Creep phenomenon affects the stability and integrity of concrete structures. An inaccurate prediction of these strains may lead to the appearance of cracks and excessive deflections which may cause in some cases the demolition of structures. In fact, the measured values of these uncontrolled strains appear often to be clearly different and larger than the expected ones. Therefore, an accurate prediction of concrete deformations is a necessity. As a matter of fact, the codified descriptions of this phenomenon are unreliable and don't consider the effect of admixtures. The physical nature of creep is not well understood and almost all creep models are mainly of empirical nature. To overcome this issue, a study of the correlation between different parameters affecting concrete creep is performed and a new model for predicting creep of concrete is elaborated. This new model considers the effect of admixtures, specifically the silica fume, in predicting concrete creep and allows an accurate prediction of this phenomenon. The proposed model is based on the observation of physical behavior of creep phenomenon. It targets at expressing creep compliance in terms of structural and environmental parameters. In fact, the experimental observations show that creep curves follow two kinetic regimes leading to a model called Phenomenological Creep Model. By adequate regressions and substitutions, and according to this model, we can express creep compliance in terms of structural, environmental parameters and admixture types and percentage. The proposed new Phenomenological Creep Model Silica Fume (PCM19SF) calculates accurately creep of concrete by considering the effect of silica fume.

This study was conducted to grasp the progress of the health management program in small scale industries with phenomenological approach. The industrial health care system compose of manpower, devices, and facilities such as medical resources, organization, service delivery system, financial resources, payments, and management system is important for the industrial health. Especially health management program should be provided feasible conditions to workers. The data collection period was 2 months from September 1 to October 30, 1997. The indepth interview results for health monitor, labors, and occupational health nurses were analyzed by Giorgis' phenomenological method. The major results were as follows: 1. The workers, health monitors and nurses felt that the subsidiary program of health management in small scale industries were necessary. This project for small-size industry can be set-up through complementary education for health monitors and resolvement of nurses' six suggestions. It is necessary to provide followings ; 1) Properly devision of industry 2) More clear guidance for health management at visiting time 3) Legitimate incentive system 4) Health education materials and devices 5) Change of fee and material payments at visiting 6) Budgets and system for medication and vaccination at visiting 2. Above all, it is suggested that the strategics of the health management program should be developed.

Since last several decades, iconic memory has been accepted theoretically valid for its role of the first storage mechanism in visual memory process. However, there have been relatively less interests in iconic memory among researchers than their interests in visual short- and long-term memory. Such little interests seem to arise from a lack of detailed understandings of theories and methodologies about iconic memory and visual persistence. This study aimed to achieve the understandings by reviewing theories and empirical studies of iconic memory and visual persistence. The study further discussed future direction of iconic memory research according to the essential aspects of phenomenological and ecological criticisms against the validity of iconic memory.

The purpose of this study is to investigate the nature of work-family compatibility in the everyday experiences of dual-earner families. By comprehensively describing how dual-earner families manage daily life, this study shows their current situations. In particular, this study overcomes the limitations of previous studies using the phenomenological research methods. Previous studies partially dealt with the problems of dual-earner couples, such as the role conflict of wives and husbands. However, this study broadly demonstrates how wives and husbands as independent individuals manage their lives by working together for a living. Participants were 6 males and 6 females, who lived in Gwangju metropolitan city. Data were collected through in-depth interviews and analyzed using the method of Stevick-Colaizzi-Keen in Moustakas (1994). The results of this study display that dual-earner couples work for a living, but work is the driving force in their life. Family provides dual-earner couples with a stable life, but their stable life is possible by social support like the assistance of a mother-in-law. Dual-earner couples consider work and family as the essential axis of life, thus they give the same value on work and family. Even though dual-earner couples have a difficult time educating their children because of long working hours and coming home late, they positively combine work and family meeting the needs of self-improvement. Therefore, it is necessary to create a working environment that provides enough time for housework and childcare.

This study is a qualitative study using phenomenological methods that focus on the meaning of what individuals experience to understand the meaning of the gender role of women after childbirth. The participants of this study are 17 women who gave a birth from 8 weeks of the postpartum period to a year after the birth. Seven categories were derived from the results of analyzing the meaning of the gender roles of participants, and the seven categories are confirmed to be body changes and pain, just making me feel down, the difference between expectation and reality, isolation from husband and social network, thinking about my mother as a woman, the pain of body and mind sublimates, and convergence/dissociation between femininity and motherhood. This study is meaningful in that the results of this study provided information that would have a broader understanding of women's gender role after giving birth.

The aim of this study was to explore and understand the communication experiences of the deaf, from their perspective. This study obtained informations through in-depth interviews with five people with deafness using sign language. The collected data was analyzed according to Giorgi's phenomenological qualitative methods. The following main themes were extracted from the practical experiences of the participants interviewed: 'being confined in the world without sound by themselves', 'learning and comprehending how to communicate', and 'looking for identity as a membership of the deaf community'. Sign language was a tool and mediator so that they could come out of their comfort zone, communicate with people, and connect to others in the deaf community. However, on the other hand, sign language had a contradictory role that restricted their activities to the deaf societies that could understand each other using sign language. As a result of this study, we can be cognizant of how much not hearing and speaking(hearing disability) is a difficulty for human beings. The implication of this study's results on policy making and actual practices are discussed focusing on the rights and well-being of the deaf.
