Unsafe working environments slow down working speed in that it takes a lot of time to respond in case of an accident, greatly reducing the productivity of construction work. Therefore, proper safety management that does not impede the productivity of construction works is a very important factor for successful construction project. However especially in mega project, the mutual effects of safety management and productivity are complex. Therefore, this study establishes a causal model between safety management and productivity influencing factors based on effectiveness metrics, and analyzes the effect of increased site congestion due to excessive personnel input, irregular safety measures and inefficient change of work schedules. The result of this study, is expected to contribute to enhancing the competitiveness of the construction industry as the basis for establishing a safety management plan that can secure appropriate productivity.

In this study, a problem-centered learning based STEAM field experience learning program was developed and the effects of applying it were investigated. The program was composed of 8 sessions by using problem-centered learning education method and integrating STEAM elements between disciplines. The contents of program are as follow. In the step of sharing problems and making a problem-solving plan, they understood the various examples and meanings of endangered species, explored the project activities, and made an inquiry plan. In the search and re-exploration phase, a smart device was used to investigate the appearance, habitat environment and cause of extinction for Clithon retropictus, and a site inquiry plan was established for each group. Then, they moved to the field to explore brackish-headed gallops and discuss ways to protect endangered species. In the step of creating a solution, a web-based report was produced as the final product using smart devices based on the results of the inquiry. In the presentation and evaluation stage, the produced web-based report was used to present each group, conduct mutual evaluation, and organize project activities. The developed program was applied to 6th grade 29 students enrolled in the J University Gifted Education Center. In order to find out the effectiveness of the program, tests of science process skill, creative problem-solving ability, and scientific attitude were conducted before and after of program learning, and the results were statistically analyzed by t-test. In addition, a STEAM program satisfaction test was conducted after project in order to find out the satisfaction of the class. As a result of application of the program, the results were significantly improved in openness, criticism, and creativity among the sub-factors of creative problem-solving ability and scientific attitude. Satisfaction with the STEAM program was also high, but no significant result was found in science process skill.

In light that solidarity movements become significant under the situation of 'labor and labor movement' crisis, our study pays attention to the fact that the Hope Bus campaigns made remarkable achievements, and aims to figure out how those campaigns were successful, by focusing on their solidarity networking. The successful operating conditions of solidarity networking in the Hope Bus campaigns are examined in three aspects - the conditions of triggering, forming, and activating. The solidarity networking of Hope Bus campaigns were mainly triggered by the injustice of layoffs by Hanjin Heavy Industry, aerial protest by Jin-sook Kim, and the tragic symbol of the protest site (Crane no. 85). The solidarity movement of Hope Bus could be formed by the mutual trust and cohesive team-building of key network brokers, their utilization and expansion of social movement networks, and massive ripple effect of SNS-mediated communication. The solidarity networking of Hope Bus was effectively activated by open and de-hierarchical operations of the central planning group, active solidarity activities of participant groups, and the provision of 'heuristic experience' for developing the sensibility to labor solidarity. The virtuous combination of those three operating conditions leads to the building of unified forces among social movements, massive civil participation, and meaningful movement outcomes, through the solidarity networking of Hope Bus campaigns.

The research is to analyze current situation of the coordinated development of "5 Region" and "4 Road" in Henan Province and put forward problems about the coordinated development of the "5 Region" and "4 Road" with the inland geographical location in China by drawing on the experience of the coordinated development of related industries in developed countries and regions based on China's "One Belt And One Road". According to the problems, a plan for the promotion of opening up to the outside world is provided. Through research, the following problems are found: First, the superposition advantage of five districts' and "four roads' has not been fully brought into play. Second, the collaborative linkage mechanism is not sound. Third, modern comprehensive transportation hub facilities are not fully completed. Fourth, the industrial support capacity is insufficient. Fifth, basic support is difficult to meet the needs of future development. The plan is as follows: First, building a top-level strategic platform and improve the policy support system. Second, we need to enhance the advantages of the four Silk Roads and accelerate their interconnected development. Third, establishing a coordination and mutual assistance mechanism to stimulate the superposition effect of industrial clusters. The significance of this study is that it can be used as research data to predict the future direction of China's "One Belt and One Road" policy and enlightenment to stimulate the economic revitalization of inland provinces.

In this paper, parameter characteristics such as pH effect, isotherm, kinetic and thermodynamic parameters and competitive adsorption of dyes including malachite green (MG), direct red 81 (DR 81) and thioflavin S (TS), which have different functional groups, being adsorbed onto activated carbon were investigated. Langmuir, Freundlich and Temkin isotherm models were employed to find the adsorption mechanism. Effectiveness of adsorption treatment of three dyes by activated carbon were confirmed by the Langmuir dimensionless separation factor. The mechanism was found to be a physical adsorption which can be verified through the adsorption heat calculated by Temkin equation. The adsorption kinetics followed the pseudo second order and the rate limiting step was intra-particle diffusion. The positive enthalpy and entropy changes showed an endothermic reaction and increased disorder via adsorption at the S-L interface, respectively. For each dye molecule, negative Gibbs free energy increased with the temperature, which means that the process is spontaneous. In the binary component system, it was found that the same functional groups of the dye could interfere with the mutual adsorption, and different functional groups did not significantly affect the adsorption. In the ternary component system, the adsorption for MG lowered a bit, likely to be disturbed by the other dyes meanwhile DR 81 and TS were to be positively affected by the presence of MG, thus resulting in much higher adsorption.

This study aims to examine the mutual influences of negative parenting attitudes, self-esteem, and life satisfaction perceived by adolescent children through longitudinal perspective. Data from the first to third years of the panel of the first year middle school students were used among the 2018 data of the Korean Children and Youth Panel Survey (KCYPS) of the Korea Youth Policy Institute. The longitudinal correlation was analyzed by applying the autoregressive cross-lagged model which can determine the direction of longitudinal causality between variables. As a result of the analysis, it was found that the negative parenting attitudes, self-esteem, and life satisfaction perceived by adolescents had a positive effect on the negative parenting attitude perception, self-esteem, and life satisfaction at later times, respectively. In addition, the higher the negative parenting attitude at the previous point was, the lower the self-esteem or life satisfaction afterward. The higher the life satisfaction, the lower the negative parenting attitude of the parents, and the higher the self-esteem. Recognition of negative parenting attitudes of parents lowered the self-esteem of adolescents, whereas the cross-delay coefficient from self-esteem to negative parenting attitude perception was not significant. Through these results, the longitudinal relationship between negative parenting attitude perception of adolescence, self-esteem, and life satisfaction was confirmed and efforts to form positive self-esteem and improve life satisfaction were discussed.
