  • This study investigates the actual hospital-clothes consumption experience of consumers according to gender and age. An all age survey was conducted among male and female ex-patients in Korea nationally. From data collected during April and May 2009, a total of 513 responses were analyzed using descriptive statistics, chi-square analysis, two-way ANOVA, and MANOVA using SPSS 10.1.4. The results are as follows. The hospitalization ratio was higher in the male group than in the female group and increased with age. Many hospitalizations were taken to the department of orthopedics, internal treatment, obstetrics and gynecology, and surgery. The satisfaction with patient gowns was low regarding size, fabric touch, color and pattern, Psychological comfort, and holistic satisfaction, Specifically, the stiffness of the fabric, cheerless colors, and the limited number of sizes were the main complaints; size dissatisfaction was expressed strongly by females. About 35% of respondents showed a positive attitude to wear premium patient gowns. Various medical supplies were used and different items were utilized according to gender and age of patients. Uncomfortableness of medical supplies were highly related to laundry and fabric touch.

  • We analyzed antioxidant and quinone reductase (QR) inductive activities of various organs of pepper for utilizing by-product of them. Peppers were separated into fruits, roots, stems, and leaves and extracted with methanol for the analysis. As a result, pepper leaves showed higher phenol content than other organs. Using the DPPH assay, there was not considerably different activity depending on pepper organs, but pepper leaves showed significantly higher antioxidant activity using the ABTS assay. In FTC and TBA assay, stems and leaves showed significantly higher lipidperoxidation inhibitory activity. In QR inductive assay, pepper tissues showed different QR inductive activity: leaves>roots>>stems>fruits. In addition, pepper leaves showed highest antiproliferation activity on hepa1c1c7 among pepper tissues in $50-200\;{\mu}g/mL$. These results indicate that pepper leaves have high potential to be a good functional food material due to high QR inductive and antioxidant activities.

  • This study was done to evaluate the antioxidant effect of Crataegi Fructus (CF) extract on the oxidative stress induced by reactive oxygen species (ROS), The human skin fibroblasts (Detroit 551) were cultured with various concentrations of hydrogen peroxide $(H_2O_2)$. The cytotoxicity of $H_2O_2-induced$ oxidative stress was performed by XTT assay for the cell viability according to the dose- and time-dependent treatment. For the protective effect of CF extract on $H_2O_2-mediated$ oxidative stress, cell viability, lactate dehydroganase (LDH) activity, and ferric thiocyanate (FTC) assay for the inhibitive activity of lipid peroxidation on CF extract were carried out. In this study, $H_2O_2-mediated$ oxidative stress was decreased cell viability dose-, and time-dependent manner and increased LDH activity compared with the control in these cultures. In the protective effect, CF extract increased cell viability and decreased LDH activity on $H_2O_2-mediated$ oxidative stress, especially, CF extract has antioxidant effect by the showing the inhibitive activity of lipid peroxidation by FTC assay. From these results, It is suggested that $H_2O_2-mediated$ oxidative stress was highly toxic, and also, CF extract showed the protective effect on $H_2O_2-mediated$ oxidative stress by showing the increased cell viability, decreased LDH activity and lipid peroxidation inhibition in these cultures.

  • Purpose: Definite diagnosis of follicular thyroid carcinoma (FTC) is based on the presence of capsular or vascular invasion. To date, no reliable and practical method has been introduced to discriminate this malignant neoplasm from follicular thyroid adenoma (FTA) in fine needle aspiration biopsy material. Matrix metalloproteinase-2 (MMP-2), by degrading extracellular matrix, and caspase-3, by induction of apoptosis, have been shown to play important roles in carcinogenesis and aggressive behavior in many tumor types. The aim of this study was to examine expression of MMP-2 and caspase-3 in thyroid follicular neoplasms and to determine their usefulness for differential diagnosis. Method: Sixty FTAs and 41 FTCs were analysed immunohistochemically for MMP-2 and caspase-3. Result: MMP-2 was positive in 4 FTCs (9.8%), but in none of FTAs, with statistical significance (p= 0.025). Caspase-3 was positive in 30 (50%) of FTAs and in 27 (65.9%) of FTCs. Conclusion: Our results show MMP-2 expression only in FTCs and suggest that this protein may be a useful marker to confirm diagnosis of FTC versus FTA with 100% specificity and 100% predictive value of a positive test. We failed to show any differential diagnostic value for caspase-3 in thyroid follicular neoplasms.

  • The determination of the mixture parameters of stabilization has become a great concern in geotechnical applications. This paper presents an effort about the application of artificial intelligence (AI) techniques including radial basis neural network (RBNN), multi-layer perceptrons (MLP), generalized regression neural network (GRNN) and adaptive neuro-fuzzy inference system (ANFIS) in order to predict the unconfined compressive strength (UCS) of silty soil stabilized with bottom ash (BA), jute fiber (JF) and steel fiber (SF) under different freeze-thaw cycles (FTC). The dosages of the stabilizers and number of freeze-thaw cycles were employed as input (predictor) variables and the UCS values as output variable. For understanding the dominant parameter of the predictor variables on the UCS of stabilized soil, a sensitivity analysis has also been performed. The performance measures of root mean square error (RMSE), mean absolute error (MAE) and determination coefficient ($R^2$) were used for the evaluations of the prediction accuracy and applicability of the employed models. The results indicate that the predictions due to all AI techniques employed are significantly correlated with the measured UCS ($p{\leq}0.05$). They also perform better predictions than nonlinear regression (NLR) in terms of the performance measures. It is found from the model performances that RBNN approach within AI techniques yields the highest satisfactory results (RMSE = 55.4 kPa, MAE = 45.1 kPa, and $R^2=0.988$). The sensitivity analysis demonstrates that the JF inclusion within the input predictors is the most effective parameter on the UCS responses, followed by FTC.

  • The structure and material of Mang-geon from excavated tomb of Yi-ikjung in 1700', Seoul, were analyzed and identified. The Mang-geon was worn by Yi-ikjung when it is found. Until now, it is know that Mang-geon is made of horsehair, but it find out to be made of silk threads. This result verified the presence of 'sa-kyul Mang-geon' which been estimated to used only for document records. This proves Mang-geon has been produced in the silk threads as well as horsehair and human hair. The front and back of the Mang-geon was made of intertwisted silk threads by using simple linking method. Dang is constructed of looped linking method. The size of Dang is wider, which give greater flexibility to wrap top of head.

  • A phytochemical investigation on the methanolic extract of Cosmos caudatus has led to the isolation of quercetin $3-O-{\beta}-D-arabinofuranoside$ (1), quercetin $3-O-{\beta}-D-rhamnoside$ (2), quercetin $3-O-{\alpha]-D-glucoside$ (3) and quercetin (4). These compounds were shown to be the antioxidative constituents of the plant when evaluated using the ferric thiocyanate (FTC) and thiobarbituric acid (TBA), and radical scavengers based on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assays.

  • A natural way to cope with fault tolerant control (FTC) problems is to modify the control parameters according to an online identification of the system parameters when a fault occurs. However. due to not only difficulties Inherent to the online multivariable identification in closed-loop systems, such as modeling errors, noise or the lack of excitation signals, but also long time requirement to identify the post-fault system and implemeutation of control problems during the identification process, we propose an alternative approach based on the observer-based fault detection and isolation (FDI) and model reference adaptive control (MRAC). The proposed robust fault diagnosis method is based on a bank of observers. We also propose a model reference adaptive control with changeable reference models according to the occurred faults. Simulation results of a flight control example show the validity and applicability of the proposed algorithms.
