A free-market economic system supported by the progress of the Industrial Revolution 4.0 has given birth to a sharing economy with a disruptive business model. In many ways, this business model is more effective, efficient, and makes it easy for businesses and consumers. However, because disruptive innovation is not asymmetrical with the conventional business that sustains innovation, several regulatory issues arise because it is fundamentally very different and cannot be regulated by standard law. Disruptive innovation may create chaos if it is regulated by norms that are used to regulate conventional business. This research was conducted with a normative method, which examines various theories, principles, laws and regulations to get justification for how the law should govern. The findings of this study are: competition law must be designed pragmatically so that it can keep pace with changes in business models that are rapidly changing. For this reason, it is necessary to shift regulatory authority from the Government to business people to make self-regulation, as a rule, that was born from the agreement of the business actors themselves. Self-regulation is considered more effective in maintaining fair competition, so that the market will be more dynamic, and consumers will be more prosperous.

Like natural climate change on the planet earth, the climate in software development environments is also changing (fast). Like the natural weather, the software environment is also disruptive. As the climate experts alert and suggest taking necessary measures to overcome certain challenges to make this earth a safer and comfortable living place, likewise this article also alerts the relevant stakeholders of software craftsmanship about the dynamic challenges that traditional Software Engineering (SE) with purely "Engineering mind-set" is not capable to respond. Hence, some new thoughts to overcome such challenges are shared. Fundamentally, based on the historical evidences, this article presents the authors' observation about continuous shift from traditional "Engineering-based" software development approaches to disruptive approaches - "Vibrant Softology". The authors see the cause of this shift as disruptive transformational force, which is so powerful that it is uncontrollably diminishing the "Engineering-based" approach from software development environments. The authors align it with climate change analogy. Based on this analogy, the authors feel the need to theoretically re-coin the notion of SE to some new term; perhaps Vibrant/Dynamic Softology (VS or DS). Hence, the authors suggest "a new (disruptive and dynamic) way of thinking is required to develop software". It is worth mentioning that the purpose of article and this new theory is not to disparage the notion of software engineering altogether, rather the aim is to highlight the importance of transformation from SE to its next level (perhaps VS/DS) due to the emerging needs in the software craftsmanship environment.

Core disruptive accidents have been investigated at Korea Atomic Energy Research Institute(KAERI) as part of the work to demonstrate the inherent and ultimate safety of conceptual design of the Korea Advanced Liquid Metal Reactor(KALIMER), a 150 MWe pool- type sodium cooled prototype fast reactor that uses U-Pu-Zr metallic fuel. In this study, a simple method and associated computer program, SCHAMBETA, was developed using a modified Bethe-Tait method to simulate the kinetics and thermodynamic behavior of a homogeneous spherical core over the period of the super-prompt critical power excursion induced by the ramp reactivity insertion. Calculations of the energy release during excursions in the sodium-voided core of the KALIMER were subsequently performed using the SCHAMBETA code for various reactivity insertion rates up to 100 S/s, which has been widely considered to be the upper limit of ramp rates due to fuel compaction. Benchmark calculations were made to compare with the results of more detailed analysis for core meltdown energetics of the oxide fuelled fast reactor. A set of parametric studies were also performed to investigate the sensitivity of the results on the various thermodynamics and reactor parameters.

Since the smart factory has been recently recognized as an industrial core requirement, various mechanisms to ensure efficient and stable operation have attracted much attention. This attention is based on the fact that in a smart factory environment where operating processes, such as facility control, data collection, and decision making are automated, the disruption of processes due to problems such as facility anomalies causes considerable losses. Although many studies have considered methods to prevent such losses, few have investigated how to effectively apply the solutions. This study proposes a Kubernetes based system applied in a smart factory providing effective operation and facility management. To develop the system, we employed a useful and popular open source project, and adopted deep learning based anomaly detection model for multi-sensor anomaly detection. This can be easily modified without interruption by changing the container image for inference. Through experiments, we have verified that the proposed method can provide system stability through nondisruptive maintenance, monitoring and non-disruptive updates for anomaly detection models.

In this paper, we are interested in how creator economy startups allowing creators to make money from doing that they love. So, we look at European creator economy startups among Web3.0 business model landscape surveyed in 2022, because the US is home of Web2.0 giant platforms like YouTube. Totally seventeen European startups are investigated, and the theoretical logic is the disruptive innovation. We firstly review the survey published in 2022 and utilize the theory of the disruptive innovation to design the research framework including questions with each type of the disruptive innovation. In this paper, we firstly show, Kalao and Gem as NFT ecosystem platforms aim at service convenience. Secondly, Talkbase, Passionfroot, Bildr, Customuse, and Earnr aim at providing creator tools for under-skilled customers. Lastly, when it comes direct monetization with a decentralized business model, CrowdPad, Admix, GOALS, Realm, Dropstar, Pianity, Sonomo, Stage11, Miiji, and ReadyPlayerMe are representative. Despite the relatively small data size, the results are meaningful as they contribute to a more profound comprehension of the Web3.0 business models and offer guidance for future research directions.

This study is an investigation into the factors affecting patient dissatisfaction among Saudi hospitals. The selected factors considered for analysis are security of information sharing, operational practices, disruptive technologies, and the ease of use of EHR patient information management systems. From the literature review section, it was clear that hardly any other studies have embraced these concepts in one as was intended by this study. The theories that the study heavily draws from are the service dominant logic and the feature integration theory. The study surveyed 350 respondents from three large major hospitals in three different metropolitan cities in the Kingdom of Saudi Arabia. This sample came from members of the three hospitals that were willing to participate in the study. The number 350 represents those that successfully completed the online questionnaire or the limited physical questionnaires in time. The study employed the structural equation modelling technique to analyze the associations. Findings suggested that security of information sharing had a significant direct effect on patient satisfaction. Operational practice positively mediated the effect of security of information sharing on patient dissatisfaction. However, ease of use failed to significant impact this association. The study concluded that to improve patient satisfaction, Saudi hospitals must work on their systems to reinforce them against the active threats on the privacy of patients' data by leveraging disruptive technology. They should also improve their operational practices by embracing quality management techniques relevant to the healthcare sector.

This study investigates the perception and adoption of ChatGPT (a large language model (LLM)-based chatbot created by OpenAI) among Korean users and assesses its potential as the next disruptive innovation. Drawing on previous literature, the study proposes perceived intelligence and perceived anthropomorphism as key differentiating factors of ChatGPT from earlier AI-based chatbots. Four individual motives (i.e., perceived usefulness, ease of use, enjoyment, and trust) and two societal motives (social influence and AI anxiety) were identified as antecedents of ChatGPT acceptance. A survey was conducted within two Korean online communities related to artificial intelligence, the findings of which confirm that ChatGPT is being used for both utilitarian and hedonic purposes, and that perceived usefulness and enjoyment positively impact the behavioral intention to adopt the chatbot. However, unlike prior expectations, perceived ease-of-use was not shown to exert significant influence on behavioral intention. Moreover, trust was not found to be a significant influencer to behavioral intention, and while social influence played a substantial role in adoption intention and perceived usefulness, AI anxiety did not show a significant effect. The study confirmed that perceived intelligence and perceived anthropomorphism are constructs that influence the individual factors that influence behavioral intention to adopt and highlights the need for future research to deconstruct and explore the factors that make ChatGPT "enjoyable" and "easy to use" and to better understand its potential as a disruptive technology. Service developers and LLM providers are advised to design user-centric applications, focus on user-friendliness, acknowledge that building trust takes time, and recognize the role of social influence in adoption.

An electrochemical reactor was designed and operated to treat the solution containing endocrine disruptive compounds such as phenol and bisphenol A. An experiment involving the electrochemical oxidation of bisphenol A was performed with the use of a dimensionally stable anode (DSA). The apparent current, conductivity, and the gap between cathode and anode were selected as design parameters. The phenol removal rate increased with an increase in apparent current. The bisphenol A removal rate increased with an increase in apparent current efficiency. An increase in the conductivity also led to an increase in the rate of removal of bisphenol A. The gap between cathode and anode did not affect the bisphenol A removal rate or the cathodic current efficiency.

In this paper, I revisit and problematize "blackness" in THH by building on Toni Morrison's call for the theorization of "blackness" in American literature. THH has received much critical attention in the decades that followed its revival, but this paper argues that the meaning of "Africanist presence" has not been adequately addressed in 19th-century women writers' works. This paper is an effort to fill in this gap, and examines the ways in which "blackness" informed and shaped this most popular text of 19th-century America. This paper argues that THH demonstrates contemporary America's fear of "blackness," and rather than celebrating Capitola's feminist credentials or criticizing the lack of sensitivity to racial issues in THH, shows that the significance of the text lies in the ways in which it prophesies an impending national crisis mediated through the disruptive force of Capitola and Black Donald. THH certainly reiterates the popular, contemporary racial paradigms and excludes blacks from the conceptualization of "manhood," and it may seem that the issue of race is subsumed under gender issues when the text continuously privileges gender over race. However, at the same time, Black Donald and Capitola's disruptive energies signify the fear of explosive "blackness," and the disruptive stirrings of "blackness" permeate the novel as the energy that might rupture the seemingly tranquil order of antebellum South. The novel encodes and reflects the fear of blackness in the minds of its readers, and the popularity of this novel foretells nothing less than the explosion of Civil War.
