요서 지역 거란 전탑에 관하여

백만달 ( Bai Man Da ) 국제뇌교육종합대학원 국학연구원 2019 선도문화 Vol.27 No.-

거란은 중국 북방을 통치한 이백 여 년 동안 전탑을 대량적으로 건축하여 연대가 확실한 거란 전탑은 통계로 인해 백 여 개 보존하고 있으나 연대가 확실하지 않아 애매모호한 전탑을 포함하면 거란은 전탑을 300 여개 건축하였다. 이러한 많은 전탑을 건축할 때 인력, 물력, 재력을 얼마나 필요 했었는지. 또는, 왜 이러한 많은 전탑을 건축하였는지. 이것은 거란은 전탑을 불교 용도로만 사용한 뿐만 아니라 거란의 사회에서도 중요한 역할을 한 것이다. 현재 학계에서 거란 전탑을 연구할 때는 그의 불교적과 건축학적 방면에서만 연구하고 있으니 본문은 다른 관점에서 거란 전탑을 연구하고자 하였다. 본문은 거란 전탑의 도로 표지물에 적응, 바람과 전탑에 관계, 하늘과 전탑에 관계 등 여러 영역에서 거란 전탑을 고찰하였다. Qidan For more than two hundred years of rule over the northern part of China, the brick pagodas, which is believed to have been built in large quantities, has preserved more than a hundred of its pagodas due to statistics, but because of its lack of solidarity, it has built over 300 brick pagodas. How much manpower, material and resources were needed to build these many brick pagodas. Or, why Qidan built so many of these brick pagodas. This is an important part of the brick pagodas society as well as the use of the brick pagodas for Buddhist purposes. In the present academic world, when studying the brick pagodas, them only studies it in his Buddhist and architectural fields, so the text was to study the brick pagodas from a different perspective. The text examined the giant brick pagodas in various areas, including its adaptation to the road signs of the giant brick pagodas, its relation to the wind and the brick pagodas, and its relation to the sky and the brick pagodas.

Carya cathayensis is an important economic nut tree that is endemic to eastern China. As such, outbreaks of root rot disease in C. cathayensis result in reduced yields and serious economic losses. Moreover, while soil bacterial communities play a crucial role in plant health and are associated with plant disease outbreaks, their diversity and composition in C. cathayensis are not clearly understood. In this study, Proteobacteria, Acidobacteria, and Actinobacteria were found to be the most dominant bacterial communities (accounting for approximately 80.32% of the total) in the root tissue, rhizosphere soil, and bulk soil of healthy C. cathayensis specimens. Further analysis revealed the abundance of genera belonging to Proteobacteria, namely, Acidibacter, Bradyrhizobium, Paraburkholderia, Sphaerotilus, and Steroidobacter, was higher in the root tissues of healthy C. cathayensis specimens than in those of diseased and dead trees. In addition, the abundance of four genera belonging to Actinobacteria, namely, Actinoallomurus, Actinomadura, Actinocrinis, and Gaiella, was significantly higher in the root tissues of healthy C. cathayensis specimens than in those of diseased and dead trees. Altogether, these results suggest that disruption in the balance of these bacterial communities may be associated with the development of root rot in C. cathayensis, and further, our study provides theoretical guidance for the isolation and control of pathogens and diseases related to this important tree species.

Wing weight estimation considering constraints of structural strength and stiffness in aircraft conceptual design

Bai, Chen,Mingqiang, Luo,Zhong, Shen,Zhe, Wu,Yiming, Man,Lei, Fang The Korean Society for Aeronautical and Space Scie 2014 International Journal of Aeronautical and Space Sc Vol.15 No.4

According to the requirement of wing weight estimation and frequent adjustments during aircraft conceptual design, a wing weight estimation method considering the constraints of structural strength and stiffness is proposed to help designers make wing weight estimations rapidly and accurately. This method implements weight predictions on the basis of structure weight optimization with stiffness constraints and strength constraints, which include achievement of wing shape parametric modeling, rapid structure layout, finite element (FE) model automated generation, load calculation, structure analysis, weight optimization, and weight computed based on modeling. A software tool is developed with this wing weight estimation method. This software can realize the whole process of wing weight estimation with the method and the workload of wing weight estimation is reduced because much of the work can be completed by the software. Finally, an example is given to illustrate that this weight estimation method is effective.

The purpose of this study was to investigate the variance of the center of gravity resulting from physical developement. The subjects of the study were 1,120 boys who ranged in age 6 to 19 yr,and 1,020 girls ranged in age 6 to 18 yr in Jeju Do. They were selected random sampling procedure, and measured on the center of gravity and physique. Data were statistically analyzed, and within the limitations of the present study the following conclusions were drawn: 1. Physical growth was gradually increased both in male and female, but the center of gravity for the subjects gradually decreased, width decreased was 3.81% ranged from 59.51% to 55.70% in male (6 to 19 yr), and 4.42% ranged from 59.17% to 54.75% in female(6 to 18 yr). 2. The product-moment correlations between the center of gravity and height were statistic- ally significant (p<.01)and ranged from r=-.641 (in male)to r=-.774(in female). 3. The product-moment correlations between the center of gravity and body weight were stat- istically significant(p<.01)and ranged from r=-.524(in male)to r=-.763(in fmale). 4.The product-moment correlations between the center of gravity and sitting height were staistically significanr(p<.01)and ranged from r=-.594(in male)to r=-.434(in female). 5. The product-moment correlations between the center of gravity and girth of chest were statistically significant(p<.01)and ranged from r=-.446(in male)to r=-.796(in female) 6.

Due to high-speed of trains the track deformation increases rapidly and may lead to track irregularities causing the track stability problem. To secure the track stability the continual inspection on track irregularities is required. The paper presents a methodology for identifying track irregularity using the NARX neural network considering non-linearity in the train structural system. A simulation study has been carried out to examine the proposed method. Acceleration time history data measured at a bogie were re-sampled to every 0.25m track irregularity. In the simulation study two sets of measured data were simulated. The second data set was obtained by a train with 10% more mass than the one for the first data set. The first set of simulated data was used to train the series-parallel mode of NARX neural network. Then the track irregularities at the second time period are identified by using the measured acceleration data. The closeness of the identified track irregularity to the actual one is evaluated by PSD and RMSE.

The VC contents in strawberries which were sold in the market, and the change of V-C contents in strawberries during stored in the room temperature (I8-26°C) or in a refrigerator(3-5°C) were observed. The V-C contents in the fresh strawberries which were sold in the market were 26.6-76.4mg% in total V-C, and 20.6-72.6mg% in reductive form V-C. The V-C contents in the strawberries which were stored in the room temperature were decreased faster than the one stored in a refrigerator. The V-C contents in strawberries were remained less than half of the original amount after 48 hours even it stored in a refrigerator.

Early gastric cancer of signet ring cell carcinoma is more amenable to endoscopic treatment than is early gastric cancer of poorly differentiated tubular adenocarcinoma in select tumor conditions.

<P>Recently, endoscopic submucosal dissection has been carefully applied in early gastric cancer (EGC) with undifferentiated type. However, there are no individual guidelines for endoscopic treatment of EGCs with poorly differentiated tubular adenocarcinoma or signet ring cell carcinoma. The aim of this study was to investigate and compare the clinicopathologic features of these two types of EGC to guide the application of endoscopic treatment.</P>
