In order to establish an autonomous driving environment, it is necessary to study traffic safety and demand prediction by analyzing information generated from the transportation infrastructure beyond relying on sensors by the vehicle itself. In this paper, we propose a real-time traffic information generation method using sensor convergence technology of transportation infrastructure. The proposed method uses sensors such as cameras and radars installed in the transportation infrastructure to generate information such as crosswalk pedestrian presence or absence, crosswalk pause judgment, distance to stop line, queue, head distance, and car distance according to each characteristic. create information An experiment was conducted by comparing the proposed method with the drone measurement result by establishing a demonstration environment. As a result of the experiment, it was confirmed that it was possible to recognize pedestrians at crosswalks and the judgment of a pause in front of a crosswalk, and most data such as distance to the stop line and queues showed more than 95% accuracy, so it was judged to be usable.

Technological systems are defined as network(s) consisting of technological infrastructure, industrial organization, and institutional infrastructure. This paper reviews SEMATECH in the U.S. and VLSI Program in Korea as a technological system for semiconductor, which is an advanced technology. Several issues are addressed : how did they get started\ulcorner ; how have they been evolved\ulcorner ; how have the actors and institutions within the system interacted\ulcorner ; what role has the government played in that process\ulcorner Both systems were created by their government, respectively, and they have been evaluated as successful. However, while SEMATECH became complete eough in terms of technological infrastructure, industrial organization, and institutional infrastructure to generate sufficient increasing returns to develop in a self-reinforcing way, a series of VLSI program in Korea is still operated discontinuously under the government subsidy. SEMATECH is more flexible and stable than Korea's VLSI program in that the system has a centralized structure and has been managed and staffed by industry substantially. In addition, both cases show that a technological system may evolve having connections with foreign technological systems and local sub-systems beyond nations, regions and industries. Many other similarities, contrasts, and insights for technological policy from each country's experiences are presented.

With due to the recent development of USN (Ubiquitous Sensor Network) technology, a monitoring system has been developing for assuring the structural integrity of infrastructure through normal or long term measurements during their lifetime. An accident such as a collapse of infrastructure may cause not only loss of life but also damage to the economy of the nation. In order to enhance the availability of infrastructure and to be able to maintain their lifetime, it is necessary to monitor and to evaluate continuously the structural integrity throughout their entire lifetime. The purpose of this paper is to develop a monitoring system integrated with evaluation function based on the ubiquitous technology. The most essential part of this study is focusing more on developing a specific module convertible to A/D, which is to enhance the applicability of sensors that had not been applied to existing monitoring systems. Conclusively it has been successfully enhanced to make more diverse the number of sensors and measuring techniques for the monitoring system.

North Korea has stressed Information Technology in policy fostering science as Kim Jong-il has been interested in IT industry. In view of development of e-business in Northeast Asia, South Korea is to cooperate with North Korea. It is the time to look into the current situation, strategy and issues of IT in North Korea. Although North Korea is forced to select the development of IT Industry as growth engine, the problems in the IT Infrastructure are as follows:lack in communication infrastructure, lack in diversity of software, low level of hardware, limited use of internet. This paper deals with the IT Infrastructure of North Korea and IT and e-Commerce Cooperation, introduction of e-Trade between South and North Korea.

Organizations today depend and thrive on timely, accurate and strategically relevant information. Business analytics (BA) holds the key to many of these issues. This paper validates a model on how the usage of BA leads to operational efficiency. We identified the factors of basic analytical usage from the Business Capacity Maturity Model (BCMM). The scope of the study is restricted to the Information Technology Infrastructure and Application management domain. A survey was conducted among the managers of the IT companies in Bengaluru, India. The results showed a significant influence of data-oriented culture and BA tools and infrastructure on BA usage. We found a significant influence of BA usage and pervasive use on operational efficiency. The speed to insight is still not practised in organizations. The awareness level of analytical skills in organizations is very low.

Administrative works of local governments in Japan always have been led by central government. Local government organizations have gotten used to control of central government, whose organization is divided vertically into divisions. Such organizations as lack of cooperation of each administrative division could not define strategic goal appropriate for their district independently and could not give an efficient and optimized solution to their strategic goal. Under existing management system, it will be difficult for local governments to rapidly adapt to changing society. Under these circumstances, it is necessary for local governments to structure new management system independent on central government's instructions in order to manage appropriately.

Continuously expanding information technology is changing the world in which our students live. Many schools are using this new technology and many schools are contemplating the use of this new technology. The ways in which teachers and students work, and their dependence on information technology, have evolved significantly-increasing the importance of getting the information technology infrastructure right in schools. Yet, all too often, most of schools are unable to take full advantage of the opportunities that information technology offers since those designing and fitting out school buildings have failed to consider information technology adequately. This study is to guide the physical design of practical networked schools. In this paper, we present the ways to achieve architectural solutions to the manifold problems associated with accommodation of information technology in schools. The practical guidelines for planning and managing information technology infrastructure-that is, the spaces and services provided in the school building to support the user' information technology requirements-are offered. Adherence to these guidelines will provide a substantial degree of adapability and flexibility in school buildings.

A methodology based on distributed fiber optic sensors is proposed to detect the lateral buckling for subsea pipelines in this study. Uncontrolled buckling may lead to serious consequences for the structural integrity of a pipeline. A simple solution to this problem is to control the formation of lateral buckles among the pipeline. This firms the importance of monitoring the occurrence and evolution of pipeline buckling during the installation stage and long-term service cycle. This study reports the experimental investigations on a method for distributed detection of lateral buckling in subsea pipelines with Brillouin fiber optic sensor. The sensing scheme possesses the capability for monitoring the pipeline over the entire structure. The longitudinal strains are monitored by mounting the Brillouin optical time domain analysis (BOTDA) distributed sensors on the outer surface of the pipeline. Then the bending-induced strain is extracted to detect the occurrence and evolution of lateral buckling. Feasibility of the method was validated by using an experimental program on a small scale model pipe. The results demonstrate that the proposed approach is able to detect, in a distributed manner, the onset and progress of lateral buckling in pipelines. The methodology developed in this study provides a promising tool for assessing the structural integrity of subsea pipelines.
