This study applied the text frequency method to analyze the crops prevalent during the Chosunwangjoshilrok dynasty, and categorized the results by each king. Contemporary perception of grains was observed by examining the staple crop types. Staple species were examined using the word cloud and semantic network analysis. Totally, 101,842 types of crop consumption were recorded during the Chosunwangjoshilrok period. Of these, 51,337 (50.4%) were grains, 50,407 (49.5%) were beans, and 98 (0.1%) were seeds. Rice was the most frequently consumed grain (37.1%), followed by pii (11.9%), millet (11.3%), barley (4.5%), proso (0.8%), wheat (0.6%), buckwheat (0.1%), and adlay (0.05%). Grain chronological frequency in the Choseon dynasty was determined to be 15,520 cases in the 15th century (30.2%), 11,201 cases in the 18th century (21.8%), 9,421 cases in the 17th century (18.4%), 9,113 cases in the 16th century (17.8%), and 6,082 cases in the 19th century (11.8%). Interest in grain amongst the 27 kings of Choseon was evaluated based on the frequency of records. The 15th century King Sejong recorded the maximum interest with 13,363 cases (13.1%), followed by King Jungjo (8,501 cases in the 18th century; 8.4%), King Sungjong (7,776 cases in the 15th century; 7.6%).

19-20세기 조선 사회는 격변의 사회였다. 개화기 시점에서 서양 과의 무역통상 조약을 맺음으로 강제화 된 개방을 해야 했다. 조선개화 와 더불어 19세기 서구 선교사들은 조선에 복음을 전하기 위해 다양한 방법을 통해 입국했지만, 폐쇄적이고 서구 종교에 대해 배타적인 자세 로 일관했던 조선에서 선교는 상당한 어려움을 맞았다. 이러한 입장에 서 19-20세기 서구 개신교 의료선교사들은 조선에 입국하여 병원을 세우고 가난하고 병든 조선 사람들을 치료하고 보살핌으로 조선에서 기독교 형성의 발판을 마련했다. 의료선교는 조선 개신교 형성의 출발 점이 되었으며 신앙 공동체의 모체가 되었다. 또한 조선 사회를 새롭게 변혁시키는 변혁의 주체가 되었다. 의료선교사들은 조선에서의 선교적 헌신을 통해 그리스도의 사랑을 실천했으며, 근대 병원 건립을 통해 선진화된 의료기술을 전수했다. 교육의 불모지지였던 조선에 위생교육 을 통해 복음의 접촉점을 마련했다. 나아가 조선간호협의회를 만들어 여성 리더십을 고취시키는 일 등을 마련함으로 조선 개신교 형성과 선교 사역에 지대한 공헌을 하게 되었다.

We arrange Korean ancient calendar with Solar calendar during Choseon Dynasty(A.D. 1392-1910). In this period, we have one representable history books and several books, and most of information for date are found from them, ChoseonWangjosillok(조선왕조실록) and Jeungbomunheonbigo(증보문헌비고), etc. In those books many astronomical data and calendar information data are contained, so we can make chronological tables. Most of the data are arranged based on those several books, and for doubtable data are identified from eclipse, historical events and lunar phase calculations etc. We find that arranged chronological tables during Choseon Dynasty are similar to that of China and somewhat different from that of Japan. In addition we summarize all misrecorded date data in ChoseonWangjosillok
