In regard to modular systems, new methods, as well as middle and high-story unit design ideas, are currently being studied. These studies need to focus on the enhanced stiffness and seismic performance of these connections, and see that the development of fully restrained moment connections can improve the seismic performance. For this reason, this study evaluates the performance of the connections of the ceiling bracket-typed modular system through repeated loading tests and analyses. In order to compare them with these modular units, new unit specimens with the bracket connection being different from that of the traditional modular unit specimens were designed, and the results of repeated loading tests were analyzed. In the traditional units, the structural performances of both welding connection and bolt connection were evaluated. In regard to the testing results, the initial stiffness of the hysteresis curve was compared with the theoretical initial stiffness, and the features of all specimens were also analyzed with regard to the maximum moment. In addition, the test results were examined with regard to the connection flexural strength of the steel special moment frame specified under the construction criteria KBC2016. The connections, which were proposed in the test results, were found to be fully restrained moment connections for designing strong column-weak beams and meeting the requirements of seismic performance of special moment frames.

The purpose of this study is to develop scientist vignettes and to explore their effects to change students' perceptions of scientists, scientific attitudes, and the nature of science. The scientist vignettes developed in this study include research cases on seven scientists, including British zoologist Jane Goodall. Each vignette consists of 4 to 6 pages in consideration of the reading level of elementary school students, and contains illustrations describing the main contents of the text. In addition, scientist vignettes contain descriptions on terms and text boxes explaining the higher concepts, and each vignette contains questions that students can think deeply based on the story of the scientist. To verify the educational effectiveness of scientist vignettes, we investigated changes in their perceptions of scientists, scientific attitudes, and the nature of science in 564 elementary school students. We conducted group interviews with four elementary school teachers. As a result of conducting pre-test and post-test using a narrative questionnaire consisting of 6 questions, students became more sophisticated in the understanding of the science and the characteristics of scientists after experiencing scientist vignettes and their understanding the nature of science changed into a more modern epistemological perspective. Also, in a group interview with teachers, teachers assessed that scientist vignettes would positively affect the understanding of science process skills and the nature of science, and forming a scientific attitude, especially in increasing understanding of the nature of science. We discussed ways to effectively utilize scientist vignettes in elementary school science education based on these result.

Korean adoptee narratives have proliferated over the last ten years as adopted Koreans have begun to represent their own experiences of violent dislocation, displacement and loss in various forms of literary and artistic works, including poems, autobiographical works, novels, documentaries and films. These narratives by Korean adoptees have intervened in the current diaspora discourse to question further the traditional categories of race, ethnicity, culture and nation by representing the unique experiences of the forced and involuntary migration of adopted Koreans. For a long time, the adoption discourse has been mostly constructed from the perspectives of adoptive parents. Therefore the voice of adoptees as well as that of the birth mothers have not been properly heard or represented in adoption discourse. According to Hosu Kim, the U. S. adoption discourse, feeling pressured to deal with the stigma of the commodification of children, changed from viewing the adoptees as children who had been rescued from poverty and abandonment to considering them as a gift from the birth mothers. With the emergence of the gift rhetoric in transnational adoption, the birth mothers erased from adoption discourse have begun to be acknowledged as one of the central characters in the adoption triad. If Korean adoptees are the "the ghostly children of Korean history," the birth mothers are their "ghostly doubles" who "bear the mark of a repressed national trauma." Somebody's Daughter represents the female experiences of becoming an adopted child and of being a birth mother. In particular, the novel makes a birth mother, the forgotten presence in adoptee narratives, into a central figure in the triangular relationship created by international adoption. The novel historicizes the experiences of a Korean adoptee growing up in America as well as those of a mother who had suffered silently from feelings of unbearable loss, guilt, grief and from unforgettable memories. In addition, narrating the birth mother's story is a way to give humanity back to these forgotten women in Korean adoption history. Revisiting the site of loss both for a mother and a daughter through the novel is an act of collective mourning. The narratives about and by Korean adoptees force Korean intellectuals to reflect seriously upon Korean society and its underlying ideology which prevents a woman from mothering her own baby, and to take an ethical and political stand on this current social and political issue.

The purpose of this research is to analyze the psychological dynamics of the characters in the novel 'vegetarian' of the Han Gang and the relationship patterns in the system by applying object relation theory. 'Vegetarianism' has already been analyzed and reinterpreted in various angles, but if you look at it from the object relationship theory and the systematic perspective, you can understand the inevitable history of the generation through psychological analysis and relation dynamics of the person. First, we will analyze the psychological dynamics of the characters by analyzing the meanings and exploring the meaning with the object relation theory and concept. The psychological analysis and the search process of the characters based on the theory are enough evidence for the counselor to reinterpret the life story of the client in the future clinical scene. In addition, in order to realize ethical but practical clinical education, the field of clinical practice will be extended when analyzing the characters using art. It is suggested that the meaning search through various character analysis needs to be accumulated culturally.

This study was conducted to diagnose the issues of AI ethics in global content and to discuss what kind of discourse is needed to strengthen human identity. To this end, the study selected Netflix original content "The Social Dilemma" for analysis and adopted narrative analysis as the research method. The analysis results confirmed that "Social Dilemma" showed the structure of a traditional current affairs documentary and mainly used experts and statistical data to develop the story. It also reinforced core content claims by enumerating domestic and foreign cases such as the 2021 Myanmar massacre and the spread of fake news. In addition, the relationship between the characters clearly revealed the binary opposition between developers and media companies as well as users and advertisers. For the solution to the problem, strong regulations on businesses and the suspension of social media use were reached. However, "The Social Dilemma" merely pointed out the misuse of AI technology and had a narrative that ignored human identity and social relationships. Such results raise the need for creating contents that emphasize the importance of human sociality, relationships, and learning ability in the age of AI.

This research studies the specific cases of Ryusuke Hamaguchi's re-arrangement of the original novel Net emo Samite mo(2010) by Tomoka Shibasaki to his 2018 film Asako I&II. The study focuses on the difference that has been made between the original novel and the film, which occurred after Ryusuke adapted the novel's "Telling" to the film's "Showing." The presence of the passive protagonist and the repetitions are the elements that have been avoided from the traditional Screenwriting theory for a long. Instead of avoiding it, Ryusuke Hamaguchi inherits these traits of the original novel when re-arranging to his film. Despite the presence of a passive protagonist, Hamaguchi's method of adaption increases the attention of the audience by using the other tools of Hollywood's tradition: the use of goal and want of the protagonist. In addition, Hamaguchi's storytelling strategy captivates both the modern cinema audiences and the classical film audiences by creating a story, which both repetitive structure and normative narrative structure were applied.

Recently, cultural heritages in South Korea gain many interests of restoration and preservation from the government since many of that have been severely damaged during earthquakes. Many previous studies in both terms of experimental and analytical approaches have been done to examine structural behavior and decide appropriate methods of preservation. Being motivated by such researches, this research aims to investigate a religious stone pagoda dated back to the Goryeo Dynasty in Korea. The structure consists of a granite stone foundation and baked bricks, which resembles the shape of traditional pagodas. In order to examine the structural behavior of the pagoda, an analytical model is implemented using ANSYS, a comprehensive engineering simulation platform. For the time history analysis of the pagoda, several earthquake excitations are chosen and input to simulation modeling. Seismic response of the tower such as time domain, natural frequency, modal shapes and peak acceleration measured at each layer are presented and discussed. In addition, the amplification ratio of the tower is calculated from the accelerations of each layer to determine tower stability in accordance with Korean seismic design guide. The determination and evaluation of status and response of the brick tower by simulation analysis play an important role in the preservation of history as well as valuable architectural heritages in South Korea.

Analytical models were developed and seismic behaviors were analyzed for a three-story stone pagoda at the Cheollyongsa temple site, which was damaged by the Gyeongju earthquake of 2016. Both finite and discrete element modeling were used and the analysis results were compared to the actual earthquake damage. Vulnerable parts of stone pagoda structure were identified and their seismic behaviors via sliding, rocking, and risk analyses were verified. In finite and discrete element analyses, the 3F main body stone was displaced uniaxially by 60 and 80 mm, respectively, similar to the actual displacement of 90 mm resulting from the earthquake. Considering various input conditions such as uniaxial excitation and soil-structure interaction, as well as seismic components and the distance from the epicenter, both models yielded reasonable and applicable results. The Gyeongju earthquake exhibited extreme short-period characteristics; thus, short-period structures such as stone pagodas were seriously damaged. In addition, we found that sliding occurred in the upper parts because the vertical load was low, but rocking predominated in the lower parts because most structural members were slender. The third-floor main body and roof stones were particularly vulnerable because some damage occurred when the sliding and rocking limits were exceeded. Risk analysis revealed that the probability of collapse was minimal at 0.1 g, but exceeded 80% at above 0.3 g. The collapse risks at an earthquake peak ground acceleration of 0.154 g at the immediate occupancy, life safety, and collapse prevention levels were 90%, 52%, and 6% respectively. When the actual damage was compared with the risk analysis, the stone pagoda retained earthquake-resistant performance at the life safety level.

Evaluating the current condition of existing structures is of primary importance for economic and safety reasons. This can be addressed by Structural System Identification (SSI). A reliable static SSI depends on well-designed sensor configuration and loading cases, as well as efficient parameter estimation algorithms. Static SSI by the Measurement Error-Minimizing Observability Method (MEMOM) is a model-based deterministic static SSI method that could estimate structural parameters from static responses. In the current state of the art, this method is only applicable when structures are subjected to one loading case. This might lead to lack of information in some local regions of the structure (such as the null curvatures zones). To address this issue, the SSI by MEMOM using multiple loading cases is proposed in this work. Observability equations obtained from different loading cases are concatenated simultaneously and an optimization procedure is introduced to obtain the estimations by minimizing the discrepancy between the predicted response and the measured one. In addition, a Genetic-Algorithm (GA)-based Optimal Sensor Placement (OSP) method is proposed to tackle the OSP problem under multiple static loading cases for the very first time. In this approach, the Fisher Information Matrix (FIM)'s determinant is used as the metric of the goodness of sensor configurations. The numerical examples of a 3-span continuous bridge and a 13-story frame, are analyzed to validate the applicability of the extended SSI by MEMOM and the GA-based OSP method.

This study analyzed the placement and interactivity of the immersive performance . In the sense of place, it was analyzed that first, walked and followed the living spaces and streets of the victims of the Sewol ferry, and second, through this, the participants induce a transfer experience to become the main character of the performance. In terms of interactivity, participants were able to carry out various forms of participation, and as a result, they analyzed that they had relieved debt consciousness or exerted healing effects. In addition, it was confirmed that they pursued solidarity and sympathy by focusing more on the city 'Ansan' rather than the story of the Sewol ferry. Through these results, it can be seen that has many social functions, a variety of art forms, and is differentiated from other immersive performances. So, it is necessary to consider the continuous holding.
