After Industrial Revolution, new thought system is needed to subdue multi-chanties and complexities of society. Nowadays under 'system theory', these efforts are theorized and organized in fields of science, philosophy and others. From Industrial revolution, before establishing the system theory, system has been needed by the expression methods. From that time, as it could be done, standardization, has been continued. Finally these conclusion reached at the systematic expression methods and when the system was build up, this theory was come true in Art such as De Stijl, Neo-Pasticism, Russian Suprematism and Constructism. For that reason, formal solution to achieve mass reductions was found in Art, so people connected Industry with Art at that time. Systematic expression methods in Art have characteristics of system and reflect mathematics and geometry theory which is based on the system theory. This study analyzes the systematic methods in contemporary interior space through the concept of systematic expression methods in Swiss Allianz's works which used the systematic expression methods and also inquires how the common meaning of system after recent times effect to contemporary design.

In this study, gas flow and temperature distribution in the multi-wafer planetary CVD reactor for the Si epitaxial growth were analyzed. Although the structure of the reactor was simplified as the first step of the study, the three-dimensional analysis was performed taking all these considerations of the revolution of the susceptor and the rotation of satellites into account. From the analyses, a reasonable velocity field and temperature field were obtained. However, it was found that analyses including the upper structure of the reactor were required in order to obtain more realistic temperature results. DCS mole fraction above the satellite surface and the susceptor surface without satellite was compared in order to check the gas species mixing. We found that satellite rotation helped gases to mix in the reactor.

The aerodynamic performance of a cross-flow fan is strongly influenced by the various design factors of a rear-guider and a stabilizer. The purpose of this paper is to investigate the effects of a rear-guider and a stabilizer on the aerodynamic performance of a cross-flow fan. The design factors considered in this paper are a rear-guider clearance, a stabilizer clearance, and a stabilizer setup angle, respectively. This experiment was carried out with a constant revolution number of 700 rpm in a cross-flow fan installed in the fan tester. The static pressure, flowrate, torque, and revolution number were measured in this paper. Also, the pressure coefficient and the efficiency were analysed according to the various assembly conditions using a stabilizer setup angle, a stabilizer clearance, and a rear-guider clearance in the indoor room air-conditioner.

21세기는 4차 산업 혁명을 화두로 다양한 산업분야의 경험과 지식으로 무장한 인재를 필요로 하고 있다. 각 대학은 실무에서 필요로 하는 인재양성을 위한 캡스톤 디자인을 운영하고 있는데 무엇보다 산업체와의 연계를 중요시하고 있다. 그러나 단일전공의 학생들이 팀원을 이루어 기획하기 때문에 현재의 시장상황이나 환경에 대한 인식과 마케팅 및 디자인 부분에는 한계가 있었다. 이에 센터 단위로 진행되는 캡스톤 디자인의 부족한 점을 개선하기 위해서는 기술적인 부분에만 치우치지 않고 공학과 디자인이 서로 협업할 필요성이 있다. 따라서 본 연구에서는 연구자가 공학계열의 미디어소프트웨어 학과에서 운영한 캡스톤 디자인 프로그램의 공학과 디자인 연계 사례를 소개하고 개선방안을 모색한다. 먼저 공학 분야의 캡스톤 디자인의 교육목적과 운영방안에 대하여 고찰하고 연구자가 운영한 프로그램 사례의 결과에 기인하여 개선방안을 제시하였다.

항공기의 추력으로 구동되는 추진축의 회전운동에서 발생되는 진동은 추진축의 수명에 큰 영향을 끼친다. 그리고 회전중 추진축에서 피로파괴가 발생하게 될 시에, 막대한 인명피해를 야기하게 된다. 비행환경에 따라 다양한 회전에 놓이게 되는 추진축에서 떨림이 발생한다. 따라서 이러한 피로파괴가 우려되는 추진축 부위를 본 논문에서는 해석적 연구를 통해 사전에 파악함으로서, 파손방지를 위한 그 내구성이 향상되고 근간된 안전설계를 토대로 융합기술에 접목하여 그 미적인 감각을 나타낼 수 있다.

This study analyzes recent trends in fashion retailing instigated by the fourth industrial revolution and approaches the trends in terms of the convergence of big data and artificial intelligence. The findings are as below. First, companies like 'Edited' and 'Stylumia' offer solutions that support the strategic decisions of fashion brands and fashion retailers by analyzing big data using artificial intelligence. Second, the convergence of big data and artificial intelligence scales personalized service on the web as examples of 'Coded Couture', 'StitchFix', and 'Thread'. Third, the insights gained from artificial intelligence and big data help create new fashion retailing platforms such as 'Botshop' and 'Lyst'. Last, artificial intelligence and big data assist with design. 'Ivyrevel' designs digital fashion, assisted by a macroscopic perspective on fashion trends, market and consumers through the analysis of big data. The Fourth Industrial Revolution brings changes across all industries that will likely accelerate. The fashion industry is also undergoing many changes with advancements in scientific technology. The convergence of big data and artificial intelligence will play a key role in the future of fast-moving industry like fashion, where fickle tastes of consumers are the main drivers.

This research points out the necessity of customized communication education for engineering students in the era of the Fourth Industrial Revolution. This paper also points out such problems of current communication education as presentation and discussion-focused 'Public Speech' exercises, absence of interests about social issues, and lack of interactive communication learning. In general, as the characteristics of their major education, engineering students are not aggressive in self-questioning and active communication rather than their sensitive reaction to the changes of the new era. Considering these characteristics of engineering students, this research emphasizes that future communication education should be deployed from the major-focused thinking to the development of convergent thinking, from the problem-solving to the problem-finding, and from the contentious thinking to the cooperative thinking. In addition, as a class design reflecting future trends, this research emphasizes, firstly the development of cooperative communication education model, secondly active utilization of SMART technology, and lastly the importance of customized-coaching for each student considering their own characteristics and requirements.

The $4^{th}$ industrial revolution has brought innovation in the educational environment. The purpose of this study is to verify the educational effectiveness of smart learning environment especially with the computational thinking. A big data analysis was performed to confirm that computational thinking is the one to prepare the 4th industrial revolution. To teach computational thinking at university, educational design should be careful. This study verified the relationship between improvement of computational thinking ability and major of students with coding education. There was difference in effectiveness of the coding education depending on the major of students, it means students must be guaranteed to be educated by the differentiated coding education for different major. This study extracted factors of computational thinking through literature review. Thirteen research hypotheses were applied for the statistical analysis in R language. It was proved that expectation of class and improvement of abstraction ability and algorithmic thinking ability had mediation effect to the relationship between knowledge acquisition and problem-solving abilities. Based on this study, effectiveness of education can be improved, and it will lead to produce a lot of distinguished students who are ready for the 4th industrial revolution.
