I report here about the future direction of cooperation of astronomy in East Asia region, which has been a long-years subject of the EAMA since 1990. During this EAMA-6 we had many positive discussions and remarkable progress toward the promotion of our cooperation. We also had an 'East Asian Observatory' WG meeting yesterday with many attendants, and actively discussed this important subject in some detail. The following report is to summarize the fruitful products we had in the EAMA-6 discussions and in past EAMA activities, and to propose a direction and some action items toward the bright future of astronomy in East Asia.

Nowadays, The function of telecommunication contributes to maintaining the peace of the world, and the international cooperation in the communication field can not be emphasized too much. The pioneers in telecommunication field dvoted their lives to the infinite love for humanity. However, the modern communication system in our country was initiated, in the later part of the Lee-Dynasty, not for the international cooperation but for the invasive avarices of the neighbouring nations such as Japan and China. The true international cooperation should be based on the love of humanity and the peace of the world such as the pioneers'. This paper proposes to resarch the historic process of initiation and development of the international organs relating to telecommunication as well as the international telecommunication network. Finally, I will make the following suggestions for the promotive direction of the true international cooperation. 1. Intensification of the radio administrative power. 2. Promotion of the international cooperation on the man-power and economy in telecommunication field. 3. Establishment and adjustment of research institutes of telecommunication. 4. Promotion of space communications. 5. Establishment of the world telecommunication network for world-wide peace.

This study aims to present the future direction of smart city in Korea through the review of smart city governance. first of all, reviewed the trend of smart city governance. Since then, Establishing direction of korea Smart City governance based on the implications. Finally, derive a field where cooperation between ministries and agencies is possible, and presented a cooperation scheme accompanying it. The results of this study are expected to provide a foundation to link smart city projects efficiently and contribute to the activation of smart city policies and projects.

Nowadays , The function of telecommunication contributes to maintaining the peace of the world, and the internetional cooperation in the communication field can not be emphasized too much. The pioneers in telecommunication field devoted their lives to the Infinite love for humanity.

The technology of direction finding is very important to find the direction of emitters for ELINT(electronic intelligence) system. The principle of TDOA(time difference of arrival) is to receive an emitter signal with two antennas, measure the time difference between two antennas, and converse the time difference to direction difference. This technology can be used in broadband frequency system and make the system very simple because a phase-discriminator and a voltage comparator are not needed. For fine DF accuracy, high time resolution receiver and long basis line antennas are needed. The DF accuracy of noise added signals is simulated with different time

This research is the comparative analysis of Jim Hall's master work "Careful" and "Waltz New" who is the most influential guitar player of the present day. I tried to analysis musical inclination and direction comparison with contemporary musicians in this study. Jim Hall wasn't the person who did satisfy with only playing guitar as a famous artist but trying to research and create a new thing continuously with this his music. I am considering that his music has been great implications for contemporary direction.

Fifteen years have passed since the enactment of the Industrial Technology Innovation Promotion Act, which promoted industry cooperation activities for universities. Therefore, the study analyzes the relationship between the university's industrial cooperation activities and the college graduates' starting salaries and provides policy suggestions on improving the direction of university-industry cooperation. The study used nine-year panel data from Graduates Occupational Mobility Survey (GOMS) to conduct an empirical analysis and found that starting salaries of college graduates were not significantly higher if the university only participated in basic industry cooperation activities. On the other hand, when the quality of university-industry cooperation activities was higher, such as job search support, the starting salary of college graduates was higher. The findings suggest that university-industry cooperation activities must focus on qualitative performances rather than quantitative approaches.

The direction finder is an important device for an electronic support(ES) system because it is responsible for finding the direction of an emitter. The higher the accuracy of the direction finding, the higher the vitality of the weapon system with the ES system. Recently, the direction error occurred in the operating shipboard ES system when direction finding was performed for the signal with a pulse width of 200 ns. Therefore, this paper proposes, an improved method to reduce the direction error for shipboard ES systems. The proposed method was applied to the operating shipboard ES system and a field test was performed. The results of the field test showed that the direction error was reduced significantly for the signal with a pulse width of 200 ns.

TThe cooperation on disaster prevention between the two Koreas has been mostly focused on cooperation at the recovery stage, such as emergency relief supplies and equipment support. This study aims to articulate future practical development plans by analyzing disaster cooperation between North and South Korea in accordance with the changing paradigm of international disaster cooperation. Considering the specificity of inter-Korean cooperation, the Framework for Inter-Korean Disaster Prevention Cooperation was established centering on the Sendai Framework for Disaster Risk Reduction. The framework consists of understanding and sharing disaster risks, building back better, strengthening community resilience, and supporting regional disaster action plans for continuous action. Inter-Korean disaster prevention cooperation requires sharing information about North Korean disasters. It is necessary to accurately identify and support social vulnerability to North Korean disasters. Above all, it is supporting the development of disaster action plans from a humanitarian perspective needs. A medium-to-long term resilience reinforcement plan that North Korea can resolve on its own is also needed. Since North Korea is also deeply interested in international disaster cooperation, it should be based on the direction of the Sendai Framework. Considering the uniqueness of inter-Korean cooperation, a path for North Korea to actively participate in international disaster cooperation should be established.

A direction finding(DF) technology of a signal is very important for electronic warfare and has studied for a long time. The method of TDOA(time difference of arrival) is one of good DF methods in this time, and that is to receive an emitter signal with two antennas, to measure the time difference of a signal at two antennas, and converse the time difference to direction of the signal. For small DF error, high time resolution receiver and long baseline are needed. In this paper we suggest a good baseline with adaptive antenna arrangement into 10m*10m area.
