This paper briefly reviews the history of the Korean geophysics and analyze the current status of geophysical researches. And the future prospects of geophysics are discussed based on social demands for the science and technology in Korea. About thirty universities offer geophysics courses in their academic curricula. Although the number of Ph.D. graduates in geophysics had been small until the year of 1990, but is rapidly increasing. In recent years about $7{\sim}8$ Ph.D's are produced every year. The major geophysical methods used in Ph.D. theses are seismic, electrical and electromagnetic methods, and earthquake waves and research themes are computational geophysics, which involve data processing, modelling, inversion and tomography, geological structures, and paleomagnetic studies in the order of numbers. The Solid Earth Geophysics is generally distinguished in two categories such as "Global Geophysics" and "Exploration Geophysics". However, they are intimately connected, and overlap in many sectors, especially in large scale research projects. The global geophysics has a more academic and general scientific meaning, and several research groups in Korean universities are carrying out the earthquake seismology and paleomagnetic studies. On the other hand the exploration geophysics focuses on practical application of geophysical concepts, and the public research institutes conduct large projects for exploration of energy and mineral resources and to cope with environmental and natural disaster problems. The geophysical studies for local geology and regional crustal structure utilize various survey methods and usually cover both academic and exploration purposes. The computational geophysics constitutes the indispensable theoretical backgrounds for all geophysical sectors. Many young Korean geophysicists, who have strong background in mathematics and physics, devote to the computational geophysics and several groups have made the internationally highest level achievements. But, Korean geophysicists have to expand their research interests to include more global-scale, high-tech researches and collaborative works with various other science groups.

The graduation project, which is the final results of the capstone design course, is not only the highest peak in university major education, but also criteria of the practical skills of fourth grader who is supposed to get a job in the future. Therefore, it is needed to operate a capstone design course that reflects industry requirements and its support system for cooperation with industry. In this study, we present a case of the capstone design course and the industry-academic capstone design program at the department of Information and Communication Engineering in Sungkyul University. At the time being transitioned from offline to online class due to COVID-19, we evaluate results of the capstone design class over the past three years and induce improvements for the further operation of the class. This study may contribute to be a practical reference for ICT-related departments that attempt to apply social demands in their capstone design course through industry-academic cooperation

The tollbooths of a main motorway toll plaza are usually operated proactively responding to the variations of traffic demands of two-type vehicles, i.e. cars and the other (heavy) vehicles, respectively. In this vein, it is one of key elements to forecast accurate traffic volumes for the two vehicle types in advanced tollgate operation. Unfortunately, it is not easy for existing univariate short-term prediction techniques to simultaneously generate the two-vehicle-type traffic demands in literature. These practical and academic backgrounds make it one of attractive research topics in Intelligent Transportation System (ITS) forecasting area to forecast the future traffic volumes of the two-type vehicles at an acceptable level of accuracy. In order to address the shortcomings of univariate short-term prediction techniques, a Multiple In-and-Out (MIO) forecasting model to simultaneously generate the two-type traffic volumes is introduced in this article. The MIO model based on a non-parametric approach is devised under the on-line access conditions of large-scale historical data. In a feasible test with actual data, the proposed model outperformed Kalman filtering, one of a widely-used univariate models, in terms of prediction accuracy in spite of multivariate prediction scheme.

Due to its cost effectiveness, tradeable emission permits (TEP) system has been effectively used in the USA and many other advanced countries. But, academic many researchers have been argued that TEP system would not work as an efficient regulatory tools when there are imperfect competition in permits and/or products markets. Sartzetakis (1997), however, show that TEP system can serve as an effective environmental regulation under the certain demand/cost conditions even though duopolistic production market is not competitive. In this paper we extend Sartzetakis's analysis into the differentiated products markets under the same cost conditions, and examine the relative efficiency of TEP system by comparing it with the command and control system. We then show that the main results of Sartzetakis can hold if two differentiated products markets have the symmetric demands. In particular, it is revealed that social welfare will be increased under TEP system even though consumer surplus may be decreased.

Third generation mobile radio systems (3G) are currently being deployed in different regions of the world. Future systems beyond 3G are already under discussion in international bodies and forums such as ITU, WWRF and R&D programs of the European Union and in other regions. These systems will determine the research and standardization activities in mobile and wireless communication in the next years. Based on the experience of 3G future systems will be developed mainly from the user perspective with respect to potential services and applications including traffic demands. Therefore, the Wireless World Research Forum (WWRF) was launched in 2001 as a global and open initiative of manufacturers, network operators, SMEs, R&D centers and the academic domain. WWRF is focused on the vision of such systems the Wireless World - and potential key technologies. This paper describes the international context of activities on systems beyond third generation, the goals, objectives and structure of WWRF, the user perspective as the starting point for a future system design and the key enabling technologies for the Wireless World.
