Different types of bap(cooked rice) was cooked using barley or/and SoRiTae with rice as the base. Total(TS), rapidly digestible(RDS), slowly digestible(SDS) and resistant(RS) starch fractions were determined. Other physicochemical properties such as moisture, protein, amylose contents, protein digestion in vitro and color values as well as sensory properties of different bap were also investigated. Cooked rice with SoRiTae(RiSo) showed the highest moisture content of 63.9%, whereas other bap showed simillar content ranging from 62.3-63.0%. Crude protein content of RiSo was the highest, while that of cooked rice(Ri) was the lowest(p<0.05). Amylose content of RiBa was the highest, while that of RiSo was the lowest(p<0.05). In in vitro protein digestibility(IVPD), cooked rice with barley and SoRiTae(RiBaSo) was the highest, while Ri was the lowest, showing no significant difference at p<0.05. In starch fractions, as barley or/and SoRiTae were added to rice, a decrease in RDS content and increases in SDS and RS contents were observed. In addition, starch digestion index(SDI), which derived as an indicator of their in vitro starch digestibility and rapidly available glucose(RAG) value, which determined as a predictor of potential glycemic response decreased. A decrease in L value from RiSo and RiBaSo, which comprised of SoRiTae and increases in a and b values in RiSo and RiBa were observed, respectively. All sensory parameters involving color, glossiness, sweet taste, wetness, roughness, hardness and stickiness were shown to be a significant difference except sweet taste among different bap(p<0.05). L value of instrumental characteristic was negatively correlated with color of sensory characteristic and a value was positively correlated. Significant negative correlation was found between RS content and glossiness, however, positive correlation with roughness and hardness, respectively. These results suggested that cooked rice mixed with barley and SoRiTae contain significant RS and SDS contents and may improve diabetes and hyperlipidemia, due to the lowering RDS and RAG, respectively.

Purpose : This study was aimed to evaluate the changes of immunologic parameters during hospitalization, and the relationship between IgG and other laboratory or clinical indices in patients with acute poststreptococcal glomerulonephritis (APSGN). Methods : We reviewed the medical charts of 36 children with APSGN who showed ASO titer>250 Todd U/L and C3<70 mg/dL. We evaluated the levels of IgG and other laboratory parameters including C3 and ASO at admission and at discharge (14 cases). Results : The mean age of APSGN patients was $7.5{\pm}2.6$ year of age, and male-to-female ratio was 2.3:1. At presentation, hypertension (systolic blood pressure>125 mmHg), gross hematuria, and weight gain were observed in 27.8% (10/36), 80.1% (29/36), and 80% (24/30) of the patients, respectively. The mean IgG level was $1,432{\pm}322$ mg/dL ($1,025{\pm}234$ mg/dL in control group, P<0.001), and C3 and ASO levels were $26.1{\pm}16.1$ mg/dL and $1,068{\pm}730$ Todd U, respectively. There were no correlation between IgG level and the levels of any of the parameters analyzed (ASO, C3, BUN, creatinine and white blood cell count), and the severity of the disease assessed by the weight-change during admission. The patients aged<6 years of age (10 cases) had less degree of the weight-change, compared to those of the patients aged>8 years of age (15 cases) (-0.6% vs. -5.7%, P=0.01). The IgG and ASO levels did not change, but C3 (P=0.001) and IgM (P=0.02) levels increased during admission. Conclusion : Increased IgG and ASO levels in APSGN did not change, but C3 level increased during admission. IgG level was not correlated with other laboratory parameters (ASO and C3) and the severity of the disease. Younger children seem to have less severe clinical course compare to older children. With our hypothetic pathogenesis of APSGN, further studies are needed to resolve the pathogenesis of the disease including the increase of IgG.

As for the increasing demanding on the development of direct-ecological landfill monitoring methods, it is needed for critically defining the condition of landfills and their influence on the environment, quantifying the amount of enzymes and bacteria mainly concerned with biochemical reaction in the landfills. This study was thus conducted to understand the fates of contaminants in association with groundwater quality parameters. For the study, groundwater was seasonally sampled from four closed unsanitary landfills(i.e. Cheonan(C), Wonju(W), Nonsan(N), Pyeongtaek(P) sites) in which microbial diversity was simultaneously obtained by 16S rDNA methods. Subsequently, a number of primer sets were prepared for quantifying the specific gene of representative bacteria and the gene of encoding enzymes dominantly found in the landfills. The relationship between water quality parameters and gene quantification were compared based on correlation factors. Correlation between DSR(Sulfate reduction bacteria) gene and BOD(Biochemical Oxygen Demand) was greater than 0.8 while NSR(Nitrification bacteria-Nitrospira sp.) gene and nitrate were related more than 0.9. A stabilization indicator(BOD/COD) and MTOT(Methane Oxidation bacteria), MCR(Methyl coenzyme M reductase), Dde(Dechloromonas denitrificans) genes were correlated over 0.8, but ferric iron and Fli(Ferribacterium limineticm) gene were at the lowest of 0.7. For MTOT, it was at the highest related at 100% over BOD/COD. In addition, anaerobic genes(i.e., nirS-Nitrite reductase, MCR. Dde, DSR) and DO were also related more than 0.8, which showing anaerobic reactions generally dependant upon DO. As demonstrated in the study, molecular biological investigation and water quality parameters are highly co-linked, so that quantitative real-time PCR could be cooperatively used for assessing landfill stabilization in association with the conventional monitoring parameters.

Cancer development and the efficiency of chemotherapy relies on the patients calcium-related pathological status such as hyper- or hypocalcemica. In the present study, we investigated the effect of extracellular cations such as calcium and magnesium on the therapeutic efficacy of antitumor drugs. The analytic parameters used were cellular drug uptake/excretion and the chemosensitivity of the human breast cancer cell lines, MCF7 and MCF7/ADR. Both calcium and magnesium ions decreased the membrane permeability of cancer cells, which was determined bycell size analysis. These divalent ions also lowered the drug uptake and the cytoplasmic levels of rhodamine 123 and adriamycin, suggesting that they might interfere with the diffusion of these drugs by modifying the physical properties of the cytoplasmic membrane. The acute cytotoxicity of adriamycin after a short period of incubation correlated with changes in its cytoplasmic level. Our results indicate that these extracellular cations might play an important role in the therapeutic activities of anticancer drugs in cancer patients. These results also provide insight a new aspect of chemotherapy, because they suggest that the therapeutic dose of anti-cancer drugs should be modified in cancer-bearing patients presenting with abnormal blood calcium levels.
The aim of this study was to measure effects of the following items to pain and pain behavior reaction in patients with chronic orofacial pain. Items that contribute to the first factor(Environmental Influences) measure environmental sources of information that may affect illness behavior; Second factro(Loss of Control) measure appraisals and attributions perceived to influence personal views aobut pain; Third factor(Health Care Avoidance) measures a variety of avoidant behaviors; Fouth factor(Past and Current Experiences) measures experiences with treatment); Fifth factor(Physiological Responsivity) measures physiological parameters that are experienced in association with pain; Sixth factor(Thoughts of Disease Progression) measures thoughts regarding the etiology and progression of disease in relation to pain. 150 patients that were consist of 40 male and 110 female were participated in this study. The obtained results of this study were as follows : 1. Environmental influences and loss of control scales were recorded high score in patients with chronic orofacial pain 2. "Physician's descriptions of what your pain will be like" and "Physician's facial expression when they ask about your pain" items from the environmental influences were recorded high score. These results indicated that responsibility of doctro is very important to the pain reaction behavior of patients. Also, items from thoughts regarding the etiology and progression of disease in relation to pain influenced to the pain reaction. 3. There were significant defferences on the "nurses' descriptions of what you pain will be like", "physician's and nurses' facial expression when they ask about your pain", "TV and radio", and "Literature" items from the environmental influences between male and female patients. 4. There were no significant differences on the each scale between arthrogenous and combitnation group and significant correlated with all 6 scales.
This study aims to clarify the characteristics of the physical and mechanical properties of soil-slope failure of Okcheon metamorphic zone. Soil samples were collected from 35 collapsed and uncollapsed artificial slopes along national roads. A series of laboratory experiments was carried out to examine physical and mechanical properties of soils and rocks. The results show that failure slopes have weakness of failure at 0.75 of AMI or higher, 32% of liquid limit or higher, and 31% of saturated moisture content or higher. The plastic index of failure slopes is correlated to wet density and saturated density. It turned out that failure could easily happen according to a high plastic index even if the void ratio was low. The greater the contents of bigger-sized soil, i.e. contents of sands and gravels rather than of clays, is the greater the chance to fail at the slope.
Objectives The purpose of this study is to examine the relationship between skeletal maturity and heart rate variability (HRV) based on the bone age and HRV parameters. Methods 103 children from 6 years to 17 years of age, who do not have any disease-related symptom, and visited ${\bigcirc}{\bigcirc}$ oriental medicine hospital, are measured based on their bone age and short-term spectral analysis of HRV. Results 1. Skeletal maturity was significantly correlated with HRV indices: mean HRT and SDNN. As the skeletal maturity increases, the mean HRT was decreased and the SDNN was increased. 2. When classifying according to the skeletal maturity score, the mean HRT was higher in the 'below -0.4' group compare to '-0.3~0.7' group and '0.8~1.9' group. SDNN was higher in the '0.8~1.9' group compare to '-0.3~0.7' group, 'below -0.4' group 3. When classifying according to the sex, age and secondary sexual characteristics, as the skeletal maturity was increased, the mean HRT was significantly decreased and the SDNN was significantly increased only in the boys who did not develop secondary sexual characteristics. Conclusions Skeletal maturity could be statistically significant with HRV indices, especially to the boys and the children than the girls and the teenagers.
An ultra-wideband signal is characterized by a radiated spectrum with wide bandwidth around a relatively low center frequency. In this paper, the bit error rate (BER), packet error rate (PER), and data throughput performance for an ultra-wideband system with M-ary correlation receiver are analyze in additive white Gaussian noise (AWGN) and co-channel interference channel. To evaluate the performance of UWB system, a set of UWB communication waveform as pulse position modulated (PPM) signals consisting of more than one UWB pulse is used. The M-ary PPM signals are defined to be equally correlated in order to simplify the system performance analysis. The analysis for system performance shows that the wireless channel error significantly degrades throughput performance and can be effectively increased by hybrid ARQ scheme. Also, an attempt for comparing the data throughput of ultra-wideband system on different performance improvement schemes and parameters has been made. From the performance evaluation process, it is shown that the effects of wireless channel and hybrid ARQ scheme for ultra wideband M-ary PPM system can be evaluated by means of a suitable combination of the PER, throughput vs. signal-to-noise power ratio per bit.

The objective of this study was to compare the goodness of fit of four lactation curve models: Wood's Gamma model (WD), Wilmink (WL), and Pollott's multiplicative two (POL2) and three parameters (POL3) and to determine the environmental factors affecting the complete lactation curve of F1 dairy sheep under organic management. A total of 5,382 weekly milk yields records from 150 ewes, under organic management were used. Residual mean square (RMS), determination coefficients ($R^2$), and correlation (r) analysis were used as an indicator of goodness of fit for each model. WL model best fitted the lactation curves as indicated by the lower RMS values (0.019), followed by WD (0.023), POL2 (0.025) and POL3 (0.029). The four models provided total milk yield (TMY) estimations that were highly correlated (0.93 to 0.97) with observed TMY (89.9 kg). The four models under estimated peak yield (PY), whereas POL2 and POL3 gave nearer peak time lactation estimations. Ewes lambing in autumn had higher TMY and showed a typical curve shape. Higher TMY were recorded in second and third lambing. Season of lambing, number of lambing and type of lambing had a great influenced over TMY shaping the complete lactation curve of F1 dairy sheep. In general terms WL model showed the best fit to the F1 dairy sheep lactation curve under organic management.

The structural deterioration of concrete structures due to reinforcement corrosion is a major worldwide problem. Service life of the age-degraded concrete structures is governed by the protective action provided by the cover concrete against the susceptibility of the reinforcement to the corrosive environment. The corrosion of steel would result in the various corrosion products, which depending on the level of the oxidation may have much greater volume than the original iron that gets consumed by the process of corrosion. This volume expansion would be responsible for exerting the expansive radial pressure at the steel-concrete interface resulting in the development of hoop tensile stresses in the surrounding cover concrete. Once the maximum hoop tensile stress exceeds the tensile strength of the concrete, cracking of cover concrete would take place. The cracking begins at the steel-concrete interface and propagates outwards and eventually resulting in the through cracking of the cover concrete. The cover cracking would indicate the loss of the service life for the corrosion-affected structures. In the present paper, analytical models have been developed considering the residual strength of the cracked concrete and the stiffness provided by the combination of the reinforcement and expansive corrosion products. The problem is modeled as a boundary value problem and the governing equations are expressed in terms of the radial displacement. The analytical solutions are presented considering a simple 2-zone model for the cover concrete viz. cracked or uncracked. A sensitivity analysis has also been carried out to show the influence of the various parameters of the proposed models. The time to cover cracking is found to be function of initial material properties of the cover concrete and reinforcement plus corrosion products combine, type of rust products, rate of corrosion and the residual strength of the cover concrete. The calculated cracking times are correlated against the published experimental and analytical reference data.
