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.

The purpose of this study is to conduct a systematic review of the development and implementation of family resilience programs focusing on published papers in domestic Journals, to provide basic data on development of future family resilience programs, and present research directions. For this, I analyzed the contents of 16 published papers in domestic Journals from 2003 to 2016. The analysis was divided into the performance elements of the program and the development factors. The six sub-areas of program execution factors are subjects of study, research design, program duration and time, facilitator, research method, scales and effect analysis. The three sub-areas of the program development factors are the development base, the purpose of the program development, and the main content of the program. Based on the results of this study, it is necessary to develop a family resilience program considering the various problems of each family and the specific environment in the future.

본고에서는 우리나라 전화요금 전략수립에 일조하고자 전화통화의 수요탄력성을 시내통화와 시외통화로 나누어 추정하였다. 먼저 탄력성의 개념과 추정에 관하여 살펴보았으며, 아울러 제외국의 통화수요탄력성을 조사 분석하였다. 추정결과는 제외국에서의 일반적인 경향과 일치하며, 우러나라에서도 전화서비스가 필수품으로 정착되었음을 입증해 주고 있다.

서울과 일산 신도시의 출근통행 교통수단 선택모형을 구축하고, 두 도시간 수단선택행태를 분석.비교하였다. 분석을 위한 자료로는 1996년 서울시에서 수행한 가구통행실태조사자료를 이용하였으며, 수단선택모형으로는 다항로짓모형을 사용하였다. 두 지역 출근통행 수단선택모형의 모형구조상의 차이 및 모형의 지역간 이전가능성을 분석하였고, 출근통행의 시간가치 및 탄력성을 분석하고 비교하였다. 통계적 검증의 결과 출근통행의 수단선택에 있어서, 모형구조적 측면에서나 선택행태적 측면에서 수단 선택모형의 두 도시간 이전은 불가능한 것으로 나타났다. 서울의 출근통행의 시간가치가 일산보다 전반적으로 큰 것으로 분석되었고, 특히 서울의 경우, 택시이용자의 시간가치가 자가용 이용자의 시간가치보다 큰 것으로 나타났다. 두 도시 모두 통행시간에 대한 탄력성 통행비용에 대한 탄력성보다 전반적으로 크며, 버스와 지하철간의 통행시간에 대한 교차탄력성이 매우 높은 것으로 분석되었다.

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.

This study obtained significant results by analyzing 202 dental hygienists in Daegu and Gyeongbuk region with analyzed with descriptive statistics, t-test, ANOVA analysis using the SPSS WIN 18.0 in order to investigate the fusion relationship between anger expression, stress elasticity, job satisfaction, and quality of life of dental hygienists. Anger expressions averaged 1.50, and was high hospital-level, job-motivated, non-self-esteemed, high income, alcohol consumption. Stress resilience was averaged 3.09, and was high when abstinence. Job satisfaction average 3.24, and was high when was pride, abstinence. Quality of life, stress resilience and job satisfaction were positively correlated. Stress resilience and job satisfaction are positively correlated. Overall, information provision and environmental support should be provided to increase job satisfaction and stress resilience in order to improve the quality of life of dental hygienists and reduce the expression of anger.

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 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.

Using methods for the analysis of non-stationary series and error correction models, this study estimates the elasticity of employment with regard to growth rate and its variability. The authors could not find any significant evidence that elasticity has reduced during the last 25 years, which implies that the slow-down of the employment growth did not result from a reduction of the elasticity but from the GDP growth slow-down. Therefore, policy efforts to enhance the capacity of job creation should be made in a manner that can extend the long-term growth potential.
