This study attempts to verify the hypothesis that the interdisciplinary communication patterns may be different according to each disciplines. To put it concretely, it is intended to analyze and compare the subject distribution, the format, the age, the origin and the language of the documents of other disciplines cited in the journal articles according to each disciplines. To test the hypothesis philosophy, sociology and physics as the sample for the three disciplines, that is, humanities, social sciences, and natural sciences are sellected, and the documents cited in the journal articles published in 1966, 1971. 1976, 1981 and 1986 by the Korean Philosophical Association, the Korean Sociological Association and the Korean Physical Society are collected. And then the subject distribution, the format, the age, the origin, the language, and their use rate of the documents of other disciplines cited in the journal articles are investigated, analyzed and compared according to each disciplines. Some findings and conclusions made in the study are as follows. 1. The subject distribution of documents of other disciplines cited and its distribution ratio are different according to each disciplines, that is, humanities high, natural sciences low and social sciences medium. 2. The format and the use rate of documents of other disciplines cited are different according to each disciplines. In the three disciplines book and journal are more used than any format of documents in interdisciplinary communication while in case of the humanities and social sciences book is more used than journal, and in case of the natural sciences journal is more used than book in that communication. 3. The age and the use rate of the cited documents of other disciplines are different according to each disciplines. In case of the social sciences and natural sciences the documents of its last 20 years of publication are cited concentrately, and in case of the humanities the literature age is unconcerned. 4. The origin and the language of the cited documents of other disciplines, and its use rate are different according to each disciplines. In the humanities and natural sciences the documents published in foreign country are cited concentrately, and in the social sciences the home publication documents are more cited than the foreign. The documents of other disciplines in English language are most cited among the documents in any foreign languages in interdisciplinary communication. Putting the three disciplines in order of the use rate of the documents in English language, the natural sciences is high, the humanities medium, and the social sciences low. In the social sciences the use rate of the documents of other disciplines in Korean language is high while in the humanities and natural sciences slight.

As cyber attacks become more intelligent, there is difficulty in detecting advanced attacks in various fields such as industry, defense, and medical care. IPS (Intrusion Prevention System), etc., but the need for centralized integrated management of each security system is increasing. In this paper, we collect big data for intrusion detection and build an intrusion detection platform using deep learning and CNN (Convolutional Neural Networks). In this paper, we design an intelligent big data platform that collects data by observing and analyzing user visit logs and linking with big data. We want to collect big data for intrusion detection and build an intrusion detection platform based on CNN model. In this study, we evaluated the performance of the Intrusion Detection System (IDS) using the KDD99 dataset developed by DARPA in 1998, and the actual attack categories were tested with KDD99's DoS, U2R, and R2L using four probing methods.

Tandem or multijunction solar cells (MJSCs) can convert sunlight into electricity with higher efficiency (η) than single junction solar cells (SJSCs) by dividing the solar irradiance over sub-cells having distinct bandgaps. The efficiencies of various common SJSC materials are close to the edge of their theoretical efficiency and hence there is a tremendous growing interest in utilizing the tandem/multijunction technique. Recently, III-V materials integration on a silicon substrate has been broadly investigated in the development of III-V on Si tandem solar cells. Numerous growth techniques such as heteroepitaxial growth, wafer bonding, and mechanical stacking are crucial for better understanding of high-quality III-V epitaxial layers on Si. As the choice of growth method and substrate selection can significantly impact the quality and performance of the resulting tandem cell and the terminal configuration exhibit a vital role in the overall proficiency. Parallel and Series-connected configurations have been studied, each with its advantage and disadvantages depending on the application and cell configuration. The optimization of both growth mechanisms and terminal configurations is necessary to further improve efficiency and lessen the cost of III-V on Si tandem solar cells. In this review article, we present an overview of the growth mechanisms and terminal configurations with the areas of research that are crucial for the commercialization of III-V on Si tandem solar cells.

With the advent of the Fourth Industrial Revolution, there is an increasing demand for interdisciplinary studies in the realm of university education. Accordingly, this study sought to explore learners' perceived expectation factors for a modular curriculum, one of the primary strategies for curriculum revision in interdisciplinary departments, by applying the Expectation Theory. Learners' perceptions were measured pre and post during the second semester of 2022. The results confirmed that among the expectation factors, the selection factor significantly decreased after the course compared to before. Changes in the understanding and perceived difficulty level of tool utilization within the course may have influenced these results. The significance of this study lies in providing direction for curriculum revisions in interdisciplinary departments by analyzing learners' perceptions of the modular curriculum. Specifically, curriculum design should focus on reducing difficulties and cognitive burdens associated with educational tool utilization. Furthermore, considering that students' prior experience and understanding of educational tools can impact educational outcomes, it is crucial to factor these elements when designing a modular curriculum.

Propagation time on permissionless blockchain plays a significant role in terms of stability and performance in the decentralized systems. A large number of activities are disseminated to the whole nodes in the decentralized peer-to-peer network, thus causing propagation delay. The stability of the system is our concern in the first place. The propagation delay opens up opportunities for attackers to apply their protocol. Either by accelerating or decelerating the propagation time directly without proper calculation, it brings numerous negative impacts to the entire blockchain system. In this paper, we thoroughly review and elaborate on several parameters related to the propagation time in such a system. We describe our findings in terms of data communication, transaction propagation, and the possibility of an interference attack that caused an extra propagation time. Furthermore, we present the influence of block size, consensus, and blockchain scalability, including the relation of parameters. In the last session, we remark several points associated with the propagation time and use cases to avoid dilemmas in the light of the experiments and literary works.

p-type Tunnel Oxide Passivating Contacts (TOPCon) solar cell is fabricated with a poly-Si/SiO_x structure. It simultaneously achieves surface passivation and enhances the carriers' selective collection, which is a promising technology for conventional solar cells. The quality of passivation is depended on the quality of the tunnel oxide layer at the interface with the c-Si wafer, which is affected by the bond of SiO formed during the subsequent annealing process. The highest cell efficiency reported to date for the laboratory scale has increased to 26.1%, fabricated by the Institute for Solar Energy Research. The cells used a p-type float zone silicon with an interdigitated back contact (IBC) structure that fabricates poly-Si and SiO_x layer achieves the highest implied open-circuit voltage (iV_oc) is 750 mV, and the highest level of edge passivation is 40%. This review presents an overview of p-type TOPCon technologies, including the ultra-thin silicon oxide layer (SiO_x) and poly-silicon layer (poly-Si), as well as the advancement of the SiO_x and poly-Si layers. Subsequently, the limitations of improving efficiency are discussed in detail. Consequently, it is expected to provide a basis for the simplification of industrial mass production.

This study examines a study of communication factor in Lunyu, as a communication text, in terms of communicator, audience, message, communication factor, communication text, interdisciplinary research. In many respects, it is generally accepted that Lunyu have been the generic references of the Oriental culture. Lunyu consider ethics, logic, and practicability as the qualifying requirement of communicator, asserting that communicator should speak true language, like a "chuntzu"(君子) does, and should also put their language into practice. The audience's attitude and method as contained in Lunyu are that hearers should have sharp ears for language, hear selectively the right language, and use the language suitable to the situation. It is also emphasized that the Hearer should actively lead in the situation of transactional communications. In Lunyu, one property of message is that language, which determines the rise and fall of a nation and is also the basis of judgement for other people, should comply with ethics and reasons and sould also be put into practice. In other words, credible message, as the practice of language, is the practical requirement of ethics and the qualification of a "chuntzu"(君子, superior man) in ruling the nation or conducting one's life.
