In this study, design and manufacture of LFR (Linerar Fresnel Reflector) system was performed for solar thermal absorption cooling. The LFR system was designed considering the expansion and convenience to be installed according to the cooling capacity of the applicable building. Twelve LFR modules with a total reflection area of $204m^2$ were installed. The automatic tracking system was applied to track the sun during the daytime.

Convergence-based Smart Work in Korea started from 2010 with a purpose to improve work-life balance. Up to now the previous research on Smart Work has been studied in the context of the pre-adoption or the adoption stage, and shows some limitations not finding out the effort to manage change, the issues occurred in the process of adopting Smart Work, and the performance after adopting Smart Work. The period after adoption is when users continue to use ICT and intended objectives can be accomplished. Therefore, this study investigated the process that the organizations adopting Smart Work have overcome spatial and temporal constraints and the performance that they have achieved after adopting it. Though the framework integrating time-geography theory with technology acceptance stage, this research interviewed four managers of three organizations being responsible for adopting and operating Smart Work and provided its adopting process and performance of each organization.

The use of a mobile agent in hospital environment offers an opportunity to deliver better services for patients and staffs. Furthermore, medical errors will be reduced because M-health system helps to verify the medical process. Optimized security protocols and mechanisms are employed for the high performance and security. Finally, a challenge in the near future will be converge the integration of Ubiquitous Sensor Network (USN) with security protocols for applying the hospital environment. We proposed secure authentication and protocol with Mobile Agent for ubiquitous sensor network under healthcare system surroundings.

The Many universities and educational institutions have focused on shifting education paradigm into smart learning using high-tech devices and internet as the level of technology has growing rapidly in every society. Especially, cyber universities and open universities in Korea are trying to develop educational network system and infrastructure corresponding to new convergence technology environment. Therefore, the purpose of this study is to introduce clouded based education system in order to suggest an effective way of using new educational learning system. This study shows the case of Hangout learning system used in K University in Korea to suggest a new educational learning model for real-time lecture and cloud based service platform for improving educational learning environment.

The purpose of this study is to make a lot of efforts for student employment in government or university. therefore We have developed Start-up Consulting courses that include easy to find jobs, convergence and multidisciplinary knowledge. The results of the comparison between university and graduate school, management consulting, and start-up consulting curriculum were reviewed according to STEAM 's rules. The results were divided into 5 main classes and 15 sub classes according to the 15 week subject. As a result of the study, we divided into 5 main classes and 15 sub classes in accordance with the 15 week subject. We were able to apply the understanding to the 1st stage company understanding(Arts), 2 stage consulting ability(Technology) 3 stage entrepreneurship strategy(Technology) 4 stage sub consulting(STEAM) 5 stage management case analysis(Arts).

The age of electric vehicle is coming. One of the most important problems to be solved for popularization of electric vehicle is fuel economy. To increase fuel economy of electric vehicles, it is necessary to improve the performance of the battery or the car body should be lighter than now. To solve the problem of the car body, change the car body's material to carbon fiber reinforced composites can be an excellent answer. However, the part made from carbon fiber reinforced composites is vulnerable to accidents due to their high brittleness. In this study, ductile silica fume was added into the carbon fiber composites to enhance toughness. To examine this, various amounts and sizes of silica fume were considered and the toughness enhancement was examined by performing tensile tests.
