In a study of the existing Collaboration, U-I Collaboration linkage(LINK) has a width of the various channels through continuous mutual cooperation by the path-dependency. U-I Collaboration linkage(LINK) through the various channels is more powerful, whereas this increase trade-related barriers. In other words, It has been discussed in many literatures about the U-I Collaboration linkage(LINK). However, relatively a study on the factor of the barrier about U-I Collaboration linkage(LINK) is a minority. Given the importance of policies to establish an association of industry-university cooperation and support system, the lack of research on the obstacles to U-I Collaboration linkage(LINK) will be a serious obstacle for designing effective policies. This paper examines the existing literature about the width of mutual cooperation and the barrier of U-I Collaboration, analyze to lower the barrier of U-I cooperation through POB(Positive Organization Behavior) of university administration. In conclusion, we would like to suggest the policy implications.

If the correct structure of Web site is known, the information provider can discover users# behavior patterns and characteristics for better services, and users can find useful information easily and exactly. There may be some difficulties, however, to extract the exact structure of Web site because documents one the Web tend to be changed frequently. This paper proposes new method for extracting such Web structure automatically. The method consists of two phases. The first phase extracts the hyperlinks among Web documents, and then constructs a directed graph to represent the structure of Web site. It has limitations, however, to discover the hyperlinks in Flash and Java Applet. The second phase is to find such hidden hyperlinks by using Web access log. It fist extracts the click streams from the access log, and then extract the hidden hyperlinks by comparing with the directed graph. Several experiments have been conducted to evaluate the proposed method.

In this paper, a minimum rotation radius was designed and fabricated to overcome the threshold so that elderly or disabled people who have difficulty moving can move and transfer safely and conveniently in a narrow room. In the indoor environment, where the sedentary culture develops, this study aimed to provide convenience for passengers with fracture diseases, geriatric diseases, and other knee and waist diseases. First, links, seats, armrests, covers, motors, batteries, chargers, controllers, etc. were attached to the frame so that they could be moved and lifted indoors. The product design and structure were designed considering the user's environment and physical characteristics, and IoT functions were added. A driving experiment was performed to confirm the operating performance of the manufactured indoor moving and lifting wheelchair. The performance tests, such as continuous running time, turning radius, maximum actuator load, maximum lift height, sound pressure level, minimum sensing distance of the driving aid sensor, interworking of server and app programs, device compatibility, and duty cycle error rate, were performed. As a result of the test, the built-in wheelchair could achieve the performance test target of each item and operate successfully.
