This is the study about the New Formation Developement, the Changeable Table Design with Units that made of Wasted Wood to use restricted material rationally and to improve the space efficiency in the Table Design. We made some changeable table design with units that made of laminated wood wasted. And we found out the following formative characteristic and physical merits through this study. First, the space efficiency can be improve technically through the unit combination and organic transfomation of the specific form and a new method by laminated wood make the personal originality and the structral stability be built up. Second, there are some merits, moveable convenience and variable layout by the combination or transformation or personal fondness so that economical efficiency and variable of design can be improved. Third, we can remove original faults inside wood like a knot or not-uniform of wood organ when we laminate wood so that we use proper units that have original beauty of wood and can represent mild mood of furniture wholly. Fourth, much more strengthen tensile strength by the reciprocal action among the units that be made of laminated wood reduces wood's metamorphosis like bending or twisting so that the uniformity of wood can be gain and furniture's metamorphosis can be reduced. According to changes of nature environment, the difficulty of supply and demand for wood may be happen. According to changes of life style these days, supply and demand for environment friendly material, processing technique and developement of design to improve the efficiency of using space must be very important factor in morden furniture design. So we propose changeable furniture design by using new environment friendly meterial and processing method from this study.

Distributed models represent watersheds using a network of numerous, uniform calculation units to provide spatially detailed and consistent evaluations across the watershed. However, these models have a disadvantage in general requiring a high computing cost. Semi-distributed models, on the other hand, delineate watersheds using a simplified network of non-uniform calculation units requiring a much lower computing cost than distributed models. Employing a simplified network of non-uniform units, however, semi-distributed models cannot but have limitations in spatially-consistent simulations of hydrogeochemical processes and are often not favoured for such a task as identifying critical source areas within a watershed. Aiming to overcome these shortcomings of both groups of models, a hybrid watershed model STREAM (Spatio-Temporal River-basin Ecohydrology Analysis Model) was developed in this study. Like a distributed model, STREAM divides a watershed into square grid cells of a same size each of which may have a different set of hydrogeochemical parameters reflecting the spatial heterogeneity. Like many semi-distributed models, STREAM groups individual cells of similar hydrogeochemical properties into representative cells for which real computations of the model are carried out. With this hybrid structure, STREAM requires a relatively small computational cost although it still keeps the critical advantage of distributed models.

With the sustainable development theory introduced, some planning factors, such as how to minimize bad effects on the environment and how to be more environmentally friendly, have been Integrated in planning the residential development. In addition, a new residential space concept, the ubiquitous home, arouse the interest of architects and residents. Although there have been many efforts to achieve the environment-friendly and convenient residence, the problem is that the environment-friendly architecture's many of the efforts have been primarily focused on the outside of the apartment units. Thus, the purpose of this study is to show possibilities of housing model not only being applied the environment-friendly construction concept to the inside of the apartment units, but also being integrated the ubiquitous home model inside.

The purpose of this research is to suggest design direction about common space of small sized residential units for elderly housing in order to construct desirable residential environment. This research examines spatial composition and the residents' behaviors in three different types of residential units at intervals of five minutes from 9:00 a.m. to 19:00 p.m.; and analyzes the characteristics of spatial use. The following is the result. The using rate of common space is influenced by the atmosphere of residential units more than healthy condition of the elderly; furthermore, the frequency of usage is also increasing highly as mush as forming the lively atmosphere. In order to form the animated residential environment, it is necessary to provide to various activities, such as cooking, eating, watching TV, leisure, hobby, rest, etc; and the space must plan encouraging relationship with other people. Moreover, it is required to consider to each of personal characteristics ingeniously, and manage to programs extending their durability in common space of elderly housing.

An evaluation of the environments in the wandering pathway of the dementia units was carried out. It is revealed that the quality of the environment for the wandering pathway of the sample units was very low. In particular, lacks of social environments in Unit-B and Unit-C, and lacks of orientation aids in all the sample units were shown. Therefore, re-design for the wandering pathway of the sample units is needed. Recommendations for improving the wandering pathway and having appropriate wandering pathway without any abrupt change in existing layout of the sample units were suggested, and the limits of this research is diagnosed. It is also shown that since evaluation categories used in this paper had very closed relationship each other, those evaluation categories can be used in other settings.

With its rapid modernization and unparalleled speed of aging, South Korea faces the need for dramatic increase in its supply of nursing homes. Among the spacial components of nursing homes, residential units are considered as an essential part because the older person in nursing homes usually spend most of their time in residential units and the nursing homes are mainly composed of various residential units. It is necessary, therefore, to prepare a guideline for the plan of residential units in order to design the healthy and efficient nursing homes. This paper has first identified the concept of residential unit and analyzed 66 cases in the 62 nursing homes from 4 countries. And 4 nursing homes in Korea have been surveyed for the in-depth study. On the basis of this analysis, architectural prototypes of residential units have been proposed and the architectural characteristics of them have been compared analytically.

This study aims to consider interrelations and reasonability to inquiry elements of environment units in 10th Science textbooks of 7th curriculum on the basis of their inquiry contexts, processes and activities. Frequency of inquiry contexts is 59.9% of the highest value in natural environment context but is 4.0% of the lowest one in techno-industrial context. Measurements, inferences, predictions, experiments, data-interpretations, correlations, conclusionreveals in inquiries are in all the textbooks, but observations and classifications, hypothesis generations, controlling variables, experimental designs and generalizations are not in some textbooks. Discussions, experiments, investigations in inquiry activities are included in all the textbooks. However, inspections are not appeared in the all the books. Based on the above results, social and techno-industrial inquiry contexts in the varied scopes are necessary in the environment curricula with a unified direction. Inquiry processes with pro-environmental behaviors as a last goal might be given into the curricula, having tasks that could be understand unified inquiries. In addition, inspections with effectiveness might be thrown into the scene of education.

To investigate the effect of on-site bioremediation in soil that have been contaminated by hydrocarbon fuel spills, petroleum-degrading bacteria isolated from soil around petroleum chemical industry and microbial agents were constructed. We investigated biopiles for on-site bioremediation of soil contaminated (5000 mg per kg) with bunker A fuel in five independent lab-scale experiments. Five biopile units constituting the following treatments: (1) control with no nutrients and microbial agents (2) microbial agent M plus nutrients (3) microbial agent C plus nutrients (4) only microbial agent C (5) control with only nutrients. The results were highly different one another. After 30 days in treatments with optimal condition, total petroleum hydrocarbons were reduced to below 10 mg per kg of soil at the biopile units mixed with microbial agents, but control biopile units show that were reduced from 1,105 to 2,588 mg per kg of soil. Our results show that microbial agents at on-site bioremediation of fuel-contaminated soil is highly effective.
