Background: Regular physical activity(PA) has documented effects in prevention and treatment of many non-communicable diseases(NCDs).Physical inactivity is recognized as the fourth leading risk factor for premature death, worldwide. Despite these facts, physical inactivity is increasing,not only in high-income, but also in middle-and low-income countries. To address this negative trend, evidence-based methods to increase PA are needed. The purpose of this paper is to describe the implementation and assessment of 4 strategies designed to increase PA in ***: Four strategies were used: i) introduction and evaluation of an education and training program on the Swedish method of Physical Activity on Prescription(PAP) among health care professionals, ii) translation of the PAP evidence-based handbook, Physical Activity in the Prevention and Treatment of Disease(called FYSS in Swedish) into Vietnamese, iii) launch of a mass-media campaign to promote PA, and iv)advocacy to support development of PA guidelines in ***: The evaluation indicated that the participating health care professionals had a positive attitude to PAP. However, they also reported uncertainty in prescribing PA. FYSS was translated and disseminated successfully to health care professionals. A mass-media campaign identified the beneficial effects of PA to health care professionals, journalists, policy makers, and the public. Last, the process of developing national guidelines on PA was ***: this project led to enhanced awareness and appreciation of PA in the prevention and treatment of NCDs among health care professionals as well as initiation of national PA guidelines. Important lessons also were learned in the presentation of PAP, which will be considered when designing similar projects in the future.

this study evaluated the different expressions of cherry tomato growth, yield and quality under bamboo and rice husk biochar applications to soil. The experiment was conducted under glasshouse conditions at Hakozaki campus, Kyushu University, Japan and consisted of 5 treatments, namely 1) no biochar application as a control;2) 2% (RH2) and 3) 5% (RH5) of rice husk biochar;4) 2% (BB2) and 5) 5% (BB5) of bamboo biochar. Bamboo biochar application significantly improved tomato growth, including number of leaves, fresh biomass yield of aboveground and underground parts for BB5;number of fruit;fresh yield from 24% - 25% for BB2 and BB5. In particular, both bamboo and rice husk biochar application at two rates 2% and 5% had positive effects on tomato quality, demonstrated by the increased total sugar content from 56% to 91%, and the enhancement of ascorbic acid content for BB2 and RH2 by 12% and 17%, respectively. Those improvements reflected the soil physiochemical property changes after biochar application, including the increase in plant available water for bamboo biochar amendment before and after cultivating by 25% - 38% and 9% - 18%, respectively, compared with those of control;and the increased total soil N for bamboo biochar treatments (11% - 14%). Generally, all data above support bamboo biochar utilization for the purpose of improving soil properties and developing crop production.

越南共产党第六次全国代表大会(1986年11月)提出了全面改革政策,其重点是经济改革,使国家实现工业化和现代化。随着这一政策的实施,越南经济已从官僚集中管理机制转变为具有各种经济成分和商业活动的市场经济,不仅解放了市场也增加了公民的商业自主权。经过30多年的革新,越南经济在各个领域的一体化和发展道路上迈出了一大步。为坚持经济改革,越南共产党和中央始终主张为经济改革和政策落实创造条件,吸引企业参与,而进入市场的企业必须经过注册程序。现在工商登记是企业“诞生和认可”的法律程序,因此,任何主体能满足法律条件都可以向国家主管机构注册,通过工商登记程序能够得到工商登记证书,从而使企业合法化。随着国际经济一体化进程的推进,工商登记的程序也进行了改革。越南政府已通过商业登记、税务登记,并为企业提供唯一的识别号码,商业登记也被工商登记取代。国家统一工商登记管理,从申请登记阶段开始,检查和监督业务主体的准入资格,这一举措旨在保护消费者的利益,维护整个社会和其他商业主体的共同利益。工商登记活动的全部意义就是使企业能够在市场上运作,除了商业登记证外,企业还要经营符合其他特殊法中规定的准入条件。工商登记制度根据社会发展的需要几经变迁,工商登记法营造了一个吸引所有投资资源,促进企业管理和监督的环境。国家为企业从其设立登记到生产经营创造有利条件,在退出市场时确保其正当权益。此外,工商登记是行使商业自由的一种形式,它促使商业实体参与“共同的竞争环境”。但是,从法律规定到实际执行仍存在许多矛盾和不一致,造成了企业在实施过程中的困难。企业在进入市场时需要配套更完善的法律法规,更现实、更高的实施效率以应对复杂的现实需求,这需要理论和实践方面的研究。综上,本文以越南现行工商登记的相关法律为研究对象,比较和分析工商登记法的科学论据,理论和实践规定,以期提出建设性建议。

In traumatized patients, the primary cause of mortality is uncontrollable continuous bleeding and unexpected intraoperative bleeding which is likely to increase the risk of complications and surgical failure. High expansion sponges are effective clinical practice for the treatment of wound bleeding (irregular/deep/narrow) that are caused by capillaries, veins and even arterioles as they possess a high liquid absorption ratio so can absorb blood platelets easily in comparison with traditional haemostasis treatments, which involve compression, ligation, or electrical coagulation etc. When in contact with blood, haemostatic sponges can cause platelet adhesion, aggregation, and thrombosis, preventing blood from flowing out from wounds, triggering the release of coagulation factors, causing the blood to form a stable polymerized fibre protein, forming blood clots, and achieving the goal of wound bleeding control. Haemostatic sponges are found in a variety of shapes and sizes. The aim of this review is to facilitate an overview of recent research around haemostatic sponge materials, products, and technology. this paper reviews the synthesis, properties, and characteristics of haemostatic sponges, together with the haemostasis mechanisms of haemostatic sponges (composite materials), such as chitosan, cellulose, gelatin, starch, graphene oxide, hyaluronic acid, alginate, polyethylene glycol, silk fibroin, synthetic polymers silver nanoparticles, zinc oxide nanoparticles, mesoporous silica nanoparticles, and silica nanoparticles. Also, this paper reviews commercial sponges and their properties. In addition to this, we discuss various in-vitro/in-vivo approaches for the evaluation of the effect of sponges on haemostasis .

Polyaniline (PANI) onto indium-doped tin-oxide (ITO)-coated glass samples were prepared by electroopolymerization in 0.5 M H2SO4 solution. Structure and morphology characterization of the PANI films demonstrated that the films were grown onto ITO substrates in the form of polycrystalline microbelts separated by micropores. By analysing the UV-Vis absorption spectra of the PANI films, the energy bandgap was found to be approximately 2.75 eV. The PANI/ITO films exhibited a good reversible electrochromic display (ECD) performance when cycled in 0.1 M LiClO4 + pro-pylene carbonate. The response time of the ECD coloration was found to be as small as 15 s and the coloration efficiency was found to be 8.85 cm2 C-1. After 100 cycles of the ECD performance, the cyclic voltammetry curve of the working electrode maintained unchanged. this demonstrates that the electropolymerized PANI films can be served as a good candidate for ECD applications, taking advantage of their excellent properties in terms of chemical stability.
