In Korea, the methods of estimating groundwater recharge can categorized into two groups. One is baseflow separation method by means of groundurater recession curve, the other is water level fluctuation method by using the data from groundwater monitoring wells. Baseflow separation method is based on annual recharge and lumped concept, and water-table fluctuation method is largely dependent on monitoring wells rather than water budget in watershed. However, groundwater recharge rate shows the spatial-temporal variability due to climatic condition, land use and hydrogeological heterogeneity, these methods have various limits to deal with these characteristics. For this purpose, the method of estimating daily recharge rate with spatial variability based on distributed rainfall-runoff model is suggested in this study. Instead of representative recharge rate of large watershed, the subdivided recharge rate with heterogeneous characteristics can be computed in daily base. The estimated daily recharge rate is an advanced quantity reflecting the heterogeneity of hydrogeology, climatic condition, land use as well as physical behaviour of water in soil layers. Therefore, the newly suggested method could be expected to enhance existing methods.

The purpose of this study is to ascertain the effect of both educational satisfaction and relational support on the self-efficacy of secondary school students and then eventually on their entrepreneurship. Testing self-efficacy as a mediator is another aim of this study. The findings indicated that both educational satisfaction and relational support have positive relationships with the self-efficacy of students. Self-efficacy also had a positive impact on entrepreneurship. The core part of this study focuses on the role of both educational satisfaction and relational support in fostering the self-efficacy and entrepreneurship of secondary school students. These results can serve as practical guidance when making decisions regarding the adequate pedagogy for secondary school students in order to promote entrepreneurship among the adolescents.

Changes in the amount, intensity, frequency, and type of precipitation, in conjunction with global warming and climate change, critically impact groundwater recharge and associated groundwater level fluctuations. Monthly gravity levels by the Gravity Recovery and Climate Experiment (GRACE) are acquired to monitor total water storage changes at regional and global scales. However, there are inherent difficulties in quantitatively relating the GRACE observations to groundwater level data due to the difficulties in spatially representing groundwater levels. Here three local interpolation methods (kriging, inverse distance weighted, and natural neighbor) were implemented to estimate the areal distribution of groundwater recharge changes in South Korea during the 2002-2016 period. The interpolated monthly groundwater recharge changes are compared with the GRACE-derived groundwater storage changes. There is a weak decrease in the groundwater recharge changes over time in both the GRACE observations and groundwater measurements, with the rate of groundwater recharge change exhibiting mean and median values of -0.01 and -0.02 cm/month, respectively.

This study is aimed at investigating floodgate characteristics and environmental issues in Gwangjucheon and examining possible problems of expanding river maintenance water being carried on in the context of river recovery works. In general, the obtained results show the following. The treatment water provisioned in the restoration project of the drying stream going through the water circulation device can pollute the land and groundwater in the Gwangjucheon Basin. Besides, although about $17,565m^3$/day of water is available in the upper ground, most of it go to the junction and exhausting directly to the waste water treatment or going into the groundwater. Because of the drying stream, the amount of water going to the ground is increased. Therefore, efficient land use along with regulations to protect cultivated land and ensure recovery works of city stream through the recovery of water circulation by constructing and expanding a special drainage system are of vital importance.

The processes and rates of groundwater recharge were studied by long-term monitoring of groundwater level and isotopic compositions of precipitation, surface water and groundwater in the Yeosu area. The isotopic compositions of surface water and groundwater were directly related to the precipitation event. It is also shown that the minimum amount of precipitation for infiltration to groundwater is about 20mm. The isotopic variations of groundwater shows that the Isotopic composition of groundwater changed by each precipitation event between June and Sep. 2000 is gradually changed without input of precipitation again. It indicates that the groundwater recharged from the upper part is mixed with the groundwater in reservoir. The infiltration rate of first precipitation event after a dry season is estimated to be 16.5% using isotopic mixing equations. It is expected that the groundwater recharge rate could be estimated more quantitavely, if the isotopic method is combined with the conservative methods.

The aim of this paper is to suggest some ways of moral education for the building of children's social awareness and relationship skills as social and emotional competencies. Based on the social and emotional learning(SEL), this paper is tried to provide the effective ways to develop children's social awareness and relationship skill. According to SEL, social and emotional competence is the ability to understand, manage, and express the social and emotional aspects of one's life in ways that enable the successful management of life tasks such as learning, forming relationships, solving everyday problems, and adapting to the complex demands of growth and development. And it is also the process of acquiring and effectively applying the knowledge, attitudes, and skills necessary to recognize and manage emotions. Five key competencies such as self-awareness, social awareness, responsible decision making, self-management, relationship skills are taught, practiced, and reinforced through SEL programming. Moral education and social and emotional learning have emerged as two prominent formal approaches used schools to provide guidance for students' behavior. social awareness and relationship skills are necessary for succeeding in school, in the family, in the community, in life in general. Equipped with such skills, attitudes and beliefs, young children are more likely to make healty, caring, ethical, and responsible decisions and to avoid engaging in behaviors with negative consequences such as interpersonal violence and bullying.

In the creative problem solving processes, the core was to generate unique and various ideas. Thus, an assumption reversal thinking skill needed to be considered as a concrete method that could help students who have difficulties with generating ideas. In this study, we applied the assumption reversal thinking skill to university students and explored the characteristics of the idea generation process. On the basis of the results, we found that the assumption reversal thinking skill helped students generate new ideas, inducing their perspective changes. Therefore, we could ascertain the possibilities of the assumption reversal thinking skill as a thinking frame supporting students' idea generation. However, there is a need to develop methods for students to exclude prejudice by theoretical judgment, intervention of the value, and experience for fostering more effective assumption reversal thinking. Also, ways should be considered so that students would be able to cultivate task commitment and courage of implementing new ideas, bearing criticism from others.

The purpose of this paper is to show the role of aesthetic experience from appreciating the creative products in the creative economy. The paper has found that the universality of creativity is a very basic foundation of the creative economy and anyone can enhance his or her creativity from appreciating or consuming the creative products and apply such acquired creativity to the non-creative industries. From these findings we can derive two public policy implications. The first one is that the government should support people to pursue a diverse and unique experience, i.e. aesthetic experience with creative products. And the second one is that art education both inside and outside of the school curriculum should be emphasized.
