지금까지의 논의를 요약하면 sativa 와 glaverrima 는 독립적으로 분화되었고 sativa 중의 indica 와 japonica 도 원시야생종에서 독립적으로 진화되었는데 중국에서는 japonica와 같이 indica 도 진화되었는데 인도에서는 indica 만이 진화되었다. 벼농사의 시작은 1만년전에 불과하지만 벼 자체의 식물학적인 진화과정은 수백만년의 긴 여정이었다. 벼농사가 중국에서 시작되어 우리나라로 넘어오기까지에 5,000 년을 소요했는데 지금까지의 고고학적 증빙으로는 법금 5000-2300년 사이에 한반도 전역에 벼농사는 널리 전파되었다. 한국으로 전래되기까지의 경로와 연대를 추정하기에는 아직 자료가 많이 부족하다 특히 화분화석, 규화석, 고기후학, 고지리학 그리고 황해의 항해에 관한 자료가 아쉽다. Oka 가(1988) 인도부터 중국에 걸친 지역에서 고고학적 연구가 보다더 진전되기까지는 벼의 식물과 재배의 기원을 결정적으로 말할 수는 없을 것이라고 결논한 것은 이런 사정을 분명히 표현한 것으로 생각된다.

Performance tests of a supersonic exhaust diffuser were conducted by using a liquid rocket engine for simulating high-altitude environment. The experimental setup consisted of a combustion chamber, a vacuum chamber and a diffuser. The combustion tests for simulating high-altitude environment were carried out at three cases by chamber pressure variation(26, 29, 32barg). The test results showed that the diffuser was started at all case and vacuum chamber pressures were approximately 140torr. The starting pressure using combustion gas was similar with that of cold gas, but the vacuum chamber pressure was relatively high because of high temperature in the vacuum chamber. The results of this test can be used as an essential database for the design of real-scale high-altitude simulation test facility in the future.

Up until the early twentieth century in Germany, there were two research trends: 1) emphasizing objectives and making detailed observations of archaeological artifacts and sites, 2) tracing the remains of specific nations or ethnic groups and defining their temporal-spatial boundaries by conducting research on material culture in terms of nationalism or ethnocentrism. After the Second World War ended and Germany was divided, West German archaeology focused on observations of artifacts and sites, cataloging them, and doing research on chronology and distribution following their own traditional methodologies. East German archaeology attempted to prove the developing process of history and its Marxist principles based upon material culture and to examine the historic value of inherent specific cultural heritage based on criteria regarding how it corresponded to socialism and contributed to the development of socialism. Nevertheless, East and West German archaeology shared traditional archaeological methods inherited from German archaeology since the nineteenth century, and contact between archaeologists in West and East Germany continued to a degree. Furthermore, East German archaeology produced significant archaeological achievements acknowledged by West German and European archaeologists. These facts provided the momentum to complete rapid incorporation of the archaeologies of West and East Germany in spite of a one-sided process imposed by West German archaeology. In the case of Korea, it seems necessary to make an effort to share common research history and traditions and to encourage mutual academic exchange (e.g. joint excavation and archaeological research). Furthermore, it is also imperative to have open-minded attitudes toward accepting substantial results and interpretations achieved by North Korean archaeologists under scrutiny when and where necessary, despite seeming to have been fossilized by Marxism and Juche ideology. Any efforts to narrow the gap in archaeological research and conservation of cultural heritage between the archaeologies of South and North Korea should be made immediately. The case of Germany demonstrates how such a project could proceed efficaciously.

This paper examined archaeological resources that discuss how Silla entered the Gangneung area, the coastal region along the East Sea that has been excavated most actively. Silla expanded its territories while organizing the its system as an ancient state and acquired several independent townships in various regions, stretching its forces to the East Sea area faster than any other ancient states of the time. In particular, many early relics and heritages of Silla have been found in Gangneung, the center of the East Sea area. Many archaeological resources prove these circumstances of that time and provide brief texts that are valuable for our interpretation of historical facts. In this respect, it was possible for me to examine these resources to answer my question as to why early relics and heritages of Silla are found in the Gangneung area. Based on my research on Silla's advancement into the Gangneung area, I have acquired the following results: How did Silla rule this area after conquering Yeguk in the Gangneung area? After conquering the Gangneung area, Silla attempted an indirect ruling at first. Later, Silla adopted a direct ruling system. I divided the indirect ruling period into two phases: introduction and settlement. In detail, Silla's earthenware and stone chamber tombs first appeared in Hasi-dong in the fourth quarter of the 4th Century and the tombs spread to Chodang-dong in the second quarter of the 5th Century. A belt with dragon pattern openwork, which seems to be from the second quarter of the 5th Century, was found to tell us that the Gangneung region began receiving rewards from Silla during this time. Thus, the period from the fourth quarter of the 4th Century to the second quarter of the 5th Century is designated as the 1st Phase (Introduction) of indirect ruling in terms of aechaeological findings. This is when Silla was first advanced to the Gangneung area and tolerated independent administration of the conquered. In the third and fourth quarters of the 5th Century, old mound tombs appeared and burials of relics that symbolized power emerged. In the third quarter of the 5th Century, stone chamber tombs were prevalent, but wooden chamber tombs, stone mounded wooden chamber tombs, and lateral entrance stone chamber tombs began to emerge. Also, tombs that were clustered in Hasi-dong and Chodang-dong began to scatter to Byeongsan-dong, Yeongjin-ri, and Bangnae-ri nearby. Steel pots were the symbol of power that emerged at this time. In the fourth quarter of the 5th Century, stone chamber tombs were still dominating, but wooden chamber tombs, stone mounded wooden chamber tombs, and lateral entrance stone chamber tombs became more popular. More crowns, crown ornaments, big daggers, and belts were bestowed by Silla, mostly in Chodang-dong and Byeongsan-dong. The period from the third quarter to the fourth quarter of the 5th Century was designated as the 2nd Phase (Settlement) of indirect ruling in terms of aechaeological findings. At this time, Silla bestowed items of power to the ruling class of the Gangneung area and gave equal power to the rulers of Chodang-dong and Byeongsan-dong to keep them restrained by each other. However, Silla converted the ruling system to direct ruling once it recognized the Gangneung area as the base of its expedition of conquest to the north. In the first quarter of the 6th Century, old mound tombs disappeared and small/medium-sized mounds appeared in the western inlands and the northern areas. In this period, the tunnel entrance stone chamber tombs were large enough for people to enter with doors. A cluster of several tunnel entrance stone chamber tombs was formed in Yeongjin-ri and Bangnae-ri at this time, probably with the influence of Silla's direct ruling. In the first quarter of the 6th Century, Silla dispatched officers from the central government to complete the local administration system and replaced the ruling class of Chodang-dong and Byeongsan-dong with that of Silla-friendly Yeonjin-ri and Bangnae-ri to reorganize the local administration system and gain full control of the Gangneung area.

A ground penetrating radar survey with a 500 MHz radar antenna was applied to make archaeological investigation in Nakajima of Ishikawa Prefecture, Japan. The ability of the radar system to aid in the archaeological preservation of burial ground was the primary concern of the experiments. The average variance of the radar wave returned from progressively deeper reflectors in a tomb were contoured at 2.4 nanoseconds intervals. The results of analysis indicates the location of trenches and the coffin area at the tomb site. The orientation of the coffin is dearly defined on contour maps made below 9.6 nanoseconds horizon. The general features detected by the GPR were also reconfirmed by electric resistivity survey made at the site. The radar was accurate in ascertaining the location, orientation, and the general construction style of the coffin.

This article found that establish of the new study, "Archaeology of Textile", and its process of development based on the Silk Road from China. Archaeology of Textile which is formed by the modern archeology in the 20 centuries developed is a research focused on textile and is required experts knowledge of archaeology, natural science, and history of textile. Textiles are the most difficult to handle of existing antiquities and it is rare to be excavated perfectly. However, the early archaeologists were interested in the Silk Road inconsistently. There were various kinds of silk and embroidery in the center of excavation process. In China, there are still numerous textiles have been excavating from across the country which has leaded to the top level of the textile study in the world. Compare to China, Korea hasn't excavated textile much, and we've been having a difficulty to research with small pieces of textile fabrics. With lack of understanding of textile, it is insignificant to excavate relic such as Chunma-Chong(天馬塚), tomb of king Muryeong(武寧王陵) which has started in-depth studying after 30 years later since it was discovered. Accordingly, a history of archeological textile will be introduced and make sure the possibility of study of excavated textile will make sure through this study.

The establishment of the Bronze Age is one of the most important achievements suggested by Korean archaeology shortly after liberation. There is no doubt that Moo-Byung Yoon is the representative figure, who refuted the ambiguous Eneolithic age (金石倂用期) created by Japanese scholars and settled the concept of the Bronze Age. In this article, the author takes a new look at Yoon's institutional role in studying the Bronze Age in Korea. Until now, Yoon's representative achievement has been his typology of the Slender dagger of the Korean Peninsula. However, it is not less important that Yoon also established the Bronze Age concept with the excavation of a dolmen and a Bronze Age subterranean dwelling in Oksok-ni, Paju during the 1960s. Of course, it was not a personal assignment for Yoon. He was aided by Prof. Kim Won-Yong's work, who had introduced newly excavated materials from North Korea and China; these materials gave some insight for establishing the Bronze Age concepts in the 1960 and 1970s. Kim's suggestion about the possibility of a Korean Bronze Age led to Yoon's refined typological study on Korea's bronze wares. However, Yoon's excessive schematic classification of artifacts and reliance on the Japanese chronology became an obstacle for making the Korean Bronze Age isolated from East Asia. As a result, it is regrettable that his research led to the "cultural lag" phenomenon of Bronze Age research. Meanwhile, Japanese archaeology, which had influenced Yoon, also faced a major change. In 2003, the Japanese archaeological community revised the Yayoi culture's beginning around the 1,000 BC. This means a shift in the perception that we should understand Japan's Bronze Age in the context of the East Asian continent. Of course, it is not appropriate to reevaluate or denigrate Yoon's research from the current view. Rather, it is necessary to recognize the limitations of Yoon's time and present a new path to research by combining the archaeological tradition of refining research on the relics he maintained with a new chronological view and a macro view of East Asian archaeology. This is why we should take a new glimpse into Yoon's research.

이 논문은 미국의 남서부지역(대략, 애리조나 주, 뉴-멕시코 주, 콜로라도 주, 그리고 유타 주 등에 해당)에서 발굴 조사된 수혈주거지들의 방향을 열효율과 연계하여 연구한 것이다. 이 지역 선사시대 수혈주거지에 거주했던 사람들은 주거지 내부에 있었던 작은 노지(爐址) 이외에 다른 난방시설이 없었기 때문에 고고학자들은 이 지역 주민들이 주거지를 설계할 때 자연난방인 태양열을 이용하였을 것이라고 추정하고 있다. 이 아이디어를 고고학 자료를 통하여 검증하기 위하여 기원 전후부터 기원 후 미국 남서부 지역에서 가장 주도적인 역할을 하였던 원주민들의 호호캄(Hohokam, 남부 애리조나 지역), 아나사지(Anasazi, 북부 애리조나, 뉴-멕시코, 남서 콜로라도와 남동 유타에 걸쳐져 있던 四隅지역), 그리고 머기욘(Mogollon, 남동 애리조나와 남서 뉴-멕시코 지역) 문화 유적지에서 발굴조사된 수혈주거지들의 깊이, 모양, 그리고 방향에 대해서 검토하여 보았다. 동시에 수혈주거지의 방향의 해석과 관련된 하부구조적 측면과 관념적 측면의 두 가지 상반되는 견해에 대해서 검토하여 보았다. 이들 지역에서 발굴조사된 주거지들의 방향을 분석하여 보아 일관성 있게 남쪽으로 난 주거지들의 방향이 초자연적인 의미를 내포한 것 이라기보다는 적응의 전략으로서 태양열의 이용을 염두에 두었을 가능성이 더 높다는 것을 주장하였다. 주제어: 선사시대, 미국 남서부 지역, 고고학, 건축, 수혈주거지, 방향, 태양열, 실용성, 상징성ン?⨀⣳?⨀㋳?⨀?⨀

This study examines the state of archeological research on Silla and Unified Silla conducted in North Korea and identifies its characteristics. In South Korea, most research has focused on prehistoric times in North Korea, and little research has been done on Silla and Unified Silla. Noting this, we attempted to examine the history of archaeological research in North Korea to provide foundations upon which to go forward. The research was examined in terms of general archaeological themes including tombs, fortresses, the capital city, earthenware, roof tiles, ornaments, weapons, and horse harnesses, and we identified four characteristics from the examination. First, Juche ideology had a great influence on interpretation of the unification of the three kingdoms. The Juche ideology was first proposed in 1955, and at the time, it was not fully established as an ideology but rather seen as constituting opposition to toadyism. Accordingly, the unification of the three kingdoms led by Silla was seen as amounting to collusion with foreign forces and was not acknowledged. A piece of evidence shows that this change took place around 1962. Second, an inclination to testify to the 'uniqueness' of the cultures of the three kingdoms is observed. The argument is that culture in the Korean peninsula has unique characteristics that set it apart from Chinese culture, and that the cultures of the three kingdoms share much in common. This inclination was not mentioned in research until the 1950s, and it can be seen as an effort to comply with Juche ideology and prove the principle of unity as stated in the national leader's instructions in the 1960s. Third, the influence of Goguryeo on the formation of Silla culture is emphasized. Related research explains that Baekje, Silla, and Gaya adopted the 'superior' culture of Goguryeo, and could establish 'uniqueness' of culture accordingly. It is claimed that an advanced Goguryeo culture was disseminated throughout Balhae and Unified Silla, and then to Goryeo, resulting in a true unification of the ethnic culture. Fourth, researchers in North Korea presume the Silla tombs and other relics to be far older than South Korean researchers' estimate. From a standpoint of highlighting the long history of Korea, they estimate the Silla Dynasty was founded in the early or mid-first century. Accordingly, archeological evidence that demonstrates the establishment of the state is dated as far back. Such an estimate is also indispensable in justifying the explanation that the chamber tombs of Goguryeo had a direct influence on Silla. These research characteristics which arose during the 1960s continue to be basic guidelines for North Korean researchers.

Archaeological survey has been carried out to find some evidence of human occupation in 31 caves in Pyeoungchang, Danyang, Jincheon, Goesan, Munkyoung, Boeun, Sangju in central limestone area of the Korean peninsula. Among those caves, some archaeological evidences were observed in 11 caves. Various types of potteries, animal bones and stone artifacts were collected on surface of sediments in caves. Among them, the Mosan cave in Munkyoung and the Kwangcheonseongul in Pyeoungchang are very likely to yield important archaeological remains in the well preserved deposits in the caves. Further researches are expected to provide significant information for explaining human living from prehistoric time to historical periods.
