Authors: Girard Laura , Ringon Constance , Leger-Smith Anaïs
Published: December 2022

Cet article se propose de questionner la place de l’histoire dans le cadre du projet de recherche interdisciplinaire MorpobioT. À travers un corpus de cinq quartiers toulousains aux origines diverses (faubourg, cité Castor, grand ensemble, pavillonnaire et écoquartier), il propose une lecture de l’étude en cours afin de faire ressortir les apports spécifiques de l’histoire dans une recherche qui s’interroge sur la capacité de différents tissus urbains à accueillir et à maintenir une biodiversité en milieu urbain. Les outils de l’historien architecte sont mis en regard de ceux qui sont spécifiques à d’autres disciplines. Il s’agit ici de s’intéresser aux apports de l’histoire à une recherche ancrée dans des questions actuelles : la place du vivant dans les quartiers urbains.
The Impact of the Devaluation Management of the National Currency Against the US Dollar on the Rights of Contractors in Lebanese Law
Authors: Alsamara Tareck , Dbouk Hussein Ali , Farouk Ghazi
Published: December 2022

The article investigates the impact of national currency devaluation management against the US dollar relative to contractor rights. It demonstrates the source of the problem imposed on Lebanon by banking conditions and policies and provides legal solutions to a problem that many contractors still face. This includes an examination of the judicial approach used by Lebanon's judicial bodies to solve legal issues arising from the devaluation of the national currency. According to the article, practice in Lebanon has revealed institutional confusion in determining the value of the national currency in relation to the dollar. To address the issue of assigning the value of the national flag to the dollar, a unified legal system must be established.

Introduction: Bladder cancer grading is fraught with ambiguity. We aimed to conduct a meta-analysis of grading of pT1 urothelial cancers and assess histopathology and outcomes in a Sri Lankan pT1 bladder cancer cohort.
Patients and Method: A meta-analysis of grading of pT1 urothelial cancers was conducted as per PRISMA guidelines. A second metaanalysis of the proportion of pTa/NMIBC at disease presentation was conducted to assess impact of delayed presentation on grading. Analysis was supplemented with data from a cohort of Sri Lankan patients.
Results: In the meta-analysis, the overall pooled pT1 HG prevalence was 75.3% [95% CI:68.3%-81.7%]. The pT1 HG prevalence was significantly higher (p=4.916878e-11) among the European, Japanese and Taiwanese studies at 90.1% [95% CI: 85.3%-94.0%] compared to the rest of the countries at 56.1% [95% CI:46.5%-65.4%]. The overall pooled pTa/NMIBC prevalence was 44.2% [95% CI:36.4%-52.1%]. The pTa/NMIBC percentage among Europe, China and Taiwan was 66.9%[95% CI:62.4%-71.2%] and it was 37.6% [95% CI:29.0%-46.6%] in Turkey and other Asian countries indicating a significant difference(P=1.08e-08). In the Sri Lankan cohort of 66 enrolled patients, 31(47%) had pT1, of which 61% were low-grade (LG). The 5-year progressionfree survival (PFS) of pT1 was 60.9%. In LG it was 85.7% and 22.2% in high-grade (HG) (P = 0.0006).
Conclusion: There is a global variation of percentages of pT1 LG versus HG disease in bladder cancer specimens at presentation which could be attributed to delay in treatment with stage migration, ethnic variations in tumour biology, and interobserver variability in assigning a grade of tumour, and needs further study.
Motion sickness susceptibility and visually induced motion sickness as diagnostic signs in Parkinson’s disease
Authors: Petel Arthur , Jacob Deborah , Aubonnet Romain , Frismand Solène , Petersen Hannes , Gargiulo Paolo , Perrin Philippe
Published: December 2022

Postural instability and loss of vestibular and somatosensory acuity can be part of the signs encountered in Parkinson’s Disease (PD). Visual dependency is described in PD. These modifications of sensory input hierarchy are predictors of motion sickness (MS). The aim of this study was to assess MS susceptibility and effects of real induced MS in posture. 63 PD patients, whose medication levels (levodopa) reflected the pathology were evaluated, and 27 healthy controls, filled a MS questionnaire; 9 PD patients and 43 healthy controls were assessed by posturography using virtual reality. Drug amount predicted visual MS (p=0.01), but not real induced MS susceptibility. PD patients did not experience postural instability in virtual reality, contrary to healthy controls. Since PD patients do not seem to feel vestibular stimulated MS, they may not rely on vestibular and somatosensory inputs during the stimulation. However, they feel visually induced MS more with increased levodopa drug effect. Levodopa amount can increase visual dependency. The strongest MS predictors must be studied in PD to better understand the effect of visual stimulation and its absence in vestibular stimulation.
Monitoring daily symptoms and (self-reported) exacerbations in patients with bronchiectasis: a prospective study
Authors: Campos Medeiros Jessica de , Da Silva Ádria Cristina , Corso Pereira Mônica
Published: December 2022

Background: Exacerbations are pivotal events in the natural history of patients with non-cystic fibrosis bronchiectasis (NCFB), since they have a negative impact on the functional evolution of these individuals. The daily symptoms of patients with NCFB show great variability, which negatively affects their self-perception of symptoms and exacerbations. The aim of this study was to identify daily symptoms in patients with NCFB, and to investigate whether there is a correlation between the frequency of self-reported exacerbations and events defined according to the criteria established in the literature to define exacerbation in bronchiectasis.Methods: This observational and prospective study was carried out in outpatient clinics of a Brazilian public university hospital. Over 24 weeks, patients completed a diary in which daily symptoms, self-reported exacerbations, and demands for medical care for respiratory symptoms were recorded. The instruments used (diary and symptom scores ranging from 0 to 12) were developed by the researchers. The participants also answered questionnaires mMRC, Leicester’s, and St. George's Respiratory (SGRQ).Results: Twenty-eight patients returned the diary, their mean age was 54 years, and 50% out of them were classifiedas mild by the FACED score. Cough (64%) and expectoration (62%) were the most frequent symptoms. Correlations were found between the stability score and the mMRC (r=0.4727, p=0.011) and SGRQ (r=0.6748, p<0.0001) questionnaires. The number of self-perceived exacerbations (24) was significantly lower than exacerbations using the exacerbation consensus (63) (p<0.01). Additionally, no correlation was found between these two criteria. Conclusions: There was great variability of symptoms among the individuals sampled, and even for the same individual, over time. Patients had low self-perception of exacerbations, which suggests that strategies aimed at improving this self-perception may contribute to the early detection of exacerbations.

Published: December 2022

Background and Objectives:

In transpapillary biliary drainage, metal stents (MSs) exhibit a lower incidence of a biliary obstruction than plastic stents (PSs). However, few studies have compared recurrent biliary obstruction (RBO) when MSs and PSs are used in EUS-guided hepaticogastrostomy (EUS-HGS) and choledochoduodenostomy (EUS-CDS). We retrospectively evaluated the RBO for both stents in each procedure.

Patients and Methods:

Between November 2012 and December 2020, 85 and 53 patients who underwent EUS-HGS and EUS-CDS for unresectable malignant biliary obstruction, respectively, were enrolled. Factors associated with RBO were assessed. Clinical outcomes were compared between the MS and PS groups using propensity score matching.

Results:

The clinical success rate and procedure-related adverse events were similar in the MS and PS groups. Multivariate analysis identified the use of PS as a factor associated with RBO (EUS-HGS, P = 0.03; EUS-CDS, P = 0.02). After matching, the median time to RBO in EUS-HGS (MS: 313; PS: 125 days; P = 0.01) in the MS group was longer than that in the PS group. The cumulative incidence of RBO at 1, 3, and 6 months in the MS group was significantly lower than that in the PS group for EUS-HGS (MS: 4.0%, 8.2%, and 8.2%; PS: 12.4%, 24.9%, and 39.5%, respectively, P = 0.01).

Conclusions:

MS exhibited a lower rate of RBO than PS for EUS-HGS and EUS-CDS.
Malignancy with benign course – basaloid squamous cell carcinoma
Authors: Sarkar Avik Dey , Mandal Radhakrishna , Daulat Thakur Sanjay Kumar
Published: December 2022

A 45-year-old male presented with a 3 mm × 3 mm painless, slow-growing, gelatinous, freely mobile, benign-looking mass on the temporal side of the limbus in the conjunctiva of the right eye for 1 year. Other ophthalmic findings were unremarkable. Orbital computed tomography showed no orbital involvement or localized lymphadenopathy. The mass was excised with a healthy collar of 3 mm, and the sample was sent for histopathological examination (HPE). The patient was followed up with usual signs of healing. The case took a surprising turn when HPE showed areas of keratin pearls of squamous origin along with lobules of malignant cells displaying nuclear palisading and basal cell nests, thereby diagnosing basaloid squamous cell carcinoma of the conjunctiva. Positive staining for 34βE12 and negative for BCL-2 on immunohistochemistry confirmed it. Identification is extremely important due to its aggressive course with frequent recurrences and distant metastasis. It has been reported only thrice before in the literature.
Sulcus implantation of single-piece foldable acrylic intraocular lens after posterior capsule tear during phacoemulsification
Authors: Kumar Sunil , Shilpy Neha , Gupta Rajiv Kumar
Published: December 2022

Background:

Posterior capsule tear (PCT) during phacoemulsification affects the type, site, and timing of intraocular lens (IOL) implantation.

Aim:

The aim was to evaluate the visual outcomes and complications following sulcus implantation of single-piece foldable acrylic IOL after PCT during phacoemulsification.

Setting and Design:

The retrospective observational study was conducted at a tertiary care center in eastern India.

Methods:

Records of patients between July 2017 and March 2020 were reviewed. Thirty-six eyes of 36 patients, in whom PCT had occurred during phacoemulsification, were included.

Statistical Analysis Used:

Microsoft Excel 2007 and SPSS 108 software were used. Preoperative and postoperative visual acuity was compared using paired t-tests. Postoperative visual outcomes and complications were assessed in percentage.

Results:

Postoperative visual acuity was ≥6/12 in 22 (61.11%) patients on day 1 and 30 (83.33%) patients on day 30, with a statistically significant improvement compared to preoperative vision (P < 0.05). On the first postoperative day, corneal edema was seen in 8 (22.22%) patients, increased anterior chamber reaction in 5 (13.89%) patients, and raised IOP in 4 (11.11%) patients. After 3 months, 2 (5.56%) patients needed antiglaucoma medications for IOP control, 1 (2.78%) had iridocyclitis, and 1 (2.78%) had chronic cystoid macular edema. The mean follow-up duration was 17.44 ± 12.15 months (range: 3–46 months).

Conclusion:

To conclude, sulcus implantation of posterior chamber IOL during phacoemulsification surgery complicated with PCT may be considered if the adequate lens is not available, and sufficient capsular support exists. Our study revealed a good final visual acuity with minimal complications, though more research to ascertain our results is warranted.

Authors: Radhakrishnan Rahul , Nagar Vidya , Suryawanshi Nitin , Mehendale Advait , D’souza Marius , Kantak Divya , Akhtar Tahir , Priyadarshini Arpita
Published: December 2022

Background:

Sparse data are available from India regarding the impact of metabolic syndrome (MetS) on hospital outcomes in patients presenting with acute myocardial infarction (AMI). Therefore, the present study was conducted to evaluate the burden of MetS in patients with AMI and its impact on the hospital outcomes.

Methods:

This single-centre, observational, cross-sectional study was conducted in the medicine and cardiology intensive care units of a tertiary care hospital in Mumbai, Maharashtra, in patients presenting with AMI.

Results:

Among the 210 patients (mean age 56.5 ± 5.2 years; 67.1% males) with AMI studied, 101 (48.1%) fulfilled the criteria for MetS. No significant difference was seen in the age (P = 0.70) and gender (P = 0.55) in patients with and without MetS. Anterior wall was the most common site of infarction; heart failure was the most common complication in both the groups. Case fatality was significantly higher in patients with MetS (P = 0.003). Heart failure was the most common complication in all non-survivors. The duration of hospital stay was significantly longer (P < 0.0001) in patients with MetS.

Conclusions:

We observed that MetS was evident in almost half (48.1%) of the patients presenting with AMI. The presence of MetS significantly increased the risk of complications, fatality and duration of hospital stay in patients with AMI.

Authors: Sahoo Nibedita , Ghosh Urvashi , Mohapatra Debahuti , Dehuri Priyadarshini
Published: December 2022

Aim and Objectives:

The study aims to categorize malignant small round cell tumors (MSRCTs) originating in various sites of the body with the objective of utilization of cytomorphological features and ancillary techniques.

Study Design:

It is a cross-sectional study conducted over a time span of 3 years (2017–2020). 33 cases of tumors with round cell morphology were evaluated by fine needle aspiration cytology (FNAC).

Materials and Methods:

The application of cell block preparation supported by immunohistochemistry aided in the categorization of 23 cases with definite diagnosis and the rest were reported as MSRCTs.

Results:

Among the categorized 23/33 cases, the most common diagnosis was Ewing’s sarcoma (7/23) followed by 6 cases of lymphoma. There were 2 cases each of rhabdomyosarcoma and Langerhans cell histiocytosis (LCH) and 1 case each of neuroblastoma, desmoplastic small round cell tumor (DSRCT), myeloid sarcoma, neuroendocrine tumor of pancreas, plasmacytoma, and small cell carcinoma. Histopathology confirmation was available in 24/33 cases. Among the categorized tumors (23/33), biopsy correlation was available in 19 cases, of which concordant result was seen in 17 cases (89.47%), which were 6 cases of lymphoma, 5 cases of Ewing’s sarcoma (EWS), 2 of rhabdomyosarcoma, and 1 each of neuroblastoma, small cell carcinoma, DSRCT, and LCH. Discordant result was seen in one case of rhabdomyosarcoma and a case of synovial sarcoma reported as extraskeletal EWS in cytology. Out of the uncategorized cases reported as MSRTCs, histopathology was available in 5 cases which were diagnosed as rhabdomyosarcoma (1 cases), lymphoma (1 case), amelanotic melanoma (1 case), and extraskeletal EWS (2 cases).

Conclusion:

Categorization of MSRCTs should be done to implement appropriate therapeutic protocol. FNAC provides a rapid diagnosis contributing immensely for the timely management of the patient. Detailed cytomorphological evaluation serves as a guide for further evaluation by ancillary techniques leading to definitive diagnosis.

Authors: Mohammed-Durosinlorun Amina , Sani Fatima , Abubakar Rukayya , Egwu Funmi , Mohammed C , Taingson M
Published: December 2022

Context:

The potential benefits of exercise to pregnant women and their unborn children are immense, yet regular exercise prescription may not be the norm.

Aims:

Our study aimed to investigate the perceptions and practices of obstetric care providers regarding exercise in pregnancy.

Materials and Methods:

The study was a cross-sectional survey done in Kaduna state between July and December 2020. A pretested questionnaire was given to obstetric care providers and information was obtained about demographics, professional and facility characteristics of respondents, their perceptions, and practices related to exercise in pregnancy, and information they routinely give pregnant women regarding exercise. Descriptive analysis was done using frequencies, percentages, mean, and standard deviation.

Results:

There were 265 respondents with a mean age of 34.23 ± 9.29 years. They were mostly females (215, 82.1%), married (171, 65.3%), Muslim (137, 52.3%), and Hausa (107, 40.8%). There were more nurses (153, 58.4%) from the public (212, 80.9%) and tertiary (133, 50.8%) health facilities. Almost all respondents agreed that exercise during pregnancy was beneficial (258, 98.5%). The commonest indication for exercise was cited as obesity and diabetes, whereas it was mostly contraindicated with bleeding while pregnant. The commonest barriers to exercise in pregnancy were the fear of pregnancy complications, inadequate knowledge, and high workload.

Conclusion:

Healthcare workers in this study generally had positive perceptions and practices toward exercise during pregnancy, except for the fact that they feel pregnant women should avoid strength-building exercises, and do not usually recommend individualized programs. Local guidelines need to be developed for EIP and providers better trained.

Published: December 2022

Context:

Facial height measurements may aid in predicting occlusal vertical dimension (OVD).

Aim:

To compare facial third measurements among individuals with healthy occlusions for a predictive ratio for occlusal vertical dimension determination.

Setting and Design:

A cross-sectional prospective observational study at the Dental Clinic of Aminu Kano Teaching Hospital. Sampling was purposive.

Materials and Methods:

A digital caliper was used to measure the upper facial height (UFH), the midfacial height (MFH), and the lower facial height (LFH) of 103 participants.

Statistical Analysis Used:

The data collected were analyzed with IBM Statistical Package for the Social Sciences (SPSS) version 25. The level of statistical significance was set at P ≤ 0.05.

Results:

There were 69 male (67%) and 34 female (33%) members in the cohort analyzed. The ages of the participants ranged from 18 to 58 years, with a mean age of 27.3 ± 6.8 years. The UFH ranged from 60 to 110 mm with a mean value of 82.2 ± 9.8 mm. The MFH ranged from 55 to 100 mm with mean value of 74.6 ± 9.9 mm. The LFH ranged from 60 to 90 mm with a mean of 73.2 ± 7.4 mm. There was a significantly positive correlation between UFH and LFH (r = 0.22). This was similar to that of MFH and LFH (r = 0.61). The best fit model equation for the prediction of LFH was found to be LFH = 31.495 + (0.442 × MFH).

Conclusions:

This study found MFH to be a predictable factor for LFH estimation which can be used for OVD determination.

Authors: Adamu A. , Isezuo KO , Ali M. , Abubakar FI , Jiya FB , Ango UM , Yunusa EU , Bello MM
Published: December 2022

Context:

Exclusive breastfeeding (EBF) is a key to achieving sustainable development goals (SDGs), but its practice has remained low in Nigeria, despite the strong evidences in support of EBF for the first six months of life.

Setting and Design:

This was a nine months descriptive cross-sectional study carried out among nursing mothers with children 6–24 months attending pediatric follow-up clinic and family health clinic of Usmanu Danfodiyo University Teaching Hospital, Sokoto.

Materials and Methods:

Interviewer administered questionnaire was used to obtain information on the sociodemographic characteristics and EBF practices of mothers.

Statistical Analysis Used:

Data were analyzed using SPSS version 20.

Results:

A total of 240 mothers were interviewed. The mean age of the mothers was 29.7 ± 6 years. All the respondents breastfed their children, 82 (34.2%) practiced EBF for six months. Higher level of maternal education (P = 0.001), ANC attendance (P = 0.001), maternal occupation (P = 0.007), hospital delivery (P = 0.007) significantly influence the practice of EBF for six months.

Conclusion:

EBF practice was sub optimal. Thus, improving utilization of antenatal care, female education, and hospital delivery are crucial interventions to increase EBF practice toward achieving SDG-2 and 3 in Sokoto.
Efficacy and Safety of Pulsed Electromagnetic Field (PEMF) Stimulation in the Treatment of Urinary Symptoms in Women with Urinary Incontinence
Authors: Madani Ali Hamidi , Chafjiri Fatemeh Mohammadalizadeh , Esmaeili Samaneh , Madani Zahra Hamidi , Leili Ehsan Kazemnejad
Published: December 2022

Purpose:

There are different approaches to the treatment of urinary incontinence (UI), including pharmacological, nonpharmacological, and surgical methods. Pulsed electromagnetic field (PEMF) stimulation is a nontraditional and noninvasive type of treatment, which is gaining increasing popularity in healthcare departments for UI treatment.

Materials and Methods:

In this quasi-experimental study, women (age ≥21 years) with lower urinary tract symptoms (LUTS) were assigned to three groups regarding the UI type (urgency, stress, and mixed UI). The Bristol Female LUTS (BFLUTS) questionnaire was used to evaluate the UI severity. The patients were treated with PEMF stimulation twice per week up to 6 weeks. The results were evaluated at three and 6 months posttreatment.

Results:

Ninety women completed 6 months of follow-up in this study. The mean age of the participants was 58.5 ± 13.9 years. Of 90 patients, 61 (67.8%) had mixed UI, 22 (24.4%) had urge UI, and 7 (7.8%) had stress UI. There were significant differences between the groups regarding the frequency of leakage from baseline to 3 and 6 months after treatment; the reduction of leakage severity was only nonsignificant in the stress UI group (P = 0.368). Based on the results, the number of used pads reduced from 4.18 ± 3.00 to 1.08 ± 2.03 (P < 0.001); this reduction was also significant in each of the groups. The mean BFLUTS score reduced from 7.42 ± 2.53 at baseline to 5.56 ± 2.37 and 3.00 ± 2.33 at 3 and 6 months after treatment, respectively (P < 0.001). No significant complications were detected in the groups.

Conclusion:

The PEMF stimulation is a safe and effective approach for reducing the symptoms of patients with UI. The best response to treatment was reported at 6 months posttreatment. Therefore, it is recommended to use PMEF stimulation as a noninvasive treatment along with routine therapies.

Об интегрируемости уравнений динамики в непотенциальном силовом поле
Authors: Kozlov Valery Vasil'evich
Published: December 2022

Рассматривается круг вопросов, связанных с точным интегрированием уравнений движения механических систем в непотенциальном силовом поле (часто называемых циркуляционными). Подход к интегрированию основан на теореме Эйлера-Якоби-Ли: если $n$ - число степеней свободы, то (с учeтом сохранения фазового объeма) для точного интегрирования необходимо иметь ещe $2n-2$ первых интегралов и полей симметрий, находящихся в некоторых естественных отношениях. Указаны случаи движения в непотенциальном поле, интегрируемые с помощью разделения переменных. Обсуждаются геометрические свойства систем с ненeтеровыми полями симметрий. Указаны примеры существования неприводимых полиномиальных интегралов третьей степени по импульсам. Рассмотрена задача об условиях существования однозначных полиномиальных интегралов циркуляционных систем с двумя степенями свободы и торическим пространством положений. Показано, что в типичном случае уравнения движения вообще не допускают непостоянных полиномиальных интегралов.

Approximability results for the $p$-centdian and the converse centdian problems
Authors: Chen Yen Hung
Published: December 2022

Given an undirected graph $G=(V,E)$ with a nonnegative edge length function
and an integer $p$, $0 < p < |V|$, the $p$-centdian problem is to find $p$
vertices (called the {\it centdian set}) of $V$ such that the {\it
eccentricity} plus {\it median-distance} is minimized, in which the {\it
eccentricity} is the maximum (length) distance of all vertices to their nearest
{\it centdian set} and the {\it median-distance} is the total (length) distance
of all vertices to their nearest {\it centdian set}. The {\it eccentricity}
plus {\it median-distance} is called the {\it centdian-distance}. The purpose
of the $p$-centdian problem is to find $p$ open facilities (servers) which
satisfy the quality-of-service of the minimum total distance ({\it
median-distance}) and the maximum distance ({\it eccentricity}) to their
service customers, simultaneously. If we converse the two criteria, that is
given the bound of the {\it centdian-distance} and the objective function is to
minimize the cardinality of the {\it centdian set}, this problem is called the
converse centdian problem. In this paper, we prove the $p$-centdian problem is
NP-Complete. Then we design the first non-trivial brute force exact algorithms
for the $p$-centdian problem and the converse centdian problem, respectively.
Finally, we design two approximation algorithms for both problems.
Proximity, remoteness and maximum degree in graphs
Authors: Dankelmann Peter , Mafunda Sonwabile , Mallu Sufiyan
Published: December 2022

The average distance of a vertex $v$ of a connected graph $G$ is the
arithmetic mean of the distances from $v$ to all other vertices of $G$. The
proximity $\pi(G)$ and the remoteness $\rho(G)$ of $G$ are the minimum and the
maximum of the average distances of the vertices of $G$, respectively.
In this paper, we give upper bounds on the remoteness and proximity for
graphs of given order, minimum degree and maximum degree. Our bounds are sharp
apart from an additive constant.
Rerunning OCR: A Machine Learning Approach to Quality Assessment and Enhancement Prediction
Authors: Schneider Pit , Maurer Yves
Published: December 2022

Iterating with new and improved OCR solutions enforces decision making when
it comes to targeting the right candidates for reprocessing. This especially
applies when the underlying data collection is of considerable size and rather
diverse in terms of fonts, languages, periods of publication and consequently
OCR quality. This article captures the efforts of the National Library of
Luxembourg to support those targeting decisions. They are crucial in order to
guarantee low computational overhead and reduced quality degradation risks,
combined with a more quantifiable OCR improvement. In particular, this work
explains the methodology of the library with respect to text block level
quality assessment. Through extension of this technique, a regression model,
that is able to take into account the enhancement potential of a new OCR
engine, is also presented. They both mark promising approaches, especially for
cultural institutions dealing with historical data of lower quality.
Current state, issues and perspectives of construction waste recycling in Ukraine
Authors: Hudym Milena , Kononenko Hanna , Izbash Yuriy
Published: December 2022

The article analyzes the problem of construction and demolition waste disposal in Ukraine, which is especially relevant due to the increasing number of housing renovation projects and the intensification of national construction projects. Construction waste accounts for almost a third of the waste generated in most developed countries. The most efficient disposal method is recycling, i.e. recycling of secondary building resources (SBR). However, the share of recycled construction waste in Ukraine lags far behind developed countries (it is about 6% of its total volume). The high level of waste generation and low rates of its use as secondary raw materials (SRM) have led to the fact that a significant amount of solid waste accumulates annually in the industrial and civil sectors of Ukraine, only a small part of which is used as SRM, the rest ends up in landfills. The difference between waste management in Ukraine, compared with other developed countries, is in the large volumes of waste generation and the lack of infrastructure to recycle it. The issues of the environmental impact of construction waste are considered, and the main cost-effective technologies for processing SBR are identified and considered in this research. With the help of market mechanisms and government regulations, these technologies may become promising for investment and their development will be beneficial for small and medium-sized businesses. Perspective areas of construction waste recycling in order to obtain demanded products are presented; existing advantages and technologies of processing SRM are also considered: solid waste processing, biothermal composting, wood waste processing, recycling of construction waste and metallurgical slag, etc.
Валерій Посвалюк та Тимофій Докшицер: методичні стратегії професійної майстерності трубача
Authors: Ло Чже
Published: December 2022

Провідні трубачі сучасності Т. Докшицер та В.Посвалюк у процесі виконавської та педагогічної діяльності сформували та втілили у практику неповторну методику виховання успішних виконавців. Ці творчі постати зближує невід’ємність двох складових, двох функцій у просторі культури: виконавець-викладач. Методики їх викладацької діяльності представлені у дидактичних матеріалах, спеціальних методичних роботах, у монографіях і навіть у мемуарній літературі. Їх педагогічні системи гуртувалися навкруги найкращих здобутків духового виконавства та викладання, що розвивали трубачі Київської школи у першій половині ХХ століття. Їх, як вірних послідовників фундаторів трубної педагогіки, відрізняє синкретизм творчості та технології, а відтворення музичного звуку у виконавському та навчальному процесах дорівнюється до акту Божественного Творіння. В основі педагогічної системи кожного – індивідуальна група вправ, але вони носять змістовий характер, семантично навантажені і спрямовані на опрацювання не лише механіки, а й створення осмисленого підґрунтя виконавської діяльності. Важливе місце відведено проблемним ситуаціям, евристичним пошукам вірного відтворення різних штрихів, прагненню осмислення різних виконавських прийомів, розуміння важливих відмінностей, укладених у прийомах атаки, звуковедення, та засобів поєднання звуків. Саме Т. Докшицер та В. Посвалюк розробили методику формування інтелектуального підґрунтя виконавській діяльності молодих виконавців, не обмежуючи шлях до майстерності гри трубача лише технічними аспектами.
Комплімент як спосіб мовної реалізації етикетної комунікації
Authors: Зюмрютдал Ірина
Published: December 2022

Сучасне мовознавство характеризується прагненням до пізнання складної природи людського спілкування, в якому мова, втілена в мовленні, є важливим засобом соціальної взаємодії, що дозволяє людям впливати на розумову та практичну діяльність один одного. Успішне вивчення мовлення як однієї з форм соціальної поведінки, виявлення загальних закономірностей комунікативного процесу є неможливим без глибокого комплексного аналізу окремих мовленнєвих явищ у всій повноті численних аспектів (мовного, соціально-психологічного, когнітивного, етнокультурного тощо). Спілкування - це соціально-психологічне явище, яке вміщує в себе багатоаспектність духовних та матеріальних форм життєдіяльності людини та є її основною потребою. В основі кардинальних змін, що відбуваються сьогодні в науці про мову, лежить діяльнісна методологія, у рамках якої людська комунікація вивчається як системно організована діяльність, а акт мовної  комунікації розглядається як конкретна мовленнєва дія, що становить собою цілісну сукупність дій – взаємодій. У статті розглядається етикетний комплементарний мовленнєвий акт, як явище, що поєднує в собі такі категорії, як мовленнєва дія, гендерна та соціально-психологічна взаємодія, спосіб мовної реалізації етикетної комплементарної мовленнєвої дії в украінській мові.
Methodology of establishing communications with corporate consumers in the construction materials market
Authors: Oklander Tetyana , Shcherbyna Oleh
Published: December 2022

Modern world dictates its own conditions, and every entrepreneur must master the art of sales strategy, not only master it but also win the battle for profits and market share. Today, strategy is a long-term action plan aimed at achieving an enterprise’s global goals. Prior to forming a detailed by-element sales strategy, special attention must be paid to personnel policy because a large part of the success depends on a manager`s individual professional qualities, expertise, communication skills, knowledge, and practice in implementing sales techniques, etc. The authors explore the influence of various channels on the organization's sales volume and suggest basic tasks to form a “direct” selling strategy. The significance of a manager’s individual qualities as a mandatory prerequisite for the creation of a successful sales strategy has been established. Special attention is paid to the most effective sources of gathering information about construction objects of various types, which, in turn, allows constant monitoring of the sequence of works, acquisition of proper paperwork from the developer, determining constructional features of a building, and figure out construction technologies used on the object. Such an approach allows for reducing significantly the time spent on the preliminary stage of the sales – search, collection, and structuring information about the potential clients. An analysis of the received data on the implemented strategy was carried out, including all the mentioned components, which allowed, firstly, to cover the entire ground without losing the opportunity of the “touch” with every potential client and, secondly, to be fully prepared for the meeting with the client, which will be a solid foundation for sales techniques. On the basis of the received data, the effectiveness of the considered strategy and the sales department as a whole is evaluated. As a result, the most effective algorithm for materials sales in the construction market is suggested.

Búsqueda de paz social mediante la justicia indígena en el cantón Saraguro.
Authors: Tixi Torres Diego Fabricio , Cajo Calle Ivonne Patricia , Sarango Saca Zoila Narciza
Published: December 2022

En el año 2008, la Constitución del Ecuador creo un precedente en la historia del país, donde se destaca el pluralismo jurídico reconociendo la justicia indígena en nuestro país, lo cual permite que los ciudadanos de los pueblos indígenas tengan responsabilidades, ya que las autoridades indígenas son capaces de manejar y resolver cualquier acción que esté en contra de la paz social de su comunidad; por lo cual se establece que el cantón Saraguro existen 12 comunidades, las cuales se someten a la aplicación de la justicia indígena, buscando así que los índices delincuenciales de este cantón disminuyan en comparación con otros cantones de la provincia de Loja. Para la realización de esta investigación se utilizó el método cualitativo-cuantitativo.

Authors: Cacpata Calle Wilson Alfredo , Mena Córdova Thalía Rubí , Gil Betancourt Antonella Stefanía
Published: December 2022

La temática principal busca determinar si las autoridades de la justicia indígena deberían o no tener la facultad de consultarle a la Corte Constitucional la constitucionalidad o convencionalidad de una norma de derecho propio que pretenden aplicar en un caso concreto y sobre la cual la autoridad indígena advierte una posible inconstitucionalidad o convencionalidad. La metodología utilizada es la aplicación de entrevistas a diferentes personalidades. Se concluyó que el informe de leyes por parte de las autoridades indígenas podría darles la oportunidad de que la Constitución le otorgue a la justicia ordinaria para consultar la tramitación de un caso concreto.
