This study aims to investigate the research trend of elementary environmental education. Thus, author keywords were extracted from a total of 197 academic these related to elementary environmental education during two different periods when detailed goals were applied to the 2007 and 2009 revised curriculums respectively, and then this study analyzed the network of author keywords. The results of this study can be summarized as below. Firstly, as a result of analyzing the frequency of author keywords from academic theses related to elementary environmental education, this study discovered 369 author keywords from the period when detailed goals were applied to 2009 revised curriculum. Out of them, it was found that the keyword, 'climate change education', showed the highest frequency, followed by 'environmental literacy' and 'environmental perception', except such central keywords as 'environmental education' and 'elementary school student'. From the period when detailed goals were applied to the 2007 revised curriculum, a total of 394 author keywords were discovered, and the keyword, 'environmental literacy', showed the highest frequency, followed by 'environmental perception' and 'ESD (education for sustainable development)'. Secondly, as a result of analyzing the network of author keywords, this study found out that in the total number of network connections, average connection degree, density and clique, the period when detailed goals were applied to the 2007 revised curriculum was somewhat higher than the period when detailed goals were applied to the 2009 revised curriculum. As a result of analyzing the centrality of author keywords, this study found out that during both the periods, 'environmental perception' and 'environmental literacy' were high in degree centrality and betweenness centrality, except such central keywords as 'environmental education' and 'elementary school student'. As a result of analyzing the components of author keywords as sub-networks, this study discovered 9 components from the period when detailed goals were applied to the 2009 revised curriculum and 6 components from the period when detailed goals were applied to the 2007 revised curriculum. During both the periods, the largest component was composed of keywords high in degree centrality and betweenness centrality.

The objectives of this study were: a) to measure the satisfaction of who volunteered in the activity, and b) to identify factors related to their satisfaction from the activities, and c) to provide policy implications to improve their satisfaction. This study was based on a literature review and empirical analyses. The empirical analyses have been completed through individual interviews with community residents who volunteer the NGO activities in the Korean Federation for Environmental Movement. The major findings from empirical analysis were as follows: As a result of correlation analysis, nine variables affecting the degree of their satisfaction were "activity time", "sex", "support of family and friends", "understanding of environmental NGO activities and fields of environmental NGO activities", "contact points for the activities", "income and vocation". As a result of multiple regression analysis, the five variables affecting the degree of their satisfaction were "understanding of the NGO activities", "income", "support of family", "marital status", "activity period" and these five variables explained 49.1% of the degree of their satisfaction. Based on the empirical findings, the following suggestions could be offered for the environmental NGO activities. 1) Environmental NGOs should offer resident-friendly programs which may help the residents participate in the NGO activities, so the volunteers can participate in the activities with their family, friends, and neighbors. 2) Environmental NGOs should provide appropriate information and educational supports to community residents, which might facilitate them to have a sound understanding of the NGO activities. And the environmental NGOs should provide diverse activity programs to facilitate participation and to formulate eligible management system for the activities. 3) To enhance the satisfaction of participation, environmental action programs should be organized and conducted through a careful consideration of the status of the community, the characteristics of residents, and so on. To provide better contact points, environmental NGOs should cooperate with religious organizations in communities, social groups, media and so on.

To control non-point source pollution at a watershed scale, rainfall-runoff characteristics from forest watersheds should be investigated since the forest is the dominant land use in Korea. Long-term monitoring would be an ideal method. However, computer models have been utilized due to limitations in cost and labor in performing long-term monitoring at the watersheds. In this study, the Geo-spatial interface to the Water Erosion Prediction Project (GeoWEPP) model was evaluated for its runoff prediction from a coniferous forest dominant watersheds. The $R^2$ and the NSE for calibrated result comparisons were 0.77 and 0.63, validated result comparisons were 0.92, 0.89, respectively. These comparisons indicated that the GeoWEPP model can be used in evaluating rainfall-runoff characteristics. To estimate runoff changes from a coniferous forest watershed with various cover degree scenarios, ten cover degree scenarios (10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%) were run using the calibrated GeoWEPP model. It was found that runoff increases with decrease in cover degree. Runoff volume was the highest ($206,218.66m^3$) at 10% cover degree, whereas the lowest ($134,074.58m^3$) at 100% cover degree due to changes in evapotranspiration under various cover degrees at the forest. As shown in this study, GeoWEPP model could be efficiently used to investigate runoff characteristics from the coniferous forest watershed and effects of various cover degree scenarios on runoff generation.

The purpose of this study is to analyze the effective factors that influence subjective cognition, conflict degree of work-family balance, and cognition of family strength according to general characteristic factors, working environmental factors, and home environmental factors, as well as analyze the relationships among subjective cognition, conflict degree, and cognition of family strength. The main data source for analysis in this study is the Second National Survey of Korean Families by the Ministry of Gender Equality and Family in 2010. The survey includes the analysis of 419 respondents who have a dual income and live with their wife. The collected data are analyzed using SPSS 19.0. The results of the study are as follows. First, subjective cognition of work-family balance is influenced by satisfaction of work, division of housework, and care of family. Second, the conflict degree of work-family balance is influenced by age, working week, and satisfaction with work. Third, the relationship between subjective cognition and conflict degree of work-family balance is a negative correlation. The relationship between subjective cognition of work-family balance and cognition of family strength is a positive correlation but the difference between conflict degree of work-family balance and cognition of family strength is not significant. Finally, for the married men, the working environmental factor is a significant factor for the work-family balance. And the higher the satisfaction of work and division of domestic work, the greater is the balance between work and family. This suggests that they also have a higher cognition of family strength.

The on-line cure monitoring during the cure process of composite materials is important for better quality and productivity. The dielectric sensor for cure monitoring consists of base film and electrodes. Because the characteristic of dielectric sensor for the on-line cure monitoring is dependent on the base material, width and number of electrode, etc, the dielectric sensor should be standardized. And the selection of base film material of sensor is very important. In order to prevent the measuring errors generated from the increase of environmental temperature, the base film material should have stable dielectric constant with respect to environmental temperature. In this study, the newly developed dielectric sensor for cure monitoring was designed and the dissipation factor which is function of degree of cure was measured using the sensor. The relationship between the dissipation factor and degree of cure with respect to environmental temperature was investigated.

This study attempted to explore the characteristics of conflicts in marriage life, and to analyze their impacts on global marital satisfaction perceived by wives in rural areas. The survey data was gathered from 151 rural wives. The degrees of three types of conflicts were shown to be low. while in terms of the degree of seriousness, environmental, interpersonal and intrapersonal are in descending order. Especially the degree of the environmental types of conflicts were significantly different across the family life cycle. In order to analyze the relationships between the types of conflicts and the marital satisfaction, logistic regression were performed. It was found that the environmental type of conflict was negatively associated with the likelihood of satisfaction in the marriage life. On the other hand, one of the control variables, the degree of satisfaction on the husband's job, i.e., farming, was positively associated with it.
