Authors: Ren Lu , Lin Hongfei , Xu Bo , Zhang Shaowu , Yang Liang , Sun Shichang 
Published: July 2021

Background
As a common mental disease, depression seriously affects people’s physical and mental health. According to the statistics of the World Health Organization, depression is one of the main reasons for suicide and self-harm events in the world. Therefore, strengthening depression detection can effectively reduce the occurrence of suicide or self-harm events so as to save more people and families. With the development of computer technology, some researchers are trying to apply natural language processing techniques to detect people who are depressed automatically. Many existing feature engineering methods for depression detection are based on emotional characteristics, but these methods do not consider high-level emotional semantic information. The current deep learning methods for depression detection cannot accurately extract effective emotional semantic information.

Objective
In this paper, we propose an emotion-based attention network, including a semantic understanding network and an emotion understanding network, which can capture the high-level emotional semantic information effectively to improve the depression detection task.

Methods
The semantic understanding network module is used to capture the contextual semantic information. The emotion understanding network module is used to capture the emotional semantic information. There are two units in the emotion understanding network module, including a positive emotion understanding unit and a negative emotion understanding unit, which are used to capture the positive emotional information and the negative emotional information, respectively. We further proposed a dynamic fusion strategy in the emotion understanding network module to fuse the positive emotional information and the negative emotional information.

Results
We evaluated our method on the Reddit data set. The experimental results showed that the proposed emotion-based attention network model achieved an accuracy, precision, recall, and F-measure of 91.30%, 91.91%, 96.15%, and 93.98%, respectively, which are comparable results compared with state-of-the-art methods.

Conclusions
The experimental results showed that our model is competitive with the state-of-the-art models. The semantic understanding network module, the emotion understanding network module, and the dynamic fusion strategy are effective modules for depression detection. In addition, the experimental results verified that the emotional semantic information was effective in depression detection.

ABSTRACT

Objectives
To compare the root resorption resulting from miniscrew-supported maxillary posterior dentoalveolar intrusion using two different force magnitudes.

Materials and Methods
Adult patients with skeletal open bite, indicated for maxillary posterior dentoalveolar intrusion, were recruited and randomly assigned to the comparison or intervention groups. The comparison group involved applying 200 g of intrusive force per segment, which measured 20 g per root, while this force was 400 g per segment in the intervention group, measuring 40 g per root.

Results
Twenty participants were included in the final analysis after 2 patients dropped out, 1 in each group, to end up with 10 subjects (200 roots) per group. There was statistically significant root resorption of 0.84 ± 0.96 mm and 0.93 ± 1.00 mm in the comparison and the intervention groups, respectively. However, there was no statistically significant difference between the groups.

Conclusions
Root resorption inevitably took place in association with orthodontic intrusion. However, increasing the magnitude of the intrusive force did not increase the amount of root resorption, either statistically or clinically.

LE SYSTÈME JURIDIQUE UNITAIRE À L’EPREUVE DU DROIT COUTUMIER : LA NÉCESSITÉ D’UNE TERRITORIALISATION DU DROIT
Authors: GUÉMAR Carine 
Published: July 2021

The unitary legal system vs. customary law: the need of territorialization. The French State is a unitary State as opposed to federal States, in which there is one Constitution providing for provisions applicable throughout the territory of the French Republic. Unity can be found in a legal unity first, in this the unitary Law is the one that does not admit of territorial differenciation. A political and organic unity, since there is only one Parliament, one Government. A social unity eventually, which consists of the admission of a single French people. If the French tradition is based on a centralized system, the implementation of the process of territorial decentralization led to reconsider the uniformity of the Law precisely with the question of territorial differenciation and territorialisation of Law. The present study proposes to return to the consideration by unitary Law of local territories including the overseas territories with the problem of reconciling such a system with customary Law.

Abstract
Untreated coking effluent presents a great challenge for sustainable development of the steel industry and environment preservation. In this study, an internal micro-electrolysis method using Fe/C materials was employed for pretreatment of real coking wastewater with high mass concentration. The Fe/C materials were prepared by Fe powder and graphite powder; and the characteristics of surface morphology, structure, composition of the synthesized materials were examined by Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Energy Dispersive X-ray Spectroscopy (EDS). The effects of factors namely dosage of Fe/C material, treatment time, initial pH and temperature were investigated via chemical oxygen demand (COD) and phenol removal efficiencies. Optimal treatment efficiency was attained at pH of 4, Fe/C dosage of 40 g/L, treatment time of 360 minutes and temperature of 25°C. After the internal electrolysis process, the values of COD, BOD5, and phenol of the wastewater were 6500, 4850 and 0.1 mg/L, respectively.

Abstract
The objective of this paper is to present the investigations of the heat transfer process carried out by means of the multi-ribbon mixer. It is shown that the heat transfer process for the synergic effect of the mixing process and the flowing liquid through the mixer has significantly higher values of the heat transfer coefficients than the mixer with motionless impellers. The empirical correlations between the heat transfer coefficient and the operational parameters obtained in this work can provide guidance for the design and operation of an apparatus equipped with the multi-ribbon impeller. These empirical correlations can be used to predict the heat transfer coefficient for the multi-ribbon mixer.

Authors: Kaliszewski M. , Zgrzebnicki M. , Kałamaga A. , Pinjara S. , Wróbel R.J. 
Published: July 2021

Abstract
The carbonaceous precursor was obtained via pyrolysis of commercial aramid polymer (Kevlar). Additionally the precursor was activated at 1000°C in CO2 atmosphere for different times. Obtained materials were characterised by BET; XPS; SEM and optical microscopy. The sorption capacities were determined by temperature swing adsorption performed in TGA apparatus for CO2 and C2H4 gases. The obtained materials exhibit high difference in sorption of these gases i.e. 1.5 and 2.8 mmol/g @30°C respectively and high SSA ~1600 m2/g what can be applied in separation applications. The highest uptakes were 1.8 and 3.1 mmol/g @30°C respectively. It was found that the presence of oxygen and nitrogen functional groups enhances C2H4/CO2 uptake ratio.
Application of an Artificial Neural Network and Multiple Nonlinear Regression to Estimate Container Ship Length Between Perpendiculars
Authors: Cepowski Tomasz , Chorab Paweł , Łozowicka Dorota 
Published: July 2021

Abstract
Container ship length was estimated using artificial neural networks (ANN), as well as a random search based on Multiple Nonlinear Regression (MNLR). Two alternative equations were developed to estimate the length between perpendiculars based on container number and ship velocity using the aforementioned methods and an up-to-date container ship database. These equations could have practical applications during the preliminary design stage of a container ship. The application of heuristic techniques for the development of a MNLR model by variable and function randomisation leads to the automatic discovery of equation sets. It has been shown that an equation elaborated using this method, based on a random search, is more accurate and has a simpler mathematical form than an equation derived using ANN.

Authors: Burak Samsul M. 
Published: July 2021

AbstractEnergy efficiency has become more important in every industry and daily life. Designing and building a more efficient marine vehicle can lead to lower fuel consumption and a longer lifetime for the components of the vehicle.Erosion caused by cavitation reduces the service life of the propeller and the related components in the propulsion and maneuvering system. Reducing cavitation leads to a longer life for these components. This paper aims to explain and investigate propeller blade cup as a cavitation reduction method for marine propellers. A cavitating no-cup propeller is created and analyzed then the cupped version of this propeller is generated and analyzed to compare with the no-cup propeller. Cavitation results of these propellers are investigated. In addition, the thrust, torque, and efficiency of the propellers are compared.

Abstract
The study on strategic factors and internationalization of small medium enterprises (SMEs) has continued to gain attention across the globe as most indigenous organization desire to take their products and services to international markets. As such, this study tried to ascertain the influence of the strategic factors element of the early internationalization process and tendencies of firms going to foreign market within the period of one to five years which signifies early internationalization. Two different objectives emanated from that main goal: The first is to investigate the influence of firm orientation on early internationalization mode, and the second is to assess the relationship between early internationalization strategies and success of SMEs. Two hypotheses were tested in line with the objectives through the data collected from purposively selected twenty companies in various industries through standardized questionnaires. Both descriptive and inferential statistics was explored to evaluate the hypotheses and variable relationships. The findings reveal that strategic factors significantly affect internationalization of firms when organization put into consideration both external and internal factors towards internationalization, it further shows relationship exist between the factors and what affects SMEs from going global. The study finally recommends that SMEs should consider strategic factors as it will help them to avoid pitfalls while going international.

Food Security in the Era of Sustainable Organic Farming: A Comparison Between the Visegrad Group and India
Authors: Bhagat Priya Rani , Magda Róbert 
Published: July 2021

Abstract
The agriculture industry has undergone many developments that embraced automation, agro-chemical fertilizers, genetically modified organisms etc that brought exponential growth in productivity post industrial revolution. This growth resolved the food availability issues on a global scale, but rapid climate change has brought about a shift in production practices to more sustainable organic farming techniques from the conventional methods. The climate change effects and increase in greenhouse gas emissions adversely affected the overall agricultural output. The widespread perception is that adoption of organic farming can reduce the harmful greenhouse emissions and be less damaging to the environment, although expecting the same level of productivity as conventional farming is challenging. This gradual shift can cause future food security problems such as availability and affordability of food in developing countries. This article compares and analyses such trend in the Visegrad group (V4) and India. The comparison between a group of developed nations and a developing nation is of exploratory interest because V4 countries are regarded as high-income countries and they are leaders in organic cultivation practices since the 1980s, whereas India as a developing country has seen substantial conversion of agriculture land area from conventional to organic farming in the past decade.
Impact of Tax Policy on the Business Economy

Published: July 2021

Abstract
Taxation and tax policy are relatively much-discussed topics within every society, and this has been so in the past, it is today, and it will be in the future. This is mainly due to the fact that no person or company is too fond of having to pay a certain part from their funds to the state in the form of taxes. Each state chooses its own tax policy and its own tax system so that the specified tax policy does not impede economy and economic development, but on the contrary, supports the business and economic growth. After the accession of the Slovak Republic to the European Union, Slovakia had to accept a certain state of tax regulations and rules that was valid in the European Union. This was mainly in order to use the common European market. The Slovak Republic has created its tax system in accordance with the rules of the European Union and has been trying to find a compromise between the amount of taxes necessary for the fulfilment of the state budget and the amount of taxes that would be most acceptable for the business sector and for people. Within the tax system, the Slovak Republic divides taxes into direct and indirect taxes, direct taxes imposed on labour, income and property, and taxes on consumption by indirect taxes. Recently, the prevailing opinion is that taxation should gradually shift from direct taxes to indirect taxes, to motivate people and businesses to achieve the best possible results, and subsequently raise the necessary funds based on the increased consumption. Recently, both in Slovakia and in the European Union, new excise taxes have been increasingly introduced. Traditional excise taxes such as taxes on mineral oils and fuels, tobacco and alcoholic beverages are complemented by energy, environmental, and electronic taxes. Slovakia and the European Union want to reduce the burden on the environment through these taxes on the one hand, and on the other hand, they must respond to the new challenges of globalization, information, and communication.
