  • Spent nuclear fuel, which can degrade during long-term storage, must be transported intact in normal transport conditions. In this regard, many studies, including those involving Multi-Modal Transportation Test (MMTT) campaigns, have been conducted. In order to transport the spent fuel safely, a tie-down structure for supporting and transporting a cask containing the spent fuel is essential. To ensure its structural integrity, a method for finding an optimum conceptual design for the tie-down structure is presented. An optimized transportation test model of a tie-down structure for the KORAD-21 metal cask is derived based on the proposed optimization approach, and the transportation test model is manufactured by redesigning the optimized model to enable its producibility. The topology optimization approach presented in this paper can be used to obtain optimum conceptual designs of tie-down structures developed in the future.

  • A varying degree of eccentricity always exists in the initial configuration of a nuclear fuel rod. Its impact on traditional LWR fuel is limited as the radial gap closes relatively early during irradiation. However, the effect of misalignment is expected to be more relevant in rods with highly conductive fuels, large initial gaps and low conductivity filling gases. In this paper, we study similar characteristics in the experimental setup of two fuel disc irradiation campaigns carried out in the OECD Halden Boiling Water Reactor. Using the multi-dimensional fuel performance code OFFBEAT, we combine 2-D axisymmetric and 3-D simulations to investigate the effect of eccentricity on the fuel temperature distribution. At the same time, we illustrate how the advent of modern tools with multi-dimensional capabilities might further improve the design and interpretation of in-pile separate-effect tests and we outline the potential of such an analysis for upcoming experiments.

  • The Republic of Korea (ROK) has had a successful experience in greening its land because of strong state policy and public participation. This paper aims to analyze the interest positions, participation, and accountability of multiple actors in the process of greening movements in the ROK. These movements were divided into two phases: forest rehabilitation (1973-1997) and urban greening (1998-2017). During the first phase, farmers caused deforestation by slash-and-burn farming and illegal logging, and governmental agencies acted as helpers controlled the farmers' deforestation activities. During the second phase, government agencies and enterprises caused deforestation with urban development projects, including construction of housings and roads. Multiple actors including citizens, NGOs, and enterprises helped urban greening through campaigns, donations, and monitoring. As a result, managing interest positions is significant to motivate multiple actors to participate in the greening movement. Participation with clear accountability is meaningful for successful greening. Therefore interest-based participation requiring accountability contributes to greening. This phenomenon indicates interconnection for interest positions, participation and accountability should be considered in designing greening policies.

  • This paper focuses on historical instances of iconoclasm after the Reformation to reveal how iconoclasm had greatly contributed to the formation of the Protestant mindset in the early modern times. During the English civil war, when iconoclastic campaigns and movements were in full tide, the paper argues that the notions of novelty and progress were more positively accepted among radical religious groups. To put it in another way, the paper suggests a different way of looking the formation of Protestant habitus by giving accounts of how iconoclastic impulses spurred diverse religious groups during the civil war to break the mold of conservative thinking and to revolutionize the print culture hitherto based on patronage and served as a buttress for status-quo. From this analysis, then, we are ledto the different portrait of the protestant in the seventeenth century, whose mindset was not quite as solitary and guilt ridden as Max Weber would have us believe.

  • To overcome the ongoing COVID-19 pandemic, vaccination campaigns are the highest priority of majority of countries. Limited supply and worldwide disproportionate availability issues for the approved vaccines, together with concerns about rare side-effects have recently initiated the switch to heterologous vaccination, commonly known as mixing of vaccines. The COVID-19 vaccines are highly effective in the general population. However, none of the vaccines is 100% efficacious or effective, with variants posing more challenges, resulting in breakthrough cases. This review summarizes the current knowledge of immune responses to variants of concern (VOC) and breakthrough infections. Furthermore, we discuss the scope of heterologous vaccination and future strategies to tackle the COVID-19 pandemic, including fractionation of vaccine doses and alternative route of vaccination.

  • In order to promote cervical cancer prevention behaviors of female college students, this study aims to explore factors that influence cervical cancer prevention behavior of female college students. Specifically, this study examined mediating roles of knowledge and self-efficacy in predicting behavioral intention to prevent cervical cancer. An online survey was conducted on female college students. Analysis of 236 female college students' responses revealed that health status influenced behavioral intention to prevent cervical cancer indirectly through knowledge and self-efficacy. Exposure to Internet media influenced behavioral intention to prevent cervical cancer directly and indirectly through knowledge and/or self-efficacy. Knowledge influenced behavioral intention to prevent cervical cancer directly and indirectly through self-efficacy. Based on the findings of this study, we provided implications for planning of educational programs and campaigns to promote the cervical cancer prevention behaviors of female college students.

  • Seeded marketing campaign (SMC) is a newly created type of marketing activities with the widespread use of social media. Previous research has examined to find out the optimal seeding strategy that yields the best outcome from the campaign. This research explores the relationships between the characteristics of the seeded influencer and user engagement. The data consists of information from 1062 seeded Instagram posts posted in September 2020 in Korea and 778 seeded influencers who posted those contents. Analyzed by negative binomial regression, our quadratic model suggests that the relationship between user engagement and the number of followers of the seeded influencer draws an inverted U-shape, indicating influencers with greater number of followers may not always be the best choice for the marketers. Moreover, this research shows that the negative marginal impact coming from the huge number of followers can be attenuated when the influencer is an expert of the seeded product.

  • Though crowdfunding has emerged as a cost-effective means to market innovative products and a channel for financial resource acquisition, our understanding about what makes a successful crowdfunding is still limited. This study is motivated by the presence of the inconsistency that both entrepreneurs and investors pay more attention to capabilities required for developing prototype products rather than capabilities needed to deliver the promised products in crowdfunding. By drawing insights from studies about liability of newness and legitimacy in institutional theory, this study argues that startups can overcome the liability of newness, earn investor trust, and successfully complete crowdfunding campaigns by effectively presenting visible and invisible capabilities. This study presents a set of testable propositions predicting the likelihood of crowdfunding success and explains the theoretical and practical value of the proposed conceptualization of startup capabilities.

  • This paper addresses the central issue of whether it is effective for a firm to discourage the purchase of its own product in order to support a social cause. The objectives of this study were: a) to examine whether a cause-related self-prevention ad would stimulate more positive evaluations compared to promotional ad, particularly when the product category is more negatively socially accepted; and 2) to determine if a negative attitude toward the product could induce a boomerang effect of a selfprevention ad. Results from three experiments revealed that socially responsible prevention campaigns against firm's own product may be more effective for the product category negatively associated with social concerns or welfare. If products are more limited in the social context, communications of product prevention are beneficial to improve the public image of the brand. However, the self-hurting approach may be inappropriate for potential customers who currently possess a strong negative attitude toward the product.
