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.

굼벵이는 각종 작물과 나무에 피해를 줄 뿐만 아니라 특히 골프장 잔디에 피해를 주는 주요해충의 하나이다. 본 연구는 18종의 식물정유(anise oil, camphor, castor, cinnamon, clove oil, citronella, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, rosemary, tea-tree, thyme, turpentine)를 이용하여 굼벵이의 환경친화적 방제 가능성을 알아보고자 실내와 온실, 야외에서 실험을 수행하였다. Cap vial실험에서 홈줄풍뎅이 3령충에 효과가 높은 정유는 anise (88.9%)와 linseed oil (100%) 및 tea-tree oil (88.9%)이었다. 온실 pot에서 왜콩풍뎅이 3령충에 대한 anise와 linseed oil의 효과는 낮게 나타났다. 야외에서 anise와 linseed 및 tea-tree oil의 효과도 대상 굼벵이의 종류에 따라 차이를 보였다. 주둥무늬차색풍뎅이 번데기에 대해서는 tea-tree oil 처리에서만 32.6%의 보정사충율을 보였으나 등얼룩풍뎅이 3령충에 대해서는 anise와 linseed, tea-tree oil이 각각 54.8%, 51.6%, 56.5%의 보정사충율을 보였다.

2002년 봄, 순천시 비닐 하우스에서 육묘중인 차나무에 세균병이 발견되었다. 초기 병반은 신엽에 작은 수침상 병반이 나타났으며 갈색반점으로 변하였다. 이 병반은 점점 커졌으며, 중륵 또는 엽맥을 따라 신장하였으며 검은색으로 변하였고, 병든 잎은 쉽게 낙엽이 되었다. 병반으로부터 10균주를 분리하여 잎에 접종한 결과 자연 병반과 동일한 병징이 나타났다. 병원세균은 염색반응, 형태적 특성, colony 패턴, 생리적, 생화학적 반응에 따라 Pseudomonas syringae pv. theae로 동정되었다. 국내에서 이 균에 의한 차나무 세균병은 아직 보고되지 않았으므로 병명을 차나무 갈색마름병(brown blight)으로 명명할 것을 제안한다.

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.
