The research was to investigate the effect of quality cognition(usage, medical information, aesthetic, safety) of the web site of the facility on customer loyalty and moderating role of trust variable. The respondents was 201 patients and caregivers. Data were collected from March 1 to 31, 2010 at C university hospital in G city. In relationship between quality cognition of facility web site and customer loyalty, the results of quality cognition on customer loyalty showed 43.1% (F=36.912) in model 1, 46.3%(F=33.454) in model 2, and 46.8%(F=18.580) in model 3. In relationship between web site quality cognition and customer loyalty, moderate effect of trust was not considerable. As results, quality is the leading fact for customer loyalty more than trust. Therefore, customer loyalty leaves its possibility of increment when facility web site is designated depending on medical information, usage and aesthetic.

Objectives : The purpose of this study is to systematically analyze the effect of Tai Chi as therapeutic exercise on depressing blood pressure. Methods : We reviewed articles published in the PubMed, Chinese Academic Journals(CAJ) and five Korean databases. The searching keywords were "Tai chi AND blood pressure" and "Tai chi AND hypertension". We evaluated the quality with Cochrane risk of bias tool. Results : In the 114 articles searched, 7 randomized controlled clinical trials were selected. Yang(楊) style Tai chi, exercising over 30 minutes a time and over three times a week, had an effect on decreasing blood pressure. However, Wu(吳) style Tai chi was not effective in decreasing blood pressure. Conclusions : Usual exercises for hypertension patients should be performed in the form of moderate exercises intensity for 10-26 weeks by 30-60 minute a time, over 3 times a week. The study of Tai Chi on blood pressure needs to follow this criteria in the future.

Purpose: The purpose of this study was to identify the moderating effect of leisure satisfaction on the relationship between job stress and job satisfaction. Methods: A cross-sectional study was performed with 292 nurses having experienced shift work at least for 6 months. Data were collected from August to September in 2014. Descriptive statistics, t-test, correlation coefficient, and hierarchical regression analysis were performed. Results: The study showed that job satisfaction was significantly correlated with job stress (r=.-320, p<.001) and leisure satisfaction (r=.317, p<.001). Leisure satisfaction had a significant moderating effect on the relationship between job stress and job satisfaction (F=25.087, p<.001). Conclusion: This study concluded that the role of leisure satisfaction may moderate the relationship between the two. That is, the nurses who perceived higher satisfaction on their leisure life tend to have higher satisfaction to their job even in stress situation. Therefore, the strategies for improving leisure satisfaction are needed to increase job satisfaction in stressful conditions.

The fracture mechanics analysis of surface cracks in plates and cylindrical geometries is important in the integrity evaluation of flawed structural components. The objective of this paper is, thus, to numerically investigate an interaction effect of two surface cracks in plate and cylindrical geometries. The effect of crack spacing on the magnitude of the stress intensity factor(K) is investigated using the line-spring model. For the case of a finite plate under uniaxial loading, the effect of crack spacing on the K values is negligible. However, for the case of a cylinder under moderate internal pressure, a significant increase in K values is observed at the deepest point of the surface crack.

Flavonoids, a group of low molecular weight phenylbenzopyrones, have various pharmacological properties including antioxidant, anticancer, bactericidal, and anti-inflammatory. We carried out anti-herpetic assays on 18 flavonoids in five classes and a virus-induced cytopathic effect (CPE) inhibitory assay, plaque reduction assay, and yield reduction assay were performed. When flavonoids were applied at various concentrations to Vero cells infected by HSV-1 and 2, most of the f1avonoids showed inhibitory effects on virus-induced CPE. Among the flavonoids, EC, ECG (flavanols), genistein (isoflavone), naringenin (flavanone), and quercetin (flavonol) showed a high level of CPE inhibitory activity. The antiviral activity of flavonoids were also examined by a plaque reduction assay. EC, ECG, galangin, and kaempferol showed a strong antiviral activity, and catechin, EGC, EGCG, naringenin, chrysin, baicalin, fisetin, myricetin, quercetin, and genistein showed moderate inhibitory effects against HSV-1. In these experiments, flavanols and flavonols appeared to be more active than flavones. Furthermore, treatment of Vero cells with ECG and galangin (which previously showed strong antiviral activities) before virus adsorption led to a slight enhancement of inhibition as determined by a yield reduction assay, indicating that an intracellular effect may also be involved.

The pharmacological effects of an Ayurvedic diuretic drug 'Treenoponchomul' (TPM) was investigated in animal model. The pharmacological actions of the test drug along with that of the components thereof, on the Central Nervous System (CNS) were studied. The drug under study TPM showed little effect on the CNS, the same can not be said about the components. The most prominent CNS depressant effect was observed with Saccharum officinarum Linn. (EE) in that it lowered the spontaneous motor activity as well the exploratory -behavior of the animals. An exploration retarding effect of moderate degree, was evident with Imperata cylindrica Beauv. (UU), and Phragmites maxima Blatter & McCann (NN). Although the test drug did not alter the normal locomotor and/ or exploratory behavior of the treated animals, it did significantly (p<0.01) lower the locomotion of the amphetamine induced hyperactive animals. TPM along with its components (especially Desmostachya bipinnata Stapf. Root, KU), significantly reduced the gastro-intestinal motility of the treated animals (p<0.01). The test drug and its components lowered the body weight of the treated animals, on being administered chronically (30 days), with EE being the only exception.

This study was attempted to investigate the effect of inosiplex on the cell-mediated immunity in the patients with lepromatous leprosy. Fourteen patients received inosiplex (6gm/day) for 1 month. About 20% of the patients (3 of 14) showed conversion of the lepromin reaction and bacteriological index was significantly decreased in 3 of 7 patients. However, inosiplex administration had no effect on the lymphocyte blastogenesis to M. leprae. The clinical evolution showed a favorable activity of the drug on cutaneous lesions in some patients. The tolerance of the drug was excellent. No side effects were observed. These results suggest that inosiplex may have a moderate immunopotential value in lepromatous leprosy.

In this paper, nonlinear vibration and post-buckling analysis of beams made of functionally graded materials (FGMs) resting on nonlinear elastic foundation subjected to thermo-mechanical loading are studied. The thermo-mechanical material properties of the beams are assumed to be graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents, and to be temperature-dependent. The assumption of a small strain, moderate deformation is used. Based on Euler-Bernoulli beam theory and von-Karman geometric nonlinearity, the integral partial differential equation of motion is derived. Then this PDE problem which has quadratic and cubic nonlinearities is simplified into an ODE problem by using the Galerkin method. Finally, the governing equation is solved analytically using the variational iteration method (VIM). Some new results for the nonlinear natural frequencies and buckling load of the FG beams such as the influences of thermal effect, the effect of vibration amplitude, elastic coefficients of foundation, axial force, end supports and material inhomogenity are presented for future references. Results show that the thermal loading has a significant effect on the vibration and post-buckling response of FG beams.

Experience of previous earthquakes shows that a considerable portion of concrete precast buildings sustain relatively large damages especially at the beam-column joints where the damages are mostly caused by bar slippage. Precast concrete buildings have a kind of discontinuity in their beam-column joints, so reinforcement details in this area is too important and have a significant effect on the seismic behavior of these structures. In this study, a relatively simple and efficient nonlinear model is proposed to simulate pre- and post-elastic behavior of the joints in usual practice of precast concrete building. In this model, beam and column components are represented by linear elastic elements, dimensions of the joint panel are defined by rigid elements, and effect of slip is taken into account by a nonlinear rotational spring at the end of the beam. The proposed method is validated by experimental results for both internal and external joints. In addition, the seismic behavior of the precast building damaged during Bojnord earthquake 13 May 2017, is investigated by using the proposed model for the beam-column joints. Damage unexpectedly inducing the precast building in the moderate Bojnord earthquake may confirm that bearing capacity of the precast building was underestimated without consideration of joint behavior effect.

Purpose: The purpose of this study was to identify the moderating effect of interpersonal skills on the relationship between childhood emotional trauma and depression. Methods: From June to July, 2017, a convenience sample of 226 nursing students was recruited. Research data were collected through self-report questionnaires and analyzed using SPSS version 22.0. Results: 68.1% (154) respondents experienced emotional abuse, and 48.1% (110) emotional neglect in childhood emotional trauma. The average depression score was 10.76. There were 54.4% (123), 34.5% (78), 12.8% (29), and 7.1% (16) of respondents with mild, moderate, and severe depression, respectively. The average interpersonal skills score was 3.59. There was a significant correlation between childhood emotional trauma (emotional abuse, emotional neglect), interpersonal skills and depression. And the moderating effect of interpersonal skills on the relationship between childhood emotional neglect and depression was significant. Conclusion: Interpersonal skills play a role as a moderating variable influencing the relationship between emotional neglect of childhood emotional trauma and depression, and also reduce the effects of childhood emotional trauma on depression. When developing a depression prevention program for nursing college students, such programs should consider strategies to reduce the negative effects of childhood emotional trauma and to improve interpersonal skills.
