Purpose: This study is to assess the quality of life(QOL) of hematic cancer survivors after hematopoietic stem cell transplantation(HSCT) and received chemotherapy(RC) to prepare basic information for nursing interventions in order to improve the patients' QOL. Method: The data were collected by self-reporting questionnaire from January to March, 2003 intended for outpatients at the Cancer center of D university hospital in Busan. All 44 of them were diagnosed as hematic cancer and had spent 100 days after getting HSCT and complete remission(CR) throughout RC. The collected data were analyzed with descriptive statistics, t-test, ANOVA using SPSS/WIN 10.0 program. Results: The total mean score of the QOL was moderate. In case of survivors in HSCT, the total mean score of the QOL was $5.81{\pm}1.08$, and that of survivors in RC was $5.94{\pm}1.13$. The facts above has not been considered statistically as the result of analysis of differences in each domain of the QOL depending on the general characteristics of the objects of this study. Conclusion: The total mean score of the QOL was at moderate levels, indicating that the survivors after HSCT and RC were perceiving their QOL as moderate. In the nursing business aspect, the most important thing is to understand the QOL which the 2 groups of the survivors perceive, and the plans of nursing intervention that can be helpful to more qualitative life should be studied constantly.

The material and mechanical properties in the high temperature area of 40 to 100 MPa high strength concrete structural member was identified based on mixing of fiber cocktail and the structural element fire behavior simulation through the finite element analysis method (ABAQUS) was interpreted. The results are as follows. First, it was interpreted that the test specimen with concrete fiber cocktail mixed was more controllable in the maximum shrinkage than the one with concrete fiber cocktail not mixed the controllable range was about 25% to 55%. This means that shrinkage is controllable through mixing of fiber cocktail for the high strength concrete columns. Second, this study didn't consider the explosive spalling by the pore pressure within high strength concrete. If the properties for the pore pressure within high strength concrete is considered and database by strength and by inner temperature of various high strength concrete and steel materials are established in the future, it is interpreted that the technical foundation will be laid for performance based design of fire resistant construction.

The purposes of this study were to examine whether the e-promotion interest was an influencing variable on promotion-acceptance attitudes, browsing, consumer satisfaction and e-loyalty, and to investigate the predictors for e-loyalty of shopping mall according to e-promotion interests. A questionnaire was developed based on the previous researches. Data were obtained from 555 adults who had purchased fashion products in online shopping. Data were analyzed using by factor analysis, Cronbach's alpha, t-test and regression. The results showed that consumers with high e-promotion interests were more likely to accept e-promotions affectively and behaviorally, to have hedonic and utilitarian browsing, to satisfy the online shopping, and to make e-loyalty compared to them with low e-promotion interests. For high interested group in e-promotion, the more cognitive and affective attitudes toward promotion acceptance they were the greater e-loyalty in the context of online shopping for fashion products. Additionally, the more hedonic browsing and satisfy the online shopping they were the greater e-loyalty of shopping mall at Internet. However, for low interested group in e-promotion interests, the more utilitarian browsing and satisfy the online shopping they were the greater e-loyalty of online shopping for fashion products. It implies that consumer' e-promotion interest was an influencing variable on promotion-acceptance attitudes, browsing, consumer satisfaction and e-loyalty in online shopping for fashion products. Consumer satisfaction played an important role for making e-loyalty of fashion shopping malls. These findings are discussed in terms of insights for developing the strategies of encouraging to make the loyalty of shopping mall in the context of purchasing fashion products at Internet.

This study examines the relationships between grandparenting roles, elderly generativity, and depressive symptoms. Data were collected from 129 grandmothers who helped raise grandchildren attending daycare centers. Grandparenting roles were assessed as generational transferers, caretakers, emotional supporters, and educators. Elderly generativity and depressive symptoms were evaluated based on the Loyola Generativity Scale and CES-D (Center for Epidemiological Studies on Depression Scale), respectively. Data were analyzed using t-test, ANOVA, and regression analysis methods. According to the results, grandmothers were most likely to play a role as caretakers, and there were differences across factors correlated with grandparenting roles. More specifically, daily hours spent on grandparenting and years of grandparenting were related to the caretaker role, and a high level of education was related to the educator role. Poor health was correlated with the generational initiator role. According to correlation and regression analyses, grandmothers who had access to more economic resources and who served as educators, emotional supporters, or generation initiators were more likely to show generativity. In addition, the higher the generativity, the less likely the depressive symptom was. These results have important implications for developing programs that can help grandparents raise preschool-aged grandchildren and suggest some interesting avenues for future research.

This study aimed at advanced oxidation of hetero tri-functional reactive dye Acid orange 7 using photo-Fenton conditions in a lab-scale experiment. Decolourisation of Acid Orange 7 dye by Fenton's process was dependent on concentration of Hydrogen peroxide, Ferrous sulphate, pH, and contact time. A $2^3$ factorial design was used to evaluate the effects of these key factors: pH, Fe(II), and $H_2O_2$ concentration, for a dye concentration of 50 mg/L with COD of 340 mg/L at pH 3.0. The response function was removal of colour under optimised conditions; pH 3.0, [Fe(II)] 40.83 mg/L, [$H_2O_2$] 4.97 mmol/L; 13.6 min. of treatment resulting in 100% colour removal. The final COD of treated wastewater was nil suggesting that AOP is a potentially useful process of color removal and dye degradation/mineralisation of effluent having AO7. Minimum contact time for complete decolourisation was at 5 mmol/l $H_2O_2$ concentration. Increase in $FeSO_4$ (mg/l) concentration resulted in decrease of time for complete decolourisation. Box-Behnken Design was used to optimize the process variables. Maximum and minimum levels of pH (3-5), $H_2O_2$ (4-6 mmol/l), $FeSO_4$ (30-46 mg/l) and contact time (5-15 minutes) were used. The statistical analysis revealed a value of 0.88 for coefficient of regression ($R^2$) indicating a good fit of model. Calculated F-value was found higher than the tabulated value confirming to significance of the model. Based on student's t-test, Ferrous sulphate, pH, and contact time have a positive effect on the percent decolourisation of Acid Orange 7.

One of the most important design criteria in military tunnels and armoured doors is to resist the blast loads with minimum structural weight. This can be achieved by using steel sandwich panels. In this paper, the nonlinear behaviour of steel sandwich panels, with different core materials: (1) Hollow (no core material); (2) Rigid Polyurethane Foam (RPF); and (3) Vulcanized Rubber (VR) under free air blast loads, was investigated using detailed 3D nonlinear finite element models in Ansys Autodyn. The accuracy of the finite element model proposed was verified using available experimental test data of a similar steel sandwich panel tested. The results show the developed finite element model can be reliably used to simulate the nonlinear behaviour of the steel sandwich panels under free air blast loads. The verified finite element model was used to examine the different parameters of the steel sandwich panel with different core materials. The result shows that the sandwich panel with RPF core material is more efficient than the VR sandwich panel followed by the Hollow sandwich panels. The average maximum displacement of RPF sandwich panel under different ranges of TNT charge (1 kg to 10 kg at a standoff distance of 1 m) is 49% and 53% less than the VR and Hollow sandwich panels, respectively. Detailed empirical design equations were provided to quantify the maximum deformation of the steel sandwich panels with different core materials and core thickness under a different range of blast loads. The developed equations can be used as a guide for engineer to design steel sandwich panels with RPF and VR core material under a different range of free air blast loads.
