The era of IoT, which figures exchanging data from the internet between things is coming. Recently, former electric power energy policy paradigm, namely Supply side paradigm, is changing, because electric power energy consumption is rapidly increasing. As new paradigm for this limit, convergence of existing electric power grid and ICT(Information and Communication Technology) will accelerate intellectualization of electric power device, its operation system. This change brought opened electric power grid. Consequently, attacks to the national electric power grid are increasing. On this paper, we will analyze security threats of existing IoT, discuss security weakness on electric power industry IoT and suggest needed security requirements, security technology.

This paper has examined the leapfrogging thesis with the case of catch-up in digital TV by the Korean firms. Despite the disadvantages implied by the technological regime of digital TV and the risks facing early entrants in trajectory choice and initial market formation, the Korean firms had achieved a 'path-creating catch-up' in the sense they chose a different path from the Japanese forerunning firms. As they have been closely watching the technological trends and the standard setting process, there was less risk of choosing the right or wrong technological trajectory. Also, despite the lack of sufficient capability and core knowledge base, the Korean firms had some complementary asset, such as the experience of producing analogue TV, and were able to develop the prototype digital TV and the ASIC chips, given the accesses to the foreign knowledge via overseas R&D posts and acquisition of a foreign company. To secure the initial market size, the Korean targeted the US market from the beginning, and their sources for competitive advantages were the speedy setting up the production system for mass production of products at the initial stage. The initial failure of the Japanese firms and the success of the Korean firms do suggest that the period of paradigm shift, like this toward digital technology, can serve as a window of opportunity for late-comers while penalizing the forerunner.

This study analyses the qualities of digital architecture applying digital technologies by examining the qualities applied to the fashion designs of Husssein Chalayan. The aim of this study is to forecast in what ways the digital influence over fashion will evolve. This study was based on literature and case studies to examine the characteristics of digital architecture, and a case analysis of fashion design was conducted on the collections of Hussein Chalayan that draw heavily from technology. As a result, it was possible to classify the characteristics of digital architecture into five groups - immateriality, interactivity, nonlinearity, liquidity, and hypersurface; in addition, all of these characteristics were found in the works of Hussein Chalayan. The digital paradigm will continue to influence modern architecture and fashion in functional and/ or expressive terms that will continue to strengthen through the further advancement of digital technology.

The leading paradigm of dentistry had been focused on the rehabilitation treatment that identifies active caries, manages them surgically, and restores their original functions. However, changes in the external environment including the current disease prevalence require dentistry to have a paradigm shift. The new paradigm suggests the detection of caries in their earlier stages over the visual diagnosis of cavities, and the reversal of the incipient caries by non-surgical approach. For this to be achieved, a high-technology detection device recognizing changes in the earlier stages which can not he visually observed is needed. Development of early caries detection device has recently become a major issue in preventive dentistry on account of this need, and QLF(Quantitified Light induced Fluorescence) conspicuously stands out among the newly released devices. In this study, the fundamental concept of QLF(Quantitified Light induced Fluorescence) and the possible clinical applications of the earlier intraoral camera model as well as the recently designed digital camera model will be discussed.

Japan Aerospace Exploration Agency has introduced a new terascale clusterd SMP system as a main compute engine of Numerical Simulator III for aerospace science and engineering research purposes. The system is using Fujitsu PRIMEPOWER HPC2500; it has computing capability of 9.3Tflop/s peak performance and 3.6TB of user memory, with about 1,800 scalar processors for computation. In this paper, we first present the performance evaluation results for aerospace CFD applications with hybrid programming paradigm used at JAXA. Next we propose a performance prediction formula for hybrid codes based on a simple extension of AMhhal's law, and discuss about the predicted and measured performances for some typical hybrid CFD codes.

Teaching media is changed by the digitalized new paradigm. This paper present a method of constructing the e-Learning which is very important in now a day. In this paper, we propose the suitable design technical e-Learning which is involved in subject. Also, we propose the important effective learning method and key concept in design technical contents in the e-Learning.

The e-Government in Korea has made such good results as improvement of official work productivity and citizen service quality. However, e-Government in Korea involves many problems and subjects to must solve, especially, at the side of citizen services. Every public organization as supplier provides each service of themselves to the civilians. Citizens feel inconvenience yet, because they must visit and are supplied various civil services to one public affair from several public institutions. When we consider the paradigm shift of the e-Government service, the status and problems of the e-Government in Korea required more better service model to the citizen. To realize the citizen oriented service, the integration and linkage of the system infrastructure and applications among governmental organizations are required. In this changed situation, when new one/non-stop service model of the digital government is developed and launched, the e-Government can supply better service to the citizens. In this study, the model that we suggest is among the new service models of the e-Government, named the Integrated Civil Service Model. The e-Government involving the Integrated Civil Service Model can make more outcome, such as better civil life convenience, cost-effective results by processing time and cost reduction for public affairs of citizens.

In most libraries and information centers, access versus ownership is the new dilemma facing in view of the rapidly change of information technologies, the rising costs of serials, and not equally increasing budgets. And libraries and information centers are now confronted with the fact that the more users bypass the library's resources in favor of the results they can get with an ordinary Internet search engine. The purpose of this study is to analyze a difficult problems related to information resources development in digital world with priority given to accesscentered paradigm, the grounds of an argument and fallacy of physical collection building, and limitations of electronic publication.

As the 21st century is the post-digital era, a mix of the hard digital and the soft analog realm, the school uniform designs for the post-digital generation need to be changed within this paradigm shift. Thus, this study is conducted with the purpose of developing the school uniform design that reflects aesthetic value and sensitivity of the post-digital generation. The definition and background of the post-digital generation is reviewed and the values of this generation are drawn based on the theoretical research. Also, through the survey of 205 high school girls in Seoul, the purchase, wear & fit, and suggestions for improvement of present school uniforms are investigated. Based on the studies above, the guidelines for designing school uniforms for the post-digital generation are established and the products are developed.
