SDH-based SHR networks are the reconfiguration process in case of failure and APS protocol used. In this study, addresses the maximum allowed recovery time in two fiber bidirectional networks. We analyse the APS protocol and derive the Processing time domains of each n order to cope with the maximum reconfiguration time of 50㎳, as specified in the ITU-T standard. We finally analyze the interleaved failures. One is the signal degrade then the signal failure, the other is the signal failure then the signal failure. Any case analysis is carried out. reconfiguration time can be guaranteed.

IMF 체제와 의료시장 개방 체제속에서 경쟁우위와 합리적인 경영환경을 구축하기 위해서는 의료업계에서도 불합리한 구조적 개선과 다변화하는 고객서비스 개선을 위해 병원 조직의 효과성 또는 경영 합리화를 위해 구조조정이 불가피하다. 변화의 대응전략 하나로정보기술(Information Technology)에 의한 HPR(Hospital Process ReEngineering) 방법론을 적용시켜 조직의 리스트럭처링(Restructuring)과 프로세스 리엔지니어링(Process ReEngineering)개선으로 인한 경영환경 변화요인을 분석함으로써 기대되는 학습조직, 유연조직, 가상조직, 네트워크 조직, 인간존중조직의 구성효과와 서비스의 질적 향상, 조직의 재구성, 업무의 재분배,인적자원의 적재적소 배치, 사무환경개선, 업무처리과정이 표준와, 경영환경 개선의 기대효과와 정보기술은 단순한 프로세스의 개선, 효율화가 아니라 새로운 환경에 적합한 최적의 경영도구로 병원의 목적 달성에 간접적이 아닌 직접적인 도움을 주는 성공요인으로 평가하였다.

The knowledge sharing in a knowledge management process is much affecting generation and distribution of knowledge. Especially, the knowledge distribution is being revitalized with the center of social media service like twitter and library service 2.0 in the knowledge-based IT (Information Technology) environment. The present research analyzed the structure and characteristics of a social network inside an organization that is growing like an organism through self-organization through tools for SNA (Social Network Analysis) and multiple regression analysis of independent variables such as 1) a relationship between social network's structure and knowledge sharing, 2) a relationship between structural holes and knowledge sharing influence of centrality, 3) a relationship between individual ability and knowledge sharing of information technology and work recognition.

As technology evolves, Internet usage continues to grow, resulting in a geometric increase in network traffic and communication volumes. The network path selection process, which is one of the core elements of the Internet, is becoming more complex and advanced as a result, and it is important to effectively manage and analyze it, and there is a need for a representation and visualization method that can be intuitively understood. To this end, this study designs a framework that analyzes network data using BGP, a network path selection method, and applies it to the cyber common operating picture for situational awareness. After that, we analyze the visualization elements required to visualize the information and conduct an experiment to implement a simple visualization. Based on the data collected and preprocessed in the experiment, the visualization screens implemented help commanders or security personnel to effectively understand the network situation and take command and control.

Dealing with quntization error in a control system properly becomes much more important as many devices are connected through network and controlled. Thus, in this paper, we study a data rate condition on quantizer to achieve practical stability in a discrete time linear time invariant system with state feedback control. First, required data rate is shown to depend on eigenvalue of the closed loop system, the size of the initial state vector, the magnitude of initial quantization error, and control gain in the absence of process noise. It additionally depends on the maximum magnitude of process noise when noise is not zero. Asymptotic analysis shows that a new design method may be needed to reduce the date rate for a networked control in the presence of quantization error and noise.. We provide a simple numerical evaluation of uniform quantizer and logarithmic qunatizer to assess their characteristics of practical stability depending on data rate in the presence of noise.

This study aims at identifying and prioritizing the application areas for business development of IoT(Internet of Things). In specific, we collected the opinions of the experts on IoT in Korea through the survey based on pairwise comparison, and then we analyzed them using AHP(analytic hierarchy process). As a result, we found that 'Public Safety & Security', 'Automotive & Transportation', and 'Utility & Energy' are the most promising area in realizing IoT-related businesses. Also, we found that the experts had different views according to the positions of their industry in IoT value chain. The analysis showed that the device industry prioritizes 'Public Safety & Security', whereas the network industry does 'Automotive & Transportation'. The experts from the service industry were found to regard 'Utility and Energy' as the most promising commercialization area of IoT.

As technological development continues, platforms with more diverse structures are emerging. Existing research predicts that a new structure based on technology and innovation will affect the two-sided market. This study evaluated the decentralized identifier (DID) platform, a new platform based on blockchain technology, of the importance of this platform from the perspective of the two-sided market. Using the Analytic Network Process, IT, platform, and blockchain experts conducted a dual comparison survey. Data with a consistency ratio value of 0.1 or less were selected and analyzed for 12 data. The research results showed the importance of service quality, policy support, openness, and uncertainty. This study is expected to be used to support the development of strategic decision-making for blockchain and DID platform-based business companies.

From the hazard which it prepares in the hazards increase which it follows in information demand augmentation of information technical development and the consumer from inside systematizing integrity and solubility of information technological resources. inside against a confidentiality. The control against information and a system and a data outside is demanded. From the dissertation which it sees demand function and the structure which do information technical risk management system development it will be able to manage the danger which it infiltrates with the root which is various overview in hazard necessity it investigated the inside and outside of the country instance in the center and it analyzed. And it plans the dangerous civil official integrated process model ultimately as against a hazards it will be able to prepare in the dictionary in order, it put the place objective which it induces.
