The purpose of this study is to suggest an environment-friendly design method of ecological architecture complex, with the reference to foreign cases. The ecological architecture is very similar to the natural ecosystem, but there is increasing international scientific consensus that human activities are having a discernable effect on the global climate. The most important thing is keep going harmoniously between preservation and development relevant with nature. In the process of ecological approaching concept, we need a method that from "architecture in a nature" to "architecture as one section of the nature" would be extended further, also the purpose of this study aims to achieve these kinds of ecological architecture. As a result of, in this Age of industrial science, we are proposing useful materials and suggestion regarding the ecological architecture planning of Korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

As the preservation law of soil environment has reinforced, several soil remediation projects have been performing for railroad sites. One of the main sources of soil contamination is the leakage of diesel from locomotives or underground storage tank. Also, the lubricant used to maintain turnouts causes railroad soil contamination. The purpose of this study was to develop the analysis and the remediation method for lubricant-contaminated soil. The lubricant in the contaminated soil was analyzed qualitatively and quantitatively by TLC (Thin Layer Chromatography) and GC (Gas Chromatography), respectively. The organic pollutants were removed from the soil using microorganisms degrading lubricant. Hereafter it will be necessary to apply this bioremediation method in the railroad field.

The energy conservation in buildings affects environmental preservation as well as economic benefits, and creates the comfortable indoor environment set for the inhabitants. Especially, apartment buildings show ever-increasing energy consumption with large-sized and high-class tendency, thus energy saving counterplans are needed. The present study is to develop an optical control algorithm by using heating load curve according to the outdoor temperature change. Heating load analysis should be performed before the present method can be applied. Dynamic heating load simulations are performed by resistance-capacitance method. Results show that heating load decrease linearly according to the increase of outdoor temperature.

To compare the quality of ultrastructural preservation of Scanning Electron Microscopic specimens dried with different methods; pure air-drying, air-drying with using Tetramethylsilane(TMS), four kind of air-drying using Hexamethyldisilazane(HMDS) and critical point drying(CPD), we conducted scanning electron microscopic observation on liver, skeletal muscle and intestinal tissues from laboratory rat treated with each method. In pure air drying group, severe distortion of tissue surface was observed, and in HMDS treated group, only liver tissue showed slight distortion. But in TMS treated group, each tissue showed a good presentation comparable to CPD group. The results suggest that the method of air-drying using TMS may be the former is less expensive and simple be and also time-saving.

As the antioxidant and free radical scavenger, glutathione (GSH) participates in the preservation of cellular redox status and defense against reactive oxygen species and xenobiotics. Glutamate-cysteine ligase (GCL; also known as ${\gamma}$-glutamylcysteine synthetase, EC 6.3.2.2) is the rate limiting enzyme in GSH synthesis. In the present study, the accurate method for determination of GCL activity in crude liver extracts was developed by measuring both ${\gamma}$-glutamylcysteine and GSH from cysteine in the presence of glutamate, glycine and an ATP-generating system. We added glycine to promote the conversion of ${\gamma}$-glutamylcysteine to GSH, and to minimize the possibility of ${\gamma}$-glutamylcysteine metabolism to cysteine and oxoproline by ${\gamma}$-glutamylcyclotransferase. We established optimal conditions and substrate concentrations for the enzyme assay, and verified that inhibition of GCL by GSH did not interfere with this assay. Therefore, this assay of hepatic GCL under optimal conditions could provide a more accurate measurement of this enzyme activity in the crude liver extracts.

Aims: This study was designed to describe the personal life experiences of breast cancer survivors regarding their efforts to recover and preserve their health in Taiwan. Method: The study utilized a qualitative research method, wherein purposive sampling, one-on-one, face-to-face, in-depth semi-structured interviews were conducted. The data were then analyzed using content analysis. Data were saturated after interviewing 15 cancer survivors. Results: Three common themes emerged: introspection on the cause of the cancer, realization of a harmonized lifestyle, and reflecting on the strong will to survive. Conclusions: These findings are helpful in understanding the relationship between breast cancer survival and individual efforts to restore and preserve health.

It is important to estimate the capability for the facilities and the condition of schools continually and correctly because the structure's life is remained more longer through the effective building control and preservation. In accordance with above of that, it is required to understand the knowledge about all matters at the stage of management for educational facilities and establish the procedure of the facility management consistently. This research suggests the method, which remains consistent and objective and deals with the total functional degree by following ㄴthe way to systemize the management plan of the facility estimation. The functional estimation of the existing facilities will be useful to make an plan for repair, maintain and checking of them as well as be the standard for remodeling and the educational facility duration, including long period project for building mending.

The project of Construction of Siem Reap bypass road in Cambodia consists of alignment improvement of existing route, extension of width of road and laterite paving. This project is carried out by fast-track method on the design and construction for bypass road of 15.2 km length and 8m width for five months. Though some difficulties for the construction works such as the location of borrow pit and rock source, rainy seasons etc, the construction could be completed successfully owing to the cooperation of related authorities, company and residents. This 2 way Angkor detouring road will function as industrial roads in Siemreap region. These new two roads will not only bring better logistics requirements and safety, but also impact to poverty alleviation and preservation the beauty of the ecological environment of Angkor region. The basic information related to geotechnical engineering of this project is introduced.

Appling natural light to the spaces for the exhibition requires the compromises between the expectations of visitors whom are preferable to perceive the details of the works of art, and preservation of light sensitive artworks of least exposure to light. To solve the compromises, it requires a careful planing to control the penetration of the daylight by physical and mechanical devices such as diffusive glasses and blinds. The control of light penetration can also be achieved by providing spaces inside and outside of the building. The aim of this study is suggest the conceptual methods to control the daylight by space design. Museums and galleries using daylight were investigated how the daylight is controlled by the integrated spaces in the exhibition spaces. This study presents nine ways of controlling daylight penetration by space design.

Life nurturing medicine mentioned in this paper refers to medical practice based on health preservation. This practice embraces alimentotherapy, respiration practice, qi gong, lacking food method as well as preventive medicine and geriatrics based on this theory. This life nurturing practice are noticeable through korean history. There were Korea own's xianjia(仙家) yangseng practice which after the transmission of Taoistic yangseng, it has been developed to take a field in medicine. The first publication that proofs this unification of life nurturing practice and medicine is Donguibogam ("東醫寶鑑"). Life nurturing method took more proportion in medical practice as medical books emphasized on preventive medicine like Yiyangpyun("二養編"), Boyangji were published distinguishing from other field of medicine.
