Current design-build contract is the type of joint venture, but performs by separate party which causes change orders due to the lack of communication between design and construction, so it cannot lead the main object which is the integration of design and construction. Furthermore, the current design-build contract is impossible to reduce the project costs by VE at the design development phase because the design proceeds with the fixed price through bidding. Like these limitless, the analysis results of the case of VE in the design-build projects, several problems that are prevented from active design VE are elicited by the project participants. Meanwhile, Ministry of Construction & Transportation decided to enlarge the VE review system lately. Therefore, in this study, it presented model of design VE partnering of design-build and partnering agreements form to apply design VE and to try to be able to lead the design VE to be more successful in public design-build projects.

The current design paradigm shift which has been in progress around the world would be a good opportunity for Korea, which has led the age of information, to build design competence and gain international competitiveness. In addition, it would be a good idea for colleges as well as firms to develop a new educational system and create academia-industry-research synergy. This paper researches the market KU project promoted by Design Venture KU which has been established by the College of Artand Design of Konkuk University as a part of differentiation strategy. The methods to improve the competitiveness of Korean fashion design by uniting college creativity and market practicality are as follows: First, for convergence of creativity and practicality, it is necessary to come up with a systematic design-based educational system. In other words, the undergraduate program needs to gradually expand courses by focusing on creativity instead of functions while the graduate program should be able to develop design pattern, textile and marketing products and secure the market to gain competitiveness as a business incubator. Second, the working-level engineers as well as professors will be encouraged to participate in special lectures or seminars and take necessary lessons. In addition, academia-industry cooperation courses will be further strengthened. It is also important to actively participate in an official contest or exhibition and receive a prize. Third, to elicit creativity from students, it is necessary to help them think in a flexible and experimental way with voluntary and interesting programs. As mentioned above, it is expected that 'Market KU Project' would help students build expertise by offering them a chance to experience the real world and become the world's leading designers in Korean fashion design.

The purpose of this study is to explore to determine the maximum volume with doing permanent waving in flat crown of the head. The method was like this. First of all, the diameter, the ratio of the circumference of a circle to its diameter and the number of rotations were analyzed same hair using permanent waving rods each number of 1$\sim$10. Secondly, the increasing rate of volume of curls number of 1$\sim$10 was analyzed. According to the result of the experiment, as the number of permanent waving rods were bigger, the ratio of the circumference of a circle to its diameter constant was increasing but the number of rotations was decreased. When the permanent waving rods of each number 1-3(Big diameter) were used, the volume was decreased. That's because there was fewer rotation compared to the diameter and was no ample combed dried hair. Due to this kind of reason, there was no perfect curling. Once number 10 permanent waving rods (most small size) was used, the shape of curling was strong and the stability was made after combed dried hair. But volume was decreased by 9% because of the cohesive power. In case of number of 4$\sim$9 rods used, volume was increased. Volume was highest when permanent waving rods was number 5 which was used combing on base both morphology and numerical value.

In the public certificate technology commonly used in Korea, users have a cumbersome problem of always resetting when they forget their password. In this paper, as a solution to this problem, we propose a secure authentication certificate password recovery protocol using blockchain, PKI, and DID for distributed storage. DID is a schema for protecting block ID in blockchain system. The private key used in the PKI is configured as a user's biometric, for example, a fingerprint, so that it can completely replace the memory of the complex private key. To this end, based on the FIDO authentication technology that most users currently use on their smartphones, the process of authenticating a user to access data inside the block minimizes the risk of an attacker taking over the data.
