십전대보탕에 들어가는 한약재 10종을(국산 7종, 중국산 10종)을 수집하여 일반성분과 중성세제섬유소(neutral detergent fiber, NDF), 식이섬유(total dietary fiber, TDF; insoluble dietary fiber, IDF; soluble dietary fiber, SDF)를 분석하였다. 십전대보탕 재료 중 국내산 7종, 중국산 10종에 있어서 일반성분과 식이섬유는 국내산과 중국산간의 차이가 크지 않았다. 그러나 중성세제섬유의 경우 건조물 기준으로 국내산 $35.24\%$, 중국산 $58.64\%$로 차이가 크게 나타났다 국내산 7종의 총탄수화물(CHO)과 NDF 간에는 Y=0.32X+60.96, r=0.61(p<0.01), 총탄수화물(CHO)과 NFE간에는 Y=0.65X+32.88, r=0.76(p<0.001)로서 유의한 회귀식과 상관이 도출되었다. 그러나 총탄수화물(CHO)과 NFC간에는 Y=-0.07X+80.93, r=0.10로서 회귀식이 도출되었으나 유의성은 없었다. 중국산 10종의 총탄수화물(CHO)과 NDF간에는 Y=0.53X+49.64, r=0.69(p<0.001), 총탄수화물(CHO)과 NFE간에는 Y=0.50X+46.42, r=0.71 (p<0.01)로서 유의한 회귀식과 상관이 도출되었다. 그러나 총탄수화물(CHO)과 NFC간에는 Y=0.10X+78.21, r=0.10로서 회귀식이 도출되었으나 유의성은 없었다. 국내산 7종의 TDF와 IDF간에는 Y=0.96X+4.08, r=0.99(p<0.01), TDF와 SDF간에는 Y=-6.87X+62.97, r=0.51(p<0.01)로서 유의한 회귀식과 상관이 도출되었다. 중국산 10종의 TDF와 IDF간에는 Y=0.96X+3.14, r=0.99(p<0.01), TDF와 SDF간에 Y=-8.71X+58.96, r=0.50(p<0.01)로서 유의한 회귀식과 상관이 도출되었다. 국내산과 중국산 7종 식이섬유의 t-test 결과 TDF와 IDF는 평균이 양측검정결과 유의하게 다르지 않았으나 SDF는 평균이 유의하게 달랐지만 단측검정 결과 유의하지 않았다. This study was conducted to determine the total carbohydrate (CHO), nitrogen free extract (NFE), non fiberous carbohydrate (NFC) and ditery fiber (NDF, neutral detergent fiber; TDF, total dietary fiber; IDF, insoluble dietary fiber; SDF, soluble dietary fiber) of 17 kinds of domestic and Chinese herbs.

For sustainable development at a watershed, environment friendly site-specific management practices need to be developed and implemented. The soil and Water Assessment Tool(SWAT)model has been world-wide used to estimate stream flow, sediment, and nonpoint source pollutant loads, and effects on water quality of different management practices. In this study, the SWAT model was used to estimate the flow resources at Hwacheon areas using Digital Elevation Model(DEM),Land use, precipitation ,wind ,maximum and minimum temperature, solar radiation, humidity of watershed The R2 value and EI value for the comparison of SWAT estimated flow and measured flow were 0.87 and 0.67 respectively for calibration period, and the R2 value and E1 value for validation were 0.75 and 0.67 respectively. The comparison results show what the SWAT model is applicable to simulate hydrology behaviors at this study watershed.

Spatial structures have the different dynamic characteristics from general rahmen structures. Therefore, it is necessary to accurately analyze dynamic characteristics and seismic response for seismic design of spatial structure. Keel arch structure is used as an example structure because it has primary characteristics of spatial structures. In case of spatial structures with different ground condition and time lag, multiple support excitation may be subjected to supports of a keel arch structure. In this study, the response of the keel arch structure under multiple support excitation and with time lag are analyzed by means of the pseudo excitation method. Pseudo excitation method shows that the structural response is divided into two parts, ground displacement and structural dynamic response due to ground motion excitation. It is known that the seismic responses of spatial structure under multiple support excitation are different from those of spatial structure under simple excitation. And the seismic response of spatial structure with time lag are different from those of spatial structure without time lag. Therefore, it has to be necessary to analyze the seismic response of spatial structure under multiple support excitation and time lag because the spatial structure supports may be different and very long span. It is shown that the seismic response of spatial structure under multiple support seismic excitation are different from those of spatial structure under unique excitation.

김기철,강주원,채승훈,Kim, Gee-Cheol,Kang, Joo-Won,Chae, Seoung-Hun 한국공간구조학회 2011 한국공간구조학회지 Vol.11 No.2

현재 건축 및 토목 구조물의 진동제어에 있어서 준능동제어에 대한 연구가 많이 수행되고 있으며 준능동제어 시스템은 수동제어와 능동제어의 장점을 가지고 있다. 최근 적은 전기 에너지로 제어가 가능한 MR 감쇠기가 개발되어 준능동제어 분야에 적용되고 있으며 이러한 MR 감쇠기를 스마트 감쇠기라 불리고 있다. 본 논문에서는 실시간으로 제어가 가능한 MR 감쇠기를 인접한 두 건축물 사이에 설치하여 제어성능을 알아보고자 한다. 또한, groundhook과 skyhook 제어 알고리즘을 결합한 복합제어 모델을 인접한 건축물의 진동제어에 적용하여 복합제어 모델의 제어성능을 알아보고자 한다. 복합제어 모델을 적용하여 인접한 두 건축물의 진동제어 성능을 분석한 결과, 복합제어 모델이 인접한 두 건축물의 진동제어에 매우 효과적인 것을 알 수 있었다. Many researchers have attempted to apply semi-active control systems in the civil engineering structures. Recently, magneto-rheological(MR) fluid dampers have been developed. This MR damper is one of semi-active dampers as a new class of smart dampers. This paper discusses the application of MR damper for seismic response control of adjacent buildings subjected to earthquake. Here, a controllable damping force of MR damper that is installed between adjacent buildings is applied to seismic response control. A hybrid model combines skyhook and groundhook control algorithm so that the benefits of each can be combined together. In this paper, hybrid control model are applied to the multi degree of freedom system representative of buildings in order to reduce seismic response of adjacent buildings. And the performance of hybrid control model is compared with that of others. It was demonstrated that hybrid control model or adjacent buildings with MR damper was effective for seismic response control of two adjacent buildings reciprocally.

소아에서의 슬개골 골절은 성인을 포함한 전체 슬개골 골절의 약 2% 미만에서 발생하고, 모든 소아 골절의 약 1% 정도로 매우 드물게 발생한다. 성장중인 슬개골은 성인에서의 슬개골 골절과는 달리 골연골 골절 또는 견열 골절의 형태로 흔히 발생하며, 그 형태는 주로 소매형 골절로 나타난다. 소아 슬개골의 견열 골절 또는 소매형 골절은 슬개골의 상단부 혹은 하단부에서 발생하나, 대부분 슬개골 하단부가 주를 이루며, 상단부에 생긴 경우는 드물다. 저자들은 16세 소아에서 슬개골 상단부의 소매형 골절 1례를 경험하여 이를 문헌고찰과 함께 보고하는 바이다. Patellar fractures in children represent less than 2% of all patellar fractures including adults, and occur about 1% of all pediatric fractures. Because of property of the growing patella, osteochondral or avulsion fractures are more common in children and the most common type of patella fracture in children is sleeve fracture. Avulsion or sleeve fractures of the patella in children can occur at the superior or inferior pole of the patella. Most reported cases of sleeve fracture are involving the inferior patellar pole, but involving the superior patellar pole is very rare. We experienced a case of sleeve fracture occurred at the superior pole of the patella in a sixteen-year-old boy and report this case with literature review.

In recently, sky-bridge are often applied to high-rised adjacent buildings for pedestrian bridge. the seisnic response control of adjacent buildings have been studied and magneto-rheological(MR) fluid dampers have been applied to seismic response control. In this study, vibration control effect of the MR damper connected adjacent buildings has been investigated. Adjacent building structures with different natural frequencies were used as example structures. Two typed of control methods, displacement based or velocity based, are applied to determinate control force of MR damper. In this numerical analysis, it has been shown that displacement-based control algorithm is more effective than velocity-based control algorithm for seismic response control of adjacent buildings. And, when displacement-based control method is applied to control of adjacent buildings, the control of building occurred large displacement is more efficient in reducing the seismic response.
