A new kind of 'All Ceramic Crown' could be manufactured by making improvements in the manufacturing technique for the current 'All Ceramic Crown' which does not use a special ceramic but rather a general one as a substitute. If we use the manufacturing technique for the 'All Ceramic Crown', metal coping and core are not produced. The effects of the new manufacturing technique for the 'All Ceramic Crown' are as follows: First. We do not need to use new material or special machinery or tools. Second. We can use general machinery and tools. Third. Using the basic 'All Ceramic Technique', we anticipate improvement in learning in our students. Forth. We can save effort, materials and time. Fifth. The technique also has advantages for esthetic 'temporary crown'.

The paper presents functional modelling and its application for diagnosis in nuclear power plants. Functional modelling is defined and its relevance for coping with the complexity of diagnosis in large scale systems like nuclear plants is explained. The diagnosis task is analyzed and it is demonstrated that the levels of abstraction in models for diagnosis must reflect plant knowledge about goals and functions which is represented in functional modelling. Multilevel flow modelling (MFM), which is a method for functional modelling, is introduced briefly and illustrated with a cooling system example. The use of MFM for reasoning about causes and consequences is explained in detail and demonstrated using the reasoning tool, the MFMSuite. MFM applications in nuclear power systems are described by two examples: a PWR; and an FBR reactor. The PWR example show how MFM can be used to model and reason about operating modes. The FBR example illustrates how the modelling development effort can be managed by proper strategies including decomposition and reuse.

The purpose of this study was to describe the relationship between family stress and adaptation in families with a disabled child through literature review using McCubbin's Double ABCX family crisis framework. The literature review focused on (1) family stress and factors affecting family stress, (2) the critical individual, familial and social resources which families acquire and employ over time in managing crisis situation. (3) the changes in definition and meaning families develop in an effort to make sense out of their predicament. (4) the coping strategies families employ. and (5) the range of outcomes of these family efforts The results showed that families reported financial difficulties and the burden of care-giving demands as major family stressors. Siblings of disabled children manifested depressive symptoms and social isolation. but was not consistent study results. The parents' views of the cause of the disabling condition fundamentally affected their behavior toward their disabled child. Especially. the fathers' views of the child's characteristics made the greatest contribution to positive changes in the mothers' perceptions. The term perceived social support refers to the cognitive appraisal by individuals that they are cared for and valued, that significant others are available to them if needed, and that they are satisfied with their interpersonal relationships. The perceived social support was more protective than social support source. network size and network density. Parental adaptation was found to be related to the child's communication competence rather than family coping strategies proposed by Lazarus and Folkman. One study results showed that there was no difference in depressive symptoms and physical health between mothers with a disabled child and those without all though mothers with a disabled child had negative attitudes and perceived themselves as having significantly less social support and lower family functioning. But a longitudinal study revealed decreases in the negative impact of the child and increases in sibling and overall family adaptation.

Purpose: The aim of this study was to develop a substantive theory on self-management conducted by the adolescents with chronic kidney disease from their lived experience. Methods: Data was collected through in-depth interviews from May to December in 2015 with thirteen adolescents with chronic kidney disease. The data collected were analyzed on the basis of Strauss and Corbin's grounded theory. Results: The core of the category found in this study was "overcoming the unstable sense of self- control and integrating disease experience into their life". The causal conditions triggering the central phenomenon were "restriction in daily life" and "manifestation and aggravation of symptom". The central phenomenon in the experience of self-management within the adolescents with chronic kidney disease was "unstable sense of self control". The intervening condition for unstable self control were "micro system support" and "motivational resources". This study found that the adolescents with chronic kidney disease followed a series of strategies when they faced the central phenomenon, including; passive coping, reappraisal of illness, active coping, compliance with treatment, controlling physical activity, and adjusting school life. With these strategic approaches, the adolescents with chronic kidney disease could maintain their active lifestyles and achieve their health behaviors. The process of self-management by these adolescents passed through four phases; limited experience caused by diseases, effort for normalization, reorganizing their daily lives, and integration with daily lives and self-management. Conclusion: This Study explored the process and experience of self-management of adolescents with chronic kidney disease. These findings can be used for basis for developing substantive theory and nursing intervention strategy for adolescents with chronic kidney diseases.

In-depth interview research and qualitative methodology were used to find changes in the experiences of family volunteer activities through the use of the Health Family Support Center. Ultimately, 143 items as sub-concepts, 42 items as sub-categories, and 10 items as subjects were found. I will also suggest alternative basic and primary data. First, using 10 subjects, the following points were evaluated in detail. I looked at what kind of changes in the volunteer activities these subjects experienced after working at the Health Family Support Center, and what the specific underlying reasons were for the changes in their family volunteer experience. These included 'community solidarity', 'family community', 'leisure and culture for the family', 'communication', 'personal relations', 'coping skills', 'growth', 'sympathy', 'positive thinking', 'future plans'. Second, families experienced a feeling of belonging as community members and the family realized the importance of their life, learned communication methods and coping skills. Third, families came to have new opportunities to grow as humans and learned a feeling of sympathy for others. Fourth, families found new paradigms to think positively about their daily life and to establish future plans. We will need more effort to empower family experiences of family volunteer activities that use the Health Family Support Center as well as supporting its staff. The following specific factors were the main mediating factors for using such a facility: family volunteer education, family volunteer service agency consulting, program planning, and managing family volunteers and other services.

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.

Many studies have shown that the parents of developmentally disabled children are adversely affected by the experience of raising a child of this type. However, the range of reactions to parenting a handicapped child is quite varied and is presumably affected by a wide variety of variables. This study examined a number of demographic and psychosocial variables to determine which particular combination could best predict the current level of stress and coping behavior of mothers. Among predictor variables, marital satisfaction and dysfunctional attitude are variables that I am particularly interested in which can mediate parental stress. Five variables are found to be related to the stress of mothers, that is, level of disability, level of needed help, marital satisfaction, type of disability, father's education level. Also variables that affect four different types of stress (which are four factors of QRS-F) are analysed and the results presented. Among these variables, some are pre-determined and some are intervenable. We should make an effort to make changes in those intervenable variables such as marital satisfaction, beliefs and attitude about disability, and level of needed help. In future research we need to search and clarify the beliefs and attitude that help mothers adjust to a life with a disabled child. Also governmental support and policy making to reduce the burden of these mothers should be accompanied as well.

Purpose: The purpose of this study was to understand and describe the every day life experience of patients with acute myocardial infarction (AMI) during the recovery period after Percutaneous Coronary Intervention (PCI) using a qualitative approach. Methods: Twelve patients with AMI participated in this study. Their age ranged from 42 to 75. The data were collected by individual in-depth interviews and all interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed using traditional qualitative content analysis. Results: Six sub-themes emerged from the data as follows: Getting to know about illness, getting motivated for health behavior, putting an effort into health behavioral change, having difficulties maintaining health behavior, setting up coping strategies for health behavior and having a need for a tailored education. The results of this study showed how the health behaviors of patients with AMI are related to their every day life experiences. Conclusion: The results of this study could help health professionals to better understand patients with AMI and design effective educational interventions to improve their health behaviors.

The rapid growth of blog has caused information overload where bloggers in the virtual community space are no longer able to effectively choose the blogs they are exposed to. Recommender systems have been widely advocated as a way of coping with the problem of information overload in e-business environment. Collaborative Filtering (CF) is the most successful recommendation method to date and used in many of the recommender systems. In this research, we propose a CF-based recommender system for bloggers to find their similar bloggers or preferable virtual community without burdensome search effort. For such a purpose, we apply the "Interest Value" to CF recommender systems. The Interest Value is the quantity value about users' transaction data in virtual community, and can measure the opinion of users accurately. Based on the Interest Value, the neighborhood group is generated, and virtual community list is recommended using the Community Likeness Score (ClS). Our experimental results upon real data of Korean Blog site show that the methodology is capable of dealing with the information overload issue in virtual community space. And Interest Value is proved to have the potential to meet the challenge of recommendation methodologies in virtual community space.
