Aconitine has much Heat and Toxicity in its property, so many consideration is needed during its use. And there are many contraindications of its use. In the book of Dongyisusebowon, it has to be used when Soeumin has extreme Cold accompanied by Heat of deficiency type. In this case report, a 84 year-old male patient who had taken drugs containing Aconitine had severe Yin-Deficiency-Midday-Fever(陰虛午熱). And he had been treated with Sukjiwhanggosamtang(熟地黃苦參湯) and Dokwhaljiwhangtang(獨活地黃湯). Four conclusions can be made through this case. 1. Soyangin(少陽人) patients may have many side effects or adverse effects when they take drugs containing Aconitine even at a little volume. 2. Soyangin may have chest discomfort when they are constipated. This patient also complained chest discomfort after stroke and toxicosis of Aconitine. 3. Between Sukjiwhanggosamtang(熟地黃苦參湯) and Dokwhaljiwhangtang(獨活地黃湯), Sukjiwhanghosamtang is more effective for this patient who has been skin psoriasis and lower diabetes(下消) for a long time. 4. Although Sukjiwhanghosamtang does not include any antidote drug of Aconitine, it may be used only when defferenciation of symdrome is proper on Sasang Constituional Medicine.

Ramulus et Uncus Uncariae (JGD) has sweet in flavour and slightly cold in property, acting on the liver and pericardium channels. This drug was described in a medical classic as having the ability to remove 'heat', check hyperfunction of the liver and relieve dizziness, tremors, and convulsions, and subdue 'endogenous wind'. So this study was estimated to check the anti-neuropathological effect of JGD on the Alzheimer in βAPP overexpression in neuroblastoma cell line and JGD extract was showed significantly anti-alzheimer effects (50 and 100 μg/㎖ of JGD extracts) compared with control group. Ramulus et Uncus Uncariae has anti-alzheimer effects on the βAPP overexpression in neuroblastoma cell line. So we expect that Ramulus et Uncus Uncariae may be used as a drug for neurodegenerative disease, such as stroke, Alzheimer's disease (AD). These results indicate that Ramulus et Uncus Uncariae possess strong inhibitory effect in the nervous system of apoptosis and repair effect against the degeneration of Neuroblastoma cells by βAPP expression.

Thermal behavior on the cylinder block of a 4-cylinder, 4-stroke 2.0L SOHC gasoline engine was numerically and experimentally analyzed. The numerical calculation was performed using the finite element method. The cylinder block was modelled as a three dimensional finite element by considering its geometry. The physical domain was devided into hexahedron elements. 16 thermocouples were installed at points of 2mm inside from cylinder wall near top ring of piston in cylinder block, which points have suffered major thermal loads and suggested as proper measurement points for engine design by industrial engineers. Under full load and 9$0^{\circ}C$ coolant temperature condition, temperature behavior of cylinder block according to engine speed were analyzed. The results showed that temperature rose gradually to conform to a function of 2nd~4th order of engine speed at intake side, exhaust and siamese side, respectively. As engine load was changed from 100 to 50% by 25% step, temperature curve also conformed to 2nd~7th order function of engine speed. Temperature differences by load condition were similar among 100, 75% and 50%. Under full load and coolant temperature of 11$0^{\circ}C$, temperature behavior were also analyzed and the result also showed conformance to 2n d~7th order function of engine speed. Temperature curve was transferred in parallel upwards corresponding coolant temperature rise.

Pulse diagnosis is considered one of the most important diagnostic methods in traditional Korean medicine. Nonetheless, there have been troubles of using pulse diagnosis practically, for the lack of its differential standards and standardized terminology. Rapid pulse belongs to the several traditional pulse types. Rapid pulse was first mentioned in the chinese medical book Haungdineijin that matched it to the fever as well as yang in the human body. Meanwhile, chinese doctors in Ming Ching dynasty of China suggested that rapid pulse meant more of the yin, cold-related reaction than yang and fever. In this study, we organized the past arguments of the rapid pulse and went back tracking what biological activities could be possibly linked to the rapid pulse. Thus, we figured out that the inflammatory mechanism has a close connection with the rapid pulse. The definition of the rapid pulse in Haungdineijin was indicating the acute inflammatory response, while in Ming Ching dynasty, it indicated the chronic inflammation. This is the deficiency-excess pattern of the rapid pulse. Furthermore, we discussed the nonexpression pattern of the rapid pulse which could be happened in case of the heat stroke, etc.

The simulation program which predicts the gas behavior in a spark ignition engine has been developed and verified by the comparison with the experimental results foy the MPI engine, naturally aspirated and turbochared engines with a carburettor. First paper describes the calculations of the behavior of gas in the intake and exhaust system. The generalized method of characteristics including friction, heat transfer, area change and entropy gradients was used to analyse the pipe flow The constant-Pressure model was applied for the analysis of the flow through engine valved, and the constant-pressure perfect-mixing model was applied for the flow at manifold junction. The concept of the sudden area change was used for the muffler and catalytic convertor. Fer the plenum chamber in an MPI engine, constant-pressure model and constant-volume model were both examined. Through the comparison of predicted results with experiments, the simulation program was verified by showing good prediction of the behavior of IC engine qualitatively and quantitatively under wide range of operating conditions.

Dual fuel combustion strategy with di-methl ether (DME) and gasoline was tested in a compression ignition engine. Characteristics of combustion and emissions were analyzed with the variation of engine operating parameters such as fuel proportion, DME injection timing, intake oxygen concentration, DME injection pressure and so forth. Gasoline was injected into the intake manifold to form the homogeneous mixture with intake charge and DME was injected directly into the cylinder at the late compression stroke to ignite the homogeneous gasoline-air mixture. Dual fuel combustion strategy was advantageous in achievement of higher thermal efficiency and low NOx emission compared with DME single fuel combustion. Higher thermal efficiency was attributed to the lower heat tranfer loss from the decreased combustion temperature since the amount of lean premixed combustion was increased with the larger amount of gasoline proportion. Lower NOx emissions were also possible by lowering the combustion temperature.

In the direct injected gasoline engine, atomized spray is desired to achieve efficient mixture formation needed to good engine performance because the injection process leaves little time for the evaporation of fuels. Therefore, substantial understanding of global spray structure and quantitative characteristics of spray are decisive technology to optimize combustion system of a GDI engine. The combustion and emission characteristics of gasoline-fueled stratified-charge compression ignition(SCCI) engine according to intake temperature and compression ratio was examined. The fuel was injected directly to the cylinder under the high temperature condition resulting from heating the intake port. With this injection strategy, the SCCI combustion region was expanded dramatically without any increase in NOx emissions, which were seen in the case of compression stroke injection. Injection timing during the intake temperature was found to be an important parameter that affects the SCCI region width. The mixture stratification and the fuel reformation can be utilized to reduce the required intake temperature for suitable SCCI combustion under each set of engine speed and compression ratio conditions.
