Paddy-field farming in Korea had played a pivotal role of agriculture in the late Yi Dynasty as a result of the development of agricultural technology since the early Yi dynasty. The agricultural system centering paddy-field farming has contined through the present despite an increase in population and the expansion of arable land. The purpose of this study is to find how paddy-field farming has developed regionally. Four main cross-sections,-the early 15th century, the middle 18th century, the early 20th century, the late 20th century-are formulated for this purpose. The ratio of paddy-field area to that of arable land is calculated, which is classified according to Kun and Hyun, to scrutinize the regional distribution of paddy-fields. Also the fluctuation in the proportion of paddy-field between one time cross-section and the following to clear regional differences in the development of paddy-field farming. In this process, the results were showed using cartographic analysis. Considering the proportion of paddy-fields until the early 20 century macroscopically, we can find some difference between the northern region and the southern region of Namhan river. The latter of the south is highier than that of the north. The proportion of north was not high until the late 20 contury. It was the lower reaches of a large river and the lower and middle reaches of a small river that exceed 50% in the proportion of paddy-fields in the early 15th century. Especially, Man Kyeong. Impi, Okgu Hyun in which the proportion was over 70%, was the core region of paddy-field. But, in the case of the northern part of Namhan River, while half of the part had paddy-fields vender 3%, 12 Kuns or Hyuns located in the northern mountain region had no paddyfields. In the middle 18 century, the proportion increased so that the ratio of the south province was largely over 50%. In the early 20th century, the proportion was over 70. In the late 20th century, Kang Won and Chung Buk province was under 50 in the ratio of paddy-field, while the other provinces ranged from 50% to 70%. The proportion by province maintained the level of 40% to 70% as a result of decrease in regional differences in the late 20th century. In addition, the proportion of Honam province showed a 13% increase from the early 15th century to the middle 18th century while the proportion of Chung Cheong province showed a 27 increase, which is the gratest increase since, in the middle 18th century and the early 20th century. In the 20th, Kyong Gi and Kang Won province-especially the northern part of Namhan river-showed a high increase. This increase of paddy-field ratio resulted from the expansion of On-Tap, which was made through reclamation of coastal marsh land, and from the expansion of Pon-Top which was made through change of field to paddy-field. Depending on such regional enlargement procedures of paddy-field farming, Korean agrarian civilization is roughly generalized as a 'long history of paddyfield enlargement'. The procedure has gradually proceeded from Honam region, the hotbed of Korean paddy-field farming, to the northern part. The late Yi Dynasty about 18th century can be regarded as 'the period of agrarian revolution', because it saw the formation of basic framework of paddy-field farming, due to rice and doublecrop transplantation technique in view of farming method-rice and barley. The mid 20th century can be considered as the peak period of traditional agrarian civilization, according to the scale and ratio of nation-wide paddyfield area, and relative importance of agricultural population.

Visualization of Specific Energy for Open Channel Flow in Three Dimensions

이준선,이승오,Donald D. Gray,홍승호 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.6

Specific energy is the total head with respect to the channel bottom. It is a summation of the velocity head and the depth of flow at a given cross section. Specific energy has proven to be very useful in the analysis of open channel flow and the concept is discussed in every open channel book. Usually, the discussion is illustrated by 2-dimensional plots of depth vs. specific energy with discharge as a parameter and/or depth vs. flowrate with specific energy as a parameter. Obviously, these graphs depict slices through a surface in a three-dimensional space whose coordinates are depth, discharge, and specific energy. Furthermore, the plots are almost invariably displayed only for rectangular cross sections, and the three-dimensional specific energy surface is rarely shown. Using graphical software, this paper displayed the specific energy function as a surface in three dimensions for rectangular cross sections. For the first time, the specific energy function is also visualized in three dimensions for rectangular and trapezoidal cross sections as well as a compound channel cross sections, revealing unexpected features. Above all, this study is particularly meaningful in expressing alternate depth and critical water depth in an effective way that only a few researchers have tried to express before.

In this paper purpose is investigate to effects of Hydroponic cultured Ginseng leaf Extract and Kidney function depression in Rheumatoid arthritis Rat model. Rheumatoid arthritis Rat model was used Rat Type Ⅱ Collagen + adjuvant and sequentially injected in tail 7days. Studying animal groups are as follows; GroupⅠ: Control group(n=5), groupⅡ: collagen injected Rat, GroupⅢ: collagen injected + Hydroponic cultured Ginseng leaf Extract 200mg/kg treated Rat, GroupⅣ: collagen injected + Hydroponic cultured Ginseng leaf Extract 100mg/kg treated Rat, GroupⅤ: collagen injected + Hydroponic cultured Ginseng leaf Extract 50mg/kg treated Rat, GroupⅥ: collagen injected + leflunomide 3.5mg/kg treated Rat. We analyzed hemotological variation and kidney function test by complete blood cell counter and biochemical examination. Also we experimented western blotting for investigate signal transduction protein expression differences in four groups. These findings suggested that oral administration of hydrophonic cultured Ginseng leaf extract can attenuated inflammatory and have a kideny function improvement effect. 본 연구는 류마티스 관절염 동물 모델의 신장 기능 저하에 따른 수경인삼 잎 추출액의 효과 알아보고자 하였다. 류마티스 관절염 동물 모델은 타입 Ⅱ collagen + adjuvant를 7일동안 연속적으로 쥐의 꼬리에 주입하였다. 실험군은 그룹Ⅰ: Control 그룹(n=5), 그룹Ⅱ: collagen 주입군, 그룹Ⅲ: collagen 주입 + 수경인삼 잎 추출액 200mg/kg 투여군, 그룹Ⅳ: collagen 주입 + 수경인삼 잎 추출액 100mg/kg 투여군, 그룹Ⅴ: collagen 주입 + 수경인삼 잎 추출액 50mg/kg 투여군, 그룹Ⅵ: collagen 주입 + leflunomide 3.5mg/kg 투여군으로 나누었다. 우리는 혈액검사와 생화학검사를 통한 혈액학적 변화를 통해 신장기능 효과에 대한 실험을 하였고, 단백질정량분석을 통한 그룹간의 신호전달 단백질 발현의 차이를 조사하였다. 실험결과는 수경인삼 잎 추출액의 경구투여가 신장기능 유지 및 전신성 염증 조절을 할 수 있을 것으로 시사된다.

이준선,이길현,현경예 사단법인 인문사회과학기술융합학회 2015 예술인문사회융합멀티미디어논문지 Vol.5 No.4

Anxiety is a most common psychological disease, caused by stress. Many drugs for treated anxiety have various side effects and natural resources have a possibility as alternate material to eradicate these side effects. In this study is investigate inflammation modulate effects of Glycyrrhiza uralensis (GU) Extract in Forced Swimming Test (FST) induced depression rat model. 1 day after FST implemented during 15 min to training for rats, we measured FST and Y-maze test during each 6min, 3min to lock for acute effects of GU Extract, likewise measured behavior response with same method for chronic effects of GU Extract. We orally administerd EU extract 100mg/kg and Sodium Tianeptine 10mg/kg. Researcher result showed oral administration of GUF Extracts significantly redused immobility time and increased total entries, total distance, down regulation of iNOS, Nrf2 expression in medulla oblongata and adrenal gland, anti-anxiety modulatory effect. 불안증은 스트레스에 의해 나타나는 가장 일반적인 정신 질환이다. 불안증을 치료하기 위한 여러 약제들은 다양한 부작용을 가지고 있으며 천연물질은 이러한 부작용을 극복할 대체물질로서 사용이 가능하다. 본 연구는 강제수영실험으로 유도된 불안증 동물 모델에서의 감초 추출물의 염증조절에 따른 신경보호효과를 조사하였다. 랫을 하루 전에 강제수영실험을 15분동안 실시하여 적응시키고, 감초추출물의 경구투여하고 30분 뒤에 급성스트레스효과를 보기 위해 6분동안 강제수영실험, 3분동안 Y자 미로실험을 실시하였다. 5일간의 연속적으로 감초추출물을 경구투여하고 마찬가지로 만성효과를 보기 위해 동일한 방법으로 행동반응을 측정하였다. 감초 추출물을 100mg/kg, 양성 대조군으로 티아넵틴나트륨을 10mg/kg 투여하였다. 실험 결과는 감초추출물의 경구투여가 부동시간을 유의하게 감소시켰고, Y자 미로에서 총 입장횟수와 이동거리가 증가하였으며, 연수와 부신에서 iNOS와 Nrf2의 단백질 발현을 조절하였으며, 항우울 효과를 보여 준 것으로 사료 된다.
