Jing-shu Xu,Yong-xin Li,Xiao-li Yang 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.10

Soil strength nonlinearity and dilatancy have significant impacts on the stability of a slope. In the present analysis, a seismic stability analysis of a three-dimensional two-stage slope considering the joined influences of soil strength nonlinearity and dilatancy is conducted. Based on the limit analysis method, the external work rates by soil weight and the seismic forces as well as the internal energy dissipations are calculated and thereafter the critical height of the slope is derived. In virtue of the nonlinear optimization procedure, the stability factor of a 3D slope subjected to seismic forces is captured. The effects of slope geometry, seismic forces, soil strength nonlinearity and dilatancy on the slope stability are investigated by parameter analysis. It is found from the results that, the depth coefficient α1 and dilative parameter n have positive effects on the stability of a two-stage slope while the other factors such as the seismic coefficient kh and the nonlinear coefficient m have negative effects on it. In addition, the effect of soil nonlinearity on slope stability aggravates when the seismic force coefficient kh and the dilative parameter n increase.

Effects of seismic force and pore water pressure on three dimensional slope stability in nonhomogeneous and anisotropic soil

Jing-shu Xu,Xiao-li Yang 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.5

Soils are generally nonhomogeneous and anisotropic in fact even through it was considered homogeneous in most geotechnicalengineering analysis. In this paper, based on the kinematical approach of limit analysis theorem, a stability analysis of threedimensional nonhomogeneous and anisotropic slope subjected to seismic force or the pore water pressure was conducted, with theanalytical expression of the critical height derived, the stability factors under different nonhomogeneous and anisotropic coefficientsas well as the seismic force or the pore water pressure conditions were optimized and illustrated. The results showed that 3D effect ofslope is closely related with the ratio of slope width to slope height, increase of soil nonhomogeneous coefficient and decrease of soilanisotropic coefficient will enhance slope stability, the seismic force and the pore water pressure will not only influence the slopestability significantly but also change the rules of factors such as the slope angle as well as soil nonhomogeneity and anisotropy onslope stability.

Han, Shu-Jing,Guo, Qing-Qing,Wang, Ting,Wang, You-Xin,Zhang, Yu-Xiang,Liu, Fen,Luo, Yan-Xia,Zhang, Jie,Wang, You-Li,Yan, Yu-Xiang,Peng, Xiao-Xia,Ling, Rui,He, Yan Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

Objective: Both estrogen receptors, ER alpha ($ER{\alpha}$) and ER beta ($ER{\beta}$), are expressed in 50-70% of breast cancer cases. The role of $ER{\alpha}$ as a prognostic marker in breast cancer has been well established as its expression is negative correlated with tumor size and lymph node metastasis. $ER{\beta}$ is also a favorable prognostic predictor although this is less well documented than for $ER{\alpha}$. Materials and Methods: To explore whether ERs independently or together might influence clinical outcome in breast cancer, the correlation between the ERs with the clinicopathological features was analyzed in 84 patients. Results: $ER{\alpha}$ expression negatively correlated with tumor stage (r=-0.246, p=0.028) and tended to be negatively correlated with lymph node status (r=-0.156, p=0.168) and tumor size (r=-0.246, p=0.099). Also, $ER{\beta}$ was negatively correlated with nodal status (r=-0.243, p=0.028), as was coexpression of $ER{\alpha}$ and $ER{\beta}$ (p=0.043, OR=0.194, 95% CI= 0.040-0.953). Conclusion: Coexpression of ERs might serve as an indicator of good prognosis in breast cancer patients.

Experiment was proceed with two type of washers to compare energy consumption, washing performance, rinsing effectiveness further, damage caused by entanglement of laundry and fabric was assessed. Detergent P and T were used to compare the performance related to differences of ingredients of detergent. Soiled fabrics of EMPA 108 set were used to evaluate performance of washing by different types of contamination. A summary of experimental results are : First, for the consumption of water, drum-type washer consumed 53% less than pulsator-type washer. On the other hand, the washing time was almost similar for both these machines, but pulsator-type washer showed shorter progress, implying that power saving was more efficient in this case. Second, the drum-type washer showed better performance for contamination with all types of detergent, but the pulsator-type washer showed better rinsing performance. Third, the drum-type washer performed less data of tangle level and fabric damage. Fourth, detergent “P” exhibited better washing performance than did detergent “T”, regardless of the type of soil. And with no limit of detergent variety, water-soluble protein soil showed high removal rate, liposoluble soil especially pigment was hardly removed.

중국 사회주의 프로파간다 영화 ‘양판희(樣板戱)’의 사상과 관객성

왕주청 ( Wang Shu Jing ) 부산대학교 영화연구소 2016 아시아영화연구 Vol.8 No.2

‘양판희(樣板戱)’는 문학에 대한 정치적 영향력이 극대화되었던 1966년~1976년까지의 문화대혁명 시기에 유행 되었던 문예 형식이다. ‘양판희’의 ‘양판(樣板)’이라는 용어는 모범이라는 의미로 통한다. 특히 ‘혁명 양판희(革命樣板戱)’1)란 용어는 특정 형식을 지니고 있는 8개의 혁명 모범극을 가리키는데, 다양한 극의 형태를 가지고 있는 ‘혁명 양판희’에 해당되는 예술장르로는 ‘경극 현대희’2) 다섯 작품과 발레극 두 작품, 그리고 교향악 작품등이 해당된다. ‘양판희’는 문화대혁명 시기 전부터 싹트기 시작했으며, 문화대혁명 10년 동안 대중의 오락생활을 강하게 지배하게 되면서 성행하다가 10여년의 침체기를 가진 후 80년대 말부터 다시 관객 앞에 서기 시작하였다. 이번 연구를 통해서 오랜 시간동안 변화의 과정을 겪으면서 살아남은 중국의 문예형식 ‘양판희’ 속에 잠재되어 내려오고 있는 ‘양판희’만의 강인한 생명력과 예술성을 발견할 수 있을 것이다. The general development, from the theatre of ‘Model Operas’ to ‘Model Operas Films’ is an combination from the hard work of countless artists. There is no doubt that the rising tide of ‘Model Operas’, had been created the most significant witness of irreplaceable culture event in China. Throughout the art history in or outside of China, It was unprecedented thing for its extension, continuity and influence as well. Since the end of Culture Revolution, ‘Model Operas’ has been sparked again and set in a new communication upsurge by the means of theatre, film and the other forms of mass media, and caused a lot of controversy. Most of the study about ‘Model Operas’ has been concentrated on its ‘pitfall art’ essence, especially its negative influence on political. However, with the development of the feature, essence and function of ‘Model Operas’, there has raised quite a few phenomena that hadn``t been noticed from the dimension of film Aesthetics.

중국 펀드투자자의 투자교육경험 및 의향에 따른 펀드투자행동

이주정(Li Shu Jing),김민정(Min Jeung Kim) 한국FP학회 2016 Financial Planning Review Vol.9 No.1

본 연구에서는 중국의 펀드투자 경험이 있는 금융소비자를 대상으로 펀드투자 관련 교육의 경험과 의향에 따라 ‘투자교육 경험집단’, ‘투자교육 잠재집단’, ‘투자교육 무관심 집단’으로 분류하여 펀드투자행동에 어떠한 차이가 있는지를 살펴보았다. 이로써 투자교육과 의향이 펀드투자자의 행동에 어떻게 반영되고 있는지를 파악하고 향후 중국금융소비자들의 투자교육에 대한 기초자료를 제공할 수 있을 것으로 생각된다. 본 연구의 결과를 바탕으로 중국의 펀드투자시장에 대한 제언을 하면 다음과 같다. 첫째, 중국의 펀드투자자는 정보획득과정에서 스스로 정보를 탐색하기보다는 주변 사람을 의존하여 소극적으로 탐색하는 편이다. 따라서 투자자들에게 정확한 정보를 제공하기 위해 접근성이 좋은 채널 확보와 만화나 스마트폰 앱 등과 같이 보다 쉬운 방식으로 관련 내용을 전달할 수 있도록 노력하여야 한다. 둘째, 모든 집단에서 투자자정보 확인서 작성, 투자자성향진단, 투자설명확인서 확인 등에 대해 솔직하게 작성하지 않는 투자자 존재하였으나, 투자교육을 받은 집단이 다른 집단에 비해 그 비중이 상대적으로 더 적었다. 이는 금융회사나 중국소비자협회에서 투자자들에게 투자관련 교육을 제공하여 금융소비자의 책임감을 이끌 수 있음을 의미한다. 셋째, 금융소비자로서 이행해야 하는 행동을 올바르게 수행한 비중은 투자교육 경험집단, 투자교육 잠재집단, 투자교육 무관심집단의 순으로 나타났다. 따라서 향후 투자교육 대상자를 선정할 경우 그 효과가 높을 것으로 예상된다. This study targets China’s fund investors, with the aim of studying investment behavior with regard to the fund-purchasing process. In particular, the study focuses on the investment behavior and its dependence on the experience and intentions of fund invest education. The findings suggest the necessity of fund education, and fund education should be treated as a basic material. The results of this study are summarized as follows: First, based on the fund investment behavior results, the “source of information on the fund” before purchase for the “education group” was mainly from the financial institutions’ specific instructions, as well as the company’s website, whereas the “potential educational group” mainly used Internet information. When registering a fund, the first consideration of the “unconcerned with education group” was the company’s reputation regarding operational fund assets, with 32.4 percent indicating this, which is higher than for the other two groups. Before purchasing a fund, 32% of investors compared four or more different funds for the “education group” and the “potential educational group,” as opposed to only 13.2% for the “unconcerned with education group”. Second, with regard to investors who buy funds through financial institutions, the investment behavior when purchasing a fund and the reasons for the financial institutions selected can be divided into three categories: for the “education group,” the major reason is to select the type of commodity; for the “unconcerned with education group,” the major reason is proximity to home or company; and the “potential education group” pays attention to the qualifications of the sales staff qualifications. A higher proportion of the education group checks the qualifications of sales staffs, avoids fund companies that have received negative news recently, confirms investment instructions carefully, and asks for further explanation if they do not understand. Based on these results, fund education plays a key role in determining fund purchasing, and has an important and positive impact on investment behavior. In addition, fund education for those purchasing funds through networks also plays a key role. Third, in examining the results on whether or not investors check the management report, the “education group” and the “unconcerned with education group” have a higher relative proportion. The “education group” members are educated so they read the management report, which further demonstrates the need for education. For the “unconcerned with education group,” although they have a high proportion who read the management report, their lack of intention to seek further education reflects their over confidence in understanding fund products. In reviewing the results on the frequency of investment achievement and assets constitute content confirming, the “education group” and the “potential education group” do not often confirm investment results, which is consistent with Park (2015), who examined investment in education of those showing over confidence. The “unconcerned with education group,” in comparison with the other groups, confirm the outcome of investments relative to the high frequency. Several recommendations are presented based on these conclusions.: First, in order to provide accurate information to fund investors, financial institutions need to establish easily accessible channels, such as comic books and mobile phone software. Second, in investor information confirmations, tendency determinations, instructions confirmations, and other processes, there are no real circumstances of individual consummation. The correct use of specific educational content will correct investment behavior. Third, among the fund investors, few correctly performed the action, with the proportions increasing in the order of the “education group,” “potential education group,” and the “unconcerned with education group.” The “potential education group” can be better p

Tong Ren,Jing Suo,Shikai Liu,Shu Wang,Shan Shu,Yang Xiang,Jing-He Lang 대한부인종양학회 2018 Journal of Gynecologic Oncology Vol.29 No.5

Objectives: We analyzed the chromosomal-arm-level copy number alterations (CNAs) in the cervical exfoliative cell and tissue samples by using the low-coverage whole genomic sequencing technique. Methods: In this study, we retrospectively collected 55 archived exfoliated cervical cell suspension samples and the corresponding formalin-fixed and paraffin-embedded tissue section samples including 27 invasive cervical cancer and 28 control cases. We also collected 19 samples of the cervical exfoliative cells randomly from women to verify the new algorithm model. We analyzed the CNAs in cervical exfoliated cell and tissue samples by using the low-coverage next generation of sequencing. Results: In the model-building study, multiple chromosomal-arm-level CNAs were detected in both cervical exfoliated cell and tissue samples of all cervical cancer cases. By analyzing the consistency of CNAs between exfoliated cells and cervical tissue samples, as well as the heterogeneity in individual patient, we also established a C-score algorithm model according to the chromosomal-arm-level changes of 1q, 2q, 3p, 7q. The C-score model was then validated by the pathological diagnosis of all 74 exfoliated cell samples (including 55 cases in model-building group and 19 cases in verification group). In our result, a cutoff value of C-score >6 showed 100% sensitivity and 100% specificity in the diagnosis of cervical cancer. Conclusion: In this study, we found that CNAs of cervical exfoliated cell samples could robustly distinguish invasive cervical cancer from cancer-free tissues. And we have also developed a C-score algorithm model to process the sequencing data in a more standardized and automated way.

Formation Tracking Control for Multi-agent Systems: A Wave-equation based Approach

Shu-Xia Tang,Jie Qi,Jing Zhang 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.6

This paper considers the formation tracking control problem of large-scaled Multi-Agent Systems (MAS)for which the model is based on a system of mutually independent wave Partial Differential Equations (PDEs). Thespatial derivatives in the equation correspond to the underlying communication topology of the agents. A leaderfollowermode is employed in the control algorithm, with which the agents on the boundary of PDEs are chosenas leaders knowing the tracking trajectory and all the other agents are followers. Each follower has only the informationof its own relative position and velocity to its topological neighbors. With a designed distributed controller,the formation tracking error is bounded by a constant proportional to the acceleration of the desired trajectory. Robustness of the control law to a perturbation in the velocity measurement is also discussed. Furthermore, somesimulation studies are provided to show the effectiveness of the control algorithm.
