Objectives Although the word Zheng (證) is widely used basic term in nowaday's East Asian traditional medicine, it's definition can't be found in ancient texts before 20th century, and the history in which that term got general meaning in public, have not been clearly introduced. So the present author show the way Zheng confirm it's modern implication. Methods To search the books that contain any contents on Zheng's definition, the author mainly used the electronic texts of Super Star Reader (超星閱讀器). To search modern study article on Zheng's definition, the author used China National Knowledge Infrastructure (www.cnki.net). Results The present study shows that : although Treatments according to disease Pattern Identification (辨證施治) have been prominent treatment modality in East Asian traditional medicine, the general definition of disease Pattern (證) was given in late 20th century. Especially from 1955 to 1965, some major scholars like Ren Ying Qiu (任應秋), Zhu Yan (朱顔), Qin Bo Wei (秦伯未) and Jiang Jian Fu (蔣見復) did important roles in it's concept creation. Conclusions Modern concept of Zheng (證) was defined in late 20th century.

The purpose of this study are to analyze how well middle and high school students understand the concept definition of quadrangle and to explore the phenomenon about their concept image. A test tool was developed and 60 8th graders, 63 9^th graders and 65 10^th graders were tested, and some students who needed in-depth analysis were interviewed. The results are as follows. First, it cannot be said that understanding level of the concept definition of the quadrangle naturally improves as the grade level goes up. Particularly, it was found that the understanding of the definition of the rhombus is the lowest in all three grades compared to other quadrangle. Second, although female students understood the definition of square better than male students, the understanding level of the definition of trapezoid, parallelogram, rhombus, and rectangle did not differ by gender. Third, it was found that the students who did not understand the concept definition of the quadrangle were more and more influenced by the concept image as the grade level went up. Fourth, it showed that a tendency to be less influenced by the concept definition and more influenced by textbooks and teachers as the grades go up when students form a concept image.

Since the term, 'scientific literacy' was introduced by P. D. Hurd in 1958, it has been used as a term, representing major goals in science education. In Korea, the term 'scientific literacy' was used in the statement of the summative objective of the 2007 science reformed curriculum. But in various educational contexts m which teachers and researchers works, the definition of the term has not been used consistently. This phenomena would be interpreted as showing limits of the term describing the goals of science education. This study examined the historical change in the meaning of the term in purpose of trying to anchor the definition. In this study, the changing period was divided into before introducing the term and after. The after era was divided into the period of confusing and anchoring in the meaning, and the period of expanding the meaning. Especially, after science as intellectual ability was conceptualized in science education communities, the meaning of scientific literacy was partially confused. In current time, as the concepts of language in cognitive science influenced the use of language in science education, the trends of expending the meaning of scientific literacy has been grasped in science education community.

In this paper, we first analysis definition of continuity of functions in high school textbooks, the mathematics high school curriculum and university mathematics textbooks. We surveyed what was causing the students to struggle in their concept image of continuity of functions. We arrived at that students' concept for errors in images of continuity of function were caused by definition of continuity of functions in high school textbooks.

The standard definition of an instantaneous temporal part cannot properly deal with cases involving time travel. This paper provides a new definition of an instantaneous temporal part by appealing to David Lewis's distinction between external time and personal time. The new definition avoids the problems because it does not allow more than one instantaneous temporal part of an object at each moment of its personal time. We argue that this new definition, combined with our new perdurantist semantic thesis, deals with cases of time travel successfully.

The definition of cake is not established for cake filtration, and especially the definition was impossible for the filtration of the floc already sedimented. The definition is proposed with the experimental method named 'filtration-permeation'. The limit of water content which can be achieved with cake filtration of floc was established with the definition of cake. The expression operation of which the purpose is to reduce the water content of pre-formed filter cake is calculated with our 'unified theory on solid-liquid separation' and compared with the experimental results. The importance of expression is analyzed by the calculated whole procedure of cake filtration and expression. The method determining the most effective operational conditions of filter press including the cake discharge and washing time is proposed.

지금까지 영상 콘텐츠 제작 기술의 발전은 SD(Standard Definition)에서 시작하여 HD(High Definition)와 FHD(Full High Definition)를 거쳐, UHD(Ultra High Definition)에 이르기까지 화질을 중심으로 이루어져 왔다. UHD 에 이르며 육안으로는 그 이상의 해상도로 제작된 콘텐츠와 구분하는 것이 힘들어졌으며, 이에 영상 콘텐츠 제작은 화질이 아닌 제한된 촬영 장비들로부터 촬영 방법, 영상 화각의 개선 작업 등으로 그 방향을 전환하고 있다. 이의 연장선 상에서 360 도 영상에 대한 기술개발이 활발히 이루어 지고 있다. 방송 분야에서는 360 도 영상의 실시간 스트리밍 적용 가능성이 모색되고 있는데, 이것이 가능 하려면 대량의 동영상 데이터를 실시간으로 스티칭하여 전달하는 기술이 필요하다. 따라서 고속 이미지 스티칭이 가능해질 경우 실시간 동영상 스티칭을 통해 방송 통신 분야에서의 서비스 향상에 기여할 것으로 보인다. 본 논문은 이미지의 edge 정보를 방향성을 가진 데이터로 분할하여 특징점을 추출하고, 이후 가중치를 통한 특징점 매칭으로 기존의 이미지 스티칭 방법 보다 빠른 속도의 알고리즘을 제안한다.

Risk management at an early stage of projects is known as an effective method expected various benefits. The PDRI(Project Definition Rating Index) by the CII(Construction Industry Institute) is defined project scope for reducing risks. In addition, the PDRI is one of the verified methods for achieving benefits by a risk management. The literature review in Korea about risk management is all about focusing on construction works and the construction phase. Thus, we need to extend the perspective of a project management such as the PDRI. To develop the Korean PDRI, However, we have to consider Korean situations. Therefore, in this study, we analyze some previous studies of PDRI' indexes and its using methods, and suggest the new direction for using PDRI in Korea. This method will enable to improve the scoring method of a project management with PDRI in Korea.
