Purpose of the Study : This study aims to propose alternative church education methodologies utilizing generative AI in the age of artificial intelligence. To achieve this, a project-based church education program using generative AI was developed and applied for a weekend retreat at Y Church's youth ministry located in Seoul. The study involved 18 youth participants and 5 teachers, and was conducted over two weekends, from February 17-18 and February 24-25, 2024, in a non-residential format. Contents and Method : The research methods included developing and applying the generative AI-based Bible education program, then assessing program satisfaction, effectiveness, and the internalization of faith through surveys and interviews with students, teachers, and the overseeing pastor. Satisfaction was measured using pre- and post-program questionnaires, while effectiveness was evaluated through pre- and post-program mind map assessments. To measure the internalization of faith, reflection journals and interviews were conducted. Conlusion : Analysis of the data from the 16 participants who attended both pre- and post-assessments revealed satisfaction with various aspects, including preferences for educational content, the value of educational activities, effort in participating in activities, perceived competence in the activities, preferences for the educators, preferences for the institution, and willingness to recommend the program to peers. The average satisfaction score increased from 11.92 before the program to 27.25 after, showing a significant increase of 15.33, which is statistically significant at the .05 level. Although the changes in faith maturity were not explicitly detailed, a slight change in faith through practical learning was observed. Additionally, the cognitive aspects of the learning content showed longer-lasting effects compared to typical retreats.

In design studies, there has been extensive prior research on accident and disaster prevention, but it mainly focuses on visualization methods to improve visibility. Most accidents and disasters are caused by human factors. However, there is little design research that considers human characteristics that manifest in dangerous situations. This study aims to identify the concepts and characteristics of safety information design that reflects human traits. It examines the concepts of risk and safety from a social science perspective and looks into human visual information processing from a cognitive neuroscience perspective. Additionally, it explores the relationship between human information processing and accident rates in dangerous situations from a psychological perspective. Based on these analyses, the study distinguishes between conventional information design and safety information design, ultimately identifying the features of safety information design that incorporates human traits. The key findings are as follows: First, information should be presented considering the human tendency to suspend rational judgment in dangerous situations. Second, appropriately dispersing or concentrating attention according to the level of risk can serve as an opportunity to minimize harm. Third, it was found that sensory and perceptual characteristics should be given top priority in the field of risk and safety information design. Through these findings, the study concludes that a design approach that reflects human traits in safety information design can ultimately be a key indicator for improving safety levels.

Three similarities (i.e., geometrical similarity, kinematic similarity and dynamic similarity) between a prototype and model must be satisfied to perform an experiment for a floating offshore wind turbine (FOWT). For dynamic similarity, most of the model tests in ocean engineering basins are performed based on the Froude number, so the scale effect for the wind turbine of an FOWT occurs by different Reynolds numbers between the prototype and model. In this study, various model test techniques for overcoming the scale effect of the wind turbine part of the FOWT are investigated. Firstly, model test techniques using simple approaches are reviewed, and the advantages and disadvantages of the simple approaches are summarized. Secondly, the model test techniques in recent projects that apply improved approaches are introduced including advantages and disadvantages. Finally, new approaches applying digitalization are reviewed, and the characteristics of the new approaches are introduced.

This study analyzed the effectiveness of lessons using metaverses and generative AI for pre-religious teachers through a qualitative case study. Eight third-year students in the Department of Christian Education at A University in Gyeonggi-do, South Korea, designed and conducted a project-based learning (PBL)-based class on 'e-Bible study material design' using metaverses and generative AI. The students analyzed the church school site, identified practical problems, and developed Bible study materials using generative AI to solve the problems. After storyboarding the Bible, they used generative AI to generate pictures, voices, and background music and implemented them into a digital Bible picture storybook and metaverse environment. To analyze the results of the study, we conducted an in-depth analysis of learners' reflection journals and interviews, and found that learning with generative AI and metaverse environments not only increased interest and immersion, but also showed positive changes in their ability to utilize generative AI and metaverse and their awareness of the need for AI convergence education. In addition, we confirmed the possibility of extending the learning experience beyond the classroom into everyday life through self-directed learning and collaborative problem-solving processes. However, the generalizability of the results is limited due to the limited time and number of participants in this study, but it suggests the possibility of education using generative AI and metaverses as an alternative education method in the era of great transformation.

The purpose of this study is to analyze physical activities in 'Teachers' Guidance Books for the Nuri Curriculum of 4-year-old children' through simulated instruction of pre-service teachers and, through this, to help them better perform physical activities in their field education for early-aged. The subjects of the study were 30 sophomore students in the early-aged children's Education Department in their 2ndsemester of K University located in Gyeonggi-province. For the analysis of physical activities in 'Teachers' Guidance Books for Nuri Curriculum of 4-year-old children', a qualitative study was conducted and data were collected through informal interviews, reflective journals of pre-service teachers and 30 sessions of education assessment sports. The results of the analysis on the physical activities in 'Teachers' Guidance Books for Nuri Curriculum of 4-year-old children' are as follows; first, preliminary teachers of early-aged children understood the major goal of physical activities in 'Teachers' Guidance Books for Nuri Curriculum of 4-year-old children' as 'expressing.' Second, the teachers thought careful analysis is required on media such as 'video, illustration books, sounds, picture materials' presented together with physical activities in 'Teachers' Guidance Books for Nuri Curriculum of 4-year-old children.' Third, teachers pointed out 'activities that were difficult to understand for pre-service early childhood teachers' and 'improperly presented activities different from the title' as errors and problems in the performance of the Nuri Curriculum. Fourth, as for 'points to make improvement on', pre-service early childhood teachers' requested basic physical activities before the actual activities, the provision of proper actual materials, the necessity of active demonstrations of teachers and making a regulation for the situation of physical activities by early-aged children and teachers together. The results of the study illustrate that deep contemplation and judgment is required of the teachers before conducting physical activities of the Nuri Curriculum.

This study inquires how human interest news on society section of newspapers had been modulated as multi-layered political narratives that would consistently have Koreans consider, realize and question on colonial situation as well as ethnic identity. Under totalitarian censorship of the colonial government, newspapers could not publish reports on political issues and current affairs, so society page of human interest such as crime, accident, conflict, disaster, and many kinds of sufferings of peoples to death would take great public attention and consequently be considered as a substitute of political section. Society page had enjoyed its influence on formation of public opinion of the colonized ethnic society and had maintained cultural-nationalist position ever since the founding of newspaper in mother-tongue in 1920. In colonial context, there is nothing non-political to the lives of the colonized, social facts would be necessary and happen to be modulated into a narrative that could trigger nationalist sentiment. For this end, news reporting of society section usually concentrated on aspects of 'Les Mis${\acute{e}}$rqbles', dramatic quality, and psychological factors in detail. Narrative style of news reporting got used to modulate factual informations with a proper taste of exaggeration, emotional expression, and commercial touch of exciting words. Even in a case of death by drug abuse, news was written to indicate what made him/her drive to miserable death on street, that is, what is de facto reason of all of social problems like as migration, hunger, leaving home, crime, suicide, violence, gambling, love affairs to death, adultery, and even opium habit. Those social problems and personal sufferings appeared up on newspaper 3rd page at daily base. Readers could acknowledge and identify what the real matter that should be resolved and then blame colonialism, capitalism, and militarism for those social problems. Journalists put values on inciting the colonized to realize the national and ethnic situation and feel sympathy for their people tied up by a common destiny. In this terms, news on society section of newspaper under Colonial Occupation were encoded as narratives of politically layered text and then decoded as intriguing sentiments against colonial dominance. I argue that society page of newspaper of colonial period engaged in a sort of cultural politics of sentiment and emotion which is a private area outside of imperial sight.

The research evaluated the effects of the improvements in scientific inquiry for elementary school students and focused on the development and application of the explicit and reflective learning strategy through observation and classification. The explicit and reflective learning strategy was modified and completed with the review of the experts after the development of the draft based on the theoretical approach. The students were evaluated for their academic achievements in scientific inquiry skills before and after taking the course. The results were as follows: First, the steps of the developed learning strategy (1) to motivate, (2) to explore reflectively, (3) to guide explicitly, (4) to inquire explicitly, and (5) to verify reflectively were set to reflect the verification. Second, the results of applying the developed model to the lessons based on the quantitative analysis was effective for observation and classification skills in the quest for improved performance of the whole (the sum of observation and classification, inquiry skills) and the observed features, but there was no effect on classification. Also, the lessons applied the developed teaching strategy and showed effectiveness in improving academic achievement. Particularly in analyzing the relationship between the academic achievement and exploration capabilities, in order to improve academic achievement, the importance of improving inquiry skills was found. Third, the qualitative analysis of teaching and learning strategy developed by applying the lessons of this teacher guide and small group activities through the explicit and reflective observation and classification of the student learning activities showed the significant improvement of ability of the scientific inquiry skills. In addition to the improvement in the abilities of the classification showed after the formation of the most basic observation skills of the scientific inquiry.

The Korean Society for Clinical Laboratory Science publishes the Korean Journal of Clinical Laboratory Science (KJCLS) as the official journal for the Korean Association of Medical Technologists. This year, 2017, marks the 50th anniversary of KJCLS. The original name was "the Korean Journal of Medical Technologists" (Volume 1, 1967~Volume 26, 1994), which was replaced with the "Korean Journal of the Clinical Laboratory Science" (Volume 27, 1995~Volume 35, 2003) and "the Korean Journal of Clinical Laboratory Science" (Volume 26, 2004~Present). The purpose of this study was to provide a framework for further development of KJCLS. In 1998, the National Research Foundation of Korea began the journal assessment service. The major domestic databases are KCI, KOFST, and KAMJE; the major international databases are SCI Index; SCI Core, SCI-Extended), SCOPUS, MEDLINE, and PUBMED. KJCLS has been registered with KCI of the National Research Foundation of Korea since 2014. More than 1,300 articles have been published, which all have made tremendous contributions to the field. To index KJCLS in the journal databases, we measured the value to understand the vocational level and social position. KJCLS is faced with a great challenge; immense effort will be needed to accomplish the original goal of KJCLS to become an internationally recognized journal. Ultimately, the goal of the Korean Society for Clinical Laboratory Science and the Korean Association of Medical Technologists should be to register KJCLS in databases such as KCI and SCOPUS.

The purpose of this study was to investigate the change of teacher-student interaction in a beginner secondary science teachers' class through collaborative mentoring program. Three experienced science teachers as mentors and three beginner science teachers as mentees were participated in this study. Mentors have been teaching science secondary school for more than 13 years with specialty in science education, and mentees have been teaching less than three years in secondary schools. They were matched one-toone on grounded characteristics that were revealed from pre-interview. Data collection consisted of lesson plans of mentees' classes, videotaped lessons of mentees, consultation meetings between mentors and mentees, and interviews with mentees as well as mentors. The consultation meetings and interviews were audiotaped and then transcribed with the videotaped lessons. To examine the change in teacher-student interactions, the lesson observed after four sessions of mentoring was compared to the lesson before mentoring on the basis of the analytical framework that was developed based on the interpretative approach. The analytical framework addresses the four aspects of teacher-student interaction, which include beginner of interaction (initiation), the types of the question, the student response and the feedback. After four sessions of collaborative mentoring, the beginner science teacher's classroom interactions were initiated by students more often. Teachers' questions increasingly turned into thought-provoking queries that required higherorder thinking. The students responded in the form of statements instead of asking question more frequently. Also, teachers provided more delayed feedback than immediate feedback. These changes of interaction patterns showed that students took a leading role in classroom interaction and they were encouraged to think. From this result, we argue that the beginner science teachers developed the ability to make students think and to support them in coming to an understanding of knowledge through a collaborative mentoring program.

This research is a comparative analysis of article titles in the beginning period of Korean newspapers. The Independent, The Korea Daily News and The Dong-A Ilbo were chosen for this research because each was the representative newspaper of 1890s, 1900s and $1920s{\sim}1930s$ respectively. In result, The Independent's article titles had been appeared on nearly 2 years after its first issue. Before the appearance of titles, The Independent had divided articles only with section names. In 1900s, The Korean Daily News's article titles was longer than those of The independent. And in 1910, the titles of The Korean Daily News had been placed on separated line to divide articles clearly. But during these period, typographical development of titles was not shown and the width of title was remained in one column. This means, the function of title in these periods was not to represent the value of article but only to divide the articles. In 1920s, The Dong-A Ilbo had used big size types and multi-column edit and those changes enabled newspaper to introduce the concept of layout. During the decade of 1930s, The Dong-A Ilbo's titles had occupied more space on newspaper than earlier period. This could be explained from the perspective of sensationalism of commercial newspaper and a tendency of putting more weight on titles. On the dimension of expression, proportions of subjective titles in The Independent, The Korea Daily News were 44.4% and 28.3% each, but the subjective titles of The Dong-A Ilbo in 1920's were only 4.2%. This decrease can be explained by the settlement of objective journalism in Korean newspapers during $1920s{\sim}1930s$.
