The unified corporate system of regulatory documents (CSRD) is created to solve the problems of regulatory support of enterprises and organizations of aircraft construction in Ukraine under the conditions of the law of Ukraine "On standardization". Corporate standardization can ensure the transition of all enterprises and organizations of the aircraft industry from using the system of state and industry standards of the former USSR to their system of standards, codes of practice, and other regulatory documents. To carry out work on the creation of the CSRD on the initiative of many enterprises in the industry, a Working Group was formed. By a common decision of the enterprises and organizations, the founders of the CSRD, the Head Organization for Corporate Standardization in the interests of enterprises and organizations of the aviation industry of Ukraine (HOS) was determined. It is planned to develop regulatory documents for CSRD by the Corporate Standardization Program and annual plans. For the formation and maintenance of the catalog of corporate regulatory documents and subscription services for the CSRD participants, it is planned to create a special Fund. Fundamental decisions on the CSRD will be made at the annual general meetings of the heads of enterprises and organizations that are members of the CSRD. Practical work on the creation of the CSRD began with the formation of arrays of existing regulatory documents planned for revision as corporate. To determine the regulatory documents that should acquire the status of corporate ones, a sectoral analysis of corporate regulatory documents was carried out, identifying priorities for two, three, four, or more enterprises, as well as for all CSRD participants. Also, a thematic analysis of industry standards was carried out using the example of standards used at the State Enterprise "Ivchenko-Progress". A thematic analysis of industry regulatory documents for prioritizing when they are converted to corporate status was carried out using information from the Classifier of State Standards (CSS). It is shown that the thematic analysis is more substantive to form the Corporate Standardization Program and annual work plans.

An experimental determination of the temperature dependences of the specific heat capacity and the thermal conductivity coefficient of the multifunctional coating MFP-92 at temperatures up to 1000 °C has been carried out. At temperatures up to 450 °C, an IT-c-400 device was used to determine the specific heat capacity. IT-l-400 device was used for the determination of thermal conductivity. At higher temperatures, the determination of the thermophysical characteristics (TPC) was carried out by solving the inverse problem of thermal conductivity (IPT) in a flat plate under conditions of one-sided heating in a muffle furnace. Composite material MFP-92 is a multilayer structure with upper layers based on silica fabric and chromophosphate binder and lower layers based on mullite-silica fabric and aluminosilicate binder. The TPC of the layers also differ from each other, and, accordingly, the properties of this material as a whole can be determined only in the form of their effective values, averaged in one way or another over the thickness of the coating. In addition, during heating, the material undergoes significant physicochemical transformations associated with the thermal destruction of its components, manifested in the form of abundant gas release, and a decrease in the density of the material, which significantly changes its TPC and determines its dependence on the heating rate. Therefore, studies of the thermophysical characteristics of the MFP-92 material were carried out with several (2-5) consecutive heating cycles. It was found that in four heating cycles of the MFP-92 material up to 450 °C for 75 minutes when measuring the specific heat on the IT-c-400 device, its temperature dependence significantly changes qualitatively and quantitatively. With furnace heating to 1000 °C, the temperature dependences of the TPC of the material, determined in the first and second heating cycles, have a different form, but change insignificantly in subsequent heating cycles. This makes it possible to ascribe to the MFP-92 material a set of two sets of TPC related to its initial (phase A) and annealed after heating to 1000 °C (phase B) states. Using the obtained TPС of phase A (including the magnitude of the thermal effect of irreversible endothermic phase transition at 100 °C) and phase B, good agreement was obtained between the calculated and experimental temperature fields in the samples under furnace heating conditions.

In many respects, the efficiency and economy of the aircraft are determined by the parameters and characteristics of the power plant. The analysis of trends in the world engine building shows that an increase in the bypass ratio can significantly increase the efficiency of engines. One of the possible technical solutions to ensure the high performance of the perspective engines with an ultra-high bypass ratio is the use of a ducted propeller or propfan. This solution allows you to reduce acoustic radiation. In addition, the main advantage of the ducted propfans is a certain increase in thrust for the same consumed power. When flowing around a ducted propfan, a significant suction force arises on the nose of the profiled ring, the projection of which on the direction of movement provides a positive thrust of the ring. The presence of a duct also leads to a decrease in the final loss of the propeller, which, in turn, leads to an increase in the efficiency of the engine. Ducted and unducted propfans with the same blade row are investigated to assess the characteristics of a ducted propfan. The researches were carried out by the method of numerical experiment. The object of the research is a propfan with an inlet diameter of 2.924 m and the number of blades of 14 for a turbofan engine with a bypass ratio of m = 30. To research the propfan characteristics, a cruising mode of operation was selected in the range of revolutions n = 1500 ... 1650 rpm. with Mach numbers at the input from M = 0.54 to M = 0.8. In this work, the calculation did not take into account the resistance force of the duct. For a qualitative assessment of the flow in the propfan, visualization of the flow lines in the ducted and unducted propfan was obtained. The analysis of the research results showed that for all modes of operation the ducted propfan has a thrust force higher than the unducted propfan. The increase in thrust load reaches 71 ... 76 %. Visualization of the flow lines when flowing around a ducted and unducted propfan showed that the presence of a duct improves the internal aerodynamics of the propfan.

The article considers the method of improving the characteristics of the ring inlet device, taking into account the influence of the propeller of an aircraft power plant with a turboprop engine. It is shown that increasing the total pressure loss in the inlet device by 5% increases, approximately, the specific fuel consumption by 3% and reduces engine thrust by 6%, and uneven flow at the inlet to the engine is the cause of unstable compressor of the turboprop engine. It is proposed to improve the characteristics of the input device by modifying the shape of its shell and channel. Evaluation of the influence of the shape of the shell and the channel of the annular axial VP on its main aerodynamic characteristics, taking into account the non-uniformity of the flow on the fan in the calculated mode of operation of the SU is carried out by calculating the full pressure recovery factor. The object of the study is an annular axial input device in front of which is a coaxial fan turboprop fan. The process of modeling the influence of the shape of the shell and the channel on the recovery factor of total pressure, circular and radial non-uniformity of the flow through the input device is implemented in the software system of finite element analysis ANSYS CFX. Geometric models of coaxial screw fan, fairing and inlet device are built in ANSYS SpaceClaim and transferred using the built-in import function in ANSYS Workbench. Block-structured grid models of air propellers of the first and second rows of the fan in the amount of 1.9 million, fairing and inlet device, in the amount of 3.9 million, are built in the ANSYS TurboGrid environment. The standard Stern (Shear Stress Transport) Gamma Theta Transition was used to close the Navier-Stokes equation system. Based on the results of mathematical modeling of flow in coaxial fans and subsonic ring inlet device on the maximum cruising mode of the turboprop engine, the full pressure recovery factor is calculated and it is established that the most influential factor that increases its full pressure recovery factor.

The effect of ionizing radiation on the organoleptic properties and shelf life of some vegetables (potatoes, onions, carrots and beets, tomatoes and sweet peppers) has been studied. Samples of vegetables were packed in special polymer dishes, and for the purpose of dosimetry, 3 ampoules containing 5 ml of purified benzene were placed next to the samples in each dish. Also, vegetable samples and ampoules were irradiated with doses of 0.5 kGy, 1.0 kGy, 3.0 kGy and 5.0 kGy of ionizing gamma radiation from 60Co sources of the sterilization installation on May 19, 2021. The surface and organoleptic properties of irradiated samples of vegetables placed in a dry, ventilated room, were periodically explored. After a while, deterioration of the organoleptic properties of some samples was recorded, and these samples with spoiled consumer properties were selected and removed from the room. The quantity of potatoes and onions with spoiled consumer properties from May 18, 2021 to August 15, 2021 among unirradiated samples and irradiated with absorbed doses of 3.0 and 5.0 kGy was approximately 30-40%. However, in contrast to the irradiated samples, a gradual germination of non-irradiated, unspoiled samples of potatoes and onion (kept under the same conditions as the irradiated samples) was observed in the reviewed period. Until August 15, 2021, no changes in the appearance and organoleptic properties of potato and onion samples irradiated with doses of 0.5 and 1.0 kGy were detected. It found that to prevent germination and to increase the shelf life of potatoes and onions, their irradiation with doses of 0.5 and 1.0 kGy was required; for a 2-3 fold rise in the shelf life of other types of vegetables, irradiation with absorbed doses of no more than 0.5 kGy is required

Indonesia Statistics on 2004–2007 states that pancreatic cancer is not included in the 10 cancers with the highest incidence. In West Kalimantan. There are no published data related to pancreatic cancer cases. This is the reason for the researchers because this data is sufficiently needed to support other studies related to pancreatic cancer.Methods: Epidemiological studies were conducted in the form of data collection at Dr. Soedarso Hospital Pontianak. Data were retrieved from cases of pancreatic cancer regression in annual Morbidity Data of Pancreatic Cancer Patients in Dr. Soedarso Hospital Pontianak from 2018 until 2009 consisting of the frequency of new cases and deaths, as well as demographic data such as age and gender of patients. Data were processed using Microsoft Excel.Results: A total of 79 cases and 9 deaths caused by pancreatic cancer were recorded in Dr. Soedarso Hospital Pontianak from January 2009 to December 2018. The highest incidence rates occurred in 2014 with 17 out of 79 cases (21.5%). As many as 63.3% of pancreatic cancer cases are dominated by men. Most cases of pancreatic cancer in patients with the age range of 45-64 years (67.1%) and the average age is 53.8 years.Conclusions: Incidence of pancreatic cancer in Dr. Soedarso Hospital Pontianak each year of 7.9 cases.

Myasthenia Gravis in Patients with Histopathologically Diagnosed Thymoma at Sanglah General Hospital: A Case Series
Authors: Saraswati Seputra Desak Putu Gayatri , Mahendra Dewi I Gusti Ayu Sri
Published: August 2021

Introduction: Thymoma is a neoplasm of the thymus gland which arises from the epithelial tissue. Thymoma is frequently related to various paraneoplastic syndromes, most commonly myasthenia gravis. Up to 50% of patients with thymoma are reported to develop myasthenia gravis, whereas 10–15% of patients with myasthenia gravis are found to have thymoma. Case Presentation: This case series reported 3 patients with myasthenia gravis which co-occurred with thymoma at Sanglah General Hospital from 2018 to 2019. The patients’ ages range from 33 to 61 years (mean age 46 ± 11 years) with a 2:1 male-to-female ratio. The diagnosis of myasthenia gravis was made by the presentation of typical myasthenia gravis appearances, the fluctuating intensity of ocular and bulbar muscle weakness (all three cases), and limbs and axial muscle weakness (one case); no respiratory muscle involvement was found. Physical and supporting examinations including electroneuromyography results were coherent with myasthenia gravis. The diagnosis of thymoma was made by highly suggestive appearance in Thorax Multi Sliced Computed Tomography (MSCT) scan examination and histopathologic findings. MSCT scan examination showed a well-circumscribed ovoid solid mass in the mediastinum (left anterosuperior, superior, and anterior to middle right mediastinum) sized from 1.8x1.5x2.9 cm to 8.1x9.9x9.7 cm, enhanced with contrast injection with areas of calcification and central necrotic (1 case) and no dissemination to regional lymph node and neighboring organs. All cases received acetylcholinesterase inhibitors and underwent extended thymectomy. Histopathological examination showed accordance with thymoma features of subtype A, AB, and B1.Conclusions: Clinicians should be aware of the thymoma and myasthenia gravis co-existence possibility to ensure early recognition and appropriate management.
A Case Report of 41-Year-Old Female with Fibrous Dysplasia Combined with Ethmoid Mucocele
Authors: Kang Seung Heon , Cha Hyunkyung , Han Seung Cheol , Kim Hyun Jik
Published: August 2021

Fibrous dysplasia (FD) is a non-malignant progressive condition, which replaces normal bone and marrow with fibrous tissue and woven bone. Sinus mucocele is a cystic, expansile, and destructive lesion that occurs as a result of obstruction of the sinus ostium secondary to inflammation, trauma, anatomical variation, previous sinus surgery, tumor or FD. Among them, FD combined with mucocele has been rarely reported. Here we report the first case of FD combined with ethmoid mucocele. The patient underwent endoscopic debulking of FD and marsupialization of mucocele. The mucocele was successfully marsupialized, and the patient’s symptoms were completely resolved. We propose a new hypothesis that nasal mucosa invaginates into FD and forms a mucocele. For the treatment of ethmoid FD combined with mucocele, we recommend an endoscopic transnasal approach for debulking and marsupialization.
Current Update of Local Allergic Rhinitis

Published: August 2021

Local allergic rhinitis (LAR) is a localized nasal allergic response in the absence of systemic atopy. The symptoms, duration, severity, and comorbidities of LAR are similar to those of allergic rhinitis. Although pathophysiology of LAR is not fully understood, in some patients specific IgE can be demonstrated in the nasal secretions. The diagnosis currently relies on the positive results of nasal provocation test. Nasal provocation test has shown high sensitivity and specificity with safety, and is considered as the gold standard. LAR patients benefit from the same therapeutic strategies as allergic rhinitis patients, including the avoidance of allergen exposure and the pharmacotherapy. Effectiveness and safety of allergen immunotherapy open a window of treatment opportunity in LAR. This review provides a current update on LAR.
Endocrine comorbidities of pediatric obesity
Authors: Lee Jieun , Kim Jae Hyun
Published: August 2021

Pediatric obesity has become a serious public health issue. The prevalence of obesity in children and adolescents has increased worldwide and in Korea over several decades. Obese children are more likely to be obese adults with an increased cardiovascular risk. Therefore, maintaining a healthy weight and preventing obesity during childhood are of critical importance. Moreover, obese children and adolescents often have endocrine comorbidities such as prediabetes, type 2 diabetes, dyslipidemia, metabolic syndrome, polycystic ovary syndrome, and central precocious puberty. Hence, the early implementation of obesity management using a multidisciplinary team approach and screening for these comorbidities in obese children and adolescents are required with the appropriate management of each comorbidity and/or specialist referral.
