It asserts that contracts, established by parties in a legal transaction, serve as independent foundations for initiating, modifying, or terminating legal relations. The terms of civil contracts create distinct mechanisms for rightful termination, aligning with legal models for the occurrence of right-terminating legal facts. The author highlights the dependency of contractual obligations on the lawful intent of the involved<br>party or objective circumstances, prescribed by the legal model in the contract. When these<br>models align with actual events, they lead to the realization of parties' expectations and the<br>termination of obligations. These legal facts contribute to the regulatory function of the law,<br>ensuring the fair exercise of rights and interests as defined in the contract.

However, foreign investors, in their investment activities in Vietnam, have engaged in "transfer pricing," leading<br>to revenue loss for the Vietnamese budget. Transfer pricing is not a new phenomenon in today's economic development; as early as 2012, certain FDI enterprises, like Coca-Cola, Pepsico, Adidas, and Metro, were suspected of engaging in transfer pricing due to continuous reported losses while expanding their business operations. Vietnam has gradually recognized and adjusted transfer pricing activities. Currently, the legal framework for combating transfer<br>pricing is primarily stipulated in Decree 132/2020/ND-CP, which regulates tax management<br>for enterprises with related-party transactions (hereinafter referred to as Decree 132/2020/NDCP). This article analyzes the nature of transfer pricing and its impact and proposes improvements to the relevant legal provisions on control “transfer pricing”.</span> </p> Thi Hoang Oanh Nguyen Copyright (c) 2023 Tập san Khoa học và kỹ thuật trường Đại học Bình Dương https://jst.bdu.edu.vn/index.php/jst/article/view/196 Thu, 28 Mar 2024 00:00:00 +0700 Legal Transfer in the Common Law World https://jst.bdu.edu.vn/index.php/jst/article/view/197 <p><span class="fontstyle0">This article delves into the intricate evolution of English Law outside of England, spanning centuries of dynamic development. The overarching aim is to comprehensively understand the trajectory of English Law outside its place of origin and evaluate its profound impact on the legal structures of diverse countries. Despite its global influence, the historical development of English law outside England poses challenges for scholars and practitioners. The diversity of interpretations across different jurisdictions, compounded by the evolution of English law over time, complicates efforts to construct a comprehensive understanding of its full scope. This article navigates the multifaceted journey of English Law outside of England, shedding light on its impact on legal systems worldwide. Through an exploration of common law and its challenges, as well as a comparison with civil law systems, the article aims to provide a nuanced understanding of the global legal landscape shaped by English legal principles.</span> </p> Ravinder Kumar Copyright (c) 2023 Tập san Khoa học và kỹ thuật trường Đại học Bình Dương https://jst.bdu.edu.vn/index.php/jst/article/view/197 Thu, 28 Mar 2024 00:00:00 +0700 State management responsibilities in medical examination and treatment activities https://jst.bdu.edu.vn/index.php/jst/article/view/198 <p><span class="fontstyle0">Medical examination and treatment activities play a very important and necessary<br>role in human life. Through medical examination and treatment activities, we will be able to<br>diagnose and treat diseases, thereby helping to maintain and protect human health. However,<br>this is also an activity that carries many hidden risks if it is not performed in a way that ensures compliance with professional requirements and business processes. Therefore, state<br>management of this field is very important and necessary. This not only contributes to<br>improving the efficiency of medical examination and treatment activities, but also minimizes<br>the risks that may arise. Starting from there, the article focuses on analyzing, evaluating and<br>clarifying a number of legal regulations governing the state's management responsibilities in<br>medical examination and treatment activities, while also pointing out limited issues,<br>inadequacies in regulations and law enforcement on this issue and from there, some<br>recommendations for improvement are made.</span> </p> Thi Hong Tam Pham Copyright (c) 2023 Tập san Khoa học và kỹ thuật trường Đại học Bình Dương https://jst.bdu.edu.vn/index.php/jst/article/view/198 Thu, 28 Mar 2024 00:00:00 +0700 Table of Contents https://jst.bdu.edu.vn/index.php/jst/article/view/207 <p>Table of contents</p> Duc Quy Vu Copyright (c) 2024 Tập san Khoa học và kỹ thuật trường Đại học Bình Dương https://jst.bdu.edu.vn/index.php/jst/article/view/207 Thu, 28 Mar 2024 00:00:00 +0700 Employing artificial neural networks for the assessment of the aqueous solubility of drug –like substances https://jst.bdu.edu.vn/index.php/jst/article/view/204 <p><span class="fontstyle0">This research has advanced Quantitative Structure-Property Relationship (QSPR) models for predicting the aqueous solubility of drug-like substances.

The artificial neural network regression model<br>(QSPRANN), derived from selected descriptors of the multivariable linear regression model<br>(QSPRMLR), demonstrated enhanced predictive capabilities for logS values in both validation<br>and prediction groups, yielding SE values of 0.786 and 0.808, respectively. The QSPRANN<br>significantly improved the overall predictability of the multivariate regression model. Statistical assessments of the QSPRANN model revealed SE = 0.699, R2train = 0.918, and Q2v = 0.878.
