We reported about study on systematically synthesis of these compounds using heating procedures under different reaction conditions, including microwave-assisted heating conditions at power of 100 W (Procedure A), conventional heating conditions in water bath at 50 °C in acetonitrile (Procedure B), and conventional heating conditions in water bath at 50 °C in DMF (procedure C). The best procedure A was deduced based on the investigations on the reaction conditions. Almost all substituted N-propargyl isatins were new, except compounds with R of H, 5-Me, 5-Cl and 5-Br substituents. The structures of the obtained compounds were confirmed by the modern spectroscopic methods.

However, it is challenging for enterprises, IZs' infrastructure developers, policy-makers and other users to assess the competence of IZs for their location decisions due to the substantial number of IZs, the insufficiency of information of IZs, the lack of suitable and reliable ranking methods and the absence of a ready-made ranking of all IZs in Viet Nam. Thus, there is an urgent need to identify precisely the 'attractiveness' level of the existing IZs based on their own characteristics or in other words, to make a ranking of IZs nationwide. Toward this purpose, this study applied the multi-criteria analysis method to rank the IZs in Viet Nam. This paper is the first ever to successfully conduct a ranking of IZs in Viet Nam with a database constructed at both macro and micro levels, including local economic environment, accessibility, infrastructure, and financial expenses. The ranking is expected to be a useful instrument for enterprises to choose their locations as well as for IZs' infrastructure developers to measure the attractiveness levels of their IZs to develop better business plans. Moreover, it can be used as a basis for policy makers in IZs planning in a more reasonable and scientific manner.

Required 2-chloro-derivatives were obtained from substituted 4-methylquinolin-2(1H)-ones, which were synthesized by ring closing corresponding (un)substituted acetoacetanildes in the presence of ionic liquid [Bmim]OH. The structures of obtained compounds have been confirmed by using spectroscopic methods (IR, NMR and MS).

Therefore, it is necessary to study effective treatments for these types of trauma. This article shows that patients who have had ACL reconstruction surgery in Ho Chi Minh City (Vietnam) had a quite large success rate of 75-95% and their recovery results were very good after ligament reconstruction surgery.

The hypothesis in this paper is proposed that the competitiveness of retail banking services is related to the following factors: service quality, fees, distribution channels, promotion activities, and brand. The data is used from the survey conducted by 438 individual customers who have been using retail banking services in Vietnam’s big cities. This paper shows that the specific factors which are positively impact the competitiveness of retail banking services in Vietnam can be seen as prices (service fees), promotion activities, brand and distribution channels and service quality. The findings in this research could be an academic basis towards the improvement of the policies for retail banking services in Vietnam.

Methods: This mixed-method study used a four-step approach. The first step was a position description content analysis to identify the tasks hospital managers are required to carry out. The resulting data were used to identify the leadership and managerial competency factors and items in the second step. In the third step, a workshop was organized to reach consensus about the validity of these competency factors and items. Finally, a quantitative survey was conducted across a sample of 891 hospital managers who are working in the selected hospitals in seven geographical regions in Vietnam to validate the competency scales using exploratory factor analysis (EFA) and Cronbach's alpha. Results: The study identified a number of tasks required for public hospital managers and confirmed the competencies for implementing these tasks effectively. Four dimensions with 14 components and 81 items of leadership and managerial competencies were identified. These components exhibited 83.8% of variance and Cronbach's alpha were at good level of 0.9. Conclusions: These competencies are required for public hospital managers which provide guidance to the further development of the competency-based training for the current management taskforce and preparing future hospital managers.
