This study examined how walking moderates the influence of depression on quality of life in elderly. Data of the study were analysed using the sixth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2014). The subjects were elderly aged 65 years or more and the number of the sample was 1,263. Using hierarchial regression analysis, walking as a moderator of the depression and quality of life relationship was examined. Quality of life for elderly showed significant differences according to sex(t=8.26, p<.001), age(t=5.19, p<.001), number of chronic disease(F=37.88, p<.001), depression(t=9.62, p<.001) and walking per week (t=47.36, p<.001). Walking moderated the relationship between depression and quality of life in elderly. Based on these findings, the enhancement of walking in depressed elderly is recommended to promote the quality of life.

최근 이상기후로 인한 집중호우의 증가로 인해 하천의 홍수방어능력을 초과하는 침수피해가 급증하고 있다. 특히, 제주도는 태풍의 길목에 위치하고 있는 강우량이 약 2,061mm에 달하는 우리나라 최다우 지역으로 평시에는 건천인 상태의 하천이 집중호우 시 급격한 유출 발생으로 하류도심지역에 하천 범람으로 인한 많은 피해가 발생하고 있다. 제주도에서는 이를 방어하기 위해 하도 내 첨두 홍수량을 조절하여 하류지역의 피해를 경감시키기 위한 구조물인 저류지를 상류에 설치하여 운영하고 있다. 하지만 저류지의 건설을 통한 실제 홍수조절효과에 대한 정량적인 분석은 미흡한 실정이다. 이에 본 연구에서는 태풍 '나리' 때 가장 큰 피해가 발생한 한천의 한천1, 2 저류지를 대상지역으로 선정하여 2차원 수치모형인 Nays2d Flood 모형을 활용한 한천 저류지의 운영에 따른 홍수조절효과를 분석하였다. 지형자료는 드론을 활용하여 측정된 약 7cm 간격의 정밀한 하상 측량자료를 사용하였고, 태풍 '차바' 발생 시 계측된 저류지내의 수심 측정 센서 자료를 활용하여 모형의 검보정을 수행하였다. 보정된 모의결과를 활용하여 태풍 '차바' 때의 저류지가 활용되는 모습을 재현할 수 있었고, 이를 통해서 현재 설치된 저류지의 구조적인 문제점과 운영방법에 따른 홍수조절효과 개선방안을 제시하고자 하였다. 또한 저류지 설계 시 사용된 100년 빈도의 설계 홍수량을 바탕으로 모의를 수행하여, 기존에 제시된 한천저류지의 홍수 저감량과의 비교를 통해서 실제 저류지의 운영에 따른 홍수조절효과를 정량적으로 분석하였다.

We Investigated the Two Additional Effects Regarding the Causal Relationship between the Perceived Risks of cloud Services on the Intention to use the Abandonment Option. First, we Empirically Tested the Moderation Effect of IS Maturity on the Causal Relationship between these Two Variables. Second, we also Investigated the Mediation Effect of Cloud Service Satisfaction on the same Causal Relationship. We could find the Moderation and Mediation Effect only on the Influence of Relational Risk (Which Occurs from the Power Abuse of Cloud Service Providers) on the Intention to sue the Abandonment Option. So, we have better Understanding when and how the Abandonment Option is Attractive in Reducing the Potential Influence of the Relational Risk in using the Cloud Services.

The purpose of this research was to identify the relationship between specific personality characteristics and maladaptive social behaviors in order to contribute to development of a pragmatic intervention for the prevention of sexual aggression. This was accomplished by examining the mediating effects of entitlement rage (K-PNI) or sociosexuality (K-MSAS) on sexual aggression, and moderating effects of cognitive emotion regulation strategies (K-CERQ) or state empathy (K-CMEM) on sexual aggression in narcissistic men. Data were obtained from male college students (n = 264) who completed self-report questionnaires, such as K-NPI and K-CMEM, and hierarchical regression analysis was applied to examine these relationships. Both entitlement rage and cognitive emotion regulation strategies were found to be unassociated with sexual aggression. Rather, sociosexuality was the mediating factor between narcissism and sexual aggression, Whereas state empathy was a moderating factor between narcissism and sexual aggression. These findings indicate a tendency for sociosexuality to increase sexual aggression in males. However, individuals with low state empathy are more likely to show sexual aggression than those with high state empathy, indicating that intervention for increased state empathy may be a more effective treatment than cognitive emotion regulation strategies.

This study aims to provide the fundamental data of an efficient grading system after identifying the mediate and moderating effects of self-participation regarding the impact of education service quality on student satisfaction. To achieve the purpose of the study, SPSS 18.0 statistic program was used to conduct the frequency, factor and correlation analysis while targeting 310 students majoring in food service and culinary arts & science in 2 and 4 year universities in Busan area. Specifically, the mediate and moderating effects of self-participation were examined in accordance with three-stage regression analysis and hierarchical regression analysis, respectively. The results of analyses suggested that there was the positive correlation between student satisfaction and education service quality, and the student satisfaction was correlated with self-participation in the entire variables, except for the welfare service. The self-participation didn't have any mediate effect, since the ratio of the student satisfaction to the education service quality with self-participation turned out to be p<0.01. The self-participation had moderating effects on student satisfaction, with the $R^2$ being increased by 0.032, from 0.537 to 0.569. However, it was only partial moderating effects because the self-participation, when along with laboratory environment, was not positively effective in terms of the statistic variables.

The purpose of this study was to examine how the interaction between organizational culture and organizational communication factors on the effectiveness of a set of organizations has an effect on organizational effectiveness. For the empirical analysis of this study, we conducted a questionnaire survey on the subjects who participated in the core job training course of SMEs. To test the hypothesis of this study, we analyzed the moderating effects of organizational communication on the relationship between organizational culture type and organizational effectiveness by statistical analysis, correlation analysis, regression analysis, multiple regression analysis, and control effect analysis through statistical program SPSS 20.0. The results of the empirical analysis show that organizational culture type positively influences organizational commitment and job satisfaction, but organizational culture has a positive effect on organizational culture. It exhibited a positive moderating effect. Therefore, this study reviewed the theoretical validity of existing studies by analyzing the moderating effects of organizational communication in the relationship between organizational culture type and organizational effectiveness. On the other hand, the empirical analysis of the interaction effects of variables can be interpreted as the pursuit of integration between prior researches that were performed individually.

This study aimed to examine the mediating roles of self-determined motivations on the effect of class climate perceived by middle school students on self-regulated learning ablility. For this purpose, a total of 589 students were selected as subjects in this research. Structural equation modeling was conducted so as to verify the relationship among all the variables. As a results, first, the perceived autonomous class climate had a direct effect on self-regulated learning ability and an indirect effect on self-regulated learning ability through the mediation effect of identified regulation. Second, the perceived controlled class climate had a direct effect on self-regulated learning ability and an indirect effect on self-regulated learning ability through the mediation effect of identified regulation, introjected regulation, and external regulation. This study implies that facilitating autonomous engagement in learning activities will be a effective educational intervention to improve self-regulated learning ability.
