Research and development on flexible electronic displays has gone on for over 20 years. Despite this history, very few flexible displays have entered the marketplace. I will discuss the history of development of flexible display technology and the technical and market forces that have slowed the commercialization of this technology.

In this paper, I will investigate the cultural factors that determine the direction of development of early mathematics. And I will survey the philosophical background of Greek logical mathematics. Then, I will survey the distinctive features of Korean.Chinese ancient mathematics which hindered the development of mathematics.

This paper deals with the origin of the concept of lattices in mathematics and its development until 1930's. Although it is purely mathematical, its formation is due to the development of symbolic logic Further, logicians were mostly concerned about how to imitate the methods and duplicate the problems of algebra but not the application to mathematics. The first purely mathematical approach was given by Dedekind and his results were neglected and then reappeared in 1930's.

Since The Korean Reliability Society had been founded in 1999, development history of reliability engineering in Korea is reviewed and research outputs and papers from 2008 to current are analyzed in terms of types of industry, product life cycle, hardware vs software, and theory vs application. The purpose of this research is to review the recent reliability engineering research conducted in Korea including development history as well as published papers to identify the weakness and/or deficiencies in order to suggest the future research directions, which would contribute the development of industries in Korea.

The general efforts of applied research and development can be divided into product development, process development, process design, process equipment design, and operation The fed batch culture as one effort of theprocess development in fermentation industry has been practiced since the early times of human history. One particular industrial application with long history is in the cultivation of the baker's yeast where the glucose effect at relatively high glucose concentration is the general rule.

This study is on the theory of Piaget's reflective abstraction and the mechanism of the development of knowledge and the history of algebra and its application to understand the difficulties that many students have in learning algebra. Piaget considers the development of knowledge as a linear process. The stages in the construction of different forms of knowledge are sequential and each stage begins with reorganization. The reorganization consists of the projection onto a higher level from the lower level and the reflection which reconstructs and reorganizes within a lager system that is transferred by profection. Piaget shows that the mechanisms mediating transitions from one historical period to the next are analogous to those mediating the transition from one psychogenetic stage to the next and characterizes the mechanism as the intra, inter, trans sequence. The historical development of algebra is characterized by three periods, which are intra inter, transoperational. The analysis of the history of algebra by the mechanism explains why the difficulties that students have in learning algebra occur and shows that the roles of teachers are important to help students to overcome the difficulties.

The objective of this article is to analysis of Acupuncture & Moxibustion Fix-a-day Method (AMFDM) shown in the acupuncture documents of the Chosun-Korea dynasty. Through such inquisition, The development process of AMFDM could be found. cross-comparison analysis of the contents of three medical books, Chim-Gu-Tek-Il-Pien-Zip(CGTIPZ), Dong-Eui-Bo-Gam(DEBG) and Chim-Gu-Gyung-Hum-Bang (CGGHB) of the Chosun-Korea dynasty. The development process of AMFDM of the three books is different from each other, depending on the purpose of writing books. But The three books contain common parts. It could be divided into three types, Simple-AMFDM, Extensive-AMFDM and Spirit-Existence-AMFDM. The development process of AMFDM of the Chosun-Korea dynasty has three steps. First, Integration and specialization phase in CGTIPZ. CGTIPZ sum many kind of AMFDMs up, and compare them to be specialized area. Second, Setting theory phase in DEBG. DEBG theorize AMFDM made of Spirit-Existence-AMFDM. Third, Practical use phase in CGGHB. CGGHB invented practical reinforcement to replace complicated ones.

The 19th CPC National Congress has a key historical significance in the development of China's constitution. It will also play a decisive role in the history of the seventy years'constitutional change in New China. XiJinping's new socialist thought with Chinese characteristics established in the report of 19th CPC National Congress will be written in the preface of the March 2018 National People's Congress's constitutional amendment. The fifth revision of 1982 Constitution will touch on many issues such as the leadership of the CPC into the constitution, the abolition of the tenure of the president, the constitutional oath system, and the reform of the national supervisory system. In addition, the constitutionality review system, the establishment of the National Security Council, the constitutional status of socialist public property and private property and the adjustment of major economic system has become a hot topic in the theory field. In the history node towards a socialist country ruled by law, the theory and practice of the China indeed have the academic ideas, value position and path model differences, which will delay the Chinese constitutional development, but also is the necessary pain in the process of moving towards the rule of law in China. Indeed, how to the development and where to go in the future of Chinese constitutionalism itself has sample value, which deserves rational attention and in-depth inquiry from Chinese and Western academics.

본 연구는 중학교 이차방정식 단원에서 조선시대(朝鮮時代) 수학사(數學史)를 효과적으로 활용하기 위해 먼저, 수학교육에서 수학사의 활용과 중학교 수학 교과서에서 다루고 있는 수 학사의 유형 및 그 내용을 살펴보고, 조선시대의 수학자인 경선징(慶善徵), 홍정하 (洪正夏), 이상혁(李尙赫) 등이 제시하는 이차방정식의 구성과 해법에 대해 조사하여 중학교 수학에서 활용할 수 있는 방법에 대해 알아보았다. 이와 같은 조선시대 수학사는 이차방정식에 대한 이해를 높이고 풀이에 대한 흥미와 동기를 유지시키기 위한 자료, 활용 단계에서 개념적 사고와 반성적 사고를 고취시키기 위한 자료로 활용할 수 있다.
