This study was to identify the factors of ethical values in nursing students. The survey was conducted in two nursing colleges (n=180) using self-reported questionnaire. The data were analyzed with descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficient and multiple regression analyses using SPSS/WIN 21 software. Influencing factors of ethical values were empathy(t=3.436, p=.001), teaching method except lecture(t=3.037, p=.003), and curriculum track at high school(t=2.309, p=.022). The model was statistically significant explaining 16.2% of the variance (F=11.185, p<.001). This study suggests that strategies for increasing nursing students' ethical values include reinforcing empathy, utilizing various type of teaching method except lecture in nursing ethics class, and allowing high school students applying to college of nursing regardless of their curriculum track.

본 연구에서는 산화구 방법으로 하수처리를 하는 공공 하수처리장을 선정하여 통계적인 방법으로 처리장의 수질 및 운영의 효율을 분석하였다. 얻어진 수질 데이터는 유입수 및 배출수의 pH, 온도, BOD, SS, T-N, ${NH_4}^+-N$ 및 T-P였다. 데이터 분석은 군집분석, 상관분석, ANOVA 분석, 클러스터 분석으로 수행되었다. 통계분석 결과, 하수 처리장의 유입 유량은 여름에 가장 높았으며 평균 유속은 $3.000m^3/s$이었다. Box plot 결과에 따르면, 하수의 COD, 총인 농도는 계절에 변화에 따라 크게 차이가 없었다. Pearson 상관관계 분석결과는 유입수에서 BOD, COD, T-N 및 T-P 간에 강한 양의 상관관계를 보였다. 계절변화에 따른 BOD와 T-N 농도는 겨울철에 가장 높았고, 계절에 따른 온도의 영향은 COD와 T-P가 가장 높았다. BOD는 수온과 음의 상관관계를 보였으나 HRT, SRT, C/N과 같은 공정인자는 양의 상관관계를 나타내었다. 유입수 온도가 높을수록 BOD 농도가 낮아지는 현상을 보였으며, 체류 시간이 단축될수록 BOD의 처리 효율이 저하되었다. T-N은 효율적인 처리를 위해 긴 체류 시간이 필요했으나 T-P는 공정인자의 변화에 따른 상관관계도에서 다소 적게 나타났다.

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.

Background: The retrospective dosimetry using RTL quartz can be improved by information for an optical sensitivity of sample connected with the equivalent dose determination. Materials and Methods: The quartz sample from a volcanic rock of Japan was used. After correcting the thermal quenching effect, RTL peaks of quartz were separated by the CGCD method cooperated with the general order kinetics. The number of overlapped glow peaks were ascertained by the $T_m-T_{stop}$ method. The optical sensitivity was examined by comparing the change of intensity on RTL glow peaks measured after exposure to light from a solar simulator with various illumination times. Results and Discussion: Seven glow peaks appeared to be overlapped on the RTL glow curve. The general order kinetics model was appropriate to separate glow peaks. After exposure to light from a solar simulator from a few minutes to 416 hr, the signals for peaks P4 and P5 decayed following the form of $f(t)=a_1e^{-{\lambda}1t}$, while the signals for peaks P6 and P7 decayed by the form of $f(t) = a_1e^{-{\lambda}1t}+a_2e^{-{\lambda}2t}+a_3e^{-{\lambda}3t}$. Conclusion: For dosimetric peaks, the times taken to reduce the RTL signal to half of its initial value were 70 sec for the peak P4, 54 s for the peak P5, 9,840 sec for the peak P6 and 26,580 sec for the peak P7, respectively. We conclude that the optical sensitivity of peaks P4, and P5 gives much higher than that of peaks P6 and P7.

Purpose: This study was designed to investigate effect of sensory stimulation on the mother-infant interaction in premature infants. Method: The subjects of this study consisted of 36 pairs of premature infants and their mothers from NICU of one university hospital located in Taegu, 18 pairs for intervention group and 18 pairs for control group. The data were collected from May, 1999 to October, 2000. For the intervention group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00-11:00 in the morning and 7:00-8:00 in the afternoon by researcher and mother). To determine mother and infant interaction during feeding, tool developed by Kim Mi-Ye(1999) was used. Collected data were analyzed with SAS program using chi-square test and t-test. Result: Significant differences were found in mother-infant interaction between two groups(t=-5.38, p=.00). It indicates that sensory stimulation was effective in improving mother-infant interaction. In the aspects of the quality of mother-infant interaction, sensory stimulation was most effective in improving sensitivity to mother and infant's synchronic behaviors(t=-5.43. p=.00) and followed by growth fostering(t=-5.07, p=.00), sensitivity to infant's cues(t=-4.53, p=.00), clarity of infant's cues(t=-3.03, p=.00) and responsiveness to the mother's behaviors(t=-2.14, p= 0.04). Conclusion: Based on the result of this study, it is suggested that maternally administered sensory stimulation should be applied clinical practice to improve interaction of premature infants and their mothers.
