  • In most shipbuilding company, cutting procedure is proceed by cutting machine which run by CNC(Computer Numerical Code) data. In our cutting process, all CNC data is created by our nesting post processor system automatically. Among them, in case that cutting piece in the remnant plate, our system creates only one piece CNC data. Because remnant plate is not typical shape, and ship designers don't know remnant plate shape and quantity. In can happen some merit and good point if we modify 1:1 piece NC data by shorten cutting path, reducing cutting time or re-arrangement piece. For modifying cutting data, outside workers have to call to ship designer or have to go to NC control room where control the CNC system and cutting machine. It makes stop work process, and it waste time. In this paper, we introduce a program that can modify and replace 1:1 NC data with continuous or common NC data automatically.

  • This paper investigates the impact of the government R&D expenditure on the IT industry in Korea. The analysis of such impact can be used to derive the policy implications for the IT industry. The contribution of government R&D to the IT industry was analyzed based on the input-output table of the year 1990-1995-2000. The results show that the amount of the government R&D expenditure induced the IT industry to book twice greater production than it would have been in the absence of such government R&D expenditure during the period under investigation. It is also shown that job creation was strongly encouraged in the broadcasting equipment, software and computer-related services. During the period under the study, the composition of the workers in the IT hardware industry remained unchanged while the production increased significantly, which confirms the jobless growth in the IT hardware industry. The results of this study suggest that the government R&D should focus on improving the competitiveness of the intermediate good and parts industry.

  • Integrating computer-aided design with computer-aided fabrication and construction will fundamentally redefine the relationship between design and construction. Rapid prototyping(RP) is evaluated as one of the integration method available but it has been regarded as very expensive and complex design evaluation tool and is only suitable for large mechanical design shops in automobile and aerospace industry. However current status of rapid prototyping is changing since the new generation of RP equipment, less expensive and more user-friendlier, now can be installed and use in design firms. Simultaneously increasing use of 3D CAAD software is also helping to use rapid prototyping widely. It is crucial to acknowledge rapid prototyping technologies are not only for avant-garde architect such as Frank O. Gehry but ordinary 90% architects, who can have benefit from fast and cost-effective technology. With its fast development and adaptation in architectural industry, it is quite necessary to include rapid prototyping education in regular CAAD courses either undergraduate or graduate level.

  • Recently, the drone industry rapidly rises to the surface as the new market leading the future, and it seems that the hot UAV drone market shows the similar trend to that of the smartphone. It is expected that the individual application of the drone is quickly diffused as the smartphone roles of camera and game player with the communication medium. For example, the drone is developed mainly as war weapons, but now it is getting close to our real life as the toy or tool for the aerial photography. In this paper, we studied the education for how to bring the aging population to the drone industry. Previously, the controlling skill and taking aerial photography seemed to have nothing to do with citizen seniors. However, we develop the education for try to show any positive relationship between those, in this paper, thus creating more job opportunities for them.

  • The malignant melanoma accounts for about 1 to 3% of the total malignant tumor in the West, especially in the US, it is a disease that causes more than 9,000 deaths each year. Generally, skin lesions are difficult to detect the features through photography. In this paper, we propose a computer-aided diagnosis algorithm based on deep learning for classification of malignant melanoma and benign skin tumor in RGB channel skin images. The proposed deep learning model configures the tumor lesion segmentation model and a classification model of malignant melanoma. First, U-Net was used to segment a skin lesion area in the dermoscopic image. We could implement algorithms to classify malignant melanoma and benign tumor using skin lesion image and results of expert's labeling in ResNet. The U-Net model obtained a dice similarity coefficient of 83.45% compared with results of expert's labeling. The classification accuracy of malignant melanoma obtained the 83.06%. As the result, it is expected that the proposed artificial intelligence algorithm will utilize as a computer-aided diagnosis algorithm and help to detect malignant melanoma at an early stage.

  • The green IT technology is being introduced in diverse sectors, especially in the data center and green computer sectors. Rack-type PCs, which have been developed by improving the computer hardware, are effective for data centers and large businesses, but they are not usually introduced in small organizations such as small and medium businesses and schools because they require high initial costs. Power-saving PC software enables the inexpensive power control, but the installation of the power-saving software in all computers in the organization is not an easy task. Computer users in the organization are usually not cooperative as they do not think the power-saving cost is directly related to themselves. In this paper, a technique wherein the server has a restriction in providing the IP address to the computers that has no power-saving software is proposed, so that users will cooperate in the PC power-saving system to avoid inconvenience. In order to provide restricted IP address periodically, the server makes a request of power-saving software installation check for user's PC. Proposed technique is more effective ways to save computer energy, because it does not depend on specific systems or organizations.
