This study was conducted to identify an initial clinical experience of nursing students, so to better understanding to students' experience in clinical setting. The study subjects were 39 nursing students working in C department of nursing in C city. This study was approached by phenomenological method, collected data were analyzed by Colaizzi's method. The results were followed. From the protocol, 236 significant statements were organized into 56 formulated meanings. From formulated meanig, 27 themes were identified, organized into 13 theme clusters, and then into 6 categories. Theose nursing students experienced $\mathbb{\ulcorner}$tension$\mathbb{\lrcorner}$ in adjusting themselves to new clinical settings, $\mathbb{\ulcorner}$fear and anxiety$\mathbb{\lrcorner}$ in using unskillful nursing skills. They also went through $\mathbb{\ulcorner}$stress> by difficulties in applying their knowledge and skill to nursing practice, in lack of nursing knowledge and skill, in dealing with making interpersonal relationship with clinical staffs, in insufficiency of clinical instructions and in role ambiguity among nursing students. Physical $\mathbb{\ulcorner}$fatigue$\mathbb{\lrcorner}$ and $\mathbb{\ulcorner}$disappointment and doubt$\mathbb{\lrcorner}$ by the difference between reality and expectation caused by clinical experience. However, clinical experience enabled nursing students to enhance their understanding of human beings, learning, their satisfaction. to nursing practice, to identify the confirmation of nursing identity, so to gain $\mathbb{\ulcorner}$sense of accomplishment$\mathbb{\lrcorner}$. The results of this study are to use as basic data for students attending clinical experience for the first time.

Purpose: This study was done to explore the meaning and nature of life world for adolescents with epilepsy. The hermeneutic phenomenological method which was developed by van Manen was used. Methods: Participants were four boys and five girls, ages 13 to 18 being seen in a neurology outpatient department. Data were collected from iterative work with in-depth interviews from during the period from February to September, 2010. Contents of the interviews were tape-recorded with participant consent. Results: Essential themes that fit into the context of the 4 existential grounds of body, time, space and other people were: an illness that makes a hurt in one's heart rather than one's body, a change in the body that is not controllable, a future like thick fog, everyday life trapped in illness, a change of relationships, learning how to live with an illness. Conclusion: Findings reveal the life world of the adolescents is affected to varying degrees by the epilepsy. It is important for nurses to identify and address developmental issues and effects of the illness and to support reorientation in a disintegrated life situation. The result of this study will provide nurses with insights into these experiences and should help promote empathetic care.

The purpose of this study was to explore the experience of Pap smear screening of menopausal women in W city using a phenomenological methodology. The participants were 5 focus groups consisting of 37 menopausal women. They were selected using snowball sampling method. The data were collected through focus group interviews. Data were recorded and analyzed by Colazzi's method. Significant statements were extracted from the data resulting in 20 themes. These themes formed 12 clusters and 5 categories. The essential themes of the experience of cervical cancer screening emerged as : "unpleasant feelings during procedure", "ambivalent feelings about results", "be guided to seek health", "shrink from interaction with health professionals", "at ease about cervical cancer". The results indicated that cervical cancer prevention strategies for menopausal women need to be based on deep under standing of the personal experiences of Pap smear screening. In conclusion, it is suggested that more specified strategies are needed for menopausal women to encourage them to have regular screening.

The purpose of this study was to explore the structure of nursing needs during labor pain as perceived by women who have given birth. The phenomenological perspective of qualitative research theory guided the approach to the study. The sample consisted of 20 women who had undergone normal labor and had delivered a healthy baby at term. Collection of data was by means of in-depth interviews conducted 1-2 days after delivery in the admission room from March to may 1998. On average, the interviews lasted for about 30 minutes. Interviews were taken with the consent of the subjects. Data were analyzed by means of Giorgi's method and categorized according to the similarities of their contents. The investigator read the data repeatedly to identify themes and categories. Four categories were : 1) a sense of security 2) self esteem 3) willingness to learn 4) a sense of comfort. Under these categories there were twelve themes. I. A sense of security : (a) presence (b) conversation (c) touching II. Self esteem : (a) praise (b) encouragement (c) treating the women with respect (d) caregiver with good character III. Willingness to learn : (a) teaching (b) information IV. A sense of comfort : (a) self controlled pain relief (b) artificially controlled pain relief (c) skillfulness of caregiver The findings should sensitize nurses to the various needs of women in labor who are under their care. Further research should focus on developing instruments to assess the nursing needs of parturients. Researchers also need to identify ways to assess women's satisfaction with nursing needs.

In this study, I wanted to explore in depth the meaning of psychological phenomena experienced by Christian living alone. For this purpose, five male and female living alone aged 65 or older were interviewed in depth, and the data after the interview was qualitatively analyzed by Giorgi's method of phenomenological research. The study found five categories : 'feeling closer to death', 'loneliness due to lack of a partner to talk to', 'helplessness to a debilitated body phenomenon', 'disconnected relationships' and 'looking at God'. The findings that the faith proved to be an important factor of overcoming loneliness in the lives of the elderly, provide a foundation for understanding and the pastoral counseling of the elderly living alone in churches.

Purpose: The purpose of this qualitative study was to identify the nature of precocious puberty and to explore what it means in primary schools. Methods: The participants of this phenomenological study were nine primary school girls who were diagnosed with precocious puberty and experienced hormone therapeutics, applying a convenience sampling method. Data were collected from July 2017 to January 2018 through individual in-depth interviews of the participants, including gestures, facial expressions and nonverbal means. The data analysis followed the method of Giorgi. Results: The study identified 37 concepts, 12 clusters, and five themes from experiences of precocious puberty. The essential five themes were as follows: 'ashamed and concealing experience', 'there is no therapeutics option', 'difficulties in the process of therapeutics', 'difficulties in daily life', and 'ambivalence toward therapeutics'. Conclusion: The findings of this study indicate physical, psychological and social difficulties faced by girls with precocious puberty. Based on this results of the study, it is necessary to develop nursing intervention programs focusing on healthy growth and development for children with precocious puberty.

Endothermic fuels are known as a probable fuel for hypersonic atmospheric flight vehicles and advanced propulsion systems, as well as cryogenic fuels. Especially, from the standpoint of the advanced regenerative cooling use, they are quite useful as a coolant fuel because of their large heat sink due to their chemical decompositions; so-called endothermic cooling effect. However, no heat transfer equations have been proposed taking into account such endothermic reactive behaviors concretely. This paper describes an analytical method for evaluation of the heat transfer rates between endothermic reacting coolant fuel and coolant-side wall in the regenerative cooling passages. Heat transfer mechanism is indicated based on a classical transport-phenomenological approach. A new relational expression of Nusselt number ratio for forcedconvective heat transfer with such endothermic reactions is also proposed by theoretical approaches using some classical hypotheses. Its applicability is assessed provisionally by comparison with confirmed results of heated tube tests for supercritical JP-7 fuel carried out at NASA Lewis Research Center, using its heat sink characteristics evaluated by United Technologies Research Center(UTRC). As a result, it has been suggested that the proposed relational equation is applicable to the evaluation of enhancement of Nusselt numbers due to such reactions in developed turbulent flows such as in the regenerative cooling passages.

Large fluctuations in surface strain at the level of steel are expected in reinforced concrete flexural members at a given stage of loading due to the emergent structure (emergence of new crack patterns). This has been identified in developing deterministic constitutive models for finite element applications in Ibrahimbegovic et al. (2010). The aim of this paper is to identify a suitable probability distribution for describing the large deviations at far from equilibrium points due to emergent structures, based on phenomenological, thermodynamic and statistical considerations. Motivated by the investigations reported by Prigogine (1978) and Rubi (2008), distributions with heavy tails (namely, alpha-stable distributions) are proposed for modeling the variations in strain in reinforced concrete flexural members to account for the large fluctuations. The applicability of alpha-stable distributions at or in the neighborhood of far from equilibrium points is examined based on the results obtained from carefully planned experimental investigations, on seven reinforced concrete flexural members. It is found that alpha-stable distribution performs better than normal distribution for modeling the observed surface strains in reinforced concrete flexural members at these points.

The application of shape memory alloys (SMAs) to the seismic response reduction of civil engineering structures has attracted growing interest due to their self-centering feature and excellent fatigue performance. The loading rate dependence of SMAs raises a concern in the seismic analysis of SMA-based devices. However, the implementation of micromechanics-based strain-rate-dependent constitutive models in structural analysis software is rather complicated and computationally demanding. This paper investigates the feasibility of replacing complex rate-dependent models with rate-independent constitutive models for superelastic SMA elements in seismic time-history analysis. Three uniaxial constitutive models for superelastic SMAs, including one rate-dependent thermomechanical model and two rate-independent phenomenological models, are considered in this comparative study. The pros and cons of the three nonlinear constitutive models are also discussed. A parametric study of single-degree-of-freedom systems with different initial periods and strength reduction factors is conducted to examine the effect of the three constitutive models on seismic simulations. Additionally, nonlinear time-history analyses of a three-story prototype steel frame building with special SMA-based damping braces are performed. Two suites of seismic records that correspond to frequent and design basis earthquakes are used as base excitations in the seismic analyses of steel-braced frames. The results of this study show that the rate-independent constitutive models, with their parameters properly tuned to dynamic test data, are able to predict the seismic responses of structures with SMA-based seismic response modification devices.
