Very recently, by employing an addition theorem for the con-fluent hypergeometric function, Paris has obtained a Kummer-type trans-formation for a $_2F_2(x)$ hypergeometric function with general parameters in the form of a sum of $_2F_2(-x)$ functions. The aim of this note is to derive his result without using the addition theorem.

Purpose: The purpose of this study was to identify related factors of stress, social support and rehabilitation motivation of stroke survivors and analyze their relationship. Method: A sample of 106 stroke survivors completed face-to-face interviews. The levels of stress, social support and rehabilitation motivation were measured by the Neuman's stress, Multidimentional Scale Perceived Social Support and Han's Rehabilitation Motivation, respectively. The t-test, ANOVA, and Pearson correlation were conducted using the SPSS 17.0. Results: The mean scores of stress, social support and rehabilitation motivation were 3.3 (SD=0.76), 3.2 (SD=0.88), and 3.4 (SD=0.49) respectively. Compared to stroke survivors who had no spouses, those with spouses had a lower level of stress (t=9.52, p=.003), a higher level of social support (t=7.32, p=.008) and a higher level of rehabilitation motivation (t=15.39, p=.001). The rehabilitation motivation was significantly higher in stroke survivors with higher education (F=5.00, p=.001), more monthly income (F=15.39, p=.001), greater income satisfaction (F=3.80, p=.026), shorter duration of disease (F=3.64, p=.030) and absence of dysarthria (t=6.81, p=.010). Stress, social support and rehabilitation motivation are significantly related with each other. Conclusion: The findings suggest that these significant factors should be considered when caring for stroke survivors.

Let k be a global field of characteristic unequal to two. Let $C:y^2=f(x)$ be a nonsingular projective curve over k, where f(x) is a quartic polynomial over k with nonzero discriminant, and K = k(C) be the function field of C. For each prime spot p on k, let ${\hat{k}}_p$ denote the corresponding completion of k and ${\hat{k}}_p(C)$ the function field of $C{\times}_k{\hat{k}}_p$. Consider the map $$h:Br(K){\rightarrow}{\prod\limits_{\mathfrak{p}}}Br({\hat{k}}_p(C))$$, where p ranges over all the prime spots of k. In this paper, we explicitly describe all the constant classes (coming from Br(k)) lying in the kernel of the map h, which is an obstruction to the Hasse principle for the Brauer groups of the curve. The kernel of h can be expressed in terms of quaternion algebras with their prime spots. We also provide specific examples over ${\mathbb{Q}}$, the rationals, for this kernel.

Purpose: This study was to describe the perception of biomedical ethics in 210 nurses working at a hospital in Busan. Method: Data were collected from September 1st to 9th, 2008 using a 4-point Likert scale which was designed by Kwon. Results: The average score of perception of biomedical ethics was $2.88{\pm}0.22$. The highest score, $3.13{\pm}0.35$, was seen in the category of the ethics for right to life, the lowest, $2.49{\pm}0.33$, was seen in the category of ethics of death. There was no significant difference in perception of biomedical ethics according to marital status, participation in religious activity or career length. There was a significant difference in reproductive ethics according to marital status (F=3.559, p= .001) and participation in religious activity (F=3.914, p= .011). There was a significant difference in ethics of death according to career length (F=3.779, p= .011). Statistically significant differences were shown in ethics for right to life according to the ethical values (F=4.421, p= .005) and attendance of a conference for biomedical ethics (F=4.133, p= .018). The difference of the perception of biomedical ethics was significant in ethical values (F=3.859, p= .010) and attendance of a conference for biomedical ethics (F=3.783, p= .025). Conclusion: Continuing educational programs need to be developed and more reinforced education should be offered.

Purpose: The purpose of this study was to provide basic data which is necessary for educating nursing and medical students for establishing a desirable sense of ethics values Method: In this descriptive research, a total of 140 nursing students and 124 medical students were selected. The tools used for data analysis were descriptive statistics, t-test, one-way ANOVA, and Scheffe test by using SPSS/WIN 12.0 version. Result: When the differences in the consciousness of biomedical ethics of nursing and medical students were compared, statistically significant differences were found in the category of brain death (t=-3.26, p=.001). Statistically significant differences were found in the general characteristics of religion (F=3.05, p=.018), and participation in religious activity (F=3.34, p=.006). Statistically significant differences were found in the characteristics related to the subjects' ethical values such as satisfaction level of a nurse/doctor (F=7.39, p=.000) occupation, the experience of A Patient's Bill of Rights (F=2.97, p=.020), the intention to attend biomedical ethics (F=5.61, p=.000), and the possibility of increasing ethical problems according to the development in the field of medical science (F=7.92, p=.000). Conclusion: An effort should be made to overcome the differences in the perception of biomedical ethics between nursing students and medical students. Moreover, when investigating the course of an integrated education for the establishment of a desirable sense of biomedical ethics, an alternative plan that could promote ethical values must be considered so that the significant variables can promote bioethical perception.
