This study inquired following research questions by a narrative research method : What was the job of an engineer in mechanical design field? How did he fulfill his job-related learning in his workplace? What were the context and the characteristic of the job-related learning in the workplace? And some implications of the job-related learning on engineering education were discussed. We identified that the research participant's career as a mechanical engineer has developed through three stages. At first, he engaged on conceptual design of a semi-conductor test machine through self-initiated learning from basic to whole system of the machine. At second stage, he leaded a design group for the concrete design of a ball type semi-conductor test machine. In this stage he learned the meaning of cooperation and cooperative learning. At third stage, he initiated to found an entrepreneur company that was specified to design a semi-conductor test machine. He became CEO of the company. He learned the R & D policy making through contacts with global company, visiting exhibition in abroad. Eventually his main task as a mechanical engineer was the problem solving in the process of machine design. He had experienced and learned through his works : project management, independent fulfilling of tasks, functional analysis and reverse engineering, conceptualizing and test, cohesive cooperation, dialogue and discussion, mediation of conflict, human relationship, leadership. The implication of the narrative analysis on engineering education is, proposed, to give the students more chances to experience and to learn such activities.

The purpose of this study was to investigate high school students' conceptions and conceptual types on molecular kinetic theory of gases. Data was collected by a series of semi-structured and in-depth interviews, and has been analyzed. This study showed that the students came to science classes with various prior conceptions of many disciplinary topics. Their conceptual types of their prior knowledge were distinguished as superficial terms-speaking, partial sense-making, and causal sense-making by the degrees of organization and elaboration of conceptual networks. These conceptual types had influence on the ways students understand and think of science, a stability of their conceptions, a tendency to distinguish school science from everyday science, and building a meaning of concept in contexts. It was referred that the students didn't have proper understanding on the nature of scientific knowledge and had been limited their participations as active learners. Therefore, in order for students to experience conceptual change, they must have opportunities of manifesting their own thinking, taking part in discussions, and promoting their motivations and metacognition of knowing and learning science.

The purpose of this study is to understand the meaning and context of adolescents' experiences of repetitive self-injury and to suggest that self-injurious behavior has characteristics of addictive disorder. In-depth interviews were conducted from December 26, 2022 to January 1, 2023 by using a semi-structured questionnaire for six adolescents who are attending outpatient psychiatirc clinic showing repetitive behavior of self-injury. The data were analyzed using Colaizzi's phenomeno-logical method focused on deriving the common attributes of all participants. We classified derived common attributes in the aspect of the diagnostic criteria of DSM-5 addictive disorder. 21 sub-themes and 6 categories were derived by gathering common meanings from 268 semantic units. The six categories of this study were raging pain, a wound that cannot not be revealed, extreme pores being pierced, continuous longing for self-harm, process of moving forward with pain. In the future, there is a need to develop various systematic intervention programs, including effective coping methods to help clinical adolescents' recover from self-injury, and further evaluation and research on them.

In this study, we investigated the middle school students' processes of scientific graph construction from the perspective of the problem solving process. Ten 9th graders participated in this study. They constructed a scientific graph based on pictorial data depicting precipitation reaction. The think-aloud method was used in order to investigate their thinking processes deeply. Their activities were videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that their processes of scientific graph construction could be classified into four types according to the problem solving strategy and the level of representations utilized. Students using the structural strategy succeeded in constructing scientific graph regardless of the level of representation utilized, by analyzing the data and identifying the trend based on the propositional knowledge about the target concept of the graph. Students of random strategy-higher order representation type were able to succeed in constructing scientific graph by systematically analyzing the characteristics of the data using various representations, and considering the meaning of the graph constructed in terms of the scientific context. On the other hand, students of random strategy-lower order representation type failed to construct correct scientific graph by constructing graph in a way of simply connecting points, and checking the processes of graph construction only without considering the scientific context. On the bases of the results, effective methods for improving students' ability to construct scientific graphs are discussed.

In this study, we investigated pre-service science teachers' NOS-PCK by analyzing their NOS lesson planning and demonstration. Four pre-service science teachers participated in the study. They planned and demonstrated NOS lessons in the context of 'Science Inquiry Experiment' developed under the 2015 Revised National Curriculum. Their lessons were observed. All of the teaching-learning materials were collected, and semi-structured interviews were also conducted. The analyses of the result revealed that pre-service teachers mainly referred to the curriculum and textbooks when selecting the NOS learning objectives. However, they felt difficulty because the curriculum and textbooks did not clearly present the NOS to be dealt. Although all of them took explicit approaches, there were not many open and divergent reflective approaches. In addition, they expected that high school students would consider scientific knowledge absolute and would have negative perceptions of NOS lessons. They rarely assessed students' NOS learning, and were reluctant to assess. Finally, most of them had a negative perception that learning NOS is not necessary for all students. On the bases of the results, educational implications for improving the expertise of pre-service science teachers in NOS lessons were discussed.

This thesis is an introduction and critique of the recently released 'Wongyo-Jinjeok(원교진적)'. 'Wongyo-Jinjeok' is the critique of Seokjeong Jeong-Jik Lee (석정 이정직, 1841-1910), a practical scientist and writer during the last years of the Korean Empire, on the calligraphy of Wongyo(원교) Gwang-Sa Lee (이광사, 1705-1777). Even though whether or not Seokjeong follows the flow of Donggukjinche(동국진체) is to be determined by the specialists in this field, this thesis is based on the view that Seokjeong was influenced by Donggukjinche. The academic value of 'Wongyo-Jinjeok' is Seokjeong's preface and epilogue which critiques Wongyo's writing. 'Wongyo-Jinjeok'is a collection of calligraphic specimens from the 18 pieces of Chinese poetry Wongyo had written before and after June 1756 which was the year after he was banished to Booryung. Seokjeong critiqued the writing of Wongyo from the perspective of calligraphic history in the preface and epilogue of 'Wongyo-Jinjeok'. Seokjeong had been positive about Wongyo's taking after the pre-Wangheejee calligraphic style. But at the same time, Seokjeong thought that Wongyo's ability to create was limited by the public morals of that time. Such thought of Seokjeong can be interpreted as an evaluation of Wongyo's calligraphy as having been externally stern but failing to transcend the realm of mastery to the realm of creation.

The ideological context of the Unity of Heaven and Humankind (天人合一) is useful as an approach to understanding the meaning of 'human affairs (人事)' in Daesoon Thought. In Daesoon Thought, the meaning of 'human affairs' occurs within the context of 'the Way of humans (人道)' being based upon 'the Way of Heaven (天道).' However, in Daesoon Thought, the characteristic of 'the Way of Heaven' originates from the Supreme God of the Ninth Heaven (上帝) and His Reordering Works of Heaven and Earth (天地公事). Specifically, this entails the principle of 'what is devised by humanity (謀事在人), is achieved by Heaven (成事在天),' which is inverted to become 'what is devised by Heaven (謀事在天), is achieved by humanity (成事在人).' This is the principle of 'human affairs' that is revealed as the relationship between Humanity and Heaven is newly defined. In addition, the newly changed relationship between Humanity and Heaven is presented as the principle of 'divine beings and human beings mutually guide one another (神人依導).' This principle clearly expresses 'human affairs' in the context of Daesoon Thought. Accordingly, the two directions in which 'human affairs' are completed are expressed as two stages: spiritual enlightenment (靈通) and the Harmonious Union between Divine Beings and Human Beings (神人調化). These two directions in which 'human affairs' pursues 'the Way of Heaven' show a depth beyond just encompassing transcendence and immanence. The relationship between 'the Way of Heaven' and the Supreme God of the Ninth Heaven, in particular, is a useful point for appreciating the how the meaning of 'human affairs' in Daesoon Thought differs from other uses of the term which occur elsewhere.

This paper considers the research content and its historical significance of the Study of Nature conducted by John Ruskin(1819-1900) who had a profound influence on art, architecture, social reformation, and preservation of natural environment in Great Britain. Because Ruskin's Study of Nature would be the key to understand totally the implicative meaning of his various academic trials for integrating a wider contexts among human, culture, and society, without being bound by the rules of conventional disciplines. For Ruskin, 'Nature' is defined as 'a system' governing every aspects of human and non-human beings, formulating certain laws of composition. This system has an ecological quality to form a state of harmony by internal interaction and process. Such organic quality of nature worked as 'a metaphor' in Ruskin's research practices. Therefore, Ruskin's Study of Nature would be the conceptual basis for organizing and connecting its various elements of Ruskin's spiritual world.

The purpose of this study is to investigate the users' expectation and expectation gap about the attributes of smart speaker as an intelligent agent, ie autonomy, sociality, responsiveness, activeness, time continuity, goal orientation. To this end, semi-structured interviews were conducted for smart speaker users and analyzed based on ground theory. Result has shown that people have huge expectation gap about the sociality and human-likeness of smart speakers, due to limitations in technology. The responsiveness of smart speakers was found to have positive expectation gap. For the memory of time-sequential information, there was an ambivalent expectation gap depending on the degree of information sensitivity and presentation method. We also found that there was a low expectation level for autonomous aspects of smart speakers. In addition, proactive aspects were preferred only when appropriate for the context. This study presents implications for designing a way to interact with smart speakers and managing expectations.
