세종의 음악 정치 목적과 방법 고찰

송혜진 ( Hye Jin Song ) 한국동양예술학회 2012 동양예술 Vol.20 No.-

본고에서는 세종대에 이루어진 여러 가지 음악관련 일들을 ‘음악정치’ 관점에서 재조명하였다. 음악은 감정의 언어로 인간의 감정을 유발, 발산, 정화, 격려하며, 메시지를 전달한다. 감정 언어로서의 음악의 성격은 고대로부터 인지되었다. 그래서 국가가 애써 교육하고 퍼뜨려야 할 음악과, 배격해야 할 음악을 분류하고, 국가의 지도자는 ‘건전한 음악’, ‘교육하기에 적합한 음악’, ‘바른음악’을 알고, 국민들을 ‘바른 음악’의 세계로 이끄는 것을 중히 여겼다. 이처럼 음악을 정치의 목적과 수단을 위해 어떤 음악이 ‘선전(propaganda)’되고 ‘금지’되었다. 이같은 예는 중국의 고전 『樂記』의 예악론에서부터 서양의 근현대사에서 이루어진 다양한 음악정치의 사례까지 무수히 많으며, 관련 연구도 적지 않다. 기존의 연구에서 세종의 음악정책을 예악론과 연관지은 논의는 있었으나 음악정치의 관점에서 세종의 음악정치 역량, 목적, 방법, 평가 등을 고찰한 논저는 없었으므로, 본고에서는 이에 초점을 두었다. 음악정치의 성공여부는 통치자의 음악 이해도와 관계가 깊다. 이 관점에서 볼 때 세종은 음악 소양을 갖추고, 이론적 체계를 공부하였으며, 일상에서 향유할 줄 아는 知音 군주였다. 이를 토대로 세종은 尊卑의 차등이 분명하되 각기 능멸하지 않고 크게 조화를 이룬다는 예악론을 현실에 구현할 수 있었다. 또한 직접 신악을 창제하고, 악보를 창안하였다는 점에서 세종은 음악정치를 주도할만한 역량을 충분히 갖춘 것으로 평가된다. 세종의 음악 정치 목적에 주목해 본 결과, 守成期의 정치상황을 음악으로 풀어보려는 의도가 있었던 것으로 해석된다. 세종은 上下通情의 화합을 도모하고 건국의 명분과 정당성을 펼치는데 관심이 높았다. 세종이 정치의 목적을 담은 歌詞 짓기를 독려하여 수십곡의 樂章이 新制된 점, 여러 곡 중에서 선왕의 공덕을 기리는 내용의 노랫말을 선별하여 가사에 담긴 ‘이야기’를 직접 작곡하여 발표한 일련의 과정들은 세종의 정치적 목적을 뚜렷하게 반영하고 있다. 세종이 택한 음악 정치의 방법은 첫째, 백성들과 교감할 수 있는 음악언어, 즉 향악의 선택, 둘째, 가사에 담긴 내용을 시각적으로 형상화할 수 있는 악가무 종합구성 양식의 선택, 셋째, 전파, 전승을 위한 기록방법 고안, 넷째. 강제적인 선전이 아닌 점진적 교화였다. 세종은 건국 정당성과 선왕의 업적을 기리는 노랫말에 전통적인 예악론에서 중시되는 ‘아악’ 대신 고려 전래의 토속성 강한 향악을 선택하였다. 이는 사람과 지리, 기질, 풍토에 따라 말과 音이 다르다는 점을 간파하고, 백성과 교감하는데 향악의 음악요소가 보다 효율적임을 판단한 결과였다. 세종은 정치적 목적을 담은 가사를 연주와 노래뿐 만 아니라 복식, 儀物을 갖춘 무용수들의 움직임 등이 종합적으로 어우러진 대규모의 작품으로 완성하였다. 이는 단순한 이야기의 전파를 염두에 둔 민요풍의 노래만들기가 아니라, 왕조의 위엄과 권위를 시각적, 청각적으로 공감하게 하는 장치로서 중요한 선택이었다고 판단된다. 한편, 세종은 새로이 제정한 음악을 널리 퍼뜨리기 위해 연주제도를 만들고, 악보를 편찬하는 등의 노력을 기울였다. 그러나 이를 강제로 선전하려는 노력은 하지 않았다. 즉, 음악정치에서 흔히 논의되는 독재자들의 음악정치 선전 양상은 발견되지 않는다.이밖에 세종은 국가의 풍속을 바른 데로 이끈다는 명분으로 불교 및 무속관련 음악을 ‘폐풍’으로 규정, 통제하고, 향락적인 유흥은 금하였다. 그러나 통제의 방법에서도 오래된 풍속이어서 백성들이 알지 못하여 죄를 범하는 일이 없도록 점진적인 방식을 택하도록 하였으며, 예악을 바로 세워야 한다는 원론에는 맞더라도 관습을 참조하여 규제를 유예함으로써 통제가 억압과 독재에 이르는 것을 방지하였음을 밝혔다. 이같은 세종시대의 음악정치는 동시대에는 대내외적으로 예악문물이 중화에 못지않으며 周 시대의 이상을 재현한 것으로 평가 받았고, 후대의 통치자들에게는 예악으로 善政을 펼친 성군으로 인식되고 있다. In politics, music has been exploited as one method used to govern a country. In the ancient document, Akki, "Ye-ak (the formal practice of human ethics and music) is defined as the root ideology used to govern the country, and politics can be comprehended by the understanding of music". Based on various examples related to the exploitation of music in politics in the history of Western society, the notion that "music is political whether fair or foul" has been current for a long time in western society as well. Therefore, the relation between music and politics is surely very close. If we look at aspects of music based on a political view, some music takes on the role of propaganda while other music is prohibited. Also, some musicians use their music to praise somebody or something while others use their music to oppose. Music is a language of emotion. It induces and releases the emotion of human beings. At the same time, it also purifies and encourages people``s emotion, and delivers a message. The characteristics of music as a language of emotion have been recognized from ancient times. Therefore, during the Joseon dynasty, the state assorted music into several various kinds such as music that should be promulgated and distributed, and music that should be rejected. It was regarded as an important matter that the leader of the state understood ``healthy music``, ``music that is suitable for education``, and ``correct music``, and thus guided the people to the realm of ``correct music``. From the early Joseon dynasty, Ye-ak (thought based on Confucianism) was regarded as the basic ideology of society. The realization of politics with human ethics and music was a significant issue since the early years of the dynasty. Therefore, in this period, the organizing and institutionalization of the state``s ceremonial music based on this ideology was a matter of great concern. In particular, during the reign of King Sejong, the degree and extent of effort aimed at achieving this end reached a high point. In this paper, I have re-examined various achievements related to music during the reign of King Sejong based on a political point of view. Sejong was well equipped in this regard, since he had learned about the theory of music and was able to enjoy music in his daily life. With this background, he organized court music, created new musical pieces, and used these pieces in various court ceremonies and parties. There were three purposes for this. First, it was to maintain the Ye-ak concept that is possible to distinguish between the high and the low but at the same time to create harmony between them. The second purpose was to promote accord and good rapport between the high and the low people throughout times of prosperity. The third was to clearly define the justification and legitimacy of the state``s foundation. Numerous songs were created, and performance forms mixing song and dance were selected to express ``stories`` of the songs`` texts in synesthetic metaphor. Such presentations were stylized, and high levels of performances were accomplished with appropriate costumes, accessories and movements. Although Aak, which had been introduced from China and influenced by its music, was used in court music during his time, several elements from native Korean traditional music were also adopted based on Sejong``s understanding that the language and music must be different according to people, geography, tendencies, and natural characteristics. A new system of dissemination was established, and several new score books were published to promulgate achievements. However, no enforced propaganda was carried out. Music and dance related to Buddhism and Shamanism were restricted, and this was justified on the grounds that the state``s custom had to be guided in a correct direction. Also, entertainment merely for pleasure and enjoyment was prohibited. However, enforcement progressed gradually, and several regulations were postponed, and so national control never reached a level of oppression or dictatorship. Such achievements related to the exploitation of music in politics were well evaluated during this time. It was also deemed that the Korean Ye-ak culture was well established, and conducted just as well in Korea as in China, such that it was often compared to the ideal level of the Chu state of China when the Ye-ak ideology had reached its climax. In addition, Sejong has been recognized, even up to now, as a good and wise king who governed the people very well using Ye-ak thought and culture.

치매환자 조호자를 위한 교육지지프로그램의 효과성에 관한 비교연구

Objective:We studied the effect of Hyu-Sig-Gong-Gan and Hye-Ah-Rim on several evaluations and compared the two programs. We then investigated factors associated with the difference between pre- and post-ratings. Methods:Thirty-six patients were randomized to Hyu-Sig-Gong-Gan (n=23) or Hye-Ah-Rim (n=13). We tested for the effect of each program on several evaluations and compared the two programs through Zarit Burden Interview (ZBI), Center for Epidemiologic Studies-Depression Scale, Dementia Attitude Scale (DAS)-intelligence, DAS-comfort and DAS-total. We then investigated whether the difference between pre- and post-rating depends on other factors. Results:We observed significant positive effect of Hyu-Sig-Gong-Gan on DAS-comfort (t=1.843, p=0.039) and significant positive effect of Hye-Ah-Rim on ZBI (t=-2.327, p=0.019), DAS-comfort (t=2.241, p=0.022), and EuroQol-5 Dimensions-Visual Analogue Scale (t=2.537, p=0.013). For comparing the two programs, we found a lack of evidence for the difference in any of the five commonly observed evaluations. In the secondary analysis, we observed a strong trend that the two programs were particularly effective for caregivers with negative pre-ratings. Conclusion:The two programs showed positive effects on the various evaluations, but some evaluations could not reach statistical significance. The programs appear to be particularly helpful for those who are in need before the program participation.

송혜란,김진하,변주현,이광영,이덕희,김호찬 大韓産業醫學會 2003 대한직업환경의학회지 Vol.15 No.3

목적: 전공의는 여러 유해인자에 노출되어지고 있으며 과중한 업무로 인한 수면 부족에 시달리고 있다. 본 연구는 전공의의 건강상태의 기초 자료를 제공하고 향후개선 방안을 도출하기 위하여 시행하였다. 방법: 연구대상은 2000년 3사관학교와 국군군의학교에 입소한 전체 1,316명 중 전공의 수련과정 없이 입대한 의사와 치과의사, 한의사를 제외한 881명을 대상으로 설문지를 배포하여 784부(회수율: 89.0%)를 회수하고 이중 분석이 가능한 704(79.9%)명의 자료를 최종 분석하였다. 결과: 월평균 당진횟수는 레지던트 1년차에서 19회 정도이었다. 당직 시 평균 수면시간은 레지던트 1년차에서 4시간미만 이었다. 수련기간 동안 전공의의 20%이상에서 방사선, 레이저, 살균소독제, 마취가스, 항암제에 노출되었으며 예방대책은 방사선과 레이저의 노출의 경우 35%정도를 제외하고는 10%내외로 조사되었다. 연구대상자중 91.1%에서 수련기간 동안 주사침이나 시술에 의해 손상을 입었으며 그 중 본인이 감염된 경우는 HBV 2.3%(4명), HCV 0.6%(1명)으로 조사되었다. 응답자의 28.4%에서 자신의 직업에 불만족 하였으며 96.5%가 과중한 업무부담을 느꼈고 69.5%가 동일한 임금수준에서 직업을 바꾸고자 한다고 응답하였다. 결론: 전공의는 수련기간 동안 물리적, 화학적, 생물학적 유해인자에 노출되고 있었으나 이에 대한 보호나 예방대책은 거의이루어지지 않고 있었으며 과중한 업무부담으로 수면부족을 초래하여 가장 중요한 환자 진료에 지장을 받고 있었다. 수련기간 동안 대다수가 의사로서 직업에 대한 흥미를 가지고 있었으나 업무부담과 진료이외의 업무 등으로 소득과 조건이 비슷하다면 다른 직업을 선택하고자 하였다. 이상의 결과를 토대로 전공의들을 위한 유해인자의 보호대책 및 예방대책을 마련하며 과중예방대책이 마련되어야 하고 업무환경개선 및 업무로 인한 건강장해에 대한 정당한 보상이 향후에 마련되어야 할 것이다. Objects: Residents are exposed to various hazards and harassed by sleep dificiency due to overwork. This study was performed to outline the health condition of residents and develop the ways of improving it. Mehtods: A questionnaire was distributed to 881 army doctors who enrolled at the Korea Third Military Academy and The Armed force Health Service School in 2000 with the exception of medical doctors who joined the armed service without going through intern and resident periods, dental and oriental medical doctors. 784(89.0%) of the 881 questionnaires were resident of which 704 cases (79.9%). This should actually be 89.0% were regarded for analyses as being reliable data. Results: More than 20% of residents were exposed to radiation, laser, disinfectants, anesthetic gas, and anticancer drugs during their training periods with preventive neasures for each of these hazards taken in about 10% of the cases of the lesser hazards but in about 35% for the hazards from radiation and laser. 91.1% of residents had experience of needlestick injuries during theirtraining periods with over 36.3% being exposed to patients with infection during that time. The cases contracting HBV and HCV diseases due to pricking are 2.3% and 0.6% respectively. The average number of night duties per month during a one-year resident's period was about 10. The average sleeping time on duty during a one-year residents was less than 4 hours. 28.4% of respondents were not satisfied with their occupation, 96.5% delt tired from overwork and 69.5% wanted to change their occupation to another that would pay the same salary. Conclusion: Residents are exposed to harmful physical, chemical and biological factors, but the preventive care seldom undertaken. In addition, their overwork brings about lack of sleep which causes them problems when giving medical treatment to patients during their training periods. Despite the resident's interest in an occupation as a doctor, many intend to select other occupations if they can receive the same salary. According to the above results, preventative systems and measures should be prepared with environmental improvements for residents, and proper rewards for their overwork should be accomplished

Gastrointestinal stromal tumors (GISTs) are common mesenchymal tumors that arise in the wall of the gastrointestinal tract. We report a case of obscure gastrointestinal bleeding due to a GIST of the jejunum successfully documented by videocapsule endoscopy (VCE) and single-balloon enteroscopy (SBE). A 36-year-old man with hematochezia was referred for further evaluation of no evidence of bleeding focus on esophagogastroduodenoscopy and colonoscopy. A VCE showed a suspicious ulcerative hyperemic mass that located in about 1 hour apart from duodenal second portion. SBE revealed a nonbleeding 4×2 cm mass with an ulcer at the proximal jejunum. The patient underwent laparoscopic resection without complication. Histological examination revealed a well circumscribed, dumbbell-shaped firm mass comprised of spindle cells. Immunohistochemical staining for CD 117 was diffusely positive, whereas staining for S-100, CD 34 and MIB-1 was all negative. It was confirmed to be a low-grade GIST at the proximal jejunum.

조혜진,송창훈 朝鮮大學校 附設 醫學硏究所 2004 The Medical Journal of Chosun University Vol.29 No.1

Objective : Fetal adrenal gland hormone was known to have close association with fetal weight and labor pain in response to fetal stress. Our purpose was to analyze the correlation between cord blood hormone (cortisol, DHEA-S) and fetal weight, delivery type, gestational age and other factors(insulin, glucose and IGF-1). Method : We collected cord blood samples from 60 neonates immediately after delivery of baby. Six cases were complicated by intrauterine growth retardation and fourteen patients were complicated by preeclampsia. We measured cortisol, DHEA-S levels by using the RIA commercial Kits for ELISA and insulin, IGF-1 levels by IRMA method and glucose level by Enzyme immunoassay. We performed statistic analysis of the data on the SPSS computer program. Result : 1. Blood cortisol level was significantly higher in intrauterine growth restriction (23. 4±16.2,㎍/dL) statistically than that in control group (13.7±9.5,㎍/dL)(P=0.022). Cortisol and DHEA-S had negative correlation each other(P=0.025). 2. DHEA-S level was significantly lower in intrauterine growth restriction(1202.2±1005.9ng/mL) than that in control group(1714.8±978.6ng/mL) (P=0.01). DHEA-S had increased with advancing gestational age(P=0.03) and fetal weight (P=0). It had negative correlation with cortisol and IGF-1(P=.025, 0.024) respectively. 3. Glucose had positive correlation with cortisol and insulin (P=0.023, 0) and negative correaltion with IGF-1(P=0.043). Conclusion : Cord blood cortisol, DHEA-S, insulin, glucose and IGF-1 have close association with fetal stress during labor. And cortisol, DHEA-S, insulin, glucose and IGF-1 have close association with each other.

Random SVPWM 기법을 이용한 고조파 저감에 관한 연구

權炳徽,元鎭熙,宋榮柱 홍익대학교 산업기술연구소 2002 産業技術 Vol.12 No.-

Typical PWM switching method for a induction motor speed control system causes harmonic currents. Induction motor with the rated current by a space vector or a randomly generated fractional number method has been studied for reducing harmonic currents. This paper presents the fixed switching SVPWM and random SVPWM using Matlab / Simulink and then applies to the induction motor operating system, and proposes through simulations for the speed, the response of torque, the waveform of phase current etc. Consequently, the simulation confirms the output current harmonic cancellation by SVPWM inverter.
