Currently, attempts are being made to introduce innovative teaching methods in architectural engineering education. However, there is still a lack of research supporting self-directed learners. In this regard, this study sought to develop an application prototype to support learning from online lectures on architectural engineering and conduct prototyping for its evolution. Menus in the application prototype consisted of four main categories: lecture operation, video lectures, eBooks and past exam questions. The lecture operation was classified into eight sub-categories, including assignment submission and notice, so as to support interactions between instructors and learners as well as confirmation of the delivery methods. With respect to video lectures, assignment submissions and notice functions, prototyping connecting the mobile web was implemented to enhance user convenience.

Cloud computing has evolved significantly, intending to provide users with fast, dependable, and low-cost services. With its development, malicious users have become increasingly capable of attacking both its internal and external security. To ensure the security of cloud services, encryption, authorization, firewalls, and intrusion detection systems have been employed. However, these single monitoring agents, are complex, time-consuming, and they do not detect ransomware and zero-day vulnerabilities on their own. An innovative Record and Replay-based hybrid Honeynet (R2NET) system has been developed to address this issue. Combining honeynet with Record and Replay (RR) technology, the system allows fine-grained analysis by delaying time-consuming analysis to the replay step. In addition, a machine learning algorithm is utilized to cluster the logs of attackers and store them in a database. So, the accessing time for analyzing the attack may be reduced which in turn increases the efficiency of the proposed framework. The R2NET framework is compared with existing methods such as EEHH net, HoneyDoc, Honeynet system, and AHDS. The proposed system achieves 7.60%, 9.78%%, 18.47%, and 31.52% more accuracy than EEHH net, HoneyDoc, Honeynet system, and AHDS methods.

The purpose of this study is to research the women engineers' recognition with a triangulation method and make suggestions on desirable education in engineering. The research period is for about 4 months from December 15, 2007 to April 4, 2008. The objects of the research are two groups of female engineers at D college located in the metropolitan area - the first group had 187 women engineering majors, 3 women graduate students and 2 women professors in engineering department, and the second group had 5 women engineering majors who once stayed out of school temporarily, 4 women engineering graduates, and 5 graduates who are currently working. The second group is intently selected in order to look into the detailed factors that affect the recognition of women engineers. The methods of the research varied and included were surveys on the web, personal interviews, focus meetings, surveys by e-mail and telephone, etc. The results of the study show what the women engineers want in engineering education includes to have role models of women engineers who can cast a vision to them, get a leadership training especially for when they lead a group that has both man and woman members. It was also found that experincing a cooperative learning through diverse projects is essential to build basic character training and competency, and practical education is required for the major or becoming a full time worker.

Globally, the change in higher education is gradually moving toward a trend that seeks a change in innovative higher education through the revitalization of digital-based education. Accordingly, this study designed a customized education model based on e-learning that can be used in undergraduate education and development of lifelong vocational skills. The use of online learning platforms and the expansion of education are major factors that change the overall higher education system as the form and content of curriculum changes around the world. In order to establish a customized education model using online learning platform, this study analyzed major overseas advanced education cases and selected the basic direction of customized learning as personalized learning, competency based learning, and training for talents leading the 4th Industrial Revolution. Then, FGI was conducted for undergraduate and lifelong vocational ability development experts. As a result, a customized education model using an online learning platform was derived from a degree-type model available in undergraduate education and a non-degree-type model available in the field of lifelong vocational ability development, and each operation strategy was suggested.

This study aims to provide an industry-university cooperation cap in a non-face-to-face environment so that sharing and cooperation between universities can be shared based on the advanced digital technology between various universities at a time when it is rapidly changing to an online mode. It is in developing the stone design course. To this end, we analyzed the literature and previous studies on non-face-to-face environments and capstone design, developed a model for industrial-educational collaboration-type capstone design subjects in non-face-to-face environments, and suggested an application plan. The wearable capstone design program was pilot-applied, and the effectiveness was confirmed and corrected through the students' interview and questionnaire. This can be used as an industrial-educational cooperation engineering class capstone design class plan, providing basic data for development and operation, and as a step-by-step operation guide in a non-face-to-face environment.

This thesis is for understanding what women engineer need educational support through the research of motivation when women engineer apply 'engineering college', choosing their major and also, self-efficacy. We collect data through 108 people University of K students and 104 students in D University both of them are located in metropolitan area. In the same way, research 101 students who are attending National university C in Chungchung-do, 104 students in Keungsang-do national university of C and 119 students of J National university belonging in Jeju-do whole number is 536. The questionnaire has corrected and supplied through the Doctor Kim thesis(2004) by two doctors of education. The questionnaire has 5 questions for motivation and 26 questions for self-efficacy and we started research from Sep. 1. until Sep. 26. in 2008. As the result of research, firstly the students who have aptitude for engineering or engineering major show more understanding, less give up when they against difficulty, more talent for studying than the students without aptitude. Secondly the students who decide to apply 'engineering college' before taking entrance examination can compare with the students who decide after taking test. Consequently, already decided before taking test students have more higher self-efficacy.

In this research, we analyzed the effects of the independent research program on the educational experience of undergraduate students in a research-centered university setting. The independent research program was developed to provide undergraduate students with opportunities to engage in self(student)-initiated, self-regulated and self-responsible research projects. We hypothesized that outcomes of the program would be utilized as a baseline information in formulating the strategies for improvement of the undergraduate curriculum. Eighty three undergraduate students participated in the program during the period of 2003-2009. In order to evaluate results of the program, we carried out survey and in-depth interviews with the participants. According to the participant reports, the independent research program has helped them to develop self-managed research abilities and problem solving skills. They also indicate that the program has offered them the opportunities to survey the various major fields transcending different domains, so as to help them to contemplate on their future career choices. We suggest that such information may provide an essential guideline for developing an innovative undergraduate curriculum.

Functionally gradient material (FGM) is promisingly effective in mitigating the thermal stress between plasma facing materials (PFM) and structural materials. However, the corresponding research with respect to W/V FGM has not been reported yet. In this work, we firstly report the successful fabrication of W/V FGM by a combined technology of mechanical alloying (MA) and spark plasma sintering (SPS). The microhardness and microstructure of the consolidated sample were both investigated. W/V stacks show significantly enhanced microhardness (>100%) compared with pure W plate, which is beneficial to the integral strength of the hybrid structure. Furthermore, we clarify that the different ductility of W and V should be carefully considered, otherwise W/V powder might aggregate and lead to the formation of compositional segregation, and simultaneously unmask the impact of V proportion on the distribution of second phase in W-V binary alloy system. This work provides an innovative approach for obtaining W-V connections with much better performance.
