This study purports to investigate the status quo of the environmentally-friendly green healthcare in teaching hospitals through the questionnaire survey. Data were collected from a total of 46 hospitals. The survey results revealed that most teaching hospitals did not meet the global standard of environmentally-friendly green hospitals. Especially, such items as alternative energy system, water recycling, CO2 emission reduction, green building construction, installation of pond or spring were found to be significantly below global standard. Based upon the study results, various strategies for establishing green hospitals were discussed. For example, energy saving design, such as solar heating, natural wind cooling, automatic temperature controller, green material use, wall surrounded by ivy, were recommended. In conclusion, the strategy and evaluation tool developed in the study will provide a good guide for establishing environmentally-friendly green hospitals.

This design was submitted to an invited competition for the Ski Resort of Kangwon Land which was held by Kangwon Land Resort in August, 2003. The site is located at 1∼17 Gohan-ri Gohan-eup Jungsungun Kangwon-do and has an area of 5,000,000$m^2$. The objectives of this project were to revitalize the local economy of Sabuk, Gohan which is well Down for deserted coal mines, by creating a resort complex for family group users with an environmentally friendly ski facility. This design scheme addresses three areas of concerns: First, how to boost the local economy through the proposed ski resort. By limiting lodging facilities in the ski resort, we could induce more development in the nearby towns. In order to balance the economical benefit to towns of Sabuk and Gohan, we decided to have two separate ski base facilities in each town boundary. Second, how to encourage family-oriented use of the ski resort by designing user-friendly ski slope, especially for beginner skiers. We designed 50% more beginner-level ski slope compared to average ski resorts. Third, how to make environmentally-friendly ski resort by respecting the original land form. We minimized the damage to the natural environment by protecting valuable tree groves. Also, ski slopes are designed to reduce unnecessary earth movement. This was designed under the assumption that more valley-oriented slopes would result in less cutting and banking of earthwork； this assumption was verified in comparison with other ski resorts. It is expected that this desist would serve environmentally-friendly designs in ski slopes.

The study aims to examine consumer awareness of green fashion products and demographic characteristics by subdividing environmentally conscious consumers of such products in the current domestic fashion market. It then compares the result with the characteristics of environmentally conscious consumers studied by 1999 in order to understand the trend of the consumer group in the fashion market and to promote the use of green fashion products. Marketing strategies for green fashion products suggested by the study are as follows: First, fashion firms are required to develop and publicize shops selling recycled or second-hand clothing that environmentally conscious consumers show constant interest. For instance, clothing patterns may be developed to enable consumers to make their kids' clothing easily at home, and various garments made from recycled materials may stimulate environmentally conscious consumers' desire to buy. Particularly, advanced technologies should be developed and publicized to manufacture garments that can excel existing ones made of normal materials in their features in order to satisfy consumers' interest in clothing made from recycled PET bottles. In addition, various natural dyes should be developed to decrease water pollution. Second, it seems imperative to develop clothing made of recycled knitted apparel that attracts consumers' interest more than ever, fashionable multi-purpose clothing, and environmentally friendly materials. As the use of natural fur or leather can cause the endangerment of wild animals and the destruction of the ecosystem, synthetic fur or leather may be used to develop sophisticated products with the same texture as real ones to attract environmentally conscious consumers' interest.

In this paper, fractional factorial screening design (FFSD) and central composition design (CCD) were used to optimize the medium components for producing chitinase and gelatinase by Lysobacter capsici YS1215. Crab shell powder, nutrient broth and gelatin were proved to have significant effects on chitinase and gelatinase activity by FFSD first. An optimal medium was obtained by using a three factor CCD, which consisted of nutrient broth of $2.0gL^{-1}$, crab shell powder of $2.0gL^{-1}$ and gelatin of $1.0gL^{-1}$, respectively with the highest chitinase activity ($3.34UmL^{-1}$) and gelatinase activity ($14.15UmL^{-1}$). This value was 3.76 and 1.11 fold of the chitinase and gelatinase activity, respectively, compared to the lowest productive medium in the design matrix. In investigating potential of these enzymes partially purified from L. capsici YS1215 for biotechnological use, the crude enzymes was found to be inhibition against pathogenic fungal mycelia: Colletotrichum gleosporioides, Phytophthora capsici, and Rhizoctonia solani. In this study, we demonstrated the optimal medium for producing the chitinolytic and gelatinolytic enzymes by the strain YS1215 and the role of their enzymes that may be useful for further development of a biotechnological use and agricultural use for biological control of phytopathogenic fungi.

Even in case of new materials, materials that are not only harmless for the current global environment but also have high-performance and high-function are sought-after in consideration of the global environmental problems. Moreover, in construction areas where a large amount of cement and concrete are used, the establishment of the recycling technology or transformation into resources and energy materials are being put in place. And also, in a situation where the slow and relaxed city and rural life have a high priority, the need for cement and concrete as environmentally friendly new materials that best suit the emotions in human beings is on the rise and a new way to make good use of cement and concrete as new materials in construction technology should be sought. The recently introduced functional and environmentally friendly concrete is aimed at enhancing health through the adjustments of the body biorhythm using far-infrared. Minerals that contain a great amount of the elements with the frequent occurrence of the infrared among earth minerals and concrete are mixed to use structures or finishing materials, which will tackle the issues of smells, mold and corrosion.

Turfgrass, the most widely grown ornamental crop, is severely affected by fungal pathogens including Sclerotinia homoeocarpa, Rhizoctonia solani, and Magnaporthe poae. At present, turfgrass fungal disease management predominantly relies on synthetic fungicide treatments. However, the extensive application of fungicides to the soil increases residual detection frequency, raising concerns for the environment and human health. The bacterial volatile compound, 2,3-butanediol (BDO), was found to induce plant resistance. In this study, we evaluated the disease control efficacy of a combination of stereoisomers of 2,3-BDO and commercial fungicides against turfgrass fungal diseases in both growth room and fields. In the growth room experiment, the combination of 0.9% 2R,3R-BDO (levo) soluble liquid (SL) formulation and 9% 2R,3S-BDO (meso) SL with half concentration of fungicides significantly increased the disease control efficacy against dollar spot and summer patch disease when compared to the half concentration of fungicide alone. In field experiments, the disease control efficiency of levo 0.9% and meso 9% SL, in combination with a fungicide, was confirmed against dollar spot and large patch disease. Additionally, the induction of defense-related genes involved in the salicylic acid and jasmonic acid/ethylene signaling pathways and reactive oxygen species detoxification-related genes under Clarireedia sp. infection was confirmed with levo 0.9% and meso 9% SL treatment in creeping bentgrass. Our findings suggest that 2,3-BDO isomer formulations can be combined with chemical fungicides as a new integrated tool to control Clarireedia sp. infection in turfgrass, thereby reducing the use of chemical fungicides.
