  • This research was intended to delve into the diversity of life phenomenon and its characteristics. First of all, this research gave real examples to compare the differences in men's health, disease, and longevity in order to confirm the existence of diversity of life phenomenon. In addition, it also studied the process and mechanism of manifestation of life phenomenon, as well as the influence and problems of existing studies' results and implications. The results are as follow. 1. Differences in health, diseases, and longevity were very big and diverse in researches on different races, nations, ages, socioeconomic status, positions, and even (monozygotic) twins. 2. The basic foundation of all organisms is DNA, and environmental factors change DNA methylation and the structure of chromatin by constantly influencing DNA. Due to this, the manifestation, control, and phenotype of DNA change, resulting in diversified life phenomenon. Therefore, it is the environmental factors, not DNA, that has more influence on the diversity of life. 3. Looking at available studies, the most reasonable perspective on human requires focusing on the diversity of life phenomenon, holistic thinking, and reversible change instead of irreversible determinism. Considerable differences in life phenomenon between entities require a change in malformed perspective on life. Public health and medicine deals with live human beings, a more precise and accurate perspective on life is very important. Because management methods of health and disease, such as structure and approaches of medical research, prevention and cure, must be different by life perspectives.

  • The purpose of this study was to investigate cognition of life phenomenon on robotic dogs according to properties of robotic dogs amongst aged 3, 4 and 5. 95 Children aged 3 to 5 years participated in this study. Each child was interviewed individually and responded to questions designed to measure his/her cognition of life phenomenon. The major findings of this study are as follows. First, there was a significant difference in children's cognition of the life phenomenon according to their age. 3 years were more likely to refer the robotic dog as alive, compared to the 5 years. Secondly there was a significant difference in children's inference of the life phenomenon according to properties of robotic dogs. Such as high activeness and responsiveness, preschoolers considered robotic dogs to be alive and have more biological and psychological traits. This result shows the activeness and responsiveness of robotic dogs influences young children's inference of life phenomenon.

  • The purpose of this study was to examine the views of elementary students and teachers in relation to life phenomenon. Students seemed to strongly agree with the notion of vitalism as well as with organicism. However they clearly disagreed with the notion of mechanism. Contrary to our supposition, their viewpoints on lift phenomenon were highly affected by their relative levels of academic achievement in science subject areas, rather than by their religious affiliations. One possible explanation for this outcome is that elementary schoolers have not firmly established religious views, though they might indeed have a religious affiliation. High-achieving children in science subject areas seemed to agree with both vitalism and organicism (p<.01), and it is suggested that those students must have had more opportunities to encounter related cases in modem science or life ethics. Teachers agreed with all three views, showing the highest rate of approval in organicism. Though they appeared to agree with mechanism, they were strongly opposed to radical mechanism generally arguing that 'organism and machines were essentially the same'. Student responses indicated that TV had a bigger influence on their viewpoint on life phenomenon than teachers did. This means that children held certain views about the relative significance and influences of teachers vis-a-vis TV in daily life, and is also reflective of a perception amongst students that teachers do not how the significance of viewpoints on lift phenomenon.

  • Sheet aluminum alloys have been used in manufacturing of machine structures. In fatigue crack propagation behavior of thin sheet aluminum alloys, it is important that fatigue crack growth rate is affected by crack closure phenomenon. In this work, we analyzed the characteristics of fatigue crack propagation behavior in experiment of constant stress condition for thin sheet Al 2024-T3 alloys, and identified the retardation behavior of crack growth by comparing experimental results of thin and thick plate specimen. We attempt to operate the fatigue life estimating process using the fatigue related material constants from referred fatigue crack propagation analysis. And we analyzed the experimental and prediction results of fatigue life of thin sheet aluminum alloy in order to identify the relation between retardation behavior of fatigue crack growth and crack closure phenomenon.

  • The purpose of this study clarifies an expression characteristic of the phenomenal space. The architecture is an interface between human and nature. Nature presents herself as phenomena. Thus, the phenomenal space should be approached as the essence of architecture that is to accommodate nature. Phenomenon is related to everyday life and shares flow naturally within it. The phenomenon and everyday life form a relationship through the mediating elements that are time, place, and image. If these mediating elements are developed as spatialized elements, time becomes the converse, place becomes the overlap, and shape becomes the revealing. Also, spatial components that are substituted with these elements are void/solid, form, and materials. The relational characteristics of phenomenal space can be identified through these, and such characteristics are one-ness, continuity, and coincidence of opposites. Phenomenal space is expressed with spatial tones and accepted as spatial atmospheres. For the analysis, 15 works of swiss architects were selected to which spatial elements were applied. And It were composed that analysis by arranging these components as the relational network found that expression characteristics. Trough the analysis, It was found that expression characteristics of phenomenal space of the architecture of Swiss architects were prototypicality, primitiveness, and originality. As a results, It is considered that the role of the space that contains the value of everyday life, the value of the phenomenon is necessary.

  • Aging phenomenon is an important issue in Korea national policy. This aging phenomenon depends on the social and environmental characteristics of regions. Also aging phenomenon and regional characteristics have spatial dependency. The purpose of this study is to discover the spatial changes in aging population rate and to find local factors of regional aging phenomenon considering spatial autocorrelation. For spatial analysis of ageing phenomenon, local Moran's I and Geographically Weighted Regression (GWR) were applied. As the results, the most significant changes of aging phenomenon appeared between 2000 and 2005, and most of hot-spot regions (aged regions) were distributed in Jullanam-do and Jullabuk-do. The results of GWR (R-square: 0.681) shows that total fertility rate, the number of doctor per 1,000 people and forest area rate have positive relation with aging population rate, but the number of private academy per 1,000 people has negative relation.

  • This study explored various issues related to the quality-of-life for obese Korean men. In-depth interviews were conducted with thirty men over BMI 25 whose age ranged from 20's to 50's. Projective techniques along with semi-structured interviews were used. The results of interviews were analyzed based on grounded theory. "Stress" was the main phenomenon resulting from the causal conditions of obesity and stigma. Stress consisted of social, psychological, physical and environmental factors. Contextual conditions mediating the relationship between causal conditions and main phenomenon were obesity level, pressure, and public appearance. Avoidance, change of personal traits, and insensitivity were the action/reactions to the main phenomenon. Various factors due to obesity disappeared and quality-of-life increased when they succeed in weight reduction; however, factors related to obesity and lowered condition of quality-of-life continued if they experienced a weight gain/loss yo-yo.
