A lot of people were trapped in elevators without power supply when BLACK-OUT situation occurred in 2011. The telephone network of control room connected to the elevators had problem operating poorly. In this paper we propose an ICT based elevator emergency call device prototype system and evaluate the performance of the system. The proposed system quickly responds in emergency situation to guarantee passenger safety. For the goal, firstly the system tries to connect to a control room. If it fails the system attempts to call numbers for emergency contact and a rescue team sequentially. The system is designed to quickly support emergency contact as well. Finally, the information of elevator failure is rapidly transferred to the failure process device by the proposed system.

It is more than 10 years since ICT training learning was introduced to educational curriculum, and it is now time for overall consideration about the result of the education. The most important difficulties that the teachers have are that there are big differences in the level of learning ability. The characteristics of ICT curriculum are its tool and stepwise progress. The main problem of a curriculum with such characteristics is with underachivers. To distinguish ICT underachivers, the present study was developed a distinction tool for investigation: The objects were the students in the 6th grade of the 4 elementary schools in Gyeonggi-do, and inquires were made to find out characteristics. Inquires were also made to the elementary school teachers in Goyang-city to find out the actual instructional situation. A teaching-learning system will be suggested to prevent the occurring of ICT underachivers by analyzing their characteristics. The system consists of a distinction examination module, a teaching-learning module and a feedback module, which are web-based, as well as an off-line actual class module. The purpose of the system is to prevent underachivers in ICT classes, so that the students' ability to utilize computer will be improved to a higher level.

지난 60여 년간은 고전정보에 기반한 통신, 저장, 처리 능력이 비약적으로 발전하였다. 이 과정에서 가장 많이 사용된 방법은 정보소자의 크기를 감소시키는 방법이었는데, 이러한 접근법은 최근에 그 한계에 도달하고 있다. 이러한 한계를 극복하기 위해서 다양한 접근법이 연구되고 있으며, 궁극적으로는 양자역학적 현상에 기반하는 양자정보가 사용될 것으로 예상된다. 양자정보는 크게 계산성과 보안성을 향상시키는데, 이에 따라서 향후 ICT 전반에서 많은 변화가 생길 것으로 예상된다. 본고에서는 특히 양자정보에 기반한 양자컴퓨팅을 중심으로, 양자정보의 발현과 관련한 역사적 흐름, 양자정보에 기반한 정보처리의 핵심요소, 양자컴퓨팅 구현 방법론, 양자컴퓨팅 활용 방법론, 현재의 기술수준을 소개한다. 마지막으로 ICT의 경제의존도 및 사회몰입도가 높은 우리나라가 이러한 ICT패러다임의 전환기에서 과연 무엇을 어떻게 준비해야 하는지도 살펴본다.

Increase in oil prices and building energy consumption has been a great burden for Korea which has significant energy dependence on foreign energy sources. In this context, reduction of building energy consumption, which comprises 40% of total energy consumption, is a very important issue. This research therefore empirically analyzed a hospital "P" that implemented ICT-based energy consumption and cost reduction initiative. The hospital first replaced existing water absorber for heating/cooling air and boiler for heating water with water heat storage heat pump system. This was accompanied by subscribing to different electricity price plans to maximize cost reduction. Secondly, the hospital additionally applied ICT-based optimized control algorithm that considers surrounding factors (external temperature, changes in energy demand). The analysis of these mechanisms indicate that the ICT-based energy consumption and cost reduction initiative for hospitals can reduce energy consumption by 53.6% with replacement of low-efficiency equipment and additionally by 18.2% with optimized control algorithm. The mechanisms will provide energy consumption reduction opportunities for other hospitals and buildings with high energy consumption.

In this paper, we propose an ICT-based smart farm design. At present, the decrease in rural population is naturally inevitable due to the decrease of the total population. The economic burden on each farm grows with increasing labor costs. As a solution to this, the necessity of spreading smart farms using computing resources is emerging. The proposed system utilizes the ICT technology emerging from the Fourth Industrial Revolution. We will use big data analysis to collect a large amount of data and propose a platform for managing collected data and providing efficient services. The proposed platform consists of SOA service layer, middleware layer, resource pool layer and physical resource layer. ICT-based smart farm service can reduce costs and be easy to install and manage because ICT-based smart farm service provides only necessary functions from the user's point of view.

The rail transport system is developing into a smart railroad that pursues intelligence beyond the automation stage of each component in recent years. Smart railways based on ICT (: Information & Communications Technology) technologies such as IoT (: Internet of Things), big data, deep learning, AI (: Artificial Intelligence), and block chain are expected to cause many developmental changes in domestic and foreign railway technologies. In this paper, we look at the domestic and international standardization trends of railway communication technology, which forms the basis of such smart railway system, and discuss the direction for train control technology(CBTC) in Korea's railway transportation system to become a leading technology(UBTC) in the world railway industry in the future.

This paper proposes a safety management method that extracts ETA (event tree analysis) based scenario and combines ICT technology to reduce serious disasters occurring workplace for shipbuilding and offshore plant. The statistics of Safety and Health Agency and (previous)Ministry of Public Safety and Security show that the most frequent accident among the serious disasters related to shipbuilding and offshore plant is falling. The main cause of accidents is absence of a safety belt and safety belt ring. To solve these problems, we create ETA based scenarios to derive results based on safety considerations. Based on these results, we propose a solution by applying ICT technology for accident prevention. Deriving ETA based scenarios and ICT technology, the proposed solutions include a system for detecting the wearing of safety belts and safety helmets, a system for detecting whether or not the safety belts are connected, and a hook system for measuring safety distances. These safety related systems can reduce the probability of death of workers. By preventing accidents using the proposed method, we can reduce serious disasters in shipbuilding and offshore plant and establish systematic safety management.
