter and as a dependant variable, and CRM have significant relations.

  • Storytelling plays a very important role in emotional marketing recently. Storytelling marketing emphasizes a unique story and mythical meaning of the product, rather than its practical function. This is a faithful reflection of what the Dream Society has proposed. In this article, we are researching the consumption value system, and analyze various cases focusing on a coffee advertisement. In particular, by delivering a story, we will concentrate on advertising that appeals to utopian values and discusses the actual impact that it brings. If we communicate utopian values to consumers through various stories, business effects will be maximized, which will strengthen the brand image. The originality of this paper is to discuss the theory of consumption value system positively with the concept of storytelling. Therefore, we will draw conclusions as to which orientation is most ideal for storytelling in advertising. Understanding these business models will help you build an effective marketing strategy for the Dream Society.

  • The role of microstructure is quite significant in fretting of Ti-6Al-4V since its material properties depend strongly on crystallographic texture. In this study, we adopt crystal plasticity theory with a 2-D planar triple slip idealization to account fur microstructure effects such as grain orientation distribution, grain geometry, as well as $\alpha$ colony size. Crystal plasticity simulations suggest strong implications of microstructure effects at fretting contacts.

  • The origin of galactic angular momentum is commonly explained as a result of tidal torques of neighbouring protogalaxies on the forming galactic halo. In this context, the environment plays a preponderant role establishing the total angular momentum of present day galaxies. For the last four decades, most of the observational studies focused their attention on the spatial orientation of galaxies in filaments, groups or clusters, leaving behind the magnitude of the angular momentum. We have implemented a simple model to account for the spin of disk galaxies that allow us to obtain an estimate for any galaxy requiring a minimum of information. Applying this method to a sample of galaxies extracted from the Sloan Digital Sky Survey, we have been studying angular momentum distributions of galaxies in different environments. In this talk I will present some results for galaxies immersed in different environments, spanning three orders of magnitude in environmental density, galaxies having nearby companions and clustered galaxies.

  • The role of ESR spectroscopy in the characterization of functional LB films is discussed. Optical absorption were performed on LB films of binary mixtures of three kinds of merocyanine dyes where DS and 6Me-DS form J-like aggregates but not DO in single component films. The observed optical absorption spectra of mixed films were markedly dependant on the combination of dyes. We found the formation of J-aggregates in a mixed merocyanine dyes containing a non J-aggregate forming dye DO, in a single component case. In structural studios, ESR is of particular important in the analysis of molecular orientation of LB films. Development of new functional LB films may provide more cases where ESR spectroscopy will clarify the nature of such films.

  • This paper presents post-buckling responses of a simply supported laminated composite beam subjected to a non-follower axially compression loads. In the nonlinear kinematic model of the laminated beam, total Lagrangian approach is used in conjunction with the Timoshenko beam theory. In the solution of the nonlinear problem, incremental displacement-based finite element method is used with Newton-Raphson iteration method. There is no restriction on the magnitudes of deflections and rotations in contradistinction to von-Karman strain displacement relations of the beam. The distinctive feature of this study is post-buckling analysis of Timoshenko Laminated beams full geometric non-linearity and by using finite element method. The effects of the fibber orientation angles and the stacking sequence of laminates on the post-buckling deflections, configurations and stresses of the composite laminated beam are illustrated and discussed in the numerical results. Numerical results show that the above-mentioned effects play a very important role on the post-buckling responses of the laminated composite beams.

  • Individuals' knowledge does not transform easily into organizational knowledge even with the implementation of knowledge management system in travel agency. A prior research stream emphasizes voluntariness, as a critical factor in knowledge sharing, but pays little attention to its role. We employ theoretical framework and augment it with extrinsic variables, voluntariness of knowledge sharing that are believed to influence customer orientation and market performance of travel agency. Using data on travel agency employee, the authors find considerable results and conclude by discussing prescriptive recommendations for the travel industry.

  • This research investigates the export strategy for pioneering a new market of Advanced Pilot Trainer T-50, a business unit of KAI company, and increasing its market share. The export strategy is proposed based on the Corporate Marketing Model along with the market oriented concept. Specific sales strategies are extracted in consideration of product analysis, market analysis, and integration of product and target market. Therefore, six countries in Africa are selected as the primary target markets on account of their market potentials. In addition, T-50 is repositioned to 'T-50Af' as 'high price competitive and multi-role trainer.' The business implications include the expansion of the market in Africa and the pursuit of the consistent development and growth of T-50.
