Digital maps that art the primitive components for GIS has been increasingly used for various applications. Although their production processes has been noticeably improved, particularly, the geographic survey and structural editing processes still depends on the traditional process depending on maps printed on papers. This study thus proposes a new efficient method employing a computerized filed survey system into these processes. We applied this method to producing a digital map ver 2.0 and compare the results nth those based on the existing method. From this comparison analysis, it is shown that the proposed method saves about 5% from the overall cost by reducing the man power and processing steps required for digital map production.

In this paper, we proposed the development of a smart factory intergrated technology education platform using smart factory based CPPS (Cyber Physical Production System) and VR (Vitrual Reality) technology and educational methods using the platform. A platform has been developed to learn how to integrate 3D digital twin and BOP (Bill of Process)-based manufacturing processes. In addition, Digital Twin established a smart factory-based integrated education platform by linking mechanical systems, digital twins, and virtual reality through the OPC-UA server. Based on this platform, the smart factory integration platform is proposed to have individual elements of the smart factory integration platform through BOP-based digital twin simulation, OPC-UA integration, MES system, SCADA system, and VR interworking.

Due to the diversification of lifestyles and the rapid growth of Internet environments since the 1990s, mass customization has been recently accepted as an important trend in the area of clothing and all other areas. In response to mass customized clothing products, global clothing product brands are introducing systems for mass customization such as the application of digital fashion systems that introduced IT technologies such as CAD and 3D scanners. However, studies of planning factors for clothing products applied with digital fashion systems in the area of mass production of clothing products are insufficient. Therefore, this study was intended to analyze the lifestyles of 20-30s that are expected to have the highest demand for clothing applied with digital fashion systems and present basic planning factors according to lifestyles. Through the analysis, three groups that have one of fashion pursuing type, sensory information pursuing type, and practical function pursuing type lifestyles were derived. Based on this result, consumer demand for digital fashion systems and basic factors for product planning were analyzed to present basic planning factors for digital fashion system based customized clothing by lifestyle group. This study is meaningful in that it provided basic data for product planning through digital fashion systems by analyzing the awareness, preference, necessity, and planning factors of digital fashion systems through the analysis of lifestyle types.

Since the onset of the 21st century, digital technology has been widely adopted in various fields of art; it has enabled artists or designers to try diverse and brand-new ways of expression in literally every possible field of art, including painting, sculpture, and other design work. Furniture design is no exception. From the initial design step to the final production of furniture, modern digital skills are broadly utilized, creating a whole new set of designs that would otherwise be hardly conceivable and realizing a highly efficient furniture-making mechanism. More recently, the 3D printing technique, which is called a 21st century alchemy, has been successfully commercialized and is getting more popular, heralding yet another innovative shift in the area of furniture design and production. In this context, this study discusses the background of the furniture design using digital technology, and identifies the correlations between the modern digital technology and furniture design by redefining the concept of such digital technology. By reviewing multiple real-life cases, some of the key digital expressions found in modern furniture design are also analyzed. This study aims at suggesting the reason why digital technology is significant and promising in diverse ways for the development of modern furniture design.

The production management is one of the essential capabilities of the small and medium-sized enterprises (SMEs) in the information technology sector (IT). Therefore, this study empirically analyzed the effects of such important factors as external information network diversity and manufacturing capability on IT SMEs' production management capability. Based on the 310 data collected from Korean SMEs in the IT sector, the ordinary least squares regression results from this study by using the SPSS version 22 have empirically shown that IT SMEs' external information network diversity has a positive and significant effect on their production management capability and this effect is fully mediated by their manufacturing capability. These findings provide a meaningful implication that the positive impact of IT SMEs' external information network diversity is linked to their production management capability through their manufacturing capability.

Personalized production represents the changing production and consumption in the fourth industrial revolution. Manufacturers in each field are making great efforts to introduce this concept, but it is difficult to find a flow of change such as in the craft industry, especially in the workshop system. I will try to measure the possibility of fusing personalized production in the craft workshop in accordance with the changing production and consumption. To do this, we examined the concept and examples of mass custom production, which is a similar system, and defined the customized production. Then, we recognized the production status of the modern craft workshop and consequently examined the possibility of convergence based on two basic points of productivity and communication.

Although cross rolling process has many advantages in forging a joint shaft, an automotive component of front axle unit, subsequent process is necessary to straighten its bending during forging process. In this paper the bending minimization of the joint shaft was studied to eliminate such an additional process. First of all, a characteristic diagram was used to find out factors affecting the bending of the shaft. Also design of experiments was utilized for estimating the influence of those factors. It was found that the phase angle, which is the difference in starting positions between upper and lower dies, was important to minimize the bending of joint shaft and die cooling is necessary to diminish the distribution of bending.

The notion of materiality in architecture has existed throughout its history, and it has begun to discussed in earnest as an important architectural discourse since early twentieth century, when the Industrial Revolution and its consequent mass-production system has fundamentally changed the means and methods of architectural production. However, this traditional notion of materiality is not fully engaged with today's digital paradigm, and not able to inquire into the complex aspects of contemporary architectural process, because their theoretical and perceptional bases are still remaining in modern era. In this shifting context, this study is intended to develop a new concept of digital materiality which corresponding to contemporary digital and material culture. This paper speculates and argues digital materiality as an active ingredients of contemporary design process as well as a comprehensive logical system that negotiate with various geometric conditions. The purpose of this study is to analyze and investigates the distinctive characteristics of Office dA's architectural design process in the digital realm.
