국내에는 17,500여개의 농업용 저수지가 전국적으로 분포하고 있다. 이들 저수지의 대부분은 1945년 이전에 설치되어 경과년수가 70년 이상된 저수지가 전체의 약 52%에 달하며, 1962년 이전에 설치되어 50년 이상된 저수지는 전체의 68.3%에 이르고 있다. 국내 약 70%에 해당하는 저수지는 50년이 넘은 노후화된 저수지로 오염물질의 장기간의 퇴적으로 인해 수용적이 많이 줄었고, 퇴적층의 오염물질 재용출로 인해 호소의 수질악화에 상당한 영향을 주고 있을 것으로 추정된다. 따라서 본 연구에서는 호소 설치 경과년수와 수질간의 상관성을 알아보기 위하여 상관분석을 실시하였고, 일원분산분석과 Scheffe Test를 통해 경과년수에 따라 호소 수질에 유의한 차이가 있는 지에 대해서 살펴보았다. 저수지 설치 경과년수와 수질항목 pH, EC, DO, SS, COD, TN, TP, Chl-a와의 상관성을 분석한 결과, DO를 제외한 모든 항목에서 10~40%의 정(+)의 상관성을 보여 저수지 준공년도가 오래된 것일수록 수질오염도가 높아지는 것으로 나타났다. 농업용 저수지의 준공 경과년수 구간에 따른 수질이 통계적으로 유의한 차이가 있는가를 알아보기 위하여 호소의 경과년수를 70년 이상($Y{\geq}70$), 50년 이상 70년 미만($50{\leq}Y$<70), 30년 이상 50년 미만($30{\leq}Y$<50), 10년 이상 30년 미만($10{\leq}Y$<30), 10년 미만(Y<10) 등 5개 구간으로 분류하여 일원분산분석을 실시하였다. 통계분석에 사용된 자료는 2013년도 농업용수 수질측정망 조사자료 3,175개를 이용하였다. 수온, pH, EC, COD, TN, TP, SS, Chl-a 등 거의 모든 수질항목에서 유의수준 p<0.001 에서 통계적으로 유의한 차이가 있는 것으로 나타났다. 사후검정인 Scheffe Test를 실시한 결과, DO를 제외한 모든 항목에서 70년 이상 된 구간($Y{\geq}70$)과 50년이상 70년 미만(의 구간에서 다른 구간에 비해 다소 높은 값을 보였고, 준공 경과년수가 작아질수록 농도가 점차적으로 낮아지는 경향을 보였다. 이러한 결과는 저수지가 설치된 지 오래되어 노후화가 진행될수록 수질오염도 높아지는 것을 알 수 있었다.

This study was conducted to identify the effects of repeated cardiopulmonary resuscitation (CPR) training using smart learning on nursing students' knowledge, self-efficacy, and clinical competency. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 102 nursing college students who had received CPR training for 6 months. The CPR training was divided into smart learning, lecture education, and practical education. Data were collected from November to December, 2016 and analyzed by descriptive statistics, ${\chi}^2$-test, t-test and one way ANOVA using the SPSS/WIN 21.0 program. The scores of cardiopulmonary resuscitation knowledge were higher in the lecture education group than the practical education group and the smart learning group. Scheffe's post hoc test revealed a statistically significant difference among groups (F=8.23, p=<.001). The self-efficacy of the practical education group was higher than that of the lecture education group and smart learning group, but this difference was not significant (F=2.46, p=.091). The clinical competency of the practical education group and smart learning group were higher than that of the lecture education group. Scheffe's post hoc test revealed that the value of clinical competency differed significantly among groups (F=59.90, p=<.001). Overall, the results showed that effective education differs based on nursing students' knowledge, self-efficacy, ad clinical competency. Combination training would be required for more effective repeated cardiopulmonary resuscitation training.

This study examined the difference between mindfulness and psychological well-being of art psychotherapists according to their demographic characteristics. The subjects were 127 art psychotherapists working at counseling centers in Ulsan metropolitan city. Statistical software R was used for frequency analysis, factor analysis, reliability analysis, independent-sample T-test, and one-way ANOVA. A Scheffe test was used for post hoc analysis. The results showed that the difference in mindfulness of art psychotherapists was significant in age and at peer supervision and case study meanings in supervision type only. Second, the difference in the psychological well-being of art psychotherapists was significant at peer supervision and case study meetings in supervision type only. This means that the more art psychotherapists experience peer supervision and case conferences, the more they perceive mindfulness and psychological well-being. These results suggest that age and supervision type are important for the art psychotherapists' mindfulness and psychological well-being. Therefore, to improve artistic psychotherapists' mindfulness and psychological well-being, it is necessary to systematically develop and operate support programs for each developmental stage to improve artistic psychotherapists' demographic characteristics and professional development.
