The National Museum of Korea's 'Shinchungmyeong Jochong' is the sole firearm in the country bearing inscriptions written in ink('辛丑改備江華庫藏'). Thanks to this written record, it is possible to determine where this firearm was stored and to make an estimate of the time when it was stored. Additionally, it is a valuable artifact that has been exceptionally well preserved and has an artistic design. However, research into the operational period, form, and structural characteristics of this firearm has been limited to date. This study aimed to shed light on the operational period, form, and structural features of the 'Shinchukmyeong Jochong.' To achieve this, the specifications and structural characteristics of the firearm were examined, and comparisons were made with 17 other extant firearms and their attributes. The results confirmed that the 'Shinchungmyeong Jochong' is a representative example of the typical firearms of the Joseon Dynasty. Next, the timing, background, and production subject of the Ganghwado containment of the Jochong were tracked based on letters found with the Jochong. The investigation revealed an entry in the 'Records of King Jeongjo'(『正祖實錄』) indicating that a significant amount of military supplies, including firearms, were stored on Ganghwado in December of the 5th year of Shinchung(1781). The decision to store these materials in Ganghwado Island may have been due to the perception of the Joseon decision-makers, who strategically valued Ganghwado Island, and the relocation of 'Tongaoyeong'(統禦營) and the integration with 'Jinmuyeong'(鎭撫營). After acquisition, it is presumed that the firearm was operated at locations like 'Jinmuyeong'(鎭撫營). The firearm's production is presumed to have been associated associated with institutions such as 'Gungisi'(軍器寺). In conclusion, the 'Shinchungmyeong Jochong' exemplifies a typical firearm of the Joseon Dynasty, and it is likely that it was stored on Ganghwado in December of 1781. Its production is believed to have been related to institutions such as 'Gungisi'. Following its acquisition, it is presumed that the firearm was operated at locations including 'Jinmuyeong'.

After the war, the circle literature movement took place in Japan around the 1950s. The subjects of the national movement, the Korean-Japanese, have produced and expanded their political rights and claims through circles and organs in conjunction with the literary movement. However, the results of analyzing the exchanges and conflicts between the political subjects of the Korean national movement and the literary circle movement as a concrete case to date are still insignificant. After liberation, the endless worries and confrontations to the post-colonialization of literary Koreans in Japan were analyzed as 'community with Republic of Korea and Japan', 'topic and creative language', and as 'conflict with Korean association in japan'. The process leading to dissolution was analyzed. The spirit of the era of Koreans in Japan in the 1950s identified in this paper is expected to suggest a new direction for the starting point of study of the humanities in Japan.

After liberation, several literary groups with the nature of the national culture movement joined in Japan in January 1948 to form the Korean-Japanese Joseon Literary Society. However, the Korean-Japanese Joseon Literary Society was unable to play an active role due to the suppression of the GHQ and gathered again as the Korean War Armistice Agreement was concluded in 1953. The institutional journal of the 'Korean-Japanese Joseon Literary Society' is published by changing the magazine name to "Munhakbo" in Japanese and "Joseon Literature", "Joseon Literature and Arts" in Korean. The national movement group of Korean residents in Japan and literature groups were reorganized in conjunction with the political situation in Japan and the Korean peninsula. The reunion of 'Korean-Japanese Joseon Literary Society' was also based on the appearance of 'Jochongnyeon (pro-Pyeongyang federation of Korean residents in Japan)' and 'conversion of line'. In this paper, we are to fill up the blank of the research on literature of Korean residents in Japan in the 1950s by identifying the reality of conflict between 'Jochongnyeon' and 'Mindan', meaning of 'Korean Writing' Movement as a subject of national movement and the issue of promoting self-esteem as a 'citizen of the Republic' that 'Korean-Japanese Joseon Literary Society' tried to convey to Korean readers in Japan.

지구적 차원의 냉전은 끝났다. 한반도의 대립과 갈등도 해결의 실마리가 잡혔다. 그러나 신세계기술질서의 물결이 거세게 밀려오고 있다. 이것은 실리적인 이해가 있는 곳에 경쟁과 마찰이 있음을 뜻한다. 1992년은 임진왜란이 일어난 지 400년이 되는 해이다. "10만 양병론"이 정쟁에 의해 빛을 발하지 못하여 당하였던 국란이 과학기술입국론이 충분히 실천되지 못하여 당하는 기술주천상실로 연결되지 않을가를 피부로 걱정해야 한다. 그 때는 조총이라는 무력 앞에 무릎을 끊었지만, 이제는 소리없이 침투하는 선진국의 기술이 우리를 위협하고 있기 때문이다. 그래서 우리는 우리의 독립·자율·자존을 지키고도 남을 만큼의 "질의 힘"을 갖추어야 한다.

안전성이 중요한 실시간 내장형 시스템인 유도조종장치에서 시간 제약성을 만족하는 것은 매우 중요한 문제이다. 기존 유도조종장치 소프트웨어 개발에서는 주로 테스트 단계에서 시간 제약성 만족을 확인한다. 하지만 이 방법은 늦은 오류의 발견으로 인해 전체 소프트웨어 개발 비용이 커질 가능성이 있다. 이러한 단점을 극복하기위해 본 논문에서는 설계 단계에 정형 기법을 적용하여 유도조총장치 소프트웨어의 시간 제약성을 검증하고자 한다. 이를 위해서 실시간 시스템에 대한 모델링과 검증을 지원하는 TIMES 도구를 유도조종장치 소프트웨어 설계에 적용하는 사례 연구를 수혈하고 그 결과를 분석 및 평가하였다.
