  • The cooperation between universities and industries is already one of the most important factors driving the national economy in the knowledge-based society of the 21st century represented by the Fourth Industrial Revolution. The Korean government has also been carrying out legal and institutional re-adjustments to promote industrial-university cooperation in line with demands for such changes in the times. However, despite this industry-academic cooperation system, there is still a significant mismatch between industrial demand and the university's workforce development system. By the way, there is a Cooperative Education(CO-OP) in Canada and the United States. It's an innovative link between the university and the industry. The reason is that the CO-OP program not only allows students to gain experience with their majors in the industrial field, but also plays a positive role in improving their specialty expertise. In particular, field information, ideas, and job insights that students acquire through CO-OP also serve as motivation for starting a business beyond employment after graduation. Furthermore, CO-OP experience is an important opportunity for future researchers to come up with commercialized research results that are not separated from the field sites The purpose of this study is to overcome the gap between industrial demand and the college manpower training system, and develop a Korean-style coaching program model as a growth engine for creative talent-building policies, represented by 'creation of start-ups and new industry.' In addition, this study suggested measures that can be applied in real universities. In addition, the study also highlighted that the introduction of CO-OP programs with field practices in Korea could also boost start-ups. Based on the Korean CO-OP program model, the curricula applicable to domestic universities consisted of two types : general and research-oriented university types.

  • Today, technique for precisely positioning vehicles is very important in C-ITS(Cooperative Intelligent Transport System), Self-Driving Car and other information technology relating to transportation. Though the most popular technology for vehicle positioning is the GPS, its accuracy is not reliable because of large delay caused by multipath effect, which is very bad for realtime traffic application. Therefore, in this paper, we proposed the Vision-Based High Accuracy Vehicle Positioning Technology. At the first step of proposed algorithm, the ROI is set up for road area and the vehicles detection. Then, center and four corners points of found vehicles on the road are determined. Lastly, these points are converted into aerial view map using homography matrix. By analyzing performance of algorithm, we find out that this technique has high accuracy with average error of result is less than about 20cm and the maximum value is not exceed 44.72cm. In addition, it is confirmed that the process of this algorithm is fast enough for real-time positioning at the $22-25_{FPS}$.

  • Community-based housing is widely recognized as one unique mode of affordable housing provision discussed in the agenda of urban housing policy in the midst of global economy. While economic development of rural communities are severely blocked by many factors, the local housing needs at grass roots level are addressed in the response to the growing number of the elderly and shortage of adequate housing to accommodate the group, and the availability of affordable housing is primarily seen as a viable option to the sustainability of rural community. This research study is to examine the case study of community-based housing development in rural areas, and to explore the drives and hurdles that influence the success of each development. The on-site visits and in-depth interviews with community leaders were employed to meet the research goals. The findings show that the driving factors making the successful housing development include the firm commitment to the importance of affordable and adequate housing, strong leadership of community leaders, public support, well-advised dispersion of public resources and strong bond between the public sector and local people. In spite of all the contributing factors, the unfamiliarity of collective ownership is the leading hurdle to proceed the development in a timely manner.

  • Recently, robotic automation in clinical laboratory becomes of keen interest as a fusion of bio and robotic technology. In this paper, we present a new robotic platform for clinical tests suitable for small or medium sized laboratories using mobile robots. The mobile robot called Mobile Agent is designed as transfer system of blood samples, reagents, microplates, and any instruments. Also, the developed mobile agent can perform diverse tests simultaneously based on its cooperative and distributed ability. The driving circuits for the mobile agent are embedded in the robot, and each mobile agent communicates with other agents by using Bluetooth communication. The RFID system is used to recognize patient information. Also, the magnetic hall sensor is embedded to remove and compensate the cumulated error of locomotion at the bottom of mobile agent. The proposed mobile agent can be easily used for various applications because it is designed to be compatible with general software development tools. The Mobile agents are manufactured, and feasibility of the robot and localization of the agents using magnetic hall sensor are validated by preliminary experiments.

  • This research worked on the cooperative case by Marc Jacobs, who was involved in innovative collaboration in the field of fashion, and the analysis on imbedded values. With assessment of it, this paper aims at providing the theoretical ground on prevalence of fashion collaboration for creative innovation and presenting the basic material in establishing the design and marketing in the fashion industry. In methodology, the review was followed up about literature regarding Marc Jacobs and collaboration and his cases in 2001 through 2012. Results showed that his collaboration cases could be divided into those with modern artist, those with fashion brand or designer, those with other field brand than fashion, and those with the public star. They were processed into such a form as development of new product and collection, shop display, and exhibition event. The value could be drawn from this case examination of Marc Jacobs' fashion collaboration, which includes the design innovation through reinterpretation of tradition, innovation of maximized brand value, and transboundary innovation toward a vast extension of realm. Namely, the collaboration of Marc Jacobs would be the driving force for design innovation and the creative process for both parties concerned through endless cooperation and would generate the innovative value for fashion field.

  • Overhead sign support structures number in the tens of thousands throughout the trunk-line roadways in the United States. A recent two-phase study sponsored by the National Cooperative Highway Research Program resulted in the most significant changes to the AASHTO design specifications for sign support structures to date. The driving factor for these substantial changes was fatigue related cracks and some recent failures. This paper presents the method and results of a subsequent study sponsored by the Michigan Department of Transportation (MDOT) to develop a relative performance-based procedure to rank overhead sign support structures around the United States based on a linear combination of their expected fatigue life and an approximate measure of cost. This was accomplished by coupling a random vibrations approach with six degree-of-freedom linear dynamic models for fatigue life estimation. Approximate cost was modeled as the product of the steel weight and a constructability factor. An objective function was developed and used to rank selected steel sign support structures from around the country with the goal of maximizing the objective function. Although a purely relative approach, the ranking procedure was found to be efficient and provided the decision support necessary to MDOT.

  • VANET(Vehicular Ad-hoc Network) is a kind of ad hoc networks which is consist of intelligence vehicular ad nodes, and has become a hot emerging research project in many fields. It provides traffic safety, cooperative driving and etc. but has also some security problems that can be occurred in general ad hoc networks. In VANET, it has been studies that group signature method for user privacy. However, among a group of group key generation phase and group key update phase, RSU(Road-Side Unit) and the computational overhead of the vehicle occur. In this paper, we propose an efficient group key management techniques with CBF(Counting Bloom Filter). Our group key management method is reduced to the computational overhead of RSU and vehicles at the group key generation and renewal stage. In addition, our method is a technique to update group key itself.

  • VANET(Vehicle Ad-hoc Network)은 통신 기능을 지원하는 지능형 차량들로 이루어진 애드혹 네트워크 환경으로써 최근 들어서 그 연구가 매우 활발하게 진행되고 있는 분야이다. VANET은 원활한 교통 소통, 사고 방지 등 여러 가지 편리한 기능들을 제공하지만, 그 기반을 애드혹 네트워크에 두고 있기 때문에 애드혹 네트워크에서 발생할 수 있는 보안 문제가 그대로 발생하며, 또한 그 환경적 특성에 따라 추가적인 보안 요구사항 역시 존재한다. VANET 환경에서 가장 중요하게 요구되는 보안요소는 협력 운전(cooperative driving) 시 메시지 인증, 무결성, 부인방지 등과 특정 차량에 대한 추적을 할 수 없도록 하는 위치 프라이버시 보호이다. 그러나 이 가운데 사용자의 위치 프라이버시는 조건적으로 신뢰기관에 의한 추적 역시 가능해야 한다는 조건을 포함한다. 본 논문에서는 L. Martucci 등이 제안한 자체적으로 생성하고 인증하는 pseudonym 기법[1]을 이용하여 이러한 보안 요구사항들을 만족시키는 방법을 제안하고자 한다. 제안하는 기법은 최초 차량 등록 시 받은 비밀 인자를 이용하여 보안 통신을 하며 추가적으로 신뢰 기관으로의 통신이 필요하지 않는 효율적인 보안 기법이다. 또한 기존 연구에서 발생했던 저장 공간의 문제, RSU(Road Side Unit) 접근 문제 등을 해결한다.
