송산리 29호분의 시기와 계통에 대한 검토: 최신 조사·연구 성과를 바탕으로

김환희(Kim Hwanhee),이나은(Lee Naeun) 한국고고학회 2021 한국고고학보 Vol.- No.120

송산리 29호분은 구조적으로 전통적인 석실에 새로운 전실의 요소가 가미된 구조로, 당시 사회·문화상이 장례문화에 직접적으로 영향을 주고 있음을 보여준다. 송산리고분군의 가계는 북동쪽 구릉에 위치한 1~4호분을 문주왕-삼근왕계로, 남서쪽 구릉에 위치한 무령왕릉, 5·6·29호분을 무령왕계로 정리하였다. 고분의 축조 순서는 입지적 특징과 구조, 출토유물(관정) 등을 검토한 결과, 2~4호분 → 1호분 →무령왕릉→6호분→5호분→29호분으로 추정하였다. 다음으로 일제강점기에 조사 보고되었던 내용과 최근 실시된 29호분의 재발굴조사 성과를 종합하여, 29 호분의 시기와 계통에 대한 검토를 진행하였다. 시기를 파악할 수 있는 중요한 단서는 29호분에서 출토된 화형두정, 반구형원두정, 평방두정이었다. 화형두정과 평방두정의 경우 웅진기에도 계속 사용되지만, 반구형원두정의 경우 사비천도를 전후한 시기인 6세기 중엽에 등장한 것으로 편년되어서, 유물 간의 시기 차이가 확인된다. 즉 29호분에서 출토된 반구형원두정도 6세기 중엽으로 편년할 수 있으며, 반구형원두정과 평방두정이조합된 목관B는 6세기 중엽, 즉 사비기 초에 추가장된 것으로 추정된다. 마지막으로 29호분의 피장자가 누구인지(계통)를 추정하였다. 29호분의 피장자는 무령왕계의 혈족으로, 가계의 마지막 단계에 매장된 것으로 파악하였다. 또한 앞서 검토한 여러 내용들을 종합하여 당시 29호분의매장 상황을 그려보면, 웅진기 말에 사망한 왕족 여성이 목관A에 입관되어 서쪽 관대에 안치된 이후, 6세기 중엽, 즉 사비기 초에 사망한 왕족 남성이 목관B에 입관된 후 동쪽 관대에 안치된 것으로 추정된다. S ongsan-ri Tomb No. 29 represents a merging of the use of brick with the traditional stone chamber tomb architecture, illustrating that the social and cultural aspects had direct impact on the burial culture of the time. The tombs of Songsan-ri have been established as follows: Tombs No. 1 to No. 4 located along the northeast hill belong to the line of King Munju to King Samgeun; the Tomb of King Muryeong and Tombs No. 5, No. 6, No. 29, located along the southwest hill belong to the line of King Muryeong. An examination of their construction order, based on location, structural features, and artifacts (in particular, coffin nails), can be suggested as follows: Tombs No. 2 to No. 4 were first built, followed by Tomb No. 1, the Tomb of King Muryeong, and Tombs No. 6, No. 5 and No. 29, in that order. This study then reviewed the temporal position and genealogy of Tomb No. 29 by putting together the survey reports dating to the period of Japanese Occupation and the recent re-excavation survey of the tomb. Important clues for figuring out the time period of construction were found in the coffin nails with flower-shaped head, semi-globular head, and square head excavated in Tomb No. 29. It is presumed that the coffin nails with flower- shaped and square heads were used during the Ungjin period, whereas coffin nails with semi-globular heads were seemingly produced in the middle of the sixth century, around the time of the relocation of the capital to Sabi. This suggests that wooden coffin B from Tomb No. 29, featuring a combination of coffin nails with semi-globular and square heads, was added to the tomb in the middle sixth century, in the early part of the Sabi period. Finally, this study explored the identity (geneaolgy) of the deceased buried in Tomb No. 29. It was suggested that one of King Muryeong’s kin was buried in the tomb at the last stage. In considering together various lines of evidence previously discussed, it was established that after a royal female had passed away at the end of Ungjin period, was put into wooden coffin A, and placed upon the western coffin bed, a royal male had passed away in the middle of the sixth century, the early Sabi period, was put into woodden coffin B, and placed upon the eastern coffin bed.

제석사지 폐기유적의 시기와 형성에 대한 재검토

김환희(Kim, Hwanhee),이나은(Lee, Naeun),우상은(Woo, Sangeun),조지현(Cho, Jihyun) 한국고고학회 2021 한국고고학보 Vol.- No.118

제석사지 폐기유적은 제석사가 639년 뇌우로 인해 불탄 후 발생한 폐기물을 일시에 버렸던 장소로 알려져있다. 그러나 3년간 진행된 발굴조사 결과 폐기는 일시에 이루어진 것이 아니라 최소 2차례 이루어졌다는 사실이 확인되어, 기존의 논의를 재검토할 필요가 대두되었다. 또한 제석사보다 고도가 높은 곳에 위치한 제석사지 폐기유적의 입지상 비효율성을 어떻게 해석하고 받아들일 것인지에 대한 이견도 여전히 존재한다. 이에 본고에서는 제석사지 폐기유적의 발굴조사에서 보고된 폐기양상의 면밀한 검토, 출토유물의 과학적 분석, 시대별 지형 분석, 국내외 고대 사찰의 폐기장소 유사 사례 검토 등 다각적인 접근을 통해 유적의 시기, 성격, 형성 과정 등을 규명하였다. 먼저 층위양상 검토와 출토유물 분석 결과, 1차 폐기층 형성 → 1호 석곽묘 조성 → 1호 석곽묘 훼손 및 노출 → 2차 폐기층 형성이라는 4단계의 변화 과정을 거쳐 형성되었음을 확인하였다. 특히 2차 폐기 원인으로는 제석사 재건과 관련된 대지 정리 작업에서 나타난 것으로 추정하였다. 다음으로 출토유물의 과학적 분석을 통해 가마가 아닌 화재로 인하여 발생한 2차 피열임을 확인하여 유적의 성격이 폐기유적임을 규명하였다. 마지막으로 지형 분석 결과, 폐기유적이 곡부가 시작되는 끝자락에 입지한 점을 통해 시각적으로 폐기물을 감추기 최적화한 곳으로 추정하였다. 또한, 두 유적을 직접 잇는 서쪽의 도로가추가로 확인되어 폐기물 운반의 새로운 루트와 효율성을 확인하였다. 또한 국내외 고대 사찰의 폐기장소 유사 사례를 검토한 결과, 폐기행위는 규칙성 없이 상황에 따라 취사선택되어 형성된 것임을 파악하였다. It has been known, based on reviews of literature records and the results of excavation research, that the Jeseoksa Dump-site was a place where waste that was produced as a result of the fire started by the thunderstorm of 639 was disposed of. However, the results of excavations that took place over three years has revealed that the act of disposal did not take place over one occasion but took place twice. It has therefore become necessary to review existing discussions that have taken place on this topic. Different opinions still exist over how to interpret the Jeseoksa Dump-site, as well as how to come to terms with the inefficient location of the Dump-site, which was located at a higher altitude than the Jeseoksa Temple site. In an effort to investigate the formation process, period, and nature of the feature, this study conducted a multi-faceted review which included an analysis of the topography of the area where the Dump-site had been located according to period, an examination of the disposal patterns confirmed through excavation, the undertaking of scientific analysis on the artifacts excavated at the site, and a review of similar cases from home and abroad. The topographic analysis results revealed an additional road to the west that connected to the Jeseoksa Dump-site, which leads to the suggestion that road conditions had been suitable enough to enable transportation in the area. In addition, the Dump-site stood at the end of the curved section where the road started, which suggests that its location had been chosen due to its suitability for hiding the Dump-site. A review of the stratigraphy and an analysis of the excavated artifacts indicates that disposal took place over four stages in the following order of formation: the first disposal layer, the construction of the first stone-lined tomb, the damage and exposure of the first stone-lined tomb, and formation of the second disposal layer. In particular, it was estimated that the cause of the second disposal event was the clearing of the site related to the reconstruction of Jeseoksa Temple site. The scientific analysis results of the excavated artifacts demonstrate that the second instance of heating had been caused by a fire rather than a kiln. Finally, the study reviewed similar cases from home and abroad and found that similar acts of disposal took place according to emerging needs in an irregular fashion.

일제강점기 고분 조사자료의 검토, 그리고 활용 - 백제 왕릉 최신 재조사 성과와 비교하여 -

김환희 ( Kim Hwanhee ) 국립중앙박물관 2022 고고학지 Vol.28 No.0

일제강점기에 고적조사사업의 명목으로 진행된 공주 무녕왕릉과 왕릉원 및 부여 왕릉원의 조사는 백제 웅진~사비기 왕릉원의 본격적인 첫 조사라는 점에서 의미가 있다. 당시 조사는 짧은 기간에 체계적으로 이루어지지 못하여 소략한 기록만이 남아 있지만, 당시 현황을 파악할 수 있는 가장 직접적인 기초자료로써 중요하다. 최근에는 일제강점기에 진행된 백제 고분 조사자료의 재보고 작업이 진행되고 있는데, 이는 기존의 자료를 재검토하고 분석하여 당시 유적의 모습을 보완하고 복원하는 중요한 접근이 된다. 최근 진행된 공주 무령왕릉과 왕릉원 29호분과 부여 왕릉원 4호분의 재조사에서도 사전조사 단계에서부터 일제강점기 조사기록이 활용되었다. 도면과 사진자료를 통해 고분의 대략적인 위치와 규모 등을 추정하고, 이를 현재 수치지형도 및 항공사진과의 정합 과정을 거쳐 고분의 정확한 위치와 규모를 특정하였다. 또한 발굴조사 단계에서도 조사내용의 검토를 통해 조사 방법과 방향을 설정하는데 활용된다. 이는 과거의 조사에서 누락된 부분과 조사가 진행되지 않은 부분을 빠르게 인지하여 현 단계에서 보완 조사를 추진할 수 있는 중요한 자료가 된다. 일제강점기 자료는 발굴조사 전 단계에 걸쳐 긍정적으로 활용될 수 있기 때문에 성공적인 재조사를 위해 일제강점기 조사기록을 적극적으로 활용할 필요가 있다. The investigations of the Tomb of King Muryeong(the Tomb of King Muryŏng) and the Royal Tombs in Gongju and the Royal Tombs in Buyeo(Buyŏ), which were carried out as part of the Joseon Historical Remains Survey Project undertaken during the Japanese occupation period, are significant in that it they represented the first full-fledged investigations of Baekje(Baekche) royal tombs of the Ungjin and Sabi periods. Although only a small number of records remain, as systematic investigations could not be carried out due to the short length of time, they can still be regarded as the most direct material for understanding the situation of the time. The re-reporting of survey data on ancient Baekje(Baekche) tombs obtained during the Japanese occupation period has taken place recently. This is an important endeavor, in which the re-examination and analysis of existing data can be used as reference in restoring the appearance of tomb remains during the Japanese occupation period. The survey records from the Japanese occupation period were used from the pre-investigation stage when undertaking the recent re-investigations of the Tomb of King Muryeong(the Tomb of King Muryŏng), Tomb No. 29 among the Royal Tombs in Buyeo(Buyŏ), and Tomb No. 4 among the Royal Tombs in Buyeo(Buyŏ). The approximate location and size of the tomb mounds were estimated through drawings and photographic data, and the exact location and size of the mounds were specified by matching them with the data from current numerical topographic maps and aerial imagery. In addition, even during the excavation stage, the survey records were used to set the methods and direction of investigation. The survey records act as an important resource for quickly recognizing what was overlooked during investigations in the past, as well as for identifying areas what were not investigated in the past, thereby making it possible to carry out supplementary investigations at this stage. The fact that data from the Japanese occupation period can be used in such a positive and productive way throughout the pre-excavation phase demonstrates that it is necessary to leave behind negative views and actively use the survey records from the Japanese occupation period to ensure the successful completion of the re-investigations that are again underway.

미디어가 재현하는 가상의 친족으로서 공동체 가족과 청년 담론의 재생산 : 텔레비전 다큐멘터리 서사분석을 중심으로

김환희(Hwanhee Kim) 한국언론학회 2022 한국언론학보 Vol.66 No.3

The discursive struggle over diverse family structures that is seen in current society questions the range and the definition of the typical notion of family and makes people think about new forms of communal life. This study conceptualizes community family, which is a type of a ‘non-typical’ family, based on the fictive kin theory by analyzing the narrative of eight television documentaries that have been aired in South Korea since 2010. The subjects of the documentary that depicts community family are all youths who share generational problems and values, and they form fluid solidarity by sharing mental and material resources with each other. The text utilized a variety of narrative strategies: providing contrast and harmony among the characters, adopting a narrative structure that omits the exploration and the analysis of the causes of a problem, and illustrating only the hopeful image of a community family. Respectively, the generational problem that should be discussed at the socio-structural level became the sole responsibility of the youth and community family was only the second-best option for individuals to respond to the neo-liberal era. In particular, the reproduction of the idealized and romanticized discourse of the youth devalued the seriousness of the structural problem that lies beneath. Korean documentaries have featured community family that seemed to support the discourse of family flexibility. However, the community family’s function and meaning were evaluated against the normality of the typical notion of family. Due to the narrative that shifts the responsibility to the individual youth and emphasizes the romanticism of the community, the possibility of the community family at morphological and practical levels showed realistic limitations. This context of reproduction is not only limited to the community family of the youth but could also exist in the reproduction of any kind of ‘non-typical’ family. Interpretating these multilayered discourses allows us to step closer to the inherent symbolic meaning of the subjects that are being represented by the media, such as the community family.

This study is aimed at articulating the concept of shared decision-making in medical encounter and to examine the factors influencing doctor-patient communication as a two-way symmetrical communication process. To this end, chronic kidney disease was selected as a case requiring shared decision-making, and FGI was conducted for 20 patients undergoing kidney dialysis. Three research questions were posed. First, how is the difference in communication among patients according to the kidney dialysis modality? Second, what are the factors that influence doctor-patient communication that patients perceive according to the dialysis modality? Third, what is the difference between doctor-patient communication according to the dialysis modality (hemodialysis, peritoneal dialysis) in the shared decision-making process? Analysis of interviews founds some interesting differences between the patient groups by dialysis modality. It seems that hemodialysis patients tend to choose the dialysis modality in order to avoid or minimize risk factors such as uncertainty and discomfort related to the dialysis method, whereas peritoneal dialysis patients choose the dialysis modality based on the perceived relative advantages of the dialysis method. Hemodialysis patients showed confidence and relief in the management of treatment by medical staff in hospitals, and their ambiguity aversion encountered in medical situations was relatively higher than that of peritoneal dialysis patients. Therefore, it can be said hemodialysis patients are uncertainty avoiders rather than uncertainty tolerators. Hemodialysis patients also showed a relatively lower level of participation in the treatment process by seeking health-related information compared to peritoneal dialysis patients. Both hemodialysis patients and peritoneal dialysis patients showed high trust in doctors. It seems that the doctor is a life companion for the hemodialysis patients since hemodialysis patients visit and see their doctor more frequently and a daily supervisor for the peritoneal dialysis patients who seldom visit and see their doctor. In addition, patients pointed out some communication limitations such as a lack of sufficient communication for decision making of treatment choice, the limited quantity and quality of information provided by the physician, and channel deficiency to obtain dialysis-related information other than medical staff. This study has academic significance in that it provides a blueprint for facilitating patient-centered communication in medical encounters by linking the meaning of shared decision-making based on two-way symmetrical communication between doctors and patients. In the future, by applying various implications from this study to the issues that require shared decision-making in medical encounters, efforts to practice symmetrical communication between doctors, patients, and society should be extended.
