  • STATs are proteins with a dual function: signal transducers in the cytoplasm and transcriptional activators in the nucleus. Among the six known major STATs (STAT1-6), STAT3 has been implicated in the widest range of signaling pathways that regulate cell growth and differentiation. As a part of our on-going investigation on the pleiotropic functions of STAT proteins, we examined the role of STAT3 as a molecular adaptor that links diverse cell growth signaling pathways. We observed that STAT3 can be specifically activated by multiple cytokines, such as IL-3, in transformed fibroblasts and IL-4 or IFN-$\gamma$ in primary immune cells, respectively. The selective activation of STAT3 in H-ras-transformed NIH3T3 cells is associated with an increased expression of phosphoserioe STAT3 in these cells, compared to the parental cells. Notably phosphoresine-STAT3 interacts with oncogenic ras, shown by immunoprecipitation and Western blots. The results suggest the role of STAT3 in rasinduced cellular transformation as a molecular adaptor linking the Jak/STAT and Ras/MAPK pathways. In primary immune cells, IL-4 and IFN-$\gamma$ each induced (in addition to the characteristic STAT6 and STAT1 homodimers) the formation of STAT3-containing complexes that bind to GAS probes, which correspond to the $Fe{\varepsilon}$ Rll and $Fe{\gamma}$ RI promoter sequences, respectively. Since IL-4 and IFN-$\gamma$ are known to counter-regulate the expression of these genes, the ability of STAT3 to form heterodimeric complexes with STAT6 or STAT1 implies its role in the fine-tuned control of genes that are regulated by IL-4 and IFN-$\gamma$.

  • This study, using Fractal theory, aims to examine the meaning in the aspect of urban spatial structure by reflecting the characteristics of elements organizing the urban space and at the same time measuring the urban form quantitatively. By calculating Fractal Dimension to Cheongju as a target, it conducted comparison and analysis by dividing building and road which are internal element of a space into the whole city and urbanized area to compare and analyze validity of the theory application and the inside of an actual urban space. For the method of an analysis, it calculated Fractal Dimension by linking a digital map including the property of building and road with GIS program and using box counting. An analysis result showed that the result value of Fractal Dimension by structure and road is all high and similar. It drew a similar result value from the whole Cheongju and the urbanized area as well, but commercial and industrial area showed low result value from the partial viewpoint. However, it is correct to regard these spaces as one space because they are intimately connected with a residential area. From the general viewpoint, it could be said that Cheongju's Fractal Dimension grows in the context of a urbanized area.

Therefore, the authors of this paper studied the physical deformations and characteristics of flexible displays by user manipulation through literature and case studies. This research suggests the following guidelines for a flexible display interface design for the user experience. First, it must be designed to provide the functionality that users need in a variety of display environments. Second, in using the interface, external factors should be removed from the viewing angle of multi-users. Third, all possible user actions should be considered on flexible displays other than touch and contact. Fourth, flexible design of flexible display requires changing interface design for user experience.

  • The purpose of this study was to survey the secondary science teachers' viewpoints of basic particles conceptions addressed in science course. The first content of this study was to analyze the secondary science teachers conceptions related to basic particles founded on scientific history viewpoints. The second content was to investigate their understanding of relations between atom, element, and molecule concepts. The third content was to search the factors influenced on basic particles conceptions of science teachers. For this study, 96 secondary science teachers were selected. The data of this study were collected through a questionnaire developed for this study and were analysed using the method of constant comparative analysis. The results showed that their viewpoints towards basic particles were similar to each other regardless of their majors and their conceptions belonged to the past viewpoints. The teachers lacked linking understand among basic particles conceptions because they applied different viewpoints on different problems. Most of the teachers were influenced on science textbooks, guidebooks for teachers, and reference books to form confusing viewpoints of basic particles.

  • Religion is the symbolic form and action, linking the ultimate condition of life with human beings. Religious idea grasps the world through symbols and gives birth to the action through symbols. This research put its purpose in elucidating the effect of religion on the costume and its mechanism. It's focus is centered on Buddhism, Hinduism, and Islam which are among the world high religions. Part of this research also examines the mechanism in which several composing factors are expressed with rituals and manifested with costumes, this process was diagrammatized and suggested. The composing factors of religion such as belief system, experiences, community, and rituals are closely related. Ritual especially, is the symbolic action, practice, and the way of rescue, expressing religious meaning. Religious rituals such as imitative rituals, positive or negative rituals, sacrificial ritual, and rites of passage have been expressed with religious music or figurative art such as costume, construction, and art as well as religious ritual like ancestral rites. Religion has had a great effect on the overall culture including costume as a belief system by lightening the meaning of life and suggesting the solutions to the human problems such as anxiety or conflict.

  • Dispersion polymerization of methyl acrylate, ethyl acrylate, butyl acrylate, and glycidyl methacrylate were performed in supercritical $CO_2$ at $80\;^{\circ}C$ and 346 bar. Glycidyl methacrylate linked poly(dimethylsiloxane) (GMS-PDMS) surfactant, which was prepared by linking glycidyl methacrylate to monoglycidyl ether terminated PDMS with amino-propyltriethoxysilane, was used as surfactant for the dispersion polymerization in $CO_2$. The yield of the poly(alkyl acrylate) polymers, synthesized in $CO_2$ medium, decreased as the alkyl tail of the acrylate monomers increased. Poly(glycidyl methacrylate) and poly(methyl acrylate) were produced in bead form whereas poly(ethyl acrylate) and poly(butyl acrylate) were viscous liquid. The poly(glycidyl methacrylate) particles had a number average diameter of 2.45 ${\mu}m$ and monodisperse distribution. The poly(methyl acrylate) had a number average diameter of 0.52 ${\mu}m$ and the particle size distribution was bimodal. The glass transition temperatures ($T_g$) of the poly(glycidyl methacrylate) and the poly(alkyl acrylate) products were 4~9 K higher than the $T_g$ of the corresponding acrylate polymers synthesized in conventional processes.

  • Technical documents in the construction field are changing from paper documents to electronic ones. As a result, the industry witnesses a trend of using portable electronic devices in searching or retrieving necessary information such as relevant regulations. Despite the improvement in the accessibility to general technical documents, a limitation is still found in accessing the electronic documents on the regulations. We see the barrier for field engineers to enhance their technical knowledge. One of major barriers is that videos, animations, and virtual reality information to enhance the visual understanding of technical content related to regulations are not linked. It is the interactive electronic technical manual (IETM) that can address such issues. The IETM is an electronic document system that enables real-time information acquisition while operating in the form of conversations with users by linking multimedia functions to document types such as specifications and guidelines. This study establishes a model of the IETM that can be operated in the planning stage of a construction project. The study also verifies its usability with a hypothetical case study. This study aims to improve the usability of the IETM in the construction project by analyzing the application effect of the IETM using the AHP technique.

  • In this article, I focused on the identity of the Japanese magician, Tenkatsu(天勝), who appeared in Exhibition of Joseon, 1915, and the social gaze and reverberation of them. I would like to see how Tenkatsu group appeared, how it was active, and how it was utilized. Because It was a big stimulus for traditional performing artists. 'Ma-sul' was a new word, taking the place of 'Hwan-sul(幻術)' or 'Hwan-hee'(幻?) for a term of english 'Magic'. In the various articles published during the Japanese colonial period, we can find the performers of the contemporary magic and the Korean artists who tried to make them nationalized. In the mid-1920s, a magician of Korean origin appeared. Kim Mun-phil(김문필), Park Chang-sun(박창순), Kim Wan-shil(김완실) were them. They had experience of studying abroad, such as Russia, and were also helped by religion, the Chondo-kyo. They attracted popularity while touring around the country. Incidents of social problems often arise by linking magic to a form of fraud, though. But the appearance of a Korean magician confirms the existence of a performer who actively engages in new performances.

  • Digital transformation, which is accelerating in each area of society due to the COVID-19 pandemic, is also having a profound effect on Christian education. A representative example of digital transformation is the emergence of a digital world called the metaverse. This study understands the metaverse as an expanded space for Christian education and explores digital storytelling as a method for faith formation. It is argued that the characteristics of digital storytelling through metaverse spaces are characterized by interactivity, agency, audiovisuality, sociality, and openness, and that modification through Christian educational frames is necessary in order for this approach to be appropriated to Christian educational practice. To this end, this study examines Anne Wimberly's story-linking approach, and Mary Hess' approach on digital storytelling, which is understood as a way of faith formation for the liberation and Christian vocation through storytelling in a digital space, focusing on authority, authenticity, and agency. It is argued that Christian education on the Metaverse should be a place for change in the Christian life and formation of vocation, and a space where participants' active responses to God's grace be practiced in a digital space in a reciprocal way. This means that learners are encouraged to participate in expressive and relational education that is practiced in the form of play and creation, responding to God's initiative in the metaverse. This study argues that for digital storytelling through the metaverse to become a process of faith formation, it is necessary to connect stories of participants with the story of God's Kingdom in the expanded digital world, aim for a reciprocal space through hospitality and listening, and promote immersive participation and holistic reflection.
