Hemorrhage is a devastating type of stroke, accounts for 15-20% of all strokes. This disease can cause cognitive dysfunction with a very high mortality rate. Cupping therapy of Traditional Korean medicine has frequently been used to relieve a variety of diseases or clinical conditions, although not in the memory loss after hemorrhage. This study was designed to evaluate the effects of cupping therapy on learning and memory with Y-maze test, as well as its effects on different molecular changes in hippocampus following the induction of hemorrhage in rats. Cupping, using vacuum cupping machine, was applied at target area for 5 min daily for 7 consecutive days, commencing 1 day after brain impairment. As a result, induction of hemorrhage enhanced memory deficit, suppressed brain-derived neurotrophin factor (BDNF) in the hippocampus. Cupping treatment effectively reversed collagenase-induced cognitive impairment in SD rats which was represented by improvement of spontaneous alterations in Y-maze test. In addition, BDNF expression was enhanced after cupping therapy. The present results suggest that the therapeutic effects of cupping treatment after hemorrhage is involved in expression of BDNF.

The objective of this study was to find the effect of the mixture of the nonionic surfactant and bioactive agent that solubilizes trichlorobenzene (TCB) present as a contaminant for surfactant-enhanced soil flushing (SESF). Three different nonionic surfactants and two different bioactive agents were obtained from four companies. Separate funnel experiments and shaker table agitation / centrifugation experiments were used for the test. Based on the separate funnel experimental results, three suitable mixture agents (APG + OSE, Brij 35 + MOSE, T-Maz 60 + MOSE) were selected. In the shaker table agitation / centrifugation experiments, these three different mixture agents were reduced to one (T-Maz 60 +MOSE). The maximum removal (95%) of TCB was obtained using a mixture of the nonionic surfactant and bioactive agent. Therefore, the used test methods and results can be used for SESF.

Carcinogenicity of di(2-ethylhexyl)phthalate(DEHP) to the mose forestomach and its inhibitor activity for the initiation of Benzo[a]pyrene(BP)-induced mouse forestomach neoplasia were studied on the mouse forestomach carcinogenesis regimen. One hundred female ICR mice(6~7 weeks of age) were hosed in a poly-carbonate cage (4 mice/cage) in a humidity- and temperature-controlled room subjected to a semipurified diet for a week. Mice were divided into 4 treatment groups (25 mice/treatment): Basal diet, DEHP, BP, and BP+DEHP. On Monday and wednesday, 0.1ML DEHP mixed with 0.1ml olive oil (for DEHP and DEHP+BP treatment groups) or 0.1ml saline+0.1ml olive oil (for basal diet group) was intubated, p.o., and on Friday, 2mg BP dissolved in 0.2ml olive oil (for BP and BP+DEHP treatment groups) was intubated, p.o. This cycle was repeated for 4 weeks. Beginning with the first intubation of BP an continuing thereafter, body weight and food intake were recorded once and twice weekly, respectively. All surviving mice were sacrificed 22 weeks after the first dose of BP intubation and countered forestomach tumor. No tumor was formed by DEHP treatment. 5.75 tumors per mouse was formed by BP treatment, whereas its number was reduced to 4.53 by BP+DEHP treatment. Similar results were seen in the tumor incidence. Body weight gain was not affected by DEHP treatment, when compared to that b basal diet treatment. The body weight was significantly reduced by BP treatment, but its reduction was recovered to the level of the basal diet group by BP+DEHP treatment. No significant difference was seen in food intake among all treatment groups. These results indicate that DEHP lacks carcinogenic activity to the mose forestomach and rather inhibits the initiation of BP-induced mose forestomach neoplasia.

This study has researched the management status and the pollution level of water, soil, stream sediments of 11 abandoned coal mines out of a total of 12 within Obong-Dam area except Bukyung mine, which was submerged when constructing Obong-Dam, and selected areas which are in needs to have pollution control facilities in the first place. From the results of examination on the runoff at the waste rock pile and mineheads, the runoff from Sueun mine (pH, Fe, Al), Samwon mine (pH, Al), Wangdo mine (pH, Al), Mose mine (pH, Fe, Al) and Daeryeong mine (pH) exceeded the permissible discharge standards of the water quality, but the water at merging point with Obong-Dam after joined with Doma branch satisfied both Water Quality Standards and Drinking Water Quality Standards. In regard to groundwater contamination, it is found that areas where exceeded the Drinking Water Quality Standards are Wangdo mine (pH), Jangjae mine (pH, Zn), Daeryeong mine (pH) whereas all areas satisfied Soil Contamination Warning Standards of Soil Environmental Conservation Law. When comparing a research result on underwater sediments of branches of abandoned mines to the EPA Guidelines for classification of great lakes harbor sediments, Dongguk Gaerim (Fe), Jungwon mine (Fe), Daebo mine (Mn), Samwon mine (Mn) and Daeryeong mine (Mn) showed mid-level of contamination, whereas Sueun (Fe, Mn), Daebo mine (Fe), Woosung mine (Fe, Mn), Wangdo mine (Fe, Mn), Mose mine (Fe) and Daeryeong mine (Fe) showed high-level of contamination. In addition, contamination levels of underwater sediments in Wangsan and Doma branch where abandoned mine's branches merge together, Wangsan branch showed no contamination at all whereas Doma branch shows mid-level of contamination which reflect the Doma branch is affected by waste rock pile and minehead runoff of the abandoned mines in the Doma branch area. It is concluded that Mose mine and Sueun mine required treatment of acid mine drainage. and Wangdo, Jungwon, and Samwon mines were in need of mine tailing and erosion control work. The Samwon mine additionally required a control system for closed minehead runoff. Although the Samwon mine reached a high concentration of Al, Mn $Ca^{2+}$, $SO{_4}^{2-}$ in the runoff, the levels decreased after it was combined with a tributary. It has been concluded that after further monitoring of the cause of pollution, a preventive measure system may be needed to be built.

The transfer function was introduced to establish the prediction method for the DO concentration at the intaking point of Kongju Water Works System. In the mose cases we analyze a single time series without explicitly using information contained in the related time series. In many forecasting situations, other events will systematically influence the series to be forecasted(the dependent variables), and therefore, there is need to go beyond a univariate forecasting model. Thus, we must bulid a forecasting model that incorporates more than one time series and introduces explicitly the dynamic characteristics of the system. Such a model is called a multiple time series model or transfer function model. The purpose of this study is to develop the stochastic stream water quality model for the intaking station of Kongju city waterworks in Keum river system. The performance of the multiplicative ARIMA model and the transfer function noise model were examined through comparisons between the historical and generated monthly dissolved oxygen series. The result reveal that the transfer function noise model lead to the improved accuracy.

In this study, the inclined endmilling process with a 3-axis machining center using inalined jigs is introduced for the purpose of reducing overall Dies/Molds machining time and improving the machining accuracies. In order to analyse the cutting mechanism of a given endmill more accurateky, the unification of the cutting mechanism model of 3-different-kind endmills is examined by using the mose radius as a parameter. By adding radial runouts as a parameter which influences on surface roughness, the superposition method which defines the effective cusp heigh superposing the cutter mark height and the conventional cusp height is modified. And 3-D surface topography predicted in this paper looks like the surface normally observed in practice. Through machining experiments, the adequacy of the superposition algorithm was confirmed.
