Authors: Dore Mina Amiri , Torabizadeh Camellia , Keshtkaran Zahra
Published: June 2022

Background & Objective: Every operating room has been associated with a variety of occupational hazards, but not many studies have been conducted to assess and address these hazards. We used a qualitative approach to explore operating room personnel’s experiences of workplace hazards and how these hazards threaten their occupational safety and health (OSH).

Methodology: This qualitative study was conducted in five teaching hospitals in the south-west of Iran from February 2019 to March 2021. The sample was 24 operating room personnel who were selected under convenient sampling technique. Data were collected using semi-structured, individual interviews, document review and non-participant observation. The collected data were analyzed according to the qualitative content analysis method using MAXQDA v. 2020.

Results: After prolonged analysis of the data, the researchers extracted 644 codes, 13 subcategories, 4 categories, and 1 main theme. The main theme of the study was working in a context of occupational hazards.

Conclusions: Operating rooms are full of potential dangers, which, when combined with the personnel’s negligence and management inefficiencies, increase the risk of occupational health and safety. Therefore, making working conditions safe by providing adequate personal protective equipment (PPE), in-service training, and identifying and managing the causes of personnel negligence are recommended. Moreover, strategies should be introduced to manage stress and conflicts among the healthcare personnel, thus controlling psychological hazards.

Published: June 2022

Extraction of Copper ion from its water solutions using plant waste (compost), sludge and Bentonite metal as cheap natural adsorbed materials. It was found that Copper ion extraction was based on concentration of  Copper  and amount of the adsorbed materials. Highest amount of adsorption was obtained at 180 µg Cu ml-1 as Bentonite, plant waste and sludge respectively. Thermal equilibrium of the system was studied by Langmuir equation, R2 gave a good linear relationship  in succession. Maximum regulatory capacity and regulatory capacity at equilibrium is 1.0 , 0.99 and 0.96 to  plant waste, sludge and Bentonite respectively, as the preference coefficient constant calculated by the Langmuir equation indicate that adsorption is preferable and irriversible for plant waste and sludge while not preferentially and reversible for bentonite. G adsorption reactions were automatic for the Bentonite metal, while for plant waste and sludge  non-spontaneous reaction and needs extra activation energy. It is clear from the above that the use of natural materials in the extraction of copper ion is a very effective method and it is an inexpensive and friendly methods envirooment.

Published: June 2022

The Covid-19 pandemic has set new challenges in the health care system. The strict limitations in movement of people during the pandemic
changed the structure of oral health care system worldwide including India. The novel coronavirus is highly transmissible and contagious with the
highest risk while working in the patient's mouth. Patients had fear and anxiety visiting a dental setup for their dental complaints. Teledentistry
provided access to oral healthcare in these unprecedented and extraordinary circumstances.
To check for utilization of Teledentistry services during the Covid-19 pandemic a retrospective study was conducted. The data collected from
patients calling for dental consultations was retrieved from the hospital records of Faculty of Dentistry, Jamia Millia Islamia (August 2020 to June
2021). 1176 patients called during the covid-19 pandemic period for enquiry and various dental chief complaints. Their demographic
characteristics, reasons for consultation and advice given were analyzed. Out of the 1176 patients, there were 43, 6% males and 56, 4% females.
The mean age of the patients was 33.39±14.98 years. The most common consultation was regarding dental pain (30.10%). 27.15% patients
enquired about the reopening of dental health services. 41.4% patients were advised medications for their dental complaints. Teledentistry in the
covid-19 pandemic lockdown had proven to be helpful for rendering emergency prescriptions and essential preventive care.

Published: June 2022

Introduction: Misoprostol a potent uterotropic and uterotonic agent which causes cervical effacement &dilatation and stimulates myometrial
contractions, is effective in terminating intrauterine foetal death. The Objective of the study was to compare the effectiveness of oral misoprostol
versus vaginal misoprostol in termination of all cases of intrauterine foetal death and its outcome. Details of induction –delivery interval and
maternal morbidities were also analysed. A prospective comparative study.Al Methodology: l pregnant women indicated for termination of
intrauterine foetal death satisfying both inclusion and exclusion criteria being admitted in our Labour Room during the period of this study were
included.Total 60 patients were included out of which 30 receiving oral misoprostol forms the rst group and the other 30 receiving vaginal
misoprostol forms the second group. For the rst group, 200 mcg of oral misoprostol tablet was dissolved in 200ml water and 25 mcg, ie. 25ml of
the solution was given rst and then every two hours till pain occurs. Second group was given 25 mcg of vaginal misoprostol every 4 hourly.
Induction-delivery interval and maternal morbidities were compared in both groups. The me Results: an induction-delivery interval was higher in
Oral misoprostol when compared to vaginal route and this difference was found to be statistically signicant (p <0.001). However, the oral route
was much easier when compared to vaginal route.The maternal morbidities like diarrhoea, fever, PPH, shivering, vomiting and tachysystole were
similar in both groups.There were no cases of uterine rupture in the study. The effe Conclusion: ctiveness of different routes of administration was
signicant in our study with signicantly shorter mean induction-delivery interval in vaginal route compared to oral route.Although there were few
maternal morbidities seen in both groups, there were no statistically signicant differences between two groups

Authors: Das Debanu , Dasgupta Indraneel , Das Subhendu
Published: June 2022

Introduction: Indwelling urinary tract catheterization (IUTC) is a very common intervention frequently required in hospitalized patients. It is
estimated that 10-12% of hospital patients and four per cent of patients in the community have urinary catheters in situ at any given time.1
Nosocomial UTIs (urinary tract infections) develop in ve per cent of catheterized patients per day in the US, with associated bacteremia in four per
cent and as many as 80% are a consequence of urinary catheters. Research has shown that just reminding physicians to remove unnecessary urinary
catheters can signicantly reduce the duration of urinary catheterization and the catheter associated urinary tract infection (CAUTI) rate in a
hospital.
Aims:To Study of Infection Rate due to Folleys Catheter Insertion in ED, Medical Ward and ICU.
Methods: This was a single centre observational, retrospective cohort study from tertiary care hospital in Kolkata, India from May 2021 –
JANUARY– 2022 were included no Past History of UTI, No Past History of renal Infection and No Previous Indwelling Folleys Catheter.
Result: In Critical Care (ICCU) Group, 166 (21.3%) patients had CAUTI. In Emergency Group, 297 (42.9%) patients had CAUTI. In Medical
Ward Group, 332 (30.1%) patients had CAUTI. Association of CAUTI with Group was statistically signicant (p<0.0001). In Critical Care (ICCU)
Group, 166 (21.3%) patients had Culture. In Emergency Group, 297 (42.9%) patients had Culture. In Medical Ward Group, 332 (30.1%) patients
had Culture. Association of Culture with Group was statistically signicant (p<0.0001)
Conclusion: The rate of CAUTI in emergency dept is higher than rate of CAUTI in other medical ward of ICCUs. and we also see that rate of
CAUTI in ICCU is much lesser than rate of CAUTI in other medical ward or emergency

Authors: Gupta Bhumika , Sharma Aparna , Pant Reena
Published: June 2022

Introduction: A signicant proportion of pregnancies presenting with early bleeding end up in poor outcome (abortion). Present study aim to
evaluate CA-125 level as diagnostic and prognostic indicator in threatened abortion. Material and Methods: This Hospital based prospective
cohort study was conducted included 75 cases of threatened abortion and 75 controls. “Threatened abortion” group included females presenting
with 6 to 12 weeks gestation, with a demonstrable fetal heartbeat on ultrasonography, with complain of vaginal bleeding with or without abdominal
cramps. 'Threatened abortion' group females were followed and divided into two groups based on their outcome- Threatened abortion ended with
Abortion (TAEA) or Threatened abortion with ongoing pregnancy (TAOP). Results: Out of the 75 patients with threatened abortion, 27 (36%)
ended with abortion. The mean CA-125 levels were found to be signicantly higher (p<0.001) in TAEAgroup (89.44 U/ml) as compared to TAOP
group (44.69 U/ml) and Control group (24.73 U/ml). Ahigh Area under the ROC curve of 0.916 (95% CI- 0.828 – 1.00) indicated that CA-125 is a
good predictor of abortion among females presenting with threatened abortion (p<0.001). At the critical cutoff of 58.5 U/ml, CA-125 had
sensitivity and specicity of 88.9% and 93.7% respectively for predicting abortion. Conclusion: Evaluation of maternal serum CA-125 levels in
females with early pregnancy bleeding would allow closer and individualized antenatal monitoring, earlier diagnosis, and timely interventions,
which could potentially improve pregnancy outcomes.

Published: June 2022

The most common congenital defects of the orofacial region involve the clefts of the lip, alveolus and palate which lead to a signicant number of
skeletal and soft tissue deformities of the lips, nose and facial bones. The clefts may be quite extensive , thus presenting a greater surgical challenge
in the approximation of anatomic structures. Restoration of the normal anatomy and function serves as the primary goal of treatment in these
patients. Presurgical Maxillofacial Orthopedics or Presurgical Nasoalveolar moulding is thus resorted to, with the help of custom made appliances
and utilization of the growth potential of the baby. After an extensive search of literature, this review compiles and discusses the history and the
principle behind PNAM along with the fabrication and application of the plate used to achieve nasoalveolar moulding .

Authors: Suthar Tarachand , Saini Santosh , Kumar Bohra Arvind
Published: June 2022

Introduction: Degenerative hip disorders are one of the most common and debilitating musculoskeletal disorders with increased morbidity and
decreased quality of life. Total hip arthroplasty is a modern surgical procedure which has relieved patients from incapacitating pain arising from the
hip joint.
Many surgical approaches to hip have evolved over the period of time for Total hip arthroplasty. Surgical approaches differs mainly in position of
patient in supine or lateral and whether the hip is dislocated anteriorly or posteriorly. The choice of surgical approaches is largely depending on
personal preference and training. Gibsons posterior and hardinges direct lateral approach are the two most commonly used surgical approaches.
To evaluate the Clinical and Functional outcomes of Total Hip Replacement after Harding's approach Harris Hip Score and radiological assessment
was used. Harris Hip Score comprised of Pain, Functional disabilities, Deformity, Range of movements
Objective: To study the clinical, radiological and fuctional outcome and complications associated with total hip arthroplasty through hardinge
approach.
Materials And Methods: A Prospective study was carried out from July 2019 to December 2020 under Department of Orthopaedics, SRG
Hospital and Medical College, Jhalawar including 58 patients who fullled the inclusion criteria operated for total hip arthroplasty through
hardinge approach. Patient's follow up was up to 12 months.
Results: The functional assessments were made with modied Harris Hip scores. The results showed excellent in 41 patients (70.68%), good in 15
patients (25.86%), Fair in 2 patients (3.44%). There are no poor results in our study. Hardinge's approach has no incidence of prosthesis dislocation.
Conclusion: The Hardinge's approach provides easy access to the hip joint and provides excellent exposure of both acetabular and proximal femur.
Hardinge's approach is a good approach for the outcome of the Harris hip score with no major complication with satisfactory clinical, functional
and radiological outcomes. Hardinge's approach has no incidence of prosthesis dislocation.
Development and validation of comprehensive closed formulas for atmospheric delay and altimetry correction in ground-based GNSS-R
Authors: Nikolaidou Thalia , Santos Marcelo , Williams Simon , Geremia-Nievinski Felipe
Published: June 2022

Radio wave propagation involved in Global Navigation Satellite System Reflectometry (GNSS-R) is subject to atmospheric refraction. Even for ground-based tracking stations, in applications such as coastal sea-level altimetry, the interferometric or reflection-minus-direct effect might be significant. Although atmospheric propagation delays are best investigated numerically via raytracing, including reflections, such a procedure is not trivial. We have developed simpler closed formulas to account for atmospheric refraction in ground-based GNSS-R, validated against independent raytracing. We provide specific expressions for the linear and angular components of the atmospheric interferometric delay and corresponding altimetry correction components, parameterized in terms of refractivity and bending angle. Assessment results showed excellent agreement for the angular component and good for the linear one. For the conditions analyzed, about half of the delay was found to originate above the receiving antenna, for satellites at low elevation angles. We define the interferometric slant factor used to map interferometric zenithal delays to individual satellites. We also provide an equivalent correction for the effective satellite elevation angle such that the refraction effect is nullified. Lastly, we present the limiting conditions for negligible atmospheric altimetry correction (sub-cm), over domain of satellite elevation angle and station height. For example, for a station five meters above sea level, observations for satellites below 20° elevation angle are subject to more than  one centimeter of atmospheric altimetry error.
Approximate Inverse of the Rao-Wilton-Glisson Basis Functions Gram Matrix via Monopolar Representation
Authors: Kornprobst Jonas , Knapp Josef , Eibert Thomas F.
Published: June 2022

Starting from the monopolar representation of the Rao-Wilton-Glisson (RWG) functions, an approximate inverse (AI) of the RWG Gram matrix is constructed, where only 3x3 matrices for all individual triangles have to be inverted. The inversion of the Gram matrix is, however, only approximate, since it results as the inverse of a product of singular matrices, which is not easily obtained. The AI is shown to be an effective preconditioner for the RWG Gram matrix and is in particular useful for ill-conditioned Gram matrics on distorted meshes.

Published: June 2022

The generalized principle of pattern multiplication (GPPM) and its application to wide-angle scanning array are investigated. It includes the generalized element factor (GEF), generalized array factor (GAF), and their beam match condition. The GEF model based on the phase mode currents in an aperture is given. A phase-mode antenna (PMA) with dual ports is designed to realize GEF function in the unit aperture. The prototype of the PMA exhibits a main lobe scanning range of -43.9°  to 43.9°  at 2.4 GHz. A 1-D four-element phased array using the PMA with element spacing 0.7λ based on the GEF and the GPPM is designed to verify GPPM. The array can scan maximum to ±78° in the operating band. Furthermore, an improved compacted phase-mode antenna (ICPMA) is designed, which is capable of lobe steering too. And the linear array with elements spacing 0.4λ using ICPMA is constructed, which can scan maximum to ±76° with the 1st SLL -13.7 dB in experiment. The proposed phased array based on PMA, ICPMA verify the advantages of GPPM, and presents attractive features in future wireless communication and radar system.

Authors: Pratesi Giovanni , Franza Annarita
Published: June 2022

This article dealt with the history of the chemical cabinet established by the Grand Duke of Tuscany, Peter Leopold of Habsburg-Lorraine (1747–1792), at the Imperial and Royal Museum of Physics and Natural History in Firenze during his regency. To achieve this goal, it investigated untapped archival sources (e.g., administrative and commercial documents, minutes, correspondences, inventories) concerning the museum management from its foundation in 1775 to the departure of the Grand Duke for Vienna to be crowned as Holy Roman Emperor Leopold II in 1790. The article analyzed the chemical cabinet’s manuscript catalog, whose entire transcription is presented in the Supplementary Information Files. The work then examined the connections between the activities performed at the chemical laboratory and Peter Leopold’s interests in experimental chemistry. Concerning this research question, the scientific relationship he held with the naturalist Giovanni Valentino Mattia Fabbroni (1752–1822) – Vice-director and then Director of the Imperial and Royal Museum of Physics and Natural History – who helped the Grand Duke navigate all aspects of his interests in chemistry and natural sciences, was also discussed.

The presented article raises the problem of worldview transformations of the Soviet era. We are talking about changes associated with the era of "thaw", when on the initiative of the new leader of the CPSU M. Khrushchev Soviet society began to break free from Stalin's shackles of repressive pressure on consciousness, resulting in a whole galaxy of extraordinary thinkers of the word. The purpose of the author's research was to conduct a content analysis of literary journals and almanacs published during 1954—1959 in the regional branches of the Writers' Union of Ukraine. The author's attention includes publications stored in the funds of the State Archive of Printing of the Book Chamber of Ukraine named after Ivan Fedorov, in particular, such magazines as: "Kharkiv", "Crimea", "Literary Odessa", "Literary Donbass", "Literary Rivne Region", "Carpathians", "Lights of Zaporizhia", "Literary Podillya", "Lights of Dnieper", "Dоnbass", "Steppe", "Khmelnytsky Almanac", "Literary Sevastopol", etc. The author tried to combine the substantive characteristics of the latter into headings and, if possible, to classify them. Among the established and widely marked in all regional periodicals of the then Ukraine sections, first of all, the historical and local lore, literary and local lore, documentary and amateur directions were revealed and processed. In addition, the author paid attention to the bibliographic parameters of the regional periodicals of the USSR in 1954—1959, namely, circulation (in the annual dynamics of circulation), subscription campaigns, sales of magazines by means of retail trade, the cost of magazines and more. The presented article analyzes in detail the composition of the editorial boards of these publications. Given the low circulation of journals processed by the author, we can talk about their rarity and underutilization in the research field of modern Ukraine.

Priapism is a painful and pathological erection caused by various abnormalities in erectile hemodynamics [1]. There are several aetiologies of which the common long-term risk is to cause sequelae erectile dysfunction in 50 to 60% [1, 2, 3]. In Mali, the main cause of priapism is sickle cell anemia. Our objective is to study the socio-demographic, clinical and therapeutic aspects of priapism at the Fousseyni Daou hospital in Kayes. This was a cross-sectional and descriptive study involving a series of 21 patients. It lasted 56 months (April 2016 to February 2020); performed in the urology department of the Fousseyni DAOU hospital in Kayes. The inclusion criteria for the study were: records of patients who presented with priapism during the study period. Records of patients with intermittent priapism were excluded. Treatment consisted of a transglandular caverno-cancellous shunt type Ebbehoj to local anesthesia associated with drug treatment. The main reasons for seeing patients are pain and being in a state of priapism. The age group of 8 to 20 years was 52% and 71.4% of our patients presented sickle cell traits including SS phenotype: 19%, SC: 19% and AS phenotype: 33.3%. 42.9% of our patients presented a lack of erection after an episode of priapism. Delays of more than a week were observed in 3 patients. Prevention of these priapisms involves regular monitoring of sickle cell patients.

Published: June 2022

Significant differences exist between airways of the neonate and the adults. Anaesthetic management of airway may be challenging in neonates and young infants with large neck masses like cystic hygroma because these patients are at risk for sudden complete airway occlusion resulting in hypoventilation and hypoxemia. Cystic hygroma are benign, but can be disfiguring. It is a condition which usually affects children. Treatment is surgical excision under general anaesthesia either one or multistage resections.

Background: The enlargement of prostate is known as benign prostatic hypertrophy (BPH). It begins when the cells of the prostate gland begin to proliferate. BPH is caused by increased age and other factors associated with it. Objective: To determine the correlation of prostate volume with age and post-micturating residual (PMR) volume in patients with benign prostatic hyperplasia (BPH). Methods: This cross-sectional study was conducted on 100 patients of BPH that fulfilling inclusion criteria for 4 months, selected from Gondal Medical Complex Gujranwala during 14 January to 15 May 2022. Patients with prostate cancer, mild urinary tract or prostate surgery, and those with UTI or stone in bladder were excluded. Ultrasound was used to perform a transabdominal scan. Age, prostate volume (PV), and PMRV were the outcome parameters. Results: In this study hundred BPH positive patients were included. The mean age of patients with BPH, prostate weight, post-void residual volume of the participants was found to be 64.89±14.12 years, 54.68±29.42g, and 22.47±14.75ml respectively. In this study the correlation value of age of patients with BPH and prostate volume was 0.212 and P-value was 0.035 which was significant but the correlation between PV and PMRV was not significant because the correlation value of PV and PMRV was 0.032 and P-value was 0.751. Conclusion: This study concluded that there was significant correlation between Age and BPH but no significant correlation between BPH and PMRV.

Authors: Kaba Metin
Published: June 2022

Objective: Chorioamnionitis is a condition that bacteria infects the chorion and amnion and the amniotic fluid which can affect pregnant women. Infections may affect both the mother and fetus. Cervical insufficiency and chorioamnionitis cause preterm birth and perinatal morbidities.
Case: A 37-year-old patient was referred to the clinic with the diagnosis of preterm labor and cervical insufficiency at 26 weeks + 4 days of pregnancy. Cervix was 3 cm dilated, effaced 70%, the amnion membrane intact, and there was a cerclage thread on the cervix. There was a single, viable fetus in the uterine cavity with fetal measurements compatible with 27-28 weeks on ultrasonography. Ampicillin and azithromycin treatments were started. On the seventh day of observation, leukocytes and C reactive protein values had increased, and there was an onset of serohemorrhagic vaginal discharge. Thereupon, intravenous treatment of piperacillin/tazobactam and clindamycin started. Signs of chorioamnionitis were resolved. The patient was delivered on day 38 of admission due to vaginal bleeding. The newborn and patient outcomes were good. Further studies are needed to evaluate the new treatment regime's efficacy in chorioamnionitis treatment.
ВИЗНАЧЕННЯ ЗМІСТУ ТА СТРУКТУРИ ЛІКУВАЛЬНО-ОЗДОРОВЧОГО ТУРИЗМУ

Published: June 2022

У статті представлено наукову позицію автора щодо визначення сутності лікувально-оздоровчого туризму та його структури. Дослідження виходить з того, що однією з тенденцій розвитку світового туристичного ринку є стрімке зростання кількості подорожей з лікувально-оздоровчими цілями. Фактори, які детермінували це явище, об’єктивні: глобалізація, урбанізація, збільшення кількості людей похилого віку, поширення філософії здорового способу життя, зростання платоспроможності населення тощо. Найближчими десятиліттями потреба в лікувально-оздоровчих послугах буде зростати, що актуалізує питання кадрового забезпечення. В Україні ринок лікувально-оздоровчого туризму перебуває в стадії формування: санаторно-курортний туризм переживає спад, розвиток медичного, спа- та велнес-туризму стримується відсутністю правового забезпечення, їхні межі розмиті; панує термінологічна невизначеність. Це ускладнює освітній процес, особливо на спеціалізаціях з медичного та лікувально-оздоровчого туризму. Ґрунтовний аналіз наукових доробок зарубіжних та вітчизняних вчених показав, що основні дискусії виникають з приводу: 1) рамок лікувально-оздоровчого туризму: він обмежується лише лікувально-оздоровчими послугами (розглядається у вузькому значенні), чи об’єднує лікувальні, оздоровчі та лікувально-оздоровчі послуги (розглядається в широкому значенні); 2) його структури– виділяються два (лікувальний та оздоровчий) чи три (додається ще лікувально-оздоровчий) підвиди; 3) місце лікувально-оздоровчого туризму по відношенню до медичного, реабілітаційного, рекреаційного, спа- та велнес туризму. Обґрунтування позиції автора: на основі аналізу діючих нормативно-правових актів визначено юридично закріплену різницю між лікувальними та оздоровчими послугами. В першому випадку діяльність відбувається в двох секторах: медицина і туризм, і потребує оформлення відповідних дозволів. В другому – лише в сфері туризму. На основі цього, всі послуги, які так чи інакше пов’язані з системою охорони здоров’я, котрі планує отримати турист під час подорожі, розглядаються як складові лікувального туризму, який, у свою чергу, виступає підвидом лікувально-оздоровчого туризму (в широкому його значенні).

Визначено, що девальвація національної валюти, військові дії, зменшення доходів населення на сьогодні не дають можливості споживачам орієнтуватися на послуги індустрії гостинності в країнах ближнього та дальнього зарубіжжя. Досліджено розвиток індустрії гостинності в Україні. Визначено спад кількості зовнішніх та внутрішніх туристів у зв’язку з погіршенням соціально-економічного середовища в державі. Розглядаючи роль туризму в розвитку регіонального та національного господарства, доведено, що дана галузь на сьогодні є однією з провідних та тих, що може мати найбільш динамічний розвиток, серед галузей економіки. За швидким темпом зростання туризм в світі визнаний економічним феноменом століття. Туризм здійснює великий вплив на ключові сектори економіки, зокрема транспорт, зв’язок, будівництво, сільське господарство. Доведено ефективність інноваційного підходу в сфері індустрії гостинності, а саме створення комплексів відпочинку та туризму на засадах державно-приватного партнерства. Визначено основні напрями розвитку маркетингу інновацій в індустрії гостинності: надання доступних послуг з розміщення туристів (можливість самостійного приготування страв в номерах, мінімалістичний стиль номерів тощо); формування екскурсійних турів за доступними цінами (створення туристичних маршрутів в прилеглих територіях до місць розміщення); створення комплексів відпочинку в сільській місцевості з метою економії витрат на оренду, заробітну плату тощо); проведення маркетингових компаній з просування послуг в соціальних мережах з метою економії коштів на просування послуг); розвиток співпраці з місцевими територіальними громадами з метою залучення інвесторів в реконструкції пам’яток архітектору, які в перспективі можуть бути використанні, як місця проживання чи туристичних турів; формування комплексів відпочинку з повним переліком послуг (розміщення, екскурсії, послуги SPA, «зелений туризм» тощо). Запропоновано напрями розробки маркетингових інновацій дасть поштовх розвитку індустрії гостинності України, забезпечить потенційних споживачів якісними та прийнятними по ціні послугами, а також дасть можливість створити додаткові робочі місця в територіальних громадах та провести реконструкції занедбаних пам’яток архітектури.
