The purpose of the article. Studying deformation characteristics of protective structures under the influence of external loads used to maintain lateral rocks in the coal massif behind the production face. Methods. To achieve this goal, laboratory studies of the deformation characteristics of security structures under uniaxial compression were performed. Results. As a result of the research it has been established that at uniaxial compression of wooden protective constructions in the form of rolling fires from sleepers or bushes from risers, change of their rigidity is caused both by differences in properties of wood at action of external force along or across fibres, and design features. In cases where a constant compressive force is applied to the experimental sample across the fibres (rolling fires from sleepers), the change in stiffness is quadratic and reaches minimum values when the deformation of the model by 30-35%, and with a further increase in deformation to 50% stiffness increases. This indicates an increase in the resistance of rolling fires to external loads after their compression, without losing the strength of the structure. Under the action of compressive force along the fibres (bushes of risers), the stiffness of the experimental samples increases until the moment of destruction, when there is a loss of strength of the structure. The change in the stiffness of embedded arrays of crushed rock, if possible, their lateral expansion occurs due to the compaction of embedded material, i.e. recomposition of particles of crushed rock of different fractions in the total volume. Novelty. The nature of the deformation of security structures considered as prefabricated structures can be described by the change in the specific potential deformation energy spent on changing the shape and/or volume of the protective structures. Practical meaning. To ensure the stability of the side rocks in the coal massif containing the workings, it is necessary to focus on the use of flexible protection structures located above the retractable roadway.

Purpose. Identification of the features and the properties of segnetoelastics in rocks. Research Methods. Laboratory experiments on the deformation of rocks in a volume field of compressive stresses, macro- and microscopic studies of the deformations and the orientations of an optical indicatrix, analysis of the data obtained. Research results. As a result of microscopic and optical studies of rocks in thin sections on a polarizing microscope, tests of rocks under the conditions of unequal triaxial compression, analysis of the results obtained, it was found that the rock-forming minerals of the sedimentary sequence at a normal temperature and in the absence of an external load have a domain structure. Under the conditions of a triaxial unequal component compression, the volumetric deformations at the micro and macro levels do not exceed hundredths, while the relative micro deformations fully correspond to the dilatancy volume at the macro level. Shear rotational deformations reach 15–20%, their resonant increment increases several times over three periods before the destruction. During the loading, the direction of the rotation is changed 3-4 or more times, an optical indicatrix changes the direction. All deformations are alternating in sign and, until resonance, the amplitude of their increment does not exceed 0.5%. During the loading, the deformation, elastic, optical, electromagnetic, and other parameters are changed abruptly (structural-phase transitions of the second, and upon the destruction, of the first and third kind). The interconnection between the load and the deformations is nonlinear, a number of characteristic deformations are distinguished at which these jumps occur. All said indicate that rocks are classical distortion segnetoelastics. The following parameters can be taken as parameters of a segnoelastic transition: the value or increase in the value of relative deformation; an elastic modules varying within ± ∞; the sign and the magnitude of the increment of the Lode angle for the deformations; the angle of rotation of the optical indicatrix, the presence of structural-phase transitions in the minerals. Scientific novelty. It has been shown for the first time that all five signs and traits of segnetoelastics are present in sedimentary rocks. Practical significance. The possibility for isolating of segnetoelastics without laborious microscopic and electromagnetic studies.

Published: January 2021

Enamel matrix derivative (EMD) can enhance proliferation and migration of different oral cell lines,
including malignant oral carcinoma cells, in vitro and in vivo. The composition of EMD is not known, but
part of the effects have been postulated to be caused by transforming growth factor-beta-1 (TGF-beta 1).
This study aimed to compare target genes of EMD and TGF-beta 1 on highly malignant oral carcinoma
HSC-3 cells. Microarrays were used to examine differentially expressed genes in HSC-3 cells after 6h and
24h incubations with EMD (200 µg/ml) or TGF-beta 1 (10 ng/ml). Gene Ontology (GO) enrichment analysis
of the regulated genes was also conducted. After 6h and 24h of EMD treatments 42 and 12 genes,
respectively, were statistically significantly (P<0.05) up- or down-regulated. However, as many as 393 and
346 genes were statistically significantly (P<0.05) up- or down-regulated by TGF-beta 1. Among the most
up-regulated genes by both of the study reagents were MMP-9 and -10. The expression of MMP-10 by
EMD treated carcinoma cells was also verified in protein level. In conclusion, TGF-beta 1 regulates more
and mostly different genes compared with EMD, but both regulate the expression of matrix
metalloproteinase genes in oral carcinoma cells.

Published: January 2021

Pituitary apoplexy is a rare endocrine emergency that can occur due to bleeding or ischemia in the pituitary
gland. Its incidence can vary between 0.6% and 16.8% in the general population (2-7% in pituitary
adenomas). We herein report an unusual case of a 50-year-old female patient who presented to the
emergency with complaints of left hemicranial headache, cervicalgia, shoulder pain and dizziness for 1 year
worsened in the last three days. Her prolactin levels were high, and the first imaging exam suggested a silent
apoplexy, since the clinical picture of the patient did not indicate such condition. In the second one, the
patient presented a typical picture of apoplexy, including intense headache and nausea. Her temporal
evolution suggested a macroprolactinoma with hemorrhagic degeneration or apoplexy. As she did not
present signs of indication for transsphenoidal emergency surgery, conservative treatment was chosen. In
this case, due to history of repeated apoplexy, nausea and intense headache, it is important to keep close
monitoring for an eventual urgent surgical intervention in case of new bleeding, visual alterations and/or
reduced level of consciousness, since these are indicative signs for transsphenoidal emergency surgery.

Abstract. Water intake is an essential element of the water supply complex, normal operation of which depends on the quality of the water delivered to the consumer. Therefore, the water supply system should be effectively protected from various contaminants from the source, ice slurries, and juvenile fish. The authors analyze the operation of existing coarse screen devices in channel water intakes; identify their main disadvantages, such as: mechanical jamming (clogging) of the screen holes with debris, leading to its failure and the need to replace, as well as the laborious cleaning and the high cost of screen materials. The article notes that during operation there is an increase in the pressure drop affecting the screen due to the accumulation of a large amount of contaminants on its surface, which could lead to a throughput and a significant amount of pollution. To improve the quality of filtered water and operating conditions, the authors proposed to provide porous pipes installation instead of flat removable screens in the receiving section of the intake well. The material for their manufacture is a polymer concrete, based on crushed granite stones or gravel and a polymer binder – epoxy resin. The article shows the scheme of intake well pipes installation, describes the principle of the proposed design, shows a graph obtained as a result of hydraulic calculation. This design has a number of advantages over flat screens: automation of flushing, less clogging, greater throughput, lack of biofouling, high strength characteristics, low hydraulic resistance and durability. A porous polymer concrete-based structure, which is a pipe system that increases the reliability of water intakes, improves the quality of the water taken from the source and the conditions of operation, has been proposed. The method of hydraulic calculation of porous pipes makes it possible to optimize their design parameters, to determine the diameter and pressure loss in them, which is very important when designing water intakes. The aim of further research is to study the dynamics and degree of porous devices clogging by suspension at different concentrations in natural water.

Abstract. The article explores the issues of the emergence and development of historical parks in Ukraine. There are four periods of formation and development of historical parks in Ukraine: the first ‒ from the times of Kievan Rus to the middle of the 17th century (the origin of park building), the second ‒ from the middle of the 17th century before the revolution of 1917 (construction of mainly private palaces and park ensembles), the third ‒ from 1918 to 1991 (soviet period), the fourth ‒ from 1991 to the present (the period of independence of Ukraine). The definition of the concept «historical park» is given. The park is a work of art. A unique situation in human practice: to create a living and perfect work of art at the same time. Gardens and parks provide this opportunity. The park is history. The historical park preserves and broadcasts this history to us ‒ it is an object of cultural heritage, our common heritage. Sometimes the park is also a museum-reserve and bears the function of preserving heritage. Historical gardens and parks often acquire the status of monuments. Monuments of landscape gardening art are historical and cultural monuments that organically include plants, landscape features (hills, water sources and waterfalls, stream or river valleys, stones, rocks, distant landscape perspectives, sometimes wetlands), architectural structures, sculptures, flower beds, etc. Historical parks of cities include palaces and manor complexes, botanical gardens, city parks and memorial parks, as well as parks-monuments. In total, there are 88 historical parks-monuments of landscape gardening art of national and 426 local significances in Ukraine. Parks-monuments of landscape gardening art of local importance include: parks of culture and recreation, arboretums, woodlands used as recreation parks, and other objects. In particular, in the Odessa region there are 22 parks-monuments, in the city of Odessa ‒ 5 parks-monuments of gardening art (T. Shevchenko Park, Dyukovsky Garden, City Garden, Victory Arboretum, Park named after Savitsky). The article highlights the main problems in the restoration work of historical parks and solutions. The history of the emergence and development of parks in Ukraine is analyzed. It was concluded that the historical parks are multifaceted and interesting not only for architectural ensembles, but also for their biocenosis.

Published: January 2021

Abstract. The results of scant attention to questions of artistic cultural decay and esthetic expressiveness are critical condition and often lack of artistic emotional and figurative perception of urban architectural environment and most of public and housing objects in Ukraine. One of the ways of dealing with this problem is implementation of specified means and techniques of artistic design. Many scientists research color and form impact on the urban architectural environment, however the attention is paid to the solution of general theoretical questions often ignoring artistic factor. That's why it is important to systematize information about means of formation of emotional and figurative perception of urban architectural environment accounting artistic factor and determine artistic techniques for form and color implementation to urban architectural environment. The aim and tasks of work are to systematize information about means for emotional and figurative perception of urban architectural environment using artistic factor, determine techniques for implementing main tools of artistic design to architectural and urban environment. Therefore, analysis and systematization of scientific research results, literary and informational sources revealed that such tools as form and color have the most significant influence on the formation of emotional and figurative perception of urban architectural environment within artistic design. As the result of the comparative analysis of existing knowledge six artistic techniques of implementing form and color to architectural and urban environment are presented. Among them are technique of polar contrast utilization, technique of highlighting, technique of rhythm, technique of dynamism or transparency, technique of expressiveness and technique of form and color subjectivity. Above mentioned techniques for implementing form and color to architectural and urban environment are basic for the development of the author's own language of self-realization by architect-artist. Using these techniques both together and separately, their successful combination can create an architectural and urban environment with a unique atmosphere, which is in development and changes constantly, dictates its own rules of perception, elicit an individual emotional response from every visitor.

Student Accountability for Objective Evaluations of Faculty
Authors: Garay Julio
Published: January 2021

ABSTRACT Student Evaluation of Faculty (SEF) is an important component of the US educational system and an indispensable tool to keep track of the faculty’s role to make the institution’s academic practice more engaging, objective and effective. SEF also allows institutions to assess faculty performance, future career stability, advancement and promotion. Unfortunately, SEFs generally exempt students from any responsibility in their own academic outcome. The article presents an analysis of a study based on a modified version of the current SEF form utilised by the Bronx Community College. This modified form includes questions about a student’s responsibilities, to measure their accountability making the evaluation more objective using a descriptive research design method. Results confirmed that students must play an active part in the process by assuming their own responsibilities of regularly and timely attending class, increasing study time, utilising the resources of tutoring, faculty office hours, and extended recitation to improve their own outcome and produce a valid faculty evaluation.

Our objective was to systematically review and synthesize treatment responses to conservative management of non-invasive prostatic urothelial carcinoma using intravesical therapy.

METHODS:

A systematic literature search using MEDLINE, EMBASE, Cochrane Library, SCOPUS, and Web of Science databases from inception to November 2019 was performed. Risk of bias assessment was performed using the Newcastle-Ottawa scale for non-randomised studies. Pooled estimates of complete response in the bladder and prostate and prostate only were performed using a random effects model. Pre-specified subgroup analyses were generated to assess differences in complete responses for: BCG therapy vs other agents, ductal vs mucosal involvement, CIS vs papillary tumors and TURP vs no TURP.

RESULTS:

Nine studies including 175 patients were identified for inclusion in the systematic review and meta-analysis. All were retrospective case series and most evaluated response to BCG therapy. The pooled global complete response rate for intravesical therapy was 60%(95%CI: 0.48, 0.72), and for prostate 88%(95%CI: 0.81, 0.96). Pre-specified analyses did not demonstrate statistically significant differences between subgroups of interest.

CONCLUSIONS:

Management of non-invasive prostatic urothelial carcinoma using intravesical therapy yields satisfactory results. Caution should be taken in treating patients with papillary tumors and ductal involvement, as data for these populations is limited. TURP may not improve efficacy, but is required for staging. Current recommendations are based on low quality evidence, and further research is warranted.

BACKGROUND: Illness perceptions predict chronic low back pain (CLBP) disability. This study cross-culturally adapted and validated the Igbo Brief Illness Perceptions Questionnaire (Igbo-BIPQ) in people with CLBP in rural/urban Nigeria. METHODS: A cross-cultural adaptation and validation of the Igbo-BIPQ was undertaken. The BIPQ was forward/back-translated by clinical/non-clinical translators. An expert review committee appraised the translations. The questionnaire was pre-tested on twelve rural Nigerian dwellers with CLBP. Internal consistency using Cronbach’s alpha; test-retest reliability using intra-class correlation coefficient and Bland-Altman plot; and minimal detectable change were investigated amongst 50 people with CLBP in rural and urban Nigeria. Construct validity was determined by correlating the Igbo-BIPQ score with those of eleven-point box scale and Igbo Roland Morris Disability Questionnaire (Igbo-RMDQ) using Pearson’s correlation analyses in 200 adults with CLBP in rural Nigeria. Ceiling and floor effects were investigated in both samples. RESULTS: Good face/content validity, internal consistency (α= 0.76) and intraclass correlation coefficient (ICC = 0.78); standard error of measurement and minimal detectable change of 5.44 and 15.08 respectively; moderate correlations with pain intensity and self-reported disability (r⩾ 0.4); no ceiling/floor effects were observed for Igbo-BIPQ. CONCLUSION: This study provides evidence of some aspects of validity and reliability of the Igbo-BIPQ.
Adversarial training for few-shot text classification

In recent years, Deep Learning methods have become very popular in classification tasks for Natural Language Processing (NLP); this is mainly due to their ability to reach high performances by relying on very simple input representations, i.e., raw tokens. One of the drawbacks of deep architectures is the large amount of annotated data required for an effective training. Usually, in Machine Learning this problem is mitigated by the usage of semi-supervised methods or, more recently, by using Transfer Learning, in the context of deep architectures. One recent promising method to enable semi-supervised learning in deep architectures has been formalized within Semi-Supervised Generative Adversarial Networks (SS-GANs) in the context of Computer Vision. In this paper, we adopt the SS-GAN framework to enable semi-supervised learning in the context of NLP. We demonstrate how an SS-GAN can boost the performances of simple architectures when operating in expressive low-dimensional embeddings; these are derived by combining the unsupervised approximation of linguistic Reproducing Kernel Hilbert Spaces and the so-called Universal Sentence Encoders. We experimentally evaluate the proposed approach over a semantic classification task, i.e., Question Classification, by considering different sizes of training material and different numbers of target classes. By applying such adversarial schema to a simple Multi-Layer Perceptron, a classifier trained over a subset derived from 1% of the original training material achieves 92% of accuracy. Moreover, when considering a complex classification schema, e.g., involving 50 classes, the proposed method outperforms state-of-the-art alternatives such as BERT.

AI techniques and systems are pervasive to the media and entertainment industry, with application ranging from chatbots and characters to games and virtual environments. A common feature characterising these applications is given by the intent to introduce a narrative element in the user experience, often conveyed through some type of performance. In this paper, we analyse the contribution of AI techniques in the design and realization of a dramatic performance, an interactive system participated by human performers and audiences through some type of enactment. Drawing on real applications developed for innovative performances, we propose an architectural model that forms the technical platform of the system, and discuss how it can be deployed using Artificial Intelligence techniques with reference to real, experimental applications created in the last two decades.

Because of their roles as potential risk factors, we evaluated whether obstructive sleep apnea (OSA) severity interacts with interleukin-6 (IL-6) in predicting incident dementia of the Alzheimer’s type (DAT). In 269 dementia-free participants, IL-6 and the apnea-hypopnea index (AHI) were measured at baseline and incident DAT was surveilled for up to 22.8 years. Cox models revealed a significant interaction: In the lowest IL-6 quartile only, a higher AHI was associated with an elevated risk of DAT. The association between OSA severity and incident DAT might be especially apparent in the absence of inflammation or absence of potential benefits from IL-6.
The Fragility of Temporal Memory in Alzheimer’s Disease
Authors: Park Jin-Hyuck , Lee Sang Ah
Published: January 2021

Background:

Although episodic memory impairment is one of the hallmarks of Alzheimer’s disease (AD), the relative decline in the components of episodic memory ( What, Where, and When) and the effects of cognitive training on each of them are still unknown.

Objective:

We aimed to independently assess the impairment in each component of episodic memory in early to moderate AD and address whether it can be enhanced through active, spatiotemporal episodic training.

Methods:

A non-verbal scene-based episodic memory task was developed to assess the ability to remember What, Where, and When information. Experiment 1 tested whether this task can differentiate AD subjects (N = 16) from healthy controls (N = 16). In Experiment 2, 13 AD subjects underwent 16 training sessions, followed by a re-administration of the scene-based memory task. Experiment 3 tested 42 healthy older adults and 51 younger adults on the same task to investigate the effects of normal aging.

Results:

Of the three components, When memory had the highest predictive power in distinguishing AD from normal aging. Following training of AD subjects, only Where memory improved. Only What memory revealed a significant decline in healthy subjects from 65–85 years of age.

Conclusion:

These findings shed new light on the importance of the temporal component of episodic memory as a behavioral marker of AD. The selective improvement of spatial but not temporal memory through training further demonstrates the fragility of temporal memory even in early AD. Neuroscientific research is needed to distinguish whether the Where component was enhanced by improvements in hippocampal spatial representation or by other compensatory mechanisms.

PEMIKIRAN MUHAMMAD NATSIR TENTANG AGAMA DAN NEGARA
Authors: Badri Ainul

Natsir's view of the relationship between Islam and the state is that religion is not merely a ritual of worship in everyday terms such as prayer or fasting, but religion includes all principles, boundaries in muamalah and social relations. Therefore, in order to ensure that these rules and standards can apply and run as they should, it is necessary and not necessary, there must be strength in social life in the form of power in the state, as warned by the Prophet Muhammad to Muslims that Allah is Allah. holder of the ruling power. It seems that Natsir wants to emphasize that Islam and the state are integrally related, even symbiotic, that is, they are reciprocally related and need each other. In this case, religion needs a state, because with religion and the state it can develop in the field of ethics and morals. This is because in Natsir's understanding that Islam is a complete teaching. Islamic teachings do not contain other aspects such as the field of law regarding statehood, so the establishment of a state is a necessity as argued by H.A.R. Gibb, For Natsir Islam is not just a religion, but also a complete civilization. For that in Islam it is irrelevant to separate Religion from the State because universal Islamic values cannot be separated from the idea of forming a state.
