In this paper, we propose an AR system which enables monitoring and managing of the operation process of the construction site. In case of the conventional construction managing system, a worker takes several images of the construction site and sends them directly to the supervisory headquarter, which manages the progress of the construction process and checks weather the construction is achieved according to the architectural design or not. Due to the nature of the offline process, the conventional management system has time and monetary constraints, and there exists a disadvantage that it is impossible to make quick decision-making and real-time communication with the work site. In order to minimize these disadvantages, we proposes an AR real-time construction monitoring/management system. In particular, we aim to developed a system based on mobile device so that it can maximize usability. The efficiency of the proposed system is verified through several experiments and implementation results.

This study examined effects of the communication accompanied with music therapy on the anxiety of patients during a MRI examination. In the experiment group consisting of thirty patients and the control group consisting of thirty patients, the experiment was performed from February 1st 2014 to March 31st 2014 in hospital C located in Daegu Korea. The research design was a non-equivalent control group quasi-experimental study. The results showed that the anxiety score (VAS score) on communication with music therapy of the experimental group was significantly lower (p=.001), than that of the control group. Among the vital signs, the blood pressure was similar in both groups. On the other hand, the pulse rate of the experiment group was significantly lower (p=.001). Four categories of the physical discomfort (perspiration, facial change, change in physical posture, and change in vocal sound) did not show any statistically significant difference between the control and experiment group. Among the mental discomforts, dizziness did not have a significant difference between the experiment group and the control group, but the experimental group had significantly low fear (p=.001) and anxiety (p=.001). From the above results, communication accompanying music therapy proves is an effective alternative examination method that reduces the anxiety of patients.

The purpose of this study is to acquire teaching insights for improving scientific literacy by analyzing the effects of scientific communication skills, science process skills, and logical thinking skills of elementary school students on academic achievement level. The participants are 64, sixth grade elementary school students. Survey materials include the results of Scientific Communication Skill Test (SCST), Test of Science Process Skills (TSPS), Group Assessment of Logical Thinking (GALT), multiple choice test & short answer test, descriptive answer test on science, and academic achievement level test on all subjects. Based on these data, the study analyzed the relationships of science process skills, logical thinking skills, and scientific communication skills, and each category's effect on academic achievement level. Furthermore, under the assumption that scientific communication skills are affected by science process skills and logical thinking skills and directly influence the academic level, the research discovered three types of correlations as a structural model. The results show that there are considerable correlations in scientific communication skills, science process skills, and logical thinking skills. Also, these three abilities have meaningful correlations with learner's writing and descriptive question level on science curriculum and overall academic achievement level; the level of correlation differ a bit by subcategory factors. In conclusion, setting the model, science process skills and logical thinking skills influence scientific communication skill, and the skill directly influences the learner's academic level. Further analysis of the results show that scientific communication skill influences the academic achievement level of all subjects the most.

The purpose of this study was to investigate the influence of maternal post-natal depression on children's communication competence, maternal self-efficacy and parenting style. The data on 1,438 pairs of children and their mothers were provided by The Korean Children Panel Study (KCPS). Mothers were assessed by K6(Kessler et al., 2002), The Pearlin Self Efficacy Scale(Pearlin et al., 1981), and The Parental Style Questionnaire(Bornstein, et al., 1996). Children's communication competence was assessed by K-ASQ. The collected data were analyzed with t-test and path analysis. The major results of this study were as follows : (1) Post-natal maternal depression was not directly associated with the children's communication competence. (2) Post-natal maternal depression indirectly influenced the children's communication competence via maternal self-efficacy and the parenting style. The results of this study suggest that post-natal depression within 1 year will not have an effect on the children's communication competence directly, but will indirectly influence it through maternal self-efficacy and the parenting style when the children are 2 years old.

Globally SW education is becoming increasingly important, and the government is preparing for this trend as a mandatory implementation of SW education in the 2015 revised curriculum. However, because the 17 hours of annual education offered in the course of Practical Arts cannot have great educational effects, this study attempted to develop a robot-based SW education program related to other regular subjects. Also in order to verify the effects of the program related to future competencies, problem solving ability and communication ability were selected as key factors. The paired t-test was conducted to examine whether there was a significant difference between pretest and posttest results. As a result, it was verified that the subject-related SW education program using robots was effective in improving students' problem-solving ability and communication ability. In addition, after the program was completed a survey was conducted, and it was possible to confirm that students could have positive perception on SW education.
