The industry field training course are offered a opportunities for industrial experience to students and Companies can take advantage of advanced workforce with minimum cost. Universities are taking a new collaborative educational systems that require on-site industry for the 21st century. Therefore, in this thesis, We intended to analyze factors influencing satisfaction of people studying in a situation that industry field training has been required to be a mainstream system of education in the midst of trend of changing paradigm of university education recently, and to suggest some possible solutions for industry field training at industrial complex campus.

The purpose of this study is to determine the rapid saving of life through the drones when natural disasters such as earthquake and fire occur. Drones are equipped with riders, temperature, hazardous gas sensors and wireless cameras are registered with the application server for monitoring the disaster site and real-time monitoring functions are performed to identify the situation on site before rescuing personnel are active. When monitoring finds a person to save, the application server provides real-time image information for effective life-saving.

Field data monitoring systems such as renewable energy generation and smart farm integrated control are developing from PC and server to mobile first, and various wireless communication and application services have emerged with the development of IoT technology. Low-power wide-area networks are services optimized for low-power, low-capacity, and low-speed data transmission, and data collected in the field is transmitted to designated storage servers or cloud-based data platforms, enabling data monitoring. In this paper, we implement an IoT repeater that collects field data with a single device and transmits it to a wireless carrier cloud data flat using a low-power wide-area network, and a monitoring app using it. Using this, the system configuration is simpler, the cost of deployment and operation is lower, and effective data accumulation is possible.

As a result of analyzing the fire accident of the Jecheon complex that occurred at the end of 2017, there have been many casualties due to delays in checking the location information of isolated people. In order to prevent such an accident, various research has been conducted to estimate the location of requesters by means of detecting wireless communication information of mobile phones existing at disaster sites. The main concept is to detect an RF signal of a mobile phone at fire sites and, based on this, precisely estimate the location of the mobile phone on the LOS/NLOS. However, it is difficult to get visibility at fire sites due to smoke and the fire. Therefore, apart from estimating the location of requesters, a research is also needed to determine the direction of entry within fire sites. In this paper, we propose a method to determine a direction of entry to provide effective rescue activities using wireless communication information of mobile phones.

We study the RFID network system in a construction site, and study the connection method between the RFID network system and the integrated information system of construction material. Moreover, we developed a prototype of the construction site RFID server for the management of construction materials and performed the pilot application in a construction site. Through the pilot application, it was known that the proposed RFID network system can be more usefully applied in the construction sites. The results of the pilot application show that the RFID network system is faster, more accurate, and more reliable than the existing system of information management and achieves improvement in construction productivity.

침수상황감시/현장안내시스템은 핸드폰망(CDMA)등 다양한 통신채널과 이들의 DTMF, SMS, Data 통신 등을 활용하여 수위 등 현장위험 상황을 실시간으로 감시 위험요인 발생 시 비즈니스 룰(Business Rule)을 이용 자동으로 현장안내 및 관리자, 지역주민, 수문 인근 경작지 농민에게 SMS를 이용 즉각 위험 상황을 전달하고, 상황실에 현장 상황 자동표출을 통하여 관계기관 및 국민들이 재난상황에 신속히 대응할 수 있도록 하는 시스템이다. 지방자치단체에서 재난상황 관리에 있어 유형별 표준행동 매뉴얼을 관리 시군구재난관리시스템을 이용 운영하고 있으나, 많은 분야별 자료들이 행정적인 업무지시 및 응답에 치중되고 있는 게 현실이다. 이에 지방자치단체에서 관리중인 배수문, 잠수교, 하상주차장 등 위험지역의 침수상황을 실시간으로 감시하며 공무원, 민원인, 인근주민에게 상황단계에 따른 안내 및 관리에 대한 업무프로세스는 상황에 따른 변화가 있어 단순한 프로그래밍에 의한 전산화하기 힘들다. 본 논문에서는 재난전문가의 전문지식을 적극 활용하여 다양한 상황에 대처할 수 있는 BRMS(Business Rule Management System)를 이용하여 침수상황감시/현장안내시스템의 설계를 제안하고자 한다.
