  • Purpose: The purpose of this study was to explore the experience of patients on the waiting list for kidney retransplantation. Methods: The data were collected by individual in-depth interviews of nine patients who were dialyzed after primary kidney graft dysfunction and were waiting for deceased donor kidney retransplantation. All interviews were audio-taped and transcribed, and were analyzed using a phenomenological method. Results: The findings included 5 theme clusters and 13 sub-themes. The 5 clusters were 'Diagnosed with chronic renal failure and dialysis: Broken daily life and crisis', 'Kidney transplantation: The only way to escape from dialysis', 'Kidney graft failure: Inevitable moving backward to hemodialysis', 'Self-management of re-dialysis patients: Growth through pain', and 'The waiting for kidney retransplantation: To try again in the hope of getting a new life'. Conclusion: This study provides a deep understanding of patients with dialysis who are waiting for deceased donor kidney retransplantation. On the basis of the findings of this study, health professionals can provide customized information and develop effective nursing interventions to improve the self-management of these patients.

  • Tensile and low cycle fatigue tests on prior cold worked 3l6L stainless steel were carried out at various temperatures ftom room temperature to 650$^{\circ}C$. Fatigue resistance was decreased with increasing temperature and decreasing strain rate. Cyclic plastic deformation, creep, oxidation and interactions with each other are thought to be responsible for the reduction in fatigue resistance. Currently favored life prediction models were examined and it was found that it is important to select a proper life prediction parameter since stress-strain relation strongly depends on temperature. A phenomenological life prediction model was proposed to account for the influence of temperature on fatigue life and assessed by comparing with experimental result. LCF failure mechanism was investigated by observing fracture surfaces of LCF failed specimens with SEM.

  • In a prevailing view of meaning and reference (cf. Frege 1892), words pick out entities in the physical world by virtue of meaning. Linguists and philosophers have argued whether the meaning of a word is inside or out-side language users' mind; but, in general, they have taken it for granted that words refer to entities in the physical world. Hilary Putnam (1975), based on his famous twin-earth thought experiment, argued that the meaning of a word could not be inside language users' head. In this paper, I point out that Putnam's argument makes sense only if words refer to entities in the physical world. That is, Putnam did not provide any argument against mentalistic semantics, since he erroneously assumed that meaning, but not reference, was inside our mind in mentalistic semantics. Mentalistic semanticist, however, assume that words pick out their references inside our head (instead of a possible outside world). A number of arguments for the mentalistic position come from psychology: studies on emotion and visual perception provide numerous cases where words cannot pick out entities from the physical world, but inside our head. The mentalistic theory has desirable consequences for the philosophy of language in that some classical puzzles of language (e.g. Russell's (1919) well-known puzzle of excluded middle) are explained well in the proposed theory.

  • This study is to propose the possibility of narrative or story as a research methodology in the field of library and information science. To do this, I discuss the power and possibility of storytelling as a epistemological method of social science. Later, I look into turn to narrative in western scholarly traditions. And then, I introduced the process and the characteristic of the narrative inquiry as a subject and a methodology of research. I compare to another research methodology, ethnography and phenomenological research. At last, I reviewed the literature which is conducted by the methodology of narrative inquiry in the field of library and information science. I consider the possibility of adaptation of narrative inquiry in the field.

  • Within the context of continuum mechanics, inelastic behaviours of constitutive responses are usually modelled by using phenomenological approaches. Elasto-plastic damage modelling is extensively used for concrete material in the case of progressive strength and stiffness deterioration. In this paper, a review of the main features of elasto-plastic damage modelling is presented for uniaxial stress-strain relationship. It has been reported in literature that the influence of Alkali-Silica Reaction (ASR) can lead to severe degradations in the modulus of elasticity and compression strength of the concrete material. In order to incorporate the effects of ASR related degradation, in this paper the constitutive model of concrete is based on the coupled damage-plasticity approach where degradation in concrete properties can be captured by adjusting the yield and damage criteria as well as the hardening moduli related parameters within the model. These parameters are adjusted according to results of concrete behaviour from the literature. The effect of ASR on the dynamic behaviour of a beam and a column are illustrated under moving load and cyclic load cases.

  • The predictive utility of a damage model depends heavily on its particular choice of a damage variable, which serves as a macroscopic approximation in describing the underlying micromechanical processes of microdefects. In the case of spatially perfectly randomly distributed microcracks or microvoids in all directions, isotropic damage model is an appropriate choice, and scalar damage variables were widely used for isotropic or one-dimensional phenomenological damage models. The simplicity of a scalar damage representation is indeed very attractive. However, a scalar damage model is of somewhat limited use in practice. In order to entirely characterize the isotropic damage behaviors of damaged materials in multidimensional space, a system theory of isotropic double scalar damage variables, including the expressions of specific damage energy release rate, the coupled constitutive equations corresponding to damage, the conditions of admissibility for two scalar damage effective tensors within the framework of the thermodynamics of irreversible processes, was provided and analyzed in this study. Compared with the former studies, the theoretical formulations of double scalar damage variables in this study are given in the form of matrix, which has many features such as simpleness, directness, convenience and programmable characteristics. It is worth mentioning that the above-mentioned theoretical formulations are only logically reasonable. Owing to the limitations of time, conditions, funds, etc. they should be subject to multifaceted experiments before their innovative significance can be fully verified. The current level of research can be regarded as an exploratory attempt in this field.

  • Purpose: The purpose of this study were to identify the essential component and meaning structure of the experience of 'Sockalee' among abused elders. Method: This study was done using a phenomenological analytic method by Giorgi. The participants in this study were six elders who had the previous experience of 'Sockalee' as abused elders. The data were collected by interviewing the participants from May to September, 2003. Generally, three interviews for one person were performed and each interview lasted for one and half hours. Results: The meanings of 'Sockalee' of abused elders were categorized with seven components. Those are (1) Unsolved family conflicts. (2) Being powerless. (3) Being pushed out. (4) Egocentric situation-recognition. (5) Strengthening egocentric situation-recognition (6) Attempts for re-powerfulness. (7) Release from abuse. (8) Situation recognition with others' position considered. Conclusion: Therefore, the nursing intervention must be focused on the above concerns to accomplish the successful solution for the abused elderly problems, especially approaching from the standpoint of the whole human.

  • Purpose: The purpose of this study was to understand the nurses' experiences of end of life care of older adults with dementia living in long-term care hospitals and geriatric care facilities. Methods: The participants were nine nurses. Open in-depth interviews were used to collect data from June, 2016 to November, 2016. Colaizzi's phenomenological approach was used to analyze the data. Results: Three categories were identified. The nurses' reported experiences of end of life care of older adults with dementia were 'warm care with living together', 'care for family', and the 'self-reflection and responsibility as a nurse'. There were ten clusters of themes and 24 themes. The participants stated that the end of life care of older adults with dementia were individualized holistic care with dignity, being in older adults with dementia and family, and responsibility as a professional. Nurses reported the need for dementia hospice care. Conclusion: These results could be considered in planning nursing intervention for hospice care. The findings support the need for educational strategies and programs to improve end of life care among older adults with dementia.

  • As a process of Direct Containment Heating (DCH) issue resolution for Korean Standard Nuclear Power Plants (KSNPs), a containment load/strength assessment with two different approaches, the probabilistic and the deterministic, was performed with all plant-specific and phenomena-specific data. In case of the probabilistic approach, the framework developed to support the Zion DCH study, Two-Cell Equilibrium (TCE) coupled with Latin Hypercubic Sampling (LHS), provided a very efficient tool to resolve DCH issue. In case of the deterministic approach, the evaluation methodology using the sophisticated mechanistic computer code, CONTAIN 2.0 was developed, based on findings from DCH-related experiments or analyses. For three bounding scenarios designated as Scenarios V, Va, and VI, the calculation results of TCE/LHS and CONTAIN 2.0 with the conservatism or typical estimation for uncertain parameters, showed that the containment failure resulted from DCH loads was not likely to occur. To verify that these two approaches might be conservative , the containment loads resulting from typical high-pressure accident scenarios (SBO and SBLOCA) for KSNPs were also predicted. The CONTAIN 2.0 calculations with boundary and initial conditions from the MAAP4 predictions, including the sensitivity calculations for DCH phenomenological parameters, have confirmed that the predicted containment pressure and temperature were much below those from these two approaches, and, therefore, DCH issue for KSNPS might be not a problem.
