From the Study on the Pricking blood therapy of ${\ulcorner}$HwangjeNaegyeong${\lrcorner}$, we conclude as follows; 1. The blood is apt to coagulate because of having concreteness. The blood is mainly coagulate as the collateral Meridian, minute collaterals, superficial collaterals and superficial vessels. By way of the Pricking blood therapy, the Stagnation of blood can be circulated, pathogenic factor removed, Eum-Yang(陰陽) and Gi and blood(氣血) can reach their balance. 2. To bloodletting, we should examine minutely, touch carefully with the region of the stagnated blood. After close observation of the stagnated blood, we should remove the stagnated blood up to clear. At the same time, we should observe carefully the color of the stagnated blood. 3. The acupuncture used for the Pricking blood therapy were stone needle, Bongchim(鋒鍼), Chamchim(?鍼), Pichim(?鍼) and Hochim(毫鍼) etc: After ages, from the base of Bongchim(鋒鍼), the three-edged needle became typical form. The skill of the Pricking blood therapy also became diverse, clinical application became wide. 4. After giving medical treatment with the Pricking blood therapy, reactions are various. Among them are side effects and normal effects. 5. The Pricking blood therapy is usually considered as simple sectional curing method, while it was considered as curing disease of JangBu(臟腑) or meridians in ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$. Therefore, if we sould apply the Pricking blood therapy on the basis of ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$, we should carefully understand the pattern identification according to Meridians and collaterals, and pattern identification of the Jang-Bu organs.

Coronary artery disease (CAD) such as angina pectoris and myocardial infarction(MI) have been considered the major cause of death for decaddes . THeir incidence and prevalence are still increasing . Numerous studies have been done on the risk factor analysis of CAD in Western countries. Since the diet in Western countries is different from that in Korea it is difficult to assume that the Korean diet has the same effects as its western counterpeart on the development of CAD . THus the gudidelines for the Western CAD patients can no totally be applied to Koreans. This study was conducted to investigate the relationship between diet and CAD in Koreans. Subjects were comprised of patients admitted to the hospital for chest pain with poxxilbe CAD (men 129, women 65) . They were divided into the following three groups according to angiographic results ; angiogrphically normal coronary artery group (control), single vessel disease group(SVD) and multiple vessel disease group (MVD) . Intakes of dietary fatty acids and other nutrients were assessed by the semiquantitative food frequency method. Blood was also obtained from subjects for serum lipid analysis. Serum lipid profiles of men were clearly different form those of women. For men, serum choesterol levels (or LDL or LDL/HDL) seemed to be higher in the MVD group compared to the control and SVD groups, while TG level was significantly higher in the MVD group for women. Both men and women showed significantly higher caloric , fiber and vitamins C and A intakes in the MVD group than in the other two groups. Higher caloric intakes was due to higher intakes of carbohydrate and protein rather than fat intake. In terms of fatty acids intake, there were no significant differences among the three groups . Smoking seemed to have great effect on eating patterns in CAD patients. Smokers and ex-smokers showed significantly higher intakes of most nutrients including individual fatty acids that non-smokers. The results of stepwise regression showed that moderate alcohol intake decreases LDL levels and increases HDL levels and smoking seems to lowe HDL levels in CAD patients.

Association of antigenic peptide with class I MHC is believed to be crucial for maintaining stable conformation of class I molecules. T2 cells that are defective in TAP gene function mainly express class I molecules with an unstable conformation due to little or no association with antigenic peptides, whereas T1 cells that are normal in TAP gene function mainly express the stable form of class I molecules. In this work, attempts were made to determine the molecular stability of stable and unstable class I molecules. Dissociation of HLA-A2 molecules on T1 and T2 cells was monitored by flow cytometry using anti-HLA-A2 antibody after the cells were treated with brefeldin A to shut down the transport of newly-assembled HLA-A2. Estimated dissociation rate constants for the stable and unstable forms of HLA-A2 were 0.076 $h^{-1}$ and 0.66 $h^{-1}$, respectively. It appeared that both T1 and T2 cells express stable and unstable class I complex, but with different ratios of the two forms. Furthermore, $interferon-{\gamma}$ treatment of T1 cells appeared to induce the expression of both the stable and unstable class I molecules. These results demonstrate that class I MHC molecules can be divided into two groups in terms of structural stability and that they exist on the cell surface in both forms in a certain ratio.

Iodine exists as a trace element in seawater, with total iodine being generally constant at about 0.45-0.55 μM. Almost all of this iodine occurs in two main forms: iodate and iodide. Iodate is the thermodynamically stable form under normal seawater conditions, and thus should be the only iodine-containing species in the water column. However, iodate concentrations are found to vary considerably, being generally greater at depth and lower at the surface, while iodide concentrations follow the reverse pattern, being anomalously accumulated in the euphotic zone and decreasing with depth. The fact that iodide concentrations follow a depth dependence corresponding to the euphotic zone suggests that biological activity is the source of the reduced iodine. Nonetheless, the nature and source of iodate reduction activity remains controversial. Here, using a combination of field and laboratory studies, we examine some of the questions raised in our and other previous studies, and seek further correlations between changes in iodine speciation and the presence of marine macro- and microalgae. The present results indicate that microalgal growth per se does not seem to be responsible for the reduction of iodate to iodide. However, there is some support for the hypothesis that iodate reduction can occur due to release of cellular reducing agents that accompany cell senescence during phytoplankton bloom declines. In addition, support is given to the concept that macroalgal species such as giant kelp (Macrocystis pyrifera) can take up both iodide and iodate from seawater (albeit on a slower time scale). We propose a mechanism whereby iodate is reduced to iodide at the cell surface by cell surface reductases and is taken up directly as such without reentering the bulk solution.

This study developed a flood index which evaluates runoff characteristics. Runoff characteristics expressed in a hydrograph were reflected in the flood index in the form of characteristic factors such as a rising curve gradient, a peak discharge, a flood response time, and a flood discharge volume prior to peak. This study applied the standardization method to estimate the relative severity of the characteristic factors by transforming the distribution of characteristic factors into the standard normal distribution. The flood index developed in this study is a comprehensive flood index (CFI) which makes up for the weak points of a flash flood index (FFI) in determining relative severities. The CFI was applied to Han River basin and Selma River basin, and was compared with the FFI based on the correlation analysis and the regression analysis. The CFI could comprehensively evaluate flood runoff characteristics because the CFI is not dominated by a specific characteristic factor, and the CFI could explain more efficiently the relationship between rainfall and runoff than the FFI.

Ti-6Al-4V alloys are widely used as metal-lic biomaterials in dentistry and orthopedics due to its excellent biocompatibility and me-chanical properties. However, because of low biological activity, it is difficult to form bone growth directly on the surface of titanium implants. For this reason, surface treatment of plasma electrolytic oxidation(PEO) was used for dental implants. To enhance bioac-tivity on the surface, strontium(Sr) and sili-con(Si) ions can be added to PEO treated sur-face in the electrolyte containing these ions. The presence of Sr in the coating enhances osteoblast activity and differentiation, where-as it inhibits osteoclast production and prolif-eration. And Si has been found to be essen-tial for normal bone, cartilage growth, and development. In this study, electrochemical characteristics of Ca, P, Sr, and Si ions from PEO-treated Ti-6Al-4V alloy surface was re-searched using various experimental instruments. DC power is used and Ti-6Al-4V al-loy was subjected to a voltage of 280 V for 3 minutes in the electrolyte containing 5, 10, 20M% Sr ion and 5M% Si ion. The morphol-ogies of PEO-treated Ti-6Al-4V alloy by electrochemical anodization were examined by field-emission scanning electron micro-scopes (FE-SEM), energy dispersive x-ray spectroscopy (EDS), x-ray diffraction (XRD) and corrosion analysis using AC impedance and potentiodynamic polarization test in 0.9% NaCl solution at similar body tempera-ture using a potentiostat with a scan rate of 1.67mV/s and potential range from -1500mV to + 2000mV.

This paper proposes real-time video transmission system by the car-mounted cameras based on MOST Network. Existing vehicles transmit videos by connecting the car-mounted cameras in the form of analog. However, the increase in the number of car-mounted cameras leads to development of the network to connect the cameras. In this paper, DSP is applied to process MPEG 2 encoding/decoding for real-time video transmission in a short period of time. MediaLB is employed to transfer data stream between DSP and MOST network controller. During this procedure, DSP cannot transport data stream directly from MediaLB. Therefore, FPGA is used to deliver data stream transmitting MediaLB to DSP. MediaLB is designed to streamline hardware/software application development for MOST Network and to support all MOST Network data transportation methods. As seen in this paper, the test results verify that real-time video transmission using proposed system operates in a normal matter.

Methanol extracts form four kinds of kimchi, which were differently prepared in kinds and levels of sub-ingredients, were given to Balb/c mice for 3 weeks (0.5 mg/kg/day). Peritoneal macrophages isolated from mice treated with kimchi extracts and saline were stimulated by lipopolysaccharide (LPS). K3 and K4 kimchis, containing more red pepper powder, garlic, Chinese pepper powder, mustard leaf and organically cultivated Korean cabbage, significantly increased NO production by the activated macrophages (p<0.05). K1, K2, K3 and K4 kimchi extracts (0.01, 0.1, 1.0 $\mu\textrm{g}$) significantly reduced the increased TGF-$\beta$1 production of H.pylori lysate (0.01 $\mu\textrm{g}$)-activated human epithelial RPMI 2650 cells (5$\times$10$^{4}$ cells/mL) at 24 and 48 hrs of treatment (p<0.01). However, the decreased TGF-$\beta$1 $\alpha$ production of RPMI 2650 cells by H. pylori lysate increased by treatment with kimchi extract for 72 hrs. Especially, K4 kimchi (containing organically cultivated Korean cabbage and more ingredients, modulated TGF-$\beta$1 production of H. pylori lysate-activated RPMI 2650 cells to the normal level (control) by treatment for 48 hrs. The treatment of K1 and K4 kimchi enhanced the LPS (0.01 $\mu\textrm{g}$/mL)-induced IL-6 production of splenocytes. The results suggest that kimchi might have an beneficial effect on cancer prevention due in part to the function enhancing NO production of activated macrophages. Our data suggest that kimchi could modulate TGF-$\beta$1 production by cancer cells and IL-6 production of splenocytes, thereby possibly contributing to control carcinogenesis and the immune system.
