Radioprotective effects of ginger essential oil (GEO) on mortality, body weight alteration, hematological parameters, antioxidant status and chromosomal damage were studied in irradiated mice. Regression analysis of survival data in mice exposed to radiation yielded LD50/30 as 7.12 and 10.14 Gy for control (irradiation alone) and experimental (GEO-treated irradiated) mice, respectively, with a dose reduction factor (DRF) of 1.42. In mice exposed to whole-body gamma-irradiation (6 Gy), GEO pre-treatment at 100 and 500 mg/kg b.wt (orally) significantly ameliorated decreased hematological and immunological parameters. Radiation induced reduction in intestinal tissue antioxidant enzyme levels such as superoxide dismutase, catalase, glutathione peroxidase and glutathione was also reversed following administration of GEO. Tissue architecture of small intestine which was damaged following irradiation was improved upon administration of GEO. Anticlastogenic effects of GEO were studied by micronuclei assay, chromosomal aberration and alkaline gel electrophoresis assay. GEO significantly decreased the formation of micronuclei, increased the P/N ratio, inhibited the formation of chromosomal aberrations and protected agaisnt cellular DNA damage in bone marrow cells as revealed by comet assay. These results are supportive of use of GEO as a potential radioprotective compound.

'Mu-acupuncture treatment(繆刺法)' and 'Geo-acupuncture treatment(巨刺法)' are the ways of taking acupuncture points on the sound side of a human body and not on the unsound side of a human body to treat disease, 'Mu-acupuncture treatment(繆刺法)' is applicable to 'Transverse meridian disease(絡脈病)', 'Geo-acupuncture treatment(巨刺法)' is applicable to 'Longitudinal meridian disease(經脈病)'. To diagnose a disease as transverse meridian disease or longitudinal meridian disease depends on 'Feeling pulse at the nine spots of three parts on a body for diagnosis (三部九候診)'. 'Mu-acupuncture treatment(繆刺法)' takes a 'Rak-acupuncture point(絡穴)' under a wrist and a ankle joint. The method of taking it, two ways, are 'Yu(痏)' and 'The treatment getting some blood(出血療法)'. 'Yu(?)' which is similar to 'Quick-getting acupuncture into and out (單刺法)' means the number of times doing acupuncture and is different from 'The treatment getting some blood (出血療法)' which is typically considered as 'Yu(?)'. Meanwhile, judging from the changes of the methods of feeling pulse for diagnosis and the symptoms of a certain disease, though it is a precondition that 'Biased-Gi(邪氣)' stays at 'The Large transverse meridian(大絡)' in 'The theory of Mu-acupuncture treatment(繆刺論)', it is hard to consider the symptoms of 'Transverse meridian disease(絡脈病)' described in 'The theory of Mu-acupuncture treatment(繆刺論)' as the pure symptoms of 'Transverse meridian disease(絡脈病)'.

1) The color of JOGORI and CHIMA was such gorgeous and those garments were put on during the events of GAM-EUNG-CHUNG-BAI HO-GU-GEO-RI JO-SANG-GEO-RI DEWT-JUN and CHAN-BOO-GEO-RI. 2)BULSA-JANG-SAM(JE-SUK-GEO-RI) was white colored and had wide sleeves putting on a pink priestrobe and a pink belt on it 3) they put on HONG-CHUL-NIK(GU-REUNG) and CHONG-CHUL-NIK(DAE-GEO-RI). 4)They put on GOO-GUN-BOK(JUN-RIP JUN-BOK(BYUL-SUNG-GEO-RI) DONG-DA-RI(Expel the demon) 5) MONG-DOO-RI(MAN-SIN-MAL-BYUNG) put on the garment constructed with the color and from of a white straight collar a wide sleeve and a pink belt 6) A long robe was colored with green (GAM-EUNG-CHUNG-BAI) and was used not as a headdress but as a man's overcoat. 7) CHANG-EUI was a green colored small CHAHG-EUI(SUNG-JO-GEO-RI). As observed above the Shaman apprel during Chosun Dynasty is a part of the traditional clothing originated from THE THEORY OF THE COSMIC DUAL FORCES and THEORY OF THE COSMIC DUAL FORCES and the FIVE ELEMENTS (i.e. metal wood water fire and earth) It's basic form and wearing method were not so different from the traditional clothing silmilar to the official uniform during Chosun Dynasty and the official uniform was the symbol of authority(almost almighty) at that time of period and to that the Shaman apparel was constructed with the more gorgeous colors to emphasize the sanctity or the descent of the Divine Being from heaven. We realized that a Shaman had put on the symbolic garment suitable for the grade and nature of the Divine Body at every events to enter into " The World of Gods"Gods."

In this study, deformation behavior of existing concrete face rockfill dam, which is raised to a certain height to enhance storage capacity or to improve hydraulic and hydrologic stability, is examined using numerical analysis method. The results obtained from FEM analysis show a possibility that additional fill at downstram slope of existing CFRD dam body may lead undesirable deformations and stresses in existing dam body, especially in face concrete, such as settlements in upper part and bulging in lower part, excessive bending moments, and eventualy tensile cracks. Therefore, in designing multi-staged raising construction of CFRD, it is essential to consider deformations and stresses to be developed within and between exisiting dam body and added parts due to additional fill, and to prepare a proper measure to prevent abnormal deformations and stresses in the dam body including added parts.

Using 2D numerical analysis that covers the largest section of the dam body, a process is generally performed when evaluating its stability against seepage. The quantity of seepage is first obtained by assuming that its bottom topography is in the simple form of a rectangle, it is then calculated by reflecting its sectional shape during this process of analyzing the seepage quantity. Considering that various forms of dams are being constructed on various types of ground, thanks to more recent technological advances, it is judged more appropriate to draw a conclusion by means of the results on reflecting the realistic shape and topographical conditions of the dam body through 3D numerical analysis. Therefore, this study intends to present a method designed to carry out safety management by evaluating the correct quantity of water leakage that passes only through the dam body, having excluded other factors that include the amount of rainfall through the 3D FEM analysis.

This paper presents procedure and prediction method of internal and external stabilities when designing D.C.M, with main factors to be considered, such as chemical reaction of additive, physical properties of stabilized body and mixing strength. Results show that through case studies, a design unconfined compressive strength of stabilized body (hereafter referred to as 'compressive strength') directly depends on the quantity of cement, which is decided by laboratory test, and the compressive strength enormously affects internal and external stabilities. So laboratory mixing test to obtain the compressive strength for design allowable stress should be given careful considerations.

This study was performed to investigate the effect of essential oils and ethanolic extracts of approximately 650 plant species on acetylcholine esterase (AChE) enzyme activity using Ellman's colorimetric method in 96-well microplates. The results showed that the ethanolic extracts from twig of Sophora subprostrata, twig of Phellodendron amurense, seed of Corylopsis coreana, and essential oil (EO) from Citrus paradisi, Cupressus sempervirens, Ocimum basilicum, Pinus sylvestris and Rosmarinus officinalis inhibited more than 80% of AChE activity. Among these, EO from Pinus sylvestris, C. sempervirens and C paradisi exhibited higher values of AChE inhibitory activity, which were 75, 84 and 99% at a concentration of 50 ug/ml, respectively. Finally, EO from C paradisi (grapefruit, GEO) showed the highest inhibitory activity towards AChE, which showed 91% of inhibition at a concentration of 20 ug/ml. We also examined the anti-dementia effects of GEO in mouse by passive avoidance test and Morris water maze test. The model mouse (male, ICR) of dementia (negative control) was induced by administration of scopolamine (1 mg/kg body weight). The latency time of sample group administrated with GEO (100 mg/kg, p.o.) increased significantly as compared with negative control on passive avoidance test. There were significant recovery from the scopolamine-induced deficits on learning and memory in water maze test through daily administrations with GEO (100 mg/kg, p.o.). From these results, we conclude that GEO treatment might enhance the cognitive function, suggesting that the EO of C. paradis may be a potential candidate for improvement of perceptive ability and dementia.

In recent geotechnical engineering, geothermal approach has been on the horizon to deal with geoenvironmental issues, freezing and thawing problems, and seepage phenomenon in dams and embankments. In this study, geothermal characteristic through inner body of dams and its influence on the seepage flow were experimented by lab test and field instrumentation. Also, one of up-to-date temperature monitoring technique, called as multi-channel thermal line sensing, was evaluated its availability. As a result of lab test, it is found that the seepage flow has influence on the geothermal characteristic and a potential of finding phreatic line and seepage fluctuation could be possible by continuous temperature monitoring using thermal line sensing skills. These kine of geothermal information could be available to the modelling of water geo-structure interaction. Out of short-term field tests, clear water table and temperature distribution of a dam were easily found through temperature monitoring in holes located near a reservoir and holes within a depth of constant temperature layer. However, it is also found that the geothermal flow and finding seepage line could not be easily understandable through multi-channel temperature monitoring because of the existence of constant temperature field, thermal conductivity of soils and rocks, and unsaturated characteristics of geo-material. In this case, long-term geothermal monitoring is recommended to find sudden fluctuation of seepage line and amount of leakage.
