As the shape of stamped part is complicated and as the trend toward light weight continues, the higher level of difficulty is required in making stamping die because of inevitably poor formability. The poor formability can be improved if the material flow during the stamping is carefully controlled. Application of drawbead became commonsense used to retard metal flow of blank into the die cavity at the region where wrinkle is expected. In the study, the concept of beadless stamping process is proposed and the method how to realize the beadless stamping process is presented. The validity of the proposed method is confirmed by the application of the real auto part.

In this study, after we analyzed 44 recent research paper written about obesity treatement, we tried to understand the acupuncture on the obesity treatment of the recent trend. We searched the recent papers with the key word of obesity, obese, and Acupuncture and are limited since 2004 in the search site KISS, KSI. Recently, acupuncture application for obesity treatment were 6 type. Traditional Acupuncture, Auricular Acupuncture, Electro Acupuncture, Herbal Acupuncture, Chi Acupuncture, and Acupoint Catgut Embedding Therapy. Although acupuncture application were effective method to decrease weight and localized fat, they were critical to evaluate to their effectiveness through strict and scientific clinical trials.

Electrodialysis with bipolar membranes (EDBM) has recently gained increasing attention for the recovery and production of acids or bases from the corresponding salt solutions and other high value-added business like food processing and biochemical industry. EDBM possesses economical and environmental benefits and can complex with other process such as ion exchange process, extraction and adsorption. So this paper investigates a brief overview of development for bipolar membrane and EDBM with the practical application.

In the trend of building enlargement, high-rise and irregular shaped building, domestic application of BIM in construction phase is increasing in recent years. BIM that is based on a three-dimensional, requires a specific building expression. Model expression level required for each phase such as design, construction, and maintenance of the construction project can be different. BIM model to apply in practice is difficult because it is not clear to set up the criteria for the expression level of construction BIM model. And it has a limit that is lower productivity in construction project. Therefore, this study considers the way of the improvement and analyzes the application for representation level of construction BIM model through the survey. By analyzing of the survey results, this study will be to present a basis for an appropriate expression level setting of construction BIM model.

The issue is all about the study of warranty data collection and the analysis method to get a reasonable information of the products and improve reliability. In this paper, we consider the classification of warranty data analyses into a parametric and non-parametric analysis and method to get a reasonable information of the products. Also, it is considered the research trend by grouping the relationship among the studies. This study would be used to find the effective application and the condition of warranty data analysis.

Development trend and current status were surveyed for pre-heat-treated high strength cold heading quality (CHQ) wire and it's forming technology. Spheroidizing, quenching, and tempering heat treatments are eliminated by adapting the pre-treated wire, which could reduce energy consumption rate and green house gas emission rate during produce parts requiring high strength. There are some challenging problems to expand application area such as enhancing forming tool life, and preventing delayed failure. Domestic research movement concerning the development and application of the new high strength wire was introduced.

In the past few years, the printing industry has witness a trend that has become ever more defined: due to the advent of digital technology, the production of short print runs has continued to gain in importance. An important initiative for the support of digital work flow in the manufacturing of printed products is CIP4 consortium. CIP4 stands for "International Cooperation for Integration of Prepress, Press and Post-press, it is an association of around forty international companies, mostly manufacturers of prepress, press and post-press, as well as suppliers and users. In this paper, we studied on the acting application of CIP4 work flow.

As the number of electric vehicles (EV) increases, there is an increasing interest in the post-vehicle application of the EV batteries. For the second use application of EV batteries, the state of health (SOH) at the end of automotive service has to be evaluated differently from the automotive perspective. It will be helpful to consider the driving conditions of EVs in understanding the performance deterioration trend of the battery. In this paper, we acquired the battery status information in real time during driving and compared the characteristics by the driving routes. The SOH from the BMS can be rescaled to percentage ratio to give a more general idea about the performance degradation.

Now, the era of information, the rapid acquisition of vast and various information acts as a key role. for the national competitiveness. The smart UAV is brought to the fore as a new future technology which will be able to satisfy the information needs in broad and stereoscopic manner. The smart UAV, with VTOL capability, higher performance, and reliability over the existing technology thresholds, will lead the aerospace technology in the future. In this paper, the technology concept of smart UAV, the necessity of development, and the trend of worldwide R&D are introduced and analyzed. In addition, for the Smart UAV Development Program which is launched by the 21c Frontier R&D program this year, the role and application area of the CFD will be discussed.

The environmental regulation of a product is a global trend. The environmental regulation directives such as RoHS, WEEE, ELV and REACH have impacted Korean export-oriented auto parts manufacturer and affects the export of the product to aboard. In electronics manufacture and auto parts manufacturer, there are different systems for environmental regulation compliance. Nowadays the automotive mechatronics parts in a car are increasing. The HEV and intelligent car will need more mechatronics parts. It is necessary to apply the environmental regulation system of electronics to the automotive parts. In this paper, we proposed the application of PDX standard used in electronic industry to the BOM of the auto parts manufactures and showed an example of generated BOM for selected auto part using PDX. The PDX-based BOM can be used for the recording of environmental substances of the automotive mechatronics part and help the collaboration across auto parts manufactures in accordance with environmental regulation.
