본 연구는 수학적 연결성 구현에 대한 초등 교사들의 인식과 실태를 살펴보고자 지역별 학교 수에 비례하여 층화 군집 표집을 실시하여 28개 학교, 567명의 교사들의 설문지를 분석하였다. 그 결과 수업에서 구현할 수학적 연결성으로 사회적 연결성에 비해 지적 연결성에 대한 인식이 높았으며, 지적 연결성 하위 내용 중에는 실생활과의 연결에 대한 인식이 높았고 실제 수업에서도 가장 많이 구현한다고 응답하였다. 연결의 방법으로는 다양한 연결을 사용하였으나 추론, 학생들의 활동 결과 반영 등의 방법에 활용도가 낮았고 지원을 필요로 하는 자원으로는 실제 수업 사례에 대한 요구가 많았다. 이러한 교사들의 인식을 바탕으로 수업에서 수학적 연결성을 구현하는 방안에 대한 시사점을 제공하고자 한다.

Recently, as the height of building is getting higher, the applications of CFST column for high-rise buildings have been increased. In structural system of high-rise building, The RC core and exterior concrete-filled tubular (CFST) column-beam pinned connection is one of the structural systems that support lateral load. If this structural system is used, due to the minimal CFST column thickness compared to that of the CFST column width, the local moment occurred by the eccentric distance between the column flange surface from shear bolts joints degrades the shear strength of the CFST column-beam pinned connections. This study performed a finite element analysis to investigate the shear strength under eccentric moment of the CFST column-beam pinned connections. The column's width and thickness were used as variables for the analysis. To guarantee the reliability of the finite element analysis, an actual-size specimens were fabricated and tested. The yield line theory was used to formulate an shear strength formula for the CFT column-beam pinned connection. the shear strength formula was suggested through comparison on the results of FEM analysis, test and yield lime theory, the shear strength formula was suggested.

For the last several decades, it has been recognized that technology is a key factor in becoming an ADC and an advanced firm. So many countries and individual firms have been increasing investments on technology development. Especially LDCs including Korea choose technology transfer and transaction as an important alternative of their own technology development. To activate technology transaction and transfer, it is necessary to establish an technology transaction system, namely a Technomart that will make good connections between technology suppliers and technology buyers, and efficient functional linkages of supporting infrastructures including organizations and laws related with technology transactions. Therefore this study reviewed both the characteristics of technology transfer and transaction and a conceptual structure of a Technomart through a literature review. And then, the study analyzed the Technomart related laws including an intellectual property right, a copyright, a patent right, and electric transaction related laws. In conclusion the study proposed the development directions of the Technomart related laws.

The international government committee is progressing their agreements about intellectual property protection of traditional knowledge(TK), gene resource(GR), folklore(FL) in WIPO. It is in the course of selection with precedence of TK, GR, FL in WIPO, focused on discussions about listing of TK documents, standardization of DB construction, sharing and profit distribution of GR. We made some plans to deal with agreements in WIPO. These plans consist of 5 subjects which are investigation about intellectual property related laws and systems, study of examination and finding, construction of DB information, development of value evaluation system, development of industrialization system with TK, GR, We suggest preceding details about 5 subjects respectively. It is the character of this plan that patent information DB system of TK, GR is the axis. It is the most important thing in these plans to succeed that we have to have connections with expert groups in order parts and government officials, taking whole supports of government because our traditional medical related study basis is weak.

The purpose of this study was to improve the practice of performance assessment in elementary science education and to support it according to the levels teachers' concerns. So this study was conducted by applying CBAM which is based on teachers' concern, which was designed for the investigation of the elementary science teachers' concern, their performance level, intellectual understanding, status of performance. and stage oi awareness and the connections between these factors. The study involved 311 elementary school teachers in the city of Seoul. The result of this study was as follows: First, the stage of teachers’ concerns performance assessment in science marked 49.5％, indicating that about half of the teachers was staying on the informative stage which could be generally occurring in the beginning of performance the curriculum innovation. The level of performance marked 33.8%, which was regarded as the stage of elaboration. For the category of intellectual understanding, most of the teachers didn’t fully understood the performance assessment. Regarding the status performance, 90.4％ of the teachers were implementing the assessment at the state of knowing the purpose of it. However. 40.5% of the teachers didn't fully understand the specific characteristics of the assessment. Also, the results of analyzing the teachers’ awareness on science performance assessment indicated that they have slightly positive positions. Secondly, the result of analyzing the stages of concerns for the assessment, based on the elementary school teachers' personal background, levels of implementation, and their intellectual understanding showed that the concerns were significantly different with the categories of their workplaces(p<.05). Finally, the result of analyzing the relationship among the concerns for the science performance assessment, levels of implementation and intellectual understanding indicated that there were significant differences in levels of implementation with the degree of intellectual understanding (p<.001).

Tabriz under Mongol Ilkhanate rule commanded a global reach in the thirteenth-century Afro-Eurasian world. Tabriz functioned during this period not only as a commercial emporium and diplomatic center but as a seat of innovative artistic and intellectual activity. Consideration of Tabriz as a world historical city offers insight into the economic and social dynamics that shaped a critical passage in Eurasia's history including regions of the Mediterranean and East Asian zones.

본 연구는 한 학기 동안의 3학년 수학 수업에서 해당 교실의 사회적 구조를 형성하는 과정을 분석하고 그 속에서 교사와 학생, 학생과 학생 간의 다양한 사회적 상호작용 및 관계를 바탕으로 학습이 이루어지는 과정을 탐색하였다. 탐색 결과, 학기 초반에는 전반적인 사회적 규범의 형성과 함께 생산적인 수학 학습을 위한 여러 가지 기본적인 사회적 구조를 형성하는 데 초점을 두었다. 학기 중반에는 수학 개념에 대한 이해에 중점을 둔 탐구가 나타났으며 학생들의 상호작용에서도 모르는 것을 정확하게 질문하고 무엇을 명확히 설명해야 하는지 인식하였다. 학기 후반에는 수학적 탐구와 더불어 학생들의 개별 성향을 더욱 고려하고 수학을 학습하는 과정에서 지적 용기, 정직, 배려, 협력 등의 학문적 인성에 대해 강조하였다. 본 연구는 이러한 연구 결과를 바탕으로 수업에서 수학적 연결뿐만 아니라 사회적 연결을 충분히 고려하여 보다 의미 있는 수학 수업을 구현하는 데 시사점을 제공하고자 하였다.

기존 콘크리트충전 각형강관(CFT) 구조에 사용하는 각형강관은 4개의 판을 용접하여 제작하는 박스칼럼이 일반적이다. 그러나 이러한 강관은 제작효율이 저하되며, 또한 기둥-보 접합부에는 내측 다이아프램과 관통 다이아프램을 용접하는데 특수한 용접기술이 필요하다. 따라서, 얇은 강판을 절곡하는 방식으로 응력집중 위치의 용접을 피하고, 단면효율이 극대화된 내부앵커 돌출형의 용접조립 각형강관을 개발하게 되었다. 용접조립 각형강관은 강관내부에 스티프너가 설치되어 내측 다이아프램과 관통 다이아프램과 간섭이 발생하게 되므로 본 연구에서는 용접조립 각형CFT 기둥-보 접합부로 외다이아프램형식을 채택하고 외다이아프램의 설계식을 제안하였으며, 기둥-보 접합부의 거동을 파악하기 위해 실대형 4개 실험체를 제작하여 구조거동 및 내력을 분석하였다.

Diagrid system has been in the spotlight for its superiority in terms of the resistance to lateral force when applied to skyscrapers. In diagrid system, most of columns can be eliminated because vertical loads (gravity loads) and horizontal loads (lateral loads) are delivered simultaneously thanks to the triangular shape of diagrid. However, lack of studies on connection shape and node connection details makes it hard to employ the system to the buildings. In this study, the structural safety of the node connections in circular steel tube diagrid system which has been considered in the Cyclone Tower in Korea (Seven stories below and fifty-one above the ground) was evaluated using the 4 full-scale specimens. The parameters are the extended length (20 mm, 40 mm & 60 mm), thickness (40 mm & 50 mm).
