Many researches have been performed comparing object-based classification (OBC) and pixel-based classification (PBC), particularly in classifying high-resolution satellite images. VNREDSat-1 is the first optical remote sensing satellite of Vietnam with resolution of 2.5 m (Panchromatic) and 10 m (Multispectral). The objective of this research is to compare two classification approaches using VNREDSat-1 image for mapping mangrove forest in Vien An Dong commune, ngoc Hien district, Ca Mau province. ISODATA algorithm (in PBC method) and membership function classifier (in OBC method) were chosen to classify the same image. The results show that the overall accuracies of OBC and PBC are 73% and 62.16% respectively, and OBC solved the “salt and pepper” which is the main issue of PBC as well. Therefore, OBC is supposed to be the better approach to classify VNREDSat-1 for mapping mangrove forest in ngoc Hien commune.

Molybdate doped-polypyrrole (PPy) was electropolymerised on the mild steel surface. The morphology of polymer film was studied with scanning electron microscopy (SEM). The chemical structure of polymer was characterized with Raman spectroscopy. The presence of molybdate doped inside polypyrrole was identified by EDX spectra. The thermal analysis (TGA) showed that polypyrrole was stable up to 500 °C. The corrosion protection of the polymer film was investigated by electrochemical methods showing that the polymer film acted as a barrier layer and molybdate as an inhibitor for corrosion protection of metal. Molybdate dopant was the key component of "self-healling" polypyrrole film.

Pelvic organ prolapsed is a common problem today, and it has been gradually increasing because of the longevity of women. Pelvic organ prolapse can result in negative psychological feelings that affect on women’s sexual activity. Methods: There is a cross-sectional study on sexual dysfunction in 296 women with pelvic organ prolapse grade II and III followed up at gynecological-pelvic floor unit of hung vuong hospital from 09/2017 to 06/2018. Results: The prevalence of female sexual dysfunction in PISQ-12 was 76.4% and 95% CI [71.6 - 81.2]. The rate of female sexual dysfunction in turn is: 1) Behavioral-Emotional: 93.6% 95% CI [90.8 - 96.4]. 2) Physiology: 62.2% CI 95% [56.7 - 67.7]. 3) Relationship to partner: 89.5% 95% CI [86.0 - 93.0]. Factor related to sexual dysfunction in women with pelvic organs (p < 0.05) is general sexual dysfunction: 1) Age group: women over age 55 increased generally the risk of sexual dysfunction, OR = 5.89, 95% CI [1.38 - 25.20]. 2) Diabetes mellitus increased the risk of sexual dysfunction with OR = 5.03, 95% CI [1.42 - 17.82]. 3) Patients with previous abortions reduced the risk of sexual dysfunction with OR = 0.49 95% CI [0.27 - 0.90]. Conclusion: Research on quality of life in pelvic organ prolapse should be considered more in the future.

Asphalt pavement rtting is a major safety concem and is one of the main distress modes of asphalt *** into asphalt pavement mixes that provide strong resistance for nutting is considered of great significance as it can help provide extended pavement life and significant cost savings in pavement maintenance and *** objectives of this study are to develop numernical models to investigate the ntting of asphalt concrete pavements and to find optimal design of asphalt pave-ment mix for nutting ***-dimensional Finite Element mod-els were first developed to simulate both the axial compression and wheel track testing in which a visco elastic-plastic material model was used to predict the ntting of the asphalt concrete pavements.A strain hardening creep model with the material parameters developed from experimental testing was employed to model the time-dependent characteristics of the asphalt concrete *** results were validated against the pre-vious experimental wheel track test results of different pavement ***,optimisation techniques using the Design Of Experiments method were applied to the simulation rutting results by varying creep parameters to identify their effects on rutting resistance in order to obtain an optimal asphalt pavements *** results of this paper clearly demonstrate an efficient and effective experimental-numerical method and tool set towards optimal design for asphalt concrete pavements for rutting resis-tance.

我们是来自越南及意大利的青年建筑师团队,在越南开设了一家建筑工作室。2016年10月,我们在河内租赁了一个办公空间。在了解河内市周边环境后,我们发现,可能由于市区里的灰尘、噪音和防盗等问题,这里有很多阳台都未被实际使用。市民几乎不与外部环境或附近的邻居互动。我们把那些阳台称为沉寂空间。
