  • This study evaluates the properties of porous concrete for pavement according to content of silica fume and steel fiber. The results of the test indicate that in every condition, the void ratio and the coefficient of water permeability of porous concrete for pavement satisfy both the domestic standards and proposition values. Among the properties of strength, the compressive strength satisfies the standards in the specification of KNHC as for every factor of mixture but in the case of the flexural strength, more than $0.6vol.\%$ of steel fiber satisfied the JCI proposition values. The case when silica fume and steel fiber are used simultaneously presents the strongest durability and Noise Reduction Coefficient is 0.48 to prove that it possesses almost $50\%$ sound absorption.

  • In this article, we develop a 'dynamic' approach to manufacturing improvement, based on perspectives of manufacturing learning and decision theory. First, we present an alternative definition of production system consistent with a decision-theoretic perspective: the system consists of structural, infra-structural, and decision making constructs. A primary proposition is that learning capability possessed by a manufacturing system be prerequisite for the system to improve its manufacturing performance through optimal controlling of the three constructs. To support the proposition, we elaborate on a mathematical representation of "learning" as defined in an applied setting. We show how the learning capability acts as an integrating force ameliorating the trade-off between two key manufacturing capabilities, i.e., process controllability and process flexibility.exibility.

  • This study, as part of the research on mathematics teacher knowledge analyzed the differences in understanding and familiarity on geometric knowledge of middle-high school teachers. Through this study, survey was carried out using a questionnaire and examination for 80 middle-high school teachers. As the result, differences between familiarities about believing in knowing about the proposition, and actually understanding why the proposition is established, was big. These results can provide us implications on the education of teachers and pre-service teachers of middle-high school.

Michel Foucault and historiography of architecture -History of architecture back in the general history of techne- (미셸 푸코와 건축 역사서술 -테크네의 일반사에 자리잡은 건축의 역사-)

  • This study aims to examine the brief statement about the historiography of architecture by the French philosopher Michel Foucault and the possibility of a historical description according to his method. His historiographic proposition, "the history of architecture back in (the) general history of techne," is a novel idea not only for his contemporaries but also for us. To grasp the meaning of Foucault's proposition, we begin by considering his position with regard to architecture or architectural space in certain discussions till then. We then compare his standpoint on historical recognition with other viewpoints about historical narratives that can be found in books written since 1930. Finally, we interpret the concept of "techne" in the sense of "relation," whose objectivation is for him his concern on architecture and examine possible aspects and their limits.

  • Since whole-genome duplication (WGD) of diploid Chrysanthemum nankingense and de novo assembly whole-genome of C. seticuspe have been obtained, they have afforded to perceive the diversity evolution and gene discovery in the improved investigation of chrysanthemum breeding. The robust tools of high-throughput identification and analysis of gene function and expression produce their vast importance in chrysanthemum genomics. However, the gigantic genome size and heterozygosity are also mentioned as the major obstacles preventing the chrysanthemum breeding practices and functional genomics analysis. Nonetheless, some of technological contemporaries provide scientific efficient and promising solutions to diminish the drawbacks and investigate the high proficient methods for generous phenotyping data obtaining and system progress in future perspectives. This review provides valuable strategies for a broad overview about the high-throughput identification, and molecular analysis of gene function and expression in chrysanthemum. We also contribute the efficient proposition about specific protocols for considering chrysanthemum genes. In further perspective, the proper high-throughput identification will continue to advance rapidly and advertise the next generation in chrysanthemum breeding.

  • Storytelling marketing is attracting attention as a customer-oriented brand communication activity in an over-competitive marketing environment that is overflowing with products and without specification of brand and products. This case study is researched for USP strategies in terms of excitability, storytelling, and interactivity, which are components of storytelling marketing to positively interact with customers for effective and sustained competition. And this research could be helped effective and sustained competition for brand and productions.

  • Although the two types of currencies compete, the possibility of a virtual currency price bubble is diagnosed by assuming an economic model with currencies (won, virtual currency) that are intrinsically worthless. The won is supplied by the central bank to achieve the price stability target, while the supply of virtual currency increases by a fixed number. According to the basic price theory equation, as a simple proposition, cryptocurrency prices form a Martin Gale process [Schilling and Uhlig, 2019, p.20]. Based on the existing theoretical proposition, we applied the variance ratio verification method [Linton and Smetanina, 2016] and a simple technical chart method for empirical analysis. For the purpose of this study, the possibility of a bubble was empirically analyzed by analyzing the price volatility formed in the Korean virtual currency market over the past year, and brief policy implications for this were presented.

  • Researchers do not fully understand consumers' responses to negative co-branding events; thus, they report inconsistent evidence regarding the negative impact on the partnering brands. Our research bridges a gap in this research stream, and answers an important question: When a service failure occurs, could the two different models of consumers' brand schema change affect their negative perception of each brand partner? By using a theoretical and mathematical modeling approach, we offer two propositions. The first proposition shows that, under consumers' book-keeping cognitive process, the negative spillover effect occurs for both brands. The second proposition argues that, when the sub-typing model is assumed, it is possible that one brand suffers while the other escapes the blame for the failure. To our knowledge, this is one of the first few studies to identify circumstances in which a negative spillover effect may or may not occur to brand partners in co-branding service failures.

  • Product involvement is an important factor in consumer evaluation of co-branding. However, academic discussions over this factor have largely been neglected. This paper bridges this gap and investigates how product involvement moderates the strength of the reciprocal effect on each brand partner. We validate two theory-driven propositions by using a theoretical modeling approach. Proposition 1 explains that the negative reciprocal effect on partnering brands is stronger in the scenario of higher-involved categories than in lower-involved categories. Proposition 2 argues that the positive reciprocal effect on partnering brands can be more significant in the case of lower-involved categories than in higher-involved categories. To the best of our knowledge, we are the first to explore the influence of product involvement on reciprocal effects in the scenario of a moderately-incongruent co-branding alliance.
