The origin of Korean petroglyphs was investigated mainly in Inner Mongolia and Liaoning provinces, China, but there was no research in the Heilongjiang Province area, so we looked at the “海林市 群力” Petroglyphs in the Heilongjiang Province. These petroglyphs feature drawings of deer and ships. There are various views in Chinese academia about the time of the production of the petroglyph, from the perspective of prehistoric times to Eupru(挹婁) or Okjeo(沃沮), Malgal(靺鞨) and Balhae(渤海). In addition to revealing the origin of rock art on the Korean Peninsula made during the Neolithic and Bronze Age, Okjeo(沃沮), Eupru(挹婁) and Balhae(渤海) in the historical era are also closely related to the Korean people, so more attention should be paid to the research on the origin of Korean history.

In the Korean and Japanese films analyzed in this study, the form of residence shown as‘lifetime share houses' showed a new form of family. Also, unlike the past, as the form of the family changed into a fluid concept, these films have shown alternatives to family. Through a film depicting the process of unrelated characters meeting and becoming a family, it was clear that there should be bonds, commonalities, and warmth among members in the home and in the shared space. In a film depicting the birth of such a new family, it showed that a normal family fixed in the frame, that hurts each other by losing their composure because they are family members, but a non-blood relative family is more caring and soft family that maintains their psychological equanimity. Therefore, it can be said that the communal life of people without kinship is not a community formed solely for economic reasons, but a" similar family" that becomes a family. Therefore, it is necessary to continue to study the lifetime-type share houses already under way in Japan, and Korea may consider a lifetime-type share house as an alternative that can be of economic and emotional help to single-person households, including the socially disadvantaged, rather than blood-related families.

The objective of this article is to study political changes in the Korean Peninsula in 550s and trends of Yamato Wa. Baekje asked Yamato regime five times to provide military assistance to prepare for the war against Silla, but Japan did not immediately provide its soldiers and only sent about 1,000 soldiers. At that time, Baekje was in a situation where it had to receive military support for its national interests. It was also intended to make Silla and Goguryeo aware of the diplomatic relations of Baekje and Yamato Wa regardless of the size of the military assistance. On the other hand, the Yamato Wa focused only on the means of receiving advanced cultural support from Baekje. While sending as few of its soldiers as possible for the national interest, the Yamato government sought to receive a large amount of advanced cultural support from Baekje. It is also believed that the Yamato regime at that time was reluctant to request from Baekje due to domestic circumstances such as the formation of the new dynasty and the confrontation of major clan forces. In addition, the supply of troops was not provided by the Yamato regime but by the individual clan support system.
