The purpose of the study is to found the base experimental data by testing the adaptable time of eyes with administrating experimental conditions including source luminance, background illuminance and the position of subjects, by examining the appropriation of evaluating discomfort glare caused by actual window and simulated window. The process of the study is as follows: 1) In terms of the previous experiment, the large of Mock-up, evaluation values and subjective positions were administrated. 2) The experiment on the adaptable time of eyes is conducted with source luminance, background illuminance and the subjective position. 3) At the same Mock-up condition, the experiments for evaluating discomfort glare caused by actual window and by simulated window were conducted and contrasted. The adaptable time of eyes is rationally tested as 120 seconds with source luminance, background illuminance and the subjective position. And the difference on the boundary of evaluating values caused by actual window and simulated window ranges from 13% to 5%. On the basis of the result, the applicability of evaluating discomfort glare caused by simulated window is presented

Chinese Korean at the beginning of Qing Dynasty, besides few of who had resided in Northeast area China before China was unified by Qing Government, most of them were captured during two aggressive campaigns against Korea during the period of Qing Taizong Huang Taiji, some Korean came here initiatively during the period of Nurhachi and Huangtaiji. Unified by Qing Government, their positions were different, so function followed was utterly different. But they all were merged into the Manchu society finally. Their descendants almost don't have any continued relationship with Korean today in China.

王國維境界涚說的現代美學意义

왕국유는 중국 역사상 현대 미학을 체계적으로 연구한 첫 번째로 인물이다. 그의 境界涚은 중국의 전통적인 이론인 意境涚을 현대 미학의 범주로 이끌어 주었다. 그는 철저하게 중국 전통의 功利主义 미학관을 배격하고 이를 天功利主义 미학관으로 대체하였다. 또한 이러한 기초위에 詩學의 가치를 인생의 가치와 결합시키게 해주어 시학의 인문 가치를 높여 주었다. 무공리주의 미학관과 현대 미학 이론의 기초위에 왕국유는 독창적인 경계 미학을 창조해 내었으니, 이는 중국 미학사에서 미증유의 일이었다. 왕국유의 境界 미학은 중국 전통의 의경론과 서방 현대 미학에 대한 새로운 해석이니, 이는 중국 當代 문학 이론의 중요한 방법론이 되어 주었다. As the first person studying esthetics, WANG Guowei turned the traditional Artistic Conception into modern esthetics. He thoroughly abandoned the traditional utility esthetics and established modern no-utility esthetics. Based on no-utility esthetics, he opened poem-humanity value in china by contacting literature with humanity, created modern systematical Artistic-Conception-esthetics, based on his modern experience of human nature, he re-readed Chinese traditional Artistic Conception and modern esthetics of west.

The process of this study is as follows: 1) In terms of the previous experiment, the large of Mock-up, evaluation values and subjective positions were administrated. 2) The experiment on the recovery time of human eye is conducted by source luminance, background illuminance and the subjective position. 3) At the same Mock-up condition, the experiments for evaluating discomfort glare caused by actual window and by simulated window were conducted and contrasted. Rationally tested recovery time of human eye is 120 seconds with source luminance, background illuminance and the subjective position.

An experiment was conducted to investigate the effects of forced molting and egg storage time on the various egg qualities. A total of 240 ISA Brown layers (60 wk of age) were employed as the unmolted treatment (Control). Two hundred and forty ISA Brown layers, molted at the age of 55 wk, were used as a forced molting treatment (T1), and the same number and strain of layers, molted at the age of 70 wk. were also used as the another forced molting treatment (T2). A total of 120 eggs were sampled from each treatment, and divided into six sets, 20 eggs per set. These six sets were stored for 1, 3, 6, 9, 12, and 15 days at 18℃ temperature, respectively. Eggs from T1 were collected from laying hens at the age of 68 wk, which started molting at 60 wk of age and achieved 50% egg production at 63 wk of age. Eggs from T2 were collected from hens at 82 wk of age, which started molting at 70 wk of age and achieved 50% egg production at 78 wk of age. The eggshell strength of T1 was significantly (p<0.05) higher than the Control and T2, and the storing periods did not affect the eggshell strength at all. Neither the forced molting nor the storing periods did not exert any consistent effect on the egg weight, eggshell thickness, eggshell color and egg yolk color. The albumin heights of T1 and T2 were significantly (p<0.05) lower than the Control, and it was remarkably reduced gradually as the storage periods increased in all three treatments. The Haugh unit showed very similar trends as the albumin height, indicating that both albumin height and Haugh unit were very much related to each other. In conclusion, the forced molting improves the eggshell strength, but decreases the albumin height and Haugh unit. The storage of eggs also decreases the albumin height and Haugh unit regardless of molting.

Analysis of a mode-I crack perpendicular to an imperfect interface

Zhong, Xian-Ci,Li, Xian-Fang,Lee, Kang Yong Elsevier 2009 International journal of solids and structures Vol.46 No.6

<P><B>Abstract</B></P><P>The elastostatic problem of a mode-I crack embedded in a bimaterial with an imperfect interface is investigated. The crack is in proximity to and perpendicular to the imperfect interface, which is governed by linear spring-like relations. The Fourier transform is applied to reduce the associated mixed-boundary value problem to a singular integral equation with Cauchy kernel. By numerically solving the resulting equation, stress intensity factors near both crack tips are evaluated. Obtained results reveal that the stress intensity factors in the presence of the imperfect interface vary between that with a perfect interface and that with a completely debonding interface. Moreover, an increase in the interface parameters decreases the stress intensity factors. In particular, when crack approaches to the weakened interface closer, the stress intensity factors become larger for a sliding interface, and become larger or smaller for a Winkler interface, depending on the crack lying in a stiffer or softer material. The influences of the imperfection of the interface on the stress intensity factors for a bimaterial composed of aluminum and steel are presented graphically.</P>

Tumor Markers for Diagnosis, Monitoring of Recurrence and Prognosis in Patients with Upper Gastrointestinal Tract Cancer

Jing, Jie-Xian,Wang, Yan,Xu, Xiao-Qin,Sun, Ting,Tian, Bao-Guo,Du, Li-Li,Zhao, Xian-Wen,Han, Cun-Zhi Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.23

To evaluate the value of combined detection of serum CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS for the clinical diagnosis of upper gastrointestinal tract (GIT) cancer and to analyze the efficacy of these tumor markers (TMs) in evaluating curative effects and prognosis. A total of 573 patients with upper GIT cancer between January 2004 and December 2007 were enrolled in this study. Serum levels of CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS were examined preoperatively and every 3 months postoperatively by ELISA. The sensitivity of CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS were 26.8%, 36.2%, 42.9%, 2.84%, 25.4%, 34.6%, 34.2% and 30.9%, respectively. The combined detection of CEA+CA199+CA242+CA724 had higher sensitivity and specificity in gastric cancer (GC) and cardiac cancer, while CEA+CA199+CA242+SCC was the best combination of diagnosis for esophageal cancer (EC). Elevation of preoperative CEA, CA19-9 and CA24-2, SCC and CA72-4 was significantly associated with pathological types (p<0.05) and TNM staging (p<0.05). Correlation analysis showed that CA24-2 was significantly correlated with CA19-9 (r=0.810, p<0.001). The levels of CEA, CA19-9, CA24-2, CA72-4 and SCC decreased obviously 3 months after operations. When metastasis and recurrence occurred, the levels of TMs significantly increased. On multivariate analysis, high preoperative CA72-4, CA24-2 and SCC served as prognostic factors for cardiac carcinoma, GC and EC, respectively. combined detection of CEA+CA199+CA242+SCC proved to be the most economic and practical strategy in diagnosis of EC; CEA+CA199+CA242+CA724 proved to be a better evaluation indicator for cardiac cancer and GC. CEA and CA19-9, CA24-2, CA72-4 and SCC, examined postoperatively during follow-up, were useful to find early tumor recurrence and metastasis, and evaluate prognosis. AFP, TPA and TPS have no significant value in diagnosis of patients with upper GIT cancer.
