Recently, with a progressive development of hardware of computer, the internet and network technology, the environment of construction varies rapidly due to increase the complex form in structure shape and system. With variations, the CAD system for design and products also varies from 2D system to 3D system. This study mainly deals with the methodology of automatic connection design of 3D CAD system, steel connection system (XSteel) using macro. First, using design program in the steel connection system, Xsteel, the joint connection macro will be made up and established the detail classes of design. The next, Database Program (Converter Program) related to the general structural analysis program (MIDAS) and the steel connection program (Xsteel) is constructed for data interface between two programs. From this study, if the merits of 3D CAD system and converter program are utilized well, it is expected that the time needed in modeling and the amounts due to material loses decrease gradually.

Objective: This study aimed to develop and apply the home connection program for promoting the mathematical interaction of parents of 3-year-olds. Methods: We surveyed questionnaires for 36 parents and interviewed 3 parents of 3-year-olds for the development of the program. Twenty-one 3-year-olds were selected as participants in the program. Quantitative data from a checklist for parent's mathematical interaction were analyzed using repeated measures ANOVA. Qualitative data from self-evaluation of teachers and parents were categorized and analyzed in terms of meaning. Results: Based on the home connection program, the session were provided in the following order [educare center activities ${\rightarrow}$ home-linked activities ${\rightarrow}$ home+educare integrated activities] and in each session, the three-step course [sharing of thinking ${\rightarrow}$ gathering of thinking ${\rightarrow}$ broadening of thinking] was applied. Implementation of this program led to promoting parental mathematical interaction. Conclusion/Implications: This study will lead to follow-up studies that reveal positive effects of our program.

Shear wall-frame system is one of the most, if not the most, popular system for resisting lateral loads. The core is the primary lateral load-resisting systems, the perimeter frame is designed for gravity loads, and the connection between perimeter frame and core is generally a shear connection. Specially, single plate shear connection have gained considerable popularity in recent years due to their ease of fabrication and erection. Single plate shear connection should be designed to satisfy the dual criteria of shear strength and rotational ductility. An experimental program was undertaken to evaluate seismic behavior of single plate shear connection. The main test variable is the reinforcing detail of connection. Through the experimental program, the cyclic behavior of typical and reinforcing single plate shear connection was established.

The connection with combined cross diaphragm is developed for the connection of square CFT column and steel beam and proposed to be used for the frame with asymmetric span length. The structural characteristics of this connection lie in the penetration of the beam flange in the direction of major axis through the column for the smooth flow of stress. The purpose of this study is to analyze the dynamic behavior and stress flow of suggested connection and to evaluate the resistance to shock of connection. Four T-type CFT column-to-beam specimens; two with combined cross diaphragm and the others with interior and through diaphragms, the existing connection types, were made for cyclic load test guided by the load program of ANSI/AISC SSPEC 2002. The results show that the proposed connection is more efficient than existing ones in terms of strength, stress flow and energy absorption and satisfies the seismic performance required in the region of weak/moderate earthquakes.

우리 주변에는 수학영재 교육 수혜자는 아니지만 수학적으로 유망성이 있는 학생들이 많이 있다. 이들의 수학 유망성을 계발 신장시키기 위해서는 정규교육과정과 차별화된 학습 프로그램과 교육의 기회를 제공하는 것이 바람직하지만 현실적으로 한계가 있다. 학교교육과 가정교육은 상호보완적인 관계를 가질 경우 교육의 효과는 상승한다고 볼 때, 학교와 가정을 연계한 개별학습 프로그램과 집단학습 프로그램을 제공하는 것은 수학 유망성을 신장시키는데 기여하리라 생각한다. 따라서 본고에서는 수학적 유망성이 있는 학생들을 위해 학교와 가정을 연계한 통합 연결형 학습 프로그램의 개발과 그 활용 방안에 대해서 살펴보고자 한다.

When a large-scale load or a new generator is connected to power systems, KPX assesses the effect of the connection on power systems to keep security and reliability standards. As the number of connection requests has been increased, KPX is spending much time for technical assessments of the requests. This paper developed an automatic assessment program to reduce analysis time and enhance simulation accuracy. The program is based on IPLAN and. can be applied to both load and generator network connection requests.

이 연구의 목적은 다양한 접합상세를 갖는 프리캐스트 콘크리트(precast concrete, 이하 PC) 전단벽에 대한 BIM 모델링 절차를 정립하는 것이다. 그 결과 스케치업(SketchUp)의 프로그램과 컴포넌트 기능과 IFC(Industry foundation classes)파일 형식을 이용하여 BIM 프로그램에서 사용가능한 PC 전단벽 패밀리 라이브래리를 구축 할 수 있었다. 스플라이스 슬리브, 볼트 또는 용접접합공법을 이용한 PC 전단벽은 BIM 프로그램으로부터 배근된 철근들의 간섭여부와 콘크리트, 철근 및 철재 재료들의 물량을 정확히 평가할 수 있었다. 평가 결과 용접접합 공법을 이용한 PC 전단벽은 판재, 볼트 및 너트를 사용하였음에도 스플라이스 슬리브로 연결된 PC 전단벽에서 사용된 재료들의 전체물량, 경제성 및 환경영향성이 비슷한 수준에 있었다. 결과적으로 볼트 또는 용접접합 공법은 PC 전단벽에서 적용가능성이 높은 공법이며, 특히 시공성까지 고려한다면 스플라이스 슬리브 공법보다도 더 유용한 연결공법이 될 것으로 판단된다.

The ultimate capacity of end-plate connection is investigated through nonlinear finite element analysis. The example models are divided into stiffened case and unstiffened one. The refined finite element models are analyzed by utilizing a general purpose structural analysis computer program ADINA and the moment-rotation relationships of the connection are determined. The results are compared with the regression equation deduced by Krishnamurthy. It is planned to deduce a bilinear regression equation through a parametric study on various dimensions of the connection.

Middleware offers function that user application program can transmit data independently of network device. Connection management about network connection of module is important for normal service of module base personal robot. Unpredictable network disconnection is influenced to whole robot performance in module base personal robot. For this, Middleware must be offer two important function. The first is function of error detection and reporting about abnormal network disconnection. Therefore, middleware need method for network error detection and module management to consider special quality that each network device has. The second is the function recovering that makes the regular service possible. When the module closed from connection reconnects, as this service reports connection state of the corresponding module, the personal robot resumes the existing service. In this paper proposed method of network connection management for to support fault tolerant about network error of network module based personal robot.
