Purpose: This study compared the pain and skin reactions of neonates according to the method of removing the adhesive eyepatch used for phototherapy. Methods: The subjects included 20 neonates admitted at C University Hospital. In group 1 (n=10), DuoDERM dressing was attached under the adhesive eyepatch, which was removed with water, while in group 2 (n=10), the eyepatch was attached on the skin and removed with oil. Heart rate, oxygen saturation, the Neonatal Infant Pain Scale (NIPS), crying time were measured. Data were analyzed using repeated-measures analysis of variance. Results: No interaction was found between group and timing for heart rate and oxygen saturation. In group 1, the NIPS score was higher and the crying time was longer than in group 2. No difference was observed in the erythema score between the groups. Conclusion: Removing the adhesive eyepatch using oil can be used as a nursing intervention to reduce pain and improve comfort in neonates.

The central problem of purchasing houses is choice, which is accompanied by perception of risk. Perceived risk is defined as a risk perceived by a consumer subjectively in choice situations. The components of perceived risk are uncertainty and consequence. There are seven types of perceived risk in purchasing houses. Those are financial risk, functional risk, social risk, psychological risk, physical risk, time risk and future opportunity lost risk. The empirical survey about comsumer's purchasing Public Apartment suggests : 1) In general, rspondents perceive relatively high risk in purchasig Public Apartment. 2) Of seven risk types, financial, functionalm, future opportunity lost, time, and social risk correlate highest with overall perceived risk and explain the variance of it. 3) Physical and psychological risks don't correlate significantly with overall perceived risk. From the findings in empirical analysis, consumers are recommended to device riskreduction activities in purchasing Public Apartment. 1. Active information search is needed in purchasing Public Apartment in order to reduce overall perceived risk. 2. Housing concept should change from ownership to rental thinking. 3. Consumers should be accustomed to Housing Loans by bank. 4. Purchasing goals should be established clearly before purchasing houses. 5. Careful deliberation is required and informations from personal sources are useful.

This paper reports briefly on the computational results of a turbulent Rayleigh-Benard convection with the elliptic-blending second-moment closure (EBM). The primary emphasis of the study is placed on an investigation of accuracy and numerical stability of the elliptic-blending second-moment closure for the turbulent Rayleigh-Benard convection. The turbulent heat fluxes in this study are treated by the algebraic flux model with the temperature variance and molecular dissipation rate of turbulent heat flux. The model is applied to the prediction of the turbulent Rayleigh-Benard convection for Rayleigh numbers ranging from $Ra=2{\times}10^6$ to $Ra=10^9$, and the computed results are compared with the previous experimental correlations, T-RANS and LES results. The predicted cell-averaged Nusselt number follows the correlation by Peng et al.(2006) ($Nu=0.162Ra^{0.286}$) in the 'soft' convective turbulence region ($2{\times}10^6{\leq}Ra{\leq}4{\times}10^7$) and it follows the experimental correlation by Niemela et al. (2000) ($Nu=0.124Ra^{0.309}$) in the 'hard' convective tubulence region ($10^8{\leq}Ra{\leq}10^9$) within 5% accuracy. This results show that the elliptic-blending second-moment closure with an algebraic flux model predicts very accurately the Rayleigh Benard convection.

Purpose: This study was done to identify factors predicting sick-role behavioral compliance in hemodialysis patients. Methods: The subjects were 133 patients from outpatient dialysis clinics at seven major general hospitals located in D and P cities. Data were collected by self-report questionnaires. For data analysis, SPSS/WIN 14.0 program was utilized including one-way ANOVA, independent t-test, Pearson correlation coefficients, and stepwise multiple regression. Results: This study showed a positive correlation between sick-role behavioral compliance and social support (r=.29 p<.001), knowledge (r=.31 p<.001), self-efficacy (r=.52, p<.001) and age (r=.21, p=.015). The factors predicting sick-role behavioral compliance were self-efficacy (${\beta}$=.46), knowledge (${\beta}$=.25), and age (${\beta}$=.18). These factors accounted for 36% of the variance of sick-role behavioral compliance in hemodialysis patients. Conclusion: The results indicate that it is necessary to increase self-efficacy and knowledge in order to improve sick-role behavioral compliance in hemodialysis patients.

Purpose: This study was designed to identify the factors that influenced the decision to have a colonoscopy. Methods: The sample was one hundred ninety four subjects who completed a self administrated survey. The survey posed questions of self-efficacy scale, fatalism scale and an intention scale. Data were analyzed with descriptive and inferential statistics including t-test, ANOVA, Pearson's correlation and multiple regression analysis. Results: There were statistically significant differences among the intention of having a colonoscopy and age, educational background, occupation and income. There was a statistically significant positive correlation between self-efficacy and intention of having a colonoscopy. In contrast, there was a negative correlation between fatalism and decision to have a colonoscopy. Self-efficacy, income and age were significant predictors of the decision to have a colonoscopy; accounting for 44.3% of the total variance. Conclusion: Self-efficacy and fatalism were influence the decision to have a colonoscopy. As a result of these, it may be useful to develop strategies to foster decision making to have a colonoscopy utilizing the findings from this study.

Objective: This study aimed to determine the efficacy of flexible pole training combined with lumbar stabilization in improving trunk muscle activities and to investigate the difference according to posture in young adults. Methods: Twenty-five participants were enrolled in this study. The subjects were randomly allocated into either the flexible pole group or the rigid pole group. Participants performed lumbar stabilization exercises on quadruped and curl-up, with the flexible pole or rigid pole. Electromyography was used to assess the percent maximal voluntary isometric contracion (%MVIC) of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spine (ES) muscles. All participants completed one 30-minute session per day, 3 days per week, for 6 weeks. The evaluation was performed before and 6 weeks after the training, and follow-up. The data were analyzed using independent t-test and two-way repeated measure analysis of variance to determine the statistical significance. Results: The flexible pole in curl-up showed significant differences in EO and IO muscle activities compared with the rigid pole. The flexible pole in quadruped showed significant differences in IO and ES muscle activities compared with the rigid pole. The RA, EO, IO, and ES muscle activities of both groups were significantly higher after 6 weeks training. Conclusion: The flexible pole in curl-up and quadruped showed an improvement in trunk muscle activation. The flexible pole combined with lumbar stabilization will be useful as an exercise tool to improve activity of trunk muscles.

In this paper the cure cycle of carbon fiber/phenolic resin was investigated by the Taguchi Method in an experimental design. Experiments were systematically performed using $L_{18}(2^1 \times 3_7)$ orthorgonal array table of the experimental design. In the experimental design, eight compression molding parameters (heating rate, pressing temperature, pressing rate, molding pressure, curing temperature, dwell time at curing temperature, cooling rate and degassing) were considered and the effects of the parameters on the flexural strength and the apparent porosity of carbon fiber/phenolic composites were investigated. The analysis of variance for the experimental results indicated that molding pressure and curing temperature are the most significant parmeters in the flexural strength and the apparent porosity of carbon fiber/phenolic resin composites, respectively.
