    Hlavním cílem bakalářské práce je institucionální analýza bankovních reforem ve Vietnamu. Autor analyzuje vliv bankovních reforem na vývoj institucí. Moderní instituce vyžadují flexibilní a efektivní pravidla, jak formální tak i neformální. Tudíž právní rámec je též součástí analýzy. Autor zkoumá, zda de jure právní rámec odpovídá de facto právnímu rámci. Liberalizace a inter- nacionalizace vietnamské ekonomiky má velký vliv na vývoj bankovního sek- toru. Ačkoliv instituce jsou právně dobře definované, jejich efektivnost je ne- dostačující z důvodu nedostatečné vymahatelnosti práv, nedůvěře a korupci v bankovním sektoru. Vietnam si vybralo správný směr své transformace. Musí však brát na zřetel, že tvorba efektivních institucí jde ruku v rukou se změnou neformálních pravidel. Jelikož difuze informací je limitováno nedostate`enou kodifikací právních norem, konexe a neformálních pravidla hrají velkou roli v bankovním sektoru. Neformální pravidla jsou hluboce zakořeněna a proto bude těžké je změnit v krátkém časovém horizontu. 1The main goals of the bachelor thesis is an institutional analysis of the banking reform in Vietnam. The author analyzes how the banking reform influences the institutional development. Modern institutions require flexible and efficient rules, both formal and informal. Hence, a legal framework is analyzed as well especially as to whether the de jure banking legal framework corresponds with the de facto one. Liberalization and internationalization of Vietnamese economy has a big impact on the development of the banking sector. Albeit institutions are de jure well developed they are not sufficiently efficient due to the inability of enforcement of laws, lack of confidence, and corruption in the banking sec- tor. Vietnam has chosen the right direction but the establishment of efficient institutions has to go hand-in-hand with the change of informal rules. Since the diffusion of information is limited due to lack of codification of laws, connections relationship and informal rules play a crucial role in the banking sector. Infor- mal rules are deeply entrenched and tenacious, and hence difficult to change in the short time. 1Institute of Economic StudiesInstitut ekonomických studiíFaculty of Social SciencesFakulta sociálních vě

    Increasing the Level of Agreement of Taxpayers on Tax Audit Conclusions-Recommendations to Vietnamese Tax Authorities

    Get PDF
    A person’s agreement on a decision usually attaches to their own benefits. However, in most situations, a single decision will impact on different people with different benefits, therefore, a person’s judgment regarding fairness will decide their agreement. Basing on the fact that tax audit conclusions usually impact on economic benefits of taxpayers and a theory of “awareness of fairness”, we would like to apply the quantitative method to identify and verify different drivers of taxpayer’s agreement on tax audit conclusions by assessing reliability and suitability of different scales; verifying research model and research hypothesis, and determining drivers’ impact through questionnaires given to 256 firms. As a result, we propose recommendations to Vietnamese tax authorities in terms of restructuring procedures, completing auditing method and enhancing tax supervising activities in order to increase the level of agreement of taxpayers on tax audit conclusions, improving Vietnamese tax audit effectiveness.

    Introduction: This publication is the product of  research developed within the research lines of the Smart Sensing, Signal Processing, and Applications (3SPA)  research  group  throughout  2018,  which  supports  the  work  of  a  doctor’s degree at VNU University of Engineering & Technology, Vietnam. Problem: The limitations of diagnostic ultrasound techniques using echo information has motivated the study of new imaging models in order to create additional quantitative ultrasound information in multi-model imaging devices. A promising solution is to use image sound contrast because it is capable of detecting changes in diseased tissue structures. Ultrasound tomography shows speed-of-sound changes in the propagation medium of sound waves. This technique is primarily used for imaging cancer-causing cells in womens’ breasts. The Distorted Born Iterative Method (DBIM), based on the first-order Born approximation, is an efficient diffraction tomography approach. The compressed sensing technique is utilized for DBIM to obtain the high-quality ultrasound image, although the image reconstruction process is quite long. Objective: The objective of the research is to propose an combined method for the efficient ultrasound tomography. Methodology: In this paper, we proposed an approach to enhance the imaging quality and to reduce the imaging time by applying the compressed sensing technique along with the multi-resolution technique for the DBIM. Results: The simulation results indicate that the imaging time is reduced by 33% and the imaging quality is improved by 83%. Conclusion: This project seeks to propose an improvement in ultrasound tomography. The simulated results confirmed the realibility of the propsed method. Originality: Through this research, a combined method of compressed sensing and multiple resolution are formulated for the first time in ultrasound tomography. Limitations: The lack of experiments to confirm the proposed method.Introducción: esta publicación es el producto de la investigación desarrollada dentro de las líneas del grupode investigación Detección Inteligente, Procesamiento de Señales y Aplicaciones (3SPA, Smart Sensing, Signal Processing, and Applications) a lo largo de 2018, que respalda el trabajo de un doctorado en la Universidad deIngeniería y Tecnología de VNU, Vietnam.

    Three simple, rapid, sensitive and accurate extractive-spectrophotometric method for the determination of ciprofloxacin in pharmaceutical preparation has been developed. These methods are based on the formation of yellow ion-pair complexes between the examined drug and three sulfonephthalein  acid dyes, namely; bromophenol blue (BPB), bromocresol green (BCG),  and bromothymol blue (BTB) in  acidic medium. The formed complexes were extracted with chloroform and measured at 420, the colored chromogen was stable for twenty four hours. The effect of optimum conditions via pH, dye concentration, time and solvent are studied. Beer’s law is obeyed in the concentration ranges 0.50-25.0 μg/mL with  molar absorptivity of 1.46´104, 1.83´104 and 2.07´104 L. mol-1. cm-1 and limit of detection (LOD) of 0.105, 0.101, 0.084 for BPB, BCG and BTB methods, respectively. No interference was observed from common excipients present in pharmaceutical formulations. The proposed method has been applied successfully to determine ciprofloxacin in pharmaceutical preparation (tablets, infusion and eye drops). Keywords.
