There are some common and broad trends in National crisis management system around the world. This article considers that paradigm theoretically. 1) a shift from civil defense to civil protection, 2) 10 principles in sustainable National crisis management system, 3) the collaborative governance of crisis management. Some civil defense problems in National crisis management system are as follows; 1) obscurity of organizational identity through twofold function in civil defense, 2) ineffective organization in civil defense and disaster management system, 3) weakness of competencies in local government, 4) overlook of actual condition in communities and civil defense resources. This article suggests that to provide retired and active private security practitioners, retired law enforcement personnel, and retired military personnel to form a elite civil defense force and to find creative ways to address this pervasive threat which one reasonable and affordable solution would be for the government to take advantage of an existing resource.

In most Asian areas Chinese writing and characters had been used as a unique recording device. The way to account for the circumstance related with the writing system could be twofold. Firstly the races inhabited around Sino-territory actually neither used the type of languages as Chinese - not isolating type but agglutinative one - nor established any independent writing letters. Secondly those people who belonged to the races accepted the writing system of China due to the frequent cultural and economical interchange between them and Chinese people. In Korean peninsula the same situation of linguistic phenomenon had been pervasive. The aborigine of the territory who acquired to use Chinese writing applied their knowledge of the second language to record the facts related with the management of the country. But the grammatical structure of Chines writing and native language showed the remarkable contrast; so, the people of the peninsula managed the specific letter system - in other words, the discrepancy between language and writing. This difference carried on the huge influence on the way of using Chinese writing and characters in Korea. Some scholars of historical linguistics of Korean language considered the alternation of Chinese writing system and characters as "the procedure of nativization" - in which the inflow of characters into Korean and the same one continuously used in China illustrated the large gap of the phonological aspects. The method of reading Chinese characters came to be named as Sino-Korean Pronunciation. In the categorization of Chinese characters' pronunciation Sino-Korean Pronunciation was also categorized as the Eastern Pronunciation(東音). It indicates the sound of Chinese characters which has been historically adapted to the phonological system of Korean language. In this paper the main point is to survey the procedure of reception of Chinese writing and characters and that of establishment and alternation of Korean phonetic feature of Chinese writing and characters.

This study presents an ultrasonic location awareness system for the ubiquitous computing with absolute position. The flight time of ultrasonic waves is determined by a period detecting technique which is able to extend the sensing range compared with traditional methods. For location awareness, ultrasonic waves are sent successively from each ultrasonic transmitter and synchronized by radio frequency (RF) signal, where the transmitting part is fixed and the receiving part is movable. To expand the recognizing range, cell matching technique and coded ultrasonic technique are introduced. The experimentation for various distances is accomplished to verify the used period detecting technique of U-SAT system. The positioning accuracy by using cell matching is also verified by finding the locations of settled points and the usability of coded ultrasonic technique is verified. As a result, the possibility of ultrasonic location awareness system for the ubiquitous computing can be discussed as a pseudo-satellite system with low cost, a high update rate, and relatively high precision, in the places where GPS is not available.

Quality management has become an pervasive philosophy in most sectors of business. Specific movements such as statistical quality control, quality circle, total quality management, and quality management system have become embedded in business organizations. Only the companies with competitive edge can survive in the competition in global market. KSA(Korean Standards Association) established in 1962 has launched all kinds of quality education, quality standard certification service for business, and KNQA(Korean National Quality Award) system. This article considers quality competitiveness excellent company award among KNQA. We performed a statistical analysis of audit data for quality competitiveness excellent company for three years, from 2015 to 2017. By using ANOVA and two sample t-tests, the average scores of 13 evaluation fields were significantly different depending on company size and type. We proposed ways to improve the current hall of fame system. We discovered that the average scores of 13 evaluation fields in the audit data according to years and hall of fame status were not significantly different. We also showed linear relationships among 13 evaluation fields by correlation analysis and obtained an estimated linear regression equation : Business Performance, which is a comprehensive index, as a dependent variable was significantly related to Customer Focus and Product Liability as regressor variables among 13 evaluation fields by regression analysis.

Large data handling is one of critical issues that the data mining community faces. This is particularly true for computationally intense tasks such as data clustering. Random sampling of instances is one possible means of achieving large data handling, but a pervasive problem with this approach is how to deal with the noise in the evaluation of the learning algorithm. This paper develops a new optimization based clustering approach using an algorithm specifically designed for noisy performance. Numerical results show this algorithm better than the other algorithms such as PAM and CLARA. Also with this algorithm substantial benefits can be achieved in terms of computational time without sacrificing solution quality using partial data.

With the advance of network and software infrastructure, Grid-computing technology on a cluster of heterogeneous computing resources becomes pervasive. Grid computing is required a coordinated use of an assembly of distributed computers, which are linked by WAN. As the number of grid system components increases, the probability of failure in the grid computing is higher than that in a traditional parallel computing. To provide the robustness of grid applications, fault detection is critical and is essential elements in design and implementation. In this paper, a OGSA based process fault-detection services presented to provide high reliability under low network traffic environment.

In recent years, the progress of Network and Web technology is made more demanding and pervasive of Web-based information systems. At the same time, the complexity of web applications has grown significantly. As a result, developers, users, and other stake-holders have become increasingly concerned about the manner in which complex Web-based systems are created as well as the level of system performance quality, and integrity. In this paper, we propose an efficient developing process and modeling environment of the web applications. Also, after modeling web application using the diagrams, web pages are extracted automatically. It is aimed at facilitating the desist implementation and maintenance of large, complex web applications and the reuse of previously gathered design experience.

DSP-based implementation is pervasive in wireless communication parts for systems and handsets according to developing high-speed and low-power programmable Digital Signal Processor (DSP). In this paper, we present a real-time implementation of multi-channel Adaptive Multi-rate (AMR) speech coder. The real-time implementation of an AMR algorithm is achieved using 32-bit fixed-point TMS320C6202 DSP chip that operates at 250 MHz. We performed cross compile, linear assembly optimization and TMS320C62xx assembly optimization for real-time implementation. Furthermore, speech data input/output function and communication function with external CPU is included in an AMR speech coder. The AMR Speech coder developed using DSP EVM board was evaluated in ETRI IMT-2000 Test-bed system.

Pervasive augmented reality (AR) technology can be used to efficiently search for the required information regarding products in stores through text augmentation in an Internet of Things (IoT) environment. The evolution of context awareness and image processing technologies are the main driving forces that realize this type of AR service. One of the problems to be addressed in the service is that augmented objects are fixed and cannot be replaced efficiently in real time. To address this problem, a real-time mobile AR framework is proposed. In this framework, an optimal object to be augmented is selected based on object similarity comparison, and the augmented objects are efficiently managed using distributed metadata servers to adapt to the user requirements, in a given situation. To evaluate the feasibility of the proposed framework, a prototype system was implemented, and a qualitative evaluation based on questionnaires was conducted. The experimental results show that the proposed framework provides a better user experience than existing features in smartphones, and through fast AR service, the users are able to conveniently obtain additional information on products or objects.
