The capabilities of a high-resolution Digital Image Correlation (DIC) system are presented within the context of deformation measurements of full-scale concrete columns tested under reversed cyclic loading. The system was developed to have very high-resolution such that material strains on the order of the cracking stain of concrete could be measured on the surface of full-scale structural members. The high-resolution DIC system allows the measurement of a wide range of deformations and strains that could only be inferred or assumed previously. The DIC system is able to resolve the full profiles of member curvatures, rotations, plasticity spread, shear deformations, and bar-slip induced rotations. The system allows for automatic and objective measurement of crack widths and other damage indices that are indicative of cumulated damage and required repair time and cost. DIC damage measures contrast prevailing proxy damage indices based on member force-deformation data and subjective damage measures obtained using visual inspection. Data derived from high-resolution DIC systems is shown to be of great use in advancing the state of behavioral knowledge, calibrating behavioral and analytical models, and improving simulation accuracy.

The purpose of the study is to determine the poverty and distributional effects of the implementation of Tax Reform for Acceleration and Inclusion Law. The Computable General Equilibrium-Top Down Behavioral Microsimulation was used to obtain the effects of the tax reform on macroeconomic and microeconomic levels. Moreover, the Poverty Gap Index, Squared Poverty Gap Index, Foster, Greer, and Thorbecke Measures of Poverty, and Sen-Shorrocks-Thon Index were used to measure the poverty effect of the tax reform. Meanwhile, the Gini Coefficient and SST Gini Coefficient Index were used to measure the distributional effect of the tax reform. The results show that the implementation of the tax reform has resulted in a significant increase in household income and disposable income. Region IV has the highest estimated increase in household income. Meanwhile, Region IV remained to have the lowest household income. Further, the findings of this study suggest that the tax reform resulted in a significant decrease in the magnitude of poor and the number of poor in the Philippines. However, the result of the study also suggests that the effect of tax reform manifests no differences in terms of the poverty gap measured through the Foster, Greer, and Thorbecke poverty index due.

Objectives: Executive dysfunctions including working memory deficit have been suggested to be one of the major neuropsychological etiologies of attention-deficit hyperactivity disorder (ADHD). The purpose of this study was to investigate the augmentative effects of working memory training on the behavioral problems, quality of life, and parental stress of medicated children with ADHD. Methods: Twenty-five children with ADHD, aged 9 to 19 years, who were being treated with ADHD medication, were included. The participants were trained with a commercially available and computerized working memory program ($Cogmed^{(R)}$) for 5 weeks without any alteration of their medication. The Child Behavior Checklist (CBCL), KIDSCREEN-52 quality of life measure, and Parenting Stress Index-Short Form (PSI-SF) were administered before training, and 4 weeks and 7 months after training, respectively. Results: After completing the training, the anxiety/depression, social problems, thought problems, attention problems, aggressive behavior, and externalizing problems scores in the CBCL were significantly reduced. The score on the Parent-child dysfunctional interaction in the PSI-SF was also decreased. However, the scores related to the quality of life were not changed. These changes were still observed 7 months after the training. Conclusion: Cogmed working memory training can be a promising training option for the additional improvement of behavioral problems and parental stress in medicated children with ADHD.

In this research, a habitat model for Chinemys reevesii is suggested based on the components and variables of the Habitat Suitability Index which was determined through a series of literature researches, site surveys, and behavioral analysis. After reviewing the general habitat requirements, the site surveys(9 reservoirs) from July to December 2010, and the behavioral analysis of five Chinemys reevesii, the relationship between the behavioral and habitat use pattern was evaluated. According to the site surveys and behavioral analysis, the ecological core area(FK 50%) was about 0.96ha on average, the influence area(FK 90%) 4.22ha, and the home range was about $37.75{\pm}17.26m$ on average. As for the habitat use pattern of Chinemys reevesii, it travels through canals, and is influenced by the surrounding land uses. Also when there is a lack of food, the home range increases, and during hibernation, Chinemys reevesii prefers to be in an area within 1~2m range of water shores of fine textured soil and aquatic plants. After analyzing the information, the HSI standard was set and its components were determined as food, sunbathing and cover, aquatic environment, and spatial relationships. And the variables and the ranges of the components was determined as aquatic plant cover(0~49.81%), sandy area($3{\sim}13m^2$) and water velocity(0~60cm/s) etc. Lastly, plans and sections of the habitat model is provided designed according to the information from the researches, and problems to consider during habitat restoration was suggested in order to help understand about Chinemys reevesii habitat.

Concidering environmental education as an ultimate resolution for environmental problems, we conducted a study focusing on affective matters. An instrument was developed to evaluate attitudes of elementary and middle school students toward environmental problems. To develop a reliable Likert-type evaluation instrument scale with which emotional intensity could be judged, mean, standard deviation, response frequency distribution, discrimination index, reliability were calculated. As a result, 21 statements for recognition level and 14 statements for behavioral level were made(The Cronbach alpha coefficient of the instrument was .786). This instrument was used to evaluate 5th and 6th grade elementary school students and 1st and 2nd grade middle school students(total number of subjects was 980). The result of this survey can be summarized as follows. 1. Students recognized the seriousness of environmental problems but they did not behave in such a manner as to prevent it. 2. As a result of t-test, behavioral level score of elemenatary school students was significantly higher than that of middle school students(p<.001). 3. This study showed that there was a significant correlation between the recognition level score and the behavioral level score(r=.386, p<.001). 4. Two-Way ANOVA was used to analyze that there was any significant difference according to grade and sex. The results were as follows. (1) No significant difference was found in total score. (2) On recognition level, female students' score was signigicantly higher than that of male students(p<.01). (3) On behavioral level, higher-grade students' score was lower than that of lower-grade-students (p<.001).

Purpose: The purpose of this paper is to examine the effect of the VKOSPI index on short-term stock returns after a large-scale stock price shock of individual stocks of firms in the distribution industry in Korea. Research design, data, and methodology: This study investigates the effect of the change of the VKOSPI index or investor mood on abnormal returns after the event date from January 2004 to July 2022. The significance of the abnormal return, which is obtained by subtracting the rate of return estimated by the market model from the rate of actual return on each trading day after the event date, is determined based on T-test and multifactor regression analysis. Results: In Korea's distribution industry, the simultaneous occurrence of a bad investor mood and a large stock price decline, leads to stock price reversals. Conversely, the simultaneous occurrence of a good investor mood and a large-scale stock price rise leads to stock price drifts. We found that the VKOSPI index has strong explanatory power for these reversals and drifts even after considering both company-specific and event-specific factors. Conclusions: In Korea's distribution industry-related stock market, investors show an asymmetrical behavioral characteristic of overreacting to negative moods and underreacting to positive moods.
