This study is designed to investigate social worker's experience in community practice at community welfare centers. Especially this study is conducted to identify the question; how do social workers experience community practice? For the study, data is collected from 11 social workers by depth interview. Using the Grounded theory, the data is analysed by open coding, axial coding, and selective coding. Finally the core category is become known that community practice is the piled up process of developmental experience throw willful efforts and various strategies under poor circumstances. The findings are as follows: (1) the experienced social workers seriously consider residents, community, social workers, and community welfare centers as the core participant in community practice. (2) the experienced community practitioners use various strategies on the whole process. (3) a system needs to be built to train community practitioners based on the cooperation of universities and community centers.

본 논문은 인공신경망과 귀납적 학습방법 등의 인공지능 방법과 선물가격결정에 대한 기존 재무이론을 사용하여 일상어휘로 표현되는 파생상품 가격예측 모형을 개발하는데 있다. 모형의 개발은 1단계로 인공신경망이나 기존의 선물가격결정이론(평균보유비용모형이나 일반균형모형)을 이용하여 선물 가격을 예측한 후, 서로 비교분석하여 인공신경망 모형의 우수성을 확인하였다. 귀납적 학습방법중 CART 알고리듬을 사용하여 If-Then 규칙을 생성하였다. 특히 실용적 측면에서 선물가격의 일상어휘화를 통한 모형개발을 여러 가지 방법으로 시도하였다. 이러한 선물가격 예측모형의 유용성은 일단 If-Then 규칙으로 표현되어 전문가의 판단에 확실한 이론적인 근거를 제시할 수 있는 장점이 있으며, 특히 의사결정지원시스템으로 활용화 될 경우 매우 유용한 근거자료로 활용될 수 있다. 이러한 선물가격 예측모형은 정확성은 분석표본과 검증표본으로 나누어 검증표본에서 세가지 기본모형(평균보유비용모형, 일반균형모형, 인공신경망 모형)과 각 모형의 귀납적 학습방법 모형의 다른 3가지 어휘표현방법 3가지를 모형별로 비교 분석하였다. 분석결과 인공신경망모형은 상당한 예측력을 갖고 있는 것으로 판명되었으며, 특히 CART를 기반으로 한 일상어휘 기반의 선물가격예측 모형은 예측력이 높은 것으로 나타났다.

The purpose of this study is to discover the nature of users' flow experience in virtual reality education services. To this end, we analyzed the factors that affect the user's immersion in virtual reality by applying grounded theory, which is one of the qualitative research method. An experiment was conducted on 11 subjects who were interested in conducting virtual reality education, and conducted interviews after experiments. All of the interviews were documented and configured to construct a paradigm model through the steps of opening coding, axial coding, selective coding. Based on the results, it presents suggestions for future virtual reality education services.

The purpose of this study is to explore the contents and process of sexual harassment experience in digital games. We interviewed 12 Female gamers and analyzed their experiences through grounded theory. In the paradigm model, the core phenomenon was psychological confusion and influence. Various causal, contextual and interventional conditions have been identified. The strategies were 'direct and passive action', and 'anger expression'. The consequences were 'decreasing the value of game' and 'negative perception of Korean society and men'.

Attempts are being made to investigate temperatures dependence of minimum ignition energy (MIE) based on concept of quantity of heat and thermal ignition theory. Regression equations for predicting MIE by means of temperature variations on the basis of statistical and mathematical methods are proposed. This study is undertaken to learn what proposed method is satisfactory hydrocarbons(propane and pentane). The proposed method has been tested and compared sucessfully with previously reported data in various journal.

This was a qualitative study to explore and better understand the adaptation experience and processes of peoples with fibromyalgia syndrome (FMS), as well as to develop a substantive theory using the grounded theory method. There were 13 patients (12 females and 1 male) who received FMS treatment from Rheumatic Medicine outpatient department of one general hospital. The data were collected through an in-depth interview between January and May of 2014. Transcribed interview contents were analyzed by the grounded theory method of Corbin and Strauss (2008). As a result, a total of 98 concepts, 26 sub-categories, and 10 categories were identified through the open coding process. The process of adaptation experience showed 4 steps: perception of uncertainty and limited condition, evaluation of self-control possibility and determinations of expectations of life, searching and trying of strategies, as well as self-regulation. The 4 types of adaptation experience were expansionary, complacently, effusively and withering. The 'protective self-regulation' theory was derived from the core category of 'learning to self-regulation method'. Patients with FMS has repeatedly attempted these strategies of protective self-regulation in order to gain stability from uncertainty and limited condition of the disease. Based on these results, it is necessary to develop an educational program for patients and families which has appropriate nursing intervention strategies in accordance with the types of adaptation.

The purpose of this study is to establish fundamental knowledge on the experience for building resource system using the social networks within the community. This study used a social capital perspective and the grounded theory method based on Strauss and Corbin(1998) and Corbin(2004). Interviews were conducted with 14 Korean social workers (general managers and assistant managers) at community welfare centers who have developed resources by using the social networks or social relations for more than 3 years. In creating autonomy and sustainability of community, there are four types of social worker's efforts in building resource system within the community: 'restoring norms of reciprocity', 'developing citizen's capabilities', 'mobilizing resources through community organizations', and 'utilizing external resource-networks'. These results are contribute to developing theory on social welfare resources using community networks according to characteristics of a community.

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.

This study, based on grounded theory, explores the child-rearing process of defecting North Korea women in South Korea. Interviews were conducted with five defecting North Korea women who had children. With the permission of the participants, the interviews were recorded with the digital recorder and transcribed by the researchers. Data were collected with in-depth interviews and observations until they were saturated. The interviews were analysed according to the constant comparative method used in grounded theory. The study derived 86 concepts, 31 subcategories and 11 categories in open coding. A core category was 'enduring hardships with hopes for children's success ' in selective coding. And The child-rearing process of the defecting North Korea women takes 'stage of entry', 'stage of confrontation', 'stage of struggle', 'stage of adjustment' and 'stage of hope for children's success'. The findings of the study will be useful in seeking an effective social welfare intervention plan for successful child-rearing of defecting North Korea women in South Korea.

The purpose of this paper is that which behavior is affected by the storytelling for the visually impaired children. I had a depth interview with the children and their parents who were Participated in the storytelling class, the storytelling teacher and the librarian. And then the material was analysed by the grounded theory. As a result of this research, storytelling is very helpful for the visually impaired children to improve their interest in reading, learning ability and their sociality.
