We considered qualitative behaviour of the generalization of Einstein's model of Brownian motion when the key parameter of the time interval of free jump degenerates. Fluids will be characterised by number of particles per unit volume (density of fluid) at point of observation. Degeneration of the phenomenon manifests in two scenarios: a) flow of the fluid, which is highly dispersing like a non-dense gas and b) flow of fluid far away from the source of flow, when the velocity of the flow is incomparably smaller than the gradient of the density. First, we will show that both types of flows can be modeled using the Einstein paradigm. We will investigate the question: What features will particle flow exhibit if the time interval of the free jump is inverse proportional to the density and its gradient ? We will show that in this scenario, the flow exhibits localization property, namely: if at some moment of time t₀ in the region, the gradient of the density or density itself is equal to zero, then for some T during time interval [t₀, t₀ + T] there is no flow in the region. This directly links to Barenblatt's finite speed of propagation property for the degenerate equation. The method of the proof is very different from Barenblatt's method and based on the application of Ladyzhenskaya - De Giorgi iterative scheme and Vespri - Tedeev technique. From PDE point of view it assumed that solution exists in appropriate Sobolev type of space.

연구의 목적은 장애뉴스에 특화된 인터넷 독립언론매체 에이블뉴스의 장애인활동보조서비스 갈등 보도에 나타난 주요 주제를 분석하고, 활동보조서비스 갈등에 관한 보도에 내재된 관점을 비판적으로 분석하는 데 있다. 이를 위해 본 연구는 에이블뉴스의 장애인활동보조서비스 갈등 관련 기사들을 자료로 하여 귀납적 질적 내용분석, 인과요소와 책임귀인분석, 장애패러다임분석을 실시하였다. 내용분석결과 에이블뉴스는 장애인활동보조서비스 갈등을 충실히 보도하고 있었으나 책임귀인 분석에 의하면 갈등의 원인과 해결을 장애인이용자와 활동보조인에게 귀인하는 경향이 두드러졌다. 또한 장애패러다임 분석결과 재활모델의 관점을 반영한 텍스트들이 적지 않아 자립생활모델과 밀접한 활동보조서비스 갈등을 보도하면서 독자들에게 재활모델의 관점을 전달할 우려가 있는 것으로 나타났다. 이러한 연구결과를 토대로 장애에 특화된 독립언론매체로서 보다 전문적인 보도를 위해 전문기자의 활용, 외부 전문기고자의 활용, 편집회의를 통한 기사 게재 등을 제안하였다.

This study defines copyrighted public records in broad sense including open government data and public domain except for some private records. Additionally, this study aims to investigate improvement plan for maximizing utilization of copyrighted public records in web-sites using customer side, without consideration of supplier side. For this purpose, qualitative study method was used with grounded theory on analyzed problems from literature review and case study. Literature review was concentrated on definition of open data and abroad utilization indicators whereas case study analyzed current situation of four web-sites providing copyrighted public records. Converged opinions from in-depth interview and various statistical data was analyzed as a basis for grounded theory, then a paradigm model was constructed and future improvement plans were presented. The findings imply that opening of copyrighted public records is not just important for quantitative results, rather it requires qualitative improvement providing latest credible information that is consistent with the demand of the customer. Thus, development of service platform and business models for copyrighted public records are urgent task.

Purpose: This study is a qualitative research on the adaptation of the spinal cord injury after fortuitous the accident. Methods: The subjects are fifteen spinal cord injuries. As a study method, this author employed Grounded theory, one of the qualitative research methods. For data analysis, the procedures of Grounded theory methodology was adopted, and then the data collection were collected for six months from March to September 2009. Concerning the frequence of interviewing, each participants went through individual interviewing twice at least and up to four times if necessary. Results: As a result of open coding, total thirty six concepts and twenty categories were drawn. To synthesize these categories, they came to choose 'Going into the new self-made spinal cord injury' as a nuclear category. Typological analysis based on the result of the paradigm model divided them into a reality-avoiding, passive coping, reality-maintaining, reality-overcoming, and self-fulfillment type. Conclusion: As a result of this study, family support to those with spinal cord disability is an important factor for their motive for rehabilitation and adjustment, spinal disabilities were accepted to mostly the disabilities in relations with colleagues. Thus it is necessary to give them a nursing intervention through disability group for successful adjustment to life with disability.

This study examined the retirement adaptation process for middle-aged and elderly couples. Twelve couples who had experienced retirement were recruited by theoretical sampling. Data were collected through in-depth interviews and analyzed through the grounded theory approach of Strauss and Corbin (1998). This study showed the results of 124 concepts, 41 sub-categories and 17 categories indicated through an open coding process. As a paradigm in axial coding, the causal conditions in the adjustment procedures of elderly couples whose spouses are retired were 'retirement preparation,' 'retirement acceptance,' and 'marital satisfaction.' A central phenomenon was 'crisis and conflicts of twilight couples.' The contextual conditions that correspond to this phenomenon were 'psychological separation from adult children,' 'division of household labor,' and 'economic status.' The action/interaction strategies to control the phenomenon were 'recognition of marital relationships,' 'conflicts coping,' 'resolution methods,' and 'self-reflection.' The intervening conditions that facilitate action/interaction strategies were 'attitudes of husbands,' 'mutual awareness of couple,' 'health status,' and 'support systems.' The consequences were 'readaptation of marital relationships,' and 'unresolved conflicts,' and 'trying alone.' This research classified middle-aged and elderly couples' adaptation into three types such as mutual effort, separation & resignation, and conflicts vestige. The findings provide basic information to develop a retirement adaptation program for the middle-aged and elderly.

This is qualitative research using grounded theory to examine the experiences that mothers of children with epilepsy can have. Data were collected through in-depth interviews, observation, and memo-taking with a total of 13 participants in this study-10 mothers taking care of children with epilepsy and 3 principal informants-and the data were analyzed using the method developed by Strauss and Corbin (1998). As a result of data analysis, 163 concepts, 26 subcategories and 8 categories were formed through open coding. Such categories were analyzed by the paradigm of the grounded theory, and as a result the experiences of the mothers of epileptic children were based on a causal condition of 'confrontation' and the central phenomenon of 'Wandering around the forest under a yoke'. The contextual conditions, which exerted influence on phenomena, were 'stigma cognition', 'personality traits' and 'health of children.' The action/interaction strategy selected by participants was 'Quietly pulling through: Bracing myself, Getting to know my enemy and myself, Taking care while hiding, Putting out one step at a time, Establishing a foothold. The intervening condition affecting action/interaction was 'the support system', and its result was 'watching.'

A major goal of the Community Plant Food Project is to develop partnerships between the Cornell Community Nutrition Program and Community-based organizations, including Cooperative Extension. A core principle behind this work is integrating research and intervention. Based on our work in Rochester, New York, we have developed a process and principles for effective partnerships. This new paradigm what we call the University-Community Partnership Model is a team effort that builds on the experiential literature in the fields of communication, leadership, community and team development, sociology, and participatory research and action. We have applied this model both to increase our understanding of Family Food Decision-making and to develop programs for families. In this project, we have used a variety of qualitative methods to understand food decisions from the perspectives of families and community stakeholders, including a group method for analyzing our qualitative interview data. For our survey of families, we developed the Enhanced Response Method, an approach for improving the validity and reliability of community surveys with families and, at the same time, building relationships with families and other stakeholders in the community for integrated and sustainable interventions. Because the knowledge we develop through the partnership and the interventions we seek to implement are products of the process, we are constantly seeking to refine this knowledge and to adapt emerging interventions through an ongoing evaluation process we call the Continuous Improvement Method.
