The purpose of this study is to provide basic data for improving the STEAM class by examining elementary school teachers' difficulties in the STEAM class and discussing solutions. For this research, 25 elementary school teachers in Seoul City and Gyeonggi-do were asked to write their difficulties in the STEAM class in the open-ended questionnaires. After classification of the collected data, an in-depth interview was conducted with one in-service elementary school teacher who is richly experienced in STEAM education to find solutions for each type of difficulties. The study result showed that most of elementary school teachers had difficulties in the STEAM class, due to selection of integrated subjects, production of teaching devices and materials, guidance of group activities, reorganization of the curriculum, assessment and uncooperative co-teachers. One teacher that participated in the interview to discuss solutions for teachers' difficulties was solving the problems in various ways. She said that many of her solutions came from her experience and also, knowledge obtained through a participation in the STEAM training or opportunities to share information with other teachers who belong to the STEAM research institution, was highly helpful.

The purpose of this study is to find out the effect of STEAM program on the scientific communication skills and the learning flow of elementary gifted students. The main findings of this study are as follows: First, STEAM program that mathematical, technical, engineering and art factors were combined based on basic concepts of science were developed. Seconds, the change in the scientific communication skills of experimental group applying STEAM program had statistically meaningful difference (p<.05). Third, the flow of experimental class improved, but it had no meaningful difference statistically (p>.05). But it is expected that continuing level adjusted STEAM program might have positive effect on improving the flow with the following three reasons: 1) The gifted students' flow level on learning before experiment was rather too high to expect short term effect. 2) It was hard for them to achieve flow experience because topic difficulties and students' capacities were not balanced. 3) topic commitments and autotelic behaviors of gifted students were observed during classes. Fourth, by the result of the student satisfaction questionnaire survey on this program, students actively participated in the STEAM program with interest and curiosity. As achieved self-directed problem solving, versatile communication activities and success experiences, their class satisfaction was high. Based on such results, it was expected that the gifted class applied of STEAM program could enhance scientific communication capacity of the elementary gifted students and would further positively influence flow of learning as well. In addition, it was considered to have integrated approach value to elementary gifted and talented education in the aspect that it could satisfy various educational demands of gifted students.

The purpose of this study is to develop a STEAM program using technological pedagogical and content knowledge (TPACK) model to effectively utilize technology to solve the difficulties in the teaching of 'structure and function of our body' unit in the primary science curriculum and to confirm the effect on the academic achievement, creative problem solving ability and scientific interests of elementary students. The program was developed as the STEAM program of the 8th class by utilizing the construction knowledge of the TPACK model. The developed program was applied to 29 experimental group students in 5th grade. And the textbook-oriented circulatory system learning program was applied to 29 5th graders in the same school. As a result of the application of the program, the experimental group showed significant improvement over the comparison group in its creative problem solving ability and scientific interests, and the satisfaction of the class was also high. This caused a positive effect on students because the process of self-directing information about the circulatory system using smart devices, making outputs creatively using 3D printers, and presenting them through role play using produced outputs.

NSSS (Nuclear Steam Supply System) and BOP (Balance of Plant) design works for PGSFR (Prototype Gen-IV Sodium Fast Reactor) have been conducted in Korea. NSSS major components, e.g. reactor vessel, steam generator and secondary sodium main pipes, are designed according to the rule of ASME boiler and pressure vessel code division 5, in which DBA (Design by Analysis) methods are used in the stress assessments. However, there is little discussions about detail rules for BOP piping design. In this paper, the detail methodologies of BOP piping stress assessment are discussed including safety systems and non-safety system pipings. It is confirmed that KEPIC MGE(ASME B31.1) and ASME BPV code division 5 HCB-3600 can be used in stress assessments of non-safety pipes and class B pipes, respectively. However, class A pipe design according to ASME BPV code division 5 HBB-3200 has many difficulties applying to PGSFR BOP design. Finally, future development plan for class A pipe stress assessment method is proposed in this paper.

본 연구는 독서와 공학을 융합한 수업 모델인 노벨 엔지니어링(이하 NE) 교육 프로그램에 관한 것이다. NE 수업의 도구로 VR 저작도구인 CospacesEdu를 이용하여 직접 가상현실을 설계하고 프로그래밍하는 과정을 포함함으로써, 해당 교육 프로그램이 학습자들의 융합인재소양과 학습몰입에 미치는 효과를 확인하였다. 교육 내용의 소재로는 독도 교육을 선정하여 진행하였다. 프로그램의 적용 결과 융합인재소양의 평균이 상승하였으며, 그 중 융합 영역에서 통계적으로 유의미한 변화를 확인하였다. 학습몰입은 총 5가지 하위 영역 중 과제와 능력의 균형 영역에서 유의미한 향상을 보였다. 반면 책 읽기로 시작하여 정보 수집, VR 설계, 이야기 바꿔쓰기까지 진행되는 차시가 긴 NE 수업 모델의 특성상 어려움을 느끼는 학생들이 있었다. 본 연구의 결과가 NE 수업 모델의 일반화에 도움을 주고, 새로운 방향을 제시하는 자료로 유용하게 활용되길 기대한다.

The stay cylinder weld at the steam generator of Korean Standard Nuclear Power Plants is safety class I component and is subjected to be inspected by the volumetric examination such as ultrasonic method. As accessibility of this area is limited due to the narrow space and high radiation, the existing manual inspection method involves various difficulties. Moreover operators may be exposed to internal contamination by contaminated dust during the surface buffing process to improve the inspection reliability of this area. Recently the new automatic inspection system for stay cylinder welds has been developed. The inspection system basically consists of a driving assembly, data acquisition device and signal processing units. The driving assembly is classified by 1) the scanner for inspecting and buffing the weld, 2) pillars for guiding the scanner and 3) the base frame for loading and supporting pillars. The scanner has 4 sensor modules to inspect in 4 refracted angles and 4 incident directions. These components can be inserted into the skirt of the stay cylinder through the manway hole and assembled easily by one-touch in the skirt. Data acquisition device and signal processing units developed in previous works are also newly upgraded for better processing of data analysis and evaluation. The system has been successfully demonstrated not only in the mock-up but also in the field. In this paper, newly developed inspection system for the stay cylinder weld of the steam generator is introduced and their field applications are discussed.
