Mechanical Characteristics Analysis of Structural Light-weight Aluminum Foam
Ma, Jeong Beom ; Lee, Jeong Ick ;
Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 1~6
Aluminum foam is one of the representative light-weight materials. In this study we analyzed the mechanical properties of the aluminum foam structures. Aluminum materials with pores have novel mechanical characteristics such as flame retardancy, damping, and energy absorption which are superior to those of polymer foam. Furthermore its reusable properties draw considerable interests. General properties, energy and acoustic absorption will be investigated and future research issues such as binding techniques of foam materials with other structures will be discussed through foam application examples.

Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 7~14
This paper deals with the efficient management for the intelligent distribution system related with the renewable energy sources, using the wire-wireless monitoring and control device. This device is mainly composed of 2 sections. One is monitoring device with the Autobase S/W and the other is control device using PLC. This paper proposes a wire and wireless monitoring and control device which can monitor and control the 50Kw PV system installed remotely (about 1Km) in the campus of the Korea University of Technology and Education. By the analysis of PV output characteristic using the device proposed in this paper, it is confirmed that the device can contribute the maintenance of PV system and also the establishment of Smart Grid.

Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 15~23
This paper deals with the analysis for the operation characteristic of PV 3 phase inverter, considering the state equation through d-q coordinates transformation, and proposes an algorithm of controlling current using PI(Proportional Integral) controller to control the output and the theory algorithm of sinusoidal PWM method to design inverter. And also this paper performs PV modelling using PSCAD/EMTDC S/W which is commonly used in analysis of distribution system and confirms effectiveness of the modelling proposed in this paper by analyzing and comparing the EMTDC/PSCAD simulation result with the theoretical method.
Expansion of the Web Space
Kong, Heon-Tag ; Ko, Sung-Bum ;
Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 25~32
Current Web space does not provide standard integrated environment. This, especially in case of large task, can be a cause of low performance of task processing. We proposed an integrated space(called SB space) in this paper through which various actors can share their mutual process in processing a task together. SB space can be installed as a Web site and can be used effectively with Web space. This actually means the expansion of the Web space, which allows us to improve the productivity of the Web space notably. In this paper, this is proved through a concrete case study.
A Study on the Promotion of Plaza in Underground Passage Shopping Centers : Focused on underground shoppping center connecting with subway station in Suwon
You, Hak-Soo ;
Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 33~38
This study is find out the how promotion is handled by understanding the notion and the characteristics of the underpass market in the underground space by comparing those of other ours. However, the underpass market of suwon needs to remodeling. Most of all, there are problems on not having enough ensured environment.
The Study for the Image Quality Measurement in IPTV
Hong, Sung-Hwa ; Jung, Suk-Yong ;
Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 39~43
The research of image quality estimation standard and the image quality change according to the network traffic load increase at IPTV multicasting service is necessary because the concern of IPTV(Internet Protocol TV) service become active recently. General quality indicators for imaging services should represent users' quality of experience. To do this, it should be represented the quality from the point of view of users. It should be developed the QoE measurements to represent the quality of users. Accordingly, we study an algorithm for how to be investigated QoE.
A Study on The Development of Process and Equipment for Heat Radiating Module Nano-Tube Manufacturing System
Choi, Kab-Yong ;
Journal of the Korea Convergence Society , volume 2, issue 3, 2011, Pages 45~50
High performance heat transfer channel is necessary to discharge operating heat of computer and high integrated circuit, refrigerator and air conditioning system. Nano-Tube is useful module witch is able to cope with heat transfer problems. The purpose of this study is to develop the process and manufacturing system for Nano-Tube. Since the Nano-Tube which is used in our country is imported, this study will contribute the development of Nano-Tube technique and economic profits with import substitute effect. This study show the procedure of process and manufacturing system development.
