This article aimed to explore the optimization of mineral admixtures and retarding admixture for high-performance concrete. In essence, fresh concrete can be regarded as a mixture in which both coarse and fine aggregates are suspended in a cement-based matrix paste. Based on this view, the test procedure was divided into three progressive stages of binder paste, mortar, and concrete to explore their rheological behavior and mechanical properties respectively. At each stage, there were four experimental control factors, and each factor had three levels. In order to reduce the workload of the experiment, the Taguchi method with an L9(3⁴) orthogonal array and four controllable three-level factors was adopted. The test results show that the use of the Taguchi method effectively optimized the composition of high-performance concrete. The slump of the prepared concrete was above 18 cm, and the slump flow was above 50 cm, indicating that it had good workability. On the other hand, the 28-day compressive strength of the hardened concretes was between 31.3-59.8 MPa. Furthermore, the analysis of variance (ANOVA) results showed that the most significant factor affecting the initial setting time of the fresh concretes was the retarder dosage, and its contribution percentage was 62.66%. On the other hand, the ANOVA results show that the most significant factor affecting the 28-day compressive strength of the hardened concretes was the water to binder ratio, and its contribution percentage was 79.05%.

This study was conducted to improve the stability of cut slopes of forest roads in granitic weathered soil areas. The study area is a national forest road (road length 28.48 km) in Pyeongchang-gun, Gangwon-do. After data collection, a statistical analysis was performed using IBM SPSS (Ver. 26.0). First, the correlation analysis showed that structure, slope position, soil erosion, slope, and aspect (N, S) were correlated with vegetation coverage (p < 0.05). Elapsed years, slope distance, and aspect (E, W) were found to have no correlation with vegetation coverage. (p > 0.05) Second, one-way ANOVA and Kruskal-Wallis test results showed that vegetation coverage was worse when the slope was located at the top or the middle of the slope than at the bottom of the slope. In addition, the site with sheathing and gabions showed good vegetation coverage when compared with the site without structures. In the case of soil erosion, areas with severe damage and moderate damage showed worse vegetation coverage. Therefore, it is necessary to strengthen the slope angle of the cut soil of the granitic weathered soil area from 1 : 0.5 - 1.2 to 1 : 0.8 - 1.5. In addition, structures such as sheathing and gabions should be installed on granitic weathered land.

The purpose of this study was to investigate (1) children's field dependence by age and sex, (2) children's interpersonal problem solving ability by age, sex, and contextual factors, (3) children's interpersonal problem solving ability by field dependence. The subjects were 120 five-, seven-, and nine-year-olds. Children's field-dependence was measured with the Children's Embedded Figures Test (CEFT). Children's interpersonal problem solving ability was measured with the Preschool Interpersonal Problem Solving Test (PIPS Test). Statistical methods adopted for data analysis were frequencies, percentiles, means, standard deviation, t-test, oneway ANOVA. $Scheff{\acute{e}}$ test and Pearson's correlations. Major findings were that (1) The older children were more field-independent than the younger ones (2) The older children suggested more problem solving methods and higher-level problem solving strategies than the younger ones. (3) Children suggested higher-level problem solving strategies in contexts involving familiar as opposed to unfamiliar participants and contexts involving children as opposed to adults. (4) 9-year-olds' field-independence was positively associated with interpersonal problem solving ability.

The aim of this study was to identify the utilization of health services and factors influencing the quality of life(QOL) of migrant workers. The participants were 135 migrant workers in Korea. Data was collected from September 10th 2012 to November 15th 2012. The data was analyzed using descriptive statistics, t-test, ANOVA, Scheff' test, and hierarchical multiple regression. Immigrant workers experienced difficulty in using health services and had a $14.25{\pm}2.01$ QOL, which was relatively low. The factors influencing QOL were the length of stay in Korea, residence areas, and satisfaction with health services. Final regression model accounted for 16.7% of the variance in QOL. The satisfaction level with health services was the most influential factors in the level of the QOL. Therefore, diverse strategies should be developed to enhance the satisfaction with health services in Korea migrant workers.
