Authors: Sohibi Maulana , Dermawan Denny , Lasmadi Lasmadi
Published: August 2020

Radar technology at several airports is still using flightradar24 as a source of information, and building an ADS-B station is expensive. However, the flightradar24 has several weaknesses, among which is that if the user wants to display more information, the user is required to pay periodically or subscriptions, and there is delay due to the process of data that requires the Internet connection. With a concept of receiver ads-b based RTL-SDR R820T2, a low cost receiver ads-b with the results can receive an ads-b signal without delay and can receive data from an airplane. But there is a weakness in rtl-b receivers based RTL-SDR R820T2, because it doesn't explain and can't know how far the receiver can receive signals and target parameters data from the aircraft. Thus on this research a receiver ads-b using RTL-SDR R820T2, with a low-noise amplification and an ads-b antenna 1090 MHZ in the hopes of knowing how far the aircraft's target range is from the receiver and knowing how far the receiver's range of data signals the target parameters. By performing some step-by-step testing of the design. The designed receiver ads-b USES low noise amplification with an ads-b antenna 1090 MHZ capable of receiving data and target parameters ads-b for 284 km on adsbSCOP software range and 287.63 km mathematically.

Published: August 2020

The article describes the specification of corporate conflicts from the position of the classic line of agency problem within the framework of the "Principal- Agent" model, and in the new line of agency model "Principal - Principal" between majority shareholders and minority shareholders, including shareholder interactions with stakeholders under the Principal-Stakeholders model and board interactions with stakeholders through Agent-Stakeholders, and interactions between company management, mid-level managers and employees within the Agency-Agent model, which makes it possible to classify different characteristics of corporate conflicts. The article clarifies the content and functional specifics of corporate conflicts (gnoseological function, diagnostic, procedural, preventive, predictive), which allows you to systematize the essential characteristics of corporate conflicts and determine the adaptability of the application of various methods and methods of their management taking into account the main stages of the life cycle of corporate conflicts (stage of emergence, development and completion).
The problem of risk management of business activities on the basis of estimates of financial statements
Authors: Serebryakova Tatyana , Suglobov Aleksandr , Fedosenko Tatyana
Published: August 2020

Business activities are characterized by risks, since all responsibility for an incorrect decision falls on the business entity with a loss. One of the necessary functions for business is to assess risks and develop solutions to minimize them or other strategies to limit the consequences of the negative impact of risk events. It is considered that organizations do not have the risk accounting system necessary to manage them. However, as the history of accounting development and its transformation into financial accounting shows, risks are successfully taken into account in system accounting. At the same time, we consider the risks of loss of asset value, return of accounts receivable, occurrence of additional obligations in excess of the usual ones, inflation risks, and some others. Their accounting methods are ambiguously regulated, and many problematic aspects remain, including the conceptual and methodological apparatus for risk accounting. Among the problems, management is not prepared to use the final information based on the results of risk accounting. This article is devoted to the consideration of these issues.

Higher education is one of the Central subsystems of the social segment of the country, which provides individuals with ways to obtain comprehensive theoretical and practical knowledge and skills for their effective implementation in a professional manner and to meet the many needs of the individual, the population and the state.

In the course of consumption, educational services are transformed into a labor force, whose quality indicators depend on both the unity of the provided educational services, and on the quantitative and qualitative criteria of personal labor that were spent during the process of receiving such services, the individual's abilities, and the level of their implementation.
The current leadership development opportunities provided for student paramedics by Higher Education Institutions: a literature review
Authors: Rae Alison , Robinson Simon
Published: August 2020

Introduction: The development of safe, competent and capable paramedics is one of the key concerns of education providers or Higher Education Institutions (HEIs). To achieve this, paramedic programmes need to focus on teaching leadership to students. The aim of this literature
review was to identify the current leadership development opportunities for paramedic students during their undergraduate training across the United Kingdom, in order to identify current gaps and make suggestions on how HEIs could increase leadership opportunities for student paramedics.Methods:
During August 2018, the Scopus, Medline, CINAHL and Academic Search Premier databases were searched (the last three accessed via EBSCOhost). Grey literature was also manually reviewed. Both authors screened the title and abstract and agreed on final papers eligible for full-text review. CASP
and COREQ checklists were used to assist in critically appraising the quality of the research and to help decide on the papers chosen for inclusion.Results: The search yielded 511 results (455 after duplicates were removed). The grey literature search also yielded one additional
document that incorporated a framework based on primary research integrated within the paper itself. After title and abstract review, seven papers were included for full text critical review. Two papers were then excluded, resulting in a total of five papers being included in the review.Conclusion:
Current evidence, although limited, demonstrates the benefit of educational programmes in developing educational and non-educational leadership opportunities for paramedic students. Moreover, there is value to individuals being provided or seeking extra-curricular activities, and students
should be encouraged to engage in societies, the College of Paramedics, events and conferences, and to work or volunteer in healthcare or emergency service-related sectors to further enhance their leadership potential and skills.

Published: August 2020

It was reported in 2005 during WHO survey that about 70-80% of the world population use medicinal plants either in their crude unmodified form or partially in their modified semi-synthetic form of plant sources in their primary healthcare. The present study investigated the phytochemicals and antimicrobial activities of the leaf extracts of Cerathoteca sesamoides and Chromolaena odorata to ascertain their potentials in herbal medicine. Fresh leaf of the plants obtained from Lafia in Nasarawa State, Nigeria were dried, powdered, and subjected to methanolic extraction, partition, phytochemical, and antimicrobial analyses using standard methods. Partitions from n-hexane, methanol, ethyl acetate, chloroform, and residue extracts were tested against clinical bacteria Escherichia coli, Klebsiella spp., Pseudomonas aeruginosa, Staphylococcus aureus, and fungus Candida albicans. Among the four different solvents used in partitioning methanolic and ethyl acetate extracts of both plants contain flavonoids, tannins, alkaloids, terpenoids, saponins, steroids, and cardiac glycosides. Saponins were absent in the n-hexane and chloroform extracts of C. odorata and the ethyl acetate extract of C. sesamoides. While flavonoids were present in the n-hexane extracts of C. odorata, they were absent in C. sesamoides. Anthraquinone and reducing sugar were absent in all the solvent extracts of both medicinal plants. The antimicrobial susceptibility tests showed that n-hexane and residue extracts of both plants had no activity against the tested microorganisms. The chloroform and ethyl acetate extracts of C. sesamoides and C. odorata (at 12.5 mg/ml) were active against all the tested clinical bacteria K. spp., E. coli, P. aeruginosa, S. aureus, and C. albicans. The methanolic extracts of both plants were active against the bacterial isolates but inactive against C. albicans. The minimum bactericidal concentration of these plant extracts was ≥50 mg, while the minimum inhibition concentrations ranged between 12.5 mg and ≥50 mg. The findings showed that the chloroform or ethyl acetate extracts of the leaves of these plant drugs could be used to treat urinary tract infections.

Authors: Teksoy Ozgun , Sahinturk Varol , CENGİZ Mustafa , İnal Behcet , Ayhancı Adnan
Published: August 2020

Background: The relationship between liver diseases and neurological defects is well established. Hepatic encephalopathy (HE) has been seen both in people with acute liver failure (ALF) and chronic liver disease (CLF). HE is a complex neuropsychiatric syndrome that is seen in patients suffering from liver dysfunction. Silymarin (Sm) has antioxidant, anti-inflammatory, and anti-carcinogenic features. In this study, the possible protective effects of silymarin were investigated against dorsolateral prefrontal cortex (DLPFC) damage induced by thioacetamide (TAA).

Method: To achieve this, male Sprague Dawley rats (200-250 g) were randomly divided into four groups, with 7 animals comprising each group: the control group, 50 mg/kg TAA group, 50 mg/kg Sm + TAA group, and 100 mg / kg Sm + TAA group.

Results: Differences between the groups were determined by performing immunohistochemical analysis of the PFC. Bax, TNF-α, and TUNEL expression increased in the brain tissue of the experimental group where only TAA was administered.

Conclusions: It was observed that in high doses in particular (100 mg/kg Sm + TAA group), Sm was effective in preventing PFC damage caused by TAA. It was determined that 100 mg/kg Sm significantly reduces TAA-induced inflammation (TNF-α and H&E) and apoptosis (Bax, TUNEL) in brain tissue.
Evaluation of Vocal Communication in a Robot Collective
Authors: ERBAŞ Mehmet Dinçer , PARLAK İsmail Hakkı
Published: August 2020

In this research, we attempt to design a model in which multiple robots communicate with an artificial proto-language whose symbols are vocally encoded letters of the Morse alphabet. We have shown that, as the robots have limited sensing and acting abilities, the communicated symbols of the proto-language differentiates from their original versions due to copying errors. We check the effects of two distinct environmental factors, namely the positional distance between the robots and the amount of noise in the environment. It is shown that both of these factors affect, in different ways, how accurately the presented proto-language can be accurately transmitted by the robots.

Authors: Karpovich A. A. , Shyshko V. I.
Published: August 2020

The aim of the present research was to assess the expression of melatonin receptors (MTNR1B) in the esophageal mucosa in the gastroesophageal reflux disease associated with obstructive sleep apnea/hypopnea syndrome and to study the relationship between the detected changes and the sleep apnea severity. 84 patients aged 30–60 years, including those with gastroesophageal reflux disease (group 1, n  =  25), those with gastroesophageal reflux disease associated with sleep apnea/hypopnea (group 2, n = 23), those with obstructive sleep apnoe/ hypopnoe syndrome (group 3, n = 18), and almost healthy people (group 4, n = 18), were studied. Diagnoses were based on endoscopic imaging and respiratory monitoring. The MTNR1B expression in the esophageal mucosa was determined by the immunohistochemical method using specific antibodies. The MTNR1 B expression was evaluated quantitatively using the computer program Aperio ImageScope _v9.1.19.1567. The obtained material was analyzed statistically using the software Statistica 10.0. The group 2 patients were shown to have a higher MTNR1B expression compared to the group 1 patients (0.122 [0.064; 0.266] versus 0.620 [0.332; 0.983]; p =  0.00001) and the group 3 patients (0.620 [0.332; 0.983] versus 0.232 [0.120; 0.418]; р = 0.0098). The MTNR1 B expression increased with growing sleep apnea severity: it is 0.295 [0.198; 0.403] in patients with mild apnea versus 0.941 [0.345; 0.992] in patients with moderate and severe apnea (p = 0.0021). A direct correlation between the MTNR1B expression and the sleep apnea severity degree (r = 0.50; р = 0.0016) was revealed. Patients with gastroesophageal reflux disease combined with sleep apnea revealed an increase in the MTNR1 B expression associated with the apnea severity. The revealed features of the MTNR1 B expression secondary to esophageal mucosal damage indicate the MTNR1 B inactivation secondary to accompanying apnea of hypoxia.
Brosimum alicastrum Swartz como alternativa para la reconversión productiva de áreas agrosilvopastoriles en Campeche

Published: August 2020

Respecto a la especie Brosimum alicastrum (Ramón) existen diversas investigaciones sobre sus propiedades nutracéuticas para la alimentación animal y humana, usos medicinales e incluso sistemas de producción. Sin embargo, sigue siendo un taxón, fundamentalmente, silvestre y de nulo manejo silvícola. En virtud de ello, el objetivo del presente trabajo fue analizar algunos de los factores económico-sociales, fisiográficos y de producción que determinan la reconversión de terrenos a plantaciones con Ramón, en el estado de Campeche. Mediante un muestreo dirigido a las zonas con mayor abundancia de la especie, se encuestaron entre septiembre y noviembre de 2018 a 190 productores de los sectores agrícola (94), pecuario (58), forestal (17) y apícola (21). Los resultados indicaron que la edad, escolaridad e ingreso económico familiar que representan los sistemas actuales de producción, no condicionan la reconversión. Por el contrario, aquellos que más la restringen se asocian con la libertad de decisión sobre sus parcelas (tenencia de la tierra), el acceso a las áreas donde B. alicastrum se distribuye de manera natural, y la falta de paquetes tecnológicos para su producción y poscosecha. Los productores con mayor disposición a reconvertir sus tierras son los agrícolas y pecuarios; los primeros incentivados por el posible precio de venta del kilogramo de semilla ($23.00 MN), y los segundos por la obtención de forraje alterno de menor costo. En ambos casos, la asesoría y capacitación técnica ayudarían a minimizar los tiempos de adaptación a los nuevos sistemas de producción.
Aspectos metodológicos para generar diagramas de manejo de la densidad de rodales con base en el índice de Reineke
Authors: Tamarit Urias Juan Carlos , Barraza Gerónimo Quiñonez , Ramos Jonathan Hernández
Published: August 2020

La densidad indica el grado de aglutinamiento de los árboles en un rodal, sus cambios afectan el rendimiento maderable y el tamaño de los individuos. El modelo de Reineke y su índice de densidad del rodal (IDR) se usan en la construcción de diagramas para manejar la densidad (DMD), el IDR define el límite superior del autoaclareo y el punto mínimo de ocupación total del sitio. A pesar de su importancia, en la construcción de un DMD es común que exista desconocimiento o poca claridad sobre aspectos metodológicos relevantes. El objetivo es presentar elementos teóricos básicos que el responsable del manejo forestal debe considerar para construir un DMD. Bajo el enfoque clásico de modelación de la función de Reineke, se abordan conceptos sobre densidad, el tipo y características de la fuente de información dasométrica por utilizar, la selección de sitios en alta densidad, el ajuste estadístico de la función, criterios metodológicos para desplazar y delimitar la línea de autoaclareo, y juicios para determinar las zonas de crecimiento de Langsater. Se resalta que la línea de autoaclareo puede delimitarse a partir de sitios de muestreo para inventario maderable, y los de densidad alta se seleccionan aplicando el enfoque del IDR máximo (IDRmáx); el método de mínimos cuadrados ordinarios lineales para ajustar la función de Reineke es robusto y corrige la heterocedasticidad. Para el crecimiento máximo en volumen, los rodales es factible manejarlos entre 35 y 65 % con respecto al IDRmáx. Los niveles óptimos de densidad deben determinarse por especie.

Published: August 2020

Background: The scientific-based jamu development program enables the development of medicinal plants in the traditional medicine system that eventual-ly can be used in the formal healthcare system. Baturraden and Sumbang are considered as areas with abundant plant biodiversity in Java, where the local community has used those plants for medicinal purposes.Objective: This study is conducted to qualitative and quantitatively record and conserve the knowledge of the Baturraden and Sumbang community on the utilization of plants for treating diabetes mellitus.Method: The data of the plant’s local names, plant organs, methods of prepara-tion, and routes of administration of the herbal preparations used for treating diabetes mellitus were collected through semi-structured interviews with 97 informants. The species use-value (SUV), the relative frequency of citation (RFC), and fidelity level (FL) of each species were calculated accordingly to determine their relative importance and value to the local community.Result: There were 11 plant species from 10 families mentioned. The most commonly used plant organ, preparation method, and administration route were leaves, decoction, and oral, respectively. The most important and valuable plants were including Piper ornatum (SUV = 0.19, RFC = 0.13, FL = 23.09%) and An-drographis paniculata (SUV = 0.09, RFC = 0.07, FL = 42.86%).Conclusion: As the most critical antidiabetic plant in the studied area, the decoction or infusion of Piper ornatum leaves is taken orally 1-2 times a day. However, there are no reports on its anti-diabetic-related activities available to date. In contrast, the uses of Andrographis paniculata as the antidiabetic agent has been widely proven. Baturraden and Sumbang people orally consumed the decoction of this plant’s leaves once a day for the said purpose

Published: August 2020

The aim of the study is to analyze the macroeconomic determinants of foreign direct investment in real estate sector (FDIRE) covering the period from 2003:01-2016:12 for Turkey. To this aim, Johansen cointegration test and VECM (cointegrated VAR) have been employed and also impulse response functions and forecasted error variance decompositions have been analyzed to shed light on the issue of the nexus between selected macroeconomic indicators and FDIRE. Empirical findings suggest that the number of one-year lagged tourist arrivals and real house rent is the most important and statistically significant determinants of foreign direct investment in Turkish real estate sector. The findings imply that real house rent shocks also have a positive and significant impact on real house price.

Objective: To present the clinical and functional results of surgical treatment of patients with chronic instability of the ankle using the arthroscopic Brostrom technique. Methods: This is a case series of patients who underwent surgical treatment for chronic instability of the lateral ligament of the ankle using the arthroscopic Brostrom technique. Clinical assessments of ankle stability were performed preoperatively and at the last follow-up using the American Orthopedic Foot and Ankle Score (AOFAS), a visual analog scale (VAS) for pain, and the anterior drawer and talar inversion tilt tests. Surgical complications and patient satisfaction ratings were also analyzed. Results: A total of 16 patients were analyzed, with a mean follow-up of 14 months. There was a statistically significant (p<0.001) improvement in mean AOFAS, which increased from 67.2 to 90.8 points and the mean VAS for pain score reduced from 6.5 to 1.5 points. All ankles were stable and had normal results for the anterior drawer test and the talar inversion tilt test. Three patients (19%) reported that resumption of sporting activities provoked subjective pain in the ankle, which improved progressively during follow-up. Two patients (12.5%) exhibited neurapraxia of the superficial peroneal nerve. A majority of the patients (81%) rated treatment as good or excellent. Conclusion: Treatment of chronic instability of the ankle ligament using the arthroscopic Brostrom technique restored ankle stability and achieved good clinical results. There was a high rate of early complications, but the majority were transitory and underwent complete remission during follow-up. Level of Evidence IV; Therapeutic Studies; Case Series.

Objective: The aim of this study was to present a case series of patients undergoing posterior tibial tendoscopy, assess their clinical outcome, and describe surgical findings and treatment complications. Methods: This is a clinical, retrospective, observational study of 11 consecutive cases of tenosynovitis of the posterior tibial tendon. All 11 patients underwent tendoscopy of the posterior tibial tendon. All procedures were performed by the same surgeon in 2 different hospitals. Minimum follow-up was 2 years. Results: All patients had their preoperative and postoperative AOFAS and VAS scores assessed. Both scores had an important improvement at 12 months that persisted at 24 months. Moreover, 72.72% of the patients were very satisfied with the procedure, and no patient reported to be dissatisfied. Additionally, 90.91% of the patients had no postoperative complications. The present results are consistent with those previously reported in the literature. Conclusion: Endoscopic or tendoscopic repair of the posterior tibial tendon is a simple and reproducible procedure that provides good functional and cosmetic outcomes with a low complication rate. It is important to increase the number of patients in this series in order to expand our conclusions. Level of Evidence IV; Therapeutic Studies; Case Series.

Objective: To assess the involvement of the hallux interphalangeal (IP) joint after first metatarsophalangeal joint (MTPJ) arthrodesis and propose a treatment consisting of MTPJ resection arthroplasty associated with phalangeal osteotomy or IP joint arthrodesis. Methods: We retrospectively analyzed 9 patients treated with MTPJ resection arthroplasty associated with phalangeal osteotomy or hallux IP joint arthrodesis from November 2006 to January 2017. Results: The main causes of MTPJ arthrodesis that subsequently evolved to IP involvement were severe hallux valgus and sequelae or complications of previous hallux valgus operations. Additionally, the reasons leading to rescue surgery were pain, deformity, and/or discomfort. Conclusion: This therapeutic modality is able to relieve symptoms by a simple procedure, with acceptable functional and estheticresults. Level of Evidence IV; Therapeutic Studies; Case Series.
