El año 2015 fue importante para Vietnam por tres cuestiones: se cumplió el 40 aniversario de la finalización de la Guerra de Vietnam (1955-1975), el 85 aniversario de la creación del Partido Comunista de Vietnam (PCV), y fue un año políticamente agitado para el país asiático. Por un lado, el PCV fue testigo de una reconfiguración de fuerzas políticas cara a su XII Congreso Nacional, la cual inició con un voto de confianza contra 20 grandes funcionarios del partido en enero de 2015. Por otro lado, la economía vietnamita mostró signos de fortaleza e integración a la economía global al crecer 6.7% su Producto Interno Bruto (PIB), además de negociar y firmar varios acuerdos comerciales con numerosos actores internacionales. Aunado a esto, la política exterior de Vietnam fue marcada por la problemática del Mar del Este (Sur) de China, el reacercamiento con Estados Unidos y la expansión de vínculos bilaterales estratégicos.

Published: May 2023

Mercury is a toxic metal which causes several serious health effects including kidney damage, anxiety depression and peripheral neuropathy, and because of its high volatility assessment in solid samples is problematic. In this study, forty-five samples of local Polish and imported honeys were analyzed by Direct Mercury Analyzer (DMA) for the determination of mercury content. The honey contamination was assessed regarding honey variety and country of origin. Hg level in all tested samples was found to not exceed the 0.81 μg/kg which was below 10% of the applicable law UE limit. Moreover, no statistically significant differences were found in the variety or geographical origin. The study concluded that the Direct Mercury Analyzer (DMA) instrument proved to be an excellent tool for screening mercury in honeys because of its simplicity, rapidity, low detection limit, accuracy and precision and no sample preparation.

Published: May 2023

Background

Millions of people face critical illnesses and need to be hospitalized in an Intensive Care Unit (ICU) annually worldwide. Despite the fact that survival rates of these patients have increased, they develop various cognitive, psychological and functional impairments. This study aims to investigate the significance of the recovery interventions following intensive care unit discharge, the effectiveness of the rehabilitative protocols and their possible deficits.

Methods

MEDLINE (PubMed) and Physiotherapy Evidence Database (PEDro) were searched for studies analyzing the recovery potentials post-ICU among adults, who spent at least 48 hours at the ICU. Methodological quality of the studies was assessed via PEDro Scale.

Results

Nine randomized controlled trials were included. These took place mainly at specialized rehabilitation gyms as well as patients home environments. Studies analyses showed that treatment group showed improvement in functional ability in relation to control group. Nevertheless, differences between two groups were not statistically significant (P<0.05). The majority of studies assessed cardiorespiratory endurance and muscular strength.

Conclusions

The included rehabilitation programs were determined to be effective. Although they didn’t prove any statistically significant difference between groups, quality of life enhancements and stress reduction were reported. Hence, new randomized controlled trials are required in order to provide more accurate data on the potential benefits of rehabilitation strategies among post-ICU patients.

Authors: Duc Hoang Trong , Anh Tu Nguyen , Thi Thuy Nguyen
Published: May 2023

This paper presents new results on dispersion in photonic crystal fibers (PCF) based on a circular lattice, with benzene infiltration into the hollow-core. We achieved near-zero, ultra-flat dispersion through the appropriate adjustment of air hole diameters and pitch of cladding. The result gives a dispersion of ±0.484 ps/nm-1.km over a wavelength range of 450 nm. Besides, we also obtained very high nonlinear coefficients, up to several thousand W–1.km–1, and a very low attenuation, about 10–21 dB/m for optimal structures suitable for supercontinuum generation application.

The prevalence of juvenile obesity is increasing, reaching epidemic proportions, presenting a link not only to NAFLD (non-alcoholic fatty liver disease) but to abnormal lipid profiles and liver enzyme abnormalities. Liver ultrasonography is a sensitive and specific tool for the recognition of NAFLD. This study aims to assess the association between NAFLD and juvenile obesity and to determine the other related changes in a set of indicators, including lipid profile abnormalities and serum transaminases. The sample included 470 obese and 210 non-obese individuals aged 6–16. Anthropometric measures were assessed, with the serum lipid profile and liver transaminases, and abdominal ultrasonography was used to detect NAFLD. Fatty liver was found in 38% of the obese subjects and none of the non-obese subjects. Within obese subjects, mean body mass index (BMI) and waist circumference increased significantly in patients with NAFLD compared to those without fatty liver. Moreover, LDL (low-density lipoprotein), CHOL (cholesterol), and serum liver enzymes were significantly higher in the presence of NAFLD. In conclusion, NAFLD commonly associates with juvenile obesity, relating to obesity and the abnormal lipid profile (including elevated CHOL and LDL) among obese people, reflecting elevated liver transaminases, which increase the risk of cirrhosis.

We used Jones-matrix images of protein networks of blood plasma films obtained from laser autofluorescence and determined the sensitivity, specificity, accuracy, and prognostication of positive and negative results. Our study aimed (1) to develop and substantiate new approaches for the diagnosis of endometriosis by improving the methods of Jones-matrix mapping of laser-induced auto-fluorescence and (2) to develop statistical approaches for analyzing the distribution of values of the true component of Jones-matrix images of blood plasma. Biological preparations were performed for two groups: 35 samples from control group 1 (women with infertility of unknown origin) and 85 samples from group 2 with endometriosis (women with infertility and endometriosis). The strength of the Jones-matrix method of autofluorescence mapping of plasma proteins taken from both groups was maximal for the decisions determined based on the calculation of the statistical moment of the 4thorder, for statistical moment Z4, characterizing the sharpness of the peak distribution of the polycrystalline component of the plasma film. Comparison with the similar informative data of the Jones-matrix laser autofluorescence method of histological sections of the endometrial biopsy under conditions of blind endometriosis diagnosis revealed this method of analysis highly informative. Therefore, this technique can be used in screening studies to form a risk group.

Preeclampsia (PE) is a pregnancy-related disorder that significantly increases the risk of maternal and fetal morbidity and mortality. Melatonin, a potent antioxidant, has been suggested to mitigate oxidative stress and associated damage in various pathological conditions. Placental growth factor (PlGF) plays a vital role in placental development by promoting angiogenesis. This study aimed to investigate whether the levels of melatonin, cytokines, and PlGF were higher in the venous blood of women with preeclampsia during the third trimester of pregnancy compared to those with uncomplicated pregnancies. The study involved 32 women with preeclampsia and 33 healthy pregnant women as a control group. The concentrations of melatonin and PlGF were significantly lower in women with preeclampsia compared to healthy pregnant women. Specifically, the mean level of melatonin in the preeclampsia group was 30.98 pg/ml and 55.20 pg/ml in the control group (p=0.029). Similarly, the mean level of PlGF in the preeclampsia group was 40.03 pg/ml and 213.31 pg/ml in the control group (p<0.0001). This suggests that alterations in the placental production of melatonin and PlGF may contribute to the development of preeclampsia. In contrast, we observed higher levels of the pro-inflammatory cytokine interleukin-6 (IL-6) and the anti-inflammatory cytokine interleukin-10 (IL-10) in the preeclampsia group than in the control group. The mean concentration of IL-6 in the PE group was 270.79 pg/ml, whereas the control group had 224.30 pg/ml (p=0.022). Similarly, the mean concentration of IL-10 in the PE group was 41.90 pg/ml and 30.73 pg/ml in the control group (p=0.018). In women with uncomplicated pregnancies, the interaction between pro-inflammatory interleukine-6 and melatonin can be described by equality of statistical regression.

Published: May 2023

The purpose of the proposed work is to identify similarities and differences in the manifestation of green symbolism in English and German journalistic texts, the sources of which were online media. The subject of the study is the semantics of English and German nouns and verbs representing the green color in the compared languages. The symbolism of this color designation was chosen due to its insufficient study in the framework of comparative linguistics. In this article, based on the material of lexicographic sources, the dictionary meanings of these lexemes are determined, which can display the symbolism of the studied color in journalistic texts in English and German. The scientific novelty of this study is that for the first time it establishes similarities and differences in the transmission of green symbolism through nouns and verbs on the material of modern English and German journalistic texts. It was found that in English texts, in comparison with German texts, a greater number of nouns denoting green are used. In the course of the study, the comparative method, the method of semantic analysis, the modeling method, the quantitative method and the method of component analysis were used. As a result of the conducted research, it was revealed that in English journalistic texts, the symbolism of the green color, represented by nouns and verbs, is used to neutralize the green color of objects of material reality. In addition, the green color is able to display the positive symbolism of the permission of the requested action, environmental protection. In German journalistic texts, the symbolism of the green color can be both positive and negative. Basically, there is a positive symbolism of green when it comes to environmental protection. The symbolism can also be negative when the political activity of the Green Party in Germany is sharply criticized.

Objetivo: Analisar na literatura a influência das técnicas de fotopolimerização na microdureza das resinas compostas. Revisão bibliográfica: O nível de intensidade de um fotopolimerizador pode ser medido através do sistema de MW (megawatt). A partir disso, é possível avaliar sua influência sobre as resinas em termos comparativos de diferentes pontos de vista: diante de técnicas fotopolimerizadoras, luz gradativa, densidade da luz aplicada, comprimento da onda, tempo de exposição e questionamentos acerca da cor da resina em relação a aplicação do fotopolimerizador. A principal abordagem narrativa, trata-se do grau da microdureza e a relação direta desses compósitos sobre o esmalte ao longo do tempo. Dessa forma, deve-se realizar um plano de tratamento viável e personalizado para cada paciente, respeitando suas características anatômicas-estéticas, evitar grande depósitos resinosos, atentar-se da calibração do dispositivo e a distância aplicada, respeitando os limites anatômicos considerados para cada caso. Considerações finais: Estudos da relação do dispositivo fotopolimerizador sobre resinas compostas são necessários para dimensionar a abrangência da dentística. Pois, o mercado odontológico evolui juntamente com a tecnologia, tornando-se uma área relevante e exige atualizações literárias acerca da influência de fotoestimuladores e polímeros e estudos pertinentes sobre a esfera odontológica.

Efficacy of hemoporfin-mediated photodynamic therapy in treating Sturge–Weber syndrome associated port-wine stains: A retrospective study
Authors: Huang Yuanbo , Chen Bin , Yang Jun , Bi Mingye , Bi Linbo , Fan Weixin
Published: May 2023

Background

Sturge–Weber syndrome (SWS) is a rare condition associated with a GNAQ gene mutation, which affects neural crest cells. A pulsed dye laser (PDL) is a first-line therapy for SWS, but its outcomes are worse than those in patients with port-wine stains (PWS). Photodynamic therapy (PDT) is a promising therapeutic option for PWS. However, its use for PWS associated with SWS has rarely been studied.

Aims

To investigate the therapeutic and adverse effects of photodynamic therapy in treating SWS–associated PWS.

Methods

Patients with SWS and matched patients with large size facial PWS were included in this study. Both colorimetric assessment and visual evaluation were conducted to evaluate patients’ responses to treatment.

Results

Colorimetric assessment (blanching rate) and visual evaluation (scores of colour improvement) showed that after two PDT treatments, the SWS and PWS groups had similar treatment responses (21.2% vs. 29.8%; 3.39 vs. 3.65; P = 0.18, P = 0.37). However, there was a significant difference in efficacy between patients with SWS with and without a treatment history (12.4 and 34.9%, respectively; P = 0.02), as well as between patients with lesions located on the central and lateral faces (18.5 and 36.8%, respectively; P = 0.01). Both the SWS and PWS groups experienced minor adverse effects, and the frequency of these effects was not significantly different between the two groups.

Limitation

The study was limited by a small sample size and the possibility of later onset of glaucoma. In addition, false-negative magnetic resonance imaging screening results for SWS could not be ruled out due to the young age of some participants.

Conclusion

Photodynamic therapy is a safe and effective therapeutic option for SWS–associated PWS. Patients without a treatment history, and lesions on the lateral face, responded well, demonstrating good efficacy.
Femtosecond laser-induced desorption of hydrogen molecules from Ru(0001): A systematic study based on machine-learned potentials

Published: May 2023

Femtosecond laser-induced dynamics of molecules on metal surfaces can be seamlessly simulated with all nuclear degrees of freedom using ab-initio molecular dynamics with electronic friction (AIMDEF) and stochastic forces which are a function of a time-dependent electronic temperature. This has recently been demonstrated for hot-electron mediated desorption of hydrogen molecules from a Ru(0001) surface covered with H and D atoms [Juaristi et al., Phys. Rev. B 2017, 95, 125439]. Unfortunately, AIMDEF simulations come with a very large computational expense that severely limits statistics and propagation times. To keep ab-initio accuracy and allow for better statistical sampling, we have developed a neural network interatomic potential of hydrogen on the Ru(0001) surface based on data from ab-initio molecular dynamics simulations of recombinative desorption. Using this potential we simulated femtosecond laser-induced recombinative desorption using varying unit cells, coverages, laser fluences, and isotope ratios with reliable statistics. As a result, we can systematically study a wide range of these parameters and follow dynamics over longer times than hitherto possible, demonstrating that our methodology is a promising way to realistically simulate femtosecond laser-induced dynamics of molecules on metals. Moreover, we show that previously used cell sizes and propagation times were too small to obtain converged results.

Powder bed fusion of metals using a laser beam (PBF-LB/M) is an established additive manufacturing (AM) method that can be used to fabricate geometrically complex NdFe-B magnets. However, the magnetic properties of Nd-Fe-B magnets manufactured by PBF-LB/M are typically inferior to conventionally produced magnets. To overcome this drawback, we modified the surface of the permanent magnet feedstock powder with 1 wt.% surfactant-free Ag nanoparticles (NPs) supporting the formation of relevant phases required for permanent magnetic performance to achieve a suitable micro- and nanostructure after AM. Our study is accompanied by finite element simulations, revealing the impact and dependency of process parameters during PBF-LB/M: a wide temperature field with a high-gradient profile in the front and on the bottom of an overheated region, implying a vast local heating/cooling rate and in-process high thermal stress. We found experimentally that the as-built part density can be affected by both the laser power and scan speed, causing a reduction in density as both parameters increase. The functionality and microstructural properties are also investigated via VSM, HR-SEM, EDX, EBSD, and exemplarily with HR-TEM-EDX and APT. Our study found that modifying MQP-S with Ag NPs increases the coercivity by approximately 20%, which we correlate to a decreased grain size. Additionally, we identified three distinct phases in the modified and unmodified samples, where Ag is primarily found in the intergranular and Nd-rich phases of the as-built parts. Overall, the study's findings contribute to the understanding of the factors that affect the quality and magnetic properties of Nd-Fe-B magnets fabricated through PBF-LB/M and provide valuable insights for further research in this area.

Theoretical Framework: The study of the role of entrepreneurship in reducing poverty has become a major source of interest for scholars and policymakers around the world. A few studies have been conducted by scientists to study the impact of entrepreneurship on poverty reduction. Scholars in fields such as economics and management have tried to explore different approaches in this area and identify the relationships between entrepreneurship and poverty reduction.
 
Design/Methodology/Approach: In this study, we use a deductive approach, in which the hypotheses are tested for application across countries. The quantitative method has been used for this approach. The Panel Fixed Effects model has been employed to assess the impact of entrepreneurship and entrepreneurship development incentives on poverty.
 
Findings: Overall, the results showed that entrepreneurship in countries around the world has a positive and significant impact on poverty reduction. In addition, entrepreneurship development incentives increase the efficiency and capacity of entrepreneurial activities to reduce poverty.
 
Research, Practical & Social implications: This study not only helps to fill the gap in the literature on this topic, but also serves as a model of economic and social development for developed, developing and less developed countries.
 
Originality/value: This is a new study using changes in the HDI to measure poverty reduction, providing a broader and more comparative indicator that answers research questions. This research supports the claim that entrepreneurial activity has impact on poverty eradication and improving human development and people’s quality of life.

Authors: Bhunia Anish Kumar , Shome Mihir Kumar
Published: May 2023

Purpose: The purpose of this article is to increase theoretical knowledge regarding psychosocial antecedents of entrepreneurial intention by explaining the interrelation between personality characteristics and social capital in the formation of entrepreneurial intention.
 
Theoretical framework: The study is a combination of two theories. The first one is the personality approach(trait approach) of entrepreneurship(Chye Koh, 1996) and the second one is the social capital approach of entrepreneurship (Nahapiet & Ghoshal, 1998)
.
Design/methodology/approach: The study is based on secondary data collected by a review of the literature from journals in the disciplines of entrepreneurship, business and management, psychology, and sociology.
 
Findings: This article establishes the interrelationships between three major entrepreneurial personalities (Need for Achievement, Locus of control, and Innovativeness) and social capital in forming entrepreneurial intentions by presenting five major propositions which led to building a conceptual framework.
 
Research, Practical & Social implications: The theoretical implication of this study is that the conceptual framework presented in this article may be used to guide empirical investigations on entrepreneurial intention in the future.
 
Originality/value: This study theoretically demonstrates how personality characteristics and social capital interactively form entrepreneurial intention through a conceptual framework.
Determinants of the Quality of Financial Reports
Authors: Anto La Ode , Yusran Indha Novitasari
Published: May 2023

Purpose: This study aims to determine the effect of the internal control system, information technology, applying of accounting standards, human resources competence, and the role of internal auditors on the quality of financial reports of local governments.
 
Theoretical framework: Internal control system, information technology, applying of accounting standards, human resources competence, and the role of internal auditors affect the quality of financial reports.  According to the agency theory, the quality of financial reports improves government performance and increasing accountability by reducing the information asymmetry. Additionally, under the agency theory approach, transparency and information are useful in controlling managers and making them responsible for their decisions, as well as overall organizational performance.
 
Design/Methodology: The sample in this study was 126 respondents who were obtained using purposive sampling technique from the financial management and accounting officials of Kendari City, Southeast Sulawesi Province, Indonesia. The analytical method used is multiple linear regression analysis.
 
Findings: The results support the agency theory and found that the internal control system, information technology, applying of accounting standards, and the role of internal auditors had a positive and significant effect on the quality of financial reports of local governments. Meanwhile, human resource competence has a positive but not significant effect on the quality of financial reports of local governments. This shows that the better the internal control system, information technology, applying of accounting standards, and the role of internal audit, the quality of local government financial reports will be better.
 
Research, Practical & Social implications: This study can fill gaps in the results of previous research and helps to provide useful information for local governments in improving the quality of financial reports as an important part of efforts to increase transparency and accountability in the management and reporting of local government finances.
