Sustainable Development of Enterprises: Barriers and Policy Recommendations

Enterprise development towards sustainability is a strategy that needs to set for enterprises if all existing and long-term development in the context of deeper integration and intense competition. In order to achieve the objective of sustainable development of enterprises, on the one hand, there is a need for changes of enterprises themselves, on the other hand, need to be oriented and supported by the state. In the context of open economy and fierce competition, Vietnamese enterprises have encountered barriers to the implementation of sustainable development. This study gives the concepts of sustainable enterprise development that emphasizes enterprise development activities. Then, from the identification and multidimensional analysis of these barriers, recommendations have been proposed to unravel in order to achieve the goal of sustainable enterprise development in the coming time.

Synthesis of aromatic heterocycles by Palladium(0)-catalyzed domino reactions and cyclization of hydrazone dianions

This dissertation focuses on the development of new and convenient synthetic approaches for important or new aromatic heterocycles, namely chromeno[3,4-b]pyrrol-4(3H)-ones, indolo[1,2-f]phenanthridines, azaindolo[1,2-f]phenanthridines, naphtho-fused heterocycles, and fluorinated pyrazoles, which are potential for drug discovery and advanced materials. The approaches base on palladium(0)-catalyzed domino reactions and cyclization of hydrazone dianions

The maximum power point tracking based-control system for small-scale wind turbine using fuzzy logic

This paper presents the research on small-scale wind turbine systems based on the Maximum Power Point Tracking (MPPT) algorithm. Then propose a new structure of a small-scale wind turbine system to simplify the structure of the system, making the system highly practical. This paper also presented an MPPT-Fuzzy controller design and proposed a control system using the wind speed sensor for small-scale wind turbines. Systems are simulated using Matlab/Simulink software to evaluate the feasibility of the proposed controller. As a result, the system with the MPPT-Fuzzy controller has much better quality than the traditional control system

Preparing for the Next Global Threat: A Call for Targeted, Immediate Decisive Action in Southeast Asia to Prevent the Next Pandemic in Africa

Global investments have had great impact on malaria—these are now at risk of being reversed. Cambodia is where drug resistance historically emerges and spreads globally to drive resulting pandemics—we are currently watching history repeat itself. Despite large investments and recent success in driving down overall rates of malaria, high levels of resistance to nearly all antimalarial drugs are now widespread in Cambodia. Malaria cases are again rising in both Cambodia and Vietnam. Nearly incurable malaria in this region is a real and present threat. Critical actions to prevent further spread of the emerging incurable parasites are: (1) Commitment and real sense of urgency through declaration of a “Public Health Emergency of International Concern” or a similar set of directives; (2) Establish leadership with sufficient authority, respect, expertise and operational funding; (3) Engage affected security forces to stop disease transmission and support elimination operations; (4) Utilize surveillance as a core intervention with result-based funding targeting malaria transmission foci with rapid and effective action. Immediate decisive action is needed in Southeast Asia to prevent the next malaria pandemic. This chapter highlights persistent gaps in the region with methods to address them. In 2015–2016, our collaboration with NIMPE pilot tested tools to intervene in actual forest transmission foci. Our study district saw a 96% decrease in malaria from 2014 to 2017, with the entire province seeing the largest decrease in Central Vietnam in this same timeframe. We describe methods to tackle transmission foci, with both an integrated prevention and treatment package. We call on all stakeholders to make changes to current investments to address this critical challenge

Dynamics of IUD use in Vietnam: implications for family planning services at primary health care level

This study describes the dynamics of intrauterine device (IUD) use in Vietnam and implications for family planning services. A retrospective study was conducted among women who received IUD services in 2006–2009 at six commune health stations in three provinces. Women were interviewed about IUD use and switching behaviors. Of 1316 participants, 12.1% had discontinued IUD use at 12 months after insertion, 19.4% at 24 months, and 26.9% at 36 months. The highest rates of discontinuation were among older women and farmers/manual workers. Among 434 women who had an IUD removed, 49% cited health concerns as the main reason. Following removal, 70% switched to another contraceptive method (n = 306); of these, 15% switched to withdrawal, and 12% waited >2 months before adopting a new method. Dissatisfaction with IUD services was associated with high rates of discontinuation. Early discontinuation, delays in adopting new methods, and switching to withdrawal may contribute to unintended pregnancy among commune health station users in Vietnam

A hierarchical architecture for increasing efficiency of large photovoltaic plants under non-homogeneous solar irradiation

Under non-homogeneous solar irradiation, photovoltaic (PV) panels receive different solar irradiance, resulting in a decrease in efficiency of the PV generation system. There are a few technical options to fix this issue that goes under the name of mismatch. One of these is the reconfiguration of the PV generation system, namely changing the connections of the PV panels from the initial configuration to the optimal one. Such technique has been widely considered for small systems, due to the excessive number of required switches. In this paper, the authors propose a new method for increasing the efficiency of large PV systems under non-homogeneous solar irradiation using Series-Parallel (SP) topology. In the first part of the paper, the authors propose a method containing two key points: a switching matrix to change the connection of PV panels based on SP topology and the proof that the SP-based reconfiguration method can increase the efficiency of the photovoltaic system up to 50%. In the second part, the authors propose the extension of the method proposed in the first part to improve the efficiency of large solar generation systems by means of a two-levels architecture to minimize the cost of fabrication of the switching matrix

Proceedings of the 5th Workshop on BioNLP Open Shared Tasks

We present the approach taken by the TurkuNLP group in the CRAFT Structural Annotation task, a shared task on dependency parsing. Our approach builds primarily on the Turku neural parser, a native dependency parser that ranked among the best in the recent CoNLL tasks on parsing Universal Dependencies. To adapt the parser to the biomedical domain, we considered and evaluated a number of approaches, including the generation of custom word embeddings, combination with other in-domain resources, and the incorporation of information from named entity recognition. We achieved a labeled attachment score of 89.7%, the best result among task participants. </div

A Literature Review of the Project-based Teaching Method in the Education of Vietnam

The teaching method is one of the main aspects to make a huge contribution to the success of any education system, and project-based teaching (PBL) is an important aspect to contribute to the success of education also. This research was conducted through a review of project-based teaching that has been used in the education system of Vietnam, including a sample, and setting that included imperial and theoretical literature selected from the fields of education. Findings show that this method has been applied to various sectors of education, from kindergarten education to higher education, in many disciplines and subjects, in schools and educational settings, and has become more widely popular than ever. This method, however, has its drawbacks because it takes time to master and teachers need more skills to manage the learning atmosphere. This method has been commonly accepted as one that can help teachers and learners understand more and get more benefits in the learning and teaching process
