감은사는 문무왕대에 시창하여 신문왕 2년(682)에 완공된 신라중대의 불교사원이다. 본 연구는, 기존의 감은사지 발굴조사 성과를 기초로 하고, 역사학 분야 등에서의 문헌연구 성과를 참고로 하여, 신라감은사건축의 조영계획 양상 및 특질, 그리고 그것과 당시의 정치·사회적, 종교적 환경 간의 관계에 대한 구명을 시도한 것이다. 연구 결과는 다음과 같다. (1) 감은사 중심곽 내 당탑 및 회랑, 중문과 강당 등 모든 건축물은, 기단부를 기준하여, 방(方)216척(尺)(고구려척, 추정단 위치수 353.30mm)의 윤곽에 남거나 부족함 없이 정확하게 들어가는 것으로 확인된다. 이러한 사실은, '만파식적설화'와 유교예악사상과의 관계, '이견대'의 명칭과 『주역』과의 관계, '감은사지출토 태극무늬장대석'과 『주역』과의 관계 등으로부터 확인되는, 동해구 유적(대왕암·이견대·감은사)에 서린 신라중대왕실의 '유교정치이념의 표방' 의지에 비추어 볼 때 매우 유의미한 것으로 판단되며, 감은사가람의 설계초기단계에 있어서, 잠재하는 규모계획의 기준으로부터 이차적 조정으로서, 『주역』 계사상의 '건지책 216'으로부터 수를 취해 가람중심곽규모의 결정기준으로 삼은 결과로 추정된다. 감은사 당탑 등의 배치계획은, 방(方)216척(尺)의 윤곽 내, 가장자리로부터 중심부로, 즉 가람중축선상 중문·강당의 배치 및 금당 남북위치의 결정, (중문·강당·금당 측면에 각각) 남회랑·강당동서편건물·익랑 배치, 동서회랑의 배치, 동서 석탑 중심위치 결정의 순으로 진행되었을 것으로 추찰된다. (2) 감은사건축에 있어서의 유불공존적 양상은, 『금광명경(金光明經)』에 대한 이해를 바탕으로 한 것이며, 왕의 화신인 용이 용혈(龍穴)을 통해 금당기단 내에 들어 선요(旋繞) 즉, 공경·숭봉(崇奉)을 행함으로써 "음양조화시부월서(陰陽調和時不越序) 일월성숙부실상도(日月星宿不失常度) 풍우수시무제재횡(風雨隨時無諸災横)" 등의 무량공덕이 얻어지기를, 그리고 일월에 비유되는 부처의 광명이, 새로이 유교를 정치이념으로 삼아 운영해 나갈 국가, 신라의 사방 천하(천(天)=건(乾), 건지책 216척(尺) 규모의 가람중심곽)에 길이 두루 비춰지기를 염원한 문무왕의 뜻에서 비롯된 것으로 추찰된다. 그리고 그 구상 및 실현에 있어서는 유불습합적 사상 경향을 가졌던, 그리고 문무왕이 유언으로서 국사로 삼기를 당부했고 신문왕 즉위 후 국로로 임명되었던, 경흥(憬興)이 깊이 관여했을 것으로 추측된다.

We conclude the following with air pollution data measured from city measurement net administered and managed in Gwangju for the last 7 years from January in 2001 to December in 2007. In addition, some major statistics governed by Gwangju city and data administered by Gwangju as national official statistics obtained by estimating the amount of national air pollutant emission from National Institute of Environmental Research were used. The results are as follows ; 1. The distribution by main managements of air emission factory is the following ; Gwangju City Hall(67.8%) > Gwangsan District Office(13.6%) > Buk District Office(9.8%) > Seo District Office(5.5%) > Nam District Office(3.0%) > Dong District Office(0.3%) and the distribution by districts of air emission factory ; Buk District(32.8%) > Gwangsan District(22.4%) > Seo District(21.8%) > Nam District(14.9%) > Dong District(8.1%). That by types(Year 2004~2007 average) is also following ; Type 5(45.2%) > Type 4(40.7%) > Type 3(8.6%) > Type 2(3.2%) > Type 1(2.2%) and the most of them are small size of factory, Type 4 and 5. 2. The distribution by districts of the number of car registrations is the following ; Buk District(32.8%) > Gwangsan District(22.4%) > Seo District(21.8%) > Nam District(14.9%) > Dong District(8.1%) and the distribution by use of car fuel in 2001 ; Gasoline(56.3%) > Diesel(30.3%) > LPG(13.4%) > etc.(0.2%). In 2007, there was no ranking change ; Gasoline(47.8%) > Diesel(35.6%) > LPG(16.2%) >etc.(0.4%). The number of gasoline cars increased slightly, but that of diesel and LPG cars increased remarkably. 3. The distribution by items of the amount of air pollutant emission in Gwangju is the following; CO(36.7%) > NOx(32.7%) > VOC(26.7%) > SOx(2.3%) > PM-10(1.5%). The amount of CO and NOx, which are generally generated from cars, is very large percentage among them. 4. The distribution by mean of air pollutant emission(SOx, NOx, CO, VOC, PM-10) of each county for 5 years(2001~2005) is the following ; Buk District(31.0%) > Gwangsan District(28.2%) > Seo District(20.4%) > Nam District(12.5%) > Dong District(7.9%). The amount of air pollutant emission in Buk District, which has the most population, car registrations, and air pollutant emission businesses, was the highest. On the other hand, that of air pollutant emission in Dong District, which has the least population, car registrations, and air pollutant emission businesses, was the least. 5. The average rates of SOx for 5 years(2001~2005) in Gwangju is the following ; Non industrial combustion(59.5%) > Combustion in manufacturing industry(20.4%) > Road transportation(11.4%) > Non-road transportation(3.8%) > Waste disposal(3.7%) > Production process(1.1%). And the distribution of average amount of SOx emission of each county is shown as Gwangsan District(33.3%) > Buk District(28.0%) > Seo District(19.3%) > Nam District(10.2%) > Dong District(9.1%). 6. The distribution of the amount of NOx emission in Gwangju is shown as Road transportation(59.1%) > Non-road transportation(18.9%) > Non industrial combustion(13.3%) > Combustion in manufacturing industry(6.9%) > Waste disposal(1.6%) > Production process(0.1%). And the distribution of the amount of NOx emission from each county is the following ; Buk District(30.7%) > Gwangsan District(28.8%) > Seo District(20.5%) > Nam District(12.2%) > Dong District(7.8%). 7. The distribution of the amount of carbon monoxide emission in Gwangju is shown as Road transportation(82.0%) > Non industrial combustion(10.6%) > Non-road transportation(5.4%) > Combustion in manufacturing industry(1.7%) > Waste disposal(0.3%). And the distribution of the amount of carbon monoxide emission from each county is the following ; Buk District(33.0%) > Seo District(22.3%) > Gwangsan District(21.3%) > Nam District(14.3%) > Dong District(9.1%). 8. The distribution of the amount of Volatile Organic Compound emission in Gwangju is shown as Solvent utilization(69.5%) > Road transportation(19.8%) > Energy storage & transport(4.4%) > Non-road transportation(2.8%) > Waste disposal(2.4%) > Non industrial combustion(0.5%) > Production process(0.4%) > Combustion in manufacturing industry(0.3%). And the distribution of the amount of Volatile Organic Compound emission from each county is the following ; Gwangsan District(36.8%) > Buk District(28.7%) > Seo District(17.8%) > Nam District(10.4%) > Dong District(6.3%). 9. The distribution of the amount of minute dust emission in Gwangju is shown as Road transportation(76.7%) > Non-road transportation(16.3%) > Non industrial combustion(6.1%) > Combustion in manufacturing industry(0.7%) > Waste disposal(0.2%) > Production process(0.1%). And the distribution of the amount of minute dust emission from each county is the following ; Buk District(32.8%) > Gwangsan District(26.0%) > Seo District(19.5%) > Nam District(13.2%) > Dong District(8.5%). 10. According to the major source of emission of each items, that of oxides of sulfur is Non industrial combustion, heating of residence, business and agriculture and stockbreeding. And that of NOx, carbon monoxide, minute dust is Road transportation, emission of cars and two-wheeled vehicles. Also, that of VOC is Solvent utilization emission facilities due to Solvent utilization. 11. The concentration of sulfurous acid gas has been 0.004ppm since 2001 and there has not been no concentration change year by year. It is considered that the use of sulfurous acid gas is now reaching to the stabilization stage. This is found by the facts that the use of fuel is steadily changing from solid or liquid fuel to low sulfur liquid fuel containing very little amount of sulfur element or gas, so that nearly no change in concentration has been shown regularly. 12. Concerning changes of the concentration of throughout time, the concentration of NO has been shown relatively higher than that of $NO_2$ between 6AM~1PM and the concentration of $NO_2$ higher during the other time. The concentration of NOx(NO, $NO_2$) has been relatively high during weekday evenings. This result shows that there is correlation between the concentration of NOx and car traffics as we can see the Road transportation which accounts for 59.1% among the amount of NOx emission. 13. 49.1~61.2% of PM-10 shows PM-2.5 concerning the relationship between PM-10 and PM-2.5 and PM-2.5 among dust accounts for 45.4%~44.5% of PM-10 during March and April which is the lowest rates. This proves that particles of yellow sand that are bigger than the size $2.5\;{\mu}m$ are sent more than those that are smaller from China. This result shows that particles smaller than $2.5\;{\mu}m$ among dust exist much during July~August and December~January and 76.7% of minute dust is proved to be road transportation in Gwangju.
