The purpose of this paper is to produce color harmony code based on color harmony prototype in terms of environmental color design. This paper proposes ways of categorizing more accurate color harmony prototype through digital image processing by the computer program called the Color Syntax. The method of analysis adopted in this paper is pixel based color image processing. The study suggests color harmony prototype which are categorized by a color harmony angles. These angles represented internal relations between colors. This study describes development processes of color harmony prototype which is a basis for creating color harmony codes. Development processes of color harmony schema consists of color analysis, color codes generation and color selection. Also, how to analyze color images and to chose suitable harmony color codes among various codes are main research issues. As a final result, 109 color harmony codes have been obtained. These code numbers are suggested through rotating 2 color pairs in a 360-degree arc in the same color harmony angles, the codes which is applicable to the color harmony schema previously developed. This color harmony codes will produce better color environment in a sense that it will help designers to maximally reduce their time consumption, and the results of their designs will also be related to the use of proper color for regional environments.

A prototype needs to show the requirements of the users and help them understand better. These prototypes are useful in a variety of industries. But most existing prototypes depend on the visual representation. This method of visual expression has a limitation, which can't express the detailed contents. This paper suggests an expression method of linguistic formation as an alternative. The prototype of linguistic expression can demonstrate the detailed contents of the requirements, keep a good communication among those who are related to the project, and allow them to deal with a large number of possible problems which may happen from the developing process. As it's also easy to make the developing process documented, the prototype will be helpful to improve the software development.

This paper presents a low-cost prototype for monitoring online the maximum power produced by a domestic photovoltaic (PV) system using Internet of Things (IoT) technology. The most common tracking algorithms (P&O, InCond, HC, VSS InCond, and FL) were first simulated using MATLAB/Simulink and then implemented in a low-cost microcontroller (Arduino). The current, voltage, load current, load voltage, power at the maximum power point, duty cycle, module temperature, and in-plane solar irradiance are monitored. Using IoT technology, users can check in real time the change in power produced by their installation anywhere and anytime without additional effort or cost. The designed prototype is suitable for domestic PV applications, particularly at remote sites. It can also help users check online whether any abnormality has happened in their system based simply on the variation in the produced maximum power. Experimental results show that the system performs well. Moreover, the prototype is easy to implement, low in cost, saves time, and minimizes human effort. The developed monitoring system could be extended by integrating fault detection and diagnosis algorithms.

This study was to develop the patterns based on the study of commercial Cheollik dress pattern analysis that verify the effects of pattern improvement by performing wearing evaluations. The commercial Cheollik dress pattern analysis was divided into A type composed of a traditional hanbok flat sleeve type and B type composed of western three-dimensional sleeves type. The prototype pattern of A type and prototype pattern of B type were fabricated after modifying and supplementing the pattern on the basis of precedent research. Appearance evaluations and mobility evaluations were also conducted. In the evaluations of the appearance, the prototype pattern in both A type and B type rated better than the control pattern in all items, so it can be judged to be a pattern that creates a better appearance in terms of allowance and design ratio. In the evaluations of the mobility, the prototype pattern was more convenient and a functional pattern with better scores in both A type and B type. If the Cheollik dress prototype patterns developed in this study are distributed, the Cheollik dress will be easy and comfortable to wear as a casual wear, which will help to make dailyization and popularization of Hanbok.

A prototype of remodeling floor plans are proposed in this study. They are researched base on the majority floor plan type which forms 19% out of representatives 1st-Phase New Town Aged Apartment compositions. In order to examine possible scenarios of the prototypes, prototype planning model is derived from the president studies on aged apartment remodeling. The prototype plans reflect residents' preference survey and lead 6 different kinds of prototype plans regarding 3 different remodeling scenarios. Prototypes consider characteristics of multi-complex buildings and households which applicably various remodeling planning options; story-Increase remodeling, residents custom remodeling etc. The study has significance to be basic planning materials for remodeling of association and local government.

Test methods by hydraulic oil or vehicular live load have been used for structural evaluation of prototype bridge. However it has been reported that the use of hydraulic jack has some disadvantages for the view of safety and economy, and the complete structural evaluation through each loading state can not be accomplished blocks is presented to overcome those demerits. To verify the application and safely of the use of concrete weight blocks during each loading state, it is applied to prototype deteriorated bridge. As a result, it could be evaluated the structural behavior completely using the concrete weight blocks

Superconducting power cable is one of the most promising energy application of high-Tc superconductors (HTS). Thus, we investigated previously the characteristics on electrical and mechanical Bi-2223 Ag sheathed tape. And a prototype HTS cable have been designed, constructed and tested. The result shows that the transport current of HTS cable (1, 19-filament) in LN2 was 116[A], 240[A], respectively. And AC loss of HTS cable(19-filament) was 1.7 [W/m] in 240 [A] loading.
