The Consciousness of Homeland and National Identity: The Study on Oba Minako’s Shabby Museum

Dongmei Hou 건국대학교 아시아·디아스포라 연구소 2016 International Journal of Diaspora&Cultural Critici Vol.6 No.1

Oba Minako is the representative of the female writers in the Japanese post-war literary arena, who are known as “the introverted generation”. Shabby Museum, one of her medium-length novels, won the Japanese Female Literary Award in 1975. This novel gives an account of the life of three Asian females living in Alaska. The author, taking Alaska, a city of wasteland, as the stage, keeps on focusing on the “postwar” life and spiritual state of the females and successfully portrays the image of “spirit of rebellion” of the heroines who are suffer war damage. As an important part of female writing, Shabby Museum is one of Oba’s major pieces, in which she has not only carried out a profound analysis of the cruelty of war and the existence of females, but also explored the ideal of harmonious co-existence of human beings. The novel also highlights the heroines’ loss of national identity and “the consciousness of homeland”. During the process of exploring the possibility of coexistence of multi-racial groups and the diversity of living patterns under the multi-cultural circumstance, the novel, meanwhile, calls in question the order of the “post-war” world.

Face Recognition Using Plurality Voting and Collaborative Representation based on the Bit-plane Information

Dongmei Wei,Weidong Zhou 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.4

As a new representation technique, collaboration representation is used to represent the test sample with all training samples from all classes. Plurality voting is one of the most widely used combination strategies in pattern recognition. This paper presents a new and an efficient face recognition approach using plurality voting and collaboration representation based on the binary bit-plane images. First, face gray images are equalized and decomposed. Next,employing collaboration representation and the corresponding five bit-plane images which have more discrimination information,five identities about the same test image can be obtained. Finally, these five identities vote to the true identity of the test image. If the plurality voting fails, the true identity of the test image will be decided by virtual weight sum face images constructed by 8 bit-plane images with collaboration representation. Weight vector, which is important for the virtual images, is determined by the recognition rate and the order of bit planes. The extensive experiments demonstrate the proposed approach has the higher right recognition accuracy and its speed is faster than the SRC prominently.

DYNAMICS CHARACTERISTICS ANALYSIS AND CONTROL OF FWID EV

Dongmei Wu,Haitao Ding,Changqing Du 한국자동차공학회 2018 International journal of automotive technology Vol.19 No.1

Compared with internal combustion engine (ICE) vehicles, four-wheel-independently-drive electric vehicles (FWID EV) have significant advantages, such as more controlled degree of freedom (DOF), higher energy efficiency and faster torque response of an electric motor. The influence of these advantages and other characteristics on vehicle dynamics control need to be evaluated in detail. This paper firstly analyzed the dynamics characteristics of FWID EV, including the feasible region of vehicle global force, the improvement of powertrain energy efficiency and the time-delays of electric motor torque in the direct yaw moment feedback control system. In this way, the influence of electric motor output power limit, road friction coefficient and the wheel torque response on the stability control, as well as the impact of motor idle loss on the torque distribution method were illustrated clearly. Then a vehicle dynamics control method based on the vehicle stability state was proposed. In normal driving condition, the powertrain energy efficiency can be improved by torque distribution between front and rear wheels. In extreme driving condition, the electric motors combined with the electro-hydraulic braking system were employed as actuators for direct yaw moment control. Simulation results show that dynamics control which take full advantages of the more controlled freedom and the motor torque response characteristics improve the vehicle stability better than the control based on the hydraulic braking system of conventional vehicle. Furthermore, some road tests in a real vehicle were conducted to evaluate the performance of proposed control method.

Experimental investigation of vortex-induced aeroelastic effects on a square cylinder in uniform flow

Dongmei Huang,Teng Wu,Shiqing He 한국풍공학회 2020 Wind and Structures, An International Journal (WAS Vol.30 No.1

To investigate the motion-induced aeroelastic effects (or aerodynamic feedback effects) on a square cylinder in uniform flow, a series of wind tunnel tests involving the pressure measurement of a rigid model (RM) and simultaneous measurement of the pressure and vibration of an aeroelastic model (AM) have been systematically carried out. More specifically, the aerodynamic feedback effects on the structural responses, on the mean and root-mean-square wind pressures, on the power spectra and coherence functions of wind pressures at selected locations, and on the aerodynamic forces were investigated. The results indicated the vibration in the lock-in range made the shedding vortex more coherent and better organized, and hence presented unfavorable wind-induced effects on the structure. Whereas the vibration in the non-lock-in range generally showed insignificant effects on the flow structures surrounding the square cylinder.

Genetic homogeneity between populations of cotton bollworm from Xinjiang, China

Dongmei Wang,Xianming Yang,Haiqiang Li,Akedan Wuwaishi,Ruifeng Ding,Haobin Li,Hongsheng Pan,Jian Liu,Yao Xu,Yan-Hui Lu 한국응용곤충학회 2018 Journal of Asia-Pacific Entomology Vol.21 No.1

We studied the population structure of cotton bollworm (CBW), Helicoverpa armigera (Hübner) (Lepidoptera:Noctuidae), in Xinjiang, the largest cotton-growing region in China, using a fragment of cytochrome c oxidasesubunit I (COI) gene. Alignments of all 192 COI sequences revealed 28 haplotypes including 23 in southernXinjiang, 5 in eastern Xinjiang and 13 in northern Xinjiang. Negative and significant values of neutrality tests forthe Tajima's D and Fu's FS parameters, combined with the high values of haplotype diversity (Hd), low values ofnucleotide diversity (π) and a high number of low frequency haplotypes indicated a recent demographic expansionof Xinjiang CBW populations. Analysis of molecular variation (AMOVA) indicated low and non-significantgenetic structure, regardless of geographical scale or crop, with most of genetic variation occurringwithin local CBW populations. Pairwise FST analyses also indicated low genetic differentiation. This demographicevent and high gene flow could be responsible for the low genetic structure currently found. CBW populations inXinjiang need to be considered as one panmictic unit in its management, especially for the design of refuges todelay the development of resistance by this migratory pest to transgenic Bt (Bacillus thuringiensis) cotton.

Wnt/β-catenin interacts with the FGF pathway to promote proliferation and regenerative cell proliferation in the zebrafish lateral line neuromast

Dongmei Tang,Yingzi He,Wenyan Li,Huawei Li 생화학분자생물학회 2019 Experimental and molecular medicine Vol.51 No.-

Wnt and FGF are highly conserved signaling pathways found in various organs and have been identified as important regulators of auditory organ development. In this study, we used the zebrafish lateral line system to study the cooperative roles of the Wnt and FGF pathways in regulating progenitor cell proliferation and regenerative cell proliferation. We found that activation of Wnt signaling induced cell proliferation and increased the number of hair cells in both developing and regenerating neuromasts. We further demonstrated that FGF signaling was critically involved in Wnt-regulated proliferation, and inhibition of FGF abolished the Wnt stimulation-mediated effects on cell proliferation, while activating FGF signaling with basic fibroblast growth factor (bFGF) led to a partial rescue of the proliferative failure and hair cell defects in the absence of Wnt activity. Whole-mount in situ hybridization analysis showed that the expression of several FGF pathway genes, including pea3 and fgfr1, was increased in neuromasts after treatment with the Wnt pathway inducer BIO. Interestingly, when SU5402 was used to inhibit FGF signaling, neuromast cells expressed much lower levels of the FGF receptor gene, fgfr1, but produced increased levels of Wnt target genes, including ctnnb1, ctnnb2, and tcf7l2, while bFGF treatment produced no alterations in the expression of those genes, suggesting that fgfr1 might restrict Wnt signaling in neuromasts during proliferation. In summary, our analysis demonstrates that both the Wnt and FGF pathways are tightly integrated to modulate the proliferation of progenitor cells during early neuromast development and regenerative cell proliferation after neomycin-induced injury in the zebrafish neuromast.

Portal pressure gradient and serum albumin: A simple combined parameter associated with the appearance of ascites in decompensated cirrhosis treated with transjugular intrahepatic portosystemic shunt

Dongmei Zhao,Guobing Zhang,Mingquan Wang,Chaoxue Zhang,Jiabin Li 대한간학회 2019 Clinical and Molecular Hepatology(대한간학회지) Vol.25 No.2

Background/Aims: In recent years, greater assessment accuracy after transjugular intrahepatic portosystemic shunt (TIPS) to ascertain prognosis has become important in decompensated cirrhosis due to portal hypertension. The aim of this study was to assess the ratio of the portal pressure gradient (PPG) pre-TIPS (pre-PPG) to albumin (PPA), which influence ascites formation in cirrhotic patients in the 6-months after TIPS placement, and is a metric introduced in our study. Methods: This was a retrospective cohort study of 58 patients with decompensated cirrhosis admitted to an academic hospital for the purpose of TIPS placement. We collected the following data: demographics, laboratory measures, and PPG during the TIPS procedure. Then we analyzed the association between the above data and ascites formation post- TIPS in cirrhosis patients. Results: Twenty-two patients with ascites and 28 without ascites were evaluated. Univariate and binary logistic regression analysis were adjusted for the following variables: to determine prognosis; Child-Pugh scores, lymphocyte count, platelet count, hemoglobin level, albumin level and pre-PPG or PPA. The outcome showed that PPA was better than pre-PPG and albumin for predicting ascites according to area under receiver operating characteristic curves and a statistical model that also showed PPA’s influence 6-months post-TIPS. Conclusions: The combined measurement of pre-PPG and albumin, defined as PPA, may provide a better way to predict post-TIPS ascites in decompensated cirrhosis, which underlines the need for a large clinical trial in the future.
