Grotesque, which has often emerged as a breakthrough in Western art to protest rational and classical pure beauty, is often seen in modern art. Grotesque, along with the concept of pendulum, appears in infinitely expanded forms across cultures, arts, and society. In particular, transformed body images through deformatization and deformatization of the body are interpreted as strong rejections that seek to break away from formalized beauty. The main purpose of this study is how the body reproduced through body deformation, distortion, and bonding in Dimitris Papaioannou's work can be interpreted within the grotesque category. To this end, he examines the Grotesque discourse and modern meaning underlying the interpretation of the work and identifies how the fragmented and expanding body, which is currently actively discussed in the dance world, has an interaction with Grotesque. It selects , , , and , which are the main attributes of the grotesque, focus on conflicting familiarity, life, hatred, and beauty. Based on this, we would like to confirm that in contemporary dance, the reconstructed body reveals concealed things rather than expressing an unrealistic fictional world, and seeks new possibilities beyond boundaries as well as reconsider existing aesthetic views.

The voltages mainly used in ships are 450 [V], 6.6 [kV], and 11 [kV], and an earthed system is applied to ensure the stability of the power distribution system. In general, low-voltage ships using 450 [V] apply an unearthed system, while high-voltage ships using 6.6 [kV] or 11 [kV] use a high-resistance earthed system. When an earth fault occurs in a ship's power distribution system, the voltage of the healthy phase increases to the line-to-line voltage or higher, which causes an excessive impact on the insulation of the cable. Thus, analyzing this behavior is very important. In this paper, we investigate the characteristics of the line-to-earth voltage variation according to earth faults and a recognition procedure of a faulty phase using the symmetrical coordinate method for a high-resistance earthed system and unearthed system. A mathematical model of the line-to-earth voltage was derived through the symmetric coordinate method, and the ship voltage for simulations was selected as 6.6 [kV] and 450 [V]. A MATLAB simulation proved that this method can determine the highest increase of the line-to-earth voltage, which leads by 120° on the faulty phase, and it accurately judges the faulty phase in both earthed systems.

In this paper, we investigated the principle of appropriation by which mythology and literature were accepted in the unique religious context of The Canonical Scripture (Jeongyeong 典經). First, we knew that almost all of the gods that appeared in the discourse of Kang Jeungsan (姜甑山) were related to Eastern Yi (東夷) mythology and deeply rooted in folklore. This is because the cultural tendency and historic consciousness of Kang Jeungsan was influenced by Danhakpa (the Danhak School 丹學派). Secondly, when we investigated the acceptance of literature into The Canonical Scripture, we discovered that Tang Poetry (唐詩), Romance of the Three Kingdoms (Sanguoyanyi 三國演義), and Journey to the West (Xiyouji 西遊記) were widely accepted in Kang Jeungsan's discourse. These works were used in diverse ways such as predictions, healing, and meditation. We knew that popular classical work like these were religiously appropriated in the context of The Canonical Scripture. Lastly, we investigated the mechanisms by which mythical and literary imagination was transformed into the Jeungsanist religious movements. Those mechanisms included the magical power of letter and images, sense-cognition of poetry, and the representational ability of mimesis. In conclusion, mythical and literary imagination helped Jeungsanist religious movements gain popularity and spread Kang Jeungsan's soteriology. This is especially true of how it transformed into unique religious techniques which functioned as key elements of the Reordering Works (公事).

The Accommodational missionary method adopted by the Jesuit missionaries who came to China in the late Ming and early Qing dynasty is called the Accommodation and Naturalization and is based on the Poetry. The terms they borrowed were 'Di(Emperor Above)' and 'Tian(The heaven)', the key terms of Confucianism. Although 'Di' was a new transcendent concept, its status was downgraded in the political upheaval, and 'Tian' was rather elevated. However, both of these concepts gradually transformed into philosophical concepts that directly affect real life. The two terms borrowed to express the priesthood could not contain the uniqueness of Christianity, and Christianity was interpreted as an extension line of Confucianism thinking, reduced to an adjunct of Confucianism, and was not indigenous to the depth of ideology. A rational philosophical inquiry could not have played a full role in guiding the Chinese into the true Christian 'faith' unless it is paired with the great teachings of revelation. It is necessary to analyze these results soberly to find problems and to try various studies to explore ways to open up new horizon for Christian missionary work.

A method of constructing a war simulation based on Bayesian Inference was proposed as a method of constructing heterogeneous historical war data obtained with a time difference into a single model. A method of applying a linear regression model can be considered as a method of predicting future battles by analyzing historical war results. However it is not appropriate for two heterogeneous types of historical data that reflect changes in the battlefield environment due to different times to be suitable as a single linear regression model and violation of the model's assumptions. To resolve these problems a Bayesian inference method was proposed to obtain a post-distribution by assuming the data from the previous era as a non-informative prior distribution and to infer the final posterior distribution by using it as a prior distribution to analyze the data obtained from the next era. Another advantage of the Bayesian inference method is that the results sampled by the Markov Chain Monte Carlo method can be used to infer posterior distribution or posterior predictive distribution reflecting uncertainty. In this way, it has the advantage of not only being able to utilize a variety of information rather than analyzing it with a classical linear regression model, but also continuing to update the model by reflecting additional data obtained in the future.

This study explored the possibility of introducing modern physics into the elementary school science curriculum. The study discussed the need of introducing modern physics to elementary school students and examined the results of certain projects and studies on teaching modern physics to elementary school students. Furthermore, this study proposes several teaching and learning techniques to introduce modern physics into the elementary school science curriculum. Modern physics can be linked to various everyday situations experienced by students and can increase their interest and curiosity in science. Additionally, introducing modern physics to elementary school students who are yet to establish a background on the classical view of nature can help them build a new perspective. Recently, several global projects to introduce modern physics at the elementary level have also reported positive results regarding the increase in student understanding and interest in modern physics. The study briefly proposed specific topics and teaching and learning techniques that could be suitable for the elementary school level. These proposals are expected to advance discussions on the possibility of introducing modern physics. However, appropriate follow-up studies are warranted to confirm the possibility and effectiveness of this initiative.

In this study, a nonlinear truss finite element is developed to analyze structures with negative Poisson effect-induced tensile buckling. In general, the well-known buckling phenomenon is a stability problem under a compressive load, whereas tensile buckling occurs because of local compression caused by tension. It is not as well-known as classical buckling because it is a recent study. The mechanism of tensile buckling can be briefly explained from an energy standpoint. The nonlinear truss finite element with a torsional spring is formulated because the finite element has not been reported in the literature yet. The post-buckling analysis is then performed using the generalized displacement control method, which reveals that the torsional spring plays an important role in tensile buckling. Structures that mimic a negative Poisson effect can be constructed using such post-buckling behaviors, and one of the possible applications is a mechanical switch. The results obtained are compared to those of analytical solutions and commercial finite element analysis to assess the validity of the proposed finite element model. The numerical results show that the developed finite element model could be a viable option for the basic design of nonlinear structures with a negative Poisson effect.

This paper argues that Christian education for sustainability should be a spiritual education that fosters the spirituality of contentment, poverty, sharing, and justice through a critical review of the concept of "Sustainable Development" (SD), which emerged to overcome today's climate and ecological crisis. To this end, first of all, the efforts and limitations of international cooperation to overcome the deepening environmental problems will be considered. That is, economic interests have been prior to the environmental issues. When it comes to the 'Green Revolution,' there has been a huge gap between the ideal and the reality, so a sustainable society has become distant. Faced with this situation, Christian theology has been trying to build a new theological paradigm, breaking away from the limits of anthropocentric and afterlife-centered theology based on the dichotomy between the physical and the spiritual. Through such theological reflections, Christian education needs to carry out spiritual education focusing on how to deal with the problem of human greed for the restoration of the created world. In this regard, this paper presents the spirituality of contentment, poverty, sharing, and justice. For developing it, this article suggests deep theological reflection and repentance on human greed, listening to the victim's voice, moderation in consumption, investigation of alternative cases, and decisive action to reveal the truth from the victim's point of view.

β-Ga₂O₃ is a material with a wide band gap of ~4.8 eV and a high breakdown-voltage of 8 MV/cm, and is attracting much attention in the field of power device applications. In addition, compared to representative WBG semiconductor materials such as SiC, GaN and Diamond, it has the advantage of enabling single crystal growth with high growth rate and low manufacturing cost [1-4]. In this study, we succeeded in growing a 10 mm thick β-Ga₂O₃ single crystal doped with 0.3 mol% SnO₂ through the EFG (Edge-defined Film-fed Growth) method using multi-slit structure. The growth direction and growth plane were set to [010]/(010), respectively, and the growth speed was about 12 mm/h. The grown β-Ga₂O₃ single crystal was cut into various crystal planes (010, 001, 100, ${\bar{2}}01$) and surface processed. The processed samples were compared for characteristics according to crystal plane through analysis such as XRD, UV/VIS/NIR/Spec., Mercury Probe, AFM and Etching. This research is expected to contribute to the development of power semiconductor technology in high-voltage and high-temperature applications, and selecting a substrate with better characteristics will play an important role in improving device performance and reliability.

With the rapid development in network, graphic technology, and digital technology, content industry is emerging as an important industry for new cultural development and economic development. The development in digital content technology has remarkably expanded the generation and distribution of contents, thereby creating new value and extending into a large distribution market. However, the ease of distribution and duplication, which characterizes digital technology, has increased the circulation of illegal contents due to illegal copying, theft, and alteration. The damage caused by this illegal content is severe. Currently, a copyright protection system targeting online sites is available. By contrast, no system has been established for offline companies that sell offline genuine content, which compete with online companies. The demand for content of overseas tourists is increasing due to the Korean wave craze. Nevertheless, many offline content providers have lost competitiveness due to illegal content distribution with online companies. In this study, we analyzed the case and status of similar copyright certification systems in Korea and overseas through previous research and studied a system to certify the offline genuine contents business. In addition to the case analysis, we focused on interviews obtained through in-depth interviews with the copyright stakeholders. We also developed a certification framework by establishing the certification domain, certification direction, and incentive of the certification system for offline businesses with genuine content. Selected certification direction is ethical, open, inward, store, and rigid (post evaluation). This study aimed to increase awareness among consumers about the use of genuine content and establish a transparent trading order in a healthy content market.
