With the introduction of the 2015 revised curriculum, software education became mandatory in elementary school. The practical subject in the content for the software education consists of information ethics, algorithms, programming, and computer science. Especially, elementary school encourages the unplugged activities. Unplugged activities are preferred among the teachers in the education field as a teaching-learning method. However, those teachers pointed out that the lack of suitable unplugged activity materials was the biggest challenge. In addition, it was pointed out that the existing materials were not suitable for achievement standards, and there are many simple playing-oriented educations that are not linked to computing activities. In this study, we developed an unplugged activity-oriented robot that can be used for the elementary students to learn the basic control structure suggested in the achievement criteria SW education and to develop creative problem solving ability through various activities using sensors. The effectiveness was verified through the software class using the developed robot in this study.

Computational thinking has been recently highlighted as an essential ability of the 21st Century so that many educational efforts have focused on broadening participation in computing and promoting computational thinking in K-12 settings. This paper describes the impact of creative learning activities with the Scratch on middle school students' computational thinking and creative potential. The learning activities were designed and implemented in 12 sessions with 34 middle school students. The pre and post creative potential assessment results show that students' creative personality and ideational behavior were significantly enhanced. Also, project portfolio analysis shows that students came to understand several computational concepts that are useful in a wide range of programming contexts: sequences, loops, conditionals, events, and operators.

The infinite layer compound $ACuO_2$, (A-Alkaline earth) consists of infinite stacking of $CuO_2$ planes separated only by alkaline earth ions. This compound attracted much attention because it contains only key ingredient of all cuprate high temperature superconductor; $CuO_2$ plane with controllable carrier concentration without charge reservoir block. High pressure synthesis method has been found to be preferable for this system due to its ability of doping various lanthanide ion into A site with larger superconducting volume fraction. But rigorous study on this rudimentary compound has been hindered by insufficient quality of sample. Especially superconductlng volume fraction was often too small to identify its origin. In this presentation, we report high pressure synthesis of $Sr_{0.9}Ln_{0.1}CuO_2$ (Ln=La, Sm). By controlling the heating temperature precisely during high pressure synthesis we could have superconductors with quite high superconducting volume fraction for this compound. The magnetic properties of the graln aligned samples show very different behavior compared to the cuprate high temperature superconductors. Details will be discussed.

Polyethylene glycol (PEG) has been the most commonly used polymer for the past few decades in the field of biomedical applications due to its gold standard stealth effect. PEGylation of antibody-drug conjugates, liposomes, peptides, nanoparticles, and proteins is done to improve their pharmaceutical efficacy and pharmacokinetic properties. PEGylation of antibodies with various PEG linkers improves targeting ability by increasing the blood circulation time and thus enhances the biodistribution profiles. It also assists in minimizing the immediate capture by the reticuloendothelial system. In this review, we summarize the effect of PEG linkers in an antibody conjugation and their pharmacokinetics in the field of biomedical imaging.

This study proposes to find out what effects physical effort using props has on infants' ability in relation to their creative physical expression and physical self-concept. This study targets three-year-old preschoolers who attend S and T nursery, located in Yeonje, Busan, of which 16 belong to an experimental group. The research tools used in the study are the creative physical expression test by Kim Eun-Shim(1994), which is the modified version of Bae Hyun-Suck's testing tool(1990), and an altered version of the questionnaire focusing on physical self-concept by Whang Sun-Gack(2001). The experimental group is divided into a large and small sub-group and then physical activities involving props are done by these divided experimental groups once or twice a week for 12 weeks, while outdoor activities are carried out with the comparison group once or twice a week for 12 weeks. For both groups, a total of 20 experiments are done. To obtain answers to the research questions, an individual version of the T-test is conducted using means and standard variations of the experimental and comparison groups. The results of this study are as follows : 1) the physical efforts of the experimental group using props reaped more positive effects as regards creative physical expression than the comparison group, 2) the positive effect on the participants' physical self-concept is also more evident in the case of the experimental group.

Creativity is always important in science gifted education. There are many research results about enhancing the creativity. One of the ways of enhancing students scientific' creativity is to let them think and research like scientists so that they can follow how scientists find problems and solve them. So in this study, scientific creative elements were extracted from the Pauling's detailed examples of research process by using many documents. Abductive reasoning, paradox, changing the perspective, modeling, simplifying, converging thinking, diverging thinking, and metaphorical thinking are thinking methods that were extracted from the Pauling's research process. Repeated experiment, co-experiment, using both theories and experiments, and social obligation as a scientist are research methods. Scientific creative elements that were extracted suggest some direction that have more scientific creativity, more ability to find problems, and more ability to form theories in science education or in science gifted education.
