Recently, there is a new issue, among the contemporary people, for new life style, such as green design and well being. This trend brought up the necessity that there should be alternatives for interior spatial design. In order to catch up with these new issues, the new convenient and environment friendly methods are in need. Space composition using setting-up is skill that can express both the structural aspect and esthetic because it represents traditional beauty into the contemporary age through the structural rigidity and formal beauty. Also the lumber, as main materials for setting up, is in line with well being life style and environment friendliness. The construction of structure by setting-up has advantages in terms of the reuse and the convenience in that the construction of structure is adjustable according to environment. And setting-up has enough plasticity not only because of its own role as linking the objects but also because of being framed by itself. Therefore setting-up will be a design element, if it is expressed outward. Thus, this study aims to give a guide line about how to apply the result from the evaluating that "what is the most suitable setting-up" and "what is the most suitable detail setting-up", based on that structural rigidity, decorativeness and the ease of works. As a result of evaluation, the most excellent types of setting-up in terms of structural rigidity are "Jangbu" and "Panjae" and "Yeongui". The most excellent types of setting-up in terms of decorativeness are "Panjae" and "Yeongui", and the most excellent type of the ease of work is "Mat". And also the most applicable detail setting-up for the utilization of spatial composition is proposed.

To evaluate geology and extent of leachate migration around the landfills, electrical resistivity survey were conducted in area of uncontrolled landfills in Cheonan and Wonju. The Cheonan landfill is located above the paddy fields and the resistivity survey lines were crossed to confirm possible pollution of the paddy fields by leakage of the landfill leachate. In Wonju, the landfill and the downgradient paddy fields are divided by a concrete barrier wall. At the bottom of the landfill, there is a leachate settlement system but has not been in operation. And a total of 4 survey line installed (1 parallel and 3 perpendicular to mean groundwater flow direction). According to the resistivity survey results, the landfill leachate in Cheonan appeared to be restricted only within the interior of the landfill, not to migrate into the subsurface of the paddy fields. These results are well consistent with electrical conductivity values of groundwaters obtained from a periodic analysis of water qualities. In Wonju, however, it was inferred that the leachate emanating from the landfill migrated beneath the abandoned leachate settlement system and it would reach the downgradient paddy field.

Recently, large APT complexes are newly constructed in Taegu city and among them, large APT complexes aggegate densly espically in Weolsung and Jisan complexes of Dalsuh-gu and Susung-gu districts. The purpose of this thesis is to perform occupants' apprasials about residential environment on the housewifes residing at new constructed APT who seem tn have different apprasials on the residential environment by the zones. The results of the investigations are as follows. 1. House possessed type and house sire got elevated in comparison with them before shifting residence in respect to residential property and it was revealed they moved to short distance in the change of their lands. And most occupants could choose their houses by looting-out and there's some difference in the choice motive according to the zones. 2. As a result of studying the relation between demographic and residential properties, there were deep differe-nces in the Possessed house type before move, possessed house size after move, preferenti-al degree of house and move plan. 3. In the degree of satisfaction on residential environment, the result was high in the order of heating facilities, water-supply and draining facilities and lighting and was low in the order of room's size, interior decoration and soundproofin. According to zones, there was a great difference in the items of room's size, privacy, heating facilities, securi-ty from calamity, ventilation, convenience of traffic and school group and facilities for extracurricular activities and the degree of satisfaction was high in Jisan zone in othe items except for room's size and heating facilities. 4. In the tenants' apprasials on tile inside and outside spaces of the zones, important factors were "Cultural Institutions", "Green Areas", "Level of Welfare Facilities" and "Utility degree of welfare facilities" and in the classification of important factors according to the zones, the first and the third factors were changed each other. I think this is because they attached importance to somethings dissatisfied in present circumstances.

The present study is following a series of research investigations on design resources coming from collected data referring to users' awareness and preferences. The aim of this research is to test the Healthcare Environmental Color Index as a basis for practitioners in the field of healthcare design. An array of color samples selected from previous research, have been presented to the respondents via an online survey, in order to identify the preferences of the two groups on the relation between environmental color and health. As a result of the first experiment and through the comparison of processed data, the maximum percentage of respondents from each group is validating the relation between environmental color and health. For the second experiment we intend to highlight the patterns of color preferences for each group, and thus to test the color samples healing function. The compared data also showed a higher awareness of Koreans than Romanians on the potential of color applied to healing environment. Last but not least in the third experiment we show the top five color samples preferred by each group. It is significant that the comparison of the results validated once more some of our previous findings related to the healthcare environment, such as: the general preference for the green hue (associated to fatigue relax according to color psychology) and the blue hue (sedation release effect) but also the yellow hue - associated to bright energy. Three out of the top five preferred color samples have been identical to both groups while the other two samples have shown characteristic variations. These results show that similarities are strong and can be used in a glocal design strategy as an accessible tool for any practitioner. Based on the Healthcare Environmental Color Index and users' preferences analysis, a new design culture for healthcare can be established and developed.

It's been more than 30 years since global warming by the increase in CO2 became a cause celebre worldwide. Recently the government promulgated Framework Act on on Low-Carbon Green Growth and has been continuously putting much effort into saving energy and reducing carbon dioxide emissions such as an international climate change conference to prevent the increase in CO2. However, because most cities are not planned for energy saving, new cities should be planned as the active energy-efficient urban structure for 'sustainable urban development' from a long-term perspective. This study aims to design a new prototype for the sustainable energy-independent and environment-friendly housing estates which is the nation's new vision in the era of the Fourth Industrial Revolution. A study on the energy-independent site planning and the quantitative standardization of its factor will be conducted.

Background and objective: With the revision of the Act on Urban Parks, Green Areas, Etc. in 2013, the "urban agricultural park" was newly established under the subcategory of "themed park," thereby establishing the institutional basis for the creation of urban agricultural parks. However, urban agricultural parks are still in the early stages of their introduction. There is a lack of research on direction setting and specific operation management that considers urban residents' needs and the city's physical infrastructure. Methods: We utilized the public service design process suggested by the Ministry of the Interior and Safety of the Republic of Korea in 2019 to identify problems and develop directions for urban agricultural parks. The process consisted of the following four steps: Understanding, Discovering people's needs, Defining real problems, and Developing ideas. Results: As four types of ideas for revitalizing urban agricultural parks, 'information users want to know,' 'user participation in design,' 'venue for local communities,' and 'urban agricultural parks as health and rest areas' were derived. This means that urban agricultural parks must provide the information users want; users must plan, decide, and implement such information by directly participating in the creation and efficient management and operation of urban agricultural parks; and urban agricultural parks must be used as a venue for local communities. Urban agricultural parks should also be spaces for health and relaxation. Conclusion: Urban agricultural parks should avoid the unified space and passive participation patterns of existing urban parks, and become real spaces for resident participation that can satisfy all the production, leisure, landscape, ecology, and psycho-social needs of the users of urban agricultural parks. Furthermore, it is necessary to introduce a more systematic and diverse operating system so that it can work to revitalize the local community and connect organically with the function of the city.

In paste backfill mining, cemented coal gangue-fly ash backfill (CGFB) can effectively utilize coal-based solid waste, such as gangue, to control surface subsidence. However, given the pressurized water accumulation environment in goafs, CGFB is subject to coupling effects from water pressure and chloride ions. Therefore, studying the influence of pressurized water on the chlorine salt erosion of CGFB to ensure green mining safety is important. In this study, CGFB samples were soaked in a chloride salt solution at different pressures (0, 0.5, 1.5, and 3.0 MPa) to investigate the chloride ion transport characteristics, hydration products, micromorphology, pore characteristics, and mechanical properties of CGFB. Water pressure was found to promote chloride ion transfer to the CGFB interior and the material hydration reaction; enhance the internal CGFB pore structure, penetration depth, and chloride ion content; and fill the pores between the material to reduce its porosity. Furthermore, the CGFB peak uniaxial compression strain gradually decreased with increasing soaking pressure, whereas the uniaxial compressive strength first increased and then decreased. The resulting effects on the stability of the CGFB solid-phase hydration products can change the overall CGFB mechanical properties. These findings are significant for further improving the adaptability of CGFB for coal mine engineering.
