전자해도는 IHO의 S-57 ENC Product Specification에 따라 해양의 모든 지형정보를 포함하는데, 해양의 지형정보에는 해안선, 등심선, 수심 그리고 항로표지 등이 포함된다. 전자해도가 포함하는 정보는 수로측량을 통해 제작된 측량원도를 이용하여 제작하는데, 대용량의 측량원도 자료는 매우 조밀하고 양이 방대하여 전자해도에 반영하기 위해서는 수심 정보를 발췌하여야 한다. 국립해양조사원에서는 측량원도의 정보를 발췌하기 위한 방안으로 수심편수규칙을 정하고 있으며, 편수 단계와 편수 후 검증 단계를 거쳐 전자해도의 수심 정보를 제작하고 있다. 그러나 편수와 편수 후 검증은 모두 수작업으로 진행하고 있어, 보다 효율적이고 정확한 방법으로 수심 편수 결과를 검증하기 위한 방안이 필요하다. 본 논문에서는 수심 편수 결과를 규칙에 맞도록 편수되었는지를 평가하는 방안을 연구하였다. 각 편수된 수심을 들로네 삼각분할 기법에 따라 영역을 삼각분할하고, 측량원도의 수심 정보와 삼각분할 된 삼각형과 비교 분석하여 수심이 수심편수규칙을 준수하는지를 비교분석하였다.

In this study, temporal trend of researches in earthquake with groundwater level, water quality, radon, remote sensing, electrical resistivity, gravity, and geomagnetism was searched from 2001 to 2020, using the journals indexed in Web of Science, and the number of articles published in international journals was counted in relation to the occurrences of earthquakes (≥Mw 5.0, ≥Mw 6.0, ≥Mw 7.0, ≥Mw 8.0, and ≥Mw 9.0). The number of articles shows an increasing trend over the studied period. This is explained by that studies on earthquake precursor and seismic monitoring becomes active in various fields with integrated data analysis through the development of remote sensing technology, progress of measurement equipment, and big data. According to Mann-Kendall and Sen's tests, gravity-related articles exhibit an increasing trend of 1.30 articles/yr, radon-related articles (0.60 articles/yr), groundwater-related articles (0.70 articles/yr), electrical resistivity-related articles (0.25 articles/yr), and remote-sensing-related articles (0.67 articles/yr). By cross-correlation analysis of the number of articles in each field with removing trend effect and the number of earthquakes of ≥Mw 5.0, ≥Mw 6.0, ≥Mw 7.0, ≥Mw 8.0, and ≥Mw 9.0, radon and remote sensing fields exhibit a high cross-correlation with a delay time of one year. In addition, large-scale earthquakes such as the 2004 and 2005 Sumatra earthquake, the 2008 Sichuan earthquake, the 2010 Haiti earthquake, and the 2010 Chile earthquake are estimated to be related with the increase in the number of articles in the corresponding periods.

Over the years(1971 to 1987), only 20 Korean film production companies had been granted the exclusive rights to make Korean films in Korea and to import foreign films with a quota system. They had been making trashy Korean movies to secure import quotas of foreign films. Newcomer's entry of market had also been limited and the growth of Korean films through innovation had been hampered. In the same period, The annual number of Rookie director is 10, the portion of debut films of all Korean films is 10.62%, and the audience portion of debut is only 10.5% of Korean movie audience. From 2004 to 2016, total number of rookie directors is 874, and 61.72% of 1,416 directors who made his debut over the 46 years from 1971 to 2016. This is far more than the number of directors who debuted for the last 32 years. From 2004 to 2016, the annual number of rookie directors is 62.15 and their debut film occupies 39.58% of the total amount of Korean movies released and 32.8% of the audience number. Since the full opening of the domestic market to foreign films industries in 1988, the liberalization of independent film production in 1999, as a result of innovation of a competitive system, the Korean movies have been loved by audiences. However, there are concerns that the decline of the screen quota in 2006, the monopoly of the 4 major distributors, increase in indie movies and Semi-adult movies for VOD, could be the potential threat for future innovation in Korean cinema.

학회의 성격과 활동 및 발전과정을 가장 잘 표현하고 있는 것이 회지인 까닭에 전기학회지야말로 본학회의 얼굴이라고 할 수 있습니다. 본회지는 1948년 10원 1일에 발간된 이래 학회발전과 더불어 성장하여 최근에 화서는 학술지로서의 면모를 갖추게 되었습니다. 이것은 회원 여러분의 적극적인 참여와 전임 편수진의 꾸준한 노력의 결과라고 생각할 때 새로이 편수를 맡은 우리들은 공든 탑을 무너뜨리는 것만 같은 염려가 앞섭니다. 여러 회원들께서 잘 아시는 바와 같이 본회는 총회 학술발표, 강연회, 심포지움 및 각종 세미나등의 많은 활동에 회원여러분들이 참여하고 있지만 대다수의 회원들은 격월로 배포되는 회지를 통하여 학회의 소식을 아는 동시에 학회와 접촉하고 있다는 것이 학회지의 일면입니다. 또한 학회지는 전기기술이라는 전문분야에 있어서 기술 수준의 현황, 진보 및 장래의 동향 등을 소개하는 임무를 수행하여야 하며 회원 여러분들이 투고한 귀중한 연구논문을 심사하여 기재하여야 합니다.

A statistical model for the relation between KARP membership and articles published in the KARP Journal on the yearly basis was obtained by using the least-squares method. From this, KARP membership potent to publish the KARP Journal up to 4 numbers a year were projected. It is revealed that at least 650 KARP members are needed.

As the important factors to improve research performance, the researchers' capacity and the input of resources like research funds have been pointed out. As joint researches are recently vitalized, however, the scientific knowledge is produced by forming continuous mutual relations through the structural characteristics between researchers. Since the support of research funds becomes a foothold to perform researches as multiple institutions cooperate with each other, it can be considered to have influence on research performance. In other words, it can be estimated that the support of research funds has influence on research performance by generating differences in the connecting structure of joint researches. In the results of analyzing the relation between network structure and research performance in accordance with the matter of supporting research funds, targeting the joint research theses in the culture technology(CT) area for five years from 2009 to 2013 in SCIE DB, when multiple research institutes are connected to each other, the number of thesis is increased. When the betweenness centrality is increased, the number of thesis is decreased. Also, the matter of supporting research funds has influence on network structure and research performance.

This study had suggested the direction and implications of mathematics education for the gifted student by looking into domestic research trends in relation with mathematics education for the talented children from 2000 to 2010. 168 theses were analyzed by researching theses about mathematics education for the talented children and the total 10 kinds of special journals that are registered or to be registered at National Research Foundation of Korea in order to find a research trend about mathematics education for the talented children. As a result of analyzing theses of each year, the number of theses on mathematics education for the talented children has been increasing largely since2004 and it is steadily being conducted until now. As a result of analyzing theses for each research theme, frequency was shown in order of development research about educational course program for mathematics education for the talented children and research on characteristics of the talented children. For analysis result of research target, research targeting elementary school students has taken great importance. For the aspect of research methods, research about development of program and research tool was used in theses and qualitative research method was mainly used in journals and therefore a direction of mathematics education for the talented children was discussed according to this.

The purpose of this study is to investigate research trends about convergence and integrated science education through the analysis of theses published from January, 2000 to June, 2011 in the scientific journals. For the analysis of the theses, we set standards of analysis including the number of theses, integrated types, research methods, the designs of study and the objects of study. The number of theses used for the analysis were 110 volumes and these were limited to the Journal of KASE (The Korean Association for Science Education) and Journal of KESES (The Korean Society of Elementary Science Education). The results of the study are as follows. First, in the analysis of theses according to the published year, we discovered that the volumes of theses related to convergence and integrated science education were only about 10% of theses published in the journals. Second, the theses about STS education and integration type were the most common type in the integrated types, and the next things were integration type with other scientific fields, and integration type with other subjects. Third, 50% of theses have focused on the 'analysis of effect' as research methods and 45.5% of the theses have used 'quantitative research' as the designs of study. Fourth, the most common study in the theses was to target elementary school students, then it was middle school students, then high school students, literature, teachers, would-be teachers, and the general public. On the basis of the results of this research, we suggest that various studies can develop student's creativity and teacher's recognition through STEAM education and must be presented for the successful STEAM education.
