In this paper, I examined what have been researched and determined about preservation strategy and selection of preservation media in the western archival community. Archivists have primarily been concerned with 'preservation' and 'use' of archival materials worth of being preserved permanently. In the new information era, preservation and use of archival materials were faced with new challenge. Life expectancy of paper records was shortened due to acidification and brittleness of the modem papers. Also emergence of information technology affects the traditional way of preservation and use of archival materials. User expectations are becoming so high technology-oriented and so complicated as to make archivists act like information managers using computer technology rather than traditional archival handicraft. Preservation strategy plays an important role in archival management as well as information management. For a cost-effective management of archives and archival institutions, preservation strategy is a must. The preservation strategy encompasses all aspects of archival preservation process and practices, from selection of archives, appraisal, inventorying, arrangement, description, conservation, microfilming or digitization, archival buildings, and access service. Those archival functions should be considered in their relations to each other to ensure proper preservation of archival materials. In the integrated preservation strategy, 'preservation' and 'use' should be combined and fulfilled without sacrificing the other. Preservation strategy planning is essential to determine the policies of archives to preserve their holdings safe and provide people with a maximum access in most effective ways. Preservation microfilming is to ensure permanent preservation of information held in important archival materials. To do this, a detailed standardization has been developed to guarantee the permanence of microfilm as well as its product quality. Silver gelatin film can last up to 500 years in the optimum storage environment and the most viable option for permanent preservation media. ISO and ANIS developed such standards for the quality of microfilms and microfilming technology. Preservation microfilming guidelines was also developed to ensure effective archival management and picture quality of microfilms. It is essential to assess the need of preservation microfilming. Limit in resources always put a restraint on preservation management. Appraisal (and selection) of what to be preserved was the most important part of preservation microfilming. In addition, microfilms with standard quality can be scanned to produce quality digital images for instant use through internet. As information technology develops, archivists began to utilize information technology to make preservation easier and more economical, and to promote use of archival materials through computer communication network. Digitization was introduced to provide easy and universal access to unique archives, and its large capacity of preserving archival data seems very promising. However, digitization, i.e., transferring images of records to electronic codes, still, needs to be standardized. Digitized data are electronic records, and st present electronic records are very unstable and not to be preserved permanently. Digital media including optical disks materials have not been proved as reliable media for permanent preservation. Due to their chemical coating and physical character using light, they are not stable and can be preserved at best 100 years in the optimum storage environment. Most CD-R can last only 20 years. Furthermore, obsolescence of hardware and software makes hard to reproduce digital images made from earlier versions. Even if when reformatting is possible, the cost of refreshing or upgrading of digital images is very expensive and the very process has to be done at least every five to ten years. No standard for this obsolescence of hardware and software has come into being yet. In short, digital permanence is not a fact, but remains to be uncertain possibility. Archivists must consider in their preservation planning both risk of introducing new technology and promising possibility of new technology at the same time. In planning digitization of historical materials, archivists should incorporate planning for maintaining digitized images and reformatting them in the coming generations of new applications. Without the comprehensive planning, future use of the expensive digital images will become unavailable. And that is a loss of information, and a final failure of both 'preservation' and 'use' of archival materials. As peter Adelstein said, it is wise to be conservative when considerations of conservations are involved.

창덕궁 후원은 조선시대 궁궐 정원문화의 정수를 보여주는 중요한 공간이다. 후원의 경관체험에 있어서 동선의 복원은 주요 공간을 연결하는 체계를 완성하는 것이다. 그러므로 동선의 복원을 위해서는 생성과 소멸, 유지 등을 정확하게 파악해야한다. 본 연구는 조선 후기에서 근현대 시기까지 문헌과 도면자료 분석과 현장조사를 병행함으로써 창덕궁 후원에서 발생한 동선의 변화를 세밀하게 밝히는데, 그 목적을 두었다. 시계열적인 분석을 위해 조선시대 제작된 「동궐도」, 「동궐도형」와 함께 근현대시기 제작된 「창덕궁평면도」, 항공사진을 사용하였다. 시대별 동선의 변화를 중첩하여 변화를 비교하기 위해 각기 다른 좌표체계로 이루어진 도면과 사진을 지리정보시스템인 ArcGIS에서 하나의 좌표계로 변환하여 정합하였다. 연구 결과는 다음과 같다. 첫째, 일제강점기 이후 총 37개의 구간이 이용되었으며, 이 중에서 13개가 유지되고, 14개가 사라졌으며, 10개가 신설된 것을 확인하였다. 멸실구간 중에서도 능허정 북쪽 원로는 후원에 대한 공간을 연결하고 경관의 향유를 위해 시급히 회복시켜야 할 곳으로 판단된다. 신설구간에서도 대보단지~옥류천 구간에 대해서는 대체동선의 신설이나 구간의 단축 등을 통해서 영향을 최소화할 필요성이 있는 것으로 보인다. 둘째, 후원에서 동선체계에 대한 변화가 가장 크고 빈번하게 시행된 것이 일제강점기와 1970년대 보수정화사업 이었음을 밝혔다. 후원에 대한 주체적 관리가 어려웠던 일제강점기보다 1970년대 이후 발생한 동선의 변화에 대해 주목할 필요가 있다. 옥류천 진입로는 1990년대까지 원형의 모습을 유지하고 있었으나 잘못된 원형 인식으로 인해 현재의 모습으로 정비되었다. 이 시기의 변화에 대해 명확한 기제와 원인을 찾고, 훼손된 원형을 복원하기 위한 사업의 전개가 필요하다. 본 연구는 근현대기 창덕궁 후원 동선 변화를 시대별로 밝혔다는 점이 가장 큰 성과이다. 다만, 조경계획이나 정비에 대한 자료를 찾지 못해 복원해야 할 위치와 형상을 명확하게 제시 못했다는 한계가 있다. 본 연구에서 밝힌 자료를 이용해서 동선을 복원하기 위해서는 현재의 공간 이용도, 관람체계, 방재 및 유지관리 등에 대한 현실적인 문제를 고려해야 할 것으로 보인다.

서울 송현동에 역사문화공원과 이건희 기증관이 조성될 예정이다. 송현동의 역사성은 조선 시대부터 현대까지 정치적 판도에 영향을 받은 시련의 땅으로 인식되었다. 하지만 장소성 분석은 역사적 맥락보다는 토지소유자와 용도 변화에 국한해서 다루어졌다. 그래서 본 연구는 현대문화지리학과 비교역사학 관점을 활용하여 송현동의 장소성이 문화 헤게모니에 따라 변화한 맥락을 분석하였다. 분석결과, 역사적 이행과정에서 나타나는 중화주의, 대항해, 시민혁명, 제국주의, 민족자결주의, 민족주의, 대중예술, 신자유주의 같은 범세계 차원의 문화 헤게모니는 송현동을 비롯한 북촌 일대에 새로운 지식인층을 만들어냈고, 사회제도와 공간정책에 영향을 미쳤다. 이러한 사회적 관계 속에서 송현동의 장소성은 다음과 같이 변화했다. 첫째, 송현의 소나무숲은 이상적인 유교 국가를 목표로 했던 조선 건국세력이 왕조의 영속을 기원하며 만든 비보숲이었고, 내사산의 지맥을 보호하는 사산금표제로 관리되었다. 세계적으로 대항해시대를 맞이한 조선 후기에는 연행이 늘며 청나라 문화를 향유하는 경화세족의 정원이 들어섰다. 일제 강점기에 인구가 급증하면서 주택단지개발로 소나무 숲과 정원은 사라졌지만, 인공적인 정원과 외부의 자연을 조화롭게 연결했던 차경의 경관적 미학은 현대적으로 재해석할 가치가 있다. 둘째, 세계의 근대화 물결은 북촌 일대에 신식학교를, 친일파 소유의 송현동에는 하숙집을 만들었다. 송현동 옆의 안국동천길은 시민혁명과 민족자결주의를 접한 사상가들이 교류했던 장소였고, 최대규모의 하숙집이었던 송현동은 학생들이 3.1운동에 참여하며 학생운동문화가 발아한 계기가 되었다. 안국동천길은 옛길의 모습이 보존되어 있어 광화문-북촌-인사동-돈화문로를 연결하는 역사 도심 보행 재생의 한 부분으로 의의를 지닌다. 셋째, 조선총독부의 문화 통치기부터 군사 정권기까지 송현동은 조선식산은행의 서구식 문화주택과 미국대사관 직원 숙소가 들어서며 서구문화의 통로였다. 주변 지역은 고미술과 현대미술이 공존하며 근현대 미술시장이 형성되었다. 이건희 기증관은 북촌한옥마을, 공예박물관, 현대미술관, 갤러리와 문화벨트를 이루며 시민의 공간으로 변모할 것으로 기대되고 있다. 이같이 장소를 이루었던 숲과 정원, 시민탄생의 거리, 근·현대 미술의 진원지로서 의미가 새롭게 조성될 역사문화공원과 미술관 그리고 주변 보행 네트워크와 조화롭게 재창조될 수 있도록 담론과 도전이 필요하다.

The main purpose of the investigation of an accident caused by aircraft is to be prevented the sudden and casual accidents caused by wilful misconduct and fault from pilots, air traffic controllers, hijack, trouble of engine and machinery of aircraft, turbulence during the bad weather, collision between birds and aircraft, near miss flight by aircrafts etc. It is not the purpose of this activity to apportion blame or liability for offender of aircraft accidents. Accidents to aircraft, especially those involving the general public and their property, are a matter of great concern to the aviation community. The system of international regulation exists to improve safety and minimize, as far as possible, the risk of accidents but when they do occur there is a web of systems and procedures to investigate and respond to them. I would like to trace the general line of regulation from an international source in the Chicago Convention of 1944. Article 26 of the Convention lays down the basic principle for the investigation of the aircraft accident. Where there has been an accident to an aircraft of a contracting state which occurs in the territory of another contracting state and which involves death or serious injury or indicates serious technical defect in the aircraft or air navigation facilities, the state in which the accident occurs must institute an inquiry into the circumstances of the accident. That inquiry will be in accordance, in so far as its law permits, with the procedure which may be recommended from time to time by the International Civil Aviation Organization ICAO). There are very general provisions but they state two essential principles: first, in certain circumstances there must be an investigation, and second, who is to be responsible for undertaking that investigation. The latter is an important point to establish otherwise there could be at least two states claiming jurisdiction on the inquiry. The Chicago Convention also provides that the state where the aircraft is registered is to be given the opportunity to appoint observers to be present at the inquiry and the state holding the inquiry must communicate the report and findings in the matter to that other state. It is worth noting that the Chicago Convention (Article 25) also makes provision for assisting aircraft in distress. Each contracting state undertakes to provide such measures of assistance to aircraft in distress in its territory as it may find practicable and to permit (subject to control by its own authorities) the owner of the aircraft or authorities of the state in which the aircraft is registered, to provide such measures of assistance as may be necessitated by circumstances. Significantly, the undertaking can only be given by contracting state but the duty to provide assistance is not limited to aircraft registered in another contracting state, but presumably any aircraft in distress in the territory of the contracting state. Finally, the Convention envisages further regulations (normally to be produced under the auspices of ICAO). In this case the Convention provides that each contracting state, when undertaking a search for missing aircraft, will collaborate in co-ordinated measures which may be recommended from time to time pursuant to the Convention. Since 1944 further international regulations relating to safety and investigation of accidents have been made, both pursuant to Chicago Convention and, in particular, through the vehicle of the ICAO which has, for example, set up an accident and reporting system. By requiring the reporting of certain accidents and incidents it is building up an information service for the benefit of member states. However, Chicago Convention provides that each contracting state undertakes collaborate in securing the highest practicable degree of uniformity in regulations, standards, procedures and organization in relation to aircraft, personnel, airways and auxiliary services in all matters in which such uniformity will facilitate and improve air navigation. To this end, ICAO is to adopt and amend from time to time, as may be necessary, international standards and recommended practices and procedures dealing with, among other things, aircraft in distress and investigation of accidents. Standards and Recommended Practices for Aircraft Accident Injuries were first adopted by the ICAO Council on 11 April 1951 pursuant to Article 37 of the Chicago Convention on International Civil Aviation and were designated as Annex 13 to the Convention. The Standards Recommended Practices were based on Recommendations of the Accident Investigation Division at its first Session in February 1946 which were further developed at the Second Session of the Division in February 1947. The 2nd Edition (1966), 3rd Edition, (1973), 4th Edition (1976), 5th Edition (1979), 6th Edition (1981), 7th Edition (1988), 8th Edition (1992) of the Annex 13 (Aircraft Accident and Incident Investigation) of the Chicago Convention was amended eight times by the ICAO Council since 1966. Annex 13 sets out in detail the international standards and recommended practices to be adopted by contracting states in dealing with a serious accident to an aircraft of a contracting state occurring in the territory of another contracting state, known as the state of occurrence. It provides, principally, that the state in which the aircraft is registered is to be given the opportunity to appoint an accredited representative to be present at the inquiry conducted by the state in which the serious aircraft accident occurs. Article 26 of the Chicago Convention does not indicate what the accredited representative is to do but Annex 13 amplifies his rights and duties. In particular, the accredited representative participates in the inquiry by visiting the scene of the accident, examining the wreckage, questioning witnesses, having full access to all relevant evidence, receiving copies of all pertinent documents and making submissions in respect of the various elements of the inquiry. The main shortcomings of the present system for aircraft accident investigation are that some contracting sates are not applying Annex 13 within its express terms, although they are contracting states. Further, and much more important in practice, there are many countries which apply the letter of Annex 13 in such a way as to sterilise its spirit. This appears to be due to a number of causes often found in combination. Firstly, the requirements of the local law and of the local procedures are interpreted and applied so as preclude a more efficient investigation under Annex 13 in favour of a legalistic and sterile interpretation of its terms. Sometimes this results from a distrust of the motives of persons and bodies wishing to participate or from commercial or related to matters of liability and bodies. These may be political, commercial or related to matters of liability and insurance. Secondly, there is said to be a conscious desire to conduct the investigation in some contracting states in such a way as to absolve from any possibility of blame the authorities or nationals, whether manufacturers, operators or air traffic controllers, of the country in which the inquiry is held. The EEC has also had an input into accidents and investigations. In particular, a directive was issued in December 1980 encouraging the uniformity of standards within the EEC by means of joint co-operation of accident investigation. The sharing of and assisting with technical facilities and information was considered an important means of achieving these goals. It has since been proposed that a European accident investigation committee should be set up by the EEC (Council Directive 80/1266 of 1 December 1980). After I would like to introduce the summary of the legislation examples and system for aircraft accidents investigation of the United States, the United Kingdom, Canada, Germany, The Netherlands, Sweden, Swiss, New Zealand and Japan, and I am going to mention the present system, regulations and aviation act for the aircraft accident investigation in Korea. Furthermore I would like to point out the shortcomings of the present system and regulations and aviation act for the aircraft accident investigation and then I will suggest my personal opinion on the new and dramatic innovation on the system for aircraft accident investigation in Korea. I propose that it is necessary and desirable for us to make a new legislation or to revise the existing aviation act in order to establish the standing and independent Committee of Aircraft Accident Investigation under the Korean Government.

The study is aimed at exploring concept held by clinical nurses of nursing. The data were collected from 225 nurses conviniently selected from the population of nurses working in Kang Won province. Findings include. 1) Nurse's Qualification. The respondents view that specialized knowledge is more important qualification of the nurse. Than warm personality. Specifically, 92.9% of the respondents indicated specialized knowledge as the most important qualification while only 43.1％ indicated warm personality. 2) On Nursing Profession. The respondents view that nursing profession as health service oriented rather than independent profession specifically. This suggests that nursing profession is not consistentic present health care delivery system nor support nurses working independently. 3) On Clients of Nursing Care The respondents include patients, family and the community residents in the category of nursing care. Specifically, 92.0％ of the respondents view that patient is the client, while only 67.1％ of nursing student and 74.7％ of herself. This indicates the lack of the nurse's recognition toward their clients. 4) On the Priority of Nursing care. Most of the respondents view the clients physical psychological respects as important component of nursing care but not the spiritual ones. Specially, 96.0% of the respondents indicated the physical respects, 93% psychological ones, while 64.1% indicated the spiritual ones. This means the lack of comprehensive conception on nursing aimension. 5) On Nursing Care. 91.6% of the respondents indicated that nursing care is the activity decreasing pain or helping to recover illness, while only 66.2% indicated earring out the physicians medical orders. 6) On Purpose of Nursing Care. 89.8% of the respondents indicated preventing illness and than 76.6% of them decreasing 1;ai of clients. On the other hand, maintaining health has the lowest selection at the degree of 13.8%. This means the lack of nurses' recognition for maintaining health as the most important point. 7) On Knowledge Needed in Nursing Care. Most of the respondents view that the knowledge faced with the spot of nursing care is needed. Specially, 81.3% of the respondents indicated simple curing method and 75.1%, 73.3%, 71.6% each indicated child nursing, maternal nursing and controlling for the communicable disease. On the other hand, knowledge w hick has been neglected in the specialized courses of nursing education, that is, thinking line among com-w unity members, overcoming style against between stress and personal relation in each home, and administration, management have a low selection at the depree of 48.9%,41.875 and 41.3%. 8) On Nursing Idea. The highest degree of selection is that they know themselves rightly, (The mean score measuring distribution was 4.205/5) In the lowest degree,3.016/5 is that devotion is the essential element of nursing, 2.860/5 the religious problems that human beings can not settle, such as a fatal ones, 2,810/5 the nursing profession is worth trying in one's life. This means that the peculiarly essential ideas on the professional sense of value. 9) On Nursing Services. The mean score measuring distribution for the nursing services showed that the inserting of machine air way is 2.132/5, the technique and knowledge for surviving heart-lung resuscitating is 2.892/s, and the preventing air pollution 3.021/5. Specially, 41.1% of the respondents indicated the lack of the replied ratio. 10) On Nurses' Qualifications. The respondents were selected five items as the most important qualifications. Specially, 17.4% of the respondents indicated specialized knowledge, 15.3% the nurses' health, 10.6％ satisfaction for nursing profession, 9.8% the experience need, 9.2% comprehension and cooperation, while warm personality as nursing qualifications have a tendency of being lighted. 11) On the Priority of Nursing Care The respondents were selected three items as the most important component. Most of the respondents view the client's physical, spiritual: economic points as important components of nursing care. They showed each 36.8%, 27.6%, 13.8% while educational ones showed 1.8%. 12) On Purpose of Nursing Care. The respondents were selected four items as the most important purpose. Specially,29.3% of the respondents indicated curing illness for clients, 21.3% preventing illness for client 17.4% decreasing pain, 15.3% surviving. 13) On the Analysis of Important Nursing Care Ranging from 5 point to 25 point, the nurses' qualification are concentrated at the degree of 95.1%. Ranging from 3 point to 25, the priorities of nursing care are concentrated at the degree of 96.4%. Ranging from 4 point to 16, the purpose of nursing care is concentrated at the degree of 84.0%. 14) The Analysis, of General Characteristics and Facts of Nursing Concept. The correlation between the educational high level and nursing care showed significance. (P < 0.0262). The correction between the educational low level and purpose of nursing care showed significance. (P < 0.002) The correlation between nurses' working yeras and the degree of importance for the purpose of nursing care showed significance (P < 0.0155) Specially, the most affirmative answers were showed from two years to four ones. 15) On Nunes' qualification and its Degree of Importance The correlation between nurses' qualification and its degree of importance showed significance. (r = 0.2172, p< 0.001) 0.005) B. General characteristics of the subjects The mean age of the subject was 39 ; with 38.6% with in the age range of 20-29 ; 52.6% were male; 57.9％ were Schizophrenia; 35.1% were graduated from high school or high school dropouts; 56.l％ were not have any religion; 52.6% were unmarried； 47.4% were first admission; 91.2% were involuntary admission patients. C. Measurement of anxiety variables. 1. Measurement tools of affective anxiety in this study demonstrated high reliability (.854). 2. Measurement tools of somatic anxiety in this study demonstrated high reliability (.920). D. Relationship between the anxiety variables and the general characteristics. 1. Relationship between affective anxiety and general characteristics. 1) The level of female patients were higher than that of the male patient (t = 5.41, p < 0.05). 2) Frequencies of admission were related to affective anxiety, so in the first admission the anxiety level was the highest. (F = 5.50, p < 0.005). 2, Relationship between somatic anxiety and general characteristics. 1) The age range of 30-39 was found to have the highest level of the somatic anxiety. (F = 3.95, p < 0.005). 2) Frequencies of admission were related to the somatic anxiety, so .in first admission the anxiety level was the highest. (F = 9.12, p ＜ 0.005) 0. Analysis of significant anxiety symptoms for nursing intervention. 1. Seven items such as dizziness, mental integration, sweating, restlessness, anxiousness, urinary frequency and insomnia, init. accounted for 96％ of the variation within the first 24 hours after admission. 2.

어떤 클래스에 속한 레코드의 개수가 다른 클래스들에 속한 레코드의 개수보다 매우 많은 경우에, 이 데이터 집합을 '불균형 데이터 집합'이라고 한다. 데이터 분류에 사용되는 많은 기법들은 이러한 불균형 데이터에 대해서 저조한 성능을 보인다. 어떤 기법의 성능을 평가할 때에 적중률뿐만 아니라, 민감도와 특이도도 함께 측정하여야 한다. 고객의 이탈을 예측하는 문제에서 '유지' 레코드가 다수 클래스를 차지하고, '이탈' 레코드는 소수 클래스를 차지한다. 민감도는 실제로 '유지'인 레코드를 '유지'로 예측하는 비율이고, 특이도는 실제로 '이탈'인 레코드를 '이탈'로 예측하는 비율이다. 많은 데이터 마이닝 기법들이 불균형 데이터에 대해서 저조한 성능을 보이는 것은 바로 소수 클래스의 적중률인 특이도가 낮기 때문이다. 불균형 데이터 집합에 대처하는 과거 연구 중에는 소수 클래스를 Oversampling하여 균형 데이터 집합을 생성한 후에 데이터 마이닝 기법을 적용한 연구들이 있다. 이렇게 균형 데이터 집합을 생성하여 예측을 수행하면, 특이도는 다소 향상시킬 수 있으나 그 대신 민감도가 하락하게 된다. 본 연구에서는 민감도는 유지하면서 특이도를 향상시키는 모델을 개발하였다. 개발된 모델은 Support Vector Machine (SVM), 인공신경망(ANN) 그리고 의사결정나무 기법 등으로 구성된 하이브리드 모델로서, Hybrid SVM Model이라고 명명하였다. 구축과정 및 예측과정은 다음과 같다. 원래의 불균형 데이터 집합으로 SVM_I Model과 ANN_I Model을 구축한다. 불균형 데이터 집합으로부터 Oversampling을 하여 균형 데이터 집합을 생성하고, 이것으로 SVM_B Model을 구축한다. SVM_I Model은 민감도에서 우수하고, SVM_B Model은 특이도에서 우수하다. 입력 레코드에 대해서 SVM_I와 SVM_B가 동일한 예측치를 도출하면 그것을 최종 해로 결정한다. SVM_I와 SVM_B가 상이한 예측치를 도출한 레코드에 대해서는 ANN과 의사결정나무의 도움으로 판별 과정을 거쳐서 최종 해를 결정한다. 상이한 예측치를 도출한 레코드에 대해서는, ANN_I의 출력값을 입력속성으로, 실제 이탈 여부를 목표 속성으로 설정하여 의사결정나무 모델을 구축한다. 그 결과 다음과 같은 2개의 판별규칙을 얻었다. 'IF ANN_I output value < 0.285, THEN Final Solution = Retention' 그리고 'IF ANN_I output value ${\geq}0.285$, THEN Final Solution = Churn'이다. 제시되어 있는 규칙의 Threshold 값인 0.285는 본 연구에서 사용한 데이터에 최적화되어 도출된 값이다. 본 연구에서 제시하는 것은 Hybrid SVM Model의 구조이지 특정한 Threshold 값이 아니기 때문에 이 Threshold 값은 대상 데이터에 따라서 얼마든지 변할 수 있다. Hybrid SVM Model의 성능을 UCI Machine Learning Repository에서 제공하는 Churn 데이터 집합을 사용하여 평가하였다. Hybrid SVM Model의 적중률은 91.08%로서 SVM_I Model이나 SVM_B Model의 적중률보다 높았다. Hybrid SVM Model의 민감도는 95.02%이었고, 특이도는 69.24%이었다. SVM_I Model의 민감도는 94.65%이었고, SVM_B Model의 특이도는 67.00%이었다. 그러므로 본 연구에서 개발한 Hybrid SVM Model이 SVM_I Model의 민감도 수준은 유지하면서 SVM_B Model의 특이도보다는 향상된 성능을 보였다.

본 논문의 목적은 무형문화유산 일반전승자의 역할을 주목하면서, 소셜 네트워크 분석을 활용해 무형문화유산 전승공동체의 연결망과 전승활동에서 발생하는 지식 흐름의 구조적 특징을 분석하는 데 있다. 이러한 연구 목적을 이루기 위해 본 논문에서는 연구 대상을 국가무형문화재 종목들 중에서 일반인의 전승활동이 활발한 '아리랑'으로 선정하였다. 아리랑은 오랜 기간 제도권 밖에서 일반대중 활동을 중심으로 자생적으로 전승되었으며, 2015년에 전문전승자 지정 없이 국가무형문화재로 지정된 최초의 사례이다. 현재 아리랑은 약 60여 종, 3,600여 곡에 이르는 것으로 추정된다. 본 논문에서는 이 중에서 전문전승자와 일반전승자의 상호교류가 활발한 향토민요 '정선아리랑'을 중심으로 연구하였다. 소셜 네트워크 분석은 사람과 사람 사이의 관계를 노드(Node)와 링크(Link)로 모델링하여 수치화 통계화 시각화하여 해석하는 방법을 말한다. 이 방법은 전통적으로 사회학에서 사회조직 및 취약계층을 연구하는 데 꾸준히 활용되었다. 최근에는 문헌정보학, 문화콘텐츠학, 경영학 등과 같은 분야에서 연구경향, 시장동향, 조직관리 등을 연구하는 데 이 방법이 활용되고 있다. 이처럼 여러 학문 분야에서 소셜 네트워크 분석을 이용한 연구가 증가하는 추세지만 문화재 분야에서는 관련 연구를 찾아보기가 어렵다. 소셜 네트워크 분석은 크게 3단계, '연결망 모델링', '데이터 수집', '데이터 분석 및 시각화'로 진행된다. 본 논문에서는 첫 번째, 2017년 기준으로 정선아리랑보존회 회원 전체를 조사 대상으로 선정하여 완전한 연결망으로 모델링하였다. 두 번째, 데이터 수집은 보존회 회원 명부를 확보해 2017년 10월 17일 면대면 조사와 2017년 12월 15일 전화 설문조사를 통해 하였다. 세 번째, 데이터 분석은 Netminer 4.0 프로그램을 이용해 중심성 분석, 구조적 등위성 분석, 커뮤니티 분석 등을 주요 지표로 하였다. 본 논문은 기존에 무형문화유산 계보조사에서 소수 사람들의 구술자료에 의존해 파악하던 방식에서 벗어나 객관적이고 계량적인 방법으로 조사할 수 있는 기반을 제공하였다는 점에서 연구 의의가 있다. 그리고 무형문화유산 전승공동체 구성원들의 관계 및 지식 흐름의 구조를 지식지도(2D Spring Map) 형태로 시각화함으로써 추상적인 내용을 직관적으로 파악할 수 있게 했다는 점에서 의미가 있다.
