Asiakas- ja potilastietojärjestelmät ovat sairaanhoitajien työssä keskeisiä työvälineitä. Artikkelissa selvitettiin, missä määrin eri asiakas- ja potilastietojärjestelmät tukevat sairaanhoitajien työtä eri toimintaympäristöissä. Tavoitteena oli tuottaa tietoa kansallisen tiedonhallinnan strategian täyttymisestä ja sairaanhoitajien käyttäjäkokemuksista palautteeksi tietojärjestelmätoimittajille.

Tiedonkeruu sairaanhoitajien tietojärjestelmäkokemuksista toteutettiin keväällä 2020 kyselynä. Kyselyyn vastasi 3912 sairaanhoitajaa, joista pääosa työskenteli julkisessa sairaalassa, terveyskeskuksessa, sosiaalialalla tai yksityissektorilla. Yleisimmin käytettyjä asiakas- ja potilasjärjestelmiä olivat yleisyysjärjestyksessä Lifecare asiakas- ja potilastietojärjestelmä (Lifecare), Uranus, Pegasos, Apotti (tuotemerkki: Epic), Effica terveydenhuolto (Effica), Mediatri, Esko, DynamicHealth ja DomaCare. Kyselyn väittämistä raportoitiin teemoja, jotka koskevat tietojärjestelmien kykyä tukea vuorovaikutusta (4), hyötyjä (4), käytettävyyttä (2), teknistä toimivuutta (3) sekä paperin ja faksin käyttöä (1), tietojärjestelmille annettavia kouluarvosanoja (1) ja järjestelmätoimittajille suoraan annettavaa palautetta (30). Kysely tehtiin sairaanhoitajille toista kertaa, ja pohdinnassa tarkasteltiin muutoksia vuoteen 2017 nähden.

Tulosten mukaan tietojärjestelmien tuki sairaanhoitajien työlle parantui tai pysyi ennallaan monien muuttujien osalta. Tulokset vaihtelivat asiakas- ja potilastietojärjestelmien tuotemerkkien ja toimintaympäristöjen välillä ja myös samojen tuotemerkkien välillä eri toimintaympäristöissä. Sairaanhoitajat olivat tyytyväisiä etenkin tietojärjestelmien kykyyn tukea yhteistyötä ja tiedonkulkua sairaanhoitajien kesken organisaation sisällä sekä sairaanhoitajien ja lääkärien välillä. He myös kokivat, että tietojärjestelmät tuottavat hyötyjä asiakkaiden ja potilaiden hoitoprosessille. Toisaalta organisaatioiden välisessä tiedonkulussa turvauduttiin edelleen paperiin ja faksiin. Lisäksi vastaajat tunnistivat asiakas- ja potilastietojärjestelmissä enemmän työtä hankaloittavia kuin hyvin toimivia ominaisuuksia. Vaikka tietojärjestelmien kehityssuunta vaikutti positiiviselta, eivät ne kaikilta osin edelleenkään tukeneet sairaanhoitajien työtä riittävällä tasolla ja näin ollen tietojärjestelmien systemaattista seurantaa on syytä jatkaa.

Road traffic modelling based on the hybrid modelling tool AnyLogic
Authors: Benčat Gabriel , Janota Aleš
Published: October 2020

The increasing complexity of modelled systems opens up questions of combining several modelling approaches in order to achieve higher efficiency and the required clarity of the simulations performed. For this reason, in addition to standard application-oriented modelling tools, we can see the growing popularity of the so-called hybrid or multimethod modelling approaches. A typical representative of such a modelling environment is the AnyLogic general-purpose modelling tool. This article describes the authors' experience with this tool in solving a selected problem in the field of modelling transport processes in urban areas. Using the example of the uncontrolled selected intersection, the procedure of creating a model with a more detailed analysis of its selected parts is discussed. The model based on real conditions is elaborated and compared with the model containing the fictitious traffic light control. Comparison is based on measuring the time that vehicles moving in the critical direction spend in the model. Both discussed models are stored in the cloud and may be run and study free.

The article presents a mathematical model assessing the reliability of rail traffic control systems with a mounted Peltier cell. The semiconductor element will be used for operating electronic components that are in the trackside equipment. In the prepared model, Markow processes were used to describe the states occurring between individual components of the RTC System. Simulation tests were mainly based on determining the average time of component failure. The presented results were carried out for 1,000, 2,000 and 3,000 rail vehicle crossings over the railway tracks equipped with RTC Systems. At the very end of the article the conclusions resulting from computer simulations were presented.
HEAVENLY TEARS � EARTHLY LOSS: DIFFERENT WAYS OF COPING WITH LIFE LOSS IN TEARS IN HEAVEN, CIRCUS, AND SINCE I LOST YOU
Authors: Akun Akun
Published: October 2020

This is a qualitative study of three pop songs rooted from the same tragic event of Eric Clapton?s son Conor who fell from the 53rd floor of his spouse?s New York apartment in March 1991. Two songs are from Clapton himself i.e. Tears in Heaven and Circus and one song from his friend Phil Collins entitled Since I Lost You. The goal of this study is to elaborate the attitude of the author through the study of formal aspects of the song such as rhyme, rhythm, tone and picth and also the metaphorical expressions in their wording. This is a library research of the three songs using a comparative technique of elaboration. The study concludes that Phil Collins as a friend who is not directly involved in the tragedy shows his sympathy through a negative and hopeless way of seeing the tragedy. He focuses more on the tragedy directly rather than the impact, psychologial process and lessons learned afterward. Eric Clapton, on the other hand, as the one who directly suffers the impact of the tragedy sees the tragic event from a more positive angle. He tries to somehow show his grief but does not want to be drifted away in this sorrow. He focuses more on the process after the tragedyby remembering the sweet moment before the tragedy (in Circus) and imagine the same sweet thing after the tragedy (in Tears in Heaven) by setting an emotional spin around the good memory and nice after life state of the child with sweet hopes and strengthening consolation
SEEKING REFUGE IN THE PAST. BERET’S FAMILY CHEST IN O.E. RØLVAAG’S GIANTS IN THE EARTH
Authors: MUREȘAN Ioana-Andreea
Published: October 2020

Seeking Refuge in the Past. Beret’s Family Chest in O.E. Rølvaag’s Giants in the Earth. This study explores the importance of homeland treasures for the immigrants longing to belong. Beret Holm, the female protagonist in Giants in the Earth, speaks for the difficulties faced by Norwegian settlers in the Dakota prairie during the 19th century, both in what concerns the land they are about to conquer, but also in what concerns their sense of belonging, as well as the preservation of their identity in the American melting pot. The family chest she had brought from Norway, in which she kept all the treasures, all the memories from the homeland, would become her shelter during a locust plague that ravages the settlement. Torn by remorse for having left her country and parents, Beret seeks refuge from the wrath of God, hiding with her children in the very object that was so dear to her, her sole remembrance of an intangible past. The family chest that she sees as her coffin in a moment of despair would become the altar for the ritual of communion held by a Norwegian Lutheran priest, a ritual which would bring comfort to her troubled soul.
REZUMAT. Căutând adăpost în trecut. Cufărul lui Beret din Uriași pe pământ de Ole Edvart Rølvaag. Studiul de față analizează importanța lucrurilor de preț din țara natală pentru imigranții care tânjesc după apartenență. Beret Holm, protagonista romanului Uriași pe pământ, este exponenta dificultăților întâmpinate de pionierii norvegieni în preeria din Dakota în secolul al XIX-lea, atât în ceea ce privește pământul pe care sunt pe cale să-l cucerească, cât și în privința sentimentului lor de apartenență și păstrarea identității în creuzetul american de culturi. Cufărul familiei, pe care-l adusese din Norvegia și în care își păstra toate lucrurile de preț, toate amintirile din țara natală, va deveni adăpostul ei în timpul unei invazii a lăcustelor care face ravagii în așezământ. Chinuită de remușcări fiindcă și-a părăsit țara și părinții, Beret caută adăpost de mânia lui Dumnezeu și se ascunde împreună cu copiii tocmai în obiectul care-i era atât de drag, singura amintire a unui trecut intangibil. Cufărul familiei care aproape-i devine sicriu într-un moment de disperare va fi altarul în ritualul împărtășaniei ținut de un preot luteran norvegian, ritual care va aduce pacea sufletului ei tulburat.

Published: October 2020

En una época de prevalencia audiovisual, Juan José Millás (Valencia, 1946), que nunca permanece ajeno a los cambios socioculturales, ha variado su percepción y su mirada. En tres de sus obras —Todo son preguntas, El ojo de la cerradura y Sombras sobre sombras— ha recopilado textos que se adscriben al género comentario de fotografía. Millás analiza imágenes de prensa, con lo que demuestra que ha acogido con éxito en su literatura el análisis visual de la realidad como nuevo modo de relación con el universo.

The Periodic Table needs negative orbitals in order to eliminate quantum weirdness: a new quantum chemistry mathematics
Authors: Jeffrey H. Boyd
Published: October 2020

A consensus among quantum experts is that the quantum world is not properly understood. It is a mistake to think we can cure quantum weirdness by tinkering with superficial aspects of quantum mechanics (QM). We propose that nature uses  (–ψ) as its wave function, whereas QM uses (+ψ). We propose therefore that the Periodical Table should be changed to negative orbitals (–ψ). Surprisingly, this change makes almost no difference to chemistry on a practical level. The Born rule takes the absolute square of an amplitude to obtain a probability to test in chemistry lab P=|–ψ|2=|+ψ|2. We propose a new math based on (–ψ) that is the mirror image of quantum mathematics. We call it the Theory of Elementary Waves (TEW). The negative sign is not an electrical charge. It has nothing to do with Coulomb’s law. Valence electrons are unchanged. Ions, covalent bonds, dipoles, metals, hydrogen bonding and the hydrogen 21 cm line are unchanged. The octet rule and rules for drawing dot structures of molecules do not change. Amino acids, sugars and DNA do not change their handedness. We cite abundant experimental evidence showing that TEW is correct and QM is wrong.
Observability of Production of tttt quarks at pp-colliders in new physics models

Published: October 2020

The Standard Model production of four top quarks in the process pp --> tttt at a center-of-mass energy s1/2=13 Tev. The data collected by the ATLAS detector represents an impressive study potential, with an integrated luminosity of around 139 fb-1. In this manuscript, we present the production process of four top quarks at the LHC as well as some new physics models associated with this process. These models are studied in analysis carried. Some preliminary results are presented, in particular those of a new method for estimating background noise due to false leptons developed.
Application of Shannon Entropy in the Construction of a Paraconsistent Model of the Atom
Authors: João Inácio da Silva Filho
Published: October 2020

In this paper, we present a model of the atom that is based on a nonclassical logic called paraconsistent logic (PL), which has the main property of accepting the contradiction in logical interpretations without the conclusions being annulled. The proposed model is constructed with an extension of PL called paraconsistent annotated logic with annotation of two values (PAL2v), which is associated with an interlaced lattice of four vertices. We use the logarithmic function of the Shannon entropy H(s) to construct the paraconsistent equations and thus adopt a probabilistic model for representations in quantum physics. Through analyses of the interlaced lattice, comparative values are obtained for some of the phenomena and effects of quantum mechanics, such as superposition of states, wave functions, and equations that determine the energy levels of the atomic shells of an atom. At the end of this article, we use the hydrogen atom as a basis for the representation of the PAL2v model, where the values of the energy levels in six orbital shells are obtained. As an example, we present a possible method of applying the PAL2v model to the use of Raman spectroscopy signals in the detection of lubricating mineral oil quality.

Published: October 2020

Tuberculosis is an airborne infectious disease that remains a huge global health-related issue nowadays. Despite constant approvals of newly developed drugs, the use of first-line antituberculosis medicines seems reasonable in drug-susceptible Mycobacterium tuberculosis strains. Therapeutic drug monitoring presents a useful technique for the determination of plasma drug concentration to adjust appropriate dose regimes. In tuberculosis treatment, therapeutic drug monitoring is aiding clinicians in selecting an optimal therapeutic level, which is essential for the personalisation of therapy. This review is aimed at clarifying the use of therapeutic drug monitoring of the first-line antituberculosis drugs in routine clinical practice.

Most Pb and Cd neurotoxicity studies investigate exposure to either of the toxic metals alone, while data on co-exposure are scarce. The aim of our study was to fill that gap by investigating acute combined effects of Pb and Cd on redox and essential metal status in the brain of Wistar rats. Animals were randomised in four groups of six to eight rats, which received 15 or 30 mg/kg of Cd, 150 mg/kg of Pb, or 150 mg/kg of Pb + 15 mg/kg of Cd by gavage. The fifth, control, group received distilled water only. Co-treatment with Pb and Cd induced significant increase in malondialdehyde (MDA) and thiobarbituric acid-reactive substances (TBARS) compared to control and groups receiving either metal alone. This is of special importance, as MDA presence in the brain has been implicated in many neurodegenerative disorders. The groups did not significantly differ in Zn, Cu, Mn, and Fe brain levels. Our findings highlight the importance of metal mixture studies. Neurotoxicity assessments of single chemicals do not provide a real insight into exposure to mixtures in real life. Further research should look into interactions between these metals to reveal complex molecular mechanisms of their neurotoxicity.
Capillary bacterial migration on non-nutritive solid surfaces
Authors: Ivanković Tomislav , Hadad Uzi , Kushmaro Ariel , Dekić Svjetlana , Ćevid Josipa , Percela Marko , Hrenović Jasna
Published: October 2020

Here we describe an additional type of bacterial migration in which bacterial cells migrate vertically across a non-nutritive solid surface carried by capillary forces. Unlike standard motility experiments, these were run on a glass slide inserted into a Falcon tube, partly immersed in a nutrient medium and partly exposed to air. Observations revealed that capillary forces initiated upward cell migration when biofilm was formed at the border between liquid and air. The movement was facilitated by the production of extracellular polymeric substances (EPS). This motility differs from earlier described swarming, twitching, gliding, sliding, or surfing, although these types of movements are not excluded. We therefore propose to call it “capillary movement of biofilm”. This phenomenon may be an ecologically important mode of bacterial motility on solid surfaces.

Microservices Centric Architectural Model for Handling Data Stream Oriented Applications
Authors: Philip Milu Mary , Seshadri Amrutha , Vijayakumar B.
Published: October 2020

The present-day software application systems are highly complex with many requirements and variations, which can only be handled by more than one architectural pattern. This paper focuses on a combinational architectural design, with the micro-services at the center and supported by the model view controller and the pipes and filter architectural patterns to realize any data stream-oriented application. The proposed model is very generic and for validation, a prototype GIS application has been considered. The application is designed to extract GIS data from internet sources and process the data using third party processing tools. The overall design follows the micro-services architecture and the processing segment is designed using pipes-and-filters architectural pattern. The user interaction is made possible with the use of the model view controller pattern. The versatility of the application is expressed in its ability to organize any number of given filters in a connected structure that agrees with inter-component dependencies. The model includes different services, which make the application more user-friendly and secure by prompting client for authentication and providing unique storage for every client. This approach is very much useful for building applications with a high degree of flexibility, maintainability and adaptability. A qualitative comparison is made using a set of criteria and their implementation using the different architectural styles.

Authors: Dhingra Shefali , Bansal Poonam
Published: October 2020

Content Based Image Retrieval (CBIR) system is an efficient search engine which has the potentiality of retrieving the images from huge repositories by extracting the visual features. It includes color, texture and shape. Texture is the most eminent feature among all. This investigation focuses upon the classification complications that crop up in case of big datasets. In this, texture techniques are explored with machine learning algorithms in order to increase the retrieval efficiency. We have tested our system on three texture techniques using various classifiers which are Support vector machine, K-Nearest Neighbor (KNN), Naïve Bayes and Decision Tree (DT). Variant evaluation metrics precision, recall, false alarm rate, accuracy etc. are figured out to measure the competence of the designed CBIR system on two benchmark datasets, i.e. Wang and Brodatz. Result shows that with both these datasets the KNN and DT classifier hand over superior results as compared to others.

Published: October 2020

Many diseases are associated with oxidative stress are caused by free radicals. Current research has been directed towards finding naturally occurring antioxidants of plant origin. The aim of the present study was to evaluate the in vitro antioxidant activities of methanolic extract of Lawsonia inermis L. bark (MELIB). The present study was carried out for determination of qualitative, quantitative phytochemical and in vitro antioxidant activity for scavenging of free radical DPPH, superoxide radical scavenging and lipid peroxidation. The bark extract is a rich source of secondary metabolites like flavonoids at a rutin equivalent 73.43±0.26%, polyphenol at a gallic acid equivalent 84.70±0.43%, tannins at a tannic acid equivalent 88.75±0.14% and terpenoids at a linalool equivalent 68.13±0.31. MELIB showed free radicals scavenging capacity by way of the DPPH method (6.93±0.51 to 62.63±0.10% inhibition), the superoxide radical scavenging method (1.82±0.41 to 57.11±0.18% inhibition) and the ferric chloride induced lipid peroxidation method (9.87±0.33 to 80.32±0.82% inhibition). The results obtained in the present study indicate that MELIB can be a potential source of natural antioxidants due to the presence of flavonoids, polyphenols, tannins and terpenoids.
The effect of a selective estrogen receptor modulator – raloxifene – on the levels of tryptophan and kynurenic acid in the livers of rats as studied via RP-HPLC-FL

Published: October 2020

The levels of tryptophan (TRP) and its main metabolite kynurenic acid (KYNA) were measured in rat livers treated with raloxifene – a selective estrogen receptor modulator. The research was conducted by applying high-performance liquid chromatography on a 5 μm Zorbax Eclipse XDB-C18 column. Selective fluorescence detection (FL) was performed at an excitation of 219 nm and emission of 360 nm for TRP and KYNA. The assays showed good linearity (R2 >0.95) within the tested ranges of 0.045-0.20 µg mL−1, 0.025-0.32 µg mL−1, respectively, for KYNA and TRP. The limits of the detection were found to be 0.1480 ng mL−1 for KYNA and 0.0332 ng mL-1 for TRP. The deproteinization of the liver homogenate samples was accomplished by 80% methanol addition combined with boiling precipitation. The average recovery values were between 94.84% and 99.54% with RSDs no more than 5.5%. The work revealed that raloxifene decreased the mean value of tryptophan, as compared with the control group, while simultaneously leaving kynurenic acid at the same level. For the first time the research suggests that, in the case of raloxifene therapy, tryptophan is not metabolized via the kynurenine pathway.

Published: October 2020

Asian green mussel is commercially farmed in tidal waters in several enclosed bays in Sabah, Malaysia. In this study, two areas on the west coast of Sabah – Ambong Bay and Marudu Bay – were selected for the monitoring of the growth and mortality rates of green mussels farmed in suspension raft. Both growth and survival rates were then correlated with physicochemical parameters (dissolved oxygen, pH, salinity, temperature, water transparency, chlorophyll-a), nutrients (phosphate (PO4
3-), ammonia (NH3-N), nitrate (NO3-N) and nitrite (NO2-N) and condition index of mussel from each study site, as well as between the study sites. The twelve-month growth study (September 2017 to August 2018) was started with a total of 180 mussel specimens (90 at each site). The initial size (mean) of the mussel seed used was 47.7 ± 3.5 mm and 51.1 ± 3.9 mm for Marudu Bay and Ambong Bay, respectively. Mussels in Marudu Bay attained mean size of 73.47 ± 11.05 mm (SGR 0.17% ± 0.22) compared to 64.05 ± 7.44 mm (SGR 0.11% ± 0.22) for Ambong Bay at the end of the experiment. The cumulative mortality rates were 9.2% ± 4.9 and 55.5% ± 30.0 for Marudu Bay and Ambong Bay, respectively. The Pearson correlation indicated a significant positive relationship between mortality and water transparency (r = 0.684, p<0.01). There was a significant negative relationship between ammonia in seawater and mussel mortality (r = -0.561, p<0.01), as well as significant negative relationships between nitrate and growth (r = -0.480, p<0.05) and mortality (r = -0.460, p<0.05), as indicated by Spearman’s Rank-order Correlation analysis. Overall, the growth performance of green mussels farmed in Marudu Bay was better than in Ambong Bay, however, the mortality of mussels in Ambong Bay was higher.

Background: X-linked adrenoleukodystrophy (X-ALD) is an inherited metabolic disease which causes demyelination of the white matter of the brain. The symptoms include mental impairment, progressive paresis, impaired motor coordination, and epileptic seizures. Diagnosis is established mainly by genetic testing. Currently, the recommended treatment is haematopoietic stem cell transplantation (HSCT).

Goal: The aim of the study was to present the case of a patient suffering from X-ALD, who developed symptoms of bipolar disorder in the initial phase of the disease prior to the onset of characteristic neurological symptoms.

Case presentation: In 2015, a 33-year-old patient was admitted to a psychiatric department due to aggressive behaviour he showed towards his wife and other family members. He had been treated for a depressive episode in 2005, and for a manic episode without psychotic symptoms earlier in 2015. During the successive psychiatric hospitalizations, in addition to psychopathological symptoms, the patient had been observed to have neurological symptoms, which included progressive paraparesis and ataxia. In 2018, based on imaging and genetic tests, the patient was diagnosed with X-ALD. The patient’s condition gradually deteriorated; with time, he was unable to move on his own. During a hospital stay in 2019, he was transferred to an internal medicine department due to a progressive urinary tract infection, which, however, could not be controlled, and the patient died.

Conclusions:

1. X-ALD is a rare metabolic illness. In the early stages of the disease, various psychopathological symptoms, including affective disorders, are observed.

2. Early initiation of adequate treatment increases the chances of extending the patient’s life.

3. In the present case, the patient did not die due to the underlying disease, but due to causes typical of bed-bound patients, i.e. complications of progressing infection.
An Assessment of Sustainability of Rural Areas of Upper Beas Valley, Himachal Pradesh, India
Authors: Jolli Virat
Published: October 2020

Subject and purpose of work: The study aims to assess the sustainability of rural areas of Western Himalayas during the year 2019.

Materials and methods: A questionnaire-based survey was conducted in upper Beas Valley of Himachal Pradesh. A total of 101 individuals were interviewed and the questionnaire was filled by the surveyor.

Results: Survey showed that high level of unemployment prevailed in the region with minimal monthly income. However, they engaged in agriculture and allied activities along with collection of non-timber forest products (NTFPs) to supplement their incomes. The proximity to protected areas led to frequent encounter with wildlife and such encounters increased after the commencement of Hydro Power Projects. Respondents believed that construction HPPs and expansion road network in the region has increased the occurrence of landslides; and many of them had lost their cultivated land due to landslides.

Conclusions: The study showed rural areas of upper Beas Valley were moderately unsustainable.
Savings and Migration Capital of Households: World Experience and Domestic Realities
Authors: Kluchnyk Liliya , Davymuka Stepan
Published: October 2020

Subject and purpose of work: The subject of the paper is the formation of household savings in Ukraine and their sources of aggregate household incomes, with particular attention to the Ukrainian labor migration. It is an important source of foreign exchange earnings in the form of remittances, which help improve the welfare of population and ensure economic growth in the country.

The purpose of the paper is to research and determine major trends of the development of households’ financial resources, to examine the foreign experience of forming and use of residents’ savings and to determine the ways it can be applied in Ukraine, and to analyze the main trends of state policy in the regulation of labor migrants’ remittances.

Materials and methods: The author of this paper analyzed the literature on the subject and performed desk research using data from reports and studies published by EU statistics (Euro stat Statistics) and GUS (Statistics Poland), statistical yearbooks of Europe; WDR reports (Global Financial Development Report 2019/2020) and NBU (Official website of the National Bank of Ukraine).

Results: The author’s research has shown that the process of saving is quite popular for European people is quite popular. Accordingly, in 2019, the residents of Poland, Hungary and Romania were the most frugal – 82%, 84% and 85%. Further attitudes towards savings are the following: Turks (77%), Ukrainians (76%), Croats (75%), Serbs (72%), Germans (73%), while savings are slightly less important for Austrians (70%), Slovaks (67%), Czechs (66%), and Montenegrins (59%). This savings situation has clearly demonstrated the power of effective household decisions for overall political and economic activity in Europe. Finally, the migration capital of Ukraine has a “shadow character” due to, first of all, the desire to minimize the costs of transferring funds home through official channels, as well as distrust of the banking sector in Ukraine.

Conclusions: To increase the efficiency of the formation and use of household savings in Ukraine, it is necessary to increase the interest of citizens in savings by partially or completely exempting from taxation the income directed to accumulation and create the conditions necessary for the implementation of new banking, insurance, and other types of financial services.

Published: October 2020

The process of decentralization of power and governance, which takes place in Ukraine through the voluntary unification of territorial communities, has laid the foundations for reforming the administrative territorial structure and territorial organization of power. Taking into account the state making nature of these transformations in the context of Ukraine’s European integration efforts, the article substantiates theoretical and applied fundamentals of branding of cultural tourism objects of the united territorial communities (UTC), reveals his role in constructing local identity of these social and spatial formations. The methodology of the study covers three main thematic blocks: legal and political foundations of the creation of a UTC; features of UTC branding; conceptualization and classification of brand projects of cultural tourism objects of the UTC. The factors that inhibit the branding process of cultural tourism objects of these communities were identified, conclusions were drawn, and perspective directions for further scientific exploration were outlined.

Deep learning methods, used in machine vision challenges, often face the problem of the amount and quality of data. To address this issue, we investigate the transfer learning method. In this study, we briefly describe the idea and introduce two main strategies of transfer learning. We also present the widely-used neural network models, that in recent years performed best in ImageNet classification challenges. Furthermore, we shortly describe three different experiments from computer vision field, that confirm the developed algorithms ability to classify images with overall accuracy 87.2-95%. Achieved numbers are state-of-the-art results in melanoma thickness prediction, anomaly detection and Clostridium di cile cytotoxicity classification problems.
A percentile-based estimator for the log-logistic function: Application to forestry
Authors: Ogana Friday Nwabueze
Published: October 2020

Developing a simplified estimation method without compromising the performance of the distribution is germane to forest modelling. Few estimation methods exist for the Log-Logistic distribution and are relatively complex. A simplified estimator for the Log-Logistic parameters will increase its application in diameter distribution yield systems. Therefore, in this study, a percentile-based estimator was applied for the Log-Logistic distribution. The Kolmogorov-Smirnov, Anderson-Darling and Cramer-von Mises statistics were used to evaluate the method in two natural forest stands and two monospecific plantations of Gmelina arborea Roxb. and Tectona grandis Linn. f. in Nigeria. The parameter recovery model (PRM) and parameter prediction model (PPM) were used to predict the diameter distributions of independent stands of G. arborea and T. grandis. The results showed that the percentile estimator did not compromise the quality of fits of the Log-Logistic function across the four forest stands and are comparable to the maximum likelihood estimator. The 25th and 75th, and 40th and 80th were the best sample percentiles for the estimator. The predicted diameter distributions of G. arborea and T. grandis stands from the PRM and PPM were reasonable and compare well with the observed distribution. Thus, either of the models can be incorporated into the growth and yield system of forest stand management.

The interest in the experience of legislative solutions to problems connected with the design and development of legal institutions in environmental protection in foreign countries, at first glance, is not directly related to the study of the laws of functioning and development of this legal institution. The relevance of the study is determined by the fact that such an interest appears as rather justified and even logical, if one is to proceed, firstly, from general ideas about the development of land legislation in the context of globalisation, and secondly, if one is to consider the desire of countries to more widely implement global and European standards of environmental policies and rights and approaches to environmental protection in general. The purpose of this article is determined by the identification the main problems of land protection legislation in the field of and form on their basis the effective system of environmental regulation, combining administrative and legislative instruments with economic, regulatory and market mechanisms. Analysis of international legal acts is used as the leading research method. It was determined that the positive experience in foreign countries related to the legal regulation of relations in legal protection of the environment allows transferring the theoretical ideas about the legal structures existing in other countries to the practical plane, which, in turn, allow to optimally regulate the appropriate circle of public relations, taking into consideration the relevant historical traditions, the internal structure of national legislation, the features of the development of environmental legislation of the respective country. The concept of protecting land from pollution by hazardous substances and ways of improving and adapting legislation in the field of waste management were proposed. The practical significance of the study is determined by the need to integrate the land legislation industry into national environmental legislation.

Published: October 2020

Background and Objective

This study was aimed to elucidate the molecular mechanism of Momordica charantia (MCh), along with a standard drug prednisolone, in a rat model of colitis induced by trinitrobenzene sulfonic acid (TNBS).

Methods

After the induction of the experimental colitis, the animals were treated with MCh (4 g/kg/day) for 14 consecutive days by intragastric gavage. The colonic tissue expression levels of C-C motif chemokine ligand 17 (CCL-17), interleukin (IL)-1β, IL-6, IL-23, interferon-γ (IFN-γ), nuclear factor kappa B (NF-kB), and tumor necrosis factor-α (TNF-α), were determined at both mRNA and protein levels to estimate the effect of MCh. Besides, colonic specimens were analyzed histopathologically after staining with hematoxylin and eosin.

Results

The body weights from TNBS-instigated colitis rats were found to be significantly lower than untreated animals. Also, the IFN-γ, IL-1β, IL-6, Il-23, TNF-α, CCL-17, and NF-kB mRNA and protein levels were increased significantly from 1.86-4.91-fold and 1.46-5.50-fold, respectively, in the TNBS-instigated colitis group as compared to the control. Both the MCh and prednisolone treatment significantly reduced the bodyweight loss. It also restored the induced colonic tissue levels of IL-1β, IL-6, IFN-γ, and TNF-α to normal levels seen in untreated animals. These results were also supported with the histochemical staining of the colonic tissues from both control and treated animals.

Conclusion

The presented data strongly suggests that MCh has the anti-inflammatory effect that might be modulated through vitamin D metabolism. It is the right candidate for the treatment of UC as an alternative and complementary therapeutics.
