This study applied hermeneutic grounded theory suggested by Rennie to understand general meaning of adoption decision process of 7 non-married mothers. At the end of the analysis, 191 meaning units, 46 subcategories, and 11 hermeneutic categories were constructed. The core category that threads throughout the adoption decision process was represented as "living with a scar left by the duality of motherhood; repudiating and embracing." The adoption decision process emerged as recognition of pregnancy, avoidance of reality, searching for adoption, escalation of confusion, determination and rationalization or forfeiture. Based upon our research, we suggested that the adoption decision process of non-married mother was another way of practicing motherhood, and we proposed that we need to develop a psycho-social support program to improve the lives of non-married mothers.

As an estimate of a location parameter for a given data set, $\alpha$-trimmed mean has been studied for a long time by many statisticians because of its nice propoerties including robustness. However, its performance depends on the proportion of trimming say $\alpha$. In this paper, we suggest a data-driven choice of $\alpha$ and study its validity. Also, we suggest a new estimator and consider double-bootstrap to improve its performance. By using simulation study, the proposed method is compared with the exiting one in various cases. Real data sets are also analyzed by using the proposed method.

Research on the method of calculating and estimating evapotranspiration has been steadily conducted. Various models have been developed according to different backgrounds, and each of these models has different characteristics such as required input data. Therefore, this study introduces the theoretical background and characteristics of evapotranspiration models and the development process of domestic research on evapotranspiration by era. First, the origin and theoretical background of the potential evapotranspiration models are summarized in addition to classifying them by input data. Then, the characteristics of the actual evapotranspiration estimation methods are summarized. Additionally, methods based on observation and methods using the rainfall-runoff models are summarized.

The purpose of this study is to conceptualize the process of formation by the exploration of the lives of professional golfers who grow to excellent sports leaders, categorize the concept and suggest models between categories. In order to reveal in depth the change process of the job formation, the 'grounded approach' as a qualitative study was used as a the methodological frame of this study, and snow sampling, one of nonrandom sampling was used for the selection method of the study participants. 10 study participants who are able to make positive self-expression and talk with the researcher were selected. Through grounded approach appropriate for this process research, this study could acquire following results. First, through the casual condition that is the exploration of the lives of professional golfers growing to excellent sports leaders, it connected to the central phenomena of professional instruction methods and education belief as golf leaders. In this process, the changes as new experiences for the charm of the new job and relationship formation influence as the function of a contextual condition. In addition, golf leaders tried to become a more completed golf leader through self-efforts for development and expertise attainment according to the their own situations as well as belief, and they have established the lives of firm golf leaders through the process. Second, as a result of the changes of their lives as professional golfers growing to excellent sports leaders, the paradigm of grounded approach which is abstracted as total 141 concepts, 17 subcategories, and 11 superordinate categories were composed.

The purpose of this research was to conduct grounded-theory-based explorations on the types of motivation that make pre-service elementary school teachers learn science and on their type-based science-learning processes. One hundred thirty-two pre-service elementary school teachers' motivation types were analyzed, and amongst them, 12 were selected as the subjects to observe their science-learning processes to which grounded theory applied. As a result of analyzing their science-learning motivation types, it was found that the majority belonged to the type "accurators", followed in descending order by the types "directors", "explorers", and "coordinators". Coding various phenomena that appeared in their science-learning processes made it possible to derive 30 categories from them according to the grounded-theory paradigm model elements. Based on such categories derived, analysis could be made on their science-learning process flows by motivation types, according to the grounded-theory paradigm model. For example, the "accurators" were attending science lectures or reading science books to learn science knowledge and how to teach it, from a sense of obligation they took for granted as elementary school teachers. Although their experiences of science-learning processes could not be from pure intentions, due to the teacher certification examination, curriculum, or other environmental factors, they were found to have new perspectives on science with their individual efforts and participations.

The purpose of this study was to improve the understanding of essential experiences of children of Alcoholism and explore their adjustment process from the children's perspectives. The specific research questions explored in this study were: 1. What was the central phenomenon that children of Alcoholism have experienced? 2. What was the adjustment process of the children of Alcoholism. The grounded theory was adopted in this study to address the research questions. Data was collected through in-depth interviews with eight young adult aged from 18-30 years olds who experienced their parent's Alcoholism. Grounded theory based data analyses resulted in 85 concepts, 30 sub-categories, and 16 categories. The 'causal conditions' influencing the central phenomenon was 'self denial' and 'being suppressed' is the central phenomenon for the children of Alcoholism. The core issue in the process of an adjustment of children from a Alcoholism family was 'accepting the parental Alcoholic problem and re-defining the self', The results of this study suggest that counseling interventions are suggested to improve children's well-being and facilitate their adjustment. Therefore this study has implication on building theory of intervention on the offsprings who have parents of Alcoholism.
