The evaluation of gingerol as medical entities in Iraq and Jamaica cultivatedginger was done in this experiment. Two different types of cultivated ginger(Iraq and Jamaica) of the same species (Zingiber officinal) were extracted toachieve the subject of this study. Extraction was performed by two differentstages: the first stage preparative and extraction. Harvested ginger was preparedfor extraction by wash, denotation, drying, grinding, and extracting by acetoneunder heating. The second stage is separation by two steps via TLC and HPLC.The quality and quantity of oleoresin and gingerol in each step of separationwere checked by spots diameter and RF value of spot migration in TLC gingercompounds and quality of whole extract and number of peak in HPLC as well asquantity of gingerol after HPLC separation was done for both Iraqi and Jamaicaginger. The results of comparison between cultivated ginger of Iraq and Jamaicashowed significant decrease (P<0.05) in quantity of extracts and spot diameterof oleoresin where as no significant change (P<0.05) in gingerol quantities byHPLC separation was found in Iraqi species. These results showed no effect ofdifferent cultivation conditions of both peak Jamaica and Iraq species onmedical entities of ginger content of gingerol.

In agricultural production, weed removal is an important part of crop cultivation, but inevitably, other plants compete with crops for nutrients. Only by identifying and removing weeds can the quality of the harvest be guaranteed. Therefore, the distinction between weeds and crops is particularly important. Recently, deep learning technology has also been applied to the field of botany, and achieved good results. Convolutional neural networks are widely used in deep learning because of their excellent classification effects. The purpose of this article is to find a new method of plant seedling classification. This method includes two stages: image segmentation and image classification. The first stage is to use the improved U-Net to segment the dataset, and the second stage is to use six classification networks to classify the seedlings of the segmented dataset. The dataset used for the experiment contained 12 different types of plants, namely, 3 crops and 9 weeds. The model was evaluated by the multi-class statistical analysis of accuracy, recall, precision, and F1-score. The results show that the two-stage classification method combining the improved U-Net segmentation network and the classification network was more conducive to the classification of plant seedlings, and the classification accuracy reaches 97.7%.

Mobile money is an electronic wallet service that allows users to store, send and receive money using their mobile phone. This research is an effort to find out the adoption and utilization of mobile money services in small sized enterprises located in Gaborone, Botswana. Inevitably, other aspects such as different types of transactions carried out using mobile money services in small business, customer’s perception on quality of mobile money service providers, impeding factors of mobile money adoption are also studied for wider understanding of the subject. The findings of the study show that small enterprises use mobile money services to carryout transactions but the level of adoption is not significant. The study revealed that transactional costs and connectivity issues are major barriers of adoption of mobile money services. In conclusion the study recommended that the service providers must improve the connectivity issues and reduce transaction charges in order to increase the utilization of mobile money services

Currently, a significant number of definitions of terms of different types of economy, including the term «new economy», has been developed, and the content of these definitions is often duplicated or not specific. Vertical and horizontal interrelations of these terms are not often expressed clearly, which reduces the quality of scientific researches in the field of economics and management. The subject of the study is the typology of the term “new economy” and related terms. The purpose of the study is clarification and addition of the typology of the term “new economy” and related terms, as well as to develop their adequate definitions. The hypothesis of the study is based on the fact, that the definitions of the studied terms include duplicate components and classification features or do not contain the necessary components and classification features. Therefore, these definitions can be refined and supplemented on the basis of terminological analysis. Logical-structural methods have been chosen as research methods: terminological analysis, grouping, typology and classification. The major components and classification features of definitions of different types of the economics have been revealed and grouped in the article. Classification features and their combinations have been substantiated. Options for the classifications of different types of economics have been developed and their structure has been justified. The basic and refined definitions of different types of economics have been proposed. The scientific contribution has been provided by the correct choice and use of the empirical base, application of adequate research methods, the substantiation of the author’s typology of terms of different types of economics, allowing to obtain their unambiguous definitions.The results of the study allow to adjust a number of provisions of the economics theory, ensuring the improvement of its terminological apparatus and structure.

The subject of this research is the criteria for the effectiveness of social reportage. The goal of this work consists in development of an algorithm for assessing social journalism materials. The article examines the concepts of &ldquo;effectiveness&rdquo; and &ldquo;social TV reportage&rdquo;, as well as the key criteria for assessing social live broadcast on regional television. Quality assessment criteria for live TV broadcast include the following: topic selection, choice of interlocutors and locations; staginess (content of questions, their wording, composition of reportage), work on camera (freedom of behavior of the reporter; language and style of presentation: speech technique, speech culture, sense of screen time). The criteria for the effectiveness of social live television broadcast include solution of the discussed problem ; a promise given by the parties responsible for its solution; a promise to think the problem over; full or partial admission of the problem by the competent persons; rejection of the fact that the problem exists. An attempt to develop the algorithm for assessing social live television broadcasts and its testing would allow improving forms of presentation of the materials and increasing the interest of mass media target audience, which defines the scientific novelty and relevance of this work. The research consists of several stages: the first stage is an attempt to develop the algorithm for assessing effectiveness of social live television broadcasting; the second stage marks their classification by the type social problems; the last stage implies analysis of the quality of social reportage. Conclusions are formulated on the algorithm for analysis of social live television broadcasts.

The human factor within organizations is exposed to different types of risks, especially those that cause damage to their physical and psychological health, which if not identified and treated in time can generate irreversible damage to them. In recent years, investigations have been carried out that address the subject, in which different instruments have been implemented to identify and evaluate this phenomenon, so the purpose of this systematic review article was to analyze the instruments that allow identifying the factors of Psychosocial risks at work (FPR) in Latin America. The information search included databases on the web, such as Redalyc, Dialnet, Scielo and ProQuest. Three people independently selected the articles for review, in a period from 2015 to 2020, where the methodological quality of each of them was evaluated, as well as the inclusion and exclusion criteria considered for the research. It was observed that in recent years different methods and instruments have been implemented to evaluate this phenomenon from different areas, so it is important to determine which are the optimal instruments to identify FPR in workers.

It is well known that the large deviations from stoichiometry in iron sulfide compounds, Fe1-xS (0≤x≤0.125), are accommodated by iron vacancies which order and form superstructures at low temperatures. Although the ordering of the iron vacancies has been well established, the modes of vacancy ordering, hence superstructures, as a function of composition and temperature are still the subject of much controversy. This investigation gives direct evidence from many-beam lattice images of Fe1-xS that the 4C superstructure transforms into the 3C superstructure (Fig. 1) rather than the MC phase as previously suggested. Also observed are an intrinsic stacking fault in the sulfur sublattice and two different types of vacancy-ordering antiphase boundaries. Evidence from selective area optical diffractograms suggests that these planar defects complicate the diffraction pattern greatly.

Governance Quality

The objective of this paper is an attempt to explain the determinants of the lowest governance quality level in one of the communes of the Opolskie Province, Poland. The first stage of the research consisted in developing a commune-level governance quality index in order to measure the quality of governance in the 60 communes of the Opolskie Province. Subsequently, the commune with the lowest score in the index was qualified for the second stage of the research which was based on the extreme case method. The major conclusion from the research is that the commune leader's governance style which allowed him to hold on to power for many terms of office was responsible for generating low governance quality. Furthermore, the low quality of governance was not only the effect of the governance style but also the strategy aimed at remaining in the commune leader office for many terms.

This paper focuses on the understanding of service quality in the context of Vietnamese universities. It proposes an approach for measuring the quality of the higher education service provided by universities in Vietnam. Firstly, an exploratory study was conducted. Then, the set of items which were generated became the subject of a questionnaire that was then administered to 675 students of a Vietnamese university to determine the dimensions of higher education service quality in this context. The obtained results permit us to appropriate a measurement scale which is slightly different from the SERVQUAL scale widely known as the standard for measuring service quality. The results also show that tangible elements, responsiveness and assurance seem to be three specific dimensions of the higher education service of Vietnamese universities.

The recent reprinting of Álvaro de Silva’s 1998 edition of a selection of More’s letters prompts the author to examine the subject of Spanish translations of More, and of de Silva’s general commentary on More’s correspondence and on his relationship to other humanists. The author reflects on aspects of More’s personality as exposed in his letters and uses what he finds as a corrective to several biographical misconceptions. He points out the strengths and weaknesses of de Silva’s work and compares it with that of other translators, particularly Elizabeth Rogers, and notes the particularly Spanish quality of de Silva’s edition.
