The aim of this study was to examine trajectories in and predictors of marital satisfaction among parents with one year old baby. Latent growth modeling was used with a sample of 984 households. Data from Panel Study on Korean Children conducted by Korea Institute of Child Care and Education were used. The study results revealed that for both fathers and mothers, marital satisfaction decreased over time after the birth of the first child. However, fathers' marital satisfaction decreased more steeply than mothers'. Furthermore, mothers' employment was associated with the changes of fathers' marital satisfaction. Father involvement and marital conflict predicted changes of mothers' marital satisfaction. These findings show that factors such as father involvement and marital conflict are more highly associated with changes in mothers' marital satisfaction than fathers'. Also, the study suggests that parent education should be systematically organized to promote father involvement and to resolve marital conflict.

The object of this study is through an empirical analysis, how cultural capital at the individual level and social welfare expenditure at the national level affect the life satisfaction of the elderly. In this study method, a Hierarchical Linear Model(HLM) analysis was performed on 3,297 elderly people aged 65 and older and 9 OECD countries. As a result of analysis, first, it was confirmed that life satisfaction and social class had a significant effect. Therefore, in to increase the satisfaction of the life of the elderly, policy and practical intervention measures that can narrow the gap between social classes should be prepared. Second, the old-age pension and survivor's pension had no significant effect on life satisfaction. However, as a result of the interaction, social class has a positive effect on life satisfaction, and it was confirmed that the lower the income inequality, the more positive the life satisfaction was. In conclusion, this implies that both individuals and countries should make efforts to variously increase the life satisfaction of the elderly.

The emissions trading system, introduced to reduce greenhouse gas emissions, experienced a sharp increase in emission allowance prices during the second plan period (2018-2020), which led to an increase in the demand for smooth supply and demand of emission allowances, while suppliers anticipating a shortage of emission allowances in the future did not participate in trading. Therefore, the authority temporarily revised the guidelines to ensure that the amount of allowances carried forward is proportional to the trading volume as a market stabilization measure. Through an optimization process using a dynamic nonlinear mathematical model, this paper analyzes the impact of the government's intervention on the carryover policy on GHG emission reductions and emission allowance market prices. According to the simulation analysis results, banking regulations could cause a decline in prices during the regulation period, even though the initial policy was predicted to be adopted.

The present study was to examine the relationship among work-family conflict, anger regulation, and organizational commitment. Four-hundred and eighty-seven workers completed the instruments assessing work-family conflict, anger regulation, and organizational commitment. The results showed that work-family conflict was negatively related to organizational commitment, but not significantly linked to anger regulation, and anger regulation was positively related to organizational commitment. It might be possible to address clearly the relationship among work-family conflict, anger regulation, and organizational commitment, especially the mediation effect of anger regulation, using a large sample.

The objective of the study is to discriminate EEG(electroencephalogram) due to emotional changes. Emotion was evoked by the series of auditory stimuli which were selected from the natural sounds in the sound effect collection of compact disc. Seventeen university students participated and experienced positive or negative emotions by six auditory stimuli with intermission between stimuli. Temporal EEG ($T_3$, $T_4$, $T_5$, and $T_6$) was recorded at the same time and a subjective test was performed on the eleven point scales after the experiment. The maximum and minimum scores of the EEG among six stimuli EEG were analyzed for discrimination of emotion. The EEG signals were transformed into feature objects based on scalar intervention model coefficients. Auditory stimulus was considered as intervention variable. They were classified by Discriminant Analysis for each channel. The features showed results with the best classification accuracy of 91.2 % in $T_4$ for auditory stimuli. This study could be extended to establish an algorithm which quantifies and classifies emotions evoked by auditory stimulus using time-series models.

본 연구에서는 내배수시설 기준 배수구역 경계 재설정 기법을 제안하고자 한다. 내배수시설 경계 재설정 기법이란 경계 재설정에 따른 침수저감 효과를 보다 명확히 나타냄으로써 시스템의 유출량 분산을 통한 침수발생 저감을 목적으로 한다. 기존의 유역 경계 설정이 설계자의 임의성이 개입되어지는 것에 비하여 침수저감 이라는 구체적이고 객관적인 판단 근거에 유역 경계를 설정하는 판단기준을 제공하는 것을 목적으로 한다. 내수침수에 대한 피해 저감을 목표로 하며, 개선된 내배수시스템 구성을 바탕으로 경계 재설정 기법을 실유역에 적용하였다. 경계 재설정을 통한 침수 저감효과 검토는 지리적으로 연속된 인접한 내배수시설 유역을 대상으로 한 기법에 해당하며, 해당 유역간의 효율적인 내배수시설 운영을 포함한 분석을 통해 내수배제 능력을 확보하도록 하는데 의미가 있다. 즉, 빗물펌프장을 이용한 펌프 조기가동 효과를 토대로 침수저감 효과를 검토하고 소화하지 못하는 유출량에 따른 월류발생을 저감하기 위한 경계 재설정 기법에 해당한다. 향후 최적화 기법을 해당 기법에 적용하기 위한 다양한 분석 결과들을 바탕으로 내배수시설 경계 재설정 모형 개발을 위한 사전 검토단계에 해당한다.

Due to the increasing need for 3D spatial data, modeling of topography and artificial structures plays an important role in three-dimensional Urban Analysis. This study suggests a methodology for solving the problem of calculation for the extraction of building boundary, minimizing the user's intervention, and automatically extracting building boundary, using the LIDAR data. The methodology suggested in this study is characterized by combining the merits of the point-based process and the image-based process. The procedures for extracting building boundary are three steps: 1) LIDAR point data are interpolated to extract approximately building region. 2) LIDAR point data are triangulated in each individual building area. 3) Extracted boundary of each building is then simplified in consideration of its area, minimum length of building.The performance of the developed methodology is evaluated using real LIDAR data. Through the experiment, the extracted building boundaries are compared with digital map.

Much of the data used in the analysis of environmental ecological data is being obtained over time. If the number of time points is small, the data will not be given enough information, so repeated measurements or multiple survey points data should be used to perform a comprehensive analysis. The method used for that case is longitudinal data analysis or mixed model analysis. However, if the amount of information is sufficient due to the large number of time points, repetitive data are not needed and these data are analyzed using time series analysis technique. In particular, with a large number of data points in the current situation, when we want to predict how each variable affects each other, or what trends will be expected in the future, we should analyze the data using time series analysis techniques. In this study, we introduce univariate time series analysis, intervention time series model, transfer function model, and multivariate time series model and review research papers studied in Korea. We also introduce an error correction model, which can be used to analyze environmental ecological data.

The purpose of this study was to development a model of the practical skill instruction of the special subject using the problem-based learning in the technical high schools For the study, various literature researches were reviewed intensively about problem solving process, problem -based learning, and learning principals. The process of the practical skill instruction using the problem-based learning was composed with planning, executing, testing and evaluating. In this practical skill instruction using the problem-based learning, the teacher serves as a coach or guide for students' learning. As a facilitator, the teacher challenges, questions, and stimulates the students in their thinking, problem solving and self-directed study. In this process, students represent problem by thinking aloud, assuming responsibility for their own learning, having self-directed study as well as doing cooperative study, and as a result, education changes move from teacher-centered to student-centered.
