Hellman 치령(齒齡) IVA 정상인(正常人)에 관(關)한 두부방사선학적(頭部放射線學的) 연구(硏究)
이동주,Lee, Dong Joo 대한치과교정학회 1979 대한치과교정학회지 Vol.9 No.1
This study was undertaken to establish the cephalometric standard of Hellman dental age IVA group of Korean. The subjects consisted of 40 males and 44 females with normal occlusion and aceptable profile. The results were obtained. 1) The tables of standard deviation from the measurements were made. 2) All linear measurement was greater in male than in female. 3) Female had more convex profile than male, 4) Facial convexity, upper and lower lip of esthetic line were gradually decreased with. age. 5) Upper incisor was gradually labioversioned with age.

Disposable, amperometric glucose sensor was constructed using platinised carbon paste electrode. The sensor response was studied by amperometry and cyclic voltammetry applying sample solutions on the strip-type electrode. Platinization of screen-printed carbon paste electrode effectively improved the electrochemical reversibility of a mediator and the analytical characteristics of the sensor. The heterogeneous rate constant for $[Fe(CN)_6]^{4-/3-}$ was $1.45\times10^{-2}cm{\cdot}s^{-1}$. An applied potential of 0.3V vs. Ag/AgCl resulted in the best selectivity for glucose. The apparent Michaelis-Menten constant for glucose on the strip sensor, $K_m^{app}$, was 24.5 mM. To evaluate the analytical performance of the glucose sensor strip, a correlation study was performed with the NOVA S.P, Ultra M analyzer for 30 serum samples containing $80\~297mg/dL$ of glucose: the correlation coefficient value was 0.983. It can be seen that the strip sensor has satisfactory precision and accuracy.

The purpose of this study was to estimate the principal water quality pollution sources at the Jeon-Ju stream using PCA(Principal Component Analysis). All together, eight water quality factors (temperature, pH, DO, BOD, COD, SS, T-N, and T-P) 1984 ~ 1990 of Jeollabukdo Institude of Health & Environment Research were used by PCA and varimax factor rotation tool. The PCA assess three principal factors; relatively highly factor(HF), medium factor (MF), and less factor(LF). The result of application for water quality factors as follows. The HF(T-N) was 50.3%, MF(SS) was 17.7%, and LF(COD) was 13.3%. For water quality stations, the HF(Lee-sung bo), MF(Jeon-Ju stream 6) and LF(Jeon-Ju stream 5) were estimated to be 84.38%, 8.73% and 4.55%, respectively. The result of application for water quality factors and observing stations, the form of the principal factors shows grouping according to factors axis. According to this phenomenon, It was considered that principal component was response to results by PCA. The result of this study is demonstrated that PCA is very effective tool of analysis and interpreation for multi-water quality parameter and multi-station data sets.

The gross domestic product(GDP) measures the welfare of a nation’s economy through the aggregation of products and services produced in a nation. Although GDP is a proficient measure of the magnitude of the economy, many economists, environmentalists, and citizens have recently criticized the gross domestic product. The criticism stems from the fact that this measurement of domestic product does not account for environmental degradation and resource depletion. We need to estimate the environmentally adjusted net domestic product. The gross domestic product was 913 trillion won while environmental protection expenditure was 32.9 trillion won by monetary accounts of Korea, 2010. Loss of natural assets was 76.6 trillion emwon by emergy analysis of Korea, 2010. The Green GDP was accounted for 88.0% of the GDP to 803.5 trillion won.

동궁은 차기 왕위 계승자인 태자가 거처하는 독립된 영역이자 전각을 이르는 말이다. 신라의 동궁은 문무왕 19년에 창조되었다. 유교적 예제와 관련하여 장자상속을 공고히 하려는 조치로 보인다. 그간 동궁의 영역을 월지 일대로 보는 데는 이견이 없었다. 그런데 발굴조사가 진전됨에 따라 임해전을 동궁이 아니라고 하거나 경주박물관 남측 부지에 비정하는 견해가 제출되었다. 임해전은 온실전에 비견되는 국왕의 영역이므로 동궁이 될 수 없다. 그런데 동궁 산하의 관부 가운데 월지악전, 월지전이 배치된 것을 보면 동궁은 월지 일대에 있었던 것은 분명하다. 이와 관련하여 월지 동편 일대의 발굴 성과가 주목된다. (가) 지구에서는 月臺를 갖춘 건물지 2동이 확인되었다. 1호 건물지로 명명된 공간은 담장으로 격절 되어 있다. 궁역의 모퉁이에 위치하고 있으므로 186번 목간에 보이는 ‘隅宮’으로 볼 수 있다. 그리고 7호 건물지 남서편 (나) 지구로 이어지는 공간에 月臺 일부가 노출되어 있다. (나) 지구의 발굴이 이루어지면 그 면모가 드러나겠지만, 이 건물은 1호 건물의 규모를 압도하는 가장 권위적인 공간이다. 따라서 태자가 정무를 보면서 후계자 교육을 받는 공적 공간일 가능성이 높다. 동궁의 범위는 동편은 남북 대로에 의해 구획되며 출입시설로 동문이 조영되어 있다. 서편은 월지와 건물군 사이를 격절하는 담장으로 구획되었을 것이고, 월지 방면으로 소통하기 위한 서문이 조영되었을 것이다. 그리고 남편은 (나) 지구의 월대를 갖춘 건물 앞까지로 추정된다. 북편은 발천이 자연 경계면을 형성하며, 그리 멀지 않은 공간에 흥륜사-황룡사로 이어지는 도로가 조영되었을 가능성이 있다. The East Palace (Donggung) refers to an independent area and royal palace where the crown prince, the next successor to the throne, resides. The East Palace of the Silla Dynasty was established in the 19<SUP>th</SUP> year of King Munmu’s reign. It seems to be a measure for strengthening primogeniture, concerning the Confucian ritual protocol. Until now, there has been no opinion against the consideration of the Wolji Pond area as the East Palace area. And yet, with the progress of the investigation and excavation, some had an opinion that Imhaejeon might not be the East Palace or that it was located at the southern site of the Gyeongju National Museum. Imhaejeon is the King’s realm compared to Onsiljeon. From the placement of Woljiakjeon and Woljijeon of the government departments under the East Palace, it is certain that the East Palace was in the Wolji Pond area. Concerning this, the result of excavation at the east side of Wolji Pond attracts attention. In District Ga(가), two Woldae-style building sites were found. The space named Building Site No. 1 is isolated by the wall. Since it is located at the corner of the palace district, it is assumed to be ‘Ugung Palace’ seen in Wooden Tablet No. 186. Also, in the space connected to District B, part of Woldae is exposed on the south side of Building Site No. 7. If District Na(나) is excavated, the appearance would be revealed, but this building is the most authoritative space that overwhelm the scale of Building No. 1. On the east side of Wolji Pond, this building is very likely to be the public space where the crown prince receives successor education, managing political affairs. As for the scope of the East Palace, the east side is partitioned by Nambuk-daero, and the west side is partitioned by the fence built on the Wolji Pond. The south side is assumed to be in front of the building with the Woldae District Na(나) reaches. It is hard to know the northern border, Balcheon is the border, and it is possible that the road leading to Heungryunsa Temple-Hwangnyongsa Temple was constructed in a not far space.
