This paper describe the performance of seawater purification, to which living organisms can adapt, and the physical properties of porous concrete with continuous void. Although conventional concrete has been regarded as a destroyer of nature, seawater and air can pass freely through concrete when it is made porous by forming continuous void. This not only enables plants to vegetables, but also makes it possible for microscopic animals and plants, including bacteria, to attach to and inhabit uneven surface as well as internal voids when the concrete is provided in a natural seawater area or seawater side area. As a result, porous concrete using recycled aggregate improved the performance of seawater purification. In this study, The performance of seawater purification of porous concrete using recycled aggregate analyzed by T-P, T-N.

This paper discussed community ecological approach for Environmentally Sound and Sustainable Development(ESSD) and Sustainable Society(SS). Community ecology is composed of nature, environment and diverse species and is dynamic and sustainable system by interaction among those components. It is required long-term, integrating and eco-centric stances to achieve ESSD and SS such as eco-city and eco-village movements. This is integrated and complicated perspective beyond traditional dichotomy between human and environment. Community ecological perspective directs people toward ecological society system which creates and maintains adaptable life style under ecological situation in community. Building up eco-parts, eco-cites, eco-villages are crucial movements for promoting human's environmental living standards. These sustainable community movements require people to change their values and life styles suitable for their SS. It is required integrated and balanced perspective and participating endeavor of residents to maintain SS.

As chemistry dyes has considerably developed with industrial society, natural dyeing has gone out of people's head for a long time. But the serious problems from environmental pollutions and ecological damages make people look far Well-being. Natural dyeing also has concentrated again and the interests about it are growing larger and larger. Well-being that a modern person pursues and a Natural dyeing walk along a same string of connection. That is, people want their life to change from quantity matters into qualities. The relations of the natural dying which has the color of nature and Well-being phenomenons are analyzed through dissertations and references. The study about the correlations between natural dying and well-being shows that many advantages of natural dyestuff and the effects of dyestuff are definitely needed to people living in modern times. Also for the protection of an ecosystem, rapid popularization and the development of new design is completely required.

Objectives : Hakomi therapy is a body-centered psychotherapy established by Ron Kurtz in the 80s. Here we introduce the clinical possibilities of application in Korean medicine through Hakomi therapy. Methods : At first, we present the definition, basic principles, terms and outline of Hakomi therapy in reference to "Body-centered psychotherapy The Hakomi Method," published by Ron Kurtz. Then we study the clinical application of Hakomi therapy on Korean medicine. Results : There are many similarities between Hakomi and Korean medicine, such as Mind-Body holism, organicity through homeostasis of living things, non-violent attitude of therapist like Tao, and emphasis on breathing by corresponding with Nature. Also, there are similarities in methods, such as Ohjisangseung, Iijungbyunqi, and Qigong. Hence, Hakomi therapy can be useful in Korean psychotherapy. Conclusions : If we can graft Hakomi therapy onto Korean psychotherapy, it will be efficacious for Korean psychotherapy to be systematized.

Recently, the concern for the environmental noise has increased due to the growing of the living standard. The environmental noise regulations based on the equivalent noise level are widely used. However, the noise level, which Is based mainly on the magnitude with A-weighting, the important characteristics of noises in frequency and time domains and the impulsive nature cannot be assessed properly. These can have substantial effects on how human respond to noise. Therefore, the noise evaluation methodology based on the sound quality rather than the equivalent noise level can be more suitable to represent human response to the environmental noise. This paper describes the study on environmental noise quality analysis for various noises. A cluster analysis was carried out and the noises were classified into several clusters using the values of sound quality metrics. The classification was confirmed by comparing time and frequency characteristics of the noises. And then the result of Jury testing was analysis.

This research has been carried out to give economical incentives and to promote for the eco-friendly village. A standard model plan for the Korean eco-village has been prepared by systematically applying the results of the research to Boksoo village, which served as an exemplary model. Plans for promoting the Korean eco-village are finally derived after a series of theoretical assessment of conceptual propositions in harnessing natural elements well suited with man-made structures. The eco-friendly village that this study is to develop harnesses natural energy resources and establishes pleasant living environment for human. It minimizes the unjust load against nature and restrains the excessive consumption of irreplaceable indigenous energy and other natural resources on earth. Paraphrasing, the utilization of natural energy resources in the eco-friendly village features various schemes of the related technologies in energy conservation and exploitation of renewable energies including solar thermal, photovoltaic, daylighting, wind power and etc. The eco-friendly village would definitely make our world more healthier than before by suppressing the emission of green house gases from fossil fuels and ever increasing energy consumption.

The purpose of this research was to develop evaluation index of regional development for producing potential values of rural regions besides agriculture on a commercial scale. Rural regions have potential values such as preserved nature and spatial advantages and so on. For regional development, potential values should be synthetically evaluated by objective and standard index for supporting decision. For evaluation of plural functions of rural regions, evaluation index of rural regions was developed based on rural amenity. Applicability of evaluation index was studied using GIS and natural break method.

Generating fractal images by graphing calculators such as TI_92 combines several important features, which convey the excitement of a living, changing mathematics appropriate to secondary or post-secondary students. The topic of fractal geometry can be illustrated using natural objects such as snowflakes, leaves and ferns. These complex and natural forms are often striking fantastic and beautiful. The examples highlight the fact that complex, natural behaviors can result from simple mathematical rules such as those embodied in iterated function systems(IFS). The visual splendor beauty of fractals, in concert with their ubiquity in nature, revels the intellectual beauty of nonlinear mathematics in a compelling way. The window is now open for students to experience and explore some of the wonder of fractal geometry.

Globalization, unpredictable markets, increased products customization and frequent changes in products, production technologies and machining systems have become a complexity in today's manufacturing environment. One key strategy for coping with the evolution of this situation is to develop or apply an enable technology such as intelligent manufacturing. Intelligent manufacturing system (IMS) is characterized by decentralized, distributed, networked compositions of heterogeneous and autonomous systems. The model of IMS is inherited from the organization of the living systems in biology and nature so that the manufacturing system has the advanced characteristics inspired from biology such as self-adaptation, self-diagnosis, and selfhealing. To prove this concept, an innovative system with applying the advanced information and communication technology such as internet of things, cognitive agent are proposed to integrate, organize and allocate the machining resources. Innovative system is essential for modern machining system to flexibly and quickly adapt to new challenges of manufacturing environment.

Recently, as the interest of the government and the public on energy saving has increased, the airtightness of buildings has been improved to improve the insulation performance of buildings. However, indoor air pollution due to increase of pollution source in indoor space and lack of ventilation is increasing and interest in indoor air quality is increasing. In 2003, the Ministry of Environment enacted and promulgated the Act on Indoor Air Quality Control in Multi-use Facilities. Radon is a naturally occurring radioactive inert gas with colorless, tasteless and odorless nature. The concentration is high in a room where radon can not escape. Although lononggas is naturally occurring, it is not interested in living environment, but it is easily inhaled through human body through respiration and causes lung cancer in long-term exposure. Therefore, this study intends to carry out an experiment for the reduction of radon gas, which is the first carcinogen in indoor air pollution sources.
