1631년 조선조 인조때 명나라 사신으로 갔던 정두원은 당시 중국에서 활동하던 포르투갈 선교사 로드리게스로부터 망원경, 서포, 자명종 등을 기증받아 서양문물을 처음 들여왔다. 우리나라에 서양문물을 처음 전한 로드리게스(1561~1633년)는 포르투갈 고아출신 선교사로 일본에 파견되었으며 일본어에 능통하여 당시 일본을 방문한 교황청 주교가 지배자이던 풍신수길을 만났을 때 통역을 맡기도 했다. 로드리게스는 그 후 일본에서 금교령이 내려지자 마카오로 퇴거했는데 중국서 우리 사신에게 이러한 서양문물을 기증한 2년 후에 사망했다.

외뿔소자리 신성 1975는 발견 당시에는 백색왜성과 적색왜성의 근접쌍성계인 것으로 알려졌으나, 엑스선 관측과 그에 따른 표준 정류 상태 원반 모형에 근거한 해석으로 중성자별 또는 블랙홀의 가능성이 대두되었다. 곧이어, 광학관측에 의하여 블랙홀 이중성임이 간접적으로 동정되었다. 최근 들어 1975젼 당시의 많지 않은 전파 관측 자료들을 재해석하여 상대론적인 물질 분출 현상, 즉 마이크로퀘이사 현상이 있었을 가능성이 관측적으로 제시되었다. 우리는 시간 종속적 열적 불안정성 모형을 바탕으로 수치모형을 계산하여 관측적으로 제시된 물질분출의 가능성을 이론적으로도 제시할 수 있음을 보인다

지난 2000년 국내 인터넷 시장에는 다소 생소한 개념의 사업이 등장했다. '콘텐츠 신디케이션'이 바로 그것. 콘텐츠 신디케이션 사업이란 말 그대로 콘텐츠 공급자와 수요자 사이를 연결해주는 사이버 콘텐츠 중개사업을 말한다. 당시 콘텐츠 신디케이션 사업은 폭발적으로 늘어나는 초고속인터넷 가입자와 인터넷 산업의 활성화로 고속 성장을 지속할 것으로 전망됐고 이에 따라 코코사, 코리아컨텐츠네트워크, 디날리코리아, 에드핀, 탑랭커 등 10여개 업체가 출사표를 던졌다. 하지만 2년이 지난 지금 국내 콘텐츠 신디케이션 사업은 아직도 제자리를 찾지 못하고 있다. 지난해부터 시작된 닷컴기업의 붕괴와 인터넷 산업의 침체 여파로 당시 이 시장에 뛰어들었던 업체들 대부분이 사업을 포기해야 했고 현재까지 자리를 지키고 있는 업체는 극소수에 불과하다.

1990년 9월 12일 오전 03시 50분, 9월의 홍수로 인해 한강 하류의 둑인 일산제가 수압을 견디지 못하고 파괴되었다. 이로인해 고양 의 70％가 침수되었으며 인명피해 및 막대한 재산피해가 발생하였다. 본 연구는 동수역학적 원리에 근거한 2차원 범람모형을 수립하여. 일차적으로 일출제 붕괴 당시의 시간에 따른 치수양상 및 치수면적, 침수고를 재현하여 당시의 범람 양상과 비교해보고 추후 개선된 모델링과 범람가능지의 지형자료 입력화를 통해 한강변의 범람시 정확한 예보로서 피해를 경감하는데 그 궁극적 목적이 있다. (중략)

This study was carried out to investigate the variation of instrumental charaters during strorage of pine pollen Dasik stored at room temperature. Cohesiveess, chewness, gumness, adhesiveness and hardness were varied significantly while springness was not influenced by storage periods. Cohesiveness after 45 days storage was significantly different from before storage, however, was not different from that of 30 days stored. Chewness of 30 days stored Dasik was significantly different from that of 15 days stored but was not different from that of 45 days stored. Gumness in the Dasik stored for 30 days was significantly different from that of 15 days stored but was not different from that of 45 days stored Dasik. Adhesiveness was decreased with storage periods. Adhesiveness of the Dasik stored for 30 days long was significantly different from that of 15 days stored but was not different from that of 45 days stored one. Hardness was increased with storage periods. Each of the hardness in the Dasik stored for 0, 15, 30 and 45 days were significantly different from each other.

This article aims at a discourse analysis on the selected 1970s Myungrang Manwhas, in the cases of Ggubungi, Doggaebi Gamtu, Yochul Balmyungwang. For the analysis, the history, pre-censorship, and distribution structure of Myungrang Manwha are referenced, as well as the considerable changes and developments on the definition of 'myungrang' since the 1920s. In employing Foucauldian discourse analysis to the texts, the selected Myungrang Manwhas are analyzed as discursive formation, which emerged within the social relations of the era; the characters' dialogues are analyzed as statement. The analysis examines the discourses that the texts disseminated, and the social context of the utterance. It is demonstrated that the Myungrang Manwhas are forms of representation, which implies 'the contested acquisition on capital and power', 'the emphasis on nationalist aspects', and 'the interpellation and discipline of subject active' of the time. Moreover, it is revealed that the forms of control, such as pre-censorship, were the articulation of the will to power, which drove the discoursive formation to function as an apparatus that meticulously constituted the ruling ideology. In conclusion, the Myungrang Manwhas are rather texts that encompasses political and social context of the era than a mere comic relief.

Purpose: This study seeks to draw out implications that must be considered in the process of establishing measures to evacuate residents in preparation for domestic nuclear disasters by conducting an investigation about the disaster situation at the time of the Fukushima nuclear power plant explosion, emergency warning situation for residents protection, evacuation situation and In addition to investigating problems and measures raised in the resident protection system at that time. Method: A literature survey was conducted focusing on reports published by Japan's national, parliament, local governments and related agencies from right after the Great East Japan Earthquake to the present. Result: Found out what needs to be considered in the process of establishing domestic radiation disaster measures through the results of the survey on the problems and countermeasures derived from the process of evacuation of residents at the time of the Fukushima nuclear power plant explosion. Conclusion: The reviews were classified into four categories and detailed reviews were presented.

Miraculous victory of Myeongnyang sea battle turned the tide of the Joseon's entire war against Japan and it is regarded as one of the most remarkable sea victories in the world history. In the sea battle of Myeongnyang, on September 16, 1597(lunar calender), the Joseon navy with 13 battle ships, led by Admiral Yi Sun-sin, won the Japanese navy with their fleet of 133 warships. There were several reasons why Admiral Yi decided on this location for battle. Myeongnyang strait is so narrow and had currents so powerful that many ships could not pass strait simultaneously. Therefore, despite being vastly outnumbered, Admiral Yi used terrain and tidal current advantage to defeat Japanese navy's numerical advantage. In order to find out the tidal state of Myeongnyang strait on September 16, 1597, topological phase of sun and moon was studied by orbital period of earth and moon. The tidal state of Myeongnyang strait on September 16, 1597 is estimated based on the theories of tide and tide tables. As a result of this study, time of slack water were found to be 0636, 1248, 1906 and time/speed of maximum tidal current were found to be 0930/8.3kts(NW), 1612/9.9kts(SE).

This paper deals with the cultural and ideoligical background of the landscape designs on Joseon blue and white porcelains in the late Joseon period, and involves the government painters in the official kiln. Dongjeongchuwol-design (동정추월문), painted the full-moon night scene of Dongjeong lake on Jeseon blue and white porcelains, was in fashion in the late Joseon period. It didn't reflected the entirely realistic subject comparing to the painting circles at that time, but the principle and aesthetic appreciation of Royal family who leaded the official kiln. And Sansuinmul-design (산수인물화). painted the man of great caliber in the ancient history with mountain scenery, was similar to the painting manuals such as Gossihwabo (고씨화보) and Dangsihwabo (당시화보). It was a counterpart of Dongjeonchuwol-design on Joseon blue and white porcelains in the late Joseon period. These designs were painted into ogival-shaped frame (릉화창) on the blue and white porcelains in most cases, and adjusted to shape of porcelain. The landscape designs on Joseon blue and white porcelains became stereotyped, involving subjects of folk painting in the late 18th Century and the early 19th Century. This essay will be just a start to research into the landscape designs on blue and white porcelains in the late Joseon period, even though we seldom find works providing strict chronology among some works to the public.
