대학 태권도전공자의 중국 국가이미지가 중국진출을 위한 진로준비행동 및 취업의도에 미치는 영향
陳肖依(Chen Xiaoyi) 한국무예학회 2015 무예연구 Vol.9 No.1
본 연구는 대학 태권도전공자들의 중국 국가이미지에 대한 인식과 평가가 어느 정도 이고 이들의 중국 국가이미지가 중국진출을 위한 진로준비활동과 해외취업의도에 어떠한 영향을 끼치고 있는지 알아보는데 연구의 목적이 있다. 이러한 목적을 달성하기 위 해 2014년에 걸쳐 K 대학교 태권도 전공자를 대상으로 182명의 자료를 실제 분석하였다. 분석결과 첫째, 중국 국가이미지 중 경제이미지요인, 정치이미지요인과 문화이미지 요인은 진로준비행동에 유의미한 영향관계를 가지고 있는 것으로 나타났다. 둘째, 중국 국가이미지의 하위요인인 정치이미지요인은 해외취업의도에 유의한 영향을 미치는 것으로 나타났다. 셋째, 진로준비행동의 하위요인들 중 실천적 노력요인, 정보수집활동요인은 해외취업의도요인에 긍정적인 영향을 미치고 있음을 나타내 준다. This study focuses on how university students major in Taekwondo evaluate and recognize China’s images and how that images affect their career preperation and intention of overseas employment. To accomplish this study, In 2014 the researcher surveyed 182 K University student major in Taekwondo. The results are the followings; firstly, the China's image in economy, politics and culture have positive influences on the career preparation. Secondly, China's image in politics has a positive influence on the intention of overseas employment. Thirdly, among the sub-factors of career preparation, practical effort factors and information gathering activities have positive influences on the intention of overseas employment.

3D concrete printing technology builds structural components layer-by-layer with concrete extruded through a nozzle without using forms. This technology can simplify construction processes by optimizing design flexibility, construction time, and cost. Furthermore, the 3D printing technology is easy to make an irregularly shaped and function embedded building(or object) which is difficult to be constructed by conventional construction method. However, the 3D printing concrete is not suitable for current commercial standard and the material itself. It is also difficult to apply it to the construction site due to the lack of initial strength and the nozzle which is clogged during the process. The research of mix proportion design process for 3D printing concrete which differs from the conventional concrete is necessary in order to solve the problems. This paper aims to calculate the 3D printing concrete mix proportion design process based on the mix materials and performance information derived from the previous researches. Therefore, the usage variation range, mutual influence relationship, and the importance priority of the mix proportion are analyzed. Based on this results, the basic design process of 3D printing concrete which contains planning design phase, basic design phase and validating performance phase is suggested. We anticipate to confirm applicability verification about the actual production by referring to this 3D printing concrete mix proportion study. In the future, this study can be utilized for blueprint of the 3D printing concrete mix proportion.

공압 프레스용 CTE 스프링 브레이크 시스템 성능에 대한 연구
김수태(S. T. Kim),진초(C. Chen),주경진(G. J. Ju),이정규(J. G. Lee) 유공압건설기계학회 2017 유공압건설기계학회 학술대회논문집 Vol.2017 No.5
A study on the pneumatic spring brake system for pneumatic press machine is carried out. In the modern industrial manufacture, high accuracy, super-speed, high automation and high security are demanded on the press machine. The quick rhythm and high-frequency of supplying materials of the punch press machine makes operators suffer from tiredness both spiritual and physical, which leads to having hands and head wounded or disabled.. As a result, it is necessary and urgent to design and install a qualified brake system and safety equipment to protect operators in the press machine. In this study, the performance of the CTE braking system is mainly analyzed and experimented. Analytical and experimental results show that the brake system with DH40 * 70 of the brake spring have satisfied the conditions of braking time 0.06s and angle 84 degree. The obtained results can be applied to the design and the improvement of brake system.
