  • This paper estimates output and price elasticities of the industrial water in order to provide the government with tools that help make educated decisions with regard with the water provision policies rendering the latter more efficient. The estimated output elasticity produces useful insights on the role of industrial water as an input into the production process while the estimate of price elasticity enablesus to forecast the effects of various water pricing policies. This paper employs the marginal productivity method in order to estimate the abovementioned elasticities. The magnitude of the estimated output elasticity imply that the value of industrial water is much higher than its average price while the price elasticity estimate suggests that the water pricing policy can be an effective tool of controlling the demand for industrial water.

  • Four hundreds and eighty-seven dental hygiene students were selected and a questionnaire survey was carried out to find out how emotional intelligence and ego resiliency affect interpersonal skills so that this can be the basis to enhance their interpersonal skills. PASW statistics 18.0 was used for analysis, results are as follows: It was statistically significant that students with higher emotional intelligence and ego resiliency and good interpersonal skills answered that they had high economic standard of living (p<0.001, p<0.05). Students raised by parents showed high emotional intelligence and ego resiliency (p<0.05), same result was shown among religious students too (p<0.05). Students with high ego resiliency showed better interpersonal skills (p<0.001), and ego resiliency influenced more on interpersonal skills than emotional intelligence. Therefore, curriculum to develop emotional intelligence and ego resiliency of dental hygiene students to improve their interpersonal skills which is one of the core competences of dental hygienist needs to be planned in the course.

  • 스마트그리드 구현에 실시간요금제 적용이 핵심으로 등장하고 있다. 실시간요금제 적용 시 전력수요의 변동을 시뮬레이션하기 위하여 2005년부터 2009년의 전자식전력량계 계량데이터를 이용하여 전력 수요의 가격탄력성을 구하였다. 가격탄력성을 산출하기 위하여 시계열 분석과 횡단면 분석을 동시에 수행할 수 있는 패널모형 분석을 적용하였으며, 국내 전기요금에 대하여 계약종별, 산업분류별 가격탄력성을 실시간 요금제에 대비하여 1시간 단위로 구하였다. 국내 전력수요의 가격탄력성은 계약종별 및 산업분류별로 대부분의 경우 -0.1 이내로 산출되어 가격탄력성이 매우 낮게 나타났다. 산업분류별로 가격탄력성을 산출함으로써 통계적 유의수준이 높게 나타났다.

  • 생산요소에 대한 수요탄력성은 생산요소 소득의 분배와 생산자의 생산의사 결정에 중요한 영향을 미치게 된다. 본 연구는 생산요소데 대한 수요탄력성을 결정하는 요인을 밝히고 실제 생산요소의 수요탄력성을 측정하여 이를 비교하는데 그 목적을 두고 있다. 이를 위해 규모에 대한 보수 체감의 정도를 달리하여 생산요소 간의 대체성, 생산함수의 기술조건, 생산물에 대한 수요탄력성 정도 및 다른 생산요소의 공급관계 등에 따라 생산요소의 수요탄력성이 어떻게 결정되는가를 이론적으로 분석하고 실제 자료를 이용하여 중요한 농업생산요소에 대한 수요함수를 측정하여 탄력성을 제시하였다. 생산요소에 대한 수요의 탄력성은 위에서 밝힌 이론적 근거 외에도 자료의 이용, 가능성 및 그 종류, 추정방법, 외생변수의 수와 종류 및 수요함수의 모형설정 등의 통계적 요인에 의해서도 결정될 것이다.

  • The purpose of this study is to investigate the effects of the job stress and ego-resilience of kindergarten teachers life satisfaction, and to explore ways to improve life satisfaction. 198 public and private kindergarten teachers and childcare center teachers in Gangwon-do were asked to respond by using job stress, ego-resilience, and life satisfaction questionnaires. Based on the collected data, Pearson's correlation coefficient analysis and hierarchical multiple regression analysis are as follows. First, the higher the job stress of the kindergarten teacher, the lower the life satisfaction, and the higher the ego-resilience, the higher the life satisfaction. In particular, the reward, a sub-variable of job stress, had a significant negative correlation with the kindergarten teacher's ego-resilience and life satisfaction. Second, the predictors of relationship resilience, energy, and reward significantly influenced the life satisfaction of kindergarten teachers, and the relationship resilience was relatively explanatory about life satisfaction. This study suggests that an educational plan to be explored to improve ego-resilience for kindergarten teacher's life satisfaction.

  • The purpose of this study was to examine the relationship among child care teachers' personal characteristics, resilience, and social support. The subjects in this study were 154 child care teachers working in Gangwon province. The resilience questionnaire(Jung Hyun Lee, 2013) revised from KRQT-52(Korean Resilience Quotient Test) and the perceived social support scale(Lee Jae-Young, 2012) were used for this study. For the research analysis, frequency, Cronbach's ${\alpha}$ coefficient, and Pearson's correlation were calculated and ANOVA test, Scheff$\acute{e}$ post-hoc analysis, and regression analysis were conducted. The results are as follows. Firstly, it was revealed that child care teachers' experiences, age, marital status, and type of child care center had a statistically meaningful difference in resilience. In contrast, teachers' educational backgrounds did not have a meaningful difference in resilience. Secondly, all the sub-variables of teacher's perceived social support had a positive statistically significant correlation with all sub-variables of their resilience. Thirdly, physical support of child care teachers' perceived social support had statistically meaningful positive influences on the positive characteristics and the overall resilience. Also evaluative support of child care teachers' perceived social support had statistically meaningful positive influences on the interpersonal skills, self-regulation, positive characteristics, and the overall resilience of resilience. In conclusion, the results indicated that it is needed to strengthen child care teachers' perceived social support for enhancing resilience, taking into account the background characteristics of individual teachers.

  • The purpose of this study was to identify the relationship of the subjective happiness, ego-resilience and academic achievement by type of giver, taker, matcher of nursing students. First, in the result of the type of nursing students, the Taker(43.0%) was the largest, the Matcher (40.1%) was next, the Giver (16.9%) was the least. The mean score of subjective happiness, ego-resilience and academic achievement were 16.9, 94.1, 3.3, respectively. According to the personality type, the Giver reported the highest academic achievement. But the Taker reported the lowest subjective happiness, ego-resilience and academic achievement. There were significantly positive correlations between subjective happiness and ego-resilience(r=.511, p<.001), and ego-resilience and academic achievement (r=.215, p<.05).
