권오성 한국미학예술학회 2003 美學·藝術學硏究 Vol.17 No.-

In this paper, I examined the golden section and Fibonacci number series in jangdan(rhythmic pattern) of Korean traditional music such as Yeongsanhoesang, Gagok, Sijo. The golden section and Fibonacci number series in western music, architecture and fine arts was already researched. It has often been explained that the golden rule exists in the growth of organism, especially in the existing adjacent and new forms. The combination of the two opposites such as sun and moon, man and woman, positive and negative roles of electric currents, yin and yang has been an important concept of myth and mysticism. The two parts in golden section are not the same. Synergy refers to combination and action, not to the opposites. The general process of formal creation is called the opposite energy, it is so called the dinergy. In Daisy, This opposite energy is a creative energy for the growth of organism. The atmosphere of the sunflower is the same as the daisy flower. The numbers of the adjacent existing form and the new one are so-called the numbers of the summation series. Each numbers of the summation series are the total of the two preceding numbers. That is, such as 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, etc. This is the Fibonacci number series. Whatever number divided by the preceding number of the series is close to 0.618. In Sangyeongsan(上靈山), Jungryeongsan(中靈山), Seryeongsan(細靈山) and Garakdeori(加樂除只) among the pieces of Yeongsanhoesang, one jangdan(長短, rhythmic pattern) are consisted of 20 or 10 beats. One jangdan with 20 beats are played into 6:4:4:6 beats. It can be diminished into 3:2:2:3 beats. This rate shows 3(2:1):2 and its multiple, 6:4. It also shows that 6+4 and 4+6, 3+2 and 2+3 form of symmetric structure, which are similar to a golden section, that is, 2÷3=0.6666 which are close to 0.618. Sangyeongsan is played in M.M ♩=30 and Seryeongsan in M.M ♩=45. Gagok(歌曲) is played by male or female voices and alternatively sung with an Ensemble accompaniment. The music dates back to the 10th century and further from the related literature, which, however, it is not testified throughout the old musical notation. According to the old notations, Sakdaeyeop as presently sung dates back to the early 18th century. Jangdan for Gagok consists of 8(3+5(3+2)) : 8(3+5(3+2)) beats, in total, 16 beats. Sijo(時調, short lyric song) has been sung by the scholar or aristocrats and the elderly. It is classified into Pyeong-sijo, Jireum-sijo, and Saseol-sijo. One jangdan of Pyeong-sijo is consisted of 5, 8, 8, 5, 8 beats, that is, 13(5+8)+21(8+5+8)=34, which conforms to Fibonacci number series. The words "Maeami maepda ulgo" is set to 13 beats, "SSeureurami Sseuda uni" reaches the 21st beat. Korean scholar or aristocrats, they may have applied the golden section and Fibonacci number series to their and music enjoyed such as jeongak(正樂, art music), sijo(時調, short lyric song) and folksongs, thinking of the proportion in nature like flower and tree. More research are needed on this subject.

김호림(Ho-Rim Kim),오준섭(Junseop Oh),도현권(Hyun-Kwon Do),이경진(Kyung-Jin Lee),현익현(Ik-Hyun Hyun),오상실(Sang-Sil Oh),감상규(Sang-Kyu Kam),윤성택(Seong-Taek Yun) 대한자원환경지질학회 2018 자원환경지질 Vol.51 No.1

1993년부터 2015년까지 관측된 제주도 지하수 장기모니터링 관측정(N = 4,835)에서 수집된 지하수 수질자료(N = 21,568)를 기반으로 질산성질소의 시공간적 변동 특성을 평가하였다. 제주도 지하수의 질산성질소 농도의 중앙값은 2.5 mg/L로서 다른 국가나 대륙의 조사 결과에 비해 다소 높거나 유사한 것으로 나타났다. 또한 지하수 용도, 행정구역 및 고도 별로 유의한 차이를 보였다. 특히, 산간 지역에 비해 저지대 해안가에 위치한 농업 및 주거지역에서 농도가 높음을 확인하였다. Mann-Kendall 및 Sen’s slope 분석을 활용한 질산성질소 농도의 추세 분석 결과, 하류 저지 대에 비해 중산간지역에서의 질산성질소 농도 증가 경향이 뚜렷하였다. 제주도 내 토지 피복의 시계열 변화 특성과 결부 지어 보면, 중산간지역의 오염 증가 추세는 농업지역의 확장 등 인위적 활동 증가에 기인한 결과로 판단된다. 반면,기지정된 지하수자원특별관리구역에서는 전반적으로 질산성질소 농도의 감소 경향이 나타났는데, 이는 지하수 관리 측면에서 수질관리를 위한 적극적인 정책이 유효함을 시사한다. 본 연구에서는 제주도 지하수의 질산성질소 오염관리를 위한 적정 방안을 제안한다. The spatio-temporal variations of nitrate concentrations in groundwater of Jeju Island were evaluated by an analysis of time series groundwater quality data (N = 21,568) that were collected from regional groundwater monitoring (number of wells = 4,835) for up to 20 years between 1993 and 2015. The median concentration of NO 3 -N is 2.5 mg/L, which is slightly higher than those reported from regional surveys in other countries. Nitrate concentrations of groundwater in wells tend to significantly vary according to different water usage (of the well), administrative districts, and topographic elevations: nitrate level is higher in low-lying agricultural and residential areas than those in high mountainous areas. The Mann-Kendall trend test and Sen’s slope analysis show that nitrate concentration in mid-mountainous areas tends to increase, possibly due to the expansion of agricultural areas toward highland. On the other hand, nitrate concentrations in the Specially Designated Groundwater Quality Protection Zones show the temporally decreasing trend, which implies the efficiency of groundwater management actions in Jeju. Proper measures for sustainable groundwater quality management are suggested in this study.

The main purpose of the study is to develop a computer program in the personal computer which calculates numerically the inflow from the rainfall and displays the inflow hydrograph on a CRT. The computer programs, which were developed for the inflow forecasting of the short-range, employed the storage function method. The program which computes the inflow from the rainfall would be applicable effectively both to planning the daily/weekly power generation and to operating the dam for the flood control. The inflow calculated by the computer program gave a good agreement with the actual inflow for the Choon Chun and the Cheong Pyung dam.

The purpose of this study was to establish Korean normas that will be valuable aids for diagnosis in orthognathic surgery patients. Lateral cephalometric measurements were established for adult Koreans (60 males, 62 females) with normal occlusion and acceptable profiles. The results were as follows: 1. Means, standard deviation and sexual differentiation were included within each measurement. 2. In skeletal mesurements, FH to SN and SN to mandibular plane measurements in females were larger than those in males while all linear measurements in males were larger than those in males were larger than those in females. 3. Significant differences were observed between male and female groups on all of the items that showed vertical relationship in dental measurments. And the measurements of ADH, PDH and overbite in males were larger than those in females while the measurements of incisor exposure in females were larger than those in males. 4. In all measurements of soft tissue except NLA, that is, of FCA, UFH, ULL and LLL, males were larger than those in females.

The formation of charge transfer complex between iodine and aniline in CHCl₃CHCl₄: CH₂Cl₂(1:1), CH₂Cl₂have been studied kinetically by using conductivity method. The initially formed outer charge transfer complex was transformed into a inner charge transfer complex. The pseudo first order rate constants and activation entropy are affected by solvent dielectric constant. The second order rate constants for the decomposition of the outer charge tranfer complex (first order in aniline and in the outer charge transfer complex) depend on the aniline concentration. The ease with which the transfermation proceeds depends on the relative magnitudes of the enthalpy of formation of the outer charge transfer complex as well as aniline concentration.
