Ultra High Performance Cementitious Composites with compressive strength 200MPa (UHPCC-200) is proposed for the structural design of super high hybrid wind turbine tower to gain durability, ductility and high strength design objectives. The minimal wall thickness is analyzed using basic bending and compression theory and is modified by a toque influence coefficient. Two cases of wall thickness combination of middle and bottom segment including varied ratio and constant ratio are considered within typical wall thickness dimension. Using nonlinear finite element analysis, the effects of wall thickness combinations with varied and constant ratio and prestress on the structural stress and lateral displacement are calculated and analyzed. The design limitation of the segmental wall thickness combinations is recommended.

KEPCO International Nuclear Graduate School (KINGS) is dedicated to nurturing leadership-level professionals in nuclear power plant (NPP) engineering. KINGS have designed curriculum based on two philosophies. First, we balance aspects of discipline engineering, specialty engineering, and management engineering in the framework of systems engineering. Second, KINGS have designed the curriculum so that students can learn and experience the know-what, know-how and know-why level knowledge of NPP engineering and management. The specialization programs are opened during the 2nd year for 3 trimesters and those are a process of learning through practical project courses. The objectives of the specialization programs are to help students to learn the NPP life cycle technologies in highly structured and systematic ways. The systems engineer program (SEP) is one of the specialization programs. A practical case of the SEP which was applied to the project course for the NPP electric power system design education will be elaborated in this paper.

Objectives: The objectives of this study are to introduce the development process of work situations and types in the revised regulations on wearing personal protective equipment (PPE) for hazardous chemical handlers, analyze the implementation of the regulations, and then provide basic data for future education strategies. Methods: The development process of work situations for regulation was explained through a flowchart by year. In 2018, a survey of 30 chemical managers and 201 managers and handlers was conducted based on recognition of work situations and the related regulations. In 2019, 91 chemical managers and 204 handlers were surveyed to find the degree of compliance with regulations, direction for improvement of understanding the regulations, and training methods. Results: Only 78.0% of chemical managers and 66.7% of handlers said they were aware of the regulations (p<0.05). Just 79.0% of handlers knowing the regulations said they would wear PPE in compliance with these regulations. Therefore, the best way to make workers wear proper PPE in accordance with regulations is to strengthen the promotion of education on regulations. In order to improve the quality of education, 51.7% of managers and 33.3% of handlers cited educational content (video, ppt, etc.) as the top priority. Conclusion: This study suggested that more educational opportunities should be provided and educational content should be developed in order for workers handling hazardous chemicals to wear PPE as prescribed in regulations.

본 논문은 성균관대학교에서 개설되고 있는 "과학기술 문서 작성 및 발표" 강좌의 특징과 핵심 교육목표에 중점을 두고 학생들에게 부과되는 과제를 중심으로 공학적 의사소통, 공학적인 문제들을 인식하며 이를 공식화하여 해결하는 일종의 사고능력과 표현능력을 동시에 훈련하는 기초과정의 측면에 기반 하였다. 과학기술 문서 작성 및 발표수업은 기본적으로 Blended Learning 학습유형중 문제 중심학습(PBL)에 기반을 두어 학생들 스스로의 문제해결력을 키워갈 것을 강조하며 자기 주도적으로 학습할 수 있는 능력을 키워주는데 지향점을 두었다. 팀별활동을 통해 학습자들이 좀 더 구체적인 문제를 이끌어내도록 참여를 장려하였고, 학생들 스스로 주제를 설정하는 능동적인 과정 속에서 자신의 활동을 객관화시켜 검토해 보는데 수업의 목표를 두었다.

There is currently a growing need to nurture creative and convergent talent in the face of the fourth Industrial Revolution. Developing such talent requires interdisciplinary convergent education across the science, engineering, humanities, social studies, and arts disciplines. Such interdisciplinary convergence could cultivate humanities and social knowledge and qualities along with scientific expertise. In Korea, there are currently six science schools for the gifted that aim to discover and nurture science, technology, engineering, and mathematics (STEM) researchers from an early stage, and two science and art schools for the gifted that aim to cultivate new talent combining students' scientific and artistic qualities. These schools establish and follow curriculums that are suited to achieving the education objectives guaranteed by the Gifted Education Promotion Act and its Enforcement Decrees. This study compares the curriculums and curriculum tables of the science schools for the gifted to those of the science and art schools for the gifted to evaluate their methods of operation and performance. Additionally, it determines which curriculums provide an opportunity for students to nurture convergent thinking, and discusses how suitable curriculums could be implemented to develop convergent thinking.

산업체 수요에 기반한 공학혁신형 산업의료원 교과목과 운영 사례에 대해서 소개한다. 산업의료원 교과목은 산업체에서 제공한 애로기술 문제를 교수와 학생이 산업의료원 교과목 수업을 통해서 해결한다. 산업체는 애로기술을 제시하고 담당교수는 제시된 애로기술을 해결하는 강의 계획을 수립해서 학생들과 함께 산업체 애로기술을 해결하는 과정을 수행하고 학생들은 그것을 통해서 현장적응력을 키웠다. 학생들은 교과목 운영 목적 인식 정도, 수행기간의 적절성, 커뮤니케이션의 원활성, 전공지식의 이해 및 활용에 기여, 문제해결능력, 협업 학습 능력, 진로선택의 기회, 교과목 추천 등에 높은 평가를 하였다. 산업의료원은 한 학기 과정보다는 두 학기로 운영한 경우가 학생들의 만족도가 높게 평가된다. 그 이유는 산업의료원에서 제시하는 애로기술 문제가 한 학기에 해결책을 찾기 어렵기 때문이다. 산업의료원 교과목을 통해서 산업체에 취업연계를 가질 수 있는 기회가 될 수 있다.

The purpose of this study was to develop and present the accreditation criteria for engineering technology education programs in junior colleges. Research methods used in this study were review of related literature, experts discussion, and Delphi technique. Especially, Delphi technique was the major research method of this study. The Delphi surveys were taken for about seven weeks and three rounds at a higher level of expert participation. Major results of the study were as follows: 1. It proved that thirty six of total forty items had the content validity as the accreditation criteria of engineering technology education programs for junior colleges. CVR(Content Validity Ratio) of four items were below .33 and eliminated four items from the final accreditation criteria. 2. It proved that total Cronbach ${\alpha}$ was very high .9142 and reliability was very high all over items. It proved that six items made worse reliability, therefore it was desirable to exclude six items for increase of reliability. But the final accreditation criteria included six items, because they had a high validity as well as increasing rate of Cronbach ${\alpha}$ was very low with the exception of them. 3. Items of high importance were drawn out through analysis of importance. It proved that thirty of total forty items were more than 4.00 average in importance and ten items were less than average. 4. In conclusion, the final accreditation criteria were developed and presented through such analysis of validity, reliability and importance. The final accreditation criteria for engineering technology education programs in junior colleges were composed of seven domains of educational objectives, learning outcomes, curriculum, staff, facilities, institutional support, and student assessment.
