Plastic litter and microplastic pollution in the aquatic environment have become a major concern since scientists, politicians, and citizens began to learn about the impacts in recent years. This in-depth desk review of scientific papers and Vietnamese policies aims to state the current knowledge, legal framework, and action plan relative to microplastic assessment, release, and control in Vietnamese aquatic environments, especially rivers. Regarding scientific literature, this paper focuses on (i) the occurrence of microplastics in riverine surface water and sediments, (ii) the fate and transfer of microplastics in Vietnam’s canals-riverine- estuarine systems, (iii) their accumulation in biota, and (iv) effects to receiving river basins and human health through ingestion of seafood and salts. This paper also points out and describes the main and current Vietnamese policies on plastic litter, including microplastic, and the control of their release into the aquatic environment. Based on the needs identified from the scientific literature review and the action plan to be implemented in the near future, recommendations are given for both scientists and decision-makers to tackle microplastic pollution and provide a sustainable approach.
THE ROLE OF THE FINANCE POWER IN THE POST-WAR RECONSTRUCTION OF UKRAINE
Authors: BAK Nataliia
Published: August 2023

Introduction. Despite the active military actions, a strategy for the further development of the Ukrainian state is being formed today. The strategy requires a specification of an effective mechanism for accumulating and allocating society's financial resources. Representatives of economic science and specialists of state authorities are working to calculate the quantitative parameters of such a financial mechanism. However, the qualitative characteristics of financial foundations for future social organization remain insufficiently transparent and understandable. Among them, the power factor plays a leading role.

The purpose of the article is to substantiate the theoretical foundations of the role of finance in the post-war reconstruction of Ukraine through the prism of the functioning of the institution of power.

Methods. General scientific and special methods are used: analysis, synthesis, grouping, description, theoretical generalization, and abstract-logical method.

Results. As a result of the study, the necessity of identifying priorities for the development of Ukrainian society and the national economy from the standpoint of the formation and functioning of the centers of financial power is substantiated. These priorities include civil society, public administration institutions, local self-government bodies, business, as well as public and private, real and financial sectors of the economy. Balancing economic interests and capabilities of the centers of financial power requires purposeful changes in the areas of taxation and use of state financial resources, modernization of the real sector of the national economy on an innovative basis, and development of financially capable civil institutions and business communities.

Conclusions. Taking into account the factor of financial power, main directions of the further development of Ukrainian society are democratization of social relations, deregulation and liberalization of economic relationships, decentralization of the process of distribution and redistribution of the GDP value, definancialization and full achievement of the goal of the fiscal decentralization policy.

Purpose: Corruption has a very negative impact. As a crime, corruption not only harms the country's finances and economy, but also hampers the growth and continuity of national development which demands high effectiveness. Methodology: Corruption has eroded democratic values, violated the principles of good governance, and caused discrimination against public services. Corruption has also led to low openness and representativeness in the formulation of policies in the legislature, and even corruption has hampered legal certainty in the judiciary. Results: Corrupt behavior among regional elites still occurs because: 1. System factors, especially regulations related to political recruitment through regional elections, where the weaknesses include our laws that still allow candidates who are suspects in legal cases to run for regional heads, which are further strengthened by the dominance of the ideology of materialism and capitalism that supports these elections, so that the elections still have the opportunity to give birth to corrupt officials, 2. Political actor factors, the low integrity, credibility, and capacity of candidates for regional heads are the biggest contributors to the emergence of corrupt governments, the morality of the candidates is only hunting for the results, namely the seat of power, even though by using all means. The ruling is not to serve the people but to seek material gain.

Published: August 2023

One of the essential functions in the survival of human beings is healthcare. The fraction of total of doctors to inhabitants in established countries is around 1:40, establishing countries 1:1000, however in under-established countries is 0.6 per 1000
inhabitants according to a lot of reviews. IoT is enormously identified as a probable prospect in case of smart healthcare system. A smart manner for decreasing pressure on infrastructure of hospital is monitoring health remotely. This can supervise patients who are non-critical at their home instead of hospitals and healthcare centers. It decreases the pressure on resources of healthcare like doctors and beds for patients. The advantages of remote health monitoring are to give more appropriate medical facil- ity to the people of semi-urban and rural areas and the elderly citizens. But, the ultimatum of the remote healthcare monitoring is the threat of data protection as the sensitive data is stored in a single database, individual sensors adaptation for verifying their correct supervision, correct connectivity link among the patients and the hospital and the device power capability problems. Providentially, these problems are mostly resolvable because of the betterment in the techniques of technology and encryption. Thus, remote health supervision on the basis of IoT have favorable characteristics
which can obtain answers to these problems of the system of healthcare. IoT healthcare systems are established for some of the medical context like management of diabetes, rehabilitation, assisted ambient living (AAL) for elderly persons and others. The main aim of this topic is to explain the working of various applications of monitoring of health and types of healthcare sensing elements utilized on IoT healthcare.

Surrogate-Model-Based Sequential Algorithm for Weather-Dependent Probabilistic Power Flow With High Calculation Efficiency
Authors: Zhang Haochen , Lin Xingyu , Peng Sui , Tang Junjie , ponci ferdinanda , Monti Antonello
Published: August 2023

 Recently, a novel power flow model called weather dependent power flow (WDPF) has been proposed to incorporate conductor temperatures in power flow calculation. It is promising to adopt WDPF model in probabilistic analysis since it provides more accurate electrical and thermal states of a power system. However, calculation of the WDPF model is more computationally expensive than that of conventional power flow model, and hence repetitive calculation of the WDPF in probabilistic analysis is quite time-consuming. To overcome this challenge, a surrogate?model-based sequential algorithm is proposed for calculation of the WDPF model with high computational efficiency and good accuracy. Compared to the method that directly learns the whole WDPF model, the proposed method only learns the power flow sub-model whereas applies a linearization method to solve the thermal resistance sub-model. The construction of the proposed method considers the learning difficulty of the sub-model and the whole WDPF model, thus ensuring the high calculation accuracy. This study is the first to conduct a probabilistic power flow analysis based on the WDPF model. Numerical results in the IEEE 30-bus, 57-bus, and 118-bus systems demonstrate the importance of adopting the WDPF model in probabilistic analysis and the efficacy of the proposed method.
