This experiment was earned out with $^32$P labeled phosphate and lime to determine the optimum amount of phosphate and lime fertilizers to soybean under various types of soil. The determination was made by the index of absorption of phosphate by soybean plants. The index of phosphate was 854 (mg/100g) in non matured soil. Due to the capability of neutralization of calcium the PH of the soil was raised to 6.5. The highest yield was obtained in matured soil at the index of phosphate absorption at 5% level. The degree of contribution of phosphate in. non matured soil showed slightly higher tendancy than that in matured soil.

본 연구에서는 초음파 영상에서 간실질의 에코 명도분포를 분석하여 정량화 지방간 진단 파라미터인 규준화 에코 명도값을 추출하여 지방간의 진행 정도와의 상관성을 연구하였다. 임상 지방간지수와 본 연구의 규준화 에코 명도 값과의 선형 상관 계수를 구하였다. 신장대조 및 간문맥구조에서 추출한 규준화 에코 명도를 계산하여 비교한 결과, 임상 지방간지수와 높은 상관성을 보임을 알 수 있었고, 지방간 진단의 보조자료로 유용함을 확인하였다. 계산된 지방간지수와 상대명도의 선형상관계수는 0.69~0.79이다.

This study aims to investigate not only printed books of Great Learn(大學) published in Chosun dynasty but also existing records concerned with it as well as analyze them typically and systematically. totally 18 kinds of book of Great Learn still remain. Among them 13 kinds of book are written in Chinese(漢文本) and 5 kinds of book are written In Korean(諺解本).

This study was carried out to determine the effect of raising seedling at Hallasan area of sub-alpine (altitude of 600m above sea level) to improve fruiting.ate of Squash (Cucurbita maxima) in retarding culture. 'Ebis' cultivar was seeded in plug tray of 32 cells and the seedlings were grown for 25 days. They were transplanted on August 26, 2004, following L-stem training method under rain-shielding condition. Seedling height, number of nodes and leaf area were higher in lowland than in sub-alpine area. T/R ratio of seedling in sub-alpine was much lower as compared with that in the lowland. The first fruiting was on the 19th node in sub-alpine area, and on the 26th node in the lowland area(control). The succeeding fruiting nodes were lower by 3 to 5 node than those of control. Fruiting rate of second flower was improved by 17.2% compared with the 1.4% in control. The marketable yield was increased by 27% by raising seedling in sub-alpine area (4,460 kg/10a). This also brought out 20% labour saving effect. The environmental condition for raising seedling in the sub-alpine area of Hallasan was effective for the improvement of Squash (Cucurbita maxima) fruiting rate compared with lowland area.

본 연구에서는 임상적으로 얻어진 95개의 영상 자료를 전산화하여 특정 간 영역의 명도분포를 분석하여 이와 간의 지방화 정도와의 상관성을 연구하였다. 지방화 정도를 판단하는 임상적 기준으로 보편적으로 인정되는 지방간지수와 계산된 평균 명도 수치와의 선형 상관 계수를 구하였다. 각각의 영상의 밝기 및 에코정도가 일반적으로 불균일하기 때문에 이를 보정하기 위해 밝은 명도와 어두운 명도의 기준영역을 선정하여 상대명도를 추출하였다. 두 가지 독립적인 방법으로 기준 영역을 선택하여 비교한 결과, 임상 지방간지수와 높은 상관성을 보임을 알 수 있었고, 지방간 진단의 보조자료로 유용함을 확인하였다. 계산된 지방간지수와 상대명도의 상관계수는 0.69 에서 0.79로 나타났다.

This study aimed to figure out the numbers and note distributions and sexagenary cycles of old pyeongyoungs systematically, and estimate the nominal frequency of whangjongeum, the Korean tradition pitch standard. As a total 214 old stones in the National Palace Museum, the National Kukak Center, the Kukak National High School were counted by notes and sexagenaries. The nominal frequencies of 17 old whangjong stones' sounds were categorized by cluster analysis method. Using nominal frequencies of stones according to their sexagenaries and Korean traditional intonation were used to estimate the nominal frequencies of the whangjong. The nominal frequency can be estimated by 22 Keychuk stones as 266.9 Hz, by Cheongyu and Gabja stones as 262.4~262.5 Hz, and by Gabjin, Sowha 12 and Sowha 13 as Estimating by 22 Kyechuk stones which were matched with the records. These results seem to be more reliable, because it is based on the whol samples of old pyeongyoungs, while the former studies have been based on couples of whangjong stones' sounds.
