This thesis has purpose of explaining that light is not only appreciated but also physically percepted in contemporary space design and examining effects of space experience through the physical perception. In keeping with such developments, light has been perceived as the object of another architectural tool in modern space design and has provided men with new experience by providing space image and function different from previous ones. With the expansion of the area of light, light has changed a space that is not a simple architectural factor into the essential concept that gives the architectural space image ! by combining it with architectural space, structure, form and materials throughout the whole process from the beginning to the completion. Through phenomenological approach, light is percepted and experienced by body movement, intervention of senses and memories, and passing of time. The percepted and experienced light brings increase of mutual understanding in space, activation and continuance of user's sensation, recreational experience by event occurrence and space experience effect thorough information from media.

In this study low cycle fatigue (LCF) behavior of 12Cr steel at high temperature are described. Secondly, comparisons between predicted lives and experimental lives are made for the several sample life prediction models. Two minute hold period in either tension or compression reduce the number of cycles to failure by about a factor of two. Twenty minute hold periods in compression lead to shorter lives than 2 minute hold periods in compression. Experiments showed that life predictions from classical phenomenological models have limitations. More LCF experiments should be pursued to gain understanding of the physical damage mechanisms and to allow the development of physically-based models which can enhance the accuracy of the predictions of components. From a design point-of-view, life prediction has been judged acceptable for these particular loading conditions but extrapolations to thermo-mechanical fatigue loading, for example, require more sophisticated models including physical damage mechanisms.

This study explored and described the living spiritual experience and was attempted to gain an understanding of spirituality. This was done by eliciting participants′ verbal descriptions of their experiences. Method: Data was obtained from in-depth interviews with one cancer patient, one pastor, and three missionaries after obtaining informed consent from each. Interviews were tape recorded and transcribed verbatim. The transcripts were analyzed using Colaizzi′s phenomenological method. Sandelowski′s evaluation criteria for qualitative research, such as reliability, suitability and auditability, were also used to establish reliability and validity of this study. Result: The five major theme clusters that designated the essence of the spiritual experience, "spiritual awareness," "interconnectedness," "love," "tran- scendent energy," "purpose and meaning in life," emerged from the analysis. Conclusion: This study revealed that spirituality was activated by awareness through introspection and interconnectedness with a Supreme Being. The interconnectedness with a Supreme Being played an important role in harmonious relationships with others and self. It also resulted in revealing the other beneticial attributes of spirituality. Love, the core concept of the interconnectedness, worked as a transcendent energy. Also, the ability to see beyond reality and resulted in finding meaning in life and accomplishing well being.

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.

Purpose: The purpose of this study was to describe the pregnancy and childbirth experience of unmarried teenage mothers and to provide basic information of programmes to prevent unplanned pregnancies in unmarried teenage mothers. Methods: The participants of study were 7 unmarried teenage mothers who lived in shelters in D city, and whose ages ranged from 15 to 19 years. Data gathering through in-depth interviews, 3 to 5 times, was done from August 2002 to September 2003. Data were analyzed with Colaizzi's(1978) phenomenological methodology. Results: The implications of pregnancy and childbirth experience for unmarried teenage mothers were "Seem to live in hell", "Desire for a miscarriage", "Lethargy", "Feel maternity", "Feel unjustified", and "Change of sexual perception". Conclusion: These findings contribute to understanding the pregnancy and childbirth experience of unmarried teenage mothers and can be used as sexual education information to help unmarried teenage mothers to prevent further unplanned pregnancies.

The performance of turbo pump drops rapidly and it gets into break-down when the void fraction reaches above the threshold value because the impeller flow passage is choked up with air bubbles. Phenomenological understanding of break-down and pumping recovery mechanisms under air-water two-phase flow conditions are therefore important for pump designers and essential assignment for researchers. In this paper, we investigated the characteristics of break-down and pumping recovery due to entrained air occurring inside a screw-type centrifugal pump which has a wide flow passage mainly through the findings of suction and discharge pressures, rotational speed, flow rate measurements and visualization.

Fatigue crack propagation of duplex stainless steel weldments was studied to develop further phenomenological understanding of the influences of welding heat cycle accompanying microstructural changes. Fatigue tests were carried out under constant amplitude of load in air at room temperature. The results showed that the crack propagation rate was different in base metal, heat affected zone and welding line. The crack propagation behavior in each part of duplex stainless steel was strongly dependent on phase ratio(.gamma../.alpha.) and several factors of microstructure also affected this propagation behavior. The fractographic feature in each part of steel were discussed on crack propagation behaviors.

This paper focuses on Wajiro Kon (1888-1973) and his architectural efforts on theorizing Korean minka in the early 1920s. Wajiro Kon's unique phenomenological approach, so different from the positivistic analyses of his contemporaries, evident in his meticulous sketches and vivid descriptions, helped him theorize how the craft-oriented architectural development of Korean minka were shaped by people's everyday lives. In particular, he found that ondol had developed in various and complex ways, creating differences between the northern and southern Korean regions. Moreover, Kon identified the practical improvements in Korean minka made by inventive, creative people. However, the paper demonstrates that in this process, the new understanding retained the dual perspective of Korean minka as not only environmentally formulated, craft-oriented artifacts but also as re-formed objects that should be improved through an interplay with external factors.
