  • The paper presents a methodology to model three-dimensional reinforced concrete members by means of embedded discontinuity elements based on the Continuum Strong Discontinuous Approach (CSDA). Mixture theory concepts are used to model reinforced concrete as a 3D composite material constituted of concrete with long fibers (rebars) bundles oriented in different directions embedded in it. The effects of the rebars are modeled by phenomenological constitutive models devised to reproduce the axial non-linear behavior, as well as the bond-slip and dowel action. The paper presents the constitutive models assumed for the components and the compatibility conditions chosen to constitute the composite. Numerical analyses of existing experimental reinforced concrete members are presented, illustrating the applicability of the proposed methodology.

  • The Purpose of this study is to understand the meaning and the essence of suffering as viewpoint and to find the meaning and structure of the experience from encounters with patients in their terminal stages of illness. Method: A descriptive design based on the phenomenological approach model developed by Collaizzi was used. The period of data collection was from August to November of 2000. Data collection was conducted by open-ended and audio-taped interviews. The participants were nine female nurses who were willing to take part in this study. Results: Results of this study were classified into five main categories. The main category clusters were "difficulty in experiencing suffering," "professional challenges to expert nurses," "formation of empathic relationships," "expanding consciousness through suffering," and "alleviation of the patient's suffering." Conclusion: In conclusion, the implications for providing nursing care to end-stage patients in the throes of suffering is both rewarding and stressful. However, sharing these research results may help other nurses discover and experience deeper meanings in their own practice and careers.deeper meanings in their own practice and careers.

  • Purpose: This study aimed to explore university students' views on a childbirth to gaining a deeper understanding of their individual thinking and the meaning that it hold for them. Methods: A Phenomenological approach was used. Subjects were 10 university students who go to university in D city. The method proposed by Colaizzi (1978) was used to guide the process of data analysis. Results: The formulated meaning were classified into nine themes. And then the nine themes were finally grouped into five theme clusters as follow: 'a smooth life', 'the law of nature', 'living a real life', 'fear and burden'. Conclusion: University students' views on a childbirth reflect with the run of the lower birth rate and the aging population in Korean society. Therefore, nursing interventions should be directed toward supporting their positive thinking and changing their negative thinking on childbirth.

  • It has been reported that many slope failures in unsaturated soils are mainly caused by downward infiltration due to rainfall. The rainfall characteristics could be an important factor, and more predictable slope failures can be achieved by considering more reasonable rainfall conditions. So, a need exists that these trends of infiltration in weathered soils, which is commonly found in Korea, are assessed by considering rainfall conditions based on phenomenological approach. In this paper, numerical analyses of unsaturated soil slope under rainfall conditions are presented based on the soil-water characteristic curve in the laboratory and huff method. Then the performance of unsaturated weathered soil slopes was evaluated under various conditions after applying the effect of overburden pressure on SWCCs and fines contents. The results demonstrated that the rainfall conditions using Huff method can be very effective and the proper application on analysis is very important to enhance the prediction on unsaturated slope stability.

  • This qualitative nursing research used a hermeneutic phenomenological approach to discovery of meaning of the nursing students' clinical experience in junior colleges. Data collecting was utilized by in- depth face-to-face interviews of 10 sophomores who were participating in their first clinical experience. The following themes of the experience emerged. 1) The first step of fear (fear, being embarrassed) 2) Rhythmical patterning of theory and practice(disappointment of nurses, recognition of the gap between the theory and practice, the conflict between medical doctors and nurses, trouble with the students from other colleges, confusion from nurses' educational and noneducational attitudes, burden of responsibility for nurses' jobs, and the tiresome nature of repeated practice) 3) Discovery of changing self, awareness of self-expansion (awareness of professional nurses' roles, formation of self-confidence, changing of one's state of mind) From this study essential theme of clinical experience of nursing student's was identified, and continuous efforts to establish better adaptation of nursing students to clinical practice are required.

  • Purpose: The purpose of this study was to investigate conflicts and the experiences of conflict resolution of hospital nurses. Methods: This qualitative study used phenomenological methodology. The research participants were 8 nurses of C hospital. Data were collected through in-depth individual interviews from November 2016 to February 2017. The data analysis method was based on Colaizzi's approach. Results: The study results showed that the experiences of nurses consisted of 15 themes and 6 theme clusters: 1) Ambiguous role, 2) Recognizing lack of competence, 3) Difficulty maintaining relationships, 4) Unsatisfactory work environment, 5) Efforts to resolve conflicts, and 6) Conflict resolution process through labor union. Conclusion: The findings of this study recommend that hospital organizations and managers should pay attention to improving the work environment and organizational culture of members. The results of the present study can improve the understanding of various aspects of the daily life of hospital nurses.

  • A magnetic cataclysmic variable has a rotating magnetic white dwarf which accretes matter from its late type companion. Kim & Beuermann (1995) presented a phenomenological model of the accretion from its surrounding structure e.g., a disk into the magnetosphere of the white dwarf, and presented results for the spin modulated X-ray spectrum and light curves. Using this model, we calculate the optical continuum and line emission which result from reprocessing of X-rays in the accretion stream within the magnetosphere. Penning (1985) suggested the observed spin-modulated radial-velocity variations might result from reprocession of X-rays in the disk. We, however, find the radiation can be originated from the magnetosphere accretion stream. We use the same geometrical model to calculate the optical and the X-ray behaviour. The results from the two wavelength bands are internally consistent. We conclude that this approach will increase the diagnostic accuracies of the results.

  • The correlation between the optical performance of the reflective polarizer, which is a key optical component for the brightness enhancement of the liquid crystal display (LCD), and the configuration of optical sheets was investigated in a direct-lit CCFL (cold-cathode fluorescent lamp) backlight. The optical gain of the reflective polarizer, the polarization state of the light emitted from each film, and the loss factor for the polarization conversion process occurring in the lower part of the backlight were determined using a phenomenological approach for the polarization recycling process. The present study suggests that the correlation between the optical performance of the brightness enhancement films and the backlight configuration should be carefully considered in the optimization of the backlight structure.

  • An empirical functional form was suggested for the analysis of the emission spectrum of high-power light-emitting diode (LED) consisting of a sharp blue peak from the LED chips and a broad yellow peak from the phosphor layer. The peak positions, half widths, shape parameters, and amplitudes of these two peaks were reliably obtained as a function of the temperature, and the results were discussed qualitatively in relation with the junction temperature. The adoption of an inert liquid was found to have significantly reduced the LED temperature and the color shift of the emitted light. The phenomenological approach used in this study may be helpful in the simulation of the LED spectrum under various thermal conditions, and may thus be helpful in the improvement of the device performance.
