  • This study has been performed to analyze the experience of parents who had led a parents-group of children with cancer. For this study, fifteen participants were selected for an in-depth interview and the personal experiences of each participant had been interviewed in person until data were saturated. This study employed the grounded theory approach of Strauss and Corbin(1998). With the qualitative constant comparative analysis, ninty four concepts, twenty six subcategories, and seventeen categories were generated. In the axial coding, a paradigm model was proposed as follows: The central phenomenon of the leaders' experiences was that they had been 'Pushed Back' to lead the groups. The causal conditions were 'A Sense of Solidarity', 'Regaining Self-possession', and 'Feeling a Necessity of Parents Group'. The contextual conditions were 'Want to Help', 'A Sense of Mission', and 'Discontent with the Cure Environment'. The intervening conditions were 'Self-reflection of Leadership', 'Reaction of Their Own Family', 'Hope to Have an Expanded Group'. The action/interaction strategies were 'Assuming All Field Work', 'Accumulation of Experiences', 'Recognition of a Role Scope'. The consequences were 'Being Comforted', 'Positive Self-awareness', 'a Sense of Worthiness', and 'Desire to Quit'. In the selective coding, the core category was 'Pushed to Lead a Group'. Based on the core category, four types and five stages in the leaders' experiences were identified. The types include 'a Devoted Family Type', 'a Volunteer Type', 'a Role Model Type', and 'a Activist Type': the stages consist of 'Stage of Maintain Identity as a parent of a child with cancer', 'Stage of Questioning', 'Stage of Active Participation', 'Stage of Experience Accumulation', and 'Stage of Progressive Change'. The result of this study presents some implications and suggestions for social work services and theories with respect to the self-help group of pediatric cancer by attempting to understand more about the experiences of leaders' in such groups.

  • This study explored the elementary school teachers' experiences while teaching students with low achievement in science based on the grounded theory. In-depth interviews and analysis were conducted on 13 teachers with experiences in teaching students with low achievement in science within the last three years and more than five years of field experience until the theoretical saturation of data on the teaching experiences for students with low achievement in science. The analysis results were as follows. First, the teaching experiences of elementary school teachers for underachievers in science were classified into 119 concepts, 41 subcategories, and 17 categories. Based on the paradigm model, the categories were structured and presented as causal conditions, contextual conditions, intervening conditions, action/interaction strategies and consequences based on the central phenomenon of 'difficulty in teaching students with low achievement in science'. Second, the core category of elementary school teachers' teaching underachievers in science was assumed to be 'overcoming difficulties and teaching underachievers in science'. And according to the properties and dimensions of the core category, teachers who teaching students with low achievement in science were divided into four types: 'compromising-', 'overcoming-', 'accepting-', and 'conflicting-reality type'. Third, a conditional matrix was presented to summarize and integrate the results of this study by classifying the teaching experience of elementary school teachers for underachievers in science into educational providers and educational demanders. On the basis of these findings, educational implications for teaching students with low achievement in science were discussed.

  • This Study was to explore the experience of foster care child's biological parents and proposed the practical discuss and method for support their returning home. We approached grounded theory to subject. Twenty biological parent's of foster child participated this research. The Data were collected by in depth-interview and documents. The authors analyzed the data according to frame that proposed Strauss and Corbin(1998). The results as follows: In open coding 143 concepts, 34 subcategory, 13 category. In axial coding the causal conditions were 「self-devaluation」, 「self-stigma」, 「social prejudice」. and the phenomenon were 「life as surplus being」, 「revolving around the world」, and the contextual conditions were 「collapse of life base」, 「rustical fatalism」. The intervention conditions were 「operation of support system」, 「instinct of maternity」. The action/interception strategy were 「closing of single eye」, 「pussling of scattered piece」. The consequence were 「fixations of abandonment」. 「resoaring to the world」 The authors proposed the core category as 「go over the wall of world burdening liabilities of being」. The authors classified patricians life type as 「challenging type」, 「status quo type」, 「escaping type」, Finally, we proposed the practical method for support restoring family the world」, foster care child's biological parents.

  • There has been considerable research recently on uncertainty handling in the fields of artificial intelligence and knowledge-based system. Various numerical and non-numerical methods have been proposed for representing and propagating uncertainty in knowledge-based system. The Bayesian method, the Dempster-Shafer's Evidence Theory, the Certainty Factor model and the Fuzzy Set Theory are most frequently appeared in the knowledge-based system. Each of these four methods views uncertainty from a different perspective and propagates it differently. There is no single method which can handle uncertainty properly in all kinds of knowledge-based systems' domain. Therefore a knowledge-based system will work more effectively when the uncertainty handling method in the system fits to the system's environment. This paper proposed a framework for selecting proper uncertainty handling methods in knowledge-based system with respect to characteristics of problem domain and cognitive styles of experts. A schema with strategic/operational and unstructured/structured classification is employed to differenciate domain. And a schema with systematic/intuitive and preceptive/receptive classification is employed to differenciate experts' cognitive style. The characteristics of uncertainty handling methods are compared with characteristics of problem domains and cognitive styles respectively. Then a proper uncertainty handling method is proposed for each category.

  • The purpose of this study is to understand the process of "standing alone" in divorced single fathers on the basis of qualitative data collected through in-depth interviews with 10 divorced single fathers. Data were analyzed on the basis of grounded theory analysis in open coding, and 154 concepts, 39 sub-categories, and 14 categories were derived. According to the results of this study, the process phenomenon of divorced single fathers' standing alone was "the restraint and chaos of pain". This study could identify the consecutive process of four identified stages: marriage life's rupture, pain and chaos, deliberation and decision, and role adaption. In selective coding, the core category was "to pass through the restraint of pain and embrace children and stand alone". There were three types of standing alone: maintaining barely, enduring hopefully, and living initiatively. This study showed the necessity of social support and the basic data by type analysis through the process of standing alone. This study provided substantive knowledge generated through the voices of the persons concerned.

  • Purpose: This study was to describe the process of healthy dieting and develop a substantive theory that explains lifestyle in obese male college students. Methods: The participants were 11 students who had participated in self-dieting program in a health center. Data were collected with in-depth interviews and analyzed by grounded theory in Strauss and Corbin (1990). Results: Through analyzing process, 36 concepts, 18 subcategories, and nine categories were deduced. In axial coding, casual condition, 'shrinking themselves' and 'oriented to selfish lifestyle', context condition, 'distress in mutual understanding' impacted on phenomenon, 'making health with autonomous living pattern'. Intervening conditions were 'practicing with active measures' and 'growing the willpower' and action-interaction condition, 'devoting realistic plan with positiveness' totally lead to consequence in 'regaining social relationship' and 'pursuing harmonious sound of mind and body'. The periods of process were divided four stages, reflecting self-characteristics, situational copping phase, applying period realistic strategies, and developing phase of social relationship. The core category, 'developing communication competency' incorporated the relationship between and among all categories and explained the process. Conclusion: The findings indicate that self leading health program helped to develop the communication competency. Therefore, we would consider about internalized motives and external incentives in health programs.

  • Purpose: This study was conducted to generate a grounded substantive theory of the adaptation process of mothers-in-law of Vietnamese women married to Korean husbands. Methods: Thirteen women who had Vietnamese daughters-in-law were interviewed. Data were transcribed verbatim and analyzed using a grounded theory method. Results: Eight categories with 19 sub-categories were extracted from 268 concepts. The identified phenomenon was 'overcoming differences' and the core category was 'trying one's best to live together with daughter-in-law'. The 9 categories were grouped into 3 stages for the adaptation process: encountering, struggling, and living together. Conclusion: The results indicate that when individuals from different cultural and personal backgrounds have to live together there is a continuing negotiation process towards meeting each other's needs. Health professionals can assist this adaptation process by providing these women with insights into various ways of meeting each other's need while they are struggling.

On Subject auxiliary inversion in English (주어-조동사 도치에 관한 소고)

  • It has been one of the puzzles in the English syntax that so called the rule of subject-auxiliary inversion (SAI) is not allowed in subject wh-movement while it is not obligatory in non-subject wh-movement in a root sentence. This asymmetry has been a puzzle since SAI itself was thought to be a part of question construction as we can observe from yes/no questions. The asymmetry gets more complicated in terms of sentence embedding, i.e no SAI is permitted in the embedded context in question. The goal of this paper is to suggest an unified analysis for this unsolved grammatical phenomena on the basis of Rizzi (1997)'s recent work. The main idea is that SAI is not a I-to-C movement but one of I-to-Focus where Focus is a functional category and its phrase is located between CP and IP. The other proposal is that Wh-movement is no more homogeneous in terms of landing site between a root and an embedded sentence: the target for a wh-phrase in the former is the Spec of FocP (Focus Phrase) but the one in the latter is the Spec of CP as the standard theory assumes. Pesetsky (l999)'s analysis is discussed and its theoretical and empirical shortages are pointed out. Its rather radical proposals such as the one that the nominative case is just an uninterpretable tense feature of DP and the other that 'that' is no longer a complementizer but an element of I(nflection) make it less acceptable in spite of the possibility that it can get rid of Case theory entirely, which would be ideal in the spirit of minimalism.

  • Purpose: The purpose of this study was to explore the experiences of recovery from disease in the patients doing a kind of Buddhist meditation, and to develop a grounded theory about meditation. Method: Data was collected by an in-depth interview using tape-recordings from sixteen participants doing meditation. The data was analyzed using the grounded theory method proposed by Strauss and Corbin(1998). Result: The core category was discovering the true self. The participants began to do meditation because of their disease. They experienced obstacles due to incomplete religious acceptance. However, their faith grew gradually based on religious experiences that were indescribable. Finally, they entirely trusted the inner healer, which is emphasized in meditation. The strategies that they used were self reflection and seeking help for accepting deep meditation. They were stabilized in physical, psychological and social daily living. The processes of discovering the true self were identified as entering religious discipline, embodying religious discipline, self-accomplishing religious faith, and recovering mind-body health. Conclusion: This study provided the understanding of mind-body integration. Empirical research may be needed to prove scientifically the effects of meditation.

  • Purpose: This study aimed to explore the breast feeding process of mothers and to develop a grounded theory about experiences of breast feeding women. Methods: Data was collected by means of an in-depth interview from 8 participants who were breast feeding their baby. The data was analyzed using the grounded theory methodology proposed by Strauss and Corbin. Results: The core category was discovered to be 'becoming a mother'. This process was categorized into 5 stages; 'facing difficulties of breast feeding', 'having the will to continue to breast feed', 'doing one's best to breast feed', 'feeling satisfaction with one's breast feeding', and 'retaining a lingering desire for one's breast feeding'. Mothers began breast feeding without preparation. They faced difficult problems during breast feeding such as getting a lay-person's or professional person's support. They made various efforts for continuing to breast feed and solve the problems. They got pleasure from breast feeding, their baby is fine, and they have a bond with their baby. Finally, when they finished breast feeding, they still felt attached to it and had regrets. Conclusion: This study provided the information about mothers' experiences in the breast feeding process. Therefore, nurses will be able to utilize successful adaptation skills for helping breast feeding mothers.
