In order to enhance national science technology and to secure the origin of creative wealth, there is a need to offer accurate and high quality information with semantic technology. Semantic technology enables to significantly unify information and obtain the wanted information in an easier way. Also Semantic technology is a key technology of the next generation having great ripple effect on the whole of IT. In this paper, We analyze an economic ripple effects in terms of production inducement effect, added value inducement effect, import inducement effect, labor inducement effect of Semantic technology using an input-out analysis of the bank of Korea(2009). We also examine an economic propriety of Semantic technology.

With the arrival of the knowledge information society, records as assets have become increasingly important. As defined in ISO 30300, records must be actively utilized to contribute to organizational management and generate added value. To create added value through records, their utilization must be prioritized. While countries like the UK, New Zealand, and Australia recognize records as assets and propose record assetization policies, specific measures for managing records as assets have yet to be suggested. To address this gap, we analyze Directive (EU) 2019/1024, established by the EU, to facilitate commercial use and promote accessible public information. We derive seven characteristics from the analysis and extract insights from Italian policies and actual implementation cases that reflect them in accordance with the regulations of the EU guidelines. In addition, the correlation between the Public Data Act and the Public Records Act in Korea was revealed, and points that could reflect Directive (EU) 2019/1024 in Korea were derived. Through this study, it is expected that public data will be treated as information assets and serve as a stepping stone for preparing information assetization policies for records.

In an information-oriented and internationalized society of the future, the quality and the price of goods made by each country will be equalized. That eliminates competition. But the design and appearance of products is an important factor in international competition. Indeed, design symbolizes a country's culture visually, and it can show the cultural identity and originality of a nation in international society. And that will play an important part that can contribute to creating added value. It is necessary to revive our people's old lyrical stories which are far away from our memory, and we badly need design development to revive traditional cultural merchandise through visual modernization. In this study, I chose lotus as the subject material of textile design development. And my intention for this study is to reflect Korean traditional cultural value as much as I can, and to develop textile design of Korean images by adding modern scenes. Also, I intend to print them on fabric, and apply them to cultural merchandise including scarves and ties, by using digital textile printing systems. The reasons for doing so, are to create high added value, and to let other peoples of the world, know about our excellent culture.

This paper describes an efficient framework for the extraction of a brain tumor from magnetic resonance (MR) images. Before the segmentation process, a median filter is used to filter the image. Then, the morphological gradient is computed and added to the filtered image for intensity enhancement. After the enhancement process, the thresholding value is calculated using the mean and the standard deviation of the image. This thresholding value is used to binarize the image followed by the morphological operations. Moreover, the combination of these morphological operations allows to compute the local thresholding image supported by a flood-fill algorithm and a pixel replacement process to extract the tumor from the brain. Thus, this framework provides a new source of evidence in the field of segmentation that the specialist can aggregate with the segmentation results in order to soften his/her own decision.

In this paper, we propose a new variable latency L1 data cache architecture for multi-core processors. Our proposed architecture extends the traditional variable latency cache to be geared toward the multi-core processors. We added a specialized data structure for recording the latency of the L1 data cache. Depending on the added latency to the L1 data cache, the value stored to the data structure is determined. It also tracks the remaining cycles of the L1 data cache which notifies data arrival to the reservation station in the core. As in the variable latency cache of the single-core architecture, our proposed architecture flexibly extends the cache access cycles considering process variation. The proposed cache architecture can reduce yield losses incurred by L1 cache access time failures to nearly 0%. Moreover, we quantitatively evaluate performance, power, energy consumption, power-delay product, and energy-delay product when increasing the number of cache access cycles.

This paper describes X.509 certificate profile, which is basic and important element in the PKI. X.509 certificate consists of basic fields, unique identifiers fields(added in version 2 certificate), and extension fields(added in version 3 certificate). extension fields of version 3 certificate supplement basic fields. We describes extension fields value and its meaning in current internet certificate.

A classification was provided of various business models that are currently found in internet electronic commerce(business-to-business as well as business - to consumer). Some of these models are essentially an electronic re-implementation of traditional forms of doing business, such as e-shops. Many others go far beyond traditional business such as value chain integration and seek innovative ways to add value through information management and a rich functionality. Creating these new business models if feasible on]y because of the openness and connectivity of the internet. This study explored independent and industry-backed current and future business models that are emerging in the B2B electronic market industry, as well as value -added service models for the Net market maker industry, The protected rapid growth of B2B electronic market will cause a highly competitive environment. The B2B electronic market that deliver on real lasting value will dominate and ultimately earn for themselves a long-term Place in the landscape of the new economy.

The manufacturing industry is the foundation that drives economic growth, and manufacturing innovation is essential for sustainable growth advantage and the transition into a digital economy. Therefore, major countries actively support the field of simulations, which incorporate information and communication technologies into manufacturing, and announce various policies at the national level along with increasing investment. Simulation technology virtualizes product development processes to replace physical production and experimentation of products, dramatically reducing time and costs. In South Korea, the Korea Institute of Science and Technology Information (KISTI) has supported manufacturing companies for about 14 years by providing relevant technologies. This study uses the input-output table for the Bank of Korea to analyze the economic ripple effect. First, we identified the domestic industrial sector dealing with the supercomputing-based simulation industry. Then we analyzed its ripple effects by dividing them into the production inducement effect, value-added inducement effect, employment inducement effect, and forward/backward linkage effect. Consequently, when the supercomputing simulation budget of KISTI (28.3 billion won, 2007-2020) was set as an input coefficient, the analysis showed 45.1 billion won as the production inducement effect, 24.7 billion won as the value-added inducement effect, and 282 individuals per 1 billion won as the employment inducement effect. This study is significant in that it derived the effects of the inputs by analyzing the economic ripple effects of the projects of KISTI, which have been supporting South Korean manufacturing companies for the past 14 years with supercomputing-based simulations.
