Groundwater monitoring data from the National Groundwater Monitoring Stations, a total of 320 stations, were analyzed to identify the response of water level and quality to the Odaesan earthquake (M4.9) occurred in January 2007. Among the total of eight stations responded to the earthquake, five wells showed water-level decline, and in three wells, water level rose. In terms of recovery, water levels in four stations had recovered to the original level in five days, but not in the rest four wells. The magnitude of water-level change shows weak relations to the distance between the earthquake epicenter and the groundwater monitoring station. However, the relations to the transmissivities of monitored aquifer in the station with the groundwater change were not significant. To implement the earthquake monitoring system through the groundwater monitoring network, we still need to accumulate the long-term monitoring data and geostatistically analyze those with hydrogeological and tectonic factors.

Objectives: The purpose of this study was to investigate the current status of parents' monitoring of school lunch programs and to examine the relationship of parents' school lunch monitoring with their level of trust in school lunch programs. Methods: During November 2016, a web survey was conducted with 1,283 parents who had participated in monitoring of school lunch programs. A total of 621 parents completed the questionnaires (48.4% response rate) and the responses from 442 parents were analyzed (34.5% analysis rate) for elementary (n=196) and middle/high school parents (n=246), respectively. Results: Both the elementary and middle/high school parents most wanted to participate in monitoring 1~2 times per month, which was less frequent than their current practice. They showed the highest experience rate in 'food sanitation' area in both the prior training and actual practice of school lunch monitoring. They most responded 'increasing trust in school lunch programs' as a merit and 'lack of parents participating in monitoring' as a problem of school lunch monitoring. The average levels of trust did not differ between elementary and middle/high school parents. Multiple regression analyses showed that elementary school parents' level of satisfaction in the monitored school lunch programs was positively associated with the parents' level of trust in general school lunch programs. Monitoring frequency and parents' age, in addition to level of satisfaction in the monitored school lunch program, were associated with level of trust in general school lunch programs among middle/high school parents. Conclusions: There was room for change in parents' school lunch monitoring programs to meet parents' needs better. Well-managed school lunch monitoring programs contributing to parents' satisfaction with school lunch programs could increase parents' level of trust in school lunch programs.

The purpose of this study was to examine the effects of adolescents' school adjustment on depression in their transitional period and to find the moderating effects of parental support, parental monitoring, and peer support on the relationship between school adjustment and depression. The participants were 550 first graders in three middle schools in Incheon Metropolitan City and Kyung-gi Province. The major findings of this study were as follows: First, adolescents' school adjustment had significant effects on depression. The lower the level of school adjustment was, the higher the level of depression was. Second, parental support, parental monitoring, and peer support had moderating effects on the relationship between school adjustment and depression. Parental support decreased the depression of adolescents who were at a lower level of adjustment to peer relationship or school class. Parental monitoring decreased the depression of adolescents who were at a lower level of adjustment to school adjustment. On the contrary, parental monitoring increased the depression of adolescents who were at a higher level of adjustment to school adjustment. Peer support decreased the depression of adolescents who were at a lower level of adjustment to school class.

In the Republic of Korea, Ministry of Construction & Transportation and Korea Water Resources Corporation manage the national groundwater monitoring network at the 169 stations and will organize the supplementary groundwater monitoring network at the 10,000 stations by 2011 year. The method that organizes the monitoring network was developed using the Analytic Hierarchy Process with pairwise comparison. Several estimation factors for the estimating every district were selected to reflect each district conditions. Their weighting value was decided by pairwise comparison and questions to the experts about groundwater The optimal number of groundwater monitoring well was calculated through the developed method. To verify this method, groundwater was monitored in Jeonju city by way showing the example. The study area In Jeonju city needs 7 stations for the supplementary groundwater monitoring network. The results monitored in 7 stations inferred the groundwater level around the study area by Kriging. The mean of residual between inferred groundwater level value from Kriging and actual groundwater level is rather low. Furthermore, the mean and standard deviation of residual between inferred groundwater level change and actual groundwater change is much lower. The Fact that 7 monitoring stations are sufficient for observing the groundwater condition in the study area makes it possible for suggested monitoring number to be proper.

In these days, as it frequently happens that water level in the river exceeds the design floods due to irregular heavy rainfall, so it is required, first of an, to manage with railroad bridge safely. Because train control criterion under heavy rainfall is still not prepared and automatic flood monitoring system for railroad bridges is not used, worry over invisible economic loss due to train passage delay is in existence. Therefore, it is important to secure the safety and detect the risk like turnover or failure of railroad bridges through systematic disaster prevention system. And the transition from conventional monitoring method to real time monitoring method supported by sensors and communication system with high technology is rapidly needed. This research is on developing the real time flood monitoring system which prevents railroad disasters in advance by detecting continuously the water level of railroad bridge through CCD camera and water level gauge.

The purpose of this study was to examine: (1) whether the level of parental monitoring changes during adolescence; (2) if it changes, what is the pattern of the change; and (3) whether the effects of adolescents' attachment to their parents on parental monitoring are dependent on time. Six waves of data from the Korea Youth Panel Study (KYPS) were used to address the research questions. The participants of the KYPS were 3,449 (1,725 boys and 1,724 girls) adolescents who participated in the study once a year for 6 years (from the 2nd grade in middle school until their high school graduation). Latent growth modeling (LGM) was used to analyze the data. The findings are as follows: the level of parental monitoring significantly increased over the six waves of the study, and the adolescents' attachment to their parents was a time-dependent predictor of parental monitoring. The results indicate that the quality of adolescents' attachment to their parents is an important factor that makes a difference in the level of parental monitoring by, possibly, affecting the level of adolescents' disclosure to their parents.
