This paper introduces prototype design of 765kV Substation control system based on fiber optics LAN and distributed network protocol. Two major important facts, immunity of any surge which frequently occurs in Ultra High Voltage Substation and the most suitable communication protocol for substation control system, are considered on the system design conception. To meet the first fact, use of fiber optics cable and isolation transformer are considered, and to satisfy the second fact, DNP3.0(Distributed Network Protocol) which is IEC870-5 compatible is adopted.

This study is the selection of optimum forming condition for RP system using ADS. Program using ADS reduces the required time for feedback between design and manufacturing of workpiece. When we produce rapid prototype using RP system, we investigate the relationship between Facetres in system variable number of AutoCAD and circularity of rapid prototype, and we will find optimum forming condition in RP system.

Level 0: The Marekting Buzzword : □Confusion between DMU and Visualization □Having a Mobile Data Viewer/Analyser is Anyway a Prerequisite Level 1: Digital Pre-Assembly (DPA): □Building Digital Prototype before Physical Build □Usually a job for Packaging or Prototype Teams □Usually no time Left to take Feed-back into account before Actual Build Level 2: Design in Context: □All Designers within Car Maker do Local DMU before DPA Level 3: Design in Extended Context □Design in Context Expanded to Suppliers(omitted)

Pantograph of high speed rolling stock is one of the key components that transfer of associated technologies was blocked fundamentally from advanced nations. In this study, main technologies related to development of prototype pantograph installed on prototype test train developed according to the project "Development of high speed railway technology" are presented. Status of current korean technologies is explained by presenting developed technologies and applications during the past 6 years from concept design to test and evaluation.

This paper shows the results of exterior and interior design of a prototype test train(HSR 350X) which was developed in R＆D project titled "Development of High Speed Railway Technology". The prototype test train, which has two power cars, two motorized trailers and three trailers, is now being tested on high speed line. The improved conceptual design work of a new commercial train and next generation′s train is also peformed for future needs.

Bio-diesel applications seem to be extended due to bio-diesel policies and changes of agricultural environment. This study was conducted to develop a rapeseed reaping equipment attachable to the conventional combine. This paper was intended to report concept design, process and manufacturing of the prototype rapeseed reaping equipment. For concept design, physical properties of "SUNMANG", which is a typical rapeseed as bio-diesel materials, were considered. The designed prototype rapeseed reaping equipment consisted of wide-width plates, finger type knifes, side cutter knifes and drive equipments. The wide-width plate is 2.1 m wide, 0.7 m long, and 0.002 m thick. The finger type cutter knifes have 14.5 fingers, 30 knifes, and the specification was 7.6 cm of pitch, 8.3 cm of length and $21^{\circ}$ of cutting angle. The side cutter knifes consisted of a hydraulic pump, a hydraulic motor, a flow control and a relief valve, a hydraulic hose, a driving equipment and a reciprocating cutter knife. The 18 reciprocating cutter knifes were 137 cm long and knife pitch, knife length and cutting angle were 7.7 cm, 10.5 cm, and $18^{\circ}$. Prototype weight of the rapeseed reaping equipment was heavier by 272 kg when compared with the manual reaping equipments. Load distributions of left and right side showed 50% and 49%, and those of front and rear side showed 64% and 36%. Static turn-over angles in left and right of the prototype were $38.1^{\circ}$ and $38.7^{\circ}$, respectively. The designed prototype rapeseed reaping equipment was properly mounted at the front of a conventional combine.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. Thus, design, comfort and economical efficiency are important factors of shoes. Consumers can choose suitable shoes for their feet in off-line shopping. However, in on-line shopping, because they can not wear shoes, compare to the off-line shopping, there are many problems in internet shopping. First, consumers can get limited information of shoes because they must search information of purchase without other's help. Second, because consumers can not get important information such as design, size and a comfort of wearing, they can not make a careful decision. Above these, the solution of user-oriented internet shopping is development of new type of prototype which is accessible to user and to offer visual information through 3D-virtual reality. The purpose of this study is to develpoment of shoes easy-order prototype so to reduce of internet shopping risk and offer to shopping convenience. Contents of the new prototype are as follows; 1. Consumers can print out a foot shaped plane figure and compare it to their foot. If the size of printed sheet is not proper, consumers can choose another size. Through this step, they can get their own size. 2. In 3D-virtual reality, consumers can get a various visual information. So they feel wearing comfort indirectly. It is expected that the result of this study would be an important case study to develop of shoes' easy-order prototype for a disabled person.

This study intends to implement a OPAC prototype for digital kids. To the end, this study applies prototyping techniques that design, evaluate and improve an early sample model. Included in this study are as follows: (1) design a conceptual model of new OPACs based on the information need analysis of digital kids, (2) implement a OPAC prototype with WordPress 4.2 version, (3) evaluate the prototype OPAC from the viewpoint of digital kids and children librarians, and finally, (4) suggest the improved model and implementational strategies for kid's OPAC. 6 fourth and fifth graders in the elementary school and 5 children librarians in public libraries participate in the final evaluation process.

Reflecting the consumer's desire to look young, the "down-aging" trend, which blurs the distinctions between age groups, is the latest craze in the fashion market. The popularity of this trend made brand identities similar, resulting in customers becoming more interested in segmented notions of fashion (in terms of the story, design, high-quality material, etc.) regarding the product, and in particular, focus has become oriented to the fitness to the human body. In this sense, the researcher aimed to develop the prototype of a slim-fit tailored jacket that fits the standard somatotypes of women in their 30s well. For the purpose of this research, slim-fit tailored jackets from existing brands were collected and analyzed, and a subsequent wearability test was conducted based on the standard somatotype of women in their 30s. The research patterns were prototype of the developed slim fit tailored jacket are bust size of 3.8 cm, waist of 7 cm, and hip size of 3.8 cm. Then the research patterns were selected to develop the prototype of a properly fitting slim-fit tailored jacket. As outlined above, the development of a slim-fit tailored jacket prototype for the standard somatotypes of women in their 30s was conducted by solving the fitness issues of existing brands in order to produce properly fitting jackets that satisfy consumers.
