지금까지 국내 연구자들이 SCI 학술지에 발표한 의학논문의 수가 아주 미미하기 때문에 전 세계 학자들이 발표한 SCI 전체논문 중 한국논문이 차지하는 비중은 지극히 낮은 것으로 보인다. 따라서, 본 연구에서는 1980년부터 1990년 사이에 국내에 있는 의학 관련기관의 연구자들이 SCI 학술지에 발표한 논문이 SCI 전체 논문 중 차지하는 비중(Percentage Contribution from Korea to SCI Database)을 47개 의학분야별로 조사하였다. 또한. 본 연구에서는 "국제적으로 영향력 있는 학술연구 활동실적(i.e., Mainstream Productivity)"이 타 분야보다 뛰어난 한국의 의학분야를 밝히기 위하여. SCI 학술지에 발표된 모든 한국 의학논문 중 한 분야의 논문이 자치하는 몫(Percentage Share)을 SCI 전체 논문 중 그 분야의 논문이 차지하는 몫으로 나누어 그 상대적 크기를 분석함으로써, 우리나라 학자들의 Mainstream Productivity Ratio(R)를 각 분야별로 측정하였다. (R=1은 SCI 의학 학술지에 발표된 모든 논문 중에서 어떤한 분야의 논문이 차지하는 비율만큼 한국에서도 그 분야의 논문이 SCI 학술지에 투고되었다는 의미이다.) 1980년에서 1990년 사이에 한국 학자들에 의하여 SCI에 발표된 의학논문이 SCI 전체 의학논문 중에서 차지하는 비율은 $0.051\%$였다. 각 의학 분야별로는, Biotechnology & applied microbiology의 기여도가 $0.8\%$를 차지하여 한국 최고를 기록하였다. 전 세계 문헌의 $1\%$ 이상을 생산한 의학 분야는 없었다. 전 세계 문헌의 $0.1\%$ 이상을 SCI 학술지에 게재한 의학분야는 47개 중 6개인데, 위에 언급한 Biotechnology & applied microbiology를 제외하면 $0.1\%$에서 $0.2\%$ 사이의 기여도를 보였다. 최다 편수의 논문을 낸 Pharmacology 8l Pharmacy$(0.075\%)$나 두 번째로 논문수가 많았던 Biochemisty & molecular biology$(0.054\%)$의 기여도는 $0.1\%$에 미치지 못하였다. 조사대상이 된 47개 의학분야 중 27개 분야에서 예상된 것보다 상대적으로 적은수(R<1)의 한국 논문이 SCI 학술지에 게재되었다. Mainstream Productivity Ratio가 3보다 큰 분야는 4개인데, 그 중 Biotechnology & applied microbiology는 R=15.63으로 아주 월등한 논문 발표실적을 올렸다. Dermatology & venereal diseases(3.02)와 Engineering, biomedical(3.75)도 국제적으로 영향력 있는 학술지에 논문 발표실적이 뛰어난 의학분야이다.

In this paper, 3D input and output systems for a web-based real-time 3D video communication system using IEEE 1394 digital cameras, Intel Xeon Server system and Microsoft Directshow library is proposed. And some conditions for optimizing the operations of the stereo camera, 3D display and signal processing system are analyzed. Input & output systems are carefully selected, which can satisfy the required optimization conditions and the final 3D video communication system is implemented by using three optimized devices. The overall control system is developed with Microsoft Visual C++.Net and Microsoft DirectX 9.1 SDK. Some experimental results show that the observer can feel the natural presence from multi-view(4-view) 3D video of server system in real-time and also can feel the natural presence from 3D video of client system and finally suggest an application possibility of the proposed web-based real-time 3D video communication in real fields.

Animation contents are gradually growing every year, but production period and budget for making one animation contents is insufficient as of now. In particular, in case of animation series that are broadcasted on television, many episodes should be made within a short period of production term. Hence, production pipeline of full three-dimensional animation is frequently chosen in this case. However, another problem emerges as the full three-dimensional animation also requires a lot of time for making high-quality background and for rendering. Composed animation is a production pipeline that attempts to solve such problem. It is a pipeline of producing animation by composing computer graphic (CG) character and real background. It requires relatively small number of human resources compared to the full three-dimensional animation pipeline. Hence, it has an advantage in that natural-looking image can be produced under efficient structure and time for rendering can also be reduced. This paper proposes an efficient process of producing composed animation by using miniature set and three-dimensional computer graphic.

This study attempts to describe and periodinate the sixty years history of Korean Geographical Society. For the purpose, several numerical records concerned with the society were employed. The Korean Geographical Society was established in 1945 as a first academic society in geography. The international participation of Korean geographers started when it applied for the IGU membership in 1959. Next year, Korean's application was approved at the 19th IGC in Stockholm. The 40 years later, Korea came to host the 29th IGC in Seoul. This means that the activity of Korean geographers has been vigorous during the 40 years in accordance with high growth of Korean economy. The number of the society member reached 116 in the latter part of 1960s. It grew steadily from 1970s to 1990s and now amounts to around one thousand. It is believed that such trend is associated with the increase of geographical department and the development of graduate programs during past 40 years in Korea. The number of the advanced degree holders was only 2 in 1960, and now reachs 338 among which 166($43\%$) obtained from the foreign country. The Int issue of the society journal 'Geagraphy' -the title was changed to 'Journal of the KGS' in 1993-was published in 1963. It has gradually developed into the annual for $1966{\~}1973$, the semi-annual for $1974{\~}1990$, the quaterly for $1991{\~}1997$, and the hi-monthly until 2005. One issue per year has been published in English since 1993. The annual number of papers accepted by the editorial board has increased from 7 in 1960s-1970s to 52 in the new millennium. In terms of the specialty distribution of total 725 papers after 1963, many Korean geographers have been preferable to the field of socio-economic and urban geography as their major, and next histro-cultural and physical geography. Recently, a growing number of younger geographers are more interested in such diversified fields as ecological geography, socio-historical geography, applied geography concerned with GIS technic, geography education and so on. Such trend is a reflection of the new era which is characterized by diversity, software, high technology, globalization and others. The sixty years history of the society nay be summarized into the five phases of periodization: (1) establishment and chaos($1945{\~}1959$), (2) reconstruction(1960${\~}$1969), (3)reorganization(1970${\~}$1989), (4) jump and rush($1990{\~}1999$), (5)globalization($2000{\~}\;$).

Hana TV and Mega TV have been growing rapidly with IP-VOD service. The number of subscribers of both of them were 1.4 million in April 2008. Additionally, the change of viewing patterns of IPTV subscribers was predicted. Therefore, the purpose of this paper is to see how the subscribers use IP-VOD service practically. For this research, the frequency, the time and the duration of connection by genre have been analyzed on the March of 2007 and 2008. According to the result, there was a significant change quantitatively: within a year, not only the number of subscribers has doubled, but also the frequency of monthly connection has been increased 15 times. In addition, the duration of viewing per person has quadrupled. Regarding to the contents, the subscribers still prefer to watch free TV programs. However, the viewers have their own way of consuming TV programs. It has been proved that IPTV is a complementary media of free TV with a strong possibility to change the viewing patterns in the near future.

The purpose of this study is to identify the trends of emotion-related mathematics education research conducted in Korea so far, and compare them with those of international studies, and explore the desirable directions for future emotion-related mathematics education research. Emotion-related domestic research was collected from domestic academic journals, analyzed, and then it was used as data for international comparative study. The findings of the Eligio(2017) were used as counterpart research data. This study compares the number of publications, research subjects and research topics of domestic and international studies on emotion. Findings indicate that it has generally shown similar patterns to international research although it was difficult to determine the trends due to the lack of the number of domestic studies. The future directions of domestic mathematics education research on emotion were proposed as follows. Since it is difficult to collect reasonable and reliable data on pure emotion due to the nature of emotion in mathematics education research, it is suggested to introduce the concept of emotional intelligence, which is the combination of emotion and cognition. Also, it was recommended to utilize the concept of meta-emotion for future study on emotion-related research.

Levee failure cause the huge amount of damage to human and property. Overflow and erosion of levee are primary cause of a break in a levee but the analysis of breach pattern and impact is partially inadequate. The flow characteristics of meandering rivers are very important in field of river hydraulics that should be studied in practical viewpoints relating to river levee. In meandering the secondary flow that rotary direction is changed reciprocally occurs in three dimension is known. In this study flow characteristics of local river are considered and of meandering channels are analyzed using CCHE2D and FLOW3D. The stability and accuracy of models are examined comparing the measuring and analyzed data for the experimental channel and natural river(Namgang). Consequently, the flow characteristics in a meandering river are suggested precisely and it is essential that river levees having meandering river should be analyzed.

In airlines, on-time performance (OTP) is a measure of an airline's reliability and can be used as an important indicator when compared to other airlines. This study analyzed the effects and strength of delay factors on airline punctuality by analyzing the data of domestic K airlines for one year before and after March 2020, when the number of flights drastically decreased due to the corona virus. In addition, delays caused by seasonal weather effects were analyzed, and how the number of passengers who plummeted due to the corona situation had an effect on delay factors was studied. As for the delay factors, the delay codes of K airline which added its own codes to the delay codes of IATA, were applied. Based on the results of the analysis, we would like to suggest a method to minimize the delay.

This paper deals with the viewer's recognition of diversity on digital media services. For this reason, the researcher focused on the IPTV user, how the perception of the diversity of the digital media service affected the user's satisfaction. The results are as follows. First, digital media service user recognized that supply side diversity of media channel and VOD affect recognition of accessibility (easy of use) and perceived playfulness. Second user recognized that variety of performers and actors affect recognition of accessibility and perceived playfulness. Moreover, it was found that recognition of accessibility, actor's diversity, perceived playfulness affect use's recognition for media player's contribution of diversity, and media satisfaction. As in this paper, the researcher expects that this kind of methodology for confirming of user's recognition of diversity will contribute to preparing a future media policy.
