  • The framework, described in this paper, involves artificial evolutionary systems that re -produce aimed solutions through a simulated Darwinian evolution process. Through this process the framework designs structures of machines innovatively and emergently especially in the stages of conceptual and basic design. Since the framework simulates the evolution of nature, it inevitably involves processes that converse the natural evolution to the artificial evolution. For the conversion, based on several methods as the building block modeling, Artificial Life, evolutionary computation and the law of natural selection, we propose a series of processes that consists of modeling, evaluation, selection, evolution etc. We have demonstrated the implementation of the framework with the design of multi-step gear systems.

  • This study for development of close-to nature revetment techniques is conducted to rehabilitate disturbed stream ecosystem. For this objective, the experimental reach as on-site dimonstrated research was set up in Hakyoul, the Yangjaech'on from Oct. 1995 to Nov. 1996. Special emphasis on the developing process of the design of revetments was given to geomorphic character of 3 types of low flow channel bank: point bar, attack point and shallow bay. Each revetment was developed with the consideration on revegetation of emergent plants. And designed techniques were applied to the experimental reach, and were evaluated with monitoring for 1 year. As a result of the process, the experiment suggested ecological alternatives to enhance technical feasibility and to replace the conventional river-work.

  • Literacy acquisition is a social phenomenon. Children in a literate society grow up with literacy as an integral part of their personal, familial, and social histories. Because it is language, children learn written language in ways similar to oral language. However. because it is written, the ways in which written language differs from oral language in terms of its different functions and forms affect the way in which children learn written language. Written language is likely to be more decontextualized than spoken language. The ability to use decontextualized language seems to be crucial to successful participation and progress in school. Experiences identified as contributing to preschool children's literacy development contribute to their ability to use language in a decontextualized way. Teale and Sulzby's(1986) metaphor of emergent literacy has provided a conceptual scheme for understanding the nature and process of literacy acquisition in early childhood.

  • The paper is oriented towards a reflection on the epistemological extension of world history. This discipline is currently opening up for new subjects and new foci of interest, with environmental history being one of them. The paper debates the interaction between the global and the local as one of the main issues of world history. It analyses the impacts of the interconnectivity of diverse regions as well as different geographical and cultural complexes, during the period between 1500 and 1800. Assuming that the sea in its economic, cultural and environmental dimensions contributed actively to world history, and is, in itself, a major factor of globalization, the paper intends to highlight interdependencies which fostered connections between the local and the global. It further submits to discussion which was the impact of an on-going globalization process, based on maritime dynamics, on the environment. Through an analysis centered on the impact of European overseas expansion, some environmental impacts will be analyzed. The paper aims at questioning environmental history as an emergent theme of world history, based on the historical experience of connecting worlds developed in the First Global Age (1500-1800).

  • The concrete, practical orientation of the Chinese toward the aim of communal harmony conditioned their approach toward philosophical differences. Ideological conflicts were seen, not only by the politicians but by the intellectuals themselves, to threaten societal well-being. Harmonious interaction was finally more important to these thinkers than abstract issues of who had arrived at the 'truth'. Perhaps the most obvious illustation of the way the Chinese handled their theoretical conflicts is to be found in mutual accommodation of the three emergent traditions of Chinese culture, Confucianism, Taoism and Buddhism. Beginning in the Han dynasty(206 BC-AD 200), the diverse themes inherited from the competing 'hundred schools' of pre-imperial China were harmonized within Confucianism as it ascended to become the state ideology. The harmony among confucianism, Buddhism and Taoism, traditional philosophical trend in China, is very important research subject at contemporary circumstance. For its cultual influences to surrounding nations, such as Korea, japan and Vietnam etc., are so crucial.

  • Furniture design is no exception to human desire for pursuit of the nature. In various design fields, it has turned out nature-decorative method in the past, and also recently it has turned out bio-adaptive method which is more root design process using principal of generation in nature world. The purpose of this study is to analyze application methods and characteristics of fractal geometry and voronoi diagram which are most representative principals of generative design in nature by research on the example of furniture design using these principals. The results of having analyzed fumitures by generative design can be summarized as follows; design principals of fractal; superposition, scaling, repetition & gradation, deformation, distortion and voronoi diagram; individual speciation, variational patten, repetition gradation, ambiguous boundary create new design concept and emergent form in furniture design. Application methods are 'form emergence by algorithm', 'conventional process based on principals of generative design', and 'reproduction of pattern from generative design'. Biological reinterpretations and new explorations of principals of nature generation offer unbounded possibilities for furniture design.

  • Purpose: The purpose of this qualitative study was to describe the essence and the meaning of nurses' experiences of end-of-life care (EOLC) for elderly patients in the long-term care hospitals (LTCHs). Methods: Data were gathered from 12 nurses who had been working at LTCHs in Korea through one-on-one interviews and the data were analyzed by Colaizzi's phenomenological method. Results: The emergent 5 themes were 'Doing the best for protecting patients' life', 'Providing a comfortable dying process for patients', 'Supporting a family's keeping on patient's death', 'Reflecting on life' and 'Desiring for the establishment of a humanity end-of-life care environment'. Conclusion: The end-of-life care for the elderly patients includes supporting elderly patients' comfortable dying process and helping the family keep the death of the elderly. The results indicated that physical facilities and end-of-life nursing capacity should be established in LTCHs for improving the quality of EOLC.

  • The purpose of this study is to compare and analyze the process of hospital visits according to the characteristics of the elderly visiting to emergency medical centers. The subject of study was 571 patients over the age of 65 who agreed to participate in the study of emergency medical centers from May 1 to 31, 2010. The frequency, percentage and ${\chi}^2$ test of collected data were conducted with SPSS WIN 12.0. As a result, the frequency of the aged with or without urgency revisiting emergency rooms due to chronic degenerative diseases was high. In addition, there were many cases that the aged living only with a spouse or remaining single. It was obscure to classify them into a urgent or non-emergent group which made it longer time to visit a hospital. It may be necessary that the care for urgent elderly patients considering the characteristics of the family environment functions to care the elderly were weakened.

  • This study tries to present a new perspective for the coding and coding education. Therefore, this study analyzes coding game as performative writing. First, coding as writing process has the mechanism of serial expansion and circulation by utilizing basic code blocks. And coding as writing process produces a meaning as unit operation that generate an emergent game play. Second, coding as performative writing displays the speaking and writing at the same time and is embodied in game play. Also, absence of failure and correction makes possible users to explore the problem area and to strengthen the problem-solving ability.

  • We investigate the diffusion process of Thomson-scattered line photons in both real space and frequency space through a Monte Carlo approach. The emission source is assumed to be monochromatic and point-like embedded at the center of a free electron region in the form of a sphere and a slab. In the case of a spherical region, the line profiles emergent at a location of Thomson optical depth τTh from the source exhibit the full width of the half maximum σλ ≃ τ1.5Th. In the slab case, we focus on the polarization behavior where the polarization direction flips from the normal direction of the slab to the parallel as the slab optical depth τTh increases from τTh ≪ 1 to τTh ≫ 1. We propose that the polarization flip to the parallel direction to the slab surface in optically thick slabs is attributed to the robustness of the Stokes parameter Q along the vertical axis with respect to the observer's line of sight whereas randomization dominates the remaining region as τTh increases. A brief discussion on the importance of our study is presented.
