As a result of the enormous amount of information that has been collected with E. coli over the past half century (e.g. genome sequence, mutant phenotypes, metabolic and regulatory networks, etc.), we now have detailed knowledge about gene regulation, protein activity, several hundred enzyme reactions, metabolic pathways, macromolecular machines, and regulatory interactions for this model organism. However, understanding how all these processes interact to form a living cell will require further characterization, quantification, data integration, and mathematical modeling, systems biology. No organism can rival E. coli with respect to the amount of available basic information and experimental tractability for the technologies needed for this undertaking. A focused, systematic effort to understand the E. coli cell will accelerate the development of new post-genomic technologies, including both experimental and computational tools. It will also lead to new technologies that will be applicable to other organisms, from microbes to plants, animals, and humans. E. coli is not only the best studied free-living model organism, but is also an extensively used microbe for industrial applications, especially for the production of small molecules of interest. It is an excellent representative of Gram-negative commensal bacteria. E. coli may represent a perfect model organism for systems biology that is aimed at elucidating both its free-living and commensal life-styles, which should open the door to whole-cell modeling and simulation.

Due to the COVID-19 pandemic, the size of the e-commerce has been increased rapidly. This pandemic, which made contact-less communication culture in everyday life made the e-commerce market to be opened even to the consumers who would hesitate to purchase and pay by electronic device without any personal contacts and seeing or touching the real products. Consumers who have experienced the easy access and convenience of the online purchase would continue to take those advantages even after the pandemic. During this time of transformation, however, the size of information source for the consumers has become even shrunk into a flat screen and limited to visual only. To provide differentiated and competitive information on products, companies are adopting AR/VR and steaming technologies but the reviews from the honest users need to be recognized as important in that it is regarded as strong as the well refined product information provided by marketing professionals of the company and companies may obtain useful insight for product development, marketing and sales strategies. Then from the consumer's point of view, if the ratings of reviews are widely diverged how consumers would process the review information before purchase? Are non-converged ratings always unreliable and worthless? In this study, we analyzed how consumer's regulatory focus moderate the attitude to process the diverged information. This experiment was designed as a 2x2 factorial study to see how the variance of product review ratings (high vs. low) for cosmetics affects product attitudes by the consumers' regulatory focus (prevention focus vs. improvement focus). As a result of the study, it was found that prevention-focused consumers showed high product attitude when the review variance was low, whereas promotion-focused consumers showed high product attitude when the review variance was high. With such a study, this thesis can explain that even if a product with exactly the same average rating, the converged or diverged review can be interpreted differently by customer's regulatory focus. This paper has a theoretical contribution to elucidate the mechanism of consumer's information process when the information is not converged. In practice, as reviews and sales records of each product are accumulated, as an one of applied knowledge management types with big data, companies may develop and provide even reinforced customer experience by providing personalized and optimized products and review information.

Despite the limitations of existing security policies due to technological development, companies are unable to actively respond to changes by maintaining a closed security policy. This study classified information security policy into three types: regulatory type policy, advisory type policy, and informative type policy. For each classified policy type, the effect on the information security policy compliance behavior of organizational members was investigated by applying the extended theory of planned behavior, and the moderating effect of information security stress was investigated. SmartPLS 2.0 and SPSS 21.0, which are structural equation modeling techniques, were used to analyze the relationship affecting each factor. As a result of the study, regulatory type, advisory type, and informative type security policies affected organizational members' information security policy compliance behavior, and security stress had an effect on information security compliance attitudes and subjective norms on information security, which are prerequisites for planned behavior theory. gave. This study suggests that various types of corporate information security policies can be applied and that security stress can affect information security behaviors of members.

Recently, there is a need to introduce a Korean-style restriction sandbox system that exempts or suspends existing regulations so that new products or services based on new technologies can be commercialized without restrictions. In response, the government reorganized the relevant statutes to promptly check regulations centering on four fields, including industrial convergence, ICT, FinTech, and regional innovation growth, and to allow experimental, proof and market releases by setting certain conditions(zone, period, scale, etc.). However, despite the same regulatory sandbox application, depending on the nature of the field applied, differences in application subject, whether application of regulatory specifics, system of push ahead decision-making and whether support of financial and taxation are shown. This research is intended to present efficient operation measures for successful settling of Korean-style regulation sandboxes by comparing and analyzing, centering on the Industrial Fusion Promotion Act in the Industrial Convergence Field, ICT field's Information and Communication Convergence Act, FinTech field's Financial Innovation Act and Regional Special Zone Act in the Regional Innovation and Growth Sector.

The rapid development of mobile technology and the improvement of network speed are providing convenience to various services, and mobile shopping malls are no exception. Although efforts are being made to promote sales by combining various technologies such as customized recommendations using big data and specialized personalization services based on artificial intelligence, most mobile shopping malls have the same detailed page information structure including detailed product information. In this context, in this study, it was determined that the content layout of the product detail page and the mobile product detail page layout tailored to the consumer's preference should be presented according to the consumer's preference. Based on Higgins' Regulatory Focus Theory, a study of consumer propensity revealed that the content layout arrangement on a product detail page, when presented in an F-shape, informs the consumer that it is organized. If presented in a Z-shape, vivid information was recognized, and it was examined whether the product attitude and purchase intention were affected. As a result, when the content layout composition was presented as a layout arrangement in the form of a sense of unity and organization, prevention-focused consumers were positively affected by product attitudes and purchase intentions, and promotion-oriented consumers felt freedom. When presented in an arrangement, it was confirmed that the product attitude and purchase intention were affected.

This study scarcity of recent online message promotion limited quantity of messages and time the message is limited controlled variable message whose regulatory focus and promotional discounts depending on the presence of any differences in attitudes and purchase intention appears, was to verify empirically. The results of this study, first, if limited quantity of messages focus on prevention rather than focusing on messages promoting promotion attitudes and purchase intention was higher. Second, the scarcity message is simply, as well as adjust the focus, such as price discounts and promotional activities can be controlled by a variety of points were identified. If the message is particularly limited quantity discounts are not present, rather than the message, the message is presented when the discount promotional attitudes and purchase intention, except that the amplification has been demonstrated. If the message is limited time, however, these discounts are worth the extra promotion on attitudes and purchase intentions are least likely to affect the thing that was found.

Due to liberalization in the early stage, mobile communications market has grown rapidly in the world. However, some dominant operators set higher termination call charges, and thus the market has been distorted and customer welfare has been reduced a lot. The regulation of mobile termination charges is one of key issues of most regulatory agencies in the world. According to the survey, the level of mobile termination charges are quite different from country to country. Why is it so different? This paper investigated the determinants affecting the mobile termination charges for 28 countries by considering country-specific, industry-specific, and regulatory-specific conditions. We found that some regulatory-specific conditions are the most important factors. The rate of pre-paid contract and period of regulation mostly affect the mobile termination charges.

The purpose of our research was to understand the effect of consumers' regulatory focus (i.e., promotion focused vs. prevention focused) on their evaluation of clothing store's VMD and store visiting intention. The results showed that the hedonic and utilitarian benefits of store VMD have significantly a positive impact on visiting intentions. In addition, the relationship between perceived hedonic benefits and store visiting intention was significantly different for PO and PE groups; hedonic benefits explained significantly more of the variance in store visiting intention for promotion-focused group than prevention-focused group. Conversely, utilitarian benefits explained significantly more of the variance in store visiting intention for PE than PO group. These results supported both hypotheses and showed that consumers with a promotion focus have stronger visiting intention toward the VMD with hedonic benefits compared with VMD with utilitarian benefits. Conversely, consumers with a prevention focus have stronger visiting intention toward the VMD with utilitarian benefits compared with VMD with hedonic benefits.
