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.

국내 대부분 대학에서는 졸업작품을 제작하기 위해 '종합설계'와 같은 캡스톤디자인 교과목을 운영하고 있다. 캡스톤디자인의 산출물인 졸업작품은 대학 전공 교육과정의 최고 결정체인 동시에, 앞으로 취업할 4학년 학생들의 실무능력을 가늠하는 척도이기도 하다. 따라서 대학에서는 산업체 요구사항을 적절히 반영한 캡스톤디자인 교과목 운영과 산학협력을 위한 지원체계가 필요하다. 본 연구에서는 성결대학교 정보통신공학과에서 운영되는 캡스톤디자인 교과과정과 이를 지원하는 산학협력 캡스톤디자인 프로그램 운영사례를 소개한다. 코로나19로 인한 비대면에서 대면 수업으로 전환한 현시점에서, 최근 3년간 '종합설계' 교과목의 평가 결과를 분석해 보고, 추후 캡스톤디자인 교과목 운영을 위한 개선방안을 도출한다. 이 연구는 산학협력을 통해 사회적 요구를 캡스톤디자인 운영에 반영하려는 ICT관련 학과에 참고할 만한 사례가 될 것으로 기대된다.

고속도로의 주요 영업소 톨부스는 일반적으로 2개 차종(경차포함 승용차, 승용차 이외의 중차량)의 교통수요 변동에 따른 사전 대응방식으로 각 차종에 대하여 운영된다. 이러한 의미에서 2개 차종에 대한 정확한 교통량 예측은 영업소의 첨단 운영에 있어 주요 요소 중 하나이다. 유감스럽게도, 기존 연구로 보고된 현행의 일변량 단기 예측 기법들을 이용하여 2개 차종의 교통량을 동시에 예측하기는 용이하지 않다. 이러한 실용적 학술적 배경으로 인해 수용 가능한 정확도의 수준에서 2개 차종의 장래 교통량 예측은 ITS 예측 분야의 매력적인 연구 주제 중 하나이다. 따라서 본 연구에서는 기존의 일변량 단기 예측기법의 단점을 극복함과 더불어 2개 차종의 교통량을 동시에 예측하기 위한 다중 입출력(Multiple In-and-Out, MIO) 모형을 제시하도록 한다. 제안된 MIO 모형은 대용량 이력자료의 실시간 이용이 가능한 자료 환경에서 비모수 접근법을 기반으로 개발되었다. 실제 자료를 이용한 적용가능 실험에서, 개발모형은 다변량 예측 수준에도 불구하고 폭 넓게 이용되는 일변량 예측모형 중 하나인 Kalman filtering에 비하여 예측 정확도 측면에서 우수하게 나타났다.

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.

Participant observations, in-depth interviews, and analyses of documents were used for collecting data. Children separated from their parents were living with grandparents because their parents were working abroad. Results included socio-cultural and psycho-social factors. (1) The socio-cultural grounded factors or the common characteristics of young children's family life in both living circumstances included early childhood academic achievement orientation, demands of responsibility and obedience, limited opportunity for social development, and societal phenomenadeveloping wide family concept affected by China's Confucianism and Korean-Chinese social culture. (2) Psycho-social grounded factors included the present care-givers' perceptions of the child's agency and their beliefs in the importance of play and friendship. This affected interactions between child and care-giversand child's self-esteem and friendships.

Purpose: Regarding workers' health promotion and disease prevention, the law on the health management system has been enacted and implemented since 1961. However, regulations related to health managers do not meet recent demands for changes in fields such as industrial structure, occupational health problems, or the improvement of occupational health skills. This study aimed to suggest improvement strategies regarding the health management system in the workplace. Methods: We summarized past empirical or theoretical literature. Results: This study summarized the overview and history of the Korean occupational health management system, advanced foreign occupational health management system, and the effectiveness of the health management at workplace. Further, this study proposed various strategies to improve the occupational health management system in Korea. Method: We summarized past empirical or theoretical literature. Conclusion: The effective operation of the health management system in the workplace would improve workers' health, in addition to enhancing national competitiveness through securing a healthy workforce.

빠른 경제 성장으로 인하여 대학은 교육의 질적인 면보다는 많은 수의 졸업생을 배출하는 데만 집중해왔다. 그러나 정보화사회가 도래하면서 대학 졸업생들은 다양한 문제를 해결할 수 있는 능력을 갖추도록 요구되고 있다. 또한 정보기술이 발전할수록 해결해야 할 문제들이 점점 더 복잡해지고 있다. 본 논문에서는 산업체와 학계의 정보기술 전문가들과 인터뷰를 통하여 기존의 정보기술 교과과정을 분석하였다. 그리고 현업에 종사하고 있는 졸업생들의 역할에 기반을 두고 인터넷정보과에 적합한 새로운 교과과정을 제시하였다.
