  • Purpose: The purpose of this study was to identify the death orientation of college student nurses and to evaluate the effectiveness in death orientation of a class on 'hospice care'. this was done by investigating the difference between the death orientation before and after the class. Method: The instrument used in this Investigation was the death orientation scale developed by Thorson and Powell (1988). The subjects of the study were the 47 college student nurses in a 'hospice care' class. The research was carried out between March 2, 2001, when the class began, and June 21, 2001 when the class ended The collected data were examined using arithmetic mean, percentage, t-test, ANOVA. Result: The results of the study are as follows : 1. The average death orientation score of the subjects before the class was 2.80. 2. There were a significant difference in the death orientation scores before and after the class (p<0.001). Before the class, 'hospice care', the students had an average score of 2,80. Their average score decreased to 2.55 after the class. Of 25 death orientation items on the scale, 14 items decreased significantly after the class as compared to before the class. 3. According to personal attributes (religion. the existence of religion, the experience of a death in recently) of subjects, there were no significant statistical differences in death orientation (p>0.05).

  • In this study, the fiber orientation distribution (FOD) is investigated using both micro-CT (computerized tomography) and image analysis of physically cut specimens prepared from Polyvinyl Alcohol (PVA) fiber reinforced cemented Toyoura sand. The micro-CT images of the fiber reinforced cemented sand specimens were visualized in horizontal and vertical sections. Scans were obtained using a frame rate of two frames and an exposure time of 500 milliseconds. The number of images was set to optimize and typically resulted in approximately 3000 images. Then, the angles of the fibers for horizontal sections and in vertical section were calculated using the VGStudio MAX software. The number of fibers intersecting horizontal and vertical sections are counted using these images. A similar approach was used for physically cut specimens. The variation of results of fiber orientation between micro-CT scans and visual count were approximately 4-8%. The micro-CT scans were able to precisely investigate the fiber orientation distribution of fibers in these samples. The results show that 85-90% of the PVA fibers are oriented between ±30° of horizontal, and approximately 95% of fibers have an orientation that lies within ±45° of the horizontal plane. Finally, a comparison of experimental results with the generalized fiber orientation distribution function 𝜌(θ) is presented for isotropic and anisotropic distribution in fiber reinforced cemented Toyoura sand specimens. Experimentally, it can be seen that the average ratio of the number of fibers intersecting the finite area on a vertical plane to number of fibers intersecting the finite area on a horizontal plane (NVtot/NHtot) cut through a sample varies from 2.08 to 2.12 (an average ratio of 2.10 is obtained in this study). Based up on the analytical predictions, it can be seen that the average NVtot/NHtot ratio varies from 2.13 to 2.17 for varying n values (an average ratio of 2.15).

  • The major threat of geometric manipulations is that they change the positions of watermarks, therefore the detection process fails to extract watermark properly. Since they cause the same effects on the host image as watermarks simultaneously, evaluating the distorted host image can be helpful to measure the nature of distortions. In this paper, we propose a geometrical distortion-resilient watermarking algorithm based on this property. Firstly we evaluate the orientation of a host image by filtering it with directional Gabor kernels, then we insert embedding pattern aligned to the estimated orientation. In its detection step, we evaluate the orientation again by Gabor filtering, then simply project and average the projected value to obtain a 1-D projection average pattern. Finally, auto-correlation function of the 1-D projection average pattern identifies periodic peaks. Analysed are experimental results against geometrical attacks including aspect ratio changes.

  • Objective : The purpose of this study was to investigate the perception of death in paramedic student. The results of this study will help develop education program for death orientation, paramedic students education and practice. Methods : A total of 201 paramedic students filled out the questionnaire. The perception of death was examined using questionnaires designed for examining Death Orientation. The data were analyzed with SPSS 18.0 statistics program for frequency, percentage, average, standard deviation, t-test, ANOVA, cronbach alpha coefficient, factor analysis. cronbach alpha coefficient was .866. Results : The paramedic students' got a score of $2.35({\pm}.48)$ on the Orientation on death as average. The reason is that death is not yet pressing them at all and ahead of their lives they have many days to live. With respect to the Death Orientation, significant differences was found in experience of death(t=2.318, p=.021). Group of death experience was higher than group of no death experience. In view of the attitude on afterlife, students responded no afterlife(24.9%), unknown after death(22.4%). Conclusion : The results of this study suggest that paramedic curriculum should include education program on death and improve quality of prehospital care. Additional studies are needed to establish death education for paramedic.

  • The purpose of this study was to examine university students' consumption-orientation and attitude toward conspicuous consumption as well as to identify the factors that are most influential on consumption-orientation and conspicuous consumption behavior. The major findings of this study are summarized below. First, the average scores of consumption-orientation and conspicuous consumption were 2.71 and 3.15 respectively, on a 5 point scale. Second, the most influential factor on university students' consumption-orientation was friends' influence. Third, the most influential factor on conspicuous consumption was students' perceived social status. Fourth, conspicuous consumption tendency and consumption-orientation were significantly higher for those students with larger amount of allowances, female students, or the students who are working. Fifth, the university students' consumption-orientation and conspicuous consumption tendency were significantly higher for the students whose parents' child-rearing style is inconsistent or excessive investment. Finally, the consumption orientation has a significant positive relationship with conspicuous consumption.

  • This study investigates the relevance between the subjective age and clothing shopping orientation by adults women located in the cities of Seoul and Gyeonggi. The results are following. First, subjective age was identified with interest age, look age, and physical age. Customers were segmented into following five subdivisions: young activity group, actual age group, young appearance group, physical aging group and youth-oriented group. When the study examined differences between real age and subjective age, the study could see that they perceived themselves younger four years than real age- 50s: 7 years, 40s: 5 years, the latter half of 30s: 2.7 years and the former half of 30s: 1.7 years. Second, clothing shopping orientation was identified with planned shopping orientation, leisure shopping orientation, loyal shopping orientation, economic shopping orientation and convenient shopping orientation. Customers were segmented into following three subdivisions: shopping low-involved group, loyal leisure group and planned leisure oriented group. Third, interest age was of no relevance to clothing shopping orientation. On the other hand, look age had negative correlation with leisure shopping orientation and convenient shopping orientation and physical age had a negative relationship with leisure shopping orientation and loyal shopping orientation but had positive correlation with economic shopping orientation. Fourth, in clothing purchase, clothing purchase answerers who were younger five years than actual age had the highest frequency. It means that they purchase clothing according to subjective age perceived younger four years on average.

  • The purposes of this study were to classify adolescents by their lifestyles and to investigate the differences in clothing purchase behavior among lifestyle groups. The data were obtained from questionnaire completed 341 adolescents in Daegu area. The SPSS package was used for data analysis which included frequency, factor analysis, cluster analysis, ${\chi}^2$ test, ANOVA, and Scheffe test. Lifestyles of adolescents were categorized into five factors such as clothing hedonic shopping orientation, positive activity, material orientation, frugality, digital orientation. Three clusters (achievement orientation group, ordinary group, economic orientation group) were developed by five factors of lifestyles. While the achievement orientation group had the highest purchase motives and used the most information sources, the economic orientation group had the lowest purchasing motives and used the least information sources. There were significant differences in clothing purchase frequency and average clothing expenditure among three clusters.

  • Structural studies of series of 'as spun' and drawn PEEK fibers have been carried out using X-ray diffraction and optical microscopy techniques. The analysis of results suggest that fibers produced at a constant draw ratio with increasing draw temperatures show enhanced orientation and crystalline behaviour. The resolved equatorial and meridional traces provide additional structural parameters in terms of crystallinity, crystallite size, and crystallite thickness. It is concluded that drawing at a temperature below $T_g(i.e.,\;144^{\circ}C)$ results in poorly oriented non-crystalline materials, whereas drawing above $T_g$ results in highly oriented semi crystalline materials. Additional drawing proved to increase the overall orientation with slight improvements in lateral order of the chain molecules. Quantitative analysis revealed that the crystallite size increases with increasing drawing temperature. The results also revealed the increased crystallite size upon additional drawing. Crystalline orientation parameter, $_c$, suggests almost perfect orientation. In all cases, the amorphous orientation is found to be lower than the overall orientation parameter obtained from the optical birefringence. As a result of additional drawing, crystalline orientation was found to increase slightly but the increase in the orientation of non-crystalline material was found to be substantial. An average crystalline density was determined from the orthorhombic unit cell dimensions. It was found to vary as a result of processing conditions. It was also found that the value of the maximum birefringence shows heavy dependence on the chain conformation.

  • The surface and edge structure of OSB is defined by surface strand orientation and strand mat thickness variation parallel to the length of the panel using video-microscope. The bending strength of OSB was correlated with surface strand orientation and decreased with increasing the orientation angle in the direction parallel to length of the panel. Average strand mat thickness variation parallel to the length of the panel did not influence the bending strength, but the bonding characteristics among the outermost strands affects the bending strength of OSB. Hankinson formula can be used to predicts the MOE according to strand orientation in the surface of OSB, and more precise strand alignment and reducing thickness variation should be important in the structural performance of OSB panels.
