인류사상 가장 많은 책을 쓴 과학자로 알려진 아이작 아시모프는 1992년 4월 6일 심장병으로 타계할 때까지 5백종에 가까운 저서를 남겼다. 기네스북에 따르면 세계에서 가장 많은 저서를 쓴 사람은 5백종 이상을 펴낸 영국의 미스테리작가 존 크리지로 기록되어 있으나 과학을 비롯하여 문학과 종교에서 역사와 어린이 읽을 거리에 이르는 광범위한 분야를 넘나들면서 그처럼 많은 저서를 남긴 사람은 찾기 어렵다. 그는 분당 90단어를 타자하면서 50세가 되기 전에 1백종을 출간했으나 그로부터 저술작업에는 더욱 가속도가 붙어 다음 22년간 4백종을 더 펴냈다. 그는 이렇게 많은 저작을 하기 위해 창문의 차양을 내려 놓은 방에서 1주일동안 하루도 쉬지 않고 글쓰는 일로 지샜다. 그는 탄탄한 과학지식을 배경으로 매우 정확하면서도 누구나 쉽고 재미있게 읽을 수 있는 글을 통해 과학대중화의 측면에서는 수천명의 과학자 못지 않은 위업을 남긴 것으로 평가되고 있다. 그는 작품을 통해 오늘날 로봇이 조업하는 조립공장을 이미 1939년에, 그리고 컴퓨터혁명을 1950년에 예언했다.

This study derived big issues in overseas construction through big data analysis. To derive big issues in overseas construction, candidate groups of big issues were identified through big data analysis targeting 53,759 issues including 39,436 issues from major portal sites, 10,387 issues from daily newspapers, and 336 issues in construction magazines from Oct. 1, 2016 to Sep. 30, 2017. The main results are as follows: First, the main issues of overseas construction for the past one year showed that markets were concentrated in Middle East Asia and most of them were low-price order plant projects, which revealed the limitations. Although orders of overseas construction were slightly upward in the first half of 2017 compared to previous year, overseas construction orders are still unstable due to uncertainties in the international affairs and drops in oil prices. Second, the interest topics based on the 8th core keywords of overseas construction among the overseas construction issues for the past one year showed that region (29.9%), corporation environment (22.0%), profitability (17.0%), organizations (15.1%), projects (5.2%), market environment (3.6%), policy and system (3.6%), and education (3.5%) in the order of interest. Third, 10 core issues that have expandability and persistence of discourse were extracted out of 30 issue candidates with regard to eight keywords. Based on the extracted issues, detailed analysis on each of the core issues in overseas construction and correlation analysis between 10 core issues were conducted.

In Korea, there are four institutions related to atmospheric science: the university's atmospheric science-related department, the Korea Meteorological Administration (KMA), the ROK Air Force Weather Group, and the Meteorological Industry Association. These four institutions have developed while maintaining a deep cooperative relationship with the Korea Meteorological Society (KMS) for the past 60 years. At the university, 6,986 bachelors, 1,595 masters, and 505 doctors, who are experts in meteorology and climate, have been accredited by 2022 at 7 universities related to atmospheric science. The KMA is carrying out national meteorological tasks to protect people's lives and property and foster the meteorological industry. The ROK Air Force Weather Group is in charge of military meteorological work, and is building an artificial intelligence and space weather support system through cooperation with universities, the KMA, and the KMS. Although the Meteorological Industry Association has a short history, its members, sales, and the number of employees are steadily increasing. The KMS greatly contributed to raising the national meteorological service to the level of advanced countries by supporting the development of universities, the KMA, the Air Force Meteorological Agency, and the Meteorological Industry Association.
