In this article, since the first days of our country's independence, education issues have been considered as one of the priority tasks of state policy. In this regard, we have thinkers who can be an example to all. We should be proud of this, continue their ways and apply their lessons to life, so that there is no place left to remember that "Japan, South Korea, and Scandinavian countries have advanced in science." Any science-enlightenment directions and ideological potential should serve to increase the nation's science-enlightenment and ability to perform. This is an area that needs to be studied in depth.

PRINCIPLE OF ACQUISITION PRESCRIPTION IN INTERNATIONAL LAW ON SEA AND ISLAND DISPUTE SETTLEMENT: A CASE OF VIETNAM’S SOVEREIGNTY OVER THE HOANG SA AND TRUONG SA ARCHIPELAGOES
Authors:   Institute Of Americas Studies Vietnam Academy Of Social Sciences, Vietnam, Lan Anh Dr. Le
Published: May 2023

There have been many disputes over territorial sovereignty between countries, lasting many years with different viewpoints, principles, and historical shreds of evidence between countries. In order to thoroughly settle territorial disputes between countries, since the Berlin Convention in 1885, most countries in the world, including Vietnam, have agreed to apply the principle of acquiring territory in sovereignty dispute settlement among countries. Establishing a country's sovereignty over territories must be based on the rules of international law on territorial acquisition. It plays an essential role in resolving territorial disputes. Territorial acquisition regulations help address the question of how a state can legally establish sovereignty over a new territory against the claims of other states. These are also the legal principles that Vietnam has relied on to prove and affirm Vietnam's sovereignty over the Hoang Sa and Truong Sa archipelagos in the East Sea.

The concept of recovery in psychiatry has undergone many changes during time, in terms of definitions, characteristics, evaluation and implementation in the mental health systems. Two main forms of recovery have been described in the literature: clinical recovery, which imply clinical and functional aspects and characterizes the medical model of approaching mental disorders, and personal recovery, described as a process of transformation and growth of the person, besides the negative impact of the disorder. Recovery is a multi-dimensional, complex process which develops in stages and is influenced by many internal and external factors. Different frameworks and models of recovery have been described in this research field, in order to offer a basis for implementing the personal recovery perspective in the mental health services and practices.

Introduction: Quality of life is an important parameter that clinicians must take into serious consideration when managing a patient with schizophrenia. It is crucial that more studies are performed in order to extend our knowledge of factors that influence quality of life to better approach treatment in patients with schizophrenia, a chronic, life-time disease. Method: We evaluated patients who met DSM IV or ICD-10 criteria of schizophrenia that were admitted in the “Alexandru Obregia” Psychiatric Hospital in Bucharest between 01.10.2009 – 01.10.2012. This was a prospective non-interventional study assessing quality of life in chronic schizophrenia patients. Our purpose was to evaluate quality of life in patients presenting symptoms of depression measured on the G6 sub-scale of the Positive and Negative Symptoms Scale (PANSS). Descriptive statistics were used to characterize the sample and simple linear regressions were used to assess the impact of depression on quality of life and self-esteem (determined through the Global Assessment of Functioning - GAF, World Health Association - WHO-QOL and Rosenberg Self Esteem Inventory). Results: We included all the patients that did not have any missing data, resulting in a total of 110. Forty-five (14.6%) were males and the mean (standard deviation) age was 40.2 (10.37) years. The mean PANSS G6 score was 3, representing mild to moderate depression. Schizophrenia patients with depression had poorer quality of life, specifically in the physical (p=.002), social relationships (p=.034) and psychological domains (p=.005) of the WHO-QOL It was also related to lower self-esteem (p=.001) as measured by Rosenberg Inventory and had no impact (p=.259) on GAF score. Conclusion: Depression is frequent in schizophrenia and has a negative impact on quality of life. It is important to acknowledge these symptoms and thoroughly treat them in order to improve quality of life in these patients.

High Functional Autism (HFA) in adults, former known as Asperger Syndrome in DSM-IV-TR, was lately included in the wide umbrella of autism spectrum disorders in DSM 5. Asperger Syndrome (AS) is characterized by altered social interactions, restricted interests and repetitive stereotypical behavior just like other types of autism, with the exception of good language development and normal psychomotor and cognitive skills. (1,2) The purpose of this article is to investigate data in current literature about diagnosis, characteristics, functionality, comorbidities, treatment and outcome for adults diagnosed with AS/HFA. Individuals diagnosed with AS have difficulties in finding a job and/or a vocational niche which would secure a financially stable and independent life. They also find it harder to maintain their jobs and social relationships. (6,10) Most of them work jobs far below their skills level as difficulties start with the skills required for a job interview. So, although they are qualified for the job they apply to, they are rejected due to poor abilities to engage in reciprocal conversation or think and quickly respond to questions addressed during a job interview Autism spectrum disorders are frequently associated with comorbidities like: hyperactivity, poor attention and concentration, compulsions, preoccupations, sleep problems, anxiety and fears, depressive mood, tics, etc., all these being features of coexisting neuropsychiatric disorders such as ADHD, affective disorders, obsessive compulsive disorders etc. (22) High Functional Autism is a pathology not so well known and often confounded with others like depression, OCD, psychosis and/or personality disorders. The diagnosis is complicated and an elaborate family and personal history is needed, along with intensive testing and scales. These individuals are precious to society due to their incredible capacity to focus restrictively on an area of interest, so they can have amazing performances if they are guided accordingly. They don't need support only as children but throughout their entire life, and the higher the rate of support, the better the outcome.

We present a case of neuroleptic malignant syndrome (NMS) in a 30-year- old patient receiving treatment with clozapine, amisulpride and clonazepam. NMS is a severe and rare (0.01 – 0.02%) manifestation of antipsychotic drugs presenting symptoms that include mental status changes, muscle rigidity, diaphoresis, hyperthermia and autonomic dysfunction, but also changes in the blood results such as neutropenia, leukocytosis and - more important- serum CK elevation. This kind of condition is more frequent in first generation 'typical' antipsychotics than in second generation 'atypical' antipsychotics and less frequent in other agents (lithium, valproate or non-neuroleptic agents that block central dopamine pathways). Total resolution of the symptoms is obtained in most cases. Mortality reaches 10 – 20% in case the condition is not recognized.

Introduction. The present study comparatively analyzes the hospitalized cases of the Psychiatry acute department of CEHB during the pandemic interval (March 2020-February 2022) to the similar previous time interval, especially from the systemic couple and family psychotherapy point of view. Material and method. The cases were statistically retrospectively analyzed on the basis of hospital informatic applications, correlated to the approved hospital structure, current codification systems, the statement and the values contracted by the health insurance system. Results. There were pandemic specific trends (fewer cases, lower complexity, but higher average patient stay and bad prognosis, sometimes showing unbalance between the effective cost and statement value through the Health Insurance House Bistrita-Nasaud). The psychological impact of the pandemic firmly imposed the relational counseling necessity (increase of 1500%). Other therapies (couple therapy, sexual therapy) were not considered to be useful during the acute hospitalization episode. Conclusions. The specifics of the cases during the pandemic required additional efforts to comply with the assumed indicators (CCI, APT, budget). There was a significant increase in the need of relational counseling. Couple therapy and sexual therapy remained in charge of the private medical system.

Published: May 2023

The level of cognitive impairment in patients with bipolar affective disorder (BD) represents a topic of general interest because it is essential when talking about treatment adherence, quality of life, and global burden of disease. Of the treatments currently available for BD, the most studied mood stabilizer is lithium. The mechanisms and effects that lithium has on cognition are not well known. This study aims to review the current knowledge regarding the levels of impairment or improvement of cognition induced by lithium in patients with BD.
A case of portal vein thrombosis in a patient on clozapine
Authors:   “Prof. Dr. Alexandru Obregia” Clinical Psychiatry Hospital, Bucharest, Romania, Mihalcea Maria
Published: May 2023

Portal vein thrombosis (PVT) is a rare but serious complication that can occur with the use of clozapine, an antipsychotic medication. PVT is characterized by the formation of a blood clot in the portal vein, which is responsible for carrying blood from the gastrointestinal tract to the liver. Clozapine use has been associated with an increased risk of PVT due to its effect on platelet function and the coagulation system. Patients on clozapine treatment who experience symptoms such as abdominal pain, nausea, and vomiting should seek immediate medical attention to rule out the possibility of PVT. We present the case of a 36-year-old man with PVT secondary to clozapine use.
Estimating AGN Black Hole Masses via Continuum Reverberation Mapping in the Era of LSST
Authors: Wang Shu , Guo Hengxiao , Woo Jong-Hak
Published: May 2023

Spectroscopic reverberation mapping (RM) is a direct approach widely used to determine the mass of black holes (BHs) in active galactic nuclei (AGNs). However, it is very time consuming and difficult to apply to a large AGN sample. The empirical relation between the broad-line region size and luminosity (Hβ
R
BLR–L) provides a practical alternative yet is subject to large scatter and systematic bias. Based on the relation between the continuum emitting region size and luminosity (R
CER–L) reported by Netzer (2022), we present a new BH mass estimator via continuum RM (CRM) by comparing R
CER and R
BLR, assuming that the continuum lags are dominated by the diffuse continuum emission. Using a sample of 21 AGNs, we find a tight R
BLR–R
CER relation (scatter∼0.28 dex) and that R
BLR is larger than R
CER at 5100 Å by an average factor of 8.1. This tight relation enables the BH mass estimation based on the CRM combined with the velocity information. Applying the relation to rest objects in our CRM sample, we demonstrate that the predicted R
BLR,CRM follows the existing Hβ
R
BLR–L relation well and the estimated CRM BH masses are consistent with the RM/single-epoch BH masses using Hβ. This method will provide significant applications for BH mass estimation thanks to the short continuum lags and the easily accessible high-cadence, large-area photometric data, especially in the era of Legacy Survey of Space and Time.
A Simple Code for Rotational Broadening of Broad Wavelength Range High-Dispersion Spectra
Authors: Carvalho Adolfo , Johns-Krull Christopher M.
Published: May 2023

In high dispersion spectra of rotating bodies such as stars and planets, the rotation contributes significantly to, and sometimes dominates, the line broadening. We present a simple method for rotationally broadening large wavelength ranges of high-dispersion spectra. The broadening is rapid and scales linearly with the length of the spectrum array. For large wavelength ranges, the method is much faster than the popular convolution-based broadening. We provide the code implementation of this method in a publicly accessible repository.
The Behavior of Bp Si Stars in the Far UV—Paper V: HD 187473
Authors: Monier Richard
Published: May 2023

The analysis of five spectra of the B9 SiSrEu HD 187473 recorded by the Short Wavelength Prime camera on board the International Ultraviolet Explorer reveals large amplitude variations of the far ultraviolet spectral energy distribution over a time interval of about half the rotation period. In contrast, the level of the mid-UV flux does not vary between phases of FUV flux maximum and minimum which suggests that changes of the silicon continuous and line opacity play an important role in the variations. The iron-peak elements, chromium, manganese and iron probably also contribute to these variations.
A Long-lived Lunar Magnetic Field Powered by Convection in the Core and a Basal Magma Ocean
Authors: Hamid Saira S. , O’Rourke Joseph G. , Soderlund Krista M.
Published: May 2023

An internally generated magnetic field once existed on the Moon. This field reached high intensities (∼10–100 μT, perhaps intermittently) from ∼4.3 to 3.6 Gyr ago and then weakened to ≲5 μT before dissipating by ∼1.9–0.8 Gyr ago. While the Moon’s metallic core could have generated a magnetic field via a dynamo powered by vigorous convection, models of a core dynamo often fail to explain the observed characteristics of the lunar magnetic field. In particular, the core alone may not contain sufficient thermal, chemical, or radiogenic energy to sustain the high-intensity fields for >100 Myr. A recent study by Scheinberg et al. suggested that a dynamo hosted in electrically conductive, molten silicates in a basal magma ocean (BMO) may have produced a strong early field. However, that study did not fully explore the BMO’s coupled evolution with the core. Here we show that a coupled BMO–core dynamo driven primarily by inner core growth can explain the timing and staged decline of the lunar magnetic field. We compute the thermochemical evolution of the lunar core with a 1D parameterized model tied to extant simulations of mantle evolution and BMO solidification. Our models are most sensitive to four parameters: the abundances of sulfur and potassium in the core, the core’s thermal conductivity, and the present-day heat flow across the core–mantle boundary. Our models best match the Moon’s magnetic history if the bulk core contains ∼6.5–8.5 wt% sulfur, in agreement with seismic structure models.

Published: May 2023

There have been multiple types of research focusing on the relationship between feed ingredients and metal content in the egg white due to their role in human nutrition. The aim of the present study is to determine the metal concentration in hens’ eggs and, in particular, to compare the metal concentration in egg albumen originating from industrial poultry farms with that of backyard and free-range hens. All samples were collected in Romania from five separate counties and 10 different farms, over a period of two weeks and, as a result, a total of 50 were collected, 10 from each housing system (batteries/cages, litter/soil, free-range, organic and backyard). The measurements of the metals were taken by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), with a wide range of elements reported. For the essential elements, we measured Cr, Cu, Fe, Mn and Zn; Al, Cd, Ni and Pb for the heavy metals and, in addition, we measured B, Ba, Sr, Ca and Mg. The present study revealed that the metals in eggs from free-range hens are richer in essential elements with mean concentrations as follows: 1.528 mg/kg for Fe, 3.278 mg/kg for Zn, 0.058 mg/kg for Mn and 1.362 mg/kg for Cu. We concluded that the egg quality is closely connected with the housing system and nutrition. Furthermore, the results demonstrate that eggs from backyard housing are no better than those from free-range hens in terms of essential metal composition. The heavy and non-essential metal contents, present in the albumen of all the examined eggs, were much lower than the maximum allowed concentration and, therefore, egg consumption does not pose any risk to human health.
Study of the plant growth-promoting capacity of Pseudomonas putida 1046 in a model plant system
Authors: Georgieva Gloria , Nedeva Trayana , Badalova Marina , Deleva Veronika , Savov Valentin
Published: May 2023

Plant Growth Promoting Rhizobacteria (PGPR) represent a microbial community that exerts growth-promoting capabilities in plants by various mechanisms. Among the PGPR genera, Pseudomonas spp. deserves special attention. It is due to its characteristic traits, like the production of phytohormones and siderophores, solubilization of minerals and phosphates, and plant protection from biotic and abiotic stress. These PGPR properties depend on the microorganism and its plant counterpart. The use of microbial strains as bioinoculants must consider the physiological and economic aspects of the process, and the plant growth stimulating effect has to be checked and proved. This study aimed to explore the PGP capacity of Pseudomonas putida 1046 strain in a model plant system of the economically important corn culture (Zea mays). The effect of the strain’s metabolic status on the plant germination capacity was evaluated. Bacterial cultures, grown 16 h and 48 h, were explored for the treatment of the corn seeds at three experimental concentrations: 0.1, 0.2, and 0.4%, and monitoring of their germination capacity through the growth indicators length of the radicle, length of the coleoptile, and the number of lateral roots. The data obtained outline the positive effect of Pseudomonas putida 1046 on the germination capacity of corn when applied at 0.2% concentration. The in vitro treatment of the model plants with 0.2% suspension resulted in a 22.87%–28.33% increase in the length of the radicle, a 35.96%–49.56% increase in the length of the coleoptile, and a 5.41–16.67% increase in the number of the lateral roots. High values of the vigour index (2125 for 16 h and 2721 for 48 h culture) were also registered. The strain’s ability to produce siderophores of hydroximate type and exhibit phosphate solubilizing activity is proved. The optimal treatment parameters of the corn seeds comprise the application of 0.2% suspension of 16 h grown Pseudomonas putida 1046 strain for five days.

The aim of this research has enabled us to establish the influential relationship between factors associated with e-learning, such as individual impact and depression, and the mediating role in psychological distress and computer anxiety related to the fear of failing an academic year in times of COVID-19 in university students at two universities in the Arequipa region of Peru. The methodology used was developed in two stages; in the first stage, an Exploratory Factor Analysis (EFA) was performed, which enabled us to compare the initial results from the theoretical matrix proposed with the observed matrix; in the following stage, a Confirmatory Factor Analysis (CFA) was performed, as an analytic condition for the factors and to determine the robustness of the proposed model. For this purpose, the Structural Equation Modeling (PLS-SEM) was used, based on partial minimum squares. The sample for the study was made up by 252 students. It is concluded that there are significant influential relationships among the variables observed, such as the individual impact of e-learning, depression, mediated by psychological distress and anxiety for fear of failing the academic year.
Intuitionistic fuzzy-based TOPSIS method for multi-criterion optimization problem: a novel compromise methodology
Authors: Qin Ya , Rizk-Allah Rizk M. , Garg Harish , Hassanien Aboul Ella , Snášel Václav
Published: May 2023

The decision-making process is characterized by some doubt or hesitation due to the existence of uncertainty among some objectives or criteria. In this sense, it is quite difficult for decision maker(s) to reach the precise/exact solutions for these objectives. In this study, a novel approach based on integrating the technique for order preference by similarity to ideal solution (TOPSIS) with the intuitionistic fuzzy set (IFS), named TOPSIS-IFS, for solving a multi-criterion optimization problem (MCOP) is proposed. In this context, the TOPSIS-IFS operates with two phases to reach the best compromise solution (BCS). First, the TOPSIS approach aims to characterize the conflicting natures among objectives by reducing these objectives into only two objectives. Second, IFS is incorporated to obtain the solution model under the concept of indeterminacy degree by defining two membership functions for each objective (i.e., satisfaction degree, dissatisfaction degree). The IFS can provide an effective framework that reflects the reality contained in any decision-making process. The proposed TOPSIS-IFS approach is validated by carrying out an illustrative example. The obtained solution by the approach is superior to those existing in the literature. Also, the TOPSIS-IFS approach has been investigated through solving the multi-objective transportation problem (MOTP) as a practical problem. Furthermore, impacts of IFS parameters are analyzed based on Taguchi method to demonstrate their effects on the BCS. Finally, this integration depicts a new philosophy in the mathematical programming field due to its interesting principles.

This manuscript primarily focuses on the nonlocal controllability results of Hilfer neutral impulsive fractional integro-differential equations of order $ 0\leq w\leq1 $ and $ 0 < g < 1 $ in a Banach space. The outcomes are derived from the strongly continuous operator, Wright function, linear operator, and bounded operator. First, we explore the existence and uniqueness of the results of the mild solution of Hilfer's neutral impulsive fractional integro-differential equations using Schauder's fixed point theorem and an iterative process. In order to determine nonlocal controllability, the Banach fixed point technique is used. We employed some specific numerical computations and applications to examine the effectiveness of the results.
Imported fabrics and their social reach in Valencia and its kingdom (14th‑15th centuries)
Authors: García Marsilla Juan Vicente
Published: May 2023

Through both fiscal and notarial records, this study focuses on the role played by imported fabrics in a great late-medieval city such as Valencia. It shows how most of the market was dominated by locally produced fabrics, which in some cases were born from the imitation of these imports. On the contrary, foreign woolen cloths, arrived almost exclusively from Flanders and England, constituted a smaller market to which not only the nobles aspired, but also a relatively large group of bourgeois who used to have a few imported garments for the most important occasions. It cannot be said, in this case, that the international cloth trade is at the basis of the consumption habits of the local population, but rather that it was a very exclusive sector dominated by a few local merchants. Nevertheless, this exclusive sector of imported fabrics was much more important because of the imitation effect in the local textile production, which partly guided the evolution of this industry in Valencia.
Des soieries et des hommes
Authors: Vigouroux Élodie
Published: May 2023

Dès le xive siècle, la langue française, par l’usage des termes « damas » et « damassé », a associé un type de production textile à la ville syrienne du même nom. Pourtant, si les travaux de Colette Establet et Jean-Paul Pascual ont éclairé la fabrication, le commerce et les usages des tissus à Damas au xviie siècle par une fine analyse des archives ottomanes [Establet & Pascual 2005], ces questions restent à explorer pour la période médiévale. La présente contribution, par la mise en perspective du vocabulaire du textile utilisé dans les inventaires princiers, les archives marchandes italiennes, les récits de voyageurs européens, avec des textes narratifs et juridiques en langue arabe permet de jeter les bases d’une étude consacrée à l’évolution de la place des étoffes et des vêtements dans le paysage économique et urbain de Damas du xiiie au xvie siècle.
Le manteau d’Arlotto
Authors: Arnoux Mathieu
Published: May 2023

Recueillies à la fin du xve siècle, les quelque 200 récits rassemblés dans les Motti e Facezie del Piovano Arlotto, sont une source précieuse sur la société florentine. Si elles sont le plus souvent très brèves, l’une d’entre elles (no 111), relative à la rencontre à Rome en 1475 d’Arlotto avec un célèbre humaniste, le cardinal Jacopo Ammannati, est d’une nature différente, par sa longueur, sa construction très soignée et la précision des attaques qu’elle porte contre un membre prestigieux du cercle médicéen. Au-delà de sa probable signification politique, elle est remarquable par les notations qu’elle contient sur la question sociologique du vêtement. Dans une période où se déploie à Florence une nouvelle culture du luxe ostentatoire, les propos et récits d’Arlotto font émerger les règles pratiques et les représentations d’un usage moyen de l’habillement.
Les vêtements des juifs dans les royaumes hispaniques : des marqueurs identitaires ?
Authors: Soussen Claire
Published: May 2023

Alors qu’une « politique du signe » de plus en plus explicite s’affirme en Occident à partir du concile de Latran en 1215 visant à distinguer les juifs et les musulmans des chrétiens, le présent article s’attache à repérer dans la documentation archivistique et iconographique les traces du port de vêtements identitaires par les juifs des royaumes hispaniques à la fin du Moyen Âge. Les mentions de « capes juives » et de rouelles dans la documentation textuelle sont confrontées aux images tirées de la série des haggadot catalanes, tout en usant des précautions méthodologiques nécessaires à l’interprétation des images médiévales pour éviter toute surinterprétation.
A Proposal for Enhancing the Security and Privacy of Digital Currencies
Authors: Takaragi Kazuo , Kubota Takashi
Published: May 2023

Regarding digital currencies, the authors focus on 1) the security issues with the advent of quantum computers and 2) the privacy issues in relation with CBDC's wider collection of personal data. Many legal issues can be solved using technology. Thus, they propose central banks to adopt their privacy-enhancing technologies in cryptography, called “SK4SC,” which performs KYC (know your customer) while keeping PKI (public key infrastructure)-registered trading partners anonymous. Security and privacy in digital currency can be trade-offs. For example, the AML/CFT effort requires the collection of personal information about innocent people, which can be detrimental to their privacy. On the other hand, excessive restrictions on the collection of personal information to protect privacy may weaken the AML/CFT. However, adopting SK4SC can resolve the trade-offs by anonymizing KYC, which is essential for the AML/CFT.

The development of the palm oil industry is followed by the increased amount of lignocellulosic biomass waste. Lignocellulosic biomass waste contains cellulose and hemicellulose which are potential sources of C6 and C5 sugars. C5 or pentose can be hydrolyzed into furfural through the hydrolysis process and then dehydration reaction using the acid catalyst in various kinds of solvent. At this moment, the highest yield of furfural in the acid-catalyzed hydrolysis of xylose in water resulted in only about 50.0w-%. Other methods such as salt addition or the use of various organic solvents lead to new challenges both in purification and environmental issues. Therefore in this study, 70.0w-% ethanol in water was utilized as the solvent in a range of temperatures (140-170°C) and concentration of sulfuric acid (0.1-0.5M) up to 120 minutes reaction time. As the outcomes, the shorter time was needed to achieve maximum furfural yield with the increase of temperature and acid concentration with the water and the ethanol as the solvent. Improvement was shown in the highest furfural yield achieved up to 70.0-72.0mol-% (after 15 min at 170°C, 0.2-0.5 M concentration of H2SO4). The results showed the potential use of ethanol as a green solvent to produce furfural from xylose.
