The purpose of this study was to suggest a silver blouse design by applying modularization. The precedent study of the researcher was used to analyze the design characteristics that were displayed in domestic and foreign silver blouses. This study was taken as the follow-up research as the module components and range of the silver blouse were set up and it was based on to suggest a silver blouse design with application of modularization. The intention was to base on the module system used in various fields to apply the modularization method on the module design research of silver blouse and as a result, it was derived into 6 types. The traditional design reflected on the characteristic of how the silver generation prioritizes practicality and in order to emphasize this, it will be more effective to apply the fastener and folding method for the development of the design. The contemporary design reflected on the characteristic of how the silver generation prioritizes aesthetics and in order to emphasize this, it will be more effective to apply the module composition method where integration can be made according to the desire of the wearer for the development of the design. The trendy design reflected on how the characteristic of the silver generation wants to look younger and the derived modularization method can be applied freely for expression. Since the range, structure, and formation where modularization can be applied are general, it is implied that there is a need to take sustainable development has to be conducted as the tool that can create different types of design.

In order to positively cope with the international environmental regulations like UNFCCC (UN Framework Convention on Climate Change) and to overcome energy crisis Korea, who depends on import for more than 97% of required energy, needs to continuously proceed to development, spread and expansion of alternativeenergy and then, to cultivate the capacity to keep the balance of demand and supply of energy by itself. In this aspect, the technology of BIPV (Building Integrated Photovoltaic) is the field that the world is most interested in. However, at present, this technology is centered on increasing the efficiency of the module itself so it has lots of problems to be applied to buildings. Application of the integrated PV system in building external curtain wall can obtain much more generation of electric power than in roof-types whose area for installation is restricted, so it is excellent in terms of its possibility of application. Therefore, this paper intends to advance its practical use by proposing how to get integrated PV system which can be applied to building external curtain wall, and how to apply it.

For a System-on-a-Chip(SoC) comprised of multiple IP cores, test control techniques have been developed to perform the internal and external test efficiently relying on the various design for testability techniques such as scan and BIST(Built-In Self-Test). However the test area overhead is too expensive to guarantee diverse test link configurations. In this paper, at first we introduce a new flag based Wrapped Core Linking Module(WCLM) that enables systematic integration of IEEE 1149.1 TAP'd cores and P1500 wrapped cores. Then a simple test control technique, which can interconnect internal scan chains of different cores, is described with requiring least amount of area overhead compared with other state-of-art techniques. The design preserves compatibility with standards and scalability for hierarchical access.

The advanced in semiconductor, hardware, and software technologies enables the integration of more com- plex systems and the increasing design complexity. As system design complexity becomes more complicated, System-level design based on the If block and processor model is more needed in most of the RTL level or low level. In this paper, we present a novel approach fur the system-level design, which satisfies the various required constraints and an optimization method of image encoder based on codesign of function, algorithm, and architecture. In addition, we show an MPEG-4 encoder as a design case study. The best tradeoffs between algorithm and architecture are necessary to deliver the design with satisfying performance and area constraints. The evaluations provide the effective optimization of motion estimation, which is in charge of an amount of performance in the MPEG-4 encoder module.

In FMS (Flexible Manufacturing System) and CIM (Computer Integrated Manufacturing), machine-tools have been the target of integration in the last three decades. The conventional concept of integration is being changed into the autonomous manufacturing device based on the knowledge evolution by applying advanced information technology in which an open architecture controller, high-speed network and internet technology are included. In the advanced environment, the machine-tools is not the target of integration anymore, but has been the key subject of cooperation. In the near future, machine-tools will be more improved in the form of a knowledge-evolutionary intelligent device. The final goal of this study is to develop an intelligent machine having knowledge-evolution capability and a management system based on internet operability. The knowledge-evolutionary intelligent machine-tools is expected to gather knowledge autonomically, by producing knowledge, understanding knowledge, reasoning knowledge, making a new decision, dialoguing with other machines, etc. The concept of the knowledge-evolutionary intelligent machine is originated from the machine control being operated by human experts' sense, dialogue and decision. The structure of knowledge evolution in M2M (Machine to Machine) and the scheme for a dialogue agent among agent-based modules such as a sensory agent, a dialogue agent and an expert system (decision support agent) are presented in this paper, with intent to develop the knowledge-evolutionary machine-tools. The dialogue agent functions as an interface for inter-machine cooperation. To design the dialogue agent module in an M2M environment, FIPA (Foundation of Intelligent Physical Agent) standard platform and the ping agent based on FIPA are analyzed in this study. In addition, the dialogue agent is designed and applied to recommend cutting conditions and thermal error compensation in a tapping machine. The knowledge-evolutionary machine-tools are expected easily implemented on the basis of this study and shows a good assistance to sensory and decision support agents.

In modern society, developing and utilizing safety service and system environments is a very important and great interest. In particular, the provision of safety services to socially vulnerable groups such as children, the elderly, women, the disabled and foreigners has become a social issue. However, since most safety services and systems are applied to the general public, it is necessary to develop systems for socially vulnerable groups. Therefore, in this paper, we developed a system module that processes and transmits data to recognize the situation in real time and respond quickly. To this end, various sensors for real-time situation recognition were designed as integrated modules, and a safety system module was developed to analyze the collected data and transmit the processing results.

Cells of a PV (photovoltaic) module can suffer defects due to various causes resulting in a loss of power output. As a malfunctioning cell has a higher temperature than adjacent normal cells, it can be easily detected with a thermal infrared sensor. A conventional method of PV cell inspection is to use a hand-held infrared sensor for visual inspection. The main disadvantages of this method, when applied to a large-scale PV power plant, are that it is time-consuming and costly. This paper presents an algorithm for automatically detecting defective PV panels using images captured with a thermal imaging camera from an UAV (unmanned aerial vehicle). The proposed algorithm uses statistical analysis of thermal intensity (surface temperature) characteristics of each PV module to verify the mean intensity and standard deviation of each panel as parameters for fault diagnosis. One of the characteristics of thermal infrared imaging is that the larger the distance between sensor and target, the lower the measured temperature of the object. Consequently, a global detection rule using the mean intensity of all panels in the fault detection algorithm is not applicable. Therefore, a local detection rule was applied to automatically detect defective panels using the mean intensity and standard deviation range of each panel by array. The performance of the proposed algorithm was tested on three sample images; this verified a detection accuracy of defective panels of 97% or higher. In addition, as the proposed algorithm can adjust the range of threshold values for judging malfunction at the array level, the local detection rule is considered better suited for highly sensitive fault detection compared to a global detection rule. In this study, we used a panel area extraction method that we previously developed; fault detection accuracy would be improved if panel area extraction from images was more precise. Furthermore, the proposed algorithm contributes to the development of a maintenance and repair system for large-scale PV power plants, in combination with a geo-referencing algorithm for accurate determination of panel locations using sensor-based orientation parameters and photogrammetry from ground control points.
