Despite a current fascination with East Asian iconography such as Zen Style among contemporary designers, there is a lack of genuine cross-cultural discourse that could enable us to share essential design experiences. To bring the discussion a deeper level, traditional Japanese tea-house in its design philosophy of body-mind interplay is explored. Tea-house is a superb manifestation to reveal a holistic understanding of the world. Nondualistic realization is generally associated with the dominant tendency of traditional East Asian philosophy, namely the view that the self and environment, and that the mind and the body exist in unity. The essence of tea-house is not in its poetic style or meticulous details, but in its unmistakably monistic approach of creating inseparable form, function and meaning. Tea-house bestows dignity upon restraint, imperfection, discomfort, poverty, and even humility. This concept offers a tremendous insight since it implies that the rational and effective design solution to the greatest degree is not sufficient. Perhaps the most challenging question about tea-house is: How does our experience with human-made 'design' in the broadest sense help both our body and mind attain a full harmony of being? It is the heading which this research inquires.

This paper examines the current status of the Korean tea culture industry and explores ways to restore and develop Korean tea culture by referring to the responses of the neighboring countries of China. In order for the Korean tea industry and tea culture to expand, based on a strong tea industry, high-quality tea should be created to satisfy consumers' needs, health, convenience, and reasonable prices, and effective promotion and marketing should be carried out. In addition, it is necessary to reinterpret the traditional tea house and inherit the spirit of tea.

Plant biomass is a huge carbon-complex that has potential as a nutrient. Therefore we extracted and separated useful materials for plant growth from tea leaf and stem. The pre-treatment process including high temperature ($200^{\circ}C$) and pressure (20-40 kgf/$cm^2$) was treated for several minutes and extracted at $120^{\circ}C$ for 30-60 minutes. After that the chemical compositions and ingredients were analyzed from that plant-nutrient. As a result of mineral contents, calcium and magnesium concentrations are higher than other minerals. Also the result of carbohydrates analyses has shown that the sugar oligomer consists of xylose(95.3%) and glucose(4.7%), and the sugar monomer consists in the order of xylose (52.7%) > manose (22.8%) > arabinose (10.8%) > galactose (10.2%) > glucose (3.5%). Before applied to field, in vitro plant growth system and formulation were examined. To evaluate the effect of the nutrients, both strawberry green-house and persimmon fields were used in this test. The treated persimmons were heavier than controls scored at 13-22%. In addition, the storage-period was extended in the treated strawberries. Interestingly in the treated strawberry, the contents of polyphenols were increased (38-57%). These results suggest that the plant-nutrient can afford to help for plant growth and storage, and it can be substituted for other commercial nutrients. In conclusion, this plant-nutrient may help to extend eco-friendly or organic farming in Hadong-gun area.

Due to high oil prices and global warming problems, researching an alternative energy source and decreasing the energy usage will be the key in the future. Unlike other alternative energy sources, geothermal energy is less dependent on the surrounding environment. Geothermal energy is the ideal energy source for buildings due to the simple and space saving installation. The system is semi permanent once it is installed and this will help reduce the energy usage in controlling the climate in buildings. Geothermal energy does not emit carbon dioxide and other gases that are harmful to the environment. Therefore geothermal energy will be the key in solving high oil prices and a decrease in fossil fuels by applying the geothermal energy system to detached house to counter future energy crisis.

White grub damages various crops, trees and they can also be one of the most serious pests of turf grass in golf courses. This study was conducted to determine the biocontrol of white grubs with 18 different kinds (anise, camphor, castor, cinnamon, clove oil, citronella, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, rosemary, tea-tree, thyme, and turpentine) of plant essential oils in laboratory, green house and field. Anise oil (88.9%), linseed oil (100%), and tea-tree oil (88.9%) were highly effective among tested essential oils against 3rd instar of Bifurcanmala aulax in cap vial experiment. However, anise and linseed oils showed low mortality against $3^{rd}$ instar of Popillia japonica in pot greenhouse experiment. Efficacy of anise, linseed oil, and tea-tree was also different depending on target white grub in field trials. Correlated mortality showed 32.6% only in tea-tree oil treatment against pupae of Adoretus tenuimaculatus however, correlated mortality of anise, linseed and tea-tree oil were 54.8, 51.6 and 56.5% respectively against $3^{rd}$ instar of Exomala orientalis in the field trial in Adelscott Country Club in Hapcheon, Gyeongnam province.

A bacterial disease of tea plants(Camellia sinensis L.) was found in the graftage nursery grown under vinyl house conditions in Suncheon city, Korea, in spring of 2002. The primary symptoms of the disease include small, water-soaked and dark brown spot development on the young leaves. This spot gradually increases in size, especially taking on elongate shape along the midrib or vein of the leaf, and then turns black. The diseased leaves were defoliated easily. Ten strains were isolated from the infected leaf. Inoculation on tea leaf with these isolates produced the same symptoms of naturally infected plants. On the basis of stain reactions, morphological characterization, colony pattern, physiological and biochemical reactions, the bacterium was identified as Pseudomonas syringae pv. theae. This is the first report of brown blight of tea plant in Korea.

The 181,000 DWT Bulk Carrier has a different deck house type, which is not typical for previous bulk carriers, to meet the new international rules for bulk carriers. This new deck house has much smaller transverse breadth than the hull's transverse breath, resulting in large levels of the transverse response of the deck house. In addition, the longitudinal response of the funnel showed rather a large magnitude of vibration, which are excited by the ship's main excitations such as the main engine H-moment and the propeller surface forte when the ship operates at the NCR and the MCR speeds In the ballast condition. To solve these issues, the global forced vibration analysis has been performed for the ship and the ship structure has been modified to reduce the vibration level by increasing the girder depth and adjusting the engine room tank arrangement.

Traditional architecture has structural limits after some terms because it almost made by wood elements. So in the name of 'Restoration', by anatural process, repair works are accomplished. But the repair works of traditional buildings have some problems in spite of best men power and technology. To overcome this problems, we need more detailed studies for examine the reasons of destruction in elements of wooden buildings. The life limits of wooden buildings are caused by natural circumstances and humanic circumstances, the former has bad effect on the damage in wooden buildings. There are various elements of damage in the wooden buildings, earthquake, the falling of a thunderbolt, fire, and rain, microorganism, insect, and so on. Moreover pollutions-sulfurous acid gas, acidorganic matters -are important reason of shortening the life of wooden buildings. From 1981 till now we investigated important traditional buildings under repair works by the way scientific analysis to catch the sample - seramics, woods, insects, metals, etc. In this reports we suggest various method of investigation with two samples of tradional house made by wood, one is Kim Joo Tea House, the order is Simgum-dang of Magok-Sa(dwelling of monk).

This experiment was undertaken to screen the acaricidal effects of herb essential oils (pennyroyal, ylang ylang, citronella, lemon grass, tea tree, and rosemary) at different doses (0.1, 0.05, 0.025, 0.0125, and $0.00625{\mu}l/cm2$) and exposure times (5, 10, 20, 20, 30 and 60 min) on house dust mites Dermatophgoides farinae and D. pteronyssinus. The most effective acaricidal components of pennyroyal (Mentha pulegium) were analyzed using a gas chromatography-mass spectrometer (GC-MS). Of these essential oils, the most effective was pennyroyal, which is composed essentially of pulegone (> 99%), at a dose of $0.025{\mu}l/cm^2$, which at an exposure time of 5 min killed more than 98% of house dust mites. In the pennyroyal fumigation test, the closed method was more effective than the open method and maximum acaricidal effect was 100% at $0.025{\mu}l/cm^2$, 60 min. The results show that herb essential oils, in particular, pennyroyal was proved to have potent acaricidal activity.
