In the school mathematics, the negative numbers have been instructed by means of intuitive models(concrete situation models, number line model, colour counter model), inductive-extrapolation approach, and the formal approach using the inverse operation relations. These instructions on the negative numbers have caused students to have the difficulty in understanding especially why the rules of signs hold. It is due to the fact that those models are complicated, inconsistent, and incomplete. So, students usually should memorize the sign rules. In this study we studied on the didactical phenomenology of the negative numbers as a foundational study for the improvement of teaching negative numbers. First, we analysed the formal nature of the negative numbers and the cognitive obstructions which have showed up in the historic-genetic process of them. Second, we investigated what the middle school students know about the negative numbers and their operations, which they have learned according to the current national curriculum. The results showed that the degree they understand the reasons why the sign rules hold was low Third, we instructed the middle school students about the negative number and its operations using the formal approach as Freudenthal suggest ed. And we investigated whether students understand the formal approach or not. And we analysed the validity of the new teaching method of the negative numbers. The results showed that students didn't understand the formal approach well. And finally we discussed the directions for improving the instruction of the negative numbers on the ground of these didactical phenomenological analysis.

Purpose: The purpose of this study was to explore the meaning and essence of good nursing from the perspective of patients undergoing hemodialysis. Methods: The data were collected through in-depth interviews of five hemodialysis patients who have been dialyzed for one year or longer. The data analysis was conducted using the Giorgi's phenomenological method. Results: The findings included six constituents and 13 sub-constituents. The six constituents were 'prompt and skillful response to mitigate distress', 'careful attention to provide relief', 'individualized education to promote self-management', 'an intimate relationship to regain isolated ego', 'warmhearted support to encourage strength to live in a exhausting life', and 'providing of comfortable environment to maintain stability'. Conclusion: From the perspective of the hemodialysis patients, the concept of good nursing should stem from the integration of nurses' scientific knowledge, expert skills, and moral sensitivity. The finding suggests that strategies to develop nursing interventions for hemodialysis patients will be required on the basis of understanding of their sociocultural contexts and familism.

Purpose: The purpose of this study was to explore the communication experience of intensive care unit (ICU) nurses in the workplace. Methods: The present study utilized a qualitative approach using focus group interview method. A total of three focus groups of 15 ICU nurses from two university hospitals were formed. The conversations during the focus group interviews were recorded and analyzed through Colaizzi's phenomenological method. Results: As a result of analyzing participants' conversation, Five theme clusters were elicited, namely, "one-way communication", "differences in the position of senior and junior nurses", "communication crisis", "beginning of understanding", and "movement toward change" out of 15 themes and 138 significant sentences. Conclusion: ICU nurses report having experienced communication crisis because of the one-way communication of the ICU nursing environment and the hierarchical differences in junior and senior nurses' position. Systematic education and continuous training on communication skills need to be provided to improve interpersonal relationship among nurses and work environment in the ICUs.

Purpose : This study aimed to explore and describe good nursing experiences of patients with cancer. Methods : Data were collected using individual in-depth interviews with 15 males and 8 females who were hospitalized in a Korean cancer hospital. The transcribed script was analyzed using Colaizzi's phenomenological method. Results : As a result, three theme clusters and nine themes were identified. The three theme clusters were as follows: "being kind and expert in every step along the cancer care trajectory," "taking an omnipotent mediator role supporting patients' well-being," and "providing professional care touching patients' mind and body." Three themes were assigned to each cluster to illustrate the given phenomena. Conclusion : Cancer patients wanted considerate understanding and sincere care from nurses while they experienced physical and emotional suffering owing to the cancer, treatment trajectory, and hospital system. To improve the quality of nursing care for cancer patients, patient-centered care combined with nurses' expertise in oncology care must be provided based on the insights from our study's findings.

Purpose: The purpose of this study was to examine the meaning and essence of suicide for elderly people who had previously attempted suicide as an older person. Methods: Giorgi's descriptive phenomenology was used for analysis. The researchers carried out in-depth interviews, recordings and memos individually with four elders. The elders were individuals who had attempted suicide sometime in the past 5 yr. They were interviewed from 5 to 10 times using open-ended questions and a semi-structural format. Demographic data were also collected. Results: The meaning of suicide before a suicide attempt in older people had four core components: conflict with family, powerlessness and despair in their life with a drop in self-esteem, using internal and external resources to resolve their troubles and awareness of imminent crisis. Conclusion: These results of this study will increase understanding of suicide in older people by defining their subjective experience of suicide attempts and applying grounded data in the development of programs that provide concrete intervention strategies to prevent suicide in elderly people.

The purpose of this study was to investigate social workers' personal experiences providing social support to multi-cultural family in a multi-cultural family center. The data were collected through in-depth interviews with 14 social workers at the multi-cultural family center, and were analyzed using a phenomenological research method. The major findings were as follows : The social workers' personal experiences with and understanding of social support were classified as 4 categories : 'source of emotional support to the multi-cultural family', 'diverse and systematic educational support', 'excessive demands on material support', and 'daily life support and connection with community network'. The social workers recognized emotional and educational support as essential factors in providing social support to multi-cultural family. However, the social workers' perceptions of material support derived from negative personal experiences stemming from excessive demands and misunderstanding for material support. These results showed that social workers at the multi-cultural family center provided multi-cultural families with social support and that they interacted with community support system and multi-cultural families to increase their satisfaction.
