This research intends to look into how mathematically gifted 6th graders (age12) who have not learned conditional probability before solve conditional probability problems. In this research, 9 conditional probability problems were given to 3 gifted students, and their problem solving approaches were analysed through the observation of their problem solving processes and interviews. The approaches the gifted students made in solving conditional probability problems were categorized, and characteristics revealed in their approaches were analysed. As a result of this research, the gifted students' problem solving approaches were classified into three categories and it was confirmed that their approaches depend on the context included in the problem.

The purpose of this research was to explore the phenomenon of object relations with musical instruments as experienced by professional Samulnori musicians. The researcher conducted in-depth individual interviews with five Samulnori players who also completed questionnaires with open-ended questions. The data were analyzed using Giorgi(2004)'s phenomenological methodology. The results offered 121 semantic units, seven subcategories, and three main categories. The three main categories were transitional object, object of expression and recognition of internal desires, and object for recognition of others and communication. These results suggest that the ensemble format of Samulnori promotes the development of the musician's object relationship and can externalize the player's internalized representational system and interaction method. This study is significant in that it reveals the endopsychic functional relationship between a musician and their instrument and provides the basis for the use of Samulnori instruments in music therapy.

The purpose of this study was to examine the meaning and essence of the life of elderly men living alone in public rental housing. Among the phenomenological study methods, the present study used the analysis method proposed by Giorgi(2009). The study participants included 10 elderly men living alone in public rental housing who were recruited through network sampling. The research data were collected through in-depth interviews conducted twice for each person. The results showed that living alone as an elderly man is likened to standing against cold wind out in the wilderness of the world, with living alone deemed a power game between life and death. For the participants, public rental housing is a fence that separates them from the world-the final station of a wandering life. For common people, public rental housing is a stable fence, but for the participants, it is the location of a double-edged solitary life out in the wilderness where the instincts for survival and death play a tug of war. Based on the study findings, the researcher discussed and provided suggestions for psychological housing stability, the disparagement of the elderly in mass media, and countermeasures against psychological isolation.

The purpose of this research is to study how an elderly male lives after the experience of bereavement, and to understand the experience's essence. The researcher picked 3 elderly men living alone after separation by death as test subjects and gathered information through in-depth interviews. The analysis of the information was done based on the three-dimensional space of narrative presented by Clandinin and Connely(2000), and it restructures the common experience under five meanings. The mutual themes of 'It's the life of a sinner, but not wanting to be seen as a widower to others', 'The fear for death, and the preparation for after death', 'Trying to stay alive for the children', 'Entering the world to find meaning in a gloomy life', and 'A lone goose lost in search of social warmth' came from the research results. The essence of the experience studied with the mutual themes as basis came out to be 'A struggle to take flight again after one broken wing'. This research has a major significance in that elderly males' experience of bereavement was studied in the dimension of time continuity, and that individual social interactions that are made by elderly males to continue their lives after the experience of bereavement were studied.

This study deals with the anxieties that originated from specific student questions. Through the analysis of the textbooks, we confirmed that the question was a sufficiently plausible question. Third interviews were also held with three high school students. Through the interviews, we analyzed students' expressions about the new correspondence relationship that the two correspondence relations are linked. In the determination of the composite function and the determination of the inverse function existence, We have observed a case of how the worries about domain are being reconstructed from students into meaningful mathematical knowledge. Through this, we confirmed that the question will be confusing to students in the field. In this study, we observed the transfer of domain in relation to student domain in composite function. In particular, a present study revealed that the students involved in the interview were influenced by this domain transfer phenomenon in determining whether the task given in the interview was a function. This was the same in determining the existence of a inverse function. The examples presented in this study are limited to specific cases in limited circumstances. Therefore, it can not be applied directly to teaching and learning situations. However, it is expected that this study will provide other researchers with insight into function learning related research.

This study examined the sub - dimensions of mobile food platform service characteristics and verified how they affect the usability, usability and re - use intention. The data collection is from February 11, 2019 to February 28, 2019. The researcher visited the food service company and presented the questionnaire by direct interview. The results of the analysis are summarized as follows. First, the ubiquitous connectivity and interactivity of the mobile eater platform service have a significant effect on ease of use, but the situational awareness has no significant effect. Second, ubiquitous connectivity, situational awareness, and interactivity have a significant effect on usability, and ease of use has a significant effect on usability. Third, ubiquitous connectivity has a significant effect on re - use intention, and situational awareness and interactivity have a significant effect on re - use intention. Fourth, ease of use has no significant effect on re-use intention, but usefulness has a significant effect on re-use intention.

In this study, we focused on the experience of interpersonal trauma among university students majoring in counseling psychology to understand the meaning of the trauma they experienced, and analyzed the process of their growth as counselors. To that end, we conducted a survey on interpersonal trauma and post-traumatic growth, and interviewed final six students in a face-to-face interview, and analyzed the collected data using the method of qualitative case study. As a result, the trauma and subsequent growth experience have been categorized into 38 semantic units, 15 subcategories and 5 categories, including 'Times of pain', 'A life of dealing with complex emotions alone', 'An experience of understanding and being understood', 'Attempts to change and new meanings' and 'Worries and expectations of growth as a counselor'. The results of this study are meaningful in providing basic information and educational materials needed for the intervention of students majoring in counseling psychology who have experienced trauma.

This study aims to identify what kind of epistemological resources were activated in unproductive and productive practice by students participating in scientific argumentation, and to explore which contexts result in changes in argumentative practice. We collected transcriptions of participants' argumentative lessons and interview, participants' work sheets, and researchers' field notes. The analysis revealed that the focus group activated different kinds of epistemological resources depending on their practice; propagated, belief, and accumulation in unproductive practice and constructed, understanding, accumulation, formation and rebuttal in productive practice. We found two contextual cues that led to these changes; unfamiliar form of argumentative task was provided and emotional, epistemic, and conceptual support of the epistemic authority. This work can be provided as additional case studies to analyze changes in practice according to learner context-dependent epistemology, and we expect to contribute to discussions of productive epistemology and stabilization for students' authentic science engagement.

This study was started on the premise that it was necessary to analyze the users and their needs of the national bibliography in order to develop a new national bibliographic service strategy. Based on this premise, the main purpose of this study is to analyze the users' situation and needs on the Korean national bibliography, and to establish a new service strategy that reflects the user's perspective. In addition, it has a secondary purpose to find the basis for justifying the value and persistence of the national bibliography from user. To this end, first, identified the main user groups of national bibliography through literature and case studies. The data were collected from a interview with 51 people from 4 groups (librarian, researcher, publishing distributor, end user) that are expected to use national bibliography. As a result of the interview, it was possible to confirm very low awareness and utilization of the national bibliography. In addition, the interview results revealed that there is a need for improvement in terms of the method of operating the national bibliography, the content to be provided, and service.

This study aims to identify the student assessment competency of the three elementary science teachers and investigate strategic measures to improve them. The study progressed as a qualitative case study method. A self-awareness checklist and in-depth interviews were conducted to collect data. The data analysis was reviewed and agreed upon by two process-focused assessment-leading teachers and two elementary science education experts. Consequently, the level of self-awareness of student assessment competency of the three participants was relatively high. However, the scale average of the feedback area was the lowest on average. The student assessment competency of the participants showed different levels and characteristics. Additionally, some inconsistencies between perception and practice were found. Strategic support and education are needed to enhance elementary science teachers' student assessment competency, and the development of self-diagnosis tools should proceed.
