KOSEN, which emphasizes the acquisition of practical skills from the age of 15, is a good fit with the Cyber security body of knowledge. A cyber security education proj ect has occurred at KOSEN, and a project to develop cyber security teaching materials for further teacher training is also underway. In the course of examining the learning effectiveness in this project, we obtained the knowledge that a certain amount of motivation is a critical point to improve the learning effectiveness when using our teaching materials, when cyber security education is viewed from the perspective of gamification. In this study, to make this finding even more effective, we attempted to confirm whether or not Game Based Learning (GBL) enhances motivation and improves learning effectiveness, both in our teaching materials and in teaching materials developed by others, and to gain a foothold for examining the details of the effectiveness of GBL. The validation results show that prior learning in our materials, whether developed by us or not, works effectively in subsequent learning with materials, increasing motivation and positively correlating learning effects with motivation. As a next step, we will obtain further directions for future educational development by further examining which elements contributed to motivation and which were influenced by motivation.

As cyber-attacks intensify, cyber security education in engineering education is becoming increasingly important, and KOSEN, which emphasizes the acquisition of practical skills from the age of 15, is a good fit with the cyber security body of knowledge. The cyber security education project has occurred at KOSEN, and a project to develop cyber security educational materials that also serve as teacher training has been carried out for the past several years, and the educational effects of the developed educational materials have been examined. Educational methods using educational materials can be expected to improve some skills. However, when cyber security education is viewed from the perspective of gamification, motivation for the concepts of attack and defense may contribute to educational effectiveness. In this study, we discussed the motivation that contributes to the effectiveness of skill improvement in practical exercises using educational materials developed through the project we have been working on. We also discussed whether it is possible to enhance life-work balance by considering the project itself as a Role Playing Game, and obtained suggestions on the effectiveness of motivation and how the project can enhance life-work balance.

Cyber-attacks are on the rise, and the advent of COVID-19 has changed work styles, leading to an increase in cyber-attacks targeting remote workers. This situation is the same in the world and in Japan, and the development of cyber security personnel and their training to face the attackers who can respond to the social situation is desired all over the world. The National Institute of Technology (KOSEN) is known not only in Japan but also in the world as the only institution of higher learning in the world where students can freely study engineering for five years from the age of 15. The technical framework of cybersecurity and the KOSEN education, which is based on the acquisition of practical skills, go hand in hand, and KOSEN is an important higher education institution that plays a part in the cybersecurity human resource development strategy in Japan. In 2015, KOSEN launched the KOSEN Security Educational Community (K-SEC) to initiate cybersecurity education for KOSEN students. This project has two objectives: one is to develop excellent cyber security personnel for qualitative improvement. The second is to develop a large number of KOSEN students who have systematically acquired security knowledge for the purpose of quantitative expansion. In 2019, a new project, Highly Advanced Cybersecurity for KOSEN (HACK), was launched within K-SEC to accelerate the achievement of the two objectives of K-SEC. HACK is a project based on a simple idea: to strengthen KOSEN faculty in order to develop strong students with practical cybersecurity skills. Participating faculty members will develop cyber range materials. The development of the cyber range will contribute to the understanding of both attacker and defender scenarios and the acquisition of advanced security knowledge and skills. In the previous paper, we reported on the results of the first year of HACK (2019). The faculty development plan, which mainly focused on cyber range development, contributed to the motivation and skill development of the faculty. The cyber range as a deliverable was also obtained. This paper reports on the outcomes of the second year (2020) of HACK activities. Within the faculty development plan, which mainly focused on cyber range development as in the first year, we used the deliverables of the first year to give lectures to KOSEN students to measure the educational effects. During the cyber range development, there were some knowledge and skills that the faculty intended to have the KOSEN students improve their skills. Therefore, the focus of the study was to see if the faculty members’ intended skills would be improved when they gave lectures to the KOSEN students using the teaching materials. As it turned out, we were able to achieve this goal, and we were able to improve the skills of the KOSEN students as intended by the faculty. Furthermore, it was not only possible to control the skills to be improved by the content of the teaching materials, but also by the way the lectures were delivered. In addition, by selecting the theme of the cyber range development, we were able to achieve the intended skill improvement for the faculty. Through the implementation of HACK until the second year, we were able to identify many factors for skill improvement. In the third and fourth years of the program, we will continue to look for factors that can be used to further improve specific skills, and at the same time, we will explore the relationship with motivation, which is expected to contribute greatly to educational effectiveness.

Threats of cyber attacks are rampant all over the world. The threats are getting stronger year by year. In 2015, the National Institute of Technology (KOSEN) launched the KOSEN Security Educational Community (K-SEC) and started cyber security training for KOSEN students. This project has two main purposes that one is outstanding cyber security human resource development which objects for improving quality and other one is fostering many KOSEN students who have systematically acquired security knowledge which objects for quantitative expansion. As part of K-SEC, research of cyber security human resource development education has been promoted. A new project ”Highly Advanced Cybersecurity for KOSEN (HACK) ” has been launched within K-SEC to accelerate the achievement of the two main purposes since 2019. HACK is a project based on the simple idea of strengthening KOSEN technical staff in order to foster strong students who have acquired practical cyber security skills. The plan is a three-year plan. HACK has three main objectives which are improving faculties ' and technical staffs' skills, the development excellent teaching materials based on the skills and to create both skills and human resources network. The success of HACK is important to contribute not only to security education but also to the examination of KOSEN or engineering education centered on practical education. In this paper, we will evaluate the effectiveness and legal theory of cyber security practice education for faculty and technical staff who participate the IT course in the first year. In addition, we will verify the effect of improving the skills of each faculty member in the off-season until the start of the second year. Furthermore, we will also consider whether the cyber security skills of the entire technical college have improved in the fiscal year. This year, we are proceeding with the project for the second year. In the second year, based on the results of the first year, we will evaluate, consider and examine for the improvement of the educational content toward the third year, which is the completion year. The evaluation includes the validity of the schedule. We also achieved a certain level of success in the development of teaching materials. This project is in good condition for the continuation of the plan and consideration of new items for the next year and after next year. In this paper, we report on the process of building this sustainable and effective cybersecurity education methodology suitable for KOSEN faculty and staff, and thus for students.

Automated interference detection is required for operation and management services in wireless networks as Wireless Local Area Networks (WLANs) based on IEEE 802.11 Standard since co-channel interference from other wireless transmitters occurs irregularly. We propose a new approach for detecting the presence of interference on 802.11 links. Our solution focuses on the Access Point (AP)-initiated monitoring approach without Wireless Station (STA)-initiated additional function and sniffer devices. Our approach uses the geographical distribution of the response delay of the Acknowledgment packet (ACK) to the downlink packet that AP transmitted to STAs. The proposed method consists of a continuous monitoring step and a periodical diagnosis step to measure network statistics by ACK response delay between an AP and STAs and to detect whether and where interference occurs respectively. Comprehensive simulation results show that the proposed approach has a good accuracy and low misdetection ratio for diagnosing the interference existence and location in IEEE 802.11 WLANs.

We have developed a KANSEI (feeling or sensitivity in Japanese) dictionary system applicable to the semantic network by making use of the similarity of each word. This dictionary system can construct the numerical value of KANSEI words each of which is quite ambiguous. We introduce KANSEI words into our current information systems that manage subjective information. This dictionary handles more than 800 KANSEI words, the contents of which suffice for general purposes.
